The provisions of this Section shall constitute a continuing offer made for the benefit of and to all Secured Parties, and each Secured Party is hereby irrevocably authorized to enforce such provisions.

(b) No Subordinated Debtor shall make, and no Subordinated Creditor shall receive or accept from any Obligor, any payment in respect of any Intercompany Subordinated Debt if any Default of the nature set forth in Section 8.1.1 or Section 8.1.9 of the Credit Agreement, or any other Event of Default, shall have occurred and be continuing or would result therefrom.

(c) Subject to the provisions of this Subordination Agreement and the Credit Agreement, the Subordinated Debtors will be permitted to make, and the Subordinated Creditors will be entitled to receive and retain, payments on the Intercompany Subordinated Debt.

SECTION 2.2. In Furtherance of Subordination.

(a) Upon any distribution of all or any of the assets of any Subordinated Debtor or any Subordinated Creditor in the event of:

(iii) any assignment for the benefit of creditors or any other marshaling of assets and liabilities of such Subordinated Debtor or such Subordinated Creditor,

then, and in any such event, unless the Administrative Agent (at the direction of the Required Lenders) shall otherwise agree in writing, the Administrative Agent shall receive payment in full of all amounts due or to become due (whether or not the Senior Indebtedness has been declared due and payable prior to the date on which the Senior Indebtedness would otherwise have become due and payable) on or in respect of all Senior Indebtedness (including post-petition interest, whether or not allowed as a claim) before the Subordinated Creditors or anyone claiming through or on their behalf (including any receiver, trustee, or otherwise) are entitled to receive any payment on account of principal of (or premium, if any) or interest on or other amounts payable in respect of the Intercompany Subordinated Debt, and to that end, any payment or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in respect of the Intercompany Subordinated Debt in any such case, proceeding, dissolution, liquidation or other winding up or event, shall be paid or delivered directly to the Administrative Agent for the application (in the case of cash) to, or as collateral (in the case of non-cash property or securities) for, the payment or prepayment of the Senior Indebtedness until the Loan Repayment Date.

(b) If any proceeding, liquidation, dissolution or winding up referred to in clause (a) above is commenced by or against any Subordinated Debtor or any Subordinated Creditor,

(i) the Administrative Agent is hereby irrevocably authorized and empowered (in its own name or in the name of such Subordinated Debtor, such Subordinated Creditor or otherwise), but shall have no obligation, to demand, sue for, collect and receive every payment or distribution in respect of the Intercompany Subordinated Debt above and give acquittance therefor and to file claims and proofs of claim and take such other action (including voting the Intercompany Subordinated Debt or enforcing any security interest or other lien securing payment of the Intercompany Subordinated Debt) as the Administrative Agent (or, in the absence of direction from the Administrative Agent, the other Secured Parties) may deem necessary or advisable for the exercise or enforcement of any of the rights or interests of the Secured Parties hereunder; provided, that in the event the Administrative Agent or the Secured Parties take such action, the Administrative Agent or the Secured Parties shall apply all proceeds first, to the payment of the costs of enforcement of this Subordination Agreement, and second, to the pro rata payment, prepayment and/or Cash Collateralization of the Senior Indebtedness as set forth in the Credit Agreement; and

(c) All payments or distributions of assets of any Subordinated Debtor, whether in cash, property or securities upon or with respect to the Intercompany Subordinated Debt which are received by the Subordinated Creditors contrary to the provisions of this Subordination Agreement or the Credit Agreement shall be received and held for the benefit of the Secured Parties, shall be segregated from other funds and property held in trust by the Subordinated Creditors and shall be forthwith paid over to the Administrative Agent in the same form as so received (with any necessary indorsement) to be applied, (in the case of cash) to, or held as collateral (in the case of noncash property or securities) for, the payment or prepayment of the Senior Indebtedness, whether matured or unmatured, in accordance with the terms of this Subordination Agreement and the Credit Agreement.

(d) The Administrative Agent is hereby authorized to demand specific performance of this Subordination Agreement, whether or not any Subordinated Debtor or any Subordinated Creditor shall have complied with any of the provisions hereof applicable to it, at any time when the Subordinated Creditors or any one of them shall have failed to comply with any of the provisions of this Subordination Agreement applicable to it. The Subordinated Creditors hereby irrevocably waive any defense (other than the defense of payment in full of the Senior Indebtedness) based on the adequacy of a remedy at law which might be asserted as a bar to such remedy of specific performance.

SECTION 2.3. No Enforcement or Commencement of Any Proceedings. Each Subordinated Creditor agrees that, until the Loan Repayment Date has occurred, it will not accelerate the maturity of the Intercompany Subordinated Debt, exercise any remedies (including the assertion of any claims, motions, objections or arguments) or commence, or join with any creditor other than the Secured Parties in commencing, any proceeding referred to in clause (a) of Section 2.2. The Subordinated Creditors also agree not to, directly or indirectly, whether in connection with an event or proceeding referred to in clause (a) of Section 2.2 or otherwise, take any action that would be in violation of, or inconsistent with, or result in a breach of, this Agreement or to challenge or contest (i) the validity, perfection, priority or enforceability of any Senior Indebtedness or the Liens held by the Administrative Agent, for the benefit of the Lenders, to secure the payment, performance or observance of all or any part of the Senior Indebtedness, (ii) the rights of the Lenders set forth in any of the Loan Documents with respect to any such Lien, or (iii) the validity or enforceability of any of the Loan Documents.

SECTION 2.4. Rights of Subrogation. The Subordinated Creditors agree that no payment or distribution to any of the Secured Parties pursuant to the provisions of this Subordination Agreement shall entitle the Subordinated Creditors to exercise any rights of subrogation in respect thereof until the Loan Repayment Date has occurred. The Subordinated

5

Creditors agree that the subordination provisions contained herein shall not be affected by any action, or failure to act, by any Secured Party which results, or may result, in affecting, impairing or extinguishing any right of reimbursement or subrogation or other right or remedy of the Subordinated Creditors against the Subordinated Debtors.
