Capitalized terms used but not defined in this Agreement have the meanings ascribed thereto in the Merger Agreement (as defined below).

WHEREAS, concurrently with the execution of this Agreement, AuthenTec, Inc., a Delaware corporation (the “Company”), Parent and Merger Sub are entering into an Agreement and Plan of Merger of even date herewith (the “Merger Agreement”), which provides, among other things, for Merger Sub to merge with and into the Company, with the Company continuing as the surviving corporation and a wholly-owned subsidiary of Parent (the “Merger”);

WHEREAS, as of the date hereof, Stockholder is the record and beneficial owner of [            ] shares of Company Common Stock (such shares of Company Common Stock, together with any other shares of Company Common Stock acquired by Stockholder after the date hereof, being collectively referred to herein as the “Stockholder Shares”); and

WHEREAS, as a condition to their willingness to enter into the Merger Agreement, Parent and Merger Sub have required that Stockholder enter into this Agreement and, in order to induce Parent and Merger Sub to enter into the Merger Agreement, Stockholder is willing to enter into this Agreement.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, and intending to be legally bound hereby, Parent, Merger Sub and Stockholder agree as follows:

1. Representations and Warranties of Stockholder. Stockholder hereby represents and warrants to Parent and Merger Sub as follows:

This Agreement has been duly executed and delivered by Stockholder and, assuming due and valid authorization, execution and delivery hereof by Parent and Merger Sub, constitutes a valid and binding obligation of Stockholder, enforceable against Stockholder in accordance with its terms, except that such enforceability (i) may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar Laws of general application affecting or relating to the enforcement of creditors’ rights generally and (ii) is subject to general principles of equity, whether considered in a proceeding at Law or in equity.

Neither the execution of this Agreement by Stockholder nor the consummation of the transactions contemplated hereby will result in a breach or violation of the terms of any agreement to which the Stockholder is bound or is a party or any Law or Order applicable to Stockholder, except for such breaches or violations as would not, individually or in the aggregate, reasonably be expected to prevent or materially delay the performance by Stockholder of any of his obligations under this Agreement.

(c) Ownership of Shares. Except as set forth on Exhibit A hereto, Stockholder owns, beneficially and of record, all of the Stockholder Shares free and clear of any proxy, voting restriction, adverse claim or other Lien (other than restrictions in favor of Parent and Merger Sub pursuant to this Agreement and except for such transfer restrictions of general applicability as may be provided under federal and state securities Laws, collectively “Permitted Liens”). Without limiting the foregoing, except as set forth on Exhibit A hereto and for Permitted Liens, Stockholder has sole voting power and sole power of disposition with respect to all Stockholder Shares, with no restrictions on Stockholder’s rights of voting or disposition pertaining thereto, and no Person other than Stockholder has any right to direct or approve the voting or disposition of any Stockholder Shares.
