SPONSOR SUPPORT AGREEMENT; COVENANTS

Each Sponsor shall be bound by and comply with Sections 7.4 (No Solicitation by Acquiror) and 11.12 (Publicity) of the Merger Agreement (and any relevant definitions contained in any such Sections) to the same extent as such provisions apply to Acquiror as if such Sponsor was an original signatory to the Merger Agreement with respect to such provisions.

Section 1.2 No Transfer. During the period commencing on the date hereof and ending on the earliest of (a) the Effective Time, (b) such date and time as the Merger Agreement shall be terminated in accordance with Section 10.1 thereof (the earlier of (a) and (b), the “Expiration Time”) and (c) the liquidation of Acquiror, each Sponsor shall not (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly
