13.7 Proof of Claim. Each holder of Subordinated Debt irrevocably authorizes and empowers the holders of Senior Financing and the Senior Term C Loans and each holder of Junior Subordinated Notes irrevocably authorizes and empowers the holders of Senior Subordinated Notes in any proceeding under any federal or state bankruptcy or insolvency law, or any other reorganization, dissolution or liquidation proceedings of the Company to file a proof of claim on behalf of such holder of Subordinated Debt or Junior Subordinated Notes, as the case may be, with respect to the Subordinated Debt or the Junior Subordinated Notes, as the case may be, and the other amounts owing hereunder and the Notes if (and only if) such holder of Subordinated Debt or Junior Subordinated Notes, as the case may be, fails to file proof of its claims prior to ten (10) days before the expiration of the time period during which such proof of claim must be filed. Neither this Section

13.7, nor any other provisions hereof, shall be construed to give the holders of Senior Financing or the Senior Term C Loans any right to vote any Subordinated Debt or the holders of Senior Subordinated Notes any right to vote any Junior Subordinated Notes, or any related claim, whether in connection with any resolution, arrangement, plan of reorganization, compromise, settlement, election, or otherwise.

In the event that any Subordinated Debt shall be declared due and payable as the result of the occurrence of any one or more Events of Default in respect thereof, under circumstances when the terms of Section 13.2 or 13.3 do not prohibit payment on Subordinated Debt, no payment shall be made in respect of any Subordinated Debt unless and until all Senior Financing and the Senior Term C Loans shall have been paid in full in cash or such declaration and its consequences shall have been rescinded and all such Defaults and Events of Default shall have been remedied or waived or shall have ceased to exist. In the event that any Junior Subordinated Notes shall be declared due and payable as the result of the occurrence of any one or more Events of Default in respect thereof, under circumstances when the terms of Section 13.4 do not prohibit payment on Junior Subordinated Notes, no payment shall be made in respect of any Junior Subordinated Notes unless and until all Senior Subordinated Notes shall have been paid in full in cash or such declaration and its consequences shall have been rescinded and all such Defaults and Events of Default shall have been remedied or waived or shall have ceased to exist.

13.9 Turnover of Payments.

(ii) Agent or the Senior Agent shall have notified such holders of Subordinated Debt, within one hundred eighty (180) days of any such payment or distribution, of the facts by reason of which such collection or receipt so contravenes this Article 13;

then such holders of Subordinated Debt will deliver such payment or distribution, to the extent necessary to pay all such Senior Financing or Senior Term C Loans in full in cash, to the holders of such Senior Financing or Senior Term C Loans and, until so delivered, the same shall be held in trust by such holders of Subordinated Debt as the property of the holders of such Senior Financing or Senior Term C Loans. If after any amount is delivered pursuant to this Section 13.9(a), whether or not such amounts have been applied to the payment of Senior Financing or the Senior Term C Loans, and the outstanding Senior Financing or the Senior Term C Loans shall thereafter be paid in full in cash by the Company or otherwise other than pursuant to this Section 13.9(a), the holders of Senior Financing or the Senior Term C Loans shall return to such holders of Subordinated Debt an amount equal to the amount delivered to such holders of Senior Financing or the Senior

Term C Loans pursuant to this Section 13.9(a). Any optional prepayment made in respect of the Subordinated Debt that violates this Agreement shall also be subject to this Section 13.9(a).

(b) If:

(i) any payment or distribution shall be collected or received by any holders of Junior Subordinated Notes in contravention of any of the terms of this Article 13 and prior to the payment in full in cash of the Senior Subordinated Notes at the time outstanding; and

(ii) the Agent shall have notified such holders of Junior Subordinated Notes, within one hundred eighty (180) days of any such payment or distribution, of the facts by reason of which such collection or receipt so contravenes this Article 13;

then such holders of Junior Subordinated Notes will deliver such payment or distribution, to the extent necessary to pay all such Senior Subordinated Notes in full in cash, to the holders of such Senior Subordinated Notes and, until so delivered, the same shall be held in trust by such holders of Junior Subordinated Notes as the property of the holders of such Senior Subordinated Notes. If after any amount is delivered to the holders of Senior Subordinated Notes pursuant to this Section 13.9(b), whether or not such amounts have been applied to the payment of Senior Subordinated Notes, and the outstanding Senior Subordinated Notes shall thereafter be paid in full in cash by the Company or otherwise other than pursuant to this Section 13.9(b), the holders of Senior Subordinated Notes shall return to such holders of Junior Subordinated Notes an amount equal to the amount delivered to such holders of Senior Subordinated Notes pursuant to this Section 13.9(b).

13.10 Obligations Not Impaired.

(a) No Impairment of Senior Financing or Senior Term C Loans. No right of any present or future holder of any Senior Financing or Senior Term C Loans and no right of any present or future holder of any Senior Subordinated Notes to enforce the subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any non-compliance by the Company with the terms, provisions and covenants of this Agreement, regardless of any knowledge thereof any such holder may have or be otherwise charged with.

(b) No Impairment of Subordinated Debts. Nothing contained in this Section 13.10 shall impair, as between the Company and any holder of Subordinated Debt, the obligation of the Company to pay to such holder the principal thereof and prepayment premium, if any, and interest thereon as and when the same shall become due and payable in accordance with the terms of this Agreement, or prevent any holder of any Subordinated Debt from exercising all rights, powers and remedies otherwise permitted by applicable law or under this Agreement or the Stockholders Agreement, all subject to the rights of the holders of the Senior Financing and the Senior Term C Loans to receive cash,

Securities or other property otherwise payable or deliverable to the holders of Subordinated Debt.
