ST. PAUL, Minnesota and PRINCETON, New Jersey, October 25 /PRNewswire/ --

3M and Zargis Medical Corp., a spin-off from Siemens Corporate Research
(NYSE: SI) and a majority-owned subsidiary of Speedus Corp. (Nasdaq: SPDE)
today announced an exclusive multi-year marketing agreement involving Zargis'
heart sound analysis software and 3M Littmann's next-generation electronic
stethoscope.

Under the agreement, Zargis will support 3M in its efforts to develop a
next-generation stethoscope that will be compatible with Zargis' heart sound
analysis software. The date on which Zargis' software will become available
for use with a Littmann stethoscope has not yet been announced.

"This agreement builds on the rich Littmann brand legacy of advancing the
art of auscultation," said Chuck Kummeth, Vice President and General Manager,
3M Medical Division. "We are committed to bringing innovative solutions to
our customers, and this agreement with Zargis will help us do this well into
the future."

"We have been working closely with 3M for nearly two years to further
evaluate this market and refine our product strategy," stated Zargis CEO John
Kallassy. "We believe that the use of our software could enhance the
physician experience during every patient exam where a stethoscope is
currently used. This alliance with 3M will allow us to seamlessly integrate
our advanced sound analysis technology with 3M's next-generation electronic
stethoscopes and turn this vision into a reality on a global level."

In addition, the alliance provides Zargis with a wide-range of marketing
and promotional opportunities along with exclusive rights to sell its
ground-breaking heart sound analysis software through the global distribution
network of the Littmann brand. The agreement grants 3M a minority equity
position in Zargis, following the first sale of Zargis' software through the
3M distribution channel, and a seat on Zargis' board of directors.

Tom Miller, member of Siemens Medical's Executive Management Board,
stated, "We are very encouraged by this agreement and the progress Zargis has
made since it spun off from Siemens Corporate Research and we look forward to
continuing our support and seeing their business mature."
