For purposes hereof, "Prime Rate" shall mean the rate of interest per annum announced from time to time by the Lender as its prime rate in effect at its principal office in Cleveland, Ohio; each change in the Prime Rate shall be effective on the date such change is announced. The Prime Rate may not be publicly announced or published and does not necessarily represent the lowest or best rate at which Lender will extend credit. 1. OTHER LOAN DOCUMENT AMENDMENTS. Each of the other Loan Documents are amended to reflect and to incorporate the amendment to the Credit Agreement as set forth above. 1. DOCUMENT RATIFICATION.
