1.2 Other Definitional and Interpretive Matters. Unless otherwise expressly provided, for purposes of this Agreement, the following rules of interpretation apply:

(a) Calculation of Time Period. When calculating the period of time before which, within which, or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period will be excluded. If the last day of such period is a non-Business Day, the period in question will end on the next succeeding Business Day.

(b) Dollars. Any reference in this Agreement to “dollars” or “$” means U.S. dollars.

(c) “Exclusively in the Business”. With reference to assets owned by Seller, and liabilities of Seller, which are used by, in, or for, or relate to, the Business, the phrases “exclusively in the Business,” “exclusively to the Business,” and other statements of similar import will be construed to refer to assets or liabilities that are devoted exclusively to (or in the case of liabilities, are related exclusively to) the Business.

(d) Exhibits and Schedules. Unless otherwise expressly indicated, any reference in this Agreement to an “Exhibit” or a “Schedule” refers to an Exhibit or Schedule to this Agreement. The Exhibits and Schedules to this Agreement are hereby incorporated and made a part hereof as if set forth in full herein and are an integral part of this Agreement. Any capitalized terms used in any Schedule or Exhibit but not otherwise defined therein are defined as set forth in this Agreement.

(e) Gender and Number. Any reference in this Agreement to gender includes all genders, and the meaning of defined terms applies to both the singular and the plural of those terms.

(f) Headings. The provision of a Table of Contents, the division of this Agreement into Articles, Sections, and other subdivisions, and the insertion of headings are for convenience of reference only and do not affect, and will not be utilized in construing or interpreting, this Agreement. All references in this Agreement to any “Section” are to the corresponding Section of this Agreement unless otherwise specified.

(g) “Herein”. The words such as “herein,” “hereinafter,” “hereof,” and “hereunder” refer to this Agreement (including the Schedules and Exhibits to this Agreement) as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires.

(h) “Including”. The word “including” or any variation thereof means “including, without limitation” and does not limit any general statement that it follows to the specific or similar items or matters immediately following it.

(i) “To the extent”. The words “to the extent” when used in reference to a liability or other matter, means that the liability or other matter referred to is included in part or excluded in part, with the portion included or excluded determined based on the portion of such liability or other matter exclusively related to the subject. For example, if 40 percent of a liability is attributable to the Business, then a statement that Buyer will assume the liability “to the extent related to the operation of the Business” means that Buyer will assume 40 percent of the liability. As an additional example, if a performance obligation attributable to the Business is by its terms to be performed prior to and following the Effective Time, a statement that Buyer will assume the obligation “to the extent such obligation relates to the period from and after the Effective Time” means that Buyer will assume all liability for the performance from and after the Effective Time, and that Seller will remain liable for any failure to perform such obligations prior to the Effective Time.

1.3 Joint Negotiation and Preparation of Agreement. The Parties and Parent have participated jointly in the negotiation and drafting of this Agreement and, in the event an ambiguity or question of intent or interpretation arises, this Agreement will be construed as jointly drafted by the Parties and Parent and no presumption or burden of proof favoring or disfavoring any Party or Parent will exist or arise by virtue of the authorship of any provision of this Agreement.

ARTICLE III

PURCHASE PRICE

3.1 Purchase Price. (a)The purchase price for the Purchased Assets (the “Purchase Price”) will be an amount equal to $620,000,000 (the “Base Price”), adjusted as follows: (i) the Base Price will be increased by the Adjustment Amount if the Adjustment Amount is a positive number; and (ii) the Base Price will be reduced by the Adjustment Amount if the Adjustment Amount is a negative number. The Adjustment Amount will be determined in accordance with the requirements set forth on Exhibit 3.1.

(b) Within five Business Days of the settlement of any transaction involving any matched Off-System Purchases and Sales with a settlement date after the Closing Date, Buyer will for each such transaction pay Seller the Off-System Net Payment Amount calculated in accordance with Exhibit 3.1. For purposes of this Section 3.1(b), (i) “matched Off-System Purchases and Sales” means a transaction in which the Business purchased physical gas and simultaneously agreed to sell forward an equivalent volume of gas to a non-jurisdictional customer as part of Seller’s business of Off-System Purchases and Sales, (ii) the settlement of any such transaction shall be the later of (A) the date of delivery by the Business of the physical gas pursuant to such forward sale and (B) the date of payment by the non-jurisdictional customer and (iii) only Off-System Purchases and Sales pursuant to Business Agreements shall be taken into account.

3.2 Determination of Purchase Price.

(a) No later than five days prior to the Closing Date, Seller will prepare in good faith and deliver to Buyer a reasonably detailed estimate of the Purchase Price, based on Seller’s good faith estimate of the Adjustment Amount (such estimated Purchase Price being referred to herein as the “Closing Payment Amount”).

(b) Within 120 days after the Closing Date, Seller will prepare and deliver to Buyer a statement (the “Post-Closing Adjustment Statement”) that reflects Seller’s determination of (i) the Adjustment Amount, and (ii) the Purchase Price based on the Adjustment Amount. In addition, Seller will provide Buyer with supporting calculations, in reasonable detail, for such determinations at the time it delivers the Post-Closing Adjustment Statement. Buyer agrees to cooperate with Seller in connection with Seller’s preparation of the Post-Closing Adjustment Statement and related information, and will provide Seller with access to its books, records, information, and employees as Seller may reasonably request.

(c) The amounts determined by Seller as set forth in the Post-Closing Adjustment Statement will be final, binding, and conclusive for all purposes unless, and only to the extent, that within 30 days after Seller has delivered the Post-Closing Adjustment Statement Buyer notifies Seller of any dispute with matters set forth in the Post-Closing Adjustment Statement. Any such notice of dispute delivered by Buyer (an “Adjustment Dispute Notice”) will identify with specificity each item in the Post-Closing Adjustment Statement with respect to which Buyer disagrees, the basis of such disagreement, and Buyer’s position with respect to such disputed item.

(d) If Buyer delivers an Adjustment Dispute Notice in compliance with Section 3.2(c), then (i) the undisputed portion of the total proposed Adjustment Amount set forth in the Post-Closing Adjustment Statement will be paid by the appropriate Party, in accordance with the payment procedures set forth in Section 3.2(e); and (ii) Buyer and Seller will attempt to reconcile their differences and any resolution by them as to any disputed amounts will be final, binding, and conclusive for all purposes on the Parties. If Buyer and Seller are unable to reach a resolution with respect to all disputed items within 45 days of delivery of the Adjustment Dispute Notice, Buyer and Seller will submit any items remaining in dispute for determination and resolution to the Independent Accounting Firm, which will be instructed to determine and report to the Parties, within 30 days after such submission, upon such remaining disputed items. The report of the Independent Accounting Firm will be final, binding, and conclusive on the Parties for all purposes. The fees and disbursements of the Independent Accounting Firm will be allocated between Buyer and Seller so that Buyer’s share of such fees and disbursements will be in the same proportion that the aggregate amount of such remaining disputed items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by Buyer (as finally determined by the Independent Accounting Firm) bears to the total amount of such remaining disputed amounts so submitted to the Independent Accounting Firm.

(e) Within five Business Days following the final determination of the Purchase Price pursuant to Sections 3.2(c) and 3.2(d), (i) if the Purchase Price is greater than the Closing Payment Amount, Buyer will pay the difference (adjusted to reflect any payment pursuant to Section 3.2(d)(i)) to Seller; or (ii) if the Purchase Price is less than the Closing Payment Amount, Seller will pay the difference (adjusted to reflect any payment pursuant to Section 3.2(d)(i)) to Buyer. Any amount, together with interest thereon at a rate equal to JPMorgan’s prime rate from time to time in effect, from the Closing Date to the date of payment, to be paid under this Section 3.2(e) will be paid in cash by wire transfer of immediately available funds to the account specified by the Party receiving payment.

3.3 Allocation of Purchase Price. All amounts constituting consideration within the meaning of, and for the purposes of, Section 1060 of the Code and the regulations thereunder shall be allocated among the Purchased Assets in the manner required by Section 1060 of the Code and the regulations thereunder and all applicable Laws. Within 60 calendar days after the Closing Date, Seller shall provide Buyer with a proposed schedule (the “Allocation Schedule”) allocating all such amounts as provided herein. The Allocation Schedule shall become final and binding on the parties hereto 15 calendar days after Seller provides such schedule to Buyer, unless Buyer objects in writing to Seller, specifying the basis for its objection and preparing an alternative allocation. If Buyer does object, the Parties shall in good faith attempt to resolve the dispute within 15 calendar days of written notice to Seller of Buyer’s objection. Any such resolution shall be final and binding on the parties hereto. Any unresolved disputes shall be promptly submitted to the Independent Accounting Firm for determination, which shall be final and binding on the parties hereto. Buyer and Seller will each pay one-half of the fees and expenses of the Independent Accounting Firm. Buyer and Seller shall cooperate with each other and the Independent Accounting Firm in connection with the matters contemplated by this Section 3.3, including, without limitation, by furnishing such information and access to books, records (including, without limitation, accountants work papers), personnel and properties as may be reasonably requested. Each of the parties hereto agrees to (a) prepare and timely file all Tax Returns, including IRS Form 8594 (and all supplements thereto) in a manner consistent with the Allocation Schedule as finalized and (b) act in accordance with the Allocation Schedule for all tax purposes. The Parties hereto will revise the Allocation Schedule to the extent necessary to reflect any post-Closing payment made pursuant to or in connection with this Agreement. In the case of any such payment, Seller shall propose a revised Allocation Schedule, and the parties hereto shall follow the procedures outlined above with respect to review, dispute and resolution in respect of such revision.

3.4 Proration.

(a) All Taxes, utility charges, and similar items customarily prorated, including those listed below, to the extent relating to the Business or the Purchased Assets will be prorated as of the Effective Time, with Seller liable to the extent such items relate to any period on or prior to the Effective Time, and Buyer liable to the extent such items relate to any period after the Effective Time. Such items to be prorated will include:

(i) personal property and real property Taxes, assessments, franchise fees, and other similar charges, including charges for water, telephone, electricity, and other utilities;

(ii) any permit, license, registration, and compliance assurance fees or other fees with respect to any Transferable Permits, Transferable Environmental Permit or other Purchased Asset; and

(iii) rents under the Real Property Leases or any personal property leases included in the Purchased Assets.

(b) In connection with any real or personal property Tax prorations, including installments of special assessments, as between Buyer and Seller, Seller will be responsible for an amount equal to the amount of the current real or personal property Tax or installment of special assessments, as the case may be, multiplied by a fraction, in each instance (i) the numerator of which is the number of days from the first day of the Taxable Period or assessment period in which the Closing Date occurs to the Closing Date, and (ii) the denominator of which is the total number of days in the Taxable Period or assessment period in which the Closing Date occurs and Buyer will be responsible to reimburse Seller for the balance of such amount. In connection with any other prorations, in the event that actual amounts are not available at the Closing Date, the proration will be based upon the Taxes, assessments, charges, fees, or rents for the most recent period completed prior to the Closing Date for which actual Taxes, assessments, charges, fees, or rents are available. All prorations will be based upon the most recent available Tax rates, assessments, and valuations. Any prorations will be made so as to avoid duplication of any items, and will not include items which are otherwise taken into account in determining the Purchase Price, including the Adjustment Amount. Seller shall have the sole right to contest, compromise or request and obtain refunds with respect to all real and personal property Taxes allocable to periods ending on or prior to the Closing Date or that are the responsibility of Seller pursuant to this Section 3.4(b) (“Seller Property Taxes”).

(c) The proration of all items under this Section 3.4 will be recalculated by Buyer within 60 days following the date upon which the actual amounts become available to Buyer. Buyer will notify Seller promptly of such recalculated amounts, and will provide Seller with all documentation relating to such recalculations, including tax statements and other notices from third parties. The Parties will make such payments to each other as are necessary to reconcile any estimated amounts prorated as of the Effective Time with the final amounts to be prorated. Seller and Buyer agree to furnish each other with such documents and other records as may be reasonably requested in order to confirm all proration calculations made pursuant to this Section 3.4.

7.2 Access to Information.

(a) Between the date of this Agreement and the Closing Date, Seller will, during ordinary business hours and upon reasonable notice, (i) give Buyer, Buyer’s Representatives and its financing providers (including prospective providers of financing) and their respective counsel, auditors and other authorized representatives reasonable access to the Purchased Assets to which Buyer is not denied access by Law and to which Seller has the right to grant access without the consent of any other Person (and in the case where consent of another Person is required, only on such terms and conditions as may be imposed by such other Person); (ii) permit Buyer, Buyer’s Representatives and its financing providers

(including prospective providers of financing) and their respective counsel, auditors and other authorized representatives to make such reasonable inspections thereof as they may reasonably request; (iii) furnish Buyer, Buyer’s Representatives and its financing providers (including prospective providers of financing) and their respective counsel, auditors and other authorized representatives with such financial and operating data and other information with respect to the Business as such Persons may from time to time reasonably request; (iv) furnish Buyer with a copy of each material report, schedule, or other document relating to the Business filed by Seller with, or received by Seller from, any Governmental Entity; (v) give Buyer and Buyer’s Representatives reasonable access to each member of the Transition Advisory Team; and (vi) give Buyer and Buyer’s Representatives reasonable access to such personnel, information and assets of Seller as may be necessary to fulfill Buyer’s obligations under Section 3(a)(iv) of the Transition Services Agreement; provided, however, that (A) any investigation permitted by this Section 7.2 (a) will be conducted in such a manner as not to interfere unreasonably with the operation of the Business or any other Person, (B) Seller will not be required to take any action which would constitute a waiver of the attorney client privilege, and (C) Seller need not supply Buyer with any information which Seller is under a contractual or other legal obligation not to supply. Notwithstanding anything in this Section 7.2 to the contrary, (x) Buyer will not have access to personnel and medical records if such access could, in Seller’s good faith judgment, subject Seller to risk of liability or otherwise violate the Health Insurance Portability and Accountability Act of 1996, and (y) any investigation of environmental matters by or on behalf of Buyer will be limited to visual inspections and site visits commonly included in the scope of “Phase 1” level environmental inspections, and Buyer will not have the right to perform or conduct any other sampling or testing at, in, on, or underneath any of the Purchased Assets.

(b) Unless and until the transactions contemplated hereby have been consummated, each Party will, and will cause its Affiliates and Buyer’s Representatives and potential financing sources or Seller’s Representatives, as applicable, to, hold in strict confidence and not use or disclose to any other Person all Confidential Information. As to each Party, “Confidential Information” means all information in any form heretofore or hereafter obtained from either Party in connection with such Party’s evaluation of the Business, the negotiation of this Agreement, or the performance of the covenants and agreements of this Agreement, whether pertaining to financial condition, results of operations, methods of operation or otherwise, other than information that (i) was already in such receiving Party’s or its Representatives’ or, in the case of Buyer, its potential financing sources’ possession; provided, that such information is not known by such receiving Party, after due inquiry, to be subject to another confidentiality agreement with or other obligation of secrecy to the other Party or any other party, (ii) subsequently becomes generally available to the public other than as a result of a disclosure by such receiving Party or its Representatives or, in the case of Buyer, its potential financing sources in breach of this Section 7.2(b) or the Confidentiality Agreement or (iii) subsequently becomes available to such receiving Party on a non-confidential basis from a source other than the other Party or its Representatives or, in the case of Buyer, its potential financing sources; provided, that such source is not known by such receiving Party, after due inquiry, to be bound by a confidentiality agreement with or other obligation of secrecy or non-disclosure to the other Party or any other

party. Notwithstanding the foregoing, each Party, its Affiliates, its Representatives or, in the case of Buyer, its potential financing sources, may disclose Confidential Information to the extent that such information is required to be disclosed by it by Law, in connection with any proceeding by or before a Governmental Entity, including any disclosure, financial or otherwise, required to comply with any Required Regulatory Approvals or if requested by any Governmental Entity having jurisdiction over the Party, its Affiliates, its Representatives or, in the case of Buyer, its potential financing sources. In the event that a Party receives a request (whether by oral questions, interrogatories, requests for documents in legal proceedings, under the terms of a subpoena or order issued by a court or governmental body or other similar process or otherwise pursuant to applicable regulation (including stock exchange) to disclose all or any part of the Confidential Information, such Party agrees, and shall cause its Representatives, to promptly notify the other Party of the existence, terms and circumstances surrounding such a request, so that such other Party may seek, at its expense, an appropriate protective order and/or waive such notifying Party’s compliance (or its Representatives’ compliance, as the case may be) with the provisions of this Section 7.2(b) and the Confidentiality Agreement (and if such Party seeks such an order, to provide such cooperation as such Party shall reasonably request). If disclosure of such information is required in the opinion of a Party’s counsel (or its Representatives’ counsel, as the case may be), who shall be reasonably satisfactory to the other Party, the receiving Party agrees, and shall cause its Representatives to, exercise commercially reasonable efforts to obtain, at the other Party’s expense, an order or other reliable assurance that confidential treatment will be accorded to such of the disclosed information which the other Party so designates. In addition, if a protective order is not obtained, such receiving Party will furnish only that portion of the Confidential Information which is legally required. In any event, any Party or its Representatives may disclose Evaluation Material legally required to be disclosed without liability hereunder. If the transactions contemplated hereby are not consummated, each Party will promptly return to the other Party all copies of any Confidential Information, including any materials prepared by such Party or Buyer’s Representatives or Seller’s Representatives, as applicable, incorporating or reflecting Confidential Information, and an officer of such Party will certify in writing compliance by such Party with the foregoing.

(c) Seller agrees that for the thirty (30) month period immediately following the Closing Date, Seller will, and will cause its Affiliates and Seller’s Representatives to, hold in strict confidence and not disclose to any other Person all Confidential Business Information. “Confidential Business Information” means all commercially sensitive information in any form heretofore or hereafter obtained by Seller to the extent relating to the Business or the Purchased Assets, whether pertaining to financial condition, results of operations, methods of operation or otherwise, other than information which is in the public domain through no violation of this Agreement. Notwithstanding the foregoing, Seller may disclose Confidential Business Information to the extent that such information is required to be disclosed under contracts existing as of the Closing Date, by Law, or in connection with any proceeding by or before a Governmental Entity, including any disclosure, financial or otherwise, required to comply with any rules of the Securities and Exchange Commission (the “SEC”) or Required

Regulatory Approvals. In the event that Seller believes any such disclosure is required by Law or in connection with any proceeding by or before a Governmental Entity, Seller will give Buyer notice thereof as promptly as possible and will cooperate with Buyer in seeking any protective orders or other relief as Buyer may determine to be necessary or desirable. In no event will Seller make or permit to be made any disclosure of Confidential Business Information other than to the extent Seller determines in good faith to be required pursuant to SEC rules, or rules governing required disclosure in other regulatory proceedings, or its legal counsel has advised is required to comply with the terms of a contract existing as of the Closing Date or required by Law, or is required in connection with any proceeding by or before a Governmental Entity, and Seller will use its commercially reasonable efforts to assure that any Confidential Business Information so disclosed is protected from further disclosure.

(d) Buyer agrees that, without Seller’s written consent, except as otherwise provided for in this Agreement, for two years from date of this Agreement, neither it nor any of its Affiliates will, directly or indirectly, (i) solicit any suppliers, customers and/or any other person with whom Seller has a business relationship, other than in the ordinary course of business or (ii) solicit for employment or hire (or cause or seek to cause to leave the employ of Seller) any person with whom Buyer had contact or who became known to Buyer as a result of the provision of the Confidential Information and who is an employee of Seller or any subsidiary thereof; provided, however, that the foregoing clause (ii) of this Section 7.2(d) shall not preclude Buyer from hiring individuals contacted through good faith generalized solicitations for employees through advertisements which utilize a public medium and are not directly or indirectly targeted at employees of Seller or any of its Affiliates or from hiring any employee of Seller or its Affiliates who has been terminated by Seller or its Affiliates prior to commencement of employment discussions between Buyer and such employee.

(e) Buyer and Seller hereby terminate the Confidentiality Agreement. The provisions of Sections 7.2(b) and 7.2(d) will survive for a period of two years following the earlier of (i) the Closing Date or (ii) the termination of this Agreement, except that if the Closing occurs, the provisions of Section 7.2(b) will expire with respect to Buyer and its possession or use of any information exclusively related to the Purchased Assets and the Business.

(f) For a period of seven years after the Closing Date, each Party and its representatives will have reasonable access to all of the books and records relating to the Business or the Purchased Assets, including the Documents and all Transferred Employee Records, in the possession of the other Party to the extent that such access may reasonably be required by such Party in connection with the Assumed Obligations or the Excluded Liabilities, or other matters relating to or affected by the operation of the Business and the Purchased Assets or, in the case of access by Buyer and its representatives, in connection with the preparation of audited financial statements as of or for any period ending on a date prior to the Effective Time. Such access will be afforded by the Party in possession of such books and records upon receipt of reasonable advance notice and during normal business hours;

provided, however, that (i) any review of books and records will be conducted in such a manner as not to interfere unreasonably with the operation of the business of any Party or its Affiliates, (ii) no Party will be required to take any action which would constitute a waiver of the attorney-client privilege, and (iii) no Party need supply the other Party with any information which such Party is under a contractual or other legal obligation not to supply. The Party exercising the right of access hereunder will be solely responsible for any costs or expenses incurred by it pursuant to this Section 7.2(f). If the Party in possession of such books and records desires to dispose of any such books and records at any time, such Party will, prior to such disposition, give the other Party a reasonable opportunity at such other Party’s expense to segregate and take possession of such books and records as such other Party may select. Notwithstanding anything to the contrary in this Section 7.2(f), following the expiration of the seven year period set forth above, each Party agrees to provide reasonable access to all of the books and records relating to the Business or the Purchased Assets, including the Documents and all Transferred Employees Records, in the possession of the other Party to the extent required to respond to any proceeding before the NMPRC or the FERC.

(g) Not later than June 30, 2008, at Buyer’s expense, Seller will prepare and deliver to Buyer an audited statement of income of the Business for the fiscal year ended December 31, 2007. In the course of preparing such audited statement of income, any judgment or determination as to materiality shall be made in light of the Business and not in light of the operations of Seller taken as a whole.

(h) Not later than 30 days following the date hereof, Seller will prepare and deliver to Buyer Schedule 7.2(h), which schedule shall include a list of each Business Agreement under which Seller has incurred Disclosed Indebtedness in an aggregate principal amount in excess of $100,000. Not later than ten days prior to the Closing, Seller will prepare and deliver to Buyer a supplemented Schedule 7.2(h) pursuant to Section 7.8, which schedule shall include a list of each such Business Agreement as of such date.

7.3 Expenses. Except to the extent specifically provided herein, and irrespective of whether the transactions contemplated hereby are consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby will be borne by the Party incurring such costs and expenses. For the avoidance of doubt, Buyer will be solely responsible for payment of (i) all filing fees in connection with any Required Regulatory Approvals, and (ii) all other filing, recording, transfer, or other fees or charges of any nature payable pursuant to any provision of Law or any Order or Franchise in connection with the sale, transfer, and assignment of the Purchased Assets and the Assumed Obligations.

7.4 Further Assurances; Procedures with Respect to Certain Agreements and other Assets.

(a) Subject to the terms and conditions of this Agreement, each of the Parties will use commercially reasonable efforts to take, or cause to be taken, all action, and to do, or cause to be done, all things necessary, proper, or advisable to consummate and make effective the transactions contemplated hereby, including using commercially reasonable efforts to obtain satisfaction of the conditions precedent to each Party’s obligations hereunder within its reasonable control. Neither Party will, without the prior written consent of the other Party, take any action which would reasonably be expected to prevent or materially impede, interfere with or delay the transactions contemplated by this Agreement (including the obtaining of the Required Regulatory Approvals). From time to time on or after the Closing Date, Seller will, at its own expense, execute and deliver such documents to Buyer as Buyer may reasonably request in order to more effectively consummate the transactions contemplated hereby. From time to time after the date hereof, Buyer will at its own expense (i) execute and deliver such documents to Seller as Seller may reasonably request in order to more effectively consummate the transactions contemplated hereby and (ii) without being required to make any payment to any third party or to incur any economic burden, cooperate reasonably with Seller in connection with Seller obtaining any releases or discharges of Seller from any of the Assumed Obligations; provided, however, that if in the course of obtaining any release or discharge contemplated by clause (ii) of this sentence any third party shall require any payment or other form of consideration to be made or delivered by Buyer, Seller agrees to fully reimburse Buyer therefor promptly following notice thereof.

(b) Seller has easements, license agreements (including railroad crossing rights), rights-of-way, and leases for rights-of-way, some of which relate exclusively to the Business and Purchased Assets (the “Easements”) and others of which relate to both the Business and Purchased Assets and Seller’s Electric Business or other businesses (the “Shared Easements”). At the Closing, Seller will convey and assign to Buyer, subject to the obtaining of any necessary consents, (i) by the Assignment of Easements, all Easements, and (ii) by separate sub-easement, partial assignment or other document, sufficient rights under the Shared Easements to permit Buyer to use the same, as presently used by Seller with respect to the Business, on a nonexclusive basis (the “Shared Easement Rights”).

(c) To the extent that Seller’s rights under any asset described in Section 2.1(b), 2.1(c), 2.1(h), 2.1(i), 2.1(l), 2.1(m), 2.1(n), 2.1(p), 2.1(r), 2.1(u) or 2.1(y) (each, a “Consent Asset”) may not be assigned without the consent of another Person which consent has not been obtained, this Agreement will not constitute an agreement to assign the same if an attempted assignment would constitute a breach thereof or be unlawful. Seller will use its commercially reasonable efforts (without being required to make any payment to any third party or to incur any economic burden) to obtain any such required consent as promptly as possible. Upon receipt of the consent required to transfer a Consent Asset, such Consent Asset shall become a Purchased Asset and all liabilities and obligations under such Consent Asset shall constitute Assumed Obligations. Buyer agrees to cooperate with Seller in its efforts to obtain any such consent (including the submission of such financial or other information concerning Buyer and the execution of any assumption agreements or similar documents reasonably requested by a third party) without being required to make any payment to any third party or to incur any economic burden (other than the assumption of Seller’s obligations under the applicable Consent Asset). Seller and Buyer agree that if any consent to an assignment of any such asset is not obtained or if any attempted assignment would be ineffective or would impair Buyer’s rights and obligations under such Consent Asset so that Buyer would not acquire the benefit of all such rights and obligations, then (i) at the Closing the Parties will, to the maximum extent permitted by Law and such Consent Asset, enter into such arrangements with each other on commercially reasonable terms as are reasonably necessary to provide Buyer with the benefits and obligations of such Consent Asset from and after the Effective Time, and (ii) all liabilities and obligations under such Consent Asset shall not constitute Assumed Obligations.

(d) Buyer and Seller agree that at Closing, Buyer and Seller will enter into one or more back-to-back Contracts, in customary form, with appropriate credit terms, pursuant to which Seller will transfer to Buyer, and Buyer will acquire, the economic benefits and risks of Seller’s entire portfolio at the Effective Time of GSP Financial Hedges, such that under the PGAC the customers of the Business and the Business remain in the same economic position immediately following the entry into of such new Contracts as immediately preceding the Effective Time. Any transaction costs incurred as a result of such transactions will be borne by the Party that performs the transaction.

(e) The agreements set forth on Schedule 7.4(e) (the “Shared Agreements”) will be governed by this Section 7.4(e) and are not Business Agreements. Seller’s rights and obligations under the Shared Agreements, to the extent such rights and obligations relate to the Business, are described on Schedule 7.4(e), and are referred to herein as the “Allocated Rights and Obligations.” Unless Seller elects to enter into Other Arrangements, the Parties agree to cooperate with each other and use commercially reasonable efforts to enter into agreements with the other party or parties to each Shared Agreement providing for (i) assignment to and assumption by Buyer, effective from and after the Effective Time, of the Allocated Rights and Obligations, and (ii) retention by Seller of all rights and obligations of Seller under the Shared Agreements other than the Allocated Rights and Obligations (such agreements set forth in (i) and (ii) being referred to as “Substitute Arrangements”); provided, that neither Seller nor Buyer will be obligated to enter into or agree to any such Substitute Arrangements unless such Substitute Arrangements have the effect of transferring to Buyer the Allocated Rights and Obligations (and reserving to Seller the rights and obligations which are not Allocated Rights and Obligations) on a fair and equitable basis, as determined in the reasonable discretion of Seller and Buyer. In connection with the foregoing, the Parties agree, as reasonably requested, to submit such financial or other information concerning themselves, and to execute such assumption agreements or similar documents reasonably requested by a third party; provided, that neither Party will be required to make any payment to any third party or to incur any economic burden (other than the assumption of the Allocated Rights and Obligations by Buyer, and the retention of the other rights and obligations under the Shared Agreements by Seller). In the event that (x) the Parties are unable to enter into Substitute Arrangements with respect to a Shared Agreement in accordance with the foregoing, or (y) Seller notifies Buyer that it elects not to pursue Substitute Arrangements with respect to such Shared Agreement, then in either case at the Closing the Parties will, to the maximum extent permitted by Law and such Shared Agreement, enter into such arrangements with each other on commercially reasonable terms as are reasonably necessary to provide Buyer with the benefits and obligations of the Allocated Rights and Obligations under such Shared Agreement, including pursuant to the Transition Services Agreement, with Seller retaining the other benefits and obligations under such Shared Agreement from and after the Effective Time (the “Other Arrangements”). In the event the entry into any Substitute Arrangement or Other Arrangement contemplated by this Section 7.4(e) gives rise to any filing, notice, reporting or any other obligation of Buyer or Seller, including any obligation to appear before, make application or provide information, to the NMPRC or any other regulatory entity exercising jurisdiction over Seller or the Business (a “Regulatory Entity”), Buyer and Seller will use their commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper, or advisable to satisfy any such obligation.

(f) Seller from time to time provides collateral or other security to certain other Persons in connection with the Business pursuant to certain Business Agreements and Shared Agreements. Seller and Buyer agree to use commercially reasonable efforts to cause such collateral or other security to be returned to Seller at the Closing (including in the case of a letter of credit a return of the letter of credit to Seller), or released (in the case of other credit support previously provided by Seller) at the Closing. In the event that such collateral or other security is not returned to Seller or otherwise released at the Closing, Buyer will (i) pay to Seller an amount equal to any cash collateral posted by Seller; and (ii) in the case of a letter of credit, provide to Seller a back-up letter of credit in the same amount and for a period expiring no earlier than 10 days following the expiration of the letter of credit previously provided by Seller. Buyer agrees to provide substitute collateral and other security with respect to such Business Agreements and Shared Agreements in amounts and on terms of no less quality than previously provided by Seller. The provisions of this Section 7.4(f) will apply only to collateral or other security provided in connection with (i) Business Agreements assigned to Buyer at Closing, and (ii) Shared Agreements to the extent such collateral or other security is related to the Allocated Rights and Obligations assigned to Buyer at Closing under such Shared Agreements.

(g) Customers of Seller from time to time provide collateral or other security to Seller in connection with the Business in the form of surety or similar agreements (the “Surety Instruments”). Buyer acknowledges and agrees that to the extent any such Surety Instruments are not related exclusively to the Business (“Seller Common Surety Instruments”) such Seller Common Surety Instruments are not part of the Purchased Assets. If any Seller Common Surety Instrument disproportionately secures obligations owed by a customer of the Electric Business, Seller will upon request of Buyer release such security to such customer to the extent appropriate to eliminate such overcollateralization.

(h) Seller has tower lease and sub-lease agreements, licenses issued by the FCC, franchise agreements, wireline telecommunications facilities, dark fiber agreements including Indefeasible Right of Use Agreements, easements and rights-of-way, and leases for rights-of-way, some of which relate exclusively to the Business and Purchased Assets (the “Telecommunications Network Elements”) and others of which relate to both the Business and Purchased Assets and Seller’s Electric Business or other businesses (the “Shared Telecommunications Network Elements”). At the Closing, Seller will convey and assign to Buyer, subject to the obtaining of any necessary consents, (i) by assignment or other appropriate document, all Telecommunications Network Elements, and (ii) by separate sub-lease, sub-easement, management agreement, private carriage agreement or other appropriate document, sufficient rights under the Shared Telecommunications Network Elements to permit Buyer to use the same, as presently used by Seller with respect to the Business, on a nonexclusive basis for no more than two (2) years following Closing (the “Shared Telecommunications Network Element Rights”).

(i) Following the Closing, each Party will promptly remit to the other any payments such Party receives that are in satisfaction of any rights or assets belonging to the other Party.

Each Party will consult with the other prior to issuing, and will consider in good faith any comments by the other to or in respect of, any public announcement, statement, or other disclosure with respect to this Agreement or the transactions contemplated hereby, except as may be required by Law or stock exchange rules and provided that any such public announcement, statement, or other disclosure issued by Buyer will be subject to Section 7.2(b).

7.6 Consents and Approvals.

(a) Seller and Buyer will each file or cause to be filed with the Federal Trade Commission and the United States Department of Justice, Antitrust Division any notifications required to be filed under the HSR Act and the rules and regulations promulgated thereunder with respect to the transactions contemplated hereby.

Seller and Buyer each will have the right to review in advance all characterizations of the information relating to it or the transactions contemplated by this Agreement which appear in any filing made by the other in connection with the transactions contemplated hereby.

(c) In the course of obtaining, renewing or securing Franchises as may be deemed necessary by the Parties in connection with the transactions contemplated herein, (i) Buyer shall not be required to take any action, and Seller shall not take or cause to be taken or agree to commit Buyer to take any action, in any such case individually or in the aggregate which would (A) materially impair the ability of Buyer to operate the Business immediately following Closing in a manner substantially similar to that prevailing with respect to the Business immediately prior to the date hereof or (B) impose any additional substantially burdensome condition on Buyer and (ii) Seller shall not be required to take any action, and Buyer shall not take or cause to be taken or agree to commit Seller to take any action, in any such case individually or in the aggregate which would (A) materially impair the ability of Seller to operate the Electric Business immediately following Closing in a manner substantially similar to that prevailing with respect to the Electric Business immediately prior to the date hereof or (B) impose any additional substantially burdensome condition on Seller. Any failure or refusal by a Governmental Entity to renew or award any such Franchise will not constitute a breach of this Agreement by either Party.

(d) In connection with applications and other filings for the Required Regulatory Approvals, and the prosecution of any pending regulatory proceedings material to the Business, Buyer and Seller shall jointly, and on an equal basis, coordinate the overall development of the positions to be taken and the regulatory actions to be requested in such applications and filings for approval of the sale by Seller and the purchase by Buyer of the Purchased Assets and the Business, of all other matters contemplated by this Agreement which require regulatory approval and of all other regulatory matters incidental thereto which are to be addressed in such applications and filings.

(e) In connection with any communications, meetings, or other contacts, formal or informal, oral or written, with any Governmental Entity in connection with the transactions contemplated hereby or any such declaration, filing, registration, notice, authorization, consent, or approval, each Party agrees: (i) to inform the other in advance of any such communication, meeting, or other contact which such Party proposes or intends to make, including the subject matter, contents, intended agenda, and other aspects of any of the foregoing; (ii) to consult and cooperate with the other Party, and to take into account the comments of such other Party in connection with any of the matters covered by Section 7.6(e)(i); (iii) to arrange for representatives of the other Party to participate to the maximum extent possible in any such communications, meetings, or other contacts; (iv) to notify the other Party of any oral communications with any Governmental Entity relating to any of the foregoing; and (v) to provide the other Party with copies of all written communications with any Governmental Entity relating to any of the foregoing.

7.8 Supplements to Schedules. Prior to the Closing Date, Seller may supplement or amend the Schedules furnished by it under this Agreement except for Schedule 7.1; provided, however, that the new disclosures made in any supplement shall not have any effect on the determination of the satisfaction of the conditions to Closing under Article VIII or any of Buyer’s rights and claims to indemnification under Article IX.

7.9 Employees and Employee Benefits.

(a) From and after the Effective Time, with respect to the Transferred Employees, Buyer will recognize the union locals set forth on Schedule 7.9(a) (the “Locals”) as the exclusive bargaining representatives of the bargaining units set forth on Schedule 7.9(a) that include Transferred Employees. Buyer will assume the Collective Bargaining Agreements, with respect to the Transferred Employees, at Closing and will provide to the Transferred Employees covered thereby benefits consistent with the terms thereof in addition to the other benefits that Buyer is obligated to provide to Transferred Employees under this Section 7.9.

(b) Buyer shall make offers of employment to Business Employees and Designated Employees in accordance with the following provisions:

(i) Buyer agrees to provide written offers of employment to the Business Employees no later than 30 Business Days prior to the Closing Date and to hire the Business Employees who wish to accept the offers of employment. All offers of employment will be conditioned on the occurrence of the Closing and will remain open for a period expiring no earlier than 20 Business Days prior to the Closing Date.

(ii) Buyer agrees to provide written offers of employment to the Designated Employees in accordance with Section 5(b) of the Transition Services Agreement. An offer of employment by Buyer pursuant to this Section 7.9(b)(ii) shall not be considered to be a violation of Section 7.2(c).

(iii) Any Business Employees or Designated Employees who accept such offers of employment shall be considered to be “Transferred Employees.”

(c) Buyer shall provide to Seller copies of all written offers of employment made to the Business Employees within five days of providing such written offers to the Business Employees. At least seven days prior to the Effective Time, Buyer shall notify Seller in writing of the Business Employees who have accepted offers of employment with Buyer.

(d) Buyer agrees to employ the Transferred Employees on terms that are (i) substantially comparable in the aggregate to the Transferred Employees to their current employment terms with respect to salary, annual bonus opportunity, base hours, and vacation (excluding for this purpose any benefits, enhancements or payments that are contingent upon a change in control or similar transaction) and (ii) substantially comparable in the aggregate with respect to benefits provided to the Transferred Employees (including medical, retirement, and severance benefits and excluding for this purpose any benefits, enhancements or payments that are contingent upon a change in control or similar transaction and the value of equity incentives) pursuant to Benefit Plans of Seller in effect as of the date hereof. Except as provided in Section 7.9(f), Buyer’s obligations pursuant to this Section 7.9(d) shall continue for a period of one year following the Effective Time.

(e) From and after the Transfer Date, the employment of the Transferred Employees with Seller or Seller’s Affiliates will terminate and the Transferred Employees will not accrue any additional benefits under any Benefit Plan. Except as provided in Section 7.9(f), Buyer shall not assume any of the Benefit Plans and shall have no obligations or liabilities with respect to the Benefit Plans. Seller or Seller’s Affiliates will pay to each Transferred Employee all salary or other compensation or employment benefits (including any accrued paid-time off) which has accrued to such Transferred Employee prior to the Transfer Date. Buyer or Buyer’s affiliates will pay to each Transferred Employee all salary or other compensation or employment benefits which accrue to such Transferred Employee from and after the Transfer Date, at such times as provided under the terms of the applicable compensation or benefit programs.

(f) Buyer hereby assumes all liabilities, obligations, and responsibilities of Seller and Seller’s Affiliates to provide post-retirement health benefits under the Benefit Plans set forth on Schedule 7.9(f) (“Post-Retirement Welfare Benefits”) to any Grandfathered Active Employee or his or her spouse or other eligible dependents. For this purpose a “Grandfathered Active Employee” is any Transferred Employee who, as of the Transfer Date, satisfied the eligibility requirements for Post-Retirement Welfare Benefits under the applicable Benefit Plan sponsored by Seller. Included within Schedule 7.9(f) is a list of all Business Employees who are currently eligible for Post-Retirement Welfare Benefits. At Closing, Seller will provide Buyer with an updated Schedule 7.9(f) that lists the Business Employees and Designated Employees who as of Closing are eligible for Post-Retirement Welfare Benefits. Seller, Seller’s Affiliates and the Benefit Plans shall not have any liability on or after the Transfer Date for any Post-Retirement Welfare Benefits of any Grandfathered Active Employee or his or her spouse or other eligible dependents. Prior to the Closing Date, Buyer shall establish a new welfare benefit plan or amend an existing welfare benefit plan (in either case the “Successor Retiree Welfare Plan”) which shall expressly assume all of the liabilities, obligations, and responsibilities of Seller, Seller’s Affiliates and any Benefit Plan to provide Post-Retirement Welfare Benefits to Grandfathered Active Employees and their spouses and eligible dependents. Such liabilities, obligations and responsibilities will be automatically transferred to the Successor Retiree Welfare Plan as of the Transfer Date of each Grandfathered Active Employee.

(i) The Successor Retiree Welfare Plan will recognize all Grandfathered Active Employee’s service with Seller or Seller’s Affiliates prior to the Transfer Date of the Grandfathered Active Employee for purposes of determining Post-Retirement Welfare Benefits. The Successor Retiree Welfare Plan also shall provide the Grandfathered Active Employees and their spouses and eligible dependents with Post-Retirement Welfare Benefits that are comparable to, or more favorable, in the aggregate than those Post-Retirement Welfare Benefits provided to such Grandfathered Active Employees and their spouses and eligible dependents by Seller and the Benefit Plans immediately prior to the Closing Date, under cost-sharing structures that are at least as favorable to the Grandfathered Active Employees as the cost-sharing structures in effect from time to time under the Benefit Plans of Seller from which the benefit obligations were assumed by the Successor Retiree Welfare Plan.

(ii) Effective as of the Closing Date and for a period continuing for at least five years thereafter (the “Benefit Continuation Period”), Buyer will continue the Successor Retiree Welfare Plan in compliance with the provisions of Section 7.9(f)(i).

(iii) Following the Benefit Continuation Period, Buyer may amend or terminate the Successor Retiree Welfare Plan and the Post-Retirement Welfare Benefits for the Grandfathered Active Employees and their spouses and eligible dependents; provided, however, that Seller must continue to provide Post-Retirement Welfare Benefits to the Grandfathered Active Employees until the Allocated Retiree Medical Assets transferred to Buyer’s VEBA have been exhausted.

(iv) On or prior to the Closing Date, Buyer will provide evidence reasonably satisfactory to Seller that Buyer has established the Successor Retiree Welfare Plan and is maintaining one or more trusts meeting the requirements of Section 501(c)(9) of the Code (the “Buyer’s VEBA”).

(v) In accordance with the provisions of this Section 7.9(f)(v), Seller will cause one or more of the trusts listed on Schedule 7.9(f) (collectively, “Seller’s VEBA”) to transfer cash (or other assets as the Parties mutually agree) to the Buyer’s VEBA. The transfers will occur on the two dates specified in Section 7.9(f)(vii). Each transfer will be equal to the Allocated Retiree Medical Assets determined as of the last Business Day of the month prior to the date of the transfer. The “Allocated Retiree Medical Assets” as of either date shall equal the product of (a) the total value of the retiree medical assets then held in trusts established by Seller to fund its retiree medical liability for Post-Retirement Welfare Benefits less assets set aside or otherwise allocated to fund the retiree medical liability for Post-Retirement Welfare Benefits for current retirees, times (b) a fraction, the numerator of which is Seller’s retiree medical liability for Post-Retirement Welfare Benefits for the Grandfathered Active Employees and their spouses and eligible dependents and the denominator of which is Seller’s retiree medical liability for Post-Retirement Welfare Benefits for all active participant’s (including the Grandfathered Active Employees) and their spouses and eligible

dependents (determined prior to the transfer). The liabilities will be determined as of the last Business Day of the month prior to the transfer by an actuary selected by Seller and reasonably acceptable to Buyer and in a manner, and on the basis of actuarial and other assumptions, consistent with those used in the most recent actuarial report for Seller’s retiree medical liability for Post-Retirement Welfare Benefits that is provided to Buyer. Buyer and Seller agree that Watson Wyatt or any of its Affiliates shall perform the actuarial services contemplated by this Section 7.9(f)(v). In calculating the Allocated Retiree Medical Assets for the initial transfer, the only Transferred Employees who will be considered to be Grandfathered Active Employees are those with Transfer Dates occurring on or before the later of the date on which the calculation is being made or the Effective Time. In calculating the Allocated Retiree Medical Assets for the second transfer, the only Transferred Employees who will be considered to be Grandfathered Active Employees are those with Transfer Dates occurring after the date as of which the initial transfer is calculated and on or before the date as of which the second transfer is calculated. For purposes of calculating the Allocated Retiree Medical Assets for the second transfer, the liabilities included in the numerator of the fraction used in calculating the amount of the initial transfer will be disregarded both in the numerator and the denominator of the fraction. If Seller concludes, in the exercise of its discretion, that it may not or should not transfer all or any portion of the Allocated Retiree Medical Assets from Seller’s VEBA to Buyer’s VEBA, Seller may elect to make a cash payment to Buyer equal to the difference between the Allocated Retiree Medical Assets and the amount transferred Buyer’s VEBA.

(vi) On or prior to the Closing Date, Seller will provide Buyer with a copy of the Internal Revenue Service letter for each of the trusts listed Schedule 7.9(f) indicating that such trust is exempt from tax pursuant to the requirements of Section 501(c)(9) of the Code.

(vii) The initial transfer to Buyer’s VEBA will occur as soon as administratively practicable after both: (a) Seller either (i) receives a ruling from the Internal Revenue Service that the transfer of the Allocated Retiree Medical Assets to Buyer’s VEBA will not cause Seller’s VEBA to fail to qualify under Section 501(c)(9) of the Code and will not result in taxable income or an excise Tax to Seller or (ii) notifies Buyer in writing that Seller has determined not to apply for such a ruling (and Buyer agrees that no ruling should be required), and (b) Buyer provides evidence reasonably satisfactory to Seller that Buyer’s VEBA satisfies the requirements of Section 501(c)(9) of the Code. The second transfer will occur on the first anniversary of the first transfer or on such other date as may be mutually agreed upon by Seller and Buyer.

(viii) The amounts transferred to Buyer’s VEBA will be dedicated by Buyer exclusively for the funding of Post-Retirement Welfare Benefits for the Grandfathered Active Employees and their spouses and eligible dependents.

(ix) Prior to the Closing, Seller will make contributions to and distributions from Seller’s VEBA and Seller’s other retiree medical funding arrangements from time to time in accordance with Seller’s normal policies and past practice determined by Seller in the exercise of its reasonable discretion.

(g) With respect to any group health plan or program of Buyer or Buyer’s Affiliates in which a Transferred Employee becomes eligible to participate as of the Transfer Date or thereafter, Buyer shall take all commercially reasonable steps to ensure that such Transferred Employee shall (i) receive credit for any deductibles, co-pays or other out-of-pocket expenses paid under the corresponding group health plan or program of Seller or Seller’s Affiliates, and (ii) not be subject to any pre-existing condition limitations to the extent that such pre-existing condition limitation did not apply to such Transferred Employee under the corresponding group health plan or program of Seller or Seller’s Affiliates.

(h) Buyer and Buyer’s Affiliates shall credit each Transferred Employee with the same number of years of service, including partial years of service, as the Transferred Employee is credited with by Seller or Seller’s Affiliates (or any other employer service with which was previously recognized by Seller), under the applicable benefit plan sponsored by Buyer or Buyer’s Affiliate. The service credit required by this Section 7.9(h) shall apply for all purposes under any health, retiree medical, severance, vacation, sick or any similar paid-time off program or other employee welfare benefit plan (as such term is defined in Section 3(1) of ERISA) of Buyer or Buyer’s Affiliates and for purposes of eligibility to participate, vesting, eligibility for a particular form or type of benefit, and benefit accrual (except for benefit accrual under a defined benefit pension plan) under any pension, retirement, savings, or other employee pension benefit plan (as such term is defined in Section 3(2) of ERISA) of Buyer or Buyer’s Affiliates.

(i) Claims of Transferred Employees and their eligible beneficiaries and dependents for medical, dental, prescription drug, life insurance, and/or other welfare benefits (except workers’ compensation or long-term disability benefits) that are incurred before the Transfer Date shall be the responsibility of Seller and Seller’s Affiliates. Claims of Transferred Employees and their eligible beneficiaries and dependents for medical, dental, prescription drug, life insurance, and/or other welfare benefits (except workers’ compensation or long-term disability benefits) that are incurred on or after the Transfer Date shall be the responsibility of Buyer and Buyer’s Affiliates. For purposes of the preceding provisions of this Section 7.9(i), a medical/dental claim shall be considered incurred on the date when the medical/dental services are rendered or medical/dental supplies are provided, and not when the condition arose or when the course of treatment began.

(j) Claims of Transferred Employees and their eligible dependents for health care and dependent care flexible spending account benefits submitted after the Transfer Date for expenses incurred by Transferred Employees prior to the Transfer Date shall be reimbursed by Seller’s or Seller’s Affiliates health care and dependent care flexible spending account plan to the extent permitted in accordance with the terms of such plan. Claims of Transferred Employees and their eligible dependents for health care and dependent care flexible spending account benefits submitted after the Transfer Date for expenses incurred by Transferred Employees subsequent to the Transfer Date shall be reimbursed by Buyer or Buyer’s Affiliates health care and dependent care flexible spending account plan to the extent permitted in accordance with the terms of such plan.

(k) Claims for workers’ compensation or long-term disability benefits arising out of occurrences prior to the Transfer Date shall be the responsibility of Seller and Seller’s Affiliates. Claims for workers’ compensation or long-term disability benefits for Transferred Employees arising out of occurrences on or subsequent to the Transfer Date shall be the responsibility of Buyer and Buyer’s Affiliates.

(l) Transferred Employees shall be permitted to rollover any account balances and associated loans and promissory notes they may have under the PNM Resources, Inc. Retirement Savings Plan to a Section 401(k) Plan sponsored by Buyer or Buyer’s Affiliates.

(m) If within the one year period following the Transfer Date, (i) a Transferred Employee voluntarily terminates his or her employment with Buyer or Buyer’s Affiliates within 30 days after the date upon which the Transferred Employee is notified that the principal place of the Transferred Employee’s employment will be 50 miles or more from the location of such Transferred Employee’s principal place of employment immediately prior to the Transfer Date such that the commute of such Transferred Employee is materially increased, or (ii) the employment of a Transferred Employee is terminated for a reason other than “Cause” (as that term is defined in the PNM Resources, Inc. Non-Union Severance Pay Plan as of the Transfer Date), then Buyer shall provide such terminated Transferred Employee with severance payments and benefits at least equal to the severance payments and benefits that the Transferred Employee would have been entitled to receive as of the Transfer Date if the terminated Transferred Employee had satisfied all of the requirements to receive severance benefits under the PNM Resources, Inc. Non-Union Severance Pay Plan. Whether the terminated Transferred Employee’s severance payments and benefits would have been equal to the “Regular Severance Benefits” or the “Enhanced Severance Benefits” (as those terms are defined in the PNM Resources, Inc. Non-Union Severance Pay Plan) provided by the PNM Resources, Inc. Non-Union Severance Pay Plan will depend on whether the terminated Transferred Employee signs a release that is reasonably acceptable to Buyer.

(n) Buyer expressly agrees that it assumes all obligations to provide any required notice under the WARN Act, or other applicable Laws, and to pay all severance payments, damages for wrongful dismissal and related costs, with respect to the termination of any Transferred Employee employed by Buyer or Buyer’s Affiliates that occurs on or after the Closing Date.

(o) Seller and Seller’s Affiliates shall be responsible for compliance with and liability under Section 4980B of the Code and Sections 601 through 608 of ERISA (“COBRA”) with respect to any COBRA-qualifying events that occur on or prior to the Closing Date to the extent mandated by COBRA with respect to the Business Employees, Designated Employees, Seller’s former employees and the dependents of both of the foregoing. Buyer shall be responsible for compliance with and liability under COBRA with respect to any COBRA-qualifying events that occur after the Transfer Date with respect to the Transferred Employees, and with respect to the dependents of such Transferred Employees.

(p) Nothing in this Agreement shall preclude Seller or Seller’s Affiliates, in its sole discretion, from implementing any retention or other benefit programs, at Seller’s cost, for the benefit of any group of Business Employees or any individuals that it deems appropriate.

(q) During the period from the date of this Agreement until the Closing Date, Seller will work in good faith with Buyer, at Buyer’s cost, to develop retention or other benefit programs that are reasonably requested by Buyer. Any such retention and other benefit programs implemented shall not be considered to be in effect for any purpose under any other provision of this Agreement, including but not limited to, the representations in Article V.

(r) Nothing herein shall be deemed or construed to (i) give rise to any rights, claims, benefits or causes of action to any Business Employee or Designated Employee or (ii) prevent, restrict or limit Buyer or Seller or their Affiliates from terminating the employment of any Business Employee or Designated Employee or modifying or terminating its pension or other benefit plans, programs or policies from time to time as they may deem appropriate.

7.10 Eminent Domain; Casualty Loss.

(a) If, before the Closing Date, any of the Purchased Assets are taken by eminent domain or condemnation, or are the subject of a pending or, to Seller’s Knowledge, contemplated taking which has not been consummated, Seller will (i) notify Buyer in writing of such fact and (ii) at the Closing assign to Buyer all of Seller’s right, title, and interest in and to any proceeds or payments received, or to be received, in compensation for such taking.

(b) If, before the Closing Date, all or any portion of the Purchased Assets are damaged or destroyed by fire or other casualty, Seller will notify Buyer in writing of such fact and, at the Closing (i) pay to Buyer all proceeds from third-party insurers received by, and assign all of Seller’s right, title, and interest in and to any such insurance proceeds received, or to be received, in compensation for such damage or destruction and (ii) reimburse Buyer for any deductible or self-insured retention amount in connection with such damage or destruction under any such insurance policy; provided, however, that the amounts to be paid by Seller to Buyer under clause (i) above shall be reduced by the amount of proceeds received by Seller and applied with the consent of Buyer to the repair or restoration of the applicable Purchased Asset and the amounts to be reimbursed by Seller under clause (ii) above shall be reduced by the amounts incurred by Seller in connection any such repair or restoration and not paid or reimbursed by such insurance.

7.11 Transitional Use of Signage and Other Materials Incorporating Seller’s Name or other Logos. Buyer acknowledges that Seller has the absolute and exclusive proprietary right to the Seller Marks, all rights to which and the goodwill represented thereby and pertaining thereto are being retained by Seller, and that it will have no ongoing claim or rights in or to the Seller Marks, other than the right to use the Seller Marks for 180 days following the date hereof. Except as set forth in the immediately preceding sentence, Buyer will not use or permit the use of any Seller Marks, and within 180 days following the Closing Date, Buyer will remove or cause the removal the Seller Marks from all signage or other items relating to or used in the Business or the Purchased Assets; provided, however, that, Buyer will not be required to complete the removal of Seller Marks from gas line markers until the one (1) year anniversary of the Closing Date. Except as set forth in this Section 7.11, from and after the Closing Date neither Buyer nor any of its Affiliates will utilize the name “Public Service Company of New Mexico” or any Seller Marks in the conduct of the Business.

7.12 Litigation and Regulatory Support. In the event and for so long as either Party is actively contesting or defending against any third-party Claim in connection with (i) any transaction contemplated under this Agreement or (ii) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction on or prior to the Closing Date involving Seller (or Buyer, as successor in interest to the Business and the Purchased Assets), the other Party will cooperate with the contesting or defending Party and its counsel in the contest or defense, make available its personnel, and provide such testimony and access to its books and records as is reasonably necessary in connection with the contest or defense, all at the sole cost and expense of the contesting or defending Party (unless the contesting or defending Party is entitled to indemnification therefor under Article IX). In addition, in the event that Buyer is involved in any proceeding before the NMPRC or the FERC (or any appeal or other judicial proceeding relating thereto) relating to any obligations (including payment obligations) for which Seller could be liable or responsible under this Agreement, Buyer agrees to consult with Seller concerning such obligations (including the positions taken with respect thereto), to allow Seller to participate in the proceeding to the extent necessary to protect or defend Seller’s interests, and to allow Seller, at Seller’s cost but if necessary in Buyer’s name, to exhaust any appeals available to challenge any appealable decision that is adverse to Seller’s interests in respect of such obligation. The Parties expressly agree that the types of proceedings to which the obligations in the foregoing sentence relate include purchased gas adjustment or gas cost recovery proceedings as well as any other proceedings involving rates charged to customers of the Business. The obligations under this Section 7.12 shall survive the Closing.

7.13 Notification of Customers. As soon as practicable following the Closing, Seller and Buyer will cause to be sent to customers of the Business a notice of the transfer of the customers from Seller to Buyer (the “Customer Notification”). The Customer Notification will contain such information as is required by Law and approved by Buyer and Seller, which approval will not be unreasonably withheld or delayed.

7.14 Title Insurance, Surveys, Estoppel Certificates, and Non-Disturbance Agreements. At Buyer’s option and at Buyer’s sole cost and expense, Buyer may obtain (i) title insurance policies in respect of the Owned Real Property, insuring title to the applicable Owned Real Property as vested in Buyer (free and clear of all Encumbrances other than Permitted Encumbrances), and in form, substance, and amount reasonably satisfactory to Buyer (and without limiting the generality of the foregoing, with all requirements satisfied or waived, with all exceptions deleted, and with all endorsements thereto, to the extent reasonably desired by Buyer); (ii) all surveys desired by Buyer in respect of the Owned Real Property, in form and

substance reasonably satisfactory to Buyer; and (iii) all estoppel certificates and non-disturbance agreements desired by Buyer in respect of any Real Property Leases, in form and substance reasonably satisfactory to Buyer and to the parties providing such certificates and agreements. Seller agrees to cooperate as reasonably requested by Buyer (and at Buyer’s expense) in its efforts to obtain any such items; provided, that Seller shall not be required to make any payment to any third party or incur any economic burden in connection therewith, and provided, further, that Buyer’s obtaining any such item shall not be a requirement of or a condition to the Closing. In addition, with respect to Seller’s cooperation with Buyer’s reasonable requests to obtain title insurance under subsection (i) above, Seller, except to the extent required to satisfy the Closing condition set forth in Section 8.2(f) and as provided by Section 4.3(p), shall not be required to cure any purported defects, cause any exceptions to be deleted, or provide any indemnities, or representations to any title company issuing such title insurance.

7.15 Central or Shared Functions for Transition Period. Seller and Buyer acknowledge that the Business is currently dependent upon the Central or Shared Functions. Seller and Buyer also acknowledge that the Purchased Assets will not include the assets necessary for Buyer to perform such functions and that the Designated Employees are not included in the group identified as the “Business Employees.”

7.16 Post-Closing Insurance. If Seller has any policies of general, excess, umbrella, environmental impairment or pollution insurance with third-party insurance providers (the “Seller Insurance Policies”) that provide coverage in respect of the Assumed Environmental Liabilities, Seller will indemnify Buyer for any Losses incurred by Buyer in respect of the Assumed Environmental Liabilities; provided, however, that such indemnification obligation will be limited to (i) the amount of proceeds actually received by Seller after the Effective Time under the Seller Insurance Policies in respect of the Assumed Environmental Liabilities, less (ii) Seller’s reasonable costs incurred in recovering such proceeds, to the extent allocated by Seller in a fair and equitable manner and otherwise in accordance with Seller’s historical practices to the receipt of the proceeds described in clause (i) of this Section. Seller will use commercially reasonable efforts to maximize the recovery of proceeds after the Effective Time in respect of the Assumed Environmental Liabilities under the Seller Insurance Policies; provided, however, that Seller will not be liable for the failure to recover any specific amount of proceeds, and Seller will be under no obligation to keep any of the Seller Insurance Policies in effect following Closing.

7.17 Financing.

(a) Seller shall, and shall cause its Representatives to, cooperate as reasonably requested by Buyer and take such actions as Buyer may reasonably request in connection with the procurement and consummation of the financing by Buyer or its Affiliates of the transaction contemplated by this Agreement (the “Financing”), which cooperation shall include provision of such information regarding the Business as is reasonably requested by the financial institutions providing the Financing, review and consultation with respect to the preparation of all agreements, offering memoranda and other documentation (including review of schedules for completeness) required in connection with the Financing and attendance

and participation at meetings by telephone and in person with respect to syndication and marketing as is reasonably requested by Buyer; provided, however, that Seller will not be required to pay any commitment or other similar fee or incur any other liability, other than out-of-pocket expenses incidental to such cooperation, in connection with the Financing. To the extent not provided prior to the date of this Agreement, Seller shall deliver to Buyer, within five Business Days of such data being available to Seller’s management, monthly financial data generated by in respect of the operation of the Business by Seller’s internal accounting systems in respect of the Business for use by senior and financial management for any fiscal month ending after the date of the most recently ended fiscal quarter of Seller for which financial statements are available and on or prior to 30 days prior to the Closing Date. The closing of the Financing shall not be a condition to the Closing.

(b) In the event the Equity Commitment Letter is terminated prior to the Closing, Buyer shall promptly obtain a renewal of, or a substitute for, the Equity Commitment Letter on terms and conditions comparable in all material respects to the terms and conditions contemplated in the Equity Commitment Letter or on more favorable terms to Buyer. In the event any portion of the funds to be provided under the Equity Commitment Letter becomes unavailable on terms and conditions comparable in all material respects to the terms and conditions contemplated in the Equity Commitment Letter, Buyer shall arrange to obtain any such portion from alternative sources on comparable or more favorable terms to Buyer. Buyer shall give Seller prompt notice upon becoming aware of any breach by any party of the Equity Commitment Letter or Debt Commitment Letter or any purported termination of the Equity Commitment Letter or Debt Commitment Letter. Buyer shall not permit any material amendment or modification to be made to, or any waiver of any provision or remedy under, the Equity Commitment Letter if such amendment, modification, waiver or remedy reduces the aggregate amount of the funds to be provided under the Equity Commitment Letter or is adverse to the interests of Seller in any other respect.

7.18 Cooperation Regarding Tax Matters. (a) Seller and Buyer agree to cooperate, and shall cause their respective Affiliates, officers, employees, agents, auditors and representatives to cooperate, and to furnish or cause to be furnished to the other, upon request, as promptly as practicable, such information (including access to books and records) and assistance relating to the Business, Purchased Assets and Assumed Obligations as is reasonably necessary for the filing of any Tax Return, the preparation for any Tax audit, the prosecution or defense of any claim, suit or proceeding relating to any proposed Tax adjustment involving the Business. Buyer and Seller shall keep all such information and documents received by them confidential unless otherwise required by Law.

Seller and Buyer agree to give the other reasonable notice prior to transferring, discarding or destroying any such books and records relating to Tax matters.

ARTICLE IX

INDEMNIFICATION

9.1 Survival of Representations and Warranties. The representations and warranties of the Parties contained in this Agreement will survive the Closing and will expire April 15, 2010, except that the representations and warranties in Section 5.14 will survive the Closing and will expire upon the expiration of the applicable statute of limitations.

9.2 Indemnification.

(a) Subject to Section 9.1 and Section 9.4, from and after the Closing, Seller will indemnify, defend, and hold harmless Buyer and its officers, directors, employees, agents and Affiliates (and the officers, directors, employees and agents of such Affiliates (each, a “Buyer Indemnitee”) from and against any and all Claims and Losses (each, an “Indemnifiable Loss”), asserted against or suffered by any Buyer Indemnitee relating to, resulting from, or arising out of (i) any breach by Seller of any covenant or agreement of Seller contained in this Agreement, (ii) any breach by Seller of the representations and warranties of Seller contained in this Agreement, or (iii) the Excluded Liabilities.

(b) Subject to Section 9.1 and Section 9.4, from and after the Closing, Buyer will indemnify, defend, and hold harmless Seller and its officers, directors, employees, agents and Affiliates (and the officers, directors, employees and agents of such Affiliates, (each, a “Seller Indemnitee”) from and against any and all Indemnifiable Losses asserted against or suffered by any Seller Indemnitee relating to, resulting from, or arising out of (i) any breach by Buyer of any covenant or agreement of Buyer contained in this Agreement, (ii) any breach by Buyer of the representations and warranties of Buyer contained in this Agreement, (iii) the Assumed Obligations, or (iv) any and all liabilities and obligations (other than the Excluded Liabilities) to the extent related to the ownership and operation of the Purchased Assets and the Business from and after the Effective Time.

(c) Any Person entitled to receive indemnification under this Agreement (an “Indemnitee”) having a claim under these indemnification provisions will use commercially reasonable efforts to mitigate any Losses, including commercially reasonable efforts to recover all Losses from insurers of such Indemnitee under applicable insurance policies so as to reduce the amount of any Indemnifiable Loss hereunder, and will not take any action specifically excluding from any of its insurance policies any Indemnifiable Losses if Losses of such type are otherwise covered by such policies. The amount of any Indemnifiable Loss will be reduced to the extent that Indemnitee receives any insurance proceeds with respect to an Indemnifiable Loss.

9.3 Indemnification Procedures.

(a) Third Party Claims. If an Indemnitee receives notice of the assertion or commencement of any Claim by any Person who is neither a Party to this Agreement nor an Affiliate of a Party to this Agreement (a “Third Party Claim”) for which the Indemnitee claims a right to indemnification hereunder from the other Party (the “Indemnifying Party”), the Indemnitee will promptly give written notice of such Third Party Claim to the Indemnifying Party. Such notice will describe the nature of the Third Party Claim in reasonable detail and will indicate the estimated amount, to the extent practicable, of the Indemnifiable Loss that the Indemnitee claims it has sustained or may sustain as a result of such Third Party Claim. The Indemnifying Party, at its sole cost and expense, will have the right, upon written notice to the Indemnitee, to assume the defense of the Third Party Claim while reserving its right to contest the issue of whether it is liable to the Indemnitee for any indemnification hereunder with respect to such Third Party Claim.

(b) Defense of Third Party Claims. If the Indemnifying Party assumes the defense of a Third Party Claim pursuant to Section 9.3(a), the Indemnifying Party will appoint counsel reasonably satisfactory to the Indemnitee for the defense of such Third Party Claim, will diligently pursue such defense, and will keep the Indemnitee reasonably informed with respect to such defense. The Indemnitee shall cooperate with the Indemnifying Party and its counsel, including permitting reasonable access to books, records, and personnel, in connection with the defense of any Third Party Claim (provided, that any out-of-pocket costs incurred by the Indemnitee in providing such cooperation shall be paid by the Indemnifying Party). The Indemnitee will have the right to participate in such defense, including appointing separate counsel, but the costs of such participation shall be borne solely by the Indemnitee. The Indemnifying Party will have full authority, in consultation with the Indemnitee, to make all decisions and determine all actions to be taken with respect to the defense and settlement of the Third Party Claim, including the right to pay, compromise, settle, or otherwise dispose of such Third Party Claim at the Indemnifying Party’s expense; provided, that any such settlement will be subject to the prior consent of the Indemnitee, which shall not be unreasonably withheld or delayed. If a firm offer is made to settle a Third Party Claim, which the Indemnifying Party desires to accept and which acceptance requires the consent of the Indemnitee pursuant to the immediately preceding sentence, the Indemnifying Party will give written notice to the Indemnitee to that effect. If the Indemnitee fails to consent to such firm offer within 10 days after its receipt of such notice, and such firm offer involves only the payment of money, the maximum liability of the Indemnifying Party with respect to such Third Party Claim will be the amount of such settlement offer, plus reasonable costs and expenses paid or incurred by the Indemnitee up to the date of such notice for which the Indemnifying Party is otherwise liable. In no event will the Indemnifying Party have authority to agree to any relief binding on the Indemnitee other than the payment of money damages by the Indemnifying Party unless agreed to by the Indemnitee, which agreement will not be unreasonably withheld or delayed.

(c) Failure of Indemnifying Party to Assume Defense. If the Indemnifying Party does not assume the defense of a Third Party Claim in accordance with the terms hereof within 20 Business Days after the receipt of notice thereof, the Indemnitee may elect to defend against the Third Party Claim, and the Indemnifying Party will be liable for all reasonable expenses of such defense to the extent the Indemnifying Party is otherwise obligated hereunder to indemnify Indemnitee with respect to such Third Party Claim.

(d) Direct Losses. Any claim by an Indemnitee on account of an Indemnifiable Loss which does not result from a Third Party Claim (a “Direct Loss”) will be asserted by giving the Indemnifying Party prompt written notice thereof, stating the nature of such Loss in reasonable detail and indicating the estimated amount, if practicable. The Indemnifying Party will have a period of 20 Business Days within which to respond to such claim of a Direct Loss. If the Indemnifying Party rejects such claim, or does not respond within such period, the Indemnitee may seek enforcement of its rights to indemnification under this Agreement. Any failure by the Indemnifying Party to respond under this Section 9.3 (d) will not constitute an admission by the Indemnifying Party with respect to the claim asserted.

(e) If the amount of any Indemnifiable Loss, at any time subsequent to the making of an indemnity payment in respect thereof, is reduced by recovery, settlement, or otherwise under or pursuant to any insurance coverage, or pursuant to any claim, recovery, settlement, or payment by or against any other Person, the amount of such reduction, less any costs, expenses, or premiums incurred in connection therewith, will promptly be repaid by the Indemnitee to the Indemnifying Party. Upon making any indemnity payment, the Indemnifying Party will, to the extent of such indemnity payment, be subrogated to all rights of the Indemnitee against any third party in respect of the Indemnifiable Loss to which the indemnity payment relates; provided, however, that (i) the Indemnifying Party is then in compliance with its obligations under this Agreement in respect of such Indemnifiable Loss and (ii) until the Indemnitee recovers full payment of its Indemnifiable Loss, any and all claims of the Indemnifying Party against any such third party on account of said indemnity payment will be subordinated to the Indemnitee’s rights against such third party. Without limiting the generality or effect of any other provision hereof, the Indemnitee and the Indemnifying Party will duly execute upon request all instruments reasonably necessary to evidence and perfect the above described subrogation and subordination rights, and otherwise cooperate in the prosecution of such claims at the direction of the Indemnifying Party.

(f) A failure to give timely notice as provided in this Section 9.3 will affect the rights or obligations of a Party hereunder only to the extent that, as a result of such failure, the Party entitled to receive such notice was actually prejudiced as a result of such failure. Notwithstanding the foregoing, no claim for indemnification made after expiration of the applicable time periods set forth in this Article IX will be valid.

9.4 Limitations on Indemnification.

(a) A Party may assert a claim for indemnification under Section 9.2(a)(ii) or Section 9.2(b)(ii), as the case may be, only to the extent the Indemnitee gives notice of such claim to the Indemnifying Party prior to the expiration of the applicable time period set forth in Section 9.1. Any claim pursuant to Section 9.2(a)(i) or Section 9.2(b)(i) in respect of a covenant or agreement which by its terms is to be performed prior to or at the Closing must be asserted within one year following the Closing Date. Any claim for indemnification not made in accordance with Section 9.3 by a Party on or prior to the applicable date set forth in Section 9.1 or this Section 9.4 (a), and the other Party’s indemnification obligations with respect thereto, will be irrevocably and unconditionally released and waived.

(b) Notwithstanding any other provision of this Article IX, except as provided in the second sentence of this Section 9.4 (b): (i) Seller will not have any indemnification obligations for Indemnifiable Losses under Sections 9.2(a)(i) and 9.2(a)(ii) (A) for any individual item where the Loss relating thereto is less than $50,000 and (B) in respect of each individual item where the Loss relating thereto is equal to or greater than $50,000, unless the aggregate amount of all such Losses exceeds 1% of the Purchase Price, and then only to the extent of such excess; and (ii) in no event will the aggregate indemnification to be paid by Seller under Sections 9.2(a)(i) and 9.2(a)(ii) exceed 10% of the Purchase Price. Notwithstanding the foregoing, the limitations set forth in Section 9.4(b)(i) and 9.4(b)(ii) will not apply to claims asserted by Buyer arising from the intentional fraud of Seller.

(c) Notwithstanding any other provision of this Article IX, except as provided in the second sentence of this Section 9.4 (c): (i) Buyer will not have any indemnification obligations for Indemnifiable Losses under Sections 9.2(b)(i) and 9.2(b)(ii) (A) for any individual item where the Loss relating thereto is less than $50,000 and (B) in respect of each individual item where the Loss relating thereto is equal to or greater than $50,000, unless the aggregate amount of all such Losses exceeds 1% of the Purchase Price, and then only to the extent of such excess; and (ii) in no event will the aggregate indemnification to be paid by Buyer under Sections 9.2(b)(i) and 9.2(b)(ii) exceed 10% of the Purchase Price. Notwithstanding the foregoing, the limitations set forth in Sections 9.4(c)(i) and 9.4(c)(ii) will not apply to claims asserted by Seller arising from the intentional fraud of Buyer.

(d) Notwithstanding anything to the contrary in this Agreement, Buyer shall not be entitled to indemnification under this Article IX with respect to any breach or inaccuracy of any representation, warranty, covenant or agreement of Seller if (i) Seller provides written notice to Buyer at least five Business Days prior to Closing describing in detail such breach or inaccuracy, (ii) Seller simultaneously and irrevocably informs Buyer that, because of such breach or inaccuracy Buyer is not required to consummate the transactions contemplated by this Agreement by reason of Section 8.2(b) or 8.2(c), as the case may be, and (iii) the Closing occurs.

(e) Notwithstanding anything contained in this Agreement to the contrary, except for the representations and warranties contained in Article V, neither Seller nor any other Person is making any other express or implied representation or warranty, whether arising by operation of law or otherwise, with respect to Seller, the Business, the Purchased Assets, the Assumed Obligations or the transactions contemplated by this Agreement, including, but in no way limited to, any representation or warranty, as to liabilities, operations of the Purchased Assets, condition, merchantability, habitability or fitness for a particular use, marketability, value or quality of the Purchased Assets or the prospects (financial and otherwise), risks and other incidents of the Purchased Assets. Except for the representations and warranties contained in Article V, Seller expressly disclaims, whether made by Seller or its Affiliates, officers, directors, employees, agents, or representatives, any representation or warranty of merchantability, usage, suitability or fitness for any particular purpose with respect to the Purchased Assets, or any part thereof, or as to the workmanship thereof, or the absence of any defects therein, whether latent or patent, or compliance with pipeline safety or environmental requirements, or the applicability of any governmental requirements, including but not limited to any environmental protection, pollution control and land use laws, rules, regulations, orders and requirements, including but not limited to those pertaining to the use, handling, generation, treatment, storage or disposal of any toxic or hazardous waste or toxic, hazardous or regulated substance, or whether Seller possesses sufficient owned real property or personal property to operate the Purchased Assets. Except as otherwise expressly provided in Article V, Seller further specifically disclaims any representation or warranty regarding the absence of hazardous substances or liability or potential liability arising under Environmental Laws with respect to the Purchased Assets.

(f) Any claims Buyer may have for breach of any representation or warranty in this Agreement or any Ancillary Agreement must be based solely on the representations and warranties of Seller set forth in Article V. In furtherance of the foregoing, except for the representations and warranties contained in Article V, Buyer acknowledges and agrees that none of Seller, any of its Affiliates or any other Person will have or be subject to any liability to Buyer or any other Person for, and Seller hereby expressly disclaims all liability and responsibility for, any representation, warranty, projection, forecast, statement, or information made, communicated, or furnished (orally or in writing) to Buyer or any of Buyer’s Representatives, including any confidential memoranda distributed on behalf of Seller relating to the Business, the Purchased Assets, or the Assumed Obligations or other publications or data room information provided to Buyer or Buyer’s Representatives, or any other document or information in any form provided to Buyer or Buyer’s Representatives in connection with the sale of the Purchased Assets, the assumption of the Assumed Obligations, and the transactions contemplated hereby (including any opinion, information, projection, or advice that may have been or may be provided to Buyer or Buyer’s Representatives by any of Seller’s Representatives). BUYER HEREBY ACKNOWLEDGES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES EXPRESSLY SET FORTH IN ARTICLE V, THE BUSINESS AND THE PURCHASED ASSETS ARE BEING PURCHASED ON AN “AS IS, WHERE IS” BASIS, WITH ALL FAULTS AND WITH ALL KNOWN AND UNKNOWN ENVIRONMENTAL CONDITIONS AND LIABILITIES (INCLUDING WITHOUT LIMITATION STRICT LIABILITY).

9.5 Applicability of Article IX. For the avoidance of doubt, Seller and Buyer agree that the remedies and obligations under this Article IX apply only following the Closing, and that prior to the Closing or in the event that this Agreement is terminated the Parties’ remedies will be determined by applicable Law and the provisions of Article X.

9.6 Tax Treatment of Indemnity Payments. Seller and Buyer agree to treat any payment made pursuant to this Article IX as an adjustment to the Purchase Price for federal, state, and local income Tax purposes.

9.7 No Consequential Damages. Notwithstanding anything to the contrary elsewhere in this Agreement or provided for under any applicable Law, except as specifically provided in Sections 10.3(b), 10.3(c) and the proviso to this Section 9.7, none of either Party or Parent will, in any event, be liable to the other Party and Parent, or to the Parties, as the case may be, either in contract or in tort, for any consequential, indirect, special, lost profits or punitive damages, including loss of future revenue, income, or profits, or loss of business reputation or opportunity of the other Party and Parent, or of the other Parties, as the case may be, relating to the breach or alleged breach hereof or otherwise, whether or not the possibility of such damages has been disclosed to the other Party and Parent, or any one of them, or to the Parties, or any one of them, as the case may be, in advance or could have been reasonably foreseen by such other Party and Parent, or any one of them, or such Parties, or any one of them, as the case may be; provided, that the limitations contained in this Section 9.7 shall not apply to any Claim for diminution in value.

9.8 Exclusive Remedy. Seller and Buyer acknowledge and agree that, from and after the Closing, the sole and exclusive monetary remedy for any breach or inaccuracy, or alleged breach or inaccuracy, of any representation or warranty in this Agreement or the Ancillary Agreements (other than the Transition Services Agreement) or any covenant or agreement to be performed hereunder or thereunder will be indemnification in accordance with this Article IX. In furtherance of the foregoing, Seller and Buyer hereby waive, to the fullest extent permitted by applicable Law, any and all other rights, claims, and causes of action (including rights of contributions, if any) that may be based upon, arise out of, or relate to this Agreement or the Ancillary Agreements (other than the Transition Services Agreement), or the negotiation, execution, or performance of this Agreement or the Ancillary Agreements (other than the Transition Services Agreement) (including any tort or breach of contract claim or cause of action based upon, arising out of, or related to any representation or warranty made in or in connection with this Agreement or the Ancillary Agreement (other than the Transition Services Agreement) or as an inducement to enter into this Agreement or the Ancillary Agreements (other than the Transition Services Agreement)), known or unknown, foreseen or unforeseen, which exist or may arise in the future, that it may have against the other arising under or based upon any Law (including any such Law under or relating to environmental matters), common law, or otherwise.

(c) This Agreement may be terminated by Buyer if (i) any Required Regulatory Approval (A) has been denied by the applicable Governmental Entity and all appeals of such denial have been taken and have been unsuccessful, or (B) has become a Final Regulatory Order and such Final Regulatory Order imposes conditions or requirements that would result in the failure of the condition in Section 8.2(e), or (ii) one or more courts of competent jurisdiction in the United States or any State has issued an Order permanently restraining, enjoining, or otherwise prohibiting the Closing, and such Order has become final and nonappealable.

(d) This Agreement may be terminated by Buyer if there has been a breach by Seller as of the date of this Agreement of any representation or warranty or any breach by Seller of any covenant, in each case made by it in this Agreement which has prevented the satisfaction of any condition to the obligations of Buyer to effect the Closing and such breach has not been cured by Seller or waived by Buyer within 20 Business Days after all other conditions to Closing have been satisfied or are capable of being satisfied.

(e) This Agreement may be terminated by Seller if there has been a breach by Buyer as of the date of this Agreement of any representation or warranty or any breach by Buyer of any covenant, in each case made by it in this Agreement which has prevented the satisfaction of any condition to the obligations of Seller to effect the Closing and such breach has not been cured by Buyer or waived by Seller within 20 Business Days after all other conditions to Closing have been satisfied or are capable of being satisfied.

(f) This Agreement may be terminated by Seller if (i) any Required Regulatory Approval (A) has been denied by the applicable Governmental Entity and all appeals of such denial have been taken and have been unsuccessful, or (B) has become a Final Regulatory Order and such Final Regulatory Order imposes conditions or requirements that would result in the failure of the condition in Section 8.3(d) or (ii) one or more courts of competent jurisdiction in the United States or any State has issued an Order permanently restraining, enjoining, or otherwise prohibiting the Closing, and such Order has become final and nonappealable.

(g) This Agreement will terminate if (i) (A) the lenders under the Debt Commitment Letter assert the failure of a condition precedent to the funding of their commitments thereunder, assert that they would not be required to or would not, fund their commitments thereunder were the Closing to occur at that time, purport to terminate their commitments thereunder or assert that their commitments have been terminated or (B) the Debt Commitment Letter is otherwise terminated (collectively, a “Potential Financing Failure”) and (ii) Buyer fails to obtain a renewal of, or comparable substitute for, the Debt Commitment Letter or otherwise resolve such Potential Funding Failure within 30 days following such assertion, purported termination or termination.

(h) This Agreement may be terminated by Seller if any Required Regulatory Approval has become an Order and Buyer asserts that the Order, if it becomes a Final Regulatory Order, will not meet the closing condition in Section 8.2(e)(ii) and Buyer does not agree to waive such closing condition within 30 days of receipt of such Order.

(i) This Agreement may be terminated by Buyer if any Required Regulatory Approval has become an Order and Seller asserts that the Order, if it becomes a Final Regulatory Order, will not meet the closing condition in Section 8.3(d)(ii) and Seller does not agree to waive such closing condition within 30 days of receipt of such Order.

10.2 Procedure and Effect of Termination. In the event of termination of this Agreement by either or both of the Parties pursuant to Section 10.1, subject to any cure periods contemplated therein, written notice thereof will forthwith be given by the terminating Party to the other Party and this Agreement will terminate and the transactions contemplated hereby will be abandoned, without further action by either Party, whereupon the liabilities of the Parties and Parent hereunder will terminate, except as provided in Section 10.3. If prior to Closing either Party resorts to legal proceedings to enforce this Agreement, the prevailing Party in such proceedings shall be entitled to recover all costs incurred by such Party, including reasonable attorney’s fees, in addition to any other relief to which such Party may be entitled; provided, however, and notwithstanding anything to the contrary in this Agreement, in no event shall either Party be entitled under this Section 10.2 to receive any punitive, indirect or consequential damages.

10.3 Remedies upon Termination. If this Agreement is terminated as provided herein:

(a) The obligations of the Parties under Article I, Article X and Article XII, and Sections 7.2(b), 7.2(c), 7.2(d), 7.3, 7.5 and 11.1 will survive the termination of this Agreement pursuant to Section 10.1.

(b) Buyer will pay to Seller a fee equal to $25,000,000 if Seller terminates this Agreement pursuant to Section 10.1(e).

(d) In view of the difficulty of determining the amount of damages which may result to the non-terminating Party from a termination pursuant to any of the Sections of this Agreement referenced in Section 10.3(b) or 10.3(c), and the failure of the terminating Party to consummate the transactions contemplated by this Agreement or which may result to Seller from a termination pursuant to Section 10.1(g), Buyer and Seller have mutually agreed that each of the payments set forth in Sections 10.3(b) and 10.3(c) shall be made to the non-terminating Party, or the payment set forth in Section 10.3(f) shall be made to Seller, as liquidated damages, and not as a penalty, and this Agreement shall thereafter terminate except for those provisions which by their terms survive termination of this Agreement. In the event of any termination of this Agreement, the Parties have agreed that each of the payments set forth in Sections 10.3(b), 10.3(c), 10.3(e) and 10.3(f) shall be the sole and exclusive remedy of each Party and Parent against the other Party and Parent and their respective

Affiliates. ACCORDINGLY, THE PARTIES HEREBY ACKNOWLEDGE THAT (1) THE EXTENT OF DAMAGES TO THE NON-TERMINATING PARTY CAUSED BY THE FAILURE OF THIS TRANSACTION TO BE CONSUMMATED WOULD BE IMPOSSIBLE OR EXTREMELY DIFFICULT TO ASCERTAIN, (2) THE AMOUNT OF THE LIQUIDATED DAMAGES PROVIDED FOR IN EACH OF SECTIONS 10.3(b), 10.3(c) AND 10.3(f) ARE FAIR AND REASONABLE ESTIMATES OF SUCH DAMAGES UNDER THE CIRCUMSTANCES AND (3) RECEIPT OF SUCH LIQUIDATED DAMAGES BY THE NON-TERMINATING PARTY DOES NOT CONSTITUTE A PENALTY. THE PARTIES HEREBY FOREVER WAIVE AND AGREE TO FOREGO TO THE FULLEST EXTENT UNDER APPLICABLE LAW ANY AND ALL RIGHTS THEY HAVE OR IN THE FUTURE MAY HAVE TO BRING ANY ACTION OR PROCEEDING DISPUTING OR OTHERWISE OBJECTING TO ANY OR ALL OF THE FOREGOING PROVISIONS OF THIS SECTION 10.3.

(e) (i) Buyer will pay to Seller a fee equal to $25,000,000 if (A) this Agreement is terminated pursuant to Section 10.1(b), 10.1(c) or 10.1(h) primarily as a result of the failure to satisfy the condition set forth in Section 8.2(e)(ii) or (B) this Agreement is terminated pursuant to Section 10.1(b), 10.1(c) or 10.1(h), primarily as a result of the failure to satisfy the conditions set forth in Section 8.2(a), 8.2(c) or 8.2(d) arising out of Buyer's assertion that a Material Adverse Effect has occurred as a result of a change in Law issued by, administered by or relating to the authority or responsibilities of the NMPRC and (ii) Seller will pay to Buyer a fee equal to $25,000,000 if this Agreement is terminated pursuant to Section 10.1(b), 10.1(f) or 10.1(i) primarily as a result of the failure to satisfy the condition set forth in Section 8.3(d)(ii). Neither Buyer nor Seller shall be obligated to pay any fee set forth in this Section 10.3(e) if the failure to satisfy the condition set forth in Section 8.2(e)(ii) or 8.3(d)(ii), as the case may be, primarily results from the failure to obtain, renew or secure any Franchise as may be deemed necessary by the Parties in connection with the transactions contemplated hereby. Under no circumstances shall any Party be entitled to receive a payment pursuant to this Section 10.3(e) and a payment pursuant to Section 10.3(b), 10.3(c) or 10.3(f), as the case may be.

(f) Buyer will pay to Seller a fee equal to $25,000,000 if this Agreement is terminated pursuant to Section 10.1(g) unless, at the time of such termination, the conditions set forth in Sections 8.2(a) and 8.2(c) shall not be satisfied (determined as if the time of termination were the Effective Time). Under no circumstances shall Seller be entitled to receive a payment pursuant to this Section 10.3(f) and a payment pursuant to Section10.3(b) or 10.3(e).

(g) All payments under this Section 10.3 shall be from payor to payee by wire transfer of immediately available funds to a bank account in the United States of America designated in writing by payee not later than three (3) Business Days following payor’s receipt of such account designation from payee.

(h) No amount shall be due by Buyer or Seller under Section 10.3(b) or 10.3(c) if this Agreement is terminated prior to the Closing and the Closing does not occur primarily because a representation and warranty of a Party or Parent that was true and correct on the date of this Agreement became not true and correct thereafter not as a result of a breach of covenant by such Party or Parent.

ARTICLE XI

PARENT GUARANTEE

11.1 Guarantee. (a) Parent hereby absolutely, unconditionally and irrevocably guarantees to Seller, as primary obligor and not merely as a surety, (i) the due and punctual payment of all monetary obligations of Buyer under this Agreement and the Ancillary Agreements and (ii) the full and complete performance of all covenants and agreements of Buyer under this Agreement and the Ancillary Agreements (the obligations of Buyer specified in clauses (i) and (ii) above, collectively, the “Guaranteed Obligations”).

(b) The guarantee contained in this Article XI shall remain in full force and effect until all of the Guaranteed Obligations shall have been satisfied by payment in full.

11.2 Nature of Guarantee. Parent guarantees that the Guaranteed Obligations will be duly and punctually paid and performed in accordance with the terms of this Article XI. If for any reason Buyer shall fail or be unable to duly and punctually pay or perform, or cause to be duly and punctually paid or performed, the Guaranteed Obligations as and when the same shall become due and payable, Parent shall, subject to the terms and conditions of this Article XI, forthwith duly and punctually pay or perform, or cause to be duly and punctually paid or performed, such Guaranteed Obligations. Parent further agrees that the guarantee contained in this Article XI (the “Parent Guarantee”) constitutes a guarantee of payment and performance when due and not of collection and is in no way conditioned or contingent upon any attempt to collect from Buyer.

11.3 Representations and Warranties of Parent. Solely for the purpose of this Article XI, Parent represents and warrants to Seller as follows:

(a) Organization. Parent is a limited liability company duly organized, validly existing, and in good standing under the laws of the state of Delaware and has all requisite corporate power and authority to own, lease, and operate its properties and to carry on its business as is now being conducted.

(b) Authority Relative to this Agreement and the Parent Guarantee. Parent has all corporate power and authority necessary to execute and deliver this Agreement and to perform its obligations in connection with the Parent Guarantee. The execution and delivery of this Agreement and the performance of the obligations under the Parent Guarantee have been duly and validly authorized by the managing members of Parent and no other proceedings on the part of Parent are necessary to authorize this Agreement or the performance of Parent’s obligations under the Parent Guarantee. This Agreement has been duly and validly executed and delivered by Parent, and constitutes a valid and binding agreement of Parent, enforceable against Parent in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, or other similar laws affecting or relating to enforcement of creditors’ rights generally or general principles of equity.

(c) Consents and Approvals; No Violation. Except as set forth in Schedule 11.3(c), the execution and delivery of this Agreement and the performance by Parent of its obligations under the Parent Guarantee, do not:

(i) conflict with or result in any breach of the Governing Documents of Parent;

(ii) result in a default (including with notice, lapse of time, or both), or give rise to any right of termination, cancellation, or acceleration, under any of the terms, conditions, or provisions of any note, bond, mortgage, indenture, agreement, lease, or other instrument or obligation to which Parent is a party or by which Parent or any of its assets may be bound, except for such defaults (or rights of termination, cancellation, or acceleration) as to which requisite waivers or consents have been, or will prior to the Effective Time be, obtained or which if not obtained or made would not, individually or in the aggregate, prevent or materially delay the consummation of the transactions contemplated by this Agreement or the performance by Parent of its obligations under the Parent Guarantee;

(iii) violate any Law or Order applicable to Parent or any of its assets; or

(iv) require any declaration, filing, or registration with, or notice to, or authorization, consent, or approval of any Governmental Entity, other than such declarations, filings, registrations, notices, authorizations, consents, or approvals which, if not obtained or made, would not, individually or in the aggregate, prevent or materially delay the consummation of the transactions contemplated by this Agreement or the performance by Parent of its obligations under the Parent Guarantee.

11.4 Sole Obligation of Parent. This Article XI contains the only provisions in this Agreement that are applicable to Parent. Parent shall not have any obligations under this Agreement other than those expressly set forth in this Article XI.

ARTICLE XII

MISCELLANEOUS PROVISIONS

12.1 Amendment and Modification. Except as provided in Section 7.8, this Agreement and any Ancillary Agreement may be amended, modified, or supplemented only by written agreement of Seller, Buyer and Parent.

12.2 Waiver of Compliance; Consents. Except as otherwise provided in this Agreement, any failure of either Party or Parent to comply with any obligation, covenant, agreement, or condition herein may be waived by the Party or Parent, as the case may be, entitled to the benefits thereof only by a written instrument signed by the Party or Parent, as the case may be, granting such waiver, but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement, or condition will not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

12.3 Notices. All notices and other communications hereunder will be in writing and will be deemed given if delivered personally or by facsimile transmission, or mailed by overnight courier or certified mail (return receipt requested), postage prepaid, to the Party or Parent, as the case may be, being notified at such Party’s or Parent’s address indicated below (or at such other address for a Party or Parent as is specified by like notice; provided, that notices of a change of address will be effective only upon receipt thereof):

12.4 Assignment. This Agreement and any Ancillary Agreement and all of the provisions hereof and thereof will be binding upon and inure to the benefit of the Parties and Parent and their respective successors and permitted assigns, but neither this Agreement nor any Ancillary Agreement nor any of the rights, interests, or obligations hereunder or thereunder may be assigned by either Party or Parent, without the prior written consent of the other Party and Parent, or the Parties, as the case may be, nor is this Agreement or any Ancillary Agreement intended to confer upon any other Person except the Parties and Parent any rights or remedies hereunder. Notwithstanding the foregoing, Buyer may assign any or all of its rights and obligations hereunder to a Buyer Designee, or as security in connection with the Financing or any other financing transaction. Upon receipt of notice by Seller from Buyer of any such assignment to a Buyer Designee, such assignee will be deemed to have assumed, ratified, agreed to be bound by and perform all such obligations, and all references herein to “Buyer” shall thereafter be deemed to be references to such assignee, in each case without the necessity for further act or evidence by the Parties hereto or Parent or such assignee; provided, however, that no such assignment shall relieve or discharge Buyer from any of its obligations hereunder or under any of the Ancillary Agreements. No provision of this Agreement creates any third party beneficiary rights in any employee or former employee of Seller (including any beneficiary or dependent thereof) in respect of continued employment or resumed employment, and no provision of this Agreement creates any rights in any such Persons in respect of any benefits that may be provided, directly or indirectly, under any employee benefit plan or arrangement.

12.5 Governing Law. This Agreement and any Ancillary Agreement are governed by and construed in accordance with the laws of the State of New Mexico (regardless of the laws that might otherwise govern under applicable principles of conflicts of law) as to all matters, including but not limited to matters of validity, construction, effect, performance and remedies. EACH OF THE PARTIES AND PARENT AGREES THAT VENUE IN ANY AND ALL ACTIONS AND PROCEEDINGS RELATED TO THE SUBJECT MATTER OF THIS AGREEMENT AND ANY ANCILLARY AGREEMENT (OTHER THAN THE TRANSITION SERVICES AGREEMENT) SHALL BE IN THE STATE AND FEDERAL COURTS IN AND FOR ALBUQUERQUE, NEW MEXICO WHICH COURTS SHALL HAVE EXCLUSIVE JURISDICTION FOR SUCH PURPOSE, AND THE PARTIES AND PARENT IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS AND IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF ANY SUCH ACTION OR PROCEEDING. SERVICE OF PROCESS MAY BE MADE IN ANY MANNER RECOGNIZED BY SUCH COURTS.

12.6 Severability. Any term or provision of this Agreement or any Ancillary Agreement that is invalid or unenforceable in any situation in any jurisdiction will not affect the validity or enforceability of the remaining terms and provisions hereof or thereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

12.7 Entire Agreement. This Agreement will be a valid and binding agreement of the Parties and Parent only if and when it is fully executed and delivered by the Parties and Parent, and until such execution and delivery no legal obligation will be created by virtue hereof. This Agreement and the Ancillary Agreements, together with the Schedules and Exhibits hereto and thereto and the certificates and instruments delivered under or in accordance herewith or therewith, embody the entire agreement and understanding of the Parties and Parent in respect of the transactions contemplated by this Agreement. This Agreement supersedes all prior agreements and understandings between the Parties and Parent with respect to such transactions. All conflicts or inconsistencies, if any, between the terms hereof and the terms of any of the Ancillary Agreements shall be resolved in favor of this Agreement (except in the case of any Special Warranty Deed, in which event such Special Warranty Deed shall govern and control with respect to the matters addressed therein).

12.8 Bulk Sales or Transfer Laws. Buyer acknowledges that Seller will not comply with the provision of any bulk sales or transfer laws of any jurisdiction in connection with the transactions contemplated by this Agreement. Buyer hereby waives compliance by Seller with the provisions of the bulk sales or transfer laws of all applicable jurisdictions.

12.9 Delivery. This Agreement, and any certificates and instruments delivered under or in accordance herewith, may be executed in multiple counterparts (each of which will be deemed an original, but all of which together will constitute one and the same instrument), and may be delivered by facsimile transmission, with originals to follow by overnight courier or certified mail (return receipt requested).

12.10 Waiver of Jury Trial. EACH OF THE PARTIES AND PARENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ANCILLARY AGREEMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

IN WITNESS WHEREOF, the Parties and Parent have caused this agreement to be signed by their respective duly authorized officers as of the date first above written.
