Recent Developments: Delay in Retail Restructuring

    In April 1999 New Mexico enacted the Electric Industry Restructuring Act of 1999 (the "Restructuring Act"). Pursuant to authority delegated by the Restructuring Act, the New Mexico Public Regulation Commission extended the deadline for implementation of customer choice service in New Mexico from January 1, 2001 to January 1, 2002. In March 2001, the Governor of New Mexico signed into law a five-year delay for the implementation of customer choice. Customer choice is now scheduled for implementation in New Mexico beginning in January 2007.

The CompanyTexas Electric Choice Act (the "Act") was enacted in June 1999, mandating full retail competition in Texas on January 1, 2002. Provisions were included in the Act to deal specifically with our company, recognizing that transmission constraints and PSCo will maintain their separate identities and continuemarket power concerns required a more structured schedule to serve customersopening our service area to customer choice. In the recent 2001 legislative session, additional changes were made to the provisions relating to us to actually defer competition in their respectiveour service areas.

General

    We may issue the Company has no Preferred Stock issued or outstanding. The New Preferred Stock may be issuedDebt Securities in one or more series, with such designations or titles; any voting powers; dividend rates and dates of payment; whether of not dividends shall be cumulative and, if cumulative, the date or dates from which dividends shall be cumulative; any redemption provisions, special or relative rights in the event of liquidation, disso- lution, distribution or winding up of the Company; any sinking fund provisions; any conversion provisions; and any other pref- erences, privileges, powers, rights, qualifications, limita- tions and restrictions, as shall be set forth as and when established by the Board of Directors of the Company and not inconsistent with applicable law or the Articles. The shares of any series of New Preferred Stock will be, when issued, fully paid and non-assessable and holders thereof will have no preemptive rights in connection therewith. The liquidation preference of any series of New Pre- ferred Stock is not necessarily indicative of the price at which shares of such series of New Preferred Stock will actu- ally trade at or after the time of their issuance. The market price of the shares of any series of New Preferred Stock can be expected to fluctuate with changes in market and economic con- ditions, the financial condition and prospects of the Company, and other factors that generally influence the market price of securities. Voting Rights Except as indicated in the Prospectus Supplement relating to a particular series of New Preferred Stock or except as expressly required by applicable law or the Articles, the holders of shares of New Preferred Stock will not have vot- ing rights. -7- The terms of the Preferred Stock may not be adversely changed without the consent of a majority in aggregate voting power of the Preferred Stock then outstanding or, if one or more but less than all of the shares thereof are so affected, a majority in aggregate voting power of the affected series vot- ing as one class. Dividend Rights Holders of each series of New Preferred Stock will be entitled to receive, when, as and if declared by the Board of Directors of the Company out of funds legally available there- fore, cash dividends at such rates (which may be variable or fixed, and if variable an index formula or other method may be used) and on such dates as are set forth in the Prospectus Sup- plement relating to such series of New Preferred Stock. Divi- dends will be payable to holders of record of New Preferred Stock as they appear on the books of the Company on such record dates as shall be fixed by the Board of Directors. Unless otherwise specified in the Prospectus Supplement relating to a series of New Preferred Stock, such dividends shall be payable from, and shall be cumulative from, the date of original issue of each share, so that if in any dividend period (being the period between such dividend payment dates) dividends at the rate or rates as described in the Prospectus Supplement relat- ing to such series of New Preferred Stock shall not have been declared and paid or set apart for payment on all outstanding shares of Preferred Stock for such dividend period and all pre- ceding dividend periods from and after the first day from which dividends are cumulative, then the aggregate deficiency shall be declared and fully paid or set apart for payment, but with- out interest, before any dividends shall be declared or paid or set apart for payment on the Common Stock by the Company. The cutting-off of dividends on Common Stock until the arrearages have been paid or provided for, as outlined above, and such rights, if any, to vote for the election of directors as may be set forth in the Prospectus Supplement relating to a series of New Preferred Stock, shall (unless otherwise set forth in the Prospectus Supplement) be the only consequences of the failure to declare or pay dividends on the New Preferred Stock. After payment in full of all dividend arrearages on the New Preferred Stock, dividends on the Common Stock may be declared and paid out of funds legally available for that purpose as the Board of Directors may determine. The Mortgage pursuant to which the Company's First Mortgage Bonds are issued contains a covenant limiting the -8- amount of dividends that the Company may declare on any stock, including Preferred Stock. (See "Description of New Bonds -- Dividend Covenant.") Redemption and Sinking Fund Provisions Any provisions relating to the redemption by the Com- pany or for a sinking fund or for redemption at the option of the holders of any series of New Preferred Stock will be as set forth in the Prospectus Supplement by which such New Preferred Stock is to be offered.

The New Preferred Stock may rank senior to, junior to, or on a parity with any other classes of equity securities issued by the Company, the terms of which specifically provide that such equity securities will rank junior to, senior to, or on parity with, such series of New Preferred Stock. Any provisions respecting the conditions or restric- tions upon the creation of indebtedness of the Company or upon the issuance of additional stock (including additional shares of such series or any other class) ranking on a parity with or senior to the New Preferred Stock as to dividends or distribu- tion of assets upon liquidation, dissolution, or winding up of the Company will be as set forth in the Prospectus Supplement. -9- Liquidation Rights In the event of liquidation, holders of the New Pre- ferred Stock may be entitled to receive, from assets available for distribution to stockholders, a preferential amount fixed for the respective series.

The provisions of this paragraph do not apply to redemptions pursuant to operation of any sinking fund (Mortgage, Articles 8 and 11). Sinking and Improvement Fund For each series of New Bonds for which the Company determines to provide a sinking and improvement fund, the terms of such fund will be described in the Prospectus Supplement relating to that series. -11- Security Each series of New Bonds together with all other Bonds heretofore or hereafter issuedissue under the Mortgage will be equally and ratably secured by the Mortgage, which constitutes, in the opinion of Hinkle, Cox, Eaton, Coffield & Hensley, L.L.P., counsel for the Company, a valid and direct first lien (subject to Permitted Encumbrances) on all the present proper- ties (principally generating plants and transmission and dis- tribution facilities) and franchises of the Company, other than Excepted Property, subject only to a reversionary interest in the site of the Company's generating plant near Borger, Texas, conditioned upon its continued use in the generation, transmis- sion and distribution of electric energy, and to certain minor defects in the Company's title to the sites of certain of its transmission and distribution lines, substations and minor structures. Neither such reversionary interest nor such minor defects, in the opinion of such counsel, materially interferes with the use or operation of the Company's properties. The Mortgage contains provisions for subjecting to the lien thereof (subject to limitations contained in Article 15 in case of a merger or transfer or lease of the Com- pany's assets) after-acquired property other than Excepted Property. After-acquired property may, subject to certain lim- itations, be subject to prior liens (Mortgage Section 9.15), but, if so subject, may not be included in Gross Bondable Additions or Net Bondable Additions under the Mortgage until the prior liens thereon have been paid or prepaid (Mortgage Section 4.01). Maintenance Covenant The Mortgage provides that the Company shall, on or before October 1 in each year, deposit with the Trustee cash equal to the excess of (i) 15% of operating revenues for the year ended the preceding May 31 (less the cost of utility ser- vices purchased for resale and a further sum equal to the cost of fuel used to generate electricity in excess of 2.90 mills per net kilowatt hour) with certain adjustments, over (ii) the amounts charged on its books for maintenance and repairs during such year. Instead of depositing cash, the Company may (a) deliver Bonds or certify that Bonds have been or are to be retired (with certain exceptions) or (b) certify Gross Bondable Additions. Cash so deposited may be withdrawn in the same man- ner as cash deposited on release of property, may be applied to the purchase of Bonds, or may be applied to the redemption of Bonds (Mortgage Section 9.06; Supplemental Indenture Section 1.02; -12- Mortgage, Article 8). Cash, Bonds and Gross Bondable Additions used to satisfy the requirements of the Maintenance Covenant may be deducted from Retirements in computing Net Bondable Additions (Mortgage Section 4.01). Issuance of Additional Bonds The maximum principal amount of Bonds which may be outstanding under the Mortgage at any one time is $3,000,000,000. The Mortgage provides that Bonds may be issued from time to time against (1) 60% of Net Bondable Additions (Mortgage, Article 4), (2) Bonds retired or then to be retired (with certain exceptions) (Mortgage, Article 6) or (3) cash deposited with the Bond Trustee for such purpose, which cash may be withdrawn from time to time against 60% of Net Bondable Additions (Mortgage, Article 5). With certain exceptions in the case of (2) above, no additional Bonds may be issued unless Net Earnings for 12 consecutive calendar months within the 15 immediately preceding calendar months, before interest and income and profits taxes, are at least twice the annual inter- est requirements on all Bonds outstanding and then to be issued and on all prior lien indebtedness. Based on the Company's financial results for the twelve months ended August 31, 1995, the Company could have issued approximately $316,330,000 prin- cipal amount of additional Bonds under this restriction. The available amount of Net Bondable Additions and Retired Bonds at August 31, 1995 was approximately $335,000,000 and $115,300,000 respectively. Dividend Covenant The Mortgage provides that the Company will not declare any dividends (other than dividends payable in its stock) upon any shares of its stock, or make any payment on account of the purchase, redemption or other retirement of, or any distribution in respect of, any shares of its stock except to the extent that the sum of (1) $1,278,243.59, (2) Net Income of the Company, as defined, since June 1, 1946, and (3) net proceeds received by the Company from the issue since such date of any shares of its stock (but only up to an amount equal to the aggregate amount of all payments since such date on account of the acquisition of any shares of its stock), shall be greater than the aggregate amount of dividends declared on all classes of the Company's stock and of all payments made on account of the acquisition of, or distribution in respect of, any shares of its stock since such date (Mortgage Section 9.20). At August 31, 1995, approximately $949,000 of the Company's -13- retained earnings of $378,458,000 was not available for any such purpose under this limitation. As a result of the redemption and repurchase of all of the then-outstanding Preferred Stock of the Comany in December 1995 and January 1996, an additional $6,254,843 of retained earnings is also not available. Modification of the Mortgage The Mortgage, the rights and obligations of the Com- pany and the rights of the Bondholders may be modified with the consent of the holders of 66-2/3% of the Bonds, and, if less than all series of Bonds are affected, the consent of the hold- ers of 66-2/3% of the Bonds of each series affected (Mortgage Section 19.06). No modification of the terms of payment of princi- pal, interest or premium and no modification reducing the per- centage required for modification is effective against any Bondholder without his consent. The Company has reserved the right to amend the Mort- gage without any consent or other action by holders of any series of Bonds created after July 15, 1992, including the New Bonds, as shall be necessary in order to amend or delete in its entirety the maintenance covenant set forth in the Mortgage, and such covenant as amended by the Supplemental Indentures. (See "Description of New Bonds -- Maintenance Covenant.") Defaults An event of default is defined as: default in pay- ment of principal of any Bond; default for 30 days in payment of interest upon any Bond or of sinking or improvement fund installments in respect of any Bond; default under other cove- nants for 60 days after notice to the Company by the Trustee or holders of 10% of the Bonds; failure to discharge final money judgments within 60 days; certain events in bankruptcy, insol- vency, or reorganization; and certain assumptions of custody or control of the Company or its assets by governmental agencies. The Bond Trustee may withhold notice of default (except in pay- ment of principal, interest or sinking or improvement fund installments) if in its judgment it is in the interests of the Bondholders (Mortgage Section 13.01). Holders of a majority of the Bonds may require the Bond Trustee to, and holders of 25% of the Bonds may, declare the principal and interest due and payable on default, but holders of a majority of the Bonds may annul such declaration if such default is cured (Mortgage Section 13.01). No Bondholder may enforce the Mortgage unless such holder shall have given the Bond Trustee written notice of a default and unless the holders of a majority of the Bonds have requested the Bond Trustee in -14- writing to act and have offered the Bond Trustee reasonable indemnity or security, if required, and the Bond Trustee shall have failed to act for a period of 30 days (Mortgage Section 13.14). The foregoing does not affect the right of each Bondholder to enforce payment of principal and interest on the holder's Bond. Holders of a majority of the Bonds may direct the Bond Trustee to take action in the event of default (Mortgage Sections 13.04, 13.19). The Bond Trustee is not required to risk its funds or incur personal liability if there is reasonable ground for believing that repayment is not reasonably assured (Mortgage Section 16.02). Other than in connection with applications made under the Mortgage from time to time, periodic evidence is not required to be furnished as to absence of default or as to com- pliance with the terms of the Mortgage.limited. The Bond Trustee Chemical Bank is the Bond Trustee under the Mortgage.

BOOK-ENTRY SYSTEM

    Each series of Debt Securities offered by this prospectus may be issued initially in the form of one or more glo- balglobal securities underrepresenting all or part of that series of Debt Securities. This means that we will not issue certificates for that series of Debt Securities to the holders. Instead, a book-entryglobal security representing that series will be deposited with, or on behalf of, DTC, or its successor as the Depository and registered in the name of the Depository or a nominee of the Depository.

    The Depository will keep a computerized record of its participants (for example, your broker) whose clients have purchased the Debt Securities. Unless it is exchanged in whole or in part for a certificated security, a global security may not be transferred, except that the Depository, its nominees and their successors may transfer a global security as a whole to one another.

    Beneficial interests in global securities will be shown on, and transfers of interests will be made only system operatedthrough, records maintained by the Depository and its participants. The laws of some jurisdictions require that some purchasers take physical delivery of securities in definitive form. These laws may impair the ability to transfer beneficial interests in a securities depository.global security.

    We will wire principal, interest and any premium payments to the Depository or its nominee. We and the Trustee will treat the Depository or its nominee as the owner of the global security for all purposes, including any notices and voting. Accordingly, we, the Trustee and any paying agent will have no direct responsibility or liability to pay amounts due on a global security to owners of beneficial interests in a global security.

    Unless otherwise specified in the Pro- spectus Supplement, The Depository Trust Company ("DTC")prospectus supplement, DTC will act as securities depositoryDepository for the New Bonds and New Unse- curedthose Debt Securities which wouldissued as global securities. The Debt Securities will be registered in the name of Cede & Co., as registered securityholder and nominee for DTC. Indi- vidual purchases of Book-Entry Interests (as herein defined) in any such New Bonds or New Unsecured Securities will be made in book-entry form. Purchasers of Book-Entry Interests in such New Bonds or New Unsecured Securities will not receive certifi- cates representing their interests in such New Bonds or New Unsecured Securities. So long as Cede & Co., as nominee of DTC, is the securityholder, references herein to holders of the New Bonds or New Unsecured Securities or registered owners will mean Cede & Co., rather than the owners of Book-Entry Interests in New Bonds or New Unsecured Securities. (DTC's partnership nominee).

    DTC is a limited purposelimited-purpose trust company organized under the banking laws of the State of New York andBanking Law, a "banking organization" within the meaning of that law,the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clear- ing"clearing agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act.Act of 1934. DTC holds securities deposited bythat its participants (the "DTC("Direct Participants") anddeposit with DTC. DTC also facilitates the settlement among Direct Participants of securities transactions, among DTC Participantssuch as transfers and pledges, in -23- suchdeposited securities through electronic computerized book-entry changes in accounts of the DTC Participants, thereby eliminat- ingDirect Participants' accounts. This eliminates the need for physical movement of securities certificates. Direct DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations, someorganizations. DTC is owned by a number of whom (including, possibly, the under- writers with respect to the New Bonds or New Unsecured Securi- ties), together withits Direct Participants and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc.LLC, and the National Association of Securities Dealers, Inc., own DTC. Access to the DTC system is also available to others such as banks,securities brokers and dealers, banks, and trust companies that clear through or maintain a custodial relationship with a DTCDirect Participant, either directly or indi- rectly (the "Indirectindirectly ("Indirect Participants"). The rules that apply to DTC Participants purchasing Book-Entry Interests (as defined below) in any New Bonds or New Unsecured Securities will not receive certificates. Each DTC Participant will receive a credit balance in the records of DTC in the amount of such DTC Participant's interest in such New Bonds or New Unse- cured Securities, which will be confirmed in accordance with DTC's standard procedures. The ownership interest of each actual purchaser of a Book-Entry Interest in a New Bond or New Unsecured Security (the "Book-Entry Interests") will be recorded through the records of the DTC Participant or through the records of the Indirect Participant. Owners of Book-Entry Interests should receive from the DTC Participant or Indirect Participant a written confirmation of their purchase providing details of the Book-Entry Interests acquired. Transfers of Book-Entry Interests will be accomplished by book entries made by the DTC Participantsand its Direct or Indirect Participants who act(collectively, "Participants") are on behalffile with the SEC.

    It is DTC's current practice, upon receipt of the ownersany payment of Book-Entry Interests. Owners of Book-Entry Interests will not receive certificates representing their ownership of Book-Entry Interests with respect to any New Bondsprincipal or New Unsecured Securities except as described below upon the resignation of DTC. Under the Mortgage and Indenture, payments made by the Bond Trustee or the Unsecured Securities Trustee (collec- tively, the "Trustees" and individually, the "Trustee") to DTC or its nominee will satisfy the Company's obligations under the Mortgage or Indenture, as the case may be, to the extent of the payments so made. Owners of Book-Entry Interests will not be or be considered by the Company or the respective Trustee to be, and will not have any rights as, holders of New Bonds under the Mortgage or New Unsecured Securities under the Indenture, as the case may be. -24- NEITHER THE COMPANY NOR ANY TRUSTEE UNDER THE MORT- GAGE AND INDENTURE WILL HAVE ANY RESPONSIBILITY OR OBLIGATION TO ANY DTC PARTICIPANT, INDIRECT PARTICIPANT OR ANY OWNER OF A BOOK-ENTRY INTEREST OR ANY OTHER PERSON NOT SHOWN ON THE REGIS- TRATION BOOKS OF SUCH TRUSTEE AS BEING A HOLDER OF NEW BONDS OR NEW UNSECURED SECURITIES WITH RESPECT TO: (1) ANY NEW BONDS OR NEW UNSECURED SECURITIES, AS THE CASE MAY BE; (2) THE ACCURACY OF ANY RECORDS MAINTAINED BY DTC OR ANY DTC PARTICIPANT OR INDIRECT PARTICIPANT; (3) THE PAYMENT BY DTC OR ANY DTC PAR- TICIPANT OR INDIRECT PARTICIPANT OF ANY AMOUNT DUE TO ANY OWNER OF A BOOK-ENTRY INTEREST IN RESPECT OF THE PRINCIPAL OR REDEMP- TION PRICE OF OR INTEREST ON SUCH NEW BONDS OR NEW UNSECURED SECURITIES; (4) THE DELIVERY BY DTC OR ANY DTC PARTICIPANT OR INDIRECT PARTICIPANT OF ANY NOTICE TO ANY OWNER OF A BOOK-ENTRY INTEREST WHICH IS REQUIRED OR PERMITTED UNDER THE TERMS OF THE MORTGAGE OR INDENTURE TO BE GIVEN TO HOLDERS OF NEW BONDS OR NEW UNSECURED SECURITIES; (5) THE SELECTION OF THE OWNERS OF A BOOK-ENTRY INTEREST TO RECEIVE PAYMENT IN THE EVENT OF ANY PAR- TIAL REDEMPTION OF ANY NEW BONDS OR NEW UNSECURED SECURITIES; OR (6) ANY CONSENT GIVEN OR OTHER ACTION TAKEN BY DTC OR ITS NOMINEE AS HOLDER OF NEW BONDS OR NEW UNSECURED SECURITIES. Principal and redemption price of, and interest, pay- ments on, New Bonds and New Unsecured Securities registered in the name of DTC or its nominee will be made to DTC or such nom- inee, as registered owner of such New Bonds or New Unsecured Securities. DTC is responsible for disbursing such payments to the appropriate DTC Participants and such DTC Participants, and any Indirect Participants, are in turn responsible for disburs- ing the same to the owners of Book-Entry Interests. Unless it has reason to believe it will not receive payment, DTC's cur- rent practice is to credit theDirect Participants' accounts ofon the DTC Participants on a payment date in accordance withaccording to their respective holdings of beneficial interests in the global security as shown on the records of DTC.DTC's records. In addition, it is DTC's current practice to assign any consenting or voting rights to Direct Participants whose accounts are credited with securities on a record date, by using an omnibus proxy. Payments by DTC Participants and Indirect Participants to owners of Book-Entry Interestsbeneficial interests in a global security, and voting by Participants, will be governed by the standing instructions and customary practices between the participants and owners of beneficial interests, as is now the case with securities held for the accountsaccount of cus- tomers in bearer form orcustomers registered in "street name", andname." However, payments will be the responsibility of such DTC Participant or Indirect Par- ticipantthe Participants and not our responsibility or that of DTC the Company or the respective Trustee, subject to any statutory and regulatory requirements as may be in effect from time to time.

Each person for whom a DTC Participant or Indirect Participant acquires an interest in New Bonds or New Unsecured Securities, as nominee, may desire to make arrangements with such DTC Par- ticipant or Indirect Participant to receive a credit balance in the records of such DTC Participant or Indirect Participant, to have all notices of redemption or other communications to or by DTC which may affect such persons forwarded in writing by such DTC Participant or Indirect Participant, and to have notifica- tion made of all debt service payments. Purchases, transfers and sales of Book-Entry Inter- ests by the ultimate Book-Entry Interest owners may be made through book entries made by DTC Participants or Indirect Par- ticipants or others who act for the ultimate Book-Entry Inter- est owner. The Bonds Trustee, the Unsecured Securities Trus- tee, the Company and the underwriters, as such, have no role in those purchases, transfers or sales. Owners of Book-Entry Interests may be charged a sum sufficient to cover any tax, fee, or other governmental charge that may be imposed in relation to any transfer or exchange of a Book-Entry Interest. Each Trustee will recognize and treat DTC (or any successorcertificated securities depository) or its nominee as the holder of New Bonds and New Unsecured Securities registered in its name or the name of its nominee for all purposes, including payment of debt service, notices, enforcement of remedies and voting. Under DTC's current practice, a proxy will be given to the DTC Participants holding Book-Entry Interests in New Bonds and New Unsecured Securities in connection with any matter on which holders of such New Bonds or New Unsecured Securities are asked to vote or give their consent. Crediting of debt service payments and transmittal of notices and other communications by DTC to DTC Participants, by DTC Participants to Indirect Par- ticipants and by DTC Participants and Indirect Participants to the ultimate Book-Entry Interest owners are the responsibility of those persons and will be handled by arrangements among them and are not the responsibility of either Trustee, the Company or any underwriter, as such. Each Trustee, so long as a book-entry system is used for any series of New Bonds or New Unsecured Securities, will send any notice of redemption and any other notices required by the Mortgage or Indenture to be sent to holders of such New -26- Bonds or New Unsecured Securities, respectively, only to DTC (or such successor securities depository) or its nominee. Any failure of DTC to advise any DTC Participant, or of any DTC Participant or Indirect Participant to notify the Book-Entry Interest owner, of any such notice and its content or effect will not affect the validity of the redemption of the New Bonds or New Unsecured Securities called for redemption, or any other action premised on that notice. In the event of a call for redemption, the Trustee's notification to DTC will initiate DTC's standard call process, and, in the event of a partial call, its lottery process by which the call will be randomly allocated to DTC Participants holding positions in the New Bonds or New Unsecured Securities to be redeemed. When DTC and DTC Participants allocate the call for redemption, the owners of the Book-Entry Interests that have been called should be notified by the broker or other person responsible for main- taining the records of those interests and subsequently cred- ited by that person with the proceeds once such New Bonds or New Unsecured Securities are redeemed. The Company, the Bond Trustee, the Unsecured Securi- ties Trustee and any underwriter or agent cannot and do not give any assurancessame terms in authorized denominations only if:

    The information in exchangethis section concerning DTC and DTC's book-entry system has been obtained from DTC, and we and any underwriters, dealers or agents take no responsibility for the New Bondsaccuracy thereof.

    Any underwriters, dealers or New Unsecuredagents of any Debt Securities heldmay be Direct Participants of DTC.
