     Intelligent Systems Software Believes R2 Technology Patent Infringement
                             Lawsuit Without Merit

June 5, 2002 - Intelligent Systems Software, Inc. (ISSI) and Howtek, Inc.
(NASDAQ:HOWT) jointly announced today that R2 Technology, Inc. has filed a
lawsuit against ISSI alleging that ISSI's MammoReader(TM) system infringes on
certain R2 patents. The complaint was filed in United States District Court for
the District of Delaware. The complaint asks for a permanent injunction against
further infringement and unspecified damages.

W. Kip Speyer, ISSI's President and Chief Executive Officer, said: "Our patent
counsel has reviewed the R2 patents and has advised Intelligent Systems that the
patent infringement claims are without merit." Mr. Speyer said, "ISSI intends to
vigorously defend the lawsuit."

According to Mr. Speyer and W. Scott Parr, Howtek's Chief Executive Officer,
"the lawsuit is not expected to have an impact on the proposed merger of Howtek
and ISSI."

In February 2002, ISSI announced that it had entered into a definitive agreement
with Howtek, Inc. to merge ISSI into Howtek. The proposed merger is subject to
the satisfaction of several conditions, including stockholder approval.
