                                     SUMMARY

NETRIX - NOW CALLED 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.

      Reflecting our new identity resulting from our merger with OpenRoute
Networks, Inc. in December 1999, we are in the process of changing the name of
our company from Netrix Corporation to Nx Networks, Inc.

      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 20717, and our telephone number is
(703) 742-6000.

RECENT DEVELOPMENTS

ACQUISITION OF OPENROUTE

      On December 22, 1999 we completed the acquisition of OpenRoute Networks.
In the transaction, we issued one share of our common stock for each share of
OpenRoute common stock. This resulted in our issuing 15,805,797 shares of common
stock to the former OpenRoute stockholders.

      OpenRoute has distinguished itself as a pioneer in the data communications
industry and as a leader in networking and in networking connectivity solutions
that focus exclusively on the Internet's edge. OpenRoute provides network
connectivity products and solutions that are designed to meet the needs of
Internet service providers and corporate enterprises. OpenRoute's data
networking products and services combine cost effectiveness with ease of
operation, interoperability, network security, reliability and performance.
OpenRoute provides solutions that complement and optimize the edge of a
business' network-at the point at which the business connects to its telephone
company or Internet service provider. OpenRoute is committed to providing
solutions that make the Internet a more cost-effective, secure and comfortable
place to grow a business. Its customers include Global 1000 multinational
corporations, ISPs and other enterprises looking to the Internet to grow their
businesses. Historically, OpenRoute's local area networking products have
provided connectivity solutions in more than 70% of the Fortune 100 companies.

AGREEMENT TO ACQUIRE AETHERWORKS

      On December 31, 1999 we entered into an agreement to acquire AetherWorks
Corporation. The acquisition will be effected, upon closing, through the merger
of AetherWorks with and into Nx1 Acquisition Corp., a wholly-owned subsidiary of
ours.

      AetherWorks provides innovative voice and data carrier class convergence
solutions for the telecommunications industry, including soft switch technology.
AetherWorks focuses on the multi-protocol telecom switch featuring smart
management, universal messaging and other telephony functions. We believe the
combination of AetherWorks and our technologies will serve the converged markets
and allow secure and seamless end-to-end interoperability while providing
advanced voice services. In particular, the combination of AetherWorks and our
technology enables telcos, internet service providers (ISPs), and enterprise
wide area networks and local area networks (WAN/LANs) to provide a secure
end-to-end solution that simplifies networking setups and expands services.

      The transaction was approved by the boards of directors of the three
companies and by the stockholders of Nx1 Acquisition Corp. The holders of over
90% of AetherWorks' common stock have consented in writing to the merger and the
remaining stockholders are expected to deliver their written consent in the near
future. Holders of a majority of the AetherWorks common stock have granted
proxies to us to vote their shares in favor of the merger if a stockholders
meeting is required in lieu of a unanimous written consent.

      Under the terms of the Agreement and Plan of Merger, we will issue
approximately 3.49 million shares of common stock in the acquisition. This total
number of shares includes the number of shares necessary to satisfy AetherWorks
obligations to its option holders and warrant holders. The total number of
shares we will issue is also subject to reduction to reflect the cost of
satisfying an existing $8 million obligation of AetherWorks, and so the exact
number of shares to be issued will be determined at the closing. The total
number of shares will then be apportioned among the holders of AetherWorks
common stock (including for this purpose options and warrants to acquire common
stock) and Class B common stock in accordance with AetherWorks' charter
documents. Each holder of an option or warrant to acquire AetherWorks common
stock will become entitled to acquire the number of shares of our common stock
into which the shares of AetherWorks originally provided in such option or
warrant are converted in the merger.

      Under the terms of the Merger Agreement, a further adjustment will be made
to the merger consideration if the closing price of our common stock on the
Nasdaq Stock Market for the 15 trading day period ended October 31, 2000 does
not equal or exceed $22.50 per share. In such event, additional shares of our
common stock will be issued such that the consideration per share of AetherWorks
common stock is equal to $22.50 per share based upon that average closing price;
provided the total number of shares of our common stock issued in the merger
will not exceed 19.9% of the total of our then outstanding shares.

      We will also issue to AetherWorks' employees options to acquire a total of
1.0 million shares of our common stock. The options will be issued at the
closing, have an exercise price of $6.81 per share and vest over a two to three
year period after the closing of the acquisition.

      The closing of the merger is conditioned upon satisfaction of certain
conditions, including satisfaction of certain outstanding debt obligations of
AetherWorks and finalizing the approval of the merger by AetherWorks'
stockholders.

                                  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, 1998 and 1997, respectively, we incurred
net losses of approximately $6.3 million and $8.6 million and, on a pro forma
basis, after giving effect to the mergers with OpenRoute and AetherWorks, we
would have had a net loss of $64.7 million for the year ended December 31, 1998.
Through September 30, 1999, we have incurred additional losses of approximately
$5.9 million and, on a pro forma basis, after giving effect to the mergers with
OpenRoute and AetherWorks, we would have had a net loss of $45.4 million in this
period. These losses present a significant risk to our stockholders. We expect
to recognize efficiencies in the future and to benefit from better marketing
opportunities and product offerings as a result of the mergers, however, we
cannot assure you that after the mergers we will achieve or sustain
profitability or positive cash flows from operating activities. If we cannot
achieve profitability or positive cash flows from operating activities, we may
be unable to meet our working capital and future debt service requirements,
which would have a material adverse effect on our business, financial condition

                                       4

<PAGE>

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 MAY REQUIRE ADDITIONAL CAPITAL TO FULLY IMPLEMENT OUR BUSINESS PLAN, 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. As described in the preceding
paragraph, there can be no assurance that we will be able to obtain these
necessary funds from our own operations. If we are required to seek third party
financing, 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 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.

OUR CASH FLOW MAY NOT BE SUFFICIENT TO PERMIT REPAYMENT OF OUR INDEBTEDNESS
WHEN DUE

      Our ability to make payments on and to refinance our indebtedness will
depend on our ability to generate cash in the future. There can be no assurance
that our business will generate sufficient cash flow from operations to meet our
debt service requirements. Our cash flow from operations may be insufficient to
repay our indebtedness at scheduled maturity and some or all of such
indebtedness may have to be refinanced. If we are unable to refinance our debt
or if additional financing is not available on acceptable terms, we could be
forced to dispose of assets under circumstances that might not be favorable to
realizing the highest price for the assets or to default on its obligations with
respect to our indebtedness, either of which could have a material adverse
effect on the price of our common stock.

WE MAY ENCOUNTER DIFFICULTIES IN COMBINING OPERATIONS WITH OPENROUTE AND
AETHERWORKS AND REALIZING SYNERGIES FROM THE MERGERS

    We merged with OpenRoute and we have entered into the merger agreement with
AetherWorks with the expectation that the mergers will result in certain
benefits including operating efficiencies, cost savings, synergies and other
benefits. Achieving the benefits of the mergers will depend in part upon the
integration of our businesses with OpenRoute and AetherWorks in an efficient
manner, which we believe will require considerable effort. In addition, the
consolidation of operations will require substantial attention from management.
The diversion of management attention and any difficulties encountered in the
transition and integration process could have a material adverse effect on the
combined company. We cannot assure you that we will succeed in integrating our
operations with those of OpenRoute and AetherWorks in a timely manner or that
the expected efficiencies, cost savings and synergies of the mergers will be
realized.

FAILURE TO COMPLETE, OR DELAYS IN COMPLETING, THE AETHERWORKS MERGER COULD HURT
OUR STOCK PRICE AND FUTURE OPERATIONS

      If the AetherWorks merger is not completed for any reason, the price of
our common stock may decline to the extent that the current market price of the
companies' common stock reflects a market assumption that the merger will be
completed.

                                       5

<PAGE>

      In addition, current and prospective employees of Netrix and AetherWorks
may experience uncertainty about their future role with the companies until
after the merger is completed or if the merger is not completed. This may
adversely affect our ability to attract and retain key management, sales,
marketing and technical personnel.

WE WILL INCUR SIGNIFICANT MERGER-RELATED CHARGES

      We estimate that, as a result of the mergers, we will incur integration
costs associated with:

        o  consolidating corporate headquarters and other administrative
           functions;

        o  terminating certain leases and severance and facility closing costs
           associated with consolidating certain product lines; and

        o  merger-related costs such as financial advisory, legal and accounting
           fees and financial printing and other related charges.

OUR ABILITY TO USE OUR AND OPENROUTE AND AETHERWORKS' NET OPERATING LOSS
CARRYFORWARDS MAY BE LIMITED

      As of December 31, 1998, we had federal income tax net operating loss
carryforwards of $38.1 million which begin to expire in 2002. The ability to use
our net operating loss carryforwards to reduce our future tax payments would be
limited if, within three years of incurring such loss, an ownership change of
more than 50% were to occur. As a result of the OpenRoute merger, our net
operating loss carryforwards from before the date of the merger are subject to
this limitation. In addition, as of December 31, 1998, OpenRoute had federal
income tax net operating loss carryforwards of approximately $33.0 million that
begin to expire in 2010. The extent to which we may use OpenRoute's net
operating loss carryforwards to reduce our future tax liability may be limited.
In addition, as of September 30, 1998, AetherWork's had federal income tax net
operating loss carryforwards of approximately $18.5 million that begin to expire
in 2010. A tax asset related to this loss carryforward does not appear on
AetherWorks' balance sheet because it is unclear if AetherWorks will generate
taxable income prior to the expiration of the net operating loss carryforwards.
The extent to which we may use AetherWorks' net operating loss carryforwards to
reduce our future tax liability may be limited. As a result of these
limitations, our future tax liability may be greater than the combined tax
liabilities of Netrix, OpenRoute and AetherWorks in the absence of the mergers.

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 Netrix 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.

                                       6

<PAGE>

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.

OUR BUSINESS WILL SUFFER IF WE LOSE CERTAIN KEY PERSONNEL OR FAIL TO ATTRACT AND
RETAIN OTHER QUALIFIED PERSONNEL

      The success of our business will be dependent, to a significant extent,
upon the abilities and continued efforts of our management, marketing,
engineering and technical 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, marketing, technical and sales 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 Netrix resulting from the
OpenRoute and AetherWorks mergers, 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 Netrix 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.

THE MARKET PRICE OF OUR COMMON STOCK IS VOLATILE

      The market price of the Netrix common stock has been and can be expected
to be significantly affected by factors such as:

                                       7

<PAGE>

        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.

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 Netrix 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 and AetherWorks have focused our products on the edge of the Internet
and telephony. The markets for products in 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 effected.

      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.

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 53%, 62% and 63% of our total revenues
in 1998, 1997 and 1996, respectively, and international sales will continue to
be significant to us after the mergers with OpenROUTE and AetherWorks. 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.

PURCHASERS OF COMMON STOCK FROM US WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL
DILUTION OF THE BOOK VALUE OF THE INVESTMENT

      We expect that the price at which we sell the common stock in this
offering will be substantially higher than the net tangible book value per share
of our outstanding common stock. Our net tangible book value per share as of
September 30, 1999 was $.70 per share, taking into account the pro forma
adjustments for the OpenROUTE and AetherWorks transactions. As a result, you
will incur immediate, substantiate dilution if you purchase the shares from us.
For example, if we sold all 1.0 million shares of common stock in this offering
for $22.50 per share as of September 30, 1999, then our net tangible book value
per share after the sale transaction would have been $1.13 as a result of
receiving the net cash proceeds. In this event, the buyer would experience
dilution of $21.37 per share, resenting the difference between the purchase
price and the net tangible book value per share after the offering.

                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 estimate that we will receive approximately $21.6 million in net
proceeds from the sale of the stock. This estimate assumes a sales price per
share of $22.50, a 3.5% sales commission and expenses payable by us of $50,000
in connection with the offering. Since we will sell the shares at prevailing
market prices, we may receive greater or less net proceeds than we expect.

      We will use $8 million of the net proceeds to pay an $8 million promissory
note issued by AetherWorks to Digi International Inc. The note does not bear
interest, and it is scheduled to mature in May 2001. The maturity date, however,
will accelerate upon a change of control of AetherWorks. Accordingly, the note
will become due on the date we close the acquisition of AetherWorks, and
satisfaction of the note is a condition to closing the AetherWorks acquisition.
We have agreed that we will sell shares of our common stock to fund repayment of
the Digi International note, and the number of shares we issue to AetherWorks
security holders in the merger will be reduced by the number of shares we sell
for this purpose. We will use the remainder of the net proceeds for general
corporate and working capital purposes. Pending application of the net proceeds,
we will place the net proceeds in short term, interest bearing securities.

      We will not receive any proceeds from the sale of common stock by the
selling security holders. The shares which Kaufman Bros. may sell are currently
represented by a warrant we issued to Kaufman Bros. In order to obtain the
common stock for sale, Kaufman Bros. must exercise the warrant. The warrant has
an exercise price of $3.00 per share, so Kaufman Bros. will pay us $300,000 if
it exercises its warrant in full. We will use the proceeds from this warrant
exercise for general corporate and working capital purposes.

     NETRIX UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

      The following Unaudited Pro Forma Condensed Consolidated Balance Sheet of
Netrix as of September 30, 1999 and the Unaudited Pro Forma Condensed
Consolidated Statement of Operations of Netrix for the nine months ended
September 30, 1999 and the year ended December 31, 1998 illustrate the effect of
the mergers with OpenRoute and AetherWorks. The Unaudited Pro Forma Condensed
Consolidated Balance Sheet assumes that the mergers with OpenRoute and
AetherWorks had been completed as of September 30, 1999 and 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 fiscal
year presented, January 1, 1998. Certain reclassifications have been made to
OpenRoute's and AetherWorks' financial statements to conform with Netrix's
presentation.

      Under the terms of the OpenRoute transaction, the holders of OpenRoute
common stock and stock options received one share of Netrix 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 will receive an aggregate of 1.36 shares of Netrix Common Stock. This
conversion ratio is subject to adjustment based upon the number of Netrix shares
required to satisfy an existing $8,000,000 obligation of AetherWorks, which must
be redeemed upon closing of the proposed merger. The Pro Forma Condensed
Consolidated Financial Statements reflect the use of the $8,000,000 of proceeds
to redeem the note payable.

      ACCOUNTING TREATMENT

      Netrix recorded the OpenRoute merger as a purchase transaction, and it
will record the AetherWorks merger as a purchase transaction. For accounting
purposes, Netrix is deemed to be the acquiring corporation in each merger.

      The pro forma adjustments are based upon currently available information
and assumptions that Netrix management believes are reasonable and certain
information provided by OpenRoute management and AetherWorks management. Netrix
will account 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 preliminary determination of
these adjustments based upon available information. Netrix cannot assure you
that the actual adjustments will not differ significantly from the pro forma
adjustments reflected in the Unaudited Pro Forma Condensed Consolidated
Financial Statements.

      For illustrative purposes, Netrix has made a preliminary allocation of
excess cost over estimated net assets acquired to goodwill as OpenROUTE's assets
and liabilities are estimated to approximate fair value. 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
OpenROUTE at the closing date, Netrix will undertake a study to determine the
fair values of assets and liabilities acquired and will allocate the purchase
price accordingly. Netrix 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,
goodwill and other identifiable intangibles. However, there can be no assurance
that the actual allocation will not differ significantly from the pro forma
allocation.

      For illustrative purposes, Netrix 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, Netrix assumed the price per share to be
$22.50, as guaranteed in the merger agreement. Netrix has also engaged an
independent third party to determine the amount, if any, of the excess purchase
price related to purchased in-process research and development. To the extent
that a portion of the purchase price of AetherWorks is allocated to purchased

                                       14

in-process research and development, the other intangibles would be reduced for
this amount. For every $1.0 million change in the amount allocated to purchased
in-process research and development, annual amortization expense reflected in
the pro forma consolidated statement of operations would decrease by $250,000.
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, Netrix will undertake
a study to determine the fair values of assets and liabilities acquired and will
allocate the purchase price accordingly. Netrix 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 Netrix, OpenRoute and AetherWorks, together
with the related notes thereto, which are incorporated by reference into this
registration statement.

(1)   Information obtained from the historical unaudited condensed consolidated
      statement of operations of Netrix.

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

(3)   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.

(4)   Information obtained from the historical consolidated statement of
      operations of Netrix.

(5)   Information obtained from the historical statement of operations of
      OpenROUTE.

(6)   Information obtained from the historical statement of operations of
      AetherWorks for its year ended September 30, 1998.

(7)   Reflects the amortization expense of the excess of cost over historical
      net assets acquired in the merger by use of the straight-line method over
      4 years.

(8)   Reflects the amortization of $15.7 million of compensation expense for the
      assumed intrinsic value of stock options to be granted to AetherWorks'
      employees immediately subsequent to closing to acquire 1,000,000 shares of
      Netrix common stock at an exercise price of $6.81 per share. The
      compensation expense will be recognized over the options vesting period,
      generally two to three years.

(9)   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 Netrix common stock to be issued in the
      mergers were outstanding from the beginning of the periods presented. For
      purposes of this Pro Forma Financial Information, the Company assumed that
      it would issue approximately 15,900,000 and 2,632,000 million shares of
      common stock in connection with the OpenROUTE acquisition and the
      AetherWorks acquisition, respectively. 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.

                                    BUSINESS

      Netrix, now called Nx Networks, is a worldwide provider of internet
telephony and data networking solutions. We deliver a high performance, scalable
product suite that serves today's voice and data convergence needs while
anticipating tomorrow's demands for secure packet and cell based telephony
solutions. We combine patented, switched, compressed voice and data technology
with advanced packet data networking capabilities to provide networking
solutions that improve network performance and deliver an array of tangible
network services.

      We have distinguished ourselves as a pioneer in the data communications
industry and as a leader in voice, data networking and networking connectivity.
Currently, we are pioneering next generation softswitch and intelligent service
technologies that will simplify networking setups and service offerings and
provide a platform for application services. Our customers include service
providers, multinational corporations and government agencies in over 60
countries.

      CORPORATE OBJECTIVES

      Our goal is to be a leading provider of internet telephony solutions. We
recognize that internet telephony is driving the communications industry to
achieve an intelligent, feature rich and all-encompassing network. We intend to
deliver solutions that offer secure, seamless end-to-end interoperability and
voice services to this market.

      Our acquisition of AetherWorks provides us with superior softswitch
technology and the resources to significantly expand our penetration of the
rapidly growing internet telephony services market. Specifically, we believe
this technology allows us to bring differentiated services to customers faster
than our competitors. We will capitalize on our services segment by introducing
innovative new products.

      We believe that our product developments enhance the growth of the
deployment of multi-service networks, the adoption of virtual private networking
(VPNs) and the implementation voice over virtual private networking (VoVPN). Our
tactical developments also reflect service provider deregulation and
competition, the growth of e-commerce and the increased demand for comprehensive
internet protocol services.

      During 2000, we plan to deliver the following solutions to service
providers, corporations and carriers in the market segments indicated:

        o  VIRTUAL PRIVATE NETWORKING -Nx Networks GT and GTX Series is an award
           winning full-featured VPN edge router products.

        o  VOICE OVER VIRTUAL PRIVATE NETWORKING (VOVPN) - Nx Networks 3000
           Series combines voice and data within a VPN.

        o  CARRIER CLASS VoIP GATEWAY - The upcoming Nx Networks 4000 Series
           delivers carrier class voice over IP gateways that are standards
           based and scalable.

        o  CARRIER GRADE SOFTSWITCH TECHNOLOGY - Our superior softswitch
           technology runs on virtually all Unix platforms and is easily
           enhanced. This technology will debut in the Nx Networks 6000 Series,
           presently under development.

        o  CUSTOMER PREMISE EQUIPMENT - We offer a complete series of edge
           products - both voice and data - with full feature sets and robust
           quality.


      BACKGROUND

      The coming together of internet standards, voice over internet protocol
(VOIP) and virtual private networking (VPN) makes the combining of voice and
data, long treated as separate technologies, a sound business decision. As
network infrastructures converge and consolidate, fewer networks and protocols
support an increasing number of applications. The internet protocol (IP) for the
local area network (LAN), along with frame relay and asynchronous transfer mode
(ATM) for wide area networks (WAN) are the leading technologies in this market
space, displacing previous technologies.

      These technological trends, combined with the proliferation of global
trade, have created a growing reliance on secure converged telecommunications to
facilitate commerce. In an environment where wide area networking is critical to
daily operations, secure voice and data communications over different network
media types represent a significant and increasing component of operating costs
for enterprises. We have focused our new products to support needs of this new
network model.

      The varying traffic characteristics of different types of networking
applications, together with the need to transmit voice and image as well as
data, has created the need for vendors to supply multi-service platforms to meet
the user requirements within a single network fabric. Technologies in use today
include IP, frame relay, integrated services digital network (ISDN), and ATM.
Multi-service platforms, such as Nx Network Exchange products, enable our
customers to support multiple applications across a single network, thereby
resulting in improved connectivity, generally reduced communications costs, and
improved network performance.

      The increasing availability of IP and frame relay services on the public
networks has fueled a trend toward building corporate networks that access these
services on an as-needed basis. Our products can be used to implement voice and
data networks based upon private lines, public services, or a combination of
private and public services. We believe that the trend toward the use of
services will continue to grow, especially with global telecommunications
deregulation. The use of the internet will also expand voice and fax
applications.

      In November, 1999, we launched a comprehensive equipment leasing solution
through a strategic partnership with First Venture Leasing Corporation. This
leasing solution allows us to offer emerging and established carriers the
financial tools needed to build a complete internet telephony infrastructure
using our equipment without traditional large up-front capital expenditures.

      In December, 1999, we introduced the 3000 Series, which delivers a secure
solution for converged internet telephony and data. The 3000 Series combines
high-quality IP voice and routing into a single end-to-end solution for secure
voice and data communications.

      The 3000 Series positions us firmly in the VoIP and VPN telephony market
space, which is emerging as the next wave of network consolidation and which
leverages the vast worldwide IP infrastructures being deployed. It also
positions us for the emerging service provider space by enabling them to offer
low cost telephony solutions while realizing a short-term return on the
equipment investment.

      We believe that secure internet telephony, in particular, represents a
short-term opportunity to gain substantial service provider market share. We
believe that our current product offering provides several advantages over
existing competing products in the areas of performance, security, scalability,

                                       22

flexibility, cost, channel capacity and bandwidth efficiency. We have recently
been able to offer carrier quality voice over packet solutions to service
providers over wide area networks at significant reductions in per minute
operating costs. Particularly with regard to bandwidth allocation, our
capability to bundle multiple voice samples from different calls in a single
packet allows improved bandwidth management over long distances. We believe we
are positioned to be among the leaders in IP voice/data wide area networking
equipment in 2000.

      With the introduction and continued development of the Series 3000, we are
moving toward the ability to deliver secure voice and data integration over
almost any carrier infrastructure, with the goal of making the products as easy
to configure and provision as possible. In addition our products' ability to
shape traffic and prioritize applications and to customize bandwidth utilization
on demand to suit end users needs, make the 3000 Series an ideal platform for
service providers looking to deliver next generation services in order to
differentiate themselves. Whether provisioning service or selling customer
premise equipment (CPE) to end users, the range of products will be well
positioned for the service provider market.

      On December 31, 1999 we entered into an agreement to acquire AetherWorks
Corporation, a provider of innovative softswitch technology for the
telecommunications industry. We believe that the addition of AetherWorks'
technology provides us with a distinct competitive advantage in developing
solutions our customers need to succeed in the internet telephony arena.
Specifically, AetherWorks provides the technology which will enable an
intelligent, feature-rich and all encompassing network to emerge. In addition,
this acquisition moves us from the customer premise "edge" to the telco and
carrier "edge". We believe the combination of our and AetherWorks' technologies
will serve a growing converged market and allow secure, seamless end-to-end
interoperability while providing feature rich services at a significant cost
savings.

      MARKETING AND SALES

      Our customers include service providers, multi-national corporations and
government agencies in over 60 countries. To address these markets throughout
the world, we have established a multi-channel distribution and sales network.
Our products are designed to provide enterprise voice/data solutions and are
marketed mostly through indirect channels, either via carriers or enterprise
focused partners worldwide. We also have a direct sales force who sell directly
to large corporations worldwide. Service providers resell our products as part
of their service offerings as well. Marketing programs to support all these
channels center around advertising, direct lead generation programs and industry
analyst cultivation.

      Our breadth of voice and data products, now enhanced by the acquisition of
AetherWorks softswitch technology, has strengthened our position as a leading
worldwide provider of internet telephony and data networking solutions.
Specifically, our strategy to move from the customer edge to the carrier edge is
now firmly in place, with product development underway. In addition, the Nx
Networks 3000 Series has combined voice and data security technologies and is
positioned to capture the convergence of these markets. In addition, our leasing
program is effectively expanding our reach into many more opportunities.

      CUSTOMER SUPPORT AND SERVICE

      A significant element of our strategy has been to provide service, repair,
and technical support for its customers throughout the world. A substantial
portion of our service and support activity relates to software and network
configuration and is provided by 24-hour per day, 7 days per week telephone
support through the Nx Networks Technical Assistance Center ("TAC"). Our
products are designed to allow the TAC to be on line with any Nx Networks
network in the world to diagnose problems and to respond with solutions. In


                                       25
<PAGE>

addition, our hardware is designed to facilitate replacement of failed boards;
in many cases, the customer's personnel can replace a board themselves under the
direction of the TAC. TAC service is provided directly to end users and as a
backup service to our international distributors.

      Our personnel and third party providers perform most domestic hardware
maintenance and installation. For customers outside the United States, these
services are generally provided by our international Value Added Resellers
(VARs). We typically offer our customers a hardware warranty ranging from 90
days to one year and offers an optional annually renewable hardware maintenance
and software support contract with the network.

      With the acquisition of OpenRoute line of VPN/Data routers, we added a
line of routers that are easily locally/remotely managed. Because of the
strength of product engineering, we offer a lifetime warranty on these units.

      We offer support contracts to our customers with optional levels of
support, with each option being priced accordingly. In addition, we provide
technical consulting and training both to end-users and to distributors. Many of
our customers currently have support and maintenance contracts with us. Customer
service as a percent of revenue was 31% in 1998, 32% in 1997 and 26% in 1996.

      RESEARCH AND DEVELOPMENT

      We believe our future success depends on our ability to continue to
enhance our products to improve performance and functionality and to develop new
products that address emerging networking market niches. Research and
development as a percent of revenue was 22% in 1998, and 25% in 1997 and 1996.

      MANUFACTURING

      Our manufacturing operations are a combination of system level
integration and testing and full turnkey.  We have strategic relationships
with The SMT Centre of Charlotte, North Carolina (SMTC), U.S. Assemblies of
Taunton, Massachusetts (U.S. Assemblies) and Venture Manufacturing Ltd. Of
Singapore (Venture).

      Effective October 1, 1999, we entered into an agreement with SMTC to
outsource all manufacturing and test operations for current products. SMTC is a
contract manufacturer that offers a cost-effective, high volume, manufacturing,
distribution and repair capabilities worldwide. Historically SMTC has produced
various sub-assemblies for us, but the new agreement calls for them to
manufacture, test and ship final products. Our employees associated with
manufacturing, distribution and repair operations were transferred to SMTC
effective October 1, 1999.

      U.S. Assemblies and Venture manufacture our board assemblies for certain
router products and provide turnkey manufacturing for certain other router
products. SMTC provides full turnkey manufacturing for our voice products. We
believe that in the event of an interruption in manufacturing at any of our
subcontractors, we will be able to shift our production needs to an unaffected
facility and continue to meet expected demand. Each of our subcontractors
operate a number of other plants in the United States and Asia.

      We perform some final assembly and testing of routers at our Westborough
facility. A repair depot is also located at the Westborough facility,
coordinating service requirements for our router products.

      COMPETITION

      We encounter substantial competition in the marketing of our products, and
many of our competitors have greater financial, marketing and technical
resources. Important competitive factors in our product markets are established
customer base, product performance and features, service and support, as well as
price. We believe that we compete favorably with respect to these factors. There
can be no assurance that our products will compete successfully with competitive
products that may be offered in the future or that aggressive pricing will not
adversely impact our profitability.

      PROPRIETARY RIGHTS

      We rely on a combination of patents, trade secret, copyright and trademark
law, non-disclosure agreements, and technical measures to establish and protect
our proprietary rights in our products. Despite these precautions, it may be
possible for unauthorized third parties to copy aspects of our products or to
obtain and use information that we regard as proprietary. The laws of some
foreign countries in which we sell or may sell our products do not protect our
proprietary rights to the same extent as do the laws of the United States.

      We believe that because of the rapid pace of technological change in the
networking industry, patent and copyright protection, while important, are less
significant to our competitive position than factors such as the knowledge,
ability, and experience of our personnel, new product development, market
recognition, and ongoing product maintenance and support. We believe that our
products and trademarks do not infringe upon the proprietary rights of third
parties. There can be no assurance, however, that third parties will not assert
infringement claims in the future.

      To protect our intellectual property rights in the "voice over" market
space, the prime patents held by us in packetized compressed voice networking
have been brought to the attention of both the voice over internet protocol and
frame relay forum organizations.

      We also use various licensed products of other companies in certain of our
products.

      EMPLOYEES

      We had 190 employees at December 31, 1999. None of the employees are
represented by collective bargaining agreements. We have never experienced any
work stoppage. We believe that our employee relations are satisfactory.

      PROPERTIES

      Our principal administrative and research and development facilities
consist of approximately 45,000 square feet located in Herndon, Virginia and
approximately 44,000 square feet in Westborough, Massachusetts. The Herndon
premises are occupied under a lease agreement that was negotiated for a ten-year
term expiring April 30, 2009. The Westborough premises are occupied under a
lease expiring in April 2002. In connection with cost savings initiatives we
undertook in 1999, we subleased approximately 22,000 square feet of the Herndon
facility, thereby reducing rent expense by approximately $50,000 per month. A
separate facility of 8,600 square feet is under lease in Longmont, Colorado for
product development operations. Additionally, we maintain six sales and support
offices in the United States and abroad. We believe our facilities are adequate
for our current needs.

      LITIGATION

      We are periodically a party to disputes arising from normal business
activities. In the opinion of our management, 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.

                              PLAN OF DISTRIBUTION

SALES BY NX NETWORKS

      We will sell the 1,000,000 shares offered by us through Kaufman Bros.
L.P. and/or Tucker Anthony, Incorporated, from time to time in a series of
"at the market" transactions effected on the Nasdaq Stock Market.  In
offering the shares, Kaufman Bros. and Tucker Anthony will act as our agents
and use their reasonable best efforts to find buyers for the shares.  Kaufman
Bros. and Tucker Anthony, Inc. are not obligated to purchase any of the
shares for their own account and we are not obligated to sell all of the
1,000,000 shares.

      Kaufman Bros. and Tucker Anthony do not expect to undertake any special
selling efforts in connection with the distribution of shares on our behalf.
Under the rules of the SEC, however, they are considered underwriters as a
result of their actions as our agents. Accordingly, they will have to comply
with applicable prospectus delivery requirements and Regulation M under the
Securities Exchange Act. Regulation M will preclude Kaufman Bros. and Tucker
Anthony from making a market in our common stock during the offering of our
shares.

      For their services as agents, Kaufman Bros. and Tucker Anthony will be
paid 3.5% of the sales price of the shares they sell. In addition, we will
indemnify Kaufman Bros. and Tucker Anthony for certain liabilities, including
liabilities under the Securities Act of 1933.

      Kaufman Bros. provided financial advisory services to us from May 1999
through December 1999 pursuant to an investment advisory agreement. Pursuant to
the agreement, we issued to Kaufman Bros. warrants to acquire the 100,000 shares
that they are offering hereby. In addition, Kaufman Bros. acted as our financial
advisors in connection our acquisition of OpenRoute. For their services in that
transaction we issued to them 54,500 shares of common stock, which had a value
of approximately $1.0 million on the date of issue. Tucker Anthony acted as the
financial  advisor to OpenRoute in connection with our acquisition of OpenRoute.
For their services in that transaction, OpenRoute issued to them 145,500 shares
of OpenRoute common stock, which converted into an equal number of our shares
when the merger was completed. On the date the merger was completed, those
shares had a value of approximately $2.0 million.

      Kaufman Bros. is also a selling shareholder, and will sell up to
100,000 shares of common stock that it currently owns.  Kaufman Bros. will
not sell any shares for its own account until after it has completed its
distribution activities as our agent.

SALES BY SELLING STOCKHOLDERS

      The common stock may be offered and sold from time to time by one or more
of the selling stock holders, or by pledgees, donees, transferees or other
successors in interest. No selling stock holder is required to offer or sell any
of his common stock. The selling stock holders anticipate that, if and when
offered and sold, the common stock will be offered and sold in transactions
effected on the Nasdaq Stock Market at then prevailing market prices. These
transactions could include block transactions. The selling stock holders reserve
the right, however, to offer and sell the common stock on any other national
securities exchange on which the common stock is or may become listed or in the
over-the-counter market, in each case at then prevailing market prices, or in
privately negotiated transactions each at a price then to be negotiated. All
offers and sales made on the Nasdaq Stock Market or any other national
securities exchange or in the over-the-counter market will be made through or to
licensed brokers and dealers. No agreements, arrangements or understandings have
been entered into with any broker or dealer, and no brokers or dealers have been
selected, in connection with the offer and sale of the common stock. All
proceeds from the sale of the common stock will be paid directly to the selling

                                       32

stock 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 stock holders. However, we will receive proceeds
from the exercise of the warrants by Kaufman Bros. No discounts, commissions or
other compensation will be allowed or paid by the selling stock holders or by us
in connection with the offer and sale of the common stock except that usual and
customary brokers' commissions may be paid by the selling stock holders.

      The selling broker may act as agent or may acquire shares of common stock
or interests in common stock as principal or pledgee and may, from time to time,
effect distributions of shares of common stock or interests. If a dealer is
utilized in the sale of common stock in respect of which the prospectus is
delivered, the selling stock holders will sell common stock to the dealer as
principal. The dealer may then resell the common stock to the public at varying
prices to be determined by the dealer at the time of resale.

      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. The fees and expenses we will pay are estimated to be
$50,000.

                                  LEGAL MATTERS

      The validity of the common stock offered by this prospectus will be passed

                         Report of Independent Auditors


Board of Directors and Shareholders
AetherWorks Corporation

      We have audited the accompanying balance sheets of AetherWorks Corporation
(a development stage company) as of September 30, 1999 and 1998, and the related
statements of operations, shareholders' equity (deficit) and cash flows for the
years then ended and the period from February 24, 1993 (inception) to September
30, 1999. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of AetherWorks Corporation (a
development stage company) at September 30, 1999 and 1998, and the results of
its operations and its cash flows for the years then ended and the period from
February 24, 1993 (inception) to September 30, 1999, in conformity with
generally accepted accounting principles.

      The accompanying financial statements have been prepared assuming the
Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company's deficit accumulated during the development
stage raises substantial doubt about its ability to continue as a going concern.
The Company intends to obtain additional financing to permit it to continue its
operations. The financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

                  NOTES TO AETHERWORKS FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1999

1.    DESCRIPTION OF BUSINESS

      AetherWorks Corporation (the "Company") was formed on February 24, 1993
and is a development stage company engaged in the design and development of
hardware and software which will integrate voice and data. In addition, the
software developed provides a computer telephony framework on which software
applications can operate in the telephony environment.

2.    GOING CONCERN

      As reflected in the accompanying financial statements, the Company has
accumulated a deficit during its development stage. The Company may be unable to
maintain solvency unless it continues to obtain additional financing to continue
as a going concern. The Company intends to obtain additional debt or equity
financing in fiscal 2000 to fund operations.

      Because of uncertainties regarding the achievability of management's
plans, no assurances can be given as to the Company's ability to continue in
existence. The financial statements do not include any adjustments to reflect
the possible future effects on the recoverability and classification of assets
or the amount and classification of liabilities that may result from the
possible inability of the Company to continue as a going concern.

3.    SUMMARY OF ACCOUNTING POLICIES

      CASH AND CASH EQUIVALENTS

      The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. Cash equivalents are
carried at cost which approximates market value.

      PROPERTY AND EQUIPMENT

      Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the estimated useful lives of the assets of three
or five years.

      INCOME TAXES

      Income taxes are accounted for under the liability method. Deferred income
taxes are provided for temporary differences between the financial reporting and
tax bases of assets and liabilities.

      RESEARCH AND DEVELOPMENT

      All research and development costs are charged to operations as incurred.

                                      F-8

      USE OF ESTIMATES

      The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

      STOCK-BASED COMPENSATION

      The Company follows Accounting Principles Board Opinion No. 25, ACCOUNTING
FOR STOCK ISSUED TO EMPLOYEES (APB 25), and related interpretations in
accounting for its stock options. Under APB 25, no compensation expense is
recognized when the exercise price of stock options equals the market price of
the underlying stock on the date of grant.

      IMPAIRMENT OF LONG-LIVED ASSETS

      The Company will record impairment losses on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount.

4.    LONG-TERM DEBT AND CAPITAL LEASE OBLIGATIONS

      Long-term debt, including capital leases, is:

      In October 1995, the Company entered into a 1995 Note Purchase Agreement
("the Agreement") with a data communications company ("Creditor"). Upon the
closing of the Agreement, the Company issued a convertible note for $3,363,235.
The Creditor committed to provide additional funding in the event that certain
milestones were attained, but had no obligation to provide continued funding in
the event two or more milestones were missed.

      In June 1996, the Creditor and the Company restated and amended the 1995
Note Purchase Agreement, principally to eliminate milestones set forth in the
Agreement as well as to obtain additional financing to acquire and develop new
technology and to modify the Creditor's option to convert all, but not less than
all, of the aggregate outstanding principal and interest of the Note into
between 51% and 62.7% of the Common Stock of the Company, depending on the
amount of the Company's borrowings from the Creditor. Upon the closing of the
1996 Restated and Amended Note Purchase Agreement (the "1996 Note Purchase
Agreement"), the Company issued an additional note to the Creditor in the amount
of $1,433,290. The 1996 Note Purchase Agreement also gave the Company the option
to issue additional notes to the Creditor, provided that the aggregate amount of
the additional notes did not exceed $9 million. The Company had issued

                                      F-9

<PAGE>

additional notes for $500,000 as of September 30, 1996. In 1997, the Company
issued additional notes for $6,500,000 which brought the total amount of notes
outstanding at September 30, 1997 to $11,796,525.

      In October 1997, the Creditor and the Company restated and amended the
1996 Note Purchase Agreement, principally to provide the Company the ability to
pay back a portion of convertible notes. Upon the closing of the 1997 Note
Purchase Agreement ("the 1997 Agreement"), the Company exchanged all outstanding
convertible notes for a new convertible note ("Note A") to the Creditor in the
amount of $11,796,525. Under the terms of the 1997 Agreement, the Company
obtained additional advances from the Creditor in the amount of $2,000,000.
Funds advanced to the Company were added to Note A, which incurred interest at
prime plus 3% and was payable in full on December 31, 1998.

      The Company also issued a second non-convertible note ("Note B") under the
1997 Agreement in the amount of $1,802,626 to the Creditor. This amount
consisted of $1,402,895 for all of the outstanding aggregate accrued interest at
September 30, 1997 on the previously outstanding notes, $29,731 for accrued
interest to the date of the 1997 Agreement, and $370,000 as consideration for
certain lease guarantees provided by the Creditor. The outstanding balance of
Note B increased by the amount of interest that accrued on Note A ($120,925
through May 12, 1998). Note B incurred interest at prime plus 3% and was payable
in full (interest and principal) on December 31, 2000.

      In May 1998 (the "1998 Agreement") the Creditor and the Company restated
and amended the 1997 Note Purchase Agreement, principally to rescind all
convertible rights of the Creditor and to release the Creditor from guarantees
on certain lease agreements. Upon the closing of the 1998 Agreement the Company
exchanged Notes A and B for a new non-interest-bearing, non-convertible note
("1998 Note") to the Creditor in the amount of $8,000,000. The 1998 Note is due
and payable on May 12, 2001. The $8,482,590 of debt forgiveness in restructuring
Notes A and B into the 1998 Agreement is recorded as an extraordinary gain in
the statement of operations for the year ended September 30, 1998.

      In connection with the financing agreements, the Company incurred
cumulative financing costs of $805,139, including $370,000 payable to the
Creditor as compensation for their guarantee of certain lease agreements. Under
the 1998 Agreement, the Creditor was released from all guarantees on certain
lease agreements. Since the creditor no longer guaranteed the lease agreements
upon execution of the Securities Purchase Agreement (see Note 5), the deferred
financing costs were written down to zero during the year ended September 30,
1998.

      On November 27, 1996, the Company entered into a promissory note (the
"Note") for $80,000 with the Housing and Redevelopment Authority of the City of
Saint Paul. The Note bears interest at 10.25% per annum and is payable
semi-annually through its maturity date of November 27, 2001. The provisions of
the accompanying loan agreement allow for all or a portion of the Note to be
forgiven based on defined employment levels and for events of default which may
accelerate the due date.

      On September 14, 1999, the Company entered into an unsecured, convertible
note payable (the "Note") with a network and enterprise management software
company (the "Investor" in Note 5) in the amount of up to $1,790,000. Upon the
execution of the Note, the Investor advanced $1,035,147 to the Company. In
October 1999, the Investor advanced the remaining funds to the aggregate amount
of $1,790,000. Under the Note, the outstanding principal and all accrued
interest shall be converted into Series B-1 Common Stock on September 14, 2004
at a conversion price of $37.07 per share.

      The outstanding principal of the Note and all accrued interest can be
converted into Series B-1 Stock at $37.07 per share at any time by the Investor.
The Company has the right to convert the Note and all accrued interest upon the

                                     F-10

<PAGE>

closing of any future equity financing of at least $3,000,000 from an investor
other than the holder of the Note (the "First Financing"), immediately prior to
the closing of a merger, sale or consolidation of the Company which occurs prior
to the First Financing or immediately prior to an initial public offering of the
Company's stock.

      Under the Note, interest is due on the unpaid principal at the rate of 8%
per year and will accrue every six months beginning on March 14, 2000 until the
conversion into Series B-1 Common Stock.

      The carrying amounts of the Company's debt instruments at September 30,
1999 and 1998 approximate fair value except for the 1998 Note whose fair value
is approximately $6,365,000 and $5,443,000, respectively, based on an assumed
interest rate of 15%.

      During fiscal 1996 and 1997, the Company entered into several long-term
lease agreements covering certain equipment, computer hardware and computer
software which are classified as capital leases.

      Leased assets included in the accompanying balance sheet as of September
30, 1999 consist of:

5.    SALE OF SERIES B-1 COMMON STOCK

      On May 12, 1998, the Company entered into a Securities Purchase Agreement
(the "Agreement") with a network and enterprise management software company (the
"Investor"). Under the Agreement, the Investor agreed to purchase an aggregate
of 148,365 shares of Series B-1 Common Stock at $37.07 per share for total
proceeds of $5,500,000 contingent upon the achievement of certain technical


                                     F-11

<PAGE>
milestones. As of September 30, 1999, the Company had issued 148,365 shares
(26,974 shares issued during 1999) of Series B-1 Common Stock at $37.07 per
share for total proceeds of $5,500,000 ($1,000,000 in 1999).

      In connection with the Agreement, the Company granted the Investor a
warrant to purchase 140,789 shares of Series B-2 Common Stock at $37.07 per
share. The warrant is immediately exercisable and expires on May 12, 2008.
Additionally, the Investor agreed to guarantee certain lease obligations
previously guaranteed by the Creditor of the 1998 Agreement (see Note 4). The
Company granted the investor a security interest in all assets of the Company to
secure the guarantee.

      The Series B Common Stock has liquidation preference over other Common
Stock equal to $5,500,000 (assuming all Series B-1 shares are issued). The
liquidation is junior to the $8,000,000 non-interest-bearing note payable under
the 1998 Agreement (See Note 4). The Series B Common Stock is redeemable at the
option of the Investor at any time after May 12, 2005 at $5,500,000 (assuming
all Series B-1 shares are issued) plus the amount paid to exercise the warrants
if the warrants have been exercised. The Series B Common Stock is convertible
into general Common Stock at any time at the option of the Investor and
automatically upon an initial public offering as defined in the Agreement.

      On March 10, 1999, the Company issued 53,952 shares of Series B-1 Common
Stock at $37.07 per share to the Investor for total proceeds of $2,000,000.

      On September 14, 1999, the Company entered into an agreement and release
with Investor, under which the Company issued 49,096 shares of Series B-1 Common
Stock at $37.07 per share or total consideration of $1,820,000. The total
consideration consisted of $1,500,000 of cash and $320,000 of parts used in the
development of the Company's technology and products. Under the agreement, the
Company also agreed to pay the Investor a royalty of .5% of future sales in
excess of $10,000,000 of products utilizing Investor's technology under a
perpetual, non-exclusive license as defined in the agreement.

      Additionally, the Company issued the Investor a warrant to purchase 40,000
shares of the Company's Common Stock at the offering price to the public in an
initial public offering of the Company's stock. The exercise price of the
warrant is the fair market value of the Company's Common Stock on the date of
its initial public offering. If the Company's Common Stock is not traded on an
exchange at the time of exercise, the fair market value is the price established
by the Company's Board of Directors. The warrant expires on September 13, 2004.

6.    OPERATING LEASES

      The Company leases various property and equipment under operating leases
that expire on various dates through fiscal 1999. In 1996, the Company entered
into operating leases for its office facility in St. Paul, Minnesota and its
technical facility in Santa Clara, California, which expire in fiscal 2002 and
1999, respectively. Operating expenses including maintenance, certain utilities
and insurance are paid by the Company. Total rent expense under non-cancelable
operating leases was $498,922 and $512,051 for the years ended September 30,
1999 and 1998, respectively.

                                                   =============

7.    INCOME TAXES

      Upon inception, the Company operated as an S Corporation whereby taxable
income or loss was passed through to the shareholders. The Subchapter S election
was terminated on May 31, 1994 and, as a result, the Company became subject to
federal and state income taxes. Also, as of that date, the Company's accumulated
deficit of $307,754 incurred while the Company was an S Corporation was
reclassified to additional paid-in capital.

      At September 30, 1999, the Company had net operating loss carryforwards of
approximately $18.5 million which are available to offset future taxable income
and begin to expire in the year 2010 and which are subject to limitations if
significant ownership changes occur.

      The net deferred tax assets resulting from net operating loss
carryforwards and other temporary differences are fully offset by a valuation
allowance.

8.    STOCK OPTIONS AND WARRANTS

      The Company has a stock option plan (the 1997 Stock Option Plan) which
provides for the granting up to a total of 600,534 incentive stock options to
employees and nonqualified stock options to employees, directors, and
consultants. Certain incentive stock options granted to employees vest according
to a two-phase schedule. In phase one no options shall vest until the sooner of
the following dates: (1) January 2, 1999, or (2) 90 days after the Company's
initial public offering. Upon the occurrence of the sooner of the dates in phase
one, options shall vest according to optionee's years of service with the
Company, measured retroactively from the date of first employment with the
Company and extending over a subsequent period of no longer than six years,
beginning with 20% vesting on the first anniversary date of employment and
increasing in 20% increments each year thereafter. The incentive stock options
granted during 1999 generally vest 25% each year from the grant date. The
non-qualified stock options granted vest immediately.

      The Company accounts for stock options under APB 25, under which no
compensation cost has been recognized. Had compensation cost for these options
been determined consistent with Statement of Financial Accounting Standards No.
123 (FAS No. 123), ACCOUNTING FOR STOCK-BASED COMPENSATION, the net loss would
have been increased to $8,263,034 compared to $7,916,330 as reported for the
year ended September 30, 1999. The impact of FAS No. 123 was not material for
1998.

      For purposes of calculating the above required disclosure, the fair value
of each option grant is estimated on the date of grant using the minimum value
option pricing model with the following weighted average assumptions used for
grants in 1999, respectively, risk-free interest rates of 5.25%, no expected
dividend yield and expected life of four years.

      The weighted average fair value of options granted during 1999 was $1.31
per share. Options issued which remain outstanding at September 30, 1999, have a
weighted average exercise price of $7.23 per share and had a weighted average
remaining contractual life of 7.5 years.

      For the year ended September 30, 1998, the Company recorded compensation
expense of $48,440 in connection with non-qualified stock options granted to
outside consultants.

      As of September 30, 1999, the Company had outstanding warrants to purchase
a total of 218,153 shares of Common Stock at a weighted average exercise price
of $31.87 per share. The warrants expire at various dates through May 2008.

9.    RELATED PARTY TRANSACTION

      In June 1996, the Company loaned the President and Chief Executive Officer
of the Company $110,000 under a promissory note. The note, including accrued
interest at 7.25% per annum, was due on or before June 10, 2001. During 1999,
the Board of Directors agreed to cancel the promissory note along with the
accrued interest which resulted in a $133,541 expense to the Company. This
amount is shown as a separate line item in the statement of operations for the
year ended September 30, 1999.

10.   BENEFIT PLAN

      The Company has a defined contribution retirement plan covering
substantially all employees under Section 401(k) of the Internal Revenue Code.
The Company recorded an expense of $57,082 and $45,897 for contributions to the
Plan for the years ended September 30, 1999 and 1998, respectively.

11.   YEAR 2000 (UNAUDITED)

      Like other business organizations, the Company could be adversely affected
if the computer systems used by the Company or its customers and suppliers do
not properly process and calculate date-related information and data from and
after January 1, 2000. This is commonly known as the "Year 2000 Issue."
Management is taking steps that it believes are reasonably designed to address
the Year 2000 Issue with respect to computer systems that the Company uses, and
to obtain reasonable assurances that appropriate steps are taken by customers,
suppliers and other major service providers. At this time, however, there can be
no assurance that these steps will be sufficient to avoid any adverse impact to
the Company.

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
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
<PAGE>

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 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,

                                      II-5
<PAGE>

            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.

                                   SIGNATURES

      In accordance with the requirements of the Securities Act of 1933, as
amended, Netrix Corporation certifies that it has reasonable grounds to believe

February 3, 2000

Netrix Corporation
13595 Dulles Technology Drive
Herndon, VA 20171

Ladies and Gentlemen:

      We have acted as special counsel to Netrix Corporation, a Delaware
corporation (the "Company"), in connection with the registration statement on
Form S-3 (No. 333-____) (the "Registration Statement") pertaining to the
proposed offering of 1,200,000 shares of common stock, $.05 par value per share
(the "Shares"), as described in the Registration Statement. The Shares are
issuable by the Company, have been issued by the Company or are issuable upon
the exercise of certain warrants described in the Registration Statement (the
"Warrants"). As such counsel, you have requested our opinion as to the matters
described herein relating to the Shares. All capitalized terms used but not
defined herein shall have the meanings assigned to them in the Registration
Statement.

      We have examined the Company's certificate of incorporation and by-laws,
in each case as amended through the date hereof; the agreement related to the
Warrants (the "Warrant Agreement"); minutes of the Company's corporate
proceedings through the date hereof, as made available to us by officers of the
Company; an executed copy of the Registration Statement, as amended to date, and
all exhibits thereto in the form filed with the Securities and Exchange
Commission; and such matters of law and such documents and other instruments as
we have deemed necessary by us in order to deliver the within opinion. In the
course of our examination, we have assumed the genuineness of all signatures,
the authority of all signatories to sign on behalf of their principals, if any,
the authenticity of all documents submitted to us as original documents and the
conformity to original documents of all documents submitted to us as certified
or photostatic copies. As to certain factual matters, we have relied upon
information furnished to us by officers of the Company.

      Based on the foregoing and solely in reliance thereon, it is our opinion
that the Shares have been duly authorized, and with respect to the shares not
yet issued, when they are issued upon exercise of the Warrants or as
contemplated by the Registration Statement, against payment of the consideration
therefore contemplated by the Warrant Agreement and the Registration Statement,
as the case may be, the Shares will be validly issued, fully paid and
non-assessable.

      We hereby consent to the filing of this letter as an exhibit to the
Registration Statement and to the reference to it in the prospectus included
therein under the caption "Legal Matters."

                                    Very truly yours,

                                    KELLEY DRYE & WARREN LLP

                                By: /s/ Jay R. Schifferli
























                                                                  EXHIBIT 10.22



                            CREDIT FACILITY AGREEMENT
                                       AND
                                 PROMISSORY NOTE


     This CREDIT FACILITY  AGREEMENT (the "Agreement") is made as of February 3,
2000 between Netrix  Corporation  (the  "Borrower") and Steven T. Francesco (the
"Lender").


SECTION 1.  AMOUNT AND TERMS OF THE CREDIT FACILITY

     1.1 THE CREDIT FACILITY

     Subject to the terms and conditions of this Agreement and the Note (as such
term is defined in Section 1.2 below),  the Lender  agrees to make  available to
the Borrower a credit  facility  (the  "Facility")  under which the Borrower may
from time to time on or after the date hereof to and  including  the  Expiration
Date (as such term is defined in Section  2.3 below)  borrow from the Lender any
amount  up to but not to exceed  $10,000,000  in the  aggregate  at any one time
outstanding  (exclusive  of  interest,  fees or  other  charges  payable  by the
Borrower  under this  Agreement  and Note).  Borrowings  under the  Facility are
herein referred to collectively as the "Loans" and individually as a "Loan". The
Borrower  may use  the  Facility  by  borrowing,  repaying  and  reborrowing  in
accordance  with the terms and conditions of this  Agreement and the Note.  Each
request for a Loan may be made upon ten business  days' notice.  Each Loan shall
be deemed to be a  representation  and  warranty by the  Borrower on the date of
such Loan  that  immediately  prior to and after the  making of such Loan (i) no
Event of Default (as described in Section 2.1 below),  or event which,  with the
giving  of  notice  or  lapse  of time or both,  would  become  such an Event of
Default,  shall have  occurred and be  continuing  and (ii) no material  adverse
change in the financial condition, assets, business,  operations or prospects of
the Borrower shall have occurred,  and the truth and  correctness of each of the
foregoing  representations  when  deemed made is a  condition  precedent  to the
Lender's obligation to make such Loan.

     1.2 THE NOTE

     On or prior to the date on which the Lender  makes the initial  Loan to the
Borrower  under the  Facility,  the  Borrower  shall  execute and deliver to the
Lender the promissory note (the "Note") which follows this Agreement.

     The initial Loan and all subsequent Loans, and each payment made on account
of the principal thereof, shall be endorsed on the Note as of the date such Loan
is made or such payment is received by the Lender in immediately available funds
as provided in the Note. The Note shall be used to record all Loans and payments
of principal made under the Facility.

     1.3 VOLUNTARY PREPAYMENTS

     The  Borrower may prepay the Note in whole at any time or in part from time
to time without premium or penalty.  Partial prepayments of the Note shall be in
a minimum principal amount of $10,000 or any whole multiple thereof.


<PAGE>



     1.4 FINANCIAL INFORMATION

     The Borrower  hereby agrees to provide such  financial  information  to the
Lender as the Lender may reasonably request from time to time.


SECTION 2.  TERMINATION OF THE FACILITY

     2.1 EVENTS OF DEFAULT

     If the  Borrower  fails  to  perform  any  agreement  herein  contained  or
contained  in any other  agreement  with the Lender or if default  occurs in the
punctual  payment of any sum payable under the Note, this Agreement or any other
obligation of the Borrower to the Lender,  or if any  representation or warranty
deemed made  pursuant to Section 1.1 above shall be untrue or  incorrect  in any
respect,  or if any event described in paragraph 3 of the Note occurs;  then the
Facility  shall  automatically  terminate  and all Loans,  although not yet due,
shall become immediately due and payable without notice or demand.

     2.2 TERMINATION OR REDUCTION OF COMMITMENT

     The Borrower shall have the right, upon prior written notice to the Lender,
to  terminate  the  Facility in whole at any time or to reduce the amount of the
Facility  provided in Section 1.1 in part from time to time,  provided  that (a)
any  termination  of the Facility shall be accompanied by payment in full of the
unpaid principal amount of the Note, together with interest accrued thereon, and
(b)  partial  reductions  of the  Facility  shall be in the  minimum  amount  of
$25,000, and shall be accompanied by prepayment,  together with interest accrued
thereon to the date of the prepayment, to the extent, if any, that the aggregate
unpaid principal amount of the Note exceeds the Facility as then reduced.

     2.3 EXPIRATION DATE

     Unless  specifically  extended  by  the  Lender  in  writing  or  otherwise
terminated  under  Section 2.1 or Section 2.2, the Facility  shall expire on the
earlier of (x) May 30, 2001 or (y) the date  Borrower  raises  $10.0  million or
more through the sale of equity  securities  (the  "Expiration  Date"),  and all
amounts  outstanding  under this Agreement and the Note shall be due and payable
on the Expiration Date.


SECTION 3.  MISCELLANEOUS

     3.1 NO WAIVER

     The Borrower agrees that no failure to exercise and no delay in exercising,
on the part of the Lender, any right, power or privilege under this Agreement or
the Note  shall  operate  as a waiver  thereof;  nor shall any single or partial
exercise  of any right,  power or  privilege  under this  Agreement  or the Note
preclude  any other or further  exercise  thereof or the  exercise  of any other
right, power or privilege. The rights and remedies provided under this Agreement
and the Note are cumulative and not exclusive of any rights or remedies provided
by law. No  modification  or waiver of any  provision  of this  Agreement or the
Note, or any consent to any departure by the Borrower from the provisions hereof
or  thereof,  shall be  effective  unless the same shall be in writing  from the
Lender and then such waiver or consent  shall be effective  only in the specific
instance  and for the purpose for which it is given.  No notice to the  Borrower
shall  entitle the  Borrower to any other or further  notice in other or similar
circumstances unless expressly provided for herein. No course of dealing between
the Borrower  and the Lender  shall  operate as a waiver of any of the rights of
the Lender under this Agreement or the Note.

                                PROMISSORY NOTE

                                                                 Viena, Virginia


$ ----------------                         ----------------------,-------------,

     1. On the  Expiration  Date (as such term is defined in Section  2.3 of the
Credit  Facility  Agreement of even date  herewith  between the Borrower and the
Lender  (the  "Agreement")),   FOR  VALUE  RECEIVED,   Netrix  Corporation  (the
"Borrower")  promises to pay to the order of Steven T.  Francesco (the "Lender")
at his  address  provided  in the  Agreement,  in  United  States  dollars,  the
aggregate  unpaid  principal  amount of all Loans  (as such term is  defined  in
Section 1.1 of the Agreement) made by the Lender to the Borrower as shown on the
schedule attached hereto and made a part hereof (the "Schedule"),  together with
interest  (calculated  on the basis of a 360 day year for the  actual  number of
days  elapsed)  on the  unpaid  principal  amount  thereof  from  time  to  time
outstanding  at a rate per annum  equal to 5% above the prime  rate of  interest
published by THE WALL STREET JOURNAL from time to time as the prime rate, but in
no event in  excess  of the  maximum  rate  permitted  by  applicable  law.  Any
principal  amount  hereof  which is not paid when due  (whether  as  stated,  by
acceleration  or  otherwise)  shall bear interest for each day during the period
from and including the due date to the date of payment in full thereof at a rate
per annum equal to 2% above the rate in effect on such day. The Borrower  agrees
that interest  shall be payable on the last business day of each calendar  month
commencing on the first such date  occurring  after the date of this Note and on
any payment of  principal.  Any change in the  interest  rate  resulting  from a
change in the prime rate shall become effective as of the opening of business on
the day on which such change in such prime rate  occurs.  If any  payment  under
this Note  becomes due and  payable on a Saturday,  Sunday or other day on which
commercial Lenders are authorized to close under the laws of the Commonwealth of
Virginia, the maturity thereof shall be extended to the next succeeding business
day and interest  thereon  shall be payable at the  applicable  rate during such
extension.

     2. The Lender shall,  and is hereby  authorized by the Borrower to, endorse
on the Schedule and any continuations  thereof appropriate notations to evidence
the date and  principal  amount  of each  Loan and the date and  amount  of each
payment of principal  on the date such Loan is made or a payment in  immediately
available funds is received; provided that the Lender's failure to make any such
notation  shall not limit or otherwise  affect the  obligations  of the Borrower
hereunder  or under the  Agreement.  This Note shall be used to record all Loans
and payment of principal  made  hereunder and it shall  continue to be used even
though  there may be periods  when no amount of  principal  or interest is owing
hereunder. The Schedule and all continuations thereof shall be conclusive in the
absence of manifest error.

     3. If any of the  following  events of default  shall occur with respect to
the Borrower:  (a) the Borrower  shall fail to pay the principal of, or interest
on, this Note, or any other amount payable under this Note or the Agreement,  as
and when due and payable; (b) any representation or warranty made or deemed made
by the Borrower in this Note or in the  Agreement,  or which is contained in any
certificate,  document,  opinion,  financial or other statement furnished at any
time under or in connection with any this Note or the Agreement,  shall prove to
have been incorrect in any material  respect on or as of the date made or deemed
made;  (c) the Borrower  shall fail to perform or observe any term,  covenant or
agreement  contained in any Note or the Agreement on its part to be performed or
observed;  (d) the  Borrower  or shall  fail to pay  when  due any  indebtedness
(including but not limited to  indebtedness  for borrowed  money) or if any such
indebtedness  shall become due and payable,  or shall be capable of becoming due
and payable at the option of any holder thereof, by acceleration of its maturity
or if there shall be any default by the Borrower under any agreement relating to
such indebtedness; (e) the Borrower shall dissolve or for any reason cease to be
in existence;  or (f) the Borrower is involved in a proceeding  which may result
in a  forfeiture  of all or a  substantial  part of the  Borrower's  assets or a
material  judgment is entered  against the Borrower;  THEN, in any such case, if
the Lender shall elect by notice to the Borrower, the unpaid principal amount of
this Note and all Loans made hereunder,  together with accrued  interest,  shall
become  forthwith due and payable;  the unpaid principal amount of this Note and
all Loans made  hereunder,  together with accrued  interest,  shall  immediately
become due and payable without any notice or other action by the Lender.

     4. This Note is the Note referred to in the Agreement and is subject to the
terms and  conditions  thereof,  is entitled to the benefits  thereof and may be
prepaid as provided therein.

                              EMPLOYMENT AGREEMENT


      This Employment Agreement (the "Agreement"), effective as of January 4,
2000, is made and entered by and between Greg McNulty (the "Executive") and Nx
Networks Corporation, a Delaware corporation (the "Company").

                                    AGREEMENT

      WHEREAS, the Company desires to engage the Executive to provide
services pursuant to the terms of this Agreement; and

      WHEREAS, the Executive desires to provide such services to the Company
pursuant to the terms of this Agreement;

      NOW, THEREFORE, in consideration of the foregoing and of the respective
covenants and agreements set forth below, the parties hereto agree as follows:

1.    TERM OF EMPLOYMENT.
      ------------------

      The term of the Executive's employment under this Agreement shall commence
immediately upon the execution of this Agreement and end on the third
anniversary of such date (the "Term of Employment"). If the Company or the
Executive does not deliver to the other party at least 60 days prior written
notice that the Term of Employment shall end on the third anniversary of the
date hereof, the Term of employment shall automatically continue for an
additional one-year period. At the end of such one year period, the Term of
employment shall automatically continue for successive one year terms unless
either party delivers at least 60 days prior written notice that the Term or
employment shall end at the end of such one-year renewal period.

2.    DUTIES.
      ------

      (a) During the Term of Employment, the Executive shall serve as the
Executive Vice President-Worldwide Sales and Marketing of the Company with such
authority and duties as are generally associated with such position and as may
be assigned to him from time to time by the Board of Directors of the Company
that are consistent with such authority and duties. The Executive shall report
to the President of the Company.

      (b) During the Term of Employment the Executive shall devote his full
business time and best efforts to the business and affairs of the Company.
Nothing in this Agreement shall preclude the Executive from engaging in
charitable and community affairs so long as such activities, in the reasonable
determination of the Board of Directors of the Company, do not interfere with
the execution of his duties and responsibilities hereunder or from serving,
subject to the prior approval of the Board of Directors (not to be unreasonably
withheld), as a director or trustee of any other corporation, association or
entity.

<PAGE>

3.    COMPENSATION AND RELATED MATTERS.
      --------------------------------

      (a) SALARY. During the Term, the Executive shall receive a base salary
(the "Base Salary") at the rate of $200,000 per annum. Such Base Salary shall be
payable in accordance with the Company's policies in effect from time to time,
but in any event no less frequently than monthly. The Board of Directors from
time to time may increase, but not decrease, the Base Salary.

      (b) BONUS. The Executive shall be eligible for an annual bonus in such
amount as the Board of Directors may designate. Payment of any annual bonus
shall be made at the same time that other senior-level executives receive their
bonus but in no event later than April 21 of the following year to which such
bonus relates.

      (c)   STOCK OPTIONS.
            -------------

            (i) To induce the Executive to enter into this Agreement, the
      Executive is hereby granted an option (the "Stock Option") by the Company
      to purchase 250,000 shares of common stock, par value $0.05 per share, of
      the Company (the "Common Stock"). The Stock Option shall be memorialized
      in a separate stock option agreement, dated the date hereof, between the
      Company and the Executive. The exercise price of the Stock Options will be
      $6.00 per share of Common Stock. The Stock Options shall vest over time as
      follows and be subject to earlier vesting as described below.

      Time vesting:
            50,000 on the date hereof, and 50,000 semi-annually thereafter.

      Accelerated vesting:
            NO. SHARES  VESTING EVENT
            50,000            Common Stock trades at $35/share for 10
                                consecutive trading days
            50,000            Common Stock trades at $40/share for 10
                                consecutive trading days
            50,000            Common Stock trades at $45/share for 10
                                consecutive trading days
            50,000            Common Stock trades at $50/share for 10
                                consecutive trading days

            (ii) Additional stock option compensation will be granted to the
      Executive if the Company achieves targeted levels of annual gross revenue
      (the "Target Revenue"). With respect to the calendar year ending December
      31, 2000, the Target Revenue is $50 million. In each subsequent year the
      Target Revenue will be 120% of the actual gross revenue of the Company for
      the immediately preceding year (prorated for a partial year, if
      applicable, in the last year of this Agreement). If for any calendar year
      the Company's gross revenue exceeds the Target Revenue for that year, then
      the Executive will be granted additional options at the rate of 1 option
      for each $40 of such excess revenue. The determination of the Company's
      gross revenues for each year will be based upon its audited financial
      statements, as reflected in the Company's Annual Report on Form 10-K, but
      subject to adjustment by the President to reflect any gross revenues
      booked at calendar year-end but determined by him in good faith not to be
      collectible. Each such grant of additional stock options shall be made
      promptly after the audited financial statements become available, and

                                       2

<PAGE>

      shall be memorialized in a separate stock option agreement, dated the
      grant date, between the Company and the Executive. The exercise price of
      each option shall be the market price of the Common Stock on the date of
      grant. The additional stock options shall vest in four equal semi-annual
      installments with the first such installment vesting on the six-month
      anniversary of the grant date. The Target Revenue for any year may be
      adjusted by the Compensation Committee of the Board of Directors, as the
      Committee may deem appropriate in its good faith determination, to take
      into account acquisitions or divestitures of business or business lines by
      the Company. Notwithstanding the foregoing, no grant of additional stock
      options will be made under this Section 3(c)(ii) for any year in which a
      Change in Control of the Company, as defined in the Company's 1999 Long
      Term Incentive Plan, occurs or in any year subsequent to a Change of
      Control.

            (iii) The Company shall use its best efforts to register the Common
      Stock underlying the options referred to in this Section 3(c) on
      Securities and Exchange Commission Form S-8, including the registration of
      any shares underlying stock options vested prior to the date of filing
      such Form S-8.

      (d) EXPENSES. The Executive is authorized to incur reasonable expenses in
carrying out his duties and responsibilities under this Agreement and the
Company shall promptly reimburse him for all business expenses incurred in
connection therewith, subject to documentation in accordance with the Company's
policy.

      (e)   OFFICE ALLOWANCE.  The Company shall reimburse the Executive for
an office expense up to a maximum of $10,900 per year, prorated for partial
years.

      (f) EMPLOYEE BENEFITS. During the Term of Employment, the Executive shall
be entitled to participate in or receive benefits under any and all employee
benefit plans, programs and arrangements on terms no less favorable than those
generally applicable to senior executives of the Company, subject to and on a
basis consistent with the terms, conditions and overall administration of such
employee benefit plans, programs and arrangements. The Executive shall also be
eligible to participate in the Company's executive perquisites in accordance
with the terms and provisions of the arrangements as in effect from time to time
for the Company's senior executives. The Executive will receive a medical
insurance coverage family plan as offered to other Executives. For the term of
his employment, said medical insurance coverage shall be for the maximum
coverage available for said medical coverage. The Executive shall also receive
the sum of $500.00 per month for automobile allowance during the term of
employment. The Executive will receive life insurance coverage as comparable to
that which is offered to any other executive.

      (g) VACATION. The Executive shall be entitled to four weeks of paid
vacation for each 12-month period during the Term of Employment, which shall be
taken at such times and intervals as shall be determined by the Executive,
subject to the reasonable business needs of the Company. The Executive shall
also be entitled to the paid holidays and other paid leave set forth in the
Company's policies.

                                       3

<PAGE>

      (h) PAYMENT UPON CHANGE OF CONTROL. In the event of a Change in Control of
the Company, as defined in the Company's 1999 Long Term Incentive Plan, the
Company shall issue to the Executive 200,000 shares of Common Stock (or, if the
Common Stock was modified, exchanged or converted in connection with such Change
of Control, the cash, securities or other property that such 200,000 shares
would represent at the time of the Change of Control if they had been modified,
exchanged or converted in connection with such Change of Control). Such Common
Stock will be registered by the Company at the time of, or as soon as possible
after, such issuance.

4.    TERMINATION OF EMPLOYMENT.
      --------------------------

      (a) TERMINATION DUE TO DEATH. In the event the Executive's employment is
terminated due to his death, his estate or his beneficiaries, as the case may
be, shall be entitled to and their sole remedies under this Agreement shall be:

          (i)   Base Salary through the date of death which shall be paid in a
                single lump sum not later than 45 days following the Executive's
                death;

          (ii)  the balance of any bonus awarded and earned but not paid at the
                time of termination, which shall be paid in a single lump sum

          (iii) other or additional benefits then due or earned in accordance
                with applicable plans and programs of the Company.

      (b) TERMINATION DUE TO DISABILITY. In the event the Executive becomes
Disabled (as defined below), the Company may terminate his employment upon
notice to that effect. Upon such a termination, the Executive or is
representative, as the case may be, shall be entitled to, and their sole
remedies under this Agreement shall be:

          (i)   Base Salary through the date of termination, which shall be paid
                in a single lump sum not later than 45 days following such
                termination;

          (ii)  the balance of any bonus awarded and earned but not paid at the

          (iii) other or additional benefits then due or earned in accordance
                with applicable plans and programs of the Company.

For the purpose of this subsection, the Executive shall have a "Disability" at
such time as he becomes entitled to benefits under the Company's long-term
disability insurance plan as in effect from time to time.

      ---------------------------------

      The Executive acknowledges that his employment with the Company will, of
necessity, provide him with specialized, unique knowledge and confidential
information and that, in light of the competitive nature of the Company's
business, the Company could be harmed if such knowledge and information were
used in competition with the Company. The Executive further acknowledges that

obligations under this Agreement without the Executive's agreement to the

of not more than three percent (3%) of the issued and outstanding stock of any

solicited or to whom he catered or with whom he became acquainted after entering
the employ of the Company.

Company's senior level employees with whom he had contact prior to such
termination of employment or (ii) solicit or encourage any such senior level
employee to seek or accept employment with any other person or entity.

      (d) The Executive represents and warrants that the knowledge, skills and
abilities he currently possesses are sufficient to permit him, in the event of
his termination of employment hereunder for any reason, to earn a livelihood

            (iii) in the case of a termination of the Executive's employment
                  pursuant to Section 4(e) above, the date of such termination;
                  PROVIDED, HOWEVER, that within 10 days after the Executive
                  announces that he will not renew his employment hereunder at
                  the end of the then current Term of Employment the Company may
                  notify the Executive that it will cause the Restriction Period
                  to be 12 months and, in consideration for such period, the

      ----------------

      (a) The Company agrees that if the Executive is made a party, or is
threatened to be made a party, to any action, suit or proceeding, whether civil,
criminal, administrative or investigative (a "Proceeding"), by reason of the
fact that he is or was a director, officer or employee of the Company or any
subsidiary or is or was serving at the request of the Company or any subsidiary
as a director, officer, member, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, whether or not the basis of such Proceeding
is the Executive's alleged action in an official capacity while serving as a
director, officer, member, employee or agent, the Executive shall be indemnified
and held harmless by the Company to the fullest extent legally permitted or
authorized by the Company's certificate of incorporation or bylaws or
resolutions of the Company's certificate of incorporation or by laws or
resolutions of the Company's Board of Directors or, if greater, by the laws of
the State of Delaware, against all cost, expense, liability and loss (including,

                                       10

<PAGE>


without limitation, attorney's fees, judgments, fines, ERISA excise taxes or

suffered by the Executive in connection therewith, and such indemnification

member, officer, employee or agent of the Company or other entity and shall
inure to the benefit of the Executive's heirs, executors and administrators. The
Company shall advance to the Executive all reasonable costs and expenses
incurred by him in connection with a Proceeding within 20 days after receipt by
the Company of a written request for such advance. Such request shall include an
undertaking by the Executive to repay the amount of such advance if it shall
ultimately be determined that he is not entitled to be indemnified against such
costs and expenses.

      (b) Neither the failure of the Company (including its board of directors,
independent legal counsel or stockholders) to have made a determination prior to
the commencement of any proceeding concerning payment of amounts claimed by the
Executive under Section 9(a) above that indemnification of the Executive is
proper because he has met the applicable standard of conduct, nor a
determination by the Company (including its board of directors, independent
legal counsel or stockholders) that the Executive has not met such applicable
standard of conduct, shall create a presumption that the Executive has not met
the applicable standard of conduct.

      (c) The Company agrees to continue and maintain a directors and officers'
liability insurance policy covering the Executive to the extent the Company
provides such coverage for its other executive officers.

10.   EFFECT OF AGREEMENT ON OTHER BENEFITS.
