Annex A - 3

OF AFFILIATE] with the terms and provisions and covenants herein regardless of any knowledge thereof the Collateral Agent or any other such Secured Party or other holder may have or otherwise be charged with.

[INSERT NAME OF AFFILIATE] will not ask, demand, sue for, take or receive from the Company, directly or indirectly, in cash, property or securities or by set off or in any other manner (including, without limitation, from or by way of attachment or seizure of or foreclosure upon any property or assets of the Company which may now or hereafter constitute collateral for any Subordinated Debt), payment of all or any part of the Subordinated Debt if an Event of Default shall have occurred and be continuing under the Outstanding Agreements or under any other agreement or instrument evidencing or securing the Senior Debt unless and until all Senior Debt shall have been irrevocably paid in full in cash or the benefits of this sentence waived by or on behalf of the Creditors or the other holder or holders of the Senior Debt.

Annex A - 4

Section 8. Subrogation. [INSERT NAME OF AFFILIATE] shall be subrogated to the rights of the holders of the Senior Debt to receive payments or distributions of assets of the Company applicable to the Senior Debt until all amounts owing on the Subordinated Debt have been paid in full; provided that [INSERT NAME OF AFFILIATE] shall not enforce any payment by way of subrogation (whether contractual, under Section 509 of the United States Bankruptcy Code or otherwise) until all amounts payable under or with respect to the Senior Debt have been irrevocably paid in full in cash. For the purposes of the rights of subrogation set forth in this Section 8, no payments or distributions to any Secured Party or other holder or holders of the Senior Debt of any cash, property or securities to which [INSERT NAME OF AFFILIATE] would be entitled but for the provisions of this Annex A, and no payments over pursuant to the provisions of this Annex A to any Secured Party or holder or other holders of the Senior Debt by [INSERT NAME OF AFFILIATE], shall, as among the Company, its creditors (other than the Secured Parties and any other holder or holders of the Senior Debt) and [INSERT NAME OF AFFILIATE], be deemed to be a payment or distribution by the Company to or on account of the Senior Debt, it being understood that the provisions of this Annex A are solely for the purpose of defining the relative rights of the Secured Parties or any other holder or holders of the Senior Debt and [INSERT NAME OF AFFILIATE].

If any payment or distribution to which [INSERT NAME OF AFFILIATE] would otherwise have been entitled but for the provisions of this Annex A shall have been applied, pursuant to the provisions of this Annex A, to the payment of all amounts payable under the Senior Debt, then [INSERT NAME OF AFFILIATE] shall be entitled to receive from the Secured Parties or other holder or holders of the Senior Debt at the time outstanding any payments or distributions received by the Secured Parties or such holder or holders of the Senior Debt in excess of the amount sufficient to irrevocably pay all amounts under or in respect of the Senior Debt in full in cash.

If any applicable provisions of the Uniform Commercial Code as in effect in the State of New York or any other relevant jurisdiction (the “UCC”) requires the Collateral Agent or any other Secured Party or holder of the Senior Debt or any representative thereof to notify [INSERT NAME OF AFFILIATE] that the Collateral Agent or such other Secured Party or holder or representative thereof will foreclose or otherwise realize upon any collateral or other property provided to secure the Senior Debt, whether pursuant to Article 9 of the UCC or otherwise, [INSERT NAME OF AFFILIATE] hereby waives, to the extent permitted by applicable law, all such required notice(s) and, to the extent such requirement of notice may not be waived under applicable law, agrees that five Business Days’ written notice of any such foreclosure or other realization shall be commercially reasonable [INSERT NAME OF AFFILIATE] further waives, to the extent permitted by applicable law, any and all rights it may have to require the Collateral Agent or any other Secured Party or other holder of the Senior Debt or representative thereof to marshal any collateral or other property provided as security for the Senior Debt and any and all other rights and remedies now or hereafter available to [INSERT NAME OF AFFILIATE] under Section 9-611 of the UCC. [INSERT NAME OF AFFILIATE] agrees that the Collateral Agent and any other Secured Party or holder of the Senior Debt or representative thereof may sell inventory that constitutes collateral or other security for any Senior Debt pursuant to a repurchase agreement, that such sale shall not be deemed a transfer subject to Section 9-618 of the UCC or any similar provisions of any other applicable law (such provisions, to the extent otherwise applicable to such sale, being hereby waived), and that the repurchase of inventory by a seller under a repurchase agreement shall be a commercially reasonable method of disposition.

[INSERT NAME OF AFFILIATE] may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of [INSERT NAME OF AFFILIATE] allowed in any judicial proceedings relative to the Company, its creditors or its property. If [INSERT NAME OF AFFILIATE] files any claim, proof of claim or similar instrument in any judicial proceeding referred to above and all Senior Debt has not been irrevocably paid in full in cash, [INSERT NAME OF AFFILIATE] shall (i) file such claim, proof of claim or similar instrument on behalf of the Secured Parties and the other holder or holders of the Senior Debt as such Secured Parties’ or other holder’s or holders’ interests may appear and (ii) take all such other actions as may be appropriate to ensure that all payments and distributions made in respect of any such proceedings are made to the Collateral Agent or the other Secured Parties, as applicable, and any other holder or holders of the Senior Debt as its or their interests may appear.

[INSERT NAME OF AFFILIATE] hereby appoints the Collateral Agent or other holder or holders of the Senior Debt or representatives thereof as its agent(s) and attorney(s) in fact, all acts of such attorney(s) being hereby ratified and confirmed and such appointment(s), being coupled with an interest, being irrevocable until the Senior Debt is irrevocably paid in full in cash, to exercise the rights and file the claims referred to in this Section 10 and to execute and deliver any documentation necessary for the exercise of such rights or to file such claims. Notwithstanding anything to the contrary contained herein, [INSERT NAME OF AFFILIATE] shall not file any claim or take any action which competes or interferes with the rights and interests of the Secured Parties or any other holders of the Senior Debt under the Outstanding Agreements, any other Financing Document or any other agreement or instrument evidencing or securing the Senior Debt. Until the Senior Debt has been irrevocably paid in full in cash, [INSERT NAME OF AFFILIATE] will not (in any proceeding

Annex A - 6

of the type described in Section 3(a)) discharge all or any portion of the obligations of the Company in respect of the Subordinated Debt, whether by forgiveness, receipt of capital stock, exercise of conversion privileges or otherwise, without the prior written consent of the Collateral Agent or the Secured Parties, as applicable, or the holder or holders of the Senior Debt.

Section 11. Obligation of the Company Unconditional.

Upon any distribution of assets of the Company referred to in this Annex A, [INSERT NAME OF AFFILIATE] shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding up, liquidation or reorganization proceedings are pending, or a certificate of the liquidating trustee or agent or other Person making any distribution to [INSERT NAME OF AFFILIATE], for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Annex A.

Section 12. Reinstatements in Certain Circumstances. If, at any time, all or part of any payment with respect to Senior Debt theretofore made by the Company or any other Person is rescinded or must otherwise be returned by the holders of Senior Debt for any reason whatsoever (including, without limitation, the insolvency, bankruptcy or reorganization of Company or such other Persons), the subordination provisions set forth herein shall continue to be effective or be reinstated, as the case may be, all as though such payment had not been made.
