ARTICLE IV.

COVENANTS OF THE STOCKHOLDER

The Stockholder hereby covenants and agrees as follows:

Section 4.1 No Transfer.

(a) Other than pursuant to the terms of this Agreement or the Merger Agreement, without the prior written consent of Parent or as otherwise provided in this Agreement, during the term of this Agreement, the Stockholder hereby agrees to not, directly or indirectly, (i) grant any proxies, options, rights of first offer or refusal or power of attorney or enter into any voting trust or other agreement or arrangement with respect to, or restricting the voting of, any Covered Shares, (ii) enter into a swap or any other agreement or any transaction that transfers, in whole or in part, the economic consequence of ownership of any Covered Shares or (iii) sell, pledge, assign, transfer, tender, exchange, offer, encumber or otherwise dispose of (including by merger or consolidation), or enter into any contract, option or other arrangement or understanding with respect to the direct or indirect assignment, transfer, tender, exchange, offer, encumbrance or other disposition of (including by merger or consolidation) (each, a “Transfer”), any Covered Shares. Any action taken or attempted to be taken in violation of the preceding sentence will be null and void. The Stockholder further agrees to authorize and request Parent and the Company to notify the Company’s transfer agent that there is a stop transfer order consistent herewith with respect to the Covered Shares and that this Agreement places limits on the voting of the Covered Shares. Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, the Stockholder may Transfer any or all of the Covered Shares (i) by will, or by operation of law, in which case this Agreement shall, to the extent permitted by Law, bind the transferee, or (ii) to affiliates, trusts and charitable organizations, so long as the transferee, prior to such Transfer executes a counterpart of this Agreement (with such modifications as Parent may reasonably request solely to reflect such Transfer) and agrees to be bound by its terms.

(b) The Stockholder hereby covenants and agrees that for a period of 90 days following the Effective Time (the “Lock-Up Period”), such Stockholder shall not Transfer or consent to any Transfer of, any shares of Parent Common Stock received by such Stockholder in the Merger with respect to the Covered Shares, or any interest therein, or enter into any contract, option or other arrangement or understanding with respect to the direct or indirect Transfer of, any shares of Parent Common Stock received by such Stockholder in the Merger with respect to the Covered Shares or any interest therein to any Person (other than Parent); provided, however, that the Stockholder may participate during the Lock-Up Period with respect to its shares of Parent Common Stock in any merger, tender offer or other business combination or other transaction, in each case, which the Board of Directors of Parent has recommended to Parent’s stockholders; provided, further, that after the Effective Time and during the Lock-Up Period, the Stockholder may Transfer any or all of the shares of Parent Common Stock received by such Stockholder in the Merger with respect to the Covered Shares (i) by will, or by operation of law, in which case this Section 4.1(b) shall, to the extent permitted by Law, bind the transferee until the expiration of the Lock-Up Period, or (ii) to affiliates, trusts and charitable organizations, so long as the transferee, prior to such Transfer executes a counterpart of this Agreement (with such modifications as Parent may reasonably request solely to reflect such Transfer) and agrees to be bound by its terms (including this Section 4.1(b)). The Stockholder hereby agrees that, in order to ensure compliance with the restrictions referred to herein, Parent may issue appropriate stop transfer instructions to its transfer agent in respect of the Stockholder’s Parent Common Stock. Parent agrees that it will cause any stop transfer instructions imposed pursuant to this Section 4.1(b) to be lifted, and any legended certificates of Parent Common Stock delivered to the Stockholder pursuant to the Merger Agreement to be replaced with certificates not bearing such legend, promptly following the termination of the Lock-Up Period. The restrictions on transfer provided in this Section 4.1(b) shall be in addition to any restrictions on transfer of the Parent Common Stock imposed by any applicable Laws.

Section 4.2 Public Announcement. The Stockholder shall consult with Parent before issuing any press releases or otherwise making any public statements with respect to the transactions contemplated herein, in such Stockholder’s capacity as a stockholder of the Company, except as may be required by applicable Law. The Stockholder hereby consents to disclosure in the Registration Statement and the Proxy Statement (including all documents and schedules filed with the SEC) and press releases with respect to the Merger in accordance with the Merger Agreement, of the identity of the Stockholder and ownership of the Covered Shares and the nature of such Stockholder’s commitments, arrangements and understandings pursuant to this Agreement.

Section 4.3 Additional Shares. The Stockholder shall promptly notify Parent of the number of any new Covered Shares acquired by the Stockholder, if any, after the date hereof. Any such shares shall be automatically subject to the terms of this Agreement as though owned by the Stockholder on the date hereof.

Section 4.4 No Restraint on Officer or Director Action; Etc. Notwithstanding anything to the contrary herein, Parent hereby acknowledges and agrees that no provision in this Agreement shall limit or otherwise restrict the Stockholder with respect to any act or omission that the Stockholder may undertake or authorize in such Stockholder’s capacity as a director or officer of the Company or any subsidiary thereof, including any vote that such individual may make as a director of the Company with respect to any matter presented to the Company’s board of directors. The Stockholder has executed this Agreement solely in such Stockholder’s capacity as the record and/or beneficial owner of the Covered Shares and no action taken by the Stockholder in such Stockholder’s capacity as a director or officer of the Company or any subsidiary thereof shall be deemed to constitute a breach of any provision of this Agreement.
