You should read this summary together with the Indenture, and the officer's certificatesany supplemental indentures or other documents establishing the SUNs for a complete understanding of the provisions that may be important to you. You should also read this prospectus and any applicable prospectus supplement before you make any investment decision. The following descriptions of the SUNs and the Indenture are qualified by reference to the Indenture, which is filed as an exhibit to the registration statement of which this prospectus is a part. References to certain sections of the Indenture are included in parentheses.

The Indenture provides that the applicable SUNs will be issued in one or more series, may be issued at various times, may have differing maturity dates and may bear interest at differing rates.  We need not issue all SUNs of one series at the same time and, unless otherwise provided, we may reopen a series, without the consent of the holders of the SUNs of that series for issuances of additional SUNs of that series.
The prospectus supplement relating to any series of SUNs being offered will include specific terms relating to that offering. These terms will include any of the following terms that apply to that series: - - the title of the SUNs; - - the total principal amount of the SUNs; - - the date or dates on which the principal of the SUNs will be payable and how it will be paid; 3 - - the rate or rates at which the SUNs will bear interest, if any, and how the rate or rates will be determined; - - the date or dates from which interest on the SUNs will accrue, the interest payment dates on which interest will be paid, and the record dates for the interest payments; - - the right, if any, to extend the interest payment periods for the SUNs and the duration of the extension; - - the place or places where payments will be made; - - whether we have the option to redeem the SUNs and, if so, the terms of our redemption option; - - any sinking fund or other provisions or options held by holders of the SUNs that would obligate us to repurchase or otherwise redeem the SUNs; - - if the SUNs will be issued in denominations other than $1,000; - - any index or formula used for determining principal, premium or interest; - - the currency in which payments will be made if other than United States dollars, and the manner of determining the equivalent of those amounts in United States dollars; - - if payments may be made on any of the SUNs, at our election or at the holder's election, in a currency other than that in which the SUNs are stated to be payable, then the currency in which those payments may be made, the terms and conditions of the election and the manner of determining those amounts; - - the portion of the principal payable upon acceleration of maturity, if other than the entire principal; - - if the principal payable on the maturity date will not be determinable on one or more dates prior to the maturity date, the amount which will be deemed to be such principal amount or the manner of determining it; - - whether the provisions described under "Discharge, Defeasance and Covenant Defeasance" will apply to the SUNs; - - whether the SUNs will be issuable as global securities and, if so, the securities depositary; - - any changes or additions to the events of default under the Indenture or changes or additions to our covenants under the Indenture; and - - any other terms of the SUNs not inconsistent with the terms of the Indenture.

(See Section 3.01)
All SUNs of any one series will be substantially identical except as to denomination and except as may otherwise be determined in the manner provided for in the Indenture. (See Section 3.01)
The SUNs are not secured by any property or assets and represent our unsecured debt obligations. As discussed below under " - Restrictions on Liens and - Restrictions on Sale and Lease-Back Transactions," the Indenture contains certain limitations on our ability to create liens and enter into sale and leaseback transactions. Such limitations do not afford holders of the SUNs protection in the event of a highly 4 leveraged or other transaction involving us that may adversely affect the holders of the SUNs. The Indenture does not limit our ability to pay dividends or limit our ability to incur other unsecured and unsubordinated debt ranking equally with all of our existing and future unsecured and unsubordinated obligations. However, debt to capital requirements in certain of our financial instruments and regulatory agreements would limit the amount of additional debt we could issue.
SUNs may be sold at a substantial discount below their principal amount. You should consult the applicable prospectus supplement for a description of certain special United States federal income tax considerations which may apply to SUNs sold at an original issue discount or denominated in a currency other than United States dollars. GLOBAL SUNS
Global SUNs
We may issue some or all of the SUNs as book-entry securities. Any such book-entry securities will be represented by one or more fully registered global securities. We will register each global security with or on behalf of a securities depositary identified in the applicable prospectus supplement. Each global security will be deposited with the securities depositary or its nominee or a custodian for the securities depositary.
7

As long as the securities depositary or its nominee is the registered holder of a global security representing SUNs, that person will be considered the sole owner and holder of the global security and the SUNs it represents for all purposes. Except in limited circumstances, owners of beneficial interests in a global security: - - may not have the global security or any of the SUNs it represents registered in their names; - - may not receive or be entitled to receive physical delivery of certificated SUNs in exchange for the global security; and - - will not be considered the owners or holders of the global security or any of the SUNs it represents for any purposes under the SUNs or the Indenture.
●  may not have the global security or any of the SUNs it represents registered in their names;
●  may not receive or be entitled to receive physical delivery of certificated SUNs in exchange for the global security; and
●  will not be considered the owners or holders of the global security or any of the SUNs it represents for any purposes under the SUNs or the Indenture.

We will make all payments of principal and any premium and interest on a global security to the securities depositary or its nominee as the holder of the global security. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security.

Ownership of beneficial interests in a global security will be limited to institutions having accounts with the securities depositary or its nominee, which are called "participants"“participants” in this discussion, and to persons that hold beneficial interests through participants. When a global security representing SUNs is issued, the securities depositary will credit on its book entry, registration and transfer system the principal amounts of SUNs the global security represents to the accounts of its participants. Ownership of beneficial interests in a global security will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by: - - the securities depositary, with respect to participants' interests; and - - any participant, with respect to interests the participant holds on behalf of other persons.
●  the securities depositary, with respect to participants’ interests; and
●  any participant, with respect to interests the participant holds on behalf of other persons.

Payments to owners of beneficial interests held through participants will be the responsibility of those participants. The securities depositary may from time to time adopt various policies and procedures 5 governing payments, transfers, exchanges and other matters relating to beneficial interests in a global security. None of the following will have any responsibility or liability for any aspect of the securities depositary'sdepositary’s or any participant'sparticipant’s records relating to beneficial interests in a global security representing SUNs, for payments made on account of those beneficial interests or for maintaining, supervising or reviewing any records relating to those beneficial interests: - - PNM; - - the Trustee; or - - an agent of either of them. REDEMPTION

●  PNM;
●  the Trustee; or
an agent of either of them.
Redemption
We will set forth any terms for the redemption of the SUNs in a prospectus supplement. Unless we indicate differently in a prospectus supplement, the SUNs will be redeemable upon notice by mail to the holders between 30 and 60 days prior to the redemption date. If less than all of the SUNs of any series are to be redeemed, the Trustee will select the SUNs to be redeemed. In the absence of any provision for selection, the Trustee will choose a method of random selection that it deems fair and appropriate. (See Sections 11.03 and 11.04)
The SUNs will cease to bear interest on the redemption date. We will pay the redemption price and any accrued interest once the SUNs are surrendered for redemption. (See Section 11.06) If only part of a SUN is redeemed, the Trustee will deliver to you a new SUN of the same series for the remaining portion without charge. (See Section 11.07)
8

We may make any redemption, at our option, conditional upon the receipt by the paying agent or agents, on or prior to the date fixed for redemption, of money sufficient to pay the redemption price. If the paying agent or agents have not received the money by the date fixed for redemption, we will not be required to redeem the SUNs. (See Section 11.04) PAYMENT
Payment
Except as may be provided in the prospectus supplement, interest, if any, on each SUN payable on each interest payment date will be paid to the person in whose name the SUN is registered as of the close of business on the regular record date for the interest payment date. Interest payable at maturity, however, will be paid to the person to whom the principal is paid. If there has been a default in the payment of interest on any SUN, the defaulted interest may be paid to the holder of that SUN as of the close of business on a date to be fixed by the Trustee, which will be between 10 and 15 days prior to the date we proposed for payment of the defaulted interest, orand not less than 10 days after receipt by the Trustee of the notice of the proposed payment.  The defaulted interest may also be paid in any other manner permitted by any securities exchange on which that SUN may be listed, if the Trustee finds it practicable. (See Section 3.07) REGISTRATION OF TRANSFER AND EXCHANGE
Registration of Transfer and Exchange
Unless otherwise specified in a prospectus supplement, the transfer of the SUNs may be registered, and the SUNs may be exchanged for other SUNs of the same series, of authorized denominations and with the same terms and principal amount, at the corporate trust office of the Trustee. We may change the place for registration of transfer and exchange of the SUNs and may designate additional places for registration and exchange. Unless otherwise provided in the prospectus supplement, no service charge will be made for any transfer or exchange of the SUNs. However, we may require payment to cover any 6 tax or other governmental charge that may be imposed. We will not be required to execute or to provide for the registration of transfer of, or the exchange of: - - any SUN during a period of 15 days prior to giving any notice of redemption; or - - any SUN selected for redemption except the unredeemed portion of any SUN being redeemed in part. (See
●  any SUN during a period of 15 days prior to giving any notice of redemption; or
●  any SUN selected for redemption except the unredeemed portion of any SUN being redeemed in part.
(See Section 3.05) RESTRICTIONS ON LIENS

●  Mortgages on any property (x) which, at any time subsequent to January 1, 1985 through the date of the Indenture, was leased to us, or (y) pursuant to the terms of any lease to us in effect at any time subsequent to January 1, 1985 through the date of the Indenture, title to which would not have been vested in us (assuming that the lease remained in effect on the date of determination as the lease was in effect immediately prior to the date of the Indenture);
●  the extension, renewal or replacement of any Mortgage referred to above; provided, however, that the principal amount of Debt so secured and not otherwise authorized by the previous clauses, shall not exceed the principal amount of Debt, plus any premium or fee payable in connection with any such extension, renewal, or replacement, so secured at the time of such extension, renewal, or replacement.
Notwithstanding the foregoing, so long as any SUNs are outstanding, we may issue, assume, or guarantee Debt, or permit to exist Debt, secured by mortgages which would otherwise be subject to the foregoing restrictions up to an aggregate principal amount that, together with the principal amount of all of our other Debt, secured by mortgages (other than mortgages permitted by the Indenture that would otherwise be subject to the foregoing restrictions) and the Value (as defined below) of all Sale and Lease- 7 BackLease-Back Transactions (as defined below) in existence at such time (other than certain Sale and Lease-Back Transactions specified in the Indenture), does not exceed at the time the greater of ten percent (10%) of Net Tangible Assets (as defined below) or ten percent (10%) of Capitalization (as defined below).

(See Section 9.01)
If the Trust Indenture Act of 1939 is amended after the date of the Indenture to require changes to the Indenture, the Indenture will be deemed to be amended so as to conform to that amendment of the Trust Indenture Act of 1939. We and the Trustee may, without the consent of any of the holders, enter into one or more supplemental indentures to evidence that amendment. (See Section 9.01)
The consent of the holders of a majority in aggregate principal amount of the SUNs of all series then outstanding, considered as one class, is required for all other modifications to the Indenture. However, if less than all of the series of SUNs outstanding are directly affected by a proposed supplemental indenture, then only the consent of the holders of a majority in aggregate principal amount of the outstanding SUNs of all series that are directly affected will be required. No amendment or modification may: - - change the stated maturity of the principal of, or any installment of principal of or interest on, any SUN, or reduce the principal amount of any SUN or its rate of interest or change the method of calculating the interest rate or reduce any premium payable upon redemption, or change the currency in which payments are made, or impair the right to institute suit for the enforcement of any payment on or after the stated maturity of any SUN, without the consent of the holder; - - reduce the percentage in principal amount of the outstanding SUNs of any series which consent is required for any supplemental indenture or any waiver of compliance with a provision of the Indenture or any default thereunder and its consequences, or reduce the requirements for quorum or voting, without the consent of all the holders of the series; or - - modify certain provisions of the Indenture relating to supplemental indentures, waivers of certain covenants and waivers of past defaults with respect to the SUNs of any series, without the consent of the holder of each outstanding SUN affected thereby.

●  reduce the percentage in principal amount of the outstanding SUNs of any series the consent of which is required for any supplemental indenture or any waiver of compliance with a provision of the Indenture or any default thereunder and its consequences, or reduce the requirements for quorum or voting, without the consent of all the holders of the series; or
●  modify certain provisions of the Indenture relating to supplemental indentures, waivers of certain covenants and waivers of past defaults with respect to the SUNs of any series, without the consent of the holder of each outstanding SUN affected thereby.
(See Section 9.02)
A supplemental indenture which changes the Indenture solely for the benefit of one or more particular series of SUNs, or modifies the rights of the holders of the SUNs of one or more series, will not affect the rights under the Indenture of the holders of the SUNs of any other series. (See Section 9.02)
The Indenture provides that the SUNs owned by us or anyone else required to make payment on the SUNs will be disregarded and considered not to be outstanding in determining whether the required holders have given a request or consent. (See Section 1.01)
We may fix in advance a record date to determine the required number of holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or other such act of the holders, in certain situations. If the record date is fixed, the holders of the outstanding SUNs of the relevant series on that record date, and no other holders, will be entitled to take or revoke the relevant action, whether or not those holders remain holders after that record date. No action, however, will be effective unless taken on or prior to the applicable expiration date by holders of the requisite principal amount of the outstanding SUNs of that series on that record date. Any request, demand, authorization, direction, notice, consent, election, waiver or other act of a holder will bind every future holder of the same SUNs and the holder of every SUN issued upon the registration of transfer of or in exchange of those SUNs. A transferee will be bound by our acts or those of the Trustee taken in reliance thereon, whether or not notation of that action is made upon that SUN. (See Section 1.04) 11 EVENTS OF DEFAULT "Event

(See Section 5.01). REMEDIES
Remedies
Acceleration of Maturity
If an event of default with respect to any one series of SUNs occurs and continues, either the Trustee or the holders of a majority in principal amount of the outstanding SUNs of that series may declare the principal amount of all the SUNs of that series to be due and payable immediately. However, if the event of default is applicable to more than one series of SUNs, the Trustee or the holders of a majority in principal amount of all the outstanding SUNs of all series, considered as one class, and not the holders of any one series, may make a declaration of acceleration. (See Section 5.02)
At any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee, the event of default giving rise to the declaration of acceleration will be considered waived, and the declaration and its consequences will be consideredautomatically rescinded and annulled, if: - - we have paid or deposited with the Trustee a sum sufficient to pay: - all overdue interest on all the SUNs of the series; - the principal of and premium, if any, on any SUNs of the series which have otherwise become due and interest, if any, that is currently due; - interest, if any, on overdue interest (to the extent lawful); and - all amounts due to the Trustee under the Indenture; and 12 - - any other event of default with respect to the SUNs of that series has been cured or waived as provided in the Indenture. (See
●  we have paid or deposited with the Trustee a sum sufficient to pay:
                     ●  all overdue interest on all the SUNs of the series;
                     ●  the principal of and premium, if any, on any SUNs of the series which have otherwise become due and interest, if any, that is currently due;
                     ●  interest, if any, on overdue interest (to the extent lawful);
                     ●  all amounts due to the Trustee under the Indenture; and
●  any other event of default with respect to the SUNs of that series has been cured or waived as provided in the Indenture.
(See Section 5.02)
14

The holders of a majority in principal amount of the outstanding SUNs of any series may on behalf of the holders of all the SUNs of that series waive any past default under the Indenture with respect to that series and its consequences, except a default (i) in the payment of the principal of or any premium or interest on any SUN of that series, or (ii) in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of the holder of each outstanding SUN of the series affected. However, if a default occurs and continues with respect to more than one series of SUNs, the holders of a majority in aggregate principal amount of the outstanding SUNs of all such series, considered as one class, hashave the right to waive the default, and not the holders of the SUNs of any one such series. Upon any waiver, the default ceases to exist, and any and all events of default arising therefrom is deemed to have been cured, for every purpose of the Indenture; but no waiver will extend to any subsequent or other default or impair any right consequent thereon. (See Section 5.13)
Right to Direct Proceedings
If an event of default with respect to any series of SUNs occurs and continues, the holders of a majority in principal amount of the outstanding SUNs of that series have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the SUNs of that series.  However, if an event of default occurs and continues with respect to more than one series of SUNs, the holders of a majority in aggregate principal amount of the outstanding SUNs of all such series, considered as one class, have the right to make the direction, and not the holders of the SUNs of any one of such series and that (i) such direction will not be in conflict with any rule of law or with the Indenture; (ii) the Trustee may take any other action deemed proper by the Trustee and not inconsistent with direction, and (iii) subject to the provisions ofseries.  In either case, the Indenture the Trustee will have the right to decline to follow any direction if the Trustee in good faith determines that the proceeding so directed would involve the Trustee in personal liability. (Seefurther provides that:
●  such direction will not be in conflict with any rule of law or with the Indenture;
●  the Trustee may take any other action deemed proper by the Trustee and not inconsistent with direction, and
●  subject to the provisions of the Indenture the Trustee will have the right to decline to follow any direction if the Trustee in good faith determines that the proceeding so directed would involve the Trustee in personal liability.
(See Section 5.12)
Limitation on Right to Institute Proceedings
No holder of SUNs of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy under the Indenture, unless: - - the holder has previously given to the Trustee written notice of a continuing event of default; - - the holders of a majority in aggregate principal amount of the outstanding SUNs of all series in respect of which an event of default has occurred and is continuing, considered as one class, have made a written request to the Trustee, and have offered reasonable indemnity to the Trustee to institute proceedings; and - - the Trustee has failed to institute any proceeding for 60 days after notice and has not received any direction inconsistent with the written request of the holders during that period. (See
●  the holder has previously given to the Trustee written notice of a continuing event of default;
●  the holders of a majority in aggregate principal amount of the outstanding SUNs of all series in respect of which an event of default has occurred and is continuing, considered as one class, have made a written request to the Trustee;
●  such holder or holders have offered reasonable indemnity to the Trustee to institute proceedings; and
●  the Trustee has failed to institute any proceeding for 60 days after notice and has not received any direction inconsistent with the written request of the holders during that period.

No Impairment of Right to Receive Payment 13
The limitations on the right to institute proceedings, however, do not apply to a suit by a holder of a SUN for payment of the principal of or premium, if any, or interest if any, on that SUN on or after the applicable due date. (See Section 5.08)
Annual Notice to Trustee
We will provide to the Trustee an annual statement by an appropriate officer as to whether we are in default in the performance and observance of any of the terms, provisions and conditions of the Indenture. (See Section 10.04) NOTICES
Notices
Notices to holders of the SUNs will be given by mail to the holders at the addresses that appear in the security register. (See Section 1.06) TITLE

Item 15.     INDEMNIFICATION OF DIRECTORS AND OFFICERS. Indemnification of Directors and Officers.
Section 7 of Article II of Public Service Company of New Mexico'sMexico’s Bylaws contains the following provisions with respect to indemnification of directors and officers:
Each person serving as a director or an officer of the Corporation, or, at the request of the Corporation, as a director or an officer of any other company in which the Corporation has a financial interest and regardless of whether or not the person is then in office, and the heirs, executors, administrators and personal representatives of the person, shall be indemnified by the Corporation to the full extent of the authority of the Corporation to so indemnify as authorized by New Mexico law.
Section 53-11-4.1 of the Business Corporation Act of the State of New Mexico provides that a corporation shall have power to indemnify any person made (or threatened to be made) a party to any proceeding (whether threatened, pending or completed) by reason of the fact that the person is or was a director (or, while a director, is or was serving in any of certain other capacities) if: (1) the person acted in good faith; (2) the person reasonably believed: (a) in the case of conduct in the person'sperson’s official capacity with the corporation, that the person'sperson’s conduct was in its best interests; and (b) in all other cases, that the person'sperson’s conduct was at least not opposed to its best interests; and (3) in the case of any criminal proceeding, the person had no reasonable cause to believe the person'sperson’s conduct was unlawful. Indemnification may be made against judgments, penalties, fines, settlements and reasonable expenses actually incurred by the person in connection with the proceeding, but may be limited or unavailable with respect to certain proceedings. In some instances, indemnification of a director may be mandatory or, upon the application of a director, may be ordered by a court. Reasonable expenses incurred by a director may, under certain circumstances, be paid or reimbursed in advance of a final disposition of a proceeding. Unless limited by its articles of incorporation, a corporation may (or, as the case may be, shall) indemnify and advance expenses to an officer of the corporation to the same extent as to a director under Section 53-11-4.1. Also, unless limited by its articles of incorporation, a corporation has (1) the power to indemnify and to advance expenses to an employee or agent of the corporation to the same extent that it may indemnify and advance expenses to directors under the statute and (2)
II-1

additional power to indemnify and II-1 to advance reasonable expenses to an officer, employee or agent who is not a director to such further extent, consistent with law, as may be provided by its articles of incorporation, bylaws, general or specific action of its Board of Directors, or contract.
Section 53-11-4.1 was amended in 1987 to provide that the indemnification authorized thereunder shall not be deemed exclusive of any rights to which those seeking indemnification may be entitled under the articles of incorporation, the by-laws, an agreement, a resolution of shareholders or directors or otherwise. PNM has entered into agreements with each director and officer which provide for indemnification of directors and officers to the fullest extent permitted by law including advancement of litigation expenses where appropriate. The agreements provide for the appointment of a reviewing party by the Board of Directors to make a determination whether claimed indemnification is permitted under applicable law.
Insurance is maintained on a regular basis (and not specifically in connection with this offering) against liabilities arising on the part of directors and officers out of their performance in such capacities or arising on the part of PNM out of its foregoing indemnification provisions, subject to certain exclusions and to the policy limits.
