                For value received, AQUAGENIX, INC., a Delaware

           time to time hereafter modified and amended is referred to herein as 
           the "Credit Agreement"), between the Borrower and the Lender.  Each 
           holder hereof is entitled to the benefits and security provided 
           thereby or referred to therein, to which Credit Agreement reference 
           is hereby made for a statement thereof.  Reference is made to such 
           Credit Agreement for rights as to prepayment hereof and the 
           acceleration of the maturity hereof.          
          
          The Borrower hereby agrees to pay all costs incurred by any holder
     hereof, including reasonable attorney's fees (Including those for appellate
     proceedings), incurred in connection with any Event of Default (as defined
     in the  Credit Agreement), or in connection with the collection or    
     attempted collection or enforcement hereof, or in connection with the      
     protection of  any collateral given as security for the payment hereof,  
     whether or not legal proceedings may have been instituted.       
      
          All parties to this Note, including the Borrower and any sureties,    
     endorsers or guarantors, hereby waive presentment for payment, demand, 
     protest, notice of dishonor, notice of acceleration of maturity, and all  
     defenses on the ground of extension of time for payment hereof, and agree 
     to continue and remain bound for the payment of principal, interest, and 
     all other sums payable hereunder, notwithstanding any change or changes by 
     way of release, surrender, exchange or substitution of any security for 
     this Note or by way of any extension or extensions of time for payment of 
     principal or interest; and all such parties waive all and every kind of 
     notice of such change or changes and agree that the same may be made 
     without notice to or consent of any of them.  The rights and remedies of 
     the holder as provided herein shall be cumulative and concurrent and may 
     be pursued singularly, successively or together at the sole discretion of 
     the holder, and may be exercised as often as occasion therefor shall occur,
     and the failure to exercise any such right or remedy shall in no event be 
     construed as a waive or release of the same.     
     
     Anything herein to the contrary notwithstanding, the obligations of   
     the borrower under this Note shall be subject to the limitation that       
     payments of interest to the Lender shall not be required to the extent that
     receipt of any such payment by the Lender would be contrary to provisions
     of law applicable to the Lender (if any) which limit the maximum rate of   
     interest which may be charged or collected by the Lender; provided, 
     however, that nothing herein shall be construed to limit the Lender to  
     presently existing maximum rates of interest, if any increased interest 
     rate is hereafter permitted by reason of applicable federal or state 
     legislation. In the event that the Borrower make any payment of interest, 
     fees or other charges, however dominated, pursuant to this Note, which 
     payment causes the interest paid to the Lender to exceed the maximum rate 
     of interest permitted by applicable law, any excess over such maximum shall
     be applied in reduction of the principal balance owed to the Lender as of 
     the  date of such payment, or if such excess exceeds the amount of 
     principal owed to the Lender as of the date of such payment, the difference
     shall be paid by the Lender to the Borrower.

               THE Borrower HEREBY, AND THE Lender BY ITS ACCEPTANCE OF THIS 
               NOTE, KNOWINGLY, VOLUNTARILY   AND  INTENTIONALLY WAIVE THE RIGHT
