                              PNM RESOURCES, INC.
                                PNM DIRECT PLAN
                                 COMMON STOCK
                                (NO PAR VALUE)

                             --------------------

    This prospectus relates to shares of common stock, no par value, of PNM
Resources, Inc. that may be offered in connection with the PNM Resources, Inc.
PNM Direct Plan. The plan replaces and assumes the Public Service Company of
New Mexico PNM Direct Plan, or the original plan, initially established on
August 28, 1996 by PNM Resources's wholly owned subsidiary, Public Service
Company of New Mexico. On December 31, 2001, PNM Resources became the parent
of Public Service Company of New Mexico, or PNM, pursuant to a one-for-one
exchange of common stock between the two corporations.

    The plan is designed to provide investors with a convenient way to purchase
shares of PNM Resources common stock, and to reinvest all or a portion of the
cash dividends paid on PNM Resources common stock in additional shares of common
stock.

         PARTICIPANTS IN THE PLAN MAY:

         - Reinvest all or a portion of cash dividends paid on common stock
           registered in their names or on common stock credited to their plan
           accounts in shares of common stock.

         - Make an initial investment in common stock with a cash payment of at
           least $50, and additional optional investments thereafter of at least
           $50, up to a maximum of $60,000 per calendar year, including the
           initial investment; provided, however, that employees of PNM
           Resources and any of its affiliates who elect to invest through
           payroll deductions may make an initial investment of at least $25,
           and additional optional investments thereafter of at least $25.

         - Make investments, including initial investments, in the plan by
           electronic funds deduction from financial institution accounts.

         - Make investments in common stock during two separate investment
           periods in each month and not just one investment period per month,
           as provided for under the original plan.

         - Receive, upon written request, certificates for whole shares of
           common stock credited to their plan accounts.

         - Deposit certificates representing common stock into the plan for
           safekeeping.

         - Sell shares of common stock credited to their plan accounts through
           the plan.

    Shares of common stock will be purchased under the plan, at the option of
PNM Resources, from newly issued shares, shares held in the treasury of PNM
Resources not reserved for any other purposes or shares purchased on the open
market. Purchases will be effected through an independent agent appointed by PNM
Resources. The common stock is listed on the New York Stock Exchange under the
ticker symbol PNM.

    To the extent required by applicable law in certain jurisdictions, shares of
common stock offered under the plan to persons not presently record holders of
common stock are offered only through a registered broker/dealer in such
jurisdictions.

    This prospectus contains a summary of the material provisions of the plan
and, therefore, this prospectus should be retained by participants in the plan
for future reference.

                              PNM RESOURCES, INC.

    PNM Resources, Inc. was incorporated on March 3, 2000 under the laws of
the State of New Mexico and became the holding company for PNM on December 31,
2001, the date of effectiveness of a share exchange between PNM Resources and
PNM approved by PNM's shareholders on June 6, 2000. As a result of the share
exchange, PNM became a direct wholly-owned subsidiary of PNM Resources and
each share of common stock of PNM, including each share previously issued
under the original plan, was exchanged for one share of common stock of PNM
Resources. At the effective time of the share exchange, the original plan was
replaced and assumed by PNM Resources, with PNM Resources common stock used in
lieu of common stock of PNM whenever after that time stock is to be issued
under the plan. Otherwise, all accounts and all elections, notices,
instructions and authorizations under the original plan automatically continue
under, and all participants in the original plan automatically continue as
participants in, the plan.

    PNM is a public utility primarily engaged in the generation, transmission,
distribution, sale and trading of electricity and in the transmission,
distribution and sale of natural gas. The principal executive offices of PNM
Resources and PNM are located at Alvarado Square, Albuquerque, New Mexico 87158,

PURPOSE OF THE PLAN

1.  WHAT IS THE PURPOSE OF THE PLAN?

    The purpose of the plan is to provide shareholders and interested investors
    with a convenient and economical way to purchase shares of common stock with
    cash investments (including an initial cash investment) or reinvested
    dividends.

ADVANTAGES AND DISADVANTAGES OF THE PLAN

2.  WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF THE PLAN?

    THE PLAN OFFERS INVESTORS THE FOLLOWING ADVANTAGES:

    A. Direct Purchase of Stock--Persons not presently owning shares of common
       stock may become shareholders of PNM Resources by making an initial cash
       investment of at least $50, or if you are an employee of PNM Resources or
       any of its affiliates, by making an initial cash investment by payroll
       deduction of at least $25 (but not more than $60,000 per account per
       calendar year). See Question 5.

       Participants may invest additional funds at any time to purchase shares
       of common stock. The maximum annual cash investment (including the
       initial cash investment) is $60,000 per account.

    B. Sell Stock--Participants may sell shares held in their plan account
       through the plan. See Questions 32 and 33.


                                        4


    C. Certificate Safekeeping--Participants may deposit their common stock
       certificates with PNM Resources, whether or not the common stock
       represented by such certificates was purchased through the plan, and have
       their ownership maintained on PNM Resources's records in their plan
       account. This convenience is provided at no cost to the participant and
       eliminates the possibility of loss, inadvertent destruction, or theft of
       certificates. Also, because shares deposited for safekeeping are treated
       in the same manner as shares purchased through the plan, they may be
       transferred or sold through the plan. See Question 31.

    D. Reinvestment of Dividends--All or a portion of common stock dividends may
       be reinvested to purchase additional shares of common stock. See
       Questions 7 through 9.

    E. Simplified Recordkeeping--An investment statement will be mailed to a
       participant after an investment period in which the participant's account
       had investment activity. The statement is cumulative, providing
       year-to-date plan account activity. A plan history statement will be sent
       when shares are sold, transferred or otherwise withdrawn from the plan.
       See Questions 34 and 37.

    F. Reduced Broker Commissions--The broker commissions negotiated by PNM
       Resources for buying or selling shares are typically substantially less
       than those paid by individual investors for this service. No commissions
       are paid for newly issued shares or treasury shares. See Questions 27 and
       33.

    G. Transfer of Shares--Participants may transfer shares held in their plan
       account to another individual's account at no cost. The normal transfer
       requirements will apply. See Questions 30 and 43.

    H. Full Investment of Funds--The full amount of reinvested dividends and
       cash investments can be invested because the plan permits fractional
       shares to be credited to plan accounts. Dividends are paid on fractional
       shares as well as on whole shares. See Question 28.

    PLAN PARTICIPATION PRESENTS INVESTORS WITH THE FOLLOWING DISADVANTAGES:

    A. No Interest on Funds Pending Investment--No interest is paid on dividends
       or cash investments held pending investment or reinvestment. See Question
       17.

    B. Delay in Determining Purchase Price--The number of shares purchased for
       an investor's plan account will not be determined until all shares for
       the relevant investment period have been purchased. Therefore, investors
       will not know the number of shares purchased or the purchase price until
       the investment date. See Questions 25 through 29.

    C. Return of Cash Investments on Request--Cash investments (including
       initial cash investments) sent to the plan administrator will not be
       returned to the investor unless a written request is received by the plan
       administrator by the last business day prior to the relevant investment
       period. See Question 19.

    D. Periodic Delays for Issuing Certificates or Selling Shares--Requests for
       issuance of certificates or the sale of shares from a plan account will
       be delayed during the dividend processing period. This is a 13-15
       business day period which begins on the ex-dividend date. See Questions
       30, 33, and 34.

    E. Broker Commissions--While the broker commissions negotiated by the plan
       administrator for buying or selling stock are typically less than those
       paid by individual investors for this service, certain investors may be
       able to negotiate lower commissions on an individual basis. Also, the
       commissions negotiated by the plan administrator may change from time to
       time. See Questions 27 and 33.

    F. Price of Shares--Plan participants cannot designate a specific price at
       which to sell or purchase common stock. Requests for the sale of plan
       shares are accumulated and the plan administrator places a market order
       with the appointed agent. Similarly, a market order is placed with the
       independent agent to purchase stock with all funds available for
       investment. See Questions 24, 27, and 32.


                                        5

PARTICIPATION IN THE PLAN

4.  WHO IS ELIGIBLE TO PARTICIPATE IN THE PLAN?

    Any interested investors making the applicable minimum initial cash
    investment and all common stock shareholders of record are eligible to
    participate. Citizens or residents of a country other than the United
    States or its territories and possessions should determine whether they
    are subject to any governmental regulations prohibiting or restricting
    participation in the plan, and must provide evidence satisfactory to the
    administrator that their participation will not violate any such
    regulations, before enrolling in the plan.

    Beneficial owners of common stock whose shares are held in a name other
    than their own (for example, a bank, broker, or trustee) may participate
    in the plan with respect to such shares by transferring those shares into
    their own name.

5.  HOW DOES AN ELIGIBLE INVESTOR ENROLL IN THE PLAN?

    After being furnished with a plan prospectus, eligible investors may join
    the plan by completing and signing an enrollment form and returning it to
    PNM Resources. Non-shareholder investors must submit an initial cash
    investment of at least $50 (but not more than $60,000 per account per
    calendar year). Non-shareholder investors who are also employees of PNM
    Resources or any of its affiliates and who elect to invest through a
    payroll deduction must submit an initial cash investment of at least $25.
    Once enrolled in the plan, eligible investors will remain enrolled until
    they discontinue their participation or the plan is terminated. See
    Questions 34, 35 and 41.

6.  WHEN MAY AN ELIGIBLE INVESTOR JOIN THE PLAN?

    An eligible investor may join the plan at any time by completing and
    returning an enrollment form.

PARTICIPATION OPTIONS

7.  WHAT PARTICIPATION OPTIONS ARE AVAILABLE IN THE PLAN?

    On the enrollment form, the investor is offered the following
    participation options:

      --Full Dividend Reinvestment
      --Partial Dividend Reinvestment or
      --Cash Investment Only


                                        6


8.  HOW DOES THE "FULL DIVIDEND REINVESTMENT" OPTION OF THE PLAN WORK?

    Participants enrolling in the "Full Dividend Reinvestment" option will
    have dividends earned on all common stock, both in their plan account and
    of record, reinvested to purchase additional shares of common stock. The
    reinvestment of dividends will commence with the first dividend to which
    the participant is entitled payable after the next dividend record date
    following enrollment. A participant may also make cash investments of up
    to $60,000 per account annually to purchase common stock.

9.  HOW DOES THE "PARTIAL DIVIDEND REINVESTMENT" OPTION OF THE PLAN WORK?

    Participants enrolling in the "Partial Dividend Reinvestment" option can
    designate a specific number of shares on which they wish to receive cash
    dividends, with dividends on the balance of shares being reinvested to
    purchase common stock. Participants may also elect to receive cash
    dividends on shares they hold in certificate form, with dividends on
    shares held in their plan account being reinvested. The reinvestment of
    dividends will commence with the first dividend to which the participant
    is entitled payable after the next dividend record date following
    enrollment. In addition, a participant may make cash investments of up to
    $60,000 per account annually to purchase common stock.

    If a participant has elected this option and subsequently directs that a
    portion of his or her shares are to be sold, transferred, or withdrawn,
    unless the participant otherwise directs, all shares on which a
    participant receives reinvested dividends will be sold, transferred, or
    withdrawn prior to the sale, transfer, or withdrawal of any shares on
    which a participant receives cash dividends.

10. HOW DOES THE "CASH INVESTMENT ONLY" OPTION OF THE PLAN WORK?

    Participants enrolling in the "Cash Investment Only" option may make cash
    investments of at least $50, but not more than $60,000 per account
    annually. Participants who are also employees of PNM Resources or any of
    its affiliates and who elect to use payroll deductions may make cash
    investments of at least $25. Dividends earned on all common stock, both
    in the plan account and of record, will be paid directly to the investor
    in the manner in which dividends are normally paid. The cash investment
    will purchase additional shares of common stock.

    NOTE: IF PARTICIPANTS DO NOT INDICATE A PARTICIPATION OPTION ON THE
    ENROLLMENT FORM, THEIR ACCOUNT WILL AUTOMATICALLY BE ENROLLED INTO THE
    "FULL DIVIDEND REINVESTMENT" OPTION.

11. MAY PARTICIPANTS CHANGE THEIR PARTICIPATION OPTION?

    Yes. The participation option may be changed by completing and signing a
    new enrollment form and returning it to PNM Resources. The change will be
    effective as of the next dividend record date following receipt of the
    new enrollment form.

12. MAY PNM RESOURCES RESTRICT PARTICIPATION IN THE PLAN?

    Yes. PNM Resources reserves the right to restrict participation in the
    plan if it believes that such participation may be contrary to the
    general intent of the plan or in violation of applicable law.

INITIAL CASH INVESTMENTS AND CASH INVESTMENTS

13. WHO IS ELIGIBLE TO MAKE CASH INVESTMENTS?

    Any shareholder of record who has submitted a signed enrollment form is
    eligible to make cash investments regardless of the participation option
    chosen, subject to the maximum contribution. See Question 16.

14. WHO IS ELIGIBLE TO MAKE AN INITIAL CASH INVESTMENT?

    Any interested investor may submit a signed enrollment form and make an
    initial cash investment, subject to the applicable minimum and maximum
    contributions. See Question 16.

                                        7


15. HOW ARE INITIAL CASH INVESTMENTS AND CASH INVESTMENTS MADE?

    Initial cash investments and subsequent cash investments must be made by
    check, money order, or electronic funds deduction from a U.S. bank or
    other U.S. financial institution, in U.S. dollars, to PNM
    Resources, Inc. PNM Direct Plan. DO NOT SEND CASH. Initial cash
    investments must be accompanied by a completed enrollment form; an
    enrollment form or a cash investment form should accompany subsequent
    cash investments to ensure credit to the proper account. An employee of
    PNM Resources or any of its affiliates may elect to make an initial cash
    investment or subsequent cash investments through payroll deductions by
    completing and returning a payroll deduction authorization form. PNM
    Resources also allows for cash investments to be made by electronic debit
    from a specified account by completing and returning an electronic debit
    authorization form.

16. IS THERE A MINIMUM AND MAXIMUM CASH INVESTMENT?

    Yes. Generally, the minimum initial cash investment is $50 and the
    minimum for subsequent cash investments is $50. However, if you are an
    employee of PNM Resources or any of its affiliates and you elect to
    invest through payroll deductions, the minimum initial cash investment is
    $25 and the minimum for subsequent cash investments is $25. The maximum
    aggregate cash investment (including the initial cash investment) is
    $60,000 per account per calendar year.

17. WHEN WILL A PARTICIPANT'S INITIAL CASH INVESTMENT OR SUBSEQUENT CASH
    INVESTMENT BE INVESTED?

    Initial cash investments and subsequent cash investments will be invested
    during the investment period immediately following the investment period
    during which the funds are received. Because interest is not paid on
    funds pending investment, it is to your benefit to mail your cash
    investments so they are received shortly before the end of an investment
    period. Funds are considered to be received when delivered, either by
    postal service or in person, during business hours to PNM Resources's
    corporate headquarters (see "Shareholder Information" below for address).

    In the event that a check submitted for investment is returned unpaid for
    any reason, the plan administrator will consider the request for
    investment of such funds null and void. Any shares purchased upon the
    prior credit of such funds will be immediately removed from the
    participant's account. The plan administrator will be entitled to sell
    those shares to satisfy any uncollected amounts. If the net proceeds of
    the sale of such shares are insufficient to satisfy the balance of such
    uncollected amounts, the plan administrator will be entitled to sell
    additional shares from the participant's account to satisfy the
    uncollected balance.

    NOTE: INTEREST IS NOT PAID ON FUNDS HELD PENDING INVESTMENT.

18. WHEN WILL SHARES PURCHASED WITH INITIAL CASH INVESTMENTS OR SUBSEQUENT
    CASH INVESTMENTS BE ENTITLED TO RECEIVE DIVIDENDS?

    Shares purchased with an initial cash investment or a subsequent cash
    investment will be entitled to dividends if the shares were credited to
    the participant's account as of a date preceding the dividend record date
    for payment of a dividend.

19. MAY A PARTICIPANT REQUEST THAT AN INITIAL CASH INVESTMENT OR SUBSEQUENT
    CASH INVESTMENT BE RETURNED?

    Yes. A participant may request, in writing, the return of an initial cash
    investment or a subsequent cash investment. The funds will be returned if
    the request is received by the last business day of PNM Resources prior
    to the relevant investment period.

                                        8


REINVESTMENT OF DIVIDENDS

20. IS THERE A MINIMUM OR MAXIMUM AMOUNT FOR REINVESTED DIVIDENDS?

    No. Dividends designated for reinvestment through the plan are not
    subject to a minimum or maximum.

21. WHEN WILL A PARTICIPANT'S DIVIDENDS BE REINVESTED?

    A participant's dividends will be reinvested during the investment period
    following the investment period in which the dividend is payable.

22. WHEN WILL SHARES PURCHASED WITH REINVESTED DIVIDENDS BE ENTITLED TO
    RECEIVE DIVIDENDS?

    Shares purchased with reinvested dividends will be entitled to dividends
    on the dividend payment date following the purchase of such shares.

PURCHASES

23. WHAT IS THE SOURCE OF COMMON STOCK PURCHASED THROUGH THE PLAN?

    Common stock purchased through the plan will be purchased, at the
    discretion of PNM Resources and in accordance with applicable law, either
    on the open market or directly from PNM Resources or through a
    combination of the foregoing. Shares purchased from PNM Resources may be
    either authorized but unissued shares or shares held in the treasury of
    PNM Resources not reserved for any other purpose or a combination of
    both. PNM Resources currently anticipates that shares will initially be
    purchased on the open market.

24. HOW IS COMMON STOCK PURCHASED ON THE OPEN MARKET?

    Common stock will be purchased through an independent agent appointed by
    PNM Resources. The independent agent will have full discretion in all
    matters related to such purchases, including the day and time of
    purchase, price paid, number of shares purchased and the markets or
    persons through whom the purchases are made.

25. WHEN ARE SHARES PURCHASED FOR THE PLAN?

    Purchases of shares on the open market may begin on the first day of the
    relevant investment period and will be completed no later than 15 days
    thereafter. Please see Questions 17 and 21 to determine the relevant
    investment period. Dividends not invested in common stock within 30 days
    of the dividend payment date therefor and cash investments not invested
    in common stock within 35 days of receipt will be promptly returned to
    participants.

    Shares purchased by the plan from PNM Resources (newly issued common
    stock or treasury shares) will be acquired as of the first day of the
    relevant investment period, provided that the New York Stock Exchange is
    open on such day. See Question 26.

26. WHEN WILL SHARES BE CREDITED TO A PARTICIPANT'S ACCOUNT?

    Participants' shares will be credited to their plan accounts on the
    investment date and are considered to be owned by the participant on that
    day. If the investment date falls on a date when the New York Stock
    Exchange is closed, the first day immediately succeeding such day on
    which the New York Stock Exchange is open will be the investment date.

                                        9


27. HOW IS THE PURCHASE PRICE OF THE COMMON STOCK DETERMINED?

    The purchase price of common stock purchased on the open market will be
    the weighted average price, including broker commissions, related service
    charges and applicable taxes, of all shares purchased during the
    investment period.

    The purchase price of common stock purchased from PNM Resources (newly
    issued common stock or treasury shares) will be the average of the high
    and low prices of the common stock reported on the New York Stock
    Exchange Composite Tape as published in The Wall Street Journal or, for
    any day on which there is no such publication, in another generally
    accepted publication for the first business day of the relevant
    investment period, provided that the New York Stock Exchange is open on
    such day.

    If the stock is purchased both on the open market and through PNM
    Resources, the purchase price will be the weighted average price of such
    shares in accordance with the foregoing two paragraphs.

28. HOW MANY SHARES OF COMMON STOCK WILL BE PURCHASED FOR A PARTICIPANT?

    The number of shares purchased for a participant will be equal to the
    participant's cash investments for the preceding investment period plus
    dividends available for reinvestment (see Question 21) divided by the
    purchase price of the shares. The participant's account will be credited
    with the whole and fractional shares on the investment date.

29. CAN A PARTICIPANT REQUEST THE PURCHASE OF A SPECIFIC NUMBER OF SHARES?

    No. Since the purchase price of the common stock cannot be calculated
    until the common stock is purchased, a participant may not purchase a
    specific number of shares.

CERTIFICATES

30. WILL CERTIFICATES BE ISSUED FOR SHARES PURCHASED THROUGH THE PLAN?

    No. The certificates for shares purchased through the plan are registered
    in the name of a nominee on behalf of plan participants. A certificate
    will be issued to participants only upon request.

    Participants requesting the issuance of a certificate for their plan
    shares should submit the request in writing to the plan administrator,
    specifying the number of shares to be issued. Certificates will generally
    be issued within five days following the receipt of the request. However,
    requests received during the dividend processing period will be delayed.
    See "Plan participation presents investors with the following
    disadvantages--D." Certificates cannot be issued for fractional shares.

    The certificate will be issued in the name(s) of the participant(s).
    Requests to issue a certificate into another registration must meet the
    requirements for transfer of stock. See Question 43.

    See Question 9 for information relating to the certification of only a
    portion of a participant's plan shares when the participant has elected
    the "Partial Dividend Reinvestment" option for his or her shares.

SAFEKEEPING OF CERTIFICATES

31. CAN CERTIFICATES BE RETURNED TO THE COMPANY TO BE HELD IN THE
    PARTICIPANT'S PLAN ACCOUNT?

    Yes. Certificates for common stock may be returned to the plan
    administrator to take advantage of the safekeeping feature of the plan.
    THE CERTIFICATES SHOULD NOT BE ENDORSED AND REGISTERED MAIL IS
    RECOMMENDED. The certificates should be submitted with a letter to the
    plan administrator directing the plan administrator to deposit the shares
    represented by such certificates into the plan account of the
    participant. Alternatively, the certificates can be submitted with a
    safekeeping

                                        10


    authorization form. Investors may submit certificates for
    safekeeping at any time while participating in the plan.

    COMMON STOCK SURRENDERED FOR SAFEKEEPING WILL BE TREATED AS SHARES
    PURCHASED THROUGH THE PLAN.

SALE OF SHARES

32. HOW MAY PARTICIPANTS SELL THEIR PLAN SHARES OR TRANSFER SHARES?

    Participants may sell their plan shares by submitting a written request
    to PNM Resources. The request should indicate the number of shares to be
    sold and must be signed by ALL account owners. Shares acquired through
    and held in the plan, as well as shares surrendered for safekeeping, may
    be sold in this manner. A request to sell shares is irrevocable after it
    is received by PNM Resources. PNM Resources's appointed agent will have
    full discretion in all matters related to the sale, including the time of
    sale, sale price, and the markets or persons through whom the shares are
    sold. Participants cannot specify a price at which to sell their stock.

    Participants may also elect to transfer (whether by gift, private sale,
    or otherwise) ownership of all or a portion of their plan shares to the
    account of another participant or establish an account for a person not
    already a participant by delivering to the administrator a completed
    account action request form to that effect and a stock assignment (stock
    power) acceptable to the administrator along with such other
    documentation as may be required by the administrator. No fraction of a
    share of common stock credited to the transferor's account shall be
    transferred unless the transferor's entire account is transferred. For
    participants' convenience a gift certificate is available to represent a
    transfer by gift.

    Shares held outside the plan may not be sold through the plan.

    See Question 9 for information relating to the sale of only a portion of
    a participant's plan shares when the participant has elected the "Partial
    Dividend Reinvestment" option for his or her shares.

33. WHEN WILL PLAN SHARES BE SOLD?

    Plan shares will generally be sold within five business days following
    receipt of the sale request. However, sale requests received during the
    dividend processing period will be delayed until the dividend processing
    period is completed. See "Plan participation presents investors with the
    following disadvantages--D."

    A check will be issued for the proceeds of the sale minus the broker
    commissions, any related service charges and applicable taxes, and will
    be made payable to the registered account owners only.

TERMINATION OF PLAN PARTICIPATION

34. HOW MAY A PARTICIPANT TERMINATE PARTICIPATION IN THE PLAN?

    Participants may terminate participation in the plan either by selling
    all the shares in their plan account or by having a certificate issued
    for a specific number of whole shares in their plan account and selling
    the balance of shares. See Questions 30, 32 and 33. Certificates cannot
    be issued for fractional shares; fractional shares must be sold when
    terminating participation.

    Plan participants must notify PNM Resources in writing of their intention
    to terminate participation in the plan, have all account owners sign the
    request and indicate whether they wish to receive a stock certificate or
    sell their shares.

    Participants terminating their plan participation will receive a plan
    history statement detailing the account history. THIS STATEMENT SHOULD BE
    RETAINED FOR TAX PURPOSES.

    Cash investments received prior to the request to terminate plan
    participation will be invested during the next investment period unless
    the participant timely requests the return of that cash investment. See
    Question 19.

                                        11


    The termination of plan participation will be delayed if the request is
    received during the dividend processing period. See "Plan participation
    presents investors with the following disadvantages--D."

35. MAY PNM RESOURCES TERMINATE A PARTICIPANT'S PLAN PARTICIPATION?

    Yes. If a participant does not maintain at least one whole share of
    common stock in the plan account or does not own any common stock of
    record for which cash dividends are designated for reinvestment pursuant
    to the plan, the participant's participation may be terminated by PNM
    Resources upon written notice to the participant. A participant whose
    participation has been terminated will receive a check for the cash value
    of any fractional share in the plan account.

    In addition, PNM Resources may terminate a participant's participation in
    the plan if it believes that such participation may be contrary to the
    general intent of the plan or in violation of applicable law. The
    participant will receive a certificate for whole shares and a check for
    the cash value of the fractional share in the plan account.

COSTS

36. WHAT COSTS ARE ASSOCIATED WITH PARTICIPATION IN THE PLAN?

    The only costs associated with plan participation are the broker
    commissions, related service charges and applicable taxes for the sale or
    purchase of shares for a participant's account. All other administrative
    costs are borne by PNM Resources.

REPORTS TO PARTICIPANTS

37. WHAT REPORTS ARE SENT TO PARTICIPANTS?

    Plan participants will receive an investment statement as soon as
    possible after each month in which an investment occurs in their plan
    account, which will provide detailed account information for the current
    calendar year. THIS STATEMENT SHOULD BE RETAINED FOR TAX PURPOSES.

    Participants who have sold, transferred, or withdrawn shares from their
    plan accounts will receive a plan history statement detailing the account
    history. THIS STATEMENT SHOULD BE RETAINED FOR TAX PURPOSES.

    Plan participants will also receive copies of all shareholder
    communications such as annual reports, and notices of shareholder
    meetings and proxy materials.

    Plan participants will receive an IRS Form 1099-DIV showing total
    dividends reported to the Internal Revenue Service which were paid to the
    participant both on shares of record and plan account shares. An IRS
    Form 1099-B will be provided for reporting the proceeds from the sale of
    shares through the plan. See Question 45 for further information
    regarding tax reporting.

OTHER INFORMATION

38. WHAT HAPPENS IF PNM RESOURCES DECLARES A DIVIDEND PAYABLE IN COMMON
    STOCK OR A STOCK SPLIT?

    Any dividends in the form of shares of common stock and any shares
    resulting from a common stock split on shares held in a participant's
    plan account will be credited to the participant's plan account.

39. HOW WILL A PARTICIPANT'S SHARES BE VOTED AT MEETINGS OF SHAREHOLDERS?

    Participants in the plan will receive a proxy statement and a proxy card
    representing plan account shares as well as any other common stock held
    of record. The participant's shares will be voted in accordance with the
    instructions indicated on the proxy card. Shares for which a proxy is not
    received will not be voted.

                                        12


40. WHAT IS THE RESPONSIBILITY OF PNM RESOURCES AND ITS AGENTS UNDER THE
    PLAN?

    Neither PNM Resources, in its individual capacity or as administrator,
    nor any independent agent appointed by PNM Resources pursuant to the plan
    will be liable for any act done in good faith or for any good faith
    omission to act with respect to the plan, including, without limitation,
    any claim of liability arising out of failure to terminate a
    participant's account upon such participant's death prior to receipt of
    notice in writing of such death or with respect to the prices or times at
    which, or sources from which, shares are purchased or sold for
    participants, or with respect to any fluctuation in market value before
    or after any purchase or sale of shares.

    PARTICIPANTS MUST RECOGNIZE THAT PNM RESOURCES CANNOT ASSURE THEM A
    PROFIT, OR PROTECT THEM AGAINST LOSSES, ON SHARES PURCHASED PURSUANT TO
    THE PLAN. THE MARKET PRICE OF COMMON STOCK CAN FLUCTUATE SUBSTANTIALLY.
    PARTICIPANTS ACCEPT THE RISKS AS WELL AS THE BENEFITS OF THE PLAN.

41. MAY THE PLAN BE CHANGED OR DISCONTINUED?

    Yes. PNM Resources reserves the right to suspend, modify, or terminate
    the plan at any time. PNM Resources may register additional shares from
    time to time. Any suspension, modification, or termination of the plan
    will be communicated by PNM Resources to all plan participants.

42. MAY COMMON STOCK HELD IN A PLAN ACCOUNT BE PLEDGED AS COLLATERAL?

    No. Common stock held in a plan account may not be pledged as collateral.
    Participants wishing to use their common stock as collateral must have
    certificates issued for the shares. The certificates can then be
    delivered for collateral.

43. MAY COMMON STOCK HELD IN A PLAN ACCOUNT BE TRANSFERRED OR ASSIGNED TO
    ANOTHER PERSON?

    Yes. A participant may transfer or assign plan shares to another person
    or entity by meeting the requirements for transfer of stock. Requests for
    stock transfer requirements should be sent to:

       PNM Resources, Inc.
       Shareholder Records Department
       Alvarado Square, MS 1104
       Albuquerque, NM 85158-1104

    or by calling PNM Resources at (800) 545-4425 or, in Albuquerque, at
    241-2054.

    See Question 9 for information relating to the transfer of only a portion
    of a participant's plan shares when the participant has elected the
    "Partial Dividend Reinvestment" option for his or her shares.

44. HOW MAY INSTRUCTIONS BE GIVEN TO THE ADMINISTRATOR?

    Although currently all instructions from a participant to the
    administrator are required to be in writing, the administrator may in the
    future allow certain instructions to be given by telephone or in any
    other manner as agreed to by the administrator and the participant.

FEDERAL INCOME TAX INFORMATION

45. WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES OF PLAN PARTICIPATION?

    PNM Resources believes the following is an accurate summary of the
    material federal income tax consequences of participation in the plan.
    YOU ARE ADVISED TO CONSULT YOUR TAX OR FINANCIAL ADVISOR WITH RESPECT TO
    FEDERAL, STATE, LOCAL, AND OTHER TAX LAWS WHICH APPLY TO YOUR SPECIFIC
    SITUATION.

                                        13


    In general, the dividends paid on common stock, whether the shares are
    held in certificate form by the shareholder or held through the plan, are
    considered taxable income, whether received in cash or reinvested through
    the plan. The information return sent to you and the IRS at year-end will
    provide the information required to complete your income tax returns.

    The tax basis of shares acquired through the reinvestment of dividends
    will be equal to the value of dividends reinvested. The tax basis of
    shares purchased with cash investments will be equal to the amount of
    such investments.

    Upon the sale of all or a portion of the shares from the plan, a
    participant may recognize a capital gain or loss based on the difference
    between the sales proceeds and the tax basis in the shares sold,
    including any fractional shares. The capital gain or loss will be
    long-term if the shares were held for more than one year.

    For participants who are subject to U.S. withholding tax, backup
    withholding, or foreign taxes, PNM Resources will withhold the required
    taxes from the gross dividends or proceeds from the sale of shares. The
    dividends or proceeds received by the participant, or dividends
    reinvested on behalf of the participant, will be net of the required
    taxes.

                                USE OF PROCEEDS

    Since purchases of common stock under the plan may be satisfied by (i) the
purchase of new shares of common stock issued by PNM Resources or the purchase
of shares held in the treasury of PNM Resources, or (ii) the purchase of
shares of common stock in the open market, the number of shares of newly
issued common stock or treasury shares of common stock, if any, that PNM
Resources ultimately will sell under the plan is not known. If newly issued
shares of common stock or treasury shares of common stock are purchased under
the plan, the proceeds from such sales will be used for general corporate
purposes, including, without limitation, the redemption, repayment or
retirement of outstanding indebtedness of PNM Resources. PNM Resources will
not receive any proceeds when shares of common stock are purchased under the
plan in the open market.

                          DESCRIPTION OF CAPITAL STOCK

    The authorized capital stock of PNM Resources consists of 10,000,000
shares of preferred stock without par value, issuable in series from time to
time, and 120,000,000 shares of common stock, without par value. The board of
directors of PNM Resources is authorized by PNM Resources's Articles of
Incorporation, at any time or from time to time, to establish and designate
one or more series of preferred stock and to fix the number of shares and the
relative rights, preferences and limitations of each such series. PNM
Resources's Articles of Incorporation limit the board of directors to
designating voting rights only when dividends on the preferred stock are not
paid and when proposed changes to the Articles would adversely affect
preferred shareholders' rights. The affirmative vote of the holders of a
majority of the outstanding capital stock of PNM Resources entitled to vote
shall be required in order to amend, alter, change or repeal any provisions of
the Articles of Incorporation.

       PNM Resources common stock is listed on the New York Stock Exchange
under the ticker symbol PNM.

DIVIDENDS

    After giving effect to any prior rights of the PNM Resources preferred
stock, if any should become outstanding, PNM Resources will pay dividends on
its common stock as determined by its board of directors out of legally
available funds.

VOTING RIGHTS

    Holders of common stock are entitled to one vote for each share held by them
on all matters submitted to the shareholders of PNM Resources. Holders of PNM
Resources common stock do not have cumulative voting rights in the election of
directors. The New Mexico Business Corporation Act and PNM Resources's Articles
of Incorporation and Bylaws generally require the affirmative vote of a majority
of the shares represented at the annual meeting and entitled to vote for
shareholder action, including the election of directors. Under the New Mexico


                                        14


Business Corporation Act and PNM Resources's Articles of Incorporation, some
corporate actions, including amending the Articles and approving a plan of
merger, consolidation or share exchange, require the affirmative vote of a
majority of the outstanding shares entitled to vote.

LIQUIDATION

    In the event PNM Resources is liquidated or dissolved, either voluntarily
or involuntarily, the holders of any PNM Resources preferred stock established
by its board of directors would have priority (after any creditors of PNM
Resources) with respect to the distribution of assets. After the holders of
any such preferred stock are paid their aggregate liquidation preference, the
holders of common stock would be entitled, to the exclusion of the holders of
preferred stock, to share ratably (according to the number of shares held by
them) in all remaining assets of PNM Resources available for distribution.

PREEMPTIVE AND OTHER RIGHTS

    Holders of PNM Resources's capital stock do not automatically have any
preemptive rights to purchase shares of PNM Resources's common or preferred
stock (or their equivalents). PNM Resources common stock is not subject to
redemption or to any further calls or assessments and is not entitled to the
benefit of any sinking fund provisions. The shares of PNM Resources common
stock to be issued to PNM common shareholders in connection with the share
exchange will be fully paid and non-assessable once the share exchange is
completed.
