(b) any shares of capital stock or voting securities of the Company that Stockholder becomes the beneficial owner of as a result of any change in Company Common Stock by reason of a stock dividend, stock split, split-up, recapitalization, reorganization, business combination, consolidation, exchange of shares, or any similar transaction or other change in the capital structure of the Company affecting the Company Common Stock.

2.1. (a) Stockholder is the beneficial owner of the Subject Shares set forth opposite his name on Exhibit A hereto; (b) the Subject Shares set forth opposite his name on Exhibit A hereto constitute Stockholder’s entire interest in the outstanding capital stock and voting securities of the Company as of the date

hereof; (c) the Subject Shares are, and will be, at all times up until the Expiration Date, free and clear of any liens, claims, options, charges, security interests, proxies, voting trusts, agreements, rights, understandings or arrangements, or exercise of any rights of a stockholder in respect of the Subject Shares or other encumbrances (except as to shares with respect to which Roger F. Hruby holds an irrevocable proxy, as noted on Exhibit A); (d) Stockholder has the power of disposition with respect to all of the Subject Shares set forth opposite his name on Exhibit A hereto outstanding on the date hereof and will have voting power and power of disposition with respect to all of the Subject Shares acquired by such Stockholder after the date hereof; and (e) Stockholder’s principal residence or place of business is accurately set forth on Exhibit A hereto.

2.2. Stockholder has full power and legal capacity to execute and deliver this Agreement and to comply with and perform Stockholder’s obligations hereunder. This Agreement has been duly and validly executed and delivered by Stockholder and constitutes the valid and binding obligation of Stockholder, enforceable against Stockholder in accordance with its terms. The execution and delivery of this Agreement by Stockholder does not, and the performance of Stockholder’s obligations hereunder will not, result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any right to terminate, amend, accelerate or cancel any right or obligation under, or result in the creation of any lien or encumbrance on any Subject Shares pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which Stockholder is a party or by which Stockholder or the Subject Shares are or will be bound or affected.

2.3. Stockholder hereby unconditionally and irrevocably instructs the Company not to, (a) permit the Transfer of his Subject Shares, in violation of this Agreement, on its books and records by Stockholder or (b) issue a new certificate representing any such Subject Shares.

2.4 Stockholder understands and acknowledges that Parent is entering into the Merger Agreement in reliance upon Stockholder’s execution, delivery and performance under this Agreement.

3. Termination. This Agreement and all obligations of Stockholder hereunder and shall terminate and shall have no further force or effect as of the Expiration Date; provided, however, that any such termination shall not relieve any party of any liability arising as a result of the breach of this Agreement by such party prior to such termination.

4. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

5. Binding Effect and Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any party without the prior written consent of the other party; provided, however, that Parent may, in its sole discretion, assign any or all of its rights, interests and obligations hereunder to any direct or indirect wholly-owned subsidiary of Parent. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

6. Amendment and Modification. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties.

7. Specific Performance; Injunctive Relief. The parties hereto acknowledge that Parent will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of Stockholder set forth herein. Therefore, it is agreed that, in addition to any other remedies that may be available to Parent upon any such violation, Parent shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to Parent at law or in equity and Stockholder hereby waives any and all defenses which could exist in his favor in connection with such enforcement and waives any requirement for the security or posting of any bond in connection with such enforcement.
