                NETWORK-1 REPORTS 2005 YEAR-END FINANCIAL RESULTS



     NEW YORK, NEW YORK APRIL 12, 2006-- Network-1 Security Solutions, Inc. (OTC
BB: NSSI-NEWS), a company specializing in the acquisition, licensing, and
protection of its intellectual property and proprietary technologies, today
announced financial results for the year ended December 31, 2005. Network-1
reported a net loss of ($1,332,000) for the year ended December 31, 2004 as
compared to a net loss of ($1,953,000) for the year ended December 31, 2005.
Included in net loss for 2005 are reversals of prior year accrued expenses of
$385,000.


     Net loss attributable to common stockholders for the year ended December
31, 2005 was $(1,832,000) or $(0.10) per share, which included a deemed dividend
of $500,000 relating to an extension to March 22, 2006 of the exercise period
for the Company's Series D warrants to purchase 1,352,152 shares of common
stock. The net loss attributable to common stockholders was ($3,405,000) or
($0.26) per share for the year ended December 31, 2004.


     Network-1 had no revenues for the year ended December 31, 2005. Cash and
cash equivalents were $938,000 at December 31, 2005. During the first quarter
ending March 31, 2006 all of the Series D warrants were exercised resulting in
aggregate proceeds to the Company of $1,493,726. At March 31, 2006, the Company
had approximately $2,034,000 in cash and cash equivalents which management
believes will be sufficient to fund its operations until December 2007.


     Highlights of the 2005 fiscal year included:

     o    During the first quarter, the Company completed the second closing of
          a private placement which resulted in aggregate gross proceeds to the
          Company of $2,685,000.

     o    During the third quarter of 2005, the Company settled its outstanding
          litigation with PowerDsine, Inc, which dismissed, with prejudice, a
          lawsuit brought by PowerDsine that sought a declaratory judgment that
          the Company's Remote Power Patent (U.S. Patent No. 6,218,930) was
          invalid and not infringed by PowerDsine and/or its customers.

     o    During the third quarter of 2005, the Company initiated patent
          litigation against D-Link Corporation and D-Link Systems, Inc. in the
          United States District Court for the Eastern District of Texas, Tyler
          Division for infringement of the Remote Power Patent. The date of the
          Markman hearing has been set for September 19, 2007 and the trial date
          has been set for March 2007.

     "We accomplished several key milestones in 2005 to help position Network-1
to bring further clarity to the value of the Company's Remote Power Patent",
commented Corey M. Horowitz, Chairman and CEO of Network-1. "We successfully
resolved the outstanding litigation with PowerDsine, and we established a date
for our Markman hearing on claim construction for September 19, 2006 in Tyler,
Texas in our litigation with D-Link. It is important to recognize that this
hearing will be a significant event as we proceed to trial on March 3, 2007.
While the outcome of the litigation is still uncertain, we have taken all the
steps necessary to ensure that our case will proceed in a timely manner and that
we have the capital required to protect our intellectual property."

     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 which has led to the rapid adoption of PoE.
