=====================================================================

This filing amends the Form 8-K Current Report filed by Enterprise Products Partners L.P. on September 20, 1999. Item 2. Acquisition or Disposition of Assets Acquisition of Tejas Natural Gas Liquids, LLC On September 17, 1999, Enterprise Products Partners L.P. ("Enterprise") acquired Tejas Natural Gas Liquids, LLC ("TNGL") from a subsidiary of Tejas Energy, LLC ("Tejas"), an affiliate of Shell Oil Company. Tejas has the opportunity to earn an additional 6.0 million contingent convertible special partnership units over the next two years upon the achievement of certain gas production thresholds under a 20 year natural gas processing agreement entered into among TNGL, Shell Oil Company and a number of its affiliates covering substantially all of the Shell entities' Gulf of Mexico gas production. The effective date of the transaction was August 1, 1999. TNGL engages in natural gas processing and natural gas liquid ("NGL") fractionation, transportation, storage and marketing in Louisiana and Mississippi. TNGL's assets include varying interests in eleven natural gas processing plants (including two under construction) with a combined gross capacity of 11.0 billion cubic feet per day (Bcfd) and net capacity of 3.1 Bcfd; four NGL fractionation facilities with a combined gross capacity of 281,000 barrels per day (BPD) and net capacity of 131,500 BPD; four NGL storage facilities with approximately 29.5 million barrels of gross capacity and 8.8 million barrels of net capacity; and over 2,100 miles of NGL pipelines (including a 11.5 percent interest in Dixie Pipeline). The 14.5 million convertible special units received by Tejas at closing represent a 17.6 percent equity ownership in Enterprise. These special units do not accrue distributions and are not entitled to cash distributions until their conversion into common units, which occurs automatically with respect to 1.0 million units on August 1, 2000 (or the day following the record date for determining units entitled to receive distributions in the second quarter of 2000), 5.0 million units on August 1, 2001 and 8.5 million units on August 1, 2002. If all of the 6.0 million contingent special convertible units are earned, Tejas' ownership interest in Enterprise would increase to 23.8 percent based on the currently outstanding units, and 1.0 million of the contingent units would convert into common units on August 1, 2002 and 5.0 million would convert on August 1, 2003. Under the rules of the New York Stock Exchange, conversion of the special units into common units requires approval of the Enterprise unitholders. The General Partner has agreed to call a special meeting of the unitholders of Enterprise for the purpose of soliciting such approval. EPC Partners II, Inc. ("EPC II"), which owns in excess of 81% of the outstanding common units, has agreed to vote its units in favor of such approval, which will satisfy the approval requirement. The $166 million cash portion of the purchase price was funded with borrowings under Enterprise's existing credit facility led by The Chase Manhattan Bank. The consideration for the acquisition was determined by arms-length negotiation among the parties.

Unitholder Rights Agreement In connection with the transactions described above, Tejas purchased from EPC II a 30% membership interest in Enterprise Products GP, LLC (the "General Partner"), which serves as the sole general partner of Enterprise, and entered into a Unitholder Rights Agreement with Enterprise, the General Partner, Enterprise Products Operating L.P., EPC II and Enterprise Products Company (the "Unitholder Rights Agreement"). The Unitholder Rights Agreement provides that as long as Tejas owns more than a 20% interest in the General Partner, it will be entitled to designate one-third of the General Partner's board of directors, and that as long as it owns at least a 10% interest in the General Partner it will also be entitled to designate two members of a newly created Executive Committee of the General Partner. Tejas' rights to board and committee representation would decrease if their ownership interest decreases. The Unitholder Rights Agreement provides that the General Partner will not permit Enterprise, Enterprise Operating or the General Partner to take certain actions without the consent of at least one of the Tejas designees on the Executive Committee, including, among other things, paying special distributions not in accordance with Enterprise's current cash distribution policy; material dispositions of assets; dispositions of assets that could adversely affect production or delivery of gas by Shell Oil Company or its affiliates in the Gulf of Mexico; material acquisitions; mergers or similar transactions; issuing partnership units in private financing transactions; incurrence of indebtedness in excess of certain limits; repurchases of partnership units other than in connection with employee benefit plans; entering into or modifying transactions with affiliates; and submitting matters to a unitholder vote. The foregoing limitations will terminate when the special units issued to Tejas have been converted to common units and the market price of the common units has exceeded $24 per unit for 120 consecutive calendar days (subject to certain extensions). Pursuant to the Unitholder Rights Agreement, the board of directors of the General Partner has been increased by three members to a total of nine, and Tejas has designated Charles R. Crisp, Curtis R. Frasier and Stephen H. McVeigh as its board designees. Tejas has designated Curtis R. Frasier and Stephen H. McVeigh to serve on the Executive Committee, with the Enterprise designees being Dan L. Duncan, O. S. Andras and Richard H. Bachmann. Mr. Crisp is President and Chief Executive Officer of Coral Energy LLC, an affiliate of Shell Oil Company, Mr. Frasier is Chief Operating, Administrative and Legal Officer of Coral Energy LLC, and Mr. McVeigh is Manager of Production and Surveillance (Gulf of Mexico) for Shell Offshore Inc. The Unitholder Rights Agreement grants EPC II certain rights to acquire Tejas' interest in the General Partner if Tejas disposes of its special or common units, and to acquire Tejas' special or common units if it wishes to dispose of them. Each of these purchase rights would also apply in the event of specified change of control events relating to Tejas. The Unitholder Rights Agreement grants Tejas preemptive rights to acquire additional units issued by Enterprise in private equity financing transactions, and grants Tejas the right to acquire all of the partnership units owned by EPC II, Enterprise Products Company and their affiliates if certain change of control events occur with respect to Enterprise. The Unitholder Rights Agreement provides that if Tejas sells any of the common units it receives upon conversion of the special units in specified types of sale transactions for less than $18 per unit within one year after the applicable conversion date for the special units in question, then Enterprise will pay to Tejas the difference between the sales price and $18, either in cash or in additional units at Enterprise's option.

Other Agreements In connection with the transactions described above, Enterprise entered into a Registration Rights Agreement with Tejas granting Tejas certain rights to require Enterprise to register for resale under the Securities Act of 1933 all of the common units issuable upon conversion of the special units, and certain "piggy back" rights to require Enterprise to include such common units in any registration begun by Enterprise. Also, the partnership agreement of Enterprise and the limited liability agreement of the General Partner were amended to give effect to the above transactions, including the issuance of the special units. The foregoing summaries of the Contribution Agreement governing the acquisition, the Unitholder Rights Agreement, the Registration Rights Agreement, the amended partnership agreement of Enterprise and the amended limited liability company agreement of the General Partner are qualified in their entirety by reference to the complete documents.

TEJAS NATURAL GAS LIQUIDS, LLC NOTES TO STATEMENTS FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996 - -------------------------------------------------------------------------------- 1. ORGANIZATION AND BASIS OF PRESENTATION TejasNatural Gas Liquids, LLC ("TNGL" or the "Company") is a wholly owned subsidiary of Tejas Midstream Enterprises, LLC ("TME"), which is an affiliate of Shell Oil Company ("Shell"). The Company was formed on January 7, 1998 in connection with Shell's contribution of certain of its interests in natural gas processing plants, natural gas liquids ("NGLs"), fractionation facilities and pipelines, and NGL marketing activities which were previously part of approximately eight separate Shell divisions. The various assets owned and operated by TNGL are located in Louisiana and Mississippi. As of July 31, 1999, TNGL distributed to its parent all of its interests in Tejas Biogas, LLC, Tejas C Gas Plants LP, LLC, Texas Gas Plants GP, LLC, and Tejas Sheridan Pipeline, LLC, and its subsidiary, Texas Gas Plants, L.P. The Company also transferred certain other assets and liabilities to its parent. In addition, pursuant to a Contribution Agreement (dated September 17, 1999) by and among TME, Tejas Energy, LLC, Enterprise Products Partners L.P. ("EPD"), Enterprise Products Operating L.P., Enterprise Products Company, Enterprise Products GP, LLC and EPC Partners II, Inc., effective August 1, 1999, TME contributed the limited liability company interest of TNGL and its subsidiaries to EPD for cash and certain of EPD's general and limited partnership units as defined in the Contribution Agreement. The sale closed on September 20, 1999. The assets acquired under the Contribution Agreement included the TNGL assets and liabilities (the "TNGL Assets'), located in Louisiana and Mississippi, which includes: (a) interest in a number of gas processing and fractionation facilities and related assets; (b) NGL pipelines and (c) additional assets including transportation and terminalling assets required to support the NGL marketing operations and certain related contracts and working capital. The accompanying statement of assets acquired and liabilities assumed represents the assets and liabilities of the TNGL Assets at their historical cost. The statements of revenues and direct operating expenses include only those amounts related to the operations of the TNGL Assets and do not include selling, general and administrative allocations from the parent company. Historically, the Company has provided service and support functions for Shell's integrated operations. In this role, the strategic direction and economic development of the Company has been for the sole benefit of Shell. Consequently, certain business decisions made in periods of volatile market conditions were influenced by Shell's integrated operations and strategic direction and, as such, were not necessarily made autonomously for the profit of the individual assets. As a result, these statements are not necessarily indicative of the financial condition or results of operations that would have resulted had the TNGL Assets been operated as a stand-alone entity. Additionally, the distinct and separate accounts necessary to present an individual balance sheet as of December 31, 1998 and the related statements of income and of cash flows for the years ended December 31, 1998, 1997 and 1996 in accordance with generally accepted accounting principles have not been maintained and, therefore, are not presented. 2. SIGNIFICANT ACCOUNTING POLICIES Investments in Unconsolidated Affiliates - The accompanying statements include the accounts of the TNGL Assets and those of 50% or more owned subsidiaries controlled by the Company and also part of the TNGL Assets. The equity method is used to account for investments in unconsolidated entities in which the Company owns more than 20% of the voting interest but by definition does not have control. The cost method is used to account for investments in unconsolidated affiliates in which the Company owns less than 20% of the voting interest and by definition does not execute control. Inventories - Inventories consisting of NGLs and NGL products are carried at the lower of cost, on a last-in first-out (LIFO) basis, or market, and include certain costs directly related to the production process. The replacement cost of the inventory at December 31, 1998 was approximately $18.0 million. Property, Plant and Equipment - Property, plant and equipment is recorded at cost and is generally depreciated using the straight-line method over the assets' estimated useful lives. Some processing facilities are depreciated on a units-of-production basis to the extent that the processing facilities' sole operations are directly related to specific gas-producing properties. The unit-of-production rate is based on total proven reserves related to the dedicated gas producing properties. Maintenance and repair costs are expensed as incurred; additions, improvements and replacements are capitalized. Variable Ownership Percentage Adjustments - The ownership percentage of certain natural gas processing plants varies according to the plants' gas throughput associated with the Company. These plants are jointly owned with other entities which pay or are reimbursed by the Company to adjust the ownership percentage on an annual basis. Long-Lived Assets - The Company records impairment losses on long-lived assets if the carrying amount of such assets, grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows from other assets, exceeds the estimated undiscounted future cash flows of such assets. Measurement of any impairment loss is based on the fair value of the asset. For the years ended December 31, 1998, 1997 and 1996, there were no charges for impairments included in the statements of revenues and direct operating expenses. Excess Cost Over Underlying Equity in Net Assets - The excess of the Company's cost over the underlying equity in net assets of K/D/S Promix, LLC, is being amortized using the straight-line method over the estimated remaining life of the assets over a period not to exceed 20 years. Such amortization is reflected in the equity earnings from unconsolidated affiliates. The unamortized excess was approximately $20.3 million at December 31, 1998. Revenue Recognition - Revenue from processing and fractionation services is recognized when the services are provided. Revenue from the sale of natural gas liquids is generally recognized upon the passage of title. Revenue from pipeline transportation of natural gas liquids is recognized upon receipt of the natural gas liquids into the pipeline systems. Federal Income Taxes - The Company is a limited liability company and is, therefore, not taxable for federal tax purposes; as a result, income taxes have been excluded from the statements. Use of Estimates - The preparation of statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the statements, and the related reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.

Significant Risks - The Company is subject to a number of risks inherent in the industry in which it operates, primarily fluctuating gas and liquids prices and gas supply. The Company's financial condition and results of operations will depend significantly on the prices received for NGLs and the price paid for gas consumed in the NGL extraction process. These prices are subject to fluctuations in response to changes in supply, market uncertainty and a variety of additional factors that are beyond the control of the Company. In addition, the Company must continually connect new wells through third-party gathering systems which serve the plants in order to maintain or increase throughput levels to offset natural declines in dedicated volumes. The number of wells drilled by third parties will depend on, among other factors, the price of gas and oil, the energy policy of the federal government, and the availability of foreign oil and gas, none of which is within the Company's control. Recently Issued Accounting Standards - On June 6, 1999, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of the Effective Date of FASB Statement No. 133 - an amendment of FASB Statement No. 133," which effectively delays and amends the application of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," for one year, to fiscal years beginning after June 15, 2000. Management is currently studying this item to determine the financial statement impact of adopting SFAS No. 133. Dollar Amounts - Amounts presented in the tabulations within the notes to the statements are stated in thousands of dollars, unless otherwise indicated. 3. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment and accumulated depreciation at December 31, 1998 were as follows: Estimated Useful Life Description (in Years) Plants 15 - 20 $ 99,673 Pipelines 10 - 20 21,497 Transportation equipment 22 3,313 Land 175 Construction-in-progress 54,186 ------ Total property 178,844 Accumulated depreciation (79,239) Property, net $ 99,605 ======== 4. INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED AFFILIATES At December 31, 1998, the Company's significant unconsolidated affiliates included the following: K/D/S Promix, LLC ("Promix") - A 33.33% economic interest in a Limited Liability Company ("LLC") owning a fractionation plant and related pipeline and storage facilities near Napoleonville, Louisiana. The economic interest was acquired during 1997. The LLC is owned by three entities and operated by Koch Hydrocarbon Southeast, Inc. At December 31, 1998, the Company had a payable to Promix for capital expansions. Dixie Pipeline Company ("Dixie") - An 11.5% economic interest in a corporation owning a 1,300-mile propane pipeline and the associated facilities extending from Mt. Belvieu, Texas, to North Carolina. Dixie has seven owners, and Phillips Pipeline Company is the operator of the assets. Venice Energy Services Company, LLC ("Vesco") - A 13.1% economic interest in an LLC owning a natural gas processing plant with processing capacity of 1,300 MMCF/day, fractionation facilities, storage, and gas gathering pipelines in Louisiana. Vesco is jointly owned by five entities including TNGL. Dynegy Midstream Services L.P. is the operator of the assets. Tri-States NGL Pipeline, LLC ("Tri-States") - A 16.7% economic interest in an LLC owning a 161-mile NGL pipeline which stretches from Mobile Bay, Alabama, to Kenner, Louisiana. The pipeline construction started in the latter part of 1997 and was completed in January 1999. Tri-States is owned by six entities, including TNGL, and WSF-NGL Pipeline Company, Inc. ("Williams") is the operator of the assets. Because the Tri-States LLC agreement was not signed until January 1999, payment for a portion of its capital contribution by TNGL was recorded as an advance payable to unconsolidated affiliates as of December 31, 1998. Belle Rose NGL Pipeline, LLC ("Belle Rose") - A 41.7% economic interest in an LLC owning a 48-mile NGL pipeline extending from Kenner, Louisiana to Belle Rose, Louisiana. The pipeline construction began during the latter part of 1997 and began operations during March 1999. At December 31, 1998, the LLC agreement was not finalized. As a result, payment by TNGL has not been made for the investment in Belle Rose. Consequently, a payable was recorded as advances payable to unconsolidated affiliates as of December 31, 1998. Belle Rose will be owned by three entities, including TNGL, with TNGL being the operator of the assets. Following is a summary of the Company's investments in and advances to unconsolidated affiliates at December 31, 1998: Unconsolidated Affiliates -------------------------------------------- -------------------------------------------- Investments in Advances and Advances To Payable To Promix $60,610 $ 7,000 Dixie 10,639 Vesco 1,345 Tri-States 13,058 13,058 Belle Rose 11,137 11,137 ------ ------ Total $96,789 $31,195 ======= =======

Equity earnings from unconsolidated affiliates for the years ended December 31, 1998, 1997 and 1996 are as follows: Unconsolidated Affiliates ---------------------------------------------------------------- 1998 1997 1996 ------------------------------ ---------------------------- ------------------ Dividend Equity in Dividend Equity in Dividend Income Earnings Income Earnings Income -------------- ------------- ----------- ------------- ------------------ Promix $1,592 $3,100 Dixie $1,373 $903 $1,081 Vesco 3,088 Tri-States Belle Rose -------- -------- -------- -------- -------- Total $4,461 $1,592 $903 $3,100 $1,081 ====== ====== ==== ====== ====== Following is selected financial data for Promix, the most significant investment of the Company: BALANCE SHEET DATA 1998 Current assets $ 12,801 Property, plant and equipment, net 114,945 ------- Total assets $127,746 ======== Current liabilities $ 30,533 Members' equity 97,213 ------ Total liabilities and members' equity $127,746 ======== INCOME STATEMENT DATA 1997 1998 Revenues $24,563 $ 23,994 Expenses 12,639 16,009 ------ ------ Net income $11,924 $ 7,985 ======= ======== 5. RELATED-PARTY TRANSACTIONS Sales to Affiliates - The Company has transactions in the normal course of business with the unconsolidated affiliates and other subsidiaries and divisions of Shell. Such transactions include the buying, selling and transportation of NGL products. Products sold to related parties during 1998, 1997 and 1996 amounted to $168.8 million, $250.5 million and $312.6 million, respectively. Purchase of Raw Materials and Products - A contract exists between the Company and other Shell affiliates to allow processing of natural gas owned by Shell in the Company's operated and outside operated plants. Under this agreement, the Shell affiliates are paid for the gas volumes lost in processing at market prices. In addition, affiliates are reimbursed for any additional royalty expense as a result of processing the gas. In return, the Company receives 100% of the liquids extracted in these plants. Also, the Company purchases NGL products from unconsolidated affiliates and other subsidiaries and divisions of Shell. During 1998, 1997 and 1996, the Company paid Shell and its affiliates $377.1 million, $492.3 million and $466.3 million, respectively, representing raw material and product purchases. Cost Allocations - The Company has no employees. All individuals who perform the day-to-day operational functions are employed by affiliates of Shell. However, all direct operational salary costs are directly passed through to the Company and, therefore, do not represent partial allocations. 6. COMMITMENTS AND CONTINGENCIES Capital Expenditures Commitments - As of December 31, 1998, the Company had capital expenditures commitments totaling approximately $ 38.3 million, the majority of which relates to the construction of projects of unconsolidated affiliates. Litigation - The Company is sometimes named as a defendant in litigation relating to its normal business operations. Although the Company insures itself against various business risks, to the extent management believes it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to indemnify the Company against liabilities arising from future legal proceedings as a result of its ordinary business activity. Except for the note below, management is aware of no significant litigation or audit claims, pending or threatened, that would have a materially adverse effect on the Company's financial position or results of operations. The State of Louisiana has conducted an audit of fuel gas consumed in plant operations. Consumption of this fuel gas was exempt from taxation prior to 1987. However, in 1987 the state rescinded the fuel tax exemption, thus making the gas subject to tax at 3% of its value. The audit period reviewed by the state was January 1991 through December 1994 and included TNGL operated plants (Toca, Calumet and North Terrebone). The state claims TNGL Assets owes approximately $4.6 million in tax, interest and penalties based on total fuel gas usage at those plants for this period. However, it is expected that TNGL's tax liability will only be equivalent to its ownership in these plants. It also appears TNGL will be liable for tax on its share of the fuel at outside-operated plants located in Louisiana in which TNGL owns an interest. Although the ultimate liability is difficult to determine, the Company has $4.0 million included in accrued expenses as of December 31, 1998 which represents the Company's share of tax on fuel consumed at the operated as well as the outside-operated properties for the period from 1991 through 1998, including interest. 7. FAIR VALUE OF FINANCIAL INSTRUMENTS The disclosure of the estimated fair value of accounts receivable and accounts payable was determined by the Company using available market information and appropriate valuation methodologies. Considerable judgment, however, is necessary to interpret market data and develop the related estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Company could realize upon disposition of the financial instruments. The use of different market assumptions and/or estimation methodologies could have a material effect on the estimated fair value amounts. Accounts receivable and accounts payable are carried at amounts that approximate their fair value. 8. CONCENTRATION OF CREDIT RISK Substantial portions of the Company's revenues are derived from the fractionation, processing, marketing and transportation of NGLs to various companies in the NGL industry located in the United States. Although this concentration could affect the Company's overall exposure to credit risk, since its customers might be influenced by similar economic or other conditions, management believes that the Company is exposed to minimal credit risk, because the majority of its business is conducted with major companies within the industry and much of the business is conducted with companies with whom the Company has joint operations. The Company generally does not require collateral for its accounts receivable. ******

HOU04:132863.11 38

Section Indemnification Procedure. The party or parties making a claim for indemnification under this Article VIII shall be, for the purposes of this Agreement, referred to as the "Indemnified Party" and the party or parties against whom such claims are asserted under this Article VIII shall be, for the purposes of this Agreement, referred to as the "Indemnifying Party." All claims by any Indemnified Party under this Article VIII shall be asserted and resolved as follows: (a) In the event that (i) any claim, demand or Proceeding is asserted or instituted by any Person other than the parties to this Agreement or their Affiliates which could give rise to Damages for which an Indemnifying Party could be liable to an Indemnified Party under this Agreement (such claim, demand or Proceeding, a "Third Party Claim") or (ii) any Indemnified Party under this Agreement shall have a claim to be indemnified by any Indemnifying Party under this Agreement which does not involve a Third Party Claim (such claim, a "Direct Claim"), the Indemnified Party shall, with reasonable promptness, send to the Indemnifying Party a written notice specifying the nature of such claim, demand or Proceeding and the amount or estimated amount thereof (which amount or estimated amount shall not be conclusive of the final amount, if any, of such claim, demand or Proceeding) (a "Claim Notice"), provided that a delay in notifying the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Agreement except to the extent that (and only to the extent that) such failure shall have caused the Damages for which Indemnifying Party is obligated to be greater than such Damages would have been had the Indemnified Party given the Indemnifying Party proper notice. (b) In the event of a Third Party Claim, the Indemnifying Party shall be entitled to appoint counsel of the Indemnifying Party's choice at the expense of the Indemnifying Party to represent the Indemnified Party in connection with such claim, demand or Proceeding (in which case the Indemnifying Party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by any Indemnified Party except as set forth below); provided that such counsel is reasonably acceptable to the Indemnified Party. Notwithstanding an Indemnifying Party's election to appoint counsel to represent an Indemnified Party in connection with a Third Party Claim, an Indemnified Party shall have the right to employ separate counsel, and the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel selected by the Indemnifying Party to represent the Indemnified Party would present such counsel with a conflict of interest or (ii) the Indemnifying Party shall not have employed counsel to represent the Indemnified Party within a reasonable time after notice of the institution of such Third Party Claim. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any claim, demand or Proceeding which the Indemnifying Party defends, or, if appropriate and related to the claim, demand or Proceeding in question, in making any counterclaim against the Person asserting the Third Party Claim, or any cross-complaint against any Person. No Third Party Claim may be settled or compromised (i) by the Indemnified Party without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed or (ii) by the Indemnifying Party without the prior written consent of the HOU04:132863.11 39

Indemnified Party, which consent shall not be unreasonably withheld or delayed. In the event any Indemnified Party settles or compromises or consents to the entry of any Judgment with respect to any Third Party Claim without the prior written consent of the Indemnifying Party, each Indemnified Party shall be deemed to have waived all rights against the Indemnifying Party for indemnification under this Article VIII. (c) In the event of a Direct Claim, the Indemnifying Party shall notify the Indemnified Party within 30 Business Days of receipt of a Claim Notice whether or not the Indemnifying Party disputes such claim. (d) From and after the delivery of a Claim Notice under this Agreement relating to a Third Party Claim, at the reasonable request of the Indemnifying Party, each Indemnified Party shall grant the Indemnifying Party and its representatives all reasonable access to the books, records and properties of such Indemnified Party to the extent reasonably related to the matters to which the Claim Notice relates. All such access shall be granted during normal business hours and shall be granted under conditions which will not unreasonably interfere with the business and operations of such Indemnified Party. The Indemnifying Party will not, and shall require that its representatives do not, use (except in connection with such Claim Notice) or disclose to any third Person other than the Indemnifying Party's representatives (except as may be required by applicable Law) any information obtained pursuant to this Section 8.03(d) which is designated as confidential by an Indemnified Party. Section Survival. The representations and warranties of the parties contained in this Agreement shall terminate at and not survive the Closing; provided that the Tejas Representations and Warranties and the Enterprise Representations and Warranties shall each survive the Closing for the periods set forth below: (a) the representations and warranties of Tejas and Tejas Energy in Sections 3.04, 3.05, 3.07, 4.02, 4.06(a) and 4.12(a), (b) and (d) and 4.17 and the representations and warranties of the Enterprise Parties, EPC II, and Enterprise Products in Sections 5.03, 5.04, 5.09 and 5.13 shall survive the Closing until the second anniversary of the Closing Date; (b) the representations and warranties of Tejas and Tejas Energy in Section 4.07 and of the Enterprise Parties in Section 5.08 shall survive the Closing until the expiration of the applicable Tax Statute of Limitations Date; and (c) the representations and warranties of Tejas and Tejas Energy in Sections 3.01, 3.02, 3.03, 3.08, 4.01, and 4.11 and the representations and warranties of the Enterprise Parties, EPC II and Enterprise Products in Sections 5.01, 5.02, 5.10 and 5.12 shall survive the Closing for the applicable statute of limitations. Following the Closing, no party shall have the right to make any claim for indemnification for any representations or warranties under this Agreement which do not expressly survive the Closing or HOU04:132863.11 40

after the expiration of the applicable survival period thereof; provided that, with respect to any representation or warranty that survives the Closing in respect of which indemnity may be sought under this Agreement, such representation or warranty shall survive the time at which it would otherwise terminate pursuant to the preceding sentence, only if a bona fide, written notice of the inaccuracy of such representation or warranty giving rise to such right of indemnity (including the specific nature of such inaccuracy) shall have been given to the party against whom such indemnity may be sought prior to such time. The covenants and agreements of the parties (including, without limitation, the covenants and agreements of the parties set forth in this Article VIII) contained in this Agreement or in any other Transaction Agreement shall survive the Closing indefinitely. Section Limitation on Claims. (a) Each party hereto acknowledges and agrees that (except as set forth in subsection (d) below), the provisions of this Article VIII shall be the exclusive remedy of such party with respect to any matter arising under this Agreement; provided, however, that (i) the foregoing shall not limit the right of any such party to seek any equitable remedy (including specific performance) available to enforce the rights of such party under this Agreement or any other Transaction Agreement in accordance with the terms of this Agreement and (ii) nothing herein is intended to restrict the rights of Tejas (or its Affiliates) as a unitholder under the Enterprise Partners Amended Partnership Agreement, applicable securities laws or otherwise arising independently of this Agreement. (b) The liability of Tejas or Tejas Energy for Damages for breaches of any Tejas Representations and Warranties pursuant to Section 8.02(a), other than with respect to breaches of Sections 3.02, 3.08 and 4.07 shall be limited as follows: (i) Tejas and Tejas Energy shall not be liable for or have responsibility for any such Damages until the aggregate of such Damages incurred by the Enterprise Indemnified Parties with respect to such claims exceeds $8,000,000 in the aggregate and then only to the extent of the excess over such amount; and (ii) The obligations and total liability of Tejas and Tejas Energy for such Damages shall not exceed $60,000,000 in the aggregate. (c) The liability of any of the Enterprise Parties, EPC II or Enterprise Products for Damages for breaches of any Enterprise Representations and Warranties pursuant to Sections 8.01(i)(a), (ii)(a), and (iii)(a), other than with respect to Sections 5.08, 5.10(f) and (g) and 5.12 shall be limited as follows: (i) None of the Enterprise Parties, EPC II or Enterprise Products shall be liable for or have responsibility for any such Damages until the aggregate of such Damages incurred by the Tejas Indemnified Parties with respect to such claims HOU04:132863.11 41

exceeds $8,000,000 in the aggregate, and then only to the extent of the excess over such amount; and (ii) The obligations and total liability of the Enterprise Parties, EPC II and Enterprise Products for such Damages shall not exceed $60,000,000 in the aggregate. (d) Nothing in this Section 8.05 shall prevent any party from making a claim against the other party for actual and intentional fraud (as opposed to a fraud claim based on constructive knowledge, or negligent misrepresentation or similar theory). Section Tejas Environmental Indemnity. (a) Subject to the limitations set forth in Section 8.06(b) below, Tejas and Tejas Energy agree, jointly and severally, to indemnify and hold harmless each of the Enterprise Indemnified Parties from and against all Damages to the extent resulting from or arising out of Tejas Third-Party Environmental Claims made against the Company (or its successors or assigns) or any of its Subsidiaries or any of the Enterprise Indemnified Parties following the Closing Date. For purposes hereof, "Tejas Third-Party Environmental Claims" shall mean (x) a bona fide claim by a third party (other than a Governmental Authority acting in its regulatory capacity) alleging property damage resulting from exposure to Hazardous Substances prior to the Closing Date from properties owned by the Company or its Subsidiaries on or prior to the Closing Date and (y) a written directive from a Governmental Authority requiring remediation of properties owned by the Company or its Subsidiaries on or prior to the Closing Date pursuant to Environmental Laws in effect at the Closing Date. (b) The liability of Tejas or Tejas Energy for Damages under this Section 8.06 shall be limited as follows: (i) Tejas and Tejas Energy shall not be liable or have responsibility for any Damages under this Section 8.06 until the aggregate Damages incurred by the Company and its Subsidiaries with respect to all Tejas Third-Party Environmental Claims exceed $5,000,000 in the aggregate and then only to the extent of the excess over $5,000,000. Individual Tejas Third-Party Environmental Claims shall not be included in the $5,000,000 deductible until the Company or its Subsidiaries incurs Damages in excess of $500,000 with respect to such Tejas Third-Party Environmental Claim and then only to the extent of the excess over the $500,000 deductible. (ii) The obligations and total liability for Damages of Tejas and Tejas Energy under this Section 8.06 shall not exceed $100,000,000 in the aggregate.

with respect to bona fide claims for indemnification made in writing prior to such date which remain unresolved as of such date. (c) The Enterprise Indemnified Parties acknowledge and agree that the liability of Tejas, Tejas Energy or any of their Affiliates (other than the Company and the Subsidiaries) for Damages resulting out of or relating to environmental claims, matters or liabilities (including violations of Environmental Law and required remediation of properties due to the presence of Hazardous Substances in the soil, groundwater or surface water) shall be governed exclusively by the indemnification provisions contained in this Section 8.06. (d) With regard to all Tejas Third Party-Environmental Claims, the Enterprise Indemnified Parties shall give written notice identifying such claim to Tejas and Tejas Energy so that Tejas or Tejas Energy may participate, at its expense, in any discussions or negotiations with any applicable Governmental Authority concerning the remediation plan or project. Section Enterprise Contingent Environmental Payment. (a) If, following the Closing Date, any of Enterprise Partners, Enterprise Operating or any of their respective Subsidiaries or Enterprise GP incurs any Damages with respect to Enterprise Third-Party Environmental Claims (the "Enterprise Environmental Payments") then the Enterprise Parties shall within 20 days following such Enterprise Environmental Payment make a payment to Tejas (or its successors or designees) equal to 25% of such Enterprise Environmental Payment (the "Contingent Environmental Payments"). For purposes hereof, "Enterprise Third-Party Environmental Claims' shall mean (x) a bona fide claim by a third party (other than a Governmental Authority) alleging personal injury or property damage resulting from exposure to Hazardous Substances prior to the Closing and (y) a written directive from a Governmental Authority requiring remediation of properties, now, previously or hereafter, owned by the Enterprise Parties or any of their Subsidiaries; provided, however, that the term Enterprise Third-Party Environmental Claim shall not include any matters relating to the properties or assets included in the Business as contemplated by this Agreement. (b) The obligation of the Enterprise Parties to make the Contingent Environmental Payments will be subject to the following limitations: (i) The Enterprise Parties shall not be required to make any Contingent Environmental Payments under this Section 8.07 until the aggregate Damages incurred by the Enterprise Parties with respect to all Enterprise Third-Party Environmental Claims exceeds $5,000,000 in the aggregate.

Such right to purchase may be exercised by Enterprise Partners (or its designee) by giving notice to Tejas Energy that Enterprise Partners (or its designee) has elected to acquire the Tejas Units. The purchase and sale contemplated by the exercise by Enterprise Partners (or its designee) of such purchase right shall be completed at a closing that shall occur within 30 days after the written notice by Enterprise Partners (or its designee) electing to exercise such purchase right (or, if later and if Section 3.3(d)(ii) applies, within 15 Business Days after the determination of the Designated Purchase Price in accordance with Section 3.1), by (i) the transfer and assignment by Tejas Energy to Enterprise Partners (or its designee) of certificates, duly endorsed for transfer, evidencing the Tejas Units purchased and (ii) payment of the purchase price described in Section 3.3(a) by Enterprise Partners (or its designee) to Tejas Energy by wire transfer of immediately available funds to an account designated by Tejas Energy at least five Business Days prior to such transfer and assignment.

Any proposed Disposition of any Tejas Units with respect to which a Tejas' Notice of Disposition shall have been given and as to which the rights to acquire such Tejas Units shall not have been exercised in full as herein provided may be completed at any time within, but not after, 90 days after the expiration of the 30-day period during which Enterprise Partners (or its designee) may exercise the right to acquire such Tejas Units. If a Disposition is not completed within said 90-day period, Tejas' Notice of Disposition theretofore given shall in all respects be a nullity and shall be treated as though it never had been given. If such Disposition is not carried out on the same material terms set forth in Tejas' Notice of Disposition in respect thereto, such Disposition shall be of no force, effect or validity for any purpose whatsoever.

Enterprise Partners (or its designee) shall have the right and option to purchase all of the Tejas Units that Tejas Energy desires to Dispose of pursuant to such Public Offering, exercisable in the manner and on the terms hereinafter set forth.

In the event that Enterprise Partners desires to issue or Dispose of Enterprise Securities other than in a transaction referred to in Section 3.5(f), Tejas Energy (or a Permitted Affiliate designated by Tejas Energy) shall have the right and option to purchase its pro rata share (based on the aggregate ownership of Tejas Units and Article IV Units of Tejas Energy or its Permitted Affiliates) of all of the Enterprise Securities that Enterprise Partners desires to issue or Dispose of, exercisable in the manner and on the terms hereinafter set forth (such pro rata share being calculated by multiplying the number of such Enterprise Securities being issued or Disposed of by a fraction equal to the result of dividing (i) the aggregate number of Tejas Units and Article IV Units then owned by Tejas Energy or its Affiliates by (ii) the total number of Enterprise Securities outstanding on a fully diluted basis without taking into account the newly issued Enterprise Securities, if any); provided, however, that there shall be no obligation of Enterprise Partners to issue or Dispose of such Enterprise Securities to Tejas Energy (or a Permitted Affiliate designated by Tejas Energy) unless all of the Enterprise Securities that are subject to the option to purchase described in this Section 3.5 are (subject to the provisions of subsection (c) below) purchased at the same time and subject to the same terms as the other Enterprise Securities being issued or Disposed of. The total purchase price for any Enterprise Securities purchased pursuant to the exercise of any option granted by this Section 3.5 shall be equal to the number of Enterprise Securities so purchased times the Section 3.5 Price Per Unit. Prior to the issuance or Disposition of any Enterprise Securities, Enterprise Partners shall give written notice "Enterprise Partners' Notice of Disposition" to Tejas Energy setting forth: -13- C:\My Documents\Uhragt.wpd EXECUTION COPY

a description of the Enterprise Securities being offered including detail as to the terms and rights applicable thereto; the number of Enterprise Securities that Enterprise Partners desires to issue or Dispose of; the bona fide cash price, if any (or the estimated value of noncash consideration, which estimate shall not be binding upon Tejas Energy), to be received or estimated to be received in connection with such issuance or Disposition of such Enterprise Securities; and the terms upon which such issuance or Disposition is to be made and the name of the Person or Persons to whom such Disposition is to be made. Upon receipt by Tejas Energy of any such Enterprise Partners' Notice of Disposition, Tejas Energy (or a Permitted Affiliate designated by Tejas Energy) may exercise its purchase right as to the Enterprise Securities that it is entitled to purchase pursuant to Section 3.5(a) for a period of 30 days commencing with the date Enterprise Partners' Notice of Disposition was received by Tejas Energy. Such right to purchase may be exercised by Tejas Energy (or a Permitted Affiliate designated by Tejas Energy) by giving notice to Enterprise Partners that Tejas Energy has elected to acquire such Enterprise Securities. The purchase and sale contemplated by the exercise by Tejas Energy (or a Permitted Affiliate designated by Tejas Energy) of such purchase right shall be completed at a closing that shall occur within twenty days after the written notice by Tejas Energy electing to exercise the Section 3.5 purchase right or, if later, simultaneously with the closing of the offering that triggered the Section 3.5 purchase right (or, if later and if Section 3.5(d)(ii) applies, within 15 Business Days after the determination of the Designated Purchase Price in accordance with Section 3.1), by (i) the transfer and assignment by Enterprise Partners to Tejas Energy of certificates evidencing the Enterprise Securities purchased and (ii) payment of the purchase price described in Section 3.5(a) by Tejas Energy to Enterprise Partners by wire transfer of immediately available funds to an account designated by Enterprise Partners at least five Business Days prior to such transfer and assignment. Notwithstanding any other provision of this Section 3.5, if Section 3.5(d)(ii) applies and the Designated Purchase Price as determined pursuant to Section 3.1(ii) exceeds the estimated value of noncash consideration specified by Enterprise Partners in Enterprise Partners' Notice of Disposition by more than 10%, then at any time within five Business Days after such determination Tejas Energy shall have the right to notify Enterprise Partners that it is electing to cancel its exercise of such purchase right, and in the case of any such cancellation, the 90-day period referred to in Section 3.5(e) shall commence with the date of such cancellation. The "Section 3.5 Price Per Unit" shall be: the bona fide cash price specified in Enterprise Partners' Notice of Disposition, provided that the price per unit is payable solely in cash or cash equivalent; or -14- C:\My Documents\Uhragt.wpd EXECUTION COPY

if, and to the extent the price per unit is payable otherwise than as specified in Section 3.5(d)(i), then the price per unit shall be the Designated Purchase Price. Any proposed Disposition of any Enterprise Securities with respect to which an Enterprise Partners' Notice of Disposition shall have been given and as to which the right to acquire such Enterprise Securities shall not have been exercised in full as herein provided may be completed at any time within, but not after, 90 days after the expiration of the 30-day period during which Tejas Energy may exercise the right to acquire such Enterprise Securities. If a Disposition is not completed within said 90-day period, Enterprise Partners' Notice of Disposition theretofore given shall in all respects be a nullity and shall be treated as though it never had been given. If such Disposition is not carried out on the same material terms set forth in Enterprise Partners' Notice of Disposition in respect thereto such Disposition shall be of no force, effect or validity for any purpose whatsoever. The rights granted in this Section 3.5 shall not be applicable to (i) the sale of Common Units effected pursuant to a Public Offering, (ii) the issuance of Common Units or Enterprise Securities convertible into Common Units to employees of EPCO, Enterprise Partners, Enterprise GP or any of their respective Subsidiaries under employee incentive compensation programs approved or existing at or prior to the Closing Date, (iii) Common Units or Enterprise Securities convertible into Common Units issued to purchase assets or businesses from third Persons in bona fide, arm's length transactions and (iv) the issuance of Enterprise Securities upon conversion of other Enterprise Securities existing on the date hereof or issued in accordance with the terms of Section 2.2(b)(vii). Section Enterprise Change of Control. In the event of an Enterprise Change of Control (as defined in Section 3.6(d)), Enterprise Partners will provide written notice to Tejas Energy of such an Enterprise Change of Control. In the event of an Enterprise Change of Control, Tejas Energy (or a Permitted Affiliate designated by Tejas Energy) shall have the right and option to purchase all of the Common Units and Subordinated Units and other Partnership Securities in Enterprise Partners owned by EPCO, EPC II and their respective Affiliates and, to the extent practicable, all Partnership Securities owned by the new control group. The total purchase price for any such securities purchased pursuant to the exercise of any option created by this Section 3.6 shall be equal to the number of units so purchased times the Designated Purchase Price. Upon receipt by Tejas Energy of written notice from Enterprise Partners of an Enterprise Change of Control or (if later) the date upon which Tejas Energy becomes aware of the Enterprise Change of Control, Tejas Energy (or a Permitted Affiliate designated by Tejas Energy) may exercise its purchase right to acquire all (but not less than all) of the units by providing written notice to Enterprise Partners at any time within 30 days thereafter. The purchase and sale contemplated by the exercise by Tejas Energy of such purchase right shall be completed at a closing -15- C:\My Documents\Uhragt.wpd EXECUTION COPY

that shall occur before the later of (i) 30 days after the written notice by Tejas Energy electing to exercise such purchase right and (ii) 15 Business Days after the determination of the Designated Purchase Price in accordance with Section 3.1, by (A) the transfer and assignment by the sellers to Tejas Energy of certificates, duly endorsed for transfer, evidencing the Partnership Securities purchased and (ii) payment of the purchase price described in Section 3.6(b) by Tejas Energy to the sellers by wire transfer of immediately available funds to the accounts designated by the sellers at least five Business Days prior to such transfer and assignment, provided that, notwithstanding any other provision of this Agreement, if the Designated Purchase Price is determined pursuant to Section 3.1(ii), then at any time within 5 Business Days after such determination Tejas Energy shall have the right to notify Enterprise Partners that it is electing to cancel its exercise of such purchase right. For purposes of this Section 3.6, the term "Enterprise Change of Control" shall mean an event or series of related events that result in (or entering into a definitive agreement the consummation of which would result in (provided that, in the case of such an agreement, Tejas Energy's rights under this Section 3.6 shall be contingent upon the occurrence of the following)) Enterprise Partners or EPC II (only if EPC II is a member of Enterprise GP) being controlled, directly or indirectly, by someone other than Dan Duncan, his wife and/or his heirs, devisees and/or legatees (and/or trusts for any of their respective benefit). If Tejas Energy exercises its purchase option and right under this Section 3.6, then EPCO shall, upon reasonable request of Tejas Energy, transfer any of its employees primarily involved in the business of Enterprise Partners and its Subsidiaries to Enterprise GP, Enterprise Partners or any designated Subsidiary; provided that, EPCO does not guarantee that any such employee will accept such transfer. EPCO shall bear the reasonable costs necessary for such transfer. ARTICLE MAKE WHOLE Section Make Whole. If (i) Tejas Energy sells to non-Affiliates in a bona fide arm's- length transaction any of the Common Units received upon conversion of the Special Units, (ii) such sale either (A) is a block sale (as "block" is defined under Rule 10b-18 of the Securities Exchange Act of 1934, as amended), (B) together with sales by Tejas Energy of other Common Units received upon conversion of the Special Units during the three months preceding such sale, either (x) includes a number of Common Units not exceeding the average weekly trading volume requirement set forth in Rule 144(e)(1)(ii) of the Securities Act or (y) includes a number of Common Units not exceeding 205,000, or (C) is part of a firmly underwritten offering of Common Units for cash (the restrictions set forth in (A), (B) and (C) are referred to herein as the "Manner of Sale Restrictions"), (iii) the sales price per Common Unit of such sale (the "Sales Price") is less than $18 (appropriately Adjusted) and (iv) such sale occurs within one year following the Conversion Date for such Common Units (as such period may be extended pursuant to the provisions of this Section 4.1), then Enterprise Partners -16- C:\My Documents\Uhragt.wpd EXECUTION COPY

will at its option either issue additional registered Common Units to Tejas Energy, make a cash payment to Tejas Energy or effect a combination of Common Units and cash payment as follows: Enterprise Partners may issue to Tejas Energy additional Common Units having an aggregate value (based on the Closing Price for Common Units on the Business Day immediately preceding the date of issuance) in an amount equal to (i) the number of Common Units so sold by Tejas Energy multiplied by (ii) (A) $18 (as appropriately Adjusted) minus (B) the Sales Price; Enterprise Partners may pay to Tejas Energy an amount of cash in immediately available funds equal to (i) the number of Common Units so sold by Tejas Energy multiplied by (ii) (A) $18 (appropriately Adjusted) minus (B) the Sales Price; or Any combination of the foregoing. Notwithstanding the requirements of clause (iv) of the foregoing, (i) if Tejas Energy requests in writing that Enterprise Partners waive the Manner of Sale Restrictions in connection with a proposed sale by Tejas Energy of Common Units received upon conversion of Special Units and Enterprise Partners declines to waive the Manner of Sale Restrictions, then the one-year period following the applicable Conversion Date for such Common Units will be tolled for such period during which Enterprise Partners declines to waive the Manner of Sale Restrictions, (ii) in the event Tejas Energy requests a demand registration under the Registration Rights Agreement and is prevented from registering or trading Common Units as a result of black-out periods under Section 2(b)(ii) of the Registration Rights Agreement, then the one-year period following the applicable Conversion Date for such Common Units will be tolled for such black-out period, (iii) in the event Tejas Energy desires to sell Common Units in a manner not requiring registration under the Securities Act and Tejas Energy advises Enterprise Partners of such intention in writing and Enterprise Partners advises Tejas Energy in writing that there is material non-public information relating to Enterprise Partners that would prevent such a sale, then the one-year period following the applicable Conversion Date for such Common Units will be tolled for the days covered by such advice and (iv) in the event Tejas Energy desires to sell Common Units but is restricted from selling such Common Units as a result of any lock-up agreement binding on Tejas Energy pursuant to Section 4(a) of the Registration Rights Agreement, then the one-year period following the applicable Conversion Date for such Common Units will be tolled for such lock-up period. In the event Enterprise Partners is unable or fails to fulfill its obligations under this Article IV, EPCO agrees, if requested in writing by Tejas Energy to do so, to fulfill the obligations of Enterprise Partners under this Article IV on behalf of Enterprise Partners. -17- C:\My Documents\Uhragt.wpd EXECUTION COPY

ARTICLE TERM OF THIS AGREEMENT This Agreement will continue in full force and effect until the date that Tejas Energy shall Dispose of all right, title and interest in the Tejas Units and the Article IV Units to a Person other than a Permitted Affiliate, provided that in the event that Tejas Energy and the Permitted Affiliates cease to own at least 5 million of the Tejas Units and/or the Article IV Units, the rights of Tejas Energy and the Permitted Affiliates under Article II, Section 3.5 and Section 3.6 shall terminate. ARTICLE FIDUCIARY DUTIES WAIVER; BUSINESS OPPORTUNITIES Section Conduct of Affairs. In anticipation that Tejas Energy and its Affiliates may engage in the same or similar activities or lines of business and have an interest in the same areas of business opportunities as Enterprise Partners and Enterprise GP and their respective Subsidiaries, and in recognition of the difficulties attendant to any Tejas Energy Committee member ("Management Designee") who desires and endeavors fully to satisfy such Management Designee's fiduciary duties, in determining the full scope of such duties in any particular situation, the provisions of this Article VI are set forth to guide the conduct of certain affairs of Enterprise Partners and Enterprise GP and their respective Subsidiaries as they may involve the Management Designees, and to define the powers, rights and duties of the Management Designees in connection therewith. Section No Duty to Refrain from Activities. Neither Tejas Energy or its Affiliates nor any Management Designee shall have a duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as Enterprise Partners or its Subsidiaries, and to the fullest extent permitted by applicable law, neither Tejas Energy or its Affiliates nor the Management Designees shall be liable to Enterprise Partners and Enterprise GP or their respective Subsidiaries for breach of any fiduciary duty by reason of any such activities. Section No Duty to Communicate Opportunities. To the fullest extent permitted by law, if a Management Designee who is also a director, officer or employee of Tejas Energy or any of its Affiliates acquires knowledge of a potential transaction or matter that may be a business opportunity for Enterprise Partners and Enterprise GP or their respective Subsidiaries (whether such potential transaction or matter is proposed by a third Person or is conceived of by such Management Designee), such Management Designee shall be entitled to offer such business opportunity to any Person as such Management Designee deems appropriate under the circumstances in his sole discretion, and neither Tejas Energy or any of its Affiliates nor such Management Designee shall be liable to Enterprise Partners and Enterprise GP or any of their respective Subsidiaries for breach of any fiduciary duty or duty of loyalty or failure to act in (or not opposed to) the best interests of Enterprise Partners and Enterprise GP or any of their respective Subsidiaries or the derivation of any -18- C:\My Documents\Uhragt.wpd EXECUTION COPY

improper personal benefit by reason of the fact that (a) such Management Designee offered such business opportunity to any Person (rather than Enterprise Partners and Enterprise GP or any of their respective Subsidiaries) or did not communicate information regarding such business opportunity to Enterprise Partners and Enterprise GP or any of their respective Subsidiaries or (b) Tejas Energy or any of its Affiliates pursued or acquired such business opportunity for itself or directed such business opportunity to another Person or did not communicate information regarding such business opportunity to Enterprise Partners and Enterprise GP or any of their respective Subsidiaries. Section Good Faith Actions. To the fullest extent permitted by law, neither Tejas Energy nor any of its Affiliates nor any Management Designee shall be liable to Enterprise Partners and Enterprise GP or any of their respective Subsidiaries for breach of any fiduciary duty or duty of loyalty or failure to act in (or not opposed to) the best interests of Enterprise Partners and Enterprise GP or any of their respective Subsidiaries or the designation of any improper personal benefit by reason of the fact that Tejas Energy or any of its Affiliates or Management Designee in good faith takes any action or exercises any rights or gives or withholds any consent in connection with any agreement or contract between Tejas Energy or any of its Affiliates or any Management Designee on the one hand and Enterprise Partners and Enterprise GP or any of their respective Subsidiaries on the other hand. ARTICLE GOVERNING PRINCIPLES AND POLICIES Enterprise Partners and Enterprise GP hereby adopt and agree that the Code of Conduct set forth on Exhibit D (the "Code of Conduct") hereto shall, during the term of this Agreement, be the governing principles and policies for the conduct of business and operations of Enterprise Partners, Enterprise GP and their respective Subsidiaries with respect to the financial policies, audit rights, budgets, internal controls and other matters set forth in Exhibit D. The Code of Conduct may be amended, replaced or otherwise altered as provided in Section 2.2(b)(xviii). ARTICLE MISCELLANEOUS Section Injunctions.

EXHIBIT D CODE OF CONDUCT I. Introduction This Code of Conduct describes the general business principles that govern how each of the companies which make up the Enterprise group of companies conducts its affairs, as well as specific policies and procedures applicable to Enterprise Products Partners L.P, Enterprise Products Operating L.P., Enterprise Products Company, Enterprise Transportation Company and their divisions, affiliates and subsidiaries. The Enterprise group of companies has widespread activities, and each Enterprise company has wide freedom of action. However, what we all have in common is the Enterprise reputation. Upholding the Enterprise reputation is paramount. We are judged by how we act. Our reputation will be upheld if we act with honesty and integrity in all our dealings and we do what we think is right at all times within the legitimate role of business. Enterprise companies have as their core values honesty, integrity and respect for people. Enterprise companies also firmly believe in the fundamental importance of the promotion of trust, openness, teamwork and professionalism and pride in what they do. Our underlying corporate values determine our principles. These principles apply to all transactions, large or small, and describe the behavior expected of every employee in every Enterprise company in the conduct of business. In turn, the application of these principles is underpinned by procedures within each Enterprise company which are designed to make sure that its employees understand the principles and that they act in accordance with them. We recognize that it is vital that our behavior matches our intentions. All the elements of this structure--values, principles and the accompanying procedures--are necessary. Enterprise companies recognize that maintaining the trust and confidence of unitholders, employees, customers and other people with whom they do business , as well as the communities in which they work, is crucial to their continued growth and success. We intend to merit this trust by conducting ourselves according to the standards set out in our principles. These principles have served Enterprise companies well for many years. It is the responsibility of management to ensure that all employees are aware of these principles and behave in accordance with the spirit as well as the letter of this statement. II. General Business Principles 1. Objectives The objectives of Enterprise companies are to engage efficiently, responsibly and profitably in the midstream natural gas liquids, petrochemicals, transportation and other selected businesses. Enterprise companies seek a high standard of performance and aim to maintain a long-term position in their respective competitive environments. C-1

2. Responsibilities Enterprise companies recognize five areas of responsibility: a. To unitholders To protect unitholders' investment and provide an acceptable return. b. To customers To win and maintain customers by developing and providing products and services which offer value in terms of price, quality, safety and environmental impact, which are supported by the requisite technological, environmental and commercial expertise. c. To employees To respect the human rights of their employees, to provide their employees with good and safe conditions to work, and good and competitive terms and conditions of service, to promote the development and best use of human talent and equal opportunity employment, and to encourage the involvement of employees in the planning and direction of their work and in the application of these principles withing their company. It is recognized that commercial success depends on the full commitment of all employees. d. To those with whom they do business To seek mutually beneficial relationships with contractors, suppliers and in joint ventures and to promote the application of these principles in so doing. The ability to promote these principles effectively will be an important factor in the decision to enter into or remain in such relationships. e. To society To conduct business as responsible corporate members of society, to observe the laws of the countries in which they operate, to express support for fundamental human rights in line with the legitimate role of business and to give proper regard to health, safety and the environment consistent with their commitment to contribute to sustainable development. These five areas are seen as inseparable. Therefore, it is the duty of management continuously to assess the priorities and discharge its responsibilities as best in can on the bases of that assessment. 3. Economic Principles Profitability is essential to discharging the responsibilities outlined above and staying in business. It is a measure both of efficiency and of the value that customers place on Enterprise products and services. It is essential to the allocation of the necessary company resources and to support the continuing investment required to develop Enterprise businesses and meet customer needs. Without profits and a strong financial foundation, it would not be possible to fulfill these responsibilities. C-2

Enterprise companies work in a wide variety of changing social, political and economic environments, but in general they believe that the interests of the community can be served most efficiently by a market economy. Criteria for investment decisions are not exclusively economic in nature but also take into account social and environmental considerations and an appraisal of the security of the investment. 4. Business Integrity Enterprise companies insist on honesty, integrity and fairness in all aspects of their business and expect the same in their relationships with all those with whom they do business. The direct or indirect offer, payment, soliciting and acceptance of bribes in any form are unacceptable practices. Employees must avoid conflicts of interest between their private financial activities and their part in the conduct of company business. All business transactions on behalf of an Enterprise company must be reflected accurately and fairly in the accounts of the company in accordance with established procedures and be subject to audit. 5. Political Activities a. Of Companies Enterprise companies act in a socially responsible manner within the laws of the countries in which they operate in pursuit of their legitimate commercial objectives. Enterprise companies do not make payments to political parties, organizations or their representatives or take any part in party politics. However, when dealing with governments, Enterprise companies have the right and responsibility to make their position known on any matter which affects themselves, their employees, their customers or their unitholders. They also have the right to make their position known on matters affecting the community, where they have a contribution to make. b. Of Employees Where individuals wish to engage in activities in the community, including standing for election to public office, they will be given the opportunity to do so where this is appropriate in light of local circumstances. 6. Health, Safety and the Environment Consistent with their commitment to contribute to sustainable development, Enterprise companies have a systematic approach to health, safety and environmental management. To this end, Enterprise companies manage these matters as any other critical business activity. 7. The Community The most important contribution that companies can make to the social and material progress of the countries in which they operate is in performing their basic activities as effectively as possible. In addition Enterprise companies take a constructive interest in societal matters which may not be directly related to the business. Opportunities for involvement--for example, through community, educational or donations programs--will C-3

vary depending on the size of the company concerned, the nature of the local society and the scope for useful private initiatives. 8. Competition Enterprise companies support free enterprise. They seek to compete fairly and ethically and within the framework of applicable competition laws; they will not prevent others from competing freely with them. 9. Communications Enterprise companies recognize that, in view of the importance of the activities in which they are engaged and their impact on the economies of communities and individuals, open communications are essential. To this end, Enterprise companies provide relevant information about their activities to legitimately interested parties, subject to any overriding considerations of business confidentiality and cost. III. Legal and Ethical Obligations under the Code of Conduct These obligations are simply stated: - Comply fully with all applicable laws; - Foster an affirmative attitude concerning compliance with the law among those reporting to you and among your colleagues; - Demand and exhibit conduct consistent with the expectations of the communities in which we operate and necessary to maintain the good reputation of Enterprise for fair, honest and ethical conduct; and - Report any violation of our Code of Conduct or any threat to human health, safety, the environment or Enterprise assets that you have a good faith reason to believe has occurred or exists to your management or your Human Resources representative as discussed under "Reporting Compliance Issues," below. IV. Company Compliance Policies Most of the Enterprise compliance policies covering the matters discussed below are recorded in written documents generally applicable to all employees and may be obtained from your Human Resources representative. Others are adapted specifically to certain work areas or to employees dealing in the areas covered by the policy. It is the responsibility of every employee to conduct his or her job in strict compliance with such policies. Questions concerning all policies may be addressed to your immediate supervisor, your Human Resources representative or the Enterprise Law Department. Enterprise also conducts ongoing educational programs and training on certain compliance issues for employees. Because written policies and training programs cannot anticipate every possible factual situation, each employee has an obligation to seek clarification and advice whenever a question concerning compliance with our Code of Conduct arises. 1. Antitrust Laws C-4

Enterprise's Antitrust Compliance Policy and Antitrust Compliance Guide set forth Enterprise's intention to conduct operations in strict compliance with all applicable antitrust laws. The antitrust laws generally prohibit business activities that constitute unreasonable restraints of trade. This policy discusses the Sherman Act's prohibition against horizontal conduct between competitors, such a price fixing agreements. Also discussed in the policy statement are the severe criminal and civil penalties, both corporate and individual, for violations of the antitrust laws. Recommendations for avoiding inadvertent violations, including guidelines for discussions of business activities, are also included. 2. Boycott Laws Federal law prohibits persons from taking or agreeing to take certain actions in connection with any unsanctioned foreign boycott directed against any country friendly to the United States. Enterprise's Compliance with the Foreign Boycotts Title of the Export Administration Act details compliance issues and reporting requirements. 3. Conflicts of Interest Employees have a duty to avoid situations that might be adverse to Enterprise's interest or result in conflicting loyalties or interests. Enterprise's Standards of Business Conduct include discussions of prohibited involvement with suppliers, contractors, competitors or customers, prohibited gifts and entertainment and prohibited use of company information. 4. Drug and Alcohol Abuse Enterprise strives to provide employees with a workplace free from substance abuse (i.e., the illegal or illicit use of drugs and the abuse of alcohol) and a workplace where all individuals are able to perform their assigned responsibilities in a safe and productive manner. Enterprise's policies on Illegal and Unauthorized Items at Operational Facilities and in Operational Vehicles and Illegal and Unauthorized Items at Home Office and Lodge Facilities and in Company Passenger Vehicles are part of an extensive program that includes education, substance abuse identification and testing. 5. Environment Proper regard for the environment, consistent with our commitment to sustainable development, must be an essential element of all Enterprise business transactions. Every employee has a responsibility towards ensuring sound environmental performance. Enterprise's Policy on Environmental Performance sets out Enterprise's policy for full compliance with all environmental laws and regulations, including the assessment of environmental consequences before entering new ventures, activities or acquisitions, as well as fostering environmental awareness and responsibility. Corporate and individual criminal and civil liability exists for many violations of environmental laws. 6. Equal Opportunity C-5

Enterprise is fully committed to a workplace that is founded on diversity and equal opportunity and is free from discriminatory action. In support of this commitment, Enterprise's Equal Opportunity Policy clearly prohibits discrimination on the basis of race, color, religion, sex, sexual orientation, national origin, age, physical or mental handicap, status as a special disabled veteran or veteran o f the Vietnam era or citizenship of individuals legally authorized to work in the United States. Also prohibited is any form of harassment for any of these reasons. 7. Export Control All exports of commodities and technical data are regulated under federal law. Violations of export control regulations can result in serious criminal penalties to Enterprise and individuals. A summary of the export control laws and regulations is available through the Enterprise Law Department. 8. Insider Trading Federal securities laws prohibit an employee from trading in publicly held securities, including those of Enterprise Products Partners L.P., while in the possession of material confidential (non-public) information which is learned in the course of employment. Faillure to comply with these requirements may be a criminal offence in many instances. More detailed information is contained in Enterprise's Insider Trading policy and may be obtained from the Enterprise Law Department. 9. Political Contributions and Foreign Corrupt Practices Act Enterprise has adopted a policy setting forth the standard of conduct to be observed and procedures to be followed in all matters pertaining to political contributions, illegal or questionable payments and related accounting procedures. Such policy and related guidelines can be found in Enterprise's Standards of Business Conduct. The use of corporate funds or assets for any unlawful or improper purpose, including payments to governmental employees or any other person as a commercial bribe , influence payment or kickback, is prohibited. Specifically discussed are matters dealing with entertainment of or gifts to government officials and employees. As a policy, Enterprise does not make payments with corporate funds to political parties or candidates for public office. This does not mean, however, that Enterprise will not participate in public debate. Enterprise has the right and responsibility, in pursuit of its legitimate commercial objectives, to make its position known on matters affecting the community if we have expertise and can make a significant contribution to Enterprise and society. Enterprise will support Political Action Committees (PACs) in accordance with applicable law, and employees are encouraged to make personal political contributions to PACs, candidates and organizations of their choice. However, any employee who elects to make a personal political contribution must bear the entire financial burden of such a contribution. If any employee wishes to engage in political activity, including standing for election to public office, he or she will be given the opportunity to do so where this is appropriate in light of local circumstances. C-6

10. Protection of Assets Enterprise has a large variety of assets, including extremely valuable proprietary information and physical assets. Enterprise's proprietary information includes intellectual property and the confidential business data entrusted to employees in connection with their jobs. Protection of Enterprise assets and third party confidential information properly in Enterprise's possession is the personal responsibility of each employee. Further details concerning these obligations can be obtained by contacting the Enterprise Law Department. 11. Safe Workplace Environment Enterprise is fully dedicated to maintaining a workplace free of recognized health and safety hazards. In this regard Enterprise has ongoing and comprehensive programs and policies designed to achieve this policy objective and ensure full compliance with all applicable laws and regulations. See Enterprise's Policy on Occupational Safety and Health. V. Procedures for Obtaining Guidance Enterprise policies summarized above and numerous specific policies, training programs and operating procedures exist for the various jobs at Enterprise. Each employee is charged with the obligation to understand applicable policies, procedures and training made available to him or her. Seek clarification from your supervisors when necessary. Managers and supervisors have additional duty to monitor the continuing adequacy of policies, procedures and training withing their areas of responsibility and compliance with our Code of Conduct by persons reporting to them. When you have a concern or are called upon to evaluate the legal or ethical correctness of a course of action a result of your employment with Enterprise: - Seek out the appropriate policy statement and training manuals and ask your supervisor for clarification when needed. - Don't debate alone; seek the advice of legal, environmental, human resources and other administrative organizations that can be of assistance. - As a guide in making your decision, consider whether if all the facts surrounding your decision were published in the local newspaper, you would have any regrets or concerns. - Understand that Enterprise's best interests can never be served by illegal or unethical conduct and Enterprise will never condone it. Any questions concerning legal compliance that cannot be answered promptly and clearly should be referred to the Enterprise Law Department. Legal and other appropriate administrative organizations, working together, will seek to explain in a practical and readily understandable manner what is require of employees in order to comply with the law and with Enterprise's ethical requirements. Our compliance policies and training and our Code of Conduct are all aimed at avoiding violations of law and unethical conduct. Our long-term success in this area will depend on each employee's realizing C-7

Enterprise's sincere commitment to these goals, seeking advice before engaging in conduct that presents legal or ethical questions and obtaining correct and unambiguous advice. VI. Reporting Compliance Issues If an employee has a good faith reason to believe that any violation of our Code of Conduct has occurred, he or she is required to report such violation. Additionally, any good faith reason to believe that a threat to human health, safety, the environment or Enterprise assets has arisen or exists in or as the result of conduct in the workplace must be reported promptly. Reporting to your vice president, senior vice president, executive vice president or your Human Resources representative discharges this obligation. Such parties have the responsibility to see that the appropriate Enterprise management and, when compliance with law issues are raised, the appropriate representatives of the Enterprise Law Department are promptly notified. Any attempt at retaliation or intimidation against anyone reporting in good faith a suspected violation of our Code of Conduct or any condition thought to constitute a threat to human health, safety, the environment or Enterprise assets is a serious violation of our Code of Conduct. VII. Discipline Enterprise will consistently and appropriately enforce the Code of Conduct and company policies. Discipline will be determined by Enterprise senior management. Non-compliance may result in discipline up to and including discharge. In appropriate cases or when required by law, law enforcement officials will be informed of facts discovered by any investigation concerning non-compliance with the law. C-8

(e) Enterprise Partners shall have the right to terminate any proposed registration under this Section 3 at any time without any obligation to the Requesting Holders requesting inclusion in such registration under this Section 3. Section Holdback Agreement. If Enterprise Partners at any time shall register Common Units or Equity Equivalents under the Securities Act (including any registration pursuant to Section 3) for sale in an VEHOU05:142167.1 6

underwritten Public Offering, then to the extent requested by the underwriters for such offering, the Unitholders shall not sell, make any short sale of, grant any option for the purchase of, or otherwise dispose of, directly or indirectly, any Registrable Securities (other than those Registrable Securities included in such registration) without the prior written consent of Enterprise Partners, for a period designated by the managing underwriter in writing to the Unitholders, which period shall begin not more than seven days prior to the effectiveness of the registration statement pursuant to which such Public Offering shall be made (or within seven days prior to the execution of the applicable underwriting agreement in the case of an offering pursuant to Rule 415) and shall not last more than 90 days after the closing of such Public Offering or such shorter holdback period to which Enterprise Partners or other unitholders of Enterprise Partners holding at least 10% of the Common Units of Enterprise Partners (on a fully diluted basis) are subject.

Enterprise Partners shall use its Best Efforts to cause each holder of at least 10% (on a fully diluted basis) of Common Units other than Unitholders to agree not to sell publicly, make any short sale of, grant any option for the purchase of, or otherwise dispose publicly of, any Common Units or Equity Equivalents (except as part of the underwritten offering pursuant to such registration statement), without the prior written consent of the managing underwriter, for a period designated by the managing underwriter in writing to such holders, which period shall begin not more than seven days prior to the effectiveness of the registration statement pursuant to which such public offering shall be made (or within seven days prior to the execution of the applicable underwriting agreement in the case of an offering pursuant to Rule 415) and shall not last more than 90 days after the closing of the sale of units pursuant to such registration statement or such shorter holdback period to which the Unitholders are then subject. Section Preparation and Filing. If and whenever Enterprise Partners is under an obligation pursuant to the provisions of this Agreement to use its Best Efforts to effect the registration of any Registrable Securities, Enterprise Partners shall, as expeditiously as practicable: VEHOU05:142167.1 7

use its Best Efforts to cause a registration statement that registers such Registrable Securities to be filed within 45 days following the request delivered pursuant to Section 2 and to become and remain effective for a period (the "Registration Period") of 180 days (or such extended period pursuant to clause (viii) below) or until all of such Registrable Securities have been disposed of (if earlier); furnish, at least five Business Days before filing a registration statement that registers such Registrable Securities, a prospectus relating thereto or any amendments or supplements relating to such a registration statement or prospectus, to Unitholders' Counsel, copies of all such documents proposed to be filed (it being understood that such five-Business-Day period need not apply to successive drafts of the same document proposed to be filed so long as such successive drafts are supplied to Unitholders' Counsel in advance of the proposed filing by a period of time that is customary and reasonable under the circumstances); prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective at all times during the Registration Period and to comply with the provisions of the Securities Act with respect to the sale or other disposition of such Registrable Securities; notify in writing Unitholders' Counsel promptly of (A) the receipt by Enterprise Partners of any notification with respect to any comments by the Commission with respect to such registration statement or prospectus or any amendment or supplement thereto or any request by the Commission for the amending or supplementing thereof or for additional information with respect thereto, (B) the receipt by Enterprise Partners of any notification with respect to any stop order issued or threatened to be issued by the Commission suspending the effectiveness of such registration statement or prospectus or any amendment or supplement thereto or the initiation or threatening of any proceeding for that purpose and (C) the receipt by Enterprise Partners of any notification with respect to the suspension of the qualification of such Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purposes; use its Best Efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as Unitholders reasonably request and to keep such registration and qualification in effect for so long as such registration statement remains in effect and to do any and all other acts and things which may be reasonably necessary or advisable to enable Unitholders to consummate the disposition in such jurisdictions of the Registrable Securities owned by Unitholders; provided, however, that Enterprise Partners will not be required to qualify generally to do business or consent to general service of process or taxation in any jurisdiction where it would not otherwise be required to do so but for this clause (v); VEHOU05:142167.1 8

furnish, without charge, to the holders of such Registrable Securities such number of copies of such registration statement, prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents (including exhibits thereto and documents incorporated by reference therein) as such holders may reasonably request in order to facilitate the public sale or other disposition of such Registrable Securities; use its Best Efforts to cause such Registrable Securities to be registered with or approved by such other governmental agencies or authorities or self-regulatory organizations as may be necessary by virtue of the business and operations of Enterprise Partners to enable the Unitholders holding such Registrable Securities to consummate the disposition of such Registrable Securities; notify in writing holders of Registrable Securities on a timely basis at any time when a prospectus relating to such Registrable Securities is required to be delivered under the Securities Act during the Registration Period of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing and, at the request of the holders of Registrable Securities, prepare and furnish to such holders a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the offerees and purchasers of such units, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; provided, however, that the Registration Period shall be deemed to be extended by the number of days constituting the period commencing on and including the date of the giving of such notice to such seller and ending on and including the date when Enterprise Partners made available to such seller an amended or supplemented prospectus; in the case of an underwritten offering, use its Best Efforts to obtain from its independent certified public accountants "comfort" letters in customary form and at customary times and covering matters of the type customarily covered by comfort letters; in the case of an underwritten offering, (A) use its Best Efforts to obtain from its counsel an opinion or opinions in customary form to the underwriters and the holders of Registrable Securities and (B) to enter into a customary underwriting agreement and make representations and warranties to the underwriters, in form, substance and scope as are customarily made by issuers to underwriters in comparable underwritten offerings; provide a transfer agent and registrar (which may be the same entity and which may be Enterprise Partners) for such Registrable Securities; VEHOU05:142167.1 9

if required, issue to any underwriter to which the holders of Registrable Securities may sell units in such offering certificates evidencing such Registrable Securities; use its Best Efforts to list such Registrable Securities on the New York Stock Exchange or such other securities exchange on which the Common Units are traded; use all reasonable efforts to obtain the lifting at the earliest possible time of any stop order suspending the effectiveness of such registration statement or of any order preventing or suspending the use of any preliminary prospectus included therein; and use its Best Efforts to take all other steps necessary to effect the registration of such Registrable Securities contemplated hereby. Each holder of the Registrable Securities, upon receipt of any notice from Enterprise Partners of any event of the kind described in Section 5(a)(viii) hereof, shall forthwith discontinue disposition of the Registrable Securities pursuant to the registration statement covering such Registrable Securities until such holder's receipt of the copies of the supplemented or amended prospectus contemplated by Section 5(a)(viii) hereof, and, if so directed by Enterprise Partners, such holder shall deliver to Enterprise Partners all copies, other than permanent file copies then in such holder's possession, of the prospectus covering such Registrable Securities at the time of receipt of such notice. In the case of an underwritten offering pursuant to Section 2 hereof, the Requesting Unitholders shall choose the managing underwriter, provided that the managing underwriter is reasonably acceptable to Enterprise Partners. In the case of an underwritten offering pursuant to Section 3 hereof, Enterprise Partners shall choose the managing underwriter. In either case, the form of underwriting agreement shall be reasonably acceptable to Enterprise Partners. Enterprise Partners may require each seller of Registrable Securities as to which any registration is being effected hereunder to furnish to Enterprise Partners such information and complete such questionnaires regarding the seller and the distribution of such securities as Enterprise Partners may from time to time reasonably request. Section Expenses. All expenses (other than as provided in the last sentence of this Section 6) incident to the registration of Registrable Securities pursuant to Section 2 and 3 hereof, including, without limitation, the fees and expenses of the underwriters, all salaries and expenses of Enterprise Partners' officers and employees performing legal or accounting duties, the expense of any annual audit or quarterly review, the expense of any liability insurance, all registration and filing fees, the expense and fees for listing securities on one or more securities exchanges, the fees and expenses of complying with securities and blue sky laws, printing expenses, messenger and delivery expenses, fees and expenses of Enterprise Partners' counsel and accountants, and the reasonable fees and expenses of one counsel to the Unitholders not to exceed $25,000 for any registration (all such expenses being herein called "Registration Expenses"), shall be borne by Enterprise Partners; VEHOU05:142167.1 10

provided, however, that with respect to any request for registration begun pursuant to Section 2 that is subsequently withdrawn by the Requesting Unitholders, other than if such withdrawal is caused by, or made in response to, a material adverse change in the business, properties, condition, financial or otherwise, or operations of Enterprise Partners occurring on or after the date of such request, then Enterprise Partners shall not be required to pay the Registration Expenses of such registration and the Registration Expenses shall be paid by the withdrawing Unitholders pro rata based on the number of Registrable Securities to be included therein. All underwriting discounts and selling commissions applicable to the Registrable Securities and the fees and expenses of any counsel to the Unitholders not provided for in the above definition of Registration Expenses shall be borne by the holders selling such securities, in proportion to the number of securities sold by each such holder. Section Indemnification. In connection with any registration of any Registrable Securities under the Securities Act pursuant to this Agreement, Enterprise Partners shall indemnify and hold harmless, to the fullest extent permitted by law, the holders of Registrable Securities, each other Person, if any, who controls any such holder of Registrable Securities within the meaning of the Securities Act or the Exchange Act, and each of their respective directors, partners, officers and agents, against any and all losses, claims, damages or liabilities, joint or several (or actions or threatened actions in respect thereof), to which any of the foregoing Persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or threatened actions in respect thereof) arise out of or are based upon (i) an untrue statement or allegedly untrue statement of a material fact contained in the registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein or otherwise filed with the Commission, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Securities or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or, with respect to any prospectus, necessary to make the statements therein in light of the circumstances under which they were made not misleading. Enterprise Partners shall reimburse each holder of Registrable Securities and each such controlling Person for any expenses (including reasonable attorneys' fees, disbursements and expenses as incurred) reasonably incurred by any of them in connection with investigating or defending against any such loss, claim, damage, liability, action or threatened action. Notwithstanding the foregoing provisions of this Section 7, Enterprise Partners shall not be liable to any such indemnified Person in any such case to the extent that any such loss, claim, damage, liability, action or threatened action (including any reasonable legal or other fees, disbursements and expenses incurred) arises out of or is based upon an untrue statement or allegedly untrue statement or omission or alleged omission made in said registration statement, preliminary prospectus, final prospectus, amendment, supplement or document incident to registration or qualification of any Registrable Securities in reliance upon and in conformity with written information furnished to Enterprise Partners by or on behalf of a holder of Registrable Securities specifically for use in the preparation thereof. The foregoing indemnity agreement is subject to the condition that, insofar as it relates to any untrue statement, allegedly untrue statement, omission or alleged omission made in any preliminary VEHOU05:142167.1 11

prospectus but eliminated or remedied in the final prospectus (filed pursuant to Rule 424 of the Securities Act), such indemnity agreement shall not inure to the benefit of any underwriter who participates in the offering or sale of Registrable Securities or any other Person, if any, who controls such underwriter (within the meaning of the Securities Act or the Exchange Act) from whom a Person asserting any loss, claim, damage, liability or expense purchased the Registrable Securities which are the subject thereof, if a copy of such final prospectus had been made available to such underwriter and such controlling Person and such final prospectus was not delivered to such Person asserting any loss, claim, damage, liability or expense with or prior to the written confirmation of the sale of such Registrable Securities to such Person. In connection with any registration of Registrable Securities under the Securities Act pursuant to this Agreement, each holder of Registrable Securities shall severally and not jointly indemnify and hold harmless, in the same manner and to the same extent as set forth in the preceding paragraph (a) of this Section 7, Enterprise Partners, each director of Enterprise Partners, each officer of Enterprise Partners who shall sign such registration statement and each Person who controls any of the foregoing Persons (within the meaning of the Securities Act), against any losses, claims, damages or liabilities, joint or several (or actions or threatened actions in respect thereof), to which any of the foregoing Persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or threatened actions in respect thereof) arise out of or are based upon any statement or omission from such registration statement, any preliminary prospectus or final prospectus contained therein or otherwise filed with the Commission, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Securities, if such statement or omission was made in reliance upon and in conformity with written information furnished to Enterprise Partners by such holder with respect to such holder specifically for use in connection with the preparation of such registration statement, preliminary prospectus, final prospectus, amendment, supplement or document; provided, however, that the maximum amount of liability in respect of such indemnification shall be limited, in the case of each seller of Registrable Securities, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Securities effected pursuant to such registration. Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim referred to in the preceding paragraphs of this Section 7, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action. In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, (i) the indemnified party shall reasonably cooperate with the indemnifying party and its counsel in the defense of such claim, and (ii) the indemnifying party shall not be responsible for any legal or other fees, disbursements and expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided, however, that if any indemnified party shall have reasonably concluded that there may be one or more legal or equitable defenses available to such indemnified VEHOU05:142167.1 12

party which are additional to or conflict with those available to the indemnifying party, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party and such indemnifying party shall reimburse such indemnified party and any Person controlling such indemnified party for that portion of the fees, disbursements and expenses of not more than one counsel retained by the indemnified party in connection with the matters covered by the indemnity agreement provided in this Section 7 provided that no indemnifying party shall, in connection with any such suit, be liable under this subsection for the fees and expenses of more than one separate firm for all indemnified parties. No indemnifying party shall be liable for any compromise or settlement of any such action effected without its consent, such consent not to be unreasonably withheld. No indemnifying party, in the defense of any such claim or suit, shall, except with the consent of each indemnified party which shall not be unreasonably withheld, consent to any compromise or settlement which does not include as an unconditional term thereof the giving by the claimant to such indemnified party of a release from all liability in respect of such claim or suit. If the indemnification provided for in this Section 7 is unavailable to an indemnified party hereunder with respect to any loss, claim, damage, liability, action or threatened action referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability, action or threatened action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions which resulted in such loss, claim, damage, liability, action or threatened action as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether any statement or omission, including any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that the maximum amount of liability in respect of such contribution shall be limited, in the case of each seller of Registrable Securities, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Securities effected pursuant to such registration. The amount paid or payable by a party under this Section 7(d) as a result of the loss, claim, damage, liability, action or threatened action referred to above shall be deemed to include any legal or other fees, disbursements and expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation or by any method of allocation which does not take account of the equitable considerations referred to in the first and second sentences of this Section 7(d). No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. VEHOU05:142167.1 13

The provisions of this Section 7 shall be in addition to any other liability which any indemnifying party may have to any indemnified party and shall survive the termination of this Agreement. Section Underwriting Agreement. To the extent that the holders of Registrable Securities participating in any underwritten registration shall enter into an underwriting or similar agreement that contains provisions which conflict with any provision of Section 7 hereof, as between Enterprise Partners and such holders of Registrable Securities, the provisions contained in Section 7 hereof shall control. Section Information by Holder. The Unitholders shall furnish to Enterprise Partners such written information regarding the Unitholders and the distribution proposed by the Unitholders as Enterprise Partners may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Agreement. Section Exchange Act Compliance. Enterprise Partners agrees to and shall comply with all of the reporting requirements of the Exchange Act applicable to it. Upon the request of any holder of Registrable Securities, Enterprise Partners shall deliver to such holder a written statement as to whether it has complied with such requirements. Enterprise Partners shall cooperate with the Unitholders in supplying such information as may be necessary for the Unitholders to complete and file any information reporting forms presently or hereafter required by the Commission as a condition to the availability of Rule 144. Section No Conflict of Rights. Enterprise Partners shall not, after the date hereof, grant any registration rights which conflict with or impair the registration rights granted hereby. Section Termination. Except as provided in Section 7(e) hereof, this Agreement shall terminate and be of no further force or effect when there shall no longer be any Registrable Securities outstanding. Section Miscellaneous. Notices.

use reasonable efforts to cause record title to such assets (other than those assets in respect of which the General Partner determines that the expense and difficulty of conveyancing makes transfer of record title to the Partnership impracticable) to be vested in the Partnership as soon as reasonably practicable; provided, further, that, prior to the withdrawal or removal of the General Partner or as soon thereafter as practicable, the General Partner shall use reasonable efforts to effect the transfer of record title to the Partnership and, prior to any such transfer, will provide for the use of such assets in a manner satisfactory to the General Partner. All Partnership assets shall be recorded as the property of the Partnership in its books and records, irrespective of the name in which record title to such Partnership assets is held.

ARTICLE IV Certificates; Record Holders; Transfer of Partnership Interests; Redemption of Partnership Interests 4.1 Certificates. Upon the Partnership's issuance of Common Units, Subordinated Units or Class A Special Units to any Person, the Partnership shall issue one or more Certificates in the name of such Person evidencing the number of such Units being so issued.

Subject to the requirements of Section 6.7(b), the Partners holding Certificates evidencing Class A Special Units may exchange such Certificates for Certificates evidencing Common Units on or after the date on which such Class A Special Units are converted into Common Units pursuant to the terms of Section 5.12. 4.2 Mutilated, Destroyed, Lost or Stolen Certificates. (a) If any mutilated Certificate is surrendered to the Transfer Agent, the appropriate officers of the General Partner on behalf of the Partnership shall execute, and the Transfer Agent shall countersign and deliver in exchange therefor, a new Certificate evidencing the same number and type of Partnership Securities as the Certificate so surrendered. (b) The appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and the Transfer Agent shall countersign a new Certificate in place of any Certificate previously issued if the Record Holder of the Certificate: (i) makes proof by affidavit, in form and substance satisfactory to the Partnership, that a previously issued Certificate has been lost, destroyed or stolen; C:\My Documents\Mlpagt.wpd EXECUTION COPY 5

(ii) requests the issuance of a new Certificate before the Partnership has notice that the Certificate has been acquired by a purchaser for value in good faith and without notice of an adverse claim; (iii) if requested by the Partnership, delivers to the Partnership a bond, in form and substance satisfactory to the Partnership, with surety or sureties and with fixed or open penalty as the Partnership may reasonably direct, in its sole discretion, to indemnify the Partnership, the Partners, the General Partner and the Transfer Agent against any claim that may be made on account of the alleged loss, destruction or theft of the Certificate; and (iv) satisfies any other reasonable requirements imposed by the Partnership. If a Limited Partner or Assignee fails to notify the Partnership within a reasonable time after he has notice of the loss, destruction or theft of a Certificate, and a transfer of the Limited Partner Interests represented by the Certificate is registered before the Partnership, the General Partner or the Transfer Agent receives such notification, the Limited Partner or Assignee shall be precluded from making any claim against the Partnership, the General Partner or the Transfer Agent for such transfer or for a new Certificate. (c) As a condition to the issuance of any new Certificate under this Section 4.2, the Partnership may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Transfer Agent) reasonably connected therewith. 4.3 Record Holders. The Partnership shall be entitled to recognize the Record Holder as the Partner or Assignee with respect to any Partnership Interest and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Partnership Interest on the part of any other Person, regardless of whether the Partnership shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which such Partnership Interests are listed for trading. Without limiting the foregoing, when a Person (such as a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another Person in acquiring and/or holding Partnership Interests, as between the Partnership on the one hand, and such other Persons on the other, such representative Person (a) shall be the Partner or Assignee (as the case may be) of record and beneficially, (b) must execute and deliver a Transfer Application and (c) shall be bound by this Agreement and shall have the rights and obligations of a Partner or Assignee (as the case may be) hereunder and as, and to the extent, provided for herein. 4.4 Transfer Generally. (a) The term ''transfer,'' when used in this Agreement with respect to a Partnership Interest, shall be deemed to refer to a transaction by which the General Partner assigns its Partnership Interest as a general partner in the Partnership to another Person who becomes the General Partner, or by which the holder of a Limited Partner Interest assigns such Limited Partner Interest to another Person who is or becomes a Limited Partner or an Assignee, and includes a sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition by law or otherwise. (b) No Partnership Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Article IV. Any transfer or purported transfer of a Partnership Interest not made in accordance with this Article IV shall be null and void. (c) Nothing contained in this Agreement shall be construed to prevent a disposition by any member of the General Partner of any or all of the issued and outstanding member interests of the General Partner. 4.5 Registration and Transfer of Limited Partner Interests. (a) The Partnership shall keep or cause to be kept on behalf of the Partnership a register in which, subject to such reasonable regulations as it may prescribe and subject to the provisions of Section 4.5(b), the Partnership will provide C:\My Documents\Mlpagt.wpd EXECUTION COPY 6

for the registration and transfer of Limited Partner Interests. The Transfer Agent is hereby appointed registrar and transfer agent for the purpose of registering Common Units and transfers of such Common Units as herein provided. The Partnership shall not recognize transfers of Certificates evidencing Limited Partner Interests unless such transfers are effected in the manner described in this Section 4.5. Upon surrender of a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions of Section 4.5(b), the appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Common Units, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder's instructions, one or more new Certificates evidencing the same aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered. (b) Except as otherwise provided in Section 4.9, the Partnership shall not recognize any transfer of Limited Partner Interests until the Certificates evidencing such Limited Partner Interests are surrendered for registration of transfer and such Certificates are accompanied by a Transfer Application duly executed by the transferee (or the transferee's attorney-in-fact duly authorized in writing). No charge shall be imposed by the Partnership for such transfer; provided, that as a condition to the issuance of any new Certificate under this Section 4.5, the Partnership may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto. (c) Limited Partner Interests may be transferred only in the manner described in this Section 4.5. The transfer of any Limited Partner Interests and the admission of any new Limited Partner shall not constitute an amendment to this Agreement. (d) Until admitted as a Substituted Limited Partner pursuant to Section 10.2, the Record Holder of a Limited Partner Interest shall be an Assignee in respect of such Limited Partner Interest. Limited Partners may include custodians, nominees or any other individual or entity in its own or any representative capacity. (e) A transferee of a Limited Partner Interest who has completed and delivered a Transfer Application shall be deemed to have (i) requested admission as a Substituted Limited Partner, (ii) agreed to comply with and be bound by and to have executed this Agreement, (iii) represented and warranted that such transferee has the right, power and authority and, if an individual, the capacity to enter into this Agreement, (iv) granted the powers of attorney set forth in this Agreement and (v) given the consents and approvals and made the waivers contained in this Agreement. (f) The General Partner and its Affiliates shall have the right at any time to transfer its Subordinated Units, and Common Units (whether issued upon conversion of the Subordinated Units or otherwise) to one or more Persons. 4.6 Transfer of General Partner Interest. (a) Subject to Section 4.6(c) below, prior to June 30, 2008, the General Partner shall not transfer all or any part of its General Partner Interest to a Person unless such transfer (i) has been approved by the prior written consent or vote of the holders of at least a majority of the Outstanding Common Units (excluding any Common Units held by the General Partner and its Affiliates) or (ii) is of all, but not less than all, of its General Partner Interest to (A) an Affiliate of the General Partner or (B) another Person in connection with the merger or consolidation of the General Partner with or into another Person or the transfer by the General Partner of all or substantially all of its assets to another Person. (b) Subject to Section 4.6(c) below, on or after June 30, 2008, the General Partner may transfer all or any of its General Partner Interest without Unitholder approval. (c) Notwithstanding anything herein to the contrary, no transfer by the General Partner of all or any part of its General Partner Interest to another Person shall be permitted unless (i) the transferee agrees to assume the rights and duties of the General Partner under this Agreement and the Operating Partnership Agreement and to be bound by the provisions of this Agreement and the Operating Partnership Agreement, (ii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability of any Limited Partner or of any member of C:\My Documents\Mlpagt.wpd EXECUTION COPY 7

the Operating Partnership or cause the Partnership or the Operating Partnership the Operating Partnership or cause the Partnership or the Operating Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed) and (iii) such transferee also agrees to purchase all (or the appropriate portion thereof, if applicable) of the partnership interest of the General Partner as the general partner of each other Group Member. In the case of a transfer pursuant to and in compliance with this Section 4.6, the transferee or successor (as the case may be) shall, subject to compliance with the terms of Section 10.3, be admitted to the Partnership as a General Partner immediately prior to the transfer of the General Partner Interest, and the business of the Partnership shall continue without dissolution. 4.7 Restrictions on Transfers. (a) Except as provided in Section 4.7(d) below, but notwithstanding the other provisions of this Article IV, no transfer of any Partnership Interests shall be made if such transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Commission, any state securities commission or any other governmental authority with jurisdiction over such transfer, (ii) terminate the existence or qualification of the Partnership or the Operating Partnership under the laws of the jurisdiction of its formation, or (iii) cause the Partnership or the Operating Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed). (b) The General Partner may impose restrictions on the transfer of Partnership Interests if a subsequent Opinion of Counsel determines that such restrictions are necessary to avoid a significant risk of the Partnership or the Operating Partnership becoming taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes. The restrictions may be imposed by making such amendments to this Agreement as the General Partner may determine to be necessary or appropriate to impose such restrictions; provided, however, that any amendment that the General Partner believes, in the exercise of its reasonable discretion, could result in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then traded must be approved, prior to such amendment being effected, by the holders of at least a majority of the Outstanding Limited Partner Interests of such class. (c) The transfer of a Subordinated Unit that has converted into a Common Unit shall be subject to the restrictions imposed by Section 6.7(b), and the transfer of a Class A Special Unit that has been converted into a Common Unit shall be subject to the restrictions imposed by Section 6.7(b). (d) Nothing contained in this Article IV, or elsewhere in this Agreement, shall preclude the settlement of any transactions involving Partnership Interests entered into through the facilities of any National Securities Exchange on which such Partnership Interests are listed for trading. 4.8 Citizenship Certificates; Non-citizen Assignees. (a) If any Group Member is or becomes subject to any federal, state or local law or regulation that, in the reasonable determination of the General Partner, creates a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest based on the nationality, citizenship or other related status of a Limited Partner or Assignee, the General Partner may request any Limited Partner or Assignee to furnish to the General Partner, within 30 days after receipt of such request, an executed Citizenship Certification or such other information concerning his nationality, citizenship or other related status (or, if the Limited Partner or Assignee is a nominee holding for the account of another Person, the nationality, citizenship or other related status of such Person) as the General Partner may request. If a Limited Partner or Assignee fails to furnish to the General Partner within the aforementioned 30-day period such Citizenship Certification or other requested information or if upon receipt of such Citizenship Certification or other requested information the General Partner determines, with the advice of counsel, that a Limited Partner or Assignee is not an Eligible Citizen, the Partnership Interests owned by such Limited Partner or Assignee shall be subject to redemption in accordance with the provisions of Section 4.9. In addition, the General Partner may require that the status of any such Limited Partner or Assignee be changed to that of a Non-citizen Assignee and, thereupon, the General C:\My Documents\Mlpagt.wpd EXECUTION COPY 8

Partner shall be substituted for such Non-citizen Assignee as the Limited Partner in respect of his Limited Partner Interests. (b) The General Partner shall, in exercising voting rights in respect of Limited Partner Interests held by it on behalf of Non-citizen Assignees, distribute the votes in the same ratios as the votes of Partners (including without limitation the General Partner) in respect of Limited Partner Interests other than those of Non-citizen Assignees are cast, either for, against or abstaining as to the matter. (c) Upon dissolution of the Partnership, a Non-citizen Assignee shall have no right to receive a distribution in kind pursuant to Section 12.4 but shall be entitled to the cash equivalent thereof, and the Partnership shall provide cash in exchange for an assignment of the Non-citizen Assignee's share of the distribution in kind. Such payment and assignment shall be treated for Partnership purposes as a purchase by the Partnership from the Non-citizen Assignee of his Limited Partner Interest (representing his right to receive his share of such distribution in kind). (d) At any time after he can and does certify that he has become an Eligible Citizen, a Non-citizen Assignee may, upon application to the General Partner, request admission as a Substituted Limited Partner with respect to any Limited Partner Interests of such Non-citizen Assignee not redeemed pursuant to Section 4.9, and upon his admission pursuant to Section 10.2, the General Partner shall cease to be deemed to be the Limited Partner in respect of the Non-citizen Assignee's Limited Partner Interests. 4.9 Redemption of Partnership Interests of Non-citizen Assignees. (a) If at any time a Limited Partner or Assignee fails to furnish a Citizenship Certification or other information requested within the 30-day period specified in Section 4.8(a), or if upon receipt of such Citizenship Certification or other information the General Partner determines, with the advice of counsel, that a Limited Partner or Assignee is not an Eligible Citizen, the Partnership may, unless the Limited Partner or Assignee establishes to the satisfaction of the General Partner that such Limited Partner or Assignee is an Eligible Citizen or has transferred his Partnership Interests to a Person who is an Eligible Citizen and who furnishes a Citizenship Certification to the General Partner prior to the date fixed for redemption as provided below, redeem the Partnership Interest of such Limited Partner or Assignee as follows: (i) The General Partner shall, not later than the 30th day before the date fixed for redemption, give notice of redemption to the Limited Partner or Assignee, at his last address designated on the records of the Partnership or the Transfer Agent, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall specify the Redeemable Interests, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon surrender of the Certificate evidencing the Redeemable Interests and that on and after the date fixed for redemption no further allocations or distributions to which the Limited Partner or Assignee would otherwise be entitled in respect of the Redeemable Interests will accrue or be made. (ii) The aggregate redemption price for Redeemable Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Partnership Interests of the class to be so redeemed multiplied by the number of Partnership Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, in the discretion of the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 10% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date. (iii) Upon surrender by or on behalf of the Limited Partner or Assignee, at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an C:\My Documents\Mlpagt.wpd EXECUTION COPY 9

assignment duly executed in blank, the Limited Partner or Assignee or his duly authorized representative shall be entitled to receive the payment therefor. (iv) After the redemption date, Redeemable Interests shall no longer constitute issued and Outstanding Partnership Interests. (b) The provisions of this Section 4.9 shall also be applicable to Partnership Interests held by a Limited Partner or Assignee as nominee of a Person determined to be other than an Eligible Citizen. (c) Nothing in this Section 4.9 shall prevent the recipient of a notice of redemption from transferring his Partnership Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided the transferee of such Partnership Interest certifies to the satisfaction of the General Partner in a Citizenship Certification delivered in connection with the Transfer Application that he is an Eligible Citizen. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date. ARTICLE V Capital Contributions and Issuance of Partnership Interests 5.1 Prior Contributions. Prior to the date hereof, the General Partner made certain Capital Contributions to the Partnership in exchange for an interest in the Partnership and has been admitted as the General Partner of the Partnership, and EPC Partners II made certain Capital Contributions to the Partnership in exchange for an interest in the Partnership and has been admitted as a Limited Partner of the Partnership. 5.2 Continuation of General Partner and Limited Partner Interests; Initial Offering; Issuance of Class A Special Units; Contributions by the General Partner. (a) The Partnership Interest of the General Partner in the Partnership shall be continued, subject to all of the rights, privileges and duties of the General Partner under this Agreement.

(c) All other Partnership Interests that were issued prior to the date hereof and are currently Outstanding shall be continued. (d) Upon the issuance of the Class A Special Units (other than the Series 2002B Class A Special Units) and upon the issuance of any additional Limited Partner Interests by the Partnership, the General Partner shall be required to make additional Capital Contributions equal to 1/99th of any amount contributed to the Partnership in exchange for such additional Limited Partner Interests. Except as set forth in the immediately preceding sentence and Article XII, the General Partner shall not be obligated to make any additional Capital Contributions to the Partnership. 5.3 Contributions by the Underwriters. (a) On the Closing Date and pursuant to the Underwriting Agreement, each Underwriter was required to contribute to the Partnership cash in an amount equal to the Issue Price per Initial Common Unit, multiplied by the number of Common Units specified in the Underwriting Agreement to be purchased by such Underwriter at the Closing Date. In exchange for such Capital Contributions by the Underwriters, the Partnership issued Common Units to each Underwriter C:\My Documents\Mlpagt.wpd EXECUTION COPY 10

on whose behalf such Capital Contribution was made in an amount equal to the quotient obtained by dividing (i) the cash contribution to the Partnership by or on behalf of such Underwriter by (ii) the Issue Price per Initial Common Unit. (b) Upon the exercise of the Over-Allotment Option, each Underwriter was required to contribute to the Partnership cash in an amount equal to the Issue Price per Initial Common Unit, multiplied by the number of Common Units specified in the Underwriting Agreement to be purchased by such Underwriter at the Option Closing Date. In exchange for such Capital Contributions by the Underwriters, the Partnership issued Common Units to each Underwriter on whose behalf such Capital Contribution was made in an amount equal to the quotient obtained by dividing (i) the cash contributions to the Partnership by or on behalf of such Underwriter by (ii) the Issue Price per Initial Common Unit. (c) No Limited Partner Partnership Interests were issued or issuable as of or at the Closing Date other than (i) the Common Units issuable pursuant to subparagraph (a) hereof in aggregate number equal to 12,000,000, (ii) the ''Option Units'' as such term is used in the Underwriting Agreement in aggregate number up to 1,800,000 issuable upon exercise of the Over-Allotment Option pursuant to subparagraph (b) hereof, and (iii) the 33,552,915 Common Units and 21,409,870 Subordinated Units issuable to EPC Partners II pursuant to Section 5.2(b). (d) On the date hereof, Tejas shall be issued 14,500,000 Class A Special Units and be admitted as a Limited Partner of the Partnership in exchange for certain Capital Contributions described in the Tejas Contribution Agreement. If, but only if, the Year 2000 Performance Test is fully satisfied and met, Tejas will be issued an additional 3,000,000 Class A Special Units in accordance with the Year 2000 Performance Test and, if, but only if, the Year 2001 Performance Test is fully satisfied and met, Tejas will be issued an additional 3,000,000 Class A Special Units in accordance with the Year 2001 Performance Test; provided, however, that if the Year 2000 Performance Test and/or the Year 2001 Performance Test is not met, the Class A Special Units that would have been but were not issued pursuant to such tests will be issued to Tejas in accordance with the Combined Performance Test if, but only if, the Combined Performance Test is met. In no event shall the aggregate number of Class A Special Units issued upon satisfaction of the Performance Tests (collectively, the "Series 2002B Class A Special Units") exceed 6,000,000. Upon the issuance of any Series 2002 B Class A Special Units pursuant to this Section 5.3(d), the Net Agreed Value of Tejas' initial Capital Contribution shall be increased by an amount equal to the fair market value of such Series 2002B Class A Special Units discounted at a 5.42% rate to the date hereof. 5.4 Interest and Withdrawal. No interest shall be paid by the Partnership on Capital Contributions. No Partner or Assignee shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon termination of the Partnership may be considered as such by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner or Assignee shall have priority over any other Partner or Assignee either as to the return of Capital Contributions or as to profits, losses or distributions. Any such return shall be a compromise to which all Partners and Assignees agree within the meaning of 17-502(b) of the Delaware Act. 5.5 Capital Accounts. (a) The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner in its sole discretion) owning a Partnership Interest a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions made to the Partnership with respect to such Partnership Interest pursuant to this Agreement and (ii) all items of Partnership income and gain (including, without limitation, income and gain exempt from tax) computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1, and decreased by (A) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash or property made with respect to such Partnership Interest pursuant to this Agreement and (B) all items of Partnership deduction C:\My Documents\Mlpagt.wpd EXECUTION COPY 11

and loss computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1. (b) For purposes of computing the amount of any item of income, gain, loss or deduction which is to be allocated pursuant to Article VI and is to be reflected in the Partners' Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes (including, without limitation, any method of depreciation, cost recovery or amortization used for that purpose), provided, that: (i) Solely for purposes of this Section 5.5, the Partnership shall be treated as owning directly its proportionate share (as determined by the General Partner based upon the provisions of the Operating Partnership Agreement) of all property owned by the Operating Partnership. (ii) All fees and other expenses incurred by the Partnership to promote the sale of (or to sell) a Partnership Interest that can neither be deducted nor amortized under Section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and shall be allocated among the Partners pursuant to Section 6.1. (iii) Except as otherwise provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code which may be made by the Partnership and, as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for federal income tax purposes. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss. (iv) Any income, gain or loss attributable to the taxable disposition of any Partnership property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Partnership's Carrying Value with respect to such property as of such date. (v) In accordance with the requirements of Section 704(b) of the Code, any deductions for depreciation, cost recovery or amortization attributable to any Contributed Property shall be determined as if the adjusted basis of such property on the date it was acquired by the Partnership were equal to the Agreed Value of such property. Upon an adjustment pursuant to Section 5.5(d) to the Carrying Value of any Partnership property subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery or amortization attributable to such property shall be determined (A) as if the adjusted basis of such property were equal to the Carrying Value of such property immediately following such adjustment and (B) using a rate of depreciation, cost recovery or amortization derived from the same method and useful life (or, if applicable, the remaining useful life) as is applied for federal income tax purposes; provided, however, that, if the asset has a zero adjusted basis for federal income tax purposes, depreciation, cost recovery or amortization deductions shall be determined using any reasonable method that the General Partner may adopt. (vi) If the Partnership's adjusted basis in a depreciable or cost recovery property is reduced for federal income tax purposes pursuant to Section 48(q)(1) or 48(q)(3) of the Code, the amount of such reduction shall, solely for purposes hereof, be deemed to be an additional depreciation or cost recovery deduction in the year such property is placed in service and shall be allocated among the Partners pursuant to Section 6.1. Any restoration of such basis pursuant to Section 48(q)(2) of the Code shall, to the extent possible, be allocated in the same manner to the Partners to whom such deemed deduction was allocated. C:\My Documents\Mlpagt.wpd EXECUTION COPY 12

(c) (i) A transferee of a Partnership Interest shall succeed to a pro rata portion of the Capital Account of the transferor relating to the Partnership Interest so transferred. (ii) Immediately prior to the transfer of (A) a Subordinated Unit or of a Subordinated Unit that has converted into a Common Unit pursuant to Section 5.8 by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.5(c)(ii) apply) or (B) a Class A Special Unit that has converted into a Common Unit pursuant to Section 5.12, the Capital Account maintained for such Person with respect to its Subordinated Units, converted Subordinated Units or converted Class A Special Units will (x) first, be allocated to the Subordinated Units, converted Subordinated Units or converted Class A Special Units to be transferred in an amount equal to the product of (1) the number of such Subordinated Units, converted Subordinated Units or converted Class A Special Units to be transferred and (2) the Per Unit Capital Amount for a Common Unit, and (y) second, any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any Subordinated Units, converted Subordinated Units or converted Class A Special Units. Following any such allocation, the transferor's Capital Account, if any, maintained with respect to the retained Subordinated Units, converted Subordinated Units or converted Class A Special Units, if any, will have a balance equal to the amount allocated under clause (y) hereinabove, and the transferee's Capital Account established with respect to the transferred Subordinated Units, converted Subordinated Units or converted Class A Special Units will have a balance equal to the amount allocated under clause (x) hereinabove. If the transferor has not retained any Subordinated Units, converted Subordinated Units or converted Class A Special Units, any remaining balance in such Capital Account will be retained by transferor, such Capital Account interest having rights to receive distributions pursuant to Section 12.4(c) and being allocated Net Termination Losses pursuant to Section 6.1(c)(ii)(C). (d) (i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Partnership Interests for cash or Contributed Property or the conversion of the General Partner's Combined Interest to Common Units pursuant to Section 11.3(c), the Capital Account of all Partners and the Carrying Value of each Partnership property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property immediately prior to such issuance and had been allocated to the Partners at such time pursuant to Section 6.1 in the same manner as any item of gain or loss actually recognized during such period would have been allocated. In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Partnership assets (including, without limitation, cash or cash equivalents) immediately prior to the issuance of additional Partnership Interests shall be determined by the General Partner using such reasonable method of valuation as it may adopt; provided, however, that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership Interests of all Partners at such time. The General Partner shall allocate such aggregate value among the assets of the Partnership (in such manner as it determines in its discretion to be reasonable) to arrive at a fair market value for individual properties. (ii) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Capital Accounts of all Partners and the Carrying Value of all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized in a sale of such property immediately prior to such distribution for an amount equal to its fair market value, and had been allocated to the Partners, at such time, pursuant to Section 6.1 in the same manner as any item of gain or loss actually recognized during such period would have been allocated. In determining such Unrealized Gain or Unrealized Loss the aggregate cash amount and fair market value of all Partnership assets (including, without limitation, cash or cash equivalents) immediately prior to a distribution shall (A) in the case of an actual distribution which is not made pursuant to Section 12.4 or in the case of a deemed contribution and/or distribution occurring as a result of a termination of the Partnership pursuant to Section 708 of the Code, be determined and allocated in the same manner as that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined and allocated by the Liquidator using such reasonable method of valuation as it may adopt.

5.6 Issuances of Additional Partnership Securities. (a) Subject to Section 5.7, the Partnership may issue additional Partnership Securities and options, rights, warrants and appreciation rights relating to the Partnership Securities for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as shall be established by the General Partner in its sole discretion, all without the approval of any Limited Partners. (b) Each additional Partnership Security authorized to be issued by the Partnership pursuant to Section 5.6(a) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of Partnership Securities), as shall be fixed by the General Partner in the exercise of its sole discretion, including (i) the right to share Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may redeem the Partnership Security; (v) whether such Partnership Security is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Partnership Security will be issued, evidenced by certificates and assigned or transferred; and (vii) the right, if any, of each such Partnership Security to vote on Partnership matters, including matters relating to the relative rights, preferences and privileges of such Partnership Security. (c) The General Partner is hereby authorized and directed to take all actions that it deems necessary or appropriate in connection with (i) each issuance of Partnership Securities and options, rights, warrants and appreciation rights relating to Partnership Securities pursuant to this Section 5.6, (ii) the conversion of the General Partner Interest into Units pursuant to the terms of this Agreement, (iii) the admission of Additional Limited Partners and (iv) all additional issuances of Partnership Securities. The General Partner is further authorized and directed to specify the relative rights, powers and duties of the holders of the Units or other Partnership Securities being so issued. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things it deems to be necessary or advisable in connection with any future issuance of Partnership Securities or in connection with the conversion of the General Partner Interest into Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any National Securities Exchange on which the Units or other Partnership Securities are listed for trading. 5.7 Limitations on Issuance of Additional Partnership Securities. The issuance of Partnership Securities pursuant to Section 5.6 shall be subject to the following restrictions and limitations: (a) During the Subordination Period, the Partnership shall not issue (and shall not issue any options, rights, warrants or appreciation rights relating to) an aggregate of more than 22,775,000 additional Parity Units without the prior approval of the holders of a Unit Majority. The Class A Special Units issued hereunder shall be deemed to be Parity Units. In applying this limitation, there shall be excluded Common Units and other Parity Units issued (i) in connection with the exercise of the Over-Allotment Option, (ii) in accordance with Sections 5.7(b) and 5.7(c), (iii) upon conversion of Subordinated Units pursuant to Section 5.8, (iv) upon conversion of Class A Special Units pursuant to Section 5.12, (v) upon conversion of the General Partner Interest pursuant to Section 11.3(c), (vi) pursuant to the employee benefit plans of the General Partner, EPC, the Partnership or any other Group Member and (vii) in the event of a combination or subdivision of Common Units. (b) The Partnership may also issue an unlimited number of Parity Units, prior to the end of the Subordination Period and without the approval of the Unitholders if such issuance occurs (i) in connection with an Acquisition or a Capital Improvement or (ii) within 365 days of an Acquisition or a Capital Improvement where the net proceeds from such issuance are used to repay debt incurred in connection with such Acquisition or Capital Improvement, in each case where such Acquisition or Capital Improvement involves assets that, if acquired by the Partnership as of the date that is one year prior to the first day of the Quarter in which such Acquisition is to be C:\My Documents\Mlpagt.wpd EXECUTION COPY 14

consummated or such Capital Improvement is to be completed, would have resulted, on a pro forma basis, in an increase in: (A) the amount of Adjusted Operating Surplus generated by the Partnership on a per-Unit basis (for all outstanding Units) with respect to each of the four most recently completed Quarters (on a pro forma basis), as compared to (B) the actual amount of Adjusted Operating Surplus generated by the Partnership on a per-Unit basis (for all outstanding Units) (excluding Adjusted Operating Surplus attributable to the Acquisition or Capital Improvement) with respect to each of such four most recently completed Quarters. If the issuance of Units with respect to an Acquisition or Capital Improvement occurs within the first four full Quarters after the Closing Date, then Adjusted Operating Surplus as used in clauses (A) (subject to the succeeding sentence) and (B) above will be calculated (i) for each Quarter, if any, that commenced after the closing of this offering for which actual results of operations are available, based on the actual Adjusted Operating Surplus of the Partnership generated with respect to such Quarter and (ii) for each other Quarter, on a pro forma basis not inconsistent with the procedures, as applicable, set forth in Appendix D to the Registration Statement. Furthermore, the amount in clause (A) shall be determined on a pro forma basis assuming that (1) all of the Parity Units to be issued in connection with (or as a part of but within 365 days of) such Acquisition or Capital Improvement had been issued and outstanding, (2) all indebtedness for borrowed money to be incurred or assumed in connection with such Acquisition or Capital Improvement (other than any such indebtedness that is to be repaid with the proceeds of such issuance) had been incurred or assumed, in each case as of the commencement of such four-Quarter period, (3) the personnel expenses that would have been incurred by the Partnership in the operation of the acquired assets are the personnel expenses for employees to be retained by the Partnership in the operation of the acquired assets, and (4) the non-personnel costs and expenses are computed on the same basis as those incurred by the Partnership in the operation of the Partnership's business at similarly situated Partnership facilities. (c) During the Subordination Period, the Partnership shall not issue (and shall not issue any options, rights, warrants or appreciation rights relating to) additional Partnership Securities having rights to distributions or in liquidation ranking prior or senior to the Common Units, without the prior approval of the holders of a Unit Majority. (d) No fractional Units shall be issued by the Partnership. 5.8 Conversion of Subordinated Units. (a) A total of 5,352,468 of the Outstanding Subordinated Units will convert into Common Units on a one-for-one basis on the first day after the Record Date for distribution in respect of any Quarter ending on or after June 30, 2001, in respect of which: (i) distributions under Section 6.4 in respect of all Outstanding Common Units and Subordinated Units with respect to each of the three consecutive, non-overlapping four-Quarter periods immediately preceding such date equaled or exceeded the sum of the Minimum Quarterly Distribution on all of the Outstanding Common Units and Subordinated Units during such periods; (ii) the Adjusted Operating Surplus generated during each of the three consecutive, non-overlapping four- Quarter periods immediately preceding such date equaled or exceeded the sum of the Minimum Quarterly Distribution on all of the Common Units and Subordinated Units that were Outstanding during such periods on a fully diluted basis (i.e., taking into account for purposes of such determination all Outstanding Common Units, all Outstanding Subordinated Units, all Common Units and Subordinated Units issuable upon exercise of employee options that have, as of the date of determination, already vested or are scheduled to vest prior to the end of the Quarter immediately following the Quarter with respect to which such determination is made, and all Common C:\My Documents\Mlpagt.wpd EXECUTION COPY 15

Units and Subordinated Units that have as of the date of determination, been earned by but not yet issued to management of the Partnership in respect of incentive compensation), plus the related distribution on the General Partner Interest and on the general partner interest in the Operating Partnership; and (iii) the Cumulative Common Unit Arrearage on all of the Common Units is zero. (b) An additional 5,352,468 of the Outstanding Subordinated Units will convert into Common Units on a one-for- one basis on the first day after the Record Date for distribution in respect of any Quarter ending on or after June 30, 2002, in respect of which: (i) distributions under Section 6.4 in respect of all Outstanding Common Units and Subordinated Units with respect to each of the three consecutive, non-overlapping four-Quarter periods immediately preceding such date equaled or exceeded the sum of the Minimum Quarterly Distribution on all of the Outstanding Common Units and Subordinated Units during such periods; (ii) the Adjusted Operating Surplus generated during each of the three consecutive, non-overlapping four- Quarter periods immediately preceding such date equaled or exceeded the sum of the Minimum Quarterly Distribution on all of the Common Units and Subordinated Units that were outstanding during such periods on a fully diluted basis (i.e., taking into account for purposes of such determination all Outstanding Common Units, all Outstanding Subordinated Units, all Common Units and Subordinated Units issuable upon exercise of employee options that have, as of the date of determination, already vested or are scheduled to vest prior to the end of the Quarter immediately following the Quarter with respect to which such determination is made, and all Common Units and Subordinated Units that have as of the date of determination, been earned by but not yet issued to management of the Partnership in respect of incentive compensation), plus the related distribution on the General Partner Interest and on the general partner interest in the Operating Partnership; and (iii) the Cumulative Common Unit Arrearage on all of the Common Units is zero; provided, however, that the conversion of Subordinated Units pursuant to this Section 5.8(b) may not occur until at least one year following the conversion of Subordinated Units pursuant to Section 5.8(a). (c) In the event that less than all of the Outstanding Subordinated Units shall convert into Common Units pursuant to Section 5.8(a) or 5.8(b) at a time when there shall be more than one holder of Subordinated Units, then, unless all of the holders of Subordinated Units shall agree to a different allocation, the Subordinated Units that are to be converted into Common Units shall be allocated among the holders of Subordinated Units pro rata based on the number of Subordinated Units held by each such holder. (d) Any Subordinated Units that are not converted into Common Units pursuant to Sections 5.8(a) and (b) shall convert into Common Units on a one-for-one basis on the first day following the Record Date for distributions in respect of the final Quarter of the Subordination Period. (e) Notwithstanding any other provision of this Agreement, all the then Outstanding Subordinated Units will automatically convert into Common Units on a one-for-one basis as set forth in, and pursuant to the terms of, Section 11.4. (f) A Subordinated Unit that has converted into a Common Unit shall be subject to the provisions of Section 6.7(b). 5.9 Limited Preemptive Right. Except as provided in this Section 5.9, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Security, whether unissued, held in the treasury or hereafter created. The General Partner shall have the right, which it may from time to time assign in whole or in part to any of its Affiliates, to purchase Partnership Securities from the Partnership whenever, and on the same C:\My Documents\Mlpagt.wpd EXECUTION COPY 16

terms that, the Partnership issues Partnership Securities to Persons other than the General Partner and its Affiliates, to the extent necessary to maintain the Percentage Interests of the General Partner and its Affiliates equal to that which existed immediately prior to the issuance of such Partnership Securities. 5.10 Splits and Combinations. (a) Subject to Sections 5.10(d), 6.6 and 6.8 (dealing with adjustments of distribution levels), the Partnership may make a Pro Rata distribution of Partnership Securities to all Record Holders or may effect a subdivision or combination of Partnership Securities so long as, after any such event, each Partner shall have the same Percentage Interest in the Partnership as before such event, and any amounts calculated on a per Unit basis (including any Common Unit Arrearage or Cumulative Common Unit Arrearage) or stated as a number of Units (including the number of Subordinated Units that may convert prior to the end of the Subordination Period, and the number of additional Parity Units that may be issued pursuant to Section 5.7 without a Unitholder vote, and the number of Common Units into which Class A Special Units are to be converted pursuant to Section 5.12) are proportionately adjusted retroactive to the beginning of the Partnership. (b) Whenever such a distribution, subdivision or combination of Partnership Securities is declared, the General Partner shall select a Record Date as of which the distribution, subdivision or combination shall be effective and shall send notice thereof at least 20 days prior to such Record Date to each Record Holder as of a date not less than 10 days prior to the date of such notice. The General Partner also may cause a firm of independent public accountants selected by it to calculate the number of Partnership Securities to be held by each Record Holder after giving effect to such distribution, subdivision or combination. The General Partner shall be entitled to rely on any certificate provided by such firm as conclusive evidence of the accuracy of such calculation. (c) Promptly following any such distribution, subdivision or combination, the Partnership may issue Certificates to the Record Holders of Partnership Securities as of the applicable Record Date representing the new number of Partnership Securities held by such Record Holders, or the General Partner may adopt such other procedures as it may deem appropriate to reflect such changes. If any such combination results in a smaller total number of Partnership Securities Outstanding, the Partnership shall require, as a condition to the delivery to a Record Holder of such new Certificate, the surrender of any Certificate held by such Record Holder immediately prior to such Record Date. (d) The Partnership shall not issue fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units but for the provisions of Section 5.7(d) and this Section 5.10(d), each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit). 5.11 Fully Paid and Non-Assessable Nature of Limited Partner Interests. All Limited Partner Interests issued pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Section 17-607 of the Delaware Act. 5.12 Creation and Conversion of Class A Special Units. Pursuant to Section 5.6, the General Partner hereby designates and creates a special class of Units designated "Class A Special Units" and fixes the designations, preferences and relative, participating, optional or other special rights, powers and duties of the holders of the Class A Special Units as follows: (a) The Class A Special Units shall be divided into four series as set forth below, and each series of Class A Special Units shall be evidenced by a distinct Certificate issued in accordance with Section 4.1. The number of Class A Special Units comprising each series of Class A Special Units shall automatically convert into Common Units on a one-for-one basis on the date set forth opposite such number below (the "Class A Special Units Conversation Dates"): C:\My Documents\Mlpagt.wpd EXECUTION COPY 17

(i) 1,000,000 Series 2000 Class A Special Units - the first day following the Record Date for distribution in respect of the Quarter ended June 30, 2000; (ii) 5,000,000 Series 2001 Class A Special Units - the first day following the Record Date for distribution in respect of the Quarter ended June 30, 2001; (iii) 8,500,000 Series 2002 Class A Special Units plus the first 1,000,000 Series 2002B Class A Special Units, if any, issued pursuant to the second sentence of Section 5.3(d) upon satisfaction of the Performance Tests -- the first day following the Record Date for distribution in respect of the Quarter ended June 30, 2002; and (iv) other than the Series 2002B Class A Special Units converted pursuant to Section 5.12(a)(iii), the number of Series 2002B Class A Special Units, if any, issued pursuant to the second sentence of Section 5.3(d) upon satisfaction of the Performance Tests - the first day following the Record Date for distribution in respect of the Quarter ended June 30, 2003 ; provided, however, that notwithstanding the foregoing the Class A Special Units will not convert or be convertible into Common Units until after such time as the issuance of such Common Units has been approved by holders of a majority of the Units (not including for this purpose the Class A Special Units) present and entitled to vote at a meeting of Unitholders called to consider and vote upon such issuance. (b) Except as otherwise provided in this Section 5.12(b), upon conversion pursuant to Section 5.12(a), Class A Special Units to be converted shall cease to remain outstanding and shall have no rights or obligations under this Agreement. Upon a request from the General Partner, Partners holding Class A Special Units converted pursuant to Section 5.12(a) shall surrender the Certificates evidencing such Class A Special Units in exchange for Certificates issued in accordance with Section 4.1. (c) Except for distributions pursuant to Section 12.4(c) and except as otherwise expressly provided in this Agreement by reference to the Class A Special Units, the Class A Special Units shall have no voting rights, rights to distributions, rights to allocation, rights upon dissolution and liquidation or other rights with respect to the Partnership. (d) A Class A Special Unit that has converted into a Common Unit shall be subject to the provisions of Section 6.7(b). ARTICLE VI Allocations and Distributions 6.1 Allocations for Capital Account Purposes. For purposes of maintaining the Capital Accounts and in determining the rights of the Partners among themselves, the Partnership's items of income, gain, loss and deduction (computed in accordance with Section 5.5(b)) shall be allocated among the Partners in each taxable year (or portion thereof) as provided herein below. (a) Net Income. After giving effect to the special allocations set forth in Section 6.1(d), Net Income for each taxable year and all items of income, gain, loss and deduction taken into account in computing Net Income for such taxable year shall be allocated as follows: (i) First, 100% to the General Partner in an amount equal to the aggregate Net Losses allocated to the General Partner pursuant to Section 6.1(b)(iii) for all previous taxable years until the aggregate Net Income allocated to the General Partner pursuant to this Section 6.1(a)(i) for the current taxable year and all previous taxable years is equal C:\My Documents\Mlpagt.wpd EXECUTION COPY 18

to the aggregate Net Losses allocated to the General Partner pursuant to Section 6.1(b)(iii) for all previous taxable years; (ii) Second, 1% to the General Partner in an amount equal to the aggregate Net Losses allocated to the General Partner pursuant to Section 6.1(b)(ii) for all previous taxable years and 99% to Unitholders holding Common Units and Subordinated Units in accordance with their respective Percentage Interests, until the aggregate Net Income allocated to such Partners pursuant to this Section 6.1(a)(ii) for the current taxable year and all previous taxable years is equal to the aggregate Net Losses allocated to such Partners pursuant to Section 6.1(b)(ii) for all previous taxable years; and (iii) Third, the balance, if any, 100% to the General Partner and Unitholders holding Common Units and Subordinated Units in accordance with their respective Percentage Interests. (b) Net Losses. After giving effect to the special allocations set forth in Section 6.1(d), Net Losses for each taxable period and all items of income, gain, loss and deduction taken into account in computing Net Losses for such taxable period shall be allocated as follows: (i) First, 1% to the General Partner and 99% to Unitholders holding Common Units and Subordinated Units in accordance with their respective Percentage Interests, until the aggregate Net Losses allocated pursuant to this Section 6.1(b)(i) for the current taxable year and all previous taxable years is equal to the aggregate Net Income allocated to such Partners pursuant to Section 6.1(a)(iii) for all previous taxable years; provided that the Net Losses shall not be allocated pursuant to this Section 6.1(b)(i) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable year (or increase any existing deficit balance in its Adjusted Capital Account); (ii) Second, 1% to the General Partner and 99% to the Unitholders holding Common Units and Subordinated Units in accordance with their respective Percentage Interests; provided, that Net Losses shall not be allocated pursuant to this Section 6.1(b)(ii) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable year (or increase any existing deficit balance in its Adjusted Capital Account); (iii) Third, the balance, if any, 100% to the General Partner. (c) Net Termination Gains and Losses. After giving effect to the special allocations set forth in Section 6.1(d), all items of income, gain, loss and deduction taken into account in computing Net Termination Gain or Net Termination Loss for such taxable period shall be allocated in the same manner as such Net Termination Gain or Net Termination Loss is allocated hereunder. All allocations under this Section 6.1(c) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Section 6.1 and after all distributions of Available Cash provided under Sections 6.4 and 6.5 have been made; provided, however, that solely for purposes of this Section 6.1(c), Capital Accounts shall not be adjusted for distributions made pursuant to Section 12.4. (i) If a Net Termination Gain is recognized (or deemed recognized pursuant to Section 5.5(d)), such Net Termination Gain shall be allocated among the Partners in the following manner (and the Capital Accounts of the Partners shall be increased by the amount so allocated in each of the following subclauses, in the order listed, before an allocation is made pursuant to the next succeeding subclause): (A) First, to each Partner having a deficit balance in its Capital Account, in the proportion that such deficit balance bears to the total deficit balances in the Capital Accounts of all Partners, until each such Partner has been allocated Net Termination Gain equal to any such deficit balance in its Capital Account; C:\My Documents\Mlpagt.wpd EXECUTION COPY 19

(B) Second, if prior to the conversion of the last Outstanding Class A Special Unit, the Per Unit Capital Amount with respect to a Class A Special Unit is higher or lower than the Per Unit Capital Amount with respect to each Common Unit, 99% to the Unitholders holding Common Units and Class A Special Units in the manner and amount necessary to equalize, to the maximum extent possible, the Per Unit Capital Amount with respect to each Common Unit and each Class A Special Unit, and 1% to the General Partner; (C) Third, 99% to all Unitholders holding Common Units, in proportion to their relative Percentage Interests, and 1% to the General Partner until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) its Unrecovered Capital plus (2) the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Section 6.4(a)(i) or (b)(i) with respect to such Common Unit for such Quarter (the amount determined pursuant to this clause (2) is hereinafter defined as the ''Unpaid MQD''), plus (3) any then existing Cumulative Common Unit Arrearage; (D) Fourth, if such Net Termination Gain is recognized (or is deemed to be recognized) prior to the expiration of the Subordination Period, 99% to all Unitholders holding Subordinated Units, in proportion to their relative Percentage Interests, and 1% to the General Partner until the Capital Account in respect of each Subordinated Unit then Outstanding equals the sum of (1) its Unrecovered Capital, determined for the taxable year (or portion thereof) to which this allocation of gain relates, plus (2) the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Section 6.4(a)(iii) with respect to such Subordinated Unit for such Quarter; (E) Fifth, 99% to all Unitholders, in accordance with their relative Percentage Interests, and 1% to the General Partner until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) its Unrecovered Capital, plus (2) the Unpaid MQD, plus (3) any then existing Cumulative Common Unit Arrearage, plus (4) the excess of (aa) the First Target Distribution less the Minimum Quarterly Distribution for each Quarter of the Partnership's existence over (bb) the cumulative per Unit amount of any distributions of Operating Surplus that was distributed pursuant to Sections 6.4(a)(iv) and 6.4(b)(ii) (the sum of (1) plus (2) plus (3) plus (4) is hereinafter defined as the ''First Liquidation Target Amount''); (F) Sixth, 85.8673% to all Unitholders, in accordance with their relative Percentage Interests, and 14.1327% to the General Partner until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) the First Liquidation Target Amount, plus (2) the excess of (aa) the Second Target Distribution less the First Target Distribution for each Quarter of the Partnership's existence over (bb) the cumulative per Unit amount of any distributions of Operating Surplus that was distributed pursuant to Sections 6.4(a)(v) and 6.4(b)(iii) (the sum of (1) plus (2) is hereinafter defined as the ''Second Liquidation Target Amount''); (G) Seventh, 75.7653% to all Unitholders, in accordance with their relative Percentage Interests, and 24.2347% to the General Partner until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) the Second Liquidation Target Amount, plus (2) the excess of (aa) the Third Target Distribution less the Second Target Distribution for each Quarter of the Partnership's existence over (bb) the cumulative per Unit amount of any distributions of Operating Surplus that was distributed pursuant to Sections 6.4(a)(vi) and 6.4(b)(iv); and (H) Finally, any remaining amount 50.5102% to all Unitholders, in accordance with their relative Percentage Interests, and 49.4898% to the General Partner. (ii) If a Net Termination Loss is recognized (or deemed recognized pursuant to Section 5.5(d)), such Net Termination Loss shall be allocated among the Partners in the following manner (and the Capital Accounts of the C:\My Documents\Mlpagt.wpd EXECUTION COPY 20

Partners shall be decreased by the amount so allocated in each of the following subclauses, in the order listed, before an allocation is made pursuant to the next succeeding subclause): (A) First, prior to the conversion of the last Outstanding Subordinated Unit, 99% to the Unitholders holding Subordinated Units, in proportion to their relative Percentage Interests, and 1% to the General Partner until the Capital Account in respect of each Subordinated Unit then Outstanding has been reduced to zero; (B) Second, if, prior to the conversion of the last Outstanding Class A Special Unit, the Per Unit Capital Amount with respect to a Class A Special Unit is higher or lower than the Per Unit Capital Amount with respect to each Common Unit, 99% to the Unitholders holding Common Units and Class A Special Units in the manner and amount necessary to equalize, to the maximum extent possible, the Per Unit Capital Amount with respect to each Common Unit and each Class A Special Unit, and 1% to the General Partner; (C) Third, 99% to all Unitholders holding Common Units and Class A Special Units and to holders of Capital Account interests described in the last sentence of Section 5.5(c)(ii), in proportion to their relative Capital Account balances and 1% to the General Partner until the Capital Account in respect of each Common Unit and Class A Special Unit then Outstanding has been reduced to zero; and (D) Fourth, the balance, if any, 100% to the General Partner. (d) Special Allocations. Notwithstanding any other provision of this Section 6.1, the following special allocations shall be made for such taxable period: (i) Partnership Minimum Gain Chargeback. Notwithstanding any other provision of this Section 6.1, if there is a net decrease in Partnership Minimum Gain during any Partnership taxable period, each Partner shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. For purposes of this Section 6.1(d), each Partner's Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d) with respect to such taxable period (other than an allocation pursuant to Sections 6.1(d)(vi) and 6.1(d)(vii)). This Section 6.1(d)(i) is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith. (ii) Chargeback of Partner Nonrecourse Debt Minimum Gain. Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(d)(i)), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 6.1(d), each Partner's Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d), other than Section 6.1(d)(i) and other than an allocation pursuant to Sections 6.1(d)(vi) and 6.1(d)(vii), with respect to such taxable period. This Section 6.1(d)(ii) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith. (iii) Priority Allocations. (A) If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4) to any Unitholder with respect to its Units for a taxable year is greater C:\My Documents\Mlpagt.wpd EXECUTION COPY 21

(on a per Unit basis) than the amount of cash or the Net Agreed Value of property distributed to the other Unitholders with respect to their Units (on a per Unit basis), then (1) each Unitholder receiving such greater cash or property distribution shall be allocated gross income in an amount equal to the product of (aa) the amount by which the distribution (on a per Unit basis) to such Unitholder exceeds the distribution (on a per Unit basis) to the Unitholders receiving the smallest distribution and (bb) the number of Units owned by the Unitholder receiving the greater distribution; and (2) the General Partner shall be allocated gross income in an aggregate amount equal to 1/99 of the sum of the amounts allocated in clause (1) above. (B) After the application of Section 6.1(d)(iii)(A), all or any portion of the remaining items of Partnership gross income or gain for the taxable period, if any, shall be allocated 100% to the General Partner, until the aggregate amount of such items allocated to the General Partner pursuant to this paragraph 6.1(d)(iii)(B) for the current taxable year and all previous taxable years is equal to the cumulative amount of all Incentive Distributions made to the General Partner from the Closing Date to a date 45 days after the end of the current taxable year. (iv) Qualified Income Offset. In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704- 1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible unless such deficit balance is otherwise eliminated pursuant to Section 6.1(d)(i) or (ii). (v) Gross Income Allocations. In the event any Partner has a deficit balance in its Capital Account at the end of any Partnership taxable period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Partner shall be specially allocated items of Partnership gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 6.1(d)(v) shall be made only if and to the extent that such Partner would have a deficit balance in its Capital Account as adjusted after all other allocations provided for in this Section 6.1 have been tentatively made as if this Section 6.1(d)(v) were not in this Agreement. (vi) Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Partners in accordance with their respective Percentage Interests. If the General Partner determines in its good faith discretion that the Partnership's Nonrecourse Deductions must be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the other Partners, to revise the prescribed ratio to the numerically closest ratio that does satisfy such requirements. (vii) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic Risk of Loss. (viii) Nonrecourse Liabilities. For purposes of Treasury Regulation Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Partners in accordance with their respective Percentage Interests. C:\My Documents\Mlpagt.wpd EXECUTION COPY 22

(ix) Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704- 1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations. (x) Economic Uniformity. (A) With respect to any taxable period ending upon, or after, a Class A Special Unit Conversion Date, all or a portion of the remaining items of Partnership gross income or gain for such taxable period, after taking into account allocations pursuant to Section 6.1(d)(iii), shall be allocated 100% to the Partner holding Class A Special Units that have been converted to Common Units pursuant to Section 5.12, until such Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such converted Class A Special Units to an amount equal to the product of (1) the number of converted Class A Special Units held by such Partner and (2) the Per Unit Capital Amount for a Common Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying converted Class A Special Units and the Capital Accounts underlying Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of such Class A Special Units into Common Units. This allocation method for establishing such economic uniformity will only be available if the method for allocating the Capital Account maintained with respect to the Class A Special Units between the transferred and retained Class A Special Units pursuant to Section 5.5(c)(ii) does not otherwise provide such economic uniformity to the converted Class A Special Units; (B) at the election of the General Partner with respect to any taxable period ending upon, or after, the termination of the Subordination Period, all or a portion of the remaining items of Partnership gross income or gain for such taxable period, after taking into account allocations pursuant to Sections 6.1(d)(iii) and 6.1(d)(x)(A), shall be allocated 100% to each Partner holding Subordinated Units that are Outstanding as of the termination of the Subordination Period (''Final Subordinated Units'') in the proportion of the number of Final Subordinated Units held by such Partner to the total number of Final Subordinated Units then Outstanding, until each such Partner has been allocated an amount of gross income or gain which increases the Capital Account maintained with respect to such Final Subordinated Units to an amount equal to the product of (1) the number of Final Subordinated Units held by such Partner and (2) the Per Unit Capital Amount for a Common Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Final Subordinated Units and the Capital Accounts underlying Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of such Final Subordinated Units into Common Units. This allocation method for establishing such economic uniformity will only be available to the General Partner if the method for allocating the Capital Account maintained with respect to the Subordinated Units between the transferred and retained Subordinated Units pursuant to Section 5.5(c)(ii) does not otherwise provide such economic uniformity to the Final Subordinated Units. (xi) Curative Allocation. (A) Notwithstanding any other provision of this Section 6.1, other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of income, gain, loss and deduction allocated to each Partner pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Partner under the Agreed Allocations had the Required Allocations and the related Curative Allocation not otherwise been provided in this Section 6.1. Notwithstanding the preceding sentence, Required Allocations relating to (1) Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Partnership Minimum Gain and (2) Partner Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Partner Nonrecourse Debt Minimum Gain. Allocations pursuant to this Section 6.1(d)(xi)(A) shall only be made with respect to Required Allocations to the extent the General Partner reasonably determines that such C:\My Documents\Mlpagt.wpd EXECUTION COPY 23

allocations will otherwise be inconsistent with the economic agreement among the Partners. Further, allocations pursuant to this Section 6.1(d)(xi)(A) shall be deferred with respect to allocations pursuant to clauses (1) and (2) hereof to the extent the General Partner reasonably determines that such allocations are likely to be offset by subsequent Required Allocations. (B) The General Partner shall have reasonable discretion, with respect to each taxable period, to (1) apply the provisions of Section 6.1(d)(xi)(A) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 6.1(d)(xi)(A) among the Partners in a manner that is likely to minimize such economic distortions. 6.2 Allocations for Tax Purposes. (a) Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Partners in the same manner as its correlative item of ''book'' income, gain, loss or deduction is allocated pursuant to Section 6.1. (b) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for federal income tax purposes among the Partners as follows: (i) (A) In the case of a Contributed Property, such items attributable thereto shall be allocated among the Partners in the manner provided under Section 704(c) of the Code that takes into account the variation between the Agreed Value of such property and its adjusted basis at the time of contribution; and (B) any item of Residual Gain or Residual Loss attributable to a Contributed Property shall be allocated among the Partners in the same manner as its correlative item of ''book'' gain or loss is allocated pursuant to Section 6.1. (ii) (A) In the case of an Adjusted Property, such items shall (1) first, be allocated among the Partners in a manner consistent with the principles of Section 704(c) of the Code to take into account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations thereof pursuant to Section 5.5(d)(i) or 5.5(d)(ii), and (2) second, in the event such property was originally a Contributed Property, be allocated among the Partners in a manner consistent with Section 6.2(b)(i)(A); and (B) any item of Residual Gain or Residual Loss attributable to an Adjusted Property shall be allocated among the Partners in the same manner as its correlative item of ''book'' gain or loss is allocated pursuant to Section 6.1. (iii) The General Partner shall apply the principles of Treasury Regulation Section 1.704-3(d) to eliminate Book-Tax Disparities. (c) For the proper administration of the Partnership and for the preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall have sole discretion to (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (ii) make special allocations for federal income tax purposes of income (including, without limitation, gross income) or deductions; and (iii) amend the provisions of this Agreement as appropriate (A) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (B) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 6.2(c) only if such conventions, allocations or amendments would not have a material adverse effect on the Partners, the holders of any class or classes of Limited Partner Interests issued and Outstanding or the Partnership, and if such allocations are consistent with the principles of Section 704 of the Code. (d) The General Partner in its discretion may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the C:\My Documents\Mlpagt.wpd EXECUTION COPY 24

unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the Partnership's common basis of such property, despite any inconsistency of such approach with Proposed Treasury Regulation Section 1.168-2(n), Treasury Regulation Section 1.167(c)-l(a)(6) or Proposed Treasury Regulation Section 1.197-2(g)(3). If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Partnership's property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other reasonable depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Limited Partner Interests that would not have material adverse effect on the Limited Partners or the Record Holders of any class or classes of Limited Partner Interests. (e) Any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 6.2, be characterized as Recapture Income in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income. (f) All items of income, gain, loss, deduction and credit recognized by the Partnership for federal income tax purposes and allocated to the Partners in accordance with the provisions hereof shall be determined without regard to any election under Section 754 of the Code which may be made by the Partnership; provided, however, that such allocations, once made, shall be adjusted as necessary or appropriate to take into account those adjustments permitted or required by Sections 734 and 743 of the Code. (g) Each item of Partnership income, gain, loss and deduction attributable to a transferred Partnership Interest, shall for federal income tax purposes, be determined on an annual basis and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the principal National Securities Exchange on which the Common Units are then traded on the first Business Day of each month; provided, however, that such items for the period beginning on the Closing Date and ending on the last day of the month in which the Option Closing Date or the expiration of the Over-allotment Option occurs shall be allocated to the Partners as of the opening of the Nasdaq National Market on the first Business Day of the next succeeding month; and provided, further, that gain or loss on a sale or other disposition of any assets of the Partnership other than in the ordinary course of business shall be allocated to the Partners as of the opening of the Nasdaq National Market (or such other National Securities Exchange on which the Common Units are then primarily traded) on the first Business Day of the month in which such gain or loss is recognized for federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation as it determines necessary, to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder. (h) Allocations that would otherwise be made to a Limited Partner under the provisions of this Article VI shall instead be made to the beneficial owner of Limited Partner Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner in its sole discretion. 6.3 Requirement and Characterization of Distributions; Distributions to Record Holders. (a) Within 45 days following the end of each Quarter commencing with the Quarter ending on September 30, 1998, an amount equal to 100% of Available Cash with respect to such Quarter shall, subject to Section 17-607 of the Delaware Act, be distributed in accordance with this Article VI by the Partnership to the Partners as of the Record Date selected by the General Partner in its reasonable discretion. All amounts of Available Cash distributed by the Partnership on any date from any source shall be deemed to be Operating Surplus until the sum of all amounts of Available Cash theretofore distributed by the Partnership to the Partners pursuant to Section 6.4 equals the Operating Surplus from the C:\My Documents\Mlpagt.wpd EXECUTION COPY 25

Closing Date through the close of the immediately preceding Quarter. Any remaining amounts of Available Cash distributed by the Partnership on such date shall, except as otherwise provided in Section 6.5, be deemed to be ''Capital Surplus.'' All distributions required to be made under this Agreement shall be made subject to Section 17-607 of the Delaware Act. (b) Notwithstanding Section 6.3(a), in the event of the dissolution and liquidation of the Partnership, all receipts received during or after the Quarter in which the Liquidation Date occurs, other than from borrowings described in (a)(ii)(A) of the definition of Available Cash, shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 12.4. (c) The General Partner shall have the discretion to treat taxes paid by the Partnership on behalf of, or amounts withheld with respect to, all or less than all of the Partners, as a distribution of Available Cash to such Partners. (d) Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through the Transfer Agent or through any other Person or agent, only to the Record Holder of such Partnership Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction of the Partnership's liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise. 6.4 Distributions of Available Cash from Operating Surplus. (a) During Subordination Period. Available Cash with respect to any Quarter within the Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or 6.5 shall, subject to Section 17- 607 of the Delaware Act, be distributed as follows, except as otherwise required by Section 5.6(b) in respect of additional Partnership Securities issued pursuant thereto: (i) First, 99% to the Unitholders holding Common Units, Pro Rata, and 1% to the General Partner until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter; (ii) Second, 99% to the Unitholders holding Common Units, Pro Rata, and 1% to the General Partner until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage existing with respect to such Quarter; (iii) Third, 99% to the Unitholders holding Subordinated Units, Pro Rata, and 1% to the General Partner until there has been distributed in respect of each Subordinated Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter; (iv) Fourth, 99% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 1% to the General Partner until there has been distributed in respect of each such Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter; (v) Fifth, 85.8673% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 14.1327% to the General Partner until there has been distributed in respect of each such Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter; (vi) Sixth, 75.7653% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 24.2347% to the General Partner until there has been distributed in respect of each such Unit C:\My Documents\Mlpagt.wpd EXECUTION COPY 26

then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and (vii) Thereafter, 50.5102% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 49.4898% to the General Partner; provided, however, if the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with Section 6.4(a)(vii). (b) After Subordination Period. Available Cash with respect to any Quarter after the Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or 6.5, subject to Section 17-607 of the Delaware Act, shall be distributed as follows, except as otherwise required by Section 5.6(b) in respect of additional Partnership Securities issued pursuant thereto: (i) First, 99% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 1% to the General Partner until there has been distributed in respect of each such Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter; (ii) Second, 99% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 1% to the General Partner until there has been distributed in respect of each such Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter; (iii) Third, 85.8673% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 14.1327% to the General Partner until there has been distributed in respect of each such Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter; (iv) Fourth, 75.7653% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 24.2347% to the General Partner until there has been distributed in respect of each such Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and (v) Thereafter, 50.5102% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 49.4898% to the General Partner; provided, however, if the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with Section 6.4(b)(v). 6.5 Distributions of Available Cash from Capital Surplus. Available Cash that is deemed to be Capital Surplus pursuant to the provisions of Section 6.3(a) shall, subject to Section 17-607 of the Delaware Act, be distributed, unless the provisions of Section 6.3 require otherwise, 99% to all Unitholders holding Common Units and all Unitholders holding Subordinated Units, Pro Rata, and 1% to the General Partner until a hypothetical holder of a Common Unit acquired on the Closing Date has received with respect to such Common Unit, during the period since the Closing Date through such date, distributions of Available Cash that are deemed to be Capital Surplus in an aggregate amount equal to the Initial Unit Price.

of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage. Thereafter, all Available Cash shall be distributed as if it were Operating Surplus and shall be distributed in accordance with Section 6.4. 6.6 Adjustment of Minimum Quarterly Distribution and Target Distribution Levels. (a) The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution, Third Target Distribution, Common Unit Arrearages and Cumulative Common Unit Arrearages shall be proportionately adjusted in the event of any distribution, combination or subdivision (whether effected by a distribution payable in Units or otherwise) of Units or other Partnership Securities in accordance with Section 5.10. In the event of a distribution of Available Cash that is deemed to be from Capital Surplus, the then applicable Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution shall be adjusted proportionately downward to equal the product obtained by multiplying the otherwise applicable Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, as the case may be, by a fraction of which the numerator is the Unrecovered Capital of the Common Units immediately after giving effect to such distribution and of which the denominator is the Unrecovered Capital of the Common Units immediately prior to giving effect to such distribution. (b) The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution shall also be subject to adjustment pursuant to Section 6.8. 6.7 Special Provisions Relating to the Holders of Subordinated Units and Class A Special Units. (a) Except with respect to the right to vote on or approve matters requiring the vote or approval of a percentage of the holders of Outstanding Common Units and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units, the holder of a Subordinated Unit shall have all of the rights and obligations of a Unitholder holding Common Units hereunder; provided, however, that immediately upon the conversion of Subordinated Units into Common Units pursuant to Section 5.8, the Unitholder holding a Subordinated Unit so converted shall possess all of the rights and obligations of a Unitholder holding Common Units hereunder, including the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units; provided, however, that such converted Subordinated Units shall remain subject to the provisions of Sections 5.5(c)(ii), 6.1(d)(x) and 6.7(b). (b) The Unitholder holding a Subordinated Unit or a Class A Special Unit which has converted into a Common Unit pursuant to Section 5.8 or Section 5.12, respectively, shall not be issued a Common Unit Certificate pursuant to Section 4.1, and shall not be permitted to transfer its converted Subordinated Units or Class A Special Units to a Person which is not an Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that a converted Subordinated Unit or Class A Special Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.7(b), the General Partner may take whatever reasonable steps are required to provide economic uniformity to the converted Subordinated Units or Class A Special Units in preparation for a transfer of such converted Subordinated Units or Class A Special Units, including the application of Sections 5.5(c)(ii) and 6.1(d)(x); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units represented by Common Unit Certificates. (c) Immediately upon the conversion of Class A Special Units into Common Units pursuant to Section 5.12, the Unitholder holding a Class A Special Unit so converted shall possess all of the rights and obligations of a Unitholder holding Common Units hereunder, including the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units; provided, C:\My Documents\Mlpagt.wpd EXECUTION COPY 28

however, that such converted Class A Special Units shall remain subject to the provisions of Sections 5.5(c)(ii), 6.1(d)(x)(A) and 6.7(b). 6.8 Entity-Level Taxation. If legislation is enacted or the interpretation of existing language is modified by the relevant governmental authority which causes the Partnership or the Operating Partnership to be treated as an association taxable as a corporation or otherwise subjects the Partnership or the Operating Partnership to entity-level taxation for federal income tax purposes, the then applicable Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution shall be adjusted to equal the product obtained by multiplying (a) the amount thereof by (b) one minus the sum of (i) the highest marginal federal corporate (or other entity, as applicable) income tax rate of the Partnership or the Operating Partnership for the taxable year of the Partnership or the Operating Partnership in which such Quarter occurs (expressed as a percentage) plus (ii) the effective overall state and local income tax rate (expressed as a percentage) applicable to the Partnership or the Operating Partnership for the calendar year next preceding the calendar year in which such Quarter occurs (after taking into account the benefit of any deduction allowable for federal income tax purposes with respect to the payment of state and local income taxes), but only to the extent of the increase in such rates resulting from such legislation or interpretation. Such effective overall state and local income tax rate shall be determined for the taxable year next preceding the first taxable year during which the Partnership or the Operating Partnership is taxable for federal income tax purposes as an association taxable as a corporation or is otherwise subject to entity-level taxation by determining such rate as if the Partnership or the Operating Partnership had been subject to such state and local taxes during such preceding taxable year.

Except as otherwise expressly provided in this Agreement, all management powers over the business and affairs of the Partnership shall be exclusively vested in the General Partner, and no Limited Partner or Assignee shall have any management power over the business and affairs of the Partnership. In addition to the powers now or hereafter granted a general partner of a limited partnership under applicable law or which are granted to the General Partner under any other provision of this Agreement, the General Partner, subject to Section 7.3, shall have full power and authority to do all things and on such terms as it, in its sole discretion, may deem necessary or appropriate to conduct the business of the Partnership, to exercise all powers set forth in Section 2.5 and to effectuate the purposes set forth in Section 2.4, including the following: (i) the making of any expenditures, the lending or borrowing of money, the assumption or guarantee of, or other contracting for, indebtedness and other liabilities, the issuance of evidences of indebtedness, including indebtedness that is convertible into Partnership Securities, and the incurring of any other obligations; (ii) the making of tax, regulatory and other filings, or rendering of periodic or other reports to governmental or other agencies having jurisdiction over the business or assets of the Partnership; (iii) the acquisition, disposition, mortgage, pledge, encumbrance, hypothecation or exchange of any or all of the assets of the Partnership or the merger or other combination of the Partnership with or into another Person (the matters described in this clause (iii) being subject, however, to any prior approval that may be required by Section 7.3); (iv) the use of the assets of the Partnership (including cash on hand) for any purpose consistent with the terms of this Agreement, including the financing of the conduct of the operations of the Partnership Group; subject to C:\My Documents\Mlpagt.wpd EXECUTION COPY 29

(b) Notwithstanding any other provision of this Agreement, the Operating Partnership Agreement, the Delaware Act or any applicable law, rule or regulation, each of the Partners and Assignees and each other Person who may acquire an interest in Partnership Securities hereby (i) approves, ratifies and confirms the execution, delivery and performance by the parties thereto of the Operating Partnership Agreement, the Underwriting Agreement, the EPCO Agreement, and the other agreements described in or filed as a part of the Registration Statement that are related to the transactions contemplated by the Registration Statement; (ii) agrees that the General Partner (on its own or through any officer of the Partnership) is authorized to execute, deliver and perform the agreements referred to in clause (i) of this sentence and the other agreements, acts, transactions and matters described in or contemplated by the Registration Statement on behalf of the Partnership without any further act, approval or vote of the Partners or the Assignees or the other Persons who may acquire an interest in Partnership Securities; and (iii) agrees that the execution, delivery or performance by C:\My Documents\Mlpagt.wpd EXECUTION COPY 30

the General Partner, any Group Member or any Affiliate of any of them, of this Agreement or any agreement authorized or permitted under this Agreement (including the exercise by the General Partner or any Affiliate of the General Partner of the rights accorded pursuant to Article XV), shall not constitute a breach by the General Partner of any duty that the General Partner may owe the Partnership or the Limited Partners or the Assignees or any other Persons under this Agreement (or any other agreements) or of any duty stated or implied by law or equity. 7.2 Certificate of Limited Partnership. The General Partner has caused the Certificate of Limited Partnership to be filed with the Secretary of State of the State of Delaware as required by the Delaware Act and shall use all reasonable efforts to cause to be filed such other certificates or documents as may be determined by the General Partner in its sole discretion to be reasonable and necessary or appropriate for the formation, continuation, qualification and operation of a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware or any other state in which the Partnership may elect to do business or own property. To the extent that such action is determined by the General Partner in its sole discretion to be reasonable and necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 3.4(a), the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate of Limited Partnership, any qualification document or any amendment thereto to any Limited Partner. 7.3 Restrictions on General Partner's Authority. (a) The General Partner may not, without written approval of the specific act by holders of all of the Outstanding Limited Partner Interests (other than the Class A Special Units) or by other written instrument executed and delivered by holders of all of the Outstanding Limited Partner Interests (other than the Class A Special Units) subsequent to the date of this Agreement, take any action in contravention of this Agreement, including, except as otherwise provided in this Agreement, (i) committing any act that would make it impossible to carry on the ordinary business of the Partnership; (ii) possessing Partnership property, or assigning any rights in specific Partnership property, for other than a Partnership purpose; (iii) admitting a Person as a Partner; (iv) amending this Agreement in any manner; or (v) transferring its interest as general partner of the Partnership. (b) Except as provided in Articles XII and XIV, the General Partner may not sell, exchange or otherwise dispose of all or substantially all of the Partnership's assets in a single transaction or a series of related transactions or approve on behalf of the Partnership the sale, exchange or other disposition of all or substantially all of the assets of the Partnership or the Operating Partnership, without the approval of holders of a Unit Majority; provided however that this provision shall not preclude or limit the General Partner's ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the Partnership or the Operating Partnership and shall not apply to any forced sale of any or all of the assets of the Partnership or the Operating Partnership pursuant to the foreclosure of, or other realization upon, any such encumbrance. Without the approval of holders of a Unit Majority, the General Partner shall not, on behalf of the Partnership, (i) consent to any amendment to the Operating Partnership Agreement or, except as expressly permitted by Section 7.9(d), take any action permitted to be taken by a partner of the Operating Partnership, in either case, that would have a material adverse effect on the Partnership as a partner of the Operating Partnership or (ii) except as permitted under Sections 4.6, 11.1 and 11.2, elect or cause the Partnership to elect a successor general partner of the Partnership or the Operating Partnership. 7.4 Reimbursement of the General Partner.

C:\My Documents\Mlpagt.wpd EXECUTION COPY 31

(b) Subject to any applicable limitations contained in the EPCO Agreement, the General Partner shall be reimbursed on a monthly basis, or such other reasonable basis as the General Partner may determine in its sole discretion, for (i) all direct and indirect expenses it incurs or payments it makes on behalf of the Partnership (including amounts paid by the General Partner to EPC under the EPCO Agreement and including salary, bonus, incentive compensation and other amounts paid to any Person, including Affiliates of the General Partner, to perform services for the Partnership or for the General Partner in the discharge of its duties to the Partnership), and (ii) all other necessary or appropriate expenses allocable to the Partnership or otherwise reasonably incurred by the General Partner in connection with operating the Partnership's business (including expenses allocated to the General Partner by its Affiliates). The General Partner shall determine the expenses that are allocable to the Partnership in any reasonable manner determined by the General Partner in its sole discretion. Reimbursements pursuant to this Section 7.4 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7. (c) Subject to Section 5.7, the General Partner, in its sole discretion and without the approval of the Limited Partners (who shall have no right to vote in respect thereof), may propose and adopt on behalf of the Partnership employee benefit and incentive plans, employee programs and employee practices (including plans, programs and practices involving the issuance of Partnership Securities or options to purchase Partnership Securities), or cause the Partnership to issue Partnership Securities in connection with, or pursuant to, any employee benefit plan, employee program or employee practice maintained or sponsored by the General Partner or any of its Affiliates, in each case for the benefit of employees of the General Partner, any Group Member or any Affiliate, or any of them, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The Partnership agrees to issue and sell to the General Partner or any of its Affiliates any Partnership Securities that the General Partner or such Affiliate is obligated to provide to any employees pursuant to any such employee benefit plans, employee programs or employee practices. Expenses incurred by the General Partner in connection with any such plans, programs and practices (including the net cost to the General Partner or such Affiliate of Partnership Securities purchased by the General Partner or such Affiliate from the Partnership to fulfill options or awards under such plans, programs and practices) shall be reimbursed in accordance with Section 7.4(b). Any and all obligations of the General Partner under any employee benefit or incentive plans, employee programs or employee practices adopted by the General Partner as permitted by this Section 7.4(c) shall constitute obligations of the General Partner hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or 11.2 or the transferee of or successor to all of the General Partner's Partnership Interest as the General Partner in the Partnership pursuant to Section 4.6. 7.5 Outside Activities. (a) After the Closing Date, the General Partner, for so long as it is the general partner of the Partnership (i) agrees that its sole business will be to act as the general partner or managing member of the Partnership, the Operating Partnership, and any other partnership or limited liability company of which the Partnership or the Operating Partnership is, directly or indirectly, a partner or managing member and to undertake activities that are ancillary or related thereto (including being a limited partner in the partnership), (ii) shall not engage in any business or activity or incur any debts or liabilities except in connection with or incidental to (A) its performance as general partner or managing member of one or more Group Members or as described in or contemplated by the Registration Statement or (B) the acquiring, owning or disposing of debt or equity securities in any Group Member and (iii) except to the extent permitted by the EPCO Agreement, shall not, and shall cause its Affiliates not to, engage in any Restricted Activity. (b) EPC has entered into the EPCO Agreement with the Partnership and the Operating Partnership, which agreement sets forth certain restrictions on the ability of EPC and its Affiliates to engage in Restricted Activities. (c) Except as specifically restricted by Section 7.5(a) and the EPCO Agreement, each Indemnitee (other than the General Partner) shall have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or description, whether in businesses engaged in or anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and activities of any Group Member, and none C:\My Documents\Mlpagt.wpd EXECUTION COPY 32

of the same shall constitute a breach of this Agreement or any duty express or implied by law to any Group Member or any Partner or Assignee. Neither any Group Member, any Limited Partner nor any other Person shall have any rights by virtue of this Agreement, the Operating Partnership Agreement or the partnership relationship established hereby or thereby in any business ventures of any Indemnitee. (d) Subject to the terms of the EPCO Agreement and Section 7.5(a), 7.5(b), and 7.5(c) and the EPCO Agreement, but otherwise notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any Indemnitees (other than the General Partner) in accordance with the provisions of this Section 7.5 is hereby approved by the Partnership and all Partners, (ii) it shall be deemed not to be a breach of the General Partner's fiduciary duty or any other obligation of any type whatsoever of the General Partner for the Indemnitees (other than the General Partner) to engage in such business interests and activities in preference to or to the exclusion of the Partnership and (iii) the General Partner and the Indemnitees shall have no obligation to present business opportunities to the Partnership. (e) The General Partner and any of its Affiliates may acquire Partnership Securities in addition to those acquired on the Closing Date and, except as otherwise provided in this Agreement, shall be entitled to exercise all rights of the General Partner or Limited Partner, as applicable, relating to such Partnership Securities. (f) The term ''Affiliates'' when used in Sections 7.5(a) and 7.5(b) with respect to the General Partner shall not include any Group Member or any Subsidiary of the Group Member. 7.6 Loans from the General Partner; Loans or Contributions from the Partnership; Contracts with Affiliates; Certain Restrictions on the General Partner. (a) The General Partner or its Affiliates may lend to any Group Member, and any Group Member may borrow from the General Partner or any of its Affiliates, funds needed or desired by the Group Member for such periods of time and in such amounts as the General Partner may determine; provided, however, that in any such case the lending party may not charge the borrowing party interest at a rate greater than the rate that would be charged the borrowing party or impose terms less favorable to the borrowing party than would be charged or imposed on the borrowing party by unrelated lenders on comparable loans made on an arm's-length basis (without reference to the lending party's financial abilities or guarantees). The borrowing party shall reimburse the lending party for any costs (other than any additional interest costs) incurred by the lending party in connection with the borrowing of such funds. For purposes of this Section 7.6(a) and Section 7.6(b), the term ''Group Member'' shall include any Affiliate of a Group Member that is controlled by the Group Member. No Group Member may lend funds to the General Partner or any of its Affiliates (other than another Group Member). (b) The Partnership may lend or contribute to any Group Member, and any Group Member may borrow from the Partnership, funds on terms and conditions established in the sole discretion of the General Partner; provided, however, that the Partnership may not charge the Group Member interest at a rate less than the rate that would be charged to the Group Member (without reference to the General Partner's financial abilities or guarantees) by unrelated lenders on comparable loans. The foregoing authority shall be exercised by the General Partner in its sole discretion and shall not create any right or benefit in favor of any Group Member or any other Person. (c) The General Partner may itself, or may enter into an agreement, in addition to the EPCO Agreement, with any of its Affiliates to, render services to a Group Member or to the General Partner in the discharge of its duties as general partner of the Partnership. Any services rendered to a Group Member by the General Partner or any of its Affiliates shall be on terms that are fair and reasonable to the Partnership; provided, however, that the requirements of this Section 7.6(c) shall be deemed satisfied as to (i) any transaction approved by Special Approval, (ii) any transaction, the terms of which are no less favorable to the Partnership Group than those generally being provided to or available from unrelated third parties or (iii) any transaction that, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership Group), C:\My Documents\Mlpagt.wpd EXECUTION COPY 33

is equitable to the Partnership Group. The provisions of Section 7.4 shall apply to the rendering of services described in this Section 7.6(c). (d) The Partnership Group may transfer assets to joint ventures, other partnerships, corporations, limited liability companies or other business entities in which it is or thereby becomes a participant upon such terms and subject to such conditions as are consistent with this Agreement and applicable law. (e) Neither the General Partner nor any of its Affiliates shall sell, transfer or convey any property to, or purchase any property from, the Partnership, directly or indirectly, except pursuant to transactions that are fair and reasonable to the Partnership; provided, however, that the requirements of this Section 7.6(e) shall be deemed to be satisfied as to (i) the transactions effected pursuant to Sections 5.2 and 5.3 and any other transactions described in or contemplated by the Registration Statement, (ii) any transaction approved by Special Approval, (iii) any transaction, the terms of which are no less favorable to the Partnership than those generally being provided to or available from unrelated third parties, or (iv) any transaction that, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership), is equitable to the Partnership. With respect to any contribution of assets to the Partnership in exchange for Partnership Securities, the Audit and Conflicts Committee, in determining whether the appropriate number of Partnership Securities are being issued, may take into account, among other things, the fair market value of the assets, the liquidated and contingent liabilities assumed, the tax basis in the assets, the extent to which tax-only allocations to the transferor will protect the existing partners of the Partnership against a low tax basis, and such other factors as the Audit and Conflicts Committee deems relevant under the circumstances. (f) The General Partner and its Affiliates will have no obligation to permit any Group Member to use any facilities or assets of the General Partner and its Affiliates, except as may be provided in contracts entered into from time to time specifically dealing with such use, nor shall there be any obligation on the part of the General Partner or its Affiliates to enter into such contracts. (g) Without limitation of Sections 7.6(a) through 7.6(f), and notwithstanding anything to the contrary in this Agreement, the existence of the conflicts of interest described in the Registration Statement are hereby approved by all Partners. 7.7 Indemnification. (a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, all Indemnitees shall be indemnified and held harmless by the Partnership from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as a Person of the type described in clauses (a)--(d) of the definition of the term ''Indemnitee''; provided, that in each case the Indemnitee acted in good faith and in a manner that such Indemnitee reasonably believed to be in, or (in the case of a Person other than the General Partner) not opposed to, the best interests of the Partnership and, with respect to any criminal proceeding, had no reasonable cause to believe its conduct was unlawful; provided, further, no indemnification pursuant to this Section 7.7 shall be available to the General Partner with respect to its obligations incurred pursuant to the Underwriting Agreement (other than obligations incurred by the General Partner on behalf of the Partnership or the Operating Partnership). The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the Indemnitee acted in a manner contrary to that specified above. Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification. C:\My Documents\Mlpagt.wpd EXECUTION COPY 34

(b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 7.7(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Partnership of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 7.7. (c) The indemnification provided by this Section 7.7 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the holders of Outstanding Limited Partner Interests entitled to vote on such matter, as a matter of law or otherwise, both as to actions in the Indemnitee's capacity as a Person of the type described in clauses (a)--(d) of the definition of the term ''Indemnitee'', and as to actions in any other capacity (including any capacity under the Underwriting Agreement), and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee. (d) The Partnership may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of) insurance, on behalf of the General Partner, its Affiliates and such other Persons as the General Partner shall determine, against any liability that may be asserted against or expense that may be incurred by such Person in connection with the Partnership's activities or such Person's activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement. (e) For purposes of this Section 7.7, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute ''fines'' within the meaning of Section 7.7(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Partnership. (f) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification provisions set forth in this Agreement. (g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. (h) The provisions of this Section 7.7 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. (i) No amendment, modification or repeal of this Section 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the Partnership to indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 7.8 Liability of Indemnitees. (a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Partnership, the Limited Partners, the Assignees or any other Persons who have acquired interests in the Partnership Securities, for losses sustained or liabilities incurred as a result of any act or omission if such Indemnitee acted in good faith.

(b) Subject to its obligations and duties as General Partner set forth in Section 7.1(a), the General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith. (c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to the Partners, the General Partner and any other Indemnitee acting in connection with the Partnership's business or affairs shall not be liable to the Partnership or to any Partner for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or otherwise modify the duties and liabilities of an Indemnitee otherwise existing at law or in equity, are agreed by the Partners to replace such other duties and liabilities of such Indemnitee. (d) Any amendment, modification or repeal of this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability to the Partnership, the Limited Partners, the General Partner, and the Partnership's and General Partner's directors, officers and employees under this Section 7.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 7.9 Resolution of Conflicts of Interest. (a) Unless otherwise expressly provided in this Agreement or the Operating Partnership Agreement, whenever a potential conflict of interest exists or arises between the General Partner or any of its Affiliates, on the one hand, and the Partnership, the Operating Partnership, any Partner or any Assignee, on the other, any resolution or course of action by the General Partner or its Affiliates in respect of such conflict of interest shall be permitted and deemed approved by all Partners, and shall not constitute a breach of this Agreement, of the Operating Partnership Agreement, of any agreement contemplated herein or therein, or of any duty stated or implied by law or equity, if the resolution or course of action is, or by operation of this Agreement is deemed to be, fair and reasonable to the Partnership. The General Partner shall be authorized but not required in connection with its resolution of such conflict of interest to seek Special Approval of such resolution. Any conflict of interest and any resolution of such conflict of interest shall be conclusively deemed fair and reasonable to the Partnership if such conflict of interest or resolution is (i) approved by Special Approval (as long as the material facts within the actual knowledge of the officers and directors of the General Partner and EPC regarding the proposed transaction were disclosed to the Audit and Conflicts Committee at the time it gave its approval), (ii) on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or (iii) fair to the Partnership, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership). The General Partner may also adopt a resolution or course of action that has not received Special Approval. The General Partner (including the Audit and Conflicts Committee in connection with Special Approval) shall be authorized in connection with its determination of what is ''fair and reasonable'' to the Partnership and in connection with its resolution of any conflict of interest to consider (A) the relative interests of any party to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interest; (B) any customary or accepted industry practices and any customary or historical dealings with a particular Person; (C) any applicable generally accepted accounting practices or principles; and (D) such additional factors as the General Partner (including the Audit and Conflicts Committee) determines in its sole discretion to be relevant, reasonable or appropriate under the circumstances. Nothing contained in this Agreement, however, is intended to nor shall it be construed to require the General Partner (including the Audit and Conflicts Committee) to consider the interests of any Person other than the Partnership. In the absence of bad faith by the General Partner, the resolution, action or terms so made, taken or provided by the General Partner with respect to such matter shall not constitute a breach of this Agreement or any other agreement contemplated herein or a breach of any standard of care or duty imposed herein or therein or, to the extent permitted by law, under the Delaware Act or any other law, rule or regulation. C:\My Documents\Mlpagt.wpd EXECUTION COPY 36

(b) Whenever this Agreement or any other agreement contemplated hereby provides that the General Partner or any of its Affiliates is permitted or required to make a decision (i) in its ''sole discretion'' or ''discretion,'' that it deems ''necessary or appropriate'' or ''necessary or advisable'' or under a grant of similar authority or latitude, except as otherwise provided herein, the General Partner or such Affiliate shall be entitled to consider only such interests and factors as it desires and shall have no duty or obligation to give any consideration to any interest of, or factors affecting, the Partnership, the Operating Partnership, any Limited Partner or any Assignee, (ii) it may make such decision in its sole discretion (regardless of whether there is a reference to ''sole discretion'' or ''discretion'') unless another express standard is provided for, or (iii) in ''good faith'' or under another express standard, the General Partner or such Affiliate shall act under such express standard and shall not be subject to any other or different standards imposed by this Agreement, the Operating Partnership Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation. In addition, any actions taken by the General Partner or such Affiliate consistent with the standards of ''reasonable discretion'' set forth in the definitions of Available Cash or Operating Surplus shall not constitute a breach of any duty of the General Partner to the Partnership or the Limited Partners. The General Partner shall have no duty, express or implied, to sell or otherwise dispose of any asset of the Partnership Group other than in the ordinary course of business. No borrowing by any Group Member or the approval thereof by the General Partner shall be deemed to constitute a breach of any duty of the General Partner to the Partnership or the Limited Partners by reason of the fact that the purpose or effect of such borrowing is directly or indirectly to (A) enable distributions to the General Partner or its Affiliates (including in their capacities as Limited Partners) to exceed 1% of the total amount distributed to all partners or (B) hasten the expiration of the Subordination Period or the conversion of any Subordinated Units into Common Units. (c) Whenever a particular transaction, arrangement or resolution of a conflict of interest is required under this Agreement to be ''fair and reasonable'' to any Person, the fair and reasonable nature of such transaction, arrangement or resolution shall be considered in the context of all similar or related transactions. (d) The Unitholders hereby authorize the General Partner, on behalf of the Partnership as a partner or member of a Group Member, to approve of actions by the general partner or managing member of such Group Member similar to those actions permitted to be taken by the General Partner pursuant to this Section 7.9. 7.10 Other Matters Concerning the General Partner. (a) The General Partner may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties. (b) The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the opinion (including an Opinion of Counsel) of such Persons as to matters that the General Partner reasonably believes to be within such Person's professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion. (c) The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its duly authorized officers, a duly appointed attorney or attorneys-in-fact or the duly authorized officers of the Partnership. Each such attorney shall, to the extent provided by the General Partner in the power of attorney, have full power and authority to do and perform each and every act and duty that is permitted or required to be done by the General Partner hereunder. (d) Any standard of care and duty imposed by this Agreement or under the Delaware Act or any applicable law, rule or regulation shall be modified, waived or limited, to the extent permitted by law, as required to permit the General Partner to act under this Agreement or any other agreement contemplated by this Agreement and to make any decision C:\My Documents\Mlpagt.wpd EXECUTION COPY 37

pursuant to the authority prescribed in this Agreement, so long as such action is reasonably believed by the General Partner to be in, or not inconsistent with, the best interests of the Partnership. 7.11 Purchase or Sale of Partnership Securities. The General Partner may cause the Partnership to purchase or otherwise acquire Partnership Securities; provided that, except as permitted pursuant to Section 4.10, the General Partner may not cause any Group Member to purchase Subordinated Units during the Subordination Period. As long as Partnership Securities are held by any Group Member, such Partnership Securities shall not be considered Outstanding for any purpose, except as otherwise provided herein. The General Partner or any Affiliate of the General Partner may also purchase or otherwise acquire and sell or otherwise dispose of Partnership Securities for its own account, subject to the provisions of Articles IV and X. 7.12 Registration Rights of the General Partner and its Affiliates. (a) If (i) the General Partner or any Affiliate of the General Partner (including for purposes of this Section 7.12, any Person that is an Affiliate of the General Partner at the date hereof notwithstanding that it may later cease to be an Affiliate of the General Partner) holds Partnership Securities that it desires to sell and (ii) Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such holder of Partnership Securities (the ''Holder'') to dispose of the number of Partnership Securities it desires to sell at the time it desires to do so without registration under the Securities Act, then upon the request of the General Partner or any of its Affiliates, the Partnership shall file with the Commission as promptly as practicable after receiving such request, and use all reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all Partnership Securities covered by such registration statement have been sold, a registration statement under the Securities Act registering the offering and sale of the number of Partnership Securities specified by the Holder; provided, however, that the Partnership shall not be required to effect more than three registrations pursuant to this Section 7.12(a); and provided further, however, that if at the time a request pursuant to this Section 7.12 is submitted to the Partnership, EPC or its Affiliates requesting registration is an Affiliate of the General Partner and the Audit and Conflicts Committee determines in its good faith judgment that a postponement of the requested registration for up to six months would be in the best interests of the Partnership and its Partners due to a pending transaction, investigation or other event, the filing of such registration statement or the effectiveness thereof may be deferred for up to six months, but not thereafter. In connection with any registration pursuant to the immediately preceding sentence, the Partnership shall promptly prepare and file (x) such documents as may be necessary to register or qualify the securities subject to such registration under the securities laws of such states as the Holder shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such registration, and (y) such documents as may be necessary to apply for listing or to list the Partnership Securities subject to such registration on such National Securities Exchange as the Holder shall reasonably request, and do any and all other acts and things that may reasonably be necessary or advisable to enable the Holder to consummate a public sale of such Partnership Securities in such states. Except as set forth in Section 7.12(c), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder. (b) If the Partnership shall at any time propose to file a registration statement under the Securities Act for an offering of equity securities of the Partnership for cash (other than an offering relating solely to an employee benefit plan), the Partnership shall use all reasonable efforts to include such number or amount of securities held by the Holder in such registration statement as the Holder shall request. If the proposed offering pursuant to this Section 7.12(b) shall be an underwritten offering, then, in the event that the managing underwriter or managing underwriters of such offering advise the Partnership and the Holder in writing that in their opinion the inclusion of all or some of the Holder's Partnership Securities would adversely and materially affect the success of the offering, the Partnership shall include in such offering only that number or amount, if any, of securities held by the Holder which, in the opinion of the managing underwriter or managing underwriters, will not so adversely and materially affect the offering. Except as set C:\My Documents\Mlpagt.wpd EXECUTION COPY 38

forth in Section 7.12(c), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder. (c) If underwriters are engaged in connection with any registration referred to in this Section 7.12, the Partnership shall provide indemnification, representations, covenants, opinions and other assurance to the underwriters in form and substance reasonably satisfactory to such underwriters. Further, in addition to and not in limitation of the Partnership's obligation under Section 7.7, the Partnership shall, to the fullest extent permitted by law, indemnify and hold harmless the Holder, its officers, directors and each Person who controls the Holder (within the meaning of the Securities Act) and any agent thereof (collectively, ''Indemnified Persons'') against any losses, claims, demands, actions, causes of action, assessments, damages, liabilities (joint or several), costs and expenses (including interest, penalties and reasonable attorneys' fees and disbursements), resulting to, imposed upon, or incurred by the Indemnified Persons, directly or indirectly, under the Securities Act or otherwise (hereinafter referred to in this Section 7.12(c) as a ''claim'' and in the plural as ''claims'') based upon, arising out of or resulting from any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which any Partnership Securities were registered under the Securities Act or any state securities or Blue Sky laws, in any preliminary prospectus (if used prior to the effective date of such registration statement), or in any summary or final prospectus or in any amendment or supplement thereto (if used during the period the Partnership is required to keep the registration statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein not misleading; provided, however, that the Partnership shall not be liable to any Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, such preliminary, summary or final prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Indemnified Person specifically for use in the preparation thereof. (d) The provisions of Section 7.12(a) and 7.12(b) shall continue to be applicable with respect to the General Partner (and any of the General Partner's Affiliates) after it ceases to be a Partner of the Partnership, during a period of two years subsequent to the effective date of such cessation and for so long thereafter as is required for the Holder to sell all of the Partnership Securities with respect to which it has requested during such two-year period inclusion in a registration statement otherwise filed or that a registration statement be filed; provided, however, that the Partnership shall not be required to file successive registration statements covering the same Partnership Securities for which registration was demanded during such two-year period. The provisions of Section 7.12(c) shall continue in effect thereafter. (e) Any request to register Partnership Securities pursuant to this Section 7.12 shall (i) specify the Partnership Securities intended to be offered and sold by the Person making the request, (ii) express such Person's present intent to offer such shares for distribution, (iii) describe the nature or method of the proposed offer and sale of Partnership Securities, and (iv) contain the undertaking of such Person to provide all such information and materials and take all action as may be required in order to permit the Partnership to comply with all applicable requirements in connection with the registration of such Partnership Securities. 7.13 Reliance by Third Parties. Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner and any officer of the General Partner authorized by the General Partner to act on behalf of and in the name of the Partnership has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any authorized contracts on behalf of the Partnership, and such Person shall be entitled to deal with the General Partner or any such officer as if it were the Partnership's sole party in interest, both legally and beneficially. Each Limited Partner hereby waives any and all defenses or other remedies that may be available against such Person to contest, negate or disaffirm any action of the General Partner or C:\My Documents\Mlpagt.wpd EXECUTION COPY 39

any such officer in connection with any such dealing. In no event shall any Person dealing with the General Partner or any such officer or its representatives be obligated to ascertain that the terms of the Agreement have been complied with or to inquire into the necessity or expedience of any act or action of the General Partner or any such officer or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or any such officer or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (i) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (ii) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (iii) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Partnership. ARTICLE VIII Books, Records, Accounting and Reports 8.1 Records and Accounting. The General Partner shall keep or cause to be kept at the principal office of the Partnership appropriate books and records with respect to the Partnership's business, including all books and records necessary to provide to the Limited Partners any information required to be provided pursuant to Section 3.4(a). Any books and records maintained by or on behalf of the Partnership in the regular course of its business, including the record of the Record Holders and Assignees of Units or other Partnership Securities, books of account and records of Partnership proceedings, may be kept on, or be in the form of, computer disks, hard drives, punch cards, magnetic tape, photographs, micrographics or any other information storage device; provided, that the books and records so maintained are convertible into clearly legible written form within a reasonable period of time. The books of the Partnership shall be maintained, for financial reporting purposes, on an accrual basis in accordance with U.S. GAAP. 8.2 Fiscal Year. The fiscal year of the Partnership shall be a fiscal year ending December 31. 8.3 Reports. (a) As soon as practicable, but in no event later than 120 days after the close of each fiscal year of the Partnership, the General Partner shall cause to be mailed or furnished to each Record Holder of a Unit as of a date selected by the General Partner in its discretion, an annual report containing financial statements of the Partnership for such fiscal year of the Partnership, presented in accordance with U.S. GAAP, including a balance sheet and statements of operations, Partnership equity and cash flows, such statements to be audited by a firm of independent public accountants selected by the General Partner. (b) As soon as practicable, but in no event later than 90 days after the close of each Quarter except the last Quarter of each fiscal year, the General Partner shall cause to be mailed or furnished to each Record Holder of a Unit, as of a date selected by the General Partner in its discretion, a report containing unaudited financial statements of the Partnership and such other information as may be required by applicable law, regulation or rule of any National Securities Exchange on which the Units are listed for trading, or as the General Partner determines to be necessary or appropriate. ARTICLE IX Tax Matters 9.1 Tax Returns and Information. The Partnership shall timely file all returns of the Partnership that are required for federal, state and local income tax purposes on the basis of the accrual method and a taxable year ending on C:\My Documents\Mlpagt.wpd EXECUTION COPY 40

December 31. The tax information reasonably required by Record Holders for federal and state income tax reporting purposes with respect to a taxable year shall be furnished to them within 90 days of the close of the calendar year in which the Partnership's taxable year ends. The classification, realization and recognition of income, gain, losses and deductions and other items shall be on the accrual method of accounting for federal income tax purposes. 9.2 Tax Elections. (a) The Partnership shall make the election under Section 754 of the Code in accordance with applicable regulations thereunder, subject to the reservation of the right to seek to revoke any such election upon the General Partner's determination that such revocation is in the best interests of the Limited Partners. Notwithstanding any other provision herein contained, for the purposes of computing the adjustments under Section 743(b) of the Code, the General Partner shall be authorized (but not required) to adopt a convention whereby the price paid by a transferee of a Limited Partner Interest that is traded on any National Securities Exchange will be deemed to be the lowest quoted closing price of such Limited Partner Interests on any National Securities Exchange on which such Limited Partner Interests are traded during the calendar month in which such transfer is deemed to occur pursuant to Section 6.2(g) without regard to the actual price paid by such transferee. (b) The Partnership shall elect to deduct expenses incurred in organizing the Partnership ratably over a sixty-month period as provided in Section 709 of the Code. (c) Except as otherwise provided herein, the General Partner shall determine whether the Partnership should make any other elections permitted by the Code. 9.3 Tax Controversies. Subject to the provisions hereof, the General Partner is designated as the Tax Matters Partner (as defined in the Code) and is authorized and required to represent the Partnership (at the Partnership's expense) in connection with all examinations of the Partnership's affairs by tax authorities, including resulting administrative and judicial proceedings, and to expend Partnership funds for professional services and costs associated therewith. Each Partner agrees to cooperate with the General Partner and to do or refrain from doing any or all things reasonably required by the General Partner to conduct such proceedings. 9.4 Withholding. Notwithstanding any other provision of this Agreement, the General Partner is authorized to take any action that it determines in its discretion to be necessary or appropriate to cause the Partnership and the Operating Partnership to comply with any withholding requirements established under the Code or any other federal, state or local law including, without limitation, pursuant to Sections 1441, 1442, 1445 and 1446 of the Code. To the extent that the Partnership is required or elects to withhold and pay over to any taxing authority any amount resulting from the allocation or distribution of income to any Partner or Assignee (including, without limitation, by reason of Section 1446 of the Code), the amount withheld may at the discretion of the General Partner be treated by the Partnership as a distribution of cash pursuant to Section 6.3 in the amount of such withholding from such Partner. ARTICLE X Admission of Partners 10.1 Admission of Initial Limited Partners. Upon the issuance by the Partnership of Common Units and Subordinated Units to EPC Partners II, as described in Section 5.2, EPC Partners II was admitted to the Partnership as a Limited Partner in respect of the Units issued to it. Upon the issuance by the Partnership of Common Units to the Underwriters as described in Section 5.3 in connection with the Initial Offering and the execution by each Underwriter of a Transfer Application, the General Partner admitted the Underwriters to the Partnership as Initial Limited Partners in respect of the Common Units purchased by them. Upon the issuance by the Partnership of Class A Special Units C:\My Documents\Mlpagt.wpd EXECUTION COPY 41

to Tejas as described in Section 5.3, the General Partner shall admit Tejas to the Partnership as an Initial Limited Partner in respect of the Class A Special Units issued to Tejas. 10.2 Admission of Substituted Limited Partner. By transfer of a Limited Partner Interest in accordance with Article IV, the transferor shall be deemed to have given the transferee the right to seek admission as a Substituted Limited Partner subject to the conditions of, and in the manner permitted under, this Agreement. A transferor of a Certificate representing a Limited Partner Interest shall, however, only have the authority to convey to a purchaser or other transferee who does not execute and deliver a Transfer Application (a) the right to negotiate such Certificate to a purchaser or other transferee and (b) the right to transfer the right to request admission as a Substituted Limited Partner to such purchaser or other transferee in respect of the transferred Limited Partner Interests. Each transferee of a Limited Partner Interest (including any nominee holder or an agent acquiring such Limited Partner Interest for the account of another Person) who executes and delivers a Transfer Application shall, by virtue of such execution and delivery, be an Assignee and be deemed to have applied to become a Substituted Limited Partner with respect to the Limited Partner Interests so transferred to such Person. Such Assignee shall become a Substituted Limited Partner (x) at such time as the General Partner consents thereto, which consent may be given or withheld in the General Partner's discretion, and (y) when any such admission is shown on the books and records of the Partnership. If such consent is withheld, such transferee shall be an Assignee. An Assignee shall have an interest in the Partnership equivalent to that of a Limited Partner with respect to allocations and distributions, including liquidating distributions, of the Partnership. With respect to voting rights attributable to Limited Partner Interests that are held by Assignees, the General Partner shall be deemed to be the Limited Partner with respect thereto and shall, in exercising the voting rights in respect of such Limited Partner Interests on any matter, vote such Limited Partner Interests at the written direction of the Assignee who is the Record Holder of such Limited Partner Interests. If no such written direction is received, such Limited Partner Interests will not be voted. An Assignee shall have no other rights of a Limited Partner. 10.3 Admission of Successor General Partner. A successor General Partner approved pursuant to Section 11.1 or 11.2 or the transferee of or successor to all of the General Partner's Partnership Interest as general partner in the Partnership pursuant to Section 4.6 who is proposed to be admitted as a successor General Partner shall be admitted to the Partnership as the General Partner, effective immediately prior to the withdrawal or removal of the predecessor or transferring General Partner pursuant to Section 11.1 or 11.2 or the transfer of the General Partner's Partnership Interest as a general partner in the Partnership pursuant to Section 4.6; provided, however, that no such successor shall be admitted to the Partnership until compliance with the terms of Section 4.6 has occurred and such successor has executed and delivered such other documents or instruments as may be required to effect such admission. Any such successor shall, subject to the terms hereof, carry on the business of the members of the Partnership Group without dissolution. 10.4 Admission of Additional Limited Partners. (a) A Person (other than the General Partner, an Initial Limited Partner or a Substituted Limited Partner) who makes a Capital Contribution to the Partnership in accordance with this Agreement shall be admitted to the Partnership as an Additional Limited Partner only upon furnishing to the General Partner (i) evidence of acceptance in form satisfactory to the General Partner of all of the terms and conditions of this Agreement, including the power of attorney granted in Section 2.6, and (ii) such other documents or instruments as may be required in the discretion of the General Partner to effect such Person's admission as an Additional Limited Partner. (b) Notwithstanding anything to the contrary in this Section 10.4, no Person shall be admitted as an Additional Limited Partner without the consent of the General Partner, which consent may be given or withheld in the General Partner's sole discretion. The admission of any Person as an Additional Limited Partner shall become effective on the date upon which the name of such Person is recorded as such in the books and records of the Partnership, following the consent of the General Partner to such admission. C:\My Documents\Mlpagt.wpd EXECUTION COPY 42

10.5 Amendment of Agreement and Certificate of Limited Partnership. To effect the admission to the Partnership of any Partner, the General Partner shall take all steps necessary and appropriate under the Delaware Act to amend the records of the Partnership to reflect such admission and, if necessary, to prepare as soon as practicable an amendment to this Agreement and, if required by law, the General Partner shall prepare and file an amendment to the Certificate of Limited Partnership, and the General Partner may for this purpose, among others, exercise the power of attorney granted pursuant to Section 2.6. ARTICLE XI Withdrawal or Removal of Partners 11.1 Withdrawal of the General Partner. (a) The General Partner shall be deemed to have withdrawn from the Partnership upon the occurrence of any one of the following events (each such event herein referred to as an ''Event of Withdrawal''): (i) the General Partner voluntarily withdraws from the Partnership by giving written notice to the other Partners (and it shall be deemed that the General Partner has withdrawn pursuant to this Section 11.1(a)(i) if the General Partner voluntarily withdraws as general partner of the Operating Partnership); (ii) the General Partner transfers all of its rights as General Partner pursuant to Section 4.6; (iii) the General Partner is removed pursuant to Section 11.2; (iv) the General Partner (A) makes a general assignment for the benefit of creditors; (B) files a voluntary bankruptcy petition for relief under Chapter 7 of the United States Bankruptcy Code; (C) files a petition or answer seeking for itself a liquidation, dissolution or similar relief (but not a reorganization) under any law; (D) files an answer or other pleading admitting or failing to contest the material allegations of a petition filed against the General Partner in a proceeding of the type described in clauses (A)-(C) of this Section 11.1(a)(iv); or (E) seeks, consents to or acquiesces in the appointment of a trustee (but not a debtor-in-possession), receiver or liquidator of the General Partner or of all or any substantial part of its properties; (v) a final and non-appealable order of relief under Chapter 7 of the United States Bankruptcy Code is entered by a court with appropriate jurisdiction pursuant to a voluntary or involuntary petition by or against the General Partner; or (vi) (A) in the event the General Partner is a corporation, a certificate of dissolution or its equivalent is filed for the General Partner, or 90 days expire after the date of notice to the General Partner of revocation of its charter without a reinstatement of its charter, under the laws of its state of incorporation; (B) in the event the General Partner is a partnership or a limited liability company, the dissolution and commencement of winding up of the General Partner; (C) in the event the General Partner is acting in such capacity by virtue of being a trustee of a trust, the termination of the trust; (D) in the event the General Partner is a natural person, his death or adjudication of incompetency; and (E) otherwise in the event of the termination of the General Partner. If an Event of Withdrawal specified in Section 11.1(a)(iv), (v) or (vi)(A), (B), (C) or (E) occurs, the withdrawing General Partner shall give notice to the Limited Partners within 30 days after such occurrence. The Partners hereby agree that only the Events of Withdrawal described in this Section 11.1 shall result in the withdrawal of the General Partner from the Partnership. C:\My Documents\Mlpagt.wpd EXECUTION COPY 43

(b) Withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall not constitute a breach of this Agreement under the following circumstances: (i) at any time during the period beginning on the Closing Date and ending at 12:00 midnight, Eastern Standard Time, on December 31, 2008, the General Partner voluntarily withdraws by giving at least 90 days' advance notice of its intention to withdraw to the Limited Partners; provided that prior to the effective date of such withdrawal, the withdrawal is approved by Unitholders holding at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) and the General Partner delivers to the Partnership an Opinion of Counsel (''Withdrawal Opinion of Counsel'') that such withdrawal (following the selection of the successor General Partner) would not result in the loss of the limited liability of any Limited Partner or of a member of the Operating Partnership or cause the Partnership or the Operating Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not previously treated as such); (ii) at any time after 12:00 midnight, Eastern Standard Time, on December 31, 2008, the General Partner voluntarily withdraws by giving at least 90 days' advance notice to the Unitholders, such withdrawal to take effect on the date specified in such notice; (iii) at any time that the General Partner ceases to be the General Partner pursuant to Section 11.1(a)(ii) or is removed pursuant to Section 11.2; or (iv) notwithstanding clause (i) of this sentence, at any time that the General Partner voluntarily withdraws by giving at least 90 days' advance notice of its intention to withdraw to the Limited Partners, such withdrawal to take effect on the date specified in the notice, if at the time such notice is given one Person and its Affiliates (other than the General Partner and its Affiliates) own beneficially or of record or control at least 50% of the Outstanding Units. The withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall also constitute the withdrawal of the General Partner as general partner or managing member, as the case may be, of the other Group Members. If the General Partner gives a notice of withdrawal pursuant to Section 11.1(a)(i), the holders of a Unit Majority, may, prior to the effective date of such withdrawal, elect a successor General Partner. The Person so elected as successor General Partner shall automatically become the successor general partner or managing member, as the case may be, of the other Group Members of which the General Partner is a general partner or managing member. If, prior to the effective date of the General Partner's withdrawal, a successor is not selected by the Unitholders as provided herein or the Partnership does not receive a Withdrawal Opinion of Counsel, the Partnership shall be dissolved in accordance with Section 12.1. Any successor General Partner elected in accordance with the terms of this Section 11.1 shall be subject to the provisions of Section 10.3. 11.2 Removal of the General Partner. The General Partner may be removed if such removal is approved by Unitholders holding at least 662/3% of the Outstanding Units (including Units held by the General Partner and its Affiliates but excluding Class A Special Units). Any such action by such holders for removal of the General Partner must also provide for the election of a successor General Partner by the Unitholders holding a Unit Majority. Such removal shall be effective immediately following the admission of a successor General Partner pursuant to Section 10.3. The removal of the General Partner shall also automatically constitute the removal of the General Partner as general partner or managing member, as the case may be, of the other Group Members of which the General Partner is a general partner or managing member. If a Person is elected as a successor General Partner in accordance with the terms of this Section 11.2, such Person shall, upon admission pursuant to Section 10.3, automatically become a successor general partner or managing member, as the case may be, of the other Group Members of which the General Partner is a general partner or managing member. The right of the holders of Outstanding Units to remove the General Partner shall not exist or be exercised unless the Partnership has received an opinion opining as to the matters covered by a Withdrawal Opinion of Counsel. Any successor General Partner elected in accordance with the terms of this Section 11.2 shall be subject to the provisions of Section 10.3. 11.3 Interest of Departing Partner and Successor General Partner. (a) In the event of (i) withdrawal of the General Partner under circumstances where such withdrawal does not violate this Agreement or (ii) removal of the General Partner by the holders of Outstanding Units under circumstances where Cause does not exist, if a successor General Partner is elected in accordance with the terms of Section 11.1 or 11.2, the Departing Partner shall have the option exercisable prior to the effective date of the departure of such Departing Partner to require its successor to purchase its Partnership Interest as a general partner in the Partnership and C:\My Documents\Mlpagt.wpd EXECUTION COPY 44

its partnership or member interest as the general partner or managing member in the other Group Members (collectively, the ''Combined Interest'') in exchange for an amount in cash equal to the fair market value of such Combined Interest, such amount to be determined and payable as of the effective date of its departure or, if there is not agreement as to the fair market value of such Combined Interest, within ten (10) days after such agreement is reached. If the General Partner is removed by the Unitholders under circumstances where Cause exists or if the General Partner withdraws under circumstances where such withdrawal violates this Agreement or the Operating Partnership Agreement, and if a successor General Partner is elected in accordance with the terms of Section 11.1 or 11.2, such successor shall have the option, exercisable prior to the effective date of the departure of such Departing Partner, to purchase the Combined Interest for such fair market value of such Combined Interest. In either event, the Departing Partner shall be entitled to receive all reimbursements due such Departing Partner pursuant to Section 7.4, including any employee-related liabilities (including severance liabilities), incurred in connection with the termination of any employees employed by the General Partner for the benefit of the Partnership or the other Group Members. (b) For purposes of this Section 11.3(a), the fair market value of the Combined Interest shall be determined by agreement between the Departing Partner and its successor or, failing agreement within 30 days after the effective date of such Departing Partner's departure, by an independent investment banking firm or other independent expert selected by the Departing Partner and its successor, which, in turn, may rely on other experts, and the determination of which shall be conclusive as to such matter. If such parties cannot agree upon one independent investment banking firm or other independent expert within 45 days after the effective date of such departure, then the Departing Partner shall designate an independent investment banking firm or other independent expert, the Departing Partner's successor shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert, which third independent investment banking firm or other independent expert shall determine the fair market value of the Combined Interest. In making its determination, such third independent investment banking firm or other independent expert may consider the then current trading price of Units on any National Securities Exchange on which Units are then listed, the value of the Partnership's assets, the rights and obligations of the Departing Partner and other factors it may deem relevant. (c) If the Combined Interest is not purchased in the manner set forth in Section 11.3(a), the Departing Partner (or its transferee) shall become a Limited Partner and its Combined Interest shall be converted into Common Units pursuant to a valuation made by an investment banking firm or other independent expert selected pursuant to Section 11.3(a), without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). Any successor General Partner shall indemnify the Departing Partner (or its transferee) as to all debts and liabilities of the Partnership arising on or after the date on which the Departing Partner (or its transferee) becomes a Limited Partner. For purposes of this Agreement, conversion of the Combined Interest to Common Units will be characterized as if the General Partner (or its transferee) contributed its Combined Interest to the Partnership in exchange for the newly issued Common Units. (d) If a successor General Partner is elected in accordance with the terms of Section 11.1 or 11.2 and the option described in Section 11.3(a) is not exercised by the party entitled to do so, the successor General Partner shall, at the effective date of its admission to the Partnership, contribute to the Partnership cash in the amount equal to 1/99th of the Net Agreed Value of the Partnership's assets on such date. In such event, such successor General Partner shall, subject to the following sentence, be entitled to 1% of all Partnership allocations and distributions. The successor General Partner shall cause this Agreement to be amended to reflect that, from and after the date of such successor General Partner's admission, the successor General Partner's interest in all Partnership distributions and allocations shall be 1%. 11.4 Termination of Subordination Period, Conversion of Subordinated Units and Extinguishment of Cumulative Common Unit Arrearages. Notwithstanding any provision of this Agreement, if the General Partner is removed as general partner of the Partnership under circumstances where Cause does not exist and Units held by the General Partner and its Affiliates are not voted in favor of such removal, (i) the Subordination Period will end and all Outstanding Subordinated Units will immediately and automatically convert into Common Units on a one-for-one basis and (ii) all Cumulative Common Unit Arrearages on the Common Units will be extinguished. C:\My Documents\Mlpagt.wpd EXECUTION COPY 45

11.5 Withdrawal of Limited Partners . No Limited Partner shall have any right to withdraw from the Partnership; provided, however, that when a transferee of a Limited Partner's Limited Partner Interest becomes a Record Holder of the Limited Partner Interest so transferred, such transferring Limited Partner shall cease to be a Limited Partner with respect to the Limited Partner Interest so transferred. ARTICLE XII Dissolution and Liquidation 12.1 Dissolution. The Partnership shall not be dissolved by the admission of Substituted Limited Partners or Additional Limited Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. Upon the removal or withdrawal of the General Partner, if a successor General Partner is elected pursuant to Section 11.1 or 11.2, the Partnership shall not be dissolved and such successor General Partner shall continue the business of the Partnership. The Partnership shall dissolve, and (subject to Section 12.2) its affairs shall be wound up, upon: (a) the expiration of its term as provided in Section 2.7; (b) an Event of Withdrawal of the General Partner as provided in Section 11.1(a) (other than Section 11.1(a)(ii)), unless a successor is elected and an Opinion of Counsel is received as provided in Section 11.1(b) or 11.2 and such successor is admitted to the Partnership pursuant to Section 10.3; (c) an election to dissolve the Partnership by the General Partner that is approved by the holders of a Unit Majority; (d) the entry of a decree of judicial dissolution of the Partnership pursuant to the provisions of the Delaware Act; or (e) the sale of all or substantially all of the assets and properties of the Partnership Group. 12.2 Continuation of the Business of the Partnership After Dissolution. Upon (a) dissolution of the Partnership following an Event of Withdrawal caused by the withdrawal or removal of the General Partner as provided in Section 11.1(a)(i) or (iii) and the failure of the Partners to select a successor to such Departing Partner pursuant to Section 11.1 or 11.2, then within 90 days thereafter, or (b) dissolution of the Partnership upon an event constituting an Event of Withdrawal as defined in Section 11.1(a)(iv), (v) or (vi), then, to the maximum extent permitted by law, within 180 days thereafter, the holders of a Unit Majority may elect to reconstitute the Partnership and continue its business on the same terms and conditions set forth in this Agreement by forming a new limited partnership on terms identical to those set forth in this Agreement and having as the successor general partner a Person approved by the holders of a Unit Majority. Unless such an election is made within the applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then: (i) the reconstituted Partnership shall continue until the end of the term set forth in Section 2.7 unless earlier dissolved in accordance with this Article XII; (ii) if the successor General Partner is not the former General Partner, then the interest of the former General Partner shall be treated in the manner provided in Section 11.3; and (iii) all necessary steps shall be taken to cancel this Agreement and the Certificate of Limited Partnership and to enter into and, as necessary, to file a new partnership agreement and certificate of limited partnership, and the successor general partner may for this purpose exercise the powers of attorney granted the General Partner pursuant C:\My Documents\Mlpagt.wpd EXECUTION COPY 46

to Section 2.6; provided, that the right of the holders of a Unit Majority to approve a successor General Partner and to reconstitute and to continue the business of the Partnership shall not exist and may not be exercised unless the Partnership has received an Opinion of Counsel that (x) the exercise of the right would not result in the loss of limited liability of any Limited Partner and (y) neither the Partnership, the reconstituted limited partnership nor the Operating Partnership would be treated as an association taxable as a corporation or otherwise be taxable as an entity for federal income tax purposes upon the exercise of such right to continue. 12.3 Liquidator. Upon dissolution of the Partnership, unless the Partnership is continued under an election to reconstitute and continue the Partnership pursuant to Section 12.2, the General Partner shall select one or more Persons to act as Liquidator. The Liquidator (if other than the General Partner) shall be entitled to receive such compensation for its services as may be approved by holders of at least a majority of the Outstanding Common Units and Subordinated Units voting as a single class. The Liquidator (if other than the General Partner) shall agree not to resign at any time without 15 days' prior notice and may be removed at any time, with or without cause, by notice of removal approved by holders of at least a majority of the Outstanding Common Units and Subordinated Units voting as a single class. Upon dissolution, removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of at least a majority of the Outstanding Common Units and Subordinated Units voting as a single class. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to refer also to any such successor or substitute Liquidator approved in the manner herein provided. Except as expressly provided in this Article XII, the Liquidator approved in the manner provided herein shall have and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the General Partner under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth in Section 7.3(b)) to the extent necessary or desirable in the good faith judgment of the Liquidator to carry out the duties and functions of the Liquidator hereunder for and during such period of time as shall be reasonably required in the good faith judgment of the Liquidator to complete the winding up and liquidation of the Partnership as provided for herein. 12.4 Liquidation. The Liquidator shall proceed to dispose of the assets of the Partnership, discharge its liabilities, and otherwise wind up its affairs in such manner and over such period as the Liquidator determines to be in the best interest of the Partners, subject to Section 17-804 of the Delaware Act and the following: (a) Disposition of Assets. The assets may be disposed of by public or private sale or by distribution in kind to one or more Partners on such terms as the Liquidator and such Partner or Partners may agree. If any property is distributed in kind, the Partner receiving the property shall be deemed for purposes of Section 12.4(c) to have received cash equal to its fair market value; and contemporaneously therewith, appropriate cash distributions must be made to the other Partners. The Liquidator may, in its absolute discretion, defer liquidation or distribution of the Partnership's assets for a reasonable time if it determines that an immediate sale or distribution of all or some of the Partnership's assets would be impractical or would cause undue loss to the Partners. The Liquidator may, in its absolute discretion, distribute the Partnership's assets, in whole or in part, in kind if it determines that a sale would be impractical or would cause undue loss to the Partners. (b) Discharge of Liabilities. Liabilities of the Partnership include amounts owed to Partners otherwise than in respect of their distribution rights under Article VI. With respect to any liability that is contingent, conditional or unmatured or is otherwise not yet due and payable, the Liquidator shall either settle such claim for such amount as it thinks appropriate or establish a reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be distributed as additional liquidation proceeds. (c) Liquidation Distributions. All property and all cash in excess of that required to discharge liabilities as provided in Section 12.4(b) shall be distributed to the Partners in accordance with, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (other than those made by reason of distributions pursuant to this Section 12.4(c)) for the taxable year C:\My Documents\Mlpagt.wpd EXECUTION COPY 47

of the Partnership during which the liquidation of the Partnership occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable year (or, if later, within 90 days after said date of such occurrence). 12.5 Cancellation of Certificate of Limited Partnership. Upon the completion of the distribution of Partnership cash and property as provided in Section 12.4 in connection with the liquidation of the Partnership, the Partnership shall be terminated and the Certificate of Limited Partnership and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken. 12.6 Return of Contributions. The General Partner shall not be personally liable for, and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate, the return of the Capital Contributions of the Limited Partners or Unitholders, or any portion thereof, it being expressly understood that any such return shall be made solely from Partnership assets. 12.7 Waiver of Partition. To the maximum extent permitted by law, each Partner hereby waives any right to partition of the Partnership property. 12.8 Capital Account Restoration. No Partner shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Partnership. ARTICLE XIII Amendment of Partnership Agreement; Meetings; Record Date 13.1 Amendment to be Adopted Solely by the General Partner. Each Partner agrees that the General Partner, without the approval of any Partner or Assignee, may amend any provision of this Agreement and execute, swear to, acknowledge, deliver, file and record whatever documents may be required in connection therewith, to reflect: (a) a change in the name of the Partnership, the location of the principal place of business of the Partnership, the registered agent of the Partnership or the registered office of the Partnership; (b) admission, substitution, withdrawal or removal of Partners in accordance with this Agreement; (c) a change that, in the sole discretion of the General Partner, is necessary or advisable to qualify or continue the qualification of the Partnership as a limited partnership or a partnership in which the Limited Partners have limited liability under the laws of any state or to ensure that no Group Member will be treated as an association taxable as a corporation or otherwise taxed as an entity for federal income tax purposes; (d) a change that, in the discretion of the General Partner, (i) does not adversely affect the Limited Partners in any material respect, (ii) is necessary or advisable to (A) satisfy any requirements, conditions or guidelines contained in any opinion, directive, order, ruling or regulation of any federal or state agency or judicial authority or contained in any federal or state statute (including the Delaware Act) or (B) facilitate the trading of the Limited Partner Interests (including the division of any class or classes of Outstanding Limited Partner Interests into different classes to facilitate uniformity of tax consequences within such classes of Limited Partner Interests) or comply with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Limited Partner Interests are or will be listed for trading, compliance with any of which the General Partner determines in its discretion to be in the best interests of the Partnership and the Limited Partners, (iii) is necessary or advisable in connection with action taken by the General Partner pursuant to Section 5.10 or (iv) is required to C:\My Documents\Mlpagt.wpd EXECUTION COPY 48

effect the intent expressed in the Registration Statement or the intent of the provisions of this Agreement or is otherwise contemplated by this Agreement; (e) a change in the fiscal year or taxable year of the Partnership and any changes that, in the discretion of the General Partner, are necessary or advisable as a result of a change in the fiscal year or taxable year of the Partnership including, if the General Partner shall so determine, a change in the definition of ''Quarter'' and the dates on which distributions are to be made by the Partnership; (f) an amendment that is necessary, in the Opinion of Counsel, to prevent the Partnership, or the General Partner or its directors, officers, trustees or agents from in any manner being subjected to the provisions of the Investment Company Act of 1940, as amended, the Investment Advisers Act of 1940, as amended, or ''plan asset'' regulations adopted under the Employee Retirement Income Security Act of 1974, as amended, regardless of whether such are substantially similar to plan asset regulations currently applied or proposed by the United States Department of Labor; (g) subject to the terms of Section 5.7, an amendment that, in the discretion of the General Partner, is necessary or advisable in connection with the authorization of issuance of any class or series of Partnership Securities pursuant to Section 5.6; (h) any amendment expressly permitted in this Agreement to be made by the General Partner acting alone; (i) an amendment effected, necessitated or contemplated by a Merger Agreement approved in accordance with Section 14.3; (j) an amendment that, in the discretion of the General Partner, is necessary or advisable to reflect, account for and deal with appropriately the formation by the Partnership of, or investment by the Partnership in, any corporation, partnership, joint venture, limited liability company or other entity other than the Operating Partnership, in connection with the conduct by the Partnership of activities permitted by the terms of Section 2.4; (k) a merger or conveyance pursuant to Section 14.3(d); or (l) any other amendments substantially similar to the foregoing. 13.2 Amendment Procedures. Except as provided in Sections 13.1 and 13.3, all amendments to this Agreement shall be made in accordance with the following requirements. Amendments to this Agreement may be proposed only by or with the consent of the General Partner which consent may be given or withheld in its sole discretion. A proposed amendment shall be effective upon its approval by the holders of a Unit Majority, unless a greater or different percentage is required under this Agreement or by Delaware law. A proposed amendment that adversely alters the powers, obligations or special rights of the Class A Special Units set forth herein shall be effective upon its approval by the holders of a majority of the Class A Special Units. Each proposed amendment that requires the approval of the holders of a specified percentage of Outstanding Units shall be set forth in a writing that contains the text of the proposed amendment. If such an amendment is proposed, the General Partner shall seek the written approval of the requisite percentage of Outstanding Units or call a meeting of the Unitholders to consider and vote on such proposed amendment. The General Partner shall notify all Record Holders upon final adoption of any such proposed amendments. 13.3 Amendment Requirements.

Outstanding Units whose aggregate Outstanding Units constitute not less than the voting requirement sought to be reduced. (b) Notwithstanding the provisions of Sections 13.1 and 13.2, no amendment to this Agreement may (i) enlarge the obligations of any Limited Partner without its consent, unless such shall have occurred as a result of an amendment approved pursuant to Section 13.3(c), (ii) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable to, the General Partner or any of its Affiliates without its consent, which consent may be given or withheld in its sole discretion, (iii) change Section 12.1(a) or 12.1(c), or (iv) change the term of the Partnership or, except as set forth in Section 12.1(c), give any Person the right to dissolve the Partnership.

(d) Notwithstanding any other provision of this Agreement, except for amendments pursuant to Section 13.1 and except as otherwise provided by Section 14.3(b), no amendments shall become effective without the approval of the holders of at least 90% of the Outstanding Common Units and Subordinated Units voting as a single class unless the Partnership obtains an Opinion of Counsel to the effect that such amendment will not affect the limited liability of any Limited Partner under applicable law. (e) Except as provided in Section 13.1, this Section 13.3 shall only be amended with the approval of the holders of at least 90% of the Outstanding Common Units and Subordinated Units voting as a single class. 13.4 Special Meetings. All acts of Limited Partners to be taken pursuant to this Agreement shall be taken in the manner provided in this Article XIII. Special meetings of the Limited Partners may be called by the General Partner or by Limited Partners owning 20% or more of the Outstanding Limited Partner Interests of the class or classes for which a meeting is proposed. Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and indicating the general or specific purposes for which the special meeting is to be called. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the meeting to the Limited Partners either directly or indirectly through the Transfer Agent. A meeting shall be held at a time and place determined by the General Partner on a date not less than 10 days nor more than 60 days after the mailing of notice of the meeting. Limited Partners shall not vote on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners' limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business. 13.5 Notice of a Meeting. Notice of a meeting called pursuant to Section 13.4 shall be given to the Record Holders of the class or classes of Limited Partner Interests for which a meeting is proposed in writing by mail or other means of written communication in accordance with Section 16.1. The notice shall be deemed to have been given at the time when deposited in the mail or sent by other means of written communication. 13.6 Record Date. For purposes of determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 13.11 the General Partner may set a Record Date, which shall not be less than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Limited Partner Interests are listed for trading, in which case the rule, regulation, guideline or requirement of such C:\My Documents\Mlpagt.wpd EXECUTION COPY 50

exchange shall govern) or (b) in the event that approvals are sought without a meeting, the date by which Limited Partners are requested in writing by the General Partner to give such approvals. 13.7 Adjournment. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be fixed, if the time and place thereof are announced at the meeting at which the adjournment is taken, unless such adjournment shall be for more than 45 days. At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days or if a new Record Date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in accordance with this Article XIII. 13.8 Waiver of Notice. Approval of Meeting; Approval of Minutes. The transactions of any meeting of Limited Partners, however called and noticed, and whenever held, shall be as valid as if it had occurred at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy, and if, either before or after the meeting, Limited Partners representing such quorum who were present in person or by proxy and entitled to vote, sign a written waiver of notice or an approval of the holding of the meeting or an approval of the minutes thereof. All waivers and approvals shall be filed with the Partnership records or made a part of the minutes of the meeting. Attendance of a Limited Partner at a meeting shall constitute a waiver of notice of the meeting, except when the Limited Partner does not approve, at the beginning of the meeting, of the transaction of any business because the meeting is not lawfully called or convened; and except that attendance at a meeting is not a waiver of any right to disapprove the consideration of matters required to be included in the notice of the meeting, but not so included, if the disapproval is expressly made at the meeting. 13.9 Quorum. The holders of a majority of the Outstanding Limited Partner Interests of the class or classes for which a meeting has been called (including Limited Partner Interests deemed owned by the General Partner) represented in person or by proxy shall constitute a quorum at a meeting of Limited Partners of such class or classes unless any such action by the Limited Partners requires approval by holders of a greater percentage of such Limited Partner Interests, in which case the quorum shall be such greater percentage. At any meeting of the Limited Partners duly called and held in accordance with this Agreement at which a quorum is present, the act of Limited Partners holding Outstanding Limited Partner Interests that in the aggregate represent a majority of the Outstanding Limited Partner Interests entitled to vote and be present in person or by proxy at such meeting shall be deemed to constitute the act of all Limited Partners, unless a greater or different percentage is required with respect to such action under the provisions of this Agreement, in which case the act of the Limited Partners holding Outstanding Limited Partner Interests that in the aggregate represent at least such greater or different percentage shall be required. The Limited Partners present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough Limited Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by the required percentage of Outstanding Limited Partner Interests specified in this Agreement (including Limited Partner Interests deemed owned by the General Partner). In the absence of a quorum any meeting of Limited Partners may be adjourned from time to time by the affirmative vote of holders of at least a majority of the Outstanding Limited Partner Interests entitled to vote at such meeting (including Limited Partner Interests deemed owned by the General Partner) represented either in person or by proxy, but no other business may be transacted, except as provided in Section 13.7. 13.10 Conduct of a Meeting. The General Partner shall have full power and authority concerning the manner of conducting any meeting of the Limited Partners or solicitation of approvals in writing, including the determination of Persons entitled to vote, the existence of a quorum, the satisfaction of the requirements of Section 13.4, the conduct of voting, the validity and effect of any proxies and the determination of any controversies, votes or challenges arising in connection with or during the meeting or voting. The General Partner shall designate a Person to serve as chairman of any meeting and shall further designate a Person to take the minutes of any meeting. All minutes shall be kept with the records of the Partnership maintained by the General Partner. The General Partner may make such other regulations consistent with applicable law and this Agreement as it may deem advisable concerning the conduct of any meeting of the Limited Partners or solicitation of approvals in writing, including regulations in regard to the appointment of C:\My Documents\Mlpagt.wpd EXECUTION COPY 51

proxies, the appointment and duties of inspectors of votes and approvals, the submission and examination of proxies and other evidence of the right to vote, and the revocation of approvals in writing. 13.11 Action Without a Meeting. If authorized by the General Partner, any action that may be taken at a meeting of the Limited Partners may be taken without a meeting if an approval in writing setting forth the action so taken is signed by Limited Partners owning not less than the minimum percentage of the Outstanding Limited Partner Interests (including Limited Partner Interests deemed owned by the General Partner) that would be necessary to authorize or take such action at a meeting at which all the Limited Partners were present and voted (unless such provision conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Limited Partner Interests are listed for trading, in which case the rule, regulation, guideline or requirement of such exchange shall govern). Prompt notice of the taking of action without a meeting shall be given to the Limited Partners who have not approved in writing. The General Partner may specify that any written ballot submitted to Limited Partners for the purpose of taking any action without a meeting shall be returned to the Partnership within the time period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Limited Partner Interests held by the Limited Partners the Partnership shall be deemed to have failed to receive a ballot for the Limited Partner Interests that were not voted. If approval of the taking of any action by the Limited Partners is solicited by any Person other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until (a) they are deposited with the Partnership in care of the General Partner, (b) approvals sufficient to take the action proposed are dated as of a date not more than 90 days prior to the date sufficient approvals are deposited with the Partnership and (c) an Opinion of Counsel is delivered to the General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular matter (i) will not cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners' limited liability, and (ii) is otherwise permissible under the state statutes then governing the rights, duties and liabilities of the Partnership and the Partners. 13.12 Voting and Other Rights. (a) Only those Record Holders of the Limited Partner Interests on the Record Date set pursuant to Section 13.6 (and also subject to the limitations contained in the definition of ''Outstanding'') shall be entitled to notice of, and to vote at, a meeting of Limited Partners or to act with respect to matters as to which the holders of the Outstanding Limited Partner Interests have the right to vote or to act. All references in this Agreement to votes of, or other acts that may be taken by, the Outstanding Limited Partner Interests shall be deemed to be references to the votes or acts of the Record Holders of such Outstanding Limited Partner Interests. (b) With respect to Limited Partner Interests that are held for a Person's account by another Person (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), in whose name such Limited Partner Interests are registered, such other Person shall, in exercising the voting rights in respect of such Limited Partner Interests on any matter, and unless the arrangement between such Persons provides otherwise, vote such Limited Partner Interests in favor of, and at the direction of, the Person who is the beneficial owner, and the Partnership shall be entitled to assume it is so acting without further inquiry. The provisions of this Section 13.12(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 4.3. ARTICLE XIV Merger 14.1 Authority. The Partnership may merge or consolidate with one or more corporations, limited liability companies, business trusts or associations, real estate investment trusts, common law trusts or unincorporated businesses, including a general partnership or limited partnership, formed under the laws of the State of Delaware or C:\My Documents\Mlpagt.wpd EXECUTION COPY 52

Gas Production being 350 billion cubic feet on a cumulative basis during calendar year 2001 as such period may be extended due to Force Majeure Events. C:\My Documents\Mlpagt.wpd EXECUTION COPY 73

ARTICLE2: ORGANIZATION 2.01 Formation. The Company was organized as a Delaware limited liability company by the filing of a Certificate of Formation (the "Delaware Certificate") on April 9, 1998 with the Secretary of State of Delaware pursuant to the Act. 2.02 Name. The name of the Company is "Enterprise Products GP, LLC" and all Company business must be conducted in that name or such other names that comply with Law as the Board of Directors may select. 2.03 Registered Office; Registered Agent; Principal Office in the United States; Other Offices. The registered office of the Company required by the Act to be maintained in the State of Delaware shall be the office of the initial registered agent named in the Delaware Certificate or such other office (which need not be a place of business of the Company) as the Board of Directors may designate in the manner provided by Law. The registered agent of the Company in the State of Delaware shall be the initial registered agent named in the Delaware Certificate or such other Person or Persons as the Board of Directors may designate in the manner provided by Law. The principal office of the Company in the United States shall be at such place as the Board of Directors may designate, which need not be in the State of Delaware, and the Company shall maintain records there or such other place as the Board of Directors shall designate and shall keep the street address of such principal office at the registered office of the Company in the State of Delaware. The Company may have such other offices as the Board of Directors may designate. 2.04 Purposes. The purposes of the Company are the transaction of any or all lawful business for which limited liability companies may be organized under the Act; provided, however, that for so long as it is the general partner of the MLP, (a) the Company's sole business will be to act as the general partner or managing member of the MLP, the OLP, and any other partnership or limited liability company of which the MLP or the OLP is, directly or indirectly, a partner or managing member and to undertake activities that are ancillary or related thereto (including being a limited partner in the partnership), and (b) The Company shall not engage in any business or activity or incur any debts or liabilities except in connection with or incidental to (i) its performance as general partner or managing member of one or more Group Members or as described in or contemplated by the Registration Statement or (ii) the acquiring, owning or disposing of debt or equity securities in any Group Member. 2.05 Term.

The Members intend that the Company not be a partnership (including a limited partnership) or joint venture, and that no Member be a partner or joint venturer of any other Member, for any purposes other than federal and state tax purposes, and this Agreement may not be construed to suggest otherwise. -2-

ARTICLE 3: MATTERS RELATING TO MEMBERS 3.01 Members. DDLLC and EPC II were previously admitted as Members of the Company, and Tejas Energy is hereby admitted as a Member of the Company effective as of the date first set forth above. 3.02 Creation of Additional Membership Interest. Additional Membership Interests may be created and issued to existing Members only with the unanimous approval of all Members. Additional Membership Interests may be created and issued to other Persons, and such other Persons may be admitted to the Company as Members, only with the unanimous consent of the existing Members, on such terms and conditions as the existing Members may unanimously determine at the time of admission. The terms of admission or issuance must specify the Sharing Ratios applicable thereto and may provide for the creation of different classes or groups of Members having different rights, powers, and duties. The Board of Directors may reflect the creation of any new class or group in an amendment to this Agreement indicating the different rights, powers, and duties, and such an amendment need be executed only by the Board of Directors. Any such admission is effective only after the new Member has executed and delivered to the Members an instrument containing the notice address of the new Member, the Assignee's ratification of this Agreement and agreement to be bound by it, and its confirmation that the representations and warranties in Section 10.01 are true and correct with respect to it. The provisions of this Section 3.02 shall not apply to Dispositions of Membership Interests or admissions of Assignees in connection therewith, such matters being governed by Section 9.01. 3.03 Access to Information. Each Member shall be entitled to receive any information that it may request concerning the Company; provided, however, that this Section 3.03 shall not obligate the Company, the Board of Directors or the Officers to create any information that does not already exist at the time of such request (other than to convert existing information from one medium to another, such as providing a printout of information that is stored in a computer database). Each Member shall also have the right, upon reasonable notice, and at all reasonable times during usual business hours to inspect the properties of the Company and to audit, examine and make copies of the books of account and other records of the Company. Such right may be exercised through any agent or employee of such Member designated in writing by it or by an independent public accountant, engineer, attorney or other consultant so designated. The Member making the request shall bear all costs and expenses incurred in any inspection, examination or audit made on such Member's behalf. 3.04 Liability to Third Parties. No Member shall be liable for the debts, obligations or liabilities of the Company. 3.05 Withdrawal. A Member does not have the right to Withdraw; provided, however, a Member shall have the power to Withdraw at any time in violation of this Agreement. If a Member exercises such power in violation of this Agreement, (a) such Withdrawing Member shall be liable to the Company and the other Members and their Affiliates for all monetary damages suffered by them as a result of such Withdrawal; (b) such other Members shall, in addition thereto, have the rights set forth in Article 11; and (c) such Withdrawing Member shall not have any rights -3-

under Section 18-604 of the Act. In no event shall the Company or any Member have the right, through specific performance or otherwise, to prevent a Member from Withdrawing in violation of this Agreement. ARTICLE 4: CAPITAL CONTRIBUTIONS; CAPITAL ACCOUNTS 4.01 Capital Contributions. In exchange for its Membership Interest in the Company, DDLLC has made certain Capital Contributions. EPC II and Tejas Energy are the assignees of their respective Membership Interests in the Company. 4.02 Loans. If the Company does not have sufficient cash to pay its obligations, any Member(s) that may agree to do so with the consent of the Board of Directors may advance all or part of the needed funds to or on behalf of the Company. An advance described in this Section 4.02 constitutes a loan from the Member to the Company, bears interest at a rate determined by the Board of Directors from the date of the advance until the date of payment, and is not a Capital Contribution. 4.03 Return of Contributions. Except as expressly provided herein, a Member is not entitled to the return of any part of its Capital Contributions or to be paid interest in respect of either its Capital Account or its Capital Contributions. An unrepaid Capital Contribution is not a liability of the Company or of any Member. A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any Member's Capital Contributions. 4.04 Capital Accounts. A Capital Account shall be established and maintained for each Member. Each Member's Capital Account shall be increased by (a) the amount of money contributed by that Member to the Company, (b) the fair market value of property contributed by that Member to the Company (net of liabilities secured by such contributed property that the Company is considered to assume or take subject to under Section 752 of the Code), and (c) allocations to that Member of Company income and gain (or items thereof), including income and gain exempt from tax and income and gain described in Treasury Regulation Section 1.704-1(b)(2)(iv)(g), but excluding income and gain described in Treasury Regulation Section 1.704-1(b)(4)(i), and shall be decreased by (d) the amount of money distributed to that Member by the Company, (e) the fair market value of property distributed to that Member by the Company (net of liabilities secured by such distributed property that such Member is considered to assume or take subject to under Section 752 of the Code), (f) allocations to that Member of expenditures of the Company described (or treated as described) in Section 705(a)(2)(B) of the Code, and (g) allocations of Company loss and deduction (or items thereof), including loss and deduction described in Treasury Regulation Section 1.704-1(b)(2)(iv)(g), but excluding items described in (f) above and loss or deduction described in Treasury Regulation Sections 1.704-1(b)(4)(i) or 1.704-1(b)(4)(iii). The Members' Capital Accounts shall also be maintained and adjusted as permitted by the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv)(f) and as required by the other provisions of Treasury Regulation Sections 1.704-1(b)(2)(iv) and 1.704-1(b)(4), including adjustments to reflect the allocations to the Members of depreciation, depletion, amortization, and gain or loss as computed for book purposes rather than the allocation of the corresponding items as computed for tax purposes, as required by Treasury Regulation Section 1.704-1(b)(2)(iv)(g). Thus, -4-

the Members' Capital Accounts shall be increased or decreased to reflect a revaluation of the Company's property on its books based on the fair market value of the Company's property on the date of adjustment immediately prior to (A) the contribution of money or other property to the Company by a new or existing Member as consideration for a Membership Interest or an increased Sharing Ratio, (B) the distribution of money or other property by the Company to a Member as consideration for a Membership Interest, or (C) the liquidation of the Company. A Member that has more than one Membership Interest shall have a single Capital Account that reflects all such Membership Interests, regardless of the class of Membership Interests owned by such Member and regardless of the time or manner in which such Membership Interests were acquired. Upon the Disposition of all or a portion of a Membership Interest, the Capital Account of the Disposing Member that is attributable to such Membership Interest shall carry over to the Assignee in accordance with the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv)(l). Within forty-five days following the Closing Date, the Company shall provide Tejas Energy with a written calculation of each Member's Capital Account. 4.05 Deficit Capital Accounts. No Member will be required to pay to the Company, to any other Member or to any third party any deficit balance that may exist from time to time in the Member's Capital Account. ARTICLE 5: DISTRIBUTIONS AND ALLOCATIONS 5.01 Distributions. Subject to Section 6.03, distributions shall be made in such amounts and at such times as shall be determined by the Board of Directors. 5.02 Distributions on Dissolution and Winding Up. Upon the dissolution and winding up of the Company, after adjusting the Capital Accounts for all distributions made under Section 5.01 and all allocations under this Article 5, all available proceeds distributable to the Members as determined under Section 11.02 shall be distributed to all of the Members in amounts equal to the Members' positive Capital Account balances. 5.03 Allocations. (a) For purposes of maintaining the Capital Accounts pursuant to Section 4.04 and for income tax purposes, except as provided in Section 5.03(b), each item of income, gain, loss, deduction and credit of the Company shall be allocated to the Members in accordance with their Sharing Ratios. (b) For income tax purposes, income, gain, loss, and deduction with respect to property contributed to the Company by a Member or revalued pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(f) shall be allocated among the Members in a manner that takes into account the variation between the adjusted tax basis of such property and its book value, as required by Section 704(c) of the Code and Treasury Regulation Section 1.704-1(b)(4)(i), using the remedial allocation method permitted by Treasury Regulation Section 1.704-3(d). 5.04 Varying Interests. All items of income, gain, loss, deduction or credit shall be allocated, and all distributions shall be made, to the Persons shown on the records of the Company -5-

to have been Members as of the last calendar day of the period for which the allocation or distribution is to be made. Notwithstanding the foregoing, if during any taxable year there is a change in any Member's Sharing Ratio, the Members agree that their allocable shares of such items for the taxable year shall be determined based on any method determined by the Board of Directors to be permissible under Code Section 706 and the related Treasury Regulations to take account of the Members' varying Sharing Ratios. ARTICLE 6: MANAGEMENT 6.01 Management. All management powers over the business and affairs of the Company shall be exclusively vested in an Executive Committee (the "Executive Committee") and a Board of Directors (the "Board of Directors") and, subject to the direction of the Executive Committee and the Board of Directors, the Officers. The Officers of the Company shall each constitute a "manager" of the Company within the meaning of the Act and shall have the power and authority to execute documents and instruments in such capacity in the name and on behalf of the Company to the same extent they have such power and authority as Officers of the Company. No Member, by virtue of having the status of a Member, shall have any management power over the business and affairs of the Company or actual or apparent authority to enter into contracts on behalf of, or to otherwise bind, the Company. The authority and functions of the Executive Committee shall be as set forth in Section 6.03. Except as otherwise specifically provided in this Agreement (including Section 6.03(c)), the authority and functions of the Board of Directors on the one hand and of the Officers on the other shall be identical to the authority and functions of the board of directors and officers, respectively, of a corporation organized under the Delaware General Corporation Law. Thus, except as otherwise specifically provided in this Agreement (including Section 6.03(c)), the business and affairs of the Company shall be managed under the direction of the Board of Directors, and the day-to-day activities of the Company shall be conducted on the Company's behalf by the Officers, who shall be agents of the Company. In addition to the powers that now or hereafter can be granted to managers under the Act and to all other powers granted under any other provision of this Agreement and subject to any provisions of this Agreement that require approval of specified individuals or entities prior to the taking of certain actions, the Board of Directors and the Officers (subject to the direction of the Board of Directors) shall have full power and authority to do all things on such terms as they may deem necessary or appropriate to conduct, or cause to be conducted, the business and affairs of the Company, including the following: (a) the making of any expenditures, the lending or borrowing of money, the assumption or guarantee of, or other contracting for, indebtedness and other liabilities, the issuance of evidences of indebtedness and the incurring of any other obligations; (b) the making of tax, regulatory and other filings, or rendering of periodic or other reports to governmental or other agencies having jurisdiction over the business or assets of the Company; (c) the merger or other combination of the Company with or into another entity; -6-

(d) the use of the assets of the Company (including cash on hand) for any purpose consistent with the terms of this Agreement and the repayment of obligations of the Company; (e) the negotiation, execution and performance of any contracts, conveyances or other instruments; (f) the distribution of Company cash; (g) the selection, engagement and dismissal of Officers, employees and agents, outside attorneys, accountants, engineers, consultants and contractors and the determination of their compensation and other terms of employment or hiring; (h) the maintenance of such insurance for the benefit of the Company, as it deems necessary or appropriate; (i) the acquisition or disposition of assets; (j) the formation of, or acquisition of an interest in, or the contribution of property to, any entity; (k) the control of any matters affecting the rights and obligations of the Company, including the commencement, prosecution and defense of actions at law or in equity and otherwise engaging in the conduct of litigation and the incurring of legal expense and the settlement of claims and litigation; and (l) the indemnification of any individual or entity against liabilities and contingencies to the extent permitted by law. 6.02 Board of Directors. (a) Generally. The Board of Directors shall consist of not less than five nor more than nine natural persons. Each Director shall be elected as provided in Section 6.02(b) and shall serve in such capacity until his successor has been elected and qualified or until such Director dies, resigns or is removed. The Board of Directors may determine the number of Directors then constituting the whole Board of Directors, but the Board of Directors shall not decrease the number of persons that constitute the whole Board of Directors if such decrease would shorten the term of any Director, nor may it increase the size during any 12-month period in a manner that would cause the Board of Directors to elect more than two additional Directors to fill the vacancies created by such increase. The Board of Directors as of the date hereof shall consist of nine Directors, consisting of the individuals named below (the last three of which are the initial Tejas Designated Directors, as defined in Section 6.02(b)): -7-

Dan L. Duncan O. S. Andras Randa L. Duncan Gary L. Miller Ralph S. Cunningham Lee W. Marshall, Sr. Charles R. Crisp Curtis R. Frasier Stephen H. McVeigh (b) Election of Directors. Except for Tejas Designated Directors, each member of the Board of Directors shall serve until such member's death, resignation or removal, any Director may be removed at any time, with or without cause, by the Board of Directors, and upon the death, resignation or removal of such Director, such Director's successor shall be elected by the Board of Directors. Pursuant to the Unitholder Rights Agreement, Tejas Energy has the right from time to time as specified therein to appoint members of the Board of Directors. Such designees are referred to herein as "Tejas Designated Directors." So long as Tejas Energy has the continuing right to appoint a Tejas Designated Director pursuant to the Unitholder Rights Agreement, such Director may only be removed by Tejas Energy, and, in the event of the death, resignation or removal of such Director, Tejas Energy shall be entitled to appoint such Director's replacement. If, pursuant to the Unitholder Rights Agreement, Tejas Energy no longer has the right to designate a Tejas Designated Director, then such Director may be removed by the Board of Directors, and the Board of Directors may, notwithstanding Section 6.02(a), decrease the size of the Board of Directors accordingly or appoint such Director's replacement (in the event of removal, resignation or death). (c) Voting; Quorum; Required Vote for Action. Unless otherwise required by the Act, other law or the provisions hereof, (1) each member of the Board of Directors shall have one vote; (2) the presence at a meeting of a majority of the members of the Board of Directors shall constitute a quorum at any such meeting for the transaction of business; and (3) the act of a majority of the members of the Board of Directors present at a meeting at which a quorum is present shall be deemed to constitute the act of the Board of Directors. (d) Meetings. Regular meetings of the Board of Directors shall be held at such times and places as shall be designated from time to time by resolution of the Board of Directors. Notice of such regular meetings shall not be required. Special meetings of the Board of Directors or meetings of any committee thereof may be called by written request of any member of the Board of Directors or a committee thereof on at least 48 hours prior written notice to the other members of the Board of Directors or such committee. Any such notice, or waiver thereof, need not state the purpose of such meeting except as may otherwise be required by law. Attendance of a Director at a meeting (including pursuant to the last sentence of this Section 6.02(d)) shall constitute a waiver of notice -8-

of such meeting, except where such Director attends the meeting for the express purpose of objecting to the transaction of any business on the grounds that the meeting is not lawfully called or convened. Any action required or permitted to be taken at a meeting of the Board of Directors or any committee thereof may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is signed by at least as many members of the Board of Directors or committee thereof as would have been required to take such action at a meeting of the Board of Directors or such committee; provided that, if any such consent has less than the unanimous approval of the members of the Board of Directors or such committee, as applicable, 48 hours prior written notice shall be provided to the non-approving members prior to the taking of such action. Members of the Board of Directors or any committee thereof may participate in and hold a meeting by means of conference telephone, videoconference or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in such meetings shall constitute presence in person at the meeting. (e) Committees. (i) The Board of Directors may appoint one or more committees of the Board of Directors to consist of two or more Directors, which committee(s) shall have and may exercise such of the powers and authority of the Board of Directors with respect to the management of the business and affairs of the Company as may be provided in a resolution of the Board of Directors. Any committee designated pursuant to this Section 6.02(e) shall choose its own chairman, shall keep regular minutes of its proceedings and report the same to the Board of Directors when requested, and, subject to Section 6.02(d), shall fix its own rules or procedures and shall meet at such times and at such place or places as may be provided by such rules or by resolution of such committee or resolution of the Board of Directors. At every meeting of any such committee, the presence of a majority of all the members thereof shall constitute a quorum and the affirmative vote of a majority of the members present shall be necessary for the adoption by it of any resolution. The Board of Directors may designate one or more Directors as alternate members of any committee who may replace any absent or disqualified member at any meeting of such committee; provided, however, that any such designated alternate of the Audit and Conflicts Committee may not be a member, officer, or employee of the Company or a member, officer, director, or employee of any Affiliate of the Company. In the absence or disqualification of a member of a committee, the member or members present at any meeting and not disqualified from voting, whether or not constituting a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of the absent or disqualified member; provided, however, that any such replacement member of the Audit and Conflicts Committee may not be a member, officer, or employee of the Company or a member, officer, director, or employee of any Affiliate of the Company. (ii) In addition to any other committees established by the Board of Directors pursuant to Section 6.02(e)(i), the Board of Directors shall establish an "Audit and Conflicts Committee," which shall be composed entirely of two or more directors who are neither members, officers, nor employees of the Company nor members, officers, directors, or employees of any Affiliate of the Company. The Audit and Conflicts Committee shall be -9-

responsible for approving or disapproving, as the case may be, any matters regarding the business and affairs of the MLP and the OLP required to be considered by, or submitted to, such Audit and Conflicts Committee pursuant to the terms of the MLP Agreement and the Amended and Restated Agreement of Limited Partnership of the OLP, including the review of the external financial reporting of the MLP, the recommendation of independent public accountants to be engaged by the MLP, the review of the MLP's procedures for internal auditing and the adequacy of its internal accounting controls and the approval of any proposed increases in the administrative services fee payable under the EPCO Agreement. (iii) With respect to any committees established by the Board of Directors pursuant to the terms and conditions of this Agreement (other than the Audit and Conflicts Committee and the Executive Committee), Tejas Energy shall be entitled, from time to time during such time as Tejas Energy is, pursuant to the Unitholder Rights Agreement, entitled to designate at least one Director to the Company's Board of Directors, to designate at least one member or representative to serve on each such committee. (f) Chairman. The Board of Directors may elect one of its members as Chairman of the Board (the "Chairman of the Board"). The Chairman of the Board, if any, and if present and acting, shall preside at all meetings of the Board of Directors. Otherwise, the President, if present, acting and a Director, or any other Director chosen by the Board of Directors, shall preside. Unless the Board of Directors provides otherwise, the Chairman of the Board shall be an Officer of the Company and shall have the same power and authority as the President. The Chairman of the Board as of the Closing Date shall be Dan L. Duncan. 6.03 Executive Committee. (a) Generally. The Executive Committee shall consist of five members. The number of members serving on the Executive Committee can only be increased with a unanimous vote of the members of the Executive Committee. Each member of the Executive Committee shall be elected as provided in Section 6.03(b) and shall serve in such capacity until his successor has been elected and qualified or until such member dies, resigns or is removed. The initial members of the Executive Committee are the individuals named below (the last two of which are the initial Tejas Designated Members, as defined in Section 6.03(b)): Dan L. Duncan O. S. Andras Richard H. Bachmann Stephen H. McVeigh Curtis R. Frasier (b) Election of Executive Committee Members. Except for Tejas Designated Members, each member of the initial Executive Committee shall serve until such member's death, resignation or removal, any member of the Executive Committee may be removed at any time, with or without cause, by the Board of Directors, and upon the death, resignation or removal of such member, such member's successor shall be elected by the Board of Directors. Pursuant to the Unitholder Rights Agreement, Tejas Energy has the right from time to time as specified therein to appoint members of the Executive Committee. Such designees are referred to herein as "Tejas Designated Members." -10-

So long as Tejas Energy has the continuing right to appoint a Tejas Designated Member pursuant to the Unitholder Rights Agreement, such member may only be removed by Tejas Energy, and, in the event of the death, resignation or removal of such member, Tejas Energy shall be entitled to appoint such member's replacement. If, pursuant to the Unitholder Rights Agreement, Tejas Energy no longer has the right to designate a Tejas Designated Member, then such member may be removed by the Board of Directors, and the Board of Directors may, notwithstanding Section 6.03(a), decrease the size of the Executive Committee accordingly or appoint such member's replacement (in the event of removal, resignation or death).

The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the Indemnitee acted in a manner contrary to that specified above. Any indemnification pursuant to this Section 6.06 shall be made only out of the assets of the Company. -14-

(b) To the fullest extent permitted by law, expenses (including reasonable legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 6.06(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined in a judicial proceeding or a binding arbitration that the Indemnitee is not entitled to be indemnified as authorized in this Section 6.06.

(f) An Indemnitee shall not be denied indemnification in whole or in part under this Section 6.06 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. (g) The provisions of this Section 6.06 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other persons.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Company or any other person or entity for losses sustained or liabilities incurred as a result of any act or omission constituting a breach of such Indemnitee's fiduciary duty if such Indemnitee acted in good faith.

(c) Any amendment, modification or repeal of this Section 6.06 or any provision hereof shall be prospective only and shall not in any way affect the limitations on liability under this Section 6.06 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may be asserted.

The Members agree that a breach of the provisions of this Section 9.01 may cause irreparable injury to the Company and to the other Members for which monetary damages (or other remedy at law) are inadequate in view of (i) the complexities and uncertainties in measuring the actual damages that would be sustained by reason of the failure of a Member to comply with such provision and (ii) the uniqueness of the Company business and the relationship among the -18-

Members. Accordingly, the Members agree that the provisions of this Section 9.01 may be enforced by specific performance. (b) Dispositions of Membership Interests. (i) General Restriction. A Member may not Dispose of its Membership Interest except by complying with all of the following requirements: (A) such Member must receive the consent of the other Members, which consent shall not be unreasonably withheld; provided that nothing herein shall restrict the ability of Tejas Energy to transfer its Membership Interest to a Permitted Affiliate or the ability of EPC II and DDLLC to transfer their respective Membership Interests to a Duncan Permitted Affiliate; and (B) such Member must comply with the requirements of Section 9.01(b)(iii) and, if the Assignee is to be admitted as a Member, Section 9.01(b)(ii). (ii) Admission of Assignee as a Member. An Assignee has the right to be admitted to the Company as a Member, with the Membership Interest (and attendant Sharing Ratio) so transferred to such Assignee, only if (A) the Disposing Member making the Disposition has granted the Assignee either (1) the Disposing Member's entire Membership Interest or (2) the express right to be so admitted; and (B) such Disposition is effected in strict compliance with this Section 9.01. (iii) Requirements Applicable to All Dispositions and Admissions. In addition to the requirements set forth in Sections 9.01(b)(i) and 9.01(b)(ii), any Disposition of a Membership Interest and any admission of an Assignee as a Member shall also be subject to the following requirements, and such Disposition (and admission, if applicable) shall not be effective unless such requirements are complied with; provided, however, that the Board of Directors, in its sole and absolute discretion, may waive any of the following requirements: (A) Disposition Documents.

(iv) Clarification Regarding Transfer of Equity Interests in Members.

(c) Encumbrances of Membership Interest. A Member may not Encumber its Membership Interest except by complying with both of the following requirements: (i) such Member must receive the consent of the other Member, which consent may be granted or withheld in the sole discretion of such other Member; and (ii) the instrument creating such Encumbrance must provide that any foreclosure of such Encumbrance (or Disposition in lieu of such foreclosure) must comply with the requirements of Section 9.01(b). 9.02 Transfer of Tejas Energy Rights.

In the event of a Disposition by EPC II to a Duncan Permitted Affiliate of all or part of its interest in the Company (the "EPC II Transferred Interest") in accordance with the terms and conditions of this Agreement, EPC II may transfer to such Duncan Permitted Affiliate the rights of EPC II under this Agreement relating to the EPC II Transferred Interest; provided that such Duncan Permitted Affiliate shall agree to be bound by (i) the terms and conditions of the Unitholder Rights Agreement to the same extent as EPC II was bound with respect to the EPC II Transferred Interest (including, without limitation, Section 2.3(b)) and (ii) Section 6.13(a) and (b) of the Contribution Agreement to the same extent as EPC II was bound with respect to the EPC II Transferred Interest, and shall execute an assignment in the form required by Section 9.01(b)(iii).

managers, members, partners, trustees, beneficiaries, or other applicable Persons necessary for the due authorization, execution, delivery, and performance of this Agreement by that Member have been duly taken; (b) that Member has duly executed and delivered this Agreement and the other documents contemplated herein, and they constitute the legal, valid and binding obligation of that Member enforceable against it in accordance with their terms (except as may be limited by bankruptcy, insolvency or similar Laws of general application and by the effect of general principles of equity, regardless of whether considered at law or in equity); and (c) that Member's authorization, execution, delivery, and performance of this Agreement does not and will not (i) conflict with, or result in a breach, default or violation of, (A) the organizational documents of such Member, (B) any contract or agreement to which that Member is a party or is otherwise subject, or (C) any Law, order, judgment, decree, writ, injunction or arbitral award to which that Member is subject; or (ii) require any consent, approval or authorization from, filing or registration with, or notice to, any Governmental Authority or other Person, unless such requirement has already been satisfied. ARTICLE 11: DISSOLUTION, WINDING-UP AND TERMINATION 11.01 Dissolution.

(a) On the occurrence of a Dissolution Event, unless a Continuation Election has been made, the Board of Directors shall appoint a liquidator. The liquidator shall proceed diligently to wind up the affairs of the Company and make final distributions as provided herein and in the Act. The costs of winding up shall be borne as a Company expense. Until final distribution, the liquidator shall continue to operate the Company properties with all of the power and authority of the Members. The steps to be accomplished by the liquidator are as follows: -21-

(i) as promptly as possible after dissolution and again after final winding up, the liquidator shall cause a proper accounting to be made of the Company's assets, liabilities, and operations through the last calendar day of the month in which the dissolution occurs or the final winding up is completed, as applicable; (ii) the liquidator shall discharge from Company funds all of the indebtedness and other debts, liabilities and obligations of the Company (including all expenses incurred in winding up and any loans described in Section 4.01) or otherwise make adequate provision for payment and discharge thereof (including the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the liquidator may reasonably determine); and (iii) all remaining assets of the Company shall be distributed to the Members as follows: (A) the liquidator may sell any or all Company property, including to Members, and any resulting gain or loss from each sale shall be computed and allocated to the Capital Accounts of the Members in accordance with the provisions of Article 5; (B) with respect to all Company property that has not been sold, the fair market value of that property shall be determined and the Capital Accounts of the Members shall be adjusted to reflect the manner in which the unrealized income, gain, loss, and deduction inherent in property that has not been reflected in the Capital Accounts previously would be allocated among the Members if there were a taxable disposition of that property for the fair market value of that property on the date of distribution; and (C) Company property (including cash) shall be distributed among the Members in accordance with Section 5.02; and those distributions shall be made by the end of the taxable year of the Company during which the liquidation of the Company occurs (or, if later, 90 Days after the date of the liquidation). (b) The distribution of cash or property to a Member in accordance with the provisions of this Section 11.02 constitutes a complete return to the Member of its Capital Contributions and a complete distribution to the Member of its Membership Interest and all the Company s property and constitutes a compromise to which all Members have consented pursuant to Section 18-502(b) of the Act.

This Agreement (together with the Unitholder Rights Agreement) constitutes the entire agreement of the Members and their Affiliates relating to the Company and the transactions contemplated hereby and supersedes all provisions and concepts contained in all prior contracts or agreements between the Members or any of their Affiliates with respect to the Company and the transactions contemplated hereby, whether oral or written. 12.04 Effect of Waiver or Consent. Except as otherwise provided in this Agreement, a waiver or consent, express or implied, to or of any breach or default by any Member in the performance by that Member of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Member of the same or any other obligations of that Member with respect to the Company. Except as otherwise provided in this Agreement, failure on the part of a Member to complain of any act of any Member or to declare any Member in default with respect to the Company, irrespective of how long that failure continues, does not constitute a waiver by that Member of its rights with respect to that default until the applicable statute-of-limitations period has run. 12.05 Amendment or Restatement. This Agreement or the Delaware Certificate may be amended or restated only by a written instrument executed (or, in the case of the Delaware Certificate, approved) by all Members. -23-

THIS AGREEMENT IS GOVERNED BY AND SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, EXCLUDING ANY CONFLICT-OF-LAWS RULE OR PRINCIPLE THAT MIGHT REFER THE GOVERNANCE OR THE CONSTRUCTION OF THIS AGREEMENT TO THE LAW OF ANOTHER JURISDICTION. In the event of a direct conflict between the provisions of this Agreement and any mandatory, non-waivable provision of the Act, such provision of the Act shall control. If any provision of the Act provides that it may be varied or superseded in a limited liability company agreement (or otherwise by agreement of the members or managers of a limited liability company), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter. If any provision of this Agreement or the application thereof to any Member or circumstance is held invalid or unenforceable to any extent, (a) the remainder of this Agreement and the application of that provision to other Members or circumstances is not affected thereby, and (b) the Members shall negotiate in good faith to replace that provision with a new provision that is valid and enforceable and that puts the Members in substantially the same economic, business and legal position as they would have been in if the original provision had been valid and enforceable. 12.08 Further Assurances. In connection with this Agreement and the transactions contemplated hereby, each Member shall execute and deliver any additional documents and instruments and perform any additional acts that may be necessary or appropriate to effectuate and perform the provisions of this Agreement and those transactions. 12.09 Waiver of Certain Rights. Each Member irrevocably waives any right it may have to maintain any action for dissolution of the Company or for partition of the property of the Company. 12.10 Counterparts.

The Company may borrow under either the Working Capital Revolving Credit Commitment or the Investment Revolving Credit Commitment during the Commitment Period on any Working Day if the borrowing is a Eurodollar Loan or on any Business Day if the borrowing is an Alternate Base Rate Loan; provided that the Company shall give the Agent irrevocable notice (which notice must be received by the Agent prior to 10:00 A.M., New York City time) (a) three Working Days prior to the requested borrowing date, in the case of Eurodollar Loans and (b) one Business Day prior to the requested borrowing date, in the case of Alternate Base Rate Loans, specifying (i) the amount to be borrowed, (ii) the requested borrowing date, (iii) whether the borrowing is to be Working Capital Revolving Credit Loans or Investment Revolving Credit Loans, (iv) whether the borrowing is to be a Eurodollar Loan, an Alternate Base Rate Loan or a combination thereof and (v) if the loan is to be entirely or partly a Eurodollar Loan, the length of the Interest Period for such Eurodollar Loan.

Proceeds of Revolving Credit Loans received by the Agent shall be made available to the Company at the office of the Agent specified in subsection 11.1 by crediting the Company's account on the books of such office with the aggregate of the amounts made available to the Agent by the Banks and in like funds as received by the Agent. 2.4 Termination, Reduction or Extension of Revolving Credit Commitments . (a) The Company shall have the right, upon not less than five Business Days' notice to the Agent, to terminate the Revolving Credit Commitments or, from time to time, reduce the amount of the Revolving Credit Commitments. Any such reduction shall be ratable among the Working Capital Revolving Credit Commitments and the Investment Revolving Credit Commitments and no such reduction shall be permitted to be an amount which is less than the aggregate principal amount of the Working Capital Revolving Credit Loans, in the case of a reduction of the Working Capital Revolving Credit Commitments, or the Investment Revolving Credit Loans, in the case of a reduction of the Investment Revolving Credit Commitments, then outstanding after giving effect to any contemporaneous prepayment thereof. Upon receipt of such notice the Agent shall promptly notify each Bank thereof. Any termination of the Revolving Credit Commitments shall be accompanied by prepayment in full of the Revolving Credit Loans, together with accrued interest thereon to the date of such prepayment. Any reduction of the Working Capital Revolving Credit Commitments or the Investment Revolving Credit Commitments (other than as a result of any mandatory prepayment) shall be in the amount of $1,000,000 or any whole multiple of $500,000 in excess thereof and shall reduce permanently the amount of the Working Capital Revolving Credit Commitments or the Investment Revolving Credit Commitments, as the case may be, then in effect. The Revolving Credit Commitments once terminated or reduced may not be reinstated. (b) The Company may on any day which is at least 60 and not more than 90 days prior to the Revolving Credit Commitment Termination Date in effect at such time request by notice to the Agent and the Banks that the Revolving Credit Commitment Termination Date be extended for an additional 364 day period beginning on the Revolving Credit Commitment Termination Date then in effect. No more than 30 days after receipt of any such extension request, each Bank shall notify the Agent of its decision with respect thereto (as to which decision the Agent shall promptly notify the Company). The Revolving Credit Commitment Termination Date shall be so extended provided that (i) no Default or Event of Default shall have occurred and is continuing at such time and (ii) the Company shall have received the prior written consent of all the Banks for such extension. SECTION 3. LETTERS OF CREDIT 3.1 Letter of Credit Commitments . Subject to the terms and conditions hereof, the Agent, on behalf of the Banks, and in reliance on the agreement of the Banks set forth in subsection 3.3, agrees to issue Commercial Letters of Credit and Standby Letters of Credit for the account of the Company on any Business Day from and including the Closing Date to but not including the Revolving Credit Commitment Termination Date (as the same may have been extended at the time of issuance); provided that the Agent shall have no obligation to issue any Letter of Credit if, after giving effect to such issuance, (i) the aggregate amount of the Available Investment Revolving Credit Commitments would be less than zero or (ii) the Aggregate L/C Outstandings shall exceed $10,000,000 until such time as all obligations under the Existing Credit Agreement have been fully and finally paid in full and all commitments by the Lenders hereunder have been finally terminated and thereafter, $40,000,000. 3.2 Issuance and Continuation of Letters of Credit. (a) The Company may request the Agent to issue a Commercial Letter of Credit or a Standby Letter of Credit for its account by delivering to the Agent at least four Business Days prior to the proposed date of issuance at its address specified in subsection 11.1, an Application setting forth in such Application (i) the proposed issuance date of such Letter of Credit, (ii) the face amount of such Letter of Credit and (iii) such other information as may be requested in such Application. The Company shall also provide such other certificates, documents and other papers and information as the Agent may reasonably request. Upon receipt of such Application, the Agent will notify each other Bank thereof and shall, subject to the terms and conditions hereof, promptly open such Letter of Credit by issuing the original of such Letter of Credit to the beneficiary thereof and by furnishing a copy thereof to the Company. (b) Each Commercial Letter of Credit and Standby Letter of Credit issued hereunder shall, among other things, (i) be denominated in Dollars, (ii) provide for the payment of sight drafts when presented for honor thereunder in accordance with the terms thereof and when accompanied by the certificate described therein, (iii) have an expiry date occurring not later than the Revolving Credit Commitment Termination Date, (iv) not provide for its automatic extension beyond such expiry date, (v) be in form and substance satisfactory to the Agent and (vi) be issued to a beneficiary reasonably satisfactory to the Agent. 3.3 Participating Interests . Effective in the case of each Letter of Credit as of the date of the opening thereof, each Bank severally agrees that it shall be (or shall continue to be) unconditionally and irrevocably liable, without regard to the occurrence of any Default or Event of Default, to the extent of such Bank's Commitment Percentage, to reimburse the Agent on demand for the amount of each draft paid by the Agent under such Letter of Credit to the extent that such amount is not reimbursed by the Company pursuant to subsection 3.4. Each such payment made by a Bank shall be treated as the purchase by such Bank of a participating interest in such Company's Reimbursement Obligation under subsection 3.4 in an amount equal to such payment. Each Bank shall share on a pro rata basis (calculated by reference to its participating interest from time to time in such Reimbursement Obligations) in any interest which accrues pursuant to subsection 3.4. All amounts recovered by the Agent or any Bank hereunder or under the other Loan Documents and which are applied to the Reimbursement Obligations under subsection 3.4 shall be distributed to the Banks in an amount equal to their respective pro rata shares thereof (calculated as provided in the preceding sentence). 3.4 Reimbursement Obligation of the Company. In order to induce the Agent to issue (or continue, as the case may be) the Letters of Credit and the Banks to participate therein, the Company hereby agrees to reimburse the Agent (a) unless such Reimbursement Obligation has been accelerated pursuant to Section 8, on each date on which the Agent notifies the Company of the date and amount of a draft presented under any Letter of Credit issued for its respective account and paid by the Agent, for (i) the amount of such draft paid by the Agent on behalf of the Banks under such Letter of Credit and (ii) the amount of any taxes, fees, charges or other costs or expenses whatsoever incurred by the Agent or any Bank in connection with any payment made by the Agent or any Bank under, or with respect to, such Letter of Credit and (b) upon the acceleration of such Reimbursement Obligation in accordance with subsection 8.2, for an amount equal to the then maximum liability (whether direct or contingent) of the Agent and the Banks under such Letter of Credit. Each such payment shall be made to the Agent at the office of the Agent specified in subsection 11.1, in lawful money of the United States of America and in immediately available funds. Interest on any and all amounts remaining unpaid by the Company under this subsection 3.4 from the date such amounts become payable (whether at stated maturity, by acceleration or otherwise) until payment in full shall be payable on demand of the Agent at the fluctuating rate per annum equal to 2% above the Alternate Base Rate. 3.5 Letter of Credit Payments. If any draft shall be presented for payment under any Letter of Credit, the Agent shall promptly notify the Company of the date and the amount of the draft presented for payment. If the Company fails to reimburse the Agent as provided in subsection 3.4 by the close of business on the date each such draft is paid by the Agent, the Agent shall promptly notify each Bank thereof and of the date, the amount of the draft paid and such Bank's ratable share thereof. No later than the close of business on the date such notice is given, each Bank shall make available to the Agent, at its office specified in subsection 11.1, in immediately available funds, such Bank's ratable share of such draft. The responsibility of the Agent to the Company and the Banks shall be only to determine that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment shall be in conformity with such Letter of Credit. If any Bank's ratable share of a draft presented for payment under any Letter of Credit is made available to the Agent on a date after the date such draft is paid by the Agent, such Bank shall pay to the Agent on demand an amount equal to the product of (i) the daily average Federal Funds Effective Rate during such period as quoted by the Agent, times (ii) the amount of such Bank's Commitment Percentage of such draft, times (iii) a fraction the numerator of which is the number of days that elapse from and including the date such draft is paid by the Agent to the date on which such Bank's Commitment Percentage of such draft shall have become immediately available to the Agent and the denominator of which is 360. A certificate of the Agent submitted to any Bank with respect to any amounts owing under this subsection 3.6 shall be conclusive, absent manifest error. If such Bank's Commitment Percentage is not in fact made available to the Agent by such Bank within three Business Days of the date such draft is paid by the Agent, the Agent shall be entitled to recover such amount with interest thereon at the rate per annum applicable to Alternate Base Rate Loans hereunder, on demand, from the Company. 3.6 Increased Costs. If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Bank with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof shall either (i) impose, modify, assess or deem applicable any reserve, special deposit, assessment or similar requirement against letters of credit issued by the Agent or (ii) impose on the Agent or any Bank any other condition regarding any Letter of Credit, and the result of any event referred to in clauses (i) or (ii) above shall be to increase the cost to the Agent or any Bank of issuing or maintaining such Letter of Credit, or its participation therein, as the case may be (which increase in cost shall be the result of the Agent or any Bank's reasonable allocation of the aggregate of such cost increases resulting from such events), then, upon demand by the Agent or such Bank, the Company shall promptly pay to the Agent or such Bank from time to time as specified by the Agent or such Bank additional amounts which shall be sufficient to compensate the Agent or such Bank for such increased cost, together with interest on each such amount from the date demanded until payment in full thereof at the rate provided in subsection 3.4. A certificate as to the fact and amount of such increased cost incurred by the Agent or such Bank as a result of any event showing in reasonable detail the basis for the calculation thereof submitted by the Agent or any Bank to the Company, shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Revolving Credit Loans and all other amounts payable hereunder. 3.7 Nature of Obligations; Indemnities. (a) The obligations of the Company hereunder shall be absolute and unconditional under any and all circumstances and irrespective of any set off, counterclaim or defense to payment which the Company may have or had against the Agent, any Bank or any beneficiary of a Letter of Credit, provided, however, that this provision shall be deemed a waiver by the Company of the assertion of a compulsory counterclaim only to the extent permitted by applicable law. The Company assumes all risks of the acts or omissions of the users of the Letters of Credit. Neither the Agent nor any Bank nor any of their respective correspondents shall be responsible: (i) for the form, validity, sufficiency, accuracy, genuineness or legal effect of any document specified in any of the applications for any of the Letters of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent, or forged; (ii) for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any of the Letters of Credit or any of the rights or benefits thereunder or proceeds thereof in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) for failure of any draft to bear any reference or adequate reference to any of the Letters of Credit, or failure of anyone to note the amount of any draft on the reverse of any of the Letters of Credit or to surrender or to take up any of the Letters of Credit or to send forward any such document apart from drafts as required by the terms of any of the Letters of Credit, each of which provisions, if contained in a Letter of Credit itself, it is agreed, may be waived by the Agent; (iv) for errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (v) for any error, neglect, default, suspension or insolvency of any correspondents of the Agent; (v) for errors in translation or for errors in interpretation of technical terms; (vii) for any loss or delay, in the transmission or otherwise, of any such document or draft or of proceeds thereof; (viii) for any misapplication by any beneficiary of any Letter of Credit of the proceeds of a drawing of such Letter of Credit; or (ix) for any other circumstances whatsoever in making or failing to make payment under a Letter of Credit, except only that the Company shall have a claim against the Agent, and the Agent shall be liable to the Company, to the extent, but only to the extent, of any direct, as opposed to consequential, damages suffered by the Company which the Company proves were caused by the Agent's willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit. None of the above shall affect, impair or prevent the vesting of any of the rights or powers of the Agent or any Bank. The Agent shall have the right to transmit the terms of the Letter of Credit involved without translating them. (b) In furtherance and extension and not in limitation of the specific provisions hereinabove in this Section 3 set forth, (i) any action taken or omitted by the Agent or by any of its correspondents under or in connection with any of the Letters of Credit, if taken or omitted in good faith, shall be binding upon the Company and shall not put the Agent or its correspondents under any resulting liability to the Company and (ii) the Agent may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary; provided that if the Agent shall receive written notification from both the beneficiary of a Letter of Credit and the Company that sufficiently identifies (in the opinion of the Agent) documents to be presented to the Agent which are not to be honored, the Agent agrees that it will not honor such documents. (c) The Company hereby agrees at all times to protect, indemnify and save harmless each of the Agent, the Banks or their respective correspondents from and against any and all claims, actions, suits and other legal proceedings, and from and against any and all losses, claims, demands, liabilities, damages, costs, charges, counsel fees and other expenses which they or any of them may, at any time, sustain or incur by reason of or in consequence of or arising out of the issuance of any of the Letters of Credit, except for losses and expenses which the Company proves were caused by the willful misconduct or gross negligence of an indemnified party; it being the intention of the parties that this agreement shall be construed and applied to protect and indemnify each of the Agent, the Banks and their respective correspondents against any and all risks involved in the issuance of all of the Letters of Credit or participations therein, all of which risks, whether or not foreseeable, being hereby assumed by the Company, including, without limitation, any and all risks of all acts by any Governmental Authority, domestic or foreign. The Agent and the Banks shall not, in any way, be liable for any failure by the Agent or anyone else to pay a draft drawn under any of the Letters of Credit as a result of any acts, whether rightful or wrongful, of any Governmental Authority, or any other cause not readily within their control or the control of their respective correspondents, agents, or subagents. Without limiting the generality of the foregoing, the Company shall reimburse the Agent and the Banks and their respective correspondents and shall pay and indemnify the Agent, any Banks or its correspondents against payment of, out-of-pocket costs and expenses, withholding taxes, liabilities and damages (including, without limitation, reasonable counsel fees) incurred or sustained by any of them in connection with any of the Letters of Credit or by reason of any such failure to pay. Also, without limiting the generality of the foregoing, the Company shall be responsible for, and shall reimburse the Agent and the Banks forthwith upon its receipt of any demand therefor, any and all commissions, fees and other charges paid or payable by the Agent or any Bank to any foreign bank which shall be an advising bank or a beneficiary of a Letter of Credit which shall, in reliance thereon, have issued its own letter of credit in respect of obligations of the Company. 3.8 Purpose of the Letters of Credit .

The Company may elect from time to time to convert Alternate Base Rate Loans to Eurodollar Loans by giving the Agent at least five Working Days' prior irrevocable notice of such election. Upon receipt of such notice, the Agent shall promptly notify each Bank thereof. Promptly following the date on which such conversion is being made each Bank shall take such action as is necessary to transfer its portion of such Loans to its Domestic Lending Office or its Eurodollar Lending Office, as the case may be. All or any part of outstanding Eurodollar Loans and Alternate Base Rate Loans may be converted as provided herein, provided that (i) no Revolving Credit Loan may be converted into a Eurodollar Loan when any Default or Event of Default has occurred and is continuing, (ii) partial conversions shall be in an aggregate principal amount of $1,000,000 or a whole multiple of $500,000 in excess thereof and (iii) any such conversion may only be made if, after giving effect thereto, subsection 4.5 shall not have been contravened. (b) Any Eurodollar Loans may be continued as such upon the expiration of an Interest Period with respect thereto by compliance by the Company thereof with the notice provisions contained in subsection 4.4(a); provided that no Eurodollar Loan may be continued as such when any Default or Event of Default has occurred and is continuing, but shall be automatically converted to an Alternate Base Rate Loan on the last day of the then current Interest Period with respect thereto. The Agent shall notify the Banks promptly that such automatic conversion contemplated by this subsection 4.4(b) will occur. 4.5 Minimum Amounts of Eurodollar Tranches . All borrowings, conversions, payments, prepayments and selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, after giving effect thereto, (a) the aggregate principal amount of the Eurodollar Loans comprising any Eurodollar Tranche shall not be less than $1,000,000 and (b) there shall be no more than 15 Eurodollar Tranches of Revolving Credit Loans at any one time outstanding. 4.6 Interest Rate, Payment Dates and Lending Offices . (a) The Revolving Credit Loans comprising each Eurodollar Tranche shall bear interest for each Interest Period with respect thereto on the unpaid principal amount thereof at a rate per annum equal to the Eurodollar Rate determined for such Interest Period plus the Applicable Margin. (b) Alternate Base Rate Loans shall bear interest for the period from and including the date thereof until maturity on the unpaid principal amount thereof at a rate per annum equal to the Alternate Base Rate plus the Applicable Margin. (c) If all or a portion of the principal amount of any of the Revolving Credit Loans shall not be paid when due (whether at the stated maturity, by acceleration or otherwise) each Eurodollar Loan shall be converted to an Alternate Base Rate Loan at the end of the last Interest Period with respect thereto. Any such overdue principal amount shall bear interest at a rate per annum which is 2% above the rate which would otherwise be applicable pursuant to subsection 4.6 (a) or (b) from the date of such non-payment until paid in full (as well after as before judgment). (d) Interest shall be payable in arrears on each Interest Payment Date. If all or any portion of interest due on any of the Revolving Credit Loans shall not be paid when due (whether at the stated maturity, by acceleration or otherwise) or if all or any portion of any fee due in connection with this Agreement or any of the Revolving Credit Loans shall not be paid when due, then any such overdue amount shall bear interest at a rate per annum which is 2% above the Alternate Base Rate plus the Applicable Margin from the date of such non-payment until paid in full (as well as after as before judgment). (e) Eurodollar Loans shall be made and maintained by each Bank at its Eurodollar Lending Office, and Alternate Base Rate Loans shall be made and maintained by each Bank at its Domestic Lending Office. 4.7 Computation of Interest and Fees . (a) Interest in respect of Alternate Base Rate Loans, commitment fees and interest on overdue interest, commitment fees and other amounts payable hereunder shall be calculated on the basis of a 365 (or 366, as the case may be) day year for the actual days elapsed. Interest in respect of Eurodollar Loans shall be calculated on the basis of a 360 day year for the actual days elapsed. The Agent shall as soon as practicable notify the Company and the Banks of each determination of a Eurodollar Rate. Any change in the interest rate on a Revolving Credit Loan resulting from a change in the Alternate Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change in the Alternate Base Rate is announced, or such change in the Eurocurrency Reserve Requirements shall become effective, as the case may be. The Agent shall as soon as practicable notify the Company and the Banks of the effective date and the amount of each such change. (b) Each determination of an interest rate by the Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Company and the Banks in the absence of manifest error. The Agent shall, at the request of the Company, deliver to the Company a statement showing the quotations used by the Agent in determining any interest rate pursuant to subsection 4.6(a). 4.8 Inability to Determine Interest Rate . In the event that: (i) the Agent shall have determined (which determination shall be conclusive and binding upon the Company) that, by reason of circumstances affecting the interbank eurodollar market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for any requested Interest Period; or (ii) the Agent shall have received notice prior to the first day of such Interest Period from Banks constituting the Required Banks that the interest rate determined pursuant to subsection 4.6(a) for such Interest Period does not accurately reflect the cost to such Banks (as conclusively certified by such Banks) of making or maintaining its affected Revolving Credit Loan during such Interest Period, with respect to (a) proposed Revolving Credit Loans that the Company has requested be made as Eurodollar Loans, (b) Eurodollar Loans that will result from the requested conversion of Alternate Base Rate Loans into Eurodollar Loans or (c) the continuation of Eurodollar Loans beyond the expiration of the then current Interest Period with respect thereto, the Agent shall forthwith give telex or telephonic notice of such determination to the Company and the Banks at least one day prior to, as the case may be, the requested Borrowing Date for such Eurodollar Loans, the conversion date of such Domestic Dollar Loans or the last day of such Interest Period. If such notice is given (x) any requested Eurodollar Loans shall be made as Alternate Base Rate Loans, (y) any Alternate Base Rate Loans that were to have been converted to Eurodollar Loans shall be continued as Alternate Base Rate Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then current Interest Period with respect thereto, to Alternate Base Rate Loans. Until such notice has been withdrawn by the Agent, no further Eurodollar Loans shall be made, nor shall the Company have the right to convert Alternate Base Rate Loans to Eurodollar Loans. 4.9 Pro Rata Treatment and Payments . (a) Each borrowing by the Company from the Banks, each payment by the Company on account of any commitment fee hereunder and any reduction of the Revolving Credit Commitments of the Banks hereunder shall be made pro rata according to the respective Commitment Percentages of the Banks. Each payment (including each prepayment) by the Company on account of principal of and interest on the Working Capital Revolving Credit Loans or the Investment Revolving Credit Loans shall be made pro rata according to the respective outstanding principal amounts of the Working Capital Revolving Credit Loans or the Investment Revolving Credit Loans, as the case may be, held by each Bank. All payments (including prepayments) to be made by the Company on account of principal, interest and fees shall be made without set-off or counterclaim and shall be made to the Agent, for the account of the Banks, at the Agent's office set forth in subsection 11.1, in lawful money of the United States of America and in immediately available funds. The Agent shall distribute such payments to the Banks promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day, and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Working Day, the maturity thereof shall be extended to the next succeeding Working Day unless the result of such extension would be to extend such payment into another calendar month in which event such payment shall be made on the immediately preceding Working Day. (b) Unless the Agent shall have been notified in writing by any Bank prior to a Borrowing Date that such Bank will not make the amount which would constitute its Commitment Percentage of the borrowing on such date available to the Agent, the Agent may assume that such Bank has made such amount available to the Agent on such Borrowing Date, and the Agent may, in reliance upon such assumption, make available to the Company a corresponding amount. If such amount is made available to the Agent on a date after such Borrowing Date, such Bank shall pay to the Agent on demand an amount equal to the product of (i) the daily average Federal Funds Effective Rate during such period, times (ii) the amount of such Bank's Commitment Percentage of such borrowing, times (iii) a fraction the numerator of which is the number of days that elapse from and including such Borrowing Date to the date on which such Bank's Commitment Percentage of such borrowing shall have become immediately available to the Agent and the denominator of which is 360. A certificate of the Agent submitted to any Bank with respect to any amounts owing under this subsection 4.9(b) shall be conclusive, absent manifest error. If such Bank's Commitment Percentage is not in fact made available to the Agent by such Bank within three Business Days of such Borrowing Date, the Agent shall be entitled to recover such amount with interest thereon at the rate per annum applicable to Alternate Base Rate Loans hereunder, on demand, from the Company. 4.10 Illegality . Notwithstanding any other provisions herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Bank to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Bank hereunder to make Eurodollar Loans or convert Alternate Base Rate Loans to Eurodollar Loans shall forthwith be canceled and (b) such Bank's Revolving Credit Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to Alternate Base Rate Loans on the respective next succeeding Interest Payment Date(s) for such Revolving Credit Loans or within such earlier period as required by law. If any such prepayment or conversion of a Eurodollar Loan occurs on a day which is not the last day of the current Interest Period with respect thereto, the Company shall pay to such Bank such amounts, if any, as may be required pursuant to subsection 4.13. 4.11 Requirements of Law . (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Bank with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof: (i) does or shall subject any Bank to any tax of any kind whatsoever with respect to this Agreement, any Revolving Credit Note or any Eurodollar Loans made by it, or change the basis of taxation of payments to such Bank of principal, commitment fee, interest or any other amount payable hereunder (except for changes in the rate of tax on the overall net income of such Bank); (ii) does or shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against (A) assets held by, or deposits or other liabilities in or for the account of, advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of such Bank which are not otherwise included in the determination of the Eurodollar Rate hereunder or (B) Letters of Credit issued by the Agent or participated in by the Banks; (iii) does or shall impose on such Bank any other condition; and the result of any of the foregoing is to increase the cost to (A) any Bank, by any amount which such Bank deems to be material, of making, renewing or maintaining advances or extensions of credit or to reduce any amount receivable hereunder, in each case, in respect to its Eurodollar Loans, or (B) the Agent or any Bank of issuing or maintaining Letters of Credit (or its participation therein, as the case may be), or to reduce any amount receivable in connection therewith, then, in any such case, upon demand by the Agent or such Bank (with a copy to the Agent), the Company shall promptly pay to the Agent or such Bank, as the case may be, any additional amounts necessary to compensate the Agent or such Bank for such additional cost or reduced amount receivable, together with interest on each such amount from the date demanded until payment in full thereof at the rate provided in subsection 4.6(c) (in the case of increased costs in respect of Eurodollar Loans) or subsection 3.5 (in the case of increased costs in respect of Letters of Credit). If the Agent or a Bank becomes entitled to claim any additional amounts pursuant to this subsection, it shall promptly notify the Company, through the Agent, of the event by reason of which it has become so entitled. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by the Agent or such Bank, through the Agent, to the Company shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and payment of the outstanding Revolving Extensions of Credit. Each Bank will promptly notify the Company and the Agent of any event described in this subsection 4.11 of which it has knowledge and will designate a different Eurodollar Lending Office if such designation will avoid the need for, or reduce the amount of, compensation as described in this subsection 4.11 and will not be otherwise disadvantageous to such Bank. If any Bank demands compensation from the Company pursuant to this subsection 4.11 the Company may, upon at least three Business Days' prior notice to such Bank through the Agent, prepay in full the then outstanding Eurodollar Loans of such Bank, as the case may be, together with accrued interest thereon to the date of prepayment and, concurrently therewith, borrow from such Bank Alternate Base Rate Loans, in principal amounts equal to the aggregate principal amounts of such Loans being prepaid and with the same maturities, and such Bank shall make such Alternate Base Rate Loans. If any prepayment or conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Company shall pay to such Bank such amounts, if any, as may be required pursuant to subsection 4.13. (b) In the event that any Bank shall have determined that the adoption of any law, rule or regulation regarding capital adequacy, or any change therein or in the interpretation or application thereof or compliance by any Bank or any corporation controlling such Bank with any request or directive regarding capital adequacy (whether or not having the force of law) from any central bank or Governmental Authority, does or shall have the effect of reducing the rate of return on such Bank's or corporation's capital as a consequence of such Bank's obligations hereunder to a level below that which such Bank or corporation could have achieved but for such Requirement of Law, change or compliance (taking into consideration such Bank's or corporation's policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within fifteen days after submission by such Bank or corporation to the Company (with a copy to the Agent) of a written request therefor, the Company shall pay to such Bank such additional amount or amounts as will compensate such Bank or corporation for such reduction. The agreements in this subsection 4.11(b) shall survive the termination of this Agreement and the payment of the Revolving Extensions of Credit and all other amounts payable hereunder. 4.12 Taxes . (a) All payments made by the Company under this Agreement shall be made free and clear of, and without reduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority excluding, in the case of the Agent and each Bank, net income and franchise taxes (or taxes imposed in lieu of net income or franchise taxes) imposed on (or measured by) the income or profits of the Agent or such Bank by the jurisdiction under the laws of which the Agent or such Bank is organized or any political subdivision or taxing authority thereof or therein or by any jurisdiction in which such Bank's Domestic Lending Office or Eurodollar Lending Office, as the case may be, is located or any political subdivision or taxing authority thereof or therein or by any other jurisdiction (or political subdivision or taxing authority thereof or therein) as a result of a connection between such Bank and such jurisdiction (or political subdivision or taxing authority thereof or therein) other than a connection resulting solely from entering into this Agreement (all such non-excluded taxes, levies, imposts, deductions, charges or withholdings being hereinafter called "Taxes"). If any Taxes are required to be withheld from any amounts payable to the Agent or any Bank hereunder, the amounts so payable to the Agent or such Bank shall be increased to the extent necessary to yield to the Agent or such Bank (after payment of all Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement. Whenever any Taxes are payable by the Company, as promptly as possible thereafter, the Company shall send to the Agent for its own account or for the account of such Bank a certified copy of an original official receipt received by the Company showing payment thereof. If the Company fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Company shall indemnify the Agent and the Banks for any incremental taxes, interest or penalties that may become payable by the Agent or any Bank as a result of any such failure. The agreements in this subsection 4.12 shall survive the termination of this Agreement and the payment of the Revolving Extensions of Credit and all other amounts payable hereunder. (b) Each Bank that is not incorporated under the laws of the United States of America or a state thereof agrees that it will deliver to the Company and the Agent (i) two duly completed copies of United States Internal Revenue Service Form 1001 or 4224 or successor applicable form, as the case may be, and (ii) an Internal Revenue Service Form W-8 or W-9 or successor applicable form. Each such Bank also agrees to deliver to the Company and the Agent two further copies of the said Form 1001 or 4224 and Form W-8 or W-9, or successor applicable forms or other manner of certification, as the case may be, on or before the date that any such form expires or becomes obsolete or after occurrence of any event requiring a change in the most recent form previously delivered by it to the Company, and such extensions or renewals thereof as may reasonably be requested by the Company or the Agent, unless in any such case an event (including, without limitation, any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Bank from duly completing and delivering any such form with respect to it and such Bank so advises the Company and the Agent. Such Bank shall certify (i) in the case of a Form 1001 or 4224, that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (ii) in the case of a Form W-8 or W-9, that it is entitled to an exemption from United States backup withholding tax. 4.13 Indemnity . The Company agrees to indemnify each Bank and to hold each Bank harmless from any loss or expense which such Bank may sustain or incur as a consequence of (a) default by the Company in payment when due of the principal amount of or interest on any Eurodollar Loans of such Bank, (b) default by the Company in making a borrowing or conversion after the Company has given a notice of borrowing in accordance with subsection 2.3 or a notice of conversion pursuant to subsection 4.4(a), or (c) default by the Company in making any prepayment after the Company has given a notice in accordance with subsection 4.1(a) or (d) a prepayment of a Eurodollar Loan on a day which is not the last day of an Interest Period with respect thereto, including, without limitation, in each case, any such loss or expense arising from the reemployment of funds obtained by it to maintain its Eurodollar Loans hereunder or from fees payable to terminate the deposits from which such funds were obtained. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by such Bank or the Agent to the Company shall be conclusive in the absence of manifest error. This covenant shall survive termination of this Agreement and payment of the outstanding Revolving Extensions of Credit and all other amounts payable hereunder. SECTION 5. REPRESENTATIONS AND WARRANTIES In order to induce the Agent and the Banks to enter into this Agreement and to make their respective Revolving Credit Loans and to issue and participate in Letters of Credit, the Company represents and warrants to the Agent and the Banks that: 5.1 Financial Condition.

Neither the Company nor any Subsidiary has on the Closing Date any material Debt, contingent liabilities, liabilities for taxes, unusual forward or long-term commitments or unrealized or anticipated losses from any unfavorable commitments, except as referred to or reflected or provided for in the Financial Statements or in Schedule 7.1. Since the date of the Financial Statements, neither the business nor the Property of the Company, any Subsidiary or, to the best of our knowledge, any Permitted Joint Venture have been materially and adversely affected as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property or cancellation of contracts, permits or concessions by any Governmental Authority, riot, activities of armed forces or acts of God or of any public enemy. (b) The unaudited consolidated financial statements of EPCO for the fiscal quarter ended March 31, 1999, copies of which have heretofore been delivered to each Bank, have been prepared in accordance with GAAP and present fairly the financial condition, results of operation and changes in financial position of EPCO and its Subsidiaries, as at the date or dates and for the period or periods stated. 5.2 No Change . Since March 31, 1999, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect. 5.3 Existence; Compliance with Law . The Company (a) is duly organized, validly existing and in good standing under the laws of the State of Delaware, (b) has the partnership power and authority, and the legal right, to own and operate its property, to lease the property it operates as lessee and to conduct the business in which it is currently engaged and which it proposes to be engaged after the Closing Date, (c) is duly qualified and in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification, except to the extent that the lack of such qualification could not have a Material Adverse Effect and (d) is in compliance with all Requirements of Law except to the extent that the failure to comply therewith could not, in the aggregate, have a Material Adverse Effect. 5.4 Power; Authorization; Enforceable Obligations . The Company has the partnership power and authority, and the legal right, to make, deliver and perform the Loan Documents and to borrow hereunder and has taken all necessary action to authorize the borrowings on the terms and conditions of this Agreement and to authorize the execution, delivery and performance of the Loan Documents. No consent or authorization of, filing with or other act by or in respect of any Governmental Authority is required in connection with the borrowings hereunder or with the execution, delivery, performance, validity or enforceability of the Loan Documents. This Agreement has been, and each other Loan Document will be, duly executed and delivered on behalf of the Company. This Agreement constitutes, and each other Loan Document when executed and delivered will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). 5.5 No Legal Bar . The execution, delivery and performance of the Loan Documents, the borrowings hereunder and the use of the proceeds thereof, will not violate any Requirement of Law or any Contractual Obligation of the Company, and will not result in, or require, the creation or imposition of any Lien on any of its or their respective properties or revenues pursuant to any Requirement of Law or Contractual Obligation. 5.6 No Default Neither the Company nor any Subsidiary is in default under or with respect to any Contractual Obligation in any respect which could have a Material Adverse Effect. No Default or Event of Default has occurred and is continuing. 5.7 Investments and Guaranties . At the date of this Agreement, neither the Company nor any Subsidiary has any Investments or has outstanding any Guarantee Obligations, except as permitted by this Agreement, reflected in the Financial Statements or disclosed to the Banks in Schedule 5.7. 5.8 Liabilities; Litigation . Except as otherwise expressly permitted under this Agreement, (i) neither the Company nor any Subsidiary has any material (individually or in the aggregate) liabilities, direct or contingent, other than liabilities incurred in the normal course of business, and (ii) there is no litigation, legal, administrative or arbitral proceeding, investigation or other action of any nature pending or, to the best knowledge of the Company, threatened against or affecting the Company or any Subsidiary which involves the reasonable possibility of any material judgment or liability greater than $10,000,000 and not fully covered (after satisfaction of any deductible) by insurance or which could reasonably be expected to have a Material Adverse Effect. No unusual or unduly burdensome restriction, restraint, or hazard exists by contract, Requirement of Law or otherwise relative to the business or Properties of the Company or any Subsidiary. 5.9 Taxes; Governmental Charges . The Company and its Subsidiaries have filed all tax returns and reports required to be filed and have paid all taxes, assessments, fees and other governmental charges levied upon any of them or upon any of their respective Properties or income which are due and payable, including interest and penalties (other than those the amount or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the Company); and no tax liens have been filed and, to the best knowledge of the Company, no claims are being asserted with respect to any such taxes, fees or other charges. 5.10 Titles, etc. Except as set forth on Schedule 5.10, the Company and its Subsidiaries have good title to their respective material (individually or in the aggregate) Properties, free and clear of all Liens except (i) Liens referred to in the financial statements described in subsection 5.1, (ii) Excepted Liens, and (iii) Liens otherwise permitted or contemplated by this Agreement. 5.11 Intellectual Property . The Company and each of its Subsidiaries owns or is licensed to use, all trademarks, trade names, copyrights, technology, know-how and processes necessary for the conduct of its business as currently conducted that are material to the condition (financial or other), business, or operations of the Company and its Subsidiaries (the "Intellectual Property"). No claim has been asserted and is pending by any Person with the respect to the use of any such Intellectual Property, or challenging or questioning the validity or effectiveness of any such Intellectual Property and the Company does not know of any valid basis for any such claim. The use of such Intellectual Property by the Company and each of its Subsidiaries does not infringe on the rights of any Person, subject to such claims and infringements as do not, in the aggregate, give rise to any liability on the part of the Company or any of its Subsidiaries that is material to the Company and its Subsidiaries taken as a whole. 5.12 Casualties; Taking of Properties . Neither the business nor the Properties of the Company or any Subsidiary have been materially and adversely affected as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property or cancellation of contracts, permits or concessions by any domestic or foreign government or any agency thereof, riot, activities of armed forces or acts of God or of any public enemy. 5.13 Use of Proceeds; Margin Stock; No Financing of Corporate Takeovers . The proceeds of the Working Capital Revolving Credit Loans will be used by the Company for working capital purposes in the ordinary course of business of the Company and for general partnership purposes, including to pay, in whole or in part, distributions on the limited partner interests of the Limited Partner in the Company (to enable the Limited Partner to make cash distributions with respect to the Units and the general partner interest of the Limited Partner) and the General Partner Interest (collectively the "Distributions") and for the purposes of making Investments. The proceeds of the Investment Revolving Credit Loans will be used by the Company to make Investments permitted pursuant to subsection 7.6 and other working capital and general partnership purposes, excluding however, for the purposes of making Distributions. No part of the proceeds of the Revolving Credit Loans hereunder will be used for "purchasing" or "carrying" any "margin stock" within the respective meanings of each of the quoted terms under Regulation U of the Board of Governors of the Federal Reserve System as now and from time to time hereafter in effect or for any purpose which violates the provisions of the Regulations of such Board of Governors. If requested by the Agent, the Company will furnish to the Agent a statement to the foregoing effect in conformity with the requirements of FR Form U-1 referred to in said Regulation U. No proceeds of any loan or extension of credit made pursuant to this Agreement will be used to acquire any security in any transaction which is subject to Sections 13 or 14 of the Securities Exchange Act of 1934, including particularly but without limitation Sections 13(d) and 14(d) thereof. Neither the Company nor any Subsidiary nor any Person acting on behalf of the Company or any Subsidiary has taken or will take any action which might cause any of the Loan Documents to violate Regulation U or any other regulation of the Board of Governors of the Federal Reserve System as the same may hereinafter be in effect. 5.14 Compliance with Law . Each of the Company and its Subsidiaries: (i) is not in violation of any Requirement of Law, which violation (in the event such violation were asserted by any Person through appropriate action) involves the reasonable possibility of having a Material Adverse Effect; and (ii) presently possesses all licenses, permits, franchises and other governmental authorizations necessary to the ownership of any of its Property, the operation of the Facilities and the conduct of its business, the failure to obtain which (in the event such failure were asserted by any Person through appropriate action) involves the reasonable possibility of having a Material Adverse Effect. 5.15 ERISA . The Company, its Subsidiaries and any Commonly Controlled Entity are in compliance in all material respects with the applicable provisions of ERISA with respect to each Plan which they maintain and have fulfilled their obligations under the minimum funding standards of ERISA with respect to each Single Employer Plan. No "prohibited transaction," as such term is defined in Section 4975 of the Internal Revenue Code of 1986, as amended, has occurred with respect to any such Plan which could subject the Company, its Subsidiaries or any Commonly Controlled Entity to any excise tax. No "reportable event," as such term is defined in Section 4043 of ERISA and the regulations issued thereunder (other than a reportable event not subject to the provision for 30-day notice to the PBGC under such regulations), has occurred with respect to any Plan. No Plan has been, or is likely to be, terminated in a manner which would result in the imposition of a Lien on the Property of the Company, any Subsidiary or any Commonly Controlled Entity pursuant to Section 4068 of ERISA. The present value of all benefits vested under each Single Employer Plan maintained by the Company, its Subsidiaries or any Commonly Controlled Entity (based on those assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits. Neither the Company nor any of its Subsidiaries nor any Commonly Controlled Entity is making or accruing (or has any obligation to make or accrue) an obligation to make any contribution to a Multiemployer Plan, nor has any such contribution been made within five years prior to the date hereof. Neither the Company nor any of its Subsidiaries nor any Commonly Controlled Entity provide for post-retirement benefits under Plans which are welfare benefit plans (as defined in Section 3(1) of ERISA). 5.16 Investment Company Act; Other Regulations . The Company is not an "investment company", or a company "controlled" by an "investment company", within the meaning of the Investment Company Act of 1940, as amended. The Company is not subject to regulation under any Federal or State statute or regulation which limits its ability to incur Indebtedness. 5.17 Accuracy and Completeness of Information .

In case any payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made. The Agent and the Banks agree promptly to notify the Company after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application.

Neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person's own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Banks for any recitals, statements, representations or warranties made by the Company or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Company to perform its obligations hereunder or thereunder. The Agent shall not be under any obligation to any Bank to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Company. 10.4 Reliance by Agent . The Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Company), independent accountants and other experts selected by the Agent. The Agent may deem and treat the payee of any Revolving Credit Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Agent. The Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Banks (or, if so specified by this Agreement, all Banks) as it deems appropriate or it shall first be indemnified to its satisfaction by the Banks against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Banks (or, if so specified by this Agreement, all Banks), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Banks and all future holders of the Revolving Credit Loans. 10.5 Notice of Default . The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Agent has received notice from a Bank or the Company referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". In the event that the Agent receives such a notice, the Agent shall give notice thereof to the Banks. The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Banks (or, if so specified by this Agreement, all Banks); provided that unless and until the Agent shall have received such directions, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Banks. 10.6 Non-Reliance on Agent and Other Banks . Each Bank expressly acknowledges that neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by the Agent hereinafter taken, including any review of the affairs of the Company or any affiliate thereof, shall be deemed to constitute any representation or warranty by the Agent to any Bank. Each Bank represents to the Agent that it has, independently and without reliance upon the Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Company and its affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Bank also represents that it will, independently and without reliance upon the Agent or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Company and its affiliates. Except for notices, reports and other documents expressly required to be furnished to the Banks by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Bank with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Company or any affiliate thereof that may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates. 10.7 Indemnification . The Banks agree to indemnify the Agent in its capacity as such (to the extent not reimbursed by the Company and without limiting the obligation of the Company to do so), ratably according to their respective Commitment Percentages in effect on the date on which indemnification is sought under this subsection 10.7 (or, if indemnification is sought after the date upon which the Revolving Credit Commitments shall have terminated and the Revolving Credit Loans shall have been paid in full, ratably in accordance with such Commitment Percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including, without limitation, at any time following the payment of the Revolving Credit Loans) be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of, the Revolving Credit Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Agent under or in connection with any of the foregoing; provided that no Bank shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the Agent's gross negligence or willful misconduct. The agreements in this subsection shall survive the payment of the Revolving Credit Loans and all other amounts payable hereunder. The Administrative Agent shall have the right to deduct any amount owed to it by any Bank under this subsection 10.7 from any payment made by it to such Bank hereunder. 10.8 Agent in Its Individual Capacity . The Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Company as though the Agent was not the Agent. With respect to its Revolving Credit Loans made or renewed by it and with respect to any Letter of Credit issued or participated in by it, the Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Bank and may exercise the same as though it were not the Agent, and the terms "Bank" and "Banks" shall include the Agent in its individual capacity. 10.9 Successor Agent . The Agent may resign as Agent upon 10 days' notice to the Banks and the Company. If the Agent shall resign as Agent under this Agreement and the other Loan Documents, then the Required Banks shall appoint from among the Banks a successor agent for the Banks, which successor agent shall (unless an Event of Default shall have occurred and be continuing) be subject to approval by the Company (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Agent, and the term "Agent" shall mean such successor agent effective upon such appointment and approval, and the former Agent's rights, powers and duties as Agent shall be terminated, without any other or further act or deed on the part of such former Agent or any of the parties to this Agreement or any holders of the Revolving Credit Loans. If no successor agent has accepted appointment as Agent by the date that is 10 days following a retiring Agent's notice of resignation, the retiring Agent's resignation shall nevertheless thereupon become effective and the Banks shall assume and perform all of the duties of the Agent hereunder until such time, if any, as the Required Banks appoint a successor agent as provided for above. After any retiring Agent's resignation as Agent, the provisions of this Section 10 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement and the other Loan Documents. SECTION 11. MISCELLANEOUS 11.1 Notices . Any notice, request or demand required or permitted to be given or made under or in connection with this Agreement or the Revolving Credit Loans shall be in writing and shall be mailed by first class or express mail, postage prepaid, or sent by telex, telegram, telecopy or other similar form of rapid transmission confirmed by mailing (by first class or express mail, postage prepaid) written confirmation at substantially the same time as such rapid transmission, or personally delivered to an officer of the receiving party. All such communications shall be mailed, sent or delivered, (a) if to the Company, to the address shown opposite its signature to this Agreement, or to such other address or to such individual's or department's attention as the Company may have furnished the Agent and the Banks in writing; or (b) if to the Agent, to its address shown opposite its signature to this Agreement, or to such other address or to such individual's or department's attention as it may have furnished to the Company and the Banks in writing; or (c) if to the Banks, to their respective addresses shown opposite their respective signatures to this Agreement, or to such other address or to such individual's or department's attention as any Bank may have furnished the Company and the Agent in writing. Any notice, request or demand so addressed and mailed shall be deemed to be given when so mailed, except that any notice, request or demand to or upon the Agent or the Banks pursuant to subsection 2.3, 2.4, 3.2, 4.1 or 4.4 or communications related to such notice, request or demand shall not be effective until actually received by the Agent; and any notice, request or demand so sent by rapid transmission shall be deemed to be given when receipt of such transmission is acknowledged, and any request or demand so delivered in person shall be deemed to be given when receipted for by, or actually received by, an authorized officer of the Company, the Agent or a Bank, as the case may be. 11.2 Amendments and Waivers . Any provision of this Agreement or any other Loan Document may be amended or waived if, but only if, such amendment or waiver is (a) consented to in writing by the Required Banks and (b) in writing and is signed by the Company (and/or any other Person which is a party to any other Loan Document being amended or with respect to which a waiver is being obtained) and the Agent; provided that no such amendment or waiver shall, (a) unless signed by all the Banks, (i) change the Revolving Credit Commitment of any Bank or subject any Bank to any additional obligation, (ii) change the principal of or decrease the rate of interest on the Revolving Credit Loans or any fees hereunder, (iii) postpone the date fixed for any payment of principal of or interest on the Revolving Credit Loans, the Indebtedness or any fees hereunder, (iv) change the Commitment Percentages or reduce the percentage specified in the definition of Required Banks, (v) defer or reduce any payment of principal or interest on the Revolving Credit Loans or (vi) amend, modify or waive any provision of this subsection, (b) amend, modify or waive any provision of Sections 3 or 10 without the written consent of the then Agent. Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Banks and shall be binding upon the Company, the Banks, the Agent and all future holders of the Revolving Credit Loans. In the case of any waiver, the Company, the Banks and the Agent shall be restored to their former position and rights hereunder and under the outstanding Revolving Credit Loans, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. 11.3 Invalidity . In the event that any one or more of the provisions contained in this Agreement or any other Loan Document shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement or any other Loan Document. 11.4 Successors and Assigns; Participations; Purchasing Banks . (a) This Agreement shall be binding upon and inure to the benefit of the Company, the Banks, the Agent, all future holders of the Revolving Credit Loans and their respective successors and assigns, except that the Company may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of each Bank. (b) Any Bank may, in the ordinary course of its commercial banking business and in accordance with applicable law, at any time sell to one or more banks or other entities ("Participants") participating interests in any Revolving Credit Loan owing to such Bank, any Revolving Credit Commitment of such Bank or any other interest of such Bank hereunder and under the other Loan Documents. In the event of any such sale by a Bank of participating interests to a Participant, such Bank's obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Bank shall remain solely responsible for the performance thereof, such Bank shall remain the holder of any such Revolving Credit Loan for all purposes under this Agreement and the other Loan Documents, and the Company and the Agent shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement and the other Loan Documents. The Company agrees that if amounts outstanding under this Agreement and the Revolving Credit Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of setoff in respect of its participating interest as if the amount of its participating interest were owing directly to it as a Bank under this Agreement or any Note, provided that such Participant shall only be entitled to such right of setoff if it shall have agreed in the agreement pursuant to which it shall have acquired its participating interest to share with the Banks the proceeds thereof as provided in subsection 8.3. The Company also agrees that each Participant shall be entitled to the benefits of subsections 4.11, 4.12 and 4.13 with respect to its participation in the Revolving Credit Commitments and the Revolving Credit Loans outstanding from time to time; provided, that no Participant shall be entitled to receive any greater amount pursuant to such subsections than the transferor Bank would have been entitled to receive in respect of the amount of the participation transferred by such transferor Bank to such Participant had no such transfer occurred. (c) Any Bank may, in the ordinary course of its business and in accordance with applicable law, at any time sell to any Bank or any affiliate thereof and, with the consent of the Company (so long as no Event of Default shall have occurred and is continuing, in which case the consent of the Company shall not be required) and the Agent (which in each case shall not be unreasonably withheld), to one or more additional banks or financial institutions ("Purchasing Banks") all or any part of its rights and obligations under this Agreement and the Revolving Extensions of Credit pursuant to a Commitment Transfer Supplement, substantially in the form of Exhibit D, executed by such Purchasing Bank, such transferor Bank (and, in the case of a Purchasing Bank that is not then a Bank or an affiliate thereof, by the Company and the Agent) and delivered to the Agent for its acceptance and recording in the Register. Upon such execution, delivery, acceptance and recording, from and after the Transfer Effective Date determined pursuant to such Commitment Transfer Supplement, (x) the Purchasing Bank thereunder shall be a party hereto and, to the extent provided in such Commitment Transfer Supplement, have the rights and obligations of a Bank hereunder with a Revolving Credit Commitment as set forth therein, and (y) the transferor Bank thereunder shall, to the extent provided in such Commitment Transfer Supplement, be released from its obligations under this Agreement (and, in the case of a Commitment Transfer Supplement covering all or the remaining portion of a transferor Bank's rights and obligations under this Agreement, such transferor Bank shall cease to be a party hereto). Such Commitment Transfer Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Bank and the resulting adjustment of Commitment Percentages arising from the purchase by such Purchasing Bank of all or a portion of the rights and obligations of such transferor Bank under this Agreement and the Revolving Credit Notes. On or prior to the Transfer Effective Date determined pursuant to such Commitment Transfer Supplement, the Company, at its own expense, shall, to the extent requested by the Purchasing Bank or the transferor Bank, execute and deliver to the Agent in exchange for the surrendered Revolving Credit Note a new Revolving Credit Note to the order of such Purchasing Bank in an amount equal to the Revolving Credit Commitment assumed by it pursuant to such Commitment Transfer Supplement and, if the transferor Bank has retained a Revolving Credit Commitment hereunder, new Revolving Credit Notes to the order of the transferor Bank in an amount equal to the Revolving Credit Commitment retained by it hereunder. Such new Revolving Credit Notes shall be dated the Closing Date and shall otherwise be in the form of the Revolving Credit Notes replaced thereby. The Revolving Credit Notes surrendered by the transferor Bank shall be returned by the Agent to the Company marked "canceled". (d) The Agent shall maintain at its address referred to in subsection 11.1 a copy of each Commitment Transfer Supplement delivered to it and a register (the "Register") for the recordation of the names and addresses of the Banks and the Revolving Credit Commitment of, and principal amount of the Revolving Credit Loans owing to, each Bank from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Company, the Agent and the Banks may treat each Person whose name is recorded in the Register as the owner of the Loan recorded therein for all purposes of this Agreement. The Register shall be available for inspection by the Company or any Bank at any reasonable time and from time to time upon reasonable prior notice. (e) Upon its receipt of a Commitment Transfer Supplement executed by a transferor Bank and Purchasing Bank (and, in the case of a Purchasing Bank that is not then a Bank or an affiliate thereof, by the Company and the Agent), together with payment to the Agent of a registration and processing fee of $4,000, the Agent shall (i) promptly accept such Commitment Transfer Supplement, (ii) on the Transfer Effective Date determined pursuant thereto record the information contained therein in the Register and (iii) give notice of such acceptance and recordation to the Banks and the Company. (f) The Company authorizes each Bank to disclose to any Participant or Purchasing Bank (each, a "Transferee") and any prospective Transferee any and all financial information in such Bank's possession concerning the Company and its affiliates which has been delivered to such Bank by or on behalf of the Company pursuant to this Agreement or which has been delivered to such Bank by or on behalf of the Company in connection with such Bank's credit evaluation of the Company and its affiliates prior to becoming a party to this Agreement. (g) If, pursuant to this subsection, any interest in this Agreement or any Revolving Credit Loan is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any state thereof, the transferor Bank shall cause such Transferee, concurrently with the effectiveness of such transfer, (i) to represent to the transferor Bank (for the benefit of the transferor Bank, the Agent and the Company) that under applicable law and treaties no taxes will be required to be withheld by the Agent, the Company or the transferor Bank with respect to any payments to be made to such Transferee in respect of the Revolving Credit Loans, (ii) to furnish to the transferor Bank (and, in the case of any Purchasing Bank registered in the Register, the Agent and the Company) either U.S. Internal Revenue Service Form 4224 or U.S. Internal Revenue Service Form 1001 (wherein such Transferee claims entitlement to complete exemption from U.S. federal withholding tax on all interest payments hereunder) and (iii) to agree (for the benefit of the transferor Bank, the Agent and the Company) to provide the transferor Bank (and, in the case of any Purchasing Bank registered in the Register, the Agent and the Company) a new Form 4224 or Form 1001 upon the expiration or obsolescence of any previously delivered form and comparable statements in accordance with applicable U.S. laws and regulations and amendments duly executed and completed by such Transferee, and to comply from time to time with all applicable U.S. laws and regulations with regard to such withholding tax exemption. (h) Nothing herein shall prohibit any Bank from pledging or assigning any Note to any Federal Reserve Bank in accordance with applicable law. 11.5 No Waiver; Cumulative Remedies . No failure to exercise and no delay in exercising, on the part of the Agent or any Bank, any right, remedy, power or privilege hereunder or under the Loan Documents, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided or provided in the Loan Documents are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law. 11.6 Payment of Expenses, Taxes and Indemnification . The Company agrees (a) to pay or reimburse the Agent for all its reasonable out-of-pocket costs and expenses incurred in connection with the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement, the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation of the transactions contemplated hereby and thereby, including, without limitation, the reasonable fees and disbursements of counsel to the Agent, (b) to pay or reimburse each Bank and the Agent for all its costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and any such other documents, including, without limitation, fees and disbursements of counsel to the Agent and to the several Banks and (c) to pay, indemnify, and hold each Bank and the Agent harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, which may be payable or determined to be payable in connection with the execution and delivery of, or consummation of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify, and hold each Bank and the Agent harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any such other documents or in respect of the use of the proceeds of the Revolving Credit Loans hereunder (all the foregoing, collectively, the "indemnified liabilities"), provided that the Company shall have no obligation hereunder with respect to indemnified liabilities arising from the gross negligence or willful misconduct of such indemnified party. The agreements in this subsection shall survive repayment of the Revolving Credit Loans and all other amounts payable hereunder. 11.7 GOVERNING LAW . THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 11.8 Several Obligations . The respective obligations of the Banks under this Agreement are several and not joint, and no Bank shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such). The failure of any Bank to perform any of its obligations hereunder shall not relieve any other Bank from any of its obligations hereunder. 11.9 Interest . (a) It is the intention of the parties hereto that each Bank shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Bank under laws applicable (including the laws of the United States of America, the State of New York or any other jurisdiction whose laws may be mandatorily applicable to such Bank notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in this Agreement or in any other Loan Document, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Bank that is contracted for, taken, reserved, charged or received by such Bank under this Agreement or under any other Loan Document shall under no circumstances exceed the maximum amount allowed by such applicable law (the "Maximum Rate"), and any excess shall be credited by such Bank on the principal amount of the Revolving Credit Loans (or, if the principal amount of the Revolving Credit Loans shall have been or would thereby be paid in full, refunded by such Bank to the Company); and (ii) in the event that the maturity of the Revolving Credit Loans is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Bank may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Bank as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Bank on the principal amount of the Revolving Credit Loans (or, if the principal amount of the Revolving Credit Loans shall have been paid in full, refunded by such Bank to the Company). (b) Recapture. If at any time the rate of interest on any Revolving Credit Loans would exceed the Maximum Rate but for the foregoing limitation, the interest rate on such Revolving Credit Loans shall remain at the Maximum Rate, notwithstanding subsequent reduction of the rate of interest on such Revolving Credit Loans, until the total amount of interest accrued thereon equals the amount of interest which would have accrued if the rate of interest on such Revolving Credit Loans had not been limited to the Maximum Rate, but nothing in this paragraph shall effect or extend the maturity of such Revolving Credit Loans. If at maturity or final payment of any Revolving Credit Loans, the total amount of interest accrued thereon is less than the total amount of interest which would have accrued had the rate of interest on such Revolving Credit Loans not been limited to the Maximum Rate, the Company agrees, to the full extent permitted by law, to pay to the Banks an amount equal to the positive difference, if any, derived by subtracting (a) the amount of interest which accrued thereon pursuant to the provisions of the foregoing two paragraphs from (b) the lesser of (i) the amount of interest which would have accrued on such Revolving Credit Loans if the Maximum Rate had at all times been in effect, and (ii) the amount of interest which would have accrued if the rate of interest on such Revolving Credit Loans, not limited to the Maximum Rate, had at all times been in effect. 11.10 Governmental Regulation . Anything contained in this Agreement to the contrary notwithstanding, no Bank shall be obligated to extend credit to the Company in an amount in violation of any limitation or prohibition. 11.11 Entire Agreement . This Agreement and the other Loan Documents embody the entire agreement and understanding between the Agent, the Banks and the Company and supersede all prior agreements and understandings between such parties relating to the subject matter hereof and thereof. 11.12 Exhibits . The exhibits attached to this Agreement are incorporated herein and shall be considered a part of this Agreement for the purposes stated herein, except that in the event of any conflict between any of the provisions of such exhibits and the provisions of this Agreement, the provisions of this Agreement shall prevail. 11.13 Titles of Sections and Subsections . All titles or headings to sections, subsections or other divisions of this Agreement or the exhibits hereto are only for the convenience of the parties and shall not be construed to have any effect or meaning with respect to the other content of such sections, subsections or other divisions, such other content being controlling as to the agreement between the parties hereto. 11.14 Number of Documents . All statements, notices, reports and requests hereunder shall be furnished to the Agent with sufficient counterparts so that the Agent may furnish one to each of the Banks. 11.15 SUBMISSION TO JURISDICTION; WAIVERS . (1) THE COMPANY HEREBY IRREVOCABLY AND UNCONDITIONALLY: (I) SUBMITS FOR ITSELF AND ITS PROPERTY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY, OR FOR RECOGNITION AND ENFORCEMENT OF ANY JUDGMENT IN RESPECT OF ANY THEREOF, TO THE NON-EXCLUSIVE GENERAL JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK, THE COURTS OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND APPELLATE COURTS FROM ANY THEREOF; (II) CONSENTS THAT ANY SUCH ACTION OR PROCEEDING MAY BE BROUGHT IN SUCH COURTS, AND WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT COURT AND AGREES NOT TO PLEAD OR CLAIM THE SAME; (III) AGREES THAT SERVICE OF PROCESS IN ANY SUCH ACTION OR PROCEEDING MAY BE EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL (OR ANY SUBSTANTIALLY SIMILAR FORM AND MAIL), POSTAGE PREPAID, TO IT AT ITS ADDRESS SPECIFIED IN SUBSECTION 11.1; (IV) AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO EFFECT SERVICE OF PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT TO SUE IN ANY OTHER JURISDICTION; AND (V) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LEGAL ACTION OR PROCEEDING REFERRED TO IN THIS SUBSECTION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES. (2) THE COMPANY, THE BANKS AND THE AGENT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN. 11.16 Interpretation . Any conflict or inconsistency between a provision of this Agreement and the corresponding provision of any of the Loan Documents shall be resolved in favor of this Agreement. 11.17 Counterparts . This Agreement may be executed in two or more counterparts, and it shall not be necessary that the signatures of all parties hereto be contained on any one counterpart hereof; each counterpart shall be deemed an original, but all of which together shall constitute one and the same instrument. 11.18 Co-Arrangers, etc. The Co-arrangers, co-agents and documentation agent, in their capacities as such, shall not have any duties or responsibilities under or pursuant to this Agreement. THIS WRITTEN AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE OTHER INSTRUMENTS AND DOCUMENTS EXECUTED IN CONNECTION HEREWITH, REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

EXHIBIT B-1 {Snell & Smith Opinion}

EXHIBIT B-2 ENTERPRISE PRODUCTS GP, LLC P.O. Box 4324 Houston, Texas 77210 September __, 1999 The Chase Manhattan Bank, as Agent, and the financial institutions parties to the Credit Agreement referred to below 270 Park Avenue New York, New York 10017 Ladies and Gentlemen: I am the Executive Vice President and Chief Legal Officer of Enterprise Products GP, LLC, a Delaware limited liability company and the sole general partner of Enterprise Products Operating L.P., a Delaware limited partnership (the "Borrower"), in connection with the Borrower's execution and delivery of the Credit Agreement, dated as of July 28, 1999 (the "Credit Agreement"), among the Borrower, The Chase Manhattan Bank, as agent for the Banks referred to below (in such capacity, the "Agent"), certain entities, as co-arrangers, administrative agent, documentation agent, syndication agent, managing agent, lead arranger and/or book manager, and the other financial institutions parties thereto (collectively, the "Banks"). This opinion is being furnished to you pursuant to Section 9.1(d)(ii) of the Credit Agreement. Unless otherwise defined herein, terms defined in the Credit Agreement are used herein as therein defined. In expressing the opinions expressed below, I have examined executed counterparts (or copies thereof) of each of the Loan Documents, the originals or conformed copies of such corporate or partnership records, agreements and instruments of the Borrower and the General Partner and the Limited Partner (individually, a "Partner" and, collectively, the "Partners"), certificates of public officials and of officers of the Borrower and the Partners and such other documents and records, and such matters of law, as I have deemed appropriate as a basis for the opinions hereinafter expressed. As to factual matters, I have relied upon, and assumed the accuracy of, (a) statements and certifications of representatives of the Borrower or officers or managers, as applicable, of the relevant Partner and of appropriate public officials, and (b) the representations and warranties of the Borrower and the Partners contained in or made pursuant to each of the Loan Documents to which they are respectively a party, and my opinion is limited to such factual matters in existence on the date hereof. In stating my opinion, I have assumed the genuineness of all signatures of persons signing the Loan Documents on behalf of parties thereto (including faxed copies of such signatures), other than the persons signing on behalf of the Borrower, the authenticity and completeness of all documents, certificates and records submitted to me as originals and the conformity to authentic original instruments of all documents (including any of the Loan Documents), certificates and records submitted to me as certified, conformed, faxed or photostatic copies. I have assumed further that the execution and delivery of the Loan Documents or any other instruments executed in connection with the Loan Documents, or as part of the same transaction as the Loan Documents, by any party other than the Borrower and the Partners have been duly

authorized by such other party and are legal, valid, binding and enforceable obligations of such other party. This opinion is limited in all respects to the laws of the State of Texas and federal law as in effect on the date hereof. I note that the Credit Agreement and certain of the other Loan Documents provide that they are to be governed by the laws of the State of New York. Accordingly, in expressing this opinion, I have assumed, with your permission, that the laws of the State of New York are identical in all respects to the laws of the State of Texas. Based upon the foregoing and subject to the limitations, qualifications, assumptions and exceptions set forth herein, I am of the opinion that: 1. The Borrower has the legal right to (i) own or lease the property which it owns or operates as lessee, (ii) conduct the business in which it is currently engaged and in which it proposes, as of the date hereof, to be engaged after the date hereof, (iii) make, deliver and perform the Credit Agreement and each of the other Loan Documents to which it is a party in accordance with the terms and provisions thereof and (iv) borrow under the Credit Agreement. The Borrower is in compliance with all Requirements of Law, except where the failure to so comply could not reasonably be expected to have a Material Adverse Effect. While I am not licensed to practice law in any jurisdiction other than the State of Texas, and therefore am unable to express an opinion as to whether the Borrower is required to qualify to do business as a foreign limited partnership in any jurisdiction, I do not believe that the Borrower would be required to so qualify in any jurisdiction other than the States of Texas, Alabama, Louisiana and Mississippi. No other filing, recording, publishing or other act is necessary or appropriate in connection with the existence or business of the Borrower. 2. The Borrower has taken all necessary legal action to authorize the borrowings by the Borrower on the terms and conditions of the Credit Agreement and the Loan Documents and to authorize the execution, delivery and performance of each of the Loan Documents to which it is a party in accordance with the terms and provisions thereof. 3. No approvals or consents of any Governmental Authority or other consents or approvals by any other Person which have not been obtained on or prior to the date hereof are required in connection with (a) the participation by the Borrower in the transactions contemplated by the Credit Agreement and the other Loan Documents, or the execution, delivery and performance by the Borrower of the Credit Agreement or any of the other Loan Documents and (b) the validity and enforceability thereof and the exercise by the Banks of their rights and remedies thereunder 4. The execution, delivery and performance by the Borrower of the Credit Agreement and each of the other Loan Documents in accordance with the terms thereof will not (a) violate any Requirement of Law or any Contractual Obligation of the Borrower, (b) result in the breach of, or constitute a default under, any indenture or loan or credit agreement or any other material agreement, lease or instrument of which I have knowledge to which the Borrower is a party or by which its properties may be bound, and (c) result in, or require, the creation or imposition of any Lien on any of its properties or revenues pursuant to any Requirement of Law or Contractual Obligation.

5. No litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the best of our knowledge, threatened by or against the Borrower or against any of its properties or revenues (a) with respect to the Credit Agreement or any of the other Loan Documents to which the Borrower is a party or any of the transactions contemplated thereby or (b) which, if adversely determined, could reasonably be expected to have Material Adverse Effect. This opinion is subject to, and qualified in all respects by, with your permission, the following: A. I have not been called upon to, and accordingly do not, express any opinion as to the various state and federal laws regulating banks or the conduct of their business that may relate to the Loan Documents and the transactions provided for therein. B. All statements in this opinion which are stated "to my knowledge" are based, to the extent I have deemed proper, solely upon reasonable inquiries of an officer or representative of the Partners. Although I have not independently verified the accuracy of the statements, I have discussed the statements with the individuals making them, and I have no reason to believe that any such statement is untrue or inaccurate in any material respect. This opinion is limited to matters stated herein and no opinion is implied or may be inferred beyond the matters expressly stated. I disclaim any obligation to up-date this opinion or to advise you of any changes in any of the opinions or other matters set forth herein. This opinion is being furnished only to, and is solely for the benefit of, the addressees who are parties to the Credit Agreement on the date hereof (each of whom may rely upon this opinion as of the date hereof). This opinion may not be used, circulated, quoted, relied upon or otherwise referred to by any other person or entity or for any other purpose without my prior written consent. Very truly yours, Richard H. Bachmann Executive Vice President and Chief Legal Officer operatingopinion.wpd 3
