                                  WITNESSETH:

        THAT WHEREAS, Bank One and Borrower are parties to a Loan Agreement

        1.  Amend Section 6.2 of the Agreement as follows:

        6.2 Borrower agrees to maintain a ratio of Debt to Tangible Net Worth 
            of not more than 2.5 to 1.0.

        2.  Amend Section 6.4 of the Agreement as follows:

        6.4 Borrower agrees to maintain a Cash Flow Ratio (net income before 
interest, taxes, depreciation, amortization, plus (or minus) the change in the 
allowances for doubtful accounts and inventory from quarter to quarter divided 
by interest and current maturities of long term debt) of not less than 1.0 to 
1.0 as of March 31, 1996 and June 30, 1996; 1.5 to 1.0 as of September 30, 
1996; and 2.0 to 1.0 as of December 31, 1996 and thereafter, said ratio 
calculated on a rolling four quarter basis.

        3.  The Borrower and each of the undersigned guarantors authorize(s) 
any Attorney-at-Law to appear for the Borrower and each of the undersigned 
guarantors in action on the Note, at a time after the same becomes due, as 
herein provided, in any court of record in or of the State of Ohio, or 
elsewhere, to waive the issuing and service of process against the Borrower and 
each of the undersigned guarantors, and to confess judgment in favor of the 
legal holder of the Note against the Borrower and each of the undersigned 
guarantors, for the amount that may be due, with interest at the rate therein 
mentioned and cost of suit, and to waive and release all errors in said 
proceedings and judgment rendered.

        4.  As modified and amended by this Amendment to Loan Agreement, the 
original Agreement is in all respects reinstated, ratified and confirmed by the 
parties hereto and the Agreement and this Amendment to Loan Agreement shall be 
read, taken and construed as one and the same instrument.

        IN WITNESS WHEREOF, the undersigned have caused this Amendment to Loan 
Agreement to be executed on the day and year first above written.
