For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

5. Guaranty Absolute and Unconditional. (a) Guarantor hereby agrees that its obligations under this Guaranty constitute a guarantee of payment when due and not of collection. Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by Buyer upon this Guaranty or acceptance of this Guaranty; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Guaranty; and all dealings between Seller and Guarantor, on the one hand, and Buyer, on the other hand, shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guaranty. Guarantor waives promptness, diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon Seller or the Guaranty with respect to the Obligations. This Guaranty shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (i) the validity, regularity or enforceability of any agreement, any of the Obligations or any collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by Buyer, (ii) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by Seller against Buyer, (iii) any requirement that Buyer exhaust any right to take any action against Seller or any other Person prior to or contemporaneously with proceeding to exercise any

right against Guarantor under this Guaranty or (iv) any other circumstance whatsoever (with or without notice to or knowledge of Seller and Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of Seller for the Obligations or of Guarantor under this Guaranty, in bankruptcy or in any other instance. When pursuing its rights and remedies hereunder against Guarantor, Buyer may, but shall be under no obligation, to pursue such rights and remedies that Buyer may have against Seller or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by Buyer to pursue such other rights or remedies or to collect any payments from Seller or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of Seller or any such other Person or any such collateral security, guarantee or right of offset, shall not relieve Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of Buyer against Guarantor. This Guaranty shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon Guarantor and its successors and assigns thereof, and shall inure to the benefit of Buyer and its permitted successors, endorsees, transferees and assigns, until all the Obligations and the obligations of Guarantor under this Guaranty shall have been satisfied by payment in full.

(b) Without limiting the generality of the foregoing, Guarantor hereby agrees, acknowledges, and represents and warrants to Buyer as follows:

(i) Guarantor hereby waives any defense arising by reason of, and any and all right to assert against Buyer any claim or defense based upon, an election of remedies by Buyer which in any manner impairs, affects, reduces, releases, destroys and/or extinguishes Guarantor’s subrogation rights, rights to proceed against Seller or any other guarantor for reimbursement or contribution, and/or any other rights of Guarantor to proceed against Seller, any other guarantor or any other person or security.

(ii) Guarantor is presently informed of the financial condition of Seller and of all other circumstances which diligent inquiry would reveal and which bear upon the risk of nonpayment of the Obligations. Guarantor hereby covenants that it will make its own investigation and will continue to keep itself informed about the financial condition of Seller, the status of other guarantor, if any, of all other circumstances which bear upon the risk of nonpayment and that it will continue to rely upon sources other than Buyer for such information and will not rely upon Buyer for any such information. Absent a written request for such information by Guarantor to Buyer, Guarantor hereby waives the right, if any, to require Buyer to disclose to Guarantor any information which Buyer may now or hereafter acquire concerning such condition or circumstances including, but not limited to, the release of or revocation by any other guarantor.

(iii) Guarantor has independently reviewed the Transaction Documents and related agreements and has made an independent determination as to the validity and enforceability thereof, and in executing and delivering this Guaranty to Buyer, Guarantor is not in any manner relying upon the validity, and/or enforceability, and/or attachment, and/or perfection of any liens or security interests of any kind or nature granted by Seller or any other guarantor to Buyer, now or at any time and from time to time in the future.

6. Reinstatement. This Guaranty shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by Buyer upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Seller or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for Seller or any substantial part of the property of Seller, or otherwise, all as though such payments had not been made.
