B.    Borrower has requested that Lender extend the Revolving Credit Facility Maturity Date to December 31, 2012. Lender is willing to agree to such requests, subject to the terms set forth herein.

NOW, THEREFORE, in consideration of the promises herein contained, and each intending to be legally bound hereby, the parties agree as follows:

Capitalized terms not specifically defined herein shall have the same meanings as set forth in the Credit Agreement.

To induce Lender to enter into this Agreement, Borrower hereby represents and warrants unto Lender as follows:

1.Authority. The execution, delivery, and performance hereof are within the powers of Borrower, have been duly authorized, and are not in contravention of law or the terms of the articles of incorporation or bylaws of Borrower, or of any indenture, agreement, or undertaking to which Borrower is a party or by which it is bound. The officer of Borrower executing this Agreement is duly and properly in office and fully authorized to execute the same.

2.Enforceability. This Agreement, when executed and delivered by Borrower, will be the legal, valid, and binding agreement of Borrower, enforceable in accordance with its terms except to the extent that the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, or other similar laws and except as the principles of equity may affect the remedy of specific performance.

3.No Consent. No consent or approval of any trustee, issuer or holder of any indebtedness or obligation of Borrower, and no consent, permission, authorization, order or license of any governmental authorities is necessary in connection with the execution and delivery of this Agreement, or any instrument or agreement required hereunder, or any transaction contemplated hereby.

4.Financial Information Accuracy. Subject to any limitations stated therein, all balance sheets, earnings statements, and other financial data of Borrower that have been furnished to Lender to induce it to enter into this Agreement or otherwise in connection herewith, fairly represent the financial condition of Borrower as of the dates and for the periods for which same are furnished, and all other information, reports and papers, and data furnished to Lender are accurate and correct in all material respects and complete and do not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading in light of the circumstances under which they were made. It is understood that projections and forecasts are subject to uncertainties and

contingencies, many of which are beyond the control of Borrower, and that no assurance can be given that such projections and forecasts will actually be realized, and that actual results may differ from the projected results set forth therein by a material amount.

5.Other Representations and Warranties. The representations and warranties made in the Loan Documents continue to be true and correct in all material respects as if made on the date of this Agreement (other than the representations and warranties which were stated to relate solely to an earlier date, in which case such representations and warranties shall be true and correct in all material respects as of such earlier date).

6.No Default. No default exists as of the date of this Agreement under the Loan Documents and no event which would constitute a default upon the giving of notice or mere passage of time currently exists under the Loan Documents.

7.No Default With Other Lenders. No event of default exists as of the date of this Agreement under any loan or credit agreement between Borrower and any lender other than Lender and no event which would constitute an event of default under such an agreement upon the giving of notice or mere passage of time currently exists.
