Borrower may not assign this Amendment or any rights or duties hereunder without the Lenders’ prior written consent and any prohibited assignment shall be absolutely void ab initio.

6.    Reaffirmation. Except as expressly set forth in Section 2 hereof, the execution, delivery, and performance of this Amendment shall not alter, modify, amend, or in any way affect any of the terms, conditions, obligations, covenants, or agreements contained in the Loan Agreement or any other Loan Document, and shall not operate as a waiver of any right, power, or remedy of Agent or any Lender under the Loan Agreement or any other Loan Document.

Nothing in this Amendment shall constitute a satisfaction of Borrower’s Obligations. This Amendment shall be deemed to be one of the Loan Documents for all purposes of the Loan Agreement and the other Loan Documents, and all references in the Loan Documents to the Loan Agreement shall be deemed to be references to the Loan Agreement as amended hereby. Agent and Lender reserve all rights, privileges and remedies under the Loan Documents. Except as amended hereby, the Loan Agreement and other Loan Documents remain unmodified and in full force and effect.

8.    Miscellaneous. Borrower acknowledges and agrees that the representations and warranties set forth herein are material inducements to Agent and the Lenders to deliver this Amendment. The provisions of Sections 11.3, 13, 17.1 through 17.5 and 17.10 of the Loan Agreement are hereby incorporated by reference and shall be as effective with respect to this Amendment as if such provisions were included herein in their entirety.
