FACE="Times New Roman" SIZE="2">A. It is expected that the Company from time to time will consider the possibility of a Change of Control. The Board of Directors of the Company (the &#147;<U>Board</U>&#148;) recognizes that such consideration can be
a distraction to the Employee and can cause the Employee to consider alternative employment opportunities. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">B. The Board believes that it
is in the best interests of the Company and its stockholders to provide the Employee with an incentive to continue Employee&#146;s employment and to maximize the value of the Company upon a Change of Control for the benefit of its stockholders.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">C. In order to provide the Employee with enhanced financial security and sufficient encouragement to remain with the Company
notwithstanding the possibility of a Change of Control, the Board believes that it is imperative to provide the Employee with certain severance benefits upon the Employee&#146;s termination of employment following a Change of Control. </FONT></P> <P
