ITEM 1.

BUSINESS.

Overview

Our principal business is the acquisition, development, licensing and protection of our intellectual property. We presently own 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 delivery of power over Ethernet cable for the purpose of remotely powering network devices, such as wireless access ports, IP phones and network based cameras, over Ethernet (“PoE”) networks and systems and methods of transmission of audio, video and data in order to achieve high quality of service (QoS). In addition, we continually review opportunities to acquire or license additional intellectual property for the purpose of pursuing licensing opportunities related to our existing intellectual property portfolio or otherwise. Our strategy is to pursue licensing and strategic alliances with companies in industries that manufacture and sell products that make use of the technologies underlying our intellectual property as well as with other users of the technologies who benefit directly from the technologies including corporate, educational and governmental entities.

To date, we have focused our efforts on licensing our remote power patent (U.S. Patent No. 6,218,930) covering the control of power delivery over Ethernet cables (the “Remote Power Patent”). As of March 28, 2011, we had entered eleven (11) license agreements with respect to our Remote Power Patent which, among others, include license agreements with Cisco Systems, Inc. and Cisco-Linksys, Microsemi Corporation, Extreme Networks, Inc., Netgear, Inc., and several other major data networking equipment manufacturers (See Note [C] and Note [J] to our Financial Statements included in Item 8 of this Report.

Our current strategy includes continuing to pursue licensing opportunities for our Remote Power Patent from vendors of Power over Ethernet equipment in order to resolve possible infringement of our Remote Patent by such vendors. We may acquire additional intellectual property assets in the future to develop, commercialize, license or otherwise monetize such intellectual property. We may enter into strategic relationships with third parties to develop, commercialize, license or otherwise monetize their intellectual property. The form of such relationships may vary depending upon the opportunity and may include, among other things, a strategic investment in such third party, the provision of financing to such third party or the formation of a joint venture for the purpose of monetizing such third party’s intellectual property assets.

Our Patents

Our intellectual property currently consists of the following patents:

U.S. Patent No. 6,218,930: Apparatus and method for remotely powering access equipment over a 10/100 switched Ethernet network;

U.S. Patent No. 6,577,631: Communication switching module for the transmission and control of audio, video, and computer data over a single network fabric;

U.S. Patent No. 6,574,242: Method for the transmission and control of audio, video, and computer data over a single network fabric;

U.S. Patent No. 6,570,890: Method for the transmission and control of audio, video, and computer data over a single network fabric using Ethernet packets;

U.S. Patent No. 6,539,011: Method for initializing and allocating bandwidth in a permanent virtual connection for the transmission and control of audio, video, and computer data over a single network fabric; and

U.S. Patent No. 6,215,789: Local area network for the transmission and control of audio, video, and computer data.

In August 2008, we were issued European Patent No. 1086556 titled “Integrated Voice and Data Communications over a Local Area Network” which covers the same technology as covered by our U.S. QoS family of patents. The Patent has issued in France, Germany, Spain, United Kingdom, Ireland and Canada.

Our future success is largely dependent upon our proprietary technologies, our ability to protect our intellectual property rights and consummate license agreements with respect to our intellectual property as well as our ability to acquire additional intellectual property assets or enter into strategic relationships with third parties to license or otherwise monetize their intellectual property. The complexity of patent and common law and the inherent uncertainty of litigation creates risks that our efforts to protect our intellectual property rights, or those of our strategic partners, may not be successful. We cannot be assured that such intellectual property will be upheld, or that third parties will not invalidate such intellectual property rights. In addition, we may not be able to (i) acquire additional intellectual property assets or successfully license such

assets or (ii) successfully enter into strategic relationships with third parties to license or otherwise monetize their intellectual property.

The provisional patent application for our Remote Power Patent 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 patent expires on March 11, 2020.

We were incorporated under the laws of the State of Delaware in July 1990. Our offices are located at 445 Park Avenue, Suite 1018, New York, New York 10022 and our telephone number is (212) 829-5770.

Market Overview – Remote Power Patent

Our licensing efforts for our Patent Portfolio are currently focused on our Remote Power Patent. Our Remote Power Patent (U.S. Patent No. 6,218,930) relates to several technologies which describe a methodology for controlling the delivery of power to certain devices over an Ethernet network.

The Institute of Electrical and Electronic Engineers (IEEE) is a non-profit, technical professional association of more than 370,000 individual members in approximately 160 countries. The Standards Association of the IEEE is responsible for the creation of global industry standards for a broad range of technology industries. In 2000, at the urging of several industry vendors, the IEEE formed a task force to facilitate the adoption of a standardized methodology for the delivery of remote power over Ethernet networks which would insure interoperability among vendors of switches and terminal devices. On June 13, 2003 the IEEE Standards Association approved the 802.3af Power over Ethernet standard (the “Standard”), which covers technologies deployed in delivering power over Ethernet networks. The Standard provides for the Power Sourcing Equipment (PSE) to be deployed in switches or as standalone midspan hubs to provide power to remote devices such as wireless access points, IP phones and network-based cameras. The technology is commonly referred to as Power over Ethernet (“PoE”). We believe that our 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, are able to receive power over existing data cables without the need to modify the existing infrastructure to facilitate the provision of power for such devices through traditional AC outlets. Advantages such as lower installation costs, remote management capabilities, lower maintenance costs, centralized power backup, and flexibility of device location as well as the advent of worldwide power compatibility, create the possibility of PoE becoming widely adopted in networks throughout the world.

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

These and other advantages such as remote management capabilities, lower maintenance costs, and flexibility of device location have led to forecasts that PoE will be widely adopted in networks throughout the world. The benefits of PoE are compelling as evidenced by the introduction of products by such leading vendors such as Cisco Systems, Foundry Networks, Extreme Networks, 3Com, Siemens, Nortel Networks and Avaya, as well as many others.

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

Additional Patents

We also own five (5) additional patents, besides our Remote Power Patent, covering various methodologies that provide for allocating bandwidth and establishing QoS for delay sensitive data, such as voice, on packet data networks. QoS 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. We believe 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.

Potential Patent Acquisitions or Strategic Relationships

We may acquire additional intellectual property assets in the future to develop, commercialize, license or otherwise monetize such intellectual property. We continually review opportunities to acquire or license additional intellectual property from individual inventors and technology companies for the purpose of pursuing licensing opportunities related to our existing intellectual property portfolio or otherwise. In addition, we may enter into strategic relationships with such parties to develop, commercialize, license or otherwise monetize their intellectual property. The form of such relationships may vary depending upon the opportunity and may include, among other things, a strategic investment in such third party, the provision of financing to such third party or the formation of a joint venture for the purpose of monetizing such third party’s intellectual property assets.

Network-1 Strategy

Our strategy is to capitalize on our intellectual property by entering into licensing arrangements with third parties including manufacturers and users that utilize our intellectual property’s proprietary technologies as well as any additional proprietary technologies covered by patents which may be acquired by us in the future. In addition, we may enter into third party strategic relationships with other patent owners to license or otherwise monetize such third party patents. We will also seek to enter into licensing arrangements with users of the proprietary technologies, including corporate,

educational and governmental entities in those cases where the patent rights extend to the users of the technologies contained in manufactured products.

We do not anticipate manufacturing products utilizing our intellectual property or any of the proprietary technologies contained in our intellectual property. Accordingly, we do not anticipate establishing a manufacturing, sales or marketing infrastructure. Consequently, we believe that our capital requirements will be less than the capital requirements for companies with such infrastructure requirements.

In connection with our activities relating to the protection of our intellectual property, or the intellectual property of third parties with whom we have strategic relationships in the future, it may be necessary to assert patent infringement claims against third parties that we believe are infringing our patents or those of our strategic partners. We have in the past successfully asserted litigation to protect our intellectual property, (See Item 3. “Legal Proceedings”).

Licensing – Remote Power Patent

To date we have entered into eleven (11) license agreements with respect to our Remote Power Patent including license agreements with Cisco Systems, Inc. and Cisco Linksys, Microsemi Corporation, Extreme Networks, Inc., Netgear, Inc. and several other major data networking equipment manufacturers (See Note [J] to our Financial Statements included in Item 8 of this Report). We believe that additional potential licensees include, among others, Wireless Local Area Networking (WLAN) equipment manufacturers, Local Area Networking (LAN) equipment manufacturers, Voice Over IP Telephony (VOIP) equipment manufacturers, and network camera manufacturers. In addition, we believe that additional potential licensees include users of the equipment embodying the PoE technology covered by our Remote Power Patent, including corporate, educational and federal, state and local government users, as we believe that they are significant beneficiaries of the technologies covered by our Remote Power Patent.

Licenses with Major Data Networking Equipment Manufacturers (July 2010)

In July 2010, we settled our patent litigation pending in the United States District Court for the Eastern District of Texas, Tyler Division, against Adtran, Inc, Cisco Systems, Inc. and Cisco-Linksys, LLC, (collectively, “Cisco”), Enterasys Networks, Inc., Extreme Networks, Inc., Foundry Networks, Inc., and 3Com Corporation, Inc. As part of the settlement, Adtran, Cisco, Enterasys, Extreme Networks and Foundry Networks each entered into a settlement agreement with us and entered into non-exclusive licenses for our Remote Power Patent (the “Licensed Defendants”). Under the terms of the licenses, the Licensed Defendants paid us aggregate upfront payments of approximately $32 million and also agreed to license our Remote Power Patent for its full term, which expires in March 2020. In addition, Cisco agreed to pay us royalties (beginning in 2011) based on its sales of Power over Ethernet (“PoE”) products up to maximum royalty payments per year of $8 million through 2015 and $9 million per year thereafter for the remaining term of the patent. The royalty payments are subject to certain conditions including the continued validity of our Remote Power Patent, and the actual royalty amounts received may be less than the caps stated above. For more details about the settlement, please see our Current Report on Form 8-K filed with the Securities and Exchange Commission on July 20, 2010.

Netgear License

In May 2009 as part of a settlement of patent infringement litigation in the United States District Court for the Eastern District of Texas, Tyler Division, and under our Special Licensing Program, Netgear entered into a license agreement with us for our Remote Power Patent, effective April 1, 2009. Under the terms of the license, Netgear licenses our Remote Power Patent for its full term which expires in March 2020, and pays quarterly royalties (which began as of April 1, 2009) based on its sales of Power over Ethernet products, including those PoE products which comply with the Institute of Electrical and Electronic Engineers 802.3af and 802.3at Standards. Licensed products include Netgear’s Power over Ethernet enabled switches and wireless access points. The royalty rates included in the Netgear license are 1.7% of the sales price of Power Sourcing Equipment, which includes Ethernet switches, and 2% of the sales price of Powered Devices, which includes wireless access points. The royalty rates are subject to adjustment, under certain circumstances, if we grant a license to other licensees with lower royalty rates and Netgear is able to and agrees to assume all material terms and conditions of such other license. In addition, Netgear paid us $350,000 upon the signing of the license agreement.

Microsemi License

In August 2008, as part of our Special Licensing Program and our agreement with Microsemi Corp-Analog Mixed Signal Group Ltd. (“Microsemi-Analog”), previously PowerDsine Ltd, entered into in June 2008, Microsemi Corporation (“Microsemi”), the parent company of Microsemi-Analog, entered into a license agreement with us with respect to our Remote Power Patent. The license agreement provides that Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales price for certain of its Midspan PoE products for the full term of our Remote Power Patent (March 2020).

D-Link License

In August 2007, we agreed to licensing terms with D-Link Corporation and D-Link Systems (collectively, “D-Link”) as part of a settlement agreement of our patent infringement litigation against D-Link in the United States District Court for the Eastern District of Texas, Tyler Division for infringement of our Remote Power Patent (See Item 3. of this Report - “Legal Proceedings - D-Link Settlement”).

The license terms include the agreement by D-Link to license our Remote Power Patent for its full term which expires in March 2020, and the payment of monthly royalty payments (which began in May, 2007) based upon a running royalty rate of 3.25% of the net sales of D-Link branded Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of our Remote Power Patent based on units of shipments of licensed products. In June 2009, based upon several licenses issued to third parties under our Special Licensing Program, we agreed with D-Link to adjust the royalty rate to 1.7% of the sales price for Power Servicing Equipment (which includes Ethernet switches) and 2.0% of the sales price for Powered Devices (which includes wireless access points). In addition, D-Link paid us an upfront payment of $100,000 upon signing of the license agreement. The products covered by the license include D-Link Power over Ethernet enabled switches, wireless access points, and network security cameras, among others.

Significant Licensees

For the year ended December 31, 2010, Cisco Systems, Inc. and Cisco-Linksys, LLC (collectively, “Cisco”) accounted for 79% of our revenue and Extreme Networks, Inc. accounted for 7.9% of our revenue, respectively. It is anticipated that a few of our licensees will continue to constitute a significant portion of our revenue for the foreseeable future.

Legal Representation

Dovel & Luner, LLP provided legal services to us with respect to our litigation settled in July 2010 against several major data networking equipment manufacturers (See Note [J] to our Financial Statements included as Item 8 of this Report). The terms of our agreement with Dovel & Luner, LLP provided for us to pay legal fees of a maximum aggregate cash payment of $1.5 million plus a contingency fee of up to 24% (based on the settlement being achieved at the trial stage). During the year ended December 31, 2010 we paid Dovel & Luner, LLP (which included legal fees of local counsel) total contingency fees of approximately $7,167,000. In addition, a contingency fee payable to Dovel & Luner, LLP in the amount of $304,000 was accrued at December 31, 2010.

With respect to our litigation against D-Link, which was settled in May 2007 (See Note [J] to our Financial Statements included as Item 8 of this Report), the Company utilized the services of Blank Rome, LLP on a full contingency basis. In accordance with the our contingency fee agreement with Blank Rome LLP, once we recover our expenses related to the litigation (which has not been achieved yet), we are obligated to pay legal fees to Blank Rome LLP equal to 25% of the royalty revenue received by us from our license agreement with D-Link.

Competition

The telecommunications and data networking licensing market is characterized by intense competition and rapidly changing business conditions, customer requirements and technologies. Although we believe that we have enforceable patents, there can be no assurance that our intellectual property will be upheld or that third parties will not invalidate any or all of the patents pertaining to our intellectual property. In addition, our current and potential competitors may develop technologies that may be more effective than our proprietary technologies or that would render our technologies less marketable or obsolete. Therefore, we 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 our Remote Power Patent or other intellectual property. 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 asserts claims relating to our patents, the licensing royalties available to us may be adversely impacted. Moreover, technological advances or entirely different approaches developed by one or more of our competitors or adopted by various standards groups could render our Remote Power Patent obsolete, less marketable or unenforceable.

Furthermore, with respect to our ability to acquire additional intellectual property or enter into strategic relationships with third parties to monetize their intellectual property, we face considerable competition from other companies, many of which have significantly greater financial and other resources than we have. The patent licensing and enforcement industry has grown over the past several years and there has been an increase in the number of companies seeking to acquire intellectual property rights from third parties. Entities including Acacia Research Corporation, Altitude Capital Partners, Intellectual Ventures and RPX Corporation also seek to acquire or partner with third parties to license or enforce intellectual property rights. It is expected that others will enter this market as well. Many of these competitors have significantly more financial and human resources than us.

Description of Property

We currently lease office space in New York City at a cost of $3,740 per month under a lease which expires in May 2011.

Employees and Consultants

As of the date of this Annual Report, we had one full-time employee, no part-time employees and three consultants providing monthly services to us.

ITEM 1A.

RISK FACTORS

We operate in a changing environment that involves numerous known and unknown risks and uncertainties that could materially adversely affect our operations. The following highlights some of the factors that have affected, and in the future could affect, our operations.

We have a history of losses and only achieved profit for the first time in 2010 which may not continue in future years.

We achieved net income of $19,236,000 for the year ended December 31, 2010 primarily due to our receipt of $32,320,000 from settlement of our litigation against seven major data networking equipment manufacturers (See Item 3. “Legal Proceedings – “Settlement of Litigation Against Major Data Networking Equipment Manufacturers”). Prior to the year ended December 31, 2010 we incurred substantial operating losses since inception and as of December 31, 2010 we had an accumulated deficit of $(36,830,000). For the years ended December 31, 2009 and December 31, 2008, we incurred net losses of $(2,578,000) and $(1,618,000), respectively. We had revenue of $33,037,000 and $811,000 from operations for the years ended December 31, 2010 and December 31, 2009, respectively. Our ability to achieve revenue and generate positive cash flow from operations is currently dependent upon receipt of royalty revenue from licensing agreements with respect to our Remote Power Patent and consummating additional license agreements. As of March 23, 2011, we had entered into eleven (11) license agreements with respect to our Remote Power Patent, which among others, includes license agreements with Cisco Systems, Inc. and Cisco-Linksys, Microsemi Corporation, Extreme Networks, Inc. and Netgear, Inc. While we believe based on our current cash position and existing licensing agreements we will have sufficient cash to fund our operations for the foreseeable future, this may not be the case.

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 six patents issued by the U.S. Patent Office that relate to various telecommunications and data networking technologies and include among other things, our Remote Power Patent covering the delivery of power to certain devices over PoE networks and patents covering the transmission of audio, voice and data over computer and telephony networks. We rely upon our patents and trade secret laws, non-disclosure agreements with our employees, consultants and third parties to protect our intellectual property rights. The complexity of patent and common law and the uncertainty of the outcome of litigation 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. If our intellectual property rights are not upheld, such an event would have a material adverse effect on our business, financial condition and results of operations.

Our current revenue is dependent upon the continued validity of our Remote Power Patent.

We currently have 7 license agreements pursuant to which licensees are required to pay us royalties on a quarterly or monthly basis. Such royalty bearing licenses include agreements with Cisco Systems, Inc. and Cisco-Linksys, LLC, Microsemi Corporation, Netgear and D-Link. The obligation of licensees of our Remote Power Patent to continue to make royalty payments to us is contingent upon the continued validity of our Remote Power Patent. In the future it may be necessary for us to commence patent litigation against third parties who we believe require a license to our Remote Power Patent. In addition, we may be subject to claims seeking to invalidate our Remote Power Patent. In the event such patent was determined to be invalid, or unenforceable, or that third parties do not infringe, all licensees of our Remote Power Patent may have no further obligation to make royalty payments to us and thus such a determination would have a material adverse effect on our business, financial condition and results of operations.

Any litigation to protect our intellectual property or any third party claims to invalidate our patents could have a material adverse effect on our business.

In the future, it may be necessary for us to commence patent litigation against third parties whom we believe require a license to our patents. In addition, we may be subject to claims seeking to invalidate our patents, as typically asserted by defendants in patent litigation. If we are unsuccessful in enforcing and validating our patents and/or if third parties making claims against us seeking to invalidate our patents 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. In addition, then existing licensees of our patents may no longer be obligated to pay royalties to us. Successful litigation against us resulting in a determination that our patents are not valid or enforceable, and/or that third parties do not infringe, may have a material adverse effect on us.

Our current licenses for our Remote Power Patent may not result in significant royalties and do not necessarily mean we will achieve additional license agreements.

For the years ended December 31, 2010 and December 31, 2009, we earned aggregate royalty payments of $33,037,000 and $811,000, respectively, with respect to our license agreements for our Remote Power Patent which in 2010 included aggregate up-front payments of approximately $32 million upon settlement of our patent litigation in July 2010 with major data networking equipment manufacturers (See Item 3. “Legal Proceedings” – “Settlement of Litigation Against Major Data Networking Equipment Manufacturers”). We currently have license agreements for our Remote Power Patent with, among others, Cisco Systems, Inc. and Cisco Linksys, LLC, Netgear, Inc., D-Link and Microsemi Corporation pursuant to which such parties are obligated to pay us on-going royalties on a monthly or quarterly basis. Notwithstanding such royalty bearing license agreements we may not achieve significant royalty revenue from such license agreements. In addition, we may not be able to achieve additional material license agreements with third parties relating to our Remote Power Patent. Our failure to achieve significant royalty revenue from our existing license agreements, or if we are

unable to enter into additional license agreements resulting in material royalty revenue, would have a material adverse effect on our business, financial condition and results of operations.

A limited number of our licensees account for a significant portion of our total revenues.

One of our licensees, Cisco Systems, Inc. and Cisco-Linksys, LLC (collectively, “Cisco”), accounted for 79% of our revenue and Extreme Networks, Inc. accounted for 7.9% of our revenue, respectively, for the year ended December 31, 2010. It is anticipated that a few licensees will continue to constitute a significant portion of our revenue for the foreseeable future. To the extent such sales by our significant licensees are adversely affected our revenues will be significantly impacted.

We may not be able to capitalize on our strategy to acquire additional patents or enter into strategic relationships with third parties to license or otherwise monetize their intellectual property.

As a result of our settlement of patent litigation in July 2010 and the success we have achieved to date from licensing our Remote Power Patent, we believe we have the expertise and sufficient capital to effectively compete in the intellectual property acquisition market and to enter strategic relationships with third parties to develop, commercialize, license or otherwise monetize their intellectual property. However, beside the six patents we acquired in November 2003, including our Remote Power Patent, we have not acquired any additional patents and we have not yet entered into any strategic relationships with third parties to license or otherwise monetize their intellectual property. Accordingly, we may not be able to acquire additional intellectual property or, if acquired, we may not achieve material revenue from such intellectual property. Furthermore, we may not be able to enter into strategic relationships with third parties to license or otherwise monetize their intellectual property and, even if we consummate such strategic relationships, we may not achieve material revenue or profit from such relationships.

We face intense competition to acquire intellectual property and enter into strategic relationships.

With respect to our ability to acquire additional intellectual property or enter into strategic relationships with third parties to monetize their intellectual property, we face considerable competition from other companies, many of which have significantly greater financial and other resources than we have. The patent licensing and enforcement industry has grown over the past several years and there has been an increase in the number of companies seeking to acquire intellectual property rights from third parties. Entities including Acacia Research Corporation, Altitude Capital Partners, Intellectual Ventures and RPX Corporation also seek to acquire or partner with third parties to license or enforce intellectual property rights. It is expected that others will enter this market as well. Many of these competitors have significantly more financial and human resources than us.

Our quarterly and annual operating and financial results and our revenue are likely to fluctuate significantly in future periods.

Our quarterly and annual operating and financial results are difficult to predict and may fluctuate significantly from period to period. Our revenue was $33,037,000 for the year ended December 31, 2010 as compared to $811,000 for the year ended December 31, 2009, primarily due to our settlement of our litigation in July 2010. Our revenues and results of operations may fluctuate as a result of a variety of factors that are outside our control including, but not limited to, general economic conditions, our ability and timing in consummating future license agreements for our intellectual property, the timing and extent of royalty payments received by us from our licensees of our Remote Power Patent, the timing and our ability to achieve successful outcomes from future patent litigation, and the timing and our ability to achieve revenue from future strategic relationships.

We may need additional financing to implement our strategy and expand our business.

We may need additional equity or debt financing beyond our existing cash to pursue our strategy including the acquisition of additional intellectual property or to enter into strategic relationships with third parties to license or monetize their intellectual property. Any additional financing that we need may not be available and, if available, may not be available on terms that are acceptable to us. Our failure to obtain financing on a timely basis, or on economically favorable terms, could prevent us from pursuing our intellectual property acquisition strategy or from responding to changing business or economic conditions and could cause us to experience difficulty in withstanding adverse operating results.

Our current business depends upon the continued viability of the PoE market.

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 wide variety of network devices, including IP telephones, wireless LAN access points, web-based network security cameras, data collection terminals and other network devices are able to receive power over existing data cables. To date the market for PoE has continued to expand. The failure of the PoE market to remain viable would have a material adverse effect on licensing revenue for our Remote Power Patent which is currently our sole patent generating licensing revenue.

We do not intend to pay regular future dividends on our common stock and thus stockholders must look to appreciation of our common stock to realize a gain on their investments.

Although we paid a special cash dividend of $0.10 per share to holders of our common stock with a record date of December 13, 2010, we do not have any plans to continue paying dividends in the foreseeable future. Our future dividend policy is within the discretion of our board of directors and will depend upon various factors, including future earnings, if any, operations, capital requirements, our general financial condition,

the preferences of any series of preferred stock, our general business conditions and future contractual restrictions on payment of dividends, if any. Accordingly, stockholders must look solely to appreciation of our common stock to realize a gain on their investment. This appreciation may not occur.

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 PoE 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.

In addition, other companies may develop competing technologies that offer better or less expensive alternatives to PoE and the other technologies covered by our intellectual property. 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 asserts claims relating to our patents, the licensing royalties available to us may be limited. Moreover, technological advances or entirely different approaches developed by one or more of our competitors or adopted by various standards groups could render our Remote Power Patent obsolete, less marketable or unenforceable. Furthermore, with respect to our ability to acquire additional intellectual property or enter into strategic relationships with third parties to monetize their intellectual property, we face considerable competition from companies, many of which have significantly greater financial and other resources than we have.

Dependence upon CEO and Chairman.

Our success is largely dependent upon the personal efforts of Corey M. Horowitz, our Chairman and Chief Executive Officer and Chairman of our Board of Directors. On June 8, 2009, we entered into an employment agreement with Mr. Horowitz pursuant to which he continues to serve as our Chairman and Chief Executive Officer for a three year term. However, the loss of the services of Mr. Horowitz would have a material adverse effect on our business and prospects. We do not maintain key-man life insurance on the life of Mr. Horowitz.

Risks related to low priced stocks.

Our common stock currently trades on the OTC Bulletin Board under the symbol NSSI. Since the trading price of our common stock is below $5.00 per share, our common stock is considered a penny stock. SEC regulations generally define a penny stock to be an equity security that is not listed on a national securities exchange or an automated quotation system sponsored by a registered national securities association, that has a market value of less than $5.00 per share, subject to certain exceptions. SEC regulations require broker-dealers to deliver to a purchaser of our common stock a disclosure schedule explaining the penny stock market and the risks associated with it. Various sales practice requirements are also imposed on broker-dealers who sell penny

stocks to persons other than established customers and accredited investors (generally institutions). Broker-dealers must also provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and monthly account statements disclosing recent price information for the penny stock held in the customer’s account.

The significant number of options and warrants outstanding may adversely affect the market price for our common stock.

As of March 28, 2011, there are outstanding options and warrants to purchase an aggregate of 10,940,915 shares of our common stock at exercise prices ranging from $0.12 to $3.75. To the extent that outstanding options and warrants are exercised, existing stockholder percentage ownership will be diluted and any sales in the public market of the common stock underlying such options may adversely affect prevailing market prices for our common stock.

We may seek to raise additional funds, finance intellectual property acquisitions or develop strategic relationships by issuing capital stock that would dilute your ownership.

Prior to the significant royalty revenue achieved in 2010 as a result of settlement of our patent litigation agreement with major data networking equipment manufacturers, we had largely financed our operations by issuing equity or debt securities, which, if conducted in the future, would materially reduce the percentage ownership of our existing stockholders. Furthermore, any newly issued securities could have rights, preferences and privileges senior to those of our existing stock. Moreover, any issuances by us of equity securities may be at or below the prevailing market price of our stock and in any event may have a dilutive impact on your ownership interest, which could cause the market price of stock to decline. We may also raise additional funds through the incurrence of debt or the issuance or sale of other securities or instruments senior to our common shares. The holders of any debt securities or instruments we may issue could have rights superior to the rights of our common stockholders.

Future sales of shares of our common stock may cause the prevailing market price of our shares to decline and could harm our ability to raise additional capital.

We have previously issued a substantial number of shares of common stock, which are eligible for resale under Rule 144 of Securities Act of 1933, and may become freely tradable. We have also registered a substantial number of shares including shares that are issuable upon the exercise of options and warrants. In addition, if

holders of options and warrants choose to exercise their purchase rights and sell shares of common stock in the public market or if holders of currently restricted common stock or registered common stock sell such shares in the public market, or attempt to publicly sell such shares in a short time period, the prevailing market price for our common stock may decline. Such decline in the price of our common stock may also adversely affect our ability to raise additional capital.

Provisions in our corporate charter and in Delaware law could make it more difficult for a third party to acquire us, could discourage a takeover and adversely affect existing stockholders.

Our certificate of incorporation authorizes the board of directors to issue up to 10,000,000 shares of preferred stock. The preferred stock may be issued in one or more series, the terms of which may be determined at the time of issuance by our Board of Directors, without further action by stockholders, and may include, among other things, voting rights (including the right to vote as a series on particular matters), preferences as to dividends and liquidation, conversion and redemption rights, and sinking fund provisions, any of which could adversely affect holders of our common stock. Although there are currently no shares of preferred stock outstanding, future holders of preferred stock may have rights superior to our common stock and such rights could also be used to restrict our ability to merge with, or sell our assets to third party.

We are also subject to the “anti-takeover” provisions of Section 203 of the Delaware General Corporation Law, which could prevent us from engaging in a “business combination” with a 15% or greater stockholder for a period of three years from the date such person acquired that status unless appropriate board or stockholder approvals are obtained.

These provisions could deter unsolicited takeovers or delay or prevent changes in our control or management, including transactions in which stockholders might otherwise receive a premium for their shares over the then current market price. These provisions may also limit the ability of stockholders to delay, deter or prevent a change of control, or approve transactions that they may deem to be in their best interests.

Our stock price may be volatile.

The market price of our common stock is likely to be highly volatile and could fluctuate widely in price in response to various factors, many of which are beyond our control, including the following:

●

our ability to successfully enforce and/or defend our Remote Power Patent;

●

our ability to enter into favorable license agreements with third parties with respect to our Remote Power Patent;

●

our ability to acquire additional intellectual property;

●

our ability to achieve material revenue and profits;

●

our ability to enter into strategic relationships with third parties to license or otherwise monetize their intellectual property

●

our ability to raise capital when needed;

●

sales of our common stock;

●

our ability to execute our business plan;

●

technology changes;

●

legislative, regulatory and competitive developments; and

●

economic and other external factors.

In addition, the securities markets have from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These market fluctuations may also materially and adversely affect the market price of our common stock.

LEGAL PROCEEDINGS

Settlement of Litigation Against Major Data Networking Equipment Manufacturers

On July 19, 2010, we announced that we had agreed to settle our litigation with Adtran, Inc, Cisco Systems, Inc. and Cisco-Linksys, LLC, (collectively, “Cisco”), Enterasys Networks, Inc., Extreme Networks, Inc., Foundry Networks, Inc., and 3Com Corporation, Inc. pending in the United States District Court for the Eastern District of Texas, Tyler Division. As part of the settlement, Adtran, Cisco, Enterasys, Extreme Networks and Foundry Networks each entered into a settlement agreement with us and entered into non-exclusive licenses for the Remote Power Patent (the “Licensed Defendants”). Under the terms of the licenses, the Licensed Defendants paid us an aggregate upfront payment of approximately $32 million and also agreed to license the Remote Power Patent for its full term, which expires in March 2020. In addition, Cisco agreed to pay royalties (beginning in 2011) based on its sales of Power over Ethernet (“PoE”) products up to maximum royalty payments per year of $8 million through 2015

and $9 million per year thereafter for the remaining term of the patent. The royalty payments are subject to certain conditions including the continued validity of our Remote Power Patent, and the actual royalty amounts received may be less than the caps stated above. The settlement with 3Com provides for a dismissal of the litigation without prejudice. The release covers sales of certain 3Com Power over Ethernet products sold through the date of the settlement. In addition, we and 3Com’s parent, Hewlett Packard Corporation, agreed that the dismissal does not apply to Hewlett-Packard Power over Ethernet products and that any future litigation involving us and Hewlett Packard concerning the Remote Power Patent will be in the United States District Court for the Eastern District of Texas. For more details about the settlement, please see our Current Report on Form 8-K filed with the Securities and Exchange Commission on July 20, 2010.

On May 29, 2009, we announced that we had agreed to a settlement with Netgear, Inc. (“Netgear”), who was also a defendant in the above referenced litigation in United States District Court for the Eastern District of Texas. As part of the settlement and under our Special Licensing Program, Netgear entered into a license agreement with us for our Remote Power Patent and we agreed that all claims and counterclaims involving Netgear in the litigation would be dismissed with prejudice. Under the terms of the license, Netgear licenses the Remote Power Patent from us for its full term (which expires in March 2020), and pays quarterly royalties (which began as of April 1, 2009) based on its sales of Power over Ethernet products, including those Power over Ethernet products which comply with the Institute of Electrical and Electronic Engineers 802.3af and 802.3at Standards. Licensed products include Netgear’s Power over Ethernet enabled switches and wireless access points. The royalty rates included in the license are 1.7% of the sales price of Power Sourcing Equipment, which includes Ethernet switches, and 2% of the sales price of Powered Devices, which includes wireless access points. The royalty rates are subject to adjustment, under certain circumstances, if we grant a license to other licensees with lower royalty rates and Netgear is able to and agrees to assume all material terms and conditions of such other license. In addition, Netgear made a payment of $350,000 to us with respect to the settlement.

D-Link Settlement

In August 2007, we finalized the settlement of our patent infringement litigation against D-Link Corporation and D-Link Systems Incorporated (collectively, “D-Link”) pending in the United States District Court for the Eastern District of Texas. Under the terms of the settlement, D-Link entered into a license agreement for our Remote Power Patent the terms of which included monthly royalty payments of 3.25% (subject to adjustment as noted below) of the net sales of D-Link Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards, for the full term of our Remote Power Patent, which expires in March 2020. In addition, D-Link paid us $100,000 upon signing of the Settlement Agreement. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of our Remote Power Patent based on units of shipments of licensed products. In June 2009, based upon several licenses issued to third parties under our Special Licensing Program, we agreed with D-Link to adjust the royalty rate to 1.7% of the sales price for Power Servicing Equipment (which includes Ethernet switches) and 2.0% of the sales price for Powered Devices (which includes wireless access points).

Microsemi - PowerDsine Settlement

On November 16, 2005, we entered into a Settlement Agreement with PowerDsine, Inc. and PowerDsine Ltd. (collectively, “PowerDsine”) with respect to patent litigation brought by PowerDsine against us in March 2004 in the United States District Court for the Southern District of New York that sought a declaratory judgment that our Remote Power Patent was invalid and not infringed by PowerDsine and/or its customers. Under the terms of the Settlement Agreement, we agreed that, under certain circumstances, we will not initiate litigation against PowerDsine for its sale of Power over Ethernet (PoE) integrated circuits. In addition, we agreed that we will not seek damages for infringement from customers that incorporate PowerDsine integrated circuit products in PoE capable Ethernet switches manufactured on or before April 30, 2006. PowerDsine agreed that it will not initiate, assist or cooperate in any legal action relating to the Remote Power Patent. In June 2008 we entered into a new agreement with Microsemi Corp-Analog Mixed Signal Group Ltd (“Microsemi Analog”), previously PowerDsine Ltd, a subsidiary of Microsemi Corporation (“Microsemi”), a leading manufacturer of high performance analog mixed-signal integrated circuits and high reliability semiconductors, which, among other things, amended the prior Settlement Agreement entered into between the parties in November 2005. As part of our Special Licensing Program and our agreement with Microsemi Analog entered into in June 2008, Microsemi entered into a license agreement, dated August 13, 2008, with us with respect to our Remote Power Patent. The license agreement provides that Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales price for certain of Microsemi’s Midspan PoE products for the full term of our Remote Power Patent (March 2020).

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

Our principal business is the acquisition, development, licensing and protection of our intellectual property. We presently own six patents covering various telecommunications and data networking technologies and include, among others, patents covering the delivery of power over Ethernet for the purpose of remotely powering network devices, such as wireless access ports, IP phones and network based cameras, over Ethernet (“PoE”) networks and systems and methods of transmission of audio, video and data in order to achieve high quality of service (QoS). Our strategy is to pursue licensing and strategic business alliances with companies in the industries that manufacture and sell products that make use of the technologies underlying our intellectual property as well as with other users of the technology who benefit directly from the technology including corporate, educational and governmental entities.

To date, we have focused our efforts on licensing our patent (U.S. Patent No. 6,218,930) covering the control of power delivery over Ethernet cables (the “Remote Power Patent”). As of December 31, 2010, we had entered into 11 license agreements with respect to our Remote Power Patent which, among others, include license agreements with Cisco, Extreme Networks, Inc., Netgear, Inc., Microsemi Corporation and D-Link (See Note [J] to our financial statements included in Item 8 of this Report). Our current strategy includes continuing to pursue licensing opportunities for our Remote Power Patent from vendors of Power over Ethernet equipment in order to resolve possible infringement of the Remote Patent by such vendors. We may acquire additional intellectual property assets in the future to develop, commercialize, license or otherwise monetize such intellectual property. We continually review opportunities to acquire or license additional intellectual property for the purpose of pursuing licensing opportunities related to our existing intellectual property or otherwise. In addition, we may enter into strategic relationships with third parties to develop, commercialize, license or otherwise monetize their intellectual property. The form of such relationships may differ depending upon the opportunity and may include, among other things, a strategic investment in such third party, the provision of financing to such third party or the formation of a joint venture with such third party for the purpose of monetizing its intellectual property assets.

On July 19, 2010, we announced that we had agreed to settle our patent litigation pending in the United States District Court for the Eastern District of Texas, Tyler Division, against Adtran, Inc, Cisco Systems, Inc. and Cisco-Linksys, LLC, (collectively, “Cisco”), Enterasys Networks, Inc., Extreme Networks, Inc., Foundry Networks, Inc., and 3Com Corporation, Inc. As part of the settlement, Adtran, Cisco, Enterasys, Extreme Networks and Foundry Networks each entered into a settlement agreement with us and entered into non-exclusive licenses for the Remote Power Patent (the “Licensed Defendants”). Under the terms of the licenses, the Licensed Defendants paid us aggregate upfront payments of approximately $32 million and also agreed to license the Remote Power Patent for its full term, which expires in March 2020. In addition, Cisco agreed to pay us royalties (beginning in 2011) based on its sales of Power over Ethernet (“PoE”) products up to maximum royalty payments per year of $8 million through 2015 and $9 million per year thereafter for the remaining term of the patent.

The royalty payments are subject to certain conditions including the continued validity of our Remote Power Patent, and the actual royalty amounts received may be less than the caps stated above. For more details about the settlement, please see our Current Report on Form 8-K filed with the Securities and Exchange Commission on July 20, 2010.

On May 29, 2009 we announced that we had reached a settlement with Netgear, Inc. (“Netgear”), who was also a defendant in the above referenced litigation pending in Tyler, Texas. As part of the settlement and under our Special Licensing Program, Netgear entered into a license agreement with us for our Remote Power Patent. Under the terms of the license, Netgear licenses the Remote Power Patent for its full term (which expires in March 2020), and pays quarterly royalties (beginning as of April 1, 2009) based on its sales of Power over Ethernet products, including those Power over Ethernet products which comply with the Institute of Electrical and Electronic Engineers 802.3af and 802.3at Standards. Licensed products include Netgear’s Power over Ethernet enabled switches and wireless access points. The royalty rates included in the license are 1.7% of the sales price of Power Sourcing Equipment, which includes Ethernet switches, and 2% of the sales price of Powered Devices, which includes wireless access points. The royalty rates are subject to adjustment, under certain circumstances, if we grant a license to other licensees with lower royalty rates and Netgear is able to and agrees to assume all material terms and conditions of the other license. In addition, Netgear made a payment to us of $350,000 with respect to the settlement.

In August 2008, as part of our Special Licensing Program and our agreement with Microsemi Corp-Analog Mixed Signal Group Ltd. (“Microsemi-Analog”) entered into in September 2008, Microsemi Corporation (“Microsemi”), the parent company of Microsemi-Analog, entered into a license agreement with us with respect to the Remote Power Patent. The license agreement provides that Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales price for certain of Microsemi’s Midspan PoE products for the full term of the Remote Power Patent (through March 2020).

In August 2007 we finalized the settlement of our patent litigation against D-Link in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of our Remote Power Patent. Under the terms of the settlement, D-Link licenses our Remote Power Patent the terms of which include monthly royalty payments of 3.25% (as adjusted as noted below) of the net sales of D-Link branded Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards, for the full life of our Remote Power Patent, which expires in March 2020. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of our Remote Power Patent based on units of shipments of licensed products. In addition, D-Link paid us $100,000 upon signing the settlement agreement. In September 2009, based upon several licenses issued to third parties under our Special Licensing Program, we agreed with D-Link to adjust the royalty rate to 1.7% of the sales price for Power Servicing Equipment (which includes Ethernet switches) and 2.0% of the sales price for Powered Devices (which includes wireless access points).

RESULTS OF OPERATIONS:

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009

We had revenues of $33,037,000 for the year ended December 31, 2010 (“2010”) as compared to revenues of $811,000 for the year ended December 31, 2009 (“2009”). The significant increase in revenues for 2010 was due to $32,320,000 received from the settlement of our patent litigation in July 2010 (See Note J[1] to our Financial Statements included in Item 8 of this Report).

We had cost of revenue of $9,595,000 and $76,000 for 2010 and 2009, respectively. Included in cost of revenue for 2010 are contingent legal fees to Dovel & Luner, our patent litigation counsel, in the amount of $7,471,000, and other contingent payments arising from the settlement of our patent litigation in July 2010, including aggregate bonus compensation in the amount of $1,651,000 payable to our Chairman and Chief Executive Officer pursuant to his employment agreement and fees of $474,000 paid or accrued to ThinkFire Services USA, Ltd. (See Note E[1] and E[2] to our Financial Statements included in Item 8 of this Report).

The gross profit for 2010 increased $22,707,000 from $735,000 for 2009 to $23,442,000 for 2010. Such increased gross profit was primarily due to the settlement of our patent litigation in July 2010.

General and administrative expenses include overhead expenses, and accounting, legal and other professional services incurred by us. General and administrative expenses increased by $1,358,000 from $2,413,000 for 2009 to $3,771,000 for 2010, due primarily to increased legal fees and other expenses incurred with respect to our patent litigation trial in July 2010.

We had operating income of $19,269,000 for 2010, as compared to an operating loss of ($2,579,000) for 2009 primarily as a result of the settlement of our patent litigation in July 2010.

At December 31, 2010, we had U.S. federal net operating loss carryforwards (NOLs) totaling approximately $28,000,000 expiring between 2020 and 2030. Due to uncertainties surrounding our ability to generate future taxable income to fully realize these assets, a full valuation allowance has been established to offset its estimated unutilized net deferred tax assets at each balance sheet date. Utilization of NOL credit carryforwards can be subject to a substantial annual limitation due to ownership change limitations that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions. Currently, we believe that we have sufficient NOL carryforwards to offset taxable income, if any, for 2010.

No provision for federal income taxes was made for 2010 due to the application of the benefits of our tax loss carry-forwards. A provision of $74,000 was made for state and local income taxes for 2010. No provision for or benefit from federal or state income taxes were recorded for 2009 because we incurred a net operating loss and fully reserved our deferred tax assets as their future realization could not be determined.

As a result of the foregoing, we realized net income of $19,236,000 or $0.79 per share (basic) and $0.67 per share (diluted), respectively, for 2010 as compared to a net loss of ($2,578,000) or $(0.11) per share (basic and diluted) for 2009.

LIQUIDITY AND CAPITAL RESOURCES

We have financed our operations primarily from royalty revenue from licensing our Remote Power Patent and the sale of equity securities. In accordance with our patent litigation settlement achieved in July 2010 with Adtran, Cisco, Enterasys, Extreme Networks and Foundry Networks, we received aggregate upfront payments of approximately $32 million and Cisco agreed to pay us royalties (beginning in 2011) based on its sales of Power over Ethernet (“PoE”) products (See Note D to our Financial Statements included in Item 8 of this Report). As of March 17, 2011 our principal sources of liquidity consisted of cash of approximately $19.5 million and working capital of approximately $19.6 million. We maintain our cash primarily in savings accounts. We do not have any derivative financial instruments. Accordingly, we do not believe that our investments have significant exposure to interest rate risk. As a result of our July 2010 patent litigation settlements, we believe we will have sufficient cash to satisfy our operational and capital requirements for the foreseeable future.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any off-balance sheet arrangements.

CONTRACTUAL OBLIGATIONS

We do not have any long-term debt, capital lease obligations, operating lease obligations, purchase obligations or other long-term liabilities.

Critical Accounting Policies:

Patents:

We own patents that relate to various telecommunications and data networking technologies. We capitalize the costs associated with acquisition, registration and maintenance of the patents and amortize 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.

Revenue Recognition:

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.

CONTROLS AND PROCEDURES.

(a)

Evaluation of Disclosure Controls and Procedures.

Our Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of our disclosure controls and procedures (as defined

in Rule 13a-15(e) of the Securities Exchange Act of 1934) as of the end of the period covered by this Annual Report on Form 10-K. Based upon this review, our officers concluded that, as of the end of the period covered by this Annual Report on Form 10-K, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in applicable rules and forms and is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

(b)

Internal Control Over Financial Reporting

(i)

Management’s Annual Report on Internal Control over Financial Reporting.

Our management is also responsible for establishing and maintaining adequate “internal control over financial reporting” of the company, as defined in Rule 13a-15(f) of the Exchange Act. Internal control over financial reporting is defined as a process

designed by, or under the supervision of, the issuer’s principal executive and principal financial officer and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management, our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2010 using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework. Management believes that this evaluation provides a reasonable basis for its opinion. In connection with this evaluation, our management did not identify any material deficiencies. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our internal controls over financial reporting were effective as of the end of the period covered by this report.

(iii)

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fiscal quarter ended December 31, 2010, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Committees of the Board of Directors

Audit Committee

We do not have a separate audit committee. Our Board of Directors functions as our audit committee in accordance with Section 3(a)58(A) of the Securities Exchange Act of 1934. While we are not listed on AMEX, our Board has adopted its independence rules in making its determination of director independence. Two of our three directors, Robert Pons and Laurent Ohana, are considered independent directors based upon the standard of independence adopted by the Board of Directors as promulgated under Rule 803A of the Company Guide of NYSE AMEX (“AMEX”). Corey M. Horowitz, who does not meet the AMEX requirement for director independence, is also a board member as well as our Chairman and Chief Executive Officer.

As part of our internal control procedures, our two independent directors (Robert Pons and Laurent Ohana) receive quarterly and annual financial statements and consult with our independent accountants prior to filing such financial statements with the SEC. The Company does not have an audit committee financial expert serving on its Board of Directors.

Compensation Committee

Robert Pons is currently the sole member of our Compensation Committee and served in that capacity for 2010 and 2009. The Compensation Committee is responsible for recommending compensation for our executive officers (subject to Board approval), including bonuses and benefits, and administration of our compensation programs, including our Stock Option Plan. Since the Compensation Committee currently consists of a single member, all recommendations of the Compensation Committee concerning compensation for our executive officers are subject to approval by our Board of Directors.

Limitation on Liability and Indemnification Matters

Our 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 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. Our Bylaws provide that we shall indemnify our directors, officers, employees and agents to the fullest extent permitted by law. Our Bylaws also permit us 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. We currently maintain directors’ and officers’ liability insurance. At present, there is no pending litigation or proceeding involving any of our directors, officers, employees or agents where indemnification will be required or permitted. We are not aware of any threatened litigation or preceding that might result in a material claim for such indemnification.

Technical Advisory Board

In November 2004 we established a Technical Advisory Board to assist us with our strategic business plan of maximizing the value of our intellectual property. Upon joining our Technical Advisory Board, each member was issued a five (5) year option to purchase 17,500 shares (fully vested) of our common stock at an exercise price equal to the closing price of the shares on the date of appointment to the Technical Advisory Board.

The members of the Technical Advisory Board include:

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our officers and directors, and persons who own more than ten percent (10%) of a registered class of our equity securities to file reports of ownership and changes in ownership with the SEC. Officers, directors and greater than ten percent (10%) stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. To the best of our knowledge, based solely on review of the copies of such forms furnished to us or amendments thereto, we believe that all Section 16(a) filing requirements applicable to its officers, directors and greater than ten percent (10%) stockholders were complied with during 2010 with the one exception that Corey M. Horowitz, our Chairman and Chief Executive Officer, did not report on a timely basis the extension and reissuance of a warrant to purchase 250,000 shares (as noted below) and approved by our Board on April 16, 2010. Mr. Horowitz subsequently filed a Form 5 with the SEC on February 1, 2010 which reported the 3 year extension (approved by our Board in April 2010) of warrants (expiring in October 2010) to purchase 250,000 shares of our common stock originally issued to CMH Capital Management Corp. (an entity wholly owned by Mr. Horowitz) and reissued to Mr. Horowitz. With respect to any of our former directors, officers, and ten percent (10%) stockholders, we do not have any knowledge of any known failures to comply with the filing requirements of Section 16(a).

Code of Ethics

The Board of Directors has adopted a Code of Ethics that applies to the principal executive officers, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The Code of Ethics is incorporated by reference as Exhibit 14 to this Annual Report on Form 10-K.

(1)	We have concluded that the aggregate amount of perquisites and other personal benefits paid in 2010 and 2009 to either Mr. Horowitz or Mr. Kahn did not exceed $10,000.

(2)

Mr. Horowitz received the following bonus payments for 2010: (i) a discretionary annual bonus of $350,000 for 2010 which was paid in March 2011 and (ii) royalty bonus compensation of $1,651,000 pursuant to his employment agreement.

(3)

The aggregate grant date fair value for 2010 reflects an incremental value of $121,000 due to three-year extensions, approved on April 16, 2010, of options to purchase (i) 750,000 shares of common stock and (ii) 5,000 shares of common stock which were due to expire on April 18, 2010 and September 19, 2010, respectively. In determining the aggregate grant date fair value in accordance with FASB ASC Topic 718 of three-year extensions of three-year options re-issued to Mr. Horowitz to purchase an aggregate of 755,000 shares of common stock, exercisable at $0.68 per share (consisting of an option to purchase 750,000 shares originally issued to CMH Capital Management Corp., an entity owned by Mr. Horowitz, which was re-issued to Mr. Horowitz on April 18, 2010 and an option to purchase 5,000 shares of common stock which was due to expire on September 19, 2010) which extensions were approved on April 16, 2010, we made the following assumptions: expected term of options – 3 years; risk free interest rate for the expected term of the options – 2.71%; expected volatility of the underlying stock – 42.75%; no expected dividends. The aggregate grant date fair value for 2010 also includes $148,000 for the portion that vested in 2010 of options to purchase 750,000 shares of common stock granted to Mr. Horowitz on June 8, 2009. On April 16, 2010 the Board of Directors also approved a three year extension of warrants to purchase 250,000 shares of common stock originally issued to CMH Capital Management Corp., an entity owned by Mr. Horowitz, which were re-issued to Mr. Horowitz on October 8, 2010.

(4)

In determining the aggregate grant date fair value in accordance with FASB ASC Topic 718 of a ten (10) year option issued in June 2009 to Mr. Horowitz to purchase 750,000 shares of common stock, we made the following assumptions: expected term of options – 10 years; risk free interest rate for the expected term of the options – 2.950%; expected volatility of the underlying stock – 62.04%; no expected dividends. The aggregate grant date fair value for 2009 reflects an incremental value of $464,000 due to exercise price adjustments on March 11, 2009 to an adjusted exercise price of $0.68 per share with respect to options and warrants to purchase an aggregate of 4,031,195 shares with exercise prices ranging from $0.70 to $6.00 per share. The aggregate grant date fair value for 2009 also reflects an incremental value of $132,000 due to

five-year extensions, approved on June 8, 2009, of options to purchase an aggregate 417,500 shares which were to expire in 2009. The aggregate grant date fair value for 2009 also reflects an incremental value of $6,000 due to removal in December 2009 of contingent vesting provisions of options to purchase 10,625 shares of common stock at an exercise price of $0.68 per share granted in January, 2001 (so as to make such options immediately exercisable).

(5)	Consists of consulting fees paid to Mr. Kahn for his services as Chief Financial Officer.

(6)

The aggregate grant date fair value for 2010 reflects an incremental value of $11,000 due to a three-year extension of the expiration date of an option, approved on April 16, 2010, to purchase 75,000 shares which was to expire on August 4, 2010, for which we made the following assumptions: expected term of options – 3 years; risk free interest rate for the expected term of the options – 2.71%; expected volatility of the underlying stock – 42.75%; no expected dividends. The aggregate grant date fair value for 2010 also includes $8,000 for the portion that vested in 2010 of options to purchase 100,000 shares of common stock granted to Mr. Kahn on December 18, 2008.

(7)

The aggregate grant date fair value for 2009 reflects an incremental value of $14,000 due to exercise price adjustments on March 11, 2009 to $0.68 per share of the following options: Options to purchase 75,000 shares of common stock at an exercise price of $3.0625 per share granted in August, 2005; and options to purchase 75,000 shares of common stock at an exercise price of $1.50 per share granted in December, 2006.

Narrative Disclosure to Summary Compensation Table

Employment Agreements, Termination of Employment and Change-In-Control Arrangements

On June 8, 2009, we entered into an Employment Agreement (the “Agreement”) with Corey M. Horowitz pursuant to which he continues to serve as our Chairman and Chief Executive Officer for a three year term at an annual base salary of $375,000 (retroactive to April 1, 2009) for the first year and increasing 5% on each of April 1, 2010 and April 1, 2011. Mr. Horowitz also receives a cash bonus in an amount no less than $150,000 on an annual basis for the three year term of the Agreement.

In connection with the Agreement, Mr. Horowitz was issued a ten (10) year option to purchase 750,000 shares of our common stock at an exercise price of $0.83 per share, which vests in equal quarterly amounts of 62,500 shares beginning June 30, 2009 through March 31, 2012, subject to acceleration upon a change of control. Mr. Horowitz shall forfeit the balance of unvested shares if his employment has been terminated “For Cause” (as defined) by us or without Good Reason (as defined) by Mr. Horowitz. In addition to the aforementioned option grant, we extended for an additional five (5) years the expiration dates of all options (an aggregate of 417,500 shares) expiring in the calendar year 2009 owned by Mr. Horowitz. In 2010 we extended for three years options expiring in the calendar year 2010 to purchase an aggregate of 750,000 shares, and warrants expiring in the calendar year 2010 to purchase an aggregate of 250,000 shares of common stock, all originally issued to CMH Capital Management Corp., an entity controlled by Mr. Horowitz.

During 2010 we also extended for three years an option issued to Mr. Horowitz to purchase 5,000 shares of common stock which was due to expire on September 19, 2010.

Under the terms of the Agreement, Mr. Horowitz shall also receive additional bonus compensation in an amount equal to 5% of our royalties or other payments (exclusive of proceeds from the sale of our patents which is covered below) with respect to our remote power patent (U.S. Patent No. 6,218,930), (the “Remote Power Patent”) and 10% (as amended on March 16, 2011) of our royalties and other payments with respect to our other patents besides the Remote Power Patent (the “Additional Patents”) (all before deduction of payments to third parties including, but not limited to, legal fees and expenses and third party license fees) actually received from licensing its patented technologies (including patents owned as of the date of the Agreement and acquired or licensed on an exclusive basis during the period in which Mr. Horowitz continues to serve as an executive officer of our company) (the “Royalty Bonus Compensation”). To the extent that any Royalty Bonus Compensation results from our settlement with a third party and Corey M. Horowitz and CMH Capital Management Corp., an entity owned by Mr. Horowitz are required to release any rights or participate in any settlement arrangement, any Royalty Bonus Compensation arising in such circumstances shall be paid 65% to Corey M. Horowitz and 35% to CMH Capital Management Corp., unless otherwise agreed by us, Mr. Horowitz or CMH. In addition, during the term of his employment, Mr. Horowitz shall also be entitled to additional bonus compensation equal to (i) 5% of the gross proceeds from the sale of our Remote Power Patent and 10% (as amended on March 16, 2011) of the gross proceeds from the sale of the Additional Patents, and (ii) 5% of the gross proceeds from the merger of our company with or into another entity.

In connection with the Agreement, Mr. Horowitz has also agreed not to compete with us as follows: (i) during the term of the agreement and for a period of 12 months thereafter if his employment is terminated “Other Than For Cause” (as defined) provided he is paid his 12 month base salary severance amount and (ii) for a period of two years from the termination date, if terminated “For Cause” by us or “Without Good Reason” by Mr. Horowitz.

On February 3, 2011, we entered into a new agreement with David C. Kahn pursuant to which he continues to serve as our Chief Financial Officer through December 31, 2012. In consideration for his services, Mr. Kahn is compensated at the rate of $9,000 per month for the year ended December 31, 2011 and is compensated at the rate of $9,450 per month for the year ended December 31, 2012. In connection with the agreement, Mr. Kahn was also issued a five (5) year option (the “Option”) to purchase 100,000 shares of our common stock at an exercise price of $1.59 per share. The option vested 50,000 shares on the date of grant and the balance of the shares (50,000) will vest on the one year anniversary date (February 3, 2012) from the date of grant. Upon a “Change in Control” (as defined) all of the unvested shares underlying the Option shall become 100% vested and immediately exercisable. The agreement

further provides that we may terminate the agreement at any time for any reason. In the event Mr. Kahn’s services are terminated without “Good Cause” (as defined), he will be entitled to accelerated vesting of all unvested shares underlying the Option and the lesser of (i) six months base monthly compensation or (ii) the remaining balance of the monthly compensation payable through December 31, 2012.

Profit Sharing 401(k) Plan

We offer all employees who have completed a year of service (as defined) participation in a 401(k) retirement savings plan. 401(k) plans provide a tax-advantaged method of saving for retirement. We accrued matching contributions of $32,500 under the 401(k) plan for the year ended December 31, 2010.

Director Compensation

We compensate each director who is not an employee of our company by granting to each such outside director (upon joining the Board) stock options to purchase 50,000 shares of our common stock, at an exercise price equal to the closing price of our common stock on the date of grant, with the options vesting over a one year period in equal quarterly amounts. In addition, beginning with the three month period ended September 30, 2010, we pay our outside directors cash director fees of $10,000 per quarter (for the first two quarters of 2010 cash director fees were $5,000 per quarter).

Notes to Financial Statements

December 31, 2010 and 2009

Note A - The Company

Network-1 Security Solutions, Inc. (the “Company”) is engaged in the acquisition, development, licensing and protection of its intellectual property. The Company presently own six patents that relate to various telecommunications and data networking technologies and include, among other things, patents covering the delivery of power over Ethernet cable for the purpose of remotely powering network devices, such as wireless access ports, IP phones and network based cameras, over Ethernet (“PoE”) networks and systems and methods of transmission of audio, video and data in order to achieve high quality of service (QoS). The Company’s strategy is to pursue licensing and strategic alliances with companies in industries that manufacture and sell products that make use of the technologies underlying its intellectual property as well as with other users of the technologies who benefit directly from the technologies including corporate, educational and governmental entities. To date, the Company has focused its efforts on licensing its remote power patent (U.S. Patent No. 6,218,930) covering the control of power delivery over Ethernet cables (the “Remote Power Patent”). The Company has entered eleven (11) license agreements with respect to our Remote Power Patent. The Company’s current strategy includes continuing to pursue licensing opportunities for its Remote Power Patent from vendors of Power over Ethernet equipment in order to resolve possible infringement of its Remote Patent by such vendors. In addition, the Company may acquire additional intellectual property assets in the future to develop, commercialize, license or otherwise monetize such intellectual property. The Company continually reviews opportunities to acquire or license additional intellectual property for the purpose of pursuing licensing opportunities related to its existing intellectual property portfolio or otherwise. In addition, the Company may enter into strategic relationships with third parties to develop, commercialize, license or otherwise monetize their intellectual property.

Note B –Summary of Significant Accounting Policies

[1]	Cash equivalents:

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

[2]	Revenue recognition:

The Company recognizes revenue received from the licensing of its intellectual property in accordance with Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB No. 104”) and related authoritative pronouncements. Under this guidance, revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been performed pursuant to the terms of the license agreement, (iii) amounts are fixed or determinable and (iv) collectability of amounts is reasonably assured.

[3]

Patents:

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

[4]	Impairment of long-lived assets:

Intangible assets with finite lives are tested for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable. Accordingly, the Company records impairment losses on long-lived assets used in operations or expected to be disposed of when indicators of impairment exist and the undiscounted cash flows expected to be derived from those assets are less than carrying amounts of those assets. During the years ended December 31, 2010 and 2009, there was no impairment to its patents.

December 31, 2010 and 2009

Note B – Summary of Significant Accounting Policies (continued)

[5]	Income taxes:

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

[6]	Earnings (Loss) Per Share

Basic Earnings (loss) per share is calculated by dividing the net income (loss) by the weighted average number of outstanding common shares during the period. Diluted per share data included the dilutive effects of options, warrants and convertible securities. Potential shares of 10,569,240 and 12,579,312 at December 31, 2010 and 2009, respectively, consisted of options and warrants. Computations of basic and diluted weighted average common shares outstanding are as follows:

	2010		2009

Weighted-average common shares outstanding - basic		24,422,567		24,135,557

Dilutive effect of options and warrants		4,197,415		—

Weighted-average common shares outstanding - diluted		28,619,982		24,135,557

Options and Warrants excluded from the computation of diluted income (loss) per share because the effect of inclusion would have been anti-dilutive		6,371,825		12,579,312

[7]	Use of estimates:

[8]	Financial instruments:

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

[9]	Stock-based compensation:

The Company accounts for its stock-based compensation at fair value estimated on the grant date using the Black-Scholes option pricing model. See Note D[1] for further discussion of the Company’s stock-based compensation.

[10]	Subsequent event evaluation:

The Company has evaluated subsequent events from the balance sheet date through the issuance date of the financial statements and has determined that there are no such events that would have a material impact on the financial statements (see Note K).

[11]	Recently issued accounting standards:

In January 2010, a pronouncement was issued to improve the disclosures about fair value measurements as required under ASC Topic 820 (Accounting Standards Updated (“ASU”) No. 2010-06). This amendment requires an entity to: (i) disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers, (ii) disclose separately the reasons for any transfers in and out of Level 3, and (iii) present separate information for Level 3 activity pertaining to gross purchases, sales, issuances, and settlements. This amendment is effective for interim and annual reporting periods beginning after December 15, 2009, with one new disclosure effective after December 15, 2010. We adopted this pronouncement as of May 1, 2010. As this pronouncement relates to disclosure only, the adoption did not impact our financial condition, results of operations or cash flows.

In December 2010, a pronouncement was issued that modified the process used to test goodwill for impairment. The pronouncement impacted reporting units with zero or negative carrying amounts and required an additional test to be performed to determine whether goodwill has been impaired and to calculate the amount of that impairment. This amendment is effective for fiscal years beginning after December 15, 2010. We will adopt this pronouncement as of January 30, 2011. We are currently evaluating the potential impact, if any, the adoption of this pronouncement will have on our consolidated financial condition, results of operations or cash flows.

In April 2010, the FASB issued Accounting Standards Update 2010-13, Compensation—Stock Compensation (Topic 718): Effect of Denominating the Exercise Price of a Share-Based Payment Award in the Currency of the Market in Which the Underlying Equity Security Trades. ASU 2010-13 updates ASC 718 to codify the consensus reached in EITF Issue No. 09-J, Effect of Denominating the Exercise Price of a Share-Based Payment Award in the Currency of the Market in Which the Underlying Equity Security Trades. The ASU clarifies that share-based payment awards with an exercise price denominated in the currency of a market in which a substantial portion of the underlying equity security trades should not be considered to meet the criteria requiring classification as a liability. The updated guidance is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2010. Early adoption is permitted. The provisions of ASU 2010-13 are not expected to have an impact on the Company’s financial statements.

Note C- Patents

In November 2003, the Company acquired a portfolio of telecommunications and data networking patents (six patents) from Merlot Communications, Inc. (the “Seller”) in which certain then principal stockholders of the Company owned a majority of the Seller’s voting stock at the time of the transaction. The purchase price for the patent portfolio was $100,000, paid in cash. As additional consideration for the purchase, the Company granted the Seller a nonexclusive, royalty free, perpetual license for the term of each patent to use the patents for the development, manufacture or sale of its own branded products to end users. The cash price has been capitalized and is being amortized over the remaining useful life of each patent. The Company had agreed to pay the Seller 20% of the net income, as defined, after the first $4,000,000 of net income realized by the Company on a per patent basis from the sale or licensing of the patents. On January 18, 2005, the Company and Seller amended the Patent Purchase Agreement “Amendment”) pursuant to which the Company paid additional purchase price of $500,000 to Seller in consideration for the restructuring of future contingent payments to Seller from the licensing or sale of the Patents. Such $500,000 has been recorded as an expense in the prior year.

Note C- Patents (continued)

The Amendment provides for future contingent payments by the Company to Seller of $1.0 million upon achievement of $25 million of Net Royalties (as defined), an additional $1.0 million upon achievement of $50 million of Net Royalties and an additional $500,000 upon achievement of $62.5 million of Net Royalties from licensing or sale of the patents acquired from the Seller. Amortization expense amounted to $9,000 for both years ended December 31, 2010 and 2009.

Note D - Stockholders’ Equity

[1]	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, provided for the granting of both incentive and non-qualified options to purchase common stock of the Company. A total of 4,000,000 were eligible to be issued under the 1996 Plan. As of March 2006, in accordance with the terms of the plan, no further options were eligible to be issued under the Plan.

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

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
	December 31,
	2010	2009

Risk-free interest rates	2.71%	2.54% - 2.95%
Expected option life in years	5 years	5-10 years
Expected stock price volatility	42.25%	62.04%
Expected dividend yield	0.00%	0.00%

The weighted average fair value on the option grant date during the years ended December 31, 2010 and 2009 were $0.37 and $0.59 per option, respectively.

The following table summarizes stock option activity for the years ended December 31:

	2010		2009
		Weighted		Weighted
		Average		Average
	Options	Exercise	Options	Exercise
	Outstanding	Price	Outstanding	Price

Note E - Commitments and Contingencies

[1]	Services agreement:

On November 30, 2004, the Company entered into a master services agreement (the “Agreement”) with ThinkFire Services USA, Ltd. (“ThinkFire”) pursuant to which ThinkFire has been granted the exclusive worldwide rights (except for direct efforts by the Company and related companies) to negotiate license agreements for the Remote Power Patent with respect to certain potential licensees agreed to between the parties. Either the Company or ThinkFire can terminate the Agreement upon 60 days’ notice for any reason or upon 30 days’ notice in the event of a material breach. The Company agreed to pay ThinkFire a fee not to exceed 20% of the royalty payments received from license agreements consummated by ThinkFire on its behalf after the Company recovers its expenses. As of December 31, 2010 the Company had paid ThinkFire $340,000 and accrued an additional $133,673 in fees.

[2]	Legal fees:

Dovel & Luner, LLP provided legal services to the Company with respect to the Company’s patent litigation settled in July 2010 against several major data networking equipment manufacturers. (See Note J). The terms of the Company’s agreement with Dovel & Luner, LLP provided for legal fees of a maximum aggregate cash payment of $1.5 million plus a contingency fee of up to 24% (based on the settlement being achieved at the trial stage) including legal fees of local counsel in Texas. During the years ended December 31, 2010 and 2009, total contingency fee paid to Dovel & Luner, LLP approximated $7,167,000 and $36,000, respectively. In addition, contingency fee in the amount of $304,000 was accrued at December 31, 2010.

With respect to the Company’s litigation against D-Link, which was settled in May 2007 (See Note J), the Company utilized the services of Blank Rome, LLP, on a full contingency basis and also the services of Potter Mitton, P.C. (Tyler, Texas) on an hourly basis to serve as local counsel. In accordance with the Company’s contingency fee agreement with Blank Rome LLP, once the Company recovers its expenses related to the litigation (which has not been achieved yet), the Company is obligated to pay legal fees to Blank Rome LLP equal to 25% of the royalty revenue received by the Company from its license agreement with D-Link.

Note F – Income Taxes

At December 31, 2010, the Company had U.S. federal net operating loss carryforwards (NOLs) totaling approximately $28,000,000 expiring between 2020 and 2030. Due to uncertainties surrounding the Company’s ability to generate future taxable income to fully realize these assets, a full valuation allowance has been established to offset its estimated unutilized net deferred tax assets at each balance sheet date. Utilization of NOL credit carryforwards can be subject to a substantial annual limitation due to ownership change limitations that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions. Currently, the Company believes that it has sufficient NOL carryforwards to offset taxable income, if any, for 2010.

The principal components of the net deferred tax assets are as follows:

	Year Ended
	December 31,
	2010			2009

Deferred tax assets:
Net operating loss carryforwards	$	10,475,000		$	17,503,000
Options and warrants not yet deducted, for tax purposes		1,300,000			970,000

		11,775,000			18,473,000
Valuation allowance		(11,775,000	)		(18,473,000	)

Net deferred tax assets	$	0		$	0

The Company has recorded a valuation allowance for the full amount of its deferred tax assets as the likelihood of the future realization cannot be presently determined. The valuation allowance decreased by $6,698,000 in 2010 and increased by $353,000 in 2009.

The reconciliation between the taxes as shown and the amount that would be computed by applying the statutory federal income tax rate to the loss before income taxes is as follows:

	Year Ended
	December 31,
	2010	2009

Income tax - statutory rate	34.0%	(34.0)%
State and local, net	3.5%	(3.5)%
Valuation allowance on deferred tax assets	(37.5)%	37.5%
(Utilization of NOL)

Note J – Litigation

[1]

In July 2010, the Company announced that it agreed to settle its patent litigation pending in the United States District Court for the Eastern District of Texas, Tyler Division, against Adtran, Inc., Cisco Systems, Inc. and Cisco-Linksys, LLC, (collectively, “Cisco”), Enterasys Networks, Inc., Extreme Networks, Inc., Foundry Networks, Inc., and 3Com Corporation, Inc., pending in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of the Company’s Remote Power Patent, U.S. Patent No. 6,218,930 (“Remote Power Patent”). As part of the settlement, Adtran, Cisco, Enterasys, Extreme Networks and Foundry Networks each entered into a settlement agreement with the Company and agreed to enter into non-exclusive licenses for the Remote Power Patent (the “Licensed Defendants”). Under the terms of the licenses, the licensed Defendants paid to the Company an aggregate upfront payment of approximately $32 million and also agreed to license the Remote Power Patent for its full term, which expired in March 2020. In addition, Cisco agreed to pay royalties (beginning in 2011) based on its sales of Power over Ethernet (“PoE”) products up to maximum royalty payments per year of $8 million through 2015 and $9 million per year thereafter for the remaining term of the patent. The royalty payments are subject to certain conditions including the continued validity of the Company’s Remote Power Patent, and the actual royalty amounts received may be less than the caps stated above. The settlement with 3Com Power over Ethernet products sold through the date of the settlement. In addition, the Company and 3Com’s parent, Hewlett Packard Corporation, agreed that the dismissal does not apply to Hewlett-Packard Power over Ethernet products and that any future litigation involving the Company and Hewlett Packard concerning the Remote Power Patent will be in the United States District Court for the Eastern District of Texas.

Note J – Litigation (continued)

In May 2009 the Company achieved a settlement with Netgear, Inc. (“Netgear”), also a defendant in the above referenced litigation in Tyler, Texas. As part of the settlement and under its Special Licensing Program, Netgear entered into a license agreement with the Company for the Remote Power Patent and the Company agreed that all claims and counterclaims involving Netgear in the litigation would be dismissed with prejudice. Under the terms of the license, Netgear licenses the Remote Power Patent from the Company for its full term (which expires in March 2020), and pays quarterly royalties (beginning as of April 1, 2009) based on its sales of Power over Ethernet products, including those Power over Ethernet products which comply with the Institute of Electrical and Electronic Engineers 802.3af and 802.3at Standards. Licensed products include Netgear’s Power over Ethernet enabled switches and wireless access points. The royalty rates included in the license are 1.7% of the sales price of Power Sourcing

Equipment, which includes Ethernet switches, and 2% of the sales price of Powered Devices, which includes wireless access points. The royalty rates are subject to adjustment, under certain circumstances, if the Company grants a license to other licensees with lower royalty rates and Netgear is able to and agrees to assume all material terms and conditions of such other license. In addition, Netgear made a payment of $350,000 to the Company with respect to the settlement.

[2]	D-Link Settlement

In August 2007, the Company finalized the settlement of its patent infringement litigation against D-Link. Under the terms of the settlement, D-Link entered into a license agreement for the Company’s Remote Power Patent the terms of which include monthly royalty payments of 3.25% (subject to adjustment as noted below) of the net sales of D-Link Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards, for the full term of the Company’s Remote Power Patent, which expires in March 2020. In addition, D-Link paid the Company $100,000 upon signing of the Settlement Agreement. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of the Company’s Remote Power Patent based on units of shipments of licensed products. In June 2010, based upon several licenses issued to third parties under the Company’s Special Licensing Program, the Company agreed with D-Link to adjust the royalty rate to 1.7% of the sales price for Power Servicing Equipment (which includes Ethernet switches) and 2.0% of the sales price for Powered Devices (which includes wireless access points).

[3]	Microsemi - PowerDsine Settlement

On November 16, 2005, the Company entered into a Settlement Agreement with PowerDsine, Inc. and PowerDsine Ltd. (collectively, “PowerDsine”) which dismissed, with prejudice, patent litigation brought by PowerDsine against the Company in March 2004 in the United States District Court for the Southern District of New York that sought a declaratory judgment that the Company’s Remote Power Patent was invalid and not infringed by PowerDsine and/or its customers. Under the terms of the Settlement Agreement, the Company agreed that, under certain circumstances, it would not initiate litigation against PowerDsine for its sale of Power over Ethernet (PoE) integrated circuits. In addition, the Company agreed that it would not seek damages for infringement from customers that incorporate PowerDsine integrated circuit products in PoE capable Ethernet switches manufactured on or before April 30, 2006. PowerDsine agreed that it will not initiate, assist or cooperate in any legal action relating to the Remote Power Patent. In June 2008 the Company entered into a new agreement with Microsemi Corp-Analog Mixed Signal Group Ltd (“Microsemi Analog”), previously PowerDsine Ltd, a subsidiary of Microsemi Corporation (“Microsemi”), a leading manufacturer of high performance analog mixed-signal integrated circuits and high reliability semiconductors, which, among other things, amended the prior Settlement Agreement entered into between the parties in November 2005. As part of the Company’s Special Licensing Program and its agreement with Microsemi Analog entered into in June 2009, Microsemi entered into a license agreement, dated August 13, 2008, with the Company with respect to its Remote Power Patent. The license agreement provides that Microsemi is obligated to pay the Company quarterly royalty payments of 2% of the sales price for certain of Microsemi’s Midspan PoE products for the full term of our Remote Power Patent (March 2020).
