"BANK"                        "BORROWER"
 
     FOR VALUE RECEIVED, Borrower promises to pay to the order of Bank, its
successors and assigns at Albuquerque, New Mexico (or such other place as the
Bank may designate) (i) the principal amount of Two Million and No/100 Dollars
($2,000,000.00), or so much thereof as is advanced; (ii) the fees and other
charges as provided herein; and (iii) per annum interest on the outstanding
principal balance from Date of Disbursement, until paid at the rate of 0.500%
above the index rate for this loan which is Chase Manhattan Bank Prime, in
effect from time to time, and which is published by Chase Manhattan Bank, N.A.,
with a minimum rate of N/A%.  As of the date of this note, the index rate is
8.500%.  Adjustments in the interest rate will be effective as announced and may
increase or decrease the amount of the regular payments.  If the index rate is
discontinued then the interest rate shall be the rate being charged by Bank on
similar loans.

Borrower agrees to pay as follows:

[X]  Interest on the 28th day of every single month beginning February 28,
1995, and continuing until this Note is paid in full.

     This Loan is payable in full on March 31, 1996.  Borrower must repay the
outstanding principal balance of the loan and unpaid interest then due.  The
Bank is under no obligation to refinance the loan at that time.

     Borrower shall pay Bank a late charge of N/A% or N/A, whichever is less, of
any installment not received by Bank within fifteen (15) days after the
installment is due.

     All payments shall be applied first to reduce fees and charges other than
interest, then to reduce interest, then to reduce principal.

[X]  This is a multiple advance note.  Borrower has received $0.00 and future
principal advances are contemplated.  No principal advances will be made after
March 31, 1996.  Repaying a part of the principal will entitle Borrower to
additional advances unless an event of default has occurred, or the open-end
feature has expired.

                                       16

 
     Each of the following are events of default under this Note: (i) Failure to
make a payment on time or in the amount due; (ii) Default under any agreement
made in connection with or securing this Note; (iii) Borrower's default on any
other agreement with Bank; (iv) Borrower's death, incompetency, bankruptcy or
insolvency; (v) any written statement or financial information provided by
Borrower is untrue or inaccurate; or (vi) any other event which reasonably
causes Bank to be insecure about being repaid or about the adequacy of the
security for this Note.

     Upon the occurrence of any event of default contained in this Note, the
Bank may declare the principal amount, accrued interest thereon, and fees and
other charges as provided in this Note immediately due and payable without
notice or demand, refuse to make any further advances under this Note, enforce
its rights under any document securing the indebtedness evidenced by this Note,

indebtedness evidenced by this Note, and use any remedy available under state or
federal law.

     No delay or omission on the part of Bank in exercising any right hereunder

SUNWEST BANK                             New Mexico Utilities, Inc.
of Albuquerque, N.A.                     A New Mexico Corporation

(505) 765-2211
"BANK"                        "BORROWER"
 
     FOR VALUE RECEIVED, Borrower promises to pay to the order of Bank, its
successors and assigns at Albuquerque, New Mexico (or such other place as the
Bank may designate) (i) the principal amount of Five Hundred Thousand and No/100
Dollars ($500,000.00), or so much thereof as is advanced; (ii) the fees and
other charges as provided herein; and (iii) per annum interest on the
outstanding principal balance from Date of Disbursement, until paid at the rate
of 0.500% above the index rate for this loan which is Chase Manhattan Bank
Prime, in effect from time to time, and which is published by Chase Manhattan
Bank, N.A., with a minimum rate of N/A%.  As of the date of this note, the index
rate is 8.500%.  Adjustments in the interest rate will be effective as announced
and may increase or decrease the amount of the regular payments.  If the index
rate is discontinued then the interest rate shall be the rate being charged by
Bank on similar loans.

Borrower agrees to pay as follows:

[X]  Interest on the 28th day of every single month beginning February 28,
1995, and continuing until this Note is paid in full.

     This Loan is payable in full on March 31, 1996.  Borrower must repay the
outstanding principal balance of the loan and unpaid interest then due.  The
Bank is under no obligation to refinance the loan at that time.

     Borrower shall pay Bank a late charge of N/A% or N/A, whichever is less, of
any installment not received by Bank within fifteen (15) days after the
installment is due.

     All payments shall be applied first to reduce fees and charges other than
interest, then to reduce interest, then to reduce principal.

[X]  This is a multiple advance note.  Borrower has received $0.00 and future
principal advances are contemplated.  No principal advances will be made after
March 31, 1996.  Repaying a part of the principal will entitle Borrower to
additional advances unless an event of default has occurred, or the open-end
feature has expired.

                                       19

 
     Each of the following are events of default under this Note: (i) Failure to
make a payment on time or in the amount due; (ii) Default under any agreement
made in connection with or securing this Note; (iii) Borrower's default on any
other agreement with Bank; (iv) Borrower's death, incompetency, bankruptcy or
insolvency; (v) any written statement or financial information provided by
Borrower is untrue or inaccurate; or (vi) any other event which reasonably
causes Bank to be insecure about being repaid or about the adequacy of the
security for this Note.

     Upon the occurrence of any event of default contained in this Note, the
Bank may declare the principal amount, accrued interest thereon, and fees and
other charges as provided in this Note immediately due and payable without
notice or demand, refuse to make any further advances under this Note, enforce
its rights under any document securing the indebtedness evidenced by this Note,
set off the amount Borrower owes Bank against any funds on deposit with Bank,
retain the proceeds of any checks, drafts, notes or other instruments or
acceptances which it may hold or have in the process of collection for the
account of any of the makers, endorsers and guarantors hereof and may apply such
proceeds (together with any funds on deposit with Bank) to the payment of the
indebtedness evidenced by this Note, and use any remedy available under state or
federal law.

     No delay or omission on the part of Bank in exercising any right hereunder
shall operate as a waiver of such right or of any other right under this Note.
A waiver on any occasion shall not be construed as a bar to, or waiver of, any
such right or remedy on any future occasion.

     Every maker, endorser and guarantor of this Note, or the indebtedness
represented hereby waives presentment, demand, notice, protest, and all other
demands and notices in connection with the delivery, acceptance, performance,
default or enforcement of this note and assents to any extension or postponement
of the time of payment or other indulgence, to the addition or release of any
other party or person primarily or secondarily liable on this note or to the
addition or release of any security interest or collateral securing this note.

     Any time this Note is placed in the hands of an attorney for collection, or
to defend or enforce any of the Bank's rights hereunder, Borrower shall pay to
the Bank its reasonable attorneys' fees, together with all court costs and other
expenses.

     If no default exists hereunder, Borrower may prepay at any time, without
premium or fee, the entire indebtedness or any part thereof evidenced by this
Note and such prepayments shall be applied in the manner scheduled payments are
applied unless Borrower directs Bank to apply such prepayment in reduction of
the outstanding principal indebtedness.  Partial prepayments shall not postpone
the due date of any subsequent monthly installments or change the amount of such
installments (other than the amount of interest) and shall not postpone the due
date for payment of the indebtedness evidenced by this Note.

     Borrower has delivered and shall deliver to Bank within 120 days after the
end of each annual accounting period of Borrower and at such other times as Bank
may request, copies of its balance sheet, income statement, cash flow analysis,
list of contingent liabilities and such other financial

                                       20

and represents to Bank that the financial information delivered, and to be
