The Company covenants and agrees, and Junior Creditor likewise covenants and agrees, that the payment of any and all of the Junior Debt shall be subordinate and subject in right of payment, to the extent and in the manner hereinafter set forth, to the prior payment in full in cash of the Senior Debt, and that the holder of Senior Debt, whether now outstanding or hereafter created, incurred, assumed or guaranteed, shall be deemed to have consented to the Junior Debt and the Junior Security Agreement in reliance upon the provisions contained in this Agreement.

2.2 Proceedings. In the event of any Proceeding involving the Company, (a) all Senior Debt first shall be paid in full in cash before any payment of or with respect to the Junior Debt shall be made; (b) any payment or distribution, whether in cash, property or securities which, but

for the terms hereof, otherwise would be payable or deliverable in respect of the Junior Debt, shall be paid or delivered directly to Senior Creditor (to be held and/or applied by Senior Creditor in accordance with the terms of the Senior Security Agreement) until all Senior Debt is paid in full in cash, and Junior Creditor irrevocably authorizes, empowers and directs all receivers, trustees, liquidators, custodians, conservators and others having authority in the premises to effect all such payments and distributions, and Junior Creditor also irrevocably authorizes, empowers and directs Senior Creditor to demand, sue for, collect and receive every such payment or distribution; (c) Junior Creditor agrees to execute and deliver to Senior Creditor or its representative all such further instruments confirming the authorization referred to in the foregoing clause (b), (d) Junior Creditor agrees not to initiate or prosecute or encourage any other person to initiate or prosecute any claim, action or other proceeding challenging the enforceability of the Senior Debt or any liens and security interests securing the Senior Debt, and (e) Junior Creditor agrees to execute, verify, deliver and file any proofs of claim in respect of the Junior Debt requested by Senior Creditor in connection with any such Proceeding and hereby irrevocably authorizes, empowers and appoints Senior Creditor its agent and attorney-in-fact to (i) execute, verify, deliver and file such proofs of claim upon the failure of Junior Creditor promptly to do so (and, in any event, prior to 30 days before the expiration of the time to file any such proof) and (ii) vote such claim in any such Proceeding upon the failure of Junior Creditor to do so prior to 15 days before the expiration of the time to vote any such claim; provided Senior Creditor shall have no obligation to execute, verify, deliver, file and/or vote any such proof of claim.

2.5 Incorrect Payments. If any payment or distribution on account of the Junior Debt not permitted to be made by the Company or its subsidiaries or received by Junior Creditor under this Agreement is received by Junior Creditor before all Senior Debt is paid in full in cash, such payment or distribution shall not be commingled with any asset of Junior Creditor, shall be held in trust by Junior Creditor for the benefit of Senior Creditor and shall be promptly paid over to Senior Creditor, or its designated representative, for application (in accordance with the Senior Security Agreement) to the payment of the Senior Debt then remaining unpaid, until all of the Senior Debt is paid in full in cash.

2.6 Sale, Transfer, etc; Security. Junior Creditor shall not sell, assign, pledge, dispose of or otherwise transfer all or any portion of the Junior Debt, unless the transferee thereof agrees to be bound by this Agreement.
