B. Illegality. In case any one or more of the provisions contained in this Amendment should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.

C. Changes in Writing. No modification, amendment or waiver of any provision of this Amendment nor consent to any departure by the Borrower or any of the Guarantors therefrom, will in any event be effective unless the same is in writing and signed by the Agent Bank, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

D. Successors and Assigns. This Amendment will be binding upon and inure to the benefit of the Borrower, the Guarantors, the Agent Bank and the Banks and their respective successors and assigns; provided, however, that neither the Borrower nor the Guarantors may assign this Amendment in whole or in part without the prior written consent of the Agent Bank, and the Agent Bank and the Banks at any time may assign this Amendment in whole or in part, as provided in Section 11 of the Loan Agreement.
