Each Loan Party acknowledges and agrees that, except as expressly set forth herein, each of the Loan Documents to which it is a party or otherwise bound shall continue in full force and effect and that, except as expressly set forth herein, all of its obligations thereunder shall be valid and enforceable and shall not be impaired or limited by the execution or effectiveness of this Waiver and Amendment.

As waived and amended hereby, the Credit Agreement remains in full force and effect. Upon the effectiveness of this Waiver and Amendment, each reference in the Credit Agreement and in any exhibits attached thereto to “this Agreement”, “hereunder”, “hereof”, “herein” or words of similar import shall mean and be a reference to the Credit Agreement as amended and waived hereby.
