termination, after the initial 12 months of employment with the Company, the
Company shall pay to Employee, a severance package consisting of the
Compensation (as set forth on Exhibit "B") and Benefits as described in
Paragraph 5 hereinabove ("Severance Package Compensation"), which would have

without cause, which occurs after the initial 24 months of employment by
Employee under this Agreement, the Severance Package Compensation shall be

during the initial 12 months of employment by Employee under this Agreement, no
severance payment shall be due as a result of such termination. The Severance
