Exhibit A

Schedule 8

Terms of Subordination

1. General.

(a) Unless otherwise expressly provided hereunder, payment of the principal of Permitted Indebtedness under clause (j) of such definition (“Subordinated Indebtedness”) and other amounts payable on or in respect of Subordinated Indebtedness shall be subordinate and subject in right of payment to the prior payment in full of all Guaranteed Obligations (including without limitation post-petition interest and postpetition fees and costs, whether or not allowable in bankruptcy, but excluding certain indemnity or reimbursement obligations that survive the repayment in full of the underlying Loans and for which no claim has been asserted) (“Payment in Full”). Subordinated Indebtedness (excluding interest paid in kind) shall be not incurred if the principal amount thereof will exceed the applicable aggregate maximum indebtedness set forth in clause (j) of the definition of Permitted Indebtedness.

(b) Any lender supplying Subordinated Indebtedness (each, in such capacity, a “Subordinated Lender”) agrees that, unless and until Payment in Full, such Subordinated Lender shall not ask, demand, sue for, take or receive from, by set-off or in any other manner, or retain, payment (in whole or in part) of its Subordinated Indebtedness from the Guarantor except (i) as permitted under these subordination provisions and (ii) if no Event of Default under the Guaranty would result from such a payment.

(c) Each Subordinated Lender agrees that the Guarantor shall make Payment in Full prior to the payment of principal of its Subordinated Indebtedness, except as permitted pursuant to Section 4 hereof.

(d) Notwithstanding anything to the contrary contained in this Guaranty, the Guarantor may pay outstanding principal, together with accrued and unpaid interest and fees then due, in respect of any Subordinated Indebtedness (the “Original Debt”) from the proceeds of any new Subordinated Indebtedness incurred to refinance or replace such Original Debt.

2. Subordinated Maturity Date. The maturity date of any Subordinated Indebtedness shall be no earlier than December 31, 2011, which date shall be extended to a date that is no less than 91 days after any new maturity date of the Guaranteed Obligations (the “Subordinated Maturity Date”).

3. Interest; Subordinated Payments. No part of the principal of any Subordinated Indebtedness shall be repaid before the earlier to occur of the Payment in Full of the Guaranteed Obligations or the Subordinated Maturity Date therefor, unless otherwise permitted under Section 4 of this Schedule 8. The aggregate amount of interest required to be paid in cash in respect of any Subordinated Indebtedness shall not over any twelve (12) consecutive month period exceed an aggregate amount equal to 13% of the outstanding principal amount of such Subordinated Indebtedness accrued over such 12-month period, inclusive of any and all fees payable in connection with such Subordinated Indebtedness (with original issue discount and fees being equated to interest based on a weighted average life to maturity of the Subordinated Indebtedness); provided, that any interest payable in respect of the Subordinated Indebtedness that will exceed such limitations set forth above shall not be paid unless and until a holder of membership interests in the Guarantor or one or more of such holder’s Affiliates performs any of the following:

(a) makes a cash equity capital contribution to the Guarantor in the form of Cure Equity in the amount of such excess interest; or

(b) makes a subordinated loan to the Guarantor in the form of Cure Debt in an amount of such excess interest.

For purposes of the foregoing, the following terms shall have the corresponding meanings:

“Cure Debt” shall mean Indebtedness issued by the Guarantor to the holders of membership interests in the Guarantor or any of their Affiliates (a) that is subordinated to the Guaranteed Obligations and in accordance with the terms set forth on this Exhibit A, and (b) that has no principal amortization, mandatory redemption, interest payment payable in cash or other cash payment requirements prior to the date that is six (6) months after the scheduled maturity date of the Guaranteed Obligations.

“Cure Equity” shall mean membership interests in and issued by the Guarantor for cash to the holders of membership interests in the Guarantor or any of their Affiliates and (a) contain no requirement to be purchased, redeemed, retired or defeased (or any similar requirement) or the payment of any cash dividend, prior to date that is six (6) months after the scheduled maturity date of the Guaranteed Obligations and (b) are not subject to any mandatory cash dividend or distribution requirements prior to the date that is six (6) months after the scheduled maturity date of the Guaranteed Obligations (except for Tax Distributions).

4. Principal Payments. The Guarantor agrees that unless and until Payment in Full, it shall not make (or cause to be made) any cash payment of

principal on or in respect of any Subordinated Indebtedness to any Subordinated Lender, except that such payments may be made (x) to the extent permitted by Section 1(d) of this Schedule 8 or (y) from funds of the Guarantor that are available to make a Restricted Payment in accordance with and to the extent permitted by Section 3(aa) of the Guaranty.

5. Payment Upon Dissolution, Etc. In the event of (a) any insolvency or bankruptcy case or proceeding or any receivership, liquidation, reorganization or other similar proceeding in connection therewith, relative to the Guarantor, or (b) any liquidation, dissolution or other winding up of the Guarantor, whether partial or complete and whether voluntary or involuntary and whether or not involving insolvency or bankruptcy or (c) any assignment for the benefit of creditors or any other marshaling of assets and liabilities of the Guarantor, then and in any such proceeding, dissolution, liquidation or other winding up or other event, the Lender shall be entitled to receive Payment in Full before any Subordinated Lender shall be entitled to receive any payment on account of its Subordinated Indebtedness (whether in respect of principal, interest, premium, fees, indemnities, commissions or otherwise) 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 its Subordinated Indebtedness in any such case, proceeding, dissolution, liquidation or other winding up or event shall instead be paid or delivered directly to the Lender (or to the applicable agent on behalf of the Lender) for application to the Guaranteed Obligations in accordance with the Guaranty, whether or not due, until Payment in Full.

6. Proceeding Against Borrowers. Upon the occurrence of an Event of Default giving rise to the Lender’s rights to make a demand on the Guarantor for payment of all of the Guaranteed Obligations, no payments of any kind in respect of any Subordinated Indebtedness shall be permitted and all interest thereafter accruing on the Permitted Indebtedness shall be capitalized and added to the principal balance on the Permitted Indebtedness that shall be due and payable no earlier than the Subordinated Maturity Date thereof. Whether or not any Event of Default shall exist under the Guaranty, each Subordinated Lender shall not, without the prior written consent of the Lender, (a) commence an involuntary proceeding against the Guarantor under a bankruptcy, insolvency or receivership law or (b) take any grant of collateral security for its Subordinated Indebtedness, which collateral security also has been pledged as security for the Guaranteed Obligations.

7. Payment to Lenders of Certain Amounts Received by each Subordinated Lender. In the event that any Subordinated Lender receives on account or in respect of its Subordinated Indebtedness any distribution of assets by the Guarantor or any Affiliate, or payment by or on behalf of the Guarantor or any Affiliate, of any kind or character, whether in cash, securities or other

property, other than as permitted hereunder, each Subordinated Lender shall hold in trust (as property of the Lender) for the benefit of, and immediately upon receipt thereof, shall pay over or deliver to the Lender (or to the applicable agent on behalf of the Lender) such distribution or payment in precisely the form received (except for the endorsement or assignment by such Subordinated Lender where necessary) for application in accordance with the Guaranty. In the event of failure of such Subordinated Lender to make any such endorsement or assignment, the Lender irrevocably is authorized and empowered by and on behalf of each Subordinated Lender to make the same.

8. Authorizations to Lender. Each Subordinated Lender (a) irrevocably authorizes and empowers (without imposing any obligation on) the Lender (or applicable agent on behalf of the Lender) to demand, sue for, collect, receive and give receipts for all payments and distributions on or in respect of its Subordinated Indebtedness which are required to be paid or delivered to the Lender (or the applicable agent on behalf of the Lender) as provided herein, and to file and prove all claims therefor and take all such other action, in the name of such Subordinated Lender or otherwise, as the Lender (or applicable agent on behalf of the Lender) may determine to be necessary or appropriate for the enforcement of these subordination provisions, all in such manner as the Lender shall instruct or otherwise in accordance with the Guaranty, (b) irrevocably authorizes and empowers (without imposing any obligation) the Lender to vote the (including, without limitation, voting its Subordinated Indebtedness in favor of or in opposition to any matter which may come before any meeting of creditors of the Guarantor generally or in connection with, or in anticipation of, any insolvency or bankruptcy case or proceeding, or any proceeding under any laws relating to the relief of debtors, readjustment of indebtedness, arrangements, reorganizations, compositions or extensions relative to the Guarantor) in such manner as the Lender shall instruct or otherwise in accordance with the Guaranty, and (c) agrees to execute and deliver to the Lender (or applicable agent on behalf of the Lender) all such further instruments confirming the above authorization, and all such powers of attorney, proofs of claim, assignments of claim and other instruments, and to take all such other action, as may be requested by the Lender in order to enable the Lender (or the applicable agent on behalf of the Lender) to enforce all claims upon or in respect of its Subordinated Indebtedness.

9. Notice. Each Subordinated Lender agrees, for the benefit of the Lender, that it will give the Lender (or the applicable agent on behalf of the Lender) prompt notice of any event of default (as defined under the terms of its Subordinated Indebtedness) by the Guarantor or any Affiliate in respect of any Subordinated Indebtedness.

10. No Waiver; Modification to Senior Debt. No failure on the part of the Lender (or applicable agent on behalf of the Lender) and no delay in

exercising, any right, remedy or power hereunder shall operate as a waiver thereof by the Lender, nor shall any single or partial exercise of any right, remedy or power hereunder preclude any other or future exercise by the Lender (or applicable agent on behalf of the Lender) of any other right, remedy or power. Each and every right, remedy and power granted, by law or other agreement, or allowed to the Lender shall be cumulative and not exclusive, and may be exercised by the Lender (or applicable agent on behalf of the Lender) from time to time.

At any time, without the consent of or notice to the Subordinated Lenders, without incurring responsibility or liability to the Subordinated Lenders and without impairing or releasing the subordination provided herein or the obligations hereunder of the Subordinated Lenders, the Lender may do anyone or more of the following: (a) change the manner, place or terms of payment of or extend the time of payment of, or renew or alter, the Guaranteed Obligations or any collateral security therefor, or otherwise amend or supplement in any manner the Guaranteed Obligations or any instruments evidencing the same or any agreement under which Guaranteed Obligations are outstanding or the Guaranty; (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing the Guaranteed Obligations; (c) release any Person liable in any manner for the Guaranteed Obligations; and (d) exercise or refrain from exercising any rights against the Guarantor and any other Person. Each Subordinated Lender unconditionally waives notice of the incurring of Guaranteed Obligations or any part thereof.

11. Further Assurances. Each Subordinated Lender, at its own cost, shall take any further action as the Lender may reasonably request in order to carry out more fully the intent and purpose of these subordination provisions, including the undertaking any other further actions deemed advisable or reasonably required under the laws of the local jurisdiction to effect the enforceability of these subordination provisions thereunder.
