Our CYBERWALLPLUS(TM) family of security software products can reside anywherecombines the benefits of firewall and intrusion detection technology with central management features to provide an enterprise-class layer of security protection directly on the enterprise networkservers, desktops, wireless and mobile computers. CYBERWALLPLUS's distributed intrusion prevention technology provides multiple layersa layer of defense immediately between host machines and the network, complementing network-based security solutions. This bi-directional layer of defense contains mechanisms to protect datathe network from both external attackthe host machine, as well as access abuse by such "trusted insiders" as employees, subcontractorsprotecting the host machine from the network, regardless of whether the source of attack is inside or consultants. Our CYBERWALLPLUS(TM) suiteoutside the organization. CYBERWALLPLUS continues to protect mobile computers even when they connect to networks outside the organization's control. CYBERWALLPLUS represents the latest generation of our security products was first introduced in March 1999 and evolved from our prior FIREWALL/PLUS suitewhich integrates a powerful range of security software products. We also offer our customers a full range of consulting servicestechniques to actively detect and block intrusions. This technology provides the fine-grained access control, bi-directional protection and stateful packet inspection typically found in networkhigh-end perimeter firewalls, combined with powerful intrusion detection and prevention capabilities. CYBERWALLPLUS's policy management enables detailed security policies to be formulated, distributed, and network design and support in order to build, maintain and enhance customer relationships and increase the demand for our software products. The CYBERWALLPLUS(TM) family ofmonitored, maximizing IT security solutions is designed to protect against Internet and Intranet based security threats and to address security needs that arise from within internal networks that often utilize other network transport protocols besides TCP/IP (the Internet network transport protocol). We have positioned our CYBERWALLPLUS(TM) products as an enabling technology designed to capitalize on the significant network security opportunity within the explosive E-Business marketplace. Our CYBERWALLPLUS(TM) family of network security products operates on the Microsoft Windows NT operating system platform. CYBERWALLPLUS'(TM) filter engine software technology, with its unique ability to handle and filter all commonly used network transport protocols, provides organizations with a highly secure and flexible security solution. Additionally, unlike most firewall solutions which focus on an enterprise's connection to the Internet, the CYBERWALLPLUS(TM) solution can be deployed throughout the enterprise. It can be deployed at the perimeter to control access to and from the Internet, between internal networks as well as on application servers and desktop PCs.resources. Every day, more and more companies are turning to E-Business and extranetsthe Internet as a way to obtain a competitive edge and broaden their markets. The E-BusinessInternet revolution is helping companies reduce costs, increase responsiveness and provide empowerment through immediate knowledge. However, by tying together previous separatedisparate company network's, "islands of isolation,"networks, and by inviting customers, partners and suppliers onto their networks, companies have found that what were once closed and secure enterprise networks are now becoming open networks.networks accessible to authorized and, in many instances, unauthorized users. Within these new open networks, the traditional perimeters and network boundaries have disappeared. We do not believe traditional perimeter security devices such as firewalls can effectively secure all of a network's resources which have embraced E-Business. Our CYBERWALLPLUS(TM)resources. The CYBERWALLPLUS family of products is designed to solveaddress this problem by securing the host computer which has the dual result of protecting its data where it resides - between the internalas well as protecting other network segments and inside the server itself - finally allowing - -------------------------------------------------------------------------------- 1 - -------------------------------------------------------------------------------- corporationsresources from attacks originating from that computer. We believe this will allow organizations to leverage the promise of electronic business, while ensuring the safety of their strategic data assets. We are currently pursuing an aggressive growth strategy focusing our efforts on marketing our CyberwallPLUS(TM) family of network security products.- -------------------------------------------------------------------------------- 1 - -------------------------------------------------------------------------------- Key elements of our strategy are to: o Provide comprehensiveSecure an organization's most important servers. This includes database servers for confidential or sensitive data and application servers critical to business operations by replacing or complimenting perimeter firewalls with our server based firewalls and intrusion prevention software; o Secure an organization's most vulnerable client computers. This includes workstations as well as mobile laptop computers which are particularly vulnerable to threats when outside the corporate network and represent an ever increasing percentage of the user community; o Emphasize internal network security solutions by developing, marketingas an important element of an effective multi-layer defense strategy; and supporting a family of network security products designed to address a broad range of security issues confronting computer networks and computing, including protecting data throughout an enterprise, such as between the internal network segments and inside servers. o Emphasize the distinguishing characteristics of the CYBERWALLPLUS(TM) technology, which can reside anywhere on the enterprise network, and inspect, detect and protect access to sensitive corporate data for a multitude of network protocols. Unlike traditional firewalls, which protect organizations from external attacks, cyberwalls protect networks from abuses by those with "inside access" as well. o Implement a marketingsales plan which includesthat utilizes a multi-channel distribution strategy, which emphasizesincluding selling direct to end user customers and establishing and maintaining indirect third-party distributorresale relationships with OEMs, systems integrators VARs, OEMs and resellersVARs in the United States and internationally. o Increase sales of CYBERWALLPLUS(TM) by leveraging relationships with consulting clients. Since our inception, we have incurred significant losses. Our future success is largely dependent upon our CYBERWALLPLUS(TM) family of software products achieving broad market acceptance. We may not be able to successfully implement our marketing strategy, achieve significant revenues and market acceptance of our CYBERWALLPLUS(TM) family of software products, or achieve profitable operations.

RECENT DEVELOPMENTS OCTOBER 2001 PRIVATE FINANCING On December 22, 1999,October 2, 2001, we signedcompleted a Securities Purchase Agreement for the private saleoffering of $3,000,000$6,765,000 of preferred stock warrants and noteswarrants to a group of 39 investors. In - -------------------------------------------------------------------------------- 2 - -------------------------------------------------------------------------------- this transactionsuch financing we issued 491,8033,191,037 shares of our Series DE Preferred Stock at $3.05$2.12 per share and warrants to purchase 491,8036,882,074 shares of our common stock at an exercise price of $3.00 per share, subject to certain adjustments. We also issued convertible promissory notes in the principal amount of $1.5 million at an interest rate of 8% per year.

EACH PROSPECTIVE INVESTOR SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS BEFORE MAKING AN INVESTMENT DECISION. WE HAVE A HISTORY OF LOSSES AND IF WE DO NOT ACHIEVE PROFITABILITY, WE MAY NOT BE ABLE TO CONTINUE OUR BUSINESS IN THE FUTURE. We have incurred substantial operating losses since our inception, which has resulted in an accumulated deficit of approximately $18,347,000$30,538,000 as of September 30, 1999.2001. For the years ended December 31, 2000 and 1999, and the nine (9) months ended September 30, 1999 and the fiscal years ended December 31, 1998 and 1997,2001, we incurred net losses of $5,100,000, $5,777,000$4,789,000, $6,946,000 and $2,390,000,$4,056,000, respectively. Since September 30, 2001, we have continued to incur substantial operating losses. We have financed our operations primarily through the sales of equity and debt securities.securities as well as the sale of our professional services business in February 2000. Our expense levels are high and our revenues are difficult to predict. We anticipate incurring additional losses until we increase our client base and revenues. We may never achieve or sustain significant revenues or profitability. If we are unable to achieve increased revenues, we will continue to have losses and may not be able to continue our operations. WE COULD BE REQUIRED TO CUT BACK OR STOP OPERATIONS IF WE ARE UNABLE TO RAISE OR OBTAIN NEEDED FUNDING. Our ability to continue operations will dependWe anticipate, based on our positive cash flow, if any, from future operations orcurrently proposed plans and assumptions (including the timetable of, costs and expenses associated with, and success of, our ability to raise additional funds through equity or debt financing. In December 1999, we consummated a private financing of $3.0 million of equity and debt in order to obtain the working capital necessary to continue to finance our operations and execute our business plan. See "Recent Developments." Although we anticipatemarketing efforts), that future revenues and our current cash balanceposition and projected revenues from operations, will more likely than not be sufficient to fundsatisfy our operations and capital requirements until approximately May 2000, we cannot give you anyfor up to twelve (12) months. There can be no assurance, however, that wesuch funds will not needbe expended prior thereto due to unanticipated changes in economic conditions or other unforeseen circumstances. In the event our plans change, or our assumptions change or prove to be inaccurate (due to unanticipated expenses, difficulties, delays or otherwise), or the projected revenues otherwise prove to be insufficient to fund our working capital requirements, we could be required to seek additional funds before such time.financing sooner than currently anticipated. We have no current arrangements forwith respect to any additional financing. Consequently, there can be no assurance that any additional financing and we may notwill be ableavailable to us when needed, on commercially reasonable terms or at all. Any inability to obtain additional financing when needed would have a material adverse effect on commercially reasonable terms, if at all. We could be requiredour operations, requiring us to cut back or stop operations if we are unable to raise or obtain funds when needed.curtail and possibly cease operations. 4 WE HAVE HAD A LIMITED OPERATING HISTORY AS ANOT ACHIEVED SUBSTANTIAL REVENUE FROM SOFTWARE PRODUCT COMPANY AND LACK ANY SUBSTANTIAL REVENUE.SALES. We have a limited operating history as a software product company and have madehad only limited sales of our products. Our total revenues for software licenses for the yearyears ended December 31, 19982000 and for1999 and the nine months ended September 30, 19992001 were $569,000$978,000, $260,000 and $186,000,$720,000, respectively. The majority of our revenues to date have been derived from consulting services. 5 OUR REVENUES DEPEND ON SALES OF OUR CYBERWALLPLUS(TM)CYBERWALLPLUS PRODUCTS AND WE ARE UNCERTAIN WHETHER THERE WILL BE BROAD MARKET ACCEPTANCE OF THESE PRODUCTS. Our revenue growth for the foreseeable future is largely dependent upon increased sales of our CYBERWALLPLUS(TM)CYBERWALLPLUS family of software products. Since the introduction of our predecessor line of security producTS (Firewall/Plus) in June 1995 through September 30, 1999, license revenue from software products has been $2,848,000 including a non-refundable pre-paid royalty of $500,000 in 1997. Since the introduction of our CYBERWALLPLUS(TM)CYBERWALLPLUS suite of products in January 1999 through September 30, 1999,2001, license revenue from oUR CYBERWALLPLUS(TM)our CYBERWALLPLUS products was only $127,000.$1,887,000. Our future financial performance will depend upon the successfULsuccessful introduction and customer acceptance of our CYBERWALLPLUS(TM)CYBERWALLPLUS products as well as the development of new aNDand enhanced versions of this product. Revenue from products such as CYBERWALLPLUS(TM)CYBERWALLPLUS depend on a number of factorS,factors, including the influence of market competition, technological changes in the network security market, our ability to design, develop and introduce enhancements on a timely basis and our ability to successfully establish and maintain distribution channels. If we fail to achieve broad market acceptance of our CYBERWALLPLUS(TM)CYBERWALLPLUS products, ITit would have a material adverse effect on our business, operating results and financial condition. WE NEED TO HIRE A CHIEF EXECUTIVE OFFICER AND WE NEED TO ATTRACT AND RETAIN HIGHLY QUALIFIED TECHNICAL, SALES, MARKETING, DEVELOPMENT AND MANAGEMENT PERSONNEL. In June 2001, Avi Fogel resigned as our Chief Executive Officer, President and a Director. Murray Fish, our Chief Financial Officer, is serving as acting President. We are conducting a search for a new Chief Executive Officer. The market for hiring qualified Chief Executive Officer's in the network security field is highly competitive. If we are unable to hire and retain a qualified Chief Executive Officer, our business, operating results and financial condition could be materially adversely affected. Our success will also depend on our ability to attract, train and retain highly qualified technical, sales, marketing, development and management personnel. There is considerable and often intense competition for the services of such personnel. We may not be able either to retain our existing personnel or acquire additional qualified personnel as and when needed. If we are unable to hire and retain such personnel, our business, operating results and financial condition could be materially adversely affected. 5 WORLD INSTABILITY - TERRORISM. The recent terrorist attacks in the United States and the declaration of war by the United States against terrorism has created significant instability and uncertainty in the world which may continue to have a material adverse effect on world financial markets, including financial markets in the United States. In addition, such adverse political events may have an adverse impact on economic conditions in the United States. Unfavorable economic conditions in the United States may have an adverse effect on our financial operations including, but not limited to, our ability to expand the market for our products, obtain necessary financing, enter into strategic relationships and effectively compete in the network security market. OUR INABILITY TO ENTER INTO STRATEGIC RELATIONSHIPS WITH INDIRECT CHANNEL PARTNERS COULD HAVE A MATERIAL ADVERSE EFFECT ON US. As part of our sales and marketing efforts, we are seeking to develop strategic relationships with indirect channel partners, such as original equipment manufacturers and resellers. We have limited financial, personnel and other resources to undertake extensive marketing activities ourselves. Therefore, our prospects will depend on our ability to develop and maintain strategic marketing relationships with indirect channel partners and their ability to market and distribute our products. If we are unable to enter into and maintain such arrangements or if such arrangements do not result in the successful commercialization of our products, then this could have a material adverse effect on our business, operating results and financial condition. THE SALE OF OUR PROFESSIONAL SERVICES BUSINESS HAS HAD AN ADVERSE EFFECT ON CASH FLOW AND REVENUES. In February 2000, we sold our professional services business to Exodus Communications Inc. for $3.815 million in cash. As part of the transaction with Exodus, we agreed not to offer any professional or consulting services for two (2) years following the closing (February 2002). The professional services business accounted for 77% and 62% of our total revenues during the fiscal years ended December 31, 1999 and 1998, respectively. Accordingly, cash flow from operations has been and may continue to be materially adversely effected from the sale of our professional services business until, if ever, we generate sufficient revenue from the licensing of our software products. WE MAY NOT BE ABLE TO SUCCESSFULLY COMPETE IN THE NETWORK SECURITY MARKET. The network security market in general is characterized by intense competition and rapidly changing business conditions, customer requirements and technologies. The principal competitive factors affecting the market for network security products include security effectiveness, scope of product offerings, name recognition, product features, distribution channels, price, ease of use and customer service and support. Most of our current and potential competitors have longer operating histories, greater name recognition, larger installed customer bases and possess substantially greater financial, technical and marketing and other competitive resources than us. As a result, our competitors may be able to adapt more quickly to new or emerging technologies 6 and changes in customer requirements or to devote greater resources to 6 the promotion and sale of their products than we may. In addition, certain of our competitors may determine for strategic reasons to consolidate, to substantially lower the price of their network security products or to bundle their products with other products, such as hardware or other enterprise software products. Our current and potential competitors may develop products that may be more effective than our current or future products or that render our products obsolete or less marketable. Increased competition for network security products may result in price reductions and reduced gross margins and may adversely effect our ability to gain market share, any of which would adversely affect the Company's business, operating results and financial condition. OUR OPERATING RESULTS MAY FLUCTUATE QUARTERLY AND IF THEY WERE BELOW THE EXPECTATIONS OF INVESTORS AND ANALYSTS, THE PRICE OF OUR STOCK WOULD LIKELY BE ADVERSELY AFFECTED. We anticipate significant quarterly fluctuations in our operations in the future, since our results are dependent on the volume and timing of orders, which are difficult to predict. Customers' purchasing patterns and budgeting cycles, as well as the introduction of new products, may also cause our operating results to fluctuate. Therefore, comparing quarterly operating results may not be meaningful and should not be relied on. Also, our operating results may be below analysts' and investors' expectations in some future quarters, which would likely have a material adverse effect on our common stock's price. WE ARE DEPENDENT ON A FEW KEY PERSONNEL AND WE NEED TO ATTRACT AND RETAIN HIGHLY QUALIFIED TECHNICAL, SALES, MARKETING, DEVELOPMENT AND MANAGEMENT PERSONNEL. Our success is largely dependent on the continued service of key technical and senior management personnel. The loss of the services of one or more of our key employees, in particular Avi A. Fogel, our President and Chief Executive Officer, or Robert P. Olsen, our Vice President of Marketing, could have a material adverse effect on our business, operating results and financial condition. We have employment agreements with Messrs. Fogel and Olsen that expire in May 2002 and May 2001, respectively. Our success will also depend on our ability to attract, train and retain highly qualified technical, sales, marketing, development and managerial personnel. There is considerable and often intense competition for the services of such personnel. We may not be able either to retain our existing personnel or acquire additional qualified personnel as and when needed. If we are unable to hire and retain such personnel, our business, operating results and financial condition could be materially adversely affected. 7 WE MAY NOT BE ABLE TO ADEQUATELY PROTECT OUR PROPRIETARY TECHNOLOGY, WHICH COULD RESULT IN LOWER REVENUES AND/OR PROFITS. We do not hold any patents and rely on copyright and trade secret laws, non-disclosure agreements and contractual provisions to protect our proprietary technology. These methods afford only limited protection. Despite the precautions we take, unauthorized parties may attempt to copy or otherwise obtain and use our proprietary technologies, ideas, know-how and other proprietary information without authorization or may independently develop technologies similar or superior to our technologies. Policing unauthorized use of our products may be difficult and costly. Also, the laws of some foreign countries do not protect our proprietary rights as much as the laws of the United States. We are unable to predict whether our means of protecting our proprietary rights will be adequate. We believe that our technologies have been developed independent of others. Nevertheless, third parties may assert infringement claims against us and our technologies may be determined to infringe on the intellectual property rights of others. We could become liable for damages, be required to modify our technologies or obtain a license if our technologies are determined to infringe upon the intellectual property rights of others. We may not be able to modify our technologies or obtain a license in a timely manner, if required, or have the financial or other resources necessary to defend an infringement action. We would be materially adversely affectedeffected if we fail to do any of the foregoing. WE CAN BE EXPOSED TO NUMEROUS POTENTIAL LIABILITY CLAIMS FOR DAMAGES AND, IF OUR INSURANCE DOESN'T ADEQUATELY COVER LOSSES, THIS COULD HAVE A MATERIAL ADVERSE EFFECT ON US. Since our products are used to prevent unauthorized access to and attacks on critical enterprise information, we may be exposed to potential liability claims for damage caused as a result of an actual or alleged failure of an installed product. We cannot assure you that the provisions in our standard license agreements designed to limit our exposure will be enforceable. In addition, our consulting engagements often involve development, implementation and maintenance of networking systems that are critical to the operations of a client's business. Our failure to meet a client's expectations in the performance of our services could harm our reputation or result in a claim for damages. Our personnel often gain access to confidential and proprietary client information. Any unauthorized use or disclosure of such information could result in a claim for substantial damages. We can give no assurances that our insurance policies will be sufficient to cover potential claims or that adequate levels of coverage will be available in the future at a reasonable cost. 87 POSSIBLE DELISTING OF OUR SECURITIES FROM NASDAQ SYSTEM;NASDAQ; RISKS RELATING TO LOW-PRICED STOCKS. Our common stock is listed on theThe Nasdaq Stock Market's SmallCap Market under the symbol "NSSI." In order for our common stock to continue to be listed on Nasdaq, however, we must comply with certain maintenance standards. In the event of a delisting, an investor could find it more difficult to dispose of or to obtain accurate quotations as to the market value of our common stock. In addition, if our common stock were to become delisted from trading on Nasdaq and the trading price of theour common stock were to fallthen be below $5.00 per share, our common stock could be considered a penny stock. SEC regulations generally define a penny stock to be an equity security that is not listed on Nasdaq or a national securities exchange and that has a market value of less than $5.00 per share, subject to certain exceptions. The SEC regulations would require broker-dealers to deliver to a purchaser of our common stock a disclosure schedule explaining the penny stock market and the risks associated with it. Various sales practice requirements are also imposed on broker-dealers who sell penny stocks to persons other than established customers and accredited investors (generally institutions). Broker-dealers must also provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and monthly account statements disclosing recent price information for the penny stock held in the customer's account. If our common stock is no longer traded on Nasdaq and becomes subject to the regulations applicable to penny stocks, investors may find it more difficult to obtain timely and accurate quotes and execute trades in our common stock. OUR OPERATING RESULTS MAY FLUCTUATE QUARTERLY AND IF THEY WERE BELOW THE EXPECTATIONS OF INVESTORS AND ANALYSTS, THE PRICE OF OUR STOCK WOULD LIKELY BE ADVERSELY EFFECTED. We anticipate significant quarterly fluctuations in our operations in the future, since our results are dependent on the volume and timing of orders, which are difficult to predict. Customers' purchasing patterns and budgeting cycles, as well as the introduction of new products, may also cause our operating results to fluctuate. Therefore, comparing quarterly operating results may not be meaningful and should not be relied on. Also, our operating results may be below analysts' and investors' expectations in some future quarters, which would likely have a material adverse effect on the price of our common stock. 8 THE SIGNIFICANT NUMBER OF OPTIONS, WARRANTS AND CONVERTIBLE SECURITIES OUTSTANDING MAY ADVERSELY AFFECT THE MARKET PRICE FOROF OUR COMMON STOCK. As of the date of this prospectus, there are outstanding (1)(i) options and warrants to purchase an aggregate of 2,743,74711,452,212 shares of our common stock at exercise prices ranging from $1.50$.70 to $9.66, (2) 491,803$10.125 and (ii) 3,422,091 shares of Series D Convertible Preferred Stockconvertible preferred stock which are convertible at any time into an equal number of6,773,551 shares of our common stock and (3) debt in the principal amount of $1,500,000 which, subject to stockholder approval, can be converted into 491,803 shares of our Series D Preferred Stock (up to 570,492 shares if you include potential interest under the promissory notes) and warrants to purchase 491,803 shares of our common stock (up to 570,492 shares if you include potential interest under the promissory notes) at an exercise price of $3.00 per share, subject to adjustment.stock. To the extent that outstanding options and warrants or convertible debt are exercised or converted, your percentage ownership will be diluted and any sales in the public market of the common stock underlying such options, warrants or convertible debt may adversely affect prevailing market prices for our common stock. 9 WE HAVE A SIGNIFICANT AMOUNT OF AUTHORIZED BUT UNISSUED PREFERRED STOCK, WHICH MAY AFFECT THE LIKELIHOOD OF A CHANGE OF CONTROL IN OUR COMPANY. As of the date of this prospectus, our Board of Directors has the authority, without further action by the stockholders, to issue 5,000,00010,000,000 shares of preferred stock (of which only 491,803231,054 shares of Series D Preferred Stock are outstanding asand 3,191,037 shares of the date hereof)Series E Preferred Stock are outstanding) on such terms and with such rights, preferences and designations as the Board may determine. Such terms may include restricting dividends on our common stock, dilution of the voting power of our common stock or impairing the liquidation rights of the holders of our common stock. Issuance of such preferred stock, depending on the rights, preferences and designations thereof, may have the effect of delaying, deterring or preventing a change in control. In addition, certain "anti-takeover" provisions in Delaware law may restrict the ability of outour stockholders to authorize a merger, business combination or change of control.

The selling stockholders may sell the shares in transactions in the over-the-counter market, in negotiated transactions, or a combination of such methods of sale. The selling stockholders may sell the shares through public or private transactions at prevailing market prices, at prices related to such prevailing market prices or at privately negotiated prices. The selling stockholders may also sell shares pursuant to Rule 144 of the Securities Act, if applicable. The selling stockholders may use underwriters or broker-dealers to sell the shares. Such underwriters and broker-dealers may receive compensation in the form of discounts or commissions from the selling stockholders, or they may receive commissions from the purchasers of shares for 21 whom they acted as agents, or both (which compensation as to a particular broker-dealer might be in excess of customary commissions). The selling stockholders and any underwriter or broker-dealer who participates in the distribution of the shares may be deemed to be "underwriters" within the meaning of the Securities Act, and any commissions received by them and any profit on the resale of the shares purchased by them may be deemed to be underwriting discounts or commissions under the Securities Act. In addition, the broker-dealers' commissions, discounts or concession may qualify as underwriters' compensation under the Securities Act. We will disclose in a post-effective amendment to the registration statement any broker-dealers the selling stockholders contract with in the selling effort who may appear to be acting as underwriters within the meaning of Section 2(11) of the Securities Act. If any such broker-dealers are acting as underwriters, we will revise the disclosures in the registration statement to include the amount of the shares of our common stock being sold by the broker-dealer and, if the broker-dealer is entitled to sell additional shares, the broker-dealer's relationship and obligations to us and the selling stockholders and any associated expenses which we or the selling stockholders may incur in connection with such sale of our common stock. We will also file any agreement we or the selling stockholders may enter into with such broker-dealer as an exhibit to the registration statement. Under applicable rules and regulations under the Exchange Act, any person engaged in a distribution of the shares may not simultaneously engage in market-making activities with respect to our common stock for a certain period of time, except under certain limited circumstances. Also, without limiting the foregoing, each selling stockholder and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and rules and regulations thereunder (including Regulation M), which provisions may limit the timing of purchases and sales of shares of our common stock by such selling stockholder. At the time a selling stockholder makes an offer to sell shares, to the extent required by the Securities Act, a prospectus will be delivered. If a supplemental prospectus is required, one will be delivered setting forth the number of shares being offered and the terms of the offering, including the names of any underwriters, dealers or agents, the purchase price paid by any underwriter for the 22 shares, and any discounts or commissions. In order to comply with the securities laws of certain states, if applicable, the shares will be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and complied with. We have agreed to pay substantially all of the expenses incident to the registration, offering and sale of the shares to the public, excluding the commissions or discounts of underwriters, broker-dealers or agents. 22 LEGAL MATTERS The validity of the securities offered hereby will be passed upon for us by Solovay Edlinthe law firm of Olshan Grundman Frome Rosenzweig & Eiseman, P.C.,Wolosky LLP, 505 Park Avenue, New York, New York.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us, we have been advised that it is the SEC's opinion that such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. 23 NETWORK-1 SECURITY SOLUTIONS, INC. 3,278,29614,534,148 SHARES OF COMMON STOCK ------------------ PROSPECTUS ----------------------------------- ________, 20002002 PART II.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 145 of the Delaware General Corporations Law (the "DGCL") contains provisions entitling the Company's directors and officers to indemnification from judgments, fines, amounts paid in settlement, and reasonable expenses (including attorneys' fees) as the result of an action or proceeding in which they may be involved by reason of having been a director or officer of the Company. In its Certificate of Incorporation, the Company has included a provision that limits, to the fullest extent now or hereafter permitted by the DGCL, the personal liability of its directors to the Company or its stockholders for monetary damages arising from a breach of their fiduciary duties as directors. Under the DGCL as currently in effect, this provision limits a director's liability except where such director (i) breaches his duty of loyalty to the Company or its stockholders, (ii) fails to act in good faith or engages in intentional misconduct or a knowing violation of law, (iii) authorizes payment of an unlawful dividend or stock purchase or redemption as provided in Section 174 of the DGCL, or (iv) obtains an improper personal benefit. This provision does not prevent the Company or its stockholders from seeking equitable remedies, such as injunctive relief or rescission. If equitable remedies are found not to be available to stockholders in any particular case, stockholders may not have any effective remedy against actions taken by directors that constitute negligence or gross negligence. The Certificate of Incorporation also includes provisions to the effect that (subject to certain exceptions) the Company shall, to the maximum extent permitted from time to time under the law of the State of Delaware, indemnify, and upon request shall advance expenses to, any director or officer to the extent that such indemnification and advancement of expenses is permitted under II-1 such law, as it may from time to time be in effect. In addition, the Bylaws require the Company to indemnify, to the full extent permitted by law, any director, office, employee or agent of the Company for acts which such person reasonably believes are not in violation of the Company's II-1 corporate purposes as set forth in the Certificate of Incorporation. At present, the DGCL provides that, in order to be entitled to indemnification, an individual must have acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the Company's best interests. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to any charter, provision, by-law, contract, arrangement, statute or otherwise, the Company has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.
