Decommissioning Trust Agreement as decommissioning trustee for Palo Verde Unit 3

This Decommissioning Trust Agreement (the “Agreement”), to be effective as of April 1, 2006 (the “Effective Date”), between Wells Fargo Bank, National Association, a national banking association (“Decommissioning Trustee”) and El Paso Electric Company, a Texas corporation (“El Paso”).

The Nuclear Regulatory Commission (“NRC”), an agency of the United States of America, pursuant to the Atomic Energy Act of 1954, as amended, and the Energy Reorganization Act of 1974, has promulgated regulations codified in Title 10, Chapter 1 of the Code of Federal Regulations, Part 50, as amended. These regulations, applicable to El Paso, require that each holder of a license issued pursuant thereto must provide assurance that funds will be available for Decommissioning.

El Paso and others entered into the Arizona Nuclear Power Project Participation Agreement executed as of August 23, 1973 (the “ANPP Participation Agreement”). Amendment 13 to the ANPP Participation Agreement, effective June 15, 1991, requires El Paso to establish and maintain funds for the accumulation, over a period not in excess of the remaining term of the operating license for Unit 3 and the period thereafter until completion of Decommissioning, of funds sufficient to pay Decommissioning Cost.

In addition, El Paso is required by the Public Utility Commission of Texas (“PUCT”), the New Mexico Public Regulation Commission (“NMPRC”), the Federal Energy Regulatory Commission and the Nuclear Regulatory Commission to establish a source of funds to pay for Decommissioning.

Under Applicable Tax Law, certain federal income tax benefits are available to El Paso from establishing and making contributions to a “Nuclear Decommissioning Reserve Fund” for Unit 3. In order to satisfy its obligations under the ANPP Participation Agreement, to comply with the requirements of the governmental authorities referred to above, and to obtain such federal income tax benefits, on December 1, 1987, El Paso entered into a Decommissioning Trust Agreement, which was amended by Amendment No. 1 dated September 1, 1991 (the “Original Agreement”), creating two decommissioning trust funds to provide external funds for Decommissioning, for purposes of this Agreement designated as the Decommissioning Trust Fund and the Second Fund. The Decommissioning Trust Fund is intended at all times to qualify as a “Nuclear Decommissioning Reserve Fund” under Applicable Tax Law.

On January 9, 1996, in Cause No. 92-10148-FM, styled In re: El Paso Electric Company, the United States Bankruptcy Court for the Western District of Texas (Austin Division) entered an order confirming the Fourth Amended Plan of Reorganization of El Paso (the “Plan”). In accordance with the Plan, which became effective on February 12, 1996, El Paso and Decommissioning Trustee restated and amended the Original Agreement to ensure that the Decommissioning Trust Fund and the Second Fund would continue to be held, managed and distributed, without interruption, in accordance with the terms of the Original Agreement, Applicable Law, and Applicable Tax Law.

This Agreement, in turn, amends and restates the Original Agreement, as restated and amended effective February 12, 1996, and as further restated and amended effective December 24, 2003, to read in its entirety as follows and continues the Decommissioning Trust Fund and the Second Fund.

Therefore, in consideration of the foregoing premises, the acceptance by Decommissioning Trustee of the trusts created, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto restate and amend the Original Agreement, as restated and amended effective February 12, 1996, as follows:

SECTION 1. Definitions; References to Sections. All capitalized terms used in this Agreement and not otherwise defined herein shall have the meanings set forth in Appendix A hereto. Unless otherwise stated, references to a “Section” are to a section of this Agreement.

SECTION 2. Creation of Trust Funds. El Paso has established and hereby confirms the establishment with Decommissioning Trustee of the Decommissioning Trust Fund and the Second Fund (each a “Fund” and together the “Funds”). Each Fund shall include: (A) all cash and investments thereof, as more specifically described in Section 7; (B) all dividends, interest, cash, instruments, and other property from time to time received, receivable, or otherwise distributed or distributable in respect of or in exchange for any or all such investments; (C) all rights and privileges with respect to such investments; and (D) all proceeds of any of the foregoing and any property of any character whatsoever into which any of the foregoing may be converted.

SECTION 3. Purpose of Trust Funds; Tax Qualification. The Funds are for the accumulation and funding of amounts to pay costs, liabilities, and expenses of Decommissioning, including the accumulation, over a period not in excess of the remaining term of the operating license for Unit 3 and the period thereafter until completion of Decommissioning, of amounts which are sufficient to pay Decommissioning Cost. The Decommissioning Trust Fund, but not the Second Fund, is intended at all times to qualify as a “Nuclear Decommissioning Reserve Fund” under Applicable Tax Law. El Paso and the applicable Fiduciary Investment Manager(s), if any, and Decommissioning Trustee (but with respect to Decommissioning Trustee only as to those assets of the Funds that are not under the direction of a Fiduciary Investment Manager) shall seek to obtain the best possible tax treatment of amounts collected for nuclear plant decommissioning; and in this regard, El Paso and the applicable Fiduciary Investment Manager(s), if any, and Decommissioning Trustee (but with respect to Decommissioning Trustee only as to those assets of the Funds that are not under the direction of a Fiduciary Investment Manager) shall take maximum advantage of tax deductions and credits when it is consistent with sound business practices to do so. The assets of the Decommissioning Trust Fund must be used as authorized by section 468A of the Code and shall be used exclusively:

(A) subject to the limitations and conditions of Section 9, to satisfy, in whole or in part, El Paso’s obligation to pay for Decommissioning;

(B) subject to the limitations and conditions of Section 8, to pay Expenses; and

(C) to the extent not currently required for the uses described in (A) and (B) above, and subject to the limitations and conditions of Section 7, for investment in Qualified Investments.

The Funds shall be used exclusively for Decommissioning of Unit 3. This Agreement may not be amended so as to violate section 468A of the Code or the regulations thereunder.

SECTION 4. Declaration and Acceptance of Trust. Decommissioning Trustee accepts the trusts created hereby and declares that it will hold and administer all estate, right, title, and interest in and to each Fund upon the trusts set forth herein, but only on the terms of this Agreement, and agrees to receive and disburse all moneys and investments constituting any part of each Fund in accordance with this Agreement. No implied duties or obligations shall be read into this Agreement against Decommissioning Trustee. Decommissioning Trustee shall not commit any act, enter into any transaction, or permit any act or transaction to occur that is an “act of self dealing” between the Decommissioning Trust Fund and “a disqualified person” as those terms are defined by Applicable Tax Law, and, if such an act occurs, Decommissioning Trustee shall promptly take all necessary steps to correct it as soon as it has knowledge of the occurrence.

SECTION 5. Ownership of Funds. Not in limitation of its fiduciary duty hereunder, title to any and all property held in each Fund shall be held by Decommissioning Trustee in its name as trustee as owner of record. At all times, Decommissioning Trustee shall follow the directives of (A) the applicable Fiduciary Investment Manager, if any, with respect to exercising any and all corresponding voting, consensual, and other rights accruing to the owner of such property in connection with such property, and, except as provided in this subsection 5.(A), (B) El Paso with respect to exercising any and all such voting, consensual, and other rights. Decommissioning Trustee shall have the right, in its name, as trustee upon prior written notice to El Paso, to settle, compromise, prosecute, or defend any action, claim, or proceeding with respect to any and all property held in each Fund. Subject to the provisions of this Agreement, Decommissioning Trustee may sell, assign, endorse, pledge, transfer, and make any agreement respecting, or otherwise deal with, any and all property held in each Fund; provided, however, that except as required by Section 7, nothing herein contained shall be construed as requiring or obligating Decommissioning Trustee to make any inquiry as to the nature or sufficiency of any payment received by it, to present or file any claim or notice, or to take any action with respect to any of the property held in each Fund. It is not the duty of Decommissioning Trustee or a Fiduciary Investment Manager to ensure that the Funds are adequate to pay for Decommissioning.

SECTION 6. Payments into the Funds. From time to time, but not less than quarter-annually, El Paso shall pay amounts into one or both of the Funds. El Paso may deposit all or any part of any payment entirely into the Decommissioning Trust Fund, entirely into the Second Fund, or partly into each in whatever proportion El Paso shall determine in its discretion; except that, if a deduction is allowed under Applicable Tax Law for payments into the Decommissioning Trust Fund, El Paso shall not make, and Decommissioning Trustee shall not accept, any payment into such Fund unless such payment (a) is in cash, to the extent Applicable Tax Law requires the payment to be in cash, and (b) complies with the amount limitation imposed by Applicable Tax Law and a deduction pursuant to Applicable Tax Law is allowed for the entire payment. Decommissioning Trustee may accept from El Paso, as proof that these

conditions are satisfied, a certificate executed by El Paso as to compliance with the amount limitation and deductibility of such payment, and, unless Decommissioning Trustee has actual knowledge to the contrary, Decommissioning Trustee may rely on such certificate without further inquiry or verification.

(A) Decommissioning Trustee. Any amounts held by Decommissioning Trustee in each Fund shall be invested and reinvested by it from time to time, but only in Qualified Investments; provided, however, if El Paso has delivered to Decommissioning Trustee a copy of an order of a state or federal regulatory agency that El Paso certifies is binding on El Paso and limits the investments in which all or a part of either Fund may be invested, the investment of such Fund shall not violate such order. A Fiduciary Investment Manager appointed by El Paso may direct investments and reinvestments of the Funds by written direction which shall certify that the directed investment qualifies as an investment in Qualified Investments and is within the limitation set forth in the preceding sentence. Decommissioning Trustee may rely upon such direction and certification without further inquiry or verification unless Decommissioning Trustee has actual knowledge that the directed investment does not satisfy the conditions and limitations of this Section 7.

In performing its duties and exercising its powers as Decommissioning Trustee hereunder, and in performing any investment management functions hereunder, Decommissioning Trustee shall comply with the following:

(i) it shall add all income, including interest, earned on the corpus of each Fund to such corpus as a part thereof, and shall owe the same duties with regard to such income as it owes with regard to such corpus;

(ii) it shall have the continuing duty to review the assets of each Fund to determine the appropriateness of the investments consistent with all terms, provisions and limitations of this Agreement, including without limitation to ensure compliance with the provisions of the investment guidelines of this Section 7, any order of a state or regulatory agency limiting investments that El Paso has delivered and certified to Decommissioning Trustee as provided above, and any other applicable governing regulations;

(iii) it shall not lend all or any part of either Fund to itself or to any of its officers or directors or permit any act of “self-dealing” prohibited by Applicable Tax Law;

(iv) it shall not invest or reinvest amounts in either Fund with, or in any instrument or security issued by, itself or any of its officers or directors, except that it may invest or reinvest amounts in the Funds in time deposits, demand deposits, or money market accounts of Decommissioning Trustee, and except that it may invest amounts in the Funds in mutual funds that contain securities issued by Decommissioning Trustee provided such securities constitute no more than five percent (5%) of the fair market value of the assets of such mutual funds at the time of the investment;

(v) it shall not invest or reinvest amounts in either Fund with, or in any instrument or security issued by, El Paso, its subsidiaries or affiliates or their successors or assigns, except that it may invest or reinvest amounts in the Funds in mutual funds that contain securities issued by El Paso provided such securities constitute no more than five percent (5%) of the fair market value of the assets of such mutual funds at the time of the investment; and

(vi) Notwithstanding anything to the contrary in this Agreement, if directed by El Paso, Decommissioning Trustee shall hold and maintain one or both of the Funds in a segregated account and invest and administer such Fund(s) separately from the assets of Decommissioning Trustee or other trusts.

(B) Fiduciary Investment Manager. Any amount of each Fund directed to be invested by a Fiduciary Investment Manager shall be invested and reinvested by Decommissioning Trustee as directed by such Fiduciary Investment Manager from time to time, but only in Qualified Investments; provided, however, if El Paso has delivered to a Fiduciary Investment Manager a copy of an order of a state or federal regulatory agency that El Paso certifies is binding on El Paso and limits the investments in which all or a part of a Fund may be invested, the investment of such Fund shall not violate such order. A Fiduciary Investment Manager appointed by El Paso may direct investments and reinvestments of the Funds by written direction which shall certify that the directed investment qualifies as an investment in Qualified Investments and is within the limitation set forth in the preceding sentence. Decommissioning Trustee may rely upon such written direction and certification without further inquiry or verification unless Decommissioning Trustee has actual knowledge that the directed investment does not satisfy the conditions and limitations of this Section 7.

In performing its duties and exercising its powers as a Fiduciary Investment Manager hereunder, a Fiduciary Investment Manager shall comply with the following:

(i) it shall direct the addition of all income, including interest, earned on the corpus of each Fund subject to its direction to such corpus as a part thereof, and shall owe the same duties with regard to such income as it owes with regard to such corpus;

(ii) it shall have a continuing duty to review the assets of each Fund subject to its direction to determine the appropriateness of the investments consistent with all terms, provisions and limitations of this Agreement, including without limitation to ensure compliance with the provisions of the investment guidelines of this Section 7, any order of a state or regulatory agency limiting investments that El Paso has delivered to such Fiduciary Investment Manager as hereinabove provided and any other applicable governing regulations;

(iii) it shall not direct the lending of all or any part of either Fund to itself or to any of its officers or directors or permit any act of “self-dealing” prohibited by Applicable Tax Law;

(iv) it shall not direct the investment or reinvestment of amounts in either Fund with, or in any instrument or security issued by, itself or any of its officers or directors;

(v) it shall not invest or reinvest amounts in either Fund with, or in any instrument or security issued by, Decommissioning Trustee or any of Decommissioning Trustee’s officers or directors, except that it may invest or reinvest amounts in the Funds in time deposits, demand deposits, or money market accounts of Decommissioning Trustee, and except that it may invest amounts in the Funds in mutual funds that contain securities issued by Decommissioning Trustee provided such securities constitute no more than five percent (5%) of the fair market value of the assets of such mutual funds at the time of the investment;

(vi) it shall not direct the investment or reinvestment of amounts in either Fund with, or in any instrument or security issued by El Paso, its subsidiaries or affiliates or associates or their successors or assigns of El Paso, except that it may direct the investment or reinvestment of amounts in the Funds in mutual funds that contain securities issued by El Paso provided such securities constitute no more than five percent (5%) of the fair market value of the assets of such mutual funds at the time of the investment; and

(vii) it shall provide Decommissioning Trustee directives concerning voting, consensual, and other rights and powers accruing in connection with assets of the Funds subject to such Fiduciary Investment Manager’s direction.

(C) General. It is the intent of El Paso that neither Decommissioning Trustee nor a Fiduciary Investment Manager shall have any powers that are greater than those provided to trustees under the Texas Trust Code or that are inconsistent with the limitations that are set out in this Section 7.

(D) Investments Standards. To the extent not inconsistent with the other provisions of this Section 7 and to the extent that Decommissioning Trustee does not currently require the assets of the Funds for the purpose of satisfying the liability of El Paso for Decommissioning and to pay Expenses:

(i) Decommissioning Trustee shall, in connection with investing and reinvesting assets of the Funds, exercise the same standard of care that a reasonable person would exercise in the same circumstances; provided, however, that this subsection 7.(D)(i) shall apply only as to those assets of the Funds that are not subject to the direction of a Fiduciary Investment Manager; and

(ii) a Fiduciary Investment Manager appointed to direct the investment and reinvestment of all or any portion of the assets of the Funds shall, with respect to such assets subject to its direction, exercise the same degree of care that a reasonable person would exercise in the same circumstances.

For purposes of this subsection entitled “Investment Standards”, a “reasonable person” means a prudent investor as described in Restatement of the Law, (Third), Trusts, Section 227, including the general comments and reporter’s notes with respect thereto.

(E) Qualified Investments. Qualified Investments include those investments meeting the investment standards, limitations, conditions, and requirements prescribed in the foregoing

Notwithstanding any other provision of this Section 7, nothing in this Section 7 shall be construed to permit any investment otherwise prohibited by any other provision of this Agreement, Applicable Law, or Applicable Tax Law. This Agreement and the investments of the Funds shall be interpreted and construed in a manner consistent with the parties’ intention that this Agreement and the Funds at all times comply with all requirements of the Nuclear Regulatory Commission and other applicable governmental regulations and rules, including without limitation the rules of the PUCT, the NMPRC, and the Federal Energy Regulatory Commission, including but not limited to the “Final Rule” regarding the formation, organization and purposes of nuclear plant decommissioning trust funds and for fund investments issued June 16, 1995, as may be amended from time to time.

SECTION 8. Expenses; Indemnification. El Paso shall pay all Expenses and, subject to Section 9.(D), may direct Decommissioning Trustee, in writing, to pay specified Expenses of a Fund from such Fund. El Paso shall certify in writing to Decommissioning Trustee whether and the extent to which an item is an Expense of a specified Fund and whether Applicable Tax Law permits its payment out of the assets of the Fund; and Decommissioning Trustee may, unless it has actual knowledge to the contrary, rely upon such certification without further inquiry or verification.

Except to the extent Decommissioning Trustee has actual knowledge to the contrary, Decommissioning Trustee shall be fully protected in relying upon the existence of any fact or state of facts represented to it in writing by El Paso or a duly appointed Fiduciary Investment Manager.

Except with respect to liability or fiduciary responsibility for any error or loss that may result by reason of the exercise or non-exercise of the duties, obligations, and/or fiduciary responsibility which are allocated to Decommissioning Trustee herein which is determined to be the result of Decommissioning Trustee’s own negligence or willful misconduct, El Paso shall indemnify Decommissioning Trustee, directly from El Paso’s own assets (including the proceeds of any insurance policy the premiums of which are paid from El Paso’s own assets), from and against any and all claims, demands, losses, damages, expenses (including, by way of illustration and not limitation, reasonable attorneys’ fees and other legal and litigation costs), judgments, and liabilities arising from, out of, or in connection with the administration or investment of the Funds. Decommissioning Trustee shall not be liable for any action taken by Decommissioning Trustee or any failure to act by Decommissioning Trustee if the action taken or the failure to act was directed by El Paso or a Fiduciary Investment Manager, if Decommissioning Trustee reasonably relied on such direction. This Section 8 shall survive the termination of this Agreement.

(A) Subject to the other provisions of this Section 9, Decommissioning Trustee shall make payments out of the Funds upon presentation by El Paso of (A) a certificate signed by El Paso (i) instructing Decommissioning Trustee to disburse amounts in the Funds in a manner designated in such certificate for purposes of paying for Decommissioning and (ii) certifying that disbursements, if any, directed to be made from assets of the Decommissioning Trust Fund are for payment of only those costs, liabilities, and expenses of Decommissioning that qualify as “nuclear decommissioning costs” under Applicable Tax law, and (B) documentation reasonably

(E) Unless Decommissioning Trustee has actual knowledge to the contrary, Decommissioning Trustee shall be fully protected in relying upon any certificate described in Section 9 without further inquiry or verification.

SECTION 10. Further Assurances. El Paso agrees that it will, at its sole expense, do all such further acts and things and execute and deliver all such additional conveyances, assignments, agreements, and instruments, as may be necessary or desirable or as

Decommissioning Trustee may at any time reasonably request in connection with the administration and enforcement of this Agreement, or relative to the Funds or any part thereof, or in order to assure and confirm unto Decommissioning Trustee its rights, powers, and remedies hereunder.

El Paso may provide general investment policies in writing to Decommissioning Trustee or a Fiduciary Investment Manager, but may not engage in the day-to-day management of the Funds or mandate, or itself make, individual investment decisions except to the extent that El Paso retains the right under this Agreement to approve investments in time deposits, demand deposits, or money market accounts of Decommissioning Trustee, in mutual funds that contain securities issued by Decommissioning Trustee (subject to the limitations elsewhere herein set forth), or in mutual funds that contain securities issued by El Paso, its subsidiaries or affiliates or their successors or assigns (subject to the limitations elsewhere herein set forth).

El Paso will regularly supply to Decommissioning Trustee and to each Fiduciary Investment Manager, and regularly update, essential information about Unit 3, including its description, useful life, the Decommissioning plan that El Paso intends to follow, El Paso’s anticipated liquidity needs once Decommissioning begins, and any other information that Decommissioning Trustee and a Fiduciary Investment Manager need to construct and maintain, over time, a sound investment plan for the Funds. El Paso will monitor the performance of the Decommissioning Trustee and each Fiduciary Investment Manager and, if necessary, replace them if they are not properly performing assigned responsibilities

SECTION 11. Irrevocability and Modification. This Agreement is irrevocable and may not be amended or modified except by a writing signed by the parties hereto and approved, to the extent required by Applicable Law, by applicable regulatory authority(s). The parties agree that they will execute any amendments requested by El Paso that are necessary to secure and maintain the qualification of the Decommissioning Trust Fund as a “Nuclear Decommissioning Reserve Fund” under Applicable Tax Law and the deduction of contributions to such Fund as provided by such law, or to comply with Applicable Law.

Not in limitation of the foregoing, if and to the extent that, now or in the future, federal tax law may extend certain tax benefits to a trust fund or funds that are created and maintained by El Paso for creation of a reserve or funds for costs associated with Decommissioning (hereinafter in this Section 11 referred to as such “other trusts”) which such other trusts would qualify as a “Nuclear Decommissioning Reserve Fund” under Applicable Tax Law, including without limitation, Internal Revenue Code section 468A, only if established and maintained pursuant to a single trust agreement for a particular nuclear power plant, the parties hereto, upon the creation of such other trusts may amend this Agreement by attaching hereto as an allonge the governing instruments by which such other trusts may be created. In such event, such other trusts shall be administered under the terms of this Agreement to the extent not inconsistent with the governing instruments by which such other trusts may be created and such other trusts shall thereafter be administered as separate funds under the terms of this Agreement.

SECTION 12. Obligation for Decommissioning. Nothing in this Agreement and no act or omission relating to the Funds shall be read, construed, understood, or interpreted to place any obligation whatsoever on Decommissioning Trustee or a Fiduciary Investment Manager

relating to Decommissioning or any Decommissioning Cost, all of which shall at all times remain the sole obligation of El Paso.

SECTION 13. Governing Law. This Agreement shall be deemed to be a contract made in Texas for all purposes and shall be construed in accordance with and governed by the laws of such State, including the provisions of the Texas Trust Code, with respect to all matters of construction, validity, and performance.

SECTION 14. Resignation and Replacement of Decommissioning Trustee or Fiduciary Investment Manager.

(A) Decommissioning Trustee may resign at any time without cause by giving at least 30 days prior written notice to El Paso, and El Paso may remove Decommissioning Trustee at any time with or without cause by giving written notice to Decommissioning Trustee, such resignation or removal to be effective on the acceptance of appointment by a successor Decommissioning Trustee under this Section 14. In case of the resignation or removal of Decommissioning Trustee, El Paso may appoint a successor Decommissioning Trustee by an instrument signed by El Paso. If a successor Decommissioning Trustee shall not have been appointed by El Paso within 30 days after the giving of such written notice of resignation or removal, Decommissioning Trustee or El Paso may apply to any court of competent jurisdiction to appoint a successor Decommissioning Trustee to act until such time, if any, as a successor Decommissioning Trustee shall have been appointed by El Paso and shall have accepted its appointment under this Section 14. Any successor Decommissioning Trustee so appointed by such court shall immediately and without further act be superseded by any successor Decommissioning Trustee appointed by El Paso as provided above.

(i) In appointing a Decommissioning Trustee, El Paso shall have the following duties which will be of a continuing nature:

(ii) Any successor Decommissioning Trustee, however appointed, shall execute and deliver to the predecessor Decommissioning Trustee an instrument accepting such appointment, and thereupon such successor Decommissioning Trustee, without

further act, shall become vested with all the estates, properties, rights, powers, duties, and trusts of the predecessor Decommissioning Trustee with like effect as if originally named as Decommissioning Trustee herein; and such predecessor Decommissioning Trustee shall duly assign, transfer, deliver, and pay over to such successor Decommissioning Trustee all moneys or other property then held by such predecessor Decommissioning Trustee upon the trusts expressed in this Agreement, shall do all acts necessary to vest title of record in such successor Decommissioning Trustee, and shall transfer and deliver to such successor Decommissioning Trustee copies of all records pertaining to the Funds and this Agreement. In addition, upon the written request of such successor Decommissioning Trustee, such predecessor Decommissioning Trustee shall execute and deliver to such successor Decommissioning Trustee an instrument transferring to such successor Decommissioning Trustee, upon the trusts expressed in this Agreement, all the estates, properties, rights, power, duties, and trusts of such predecessor Decommissioning Trustee.

(iii) Any successor Decommissioning Trustee, however appointed, shall be a bank or trust company with trust powers incorporated and doing business in the United States of America and having net worth of at least $150,000,000, if there be such an institution willing, able and legally qualified to perform the duties of Decommissioning Trustee hereunder upon reasonable or customary terms; provided however, that in calculating the $150,000,000 net worth requirement, the net worth of the Decommissioning Trustee’s parent corporation and/or affiliates may be taken into account only if such entities guarantee Decommissioning Trustee’s responsibilities to the Funds.

(iv) Any corporation into which Decommissioning Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which Decommissioning Trustee shall be a party, or any corporation to which substantially all the corporate trust business of Decommissioning Trustee may be transferred, shall, subject to the terms of subsection 14(A)(iii), be Decommissioning Trustee under this Agreement without further act.

(v) No successor Decommissioning Trustee (other than a successor by reason of an event described in Section l4(A)(iv)) shall be liable for any act, omission or breach of trust by a predecessor Decommissioning Trustee, whether or not such successor Decommissioning Trustee knows or should have known of such act, omission, or breach of trust, and shall have no duty to compel redress of any breach of trust by a predecessor Decommissioning Trustee.

(B) If a Fiduciary Investment Manager is appointed by El Paso hereunder, such appointment shall be made in writing; however, El Paso may not serve as a Fiduciary Investment Manager. A Fiduciary Investment Manager may resign at any time without cause by giving at least thirty (30) days prior written notice to El Paso, and El Paso may remove a Fiduciary Investment Manager at any time with or without cause by giving written notice to such Fiduciary Investment Manager. The resignation or removal of a Fiduciary Investment Manager is not conditioned on the acceptance of appointment by a successor Fiduciary Investment Manager under this Section 14; provided, however, that if a Fiduciary Investment Manager other than the Decommissioning Trustee resigns or is removed and is not replaced by El Paso,

Decommissioning Trustee shall, at that time, assume all investment responsibilities of such Fiduciary Investment Manager.

(i) In appointing a Fiduciary Investment Manager, El Paso shall have the following duties which will be of a continuing nature:

SECTION 15. Successors and Assigns; Additional Parties. This Agreement shall be binding upon and inure to the benefit of each party and its successors and permitted assigns.

SECTION 16. Termination of Funds. If not otherwise terminated sooner in accordance with the terms of this Agreement, each Fund shall end on the earlier of (A) the date specified in a written agreement between El Paso and Decommissioning Trustee and (B) the date that is twenty-one (21) years less one day after the death of the last survivor of the descendants of Joseph P. Kennedy, the father of President John F. Kennedy, that were living on April 1, 1986. Upon such termination, all of the assets of the Funds shall be distributed to El Paso. Notwithstanding the foregoing provisions of this Section 16, if one or both of the Funds shall be or become valid under Applicable Law for a period subsequent to the date set out in Section 16(B) (or, without limiting the generality of the foregoing, if legislation shall become effective providing for the validity or permitting the creation of such a fund for a period in gross exceeding the period for which such Fund is hereinabove stated to extend and be valid), then such Fund shall not terminate as aforesaid but shall extend to and continue in effect until (but only if such nontermination and extension shall then be valid under Applicable Law) such time as such Fund shall, under Applicable Law, cease to be valid.

SECTION 17. Accountings; Tax Returns and Reports; Audits.
