3.7 Information.

(a) Each Trinity Member acknowledges that, from time to time, it may receive written information from Trinity that is marked as confidential or proprietary, the release of which may be damaging to Trinity. Each Trinity Member shall hold in strict confidence any such information it receives and may not disclose such information to any Person other than another Trinity Member, except for disclosures (i) required to comply with Applicable Law (including applicable stock exchange or quotation system requirements), (ii) to Affiliates, advisers or representatives of the Trinity Member or Persons to which that Trinity Member’s Trinity Membership Interest may be Transferred as permitted by the Trinity Company Agreement, but only if the recipients of such information have agreed to be bound by the provisions of this Section 3.7(a), (iii) of information that a Trinity Member also has received from a source independent of Trinity if such Trinity Member does not have knowledge that such source obtained such information due to a breach of any obligation of confidentiality, (iv) to lenders, accountants and other representatives of the disclosing Trinity Member with a need to know such information, provided, that the disclosing Trinity Member shall be

-14-

responsible for such representatives’ use and disclosure of any such information, (v) of public information, or (vi) in connection with any proposed Transfer of a Trinity Membership Interest in accordance with the Trinity Company Agreement, or in connection with any proposed sale of a Trinity Member’s ultimate parent, to advisers or representatives of the Trinity Member, its direct or indirect parent or Persons to which such interest may be Transferred as permitted by the Trinity Company Agreement, but only if the recipients of such information have agreed in writing to be bound by confidentiality provisions that are no less stringent than those set forth in this Section. Each Trinity Member acknowledges that a breach of the provisions of this Section 3.7(a) may cause irreparable injury to Trinity or another Trinity Member for which monetary damages are inadequate, difficult to compute, or both. Accordingly, each Trinity Member agrees that the provisions of this Section 3.7(a) may be enforced by injunctive action or specific performance, and such Trinity Member hereby waives any requirement to post bond in connection with any injunctive order or order for specific performance. Notwithstanding anything herein to the contrary, the parties and their respective representatives may disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and corporate structure of the transaction and all materials of any kind (including opinions and other tax analyses) that are provided to such party relating to such tax treatment and corporate structure, except where confidentiality is reasonably necessary to comply with securities laws. For this purpose, “corporate structure” is limited to facts relevant to the U.S. federal income tax treatment of the transaction and does not include information relating to the identity of the parties, their affiliates, agents or advisors.

(b) The Trinity Members acknowledge that, from time to time, Trinity may need information from any or all of such Trinity Members for various reasons, including for complying with various federal and state regulations. Each Trinity Member shall provide to Trinity all information reasonably requested by Trinity for purposes of complying with federal or state regulations or for purposes of providing information to federal or state regulatory authorities, in each case within a reasonable amount of time from the date such Trinity Member receives such request; provided, however, that no Trinity Member shall be obligated to provide such information to Trinity to the extent such disclosure (i) could reasonably be expected to result in the breach or violation of any contractual obligation (if a waiver of such restriction cannot reasonably be obtained) or Applicable Law or (ii) involves secret, confidential or proprietary information; and provided, further, however, that in the alternative, any Trinity Member may provide such information directly to such federal or state regulatory authorities.

(c) Notwithstanding anything herein to the contrary, any Trinity Member may disclose to any and all persons, without limitation of any kind, the corporate structure and US tax treatment of the transactions contemplated hereby, and all materials of any kind (including opinions or other tax analyses) relating to such corporate structure and US tax treatment, other than any information for which non-disclosure is reasonably necessary in order to comply with applicable securities law.

-15-

another Trinity Member’s Affiliate) (i) as the result of any act or omission of another Trinity Member or (ii) for Trinity losses, liabilities or obligations (except, in each case, as otherwise expressly agreed to in writing by such Trinity Member).

3.9 Resignation. Each Trinity Member hereby covenants and agrees that it will not resign or withdraw from Trinity as a Trinity Member except (i) with the prior written consent of the Trinity Members or (ii) as a consequence of a Transfer permitted hereunder pursuant to which the Transferee is admitted as a Substituted Member.

3.10 Meetings of Trinity Members.

Notice of any such meeting shall be given to all Trinity Members not less than five Business Days nor more than 30 days prior to the date of such meeting. Trinity Members may vote in person, by proxy or by telephone at such meeting.

(c) Proxy. Any Trinity Member may authorize any Person or Persons to act for it by proxy on all matters in which such Trinity Member is entitled to participate; including waiving notice of any meeting, or voting or participating at a meeting. Every proxy must be signed by such Trinity Member or its attorney-in-fact. No proxy shall be valid after the expiration of 11 months from the date thereof unless otherwise provided in the proxy. Every proxy given by a Trinity Member shall be revocable at the pleasure of the Trinity Member executing it unless otherwise expressly stated in such proxy.

(d) Consents. The approval or consent of any Trinity Member required under the Trinity Company Agreement may, except as expressly provided to the contrary in the Trinity Company Agreement, be given or withheld in the sole and absolute discretion of such Trinity Member. If the Trinity Managing Member receives the necessary approval or consent of the Trinity Members to such action, the Trinity Managing Member shall be authorized and empowered to implement such action without further authorization by the Trinity Members.

(e) Conduct of Meeting. Each meeting of the Trinity Members shall be conducted by the Trinity Managing Member or such other Person as the Trinity Managing Member may appoint pursuant to such rules for the conduct of the meeting as the Trinity Managing Member or such other Person deems appropriate. Any meeting duly called at which the Trinity Managing Member does not appear shall be conducted by the Trinity Class B Member.

(f) Consent in Lieu of Meeting. In the event the consent of any Trinity Member is required for any action to be taken by Trinity, such consent may be given at

-16-

a meeting, which may be conducted by conference telephone call, or provided in writing, executed by the Trinity Member necessary to authorize such action at a meeting.

3.12 Termination of Status as Trinity Member.

(a) A Person shall cease to be a Trinity Member only upon the first to occur of:

(ii) The happening of any of the events specified in Section 18-801(b) of the Act (which shall not relieve such Person from any liability under the Trinity Company Agreement, including liabilities for an unpermitted resignation).

(iii) The involuntary Transfer by operation of Applicable Law of its Trinity Membership Interest (which shall not relieve such Person from any liability under the Trinity Company Agreement, including liabilities for an unpermitted resignation).

(iv) The vote of the Trinity Members required to approve a request by such Trinity Member to withdraw.

(b) The happening of the events set forth in Section 3.12(a) shall not cause a dissolution of Trinity, except as provided in Article XI.

(c) Any debts, obligations, or liabilities in damages to Trinity of any Person who ceases to be a Trinity Member shall be collectible by any legal means and Trinity is authorized, in addition to any other remedies at law or in equity, to apply any amounts otherwise distributable or payable by Trinity to such Person to satisfy such debts, obligations or liabilities.

-17-

(d) Except as otherwise provided in the Trinity Company Agreement, in the event a Person ceases to be a Trinity Member without having Transferred all of its Trinity Membership Interest in accordance with the Trinity Company Agreement (including upon removal or resignation), such Person shall be treated as an unadmitted transferee pursuant to Section 3.5.

ARTICLE IV

(a) The Trinity Class A Member has contributed to Trinity $100,000,000 in cash; and

(b) The Trinity Class B Member has contributed to Trinity $2,200,000,000 in cash.

4.2 Return of Contributions. Other than as set forth in the Trinity Company Agreement, a Trinity Member is not entitled (a) to the return of any part of any Capital Contributions or (b) to be paid interest in respect of either its Capital Account or its Capital Contributions.

A Trinity Member is not required to contribute or to lend any cash or property to Trinity to enable Trinity to return any other Trinity Member’s Capital Contributions.

4.3 Capital Accounts. Trinity shall maintain for each Trinity Member a separate Capital Account in accordance with the rules of Treasury Regulation section 1.704-1(b)(2)(iv) and in accordance with the following provisions:

(a) Each Trinity Member’s Capital Account shall be increased by (i) the amount of all Capital Contributions made to Trinity by such Trinity Member pursuant to the Trinity Company Agreement, (ii) all Profits allocated to such Trinity Member pursuant to Section 5.1, (iii) the amount of any Trinity liabilities assumed by such Trinity Member or that are secured by any Trinity Property distributed to such Trinity Member, and (iv) any items in the nature of income or gain that are specially allocated to such Trinity Member pursuant to the Trinity Company Agreement, and decreased by (x) all Losses allocated to such Trinity Member pursuant to Section 5.1, (y) the amount of any liabilities of such Trinity Member assumed by Trinity or that are secured by any property contributed by such Trinity Member to Trinity, and (z) any items in the nature of expenses or Losses that are specially allocated to such Trinity Member pursuant to the Trinity Company Agreement.

-18-

each was recognized as owning that Trinity Membership Interest, based upon the interim closing of the books method; provided, however, that this allocation must be made in accordance with a method permissible under section 706 of the Code and the Treasury Regulations thereunder.

ARTICLE V

ALLOCATIONS AND DISTRIBUTIONS

5.1 Allocations for Capital Account Purposes. After applying Section 5.1(c) and Section 5.1(d), for purposes of maintaining the Capital Accounts, Trinity’s Profits and Losses or items thereof for each Fiscal Quarter or other period shall be allocated among the Trinity Members as provided herein below.

(a) Profits. Profits shall be allocated as follows:

(i) First, 100% to the Trinity Class B Member in respect of its Trinity Class B Membership Interests, until the amount so allocated is equal to the Cumulative Preferred Return Allocation Amount;

(ii) Second, 100% to the Trinity Members until each Trinity Member has been allocated Profits pursuant to this Section 5.1(a)(ii) (including all Profits allocations made pursuant to this Section 5.1(a)(ii) for prior periods) equal to all Losses previously allocated to such Trinity Member in the reverse order and priority as such Losses were allocated pursuant to Section 5.1(b); and

(iii) Thereafter, the balance, if any, 100% to the Trinity Class A Member in respect of its Trinity Class A Membership Interests.

(b) Losses. Losses shall be allocated as follows:

(i) First, 100% to the Trinity Class A Member in respect of its Trinity Class A Membership Interests, until the Trinity Class A Member’s Capital Account is zero;

-19-

(ii) Second, 100% to the Trinity Class B Member in respect of its Trinity Class B Membership Interests, until the Trinity Class B Member’s Capital Account is zero; and

(iii) Thereafter, the balance, if any, 100% to the Trinity Class A Member in respect of its Trinity Class A Membership Interests.

(c) Special Allocations. All Trinity Expenses associated with Trinity Indemnified Amounts shall be specially allocated to the Trinity Class A Member. All Trinity Expense Reimbursement Income shall be specially allocated to the Trinity Class B Member, provided however, that Trinity Expense Reimbursement Income attributable to amounts received from WGRAH and applied by Trinity as Trinity Indemnified Amounts shall be specially allocated to the Trinity Class A Member.

(d) Other Special Allocations. Notwithstanding any other provision of this Section 5.1, the following special allocations shall be made for such taxable period in the following order and priority:

(i) Trinity Minimum Gain Chargeback. Notwithstanding the other provisions of this Section 5.1, if there is a net decrease in Trinity Minimum Gain during any Trinity taxable period, each Trinity Member shall be allocated items of Trinity income and gain for such taxable period (and, if necessary, subsequent taxable periods) in the manner and amounts provided in Treasury Regulation sections 1.704-2(f)(6) and (g)(2) and section 1.704-2(j)(2)(i), or any successor provisions. For purposes of this Section 5.1(d), each Trinity Member’s Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 5.1(d) with respect to such taxable period (other than an allocation pursuant to Section 5.1(d)(vi) and Section 5.1(d)(vii). This Section 5.1(d)(i) is intended to comply with the Trinity Minimum Gain chargeback requirement in Treasury Regulation section 1.704-2(f) and shall be interpreted consistently therewith.

(ii) Chargeback of Minimum Gain Attributable to Member Nonrecourse Debt. Notwithstanding the other provisions of this Section 5.1 (other than Section 5.1(d)(i)), except as provided in Treasury Regulation section 1.704-2(i)(4), if there is a net decrease in Member Nonrecourse Debt Minimum Gain during any Trinity taxable period, any Trinity Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Trinity income and gain for such taxable period (and, if necessary, subsequent taxable periods) in the manner and amounts provided in Treasury Regulation sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 5.1(d), each Trinity

-20-

Member’s Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 5.1(d), other than Section 5.1(d)(i) and other than an allocation pursuant to Section 5.1(d)(vi) and Section 5.1(d)(vii), with respect to such taxable period. This Section 5.1(d)(ii) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii) Qualified Income Offset. In the event any Trinity Member unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation section 1.704-1(b)(2)(ii)(d)(4) through (6), items of Trinity income and gain shall be specially allocated to such Trinity Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided, that, an allocation pursuant to this Section 5.1(d)(iii) shall be made only if and to the extent that such Trinity Member would have a deficit in such Trinity Member’s Adjusted Capital Account after all other allocations provided in this Article V have been tentatively made as if this Section 5.1(d)(iii) were not a part of the Trinity Company Agreement. This Section 5.1(d)(iii) is intended to be a “qualified income offset” as that term is used in Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(iv) Stop Loss. No amount of Loss shall be allocated pursuant to Section 5.1(b) to the extent that such allocation would cause any Trinity Member to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account). All Losses in excess of the limitation set forth in the preceding sentence shall be allocated among such other Trinity Members, who have positive Adjusted Capital Account balances, in proportion to their respective Trinity Membership Interests until each Trinity Member’s Adjusted Capital Account balance is reduced to zero. Thereafter, any remaining Loss shall be allocated to the Trinity Members in proportion to their relative interests in Trinity as required by Section 704(b) of the Code.

(v) Gross Income Allocations. In the event any Trinity Member has a deficit balance in its Adjusted Capital Account at the end of any Trinity taxable period in excess of the sum of (A) the amount such Trinity Member is obligated to restore pursuant to any provision of the Trinity Company Agreement and (B) the amount such Trinity Member is deemed obligated to restore pursuant to Treasury Regulations sections 1.704-2(g) and 1.704-2(i)(5), such Trinity Member shall be specially allocated items of Trinity gross income and gain in the amount of such excess as quickly as possible; provided, that, an allocation pursuant to this Section 5.1(d)(v) shall be made only if and to the extent that such Trinity Member would have a deficit balance in its Adjusted Capital Account after all other allocations provided in this Section 5.1 have been tentatively made as if Section 5.1(d)(iii) and this Section 5.1(d)(v) were not in the Trinity Company Agreement.

-21-

(vi) Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Trinity Class A Members in accordance with their respective Trinity Class A Membership Interests. If the Trinity Managing Member determines that Trinity’s Nonrecourse Deductions should be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under section 704(b) of the Code, the Trinity Managing Member is authorized, upon notice to the Trinity Members, to revise the prescribed ratio to the numerically closest ratio which does satisfy such requirements.

(vii) Member Nonrecourse Deductions. Member Nonrecourse Deductions for any taxable period shall be allocated 100% to the Trinity Member that bears the Economic Risk of Loss with respect to such Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulation section 1.704-2(i). If more than one Trinity Member bears the Economic Risk of Loss with respect to a Member Nonrecourse Debt, such Member Nonrecourse Deductions attributable thereto shall be allocated between or among such Trinity Members in accordance with the ratios in which they share such Economic Risk of Loss.

(viii) Nonrecourse Liabilities. For purposes of Treasury Regulation section 1.752-3(a)(3), the Trinity Members agree that Nonrecourse Liabilities of Trinity in excess of Trinity Minimum Gain shall be allocated among the Trinity Class A Members in accordance with their respective Trinity Class A Membership Interests.

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

(x) Curative Allocation.

(A) Notwithstanding any other provision of this Section 5.1, other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of income, gain, loss or deduction allocated to each Trinity Member pursuant to the Required Allocations

-22-

and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Trinity Member under the Agreed Allocations had the Required Allocations and the related Curative Allocations not otherwise been provided in this Section 5.1. Notwithstanding the preceding sentence, Required Allocations relating to (1) Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Trinity Minimum Gain and (2) Member Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Member Nonrecourse Debt Minimum Gain. Allocations pursuant to this Section 5.1(d)(x)(A) shall only be made with respect to Required Allocations to the extent the Trinity Managing Member reasonably determines that such allocations will otherwise be inconsistent with the economic agreement among the Trinity Members. Further, allocations pursuant to this Section 5.1(d)(x)(A) shall be deferred with respect to allocations pursuant to clauses (1) and (2) hereof to the extent the Trinity Managing Member determines that such allocations are likely to be offset by subsequent Required Allocations.

(B) The Trinity Managing Member shall, with respect to each taxable period, (1) apply the provisions of Section 5.1(d)(x)(A) in whatever order is most likely to minimize economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 5.1(d)(x)(A) among the Trinity Members in a manner that is likely to minimize such economic distortions.

5.2 Allocations for Tax Purposes. Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Trinity Members in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 5.1.

5.3 Distributions.

(a) In addition to any distributions required under Section 18-607 of the Act, Section 5.3(b), Section 5.4, and Section 5.7(b), on each Payment Date Trinity shall make a distribution at least equal to the following:

(i) First, to the Trinity Class B Member in respect of its Trinity Class B Membership Interest up to the amount of the Cumulative Preferred Return Distribution Amount; and

(ii) Second, at the election of the Trinity Managing Member, any Available Cash to the Trinity Class A Member in respect of its Trinity Class A Membership Interest.

(b) Notwithstanding the foregoing, any Early Retirement Proceeds shall be immediately distributed to the Trinity Class B Member upon their receipt. All of such

-23-

funds shall be distributed to the Trinity Class B Member in respect of its Trinity Class B Membership Interest and (i) the Cumulative Preferred Return Distribution Amount shall be reduced by the amount of such distribution and (ii) if the funds distributed are in excess of the Cumulative Preferred Return Distribution Amount, the Unrecovered Capital shall be reduced by such excess. The Trinity Class B Member will provide notice of the Interest Rate as of the expected date of payment of such Early Retirement Proceeds and any Trinity Expenses relating to the receipt of such Early Retirement Proceeds in accordance with Section 5.6 of the Trinity Company Agreement within 1 Business Day following receipt by the Trinity Class B Member of notice from the Trinity Managing Member that a prepayment is being made pursuant to Section 2.05 of the WGRAH Loan Agreement.

5.4 Special Distributions.

(a) All payments received by Trinity from WGRAH pursuant to Section 2.09 of the WGRAH Loan Agreement on account of Trinity Expenses and not applied by Trinity to pay Trinity Indemnified Amounts shall be distributed promptly (and in no event later than the next succeeding Business Day) after receipt of such amounts to the Trinity Class B Member.

(b) The distributions required pursuant to Section 5.7(b) shall be made on the date set forth in such section.

5.5 Making of Payments; Etc. All payments to the Trinity Members pursuant to any provision of the Trinity Company Agreement shall be made in immediately available funds no later than 12:00 noon (New York City time) on the day of such payment, and, at the time of the making of any such payment, the Trinity Managing Member shall provide (or shall cause the Trinity Custodian to provide) to the Trinity Class B Member and the Trinity Custodian a notice identifying the nature of such payment, the Section or Sections of the Trinity Company Agreement pursuant to which it is being made and the amount being distributed or paid pursuant to, each such Section. The Trinity Managing Member or, after the Liquidation Start Date, the Liquidator, shall notify the Trinity Custodian of the amount of each such payment hereunder, the calculation thereof, in reasonable, detail, and the Section of the Trinity Company Agreement pursuant to which such payment is to be made no later than 12:00 noon (Wilmington, Delaware time) on the second Business Day prior to any such payment pursuant to Section 5.3 and to the extent practicable with respect to each payment pursuant to Section 5.4. To the extent that any Preferred Return accrues but is unpaid during any Payment Period, such unpaid amount shall accrue interest at a rate per annum equal to the Interest Rate plus 2%.

5.6 Determination of the Preferred Return. The Trinity Class B Member shall notify the Trinity Managing Member or the Liquidator, as the case may be, on behalf of Trinity, and shall notify WGRAH on behalf of Trinity under the WGRAH Loan Agreement, (x) three Business Days prior to the Payment Date for each Payment Period (in respect of any payments to be made under Section 5.3) and (y) no later than 10:00 am (New York City time) on the date of any other payment under Article V, of the Interest Rate applicable to such Payment Period (or portion thereof). Each determination by the Trinity Class B Member of the Interest Rate shall be conclusive and binding for all purposes, absent manifest error, and shall be accompanied by such supporting documentation as to the determination of the Interest Rate as the Trinity Managing Member, or the Liquidator, as the case may be, or WGRAH may reasonably request.

-24-

5.7 Preferred Return Reset.

(a) Prior to the 5th anniversary of the Effective Date (and, in the event of agreement, on each 5th successive anniversary thereafter) (each such date, a “Reset Date”), the Trinity Members shall meet to discuss amendments to the definitions of “Preferred Return” and related terms. The Trinity Class A Member shall propose whether to maintain the then-effective definitions of “Preferred Return” and related terms or to make adjustments thereto. The Trinity Class B Member shall determine, in its sole discretion, whether or not to accept the proposal made by the Trinity Class A Member (which determination may be made by the Trinity Class B Member regardless of whether or not the Trinity Class A Member proposes any changes to the definition of “Preferred Return” and related terms). If the Trinity Class B Member does not accept such proposal prior to the Reset Date, such failure shall constitute a Notice Event.

(b) If the Trinity Class B Member does not agree (in its sole discretion) to the Trinity Class A Member’s proposal as set forth in Section 5.7(a) before the third month prior to the Reset Date, Trinity will engage an underwriter or other sales agent, reasonably acceptable to the Trinity Class A Member (the “Sales Agent”), designated by the Trinity Class B Member to effect a sale of the WGRAH Note. Trinity and the Trinity Managing Member will, and the Managing Member will cause Anadarko to, use their best efforts to assist the Sales Agent in the conduct of such sale. The Sales Agent will be entitled to reset the interest rate on the WGRAH Note to a level sufficient to enable the sale of the WGRAH Note for no less than the sum of (i) all outstanding principal, accrued and unpaid interest, and accrued and unpaid expenses and fees thereunder, plus (ii) all fees including reasonable costs and expenses (including reasonable attorneys’ fees and the fees and expenses of the Sales Agent) and all other unpaid Trinity Expenses and Trinity Expenses reasonably anticipated to become due, minus (iii) the current value of any Permitted Assets then owned by Trinity other than those arising under or related to the WGRAH Loan Documents (such sum being the “Minimum Sale Proceeds”). Unless the Trinity Class B Membership Interest is previously retired or purchased in accordance with Article X of this Trinity Company Agreement or the WGRAH Note is purchased in accordance with the Sponsor Note Option Agreement, the Sales Agent shall sell the WGRAH Note for cash consideration of at least the Minimum Sale Proceeds as promptly as practicable after its appointment (and in no event later than the Reset Date). No sale of the WGRAH Note for either (A) any consideration other than cash, or (B) total consideration less than the Minimum Sale Proceeds may be made by the Sales Agent other than with the prior consent of the Trinity Class B Member in its sole discretion. The sum of (I) the proceeds of any sale pursuant to this Section 5.7(b) and (II) the proceeds of all other Permitted Assets then owned by Trinity shall immediately be used by Trinity to make a distribution to the Trinity Class B Member in an amount equal to the sum of all (x) Unrecovered Capital plus (y) the Cumulative Preferred Return Distribution Amount at the time of distribution, plus (z) all Trinity Expenses then unpaid and that will be incurred in connection with such distribution.

-25-

(c) Within ten days following an ASCE Trigger Date, the Trinity Class B Member may (in its sole discretion) propose to the Trinity Class A Member an adjustment to the then-effective definitions of “Preferred Return” and related terms (the date when such proposal is made to the Trinity Class A Member being the “Reset Proposal Date”). If the Trinity Class B Member makes such a proposal, then the Trinity Class A Member shall have 5 days following the Reset Proposal Date to accept or reject such proposal in its sole discretion. If either (i) the Trinity Class B Member fails to make such a proposal within ten days following an ASCE Trigger Date, (ii) the Trinity Class B Member notifies the Trinity Class A Member prior to the tenth day following an ASCE Trigger Date that it will not be making such a proposal, (iii) the Trinity Class A Member rejects such proposal, or (iv) the Trinity Class A Member fails to accept such proposal by the fifth day following the Reset Proposal Date, then upon such occurrence Trinity shall engage a Sales Agent designated by the Trinity Class B Member, to effect a sale of the WGRAH Note. Trinity and the Managing Member will, and the Managing Member will cause Anadarko to, use their best efforts to assist the Sales Agent in the conduct of such sale. The Sales Agent will be entitled to reset the interest rate on the WGRAH Note to a level sufficient to enable the sale of the WGRAH Note for no less than the Minimum Sale Proceeds. Unless the Trinity Class B Membership Interest is previously retired or purchased in accordance with Article X of this Trinity Company Agreement, the Sales Agent shall sell the WGRAH Note for cash consideration of at least the Minimum Sale Proceeds as promptly as practicable after its appointment (and in no event later than the date that is 60 days following the ASCE Trigger Date). No sale of the WGRAH Note for either (A) any consideration other than cash, or (B) total consideration less than the Minimum Sale Proceeds may be made by the Sales Agent other than with the prior consent of the Trinity Class B Member in its sole discretion. The sum of (I) the proceeds of any sale pursuant to this Section 5.7(c) and (II) the proceeds of all other Permitted Assets then owned by Trinity shall immediately be used by Trinity to make a distribution to the Trinity Class B Member in an 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. Failure to sell the WGRAH Note for the Minimum Sale Proceeds by the date that is 60 days following the ASCE Trigger Date will be a Notice Event.

7.7 Procedural Requirements.

(a) Notice of Claims.

-32-

Indemnitor under this Article VII, notify such Indemnitor of the commencement of such Trinity Indemnified Proceeding or of such incurrence or realization, enclosing a copy of all relevant documents, including all papers served and claims made, but the failure so to notify such Indemnitor promptly of any such Trinity Indemnified Proceeding or incurrence or realization shall not relieve (i) such Indemnitor from any liability that it may have to such Indemnified Person under this Article VII or otherwise, except, as to such Indemnitor’s liability under this Article VII, to the extent, but only to the extent, that such Indemnitor 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 Trinity Indemnified Proceeding shall be brought against any Indemnified Person and it shall notify the relevant Indemnitor of the commencement thereof, such Indemnitor shall be entitled to participate in, and to assume the defense of, such Trinity Indemnified Proceeding with counsel reasonably satisfactory to such Indemnified Person, and after notice from such Indemnitor to such Indemnified Person of such Indemnitor’s election so to assume the defense thereof and the failure by such Indemnified Person to object to such counsel within ten Business Days following its receipt of such notice, such Indemnitor 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. Such Indemnified Person shall have the right to employ its counsel in any such Trinity Indemnified Proceeding, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless:

(i) the employment of counsel by such Indemnified Person at the expense of such Indemnitor has been authorized in writing by such Indemnitor (which authorization shall not be unreasonably withheld or delayed);

(ii) such Indemnified Person shall have reasonably concluded in its good faith (which conclusion shall be determinative unless a court determines that conclusion was not reached reasonably and in good faith) that there is or may be a conflict of interest between such Indemnitor and such Indemnified Person in the conduct of the defense of such Trinity Indemnified Proceeding or that there are or may be one or more different or additional defenses, claims, counterclaims, or causes of action available to such Indemnified Person (it being agreed that in any case referred to in this clause (ii), such Indemnitor shall not have the right to direct the defense of such Trinity Indemnified Proceeding on behalf of the Indemnified Person);

(iii) such Indemnitor shall not have employed counsel reasonably acceptable to the Indemnified Person, to assume the defense of such Trinity Indemnified Proceeding within a reasonable time after notice of the commencement thereof (provided, however, that this clause (iii) shall not constitute a waiver of any conflict of interest which may arise with respect to any such counsel); or

-33-

(iv) any counsel employed by such Indemnitor shall fail to timely commence or maintain the defense of such Trinity Indemnified Proceeding, in each of which cases the fees and expenses of counsel for such Indemnified Person shall be at the expense of such Indemnitor; provided, that without the prior written consent of such Indemnified Person, such Indemnitor shall not settle or compromise, or consent to the entry of any judgment in, any pending or threatened Trinity 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 Trinity Indemnified Proceeding in respect of which any payment would result hereunder or under the other Transaction Agreements without the prior written consent of such Indemnitor, such consent not to be unreasonably withheld or delayed. Only one counsel shall be retained by all Indemnified Persons with respect to any Trinity Indemnified Proceeding, unless counsel for any Indemnified Person reasonably concludes in good faith (which conclusion shall be determinative unless a court determines that conclusion was not reached reasonably and in good faith) that there is or may be a conflict of interest between such Indemnified Person and one or more other Indemnified Persons in the conduct of the defense of such Trinity Indemnified Proceeding or that there are or may be one or more different or additional defenses, claims, counterclaims, or causes of action available to such Indemnified Person (it being agreed that in any case referred to in this sentence such Indemnified Person may retain separate counsel together with all other Indemnified Persons subject to the same conflict of interest or sharing such additional defenses, claims, counterclaims or causes of action).

The foregoing Indemnities shall expressly include any Trinity Indemnified Amounts attributable to the ordinary, sole or contributory negligence of any Indemnified Person.

ARTICLE XI

DISSOLUTION, LIQUIDATION, AND TERMINATION

11.1 Liquidation.

(a) Liquidating Events. Trinity shall dissolve and commence winding up and liquidating upon, and only upon, the occurrence of a Liquidating Event.

(b) Termination Notice. At any time on or after the occurrence and during the continuance of any Notice Event, the Trinity Class B Member may elect to cause such Notice Event to result in a Termination Event by delivering to the Managing Member a notice (a “Termination Notice”) of such election. Such Termination Notice shall be effective on the Business Day it is delivered (unless stated to be effective on any other day after the day of delivery) to the Managing Member (or if such delivery day or such other day is not a Business Day, the immediately following Business Day) (the date of such effectiveness being the “Termination Notice Effective Date”). Any such Termination Notice may be rescinded by the Trinity Class B Member giving such Termination Notice prior to the Termination Notice Effective Date by delivery of a rescission notice to the Managing Member.

11.2 Winding Up.

(a) Distribution of Assets. Upon the occurrence of a Liquidating Event, Trinity shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Trinity Members, and no Trinity Member shall take any action with respect to Trinity that is inconsistent with the winding up of Trinity’s business and affairs; provided, that all covenants contained in the Trinity Company Agreement and obligations provided for in the Trinity Company Agreement shall continue to be fully binding upon the Trinity Members until the Trinity Property has been distributed pursuant to this Section 11.2 and the Certificate has been cancelled pursuant to the Act. The Liquidator shall be responsible for overseeing the winding up and dissolution of Trinity (including taking any actions required by Section 11.9), shall take full account of Trinity’s liabilities and the Trinity Property, and, subject to Section 11.2(c), shall cause the Trinity Property or the proceeds from the disposition thereof and the proceeds from the repayment of the WGRAH Note, to the extent sufficient therefor, to be applied and distributed, to the maximum extent permitted by Applicable Law, in the following order:

(i) First, as provided in Section 18-804(a)(1) of the Act; and

(ii) Second, the balance, if any, to the Trinity Members in an amount equal to their Capital Account balances, after giving effect to all contributions, distributions, and allocations made for all periods through the end of the Liquidation Period; provided, that, at the option of the Trinity Class B Member, cash (as opposed to other property) shall be first applied and distributed to the Trinity Class B Member and second to the Trinity Class A Member.

-39-

(b) Reserves. Subject to Section 11.2(c), in the reasonable good faith discretion of the Liquidator, with the consent of the Trinity Class B Member, a portion (determined in the manner provided below) of the distributions that would otherwise be made to the Trinity Members pursuant to Section 11.2(a) may be:

(i) Distributed to a trust established solely for the purposes of liquidating Trinity Property, collecting amounts owed to Trinity, and paying any reasonably anticipated contingent or unforeseen liabilities or obligations of Trinity arising out of or in connection with Trinity. The assets of any such trust shall be distributed from time to time, in the reasonable good faith discretion of the Liquidator, in the same order of priority as the amount distributed to such trust by Trinity would otherwise have been distributed to the Trinity Members pursuant to Section 11.2(a); or

(ii) Withheld to provide a reasonable reserve for reasonably anticipated Trinity liabilities (contingent or otherwise) and to allow for the collection of the unrealized portion of any installment obligations owed to Trinity; provided, that such withheld amounts shall be distributed pursuant to Section 11.2(a) as soon as practicable.

The portion of the Distributions that would otherwise have been made to each of the Trinity Members that is instead distributed to a trust pursuant to Section 11.2(b)(i) or withheld to provide a reserve pursuant to Section 11.2(b)(ii) shall be determined in the same manner as the expense or deduction that would have been allocated if Trinity had realized an expense equal to such amounts immediately prior to a distribution being made pursuant to Section 11.2(a).

(c) Distribution Upon an Anadarko Credit Event. In the event that a Liquidating Event occurs as the result of an Anadarko Credit Event, (i) the WGRAH Note and the WRGAH Advance Documents will be immediately distributed to the Trinity Class B Member, (ii) all other Trinity Property will be placed into a trust in accordance with the procedures set forth in Section 11.2(b), and (iii) Trinity shall grant the Trinity Class B Member a security interest in the trust and the proceeds therefrom to secure Trinity’s obligation to make payments to the Trinity Class B Member pursuant to Section 11.2(a), to the extent that such payments are necessary following liquidation by the Trinity Class B Member of the Trinity Property distributed to it pursuant to Section 11.2(c)(i).

11.3 Restoration of Deficit Capital Accounts. Notwithstanding anything in the Trinity Company Agreement to the contrary, if a Liquidating Event has occurred and Trinity is wound up in accordance with Section 11.2, no Trinity Member shall be obligated to make any Capital Contributions to Trinity in respect of a deficit balance in its Capital Account, and such deficit shall not be considered to be a debt owed to Trinity or to any other Person for any purpose whatsoever.

-40-

11.4 Rights of Members. Each Trinity Member shall look solely to the Trinity Property for the return of its Capital Contribution and, except as otherwise provided in Section 11.10, shall have no right or power to demand or receive property other than cash, from Trinity.

11.5 Occurrence of Liquidating Event.

(a) A “Liquidating Event” will occur (the date of such occurrence being the “Liquidation Start Date”) on the earlier of (i) first Business Day occurring immediately after the expiration of the Purchase Option Period following the occurrence of a Termination Event or (ii) the occurrence of any event which requires dissolution of Trinity under the Act.

(b) The Trinity Members hereby agree that Trinity shall not be dissolved or required to be wound up notwithstanding the occurrence of an event that caused the last Trinity Member to cease to be a Trinity Member, if within ninety (90) days after such event the Personal Representative (as defined in the Act) of such last remaining Trinity Member agrees in writing to continue the business of Trinity and to the admission, effective as of the date of such event, of one or more additional Trinity Members.

11.6 Allocations and Distributions During Period of Liquidation. During the Liquidation Period, the Trinity Members shall continue to share Profits, Losses and other items of Trinity income, gain, loss or deduction in the manner provided in Article V and Preferred Return, distributions and other payments shall continue to be made as set forth in Article V. In addition, the Liquidator, in its sole discretion, may make cash distributions to the Trinity Class B Member at any time.

11.7 Character of Liquidating Distributions. All payments made in liquidation of Trinity Membership Interests shall be made in exchange for the interest of such Trinity Member in Trinity Property pursuant to Section 736(b)(1) of the Code, including the interest of such Trinity Member in Trinity goodwill.

11.8 The Liquidator.

(a) Definition. The “Liquidator” shall mean (i) in the event that a liquidation of Trinity results from a Termination Event described in clause (d) of the definition of Termination Event, the Trinity Class A Member or any other Affiliate of Anadarko appointed as Liquidator by the Trinity Class A Member; provided, however, that, if the Collection Date does not occur within 30 days after the Liquidation Start Date, then the Liquidator shall be appointed by the Trinity Class B Member upon written notice to the Trinity Class A Member and (ii) in any other circumstance, any other Person appointed as Liquidator by the Trinity Class B Member.

The Trinity Class B Member (or the Trinity Class A Member if it may then appoint the Liquidator) may appoint an appointee to be Liquidator prior to the Liquidation Start Date by delivering written notice of such appointment to the other Trinity Members. Any such appointment may be subsequently withdrawn by similar written notice.

-41-

The Liquidator shall have the rights set forth in Section 18-803(b) of the Act and exclusively shall have the rights, power and authority of the Managing Member necessary or appropriate in its discretion to effect the dissolution, winding up and liquidation of Trinity. In furtherance of the foregoing and not as a limitation, the Liquidator shall have the authority to enter into any agreement or incur obligations on behalf of Trinity to the extent necessary, in its sole judgment, to facilitate the liquidation of Trinity and the marshalling or collection of its assets, including, without limitation, the authority to engage sales agents or other professional advisors on market terms. The actions of the Liquidator shall for all purposes be the actions of Trinity.

(b) Fees and Expenses. Trinity is authorized to pay a reasonable fee to the Liquidator for its services performed pursuant to this Article XI and to reimburse the Liquidator for its reasonable costs and expenses incurred in performing those services, including costs and expenses of counsel, accountants, sales agents and other professional advisors to the Liquidator.

14.2 Waivers. Neither action taken (including any investigation by or on behalf of any Party) nor inaction pursuant to the Trinity Company Agreement, shall be deemed to constitute a waiver of compliance with any representation, warranty, covenant or agreement contained herein by the Party not committing such action or inaction. A waiver by any Party of a particular right, including breach of any provision of the Trinity Company Agreement, shall not operate or be construed as a subsequent waiver of that same right or a waiver of any other right.

14.3 Binding Effect. Except as otherwise provided in the Trinity Company Agreement, every covenant, term and provision of the Trinity Company Agreement shall be binding upon the Trinity Members and inure to the benefit of the Trinity Members and each Indemnified Person and their respective permitted successors, transferees, and assigns (including any assignee for security purposes or Person holding a security interest).

(a) THE TRINITY COMPANY AGREEMENT HAS BEEN EXECUTED AND DELIVERED AND SHALL BE CONSTRUED, INTERPRETED AND GOVERNED PURSUANT TO AND IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO ANY CONFLICT OF LAWS PRINCIPLES WHICH, IF APPLIED, MIGHT PERMIT OR REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

(b) In the event of a direct conflict between the provisions of the Trinity Company Agreement and any mandatory provision of the Act or Applicable Law, the applicable provision of the Act or other Applicable Law, as the case may be, shall control. If any provision of this Trinity Company Agreement, or the application thereof to any Person or circumstance, is held invalid or unenforceable to any extent, the

-46-

remainder of the Trinity Company Agreement and the application of that provision to other Persons or circumstances shall not be affected thereby and that provision shall be enforced to the greatest extent permitted by the Act or other Applicable Law, as the case may be. The preceding sentence of this Section shall be of no force or effect if the consequence of enforcing the remainder of the Trinity Company Agreement without such illegal or invalid term or provision would be to cause any Trinity Member to lose the benefit of its economic bargain.

Each Trinity Member hereby agrees that the Trinity Company Agreement constitutes adequate notice of all such provisions.

14.9 Checks, Notes and Contracts. Checks and other orders for the payment of money shall be signed by such Person or Persons as the Trinity Managing Member shall from time to time determine. To the extent permitted by the Trinity Company Agreement, contracts and other instruments or documents may be signed in the name of Trinity by the Trinity Managing Member. Checks and other orders for the payment of money made payable to Trinity may be endorsed for deposit to the credit of Trinity, with a depositary authorized by resolution of the Trinity Members, by such Persons as the Trinity Members may from time to time by resolution determine.

14.10 No Third Party Beneficiaries. The provisions of the Trinity Company Agreement are for the exclusive benefit of the Trinity Members and their respective successors and permitted assigns and, solely with respect to Article VII, the Indemnified Persons described therein. Except for the foregoing, the Trinity Company Agreement is not intended to benefit or create rights in any other Person.
