          (a) Execution and Delivery. Borrower and each Guarantor shall have executed and delivered this Amendment to Administrative Agent;

          (b) Payment of Fee. Borrower shall have paid to Administrative Agent, for the ratable benefit of the Lenders, a fee in an amount equal to 0.15% of the $100,000,000 increase in the Aggregate Commitment.

          (c) Representations and Warranties. The representations and warranties of the Credit Parties under this Amendment are true and correct in all material respects as of such date, as if then made (except to the extent that such representations and warranties related solely to an earlier date);

          (d) No Default. No Default shall have occurred and be continuing;

          (e) Other Documents. The Administrative Agent shall have received such other instruments and documents incidental and appropriate to the transaction provided for herein as the Administrative Agent or its counsel may reasonably request, and all such documents shall be in form and substance satisfactory to the Administrative Agent.

     7. Representations and Warranties. Each Credit Party hereby represents and warrants that (a) except to the extent that any such representations and warranties expressly relate to an earlier date, all of the representations and warranties contained in the Credit Agreement and in each Loan Document are true and correct as of the date hereof after giving effect to this Amendment, (b) the execution, delivery and performance by such Credit Party of this Amendment have been duly authorized by all necessary corporate, limited liability company or partnership action required on its part, and this Amendment and the Credit Agreement are the legal, valid and binding obligations of such Credit Party, enforceable against such Credit Party in accordance with their terms, except as their enforceability may be affected by the effect of bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights or remedies of creditors generally, and (c) no Default or Event of Default has occurred and is continuing.

     8. Counterparts.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN AND AMONG THE PARTIES.

     10. Guarantors. The Guarantors hereby consent to the execution of this Amendment by the Borrower and reaffirm their guaranties of all of the obligations of the Borrower to the Lenders. Borrower and Guarantors acknowledge and agree that the renewal, extension and amendment of the Credit Agreement shall not be considered a novation of account or new contract but that all existing rights, titles, powers, and estates in favor of the Lenders constitute valid and existing obligations in favor of the Lenders. Borrower and Guarantors each confirm and agree that (a) neither the execution of this Amendment or any other Loan Document nor the consummation of the transactions described herein and therein shall in any way effect, impair or limit the covenants, liabilities, obligations and duties of the Borrower and the Guarantors under the Loan Documents, and (b) the obligations evidenced and secured by the Loan Documents continue in full force and effect. Each Guarantor hereby further confirms that it unconditionally guarantees to the extent set forth in the Credit Agreement the due and punctual payment and performance of any and all amounts and obligations owed to the Lenders under the Credit Agreement or the other Loan Documents.
