PUBLIC SERVICE COMPANY OF NEW MEXICO By __________________________ Title: CANADIAN IMPERIAL BANK OF COMMERCE, NEW YORK AGENCY By __________________________ Title: By __________________________ Title: EXHIBIT A [FORM OF OPINION OF KELEHER & MCLEOD, P.A., SPECIAL NEW MEXICO COUNSEL TO THE COMPANY] July 1, 1994 Canadian Imperial Bank of Commerce New York Agency 425 Lexington Avenue New York, New York 10017 Pollution Control Revenue Refunding Bonds, 1992 Series A (Public Service Company of New Mexico Palo Verde Project) (the "Bonds") Ladies and Gentlemen: As New Mexico counsel to Public Service Company of New Mexico, a New Mexico corporation (the "Company"), and in connection with the issuance of the Bonds in 1992, we are familiar with the corporate records of the Company, including (i) its Restated Articles of Incorporation and by-laws, as amended to date, and (ii) the corporate proceedings of the Board of Directors of the Company. We have examined the following: (a) the Reimbursement Agreement, dated as of November 1, 1992 (as amended and modified from time to time, the "Reimbursement Agreement"), and the Amendment No. 1 thereto, dated as of July 1, 1994 (the "Amendment"), between the Company and Canadian Imperial Bank of Commerce, acting through its New York Agency (the "Bank"); and (b) the Pledge Agreement, dated as of November 1, 1992, among the Company, First National Bank in Albuquerque, as Collateral Agent, and the Bank. The above-referenced documents are collectively referred to as the "Subject Documents". Capitalized terms not otherwise defined herein have the meanings specified in the Reimbursement Agreement as amended by the Amendment. In this connection, we have also examined originals or photocopies or certified copies of such documents, corporate records, agreements and other instruments, and certificates of public officials and officers of the Company, as we have deemed necessary as a basis for the opinions hereinafter expressed. In such examination, except with respect to instruments executed by the Company or any officer thereof, we have assumed the genuineness of all signatures (other than those of officers of the Company), the authenticity of all instruments submitted to us as originals and the conformity to authentic original instruments of all copies submitted to us as certified copies or photocopies. As to questions of fact material to our opinion, we have, when relevant facts were not independently established, relied upon certifications by officers of the Company. Based upon the foregoing and having regard to legal considerations we deem relevant, we are of the opinion that: (1) The execution, delivery and performance by the Company of the Amendment are within the Company's corporate powers, have been duly authorized by all necessary corporate action, do not contravene (a) the Company's Organic Documents or (b) any law, rule or regulation, or, to the best of our knowledge, any Contractual Obligation, court order or consent decree binding on or affecting the Company or any of its Designated Subsidiaries, and do not result in or require the creation of any lien, security interest or other charge or encumbrance upon or with respect to any of their respective properties, except as contemplated by the Pledge Agreement. (2) No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority is required for the due execution and delivery by the Company of the Amendment, and for the performance by the Company of the Reimbursement Agreement as amended by the Amendment or the Pledge Agreement, other than New Mexico Public Utility Commission ("NMPUC") approvals relating to collateralization and refunding, each of which has been duly obtained and is in full force and effect, and an informational compliance filing relating to the Amendment which will be made with the NMPUC. (3) (a) The governing law clauses of the Amendment, the Reimbursement Agreement as amended by the Amendment and the Pledge Agreement, subjecting them to the law of the State of New York, are valid under the law of the State of New Mexico to the extent that they relate to substantive law and not to procedural or remedial matters. (b) Under the law of the State of New Mexico, the substantive law of the State of New York will be applied to agreements such as the Amendment, the Reimbursement Agreement as amended by the Amendment and the Pledge Agreement, except to the extent that any term of either such agreement or any provision of the law of the State of New York applicable to either such agreement violates an important public policy of the State of New Mexico. (c) None of the terms of the Amendment, the Reimbursement Agreement as amended by the Amendment or the Pledge Agreement violates an important public policy of the State of New Mexico. (d) Assuming that the Amendment, the Reimbursement Agreement as amended by the Amendment and the Pledge Agreement are legal, valid and binding under the law of the State of New York, each of them constitutes the legal, valid and binding obligation of the Company, and is enforceable against the Company in accordance with its respective terms, the civil procedure of the State of New Mexico, and, subject to the opinions set forth in clauses (a), (b) and (c) of this paragraph (3), the applicable provisions of the chosen law of the State of New York. (4) After giving effect to the execution and delivery of the Amendment, the Bank continues to have a first priority perfected security interest in any Pledged Bond delivered to the Collateral Agent pursuant to and in accordance with the Pledge Agreement, and, so long as such Pledged Bond is in the possession of the Collateral Agent, no further action will be necessary to preserve, perfect or protect such security interest or the priority thereof. (For purposes of this paragraph (4), "Pledged Bond" shall have the meaning specified in the Pledge Agreement.) No opinion is expressed herein regarding the registration requirements under the Securities Act of 1933, as amended, with respect to the letter of credit issued by the Bank pursuant to the Reimbursement Agreement, as to which Mayer, Brown & Platt, counsel for the Bank, has previously delivered an opinion. We are members of the bar of the State of New Mexico and do not purport to be an expert on, or to render any opinion covering, the law of any jurisdiction other than the law of the State of New Mexico and the federal law of the United States. The opinion in paragraph (3) above is qualified to the extent that the binding effect and enforceability of the agreements and instruments referred to above are subject to applicable bankruptcy, insolvency, reorganization, moratorium, or other laws in effect from time to time affecting the rights of creditors generally and to the extent that the enforceability thereof may be limited by the application of general principles of equity. Respectfully submitted,
