ITEM 1. DESCRIPTION OF BUSINESS.

        BACKGROUND

During the period June 1995 until December 2002, Network-1 Security Solutions,
Inc. (the "Company") developed, marketed, licensed and supported security
software products designed to prevent unauthorized access to information
residing on an enterprise's data network. In December 2002, the Company
discontinued offering its security software product line as it was unable to
achieve sufficient product revenue to support the expenses of such operations.
Thereafter, the Company sought a new business either through a merger or other
strategic transaction. In May 2003, the Company completed the sale of its
security software technology and related intellectual property to an
unaffiliated third party for $415,000. In November 2003, the Company acquired a
portfolio of telecommunications and data networking patents. As part of its new
business, the Company is pursuing licensing opportunities related to the
technologies covered by the patent portfolio. Provided below is a description of
the Company's current business and its business activities during the year ended
December 31, 2003.

        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 is pursuing 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 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

                                       2
<PAGE>

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.

        THE PATENTS

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

                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;

                U.S. Patent No. 6,218,930: Apparatus and method for remotely
powering access equipment over a 10/100 switched Ethernet network; 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 and its ability to protect its intellectual property rights. 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 judgement 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 remote delivery of power
over Ethernet cables (the "Remote Power Patent"). As of March 31, 2004, the
Company transmitted letters to approximately 80 companies offering licenses to
the Remote Power Patent. To date the Company has not entered into any license
agreements with third parties with respect to its Remote Power Patent.

        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 critical 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.

        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 remotely powering devices
on an Ethernet network. 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.

        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, 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 such as
wireless access point, 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.

        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 be PoE
enabled in 2004.

                                       4
<PAGE>

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 manufacture 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
will 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. In
addition, In-State/MDR also estimated that units sold will rise from 18 million
to 75 million in 2006, which suggests that the cost of deploying wireless will
continue to fall as demand for wireless technologies continues to grow.

        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.

        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 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 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.

                                       5
<PAGE>

        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, Wireless
Internet Service Providers (WISPs), 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. As of March 31, 2004,
the Company transmitted letters to approximately 80 companies offering licenses
to the Remote Power Patent.

        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, 2004, the Company had one employee and one consultant.

        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, NO REVENUE FROM CURRENT OPERATIONS AND WE
MAY NOT BE ABLE TO CONTINUE OUR OPERATIONS IN THE FUTURE.

        We have incurred substantial operating losses since our inception, which
has resulted in an accumulated deficit of $(41,036,000) as of December 31, 2003.
For the years ended December 31, 2003 and 2002, we incurred net losses of
$(614,000) and $(5,905,000), respectively. Since December 31, 2003, we have
continued to incur operating losses. We have financed our operations primarily
from the balance of funds from sales of equity and convertible debt securities
as well as the sale of our CyberWall PLUS security software technology in May
2003. Since December 2002, when we discontinued our offering of security
software products, we have not had material revenue from operations. We may not
have sufficient funds to continue our operations if we are unable to generate
sufficient revenue from our new business of licensing our telecommunications and
data networking patents.

        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 at least September 2004. There can be no assurance, however,
that such funds will not be expended 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 2004. We are
currently pursuing licensing opportunities for our patented technologies.
However, to date we have not entered into any such licensing arrangements. In
addition, even if we consummate licensing arrangements, such agreements may not
result in sufficient cash to support our operations or achieve material revenues
or profitability. Since we do not anticipate material revenues from our
licensing business in the near term, we intend to make efforts to raise capital
during the second or third quarter of 2004 to continue to fund our operations.
We have no current arrangements with respect to any additional financing.
Consequently, there can be no assurance that any additional financing will be
available to the Company when needed, on commercially reasonable terms or at
all. Our 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 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.

                                       7
<PAGE>

        WE RECENTLY ENTERED A NEW LICENSING BUSINESS AND 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 rapidly changing
technologies in a highly specialized and competitive market. We may not be able
to achieve revenues 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. 6,212,930). To
date, we have not entered into any licensing agreements with third parties with
respect to our 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 unlikely to produce a stable or predictable
stream of revenue in the foreseeable future. Furthermore, the success of our
licensing efforts may depend upon the strength of our intellectual property
rights.

        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 (U.S. Patent No. 6,218,930) 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 contributes 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. We intend
to vigorously defend the action and take whatever actions are necessary to
protect our intellectual property. In the event, however, that the Court granted
the declaratory judgment and our 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.

                                       8
<PAGE>

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

        The telecommunications and data networking licensing 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, our current and potential competitors may develop technologies that
may be more effective than our proprietary technologies or that render our
technologies less marketable or obsolete. We may not be able to compete
successfully.

        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.

        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 trade secret law, 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.

                                       9
<PAGE>

        ANY LITIGATION TO PROTECT OUR INTELLECTUAL PROPERTY OR ANY THIRD PARTY
CLAIMS OF INFRINGEMENT COULD INVOLVE SUBSTANTIAL TIME AND MONEY AND COULD HAVE A
MATERIAL ADVERSE EFFECT ON OUR BUSINESS.

        Our success depends on our ability to protect our intellectual property
rights. Accordingly, we may be subject to third-party claims seeking to
invalidate our patents. 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 competitors with substantially greater financial
resources. 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.

        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. Mr. Horowitz does not currently have an employment agreement with the
Company and serves as an employee-at-will. The loss of the services of Mr.
Horowitz could have a material adverse effect on our business and prospects.

        DELISTING OF OUR SECURITIES FROM NASDAQ; RISKS RELATING TO LOW-PRICED
STOCKS.

        On March 26, 2003 our common stock was delisted from The Nasdaq Stock
Market's SmallCap Market. As a result of the delisting, an investor could find
it more difficult to dispose of or to obtain accurate quotations as to the
market value of our common stock. Our common stock currently trades on the
over-the-counter market in the "pink sheets."

        In addition, since our common stock has been delisted from trading on
Nasdaq and 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 exceptions. The SEC regulations would 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. As a result of the delisting of our Common
Stock from Nasdaq, investors may find it more difficult to obtain timely and
accurate quotes and execute trades in our common stock.

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

        As of March 31, 2004, there are outstanding (i) options and warrants to
purchase an aggregate of 5,841,860 shares of our common stock at exercise prices
ranging from $.12 to $10.13, and (ii) 727,630 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, your 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
$2,700 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 any claims to any person or entity that PowerDsine's
products infringe the Remote Power Patent or contributes 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 has meritorious defenses to the
action. The Company intends to vigorously defend the action and take whatever
actions are necessary to protect it's intellectual property. In the event,
however, that

                                       11
<PAGE>

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.

        Additional Litigation

        In January 2003, Richard J. Kosinski, former Chief Executive Officer,
President and a director of the Company, and Murray P. Fish, former Chief
Financial Officer and a director of the Company, commenced lawsuits against the
Company in the Commonwealth of Massachusetts, County of Essex, Superior Court,
seeking severance and bonus compensation and other benefits allegedly due them
in the aggregate amount of $400,000. In June 2003, the Company entered into a
settlement agreement with Mr. Kosinski pursuant to which the Company paid Mr.
Kosinski the sum of $127,000 in full settlement of all claims asserted by him in
the litigation. In addition, as part of the settlement, Mr. Kosinski agreed to
forfeit options to purchase 1,200,000 shares of the Company's Common Stock. In
February 2004, the Company reached an agreement in principal with Mr. Fish
pursuant to which the Company has agreed to pay Mr. Fish the sum of $55,000 in
full settlement of all claims asserted by him in the litigation.

will be at the discretion of the Board of Directors and will depend upon a
variety of factors, including future earnings, if any, operations, capital
requirements, the general financial condition of the Company, the preferences of
any series of Preferred Stock, the general business conditions and future
contractual restrictions on payment of dividends, if any.

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

        From June 1995 until December 2002, the Company licensed and supported a
suite of security software products designed to prevent unauthorized access to
critical information residing on networked servers, desktops and laptops. In
December 2002, in order to preserve cash as the Company sought a merger or other
strategic transaction, the Company discontinued its products offerings, as
operating expenses continued to exceed product revenues. In May 2003, the
Company completed the sale of its security software technology and related
intellectual property to an unaffilitated foreign corporation for an aggregate
consideration of $415,000. As a part of this sale, the Company also assigned its
rights under its Distribution and License Agreement with

                                       14
<PAGE>

FalconStor Software, Inc. ("FalconStor") pursuant to which FalconStor had the
right to distribute the Company's software product offerings in its indirect and
OEM channels.

        On November 18, 2003, the Company acquired the Patent Portfolio from
Merlot Communications, Inc., a broadband communications solutions provider. As
part of its new business, the Company is pursuing licensing opportunities
related to the technologies covered by the Patent Portfolio. After reviewing
numerous opportunities, the Company's Board of Directors decided that the
acquisition of the Patent Portfolio and the pursuit of licensing opportunities
related thereto was the most attractive available alternative for its
shareholders.

        The Patent Portfolio consists of six 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 power over Ethernet networks. The consideration paid by the Company to
Merlot Communications, Inc. ("Merlot") for the acquisition of the Patent
Portfolio consisted of a cash payment of $100,000 and contingent future payments
equal to 20% of the net income (as defined in the acquisition agreement) of the
Company from the sale or licensing of the Patent Portfolio after the Company
achieves $4.0 million of net income from each patent comprising the Patent
Portfolio ("Net Profit Payments"). The Company has 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. Wheatley Partners
II, L.P. and its affiliates and related parties (the "Wheatley Parties"), who
are principal stockholders of the Company, owned a majority of the outstanding
voting stock of Merlot at the time of the Company's acquisition of the Patent
Portfolio. The Wheatley Parties did not participate in the negotiation or the
approval of the patent acquisition transaction by Merlot or the Company.

        As of the date hereof, the Company has not entered into any license
arrangements with respect to the Patent Portfolio, although it is pursuing 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 such licensing arrangements
with third parties.

        To date the Company has incurred significant losses and at December 31,
2003, had an accumulated deficit of $(41,036,000). At March 31, 2004, the
Company had approximately $600,000 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 2004, 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:

        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. Training revenues are recognized as such services are performed.
Revenue from advance license fees are deferred until they are earned pursuant to
the agreements.

        Software development costs:

        Costs to maintain developed programs and development costs incurred to
establish the technological feasibility of computer software are expensed as
incurred. The Company capitalized costs incurred in producing computer software
after technological feasibility of the software has been established through the
date that the software is ready for general release to customers. Such costs are
amortized based on current and estimated future revenue of each product with an
annual minimum equal to the straight-line amortization over the remaining
estimated economic life of the product. The Company estimates the economic life
of its software to be three years. At each balance sheet date, the unamortized
capitalized software costs of each product are compared with the estimated net
realizable value of that product and any excess capitalized costs are written-
off.

        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. During the year ended December 31, 2002, the Company recorded an
impairment charge related to its network security software of approximately
$401,000, which has been included in amortization of software development costs.
Subsequently, in May 2003, the Company sold its network security software (see
Note A). The Company also reduced the carrying value of its fixed assets to
their net realizable amount (see Note B[6]).

                                       16
<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.

        RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS:

        See Note B[13] on page F-10 to the Financial Statements.

        RESULTS OF OPERATIONS

        YEAR ENDED DECEMBER 31, 2003 COMPARED TO YEAR ENDED DECEMBER 31, 2002.

        Revenues decreased by $374,000 or 63%, from $592,000 for the year ended
December 31, 2002 ("2002") to $ 218,000 for the year ended December 31, 2003
("2003"). Revenues during 2003 consisted of $130,000 related to the recognition
of deferred revenue with respect to the FalconStor license agreement and $88,000
of revenues were related to the amortization of deferred maintenance revenues
from customers who had elected to purchase maintenance and support contracts in
earlier periods.

        The cost of revenues during 2003 was $51,000. This cost relates to one
employee who provided services under the Company's maintenance and support
contracts. Amortization of software development costs decreased by $741,000 or
100%, from 2002 to 2003. Cost of licenses consists of software media (disks),
documentation, product packaging, production costs and product royalties. Cost
of licenses decreased by $15,000 or 100% from 2002 to 2003. Cost of services
consisted of salaries, benefits and overhead associated with the technical
support of maintenance contracts. Cost of services decreased by $196,000 or 65%,
from 2002 to 2003. The decrease in the cost of revenue is directly a result of
the Company's decision to discontinue its software product line in December
2002.

        Gross profit was $167,000 for 2003 compared to a gross loss of $ 311,000
for 2002.

        Product development costs consists of salaries, benefits, bonuses,
travel and related costs of the Company's product development personnel,
including consulting fees and the costs of computer equipment used in product
and technology development. Product development expenses were $1,599,000 for
2002. The Company made no expenditures on product development in 2003.

        Sales and marketing expenses consist primarily of salaries, including
commissions, benefits, bonuses, travel, advertising, public relations,
consultants and trade shows. Sales and marketing expenses were $1,831,000 in
2002. The Company had no sales and marketing expenses in 2003 as a result of its
decision to discontinue its software product line in December 2002.

                                       17
<PAGE>

        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 decreased by
$1,021,000 or 46%, from $2,229,000 in 2002 to $1,208,000 in 2003. The decrease
in general and administrative expenses was primarily due to substantial
reduction in employees following the discontinuance of the Company's software
business in December 2002.

        Interest income decreased by $53,000 or 82% from $65,000 in 2002 to
$12,000 in 2003 primarily due to a decrease in funds invested in short term
instruments and reduced interest rates.

        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 is included as "Gain on Sale of Assets" in the statements of
operations.

        No provision for or benefit from federal, state or foreign income taxes
was recorded for 2002 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 decreased by $5,578,00 or
92%, from $5,905,000 for 2002 to $614,000 for 2003.

        LIQUIDITY AND CAPITAL RESOURCES

        At December 31, 2003, the Company had $984,000 of cash and cash
equivalents and working capital of $472,000. The Company has financed its
operations primarily through sales of equity and debt securities, and the sale
of its security software technology in May 2003. Net cash used in operating
activities was $4,927,000 in 2002 and $1,360,000 in 2003. Net cash used in
operating activities for 2003 was primarily attributable to the net loss of
$614,000, a decrease in accounts payable, accrued expenses and other current
liabilities of $205,000 and the recognition of deferred revenue of $218,000.

        Net cash used in investing activities during 2003 was financed with the
remaining funds raised in the October 2001 financing of $6,765,000 and $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.

        The Company anticipates, based on currently proposed plans and
assumptions, relating to its operations that its cash balance of approximately
$600,000 as of March 31, 2004 will more likely than not be sufficient to satisfy
the Company's operations and capital requirements until September 2004. 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

                                       18
<PAGE>

expenses, difficulties, delays or otherwise), the Company may have insufficient
funds to support its operations prior to September 2004. 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. Since
the Company does not anticipate material revenues from its licensing business in
the near term, the Company currently intends to make efforts to raise capital
during the second or third quarter of 2004. The Company has no current
arrangements with respect to any additional financing. Consequently, there can
be no assurance that any additional financing will be available to the Company
when needed, on commercially reasonable terms or at all. 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.

        The financial statements required hereby are located on pages F-1
through F-20 which follow Part III.

ITEM 8. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE.

        None.

ITEM 8A. CONTROLS AND PROCEDURES.

        (a) Evaluation of Disclosure Controls and Procedures.

        The Company's Chief Executive Officer and Chief Financial Officer have
reviewed the disclosure controls and procedures of the Company as of the end of
the period covered by this Annual Report on Form 10-KSB. Based upon this review,
these officers concluded that, as of the end of the period covered by this

LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS

        The Company's Certificate of Incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Delaware law provides
that directors of a corporation will not be personally liable for monetary
damages for breach of their fiduciary duties as directors, except for liability
(i) for any breach of their duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for unlawful
payments

                                       21
<PAGE>

of dividends or unlawful stock repurchases or redemptions as provided in Section
174 of the Delaware General Corporation Law or (iv) for any transaction from
which the director derived an improper personal benefit. The Company's Bylaws
provide that the Company shall indemnify its directors, officers, employees and
agents to the fullest extent permitted by law. The Company's Bylaws also permit
the Company to secure insurance on behalf of any officer, director, employee or
other agent for any liability arising out of his or her actions in such
capacity. The Company currently maintains liability insurance for its officers
and directors. At present, there is no pending material litigation or proceeding
involving any director, officer, employee or agent of the Company where
indemnification will be required or permitted. The Company is not aware of any
threatened litigation or proceeding that might result in a material claim for
such indemnification.

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 between 25,000 - 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 5,000 - 25,000 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.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Exchange Act requires the Company's executive
officers, directors, and persons who own more than 10% of the Company's
outstanding Common Stock to file initial reports of ownership and changes in
ownership with the Securities and Exchange Commission. Officers, directors and
greater than 10% stockholders are required by Commission regulations to furnish
the Company with copies of all Section 16(a) forms they file. The Company
believes that its executive officers, directors, and greater than 10%
stockholders complied during the year ended December 31, 2003.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        From June 2001 until December 2003 the Company paid CMH Capital
Management Corp ("CMH") a monthly fee of $17,500 and issued to CMH warrants to
purchase an aggregate of 1,300,000 shares of Common Stock (at exercise prices
ranging from $.70 per share to $1.48 per share) 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 2002 and 2003 in the amount of
$50,000 and $41,000, respectively, 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.

        In February 2003, the Company closed its principal offices in Waltham,
Massachusetts and moved its principal offices to space in New York City occupied
by CMH. Network-1 pays rent on a month to month basis of $2,700 per month for
its principal offices in New York City.

        During 2002, Edward James was paid consulting fees of $68,164 by the
Company. In December 2002 Mr. James became a director of the Company and was
elected interim Chief Executive Officer and Chief Financial Officer in January
2003. From January 2003 until January 1, 2004, Mr. James was paid $12,500 per
month for his services as interim Chief Executive Officer and Chief Financial
Officer.

        On November 18, 2003, the Company acquired six patents relating to
various telecommunications and data networking technologies from Merlot
Communications, Inc. ("Merlot"), a broadband communications solutions provider,
for a purchase price of $100,000 and contingent future payments equal to 20% of
the net income (as defined in the acquisition agreement) of the Company from the
sale or licensing of the Patent Portfolio after the Company achieves $4.0
million of net income for each patent comprising the Patent Portfolio ("Net
Profit Payments"). The Company has 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. Wheatley Partners,
II, L.P. and its affiliates and related parties (the "Wheatley Parties"), who
are principal stockholders of the Company, also owned a majority of the
outstanding voting stock of Merlot at the time of the transaction. The Wheatley
Parties

                                       29

did not participate in the negotiation or the approval of the patent acquisition
transaction by Merlot or the Company.

        On April 13, 2004, the Company as part of a recapitalization entered
into an exchange agreement with each of its outstanding holders of preferred
stock pursuant to which such holders exchanged an aggregate of 2,714,562 shares

INDEPENDENT AUDITORS' REPORT

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


We have audited the accompanying balance sheets of Network-1 Security Solutions,
Inc. (the "Company") as of December 31, 2003 and 2002 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 auditing standards generally accepted
in the United States of America. 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, 2003 and 2002 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.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As more fully described in Note A[2],
the Company has incurred a net loss during 2003 and has a substantial
accumulated deficit, and needs to obtain additional capital. These conditions
raise substantial doubt about the Company's ability to continue as a going
concern. Management's plans in regard to these matters are also described in
Note A[2]. The financial statements do not include any adjustments that may
result from the outcome of this uncertainty.

NETWORK-1 SECURITY SOLUTIONS, INC.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2003 AND 2002

NOTE A - THE COMPANY

[1]    BUSINESS:

       Network-1 Security Solutions, Inc. (the "Company") developed, marketed,
       licensed and supported its proprietary network security software products
       designed to provide comprehensive security to computer networks. The
       Company also provided maintenance and training services.

       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. Through a series of layoffs, the Company
       has reduced its workforce to a current level of two employees. The
       Company has closed its various offices upon termination of leases during
       2002 and 2003. In February 2003, the Company closed its principal office
       in Waltham, Massachusetts and moved its principal offices to space in New
       York City in offices occupied by CMH Capital Management Corp. ("CMH") (a
       company owned by the Chairman and CEO). The Company reimburses CMH for
       rent in the amount of $2,700 per month on a month-to-month basis (see
       Note G[1]).

       As part of its new business strategy, in November 2003, the Company
       acquired a portfolio of telecommunications and data networking patents
       (the "Patent Portfolio") and is pursuing licensing opportunities related
       to the technologies covered by the Patent Portfolio. As of December 31,
       2003, the Company has not entered into any license arrangements with
       respect to the Patent Portfolio. However, it is pursuing such
       arrangements with third parties.

[2]    GOING CONCERN:

       The Company has incurred substantial net losses from operations during
       2003. The Company as of December 31, 2003 has cash and cash equivalents
       of $984,000 and currently is not generating revenues to support its
       operations. The Company has been dependent upon capital raised through
       both public and private placement of equity to finance its business
       operations. This raises substantial doubt about the Company's ability to
       continue as a going concern.

       In November 2003, the Company acquired a Patent Portfolio (see Note E)
       and is pursuing licensing opportunities for these patents. However, the
       Company has not entered into any license arrangements as of December 31,
       2003. Until the Company generates positive cash flows from operations, of
       which there can be no assurance, the Company plans to seek additional
       financing through the issuance of debt and/or equity securities.

       The accompanying financial statements have been prepared assuming that
       the Company will continue as a going concern and do not include any
       adjustments that may result from the outcome of this uncertainty.

NOTE B - SIGNIFICANT ACCOUNTING POLICIES

[1]    CASH EQUIVALENTS:

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

                                                                             F-7

NETWORK-1 SECURITY SOLUTIONS, INC.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2003 AND 2002

NOTE B - SIGNIFICANT ACCOUNTING POLICIES  (CONTINUED)

[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. Training revenues are
       recognized as such services are performed. Revenue from advance license
       fees are deferred until they are earned pursuant to the agreements.

[3]    EQUIPMENT AND FIXTURES:

       Equipment and fixtures are stated at cost and are depreciated using the
       straight-line method over their estimated useful lives of five years.

[4]    SOFTWARE DEVELOPMENT COSTS:

       Costs to maintain developed programs and development costs incurred to
       establish the technological feasibility of computer software are expensed
       as incurred. The Company capitalizes costs incurred in producing computer
       software after technological feasibility of the software has been
       established through the date that the software is ready for general
       release to customers. Such costs are amortized based on current and
       estimated future revenue of each product with an annual minimum equal to
       the straight-line amortization over the remaining estimated economic life
       of the product. The Company estimates the economic life of its software
       to be three years.

[5]    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.

[6]    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 cash flows expected to be derived
       from those assets are less than carrying amounts of those assets. During
       the year ended December 31, 2002, the Company recorded an impairment
       charge related to its network security software of approximately
       $401,000, which was included in amortization of software development
       costs. On May 30, 2003, the Company completed the sale of its network
       security software to an unrelated third party for $415,000. At December
       31, 2002, the Company also reduced the carrying value of its fixed assets
       to their net realizable amount and sold them in January 2003 for $22,000,
       that being their carrying value at December 31, 2002 (see Note C).

                                                                             F-8

NOTE B - SIGNIFICANT ACCOUNTING POLICIES  (CONTINUED)

[7]    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.

[8]    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 11,495,493 and
       18,081,581 at December 31, 2003 and 2002, respectively, are
       anti-dilutive, and are not included in the calculation of diluted loss
       per share. Such potential common shares reflect options, warrants,
       convertible preferred stock and convertible notes.

[9]    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.

[10]   FINANCIAL INSTRUMENTS:

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

[11]   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:

       The fair value of options on the date of grant is estimated using the
       Black-Scholes option-pricing model utilizing the following weighted
       average assumptions:

                                                          YEAR ENDED

[12]   ADVERTISING COSTS:

       Advertising costs are expensed as incurred. Advertising expense was $0
       and $93,000 for the years ended December 31, 2003 and 2002, respectively.

[13]   RECENTLY ISSUED ACCOUNTING STANDARDS:

       SFAS No. 150, "Accounting for Certain Financial Instruments with
       Characteristics of Both Liabilities and Equity," which was issued in May
       2003, will require redeemable preferred stock to be classified, in
       certain circumstances, as a liability, upon adoption by a public company
       at the beginning of the first interim period beginning after June 15,
       2003. SFAS No. 150 provides that mandatorily redeemable preferred stock
       should be classified as a liability if it embodies an unconditional
       obligation requiring the issuer to redeem the shares by transferring its
       assets at a specified or determinable date or upon an event certain to
       occur. The Company does not currently have any financial instruments with
       these characteristics. SFAS No. 150 had no effect on the Company's
       results of operations and financial position.

       In November 2002, the FASB issued Interpretation No. 45, "Guarantor's
       Accounting and Disclosures Requirements for Guarantees, Including
       Indirect Guarantees of Indebtedness of Others" ("FIN 45"). FIN 45
       requires that upon issuance of a guarantee, the guarantor must recognize
       a liability for the fair value of the obligation it assumes under that
       guarantee. FIN 45 is effective on a prospective basis to guarantees
       issued or modified after December 15, 2002, but has certain disclosure
       requirements effective for financial statements of interim or annual
       periods ending after December 15, 2002. The Company does not currently
       have any guarantees. The adoption of the disclosure requirements of FIN
       45 had no effect on the Company's financial position or results of
       operations.

       In January 2003, the FASB issued FIN No. 46, "Consolidation of Variable
       Interest Entities" ("FIN 46"). FIN 46 relates to certain entities in
       which equity investors do not have the characteristics of a controlling
       financial interest or do not have sufficient capital at risk for the
       entity to finance its activities without additional subordinated
       financial support from other parties. Under certain circumstances, an
       enterprise may be required to consolidate such an entity if it will
       absorb a majority of the entity's expected losses, receive a majority of
       the entity's residual returns, or both. FIN 46 became effective for
       variable interest entities created after January 31, 2003, and had no
       effect on the Company's financial position as of December 31, 2003, and
       its results of operations for the year then ended.

       Certain prior year amounts have been reclassified to conform to the 2003
       presentation.

NOTE E - 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 controlling stockholders of the Company currently own a
majority of Merlot's voting stock. 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 addtion, the
Company shall 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 licensing of the patents. However, the Company has an option to
terminate these payments for each of the patents, commencing Janaury 1, 2007
through March 31, 2007, and for each Janaury 1 through March 31 period
therafter, by paying the greater of: (i) two times the payment due for the 12
months immediately following the notice 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.

                                                                            F-11

NOTE F - STOCKHOLDERS' EQUITY

[1]    PREFERRED STOCK:

       (a) Series D preferred stock:

           Pursuant to a private placement in December 1999, the Company
           received $1,500,000 from the sale of 491,803 shares of Series D
           convertible preferred stock at $3.05 per share, including 172,129
           shares to related parties. Such stock is convertible into common
           shares at a conversion rate of 1.69431 (as adjusted), has identical
           voting rights as the Company's common stock, and is entitled to
           equivalent dividend rights as those paid on shares of common stock
           obtainable on conversion. The holders of the Series D convertible
           preferred stock are entitled to a liquidation preference of $3.05 per
           share plus any declared but unpaid dividends before any payments are
           made to holders of common stock, and rank equal with Series E
           preferred stock in the event of liquidation, dissolution or winding
           up of the Company. Through December 31, 2001, 384,780 shares of the
           Series D preferred stock were converted to common stock and prior
           outstanding notes were converted into 124,031 shares of the Series D
           preferred stock. In connection therewith, the Company also issued
           five-year warrants to purchase 491,803 shares of common stock at an
           exercise price of $3.05 per share. The exercise price of the warrants
           was reduced to $1.00 because the Company did not achieve a specified
           revenue target. Holders of warrants for 444,857 shares waived such
           exercise price reduction. Of these warrants, 147,149 were exercised
           during 2000.

           Pursuant to anti-dilution features of the Series D convertible
           preferred stock and warrants, in connection with the October 2, 2001
           private offering of Series E preferred stock and warrants (see (b)
           below), the holders of outstanding Series D preferred stock and
           related warrants received the right to purchase 1,145,207 additional
           shares of common stock upon conversion or exercise of Series D
           preferred stock and warrants as a result of the anti-dilution
           provisions of such securities. The warrants expire in December 2004.
           In addition, the exercise price of outstanding warrants was adjusted
           from $3.05 to $1.114.

       (b) Series E preferred stock:

           On October 2, 2001, the Company completed a $6,765,000 private
           offering of Series E preferred stock ("Series E") and warrants (the
           "2001 Financing"). An aggregate of 3,191,037 shares of Series E
           together with warrants to purchase 6,882,074 shares of common stock
           were sold. The warrants were issued at the rate of two warrants, each
           to purchase a share of common stock at $1.27 per share, with every
           share of Series E, plus an additional warrant to purchase 500,000
           shares to an investor,

                                                                            F-12

           License and Distribution Agreement (the "Falconstor Agreement")
           pursuant to which Falconstor has the right to distribute the
           Company's product offerings in its indirect and OEM channels. As part
           of the Falconstor Agreement, Falconstor paid the Company a
           non-refundable advance of $500,000 against future royalty payments
           (the "Advance"). For accounting purposes, $350,000 of the Advance,
           representing the estimated fair value of the Additional Warrant, was
           accounted for as its purchase price, resulting in total proceeds
           attributable to the 2001 Financing of $7,115,000. For accounting
           purposes, an allocation of $4,952,000 and $2,163,000 was made to the
           Series E and warrants, respectively, based on the relative fair
           values of the common stock obtainable upon conversion of the Series E
           and the warrants on the date of the 2001 Financing. The warrants were
           valued using the Black-Scholes option pricing model using the
           following assumptions: volatility of 113.45%, expected life of 1 year
           and 3 years, dividend yield of 0, and risk-free interest rates of
           2.47% and 3.14%, respectively. The difference between the proceeds
           allocated to the Series E and the fair market value of the common
           stock obtainable upon conversion of the Series E represents a
           beneficial conversion feature, which has been imputed as a preferred
           stock dividend in calculating the net loss available to common
           stockholders. On May 30, 2003, as part of the Company's sale of its
           CyberwallPLUS technology and related intellectual property (the
           "Assets") to an unrelated third party (the "Purchaser"), the Company
           assigned its rights under the Falconstor Agreement to the Purchaser.

           Holders of the Series E may convert each such share into two shares
           of common stock at any time, subject to adjustment. During the year
           ended December 31, 2002, holders of 707,529 shares of Series E
           converted their shares into 1,415,058 shares of common stock. The
           Series E is entitled to vote on all matters with the holders of the
           Company's common stock based on the number of shares of common stock
           into which such shares may be converted, except that the holders of
           the Series E have irrevocably waived any increased voting rights that
           may be afforded to the holders of Series E resulting from
           anti-dilution protection. Holders of Series E shall receive dividends
           and other distributions, when, as and if declared by the Board of
           Directors, out of funds legally available therefore equivalent to
           those dividends paid on shares of common stock. The holders of Series
           E will be entitled to a liquidation preference of $2.12 per share
           plus any declared but unpaid dividends before any payments are made
           to holders of common stock, and the Series E ranks equal with the
           Series D preferred stock upon liquidation. The Company also agreed
           with the holders of the Series E that, without the approval of the
           Series E designee, a principal stockholder of the Company (see Note
           J[3]), it will not take certain actions, including (i) issue
           securities except for securities issued under its stock option plan,
           (ii) incur debt in excess of $250,000, (iii) enter into a merger,
           acquisition or sale of substantially all of its assets and (iv) take
           any action to amend its Certificate of Incorporation or by-laws that
           could in any way adversely affect the rights of the holders of the
           Series E. In addition, the investors were granted registration rights
           with respect to the shares of common stock to be received upon
           conversion of the Series E preferred stock and exercise of the
           warrants.

[2]    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.

                                                                            F-13

       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
       optionee owning more than 10% of the voting stock of the Company) ("10%
       stockholder"). The option price for incentive stock options can not 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)  On April 18, 2002, in consideration of additional consulting and
            financial advisory services, the Company issued to CMH Capital
            Management Corp. ("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.
            Corey M. Horowitz, Chairman of the Board of Directors of the
            Company, is the sole owner and officer of CMH. The shares underlying
            the option vest over a three-year period in equal amounts of 250,000
            shares per year beginning April 18, 2003. In addition, the shares
            underlying the option 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 were revalued to $55,000 at December
            31, 2002 and $14,000 at March 31, 2003. The fair value of these
            options remained unchanged at April 18, 2003. On April 18, 2003,
            250,000 of these options, having a fair value of $5,000 as of that
            date, vested. Accordingly, $5,000 was reallocated to additional
            paid-in capital by correspondingly reducing the liability. The
            options to purchase the remaining 500,000 shares continue to be
            treated as contingent options and valued utilizing the Black-Scholes
            option pricing model at each balance sheet date. At December 31,
            2003 the 500,000 unvested options were valued at $54,000. Any
            increase/decrease in the valuation has been reflected as
            addition/reduction of general and administrative expenses at each
            balance sheet date.

       (b)  Includes a five-year option to purchase 294,879 shares of common
            stock at an exercise price of $2.42 per share issued outside the
            1996 Plan which expired in May 2003. The option was issued in May
            1998 in connection with an employment agreement with the Company's
            former President and Chief Executive Officer.

                                                                            F-14

       (c)  On March 11, 2002, the Company entered into a two-year employment
            agreement with Richard J. Kosinski, as Chief Executive Officer and
            President, and issued to Mr. Kosinski ten-year options to purchase
            1,200,000 shares of the Company's common stock at an exercise price
            of $1.65 per share. The vesting schedule for these options was as
            follows: (i) 25% of the shares (300,000 shares) on March 11, 2003
            and (ii) the balance of 75% of the shares over a three-year period
            in equal amounts of 6.25% (75,000 shares) at the end of each
            three-month period beginning March 11, 2003, subject to acceleration
            upon a change of control of the Company. In July 2003, all of these
            options issued were forfeited in connection with the settlement of a
            lawsuit by Mr. Kosinski against the Company.

       (d)  Includes five-year options to purchase 1,600,000 shares of the
            Company's common stock issued to Corey M. Horowitz, Chief Executive
            Officer and Chairman of the Company in connection with an agreement
            in December 2003 (see Note K) 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 shares vested
            immediately, 250,000 shares vest on December 22, 2004 and 200,000
            shares 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.

            the inception of the agreement, 1/3 at 60 days, and 120 days after
            inception. The warrants were valued at $82,000 using the
            Black-Scholes option pricing model using the following weighted
            average assumptions on the issuance dates: risk-free interest rate
            of 5.60, volatility of 113%, dividend yield of 0 and expected life
            of 3 years.

            Executive Officer (see Note J[1]).

       (c)  Issued in connection with the Series D preferred stock and notes.

       (d)  Issued with private offering of Series E preferred stock (see Note
            F[1]).

       (e)  Issued to a software development company for services rendered. The
            Company recognized an $80,000 expense in 2001 related to the
            warrants based on their estimated fair value using the Black-Scholes
            option pricing model utilizing the following weighted average
            assumptions: risk free rate of 4.5%, expected life of 3 years,
            volatility of 113%, and a dividend yield of 0. The software
            development company has claimed they are entitled to additional
            warrants for the services rendered (see Note G[4]).

NOTE J - RELATED PARTY TRANSACTIONS AND RELATIONSHIPS

[1]    In June 2001, upon the resignation of the Company's Chief Executive
       Officer, the Company entered into a six-month consulting agreement with
       CMH, a company owned by the Chairman of the Board of the Company.
       Pursuant to the agreement, the Company paid CMH $17,500 per month and
       issued a warrant to purchase 300,000 shares of the Company's common stock
       at an exercise price of $.70 per share, which was the market price of the
       common stock on the date of issuance. The warrants were valued utilizing
       the Black-Scholes option pricing model, resulting in an estimated fair
       value of $180,000, which was expensed in 2001. In addition, in October
       2001, as consideration for additional consulting and financial services,
       the Company issued warrants to purchase 250,000 shares of common stock at
       an exercise price of $1.48 per share which were expensed. In January
       2002, the agreement was extended to the lesser of six months or three
       months after the date of hire of a new Chief Executive Officer. In July
       2002, the agreement was further extended until December 31, 2002. Until
       December 2003, the Company continued its consulting arrangement with CMH
       on a month-to-month basis. In addition, CMH was reimbursed for $41,000
       and $50,000 of expenses incurred during the years ended December 31, 2003
       and 2002, respectively, including the allocable portion of rent for
       office space in New York City. In December 2003, Mr. Horowitz, the sole
       officer and stockholder of CMH, became Chairman and Chief Executive
       Officer of the Company (see Note K) and the CMH consulting agreement was
       terminated.

[2]    In December 2001, the Company entered into a one-year financial advisory
       agreement with an investment banking firm, which required the Company to
       pay $200,000 over the next ten months. At the time of entering into the
       agreement, the firm's Chairman of the Board owned shares of Series E
       preferred stock and an affiliate was the general partner of a partnership
       that owned common stock and held convertible notes, subsequently
       converted into common stock. During 2002, the Company agreed with the
       investment banking firm that no further services would be needed and that
       payments in the aggregate of $40,000 be considered as full satisfaction
       under the agreement which was accrued at December 31, 2002 and paid in
       January 2003. The Company charged $153,000 to operations during the year
       ended December 31, 2002.

[3]    As noted in F[1], the Company entered into a ten-year License and
       Distribution Agreement with Falconstor, an investor in the 2001
       Financing. This agreement required Falconstor to pay royalties after
       utilizing the Advance as a credit. Deferred revenue at December 31, 2002
       included $130,000 from this agreement, representing the unearned portion
       of the $150,000 allocated from the Advance to the license fee, less
       accumulated royalties earned of $20,000 through December 31, 2002. On May
       30, 2003, as part of the Company's sale of its assets to the purchaser,
       the Company assigned its rights under the Falconstor Agreement to the
       Purchaser of its software (Note L) and recognized as income, the balance
       of the deferred revenue during 2003. One of the Company's principal
       stockholders is also a principal stockholder of Falconstor, and an
       affiliated entity is the Series E designee noted in F[1].


NOTE K - EMPLOYMENT ARRANGEMENTS

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.
The Company will pay a salary of $210,000. In addition, Mr. Horowitz received
options to purchase 1,600,000 shares of common stock (see Note F[2](d). If, at
anytime up to December 31, 2005, the Company completes a financing transaction
and issues common stock or any other securities convertible or exercisable into
common stock, Mr. Horowitz will receive additional options to purchase common
stock, up to a maximum of 600,000 options, so that he will maintain his
ownership percentage of options and warrants as of December 22, 2003.

                                                                            F-19

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 M - SUBSEQUENT EVENTS

[1]    In January 2003, the former Chief Financial Officer and a director (the
       "Former CFO") of the Company commenced a lawsuit against the Company for
       breach of his employment agreement for $190,000. In February 2004, the
       Company agreed to pay $55,000 to the Former CFO in full settlement of all
       claims asserted, which is accrued in the accompanying financial
       statements.

[2]    In January 2004, the Company entered into an agreement with an individual
       to serve as the Company's Chief Financial Officer (the "New CFO"). The
       agreement expires on December 31, 2004 and provides 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 New 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 vest immediately and the
       balance vests on a monthly basis through December 31, 2004.

[3]    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. The Company intends to vigorously defend the
       action and take whatever actions are necessary to protect its
       intellectual property.

[4]    In April 2004, the Company entered into an exchange agreement with the
       holders of the Company's Series E ("Series E") and Series D ("Series D")
       convertible preferred stock to exchange 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).

                                                                            F-20
