exercise of legal right and power in them vested, execute this 1994
Supplemental Indenture:

          NOW, THEREFORE, THIS 1994 SUPPLEMENTAL INDENTURE
WITNESSETH:

                           ARTICLE ONE

                 AMENDMENT TO ORIGINAL INDENTURE
                         WITHOUT CONSENT

          SECTION 1.01.  Amendment to Original Indenture.

          The first and second paragraphs of Section 7.01 of the
Original Indenture are designated paragraphs "(a)" and "(b)",
respectively.  There is added to the Original Indenture the
following provision:

          "(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 upon reasonable notice."

          SECTION 1.02.  Effectiveness.

          (a) The amendments to the Original Indenture specified in
Section 1.01 shall become effective for all purposes of the
Indenture, without necessity for further act by or notice to PNM,
the Company or the Trustee, upon the execution and delivery of this
1994 Supplemental Indenture by the Trustee.

          (b) Upon the effectiveness of the amendments to the
Original Indenture specified in Section 1.01, the Original
Indenture shall, as provided in Section 11.05 thereof, be modified
accordingly and such amendments shall form a part of the Indenture
for all purposes and every Holder of 1986A Bonds shall be bound
thereby.

                           ARTICLE TWO

                          MISCELLANEOUS

          SECTION 2.01.  Execution as Supplemental Indenture;

otherwise defined, the use of the terms herein is in accordance
with the definitions contained in the Original Indenture.

          SECTION 2.02.  Responsibility for Recitals, etc.

          The recitals contained herein shall be taken as the
statements of the Company and PNM, and the Trustee assumes no
responsibility for the correctness of the same.  The Trustee makes
no representation as to the validity or sufficiency of this 1994

contract under the laws of the State of New York, and for all
purposes shall be governed by and construed in accordance with the
laws of said state.

          SECTION 2.05.  Counterparts.

          This 1994 Supplemental Indenture may be executed in any
number of counterparts, each of which shall be an original; but
such counterparts shall together constitute but one and the same
instrument.
          IN WITNESS WHEREOF, the Company, PNM and the Trustee have
caused this 1994 Supplemental Indenture to be duly executed by
their respective officers thereunto duly authorized, as of the date
and year first above written.
