Section 5. Miscellaneous.

5.1 Confirmation. The provisions of the Credit Agreement (as amended by this Seventh Amendment) shall remain in full force and effect in accordance with its terms following the effectiveness of this Seventh Amendment. This Seventh Amendment shall constitute a Loan Document.

5.2 No Waiver. Neither the execution by the Administrative Agent or the Lenders party hereto of this Seventh Amendment, nor any other act or omission by the Administrative Agent or the Lenders or their officers in connection herewith, shall be deemed a waiver by the Administrative Agent or the Lenders of any Defaults or Events of Default which may exist, which may have occurred prior to the date of the effectiveness of this Seventh Amendment or which may occur in the future under the Credit Agreement and/or the other Loan Documents.

Similarly, nothing contained in this Seventh Amendment shall directly or indirectly in any way whatsoever either: (a) impair, prejudice or otherwise adversely affect the Administrative Agent’s or the Lenders’ right at any time to exercise any right, privilege or remedy in connection with the Loan Documents with respect to any Default or Event of Default, (b) except as provided herein, amend or alter any provision of the Credit Agreement, the other Loan Documents, or any other contract or instrument, or (c) constitute any course of dealing or other basis for altering any obligation of the Borrower or any right, privilege or remedy of the Administrative Agent or the Lenders under the Credit Agreement, the other Loan Documents, or any other contract or instrument. Nothing in this Seventh Amendment shall be construed to be a consent by the Administrative Agent or the Lenders to any Default or Event of Default. Each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof”, “herein” or any other word or words of similar import shall mean and be a reference to the Credit Agreement as amended hereby, and each reference in any other Loan Document to the Credit Agreement or any word or words of similar import shall be and mean a reference to the Credit Agreement as amended hereby.

5.3 Counterparts. This Seventh Amendment may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed signature page to this Seventh Amendment by facsimile transmission or other electronic transmission (including .pdf) shall be as effective as delivery of a manually executed counterpart of this Seventh Amendment.

5.4 Successors and Assigns. This Seventh Amendment shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.

5.5 Severability. Any provision of this Seventh Amendment held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

5.6 No Oral Agreement. This Seventh Amendment, the Credit Agreement and the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties hereto relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. This Seventh Amendment, the Credit Agreement and the other Loan Documents represent the final agreement among the parties hereto and thereto and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties.

5.7 Governing Law. THIS SEVENTH AMENDMENT (INCLUDING, BUT NOT LIMITED TO, THE VALIDITY AND ENFORCEABILITY HEREOF) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

IN WITNESS WHEREOF, the parties hereto have caused this Seventh Amendment to be duly executed effective as of the date first written above.
