2. Amendment to Section 2(a) of the Agreement. Section 2(a) of the Agreement is hereby deleted in its entirety and replaced with the following:

(a) Establishment of Credit Facility.

Notwithstanding anything contained herein to the contrary, an Overadvance shall be considered a Loan and shall bear interest at the Rate as set forth in the Revolving Credit Note and be secured by this Agreement. Subject to the terms and conditions hereof, Debtor may borrow, repay and reborrow funds under the Revolving Credit Facility up to the Revolving Credit Maturity Date.
