2. Section 4.2 is amended and restated as follows:

4.2 No Solicitation of Transactions.

(a) During the period beginning on the Financing Contingency Release Date to the Effective Time the Company shall not, nor shall it permit any of its Subsidiaries to, nor shall it authorize or permit any officer, director or employee of, or any investment banker, attorney or other advisor or representative of, the Company or any of its Subsidiaries to (i) solicit, accept or initiate, encourage, or facilitate, directly or indirectly, any inquiries relating to, or the submission of, any proposal or offer, whether in writing or otherwise, from any Person other than Eastern, Newco or any Affiliates thereof (any such other Person, a “Third Party”) to acquire beneficial ownership (as defined under Rule 13(d) of the Exchange Act) of all or more than fifteen percent (15%) of the assets of the Company and its Subsidiaries, taken as a whole, or fifteen percent (15%) or more of any class or series of equity securities of the Company, whether pursuant to a merger,

consolidation or other business combination or other transaction, sale of shares of stock, sale of assets, tender offer, exchange offer or similar transaction or series of related transactions, which is structured to permit such Third Party to acquire beneficial ownership of more than fifteen percent (15%) of the assets of the Company and its Subsidiaries, taken as a whole, or fifteen percent (15%) or more of any class or series of equity securities of the Company (any transaction or series of transactions with the foregoing effect, a “Competing Transaction”); (ii) participate or engage in any discussions or negotiations with any Third Party regarding any Competing Transaction, or furnish to any Third Party any information or data with respect to or access to the properties of the Company in connection with a Competing Transaction, or take any other action to facilitate the making of any proposal that constitutes, or may reasonably be expected to lead to, any Competing Transaction; (iii) withdraw, modify or amend in any way adverse to Eastern or Newco its recommendation to the Company’s stockholders that they approve this Agreement and the Merger, except in strict compliance with this Section 4.2, or (iv) enter into any agreement with respect to any Competing Transaction, approve or recommend or resolve to approve or recommend any Competing Transaction, or enter into any agreement requiring it to abandon, terminate or fail to consummate the Merger or the other transactions contemplated by this Agreement.

(b) Notwithstanding the foregoing sentence or anything to the contrary in this Agreement, if during the period beginning on the Financing Contingency Release Date to the Effective Time, the Company receives (in the absence of any violation of this Section 4.2) a bonafide, unsolicited written proposal or offer for a Competing Transaction prior to the receipt of the Company Shareholder Approval and that has not been withdrawn, which the Board of Directors, acting reasonably and in good faith (after consultation with the Company’s outside legal counsel and financial advisor), determines by majority vote (excluding any members of the Board of Directors that are not independent of the Third Parties making such offer for a Competing Transaction) is superior to the terms of this Agreement based upon the financial terms of the proposed Competing Transaction, the proposed timing of the Competing Transaction or the likelihood that such Competing Transaction will be consummated (a “Superior Competing Transaction”), then the Company may, in response to such unsolicited proposal or offer and subject to compliance with this Section 4.2, furnish information with respect to the Company and its Subsidiaries to, and participate in discussions and negotiations directly or through its representatives with, such Third Party. Notwithstanding the foregoing, during the period beginning on the Financing Contingency Release Date to the Effective Time, the Company shall not provide any non-public information to any such Third Party unless the Company provides such non-public information pursuant to a nondisclosure agreement at least as restrictive as the Confidentiality Agreement (defined below). Nothing contained in this Agreement shall prevent the Board of Directors from (i) complying with any applicable Law, rule or regulation, including, without limitation, Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act, (ii) making any disclosure to the Company’s shareholders required by applicable Law, rule or regulation, or (iii) otherwise making such disclosure to the Company’s shareholders or otherwise that the Board of Directors (after consultation with its counsel) concludes in good faith is necessary in order to comply with its fiduciary duties to the Company’s shareholders under applicable Law.
