Such a request shall be in writing (and shall be irrevocable) and shall be delivered to Agent with such other documentation as the Agent may request. Each Bank, the Agent and the Issuing Bank each in its sole discretion may, but shall not be required to, grant such a one-year extension to the Facility Period. The Agent will notify the Borrower in writing fifteen mouths before the end of the Facility Period as to whether the one-year extension will be granted and to advise the Borrower of the new Termination Date and any other conditions to such extension, provided that in the absence of such a notice by the Agent, the extension request will be deemed denied." 4.

The Utilization Fee shall be paid quarterly in arrears on the last day of each calendar quarter and on the Repayment Date." 5. The definition of "Termination Date" in Article 10, Section 10.01 is restated in its entirety as follows: "Termination Date" means: (a) the fourth anniversary of the Agreement Date; or (b) if the Facility Period has been extended pursuant to Section 1.01 (c) either the fifth or sixth anniversary of the Agreement Date, as contained in a notice from the Agent to the Borrower." 6. The definition of "Utilization Fee" in Article 1O, Section 10.01 is amended and restated in its entirety as follows: "Utilization Fee" means the fee of .125% per annum of the aggregate daily amount of the Loans, Letter of Credit Amounts and Unreimbursed Letter of Credit Obligations as described in Section 1.08 (e)." 7.
