PURCHASE AND SALE AGREEMENT PURCHASE AND SALE AGREEMENT, dated as of April 18, 2006 (this “Agreement”), by and among ANP ERCOT ACQUISITION, LLC, a Delaware limited liability company (“Buyer”), TOPAZ POWER GROUP GP, LLC (“Topaz GP”), a Delaware limited liability company, and TOPAZ POWER GROUP LP, LLC (“Topaz LP”), a Delaware limited liability company (each of Topaz GP and Topaz LP a “Seller,” and together the “Sellers”). Buyer and Sellers are hereinafter collectively referred to as the “Parties” and each individually as a “Party.” WHEREAS, as of the date of this Agreement, Sellers own in the aggregate 100% of the issued and outstanding partnership units (the “Units”) of Coleto Creek Power, LP, a Texas limited partnership (the “Company”), which partnership units constitute all of the issued and outstanding equity interests in the Company; WHEREAS, the Company owns that certain coal fired power plant located in Goliad County, Texas, commonly known as the Coleto Creek Generating Facility (the “Plant”); WHEREAS, Buyer desires to purchase from Sellers 100% of the Units (the “Acquisition”); and WHEREAS, the Board of Directors of Buyer have approved and deem it advisable and in the best interest of Buyer to consummate the transactions contained in this Agreement; NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements contained in this Agreement, and intending to be legally bound, the Parties agree as follows: ARTICLE I PURCHASE AND SALE OF THE UNITS Section 1.1 Time and Place of Closing. Unless this Agreement shall have been terminated and the transactions herein contemplated shall have been abandoned pursuant to Section 7.1, and subject to the satisfaction or waiver of the conditions set forth in Article VI, the closing of the Acquisition (the “Closing”) will take place at the offices of Xxxxxx Xxxxxxxx Xxxxx & Xxxxxxxx LLP, One Liberty Plaza, New York, New York at 9:00 a.m. (local time) on the fifth business day following the date on which all of the conditions set forth in Article VI (other than those that by their nature are intended to be satisfied at the Closing) have been satisfied or waived, or at such other date, place or time as Sellers and Buyer may agree (the “Closing Date”). The transactions contemplated by this Agreement shall be deemed to be effective at 12:01 a.m. (local time) on the Closing Date. Section 1.2 Purchase and Sale of Units. (a) At the Closing, upon the terms and subject to the conditions of this Agreement, each Seller hereby agrees to sell to Buyer, and Buyer hereby agrees to purchase from such Seller, all Units owned by such Seller as of the Closing Date, in each case free and clear of any and all

Liens (other than Liens in favor of Buyer), for aggregate consideration from Buyer in respect of the Units equal to the sum of the following (together, the “Consideration”): (i) cash in an amount equal to the Cash Consideration plus (ii) the Escrow Amount. (b) At the Closing, Buyer shall pay the Consideration as follows: (i) cash in an amount equal to $10,000,000 (the “Escrow Amount”), which amount shall be paid by wire transfer of immediately available funds to the account (the “Escrow Account”) designated by an escrow agent selected by Sellers and reasonably acceptable to Buyer (the “Escrow Agent”) pursuant to an escrow agreement substantially in the form of Exhibit A hereto, with such modifications, if any, as shall be requested by the Escrow Agent and mutually acceptable to Sellers and Buyer (the “Escrow Agreement”) and which Escrow Amount shall be released to Sellers and/or Buyer, as the case may be, pursuant to Section 1.3; and (ii) each Seller shall receive from Buyer its Sharing Percentage of the Cash Consideration by wire transfer of immediately available U.S. funds. The “Sharing Percentage” of each Seller shall be equal to the “Sharing Percentage” set forth opposite such Seller’s name on Annex A hereto. All deliveries and payments to be made by Buyer to Sellers under this Agreement shall be made in accordance with the Sharing Percentages set forth on Annex A attached hereto, as amended, and Buyer shall not be liable for the allocation of particular deliveries and payments among Sellers so long as such deliveries and payments are made in accordance with Annex A. (c) For the purposes of this Agreement, the following terms shall be defined as follows: (i) The “Cash Consideration” shall mean cash in an amount equal to (i) $1,132,500,000 plus (ii) the Estimated Modified Net Working Capital minus Target Modified Net Working Capital (which amount, for the avoidance of doubt, may be a negative number) plus (iii) the positive amount of the Estimated Closing Date Capital Expenditure Account Balance. (ii) “Modified Net Working Capital,” as of a particular date, shall mean the current assets of the Company specified in Section 1.2 of the Disclosure Letter as of such date less the current liabilities of the Company specified in Section 1.2 of the Disclosure Letter as of such date, all as determined pursuant to, and using, the same accounting principles, methodologies and policies specified in Section 1.2 of the Disclosure Letter for determining Target Modified Net Working Capital and, to the extent not specified therein, in accordance with GAAP as applied in the preparation of the Financial Statements; provided, that, in furtherance and not in limitation of Section 1.2 of the Disclosure Letter in determining Modified Net Working Capital, current maturities of long-term Indebtedness and related interest and amounts payable under interest rate swaps shall be excluded.

(iii) “Target Modified Net Working Capital” shall have the meaning given such term in Section 1.2 of the Disclosure Letter. (iv) “Capital Expenditure Account Balance,” as of a particular date, shall mean the amount available in the capital expenditures reserve account, Account No. 00000000, with Citibank, N.A. (the “Capital Expenditure Account”), as of such date; provided that, at Closing, (A) the amount in the Capital Expenditure Account shall not exceed $40,000,000 and (B) all funds in the Capital Expenditure Account shall be transferred to Buyer. Section 1.3 Purchase Price Adjustment. (a) Sellers shall, at least five (5) business days prior to the Closing Date, cause to be prepared and delivered to Buyer a statement (the “Preliminary Statement”), setting forth Sellers’ good faith estimate of each of the Modified Net Working Capital as of the Closing Date (the “Closing Date Modified Net Working Capital”) and the Capital Expenditure Account Balance as of the Closing Date (the “Closing Date Capital Expenditure Account Balance”). The estimate of Closing Date Modified Net Working Capital is referred to herein as the “Estimated Modified Net Working Capital” and the estimate of the Closing Date Capital Expenditure Account Balance is referred to herein as the “Estimated Closing Date Capital Expenditure Account Balance.” (b) Within forty-five (45) calendar days after the Closing Date, Buyer shall cause to be prepared and delivered to Sellers a statement (the “Statement”) setting forth Buyer’s calculations of Closing Date Modified Net Working Capital, the Closing Date Capital Expenditure Account Balance and the components and calculation of each, which comments and calculations shall be included and made in accordance with Section 1.2 of the Disclosure Letter and, to the extent not provided for therein, GAAP (in each case as and to the same extent determined pursuant to Section 1.2(c)(ii)). At the same time, Buyer shall also cause to be prepared and delivered to Sellers a statement (the “Adjustment Statement”) setting forth the calculation (whether a positive or negative number) of (i) the amount of the Closing Date Modified Net Working Capital as shown on the Statement minus the Estimated Modified Net Working Capital plus (ii) the Closing Date Capital Expenditure Account Balance minus the Estimated Closing Date Capital Expenditure Account Balance (the sum of such amounts, whether a positive or negative number, the “Adjustment Amount”). Buyer shall provide Sellers and their accountants with access to the relevant books and records of the Company and the Sellers Employees to the extent required in connection with their review of and any dispute with respect to the Statement and the Adjustment Statement and shall furnish Sellers with any other information that might be relevant to the calculation of Closing Date Modified Net Working Capital or the Closing Date Capital Expenditure Account Balance. If, at any time prior to the final resolution of all disputed items on the Statement or the Adjustment Statement, additional information shall become known to Buyer or Sellers that would change the amount of the Closing Date Modified Net Working Capital or the Closing Date Capital Expenditure Account Balance shown on the Statement or the calculation thereof, then Buyer shall amend the Statement and Adjustment Statement to reflect such additional information. Buyer or Sellers shall promptly notify Sellers or Buyer, as applicable, upon becoming aware of any additional information prior to the end of the Resolution Period.

(c) After receipt of the Statement and the Adjustment Statement, Sellers will have thirty (30) calendar days from receipt to review the Statement and the Adjustment Statement together with the workpapers used in their preparation. Unless Sellers deliver to Buyer written notice setting forth in reasonable detail the specific items disputed by Sellers and a written statement setting forth Sellers’ calculation of each line item shown on the Statement so disputed and the amount in dispute (the “Sellers’ Statement”) on or prior to the thirtieth (30th) day after receipt of the Statement and the Adjustment Statement, Sellers will be deemed to have accepted and agreed to the Statement and the Adjustment Statement and such agreement will be final, binding and conclusive. Any items on the Statement or Adjustment Statement as to which Sellers have not given notice of their objection and provided an alternative calculation on Sellers’ Statement will be deemed to have been agreed upon by the Parties, subject to the penultimate sentence of Section 1.3(b). If Sellers so notify Buyer of their objections to any of the Statement or the Adjustment Statement and provide Buyer with Sellers’ Statement in a timely manner, Buyer and Sellers will, within thirty (30) calendar days following such notice (the “Resolution Period”), attempt to resolve their differences. Any resolution by Buyer and Sellers during the Resolution Period as to any disputed amounts will be final, binding and conclusive. If the amount claimed by Buyer on the Adjustment Statement to be owed by Sellers is less than the Escrow Amount, then, promptly after delivery of the Adjustment Statement, any amount on deposit in the Escrow Account that is in excess of the amount claimed by Buyer to be owed by Sellers under this Section shall be distributed from the Escrow Account to Sellers in accordance with the Escrow Agreement, and Buyer agrees to reasonably cooperate with Sellers in any necessary joint instruction to the Escrow Agent. Money released from the Escrow Account to Sellers shall be distributed to Sellers in accordance with the Sharing Percentages set forth on Annex A. If Buyer and Sellers do not resolve all disputed items by the end of the Resolution Period, then all items remaining in dispute will be submitted within ten (10) days after the expiration of the Resolution Period to a national independent accounting firm mutually acceptable to Buyer and Sellers (the “Neutral Accounting Arbitrator”); it being understood that no member of the Neutral Accounting Arbitrator’s engagement team shall have an existing professional relationship with Buyer or any of its Affiliates. The Neutral Accounting Arbitrator shall act as an arbitrator to determine only those items in dispute. All fees and expenses relating to the work, if any, to be performed by the Neutral Accounting Arbitrator will be allocated between Buyer, on the one hand, and Sellers, on the other hand, in inverse proportion as they shall prevail on the amounts of such disputed items so submitted (as finally determined by the Neutral Accounting Arbitrator). The Neutral Accounting Arbitrator will deliver to Buyer and Sellers a written determination (such determination to include a work sheet setting forth all material calculations used in arriving at such determination and to be based solely on information provided to the Neutral Accounting Arbitrator by Sellers and Buyer) of the disputed items within thirty (30) days of receipt of the disputed items (or as soon as practicable thereafter), which determination will be final, binding and conclusive. The final, binding and conclusive Statement and Adjustment Statement, which either are agreed upon by Buyer and Sellers or are delivered by the Neutral Accounting Arbitrator in accordance with this Section 1.3, will be the “Conclusive Statement” and the “Conclusive Adjustment Statement,” respectively. In the event that either Buyer or Sellers fails to submit its statement regarding any items remaining in dispute within the time determined by the Neutral Accounting Arbitrator, then the Neutral Accounting Arbitrator shall

render a decision based solely on the evidence timely submitted to the Neutral Accounting Arbitrator by Buyer and/or Sellers. (d) If the Adjustment Amount as shown on the Conclusive Adjustment Statement (the “Conclusive Adjustment Amount”) is a negative number, then the Cash Consideration will be reduced by the amount of the Conclusive Adjustment Amount, but not in excess of the Escrow Amount, and Buyer shall be entitled to payment of such amount from the Escrow Account by wire transfer of immediately available funds to an account or accounts designated by the Party entitled to receive such funds (and Sellers agree to cooperate reasonably in facilitating such payment, including by executing and delivering an appropriate joint instruction to the Escrow Agent). If the Conclusive Adjustment Amount is a positive number, then the Cash Consideration will be increased by the amount of the Conclusive Adjustment Amount, but not in excess of the Escrow Amount, and Buyer shall pay to Sellers cash equal to such amount, to be paid to an account or accounts designated in writing by Sellers prior to the date when such payment is due. All payments to be made pursuant to this Section 1.3(d) will be made on the fifth business day following the date on which Buyer and Sellers agree to, or the Neutral Accounting Arbitrator delivers, the Conclusive Statement and the Conclusive Adjustment Statement and, in the case of payment to Buyer, instruct the Escrow Agent by joint written instruction accordingly. If the Conclusive Adjustment Amount is a positive number, or is a negative amount that is less than the amount remaining on deposit in the Escrow Account, then, promptly after determination of the Conclusive Adjustment Amount, any amount remaining on deposit in the Escrow Account that is in excess of the lesser of the Conclusive Adjustment Amount and the Escrow Amount shall be distributed from the Escrow Account to Sellers in accordance with the Escrow Agreement, and Buyer agrees to reasonably cooperate with Sellers in any necessary joint instruction to the Escrow Agent. Money released from the Escrow Account to Sellers shall be distributed to Sellers in accordance with the Sharing Percentages set forth on Annex A. (e) Buyer acknowledges and agrees that its sole and exclusive remedy for any amount due to it pursuant to this Section 1.3 shall be its right to payment from the Escrow Account in an amount not to exceed the Escrow Amount. Sellers acknowledge and agree that their sole and exclusive remedy for any amount due to them pursuant to this Section 1.3 shall be the right to payment from Buyer in an amount not to exceed the Escrow Amount. Section 1.4 Purchase Price Allocations. Sellers and Buyer agree that the Consideration shall be allocated for federal income tax purposes in accordance with Section 1060 of the Internal Revenue Code of 1986, as amended (the “Code”). Buyer shall, within sixty (60) days after the Conclusive Adjustment Amount is determined, prepare and deliver to Sellers for their review a schedule allocating the Consideration (and any other items that are required for federal income tax purposes to be treated as part of the purchase price of the Units) among the purchased assets (such schedule, the “Allocation”). Sellers shall review such Allocation and provide any objections to Buyer within thirty (30) days after the receipt thereof. In the event Sellers do not object to Purchaser’s Allocation, such Allocation shall be final (the “Final Allocation”) and Buyer and Sellers shall report such Final Allocation for Tax purposes and file Tax Returns (including Form 8594 under Section 1060 of the Code) in a manner consistent with such mutually agreed Final Allocation. If Sellers raise any objection to the Allocation, the Parties will negotiate in good faith to resolve such objection(s). If the Parties are unable to agree on the Allocation within sixty (60) days after Sellers raise such objections, then Sellers and

Buyer shall not be bound by the Allocation and each Party shall allocate the Purchase Price to the purchased assets as such Party determines is proper. Section 1.5 Preliminary Information. At least five (5) business days prior to the Closing Date, Sellers shall deliver to Buyer instructions designating the account or accounts to which the Cash Consideration shall be deposited by federal funds wire transfer of immediately available funds on the Closing Date. Section 1.6 Sellers’ Closing Deliverables.

Each of the Company Insurance Policies is valid, enforceable, existing and binding, and the premiums due thereon have been timely paid. There are no outstanding unpaid claims under any of the Company Insurance Policies with respect to the Company, except in the ordinary course of business consistent with past practice. Since September 30, 2005, the Company has not received notice of cancellation, termination or non-renewal of any Company Insurance Policy or been denied insurance coverage. The Company Insurance Policies are sufficient for compliance with applicable Law and all Contracts to which the Company is a party or by which it or any of its assets are bound, and are in such amounts, against such risks and losses, and on such terms and conditions as are consistent with industry practice in the business of the Company. Buyer acknowledges and agrees that, with respect to the Company, none of the Company Insurance Policies will remain in effect after the Closing Date. Section 3.17 Regulatory Matters. The Company is subject to regulation (i) under Texas utility Law as a “power generation company” (as such term is defined under PURA), and (ii) under the ERCOT protocols as a “resource entity” (as such term is defined in the ERCOT protocols). Except as set forth in the immediately preceding sentence, the Company is not and has not been subject to regulation as a public utility, public utility holding company or public service company (or similar designation) by any Governmental Authority. The Company is not and has not been engaged in the sale of electricity in interstate commerce. The Company is an “exempt wholesale generator” within the meaning of the Public Utility Holding Company Act of 2005.

(b) Except as set forth in Section 3.18(b) of the Disclosure Letter, each Company Affiliate Contract listed in Section 3.18(a) of the Disclosure Letter was entered into in the ordinary course of business and on terms no less favorable than would have been reached on an arms-length basis, except those of a type available to Sellers Employees generally.

Each Sellers Employee who accepts such offer of employment shall be hereinafter referred to as a “Transferred Employee.” Unless otherwise agreed between Buyer and a Transferred Employee, offers of employment shall be on an at-will basis. (b) For the one-year period commencing on the Closing Date (the “Benefits Maintenance Period”), the Buyer shall (i) provide each Transferred Employee with at least the same rate of base pay and same bonus opportunities to which each such Transferred Employee is entitled immediately prior to the Closing Date as set forth on Section 3.10(a) and Section 3.10(b) of the Disclosure Letter, as applicable, and (ii) provide the Transferred Employees with employee benefits (including, for the avoidance of doubt, retirement, retiree medical, welfare and fringe benefits) that are, in the aggregate, at least equal in value to the benefits provided to the Transferred Employees under the Sellers Benefit Plans immediately prior to the Closing Date. Any employee benefit plans, programs or policies of Buyer or its Affiliates or Subsidiaries in which Transferred Employees become eligible to participate after the Closing Date shall be referred to hereinafter as, the “Buyer Benefit Plans.” Neither Buyer nor any Buyer Benefit Plan shall receive assets from the Sellers Benefit Plans or any other benefit plan maintained by Sempra, Topaz Power Group, STS, Sellers or their respective Affiliates. In addition, Sempra, Topaz Power Group, STS, Sellers or their respective Affiliates, successors or assigns, as applicable, shall retain any liabilities or obligations relating to Sellers Employees under any Sellers Benefit Plan or any other benefit plan maintained by Sempra, Topaz Power Group, STS, Sellers or their respective Affiliates that have accrued prior to the Closing Date. (c) To the extent that service is relevant for any purpose, including eligibility to participate, vesting credit, eligibility to commence benefits, benefit accrual, early retirement subsidies, and severance benefits, under a Buyer Benefit Plan, Buyer shall credit, effective as of the Closing Date and under the applicable Buyer Benefit Plans, each Transferred Employee with such Transferred Employee’s service with, or recognized by, Sempra, Topaz Power Group, STS, Sellers, the Company or their respective Affiliates (including their predecessors) prior to or on the Closing Date, to the same extent as if such service were with Buyer; provided, however, that

such service shall not be required to be recognized to the extent that such recognition would result in a duplication of benefits. (d) Buyer shall provide at least the same amount and type of severance benefit as that described in Section 5.6(d) of the Disclosure Letter to any Transferred Employee who, during the Benefits Maintenance Period, (i) is terminated without cause or (ii) elects to terminate his or her employment with Buyer or its Subsidiaries within seven (7) days after Buyer notifies such Transferred Employee of Buyer’s intent to (1) reduce such Transferred Employee’s rate of base pay or bonus opportunity or (2) assign such Transferred Employee to a principal place of work that is greater than fifty (50) miles from such Transferred Employee’s principal place of work immediately prior to the Closing Date. In addition, Buyer agrees to indemnify Sempra, Topaz Power Group, STS, Sellers and their Affiliates for any severance pay, termination pay or similar pay to which a Sellers Employee may become entitled in the event (i) Buyer fails to make an offer of employment to such Sellers Employee (excluding, for purposes of this Section 5.6(d)(i) only, any STS Employee) or (ii) any offer of employment by Buyer to such Sellers Employee fails to comply with the terms and conditions of Section 5.6(a) of this Agreement. (e) With respect to any Buyer Benefit Plans, except to the extent otherwise required by applicable law, Buyer shall (i) waive, or cause the waiver of, all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Transferred Employees and their eligible dependents, and (ii) for purposes of satisfying any deductible or out-of-pocket requirements, provide each Transferred Employee and their eligible dependents with credit for any co-payments and deductibles paid prior to the date hereof under the analogous Sellers Benefit Plan. Sellers will furnish Buyer with such information concerning the amount of such co-pays and deductibles as may be reasonably necessary to enable Buyer to comply with the provisions of this Section 5.6(e) (f) In accordance with the elections made pursuant to Section 401(a)(31) of the Code by Transferred Employees and to the extent permissible under any applicable Law, Sellers shall facilitate the transfer of assets held in the respective accounts of such Transferred Employees from the Sempra Energy Retirement Savings Plan to a defined contribution benefit plan or plans designated by Buyer. Buyer agrees to cause such Buyer defined contribution plan or plans to accept intact rollovers of cash and loans associated with such Transferred Employee accounts and Buyer will cooperate with Sellers to enable such rollovers to occur before any such loans become defaulted. (g) Buyer agrees to provide any required notice under the WARN Act and to otherwise comply with the WARN Act or any similar law with respect to any “plant closing” or “mass layoff” (as defined in the WARN Act) affecting Sellers Employees and occurring on or after the Closing Date. (h) After the date of this Agreement and prior to the Closing Date, Buyer shall have the right to meet with Sellers Employees, as a group and not on an individual one-on-one basis, from time to time to discuss post-Closing employment matters; provided, however, that Buyer shall notify Sellers at least two (2) business days prior to the date on which a meeting is proposed to be held, and Sellers shall have the right to have one or more Representatives of Sellers or their Affiliates (except any Sellers Employees) attend such meeting. If any materials are to be

provided or used during a meeting, Buyer shall provide copies of such materials to Sellers at least two (2) business days prior to such meeting, and the use or provision of such materials during the meeting will be subject to Sellers’ reasonable consent. (i) After the date of this Agreement and prior to the Closing Date, Buyer shall have the right, with the consent of Sellers, to meet with those STS Employees who Buyer determines in good faith are reasonably necessary for its operation of the business of the Company, to discuss potential employment with Buyer from and after the Closing Date; provided, however, that Buyer shall notify Sellers of the STS Employees with which Buyer would like to meet at least five (5) business days prior to the date on which a meeting is proposed to be held and Sellers shall have the right to have one or more Representatives of Sellers or their Affiliates attend such meeting. If any materials are to be provided or used during a meeting, Buyer shall provide copies of such materials to Sellers at least two (2) business days prior to such meeting and the use or provision of such materials during the meeting will be subject to Sellers’ consent (not to be unreasonably withheld or delayed). Notwithstanding anything herein to the contrary, the parties acknowledge and agree that nothing in this Section 5.6(i) shall obligate the Buyer to make any offer of employment to any STS Employee or obligate Sellers to make any STS Employee available to Buyer for employment. In addition, in the event Buyer does make an offer of employment to an STS Employee, Buyer agrees to treat such STS Employee as a Seller Employee (and to the extent such STS Employee accepts such offer, a Transferred Employee) for purposes of the provisions of this Section 5.6 (including, without limitation, the offer of employment conditions set forth in Section 5.6(a), but excluding Section 5.6(h)). Furthermore, with respect to any STS Employee who is not offered employment by Buyer prior to the Closing Date, (i) Sellers and their Affiliates will retain liability for any severance pay, termination pay or similar pay to which any such STS Employee may become entitled and (ii) Buyer will not, and will not cause its Affiliates to, directly or indirectly, for the six (6) month period from the Closing Date, for Buyer’s or such Affiliate’s account or for the account of any Person, solicit or induce, or assist a third party in soliciting or inducing, any such STS Employee, to leave or cease their employment relationship with Sellers, STS or their respective affiliates, for any reason whatsoever, or hire or otherwise engage, or assist a third party in hiring or otherwise engaging, any such STS Employee. Section 5.7 Tax Matters. (a) Sellers shall prepare and file, or cause to be prepared and filed, any Tax Returns of the Company for any taxable period ending on or before the Closing. Buyer shall prepare and file, or cause to be prepared and filed, all Tax Returns of the Company for any taxable period ending after the Closing Date (for purposes of the Texas Franchise Tax the terms “taxable period” or “period” that appear in this Section 5.7 shall mean the “privilege period” as that term is used in administering the Texas Franchise Tax), including all Tax Returns that relate to periods beginning before and ending after the Closing Date (“Straddle Returns”). All Straddle Returns shall be prepared on a basis consistent with existing procedures and practices of the Company for filing such Tax Returns. Buyer shall not, or allow the Company to, amend a Tax Return (or extend the statute of limitations for assessment or collection of any Taxes with respect to a Tax Return) that relates to any period (portion thereof) ending on or before the Closing Date without the prior written permission of Seller (which will not be unreasonably withheld). Seller shall have the right to review Straddle Returns and shall be entitled to fully participate in that

portion of any proceedings or audits relating to Taxes with respect to which Sellers may incur Tax liability. Buyer agrees to cooperate with Sellers, and Sellers agree to cooperate with Buyer, to provide any information requested by Sellers or Buyer, as the case may be, in order to prepare such returns. (b) Sellers shall be liable for, and shall indemnify and hold Buyer harmless from, any taxes imposed on the Company with respect to any period ending on or before the Closing Date, which shall include Sellers’ pro-rata portions of any Straddle Period Taxes, as determined under Section 5.7(c) or taxes based upon real or personal property as determined under Section 5.7(d). Buyer’s shall be liable for, and shall indemnify and hold Sellers harmless from, any Taxes imposed on the Company with respect to any period beginning after the Closing Date, which shall include Buyer’s pro-rata portions of any Straddle Period Taxes, as determined under Section 5.7(c) or taxes based upon real or personal property as determined under Section 5.7(d). (c) In the case of any taxable period beginning before and ending after the Closing Date (the “Straddle Period”), the Party liable for the payment of and indemnification for Taxes related to such period and the amount of Tax allocated to such Party shall be determined on a per diem basis. (d) All real or personal property Taxes assessed on an annual basis shall be prorated between Sellers and Buyer as of the Closing Date based on the assumption that an equal amount of Taxes applies to each day of the year, regardless of how any installment payments are billed or made, except that Buyer will bear all supplemental or other state and local real and personal property Taxes which arise out of a change in ownership of the Companies. Sellers shall cause the Company to pay their portion of such real and personal property Taxes to the Buyer on or prior to the Closing, and except as provided in the next sentence, shall have no further liability or obligation with respect to such Taxes. If the amount of all real and personal property Taxes due for the 2006 year (commencing January 1, 2006) has not been assessed by the taxing authorities as of the Closing Date, then the amount of real and personal property Taxes as prorated between Sellers and Buyer for the 2006 tax will be estimated on the basis of the 2005 tax year’s real and personal taxes and such amount will be subject to a true-up adjustment after the Closing Date based upon the actual amount of Taxes assessed. (e) After the Closing Date in the case of any audit, examination, or other proceeding with respect to Taxes (“Tax Proceeding”) for which Sellers are or may be liable hereunder, Buyer shall inform Sellers within thirty (30) days of the receipt of any notice of such proceeding and shall keep Sellers informed of the progress of such proceedings. Seller shall be entitled to fully participate in any proceeding. Buyer shall not agree to any adjustments which affect taxable periods for which Sellers are liable for payment of Tax without first receiving the consent of Sellers, which consent shall not be unreasonably withheld. (f) All excise, sales, use, transfer (including real property transfer or gains), stamp, documentary, filing, recordation and other similar taxes, together with any interest, additions or penalties with respect thereto and any interest in respect of such additions or penalties, resulting directly from the Acquisition (the “Transfer Taxes”), shall be paid by Buyer.

Section 5.8 Escrow Agreement. On or prior to the Closing Date, Buyer and Sellers will execute and deliver, and will use reasonable best efforts to cause the Escrow Agent to execute and deliver, the Escrow Agreement. Section 5.9 Mutual Release. Effective as of the Closing, Sellers, on the one hand, and Buyer on the other hand, hereby unconditionally and irrevocably and forever releases and discharges the other, its respective Affiliates, successors and assigns, and any present or former directors, managers, officers, employees or agents of the other (collectively, the respective “Released Parties”), of and from, and hereby unconditionally and irrevocably waives, any and all claims, debts, losses, expenses, proceedings, covenants, liabilities, suits, judgments, damages, actions and causes of action, obligations, accounts, and liabilities of any kind or character whatsoever, known or unknown, suspected or unsuspected, in contract, direct or indirect, at law or in equity (collectively, the respective “Released Claims”) that such Party ever had, now has or ever may have or claim to have against any Released Party, for or by reason of any matter, circumstance, event, action, inaction, omission, cause or thing whatsoever arising prior to the Closing and to the extent based upon the applicable Sellers’ capacity as a holder of Units, including without limitation any Released Claims arising under Environmental Law, and regardless of whether the released claims are the result of the sole, gross, active passive concurrent or comparative negligence, strict liability or other fault or violation of any law of or by and Released Party; provided, however, that this release does not extend to Released Claims to enforce the terms or any breach of this Agreement or any of the provisions set forth herein. Following the Closing, Buyer shall cause the Company to release Sellers to the same extent Sellers have been released by Buyer in accordance with this Section 5.9. Section 5.10 SES PPA. Simultaneously with and effective as of the Closing, Buyer shall (or shall cause the Company to) deliver Security (as defined in the Master Power Purchase and Sale Agreement, dated as of June 28, 2004, by and between the Company and Sempra Energy Solutions (as amended pursuant to the SES PPA Amendment, the “SES PPA”)) in the amount of Party A’s Security Amount (as defined in the SES PPA) in accordance with the SES PPA. Section 5.11 Intercompany Arrangements. Sellers shall cause all Intercompany Arrangements, excluding any Surviving Intercompany Arrangements, to be terminated concurrently with the Closing. For purposes of this Agreement, (a) “Intercompany Arrangement” means any contract, agreement or arrangement in respect of any intercompany transaction between the Company, on the one hand, and either Seller or any of its Affiliates, on the other hand, whether or not such transaction relates to any contribution to capital, loan, the provision of goods or services, tax sharing arrangements, payment arrangements, intercompany advances, charges or balances or the like and (b) “Surviving Intercompany Arrangement” means any Intercompany Arrangements listed in Exhibit D-2. For the avoidance of doubt, no such termination of an Intercompany Agreement pursuant to this Section 5.11 (including with respect to termination of the Amended and Restated Asset Management Agreement (Topaz) dated as of July 1, 2004, by and between Coleto Creek Power, LP and Sempra Texas Services, LP.) shall in any way modify, release or otherwise extinguish any rights or obligations explicitly surviving the termination of such Intercompany Agreement pursuant to the terms thereof.

Section 5.12 Casualty. Sellers will (a) on or prior to Closing, promptly file or cause to be filed, in the ordinary course of business and in accordance with its customary practices and procedures, all insurance claims relating to any damage to or destruction of all or any portion of the Plant occurring prior to the Closing, and (b) pay or cause to be paid to the Company, all proceeds of insurance claims (other than claims for business interruption insurance and amounts paid or accrued in respect of Liabilities reflected on or contemplated by the financial statements of the Company) filed on or prior to the Closing, not otherwise payable to the Company and relating to damage or destruction of all or a portion of the plant occurring prior to the Closing. Section 5.13 Transition Services Agreement. Sellers agree to provide the services described in Section 5.13 of the Disclosure Letter, subject to terms and conditions to be mutually agreed by the Sellers and Buyer. The Parties shall use commercially reasonable efforts to enter into a Transition Services Agreement within thirty (30) Business Days of the date hereof, which Transition Services Agreement shall become effective on the Closing Date. “Transition Services Agreement” means that certain agreement, dated not later than the Closing Date, between Seller and Purchaser for the provision by Seller of the services described in Section 5.13 of the Disclosure Letter. ARTICLE VI CONDITIONS TO CONSUMMATION OF THE ACQUISITION Section 6.1 Conditions to Buyer’s and Sellers’ Obligations to Consummate the Acquisition. The respective obligations of Buyer and Sellers to consummate the Acquisition are subject to the satisfaction on or prior to the Closing Date of each of the following conditions: (a) No Law or Order shall exist or shall have been enacted, entered, promulgated or enforced by any Governmental Authority which prohibits or makes illegal consummation of the Acquisition or any of the other transactions related thereto.

be true and correct unless the failure or failures of all such representations and warranties to be so true and correct, without giving effect to any qualification as to materiality or Buyer Material Adverse Effect set forth in such representations or warranties, would reasonably be expected, in the aggregate, to have a Buyer Material Adverse Effect.

All Actions arising out of or relating to this Agreement shall be heard and determined in any state or federal court sitting in the City of New York, and the parties hereby irrevocably submit to the exclusive jurisdiction of such courts in any such Action and irrevocably waive the defense of an inconvenient forum to the maintenance of any such Action. Each Party irrevocably consents to the service of any and all process in any such Action by the mailing of copies of such process to such Party at its address specified in Section 8.5. The parties agree that a final judgment in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Nothing in this Section 8.6 shall affect the right of any Party to serve legal process in any other manner permitted by Law. The consents to jurisdiction set forth in this Section 8.6 shall not constitute general consents to service of process in the State of New York and shall have no effect for any purpose except as provided in this Section 8.6 and shall not be deemed to confer rights on any Person other than the parties. EACH PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY. Section 8.7 Descriptive Headings. The table of contents and descriptive headings used in this Agreement are inserted for convenience of reference only and shall in no way be construed to define, limit, describe, explain, modify, amplify, or add to the interpretation, construction or meaning of any provision of, or scope or intent of, this Agreement nor in any way affect this Agreement. Section 8.8 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but any of which together shall constitute one and the same instrument. Section 8.9 Fees and Expenses. Whether or not this Agreement and the transactions contemplated by this Agreement are consummated, and except as otherwise expressly set forth in this Agreement, all costs and expenses (including legal and financial advisory fees and expenses) incurred in connection with, or in anticipation of, this Agreement and the transactions contemplated by this Agreement shall be paid by the Party incurring such expenses. Each of Sellers, on the one hand, and Buyer, on the other hand, shall indemnify and hold harmless the other Party from and against any and all claims or liabilities for financial advisory and finders’ fees incurred by reason of any action taken by such Party or otherwise arising out of the transactions contemplated by this Agreement by any Person claiming to have been engaged by such Party.

Section 8.10 Interpretation. (a) The phrase “to the knowledge of” any Person or any similar phrase shall mean such facts and other information which as of the date of determination are actually known to any executive officer of such Person, after due inquiry; it being understood that those Persons listed in Section 8.10 of the Disclosure Letter shall be deemed to have knowledge. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement. When a reference is made in this Agreement to Sections, Exhibits, the Disclosure Letter or an Annex, such reference shall be to Sections, Exhibits, the Disclosure Letter or an Annex of this Agreement, respectively, unless otherwise indicated. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”. The words “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “or” is not exclusive. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. References to a Person are also to its permitted successors and assigns. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. (b) For purposes of this Agreement, the term: (i) “Affiliate” means, unless otherwise indicated, any Person that directly, or indirectly through one or more intermediaries, controls, is controlled by or is under common control with the Person specified; (ii) “Company IP” means all material Intellectual Property owned, held or used by the Company, including all material patent, copyright, trademark and service xxxx registrations and applications and domain names issued to, assigned to and filed by the Company; (iii) “Intellectual Property” means all U.S. intellectual property, including: (a) patents, inventions, discoveries, processes, designs, techniques, developments, technology, and related improvements and know-how, whether or not patented or patentable; (b) copyrights and works of authorship in any media, including computer hardware, software, firmware, applications, files, systems, networks, databases and compilations, documentation and related textual works, graphics, advertising, marketing and promotional materials, photographs, artwork, drawings, articles, textual works, and Internet site content; (c) trademarks, service marks, trade names, brand names, corporate names, domain names, logos trade dress and other source indicators and the goodwill of any business symbolized thereby; and (d) trade secrets, drawings, blueprints and all non-public, confidential or proprietary information, documents, materials, analyses, reach and lists; (iv) “Person” means any individual, corporation, partnership, limited liability company, firm, joint venture, association, joint-stock company, trust, unincorporated organization, representative office, branch, Governmental Authority or other similar entity such determination; and (v) “Subsidiary” means, with respect to any Person, any other Person of which such Person (either alone or through or together with any other Subsidiary) owns, directly or indirectly, 50% or more of the outstanding equity securities or securities carrying 50% or more of the voting power in the election of the board of directors or other governing body of such Person. (c) The inclusion of any matter in any Section of the Disclosure Letter in connection with any representation, warranty, covenant or agreement that is qualified as to materiality is not an admission by the Party making such disclosure that such matter is material or would (or

would be reasonably expected to) impair the ability of such Party to consummate the transactions contemplated by this Agreement. Matters disclosed in one Section or subsection of the Disclosure Letter are deemed to be disclosed with respect to each Section or subsection of the Disclosure Letter. Section 8.11 Third-Party Beneficiaries. Except for the provisions of Section 5.9, this Agreement is solely for the benefit of Sellers and their respective successors and permitted assigns, with respect to the obligations of Buyer under this Agreement, and for the benefit of Buyer, and its successors and permitted assigns, with respect to the obligations of Sellers, under this Agreement. Notwithstanding anything contained in this Agreement to the contrary, nothing in this Agreement, expressed or implied, is intended to confer on any Person other than the parties or their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement. Section 8.12 No Waivers. Except as otherwise expressly provided in this Agreement, no failure to exercise, delay in exercising, or single or partial exercise of any right, power or remedy by any Party, and no course of dealing between the parties, shall constitute a waiver of any such right, power or remedy. No waiver by a Party of any default, misrepresentation, or breach of warranty or covenant under this Agreement, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant under this Agreement or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. No waiver shall be valid unless in writing and signed by the Party against whom such waiver is sought to be enforced. Section 8.13 Specific Performance. The parties to this Agreement agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the parties shall be entitled to specific performance of the terms of this Agreement and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or in equity.

IN WITNESS WHEREOF, each of the undersigned has caused this Agreement to be duly signed as of the date first above written.

All capitalized terms used and not otherwise defined in this Disclosure Letter shall have the meanings ascribed to such terms in the Agreement. To the extent that any representation or warranty contained in the Agreement is limited or qualified by the materiality of the matters that are the subject of such representation or warranty, the inclusion of any matter in this Disclosure Letter shall not constitute a determination by Sellers that such matter is material. Nor in such cases where a representation or warranty is given or other information is provided shall the disclosure of any matter in this Disclosure Letter imply that any other, undisclosed matter having a greater value or other significance is material. The inclusion in this Disclosure Letter of any matter or document shall not imply any representation, warranty or undertaking not expressly given in the Agreement, nor shall such disclosure be taken as extending the scope of any such representation or warranty.
