As we discussed a few weeks back, among our top priorities as we go through the process of evaluating potential strategic options for the Company is the retention of our key staff members. Toward this end, we are providing our most valuable employees with incentives to remain with the Company during this process and to be committed to, and focused on, advancing the business and supporting our continued operations. Thus, the Company is pleased to offer you the following package of incentive payments and benefits, on and subject to the terms and conditions set forth below. Please read these terms and feel free to call us or Mary Sullivan with any questions you may have.

2000 Bonus: We are committing that the Company’s management bonus plan will be honored this year and bonuses for the calendar year 2000 will be paid in accordance with past practice. If there is a Change of Control of the Company during 2000, we will ensure that any successor commits to honoring the management bonus plan for your calendar year 2000 bonus.

Retention Bonus: You shall be eligible to receive a retention bonus of up to a total of US$215,000, based upon the following terms: (a) On July 1, 2001, you shall receive US$107,500, provided that you have not resigned from the Company or been terminated For Cause prior thereto, regardless of whether there has been a Transaction; (b) if there is a Transaction, and you are terminated Without Cause after July 1, 2001, but within two (2) years of the completion of the Transaction, you shall receive (in addition to the July 1 payment) an additional US$107,500; (c) if there is a Transaction and you are terminated Without Cause prior to July 1, 2001, you shall receive (in lieu of the July 1 payment) US$215,000.

Severance: If a Transaction occurs and you are terminated Without Cause by the Company within two (2) years after the completion of the Transaction, you will be entitled to a severance benefit at least equal to six (6) months of your base salary (at the time of such termination). This benefit will be payable, at the Company’s option, in either a lump sum or by salary continuation in accordance with the Company’s normal payroll procedures. This payment shall be in addition to any bonus that may be payable to you pursuant to the preceding paragraph. In the event you are entitled to other benefits in the nature of severance, whether under contract or law, the severance benefit payable under this paragraph shall be offset by the amount of such other severance benefits.

The Company will require any successor to expressly assume and agree to perform the obligations under this letter agreement.

Please make sure you have read the above and the attached terms and conditions and indicate your agreement with all of such terms and conditions by executing this letter agreement in the space provided below and returning it to Mary Sullivan.
