                                     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 stockholders do 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, there can be no assurance 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

                                      -2-


our outstanding common stock. The listing requirements of the Nasdaq Stock
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. The AetherWorks agreement underlying this obligation is
described more fully below under the caption "Selling Security Holders." 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:

                                      -3-


          o    lost revenues;

          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.

                                      -4-


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.

                                      -5-


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

                                      -6-


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.

         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

                                      -7-


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
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

                                      -8-


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,
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.

                SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

         Some of the information set forth in this prospectus includes "forward
looking statements" within the meaning of the Private Securities Litigation
Reform Act of 1995. In addition, from time to time, we may publish
"forward-looking statements" within the meaning of Section 27A of the Securities
Act and Section 21E of the Exchange Act or make oral statements that constitute
forward-looking statements. These forward-looking statements may relate to
matters such as anticipated financial performance, future revenues or earnings,
business prospectus, projected ventures, new products, anticipated market
performance and similar matters. The words "budgeted," "anticipate," "project,"
"estimate," "expect," "may," "believe," "potential" and similar statements are
intended to be among the statements that are forward looking statements. Because
these statements reflect the reality of risk and uncertainty that is inherent in
our business, actual results may differ materially from those expressed or
implied by the forward-looking statements. You are cautioned not to place undue
reliance on these forward looking statements, which are made as of the date of
this prospectus.

         The Private Securities Litigation Reform Act of 1995 provides a safe
harbor for forward-looking statements. In order to comply with the terms of the
safe harbor, we caution you that a variety of factors could cause our actual
results to differ materially from the anticipated results or other expectations
expressed in our forward-looking statements. These risks and uncertainties, many
of which are beyond our control, include, but are not limited to those set forth
under the caption "Risk Factors" on page 2 and in our filings with the SEC.

         We undertake no obligation to release publicly any revisions to the
forward looking statements to reflect events or circumstances after the date of
this prospectus or to reflect unanticipated events or developments.

                                 USE OF PROCEEDS

         We will not receive any proceeds from the sale of common stock by the
selling security holders. 237,613 shares of the common stock included in this
prospectus are issuable only upon the exercise of warrants held by the selling
security holders. If these warrants are exercised, we will be paid approximately
$362,000, reflecting the aggregate exercise price. We would apply these funds to
general working capital purposes.

                            SELLING SECURITY HOLDERS

         This prospectus relates to the resale of 7,317,022 shares of common
stock. The following table sets forth, to our knowledge:

          o    the number of shares of common stock beneficially owned by each
               of the selling security holders;

          o    the number of shares of common stock to be offered and sold by
               each of the selling security holders; and

          o    the number of shares of common stock and percentage of
               outstanding shares of common stock to be beneficially owned by
               each of the selling security holders after the offer and sale
               contemplated by this prospectus, assuming that all the shares
               offered by the selling security holder are in fact sold.

         To our knowledge, each person has sole investment and voting power,
with respect to the securities set forth in the following table.


                                      -11-


         As of January 12, 2001, we had approximately 41,721,000 shares of
common stock issued and outstanding.

(1)  Beneficial ownership is determined in accordance with the rules and
     regulations of the SEC and generally includes consideration of voting or
     investment power with respect to the securities at issue. Information with
     respect to beneficial ownership is based upon information as of January 12,
     2001 and assumes that there is outstanding an aggregate of 41,721,000
     shares of common stock, not including treasury shares.

(2)  Includes shares that may be acquired pursuant to warrants. For Messrs.
     Santos and Kaelin we have assumed they will elect to include their shares
     in our stock option repricing program. As a result, none of their options
     will be exercisable in the next 60 days.

(3)  Approximately 1.75 million of these shares will be sold only if our
     stockholders approve the issuance of those shares at the Special Meeting of
     Stockholders to be held on March 6, 2001. If the stockholders do not
     approve the issuance of these 1.75 million shares, the number of shares to
     be sold by each security holder will be reduced to reflect such holder's
     pro rata portion of the 1.75 million shares, and this prospectus will be
     amended accordingly.

(4)  Barry Romine is joint owner of the shares identified for Bradley, Ralph,
     Brett and Mary Catherine Romine.

         The 7,317,022 shares to which this prospectus relates were all issued
in connection with our acquisition of AetherWorks Corporation.

         In March 2000, we acquired all of the securities of AetherWorks
Corporation in exchange for shares of our common stock. At that time, we issued
2,301,436 shares of common stock and options and warrants exercisable for an
additional 867,687 shares, of which approximately 579,000 were compensation
related options issued to employees. The acquisition agreement also provided for
an increase in the number of shares we would have to issue if the average
closing price of our common stock on the Nasdaq National Market for the fifteen
trading day period ending October 31, 2000 did not equal or exceed $22.50 per
share. In this event, the acquisition agreement required us to issue additional
shares of our common stock to cause the consideration per share of AetherWorks
common stock to equal $22.50 per share based upon that average closing price,
provided that the total number of shares of our common stock issued in the
merger would not exceed 19.9% of our then total outstanding shares.

         Our common stock had an average closing price of $2.96 during the 15
day trading period, and the 19.9% cap became a limit on the number of shares we
would have to issue to the former owners of AetherWorks. Based upon our

                                      -15-



interpretation of the acquisition agreement, we announced 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 agreement, we also announced that
we expected to issue approximately 750,000 additional options as compensation to
our employees who had been AetherWorks employees.

         In November 2000, 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 with the former AetherWorks owners pursuant to which 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, in each case
subject to compliance with the Nasdaq Stock Market listing requirements. In
addition, we agreed to issue options to acquire an additional 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,
except for one warrant for approximately 70,000 shares that we repriced to $1.33
per share. Pursuant to an option repricing program we adopted for all of our
current employees on December 23, 2000, the options that were issued to persons
who are now employed with us will be repriced to an exercise price of $0.75 per
share.

         The listing requirements of the Nasdaq Stock Market prohibit us from
issuing more than 20% of our common stock in a merger transaction without
obtaining the consent of our stockholders. Under the Nasdaq rule, without
stockholder approval we can issue all but approximately 1.75 million of the
shares provided by the AetherWorks adjustment. We are calling a Special Meeting
of Stockholders at which we will ask our stockholders to authorize the issuance
of the additional 1.75 million shares. If our stockholders do not approve the
issuance of the additional 1.75 million shares, then the holders of the affected
securities have agreed that they will forego those securities in exchange for a
cash payment by us. For each share that is not authorized by our stockholders,
we have agreed to pay the greater of $2.93 or the average closing price of the
common stock for the five trading days preceding the special meeting.

                      SELECTED CONSOLIDATED FINANCIAL DATA

         The following selected consolidated financial data should be read in
conjunction with the our "Management's Discussion and Analysis of Financial
Condition and Results of Operations," our consolidated financial statements,
including the notes thereto, and our other financial data contained in this
prospectus and incorporated into this prospectus. The statement of operations
data and balance sheet data as of and for the years ended December 31, 1995,
1996, 1997, 1998 and 1999 are derived from the consolidated financial statements
of Nx Networks and the notes related thereto, which were audited by our
independent public accountants. The selected consolidated statement of
operations data and balance sheet data as of and for the nine month periods
ended September 30, 1999 and 2000 are derived from our unaudited consolidated
financial statements which, in the opinion of management, include all
adjustments necessary for a fair presentation of our financial condition and
results of operations for such periods. The results of operations for interim
periods are not necessarily indicative of a full year's operations. Net loss per
share is computed on the basis described in the notes to our consolidated
financial statements.

                   UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                              FINANCIAL STATEMENTS

         The following Unaudited Pro Forma Condensed Consolidated Statement of
Operations of Nx Networks for the nine months ended September 30, 2000 and the
year ended December 31, 1999 illustrate the effect of the mergers with OpenRoute
and AetherWorks. 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.

                            NOTES TO NX NETWORKS INC.
       UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS
         FOR THE NINE MONTHS ENDED SEPTEMBER 30, 2000 AND THE YEAR ENDED
                               DECEMBER 31, 1999

(1)  Information obtained from the historical unaudited consolidated statement
     of operations of Nx Networks.

(2)  Information obtained from the historical unaudited consolidated statement
     of operations of Aetherworks.

(3)  Reflects the amortization expense of goodwill and intangibles acquired in
     the merger of Aetherworks by use of the straight-line method over 4 years.

(4)  AetherWorks pro-forma adjustments excludes the one-time in-process research
     and development charges of $30.8 million in connection with the AetherWorks

(5)  Reflects a reduction in amortization of stock compensation expense for
     immediately vested options issued to Aetherworks employees.

(6)  Information obtained from the historical consolidated statement of
     operation of Nx Networks which includes OpenRoute from the date of
     acquisition, December 22, 1999.

(7)  Information obtained from the historical unaudited consolidated statement
     of operations of OpenROUTE from January 1, 1999 through the date of
     acquisition, December 22, 1999.

(8)  Information obtained from the historical statement of operations of
     AetherWorks for the year ended September 30, 1999 less the historical
     unaudited statement of operations of AetherWorks for the three months ended
     December 31, 1998 plus the historical statement of operations of

     assumed intrinsic value of stock options granted to AetherWorks' employees

     Networks common stock at an exercise price of $6.81 per share plus an
     immediate charge of $0.3 million. The compensation expense will be
     recognized over the options vesting period generally two to three years.
     The compensation expense reflected does not include the effects of the
     future issuance of options to acquire an additional 1,311,000 shares to the
     employees of Nx Networks who had been AetherWorks employees. In addition,
     the compensation expense does not reflect the repricing of the options
     negotiated in November 2000.

                              PLAN OF DISTRIBUTION

         The common stock may be offered and sold from time to time by one or
more of the selling security holders, or by their pledgees, donees, transferees
or other successors in interest. No selling security holder is required to offer
or sell any of his common stock. Sales may be made in one or more transactions
on the Nasdaq Stock Market or in negotiated transactions, or both. The selling
security holders may sell at marker prices at the time of sale, at prices
related to the market price or negotiated prices. The selling security holders
may sell shares to or through broker-dealers, and the broker-dealers may receive
compensation in the form of discounts, concessions or commissions from the
selling security holders and/or the purchasers of shares. The selling security

                                      -21-


holders and any broker-dealers that participate in the sale of the common stock
offered hereby may be deemed to be "underwriters" within the meaning of Section
2(11) of the Securities Act and any commissions and any profit on the resale of
the shares they receive may be deemed to be underwriting discounts and
commissions under the Securities Act. We have agreed to indemnify the selling
security holders against some liabilities, including under the Securities Act.

         All proceeds from the sale of the common stock will be paid directly to
the selling security holders and will not be deposited in an escrow, trust or
other similar arrangement. We will not receive any of the proceeds from the
sales of the common stock by the selling security holders. However, we will
receive proceeds from the exercise of the warrants, and these proceeds will be
approximately $362,000 if all of the warrants are issued.

         We will pay the legal, accounting and other fees and expenses related
to the offer and sale of the common stock contemplated by this prospectus,
excluding commissions charged by any broker or dealer acting on behalf of a
selling security holder. We estimate the fees and expenses will be $25,000.

                                  LEGAL MATTERS

         The validity of the common stock offered by this prospectus will be
passed upon for us by Kelley Drye & Warren LLP.

ITEM 15.  INDEMNIFICATION OF DIRECTORS 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

                                      II-1


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. We have acquired officers' and
directors' liability insurance of $1 million for members of our Board of
Directors and executive officers.

         At present, there is no pending litigation or other proceeding
involving any of our directors or officers for which indemnification is being
sought, and we are not aware of any threatened litigation that may result in
claims for indemnification by any officer or director.

         Article Eighth of our certificate of incorporation provides that we
will indemnify all persons we are permitted to indemnify under the Delaware
General Corporation Law, and that this indemnification will be to the fullest
extent permitted the Delaware General Corporation Law.

ITEM 17.  UNDERTAKINGS

         The undersigned registrant hereby undertakes:

          A.   To file, during any period in which offers or sales are being
               made, a post-effective amendment of this registration statement:

               (i)  To include any prospectus required by Section 10(a) (3) of
                    the Securities Act of 1933.

               (ii) To include in the prospectus any facts or events arising
                    after the effective date of the registration statement (or
                    most recent post-effective amendment thereof) which,
                    individually or in the aggregate, represent a fundamental
                    change in the information set forth in the registration
                    statement.

                                      II-5


               (iii) To include any material information with respect to the
                    plan of distribution not previously disclosed in the
                    registration statement or any material change to such
                    information in the registration statement.

          B.   That, for the purposes of determining any liability under the
               Securities Act of 1933, each such post-effective amendment shall
               be deemed to be a new registration statement relating to the
               securities offered therein, and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof.

          C.   To remove from registration by means of post-effective amendment
               any of the securities registered which remain unsold at the
               termination of the offering.

          D.   Insofar as indemnification for liabilities arising under the
               Securities Act of 1933 may be permitted to directors, officers
               and controlling persons of the registrant pursuant to any charter
               provisions, by-laws, contract, arrangements, statute or
               otherwise, the registrant has been advised that in the opinion of
               the Securities and Exchange Commission such indemnification is
               against public policy as expressed in the Act and is, therefore,
               unenforceable. In the event that a claim for indemnification
               against such liabilities (other than the payment by the
               registrant of expenses incurred or paid by a director, officer or
               controlling person of the registrant of expenses incurred or paid
               by a director, officer or controlling person of the registrant in
               the successful defense of any action, suit, or proceeding) is
               asserted by such director, officer or controlling person in
               connection with the securities being registered, the registrant
               will, unless in the opinion of its counsel the matter has been
               settled by a controlling precedent, submit to a court of
               appropriate jurisdiction the question whether such
               indemnification by it is against public policy as expressed in
               the Act and will be governed by the final adjudication of such
               issue.

          E.   Subject to the terms and conditions of Section 15(d) of the
               Securities Exchange Act of 1934, as amended, Netrix Corporation
               hereby undertakes to file with the Securities and Exchange
               Commission such supplementary and periodic information, documents
               and reports as may be prescribed by any rule or regulation of the
               Commission heretofore or hereafter duly adopted pursuant to
               authority conferred in that Section.

                                      II-6




                                   SIGNATURES

amended, Nx Networks, Inc. certifies that it has reasonable grounds to believe
