SECTION 6.  Release. Each of the Transaction Parties hereby absolutely and unconditionally releases and forever discharges each Purchaser, and any and all participants, parent corporations, subsidiary corporations, affiliated corporations, insurers, indemnitors, successors and assigns thereof, together with all of the present and former directors, officers, agents and employees of any of the foregoing, from any and all claims, counterclaims, demands or causes of action of any kind, nature or description, whether arising in law or equity or upon contract or tort or under any state or federal law or otherwise, which such Transaction Party has had, now has or has made claim to have against any such person for or by reason of any act, omission, matter or cause arising from the Note Agreement or any other Note Document on or prior to the date of this letter, whether such claims, counterclaims, demands or causes of action are matured or unmatured or known or unknown.

The Transaction Parties hereby confirm their obligations under the Note Agreement, whether or not the transactions hereby contemplated are consummated, to pay, promptly after request by any holder of the Notes, all reasonable out-of-pocket costs and expenses, including attorneys’ fees and expenses, incurred by any holder of the Notes in connection with this letter agreement or the transactions contemplated hereby, in enforcing any rights under this letter agreement, or in responding to any subpoena or other legal process or informal investigative demand issued in connection with this letter agreement or the transactions contemplated hereby, in each case in accordance with the Note Agreement. The obligations of the Transaction Parties under this Section 7 shall survive transfer by any holder of any Note and payment of any Note.

Each Transaction Party hereby acknowledges that, notwithstanding the foregoing modifications, that the Note Agreement remains in full force and effect and is hereby ratified and confirmed, in all respects, in each case, as may be amended by this letter agreement. The execution of this letter agreement shall not operate as a novation, waiver of any right, power or remedy of any holder of any Note, nor constitute a waiver of any provision of any of the Note Documents.
