GENERAL RELEASE AND INDEMNITY

Section 2.01 In consideration of, among other things, the Purchasers’ execution and delivery of this Agreement, each of the Issuer and the other Credit Parties, on behalf of itself and its agents, representatives, officers, directors, advisors, employees, subsidiaries, affiliates, successors and assigns (collectively, “Releasors”), hereby forever agrees and covenants not to sue or prosecute against any Releasee (as hereinafter defined) and hereby forever waives, releases and discharges each Releasee from any and all claims (including crossclaims, counterclaims, rights of set-off and recoupment), actions, causes of action, suits, debts, accounts, interests, liens, promises, warranties, damages and consequential damages, demands, agreements, bonds, bills, specialties, covenants, controversies, variances, trespasses, judgments, executions, costs, expenses or claims whatsoever, that such Releasor now has or hereafter may have, of whatsoever nature and kind, whether known or unknown, whether now existing or hereafter arising, whether arising at law or in equity (collectively, the “Claims”), against any or all of the Agent and Purchasers and their respective affiliates, subsidiaries, shareholders and “controlling persons” (within the meaning of the federal securities laws), and their respective permitted successors and assigns and each and all of the officers, directors, employees, agents, attorneys, advisors and other representatives of each of the foregoing (collectively, the “Releasees”), based in whole or in part on facts, whether or not now known, existing on or before the Effective Time, that relate to, arise out of or otherwise are in connection with: (i) any or all of the Note Documents or transactions contemplated thereby or any actions or omissions in connection therewith, (ii) any aspect of the dealings or relationships between or among the Issuer and the other Credit Parties, on the one hand, and any or all of the Agent and Purchasers, on the other hand, relating to any or all of the documents, transactions, actions or omissions referenced in clause (i) hereof, or (iii) any aspect of the dealings or relationships between or among any or all of Sponsor, on the one hand, and the Agent and Purchasers, on the other hand, but only to the extent such dealings or relationships relate to any or all of the documents, transactions, actions or omissions referenced in clause (i) hereof. The receipt by the Issuer or any other Credit Party of any Term Loans or other financial accommodations made by Agent

or any Purchaser after the date hereof shall constitute a ratification, adoption, and confirmation by such party of the foregoing general release of all Claims against the Releasees that are based in whole or in part on facts, whether or not now known or unknown, existing on or prior to the date of receipt of any such Term Loans or other financial accommodations. In entering into this Agreement, the Issuer and each other Credit Party consulted with, and has been represented by, legal counsel and expressly disclaims any reliance on any representations, acts or omissions by any of the Releasees and hereby agrees and acknowledges that the validity and effectiveness of the releases set forth above do not depend in any way on any such representations, acts and/or omissions or the accuracy, completeness or validity thereof.

Section 2.02 Each Credit Party agrees to indemnify, hold harmless and defend the Releasees in connection with this Agreement and the other documents and transactions contemplated hereby or related hereto, including Attorney Costs, all as provided in, and to the extent required by, Section 9.6 of the Note Agreement; provided, however, the Credit Parties agree that the Agent’s and Purchasers’ entering into and complying with the terms of this Agreement shall not constitute bad faith, gross negligence or willful misconduct.
