Each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof”, “herein”, or words of like import shall mean and be a reference to the Credit Agreement as amended hereby, and each reference to the Credit Agreement in any other document, instrument or agreement executed and/or delivered in connection with the Credit Agreement shall mean and be a reference to the Credit Agreement as amended hereby.
7.2.    No Waiver.  Neither the execution by the Administrative Agent or the Lenders of this Sixth 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 Sixth Amendment or which may occur in the future under the Credit Agreement and/or the other Loan Documents, except as expressly provided in Section 4 hereof.  Similarly, nothing contained in this Sixth 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 expressly provided herein, waive, 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.

7.4.    Counterparts.  This Sixth 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 counterpart of a signature page of this Sixth Amendment by facsimile or other electronic transmission (e.g., .pdf) shall be effective as delivery of a manually executed counterpart of this Sixth Amendment.
7.5.    No Oral Agreement.  This written Sixth Amendment, the Credit Agreement and the other Loan Documents executed in connection herewith and therewith represent the final agreement between the parties hereto and thereto and may not be contradicted by evidence of prior, contemporaneous, or subsequent oral agreements of the parties.

7.8.    Severability.  Any provision of this Sixth Amendment or any other Loan Document 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.
7.9.    Successors and Assigns.  This Sixth Amendment shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns (in each case, as permitted by Section 12.04).
