Agreement is extended, at any time prior to the end of the then current term.

Event of Default described in Sections 10.1(f) and 10.1(g) hereof, even if Agent and Lenders do not exercise the right to terminate this Agreement, but elect, at their option, to provide financing to any Borrower or permit the use of cash collateral
under the United States Bankruptcy Code. The early termination fee provided for in this Section 13.1 shall be deemed included in the Obligations.”
