3.Miscellaneous Provisions.

3.1.Effect of this Amendment. It is the intent of the parties hereto that this Amendment constitutes an amendment of the Existing Warrant Agreement. Except as otherwise expressly provided in this Amendment, this Amendment shall be deemed effective as of the Effective Time as if executed by all parties hereto on such date. Except as expressly provided in this Amendment, the terms of the Existing Warrant Agreement shall remain in full force and effect.

3.2.Severability. This Amendment shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Amendment or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Amendment a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

3.3.Applicable Law. The validity, interpretation, and performance of this Amendment and of the Warrants shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Amendment shall be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

3.4.Counterparts. This Amendment may be executed in any number of counterparts (which may include counterparts delivered by any standard form of telecommunication) and each of such

counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. The words “execution,” “signed,” “signature,” and words of like import in this Amendment or in any other certificate, agreement or document related to this Amendment, if any, shall include images of manually executed signatures transmitted by facsimile or other electronic format and other electronic signatures. The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law.

3.5.Effect of Headings. The section headings herein are for convenience only and are not part of this Amendment and shall not affect the interpretation thereof.
