                                  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 OR CONTINUE AS A GOING
CONCERN

         For the years ended December 31, 2000 and 1999, respectively, we
incurred net losses of approximately $180.7 million and $26.2 million. Through
March 31, 2001, we have incurred additional losses of approximately $14.3
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. These factors raise
substantial doubt about our ability to continue as a going concern. Our
financial statements do not include any adjustments relating to the
recoverability and classification of asset carrying accounts or the amount and
classification of liabilities that might be necessary should we be unable to
continue as a going concern.

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. Our current available cash and our
anticipated cash from operations are insufficient to fund our operations until
we are able to attain profitability, and the audit report of our independent
public accountants reflects this contingency. 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 SIGNIFICANT ACCOUNTS PAYABLE TO CERTAIN OF OUR VENDORS, AND WE MUST
MANAGE OUR AVAILABLE CASH UNTIL WE HAVE SUFFICIENT CASH TO SATISFY ALL OF THE
DEMANDS FOR PAYMENT.

        Over the past six months, we have sought to raise capital in relatively
small increments in an effort to minimize the dilution to our stockholders
resulting from our capital raising efforts. Given the current state of the
financial markets and our own expectations regarding our ability to continue to
raise funds over the next  several  months,  we  continue  to believe  that this
approach is in the best interests of our



                                       3


creditors, customers and stockholders. However, as a consequence of our decision
to raise capital in small increments,  our accounts payable balance at any given
date is  significant  in relation to our available  cash balance.  This makes it
more difficult to satisfy the payment  demands of all of our vendors on a timely
basis and it makes it more difficult to convince  vendors that they will be paid
all amounts to which they are  entitled  despite  our low  balance of  available
cash.  If a large  number of our  vendors  demand  payment  in advance or demand
payment of all currently  outstanding  amounts  payable,  our business  could be
disrupted  because we do not have sufficient cash to fund all these  obligations
unless we raised additional funds and, accordingly, we would have to immediately
raise  additional  funds to satisfy  these payment  demands.  In addition to the
disruption  to our business,  seeking to raise capital under such  circumstances
would be even more difficult than the circumstances now facing us.

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;

        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 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, as of March 31, 2001, we have a payment obligation of
approximately $4.9 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. We
must raise additional capital to maintain this payment schedule and pay the
fabrication costs. If we are unable to raise sufficient capital to 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. Also, if the
manufacturer brings a legal action to collect the outstanding amount, we do not
have sufficient current financial resources to pay this obligation.

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



                                       4


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.

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.

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. In addition, legal proceedings
to enforce intellectual property rights are expensive given the technical nature
of the legal and functional analysis. Given our current financial condition, we
could experience difficulty funding enforcement of our intellectual property
rights.

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.



                                       5


        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.

OUR SERIES E CONVERTIBLE PREFERRED STOCK HAS A FLOATING CONVERSION PRICE, AND
THIS COULD RESULT IN DILUTION TO OUR STOCKHOLDERS AND DOWNWARD PRICE PRESSURE ON
OUR STOCK

        In May 2001 we sold 19,000 shares of Series E 8% convertible preferred
stock for an aggregate purchase price of $2.4 million. Each share of the Series
E preferred stock has an initial conversion price of $1.265 per share, and the
number of shares of common stock initially issuable under the terms of the
Series E preferred stock is 1.9 million shares. However, after an initial period
the conversion price of the Series E preferred stock will be fixed by reference
to the volume weighted average sales price (VWAP) of our common stock.
Specifically, the Series E preferred stock will have a conversion price per
share equal to the lesser of (1) $1.265 or (2) 87% of the VWAP during the five
days preceding a notice of conversion, subject to a minimum conversion price of
$0.575 per share. Accordingly, between the common stock prices of $1.46 and
$0.66, the number of shares of common stock we will have to issue upon
conversion of the Series E preferred stock will fluctuate. The range is between
1.9 million shares at a VWAP of $1.46 (reflecting a conversion price of $1.265
per share) to 4.2 million shares at a VWAP of $0.66 (reflecting a conversion
price of $0.575 per share).

        If the price of our common stock decreases over time, the number of
shares we will have to issue upon conversion of the Series E preferred stock
will increase. Sales of an increased number of shares of common stock issued
upon conversion of the Series E preferred stock as a result of a decline in our
common stock price can cause the market price of our common stock to decline
further.

        Short sales of our common stock may be attracted by or accompany the
sale of converted Series E preferred stock, which in the aggregate could cause
downward pressure upon the price of our common stock, regardless of our
operating results, market conditions or other factors. A decline in the price of
our common stock, in turn, could attract additional short sales of our common
stock and would result in additional shares becoming eligible for sale upon
conversion of the Series E preferred stock. This would put further downward
pressure on the price of our common stock.

OUR STOCK PRICE IS CURRENTLY BELOW THE MINIMUM THRESHOLD REQUIRED BY THE NASDAQ
STOCK MARKET, AND UNDER CURRENT NASDAQ RULES IF OUR STOCK PRICE DOES NOT RISE
AND/OR OUR TANGIBLE NET ASSETS DO NOT REACH $4.0 MILLION, WE MAY BE DELISTED BY
THE NASDAQ STOCK MARKET

        On May 24, 2001, the last reported bid price of our common stock on the
Nasdaq Stock Market was $0.96 per share, and our tangible net value per share
was less than $4.00. Under the current listing requirements of the Nasdaq
National Market, on which our common stock is listed for trading, our common
stock may be delisted if (1) we do not have a closing bid price of at least
$1.00 per share and tangible net assets per share of at least $4.0 million or
(2) we do not have a closing bid price of at least $5.00 per share. We do not
currently meet either of these listing requirements.

         Nasdaq has proposed to change the listing requirements to replace the
$4.0 million net tangible asset test with a $10.0 million stockholders' equity
test, but this change requires approval by the SEC. Nasdaq has notified us that
we are not in compliance with the net tangible asset test, but we do comply with
the proposed stockholders' equity test. Nasdaq also informed us that they are
not taking any action at this time with  respect  to our  listing,  pending  SEC
action on the proposed rule change. If the SEC does not approve the rule change,
and Nasdaq notifies us of the listing deficiency,  we must be in compliance with
the listing  requirements  for at least 10  consecutive  business days in the 90
calendar day period after we receive the Nasdaq notice.  If we fail to meet this
standard, then our common stock may be delisted from the Nasdaq National Market.
We expect that if we are delisted from the Nasdaq National Market,



                                       6


and our  common  stock is in  compliance  with the  $1.00  per  share  bid price
requirement, then we will list our shares on the Nasdaq SmallCap Market.

         If the closing bid price of our common stock is below $1.00 per share
for 30 consecutive trading days, then we expect Nasdaq will notify us we are not
in compliance with the listing requirements. If Nasdaq notifies us of a listing
deficiency related to the $1.00 minimum bid price requirement, we must be in
compliance with the listing requirements for at least 10 consecutive business
days in the 90 calendar day period after we receive the Nasdaq notice. If we
fail to meet this standard, then our common stock may be delisted from the
Nasdaq Stock Market. If we are delisted from the Nasdaq Stock Market, our common
stock will trade on the over-the-counter market.

        We expect that if we change from the Nasdaq National Market to the
Nasdaq SmallCap Market or the over-the-counter market, there will be an adverse
effect on the liquity and value of our common stock.

IN DECEMBER 2000 WE RE-PRICED 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
re-price the options of our current employees. We also re-priced the options
issued to our board of directors and to our chairman of the board. Under the
program, each of these persons exchanged their current stock options for newly
issued stock options with an exercise price of $0.75 per share. Approximately
7.3 million options were 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 re-priced 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. As of March 31, 2001, $100,000 of compensation expense
was recorded based on the performance of our common stock in that quarter.
Accordingly, our operating results and earnings per share are subject to
potentially significant fluctuations based upon changes in the market price of
our common stock.

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
affected.

OUR INDEPENDENT PUBLIC ACCOUNTANTS HAVE IDENTIFIED WEAKNESSES IN OUR FINANCIAL
SYSTEMS AND CONTROLS, AND IF WE DO NOT REMEDY THE WEAKNESSES, WE MAY HAVE
DIFFICULTY EFFECTIVELY MANAGING OUR BUSINESS AND PREPARING TIMELY FINANCIAL
REPORTS

        In connection with conducting the audit of our year 2000 financial
statements, our independent public accountants identified a number of
deficiencies in design and operation of our internal accounting controls.
Although our accountants did not qualify their audit opinion with respect to
these matters, they advised us that we must remedy the identified problems. If
we are unable to remedy the deficiencies identified by our accountants, 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 48% and 47% of our total revenues in
2000 and 1999, respectively, and 59% of our total revenues in the first quarter
of 2001. 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 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.

                                LEGAL PROCEEDINGS

LITIGATION

         Cabletron Systems, Inc. filed a civil complaint against AetherWorks
Corporation, OpenROUTE Networks, Inc. and Netrix Corporation (the Defendants) on
June 5, 2000 in the United States District Court for the District of
Massachusetts. Docket # 00-CV-11105 RWZ is assigned to this matter. In its
complaint, Cabletron alleges that the Defendants have infringed seven Cabletron
patents and Cabletron seeks monetary damages against the Defendants. We answered
the complaint by denying the allegations contained therein. Discovery is
underway. Cabletron has sought permission of the Court to amend its complaint to
increase the number of patents it alleges have been infringed, but this was
denied. We have notified certain of our equipment providers that we claim
indemnification from them because the infringements alleged by Cabletron appear
to relate to the equipment those suppliers provided to us.



                                       8


Based upon discussions with counsel and the information currently available to
us, we believe we have meritorious defenses to the claims by Cabletron, and we
will continue to vigorously defend this action.

         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. In May
2001, the plaintiffs filed an amended complaint consolidating the two actions
and dropping Mr. Holley as a defendant. The amended complaint alleges violation
of the federal securities laws in connection with statements and disclosures
made between December 8, 1999 and April 24, 2000. The complaints seek
unspecified damages. We believe the allegations in the amended complaint are
without merit, and we intend to vigorously defend ourselves in this litigation.
We have notified our insurance carrier regarding the claims.

         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. In May 2001, the plaintiffs filed an amended complaint. The amended
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 amended complaint
seeks unspecified damages. We believe we have meritorious defenses in this
litigation, and we intend to vigorously defend ourselves. We have notified our
insurance carrier regarding the claims.

         In January, 2001 we were served with a complaint captioned MANAGEMENT
INFORMATION CONSULTING, INC. ("MIC") V. NX NETWORKS, INC. This action was filed
in the Alexandria Division Court for the Commonwealth of Virginia, and the case
is assigned No. CL01-45. In the complaint, MIC claims entitlement to
approximately $150,000 in payment for web site development services performed by
it. We dispute that this amount is due, based upon the quality and quantity of
services provided by MIC. We have filed an answer denying the claims and we
intend to vigorously defend ourselves in this litigation.

         An action captioned K.S. TELECOM, INC. ("K.S. TELECOM") V. NX NETWORKS,
INC. was commenced in July, 2000 in the Southern District of New York, and it is
assigned case number 00 Civ. 3375 (KMW). In this action, we are named as a third
party defendant by K.S. Telecom under a number of legal theories in an action
brought against K.S. Telecom by Netrix Leasing, LLC, an unrelated entity. Netrix
Leasing LLC had purchased equipment from us and leased it to K.S. Telecom.
Netrix Leasing alleges that K.S. Telecom subsequently defaulted on the lease
payment obligations. In its third-party complaint, K.S. Telecom alleges that it
breached its lease because of our failure to properly prepare, install and
repair the equipment. In its complaint, K.S. Telecom seeks damages against us
equal to approximately $177,000 plus any amounts they are found to owe to Netrix
Leasing. Netrix Leasing is seeking approximately $550,000 pursuant to its
original complaint against K.S. Telecom, representing lease amounts past due of
approximately $78,000 and acceleration of future payments under the lease of
approximately $472,000. We responded to the third-party complaint of K.S.
Telecom by denying all of their allegations and we sought dismissal of the
claims in a summary judgment motion. On March 7, 2001, the court ruled that
certain of the claims against us must be dismissed, but that other claims may
proceed. Specifically, the court ruled that K.S. Telecom could proceed to try to
prove its allegation that it is a third party beneficiary of our agreements with
Netrix Leasing and that we breached obligations to K.S. Telecom under those
agreements. We believe we have meritorious defenses to the claims of K.S.
Telecom, and we intend to vigorously defend this action.



                                       9


         In January 2001, we were informed that a former employee in France has
obtained a trial court ruling in France related to his termination in 1997. The
amount of the award to him is approximately 800,000 French Francs, and using an
exchange rate into U.S. dollars of 7:1, this is approximately $100,000.
Approximately $25,000 of the amount represents payment of a disputed bonus, and
approximately $75,000 represents an award of punitive damages. We are appealing
this ruling because we believe the award of punitive damages is unjustified.

         In May 2001, we were served with a complaint captioned MANAGEMENT
RECRUITERS - MONTICELLO, L.L.C. V. NETRIX CORPORATION, Civil Case No. 00-1867-1.
The case was filed in the Circuit Court for the County of Albermarle in the
Commonwealth of Virginia. The complaint demands payment of approximately $50,000
for recruiting expenses allegedly incurred by us in 2000. We are reviewing the
complaint, and expect that we will settle this matter.

         In May 2001, we were served with a complaint captioned U.S. ASSEMBLIES
NEW ENGLAND, INC. V. OPENROUTE NETWORKS, INC. AND NETRIX CORPORATION D/D/A NX
NETWORKS, Civil Case No. BRCV 2001-00551A. The case was filed in the Superior
Court for the Commonwealth of Massachusetts in Bristol, Massachusetts. The
complaint alleges that we owe U.S. Assemblies approximately $1.0 million,
representing (1) claimed amounts for products delivered of $$700,000 less an
offset due us of $120,000, (2) $40,000 of work in process and (3) $360,000 for
inventory purchased on our behalf. We are reviewing the complaint, and have not
yet filed an answer. Based upon our initial review of the allegations set forth
in the complaint, we expect to deny entirely the allegations related to any
amounts for inventory purchased on our behalf and for work-in-process. We also
expect to dispute the amount claimed by U.S. Assemblies for products delivered
and to assert various other defenses to the claims by U.S. Assemblies. In
addition, we expect to assert counterclaims against U.S. Assemblies for breach
of contract related to production delays they incurred in manufacturing products
for us and for amounts payable by them to us. We will vigorously defend this
action.

         In addition to the above matters, we are periodically involved in
disputes arising from normal business activities. In our opinion, resolution of
these matters will not have a material adverse effect upon our financial
condition or future operating results, and adequate provision for any potential
losses have been made in our financial statements.

SECURITIES AND EXCHANGE COMMISSION INVESTIGATION

         The Securities and Exchange Commission has commenced an investigation
into the matters surrounding the Company's restatement of revenues for its
quarter ended June 30, 2000. For the quarter ended June 30, 2000, the Company
restated revenues from $10.4 million to $8.4 million for sales made to two of
its value added resellers ("VARs"). These sales were dependent upon the payment
to the VARs from their customers.

                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 3 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. Some of the shares that selling security holders have
registered for sale are shares that they can obtain only upon the exercise of
warrants they hold. In order to obtain the common stock underlying the warrants
for sale, these selling security holders must exercise the warrants. The
warrants have exercise prices ranging from $0.90 to $12.43 per share, and, if
all of the warrants are exercised, we will receive approximately $2.2 million.
We will use the proceeds from any warrant exercises for general corporate and
working capital purposes.





                                       12





                            SELLING SECURITY HOLDERS


        This prospectus relates to the sale of up to 16,206,469 shares of common
stock by the selling security holders. The number of shares of common stock that
may be offered for sale by the selling stockholders may vary from time to time
depending upon (1) the conversion price of our Series E convertible preferred
stock, which is dependent upon the market price of our common stock, and (2)
whether we elect to issue any shares of common stock as dividends upon our
Series B, Series C, Series D or Series E convertible preferred stock. The number
of shares offered by the selling stockholders pursuant to this prospectus may
not exceed 16,206,469.

        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.

        For purposes of preparing this table, we have assumed the Series E
convertible preferred stock will be converted at the lowest potential conversion
price and that we will not issue shares of common stock as payment of dividends
on our preferred stock. We have also assumed that each selling security holder
will sell all of the shares identified to be sold in this prospectus. The
selling security holders are not required to sell any of their shares in this
offering.

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

        As of May 15, 2001, we had approximately 44,412,000 shares of common
stock issued and outstanding.

         The Series C preferred stock bears a dividend of 8% per annum, which we
can elect to pay in cash or shares of common stock. Each share of Series B
preferred stock is convertible into shares of our common stock at a conversion
price of $1.625 per share, which represents one hundred shares of common stock
for every share of preferred stock. The Series C preferred stock has a
liquidation preference per share equal to the purchase price of that share, plus
the amount of accrued but unpaid dividends. The Series C preferred stock has no

         Each holder of the Series C preferred stock agreed not to sell any of
the shares of common stock underlying the preferred stock prior to June 30,
2001, unless the common stock reached certain levels in excess of the initial
conversion price of the Series C preferred stock. The levels at which the common
stock has to trade for 10 consecutive days and the number of shares which become
eligible for sale at such levels are:

         Common stock price              Number of shares that become tradeable
         ------------------              --------------------------------------
               $2.03                                    25%

                3.17                                    25%
                3.96                                    25%

The common stock has traded in excess of $2.03 for more than 10 consecutive days
since the issue date of the Series C preferred stock, so 25% of the shares are
currently eligible for sale.

         In connection with the Series C preferred stock offering, we paid fees
of $12,500 to Intercontinental Capital {LLC}. Intercontinental provided
consulting services to us related to the structure and marketing of the Series C
preferred stock offering.

million. We have applied these proceeds to fund operations.

         The Series D preferred stock bears a dividend of 8% per annum, which we
can elect to pay in cash or shares of common stock. Each share of Series D
preferred stock is convertible into shares of our common stock at a conversion
price of $1.41 per share, which represents one hundred shares of common stock

the shares of common stock underlying the preferred stock prior to June 30,
2001, unless the common stock reached certain levels in excess of the initial
conversion price of the Series D preferred stock. The levels at which the common
stock has to trade for 10 consecutive days and the number of shares which become
eligible for sale at such levels are:



                                       17


         Common stock price               Number of shares that become tradeable

              3.44                                       25%

The common stock has not yet met any of these thresholds.

         In connection with the sale of the Series D preferred stock, we issued
to each purchaser warrants to purchase the number of shares of common stock
equal to 20% of the number of shares of common stock the purchaser can obtain by
converting the Series D preferred stock purchased in the offering. The warrants
have a five-year term, and have an exercise price of $2.11 per share.

SHARES RELATED TO OUR SERIES E 8% CONVERTIBLE PREFERRED STOCK OFFERING

         Up to 4,180,000 of the shares offered hereby are issuable upon the
conversion of our Series E 8% convertible preferred stock. We sold the Series E
preferred stock on May 14, 2001 at $126.50 per share, and we received net
proceeds of approximately $2.2 million. We will apply these proceeds to fund
operations.

         The Series E preferred stock bears a dividend of 8% per annum, which we
can elect to pay in cash or shares of common stock. The Series E preferred stock
has a liquidation preference per share equal to the purchase price of that
share, plus the amount of accrued but unpaid dividends. The Series B preferred
stock has no voting rights, except to the extent required by applicable law. The
Series E preferred stock is redeemable by us at a repurchase price of $132.83
per share if the last reported sales price of our common stock is $5.00 or more
for ten consecutive trading days.

         Each share of the Series E preferred stock has an initial conversion
price of $1.265 per share, and the number of shares of common stock initially
issuable under the terms of the Series E preferred stock is 1.9 million shares.
However, from and after May 19, 2001 the conversion price of the Series E
preferred stock will be fixed by reference to the volume weighted average sales
price (VWAP) of our common stock. Specifically, the Series E preferred stock
will have a conversion price per share equal to the lesser of (1) $1.265 or (2)
87% of the VWAP during the five days preceding a notice of conversion, subject
to a minimum conversion price of $0.575 per share. Accordingly, between the
common stock prices of $1.46 (resulting in a conversion price of $1.265 per
share) and $0.66 (resulting in a conversion price of $0.575 per share), the
number of shares of common stock we will have to issue upon conversion of the
Series E preferred stock will fluctuate. The range is between 1.9 million shares
at a VWAP of $1.46 to 4.2 million shares at a VWAP of $0.66.

         In connection with the Series E preferred stock offering, we paid fees
of $120,000 to Avondale Capital Partners, Inc. and issued to them warrants to
purchase 24,000 shares of our common stock at an exercise price of $1.52 per
share. Avondale Capital introduced the investors to us and they indemnified us
with respect to their services under applicable securities laws.

         In connection with the sale of the Series E preferred stock, we issued
to each purchaser warrants to purchase the number of shares of common stock
equal to 20% of the number of shares of common stock the purchaser can obtain by
converting the Series E preferred stock purchased in the offering using a
conversion price of $1.265 per share. The warrants have a five-year term, and
have an exercise price of $1.438 per share.

        Pursuant to the Securities Purchase Agreement we entered into with the
purchasers of the Series E preferred stock:




                                       18


        o   The initial purchasers have a right of first offer and a right of
            participation, subject to certain conditions, in any financing we
            undertake prior to May 14, 2002.

        o   Each holder of Series E preferred stock is prohibited from engaging
            in direct or indirect sales transactions during the five trading day
            period preceding the date such buyer delivers a notice of conversion
            to us, unless the conversion price is at least $1.265 per share or
            we have previously given a notice of redemption for such shares.

PRIVATE PLACEMENT OF COMMON STOCK

         On March 28, 2001 we raised $2.0 million through a private placement of

SHARES ISSUED IN LIEU OF CASH PAYMENT

         The shares offered by Gallagher, Harnett & Lagalante LLP underlie
warrants we issued to them in September 1999 and September 2000. We issued the
warrants to Gallagher, Harnett & Lagalante LLP as partial payment for legal
services they performed for us related to certain commercial litigation matters.
The September 1999 warrant is for 15,000 shares, has an exercise price of $12.43
per share and has a five-year term. The September 2000 warrant is for 45,000
shares, has an exercise price of $8.00 per share and has a five-year term.
Gallagher, Harnett & Lagalante has served as one of our primary litigation firms
since 1999.

         The shares offered by Keir Kleinknecht, Sabrina Kleinknecht and Gavin
Kleinknecht underlie warrants we issued to Keir Kleinknecht in December 2000. We
issued the warrants pursuant to a consulting agreement with Mr. Kleinknecht
pursuant to which he is and has provided a variety of services to us, including
(1) the recruitment of Mr. DuBois as our chief executive officer, (2) the
recruitment of other senior employees, (3) advice regarding the structure,
timing and amount of financing as we progress with re-establishing our business
and (4) general business advice. The warrants we initially issued to Mr.
Kleinknecht are for a total of 500,000 shares, had an exercise price of $0.70
per share and had a five-year term. The consulting agreement has a one-year
term, and pursuant to the agreement we issued the 500,000 warrants to Mr.
Kleinknecht and agreed to pay him $15,000 per month during the term of the
agreement. The consulting agreement superceded a prior consulting agreement
dated August 2000 pursuant to which we granted Mr. Kleinknecht options to
purchase 25,000 shares at a purchase price of $6.25 per share and agreed to pay
to him $10,000 per month during the one-year  term of the  Agreement.  During
2000, Mr. Klienknecht was also a member of our business advisory board. As a
member of the



                                       19


business advisory board, Mr. Klienknecht was issued options to acquire 20,000
shares at prices ranging from $26.00 to $3.75 per share.

agreement with us. Mr. Francesco was our chief executive officer from March 1999
until November 2000, and he was employed by us at the time we acquired OpenROUTE
Networks, Inc. The acquisition of OpenROUTE constituted a 'change of control'
under Mr. Francesco's employment agreement and, as a result, he became entitled
to 1,000,000 shares of our common stock pursuant to the agreement.

        The shares offered by Bryan Holley were issued to him in full
satisfaction of our indemnification obligations to him through April 21, 2001.

served us as an executive officer from December 1999 until January 2000. In his
capacity as a former executive officer, Mr. Holley is entitled to
indemnification from us with respect to his being named as a defendant in a
class action lawsuit. We owed Mr. Holley approximately $8,000 in indemnification
payments through April 21, 2001, and he agreed to accept payment in shares
valued at the last reported share price on the date of our agreement. That share
price was $1.05 per share.

                   UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                               FINANCIAL STATEMENT

         The following Unaudited Pro Forma Condensed Consolidated Statement of
Operations of Nx Networks for the year ended December 31, 2000 illustrates the
effect of the merger with AetherWorks. The Unaudited Pro Forma Condensed
Consolidated Statement of Operations assumes that the merger with AetherWorks
was completed as of the beginning of the period presented. Certain
reclassifications have been made to the AetherWorks' financial statements to
conform with Nx Networks presentation.

         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 AetherWorks merger as a purchase transaction.
For accounting purposes, Nx Networks is deemed to be the acquiring company in
this merger.

         The pro forma adjustments are based upon currently available
information and assumptions that Nx Networks management believes are reasonable
as well as certain information provided by 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 Statement 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 Statement.

         The Unaudited Pro Forma Condensed Consolidated Financial Statement is
not necessarily indicative of either future results of operations or results
that might have been achieved if the merger with AetherWorks had been
consummated as of the indicated date. The Unaudited Pro Forma Condensed
Consolidated Financial Statement should be read in conjunction with the
historical financial statements of Nx Networks 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 YEAR ENDED DECEMBER 31, 2000

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

(2)  Information obtained from the historical unaudited 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
     acquisition.

(5)  The average common shares outstanding used in calculating basic and diluted
     pro forma loss per common share are calculated assuming that the estimated
     number of shares of Nx Networks common stock issued in the merger was
     outstanding from the beginning of the periods presented. For purposes of
     this Unaudited Pro forma Financial Information, the Company assumed that it
     would issue approximately 7,400,000 shares of common stock (including the
     4,777,793 of additional shares issued in connection with the $22.50 per
     share guarantee negotiated in December 2000) in connection with the
     AetherWorks acquisition. Options and warrants to purchase shares of common
     stock were not included in computing pro forma diluted earnings per common
     share because their inclusion would result in a smaller loss per common
     share.


                              PLAN OF DISTRIBUTION

        The selling stockholders, or their pledgees, donees, transferees or
other successors in interest, may sell up to 16,206,469 shares of common stock
from time to time. No selling security holder is required to offer or sell any
of the 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 market 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 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.

         The selling security holders and any other persons participating in the
distribution of the shares of common stock offered by the selling security
holders will be subject to Securities Exchange Act, which may limit their timing
of purchases and sales of common stock and restrict their ability to engage in
market-making activities.

         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




                                       24




receive proceeds from the exercise of the warrants, and these proceeds will be
approximately $2.2 million 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
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 with 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



                                      II-1


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.
                  (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



                                      II-6


                  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-7
