Change in Control Bonus Program

September 18, 2001

b. Eligible Employees are those employees who were either full-time or part-time benefit eligible employees for the entire 12-month period preceding the Change in Control and who are employed by the Company on the date of the Change in Control. An approved leave of absence will count towards the 12-month period for eligibility. Employees who have received stock options for a total of 50,000 or more shares of the Company’s stock (without regard to vesting) are disqualified as Eligible Employees.

c. Employees who are represented by a union are not Eligible Employees unless this bonus program is expressly included within their collective bargaining agreement.

e. Employees employed in units in which we are a minority partner are eligible to participate in this program if they meet the above criteria.

III. Qualifying Change in Control

“Change in Control” shall mean:

a. Any transaction or series of transactions in which any person or group (within the meaning of Rule 13d-5 under the Securities Exchange Act of 1934 (the “Exchange Act”) and Sections 13(d) and 14(d) of the Exchange Act) becomes the direct or indirect beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of greater than 50% of the total voting power entitled to vote in the election of directors of the Company, including any transaction in which the Company becomes a wholly owned or majority owned subsidiary of another corporation.

2. If the Change in Control is a stock-for-stock transaction, the aggregate bonus shall equal 4% of the product of (x) the difference between the market value of the stock received per share of Company stock and $2.6875 and (y) the total shares outstanding on the date of the Change in Control.

b. The calculation of the premium realized shall be approved by the Company’s Board of Directors.
