The principal business address and the principal office address of Westar are located at 818 South Kansas Avenue, Topeka, Kansas 66612. The Company is engaged in the production, purchase, transmission, distribution and sale of electricity, and, through its subsidiaries and investments, the delivery and sale of energy-related products and the provision of monitored security services. The principal business address and the principal office address of Western are located at 818 South Kansas Avenue, Topeka, Kansas 66612. Each director and each executive officer of each of the Reporting Persons is, to the knowledge of the Reporting Persons, a citizen of the United States of America.

During the last five years none of the Reporting Persons or, to the knowledge of the Reporting Persons, any of their directors or executive officers has been convicted of a criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which any of the Reporting Persons or any of such directors or officers was or is subject to a judgment, decree or final order enjoining future violations of or prohibiting or mandating activities subject to, federal or state securities laws, or finding any violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration

The shares of common stock acquired by Westar are original issue shares of the Company and the transfer of these shares is restricted under applicable securities laws. Item 4. Purpose of Transaction. On November 8, 2000, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Public Service Company of New Mexico ("PNM") and certain of PNM's subsidiaries pursuant to which PNM (or a holding company formed by PNM) will acquire the Company in a tax-free stock-for-stock merger (the "Merger") and a portion of each outstanding share of Company common stock will be converted into common stock of PNM or the holding company formed by PNM, and the remainder will be exchanged for common stock of Westar held by the Company. The Company and Westar entered into the Asset Allocation Agreement at the same time as the Merger Agreement. Among other things, the Asset Allocation Agreement permits a receivable owed by the Company to Westar to be converted into certain securities of the Company. At the closing of the merger, any of these securities then owned by Westar will be converted into securities of PNM or the holding company formed by PNM. Westar will continually review its ownership in the Company and may decide to make additional purchases of common stock or other securities of the Company in the future by converting the remaining balance of the receivable pursuant to the terms of the Asset Allocation Agreement or by making purchases in the open market, subject to its evaluation of the Company's business, prospects and financial condition, the market for the common stock of the Company, other opportunities available to Westar, general economic conditions, money and stock market conditions and other future developments. At any time, Westar may change its intention with respect to the acquisition and/or retention of the shares of common stock of the Company, and may increase, decrease or entirely dispose of its holdings of common stock of the Company, although Westar currently has no intention to do so. Westar does not currently have any specific plans or proposals with respect to the matters set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D, but may take actions related to any such matters in the future.

Upon the determination by the Split-Off Agent of such number of fractional shares, as soon as practicable after the Split-Off Date, the Split-Off Agent, acting on behalf of the holders thereof, shall sell such fractional shares for cash on the open market in each case at the then prevailing market prices and shall disburse to each holder entitled thereto, in lieu of any fractional share, without interest, that holder's ratable share of the proceeds of that sale, after making appropriate deductions of the amount required, if any, to be withheld for United States federal income Tax purposes. ARTICLE V INDEMNIFICATION AND OTHER MATTERS Section 5.01. Westar Indemnification of Western Group. (a) Subject to Section 5.03, from and after the Split-Off Date, Westar shall indemnify, defend and hold harmless each member of the Western Group, their Affiliates (including, for the avoidance of doubt, Parent) and their respective officers, directors and employees (each, a "Western Indemnitee") from and against any and all Damages incurred or suffered by any Western Indemnitee arising out of (i) any and all Westar Group Liabilities other than those relating to Taxes, (ii) the breach by any member of the Westar Group of any obligation under this Agreement, and (iii) any Western Officer Loan Liability. Notwithstanding anything to the contrary contained in this Agreement, all indemnities relating to Taxes or a breach of any obligation under the Tax Disaffiliation Agreement shall be governed solely by the specific terms of the Tax Disaffiliation Agreement. (b) Subject to Section 5.03, from and after the Split-Off Date, Westar shall indemnify, defend and hold harmless each Western Indemnitee and each Person, if any, who controls any Western Indemnitee within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all Damages caused by any untrue statement or alleged untrue statement of a material fact contained in the Split-Off S-4 or Rights Offering S-1 or any amendment thereof or the Information Statement, Proxy Statement or Prospectus (in each case as amended or supplemented if Westar shall have furnished any amendments or supplements thereto), or caused by any omission or

alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except to the extent such Damages were caused by information provided by any member of the Western Group specifically for inclusion therein. (c) Westar shall indemnify Western and Parent to the extent the Net Present Value (as defined below) of (x) any Gross-Up Payments, (y) any other incremental payments and benefits, net of any tax benefits to Western, Parent or any of their Affiliates, made, or to be made, by Western under the Employment Agreements to a covered employee (provided, however, that such incremental payments or benefits result from both a termination of employment and a change in control (as defined therein) occurring by reason of transactions contemplated by the Merger Agreement (excluding any payments attributable to stock options, restricted stock, restricted share units and other equity-based compensation)), and (z) any incremental payments or benefits, net of any tax benefits to Western, Parent or any of their Affiliates, that Western employees become entitled to receive under the Western Executive Salary Continuation Plan solely as a result of a change in control (as defined therein), exceeds (i) if there are Gross-Up Payments (or additional Tax is due by Western attributable to the loss of deduction under Section 280G of the Code for such payments), $80,000,000, and (ii) if there are no Gross-Up Payments (and no additional Tax is due by Western attributable to the loss of deduction under Section 280G of the Code for such payments), $55,000,000. For purposes of clarification, payments or benefits which were vested prior to the date of the change in control (as defined in the applicable agreement or plan) or which are earned after such date shall not be considered for purposes of this indemnification. For purposes of this provision, Net Present Value determined under subsection (z) above, shall be the amount necessary to purchase single premium annuities from an insurance company with an A.M. Best rating of A+ or better to provide the incremental benefits described in said subsection (z), and under subsections (x) and (y) above shall be (I) for any single-sum payment or benefit made within 90 days after the Effective Date, the actual amount of the payment or benefit, and (II) for any other payment or benefit, the amount determined using a discount rate of 120% of the applicable federal rate and other reasonable assumptions. Such Net Present Value shall initially be calculated (the "Employee Payments Calculation") by Western prior to, but as of, the Effective Time assuming (i) there will be no Gross-Up Payments (unless prior to the Effective Date Western, Westar and PNM mutually agree otherwise), and (ii) Western will receive a full tax benefit based on Western's top effective tax rates for Western's tax year in which the Effective Date occurs. The Employee Payments Calculation shall be delivered to Parent on or prior to the Cut-Off Date (as defined in the Merger Agreement) and shall have sufficient detail to enable Parent to ascertain whether or not such calculation was made in conformity with the provisions of this Agreement. The notice and dispute provisions of Section 3.2(b)(ii) of the Merger Agreement applicable to the Adjustment Calculation (as defined therein) shall also apply to the Employee Payments Calculation. If such Gross-Up Payments assumption is Finally Determined to not have been correct, the indemnification provided above shall be recalculated based on the corrected assumptions. If as a result of such recalculation, Westar's indemnification obligation under this Section 5.03(c) exceeds any prior amounts paid by Westar pursuant to this Section 5.03(c), Westar shall pay to Western such excess amount together with interest thereon at the rate of 120% of the applicable federal rate (in effect on the Effective Date) for the period beginning on the Effective Date and ending on the date such payment is made. The payment, if any, under the prior sentence shall be made within 30 days of the date Finally Determined. (d) Each of Western and Westar shall, and shall cause the other members of their respective Groups and their respective Affiliates to, use reasonable efforts in good faith (not extending, however, to any obligation to continue to employ any person or to continue any employment benefit or compensation beyond what the parties are otherwise obligated to do pursuant to this Agreement, the other Split-Off Documents or the Merger Agreement) to avoid the imposition of any Gross-Up Payments. Section 5.02. Western Indemnification of Westar Group.

(a) Subject to Section 5.03, from and after the Split-Off Date, Western shall indemnify, defend and hold harmless each member of the Westar Group, their Affiliates and their respective officers, directors and employees (each, a "Westar Indemnitee") from and against any and all Damages incurred or suffered by any Westar Indemnitee arising out of (i) any and all Western Group Liabilities other than those relating to Taxes and (ii) the breach by any member of the Western Group of any obligation under this Agreement. Notwithstanding anything to the contrary contained in this Agreement, all indemnities relating to Taxes or a breach of any obligation under the Tax Disaffiliation Agreement shall be governed solely by the specific terms of the Tax Disaffiliation Agreement). (b) Subject to Section 5.03, from and after the Split-Off Date, Western shall indemnify, defend and hold harmless each Westar Indemnitee and each Person, if any, who controls any Westar Indemnitee within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all Damages caused by any untrue statement or alleged untrue statement of a material fact contained in the Rights Offering S-1, the Split-Off S-4 or any amendment thereof or the Information Statement, Proxy Statement or Prospectus (in each case as amended or supplemented if Westar shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that those Damages are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information that is furnished to Westar by Western or any of its Affiliates (other than any member of the Westar Group) specifically for use therein. (c) Except as provided in Section 5.01(c), Western shall indemnify each member of the Westar Group for any and all Liabilities related to (i) any Gross-Up Payments, (ii) any other payments made under the Employment Agreements and (iii) any payments or benefits under the Western Executive Salary Continuation Plan, including, without limitation any shareholder or other third party Claims. Section 5.03. Insurance and Third Party Obligations; Limitation on Liability. (a) Upon indemnification of an Indemnified Party (as defined below), the Indemnifying Party shall be subrogated to the rights of the Indemnified Party against the insurer, to the extent permitted by any applicable Policy, or other third party (other than a third party which is a member of the same Group of which the Indemnified Party is a member) with respect to such indemnified amount. It is expressly agreed that no insurer or any other third party shall be (i) entitled to a benefit it would not be entitled to receive in the absence of the foregoing indemnification provisions, (ii) relieved of the responsibility to pay any insured claims or any other claims to which it is obligated or (iii) entitled to any subrogation rights with respect to any obligation hereunder. (b) Each party shall use all commercially reasonable efforts to mitigate its Damages and not to cause or worsen any Liability which would be a Liability of the other party. If an Indemnified Party shall receive any amount of insurance proceeds or any other amount from a third party in connection with a specific Liability giving rise to indemnification hereunder (i) at any time subsequent to the actual receipt of a payment in full indemnification of such Liability hereunder, then such Indemnified Party shall reimburse the Indemnifying Party for any such indemnification payment made up to the amount of such insurance proceeds or other amounts actually received or (ii) at any time prior to the receipt of any indemnification payment in respect of such Liability hereunder, then the indemnification to be paid under Section 5.01 or 5.02 shall be paid net of the amount of any such insurance proceeds or other amounts actually received. Notwithstanding this Section 5.03, (x) in no event shall any Indemnified Party be required (i) to take any action, or forebear from exercising any right, under the Merger Agreement or any Split-Off Document or (ii) to take any action with respect to, make any demand under or claim any coverage in connection with, any Policy, and (y) nothing herein shall permit any

Indemnifying Party to delay or refrain from making any payment to any Indemnified Party because of the availability or alleged availability of any Policy or insurance proceeds (provided that the foregoing shall not limit the subrogation rights of an Indemnifying Party under Section 5.03(a)). Section 5.04. Notice and Payment of Claims. If any Western Indemnitee or Westar Indemnitee (the "Indemnified Party") determines that it is or may be entitled to indemnification by any party (the "Indemnifying Party") under this Article V (other than in connection with any Action subject to Section 5.05), the Indemnified Party shall deliver to the Indemnifying Party a written notice specifying, to the extent reasonably practicable, the basis for its claim for indemnification and the amount for which the Indemnified Party reasonably believes it is entitled to be indemnified. Within 30 calendar days after receipt of such notice, the Indemnifying Party shall pay the Indemnified Party such amount in cash or other immediately available funds unless the Indemnifying Party objects in writing to the claim for indemnification or the amount thereof. Section 5.05. Notice and Defense of Third-Party Claims. (a) Promptly (and in any event within 10 Business Days) following the earlier of (i) receipt of notice, whether by service of process or otherwise, of the commencement by a third party of any Action against or otherwise involving any Indemnified Party or (ii) receipt of information from a third party alleging the existence of a claim against an Indemnified Party, in either case, with respect to which indemnification may be sought pursuant to this Agreement (a "Third-Party Claim"), the Indemnified Party shall give the Indemnifying Party written notice thereof. The failure of the Indemnified Party to give notice as provided in this Section 5.05 shall not relieve the Indemnifying Party of its obligations under this Agreement, except to the extent that the Indemnifying Party is actually and materially prejudiced by such failure to give notice. (b) Within 30 calendar days after receipt of notice from the Indemnified Party pursuant to Section 5.05(a), the Indemnifying Party may (by giving written notice thereof to the Indemnified Party) elect at its option to, and shall at the request of the Indemnified Party, assume the defense of any Third-Party Claim seeking monetary Damages at the Indemnifying Party's sole cost and expense unless the Indemnifying Party objects in writing to such indemnification claim (in which case the Indemnified Party may not require the Indemnifying Party to assume the defense and the Indemnifying Party shall only assume the defense with the consent of the Indemnified Party). During such 30-calendar day period, unless and until the Indemnifying Party assumes the defense of such a Third-Party Claim or objects in writing, the Indemnified Party shall take such action as it deems appropriate, acting in good faith, and at Indemnifying Party's expense in connection with such Third-Party Claim; provided, however, that the Indemnified Party shall not settle or compromise, or make any offer to settle or compromise, such Third-Party Claim without the prior written consent of the Indemnifying Party (which shall not be unreasonably withheld); and provided further, that in the event that a Third Party Claim seeks injunctive or other non-monetary relief, the Indemnified Party shall be entitled to control the defense of the Third Party Claim at the cost and expense of the Indemnifying Party. (c) If the Indemnifying Party assumes the defense of a Third-Party Claim, (w) it shall keep the Indemnified Party timely informed of all significant developments in connection therewith, (x) the defense shall be conducted by counsel retained by the Indemnifying Party (which counsel shall be reasonably satisfactory to the Indemnified Party), provided that the Indemnified Party shall have the right to participate in such proceedings and to be represented by counsel of its own choosing, and if such Third Party Claim only seeks monetary Damages, such participation shall be at the Indemnified Party's sole cost and expense; and (y) the Indemnifying Party may settle or compromise the Third-Party Claim without the prior written consent of the Indemnified Party so long as such settlement or compromise includes an unconditional release of the Indemnified Party from all claims that are the subject of such Third-Party Claim, provided that the Indemnifying Party may not agree to any such settlement or compromise pursuant to which there is any finding or admission of any violation of Law or pursuant to which any remedy or relief (including but not limited to the

imposition of a consent order, injunction or decree which would restrict the future activity or conduct of the Indemnified Party or any Subsidiary or Affiliate thereof), other than monetary damages for which the Indemnifying Party shall be responsible hereunder, shall be applied to or against the Indemnified Party, without the prior written consent of the Indemnified Party (which shall not be unreasonably withheld). (d) If the Indemnifying Party has not objected in writing to such indemnification claim, and, if at the end of the 30-calendar day period referred to in Section 5.05(b) the Indemnifying Party has not assumed the defense of such claim, or, if earlier, beginning at such time as the Indemnifying Party has declined in writing to assume the defense of a Third-Party Claim, (x) the Indemnified Party will take such steps as it deems appropriate to defend that Third-Party Claim and the defense shall be conducted by counsel retained by the Indemnified Party, provided that the Indemnifying Party shall have the right to participate in such proceedings and to be represented by counsel of its own choosing at the Indemnifying Party's sole cost and expense; and (y) the Indemnifying Party shall reimburse the Indemnified Party on a current basis (and in any event within 30-calendar days after the submission of invoices and bills by an Indemnified Party) for its expenses of investigation, attorneys' and expert witnesses' fees and other out-of-pocket expenses incurred in defending against such Third-Party Claim and the Indemnifying Party shall be bound by the result obtained with respect thereto by the Indemnified Party; provided, further, that the Indemnified Party shall not settle or compromise, or make any offer to settle or compromise, the Third-Party Claim without the prior written consent of the Indemnifying Party (which shall not be unreasonably withheld). (e) The Indemnifying Party shall pay to (or at the direction of) the Indemnified Party in cash the amount, if any, for which the Indemnified Party is entitled to be indemnified hereunder within 15 calendar days after such Third Party Claim has been Finally Determined, in the case of an indemnity claim as to which the Indemnifying Party has acknowledged liability or, in the case of any indemnity claim as to which the Indemnifying Party has not acknowledged liability, within 15 calendar days after such Indemnifying Party's liability, if any, hereunder has been Finally Determined. (f) Notwithstanding any other provision of this Agreement, Western acknowledges and agrees that following the Split-Off Time, Westar shall (solely at its own cost and expense) assume and continue the defense of all the Westar Litigation and that, as long as such settlement or compromise includes an unconditional release of all Western Indemnitees, Westar shall be permitted to settle or compromise such Actions without the consent of Western or any of its Affiliates, provided that Westar may not agree to any such settlement or compromise pursuant to which there is any finding or admission of any violation of Law or pursuant to which any remedy or relief (including but not limited to the imposition of a consent order, injunction or decree which would restrict the future activity or conduct of the Western Indemnitees), other than monetary damages for which the Westar Group shall be responsible hereunder, shall be applied to or against any such Western Indemnitee, without the prior written consent of such Western Indemnitee (which shall not be unreasonably withheld); provided, further, that Westar shall use all commercially reasonable efforts to defend any Western Indemnitee and to cause any Western Indemnitee to be dismissed with prejudice as a party to any pending or future Westar Litigation and, to the extent any Western Indemnitee believes, in its reasonable judgment, that Westar has failed to diligently pursue such defense or dismissal, the Western Indemnitee shall be entitled (at its own cost and expense) to independently move for or otherwise pursue such defense or dismissal and to take such related actions as it may deem necessary or appropriate in connection therewith. Notwithstanding the foregoing, the parties may agree to allocate costs and expenses in any other manner pursuant to a settlement to which Western consents. Westar shall keep Western timely informed of all significant developments with respect to the Westar Litigation to which any Western Indemnitee is a party. (g) Subject to Article VII, each party shall cooperate, and cause their respective Representatives to cooperate, in the defense or prosecution of any Third-Party Claim and shall furnish or cause to be furnished such records,

information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith. Section 5.06. Exclusivity of Remedies. The remedies provided for in this Article V shall be the sole remedy for Damages incurred by an Indemnified Party under this Agreement; provided, if the indemnification provided for in this Article V is unavailable to any Indemnified Party (x) on the grounds that such Indemnified Party was a former Affiliate of the Indemnifying Party or (y) on other public policy grounds, then the Indemnifying Party shall pay to the Indemnified Party's parent such amount that represents the diminution in value to such parent as a result of the Indemnifying Party's inability to so indemnify such Indemnified Party (provided that such amount shall not exceed the amount that would otherwise have been payable by the Indemnifying Party to such Indemnified Party in respect of such claim pursuant to this Article V). ARTICLE VI EMPLOYEE MATTERS AND TRANSITION SERVICES Section 6.01. Employee Matters Generally. Prior to the Split-Off Date, the employees of Westar shall be eligible to participate in all applicable employee benefit plans on the same terms as provided by Western to its employees. Section 6.02. Shared Services Matters Generally. With respect to the provision of certain services by either Group to the other Group after the Separation Time, the parties hereto agree as set forth herein and in the Shared Services Agreement. ARTICLE VII ACCESS TO INFORMATION Section 7.01. Provision of Corporate Records. Except as otherwise specifically set forth in this Agreement or any Ancillary Agreement, immediately prior to or as soon as practicable following the Split-Off Date, each Group shall provide to the other Group all documents, Contracts, books, records and data (including but not limited to minute books, stock registers, stock certificates and documents of title) in its possession relating primarily to the other Group or its business, assets and affairs (after giving effect to the transactions contemplated hereby); provided that if any such documents, Contracts, books, records or data relate to both Groups or the business and operations of both Groups, each such Group shall provide to the other Group true and complete copies of such documents, Contracts, books, records or data. Data stored in electronic form shall be provided in the format in which it existed at the Split-Off Date, except as otherwise specifically set forth in this Agreement or any Ancillary Agreement. Section 7.02. Access to Information. From and after the Split-Off Date and for a reasonable period of time after the Split-Off Date, each Group shall, afford promptly to the other Group and its accountants, counsel and other designated Representatives reasonable access during normal business hours to all documents, Contracts, books, records, computer data and other data in such Group's possession relating to such other Group or the business and affairs of such other Group (after giving effect to the transactions contemplated hereby) (other than data and information subject to (i) an attorney/client or other privilege that is not specifically subject to the provisions of this Article VII or (ii) in the case of access provisions in any joint defense arrangements between a member or members of one Group and a member or members of the other Group, the terms of the relevant joint defense agreement), insofar as such access is reasonably required by such other Group, including, without limitation, for audit, accounting, litigation, regulatory compliance and disclosure and reporting purposes. Section 7.03. Litigation Cooperation. From and after the Split-Off Date: (a) Each Group shall use all commercially reasonable efforts to make available to the other Group and its accountants, counsel, and other designated representatives, upon written request, its current and former directors,

officers, employees and representatives as witnesses, and shall otherwise cooperate with the other Group, to the extent reasonably required in connection with any Action or threatened Action arising out of either Group's business and operations in which the requesting party may from time to time be involved. (b) Each party hereto shall promptly notify the other party hereto, upon its receipt or the receipt by any of its Affiliates, of a request or requirement (by oral questions, interrogatories, requests for information or documents, subpoenas, civil investigative demands or other similar processes) which relates to the business and operations of the other party (a "Request") reasonably regarded as calling for the inspection or production of any documents or other information in its possession, custody or control, as received from any Person that is a party in any Action, or in the event the Person delivering the Request is not a party to such Action, as received from such Person. In addition to complying with the applicable provisions of Section 7.06, each party shall assert and maintain, or cause its Affiliates to assert and maintain, any applicable claim to privilege, immunity, confidentiality or protection in order to protect such documents and other information from disclosure, and shall seek to condition any disclosure which may be required on such protective terms as may be appropriate. No party may waive, undermine or fail to take any action necessary to preserve an applicable privilege without the prior written consent of the affected party hereto (or any affected Affiliate or Affiliates of any such party) except, in the opinion of such party's counsel, as required by law. (c) Each of Western, on its own behalf and on behalf of all members of the Western Group, and Westar, on its own behalf and on behalf of all members of the Westar Group, hereby waives any conflict which might preclude counsel currently representing Western, Westar or any of their respective Affiliates from representing Westar and/or any of its Affiliates following the Split-Off Date in connection with the Westar Litigation existing at the Merger Effective Time. (d) Western and Westar shall enter into such joint defense agreements, in customary form, as Western and Westar shall determine are advisable. Section 7.04. Reimbursement. Except to the extent that any member of one Group is obligated to indemnify any member of the other Group under Article V for that cost or expense, each Group providing information or witnesses to the other Group, or otherwise incurring any expense in connection with cooperating, under Sections 7.01, 7.02 or 7.03 shall be entitled to receive from the recipient thereof, upon the presentation of invoices therefor, payment for all out-of-pocket costs and expenses that may be incurred in providing such information, witnesses or cooperation. Section 7.05. Retention of Records. From and after the Split-Off Date, except as otherwise required by law or agreed to in writing, each party shall, and shall cause the members of its respective Group to, retain all information relating to the other Group's business and operations in accordance with the then general practice of such party with respect to information relating to its own business and operations but in any event for not less than seven years from the Separation Time. Notwithstanding the foregoing sentence, any party may destroy or otherwise dispose of any such information at any time, provided that, prior to such destruction or disposal, (i) such party shall provide not less than 90 calendar days' prior written notice to the other party, specifying the information proposed to be destroyed or disposed of and the scheduled date for such destruction or disposal, and (ii) if the recipient of such notice shall request in writing prior to the scheduled date for such destruction or disposal that any of the information proposed to be destroyed or disposed of be delivered to such requesting party, the party proposing the destruction or disposal shall promptly arrange for the delivery of such of the information as was requested at the expense of the requesting party. Section 7.06. Confidentiality. From and after the Split-Off Date, each party shall hold and shall cause its Affiliates and their respective directors, officers, employees, counsel, accountants, agents, consultants, advisors and other authorized representatives ("Representatives") to hold in strict confidence all documents and other information (other than any such documents and other information relating solely to the business or affairs of such party)

concerning the other party and/or its Affiliates ("Confidential Information") unless such party is compelled to disclose such documents and/or other information by judicial or administrative process or, in the opinion of its counsel, by other requirements of law or the rules of any applicable stock exchange. Confidential Information shall not include such documents and/or other information which can be shown to have been (A) in the public domain through no fault of such party, (B) lawfully acquired after the Split-Off Date on a non-confidential basis from other sources or (C) acquired or developed independently by such party without violating this Section 7.06 or the Confidentiality Agreements. Notwithstanding the foregoing, such party may disclose such Confidential Information to its Representatives so long as such Persons are informed by such party of the confidential nature of such Confidential Information and are directed by such party to treat such documents and/or other information confidentially. In the event that such party or any of its Representatives is requested or required (by oral questions, interrogatories, requests for information or documents, subpoenas, civil investigative demands or other similar processes) to disclose any of the Confidential Information, such party will promptly notify the other party so that the other party may seek a protective order or other remedy or waive such party's compliance with this Section 7.06. Such party shall exercise all commercially reasonable efforts necessary to preserve the confidentiality of the Confidential Information, including, but not limited to, by cooperating with the other party to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. If, in the absence of a protective order or other remedy or the absence of receipt of a waiver of the other party, such party or any of its Representatives is nonetheless legally compelled to disclose any of the Confidential Information, such party or such Representative may disclose only that portion of the Confidential Information which is legally required to be disclosed. Such party agrees to be responsible for any breach of this Section 7.06 by it and/or its Representatives. Section 7.07. Preservation of Privilege. The parties hereto recognize that as a consequence of the transactions contemplated by this Agreement or the Merger Agreement or the Ancillary Agreements, the parties may have common interests in the defense of certain pending or threatened litigation which may necessitate the exchange between the parties or their counsel of documents or other information that is subject to the attorney-client privilege, the work product doctrine or other legally recognized privileges, protections or immunities from discovery. Each party agrees to take in addition to, and not in limitation of, its obligations under Section 7.03(b) all commercially reasonable efforts necessary to protect and maintain, and to cause its Affiliates to protect and maintain, any applicable claim to privilege, immunity, protection or confidentiality in order to protect such documents and other information from improper disclosure or use. In addition to, and not in limitation of, its obligations under Section 7.03(b) and without limiting the generality of the foregoing, and to the maximum extent permitted by law, none of the parties or their respective Affiliates may waive or undermine, or fail to defend in a commercially reasonable manner, any privilege or protection or take or fail to take any other commercially reasonable action (a) that could result in the disclosure of any common-interest or joint-defense materials to any Person that is neither a party to this Agreement nor an Affiliate of any such party or (b) that would have the effect of waiving or undermining such privilege or protection, in either case, without the prior written consent of the affected party and any affected Affiliate of such affected party. Section 7.08. Inapplicability of Article VII to Tax Matters. Notwithstanding anything to the contrary in this Article VII, this Article VII shall not apply with respect to documents, other information and/or other matters relating to Taxes, all of which shall be governed by the Tax Disaffiliation Agreement.

From and after the Split-Off Date, each member of the Starco group will discontinue its use of the Western Resources name and logo and shall, as necessary, change the name of any Starco Subsidiary that incorporates the Western Resources name.

The parties agree to enter into and execute such additional Split-Off Documents as may be reasonably necessary, proper or advisable to effect the transactions contemplated by this Agreement or the Ancillary Agreements, provided, however, that such additional Split-Off Documents shall not diminish any of the rights granted or increase any of the Liabilities assumed under this Agreement or the Ancillary Agreements. Section 8.04. Third Party Beneficiaries. Parent shall be a third party beneficiary of this Agreement. Except as contemplated in the preceding sentence, nothing contained in this Agreement is intended to confer upon any Person or entity other than the parties hereto, Parent, and their respective successors and permitted assigns any benefit, right or remedies under or by reason of this Agreement, except that the provisions of Article V shall inure to the benefit of the Westar Indemnitees and the Western Indemnitees.

Section 9.04. Successors and Assigns. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided that neither party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of the other party, which consent shall not be unreasonably withheld, and unless the Merger Agreement shall have been terminated in accordance with its terms, any such assignment shall require the written consent of Parent.

To the extent that the provisions of this Agreement are inconsistent with the provisions of any other Ancillary Agreement, the provisions of such other Ancillary Agreement shall prevail. Section 9.08. Tax Disaffiliation Agreement; Set-Off; Payment of After-Tax Amounts; Certain Transfer Taxes. (a) Except as otherwise specifically provided herein and not inconsistent with the Tax Disaffiliation Agreement, this Agreement shall not govern any Tax matters, and any and all claims, losses, damages, demands, costs, expenses or liabilities relating to Taxes shall be exclusively governed by the Tax Disaffiliation Agreement. (b) If Western, Westar or any of their respective post-Separation Affiliates makes a payment pursuant to Section 5.01 or 5.02 of this Agreement, then (i) to the extent not already taken into account pursuant to the terms of this Agreement, such payment shall be reduced as provided in Section 5(f) of the Tax Disaffiliation Agreement if such payment gives rise to any Tax Asset (as such term is defined in the Tax Disaffiliation Agreement), and (ii) such Person shall also pay the recipient of such payment the related After-Tax Amount (as defined in the Tax Disaffiliation Agreement). This Section 9.08(b) shall be interpreted in accordance with the principles set forth in the Tax Disaffiliation Agreement and shall be subject to the dispute resolution provisions contained in Section 15 of the Tax Disaffiliation Agreement. (c) Except as otherwise provided in the Tax Disaffiliation Agreement, all transfer, documentary, sales, use, stamp and registration taxes and fees (including any penalties and interest) incurred in connection with any of the transactions described in Article II of this Agreement shall be borne and paid 50% by Western and 50% by Westar. The party that is required by applicable law to file any Return (as defined in the Tax Disaffiliation Agreement) or make any payment with respect to any of those taxes shall do so, and the other party shall cooperate with respect to that filing or payment as necessary. If Westar is required to make any payment, Western shall reimburse Westar in accordance with this Section 9.08, as appropriate, within 5 Business Days after it receives notice of the payment of those taxes. If Western is required to make any payment, Westar shall reimburse Western in accordance with this Section 9.08(c), as appropriate, within 5 Business Days after it receives notice of the payment of those taxes. This Section 9.08(c) shall be interpreted in accordance with the principles set forth in the Tax Disaffiliation Agreement and shall be subject to the dispute resolution provisions contained in Section 15 of the Tax Disaffiliation Agreement. Section 9.09. Jurisdiction. Except as otherwise expressly provided in this Agreement, any Action seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby may be brought in any U.S. federal or state court sitting in

Kansas, and each of the parties hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Action and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such Action in any such court or that any such Action which is brought in any such court has been brought in an inconvenient forum. Process in any such Action may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 9.01 shall be deemed effective service of process on such party. Section 9.10. Pre-Litigation Dispute Resolution. Prior to the bringing of any Action against the other, senior officers of Western and Westar shall confer, consult and in good faith attempt for a period of 30 calendar days to resolve any dispute between such parties relating to this Agreement or any of the Ancillary Agreements (other than the Tax Disaffiliation Agreement) without resort to legal remedies; provided that nothing in this Section 9.10 shall prohibit any party hereto or its Affiliates from bringing any Action if such party determines that any delay could reasonably be expected to prejudice such party's rights owing to any applicable statute of limitations or similar legal or equitable bar. Section 9.11. Severability. If any one or more of the provisions contained in this Agreement should be declared invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained in this Agreement shall not in any way be affected or impaired thereby so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a declaration, the parties shall modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner so that the transactions contemplated hereby are consummated as originally contemplated to the fullest extent possible. Section 9.12. Survival. All covenants and agreements of the parties contained in this Agreement and the Confidentiality Agreements shall survive the Split-Off Date indefinitely, unless a specific survival or other applicable period is expressly set forth therein. Section 9.13. Captions. The captions herein are included for convenience of reference only and shall be ignored in the construction or interpretation hereof. Section 9.14. Specific Performance. Each party to this Agreement acknowledges and agrees that monetary damages for a breach or threatened breach of any of the provisions of this Agreement would be inadequate and irreparable harm would occur. In recognition of this fact, each party agrees that, if there is a breach or threatened breach, in addition to any monetary damages, the other nonbreaching party to this Agreement, without posting any bond, shall be entitled to seek and obtain equitable relief in the form of specific performance, temporary restraining order, temporary or permanent injunction, attachment, or any other equitable remedy which may then be available to obligate the breaching party (i) to perform its obligations under this Agreement or (ii) if the breaching party is unable, for whatever reason, to perform those obligations, to take any other actions as are necessary, advisable or appropriate to give the other party to this Agreement the economic effect which comes as close as possible to the performance of those obligations (including, but not limited to, transferring, or granting liens on, the assets of the breaching party to secure the performance by the breaching party of those obligations). IN WITNESS WHEREOF the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the date first above written. WESTERN RESOURCES, INC.

RECITALS WHEREAS, PNM and Manzano Corporation, a New Mexico corporation ("Manzano"), have entered into an Agreement and Plan of Share Exchange, dated as of April 17, 2000 (the "Exchange Agreement"), which provides for the mandatory share exchange by the holders of the outstanding common stock of PNM for shares of the common stock of Manzano at an exchange ratio of one share of Manzano common stock for each share of PNM common stock, whereby PNM will become a wholly owned subsidiary of Manzano (the "Manzano Exchange"); WHEREAS, upon consummation of the Exchange, Manzano will execute a counterpart hereof as set forth below with the effect set forth herein (the date on which PNM becomes a Subsidiary of Manzano and Manzano executes a counterpart of this Agreement being referred to as the "Manzano Transition Date"); WHEREAS, the Company, Parent, PNM, Merger Sub-1 and Merger Sub-2 have agreed to enter into an integrated transaction (the "Transaction") pursuant to which, first (x) the Company shall deliver to its shareholders its then entire ownership interest in Westar Industries, Inc., a Kansas corporation and a subsidiary of the Company ("Westar", together with the subsidiaries of Westar at the time of the Split-Off, the "Westar Subsidiaries") (such transaction being referred to as the "Split-Off"), in exchange for a portion of their shares of the Company Common Stock on the terms and conditions contained herein and in the Asset Allocation and Separation Agreement (the "Allocation and Separation Agreement") and the other agreements and term sheets attached thereto (together with the Allocation and Separation Agreement, the "Split-Off Agreements") between the Company and Westar in the forms attached hereto as Exhibit A, and then (y) Merger Sub-1 will merge with and into the Company, whereby the Company will become a wholly owned subsidiary of Parent (the "Merger"), and Merger Sub-2 will merge with and into Manzano, whereby Manzano and PNM will become wholly owned subsidiaries of Parent (the "Second Merger" and, together with the Merger, the "Mergers"), pursuant to the terms and conditions set forth in this Agreement; WHEREAS, the respective Boards of Directors of the Company, Parent, PNM, Merger Sub-1 and Merger Sub-2 (i) have determined that the Transaction and other transactions contemplated hereby are fair to, advisable and in the best interests of the Company, Parent, PNM, Merger Sub-1 and Merger Sub-2 and their shareholders, respectively, and (ii) have approved this Agreement and the transactions contemplated hereby; and WHEREAS, for federal income Tax (as defined below) purposes, it is intended that (i) the Split-Off will be treated as a taxable exchange of the Split-Off Portion (as defined below) of the Company Common Stock for Westar Common Stock, and (ii) the Mergers taken together will be treated as a transaction described in Section 351 of the Internal Revenue Code of 1986, as amended (the "Code"). NOW, THEREFORE, in consideration of the premises, and of the representations, warranties, covenants and agreements contained herein, the parties hereto agree as follows: Article I The Transaction 1.1. The Split-Off. The Company has or will enter into the Allocation and Separation Agreement and each other Split-Off Agreement to which it is a party, and, provided that all conditions precedent to the Split-Off have been satisfied, immediately prior to the Merger, the Company shall effect, and cause Westar to effect, the Split-Off. 1.2. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, Merger Sub-1 shall be merged with and into the Company and the separate corporate existence of Merger Sub-1 shall thereupon cease. The Company shall be the surviving corporation in the Merger (sometimes hereinafter referred to as the "Surviving Corporation"), and the separate corporate existence of the Company with all its rights, privileges, immunities, powers and franchises shall continue unaffected by the Merger, except as set forth in Article III. The Merger shall have the effects specified in the Kansas General Corporation Code (the "KGCC"). 1.3. The Second Merger.

Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, Merger Sub-2 shall be merged with and into Manzano and the separate corporate existence of Merger Sub-2 shall thereupon cease. Manzano shall be the surviving corporation in the Second Merger, and the separate corporate existence of Manzano with all its rights, privileges, immunities, powers and franchises shall continue unaffected by the Second Merger. The Second Merger shall have the effects specified in the New Mexico Business Corporation Act (the "NMBCA"). 1.4. Effective Time. On the Closing Date (as defined in Section 4.1), or if not reasonably practicable, as soon as practicable following the Closing Date, the Company and Parent will cause a Certificate of Merger (the "Certificate of Merger") to be executed, acknowledged and filed with the Secretary of State of the State of Kansas as provided in Sections 17-6003 and 17-6701 of the KGCC. The Merger shall become effective at the time when the Certificate of Merger has been duly filed with the Secretary of State of the State of Kansas or upon such later date as agreed upon by the parties and specified in such Certificate of Merger (the "Effective Time"). Not later than simultaneously with the filing of the Certificate of Merger, Manzano and Parent will cause such certificates or other instruments to be filed with the New Mexico Public Regulation Commission (the "NMPRC") as are required in accordance with the NMBCA to cause the Second Merger to become effective at the Effective Time. Article II. The Surviving Corporation 2.1. The Articles of Incorporation. The restated articles of incorporation of the Company as in effect immediately prior to the Effective Time shall be the articles of incorporation of the Surviving Corporation (the "Charter"), until duly amended as provided therein or by applicable law. 2.2. The By-Laws. The by-laws of the Company as in effect immediately prior to the Effective Time shall be the by-laws of the Surviving Corporation (the "By-Laws"), until thereafter amended as provided therein or by applicable law. 2.3. Directors. The directors of Merger Sub-1 at the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Charter and the By-Laws. The directors of Merger Sub-1 at the Effective Time shall be appointed by Parent in its sole discretion, provided that at least three such directors shall be resident in the service territory of the Company or Kansas Gas and Electric Company in the State of Kansas. 2.4. Officers. The officers of Merger Sub-1 at the Effective Time shall, from and after the Effective Time, be the officers of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Charter and the By-Laws. Article III. Effect of the Transaction on Capital Stock; Exchange of Certificates 3.1. Apportionment of Company Common Stock.

(a) The Split-Off. At the Effective Time and in accordance with the terms hereof and of the Allocation and Separation Agreement, a portion (the "Split-Off Portion") of each share of common stock, par value $5.00 per share, of the Company (the "Company Common Stock") shall be exchanged for shares of common stock, par value $.01 per share, of Westar (the "Westar Common Stock"). The Split-Off Portion shall be calculated as follows: the market value of the shares of Westar Common Stock issued to and held by the Company divided by the market value of the total number of issued and outstanding shares of Company Common Stock, in each case immediately prior to the effective time of the Split-Off and determined based on the average (rounded to the nearest thousandth, or if there shall not be a nearest thousandth, the next highest thousandth) of the volume weighted averages (rounded to the nearest thousandth, or if there shall not be a nearest thousandth, the next highest thousandth) of the trading price of Westar Common Stock or Company Common Stock, as the case may be, on the New York Stock Exchange as reported by Bloomberg Financial Markets, or if not reported thereby, another reputable source, in the period of 20 consecutive Trading Days ending on the close of business on the second Business Day immediately preceding the effective time of the Split-Off; provided that if Westar Common Stock is not listed for trading on the New York Stock Exchange, the market price for Westar Common Stock shall be determined as the average of price quotes from three investment banking firms, one appointed by Westar, one appointed by the Company and the third by the two other appointees. (b) The Merger.

Days of receipt of the Adjustment Calculation. If Parent and the Company are unable to reach resolution of any differences with respect to the Adjustment Calculation within ten Business Days of receipt of Parent's written notice of dispute to the Company, Parent and the Company shall submit the amounts remaining in dispute to one of the five largest nationally recognized independent auditing firms selected by the Company but not to include the auditing firm who prepared the most recent audited financial statements for Parent or the Company (the "Neutral Auditor"). The Neutral Auditor shall be instructed to determine and report to the parties, within 20 Business Days after such submission, upon such remaining disputed amounts, and such report shall be final, binding and conclusive on the parties hereto with respect to the amounts disputed. The fees and disbursements of the Neutral Auditor shall be shared equally by Parent and the Company. (iii) The Merger Portion of each share of the Company Common Stock issued and outstanding immediately prior to the Effective Time (other than the Excluded Shares) shall be converted into, and become exchangeable for a number of shares of common stock, par value $0.001 per share of Parent (the "Parent Common Stock") equal to the Exchange Ratio (the "Merger Consideration" and together with the Split-Off Consideration, the "Closing Consideration"). The "Exchange Ratio" shall be equal to the Aggregate Share Number divided by the number of outstanding shares of Company Common Stock at the Effective Time (other than the Excluded Shares). (iv) Each Excluded Share shall, by virtue of the Split-Off and Merger and without any action on the part of the holder thereof, cease to be outstanding, shall be cancelled and retired without payment of any consideration therefor and shall cease to exist.

Upon surrender of a Certificate, or Manzano Certificate, as the case may be, (or evidence of loss in lieu thereof) for cancellation to the Exchange Agent together with such letter of transmittal, duly executed in accordance with the provisions of this Section 3.4(b), the holder of such Certificate, or Manzano Certificate, as the case may be, shall be entitled to receive in exchange therefor (x) Merger Consideration, in the case of the Merger, or, Manzano Merger Consideration, in the case of the Second Merger, in each case that such holder is entitled to receive pursuant to this Article III, and (y) a check in the amount (after giving effect to any required tax withholdings) of (A) any cash in lieu of fractional shares plus (B) any unpaid non-stock dividends and any other dividends or other distributions that such holder has the right to receive pursuant to the provisions of this Article III, and the Certificate, or Manzano Certificate, as the case may be, so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates, or Manzano Certificates, as the case may be. In the event of a transfer of ownership of shares of Company Common Stock or Manzano Common Stock that is not registered in the transfer records of the Company or Manzano, respectively, payment may be issued to such a transferee if the Certificate, or Manzano Certificate, as the case may be, formerly representing such shares of Company Common Stock or Manzano Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and the person requesting such issuance pays any transfer or other taxes required by reason of such payment to a person other than the registered holder of such Certificate, or Manzano Certificate, as the case may be, or establishes to the satisfaction of Parent and the Company that such tax has been paid or is not applicable. For the purposes of this Agreement, the term "person" shall mean any individual, corporation (including not-for-profit corporations), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity or other entity of any kind or nature. (c) Distributions with Respect to Unexchanged Shares; Voting.

No dividends or other distributions in respect of the Parent Common Stock shall be paid to any holder of any unsurrendered Certificate, or Manzano Certificate, as the case may be, until such Certificate, or Manzano Certificate, as the case may be, is surrendered for exchange in accordance with this Article IV. Following surrender of any Certificate, or Manzano Certificate, as the case may be, there shall be issued and/or paid to the holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (A) at the time of such surrender, the dividends and other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of Parent Common Stock and not paid with respect to such shares and (B) at the

appropriate payment date, the dividends and other distributions payable with respect to such whole shares of Parent Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender.

(d) Transfers, Etc. After the Effective Time, there shall be no transfers on the stock transfer books of the Company or Manzano of shares of Company Common Stock or Manzano Common Stock that were outstanding immediately prior to the Effective Time. (e) Fractional Shares. Notwithstanding any other provision of this Agreement to the contrary and solely for convenience and not as a separately bargained for consideration, no fractional shares of Parent Common Stock will be issued and any holder of shares of Company Common Stock entitled to receive a fractional share of Parent Common Stock but for this Section 3.4(e) shall be entitled to receive a cash payment in lieu thereof, as follows. The Exchange Agent will be directed to determine the number of whole shares and fractional shares of Parent Common Stock issuable to each holder of record of certificates formerly representing shares of Company Common Stock as of the Effective Time. Upon the determination by the Exchange Agent of such number of fractional shares, as soon as practicable after the Effective Time, the Exchange Agent, acting on behalf of the holders thereof, shall sell such fractional shares for cash on the open market in each case at the then prevailing market prices and shall distribute to each holder entitled thereto, in lieu of any fractional share, without interest, that holder's ratable share of the proceeds of that sale, after making appropriate deductions of the amount required, if any, to be withheld for United States income Tax purposes. (f) Termination of Exchange Fund. Any portion of the Exchange Fund relating to the Merger Consideration in the case of the Merger or the Manzano Merger Consideration, in the case of the Second Merger that remains unclaimed by the shareholders of the Company or the shareholders of Manzano for one year after the Effective Time shall be returned to Parent. At the same time, any portion of the Exchange Fund comprised of Split-Off Consideration shall be returned to Westar. Any shareholders of the Company or of Manzano who have not theretofore complied with this Article III shall thereafter look only to (i) Parent for payment of the Merger Consideration in the case of the Merger, or Manzano Merger Consideration, in the case of the Second Merger, and any cash, dividends and other distributions in respect thereof payable and/or issuable pursuant to Section 3.2 and Section 3.4(c) upon due surrender of their Certificates, or Manzano Certificates, as the case may be, (or affidavits of loss in lieu thereof), and (ii) Westar for payment of the Split-Off Consideration, in each case, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Surviving Corporation, Manzano, Westar, the Exchange Agent or any other person shall be liable to any former holder of shares of Company Common Stock or Manzano Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. (g) Lost, Stolen or Destroyed Certificates. In the event that any Certificate, or Manzano Certificate, as the case may be, shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate, or Manzano Certificate, as

the case may be, to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond in customary amount as indemnity against any claim that may be made against it with respect to such Certificate, or Manzano Certificates, as the case may be, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate, or Manzano Certificate, as the case may be, the Closing Consideration in the case of the Merger and the Split-Off, or the Manzano Merger Consideration, in the case of the Second Merger, and, if applicable, any cash payable and any unpaid dividends or other distributions deliverable in respect thereof pursuant to Section 3.4(c) upon due surrender of the shares of the Company Common Stock or Manzano Common Stock represented by such Certificate, or Manzano Certificate, as the case may be, pursuant to this Agreement. (h) Affiliates. Notwithstanding anything herein to the contrary, Certificates surrendered by any "affiliate" (as determined pursuant to Section 7.6) of the Company shall not be exchanged until Parent shall have received a written agreement from such person as provided for in Section 7.6 hereof. 3.5. Dissenters' Rights. (a) In the event that appraisal rights are available under Section 17-6712 of the KGCC to holders of shares of the Company Common Stock at the Effective Time, any issued and outstanding shares of the Company Common Stock held by a person who objects to the Transaction and complies with all applicable provisions of the KGCC concerning the right of such person to dissent from the Transaction and demands appraisal of shares ("Company Dissenting Holder") shall from and after the Effective Time represent only the right to receive such consideration as may be determined to be due to such Company Dissenting Holder with respect to such shares pursuant to the KGCC and shall not be converted as described in Section 3.2(b); provided, however, that shares outstanding immediately prior to the Effective Time and held by a Company Dissenting Holder who shall withdraw the demand for appraisal or lose the right of appraisal of such shares pursuant to the KGCC shall be deemed to be converted, as of the Effective Time, into the right to receive the Closing Consideration. (b) Any issued and outstanding shares of Manzano Common Stock held by a person who objects to the Second Merger and complies with all applicable provisions of the NMBCA concerning the right of such person to dissent from the Second Merger and demands appraisal of such shares ("Manzano Dissenting Holder") shall from and after the Effective Time represent only the right to receive such consideration as may be determined to be due to such Manzano Dissenting Holder with respect to such shares pursuant to the NMBCA and shall not be converted as described in Section 3.2(c); provided, however, that shares outstanding immediately prior to the Effective Time and held by a Manzano Dissenting Holder who shall withdraw the demand for appraisal, or lose the right of appraisal of such shares pursuant to the NMBCA shall be deemed to be converted, as of the Effective Time, into the right to receive the Manzano Merger Consideration. 3.6. Adjustments to Prevent Dilution. In the event that the Company changes the number of shares of Company Common Stock or securities convertible or exchangeable into or exercisable for shares of Company Common Stock (other than the issuance of Convertible Preference Shares), Manzano changes the number of shares of Manzano Common Stock or securities convertible or exchangeable for shares of Manzano Common Stock, or Parent changes the number of shares of Parent Common Stock or securities convertible or exchangeable into or exercisable for shares of Parent Common Stock, in each case issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction, the Closing Consideration, the Exchange Ratio and the Split-Off Exchange Ratio shall be equitably adjusted to reflect such change in the case of the Merger and the Split-Off, and the number of shares of Parent Common Stock into which each share of Manzano Common Stock shall be converted shall be equitably adjusted to

reflect such change, in the case of the Second Merger. 3.7. Restructuring of the Mergers. If for any reason, the Manzano Transition Date can not occur, or the regulatory approvals required to permit it to occur are likely to materially delay the Effective Time, then the parties agree to restructure certain of the transactions contemplated hereby and to exclude Manzano from participation in the transactions contemplated hereby. In such event, PNM and Parent, in lieu of the Manzano Exchange and the Second Merger, as provided for herein, shall enter into an agreement and plan of share exchange (the "PNM Exchange Agreement") (which agreement shall be substantially the same as the Exchange Agreement with such changes therein as are appropriate to reflect Parent's status as a Delaware corporation, except that Article VI of the Exchange Agreement shall be modified to require all holders to surrender their certificates for cancellation or cancellation and transfer) pursuant to which (i) the Exchange Agreement would be terminated and the Manzano Exchange abandoned, (ii) at the Effective Time, each share of PNM Common Stock would be automatically converted into shares of Parent Common Stock based on the Manzano Exchange Ratio (the "PNM Exchange") and Parent would thereby acquire and become the owner and holder of each issued and outstanding share of PNM Common Stock. In the event the Manzano Transition Date does not occur prior to the Effective Time, PNM shall retain all of its rights, obligations, interests and liabilities under this Agreement. The Parties recognize that there may be other circumstances in which it may be preferable to effectuate a business combination between Parent, PNM and the Company by means of an alternative structure to the Transaction. Accordingly, if, prior to satisfaction of the conditions contained in Article VIII hereto, either party proposes the adoption of an alternative structure that will not delay the Effective Time and that otherwise substantially preserves for Parent, PNM, the Company and the holders of the Company Common Stock the economic and Tax benefits of the Transactions, then the parties shall make good faith to effect a business combination among themselves by means of a mutually agreed upon structure other than the Transactions that so preserves such benefits; provided that if the Company Requisite Vote or the Parent Requisite Vote has already been obtained, such alternative business combination does not require any additional approval of the shareholders of the Company under the KGCC or other applicable law or the shareholders of PNM under the NMBCA or other applicable law. In the event that the parties adopt a restructured transaction, the Agreement shall be revised to reflect such transaction as determined necessary by the parties hereto and prior to closing any such restructured transaction, all material third party and Governmental Authority declarations, filings, registrations, notices, authorizations, consents or approvals necessary for the effectuation of such alternative business combination shall have been obtained and all other conditions to the parties' obligations to consummate the Transaction and other transactions contemplated hereby, as applied to such alternative business combination, shall have been satisfied or waived. 3.8. Manzano Guaranty; Etc. Effective from the Manzano Transition Date, (i) Manzano unconditionally guarantees the obligations of Parent under this Agreement but only through the Effective Time, it being the intent of the parties that such obligations shall be obligations solely of Parent from and after the Effective Time and (ii) Manzano assumes and agrees to perform all obligations of PNM hereunder and shall succeed to all rights, interests and liabilities of PNM hereunder and be substituted for PNM for all purposes of this Agreement as if originally named herein, in each case without necessity for further act by any party hereto. Manzano agrees promptly to execute a counterpart of this Agreement upon PNM becoming its Subsidiary. PNM agrees to give written notice to all other parties hereto of the occurrence of the Manzano Transition Date. Article IV. The Closing 4.1. Closing.

The closing of the Transaction (the "Closing") shall take place (i) at the offices of LeBoeuf, Lamb, Greene & MacRae, L.L.P., 125 West 55th Street, New York, New York at 10:00 A.M. on the twentieth Business Day after the last to be satisfied or waived of the conditions set forth in Article VIII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions) shall be satisfied or waived (by the party entitled to the benefit of such condition) in accordance with this Agreement or (ii) at such other place and time and/or on such other date as the Company and Parent may agree in writing (the "Closing Date"); provided that in the event a dispute resolution process pursuant to Section 3.2(b)(ii)(B) is pending, the Closing Date shall automatically be extended to two business days following the date of delivery of the report of the Neutral Auditor. For purposes of this Agreement, the term "Business Day" means a day on which banks are not required or authorized by law to close in New York City. Article V. Representations and Warranties 5.1. Representations and Warranties of the Company. Except as set forth in the disclosure letter delivered to Parent by the Company on or prior to entering into this Agreement (the "Company Disclosure Letter") or the Company Reports, the Company hereby represents and warrants to Parent, PNM, Merger Sub-1 and Merger Sub-2 that: (a) Organization, Good Standing and Qualification.

Wolf Creek Nuclear Operating Corporation is a corporation in good standing under the laws of the state of Kansas. The Company has made available to Parent complete and correct copies of the Company's and each of its Utility Subsidiaries' articles of incorporation and by-laws (or comparable governing instruments), as amended to date.

(e) Company Reports; Financial Statements. (i) The filings required to be made (A) by the Company and its Subsidiaries

since January 1, 1999 under the Securities Act; the Exchange Act; the 1935 Act; the Federal Power Act; and applicable state public utility laws and regulations have been filed with the SEC, FERC, or the appropriate state public utilities commission, as the case may be, and (B) by Wolf Creek Nuclear Operating Corporation since January 1, 1999 under the Atomic Energy Act of 1954, as amended, to the knowledge of the Company, have been filed with the NRC, including all forms, statements, reports, agreements (oral or written) and all documents, exhibits, amendments and supplements appertaining thereto, and complied, as of their respective dates, in all material respects with all applicable requirements of the appropriate statutes and the rules and regulations thereunder, except for such filings the failure of which to have been made or so to comply would not result in a Company Material Adverse Effect. The Company has made available to Parent each registration statement, report, proxy statement or information statement filed by it with the SEC (collectively, including any amendments of any such reports, the "Company Reports") pursuant to the Securities Act or the Exchange Act since January 1, 1999, and prior to the date hereof, including (i) the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 1999 and (ii) the Company's Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2000 and June 30, 2000, each in the form (including exhibits, annexes and any amendments thereto) promulgated by the SEC under the Securities Act or the Exchange Act. None of the Company Reports (in the case of Company Reports filed pursuant to the Securities Act), as of their effective dates, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading and none of the Company Reports (in the case of Company Reports filed pursuant to the Exchange Act) as of the respective dates filed with the SEC or first mailed to shareholders, as applicable, contained any statement which, at the time and in the light of the circumstances under which it was made, was false or misleading with respect to any material fact, or omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The consolidated financial statements of the Company and its Subsidiaries included in such Company Reports comply as to form in all material respects with the applicable rules and regulations of the SEC with respect thereto. Each of the consolidated balance sheets included in or incorporated by reference into the Company Reports (including the related notes and schedules) presents fairly, in all material respects, the financial position of the Company and its Subsidiaries as of its date and each of the consolidated statements of income and consolidated statements of cash flow included in or incorporated by reference into the Company Reports (including any related notes and schedules) fairly presents in all material respects the results of operations, retained earnings and changes in financial position, as the case may be, of the Company and its Subsidiaries for the periods set forth therein (subject, in the case of unaudited statements, to the absence of notes and normal year-end audit adjustments), in each case in accordance with GAAP consistently applied during the periods involved, except as may be noted therein. (ii) Section 5.1(e)(ii) of the Company Disclosure Letter contains the unaudited pro forma consolidated balance sheet of the Company and its Utility Subsidiaries as of September 30, 2000, which presents information as if the Split-Off had occurred (on the terms and subject to the conditions set forth in the Split-Off Agreements) as of the Audit Date. Such balance sheet is based on, and should be read in conjunction with, the historical consolidated financial statements included in the Company Reports. Such balance sheet fairly presents in all material respects the consolidated financial position of the Company and its Subsidiaries as of its date, as if the Split-Off had occurred (on the terms and subject to the conditions set forth in the Split-Off Agreements) on such date, subject to notes and normal year-end audit adjustments that will not be material in amount or effect. The accounts reflected in the unaudited pro forma balance sheet referred to in this subsection have been prepared in accordance with GAAP on a basis consistent with the historical audited consolidated balance sheets of the Company and its Subsidiaries (including the Split-Off Subsidiaries) and were prepared in accordance with the requirements of SEC Regulation S-X as it relates to pro forma balance sheets. (f) Absence of Certain Changes.

Since December 31, 1999 (the "Audit Date"), except as expressly contemplated by this Agreement and the Split-Off Agreements, the Company and its Subsidiaries taken as a whole have conducted their business only in, and have not engaged in any material transaction other than according to, the ordinary and usual course of such business and there has not been (i) any change in the financial condition, properties, assets, business or results of operations of the Company and its Subsidiaries that has had or would be reasonably likely to have a Company Material Adverse Effect; (ii) any declaration, setting aside or payment of any dividend or other distribution in respect of the capital stock of the Company or any repurchase, redemption or other acquisition by the Company or any Subsidiary of any securities of the Company other than regular quarterly dividends on shares of the Company Common Stock in the ordinary course (including any periodic increase thereon consistent with past practice); or (iii) any change by the Company in accounting principles, practices or methods which is not required or permitted by GAAP. Since the Audit Date and through the date hereof, except as provided for herein, there has not been any material increase in the compensation payable or that could become payable by the Company or any of its Subsidiaries to officers or key employees or any material amendment of any of the Compensation and Benefit Plans other than increases or amendments in the ordinary course of business consistent with past practice. (g) Litigation. (i) There are no civil, criminal or administrative actions, suits, claims, hearings, investigations, reviews or proceedings pending or, to the knowledge of the Company, threatened against the Company or any of its Utility Subsidiaries, except for those that would not be reasonably likely to have, either individually or in the aggregate, a Company Material Adverse Effect. (ii) To the knowledge of the Company, there are no civil, criminal or administrative actions, suits, claims, hearings, investigations, reviews or proceedings pending or threatened against Wolf Creek Nuclear Operating Corporation, except for those that would not be reasonably likely to have, either individually or in the aggregate, a Company Material Adverse Effect. (h) Employee Benefits. (i) A copy of (i) each bonus, deferred compensation, pension, retirement, profit-sharing, thrift, savings, employee stock ownership, stock bonus, stock purchase, change in control, retention, restricted stock, stock option, employment, termination, severance, compensation, medical, health or other plan, agreement, policy, practice or arrangement that covers employees or former employees of the Company and its Subsidiaries ("Employees"), or directors or former directors of the Company (the "Compensation and Benefit Plans"); and (ii) any trust agreement or insurance contract forming a part of such Compensation and Benefit Plans has been made available to Parent prior to the date hereof. Section 5.1(h) of the Company Disclosure Letter lists all Compensation and Benefit Plans other than those that, in the aggregate, are not material to the Company and its Subsidiaries and any Compensation and Benefit Plans containing "change of control" or similar provisions therein are specifically identified in Section 5.1(h) of the Company Disclosure Letter. (ii) All Compensation and Benefit Plans, to the extent subject to the Employee Retirement Income Security Act of 1974, as amended ("ERISA") are in substantial compliance with the applicable provisions of ERISA. Each Compensation and Benefit Plan that is an "employee pension benefit plan" within the meaning of Section 3(2) of ERISA (a "Company Pension Plan") and that is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service (the "IRS"), and nothing has occurred, whether by action or failure to act, that would cause the loss of such qualification or that would result in costs to the Company or any of its Subsidiaries under the Internal Revenue Service's Employee Plans Compliance Resolution System that would be reasonably likely to have a Company Material Adverse Effect. As of the date

hereof, there is no material pending or to the knowledge of the Company threatened litigation relating to the Compensation and Benefit Plans. Neither the Company nor any of its Subsidiaries nor, to the knowledge of the Company, any other person has engaged in a transaction with respect to any Compensation and Benefit Plan that, assuming the taxable period of such transaction expired as of the date hereof, would subject the Company or any of its Subsidiaries to a material tax or penalty imposed by either Section 4975 of the Code or Section 502(i) of ERISA. (iii) No liability under Subtitle C or D of Title IV of ERISA has been or is expected to be incurred by the Company or any of its Subsidiaries with respect to any ongoing, frozen or terminated "single-employer plan", within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or the single-employer plan of any entity which is considered one employer with the Company under Section 4001 of ERISA or Section 414 of the Code (a "Company ERISA Affiliate"). The Company and its Subsidiaries have not incurred and do not expect to incur and would not expect to incur any withdrawal liability with respect to a multiemployer plan under Subtitle E of Title IV of ERISA (regardless of whether based on contributions of a Company ERISA Affiliate) if, as of the date hereof, the Company or a Company ERISA Affiliate were to engage in a "complete withdrawal" (as defined in Section 4203 of ERISA) or a "partial withdrawal" (as defined in Section 4205 of ERISA) from such multiemployer plan. No notice of a "reportable event", within the meaning of Section 4043 of ERISA for which the 30-day reporting requirement has not been waived or extended, other than the extension provided by PBGC Reg. Section 4043.66, has been required to be filed for any Company Pension Plan or by any Company ERISA Affiliate within the 12-month period ending on the date hereof. (iv) All contributions required to be made under the terms of any Compensation and Benefit Plan as of the date hereof have been timely made or have been reflected on the most recent consolidated balance sheet filed or incorporated by reference in the Company Reports and all premium payments to the Pension Benefit Guaranty Corporation ("PBGC") have been made when due for such plans. Neither any Company Pension Plan nor any single-employer plan of a Company ERISA Affiliate has an "accumulated funding deficiency" (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of ERISA and no Company ERISA Affiliate has an outstanding funding waiver. Neither the Company nor any of its Subsidiaries has provided, or is required to provide, security to any Company Pension Plan or to any single-employer plan of a Company ERISA Affiliate pursuant to Section 401(a)(29) of the Code. (v) Neither the Company nor its Subsidiaries have any obligations for, or liabilities with respect to, retiree health and life benefits under any Compensation and Benefit Plan, except for benefits required to be provided under Section 4980B of the Code. (vi) Notwithstanding anything to the contrary contained in this Section 5.1(h), the representations and warranties contained in this Section 5.1(h) shall be deemed to be true and correct unless such failures to be true and correct are reasonably likely to have a Company Material Adverse Effect. (i) Compliance with Laws. As of the date hereof, the business of the Company and its Subsidiaries, taken as a whole, is not being conducted in violation of any federal, state, local or foreign law, statute, ordinance, rule, regulation, judgment, order, injunction, decree, arbitration award, agency requirement, license or permit of any Governmental Entity (collectively, "Laws"), except for violations that would not be reasonably likely to have, either individually or in the aggregate, a Company Material Adverse Effect or prevent or materially impair the ability of the Company to consummate the transactions contemplated by this Agreement. As of the date hereof, no investigation or review by any Governmental Entity with respect to the Company or any of its Subsidiaries is pending or, to the knowledge of the Company, threatened, nor has any Governmental Entity indicated

an intention to conduct the same, except for those the outcome of which would not be reasonably likely to have, either individually or in the aggregate, a Company Material Adverse Effect or prevent or materially impair the ability of the Company to consummate the transactions contemplated by this Agreement. The Company and each of its Utility Subsidiaries each has all permits, licenses, franchises, variances, exemptions, orders and other governmental authorizations, consents and approvals from Governmental Entities necessary to conduct its business as presently conducted, except for those the absence of which would not be reasonably likely to have, either individually or in the aggregate, a Company Material Adverse Effect or prevent or materially impair the ability of the Company to consummate the transactions contemplated by this Agreements. (j) Takeover Statutes. Assuming the accuracy of the representation contained in Section 5.2(q), no business combination, control share, fair price, moratorium or similar anti-takeover provision (a "Takeover Statute") of the KGCC or any applicable anti-takeover provision in the certificate of incorporation of the Company or the bylaws of the Company is applicable to the Transaction or any other transaction contemplated hereby.

Except for the representations and warranties contained in this Section 5.1, neither the Company nor any other Person makes any other express or implied representation or warranty on behalf of the Company or any of its Subsidiaries. 5.2. Representations and Warranties of Parent, PNM, Merger Sub-1 and Merger Sub-2. Except as set forth in the disclosure letter delivered to the Company by Parent on or prior to entering into this Agreement (the "Parent Disclosure Letter") or the PNM Reports, Parent, PNM, Merger Sub-1 and Merger Sub-2 each represents and warrants to the Company that: (a) Capitalization of Merger Sub-1 and Merger Sub-2. The authorized capital stock of Merger Sub-1 consists of 40,000,000 shares of common stock, no par value, of which one was issued and outstanding on the date hereof and 10 million shares of preferred stock, no par value. The authorized capital stock of Merger Sub-2 consists of 1,000 shares of common stock, no par value, of which one was issued and outstanding on the date hereof. All of the issued and outstanding capital stock of Merger Sub-1 and Merger Sub-2 is, and at the Effective Time will be, owned by Parent, and there are (i) no other shares of capital stock or voting securities of Merger Sub-1 and Merger Sub-2 authorized, (ii) no securities of Merger Sub-1 and Merger Sub-2 convertible into or exchangeable for shares of capital stock or voting

Merger Sub-1 and Merger Sub-2 have not conducted any business prior to the date hereof and has no, and prior to the Effective Time will have no, assets, liabilities or obligations of any nature other than those incident to its formation and pursuant to or in connection with the this Agreement and the transactions contemplated hereby. (b) Organization, Good Standing and Qualification. Each of Parent and its Significant Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of its respective jurisdiction of organization and has all requisite corporate or similar power and authority to own and operate its material properties and assets and to carry on its business as presently conducted in all material respects and is qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the ownership or operation of its properties or conduct of its business requires such qualification, except where the failure to be so qualified as a foreign corporation or be in good standing would not be reasonably likely to have, either individually or in the aggregate, a Parent Material Adverse Effect. Parent has made available to the Company a complete and correct copy of Parent's, Manzano's and PNM's and its Significant Subsidiaries' certificates of incorporation and by-laws (or comparable governing instruments), as amended to date and the certificate of incorporation and by-laws of Parent are set forth in Section 5.2(b) of the Parent Disclosure Schedule. Parent's, Manzano's and PNM's and its Significant Subsidiaries' certificates of incorporation and by-laws (or comparable governing instruments) so delivered are in full force and effect. As used in this Agreement, the term "Parent Material Adverse Effect" means a material adverse effect on the financial condition, business, assets or results of operations of Manzano and PNM and their Subsidiaries taken as a whole; provided, however, that any such effect resulting from or arising out of (i) any change in law, rule, regulation or GAAP or interpretations thereof, (ii) economic or business conditions in the United States generally, (iii) conditions generally affecting the electric or gas utility industries or (iv) the execution and delivery of this Agreement, or the contemplated consummation of the transactions contemplated hereby, shall not be considered when determining if a Parent Material Adverse Effect has occurred. (c) Capital Structure. The authorized capital stock of PNM consists of (x) 80,000,000 shares of common stock, par value $5.00 per share ("PNM Common Stock"), of which 39,082,599 shares were issued and outstanding on November 6, 2000, and (y) 10,000,000 shares of preferred stock (the "PNM Preferred Shares"), of which 128,000 shares were issued and outstanding on November 6, 2000. All of the issued and outstanding shares of PNM Common Stock and PNM Preferred Shares have been duly authorized and are validly issued, fully paid and nonassessable. The authorized capital stock of Parent consists of 200,000,000 shares of Parent Common Stock, one of which was issued and outstanding on the date hereof and 10,000,000 shares of preferred stock, none of which were outstanding on the date hereof. The authorized capital stock of Manzano consists of 120,000,000 shares of Manzano Common Stock, 100 of which were issued and outstanding on the date hereof. Each of the outstanding shares of capital stock or other securities of each of PNM's Subsidiaries is duly authorized, validly issued, fully paid and nonassessable and owned by PNM or a direct or indirect wholly-owned Subsidiary of PNM, free and clear of any lien, pledge, security interest, claim or other encumbrance. Other than pursuant to the First Restated and Amended Director Retainer Plan, the Third Restated and Amended Performance Stock Plan, the Manzano Omnibus Performance Equity Plan and the PNM Direct Plan (the "Parent Stock Plans"), there are no preemptive or other outstanding rights, options, warrants, conversion rights, stock appreciation rights, redemption rights, repurchase rights, agreements, arrangements or commitments to issue or to sell any shares of capital stock or other securities of Parent, PNM or Manzano or any

of their Subsidiaries or any securities or obligations convertible or exchangeable into or exercisable for, or giving any Person a right to subscribe for or acquire, any securities of Parent, Manzano, PNM or any of its Subsidiaries, and no securities or obligations evidencing such rights are authorized, issued or outstanding. Parent, PNM and Manzano do not have outstanding any bonds, debentures, notes or other obligations the holders of which have the right to vote (or convertible into or exercisable for securities having the right to vote) with the shareholders of Parent on any matter ("Parent Voting Debt"). (d) Corporate Authority and Approval. (i) Each of Parent, Manzano, PNM, Merger Sub-1 and Merger Sub-2 has all requisite corporate power and authority and has taken all corporate action necessary in order to execute, deliver and perform its obligations under this Agreement, and to consummate, subject only to the receipt of the Parent Requisite Vote and the Parent Required Statutory Approvals, the transactions contemplated hereby. This Agreement has been duly executed and delivered by Parent, Manzano, PNM, Merger Sub-1 and Merger Sub-2 and, assuming due authorization, execution and delivery by the Company, is a valid and legally binding agreement of Parent, Manzano, PNM, Merger Sub-1 and Merger Sub-2, enforceable against each of Parent, PNM, Merger Sub-1 and Merger Sub-2 in accordance with its terms, subject to the Bankruptcy and Equity Exception. (ii) As of the date hereof, the Board of Directors of Parent, Manzano, PNM, Merger Sub-1 and Merger Sub-2 have approved and adopted this Agreement and the Mergers and other transactions set forth herein, and subject to their respective fiduciary duties, the Boards of Directors of PNM and Manzano have resolved to recommend that the shareholders of PNM and Manzano approve this Agreement and the transactions contemplated hereby. (iii) Prior to the Effective Time, Parent will have taken all necessary action to permit it to issue the number of shares of Parent Common Stock required to be issued pursuant to Article III and upon conversion of any Parent Convertible Shares held by Westar. The Parent Common Stock, when issued, will be validly issued, fully paid and nonassessable, and no shareholder of Parent will have any preemptive right of subscription or purchase in respect thereof. The Parent Common Stock, when issued, will be registered under the Securities Act and Exchange Act and registered or exempt from registration under any applicable state securities or "blue sky" laws. (e) Governmental Filings; No Violations. (i) Other than any reports, filings, registrations, approvals and/or notices (A) required to be made pursuant to Section 1.4, (B) required to be made under the HSR Act, the Securities Act and the Exchange Act, (C) with, to or of the SEC under the 1935 Act, (D) with, to or of the FERC, (E) with or to the Nuclear Regulatory Commission, (F) with or to the Federal Communications Commission, (G) with or to the NMPRC, (H) to comply with state securities or "blue sky" laws, and (I) required to be made with the NYSE, (items B through I, the "Parent Required Statutory Approvals"), no notices, reports, registrations or other filings are required to be made by Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 with, nor are any consents, registrations, approvals, permits or authorizations required to be obtained by Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 from, any Governmental Entity, in connection with the execution and delivery of this Agreement by Parent, Manzano, PNM, Merger Sub-1 and Merger Sub-2 and the consummation by Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 of the Mergers and the other transactions contemplated hereby, except for those that the failure to make or obtain would not be reasonably likely to have, either individually or in the aggregate, a Parent Material Adverse Effect or prevent, materially delay or materially impair the ability of Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 to consummate the transactions contemplated hereby.

(ii) The execution, delivery and performance of this Agreement by Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 do not, and the consummation by Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 of the Merger and the other transactions contemplated hereby will not, constitute or result in (A) breach or violation of, or a default under, either the certificate of incorporation or by-laws of Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 or the comparable governing instruments of any of PNM's Significant Subsidiaries, (B) a breach or violation of, or a default under, the acceleration of any obligations, the loss of any right or benefit or the creation of a lien, pledge, security interest or other encumbrance on the assets of PNM or any of its Significant Subsidiaries (with or without notice, lapse of time or both) pursuant to any Contracts binding upon PNM or any of its Significant Subsidiaries (the "Parent Contracts") or any Law or governmental or non-governmental permit or license to which PNM or any of its Significant Subsidiaries is subject or (C) any change in the rights or obligations of any party under any of the Parent Contracts, except, in the case of clause (B) or (C) above, for any breach, violation, default, acceleration, creation or change that would not be reasonably likely to have, either individually or in the aggregate, a Parent Material Adverse Effect or prevent, materially delay or materially impair the ability of Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 to consummate the transactions contemplated hereby. (f) PNM Reports; Financial Statements. The filings required to be made by PNM and its Subsidiaries since January 1, 1999 under the Securities Act; the Exchange Act; the 1935 Act; the Federal Power Act; the Atomic Energy Act of 1954, as amended, and applicable state public utility laws and regulations have been filed with the SEC, FERC, the NRC or the appropriate state public utilities commission, as the case may be, including all forms, statements, reports, agreements (oral or written) and all documents, exhibits, amendments and supplements appertaining thereto, and complied, as of their respective dates, in all material respects with all applicable requirements of the appropriate statutes and the rules and regulations thereunder, except for such filings the failure of which to have been made or so to comply would not result in a Parent Material Adverse Effect. PNM has made available to the Company each registration statement, report, proxy statement or information statement filed by it with the SEC (collectively, including any amendments of any such reports, the "PNM Reports") pursuant to the Securities Act or the Exchange Act since December 31, 1999, and prior to the date hereof, including (i) PNM Annual Report on Form 10-K for the fiscal year ended December 31, 1999 and (ii) PNM Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2000 and June 30, 2000, each in the form (including exhibits, annexes and any amendments thereto) promulgated by the SEC under the Securities Act or the Exchange Act. None of the PNM Reports (in the case of PNM Reports filed pursuant to the Securities Act), as of their effective dates, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading and none of the PNM Reports (in the case of PNM Reports filed pursuant to the Exchange Act) as of the respective dates first mailed to shareholders contained any statement which, at the time and in the light of the circumstances under which it was made, was false or misleading with respect to any material fact, or omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The consolidated financial statements of the PNM and its Subsidiaries included in such PNM Reports comply as to form in all material respects with the applicable rules and regulations of the SEC with respect thereto. Each of the consolidated balance sheets included in or incorporated by reference into the PNM Reports (including the related notes and schedules) presents fairly, in all material respects, the financial position of the PNM and its Subsidiaries as of its date and each of the consolidated statements of income and consolidated statements of cash flow included in or incorporated by reference into the PNM Reports (including any related notes and schedules) fairly presents in all material respects the results of operations, retained earnings and changes in financial position, as the case may be, of the PNM and its Subsidiaries for the periods set forth therein (subject, in the case of

unaudited statements, to the absence of notes and normal year-end audit adjustments), in each case in accordance with GAAP consistently applied during the periods involved, except as may be noted therein. (g) Absence of Certain Changes. Since the December 31, 1999 (the "PNM Audit Date"), PNM and its Subsidiaries, taken as a whole, have conducted their business only in, and have not engaged in any material transaction other than according to, the ordinary and usual course of such business and there has not been (i) any change in the financial condition, properties, assets, business or results of operations of PNM and its Subsidiaries that has had or would be reasonably likely to have a Parent Material Adverse Effect; (ii) any declaration, setting aside or payment of any dividend or other distribution in respect of the capital stock of PNM or any repurchase, redemption or other acquisition by PNM or any Subsidiary of any securities of PNM other than quarterly dividends in the ordinary course (including any increase thereon consistent with past practice); or (iii) any change by PNM in accounting principles, practices or methods which is not required or permitted by GAAP. Since the PNM Audit Date and through the date hereof, except as provided for herein or as disclosed in the PNM Reports, there has not been any material increase in the compensation payable or that could become payable by PNM or any of its Subsidiaries to officers or key employees or any material amendment of any of the PNM Compensation and Benefit Plans other than increases or amendments in the ordinary course of business consistent with past practice. (h) Litigation. There are no civil, criminal or administrative actions, suits, claims, hearings, investigations, reviews or proceedings pending or, to the knowledge of Parent and PNM, threatened against Parent, PNM, or any of its Significant Subsidiaries, except for those that would not be reasonably likely to have, either individually or in the aggregate, a Parent Material Adverse Effect. (i) Employee Benefits. (i) A copy of (i) each bonus, deferred compensation, pension, retirement, profit-sharing, thrift, savings, employee stock ownership, stock bonus, stock purchase, change in control, retention, restricted stock, stock option, employment, termination, severance, compensation, medical, health or other plan, agreement, policy, practice or arrangement that covers employees or former employees of PNM and Parent and their Subsidiaries ("Parent Employees"), or directors or former directors of PNM or Parent (the "Parent Compensation and Benefit Plans"); and (ii) any trust agreement or insurance contract forming a part of such PNM Compensation and Benefit Plans has been made available to the Company prior to the date hereof. Section 5.2(i) of the Parent Disclosure Letter lists all Parent Compensation and Benefit Plans other than those that, in the aggregate, are not material to PNM or Parent and their Subsidiaries and any Parent Compensation and Benefit Plans containing "change of control" or similar provisions therein are specifically identified in Section 5.2(i) of the Parent Disclosure Letter. (ii) All Parent Compensation and Benefit Plans, to the extent subject to ERISA are in substantial compliance with the applicable provisions of ERISA. Each Parent Compensation and Benefit Plan that is an "employee pension benefit plan" within the meaning of Section 3(2) of ERISA (a "Parent Pension Plan") and that is intended to be qualified under Section 401(a) of the Code has received favorable determination letter from the IRS, and nothing has occurred, whether by action or failure to act, that would cause the loss of such qualification or that would result in costs to PNM, Parent or any of their Subsidiaries under the Internal Revenue Service's Employee Plans Compliance Resolution System that would reasonably be likely to have a Parent Material Adverse Effect. As of the date hereof, there is no material pending or to the knowledge of Parent or PNM threatened

litigation relating to the PNM Compensation and Benefit Plans. Neither Parent nor any of its Subsidiaries nor, to the knowledge of Parent, any other person has engaged in a transaction with respect to any Parent Compensation and Benefit Plan that, assuming the taxable period of such transaction expired as of the date hereof, would subject Parent or any of its Subsidiaries to a material tax or penalty imposed by either Section 4975 of the Code or Section 502(i) of ERISA. (iii) No liability under Subtitle C or D of Title IV of ERISA has been or is expected to be incurred by Parent, PNM or any of their Subsidiaries with respect to any ongoing, frozen or terminated "single-employer plan", within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or the single-employer plan of any entity which is considered one employer with Parent, PNM or any of their Subsidiaries under Section 4001 of ERISA or Section 414 of the Code (a "Parent ERISA Affiliate"). Parent, PNM and their Subsidiaries have not incurred and do not expect to incur and would not expect to incur any withdrawal liability with respect to a multiemployer plan under Subtitle E of Title IV of ERISA (regardless of whether based on contributions of a Parent ERISA Affiliate) if, as of the date hereof, Parent, PNM or a Parent ERISA Affiliate were to engage in a "complete withdrawal" (as defined in Section 4203 of ERISA) or a "partial withdrawal" (as defined in Section 4205 of ERISA) form such multiemployer plan. No notice of a "reportable event", within the meaning of Section 4043 of ERISA for which the 30-day reporting requirement has not been waived or extended, other than the extension provided by PBGC Reg. Section 4043.66, has been required to be filed for any Parent Pension Plan or by any ERISA Affiliate within the 12-month period ending on the date hereof. (iv) All contributions required to be made under the terms of any Parent Compensation and Benefit Plan as of the date hereof have been timely made or have been reflected on the most recent consolidated balance sheet filed or incorporated by reference in the PNM Reports and all premium payments to the PBGC have been made when due for such plans. Neither any Parent Pension Plan nor any single-employer plan of a Parent ERISA Affiliate has an "accumulated funding deficiency" (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of ERISA and no Parent ERISA Affiliate has an outstanding funding waiver. None of Parent, PNM or any of their Subsidiaries has provided, or is required to provide, security to any Pension Plan or to any single-employer plan of a Parent ERISA Affiliate pursuant to Section 401(a)(29) of the Code. (v) None of Parent, PNM or any of their Subsidiaries have any obligations for, or liabilities with respect to, retiree health and life benefits under any PNM Compensation and Benefit Plan, except for benefits required to be provided under Section 4980B of the Code. (vi) Notwithstanding anything to the contrary contained in this Section 5.2(i), the representations and warranties contained in this Section 5.2(i) shall be deemed to be true and correct unless such failures to be true and correct are reasonably likely to have a Parent Material Adverse Effect. (j) Compliance with Laws. As of the date hereof, the business of PNM and its Subsidiaries, taken as a whole, is not being conducted in violation of any Laws, except for violations that would not be reasonably likely to have, either individually or in the aggregate, a Parent Material Adverse Effect or prevent or materially impair the ability of Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 to consummate the transactions contemplated hereby. As of the date hereof, no investigation or review by any Governmental Entity with respect to Parent or any of its Subsidiaries is pending or to the knowledge of Parent threatened, nor has any Governmental Entity indicated an intention to conduct the same, except for those

the outcome of which would not be reasonably likely to have, either individually or in the aggregate, a Parent Material Adverse Effect or prevent or materially impair the ability of Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 to consummate the transactions contemplated hereby. PNM and its Significant Subsidiaries each has all permits, licenses, franchises, variances, exemptions, orders and other governmental authorizations, consents and approvals from Governmental Entities necessary to conduct its business as presently conducted, except for those the absence of which would not be reasonably likely to have, either individually or in the aggregate, a Parent Material Adverse Effect or prevent or materially impair the ability of Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2 to consummate the transactions contemplated hereby. (k) Takeover Statutes. Assuming the accuracy of the representation contained in Section 5.1(q), no Takeover Statute of the NMBCA or any applicable anti-takeover provision in the certificate of incorporation of PNM, Manzano or Parent or by-laws of PNM, Manzano or Parent is applicable to the Transaction or any of the other transactions contemplated hereby. (l) Environmental Matters. Except for such matters that would not be reasonably likely to cause a Parent Material Adverse Effect: (i) PNM's operations are in compliance with all applicable Environmental Laws; (ii) PNM possesses and maintains in effect all environmental and natural resources permits, licenses, authorizations and approvals required under applicable Environmental Laws with respect to the business of PNM as presently conducted; (iii) PNM has not received any written environmental claim, notice or request for information during the past three years concerning any violation or alleged violation of any applicable Environmental Law or concerning any obligation or liability under any applicable Environmental Law; and (iv) there are no material writs, injunctions, decrees, orders or judgments outstanding, or any actions, suits or proceedings pending relating to compliance by PNM with any environmental permits, licenses, authorizations or approvals required under applicable Environmental Laws or liability of PNM under any applicable Environmental Law. The representations and warranties in this Section 5.1(l) constitute the sole representations and warranties of Parent or PNM with respect to any Environmental Law or Hazardous Substance. As used in this Section 5.2(l), "PNM" shall mean PNM and each of its Subsidiaries. (m) Taxes. Except as would not have a Parent Material Adverse Effect, PNM and each of its Significant Subsidiaries (i) have duly and timely filed (taking into account any extension of time within which to file) all Tax Returns required to be filed by any of them as of the date hereof and all such filed Tax Returns are complete and accurate in all respects; (ii) (A) have timely paid all Taxes that are shown as due on such filed Tax Returns, except with respect to matters contested in good faith and (B) no penalties or charges are due with respect to the late filing of any Tax Return required to be filed by or with respect to any of them on or before the Effective Time; (iii) with respect to any filed Tax Returns, have not waived any statute of limitations with respect to Taxes or agreed to any extension of time with respect to a Tax assessment or deficiency; (iv) as of the date hereof, does not have any deficiency, or any such audits, examinations, investigations or other proceedings in respect of Taxes or Tax matters pending or proposed or threatened in writing; and (v) has not been or is not a party to any Tax sharing agreement or similar arrangement. Except as would not have a Parent Material Adverse Effect when aggregated with the preceding sentence, neither PNM nor any PNM Subsidiary (x) has engaged in any intercompany transaction within the meaning of Treasury Regulation Section 1.1502-13 for which any income or gain remains unrecognized and (y) has constituted a "distributing corporation" in a distribution of stock qualifying for tax-free treatment under Section 355 of the Code (1) in the past 24-month period, or (2)

in a distribution which could otherwise constitute part of a "plan" or "series of related transactions" within the meaning of Section 355(e) of the Code, in each case, excluding any transactions described in Section 355(e)(3) of the Code. (n) Labor and Employment Matters. (i) Labor Relations. Except as would not have a Parent Material Adverse Effect, (A) neither PNM nor any of its Subsidiaries is a party to any collective bargaining agreement or other labor agreement with any labor union, labor organization, employee association or similar organization, nor does PNM or any of its Subsidiaries have knowledge of any such union, labor organization, employee association or similar organization that represents or claims to represent any of PNM's or any of its Subsidiaries' employees or intends to organize any of PNM's or any its Subsidiaries' employees; (B) there is no labor strike, dispute, slowdown, stoppage, lockout or other labor dispute actually pending, nor to the knowledge of PNM, threatened against or affecting PNM or any of its Subsidiaries; (C) to the knowledge of Parent and PNM, neither PNM nor any of its Subsidiaries is engaged in any unfair labor practices as defined in the National Labor Relations Act or other applicable law, ordinance or regulation; nor is there an unfair labor practice charge or complaint against PNM or any of its Subsidiaries pending or, to the knowledge of PNM, threatened before the National Labor Relations Board or any similar state agency; and (D) there is no grievance pending, nor to the knowledge of PNM, is there any grievance threatened arising out of any collective bargaining agreement or other grievance procedure. (ii) Employment. Except as would not have Parent Material Adverse Effect, (A) neither PNM nor any of its Subsidiaries is in material violation of any applicable laws respecting employment and employment practices, terms and conditions of employment, wages, hours of work and occupational safety and health, nor have they ever been; (B) to the knowledge of the Parent and PNM, there are no charges with respect to or relating to PNM or any of its Subsidiaries pending before the Equal Employment Opportunity Commission or any other agency responsible for the prevention of unlawful employment practices; (C) to the knowledge of the Parent and PNM, neither PNM nor any of its Subsidiaries received notice of the intent of any federal, state or local agency responsible for the enforcement of labor or employment laws to conduct an investigation with respect to or relating to PNM or any of its Subsidiaries and no such investigation is in progress; and (D) to the knowledge of the Parent and PNM, there are no complaints, lawsuits or other proceedings pending or threatened in any forum by or on behalf of any present or former employee of PNM or any of its Subsidiaries, any applicant for employment or classes of the foregoing alleging breach of any express or implied contract for employment, any law or regulation governing employment or the termination thereof or other discriminatory, wrongful or tortuous conduct in connection with the employment relationship. (iii) WARN Act. PNM is presently in compliance with its notification obligations with respect to PNM's employees pursuant to the Worker Adjustment and Retraining Notification (WARN) Act and will conduct any plant closing or mass layoff prior to the date of Closing in accordance with WARN. (o) Intellectual Property. (i) PNM and its Significant Subsidiaries own, or are licensed or otherwise possess sufficient legally enforceable rights to use, all patents, trademarks, trade names, service marks, copyrights, technology, know-how, computer software programs or applications, databases and tangible or intangible proprietary information or materials that are currently used in its and its Subsidiaries' businesses (collectively, "PNM Intellectual Property Rights"), except for any such failures to own, be licensed or possess that, individually or in the aggregate, are not reasonably likely to have a Parent Material Adverse Effect.

(ii) Except as disclosed in the PNM Reports filed prior to the date hereof, and except for such matters that, individually or in the aggregate, are not reasonably likely to have a Parent Material Adverse Effect, (i) to the knowledge of Parent, the use of the PNM Intellectual Property Rights by PNM or its Significant Subsidiaries does not conflict with, infringe upon, violate or interfere with or constitute an appropriation of any right, title, interest or goodwill, including, without limitation, any intellectual property right, patent, trademark, trade name, service mark, copyright of any other Person and (ii) there have been no claims made and neither the PNM nor any of its Significant Subsidiaries has received written notice of any claim or otherwise knows that any PNM Intellectual Property Right is invalid, or conflicts with the asserted right of any other Person. (p) Vote Required. The approval of the Second Merger by two-thirds of the holders of Manzano Common Stock or PNM Common Stock, as the case may be, (the "Parent Requisite Vote") is the only vote of the holders of any class or series of the capital stock of Parent, Manzano or PNM required to approve this Agreement and the transactions contemplated hereby. (q) Ownership of Company Common Stock. None of Parent, Manzano, PNM, Merger Sub-1 Merger Sub-2 or any of their respective Subsidiaries beneficially owns any Company Common Stock. (r) Regulation as to Utility. None of Merger Sub-1, Merger Sub-2 or Parent is a "public utility company," or a "holding company" under the 1935 Act. None of Merger Sub-1, Merger Sub-2 or Parent is subject to regulation as a public utility company in any state or by the FERC. PNM is a public utility company subject to regulation as such in the State of New Mexico and by the FERC. At the Manzano Transition Date, Manzano will be a "holding company" exempt under Section 3(a)(1) pursuant to Rule 2 from all provisions of the 1935 Act except Section 9(a)(2) thereof.

PNM has received the opinion of JP Morgan dated as of the date hereof to the effect that, as of such date, the PNM ownership percentage is fair from a financial point of view to the holders of PNM Common Stock. (u) Nuclear Plant Operation. To the knowledge of PNM, the operations of the Palo Verde Nuclear Generating Station are being conducted in compliance with applicable health, safety, regulatory and other legal requirements, except where the failure to be in compliance in the aggregate does not, and insofar as can reasonably be foreseen, would not have a Parent Material Adverse Effect.

With respect to each Stock Plan that remains in effect following the Effective Time and each award granted prior to the Effective Time pursuant to a Stock Plan that is to be settled in shares of Company Common Stock (a "Stock Award") which Stock Award remains outstanding following the Effective Time, the Company and Parent shall take all corporate action necessary or appropriate to (i) provide for the issuance or purchase in the open market of Parent Common Stock rather than Company Common Stock pursuant thereto, (ii) obtain shareholder approval with respect to such Stock Plans to the extent such approval is required for purposes of the Code or other applicable law, (iii) reserve for issuance under such Stock Plans or otherwise provide a sufficient number of shares of Parent Common Stock for delivery upon payment of benefits, grant of awards or exercise of options under such Stock Plans or Stock Award and (iv) as soon as practicable after the Effective Time, file registration statements on Form S-8 or amendments on such forms to the Form S-4 Registration Statement, as the case may be (or any successor or other appropriate forms), with respect to the shares of Parent Common Stock subject to such Stock Plans or Stock Award to the extent such registration statement is required under applicable law, and Parent shall use its best efforts to maintain the effectiveness of such registration statements (and maintain the current status of the prospectuses contained therein) for so long as such benefits and grants remain payable and such options remain outstanding. With respect to those individuals who

subsequent to the Merger will be subject to the reporting requirements under Section 16(a) of the Exchange Act, the Surviving Corporation shall administer the Stock Plans after the Effective Time, where applicable, in a manner that complies with Rule 16b-3 promulgated under the Exchange Act. (b) Contributions to Rabbi Trusts. Prior to the Effective Time, the Company shall contribute to the rabbi trusts maintained or to be established by the Company and its Subsidiaries for (i) the Executive Stock Compensation Program under the Long Term Incentive and Share Award Plan, (ii) the Restricted Share Unit Program under the Long Term Incentive and Share Award Plan, and (iii) the Executive Salary Continuation Plan, the amount of cash or shares of Company Common Stock that it reasonably believes will be required to satisfy outstanding awards or other obligations under such plans (other than any such awards that will be converted to Merger Consideration that is immediately distributed to the holder thereof), and at or prior to the end of each year commencing with the year in which the Closing occurs, Parent shall contribute or cause to be contributed to the rabbi trust any amount of cash or securities required to make up any shortfall in earnings and any additional amounts to keep all benefits and estimated expenses fully funded. (c) Employee Benefits. Parent agrees that, during the period commencing at the Effective Time and ending on the second anniversary thereof, the non-union employees of the Company and its Subsidiaries who continue to be employees of the Surviving Corporation, Parent or their respective Subsidiaries (the "Non-Union Employees") will continue to be provided with benefits under employee benefit plans that are no less favorable in the aggregate than those currently provided by the Company and its Subsidiaries to such employees. Following the Effective Time, Parent shall cause service by Non-Union Employees of the Company and its Subsidiaries (and any predecessor entities) to be taken into account for all purposes (including, without limitation, eligibility to participate, eligibility to commence benefits, vesting, benefit accrual and severance) under the Compensation and Benefit Plans or any other benefit plans of Parent or its Subsidiaries in which such employees participate. From and after the Effective Time, Parent shall (i) cause to be waived any pre-existing condition limitations under benefit plans, policies or practices of Parent or its Subsidiaries in which employees of the Company or its Subsidiaries participate and (ii) cause to be credited any deductibles and out-of-pocket expenses incurred by such employees and their beneficiaries and dependents during the portion of the calendar year prior to participation in the benefit plans provided by Parent and its Subsidiaries. Parent shall, and shall cause the Surviving Corporation to, honor all employee benefit obligations to current and former employees and directors under the Compensation and Benefit Plans and to honor all collective bargaining agreements or other labor agreements in effect at the Effective Time. Parent shall cause the Surviving Corporation to assume in writing the rights and obligations under the employment agreements and change of control agreements to which the Company is a party at the Effective Time as required by such agreements; provided, however, that the foregoing shall not prevent Parent or the Surviving Corporation from enforcing such employment agreements and change of control agreements in accordance with their terms, including, without limitation, any reserved right to amend, modify, suspend, revoke or terminate any such employment agreements and change of control agreements. Parent acknowledges that the transactions contemplated by this Agreement meet the definition of, and shall constitute, a "change in control" under each Compensation and Benefit Plan listed in Section 7.9 of the Company Disclosure Letter. (d) Employees. It is the present intention of Parent and the Company that following the

Effective Time, there will be no involuntary reductions in workforce at the Surviving Corporation or its Subsidiaries, and that Parent, the Surviving Corporation and their respective Subsidiaries will continue Parent's and the Company's present strategy of achieving workforce reductions through attrition or other voluntary means; provided, however, that if any reductions in workforce in respect of employees of Parent and its Subsidiaries, including the Surviving Corporation and its Subsidiaries, become necessary, they shall be made on a fair and equitable basis, in light of the circumstances and the objectives to be achieved, giving consideration to previous work history, job experience, qualifications, and business needs without regard to whether employment prior to the Effective Time was with the Company or its Subsidiaries or Parent or its Subsidiaries, and any employees whose employment is terminated or jobs are eliminated by Parent, the Surviving Corporation or any of their respective Subsidiaries shall be entitled to participate on a fair and equitable basis in the job opportunity and employment placement programs offered by Parent, the Surviving Corporation or any of their respective Subsidiaries. Any workforce reductions carried out following the Effective Time by Parent or the Surviving Corporation and their respective Subsidiaries shall be done in accordance with all applicable collective bargaining agreements, and all Laws and regulations governing the employment relationship and termination thereof including, without limitation, the Worker Adjustment and Retraining Notification Act and regulations promulgated thereunder, and any comparable state or local law. 7.10. Board of Directors; Corporate Headquarters and Community Involvement. (a) Election to Parent's Board of Directors. At the Effective Time, Parent shall take such action as may be necessary to cause two individuals selected by Parent from a pool of nominees designated by the Company, including members of the Board of Directors of the Company, to be appointed to the Board of Directors of Parent with each such designee serving in a different class on the Parent Board of Directors. The directors designated by the Company shall comply with the Parent's criteria for membership on its Board of Directors as in effect for PNM as of the date hereof and set forth in Section 7.10 of the Parent Disclosure Schedule. Each of the directors designated by the Company shall be appointed to serve on a committee of the Parent Board of Directors. The rights set forth in this Section 7.10 are separate from and in addition to any rights Westar shall have to designate members of the Board of Directors of Parent pursuant to the terms of the Stockholder Agreement between Westar and Parent to be entered into as of the Effective Time. (b) Regional Headquarters. Following the Effective Time, the Surviving Corporation shall maintain its regional headquarters in Topeka, Kansas. (c) Community Involvement. Parent acknowledges that after the Effective Time, it intends to provide charitable contributions and community support within the service areas of the Company and its Subsidiaries at levels consistent with past practice. 7.11. Dividends. The Company and Parent shall coordinate with each other the declaration, setting of record dates and payment dates of dividends on shares of their respective common stock so that holders of shares of Company Common Stock do not receive dividends on both shares of Company Common Stock and Parent Common Stock received in the Merger in respect of any single calendar quarter or fail to receive a dividend on either shares of Company Common Stock or Parent Common Stock received in the Merger in respect of any single calendar quarter. 7.12. Indemnification; Directors' and Officers' Insurance. (a) Parent shall indemnify and hold harmless, to the fullest extent permitted under applicable law and as required pursuant to the existing indemnity agreements of the Company (and Parent shall also advance expenses as

incurred to the fullest extent permitted under applicable law and as required pursuant to the existing indemnity agreements of the Company provided the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification), each present and former director, officer and employee of the Company and its Subsidiaries (collectively, the "Indemnified Parties") against any costs or expenses (including attorneys' fees and expenses), judgments, fines, losses, claims, damages or liabilities (collectively, "Costs") incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the Effective Time, including the transactions contemplated hereby. In the event any claim or claims are asserted or made within six years after the Effective Time, all rights to indemnification in respect of any such claim or claims shall continue until final disposition of any and all such claims. (b) Any Indemnified Party wishing to claim indemnification under paragraph (a) of this Section 7.12, upon receiving written notification of any such claim, action, suit, proceeding or investigation, shall promptly notify the Surviving Corporation thereof, but the failure to so notify shall not relieve the Surviving Corporation of any liability it may have to such Indemnified Party if such failure does not materially and irreversibly prejudice Parent. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) Parent shall pay the fees and expenses of counsel selected by the Indemnified Party, which counsel shall be reasonably satisfactory to Parent, promptly after statements therefor are received, and otherwise advance to such Indemnified Party upon request reimbursement of documented expenses reasonably incurred, (ii) Parent will cooperate in the defense of any such matter, and (iii) any determination required to be made with respect to whether an Indemnified Party's conduct complies with the standards set forth under applicable Law shall be made by independent counsel mutually acceptable to Parent and the Indemnified Party; provided, however, that (A) Parent shall be obligated pursuant to this paragraph (b) to pay for only one firm of counsel for all Indemnified Parties in any jurisdiction, except to the extent there is, in the opinion of counsel to an Indemnified Party, under applicable standards of professional conduct, a conflict on any significant issue between the positions of such Indemnified Party and any other Indemnified Party or Indemnified Parties, in which case each Indemnified Party with a conflicting position on a significant issue shall be entitled to retain separate counsel mutually satisfactory to Parent and such Indemnified Party, (B) the Indemnified Parties shall cooperate in the defense of any such matter and (C) Parent shall not be liable for any settlement effected without its prior written consent (which consent may not be unreasonably withheld or delayed). (c) The Surviving Corporation shall maintain the Company's existing officers' and directors' liability insurance ("D&O Insurance") for a period of six years after the Effective Time so long as the annual premium therefor is not in excess of 200% of the last annual premium paid prior to the date hereof (the "Current Premium"); provided, however, if the existing D&O Insurance is terminated or cancelled during such six-year period, the Surviving Corporation shall use its best efforts to obtain as much D&O Insurance as can be obtained for the remainder of such period for a premium not in excess (on an annualized basis) of 200% of the Current Premium and shall agree to indemnify the directors and officers for any Costs not covered by such D&O Insurance; and (iii) if the annual premiums for the existing D&O Insurance exceed 200% of the Current Premium, the Surviving Corporation shall obtain as much D&O Insurance as can be obtained for the remainder of such period for a premium not in excess (on an annualized basis) of 200% of the Current Premium. (d) If Parent or the Surviving Corporation or any of its successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Surviving Corporation shall assume all of the obligations set forth in this Section 7.12.

(e) The provisions of this Section 7.12 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives. 7.13. Expenses. Subject to Sections 9.5(b) through (e), whether or not the Mergers are consummated, all costs and expenses incurred in connection with the Mergers and the other transactions contemplated hereby shall be paid by the party incurring such expense, except that each of the Company and PNM shall bear and pay one-half of the costs and expenses incurred in connection with the filing, printing and mailing of the S-4 Registration Statement and the Prospectus/Proxy Registration Statement (including SEC filing fees). 7.14. Takeover Statute. If any Takeover Statute is or may become applicable to the Mergers or the other transactions contemplated hereby, each of Parent, Manzano, PNM, Merger Sub-1 Merger Sub-2 and the Company and their respective Board of Directors shall grant such approvals and take such actions as are necessary so that such transactions may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of such statute or regulation on such transactions. 7.15. Manzano Vote. Parent and Manzano shall vote (or consent with respect to) or cause to be voted (or a consent to be given with respect to) any shares of Company Common Stock and any shares of common stock of Merger Sub-1 and Merger Sub-2 beneficially owned by it or any of its Affiliates or with respect to which it or any of its Affiliates has the power (by agreement, proxy or otherwise) to cause to be voted (or to provide a consent), in favor of the approval of this Agreement and the transactions contemplated hereby at any meeting of shareholders of the Company, Merger Sub-1 or Merger Sub-2, respectively, at which this Agreement shall be submitted for approval and at all adjournments or postponements thereof (or, if applicable, by any action of shareholders of either the Company, Merger Sub-1 or Merger Sub-2 by consent in lieu of a meeting). 7.16. Agreements Relating to the Split-Off. The terms of the Split-Off Agreements may be amended by the Company and Westar; provided however, that Parent's consent, which shall not be unreasonably withheld, shall be required in connection with any revision to the terms of the Split-Off Agreements in the forms attached hereto as Exhibit A that would reasonably be expected to be adverse in any manner to the Company or to Parent. 7.17. Redemption of Preferred Shares. Prior to the Effective Time, the Board of Directors of the Company shall call for redemption all outstanding Preferred Shares (not including the Convertible Preference Shares) at a redemption price equal to the amount set forth in the restated articles of incorporation of the Company, together with all dividends accrued and unpaid to the date of such redemption and take all other required action so that all Preferred Shares shall be redeemed and no such Preferred Shares shall be deemed to be outstanding at the Effective Time or entitled to vote on the approval of this Agreement and the transactions contemplated hereby. The parties agree to cooperate in connection with registering Parent as a "holding company" under Section 5 of the 1935 Act to use the provisions of subparagraph (iv) of subdivision (c) of paragraph 6 of section A of Article IV of the restated articles of incorporation of the Company as a means of obviating the need to seek approval of this Agreement and the transactions contemplated hereby by the holders of Preferred Shares as a separate class, in which case the outstanding Preferred Shares shall not be called for redemption and shall remain outstanding notwithstanding the Merger.

7.18. Conveyance Taxes. The Company, Parent, PNM and Manzano shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp Taxes, any transfer, recording, registration and other fees, and any similar Taxes which become payable in connection with the transactions contemplated by this Agreement ("Transaction Taxes") that are required or permitted to be paid on or before the Effective Time. The Company shall pay, without deduction or withholding (except where such deduction or withholding is required by applicable law) from any amount payable to the holders of any shares of the Company Common Stock, any such Transaction Taxes which become payable in connection with the Split-Off and Merger, on behalf of the shareholders of the Company. Manzano, or PNM, as the case may be, shall pay, without deduction or withholding (except where such deduction or withholding is required by applicable law) from any amount payable to the holders of any shares of Manzano Common Stock or PNM Common Stock, any such Transfer Taxes which become payable in connection with the Transaction. 7.19. Transition Steering Team. As soon as reasonably practicable after the date hereof, PNM and the Company shall create a special transition steering team (the "Transition Steering Team"), with representation from PNM and the Company, that will develop recommendations concerning the future structure and operations of the Surviving Corporation after the Effective Time, subject to applicable law. The members of the Transition Steering Team shall be appointed by the Chief Executive Officers of PNM and the Company. The functions of the Transition Steering Team shall include (i) to direct the exchange of information and documents between the parties and their subsidiaries as contemplated by Section 7.1, and (ii) the development of regulatory plans and proposals, corporate organizational and management plans, workforce combination proposals, and such other matters as they deem appropriate. 7.20. Termination of Tax Sharing Agreements. At the effective time of the Split-Off, the Company shall cause the Tax sharing agreement with Protection One, Inc. and all other tax sharing agreements and arrangements (other than the Disaffiliation Agreement) to be terminated or no longer in effect with respect to periods following the date of the Split-Off as between any member of the Western Group and its Affiliates (as those terms are defined in the Tax Disaffiliation Agreement) on the one hand and any member of the Westar Group and its Affiliates (as those terms are defined in the Tax Disaffiliation Agreement) on the other hand. 7.21. Tax Disaffiliation Agreement. At the Effective Time, Parent shall succeed to the rights and obligations of the Company under the Tax Disaffiliation Agreement and shall perform all agreements and covenants contained therein. 7.22. Shared Services Agreement. Effective upon the Closing, the Company or such other affiliate of the Company as shall be designated by Parent subject to Westar's approval shall enter into a Shared Services Agreement in form and substance reasonably satisfactory to each party and satisfying all requirements of the 1935 Act, pursuant to which the Company shall provide services to Westar on the terms and conditions specified in Exhibit B to the Allocation and Separation Agreement. Effective as of the Closing Date, the Company will assign the Service Agreement between the Company and Protection One, Inc., dated April 1, 1999, as amended, to Westar. 7.23. Interim Reporting. No later than the tenth Business Day of each calendar month through the Cut-Off Date, the Company will deliver a statement with respect to the

immediately preceding calendar month, of (i) Additional Cash paid to the Company (including information as to the source) during such month, (ii) the application of such Additional Cash, and (iii) the option selected by Westar pursuant to Section 3.2(a)(i), such statement also to include a summary of cumulative amounts and any changes in amounts since the date hereof. 7.24. Possible Exchange. The parties recognize that it would be beneficial for Parent if, in lieu of the conversion of the Convertible Preference Shares into the Parent Convertible Shares pursuant to Section 3.2(b)(iv) hereof (the "Conversion"), the Convertible Preference Shares were instead exchanged (an "Exchange") for a principal amount of 7.5% subordinated debt instruments of Parent equal to the aggregate liquidation preference of the Convertible Preference Shares which debt instruments ("Parent Convertible Debt") would be (i) convertible into shares of Parent Common Stock at the same conversion ratio as the Convertible Preference Shares, (ii) otherwise substantially in the form of the Company's 7-7/8% Cumulative Quarterly Income Preferred Shares, Series A, and (iii) redeemable at the option of Parent at par plus accrued interest on the same date on which the Parent Convertible Shares would have been first redeemable at the option of Parent. Accordingly, if, prior to satisfaction of the conditions contained in Article VIII hereof, Parent proposes that an Exchange occur and such Exchange would (i) not delay the Effective Time and (ii) otherwise preserves for Westar the economic and tax benefits of ownership of Parent Convertible Shares that otherwise would have been received upon conversion of the Convertible Preference Shares including, but not limited to, the payment to Westar of cash in an amount that reasonably compensates Westar for the reasonably estimated additional Tax payments, if any, resulting from the Proposed Exchange (taking into account, among other things, the amount (as reasonably projected on the Effective Date) of (x) Westar's additional tax liability from the Exchange being taxable and Westar subsequently receiving interest instead of dividends until the date that the Parent Convertible Debt could have first been redeemed by Parent (the "First Redemption Date") and (y) the utilization of or loss of any current or future tax benefits of the Westar Group that could be used to offset tax liability of any member of the Westar Group in any Tax period through the end of the Tax period which includes the First Redemption Date), then the parties shall make a good faith effort to effect an Exchange instead of a Conversion by means of mutually agreed customary documentation that so preserves such benefits; provided that if the Company Requisite Vote or the Parent Requisite Vote has already been obtained, such Exchange does not require any additional approval of the shareholders of the Company under the KGCC or other applicable law or the shareholders of PNM or Parent under the NMBCA or other applicable law. In the event that the parties adopt an Exchange, the Agreement shall be revised to reflect such transaction as determined necessary by the parties hereto and prior to effecting any such Exchange, all material third party and Governmental Authority declarations, filings, registrations, notices, authorizations, consents or approvals necessary for the effectuation of such Exchange shall have been obtained and all other conditions to the parties' obligations to consummate the Transaction and other transactions contemplated hereby, as applied to such Exchange, shall have been satisfied or waived. Article VIII. Conditions 8.1. Conditions to Each Party's Obligation to Effect the Transaction. The respective obligation of each party to effect the Mergers is subject to the satisfaction or waiver at or prior to the Effective Time of each of the following conditions: (a) Shareholder Approval. The Company Requisite Vote and the Parent Requisite Vote shall have been obtained. This Agreement shall have been approved by the sole shareholder of Merger Sub-1 and Merger Sub-2.

The Parent Required Statutory Approvals and the Company Required Statutory Approvals shall have been obtained at or prior to the Effective Time, such approvals shall have become Final Orders (as hereinafter defined), and no such Final Order shall impose terms or conditions that would have, or would be reasonably likely to have a material adverse effect on the financial condition, business, assets or results of operations of Parent, Manzano, PNM and the Company (together with their respective Subsidiaries) taken as a whole; it being understood that the effect of any law, regulation, ruling, order or decree referred to in Sections 8.2(f) and 8.3(e) shall not be taken into account in making such determination. A "Final Order" means action (including the approval of transfer, assignment or modification of Environmental Permits) by the relevant regulatory authority that has not been reversed, stayed, enjoined, set aside, annulled or suspended, with respect to which any waiting period prescribed by law before the transactions contemplated hereby may be consummated has expired, and as to which all conditions to the consummation of such transactions prescribed by law, regulation or order have been satisfied. (e) Injunction. No court or Governmental Entity of competent jurisdiction shall have enacted, issued, promulgated, enforced or entered any statute, law, ordinance, rule, regulation, judgment, decree, injunction or other order that is in effect and permanently enjoins or otherwise prohibits consummation of the Mergers or the other transactions contemplated hereby (collectively, an "Order"). (f) S-4. The S-4 Registration Statement shall have become effective under the Securities Act. No stop order suspending the effectiveness of the S-4 Registration Statement shall have been issued, and no proceedings for that purpose shall have been initiated or be threatened, by the SEC. (g) Split-Off.

Mergers are also subject to the satisfaction or waiver by Parent at or prior to the Effective Time of the following conditions: (a) Representations and Warranties. The representations and warranties of the Company set forth in this Agreement which are not modified by the words "Material Adverse Effect" shall be true and correct as of the Closing Date as though made on and as of the Closing Date, except for failures to be true and correct that individually or in the aggregate would not reasonably be likely to have a Company Material Adverse Effect (except to the extent any such representation or warranty expressly speaks as of an earlier date, which representations and warranties shall be true and correct as of such date in the same manner as specified above), and the representations and warranties of the Company set forth in this Agreement which are modified by the words "Material Adverse Effect" shall be true and correct as of the Closing Date as though made on and as of the Closing Date (except to the extent any such representation or warranty expressly speaks as of an earlier date, which representations and warranties shall be true and correct as of such date in the same manner as specified above), and Parent shall have received a certificate signed on behalf of the Company by an executive officer of the Company to such effect.

In rendering such opinion, Winthrop, Stimson, Putnam & Roberts may require and rely upon representations reasonably satisfactory to Winthrop, Stimson, Putnam & Roberts contained in certificates of officers of the Company, Westar, Parent, Manzano, PNM, Merger Sub-1 and Merger Sub-2. (d) Consents Under Agreements. The Company shall have obtained the consent or approval of each person whose consent or approval shall be required under any material Company Contract except for such consents or approvals the failure of which to obtain would not be reasonably likely to result in a material adverse effect on Parent and the Company (together with the Subsidiaries of Parent and the Company), taken as a whole. (e) Affiliates Letters. Parent shall have received an Affiliates Letter from each person identified as an affiliate of the Company pursuant to Section 7.6. (f) No Adverse Regulatory Change. Since the date of this Agreement, no law, regulation, ruling, order or decree (or new interpretation of any of the foregoing) affecting the Company or Kansas Gas and Electric Company shall have been adopted, amended or issued that, individually or in the aggregate, would have a material adverse effect on the financial condition, business, assets or results of operations of Parent, Manzano, PNM and the Company (together with their respective Subsidiaries) taken as a whole. In determining whether this condition has been satisfied, Parent (i)

shall also take into account the effects of any ruling, order or decree by any Governmental Entity issued between the date hereof and the Closing Date on the electric rates and charges of the Company and Kansas Gas and Electric Company or on the revenue potential of the Company and Kansas Gas and Electric Company as existing on the date of this Agreement, and (ii) shall not take into account the Parent Required Statutory Approvals and the Company Required Statutory Approvals. 8.3. Conditions to Obligation of the Company. The obligation of the Company to effect the Merger is also subject to the satisfaction or waiver by the Company at or prior to the Effective Time of the following conditions: (a) Representations and Warranties. The representations and warranties of Parent, PNM, Manzano, Merger Sub-1 and Merger Sub-2 set forth in this Agreement which are not modified by the words "Material Adverse Effect" shall be true and correct as of the Closing Date as though made on and as of the Closing Date, except for failures to be true and correct that individually or in the aggregate would not reasonably be likely to have a Parent Material Adverse Effect (except to the extent any such representation or warranty expressly speaks as of an earlier date, which representations and warranties shall be true and correct as of such date in the same manner as specified above) and the representations and warranties of Parent, PNM, Manzano, Merger Sub-1 and Merger Sub-2 set forth in this Agreement which are modified by the words "Material Adverse Effect" shall be true and correct as of the Closing Date as though made on and as of the Closing Date (except to the extent any such representation or warranty expressly speaks as of an earlier date, which representations and warranties shall be true and correct as of such date in the same manner as specified above), and the Company shall have received a certificate signed on behalf of Parent by an executive officer of Parent to such effect.

(c) Tax Opinion. The Company shall have received an opinion from LeBoeuf, Lamb, Greene & MacRae L.L.P., tax counsel to the Company, in form and substance reasonably satisfactory to the Company, dated as of the Closing Date, substantially to the effect that (i) the Split-Off will be treated as a taxable exchange of the Split-Off Portion of the Company Common Stock for shares of Westar Common Stock and (ii) the Mergers, taken together, will be treated as a transaction described in Section 351 of the Code or the Merger will be treated as a transaction described in Section 368(a) of the Code; provided, however, that the condition set forth in clause (i) above shall also be satisfied to the extent the Company receives a private letter ruling from the Internal Revenue Service, in form and substance reasonably satisfactory to the Company, substantially to the same effect as the opinion described in clause (i) above. In rendering such opinion LeBoeuf, Lamb, Greene & MacRae, L.L.P. may require and rely upon representations reasonably satisfactory to LeBoeuf, Lamb, Greene & MacRae, L.L.P. contained in certificates of officers of the Company, Westar, Parent, Manzano, PNM, Merger Sub-1 or Merger Sub-2. (d) Consents Under Agreements. Parent shall have obtained the consent or approval of each Person whose consent or approval shall be required under any material Parent Contract except for such consents or approvals the failure of which to obtain would not be reasonably likely to result in a material adverse effect on Parent and the

Company (together with the Subsidiaries of Parent and the Company) taken as a whole. (e) No Adverse Regulatory Change. Since the date of this Agreement, no law, regulation, ruling, order or decree (or new interpretation of any of the foregoing) affecting the Parent shall have been adopted, amended or issued that, individually or in the aggregate, would have a material adverse effect on the financial condition, business, assets or results of operations of Parent, Manzano, PNM and the Company (together with their respective Subsidiaries) taken as a whole. In determining whether this condition has been satisfied, the Company (i) shall also take into account the effects of any ruling, order or decree by any Governmental Entity issued between the date hereof and the Closing Date on the rates and charges of PNM (or any successor regulated as to rates by the NMPRC or the FERC) or on the revenue potential of the Company and PNM (or any successor regulated as to rates by the NMPRC or the FERC) as existing on the date of this Agreement, and (ii) shall not take into account the Parent Required Statutory Approvals and the Company Required Statutory Approvals.

In the event that an Acquisition Proposal shall have been made to the Company after the date hereof or any person (other than PNM or any of its Affiliates) shall have publicly announced after the date hereof an intention (whether or not conditional) to make an Acquisition Proposal with respect to the Company and thereafter this Agreement is terminated (i) by either PNM or the Company pursuant to Section 9.2(b) (following the failure to obtain the Company Requisite Vote at a time when such Acquisition Proposal remains outstanding) or (ii) by PNM pursuant to Section 9.4(c) (following withdrawal or failure to affirm the recommendation by the Company's Board of Directors), pay PNM a termination fee (as liquidated damages) of $35 million by wire transfer of same day funds to an account previously designated by PNM to the Company in writing. (c) In the event that this Agreement is terminated by PNM pursuant to Section 9.4(a), then PNM shall promptly, but in no event later than two days after the date of such termination, pay the Company a termination fee (as liquidated damages) of $35 million by wire transfer of same day funds to an account previously designated in writing by the Company to PNM.

that an Acquisition Proposal shall have been made to PNM or Manzano after the date hereof or any person (other than the Company or any of its Affiliates) shall have publicly announced after the date hereof an intention (whether or not conditional) to make an Acquisition Proposal with respect to PNM and thereafter this Agreement is terminated (i) by either the Company or PNM pursuant to Section 9.2(b) (following the failure to obtain the Parent Requisite Vote at a time when such Acquisition Proposal remains outstanding) or (ii) or by the Company pursuant to Section 9.3(c) (following withdrawal or failure to affirm the recommendation by Board of Directors of PNM or Manzano), pay the Company a termination fee (as liquidated damages) of $35 million, by wire transfer of same day funds to an account previously designated by the Company to PNM in writing. (d) In the event that this Agreement is terminated by either PNM or the Company pursuant to Section 9.2(b) as a result of failure to obtain the Company Requisite Vote and at the time of the related meeting of Company Shareholders no Acquisition Proposal for the Company is outstanding, then the Company shall promptly, but in no event later than two days after the date of such termination, pay to PNM by wire transfer of same day funds to an account previously designated by PNM to the Company in writing an amount equal to $17.5 million.

(f) The parties acknowledge that the agreements contained in Sections 9.5(b) through (e) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements the other party would not have entered into this Agreement; accordingly, if any party fails to promptly pay any amounts due pursuant to Sections 9.5(b) through (e) and in order to obtain such payment the other party commences a suit which results in a judgement against the defaulting party for payment of all or a portion of a termination fee, the defaulting party shall pay to the other party its costs and expenses (including its reasonable attorneys' fees) incurred in connection with such suit, together with interest from the date of termination of this Agreement on the amounts owed at the prime rate of Citibank, N.A. in effect from time to time during such period.

This Agreement shall not be assignable by operation of law or otherwise; provided, however, that Parent may designate, by written notice to the Company, another wholly owned direct or indirect subsidiary to be a constituent corporation in lieu of Merger Sub-1 or Merger Sub-2, so long as such designation would not reasonably be expected to (i) impose any material delay in the obtaining of, or significantly increase the risk of not obtaining any Parent Required Statutory Approval or Company Required Statutory Approval or the expiration or termination of any applicable waiting period, (ii) significantly increase the risk of any Governmental Entity entering an order prohibiting the consummation of the Mergers, (iii) significantly increase the risk of not being able to remove any such order on appeal or otherwise or (iv) materially delay the consummation of the Mergers. If the requirements of the previous sentence are met and Parent wishes to designate another wholly owned direct or indirect subsidiary to be a constituent corporation in lieu of Merger Sub-1 or Merger Sub-2, then, all references herein to Merger Sub-1 or Merger Sub-2, as the case may be, shall be deemed references to such other subsidiary, except that all representations and warranties made herein with respect to Merger Sub-1 or Merger Sub-2, as the case may be, as of the date of this Agreement shall be deemed representations and warranties made with respect to such other subsidiary as of the date of such designation.
