No delay or failure of Lender to demand strict adherence to the terms of this Agreement or the Related Documents shall be deemed to constitute a course of conduct inconsistent with Lender's right at any time, before or after any Event of Default, to prospectively demand strict adherence to the terms of this Agreement and the Related Documents. 7. SUBORDINATION. A. The indebtedness evidenced by the Second Amended Note and any renewals or extensions thereof (such indebtedness being herein called the "Subordinated Indebtedness") shall at all times be wholly subordinate and junior in right to payment in full of all Senior Debt (as defined below). The provisions of this section on subordination shall constitute a continuing offer to all persons who, in reliance upon such provisions, become holders of, or continue to hold, Senior Debt, and such provisions are made for the benefit of the holders of Senior Debt, and such holders are hereby made obligees hereunder the same as if their names were written herein as such, and they and/or each of them may proceed to enforce such provisions. Unless and until an event of default under any of the Senior Debt (other than an event of default which exists solely by reason of a default under this Agreement) shall have occurred and be continuing ("Superior Default"), Borrowers shall pay the principal and interest on all Subordinated Indebtedness according to the terms hereof. For purposes of this Agreement, "Senior Debt" means the principal of, and interest on and other amounts due on or in connection with any Indebtedness of Borrowers (other than the Second Amended Note) to any Financial Institution (as defined below), whether outstanding on the date of this Agreement, or thereafter created, incurred or assumed by Borrowers (including all deferrals, renewals, extensions or refundings of, or amendments, modifications or supplements to, Indebtedness of the kind described in this clause). Notwithstanding anything herein to the contrary, Senior Debt shall not include: (a) Indebtedness of or amounts owed by Borrowers for compensation to employees, or for goods or materials purchased in the ordinary course of business or for services, or (b) Indebtedness either Borrower to its subsidiary or affiliate. In no event shall any Financial Institution be deemed to be an affiliate of Borrowers. Indebtedness of either Borrower to its subsidiary or affiliate shall be pari passu in all respects with the Subordinated Indebtedness. For purposes of this Agreement, "Financial Institution" means any bank as defined in section 3(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), savings and loan association or other institution as defined in section 3(a)(5)(A) of the Securities Act, insurance company as defined in section 2(13) of the Securities Act, or investment banking firm. -4- For purposes of this Agreement, "Indebtedness" means, with respect to any person, (a) any liability, contingent or otherwise, of such person (i) for borrowed money (whether or not the recourse of the lender is to the whole of the assets of such person or only to a portion thereof), (ii) evidenced by a note, debenture or similar instrument or representing the balance deferred and unpaid of the purchase price of any property purchased, or (iii) for the payment of money relating to a lease that is required to be capitalized under generally accepted accounting principles; (b) any obligation secured by a lien to which the property or assets of such person are subject, whether or not the obligations secured thereby shall have been assumed by or shall otherwise be such person's legal liability; and (c) any and all deferrals, renewals, extensions and refundings of, or amendments, modifications or supplements to, any liability of the kind described in any of the preceding clauses (a) or (b). B. The terms hereof, the subordination effected hereby and the rights of the holders of the Senior Debt shall not be affected by (a) any amendment of or addition or supplement to any Senior Debt or any instrument or agreement relating thereto, (b) any exercise or non-exercise of any right, power or remedy under or in respect of any Senior Debt or any instrument or agreement relating thereto, or (c) any waiver, consent, release, indulgence, extension, renewal, modification, delay or other action, inaction or omission, in respect of any Senior Debt or any instrument or agreement relating thereto or any security therefor or guaranty thereof, whether or not any holder of any Subordinated Indebtedness shall have had notice or knowledge of any of the foregoing. C. Upon the happening of (a) a Superior Default which is a default in respect of payment of principal, premium, if any, or interest on Senior Debt or (b) a Superior Default (other than a Superior Default in respect of payment of principal, premium, if any, or interest on Senior Debt) and receipt by Lender of written notice thereof from any holder of Senior Debt, then until all Senior Debt shall have been paid in full, Borrowers shall not, directly or indirectly, make or agree to make, and neither Lender nor any assignee or successor holder of any Subordinated Indebtedness shall demand, accept or receive (a) any payment (in cash, property or securities, by set-off or otherwise), direct or indirect, of or on account of any principal or interest in respect of any Subordinated Indebtedness, and no such payment shall be accepted by any holder of any Subordinated Indebtedness, or (b) any payment for the purpose of any redemption, purchase or other acquisition, direct or indirect, of any Subordinated Indebtedness, and no such payment shall be due. In the case of any Superior Default (other than a Superior Default with respect to payment of principal, premium, if any, or interest on Senior Debt), the foregoing restrictions shall cease to apply to any payment received with respect to the Subordinated Indebtedness after the expiration of 180 days after the holder of the Second Amended Note shall have received notice of the Superior Default, unless prior to the expiration of such 180-day period one or more holders of the Senior Debt shall have commenced and be diligently prosecuting an action, suit or other legal or equitable proceeding against Borrower or its property based upon the Superior Default or unless a Superior Default which is a payment default shall have occurred and be continuing; provided, further, that during such 180-day period following the Superior Default (other than a Superior Default with respect to payment of principal, premium, if any, or interest on Senior Debt) the holders of the Subordinated Indebtedness shall refrain from prosecuting any such action, suit or other legal or equitable proceeding against either Borrower or its property based upon an Event of Default hereunder. In the event that a Superior Default (other than a Superior Default with respect to payment of principal, premium or interest on Senior Debt) is cured or is waived by the appropriate holders of the Senior Debt (whether by amendment to the applicable loan -5- agreement, forbearance agreement or otherwise) prior to the expiration of the aforesaid 180-day period applicable to such Superior Default, then any Event of Default occurring under this Agreement solely by reason of the occurrence of such Superior Default shall be deemed not to have occurred. Any judicial proceedings initiated by a holder of Subordinated Indebtedness at a time when such holder has no knowledge that such proceedings are prohibited by this paragraph shall not be deemed a violation of any provisions of this Agreement and, upon receipt of notice from the holder of the Senior Debt that such proceedings are so prohibited, such holder of the Subordinated Indebtedness shall terminate such proceedings, without prejudice. D. Upon any distribution (whether of cash, securities or other property) to creditors of either Borrower in a liquidation or dissolution of such Borrower, or in a bankruptcy, reorganization, insolvency, receivership, assignment for the benefit of creditors, marshalling of assets or similar proceeding relating to such Borrower or its property: (1) holders of Senior Debt shall be entitled to receive payment in full in cash of such Senior Debt (including interest accruing after the commencement of any such proceeding or interest that would have accrued but for the commencement of such proceeding to the date of payment on, and other amounts included in, Senior Debt) before the holder of the Second Amended Note shall be entitled to receive any payment of principal of, premium (if any) or interest on the Second Amended Note or any other distributions with respect to the Second Amended Note; (2) until the Senior Debt is paid in full in cash as provided in clause (1) of this paragraph, any distribution to which the holder of the Second Amended Note would be entitled but for this section on subordination shall be made to the holders of Senior Debt as their interests may appear. In the event that any payment or distribution of assets of either Borrower prohibited by the provisions of this section on subordination of any kind or character, whether in cash, property or securities, shall be received by the holder of the Second Amended Note before all Senior Debt is paid in full, or provision made for such payment in accordance with the terms of the Senior Debt, such payment or distribution shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of such Senior Debt or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any of such Senior Debt may have been issued, as their respective interests may appear, for application to the payment of all Senior Debt remaining unpaid to the extent necessary to pay such Senior Debt in full in accordance with its terms, after giving effect to any concurrent payment or distribution to the holders of such Senior Debt. E. In the event that the Second Amended Note is declared due and payable before its stated maturity because of the occurrence of an Event of Default hereunder, the holders of the Senior Debt shall be entitled to receive payment in full of all amounts due with respect to all Senior Debt before the holder of the Second Amended Note is entitled to receive any payment on account of the principal of, premium (if any) or interest on, or any repurchase, redemption or other retirement (including, without limitation, any defeasance) of, the Second Amended Note. F. Subject to the payment in full of all Senior Debt, the holders of Subordinated Indebtedness shall be subrogated to the rights of the holders of Senior Debt to receive payments or distributions of assets of Borrowers applicable to the Senior Debt until all amounts owing on the Subordinated Indebtedness shall be paid in full, and for the purpose of such subrogation no such payments or distributions to the holders of -6- Senior Debt by or on behalf of Borrowers by virtue of this Agreement which otherwise would have been made to the holder of the Second Amended Note, shall, as between Borrowers and the holder of the Second Amended Note, be deemed to be payment by Borrowers to or on account of the Senior Debt, it being understood that the provisions of this paragraph are intended solely for the purpose of defining the relative rights of the holders of Subordinated Indebtedness on the one hand and the holders of Senior Debt, on the other hand. Nothing contained herein is intended to or shall impair, as between Borrowers and Lender, the obligation of Borrowers, which is absolute and unconditional, to pay to Lender, the principal of and interest on the Subordinated Indebtedness as and when the same shall become due and payable in accordance with its terms, or is intended to or shall affect (except to the extent specifically provided in the above paragraph) the relative rights of the holders hereof and creditors of Borrowers other than the holders of the Senior Debt, nor shall anything herein or therein prevent any holder of the Second Amended Note from exercising all remedies otherwise permitted by applicable law upon default hereunder subject to the rights, if any, hereunder of the holders of Senior Debt in respect of cash, property or securities of Borrower received upon the exercise of any such remedy. 8.
