For purposes of the foregoing proviso, "Excess Funds" shall mean, for any day, amounts actually paid to the Trustee under the Pledged Lessor Notes in excess of amounts then due and payable in respect of Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee shall thereupon authenticate and deliver such Securities in accordance with such Company Order, without any further action by the Company.

Receipt by the Trustee of the Officer's Certificate referred to in clause (2) above shall be conclusively presumed for all purposes of this Indenture to establish that the Lease Indentures, the Leases and the Pledged Lessor Notes referred to in such certification comply with the requirements of Exhibit A hereto. The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised by counsel, determines that such action may not lawfully be taken by the Company or if the Trustee in good faith by its board of directors or board of trustees, executive committee, or a trust committee of directors or trustees and/or responsible officers shall determine that such action would expose the Trustee to personal liability. SECTION 1.005. Form and Denominations. The Securities of each series shall be in registered form and may have such letters, numbers or other marks of identification and such legends or endorsements printed, lithographed or engraved thereon, as may be required to comply with the rules of any securities exchange or to conform to any usage in respect thereof, or as may, consistently herewith, be prescribed by the Board of Directors of the Company or by the officers executing such Securities, such determination by said officers to be evidenced by their signing the Securities. The definitive Securities shall be printed, lithographed or engraved or produced by any combination of these methods on steel engraved borders or may be produced in any other manner permitted by the rules of any securities exchange, all as determined by the officers executing such Securities, as evidenced by their execution of such Securities. All Securities of any one series shall be substantially identical except as to denomination and Stated Maturity and except as may otherwise be provided herein or in the Series Supplemental Indenture setting forth the terms of the Securities of such series. SECTION 1.006. Execution of Securities. The Securities shall be executed on behalf of the Company by its President or one of its Vice Presidents under its corporate seal reproduced thereon and attested by its Secretary or one of its Assistant Secretaries. The signature of any such officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at the time such signatures were affixed the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. SECTION 1.007. Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities of such series which are printed, lithographed, typewritten, photocopied or otherwise produced, in any denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. If temporary Securities of any series are issued, the Company will cause definitive Securities of such series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such #30122041.1 13 series at the office or agency of the Company, for such purpose, in the Place of Payment, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like aggregate principal amount of definitive Securities of such series of authorized denominations. Until so exchanged such temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. SECTION 1.008. Registration, Transfer and Exchange. The Trustee shall cause to be kept at the Corporate Trust Office a register in which, subject to such reasonable regulations as the Company may prescribe, the Company shall provide for the registration of Securities and of registration of transfers and exchanges of Securities. This register and, if there shall be more than one Security Registrar, the combined registers maintained by all such Security Registrars, are herein sometimes referred to as the "Security Register". Upon surrender for registration of transfer of any Security of any series at the Corporate Trust Office, or at any office or agency maintained for such purpose pursuant to Section 9.14(a), the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series and of the same Stated Maturity for principal and interest and of a like aggregate principal amount. At the option of the Holders, Securities of any series may be exchanged for an equal aggregate principal amount of Securities of the same series and of the same Stated Maturity for principal and interest and of any authorized denominations, upon surrender of the Securities to be exchanged at the Corporate Trust Office, or at any office or agency maintained for such purpose pursuant to Section 9.14(a). Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee or any other Authenticating Agent shall authenticate and deliver, the Securities which the Securityholder making the exchange is entitled to receive. All Securities issued upon any transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same security and benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. Every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. No service charge shall be required of any Securityholders participating in any transfer or exchange of Securities in respect of such transfer or exchange, but the Security Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Securities, other than exchanges pursuant to Sections 2.07, 6.06 or 11.07 not involving any transfer. The Security Registrar shall not be required (i) to issue, transfer or exchange any Security of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of such series selected for redemption under Section 6.02 or 7.02 and ending at the close of business on the day of such mailing, or (ii) to transfer or exchange any Security so selected for redemption in whole or in part except the unredeemed portion of any Security selected for redemption in part. SECTION 1.009. Mutilated, Destroyed, Lost and Stolen Securities. If (i) any mutilated Security is surrendered to the Trustee, or the Company, the Security Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and (ii) there is delivered to the Company, to the Security Registrar and to the Trustee evidence to their satisfaction of the ownership and authenticity thereof, and such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company, to the Security Registrar or to the Trustee that such Security has been acquired by a bona fide #30122041.1 14 purchaser, the Company shall execute and upon its request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company may, upon satisfaction of the conditions set forth in clauses (i) and (ii) of the preceding paragraph, instead of issuing a new Security, pay such Security. Upon the issuance of any new Security under this Section, the Security Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the security and benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. SECTION 1.10. Payment of Interest; Interest Rights Preserved. Interest on any Security which is payable, and is punctually paid or duly provided for, at any Stated Maturity of an installment of interest shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. At the option of the Company, payment of interest on any Security may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, at any Stated Maturity of an installment of interest shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder; and such defaulted interest may be paid by the Company, at its election in each case, as provided in paragraph (1) or paragraph (2) below: (1) The Company may elect, which election shall be at the direction of any Lessor whose Pledged Lessor Note is in default in respect of the payment of interest and who is proposing to make payment of all or part of such defaulted interest, to make payment of any defaulted interest to the Persons in whose names the Securities of such series in respect of which interest is in default (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such defaulted interest, which shall be fixed in the following manner. Such Lessor shall notify the Trustee and the Paying Agent in writing of the amount of defaulted interest proposed to be paid on each such Security and the date of the proposed payment, and at the same time there shall be deposited with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or there shall be made arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as in this paragraph provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such defaulted interest which shall be not more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company and the Security Registrar of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such defaulted interest and the Special Record Date therefor to be mailed, first class postage prepaid, to each holder of a Security of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such defaulted interest and the #30122041.1 15 Special Record Date therefor having been mailed as aforesaid, such defaulted interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered on such Special Record Date and shall no longer be payable pursuant to the following paragraph (2). (2) The Company may make, or cause to be made, payment of any defaulted interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities in respect of which interest is in default may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this paragraph, such payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security, and each such Security shall bear interest from whatever date shall be necessary so that neither gain nor loss in interest shall result from such transfer, exchange or replacement. SECTION 1.11. Persons Deemed Owners. Prior to due presentment for registration of transfer, the Person in whose name any Security is registered shall be deemed to be the owner of such Security for the purpose of receiving payment of principal of (and premium, if any), and (subject to Section 2.10) interest on, such Security and for all other purposes whatsoever, whether or not such Security be overdue, regardless of any notice to anyone to the contrary. SECTION 1.12. Cancellation. All Securities surrendered for payment, redemption, credit against any Sinking Fund payment or redemption payment, transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee for cancellation. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be destroyed and certification of their destruction delivered to the Company unless, by Company Request, the Company otherwise directs. SECTION 1.13. Dating of Securities; Authentication. Each Security of any series shall be dated the date of the original issuance of the Securities of such series by the Company, which date shall be specified by the Company in the Company Order delivered to the Trustee pursuant to Section 2.04 in connection with the original authentication and delivery of the Securities of such series. No Security shall be secured by or entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication, in the form provided for herein, executed by the Trustee by the manual signature of one of its Responsible Officers, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. SECTION 1.14. Source of Payments; Rights and Liabilities of Lessors and Equity Investors. All payments of principal and premium (if any) and interest to be made under the Securities and this Indenture (other than payments made in connection with an optional redemption by a Lessor) shall be made only from assets subject to the lien of this Indenture or the income and proceeds received by the Trustee therefrom. Each Holder, by its acceptance of a Security, agrees that (x) it will look solely to the assets subject to the lien of this Indenture or the income and proceeds received by the Trustee therefrom to the extent available for distribution to such Holder as herein provided and (y) none of any Equity Investor, any Lessor, any Lease Indenture Trustee or the Trustee is liable to any Holder or, in the case of any Equity Investor, Lessor and Lease Indenture Trustee, to the Trustee for any amounts payable under any Security or, #30122041.1 16 except as provided herein with respect to the Trustee, for any liability under this Indenture. An Equity Investor, Lessor or Lease Indenture Trustee shall not have any duty or responsibility under this Indenture or the Securities to any Holder or to the Trustee. SECTION 1.15. Sale of Securities; and Application of Proceeds from the Sale of Securities. (a) Promptly upon receipt by the Company of the proceeds from any sale of a series of the Securities, the Company shall deposit such proceeds with the Trustee. The funds so deposited shall be held by the Trustee in a separate account as part of the Pledged Property and shall be invested, applied and distributed by the Trustee as provided herein. (b) Subject to the provisions of Section 13.01, upon the issuance of the Pledged Lessor Notes related to any series of Securities and the delivery thereof to the Trustee to be subjected to the Lien of this Indenture pursuant to a Series Supplemental Indenture, the Trustee shall pay to the Lessor obligated in respect of any such Pledged Lessor Note, out of funds held by the Trustee in such separate account as Pledged Property, an amount equal to the principal amount of such Pledged Lessor Note in respect of which such Lessor is obligated. All payments to be made by the Trustee to any Lessor shall be made in immediately available funds at the respective offices designated by such Lessor. ARTICLE II. PROVISIONS AS TO PLEDGED PROPERTY SECTION 1.001. Holding of Pledged Securities. The Trustee is authorized in its discretion to cause to be registered in its name, as Trustee, or in the name of its nominee, any and all coupon bonds which it may receive as part of the Pledged Property, or it may cause the same to be exchanged for registered bonds without coupons of any denomination. The Trustee may cause to be transferred into its name, as Trustee, or into the name of its nominee, any and all registered bonds which it may receive as part of the Pledged Property, or may cause such registered bonds to be exchanged for coupon bonds.

In addition, any Securityholder may at any time request the Trustee to direct, or to participate in the direction of, any action under any Lease Indenture to the extent that the Trustee may do so under such Lease Indenture. In directing any action or casting any vote as the holder of a Pledged Lessor Note, the Trustee shall specify to the Lease Indenture Trustee the principal amount of the Pledged Lessor Note which is in favor of the action or vote, the principal amount of the Pledged Lessor Note which is opposed to the action or vote, and the principal amount of the Pledged Lessor Note which is not taking any position for the action or vote. Such principal amounts shall be determined by allocating the total principal amount of the Pledged Lessor Note with respect to which direction was requested in accordance with the principal amount of Securities taking corresponding positions or not taking any position.

COVENANTS SECTION 1.021. Payment of Principal, Premium (if any) and Interest.

(b) Subject to the provisions of subsection (c) of this Section 5.09, the Trustee may consent to any Change in any Principal Instrument if such Change is: (1) to cure any ambiguity, to correct or supplement any provision in such Principal Instrument which may be defective or inconsistent with any other provision in such Principal Instrument or any related Principal Instrument, or to make any other provisions with respect to matters arising under any such Principal Instrument, provided, in each instance, that such action shall not materially adversely affect the interests of Holders of Securities; or (2) to add to the covenants and agreements of the parties to such Principal Instrument other covenants and agreements hereafter to be observed by any such party, or to surrender any right or power therein reserved to or conferred upon the Company; or (3) to amend or supplement such Principal Instrument, or to give any consent or grant any waiver thereunder, so long as thereafter such Principal Instrument will comply with the requirements (if any) of Exhibit A hereto; provided that such action does not materially adversely affect the interests of Holders of Securities; or (4) in any other manner not inconsistent with Exhibit A hereto; provided that such action does not materially adversely affect the interests of Holders of Securities; or (5) Change in the Lease permitted by applicable provisions of the related Lease Indenture; or (6) to describe more fully and to amplify or correct the description of any property or rights assigned or pledged by such Principal Instrument or intended so to be, or to assign, pledge, mortgage or grant a security interest in any additional property, rights and interests, subject to such liens, restrictions or other encumbrances, if any, as shall be therein specifically described; or (7) in the case of a Lease Indenture, to enable the Lease Indenture Trustee thereunder to confer upon holders of Pledged Lessor Notes any additional rights, remedies, powers or authorities that may lawfully be granted or conferred upon such holders; or (8) to evidence the appointment of a separate or co-Lease Indenture Trustee or the succession of a new Lease Indenture Trustee; or (9) to evidence the succession of or assumption by a successor or assignee Lessee under the Leases and the Participation Agreements or to evidence the succession of a new Lessor or Owner Trustee under any Principal Document to which it is a party; or #30122041.1 22 (10) permitted by the terms of such Principal Instrument to be made without the consent of or notice to the holders of the related Pledged Lessor Notes; or (11) to provide for the issuance of Lessor Notes in addition to the Pledged Lessor Notes relating to such Principal Instruments in accordance with the applicable provisions of the related Principal Instruments.

SECTION 1.10. Annual Statement as to Compliance. (a) PNM and the Company each will deliver to the Trustee, on or before 120 days after the end of each of its fiscal years, a written statement (which need not comply with Section 1.02) signed by its President or one of its Vice Presidents and by its Treasurer or one of its Assistance Treasurers or its Comptroller or one of its Assistant Comptrollers, stating, as to each signer thereof, that (1) a review of the activities of PNM or the Company, as the case may be, required during such year of PNM or the Company, as the case may be, under this Indenture has been made under his supervision; and (2) to the best of his knowledge, based on such review, PNM or the Company, as the case may be, has fulfilled all its obligations under this Indenture throughout such year, or, if there has been a default in the fulfillment of any such obligation, specifying each such default known to such officer and the nature and status thereof. (b) PNM and the Company each will deliver to the Trustee, promptly after having obtained knowledge thereof, but in no event later than five days thereafter, written notice of any event which with the giving of notice or lapse of time, or both, would become an Event of Default under Section 8.01. #30122041.1 23 ARTICLE II. REDEMPTION OF SECURITIES The provisions of this Article Six shall be applicable to the Securities of any series which are redeemable before their Stated Maturity of principal except as otherwise provided in such Securities or the Series Supplemental Indenture with respect thereto as contemplated by Section 2.03. SECTION 1.001. Notice to Trustee of Redemption. In case of any redemption of any Securities of any series otherwise than through the operation of an applicable Sinking Fund, the Company shall, at least 45 days prior to the scheduled Redemption Date (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of Securities of such series to be redeemed. SECTION 1.002. Selection by Trustee of Securities to be Redeemed. If fewer than all the Securities of any series are to be redeemed, other than through the operation of an applicable Sinking Fund, the particular Securities of such series to be redeemed shall be selected following receipt by the Trustee of the notice required by Section 6.01, but not more than 60 days prior to the Redemption Date, by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions of the principal of Securities of any denomination larger than $1,000; provided, however, that for purposes of selecting Securities of any series for redemption pursuant to this Section, Securities of such series shall be redeemed from each Stated Maturity of principal of Securities of such series as nearly as practicable in the proportion that the aggregate principal amount of Securities of such series of such Stated Maturity of principal Outstanding immediately prior to the Redemption Date shall bear to the aggregate principal amount of Securities of such series of all Stated Maturities of principal then Outstanding, in each case taking into account in the determination of Securities Outstanding the Securities of such series subject to such redemption; provided further, however, that when Securities are being redeemed pursuant to any applicable optional (rather than mandatory) redemption provisions, the Securities to be redeemed shall be selected solely from the Securities of the series and of the Stated Maturity of principal in respect of which a Company Order has been received. If Securities are to be selected for any redemption pursuant to this Section, the Trustee may make such adjustments as it shall deem necessary so that the principal amount of Securities redeemed shall be $1,000 or an integral multiple thereof, such adjustments to be made by the Trustee in such manner as the Trustee in its sole discretion deems appropriate. The Trustee shall promptly notify the Company, PNM, the Security Registrar and the Paying Agent in writing of the Securities selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal of such Security which has been or is to be redeemed. SECTION 1.003. Notice of Redemption. Notice of redemption (including redemption through the operation of any applicable Sinking Fund) shall be given by first-class mail, postage prepaid, mailed not less than 20 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. All notices of redemption shall state: #30122041.1 24 (1) the Redemption Date, (2) the Redemption Price, (3) if fewer than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the respective principal amounts) of the particular Securities, including the series and the Stated Maturity of principal of such Securities, to be redeemed, (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security, and that interest thereon shall cease to accrue from and after said date, (5) the place where such Securities are to be surrendered for payment of the Redemption Price, and (6) that the redemption is through the operation of a Sinking Fund, if such is the case. Notice of redemption of Securities to be redeemed shall be given by the Trustee in the name of the Company. SECTION 1.004. Deposit of Redemption Price. Prior to any Redemption Date, the Company shall deposit, or cause to be deposited, with the Paying Agent an amount of money sufficient to pay the Redemption Price of all the Securities which are to be redeemed on that date. SECTION 1.005. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the corporate trust office of the Paying Agent (or, if such office is not in the Borough of Manhattan, the City of New York, at either such office or an office to be maintained in such Borough) at the Redemption Price therein specified and from and after such date (unless there shall be a default in the payment of the Redemption Price) such Securities shall cease to bear interest. Upon surrender of such Securities for redemption in accordance with said notice, such Securities shall be paid at the Redemption Price, exclusive, however, of installments of interest maturing on or prior to the Redemption Date, payment of which shall have been made or duly provided for to the Holders of such Securities registered as such on the relevant Record Dates, or otherwise, according to their terms and the provisions of Section 2.10. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, continue to bear interest from the Redemption Date at the rate borne by the Security in respect of overdue payments. SECTION 1.006. Securities Redeemed in Part. Any Security which is to be redeemed only in part shall be surrendered at the corporate trust office of the Paying Agent (or, if such office is not in the Borough of Manhattan, the City of New York, at either such office or an office to be maintained in such Borough) (with due endorsement by, or a written instrument of transfer in form satisfactory to the Security Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Paying Agent for delivery to the Holder of such Security a new Security or Securities of the same series and the same Stated Maturity of principal, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. #30122041.1 25 ARTICLE I. SINKING FUNDS SECTION 1.011. Sinking Funds for Securities. [(a)] The amount of any sinking fund payment provided for by the terms of Securities of any series (and any Stated Maturity of principal within a series) is herein referred to as a "Sinking Fund", and the date on which a Sinking Fund payment is to be made is herein referred to as a "Sinking Fund Date." Each such Sinking Fund payment shall be applied to the redemption of Securities of the appropriate series and the appropriate Stated Maturity of principal on the appropriate Sinking Fund Date. [(b)] In the event that there shall have been any partial redemption of a series of Securities (other than pursuant to an applicable Sinking Fund), the amount of each applicable Sinking Fund payment of a particular Stated Maturity of principal within such series subsequent to such redemption shall be reduced by an amount equal to the amount obtained by (i) multiplying the amount of such Sinking Fund payment with respect to such Stated Maturity of principal as in effect prior to such redemption by a fraction of which the numerator shall be the aggregate principal amount of Securities of such Stated Maturity of such series redeemed pursuant to such partial redemption, and the denominator shall be the aggregate principal amount of Securities of such Stated Maturity of such series Outstanding immediately prior to such redemption, and (ii) rounding the amount indicated in (i) to the nearest $1,000, subject to necessary adjustment so that the total amount of such reduction is equal to the total principal amount of Securities redeemed pursuant to such partial redemption, such adjustment to be made by the Trustee in such manner as the Trustee in its sole discretion deems appropriate. [(c)] Pursuant to the Series 1986A Series Supplemental Indenture dated as of July 15, 1986 (the Series 1986A Supplement), the Company issued a series of Securities designated "Lease Obligation Bonds Series 1986A" (the Series A Bonds), of which, on June 1, 1994 two Stated Maturities of principal remain outstanding: July 15, 1996 and January 15, 2014. Paragraph (b) of Section 7.01 of the Original Indenture to the contrary notwithstanding, in the event that there shall have been any partial redemption of Series A Bonds of a particular Stated Maturity of principal (other than pursuant to the Sinking Fund), the Sinking Fund payments thereafter to be made with respect to such Series A Bonds shall be adjusted as follows. The Company shall first identify all related Pledged Lessor Notes (as defined in Article II of Series 1986A Supplement and identified in Schedule 2 thereto) having the same maturity as the Series A Bonds of such particular Stated Maturity of principal redeemed, if any, which are outstanding following such redemption; provided, however, that for purposes of this Section 7.01(c), any such Pledged Lessor Notes with a maturity subsequent to January 15, 2010 shall be deemed to have a maturity of January 15, 2014. Having identified all such outstanding Pledged Lessor Notes (the Outstanding Notes), the Company shall determine the dates on which the principal of such Outstanding Notes is to be amortized (the Scheduled Amortization Dates). The amount of the Sinking Fund payment scheduled to be made on each Sinking Fund Date subsequent to the date of such partial redemption shall then be adjusted to equal the aggregate principal amount of all Outstanding Notes scheduled to be amortized on the Scheduled Amortization Date corresponding to such Sinking Fund Date. All such adjustments in respect of Sinking Fund payments on a Sinking Fund Date shall be rounded to the nearest $1,000, and shall be subject to necessary further adjustment so that the total amount of such reduction is at least equal to the total principal amount of Series A Bonds redeemed pursuant to such partial redemption. Having made the calculations required by the preceding two sentences, the Company shall deliver to the Trustee a Company Request not later than 30 days following any partial redemption of Series A Bonds (other than pursuant to the Sinking Fund), setting forth (x) the schedules of principal amortization of all related Outstanding Notes having the same maturity as the Stated Maturity of principal of the Series A Bonds redeemed and (y) a revised schedule of Sinking Fund payments applicable to Series A Bonds having the same Stated Maturity of principal as the Series A Bonds redeemed. The Trustee may rely on such Company Request and shall have no duty with respect to the adjustments set forth therein other than to make them available for inspection by a Holder of Series A Bonds at the Corporate Trust Office uponreasonable notice.]2 #30122041.1 26 SECTION 1.012. Selection by Trustee of Securities to be Redeemed Through Operation of Sinking Fund. In the case of Securities to be redeemed through operation of the Sinking Fund, the particular Securities to be redeemed shall be selected no more than 60 days nor less than 30 days prior to the Redemption Date by the Trustee from the outstanding Securities of the same series and of the same Stated Maturity of principal not previously called for redemption by prorating, as nearly as may be, the principal amount of Securities to be redeemed among the Holders of Securities of the same series and of the same Stated Maturity of principal registered in their respective names. In any proration pursuant to this Section, the Trustee shall make such adjustments, reallocations and eliminations as it shall deem proper so that the principal amount of Securities so prorated shall be $1,000 or an integral multiple thereof, by increasing or decreasing or eliminating the amount which would be allocable to any Holder on the basis of exact proportion by an amount not exceeding $1,000. The Trustee in its discretion may determine the particular Securities of a Stated Maturity of principal registered in the name of any Holder which are to be redeemed, in whole or in part. Notwithstanding the provisions of the preceding paragraph, if, at the time of any such selection, there shall be any Holders of less than $1,000,000 aggregate principal amount of Outstanding Securities of the series and of the Stated Maturity of principal to be so redeemed, the selection of the particular Securities to be so redeemed shall be made in the following manner: (a) the Trustee shall first prorate the principal amount of Securities of such series and of such Stated Maturity to be so redeemed between (i) Holders of Securities in aggregate principal amounts of $1,000,000 or more and (ii) Holders of Securities in aggregate principal amounts of less than $1,000,000; such proration to be effected in accordance with the respective aggregate principal amounts of such Securities held by the Holders referred to in the foregoing items (i) and (ii), respectively; (b) the Trustee shall then select for redemption in the manner hereinabove in the first paragraph of this Section 7.02 provided, from the Securities of such series and Stated Maturity held by the Holders referred to in item (i) of clause (a) above, particular Securities (or portions thereof) in the principal amount prorated to such Holders pursuant to said clause (a); and (c) the Trustee shall then select for redemption in the manner provided in Section 6.02 hereof, from the Securities of such series and Stated Maturity held by the Holders referred to in item (ii) of said clause (a), particular Securities (or portions thereof) in the principal amount prorated to such Holders pursuant to said clause (a); provided, however, in any such prorating pursuant to this paragraph the Trustee may, according to such method as it shall deem proper in its discretion, make such adjustments by increasing or decreasing by not more than $1,000 the amount which would be allocable on the basis of an exact proportion, as may be necessary to the end that the principal amount so prorated shall be in each instance an integral multiple of $1,000. - -------- 2 Bracketed language added by 1994 Supplemental Indenture. See Exhibit F. #30122041.1 27 ARTICLE II. EVENTS OF DEFAULT; REMEDIES SECTION 1.021. Events of Default.

Acceleration of Maturity; Rescission and Annulment. Upon the occurrence of an Event of Default, (i) if such Event of Default is one referred to in clause (1), (2), (3), (4), (6) or (7) of Section 8.01, the Trustee may, and upon the direction of the Holders of not less than 25% in principal amount of the Securities Outstanding shall, and (ii) if such Event of Default is the one referred to in clause (5) of Section 8.01 (including without limitation an event of default under any Lease which has resulted in an Event of Default referred to in clause (1), (2), or (3) of Section 8.01), the Trustee shall, declare the principal of all the Securities to be due and payable immediately, by a notice in writing to PNM and the Company, and upon any such declaration such principal shall become immediately due and payable; provided that no such declaration shall be made (and no action under Section 8.03 or 8.05 shall be taken) in cases in which the Event of Default is one referred to in clause (1), (2), or (3) of Section 8.01 which resulted directly from a failure of PNM to make any payment of rent under any Lease until such time as the Lessor under such Lease has been given the opportunity to exercise its rights, if any, under provisions of the related Lease Indenture analogous to Section 6.8 of the Lease Indentures dated as of December 16, 1985. At any time after such a declaration of acceleration has been made and before any sale of the Pledged Property, or any part thereof, shall have been made pursuant to any power of sale as hereinafter in this Article; provided, the Holders of a majority in principal amount of the Securities Outstanding, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if (1) there shall have been paid to or deposited with the Trustee a sum sufficient to pay (A) all overdue installments of interest on all Securities, (B) the principal of (and premium, if any, on) any Securities which have become due otherwise than by such declaration of acceleration and interest thereon at the respective rates provided in the Securities for late payments of principal or premium, (C) to the extent that payment of such interest is lawful, interest upon overdue installments of interest at the respective rates provided in the Securities for late payments of interest, and (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (2) all Events of Default, other than the non-payment of the principal of Securities which have become due solely by such acceleration, have been cured or waived as provided in Section 8.08. No such rescission shall affect any subsequent default or impair any right consequent thereon. [and no such annulment shall take place unless all declarations of acceleration of all Pledged Lessor Notes theretofore given have also been annulled in accordance with the terms of the applicable Lease Indentures.]3 [Notwithstanding anything in this Section to the contrary, the Trustee shall rescind any acceleration of maturity of the principal of and interest on the Securities as a consequence of an Event of Default which resulted from an event of default under any Lease and which resulted in a declaration of acceleration of the Pledged Lessor Notes issued under the related Lease Indenture, if the declaration of acceleration of such Pledged Lessor Notes has been rescinded in accordance with the terms of such Lease Indenture and the conditions set forth in paragraphs (1) and (2) of this Section have been met.]4 - -------- 3 This language was deleted by paragraph (b)(ii) of Article III of the 1986A Bond Supplemental Indenture.

In the event that the Trustee shall deem it advisable to sell any of or all the Pledged Property in accordance with the provisions of this Section, PNM and the Company agree that if registration of any such Pledged Property shall be required, in the opinion of counsel for the Trustee, under the Securities Act of 1933 or other applicable law, and regulations promulgated thereunder, and if PNM shall not effect, or cause to be effected, such registration promptly, the Trustee may sell any such Pledged Property at a private sale, and no Person shall attempt to maintain that the prices at which such Pledged Property is sold are inadequate by reason of the failure to sell at public sale, or hold the Trustee liable therefor.

(ii) if and so long as the number of directors of the Trustee in office is more than nine, one additional individual may be director or an executive officer, or both, of the Trustee and a director of an obligor on the Securities; and (iii) the Trustee may be designated by an obligor on the Securities or by any underwriter for such obligor to act in the capacity of transfer agent, registrar, custodian, paying agent, fiscal agent, escrow agent, or depositary, or in any other similar capacity, or, subject to the provisions of paragraph (1) of this Subsection, to act as trustee, whether under an indenture or otherwise;

As to any such securities of which the Trustee acquired ownership through becoming executor, administrator, or testamentary trustee of an estate which included them, the provisions of the preceding sentence shall not apply, for a period of two years from the date of such acquisition to the extent that such securities included in such estate do not exceed 25% of such voting securities or 25% of any such class of security.

The specification of percentages in paragraphs (5) to (9) inclusive, of this Subsection, shall not be construed as indicating that the ownership of such percentages of the securities of a person is or is not necessary or sufficient to constitute direct or indirect control for the purposes of paragraph (3) or (7) of this Subsection. For the purposes of paragraphs (6), (7), (8) and (9) of this Subsection only, (i) the terms "security" and "securities" shall include only such securities as are generally known as corporate securities, but shall not include any note or other evidence of indebtedness issued to evidence an obligation to repay moneys loaned to a person by one or more banks, trust companies or banking firms, or any certificate of interest or participation in any such note or evidence or indebtedness; (ii) an obligation shall be deemed to be "in default" when a default in payment of principal shall have continued for 30 days or more and shall not have been cured; and (iii) the Trustee shall not be deemed to be the owner or holder of (A) any security which it holds as collateral security, as trustee or otherwise, for an obligation which is not in default as defined in clause (ii) above, or (B) any security which it holds as collateral security under this Indenture, irrespective of any default hereunder, or (C) any security which it holds as agent for collection, or as custodian, escrow agent, or depositary, or in any similar representative capacity.

(4) The term "voting security" means any security presently entitling the owner or holder thereof to vote in the direction or management of the affairs of a person, or any security issued under or pursuant to any trust, agreement or arrangement whereby a trustee or trustees or agent or agents for the owner or holder of such security are presently entitled to vote in the direction or management of the affairs of a person.

(5) A security shall be deemed to be of the same class as another security if both securities confer upon the holder or holders substantially the same rights and privileges; provided, however, that in the case of secured evidences of indebtedness, all of which are issued under a single indenture, differences in the interest rates or maturity dates of various series thereof shall not be deemed sufficient to constitute such series different classes; and provided, further, that, in the case of unsecured evidences of indebtedness, differences in the interest rates or maturity dates thereof shall not be deemed sufficient to constitute them securities of different classes, whether or not they are issued under a single indenture.

There shall at all times be a Trustee hereunder which shall be a corporation organized and doing business under the laws of the United States of America or of any State, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000, and subject to supervision or examination by Federal or State authority.

If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. SECTION 1.10. Resignation and Removal; Appointment of Successor. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee under Section 9.11. (b) The Trustee may resign at any time by giving written notice thereof to PNM and the Company.

(c) The Trustee may be removed at any time by Act of the Holders of a majority in principal amount of the Outstanding Securities, delivered to the Trustee, PNM and to the Company. #30122041.1 43 (d) If at any time: (i) the Trustee shall fail to comply with Section 9.08(a) after written request therefor by any Lessor or by any Securityholder who has been a bona fide Holder of a Security for at least 6 months, or (ii) the Trustee shall cease to be eligible under Section 9.09 and shall fail to resign after written request therefor by any Lessor or by any such Securityholder, or (iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) PNM, acting after consultation with the Company, may remove the Trustee by Board Resolution or (ii) subject to Section 8.10, any Securityholder who has been a bona fide Holder of a Security for at least 6 months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, PNM, acting after consultation with the Company, shall promptly appoint by Board Resolution a successor Trustee. If, within 1 year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities delivered to PNM, the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by PNM. If no successor Trustee shall have been so appointed by PNM, acting after consultation with the Company, or by the Securityholders, and accepted appointment in the manner hereinafter provided, any Securityholder who has been a bona fide Holder of a Security for at least 6 months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to PNM, the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of any Lessor, the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its lien, if any, provided for in Section 9.07. Upon request of any such successor Trustee, PNM and the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. #30122041.1 44 SECTION 1.12.

In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. SECTION 1.13. Preferential Collection of Claims against any Obligor. [(a) Subject to Subsection (b) of this Section, if the Trustee shall be or shall become a creditor, directly or indirectly, secured or unsecured, of any obligor on the Securities (as defined in Subsection (c) of this Section) within 4 months prior to a default, as defined in Subsection (c) of this Section, or subsequent to such a default, then, unless and until such default shall be cured, the Trustee shall set apart and hold in a special account for the benefit of the Trustee individually, the Holders of the Securities and the holders of other indenture securities (as defined in Subsection (c) of this Section): (i) an amount equal to any and all reductions in the amount due and owing upon any claim as such creditor in respect of principal or interest, effected after the beginning of such 4 month period and valid as against any obligor on the Securities and its other creditors, except any such reduction resulting from the receipt or disposition of any property described in paragraph (ii) of this Subsection, or from the exercise of any right of set-off which the Trustee could have exercised if a petition in bankruptcy had been filed by or against any such obligor upon the date of such default; and (ii) all property received by the Trustee in respect of any claim as such creditor, either as security therefor, or in satisfaction or composition thereof, or otherwise, after the beginning of such 4 month period, or an amount equal to the proceeds of any such property, if disposed of, subject, however, to the rights, if any, of any obligor on the Securities and its other creditors in such property or such proceeds. Nothing herein contained, however, shall affect the right of the Trustee (A) to retain for its own account (i) payments made on account of any such claim by any Person (other than an obligor on the Securities) who is liable thereon, and (ii) the proceeds of the bona fide sale of any such claim by the Trustee to a third person, and (iii) distributions made in cash, securities or other property in respect of claims filed against such obligor in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Act or applicable State law; (B) to realize, for its own account, upon any property held by it as security for any such claim, if such property was so held prior to the beginning of such 4 month period; (C) to realize, for its own account, but only to the extent of the claim hereinafter mentioned, upon any property held by it as security for any such claim, if such claim was created after the beginning of such 4 month period and such property was received as security therefor simultaneously with the creation thereof, #30122041.1 45 and if the Trustee shall sustain the burden of proving that at the time such property was so received the Trustee had no reasonable cause to believe that a default as defined in Subsection (c) of this Section would occur within 4 months; or (D) to receive payment on any claim referred to in paragraph (B) or (C), against the release of any property held as security for such claim as provided in paragraph (B) or (C), as the case may be, to the extent of the fair value of such property. For the purposes of paragraphs (B), (C) and (D), property substituted after the beginning of such 4 month period for property held as security at the time of such substitution shall, to the extent of the fair value of the property released, have the same status as the property released, and, to the extent that any claim referred to in any of such paragraphs is created in renewal of or in substitution for or for the purpose of repaying or refunding any pre-existing claim of the Trustee as such creditor, such claim shall have the same status as such pre-existing claim. If the Trustee shall be required to account, the funds and property held in such special account and the proceeds thereof shall be apportioned between the Trustee, the Securityholders and the holders of other indenture securities in such manner that the Trustee, the Securityholders and the holders of other indenture securities realize, as a result of payments from such special account and payments of dividends on claims filed against the obligor on the Securities in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Act or applicable State law, the same percentage of their respective claims, figured before crediting to the claim of the Trustee anything on account of the receipt by it from such obligor of the funds and property in such special account and before crediting to the respective claims of the Trustee and the Securityholders and the holders of other indenture securities dividends on claims filed against such obligor in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Act or applicable State law, but after crediting thereon receipts on account of the indebtedness represented by their respective claims from all sources other than from such dividends and from the funds and property so held in such special account. As used in this paragraph, with respect to any claim, the term "dividends" shall include any distribution with respect to such claim, in bankruptcy or receivership or proceedings for reorganization pursuant to the Federal Bankruptcy Act or applicable State law, whether such distribution is made in cash, securities, or other property, but shall not include any such distribution with respect to the secured portion, if any, of such claim. The court in which such bankruptcy, receivership or proceedings for reorganization is pending shall have jurisdiction (i) to apportion between the Trustee and the Securityholders and the holders of other indenture securities, in accordance with the provisions of this paragraph, the funds and property held in such special account and proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to the provisions of this paragraph due consideration in determining the fairness of the distributions to be made to the Trustee and the Securityholders and the holders of other indenture securities with respect to their respective claims, in which event it shall not be necessary to liquidate or to appraise the value of any securities or other property held in such special account or as security for any such claim, or to make a specific allocation of such distributions as between the secured and unsecured portions of such claims, or otherwise to apply the provisions of this paragraph as a mathematical formula. Any Trustee which has resigned or been removed after the beginning of such 4 month period shall be subject to the provisions of this Subsection as though such resignation or removal had not occurred. If any Trustee has resigned or been removed prior to the beginning of such 4 month period, it shall be subject to the provisions of this Subsection if and only if the following conditions exist: (i) the receipt of property or reduction of claim, which would have given rise to the obligation to account if such Trustee had continued as Trustee, occurred after the beginning of such 4 month period; and (ii) such receipt of property or reduction of claim occurred within 4 months after such resignation or removal. #30122041.1 46 (b) There shall be excluded from the operation of Subsection (a) of this Section a creditor relationship arising from (1) the ownership or acquisition of securities issued under any indenture, or any security or securities having a maturity of one year or more at the time of acquisition by the Trustee; (2) advances authorized by a receivership or bankruptcy court of competent jurisdiction, or by this Indenture, for the purpose of preserving any property which shall at any time be subject to the lien of this Indenture or of discharging tax liens or other prior liens or encumbrances thereon, if notice of such advances and of the circumstances surrounding the making thereof is given to the Securityholders at the time and in the manner provided in this Indenture; (3) disbursements made in the ordinary course of business in the capacity of trustee under an indenture, transfer agent, registrar, custodian, paying agent, fiscal agent or depositary, or other similar capacity; (4) an indebtedness created as a result of services rendered or premises rented; or an indebtedness created as a result of goods or securities sold in a cash transaction as defined in Subsection (c) of this Section; (5) the ownership of stock or of other securities of a corporation organized under the provisions of Section 25(a) of the Federal Reserve Act, as amended, which is directly or indirectly a creditor of PNM; or (6) the acquisition, ownership, acceptance or negotiation of any drafts, bills of exchange, acceptances or obligations which fall within the classification of self-liquidating paper as defined in Subsection (c) of this Section. (c) For the purposes of this Section only: (1) The term "default" means any failure to make payment in full of the principal of or interest on any of the Securities or upon the other indenture securities when and as such principal or interest becomes due and payable. (2) The term "other indenture securities" means securities upon which the Person obligated thereunder is an obligor (as defined in the Trust Indenture Act) outstanding under any other indenture (i) under which the Trustee is also trustee, (ii) which contains provisions substantially similar to the provisions of this Section, and (iii) under which a default exists at the time of the apportionment of the funds and property held in a special account as provided in Subsection (a) of this Section. (3) The term "cash transaction" means any transaction in which full payment for goods or securities sold is made within 7 days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand. (4) The term "self-liquidating paper" means any draft, bill of exchange, acceptance or obligation which is made, drawn, negotiated or incurred by any obligor on the Securities for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship with such obligor arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation. #30122041.1 47 (5) The term "obligor" means any obligor upon the Securities within the meaning of the TIA. SECTION 1.14. Maintenance of Agencies. (a) There shall at all times be maintained in the Borough of Manhattan, the City of New York, an office or agency where Securities may be presented or surrendered for transfer or exchange or for the registration thereof, and for payment of principal, premium (if any) and interest and where notices and demands to or upon the Trustee in respect of the Securities or of this Indenture may be served. Such office or agency shall be initially at the Corporate Trust Office of Chemical Bank. Written notice of the location of each such other office or agency and of any change of location thereof shall be given to the Company and to the Trustee. In the event that no such office or agency shall be maintained or no such notice of location or of change of location shall be given, presentations and demands may be made and notices may be served at the Corporate Trust Office. (b) There shall at all times be a Security Registrar and a Paying Agent hereunder. Each such Authorized Agent shall be a bank or trust company, shall be a corporation organized and doing business under the laws of the United States or any State thereof, with a combined capital and surplus of at least $50,000,000, and shall be authorized under such laws to exercise corporate trust powers, subject to supervision by Federal or State authorities. Chemical Bank is hereby appointed as Paying Agent and Security Registrar hereunder. Each Security Registrar (other than the Trustee) shall furnish to the Trustee, at stated intervals of not more than 6 months, and at such other times as the Trustee may request in writing, a copy of the Security Register. (c) Any Paying Agent (other than the Trustee) from time to time appointed hereunder shall execute and deliver to the Trustee an instrument in which said Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) hold all sums held by it for the payment of principal of, and premium (if any) and interest on Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee within five days thereafter notice of any default by any obligor upon the Securities in the making of any such payment of principal, premium (if any) or interest; and (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. Notwithstanding any other provision of this Indenture, any payment required to be made to or received or held by the Trustee may, to the extent authorized by written instructions of the Trustee, be made to or received or held by a Paying Agent in the Borough of Manhattan, the City of New York, for the account of the Trustee. (d) Any corporation into which any Authorized Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, consolidation or conversion to which any Authorized Agent shall be a party, or any corporation succeeding to the corporate trust business of any Authorized Agent, shall be the successor of such Authorized Agent hereunder, if such successor corporation is otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the parties hereto or such Authorized Agent or such successor corporation. (e) Any Authorized Agent may at any time resign by giving written notice of resignation to the Trustee, PNM and the Company. The Company may, and at the request of the Trustee or any Lessor shall, at any time, terminate the agency of any Authorized Agent by giving written notice of termination to such Authorized Agent and to the Trustee. Upon the resignation or termination of an Authorized Agent or in case at any time any such Authorized #30122041.1 48 Agent shall cease to be eligible under this Section (when, in either case, no other Authorized Agent performing the functions of such Authorized Agent shall have been appointed), the Company shall promptly appoint one or more qualified successor Authorized Agents approved by the Trustee and each Lessor to perform the functions of the Authorized Agent which has resigned or whose agency has been terminated or who shall have ceased to be eligible under this Section. The Company shall give written notice of any such appointment to all Holders as their names and addresses appear on the Security Register. ARTICLE II.

PNM will furnish or cause to be furnished to the Trustee semiannually, between January 15 and January 30, inclusive, and between July 15 and July 30, inclusive, in each year, and at such other times as the Trustee may request in writing, within 30 days after receipt by PNM of any such request, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders of Securities, in each case as of a date not more than 15 days prior to the time such list is furnished; provided, however, that so long as the Trustee is the sole Security Registrar, no such list need be furnished for so long as a copy of the Security Register is being furnished to the Trustee pursuant to Section 9.14(b). SECTION 1.002. Preservation of Information; Communications to Securityholders. (a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders of Securities contained in the most recent list furnished to the Trustee as provided in Section 9.14(b) or Section 10.01, as the case may be, and the names and addresses of Holders of Securities received by the Trustee in its capacity as Security Registrar, if so acting. The Trustee may destroy any list furnished to it as provided in Section 9.14(b) or Section 10.01, as the case may be, upon receipt of a new list so furnished. (b) If three or more Holders of Securities (hereinafter referred to as "applicants") apply in writing to the Trustee, and furnish to the Trustee reasonable proof that each such applicant has owned a Security for a period of at least six months preceding the date of such application, and such application states that the applicants desire to communicate with other Holders of Securities with respect to their rights under this Indenture or under the Securities and is accompanied by a copy of the form of proxy or other communication which such applicants propose to transmit, then the Trustee shall, within 5 Business Days after the receipt of such application, at its election, either: (i) afford such applicants access to the information preserved at the time by the Trustee in accordance with Section 10.02(a), or (ii) inform such applicants as to the approximate number of Holders of Securities whose names and addresses appear in the information preserved at the time by the Trustee in accordance with Section 10.02(a), and as to the approximate cost of mailing to such Securityholders the form of proxy or other communication, if any, specified in such application.

As provided in, and subject to the provisions of, the Indenture, Bonds of a particular Stated Maturity of principal are exchangeable for other Bonds of such Stated Maturity, but of a different authorized denomination or denominations, as requested by the Holder surrendering the same. No service charge will be made to any Holder of Bonds for any such transfer or exchange, but the Bond Registrar may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior to due presentment for registration of transfer, the person in whose name this Bond is registered shall be deemed to be the owner hereof for the purpose of receiving payment as herein provided and for all other purposes whether or not this Bond be overdue, regardless of any notice to anyone to the contrary. #30122043.1 5 As provided in the Indenture, the Indenture and the Bonds shall be construed in accordance with and governed by the laws of the State of New York.

The principal amount of Bonds with a Stated Maturity of principal of January 15, 2016 to be redeemed through operation of the Sinking Fund for such Bonds may be adjusted (upward or downward) at the discretion of the Company at one time prior to July 15, 1997; provided, however, that no such adjustment shall be made by the Company which will increase or reduce the average life of such Bonds (calculated in accordance with generally accepted financial practice from the date of initial issuance) by more than two years; provided further, however, such adjustment may only be made in connection with an adjustment to basic rent pursuant to Section 3(d) of one or more of the Leases identified in Schedule 2 hereto or related to the Lessor Notes described in Schedule 3 hereto. If the Company shall elect to make the foregoing adjustment, the Company shall deliver to the Trustee and PNM at least 60 days prior to the first Sinking Fund Date proposed to be affected by such adjustment, a Company Request (w) stating that the Company has elected to make such adjustment in connection with adjustments to basic rent under one or more of such Leases, (x) setting forth a revised schedule of principal amounts of the Sinking Fund applicable to such Bonds, (y) attaching a copy of the revised schedules of principal amortization for the related Pledged Lessor Notes (as defined in Article II of this Series 1986B Bond Supplemental Indenture and identified in Schedules 2 and 3 hereto) and (z) attaching calculations showing that (i) the average life of such Bonds will not be reduced or increased except as permitted by this paragraph (c), (ii) the aggregate principal amount of the Pledged Lessor Notes equals the aggregate principal amount of the Bonds and (iii) the aggregate amortization of the principal amount of such Pledged Lessor Notes is sufficient to repay in full, as and when due, the principal amount of such Bonds as and when due, whether upon redemption through operation of the applicable Sinking Fund or at maturity. The Trustee may rely on such Company Request and shall have no duty with respect to the calculations referred to in the foregoing clause (z) other than to make them available for inspection by any Holder of such Bonds at the Corporate Trust Office upon reasonable notice. The Trustee shall, at the expense of PNM, send to each Holder of such Bonds at least 20 days before the first Sinking Fund Date to be affected thereby, by first class mail, a copy of such revised schedule of principal amounts of Sinking Fund payments applicable to such Bonds. (d) Mandatory Adjustment to Sinking Funds. The second paragraph of Section 7.01 of the Original Indenture to the contrary notwithstanding, in the event that there shall have been any partial redemption of Bonds of a particular Stated Maturity of principal (other than pursuant to the Sinking Fund), the Sinking Fund payments thereafter to be made with respect to such Bonds shall be adjusted as follows. The Company shall first identify all related Pledged Lessor Notes (as defined in Article II of this Series 1986B Bond Supplemental Indenture and identified in Schedules 2 and 3 hereto) having the same maturity as the Bonds of such particular Stated Maturity of principal redeemed, #30122046.1 9 if any, which are outstanding following such redemption provided, however, that for purposes of this Section 1.04(d), any such Pledged Lessor Notes with a maturity subsequent to January 15, 2010 shall be deemed to have a maturity of January 15, 2016. Having identified all such outstanding Pledged Lessor Notes (the Outstanding Notes), the Company shall determine the dates on which the principal of such Outstanding Notes is to be amortized (the Scheduled Amortization Dates). The amount of the Sinking Fund payment scheduled to be made on each Sinking Fund Date subsequent to the date of such partial redemption shall then be adjusted to equal the aggregate principal amount of all Outstanding Notes scheduled to be amortized on the Scheduled Amortization Date corresponding to such Sinking Fund Date. All such adjustments in respect of Sinking Fund payments on a Sinking Fund Date shall be rounded to the nearest $1,000, and shall be subject to necessary further adjustment so that the total amount of such reduction is at least equal to the total principal amount of Bonds redeemed pursuant to such partial redemption. Having made the calculations required by the preceding two sentences, the Company shall deliver to the Trustee a Company Request not later than 30 days following any partial redemption of Bonds (other than pursuant to the Sinking Fund), setting forth (x) the schedules of principal amortization of all related Outstanding Notes having the same maturity as the Stated Maturity of principal of the Bonds redeemed and (y) a revised schedule of Sinking Fund payments applicable to Bonds having the same Stated Maturity of principal as the Bonds redeemed. The Trustee may rely on such Company Request and shall have no duty with respect to the adjustments set forth therein other than to make them available for inspection by a Holder of Bonds at the Corporate Trust Office upon reasonable notice. (e) Redemption Price. The Redemption Price for any Bond to be redeemed pursuant to Section 1.04(a) of this Series 1986B Bond Supplemental Indenture shall be 100% of the principal amount thereof, together with accrued interest to the Redemption Date. ARTICLE II. PLEDGE OF LESSOR NOTES SECTION 1.021. Pledge of Lessor Notes.

The Indenture and each of the Participation Agreements among an Equity Investor (as hereinafter defined), a Lessor (as hereinafter defined), the Company, the Lease Indenture Trustee (as hereinafter defined) and certain other parties (each a "Participation Agreement") provide (or, in the case of each of two of such Participation Agreements to be hereafter entered into as contemplated by the Indenture, will upon execution and delivery thereof provide) that, as and when issued, certain Nonrecourse Promissory Notes (the "Pledged Lessor Notes"), in the aggregate principal amount of $460,000,000, to be issued by The First National Bank of Boston, as owner trustee under one or more separate Trust Agreements, with the respective institutional investors named in such Trust Agreements (The First National Bank of Boston in each of such capacities as owner trustee being herein called a "Lessor" and each such institutional investor being herein called an "Equity Investor"), will be included within the assets subject to the lien of the Indenture pursuant to indenture supplements.

The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by PNM and the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Security issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Bond.

As provided in the Indenture, in connection with any mandatory sinking fund redemption of Bonds with a Stated Maturity of principal of January 15, 2016, the Company may cause the Trustee first to select for such redemption Bonds of such Stated Maturity of principal held by PNM or any Affiliate of PNM. In the event of any partial redemption of Bonds of a particular Stated Maturity of principal (other than pursuant to the aforementioned sinking fund), the principal amounts of Bonds of such Stated Maturity of principal to be redeemed thereafter pursuant to the sinking fund schedule indicated in the Indenture shall be adjusted in accordance with the Indenture. As provided in the Indenture, in the event that the Company shall fail to pledge certain Nonrecourse Promissory Notes included within the term "Pledged Lessor Notes" (the "Lessor Notes") in the aggregate principal amount of $88,000,000 (and otherwise as required by the Indenture), on or prior to January 25, 1987, Bonds will be redeemed as provided in the Indenture #30122046.1 4 (allocated among the Stated Maturities of principal of the Bonds as provided in the Indenture) in the aggregate amount equal to the difference between $88,000,000 and the principal amount of such Lessor Notes so pledged (if any), at a redemption price equal to 101% of the principal amount thereof, plus accrued interest thereon to the date fixed for redemption.

The Indenture provides that Bonds of a denomination larger than $1,000 may be redeemed in part ($1,000 or an integral multiple thereof) and that upon any partial redemption of any such Bond the same shall be surrendered at the corporate trust office of the Paying Agent in exchange for one or more new Bonds for the unredeemed portion thereof. Bonds (or portions thereof as aforesaid) for whose redemption and payment provision is made in accordance with the Indenture shall thereupon cease to be entitled to the lien of the Indenture and shall cease to bear interest from and after the date fixed for redemption. If an Event of Default, as defined in the Indenture, shall occur, the principal of this Bond may become or be declared due and payable, in the manner and with the effect provided in the Indenture. This Bond is transferable by the registered owner hereof in person or by attorney authorized in writing, at the corporate trust office of the Bond Registrar, Chemical Bank (or if such office is not in the Borough of Manhattan, The City of New York, at either such office or an office to be maintained in such Borough), upon surrender of this Bond, and upon any such transfer a new Bond of the same Stated Maturity of principal, for the same aggregate principal amount, will be issued to the transferee in exchange herefor. The Bonds are issuable only as registered Bonds without coupons in denominations of $1,000 and/or any integral multiple thereof. As provided in, and subject to the provisions of, the Indenture, Bonds of a particular Stated Maturity of principal are exchangeable for other Bonds of such Stated Maturity, but of a different authorized denomination or denominations, as requested by the Holder surrendering the same. No service charge will be made to any Holder of Bonds for any such transfer or exchange, but the Bond Registrar may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior to due presentment for registration of transfer, the person in whose name this Bond is registered shall be deemed to be the owner hereof for the purpose of receiving payment as herein provided and for all other purposes whether or not this Bond be overdue, regardless of any notice to anyone to the contrary.
