     with Section 3.1(d), Borrower shall provide the Lender a 
     calculation of the foregoing Borrowing Base on the Borrowing Base 
     Report. In the event, at any time, the aggregate unpaid principal

     Base calculated as described above, the Borrower will promptly, but

time permit:

     quarters ending February 28 and November 30, excluding from Debt of 
     the Borrower for the purposes of this calculation any payable 
     incurred to acquire inventory which is due by its terms more than 
     60 days after February 28 and November 30;

          (b)  its Minimum Debt Coverage Ratio to be less than 1.25

the period for which the applicable report is delivered.

inventory owned by Ener-Tech Industries, Inc., a Tennessee 
corporation, shall not constitute Eligible Inventory or Eligible 
Other Inventory until such time as Lender has determined, in its 
sole and absolute discretion, that Lender holds a first and prior 
security interest in such accounts and inventory.

$8,000,000.00                                               February 20, 1996

     FOR VALUE RECEIVED, after date, without grace, in the manner, 
on the dates and in the amounts so herein stipulated, the 
undersigned, ACR GROUP, INC., acting by and through its duly 
authorized officer, ("Borrower"), PROMISES TO PAY TO THE ORDER OF 
NATIONSBANK OF TEXAS, N.A. ("Lender"), in Houston, Harris County, 
Texas, the sum of EIGHT MILLION AND NO/100 DOLLARS ($8,000,000.00) 
or, if less, the aggregate unpaid principal amount of advances made 
by Lender to Borrower pursuant to this Note, in lawful money of the 
United States of America, which shall be legal tender in payment of 
all debts and dues, public and private, at the time of payment, and 
to pay interest on the unpaid principal amount from date until 
maturity at a rate equal to the Stated Rate (hereinafter defined), 
not to exceed the maximum non-usurious interest rate permitted by 
applicable law from time to time in effect as such law may be 
interpreted, amended, revised, supplemented or enacted ("Maximum 
Rate"), provided that if any any time the Stated Rate exceeds the 
Maximum Rate then interest hereon shall accrue at the Maximum Rate. In the 
event the Stated Rate subsequently decreases to a level which would be less 
than the Maximum Rate or if the Maximum Rate applicable to this Note should 
subsequently be changed, then interest hereon shall accrue at a rate equal to 
the applicable Maximum Rate until the aggregate amount of interest so accrued 
equals the aggregate amount of interest which would have accrued at 
the Stated Rate without regard to any usury limit, at which time 
interest hereon shall again accrue at the Stated Rate. This Note is 
payable as follows:

          Interest shall be due and payable monthly as it accrues, 
     on the last day of each and every month, beginning February 29, 
     1996, and continuing regularly thereafter until February 28, 1998, 
     when the entire balance of principal and accrued interest shall be 
     due and payable.

     It is agreed that time is of the essence of this agreement. In 
the event of default in the payment of any installment of principal 
or interest when due or in the event of any other default 
hereunder, Lender may accelerate and declare this Note immediately 
due and payable without notice. Any failure to exercise this option 
shall not constitute a waiver by Lender of the right to exercise 
the same at any other time.

     In the event of default in the making of any payment herein 
provided, either of principal or interest, or in the event this 
Note is declared due, interest shall accrue at the Maximum Rate.



     As used herein, the Stated Rate shall mean:

    Applicable Minimum
 Net Income Before Taxes                            Stated Rate
- ---------------------------                         -----------

Borrower's consolidated net income                  Prime Rate + 1.00%
before taxes for the preceding four
fiscal quarters is less than $750,000

Borrower's consolidated net income                  Prime Rate + .50%
before taxes for the preceding four
fiscal quarters is equal to or greater
than $750,000.

     As used in this Note, the term "Prime Rate" shall mean the 
variable rate of interest announced by Lender from time to time as 
its prime rate of interest and, without notice to the maker of this 
Note or any other person, such rate of interest shall change as and 
when changes in that prime rate of interest are announced. The 
Prime Rate is set by Lender as a general reference rate of 
interest, taking into account such factors as Lender may deem 
appropriate, it being understood that many of Lender's commercial or 
other loans are priced in relation to such rate, that it is not 
necessarily the lowest or best rate of interest actually charged on 
any loan, and that Lender may make various commercial or other 
loans at rates of interest having no relationship to the Prime 
Rate. If at any time the "Prime Rate" of Lender is not longer 
available, then the owner of this Note ("Owner") will designate a 
difference "Prime Rate" as announced by a national banking 
association of Owner's choice.

     Borrower hereby agrees to pay all expenses incurred, including 
reasonable attorney's fees, all of which shall become a part of the 
principal hereof, if this Note is placed in the hands of an 
attorney for collection or if collected by suit or through any probate,
bankruptcy or any other legal proceedings.

     Interest charges will be calculated on amounts advanced 
hereunder on the actual number of days these amounts are 
outstanding on the basis of a 360-day year, except for calculations 
of the Maximum Rate which will be on the basis of a 365-day or 
366-day year, as is applicable. It is the intention of the parties 
hereto to comply with all applicable usury laws; accordingly, it 
is agreed that notwithstanding any provision to the contrary in 
this Note, or in any of the documents securing payment hereof or 
otherwise relating hereto, no such provision shall require the payment or
permit the collection of interest in excess of the Maximum Rate. 
If any excess of interest in such respect is provided for, or shall 
be adjudicated to be so provided for, in this Note or in any of the 
documents securing payment hereof or otherwise relating hereto, then in
such event (1) the provisions of this paragraph shall govern and control, 
(2) neither Borrower, endorsers or guarantors, 


- ------------
Initials


nor their heirs, legal representatives, successors or assigns nor any other 
party liable for the payment hereof, shall be obligated to pay the amount of 
such interest to the extent that it is in excess of the Maximum Rate, (3) 
any such excess which may have been collected shall be either applied as a 
credit against the then unpaid principal amount hereof or refunded to 
Borrower, and (4) the provisions of this Note and any documents securing 
payment of this Note shall be automatically reformed so that the effective 
rate of interest shall be reduced to the Maximum Rate. For the purpose of 
determining the Maximum Rate, all interest payments with respect to this 
Note shall be amortized, prorated and spread throughout the full term of 
the Note so that the effective rate of interest on account of this Note is 
uniform throughout the term hereof.

    Borrower agrees that the Maximum Rate to be charged or collected 
pursuant to this Note shall be the applicable indicated rate ceiling as 
defined in TEX. REV. CIV. STAT. ANN. Art. 5069-1.04, provided that Lender 
may rely on other applicable laws, including without limitation laws of 
the United States, for calculation of the Maximum Rate if the application 
thereof results in a greater Maximum Rate. Except as provided above, the 
provisions of this Note shall be governed by the laws of the State of Texas.

    Each maker, surety, guarantor and endorser (i) waives demand, grace, 
notice, presentment for payment, notice of intention to accelerate the 
maturity hereof, notice of acceleration of the maturity hereof and protest, 
(ii) agrees that this Note and the liens securing its payment may be 
renewed, and the time of payment extended from time to time, without 
notice and without releasing any of the foregoing, and (iii) agrees that 
without notice or consent from any maker, surety, guarantor, or endorser, 
Lender may release any collateral which may from time to time be pledged to 
secure repayment of this Note, or may release any party who might be liable 
for this Note. Borrower grants to Lender a lien on any of Borrower's funds 
which may from time to time be deposited with Lender.

     Borrower may prepay this Note, in whole or in part, at any time prior
