NOW, THEREFORE, in consideration of the premises and of the representations, warranties, covenants and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

(b) “Person” shall mean any individual, corporation, partnership, limited partnership, joint venture, association, trust, unincorporated organization, limited liability company or other entity.

Notwithstanding the foregoing, a Stockholder may decline to tender, or may withdraw, any and all of Stockholder’s Shares if, without the consent of Stockholder, Purchaser amends the Offer to (i) reduce the Offer Price for the Shares in the Offer, (ii) reduce the number of shares of Company Common Stock subject to the Offer, (iii) change the form of consideration payable in the Offer, (iv) change the “Minimum Condition,” which requires the tender of 35% of the fully diluted shares of Company Common Stock, or (v) amend or modify any term or condition of the Offer in a manner adverse to Stockholder (other than insignificant changes or amendments or other than to waive any condition other than the Minimum Condition which the parties agree cannot be waived or reduced) (clauses (i) through (v) collectively are hereinafter referred to as a “Material Amendment”). A Stockholder shall give Purchaser at least two (2) business days’ prior notice of any withdrawal of its Shares pursuant to the immediately preceding proviso.

(b) Stockholder hereby acknowledges and agrees that the obligation of Purchaser to accept for payment and pay for any Shares in the Offer, including the Shares Beneficially Owned by Stockholder, shall be subject to the terms and conditions of the Offer.

(c) Purchaser shall return to Stockholder all materials tendered by Stockholder to Purchaser promptly after the termination or expiration of the Offer without Purchaser purchasing such Shares of Company Common Stock tendered pursuant to the Offer in accordance with its terms.

(d) Stockholder hereby agrees to permit Purchaser to publish and disclose in the Offer documents (including all related documents and schedules filed with the SEC), its identity and ownership of Company Common Stock and the nature of its obligations, commitments, arrangements and understandings under this Agreement.

The Company shall ensure that its officers, directors and key employees and its investment bankers, attorneys and other representatives are aware of the provisions of this Section 5.5(a).

(b) Notwithstanding the provisions of Section 5.5(a), at any time prior to the Effective Time, the Company Board (or the applicable committee thereof) may (i) withdraw (or amend or modify in a manner adverse to Purchaser), or publicly propose to withdraw (or amend or modify in a manner adverse to Purchaser), the recommendation or declaration of advisability by the Company Board of this Agreement, the Offer or the other Transactions, (ii) recommend, or publicly propose to recommend, any Takeover Proposal, or (iii) to the extent permitted pursuant to and in compliance with Section 7.1(e)(i), authorize and allow the Company to enter into a binding written agreement concerning a transaction that constitutes a Superior Proposal; provided that the Company Board (or the applicable committee thereof) determines in good faith (after receiving the advice of its outside counsel) that the failure to take such action would create a material risk of a breach by the Company Board of its fiduciary duties to the Company’s stockholders under applicable Law.

(c) Nothing contained in this Section 5.5 shall prohibit the Company or the Company Board from (i) taking and disclosing to the holders of Company Common Stock a position with respect to a tender or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or (ii) from making any disclosure to the holders of Company Common Stock, if in the good faith judgment of the Company Board (after consultation with outside counsel), failure to do so would be inconsistent with its obligations under applicable Law (including the Company Board’s duties of good faith and candor to the holders of Company Common Stock); provided that the Company Board shall not recommend that the stockholders of the Company tender their Company Common Stock in connection with any such tender or exchange offer unless the Company Board determines in good faith that such Takeover Proposal constitutes a Superior Proposal.

(d) For purposes of this Agreement:

(i) “Takeover Proposal” shall mean any bona fide proposal or offer (and not withdrawn) from any Person (other than Purchaser or any of its Affiliates) relating to any acquisition, merger, consolidation, reorganization, share exchange, recapitalization, liquidation, direct or indirect business combination, asset acquisition or other similar transaction involving the Company or any Company Subsidiary of (A) the assets or businesses that constitute or represent 20% or more of the total revenue, operating income, or fair market value of the assets of the Company and its Subsidiaries, taken as a whole, or (B) 20% or more of the outstanding shares of Company Common Stock, in each case other than the Transactions.

(ii) “Superior Proposal” means any bona fide written offer (which is not withdrawn) in respect of (i) any transaction as a result of which the holders of Company Common Stock cease to own at least 45% of the Company Common Stock on a Fully Diluted Basis (subject to reduction as provided for in Section 1.3) of the ultimate parent entity resulting from such transaction or sale of all or substantially all of the assets of the Company, or (ii) a merger, consolidation, reorganization, share exchange, recapitalization, liquidation, direct or indirect business combination, or other similar transaction involving the acquisition of at least 35% of the outstanding Company Common Stock on a Fully Diluted Basis (subject to reduction as provided for in Section 1.3), that in any such case provides for consideration to the holders of Company Common Stock consisting of cash, securities or both cash and securities (it being understood that securities retained by the holders of Company Common Stock be included for purposes of this determination), and is on terms that the Company Board determines in its good faith judgment (after receipt of the advice of its outside counsel), taking into account all relevant factors, including the price, form of consideration, closing conditions, legal and regulatory requirements, the ability to finance the proposal, anticipated timing of and prospects for consummating the transaction contemplated by the proposal, the identity of the party making the proposal and other aspects of the proposal that the Company Board deems relevant, (A) would, if consummated, result in a transaction that is more favorable to the holders of Company Common Stock from a financial point of view than the Transactions (including the terms of any proposal by Purchaser to modify the terms of the Transactions) and (B) is reasonably capable of being completed on the terms proposed.

(e) In addition to the other obligations of the Company set forth in this Section 5.5, the Company shall (i) promptly notify Purchaser orally and in writing of any request for information with respect to any Takeover Proposal, or any inquiry with respect to or which could reasonably be expected to result in a Takeover Proposal, the material terms and conditions of such request, Takeover Proposal or inquiry, and the identity of the Person making the same; (ii) contemporaneously with furnishing any non-public information concerning the Company’s business, present or future performance, financial condition or results of operations, to any third party with respect to any Takeover Proposal, furnish or make available such information to Purchaser to the extent such information has not been previously provided to Purchaser, (iii) provide to Purchaser three business days’ written notice prior to (A) withholding, withdrawing, amending or modifying in a manner adverse to Purchaser, or publicly proposing to withhold, withdraw, amend or modify in a manner adverse to Purchaser the Company recommendations referred to in Section 2.3(b) or (B) entering into a binding written agreement concerning a transaction that constitutes a Superior Proposal as set forth in Section 5.5(b), advising Purchaser that the Company Board intends to take such action and specifying the reasons therefor, including the material terms and conditions of any Superior Proposal that is the basis of the proposed action by the Company Board and the identity of the Person making the proposal; and (iv) if Purchaser shall make a counterproposal following delivery of written notice of a Takeover Proposal or Superior Proposal, consider and cause its legal advisors to consider in good faith the terms of such counterproposal.
