INFONAUTICS MOVES TO OTC BULLETIN BOARD
DAY-TO-DAY OPERATIONS AND PENDING MERGER UNAFFECTED

King of Prussia, Pa., June 21, 2001, -- Infonautics, Inc. (OTCBB: INFO)
announced that its common stock, previously traded on the Nasdaq SmallCap
Market, commenced trading today on the OTC Bulletin Board.

Infonautics recently appealed to the Nasdaq Listing Qualifications Panel with
respect to a Nasdaq Staff Determination to remove the Company's listing on the
SmallCap Market for failure to maintain a minimum bid price of $1.00 for 30
consecutive trading days. The company received notification of the Panel's
determination to delist the Company's common stock from the SmallCap Market
effective today for non-compliance with the minimum bid price requirements of
Marketplace Rules 4310(c)(8)(B) and 4330(f).

"We are disappointed by this determination, but Infonautics' move to the OTC
Bulletin Board will not affect the company's day-to-day business operations,"
commented Van Morris, Infonautics' President and Chief Executive Officer.
"Despite this determination, Infonautics remains fully committed to the
completion of our pending merger with Tucows Inc. and we are working
aggressively towards closing the merger as soon as possible." Infonautics'
continued listing on the Nasdaq SmallCap Market is not a condition to closing
the company's merger with Tucows.
