The Lender consents to the Borrower entering into any agreement or agreements to incur Debt or sell securities, including equity, debt, or convertible or other securities, and any refinancings or future amendments or modifications thereof, the proceeds of which are used to finance all or a portion of the repurchase of the Borrower’s Common Stock under the Program, all on such terms, including amount, rate, maturity, security, guarantees, conversion features, covenants and otherwise, as Borrower shall in its full discretion deem necessary or appropriate; provided that such Debt is initially incurred or such securities are initially sold on or before July 31, 2006.

The Lender hereby waives application of Section 2.02(e) of the Loan Agreement to the borrowing contemplated herein.
