THE FOLLOWING IS THE PRESS RELEASE DISSEMINATED BY INFONAUTICS ON MARCH 28, 2001:

INFONAUTICS AND TUCOWS SIGN DEFINITIVE MERGER AGREEMENT
Strengthens Leading Distributor of Digital Applications and Content 

King of Prussia, PA (March 28, 2001) Infonautics, Inc. (NASDAQ: INFO), a pioneering provider of personalized information agents and Internet sites, and privately held Tucows Inc., a leading provider of wholesale digital products to Internet service providers and web hosting companies worldwide, announced today that they have signed a definitive merger agreement.

In consideration of the merger, Infonautics will issue approximately 50 million shares of Class A common stock to the Tucows shareholders who will own roughly 80% of the merged company at closing. Upon completion of the merger, which is subject to Infonautics and Tucows shareholder approval, certain regulatory approvals, and certain other closing conditions, Infonautics will remain a public company and is expected to adopt the Tucows name. The transaction is expected to close during the third quarter of 2001.

"Tucows met our combined criteria of growth, cash investment profile, content synergies, and future potential," stated Van Morris, President & Chief Executive Officer of Infonautics. "Tucows is in the financial sweet spot of the distribution chain for digital products such as domain registrations and digital certificates. Their distribution strategy resulted in a year 2000 increase of sales bookings to over $28 million from $4 million the previous year, and they entered 2001 with approximately $16 million in deferred revenue. This sales momentum coupled with Tucows' low cost distribution platform positions the combined company to be a significant player in a rapidly consolidating market."

"This transaction makes sense for both companies and will allow the combined company to capitalize on the numerous growth opportunities available to it," said Elliot Noss, President and CEO of Tucows. "To date, Tucows has demonstrated its ability to be a market leader in domain registrations, software distribution, and understanding the needs of ISPs and web hosting companies. We are uniquely positioned to benefit from the introduction of additional digital products, such as web certificates and messaging, to our distribution platform. This sets the stage for further growth."
