every jurisdiction where its assets are located and wherever necessary to carry out its business and operations, except in jurisdictions where the failure to be so qualified or in good standing has not had, and could not be reasonably expected to have, a Material Adverse Effect; and

2.The execution, delivery and performance of this Sixth Amendment has been duly authorized by all necessary action on the part of each Note Party that is a party hereto.

D. OTHER AGREEMENTS

1.Continuing Effectiveness of Note Documents.  As amended hereby, all terms of the Note Purchase Agreement and the other Note Documents shall be and remain in full force and effect and shall constitute the legal, valid, binding and enforceable obligations of the Note Parties party thereto.  To the extent any terms and conditions in any of the other Note Documents shall contradict or be in conflict with any terms or conditions of the Note Purchase Agreement, after giving effect to this Sixth Amendment, such terms and conditions are hereby deemed modified and amended accordingly to reflect the terms and conditions of the Note Purchase Agreement as modified and amended hereby. Upon the effectiveness of this Sixth Amendment such terms and conditions are hereby deemed modified and amended accordingly to reflect the terms and conditions of the Note Purchase Agreement as modified and amended hereby.

2.Reaffirmation of Guaranty.  Each Guarantor consents to the execution and delivery by the Note Parties of this Amendment and the consummation of the transactions described herein, and ratifies and confirms the terms of the Guaranty to which such Guarantor is a party with respect to the indebtedness now or hereafter outstanding under the Note Purchase Agreement as amended hereby and all promissory notes issued thereunder. Each Guarantor acknowledges that, notwithstanding anything to the contrary contained herein or in any other document evidencing any indebtedness of the Note Parties to the Purchasers or any other obligation of the Note Parties, or any actions now or hereafter taken by the Purchasers with respect to any obligation of the Note Parties, the Guaranty to which such Guarantor is a party (i) is and shall continue to be a primary obligation of such Guarantor, (ii) is and shall continue to be an absolute, unconditional, continuing and irrevocable guaranty of payment, and (iii) is and shall continue to be in full force and effect in accordance with its terms.  Nothing contained herein to the contrary shall release, discharge, modify, change or affect the original liability of any Guarantor under the Guaranty to which such Guarantor is a party.

Each Note Party hereby acknowledges that, as of the date hereof, the security interests and liens granted to Collateral Agent and the Purchasers under the Note Purchase Agreement and the other Note Documents are in full force and effect, are properly perfected and are enforceable in accordance with the terms of the Note Purchase Agreement and the other Note Documents.

4.Reservation of Rights. The parties agree that this Sixth Amendment does not constitute a waiver of any right, power, privilege, claim or remedy that the Purchaser would be entitled to exercise as a result of any and all events that may have occurred or that, with the passage of time and/or the giving of notice would constitute an Event of Default under the Note Documents and other defaults that may have occurred under one or more of the Note Documents or may occur from time to time after the date hereof. Accordingly, the Company is hereby notified that:


(a)The Purchaser reserves the right to enforce and avail itself of any and all rights, powers, privileges, claims and remedies provided in the Note Purchase Agreement and the other Note Documents against the Company and any and all other obligors thereunder and the Collateral, including all rights and remedies available at law or in equity (individually and collectively, as the context may require, “Enforcement of Rights”).

(c)All of the rights, powers, privileges, claims and remedies of the Purchaser under the Note Documents and applicable law are hereby expressly reserved and neither any delay or omission by the Purchaser in the exercise of any Enforcement of Rights shall impair any such right, power, privilege, claim or remedy, or shall be construed to be a waiver thereof or any acquiescence therein. The Note Purchase Agreement and the other Note Documents shall continue to be, and shall remain, in full force and effect in accordance with their respective terms. There is no continuing agreement to forbear, or assurance of any forbearance, by the Purchaser and failure of the Purchaser to undertake any Enforcement of Rights at this time shall not constitute a course of dealing. For the avoidance of doubt, this Sixth Amendment does not constitute the exercise of any Enforcement of Rights, nor does it constitute a waiver or forbearance of any right of the Purchaser to, at any time, commence and undertake any Enforcement of Rights, which such rights are hereby expressly reserved by the Purchaser.

Any agreement, commitment, assurance, forbearance or intention of the Purchaser shall be effective only if in writing and duly executed by the Purchaser, as the case may be.
(e)Without limiting the generality of the foregoing, the Purchaser is under no obligation to honor any request for further waivers of any provision of the Note Purchase Agreement and this Sixth Amendment shall not be deemed to establish a course of conduct so as to justify an expectation by the Company that the Purchaser will agree to any such waivers and the Company shall comply strictly with all of the terms and conditions of the Note Documents from and after the date hereof.

5.Effect of Agreement.  Except as set forth expressly herein, all terms of the Note Purchase Agreement, as amended hereby, and the other Note Documents shall be and remain in full force and effect and shall constitute the legal, valid, binding and enforceable obligations of the Note Parties to the Purchasers and Collateral Agent.  The execution, delivery and effectiveness of this Sixth Amendment shall not operate as a waiver of any right, power or remedy of the Purchasers under the Note Purchase Agreement, nor constitute a waiver of any provision of the Note Purchase Agreement, in each case, except as expressly provided herein. This Sixth Amendment shall constitute a Note Document for all purposes of the Note Purchase Agreement.

6.Governing Law. This Sixth Amendment shall be governed by, and construed in accordance with, the internal laws of the State of New York and all applicable federal laws of the United States of America.

7.No Novation.This Sixth Amendment is not intended by the parties to be, and shall not be construed to be, a novation of the Note Purchase Agreement and the other Note Documents


or an accord and satisfaction in regard thereto.

8.Costs and Expenses.  The Note Parties agrees to pay on demand all costs and expenses of Purchaser and Collateral Agent in connection with the preparation, execution and delivery of this Amendment, including, without limitation, the reasonable fees and out-of-pocket expenses of outside counsel for Purchaser and Collateral Agent with respect thereto.

9.Counterparts.  This Sixth Amendment may be executed by one or more of the parties hereto in any number of separate counterparts, each of which shall be deemed an original and all of which, taken together, shall be deemed to constitute one and the same instrument.  Delivery of an executed counterpart of this Sixth Amendment by facsimile transmission, electronic transmission (including delivery of an executed counterpart in .pdf format) shall be as effective as delivery of a manually executed counterpart hereof.

10.Binding Nature.  This Sixth Amendment shall be binding upon and inure to the benefit of the parties hereto, their respective successors, successors-in-titles, and assigns.  No third party beneficiaries are intended in connection with this Sixth Amendment.

11.Entire Understanding.  This Sixth Amendment sets forth the entire understanding of the parties with respect to the matters set forth herein, and shall supersede any prior negotia­tions or agreements, whether written or oral, with respect thereto.
