(“Chapter 44 Rights”).

AGREEMENT

NOW, THEREFORE, in contemplation of the foregoing and in consideration of the mutual agreements, covenants, representations and warranties contained herein and intending to be legally bound hereby, the Shareholder (jointly and severally, if more than one) agrees with Milestone and Newco as follows:

1. Transfer and Encumbrance. The Shareholder agrees that the Shareholder will not take, or permit to be taken, any action prior to the Expiration Date (as defined below) to, directly or indirectly: (a) transfer, sell, assign, give, grant, pledge, exchange or otherwise dispose of or encumber the Securities (except as may be specifically required by final, non-appealable court order, in which case the Shareholder shall give Milestone prior written notice and any such transferee shall be required, as a condition to such transfer, to agree to be bound by the terms and conditions of this Agreement), or to make any offer or agreement relating thereto; (b) deposit any of the Securities into a voting trust or enter into a voting agreement or arrangement with respect to such Securities, or grant any proxy or power of attorney with respect thereto, in each case, in a manner that conflicts, or could reasonably be expected to conflict, with the Shareholder’s obligations hereunder; or (c) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect sale, assignment, transfer, exchange or other disposition or transfer of any interest in, or the voting of, any of the Securities, in each case, in a manner that conflicts, or could reasonably be expected to conflict, with the Shareholder’s obligations hereunder. As used herein, the term “Expiration Date” shall mean the date on which the Merger Agreement is terminated in accordance with its terms.

2. Agreement to Vote and Not to Exercise Chapter 44 Rights. Prior to the Expiration Date, at every meeting of the Shareholders called with respect to any of the following, and at every adjournment thereof, and on every action or approval by written consent of the Shareholders with respect to any of the following, the Shareholder agrees to vote (or cause to be voted) the Common Shares owned of record directly by such Shareholder, and, to the fullest extent legally permitted, to cause holders of record of other Common Shares over which the Shareholder has the sole or shared power to vote (or to direct the vote) to vote (and to provide evidence thereof within ten (10) days prior to any such meeting) (such directly owned and other Common Shares being referred to herein collectively as the “Shares”) the Shares as follows: (a) in favor of approval of the Transaction, the Merger Agreement, the Merger Certificate and the transactions contemplated, respectively, thereby; (b) if required under Applicable Law, in favor of any alternative structure contemplated by the Merger Agreement; and (c) against the consummation of any proposal with respect to the acquisition of control of the Company by any Person other than Milestone or its Affiliates, or any action, proposal, agreement or transaction (other than the Transaction, the Merger Agreement or the transactions contemplated, respectively, thereby) that in any such case could reasonably be expected to result in a breach of any covenant, representation or warranty, or any other obligation or agreement, of the Company under the Merger Agreement, which could reasonably be expected to result in any of the conditions to the Company’s obligations under the Merger Agreement not being fulfilled, or which would be inconsistent with the Transaction or any other transaction contemplated by the Merger Agreement. Further, Shareholder shall cause all of such Shares not to become the subject of any communication to the Company that might reasonably be construed as asserting an intention by the Shareholder to exercise Chapter 44 Rights, or a claim of such Chapter 44 Rights, in respect of any such Shares. Prior to the Expiration Date, the Shareholder will not enter into any agreement or understanding with any Person to vote such Shares in a manner inconsistent with this Agreement or to exercise Chapter 44 Rights. This Agreement is intended to bind the Shareholder as a shareholder of the Company only with respect to the specific matters

2

set forth herein. Notwithstanding the foregoing, nothing in this Agreement shall limit or restrict the Shareholder from voting in his, her or its sole discretion on any matter other than those matters referred to in this Agreement.

3. No Opposition; Exclusivity.

3.1 Prior to the Expiration Date, the Shareholder agrees not to take, or cause to be taken, any action in the Shareholder’s capacity as a holder of Securities of the Company that would, or would be reasonably likely to, have the purpose or effect of preventing the consummation of the Transaction and the transactions contemplated by the Merger Agreement. Prior to the Expiration Date, the Shareholder agrees to take, or cause to be taken in its capacity as a holder of Securities of the Company, all actions necessary to execute and deliver a Letter of Transmittal and an Election.

3.2 From the date of this Agreement until the Closing Date, the Shareholder shall not, nor shall the Shareholder permit or cause any of its Affiliates, Family Members or representatives to, directly or indirectly: (a) solicit, initiate, seek, encourage or support any inquiries, proposals or offers from any Person (other than Milestone or its Affiliates) relating to, (b) furnish any non-public information to any Person (other than Milestone) relating to, (c) facilitate any inquiries or the making of any proposal which constitutes or may reasonably be expected to lead to, or (d) engage in any discussion or negotiations with or consider the merits of, or accept any unsolicited inquiries or proposals from any Person (other than Milestone) relating to, any transaction involving the sale of all or a substantial portion of the assets of the Company or all or a substantial portion of the Company’s capital stock (including, without limitation, the Shares), whether through a stock sale, merger, consolidation, reorganization, recapitalization, share exchange, business combination or similar transaction involving the Company or the Shareholder (each such transaction referred to herein as a “Proposed Acquisition Transaction”). The Shareholder shall promptly (but in any event within two (2) Business Days) notify Milestone of any Proposed Acquisition Transaction (which notice shall include the identity of the Person making the proposal, the beneficial owner(s) thereof, if any, the material terms of such proposal and, to the extent such proposal is made in writing, a copy of such proposal).

4. New Securities. The Shareholder hereby agrees that any shares of the capital stock or other securities of the Company that the Shareholder purchases, or with respect to which the Shareholder otherwise acquires a right to acquire or other beneficial ownership, after the date of this Agreement and prior to the Expiration Date (the “New Securities”), and any and all other shares or securities of the Company issued, issuable, exchanged or exchangeable in respect of any New Securities, shall become subject to the terms and conditions of this Agreement to the same extent as if they constituted Securities.

5.3 No Violation. Neither the execution, delivery and performance of this Agreement nor the consummation of the transactions contemplated hereby or by the Merger Agreement or any of the other Transaction Documents will (a) violate, or cause a breach of or default (or an event which with notice or the lapse of time or both would become a default) under, any contract, agreement or understanding, or any judgment, order or arbitration award, that is binding upon the Shareholder; or (b) cause the acceleration of any obligation under or give to any other Person any right of termination, amendment, acceleration or cancellation of, or result in the creation of an option or purchase right in favor of any Person, or any Lien on any property or asset of the Shareholder pursuant to any provision of any indenture, mortgage, lien, lease, agreement, contract, instrument, order, judgment, ordinance, regulation or decree to which the Shareholder is subject or by which the Shareholder or any of the Shareholder’s properties or assets are bound. No proceedings are pending which, if adversely determined, would have an adverse effect on any ability of the Shareholder to vote or dispose of any of the Securities.

5.4 Public Disclosure. The Shareholder agrees not to make any public disclosure or announcement of or pertaining to this Agreement, the Transaction, the Merger Agreement or the transactions contemplated, respectively, thereby, nor to disclose that any discussions or negotiations are taking place in connection therewith without the prior written consent of both Milestone and the Company; provided, however, that the Shareholder may make such disclosures if and to the extent that such are required, in the written opinion of counsel for the Shareholder, by Applicable Law, subject to prior consultation by the Shareholder or the Shareholder’s counsel concerning the proposed disclosure and the legal reasons therefor with counsel for Milestone and the Company.
