Item 1.01. Entry into a Material Definitive Agreement.

On August 14, 2008, TEPPCO O/S Port System, LLC (“TEPPCO LLC”), an indirect wholly-owned subsidiary of TEPPCO Partners, L.P. (“TEPPCO”) entered into a Partnership Agreement (the “Partnership Agreement”) for the Texas Offshore Port System, a Delaware general partnership (“TOPS”) with Enterprise Offshore Port System, LLC (“Enterprise LLC”), an indirect wholly-owned subsidiary of Enterprise Products Partners L.P. (“Enterprise”) and Oiltanking Freeport L.P. (“Oiltanking LP”), a subsidiary of Oiltanking Holding Americas, Inc. (“Oiltanking”). TOPS has been formed to design, construct, own and operate a new Texas offshore crude oil port and pipeline system to facilitate delivery of waterborne crude oil to refining centers along the upper Texas Gulf Coast. Through their respective subsidiaries, Enterprise, TEPPCO and Oiltanking will each own a one-third interest in TOPS, and expect to invest a total of $1.8 billion in the project, which is scheduled to begin service in the fourth quarter of 2010. The offshore terminal will require approval by the U.S. Coast Guard, while the onshore pipeline and storage facilities will be subject to review by the U.S. Environmental Protection Agency, Army Corps of Engineers and Department of Transportation.

The Partnership Agreement provides that:

TOPS will be governed by a management committee comprised of representatives appointed by each of TEPPCO LLC, Enterprise LLC and Oiltanking LP (each referred to herein as a “Partner”). Each Partner’s representatives, whether one or more, are entitled to vote such Partner’s interest in TOPS. The management committee may designate officers to act on TOPS’s behalf.

The Partners are obligated to fund capital contributions necessary to form TOPS and design, construct, install and place in service the offshore crude oil port and pipeline system. An affiliate of each Partner has guaranteed up to $700 million of such Partner’s capital contribution obligations. The Partnership Agreement also provides for the dilution of a Partner’s interest in TOPS upon such Partner's failure to contribute its share of capital required to construct the offshore crude oil port and pipeline facilities.

§	A subsidiary of Enterprise will act as operator and construction manager for TOPS.

Except with respect to transfers to affiliates or transfers resulting from a foreclosure, any Partner undergoing a change of control or desiring to transfer all or any portion of its interest in TOPS must first offer to transfer such interest to the non-transferring Partners as a group based upon the same terms and conditions as those under which, and for the same value that, the transferring Partner would receive under the proposed transfer. The non-transferring Partners will have 60 days after receiving notice of the transfer within which to elect to acquire all of such interest proposed to be transferred.

Generally, TOPS will distribute available cash (as defined in the Partnership Agreement) from operations to the Partners in proportion to their respective partnership interests on a monthly basis; provided, however, that the Partnership Agreement allows for special allocations of cash flow to Partners that choose to participate in the funding of future expansions of the facilities.

This transaction was reviewed and approved by the Audit, Conflicts and Governance Committee of the board of directors of TEPPCO’s general partner. Dan L. Duncan and certain of his affiliates, including Enterprise GP Holdings L.P., a publicly-traded partnership that owns the general partners of TEPPCO and Enterprise, control TEPPCO and Enterprise.

This report contains only a summary of certain provisions of the Partnership Agreement. The summary does not purport to be complete and is qualified by reference to the Partnership Agreement,

which is filed as an exhibit hereto. The Partnership Agreement contains representations, warranties and other provisions that were made, among other things, to provide the parties thereto with specified rights and obligations and to allocate risk among them, and such agreement should not be relied upon as constituting a description of the state of affairs of any of the parties thereto or any other person.

Such offer will be made by a good faith written offer (the “Offer Notice”) to transfer all of the Subject Interest and must contain a complete description of the transaction, including any other transactions on which such transaction is contingent (the “Proposed Transaction”), in which the Transferring Party proposes to Transfer the Subject Interest, including the name of the ready, willing and able Transferee (including, if applicable, the name of the Person ultimately Controlling such Transferee, if known), the known or anticipated closing date of the Proposed Transaction, the consideration, if any, specified for the Subject Interest (if there is no consideration, the Offer Notice will state as such), and any other material terms and conditions of the Proposed Transaction (including, to the extent the Transferring Party is not prohibited from making such disclosure, the terms of any other transactions contingent on such transaction (or on which such transaction is contingent), provided, that the Transferring Party will not, and will not permit its Affiliates who are not Partners to, agree to keep confidential the terms of any such contingent transaction primarily to circumvent the requirement in this clause). Each Non-Transferring Partner will have 60 Days (as extended pursuant to Sections 3.4(e)(iv), (v) and (vi), the “Option Period”) after its receipt of the Offer Notice within which to elect to acquire all of such Subject Interest upon the terms and conditions contained in the Offer Notice or determined in accordance with 3.4(e)(iv), (v) and (vi). If, within the Option Period, one or more Non-Transferring Partners elect to acquire such Subject Interest, then (1) such Non-Transferring Partner(s) will each deliver its own separate written notice to the Transferring Party and to the other Non-Transferring Partner(s) during such period that expresses such desire to purchase the Subject Interest (each, an “Acceptance Notice”) and (2) such Non-Transferring Partner(s) and the Transferring Party will use good faith commercially reasonable efforts to close such transaction in accordance with Section 3.4(a)(i) no later than the later to occur of (x) the known or anticipated closing date set forth in the Notice Offer or (y) 60 Days after the last Day of the Option Period.

The right herein created in favor of the Non-Transferring Partners as a group is an option to acquire all, or none, of the Subject Interest offered for sale by the Transferring Party. If all the Non-Transferring Partners elect to purchase the Subject Interest, unless otherwise agreed, each such Non-Transferring Partner will purchase a pro-rata portion of the Subject Interest based on its respective Partnership Interest. If the Non-Transferring Partners as a group decline to acquire all of the Subject Interest of the Transferring Party in accordance with this Section 3.4(e) or if the Option Period has expired without delivery by any Non-Transferring Partner of an Acceptance Notice, the Transferring Party may Transfer such Subject Interest to the Transferee named in the Offer Notice delivered to the Non-Transferring Partners upon the terms described in such Offer Notice. If such Transfer does not occur substantially in accordance with the terms of such Offer Notice, such Transfer will have been in violation of this Section 3.4(e) and be null and void ab initio and the Transferring Party and the Subject Interest will again be subject to the provisions of this Section 3.4(e).

(iii) Upon consummation of any Transfer made in accordance with this Section 3.4(e) (whether to a Partner or any other Person), such Transferee and its Partnership Interest will automatically become a party to and be bound by this Agreement and will thereafter have all of the rights of a Party and the obligations of a Partner hereunder; provided, however, that notwithstanding the foregoing, all Transfers pursuant to this Section 3.4(e) must also comply with and be governed by the other provisions of this Agreement, including any restrictions on Transfers therein and on any Transferee becoming a Substituted Partner, for such Transferee to have all of the rights of a Partner hereunder.

(iv) If no consideration is to be paid in the Proposed Transaction for the Subject Interest, the Transferring Party will state as such in its Offer Notice and will state its good faith determination of the Fair Market Value of the Subject Interest, which will be the consideration for which the Subject Interest is offered to the Non-Transferring Partners. If a Majority Interest disagrees with such determination, they will notify the Transferring Party of such disagreement within 20 Business Days of receiving the Offer Notice. If such disagreement is not resolved within 20 Business Days after such notice to the Transferring Party, any Partner may cause such disagreement to be resolved by delivering notice (a “Value Disagreement Notice”) to the Transferring Party and the other Partners. If more than one Partner delivers a Value Disagreement Notice, all such Notices shall be aggregated into one. The Value Disagreement Notice must include the names of

three Appraisers (each of which must be independent from the Company, the Partners and their respective Affiliates) proposed by the delivering Partner. If more than one Partner delivers a Value Disagreement Notice, such Partners must together identify three Appraisers. The Transferring Party must, within ten Days after receipt of the Value Disagreement Notice, choose one of the Appraisers listed on the Value Disagreement Notice to determine the Fair Market Value of the Subject Interest that is in dispute (the “Appraised Value”). Subject to the provisions of Section 3.4(e)(vii), the Partners delivering the Value Disagreement Notice(s) and the Transferring Party will share on an equal basis the costs of the designated Appraiser. The Transferring Partner and each applicable Non-Transferring Partner will promptly provide such Appraiser with all information each deems necessary or appropriate to determine such Appraised Value, and such Appraiser shall determine such Appraised Value within 30 Days after receipt of all such information. If a Value Disagreement Notice is delivered, the Option Period will be extended until the date five Business Days after the disagreement described in such Value Disagreement Notice is resolved. The consideration to be paid by the applicable Non-Transferring Partners for the Subject Interest then will be a cash amount equal to the Appraised Value of the Subject Interest, as determined by the Appraiser.

(v) If the Proposed Transaction (including, to the extent the Transferring Party is not prohibited from making such disclosure, the terms of any other transactions contingent on such transaction (or on which such transaction is contingent), provided, that the Transferring Party will not, and will not permit its Affiliates to, agree to keep confidential the terms of any such contingent transaction primarily to circumvent the requirement in this clause) contemplates the transfer of any asset, property, interest or right in addition to the Subject Interest to the proposed Transferee or its Affiliate, then the Transferring Party must include in its Offer Notice its good faith determination of the Fair Market Value of the Subject Interest, which will be the consideration for which the Subject Interest is offered to the Non-Transferring Partners. If a Majority Interest disagrees with such determination, they will notify the Transferring Party of such disagreement within 20 Business Days of receiving the Offer Notice. If such disagreement is not resolved within 20 Business Days after such notice to the Transferring Party, any Partner may cause such disagreement to be resolved by delivering a Value Disagreement Notice to the Transferring Party and the other Partners. If more than one Partner delivers a Value Disagreement Notice, all such Notices shall be aggregated into one. The Value Disagreement Notice must include the names of three Appraisers (each of which must be independent from the Company, the Partners and their respective Affiliates) proposed by the delivering Partner. If more than one Partner delivers a Value Disagreement Notice, such Partners must together identify three Appraisers. The Transferring Party must, within ten Days after receipt of the Value Disagreement Notice, choose one of the Appraisers listed on the Value Disagreement Notice to determine the Appraised Value. Subject to the provisions of Section 3.4(e)(vii), the Partners delivering the Value Disagreement Notice(s) and the Transferring Party will share on an equal basis the costs of the designated Appraiser. The Transferring Party and each applicable

Non-Transferring Partner will promptly provide such Appraiser with all information necessary or appropriate to determine the Appraised Value, and such Appraiser shall determine the Appraised Value within 30 Days after receipt of all such information. If a Value Disagreement Notice is delivered, the Option Period will be extended until the date five Business Days after the disagreement described in such Value Disagreement Notice is resolved. The consideration to be paid by the applicable Non-Transferring Partners for the Subject Interest then will be a cash amount equal to the Appraised Value of the Subject Interest, as determined by the Appraiser.

(vi) If any portion of the consideration set forth in the Offer Notice is to be paid in a form other than cash or cash equivalents (including real or personal property, promissory notes, securities, contractual benefits, assumption of liabilities or anything else of value) (“Non-Cash Consideration”), the Transferring Party will state in its Offer Notice its good faith determination of the Fair Market Value of the Subject Interest, which will be the consideration for which the Subject Interest is offered to the Non-Transferring Partners. If a Majority Interest disagrees with such determination, they will notify the Transferring Party of such disagreement within 20 Business Days of receiving the Offer Notice. If such disagreement is not resolved within 20 Business Days after such notice to the Transferring Party, any Partner may cause such disagreement to be resolved by delivering a Value Disagreement Notice to the Transferring Party and the other Partners. If more than one Partner delivers a Value Disagreement Notice, all such Notices must be aggregated into one. The Value Disagreement Notice must include the names of three Appraisers (each of which must be independent from the Company, the Partners and their respective Affiliates) proposed by the delivering Partner. If more than one Partner delivers a Value Disagreement Notice, such Partners must together identify three Appraisers. The Transferring Party must, within ten Days after receipt of the Value Disagreement Notice, choose one of the Appraisers listed on the Value Disagreement Notice to determine the Appraised Value. Subject to the provisions of Section 3.4(e)(vii), the Partners delivering the Value Disagreement Notice(s) and the Transferring Party will share on an equal basis the costs of the designated Appraiser. The Transferring Party and each applicable Non-Transferring Partner will promptly provide such Appraiser with all information that each deems necessary or appropriate to determine the Appraised Value, and such Appraiser shall determine the Appraised Value within 30 Days after receipt of all such information. If a Value Disagreement Notice is delivered, the Option Period will be extended until the date five Business Days after the disagreement described in such Value Disagreement Notice is resolved. The consideration to be paid by the applicable Non-Transferring Partners for the Subject Interest then will be a cash amount equal to the Appraised Value of the Subject Interest, as determined by the Appraisers.

(vii) Any Transferring Party may withdraw its offer altogether (including to the original offeror) if the Appraised Value is less than 90% of the Fair Market Value stated in the Offer Notice, provided that in such case the Transferring Party will be solely responsible for the costs of the designated

Appraiser. Absent fraud or manifest error, the Appraised Value determination will be final and binding and not subject to further appeal.

(f) Right of Purchase Upon Change of Control.

(i) Right of Purchase.

(A) Subject to Sections 3.4(f)(i)(D), if a Change of Control occurs with respect to any Party (the “Affected Partner”), then all other Partners as a group (the “Non-Affected Partners”) will have the right to purchase all of such Party’s interest in the Company (the “Affected Interest”) for the Fair Market Value of such interest either as stated in the Change of Control Notice or as determined, if applicable, in accordance with Section 3.4(f)(i)(C).

(B) If a Change of Control occurs with respect to any Party, such Affected Partner must, as soon as reasonably possible after the Change of Control, deliver to each Non-Affected Partner a written notice (the “Change of Control Notice”) containing the following information: (1) the name of the Person ultimately Controlling such Party following the Change of Control as a result of the transaction and the relationship between such Person and the Affected Partner; (2) a description of the transaction constituting a Change of Control of such Partner, including such Partner’s good faith determination of (x) the total value of the transaction as a whole (to the extent that disclosure thereof is not prohibited by Law or by a confidentiality agreement, a waiver of which cannot reasonably be obtained) and (y) the Fair Market Value of the Affected Interest on the closing date of such transaction; and (3) the closing date of such transaction.

(C) If a Majority Interest disagrees with the Affected Partner’s determination of any value calculated in the Change of Control Notice, they will notify the Affected Partner of such disagreement within ten Business Days of the Change of Control Notice Date. If such disagreement is not resolved within ten Business Days after such notice to the Affected Partner, any Partner may cause such disagreement to be resolved by delivering a Value Disagreement Notice to the Affected Party and the other Partners. The Value Disagreement Notice must include the names of three Appraisers (each of which must be independent from the delivering Partner and its Affiliates) proposed by the delivering Partner. The Affected Party must, within ten days after receipt of the Value Disagreement Notice, choose one of the Appraisers listed on the Value Disagreement Notice to determine the Appraised Value. The Non-Affected Partners and the Affected Partner will share on an equal basis the costs of the designated appraiser. The Affected Partner and each Non-Affected Partner will promptly provide such Appraiser with all information that each deems necessary or appropriate to determine such

Appraised Value, and such Appraiser shall determine the Appraised Value within 30 Days after receipt of all such information. If a Value Disagreement Notice is delivered, the Change of Control Option Period will be extended until the date five Business Days after the disagreement described on such Value Disagreement Notice is resolved. The consideration to be paid by the applicable Non-Affected Partners for the Affected Interest then will be a cash amount equal to the Appraised Value of the Affected Interest, as determined by the resolution of the Appraiser.

(D) The Non-Affected Partners will have 60 days (as extended pursuant to Section 3.4(f)(i)(C), the “Change of Control Option Period”) after the Change of Control Notice Date within which to elect to acquire all of the Affected Interest pursuant to this Section 3.4(f)(i). If one or more Non-Affected Partners elects to acquire the Affected Interest by delivering notice within the Change of Control Option Period, then such Non-Affected Partner or Partners and the Affected Partner will use good faith, commercially reasonable efforts to close such Transfer no later than 60 days after the expiration of the Change of Control Option Period. Subject to Section 3.4(g), if the Non-Affected Partner(s) and the Affected Partner use good faith, commercially reasonable efforts to promptly close such Transfer, but do not close such Transfer within 90 days after the expiration of the Change of Control Option Period, the Non-Affected Partners’ rights to acquire the Affected Interest will terminate as of such 90th day.

(ii) If a Non-Affected Partner does not elect to acquire its proportionate share of the Affected Interest, each of the remaining Non-Affected Partners will, subject to the terms and conditions contained in Section 3.4(f)(i), have the right to acquire a proportionate portion of the remaining Affected Interest based on the relation of its Partnership Interest to the Partnership Interests of all Non-Affected Partners desiring to acquire a portion of such share of the Affected Interest. The right herein created in favor of the Non-Affected Partners as a group is an option to acquire all, or none, of the Affected Interest. If the Non-Affected Partners as a group decline to acquire all of the Affected Interest in accordance with this Section 3.4(f) or if the offer to sell contained in Section 3.4(f)(i) has expired, the right to acquire provided by this Section 3.4(f) will terminate.

(g) Governmental Consents. If any governmental consent or approval is required with respect to any Transfer, the Transferee will have a reasonable amount of time (not to exceed one year from the date upon which such Transfer would have been otherwise consummated in accordance with the terms of this Agreement) to obtain such consent or approval. All Partners will use reasonable, good faith efforts to cooperate with the Transferee attempting to obtain, and to assist in timely obtaining, such consent or approval; provided that no Partner will be required to incur any out-of-pocket costs in connection with such cooperation and assistance. After the expiration of such waiting period, such Transferee will forfeit its rights to acquire the Partnership Interest subject to such proposed Transfer with respect to such specific transaction; provided, however, that

such forfeiture will not limit or otherwise affect the forfeiting Transferee’s rights with respect to any subsequent proposed Transfer.

(h) Documentation; Validity of Transfer. The Company may not recognize for any purpose any purported Transfer of all or any part of a Partnership Interest unless and until the applicable provisions of Section 3.4 have been satisfied and the Company has received, on behalf of the Company (with copies to each of the Non-Transferring Partners), a document substantially in the form attached hereto as Exhibit B executed by both the Transferor (or if the Transfer is on account of the death, incapacity, or liquidation of the Partner, its legal or authorized representative) and the Transferee. Each Transfer and, if applicable, admission of a Substituted Partner complying with the provisions of Section 3.4 is effective against the Company as of the first Business Day of the calendar month immediately succeeding the month in which (i) the Company receives the documents required by this Section 3.4(h) reflecting such Transfer and (ii) all other requirements of Section 3.4 have been met.

(i) Closing of a Transfer. At the closing of the Transfer of a Partnership Interest pursuant to this Agreement, (i) the Transferee will deliver to the Transferor the full consideration agreed upon (except as otherwise identified in the Offer Notice or as agreed to between the Transferor and the Transferee) and (ii) the Transferor will Transfer its Partnership Interest to the Transferee free and clear of any and all liens, claims, security interests and other encumbrances, other than those created by this Agreement or any loan documents evidencing indebtedness of the Company for borrowed money. Any Partnership Interest transfer or similar taxes involved in such sale will be the sole responsibility of the Transferor, and the Transferor will provide the Transferee with such evidence of the Transferor’s authority to Transfer hereunder and such tax lien waivers and similar instruments as the Transferee may reasonably request.

(j) Pledge; Foreclosure Transfers. The Parties expressly acknowledge and agree that each Party will grant a Security Interest in its Partnership Interests pursuant to Section 16.18. Foreclosure Transfers with respect to either such Security Interest are permitted hereunder without the consent of the Partners, and any such proper Foreclosure Transfer shall entitle a Partner that forecloses on the underlying Security Interest to become a Substituted Partner.

(k) Security Interest Transfers. Notwithstanding anything to the contrary contained herein, any Party has the right to grant a Security Interest, in connection with any bona fide financing transaction, in any right or obligation such Party may have arising out of or related to this Agreement, the Company, or such Party’s Partnership Interest, or any interest herein or therein, and make a Transfer in connection with any such Security Interest; provided, however, that (i) no such Security Interest may be created in violation of Sections 3.4(a)(i) or 3.4(b)(i), (ii) the Company must be notified of any such Security Interest promptly after the creation thereof, and (iii) except as set forth to the contrary in Section 3.4(j), any Foreclosure Transfer with respect to a Security Interest in a Partnership Interest shall entitle a non-Partner that forecloses on the underlying Security Interest only to become a Transferee and not a Substituted Partner. If such foreclosing Person is already a Partner, such Partner’s status as a Partner will

remain unchanged but its Partnership Interest will be increased by the Partnership Interest acquired through the Foreclosure Transfer.

3.5 Possible Additional Restrictions on Transfer. Notwithstanding anything to the contrary contained in this Agreement, in the event of (a) the enactment (or imminent enactment) of any legislation, (b) the publication of any temporary or final regulation by the Treasury Department (“Treasury Regulation”), (c) any ruling by the Service, or (d) any judicial decision that in any such case, in the opinion of tax counsel to the Company, would result in the taxation of the Company for federal income tax purposes as a corporation or would otherwise subject the Company to being taxed as an entity for federal income tax purposes, this Agreement will be deemed to impose such restrictions on the Transfer of a Partnership Interest as may be required, in the opinion of counsel to the Company, to prevent the Company from being taxed as a corporation or otherwise being taxed as an entity for federal income tax purposes, and the Partners hereby agree thereafter to amend this Agreement as necessary or appropriate to impose such restrictions.

3.6 Additional Partnership Interests. Additional Partnership Interests may be created and issued to non-Partners and to existing Partners; provided that, any non-Partner receiving a Partnership Interest in such issuance shall be admitted to the Company as a Partner, only upon the vote of a Unanimous Non-Defaulting Interest and subject to the terms and conditions of this Agreement. Such admission must comply with any additional terms and conditions that a Unanimous Non-Defaulting Interest may in their sole discretion determine at the time of admission. A document, in a form acceptable to a Unanimous Non-Defaulting Interest, will specify the terms of admission or issuance and will include, among other things, the Partnership Interest applicable thereto. Any such admission of a new Partner also must comply with the provisions of Section 3.4(a)(iii). The provisions of this Section 3.6 will not apply to Transfers of Partnership Interests.

3.7 Information.

(a) Except as specifically set forth to the contrary in Section 3.7(b), no Person other than a Partner is entitled to any information with respect to the Company unless otherwise approved by a Majority Interest.

(b) The Parties acknowledge that, from time to time, they may receive information from or regarding the Company, its Subsidiaries, its customers or any other Partner or their Affiliates in the nature of trade secrets or secret or proprietary information or information that is otherwise confidential, the release of which may be damaging to the Company, its Subsidiaries, the Partner or their Affiliates, as applicable, or Persons with which they do business (“Confidential Information”). Each Party will, and will cause its Affiliates who are not Partners to, (A) hold in strict confidence any such Confidential Information it receives and (B) not disclose such Confidential Information to any Person other than another Partner, except for disclosures: (i) to comply with applicable Laws or, rules or regulations of any applicable securities exchange or market; (ii) under compulsion of judicial process, including to Arbitrators in any Proceeding involving the Partners; (iii) in connection with any proposed Transfer of all or part of a Partnership Interest in the Company of such Party or the proposed sale of

all or substantially all of such Party or its direct or indirect parent, to Affiliates, advisers or representatives of the Partner or Persons to which such interest may be Transferred as permitted by this Agreement, but only if the recipients of such Confidential Information have agreed in writing to be bound by confidentiality provisions that are no less stringent than those set forth in this Section 3.7(b); (iv) of Confidential Information that such Party also has received from a source independent of the Company or its Subsidiaries and that such Party reasonably believes such source obtained such information without breach of any obligation of confidentiality; (v) of Confidential Information obtained prior to the formation of the Company, provided that this sub-clause (v) will not relieve any Partner or any of its Affiliates from any obligations it may have to any other Partner or any of its Affiliates under any existing confidentiality agreement; (vi) to members, partners, officers, employees, Affiliates, lenders, accountants and other representatives of such Partner with a need to know such Confidential Information, provided that such Partner will be responsible for such representatives’ use and disclosure of any such Confidential Information; or (vii) of public information. The confidentiality obligations set forth in this Section 3.7(b) will terminate with respect to any Confidential Information five years after disclosure of such information to the Company or the Partners (or possibly longer if covered by separate confidentiality obligations). No Partner may (directly or indirectly) permit the use of Confidential Information in a manner adverse to the interests of the Company or the Partner disclosing such Information, except as permitted by this Section 3.7(b). No rights in Confidential Information are transferred or will be deemed to be transferred upon any disclosure hereunder. The Parties acknowledge that a breach of the provisions of this Section 3.7(b) may cause irreparable injury to the Company or its Subsidiaries or another Partner for which monetary damages are inadequate, difficult to compute, or both. Accordingly, the Parties agree that the provisions of this Section 3.7(b) may be enforced by injunctive action or specific performance.

(c) The Parties acknowledge that, from time to time, the Company and its Subsidiaries may need information from any or all of such Parties for various reasons, including compliance with Laws. Each Party will provide to the Company and its Subsidiaries all information reasonably requested by the Company and its Subsidiaries within a reasonable amount of time from the date such Party receives such request; provided, however, that no Party will be obligated to provide such information to the Company and its Subsidiaries to the extent such disclosure (i) could reasonably be expected to result in the breach or violation of any contractual obligation (if a waiver of such restriction cannot reasonably be obtained) or applicable Law or (ii) involves secret, confidential or proprietary information.

3.8 Liability to Third Parties. Except as required by the Act or as otherwise expressly agreed to in writing, no Partner will be liable to any Person (including any third party or to any other Partner) (a) as the result of any act or omission of another Partner or (b) for losses, liabilities or obligations of the Company or any of its Subsidiaries. The Company will use its best efforts to cause all contracts, leases, subleases, notes, deeds of trust and other agreements to which it is a party to contain an appropriate provision limiting the claims of all parties thereto to the assets of the Company and expressly waiving any rights of such parties to proceed against the Partners, jointly or severally.

3.9 Dissociation. Notwithstanding the fact that a Party may dissociate (which must be accomplished by delivery of written notice to the Company) by express will at any time pursuant to Sections 15-103(b)(4) and 15-602(a) of the Act, any dissociation by any Party without the express prior written consent of all other Parties will be wrongful and a breach of this Agreement (as set forth in Section 15-602(b) of the Act). If any Party wrongfully dissociates or attempts to dissociate:

(a) such Party will be liable to the Company for its allocable share of all Initial Facilities Capital Contributions required prior to and following such dissociation, resignation or withdrawal, regardless of whether the relevant Capital Call Notice has been delivered prior to or after such dissociation, resignation or withdrawal;

(b) such Party will be liable to the Company and the other Partners for all Losses caused by such dissociation, resignation or withdrawal, including any incidental, indirect, special, exemplary, punitive, or consequential damages of any kind or nature;

(c) such Party will be a non-Partner Party, except that (i) such Party will not be entitled to receive distributions of any kind or character from the Company, (ii) such Party will not be allocated any income or loss by the Company and (iii) such Party’s former Partnership Interest will be considered cancelled for all purposes until the end of the term of the Company; and

(d) such Party waives its right to statutory buyout of its Partnership Interest (to which it might otherwise have been entitled under Section 15-701 of the Act), provided that if (and only if) such Party is held in a final, nonappealable judgment to be entitled to buyout of its Partnership Interest, such buyout will be for 2/3 of the Fair Market Value (determined in the Company’s reasonable judgment, taking into account all factors reasonably deemed relevant by the Company) of such Partnership Interest (with such 1/3 discount, as is agreed by the Parties hereto, reflecting the damage done to the Company by such wrongful dissociation) and will be payable solely by an unsecured promissory note issued by the Company (i) with a term of 10 years, non-compounding interest payable annually at a rate of interest reasonably determined by the Company and the entire principal amount thereof payable upon maturity, (ii) with no covenants of the Company other than the obligation to pay interest annually and principal upon maturity and (iii) with a provision stating that such promissory note is solely an obligation of the Company and expressly non-recourse to the Partners.

Notwithstanding anything to the contrary herein, the dissociation (wrongful or otherwise) of any Party will not cause the dissolution or winding up of the Company. For the avoidance of doubt, a Transfer of a Partnership Interest in accordance with Section 3.4 will be deemed not to constitute a dissociation, resignation or withdrawal by a Party.

3.10 Lack of Partner Authority. No Partner has the authority to act on behalf of any other Partner. No Partner has the authority or power to act as agent for or on behalf of the Company, do any act that would be binding on the Company or any of its Subsidiaries, or incur any expenditure on behalf of the Company or any of its Subsidiaries, unless expressly authorized to do so in writing by the Company.

3.11 Not a Security. The Partnership Interests are deemed not to be a “security” under the Uniform Commercial Code of Texas, Delaware or any other relevant jurisdiction.

3.12 Party in Default. Except to the extent required by applicable Laws, a Party in Default does not have any voting rights or rights to distributions of a Partner in the Company or under this Agreement (and shall not be an Eligible Partner) during the existence and continuation of such Default, but a Party in Default remains primarily obligated for, and subject to, its obligations under this Agreement.

ARTICLE IV

CAPITAL CONTRIBUTIONS

4.1 Initial Facilities Capital Contributions. Each Party has made or will make (as applicable) the Capital Contributions described in this Section 4.1 (the “Initial Facilities Capital Contributions”).

(a) As of the execution of this Agreement, each Partner has contributed to the Company the amounts set forth below:

·	For the account of Oiltanking, one United States Dollar ($1.00);

·	For the account of TEPPCO, one United States Dollar ($1.00); and

·	For the account of Enterprise, one United States Dollar ($1.00).

(b) Solely to the extent that the Company does not have cash immediately available to satisfy same, the Partners will contribute cash in amounts equal to their allocable share (determined by relative Partnership Interests) of 100% of all amounts for costs and expenses incurred on behalf of the Company related to the feasibility study for TOPS, the formation of the Company and all amounts to be incurred by the Company to design, construct, install and place in service the Initial Facilities as necessary to timely and satisfactorily fulfill all of the Company’s obligations under the Throughput Agreements, which contributions will be made as necessary or appropriate subject to Section 4.1(d) (in the Construction Manager’s reasonable determination) to allow the Company to timely pay such amounts as they become due. An estimate of the contributions necessary or appropriate under this Section 4.1(b) is set forth on Schedule 3.

(c) If the Construction Manager determines from time to time in its reasonable discretion that any Capital Contribution described in Section 4.1(b) may be necessary or appropriate to timely complete the Initial Facilities, then the Construction Manager will send written notice (a “Capital Call Notice”) to the Partners specifying (i) the aggregate amount of such Capital Contribution reasonably and in good faith deemed necessary or appropriate by the Construction Manager and each Partner’s allocable share thereof, (ii) the actual expenditures incurred through the date of such notice, broken out by project or obligation and amounts set forth in the applicable Budget for the project or obligation for which the Capital Contribution is being requested, and (iii) the date by which such Capital Contributions must be made to the Company by the Partners (which date will not be less than ten Business Days from the date on which the Capital Call Notice is sent). Subject to Section 4.1(d), each Partner must promptly thereafter

contribute cash to the Company in an amount equal to such Partner’s allocable share of the amount of such Capital Contribution on or before the date specified in such Capital Call Notice.

(d) If a Capital Call Notice is delivered requesting Capital Contributions (i) for line item amounts exceeding those set forth in the applicable Budget by 10% or $2,500,000 or (ii) not provided for in a Budget and in excess of $2,500,000 (either of (i) or (ii), an “Unbudgeted Capital Call”), the Construction Manager must set forth in its Capital Call Notice a detailed explanation for the variance from the Budget. If any Partner reasonably and in good faith believes that the excess amounts so requested are (A) due to the gross negligence or willful misconduct (which expressly includes any intentional breach of a material provision contained in the Construction Agreement) of the Construction Manager or (B) not reasonably necessary or appropriate for completion of the Initial Facilities, such Partner may dispute the excess Capital Contribution so requested with written notice, stating the reason(s) for such belief (a “Capital Call Dispute Notice”), to the Construction Manager and the other Partners within 10 Business Days of receipt of the relevant Capital Call Notice (“Capital Call Dispute Period”). If a Partner does timely deliver a Capital Call Dispute Notice, such dispute (the “Capital Call Dispute”) shall be determined in accordance with Section 4.1(f).

(e) Notwithstanding the fact that a Partner has timely delivered a Capital Call Dispute Notice, such Partner will contribute to the Company the entire amount requested in such Capital Call Notice in accordance with the Capital Call Notice instruction.

(f) Resolution of Capital Call Disputes.

(i) Disputes as to Whether an Amount is Necessary. If a Capital Call Dispute Notice has been timely delivered and such Capital Call Dispute Notice alleges that an Unbudgeted Capital Call is not reasonably necessary or appropriate for completion of the Initial Facilities, then the Partners will refer such dispute to the Determining Engineer to resolve. The sole matter to be determined by the Determining Engineer in any such dispute is whether the Unbudgeted Capital Call is, or is not, reasonably necessary or appropriate for completion of the Initial Facilities. The Partners will use (and, if the Construction Manager is under the Control of a Partner, such Partner will cause the Construction Manager to use) commercially reasonable efforts to cooperate with the Determining Engineer so that the Determining Engineer may reach its decision as quickly as possible. In connection with the resolution of any such Capital Call Dispute, the Company will agree to indemnify the Determining Engineer to the extent reasonably requested by the Determining Engineer. All costs incurred by any Partner in connection with any such Capital Call Dispute will be for the account of such Partner. All amounts paid to the Determining Engineer in connection with any such Capital Call Dispute shall be paid by the Company. The determination of any such Capital Call Dispute by the Determining Engineer will be final and each Partner hereby waives its ability to appeal such determination, whether through resort to the courts or otherwise. If the resolution of the Capital Call Dispute provides that all or any portion of the Unbudgeted Capital Call was not reasonably necessary or

appropriate for completion of the Initial Facilities, the Partners shall instruct the Construction Manager to revise the Capital Call Notice accordingly, and to the extent that such distribution would not breach any of the Company’s material third party agreements (including loan agreements), the Company shall return such excess amounts contributed to the applicable contributing Partners.

(ii) Disputes as to Whether an Amount was Caused by the Construction Manager. If a Capital Call Dispute Notice has been timely delivered and such Capital Call Dispute Notice alleges that an Unbudgeted Capital Call is due to the gross negligence or willful misconduct (which expressly includes any intentional breach of a material provision contained in the Construction Agreement) of the Construction Manager, then such dispute will be resolved according to Section 16.5. If the resolution of the Capital Call Dispute provides that all or any portion of the Unbudgeted Capital Call was due to the gross negligence or willful misconduct of the Construction Manager, then the Company shall promptly take action to recover such funds from the Construction Manager, together with interest from the date of payment thereof as set forth in the Construction Agreement. To the extent that such distribution would not breach any of the Company’s material third party agreements (including loan agreements), the Company shall distribute all such recovered funds to the Partners that contributed funds with respect to the relevant Unbudgeted Capital Call.

(g) Each Capital Contribution made will be credited to the contributing Party’s Capital Account (other than any amounts returned pursuant to Section 4.1(f)).

4.2 Subsequent Contributions. No Party will be required to make any Capital Contributions other than the Initial Facilities Capital Contributions and any other Capital Contribution to which such Party has agreed in writing (including by approval of written resolutions). Except to the extent set forth in Article XV, no Party may make any Capital Contribution other than the Initial Facilities Capital Contributions unless such Capital Contribution has been approved by a Unanimous Non-Defaulting Interest.

4.3 Failure to Contribute.

(a) If a Party does not contribute by the required time all or any portion of a Capital Contribution such Party (the “Delinquent Party”) is required to make under Section 4.1 or to which such Party agreed, any one or more Non-Delinquent Partner may advance the entire amount of the Delinquent Party’s Capital Contribution that has not been contributed, with each Non-Delinquent Partner electing to participate in such advance making its share of such advance in proportion to its Partnership Interest (without taking into account the Partnership Interest of the Delinquent Party) or in such other percentages as the participating Partners may agree. Each Non-Delinquent Partner who makes such an advance on behalf of a Delinquent Party will have the right to designate the extent to which such advance will (x) constitute a loan to the Delinquent Party and/or (y) result in an immediate adjustment of the Partnership Interests of the Delinquent Party and the Non-Delinquent Partner making such election; provided, however, that if the advancing Non-Delinquent Partner does not notify the Company of

its election to have all, or any portion of, such advance treated as a loan to the Delinquent Party, in writing, at the time the advance is made, then such advance will automatically result in an immediate adjustment of the Partnership Interests.

(i) To the extent one or more Non-Delinquent Partners does not elect to have an advance made pursuant to Section 4.3(a) treated as a loan to the Delinquent Party, or affirmatively elects to have such advance result in an adjustment of the Partnership Interests, the Company will automatically adjust the Partnership Interest for each Partner to equal the percentage obtained by dividing (A) the Capital Contributions made by such Partner (including any Capital Contribution made by such Partner under this Section 4.3 multiplied by two and twenty-five hundredths (2.25); provided that the Delinquent Party shall forfeit from its Capital Contributions an amount equal to the amount of the Delinquent Party’s Capital Contribution that has not been contributed and that has not been designated as a loan multiplied by one and twenty-five hundredths (1.25)) by (B) the aggregate Capital Contributions made by all Partners (including all Capital Contributions made under this Section). Upon the adjustment of the Partnership Interests in the manner set forth in the preceding sentence, Exhibit A will be deemed to be amended to reflect such adjusted Partnership Interests. Notwithstanding the foregoing, the Delinquent Party will have the right to re-acquire the interest in question from the advancing Non-Delinquent Partner within 30 Days following the date on which such Partnership Interest adjustment is made by paying the entire amount advanced by such Non-Delinquent Partner in return for such adjustment, plus interest thereon at a rate equal to the lesser of (A) the maximum, lawful interest rate, compounded monthly, that is then-currently permitted under applicable Law, or (B) 12% per annum.

(ii) To the extent one or more Non-Delinquent Partners (the “Lending Partner,” whether one or more) elects to have an advance made pursuant to Section 4.3(a) constitute a loan to the Delinquent Party, such advance will have the following results (except to the extent otherwise agreed by the Lending Partner and the Delinquent Party, in each such Person’s sole discretion):

(A) the sum advanced will constitute a loan from the Lending Partner to the Delinquent Party and a Capital Contribution of that sum to the Company by the Delinquent Party pursuant to the applicable provisions of this Agreement;

(B) the principal balance of the loan and all accrued unpaid interest thereon (collectively, the “Obligation”) will be due and payable in whole no later than the tenth Business Day after the Day written demand requesting payment of the Obligation is made by the Lending Partner to the Delinquent Party; provided, however, that the Delinquent Party may prepay the Obligation in whole or in part at any time prior to the date due;

(C) the amount lent will bear interest at the Default Interest Rate from the date on which the advance is deemed made until the date on

which the loan, together with all interest accrued thereon and all costs and expenses associated therewith (“Costs”), is repaid to the Lending Partner;

(D) all distributions from the Company that otherwise would be made to the Delinquent Party (whether before or after dissolution of the Company) instead will be paid to the Lending Partner until the Obligation and any Costs have been paid in full to the Lending Partner (with payments being applied first to accrued and unpaid interest, second to Costs, and finally to principal);

(E) the Lending Partner will have the right, in addition to the other rights and remedies granted to it pursuant to this Agreement or available to it at Law or in equity, to take any action (including court proceedings and exercising the rights of a secured party under the Uniform Commercial Code of any applicable State) that the Lending Partner may deem appropriate to obtain payment from the Delinquent Party of the Obligation and all Costs; and

(F) initially, a loan by any Partner to another Partner as contemplated by this Section 4.3(a)(ii) will not be considered a Capital Contribution by the Lending Partner and will not increase the Capital Account balance of the Lending Partner. Notwithstanding the foregoing, if the principal and interest of any such loan have not been repaid within one year from the date of the loan, the Lending Partner, at any time thereafter by giving written notice to the Company, may elect to have the unpaid principal and interest balance of such loan transferred to and increase such Lending Partner’s Capital Account with a corresponding decrease in the Capital Account of the Partner on whose behalf such loan was made. Upon such transfer, the loan will be treated as a Capital Contribution and the Partnership Interest for each Partner will be automatically adjusted to equal the percentage obtained by dividing (A) the Capital Account of such Partner (including any Capital Contributions made on behalf of another Partner multiplied by two; provided that the Delinquent Party shall forfeit from its Capital Contributions an amount equal to the amount of the Delinquent Party’s Capital Contribution that has not been contributed and has not been designated as a loan) by (B) the aggregate Capital Accounts of all Partners (including all Capital Contributions made on behalf of other Partners). Upon the adjustment of the Partnership Interests in the manner set forth in the preceding sentence, Exhibit A will be deemed to be amended to reflect such adjusted Partnership Interests.

(b) Notwithstanding the rights of Non-Delinquent Partners described in Section 4.3(a), the Company, by a vote of a Majority Interest (where the Party in Default is not an Eligible Partner), will have the right to exercise the following remedies with respect to a Party in Default:

(i) the Company may at any time take such action (including court proceedings) as the Company may deem appropriate to obtain payment by the Delinquent Party of the portion of the Delinquent Party’s Capital Contribution that is in Default, along with all Costs and expenses associated with the collection of such Delinquent Party’s Capital Contribution; and

(ii) the Company may at any time exercise any other rights and remedies available at law or in equity.

(c) For purposes of Section 4.3(b) above the rights of the Lending Partner shall be pari passu as among the Company and the Eligible Partners.

4.4 Return of Contributions. No Partner is entitled (a) to the return of any part of any Capital Contributions (other than any preferential or disproportionate distributions to the extent such distributions are expressly required to be returned by this Agreement) or (b) 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 its Subsidiaries or of any other Partner. A Partner is not required to contribute or to lend any cash or property to the Company to enable the Company to return any other Partners’ Capital Contributions.

4.5 Capital Accounts. A separate capital account (“Capital Account”) will be established and maintained for each Party in accordance with the rules of Treasury Regulation section 1.704-1(b)(2)(iv) and the following terms and conditions:

(a) Increases and Decreases. Each Party’s Capital Account will be (i) increased by (A) the amount of cash or cash equivalents contributed by that Party to the Company as capital, (B) the Net Agreed Value of property contributed by that Party to the Company as capital, (C) the amount of any loans transferred by such Partner to its Capital Account pursuant to Section 4.3(a)(ii)(F) (contributions contemplated by subparagraphs (A), (B) and (C) will be referred to as “Capital Contributions”), and (D) allocations to that Party 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 (ii) will be decreased by (A) the amount of cash or cash equivalents distributed to that Party by the Company, (B) the Net Agreed Value of property distributed to that Party by the Company, and (C) allocations of Company losses and deductions (or items thereof), including losses and deductions described in Treasury Regulation section 1.704-1(b)(2)(iv)(g) (but excluding losses or deductions described in Treasury Regulation section 1.704-1(b)(4)(i) or (iii));

(b) Method for Determining Income, Gain Or Loss and Deductions. For purposes of computing the amount of any item of income, gain, loss or deduction to be reflected in the Parties’ Capital Accounts, the determination, recognition and classification of any such item will be the same as its determination, recognition and classification for federal income tax purposes (including any method of depreciation, cost recovery or amortization used for that purpose), provided that:

(i) All fees and other expenses incurred by the Company to promote the sale of (or to sell) any interest that can neither be deducted nor amortized under section 709 of the Code, if any, will, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and will be allocated among the Partners pursuant to Sections 5.1 and 5.2.

(ii) 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 will be made without regard to any election under section 754 of the Code which may be made by the Company 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 Company asset pursuant to 734(b) or 743(b) of the Code is required to be taken into account in determining Capital Accounts pursuant to Treasury Regulation section 1.704-1(b)(2)(iv)(m), the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

(iii) Any income, gain or loss attributable to the taxable disposition of any Company property will be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Company’s Carrying Value with respect to such property as of such date.

(iv) 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 will be determined as if the adjusted basis of such property on the date it was acquired by the Company was equal to the Agreed Value of such property on the date it was acquired by the Company. Upon an adjustment pursuant to Section 4.5(d) to the Carrying Value of any Company property subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery or amortization attributable to such property will 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 will be determined using any reasonable method that the Company may adopt.

(v) Any income of the Company that is exempt from federal income tax and not otherwise taken into account in computing Net Income or Net Loss will be added to such taxable income or loss.

(c) Impact of Succession in Interests. A Transferee will succeed to the Capital Account of the Transferor relating to the Partnership Interest so Transferred.

(d) Adjustments to Capital Accounts.

(i) Additional Partnership Interests. Consistent with the provisions of Treasury Regulation section 1.704-1(b)(2)(iv)(f), on an issuance of additional Partnership Interests for cash or Contributed Property or upon an adjustment of the Partner’s Capital Accounts pursuant to Section 4.3, the Capital Accounts of all Partners and the Carrying Value of each Company property immediately prior to such issuance or adjustment will be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Company 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 or adjustment and had been allocated to the Partners at such time pursuant to Section 5.1.

(ii) Adjustments Prior to a Distribution. In accordance with Treasury Regulation section 1.704-1(b)(2)(iv)(f), immediately prior to any distribution to a Partner of any Company property (other than a distribution of cash or cash equivalents that are not in redemption or retirement of a Partnership Interest), the Capital Accounts of all Partners and the Carrying Value of each Company property will be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Company 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 (which will be determined by a Majority Interest), and had been allocated to the Partners at such time, pursuant to Section 5.1.

(e) Non-Partner Parties. Notwithstanding anything to the contrary herein, if the Company has not been notified in writing of the existence of any non-Partner Party (i) the Company will not have any liability for maintaining such Party’s Capital Account and (ii) such Party will be responsible for all costs, expenses and other damages suffered by the Company and the other Parties by reason of such lack of notice.

4.6 Partner Parent Guarantees

As an inducement to each other Partner to enter into this Agreement and as security for the payment of Initial Facilities Capital Contributions, each of the Partners have caused their respective Affiliate guarantors to issue a guarantee of such Partner’s obligation to contribute Capital Contributions, and as a further inducement Oiltanking has issued its comfort letter to Enterprise and TEPPCO, true and correct copies of which are attached as Exhibit C.

ARTICLE V

ALLOCATIONS AND DISTRIBUTIONS

5.1 Allocations for Capital Account Purposes. For purposes of maintaining the Capital Accounts and in determining the rights of the Parties among themselves, the Company’s items of income, gain, loss and deduction (computed in accordance with Section 4.5(b)) will be allocated among the Parties for each taxable year (or portion thereof) as provided herein below.

(a) Net Income. All items of income, gain, loss and deduction taken into account in computing Net Income for such taxable period, determined after any special allocations required by Sections 5.1(c) through 5.1(j) have first been made, will be allocated to each Party in proportion to its respective Partnership Interests.

(b) Net Loss. All items of income, gain, loss and deduction taken into account in computing Net Loss for such taxable period, determined after any special allocations required by Sections 5.1(c) through 5.1(j) have first been made, will be allocated to each Party in proportion to its respective Partnership Interests.

(c) Nonrecourse Liabilities. For purposes of Treasury Regulation section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Company in excess of the sum of (i) the amount of Partnership Minimum Gain and (ii) the total amount of Nonrecourse Built-in Gain will be allocated among the Parties in accordance with their respective Partnership Interests.

(d) Partnership Minimum Gain Chargeback. Notwithstanding the other provisions of this Section 5.1, except as provided in Treasury Regulation section 1.704-2(f)(2) through (5), if there is a net decrease in Partnership Minimum Gain during such taxable period, each Party will be allocated items of Company 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) and (g)(2) and section 1.704-2(j)(2)(i), or any successor provisions. For purposes of this Section 5.1(d), each Party’s Adjusted Capital Account balance will be determined, and the allocation of income or gain required hereunder will be effected, prior to the application of any other allocations pursuant to this Section 5.1 with respect to such taxable period (other than an allocation pursuant to Section 5.1(h) or (i)).

(e) Chargeback of Minimum Gain Attributable to Partner Nonrecourse Debt. Notwithstanding the other provisions of this Section 5.1 (other than Section 5.1(d), except as provided in Treasury Regulation section 1.704-2(i)(4)), if there is a net decrease in Minimum Gain Attributable to Partner Nonrecourse Debt during such taxable period, any Party with a share of Minimum Gain Attributable to Partner Nonrecourse Debt at the beginning of such taxable period will be allocated items of Company 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 5.1, each Party’s Adjusted Capital Account balance will be determined and the allocation of income or gain required hereunder will be effected, prior to the application of any other allocations pursuant to this Section 5.1, other than Sections 5.1(d), (h) and (i), with respect to such taxable period.

(f) Qualified Income Offset. In the event any Party unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation section 1.704-1(b)(2)(ii)(d)(4) through (6) (or any successor provisions), items of Company income and gain will be specifically allocated to such Party 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 5.1(d) or 5.1(e).

(g) Gross Income Allocations. In the event any Party has a deficit balance in its Adjusted Capital Account at the end of such taxable period which is in excess of the sum of (i) the amount such Party is obligated to restore pursuant to any provision of this Agreement and (ii) the amount such Party is deemed obligated to restore pursuant to the penultimate sentences of Treasury Regulations sections 1.704-2(g)(1) and 1.704-2(i)(5), such Party will be specifically allocated items of Company gross income and gain in the amount of such excess as quickly as possible; provided that an allocation pursuant to this Section 5.1(g) will be made only if and to the extent that such Party would have a deficit balance in its Adjusted Capital Account after all other allocations provided in this Section 5.1 have been tentatively made for such taxable period as if this Section 5.1(g) was not in the Agreement.

(h) Nonrecourse Deductions. Nonrecourse Deductions for any such taxable period will be allocated to the Parties in proportion to their respective Partnership Interests. If a Majority Interest determines in the Eligible Partners’ good faith discretion that the Company’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 Company is authorized, upon notice to the Parties, to revise the prescribed ratio to the numerically closest ratio which does satisfy such requirements.

(i) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period will be allocated 100% to the Party that bears the Economic Risk of Loss for such Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation section 1.704-2(i) (or any successor provision). If more than one Party bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse Deductions attributable thereto will be allocated between or among such Parties ratably in proportion to their respective shares of such Economic Risk of Loss.

(j) Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to section 734(b) or 743(b) of the Code is required to be taken into account in determining Capital Accounts pursuant to Treasury Regulation section 1.704-1(b)(2)(iv)(m), the amount of such adjustment in the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of such asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Parties in the manner in which their Capital Accounts are required to be adjusted pursuant to such section of the Treasury Regulations.

5.2 Allocations for Tax Purposes.

(a) Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction which is recognized by the Company for federal income tax purposes will be allocated among the Parties in the same manner as its

correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 5.1.

(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 will be allocated for federal income tax purposes among the Parties as follows:

(i) (A) In the case of a Contributed Property, such items attributable thereto will be allocated among the Parties in the manner provided under section 704(c) of the Code and section 1.704-3(d) of the Treasury Regulations (i.e. the “remedial method”) 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 will be allocated among the Parties in the same manner as its correlative item of “book” gain or loss is allocated pursuant to Section 5.1.

(ii) (A) In the case of an Adjusted Property, such items will (1) first, be allocated among the Parties in a manner consistent with the principles of section 704(c) of the Code and section 1.704-3(d) of the Treasury Regulations (i.e. the “remedial method”) to take into account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations thereof pursuant to Section 4.5(d)(i) or (ii) and (2) second, in the event such property was originally a Contributed Property, be allocated among the Parties in a manner consistent with Section 5.2(b)(i)(A); and (B) any item of Residual Gain or Residual Loss attributable to an Adjusted Property will be allocated among the Parties in the same manner as its correlative item of “book” gain or loss is allocated pursuant to Section 5.1.

(c) For the proper administration of the Company, the Company will (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; provided, that such depreciation, amortization and cost recovery methods will be the most accelerated methods allowed under federal tax laws; (ii) make special allocations for federal income tax purposes of income (including gross income) or deductions; and (iii) amend the provisions of this Agreement as appropriate to reflect the proposal or promulgation of Treasury Regulations under section 704(b) or section 704(c) of the Code. The Company may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 5.2(c) only if such conventions, allocations or amendments are consistent with the principles of section 704 of the Code.

(d) The Company may determine to depreciate 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 unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation method and useful life applied to the Company’s common basis of such property, despite the inconsistency of such with Treasury Regulation section 1.167(c)-1(a)(6), or any successor provisions. If the Company

determines that such reporting position cannot reasonably be taken, the Company may adopt any reasonable depreciation convention that would not have a material adverse effect on the Partners.

(e) Any gain allocated to the Parties upon the sale or other taxable disposition of any Company asset will, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 5.2 be characterized as Recapture Income in the same proportions and the same extent as such Parties (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 Company for federal income tax purposes and allocated to the Parties in accordance with the provisions hereof will be determined without regard to any election under section 754 of the Code which may be made by the Company; provided, however, that such allocations, once made, will be adjusted as necessary or appropriate to take into account those adjustments permitted or required by sections 734 and 743 of the Code.

5.3 Requirement of Distributions. Subject to the provisions of Sections 5.6 and 12.2, the Company will distribute (within 30 Days following the end of each calendar month) its Available Cash to the Parties who were Record Holders as of the Record Date for such distribution, as provided in Section 5.4.

5.4 Sharing of Distributions. Except for preferential or disproportionate distributions to the extent expressly provided for in this Agreement (including those set forth in Sections 4.1(f)(ii) and 12.2), all distributions attributable to the Partnership Interests of the Company paid in cash, property, or equity ownership of the Company will be allocated and made to the Parties in proportion to their respective Partnership Interests.

5.5 Reserves. Before payment of any distributions, there may be set aside out of any Available Cash such sum or sums as a Unanimous Interest from time to time determines proper as a cash reserve or reserves to meet working capital, other obligations and contingencies, for repairing or maintaining any property of the Company, or for such other purpose as a Required Interest determines to be appropriate, except that no reserves shall be provided or be retained for any cost of the Company that will be capitalized; and a Required Interest may modify or abolish any such cash reserve in the manner in which it was created.

5.6 Distribution Restrictions. Unless consented to in writing by a Unanimous Interest, and subject to the provisions of Section 4.3, the Company will not distribute any of the Initial Facilities Capital Contributions until the completion of the construction and installation of the Initial Facilities, except to the extent that a Unanimous Interest agrees that the applicable portion of such Initial Facilities Capital Contributions is no longer needed to finance such construction and installation or the operations of the Company.

ARTICLE VI

MANAGEMENT OF THE PARTNERSHIP

6.1 Management by the Partners and Delegation of Authority. The business and affairs of the Company will be managed by or under the authority of the Partners in accordance with the Act, which Partners may act through their designated representatives. Except for situations in which the approval of the Partners is required by this Agreement or by non-waivable provisions of applicable Laws, a Required Interest will have broad discretion to, and may, authorize any committee constituted pursuant to Section 6.2 or any officer or other agent (including the Operator and the Construction Manager) to act on behalf of the Company or to make any determination on behalf of the Company. At a meeting of the Partners at which a quorum is present (in person or by proxy), the affirmative vote of a Majority Interest will be the act of the Partners or any committee unless a different Required Interest is required by a non-waivable provision of the Act or any express provision of this Agreement. Where the Required Interest for a particular action, determination or other matter with respect to the Company, the Partners or any committee formed hereunder is not expressly specified herein, a Majority Interest shall be the Required Interest with respect to such action, determination or other matter.

6.2 Committees.

(a) For organizational purposes, the Partners shall form a management committee of the Partners (the “Management Committee”) responsible for the planning, oversight and approval of the policies and strategies of the Company and any other actions not expressly delegated to another committee, body, officer or other representative of the Company (including Construction Manager or Operator) or otherwise retained or reserved for the Partners under this Agreement. At any time after the date hereof, the Partners may form one or more other committees of the Partners to be responsible for planning, oversight, control and approval over such matters as delegated to such committee by the Partners. Each Partner is entitled to representation on every committee established hereunder in proportion to its respective Partnership Interest and each Partner will appoint in writing one (or more) of its duly authorized agents to act for the Partner on each committee of the Partners. One such agent(s) of each Partner will be given the authority by such Partner to vote on behalf of the Partner on any issue within the committee’s responsibility. The collective representatives of each Partner on a committee will be entitled to one vote (or a fraction thereof) per percent (or fraction thereof) of Partnership Interest held by such Partner, as reflected in the transfer records of the Company. Any person may serve as a representative for more than one Partner.

(b) Each Partner is entitled to appoint the Chairman of the Management Committee in alternating years; provided such Partner holds at least a twenty percent (20%) Partnership Interest. During the first one-year period of this Agreement, Oiltanking shall select the Chairman, during the second one-year period, TEPPCO shall select the Chairman, and during the third one-year period Enterprise shall select the Chairman. For the purposes of this paragraph, each Partner and its Affiliates who are Partners shall be treated as a single Partner; provided, however, that Enterprise and TEPPCO shall not be treated as Affiliates for the purposed of this Section 6.2(b).

(c) Each Partner will appoint at least one Vice President or a more senior officer of the Partner or its Affiliates and one alternate to serve on the Management Committee. Each Partner will, absent extenuating circumstances, use commercially reasonable efforts to have such senior representative serve on the Management Committee for at least two consecutive years.

6.3 Authority of Partners and Committees.

(a) With respect to conflicts or disagreements between and among any committees, the Management Committee will have ultimate decision-making authority. The Partners and the committees will act through the Company’s officers, employees, representatives, agents and designees to whom authority has been expressly delegated. No Partner will have individual authority to bind the Company unless such is expressly delegated in writing, conferred upon it pursuant to this Agreement or by action of the Company or a duly authorized committee, body, officer or other representative. All actions required by this Agreement to be taken or approved by the Partners will be pursuant to resolutions approved or consented to by the Partners in accordance with Article VII (including the majority and unanimous approval requirements set forth in Sections 6.1 and 7.2).

(b) Unless otherwise expressly delegated in writing or provided by this Agreement and subject to Section 7.2, the Partners hereby delegate to the Management Committee as a group the authority, with respect to the Company, to authorize and approve the following, or, with respect to matters to be authorized or approved by Subsidiaries of the Company, to determine how the Company will vote as a member of such Subsidiary, with respect to the following:

(i) authorizing any Throughput Agreement;

(ii) (A) entering into any credit agreement, indenture or similar agreement, (B) entering into any employment agreement, consulting agreement or other services agreement with Affiliates or employees of Affiliates of any of the Partners or (C) borrowing money or making draws under any such previously approved credit agreement, indenture or similar agreement for the purpose of funding authorized transactions;

(iii) approving all Budgets, including any annual operating and capital expenditures budgets;

(iv) authorizing a transaction (or series of related transactions) involving a lease or similar arrangement;

(v) utilizing for other than Company purposes any material asset (or assets) of the Company;

(vi) acquiring or disposing of any asset (or assets) of the Company or its Subsidiaries;

(vii) authorizing a transaction (or series of related transactions) which involves acquiring, constructing or otherwise obtaining any pipeline, lateral or extension, including any Lateral, or any pumping, expansion or other facilities;

(viii) authorizing material transactions the nature of which are not in the ordinary course of business of the Company;

(ix) issuing additional equity interests in any Subsidiary of the Company;

(x) instituting or settling litigation, arbitration, or similar proceedings against any Partner;

(xi) entering into any contract, agreement or other undertaking that obligates or commits the Company or any of its Subsidiaries to incur expenditures;

(xii) authorizing any Interested Partner Transaction;

(xiii) permitting a Partner to dissociate;

(xiv) waiver, amendment, termination (other than by expiration of the term thereof) or other modification of the Construction Agreement (or any successor agreement) or the Operating Agreement (or any successor agreement); provided, however, that for purposes of this Section 6.3(b)(xiv), if any Partner or its Affiliate would be replaced as an operator or construction manager as a result of such termination, such Partner will not be entitled to vote on such termination; further provided, that the vote or consent of such Partners not terminated (to the extent such Partners are eligible to vote on or consent to such matter) will be sufficient to take such actions under this Section even if the Partnership Interests held by such Partners is less than a Majority Interest;

(xv) permitting dissolution and liquidation; and

(xvi) permitting the merger, consolidation, participation in a share exchange or other statutory reorganization of the Company with, or sale of all or substantially all of the assets of the Company or any of its Subsidiaries to, any Person.

An act of the Management Committee will occur only by the affirmative vote or written consent of the applicable Required Interest specified in this Agreement, including the Majority Interest approval requirements set forth in Section 6.1 and other Partnership Interest approval requirements otherwise set forth in this Agreement, and to the same extent as such Required Interests apply to the Partners.

(c) Management Committee approval of or agreement to any matter specified in Section 6.3(b)(i) (including as to whether the Company should accept any particular quality of Oil in a proposed Throughput Agreement) shall be granted or withheld based only upon such Partner’s good faith belief that such approval or agreement, or the

withholding of such approval or agreement, is in the best interest of the Company. Approval of or agreement to any other matter required under this Agreement may be withheld by any Partner for any reason whatsoever, in each Partner’s sole and absolute discretion.

6.4 Officers.

(a) The Management Committee may designate one or more Persons to fill one or more officer positions of the Company to perform such duties as specified by the Management Committee. Such officers may include President, Vice President, Treasurer, Assistant Treasurer, Secretary and Assistant Secretary. No officer need be a resident of the State of Delaware. The Management Committee may assign titles to particular officers. Each officer will hold office until his successor will be duly designated and will qualify to hold such office for a two-year term, or, if earlier, until his death or until he will resign or will have been removed in the manner hereinafter provided. Any number of offices may be held by the same Person. The salaries or other compensation, if any, of the officers and agents of the Company may be fixed from time to time by the Partners.

(b) Any officer may resign as such at any time. Such resignation will be made in writing and will take effect at the time specified therein, or if no time be specified, at the time of its receipt by the Company. The acceptance of a resignation will not be necessary to make it effective, unless expressly so provided in the resignation. Any officer may be removed as such, either with or without cause, by the Management Committee; provided, however, that such removal will be without prejudice to the contract rights, if any, of the officer so removed. Designation of an officer will not of itself create contract rights. Any vacancy occurring in any office of the Company may be filled by the Management Committee.

6.5 Duties of Officers. Each officer will devote such time, effort, and skill to the Company’s business affairs as he or she deems necessary and proper for the Company’s welfare and success. The Partners expressly recognize that the officers have substantial other business relationships and activities with Persons other than the Company.

6.6 No Duty to Consult. Except as otherwise provided herein or by applicable law, neither the Company nor its duly appointed agents, designees or representatives (including the Operator and the Construction Manager) or the officers of the Company will have a duty or obligation to consult with or seek the advice of the Partners on any matter relating to the day-to-day business affairs of the Company duly delegated to such Persons; provided, however, that such Persons will not be restricted from consulting with or seeking the advice of the Partners.

6.7 Reimbursement. Except as otherwise provided in Article IV and except for expenses incurred by the Partners in connection with preparation of this Agreement and the Related Agreements, all expenses incurred with respect to the organization, operation and management of the Company will be borne by the Company.

6.8 Partners and Affiliates Dealing With the Company. Subject to any approval required under Article VII, the Company may appoint, employ, contract, or otherwise deal with any Person, including Partners, Affiliates of the Partners, other Persons with whom the Partners are otherwise related, and with Persons which have a financial interest in a Partner or in which a Partner has a financial interest, for transacting Company business, including any acts or services for the Company as the Partners of any committee, officer or other representative with the proper authority may approve.

6.9 Insurance. The Operator will provide the applicable insurance coverages described on Schedule 2 for the benefit of the Company and the Partners. The costs of the insurance coverages described on Schedule 2 which are obtained by the Operator will automatically be included in the applicable operating budget for the Company without the necessity of approval by the Partners. All insurance policies provided by the Operator will provide that the insurers waive their right of subrogation against the Partners, the Affiliates of each of the foregoing and other indemnitees.

7.4 Voting List. The Secretary or Assistant Secretary of the Company or the designated Partner representative on the committee for the maintenance of the committee’s records will make, at least five Days before each meeting of Partners or the applicable committee, a complete list of the Partners or their representatives, as the case may be, entitled to vote thereat or any adjournment thereof, arranged in alphabetical order, with the address of and the Partnership Interest held or represented by each, which list, for a period of ten Days prior to such meeting, will be kept on file at the registered office or principal place of business of the Company and will be subject to inspection by any Partner or Partner representative at any time

during usual business hours. Such list will also be produced and kept open at the time and place of the meeting and will be subject to the inspection of any Partner or Partner representative during the whole time of the meeting. The original Company records will be prima facie evidence as to who are the Partners or their representatives entitled to examine such list or transfer records or to vote at any meeting of the Partners or the Management Committee. Failure to fully comply with the requirements of this Section 7.4 will not affect the validity of any action taken at the meeting.

7.5 Proxies. A Partner or its representative may vote either in person or by proxy executed in writing by the Partner or Partner representative. A telegram, telex, cablegram or similar transmission by the Partner or Partner representative or a photographic, photostatic, facsimile or similar reproduction of writing executed by the Partner or Partner representative will be treated as an execution in writing for purposes of this Section 7.5. Proxies for use at any meeting of the Partners or committee of the Company or in connection with the taking of any action by written consent will be filed with the Company before or at the time of the meeting or execution of the written consent, as the case may be. All proxies will be received and taken charge of and all ballots will be received and canvassed by an inspector or inspectors appointed by the President or a Vice President of the Company who will decide all questions touching upon the qualification of voters, the validity of the proxies, and the acceptance or rejection of votes.

7.6 Votes. Each Partner or Partner representative will be entitled to one vote (or a fraction thereof) per percent (or fraction thereof) of Partnership Interest held by such Partner, as reflected in the transfer records of the Company; provided, however, that for purposes of determining a quorum or a Required Interest the Partnership Interest of any relevant Partner will not be counted and such interest will be apportioned by interest among the remaining Partners as applicable if the relevant Partner is not eligible to vote on or consent to the applicable matter for any reason, including because the relevant Partner is in Default, or is not deemed to be a Substituted Partner; provided further, however, that no Partner will be required to make any Capital Contribution, other than an Initial Facilities Capital Contribution, if such Partner did not vote to approve such Capital Contribution in accordance with Section 4.2. Except to the extent required by applicable Laws, a Party in Default is not eligible to vote on or consent to any matter during the existence and continuation of such Default.

7.7 Conduct of Meetings. All meetings of the Partners will be presided over by the chairman of the meeting, who will be, in order of priority, the President, Vice President or other appropriate officer of the Company. All meetings of any committee of the Company will be presided over by the then acting Chairman or Vice-Chairman of the Committee or, in such person’s absence, such other person designated by the Committee. The chairman of any meeting of the Partners or committee of the Company will determine the order of business and the procedure at the meeting, including regulation of the manner of voting and the conduct of discussion.

7.8 Action by Written Consent.

(a) Except as otherwise provided by applicable Laws, any action required or permitted to be taken at any meeting of Partners or committee of the Company may be taken without a meeting, and without a vote, if a consent or consents in writing, setting

forth the action so taken, is signed by the holder or holders or representatives of not less than the minimum of Required Interests that would be necessary to take such action at a meeting at which the holders of all Partnership Interests eligible to vote on the action were present and voted. To the extent required by Law, every written consent will bear the date of signature of each Partner or Partner representative who signs the consent. To the extent required by law, no written consent will be effective to take the action that is the subject of such consent unless, within 60 Days after the date of the earliest dated consent delivered to the Company in the manner required by this Section 7.8, a consent or consents signed by the holder or holders of not less than the minimum Required Interest that would be necessary to take the action that is the subject of the consent are delivered to the Company by delivery to its registered office or its principal place of business. Delivery will be by hand or certified or registered mail (return receipt requested) to the Company’s principal place of business and will be addressed to the Secretary of the Company. A telegram, telex, cablegram or similar transmission by a Partner or Partner representative, or a photographic, photostatic, facsimile or similar reproduction of a writing signed by a Partner or Partner representative, or an e-mail, or other electronic communication bearing an electronic or digital signature, will be regarded as signed by the Partner or Partner representative for purposes of this Section 7.8. Prompt written notice of the taking of any action by the Partners or committees of the Company without a meeting by less than a Unanimous Interest will be given to those Partners or Partner representatives who did not consent in writing to the action.

(b) The Record Date for determining Partners or their representatives entitled to consent to an action in writing without a meeting will be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Company.

7.9 Resolution of Management Disputes. If a Management Dispute occurs, it will be subject to the provisions of this Section 7.9, notwithstanding any other provision of this Agreement to the contrary. Upon the written request by any Partner served on the Company and each of the other Partners within 10 Days following any vote of the Partners resulting in a Management Dispute, the senior management-level representatives of the Partners shall meet in an effort to attempt to resolve the Management Dispute. For purposes of this Section 7.9, a “Management Dispute” means any matter which, after having been duly presented for approval of the Partners, is not approved by a Required Interest, but which receives the affirmative vote of a Majority Interest. If the senior management-level representatives of the Partners are unable, in good faith, to resolve in its entirety any Management Dispute, then such Management Dispute will remain unresolved.

7.10 Records. An officer of the Company or a designated Partner representative will be responsible for maintaining the records of the Company, including keeping minutes at the meetings of the Partners or committees of the Company and the filing of consents in the records of the Company.

ARTICLE VIII

INDEMNIFICATION

8.1 Right to Indemnification. Subject to the limitations and conditions as provided herein or by applicable Laws, each Person who was or is made a party or is threatened to be made a party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative (hereinafter a “Proceeding”), or any appeal in such a Proceeding or any inquiry or investigation that could lead to such a Proceeding, by reason of the fact that he or she, or a Person of whom he or she is the legal representative, is or was a Partner, a member of a committee of the Company or an officer of the Company, or while such a Person is or was serving at the written request of the Company (as approved by a Majority Interest of the Partners) as a director, officer, partner, venturer, proprietor, member, trustee, employee, agent, or similar functionary of another foreign or domestic general partnership, corporation, limited partnership, joint venture, limited liability company, sole proprietorship, trust, employee benefit plan or other enterprise, will be indemnified by the Company to the extent such Proceeding or other above-described process relates to any such above-described relationships with, status with respect to, or representation of any such Person, to the fullest extent permitted by the Act, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than said Laws permitted the Company to provide prior to such amendment) against judgments, penalties (including excise and similar taxes and punitive damages), fines, settlements and reasonable expenses (including attorneys’ fees) actually incurred by such Person in connection with such Proceeding, and indemnification under this Section 8.1 will continue as to a Person who has ceased to serve in the capacity which initially entitled such Person to indemnity hereunder for any and all liabilities and damages related to and arising from such Person’s activities while acting in such capacity; provided, however, that no Person will be entitled to indemnification under this Section 8.1 in the event the Proceeding involves acts or omissions of such Person which constitute an intentional breach of this Agreement or gross negligence or willful misconduct on the part of such Person or if such Person was acting, willfully and in bad faith, otherwise than on behalf of the Company or in accordance with this Agreement or the Related Agreements. The rights granted pursuant to this Article VIII will be deemed contract rights, and no amendment, modification or repeal of this Article VIII will have the effect of limiting or denying any such rights with respect to actions taken or Proceedings arising prior to any such amendment, modification or repeal. It is expressly acknowledged that the indemnification provided in this Article VIII could involve indemnification for negligence or under theories of strict liability.

8.2 Indemnification of Others. The Company may (upon approval of a Unanimous Interest) indemnify, and advance expenses to, (a) Persons who are not or were not a Partner, including officers, employees or agents of (i) any Partner or its Affiliate and (ii) the Company, and (b) those Persons who are or were serving at the written request of the Company (as approved by a Majority Interest) as a manager, director, officer, partner, venturer, proprietor, member, trustee, employee, agent or similar functionary of another foreign or domestic general partnership, corporation, limited partnership, joint venture, limited liability company, sole proprietorship, trust, employee benefit plan or other enterprise against any liability asserted against such Person and incurred by such Person in such a capacity or arising out of his status as

such a Person to the same extent that it may indemnify and advance expenses to a Partner under this Article VIII.

8.3 Advance Payment. Any right to indemnification conferred in Section 8.1 will include a limited right to be paid or reimbursed by the Company for any and all reasonable expenses as they are incurred by a Person for whom indemnification under Section 8.1 is available and who was, or is threatened, to be made a named defendant or respondent in a Proceeding in advance of the final disposition of the Proceeding and without any determination as to such Person’s ultimate entitlement to indemnification; provided, however, that the payment of such expenses incurred by any such Person in advance of final disposition of a Proceeding will be made only upon delivery to the Company of a written affirmation by such Person of his good faith belief that he has met the requirements necessary for indemnification under this Article VIII and a written undertaking, by or on behalf of such Person, to promptly repay all amounts so advanced if it will ultimately be determined that such indemnified Person is not entitled to be indemnified under this Article VIII or otherwise.

8.4 Appearance as a Witness. Notwithstanding any other provision of this Article VIII, the Company may pay or reimburse expenses incurred by any Person for whom indemnification is available pursuant to this Article VIII in connection with such Person’s appearance as a witness or other participation in a Proceeding relevant to the Company at a time when he is not a named defendant or respondent in the Proceeding.

8.5 Nonexclusivity of Rights. The right to indemnification and the advancement and payment of expenses conferred in this Article VIII will not be exclusive of any other right which a Person indemnified pursuant to Sections 8.1 and 8.2 may have or hereafter acquire under any Laws, this Agreement, or any other agreement, vote of Partners or otherwise; provided that any Person that is indemnified hereunder must promptly reimburse the Company up to such indemnified amounts to the extent such Person also recovers such costs from another Person. All indemnity obligations will first be satisfied by insurance proceeds (if any) and next by the assets of the Company.

8.6 Insurance; Appointment of Counsel. The Company may purchase and maintain indemnification insurance, at its expense, to protect itself and any Person from any expenses, liabilities, or losses that may be indemnified under this Article VIII. The Company may elect to engage competent counsel to assume control of the defense of any Proceeding for which it may or must provide indemnity hereunder.

8.7 Partner Notification. Any Person requesting indemnification hereunder must give the Company written notice of the claim within 30 Days of becoming aware of such claim or five Business Days prior to the date on which a response to such claim is due, if earlier than 30 Days; provided, that failure to give such notice shall not preclude indemnification unless the Company is materially prejudiced by such failure. All claims for indemnification and any indemnification of or advance of expenses to any Person entitled to be indemnified under this Article VIII will be reported in writing to the Partners with or before the notice or waiver of notice of the next Partners’ meeting or with or before the next submission to Partners of a consent to action without a meeting and, in any case, within the 3-month period immediately following the date the indemnification or advance was made.

8.8 Savings Clause. If this Article VIII or any portion hereof will be invalidated on any ground by any court of competent jurisdiction, then the Company will nevertheless indemnify and hold harmless any Person for whom indemnification is available under Section 8.1 as to costs, charges and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative to the full extent permitted by any applicable portion of this Article VIII that will not have been invalidated and to the fullest extent permitted by applicable Laws.

8.9 Scope of Indemnity. For the purposes of this Article VIII, references to the “Company” include all constituent entities, whether corporations or otherwise, absorbed in a consolidation or merger as well as the resulting or surviving entity. Thus, any Person for whom indemnity or advances are available under this Article VIII will stand in the same position under the provisions of this Article VIII with respect to the resulting or surviving entity as he would have if such merger, consolidation, or other reorganization never occurred.

ARTICLE IX

TAXES

9.1 Tax Returns. The Company will cause to be prepared and filed all necessary federal and state income tax returns for the Company, including making the elections described in Section 9.2.

Neither the Company nor any Partner may make an election for the Company to be excluded from the application of the provisions of subchapter K of chapter 1 of subtitle A of the Code or any similar provisions of applicable state law, and no provision of this Agreement will be construed to sanction or approve such an election.

9.3 Tax Matters Partner. The Company will select one of the Partners as the “Tax Matters Partner” of the Company pursuant to section 6231(a)(7) of the Code. The Tax Matters Partner will take such action as may be necessary to cause each Partner to become a “notice

partner” within the meaning of section 6223 of the Code and will inform each Partner of all significant matters that may come to its attention in its capacity as Tax Matters Partner by giving notice thereof on or before the fifth Business Day after becoming aware thereof and, within that time, will forward to each other Partner copies of all significant written communications it may receive in that capacity. The Tax Matters Partner may not take any action contemplated by sections 6222 through 6232 of the Code without the consent of a Unanimous Interest, but this sentence does not authorize the Tax Matters Partner to take any action left to the determination of an individual Partner under sections 6222 through 6232 of the Code. The initial Tax Matters Partner will be Enterprise. The Tax Matters Partner may be replaced by a Majority Interest (with respect to which the Tax Matters Partner will be an “Eligible Partner” unless an Affiliate of the Tax Matters Partner is not serving as the Operator).

ARTICLE XI

BANKRUPTCY OF A PARTNER

11.1 No Dissociation Upon Bankruptcy. Notwithstanding any provision herein or in the Act to the contrary, a Party becoming a Bankrupt Partner will not result in its dissociation under Section 15-601 of the Act unless all of the other Partners so elect at the time such Partner becomes a Bankrupt Partner: provided, however, that the Partners agree that a dissociation caused by any such election of the other Partners under this Section 11.1 shall not be deemed “wrongful” and, as a result, shall not trigger any of the remedies set forth in Section 3.9 (a) – (d). If all of the other Partners so elect for a Bankrupt Partner to be dissociated, the Company will not be dissolved or wound up and the provisions of Subchapter VI and VII of the Act shall apply.

11.2 Bankrupt Partners. If any Party becomes a Bankrupt Partner, the Company, by approval of at least a Majority Interest or, if the Company does not exercise the relevant option, the non-Bankrupt Partners which desire to participate, will have the option, exercisable by notice from the Company or the Partners, as the case may be, to the Bankrupt Partner (or its representative) at any time prior to the 180th Day after receipt of notice of the occurrence of the event causing it to become a Bankrupt Partner, to buy, and, on the exercise of this option, the Bankrupt Partner or its representative will sell, its Partnership Interest. The purchase price will be an amount equal to the Fair Market Value thereof determined by agreement by the Bankrupt Partner (or its representative) and the potential purchaser; however, if those Persons do not agree on the Fair Market Value on or before the 90th Day following the date of receipt by such potential purchaser of notice of the occurrence of the event causing the Partner to become a Bankrupt Partner, either such Person, by written notice to the other, may require the determination of Fair Market Value to be made by an independent Appraiser specified in such notice. If the Person receiving that notice objects on or before the tenth Day following receipt to the independent Appraiser designated in that notice, and those Persons otherwise fail to agree on an independent Appraiser, either such Person may petition the United States District Judge for the Southern District of Texas sitting in Harris County, Texas, then senior in active service to

designate an independent Appraiser, whose determination of the independent Appraiser, however designated, is final and binding on all parties. The Bankrupt Partner and the potential purchaser each will pay one-half of the costs of the appraisal and court costs in appointing an Appraiser (if any). If the potential purchaser then elects, within ten Days after the Fair Market Value has been decided by agreement or by an independent Appraiser, to exercise the purchase option, the purchasing Person will pay the Fair Market Value as so determined in cash on closing. The payment to be made to the Bankrupt Partner or its representative pursuant to this Section 11.2 is in complete liquidation and satisfaction of all the rights and interest of the Bankrupt Partner and its representative (and of all Persons claiming by, through, or under the Bankrupt Partner and its representative) in and in respect of the Company, including any Partnership Interest, any rights in specific Company property, and any rights against the Company or its Subsidiaries and its officers, agents, and representatives and (insofar as the affairs of the Company are concerned) against the Partners.

ARTICLE XII

DISSOLUTION, LIQUIDATION, AND TERMINATION

(b) the consent of a Unanimous Interest;

(d) any event resulting in only one remaining Partner.

Each Partner expressly agrees (i) that the bankruptcy or dissociation of a Partner or any other event described in Section 15-801 of the Act will not cause or result in the dissolution of the Company and (ii) that it will not, and it expressly waives its right to, apply to the Delaware Court of Chancery for a decree of dissolution under Section 15-801(5) of the Act.

12.2 Liquidation and Termination. Subject to Sections 3.4, 3.5 and 7.6, upon dissolution of the Company, a representative of the Company selected by a Majority Interest will act as a liquidator or may appoint one or more Partners as liquidator (“Liquidator”). The Liquidator will proceed diligently to wind up the affairs of the Company and make final distributions as provided herein and in the Act. The costs of liquidation will be borne as a Company expense. Until final distribution, the Liquidator will continue to operate the Company properties for a reasonable period of time to allow for the sale of all or a part of the assets thereof with all of the power and authority of the Partners. The steps to be accomplished by the Liquidator are as follows:

(a) as promptly as possible after dissolution and again after final liquidation, the Liquidator will cause a proper accounting to be made of the Company’s assets, liabilities, and operations through the last Day of the calendar month in which the dissolution occurs or the final liquidation is completed, as applicable;

(b) the Liquidator will cause any notices required by law to be mailed to each known creditor of and claimant against the Company in the manner described by such law;

(c) subject to the terms and conditions of this Agreement and the Act (especially section 15-803), the Liquidator will distribute the assets of the Company in the following order:

(i) the Liquidator will pay, satisfy or discharge from Company funds all of the debts, liabilities and obligations of the Company, including all expenses incurred in liquidation 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); provided, however, such payments will not include any Capital Contributions described in Article IV or any other obligations in favor of the Partners created by this Agreement other than a loan made pursuant to any provision;

(ii) the Liquidator will pay, satisfy or discharge from Company funds all of the advances and loans (but not Capital Contributions) made to the Company by Partners, as described in Section 4.5; and

(iii) all remaining assets of the Company will be distributed to the Partners as follows:

(A) the Liquidator may sell any or all Company property, including to one or more of the Partners; provided that (x) any such sale to a Partner is made on an arms length basis under terms which are in the best interest of the Company and (y) to the extent that any Partner has participated in an Expansion Option under Section 15.3, the Liquidator will hire an independent Appraiser to attribute (on the basis of its then-existing Fair Market Value) the proceeds from the sale of the Company property between each respective Expansion Project for which a Payout Amount has not been fully received by the Participating Partners, and all other assets of the Company (such value for each respective Expansion Project, the “Expansion Liquidation Value”) and the Liquidator will repay any Partners’ Expansion Option loan pursuant to Section 15.3, but only to the extent that there is any Expansion Liquidation Value allocated to the corresponding Expansion Project, and any resulting gain or loss from each sale will be computed and allocated to the Capital Accounts of the Partners on a pro rata basis in accordance with each of their respective Partnership Interests;

(B) with respect to all Company property that has not been sold, the fair market value of that property (as determined by the Liquidator using any method of valuation as it, using its best judgment, deems reasonable) will be determined and the Capital Accounts of the Partners will 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 Partners if there were a taxable disposition of that property for such fair market value of that property on the date of distribution; and

(C) Company property will be distributed among the Partners ratably in proportion to each Partner’s Partnership Interest;

All distributions in kind to the Partners will be made subject to the liability of each distributee for costs, expenses, and liabilities theretofore incurred or for which the Company has committed prior to the date of termination and those costs, expenses, and liabilities will be allocated to the distributee pursuant to this Section 12.2. The distribution of cash and/or property to a Partner in accordance with the provisions of this Section 12.2 constitutes a complete return to the Partner of its Capital Contributions and a complete distribution to the Partner of its Partnership Interest and all the Company’s property. To the extent that a Partner returns funds to the Company, it has no claim against any other Partner for those funds.

12.3 Provision for Contingent Claims.

(a) The Liquidator will make a reasonable provision to pay all claims and obligations, including all contingent, conditional or unmatured claims and obligations, actually known to the Company but for which the identity of the claimant is unknown; and

(b) If there are insufficient assets to both pay the creditors pursuant to Section 12.2(c)(i) and to establish the provision contemplated by Section 12.3(a), the claims will be paid as provided for in accordance to their priority, and, among claims of equal priority, ratably to the extent of assets therefor.

12.4 Deficit Capital Accounts. Notwithstanding anything to the contrary contained in this Agreement, and notwithstanding any custom or rule of law to the contrary, a deficit, if any, in the Capital Account of any Partner resulting from or attributable to any adjustments, allocations, losses, deductions, distributions or similar events, including deductions and losses of the Company (including non-cash items such as depreciation) or distributions of money pursuant to this Agreement to all Partners ratably in proportion to their respective Partnership Interests, upon the dissolution and winding up of the Company will not be an asset of the Company and no such Partner will be obligated to contribute any amounts to the Company to bring the balance of such Partner’s Capital Account to zero.

(e) any amendment that would materially and adversely affect the rights of any type or class of Partnership Interests in relation to other types or classes of Partnership Interests requires the approval of the holders of at least a majority of the Partnership Interests of such class or type of Partnership Interest; and

The Company will be entitled to recognize the exclusive right of a Person registered on its books as the owner of the indicated Partnership Interest and will not be bound to recognize any equitable or other claim to or interest in such Partnership Interest on the part of any Person other than such registered owner, whether or not it will have express or other notice thereof, except as otherwise provided by Law.

ARTICLE XV

OTHER PARTNER AGREEMENTS AND OBLIGATIONS

15.1 Facilities Other than Initial Facilities. No Party will, or will permit any of its Affiliates to, directly or indirectly, enter into any agreement to construct or otherwise consummate any transaction involving the construction of any Lateral (a “Lateral Opportunity”) until such Lateral Opportunity has been rejected or otherwise forfeited by the Company and the Partners, as applicable, in accordance with this Section 15.1.

(a) Any Partner may propose that the Company undertake a Lateral Opportunity by delivering written notice (a “Lateral Opportunity Notice”) to the Company and each of the other Partners, which Lateral Opportunity Notice would include the proposed terms and conditions of such transactions and reasonably sufficient operational and financial information and other details to allow such Partners to make a reasonably informed decision with respect to such Lateral Opportunity. If a Unanimous Interest does not approve the Lateral Opportunity and deliver notice thereof in writing within 30 Days after the Company receives the Lateral Opportunity Notice that the Company should undertake such project on the terms and conditions set forth in the applicable Lateral Opportunity Notice, any Partner voting in favor of such project will have the right to pursue such project (a “Rejected Lateral Opportunity”) on the terms and conditions set forth in the applicable Lateral Opportunity Notice and own any assets related thereto in the proportion that such Partner’s Partnership Interest is to the Partnership Interest of all Partners that had (i) voted in favor of such project and (ii) elected to participate in the Rejected Lateral Opportunity by giving written notice of such intent to the Company within 50 Days after the Company received the relevant Lateral Opportunity Notice. In such event, the Partners (directly or through their Affiliates) desiring to pursue such Rejected Lateral Opportunity will be free for a period of 60 Days after such 50-Day period to enter into definitive agreements, if any, or otherwise consummate the transactions contemplated by the applicable Lateral Opportunity Notice on the terms and conditions set forth in the applicable Lateral Opportunity Notice without further obligation to any Partners or the Company; provided that following such 60-Day period such Partners (and, to the extent covered by this Section 15.1, their applicable

Affiliates) may not enter into definitive agreements, if any, or otherwise consummate the transactions with respect to a Rejected Lateral Opportunity without again offering the same to the Company in accordance with this Section 15.1.

(b) No Partner will have any obligation or duty to the Company or the other Partners with respect to any Rejected Lateral Opportunity to the extent it is covered by definitive agreements entered into, or otherwise consummated, by such Partners or their applicable Affiliates after compliance with this Section 15.1 or with respect to any modification, renewal or extension of the terms of such definitive agreements with respect to any such Rejected Lateral Opportunity. Except as set forth in this Section 15.1, the construction, operation, maintenance and ownership of each such Rejected Lateral Opportunity project will not be governed or affected by this Agreement, but will be governed by the contractual and other arrangements established by the Partners (or their Affiliates) participating in such project; provided, that no Partner may vote against or refuse to consent to the interconnection of any such Rejected Lateral Opportunity project with TOPS unless such Partner reasonably and in good faith believes that such interconnection would materially damage TOPS or the Company.

(c) Any Partner that delivers a Lateral Opportunity Notice or elects to participate in a Rejected Lateral Opportunity will deliver a certificate executed by an executive or similar officer of such Partner to each other Partner certifying that: (i) such Lateral Opportunity or Rejected Lateral Opportunity is not, directly or indirectly, related in any way to any past, current or future-contemplated transaction involving the certifying Partner (including, to the extent covered by this Section 15.1, its applicable Affiliates) not described in the Lateral Opportunity Notice and (ii) taken as a whole and, in light of the circumstances in which the same were made, the Lateral Opportunity Notice does not and will not, to the best knowledge of the certifying Partner, as of the date when made, contain any untrue statement of a material fact or omit to state a material fact (other than omissions that pertain to matters of a general economic nature, matters generally known to each Partner, or matters of public knowledge that generally affect any of the industry segments included in the business of the Company) necessary in order to make the statements contained therein not misleading, and all financial projections contained in any Lateral Opportunity Notice have been prepared in good faith based upon assumptions believed by the Partner to be reasonable. Any breach of a representation or warranty contained in such certificate will be deemed to be a breach of a representation or warranty contained in this Agreement.

15.2 Project Financings. Each Partner will be responsible for arranging the financing of its share of Capital Contributions and advances or loans to or other investments in the Company (if project financing documents not completed); provided, however, that the Partners agree to use commercially reasonable, good faith efforts to review and pursue any project financing arrangement for the Company to the extent the terms and conditions of such project financing are in the best interest of each of the Partners.

15.3 Expansion Option.

(a) Any Partner (the “Exercising Partner”) will have the right to require the Company to construct, own and operate a particular Expansion Project (the “Expansion Option”) if:

(i) Any Person (including the Exercising Partner or its Affiliate) has delivered to the Partners a written notice requesting firm capacity or additional firm capacity (a “Capacity Request”) on TOPS to receive, store and deliver Oil under one or more existing or new Throughput Agreements (including Incremental Volumes, the Oil to be received, stored and delivered using such requested capacity is referred to as “Expansion Throughput”);

(ii) the Accessible Capacity is not sufficient practically to handle substantially all of the Expansion Throughput;

(iii) such Expansion Project is necessary to increase the Base Capacity to a level adequate to allow TOPS to handle the Expansion Throughput;

(iv) within 60 Days from the date of delivery of such Capacity Request (the “Expansion Option Period”) (A) the Partners held a meeting, a Unanimous Interest did not approve such Expansion Project and the Exercising Partner voted in favor of such Expansion Project at such meeting or (B) the Partners were unable to hold a meeting through no fault of the Exercising Partner; and

(v) the Expansion Option is exercised in accordance with the requirements of Section 15.3(b).

(b) Exercise. The Exercising Partner may exercise the Expansion Option only by delivering, at any time after such Expansion Project has been rejected or, if no vote was held with respect to such Expansion Project, after the Expansion Option Period, but in any case no later than 30 Days after the end of the Expansion Option Period, written notice of such exercise (the “Expansion Option Notice”) to the Company and each other Partner. Whenever an Exercising Partner delivers an Expansion Option Notice, every other Partner which voted in favor of the relevant Expansion Project at the last meeting during which such project was voted on (together with the Exercising Partner, the “Expansion Participants”) will have the right to participate, proportionately based on the relationship of its Partnership Interest to the Partnership Interests of all of the Expansion Participants, in such project on the same basis as the Exercising Partner, including the right to receive the Payout Amount out of 80% of the Expanded Capacity Revenues and the obligation to fund such project. Any Expansion Participant which desires to exercise its right to participate in such project must deliver to the other Partners a notice substantially similar to that delivered by the original Exercising Partner in accordance with the terms of this subsection, within 30 Days after it receives the Expansion Option Notice. Each Expansion Participant will provide to the other Expansion Participants and the Company an irrevocable commitment timely to fund the relevant Expansion Project and, if appropriate, assurances reasonably satisfactory to the Company and the other Expansion Participants that the relevant Expansion Participant has the ability to complete such Expansion Project. If any Expansion Participant pays any amount to the Company

in excess of the amount needed to complete the Expansion Project the Company will immediately return such excess amount to the Expansion Participant.

(c) Repayment. Until the Expansion Participants have (i) received payment of their share of the Expanded Capacity Revenues in an aggregate amount equal to the Payout Amount or (ii) the Company, by vote of a Unanimous Interest, has otherwise paid the unamortized portion of the Payout Amount to the Expansion Participants as described below, the Expansion Participants will be paid monthly amounts equal to 80% of the Expanded Capacity Revenues. Such amounts will be allocated among the Expansion Participants in the proportions that the Partnership Interest of each such Expansion Participant bears to the Partnership Interests of all such Expansion Participants. The remaining 20% of the Expanded Capacity Revenues will be retained by the Company and allocated to all of the Partners in accordance with Sections 5.1 and 5.2. After recovery of the Payout Amount or payment by the Company of the unamortized portion of the Payout Amount to the Expansion Participants as described below, all of the Expanded Capacity Revenues will be retained by the Company and allocated to all of the Partners based on their respective Partnership Interests. If, at any time, the Company, by vote of a Unanimous Interest, elects to prepay the unamortized amount of the Payout Amount, the Company will promptly pay an amount equal to the then remaining unpaid principal amount of the Payout Amount to the Expansion Participants, which remaining unpaid principal amount will be calculated by treating as principal payments two-thirds (2/3rds) of all amounts received by the Expansion Participants prior to such time in satisfaction of the Payout Amount.

(d) Capacity. Prior to proceeding with any Expansion Project in accordance with this Section, all of the Partners will cooperate to establish (i) the Accessible Capacity and (ii) an expansion design to handle the Expansion Throughput. If the Partners cannot agree on any such matter, the Company will engage an independent engineering consultant (of national prominence with experience in the relevant geographical area) to resolve each such matter.

(e) Treatment as Loan. Any amount paid by one or more Partners pursuant to Section 15.3 will be considered to be a limited recourse, partially secured loan from such Partner to the Company, with such loan payable only from, and secured only by a security interest granted by the Company in, 80% of the Expanded Capacity Revenues until such Payout Amount is paid in full. Except for such security interest in 80% of the Expanded Capacity Revenues, such loan will be without recourse against the Company. The Company will have no obligation to repay such loan except to the extent that 80% of the Expanded Capacity Revenues are available.

15.4 Termination of Throughput Agreement. Any Partner or Partners may propose that the Company exercise its right according to the terms of a Throughput Agreement to terminate such Throughput Agreement by delivering written notice to the Company and each of the other Partners. If a Required Interest does not approve the termination of the Throughput Agreement and the Company does not terminate the Throughput Agreement by the deadline set forth in such Throughput Agreement for termination thereof, such Partner or Partners shall have the right to dissociate from the Company provided such Partner forfeit its investment in the

Company and its right to any buy-out of its interest in the Company and such dissociation shall not be in breach of this Agreement. Such dissociating Partner shall not be obligated to the Company or the other Partners for any further obligations under this Agreement.

16.17 Remedies. Except as expressly provided herein (including in Section 12.1), the rights, obligations and remedies created by this Agreement are cumulative and in addition to any other rights, obligations or remedies otherwise available at law or in equity. In lieu of seeking judicial remedies, nothing herein will be considered an election of remedies. In addition, any successful Partner is entitled to recover from any other Partner(s) against whom any claim or dispute is successfully brought its reasonable costs related to enforcing this Agreement, including reasonable attorneys’ and experts’ fees, and arbitration expenses. NOTWITHSTANDING ANYTHING TO THE CONTRARY, THE PARTIES WAIVE ANY AND ALL RIGHTS, CLAIMS OR CAUSES OF ACTION ARISING UNDER THIS AGREEMENT FOR INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES. A PARTY MAY RECOVER FROM THE OTHER PARTY ALL COSTS, EXPENSES OR DAMAGES INCLUDING INDIRECT, SPECIAL, CONSEQUENTIAL, INCIDENTAL, EXEMPLARY, PUNITIVE AND DAMAGES PAID OR OWED TO ANY THIRD PARTY FOR WHICH SUCH PARTY HAS A RIGHT TO RECOVER FROM THE OTHER PARTY.

16.18 Grant of Security Interest. Each Party grants to the Company a Security Interest in all of such Party’s Partnership Interest and other rights hereunder (including such Party’s rights to distributions) to secure the payment and performance of such Party’s obligations under Section 3.4 and Article IV. Each Party grants to the other Partners a Security Interest in all of such Party’s Partnership Interest and other rights hereunder (including such Party’s rights to distributions) to secure the payment and performance of such Party’s obligations to a Lending

Partner under Section 4.3. The Security Interests granted pursuant to this Agreement are subordinate to any lenders to a Party of a loan for the purposes of financing a Capital Contribution as may be required by such lenders but otherwise are prior to all other Security Interests on such collateral (except that they are pari passu as among the Company and applicable Partners). The Company and any Partner acting on behalf of the Company will have the right, in addition to the other rights and remedies granted to it pursuant to this Agreement or available to it at Law or in equity, to take any action (including court proceedings and exercising the rights of a secured party under the Uniform Commercial Code of any applicable State) that a Required Interest or such Partner may deem appropriate to obtain payment and/or performance from such Party of any such obligation. The failure of such Party to pay or perform any of its obligations secured hereunder shall constitute a default under the Uniform Commercial Code of any applicable state and the Company and any Partner (on behalf of the Company) shall have all rights provided to a secured party thereunder. Such Party hereby waives all demands and notices to the maximum extent permitted by the Uniform Commercial Code of any applicable state and any other law. At any time and from time to time, upon the written request of the Company or any Partner, and at the sole expense of such Party, any Party will promptly and duly execute and deliver such further instruments and documents and take such further action as the Company or the applicable Partner may reasonably request for the purpose of obtaining or preserving the full benefits of the Security Interests granted hereunder and of the rights and powers herein granted, including the filing of any financing or continuation statements under the Uniform Commercial Code in effect in any jurisdiction with respect to the Security Interests created hereby. Each Party hereby authorizes the Company, any other Partner or either of their respective counsel or representative, at any time and from time to time, to file financing statements and amendments to financing statements that describe the collateral covered by such financing statements in such jurisdictions as the Company or other Partner may deem necessary or desirable in order to perfect the Security Interests granted hereby. Each Party hereby further authorizes the Company, any other Partner or either of their respective counsel or representative, at any time and from time to time, to file continuation statements with respect to previously filed financing statements. A photographic or other reproduction of this Agreement will be sufficient as a financing statement for filing in any jurisdiction. In the event the Company exercises its remedies hereunder, and as a result of which the Company acquires any Partnership Interest of a Party, such Partnership Interest shall be treated as redeemed for purposes of determining the relative Partnership Interest of the remaining Partners and such Party shall have no further rights under this Agreement with respect to such Partnership Interest.

16.19 Default Budgets. To the extent that the applicable Required Interest does not approve an operating or capital expenditure Budget for a relevant period, the Company shall operate using the applicable Budget for the prior such period, adjusted (without duplication) to reflect increases or decreases resulting from the following events, and which shall govern until such time as the Required Interest approves a new proposed budget, but no later than one year:

(a) the operation of escalation or de-escalation provisions in contracts in effect at such time as a result of the passage of time or the occurrence of events beyond the control of the Company to the extent such contracts are still in effect;

(b) elections made in any prior period under contracts contemplated by the Budget for the prior period regardless of which party to such contracts makes such election;

(c) increases or decreases in expenses attributable to the effect of employee or contractor additions or reductions during the prior period contemplated by the Budget for the prior period;

(d) changes in interest expense attributable to any indebtedness of the Company;

(e) increases in overhead expenses in an amount equal to (i) the total of overhead expenses reflected in the Budget for the prior period multiplied by (ii) the increase in the Consumer Price Index for All Urban Consumers (CPI-U) Houston-Galveston-Brazoria, Texas area over the prior period;

(f) the reasonably anticipated incidence of costs during such period for any legal, accounting and other professional fees or disbursements in connection with events or changes not contemplated at the time of preparation of the Budget for the prior period;

(g) decreases in expenses attributable to non-recurring items reflected in the prior period’s Budget; and

INTRODUCTION

1. Contemporaneously herewith, Oiltanking, TEPPCO and Enterprise Offshore Port System, LLC, a Texas limited liability company (“Obligor”), are entering into that certain Partnership Agreement of TOPS, dated the same date as this Agreement (including the exhibits, annexes and schedules thereto, and as amended, restated, supplemented and otherwise modified from time to time, the “Partnership Agreement”).

2. Obligor is a wholly-owned indirect subsidiary of the Guarantor.

3. It is the intention of the Parties that TOPS will be direct beneficiary of this Agreement.

4. The Guarantor acknowledges that it will indirectly benefit from Obligor being party to the Partnership Agreement.

5. Oiltanking, TEPPCO and TOPS desire that the Guarantor guarantee Obligor’s performance under Section 4.1 of the Partnership Agreement (the “Guaranteed Provision”) upon the terms and conditions set forth herein.

AGREEMENT

For and in consideration of the premises and mutual covenants herein contained and other good and valuable consideration (the receipt and sufficiency of which is hereby acknowledged), the Parties do hereby stipulate and agree as follows:

1. Defined Terms. Capitalized terms used herein but not defined will have the meaning given them in the Partnership Agreement.

2. The Guaranty.

(a) Subject to Section 2(b), Section 2(c) and Section 2(d), the Guarantor hereby irrevocably and unconditionally guarantees to TOPS the full and timely performance and discharge (including the payment of money) by Obligor of all obligations and liabilities of Obligor now existing or hereafter arising under the Guaranteed Provision (the “Guaranteed Obligations”) and in each case hereby agrees that if Obligor fails (i) to pay any undisputed amount when and as the same becomes due and payable by Obligor to TOPS under the Guaranteed Provision, or (ii) to perform and

Exhibit C to Partnership Agreement - Page 2

discharge in full, on a timely basis, any of its respective obligations or liabilities in accordance with the Guaranteed Provision, the Guarantor will, upon effectiveness of notice of such failure from TOPS or any Partner, forthwith perform and discharge any such obligation or liability to TOPS (including the payment of money) as such performance and discharge is required to be made or done by Obligor pursuant to the terms of the Guaranteed Provision. Subject to Section 2(b), Section 2(c) and Section 2(d), the guaranty in the preceding sentence is an absolute, present and continuing guaranty of performance of obligations (including the payment of money) and not of collectability and is in no way conditional or contingent upon any attempt to collect from Obligor or upon any other action, occurrence or circumstance whatsoever. Subject to Section 2(b), Section 2(c) and Section 2(d), including the appropriate resolution of any applicable “Capital Call Disputes” as provided under Section 4.1(f) of the Partnership Agreement, it will not be necessary for TOPS or any Partner, in order to enforce such performance by the Guarantor, first to institute suit or exhaust its remedies against Obligor, any other guarantor, or any other Person liable with respect to the Guaranteed Obligations.

(b) Notwithstanding anything to the contrary contained in this Section 2 or elsewhere in this Agreement, Oiltanking, TEPPCO and TOPS each separately acknowledge and agree that the Guarantor will have the benefit of and the right to assert any defenses against the claims of TOPS which are available to Obligor and which would have also been available to the Guarantor if the Guarantor had been in the same contractual position as Obligor under the Partnership Agreement, including the appropriate resolution of any applicable “Capital Call Dispute” as provided under Section 4.1(f) of the Partnership Agreement, other than defenses arising from the bankruptcy or insolvency of Obligor.

(c) This guaranty is limited in amount. Notwithstanding anything to the contrary contained in this Section 2 or elsewhere in this Agreement, Oiltanking, TEPPCO and TOPS each separately acknowledge and agree that the Guarantor’s obligations under this Agreement, inclusive of all attorneys’ fees, expenses and other sums due hereunder, shall not exceed the aggregate sum of US $700 million.

(d) Notwithstanding anything to the contrary contained in this Section 2 or elsewhere in this Agreement, Oiltanking, TEPPCO and TOPS each separately acknowledge and agree that the Guarantor’s obligations under this Agreement shall terminate and be of no further force or effect upon the payment of 100% of all amounts for costs and expenses incurred on behalf of TOPS related to the formation of TOPS and of all amounts to be incurred by TOPS to design, construct, install and place in service the Initial Facilities as necessary to timely and satisfactorily fulfill all of TOPS’s obligations under the Throughput Agreements.

3. Obligations Absolute. Subject to Section 2(b), Section 2(c) and Section 2(d), the obligations of the Guarantor hereunder will be absolute, continuing and unconditional and will not be released, discharged or in any way affected, by any of the following:

Exhibit C to Partnership Agreement - Page 3

(a) any amendment, modification of or supplement to the Partnership Agreement or any other instrument referred to therein or any assignment or transfer of any rights or obligations thereunder;

(b) any extension of the time for the payment of all or any portion of any sums payable under the Guaranteed Provision or the extension of time for the performance of any obligations under the Guaranteed Provision;

(c) any failure, omission, delay or lack of diligence on the part of TOPS to enforce, assert or exercise, or any waiver of, any right, privilege, power or remedy conferred on TOPS by the Guaranteed Provision, or any action on the part of TOPS granting indulgence or extension of any kind;

(d) any bankruptcy, insolvency, readjustment, composition, liquidation, dissolution or similar proceeding or any other defense that may arise in connection with any such proceeding with respect to Obligor, the Guarantor or any other Person;

(e) any change in the corporate or partnership structure, existence or ownership of the Guarantor, Obligor or TOPS (including the termination or liquidation of any such Person) or any sale, lease or transfer of any or all of the assets of the Guarantor, Obligor or TOPS to any Person;

(f) any failure on the part of Obligor for any reason to comply with or perform any of the terms of any other agreement with the Guarantor; or

(g) any applicable Law hereafter in effect in any jurisdiction affecting any of the rights under or terms of the Guaranteed Provision except to the extent any such Law renders Guarantor’s actions hereunder either unenforceable or illegal.

4. Waiver. The Guarantor unconditionally waives, to the fullest extent permitted by applicable Law: (a) except as required under Sections 1.1 (under the definition of “Default”), 4.1(c) and 4.1(d) of the Partnership Agreement (which notices TOPS expressly agrees to deliver to Guarantor pursuant to Section 7 hereof), notice of acceptance hereof, of any action taken or omitted in reliance hereon, of demand, and of any defaults by Obligor in the payment or performance of any Guaranteed Obligations, and of any of the matters referred to in Section 3 hereof; (b) all notices that may otherwise be required by applicable Law or otherwise to preserve any of the rights of TOPS against the Guarantor, including presentment to or demand for payment from Obligor or the Guarantor, notice to Obligor of claims with a court in the event of the bankruptcy of Obligor; and (c) any requirement of diligence on the part of TOPS.

5. Reinstatement of Guaranty. This Agreement will continue to be effective, or be reinstated, as the case may be, if and to the extent at any time any payment, in whole or in part, made by Obligor or the Guarantor to TOPS in respect of the Guaranteed Obligations is rescinded or must otherwise be restored or returned by TOPS upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Obligor, or upon or as a result of the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to Obligor or any substantial part of its property, or otherwise, all as though such payments had not been made and, to the extent permitted by applicable law, in such event the Guarantor will pay TOPS an amount equal

Exhibit C to Partnership Agreement - Page 4

to the payment that has been rescinded or returned. TOPS will not be required to litigate or otherwise dispute its obligation to make such repayments if it in good faith believes that such obligation exists.

6. Representations, Covenants and Warranties of Guarantor. The Guarantor represents, covenants and warrants as follows as of the date hereof:

(b) Approval and Enforceability of Agreement. The execution, delivery and performance of this Agreement have been duly authorized by all necessary action on the part of the Guarantor.

RE: Texas Offshore Port System

Gentlemen:

On this day, Oiltanking Freeport, L.P. (“Oiltanking”), TEPPCO O/S Port System, LLC (“TEPPCO”), and Enterprise Offshore Port System, LLC (“Enterprise”) executed the Partnership Agreement of Texas Offshore Port System (the “Partnership Agreement”). All terms capitalized herein and not otherwise defined herein shall have the meanings ascribed to them in the Partnership Agreement.

Pursuant to Section 4.6 of the Partnership Agreement, at the time of its execution each Partner was required to cause its respective Affiliate Guarantor to issue a guaranty of such Partner’s obligation to contribute Capital Contributions. Each of the Partners has caused its Affiliate to execute and deliver an appropriate guaranty, save and except that Oiltanking did not deliver the Specific and Limited Guaranty Agreement from its parent, Oiltanking GmbH. Oiltanking has advised the TOPS Partnership, Enterprise and TEPPCO that it requires additional time to deliver the Oiltanking GmbH guaranty because the delivery of such guaranty requires (i) the approval of Oiltanking GmbH’s Supervisory Board and (ii) the approval of Oiltanking GmbH’s bankers. Oiltanking anticipates that its parent, Oiltanking GmbH, will be able to deliver the Oiltanking GmbH guaranty on or before September 30, 2008.

By this letter agreement, TEPPCO, Enterprise, the TOPS Partnership and Oiltanking hereby agree that:

1. Oiltanking shall use its best efforts to cause the Oiltanking GmbH guaranty in the form attached hereto as Exhibit A to be delivered to the TOPS Partnership on or before September 30, 2008 (hereinafter [as same may be extended] the “Deadline”);

2. Oiltanking shall not be considered to be in breach of the Partnership Agreement due to its inability to deliver the Oiltanking GmbH guaranty prior to the Deadline; and

3. In the event that Oiltanking fails to deliver the Oiltanking GmbH guaranty to the TOPS Partnership on or before the Deadline, then Enterprise and TEPPCO may either, at their respective sole option and in their respective sole discretion, (i) extend the Deadline during which period Oiltanking shall continue to use its best efforts to diligently pursue delivery of the Oiltanking GmbH guaranty or (ii) as their sole and exclusive remedy, and notwithstanding anything to the contrary in the Partnership Agreement, require Oiltanking to withdraw from the

Exhibit C to Partnership Agreement - Page 24

Partnership, at which time the TOPS Partnership shall refund all of Oiltanking’s Capital Contributions. Following the refund of such Capital Contributions, Oiltanking’s partnership interest shall be deemed to be redeemed and the remaining Partners and the TOPS Partnership shall thereafter have no rights, duties or obligations to Oiltanking under the Partnership Agreement, and Oiltanking shall thereafter have no rights, duties or obligations to the remaining Partners or to the TOPS Partnership under the Partnership Agreement. Oiltanking hereby waives and releases (and shall cause its Affiliate Oiltanking Houston L.P. to waive and release) all rights that it and its affiliates may have against the remaining Partners and their affiliates under the Term Sheet for Texas Offshore Oil Port Project dated April 16, 2007, executed in anticipation of the Partnership Agreement.

If this letter correctly sets forth the terms of our agreement, please so indicate by signing the attached copy and returning it to Oiltanking.

Very truly yours,

Enterprise, TEPPCO and Oiltanking Plan

Texas Offshore Crude Oil Port and Pipeline System

Houston, Texas (August 18, 2008) – Enterprise Products Partners L.P. (NYSE: EPD), TEPPCO Partners, L.P. (NYSE: TPP) and Oiltanking Holding Americas, Inc. today announced they have formed a joint venture to design, construct, own and operate a new Texas offshore crude oil port and pipeline system to facilitate delivery of waterborne crude oil to refining centers along the upper Texas Gulf Coast. The initiative will provide an efficient alternative to offshore lightering and inland dock operations.

The Texas Offshore Port System (“TOPS”) project would include an offshore port, two onshore storage facilities with approximately 5.1 million barrels of total crude oil storage capacity, and an associated 160-mile pipeline system with the capacity to deliver up to 1.8 million barrels per day (BPD) of crude oil. System capacity could be expanded with construction of additional offshore facilities. Development of the offshore port system and onshore infrastructure is supported by long-term contracts with Motiva Enterprises LLC and an affiliate of Exxon Mobil Corporation, which together have committed a total volume of approximately 725,000 BPD.

Demand for TOPS is being driven by planned and expected refinery expansions along the upper Texas Gulf Coast that are anticipated to add approximately 425,000 BPD of capacity beginning in 2010, as well as expected increases in general ship traffic at onshore ports. According to data from the federal Energy Information Administration, the Texas Gulf Coast is home to refineries with aggregate crude oil capacity of 3.9 million BPD (including planned and announced expansions), 2.5 million BPD of which are imported on vessels that require lightering services. Given the forecasted increased shipping traffic resulting from incoming crude oil supplies and operating limitations of ship channels, TOPS would offer refiners another delivery option that would provide added flexibility and enhanced reliability. TOPS is designed to allow operations 24 hours

per day without restrictions on movements and vessel size that limit most ship channels. TOPS would be able to accommodate the largest vessels which can carry approximately 3 million barrels of crude oil. The location of TOPS is also designed to avoid delays and risks related to fog, navigation hazards and channel closures on coastal waterways. Over the next several years, key port locations along the Texas Gulf Coast are expected to see a sharp increase in total traffic for all types of cargo, and TOPS would be well-positioned to play an important role in relieving potential congestion.

“With refining capacity along the upper Texas coast continuing to expand, TOPS offers a comprehensive solution for ensuring reliable access to supplies of crude oil,” said Michael A. Creel, president and chief executive officer of Enterprise. “This project should provide refiners with cost savings, operating efficiencies and access to additional supplies beyond the Gulf Coast region. We are very pleased to be working with our joint venture partners, each of which brings complementary assets and expertise in the crude oil logistics business. In addition, TOPS should provide Enterprise with a new source of fee-based cash flow for decades to come.”

Jerry E. Thompson, president and chief executive officer of the general partner of TEPPCO said, “The deepwater port is an integral part of our strategic plan for growing the partnership, which includes pursuing attractive infrastructure projects that provide facilities to meet the growing demand for imported crude oil coming into the Gulf Coast refining centers. We are very pleased to be part of this project, which should not only offer significant benefits for TEPPCO and our investors, but will also better serve the refining industry and support its efforts to meet the future energy needs of consumers.”

Carlin G. Conner, chairman of the new joint venture’s Management Committee and president and chief executive officer of Oiltanking’s North American subsidiaries, said, “TOPS is a key U.S. Gulf Coast infrastructure project that would enhance delivery of crude oil to the western gulf coast refiners. We are pleased to be a partner in TOPS. Each of the partners brings experience and know-how to this project, which is a necessary development to further drive Gulf Coast refining efficiencies. The project would also provide our customers with access to an efficient and reliable crude oil delivery system for years to come.” Conner added, “Our investment in TOPS

complements our other Gulf Coast terminals and is another step toward our goal of becoming the premier crude oil and chemical feedstock terminal company in North America.”

The TOPS project involves construction of a deepwater port located approximately 36 miles offshore from Freeport, Texas, and an onshore distribution and storage system. As designed, the deepwater port will feature two single-point mooring buoys that will essentially serve as floating docks for the vessels. Located in about 115 feet of water, the buoys will be able to offload crude oil at rates up to 100,000 barrels per hour. A subsea pipeline will connect the buoys to the onshore distribution system near Freeport. Utilizing directional drilling techniques to minimize beach impact, the TOPS pipeline system would run from the offshore port shore crossing to Freeport and extend along the Texas Gulf Coast to Texas City, Texas, connecting to a 3.9 million barrel crude oil storage facility. From there, the pipeline would connect to existing crude oil pipeline systems currently serving the Texas City and Houston Ship Channel refineries.

A separate but complementary component of TOPS would involve construction of a 75-mile pipeline extending from Texas City to its terminus at a planned storage facility with 1.2 million barrels of crude oil capacity near Port Arthur, Texas. The storage tanks are designed to connect to various refineries and other facilities via pipelines. This pipeline system would have the added capability of delivering waterborne and offshore crude oil from existing Texas City docks and storage facilities to all Port Arthur/Beaumont area refineries.

Affiliates of Enterprise, TEPPCO and Oiltanking each have a one-third ownership in the new joint venture and expect to invest approximately $600 million each in the initiative, which, subject to obtaining certain regulatory approvals and permits, is scheduled to begin service in the fourth quarter of 2010.

An investor conference call to discuss the TOPS project will be held on August 18, 2008, at 9 a.m. CDT. Interested parties may listen live over the Internet and view the accompanying slides by accessing the Enterprise web site (www.epplp.com) under “Investor Relations” or TEPPCO’s website (www.teppco.com) under “Investors”. Listeners are encouraged to access the website of their choice at least five to 10 minutes

prior to the scheduled start time of the call. An audio replay will be available for seven days after the call.
