(B) In the event that the Borrower shall make or Subordinated Lender shall collect any payment on account of the principal of, premium or interest on or any other amounts due under the Subordinated Indebtedness in contravention of this Section 6, such payments shall be paid over and delivered to the Senior Lender immediately upon receipt thereof. (C) In the event that any failure of the Borrower to make or the Subordinated Lender to receive any payment with respect to the Subordinated Indebtedness as a result of the provisions of this Section 6 shall be deemed a default under the Subordinated Documents, such event shall not give rise to any right of Subordinated Lender to exercise any Subordinated Lender Remedies, any provision of the Subordinated Documents to the contrary notwithstanding. 7. Forbearance of Legal Remedies. Until all of the Senior Indebtedness has been Finally Paid, the Subordinated Lender shall not exercise any Subordinated Lender Remedies or other remedies it may have for a default under the Subordinated Documents.

Upon any distribution of assets of Borrower in any dissolution, winding up, liquidation or reorganization of Borrower (whether in bankruptcy, insolvency or receivership proceedings or upon an assignment for the benefit of creditors or otherwise) tending toward liquidation of the business and assets of Borrower or reorganization of the business affairs of the Borrower: (A) the holder of all Senior Indebtedness shall first be entitled to receive payment in full (or to have such payment duly provided for in a manner previously agreed upon or otherwise satisfactory to it) of the principal thereof, and premium and interest due thereon, and other amounts payable comprising such Senior Indebtedness, before the Subordinated Lender is entitled to receive any payment on account of the principal of, premium or interest on or any other amounts due under the Subordinated Indebtedness; and (B) any payment or distribution of assets of the Borrower of any kind or character, whether in cash, property or securities, to which the Subordinated Lender would be entitled except for these provisions, shall be paid by the liquidating trustee or agent or other person making such payment or distribution directly to the holder of the Senior Indebtedness, to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution or provision therefor to the holders of such Senior Indebtedness. The Borrower shall give prompt written notice to the Senior Lender and the Subordinated Lender of any dissolution, winding up, liquidation or reorganization of Borrower or any assignment for the benefit of any of the creditors of Borrower tending toward the liquidation of the business and assets of Borrower or the reorganization of the business affairs of Borrower. 9. Obligation of Borrower Unconditional. Nothing contained herein or in the Loan Agreement and/or any of the Loan Documents is intended to or shall impair, as between the Borrower and the Subordinated Lender only, the obligation of the Borrower, which is absolute and unconditional, to pay to the holder of the Subordinated Indebtedness the Subordinated Indebtedness as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the Subordinated Lender and creditors of the Borrower other than the Senior Lender. 10. Subordination Rights Not Impaired by Acts or Omissions of Borrower or Holder of Senior Indebtedness. No right of any present or future holder of any Senior Indebtedness to enforce subordination as provided herein shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Borrower; by any act or failure to act, which act or failure is in good faith, by any such holder; by any act or failure to act by any other holder of the Senior Indebtedness; or by any noncompliance by the Borrower with the terms hereof, regardless of any knowledge thereof which any such holder may have or be otherwise charged with. Subordinated Lender hereby agrees that the Senior Lender shall have the right, but shall have no obligation, to cure any default under the Subordinated Documents. Further, Subordinated Lender hereby agrees that Subordinated Lender shall not be released, nor shall Subordinated Lender’s obligation hereunder be in anyway diminished, by any of the following: (A) the exercise or the failure to exercise by Senior Lender or any other Lender of any rights or
7 remedies conferred on it or them under the Loan Agreement, any Loan Documents, hereunder or existing at law or otherwise, or against any of Borrower’s Property; (B) the commencement of an action at law or the recovery of a judgment at law against Borrower or any obligor (“Obligor”) for the performance of the Senior Indebtedness and the enforcement thereof through levy or execution or otherwise; (C) the taking or institution or any other action or proceeding against Borrower or any Obligor; or (D) any delay in taking, pursuing, or exercising any of the foregoing actions, rights, powers, or remedies (even though requested by Subordinated Lender) by Senior Lender or anyone acting for Senior Lender. Without limiting the generality of the foregoing, and anything else contained herein to the contrary notwithstanding, Senior Lender or any other Lender, from time to time, without prior notice to or the consent of Subordinated Lender, may take all or any of the following actions without in any manner affecting or impairing the obligation or liability of Subordinated Lender hereunder: (i) obtain a lien or a security interest in any property to secure any of the Senior Indebtedness for the benefit of the Senior Lender and the other Lenders; (ii) obtain the primary and secondary liability of any party or parties with respect to any of the Senior Indebtedness; (iii) increase the amount of the Senior Loan or renew, extend, or otherwise change the time for payment of the Senior Loan or any installment thereof for any period; (iv) release or compromise any liability of any nature of any person or entity with respect to the Senior Indebtedness; (v) exchange, enforce, waive, release, and apply Borrower’s Property and direct the order or manner of sale thereof as Senior Lender or any other Lender may in its discretion determine; (vi) enforce its rights hereunder, whether or not Senior Lender or any other Lender shall proceed against any other person or entity; (vii) exercise its rights to consent to any action or non-action of Borrower which may violate the covenants and agreements contained in the Loan Agreement or any Loan Documents, with or without consideration, on such terms and conditions as may be acceptable to it; or (viii) exercise any of its rights conferred by the Loan Agreement, any Loan Documents or by law. 11. Authority to Act for Subordinated Lender. Until the Senior Indebtedness has been Finally Paid, in the event an Insolvency Proceeding shall occur and be continuing, Subordinated Lender shall file all claims it may have against Borrower and shall direct the debtor in possession or trustee in bankruptcy, as appropriate, to pay over to Senior Lender all amounts due to Subordinated Lender on account of the Subordinated Indebtedness until the Senior Indebtedness has been Finally Paid. If Subordinated Lender fails to file such claims as requested by Senior Lender, Senior Lender may file such claims on Subordinated Lender’s own behalf. Subordinated Lender acknowledges and agrees that so long as any Senior Indebtedness is owed to Senior Lender by Borrower, Senior Lender shall have the right to vote the Subordinated Lender’s claim in any Insolvency Proceeding, and Subordinated Lender shall execute any and all future documents and/or instruments requested by Senior Lender at any time to further evidence and confirm such right. Until the Senior Indebtedness has been Finally Paid, in the event an Insolvency Proceeding shall occur and be continuing, Subordinated Lender hereby (i) expressly consents to the granting by Borrower to Senior Lender of senior liens and priorities in connection with any post-petition financing of Borrower by Senior Lender and/or the use of cash collateral and (ii) agrees that adequate notice of such financing to Subordinated Lender shall have been provided if Subordinated Lender received notice in accordance with Section 11 hereof five (5) Business Days prior to the entry of any order approving such cash collateral usage or financing. In the event that Subordinated Lender has or at any time acquires any security for the Subordinated Indebtedness, Subordinated Lender agrees not to assert any right it may have to “adequate protection” of its interest in such security in any Insolvency Proceeding and agrees that it will not seek to have the
8 automatic stay lifted with respect to such security, in each case without the prior written consent of Senior Lender. Subordinated Lender waives any claim or defense Subordinated Lender may now or hereafter have arising out of the election by the Senior Lender in any Insolvency Proceeding instituted under Chapter 11 of the Bankruptcy Code, of the application of Section 1111(b)(2) of the Bankruptcy Code, and/or any use of cash collateral, any borrowing or any grant of a security interest under Sections 363 and/or 364 of the Bankruptcy Code by Borrower, as debtor-in- possession. To the extent that Senior Lender receives payments on, or proceeds of collateral for, the Senior Indebtedness which are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law, or equitable cause, then as between Senior Lender and Subordinated Lender hereunder, to the extent of such payment or proceeds received, the Senior Indebtedness, or part thereof, intended to be satisfied shall be revived and continue in full force and effect as if such payments or proceeds had not been received by the Senior Lender. 12. Waivers. Borrower and Subordinated Lender each hereby waives, to the fullest extent permitted by law, any defense based on the adequacy of a remedy at law which might be asserted as a bar to the remedy of specific performance of this Agreement in any action brought therefor by Senior Lender. To the fullest extent permitted by law and except as to any notices specified in this Agreement, notices regarding the intended sale or disposition of any portion of the Collateral by Senior Lender, or any notice which may not be waived in accordance with the UCC, Borrower and Subordinated Lender each hereby further waives: presentment, demand, protest, notice of protest, notice of default or dishonor, notice of payment or nonpayment and any and all other notices and demands of any kind in connection with all negotiable instruments evidencing all or any portion of the Senior Indebtedness or the Subordinated Indebtedness to which Borrower or Subordinated Lender may be a party; prior notice of and consent to any loans made, extensions granted or other action taken in reliance thereon; and all other demands and notices of every kind in connection with this Agreement, the Senior Indebtedness or the Subordinated Indebtedness. Subordinated Lender consents to any release, renewal, extension, compromise or postponement of the time of payment of the Senior Indebtedness, to any substitution, exchange or release of collateral therefor, and to the addition or release of any person primarily or secondarily liable thereon. 13. No Waiver. Neither the failure nor any delay on the part of Senior Lender to exercise any right, remedy, power or privilege hereunder shall operate as a waiver thereof or give rise to an estoppel, nor be construed as an agreement to modify the terms of this Agreement, nor shall any single or partial exercise of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence. No waiver by a party hereunder shall be effective unless it is in writing and signed by the party making such waiver, and then only to the extent specifically stated in such writing. 14. Default. If any material representation or warranty of Borrower or Subordinated Lender in this Agreement or in any instrument evidencing, securing or relating to the Senior Indebtedness proves to have been materially false when made, or, in the event of a material breach by either the Borrower or Subordinated Lender in the performance of any of the material terms of this Agreement, or any instrument or agreement evidencing, securing or relating to the Senior Indebtedness, all of the Senior Indebtedness shall, at the option of Senior Lender, become
9 immediately due and payable without presentment, demand, protest, or notices of any kind, notwithstanding any time or credit otherwise allowed. At any time Subordinated Lender fails to comply with any provision of this Agreement that is applicable to Subordinated Lender, Senior Lender may demand specific performance of this Agreement, whether or not Borrower has complied with this Agreement, and may exercise any other remedy available at law or equity. 15. Amendment of the Subordinated Documents. Subordinated Lender agrees that it will not, without the consent of the Senior Lender, amend the Subordinated Documents, so as to modify the financial terms thereof (including, without limitation, the amount of principal, rate of interest, dividends, fees and prepayment premiums, if any), extend the maturity thereof, add or change any covenants in a manner materially more restrictive to the Borrower, or effect any other modification to the Subordinated Documents, which would be materially adverse to the Senior Lender. 16. Inconsistent or Conflicting Provisions. In the event a provision of the Loan Agreement, any of the Loan Documents or the Subordinated Documents, is inconsistent or conflicts with the provisions of this Agreement, the provisions of this Agreement shall govern and prevail. 17. Notices. Any written notice, consent or other communication provided for in this Agreement shall be delivered personally (effective upon delivery), via facsimile (effective upon confirmation of transmission), via overnight courier (effective the next Business Day after dispatch if instructed to deliver on next Business Day) or via U.S. Mail (effective three (3) days after mailing, postage prepaid, first class) to each party at its address(es) and/or facsimile number(s) set forth below its signature, or to such other address as either party shall specify to the other in writing from time to time. 18. Benefit. Subordinated Lender represents and warrants that the making of the Senior Loan and the continued extension of credit under such Senior Loan will benefit Subordinated Lender in that Subordinated Lender is financially interested in Borrower and will benefit from the financial success of Borrower. Subordinated Lender acknowledges that Senior Lender would not continue to make credit available under the Senior Loan but for the execution of this Agreement. Therefore, Subordinated Lender has received good, sufficient and adequate consideration for the making of this Agreement. 19. Entire Agreement. This Agreement constitutes and expresses the entire understanding among the parties hereto with respect to the subject matter hereof, and supersedes all prior and contemporaneous agreements and understandings, inducements or conditions, whether express or implied, oral or written. Neither this Agreement nor any portion or provision hereof may be changed, waived or amended orally or in any manner other than by an agreement in writing signed by Senior Lender and Subordinated Lender; provided, however, any such change, waiver or amendment shall be binding upon the Borrower by its written consent thereto. 20. Additional Documentation. Borrower and Subordinated Lender shall execute and deliver to Senior Lender such further instruments and shall take such further action as Senior Lender may at any time or times reasonably request in order to carry out the provisions and intent of this Agreement.

Borrower agrees to pay Senior Lender on demand all expenses of every kind, including reasonable attorneys’ fees, that Senior Lender may incur in enforcing any of its rights against Borrower under this Agreement. Subordinated Lender agrees to pay Senior Lender on demand all expenses of every kind, including reasonable attorneys’ fees, that Senior Lender may incur in enforcing any of its rights against Subordinated Lender under this Agreement. 22. Successors and Assigns. This Agreement shall inure to the benefit of Senior Lender, its successors and assigns, and shall be binding upon Borrower and its successors and assigns, and Subordinated Lender and its successors and assigns, including without limitation, any subsequent holders of the Note. Senior Lender, without prior notice or consent of any kind, may sell, assign or transfer the Senior Indebtedness, and in such event each and every immediate and successive assignee or transferee thereof may be given the right by Senior Lender to enforce this Agreement in full against Borrower and Subordinated Lender, by suit or otherwise, for its own benefit, provided that such successor, assignee or transferee agrees to be bound by the terms of this Agreement. 23. Covenant Not to Challenge. This Agreement has been negotiated by the parties with the expectation and in reliance upon the assumption that the instruments and documents evidencing the Senior Indebtedness are valid and enforceable. In determining whether to enter into this Agreement, Subordinated Lender has assumed such validity and enforceability, and has agreed to the provisions contained herein, without relying upon any reservation of a right to challenge or call into question such validity or enforceability. As between Senior Lender and Subordinated Lender, Subordinated Lender hereby covenants and agrees, to the fullest extent permitted by law, that it shall not (x) initiate in any proceeding a challenge to the validity or enforceability of the documents and instruments evidencing the Senior Indebtedness, the right of Senior Lender to be paid the Senior Indebtedness in full in cash, or the priority or amount of Senior Lender’s claim in respect of the Senior Indebtedness (y) instigate other parties to raise any such challenges, (z) participate in or otherwise assert any such challenges which are raised by other parties. 24. Termination of Agreement. This Agreement shall continue and shall be irrevocable until the date all of the Senior Indebtedness has been Finally Paid by Borrower or otherwise discharged and released by the Senior Lender. 25. Reinstatement. The obligations of Subordinated Lender under this Agreement shall continue to be effective, or be reinstated, as the case may be, if at any time any payment in respect of any Senior Indebtedness is rescinded or must otherwise be restored or returned by Senior Lender by reason of any bankruptcy, reorganization, arrangement, composition or similar proceeding or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, Borrower or any substantial part of its property, or otherwise, all as though such payment had not been made. 26.
