ITEM 5.02   DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS; ELECTION OF DIRECTORS;
            APPOINTMENT OF PRINCIPAL OFFICERS.

       Effective as of November 17, 2004, the employment of Mr. Viaji Kumar, the
Company's Chief Operations Officer, ceased following the expiration of the term
of his employment agreement. The Company's decision not to renew Mr. Kumar's
employment agreement was not the result of any disagreement between Mr. Kumar
and the Company on any matter relating to the Company's operations, policies or
practices. No replacement for Mr. Kumar will be sought by the Company in light
of the Company's recently restructured operations and the appointment in April
2004 of a Chief Scientific Officer, whose responsibilities include those
typically performed by a chief operations officer.

       Pursuant to the requirements of the Securities Exchange Act of 1934, the
