TRANSFER AND VOTING OF SHARES
AND OTHER COVENANTS OF THE STOCKHOLDERS

Section 2.01 Voting of Shares. From the date hereof until the termination of this Agreement in accordance with Section 5.01 hereof (the "Term"), at any annual, special or other meeting of the stockholders of Parent (or adjournment or postponement thereof) however called, and in any action by

consent of the stockholders of Parent, the Stockholder shall vote (or cause to be voted) its Shares or execute and deliver a consent of the stockholders of Parent (i) in favor of the adoption and approval of the Parent charter amendment and the Parent share issuance contemplated by the Merger Agreement, and any other actions in furtherance thereof requiring a vote of the stockholders of Parent, (ii) against any Parent Acquisition Proposal or Parent Superior Proposal, (iii) except for transactions contemplated by the Merger Agreement, against any proposal, action, transaction or agreement that would result in a breach in any material respect of any covenant, representation or warranty or any other obligation or agreement of Parent or Merger Sub under the Merger Agreement or which is reasonably likely to result in any of the conditions of Parent's or Merger Sub's obligations under the Merger Agreement not being fulfilled, (iv) except for transactions contemplated by the Merger Agreement, against any other action which could reasonably be expected to prevent, impede, interfere with or adversely affect the transactions contemplated by the Merger Agreement or the likelihood of such transactions being consummated and (v) in favor of any other matter necessary for consummation of the transactions contemplated by the Merger Agreement and in connection therewith to execute any documents which are necessary or appropriate in order to effectuate the foregoing; provided, however, that notwithstanding anything to the contrary herein, (i) in the event that the vote of the Shares is required in order to effect an amendment of the Merger Agreement, the provisions of this Agreement, including this Section 2.01, shall not apply with respect to any Stockholder's vote of such Shares and (ii) the provisions of this Agreement, including this Section 2.01, shall not apply at any time after the Board of Directors of Parent has, in accordance with the terms of the Merger Agreement, withdrawn its recommendation in favor of the adoption and approval of the Parent charter amendment and the Parent share issuance contemplated by the Merger Agreement. Any such vote shall be cast or consent shall be given in accordance with the applicable procedures relating thereto. The Stockholder agrees that it shall not enter into any agreement with any Person during the Term of this Agreement the effect of which would be inconsistent with or violative of this Section 2.01.

Section 2.02 No Inconsistent Arrangements. Except as contemplated by this Agreement and the Merger Agreement, the Stockholder shall not during the Term (i) transfer (which term shall include, without limitation, any sale, assignment, gift, pledge, hypothecation or other disposition), or consent to any transfer of, any or all of such Stockholder's Shares or any interest therein, or create or permit to exist any Encumbrance (as defined below) on such Shares, except in each such case to a party or parties that expressly consent to be bound by all of the terms of this Agreement, (ii) enter into any contract, option or other agreement or understanding with respect to, or consent to, any transfer of any or all of such Shares or any interest therein except with a party or parties that expressly consent to be bound by all of the terms of this Agreement, (iii) grant any proxy, power-of-attorney or other similar authorization in or with respect to such Shares, (iv) deposit such Shares into a voting trust or enter into a voting agreement or arrangement with respect to such Shares or any interest therein or (v) take any other action that would have the effect of materially interfering with the performance of its obligations hereunder or the transactions contemplated hereby or by the Merger Agreement.

Section 2.03 Irrevocable Proxy. The Stockholder hereby revokes any and all prior proxies or powers of attorney in respect of any of the Stockholder's Shares and constitutes and appoints the Company, or any nominee of the Company, with full power of substitution and resubstitution, at any time during the Term, as its proxy (its "Proxy"), for and in its name, place and stead, to vote each of its Shares as its Proxy, at every annual, special, adjourned or postponed meeting of the stockholders of Parent or to act by written consent in respect thereof, including the right to sign its name (as stockholder) to any consent, certificate or other document relating to Parent and any matter referred to in Section 2.01 above that Delaware law may permit or require. This proxy is given to secure the performance of the Stockholder's obligations under this Agreement. The Stockholder acknowledges that THIS PROXY (a) constitutes, among other things, an inducement for the Company to enter into the Merger Agreement, (b) IS COUPLED WITH AN INTEREST and (c) IS IRREVOCABLE AND SHALL NOT BE TERMINATED UPON THE OCCURRENCE OF ANY EVENT; provided, that this

proxy shall terminate at the end of the Term. The Stockholder hereby ratifies and confirms all that the Proxy may lawfully do or cause to be done by virtue hereof. The proxy granted herein by the Stockholder is executed and intended to be irrevocable in accordance with the provisions of Section 212(e) of the DGCL. The Stockholder hereby agrees that it shall not, during the Term of this Agreement, appoint or grant any subsequent proxy (and if appointed or granted in violation hereof, any such proxy shall not be effective). The Stockholder shall promptly cause a copy of this Agreement to be deposited with Parent at its principal place of business. The Stockholder shall take such further action or execute such other instruments as may be reasonably requested to effectuate the intent of this Section 2.03.

Section 2.04 Stockholder Capacity; Fiduciary Duties. No Stockholder executing this Agreement who is or becomes during the term hereof a director or officer of Parent or any subsidiary of Parent makes any agreement or understanding herein or is obligated hereunder in his or her capacity as such director or officer. The Stockholder signs solely in the Stockholder's capacity as the record holder and beneficial owner of the Stockholder's Shares. Nothing in this Agreement shall be construed to prohibit a Stockholder who is a member of the Board of Directors of Parent or any subsidiary of Parent or is an officer of Parent or any subsidiary of Parent from taking any action or inaction solely in such capacity or from taking any action or inaction with respect to any Parent Acquisition Proposal, Parent Superior Proposal or otherwise, as a member of, or at the direction of, the Board of Directors of Parent to the extent permitted by the Merger Agreement.

Section 2.05 Disclosure. The Stockholder hereby authorizes the Company to publish and disclose in the Joint Proxy Statement/Prospectus its identity and ownership of Shares and the nature of its commitments, arrangements and understandings under this Agreement.
