               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.       INCORPORATION OF DOCUMENTS BY REFERENCE.

              At the annual meeting of the shareholders of Public Service
Company of New Mexico ("PNM") held on June 6, 2000, shareholders of PNM approved
management's plan to create a new holding company pursuant to the Agreement and
Plan of Share Exchange (the "Plan of Exchange"), dated as of April 17, 2000, by
and between PNM and PNM Resources, Inc., a New Mexico corporation formerly known
as Manzano Corporation ("PNM Resources"). Effective December 31, 2001, pursuant
to the Plan of Exchange, the outstanding shares of common stock ($5.00 par
value) of PNM were automatically exchanged on a share-for-share basis for common
stock (without par value) of PNM Resources. This transaction resulted in PNM
becoming a wholly owned subsidiary of PNM Resources.

PNM and PNM Resources, are hereby incorporated by reference in this registration
statement:

ITEM 4.       DESCRIPTION OF SECURITIES.

              Not applicable.

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's 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.

              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 of 1933;

                            (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;

                            (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 Securities
Exchange Act of 1934 that are incorporated by reference in the registration
statement.

              2.     That, for the purpose of determining any liability under
the Securities Act of 1933, 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 of 1933, each filing of the registrant's annual report pursuant
to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) 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 of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by 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 Act and will be governed by the final adjudication of
such issue.
