WHEREAS, the Board of Directors of the Company (the “Board”) recognizes that the possibility of a Corporate Change (as hereinafter defined) may occur in the future and that the threat or the occurrence of a Corporate Change can result in significant distractions of the employees of the Company and its Affiliates because of the uncertainties inherent in such a situation; and

WHEREAS, the Board has determined that it is essential and in the best interest of the Company and its stockholders to retain the services of the Participants in the event of a threat or occurrence of a Corporate Change and to ensure each Participant’s continued dedication and efforts in such event without undue concern for his or her personal financial and job security; and

WHEREAS, to induce the Participants to remain in the service of the Company particularly in the event of a threat or the occurrence of a Corporate Change, the Company desires to put this Plan into place to provide the Participants with certain benefits in the event of their termination of employment in connection with a Corporate Change as provided herein.
