Without limiting the generality of the foregoing, the Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any Other Loan Party to any Secured Party under or in respect of the Secured Documents but for the fact that they are unenforceable or not allowable due to the existence of an Insolvency or Liquidation Proceeding involving such other Loan Party.

(ii)The Guarantor, and by its acceptance of this Guaranty, the Term Loan Agent (on behalf of each Secured Party), hereby confirms that it is the intention of all such Persons that this Guaranty and the obligations of the Guarantor hereunder not constitute a fraudulent transfer, fraudulent conveyance or fraudulent incurrence of a debt for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guaranty and the obligations of the Guarantor hereunder.

The Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to any or all of the foregoing.

(iii)The Guarantor hereby unconditionally and irrevocably agrees that in the event any payment shall be required to be made to any Secured Party under this Guaranty or any other guaranty, the Guarantor will contribute, to the maximum extent permitted by law, such amounts to each Other Loan Party and each other guarantor of the Guaranteed Obligations so as to maximize the aggregate amount paid to the Secured Parties under or in respect of the Secured Documents.

b..Guaranty Absolute. To the fullest extent permitted by law, the Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Secured Documents. The obligations of the Guarantor under or in respect of this Guaranty are independent of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect of the Secured Documents, and a separate action or actions may be brought and prosecuted against the Guarantor to enforce this Guaranty, irrespective of whether any action is brought against any Borrower or any other Loan Party or whether any Borrower or any other Loan Party is joined in any such action or actions.

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

(iv)any manner of application of Collateral or any other collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the Guaranteed Obligations or any other Obligations of any Loan Party under the Secured Documents or any other assets of any Loan Party or any of its Subsidiaries;

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

(vi)any failure of any Lender to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party now or hereafter known to such Lender (the Guarantor waiving any duty on the part of the Lenders to disclose such information);

(vii)the failure of any other Person to execute or deliver this Agreement or any other guaranty or agreement or the release or reduction of liability of the Guarantor or other guarantor or surety with respect to the Guaranteed Obligations; or

(viii)any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Lender that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety (other than a defense by the Guarantor of Discharge of Obligations).

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Lender or any other Person upon the insolvency, bankruptcy or reorganization of any Borrower or any other Loan Party or otherwise, all as though such payment had not been made.
