                  that any Event of Default exists hereunder or if any condition
                  exists which,  with the giving of notice,  the passing of time
                  or both would cause an Event of Default. Borrower shall submit

                  writing, and such request shall include a detailed description
                  of the use of proceeds and Borrower's  certification  that the
                  conditions to funding are  satisfied.  Borrower  shall further
                  provide Lender such information and documents as Lender or its
                  counsel  may  reasonably   require  in  the  course  of  usual

Agreement executed by Borrower and Lender dated as of May 7, 1997, the Trademark

debts and obligations secured thereby.

         10.  Borrower  represents  and  agrees  that  all  representations  and
warranties made in the Loan Agreement are true as of the date hereof,  excepting
