      On March 15, 2005, we received a letter from Nasdaq advising that we would
have an additional 180 days (i.e., until September 12, 2005) to regain
compliance with Marketplace Rule 4310(c)(4) (i.e., minimum bid price) and that
we would regain compliance if, by September 12, 2005, the bid price for our
common stock closed at $1.00 per share or more for at least ten consecutive
business days.

Section 5 - Corporate Governance and Management.
Item 5.02 Departure of Directors or Principal Officers; Election of Directors;

      On March 14, 2004, the board of directors appointed Ronny Strauss to serve

committee and the Special Committee (as defined below). Mr. Strauss was employed
by Citicorp and its affiliates for 20 years in various capacities and has acted
as a financial advisor to various companies.

      In accordance with our compensation policies with respect to newly elected
or appointed members of the board, Mr. Strauss was granted a ten year option to
acquire 40,000 shares of our common stock at an exercise price of $1.19 per
share. In addition, as is the case with all directors who do not, directly or
indirectly, have a material business relationship with us, he is generally
entitled to an annual retainer of $20,000 and fees of $1,000 for each Board
meeting attended and $750 for each committee meeting (other than the audit
committee for which the fee is $1,000) attended in person or by telephone. Forty
percent of these retainer and meeting fees are paid in the form of our

      On March 14, 2004, the board selected five independent directors to serve

combination with a private company in a related line of business. No assurance
can be given that the special committee will recommend that this combination be
pursued or that if pursued, will be completed.

      These independent directors will be paid $10,000 (forty percent of which
will be paid in the form of our restricted stock units) for such service and are
not entitled to fees for participating in meetings of this committee.
