The sum calculated pursuant to clause (iii) above shall be discounted at the annual rate of the applicable Current Yield on such Term Note to be prepaid to the present value thereof as of the applicable Prepayment Date, on the assumption that said sum would be received in equal monthly installments on each monthly anniversary of the applicable Prepayment Date prior to the Maturity Date on such Term Note to be prepaid, with the final such installment to be deemed received on the Maturity 5 Date on such Term Note to be prepaid; provided that Borrowers shall not be entitled in any event to a credit against, or a reduction of, the Debt being prepaid if the applicable Current Yield on such Term Note to be prepaid exceeds the Fixed Rate or for any other reason. (h) The proviso at the conclusion of Paragraph 8.2(g)(iv) is amended and restated to read in its entirety as follows: provided, however, that the amount of Capital Expenditures may exceed the limits set forth above on a cumulative basis so long as the aggregate amount of Capital Expenditures are (a) made with funds other than proceeds of Funded Debt classified as current liabilities under GAAP and (b) at all times not in excess of $7,900,000 plus 75% of Borrower's net income, in accordance with GAAP, for the period from the Closing Date and thereafter.
