the reasonable judgment of the Board, that the Employee has failed to progress

the period of his or her employment. The term Confidential information"
includes, without limitation, financial information, business plans, prospects

Section 2.4.

2.8 EQUITABLE RELIEF. Employee acknowledges that his or her services to the
Company are of a unique character which give them a special value to the
Company. Employee further recognizes that violations by Employee of any one or
more of the provisions of this Section 2 may give rise to losses or damages

threatened, by Employee of the provisions of this Agreement. In the event of a
breach by the Employee of any of the provisions of Section 2, the Company shall
