                      NETWORK-1 ENTERS STRATEGIC AGREEMENT
                        WITH THINKFIRE SERVICES USA, LTD.

NEW YORK, December 2, 2004--Network-1 Security Solutions, Inc. (OTC: NSSI.OB)
announced today that it has entered into a strategic agreement with ThinkFire
Services USA, LTD. ("ThinkFire") pursuant to which ThinkFire will act as
worldwide licensing partner for United States Patent No. 6,218,930 owned by
Network-1 (the "Remote Power Patent").

ThinkFire was formed in 2001 by Nathan Myhrvold, former Chief Technical Officer
of Microsoft, and Daniel McCurdy, former President of the Intellectual Property
Business of Lucent Technologies, and previously a vice president at both IBM
Corporation and Ciena Corporation. ThinkFire's General Counsel, Thomas Reynolds,
was formerly Director of Patents for Intel Corporation. ThinkFire has provided
intellectual property advisory or representation services to some of the world's
most innovative companies, including Hewlett-Packard, NEC, Hitachi, Ciena,
Encyclopaedia Britannica, and more than a dozen other global technology leaders.
Since its inception, ThinkFire has initiated or completed licensing discussions
which it expects to result in royalties exceeding $350 million for its clients.
The Remote Power Patent relates to, among other things, the delivery of power
over Ethernet cables in order to remotely power network connected devices
including, among others, wireless switches, wireless access points, RFID card
readers, VOIP telephones and network cameras. In June 2003, the Institute of
Electrical and Electronic Engineers (IEEE) approved the IEEE 802.3af Power over
Ethernet ("PoE") standard (the "Standard") which has led to the rapid adoption
of PoE. According to industry analysts, annual revenues for several of the
markets adopting this technology each exceed or are projected to exceed $1
billion.

As previously disclosed, Network-1 is offering licenses to its technology to
those parties it believes will benefit from such a license. Network-1 believes
the relationship with ThinkFire will significantly enhance its ability to reach
the large number of companies utilizing the technology underlying the Remote
Power Patent.

"The fact that a firm of ThinkFire's caliber has agreed, after significant due
diligence, to undertake this licensing initiative is additional validation of
the market opportunity underlying the Remote Power Patent" commented Corey M.
Horowitz, Chairman and Chief Executive Officer of Network-1. "ThinkFire's
experience and outstanding team, combined with its extensive contacts in the
communications and information technology industries, makes them uniquely
qualified to undertake this licensing effort."

 "We have been very impressed with the work done by Network-1 on the Remote
Power Patent, including the identification of the market opportunity relating to
this technology" stated Daniel McCurdy, President and Chief Executive Officer of
ThinkFire. "It is clear to us that the Remote Power Patent is central to the
implementation of power over Ethernet solutions. We look forward to assisting
Network-1 in making this important invention broadly available, and thereby
speed the market adoption of power over Ethernet with its many economic and
ease-of-use benefits" continued Mr. McCurdy. Under the terms of the Master
Services Agreement between Network-1 and ThinkFire, Network-1 has granted to
ThinkFire the exclusive right to negotiate license agreements with select
potential licensees of the Remote Power Patent. In consideration of the value of
the services being rendered, Network-1 has agreed to pay ThinkFire a fee not to
exceed 20% of the royalty payments received by Network-1. The fees vary
depending on a variety of factors.
