Section 1. Amendments to Registration Rights Agreement.

(a) Section 3(a) of the Registration Rights Agreement is hereby deleted in its entirety and replaced with the following:

“(a) Right to Piggyback. Following the consummation of the Merger Agreement, whenever the Company proposes to register any of its securities under the Securities Act (other than (i) pursuant to a Demand Registration, (ii) in connection with registrations on Form S-4 or S-8 promulgated by the Securities and Exchange Commission or any successor or similar forms or (iii) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of Registrable Securities) and the registration form to be used may be used for the registration of Registrable Securities (a “Piggyback Registration”), the Company shall give prompt written notice (in any event within three Business Days after its receipt of notice of any request for registration on behalf of holders of the Company’s securities (other than by the Holders) to all Holders of its intention to effect such

Piggyback Registration and, subject to the terms of Section 3(c) and Section 3(d), shall include in such Piggyback Registration (and in all related registrations or qualifications under blue sky laws and in any related underwriting) all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 20 days after delivery of the Company’s notice. A Piggyback Registration shall not be considered a Demand Registration or a Shelf Offering Request for purposes of Section 2; provided, that at any time in which the Shelf Registration Statement pursuant to Section 2(c)(i) is effective, Section 3 shall be inapplicable in respect of any primary Registration of offering thereunder of securities by the Company.”

Section 2. Miscellaneous.

(a) Ratification. Except as expressly set forth herein, all terms and provisions contained in the Registration Rights Agreement shall remain in full force and effect.

(b) Governing Law. All issues and questions concerning the construction, validity, interpretation and enforcement of this Amendment shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

(c) Counterparts. This Amendment may be executed in multiple counterparts, any one of which need not contain the signature of more than one party, but all such counterparts taken together shall constitute one and the same agreement.

(d) Electronic Delivery. This Amendment, to the extent executed and delivered by means of a photographic, photostatic, facsimile or similar reproduction of such signed writing using a facsimile machine or electronic mail shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or electronic mail to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or electronic mail as a defense to the formation or enforceability of a contract and each such party forever waives any such defense.
