SUMMARY NX NETWORKS We are a worldwide provider of internet telephony and data networking products and services. Our products are designed to deliver multi-service networks for the transport of voice and data that enable our customers to provide a wide variety of voice and data services. We combine patented, switched, compressed voice technology and advanced networking capabilities to provide networking solutions that improve network performance and deliver an array of tariffable network services. We were incorporated in Virginia in October 1985, and reincorporated in Delaware in March 1987. Our principal executive offices are located at 13595 Dulles Technology Drive, Herndon, Virginia 20171, and our telephone number is (703) 742-6000. RISK FACTORS THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. BEFORE INVESTING IN THE COMMON STOCK, YOU SHOULD CONSIDER CAREFULLY THE FOLLOWING RISK FACTORS, IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS. OUR BUSINESS AND RESULTS OF OPERATIONS COULD BE SERIOUSLY HARMED BY ANY OF THE FOLLOWING RISKS. THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE DUE TO ANY OF THESE RISKS, AND YOU COULD LOSE PART OR ALL OF YOUR INVESTMENT. TO DATE, WE HAVE INCURRED SUBSTANTIAL NET LOSSES, AND IF THIS CONTINUES, WE MAY BE UNABLE TO MEET OUR WORKING CAPITAL REQUIREMENTS For the years ended December 31, 1999 and 1998, respectively, we incurred net losses of approximately $26.2 million and $6.5 million and, on a pro forma basis, after giving effect to our December 1999 merger with OpenRoute Networks, Inc. and our March 2000 acquisition of AetherWorks Corporation, we would have had a net loss of approximately $94.5 million for the year ended December 31, 1999. Through September 30, 2000, we have incurred additional losses of approximately $88.5 million. These losses present a significant risk to our stockholders. If we cannot achieve profitability or positive cash flows from operating activities, we may be unable to meet our working capital and other payment obligations, which would have a material adverse effect on our business, financial condition and results of operation and the price of our common stock. In addition, if we cannot return to sustained profitability we will be forced to sell all or part of our business, liquidate or seek to reorganize. WE REQUIRE ADDITIONAL CAPITAL TO CONTINUE OUR OPERATIONS, AND WE CANNOT BE CERTAIN THAT THE NECESSARY FUNDS WILL BE AVAILABLE Our ability to return to and maintain profitability is largely dependent upon our ability to introduce new products and technologies and expand our sales efforts in new geographic and product markets. These activities require substantial capital, and if we do not have access to sufficient funds, either from our own operations or through third party financing, our ability to make these necessary expenditures will be limited. Also, if our stockholders do -2- not approve some of the proposals we present to them at our scheduled March 6, 2001 Special Meeting of Stockholders, we will be required to make significant cash payments. These payments are described below under the caption "--If our stockholders do not approve proposals presented to them at our March 6, 2001 Special Meeting of Stockholders, we may have substantial additional cash payment obligations in March 2001 and September 2001, and we do not currently have sufficient capital to pay these obligations." Our current available cash and our anticipated cash from operations are insufficient to fund our operations until we are able to attain profitability. Accordingly, we will require third party financing in order to continue our operations. We cannot assure you that we will be able to obtain financing on terms favorable to us, or at all. If we obtain additional funds by selling any of our equity securities, the percentage ownership of our stockholders will be reduced, stockholders may experience additional dilution, or the equity securities may have rights, preferences or privileges senior to the common stock. If we obtain additional funds by selling assets, we cannot assure you that we will be able to negotiate a favorable price for those assets or that the loss of those assets will not affect our future business prospects. If adequate funds are not available to us or available to us on satisfactory terms, we may be required to limit our marketing and product development activities or other operations, or otherwise modify our business strategy. These actions, if taken, could increase the difficulties we face in returning to sustained profitability. We have been advised by our independent public accountants that if we have not raised sufficient capital to meet our projected obligations for 2001 prior to the completion of their audit of our financial statements for the year ending December 31, 2000, their auditors' report on those financial statements will be modified to reflect this contingency. UNLESS OUR STOCKHOLDERS APPROVE PROPOSALS PRESENTED TO THEM AT OUR MARCH 6, 2001 SPECIAL MEETING OF STOCKHOLDERS, THE NUMBER OF SHARES OF COMMON STOCK THAT WE HAVE AVAILABLE FOR SALE TO RAISE CAPITAL IS LIMITED We have 55 million shares of authorized common stock, all of which are currently issued or reserved for issuance. Unless the number of authorized shares is increased, we will not be able to sell common stock to finance our operations or other obligations. We require additional funds to finance our operations, as described above under the caption "--We require additional capital to continue our operations, and we cannot be certain that the necessary funds will be available," and we may incur additional payment obligations in 2001 as described below under the caption "--If our stockholders do not approve proposals presented to them at our March 6, 2001 Special Meeting of Stockholders, we may have substantial additional cash payment obligations in March 2001 and September 2001, and we do not currently have sufficient capital to pay these obligations." We have called a meeting of stockholders for March 6, 2001 to vote upon a proposal to increase our capital stock from 55 million shares to 85 million shares. We cannot assure you that our stockholders will approve the increase in our authorized common stock. If our stockholders do not approve the increase in our authorized common stock, we will have to raise the necessary capital through debt financing or the sale of assets or securities other than common stock. Although we cannot assure you that we will be able to obtain the necessary funds if the stockholders approve the increase in our authorized number of shares of common stock, we believe it will be much more difficult for us to obtain the necessary financing if we cannot sell additional shares of common stock. IF OUR STOCKHOLDERS DO NOT APPROVE PROPOSALS PRESENTED TO THEM AT OUR MARCH 6, 2001 SPECIAL MEETING OF STOCKHOLDERS, WE MAY ISSUE SHARES THAT CAUSE US TO BE DELISTED FROM THE NASDAQ STOCK MARKET At our March 6, 2001 Special Meeting of Stockholders, we will ask our stockholders to authorize us to issue shares of common stock in private transactions which together with other shares we have issued would exceed 20% of our outstanding common stock. The listing requirements of the Nasdaq Stock -3- Market, on which our common stock is listed, will not permit us to issue more than 20% of our common stock in private transactions without stockholder approval if the sales price is less than the greater of the book or market price of our common stock. As of November 30, 2000, the book value per share of our common stock was approximately $2.66 and since December 16, 2000 the market value of our common stock has fluctuated between $0.50 and $3.06 per share. We cannot assure you that we will be able to raise the capital we need to fund our operations and other obligations without selling shares below the greater of our book value per share or market value per share. If our stockholders do not approve this proposal but they do authorize the increase in the number of authorized shares of common stock, we expect that we would sell the shares necessary to finance our operations and then be delisted from the Nasdaq Stock Market. Delisting from the Nasdaq Stock Market would have an adverse effect on the trading market for our common stock and the price of our common stock. IF OUR STOCKHOLDERS DO NOT APPROVE PROPOSALS PRESENTED TO THEM AT OUR MARCH 6, 2001 SPECIAL MEETING OF STOCKHOLDERS, WE MAY HAVE SUBSTANTIAL ADDITIONAL CASH PAYMENT OBLIGATIONS IN MARCH 2001 AND SEPTEMBER 2001, AND WE DO NOT CURRENTLY HAVE SUFFICIENT CAPITAL TO PAY THESE OBLIGATIONS At our March 6, 2001 Special Meeting of Stockholders, we will ask our stockholders to authorize us to issue 1.75 million shares of common stock related to our acquisition of AetherWorks Corporation. Under the listing requirements of the Nasdaq Stock Market, on which our common stock is listed, we cannot issue more than 20% of our common stock in an acquisition transaction without stockholder approval. This 1.75 million shares represents the amount by which the shares we have agreed to issue to the former owners of AetherWorks exceeds this 20% limitation. We agreed with the former owners of AetherWorks Corporation that if our stockholders do not approve the issuance of the 1.75 million shares, then we will pay the former owners of AetherWorks the cash value of those shares. The cash value per share will be the greater of $2.93 or the average last sales price for our common stock for the five trading days preceding March 6, 2001. Based solely on the $2.93 figure, this payment will be at least $5.1 million. In addition, we agreed with the recent purchasers of our preferred stock and related warrants that if our stockholders do not increase the number of our authorized shares of common stock to at least 65 million by September 2001, then we will redeem the preferred stock and warrants. The redemption price will be the liquidation value of the preferred stock and, for each share of common stock issuable upon conversion of the preferred stock or the warrants, 110% of the amount, if any, by which the price of our common stock at the redemption date exceeds the conversion or exercise price of the related preferred stock or warrants. Based solely on the liquidation preference of the preferred stock we have issued, this payment will be at least $2.5 million. The terms of the preferred stock and the warrants are described more fully under the caption "Recent Developments -Private Financing" below. We cannot assure you that our stockholders will approve these proposals. If we become obligated to pay these amounts in cash, we cannot assure you that we will be able to fund these obligations. Also, if our stockholders do not approve these proposals, it may become more difficult for us to obtain financing on terms favorable to us because many investors will be reluctant to invest if the proceeds from their investment are used to pay obligations to other investors. WE RELY TO A LARGE EXTENT ON INDEPENDENT DISTRIBUTION CHANNELS AND THE LOSS OF A SIGNIFICANT NUMBER OF DISTRIBUTORS COULD ADVERSELY EFFECT US We rely on reseller channels, including distributors and systems integrators, for a significant portion of our revenues. In particular, in foreign markets we often have one distributor designated for an entire country, and that distributor provides local support and service for our products. The loss of one or more significant resellers could adversely affect our business in terms of: o lost revenues; -4- o lost market presence; and o the difficulties we would encounter in servicing customers introduced to us by our resellers if we do not have other resellers in that geographic area. WE ARE EXPOSED TO POTENTIAL DELAYS IN PRODUCT SHIPMENTS BECAUSE WE CONTRACT OUT PRODUCT MANUFACTURING AND SOME COMPONENTS FOR OUR PRODUCTS ARE AVAILABLE ONLY FROM A SINGLE SUPPLIER OR A LIMITED NUMBER OF SUPPLIERS We rely on others to manufacture our products and product components and this dependence exposes us to potential interruptions or delays in product delivery. An interruption could have a short- term effect on our revenues and a longer term effect on our ability to market our products. Currently, we rely on a single contract manufacturer to assemble and test our voice products. Also, some of the components we use in our products are available from only one source or a limited number of suppliers. Although we have been able to obtain our products and these components to date, our inability to develop alternative sources if and as required in the future, or to obtain sufficient sole source or limited source components as required, could result in delays or reductions in product shipments. WE HAVE A SIGNIFICANT PAYMENT OBLIGATION TO OUR PRIMARY MANUFACTURER, AND IF WE DO NOT MAINTAIN OUR PAYMENT SCHEDULE THE MANUFACTURER MAY CEASE SHIPPING OUR PRODUCTS We authorized our primary manufacturer to purchase a substantial amount of parts, materials and long lead-time items during 2000 in anticipation of a significant increase in product sales during the year. Our sales did not reach the levels we expected, and we have not utilized a substantial amount of the raw materials. Accordingly, we have a payment obligation of approximately $5.5 million to the manufacturer to pay for the cost of these materials. We have agreed upon a payment schedule with the manufacturer, and during the period we are paying down the obligation the manufacturer is requiring us to pay in advance for all fabrication costs. If we do not adhere to the payment schedule or if we do not pay fabrication costs in advance, the manufacturer has expressed its intent not to ship any products on our behalf. Although we expect to have sufficient capital to maintain this payment schedule and pay the fabrication costs, if we do not adhere to the schedule and the manufacturer ceases to ship products on our behalf, then a material and adverse result to our revenues could occur. OUR BUSINESS WILL SUFFER IF WE LOSE CERTAIN KEY PERSONNEL OR FAIL TO ATTRACT AND RETAIN OTHER QUALIFIED PERSONNEL The success of our business is dependent, to a significant extent, upon the abilities and continued efforts of our management, sales and engineering personnel, many of whom would be difficult to replace. We do not have employment contracts with all of our key employees and we do not have "key man" life insurance on any of our officers or directors. Our success will also depend on our ability to attract, retain and motivate qualified management, sales and engineering executives and other personnel who are in high demand and who often have multiple employment options. In addition, as a result of the changes to technology-based industries, and particularly telecommunications companies, over the past year, many employees that we would like to retain may decide to pursue other opportunities or we may be forced to increase their compensation to retain them. The loss of the services of key personnel, or the inability to attract, retain and motivate qualified personnel, could have a material adverse effect on our business, financial condition, results of operations and the price of our common stock. -5- OUR INTELLECTUAL PROPERTY RIGHTS ARE AN IMPORTANT PROTECTION FOR OUR PRODUCTS, AND WE COULD BE ADVERSELY AFFECTED IF OUR RIGHTS ARE CHALLENGED OR CIRCUMVENTED BY COMPETITORS Our ability to compete successfully within our industry is dependent in part upon: o patents and nondisclosure agreements that we have obtained; o technical measures that we take to protect confidential information; and o trade secret, copyright and trademark laws that we rely on to establish and protect our proprietary rights. If any of our proprietary rights are successfully challenged or circumvented by competitors, or if other companies are able to market functionally similar products, systems or processes without infringing our proprietary rights, then our results of operations and the value of our common stock could be materially and adversely affected. THE MARKET PRICE OF OUR COMMON STOCK IS VOLATILE The market price of our common stock has been and can be expected to be significantly affected by factors such as: o quarterly variations in our results of operations; o the announcement of new services or service enhancements by us or our competitors; o technological innovations by us or our competitors; o changes in earnings estimates or buy/sell recommendations by analysts; o the operating and stock price performance of other comparable companies; and o general market conditions or market conditions specific to particular industries. In particular, the stock prices for many companies in the telecommunications equipment sector have experienced wide fluctuations that have often been unrelated to their operating performance. We have been, and we are likely to continue to be, subject to such fluctuations. WE RECENTLY REPRICED SUBSTANTIALLY ALL OF OUR STOCK OPTIONS TO A LOWER EXERCISE PRICE, AND THE RESULTING ACCOUNTING CHARGES MAY CAUSE OUR FUTURE EARNINGS TO FLUCTUATE WIDELY As part of a program to retain our employees, we adopted a program to reprice all the options of our current employees. We also repriced the options issued to our board of directors and to our chairman of the board. Under the program, each of these persons will exchange their current stock options for newly issued stock options with an exercise price of $0.75 per share. Although each employee may elect not to participate in the program, we expect that approximately 10 million options will be exchanged to obtain the lower exercise price. Under applicable accounting rules, we will have to account for future variations in the price of our common stock above $0.75 per share as compensation expense until the repriced options are either exercised, cancelled or expire. This calculation will be made each quarter based upon the performance of our common stock in that quarter. Accordingly, our operating results and earnings per share will be subject to potentially significant fluctuations based upon changes in the market price of our common stock. -6- OUR CERTIFICATE OF INCORPORATION AND BY-LAWS CONTAIN PROVISIONS THAT COULD DELAY OR PREVENT A CHANGE IN CONTROL Provisions of our certificate of incorporation and by-laws may have the effect of discouraging, delaying or preventing a take-over attempt that could be in the best interests of our stockholders. These include provisions that: o separate our board of directors into three classes; o limit the ability of our stockholders to call special stockholder meetings; o require advance notice of nominations for directors and stockholder proposals to be considered at stockholder meetings; and o require a vote greater than two-thirds to remove directors from office or amend many of the provisions of our certificate of incorporation and by-laws. Our board of directors also has the right, without further action of the stockholders, to issue and fix the terms of preferred stock, which could have rights senior to the common stock. We are also subject to the "business combination" provisions of the Delaware General Corporate Law, which impose procedures impeding business combinations with "interested stockholders" that are not approved of by our board of directors. RAPIDLY CHANGING TECHNOLOGY MAY MAKE OUR PRODUCTS OBSOLETE OR UNMARKETABLE We have focused our products on the edge of the Internet and telephony. This market is characterized by rapid technological change, frequent new product introduction and evolving industry standards. The introduction of products embodying new technologies by our competitors and the emergence of new industry standards could render our existing products obsolete and could cause new products to be unmarketable. Under these circumstances, our revenue would be adversely affected. Our success will depend on the ability to address the increasingly sophisticated needs of customers, to enhance existing products and to develop and introduce, on a timely basis, new competitive products that keep pace with technological development and emerging industry standards. If we cannot successfully identify, manage, develop manufacture or market products enhancements or new products, our business will be materially and adversely effected. WE HAVE ADOPTED A NEW MANAGEMENT INFORMATION SYSTEM AND IF WE CANNOT INTEGRATE THIS SYSTEM WE MAY HAVE DIFFICULTY EFFECTIVELY MANAGING OUR BUSINESS AND PREPARING TIMELY FINANCIAL REPORTS We adopted a new comprehensive management information system, and we are still in the process of implementing the installation and integrating the operations of OpenRoute and AetherWorks, the companies we acquired in December 1999 and March 2000. If we are unable to fully implement and integrate this system, we could have difficulties in preparing and maintaining the systems and reports we need to effectively manage our business and ensure timely financial reporting. These difficulties could result in adverse effects on our business. A PORTION OF OUR REVENUES ARE DERIVED FROM INTERNATIONAL SALES, WHICH ARE SUBJECT TO FOREIGN REGULATORY STANDARDS AND CURRENCY EXCHANGE RATE FLUCTUATIONS International sales accounted for 47% and 53% of our total revenues in 1999 and 1998, respectively, and international sales will continue to be significant to us. The conduct of international operations subjects us to certain risks. Foreign regulatory bodies continue to establish standards different from those in the United States, and our products are designed -7- generally to meet those standards. Our inability to design products in compliance with such foreign standards could have an adverse effect on our operating results. Also, our international business may be affected by changes in demand resulting from fluctuation in currency exchange rates and tariffs and difficulties in obtaining export licenses. We do not expect that we will hedge against fluctuations in currency exchange rates. RECENT DEVELOPMENTS NEW EXECUTIVES On January 8, 2001, John DuBois succeeded Steven Francesco as our chief executive officer. Mr. Francesco had resigned as chief executive officer on November 3, 2000. In connection with accepting the position, Mr. DuBois entered into a three-year employment agreement with us and he also became a member of our board of directors. The term of Mr. DuBois' agreement is through January 3, 2004. Under the agreement, Mr. DuBois is paid a base salary of $260,000 per annum, and he is eligible for quarterly and annual bonuses at the sole discretion of the board of directors. In addition, Mr. DuBois has been issued options to purchase 3,200,000 shares of common stock. 500,000 of the options have vested and the remainder vest over the term of his employment contract. Mr. DuBois exercised the 500,000 vested options upon signing his agreement. Mr. DuBois' employment agreement also provides that, in the event of a change in control of the Company, he will be issued 400,000 shares of common stock. In the event we terminate Mr. DuBois' employment without cause or Mr. DuBois terminates his employment for good reason, as these terms are described in the employment agreement, he will be entitled to: (1) receive an amount equal to 12 months base salary; (2) accelerated vesting of all of his stock options; and (3) participation in our benefit plans for up to 12 months. Mr. DuBois' employment agreement also contains non-compete provisions for up to one year after termination of his employment, that relate to the manner in which his employment is terminated. If the payment to Mr. DuBois upon termination or change of control results in the imposition of an excise tax pursuant to Section 280G of the Internal Revenue Code, we will pay to Mr. DuBois a tax "gross-up" payment equal to the amount of his resulting tax liability. At the time Mr. Francesco resigned as chief executive officer, he agreed that he would remain as a member of the board of directors only until December 2000. However, at the request of the board, he agreed to continue as Chairman of the Board and in support of Mr. DuBois and to provide such support to the Company as Mr. DuBois may request. On January 22, 2001, Steve Roberts joined us as our chief operating officer. Mr. Roberts did not enter into an employment agreement with us, but pursuant to the terms of his employment, we are paying him a salary of $220,000 per annum and we granted him stock options to purchase 1.0 million shares of our common stock, vesting over two years. On January 22, 2001, Heidi Heiden joined the board of directors, and on February 5, 2001 John Faccibene resigned from our board of directors. PRIVATE FINANCING On December 29, 2000, we raised $2.5 million from the sale 333,333 shares of preferred stock and 666,667 warrants in a private offering. The preferred stock bears a dividend of 8% per annum, which we can elect to pay in cash or shares of common stock, and the preferred stock has a liquidation preference equal to the purchase price per share plus the amount of any accrued but unpaid dividends. The preferred stock will become convertible into 3,333,330 shares of common stock and the warrants will become exercisable for 666,667 shares of common stock, if and when the amendment to our restated certificate of -8- incorporation to increase our authorized number of shares of common stock is approved by our stockholders. The conversion price of the preferred stock is $0.75 per share and the exercise price of the warrants is $0.90 per share, each of which is in excess of the last reported sales price of our common stock on the date the financing closed, $0.625 per share. If the amendment to our restated certificate of incorporation is not approved, the dividend rate on the preferred stock will increase by 1% per month and the exercise price of the warrants will decrease by 1% per month until this amendment is approved, commencing April 1, 2001. We further agreed with the purchasers of the preferred stock that if we have not increased our authorized capital stock to at least 65.0 million shares by September 30, 2001, then we will offer to repurchase all of the preferred stock for a purchase price equal to the liquidation amount plus 110% of the amount, if any, by which the market price of the common stock on that date exceeds the conversion price of the common stock, and we will redeem the warrants at a purchase price equal to 110% of the amount, if any, by which the exercise price of the warrants exceeds the market price of the common stock on that date. On January 17, 2001, we raised approximately $2.5 million from the sale 15,400 shares of preferred stock. The preferred stock bears a dividend of 8% per annum, which we can elect to pay in cash or shares of common stock, and the preferred stock has a liquidation preference equal to the purchase price per share plus the amount of any accrued but unpaid dividends. The preferred stock will become convertible into 1,540,000 shares of common stock, if and when the amendment to our restated certificate of incorporation to increase our authorized number of shares of common stock is approved by our stockholders. The conversion price of the preferred stock is $1.625 per share. If the amendment to our restated certificate of incorporation is not approved, the dividend rate on the preferred stock will increase by 1% per month until this amendment is approved, commencing April 1, 2001. We further agreed with the purchasers of the preferred stock that if we have not increased our authorized capital stock to at least 65.0 million shares by September 30, 2001, then we will offer to repurchase all of the preferred stock for a purchase price equal to the liquidation amount plus 110% of the amount, if any, by which the market price of the common stock on that date exceeds the conversion price of the common stock. AETHERWORKS STOCK ISSUE At the end of October 2000, we became obligated to issue to the former owners of AetherWorks Corporation shares of our common stock as a contractual adjustment to the number of shares we issued to them at the closing of the acquisition in March 2000. The adjustment was based upon a formula, and based upon our interpretation of the formula we announced in November 2000 that we would issue approximately 3.5 million additional shares of our common stock as the full adjustment, including actual shares and shares underlying warrants and non-compensatory options, but excluding options issued as compensation to employees. Based on our interpretation of the formula, we also announced that we expected to issue approximately 750,000 additional options as compensation to our employees who had been AetherWorks employees. After our announcement, we were contacted by the representatives of the former AetherWorks owners, and they informed us that they disagreed with our calculation of the adjustment. After discussion and negotiations, we reached an agreement to settle our dispute. Under the new agreement, we agreed to issue as the adjustment 4,777,973 shares of our common stock and options and warrants to acquire an additional approximately 654,000 shares of our common stock, excluding options issued as compensation to our employees. However, in order to comply with the listing requirements of the Nasdaq Stock Market, on which our common stock is listed, approximately 1.75 million of these shares can be issued only if our stockholders approve the issuance. In addition to these shares, we agreed to issue options to acquire an additional approximately 1,311,000 shares as compensation to our employees who had been AetherWorks employees. Pursuant to our agreement with the former owners of AetherWorks, we also agreed to reprice all of the options and warrants to have an exercise price of $1.60 per share, -9- except for one warrant for approximately 70,000 shares that we repriced to $1.33 per share. If our stockholders do not approve the issuance of the 1.75 million shares, then instead of issuing the 1.75 million shares, we will pay to the former AetherWorks owners the cash value of the shares. The cash value of the shares will be the greater of $2.93 or the average closing price of the common stock for the five trading days preceding the Special Meeting. CLAIMS AND PROCEEDINGS In November 2000, we were served with complaints in purported class action proceedings captioned TRACY REESE AND CHRISTINE JOYCE V. BRYAN HOLLEY, STEVEN T. FRANCESCO AND NX NETWORKS, INC., Civil Action No. 00-CV-11850-JLT, and MARC JACOBSEN V. BRYAN HOLLEY, STEVEN T. FRANCESCO AND NX NETWORKS, INC., Civil Action No. 00-CV-11999-JLT. Each complaint was originally filed September 2000 in the United States District Court for the District of Massachusetts. The complaints allege violation of the federal securities laws in connection with statements and disclosures made by the named defendants between December 8, 1999 and April 24, 2000. The complaints seek unspecified damages. We believe the allegations in the complaints are without merit, and we intend to vigorously defend ourselves in this litigation. In November 2000, we were served with a complaint in a purported class action proceeding captioned ROY WERBOWSKI V. NX NETWORKS, INC., STEVEN FRANCESCO AND PETER KENDRICK, Civil Case No. 00-1967-A. The complaint was originally filed in November 2000 in the United States District Court, Eastern District of Virginia. The complaint alleges that between July 27 and November 2, 2000 we breached securities laws in connection with the circumstances that led us to restate our financial statements for the quarter ended June 30, 2000. The complaint seeks unspecified damages. We believe we have meritorious defenses in this litigation, and we intend to vigorously defend ourselves. We have been advised that the plaintiffs are planning to consolidate their claims into a single complaint and a single action. Pending this event, we have not filed responses with the courts addressing the substantive allegations of the complaints. We believe that the outcome of the foregoing actions will not result in liability that would have a material adverse effect on our financial condition or results of operations. On November 8, 2000, the Enforcement Division of the SEC requested us to voluntarily provide documents related to the restatement of our financial statements for the quarter ended June 30, 2000. The SEC request advised us that the fact the SEC has made a request should not be taken as an indication that the SEC believes there has been a violation of law. We responded to the SEC request on November 20, 2000 and we have not been subsequently contacted. YEAR-END AND QUARTER-END REVENUE GUIDANCE On January 4, 2001, we announced that our revenues for 2000 would be approximately $27 million and our revenue for the quarter ended December 31, 2000 would be approximately $3.0 million. These unaudited results were lower than we expected. We believe these results reflect the general market conditions in our industry and also resulted from slippage of expected orders from the fourth quarter into 2001. The slippage of orders did not occur as a result of competitive pressure and therefore we expect these orders will be received in 2001. -10- WHERE YOU CAN FIND MORE INFORMATION We are subject to the informational requirements of the Exchange Act.

The Unaudited Pro Forma Condensed Consolidated Statements of Operations assume that the mergers with OpenRoute and AetherWorks were completed as of the beginning of the period presented. Certain reclassifications have been made to OpenRoute's and AetherWorks' financial statements to conform with Nx Networks presentation. Under the terms of the OpenRoute transaction, the holders of OpenRoute common stock and stock options received one share of Nx Networks common stock for each OpenRoute share converted. Under the terms of the AetherWorks transaction, it is assumed the holders of AetherWorks common stock, warrants, and stock options received an aggregate of 1.36 shares of Nx Networks Common Stock. ACCOUNTING TREATMENT Nx Networks recorded the OpenRoute and Aetherworks mergers as purchase transactions. For accounting purposes, Nx Networks is deemed to be the acquiring corporation in each merger. The pro forma adjustments are based upon currently available information and assumptions that Nx Networks management believes are reasonable and certain information provided by OpenRoute management and AetherWorks management. Nx Networks accounted for each merger based upon the estimated fair market value of the net tangible assets, intangible assets and liabilities acquired at the date of acquisition. The adjustments included in the Unaudited Pro Forma Condensed Consolidated Financial Statements represent the final determination of these adjustments based upon available information. Nx Networks cannot assure you that the actual values will not differ significantly from the pro forma adjustments reflected in the Unaudited Pro Forma Condensed Consolidated Financial Statements. For illustrative purposes, Nx Networks has made a preliminary allocation of excess cost over estimated net assets acquired to goodwill as AetherWorks' assets and liabilities are estimated to approximate fair value. For purposes of this Pro Forma Financial Information, Nx Networks assumed the price per share to be $22.50, as guaranteed in the merger agreement. Nx Networks engaged an independent third party to determine the amount of the excess purchase price related to purchased in-process research and development. The final allocation of purchase price to assets and liabilities acquired will depend upon the final purchase price and final estimates of fair values of assets and liabilities of AetherWorks at the closing date, Nx Networks will undertake a study to determine the fair values of assets and liabilities acquired and will allocate the purchase price accordingly. Nx Networks believes that the carrying value of current assets and current liabilities approximates fair value and that the excess of cost over historical net assets acquired will be allocated to property and equipment, in-process research and development, goodwill and other identifiable intangibles. However, there can be no assurance that the actual allocation will not differ significantly from the pro forma allocation. The Unaudited Pro Forma Condensed Consolidated Financial Statements are not necessarily indicative of either future results of operations or results that might have been achieved if the mergers with OpenRoute and AetherWorks had been consummated as of the indicated dates. The Unaudited Pro Forma Condensed Consolidated Financial Statements should be read in conjunction with the historical financial statements of Nx Networks, OpenRoute and AetherWorks, together with the related notes thereto, which are incorporated by reference into this registration statement. -15- NX NETWORKS INC.

DESCRIPTION OF SECURITIES. Not applicable. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL. Not applicable. II-1 ITEM 6. INDEMNIFICATION OF DIRECTOR AND OFFICERS. Section 145 of the Delaware General Corporation Law (the "DGCL") provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a "proceeding") (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with that action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. A Delaware corporation may indemnify any person under Section 145 who was, is or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure judgment in its favor, by reason of such fact as provided in the preceding sentence, against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of that action or suit, except that no indemnification shall be made in respect of the an action or suit if he did not act in good faith and in a manner he reasonably believed to be in or not opposed to our best interests and unless, and then only to the extent that, a court of competent jurisdiction shall determine upon application that he is fairly and reasonably entitled to indemnity for those expenses as the court shall deem proper. A Delaware corporation must indemnify any person who was successful on the merits or otherwise in defense of any action, suit or proceeding or in defense of any claim, issue or matter in any proceeding, by reason of such fact as provided in the preceding two sentences against expenses (including attorneys' fees) actually and reasonably incurred by him in connection the indemnified claim. A Delaware corporation may pay for the expenses (including attorneys' fees) incurred by an officer or director in defending a proceeding in advance of the final disposition to repay the amount advances if it shall ultimately be determined that he is not entitled to be indemnified by the corporation. Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director shall not be personally liable to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except for liability: (i) for any breach of the director's duty of loyalty to the corporation or its stockholders; (ii) for any acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) in respect of certain unlawful dividend payments or stock redemptions or repurchases; or (iv) for any transaction from which the director derived an improper personal benefit. The DGCL permits the purchase of insurance on behalf of directors and officers against any liability asserted against directors and officers and incurred by them in their capacity as an officer or director, or arising out of their status as an officer or director, whether or not the corporation would have the power to indemnify directors and officers against that liability. The Registrant has acquired officers' and directors' liability insurance of $1 million for members of our Board of Directors and executive officers. II-2 The Registrant's Certificate of Incorporation provides that the Registrant will indemnify all persons it is permitted to indemnify under the DGCL, and that this indemnification will be to the fullest extent permitted the DGCL.
