after the date hereof) for each of the twenty (20) Trading Days preceding the date of such request and (y) as of each such Trading Day and the date of such request, the Company has then filed all required reports under Section 13 or 15(d), as applicable, of the Exchange Act; and (ii) if the Intercreditor Agreement is then in effect, but the prohibition therein on any cash Optional Redemption Payment has been waived by the First Lien Agent and any Optional Redemption Payment becomes due under the Sixth Second Lien Note prior to the first anniversary of the date hereof, then the New Buyer (or any such assignee) may convert such Optional Redemption Payment without the prior written consent of the First Lien Agent; (b) the New Buyer shall not sell or otherwise assign the Sixth Second Lien Note to any other person unless such assignee shall have confirmed in writing to the Company and the First Lien Agent that it is bound by the terms of this Section 4; (c) the First Lien Agent shall be a third-party beneficiary of the agreements in this Section 4; (d) the rights of the First Lien Agent under this Section 4 may not be waived without the prior written consent of the First Lien Agent; and (e) in addition to the requirements of Section 6(e) of the Securities Purchase Agreement, this Section 4 may not be amended or otherwise modified except with the prior written consent of the First Lien Agent.

5.    Without limiting the generality of the foregoing, the New Buyer hereby makes and undertakes, as the case may be, on and as of the date hereof, all covenants, agreements and representations and warranties of a Buyer contained in the Securities Purchase Agreement, to the extent applicable to the New Buyer, and agrees to be bound by all such covenants, agreements and representations and warranties.

6.    The New Buyer and the Agent (each a “Note Party”), each hereby unconditionally and irrevocably releases, and fully and forever acquits and discharges the Company, all its subsidiaries and other affiliates and their respective officers, servants, employees, agents, attorneys, principals, directors and shareholders, and their respective heirs, legal representatives, successors and assigns (collectively, the “Released Parties”), from any and all claims, demands, causes of action, obligations, remedies, suits, damages and liabilities (collectively, the “Claims”), of any nature whatsoever, whether now known, suspected or claimed, whether arising under common law, in equity or under statute, which any Note Party ever had or now has against any Released Party which may have arisen at any time on or prior to the date of this Agreement and which were in any manner related to any of the following transactions (collectively, the “Transactions”): (a) the transactions contemplated by the Transaction Documents or (b) the issuance of any shares of Series C Preferred Stock to such Note Party or any of its affiliates; provided that, for the avoidance of doubt, the Company shall not be released in respect of any Transactions occurring on or after the date of this Agreement under the Transaction Documents or otherwise.
