Section 1.02. Irrevocable Proxy. Each Shareholder hereby revokes any and all previous proxies granted with respect to the Shares to the extent inconsistent herewith.

COVENANTS OF SHAREHOLDERS

Each Shareholder hereby covenants and agrees that:

Section 3.01. No Proxies for or Encumbrances on Shares. Except pursuant to the terms of this Agreement, such Shareholder shall not, without the prior written consent of Parent, directly or indirectly, (a) grant any proxies or enter into any voting trust or other agreement or arrangement with respect to the voting of any Shares; or (b) sell, assign, transfer, encumber or otherwise dispose of, or enter into any contract, option or other arrangement or understanding with respect to the direct or indirect sale, assignment, transfer, encumbrance or other disposition of, any Shares during the term of this Agreement. Shareholder shall not seek or solicit any such sale, assignment, transfer, encumbrance or other disposition

3

or any such contract, option or other arrangement or understanding and agrees to notify Parent promptly, and to provide all details requested by ▇▇▇▇▇▇, if Shareholder shall be approached or solicited, directly or indirectly, by any Person with respect to any of the foregoing. In no event shall the foregoing, or anything in this Agreement to the contrary, affect, restrict or otherwise limit Shareholder’s ability to directly or indirectly acquire additional Shares after the date hereof provided that any such additional Shares shall be subject to this Agreement and the restrictions, limitations and obligations of Shareholder pursuant hereto.

Section 3.02. Other Offers. Such Shareholder shall not, directly or indirectly, and shall not authorize any other person to (a) take any action to solicit or initiate any Company Takeover Proposal; (b) engage in negotiations with, or disclose any nonpublic information relating to the Company or any Company Subsidiary or afford access to the properties, books or records of the Company or any Company Subsidiary to, any Person that may be considering making, or has made, a Company Takeover Proposal or has agreed to endorse a Company Takeover Proposal; or (c) enter into any agreement relating to a Company Takeover Proposal. Such Shareholder will promptly notify Parent after receipt of a Company Takeover Proposal or any request for nonpublic information relating to the Company or any Company Subsidiary or for access to the properties, books or records of the Company or any Company Subsidiary by any Person that may be considering making, or has made, a Company Takeover Proposal and will keep Parent informed of the status and details of any such Company Takeover Proposal, indication or request.

Section 3.03. Dissenters’ Rights. The Shareholder hereby irrevocably waives (on behalf of itself and each of its Affiliates), any and all claims and/or causes of action (derivative or otherwise) and any rights of appraisal or rights to dissent from the Merger that Shareholder or any such Affiliate may have, either currently or in the future, against the Company or any of the Company’s former or current officers, directors, shareholders, affiliates, employees and agents (the “Company Persons”) resulting from, or arising in connection with, any act or omission by any Company Person directly in connection with the Merger Agreement or the consummation of the Merger, the negotiation of the terms thereof and/or the other agreements, documents and instruments to be executed in connection therewith.

Section 3.04. Confidential Information. During the term of this Agreement, the Shareholder will maintain the confidentiality of and will not use or disclose any confidential information of Parent, the Company or any of their respective subsidiaries obtained by the Shareholder or his, her or its affiliates while a shareholder of the Company or serving as a director, officer, or employee of the Company or any of its subsidiaries. For purposes of this Agreement, “confidential information” means any information and material of or relating to Parent or the Company or any of their respective subsidiaries, including proprietary information and trade secrets, and any and all information disclosed to or known by the Shareholder or its affiliates as a consequence of any such person’s employment, services or status as a director, officer, or employee of the Company or any of its subsidiaries, but does not include (a) information that is or becomes generally available to the public other than as a result of an unauthorized disclosure; (b) information that was in the Shareholder’s possession on a non-confidential basis prior to the Shareholder serving as a director, officer or employee of the Company or its subsidiaries, or information received by the Shareholder from another individual without any limitations on disclosure, but only if the Shareholder had no reason to believe that the other individual was prohibited from using or disclosing such information by a contractual or fiduciary obligation; or (c) information that was independently developed by the Shareholder without use of or reference to any confidential information of Parent, the Company or their respective subsidiaries. If the Shareholder is required by any governmental authority (by oral questions, interrogatories, requests for information or documents in legal proceedings, subpoena, civil investigative demand or other similar process), to disclose any confidential

4

information, the Shareholder will provide Parent with prompt notice of any such requirement and will provide, at Parent’s expense, such reasonable cooperation as Parent may request so that Parent may seek a protective order or other appropriate remedy. If, in the absence of a protective order or other remedy or the receipt of a written waiver from Parent, the Shareholder is nonetheless legally compelled to disclose confidential information to any governmental authority, the Shareholder may, without liability hereunder, disclose to such governmental authority only that portion of confidential information which is legally required to be disclosed; provided, that the Shareholder exercises reasonable efforts to preserve the confidentiality of such confidential information, including, without limitation, by reasonably cooperating with Parent, at its expense, to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded to such confidential information by such governmental authority. Nothing in this Agreement prohibits Shareholder from reporting possible violations of federal law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of applicable law or regulation. The Shareholder does not need the prior authorization of Parent to make any such reports or disclosures, and the Shareholder is not required to notify the Company that the Shareholder has made such reports or disclosures.

ARTICLE 4

Each Spouse agrees not to assert or enforce, and does hereby waive, any marital interest such Spouse may acquire with respect to the voting of the Shares by virtue of such Spouse’s marriage to a Shareholder, including without limitation any rights granted under any community property statute which would adversely affect any of the covenants made by a Shareholder pursuant to this Agreement; provided that such Spouse shall not be prohibited from asserting any rights such Spouse may have against the portion of the aggregate Per Share Merger Consideration received by a Shareholder in exchange for his or her Shares.
