          FOR VALUE RECEIVED, PAMECO CORPORATION ("Pameco"), a Georgia
                                                   ------             
corporation formerly known as New Pameco Georgia Corporation and the successor
by merger to Pameco Corporation ("Old Pameco") and Pameco Holdings, Inc., both
                                  ----------                                  
Delaware corporations, hereby promises to pay to PAMECO SECURITIZATION
CORPORATION (the "Lender"), for its account, the principal sum of FIFTY MILLION
                  ------                                                       
DOLLARS ($50,000,000) (or such lesser amount as shall equal the aggregate unpaid
principal amount of the PRC Loans made by the Lender to Pameco under the
Transfer Agreement referred to below), in lawful money of the United States of
America and in immediately available funds immediately on the demand of the
Lender.

          The date, amount and interest rate, of each PRC Loan made by the
Lender to Pameco, and each payment made on account of the principal thereof,
shall be recorded by the Lender on its books and, prior to any transfer of this
Note, endorsed by the Lender on the schedule attached hereto or any continuation
thereof.

          This Note is the Pameco Note referred to in the Receivables Transfer
Agreement (as modified and supplemented and in effect from time to time, the
"Transfer Agreement") dated as of May 1, 1996 by and among Old Pameco and the
-------------------                                                          
Lender and evidences PRC Loans made by the Lender thereunder.  Capitalized terms
used in this Note and not defined herein have the respective meanings assigned
to them in the Transfer Agreement.

          The Transfer Agreement provides for prepayments of PRC Loans upon the
terms and conditions specified therein.

          Notwithstanding any other provisions contained in this Note, if at any
time the rate of interest payable by Pameco under this Note, when combined with
any and all other charges provided for in this Note, in the Purchase Agreement
or in any other document (to the extent such other charges would constitute
interest for the purpose of any applicable law limiting interest that may be
charged on this Note), exceeds the highest rate of interest permissible under
applicable law (the "Maximum Lawful Rate"); then so long as the Maximum Lawful
                     -------------------                                      
Rate would be exceeded the rate of interest under this Note shall be equal to
the Maximum Lawful Rate.  If at any time thereafter the rate of interest payable
under this Note is less than the Maximum Lawful Rate, Pameco shall continue to
pay interest under this Note at the Maximum Lawful Rate until such time as the
total interest paid by Pameco is equal to the total interest that would have
been paid had such applicable law not limited the interest rate payable under
this Note.  In no event shall the total interest received by the Lender under
this Note exceed the amount which the
<PAGE>
 
Lender could lawfully have received had the interest due under this Note been
calculated since the date of this Note at the Maximum Lawful Rate.

          If any payment under this Note falls due on a day which is not a
Business Day, then such due date shall be extended to the next succeeding
Business Day and interest (calculated at the Pameco Interest Rate for each day
during the period then ending) shall be payable on the principal so extended.

          This Note is being issued in replacement of and substitution for that
certain Pameco Note dated May 1, 1996, as amended and restated as of January 24,
1997, by Old Pameco to the order of the Lender in the principal amount of
$50,000,000.  In addition to the indebtedness evidenced by this Note, this Note
shall also evidence any accrued and unpaid interest on such preceding note.

          Pameco expressly waives presentment, demand, diligence, protest and
all notices of any kind whatsoever with respect to this Note.

          This Note is made and delivered in New York, New York and shall be
governed by, and construed in accordance with, the internal laws (without
application of its conflict of laws provisions) of the State of New York.

          IN WITNESS WHEREOF, Pameco has caused this Note to be signed and
delivered by its duly authorized officer as of the date set forth above.
