12. Certain Borrower Acknowledgments and Agreements.

(a) Each Borrower acknowledges that it will enjoy significant benefits from the business conducted by the other Borrowers because of, inter alia, their combined ability to bargain with other Persons including, without limitation, their ability to receive the Credit Facility on favorable terms granted by the Credit Agreement and other Loan Documents which would not have been available to an individual Borrower acting alone. Each Borrower has determined that it is in its best interest to procure the Credit Facility which each Borrower may utilize directly and which receive the credit support of the other Borrowers as contemplated by the Credit Agreement and the other Loan Documents.

(b) Lender has advised Borrowers that it is unwilling to enter into this Amendment, the Credit Agreement and the other Loan Documents and make available the Credit Facility extended hereby to any Borrower unless each Borrower agrees, among other things, to be jointly and severally liable for the due and proper payment of the Obligations of each Borrower under this Amendment, the Credit Agreement and the other Loan Documents. Each Borrower has determined that it is in its best interest and in pursuit of its purposes that it so induce Lender to extend credit pursuant to the Credit Agreement and the other documents executed in connection therewith (i) because of the desirability to each Borrower of the Credit Facility, the interest rates and the modes of borrowing available hereunder, (ii) because each Borrower may engage in transactions jointly with other Borrowers and (iii) because each Borrower may require, from time to time, access to funds under the Credit Agreement for the purposes herein set forth.

(c) Each Borrower has determined that it has and, after giving effect to the transactions contemplated by the Credit Agreement, this Amendment and the other Loan Documents (including, without limitation, the inter-Borrower arrangement set forth in this Section 12) will have, assets having a fair saleable value in excess of the amount required to pay its probable liability on its existing debts as they fall due for payment and that the sum of its debts is not and will not then be greater than all of its Property at a fair valuation, that such Borrower has, and will have, access to adequate capital for the conduct of its business and the ability to pay its debts from time to time incurred in connection therewith as such debts mature and that the value of the benefits to be derived by such Borrower from the access to funds under this Agreement (including, without limitation, the inter-Borrower arrangement set forth in this Section 12) is reasonably equivalent to the obligations undertaken pursuant hereto.

(d) Borrower Representative (on behalf of each Borrower) shall maintain records specifying (i) all Obligations incurred by each Borrower, (ii) the date of such incurrence, (iii) the date and amount of any payments made in respect of such Obligations and (iv) all inter-Borrower obligations pursuant to this Section 12. Borrower Representative shall make copies of such records available to Lender, upon request.

13. Maximum Amount of Joint and Several Liability. Notwithstanding any provisions of the Credit Agreement or this Amendment to the contrary, it is the intent of the parties hereto that the primary and secondary nature of the liabilities of the Borrowers, and the security interests granted by the Borrowers to secure the Obligations directly incurred by any Borrower not constitute a fraudulent conveyance under Section 548 of Chapter 11 of Title 11 of the United States Code (11 U.S.C. § 101, et seq.), as amended, or a fraudulent conveyance or fraudulent transfer under the applicable provisions of any fraudulent conveyance, fraudulent transfer or similar law of any state, nation or other governmental unit, as in effect from time to time or otherwise be rendered invalid or unenforceable due to the nature of the joint and several liability. Accordingly, Lender and Borrowers agree that if the Obligations of any Borrower, or any security interests granted by such Borrower securing the Obligations would, but for the application of this sentence, constitute a fraudulent conveyance or fraudulent transfer under Applicable Law, or would otherwise render such Borrower’s Obligations or the security interests granted herein invalid or unenforceable, the Obligations of such Borrower hereunder, as well as the security interests securing such Obligations, shall be valid and enforceable only to the maximum extent that would not cause such Obligations or security interests to constitute a fraudulent conveyance or fraudulent transfer under Applicable Law or otherwise result in such invalidity or unenforceability; provided however that each Borrower’s Obligations shall be presumptively valid and enforceable to their fullest extent in accordance with the terms hereof or thereof, as if this Section 13 were not a part of this Agreement.

14. Authorization of Borrower Representative by Borrowers.

(a) Each Borrower hereby irrevocably authorizes Borrower Representative to give notices, make requests, make payments, receive payments and notices, give receipts and execute agreements, make agreements or take any other action whatever on behalf of such Borrower under and with respect to any Loan Document and each Borrower shall be bound thereby. This authorization is coupled with an interest and shall be irrevocable, and Lender may rely on any notice, request, information supplied by Borrower Representative, every document executed by Borrower Representative, every agreement made by Borrower Representative or other action taken by Borrower Representative in respect of Borrowers or any thereof as if the same were supplied, made or taken by any or all Borrowers. Without limiting the generality of the foregoing, the failure of one or more Borrowers to join in the execution of any writing in connection herewith shall not, unless the context clearly requires, relieve any such Borrower from obligations in respect of such writing.

(b) Borrowers acknowledge that the credit provided under the Credit Agreement is on terms more favorable than any Borrower acting alone would receive and that each Borrower benefits directly and indirectly from all Advances thereunder. Each Borrower, shall be jointly and severally liable for all Obligations, regardless of inter alia, which Borrower requested (or received the proceeds of) a particular Advance.

15. Joint and Several Liability. The Revolving Loans made to the Borrowers shall be deemed jointly funded to, and received by, all of the Borrowers. Each Borrower jointly and severally agrees to pay, and shall be joint and severally liable for the payment and performance of all Obligations directly incurred by any other Borrower, regardless of whether such Borrower actually receives the proceeds of the indebtedness governed hereby or the benefit of any other extensions of credit hereunder. Each Borrower acknowledges and agrees that the joint and several liability of the Borrowers is provided as an inducement to Lender to provide loans and other financial accommodations to the Borrowers, and that each such Revolving Loan or other financial accommodation shall be deemed to have been done or extended by Lender in consideration of, and in reliance upon, the joint and several liability of the Borrowers. The joint and several liability of each Borrower hereunder is absolute, unconditional and continuing, regardless of the validity or enforceability of any of the Obligations, or the fact that a security interest or lien in any Collateral may not be enforceable or subject to equities or defenses or prior claims in favor of others, or may be invalid or defective in any way and for any reason. Each Borrower hereby waives: (a) all notices to which such Borrower may be entitled as a co-obligor with respect to the Obligations, including notice of (i) acceptance of this Amendment or the Credit Agreement, (ii) the making of Revolving Loans or other financial accommodations under this Agreement, or the creation or existence of the Obligations, and (iii) presentment, demand, protest, notice of protest and notice of non-payment; and (b) all defenses based on (i) any modification (or series of modifications) of the Credit Agreement, the other Loan Documents, that may create a substituted contract, or that may fundamentally alter the risks imposed on-such-Borrower hereunder,-(ii)-the-release- — of any other Borrower from its duties under the Credit Agreement and the other Loan Documents, or the extension of the time of performance of any other Borrower’s duties hereunder or thereunder, (iii) the taking, releasing, impairment or abandonment of any Collateral, or the settlement, release or compromise of the Obligations or any other Borrower’s liabilities with respect to all or any portion of the Obligations, or (iv) any other act (or any failure to act) that fundamentally alters the risks imposed on such Borrower by virtue of its joint and several liability hereunder. It is the intent of each Borrower by this paragraph to waive any and all suretyship defenses available to such Borrower with respect to the Obligations, whether or not specifically enumerated above. Borrowers acknowledge that the credit provided under the Credit Agreement is on terms more favorable than any Borrower acting alone would receive and that each Borrower benefits directly and indirectly from the Revolving Loans made hereunder. Each Borrower shall be jointly and severally liable for all Obligations regardless of, inter alia, which Borrower received proceeds of the Revolving Loans.
