ITEM 1. DESCRIPTION OF BUSINESS.

            OVERVIEW

            The principal business of the Company is the acquisition,
development, licensing and protection of its intellectual property. The Company
presently owns six patents covering various telecommunications and data
networking technologies. The Company's strategy is to pursue licensing and
strategic business alliances with companies in industries that manufacture and
sell products that make use of the technologies underlying its patents as well
as with other users of the technology who benefit directly from the technology
including corporate, educational and governmental entities.

            On November 18, 2003, the Company acquired a portfolio of
telecommunications and data networking patents (the "Patent Portfolio") from
Merlot Communications, Inc., a broadband communications solutions provider. In
February 2004, following the acquisition of the Patent Portfolio and its review
of applicable markets, the Company commenced initial efforts to license its
Patent Portfolio. The Patent Portfolio consists of six patents issued by the
U.S. Patent Office that relate to various telecommunications and data networking
technologies and includes, among other things, patents covering systems and
methods for the transmission of audio, video and data over local area networks
(LANS) in order to achieve higher quality of service (QoS) and the control of
power delivery over LANs for the purpose of remotely powering network devices.

                                        1

            THE PATENTS

            The Company's Patent Portfolio consist of the following patents:

                        U.S. PATENT NO. 6,218,930: APPARATUS AND METHOD FOR
REMOTELY POWERING ACCESS EQUIPMENT OVER A 10/100 SWITCHED ETHERNET NETWORK;

                        U.S. PATENT NO. 6,577,631: COMMUNICATION SWITCHING
MODULE FOR THE TRANSMISSION AND CONTROL OF AUDIO, VIDEO, AND COMPUTER DATA OVER
A SINGLE NETWORK FABRIC;

                        U.S. PATENT NO. 6,574,242: METHOD FOR THE TRANSMISSION
AND CONTROL OF AUDIO, VIDEO, AND COMPUTER DATA OVER A SINGLE NETWORK
FABRIC;

                        U.S. PATENT NO. 6,570,890: METHOD FOR THE TRANSMISSION
AND CONTROL OF AUDIO, VIDEO, AND COMPUTER DATA OVER A SINGLE NETWORK FABRIC
USING ETHERNET PACKETS;

                        U.S. PATENT NO. 6,539,011: METHOD FOR INITIALIZING AND
ALLOCATING BANDWIDTH IN A PERMANENT VIRTUAL CONNECTION FOR THE TRANSMISSION
AND CONTROL OF AUDIO, VIDEO, AND COMPUTER DATA OVER A SINGLE NETWORK FABRIC; AND

                        U.S. PATENT NO. 6,215,789: LOCAL AREA NETWORK FOR THE
TRANSMISSION AND CONTROL OF AUDIO, VIDEO, AND COMPUTER DATA.

            The Company's future success is largely dependent upon its
proprietary technologies, its ability to protect its intellectual property
rights and consummate license agreements with respect to its Patent Portfolio.
The complexity of patent and common law, combined with the Company's limited
resources, create risk that its efforts to protect its proprietary technologies
may not be successful. The Company cannot be assured that its patents will be
upheld, or that third parties will not invalidate its patents. In March 2004,
PowerDsine Inc. commenced litigation against the Company seeking, among other
things, a declaratory judgment that the Company's patent covering remote
delivery of power over Ethernet cables (U.S. Patent No. 6,218,930) is invalid
(See "Risk Factors - We Face Uncertainty As To The Outcome of Litigation with
PowerDsine" and Item 3 "Legal Proceedings").

            In February 2004, the Company initiated its licensing efforts
relating to its patent (U.S. Patent No. 6,218,930) covering the control of power
delivery over Ethernet cables (the "Remote Power Patent"). The Remote Power
Patent application was filed on March 11, 1999 and the patent was granted by the
U.S. Office of Patent and Trademark on April 21, 2001. The Remote Power Patent
expires on March 11, 2019.

            As of March 31, 2004, the Company transmitted letters to
approximately 85 companies offering licenses to the Remote Power Patent. To date
the Company has not entered into any license agreements with third parties.

            The Company was incorporated under the laws of the State of Delaware
in July 1990. The Company's offices are located at 445 Park Avenue, Suite 1028,
New York, New York 10022 and its telephone number is (212) 829-5770.

            HISTORICAL BUSINESS

            From June 1995 until December 2002, the Company developed, marketed,
licensed and supported a suite of security software products designed to prevent
unauthorized access to information residing on networked servers, desktops and
laptops. In May 2003, the Company completed the sale of its security software
technology and related intellectual property to an unaffiliated foreign
corporation for an aggregate consideration of $415,000. In November 2003, the
Company entered the intellectual property licensing business following its
acquisition of the Patent Portfolio.

            MARKET OVERVIEW

            Management has determined that the Company's initial licensing
efforts will be focused on its Remote Power Patent. U.S. Patent No. 6,218,930
relates to several technologies which describe a methodology for controlling the
delivery of power to certain devices over an Ethernet network.

            The Institute of Electrical and Electronic Engineers (IEEE) is a
non-profit, technical professional association of more than 360,000 individual
members in approximately 175 countries. The Standards Association of the IEEE is
responsible for the creation of global industry standards for a broad range of
technology industries. In 1999, at the urging of several industry vendors, the
IEEE formed a task force to facilitate the adoption of a standardized
methodology for the delivery of remote power over Ethernet networks which would
insure interoperability among vendors of switches and terminal devices. On June
13, 2003 the IEEE Standards Association approved the 802.3af Power Over Ethernet
standard (the "Standard"), which covers technologies deployed in delivering
power over Ethernet cables. The Standard provides for the Power Sourcing
Equipment (PSE) to be deployed in switches or as standalone midspan hubs to
provide power to remote devices such as wireless access points, IP phones and
network based cameras. The technology is commonly referred to as Power Over
Ethernet ("PoE"). The Company believes its Remote Power Patent covers several of
the key technologies covered by the Standard.

            Ethernet is the leading local area networking technology in use
today. PoE technology allows for the delivery of power over Ethernet cables
rather than by separate power cords. As a result, a variety of network devices,
including IP telephones, wireless LAN Access Points, web-based network security
cameras, data collection terminals and other network devices, will be able to
receive power over existing data cables without the need to modify the existing
infrastructure to facilitate the provision of power for such devices through
traditional AC outlets. Advantages such as lower installation costs, remote
management capabilities, lower maintenance costs, centralized power backup, and
flexibility of device location as well as the advent of worldwide power
compatibility create the possibility of PoE becoming widely adopted in networks
throughout the world.

            PoE provides numerous benefits including quantifiable returns on
investment. The cost of hiring electricians to pull power cable to remote
locations used for access points or security cameras can rival or exceed the
cost of the devices. Another key benefit is the need for Voice over IP power
reliability in the face of power failures. Using PoE enables data center power
supply systems to ensure on-going power - a function that would be difficult and
expensive to implement if each phone required AC outlets.

                                        3
<PAGE>

            These and other advantages such as remote management capabilities,
lower maintenance costs, and flexibility of device location have led to
forecasts that PoE will be widely adopted in networks throughout the world.
International Data Corporation (IDC) forecasts that the annual PoE sales will
reach 134 million PSE switch ports (does not include midspan ports) by 2008
which equates to a 5 year compound annual growth rate of 63%. A recent Gartner
report estimates that PoE port shipments more than tripled in 2004 and that
price premiums for such ports ranged from $45 to $65 per port and that 18% of
all wiring closet switch ports shipped in 2004 were PoE-enabled.

            The benefits of PoE are compelling as evidenced by the introduction
of products by such leading vendors as 3Com, Seimens, Nortel Networks and Avaya,
as well as many others. In February 2004, Cisco Systems, Inc., the world's
largest network switch manufacturer, announced that all of its switches will
ultimately be PoE enabled. PowerDsine, Inc., the world's leader in PoE
technology and a founding member of the IEEE Task Force that developed the
Standard, and Motorola, Inc., have announced a partnership to develop chip-based
PoE solutions thereby reducing cost and the number of components necessary to
deliver manufactured Standard compliant products.

            The Company believes the cost savings as well as the other benefits
that can be realized by utilizing the technology contained in the Remote Power
Patent may be of significant importance to the growth of the Wireless Local Area
Networking (WLAN) industry and Voice Over IP Telephony (VOIP) industry.
According to In-Stat/MDRs, a market research firm, purchases of wireless
hardware, including Access Points for IEEE 802.11b/g (Wi-Fi) networks, reached
$2.2 billion in 2002 and are expected to exceed $3.9 billion by 2006. A January
2004 market study by The Dell'Oro Group, a research firm, projects that annual
shipments of enterprise wireless LAN access points will grow from 882,000 units
in 2003 to 5.9 million units in 2008, representing a compound annual growth rate
of 46.2%.

            The VOIP market is currently one of the fastest growing segments in
the telecommunications industry. VOIP traffic has steadily increased over the
last several years and is being deployed by service providers and carriers
worldwide. IDC, a market research firm, estimates that worldwide IP telephone
unit sales are set to grow from 1.5 million units in 2003 to nearly 5 million
units in 2007 and overall voice-over IP equipment, which in 2003 represented a
market of $3.3 billion, is expected to grow at a compound annual growth rate of
45.0% to $15.1 billion by 2007.

            The ability to supply power to end-devices through Ethernet cables
can be applied to other end-devices, such as advanced security cameras, RFID
card readers, laptop computers, personal digital assistants and portable digital
music players. As the desire to connect more end-devices to the Ethernet network
grows, the Company believes that PoE technology will become more widely used as
a method to power these end-devices.

            The Company also owns five (5) additional patents covering various
methodologies that provide for allocating bandwidth and establishing Quality of
Service for delay sensitive data, such as voice, on packet data networks.
Quality of Service issues become important when data networks carry packets that
contain audio and video which may require priority over data packets traveling
over the same network. Covered within these patents are also technologies that
establish bi-directional

                                        4
<PAGE>

communications control channels between network-connected devices in order to
support advanced applications on traditional data networks. The Company believes
that potential licensees of the technologies contained in these patents would be
vendors deploying applications that require the low latency transport of delay
sensitive data such as video over data networks.

            NETWORK-1 STRATEGY

            The Company's strategy is to capitalize on its Patent Portfolio
through entering into licensing arrangements with third parties including
manufacturers and users that utilize the Patent Portfolio's proprietary
technologies as well as any additional proprietary technologies covered by
patents which may be acquired by the Company in the future. The Company will
also seek to enter into licensing arrangements with users of the proprietary
technologies, including corporate, educational and governmental entities in
those cases where the patent rights extend to the users of the technologies
contained in manufactured products.

            The Company does not anticipate manufacturing products utilizing the
Patent Portfolio or any of the proprietary technologies contained in the Patent
Portfolio. Accordingly, the Company does not anticipate establishing a
manufacturing, sales or marketing infrastructure. Consequently, the Company
believes that its capital requirements will be less than the capital
requirements for companies with such infrastructure requirements.

            In connection with the Company's activities relating to the
protection of its Patent Portfolio, it may be necessary to assert patent
infringement claims against third parties that the Company believes are
infringing its Patent Portfolio. Such litigation may be costly and based on the
Company's current limited financial resources, it may not be able to pursue
litigation as aggressively as companies with substantially greater financial
resources.

            MARKETING AND DISTRIBUTION

            In February 2004, the Company commenced licensing efforts for its
Remote Power Patent. The Company believes that potential licensees include,
among others, Wireless Local Area Networking (WLAN) equipment manufacturers,
Local Area Networking (LAN) equipment manufacturers, Voice Over IP Telephony
(VOIP) equipment manufacturers, and Network Camera manufacturers. In addition,
the Company believes that additional potential licensees include users of the
equipment embodying the PoE technology covered by its Remote Power Patent,
including corporate, educational and federal, state and local government users,
as they are significant beneficiaries of the technologies covered by the Remote
Power Patent.

            ThinkFire Agreement

            On November 30, 2004, the Company entered into a Master Services
Agreement (the "Agreement") with ThinkFire Services USA, Ltd. ("ThinkFire")
pursuant to which ThinkFire has been granted the exclusive (except for direct
efforts by the Company and related companies) worldwide rights to negotiate
license agreements for the Company's Remote Power Patent with respect to certain
potential licensees agreed to between the

                                        5
<PAGE>

parties. Either the Company or ThinkFire may terminate the Agreement upon 60
days notice for any reason or upon 30 days notice in the event of a material
breach. The Company has agreed to pay ThinkFire a fee not to exceed 20% of the
royalty payments received from license agreements consummated by ThinkFire on
its behalf.

            COMPETITION

            The telecommunications and data networking licensing market is
characterized by intense competition and rapidly changing business conditions,
customer requirements and technologies. The Company's current and potential
competitors have longer operating histories, greater name recognition and
possess substantially greater financial, technical, marketing and other
competitive resources than the Company. Although Management believes that the
Company has enforceable patents relating to telecommunications and data
networking, there can be no assurance that the Patent Portfolio will be upheld
or that third parties will not invalidate any or all of the patents in the
Patent Portfolio. In addition, the Company's current and potential competitors
may develop technologies that may be more effective than the Company's
proprietary technologies or that would render the Company's technologies less
marketable or obsolete. The Company may not be able to compete successfully.

            In addition, other companies may develop competing technologies that
offer better or less expensive alternatives to PoE and the other technologies
covered by the Patent Portfolio. Several companies have notified the IEEE that
they may have patents and proprietary technologies that are covered by the
Standard. In the event any of those companies assert claims relating to its
patents, the licensing royalties available to the Company may be limited.
Moreover, technological advances or entirely different approaches developed by
one or more of its competitors or adopted by various standards groups could
render the Company's Remote Power Patent obsolete, less marketable or
unenforceable.

            EMPLOYEES AND CONSULTANTS

            As of March 31, 2005, the Company had one full time employee, no
part time employees and three consultants.



            RISK FACTORS THAT MAY AFFECT FUTURE RESULTS

            The Company operates in a highly competitive environment that
involves a number of risks, some of which are beyond the Company's control. The
following discussion highlights the most material of the risks.

            WE HAVE A HISTORY OF LOSSES AND NO REVENUE FROM CURRENT OPERATIONS.

            We have incurred substantial operating losses since our inception,
which has resulted in an accumulated deficit of $(42,989,000) as of December 31,
2004. For the years ended December 31, 2004 and 2003, we incurred net losses of
$(1,953,000) and $(614,000), respectively. We have financed our operations
primarily by sales of equity securities as well as the sale of our CyberWall
PLUS security software technology in May 2003. Since December 2002, when we
discontinued our security software products and following the commencement of
our new technology licensing business in

                                        6
<PAGE>

November 2003, we have not had material revenue from operations and for the year
ended December 31, 2004 we had no revenue from operations. Our ability to
achieve revenue and generate positive cash flow from operations is dependent
upon consummating licensing agreements with respect to our patented technology.
We may not be successful in achieving licensing agreements with third parties
and our failure to do so would have a material adverse effect on our business,
financial condition and results of operations. We may not be able to achieve
revenue or generate positive cash flow from operations from our new licensing
business.

            WE COULD BE REQUIRED TO STOP OPERATIONS IF WE ARE UNABLE TO DEVELOP
OUR TECHNOLOGY LICENSING BUSINESS OR RAISE CAPITAL WHEN NEEDED.

            We anticipate, based on our currently proposed plans and assumptions
relating to our operations (including the timetable of, costs and expenses
associated with our continued operations), that our current cash position will
more likely than not be sufficient to satisfy our operations and capital
requirements until September 2006. However, we may expend our funds prior
thereto. In the event our plans change, or our assumptions change or prove to be
inaccurate (due to unanticipated expenses, difficulties, delays or otherwise),
we could have insufficient funds to support our operations prior to September
2006. Our inability to obtain additional financing when needed, absent
generating sufficient cash from licensing arrangements, would have a material
adverse effect on the Company, requiring us to curtail or possibly cease our
operations. In addition, any additional equity financing may involve substantial
dilution to the interests of our then existing stockholders.

            OUR NEW LICENSING BUSINESS MAY NOT BE SUCCESSFUL.

            In November 2003, we entered the technology licensing business as a
result of our acquisition of six patents relating to various telecommunications
and data networking technologies including, among others, patents covering the
transmission of audio, video and data over computer and telephony networks and
the delivery of remote power over Ethernet. Accordingly, we have a very limited
history in the technology licensing business upon which an evaluation of our
prospects and future performance can be made. Our prospects must be considered
in light of the risks, expenses and difficulties frequently encountered in the
development, operation and expansion of a new business based on patented
technologies in a highly specialized and competitive market. We may not be able
to achieve revenue or profitable operations from our new licensing business.

            OUR FUTURE SOURCE OF LICENSING REVENUE IS UNCERTAIN.

            In February 2004, we initiated our first licensing efforts relating
to the technologies in our remote power patent (U.S. Patent No. 6,218,930) (the
"Remote Power Patent"). To date, we have not entered into any licensing
agreements with third parties with respect to our Remote Power Patent or our
other patented technologies. Our inability to consummate licensing agreements
and achieve revenue from our patented technologies would have a material adverse
effect on our operations and our ability to continue our business. In addition,
in the event we consummate license arrangements with third parties, such
arrangements are not likely to produce a stable or

                                        7
<PAGE>

predictable stream of revenue in the foreseeable future. Furthermore, the
success of our licensing efforts depends upon the strength of our intellectual
property rights.

            WE ARE CURRENTLY RELYING UPON THE EFFORTS OF THINKFIRE TO CONSUMMATE
            LICENSING AGREEMENTS FOR OUR REMOTE POWER PATENT WITH CERTAIN SELECT
            POTENTIAL LICENSEES.

            On November 30, 2004, we entered into a Master Services Agreement
(the "Agreement") with ThinkFire Services USA, Ltd. ("ThinkFire") pursuant to
which ThinkFire has been granted the exclusive (except for us and related
companies) worldwide rights to negotiate license agreements for the Remote Power
Patent with respect to certain potential licensees agreed between the parties.
Either we or ThinkFire can terminate the Agreement upon 60 days notice for any
reason or upon 30 days notice in the event of a material breach. We have agreed
to pay ThinkFire a fee not to exceed 20% of the royalty payments received from
license agreements consummated by ThinkFire on our behalf. There is no assurance
that ThinkFire will be successful in consummating license agreements on our
behalf or that such agreements will result in significant royalty payments to
us.

            OUR SUCCESS IS DEPENDENT UPON OUR ABILITY TO PROTECT OUR PROPRIETARY
            TECHNOLOGIES.

            Our success is substantially dependent upon our proprietary
technologies and our ability to protect our intellectual property rights. We
currently hold 6 patents issued by the U.S. Patent Office that relate to various
telecommunications and data networking technologies and include among other
things, patents covering the transmission of audio, voice and data over computer
and telephony networks and the delivery of remote PoE networks. We rely upon our
patents and trade secret laws, non-disclosure agreements with our employees,
consultants and third parties to protect our intellectual property rights. The
complexity of patent and common law, combined with our limited resources, create
risk that our efforts to protect our proprietary technologies may not be
successful. We cannot assure you that our patents will be upheld or that third
parties will not invalidate our patent rights. In the event our intellectual
property rights are not upheld, such an event would have a material adverse
effect on our company. In addition, there is a risk that third parties may
independently develop substantially equivalent or superior technologies.

            ANY LITIGATION TO PROTECT OUR INTELLECTUAL PROPERTY OR ANY THIRD
            PARTY CLAIMS TO INVALIDATE OUR PATENTS COULD HAVE A MATERIAL ADVERSE
            EFFECT ON OUR BUSINESS.

            Our success depends on our ability to protect our intellectual
property rights. In the future, it may be necessary for us to commence patent
litigation against third parties whom we believe require a license to our
patents. In addition, we may be subject to third-party claims seeking to
invalidate our patents, as is the case with the action commenced by PowerDsine
relating to our Remote Power Patent as discussed below. These types of claims,
with or without merit, may subject us to costly litigation and diversion of
management's focus. In addition, based on our limited financial resources, we
may not be able to pursue litigation as aggressively as others with
substantially greater financial resources. Based on our limited financial
resources, it may be

                                        8
<PAGE>

necessary to engage third party professionals on a contingency basis pursuant to
which such parties would be entitled to share in the proceeds of any successful
enforcement of our intellectual property rights. If third parties making claims
against us seeking to invalidate our patent are successful, they may be able to
obtain injunctive or other equitable relief, which effectively could block our
ability to license or otherwise capitalize on our proprietary technologies.
Successful litigation against us resulting in a determination that our patents
are invalid would have a material adverse effect on our company.

            WE FACE UNCERTAINTY AS TO THE OUTCOME OF LITIGATION WITH POWERDSINE.

            On March 31, 2004, PowerDsine Inc. ("PowerDsine") commenced an
action against us in the United District Court, Southern District of New York
(Civil Action No. 04 CV 2502) seeking a declaratory judgment that our Remote
Power Patent is invalid and is not infringed by PowerDsine and/or its customers.
PowerDsine further seeks an order permanently enjoining us (i) from making any
claims to any person or entity that PowerDsine's products infringe the Remote
Power Patent or contribute to infringement of the patent, (ii) from interfering
with or threatening to interfere with the importation, sale, license or use of
PowerDsine's PoE components or products, and (iii) from instituting or
prosecuting any lawsuit or proceeding placing at issue the right of PowerDsine,
its customers, licensees, successors, or assigns to import, use or sell
PowerDsine's PoE components or products. We believe our Remote Power Patent is
valid and that we have meritorious defenses to the action. On December 1, 2004,
we moved to dismiss the declaratory judgment action asserting, among other
things, that there is no actual case or controversy because PowerDsine did not
have reasonable apprehension of suit at the time the case was filed, and
therefore, the court lacks jurisdiction over the matter. On January 21, 2005 our
motion to dismiss was denied. We have engaged in settlement discussions with
PowerDsine in an effort to resolve the litigation. In the event that we are
unable to settle the litigation, we intend to vigorously defend the lawsuit and
take whatever actions are necessary to protect our intellectual property. In the
event, however, that the Court granted the declaratory judgment and our Remote
Power Patent was determined to be invalid, such a determination would have a
material adverse effect on us. Regardless of the outcome, this litigation may
subject us to significant costs and diversion of management time.

            MATERIAL LICENSING REVENUES FROM OUR REMOTE POWER PATENT MAY BE
DEPENDENT UPON THE APPLICABILITY OF THE IEEE STANDARD.

              The Institute of Electrical and Electronic Engineers (IEEE) is a
non-profit, technical professional association of more than 360,000 individual
members in approximately 175 countries. The Standards Association of the IEEE is
responsible for the creation of global industry standards for a broad range of
technology industries. In 1999, at the urging of several industry venders, the
IEEE formed a task force to facilitate the adoption of a standardized
methodology for the delivery of remote power over Ethernet networks which would
insure interoperability among vendors of switches and terminal devices. In June
2003, the IEEE Standards Association approved the 802.3af Power Over Ethernet
standard (the "Standard"), which covers technologies deployed in delivering
power over Ethernet cables including whether deployed in switches or as
standalone midspan hubs both of which provide power to remote devices including
wireless access points, IP phones and network based cameras. The technology is

                                        9
<PAGE>

commonly referred to as Power Over Ethernet ("PoE"). We believe our Remote Power
Patent covers several of the key technologies covered by the Standard. However,
there is a risk that as a result of litigation a court may determine otherwise
and such a determination would have a material adverse effect on our ability to
enter into license agreements and achieve revenue and profits from our Remote
Power Patent.

            WE FACE INTENSE COMPETITION AND WE MAY NOT BE ABLE TO SUCCESSFULLY
COMPETE.

            The telecommunications and data networking market is characterized
by intense competition and rapidly changing business conditions, customer
requirements and technologies. Our current and potential competitors have longer
operating histories, greater name recognition and possess substantially greater
financial, technical, marketing and other competitive resources than us.
Although we believe that we have rights to enforceable patents relating to
telecommunications and data networking, there can be no assurance that third
parties will not invalidate any or all of our patents. In addition, the
telecommunications and data networking industries may develop technologies that
may be more effective than our proprietary technologies or that render our
technologies less marketable or obsolete.

            OUR MARKETS ARE SUBJECT TO RAPID TECHNOLOGICAL CHANGE AND OUR
TECHNOLOGIES FACE POTENTIAL TECHNOLOGY OBSOLESCENCE.

            The telecommunications and data networking technology market
including, transmission of audio, video and data over computer and telephony
networks and the delivery of remote power over Ethernet markets, are
characterized by rapid technological changes, changing customer requirements,
frequent new product introductions and enhancements, and evolving industry
standards. The introduction of products embodying new technologies and the
emergence of new industry standards may render our technologies obsolete or less
marketable. To the extent we are able to achieve revenue in the future, such
revenue will be derived from licensing our technologies based on existing and
evolving industry standards.

            DEPENDENCE UPON CEO AND CHAIRMAN.

            Our success will largely be dependent upon the personal efforts of
Corey M. Horowitz, Chairman and Chief Executive Officer and Chairman of the
Board of Directors. On November 26, 2004, we entered into a two (2) year
employment agreement with Mr. Horowitz pursuant to which he will continue to
serve as our Chairman and Chief Executive Officer. We do not maintain key man
life insurance on the life of Mr. Horowitz. The loss of the services of Mr.
Horowitz would have a material adverse effect on our business and prospects.

            RISKS RELATED TO LOW PRICED STOCKS.

            Our common stock currently trades on the OTC Bulletin Board under
the symbol NSSI.OB. Since the trading price of our common stock is below $5.00
per share, our common stock is considered a penny stock. SEC regulations
generally define a penny stock to be an equity security that is not listed on
Nasdaq or a national securities exchange and that has a market value of less
than $5.00 per share, subject to certain

                                       10
<PAGE>

exceptions. SEC regulations require broker-dealers to deliver to a purchaser of
our common stock a disclosure schedule explaining the penny stock market and the
risks associated with it. Various sales practice requirements are also imposed
on broker-dealers who sell penny stocks to persons other than established
customers and accredited investors (generally institutions). Broker-dealers must
also provide the customer with current bid and offer quotations for the penny
stock, the compensation of the broker-dealer and monthly account statements
disclosing recent price information for the penny stock held in the customer's
account.

            THE SIGNIFICANT NUMBER OF OPTIONS AND WARRANTS OUTSTANDING MAY
ADVERSELY EFFECT THE MARKET PRICE FOR OUR COMMON STOCK.

            As of March 31, 2005, there are outstanding (i) options and warrants
to purchase an aggregate of 10,710,905 shares of our common stock at exercise
prices ranging from $.12 to $10.13, and (ii) 207,630 additional shares of our
common stock which may be issued in the future under our stock option plan. To
the extent that outstanding options and warrants are exercised, stockholder
percentage ownership will be diluted and any sales in the public market of the
common stock underlying such options may adversely affect prevailing market
prices for our common stock.

            WE HAVE A SIGNIFICANT AMOUNT OF AUTHORIZED BUT UNISSUED PREFERRED
STOCK, WHICH MAY AFFECT THE LIKELIHOOD OF A CHANGE OF CONTROL IN OUR COMPANY.

            Our Board of Directors has the authority, without further action by
the stockholders, to issue 10,000,000 shares of preferred stock on such terms
and with such rights, preferences and designations as our Board of Directors may
determine. Such terms may include restricting dividends on our common stock,
dilution of the voting power of our common stock or impairing the liquidation
rights of the holders of our common stock. Issuance of such preferred stock,
depending on the rights, preferences and designations thereof, may have the
effect of delaying, deterring or preventing a change in control. In addition,
certain "anti-takeover" provisions in Delaware law may restrict the ability of
our stockholders to authorize a merger, business combination or change of
control.


ITEM 2. DESCRIPTION OF PROPERTY

            The Company currently leases office space in New York City at a cost
of $3,150 per month. The lease is for six months with automatic renewals unless
terminated upon 60 days notice.

ITEM 3. LEGAL PROCEEDINGS

            PowerDsine Litigation

            On March 31, 2004, PowerDsine Inc. commenced an action against the
Company in the United District Court, Southern District of New York (Civil
Action No. 04 CV 2502) seeking a declaratory judgment that the Company's Remote
Power Patent (U.S. Patent No. 6,218,930) is not infringed by PowerDsine and/or
its customers. PowerDsine further seeks an order permanently enjoining the
Company (i) from making

                                       11
<PAGE>

any claims to any person or entity that PowerDsine's products infringe the
Remote Power Patent or contribute to infringement of the patent, (ii) from
interfering with or threatening to interfere with the importation, sale, license
or use of PowerDsine's PoE components or products, and (iii) from instituting or
prosecuting any lawsuit or proceeding placing at issue the right of PowerDsine,
its customers, licensees, successors, or assigns to import, use or sell
PowerDsine's PoE components or products. The Company believes its Remote Power
Patent is valid and it has meritorious defenses to the action. On December 1,
2004, we moved to dismiss the declaratory judgment action asserting, among other
things, that there is no actual case or controversy because PowerDsine did not
have reasonable apprehension of suit at the time the case was filed, and
therefore, the court lacks jurisdiction over the matter. On January 21, 2005 our
motion to dismiss was denied. The Company intends to vigorously defend the
action and take whatever actions are necessary to protect its intellectual
property. In the event, however, that the Court granted the declaratory judgment
and the patent was determined to be invalid, such a determination would have a
material adverse effect on the Company.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

            THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION
WITH THE COMPANY'S FINANCIAL STATEMENTS, INCLUDING THE NOTES THERETO, INCLUDED
ELSEWHERE IN THIS FORM 10-KSB. EXCEPT FOR THE HISTORICAL INFORMATION CONTAINED
HEREIN, THIS DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS
AND UNCERTAINTIES, INCLUDING, BUT NOT LIMITED TO, THOSE DISCUSSED IN THE SECTION
ABOVE ENTITLED "RISK FACTORS WHICH MAY AFFECT FUTURE RESULTS" IN ITEM 1 OF THIS
REPORT AS WELL AS THOSE RISKS DISCUSSED IN THIS SECTION AND ELSEWHERE IN THIS
REPORT. BECAUSE SUCH STATEMENTS INVOLVE RISKS AND UNCERTAINTIES, ACTUAL RESULTS
MAY DIFFER MATERIALLY FROM THOSE EXPRESSED OR IMPLIED BY SUCH FORWARD-LOOKING
STATEMENTS.

            OVERVIEW

            The principal business of the Company is the acquisition,
development, licensing and protection of its intellectual property. The Company
presently owns six patents covering various telecommunications and data
networking technologies. The Company's strategy is to pursue licensing and
strategic business alliances with companies in the industries that manufacture
and sell products that make use of the technologies underlying its patents as
well as with other users who benefit directly from the technology including
corporate, educational and governmental entities.

            On November 18, 2003, the Company acquired a portfolio of
telecommunications and data networking patents (the "Patent Portfolio") from
Merlot Communications, Inc., a broadband communications solutions provider. The
Patent Portfolio consists of six patents issued by the U.S. Patent Office that
relate to various telecommunications and data networking technologies and
includes, among other things, patents covering the transmission of audio, video
and data over computer and telephony networks and the delivery of power over
Ethernet networks for the purpose of remotely powering network devices.

            In February 2004, the Company initiated licensing efforts relating
to one of its patents (U.S. Patent No. 6,218,930) covering the remote delivery
of power over Ethernet cable (the "Remote Power Patent"). As of the date of this
Report, the Company has not entered into any license arrangement with respect to
the Remote Power Patent, although it is pursing such arrangements with third
parties. The Company does not currently have any revenue from operations. The
success of the Company and its ability to achieve revenue is largely dependent
on its ability to consummate licensing arrangements with third parties. In
November 2004, the Company entered into an agreement with ThinkFire Services
USA, Ltd. ("ThinkFire") pursuant to which ThinkFire has been granted the
exclusive worldwide rights to negotiate license agreements for the Remote Power
Patent with certain agreed-upon potential licensees. The Company has agreed to
pay ThinkFire a fee not to exceed 20% of the royalty payments received from
license agreements consummated by ThinkFire on its behalf.

            The Company's success depends on its ability to protect its
intellectual property rights. In the future, it may be necessary for the Company
to commence patent

                                       14
<PAGE>

litigation against third parties who it believes are infringing its patents. In
addition, third parties may seek to invalidate the Company's patents, as is the
case with the action commenced by PowerDsine (see Item 3 "Legal Proceedings").
The costs of litigation are significant and based on the Company's limited
financial resources, it may be necessary to engage attorneys on a contingency
basis pursuant to which counsel would be entitled to share in the proceeds of
any successful enforcement of the Company's intellectual property rights. If
third parties making claims against the Company seeking to invalidate the
Company's patents are successful, they may be able to obtain injunctive or other
equitable relief, which could effectively block the Company's ability to license
or otherwise capitalize on its proprietary technologies. If the Company is not
successful in protecting its patents in litigation and its patents are
determined to be invalid, such determinations would have a material adverse
effect on the Company.

            On December 21, 2004 and January 13, 2005, the Company completed a
private offering of its equity securities resulting in gross proceeds of
$2,685,000. The Company anticipates that such proceeds will more likely than not
be sufficient to support its operations until September 2006. (See "Liquidity
and Capital Resources" at page 18 hereof)

            To date the Company has incurred significant losses and at December
31, 2004, had an accumulated deficit of $(42,989,000). At March 31, 2005, the
Company had approximately $1,722,000 of cash and cash equivalents. Management
believes that based on its current cash position, the Company has sufficient
capital to fund its operations until September 2006, although there is no
assurance that the Company will not have sufficient capital prior to such date.
(See "Liquidity and Capital Resources" at page 18 hereof).

CRITICAL ACCOUNTING POLICIES:

            Patents:

            The Company owns a Patent Portfolio that relates to various
telecommunications and data networking technologies. The Company capitalizes the
costs associated with acquisition, registration and maintenance of the patents
and amortizes these assets over their remaining useful lives on a straight-line
basis. Any further payments made to maintain or develop the patents would be
capitalized and amortized over the balance of the useful life for the patents.

            Impairment of long-lived assets:

            In accordance with Statement of Financial Accounting Standards
("SFAS") No. 144, "Accounting for the Impairment or Disposal of Long-Lived
Assets", the Company records impairment losses on long-lived assets used in
operations or expected to be disposed of when indicators of impairment exist and
the cash flows expected to be derived from those assets are less than carrying
amounts of those assets.

                                       15
<PAGE>

            Use of estimates:

            The preparation of financial statements in conformity with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

            RESULTS OF OPERATIONS


YEAR ENDED DECEMBER 31, 2004 COMPARED TO YEAR ENDED DECEMBER 31, 2003.

            The Company had no revenues for the year ended December 31, 2004
("2004") compared to revenues of $218,000 for the year ended December 31, 2003
("2003). Revenues of $218,000 during 2003 included $130,000 related to the
amortization of deferred revenue with a former strategic partner and $88,000
related to the amortization of deferred maintenance revenues from customers who,
in earlier periods, had elected to purchase maintenance and support for the
Company's contracts for its software product line which was discontinued in
December 2002.

            The Company did not incur any cost of revenue for 2004 as compared
to $51,000 for 2003, which was related to the cost of one employee who provided
support services for former customers of the Company's software business. There
was no gross profit for 2004 compared to gross profit of $167,000 for 2003.

            General and administrative expenses include employee costs,
including salary, benefits, travel and other related expenses associated with
management, finance and accounting operations, and legal and other professional
services provided to the Company. General and administrative expenses increased
by $748,000 or 62%, to $1,956,000 in 2004 from $1,208,000 in 2003. The increase
in general and administrative expenses was primarily due to an increase in legal
and other professional fees incurred in connection with the acquisition of the
patent portfolio and related licensing efforts as well as the recognition of
expenses relating to the valuation of stock options issued by the Company.

            Interest income decreased by $9,000 or 75% to $3,000 in 2004 from
$12,000 in 2003 primarily due to the increased funds used for operations and a
decrease in funds available for short term investments.

            On May 30, 2003, the Company completed the sale of its CyberwallPlus
technology and related intellectual property (the "Assets") and assignment of
rights under the FalconStor license agreement for $415,000. The carrying value
of the Assets were written down to zero in the third quarter of 2002. The
$415,000 sales price is included as "Gain on Sale of Assets" in the statements
of operations for 2003.

            No provision for or benefit from federal, state or foreign income
taxes was recorded for 2004 or 2003 since the Company incurred net operating
losses for each year and fully reserved its deferred tax assets as their future
realization could not be determined.

            As a result of the foregoing, the net loss was $1,953,000 for 2004
as compared to a net loss of $614,000 for 2003.

            On December 21, 2004, the Company extended the exercise period for
warrants to purchase 1,352,152 shares of Common Stock issued in connection with
a Company financing in December 1999. The associated expense with respect to the
warrant

                                       17

extension was recorded as a deemed dividend in the amount of $1,179,000 in 2004
causing the net loss attributable to common stockholders to be $3,132,000.

            LIQUIDITY AND CAPITAL RESOURCES

            At December 31, 2004, the Company had $2,177,000 of cash and cash
equivalents and working capital of $1,335,000. The Company has financed its
operations primarily through the sale of equity and debt securities, and the
sale of its security software technology in May 2003. Net cash used in operating
activities was $842,000 in 2004 as compared to $1,360,000 in 2003. Net cash used
in operating activities for 2004 was primarily attributable to the net loss of
$1,953,000, an increase in accounts payable, accrued expenses and other current
liabilities of $344,000 and the expenses related to the valuation of stock
options and warrants.

            Net cash used in investing activities during 2004 was financed with
the remaining funds of $415,000 received from the sale of its CyberwallPlus
software and related intellectual property in May 2003. The Company does not
currently have a line of credit from a commercial bank or other institution.

            In December 2004 and January 2005, the Company completed a private
offering of its equity securities, consisting of an aggregate of 2,685,000
shares of common stocks and warrants to purchase an aggregate of 2,013,750
shares of common stock, resulting in gross proceeds to the Company of
$2,685,000.

            The Company anticipates, based on currently proposed plans and
assumptions, relating to its operations that its cash balance of approximately
$1,722,000 as of March 31, 2005 will more likely than not be sufficient to
satisfy the Company's operations and capital requirements until September 2006.
There can be no assurance, however, that such funds will not be expended prior
thereto. In the event the Company's plans change, or its assumptions change, or
prove to be inaccurate (due to unanticipated expenses, difficulties, delays or
otherwise), the Company may have insufficient funds to support its operations
prior to September 2006. The Company is currently pursuing licensing
opportunities for its Remote Power Patent, however, to date the Company has not
entered into any such licensing arrangements. The Company's inability to
consummate licensing arrangements and derive revenues therefrom on a timely
basis or obtain additional financing when needed would have a material adverse
effect on the Company, requiring it to curtail or cease operations. In addition,
any equity financing may involve substantial dilution to the stockholders of the
Company.

DIRECTOR COMPENSATION

            The Company has compensated each director, who is not an employee of
the Company, by granting to each outside director (upon joining the Board) stock
options to purchase 50,000 shares of Common Stock, at an exercise price equal to
the closing price of the Common Stock on the date of grant, with the options
vesting over a one year period in equal quarterly amounts. In addition, each
non-employee director receives an option grant to purchase 7,500 shares of
Common Stock for each year of service after the first year as a member of the
Board of Directors. Such options vest over a one year period in equal quarterly
amounts. In addition to the aforementioned option grants, directors may be
granted additional options at the discretion of the Board of Directors and the
Compensation Committee.

            During the year ended December 31, 2003 the Company paid CMH Capital
Management Corp ("CMH") a monthly fee of $17,500 in consideration for financial
advisory and consulting services rendered. Corey M. Horowitz, Chairman, Chief
Executive Officer, Chairman of the Board of Directors and a principal
stockholder of the Company, is the sole officer, director and stockholder of
CMH. In addition, in connection with such financial advisory and consulting
services, CMH was reimbursed for expenses during 2003 in the amount of $41,000,
including the allocable portion of rent for office space in New York City. In
December 2003, the Company employed Mr. Horowitz as Chairman and Chief Executive
Officer at which time CMH no longer provided financial and advisory services to
the Company. At the time of commencement of his employment as Chairman and Chief
Executive Officer in December 2003, the Company issued to Mr. Horowitz five (5)
year options to purchase an aggregate of 1,600,000 shares of common stock
(1,084,782 shares at an exercise price of .23 per share and options to purchase
515,218 shares at an exercise price of $.13 per share. In November 2004, the
Company entered into a two year employment agreement with Mr. Horowitz pursuant
to which he continued to serve as Chairman and Chief Executive Officer, and the
Company issued additional options to Mr. Horowitz to purchase 1,500,000 shares
of common stock. (See Item 10. "Executive Compensation - Employment Contracts,
Termination of Employment and Change-In-Control Arrangements" at page 24 hereof.

            In October 2001, the Company entered into a ten-year License and
Distribution Agreement (the "Agreement") with Falconstor Software, Inc.
("Falconstor"), an investor in the Company's private offering of securities
completed in October 2001. On May 30, 2003, as part of the Company's sale of its
software assets, the Company assigned its rights under the Agreement to the
purchaser of such assets (See Note H[3] to the Financial Statements).
Falconstore was a principal stockholder of the Company at the time of the
aforementioned transactions. In addition, two of the Company's principal
stockholders were also principal stockholders of Falconstor at the time of sale
the Company's software assets.

            In February 2003, the Company closed its principal offices in
Waltham, Massachusetts and moved its principal offices to space in New York City

            On November 18, 2003, the Company entered into an agreement (the

networking technologies from Merlot for a purchase price of $100,000 and
contingent future payments equal to 20% of the net income (as defined in the
Agreement) of the Company from the sale or licensing of the Patents after the
Company achieves $4.0 million of net income for each patent comprising the
Patent Portfolio ("Future Contingent Payments"). In addition, the Agreement
provided the Company with an option to terminate the Net Profit Payments, at any
time between January 1, 2007 through March 31, 2007, and from January 1 through
March 31 of each year thereafter, by making payments to Merlot in an amount
equal to the greater of (i) two times the payment due for the twelve month
period following the notice of termination or (ii) $3.0 million plus 10% for
each additional year starting January 1, 2008. On January 18, 2005, the Company
and Merlot entered into an amendment to the Agreement (the "Amendment") pursuant
to which the Company paid $500,000 to Merlot in consideration for the
restructuring of the Future Contingent Payments to Merlot from the licensing or
sale of the Patent Portfolio. The Amendment provides for future contingent
payments by the Company to Merlot of $1.0 million upon achievement of $25
million of Net Royalties (as defined), an additional $1.0 million upon
achievement of $50 million of Net Royalties and an additional $500,000 upon
achievement of $62.5 million of Net Royalties from licensing or sale of the

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Network-1 Security Solutions, Inc.



We have audited the accompanying balance sheets of Network-1 Security Solutions,
Inc. as of December 31, 2004 and 2003, and the related statements of operations,
stockholders' equity and cash flows for each of the years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements enumerated above present fairly, in all
material respects, the financial position of Network-1 Security Solutions, Inc.
as of December 31, 2004 and 2003, and the results of its operations and its cash
flows for each of the years then ended in conformity with accounting principles
generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004 AND 2003


NOTE A - THE COMPANY

[1]    Network-1 Security Solutions, Inc. (the "Company") is engaged in the
       acquisition, licensing and protection of its intellectual property and
       proprietary technologies. The Company owns six patents covering various
       telecommunications and data networking technologies (the "Patent
       Portfolio"). As part of its new business strategy following the
       acquisition of the Patent Portfolio in November 2003, the Company offers
       licenses to third parties for the technologies covered by its patents. In
       February 2004, the Company initiated its licensing efforts relating to
       its Patent Portfolio. As of December 31, 2004, the Company has not
       entered into any licensing arrangements with respect to its Patent
       Portfolio.

       Prior to the acquisition of the Patent Portfolio, the Company's business
       consisted of development, marketing, and licensing of network security
       software products designed to provide comprehensive security to computer
       networks. The Company also provided support, maintenance and training
       services related to its software products. In December 2002, the Company
       discontinued its software product line and associated operations, ceased
       its product development and eliminated its sales and marketing efforts
       and during May 2003, sold substantially all of its intellectual property
       related to its security software.

[2]    As reflected in the accompanying financial statements, the Company has
       incurred substantial losses and has experienced net cash outflows from
       operations. In 2004, the Company had no revenue from operations. The
       Company will continue to have operating losses for the foreseeable future
       until it is successful in licensing its patented technology. The Company
       is dependent upon debt and equity financing until it generates cash flows
       from operations. As discussed in Note D[2], the Company completed the
       first closing of a private placement of its securities in December 2004.
       As a result of such private placement, the Company has cash and cash
       equivalents of $2,177,000 as of December 31, 2004.

       Also, as discussed in Note L[1], in January 2005 the Company completed a
       second closing of the private placement of its equity securities and
       received a gross proceeds of $600,000. If necessary, the Company will
       take further action which it believes is required to sustain its
       operations for the next twelve months.


NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

[1]    CASH EQUIVALENTS:

       The Company considers all highly liquid short-term investments purchased
       with an original maturity of three months or less to be cash equivalents.

[2]    REVENUE RECOGNITION:

       License revenue is recognized upon delivery of software or delivery of a
       required software key. License revenue from distributors or resellers is
       recognized as the distributor or reseller delivers software or the
       required software key to end users or original equipment manufacturers.
       Service revenues consist of maintenance and training services. Annual
       renewable maintenance fees are a separate component of each contract, and
       are recognized ratably over the contract term. Revenue from advance
       license fees are deferred until they are earned pursuant to agreements.

                                                                             F-6

       The Company owns a Patent Portfolio that relates to various
       telecommunications and data networking technologies. The Company
       capitalizes the costs associated with acquisition, registration and
       maintenance of the patents and amortizes these assets over their
       remaining useful lives on a straight-line basis. Any further payments
       made to maintain or develop the patents would be capitalized and
       amortized over the balance of the useful life of the patents.

[4]    IMPAIRMENT OF LONG-LIVED ASSETS:

       In accordance with Statement of Financial Accounting Standards ("SFAS")
       No. 144, "Accounting for the Impairment or Disposal of Long-Lived
       Assets," intangible assets with finite lives are tested for impairment
       whenever events or circumstances indicate that the carrying amount may
       not be recoverable. Accordingly, the Company records impairment losses on
       long-lived assets used in operations or expected to be disposed of when
       indicators of impairment exist and the undiscounted cash flows expected
       to be derived from those assets are less than carrying amounts of those
       assets. During the years ended December 31, 2004 and 2003, there was no
       impairment to its patents.

[5]    INCOME TAXES:

       The Company utilizes the liability method of accounting for income taxes.
       Under such method, deferred tax assets and liabilities are recognized for
       the future tax consequences attributable to differences between the
       financial statement carrying amounts of existing assets and liabilities
       and their respective tax bases. Deferred tax assets and liabilities are
       measured using enacted tax rates in effect at the balance sheet date. The
       resulting asset or liability is adjusted to reflect enacted changes in
       tax law. Deferred tax assets are reduced, if necessary, by a valuation
       allowance when the likelihood of realization is not assured.

[6]    LOSS PER SHARE:

       Basic loss per share is calculated by dividing the net loss by the
       weighted average number of outstanding common shares during the year.
       Diluted per share data includes the dilutive effects of options, warrants
       and convertible securities. Potential common shares of 10,111,299 and
       11,495,493 at December 31, 2004 and 2003, respectively, are not included
       in the calculation of diluted loss per share because its effect will be
       anti-dilutive. Such potential common shares are options, warrants,
       convertible preferred stock and convertible notes.

[7]    USE OF ESTIMATES:

       The preparation of financial statements in conformity with accounting
       principles generally accepted in the United States of America requires
       management to make estimates and assumptions that affect the reported
       amounts of assets and liabilities and disclosure of contingent assets and
       liabilities at the date of the financial statements and the reported
       amounts of revenues and expenses during the reporting period. Actual
       results could differ from those estimates.

[8]    FINANCIAL INSTRUMENTS:

       The carrying amounts of cash and cash equivalents, accounts payable and
       accrued expenses approximate their fair value due to the short period to
       maturity of these instruments.

                                                                             F-7

[9]    STOCK-BASED COMPENSATION:

       The Company accounts for stock-based employee compensation under
       Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock
       Issued to Employees," and related interpretations. The Company has
       adopted the disclosure-only provisions of SFAS No. 123, "Accounting for
       Stock-Based Compensation;" and SFAS No. 148, "Accounting for Stock-Based
       Compensation - Transition and Disclosure," which was released in December
       2002 as an amendment of SFAS No. 123. The following table illustrates the
       effect on net loss and loss per share if the fair value-based method had
       been applied to all awards:

DECEMBER 31, 2004 AND 2003

NOTE B - SIGNIFICANT ACCOUNTING POLICIES  (CONTINUED)

[10]   RECENTLY ISSUED ACCOUNTING STANDARDS:

       In December 2004, the Financial Accounting Standards Board ("FASB")
       issued Statement of Financial Accounting Standards No. 123R, "Share-Based
       Payment" ("SFAS 123R"), which replaces SFAS No. 123, "Accounting for
       Stock-Based Compensation," and supersedes APB Opinion No. 25, "Accounting
       for Stock Issued to Employees." This statement requires all share-based
       payments to employees be recognized in the financial statements based on
       their fair values on the date of grant. The Company currently uses the
       intrinsic value method to measure compensation expense for stock-based
       awards which requires a pro forma net income and earnings per share
       presentation as if the Company had used a fair-value based method
       provided by SFAS 123 to measure stock-based compensation. The Company is
       required to adopt SFAS 123R in the first quarter of 2006. The Company is
       evaluating the requirements of SFAS 123R and expects that any future
       issuance of options could upon its adoption have a material impact on the
       Company's results of operations and earnings (loss) per share.

       In November of 2004, the FASB issued SFAS No. 151, "Inventory Costs,"
       which amends the guidance in ARB No. 43, Chapter 4, "Inventory Pricing,"
       to clarify the accounting for abnormal amounts of idle facility expense,
       freight, handling costs, and wasted material (spoilage). This statement
       requires that those items be recognized as current-period charges
       regardless of whether they meet the criterion of "so abnormal" as stated
       in ARB No. 43. Additionally, SFAS 151 requires allocation of fixed
       production overheads to the costs of conversion be based on the normal
       capacity of the production facilities. The Company is required to adopt
       the provision of SFAS No. 151 in the third quarter of 2006. The Company
       does not expect SFAS 151 to have a material impact on its results of
       operations or financial condition.

       In December of 2004, the FASB issued SFAS No. 153, "Exchanges of
       Nonmonetary Assets - An Amendment of APB Opinion No. 29 ("SFAS 153").
       SFAS 153 eliminates the exception for nonmonetary exchanges of similar
       productive assets and replaces it with a general exception for exchanges
       of nonmonetary assets that do not have commercial substance. SFAS 153 is
       effective for the fiscal periods beginning after June 15, 2005 and is
       required to be adopted by the Company in the first quarter of 2006. The
       Company does not expect that the adoption of SFAS 153 will have a
       material impact on the Company's results of operations or financial
       condition.

       Financial Accounting Standards Board Interpretation No. 46,
       "Consolidation of Variable Interest Entities" (FIN No. 46) was originally
       issued in January 2003 and was subsequently revised in December 2003. FIN
       No. 46 attempts to clarify the application of Accounting Research
       Bulletin No. 51, Consolidated Financial Statements, to certain entities
       in which equity investors do not have the characteristics of a
       controlling financial interest or do not have sufficient equity at risk
       for the entity to finance its activities without additional subordinated
       financial support. The Company does not believe that it has any
       involvement with variable interest entities that are required to be
       consolidated under FIN No. 46.

NOTE C - PATENTS

In November 2003, the Company acquired a portfolio of telecommunications and
data networking patents (six patents) from Merlot Communications, Inc. (the
"Seller") in which certain principal stockholders of the Company owned a
majority of the Seller's voting stock at the time of the transaction. The
purchase price for the Patent Portfolio was $100,000, paid in cash. The cash
price paid has been capitalized and is being amortized over the remaining useful
life of each patent. In addition, the Company has granted the Seller a
nonexclusive, royalty free, perpetual license for the term of each patent to use
the patents for the development, manufacture or sale of its own branded products
to end users. The Company had agreed to pay the Seller 20% of the net income, as
defined, after the first $4,000,000 of net income realized by the Company on a
per patent basis from the sale or
                                                                             F-9

licensing of the patents. The Company also has an option to terminate these
payments for each of the patents, commencing January 1, 2007 through March 31,
2007, and for each January 1 through March 31 period thereafter, by paying the
greater of: (i) two times the payment due for the 12 months immediately
following the notice of termination for each patent; or (ii) $3 million plus an
extra 10% for each additional year starting the fourth year after the closing of
the patent agreement for each patent. In January 2005, this agreement was
amended (see Note L[2]).

For the years ended December 31, 2004 and 2003, the Company has not derived any
income from sale or licensing of these patents.

NOTE D - STOCKHOLDERS' EQUITY

[1]    PREFERRED STOCK:

       In April 2004, the Company entered into an exchange agreement with the
       holders of all of the Company's outstanding shares of Series E ("Series
       E") and Series D ("Series D") convertible preferred stock to exchange
       2,483,508 shares of Series E for 6,208,770 shares of common stock and
       231,054 shares of Series D for 489,348 shares of common stock. As an
       inducement for agreeing to such conversion, the holders of the Series E
       and Series D received 1.25 times the number of shares of common stock
       that each preferred stockholder would have otherwise received upon
       conversion. The holders of preferred stock participating in the exchange
       included, among others, CMH Capital Management Corp. ("CMH") (1,084,935
       of Series E shares), the wife of Corey M. Horowitz, CEO of the Company
       (35,377 of Series E shares) and other principal stockholders of the
       Company (990,552 of Series E shares and 209,125 of Series D shares). Upon
       closing of the exchange agreement, there were no outstanding shares of
       preferred stock. Corey M. Horowitz, Chairman and Chief Executive Officer
       and a principal stockholder of the Company, is the sole owner and officer
       of CMH.

[2]    PRIVATE PLACEMENT:

       On December 21, 2004, the Company completed a private placement of
       2,085,000 shares of common stock and three-year warrants to purchase
       1,563,750 shares of common stock (warrants to purchase 1,042,500 shares
       of common stock at an exercise price of $1.25 and warrants to purchase
       521,250 shares of common stock at an exercise price of $1.75) for an
       aggregate purchase price of $2,035,000, net of $50,000 issuance costs.
       The Company issued to a finder, warrants to purchase 50,000 shares of
       common stock at an exercise price of $1.00 expiring in December 2009. As
       part of the private placement, the Company agreed to file a registration
       statement on or before June 21, 2005, to register the common stock and
       the shares issuable upon exercise of the warrants.

       In connection with the private placement and anti-dilutive provisions for
       the warrants previously issued to Falconstor, the Company issued warrants
       to purchase 128,713 additional shares of common stock at an exercise
       price of $1.01 expiring in October 2006 (see Note H[3]). The associated
       expense of $147,000, as an imputed dividend, is based on the fair value
       of these warrants using the Black-Scholes model utilizing the risk-free
       interest rate of 3.01%, life of 2 years, volatility of 270% and dividend
       yield of 0% and is included in the accompanying statement of operations
       for the year ended December 31, 2004.

NOTE D - STOCKHOLDERS' EQUITY  (CONTINUED)

[3]    STOCK OPTIONS:

       During 1996, the Board of Directors and stockholders approved the
       adoption of the 1996 Stock Option Plan (the "1996 Plan"). The 1996 Plan,
       as amended, provides for the granting of both incentive and non-qualified
       options to purchase common stock of the Company. A total of 4,000,000
       shares are provided for under the 1996 Plan.

       The term of options granted under the 1996 Plan may not exceed ten years
       (five years in the case of an incentive stock option granted to an
       employee/director owning more than 10% of the voting stock of the
       Company) ("10% stockholder"). The option price for incentive stock
       options cannot be less than 100% of the fair market value of the shares
       of common stock at the time the option is granted (110% for a 10%
       stockholder). Option terms and vesting periods are set by the
       Compensation Committee in its discretion.

(a)    Includes five-year options to purchase 1,600,000 shares of the Company's
       common stock issued to Corey M. Horowitz, Chairman and Chief Executive
       Officer, in connection with an agreement in December 2003 (see Note I[1])
       as follows: (i) incentive stock options to purchase 1,084,782 shares of
       common stock, at an exercise price of $0.23 per share, of which 434,782
       options vested immediately, 250,000 options vested on December 22, 2004
       and 200,000 options each vest on December 22, 2005 and December 22, 2006
       and (ii) non-qualified stock options to purchase 515,218 shares of common
       stock, at an exercise price of $0.13 per share, which vested immediately.
       The Company recognized $41,000 of expense in 2003 related to the 515,218
       options representing the difference between the exercise price of the
       options and the market price on the date of grant.

(b)    Includes ten-year options to purchase 1,200,000 shares of the Company's
       common stock at an exercise price of $1.65 per share issued in March
       2002, in connection with a two-year employment agreement with Richard J.
       Kosinski, as Chief Executive Officer and President. In July 2003, all of
       these options issued were forfeited in connection with the settlement of
       a lawsuit by Mr. Kosinski against the Company.

(c)    Includes options issued to Mr. Horowitz with respect to his two-year
       employment agreement entered into with the Company in November 2004, to
       purchase an aggregate of 1,500,000 shares of common stock consisting of
       (i) ten-year non-qualified options to purchase 1,100,000 shares at an
       exercise price of $0.25 per share fully vested on the date of grant and
       (ii) five-year incentive stock options to purchase 400,000 shares at an
       exercise price of $0.68 per share which vested 50% on the date of grant
       and 50% one year thereafter, subject to acceleration upon a change of
       control (see Note I[3]). The Company recognized $407,000 of expense in
       2004 related to the 1,100,000 options representing the difference between
       the exercise price of the option and the market price on the date of
       grant. The Company did not recognize compensation expense for 400,000
       options as the exercise price exceeded the market price on the date of
       grant.

                                                                            F-11

       On April 18, 2002, in consideration of additional consulting and
       financial advisory services, the Company issued to CMH an option to
       purchase 750,000 shares of the common stock at an exercise price of $1.20
       per share, which was the market price of the Company's common stock on
       the date of issuance. The options vest over a three-year period in equal
       amounts of 250,000 per year beginning April 18, 2003. In addition, the
       options shall vest in full in the event of a "change of control" or in
       the event that the closing price of the Company's common stock reaches a
       minimum of $3.50 per share for 20 consecutive trading days. These options
       are treated as contingent options and were originally priced in the
       quarter ended June 30, 2002 at $416,000. Subsequently, they are revalued
       at each balance sheet date. On April 18, 2003, 250,000 of these options
       vested, having a fair value of $5,000. Accordingly, $5,000 was
       reallocated to additional paid-in capital with a corresponding reduction
       to the liability. On April 18, 2004, 250,000 of these options vested
       having a fair value of $51,000. Accordingly, $51,000 was reallocated to
       additional paid-in-capital with a corresponding reduction to the
       liability. The options to purchase the remaining 250,000 shares continue
       to be treated as contingent options and are valued utilizing the
       Black-Scholes option-pricing model at each balance sheet date. At
       December 31, 2004, the 250,000 unvested options were valued at $294,000.
       Any increase or decrease in the valuation has been reflected as an
       addition or reduction of general and administrative expenses at each
       balance sheet date.


                                                                            F-12

The Company places its cash investments in high quality financial institutions
insured by the Federal Deposit Insurance Corporation ("FDIC"). At December 31,
2004, the Company maintained cash balances of $2,077,000 in excess of FDIC
limits.


NOTE H - RELATED PARTY TRANSACTIONS

[1]    In November 2004, the Company entered into a two-year employment
       agreement with Corey M. Horowitz to continue to serve as Chairman and
       Chief Executive Officer at a base salary of $250,000 for the first year
       and $275,000 for the second year (see Note I[3]).

       During the year ended December 31, 2003, the Company paid CMH a monthly
       fee of $17,500 in consideration for financial advisory and consulting
       services rendered. Corey M. Horowitz, Chairman, Chief Executive Officer,
       and a principal stockholder of the Company, is the sole officer, director
       and stockholder of CMH. In addition, in connection with such financial
       advisory and consulting services, CMH was reimbursed for expenses in 2003
       in the amount of $41,000, including the allocated portion of rent for
       office space in New York City. In December 2003, the Company employed Mr.
       Horowitz as Chief Executive Officer at an annual salary of $210,000 at
       which time CMH no longer provided financial and advisory services to the
       Company. In addition, Mr. Horowitz received options to purchase 1,600,000
       shares of common stock (see Note D[3](a)).

[2]    In April 2004, the Company entered into an exchange agreement with the
       holders of all of the Company's outstanding shares of Series E and Series
       D convertible preferred stock to convert 2,483,508 shares of Series E
       into 6,208,770 shares of common stock and 231,054 shares of Series D into
       489,348 shares of common stock. As an inducement for agreeing to such
       conversion, the holders of the Series E and Series D received 1.25 times
       the number of shares of common stock that each preferred stockholder
       would have otherwise received upon conversion. The holders of preferred
       stock participating in the exchange included, among others, CMH
       (1,084,935 of Series E shares), the wife of Corey M. Horowitz (35,377 of
       Series E shares) and other principal stockholders of the Company (990,552
       of Series E shares and 209,125 of Series D shares). Upon closing of the
       agreement, there were no outstanding shares of preferred stock.

[3]    The Company entered into a ten-year License and Distribution Agreement
       with Falconstor (the "Falconstor Agreement"), an investor in the
       Company's financing in 2001. This agreement required Falconstor to pay
       royalties after utilizing a non-refundable advance paid by them to the
       Company as a credit. On May 30, 2003, as part of the Company's sale of a

       private placement (100,000 shares of common stock and warrants to
       purchase 75,000 shares of common stock) is a director of the Company.

NOTE I - EMPLOYMENT ARRANGEMENTS AND OTHER AGREEMENTS

[1]    On December 22, 2003, the Company entered into an arrangement with Corey
       M. Horowitz to serve as the Chairman and Chief Executive Officer of the
       Company. At the time, the Company agreed to pay a salary of $210,000. In
       addition, Mr. Horowitz received options to purchase 1,600,000 shares of
       common stock (see Note D[3](a)).

[2]    In January 2004, the Company entered into an agreement with an individual
       to serve as the Company's Chief Financial Officer ("CFO"). The agreement
       expired on December 31, 2004 and provided for a base salary of $5,500 per
       month for the period January 22, 2004 through April 30, 2004, $4,500 per
       month for the period May 1, 2004 through August 31, 2004 and $3,500 per
       month from September 1, 2004 through December 31, 2004. In connection
       with his agreement, the CFO received options to purchase 50,000 shares of
       common stock of the Company at $0.35 per share under the Company's stock
       option plan, at the fair market value of the shares on the date of the
       grant. 20,000 of these options vested immediately and the balance vested
       on a monthly basis through December 31, 2004. The Company is in process
       of negotiating a new agreement with the CFO.

[3]    On November 26, 2004, the Company entered into an employment agreement
       with Corey M. Horowitz pursuant to which he agreed to continue to serve
       as Chairman and Chief Executive Officer of the Company for a two-year
       term at an annual base salary of $250,000 for the first year and $275,000
       for the second year. Mr. Horowitz was also issued options to purchase an
       aggregate of 1,500,000 shares of the Company's common stock consisting of
       (i) a ten (10) year fully vested option to purchase 1,100,000 shares at
       an exercise price of $0.25 per share, and (ii) a five-year option to
       purchase 400,000 shares at an exercise price of $0.68 per share which
       vested 50% on the date of grant and 50% one year thereafter, subject to
       acceleration upon a change of control (see Note D[3](c)). In addition,
       Mr. Horowitz will receive a bonus of 5% of the Company's royalties or
       other payments received from licensing its patents. This bonus will
       continue to be paid to Mr. Horowitz for a period of five (5) years
       following the term of the employment agreement with respect to licenses
       entered into by the Company during the term of the employment agreement,
       provided that he has not been terminated by the Company "for cause" or by
       Mr. Horowitz himself without "good reason". Mr. Horowitz shall receive
       severance equal to 12 months base salary in the event his employment is
       terminated "without cause" or by Mr. Horowitz for "good reason". Mr.
       Horowitz was also granted certain anti-dilution rights which provide that
       if at any time during the period ending December 31, 2005, in the event
       that the Company completes an offering of its common stock or any
       securities convertible or exercisable into common stock, he will receive,
       at the same price as the securities issued in the financing, such number
       of additional stock options so that he maintains the same ownership
       percentage of (20.11%) of the Company based upon options and warrants
       owned by him and CMH (exclusive of his ownership of shares of common
       stock) as he owned as of November 26, 2004. As a result of the closings
       of the private placement on December 31, 2004 and January 13, 2005 and in
       accordance with the anti-dilution protection afforded to Mr. Horowitz in
       his employment agreement, Mr. Horowitz earned
                                                                            F-16

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004 AND 2003


NOTE I - EMPLOYMENT ARRANGEMENTS AND OTHER AGREEMENTS  (CONTINUED)

[3]    (continued)

       seven year options to purchase an aggregate of 960,197 shares at an
       exercise price of $1.18 per share, consisting of an option to purchase
       745,628 shares as a result of first closing on December 21, 2004 and an
       option to purchase 214,569 shares as a result of second closing of the
       private placement on January 13, 2005 (see Notes D[3](e) and L[3]).


NOTE J - GAIN ON SALE OF ASSETS

On May 30, 2003, the Company completed the sale of its CyberwallPlus technology
and related intellectual property and assignment of its rights under the
Falconstar Agreement for aggregate proceeds of $415,000. The carrying value of
these assets was written down to zero in the third quarter of 2002. The $415,000
is reflected as "Gain on Sale of Assets" in the statements of operations.


NOTE K - LITIGATION

In March 2004, PowerDsine Inc. ("PowerDsine") commenced an action against the
Company in the United District Court, Southern District of New York, seeking a
declaratory judgment that the Company's patent (U.S. Patent No. 6,218,930)
covering the remote delivery of power over Ethernet (the "Remote Power Patent")
is not infringed by PowerDsine and/or its customers. PowerDsine further seeks an
order permanently enjoining the Company (i) from making any claims to any person
or entity that PowerDsine's products infringe the Remote Power Patent or
contribute to infringement of the patent, (ii) from interfering with or
threatening to interfere with the importation, sale, license or use of
PowerDsine's power over Ethernet components or products, and (iii) from
instituting or prosecuting any lawsuit or proceeding placing at issue the right
of PowerDsine, its customers, licensees, successors, or assigns to import, use
or sell PowerDsine's power over Ethernet components or products. The Company
believes its Remote Power Patent is valid and has meritorious defenses to the
action. On December 1, 2004, the Company moved to dismiss the declaratory
judgment action asserting, among other things, that there is no actual case or
controversy because PowerDsine did not have reasonable apprehension of suit at
the time the case was filed, and therefore the court lacks jurisdiction over the
matter. On January 21, 2005, the Company's motion to dismiss was denied. The
Company intends to vigorously defend the action and take whatever actions are
necessary to protect its intellectual property. In the event, however, that the
Court grants the declaratory judgment and the Company's patent is determined to
be invalid, such a determination would have a material adverse effect on the
Company.


NOTE L - SUBSEQUENT EVENTS

[1]    On January 13, 2005, the Company completed a second closing with respect
       to a private placement of securities (see Note D[2]), which consisted of
       an additional 600,000 shares of common stock and warrants to purchase an
       additional 450,000 shares of common stock for an aggregate purchase price
       of $600,000.

[2]    On January 18, 2005, the Company and Merlot Communications, Inc.
       ("Merlot") entered into an amendment to the Patent Purchase Agreement
       (the "Amendment") pursuant to which the Company paid $500,000 to Merlot
       in consideration for the restructuring of future contingent payments to
       Merlot from the licensing or sale of the Patents. The Amendment provides
       for future contingent payments by the Company to Merlot of $1.0 million
       upon achievement of $25 million of Net Royalties (as defined), an
       additional $1.0 million upon achievement of $50 million of Net Royalties
       and an additional $500,000 upon achievement of $62.5 million of Net
       Royalties from licensing or sale of the patents acquired from Merlot.
       Certain principal officers/directors stockholders of the Company owned a
       majority of the outstanding voting stock of Merlot and were also
       directors of Merlot at the time of the Amendment.


                                                                            F-17

       of $1.18 per share, as a result of the Company's completion of a private
