In the event of a stock dividend or stock distribution, or any change in the Company Stock by reason of any stock dividend or stock distribution, split-up, recapitalization, combination, exchange of shares or the like, the term “Stockholder Owned Shares” shall be deemed to refer to and include the Stockholder Owned Shares as well as all such stock dividends and stock distributions and any securities into which or for which any or all of the Stockholder Owned Shares may be changed or exchanged or which are received in such transaction.

     Section 3.3 Acquisition Proposals in Respect of Stockholder Owned Shares. (a) Each Stockholder shall, and each Stockholder shall cause each of its Representatives to, immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Third Party conducted prior to the date hereof with respect to any Acquisition Proposal. Each of the Stockholders shall not, nor in the case of clauses (i) and (ii) shall it permit any of its Affiliates to, nor shall it authorize or knowingly permit any Representative of, the Stockholders or in the case of clauses (i) and (ii) any of their Affiliates to, (i) solicit or initiate, or take any action to knowingly encourage, or knowingly facilitate or knowingly induce, directly or indirectly, any inquiries relating to, or the submission of, any Acquisition Proposal from any Third Party; (ii) participate in any discussions or negotiations regarding any Acquisition Proposal, or furnish to any Person any non-public information or data with respect to or access to the properties of the Company in connection with an Acquisition Proposal; or (iii) enter into any agreement, arrangement or understanding with respect to any Acquisition Proposal or enter into any agreement requiring it to abandon, terminate or fail to consummate the Merger and the transactions contemplated by this Agreement. Notwithstanding the foregoing sentence or any other provision of this Agreement, if, after the date hereof and prior to the receipt of stockholder approval of the Merger Agreement, the Stockholders receive or the Company receives a bona fide Acquisition Proposal by a Third Party and such Acquisition Proposal did not result, directly or indirectly, from a breach of this Section 3.3 or Section 7.2 of the Merger Agreement, which the Company Board or Committee determines in good faith (after consulting outside legal and financial advisors) that such Acquisition Proposal constitutes, or would reasonably be expected to lead to a Superior Acquisition Proposal, and the Company or the Stockholders receives from such Third Party an executed confidentiality agreement having provisions that are no less restrictive than those of the Confidentiality Agreement with respect to Parent (except with respect to any “standstill” provision or other provision having similar effect in the Confidentiality Agreement), then the Stockholders may, in response to such Acquisition Proposal, subject to compliance with this Section 3.3 and after giving notice to Parent (x) furnish information or data or access with respect to the Company and its Subsidiaries to, and (y) participate in discussions and negotiations directly or through their Representatives with, such Third Party; provided that the Stockholders shall provide or make available, to the extent not previously provided or made available to Parent or its representatives, to Parent any material non-public information with respect to the

Stockholders that is provided to the Third Party making such Acquisition Proposal prior to or substantially concurrently with the time it is provided or made available to such Third Party; provided further, however, that nothing in this Section 3.3 shall require the Stockholders to provide or make available to Parent information that (i) it is not legally permitted to disclose or the disclosure of which would contravene any applicable Law or binding order or (ii) the Company determines, in its good faith judgment, would constitute trade secrets or other material information that is competitively sensitive. Nothing contained in this Agreement shall prevent a Stockholder from making such disclosure that a Stockholder (after consultation with counsel) concludes in good faith is necessary in order to comply with its organizational documents, including without limitation its operating agreement or corresponding document, or to comply with its fiduciary duties to its stockholders or partners under applicable Law.

          (b) Each Stockholder shall advise Parent orally and in writing, promptly (but in no event later than 24 hours) after receipt thereof, of (i) any proposal for an Acquisition Proposal received by any Representative of any Stockholder, and (ii) the material terms of such Acquisition Proposal (including the identity of the entity proposing the Acquisition Proposal), and provide a copy of such proposal for an Acquisition Proposal to Parent if such proposal is in writing. Each Stockholder shall keep Parent reasonably informed on a reasonably current basis of the status of, and any material changes to, the terms of any such Acquisition Proposal and the status of discussions and negotiations with respect thereto of which it is aware. Performance by the Company of its obligations under Section 7.2 of the Merger Agreement shall be deemed performance by the Stockholders of the provisions of this Section 3.3(b) with respect to the same matter so long as any such activities by the Stockholders are consistent in all material respects with the discussions or activity underlying the required disclosure by the Company to Parent.

          (c) Each Stockholder agrees that it will promptly inform its Representatives and its Affiliates’ Representatives of the obligations undertaken in this Article III.

          (d) Notwithstanding any provision in this Agreement to the contrary, the Stockholders enter into the agreements and understandings herein solely in their capacity as the beneficial owners of the Stockholder Owned Shares, and nothing herein shall limit or effect any actions taken by any Representative of a Stockholder in such Representative’s capacity as a director of the Company or cause a Stockholder to become obligated to take or effect any action hereunder.

     Section 3.4 Certain Provisions.

          (a) Notwithstanding anything to the contrary in this Article III, (1) no provision of this Article III shall prohibit, limit or otherwise restrict a Representative of a Stockholder in his capacity as a director or officer of the Company, and (2) from and after a Board Recommendation Change made in compliance with the Merger Agreement in connection with a Superior Acquisition Proposal, Section 2.1(a) shall apply only with

respect to the Lock-Up Subject Shares and, for the avoidance of doubt, the Stockholders, in their sole discretion, shall be able to enter into any voting agreement, proxy, consent or power of attorney with respect to the remaining Stockholder Owned Shares. Notwithstanding anything to the contrary in this Agreement, the restrictions in this Article III shall terminate and be of no further force and effect upon the termination of this Agreement or the consummation of the Merger.

          (b) For the purposes of this Agreement, the Company shall be deemed not to be an Affiliate or Subsidiary of any one or more of the Stockholders, and any officer, director, employee, agent or advisor of the Company (in each case, in their capacities as such) shall be deemed not to be a Representative of a Stockholder.

          “Permitted Transferee” means (i) any Person other than a Person who is known to the Stockholder to be an Openly Hostile Transferee, (ii) subject to compliance by the Stockholders with Section 4.2(c) hereof, any Person who shall have commenced a tender offer pursuant to Rule 14e under the Exchange Act for shares of Parent, (iii) any stockholder or partner of such Stockholder, or (iv) any Pre-Approved Purchaser.

     Section 8.9 Entire Agreement; Assignment. This Agreement constitutes the entire agreement of the parties and supersedes all prior agreements and understandings, both written and oral, among the parties hereto, or any of them, with respect to the subject matter hereof. Except as provided in Section 4.2(c), this Agreement may not be assigned by any of the parties hereto by operation of law or otherwise.

     Section 8.10 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and assigns. Nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement.

     Section 8.11 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of 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 a manner 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 the transactions contemplated hereby are fulfilled to the fullest extent possible.

     Section 8.12 Certain Interpretations. For purposes of this Agreement:

          (a) Unless otherwise specified, all references in this Agreement to Articles and Sections shall be deemed to refer to Articles and Sections of this Agreement.

          (b) The Article and Section captions herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof.

          (c) Unless the context otherwise requires, words describing the singular number shall include the plural and vice versa, and words denoting any gender shall include all genders.

          (d) The words “include,” includes” and “including,” when used herein shall be deemed in each case to be followed by the words “without limitation.”

          (e) The parties hereto agree that they have been represented by legal counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any Law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document shall be construed against the party drafting such agreement or document.

     Section 8.13 Fees and Expenses. Except as otherwise provided herein, whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses.

     Section 8.14 Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to any Subject Shares. All rights, ownership and economic benefits of and relating to the Subject Shares shall remain vested in and belong to the Stockholders, and Parent shall have no authority to direct the Stockholders in the voting or disposition of any of the Stockholder Owned Shares, except as otherwise provided herein, or Parent Subject Shares.

     Section 8.15 Capacity as a Stockholder. The Stockholders do not make any agreement or understanding herein in their capacity as being associated with a director of the Company. The Stockholders make their agreements and understandings herein solely

in their capacities as the record holder and beneficial owner of the Subject Shares and, notwithstanding anything to the contrary herein, nothing herein shall limit or affect any actions taken by a Representative of a Stockholder in his capacity as a director or officer of the Company.

     IN WITNESS WHEREOF, Parent and each Stockholder has caused this Agreement to be duly executed as of the day and year first above written.
