The Stockholder has all requisite power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. The Stockholder has duly authorized, executed and delivered this Agreement, and this Agreement constitutes the legal, valid and binding obligation of the Stockholder, enforceable against the Stockholder in accordance with its terms, except as such enforceability may be limited by (a) bankruptcy, insolvency, reorganization, moratorium or similar laws of general applicability affecting the enforcement of creditors’ rights and (b) the application of general principles of equity, whether such enforceability is considered in a proceeding in equity in law. The execution and delivery by the Stockholder of this Agreement does not, and the consummation of the transactions contemplated hereby and compliance with the terms hereof will not, conflict with, or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation or to loss of a material benefit under, or to increased, additional, accelerated or guaranteed rights or entitlements of any person

under, or result in the creation of any lien upon any of the properties or assets of the Stockholder under (i) any provision of any contract, lease, license, indenture, agreement, note, bond, permit, license, concession, franchise or other instrument (“Contract”) to which the Stockholder is a party or by which any properties or assets of the Stockholder are bound; or (ii) subject to the filings and other matters referred to in the next sentence, any provision of any order, judgment or Law applicable to the Stockholder or the properties or assets of the Stockholder.

If the Stockholder is married and the Subject Shares of the Stockholder constitute community property this Agreement constitutes a valid and binding agreement of the Stockholder’s spouse, enforceable against such spouse in accordance with its terms. No trust of which the Stockholder is a trustee requires the consent of any beneficiary to the execution and delivery of this Agreement or to the consummation of the transactions contemplated hereby. The Stockholder hereby acknowledges that it has received and reviewed a copy of the Merger Agreement.

(b) The Subject Shares. The Stockholder is the owner of, and, except for any Subject Shares held in “street name” and identified on Schedule A, the record owner of the Subject Shares set forth on Schedule A attached hereto.

- 2 -

enforceability is considered in a proceeding in equity or at law. The execution and delivery by Parent of this Agreement do not, and the consummation of the transactions contemplated hereby and compliance with the terms hereof will not, conflict with, or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation or to loss of a material benefit under, or result in the creation of any lien upon any of the properties or assets of Parent under (i) the certificate of incorporation or bylaws of Parent, (ii) any provision of any Contract to which Parent is a party or by which any properties or assets of Parent are bound or (iii) subject to the reports under Sections 13(d) and 16 of the Exchange Act as may be required in connection with this Agreement and the transactions contemplated hereby, any provision of any Judgment or Law applicable to Parent or the properties or assets of Parent.

- 5 -

his status as a stockholder of the Company or any agreement or instrument with the Company pertaining to the Subject Shares and the Subject Options or Stockholder’s status as a stockholder of the Company, in any case other than as set forth in the Merger Agreement or the Exchange Agreement.

SECTION 6. Additional Matters.

(a) Stockholder shall, from time to time, execute and deliver, or cause to be executed and delivered, such additional or further consents, documents and other instruments as Parent may reasonably request, for the purpose of effectively carrying out the transactions contemplated by this Agreement. Without limiting the generality or effect of the foregoing or any other obligation of Stockholder hereunder, Stockholder hereby authorizes Parent to deliver a copy of this Agreement to the Company and hereby agrees that each of the Company and Parent may rely upon such delivery as conclusively evidencing the waivers of Stockholder referred to in Section 5.

(b) No person executing this Agreement who is or becomes during the term hereof a director or officer of the Company makes any agreement or understanding herein in his or her capacity as a director or officer of the Company. Stockholder is entering into this Agreement solely in his, her or its capacity as the record holder and beneficial owner of the Subject Shares and nothing herein shall limit or affect any actions taken by Stockholder in his or her capacity as an officer or director of the Company to the extent specifically permitted by the Merger Agreement.

(c) The Stockholder agrees that this Agreement and the obligations hereunder shall attach to the Subject Shares and shall be binding upon any person or entity to which legal or beneficial ownership of such Subject Shares shall pass, whether by operation of law or otherwise, including the Stockholder’s successors.

- 6 -

(c) Interpretation. When a reference is made in this Agreement to Sections, such reference shall be to a Section to this Agreement unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Wherever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”.

(d) Severability. If any provision of this Agreement is held to be invalid or unenforceable for any reason, it shall be adjusted rather than voided, if possible, in order to achieve the intent of the parties hereto to the maximum extent possible. In any event, the invalidity or unenforceability of any provision of this Agreement in any jurisdiction shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of this Agreement, including that provision, in any other jurisdiction.

(e) Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement. This Agreement shall become effective when signed by both Parent and Stockholder and delivered to each of them. Each party need not sign the same counterpart. Any counterpart may be executed by facsimile signature and such facsimile signature shall be deemed an original.

(f) Entire Agreement; No Third-Party Beneficiaries. This Agreement, the Exchange Agreement and the Merger Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. This Agreement is not intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

(g) Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof.

(h) 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 Parent without the prior written consent of Stockholder or by Stockholder without the prior written consent of Parent, and any purported assignment without such consent shall be void; provided that notwithstanding the foregoing Parent may assign or transfer its rights, interests and obligations under this Agreement to any Person to which Parent assigns or transfers its rights, interests and obligation under the Merger Agreement in accordance with the Merger Agreement. 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.

- 7 -

(i) Remedies. No failure or delay by any party in exercising any right, power or privilege under this Agreement shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies provided herein shall be cumulative and not exclusive of any rights or remedies provided by law or in equity. Parent shall be entitled to recover its reasonable attorney’s fees and expenses in enforcing its rights under this Agreement.

(j) Waiver of Jury Trial. EACH OF THE PARTIES AGREES AND ACKNOWLEDGES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELOCATING TO THIS AGREEMENT, OR THE BREACH, TERMINATION OR VALIDITY OF THIS AGREEMENT.

(k) Specific Performance. Stockholder acknowledges and agrees that (a) the covenants, obligations and agreements of Stockholder contained in this Agreement relate to special, unique and extraordinary matters, (b) Parent is and will be relying on such covenants in connection with entering into the Merger Agreement and the performance of its obligations under the Merger Agreement and (c) a violation of any of the terms of such covenants, obligations or agreements will cause Parent irreparable injury for which adequate remedies are not available at law. Therefore, Stockholder agrees that Parent shall be entitled to an injunction, restraining order or such other equitable relief (without the requirement to post bond) as a court of competent jurisdiction may deem necessary or appropriate to restrain Stockholder from committing any violation of such covenants, obligations or agreements. These injunctive remedies are cumulative and in addition to any other rights and remedies Parent may have.

IN WITNESS WHEREOF, each party has duly executed this Agreement, all as of the date first written above.
