ITEM 5.       INTERESTS OF NAMED EXPERTS AND COUNSEL.

              Not applicable.



ITEM 6.       INDEMNIFICATION OF DIRECTORS AND OFFICERS.

              Section 6 of Article II of PNM Resources' By-Laws contains the
following provisions with respect to indemnification of directors and officers:

         Each person serving as a director or an officer of the Corporation, or,
         at the request of the Corporation, as a director or an officer of any
         other company in which the Corporation has a financial interest and
         regardless of whether or not the person is then in office, and the
         heirs, executors, administrators and personal representatives of the
         person, shall be indemnified by the Corporation to the full extent of
         the authority of the Corporation to so indemnify as authorized by New
         Mexico law.

              Section 53-11-4.1 of the Business Corporation Act of the State of
New Mexico provides that a corporation shall have power to indemnify any person
made (or threatened to be made) a party to any proceeding (whether threatened,
pending or completed) by reason of the fact that the person is or was a director
(or, while a director, is or was serving in any of certain other capacities) if:
(1) the person acted in good faith; (2) the person reasonably believed: (a) in
the case of conduct in the person's official capacity with the corporation, that
the person's conduct was in its best interests; and (b) in all other cases, that
the person's conduct was at least not opposed to its best interests; and (3) in
the case of any criminal proceeding, the person had no reasonable cause to
believe the person's conduct was unlawful. Indemnification may be made against
judgments, penalties, fines, settlements and reasonable expenses actually
incurred by the person in connection with the proceeding, but may be limited or
unavailable with respect to certain proceedings. In some instances,
indemnification of a director may be mandatory or, upon the application of a
director, may be ordered by a court. Reasonable expenses incurred by a director
may, under certain circumstances, be paid or reimbursed in advance of a final
disposition of a proceeding. Unless limited by its articles of incorporation, a
corporation may (or, as the case may be, shall) indemnify and advance expenses
to an officer of the corporation to the same extent as to a director under
Section 53-11-4.1. Also, unless limited by its articles of incorporation, a
corporation has (1) the power to indemnify and to advance expenses to an
employee or agent of the corporation to the same extent that it may indemnify
and advance expenses to directors under the statute and (2) additional power to
indemnify and to advance reasonable expenses to an officer, employee or agent
who is not a director to such further extent, consistent with law, as may be
provided by its articles of incorporation, bylaws, general or specific action of
its Board of Directors, or contract.

              Section 53-11-4.1 was amended in 1987 to provide that the
indemnification authorized thereunder shall not be deemed exclusive of any
rights to which those seeking indemnification may be entitled under the articles
of incorporation, the by-laws, an agreement, a resolution of shareholders or
directors or otherwise. PNM Resources has entered into agreements with each
director and officer which provide for indemnification of directors and officers
to the fullest extent permitted by law including advancement of litigation
expenses where appropriate. The agreements provide for the appointment of a
reviewing party by the Board of Directors to make a determination whether
claimed indemnification is permitted under applicable law.

              Insurance is maintained on a regular basis (and not specifically
in connection with this offering) against liabilities arising on the part of
directors and officers out of their performance in such capacities or arising on
the part of PNM Resources out of its foregoing indemnification provisions,
subject to certain exclusions and to the policy limits.

ITEM 7.       EXEMPTION FROM REGISTRATION CLAIMED.

              Not applicable.

ITEM 8.       EXHIBITS.

              See Exhibit Index.

ITEM 9.       UNDERTAKINGS.

              The undersigned registrant hereby undertakes:



              1. To file, during any period in which offers of sales are being
made, a post-effective amendment to this registration statement:

                        (i) To include any prospectus required by Section
              10(a)(3) of the Securities Act;

                       (ii) To reflect in the prospectus any facts or events
              arising after the effective date of the registration statement (or
              the most recent post-effective amendment thereof) which,
              individually or in the aggregate, represent a fundamental change
              in the information set forth in the registration statement.
              Notwithstanding the foregoing, any increase or decrease in volume
              of securities offered (if the total dollar value of securities
              offered would not exceed that which was registered) and any
              deviation from the low or high end of the estimated maximum
              offering range may be reflected in the form of prospectus filed
              with the Commission pursuant to Rule 424(b) if, in the aggregate,
              the changes in volume and price represent no more than a 20
              percent change in the maximum aggregate offering price set forth
              in the "Calculation of Registration Fee" table in the effective
              registration statement; and

                      (iii) To include any material information with respect to
              the plan of distribution not previously disclosed in the
              registration statement or any material change to such information
              in the registration statement;

              PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not apply
if the registration statement is on Form S-3, Form S-8 or Form F-3, and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to Section 13 or 15(d) of the Exchange Act
that are incorporated by reference in the registration statement.

              2. That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

              3. To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

              4. That, for purposes of determining any liability under the
Securities Act, each filing of the registrant's annual report pursuant to
Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of the
Exchange Act) that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

              Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the provisions described under Item 6 above, or
otherwise, the registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
