Item 4: Purpose of Transaction.

      The persons filing this Report have supported recent actions taken by the
Company to restore its profitability, but (a) continue to believe that the
Common Stock is significantly under-valued, (b) are concerned that steps taken
by the Company to date have been insufficient, as it is believed they may take
too long to positively impact share value, and (c) believe that management must
take further immediate steps to enhance shareholder value in order to prevent a
deterioration of the underlying value of the Company through its current
strategy of supporting under-performing business operations.

      The persons filing this Report have discussed their concerns with
management, other shareholders and potential financial and strategic investors
in the Company. The persons filing this Report are also examining all of their
options with respect to the possibility of taking actions, which they believe
will enhance shareholder value. Such actions could include proposing that
management pursue an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, encouraging, participating or leading a proxy
contest to change the Company's Chairman and/or Board of Directors and/or
encouraging, participating in or making a tender offer to acquire control of the
Company. Any such actions could relate to or result in one or more of the
matters referred to in paragraphs (a) through (j) of Item 4 of Schedule 13D.

      Each of the persons filing this Report also reserves the right to purchase
or otherwise acquire additional Common Stock or to sell or otherwise dispose of
Common Stock owned by it, in each case in open market or privately negotiated
transactions or otherwise.

Item 5: Interest in Securities of the Issuer.

      (a) Caxton International beneficially owns 877,400 shares of Common Stock,
representing approximately 5.4% of the total shares of Common Stock issued and
outstanding.

      Mr. Kovner is the Chairman and sole shareholder of Caxton Corporation,
and, as such, has voting and dispositive power with respect to

investments made by Caxton International. As a result of the foregoing, Mr.
Kovner may be deemed to beneficially own the Shares owned by Caxton
International.

Caxton International share the power to vote (or direct the vote) and the power
to dispose (or direct the disposition of) all of the Common Stock owned by
Caxton International.

      (c) Caxton International acquired the Common Stock owned by it in a series
of open market transactions effected primarily with independent brokers and, to
a lesser extent, directly with market makers utilizing the NASDAQ System,
between August 4, 1999 and December 9, 1999. See Schedule 1 for disclosure of
(1) the date, (2) the price and (3) the amount of shares purchased or sold by
Caxton International during the past 60 days.

      (d) No person other than the persons filing this Report is known to have
the right to receive or the power to direct the receipt of dividends from or the
proceeds from the sale of the Common Stock owned by them.

      (e) Not applicable.

        Securities of the Issuer.

      Except as described above, there are no contracts, arrangements,
understandings or relationships (legal or otherwise) among the persons filing
