GULFTERRA ENERGY PARTNERS, L.P. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 1. BASIS OF PRESENTATION In May 2003, we changed our name to GulfTerra Energy Partners, L.P. from El Paso Energy Partners, L.P. and reorganized our general partner. Our one percent general partner interest is now owned by GulfTerra Energy Company, L.L.C. replacing El Paso Energy Partners Company as the general partner. In connection with our name change, we have also changed the names of several subsidiaries as listed in the table below.

NEW NAME FORMER NAME - -------- ---------------------------------- GulfTerra Energy Finance Corporation............... El Paso Energy Finance Corporation GulfTerra Arizona Gas, L.L.C. ..................... El Paso Arizona Gas, L.L.C. GulfTerra Intrastate, L.P. ........................ El Paso Energy Intrastate, L.P. GulfTerra Texas Pipeline, L.P. .................... EPGT Texas Pipeline, L.P. GulfTerra Holding V, L.P. ......................... EPN Holding Company, L.P.
We prepared this Quarterly Report on Form 10-Q under the rules and regulations of the United States Securities and Exchange Commission (SEC). Because this is an interim period filing presented using a condensed format, it does not include all of the disclosures required by generally accepted accounting principles. You should read it along with our 2002 Annual Report on Form 10-K, which includes a summary of our significant accounting policies and other disclosures. The financial statements as of March 31, 2003, and for the quarters ended March 31, 2003 and 2002, are unaudited. We derived the balance sheet as of December 31, 2002, from the audited balance sheet filed in our 2002 Annual Report on Form 10-K. In our opinion, we have made all adjustments, all of which are of a normal, recurring nature, to fairly present our interim period results. Due to the seasonal nature of some of our businesses, information for interim periods may not depict the results of operations for the entire year. In addition, prior period information presented in these financial statements includes reclassifications which were made to conform to the current period presentation. These reclassifications have no effect on our previously reported net income or partners' capital. We have also reflected the results of operations from our Prince assets disposition as discontinued operations in the quarter ended March 31, 2002. Our accounting policies are consistent with those discussed in our 2002 Annual Report on Form 10-K, except as discussed below. Accounting for Asset Retirement Obligations On January 1, 2003, we adopted Statement of Financial Accounting Standards (SFAS) No. 143, Accounting for Asset Retirement Obligations. The provisions of this statement relate primarily to our obligations to plug abandoned offshore wells in our Garden Banks Blocks 72 and 117, Viosca Knoll Block 817, and West Delta Block 35. We recorded a $1.7 million increase to income as a cumulative effect of accounting change upon our adoption of SFAS No. 143. We also reversed $7.1 million negative salvage value and recorded non-current retirement assets totaling $3.1 million with useful lives ranging from 11 to 19 years to property, plant and equipment, accumulated depreciation of $2.8 million, and retirement obligations totaling $5.7 million to noncurrent liabilities. - --------------- As generally used in the energy industry and in this document, the following terms have the following meanings: /d = per day Mcf = thousand cubic feet Bbl = barrel MDth = thousand dekatherms MBbls = thousand barrels MMcf = million cubic feet Bcf = billion cubic feet MMBbls = million barrels When we refer to cubic feet measurements, all measurements are at 14.73 pounds per square inch.
5

Other than our obligations to plug and abandon wells, we cannot estimate the costs to retire or remove assets used in our business because we believe the assets do not have definite lives or we do not have the legal obligation to abandon or dismantle the assets. Also, we believe that the life or underlying reserves cannot be estimated. Therefore, we have not recorded any liabilities relating to our assets, other than the liability associated with the plug and abandonment of offshore wells. The pro forma amount of our asset retirement obligations for the quarters ending March 31, 2002 and 2003 and for the year ending December 31, 2002, assuming asset retirement obligations as provided for in SFAS No. 143 were recorded prior to the earliest period presented are shown below:

LIABILITY BALANCE LIABILITY BALANCE AS OF AS OF ------------------------ YEAR JANUARY 1 ACCRETION MARCH 31 DECEMBER 31 - ---- --------- --------- --------- ------------ (IN THOUSANDS) 2002........................................ $5,277 $112 $5,389 $5,726 2003........................................ 5,726 122 5,847 N/A
Reporting Gains and Losses from the Early Extinguishment of Debt In January 2003, we adopted SFAS No. 145, Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections. Accordingly, we now evaluate the nature of any debt extinguishments to determine whether to report any gain or loss resulting from the early extinguishment of debt as an extraordinary item or as income from continuing operations. Accounting for Costs Associated with Exit or Disposal Activities In January 2003, we adopted SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. This statement will impact any exit or disposal activities that we initiate after January 1, 2003 and we will now recognize costs associated with exit or disposal activities when they are incurred rather than when we commit to an exit or disposal plan. Our adoption of this pronouncement did not have an effect on our financial position or results of operations for the quarter ended March 31, 2003. Accounting for Guarantees In accordance with the provisions of Financial Accounting Standards Board (FASB) Interpretation (FIN) No. 45, Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, we record a liability at fair value for all guarantees issued after December 31, 2002, including financial, performance, and fair value guarantees. Our initial application of this standard for the quarter ended March 31, 2003 did not have an effect on our financial position or results of operations. We have provided disclosures relating to our guarantee activities in Note 6. Consolidation of Variable Interest Entities In January 2003, the FASB issued FIN No. 46, Consolidation of Variable Interest Entities. This interpretation defines a variable interest entity (VIE) as a legal entity whose equity owners do not have sufficient equity at risk and/or a controlling financial interest in the entity. This standard requires that companies consolidate a VIE if it is allocated a majority of the entity's losses and/or returns, including fees paid by the entity. We have not created nor have we obtained an interest in any VIEs since January 31, 2003, and therefore, our adoption of the initial provisions of this standard did not have an effect on our financial position or results of operations. Further, we have completed an assessment of our interests existing prior to February 1, 2003, and have determined that our adoption of the additional provisions of this standard will not have an effect on our financial position or results of operation. 6

Accounting for Stock-Based Compensation We use the intrinsic value method established in Accounting Principles Board Opinion (APB) No. 25, Accounting for Stock Issued to Employees, to value unit options issued to former employees of our general partner and our board of directors under our Omnibus Plan and Director Plan. For the quarters ending March 31, 2003 and 2002, the cost of this stock-based compensation had no impact on our net income, as all options granted had an exercise price equal to the market value of the underlying common stock on the date of grant. In December 2002, the FASB issued SFAS No. 148, Accounting for Stock-Based Compensation Transition and Disclosure. This statement amends SFAS No. 123, to provide alternative methods of transition for a voluntary change to the fair value method of accounting for stock-based employee compensation. In addition, this statement amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements about the methods of accounting for stock-based employee compensation and the effect of the method used on reported results. This statement is effective for the fiscal years ending after December 15, 2002. We have decided that we will continue to use APB No. 25 to value our stock-based compensation and will include data providing the pro forma income impacts of using the fair value method as required by SFAS No. 148. If compensation expense related to these plans had been determined by applying the fair value method in SFAS No. 123, Accounting for Stock-Based Compensation, our net income allocated to common unitholders and net income per common unit would have approximated the pro forma amounts below:

QUARTER ENDED MARCH 31, ---------------- 2003 2002 ------- ------ (IN THOUSANDS) Net income allocated to common unitholders, as reported..... $18,794 $6,839 Add: Stock-based employee compensation expense included in reported net income....................................... 313 270 Less: Stock-based employee compensation expense determined under fair value based method............................. (191) (573) ------- ------ Pro forma net income allocated to common unitholders........ $18,916 $6,536 ======= ====== Earnings per common unit, as reported....................... $ 0.43 $ 0.17 ======= ====== Earnings per common unit, pro forma......................... $ 0.43 $ 0.16 ======= ======
The effects of applying SFAS No. 123 in this pro forma disclosure are not indicative of future amounts. 2. ACQUISITION During the first quarter of 2003, we recorded additional purchase price adjustments of approximately $4.7 million on our April 2002 EPN Holding asset acquisition related to natural gas imbalances. The following table summarizes our revised allocation of the fair values of the assets acquired and liabilities assumed at 7

April 8, 2002. Our allocation among the assets acquired is based on the results of an independent third-party appraisal.

AT APRIL 8, 2002 -------------- (IN THOUSANDS) Current assets.............................................. $ 2,217 Property, plant and equipment............................... 780,648 Intangible assets........................................... 3,500 -------- Total assets acquired..................................... 786,365 -------- Current liabilities......................................... 27,842 Environmental liabilities................................... 21,136 -------- Total liabilities assumed................................. 48,978 -------- Net assets acquired.................................... $737,387 ========
3. PARTNERS' CAPITAL Cash distributions In February 2003, we paid cash distributions of $0.675 per common and Series C unit for an aggregate of $37.1 million and our general partner received incentive distributions of $14.6 million. In April 2003 we declared a cash distribution of $0.675 per common unit for the quarter ended March 31, 2003, which we will pay on May 15, 2003, to holders of record as of April 30, 2003. Also in May 2003, we will pay our general partner $15.5 million in incentive distributions. At the current distribution rates, our general partner receives approximately 29 percent of the total cash distributions we pay. Public offering of common units In April 2003, we issued 3,450,000 common units at the public offering price of $31.35 per unit. We used the net cash proceeds of approximately $103 million to temporarily reduce indebtedness outstanding under our $600 million revolving credit facility and pay fees and expenses associated with this offering. In addition, our general partner contributed approximately $1 million of our Series B preference units to us in April 2003 in order to maintain its one percent general partner interest. Other We have reflected the issuance of our restricted units to non-employee directors of our Board of Directors under the 1998 Unit Option Plan for Non-Employee Directors as deferred compensation and as an increase in common units. This deferred compensation was allocated 1% to our general partner and 99% to our limited partners and is being amortized over the vesting period of the restricted units. The unamortized amount of our total deferred compensation as of March 31, 2003, was approximately $0.9 million. 8

4. PROPERTY, PLANT AND EQUIPMENT Our property, plant and equipment consisted of the following:

MARCH 31, DECEMBER 31, 2003 2002 ---------- ------------ (IN THOUSANDS) Property, plant and equipment, at cost Pipelines................................................. $2,318,860 $2,317,503 Platforms and facilities.................................. 128,582 128,582 Processing plant.......................................... 300,897 300,897 Oil and natural gas properties............................ 131,099 127,975 Storage facilities........................................ 330,639 331,562 Construction work-in-progress............................. 259,270 177,964 ---------- ---------- 3,469,347 3,384,483 Less accumulated depreciation, depletion and amortization... 678,587 659,545 ---------- ---------- Property, plant and equipment, net..................... $2,790,760 $2,724,938 ========== ==========
5. FINANCING TRANSACTIONS CREDIT FACILITIES Our credit facility consists of two parts: a $600 million revolving credit facility maturing in 2004 and a $160 million senior secured term loan maturing in 2007. Our credit facility and the GulfTerra Holding V, L.P. (GulfTerra Holding, formerly known as EPN Holding) term credit facility are guaranteed by us and all of our subsidiaries, except for our unrestricted subsidiaries (Matagorda Island Area Gathering System, Arizona Gas Storage, L.L.C. and GulfTerra Arizona Gas, L.L.C., formerly known as EPN Arizona Gas, L.L.C.), and by GulfTerra Energy Finance Corporation (formerly known as El Paso Energy Partners Finance Corporation) and our general partner, and are collateralized with substantially all of our assets (excluding our unrestricted subsidiaries) and our general partner's general and administrative services agreement. The interest rates we are charged on each of these credit facilities are determined using one of two indices that include (i) a variable base rate (equal to the greater of the prime rate as determined by JP Morgan Chase Bank, the federal funds rate plus 0.5% or the Certificate of Deposit (CD) rate as determined by JP Morgan Chase Bank increased by 1.00%); or (ii) LIBOR. Our revolving credit facility, senior secured term loan and the GulfTerra Holding term credit facility contain covenants that include restrictions on our subsidiaries' ability to incur additional indebtedness or liens, sell assets, make loans or investments, acquire or be acquired by other companies and amend some of our contracts, as well as requiring maintenance of certain financial ratios. Failure to comply with the provisions of any of these covenants could result in acceleration of our debt and other financial obligations and that of our subsidiaries and restrict our ability to make distributions to our unitholders. Revolving Credit Facility As of March 31, 2003, we had $471 million outstanding on our revolving credit facility at an average interest rate of 3.15%. The total amount available to us at March 31, 2003 under this facility is $80 million. The amounts outstanding under our revolving credit facility bear interest at our option at either (i) 0.75% over the variable base rate described above; or (ii) 1.75% over LIBOR. Senior Secured Term Loan As of March 31, 2003, we had $160 million outstanding under our senior secured term loan with an average interest rate of 5.22%. The amounts outstanding under our senior secured term loan bear interest at our option at either (i) 2.25% over the variable base rate described above; or (ii) 3.50% over LIBOR. 9

GulfTerra Holding Term Credit Facility As of March 31, 2003, the outstanding balance under the GulfTerra Holding term credit facility was $160 million with an average interest rate of 3.57%. The balance outstanding under the GulfTerra Holding term credit facility bears interest at our option at either (i) 1.00% over the variable base rate described above; or (ii) 2.25% over LIBOR. Senior Secured Acquisition Term Loan As part of our November 2002 San Juan assets acquisition, we entered into a $237.5 million senior secured acquisition term loan to fund a portion of the purchase price. We repaid the senior secured acquisition term loan in March 2003 with proceeds from our issuance of $300 million 8 1/2% senior subordinated notes due 2010. We recognized a loss of $3.8 million related to the write-off of unamortized debt issuance costs. From the issuance of the senior secured acquisition term loan in November 2002 to its repayment date, the interest rates on our revolving credit facility and GulfTerra Holding term credit facility were 2.25% over the variable base rate described above or LIBOR increased by 3.50%. SENIOR SUBORDINATED NOTES Each issue of our senior subordinated notes is subordinated in right of payment to all existing and future senior debt including our existing credit facilities. Additionally, our senior subordinated notes include provisions that, among other things, restrict our subsidiaries' ability to acquire assets, incur additional indebtedness or liens, sell assets, acquire or be acquired by other companies, and enter into sale and lease back transactions unless we meet the financial ratios and other specific conditions provided in these covenants. These restrictive covenants will be suspended should our notes be rated Baa3 or higher by Moody's or BBB- or higher by S&P. In March 2003, we issued $300 million in aggregate principal amount of 8 1/2% senior subordinated notes. These notes bear interest of 8 1/2% per year, payable semi-annually in June and December, and mature in June 2010. We used the proceeds of approximately $293 million, net of issuance costs, to repay $237.5 million of indebtedness under our senior secured acquisition term loan and to temporarily repay $56.5 million of the balance outstanding under our revolving credit facility. These notes are subject to a registration rights agreement under which we are required to file an exchange offer registration statement on Form S-4 with the SEC on or prior to July 8, 2003. The registration statement on Form S-4 must then become effective on or prior to September 1, 2003 or we will be subject to penalties of approximately $15,000 per week until a registration statement is filed with the SEC and declared effective. We may, at our option, prior to June 1, 2006, redeem up to 33 percent of the originally issued aggregate principal amount of these notes at a redemption price of 108.50 percent of the principal amount. On or after June 1, 2007, we may redeem all or part of these notes at 104.25 percent of the principal amount. OTHER CREDIT FACILITIES Poseidon Oil Pipeline Company, L.L.C., an unconsolidated affiliate in which we have a 36 percent joint venture ownership interest, is party to a $185 million credit agreement, under which it has $127 million outstanding, that may restrict its ability to pay distributions to its owners. In January 2002, Poseidon entered into a two-year interest rate swap agreement to fix the variable LIBOR based interest rate on $75 million of the $127 million outstanding under its credit facility at 3.49% through January 2004. Under its credit facility, Poseidon currently pays an additional 1.50% over LIBOR resulting in an effective interest rate of 4.99% on the hedged notional amount. As of March 31, 2003, the remaining $52 million was at an average interest rate of 2.81%. As of March 31, 2003, Deepwater Gateway, an unconsolidated affiliate in which we have a 50 percent joint venture ownership interest, had $67 million outstanding under its project finance loan at an average interest rate of 3.11%. This project finance loan will mature in July 2004 unless construction is completed before that time and Deepwater Gateway meets other specified conditions, in which case the project finance 10

loan will convert into a term loan with a final maturity date of July 2009. Upon conversion of the project finance loan to a term loan, Deepwater Gateway will be required to maintain a debt service reserve equal or greater than the projected principal, interest and fees due on the term loan for the immediately succeeding six month period. Prior to conversion to the term loan Deepwater Gateway is prohibited from making distributions.

6. COMMITMENTS AND CONTINGENCIES Legal Proceedings Grynberg. In 1997, we were named defendants in actions brought by Jack Grynberg on behalf of the U.S. Government under the False Claims Act. Generally, these complaints allege an industry-wide conspiracy to underreport the heating value as well as the volumes of the natural gas produced from federal and Native American lands, which deprived the U.S. Government of royalties. The plaintiff in this case seeks royalties that he contends the government should have received had the volume and heating value of natural gas produced from royalty properties been differently measured, analyzed, calculated and reported, together with interest, treble damages, civil penalties, expenses and future injunctive relief to require the defendants to adopt allegedly appropriate gas measurement practices. No monetary relief has been specified in this case. These matters have been consolidated for pretrial purposes (In re: Natural Gas Royalties Qui Tam Litigation, U.S. District Court for the District of Wyoming, filed June 1997). In May 2001, the court denied the defendants' motions to dismiss. Discovery is proceeding. Our costs and legal exposure related to those lawsuits and claims are not currently determinable. Will Price (formerly Quinque). We have also been named defendants in Quinque Operating Company, et al v. Gas Pipelines and Their Predecessors, et al, filed in 1999 in the District Court of Stevens County, Kansas. Quinque has been dropped as a plaintiff and Will Price has been added. This class action complaint alleges that the defendants mismeasured natural gas volumes and heating content of natural gas on non-federal and non-Native American lands. The plaintiff in this case seeks certification of a nationwide class of natural gas working interest owners and natural gas royalty owners to recover royalties that the plaintiff contends these owners should have received had the volume and heating value of natural gas produced from their properties been differently measured, analyzed, calculated and reported, together with prejudgment and postjudgment interest, punitive damages, treble damages, attorney's fees, costs and expenses, and future injunctive relief to require the defendants to adopt allegedly appropriate gas measurement practices. No monetary relief has been specified in this case. Plaintiffs motion for class certification was denied in April 2003. Our costs and legal exposure related to this lawsuit are not currently determinable. In connection with our April 2002 acquisition of the EPN Holding assets, subsidiaries of El Paso Corporation have agreed to indemnify us against all obligations related to existing legal matters at the acquisition date, including the legal matters involving Leapartners, L.P., City of Edinburg, Houston Pipe Line Company LP, and City of Corpus Christi discussed below. 11

During 2000, Leapartners, L.P. filed a suit against El Paso Field Services and others in the District Court of Loving County, Texas, alleging a breach of contract to gather and process natural gas in areas of western Texas related to an asset now owned by GulfTerra Holding. In May 2001, the court ruled in favor of Leapartners and entered a judgment against El Paso Field Services of approximately $10 million. El Paso Field Services has filed an appeal with the Eighth Court of Appeals in El Paso, Texas. Briefs have been filed and oral arguments were heard in November 2002. Review by the Court of Appeals is expected in 2003. Also, GulfTerra Texas Pipeline L.P., (GulfTerra Texas, formerly known as EPGT Texas Pipeline L.P.) now owned by GulfTerra Holding, is involved in litigation with the City of Edinburg concerning the City's claim that GulfTerra Texas was required to pay pipeline franchise fees under a contract the City had with Rio Grande Valley Gas Company, which was previously owned by GulfTerra Texas and is now owned by Southern Union Gas Company. An adverse judgment against Southern Union and GulfTerra Texas was rendered in Hidalgo County State District court in December 1998 and found a breach of contract, and held both GulfTerra Texas and Southern Union jointly and severally liable to the City for approximately $4.7 million. The judgment relies on the single business enterprise doctrine to impose contractual obligations on GulfTerra Texas and Southern Union's entities that were not parties to the contract with the City. GulfTerra Texas has appealed this case to the Texas Supreme Court seeking reversal of the judgment rendered against GulfTerra Texas. The City seeks a remand to the trial court of its claim of tortious interference against GulfTerra Texas. Briefs have been filed and oral arguments were held in November 2002, and we are awaiting a decision. In December 2000, a 30-inch natural gas pipeline jointly owned by GulfTerra Intrastate, L.P. (GulfTerra Intrastate, formerly known as El Paso Energy Intrastate) now owned by GulfTerra Holding, and Houston Pipe Line Company LP ruptured in Mont Belvieu, Texas, near Baytown, resulting in substantial property damage and minor physical injury. GulfTerra Intrastate is the operator of the pipeline. Two lawsuits were filed in the state district court in Chambers County, Texas by eight plaintiffs, including two homeowners' insurers. The suits seek recovery for physical pain and suffering, mental anguish, physical impairment, medical expenses, and property damage. Houston Pipe Line Company has been added as an additional defendant. In accordance with the terms of the operating agreement, GulfTerra Intrastate has agreed to assume the defense of and to indemnify Houston Pipe Line Company. In September 2002, an agreement was reached to settle the claims of two plaintiffs (including one of the insurers). Trial of five of the six remaining claims is set to commence in May 2003. The City of Corpus Christi, Texas (the "City") is alleging that GulfTerra Texas and various Coastal entities owe it monies for past obligations under City ordinances that propose to tax GulfTerra Texas on its gross receipts from local natural gas sales for the use of street rights-of-way. No lawsuit has been filed to date. Some but not all of the GulfTerra Texas pipe at issue has been using the rights-of-way since the 1960's. In addition, the City demands that GulfTerra Texas agree to a going-forward consent agreement in order for the GulfTerra Texas pipe and Coastal pipe to have the right to remain in City rights-of-way. In addition to the above matters, we and our subsidiaries and affiliates are named defendants in numerous lawsuits and governmental proceedings that arise in the ordinary course of our business. For each of our outstanding legal matters, we evaluate the merits of the case, our exposure to the matter, possible legal or settlement strategies and the likelihood of an unfavorable outcome. If we determine that an unfavorable outcome is probable and can be estimated, we will establish the necessary accruals. As of March 31, 2003, we had no reserves for our legal matters. While the outcome of our outstanding legal matters cannot be predicted with certainty, based on information known to date, we do not expect the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows. As new information becomes available or relevant developments occur, we will establish accruals as appropriate. The impact of these changes may have a material effect on our results of operations. 12

Environmental Each of our operating segments is subject to extensive federal, state, and local laws and regulations governing environmental quality and pollution control. These laws and regulations are applicable to each segment and require us to remove or remedy the effect on the environment of the disposal or release of specified substances at current and former operating sites. As of March 31, 2003, we had a reserve of approximately $21 million for remediation costs expected to be incurred over time associated with mercury meters. We assumed this liability in connection with our April 2002 acquisition of the EPN Holding assets. El Paso Corporation has agreed to indemnify us for all the known and unknown environmental liabilities related to the assets we purchased as part of the November 2002 San Juan assets acquisition up to the purchase price of $766 million. We will only be indemnified for unknown liabilities for up to three years from the purchase date. In addition, we have been indemnified by third parties for remediation costs associated with other assets we have purchased. We expect to make capital expenditures for environmental matters of approximately $10 million in the aggregate for the years 2003 through 2007, primarily to comply with clean air regulations. While the outcome of our outstanding environmental matters cannot be predicted with certainty, based on the information known to date and our existing accruals, we do not expect the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows. It is possible that new information or future developments could require us to reassess our potential exposure related to environmental matters. We may incur significant costs and liabilities in order to comply with existing environmental laws and regulations. It is also possible that other developments, such as increasingly strict environmental laws and regulations and claims for damages to property, employees, other persons and the environment resulting from our current or past operations, could result in substantial costs and liabilities in the future. As this information becomes available, or relevant developments occur, we will adjust our accrual amounts accordingly. While there are still uncertainties relating to the ultimate costs we may incur, based upon our evaluation and experience to date, we believe our current reserves are adequate. Rates and Regulatory Matters Marketing Affiliate NOPR. In September 2001, the Federal Energy Regulatory Commission (FERC) issued a Notice of Proposed Rulemaking (NOPR). The NOPR proposes to apply the standards of conduct governing the relationship between interstate pipelines and marketing affiliates to all energy affiliates. Since our High Island Offshore System (HIOS) and Petal Gas Storage facility are interstate facilities as defined by the Natural Gas Act, the proposed regulations, if adopted by FERC, would dictate how HIOS and Petal conduct business and interact with all of our energy affiliates and El Paso Corporation's energy affiliates. In December 2001, we filed comments with the FERC addressing our concerns with the proposed rules. A public hearing was held in May 2002, providing an opportunity to comment further on the NOPR. Following the conference, we filed additional comments. At this time, we cannot predict the outcome of the NOPR, but adoption of the regulations in the form proposed would, at a minimum, place additional administrative and operational burdens on us. If the standards of conduct NOPR is adopted by the FERC, we will be required to functionally separate our HIOS and Petal interstate facilities from our other businesses. Under the proposed rule, we would be required to dedicate employees to manage and operate our interstate facilities independently from our other non-jurisdictional facilities. This employee group would be required to function independently and would be prohibited from communicating non-public transportation information to affiliates. Separate office facilities and systems would be necessary because of the requirement to restrict affiliate access to interstate transportation information. The NOPR also limits the sharing of employees and officers with non-regulated entities. Because of the loss of synergies and shared employee restrictions, a disposition of the interstate facilities may be necessary for us to effectively comply with the rule. At this time, we cannot predict the outcome of this NOPR. Negotiated Rate NOI. In July 2002, the FERC issued a Notice of Inquiry (NOI) that seeks comments regarding its 1996 policy of permitting pipelines to enter into negotiated rate transactions. The FERC is now 13

reviewing whether negotiated rates should be capped, whether or not the "recourse rate" (a cost-of-service based rate) continues to safeguard against a pipeline exercising market power, and as other issues related to negotiated rate programs. At this time, we cannot predict the outcome of this NOI. Cash Management NOPR. In August 2002, the FERC issued a NOPR requiring that all cash management or money pool arrangements between a FERC regulated subsidiary and a non-FERC regulated parent must be in writing, and set forth the duties and responsibilities of cash management participants and administrators; the methods of calculating interest and for allocating interest income and expenses; and the restrictions on deposits or borrowings by money pool members. The NOPR also requires specified documentation for all deposits into, borrowings from, interest income from, and interest expenses related to, these arrangements. Finally, the NOPR proposes that as a condition of participating in a cash management or money pool arrangement, the FERC regulated entity must maintain a minimum proprietary capital balance of 30 percent, and the FERC regulated entity and its parent must maintain investment grade credit ratings. In August 2002 comments were filed. The FERC held a public conference in September 2002. Representatives of companies from the gas and electric industries participated on a panel and uniformly agreed that the proposed regulations should be revised substantially and commented that the proposed capital balance and investment grade credit rating requirements would be excessive. At this time, we cannot predict the outcome of this NOPR. Also in August 2002, FERC's Chief Accountant issued an Accounting Release, to be effective immediately, providing guidance on how companies should account for money pool arrangements and the types of documentation that should be maintained for these arrangements. However, the Accounting Release did not address the proposed requirements that the FERC regulated entity maintain a minimum proprietary capital balance of 30 percent and that the entity and its parent have investment grade credit ratings. Requests for rehearing were filed in August 2002. The FERC has not yet acted on the rehearing requests. If the cash management NOPR is adopted by the FERC, our HIOS and Petal interstate facilities will no longer be permitted to participate in a money pool or cash management program. As a result, more frequent distributions or equity contributions may be needed in anticipation of monthly cash flow requirements for those interstate facilities. Also, separate credit facilities and resources may be required to support the capital and day-to-day activities for the interstate facilities separate from other of our subsidiaries and our primary bank accounts. Emergency Reconstruction of Interstate Natural Gas Facilities NOPR. In April 2002, FERC and the Department of Transportation, Office of Pipeline Safety convened a technical conference to discuss how to clarify, expedite, and streamline permitting and approvals for interstate pipeline reconstruction in the event of disaster, whether natural or otherwise. In January 2003, FERC issued a NOPR proposing to (1) expand the scope of construction activities authorized under a pipeline's blanket certificate to allow replacement of mainline facilities; (2) authorize a pipeline to commence reconstruction of the affected system without a waiting period; and (3) authorize automatic approval of construction that would be above the normal cost ceiling. Comments on the NOPR were filed on February 27, 2003. At this time we cannot predict the outcome of this NOPR. Pipeline Safety Notice of Proposed Rulemaking. In January 2003, the U.S. Department of Transportation issued a NOPR proposing to establish a rule requiring pipeline operators to develop integrity management programs to comprehensively evaluate their pipelines, and take measures to protect pipeline segments located in what the notice refers to as "high consequence areas." The proposed rule resulted from the enactment of the Pipeline Safety Improvement Act of 2002, a new bill signed into law in December 2002. Comments on the NOPR were due on April 30, 2003. At this time, we cannot predict the outcome of this NOPR. Other Regulatory Matters. HIOS is subject to the jurisdiction of the FERC in accordance with the Natural Gas Act of 1938 and the Natural Gas Policy Act of 1978. HIOS operates under a separate FERC approved tariff that governs its operations, terms and conditions of service, and rates. We timely filed a required rate case for HIOS on December 31, 2002. The rate filing and tariff changes are based on HIOS' cost of service, which includes operating costs, a management fee and changes to depreciation rates and negative salvage amortization. HIOS' filing reflects zero rate base; therefore, we requested a management fee in place 14

of a return on rate base. We requested the rates be effective February 1, 2003, but the FERC suspended the rate increase until July 1, 2003, subject to refund. We have responded, and are continuing to respond, as new requests are received, to the FERC staff's data requests. The FERC has scheduled a hearing on this matter commencing November 17, 2003. During the latter half of 2002, we experienced a significant variance between the fuel usage on HIOS and the fuel collected from our customers. We believe a series of events may have contributed to this variance, including two major storms that hit the Gulf Coast Region (and these assets) in late September and early October of 2002. We are taking numerous steps to determine the cause of the fuel differences, including a review of receipt and delivery measurement data. At March 31, 2003, we had recorded fuel differences of approximately $8.2 million included in other non-current assets. Depending on the outcome of our review, we may require FERC approval to collect the fuel differences. At this time we are not able to determine what amount, if any, may be collectible from our customers. In June 2002, Petal Gas Storage, which is also subject to the FERC's jurisdiction, filed with the FERC a certificate application to add additional gas storage capacity to Petal's storage system. The filing included a new storage cavern with a working gas capacity of 5 Bcf, the conversion and enlargement of an existing subsurface brine storage cavern to a gas storage cavern with a working capacity of 3 Bcf and related surface facilities, natural gas, water and brine transmission lines. In February 2003, the FERC approved the facilities proposed by Petal. In December 1999, GulfTerra Texas filed a petition with the FERC for approval of its rates for interstate transportation service. In June 2002, the FERC issued an order that required revisions to GulfTerra Texas' proposed maximum rates. The changes ordered by the FERC involve reductions to rate of return, depreciation rates and revisions to the proposed rate design, including a requirement to separately state rates for gathering service. FERC also ordered refunds to customers for the difference, if any, between the originally proposed levels and the revised rates ordered by the FERC. We believe the amount of any rate refund would be minimal since most transportation services are discounted from the maximum rate. GulfTerra Texas has established a reserve for refunds. In July 2002, GulfTerra Texas requested rehearing on certain issues raised by the FERC's order, including the depreciation rates and the requirement to separately state a gathering rate. GulfTerra Texas' request for rehearing has been granted and is pending before the FERC. In July 2002, Falcon Gas Storage also requested late intervention and rehearing of the order. Falcon asserts that GulfTerra Texas' imbalance penalties and terms of service preclude third parties from offering imbalance management services. Meanwhile in December 2002, GulfTerra Texas amended its Statement of Operating Conditions to provide shippers the option of resolving daily imbalances using a third-party imbalance service provider. Falcon objected to the changes, complaining that imbalance resolution is the lowest priority of service. GulfTerra Texas responded to Falcon's objection and untimely intervention, repeating its request that Falcon's intervention be dismissed. In December 2002, GulfTerra Texas requested FERC approval of market-based rates for interstate gas storage services performed at its Wilson storage facility. The filing was in compliance with a requirement to rejustify its existing rates or request new rates by December 20, 2002. The requested market-based rates are currently subject to refund. Falcon also intervened in this filing, complaining that market-based rates should be denied because of their complaint about access on the GulfTerra Texas pipeline for third party imbalance services. We filed a response stating that their complaint is not relevant to the rate case, that a severance of this issue has been requested in the GulfTerra Texas pipeline rate case, and requesting a dismissal of their intervention. This matter is pending before the FERC. While the outcome of all of our rates and regulatory matters cannot be predicted with certainty, based on information known to date, we do not expect the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows. As new information becomes available or relevant developments occur, we will review our accruals and make any appropriate adjustments. The impact of these changes may have a material effect on our results of operations. 15

Guarantees We conduct our businesses through our wholly-owned subsidiaries, joint ventures and other ownership arrangements to construct, operate and finance the development of our onshore and offshore midstream energy businesses. Third parties routinely require us to provide performance and financial guarantees to support the obligations of our subsidiaries under contracts entered into in connection with our business. The events and circumstances that may require us, on behalf of our subsidiaries, to perform under these guarantees include nonperformance by our joint ventures and other affiliates of services, such as gathering, transportation, processing and storage services, and nonpayment of contractual obligations. As of March 31, 2003, we had approximately $137.9 million of performance guarantees in connection with the activities of our joint ventures and other affiliates. Such contingent obligations are not recorded in our consolidated financial statements unless they become payable. The most significant of our performance guarantee commitments is related to the construction of the Marco Polo TLP facility. We have guaranteed the payment of approximately $51 million as of March 31, 2003, under the turnkey construction contract between Deepwater Gateway and the construction contractor. We are obligated to perform under this guarantee should Deepwater Gateway fail to satisfy its obligations by drawing under its $155 million project finance loan or Deepwater Gateway's joint venture partners fail to perform under their joint venture agreement. Our commitment under this guarantee is scheduled to expire in 2003. We are also obligated under an agreement with certain lenders to make payments on behalf of Deepwater Gateway to the extent of any distributions we or any of our subsidiaries receive from Deepwater Gateway up to $22.5 million, if Deepwater Gateway defaults on its payment obligations under its project finance loan. Neither we nor any of our subsidiaries have received any distributions from Deepwater Gateway as March 31, 2003. Other Matters Falcon Gas Storage Company, Inc. and its affiliate Hill-Lake Gas Storage, L.P. ("Falcon") filed a formal complaint in March 2003 at the Railroad Commission of Texas claiming that GulfTerra Texas' imbalance penalties and terms of service preclude third parties from offering hourly imbalance management services on the GulfTerra Texas system. GulfTerra Texas filed a response specifically denying Falcon's assertions and requesting that the complaint be denied. As a result of current circumstances generally surrounding the energy sector, the creditworthiness of several industry participants has been called into question. As a result of these general circumstances, we have established an internal group to monitor our exposure to and determine, as appropriate, whether we should request prepayments, letters of credit or other collateral from our counterparties. 7. ACCOUNTING FOR HEDGING ACTIVITIES A majority of our commodity purchases and sales, which relate to sales of oil and natural gas associated with our production operations, purchases and sales of natural gas associated with our El Paso Intrastate Alabama (EPIA) pipeline and sales of liquids associated with our interest in the Indian Basin processing plant, are at spot market or forward market prices. We use futures, forward contracts, and swaps to limit our exposure to fluctuations in the commodity markets and allow for a fixed cash flow stream from these activities. In August 2002, we entered into a derivative financial instrument to hedge our exposure during 2003 to changes in natural gas prices relating to gathering activities in the San Juan Basin in anticipation of our acquisition of the San Juan assets. The derivative is a financial swap on 30,000 MMBtu per day whereby we receive a fixed price of $3.525 per MMBtu and pay a floating price based on the San Juan index. Beginning with the acquisition date in November 2002, we are accounting for this derivative as a cash flow hedge under SFAS No. 133. In February 2003, we entered into an additional derivative financial instrument to continue to hedge our exposure during 2004 to changes in natural gas prices relating to gathering activities in the San Juan Basin. The derivative is a financial swap on 15,000 MMBtu per day whereby we receive a fixed price of $3.95 per MMBtu and pay a floating price based on the San Juan index. We are accounting for this derivative as a 16

cash flow hedge under SFAS No. 133. As of March 31, 2003, the fair value of these cash flow hedges was a liability of $10.8 million. For the quarter ended March 31, 2003, we reclassified a loss of $4.1 million from accumulated other comprehensive income to earnings. No ineffectiveness exists in our hedging relationship because all purchase and sale prices are based on the same index and volumes as the hedge transaction. We estimate the entire amount will be reclassified from accumulated other comprehensive income to earnings over the next 21 months and approximately $8.9 million will be reclassified to earnings over the next twelve months. At March 31, 2003, in connection with our EPIA operations, we have fixed price contracts with specific customers for the sale of predetermined volumes of natural gas for delivery over established periods of time. We entered into cash flow hedges in 2002 and 2003 to offset the risk of increasing natural gas prices. As of March 31, 2003, the fair value of these cash flow hedges was an asset of approximately $192 thousand. For the quarter ended March 31, 2003, the majority of these cash flow hedges expired and we reclassified a gain of $210 thousand from accumulated other comprehensive income to earnings. No ineffectiveness exists in our hedging relationship because all purchase and sale prices are based on the same index and volumes as the hedge transaction. We estimate the entire amount will be reclassified from accumulated other comprehensive income to earnings over the next quarter. In January 2002, Poseidon entered into a two-year interest rate swap agreement to fix the variable LIBOR based interest rate on $75 million of its $185 million variable rate revolving credit facility at 3.49% over the life of the swap. Under its credit facility, Poseidon pays an additional 150 basis points over LIBOR resulting in an effective interest rate at 4.99% on the hedged notional amount. As of March 31, 2003, the fair value of its interest rate swap was a liability of $1.0 million resulting in accumulated other comprehensive loss of $1.0 million. We included our 36 percent share of this liability of $0.4 million as a reduction of our investment in Poseidon and as a loss in accumulated other comprehensive income which we estimate will be reclassified to earnings proportionately over the next nine months. Additionally, we have recognized in income our 36 percent share of Poseidon's realized loss of $0.4 million for the quarter ended March 31, 2003, or $0.1 million, through our earnings from unconsolidated affiliates. The counterparty for our San Juan hedging activities is J. Aron and Company, a subsidiary of Goldman Sachs. We do not require collateral and do not anticipate non-performance by this counterparty. The counterparty for our EPIA hedging activities is El Paso Merchant Energy, an affiliate of our general partner. We do not require collateral and do not anticipate non-performance by this counterparty. The counterparty for Poseidon's hedging activity is Credit Lyonnais. Poseidon does not require collateral and does not anticipate non-performance by this counterparty. 8. BUSINESS SEGMENT INFORMATION Each of our segments are business units that offer different services and products that are managed separately since each segment requires different technology and marketing strategies. We have segregated our business activities into four distinct operating segments: - Natural gas pipelines and plants; - Oil and NGL logistics; - Natural gas storage; and - Platform services. As a result of our sale of the Prince TLP and our nine percent overriding royalty interest in the Prince Field in April 2002, the results of operations from these assets are reflected as discontinued operations in our statements of income for all periods presented. Accordingly, the segment results reflect neither the results of operations for the Prince assets nor the related assets held for sale. We measure segment performance using earnings before interest, income taxes, depreciation and amortization (EBITDA), which we formerly referred to as "Performance Cash Flows," or an asset's ability to generate income. EBITDA is used in the evaluation of our businesses and should not be considered as an 17

alternative to net income as an indicator of our operating performance. EBITDA may not be a comparable measurement among different companies. Following are results as of and for the periods ended March 31: QUARTER ENDED MARCH 31, 2003

QUARTER ENDED MARCH 31, ----------------- 2003 2002 ------- ------- (IN THOUSANDS) Revenues received from related parties Natural gas pipelines and plants.......................... $22,950 $ 9,176 Oil and NGL logistics..................................... 6,869 6,233 Other..................................................... -- 2,918 ------- ------- $29,819 $18,327 ======= ======= Expenses paid to related parties Cost of natural gas....................................... $14,975 $ 8,401 Operating expenses........................................ 23,717 8,800 ------- ------- $38,692 $17,201 ======= ======= Reimbursements received from related parties Operating expenses........................................ $ 525 $ 525 ======= =======
There have been no changes to our related party relationships, except as described below, from those described in Note 9 of our audited financial statements filed in our 2002 Form 10-K. In the first quarter of 2003, our related party revenue was 11 percent of total revenue compared to 30 percent in the first quarter of 2002. Our total revenues for the first quarter of 2003 have increased as a result of our acquisitions during 2002. Also, we have undertaken efforts to reduce our related party revenue with affiliates of El Paso Corporation by replacing our month-to-month, market price sales of natural gas with similar arrangements with third parties. Revenue from these types of sales for the first quarter of 2003 were approximately $3 million compared to approximately $22.2 million in the fourth quarter of 2002. Revenues received from related parties Our revenues from related parties increased as a result of our April 2002 EPN Holding transaction in which we acquired gathering, transportation and processing contracts with affiliates of our general partner. Our expenses paid to related parties increased as a result of our April 2002 EPN Holding transaction and November 2002 San Juan transaction. Other Matters In addition to the related party transactions discussed above, pursuant to the terms of many of the purchase and sale agreements we have entered into with various entities controlled directly or indirectly by El Paso Corporation, we have been indemnified for potential future liabilities, expenses and capital requirements above a negotiated threshold. Specifically, an indirect subsidiary of El Paso Corporation has indemnified us for specific litigation matters to the extent the ultimate resolutions of these matters result in judgments against us. For a further discussion of these matters see Note 6, Commitments and Contingencies, Legal Proceedings. Some of our agreements obligate certain indirect subsidiaries of El Paso Corporation to pay for capital costs related to maintaining assets which were acquired by us, if such costs exceed negotiated thresholds. We have made no such claims for reimbursement to date but may make claims based on our 2002 expenditures and on our expected 2003 expenditure requirements. We have also entered into capital contribution arrangements with regulated pipelines owned by El Paso Corporation in the past, and will most likely do so in the future, as part of our normal commercial activities in the Gulf of Mexico. Regulated pipelines often contribute capital toward the construction costs of gathering 20

facilities owned by others which are connected to their pipelines. We have agreements with ANR Pipeline Company and Tennessee Gas Pipeline Company under which we will receive a total of approximately $25 million of capital toward the construction of gathering pipelines to the Marco Polo, Phoenix and Medusa discoveries, payable over the next eighteen months. The following table provides summary data categorized by our related parties:

12. NEW ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED In April 2003, the FASB issued SFAS No. 149, Amendment of Statement 133 on Derivative Instruments and Hedging Activities. This statement amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities. The statement is effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003, except for provisions that relate to SFAS No. 133 implementation issues that have been effective for fiscal quarter that began prior to June 15, 2003, which are applicable on their respective effective dates. We are required to adopt the provisions of this statement prospectively, unless otherwise prescribed. We are currently evaluating the effects of this pronouncement. 29

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The information contained in Item 2 updates, and you should read it in conjunction with, information disclosed in Part II, Items 7, 7A and 8, in our Annual Report on Form 10-K for the year ended December 31, 2002, in addition to the interim financial statements and notes presented in Item 1 of this Quarterly Report on Form 10-Q. NAME CHANGE In May 2003 we changed our name to GulfTerra Energy Partners, L.P. (NYSE: GTM) from El Paso Energy Partners, L.P. (NYSE: EPN). In connection with our name change, we have also changed the names of several subsidiaries. See Note 1. Financial Statements. Our new name reflects the breadth and depth of our business activities, including our pipelines and platforms in the waters of the Gulf of Mexico to thousands of miles of gathering and transportation lines in the southwest, our asset base spans the midstream. The Gulf portion of our new name represents our origins ten years ago offshore in the Gulf of Mexico -- the extensive infrastructure base we have built over the past decade to meet the needs of Gulf producers and the near limitless potential remaining for growth in the critically important Deep Water trend of the Gulf of Mexico. The Terra portion of our name reflects the other aspect of our diverse midstream asset base including the pipelines, processing and treating plants, and storage facilities located onshore. Terra also represents the rock-solid strategy that has delivered years of outstanding results for our unitholders. GENERAL PARTNER RELATIONSHIP Our corporate governance structure and independence initiatives We continually strive to improve our corporate governance model. During the first quarter of 2003, we identified and evaluated a number of changes that could be made to our corporate structure to better address potential conflicts of interest and to better balance the risks and rewards of significant relationships with our affiliates, which we refer to as Independence Initiatives. Through May 2003, we have implemented the following: - added an additional independent director to our board of directors, bringing the number of independent directors to four of the six-member board; - established a governance and compensation committee of our board of directors consisting solely of independent directors; - changed our name to GulfTerra Energy Partners, L.P.; - received a letter of credit from El Paso Merchant Energy North America totaling $5.1 million regarding our existing customer/contractual relationships with them; - modified our partnership agreement to: (1) eliminate El Paso Corporation's right to vote its common units with respect to the removal of the general partner; (2) increase the common unit vote to 67 percent from 55 percent to remove the general partner; and (3) require the unanimous vote of our general partner's board of directors to voluntarily file the general partner or the partnership into bankruptcy; - completed a resource support agreement with El Paso Corporation; and - reorganized our structure, further reducing our interrelationships with El Paso Corporation, into GulfTerra Energy Company, L.L.C., a Delaware limited liability company that is required to have: - no material assets other than its interests in us; - no material operations other than those relating to our operations; - no material debt or other obligations other than those owed to us or our creditors; 30

- no material liens other than those securing obligations owed to us or our creditors; and - no employees. We are in the process of implementing the following Independence Initiatives: - adding one more independent director to the board of directors, and - negotiating a master netting agreement that could partially mitigate our risks associated with our ongoing contractual arrangements with El Paso Corporation or any of its subsidiaries. Approval must be received from our general partner's board of directors and from El Paso Corporation prior to executing the master netting agreement. Under the partnership agreement, our general partner has agreed not to voluntarily withdraw as general partner prior to December 31, 2002. Now that this obligation has expired, our general partner can withdraw with 90 days notice. We have no employees today, a condition that is common among MLPs. Although this arrangement has worked well for us in the past and continues to work well for us, we are evaluating the direct employment of the personnel who manage the day-to-day operations of our assets. Our relationship with El Paso Corporation El Paso Corporation, a NYSE-listed company, is a leading provider of natural gas services and the largest pipeline company in North America. Through its subsidiaries, El Paso Corporation: - owns 100 percent of our general partner; however, El Paso Corporation has publicly announced that it intends to sell up to ten percent of its general partner interest. - is a significant stake-holder in us -- it owns approximately 26.5 percent, or 11,674,245, of our common units (which decreased to 24.6 percent as a result of our April 2003 common unit offering), all 10,937,500 of our newly issued Series C units, which we issued in November 2002 for $350 million, all 125,392 of our outstanding Series B preference units, with a liquidation value of approximately $161 million at March 31, 2003 (which decreased to 124,584 Series B preference units, with a liquidation value of approximately $160 million as a result of El Paso Corporation's contribution to us of approximately $1 million in liquidation value of Series B preference units to maintain its one percent general partner interest in conjunction with our April 2003 common unit offering) and our one percent general partner interest. - is a customer of ours. As with other large energy companies, we have entered into a number of contracts with El Paso Corporation and its affiliates. - has in the past publicly announced its intention to use us as its primary vehicle for growth and development of its midstream energy business; however, El Paso Corporation is neither contractually nor legally bound to use us as its primary vehicle for growth and development of midstream energy assets, and may reconsider its relationship with us any time, without notice. As discussed previously, we have implemented, and are in the process of implementing, a number of Independence Initiatives that are designed to help us better manage the rewards and risks relating to our relationship with El Paso Corporation. However, even in the light of these Independence Initiatives or any other arrangements, we may still be adversely affected if El Paso Corporation continues to suffer financial stress. RELATED PARTY TRANSACTIONS In our normal course of business we enter into transactions with various entities controlled directly or indirectly by El Paso Corporation. For the quarter ended March 31, 2003, $10.8 million of our related party revenue came from El Paso Merchant Energy North America Company (Merchant Energy), a direct subsidiary of El Paso Corporation. In November 2002, El Paso Corporation announced its intention to exit the energy trading business. Accordingly, we are in the process of replacing our month-to-month, market priced sales of natural gas to Merchant Energy, which in the quarter ended March 31, 2003 represented revenue of 31

approximately $3.0 million, reduced from $22.2 million for the fourth quarter 2002, with similar arrangements with third parties. In addition, Merchant Energy could sell or transfer to third parties the natural gas transportation and storage agreements they have with us, or Merchant Energy could request a cancellation of the transportation and storage agreements prior to expiration of the relevant agreements. In the quarter ended March 31, 2003, these agreements represented revenue of approximately $7.8 million. As of May 2003, Merchant Energy continues to fully utilize these agreements. In connection with our San Juan assets acquisition, we entered into a 10-year transportation agreement with El Paso Field Services beginning January 1, 2003. Under this agreement, we will receive a fee of $1.5 million per year for transportation on one of our NGL pipelines. See Part I, Financial Information, Note 10 for a further discussion of our related party transactions. LIQUIDITY AND CAPITAL RESOURCES Our ability to execute our growth strategy and complete our projects is dependent upon our access to the capital necessary to fund our projects and acquisitions. During the first quarter of 2003, our business and industry have continued to experience the adverse affects of a challenging economic climate that has persisted since 2002. Our continued success with capital raising efforts, including the formation of joint ventures to share costs and risks, will be the critical factor which determines how much we actually spend. We believe our access to capital resources is sufficient to meet the demands of our current and future operating growth needs and, although we currently intend to make the forecasted expenditures, we may adjust the timing and amounts of projected expenditures as necessary to adapt to changes in the capital markets. CAPITAL RESOURCES As part of our previously announced strategy for 2003 to raise approximately $300 million through the issuance of common units and other equity, we issued 3,450,000 common units in April 2003 for $31.35 per unit and received net proceeds of approximately $103 million. Additionally, our general partner contributed approximately $1 million of liquidation value of Series B preference units to maintain its one percent ownership interest in us, and we retired those Series B preference units. We used the net proceeds from our common unit offering to temporarily reduce amounts outstanding under our $600 million revolving credit facility. In addition to our common unit offering, we are also in negotiations with unaffiliated investors regarding the potential sale of common units and warrants or other rights to purchase common units. While the terms of any such potential sale have not been negotiated, such potential sale could involve an initial sale of $25 to $50 million of equity, with warrants or other rights to purchase as much as $150 million of additional equity over the next several years. Due to the preliminary nature of our negotiations, we cannot assure you when or whether a transaction will be consummated, nor of its ultimate terms. Following our March 2003 repayment of the senior secured acquisition term loan, the amounts outstanding under our revolving credit facility bear interest, at our option, at either (i) 0.75% over the variable base rate (equal to the greater of the prime rate as determined by JP Morgan Chase Bank, the federal funds rate plus 0.5% or the Certificate of Deposit (CD) rate as determined by JP Morgan Chase Bank plus 1.00%); or (ii) 1.75% over LIBOR. For the GulfTerra Holding term credit facility, the amounts outstanding bear interest at 1% over the variable rate described above or LIBOR increased by 2.25%. Prior to our repayment of the senior secured acquisition term loan, the revolving credit facility and the GulfTerra Holding term credit facility both bore interest at 2.25% over the variable rate described above or LIBOR increased by 3.50%. 32

SERIES B PREFERENCE UNITS In connection with our public offering of 3,450,000 common units in April 2003, our general partner contributed, and we retired, 808 Series B preference units with liquidation value of approximately $1 million, including accrued distributions of approximately $0.2 million, to maintain its one percent general partner interest in us. FORECASTED EXPENDITURES We estimate our forecasted expenditures based upon our strategic operating and growth plans, which are also dependent upon our ability to produce or otherwise obtain the capital necessary to accomplish our operating and growth objectives. These estimates may change due to factors beyond our control, such as weather related issues, changes in supplier prices or poor economic conditions. Further, estimates may change as a result of decisions made at a later date, which may include scope changes or decisions to take on additional partners. Our projection of expenditures for the quarter ended March 31, 2003 as presented in our 2002 Annual Report on Form 10-K, was $120 million; however, our actual expenditures were approximately $80 million. We intend to spend the remaining amount in subsequent quarters and have included those amounts in the table below. The table below depicts our estimate of expenditures on projects, acquisitions, operating lease payments and principal repayments of debt obligations through March 31, 2004 (in millions). These expenditures are net of anticipated project financings, contributions in aid of construction and contributions from joint venture partners, including the anticipated formation of a joint venture with a 50 percent partner for the development of our Cameron Highway oil pipeline project, and project financings to fund a portion of the construction costs. We expect to be able to fund these forecasted expenditures from the combination of operating cash flow and funds available under our revolving credit facility. Actual results may vary from these projections. We are contractually committed to the Cameron Highway project whether or not we obtain a partner or project financing.

DEBT REPAYMENT AND OTHER OBLIGATIONS See Part I, Financial Information, Note 5, for a detailed discussion of our debt obligations. The following table presents the timing and amounts of our debt repayment and other obligations for the years following March 31, 2003, that we believe could affect our liquidity (in millions):

We expect to renew our revolving credit facility and raise additional capital during the next year through the issuance of additional common units and obtaining a partner and financing for our Cameron Highway oil pipeline project. We expect to use the proceeds we receive from any additional capital we raise through the issuance of additional common units to reduce amounts outstanding under our credit facilities, to finance growth opportunities and for general partnership purposes. Our ability to raise additional capital may be negatively affected by many factors, including our relationship with El Paso Corporation. CASH FROM OPERATING ACTIVITIES Net cash provided by operating activities was $71.4 million for the quarter ended March 31, 2003, compared to $43.2 million for the same period in 2002. The increase was attributable to operating cash flows generated by our acquisitions of the EPN Holding assets in April 2002 and the San Juan assets in November 2002. CASH FROM INVESTING ACTIVITIES Net cash used in investing activities was approximately $79.0 million for the quarter ended March 31, 2003. Our investing activities include capital expenditures related to the construction of the Marco Polo TLP, the Cameron Highway oil pipeline, and the Falcon Nest fixed-leg platform. The expenditures were partially offset by proceeds of $3.1 million from our sale of a treating facility in February 2003. CASH FROM FINANCING ACTIVITIES Net cash used in financing activities was approximately $16.3 million for the quarter ended March 31, 2003. During 2003, our cash provided by financing activities included the issuances of long-term debt. Cash used in our financing activities included repayments on our senior secured acquisition term loan, our revolving credit facility and other financing obligations, as well as distributions to our partners. 34

ACQUISITIONS During the first quarter of 2003, we recorded additional purchase price adjustments of approximately $4.7 million on our April 2002 EPN Holding asset acquisition related to natural gas imbalances. The following table summarizes our revised allocation of the fair values of the assets acquired and liabilities assumed at April 8, 2002. Our allocation among the assets acquired is based on the results of an independent third-party appraisal.

AT APRIL 8, 2002 -------------- (IN THOUSANDS) Current assets.............................................. $ 2,217 Property, plant and equipment............................... 780,648 Intangible assets........................................... 3,500 -------- Total assets acquired..................................... 786,365 -------- Current liabilities......................................... 27,842 Environmental liabilities................................... 21,136 -------- Total liabilities assumed................................. 48,978 -------- Net assets acquired.................................... $737,387 ========
CONSTRUCTION PROJECTS We are currently constructing the following projects:
CAPITAL EXPENDITURES CAPACITY ------------------------------ -------------------- AS OF NATURAL FORECASTED(1) MARCH 31, 2003 OIL GAS EXPECTED COMPLETION ------------- -------------- --------- -------- ------------------- (IN MILLIONS) (MBBLS/D) (MMCF/D) Medusa Natural Gas Pipeline................. $ 28 $ 20 -- 160 Third Quarter 2003 Marco Polo Tension Leg Platform(2)........... 224 131 120 300 Fourth Quarter 2003 Natural Gas and Oil Pipelines............. 101 29 120 400 First Quarter 2004 Cameron Highway Oil Pipeline(3).............. 458 33 500 -- Third Quarter 2004 Phoenix Gathering System... 63 1 -- 450 Second Quarter 2004
- --------------- (1) Forecasted capital expenditures include 100% of the expected costs and are not reduced for contributions in aid of construction, anticipated project financings and contributions from joint venture partners. We expect to receive from subsidiaries of El Paso Corporation the following: $2 million from Tennessee Gas Pipeline for Medusa, $17.5 million total from El Paso Field Services and ANR Pipeline Company for the Marco Polo pipelines ($6 million which has been received from ANR) and $6.1 million from ANR for Phoenix. (2) This tension leg platform is being constructed by Deepwater Gateway, L.L.C., our 50/50 joint venture with CalDive International. Our share of the forecasted expenditures is approximately $112 million. Forecasted expenditures increased due to increases in gas processing capacity (from 250 to 300 MMcf/d) and oil processing capacity (from 100 to 120 MBbls/d) and a higher builder's risk insurance cost. (3) We have entered into a non-binding letter of intent with Valero Energy Corporation under which Valero would acquire a 50 percent interest in the entity we form to construct, install and own this pipeline. The formation of the joint venture is subject to specific conditions set forth in the letter of intent including negotiating and executing definitive documentation and obtaining mutually acceptable financing. NEWLY ANNOUNCED PROJECTS San Juan Optimization Project. In May 2003, we announced the approval of a $43 million project relating to our San Juan basin assets. The project is expected to be completed in stages through 2006. The 35

project is expected to result in a 130 MMcf/d increase in capacity, added compression to the Chaco processing facility and increased market opportunities through a new interconnect at the tailgate of the Chaco processing facility. OTHER MATTERS As a result of current circumstances generally surrounding the energy sector, the creditworthiness of several industry participants has been called into question, including El Paso Corporation, the indirect parent of our general partner. As a result of these general circumstances, we have established an internal group to monitor our exposure to, and determine, as appropriate, whether we should request prepayments, letters of credit or other collateral from our counterparties. If these general conditions worsen and, as a result, several industry participants file for Chapter 11 bankruptcy protection, it could have a material adverse effect on our financial position, results of operations or cash flows. RESULTS OF OPERATIONS Our business activities are segregated into four distinct operating segments: - Natural gas pipelines and plants; - Oil and NGL logistics; - Natural gas storage; and - Platform services. As a result of our sale of the Prince TLP and our nine percent overriding interest in the Prince Field in April 2002, the results of operations from these assets are reflected as discontinued operations in our statements of income for all periods presented and are not reflected in our segment results below. To the extent possible, results of operations have been reclassified to conform to the current business segment presentation, although these results may not be indicative of the results which would have been achieved had the revised business segment structure been in effect during those periods. Operating revenues and expenses by segment include intersegment revenues and expenses which are eliminated in consolidation. For a further discussion of the individual segments, see Part I, Financial Information, Note 8. We use earnings before interest, income taxes, depreciation and amortization (EBITDA) to assess our consolidated and segment results. EBITDA is our liquidity measure as our lenders are interested in whether we generate sufficient cash to meet our debt obligations as they become due. Accordingly our revolving credit agreement and indentures utilize EBITDA to represent a measure of the cash flows from current operations. Our equity investors generally focus on our capacity to pay distributions or to grow the business, or both. As a result, our ability to generate cash from operations of the business to cover distributions, debt service, as well 36

as to pursue growth opportunities, is an important measure of our liquidity. A reconciliation of this measure to cash flows from operations for our consolidated results is as follows for the quarters ended:

We purchase natural gas from producers at the wellhead for an index price less an amount that compensates us for gathering services. We then sell the natural gas into the open market at points on our system at the same index price. Accordingly, our operating revenues and costs of natural gas are impacted by changes in energy commodity prices, while our margin is unaffected. For these reasons, we believe that gross margin (revenue less cost of natural gas) provides a more accurate and meaningful basis than operating revenue or cost of natural gas for analyzing operating results for this segment. First Quarter 2003 Compared to First Quarter 2002 Natural gas pipelines and plants margin for the quarter ended March 31, 2003, was $79.2 million higher than in the same period in 2002. Approximately $43.0 million of the increase was due to our November 2002 purchase of the San Juan Basin assets and approximately $36.7 million of the increase was due to our April 2002 purchase of the EPN Holding assets. Additionally, margin increased by approximately $1.0 million due to increased production in the Camden Hills and Aconcagua Fields, which deliver natural gas to our Viosca Knoll system, offset by $2.2 million of decreased production on HIOS due to natural decline in the offshore region. Operating expenses excluding depreciation, depletion, and amortization for the quarter ended March 31, 2003, were $22.2 million higher than the same period in 2002 primarily due to our November 2002 acquisition of the San Juan Basin assets and our April 2002 purchase of the EPN Holding assets. Excluding the operating costs of the newly acquired assets, operating expenses decreased by $0.8 million. 38

OIL AND NGL LOGISTICS

- ---------- (1) Represents 100% of the volumes flowing through the pipeline. Our transportation agreement with some of our customers provides that we purchase the oil produced at the inlet of our pipeline for an index price less an amount that compensates us for transportation services. At the outlet of our pipeline, we resell this oil back to these producers at the same index price. We reflect these sales in gathering and processing revenues and the related purchases as cost of oil. For these reasons, we believe that gross margin (revenue less cost of oil) provides a more accurate and meaningful basis than operating revenue or cost of oil for analyzing operating results for this segment. First Quarter 2003 Compared to First Quarter 2002 For the quarter ended March 31, 2003, margin was $3.1 million higher than the same period in 2002 primarily due to our November 2002 acquisition of the Texas NGL facilities and an oil gathering system located in the deep water regions of the Gulf of Mexico, referred to as Typhoon Oil Pipeline, which assets contributed $2.8 million to the increase. Operating expenses excluding depreciation, depletion, and amortization for the quarter ended March 31, 2003, were $1.7 million higher than the same period in 2002 primarily due to our November 2002 acquisition of the Typhoon Oil Pipeline and the Texas NGL facilities offset by the modification of the operating agreement between our subsidiary and El Paso Field Services, which reduced the amount of El Paso Field Services' monthly operating charges to us, in connection with the April 2002 EPN Holding acquisition. 39

NATURAL GAS STORAGE

- ---------- (1) Combined injections and withdrawals volumes. We collect fixed and variable dollars for providing storage services, some of which is generated from customers with cashout provisions, at a tariff-based index calculation. We incur expenses as we maintain these volumetric imbalance receivables and payables which are valued at current gas prices. For these reasons, we believe that gross margin (storage revenues less storage expenses) provides a more accurate and meaningful basis for analyzing operating results for the Natural gas storage segment. First Quarter 2003 Compared to First Quarter 2002 For the quarter ended March 31, 2003, margin was $5.7 million higher than the same period in 2002 primarily due to the expansion of the Petal storage facility and our April 2002 acquisition of the Wilson storage facility lease. Excluding the increase in margin from the Petal expansion and our acquisition of the Wilson storage facility lease, margin was down $1.1 million primarily as a result of a decrease in firm contracts at our Hattiesburg facility. Operating expenses excluding depreciation, depletion, and amortization for the quarter were $1.4 million higher than the same period in 2002 primarily due to the acquisition of the Wilson storage facility lease in April 2002. 40

PLATFORM SERVICES

First Quarter 2003 Compared to First Quarter 2002 For the quarter ended March 31, 2003, revenues were $2.5 million lower than in the same period in 2002 primarily due to the expiration in June 2002, in accordance with the original contract terms, of the fixed fee portion of the Viosca Knoll 817 platform access fee contract with one of our wholly owned subsidiaries and the Garden Banks 72 contract expiration in December 2002. Additionally, revenue decreased due to one time billing adjustments in 2002 for fixed monthly platform access fees and a gas dehydration fee on the East Cameron 373 platform. The decrease was partially offset by the completion of the Falcon Nest fixed leg platform that went into operation in March 2003. Operating expenses for the same periods were $0.4 million higher due to higher maintenance expenses. OTHER, NET First Quarter 2003 Compared to First Quarter 2002 EBITDA related to non-segment activity for the quarter ended March 31, 2003, was $3.2 million higher than the same period in 2002 due to lower platform access fee expense as a result of the expiration in June 2002 of the fixed fee portion of the Viosca Knoll 817 platform access fee contract and the Garden Banks 72 contract expiration in December 2002. These are intercompany contracts as discussed in our Platform services segment. Additionally, revenues increased due to higher natural gas and oil prices. Net income (excluding interest and debt expense and cumulative affect of accounting change, which are not allocated to our segments) for the quarter ended March 31, 2003 was $5 million higher than the same period in 2002 due to lower platform access fee expense and increased revenues as described above. 41

DEPRECIATION, DEPLETION, AND AMORTIZATION Depreciation, depletion, and amortization for the quarter ended March 31, 2003, was $11.2 million higher than the same period in 2002. This increase is primarily due to our November 2002 purchase of the San Juan Basin assets and our April 2002 purchase of the EPN Holding assets. Further contributing to the increase was the completion of the Petal expansion in June 2002, offset by lower depletion on the oil and natural gas producing activities. INTEREST AND DEBT EXPENSE Interest and debt expense, net of capitalized interest, for the quarter ended March 31, 2003, was approximately $22.7 million higher than the same period in 2002. This increase is primarily due to an increase in the average outstanding balance and the weighted average interest of our revolving credit facility, the amounts outstanding under the GulfTerra Holding term credit facility which we entered to purchase the EPN Holding assets in April 2002, the $230 million of 8.5% senior subordinated notes issued in May 2002, the $200 million 10 5/8% senior subordinated notes issued in November 2002 and the $237.5 million senior secured acquisition term loan, which was repaid in March 2003 with the issuance of our $300 million 8 1/2% senior subordinated notes. Capitalized interest for the quarter ended March 31, 2003 was $1.9 million compared to $1.6 million for the same period in 2002. LOSS DUE TO WRITE-OFF OF DEBT ISSUANCE COST In March 2003, we repaid our $237.5 million senior secured term loan which was due in May 2004 and recognized a loss of $3.8 million related to the write-off of the unamortized debt issuance costs related to this loan.

Important factors that could cause actual results to differ materially from estimates or projections contained in forward-looking statements are described in our Annual Report on Form 10-K for the year ended December 31, 2002, and our other filings with the Securities and Exchange Commission. Where any forward-looking statement includes a statement of the assumptions or bases underlying the forward-looking statement, we caution that, while we believe these assumptions or bases to be reasonable and made in good faith, assumed facts or bases almost always vary from the actual results, and the differences between assumed facts or bases and actual results can be material, depending upon the circumstances. Where, in any forward-looking statement, we express an expectation or belief as to future results, such expectation or belief is expressed in good faith and is believed to have a reasonable basis. We cannot assure you, however, that the statement of expectation or belief will result or be achieved or accomplished. These statements relate to analyses and other information which are based on forecasts of future results and estimates of amounts not yet determinable. These statements also relate to our future prospects, developments and business strategies. These forward-looking statements are identified by their use of terms and phrases such as "anticipate," "believe," "could," "estimate," "expect," "intend," "may," "plan," "predict," "project," "will," and similar terms and phrases, including references to assumptions. These forward-looking statements involve risks and uncertainties that may cause our actual future activities and results of operations to be materially different from those suggested or described. These risks may also be specifically described in our Current Reports on Form 8-K and other documents filed with the Securities and Exchange Commission. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information or otherwise. If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, our actual results may vary materially from those expected, estimated or projected. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK This information updates, and you should read it in conjunction with, our quantitative and qualitative disclosures about market risks reported in our Annual Report on Form 10-K for the year ended December 31, 2002, in addition to information presented in Items 1 and 2 of this Quarterly Report on Form 10-Q and our Current Reports on Form 8-K. In August 2002, we entered into a derivative financial instrument to hedge our exposure during 2003 to changes in natural gas prices relating to gathering activities in the San Juan Basin in anticipation of our acquisition of the San Juan assets. The derivative is a financial swap on 30,000 MMBtu per day whereby we receive a fixed price of $3.525 per MMBtu and pay a floating price based on the San Juan index. Beginning with the acquisition date in November 2002, we are accounting for this derivative as a cash flow hedge under SFAS No. 133. In February 2003, we entered into an additional derivative financial instrument to continue to hedge our exposure during 2004 to changes in natural gas prices relating to gathering activities in the San Juan Basin. The derivative is a financial swap on 15,000 MMBtu per day whereby we receive a fixed price of $3.95 per MMBtu and pay a floating price based on the San Juan index. We are accounting for this derivative as a cash flow hedge under SFAS No. 133. As of March 31, 2003, the fair value of these cash flow hedges was a liability of $10.8 million. For the quarter ended March 31, 2003, we reclassified a loss of $4.1 million from accumulated other comprehensive income to earnings. No ineffectiveness exists in our hedging relationship because all purchase and sale prices are based on the same index and volumes as the hedge transaction. We estimate the entire amount will be classified from accumulated other comprehensive income to earnings over the next 21 months and approximately $8.9 million will be reclassed to earnings over the next twelve months. At March 31, 2003, in connection with our EPIA operations, we have fixed price contracts with specific customers for the sale of predetermined volumes of natural gas for delivery over established periods of time. We entered into cash flow hedges in 2002 and 2003 to offset the risk of increasing natural gas prices. As of March 31, 2003, the fair value of these cash flow hedges was an asset of approximately $192 thousand. For the quarter ended March 31, 2003, the majority of these cash flow hedges expired and we reclassified a gain of $210 thousand from accumulated other comprehensive income to earnings. No ineffectiveness exists in our 43

hedging relationship because all purchase and sale prices are based on the same index and volumes as the hedge transaction. We estimate the entire amount will be reclassified from accumulated other comprehensive income to earnings over the next quarter. In January 2002, Poseidon entered into a two-year interest rate swap agreement to fix the variable LIBOR based interest rate on $75 million of the $127 million outstanding under its credit facility at 3.49% through January 2004. Under its credit facility, Poseidon pays an additional 1.50% over LIBOR resulting in an effective interest rate at 4.99% on the hedged notional amount. As of March 31, 2003, the fair value of its interest rate swap was a liability of $1.0 million resulting in accumulated other comprehensive loss of $1.0 million. We included our 36 percent share of this liability of $0.4 million as a reduction of our investment in Poseidon and as loss in accumulated other comprehensive income which we estimate will be reclassified to earnings proportionately over the next nine months. Additionally, we have recognized in income our 36 percent share of Poseidon's realized loss of $0.4 million for the quarter ended March 31, 2003, or $0.1 million, through our earnings from unconsolidated affiliates. ITEM 4. CONTROLS AND PROCEDURES Evaluation of Controls and Procedures. Under the supervision and with the participation of management, including our principal executive officer and principal financial officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures (Disclosure Controls) and internal controls (Internal Controls) within 90 days of the filing date of this annual report pursuant to Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934 (Exchange Act). Definition of Disclosure Controls and Internal Controls. Disclosure Controls are our controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified under the Exchange Act. Disclosure Controls include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Internal Controls are procedures which are designed with the objective of providing reasonable assurance that (1) our transactions are properly authorized; (2) our assets are safeguarded against unauthorized or improper use; and (3) our transactions are properly recorded and reported, all to permit the preparation of our financial statements in conformity with generally accepted accounting principles. Limitations on the Effectiveness of Controls. Our management, including the principal executive officer and principal financial officer, does not expect that our Disclosure Controls and Internal Controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. No Significant Changes in Internal Controls. We have sought to determine whether there were any "significant deficiencies" or "material weaknesses" in GulfTerra Energy Partners' Internal Controls, or whether GulfTerra Energy Partners had identified any acts of fraud involving personnel who have a significant 44

role in GulfTerra Energy Partners' Internal Controls. This information was important both for the controls evaluation generally and because the principal executive officer and principal financial officer are required to disclose that information to our Board's Audit Committee and our independent auditors and to report on related matters in this section of the Annual Report. The principal executive officer and principal financial officer note that, from the date of the controls evaluation to the date of this Annual Report, there have been no significant changes in Internal Controls or in other factors that could significantly affect Internal Controls, including any corrective actions with regard to significant deficiencies and material weaknesses. Effectiveness of Disclosure Controls. Based on the controls evaluation, our principal executive officer and principal financial officer have concluded that, subject to the limitations discussed above, the Disclosure Controls are effective to ensure that material information relating to GulfTerra Energy Partners and its consolidated subsidiaries is made known to management, including the principal executive officer and principal financial officer, particularly during the period when our periodic reports are being prepared. Officer Certifications. The certifications from the principal executive officer and principal financial officer required under Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 have been included herein, or as Exhibits to this Annual Report, as appropriate. 45

Section 2. Holders. A Person is deemed to be a holder of Transfer Restricted Securities (each, a "Holder") whenever such Person owns Transfer Restricted Securities. Section 3. Registered Exchange Offer. (a) Unless the Exchange Offer shall not be permitted by applicable federal law (after the procedures set forth in Section 6(a)(i) below have been complied with), the Issuers and the Subsidiary Guarantors shall (i) cause the Exchange Offer Registration Statement to be filed with the Commission as soon as practicable after the Closing Date, but in no event later than 95 days after the Closing Date (such 95th day being the "Filing Deadline"), (ii) use its best efforts to cause such Exchange Offer Registration Statement to become effective at the earliest possible time, but in no event later than 150 days after the Closing Date (such 150th day being the "Effectiveness Deadline"), (iii) in connection with the foregoing, (A) file all pre-effective amendments to such Exchange Offer Registration Statement as may be necessary in order to cause it to become effective, (B) file, if applicable, a post-effective amendment to such Exchange Offer Registration Statement pursuant to Rule 430A under the Act and (C) cause all necessary filings, if any, in connection with the registration and qualification of the Series B Notes to be made under the Blue Sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, and (iv) upon the effectiveness of such Exchange Offer Registration Statement, commence and Consummate the Exchange Offer. The Exchange Offer shall be on the appropriate form permitting (i) registration of the Series B Notes to be offered in exchange for the Series A Notes that are Transfer Restricted Securities and (ii) resales of Series B Notes by Broker-Dealers that tendered into the Exchange Offer Series A Notes that such Broker-Dealer acquired for its own account as a result of market making activities or other trading activities (other than Series A Notes acquired directly from the Issuers or any of their Affiliates) as contemplated by Section 3(c) below. 3

(b) The Issuers and the Subsidiary Guarantors shall use their respective best efforts to cause the Exchange Offer Registration Statement to be effective continuously, and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided, however, that in no event shall such period be less than 20 Business Days. The Issuers and the Subsidiary Guarantors shall cause the Exchange Offer to comply with all applicable federal and state securities laws. No securities other than the Series B Notes shall be included in the Exchange Offer Registration Statement. The Issuers and the Subsidiary Guarantors shall use their respective best efforts to cause the Exchange Offer to be Consummated on the earliest practicable date after the Exchange Offer Registration Statement has become effective, but in no event later than 180 days after the Closing Date (such 180th day being the "Consummation Deadline"). (c) The Issuers shall include a "Plan of Distribution" section in the Prospectus contained in the Exchange Offer Registration Statement and indicate therein that any Broker-Dealer who holds Transfer Restricted Securities that were acquired for the account of such Broker-Dealer as a result of market-making activities or other trading activities (other than Series A Notes acquired directly from the Issuers or any Affiliate of the Issuers) may exchange such Transfer Restricted Securities pursuant to the Exchange Offer. Such "Plan of Distribution" section shall also contain all other information with respect to such sales by such Broker-Dealers that the Commission may require in order to permit such sales pursuant thereto, but such "Plan of Distribution" shall not name any such Broker-Dealer or disclose the amount of Transfer Restricted Securities held by any such Broker-Dealer, except to the extent required by the Commission as a result of a change in policy, rules or regulations after the date of this Agreement. Because such Broker-Dealer may be deemed to be an "underwriter" within the meaning of the Act and must, therefore, deliver a prospectus meeting the requirements of the Act in connection with its initial sale of any Series B Notes received by such Broker-Dealer in the Exchange Offer, the Issuers and Subsidiary Guarantors shall permit the use of the Prospectus contained in the Exchange Offer Registration Statement by such Broker-Dealer to satisfy such prospectus delivery requirement. To the extent necessary to ensure that the prospectus contained in the Exchange Offer Registration Statement is available for sales of Series B Notes by such Broker-Dealers, the Issuers and the Subsidiary Guarantors agree to use their respective best efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented, amended and current as required by and subject to the provisions of Sections 6(a) and (c) hereof and in conformity with the requirements of this Agreement, the Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of one year from the Consummation Deadline or such shorter period as will terminate when all Transfer Restricted Securities covered by such Registration Statement have been sold pursuant thereto. The Issuers and the Subsidiary Guarantors shall provide sufficient copies of the latest version of such Prospectus to such Broker-Dealers, promptly upon request, and in no event later than one day after such request, at any time during such period. 4

Section 4. Shelf Registration. (a) Shelf Registration. If (i) the Exchange Offer is not permitted by applicable law (after the Issuers and the Subsidiary Guarantors have complied with the procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of Transfer Restricted Securities shall notify the Issuers within 20 Business Days following the Consummation Deadline that (A) such Holder was prohibited by law or Commission policy from participating in the Exchange Offer or (B) such Holder may not resell the Series B Notes acquired by it in the Exchange Offer to the public without delivering a prospectus and the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder or (C) such Holder is a Broker-Dealer and holds Series A Notes acquired directly from the Issuers or any of their Affiliates, then the Issuers and the Subsidiary Guarantors shall: (x) cause to be filed, on or prior to 30 days after the earlier of (i) the date on which the Issuers determine that the Exchange Offer Registration Statement cannot be filed as a result of clause (a)(i) above and (ii) the date on which the Issuers receive the notice specified in clause (a)(ii) above, (such earlier date, the "Filing Deadline"), a shelf registration statement pursuant to Rule 415 under the Act (which may be an amendment to the Exchange Offer Registration Statement (the "Shelf Registration Statement")), relating to all Transfer Restricted Securities, and (y) shall use their respective best efforts to cause such Shelf Registration Statement to become effective on or prior to 60 days after the Filing Deadline for the Shelf Registration Statement (such 60th day the "Effectiveness Deadline"). If, after the Issuers and the Subsidiary Guarantors have filed an Exchange Offer Registration Statement that satisfies the requirements of Section 3(a) above, the Issuers are required to file and make effective a Shelf Registration Statement solely because the Exchange Offer is not permitted under applicable federal law (i.e., clause (a)(i) above), then the filing of the Exchange Offer Registration Statement shall be deemed to satisfy the requirements of clause (x) above; provided that, in such event, the Issuers and the Subsidiary Guarantors shall remain obligated to meet the Effectiveness Deadline set forth in clause (y). To the extent necessary to ensure that the Shelf Registration Statement is available for sales of Transfer Restricted Securities by the Holders thereof entitled to the benefit of this Section 4(a) and the other securities required to be registered therein pursuant to Section 6(b)(ii) hereof, the Issuers and the Subsidiary Guarantors shall use their respective best efforts to keep any Shelf Registration Statement required by this Section 4(a) continuously effective, supplemented, amended and current as required by and subject to the provisions of Sections 6(b) and (c) hereof and in conformity with the requirements of this Agreement, the Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of at least two years (as extended pursuant to Section 6(d)) 5

following the Closing Date, or such shorter period as will terminate when all Transfer Restricted Securities covered by such Shelf Registration Statement have been sold pursuant thereto. (b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Issuers in writing, within 20 days after receipt of a request therefor, the information specified in Item 507 or 508 of Regulation S-K, as applicable, of the Act for use in connection with any Shelf Registration Statement or Prospectus (or preliminary Prospectus) included therein. No Holder of Transfer Restricted Securities shall be entitled to liquidated damages pursuant to Section 5 hereof unless and until such Holder shall have provided all such information. Each selling Holder agrees to promptly furnish additional information required to be disclosed in order to make the information previously furnished to the Issuers by such Holder not materially misleading. Section 5. Liquidated Damages. If (i) any Registration Statement required by this Agreement is not filed with the Commission on or prior to the applicable Filing Deadline, (ii) any such Registration Statement has not been declared effective by the Commission on or prior to the applicable Effectiveness Deadline, (iii) the Exchange Offer has not been Consummated on or prior to the Consummation Deadline or (iv) any Registration Statement required by this Agreement is filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded within 2 days by a post-effective amendment to such Registration Statement that cures such failure and that is itself declared effective within 2 days of filing such post-effective amendment to such Registration Statement (each such event referred to in clauses (i) through (iv), a "Registration Default"), then the Issuers and the Subsidiary Guarantors hereby jointly and severally agree to pay to each Holder of Transfer Restricted Securities affected thereby liquidated damages in an amount equal to $.05 per week per $1,000 in principal amount of Transfer Restricted Securities held by such Holder for each week or portion thereof that the Registration Default continues for the first 90-day period immediately following the occurrence of such Registration Default. The amount of the liquidated damages shall increase by an additional $.05 per week per $1,000 in principal amount of Transfer Restricted Securities with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of liquidated damages of $.50 per week per $1,000 in principal amount of Transfer Restricted Securities; provided that the Issuers and the Subsidiary Guarantors shall in no event be required to pay liquidated damages for more than one Registration Default at any given time. Notwithstanding anything to the contrary set forth herein, (1) upon filing of the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement), in the case of (i) above, (2) upon the effectiveness of the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement), in the case of (ii) above, (3) upon Consummation of the Exchange Offer, in the case of (iii) above, or (4) upon the filing of a post-effective amendment to the Registration Statement or an additional Registration Statement that causes the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement) to again be declared effective or made usable in the case of (iv) above, the accrual of liquidated damages payable with respect to the 6

Transfer Restricted Securities as a result of such clause (i), (ii), (iii) or (iv), as applicable, shall cease. All accrued liquidated damages shall be paid to the Holders entitled thereto, in the manner providing for the payment of interest in the Indenture, on each Interest Payment Date, as more fully set forth in the Indenture and the Notes; provided however, that any accrued liquidated damages that are unpaid at the time any Notes cease to be Transfer Restricted Securities upon consummation of the Exchange Offer shall be paid on or promptly after the date of such consummation to the Holders of record of such Transfer Restricted Securities on such date. Notwithstanding the fact that any securities for which liquidated damages are due cease to be Transfer Restricted Securities, all obligations of the Issuers and the Subsidiary Guarantors to pay liquidated damages with respect to securities shall survive until such time as such obligations with respect to such securities shall have been satisfied in full. Section 6. Registration Procedures. (a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Issuers and the Subsidiary Guarantors shall (x) comply with all applicable provisions of Section 6(c) below, (y) use their respective best efforts to effect such exchange and to permit the resale of Series B Notes by Broker-Dealers that tendered in the Exchange Offer Series A Notes that such Broker-Dealer acquired for its own account as a result of its market making activities or other trading activities (other than Series A Notes acquired directly from the Issuers or any of their Affiliates) being sold in accordance with the intended method or methods of distribution thereof, and (z) comply with all of the following provisions: (i) If, following the date hereof there has been announced a change in Commission policy with respect to exchange offers such as the Exchange Offer, that in the reasonable opinion of counsel to the Issuers raises a substantial question as to whether the Exchange Offer is permitted by applicable federal law, the Issuers and the Subsidiary Guarantors hereby agree to seek a no-action letter or other favorable decision from the Commission allowing the Issuers and the Subsidiary Guarantors to Consummate an Exchange Offer for such Transfer Restricted Securities. The Issuers and the Subsidiary Guarantors hereby agree to pursue the issuance of such a decision to the Commission staff level. In connection with the foregoing, the Issuers and the Subsidiary Guarantors hereby agree to take all such other actions as may be requested by the Commission or otherwise required in connection with the issuance of such decision, including without limitation (A) participating in telephonic conferences with the Commission, (B) delivering to the Commission staff an analysis prepared by counsel to the Issuers setting forth the legal bases, if any, upon which such counsel has concluded that such an Exchange Offer should be permitted and (C) diligently pursuing a resolution (which need not be favorable) by the Commission staff. (ii) As a condition to its participation in the Exchange Offer, each Holder of Transfer Restricted Securities (including, without limitation, any 7

Holder who is a Broker Dealer) shall furnish, upon the request of the Issuers, prior to the Consummation of the Exchange Offer, a written representation to the Issuers and the Subsidiary Guarantors (which may be contained in the letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an Affiliate of the Issuers, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any Person to participate in, a distribution of the Series B Notes to be issued in the Exchange Offer, (C) it is acquiring the Series B Notes in its ordinary course of business and (D) if the undersigned is a Broker-Dealer, the Series A Notes being tendered constitute Series A Notes acquired as the result of market-making activities or other trading activities (other than Series A Notes acquired directly from the Issuers or any of their Affiliates). As a condition to its participation in the Exchange Offer, each Holder shall acknowledge and agree that (x) any person participating in Exchange Offer with the intention or for the purpose of distributing the Series B Notes, (1) could not, under Commission policy as in effect on the date of this Agreement, rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission's letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters (including, if applicable, any no-action letter obtained pursuant to clause (i) above), and (2) must comply with the registration and prospectus delivery requirements of the Act in connection with a secondary resale transaction and that such a secondary resale transaction must be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K and (y) any Broker-Dealer that pursuant to the Exchange Offer receives Series B Notes for its own account in exchange for Series A Notes which it acquired for its own account as a result of market-making activities or other trading activities must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Series B Notes. (iii) Prior to effectiveness of the Exchange Offer Registration Statement, the Issuers and the Subsidiary Guarantors shall provide a supplemental letter to the Commission (A) stating that the Issuers and the Subsidiary Guarantors are registering the Exchange Offer in reliance on the position of the Commission enunciated in Exxon Capital Holdings Corporation (available May 13, 1988), Morgan Stanley and Co., Inc. (available June 5, 1991) as interpreted in the Commission's letter to Shearman & Sterling dated July 2, 1993, and, if applicable, any no-action letter obtained pursuant to clause (i) above, (B) including a representation that neither the Issuers nor any Subsidiary Guarantor has entered into any arrangement or understanding with any Person to distribute the Series B Notes to be received in the Exchange Offer and that, to the best of the Issuers' and each Subsidiary Guarantor's information and belief, each Holder participating in the Exchange Offer is acquiring the Series B Notes in its ordinary course of business and has no arrangement or understanding with any Person to participate in the distribution of the Series B Notes received in the Exchange Offer and (C) any other undertaking or representation required by the 8

Commission as set forth in any no-action letter obtained pursuant to clause (i) above, if applicable. (b) Shelf Registration Statement. In connection with the Shelf Registration Statement, the Issuers and the Subsidiary Guarantors shall: (i) comply with all the provisions of Section 6(c) below and use their respective best efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof (as indicated in the information furnished to the Issuers pursuant to Section 4(b) hereof), and pursuant thereto the Issuers and the Subsidiary Guarantors will prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof within the time periods and otherwise in accordance with the provisions hereof. (ii) issue, upon the request of any Holder or purchaser of Series A Notes covered by any Shelf Registration Statement contemplated by this Agreement, Series B Notes having an aggregate principal amount equal to the aggregate principal amount of Series A Notes sold pursuant to the Shelf Registration Statement and surrendered to the Issuers for cancellation; the Issuers shall register Series B Notes on the Shelf Registration Statement for this purpose and issue the Series B Notes to the purchaser(s) of securities subject to the Shelf Registration Statement in the names as such purchaser(s) shall designate. (c) General Provisions. In connection with any Registration Statement and any related Prospectus required by this Agreement, the Issuers and the Subsidiary Guarantors shall: (i) use their respective best efforts to keep such Registration Statement continuously effective and provide all requisite financial statements for the period specified in Section 3 or 4 of this Agreement, as applicable. Upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain an untrue statement of material fact or omit to state any material fact necessary to make the statements therein not misleading or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Issuers and the Subsidiary Guarantors shall file promptly an appropriate amendment to such Registration Statement curing such defect, and, if Commission review is required, use their respective best efforts to cause such amendment to be declared effective as soon as practicable; (ii) prepare and file with the Commission such amendments and post-effective amendments to the applicable Registration Statement as may be necessary to keep such Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as the case may be; cause the Prospectus to be 9

supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Act, and to comply fully with Rules 424, 430A and 462, as applicable, under the Act in a timely manner; and comply with the provisions of the Act with respect to the disposition of all securities covered by such Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus; (iii) advise each Holder promptly and, if requested by such Holder, confirm such advice in writing, (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to any applicable Registration Statement or any post-effective amendment thereto, when the same has become effective, (B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement under the Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, and (D) of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Registration Statement, the Prospectus, any amendment or supplement thereto or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Registration Statement in order to make the statements therein not misleading, or that requires the making of any additions to or changes in the Prospectus in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or Blue Sky laws, the Issuers and the Subsidiary Guarantors shall use their respective best efforts to obtain the withdrawal or lifting of such order at the earliest possible time; (iv) subject to Section 6(c)(i), if any fact or event contemplated by Section 6(c)(iii)(D) above shall exist or have occurred, prepare a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; (v) furnish to each Holder in connection with such exchange or sale, if any, before filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all documents incorporated by 10

reference after the initial filing of such Registration Statement), which documents will be subject to the review and comment of such Holders in connection with such sale, if any, for a period of at least five Business Days, and the Issuers will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated by reference) to which such Holders shall reasonably object within five Business Days after the receipt thereof. A Holder shall be deemed to have reasonably objected to such filing if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains an untrue statement of a material fact or omits to state any material fact necessary to make the statements therein not misleading or fails to comply with the applicable requirements of the Act; (vi) promptly provide, prior to the filing of any document that is to be incorporated by reference into a Registration Statement or Prospectus, copies of such document to each Holder in connection with such exchange or sale, if any, make the Issuers' and the Subsidiary Guarantors' representatives available for discussion of such document and other customary due diligence matters, and include such information in such document prior to the filing thereof as such Holders may reasonably request; (vii) make available, at reasonable times, for inspection by each Holder and any attorney or accountant retained by such Holders, all financial and other records, and pertinent corporate documents of the Issuers and the Subsidiary Guarantors and cause the Issuers' and the Subsidiary Guarantors' officers, directors and employees to supply all information reasonably requested by any such Holder, attorney or accountant in connection with such Registration Statement or any post-effective amendment thereto subsequent to the filing thereof and prior to its effectiveness; (viii) if requested by any Holders in connection with such exchange or sale, promptly include in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such Holders may reasonably request to have included therein, including, without limitation, information relating to the "Plan of Distribution" of the Transfer Restricted Securities; and make all required filings of such Prospectus supplement or post-effective amendment as soon as practicable after the Issuers are notified of the matters to be included in such Prospectus supplement or post-effective amendment; (ix) furnish to each Holder in connection with such exchange or sale, without charge, at least one copy of the Registration Statement, as first filed with the Commission, and of each amendment thereto, including all documents incorporated by reference therein and all exhibits (including exhibits incorporated therein by reference); 11

(x) deliver to each Holder without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request; the Issuers and the Subsidiary Guarantors hereby consent to the use (in accordance with law) of the Prospectus and any amendment or supplement thereto by each selling Holder in connection with the offering and the sale of the Transfer Restricted Securities covered by the Prospectus or any amendment or supplement thereto; (xi) upon the request of any Holder, enter into such agreements (including underwriting agreements) and make such representations and warranties and take all such other actions in connection therewith in order to expedite or facilitate the disposition of the Transfer Restricted Securities pursuant to any applicable Registration Statement contemplated by this Agreement as may be reasonably requested by any Holder in connection with any sale or resale pursuant to any applicable Registration Statement. In such connection, the Issuers and the Subsidiary Guarantors shall: (A) upon request of any Holder, furnish (or in the case of paragraphs (2) and (3), use their best efforts to cause to be furnished) to each Holder, upon Consummation of the Exchange Offer or upon the effectiveness of the Shelf Registration Statement, as the case may be: (1) a certificate, dated such date, signed on behalf of the Issuers and each Subsidiary Guarantor by (x) the President or any Vice President and (y) a principal financial or accounting officer of each of the Issuers and each Subsidiary Guarantor, confirming, as of the date thereof, the matters set forth in Sections 6(aa), 9(a) and 9(b) of the Purchase Agreement and such other similar matters as such Holders may reasonably request; (2) an opinion, dated the date of Consummation of the Exchange Offer or the date of effectiveness of the Shelf Registration Statement, as the case may be, of counsel for the Issuers and the Subsidiary Guarantors covering matters similar to those set forth in paragraph (e) of Section 9 of the Purchase Agreement and such other matters as such Holder may reasonably request, and in any event including a statement to the effect that such counsel has participated in conferences with officers and other representatives of the Issuers and the Subsidiary Guarantors, and representatives of the independent public accountants for the Issuers and the Subsidiary Guarantors and have considered the matters required to be stated therein and the statements contained therein, although such counsel has not independently verified the accuracy, completeness or fairness of such statements; and that such counsel advises that, on the basis of the foregoing, no facts came to such counsel's attention that caused such counsel to believe that the applicable Registration Statement, at the time such 12

Registration Statement or any post-effective amendment thereto became effective and, in the case of the Exchange Offer Registration Statement, as of the date of Consummation of the Exchange Offer, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus contained in such Registration Statement as of its date and, in the case of the opinion dated the date of Consummation of the Exchange Offer, as of the date of Consummation, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Without limiting the foregoing, such counsel may state further that such counsel assumes no responsibility for, and has not independently verified, the accuracy, completeness or fairness of the financial statements, notes and schedules and other financial data included in any Registration Statement contemplated by this Agreement or the related Prospectus; and (3) a customary comfort letter, dated the date of Consummation of the Exchange Offer, or as of the date of effectiveness of the Shelf Registration Statement, as the case may be, from the Issuers' independent accountants, in the customary form and covering matters of the type customarily covered in comfort letters to underwriters in connection with underwritten offerings, and affirming the matters set forth in the comfort letters delivered pursuant to Section 9(g) of the Purchase Agreement; and (B) deliver such other documents and certificates as may be reasonably requested by the selling Holders to evidence compliance with the matters covered in clause (A) above and with any customary conditions contained in any agreement entered into by the Issuers and the Subsidiary Guarantors pursuant to this clause (xi); 13

(xii) prior to any public offering of Transfer Restricted Securities, cooperate with the selling Holders and their counsel in connection with the registration and qualification of the Transfer Restricted Securities under the securities or Blue Sky laws of such jurisdictions as the selling Holders may request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the applicable Registration Statement; provided, however, that neither the Issuers nor any Subsidiary Guarantor shall be required to register or qualify as a foreign corporation where it is not now so qualified or to take any action that would subject it to the service of process in suits or to taxation, other than as to matters and transactions relating to the Registration Statement, in any jurisdiction where it is not now so subject; (xiii) in connection with any sale of Transfer Restricted Securities that will result in such securities no longer being Transfer Restricted Securities, cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and to register such Transfer Restricted Securities in such denominations and such names as the selling Holders may request at least two Business Days prior to such sale of Transfer Restricted Securities; (xiv) use their respective best efforts to cause the disposition of the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Transfer Restricted Securities, subject to the proviso contained in clause (xii) above; (xv) provide a CUSIP number for all Transfer Restricted Securities not later than the effective date of a Registration Statement covering such Transfer Restricted Securities and provide the Trustee under the Indenture with printed certificates for the Transfer Restricted Securities which are in a form eligible for deposit with The Depository Trust Company; (xvi) otherwise use their respective best efforts to comply with all applicable rules and regulations of the Commission, and make generally available to their security holders with regard to any applicable Registration Statement, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) covering a twelve-month period beginning after the effective date of the Registration Statement (as such term is defined in paragraph (c) of Rule 158 under the Act); (xvii) cause the Indenture to be qualified under the TIA not later than the effective date of the first Registration Statement required by this Agreement and, in connection therewith, cooperate with the Trustee and the Holders to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the TIA; and execute and use its best efforts to 14

cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner; and (xviii) provide promptly to each Holder, upon request, each document filed with the Commission pursuant to the requirements of Section 13 or Section 15(d) of the Exchange Act. (d) Restrictions on Holders. Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of the notice referred to in Section 6(c)(iii)(C) or any notice from the Issuers of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof (in each case, a "Suspension Notice"), such Holder will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Registration Statement until (i) such Holder has received copies of the supplemented or amended Prospectus contemplated by Section 6(c)(iv) hereof, or (ii) such Holder is advised in writing by the Issuers that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus (in each case, the "Recommencement Date"). Each Holder receiving a Suspension Notice hereby agrees that it will either (i) destroy any Prospectuses, other than permanent file copies, then in such Holder's possession which have been replaced by the Issuers with more recently dated Prospectuses or (ii) deliver to the Issuers (at the Issuers' expense) all copies, other than permanent file copies, then in such Holder's possession of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of the Suspension Notice. The time period regarding the effectiveness of such Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended by a number of days equal to the number of days in the period from and including the date of delivery of the Suspension Notice to the date of delivery of the Recommencement Date. (e) Effectiveness of Registration Statement. Notwithstanding anything to the contrary contained in this Agreement, the obligation of the Issuers and the Subsidiary Guarantors hereunder to maintain the effectiveness of any Registration Statement and any related Prospectus may be suspended, without default or penalty to the Issuers or the Subsidiary Guarantors, for one or more periods of time as may be required with respect to such Registration Statement if (A) the Board of Directors of the General Partner shall have determined that the offering and sales under the Registration Statement, the filing of such Registration Statement or the maintenance of its effectiveness would require disclosure of or would interfere in any material respect with any material financing, acquisition, merger, offering or other transaction involving the Issuers or the Subsidiary Guarantors or would otherwise require disclosure of nonpublic information that could materially and adversely affect the Issuers or the Subsidiary Guarantors or (B) the Issuers are required by any state or federal securities laws to file an amendment or supplement to such Registration Statement for the purpose of incorporating quarterly or annual information, which is not automatically effective. Further, the Issuers and the Subsidiary Guarantors shall be deemed to have used their respective best efforts to keep any Registration Statement continuously effective if either (A) or (B) above has occurred. 15

Section 7. Registration Expenses. (a) All expenses incident to the Issuers' and the Subsidiary Guarantors' performance of or compliance with this Agreement will be borne by the Issuers, regardless of whether a Registration Statement becomes effective, including without limitation: (i) all registration and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state Blue Sky or securities laws; (iii) all expenses of printing (including printing certificates for the Series B Notes to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Issuers, the Subsidiary Guarantors and the Holders of Transfer Restricted Securities; (v) all application and filing fees in connection with listing the Series B Notes on a national securities exchange or automated quotation system pursuant to the requirements hereof; and (vi) all fees and disbursements of independent certified public accountants of the Issuers and the Subsidiary Guarantors (including the expenses of any special audit and comfort letters required by or incident to such performance). The Issuers will, in any event, bear their and the Subsidiary Guarantors' internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Issuers or the Subsidiary Guarantors. (b) In connection with any Registration Statement required by this Agreement (including, without limitation, the Exchange Offer Registration Statement and the Shelf Registration Statement), the Issuers and the Subsidiary Guarantors will reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities who are tendering Series A Notes in the Exchange Offer and/or selling or reselling Series A Notes or Series B Notes pursuant to the "Plan of Distribution" contained in the Exchange Offer Registration Statement or the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel, who shall be Simpson Thacher & Bartlett, unless another firm shall be chosen by the Holders of a majority in principal amount of the Transfer Restricted Securities for whose benefit such Registration Statement is being prepared. Section 8. Indemnification. (a) The Issuers and the Subsidiary Guarantors agree, jointly and severally, to indemnify and hold harmless each Holder, its directors, officers and each Person, if any, who controls such Holder (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act), from and against any and all losses, claims, damages, liabilities or judgments (including without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action that could give rise to any such losses, claims, damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, preliminary prospectus or Prospectus (or any amendment or supplement thereto) provided by the Issuers to any Holder or any prospective purchaser 16

of Series B Notes or registered Series A Notes, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by an untrue statement or omission or alleged untrue statement or omission that is based upon information relating to any of the Holders furnished in writing to the Issuers by any of the Holders. (b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Issuers and the Subsidiary Guarantors, and their respective directors and officers, and each Person, if any, who controls (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Issuers or the Subsidiary Guarantors, to the same extent as the foregoing indemnity from the Issuers and the Subsidiary Guarantors set forth in Section 8(a) above, but only with reference to information relating to such Holder furnished in writing to the Issuers by such Holder expressly for use in any Registration Statement. In no event shall any Holder, its directors, officers or any Person who controls such Holder be liable or responsible for any amount in excess of the amount by which the total amount received by such Holder with respect to its sale of Transfer Restricted Securities pursuant to a Registration Statement exceeds (i) the amount paid by such Holder for such Transfer Restricted Securities and (ii) the amount of any damages that such Holder, its directors, officers or any Person who controls such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. (c) In case any action shall be commenced involving any Person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the "indemnified party"), the indemnified party shall promptly notify the Person against whom such indemnity may be sought (the "indemnifying person") in writing and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 8(a) and 8(b), a Holder shall not be required to assume the defense of such action pursuant to this Section 8(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Holder). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar or related actions in the same 17

jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by a majority of the Holders, in the case of the parties indemnified pursuant to Section 8(a), and by the Issuers and Subsidiary Guarantors, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action (i) effected with its written consent or (ii) effected without its written consent if the settlement is entered into more than twenty Business Days after the indemnifying party shall have received a request from the indemnified party for reimbursement for the fees and expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party) and, prior to the date of such settlement, the indemnifying party shall have failed to comply with such reimbursement request. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or could have been the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of the indemnified party. (d) To the extent that the indemnification provided for in this Section 8 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Subsidiary Guarantors, on the one hand, and the Holders, on the other hand, from their sale of Transfer Restricted Securities or (ii) if the allocation provided by clause 8(d)(i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the Issuers and the Subsidiary Guarantors, on the one hand, and of the Holder, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative fault of the Issuers and the Subsidiary Guarantors, on the one hand, and of the Holder, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuers or such Subsidiary Guarantor, on the one hand, or by the Holder, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Issuers, the Subsidiary Guarantors and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro 18

rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such indemnified party in connection with investigating or defending any matter, including any action that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 8, no Holder, its directors, its officers or any Person, if any, who controls such Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total received by such Holder with respect to the sale of Transfer Restricted Securities pursuant to a Registration Statement exceeds (i) the amount paid by such Holder for such Transfer Restricted Securities and (ii) the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders' obligations to contribute pursuant to this Section 8(d) are several in proportion to the respective principal amount of Transfer Restricted Securities held by each Holder hereunder and not joint. Section 9. Rule 144A and Rule 144. The Issuers and each Subsidiary Guarantor agree with each Holder, for so long as any Transfer Restricted Securities remain outstanding and during any period in which the Issuers or such Subsidiary Guarantor (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make available, upon request of any Holder, to such Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities designated by such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of the Exchange Act, to make all filings required thereby in a timely manner in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144. Section 10. Miscellaneous. (a) Remedies. The Issuers and the Subsidiary Guarantors acknowledge and agree that any failure by the Issuers and/or the Subsidiary Guarantors to comply with their respective obligations under Sections 3 and 4 hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Issuers' and the Subsidiary Guarantors' obligations under Sections 3 and 4 hereof. The Issuers and the Subsidiary Guarantors further agree to waive the defense in any action for specific performance that a remedy at law would be adequate. (b) No Inconsistent Agreements. Neither the Issuers nor any Subsidiary Guarantor will, on or after the date of this Agreement, enter into any agreement with 19

respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Neither the Issuers nor any Subsidiary Guarantor have previously entered into any agreement granting any registration rights with respect to its securities to any Person other than the registration rights (i) of El Paso Energy Partners Company and its affiliates in Section 6.14 of the Partnership Agreement, (ii) of EPEC Deepwater Gathering Company ("EPEC") and its successors pursuant to a registration rights agreement between EPEC and the Partnership which was executed in connection with the acquisition by the Partnership of an additional interest in Viosca Knoll Gathering Company, (iii) of Crystal Gas Storage, Inc. ("Crystal") pursuant to the registration rights agreement dated as of August 28, 2000 between Crystal and the Partnership which was executed in connection with the acquisition by the Partnership of the Crystal storage facilities, (iv) granted under the Partnership Credit Facility (as amended, restated and otherwise supplemented through the date hereof) and related agreements, (v) of the General Partner and its affiliates in Section 6.14 of the Partnership Agreement and in the registration rights agreement executed in connection with the November 2002 acquisition by the Partnership of the San Juan assets and (vi) granted pursuant to this Agreement. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Issuers' and the Subsidiary Guarantors' securities under any agreement in effect on the date hereof.

The terms and provisions contained in the Notes (including the Guarantees) shall constitute, and are hereby expressly made, a part of this Indenture and the Partnership, El Paso Finance, the Subsidiary Guarantors, and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. Notes issued in global form shall be substantially in the form of Exhibit A attached hereto (including the Global Note Legend and the "Schedule of Exchanges in the Global Note" attached thereto). Notes issued in definitive form shall be substantially in the form of Exhibit A attached hereto (but without the Global Note Legend, the phrase identified in footnote 1 thereto and without the "Schedule of Exchanges of Interests in the Global Note" attached thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. SECTION 2.02. EXECUTION AND AUTHENTICATION. One Officer of the Partnership and one Officer of El Paso Finance shall sign the Notes for the Partnership and El Paso Finance, respectively, by manual or facsimile signature. The seal of the Partnership and El Paso Finance shall be reproduced on the Notes and may be in facsimile form. If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid. A Note shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 30

The Trustee shall, upon a written order of the Partnership and El Paso Finance signed by one Officer of the Partnership and one Officer of El Paso Finance, authenticate (i) $300,000,000 aggregate principal amount of Notes, with the Guarantees endorsed thereon, for original issue on the Issue Date and (ii) any amount of additional Notes specified by the Issuers, in each case, upon a written order of the Partnership and El Paso Finance signed by one Officer of the Partnership and one Officer of El Paso Finance. Such order shall specify (a) the amount of the Notes of each series to be authenticated and the date of original issue thereof, and (b) whether the Notes are Series A Notes or Exchange Notes. The aggregate principal amount of Notes of any series outstanding at any time may not exceed the aggregate principal amount of Notes of such series authorized for issuance by the Issuers pursuant to one or more written orders of the Issuers, except as provided in Section 2.07 hereof. Subject to the foregoing, the aggregate principal amount of Notes of any series that may be issued under this Indenture shall not be limited. The Trustee may appoint an authenticating agent acceptable to the Issuers to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of either of the Issuers. SECTION 2.03. REGISTRAR AND PAYING AGENT. The Partnership, El Paso Finance and the Subsidiary Guarantors shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange ("Registrar") and an office or agency in the State of New York where Notes may be presented for payment ("Paying Agent"). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The term "Registrar" includes any co-registrar and the term "Paying Agent" includes any additional paying agent. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The Issuers shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Partnership, El Paso Finance or any of the Subsidiary Guarantors may act as Paying Agent or Registrar. The Issuers initially appoint The Depository Trust Company ("DTC") to act as Depositary with respect to the Global Notes. The Issuers initially appoint the Trustee to act as the Registrar and Paying Agent and to act as Note Custodian with respect to the Global Notes. SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST. The Issuers shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest or Liquidated Damages, if any, on the Notes, and will notify the Trustee of any default by the 31

Partnership, El Paso Finance or the Subsidiary Guarantors in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than an Issuer or a Subsidiary Guarantor) shall have no further liability for the money. If an Issuer or a Subsidiary Guarantor acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Partnership or El Paso Finance, the Trustee shall serve as Paying Agent for the Notes. SECTION 2.05. HOLDER LISTS. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Issuers shall otherwise comply with TIA Section 312(a). SECTION 2.06. TRANSFER AND EXCHANGE. (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes may be exchanged by the Issuers for Certificated Notes if (i) the Issuers deliver to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuers within 90 days after the date of such notice from the Depositary, (ii) the Issuers in their sole discretion determine that the Global Notes (in whole but not in part) should be exchanged for Certificated Notes and deliver a written notice to such effect to the Trustee; provided that in no event shall the Regulation S Global Note be exchanged by the Issuers for Certificated Notes prior to (x) the expiration of the Distribution Compliance Period and (y) the receipt by the Registrar of any certificates required pursuant to Rule 903 under the Securities Act, or (iii) if a Default or an Event of Default occurs and is continuing. Whenever a Global Note is exchanged as a whole for one or more Certificated Notes, it shall be surrendered by the Holder thereof to the Trustee for cancellation. Whenever a Global Note is exchanged in part for one or more Certificated Notes, it shall be surrendered by the Holder thereof to the Trustee and the Trustee shall make the appropriate notations to the Schedule of Exchanges of Interests in the Global Notes attached thereto pursuant to Section 2.01 hereof. All Certificated Notes issued in exchange for a Global Note or any portion thereof shall be registered in such names, and delivered, as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for 32

another Note other than as provided in this Section 2.06(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof. (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes shall be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also shall require compliance with either subparagraph (i) or (ii) below, as applicable, as well as one or more of the other following subparagraphs as applicable: (i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend; provided, however, that prior to the expiration of the Distribution Compliance Period transfers of beneficial interests in the Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted Global Note may be transferred only to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(i). (ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests (other than a transfer of a beneficial interest in a Global Note to a Person who takes delivery thereof in the form of a beneficial interest in the same Global Note), the transferor of such beneficial interest must deliver to the Registrar either (A) (i) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged and (ii) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase or (B) (i) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Certificated Note in an amount equal to the beneficial interest to be transferred or exchanged and (ii) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Certificated Note shall be registered to effect the transfer or exchange referred to in (i) above; provided that in no event shall Certificated Notes be issued upon the transfer or exchange of beneficial interests in the Regulation S Global Note prior to (x) the expiration of the Distribution Compliance Period and (y) the receipt by the Registrar of any certificates required pursuant to Rule 903 under the Securities Act. Upon an Exchange Offer by the Issuers in accordance 33

with Section 2.06(f) hereof, the requirements of this Section 2.06(b)(ii) shall be deemed to have been satisfied upon receipt by the Registrar of the instructions contained in the Letter of Transmittal delivered by the Holder of such beneficial interests in the Restricted Global Notes.

(iii) The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because an Issuer or an Affiliate of an Issuer holds the Note. If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest and Liquidated Damages, if applicable, on it cease to accrue. If the Paying Agent (other than an Issuer or a Subsidiary or an Affiliate of an Issuer) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest (and Liquidated Damages, if any). SECTION 2.09. TREASURY NOTES.

SECTION 2.10. TEMPORARY NOTES. Until Certificated Notes are ready for delivery, the Issuers may prepare and the Trustee shall authenticate temporary Notes (accompanied by a notation of the Guarantees duly endorsed by the Subsidiary Guarantors) upon a written order of the Issuers signed by one Officer of the Partnership and one Officer of El Paso Finance. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuers consider appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate definitive Notes (accompanied 47

by a notation of the Guarantees duly endorsed by the Subsidiary Guarantors) in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. SECTION 2.11. CANCELLATION. Either of the Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment.

The Issuers may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. SECTION 2.12. DEFAULTED INTEREST. If any of the Partnership, El Paso Finance or any Subsidiary Guarantor defaults in a payment of interest on the Notes, it or they (to the extent of their obligations under the Guarantees) shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuers shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuers shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. SECTION 2.13. CUSIP NUMBERS. The Issuers in issuing the Notes may use "CUSIP" numbers (if then generally in use), and, if they do so, the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuers will promptly notify the Trustee of any change in the "CUSIP" numbers. ARTICLE 3 REDEMPTION AND PREPAYMENT SECTION 3.01. NOTICES TO TRUSTEE.

No Notes of $1,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. Notices of redemption may not be conditional. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest and Liquidated Damages, if applicable, cease to accrue on Notes or portions of them called for redemption unless the Issuers default in making such redemption payment. SECTION 3.03. NOTICE OF REDEMPTION. At least 30 days but not more than 60 days before a redemption date, the Issuers shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address.

At the Issuers' request, the Trustee shall give the notice of redemption in the Issuers' names and at their expense; provided, however, that the Issuers shall have delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter period is otherwise acceptable to the Trustee), an Officers' Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION. Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. SECTION 3.05. DEPOSIT OF REDEMPTION PRICE. Not later than 11:00 a.m., New York City time, on the redemption date, the Issuers shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest and Liquidated Damages, if applicable, on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption price of, and accrued interest and Liquidated Damages, if applicable, on, all Notes to be redeemed. If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption date, interest and Liquidated Damages, if applicable, shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest (and Liquidated Damages, if any) shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuers to comply with the preceding paragraph, interest (and Liquidated Damages, if any) shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 50

SECTION 3.06. NOTES REDEEMED IN PART. Upon surrender of a Note that is redeemed in part, the Issuers shall issue and, upon the Issuers' written request, the Trustee shall authenticate for the Holder at the expense of the Issuers a new Note (accompanied by a notation of the Guarantees duly endorsed by the Subsidiary Guarantors) equal in principal amount to the unredeemed portion of the Note surrendered.

(b) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 4.19(a) shall be accompanied by a written statement of the Issuers' independent public accountants (who shall be a firm of established national reputation) that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Issuers have violated any provisions of Article 4 or Article 5 hereof (except that such written statement need not address the Issuers' and Subsidiary Guarantors' compliance with Sections 4.02, 4.05, 4.06 or 4.13 hereof) or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation. (c) Each of the Issuers shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer of the Partnership, the General Partner or El Paso Finance becoming aware of any Default or Event of Default, an Officers' Certificate specifying such Default or Event of Default and what action the Issuers are taking or propose to take with respect thereto. SECTION 4.04. TAXES. The Issuers shall pay, and shall cause each of its Restricted Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. 55

SECTION 4.05. STAY, EXTENSION AND USURY LAWS. Each of the Issuers and the Subsidiary Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the Issuers and the Subsidiary Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. SECTION 4.06. CHANGE OF CONTROL. (a) If a Change of Control occurs, each Holder of Notes shall have the right to require the Issuers to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of that Holder's Notes pursuant to the offer described below (the "Change of Control Offer"). In the Change of Control Offer, the Issuers shall offer a "Change of Control Payment" in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest thereon, if any, and Liquidated Damages, if any, to the date of purchase (the "Change of Control Payment"). Within 30 days following any Change of Control, the Issuers shall mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the Change of Control Payment Date specified in such notice, pursuant to the procedures required by this Indenture and described in such notice. If the Change of Control Payment Date is on or after a record date and on or before the related Interest Payment Date, any accrued and unpaid interest and Liquidated Damages (to the extent involving interest that is due and payable on such Interest Payment Date), if any, shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest (or Liquidated Damages, if any) (to the extent involving interest that is due and payable on such Interest Payment Date) shall be payable to Holders who validly tender Notes pursuant to the Change of Control Offer. The Issuers shall comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. (b) Within 30 days following any Change of Control, the Issuers shall mail by first class mail, a notice to each Holder, with a copy of such notice to the Trustee. The notice, which shall govern the terms of the Change of Control Offer, shall state, among other things: (i) that a Change of Control has occurred and a Change of Control Offer is being made as provided for herein, and that, although Holders are not required to tender their Notes, all Notes that are validly tendered shall be accepted for payment; 56

(ii) the Change of Control Payment and the Change of Control Payment Date, which will be no earlier than 30 days and no later than 60 days after the date such notice is mailed; (iii) that any Note accepted for payment pursuant to the Change of Control Offer (and duly paid for on the Change of Control Payment Date) shall cease to accrue interest and Liquidated Damages, if applicable, after the Change of Control Payment Date; (iv) that any Notes (or portions thereof) not validly tendered shall continue to accrue interest and Liquidated Damages, if applicable; (v) that any Holder electing to have a Note purchased pursuant to any Change of Control Offer shall be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, or transfer by book-entry transfer, to the Issuers, a depositary, if appointed by the Issuers, or a Paying Agent at the address specified in the notice at least one (1) Business Day before the Change of Control Payment Date; (vi) that Holders shall be entitled to withdraw their election if the Issuers, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Change of Control Offer, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; and (vii) the instructions and any other information necessary to enable Holders to tender their Notes (or portions thereof) and have such Notes (or portions thereof) purchased pursuant to the Change of Control Offer. (c) Subject to Section 4.06(f), on the Change of Control Payment Date, the Issuers shall, to the extent lawful: (i) accept for payment all Notes or portions thereof properly tendered and not withdrawn pursuant to the Change of Control Offer; (ii) deposit by 11:00 a.m., New York Time with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered; and 57

(iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Issuers. (d) The Paying Agent shall promptly mail to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $1,000 or an integral multiple thereof. The Issuers shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. (e) Upon surrender and cancellation of a Certificated Note that is purchased in part pursuant to the Change of Control Offer, the Issuers shall promptly issue and the Trustee shall authenticate and mail (or cause to be transferred by book entry) to the surrendering Holder of such Certificated Note, a new Certificated Note equal in principal amount to the unpurchased portion of such surrendered Certificated Note; provided that each such new Certificated Note shall be in principal amount of $1,000 or an integral multiple thereof. (f) Prior to complying with any of the provisions of this Section 4.06, but in any event within 90 days following a Change of Control, the Issuers shall either repay all outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing outstanding Senior Debt to permit the repurchase of Notes required by this covenant. (g) The provisions described in this Section 4.06 require the Issuers to make a Change of Control Offer following a Change of Control shall be applicable regardless of whether or not any other provisions of this Indenture are applicable. (h) Notwithstanding the other provisions of this Section 4.06, the Issuers shall not be required to make a Change of Control Offer upon a Change of Control, and a Holder will not have the right to require that the Issuers repurchase any Notes pursuant to a Change of Control Offer, if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuers and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. SECTION 4.07. ASSET SALES. (a) The Issuers shall not, and shall not permit any Restricted Subsidiary of the Partnership to, consummate an Asset Sale unless: (i) such Issuer (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; (ii) such fair market value is determined by (a) an executive officer of the Partnership if the value is less than $10.0 million, as evidenced by an Officers' 58

Certificate delivered to the Trustee or (b) the Board of Directors of the General Partner if the value is $10.0 million or more, as evidenced by a resolution of such Board of Directors of the General Partner; and (iii) at least 75% of the Net Proceeds received by such Issuer or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this clause (iii), each of the following shall be deemed to be cash: (A) any liabilities (as shown on such Issuer's or such Restricted Subsidiary's most recent balance sheet) of the Issuers or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases such Issuer or such Restricted Subsidiary from further liability; and (B) any securities, notes or other obligations received by such Issuer or any such Restricted Subsidiary from such transferee that are within 90 days after the Asset Sale (subject to ordinary settlement periods) converted by such Issuer or such Restricted Subsidiary into cash (to the extent of the cash received in that conversion). (b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Partnership or a Restricted Subsidiary may apply (or enter into a definitive agreement for such application, provided that such capital expenditure or purchase is closed within 90 days after the end of such 360-day period) such Net Proceeds at its option: (i) to repay Senior Debt of the Partnership and/or its Restricted Subsidiaries (or to make an offer to repurchase or redeem any such Senior Debt, provided that such repurchase or redemption closes within 45 days after the end of such 360-day period) with a permanent reduction in availability for any revolving credit Indebtedness; (ii) to make a capital expenditure in a Permitted Business; (iii) to acquire other long-term tangible assets that are used or useful in a Permitted Business; or (iv) to invest in any other Permitted Business Investment or any other Permitted Investments other than Investments in Cash Equivalents, Interest Swaps or Currency Agreements. Pending the final application of any such Net Proceeds, the Partnership or a Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture. (c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.07(b) above will constitute "Excess Proceeds". When the aggregate 59

amount of Excess Proceeds exceeds $10 million, the Issuers will make a pro rata offer (an "Asset Sale Offer") to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest (including any Liquidated Damages in the case of the Notes), if any, and premium, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Partnership may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture, including, without limitation, the repurchase or redemption of Indebtedness of the Issuers or any Subsidiary Guarantor that is subordinated to the Notes or, in the case of any Subsidiary Guarantor, the Guarantee of such Subsidiary Guarantor. If the aggregate principal amount of Notes tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds allocated for repurchases of Notes pursuant to the Asset Sale Offer for Notes, the Trustee shall select the Notes to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. (d) Notwithstanding the definition of the term "Asset Sale" in Section 1.01 hereof, the following transactions shall not constitute an Asset Sale for purposes of this Indenture: (i) any transaction whereby assets or properties (including (a) ownership interests in any Subsidiary or Joint Venture and (b) in the case of an exchange or contribution for tangible assets, up to 25% in the form of cash, Cash Equivalents, accounts receivable or other current assets) owned by the Partnership or a Restricted Subsidiary of the Partnership are exchanged or contributed for the Equity Interests of a Joint Venture or Unrestricted Subsidiary in a transaction that satisfies the requirements of a Permitted Business Investment or for other assets (not more than 25% of which consists of cash, Cash Equivalents, accounts receivables or other current assets) or properties (including interests in any Subsidiary or Joint Venture) so long as (i) the fair market value of the assets or properties (if other than a Permitted Business Investment) received are substantially equivalent to the fair market value of the assets or properties given up, and (ii) any cash received in such exchange or contribution by the Partnership or any Restricted Subsidiary of the Partnership is applied in accordance with the foregoing provisions of this Section 4.07; (ii) any sale, transfer or other disposition of cash or Cash Equivalents; (iii) any sale, transfer or other disposition of Restricted Investments; and (iv) any sale, transfer or other disposition of interests in oil and gas leaseholds (including, without limitation, by abandonment, farm-ins, farm-outs, leases, swaps and subleases), hydrocarbons and other mineral products in the ordinary course of business of the oil and gas operations conducted by the 60

Partnership or any Restricted Subsidiary of the Partnership, which sale, transfer or other disposition is made by the Partnership or any such Restricted Subsidiary. SECTION 4.08. RESTRICTED PAYMENTS. (a) The Issuers shall not, and shall not permit any of their Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make any other payment or distribution on account of the Equity Interests of the Partnership or any of its Restricted Subsidiaries (including, without limitation, any payment in connection with any merger or consolidation involving the Partnership or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Equity Interests of the Partnership or of any of its Restricted Subsidiaries in their capacity as such (other than dividends or distributions payable in Equity Interests of the Partnership (other than Disqualified Equity) and other than distributions or dividends payable to the Partnership or a Restricted Subsidiary of the Partnership). (ii) except to the extent permitted in clause (iv) below, purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving an Issuer) any Equity Interests of the Partnership or of any of its Restricted Subsidiaries (other than any such Equity Interests owned by the Partnership or any of its Restricted Subsidiaries); (iii) except to the extent permitted in clause (iv) below, make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is pari passu with or subordinated to the Notes or the Guarantees (other than the Notes or the Guarantees), except (a) a payment of interest or principal at the Stated Maturity thereof, (b) a purchase, redemption, acquisition or retirement required to be made pursuant to the terms of such Indebtedness (including pursuant to an asset sale or change of control provision) and (c) any such Indebtedness of the Partnership or any Restricted Subsidiary owned by the Partnership or a Restricted Subsidiary; (iv) make any Investment other than a Permitted Investment or a Permitted Business Investment (all such payments and other actions set forth in clauses (i) through (iv) above being collectively referred to as "Restricted Payments"), unless, at the time of and after giving effect to such Restricted Payment, no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof and either: (A) if the Fixed Charge Coverage Ratio for the Partnership's four most recent fiscal quarters for which internal financial statements are available is not less than 2.0 to 1.0, such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Partnership and its Restricted 61

Subsidiaries during the quarter in which such Restricted Payment is made, is less than the sum, without duplication, of (a) Available Cash constituting Cash from Operations as of the end of the immediately preceding quarter, plus (b) the aggregate net cash proceeds of any (i) substantially concurrent capital contribution to the Partnership from any Person (other than a Restricted Subsidiary of the Partnership) after the Issue Date, (ii) substantially concurrent issuance and sale after the Issue Date of Equity Interests (other than Disqualified Equity) of the Partnership or from the issuance or sale after the Issue Date of convertible or exchangeable Disqualified Equity or convertible or exchangeable debt securities of the Partnership that have been converted into or exchanged for such Equity Interests (other than Disqualified Equity), (iii) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or Cash Equivalents or otherwise liquidated or repaid for cash or Cash Equivalents, the lesser of the refund of capital or similar payment made in cash or Cash Equivalents with respect to such Restricted Investment (less the cost of such disposition, if any) and the initial amount of such Restricted Investment (other than to a Restricted Subsidiary of the Partnership), plus (c) the net reduction in Investments in Restricted Investments resulting from dividends, repayments of loans or advances, or other transfers of assets in each case to the Partnership or any of its Restricted Subsidiaries from any Person (including, without limitation, Unrestricted Subsidiaries) or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries to the extent such amounts have not been included in Available Cash constituting Cash from Operations for any quarter commencing on or after the Issue Date (items (b) and (c) being referred to as "Incremental Funds"), minus (d) the aggregate amount of Incremental Funds previously expended pursuant to this clause (A) or clause (B) below; or (B) if the Fixed Charge Coverage Ratio for the Partnership's four most recent fiscal quarters for which internal financial statements are available is less than 2.0 to 1.0, such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Partnership and its Restricted Subsidiaries during the quarter in which such Restricted Payment is made, is less than the sum, without duplication, of (a) $60.0 million less the aggregate amount of all Restricted Payments made by the Partnership and its Restricted Subsidiaries pursuant to this clause (B)(a) during the period ending on the last day of the fiscal quarter of the Partnership immediately preceding the date of such Restricted Payment and beginning on the Issue Date, plus (b) Incremental Funds to the extent not previously expended pursuant to this clause (B) or clause (A) above. For purposes of clauses (A) and (B) above, the term "substantially concurrent" means that either (x) the offering was consummated within 120 days of the date of determination or (y) the offering was consummated within 24 months of the date of determination and the proceeds therefrom were used for the purposes expressly stated in the documents related thereto and may be traced to such use by segregating, separating or otherwise specifically identifying the movement of such proceeds. 62

(b) So long as no Default has occurred and is continuing or would be caused thereby, the preceding provisions of this Section 4.08 shall not prohibit: (i) the payment by the Partnership or any of its Restricted Subsidiaries of any distribution or dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of this Indenture; (ii) the redemption, repurchase, retirement, defeasance or other acquisition of any pari passu or subordinated Indebtedness of the Partnership or any of its Restricted Subsidiaries or of any Equity Interests of the Partnership or any of its Restricted Subsidiaries in exchange for, or out of the net cash proceeds of, a substantially concurrent (a) capital contribution to the Partnership or such Restricted Subsidiary from any Person (other than the Partnership or another Restricted Subsidiary) or (b) sale (a sale will be deemed substantially concurrent if such redemption, repurchase, retirement, defeasance or acquisition occurs not more than 120 days after such sale) (other than to a Restricted Subsidiary of the Partnership) of (i) Equity Interests (other than Disqualified Equity) of the Partnership or such Restricted Subsidiary or (ii) Indebtedness that is subordinated to the Notes or the Guarantees, provided that such new subordinated Indebtedness with respect to the redemption, repurchase, retirement, defeasance or other acquisition of pari passu or subordinated Indebtedness (W) is subordinated to the same extent as such refinanced subordinated Indebtedness, (X) has a Weighted Average Life to Maturity of at least the remaining Weighted Average Life to Maturity of the refinanced subordinated Indebtedness, (Y) is for the same principal amount as either such refinanced subordinated Indebtedness plus original issue discount to the extent not reflected therein or the redemption or purchase price of such Equity Interests (plus reasonable expenses of refinancing and any premiums paid on such refinanced subordinated Indebtedness) and (Z) is incurred by the Partnership or the Restricted Subsidiary that is the obligor on the Indebtedness so refinanced or the issuer of the Equity Interests so redeemed, repurchased or retired; provided, however, that the amount of any net cash proceeds that are utilized for any such redemption, repurchase or other acquisition or retirement shall be excluded or deducted from the calculation of Available Cash and Incremental Funds; (iii) the defeasance, redemption, repurchase or other acquisition of pari passu or subordinated Indebtedness of the Partnership or any Restricted Subsidiary with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; (iv) the payment of any distribution or dividend by a Restricted Subsidiary to the Partnership or to the holders of the Equity Interests (other than Disqualified Equity) of such Restricted Subsidiary on a pro rata basis; (v) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Partnership or any of its Restricted 63

Subsidiaries held by any member of the General Partner's or the Partnership's or any Restricted Subsidiary's management pursuant to any management equity subscription agreement or stock option agreement or to satisfy obligations under any Equity Interests appreciation rights or option plan or similar arrangement; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $5.0 million in any 12-month period; and (vi) any payment by the Partnership pursuant to section 3.1(b) of the Management Agreement to compensate for certain tax liabilities resulting from certain allocated income. In computing the amount of Restricted Payments made for purposes of Section 4.08(a), Restricted Payments made under clauses (i) (but only if the declaration of such dividend or other distribution has not been counted in a prior period) and, to the extent of amounts paid to holders other than the Partnership or any of its Restricted Subsidiaries, (iv) of this Section 4.08(b) shall be included, and Restricted Payments made under clauses (ii), (iii), (v) and (vi) and, except to the extent noted above, (iv) of this Section 4.08(b) shall not be included. The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Partnership or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this covenant shall be determined by the Board of Directors of the General Partner whose resolution with respect thereto shall be delivered to the Trustee. SECTION 4.09. INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF DISQUALIFIED EQUITY (a) The Partnership shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt), and the Partnership will not issue any Disqualified Equity and will not permit any of its Restricted Subsidiaries to issue any Disqualified Equity; provided, however, that the Partnership and any Restricted Subsidiary may incur Indebtedness (including Acquired Debt), and the Partnership and the Restricted Subsidiaries may issue Disqualified Equity, if the Fixed Charge Coverage Ratio for the Partnership's most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Equity is issued would have been at least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred, or the Disqualified Equity had been issued, at the beginning of such four-quarter period. (b) Notwithstanding the prohibitions of Section 4.09(a), so long as no Default or Event of Default shall have occurred and be continuing or would be caused thereby, the Partnership and its Restricted Subsidiaries may incur any of the following items of Indebtedness (collectively, "Permitted Debt"): 64

(i) the incurrence by the Partnership and any of its Restricted Subsidiaries of the Indebtedness under Credit Facilities and the guarantees thereof; provided that the aggregate principal amount of all Indebtedness of the Partnership and the Restricted Subsidiaries outstanding under all Credit Facilities after giving effect to such incurrence does not exceed $1.2 billion less the aggregate amount of all repayments of Indebtedness under a Credit Facility that have been made by the Partnership or any of its Restricted Subsidiaries with Net Proceeds from Asset Sales to the extent such repayments constitute a permanent reduction of commitments under such Credit Facility; (ii) the incurrence by the Partnership and its Restricted Subsidiaries of Existing Indebtedness; (iii) the incurrence by the Partnership and the Subsidiary Guarantors of Indebtedness represented by the Notes and the Guarantees and the related Obligations; (iv) the incurrence by the Partnership or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Partnership or such Restricted Subsidiary, in an aggregate principal amount not to exceed $20.0 million at any time outstanding; (v) the incurrence by the Partnership or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace, Indebtedness (other than intercompany Indebtedness) that was not incurred in violation of this Indenture; (vi) the incurrence by the Partnership or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Partnership and any of its Restricted Subsidiaries; provided, however, that: (A) if the Partnership or any Subsidiary Guarantor is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, in the case of the Partnership, or the Guarantee of such Subsidiary Guarantor, in the case of a Subsidiary Guarantor; and (B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Partnership or a Restricted Subsidiary thereof and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Partnership or a Restricted Subsidiary thereof, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Partnership 65

or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (vi); (vii) the incurrence by the Partnership or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging foreign currency exchange rate risk of the Partnership or any Restricted Subsidiary or interest rate risk with respect to any floating rate Indebtedness of the Partnership or any Restricted Subsidiary that is permitted by the terms of this Indenture to be outstanding or commodities pricing risks of the Partnership or any Restricted Subsidiary in respect of hydrocarbon production from properties in which the Partnership or any of its Restricted Subsidiaries owns an interest; (viii) the guarantee by the Partnership or any of its Restricted Subsidiaries of Indebtedness of the Partnership or a Restricted Subsidiary of the Partnership that was permitted to be incurred by another provision of this covenant; (ix) bid, performance, surety and appeal bonds incurred in the ordinary course of business, including guarantees and standby letters of credit supporting such obligations, to the extent not drawn; (x) the incurrence by the Partnership or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (x), not to exceed $20.0 million; (xi) the incurrence by the Partnership's Unrestricted Subsidiaries of Non-Recourse Debt; provided, however, that if any such Indebtedness ceases to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Partnership that was not permitted by this clause (xi); (xii) the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Equity, in the form of additional shares of the same class of Disqualified Equity, provided, in each such case, that the amount thereof is included in Fixed Charges of the Partnership as so accrued, accredited or amortized; and (xiii) Indebtedness incurred by the Partnership or any of its Restricted Subsidiaries arising from agreements or their respective bylaws providing for indemnification, adjustment of purchase price or similar obligations. (c) For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in paragraphs (b)(i) through (b)(xiii) above, or is entitled to be incurred pursuant to Section 4.09(a), the Partnership shall be permitted to classify such item of 66

Indebtedness on the date of its incurrence in any manner that complies with this Section 4.09. An item of Indebtedness may be divided and classified in one or more of the types of Permitted Indebtedness. SECTION 4.10. ANTI-LAYERING. The Issuers shall not incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to any Senior Debt of either of the Issuers and senior in any respect in right of payment to the Notes. No Subsidiary Guarantor shall incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to any Senior Debt of such Subsidiary Guarantor and senior in any respect in right of payment to such Subsidiary Guarantor's Guarantee. SECTION 4.11. LIENS. The Partnership shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind securing Indebtedness, Attributable Debt or trade payables on any asset now owned or hereafter acquired, except Permitted Liens, without making effective provision whereby all Obligations due under the Notes and this Indenture or any Guarantee, as applicable, will be secured by a Lien equally and ratably with any and all Obligations thereby secured for so long as any such Obligations shall be so secured. SECTION 4.12. DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES. The Partnership shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to: (a) pay dividends or make any other distributions on its Equity Interests to the Partnership or any of the Partnership's Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Partnership or any of the other Restricted Subsidiaries; (b) make loans or advances to or make other investments in the Partnership or any of the other Restricted Subsidiaries; or (c) transfer any of its properties or assets to the Partnership or any of the other Restricted Subsidiaries.

SECTION 4.13. TRANSACTIONS WITH AFFILIATES (a) The Partnership shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each, an "Affiliate Transaction"), unless: (i) such Affiliate Transaction is on terms that are no less favorable to the Partnership or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Partnership or such Restricted Subsidiary with an unrelated Person; and (ii) the Partnership delivers to the Trustee: (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million but less than or equal to $25.0 million, an Officers' 69

Even though a particular Affiliate Transaction or series of Affiliate Transactions may be covered by two or more of clauses (a) 70

through (d) above, the compliance with any one of such applicable clauses shall be satisfactory. (b) The following items shall not be deemed to be Affiliate Transactions and, therefore, shall not be subject to the provisions of Section 4.13(a): (i) transactions pursuant to the Management Agreement as in effect on the date hereof; (ii) any employment, equity option or equity appreciation agreement or plan entered into by the Partnership or any of its Restricted Subsidiaries in the ordinary course of business and, as applicable, consistent with the past practice of the Partnership or such Restricted Subsidiary; (iii) transactions between or among the Partnership and/or its Restricted Subsidiaries; (iv) Restricted Payments that are permitted by Section 4.08; (v) transactions effected in accordance with the terms of agreements as in effect on the Issue Date; (vi) customary compensation, indemnification and other benefits made available to officers, directors or employees of the Partnership or a Restricted Subsidiary, including reimbursement or advancement of out-of-pocket expenses and provisions of officers' and directors' liability insurance; and (vii) loans to officers and employees made in the ordinary course of business in an aggregate amount not to exceed $1.0 million at any one time outstanding. SECTION 4.14. ADDITIONAL SUBSIDIARY GUARANTEES. If the Partnership or any of its Restricted Subsidiaries acquires or creates another Restricted Subsidiary after the Issue Date that guarantees any Indebtedness of either of the Issuers, then that newly acquired or created Restricted Subsidiary must become a Subsidiary Guarantor and execute a supplemental indenture satisfactory to the Trustee and deliver an Opinion of Counsel to the Trustee within 10 Business Days of the date on which it was acquired or created. If a Restricted Subsidiary that is not then a Subsidiary Guarantor guarantees Indebtedness of either of the Issuers or any other Restricted Subsidiary, such Restricted Subsidiary shall execute and deliver a Guarantee. The Partnership will not permit any of its Restricted Subsidiaries, directly or indirectly, to guarantee or pledge any assets to secure the payment of any other Indebtedness of either Issuer unless such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture providing for the guarantee of the payment of the Notes by such Restricted Subsidiary, which Guarantee shall be senior to or pari passu with such Restricted Subsidiary's guarantee of or pledge to secure such other Indebtedness, unless such other Indebtedness is Senior Debt, in which case the Guarantee of the Notes may be subordinated to the guarantee of such Senior Debt to the same extent as the Notes 71

are subordinated to such Senior Debt. Notwithstanding the foregoing, any Guarantee of a Restricted Subsidiary that was incurred pursuant to this paragraph shall provide by its terms that it shall be automatically and unconditionally released upon the release or discharge of the guarantee which resulted in the creation of such Restricted Subsidiary's Subsidiary Guarantee, except a discharge or release by, or as a result of payment under, such guarantee. SECTION 4.15. DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES. The General Partner may designate any Restricted Subsidiary of the Partnership to be an Unrestricted Subsidiary if that designation would not cause a Default or Event of Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, all outstanding Investments owned by the Partnership and its Restricted Subsidiaries in the Subsidiary so designated will be deemed to be an Investment made as of the time of such designation and will reduce the amount available for Restricted Payments under Section 4.08(a), for Permitted Investments or for Permitted Business Investments, as applicable. All such outstanding Investments will be valued at their fair market value, as determined by the Board of Directors of the General Partner, at the time of such designation. That designation will only be permitted if such Restricted Payment, Permitted Investments or Permitted Business Investments would be permitted under this Indenture at that time and such Restricted Subsidiary otherwise complies with the definition of an Unrestricted Subsidiary. All Subsidiaries of such an Unrestricted Subsidiary shall be also thereafter constitute Unrestricted Subsidiaries. A Subsidiary may not be designated as an Unrestricted Subsidiary unless at the time of such designation, (x) it has no Indebtedness other than Non-Recourse Debt; (y) no portion of the Indebtedness or any other obligation of such Subsidiary (whether contingent or otherwise and whether pursuant to the terms of such Indebtedness or the terms governing the organization and operation of such Subsidiary or by law) (A) is guaranteed by the Partnership or any of its other Restricted Subsidiaries, except as such Indebtedness is permitted by Sections 4.08 and 4.09, (B) is recourse to or obligates the Partnership or any of its Restricted Subsidiaries in any way (including any "claw-back", "keep-well' or "make-well" agreements or other agreements, arrangements or understandings to maintain the financial performance or results of operations of such Subsidiary, except as such Indebtedness or Investment is permitted by Sections 4.08 and 4.09), or (C) subjects any property or assets of the Partnership or any of its other Restricted Subsidiaries, directly or indirectly, contingently or otherwise, to the satisfaction thereof; and (z) no Equity Interests of a Restricted Subsidiary are held by such Subsidiary, directly or indirectly. Upon the designation of a Restricted Subsidiary that is a Subsidiary Guarantor as an Unrestricted Subsidiary, the Guarantee of such entity shall be released and the Trustee shall be authorized to take such actions as may be appropriate to reflect such release. The Board of Directors of the General Partner may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if a Default or Event of Default is not continuing, the redesignation would not cause a Default or Event of Default and provided that, if at the time of such designation such Subsidiary is a Subsidiary Guarantor, after giving effect to such designation, the Partnership and its remaining Restricted Subsidiaries could incur at least $1.00 of additional Indebtedness under Section 4.09(a). 72

SECTION 4.16. BUSINESS ACTIVITIES. The Partnership shall not, and shall not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses. SECTION 4.17. SALE AND LEASEBACK TRANSACTIONS. The Partnership will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the Partnership or any Restricted Subsidiary that is a Subsidiary Guarantor may enter into a sale and leaseback transaction if: (a) the Partnership or that Subsidiary Guarantor, as applicable, could have (i) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under Section 4.09(a), and (ii) incurred a Lien to secure such Indebtedness pursuant to Section 4.11; provided, however, that clause (i) of this clause (a) shall be suspended during any period in which the Partnership and the Restricted Subsidiaries are not subject to the Suspended Covenants; (b) the gross cash proceeds of that sale and leaseback transaction are at least equal to the fair market value, as determined in good faith by the Board of Directors of the General Partner, of the property that is the subject of such sale and leaseback transaction; and (c) the transfer of assets in that sale and leaseback transaction is permitted by, and the Partnership applies the proceeds of such transaction in compliance with, Section 4.07. SECTION 4.18. PAYMENTS FOR CONSENT. The Partnership shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such considerations is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. SECTION 4.19. REPORTS. (a) Whether or not required by the SEC, so long as any Notes are outstanding, the Partnership will file with the SEC (unless the SEC will not accept such a filing) within the time periods specified in the SEC's rules and regulations and, upon request, the Partnership will furnish the Trustee for delivery to Holders upon their request: (i) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Partnership were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report on the annual financial statements by the Partnership's certified independent accountants; and 73

(ii) all current reports that would be required to be filed with the SEC on Form 8-K if the Partnership were required to file such reports. (b) If at the end of any such quarterly or annual period referred to in Section 4.19(a), the Partnership has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the Partnership shall deliver (promptly after such SEC filing referred to in Section 4.19(a)) to the Trustee for delivery to the Holders of the Notes quarterly and annual financial information required by Section 4.19(a) as revised to include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management's Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Partnership and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Partnership and the designated Joint Ventures of the Partnership. (c) In addition, whether or not required by the SEC, the Partnership will make such information available to securities analysts, investors and prospective investors upon request. In addition, upon request the Partnership shall furnish the Trustee such other non-confidential information, documents and other reports which the Partnership is required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act. (d) For so long as any Series A Notes remain outstanding (unless the Partnership is subject to the reporting requirements of the Exchange Act), the Partnership and the Securities Guarantors shall furnish to the Holders thereof, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to the extent such information is not provided pursuant to Sections 4.19(a) and 4.19(b). (e) Delivery of reports, information and documents to the Trustee pursuant to this Section 4.19 is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Partnership's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates). SECTION 4.20. SUSPENSION OF COVENANTS. During any period of time that the Notes have an Investment Grade Rating from both Rating Agencies and no Default has occurred and is continuing, the Partnership and the Restricted Subsidiaries shall not be subject to Sections 4.07, 4.08, 4.09, 4.12, 4.13, 4.17(a)(i) and 5.01(a)(iv)(B) (collectively, the "Suspended Covenants"); provided, however, that if the Partnership and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of this Section 4.20 and, subsequently, either of the Rating Agencies withdraws its ratings or downgrades the ratings assigned to the Notes below the Investment Grade Ratings so that the Notes do not have an Investment Grade Rating from both Rating Agencies, or a Default (other than with respect to the Suspended Covenants) occurs and is continuing, the Issuers and the Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants, subject to the terms, conditions and obligations set forth in this Indenture (each such date of reinstatement being the "Reinstatement Date"). Compliance with the Suspended Covenants with respect to Restricted Payments made after the Reinstatement Date 74

shall be calculated in accordance with Section 4.08 as though Section 4.08 had been in effect during the entire period of time from which the Notes are issued. ARTICLE 5 SUCCESSORS SECTION 5.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS. (a) Neither of the Issuers may, directly or indirectly: (x) consolidate or merge with or into another Person (whether or not such Issuer is the survivor); or (y) sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person; unless: (i) either: (A) such Issuer is the surviving entity; or (B) the Person formed by or surviving any such consolidation or merger (if other than such Issuer) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is an entity organized or existing under the laws of the United States, any state thereof or the District of Columbia (provided that El Paso Finance may not consolidate or merge with or into any entity other than a corporation satisfying such requirement for so long as the Partnership remains a partnership); (ii) the Person formed by or surviving any such consolidation or merger (if other than such Issuer) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made expressly assumes all the obligations of such Issuer under the Notes and this Indenture pursuant to agreements reasonably satisfactory to the Trustee; (iii) immediately after such transaction no Default or Event of Default exists; (iv) such Issuer or the Person formed by or surviving any such consolidation or merger (if other than such Issuer): (A) shall have Consolidated Net Worth immediately after the transaction equal to or greater than the Consolidated Net Worth of such Issuer immediately preceding the transaction; and (B) shall, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a); provided, however, that this clause (B) shall be suspended during any period in which the Partnership and the Restricted Subsidiaries are not subject to the Suspended Covenants; and 75

(C) has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and, if a supplemental indenture is required, such supplemental indenture comply with this Indenture and all conditions precedent therein relating to such transaction have been satisfied. (b) Notwithstanding Section 5.01(a), the Partnership is permitted to reorganize as any other form of entity in accordance with the procedures established in this Indenture; provided that: (i) the reorganization involves the conversion (by merger, sale, contribution or exchange of assets or otherwise) of the Partnership into a form of entity other than a limited partnership formed under Delaware law; (ii) the entity so formed by or resulting from such reorganization is an entity organized or existing under the laws of the United States, any state thereof or the District of Columbia; (iii) the entity so formed by or resulting from such reorganization assumes all of the obligations of the Partnership under the Notes and this Indenture pursuant to agreements reasonably satisfactory to the Trustee; (iv) immediately after such reorganization no Default or Event of Default exists; and (v) such reorganization is not adverse to the Holders of the Notes (for purposes of this clause (v) it is stipulated that such reorganization shall not be considered adverse to the Holders of the Notes solely because the successor or survivor of such reorganization (1) is subject to federal or state income taxation as an entity or (2) is considered to be an "includible corporation" of an affiliated group of corporations within the meaning of Section 1504(b)(i) of the Code or any similar state or local law). (c) Section 5.01(a) shall not apply to a merger or consolidation or any sale, assignment, transfer, lease, conveyance or other disposition of assets between or among the Partnership and any of its Restricted Subsidiaries. (d) No Subsidiary Guarantor may consolidate with or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person, whether or not affiliated with such Subsidiary Guarantor, but excluding the Partnership or another Subsidiary Guarantor, unless (i) subject to the provisions of Section 5.01(e), the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to the Subsidiary Guarantor's Guarantee of the Notes and the Indenture pursuant to a supplemental indenture and (ii) immediately after giving effect to such transaction, no Default or Event of Default exists. Any Subsidiary Guarantor may be merged or consolidated with or into any one or more Subsidiary Guarantors. 76

(e) In the event of a sale or other disposition of all or substantially all of the assets of any Subsidiary Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all or substantially all of the Equity Interests of any Subsidiary Guarantor, then such Subsidiary Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the Equity Interests of such Subsidiary Guarantor) or the Person acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor) will be released and relieved of any obligations under its Guarantee; provided that the Partnership applies the Net Proceeds of such sale or other disposition in accordance with the provisions set forth under Sections 3.09 and 4.07. SECTION 5.02. SUCCESSOR ENTITY SUBSTITUTED. (a) Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of an Issuer in accordance with Section 5.01 hereof, the surviving entity formed by such consolidation or into or with which such Issuer is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the "Partnership" or "El Paso Finance," as the case may be, shall refer instead to the surviving entity and not to the Partnership or El Paso Finance, as the case may be), and may exercise every right and power of the Partnership or El Paso Finance, as the case may be, under this Indenture with the same effect as if such successor Person had been named as an Issuer herein; provided, however, that the predecessor shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of an Issuer's assets that meets the requirements of Section 5.01 hereof. (b) If the surviving entity shall have succeeded to and been substituted for an Issuer, such surviving entity may cause to be signed, and may issue either in its own name or in the name of the applicable Issuer prior to such succession any or all of the Notes issuable hereunder which theretofore shall not have been signed by such Issuer and delivered to the Trustee; and, upon the order of such surviving entity, instead of such Issuer, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Notes which previously shall have been signed and delivered by the Officers of such Issuer to the Trustee for authentication, and any Notes which such surviving entity thereafter shall cause to be signed and delivered to the Trustee for that purpose (in each instance with notations of Guarantees thereon by the Subsidiary Guarantors). All of the Notes so issued and so endorsed shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued and endorsed in accordance with the terms of this Indenture and the Guarantees as though all such Notes had been issued and endorsed at the date of the execution hereof. (c) In case of any such consolidation, merger, continuance, sale, transfer, conveyance or other disposal, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued or the Guarantees to be endorsed thereon as may be appropriate. 77

(d) For all purposes of this Indenture and the Notes, Subsidiaries of any surviving entity will, upon such transaction or series of transactions, become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to this Indenture and all Indebtedness, and all Liens on property or assets, of the surviving entity and its Restricted Subsidiaries immediately prior to such transaction or series of transactions shall be deemed to have been incurred upon such transaction or series of transactions. ARTICLE 6 DEFAULTS AND REMEDIES SECTION 6.01. EVENTS OF DEFAULT.

(f) failure by an Issuer or any Restricted Subsidiary of the Partnership to pay final judgments aggregating in excess of $10.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; (g) except as permitted by this Indenture, any Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary Guarantor, shall deny or disaffirm its obligations under its Guarantee; (h) either Issuer or any Restricted Subsidiary of the Partnership that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Partnership that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law: (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a custodian of it or for all or substantially all of its property, (iv) makes a general assignment for the benefit of its creditors, or (v) generally is not paying its debts as they become due; and (i) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (i) is for relief against an Issuer or any Restricted Subsidiary of the Partnership that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Partnership that, taken as a whole, would constitute a Significant Subsidiary in an involuntary case; (ii) appoints a custodian of an Issuer or any Restricted Subsidiary of the Partnership that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Partnership that, taken as a whole, would constitute a Significant Subsidiary or for all or substantially all of the property of an Issuer or any Restricted Subsidiary of the Partnership that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Partnership that, taken as a whole, would constitute a Significant Subsidiary; or (iii) orders the liquidation of an Issuer or any Restricted Subsidiary of the Partnership that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Partnership that, taken as a whole, would constitute a Significant Subsidiary; and the order or decree remains unstayed and in effect for 60 consecutive days. 79

SECTION 6.02. ACCELERATION. If any Event of Default (other than an Event of Default specified in clauses (h) or (i) of Section 6.01 hereof) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (h) or (i) of Section 6.01 hereof occurs, all outstanding Notes shall be due and payable immediately without further action or notice. Notwithstanding the foregoing, so long as any Credit Facility shall be in full force and effect, if an Event of Default pursuant to clause (e) of Section 6.01 with regard to such Credit Facility shall have occurred and be continuing, the Notes shall not become due and payable until the earlier to occur of (x) five Business Days following delivery of written notice of such acceleration of the Notes to the agent under such Credit Facility and (y) the acceleration of any Indebtedness under such Credit Facility. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived. SECTION 6.03. OTHER REMEDIES. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest (and Liquidated Damages, if any) on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. SECTION 6.04. WAIVER OF PAST DEFAULTS. Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and/or interest, if any, or Liquidated Damages, if any, on, the Notes (including in connection with an offer to purchase) (provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 80

SECTION 6.05. CONTROL BY MAJORITY. Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. SECTION 6.06. LIMITATION ON SUITS. A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: (a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and (e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. SECTION 6.07. RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and interest and Liquidated Damages, if any, on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 6.08. COLLECTION SUIT BY TRUSTEE. If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover a judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium and interest and Liquidated Damages, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and 81

expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to an Issuer or any of the Subsidiary Guarantors (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10. PRIORITIES. If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order: First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; Second: subject to the subordination provisions of this Indenture, to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Liquidated Damages, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and Liquidated Damages, if any and interest, respectively; and Third: to the Issuers or the Subsidiary Guarantors or to such other party as a court of competent jurisdiction shall direct. The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 82

SECTION 6.11. UNDERTAKING FOR COSTS. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. ARTICLE 7 TRUSTEE SECTION 7.01. DUTIES OF TRUSTEE. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. (b) Except during the continuance of an Event of Default: (i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). (c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (i) this paragraph does not limit the effect of paragraph (b) of this Section; (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 83

(iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to any provision of this Indenture relating to the time, method and place of conducting any proceeding or remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture. (d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any claim, loss, liability or expense. (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Partnership or El Paso Finance. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. SECTION 7.02. RIGHTS OF TRUSTEE. (a) Subject to the provisions of Section 7.01(a) hereof, the Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. (b) Before the Trustee acts or refrains from acting in the administration of this Indenture, it may require an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. (c) The Trustee may execute any of its trusts or powers or perform any duties under this Indenture either directly by or through agents or attorneys, and may in all cases pay, subject to reimbursement as provided herein, such reasonable compensation as it deems proper to all such agents and attorneys employed or retained by it, and the Trustee shall not be responsible for any misconduct or negligence of any agent or attorney appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture. (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from an Issuer or any Subsidiary Guarantor shall be sufficient if signed by an Officer of the Partnership or the General Partner (in the case of the Partnership), by an Officer of 84

the General Partner (in the case of the General Partner) or by an Officer of El Paso Finance or any Subsidiary Guarantor (in the case of El Paso Finance or such Subsidiary Guarantor). (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity against the claims, costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. (g) The Trustee is not required to make any inquiry or investigation into facts or matters stated in any document but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee determines to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuers. (h) The Trustee is not required to take notice or shall not be deemed to have notice of any Default or Event of Default hereunder except Defaults or Events of Default under Sections 6.01(a) and 6.01(b) hereof, unless a Responsible Officer of the Trustee has actual knowledge thereof or has received notice in writing of such Default or Event of Default from the Issuers or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, and in the absence of any such notice, the Trustee may conclusively assume that no such Default or Event of Default exists. (i) The Trustee is not required to give any bond or surety with respect to the performance of its duties or the exercise of its powers under this Indenture. (j) In the event the Trustee receives inconsistent or conflicting requests and indemnity from two or more groups of Holders of Notes, each representing less than the aggregate principal amount of Notes outstanding required to take any action hereunder, the Trustee, in its sole discretion may determine what action, if any, shall be taken. (k) The Trustee's immunities and protections from liability and its right to indemnification in connection with the performance of its duties under this Indenture shall extend to the Trustee's officers, directors, agents, attorneys and employees. Such immunities and protections and right to indemnification, together with the Trustee's right to compensation, shall survive the Trustee's resignation of removal, the discharge of this Indenture and final payments of the Notes. (l) The permissive right of the Trustee to take actions permitted by this Indenture shall not be construed as an obligation or duty to do so. (m) Except for information provided by the Trustee concerning the Trustee, the Trustee shall have no responsibility for any information and any offering memorandum, disclosure material or prospectus distributed with respect to the Notes. 85

SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its commercial banking or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers, any Subsidiary Guarantors or any Affiliate of the Partnership with the same rights it would have if it were not Trustee. Any Affiliate of the Trustee or Agent may do the same with like rights and duties. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA) it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. The Trustee is also subject to Sections 7.10 and 7.11 hereof. SECTION 7.04. TRUSTEE'S DISCLAIMER. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or the Guarantees, it shall not be accountable for the Issuers' use of the proceeds from the Notes or any money paid to an Issuer or upon an Issuer's direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. SECTION 7.05. NOTICE OF DEFAULTS. If a Default or Event of Default known to the Trustee occurs, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest or Liquidated Damages, if any, on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES. Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c). A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Partnership and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA Section 313(d). The Issuers shall promptly notify the Trustee when the Notes are listed on any stock exchange. 86

SECTION 7.07. COMPENSATION AND INDEMNITY. The Issuers and the Subsidiary Guarantors shall pay to the Trustee from time to time such compensation as shall be agreed upon in writing between the Issuers and the Trustee for its acceptance of this Indenture and services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuers and the Subsidiary Guarantors shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. The Issuers and the Subsidiary Guarantors shall indemnify each of the Trustee or any successor Trustee against any and all losses, damages, claims, liabilities or expenses (including reasonable attorneys' fees and expenses) incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against either of the Issuers or any Subsidiary Guarantor (including this Section 7.07) and defending itself against any claim (whether asserted by an Issuer, any Subsidiary Guarantor, or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the Issuers and the Subsidiary Guarantors of their obligations hereunder. The Issuers and the Subsidiary Guarantors shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Issuers and the Subsidiary Guarantors shall pay the reasonable fees and expenses of such separate counsel. The Issuers and the Subsidiary Guarantors need not pay for any settlement made without their consent, which consent shall not be unreasonably withheld. The obligations of the Issuers and the Subsidiary Guarantors under this Section 7.07 shall survive the satisfaction and discharge of this Indenture. To secure the Issuers' and the Subsidiary Guarantors' payment obligations in this Section, the Trustee shall have a Lien (which it may exercise through right of set-off) prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal, premium, if any, and Liquidated Damages, if any, and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent applicable. 87

SECTION 7.08. REPLACEMENT OF TRUSTEE. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if: (a) the Trustee fails to comply with Section 7.10 hereof; (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; (c) a custodian or public officer takes charge of the Trustee or its property; or (d) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuers shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuers, any Subsidiary Guarantor or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.10, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers' and the Subsidiary Guarantors' obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 88

SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. SECTION 7.10. ELIGIBILITY; DISQUALIFICATION. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trust powers, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition. This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section 310(b), provided, however, that there shall be excluded from the operation of TIA Section 310(b)(l) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuers are outstanding if the requirements of such exclusion set forth in TIA Section 310(b)(l) are met. For purposes of the preceding sentence, the optional provision permitted by the second sentence of Section 310(b)(9) of the Trust Indenture Act shall be applicable. SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUERS. The Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. ARTICLE 8 LEGAL DEFEASANCE AND COVENANT DEFEASANCE SECTION 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE. The Issuers may, at the option of the Board of Directors of the General Partner (in the case of the Partnership) or of the Board of Directors of El Paso Finance (in the case of El Paso Finance) evidenced by a resolution set forth in an Officers' Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. SECTION 8.02. LEGAL DEFEASANCE AND DISCHARGE. Upon the Issuers' exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers and the Subsidiary Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their respective Obligations and certain other obligations with respect to all outstanding Notes and Guarantees, as applicable, on the date the conditions set forth below are satisfied (hereinafter, 89

"Legal Defeasance"). For this purpose, Legal Defeasance means that the Issuers and the Subsidiary Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (a) and (b) of this sentence below, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest and Liquidated Damages, if any, on such Notes when such payments are due (but not the Change of Control Payment or the payment pursuant to the Asset Sale Offer), (b) the Issuers' obligations with respect to such Notes under Sections 2.03, 2.04, 2.06, 2.07, 2.10 and 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers' and the Subsidiary Guarantors' obligations in connection therewith, (d) the Issuers' rights of optional redemption and (e) this Article 8. Subject to compliance with this Article 8, the Issuers may exercise the option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. SECTION 8.03. COVENANT DEFEASANCE. Upon the Issuers' exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and the Subsidiary Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 3.09, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.19 and 5.01(a)(iv) hereof and any covenant added to this Indenture subsequent to the Issue Date pursuant to Section 9.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuers may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuers' exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(c) through 6.01(g) hereof shall not constitute Events of Default. SECTION 8.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE. The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: 90

In order to exercise either Legal Defeasance or Covenant Defeasance: (a) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable U.S. Government Obligations, or a combination thereof, in such amounts as shall be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest, on the outstanding Notes at the Stated Maturity thereof or on the applicable redemption date, as the case may be, and the Partnership must specify whether the Notes are being defeased to maturity or to a particular redemption date; (b) in the case of an election under Section 8.02 hereof, the Issuers shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (A) the Partnership has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (c) in the case of an election under Section 8.03 hereof, the Partnership shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; (d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the incurrence of Indebtedness all or a portion of the proceeds of which shall be applied to such deposit) or insofar as Sections 6.01(h) and 6.01(i) hereof are concerned, at any time in the period ending on the 91st day after the date of deposit; (e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which either of the Issuers or any Restricted Subsidiary of the Partnership is a party or by which either of the Issuers or any Restricted Subsidiary of the Partnership is bound; (f) the Partnership shall have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally; (g) the Partnership shall have delivered to the Trustee an Officers' Certificate stating that the deposit was not made by such Issuer with the intent of preferring the Holders over any other creditors of such Issuer or the Subsidiary Guarantors or with the intent of defeating, hindering, delaying or defrauding other creditors of such Issuer; and 91

(h) the Partnership shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with. SECTION 8.05. DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS. Subject to Section 8.06 hereof, all money and non-callable U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including either Issuer acting as a Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, and Liquidated Damages, if any, but such money need not be segregated from other funds except to the extent required by law. The Issuers and the Subsidiary Guarantors shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuers from time to time upon the request of the Issuers any money or non-callable U.S. Government Obligations held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. SECTION 8.06. REPAYMENT TO ISSUERS. Any money deposited with the Trustee or any Paying Agent, or then held by an Issuer, in trust for the payment of the principal of, premium, if any, interest or Liquidated Damages, if any, on any Note and remaining unclaimed for two years after such principal, and premium, if any, interest or Liquidated Damages, if any, has become due and payable shall, subject to applicable escheat law, be paid to the Issuers on the request of the Issuers or (if then held by an Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a creditor, look only to the Issuers or Subsidiary Guarantors for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of such Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuers cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Issuers. 92

SECTION 8.07. REINSTATEMENT. If the Trustee or Paying Agent is unable to apply any United States dollars or U.S. Government Obligations in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers' and the Subsidiary Guarantors' Obligations under this Indenture, the Notes and the Guarantees, as applicable, shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuers or the Subsidiary Guarantors make any payment of principal of, premium, if any, interest or Liquidated Damages, if any, on any Note following the reinstatement of its Obligations, the Issuers and the Subsidiary Guarantors shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. ARTICLE 9 AMENDMENT, SUPPLEMENT AND WAIVER SECTION 9.01. WITHOUT CONSENT OF HOLDERS OF NOTES. Notwithstanding Section 9.02 of this Indenture, the Issuers and the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture, the Guarantees, or the Notes without the consent of any Holder of a Note: (a) to cure any ambiguity, defect or inconsistency; (b) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 hereof (including the related definitions) in a manner that does not materially adversely affect any Holder; (c) to provide for the assumption of an Issuer's or a Subsidiary Guarantor's obligations to the Holders of the Notes in the case of a merger or consolidation or sale of all or substantially all of such Issuer's or Subsidiary Guarantors' assets pursuant to Article 5 hereof; (d) to add or release Subsidiary Guarantors pursuant to the terms of this Indenture; (e) to make any change that would provide any additional rights or benefits to the Holders of the Notes or surrender any right or power conferred upon the Issuers or the Subsidiary Guarantors by this Indenture that does not adversely affect the legal rights hereunder of any Holder of the Notes; or (f) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; (g) to evidence or provide for the appointment under this Indenture of a successor Trustee; 93

(h) to add additional Events of Default; or (i) to secure the Notes and/or the Guarantees. Upon the request of the Issuers accompanied by a resolution of the Board of Directors of the General Partner (in the case of the Partnership), and of the Board of Directors of El Paso Finance and each of the Subsidiary Guarantors (in the case of El Paso Finance and the Subsidiary Guarantors), authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the Issuers and each of the Subsidiary Guarantors in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. SECTION 9.02. WITH CONSENT OF HOLDERS OF NOTES. Except as provided below in this Section 9.02, the Issuers, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture (including Sections 3.09, 4.06 and 4.07 hereof), the Guarantees, and the Notes with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Guarantees or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including consents obtained in connection with a tender offer or exchange offer for the Notes). Upon the request of the Issuers accompanied by a resolution of the Board of Directors of the General Partner (in the case of the Partnership) and of the Board of Directors of El Paso Finance and each of the Subsidiary Guarantors (in the case of El Paso Finance and each of the Subsidiary Guarantors) authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the Issuers and each of the Subsidiary Guarantors in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 94

After an amendment, supplement or waiver under this Section becomes effective, the Issuers shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuers to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding may waive compliance in a particular instance by the Issuers with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder): (a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; (b) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes, except as provided above with respect to Sections 3.09, 4.06 and 4.07 hereof; (c) reduce the rate of or change the time for payment of interest, including default interest, on any Note; (d) waive a Default or Event of Default in the payment of principal of or premium, if any, interest or Liquidated Damages, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); (e) make any Note payable in money other than that stated in the Notes; (f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or premium, if any, or interest on the Notes; (g) waive a redemption payment with respect to any Note (other than a payment required by the covenants contained in Sections 3.09, 4.06 or 4.07 hereof; (h) except as otherwise permitted by this Indenture, release any Subsidiary Guarantor from any of its obligations under its Guarantee or this Indenture, or change any Guarantee in any manner that would adversely affect the right of Holders; or (i) make any change in Section 6.04 or 6.07 hereof or in the foregoing amendment and waiver provisions (except to increase any percentage set forth therein). In addition, any amendment to the provisions of Article 10 or Section 11.07 of this Indenture (which relate to subordination) shall require the consent of the Holders of at least 75% in aggregate principal amount of the Notes then outstanding if such amendment would adversely affect the rights of Holders of Notes. 95

SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment or supplement to this Indenture, the Guarantees, or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect. SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. SECTION 9.05. NOTATION ON OR EXCHANGE OF NOTES. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuers in exchange for all Notes may issue and the Trustee shall authenticate new Notes (accompanied by a notation of the Guarantees duly endorsed by the Subsidiary Guarantors) that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC. The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuers and the Subsidiary Guarantors may not sign an amendment or supplemental Indenture until the Board of Directors of the General Partner approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01) shall be fully protected in relying upon, an Officers' Certificate of the Board of Directors of the General Partner and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. SECTION 9.07. EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution of any supplemental indenture under this Article 9, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. After a supplemental indenture becomes effective, the Issuers shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section. 96

ARTICLE 10 SUBORDINATION SECTION 10.01. AGREEMENT TO SUBORDINATE. The Issuers covenant and agree, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by, and any Liquidated Damages and other Obligations with respect to, the Notes are subordinated in right of payment, to the extent and in the manner provided in this Article 10, to the prior payment in full in cash of all Senior Debt (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of Senior Debt. SECTION 10.02. LIQUIDATION; DISSOLUTION; BANKRUPTCY. Upon any payment or distribution to creditors of either of the Issuers or any Subsidiary Guarantor in a liquidation or dissolution of such Issuer or such Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to such Issuer or such Subsidiary Guarantor or its property, in an assignment for the benefit of creditors or any marshaling of such Issuer's or such Subsidiary Guarantor's assets and liabilities: (a) holders of Senior Debt and holders of Guarantor Senior Debt shall be entitled to receive payment in full in cash of all Obligations in respect of Senior Debt and Guarantor Senior Debt (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Debt, whether or not such interest would be an allowed claim in such proceeding) before Holders of the Notes shall be entitled to receive any payment with respect to the Notes (except that Holders may receive and retain (i) Permitted Junior Securities and (ii) payments and other distributions made from any defeasance trust created pursuant to Article 8 hereof, provided that the funding of such trust was permitted); and (b) until all Obligations with respect to Senior Debt (as provided in subsection (a) above) are paid in full in cash, any payment or distribution to which Holders would be entitled but for this Article 10 shall be made to holders of Senior Debt (except that Holders of Notes may receive and retain (i) Permitted Junior Securities and (ii) payments and other distributions made from any defeasance trust created pursuant to Article 8 hereof, provided that the funding of such trust was permitted), as their interests may appear. SECTION 10.03. DEFAULT ON DESIGNATED SENIOR DEBT. The Issuers and the Subsidiary Guarantors may not make any payment or distribution in respect of Obligations with respect to the Notes (whether by redemption, purchase, defeasance or otherwise) and may not acquire any Notes for cash or property (other than (i) Permitted Junior Securities and (ii) payments and other distributions made from any defeasance trust created pursuant to Article 8 hereof, provided that the funding of such trust was permitted) until all principal and other Obligations with respect to the Senior Debt have been paid in full in cash if: 97

(a) a default in the payment of any principal, premium, if any, or interest (and other Obligations in the case of the Credit Facilities) on Designated Senior Debt occurs and is continuing; or (b) any other default on Designated Senior Debt occurs and is continuing that permits holders of the Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of the default (a "Payment Blockage Notice") from a Person who may give it pursuant to Section 10.11 hereof. If the Trustee receives any such Payment Blockage Notice, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until at least 360 days shall have elapsed since the effectiveness of the immediately prior Payment Blockage Notice. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice unless such default shall have been cured or waived for a period of not less than 120 days. The Issuers may and shall resume payments on and distributions in respect of the Notes and may acquire them upon the earlier of: (a) in the case of a default referred to in clause (a) of the immediately preceding paragraph, the date upon which the default is cured or waived, or (b) in the case of a default referred to in clause (b) of the immediately preceding paragraph, the earlier of the date on which such non-payment default is cured or waived and 179 days after the date on which the applicable Payment Blockage Notice is received by the Trustee unless the maturity of such Designated Senior Debt has been accelerated, if this Article 10 otherwise permits the payment, distribution or acquisition at the time of such payment or acquisition. SECTION 10.04. ACCELERATION OF NOTES. If payment of the Notes is accelerated because of an Event of Default, the Issuers shall promptly notify holders of Senior Debt of the acceleration. SECTION 10.05. WHEN DISTRIBUTION MUST BE PAID OVER. In the event that the Trustee or any Holder receives any payment of or distribution with respect to any Obligations with respect to the Notes at a time when such payment or distribution is prohibited by Section 10.02 or 10.03 hereof, such payment or distribution shall be held by the Trustee or such Holder, in trust for the benefit of, and shall be paid forthwith over and delivered, upon written request, to, the holders of Designated Senior Debt as their interests may appear or their Representative under this Indenture or other agreement (if any) pursuant to which such Designated Senior Debt may have been issued, as their respective interests may appear, for application to the payment in cash of all Obligations with respect to such Designated Senior Debt remaining unpaid to the extent necessary to pay such Obligations in full in cash in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of such Designated Senior Debt or holders of such Designated Guarantor Senior Debt. 98

With respect to the holders of Senior Debt, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this Article 10, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt, and shall not be liable to any such holders if the Trustee shall pay over or distribute to or on behalf of Holders or the Issuers or any other Person money or assets to which any holders of Senior Debt shall be entitled by virtue of this Article 10, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. SECTION 10.06. NOTICE BY ISSUERS. The Issuers shall promptly notify the Trustee and the Paying Agent of any facts known to the Issuers that would cause a payment of any Obligations with respect to the Notes to violate this Article 10, but failure to give such notice shall not affect the subordination of the Notes to the Senior Debt as provided in this Article 10. SECTION 10.07. SUBROGATION. After all Senior Debt is paid in full in cash and until the Notes are paid in full, Holders of Notes shall be subrogated (equally and ratably with all other Indebtedness pari passu with the Notes) to the rights of holders of Senior Debt to receive distributions applicable to Senior Debt to the extent that distributions otherwise payable to the Holders of Notes have been applied to the payment of Senior Debt. A distribution made under this Article 10 to holders of Senior Debt that otherwise would have been made to Holders of Notes is not, as between the Issuers and Holders, a payment by the Issuers on the Notes. SECTION 10.08. RELATIVE RIGHTS. This Article 10 defines the relative rights of Holders of Notes and holders of Senior Debt. Nothing in this Indenture shall: (a) impair, as between the Issuers and Holders of Notes, the obligation of the Issuers, which is absolute and unconditional, to pay principal of and interest on the Notes in accordance with their terms; (b) affect the relative rights of Holders of Notes and creditors of the Issuers other than their rights in relation to holders of Senior Debt; or (c) subject to Section 6.02, prevent the Trustee or any Holder of Notes from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Debt to receive distributions and payments otherwise payable to Holders of Notes. If the Issuers fail because of this Article 10 to pay principal of or interest on a Note on the due date, the failure is still a Default or Event of Default. 99

SECTION 10.09. SUBORDINATION MAY NOT BE IMPAIRED BY ISSUERS. No right of any holder of Senior Debt to enforce the subordination of the Indebtedness evidenced by the Notes shall be impaired by any act or failure to act by either of the Issuers or any Holder or by the failure of either of the Issuers or any Holder to comply with this Indenture. SECTION 10.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever a payment or distribution is to be made or a notice given to holders of Senior Debt, the payment or distribution may be made and the notice given to their Representative. Upon any payment or distribution of assets of either of the Issuers or any of the Subsidiary Guarantors referred to in this Article 10, the Trustee and the Holders of Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders of Notes for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Debt and other Indebtedness of such Issuer or Subsidiary Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 10. SECTION 10.11. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding the provisions of this Article 10 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Notes, unless a Responsible Officer of the Trustee shall have received at its Corporate Trust Office at least two Business Days prior to the date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Notes to violate this Article 10. Only the Issuers or the holders of Designated Senior Debt or their Representative may give the notice. Nothing in this Article 10 shall impair the claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof. Each Paying Agent shall be subject to the same obligations under this Article 10 as is the Trustee. The Trustee in its individual or any other capacity may hold Senior Debt with the same rights it would have if it were not Trustee. Any Affiliate of the Trustee or Agent may do the same with like rights. SECTION 10.12. AUTHORIZATION TO EFFECT SUBORDINATION. Each Holder of Notes, by the Holder's acceptance thereof, authorizes and directs the Trustee on such Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 10, and appoints the Trustee to act as such Holder's attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 6.09 hereof at least 30 days before the expiration of the time to file such claim, the Representative of 100

the Designated Senior Debt are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Notes. SECTION 10.13. AMENDMENTS. The provisions of this Article 10 shall not be amended or modified without the written consent of the holders of all Designated Senior Debt. ARTICLE 11 GUARANTEES SECTION 11.01. GUARANTEES. Subject to the provisions of this Article 11, each of the Subsidiary Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the Obligations of the Issuers hereunder or thereunder, that: (a) the principal of, premium, interest and Liquidated Damages, if any, on the Notes shall be promptly paid in full when due, whether at the maturity or interest payment or mandatory redemption date, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, interest and Liquidated Damages, if any, on the Notes, if any, if lawful, and all other Obligations of the Issuers to the Holders or the Trustee under this Indenture and the Notes shall be promptly paid in full or performed, all in accordance with the terms of this Indenture and the Notes; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Subsidiary Guarantors shall be jointly and severally obligated to pay the same immediately. The Subsidiary Guarantors hereby agree that to the fullest extent permitted by applicable law, their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions of this Indenture and the Notes, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. To the fullest extent permitted by applicable law, each Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenant that the Guarantees shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Issuers or Subsidiary Guarantors, or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or Subsidiary Guarantors, any amount paid by either to the Trustee or such Holder, these Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor agrees that it shall not be entitled to any right 101

of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby until payment in full of all Obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between the Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of these Guarantees, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such Obligations as provided in Article 6 hereof, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantors for the purpose of these Guarantees. The Subsidiary Guarantors shall have the right to seek contribution from any non-paying Subsidiary Guarantor so long as the exercise of such right does not impair the rights of the Holders under these Guarantees. SECTION 11.02. LIMITATION OF GUARANTOR'S LIABILITY. Each Subsidiary Guarantor and, by its acceptance hereof, each Holder hereby confirms that it is its intention that the Guarantee by such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to the Guarantees. To effectuate the foregoing intention, each such Person hereby irrevocably agrees that the Obligation of such Subsidiary Guarantor under its Guarantee under this Article 11 shall be limited to the maximum amount as shall, after giving effect to such maximum amount and all other (contingent or otherwise) liabilities of such Subsidiary Guarantor that are relevant under such laws, and after giving effect to any rights to contribution of such Subsidiary Guarantor pursuant to any agreement providing for an equitable contribution among such Subsidiary Guarantor and other Affiliates of the Issuers of payments made by guarantees by such parties, result in the Obligations of such Subsidiary Guarantor in respect of such maximum amount not constituting a fraudulent conveyance. Each Holder, by accepting the benefits hereof, confirms its intention that, in the event of bankruptcy, reorganization or other similar proceeding of either of the Issuers or any Subsidiary Guarantor in which concurrent claims are made upon such Subsidiary Guarantor hereunder, to the extent such claims shall not be fully satisfied, each such claimant with a valid claim against such Issuer shall be entitled to a ratable share of all payments by such Subsidiary Guarantor in respect of such concurrent claims. SECTION 11.03. EXECUTION AND DELIVERY OF GUARANTEES. To evidence the Guarantees set forth in Section 11.01 hereof, each Subsidiary Guarantor hereby agrees that a notation of the Guarantees substantially in the form of Exhibit D shall be endorsed by an Officer of such Subsidiary Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of such Subsidiary Guarantor by its President or one of its Vice Presidents. 102

Each Subsidiary Guarantor hereby agrees that the Guarantees set forth in Section 11.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of the Guarantees. If an Officer or Officer whose signature is on this Indenture or on the Guarantees no longer holds that office at the time the Trustee authenticates the Note on which the notation of the Guarantees are endorsed, the Guarantees shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantees set forth in this Indenture on behalf of the Subsidiary Guarantors. SECTION 11.04. SUBSIDIARY GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS. (a) Except as set forth in Articles 4 and 5 hereof, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of the Partnership or a Subsidiary Guarantor with or into the Partnership or another Subsidiary Guarantor or shall prevent any sale or conveyance of the property of a Subsidiary Guarantor as an entirety or substantially as an entirety, to the Partnership or another Subsidiary Guarantor. (b) Except as set forth in Articles 4 and 5 hereof, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Subsidiary Guarantor with or into another Person other than the Partnership or another Subsidiary Guarantor (whether or not affiliated with the Subsidiary Guarantor), or successive consolidations or mergers in which a Subsidiary Guarantor or its successor or successors shall be a party or parties, or shall prevent any sale or conveyance of the property of a Subsidiary Guarantor as an entirety or substantially as an entirety, to a person other than the Partnership (whether or not affiliated with the Subsidiary Guarantor) authorized to acquire and operate the same; provided, however, that such transaction meets all of the following requirements: (i) each Subsidiary Guarantor hereby covenants and agrees that, upon any such consolidation, merger, sale or conveyance, the Guarantee contained herein, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by such Subsidiary Guarantor, shall be expressly assumed (in the event that the Subsidiary Guarantor is not the surviving corporation in the merger or consolidation), by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee, by the Person formed by such consolidation, or into which the Subsidiary Guarantor shall have been merged, or by the Person which shall have acquired such property, and (ii) immediately after giving effect to such transaction, no Default or Event of Default exists. In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Guarantees contained herein and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Subsidiary Guarantor, such successor shall succeed to and be substituted for the Subsidiary Guarantor with the same effect as if it had been named herein as a Subsidiary Guarantor. Such successor thereupon may cause to be signed any or all of the notations of the Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuers and delivered to the Trustee. All the Guarantees so issued shall 103

in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution hereof. SECTION 11.05. RELEASES. Concurrently with any sale of assets (including, if applicable, all of the Equity Interests of any Subsidiary Guarantor), any Liens in favor of the Trustee in the assets sold thereby shall be released; provided that in the event of an Asset Sale, the Net Proceeds from such sale or other disposition are treated in accordance with the provisions of Section 4.07 hereof. The Guarantee or the obligations under Section 11.04 hereof of a Subsidiary Guarantor will be released (i) in connection with any sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor (including by way of merger or consolidation), if the Partnership applies the Net Proceeds of that sale or other disposition in accordance with Section 4.07 hereof; or (ii) in connection with the sale or other disposition of all of the Equity Interests of a Subsidiary Guarantor, if the Partnership applies the Net Proceeds of that sale in accordance with Section 4.07 hereof; or (iii) if the Partnership designates any Restricted Subsidiary that is a Subsidiary Guarantor as an Unrestricted Subsidiary; or (iv) at such time as such Subsidiary Guarantor ceases to guarantee any other Indebtedness of the Partnership. Upon delivery by the Partnership to the Trustee of an Officers' Certificate to the effect that such sale or other disposition was made by the Partnership in accordance with the provisions of this Indenture, including without limitation Section 4.07 hereof or such Guarantee is to be released pursuant to the provisions of the immediately preceding sentence, the Trustee shall execute any documents reasonably required in order to evidence the release of any Subsidiary Guarantor from its obligations under its Guarantees. Any Subsidiary Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Subsidiary Guarantor under this Indenture as provided in this Article 11. SECTION 11.06. "TRUSTEE" TO INCLUDE PAYING AGENT. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Issuers and be then acting hereunder, the term "Trustee" as used in this Article 11 shall in such case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if such Paying Agent were named in this Article 11 in place of the Trustee. SECTION 11.07. SUBORDINATION OF GUARANTEES. The obligations of each Subsidiary Guarantor under its Guarantee pursuant to this Article 11 shall be junior and subordinated to the prior payment in full in cash of all Senior Debt and Guarantor Senior Debt (including interest after the commencement of any proceeding of the type described in Section 10.02 with respect to such Subsidiary Guarantor at the rate specified in the applicable Guarantor Senior Debt, whether or not such interest would be an allowed claim in such proceeding) of such Subsidiary Guarantor, in each case on the same basis as the Notes are junior and subordinated to Senior Debt, mutatis mutandis. For the purposes of the foregoing sentence, the Trustee and the Holders shall have the right to receive and/or retain payments by 104

any of the Subsidiary Guarantors only at such times as they may receive and/or retain payments and distributions in respect of the Notes pursuant to this Indenture, including Article 10 hereof. ARTICLE 12 SATISFACTION AND DISCHARGE SECTION 12.01. SATISFACTION AND DISCHARGE. This Indenture shall upon the request of the Issuers cease to be of further effect (except as to surviving rights of registration of transfer or exchange of Notes herein expressly provided for, the Issuers' obligations under Section 7.07 hereof, the Issuers' rights of optional redemption under Article 3 hereof, and the Trustee's and the Paying Agent's obligations under Section 12.02 and 12.03 hereof) and the Trustee, at the expense of the Issuers, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture when (a) either (i) all Notes therefore authenticated and delivered (other than (A) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.07 and (B) Notes for whose payment money has been deposited in trust with the Trustee or any Paying Agent and thereafter paid to the Issuers or discharged from such trust) have been delivered to the Trustee for cancellation; or (ii) all such Notes not theretofore delivered to the Trustee for cancellation (A) have become due and payable; or (B) shall become due and payable at their Stated Maturity within one year, or (C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuers, and the Issuers, in the case of clause (A), (B) or (C) above, have irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose money or U.S. Government Obligations in an amount sufficient (as certified by an independent public accountant designated by the Issuers) to pay and discharge the entire indebtedness of such Notes not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest, if any, to the date of such deposit (in the case of Notes which have become due and payable) or the Stated Maturity or redemption date, as the case may be; (b) the Issuers have paid or caused to be paid all other sums then due and payable hereunder by the Issuers; 105

(c) no Default or Event of Default with respect to the Notes shall have occurred and be continuing on the date of such deposit and after giving effect to such deposit; and (d) the Issuers have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the Issuers' obligations in Sections 2.03, 2.04, 2.06, 2.07, 2.11, 7.07, 7.08, 12.02, 12.03 and 12.04, and the Trustee's and Paying Agent's obligations in Section 12.03 shall survive until the Notes are no longer outstanding. Thereafter, only the Issuers' obligations in Section 12.03 shall survive. In order to have money available on a payment date to pay principal (and premium, if any, on) or interest on the Notes, the U.S. Government Obligations shall be payable as to principal (and premium, if any) or interest at least one Business Day before such payment date in such amounts as shall provide the necessary money. The U.S. Government Obligations shall not be callable at the issuer's option. SECTION 12.02. APPLICATION OF TRUST. All money deposited with the Trustee pursuant to Section 12.01 shall be held in trust and, at the written direction of the Issuers, be invested prior to maturity in non-callable U.S. Government Obligations, and applied by the Trustee in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for the payment of which money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. SECTION 12.03. REPAYMENT OF THE ISSUERS. The Trustee and the Paying Agent shall promptly pay to the Issuers upon written request any excess money or securities held by them at any time. The Trustee and the Paying Agent shall notify the Issuers of, and pay to the Issuers upon written request, any money held by them for the payment of principal or interest that remains unclaimed for two years after the date upon which such payment shall have become due; provided that the Issuers shall have either caused notice of such payment to be mailed to each Holder of the Notes entitled thereto no less than 30 days prior to such repayment or within such period shall have published such notice in a financial newspaper of widespread circulation published in The City of New York, including, without limitation, The Wall Street Journal (national edition). After payment to the Issuers, Holders entitled to the money must look to the Issuers for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease. In the absence of a written request from the Issuers to return unclaimed funds to the Issuers, the Trustee shall from time to time deliver all unclaimed funds to or as directed by applicable escheat authorities, as determined by the Trustee in its sole discretion, in accordance with the customary practices and procedures of the Trustee. Any unclaimed funds held by the 106

Trustee pursuant to this Section 12.03 shall be held uninvested and without any liability for interest. SECTION 12.04. REINSTATEMENT. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 12.01 by reason of any legal proceeding or by reason of any order or judgment of any court of governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers' and Subsidiary Guarantors' Obligations under this Indenture, the Notes and the Guarantees shall be revived and reinstated as though no deposit has occurred pursuant to Section 12.01 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with Section 12.02, provided, however, that if the Issuers or the Subsidiary Guarantors have made any payment of interest on or principal of any Notes because of the reinstatement of their Obligations, the Issuers or such Subsidiary Guarantors shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

SECTION 13.05. STATEMENTS REQUIRED IN CERTIFICATE OR OPINION. Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA Section 314(a)(4)) shall comply with the provisions of TIA Section 314(e) and shall include: (a) a statement that the Person making such certificate or opinion has read such covenant or condition; (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; (c) a statement that, in the opinion of such Person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been satisfied; and 109

(d) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been satisfied. SECTION 13.06. RULES BY TRUSTEE AND AGENTS. The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions.

All agreements of the Issuers and the Subsidiary Guarantors in this Indenture, the Notes and the Guarantees shall bind its successors. All agreements of the Trustee in this Indenture shall bind their respective successors. SECTION 13.11. SEVERABILITY.

Interest.

The Issuers will pay interest and Liquidated Damages, if any, semi-annually on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an "Interest Payment Date"). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the Issue Date; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be June 1, 2003. The Issuers shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the rate then in effect; the Issuers shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated Damages (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 2. Method of Payment. The Issuers will pay interest on the Notes (except defaulted interest) and Liquidated Damages to the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15 next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest and Liquidated Damages, if any, at the office or agency of the Paying Agent and Registrar maintained for such purpose within the City and State of New York, or, at the option of the Issuers, payment of interest and Liquidated Damages, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest, premium and Liquidated Damages, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuers or the Paying Agent.

Initially, JPMorgan Chase Bank, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The Issuers or any of the Subsidiary Guarantors may act in any such capacity. Exhibit A Page 4

4. Indenture. The Issuers issued the Notes under an Indenture dated as of March 24, 2003 ("Indenture") among the Issuers, the Subsidiary Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured general obligations of the Issuers. Payment of the Notes and Guarantees and related obligations are subordinated to the prior payment in full in cash of Senior Debt and Guarantor Senior Debt to the extent provided in the Indenture. 5. Optional Redemption. (a) Except as set forth in subparagraph (b) of this Paragraph 5, the Issuers shall not have the option to redeem the Notes prior to June 1, 2007. From and after June 1, 2007, the Issuers shall have the option to redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days' notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, and Liquidated Damages, if any, thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on June 1st of the years indicated below:

YEAR PERCENTAGE - ---- ---------- 2007............................................................... 104.250% 2008............................................................... 102.125% 2009 and thereafter................................................ 100%
(b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to June 1, 2006, the Issuers may (but shall not have the obligation to) redeem, on one or more occasions, up to an aggregate of 33% of the aggregate principal amount of Notes originally issued under this Indenture at a redemption price equal to 108.500% of the principal amount thereof, plus accrued and unpaid interest and Liquidated Damages, if any, thereon, to the redemption date, with the net cash proceeds of one or more Equity Offerings; provided that at least 67% of the aggregate principal amount of Notes remains outstanding immediately after the occurrence of such redemption (excluding for purposes of determining the Notes that remain outstanding any Notes held by the Issuers or any Restricted Subsidiary of the Partnership); and provided further, that such redemption shall occur within 90 days of the date of the closing of such Equity Offering. 6. Mandatory Redemption. Except as set forth in paragraph 7 below, the Issuers shall not be required to make mandatory redemption payments with respect to the Notes. 7. Repurchase at Option of Holder. (a) If there is a Change of Control, each Holder of Notes will have the right to require the Issuers to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder's Notes (the "Change of Control Offer") at a purchase price equal to 101% of the Exhibit A Page 5

aggregate principal amount of the Notes repurchased plus accrued and unpaid interest, if any, thereon, and Liquidated Damages, if any, thereon, to the date of purchase.
