(vii)Rule 433; Certain Events and Amendments or Supplements to Issuer Free Writing Prospectus: To comply with all applicable requirements of Rule 433 with respect to any Issuer Free Writing Prospectus; and if at any time after the date hereof any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the Pricing Disclosure Package and the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, to notify the Representatives and, upon their request, to file such document and to prepare and furnish without charge to each Underwriter as many copies as the Representatives may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus that will correct such conflict, statement or omission or effect such compliance;

(ii)No stop order suspending the effectiveness of the Registration Statement has been issued; no proceedings or examination for that purpose have been instituted or, to the knowledge of such officers, threatened; and the Commission has not notified the Company of any objection to the use of the form of the Registration Statement or any post-effective amendment thereto; and

(iii)They have carefully examined the Registration Statement, the Prospectus and the Pricing Disclosure Package, and, in their opinion, (A) (1) the Registration Statement, as of the Effective Date, (2) the Prospectus, as of its date and on the Delivery Date, or (3) the Pricing Disclosure Package, as of the Applicable Time, did not and do not contain any untrue statement of a material fact and did not and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in the light of the circumstances under which they were made) not misleading and (B) since the Effective Date, no event has occurred that should have been set forth in a supplement or amendment to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus that has not been so set forth.

(i)No Material Changes: Except as described in the Pricing Disclosure Package and the Prospectus, (i) neither the Company nor any of its subsidiaries shall have sustained, since the date of the latest audited financial statements included or incorporated by reference in the Pricing Disclosure Package and the Prospectus, any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree or (ii) since the date of the Pricing Disclosure Package, there shall not have been any change in the capital stock, long-term debt, consolidated net current assets or stockholders' equity of the Company and/or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), results of operations, stockholders' equity, properties, management or business of the Company and its subsidiaries taken as a whole, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Notes being delivered on the Delivery Date on the terms and in the manner contemplated in the Prospectus.

(j)No Downgrading: Subsequent to the execution and delivery of this Agreement (i) no downgrading shall have occurred in the rating accorded the Company's debt securities or preferred stock by any “nationally recognized statistical rating organization” (as that term is defined by the Commission for purposes of Rule 436(g)(2) of the Rules and Regulations), and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company's debt securities or preferred stock.

All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance as provided in exhibits to this Agreement, and if not so provided, then in form and substance reasonably satisfactory to counsel for the Underwriters.

8.Indemnification and Contribution.

(a)The Company shall indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Notes), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405) used or referred to by any Underwriter or (D) any “road show” (as defined in Rule 433) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”), (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show, any material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Notes or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Company shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or

action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct), and shall reimburse each Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e) or in a separate letter addressing such information. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter or to any director, officer, employee or controlling person of that Underwriter.

(b)Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, its directors, officers and employees, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e) or in a separate letter addressing such information. The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Company or any such director, officer, employee or controlling person.

(c)Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it

from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its respective directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and represen-tation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d)If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as

a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other, from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Company, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Notes purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Notes underwritten by it exceeds the amount of any damages that such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e)The Underwriters severally confirm and the Company acknowledges and agrees that the statements regarding delivery of the Notes by the Underwriters set forth on the cover page of, and the concession and reallowance figures and the paragraph relating to stabilization by the Underwriters appearing under the caption “Underwriting” in, the Pricing Disclosure Package and the Prospectus are correct and constitute information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the

Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show.

9.Defaulting Underwriters. If, on the Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Notes that the defaulting Underwriter agreed but failed to purchase on the Delivery Date in the respective proportions which the principal amount of the Notes set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the aggregate principal amount set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Notes on the Delivery Date if the principal amount of the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the aggregate principal amount of the Notes to be purchased on the Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of principal amount of the Notes that it agreed to purchase on the Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Notes to be purchased on the Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on the Delivery Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other Underwriters are obligated or agree to purchase the Notes of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

10.Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 7(i), 7(j) and 7(k) shall have occurred or if the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement.

11.Reimbursement of Underwriters' Expenses. If (a) the Company shall fail to tender the Notes for delivery to the Underwriters for any reason or (b) the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement, the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and

the proposed purchase of the Notes, and upon demand the Company shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

12.Research Analyst Independence. The Company acknowledges that the Underwriters' research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters' research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters' investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

13.No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering, sale of the Notes or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Notes, and such relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

14.Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

I have acted as counsel for Public Service Company of New Mexico, a New Mexico corporation (the “Company”), in connection with the issuance and sale by the Company of $160.0 million aggregate principal amount of 5.35% Senior Unsecured Notes due 2021 (the “Notes”) pursuant to the Indenture dated as of August 1, 1998, between the Company and Union Bank, N.A. (ultimate successor to The Chase Manhattan Bank), as Trustee (the “Trustee”) (the “Indenture”), as supplemented and amended by the fourth supplemental indenture to be dated as of October 12, 2011 between the Company and the Trustee (the “Supplemental Indenture”) and in accordance with that certain Underwriting Agreement dated as of October 6, 2011 between the Company and the Underwriters named therein (the “Agreement”). Capitalized terms used herein which are defined in the Agreement have the meanings set forth in the Agreement, unless otherwise defined herein.

This opinion letter is delivered to you at the request of the Company pursuant to Section 7(d) of the Agreement.

In the capacity described above, I have examined originals or copies of the following documents, which are referred to herein collectively as the “Transaction Documents”:


(a)	the Registration Statement, the Pricing Disclosure Package, the Prospectus and each Issuer Free Writing Prospectus;


(b)	the Agreement, the Indenture, the Supplemental Indenture and the global Note; and


(c)	the Agreement of Resignation, Appointment and Acceptance, effective as of June 1, 2011, by and among Texas-New Mexico Power Company, The Bank of New York Mellon Trust Company, N.A. and the Trustee.

In connection with the opinions rendered below, I have also examined copies of the following documents:

B-1-1

(a)

a certificate of the Assistant Secretary of the Company, dated ______, 2011, to which is attached: (i) the Restated Articles of Incorporation of the Company, as certified on ______, 2011, by the New Mexico Public Regulation Commission (the “NMPRC”); (ii) the Bylaws of the Company; (iii) a unanimous written consent of the Board of Directors of the Company, dated as of ____, 2011; (iv) resolutions of the Board of Directors of PNM Resources, Inc., the parent company of the Company (“PNM Resources Board”); and (v) resolutions adopted by the Pricing Committee of the PNM Resources Board at a meeting held on ______, 2011 (the “Private Certificate”);


(b)	a certificate of good standing with respect to the Company, issued by the NMPRC and a bring-down letter with respect thereto (the “Public Certificates”); and


(c)	the Final Order issued October 21, 2010 by the NMPRC in Case No. 10-00269-UT regarding the issuance of the Notes.

In addition, I have examined such other records, agreements, documents and other instruments, and such certificates or comparable documents of public officials and of officers and representatives of the Company, and have made such inquiries of such officers and representatives, as I have deemed relevant and necessary as a basis for the opinions hereinafter set forth.

As to questions of fact material to such opinions, I have, when relevant facts were not independently established, relied upon and assumed the accuracy of, with your permission, certificates of the Company and of its officers, upon certificates and comparable documents of public officials, and upon statements in the Transaction Documents.

In making the examinations of the Agreement and the other documents described above, I have assumed (i) the genuineness of all signatures (other than the signatures of the Company), (ii) the legal capacity of all natural persons, (iii) the authenticity of all documents submitted to me as originals, (iv) the conformity to original documents of all documents submitted to me as certified or photostatic copies (including telecopies) and the authenticity of the originals of such documents, (v) the correctness of all statements of fact contained in all such original documents, (vi) the due authorization, execution and delivery of all documents by all parties and the validity and binding effect thereof (other than the authorization, execution and delivery of documents by the Company, and the validity and binding effect thereof upon the Company), (vii) that all parties (other than the Company) to the Transaction Documents (x) are duly organized, validly existing and in good standing under the laws of their respective jurisdictions of organization; and (y) have the requisite power and authority to execute and deliver the documents and agreements discussed herein and to perform their respective obligations under the documents and agreements discussed herein to which they are a party; and (viii) no party nor any other person has acted in a manner, and no other event has occurred, since the date of the execution, adoption, effectiveness or delivery of the Transaction Documents, the Private Certificate or the Public Certificate or any other document reviewed by me having a date prior to the date hereof, as the case may be, that would effect an amendment, modify the interpretation thereof or cause any statement made therein not to be true and complete.

No opinion is expressed regarding compliance with covenants in any agreement to which the Company or any of its subsidiaries is a party incorporating calculations of a financial or

B-1-2

accounting nature. I have also assumed the validity and constitutionality of each relevant statute, rule, regulation and agency covered by this opinion letter.

In rendering my opinions set forth below, I have, with your approval, assumed without independent verification that the Underwriters and the Company have complied and will comply with their respective representations, warranties and agreements in the Agreement and that the offer, issuance, sale and delivery of the Notes will be carried out in the manner described in the Registration Statement.

On the basis of the foregoing, and in reliance thereon, and subject to the limitations, qualifications, assumptions, exceptions and other matters set forth herein, I am of the opinion that, as of the date hereof:

(i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of New Mexico, with full corporate power and authority to own its properties and conduct its business as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus and to enter into and to perform its obligations under, or as contemplated by, the Agreement. The Company is duly qualified to do business as a foreign corporation in good standing under the laws of each jurisdiction which requires such qualification where the failure to be so qualified would, individually, or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(ii) The Company has an authorized capitalization as set forth in each of the Registration Statement, the Pricing Disclosure Package and the Prospectus.

(iii) None of the execution, delivery and performance of the Agreement by the Company, the execution and delivery of the Supplemental Indenture and the Notes, the issue and sale of the Notes, the compliance by the Company with the Agreement, the Indenture, the Supplemental Indenture and the Notes, or the consummation of the transactions therein contemplated and the application of the proceeds from the sale of Notes as described under “Use of Proceeds” in each of the Registration Statement, the Pricing Disclosure Package and Prospectus, will (i) conflict with the charter, bylaws, or other organizational documents of the Company or any of its subsidiaries, (ii) conflict with, result in a breach or violation of, or imposition of any lien, charge or encumbrance upon any property or assets of the Company or its subsidiaries pursuant to, any statute, law, rule, regulation or, to my knowledge after reasonable inquiry, judgment, order or decree applicable to the Company of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or any of its properties or (iii) conflict with, result in a breach or violation of, or imposition of any lien, charge or encumbrance upon any property or assets of the Company or its subsidiaries, or constitute a default under any indenture, mortgage, deed of trust, loan agreement, license or other agreement or instrument known to me after reasonable inquiry to which the Company is a party or by which the Company is subject.

(iv) Other than the approval of the NMPRC, which was obtained on October 21, 2010, no consent, approval, authorization, filing with or order of any court or governmental agency or body of the State of New Mexico is required to be obtained by the Company for the execution and delivery by the Company of the Supplemental Indenture or the Agreement or for the performance by the Company of its obligations thereunder, or the issuance by the Company

B-1-3

of the Notes as described in the Supplemental Indenture, except as may be required under New Mexico securities or blue sky laws, as to which I express no opinion.

(v) To my knowledge after reasonable inquiry, and except as described in each of the Registration Statement, the Pricing Disclosure Package and the Prospectus, (A) no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or its property is pending or threatened that (1) could reasonably be expected to have a material adverse effect on the performance of the Agreement or the consummation of any of the transactions contemplated thereby or (2) could reasonably be expected to have a Material Adverse Effect; and (B) no labor disturbance by or dispute with the employees of the Company exists or is threatened or is imminent that could reasonably be expected to have a Material Adverse Effect.

(vi) Each of the Indenture and the Supplemental Indenture has been duly authorized, executed and delivered by the Company.

(vii) The Notes have been duly authorized and executed by the Company.

(viii) The Agreement has been duly and validly authorized, executed and delivered by the Company.

I am a member of the Bar of the State of New Mexico, and, for purposes of this opinion, do not hold myself out as an expert on the laws of any jurisdiction other than the State of New Mexico and express no opinion as to any choice of law matters nor as to, or the effect or applicability of, any laws other than the laws of the State of New Mexico, except that I express no opinion as to the applicability of, or compliance with, New Mexico “blue sky” or state securities laws. The opinions herein are expressed as of the date hereof, and I assume no obligation to revise, update or supplement such opinions to reflect any change in any fact or circumstance that hereafter comes to my attention, or any change in law that may hereafter occur, whether by legislative action, judicial decision, or in any other manner. This opinion letter is furnished only to you in connection with the contemplated transactions and is solely for your benefit. This opinion letter may not be used, relied upon, circulated, quoted or otherwise referred to for any purpose without my prior written consent (including by any person who acquires Notes from the Underwriters), except as may be required by applicable law or regulation.

▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

We have acted as counsel for Public Service Company of New Mexico, a New Mexico corporation (the “Company”), in connection with the issuance and sale by the Company of $160.0 million aggregate principal amount of its 5.35% Senior Unsecured Notes due 2021 (the “Notes”) pursuant to the Indenture, dated as of August 1, 1998, between the Company and Union Bank, N.A. (ultimate successor to The Chase Manhattan Bank), as Trustee (the “Trustee”) (the “Indenture”), as supplemented and amended by the fourth supplemental indenture to be dated as of October 12, 2011 between the Company and the Trustee (the “Supplemental Indenture”) and in accordance with that certain Underwriting Agreement dated as of October 6, 2011 between the Company and the Underwriters named therein (the “Agreement”). Capitalized terms used herein which are defined in the Agreement have the meanings set forth in the Agreement, unless otherwise defined herein.

This opinion letter is delivered to you at the request of the Company pursuant to Section 7(d) of the Agreement.

In the capacity described above, we have examined originals or copies of the following documents, which are referred to herein collectively as the “Transaction Documents”:


(a)	the Registration Statement, the Pricing Disclosure Package, the Prospectus and each Issuer Free Writing Prospectus;


(b)	the Agreement, the Indenture, the Supplemental Indenture, and the global Note; and

In connection with the opinions rendered below, we have also examined copies of the following documents:


(a)	a certificate of the Secretary of the Company, dated ______, 2011, to which is attached: (i) the Restated Articles of Incorporation of the Company, as certified

B-2-1

(b)	a certificate of good standing with respect to the Company, issued by the NMPRC and a bring-down letter with respect thereto (the “Public Certificates”).

In addition, we have examined such other records, agreements, documents and other instruments, and such certificates or comparable documents of public officials and of officers and representatives of the Company, and have made such inquiries of such officers and representatives, as we have deemed relevant and necessary as a basis for the opinions hereinafter set forth.

As to questions of fact material to such opinions, we have, when relevant facts were not independently established, relied upon and assumed the accuracy of, with your permission, certificates of the Company and of its officers, upon certificates and comparable documents of public officials, and upon statements in the Transaction Documents. As to all matters of New Mexico law, including the opinion set out in paragraphs 1 and 2 below, to the extent that it relates to New Mexico law, we are relying exclusively on the opinion letter of ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇, Associate General Counsel, SEC Reporting and Corporate Transactions, of the Company, dated _________, 2011.

As used herein, the phrase “to the best of our knowledge” refers to the actual conscious awareness of attorneys of this firm who have devoted substantive attention to matters on behalf of the Company. Without limiting the generality of the foregoing, we have not performed any mathematic calculations or made any financial or accounting determinations and express no opinion with respect to the ability of any party to perform under any documents (other than, with respect to the Company under the Transaction Documents). All assumptions made by us herein have been made, with your approval.

In making the examinations of the Agreement and the other documents described above, we have assumed (i) the genuineness of all signatures (other than the signatures of the Company), (ii) the legal capacity of all natural persons, (iii) the authenticity of all documents submitted to us as originals, (iv) the conformity to original documents of all documents submitted to us as certified or photostatic copies (including telecopies) and the authenticity of the originals of such documents, (v) the correctness of all statements of fact contained in all such original documents, (vi) the due authorization, execution and delivery of all documents by all parties and the validity and binding effect thereof (other than the authorization, execution and delivery of documents by the Company, and the validity and binding effect thereof upon the Company), (vii) that all parties (other than the Company) to the Transaction Documents (x) are duly organized, validly existing and in good standing under the laws of their respective jurisdictions of organization; and (y) have the requisite power and authority to execute and deliver the documents and agreements discussed herein and to perform their respective obligations under the documents and agreements discussed herein to which they are a party; and (viii) no party nor any other person has acted in a manner, and no other event has occurred, since

B-2-2

the date of the execution, adoption, effectiveness or delivery of the Transaction Documents, the Private Certificate or the Public Certificate or any other document reviewed by us having a date prior to the date hereof, as the case may be, that would effect an amendment, modify the interpretation thereof or cause any statement made therein not to be true and complete.

No opinion is expressed regarding compliance with covenants in any agreement to which the Company or any of its subsidiaries is a party incorporating calculations of a financial or accounting nature. We have also assumed the validity and constitutionality of each relevant statute, rule, regulation and agency covered by this opinion letter.

We have not conducted a docket search or otherwise conducted an independent review or investigation of any official records of any court or governmental agency. In rendering our opinions set forth below, we have, with your approval, assumed without independent verification that the Underwriters and the Company have complied and will comply with their respective representations, warranties and agreements in the Agreement and that the offer, issuance, sale and delivery of the Notes will be carried out in the manner described in the Registration Statement.

On the basis of the foregoing, and in reliance thereon, and subject to the limitations, qualifications, assumptions, exceptions and other matters set forth herein, we are of the opinion that, as of the date hereof:

(1) Each of the Indenture and the Supplemental Indenture constitutes a valid and binding agreement of the Company enforceable against the Company in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, reorganization or similar laws relating to or affecting creditors' rights generally and by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law); and the Indenture has been duly qualified under the Trust Indenture Act.

(2) When authenticated by the Trustee in accordance with the Indenture and delivered to the Underwriters against payment therefor in accordance with the terms of the Agreement, the Notes will have been validly issued and delivered and will constitute valid and binding obligations of the Company entitled to the benefits of the Indenture and the Supplemental Indenture and enforceable against the Company in accordance with their terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization or other similar laws relating to or affecting the enforcement of creditors' rights generally and by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(3) The statements set forth in the Registration Statement, the Pricing Disclosure Package and the Prospectus under the caption “Description of Notes” and “Description of Senior Unsecured Notes” insofar as they purport to constitute a summary of the terms of the securities, are accurate summaries in all material respects.

Prospectus will conflict with, result in a breach or violation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, (A) the statutes, laws, rules, regulations or, to our knowledge, any judgment, order or decree applicable to the Company or any of its subsidiaries of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or any of its subsidiaries or any of its or their properties, or (B) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which the Company is a party or bound or to which its property is subject and which is filed as an exhibit to the Company's most recent Annual Report on Form 10-K filed with the Commission.

B-2-4

We have participated in conferences with officers and other representatives of the Company at which the contents of the Registration Statement, the Prospectus, the Preliminary Prospectus and related matters were discussed and we have consulted with officers and other employees of the Company to inform them of the disclosure requirements under the Securities Act. We have examined various reports, records, contracts and other documents of the Company and orders and instruments of public officials, which our investigation led us to deem pertinent. In addition, we participated in one or more due diligence conferences with representatives of the Company and attended the closing at which the Company satisfied the conditions contained in Section 7 of the Agreement. We have not, however, undertaken to make any independent review of other records of the Company which our investigation did not lead us to deem pertinent. As to the statistical statements in the Pricing Disclosure Package, Prospectus and Registration Statement (which includes the documents incorporated by reference therein), we have relied solely on the officers of the Company. We accordingly assume no responsibility for the accuracy, completeness or fairness of the statements contained in the Pricing Disclosure Package, the Prospectus or the Registration Statement, except as specifically stated in numbered opinion (8) above, and we have not made any independent check or verification thereof. But such conferences, consultation, examination and attendance disclosed to us no information with respect to such other matters that gives us reason to believe that and, on the basis of the foregoing, no facts have come to our attention which have led us to believe that (i) the Registration Statement, as of the Effective Date and as of October 6, 2011, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Prospectus, as of its date and as of the date hereof, contained or contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or (iii) the most recent Preliminary Prospectus, together with the Issuer Free Writing Prospectuses in the Pricing Disclosure Package, as of the Applicable Time, contained or contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; in each case, except with respect to the financial statements and other financial or statistical data included in or incorporated by reference in the Registration Statement, the Prospectus, the most recent Preliminary Prospectus and the Issuer Free Writing Prospectus in the Disclosure Package, as to which we express no opinion.

The Agreement is governed by the laws of the State of New York. We express no opinion as to, or the effect or applicability of, any laws other than the laws of the State of New York and the federal laws of the United States of America. We express no opinion as to the applicability of, or compliance with, any state securities or blue sky laws, municipal law or the laws of any local agencies within any state (including, without limitation, within the state of New York). This opinion letter is limited to the matters stated herein, and no opinion is implied or may be inferred beyond the matters expressly stated herein.

Our opinions are as of the date hereof and we have no responsibility to update these opinions for events and circumstances occurring after the date hereof or as to facts relating to prior events that are subsequently brought to our attention. We disavow any undertaking to advise you of any changes in law.

No opinion is given as to the enforceability of any provision of any document that waives any obligation of good faith, fair dealing, diligence, materiality or reasonableness, that insulates any person from the consequences of its own misconduct, that makes a person's determinations conclusive, that requires waivers and modifications to be in writing in all circumstances, that states that all provisions are severable, that waives trial by jury or that makes a choice of forum. No opinion is given as to any provision in any document purporting to waive rights to objections, legal defenses, statutes of limitations or other benefits that cannot be waived in advance under applicable law.

Our opinions expressed herein represent the judgment of this law firm as to certain legal matters, but they are not guarantees or warranties and should not be construed as such.

The opinions herein are expressed as of the date hereof, and we assume no obligation to revise, update or supplement such opinions to reflect any change in any fact or circumstance that hereafter comes to our attention, or any change in law that may hereafter occur, whether by legislative action, judicial decision, or in any other manner.

Ladies and Gentlemen:

Our firm has been retained as special Arizona counsel for Public Service Company of New Mexico (the “Company”) in connection with (i) the issuance by the Company of $160.0 million aggregate principal amount of its 5.35% Senior Unsecured Notes due 2021 (the “Notes”) pursuant to the Indenture dated as of August 1, 1998 between the Company and Union Bank, N.A.

Capitalized terms used herein which are defined in the Agreement have the meanings set forth in the Agreement, unless otherwise defined herein.

This opinion letter is being delivered to you at the request of the Company pursuant to Section 7(d) of the Agreement.

In connection with the opinions herein contained, we have examined, among other things, the following:

B-3-1

(4) such other documents, certificates, and records as we have deemed relevant and necessary as a basis for the opinions hereinafter set forth.

As to matters of fact material to the opinions hereinafter expressed, we have relied, without independent investigation, on certificates or statements of the Company or of public officials and on relevant public records. As to matters of fact material to the opinions hereinafter expressed and dealt with in such certificate, we have relied solely on the certificate of the Company attached hereto as Exhibit A (the “Company Certificate”), and no other investigation or inquiry with respect thereto has been made.

We have assumed, and have not verified (i) that each of the Notes, the Agreement, and the Supplemental Indenture (the “Documents”) provided to us in unsigned form will be duly executed and delivered in substantially the form provided to us; (ii) the actual execution of the conformed copies of the Documents provided to us, the genuineness of the signatures not witnessed, the authenticity of such Documents submitted as originals and the conformity to originals of such Documents submitted as copies; (iii) the legal competency and capacity and due authority of each individual signing the Documents; and (iv) that the Documents accurately and completely describe and contain the mutual intent, understanding and business purpose of the parties, and that there are no oral or written statements or agreements, understandings or negotiations, nor any usage of trade or course of prior dealing among the parties that directly or indirectly modify, define, amend, supplement, or vary, or purport to modify, define, amend, supplement, or vary, any of the terms of such documents or any of the parties' rights or obligations thereunder, by waiver or otherwise.

Based on the foregoing, it is our opinion that, insofar only as the laws of the State of Arizona are concerned:

1. The Company is duly qualified as a foreign corporation and is in good standing under the laws of the State of Arizona. The opinions expressed in the immediately preceding sentence are based solely on the Good Standing Certificate, a copy of which has been made available to you and your counsel, and our opinions with respect to such matters are rendered as of the date of such certificate and are limited accordingly.

2. No consent, approval, authorization, filing with or order of any court or governmental agency or body of the State of Arizona is legally required for the execution and delivery by the Company of the Supplemental Indenture or the Agreement or for the performance by the Company of its obligations thereunder, or the issuance by the Company of the Notes as described in the Supplemental Indenture, except as may be required under Arizona securities or blue sky laws, as to which we express no opinion.

The opinions herein are limited solely to the laws of the State of Arizona and we express no opinion on the laws of any other jurisdiction. Other than pursuant to paragraph 1 above, we express no opinion on any tax laws or related matters in the State of Arizona.

The opinions expressed herein are based upon the law and facts in effect on the date hereof, and we assume no obligation to revise or supplement this opinion should such law be changed by legislative action, judicial decision, or in any other manner, or otherwise to notify

B-3-2

you of any changes in law or fact relevant to the opinions expressed herein. Except as described in the next paragraph below, this opinion letter is rendered solely for your benefit in connection with the transactions described above, and this opinion letter is not to be used, circulated, quoted, or otherwise referred to for any other purpose.

A copy of this opinion is being delivered to the Trustee, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ LLP and ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇, Esq., Associate General Counsel, SEC Reporting and Corporate Transactions, of PNM Resources, Inc. and may be considered by such persons, for all intents and purposes, to have the same force and effect as if it were directed to them.
