Subordination. ------------- (a) Each of the Obligors and the Junior Creditors hereby covenants and agrees that the Subordinated Indebtedness, howsoever evidenced and whether now existing or hereafter incurred, shall be subordinate and junior in right of payment, to the extent and in the manner hereinafter set forth, to the prior payment in full of all Senior Indebtedness. Notwithstanding anything to the contrary contained in the Junior Credit Agreement, any Junior Guaranty or otherwise, it is agreed by the parties hereto that (i) the Subordinated Indebtedness shall not be payable, and no Obligor shall make any payment (whether of principal, accrued interest or otherwise) or other distribution of, on or with respect to any Subordinated Indebtedness, and no Junior Creditor shall receive, accept, retain or apply any such payment or other distribution, unless and until all Senior Indebtedness shall have been Indefeasibly Paid in full and (ii) no property or Collateral Security or guarantee of any nature to secure, guarantee or pay the Subordinated Indebtedness shall be made or given, directly or indirectly, by any Obligor, or shall be received, accepted, retained or applied by any Junior Creditor (and no right or remedy of any Junior Creditor with respect to any of the foregoing may be exercised) unless and until all Senior Indebtedness shall have been Indefeasibly Paid in full; provided, -------- however, that this Agreement shall not prohibit (A) the execution and delivery - ------- of the Junior Guaranties (as opposed to payments made thereunder), or (B) the execution and delivery of any guaranty issued by a Subsidiary of the Borrower which is created in the future (as opposed to payments thereunder) if (but only if) such guaranty is a Junior Guaranty and is subordinated to the Senior Indebtedness in the same manner as are the Junior Guaranties in accordance with this Agreement and each such Subsidiary executes this Agreement as an "Obligor" or executes a joinder agreement in a form and substance satisfactory to the Senior Agent which effectively makes such Subsidiary a party to this Agreement as an "Obligor". (For purposes of this Paragraph 2(a), neither the preferred ------------- stock issued by Holdings nor dividends paid in kind by Holdings with respect to such preferred stock in the form of additional preferred stock of the same class, in each case as referred to in clause (i) of the definition of the term --------- "Subordinated Indebtedness", nor the payment of interest in kind in the form of principal of additional Subordinated Indebtedness of the same class referred to in clause (ii) of the definition of the term "Subordinated Indebtedness", shall ---------- be deemed to constitute any payment or other distribution of, on or with respect to any Subordinated Indebtedness.) In addition, each Junior Creditor hereby waives, and agrees not to exercise, any and all rights of setoff that it may now or hereafter have against the property or assets of any Obligor unless and until all of the Senior Indebtedness shall have been Indefeasibly Paid in full. SUBORDINATION AGREEMENT - Page 4 (b) Each of the Junior Creditors hereby agrees that (i) in the event any Obligor offers to any Junior Creditor any payment (including any payment received as proceeds of any Collateral Security for the Subordinated Indebtedness) or any other distribution of any property on account of any Subordinated Indebtedness which payment or other distribution is not permitted hereby (collectively, "Prohibited Payments"), such Junior Creditor will direct ------------------- that the full amount of the Prohibited Payment be made or delivered directly to the Senior Agent for the benefit of the Senior Creditors; (ii) any Prohibited Payment or other payment or distribution received by any Junior Creditor in violation of this Agreement from any source whatsoever will be promptly delivered to the Senior Agent in the form received (except for endorsements or assignments by such Junior Creditor where appropriate or required by the Senior Creditors) and until so delivered to the Senior Agent will be held by the Junior Creditor receiving such Prohibited Payment or other payment or distribution in trust as the Senior Creditors' property; and (iii) the Senior Creditors shall retain all moneys collected or received pursuant to the exercise of the foregoing powers and shall apply said moneys to the payment of Senior Indebtedness then outstanding (whether matured or unmatured), provided that after satisfying all amounts owing, or to be owed, to the Senior Creditors with respect to the matured and unmatured Senior Indebtedness, including the payment of all related costs and expenses incurred by the Senior Creditors, the Senior Creditors shall pay the excess, if any, to the Junior Agent on account of the Subordinated Indebtedness and subrogate their rights, if any, in such excess to the Junior Creditors. The Junior Creditors agree that no payment or distribution to the Senior Creditors pursuant to the provisions of this Agreement shall entitle any Junior Creditor to exercise any rights of subrogation in respect thereof until the Senior Indebtedness shall have been Indefeasibly Paid in full. 3. Bankruptcy or Related Proceedings. Upon any distribution of any --------------------------------- property or assets of any Obligor upon any dissolution, winding up, liquidation or reorganization of such Obligor, whether in bankruptcy, insolvency, reorganization or receivership proceedings or upon any assignment for the benefit of creditors or any marshalling of assets or liabilities of such Obligor or otherwise: (a) the Senior Indebtedness shall have been Indefeasibly Paid in full, and the Senior Agent, for the benefit of the Senior Creditors, shall be entitled to receive such payment in full of all Senior Indebtedness, or provision satisfactory to the Senior Agent in its sole and absolute discretion shall be made for payment thereof in full in cash, before any Junior Creditor is entitled to receive any payment or other distribution on account of or with respect to any Subordinated Indebtedness; (b) any payment by, or any distribution of assets or properties of, any Obligor of any kind or character, whether in cash, property or securities, to which any Junior Creditor would be entitled except for the terms and provisions of this Agreement shall be paid or delivered by the Person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the Senior Agent (for the benefit of the Senior Creditors) to the extent necessary to make the Senior Indebtedness Indefeasibly Paid in full after giving effect to any concurrent payment or distribution (or provision therefor satisfactory to the Senior Agent) to the Senior Agent (for the benefit of the Senior Creditors); (c) in the event that, notwithstanding the foregoing, any payment by, or distribution of assets or properties of, any Obligor of any kind or character, whether in cash, property or securities, shall be directly or indirectly received by any Junior Creditor before all Senior Indebtedness shall SUBORDINATION AGREEMENT - Page 5 be Indefeasibly Paid in full (whether or not the Senior Indebtedness is then due or payable), such payment or distribution will be promptly delivered to the Senior Agent in the form received (except for endorsements or assignments by such Junior Creditor where appropriate or required by the Senior Creditors) for application to payment of the Senior Indebtedness remaining unpaid after giving effect to any current payment or distribution to the Senior Agent (for the benefit of the Senior Creditors) and until so delivered to the Senior Agent will be held by such Junior Creditor in trust as the Senior Creditors' property; and (d) for purposes of this Paragraph 3, neither the preferred stock ----------- issued by Holdings nor dividends paid in kind by Holdings with respect to such preferred stock in the form of additional preferred stock of the same class, in each case as referred to in clause (i) of the definition of the term --------- "Subordinated Indebtedness", nor the payment of interest in kind in the form of principal of additional Subordinated Indebtedness of the same class referred to in clause (ii) of the definition of the term "Subordinated Indebtedness", shall ---------- be deemed to constitute any payment or other distribution of, on or with respect to any Subordinated Indebtedness. 4. No Actions against Obligors. Each of the Junior Creditors agrees --------------------------- that it shall not, unless and until all Senior Indebtedness has been Indefeasibly Paid in full, commence or join in any action against any Obligor relating to the Subordinated Indebtedness. In the event any Obligor or its assets or properties become subject to any bankruptcy, insolvency, reorganization, moratorium or similar laws generally affecting creditors' rights, the Junior Creditors will file any claim, proof of claim or other document of similar character necessary to enforce the Subordinated Indebtedness against the Obligors. In the event that, notwithstanding the foregoing, any Junior Creditor fails to file any such claim, proof of claim or other document of similar character, such Junior Creditor authorizes the Senior Agent to file such claim, proof of claim or other document of similar character on behalf of such Junior Creditor. 5. Subordination of Collateral Security. Each of the Obligors and the ------------------------------------ Junior Creditors represents and warrants that the Subordinated Indebtedness is unsecured; however, if and to the extent that the Subordinated Indebtedness becomes secured, each of the Junior Creditors agrees that whatever right, title or interest (including security interest) it may have at any time in or to any Collateral Security for the Subordinated Indebtedness shall, at all times and in all respects, be subject and subordinate in all respects to any right, title or interest (including security interest) of the Senior Agent (for and on behalf of the Senior Creditors) in or to any such Collateral Security, irrespective of the time or order of the creation or perfection of any such right, title or interest (including security interest) and irrespective of any failure by the Senior Agent to create or perfect any such right, title or interest (including security interest). 6. Restriction on Transfer of Subordinated Indebtedness. Each of the ---------------------------------------------------- Junior Creditors agrees not to (a) assign or transfer all or any part of the Subordinated Indebtedness or any claim which such Junior Creditor may have against any Obligor except pursuant to an agreement which is expressly made subject to all terms and provisions of this Agreement, or (b) to subordinate all or any part of the Subordinated Indebtedness or any claim which such Junior Creditor may have against any Obligor except pursuant to this Agreement or any subsequent agreement acceptable to the Senior Creditors. SUBORDINATION AGREEMENT - Page 6 7. Power of Attorney. The Senior Agent and each of its officers is ----------------- hereby irrevocably constituted and appointed the attorney-in-fact for each of the Junior Creditors with full power and authority to do the following, in each case only to the extent necessary or appropriate to carry out and/or enforce this Agreement: (a) to make endorsements and assignments with full power of substitution in the event any Junior Creditor does not make any endorsements or assignments referred to herein, (b) subject to Paragraph 4 hereof, to demand, ----------- sue for or to file proofs of debt or claim with respect to Subordinated Indebtedness, (c) to enforce the Junior Creditors' rights generally, and (d) to take all such other actions as the Senior Agent may deem necessary or appropriate to carry out and/or enforce this Agreement and/or to exercise the rights of the Senior Creditors, or any one or more of them, hereunder. The Senior Agent shall not be obligated to exercise any authority or right granted to it hereunder, and shall not be liable for any action taken or omitted or the manner of taking any action except for actions which are determined by a court of competent jurisdiction in a non-appealable case to constitute the gross negligence or willful misconduct of the Senior Agent, as to which gross negligence or willful misconduct the Senior Agent shall be liable only for any actual damages proven and shall not be liable for any consequential, exemplary or punitive damages. 8. Books and Records. Each of the Obligors and the Junior Creditors ----------------- agrees (a) to make proper notations in its respective books, records or other statements which evidence or record any Subordinated Indebtedness ("Records") ------- indicating that the Subordinated Indebtedness is subject to the provisions of this Agreement, (b) to give the Senior Agent and its representatives access at any time and from time to time during normal business hours and upon reasonable prior notice, upon the request of any Senior Creditor (which request made of a Junior Creditor other than the Junior Agent must be reasonable), to its respective Records in order to make a full and free examination of and to copy the Records, (c) to furnish the Senior Agent at any time and from time to time, upon the reasonable request of the Senior Agent, with statements of account relating to the Subordinated Indebtedness and (d) to place a legend on any promissory note or other instrument evidencing the Subordinated Indebtedness to reflect that the indebtedness represented thereby is subordinated pursuant to the terms of this Agreement. 9. Future Subordinated Indebtedness. In the event any Obligor shall -------------------------------- at any time hereafter become otherwise indebted to any of the Junior Creditors, contingently or otherwise, each of the Junior Creditors agrees that it will require such indebtedness to be evidenced by an instrument or document signed by such Obligor which complies with the provisions of Paragraph 8 hereof. Unless ----------- and until the Senior Indebtedness is Indefeasibly Paid in full, each of the Junior Creditors agrees that it will promptly notify the Senior Agent in writing if such Junior Creditor receives any payment on account of or any Collateral Security or guarantee for any Subordinated Indebtedness at a time when no Senior Indebtedness is outstanding; provided, however, that the Senior Agent shall use -------- ------- reasonable efforts to notify the Junior Agent when the Senior Indebtedness is Indefeasibly Paid in full; provided, further, however, that the Senior Agent's -------- ------- ------- failure to do so shall not affect the obligations of the Junior Creditors hereunder or result in any liability to the Senior Agent. Subject to Paragraph --------- 22 hereof, in the event that such Junior Creditor fails to notify the Senior - -- Agent as provided in the preceding sentence and any new Senior Indebtedness is thereafter created and any Obligor thereafter defaults with respect to the payment or performance of its indebtedness, liabilities or obligations with respect to any Senior Indebtedness, then, in addition to and not in limitation of any other rights or remedies available to the Senior Creditors, the Senior Creditors shall have the right to receive, and such Junior Creditor will promptly pay to the Senior Agent, an amount SUBORDINATION AGREEMENT - Page 7 equivalent to any payment or the value of any Collateral Security received by such Junior Creditor and not reported to the Senior Agent. 10. Rights Concerning Senior Indebtedness. Without affecting the ------------------------------------- rights of the Senior Creditors hereunder, each of the Junior Creditors agrees that, with or without notice to or further assent from the Junior Creditors, the Senior Creditors may at any time, and from time to time, either prior to or after any default by any Obligor with respect to any indebtedness, (a) advance or refuse to advance additional credit and make other accommodations to or for the account of any Obligor, (b) by written agreement or otherwise, extend, renew, increase or change, modify, compromise, release, refuse to extend, renew or change the Senior Indebtedness or any part thereof and waive any default under all or any part thereof, and modify, rescind or waive any provision of any related agreement or collateral undertaking, including, but not by way of limitation, any provision relating to acceleration of maturity, (c) fail to set off any or all accrued balances or deposit balances or any part thereof on the Senior Creditors' books in favor of any Obligor and/or release the same, (d) sell, surrender, release, exchange, resort to, realize upon or apply, or fail to do any of the foregoing, with respect to any Collateral Security or any part thereof held by the Senior Creditors or available to any Senior Creditor for the Senior Indebtedness, and (e) generally deal with the Obligors in such manner as the Senior Creditors may see fit, including, without limiting the generality of the foregoing, any forbearance, failure, delay or refusal by any Senior Creditor to exercise any rights or remedies any Senior Creditor may have against the Obligors, all without impairing or affecting the Senior Creditors' rights and remedies under this Agreement.
