solely to an earlier date (in which case such representations and warranties are true and correct in all material respects on and as of such date); and no Default or Event of Default has occurred and is continuing on the Second Amendment Effective Date or would result from this Amendment becoming effective in accordance with its terms.

Each Borrower (i) is a corporation duly organized, validly existing and in good standing under the laws of the state of its organization, (ii) has all requisite power and authority to execute, deliver and perform this Amendment and the other Loan Documents to which it is a party being executed in connection with this Amendment, and to perform the Loan Agreement, as amended hereby, and (iii) is duly qualified to do business and is in good standing in each jurisdiction in which the character of the properties owned or leased by it or in which the transaction of its business makes such qualification necessary except where the failure to be so qualified reasonably could not be expected to have a Material Adverse Change.

Continued Effectiveness of the Loan Agreement. Except as otherwise expressly provided herein, the Loan Agreement and the other Loan Documents are, and shall continue to be, in full force and effect and are hereby ratified and confirmed in all respects, except that on and after the Second Amendment Effective Date (i) all references in the Loan Agreement to "this Agreement", "hereto", "hereof", "hereunder" or words of like import referring to the Loan Agreement shall mean the Loan Agreement as amended by this Amendment, and (ii) all references in the other Loan Documents to which any Borrower is a party to the "Loan Agreement", "thereto", "thereof", "thereunder" or words of like import referring to the Loan Agreement shall mean the Loan Agreement as amended by this Amendment. Except as expressly provided herein, the execution, delivery and effectiveness of this Amendment shall not operate as an amendment of any right, power or remedy of the Lender under the Loan Agreement or any other Loan Document, nor constitute an amendment of any provision of the Loan Agreement or any other Loan Document.
Counterparts. This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.

14
Headings. Section headings herein are included for convenience of reference only and shall not constitute a part of this Amendment for any other purpose.
Governing Law. This Amendment shall be governed by, and construed in accordance with, the law of the State of New York.
Costs and Expenses. The Borrowers jointly and severally agree to pay on demand all reasonable fees, costs and expenses of the Agent and each Lender in connection with the preparation, execution and delivery of this Amendment and the other related agreements, instruments and documents.
Amendment as Loan Document. Each Borrower hereby acknowledges and agrees that this Amendment constitutes a "Loan Document" under the Loan Agreement. Accordingly, it shall be an Event of Default under the Loan Agreement (i) if any representation or warranty made by a Borrower under or in connection with this Amendment shall have been untrue, false or misleading in any material respect when made or (ii) if Borrowers fail to perform, keep, or observe any term, provision, condition, covenant, or agreement contained in Section 12 of this Amendment.
Collateral. It is understood and agreed that all Collateral (as such term is amended pursuant to this Amendment) shall secure the Obligations under the Loan Documents. In addition, each Borrower confirms and agrees that to the extent that any Loan Document purports to assign or pledge to the Agent (on behalf of the Lenders), or to grant to the Agent (on behalf of the Lenders) a Lien on any collateral as security for the Obligations of such Borrower from time to time existing in respect of the Loan Agreement and the Loan Documents, such pledge, assignment and/or grant of a Lien is hereby ratified and confirmed in all respects. Without limiting the generality of the foregoing, each Borrower hereby grants to the Agent, for the benefit of the Lenders, a Lien on, and security interest in, all of such Borrower's Equipment, Investment Property, Negotiable Collateral and all other Collateral, as further collateral security for the Obligations.
Waiver of Jury Trial. EACH BORROWER, THE AGENT AND THE LENDERS HEREBY IRREVOCABLY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AMENDMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS.
