"FIRST AMENDMENT": That certain First Amendment to Amended and Restated Credit Agreement dated as of March 15, 1999, by and among the Borrower, the Banks and the Agent." "FIRST AMENDMENT EFFECTIVE DATE": The date on which the First Amendment becomes effective under paragraph 6 of the First Amendment.

"PERCENTAGE": As to any Bank, the percentage set forth opposite such Bank's signature on the signature page of the First Amendment (or in the relevant Assignment and Assumption Agreement for such Bank) (I.E., the proportion, expressed as percentage, that such Bank's Commitment bears to the Aggregate Commitment). "TERMINATION DATE": The earliest of (a) March 17, 2000, or such later date to which the Termination Date is extended pursuant to the provisions of SECTION 2.9, (b) the date on which the Commitments are terminated pursuant to SECTION 10.2 hereof or (c) the date on which the Commitments are reduced to zero pursuant to SECTION 4.3 hereof." 2.

Upon receipt of such Revolving Note marked "Cancelled" from Chase, the Agent shall promptly return such Revolving Note to the Borrower. 3.

The Revolving Notes have been issued in replacement of, and in substitution for, but not in payment of, the First Replacement Revolving Notes which, in turn, had been issued in replacement of, and in substitution for, but not in payment of, the Original Notes. Each Bank shall enter in its respective records the amount of each Revolving Loan, the rate or rates of interest borne by its Revolving Loans and the payments made on the Revolving Loans, and such records shall be deemed conclusive evidence of the subject matter thereof, absent manifest error." 5. REMAINING EXTENSIONS OF THE TERMINATION DATE. The Borrower, the Banks and the Agent acknowledge and agree that extension of the Termination Date effected by this Amendment constitutes the first extension of the Termination Date contemplated by SECTION 2.9 of the Credit Agreement.
