(d) This Surety Agreement constitutes the valid and binding obligation of the Undersigned enforceable in accordance with its terms except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and similar laws affecting the enforcement of creditors' rights generally and general equitable principles. (e) This Surety Agreement promotes and furthers the business and interests of the Undersigned, and the incurrence of the Obligations by Borrower and creation of the obligations hereunder will result in financial benefit to the Undersigned. 2. The Undersigned hereby waives all notices with respect to this Surety Agreement, including without limitation, notices of (a) acceptance of this Surety Agreement, (b) the existence or incurring from time to time of any Obligations guaranteed hereunder, (c) the existence of any Event of Default, the making of demand, or the taking of any action by you, under the Loan Agreement, and (d) demand and default hereunder. 3.

The liability of the Undersigned hereunder is absolute and unconditional and shall not be reduced, impaired or affected in any way by reason of (a) any failure to obtain, retain or preserve, or the lack of prior enforcement of, any rights against any person or persons (including, without limitation, Borrower, the Undersigned, or any other obligor) or in any property, (b) the invalidity or unenforceability of any Obligations or rights in any Collateral, (c) any delay in making demand upon Borrower (or any other obligor), or any delay in enforcing, or any failure to enforce, any rights against Borrower, any other obligor or in any Collateral even if such rights are thereby lost, (d) any failure, neglect or omission on your part to obtain or perfect any lien upon, protect, exercise rights against, or realize on, any property of Borrower, the Undersigned or any other party securing the Obligations, (e) the existence or nonexistence of any defenses which may be available to Borrower with respect to the Obligations (other than the defense of payment), (f) any failure to proceed against Borrower or any Collateral in a commercially reasonable manner, or (g) the commencement of any bankruptcy, reorganization, liquidation, dissolution or receivership proceeding or case filed by or against Borrower. 5. If any or all payments made from time to time to you with respect to any Obligation hereby guaranteed are recovered from, or repaid by, you in whole or in part in any bankruptcy, reorganization, insolvency or similar proceeding instituted by or against Borrower, this Surety Agreement shall continue to be fully applicable to such Obligation to the same extent as if the recovered or repaid payment(s) had never been originally made on such Obligation. 2 6. All rights and remedies hereunder and under the Loan Agreement, and related agreements, are cumulative and not alternative, and you may proceed in any order from time to time against Borrower, the Undersigned and/or any other obligor of Borrower's Obligations and their respective assets. 7. Any and all rights of any nature of the Undersigned to subrogation, reimbursement or indemnity and any right of the Undersigned to recourse to any assets or property of Borrower for any reason shall be unconditionally subordinated to all of your rights under the Loan Agreement and the Undersigned shall not at any time exercise any of such rights unless and until all of the Obligations have been indefeasibly paid and satisfied in full. 8. Your books and records of any and all of Borrower's Obligations, absent manifest error, shall be prima facie evidence against the Undersigned of the indebtedness due you or to become due to you hereunder. 9. This Surety Agreement shall constitute a continuing surety obligation and you may continue to act in reliance hereon until all of the Obligations have been indefeasibly paid and satisfied in full. You shall not have any obligation to proceed against, or exhaust any or all of your rights against, Borrower prior to proceeding against the Undersigned hereunder. 10. The Undersigned agrees that you shall have a right of setoff against any and all property of the Undersigned now or at any time in your possession, including without limitation deposit accounts, and the proceeds thereof, as security for the obligations of the Undersigned hereunder. 11. If an Event of Default occurs and is continuing under the Loan Agreement, then all of the Undersigned's Obligations to you hereunder shall, at your option, become immediately due and payable and you may at any time and from time to time take any and/or all actions and enforce all rights and remedies available hereunder or under applicable law to collect the Undersigned's liabilities hereunder. 12. Failure or delay in exercising any right or remedy against the Undersigned hereunder shall not be deemed a waiver thereof or preclude the exercise of any other right or remedy hereunder. No waiver of any breach of or provision of this Surety Agreement shall be construed as a waiver of any subsequent breach or of any other provision. The invalidity or unenforceability of any provision hereof shall not affect the remaining provisions which shall remain in full force and effect. 13. This Surety Agreement shall (a) be legally binding upon the Undersigned and the Undersigned's successors and assigns, provided that the Undersigned's obligations hereunder may not be delegated or assigned without your prior written consent and (b) benefit any and all of your successors and assigns. 14. This Surety Agreement embodies the whole agreement and understanding of the parties hereto relative to the subject matter hereof. No modification of any provision hereof shall be enforceable unless approved by you in writing. 3 15. This Surety Agreement shall in all respects be interpreted, construed and governed in accordance with the substantive laws of the jurisdiction set forth in Section 9.1 of the Loan Agreement.
