C. Representations and Warranties. All representations and warranties contained herein or in the other Modification Papers or otherwise made in writing in connection herewith or therewith shall be true and correct in all material respects (provided that any such representations or warranties that are, by their terms, already qualified by reference to materiality shall be true and correct without regard to such materiality standard) with the same force and effect as though such representations and warranties have been made on and as of the Effective Date, or if made as of a specific date, as of such date.

3. Amendments to Original Credit Agreement. On the Effective Date, the Original Credit Agreement shall be deemed to be amended as follows:

(a) Section 4.05 of the Original Credit Agreement is hereby amended by adding the following at the end of paragraph (e) thereof:

5. No Further Amendments. Except as previously amended or waived in writing or as amended hereby, the Original Credit Agreement shall remain unchanged and all provisions shall remain fully effective between the parties.
