          WHEREAS, Borrower has informed Lender that an Overline in the amount
of  Five Million Seven Hundred Thirty Thousand Dollars ($5,730,000) exists as a
result of the reappraisal of the Equipment of the Loan Parties;

          WHEREAS, in connection therewith, Borrower has requested that Lender
temporarily permit the Overline to remain outstanding;

          WHEREAS, Lender has agreed to temporarily permit the Overline to
remain outstanding as provided herein;

          NOW, THEREFORE, in consideration of the foregoing premises and other
valuable consideration, the parties hereto agree as follows:

          1.    Amendment.  The Agreement is amended as follows:
                ---------                                       
          (a)   Section 1.3 of the Agreement shall be amended and restated in
its entirety as follows:

          "1.3  Overlines.  If at any time or for any reason the outstanding

     amount of advances made pursuant hereto exceeds any of the dollar or
     percentage limitations contained in the Schedule (any such excess, an
     "Overline"), then Borrower shall, upon Lender's demand, immediately pay to
     Lender, in cash, the full amount of such Overline; provided, that if the
                                                        --------             
     amount of such Overline is less than Five Hundred Thousand Dollars
     ($500,000), Borrower shall pay to Lender, in cash, the full amount of such
     Overline within five (5) Business Days following demand by Lender; provided
                                                                        --------
     further, that the Overline in the amount of Five Million Seven Hundred
     -------                                                               
     Thirty Thousand Dollars ($5,730,000) (the "Temporary Overline") arising as
     a result of the reappraisal of the Equipment of the Loan Parties by Taylor

     outstanding until the

 
     "Temporary Overline Expiration Date" (as defined below), at which time the
     Temporary Overline shall be immediately due and payable. "Temporary

     the date either Congress Financial Corporation (Southwest) and/or Madeline,
     L.L.C. terminate the Commitment Letter dated June 19, 1998 issued by them
     to Borrower. Without limiting Borrower's obligation to repay to Lender on
     demand the amount of any Overline, Borrower agrees to pay Lender interest
     on the outstanding principal amount of any Overline, on demand, at the rate
     set forth on the Schedule."

              -----------------------------------

          4.  Representations and Warranties. Borrower represents and warrants

Documents remain in full force and effect. The Loan Documents, as modified by
this Amendment, embody the entire agreement and understanding between Borrower

          8.  Counterparts; Telecopy Execution. This Amendment may be executed
              -------------------------------- 
in any number of separate counterparts, each of which, when taken together,
shall constitute one and the same agreement, admissible into evidence,
notwithstanding the fact that all parties have not signed the same counterpart.

equally as effective as delivery of a manually executed counterpart of this
Amendment. Any party delivering an executed counterpart of this Amendment by
telefacsimile shall also deliver a manually executed counterpart of this
Amendment, but the failure to deliver a manually executed counterpart shall not
affect the validity, enforceability, and binding effect of this Amendment.

          IN WITNESS WHEREOF, the parties hereto have executed this Amendment
effective as of the day, month, and year first above written.
