ITEM 8.01  OTHER EVENTS.

         On February 11, 2005, Celerity Systems, Inc. (the "Company") became
entitled to receive a distribution of $5,240,000 from Yorkville Advisors
Management, LLC ("Yorkville") in connection with the Company's Preferential
Rights Membership Interest in Yorkville, pursuant to the terms of Yorkville's
Limited Liability Company Agreement, as amended. Accordingly, upon its receipt
of the distribution, the Company will no longer have any ownership interest in
Yorkville. The Company's receipt of the Preferential Rights Membership Interest
was precipitated by the Managing Member of Yorkville announcing that Yorkville
will begin winding up its affairs and is expected to dissolve later this year
due to recently adopted rules and rule amendments by the Securities and Exchange
Commission.

         The Company's ownership interest in Yorkville was originally a minority
Common Membership Interest. Pursuant to the terms of a Second Amendment to the
Limited Liability Company Agreement of Yorkville entered into on January 31,
2005 among Yorkville and the other equity owners of Yorkville, the Company's
minority Common Membership Interest was reconstituted as Preferential Rights
Interest. As a result, the Company became entitled to receive dividends and
other distributions out of Yorkville's available assets in an amount up to the
purchase price paid by the Company for its original Common Membership Interest.
The $5,240,000 preferential distribution to be received by the Company
represents the entire purchase price paid by the Company for its original Common
Membership Interest.
