ARTICLE 2
Guarantee and Indemnification

Section 2.01 Guarantee.

(a) Without limiting Section 2.09(c), Anadarko hereby unconditionally and irrevocably guarantees to Trinity and its indorsees, transferees, successors and assigns, the

prompt and complete payment when due (whether at the stated maturity, by acceleration or otherwise) of the WGRAH Obligations. For the sake of clarity, WGRAH shall remain the primary obligor for payment of the WGRAH Obligations and Anadarko is the guarantor of such obligations.

(b) Anadarko and by its acceptance of this Sponsor Payment Guaranty and the rights hereunder or benefits hereof, Trinity, hereby agrees and confirms that it is the intention of all such Persons that this Sponsor Payment Guaranty and the obligations of Anadarko under this Article 2 not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Laws, the Uniform Fraudulent Conveyance Act (as adopted by any applicable state), the Uniform Fraudulent Transfer Act (as adopted by any applicable state) or any similar foreign, federal or state law to the extent applicable to this Sponsor Payment Guaranty and the obligations of Anadarko under this Article 2 and (ii) the aggregate liability of Anadarko under this Article 2 at any time shall not exceed its Maximum Liability.

(c) Anadarko agrees that the WGRAH Obligations may at any time and from time to time exceed the Maximum Liability of Anadarko hereunder without impairing the guarantee contained in this Article 2 or affecting the rights and remedies of Trinity hereunder.

(d) Without limiting Section 2.09(c), the guarantee contained in this Article 2 shall remain in full force and effect until the earlier of irrevocable payment in full of the WGRAH Obligations or irrevocable payment in full of the Liquidated Damages and any other Sponsor Indemnified Amounts.

(e) Without limiting Section 2.09(c), no payment or payments made by WGRAH, Anadarko, any other guarantor or any other Person, or received or collected by Trinity from WGRAH, Anadarko, any other guarantor or any other Person, by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of WGRAH Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of Anadarko under this Article 2 which shall, notwithstanding any such payment or payments (other than any payment or payments made by Anadarko in respect of the WGRAH Obligations or any payment received or collected from Anadarko in respect of the WGRAH Obligations), remain liable for the WGRAH Obligations up to the Maximum Liability of Anadarko under this Article 2 until the earlier of irrevocable payment in full of the WGRAH Obligations or irrevocable payment in full of the Liquidated Damages and any other Sponsor Indemnified Amounts.

(f) Without limiting Section 2.09(c), Anadarko hereby absolutely, unconditionally and irrevocably guarantees, for the benefit of the Indemnified Persons, the due and punctual payment, performance and observance by each of Trinity and the Trinity Managing Member (in the case of the Trinity Managing Member, such guarantee provided as long as the Trinity Class A Member is an Affiliate of Anadarko) of their respective Responsibilities under each Transaction Agreement to which they are a party.

Section 2.02 No Subrogation. Notwithstanding any payment made by Anadarko hereunder or any set-off or application of funds of Anadarko by Trinity, Anadarko shall not be entitled to be subrogated to any of the rights of Trinity against WGRAH or any collateral

security or guarantee or right of offset held by Trinity for the payment of WGRAH Obligations, nor shall Anadarko seek or be entitled to seek any contribution or reimbursement from WGRAH in respect of payments made by Anadarko hereunder, until the earlier of irrevocable payment in full of the WGRAH Obligations or irrevocable payment in full of the Liquidated Damages and any other Sponsor Indemnified Amounts. All debts, obligations and liabilities of WGRAH to Anadarko, whether now existing or hereafter arising, shall be expressly subordinate in payment to the payment and satisfaction in full of the WGRAH Obligations until the earlier of the irrevocable payment in full of the WGRAH Obligations and the irrevocable payment in full of the Liquidated Damages and any other Sponsor Indemnified Amounts. If any amount shall be paid to Anadarko on account of such subrogation rights prior to the payment in full of the WGRAH Obligations or the Liquidated Damages and any other Sponsor Indemnified Amounts, such amount shall be held by Anadarko in trust for Trinity, segregated from other funds of Anadarko, and shall, forthwith upon receipt by Anadarko, be turned over to Trinity in the exact form received by Anadarko (duly indorsed by Anadarko to Trinity, if required), to be applied against WGRAH Obligations, whether matured or unmatured, in accordance with the terms and provisions of the WGRAH Loan Agreement.

Section 2.03 Amendments, etc. with Respect to the WGRAH Obligations. Anadarko shall remain obligated under this Article 2 notwithstanding that, without any reservation of rights against Anadarko and without notice to or further assent by Anadarko, (a) any demand for payment of any of the WGRAH Obligations made by Trinity may be rescinded by Trinity and any of the WGRAH Obligations continued, (b) any WGRAH Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by Trinity, and (c) the WGRAH Loan Agreement or the other WGRAH Loan Documents and any other documents executed and delivered in connection therewith, in each case may be amended, modified, supplemented or terminated, in whole or in part, pursuant to the terms and conditions of each such applicable document from time to time, and any collateral security, guarantee or right of offset at any time held by Trinity for the payment of any WGRAH Obligations may be sold, exchanged, waived, surrendered or released.

Section 2.04 Guarantee Absolute and Unconditional. Anadarko waives any and all notice of the creation, renewal, extension or accrual of any of the WGRAH Obligations and notice of or proof of reliance by Trinity upon the guarantee contained in this Article 2 or acceptance of the guarantee contained in this Article 2. Anadarko waives diligence, presentment, protest, demand for payment (except as expressly set forth in this Section 2.04), notice of intent to accelerate, notice of acceleration and notice of default or nonpayment to or upon WGRAH or Anadarko with respect to WGRAH Obligations. Anadarko further waives any requirement that suit be brought against WGRAH, or any other action by Trinity be taken against WGRAH or any other Person, or that any other action to be taken or not taken as a condition to Anadarko’s liability for the WGRAH Obligations under this Sponsor Payment Guaranty or as a condition to the enforcement of this Sponsor Payment Guaranty against Anadarko. Anadarko understands and agrees that the guarantee contained in this Article 2 shall, without limiting Section 2.09(c), be construed as a continuing, absolute, irrevocable and unconditional guarantee of payment without regard to (a) the validity or enforceability or perfection of the WGRAH Loan Agreement or any other WGRAH Loan Document or Transaction Agreement, any of the WGRAH

Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by Trinity, (b) any defense (including any defense arising from the bankruptcy or insolvency of WGRAH or Anadarko), set-off or counterclaim whatsoever (other than a defense of payment or performance) which may at any time be available to or be asserted by WGRAH or any other Person against Trinity, or (c) any other circumstance whatsoever (with or without notice to or knowledge of WGRAH or Anadarko), other than payment or performance, which constitutes, or might be construed to constitute, an equitable or legal discharge of WGRAH or Anadarko for any of its respective portion of the WGRAH Obligations or of Anadarko under the guarantee contained in this Article 2, in bankruptcy or in any other instance. Without limiting Section 2.09(c), Anadarko shall pay the WGRAH Obligations when due upon written demand therefor specifying the WGRAH Obligation due and amount thereof; provided, that when making any demand hereunder or otherwise pursuing its rights and remedies hereunder against Anadarko, Trinity may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against WGRAH or any other Person or against any collateral security or guarantee for the WGRAH Obligations or any right of offset with respect thereto, and any failure by Trinity to make any such similar demand, to pursue such other rights or remedies or to collect any payments from WGRAH or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of WGRAH or any other Person or any such collateral security, guarantee or right of offset, shall not relieve Anadarko of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of Trinity against Anadarko. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings. It shall not be necessary for Trinity, in order to enforce payment by Anadarko under this Sponsor Payment Guaranty, to institute or exhaust its remedies against WGRAH, any other guarantor, or any other person liable for the payment or performance of the WGRAH Obligations.

Section 2.05 Reinstatement. The guarantee contained in this Article 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the WGRAH Obligations is rescinded or must otherwise be restored or returned by Trinity upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of WGRAH or Anadarko, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, WGRAH, or Anadarko or any substantial part of its property, or otherwise, all as though such payments had not been made.

Section 2.06 Payments to Trinity. Anadarko hereby agrees that payments required to be made by it hereunder to Trinity will be paid to Trinity without set-off or counterclaim in dollars before 12:00 noon, New York City time, on the day when due and shall be made to the Trinity Operating Account.

Section 2.07 General Indemnities. Without limiting Section 2.09 below, Anadarko agrees to the fullest extent permitted by Applicable Law to indemnify and hold harmless each Indemnified Person for and against and to pay on an After Tax-Basis, all Expenses (the Expenses on an After-Tax Basis and any liquidated damages provided for under the second sentence of Section 2.07(a) being referred to collectively as the “Sponsor Indemnified Amounts‘) that may be incurred or realized by or asserted against such Indemnified Person relating to, growing out of or resulting from:

(a) Trinity Bankruptcy Event. Any Trinity Bankruptcy Event; provided, that forthwith upon the occurrence of a Trinity Bankruptcy Event and in respect of Sponsor Indemnified Amounts under the first clause of this sentence the Indemnified Parties shall be entitled to receive (and Anadarko shall pay) as liquidated damages (the “Liquidated Damages”) but without prejudice to amounts recoverable under Section 2.07(c) or Section 2.07(e) below or any other provision of the Transaction Agreements, and not as a penalty, an aggregate amount equal to the sum of all (x) Unrecovered Capital plus (y) the Cumulative Preferred Return Distribution Amount at the time of redemption, plus (z) all Trinity Expenses then unpaid in addition to, but without duplication of, all Expenses payable pursuant to the first sentence of this Section 2.07; or

(b) Failure to Perform. The failure of the Trinity Managing Member to timely perform any Trinity Required Action; or

(c) Enforcement or Defense. (i) Enforcement of this Sponsor Payment Guaranty or any other Transaction Agreement and (ii) any investigation, litigation or proceeding, whether or not such Indemnified party is a party thereto, that: (A) relates to, grows out of or results from any action or omission, or alleged action or omission, by or on behalf of or attributable to any Transaction party in the performance or observance of its obligations under or in relation to the Transaction Agreements or the transactions contemplated thereby; and (B) would not have resulted in Sponsor Indemnified Amounts incurred or realized by or asserted against such Indemnified Person but for their being a party to, or a direct or indirect participant in, or having a relationship described in the definition of “Indemnified Person” to a party to, or a direct or indirect participant in, the Transaction Agreement or any of the transactions contemplated thereby; or

(d) ERISA. Any liability or other Sponsor Indemnified Amounts that Trinity or any other Transaction Party may incur in connection with any Plan or Multiemployer Plan or otherwise under Title IV of ERISA; or

(e) Expenses. Any amendment, supplement, modification, consent or waiver of, to or under any Transaction Agreement (to the extent not otherwise reimbursed pursuant to any Transaction Agreement); or

(f) Fraudulent Transfer or Conveyance. Any transfer, pledge or conveyance by any Transaction Party to Trinity Holdings, WGRAH or any of their Subsidiaries or the transfer, pledge or conveyance thereof under the WGRAH Loan Documents to the extent found in any bankruptcy, insolvency, receivership or other similar proceeding to be a “fraudulent transfer” or “fraudulent conveyance” or “fraudulent preference”; or

(g) Tax Liability. All Taxes for which Anadarko or any of its Subsidiaries is liable (including with respect to any assets or income of a partnership or disregarded entity owned in whole or in part by Anadarko or any of its Subsidiaries). If the shares of any Transaction Party and any assets directly or indirectly held thereby (including any assets hold by any partnership or

disregarded entity in which a Transaction Party is a partner or owner) are sold following a Liquidating Event, the benefits of this Section 2.07(g) shall inure to the purchaser of such shares or assets with respect to any taxable period or portion thereof ending on or prior to the date of such sale.

Section 2.08 Survival of Indemnification Obligations.

For purposes of this Section 2.09(b), it is agreed that Trinity is not a Related Person of Pecos.

(c) No Duplication. Sponsor Indemnified Amounts under Section 2.07 shall be without duplication of (i) any amounts paid under indemnification provisions of any other Transaction Agreement or other agreement or any amounts actually paid thereunder and (ii) any amounts paid by the Sponsor in respect of WGRAH Obligations pursuant to Section 2.04.

(d) Exculpation. ANADARKO, ON BEHALF OF ITSELF AND ITS AFFILIATES, AGREES THAT NO INDEMNIFIED PERSON SHALL BE LIABLE TO ANADARKO OR ANY OF ITS AFFILIATES FOR ANY ACTION IN GOOD FAITH TAKEN OR OMITTED TO BE TAKEN BY SUCH INDEMNIFIED PERSON PURSUANT TO, IN CONNECTION WITH, OR IN ANY WAY RELATED TO THIS SPONSOR PAYMENT GUARANTY OR ANY OTHER TRANSACTION AGREEMENT, INCLUDING AN INDEMNIFIED PERSON’S OWN NEGLIGENCE OR CO-NEGLIGENCE EXCEPT TO THE EXTENT SUCH ACTION OR OMISSION CONSTITUTES WILLFUL MISCONDUCT, FRAUD OR GROSS NEGLIGENCE ON THE PART OF SUCH INDEMNIFIED PERSON.

Section 2.10 Procedural Requirements.

(a) Notice of Claims. Any Indemnified Person that proposes to assert a right to be indemnified under Section 2.07 or Section 2.12 (together, the “Indemnification Sections”) will, promptly after receipt of notice of commencement of any action, suit, or proceeding against such Indemnified Person in respect of which a claim is to be made against Anadarko under an Indemnification Section (a “Sponsor Indemnified Proceeding”), or the incurrence or realization of Sponsor Indemnified Amounts in respect of which a claim is to be made against Anadarko, under an Indemnification Section, notify Anadarko of the commencement of such Sponsor Indemnified Proceeding or of such incurrence or realization, enclosing a copy of all relevant documents, including all papers served and claims made, but the omission so to notify Anadarko promptly of any such Sponsor Indemnified Proceeding or incurrence or realization shall not relieve (i) Anadarko from any liability that it may have to such Indemnified Person under the Indemnification Sections or otherwise, except, as to Anadarko’s liability, under the Indemnification Sections, to the extent, but only to the extent, that Anadarko shall have been prejudiced by such omission or (ii) any other indemnitor from liability that it may have to any Indemnified Person under the Transaction Agreements.

(b) Defense of Proceedings. In case any Sponsor Indemnified Proceeding shall be brought against any Indemnified Person and it shall notify Anadarko of the commencement thereof, Anadarko shall be entitled to participate in, and to assume the defense of, such Sponsor Indemnified Proceeding with counsel reasonably satisfactory to such Indemnified Person, and after notice from Anadarko to such Indemnified Person of Anadarko’s election so to assume the defense thereof and the failure by such Indemnified Person to object to such counsel within ten (10) Business Days following its receipt of such notice, Anadarko shall not be liable to such Indemnified Person for legal or other expenses incurred after such notice of election to assume such defense except as provided below and except for the reasonable costs of investigating, monitoring or cooperating in such defense subsequently incurred by such Indemnified Person reasonably necessary, in connection with the defense thereof; provided that without the prior written consent of such Indemnified Person, Anadarko shall not settle or compromise, or consent to the entry of any judgment in, any pending or threatened Sponsor Indemnified Proceeding, unless such settlement, compromise or consent or related judgment includes an unconditional release of such Indemnified Person from all liability for Expenses arising out of such claim, action, investigation, suit or other legal proceeding. No Indemnified Person shall settle or compromise, or consent to the entry of any judgment in, any pending or threatened Sponsor Indemnified Proceeding in respect of which any payment would result hereunder or under the other Transaction Agreements without the prior written consent of Anadarko, such consent not to be unreasonably withheld or delayed. Such Indemnified Person shall have the right to employ its separate counsel in any such Sponsor Indemnified Proceeding, in which case the fees and expenses of counsel for such Indemnified Person shall be at the expense of the Indemnified Person unless (i) Anadarko and the Indemnified Person shall have mutually agreed to the retention of such counsel and the payment of fees and expenses thereof by Anadarko, (ii) the use of counsel chosen by Anadarko to represent the Indemnified Person would present such counsel with a conflict of interest, (iii) the actual or potential parties to any Sponsor Indemnified

Proceeding (including any impleaded parties) include both Anadarko and an Indemnified Party and the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to Anadarko, or (iv) Anadarko shall have failed to retain satisfactory counsel as provided herein

Section 2.11 Contributory Negligence. The indemnities set forth herein shall expressly include any Sponsor Indemnified Amounts attributable to the ordinary, sole or contributory negligence of any Indemnified Person.

Section 2.12 Indemnification of Pecos Administrator and Trinity Custodian. Without limiting Section 2.09, Anadarko agrees to the fullest extent permitted by Applicable Law to (a) indemnify and hold harmless each of the “Indemnified Parties” (as such term is defined in the Pecos Administration Agreement) to the same extent that Pecos is required to indemnify such persons in accordance with Section 7 of the Pecos Administration Agreement, and (b) indemnify and hold harmless each of the “Indemnified Parties” (as such term is defined in the Trinity Custodian Agreement) to the same extent that Trinity is required to indemnify such persons in accordance with Section 7 of the Trinity Custodian Agreement.

Section 2.13 Payments in Respect of Indemnification Sections. All payments to be made by Anadarko under the Indemnification Sections shall be paid by Anadarko within five (5) Business Days following demand therefor, accompanied, as may be appropriate in the context, by supporting documentation in reasonable detail. Payment shall be made to the bank account or at another location as such Indemnified Person shall designate in writing or as is expressly required under any Transaction Agreement the obligations under which are the subject of any such payment, not later than 1:00 P.M. (New York time) on the date for such payment in immediately available funds.

Section 2.14 Taxes.

(a) Any and all payments by Anadarko under the Indemnification Sections to each Indemnified Person shall be made, in accordance with Section 2.14, free and clear of and without deduction for any and all present or future Taxes. If Anadarko shall be required by Applicable Law to deduct any Taxes from or in respect of any sum payable under the Indemnification Sections to any Indemnified Person, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.14) such Indemnified Person receives an amount equal to the sum it would have received had no such deductions been made, (ii) Anadarko shall make or cause to be made such deductions and (iii) Anadarko shall pay or cause to be paid the full amount deducted to the relevant taxation authority or other authority in accordance with Applicable Law, provided that should an Indemnified Person become subject to Taxes because of its failure to deliver a form required under Section 2.14(d), Anadarko shall take such steps as such Indemnified Person shall reasonably request to assist such Indemnified Person to recover such Taxes, and provided further; that each Indemnified Person, with respect to itself, agrees to indemnify and hold harmless Anadarko from any taxes, penalties, interest or other expenses, costs and losses incurred or payable by Anadarko as a result of the failure of Anadarko to comply with its obligations under Section 2.14(a)(ii) or (iii) in reliance on any form or certificate provided to it by such Indemnified Person pursuant to Section 2.14(d). If any Indemnified

Person receives a net credit, refund or reduction in Taxes in respect of such Taxes or amounts so paid by Anadarko, it shall promptly notify Anadarko of such net credit, refund or reduction in Taxes and shall promptly pay such net credit, refund or reduction in Taxes to Anadarko, provided that Anadarko agrees to return such net credit, refund or reduction in Taxes if the Indemnified Person to which such net credit, refund or reduction in Taxes is applicable is required to repay it.

(b) In addition, Anadarko agrees to pay any present or future stamp or documentary Taxes or any other excise or property Taxes, charges or similar levies, which arise from any payment made by Anadarko under the Indemnification Sections or from the execution, delivery or performance of, or otherwise with respect to, this Sponsor Payment Guaranty (hereinafter referred to as “Other Sponsor Taxes”).

(c) Anadarko will indemnify each Indemnified Person for the full amount of Taxes or Other Sponsor Taxes (including, without limitation, any Taxes or Other Sponsor Taxes imposed by any jurisdiction on amounts payable under this Section 2.14) paid by such Indemnified Person and any liability (including penalties, interest and expenses) arising, therefrom or with respect thereto except as a result of the gross negligence (which shall in any event include the failure of such Indemnified Person to provide to Anadarko any form or certificate that it was required to provide pursuant to subsection (d) below and such Indemnified Person was able to provide under Applicable Law) or willful misconduct of such Indemnified Person, whether or not such Taxes or Other Sponsor Taxes were correctly or legally asserted. This indemnification shall be made within thirty (30) days from the date such Indemnified Person makes written demand therefor.

(d) On or prior to the date on which each Indemnified Person organized under the laws of a jurisdiction outside the United States becomes an Indemnified Person hereunder, such Indemnified Person to the extent permitted under Applicable Law, shall provide Anadarko with U.S. Internal Revenue Service form W-BEN or W-8ECI, as appropriate, or any successor form prescribed by the U.S. Internal Revenue Service, certifying that such Indemnified Person is fully exempt from or subject to a reduced rate of United States withholding taxes with respect to all payments to be made to such Indemnified Person under the Indemnification Sections, or other documents satisfactory to Anadarko indicating that all payments to be made to such Indemnified Person under the Indemnification Sections are fully exempt from or subject to a reduced rate of such taxes. Thereafter and from time to time (but only so long as such Indemnified Person remains lawfully able to do so), each such Indemnified Person shall submit to Anadarko such additional duly completed and signed copies of one or the other of such forms (or such successor forms as shall be adopted from time to time by the relevant U.S. taxing authorities) as may be (i) requested by Anadarko from such Indemnified Person and (ii) required under then-current U.S. law or regulations to avoid or reduce U.S. withholding taxes on payments in respect of all amounts to be received by such Indemnified Person pursuant to this Sponsor Payment Guaranty. Each Indemnified Person that is a U.S. person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to Anadarko a certificate to the effect that it is such a U.S. person. If any Indemnified Person determines as a result of any change in Applicable Law, or in any official application or interpretation thereof, that it is unable to submit to Anadarko any form or certificate that such Indemnified Person is obligated to submit pursuant to this subsection (d), or that such Indemnified Person is required to withdraw or cancel any such form or certificate previously submitted, such Indemnified Person shall promptly notify Anadarko of such fact.

(e) Without prejudice to the survival of any other agreement of Anadarko hereunder, the agreements and obligations of Anadarko and each Indemnified Person contained in this Section 2.14 shall survive the payment in full of principal and interest owing under the WGRAH Loan Agreement.

(f) Any other provision of this Sponsor Payment Guaranty to the contrary notwithstanding, any amounts which are payable by Anadarko under this Section 2.14 shall not also be payable under the Indemnification Sections.

ARTICLE 3
Representations and Warranties

Section 3.01 Representations of Anadarko. Anadarko represents and warrants to Trinity, Pecos and the other Indemnified Persons that:

(a) (i) Anadarko is a corporation duly incorporated and is validly existing and in good standing under the laws of the State of Delaware and (ii) Anadarko is qualified to do business as a foreign corporation and is in good standing in each jurisdiction of the United States in which the ownership of its properties or the conduct of its business requires such qualification and where the failure to so qualify would constitute a Material Adverse Change.

(b) This Sponsor Payment Guaranty been duly authorized, executed and delivered by Anadarko and constitutes a valid and binding agreement of Anadarko, enforceable in accordance with its terms, subject to the effect of applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and equitable principals of general applicability. There are no actions, suits or proceedings pending or, to the knowledge of Anadarko, threatened against Anadarko which purport to affect the legality, validity or enforceability of this Sponsor Payment Guaranty.

(c) The execution, delivery and performance of this Sponsor Payment Guaranty by Anadarko will not violate or conflict with (i) the restated certificate of incorporation or bylaws of Anadarko, (ii) any indenture (including the Public Indenture), loan agreement or other similar agreement or instrument binding on Anadarko, or (iii) any Applicable Law.

(d) On the date of this Sponsor Payment Guaranty there are no actions, suits, proceedings or, to the knowledge of Anadarko, investigations pending or, to the knowledge of Anadarko (with respect to any of the representations in this Section 3.01(d)), threatened against Anadarko before any Governmental Authority as to which, in the opinion of Anadarko, there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to constitute a Material Adverse Change.

(e) The consolidated balance sheets of Anadarko and its consolidated Subsidiaries as of December 31, 2006 and 2007, and the related consolidated statements of income, stockholders’ equity and cash flows for each of the years in the three-year period ended December 31, 2007, audited by KPMG LLP, present fairly, in all material respects, the

consolidated financial position of Anadarko and its consolidated Subsidiaries as of December 31, 2006 and 2007, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2007, in conformity with GAAP applied on a consistent basis.

(f) From December 31, 2007 through the date of this Sponsor Payment Guaranty, there has been no Material Adverse Change.

(g) Neither Anadarko nor any Subsidiary is (i) an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940, or (ii) “holding company” as defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935.

(h) No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Change. The present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans by an amount that could reasonably be expected to be a Material Adverse Change.

(i) None of the other reports, financial statements, certificates or other information made available to Trinity in connection with the negotiation of this Sponsor Payment Guaranty or delivered hereunder (as modified or supplemented by other information so furnished), taken as a whole, contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to projected financial information, Anadarko represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time.

(j) Anadarko has filed all United States Federal income tax returns and all other material tax returns and reports required to be filed (or obtained extensions with respect thereto) and has paid all taxes required to have been paid by it, except (i) taxes the validity of which is being contested in good faith by appropriate proceedings, and with respect to which Anadarko, to the extent required by GAAP, has set aside on its books adequate reserves or (ii) to the extent the failure to do so (individually or collectively) would not reasonably be expected to result in a Material Adverse Change.

(k) No Sponsor Payment Guaranty Event of Default has occurred and is continuing.

(l) Subject to Section 6.14, the obligations of Anadarko under this Sponsor Payment Guaranty (a) are and will at all times be direct and unconditional general obligations of Anadarko and (b) rank and will at all times rank (i) senior in right of payment to any Indebtedness of Anadarko that by its terms is subordinated in right of payment to such obligations and (ii) equal in right of payment to (i.e., pari passu in right of payment with) all other Indebtedness of Anadarko, in each case whether such Indebtedness is now existing or hereafter outstanding.

The foregoing indemnities shall expressly include any indemnified amounts attributable to the ordinary, sole or contributory negligence of any Indemnified Person not constituting gross negligence.
