NOW, THEREFORE, in consideration of the foregoing and the mutual agreements herein contained, and for other good and valuable consideration, the receipt and adequacy of which are hereby expressly acknowledged, the parties hereto agree as follows:

SECTION 3. Incorporation by Reference. The terms and conditions of the Original Agreement are expressly incorporated herein by reference as if fully set forth herein.

SECTION 4. Agreement to be Bound. The Transferee hereby (i) agrees to bound by the Original Agreement as if Transferee were named as Purchaser therein, except that the parties agree that Transferee has no obligation under Section 1 (Agreement to Purchase), as if such Transferee had executed the Original Agreement as a Purchaser (as defined therein) on the date of the Original Agreement, and (ii) affirms that the representations and warranties of the Purchaser as set forth in the Original Agreement are true, complete and correct as if given by the Transferee on the date hereof;

Capitalized terms used in this Section 5 shall have the meaning ascribed to such term in the Original Agreement.

SECTION 6.

[FOR A. LASZLO: Agreement to Vote and Irrevocable Proxy.

(a) The Transferee hereby agrees that from and after the date hereof through the consummation of the Business Combination (as defined in the Original Agreement), with respect to any matter upon which the stockholders of the Corporation are entitled to vote, that such Transferee shall vote all Transferred Shares as directed by the Transferor and in accordance with the terms of the Original Agreement; provided, that where a vote pursuant to the direction of the Transferor would cause Transferee to be in violation of Section 9 (Voting of Shares) of the Original Agreement, this Section 6 shall not govern.

(b) The Transferee hereby constitutes and appoints any authorized officer of Transferor its true and lawful proxy and attorney-in-fact to vote all Transferred Shares which Transferee beneficially owns as of the date hereof, with respect to any matter upon which the stockholders of the Corporation are entitled to vote.

The proxy and power of attorney granted herein shall be irrevocable as of the date hereof through the consummation of the Business Combination, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke all prior proxies granted by the Transferee. The Transferee shall not grant any proxy to any person which conflicts with the proxy granted herein, and any attempt to do so shall be void. The power of attorney granted herein is a durable power of attorney and shall survive the disability or incompetence of the Transferee.

In the event that the Transferee fails for any reason to vote his Transferred Shares in accordance with the requirements of Section 6(a) hereof, then any authorized officer of the Transferor shall have the right to vote such shares on behalf of the Transferee in accordance with the provisions of this Section 6(b).]

[FOR K. BOYDA: [Intentionally Omitted].]
