2.02                        Actions upon Dissolution.  In the event of any Insolvency Proceeding, then upon any payment or distribution of assets of any Obligor of any kind or character, whether in cash, property or securities, to any of its creditors (including without limitation the Subordinated Creditors) the Discharge of ABL Obligations shall occur first before the holders of the Subordinated Indebtedness shall be entitled to retain any assets (other than Exempt Last Out Loan Proceeds) so paid or distributed in respect of the Subordinated Indebtedness (for principal, premium, interest or otherwise) and, to that end, the holders of the ABL Obligations shall be entitled to receive for application in payment thereof any payment or distribution of any kind or character (other than Exempt Last Out Loan Proceeds as provided in Sections 4.15(h) and 11.5 of the ABL Credit Agreement), whether in cash or property or securities that would, but for these Subordination Terms, be paid or delivered to the Subordinated Creditors.  The Subordinated Creditors shall provide to the ABL Agent (on behalf of the ABL Secured Parties) all information and documents necessary to present claims or seek enforcement with respect to the Subordinated Indebtedness and will duly and promptly take such action as the ABL Agent (on behalf of the ABL Secured Parties) may request (i) to collect the Subordinated Indebtedness for the account of the ABL Agent (on behalf of the ABL Secured Parties), other than Exempt Last Out Loan Proceeds, and (ii) to file appropriate claims or proofs of claim with respect thereto.  No Subordinated Creditor, solely in its capacity as a Subordinated Creditor or Last Out Lender under the ABL Credit Agreement, shall take any action in any Insolvency Proceeding in any way so as to contest, and hereby waives any rights it may have to contest (a) the validity or enforceability of any of the ABL Loan Documents, (b) the rights and duties of the ABL Agent and the ABL Secured Parties established in any of the ABL Loan Documents or (c) the validity or enforceability of the subordination provisions set forth in this Agreement.

2.04                        Turnover by the Subordinated Creditors.  If any payment or distribution of any character (other than Exempt Last Out Loan Proceeds), whether in cash, securities or other property, in respect of this Agreement (so far as it relates to the ABL Obligations or the

5

Subordinated Indebtedness) or the ABL Loan Documents shall be received by any Subordinated Creditor in contravention of these Subordination Terms, such payment or distribution shall be held in trust for the benefit of, and shall be paid over or delivered to the ABL Agent (on behalf of the ABL Secured Parties) to the extent necessary to effect the Discharge of ABL Obligations.

2.05                        No Petition.  So long as any ABL Obligation is outstanding, any Subordinated Creditor in its capacity as such and as a Last Out Lender, in each case, shall not commence, or join with any creditor in commencing,  any Insolvency Proceeding.

2.06                        No Effect.  Unless the ABL Secured Parties and the Subordinated Creditors so expressly subsequently agree, these Subordination Terms shall not be affected by (i) any amendment or modification of, or addition or supplement to, the ABL Credit Agreement or any other ABL Loan Document, (ii) any exercise or non-exercise of any right, power or remedy under or in respect of the ABL Credit Agreement or any other ABL Loan Document, or (iii) any waiver, consent, release, extension, renewal, modification, delay, or other action, inaction or omission in respect of the ABL Credit Agreement or any other ABL Loan Document.

2.07                        Continuation.  The provisions of these Subordination Terms constitute a continuing agreement and shall (i) remain in full force and effect until the Discharge of ABL Obligations, (ii) be binding upon the Subordinated Creditors, the Obligors and the other parties hereto and their respective successors, transferees and assignees and (iii) inure to the benefit of, and be enforceable by, the ABL Agent (on behalf of the ABL Secured Parties).  These Subordination Terms and this Agreement shall automatically, and without further action, terminate and have no further force or effect as to the Borrowers upon the Discharge of ABL Obligations.

2.08                        No Impairment; Automatic Restoration.  Except to the extent otherwise expressly provided in the ABL Loan Documents, the foregoing provisions are solely for the purpose of defining the relative rights of the holders of the ABL Obligations on the one hand and the Subordinated Creditors on the other hand, and nothing herein shall impair or affect, as between the Obligors and the Subordinated Creditors, the obligations of the Obligors, which are unconditional and absolute, to pay to the Subordinated Creditors the Subordinated Indebtedness in accordance with the terms of the ABL Loan Documents.  These Subordination Terms shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of any Obligor in respect of the ABL Obligations is rescinded or must be otherwise restored by any holder of any of the ABL Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise.

Section 3.                                           Insolvency Proceedings.  Without limiting the provisions of Section 2 hereof, the Obligors hereby agree as follows:

3.01                        Finance and Sale Matters.  (a) Until the Discharge of ABL Obligations has occurred (other than a Discharge of ABL Obligations arising from the Refinancing of the ABL Obligations with the proceeds of a DIP Financing (as defined below) or otherwise), each of the Subordinated Creditors agrees that, in the event of any Insolvency Proceeding, such Subordinated Creditor:

6

(i)                                     will not take any step or action (whether directly or indirectly) in such Insolvency Proceeding to oppose, object to, impede, or delay the use of any ABL Collateral constituting cash collateral (including, without limitation, any and all terms of any cash collateral order) under Section 363 of the Bankruptcy Code, or any comparable provision of any other Bankruptcy Law, unless the ABL Secured Parties, or a representative authorized by the requisite ABL Secured Parties, shall oppose or object to such use of cash collateral;

(ii)                                  will not take any step or action (whether directly or indirectly) in such Insolvency Proceeding to oppose, object to, impede, or delay any post-petition equity or debt financing (including, without limitation, any and all terms of any financing agreement, related documents and financing order), whether provided by Secured Parties or any other person, under Section 364 of the Bankruptcy Code, or any comparable provision of any other Bankruptcy Law (a “DIP Financing”), or the Liens securing any DIP Financing (“DIP Financing Liens”), or any grant of adequate protection in connection with any DIP Financing, unless in each case the ABL Secured Parties, or a representative authorized by the requisite ABL Secured Parties, shall then oppose or object to such DIP Financing or such DIP Financing Liens;

(iii)                               in connection with the use of cash collateral as described in clause (i) above or a DIP Financing, will not request adequate protection (except as otherwise provided under Section 3.04(b) hereof) or any other relief in connection with such use of cash collateral, DIP Financing or DIP Financing Liens; and

(iv)                              will not take any step or action (whether directly or indirectly) in such Insolvency Proceeding to oppose, object to, impede, or delay any sale or other disposition of any assets (including, without limitation, the terms and conditions of any bidding procedures orders, sale orders and any and all purchase and sale agreements and related documents) free and clear of Liens under the ABL Security Documents or other claims, whether under Section 363 of the Bankruptcy Code (or any comparable provision of any other Bankruptcy Law) or otherwise, if the ABL Secured Parties, or a representative authorized by the requisite ABL Secured Parties, shall consent to such Disposition.

(b)                                 Each of the Subordinated Creditors agrees that it shall not oppose, contest or challenge, or support any other person in opposing, contesting or challenging, (i) any request by the ABL Agent or any other ABL Secured Party for adequate protection in any form or (ii) any objection, based on a claim of a lack of adequate protection, by the ABL Agent or any other ABL Secured Party to any motion, relief, action or proceeding.

(c)                                  Each of the Subordinated Creditors hereby expressly and irrevocably waives, for the benefit of ABL Agent and ABL Secured Parties any principles or provisions of law (including as set forth in any Bankruptcy Law, statutory or otherwise) which are or might be in conflict with the terms of this Agreement and any legal or equitable discharge of such Subordinated Creditor’s obligations hereunder.

3.02                        Relief from the Automatic Stay.  Notwithstanding anything to the contrary contained herein, each of the Subordinated Creditors agrees that, so long as the Discharge of

7

ABL Obligations has not occurred, it shall not, without the prior written consent of the ABL Agent, seek or request relief from or modification of the automatic stay or any other stay in any Insolvency Proceeding in respect of any part of the ABL Collateral or any proceeds thereof.

3.03                        Reorganization Securities.  Without prejudice to Section 2 hereof, if, in any Insolvency Proceeding, debt obligations of the reorganized debtor secured by Liens upon any property of the reorganized debtor are distributed, pursuant to a plan of reorganization or similar dispositive restructuring plan, on account of both the ABL Obligations and the Subordinated Obligations, then, to the extent the debt obligations distributed on account of the ABL Obligations and on account of the Subordinated Obligations are secured by Liens upon the same assets or property, the provisions of this Agreement will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations.

3.04                        Post-Petition Interest; Adequate Protection.  (a) Each of the Subordinated Creditors agrees that it shall not oppose or seek to challenge any claim by the ABL Agent or any other ABL Secured Party for allowance of ABL Obligations consisting of principal, post-petition interest at the default rate, fees, expenses, or any other ABL Obligations, or payment of such claims, in any Insolvency Proceeding.

(b)                                 If any of the Subordinated Creditors obtains any adequate protection payment in respect of the Subordinated Indebtedness in any Insolvency Proceeding, then it agrees to turnover such payment to the ABL Agent (on behalf of the ABL Secured Parties other than the Subordinated Creditors); provided, that if the ABL Secured Parties receive as adequate protection of their interests in the ABL Collateral, (i) a replacement Lien in the ABL Collateral or (ii) superpriority claims, the Subordinated Creditors may, as adequate protection of their interests in the ABL Collateral, receive adequate protection consisting solely of (x) such replacement Lien on the ABL Collateral with respect to the Last Out Loans otherwise subject to the terms of this Agreement, including this Section 3.04(b) with respect to any proceeds of such Lien, and (y) superpriority claims junior in all respects to the superpriority claims granted to the ABL Secured Parties; provided, however, that each Subordinated Creditor shall have irrevocably agreed, pursuant to Section 1129(a)(9) of the Bankruptcy Code, in any stipulation and/or order granting such adequate protection, that such junior superpriority claims may be paid under any plan of reorganization in any combination of cash, debt, equity or other property having a value on the effective date of such plan equal to the allowed amount of such claims;

3.05                        Certain Waivers by the Subordinated Creditors.  Each Subordinated Creditor waives any claim it may hereafter have against any ABL Secured Party arising out of (a) the election by any ABL Secured Party of the application of Section 1111(b)(2) of the Bankruptcy Code, or any comparable provision of any other Bankruptcy Law, or (b) any cash collateral or financing arrangement, or any grant of a security interest in the ABL Collateral, in any Insolvency Proceeding.

3.06                        Filing of Motions.  Until the Discharge of ABL Obligations has occurred, each of the Subordinated Creditors agrees that it shall not, in or in connection with any Insolvency Proceeding, file any pleadings or motions, take any position at any hearing or proceeding of any nature, or otherwise take any action whatsoever, in each case in respect of any

8

of the ABL Collateral, including without limitation with respect to the determination of any Liens or claims held by the ABL Agent (including the validity and enforceability thereof) or any other ABL Secured Party or the value of any claims of such parties under Section 506(a) of the Bankruptcy Code or otherwise.

3.07                        Separate Grants of Security and Separate Classification.  (a) Each of the Subordinated Creditors and the ABL Agent (on behalf of the ABL Secured Parties) acknowledges and agrees that (to the extent applicable) because of, among other things, their differing rights in the ABL Collateral, the Subordinated Indebtedness is not similarly situated to the ABL Obligations and must be separately classified in any plan of reorganization proposed or adopted in any Insolvency Proceeding.

(b)                                 To further effectuate the intent of the parties as provided in paragraph (a), if it is held (i) that the claims of the ABL Secured Parties and the Subordinated Creditors in respect of the ABL Collateral constitute only one secured claim (rather than separate classes of senior and junior secured claims), then each of the Subordinated Creditors and the ABL Agent (on behalf of the ABL Secured Parties) hereby acknowledge and agree that all distributions shall be made as if there were separate classes of senior and junior secured claims against the Obligors in respect of the ABL Collateral (with the effect being that, to the extent that the aggregate value of the ABL Collateral is sufficient (for this purpose ignoring all claims held by the Subordinated Creditors), the ABL Secured Parties shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of post-petition interest at the default rate before any distribution is made in respect of the claims held by the Subordinated Creditors), with each of the Subordinated Creditors hereby acknowledging and agreeing to turn over to the ABL Agent, for distribution to the ABL Secured Parties, amounts otherwise received or receivable by them to the extent necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Subordinated Creditors.

3.08                        Plans of Reorganization.  ABL Agent is hereby irrevocably authorized and empowered (in the name of each Subordinated Creditor) to vote on behalf of such Subordinated Creditor or consent or object on behalf of such Subordinated Creditor in any Insolvency Proceeding with respect to any and all claims of such Subordinated Creditors relating to the Subordinated Indebtedness, and each of the Subordinated Creditors hereby appoints the ABL Agent as its agent, and grants to the ABL Agent an irrevocable power of attorney coupled with an interest, and its proxy, for the purpose of exercising any and all rights and taking any and all actions available to such Subordinated Creditor in connection with any case by or against the Obligors in any Insolvency Proceeding, including without limitation, the right to file and/or prosecute any claims, to support or vote in favor of any plan of reorganization, or to make any election under Section 1111(b) of the Bankruptcy Code.  Each of the Subordinated Creditors agrees and that such Subordinated Creditor shall be irrevocably bound to any such votes made or consents given and further shall not challenge or otherwise object to such votes or consents and shall not itself vote or provide consents in the proceeding  To the extent that any Subordinated Creditor attempts to vote or votes in favor of any plan or reorganization in a manner inconsistent with this Section 3.08, each of the Subordinated Creditors irrevocably agrees that the ABL Agent may be, and may be deemed, an “authorized agent” of such party under Bankruptcy Rules

9

3018(c) and 9010, and that the ABL Agent shall be authorized and entitled to submit a superseding ballot on behalf of such Subordinated Creditor that is consistent herewith.

3.09                        Other Matters.  Each of the Subordinated Creditors agrees not to assert any rights under Section 363 or Section 364 of the Bankruptcy Code with respect to any of the ABL Collateral without the prior written consent of the ABL Agent; provided that if requested by the ABL Agent, such Subordinated Creditor shall timely exercise such rights in the manner requested by the ABL Agent, as applicable, including any rights to payments in respect of such rights.

3.10                        Effectiveness in Insolvency Proceedings.  This Agreement, which the parties hereto expressly acknowledge is a “subordination agreement” under section 510(a) of the Bankruptcy Code, shall be effective before and after the commencement of an Insolvency Proceeding.  All references in this Agreement to any Obligor shall include such Obligor as a debtor-in-possession and any receiver or trustee for such Obligor in any Insolvency Proceeding.

3.11                        Intercreditor Agreement.  Each of the Secured Parties and the Obligors acknowledge and agree that nothing in this Section 3 or elsewhere in this Agreement shall impair or otherwise affect the respective rights and obligations under the Intercreditor Agreement of (a) any Secured Party, in its capacity as the ABL Representative (as defined therein) or an ABL Secured Party (as defined therein), (b) any Subordinated Creditor, in its capacity as the Term Debt Representative (used in this Section as defined in the Intercreditor Agreement) or a Term Debt Secured Party (used in this Section as defined in the Intercreditor Agreement) or in any capacity other than as a Subordinated Creditor or (c) any Obligor; provided, however, that no Person that is a Subordinated Creditor, but acting or purporting to act in its capacity as Term Debt Representative or a Term Debt Secured Party, shall take any action or exercise its rights, remedies and powers under the Intercreditor Agreement or otherwise to the extent such action or exercise would advantage or benefit such Person principally in its capacity as a Subordinated Creditor against the ABL Agent or ABL Secured Parties (in their respective capacities as such).
