of the Subordinated Loan Documents, that the payment of any and all of the Subordinated Debt shall be subordinate and subject in right and time of payment, to the extent and in the manner hereinafter set forth, to the prior payment in full in cash of all Senior Debt and termination of all lending commitments under the Senior Loan Documents.

Section 2.2 Subordination in a Proceeding. In the event of any Proceeding:

(a) All Senior Debt shall first be paid in full in cash and all commitments to lend under the Senior Loan Documents shall be terminated before any Distribution, whether in cash, securities or other property, shall be made to the Subordinated Creditor on account of any Subordinated Debt.

(b) Any Distribution, whether in cash, securities or other property which would otherwise, but for the terms hereof, be payable or deliverable in respect of the Subordinated Debt shall be paid or delivered directly to the Senior Creditor Representative (to be held and/or applied by the Senior Creditor Representative in accordance with the terms of the Senior Loan Documents) until all Senior Debt is paid in full in cash and all commitments to lend under the Senior Loan Documents shall have been terminated.  The Subordinated Creditor irrevocably authorizes, empowers and directs any debtor, debtor in possession, receiver, trustee, liquidator, custodian, conservator or other Person having authority, to pay or otherwise deliver all such Distributions to the Senior Creditor Representative.

(d) The Senior Debt shall continue to be treated as Senior Debt and the provisions of this Agreement shall continue to govern the relative rights and priorities of Senior Creditors and the Subordinated Creditor even if all or part of the Senior Debt or the security interests, if any, securing the Senior Debt are subordinated, set aside, avoided, invalidated or disallowed in connection with such Proceeding or otherwise, and this Agreement shall be reinstated if at any time any payment of any of the Senior Debt is rescinded or must otherwise be returned by any holder of Senior Debt or any representative of such holder.

Section 2.3 Subordinated Debt Payment Restrictions.

(a) In the event that a Senior Default has occurred and is continuing (and has not been waived in accordance with the terms of the Senior Credit Agreement) then, notwithstanding the terms of the Subordinated Loan Documents, the Borrower hereby agrees that it shall not make, whether directly or indirectly, and the Subordinated Creditor hereby agrees that it will not accept, take or claim from the Borrower, any Distribution with respect to the Subordinated Debt until the Senior Debt is paid in full in cash and all commitments to lend under the Senior Loan Documents have terminated.

(b) Notwithstanding any provision of this Section 2.3 to the contrary, the failure of the Borrower to make any Distribution with respect to the Subordinated Debt by reason of the operation of this Section 2.3 shall not be construed as preventing the occurrence of a Subordinated Default under the applicable Subordinated Loan Documents.

Notwithstanding the foregoing, any Distributions or other proceeds of any Enforcement Action obtained by Subordinated Creditor in breach of this Section 2.4 shall in any event be held in trust by it for the benefit of the Senior Creditor Representative and Senior Creditors and promptly be paid or delivered to the Senior Creditor Representative for the benefit of Senior Creditors in the form received until all Senior Debt is paid in full in cash and all commitments to lend under the Senior Loan Documents shall have been terminated.

Section 2.5 Incorrect Payments Held in Trust. If any Distribution on account of the Subordinated Debt not permitted to be made by the Borrower or accepted, taken or claimed by Subordinated Creditor under this Agreement is made and received by Subordinated Creditor, whether from Borrower or any guarantor, such Distribution shall not be commingled with any of the assets of Subordinated Creditor, shall be held in trust by Subordinated Creditor for the benefit of the Senior Creditor Representative and the Senior Creditors and shall be promptly paid over to the Senior Creditor Representative for application (in accordance with the Senior Loan Documents) to the payment of the Senior Debt then remaining unpaid, until all of the Senior Debt is paid in full.

(a) The Subordinated Creditor shall not sell, assign, pledge, dispose of or otherwise transfer all or any portion of the Subordinated Debt or any Subordinated Loan Document: (i) without giving at least 3 Business Days’ prior written notice of such action to the Senior Creditor Representative, (ii) if the transferee thereof is not a Permitted Investor (as defined in the Senior Credit Agreement), without the prior written consent of the Senior Creditor Representative, and (iii) unless, prior to the consummation of any such action, the transferee thereof shall execute and deliver to the Senior Creditor Representative an agreement substantially identical to this Agreement, providing for the continued subordination of the Subordinated Debt to the Senior Debt as provided herein and for the continued effectiveness of all of the rights of the Senior Creditor Representative and Senior Creditors arising under this Agreement.

(b) Notwithstanding the failure of any transferee to execute or deliver an agreement substantially identical to this Agreement, the subordination effected hereby shall survive any sale, assignment, pledge, disposition or other transfer of all or any portion of the Subordinated Debt, and the terms of this Agreement shall be binding upon the successors and assigns of Subordinated Creditor.

Section 2.8 Prohibition on Contesting Senior Debt. The Subordinated Creditor (solely in its capacity as such and not in its capacity as the direct or indirect owner of the equity interests in the Borrower or in any other capacity) agrees that it shall not (and hereby waives any right to) contest, or support any other Person in contesting, in any proceeding (including any Proceeding): (i) the validity or enforceability of any Senior Loan Document or the Senior Debt, (ii) the validity, perfection, priority or enforceability of any liens, mortgages, assignments and security interests granted with respect to the Senior Debt or (iii) any foreclosure proceeding or action brought by the Senior Creditor Representative or the Senior Creditors or any other exercise by the Senior Creditor Representative or the Senior Creditors of any rights and remedies under the Senior Loan Documents or otherwise.

Section 3.3 Subordination Not Affected . All rights and interests of the Senior Creditor Representative and the Senior Creditors hereunder, and all agreements and obligations of the Subordinated Creditor and the Borrower under this Agreement, shall remain in full force and effect irrespective of:

(iii)    any taking, exchange, release or non perfection of any other collateral, or any taking, release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Senior Debt;

(iv)    any manner of application of collateral, or proceeds thereof, to all or any of the Senior Debt, or any manner of sale or other disposition of any collateral for all or any of the Senior Debt or any other assets of the Borrower, any of its Subsidiaries or the MLP;

(v)    any change, restructuring or termination of the corporate structure or existence of the Borrower, any of its Subsidiaries or the MLP; or

(vi)    any other circumstance which might otherwise constitute a defense available to, or a discharge of, the Borrower or a subordinated creditor.

The provisions of this Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Senior Debt is rescinded or must otherwise be returned by the Senior Creditor Representative or any Senior Creditor upon the occurrence of a Proceeding with respect to the Borrower or otherwise, all as though such payment had not been made.
