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.

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”).

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.

(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.

or an accord and satisfaction in regard thereto.

8.Costs and Expenses.

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.

The provisions of this paragraph shall be binding upon each Note Party and shall inure to the benefit of Releasees, and their respective heirs, executors, administrators, successors and assigns, and the other released parties set forth herein.

The provisions of this Section shall survive payment in full of the Obligations, full performance of the terms of this Sixth Amendment and the Note Documents, and/or Collateral Agent’s or each Purchaser’s actions to exercise any remedy available under the Note Documents or otherwise. Each Note Party warrants and represents that such Note Party is the sole and lawful owner of all right, title and interest in and to all of the claims released hereby and each Note Party has not heretofore voluntarily, by operation of law or otherwise, assigned or transferred or purported to assign or transfer to any person any such claim or any portion thereof.
