Any such notations on such SCHEDULE (and on any such continuation) indicating the outstanding principal amount of the Holder's Revolving Loans shall be rebuttable presumptive evidence of the principal amount thereof owing and unpaid, but the failure to record any such amount on such SCHEDULE (or on such continuation), or any error in recording any such amount on such SCHEDULE (or on such continuation), shall not limit or otherwise affect the Obligations of the Borrower hereunder or under the Credit Agreement to make repayments or prepayments of principal of, or payments of interest on, this Revolving Credit Note when due. The Borrower agrees to pay interest on the principal amount of this Revolving Credit Note from time to time unpaid, all in accordance with ARTICLE II of the Credit Agreement.

(Boston, Massachusetts time), on the due date, and funds received after that hour shall be deemed to have been received by the Administrative Agent on the next following Business Day, and any applicable interest or Fees shall continue to accrue until such payment shall be deemed to have been received. All computations of commitment fees, and of interest payable in respect of Base Rate Loans based upon the Base Rate, shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest under the Credit Agreement shall be made on the basis of a 360-day year and actual days elapsed.
