         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.    BASIS OF PRESENTATION:

         Netrix Corporation ("Netrix" or the "Company") is a worldwide provider
of voice and data networking products. Netrix develops, manufactures, markets,
and supports networking equipment for voice, data, and image networks. Netrix
products are designed to transport voice over data networks to enable its
customers to realize significant cost savings. Netrix was incorporated in 1985.
The Company conducts operations in the United Kingdom and Hong Kong through its
wholly owned subsidiary, Netrix International Corporation (a Delaware
corporation), and in Germany and Italy through its wholly owned subsidiaries
Netrix GmbH and Netrix S.r.l., respectively. These condensed consolidated
financial statements include the accounts of the Company and its subsidiaries.
All significant intercompany transactions have been eliminated.

         The Company's operations are subject to certain risks and uncertainties
including, among others, rapidly changing technology and markets, current and
potential competitors with greater financial, technological, production and
marketing resources, reliance on certain sole source suppliers and third party
contract manufacturers, and dependence on key management personnel.

         The unaudited condensed financial statements included herein have been
prepared by the Company, without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission and include, in the opinion of
management, all adjustments, consisting of normal, recurring adjustments,
necessary for a fair presentation of interim period results. Certain information
and footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations. The Company believes, however,
that its disclosures are adequate to make the information presented not
misleading. The results for such interim periods are not necessarily indicative
of results to be expected for the full year.

         RISKS AND OTHER IMPORTANT FACTORS

         For the three months ended June 30, 1999, the Company reported revenues
of approximately $6.0 million and a net loss of approximately $2.5 million,
compared to revenues of approximately $7.8 million and a net loss of
approximately $2.8 million for the three months ended June 30, 1998. For the six
months ended June 30, 1999, revenues were approximately $13.3 million and the
net loss was approximately $3.8 million, compared to revenues of approximately
$15.1 million and a net loss of approximately $3.8 million for the six months
ended June 30, 1998.

         On May  14,1999 the Company  completed a private  placement  by selling
approximately  298,187 shares of Series A 8% Convertible  Preferred  Stock,  par
value $.05 per share,  at a price of $13.75 per share.  Each share of  preferred
stock has a liquidation preference equal to its purchase price, plus accrued and
unpaid  dividends.  Dividends are cumulative  from May 14, 1999, and are payable
semi-annually,  in arrears, on April 30 and October 31 of each year,  commencing
October 31, 1999.  Dividends are payable in cash or shares of Common  Stock,  at
the Company's election.  The Preferred Stock is convertible at any time prior to
redemption,  at the option of the holder, into Common Stock at a conversion rate
equal to five shares of Common Stock for each share of Preferred Stock,  subject
to adjustment in certain circumstances.  The fair value of the Preferred Stock's
beneficial  conversion  feature,   reflective  of  the  difference  between  the
conversion  price of the Preferred  Stock and the market value of the underlying
Common  Stock on the date of issue,  constitutes,  for  accounting  purposes,  a
dividend by the Company.  We estimate the dividend to be $1.2  million.  We will
reflect  the  dividend  as a non-cash  charge to  earnings  in our  consolidated
statements of earnings in connection with the lapse of the transfer restrictions
on the  underlying  Common Stock,  beginning in August 1999 and through May 2000
when all restrictions lapse . The Preferred Stock is redeemable at the option of
the Company at any time after the closing bid price for the Common  Stock on the
NASDAQ Stock  Market has equaled or exceeded  $6.00 for 10  consecutive  trading
days. The redemption price is $17.50 per share plus accrued but unpaid dividends
to the date of repurchase.

         In connection with the private placement, the Company received net
proceeds of approximately $4.0 million to be used to fund operations, severance
and other restructuring activities, and marketing and sales initiatives. On June
15, 1999 the Company filed with the Securities and Exchange Commission (SEC) a

                                       5
<PAGE>

registration statement covering the resale of the Common Stock underlying the
Preferred Stock. The Company is to undertake all reasonable efforts to cause the
registration statement to be declared effective by the SEC within 90 days after
filing.

         As a result of the combination of the net loss for the quarter and the
proceeds of the private placement, the Company's tangible net worth increased
from $9.9 million at March 31, 1999 to $11.6 million at June 30, 1999. The
Company's initial line of credit agreement negotiated in November 1997 required
it to maintain a tangible net worth of at least $13.5 million measured at the
end of each month. Between October 31, 1998 and March 31, 1999 the Company was
in violation of this covenant. This covenant violation allowed the Company's
lending institution to call for collection of the outstanding loan balance. On
April 12, 1999 the lending institution granted the Company a waiver of past
covenant violations and waived its right to call the line of credit for these
covenant violations. The lending institution amended the line of credit
agreement to measure the Company's tangible net worth on a quarterly basis
effective January 1, 1999, and set the minimum tangible net worth covenant at
$9.8 million as of March 31, 1999 and $9.0 million for all subsequent quarters.
At March 31, 1999 and June 30, 1999, the Company was in compliance with the new
covenant, and management believes that this new covenant will be adequate for
the Company to operate under in the foreseeable future. However, there can be no
assurances that the Company will not violate the new covenant or that the
outstanding loan balance will not be called by the lending institution upon
violation of the new covenant.

         The success and the future of the Company is dependent on its ability
to generate net income or to increase its net worth by the sale of additional
equity. The Company's ability to generate net income is in large part dependent
on its success at increasing sales of its new products and/or controlling costs.
The Company's plan to increase revenues through sales of its Network Exchange
product line is continuing to evolve in order to exploit new marketing channels;
however, due to market conditions, competitive pressures, and other factors
beyond its control, the Company has been unable to achieve sufficient
incremental growth in new product sales to generate net income and there can be
no assurances that the Company will be able to adequately increase new product
sales and generate net income in the future.

         The success of the Company is dependent on its ability to generate
adequate cash for operations and capital needs. Its ability to generate adequate
cash for such needs is in part dependent on its success at increasing sales of
its products. The Company's plan is to increase revenues through sales of its
Network Exchange product line; however, due to market conditions and other
factors beyond its control, there can be no assurance the Company will be able
to adequately increase product sales. Therefore, the Company may have to
generate additional cash through the sale of assets, including technologies or
the sale of debt or equity securities. Although the Company believes it has the
ability to generate additional cash through such sales, such sales may be
dilutive and there can be no assurances that adequate funds will be available or
available on terms that are reasonable or acceptable to the Company. If the
Company is unable to generate adequate cash, there could be a material and
adverse effect on the business and financial condition of the Company. The
Company has implemented cost control measures and is continually evaluating
expense levels to mitigate its liquidity risk.

         For the six months ended June 30, 1999 and June 30, 1998, the Company's
operating activities used approximately $713,000 and $3.6 million of cash,
respectively. The cash used by operations was primarily due to continued net
losses from operations. The success of the Company is also dependent on its
ability to generate adequate cash for operations and capital needs. At June 30,
1999, the Company had approximately $3.9 million in cash and cash equivalents
with approximately $428,000 outstanding of the approximately $1.4 million
available under the line of credit agreement. The Company is relying on future
sales and the collection of the related accounts receivable to meet its cash
obligations. The Company may be unable to meet these obligations as they become
due and may be required to curtail its operations. If the Company is required to
curtail its operations there can be no assurances that the carrying value of the
Company's assets will be fully realized.

         The Company may have to generate additional equity or cash through
other means, which may include the sale of assets, including intellectual
property and proprietary technology, the sale of equity, additional borrowings,
the sale of selected operations, or one or more strategic partnerships. Although
the Company believes it has the ability to generate additional equity and cash
through such sales, such sales may be dilutive and there can be no assurances

                                       6

<PAGE>

that adequate funds will be available, or available on terms that are reasonable
or acceptable to the Company. If the Company is unable to generate additional
equity and adequate cash, there will be a material and adverse effect on the
business and financial condition of the Company, to the extent that a sale,
liquidation or restructuring of the Company will be required, in whole or in
part.

         Future operating results may be affected by a number of other factors
including the timing of new products in the market place, competitive pricing
pressures and economic conditions. As the market for the Company's products is
characterized by rapidly changing technology, the development, introduction and
evolution of competitive products may require a significant investment of
financial resources. Additionally, the Company relies on reseller channels that
are not under its control for a significant portion of its revenues,
particularly in its international regions. Also, while the Company has generally
been able to obtain adequate supplies of components to date, the interruption or
termination of the Company's current manufacturing relationships could have an
adverse effect on the Company's operating results.

2.    NEW ACCOUNTING PRONOUNCEMENTS:

         In June 1997, the Financial Accounting Standards Board issued SFAS No.
130, "Reporting Comprehensive Income" and SFAS No. 131, "Disclosure about
Segments of an Enterprise and Related Information. "SFAS No. 130 requires that
an enterprise (a) classify items of other comprehensive income by their nature
in a financial statement and (b) display the accumulated balance of other
comprehensive income separately from retained earnings and additional
paid-in-capital in the equity section of a statement of financial position.
The Company implemented SFAS No. 130 in the first quarter of 1998, and it did
not have a material impact on the financial statements.  SFAS No. 131 requires
the Company to report financial and descriptive information about its reportable
operating segments.  The Company adopted SFAS No. 131 for the year ended
December 31, 1998.

3.    CASH EQUIVALENTS:

         Cash equivalents are primarily bank deposits, commercial paper, and
government agency securities with original maturities of three months or less.
These investments are carried at cost which approximates market value.

4.    INVENTORIES:

5.    COMMITMENTS AND CONTINGENCIES:

             LINE OF CREDIT

         In November 1997, the Company negotiated a $3.0 million line of credit
agreement with a lending institution to be used for working capital. This
agreement provided for interest at a per annum rate equal to the lender's prime
rate plus 2%, subject to a minimum monthly interest based on 40% utilization of
$3.0 million. In August 1998, as a result of concerns about the deterioration of
aged international accounts receivable, the Company's lending institution
eliminated international receivables as qualified accounts receivable for
borrowing collateral. The lending institution also increased the interest rate
for outstanding loan amounts to prime plus 3 1/2% from prime plus 2%. In October
1998, the lending institution reinstated a sub-line of credit up to an amount of
$600,000 for selected foreign accounts receivable.

                                       7

<PAGE>

         The Company's initial line of credit agreement negotiated in November
1997 required it to maintain a tangible net worth covenant of at least $13.5
million measured at the end of each month. Between October 31, 1998 and March
31, 1999 the Company was in violation of this covenant. This covenant violation
allowed the Company's lending institution to call for collection of the
outstanding loan balance. On April 12, 1999 the lending institution granted the
Company a waiver of past covenant violations and waived its right to call the
line of credit for these covenant violations. The lending institution amended
the line of credit agreement to measure the Company's tangible net worth on a
quarterly basis effective January 1, 1999, and set the minimum tangible net
worth covenant at $9.8 million as of March 31, 1999 and $9.0 million for all
subsequent quarters. At June 30, 1999, the Company was in compliance with the
new covenant, and management believes that this new covenant will be adequate
for the Company to operate under in the foreseeable future. However, there can
be no assurances that the Company will not violate the new covenant or that the
outstanding loan balance will not be called by the Company's lending institution
upon violation of the new covenant. Concurrent with the April 1999 waiver of
default, the lending institution extended the line of credit agreement to May
31, 2001. In connection with the waiver of default and extension of the line of
credit agreement, the Company granted the lending institution 50,000 warrants to
purchase Common Stock at an exercise price of $2.00 per share. During the
quarter ended March 31, 1999, the Company recognized additional interest charges
of $97,000 in relation to the fair value of these warrants.

         Borrowings under the line are based on qualified domestic accounts
receivable and are collateralized by the Company's assets. At June 30, 1999, the
Company had approximately $428,000 outstanding of the approximately $1.4 million
available under the line of credit agreement. At December 31, 1998, the Company
had approximately $2.2 million outstanding of the approximately $2.4 million
available under the line of credit.

6.   SEGMENT INFORMATION:

         For the year ended December 31, 1998, the Company adopted the Statement
on Financial Accounting Standards ("SFAS") No. 131, "Disclosures about Segments
of an Enterprise and Related Information". The Company's two reportable segments
are products and services. The Company evaluates the performance of its segments
based on gross profit. Under SFAS No. 131, the Company is required to provide
enterprise-wide disclosures about revenues by segment, long-lived assets by
geographic area and revenues from major customers.

7.    RESTRUCTURING CHARGE:

                                       9

<PAGE>


         In April 1999, the Company implemented a restructuring of operations to
reduce and economize its work force as part of an overall plan to return to
profitability. The restructuring charges of $900,000 resulted from approximately
$843,000 of accrued severance and benefit costs associated with a
reduction-in-force of approximately 36 employees across all functional areas of
the Company, and approximately $57,000 of accrued facility costs resulting from
the consolidation of facilities and premature termination of various office
leases. As of June 30, 1999, severance of approximately $493,000 and lease
termination costs of approximately $57,000 have been paid, and the remaining
severance payments of approximately $350,000 will occur over approximately a six
month period. The Company also paid approximately $100,000 of final severance
payments to certain international employees that resulted from an April 1997
restructuring of operations.

8.     FOREIGN CURRENCY EXCHANGE GAIN:

         Generally, assets and liabilities denominated in foreign currencies are
translated into US dollars at current exchange rates. Operating results are
translated into US dollars using the average rates of exchange prevailing during
the period. Gains or losses resulting from translation of assets and liabilities
are included in the cumulative translation adjustment account in stockholders'
equity, except for the translation effect of intercompany balances that are
anticipated to be settled in the foreseeable future. The Company had no foreign
exchange gains or losses for the first half of 1999, and had a net translation
gain of approximately $47,000 for the first half of 1998.

9.    BASIC AND DILUTED EARNINGS (LOSS) PER SHARE:

         Basic earnings (loss) per share amounts are computed using the weighted
average number of common shares. Diluted earnings (loss) per share amounts are
computed using the weighted average number of common shares and common
equivalent shares having a dilutive effect during the periods; however, for the
three and six months ended June 30, 1999 and 1998, the effect of common stock
equivalents has not been considered as they would have been antidilutive.

10.      STOCKHOLDERS' EQUITY

         On May 14,1999 the Company completed a private placement by selling and
issuing approximately 298,187 shares of Series A 8% Convertible Preferred Stock,
par  value  $.05 per  share,  at a price of $13.75  per  share,  and by  issuing
warrants to purchase an  additional  49,818 share of Common Stock at an exercise
price of $2.75 per  share.  Each  share of  Preferred  Stock  has a  liquidation
preference  equal to its  purchase  price,  plus  accrued and unpaid  dividends.
Dividends are cumulative  from May 14, 1999, and are payable  semi-annually,  in
arrears,  on April 30 and October 31 of each year,  commencing October 31, 1999.
Dividends  are  payable  in cash or  shares of Common  Stock,  at the  Company's
election. The Preferred Stock is convertible at any time prior to redemption, at
the option of the holder,  into Common Stock at a conversion  rate equal to five
shares of Common Stock for each share of Preferred Stock,  subject to adjustment
in certain  circumstances.  The fair value of the Preferred  Stock's  beneficial
conversion feature, reflective of the difference between the conversion price of
the Preferred  Stock and the market value of the underlying  Common Stock on the
date of issue, constitutes,  for accounting purposes, a dividend by the Company.
We estimate the dividend to be $1.2  million.  We will reflect the dividend as a
non-cash  charge to  earnings  in our  consolidated  statements  of  earnings in
connection with the lapse of the transfer  restrictions on the underlying Common
Stock,  beginning  in August  1999 and  through  May 2000 when all  restrictions
lapse.  The  Preferred  Stock is  redeemable at the option of the Company at any
time after the closing bid price for the Common Stock on the NASDAQ Stock Market
has equaled or exceeded  $6.00 for 10  consecutive  trading days. The redemption
price is $17.50  per share plus  accrued  but  unpaid  dividends  to the date of
repurchase.  In connection with the private placement,  the Company received net
proceeds of approximately $4.0 million to be used to fund operations,  severance
and other restructuring activities, and marketing and sales initiatives. On June
15, 1999 the Company filed with the Securities and Exchange  Commission  (SEC) a
registration  statement  covering the resale of the Common Stock  underlying the
Preferred Stock. The Company is to undertake all reasonable efforts to cause the
registration  statement to be declared effective by the SEC within 90 days after
filing.

NETRIX CORPORATION

    ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                         AND RESULTS OF OPERATIONS

            This Quarterly Report on Form 10-Q contains forward-looking
statements. For this purpose, any statements contained herein that are not
statements of historical fact may be deemed to be forward-looking statements.
Without limiting the foregoing, the words "believes," "anticipates," "plans,"
"expects" and similar expressions are intended to identify forward-looking
statements. There are a number of important factors that could cause the
Company's actual results to differ materially from those indicated by such
forward-looking statements. These factors include, without limitation, those set
forth below under the caption "Certain Factors That May Affect Future Results".

RESULTS OF OPERATIONS

         RECENT DEVELOPMENTS. The company announced on April 21, 1999 the
appointment of two senior telecommunications executives to its board of
directors. The additions of Douglas J. Mello and Richard Yalen, formerly of The
Bell Atlantic Corporation (NYSE: BEL) and Cable and Wireless, USA (NYSE: CWP),
respectively, expands the Netrix board from 4 to 6 members. The appointments
reflect a recruitment strategy adopted by the Company's new Chairman, Steven T.
Francesco, to attract to the Board of Directors senior executives with
significant telecommunications industry experience and contacts. Both Mello and
Yalen have led telecommunications service providers that are deploying voice and
data networks based on ATM, frame relay and voice over Internet protocol.

         The board also formed two new oversight committees.  Board members
Richard Yalen and William T. Rooker, Jr. will head the audit committee, and
John Faccibene and Douglas Mello will direct the company's compensation
committee.

         The Company announced on April 26, 1999 that its newly elected Board of
Directors is overseeing an immediate operational restructuring as part of an
overall plan to return to profitability. The effort is focusing on a reduction
of fixed costs, outsourcing non-critical manufacturing and services, and an
accelerated phase-out of older/low margin products. In addition, Netrix is
aggressively expanding its direct sales force and focusing on service providers
such as ISP's, CLEC's and telecommunication carriers. In connection with the
operational restructuring, the Company has implemented a reduction-in-force
that, when combined with previous actions, has reduced headcount approximately
25% across all functional areas since the beginning of 1999.

         The Company announced on May 11, 1999, that Stephen T. Francesco,
Chairman, was appointed CEO, and that Lynn C. Chapman will maintain his position
as President and assume the role of COO.

         On May 14,1999 the Company completed a private placement by selling
approximately 298,187 shares of Series A 8% Convertible Preferred Stock, par
value $.05 per share, at a price of $13.75 per share. In connection with the
private placement, the Company received net proceeds of approximately $4.0
million to be used to fund operations, severance and other restructuring
activities, and marketing and sales initiatives.

         On June 16, 1999, the Company announced the appointment of a senior
Microsoft executive to the board. Mr. Greg McNulty has over 23 years of
experience in the high technology sales and marketing environment, and is Senior
Group Manager of Business Development for Microsoft-Web TV Network Services
managing Web TV's relationships with RBOC's, ILEC's, CLEC's, and ISP's.

                                       12

<PAGE>

         On July12, 1999, the Company issued a joint press release with Sonus
Communications, Inc. announcing a significant milestone in the development of
the Voice Over Internet Protocol (VoIP) telephony market. The VoIP services that
Sonus Communications provides for telecommunications carriers to China using
Netrix' 2210 Series Gateways is now comparable in terms of voice quality,
connect rates and dial tone delay with direct service from China Telecom, at an
average 30 percent lower base cost to carriers.

         On July 27, 1999, the Company announced the appointment of Sean Rooney
as Senior Vice President of Sales. Rooney, formerly General manager of
Diversified markets for Sony Electronics, Inc., will lead a staff of 20
salespeople including 15 newly-acquired professionals from industry competitors.

         On August 5, 1999, the Company announced the appointment of Peter J.
Kendrick as Vice president and Chief Financial Officer, replacing Norman Welsch
in his day to day activities. Mr. Kendrick joins the Company with 16 years
experience as a CFO and former investment banker with a background in financial
operations, initial public offerings and mergers and acquisitions.

         BACKGROUND. The results for second quarter and first half of 1999
reflect an overall decrease in the revenues and expenses of the Company from the
comparable period in 1998. During the first half of 1999, Netrix continued to
experience a decline in revenues in the product line it acquired from Republic
Telcom, and a net increase in its new products, the 2210, which combines the
Republic technology with Netrix switching capability, and the 2550, Netrix
enhanced switching platform. Geographically, during the first half of 1999, the
Company continued to experience declining revenues from International customers,
which was partially offset by an increase in revenues from Domestic customers.

         In April 1999, the Company implemented a restructuring of operations to
reduce and economize its work force as part of an overall plan to return to
profitability. The restructuring charges of $900,000 resulted from approximately
$843,000 thousand of accrued severance and benefit costs associated with a
reduction-in-force of approximately 36 employees across all functional areas of
the Company, and approximately $57,000 of accrued facility costs resulting from
the consolidation of facilities and premature termination of various office
leases. The reduction-in-force and payment of severance will occur over
approximately a six-month period.

         REVENUES. For the three months ended June 30, 1999, revenues were
approximately $6.0 million, a decrease of approximately $1.8 million, or 23%,
compared to revenues of approximately $7.8 million for the three months ended
June 30, 1998. The quarterly decrease in revenues was due to a combined decrease
in product revenues of approximately $924,000, or 17%, to $4.5 million, and a
decrease in service revenues of approximately $895,000, or 37%, to $1.5 million.
For the six months ended June 30, 1999, revenues were approximately $13.3
million, a decrease of approximately $1.7 million, or 12%, compared to revenues
of approximately $15.1 million for the six months ended June 30, 1998. The
decrease in product revenues for the three and six month periods is the net
result of a decrease in revenues from older products, which was partially offset
by higher revenues from the 2210 and 2550 series products. The decrease in
service revenues is the result of cancellations and non-renewals of maintenance
contracts by various customers using legacy equipment.


                                       13
<PAGE>

         GROSS PROFIT. For the three months ended June 30, 1999, gross profit
decreased by approximately $1.2 million, or 30%, to approximately $2.7 million,
down from approximately $3.9 million in the year earlier quarter. As a
percentage of revenues, gross profit was approximately 46% and 50% for the
quarters ended June 30, 1999 and 1998, respectively, an overall decrease of
approximately 4% of revenues. Product gross profit decreased from approximately
52% in the second quarter of 1998 to approximately 51% in the second quarter of
1999. The gross profit for service revenues decreased from approximately 44% in
the second quarter of 1998 to approximately 30% in the second quarter of 1999.
For the six months ended June 30, 1999, gross profit decreased by approximately
$1.7 million, or 22%, to approximately $5.9 million, down from approximately
$7.6 million in the year earlier period. As a percentage of revenues, gross
profit was approximately 45% and 51% for the six months ended June 30 1999 and
1998, respectively, an overall decrease of approximately 6% of revenues. Product
gross profit decreased from approximately 55% in the first half of 1998 to
approximately 51% in the first half of 1999. The three and six month decrease in
product gross profit is primarily the combined result of a lower-margin product
mix of shipments, a greater proportion of sales made through distributors, which
generally have higher discounts than direct retail sales, and competitive
pricing pressures. The gross profit in any particular quarter is dependent upon
the mix of products sold and the channels of distribution. As a result, the
gross profit on a quarter to quarter basis can vary within a wide range. The
gross profit for service revenues decreased from approximately 41% in the first
half of 1998 to approximately 26% in the first half of 1999. The three and six
month decrease in service gross profit is primarily the result of lower service
revenues that were partially offset by a reduction in service costs.

         SALES AND MARKETING. Sales and marketing expenses decreased by
approximately $2.5 million, or 64%, to approximately $1.4 million for the second
quarter of 1999, down from approximately $3.9 million for the second quarter of
1998. The quarterly decrease is the result of reduced bad debt expenses of
approximately $1.1 million, reduced personnel costs of approximately $625,000,
reduced marketing materials expenditures of approximately $300,000, reduced
travel costs of approximately $160,000, lower consigned equipment obsolescence
write-offs of approximately $200,000, and other cost reductions of approximately
$150,000. For the first half of 1999, sales and marketing expenses were
approximately $3.0 million, a decrease of approximately $3.0 million, or 50%,
when compared to the six month period a year earlier. The quarter and year over
year decreases are the result of a decrease in sales and marketing personnel in
international and domestic operations, and curtailment of trade show
initiatives, advertising and marketing collateral, combined with higher expenses
in 1998 associated with new product rollouts.

         RESEARCH AND DEVELOPMENT. For the three months ended June 30, 1999,
research and development expenses were approximately $1.7 million, equivalent to
the three months ended June 30, 1998. For the six months ended June 30, 1999,
research and development expenses were approximately $3.4 million, up
approximately $115,000, or 4%, from the year earlier period. The year over year
increase in research and development expenses is due primarily to an increase in
personnel costs of approximately $100,000. All of the Company's research and
development costs were charged to operations as incurred during the periods
reported.

         GENERAL AND ADMINISTRATIVE. General and administrative (G&A) expenses
for the three and six months ended June 30, 1999 were approximately $1.2 million
and $2.3 million, respectively, compared to approximately $1.1 million and $2.2
million in the corresponding year earlier periods. The increase in G&A was the
result of higher accounting and legal expenses associated with the restructuring
of operations and the renegotiation of the line of credit and default waiver
with the Company's lending institution, and costs associated with the renewal of
the headquarters office lease.

                                       15

         RESTRUCTURING RESERVE. In April 1999, the Company implemented a
restructuring of operations to reduce and economize its work force as part of an
overall plan to return to profitability. The restructuring charges of $900,000
resulted from approximately $843,000 of accrued severance and benefit costs
associated with a reduction-in-force of approximately 36 employees across all
functional areas of the Company, and approximately $57,000 of accrued facility
costs resulting from the consolidation of facilities and premature termination
of various office leases. The reduction-in-force and payment of severance will
occur over approximately a six-month period.

         INTEREST AND OTHER INCOME, NET. The Company had net interest expenses
of approximately $33,000 in the second quarter of 1999 compared to approximately
$24,000 in the same period in 1998. The quarter over quarter increase was
primarily the result of lower interest income due to less cash available for
overnight investments. For the first half of 1999, net interest expense was
approximately $173,000, compared to approximately $36,000 for the first half of
1998. The year over year increase in net interest expense is the combined result
of a $97,000 charge related to the fair value of warrants issued to the
Company's lending institution, approximately $26,000 lower interest income due
to less cash available for overnight investments, and higher interest costs
resulting from higher rates and loan balances during 1999.

         FOREIGN EXCHANGE GAIN OR LOSSES. The Company had no foreign exchange
gains for the first quarter of 1999, compared to a $6,000 foreign exchange loss
in the year earlier quarter. For the six months ended June 30, 1999, the Company
had no foreign exchange gains or losses, compared to a foreign exchange gain of
approximately $47,000 for the six months ended June 30, 1998.

         NET LOSS. For the second quarter of 1999, the Company had a net loss of
approximately $2.5 million, compared to a net loss of approximately $2.8 million
in second quarter of 1998. For the first half of 1999, the Company had a net
loss of approximately $3.8, equivalent to the net loss for the first half of
1998. The three and six month changes in net loss were the combined result of
all of the above factors.

LIQUIDITY AND CAPITAL RESOURCES

         At June 30, 1999, the Company had approximately $3.9 million of cash
and cash equivalents and net working capital of $8.6 million, compared to
approximately $2.5 million of cash and cash equivalents and net working capital
of $7.6 million at December 31, 1998. For the six months ended June 30, 1999 and
1998, total cash used by operations was approximately $713,000 and $3.6 million,
respectively. The cash used by operations was primarily due to continued net
losses from operations. The decrease in cash used in operating activities during
the first half of 1999, when compared to the same period in 1998, was primarily
the result of a decrease in accounts receivable of approximately $1.6 million in
1999 compared to an increase in accounts receivable of approximately $1.2
million for the first half of 1998. During the first half of 1999, the Company
used cash to pay-down the line of credit by approximately $1.7 million.

         In May 1999, the Company received net proceeds of approximately $4.0
million from a private placement of Series A Convertible Preferred Stock. In
April 1998, the Company received net proceeds of approximately $2.1 million
through a private placement of Common Stock.

         Capital acquisitions during the first half of 1999 were approximately
$121,000 compared to $666,000 in the first half of 1998. These acquisitions were
primarily equipment used for research and development purposes and computer and
test equipment.

         In November 1997, the Company negotiated a $3.0 million line of credit
agreement with a lending institution to be used for working capital. This
agreement provided for interest at a per annum rate equal to the lender's prime
rate plus 2%, subject to a minimum monthly interest based on 40% utilization of
$3.0 million. In August 1998, as a result of concerns about the deterioration of
aged international accounts receivable, the Company's lending institution
eliminated international receivables as qualified accounts receivable for
borrowing collateral. The lending institution also increased the interest rate
for outstanding loan amounts to prime plus 3 1/2% from prime plus 2%. In October

                                       15

1998, the lending institution reinstated a sub-line of credit up to an amount of
$600,000 for selected foreign accounts receivable. Borrowings under the line are
based on qualified domestic accounts receivable and are collateralized by the
Company's assets. At June 30, 1999, the Company had approximately $3.9 million
in cash and cash equivalents with approximately $428,000 outstanding of the
approximately $1.4 million available under the line of credit agreement. At
December 31, 1998, the Company had approximately $2.4 million of eligible
borrowing availability and approximately $2.2 million outstanding under the line
of credit. As of June 30, 1999, the Company's domestic accounts receivable have
generated adequate borrowing for operations, and the Company has not had to use
the foreign sub-line of credit.

         As a result of the combination of the net loss for the quarter and the
proceeds of the private placement, the Company's tangible net worth increased
from $9.9 million at March 31, 1999 to $11.6 million at June 30, 1999. The line
of credit agreement negotiated in November 1997 required the Company to maintain
a tangible net worth of at least $13.5 million measured at the end of each
month. Since October 31, 1998 the Company has been in violation of this
covenant. This covenant violation allows the Company's lending institution to
call for collection of the outstanding loan balance. On April 12, 1999 the
lending institution granted the Company a waiver of past covenant violations and
waived its right to call the line of credit for these covenant violations.
Concurrent with the April 1999 waiver of default, the lending institution
extended the line of credit agreement to May 31, 2001. The lending institution
amended the line of credit agreement to measure the Company's tangible net worth
on a quarterly basis effective January 1, 1999, and set the minimum tangible net
worth covenant at $9.8 million as of March 31, 1999 and $9.0 million for all
subsequent quarters. As of June 30, 1999, the Company was in compliance with the
new covenant, and management believes that this new covenant will be adequate
for the Company to operate under in the foreseeable future. However, there can
be no assurances that the Company will not violate the new covenant or that the
outstanding loan balance will not be called by the lending institution upon
violation of the new covenant.

         The success of the Company is dependent on its ability to generate
adequate cash for operations and capital needs. Its ability to generate adequate
cash for such needs is in part dependent on its success in increasing sales of
its products. The Company's plan is to increase revenues through sales of its
Network Exchange product line; however, due to market conditions and other
factors beyond its control, there can be no assurance the Company will be able
to adequately increase product sales. Therefore, the Company may have to
generate additional cash through the sale of assets including technologies or
the sale of debt or equity securities. Although the Company believes it has the
ability to generate additional cash through such sales, such sales may be
dilutive and there can be no assurances that adequate funds will be available or
available on terms that are reasonable or acceptable to the Company. If the
Company is unable to generate adequate cash, there could be a material and
adverse effect on the business and financial condition of the Company. The
Company has implemented cost control measures and is continually evaluating
expense levels to mitigate its liquidity risk.


YEAR 2000

         The Year 2000 presents concerns for business and consumer computing.
Aside from the well-known problems with the use of certain 2-digit date formats
as the year changes from 1999 to 2000, the Year 2000 is a special case leap
year, and dates such as 9/9/99 were used by certain organizations for special
functions. The problem exists for many kinds of software and hardware, including
mainframes, mini-computers, PCs, and embedded systems.

         Netrix Corp has divided the year 2000 task into three areas of concern,
Netrix Product, Netrix Suppliers, and Netrix Internal Systems. The Company's
core products have been reviewed, tested and if required, corrective measures
have been implemented to ensure no year 2000 issues. This task is complete with
information regarding the Netrix Products available via Internet access and
software release notes. NETRIX suppliers are being asked to respond to the year
2000 issue. This will be an ongoing process and is considered a low risk to the

                                       16

<PAGE>

Company. Netrix has audited its Internal Systems and corrective measures are
being taken to correct identified year 2000 issues.

         Internal Systems represent the largest area of concern for the Company.
The Internal Systems category has been further broken down into hardware and
software areas, business / operations applications, engineering applications,
Unix based technologies and PC based technologies. The Company has identified
all major hardware and software components that need to be assessed and has
performed an assessment of all hardware and software identified.

         The Company has updated a majority of hardware in use and is in the
process of converting all software applications that are known to have year 2000
issues. In August 1999, NETRIX successfully completed the Y2K software
conversion upgrade for the Company's primary business / operations application
for live production use in the third quarter of 1999.

         Vendors or other third parties that could affect the Company's
operations include suppliers of utility services, travel and hotel services,
office supply vendors, equipment and technology vendors, mail, telephone,
Internet and other communications services. Each of the Company's departmental
directors has been instructed to communicate with their major suppliers with
respect to such vendors' year 2000 compliance status. All of the Company's
departments have been directed to make arrangements with an alternative vendor
if it appears that the current vendor will not achieve compliance by the year
2000. There can be no guarantee, however, that the systems of the Company's
major vendors, including providers of public utilities, will be timely
converted, or that a failure to convert by another company or organization, or a
conversion that is incompatible with the Company's systems, would not have an
adverse effect on the Company.

         Although the Company anticipates that minimal business disruptions will
occur as a result of year 2000 issues, possible consequences include loss of
communications with members, inability to conduct marketing efforts and on-site
seminars as a result of travel and communications disruptions, delay in the
production and distribution of studies and reports, inability to conduct
research and surveys, and disruption of similar normal business activities. The
Company believes that the conversion and modification efforts by the Company and
its vendors will mitigate the risks associated with year 2000 issues. If,
however, the Company or its essential vendors do not complete the necessary
modifications or conversions in a timely manner or if such modifications or
conversions fail to achieve the proper results, the Company's operations may be
adversely effected.

         The Company does not intend to develop any contingency plans to address
possible failures by the Company or its vendors to the year 2000 compliant with
respect to information technology systems. The Company does not believe that
such contingency plans are required because it believes that the Company and its
information technology suppliers will be year 2000 compliant before January
2000. The Company currently does not have any contingency plans to address
possible failures by its vendors to be year 2000 compliant with respect to
non-information technology systems, but expects to develop such plans by
September 1999.

         While Year 2000 issues present a potential risk to the Company's
internal systems, distribution and supply chain, and facilities, the Company is
minimizing its risk with a concentrated effort. The Company is performing an
extensive assessment and is in the process of testing and remediating mission
critical components. The Company has already identified and resolved a majority
of these components, and expects that all components will be resolved by the
fourth quarter. Management currently believes that all critical systems will be
ready by January 1, 2000 and that the costs to address these issues will not
exceed the budgeted amounts. Management estimates the cost to address and
resolve Year 2000 issues will approximate $500,000, and these costs have been
included in the Company's operating plan for 1999.

PART II -- OTHER INFORMATION

         ITEM 1.  NOT APPLICABLE.

         ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS.

         During the period ended June 30, 1999, we raised funds through an
offering of convertible preferred stock. We also compensated certain persons for
services they provided to us by issuing warrants to them.

         We offered and sold 298,187 shares of Series A 8% convertible preferred
stock in a private offering exempt from registration under the Securities Act
pursuant to Section 4(2) of the Securities Act. We did not use an underwriter in
the offering, although we did compensate certain persons who introduced us to
investors, as described below. We sold the preferred stock at $13.75 per share,
which represented five times the price of our common stock at the time the
shares were issued. Each share of preferred stock is convertible into shares of
our common stock at a conversion price of $2.75 per share (representing five
shares of common stock for every share of preferred stock). We have filed a
registration statement related to the resale of the common stock underlying the
preferred stock, however, most of this common stock is subject to limitations on
transfer until May 2000. The resale limitations will be lifted prior to May 2000
as follows:

     o        if the average closing bid price for our stock price is at least
              $3.43 for 10 consecutive trading days, 25% of the common stock
              may be sold;
     o        if the average closing bid price for our stock price is at least
              $4.29 for 10 consecutive trading days, an additional 25% of the
              common stock may be sold;
     o        if the average closing bid price for our stock price is at least
              $5.36 for 10 consecutive trading days, an additional 25% of the
              common stock may be sold; and
     o        if the average closing bid price for our stock price is at least
              $6.71 for 10 consecutive trading days, all remaining shares will
              may be sold.

         In April 1999, in connection with obtaining an amendment and waiver of
certain covenants contained in our credit agreement, we issued to Coast Business
Credit, a division of Southern Pacific Bank, warrants to acquire 50,000 shares
of common stock. The warrants are exercisable at $2.00 per share, and are
exercisable until June 2004. In issuing these warrants, we relied upon the
exemption from registration under the Securities Act provided by Section 4(2) of
the Securities Act.

         In May 1999 we issued 25,000 warrants to Renwick Securities, Inc. as
compensation for financial consulting services they provided to us. 10,000 of
the warrants are exercisable at $3.00 per share, 7,500 are exercisable at $5.00
per share and 7,500 are exercisable at $7.00 per share. All of these warrants
expire on March 30, 2004. In issuing these warrants, we relied upon the
exemption from registration under the Securities Act provided by Section 4(2) of
the Securities Act.

         In June 1999, we issued warrants to a consultant who is providing
advice to us related to reducing costs associated with certain of our
operations. As consideration, we issued 7,500 warrants to the consultant,
exercisable through June 2004 at $3.00 per share. In issuing these warrants, we
relied upon the exemption from registration under the Securities Act provided by
Section 4(2) of the Securities Act.

         In connection with the offering of the Series A preferred stock, we
agreed to pay compensation to certain persons who introduced investors to us. We


                                       18

<PAGE>

offered these persons the right to receive payment either (1) in cash or (2) in
warrants to acquire common stock, and each of such persons requested payment in
warrants. Accordingly, in June 1999 we issued 17,818 warrants exercisable at
$3.50 per share and 32,000 warrants exercisable at $2.75 per share to these
persons. Each warrant expires in 2004. In issuing these warrants, we relied upon
the exemption from registration under the Securities Act provided by Section
4(2) of the Securities Act.

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

                        PURSUANT TO SECTION 151(G) OF THE
               GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

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

      The  undersigned DO HEREBY CERTIFY that the following  resolution was duly
adopted by the Board of Directors of Netrix Corporation,  a Delaware corporation
(the "Corporation"),  at a meeting duly convened and held, at which a quorum was
present and acting throughout:

      "RESOLVED,  that  pursuant  to the  authority  conferred  on the  Board of
   Directors of the Corporation (the "Board of Directors") by the  Corporation's
   Certificate of  Incorporation,  the issuance of a series of preferred  stock,
   $.05 par value per share, of the  Corporation  which shall consist of 290,925
   shares of  preferred  stock be, and the same hereby is,  authorized;  and the
   President and  Secretary or Assistant  Secretary of the  Corporation  be, and
   they  hereby  are,  authorized  and  directed  to  execute  and file with the
   Secretary of State of the State of Delaware the  Certificate of  Designations
   of  Preferred  Stock of the  Corporation  fixing  the  designations,  powers,
   preferences and rights of the shares of such series, and the  qualifications,
   limitations or restrictions thereof (in addition to the designations, powers,
   preferences and rights, and the  qualifications,  limitations or restrictions
   thereof,  set  forth  in  the  Certificate  of  Incorporation  which  may  be
   applicable to the Corporation's preferred stock), as follows:

      1. NUMBER OF SHARES;  DESIGNATION.  A total of 290,925 shares of preferred
   stock, par value $.05 per share, of the Corporation are hereby  designated as
   Series A 8%  Convertible  Preferred  Stock  (the  "Series").  The  number  of
   authorized  shares of the Series may be reduced by the Board of  Directors by
   the  filing  of a  certificate  pursuant  to the  provisions  of the  General
   Corporation  Law of the  State  of  Delaware  (the  "GCL")  stating  that the
   reduction has been so authorized.

      2. RANK.  The Series  shall,  with  respect to payment of  dividends,
   redemption payments and rights upon liquidation,  dissolution or winding
   up of the affairs of the Corporation, rank:

      (i)senior and prior to the Common Stock,  par value $.05 per share, of the
         Corporation  (the  "Common  Stock"),   and  any  additional  series  of
         preferred  stock  which may in the future be issued by the  Corporation

<PAGE>

         and are designated in the amendment to the Certificate of Incorporation
         or  the  certificate  of  designations   establishing  such  additional
         preferred  stock as  ranking  junior to the shares of the  Series.  Any
         shares of the  Corporation's  capital  stock  which  are  junior to the
         shares of the Series  with  respect to the  payment  of  dividends  are
         hereinafter  referred  to as "Junior  Dividend  Shares"  and any shares
         which  are  junior  to  the  shares  of  the  Series  with  respect  to
         redemption, payment and rights upon liquidation, dissolution or winding
         up of the affairs of the  Corporation  are  hereinafter  referred to as
         "Junior Liquidation Shares."

      (ii) PARRI PASSU with any additional  series of preferred  stock which may
         in the future be issued by the  Corporation  and are  designated in the
         amendment to the  Certificate of  Incorporation  or the  certificate of
         designations  establishing  such additional  preferred stock as ranking
         equal to the shares of the Series or which do not state they are Junior
         Dividend  Shares or Senior  Dividend  Shares (as  defined  below).  Any
         shares of the Corporation's capital stock which are equal to the shares
         of the Series with respect to the payment of dividends are  hereinafter
         referred to as "Parity  Dividend Shares" and any shares which are equal
         to the shares of the Series  with  respect to  redemption,  payment and
         rights upon  liquidation,  dissolution  or winding up of the affairs of
         the  Corporation  are  hereinafter  referred to as "Parity  Liquidation
         Shares."

      (iii) Senior to any additional  series of preferred stock which may in the
         future be issued by the Corporation and are designated in the amendment
         to the Certificate of  Incorporation or the certificate of designations
         establishing  such additional  preferred stock as ranking senior to the
         shares of the Series.  Any shares of the  Corporation's  capital  stock
         which  are  senior to the  shares of the  Series  with  respect  to the
         payment of dividends are  hereinafter  referred to as "Senior  Dividend
         Shares"  and any  shares  which are  senior to the shares of the Series
         with  respect  to  redemption,  payment  and rights  upon  liquidation,
         dissolution  or  winding  up of  the  affairs  of the  Corporation  are
         hereinafter referred to as "Senior Liquidation Shares."

   The  Corporation  may issue  additional  shares of capital  stock without the
   consent of the holders of the Series.

      3. DIVIDENDS. (a) The dividend rate on shares of the Series shall be $1.10
   per share  per  annum.  Dividends  on  shares  of the  Series  shall be fully
   cumulative, accruing, without interest, from the date of original issuance of
   the Series through the date of redemption or conversion thereof, and shall be
   payable in arrears, when, as and if declared by the Board of Directors out of
   funds legally available for the payment of dividends, on April 30 and October
   31 of each year, commencing October 31, 1999, except that if such date is not
   a business  day then the dividend  shall be payable on the first  immediately
   succeeding  business day (as used herein,  the term "business day" shall mean
   any day except a Saturday,  Sunday or day on which banking  institutions  are
   legally  authorized  to close in Herndon,  Virginia)  (each such period being
   hereinafter  referred to as a "Dividend Period").  Dividends shall be payable
   in cash or Common  Stock,  at the  discretion  of the  Company.  The means of

                                       2

<PAGE>

   payment (cash or Common  Stock) of each  dividend  shall be designated by the
   Board of  Directors  at the time it fixes  the  record  date for  determining
   holders of shares of the Series  entitled to receive such  dividend  payment.
   Each dividend  shall be paid to the holders of record of shares of the Series
   as they appear on the stock  register of the  Corporation on the record date,
   not less than 10 nor more than 60 days preceding the payment date thereof, as
   shall be fixed by the Board of  Directors.  If any dividend is  designated as
   being  payable  in  Common  Stock,  the  amount  of  Common  Stock  issued in
   satisfaction  of such dividend  shall be determined by dividing the amount of
   the dividend  payable with respect to each share of the Series by the Current
   Market  Price (as defined in Section 10) for the Common Stock as of the close
   of business on the business day the Board of Directors  fixes the record date
   for  determining  the holders  entitled to receive such  dividend.  Dividends
   payable for each Dividend  Period shall be computed on the basis of a 360-day
   year of twelve  30-day  months and rounded to the nearest cent. No fractional
   share of Common Stock shall be issued with  respect to any  dividend  paid in
   Common  Stock.  The  aggregate  number of shares  issuable  to each holder of
   shares of the Series will be calculated,  and in lieu of issuing a fractional
   share the Corporation  shall pay the cash value of such  fractional  share as
   determined  by  reference  to the Current  Market  Price used for purposes of
   calculating  the  number  of  shares  of  Common  Stock to be  issued in such
   dividend. Dividends on account of arrearages for any past Dividend Period may
   be declared and paid at any time,  without  reference to any regular dividend
   payment  date,  to  holders  of record on such date,  not  exceeding  45 days
   preceding the payment date thereof, as may be fixed by the Board of Directors
   of  the  Corporation.  Dividends  shall  accrue  regardless  of  whether  the
   Corporation has earnings,  whether there are funds legally available therefor
   and  whether  declared.  No  interest  shall be payable  with  respect to any
   dividend  payment  that may be in  arrears.  Holders  of Shares of the Series
   called for  redemption  between the close of  business on a dividend  payment
   record date and the close of business on the  corresponding  dividend payment
   date shall,  in lieu of receiving such dividend on the dividend  payment date
   fixed  therefor,  receive  such  dividend  payment  on  the  date  fixed  for
   redemption  together with all other accrued and unpaid  dividends to the date
   fixed for  redemption.  The  holders of shares of the Series  shall be not be
   entitled to any dividends other than the cash dividends  provided for in this
   paragraph 3.

      (b) No  dividends,  except as described in the next  succeeding  sentence,
   shall be  declared  or paid or set apart for  payment on any Parity  Dividend
   Shares  for  any  period  unless  full  cumulative  dividends  have  been  or
   contemporaneously are declared and paid or declared and set aside for payment
   for all accrued  dividends with respect to the Series through the most recent
   Dividend  Period ending on or prior to the date of payment,  or setting apart
   for  payment,  of such  dividends  on such  Parity  Dividend  Shares.  Unless
   dividends  accrued  and  payable  but  unpaid on shares of the Series and any
   Parity  Dividend Shares at the time  outstanding  have been paid in full, all
   dividends  declared  by the  Corporation  upon shares of the Series or Parity
   Dividend  Shares  shall be declared PRO RATA with respect to all such shares,
   so that the amounts of any dividends declared on shares of the Series and the
   Parity  Dividend  Shares shall in all cases bear to each other the same ratio
   that,  at the time of the  declaration,  all accrued but unpaid  dividends on
   shares of the Series and the other Parity Dividend Shares, respectively, bear
   to each other.

                                       3

      (c) If at any time the  Corporation  has  failed  to pay or set  apart for
   payment all accrued  dividends  on any shares of the Series  through the then
   most recent Dividend Period,  the Corporation shall not, and shall not permit
   any  corporation  or other entity  directly or  indirectly  controlled by the
   Corporation to:

        (i) declare  or pay or set  aside  for  payment  any  dividend  or other
            distribution  on or with  respect  to the  Junior  Dividend  Shares,
            whether in cash,  securities,  obligations or otherwise  (other than
            dividends or  distributions  paid in shares of capital  stock of the
            Corporation  ranking  junior to shares of the Series  both as to the
            payment of dividends and as to rights in liquidation, dissolution or
            winding up of the affairs of the Corporation  ("Junior  Stock"),  or
            options,  warrants or rights to subscribe for or purchase  shares of
            Junior Stock); or

       (ii) redeem,  purchase or  otherwise  acquire,  or pay into,  set apart
            money or make  available for a sinking or other  analogous  fund for
            the redemption,  purchase or other acquisition of, any shares of the
            Series  (unless  all of the shares of the  Series  are  concurrently
            redeemed),  Parity Dividend  Shares,  Parity  Liquidation  Shares or
            Shares of Junior Stock for any  consideration  (except by conversion
            into or exchange for Junior Stock),

   unless,  in each such  case,  all  dividends  accrued on shares of the Series
   through the most recent  Dividend  Period and on any Parity  Dividend  Shares
   have been or contemporaneously are declared and paid in full.

      (c) Any reference to  "distribution"  contained in this  paragraph 3 shall
   not be  deemed  to  include  any  distribution  made in  connection  with any
   liquidation,  dissolution or winding up of the Corporation, whether voluntary
   or involuntary.

      4.  LIQUIDATION.  (a) The  liquidation  value  per  share of shares of the
   Series, in case of the voluntary or involuntary  liquidation,  dissolution or
   winding-up of the affairs of the Corporation, shall be $13.75 per share, plus
   an amount  equal to the cash value of dividends  accrued and unpaid  thereon,
   whether or not  declared,  to the payment date (such  aggregate  amount being
   hereinafter referred to as the "Liquidation Amount").

      (b) In the event of any voluntary or involuntary liquidation,  dissolution
   or  winding-up  of the  Corporation,  the holders of shares of the Series (i)
   shall not be entitled to receive the liquidation  value of the shares held by
   them until the liquidation value of all Senior  Liquidation Shares shall have
   been paid in full and (ii) shall be entitled to receive the liquidation value
   of such  shares  held  by them in  preference  to and in  priority  over  any
   distributions upon the Junior Liquidation Shares. Upon payment in full of the
   liquidation  value to which the holders of shares of the Series are entitled,
   the  holders  of shares of the Series  will not be  entitled  to any  further
   participation in any distribution of assets by the Corporation. If the assets
   of the Corporation  are not sufficient to pay in full the  liquidation  value
   payable to the  holders of shares of the  Series  and the  liquidation  value
   payable to the holders of any Parity  Liquidation  Shares, the holders of all
   such shares shall share ratably in such  distribution of assets in accordance
   with the amounts that would be payable on the  distribution if the amounts to

                                       4

<PAGE>

   which  the  holders  of  shares  of the  Series  and the  holders  of  Parity
   Liquidation Shares are entitled were paid in full.

      (c) Neither a consolidation  or merger of the Corporation with or into any
   other entity,  nor a merger of any other entity with or into the Corporation,
   nor a sale or  transfer  of all or any part of the  Corporation's  assets for
   cash or  securities  or other  property  shall be  considered a  liquidation,
   dissolution  or  winding-up  of the  Corporation  within the  meaning of this
   paragraph 4.

      (d) Written  notice of any  liquidation,  dissolution or winding up of the
   Corporation,  stating the payment  date or dates when and the place or places
   where the amounts distributable in such circumstances shall be payable, shall
   be given by first class mail, postage prepaid, not less than 30 days prior to
   any payment  date stated  therein,  to the holders of record of shares of the
   Series at their respective addresses as the same shall appear on the books of
   the transfer agent with respect to the Series.

      5. OPTIONAL REDEMPTION. (a) Shares of the Series will be redeemable at the
   option of the Corporation,  in whole or in part, from and after the time that
   the Current  Market Price for the Common Stock for a period of 10 consecutive
   trading days equals or exceeds $6.00 per share.  The redemption price will be
   payable  in cash and  equal  $17.50,  together  with an  amount  equal to the
   dividends  accrued  and  unpaid  thereon,  whether  or not  declared,  to the
   redemption date. The aggregate payment to each holder of shares of the Series
   to be  redeemed  will be rounded to the  nearest  cent.  Notwithstanding  the
   foregoing,  if the date fixed for redemption occurs after a record date for a
   dividend and prior to the corresponding  payment date, such dividend shall be
   paid,  on the payment date and the amount  payable with respect to each share
   of the Series  redeemed shall not include the amount of the dividend to be so
   paid.

      (b) Not less than 30 nor more than 60 days prior to the date fixed for any
   redemption of shares of the Series  pursuant to this paragraph 5, a notice of
   redemption  shall be mailed by first class  mail,  postage  prepaid,  to each
   holder of shares of the Series to be redeemed at such  holder's  last address
   as it appears on the books of the transfer agent for the Series.  Such notice
   shall state:  (i) that the Corporation has elected to redeem all or a portion
   of the shares of the Series, as specified in such notice, (ii) the redemption
   price, (iii) the redemption date, (iv) that, unless the Corporation  defaults
   in the payment of the redemption  price,  all shares of the Series called for
   redemption  shall cease to accrue  dividends  after the  redemption  date and
   shall cease to be outstanding  after such date and (v) any other  information
   required by applicable  law to be included  therein and any other  procedures
   that a holder of shares of the  Series  must  follow to receive  payment  for
   their redeemed  shares.  Neither failure to mail such notice,  nor any defect
   therein or in the mailing thereof,  to any particular holder shall affect the
   sufficiency of the notice or the validity of the  proceedings  for redemption
   with  respect to any other  holder.  Any notice  mailed in the manner  herein
   provided  shall be  conclusively  presumed to have been duly given whether or
   not the holder  receives the notice.  On or after the redemption  date,  each
   holder of shares of the Series to be redeemed  shall  present  and  surrender
   such holder's  certificate or certificates for such shares to the Corporation
   at the place designated in the redemption notice and thereupon the redemption
   price of the shares shall be paid to or on the order of the person whose name

                                       5

<PAGE>

   appears on such  certificate or certificates  as the owner thereof,  and each
   surrendered  certificate shall be canceled.  In case less than all the shares
   represented by any such certificate are redeemed,  a new certificate shall be
   issued to the holder representing the unredeemed shares of the Series.

      (c) If a notice of redemption  has been given pursuant to this paragraph 5
   and if, on or before the date fixed for  redemption,  the funds necessary for
   such redemption  shall have been set aside by the  Corporation,  separate and
   apart from its other funds,  in trust for the PRO RATA benefit of the holders
   of the shares of the Series so called for redemption,  then,  notwithstanding
   that  any  certificates  for  such  shares  have  not  been  surrendered  for
   cancellation,  on the redemption  date dividends shall cease to accrue on the
   shares of the  Series to be  redeemed,  and at the close of  business  on the
   redemption  date the  holders of such shares  shall cease to be  stockholders
   with respect to those shares, shall have no interest in or claims against the
   Corporation  by virtue  thereof and shall have no voting or other rights with
   respect  thereto,  except the right to receive the moneys  payable  upon such
   redemption,  without interest thereon,  upon surrender (and  endorsement,  if
   required by the Corporation) of their certificates,  and the shares evidenced
   thereby shall no longer be outstanding.  Subject to applicable  escheat laws,
   any moneys so set aside by the  Corporation  and  unclaimed at the end of two
   years from the redemption date shall revert to the  Corporation,  after which
   reversion the holders of such shares so called for redemption shall look only
   to the  Corporation  for the payment of the  redemption  price.  Any interest
   accrued on funds so deposited shall be paid to the  Corporation  from time to
   time.

      (d) If a notice of redemption has been given pursuant to this paragraph 5,
   and any holder of shares of the Series shall,  prior to the close of business
   on the date fixed for  redemption,  give  written  notice to the  Corporation
   pursuant to paragraph 7 below of the  conversion  of any or all of the shares
   to be redeemed  held by the  holder,  then such  redemption  shall not become
   effective as to such shares to be converted and such conversion  shall become
   effective as provided in paragraph 7 below,  whereupon any funds deposited by
   the  Corporation,  or on its behalf,  with a payment agent or segregated  and
   held in trust by the  Corporation  for the  redemption  of such shares  shall
   (subject to any right of the holder of such  shares to receive  the  dividend
   payable  thereon as provided  in  paragraph  7 below)  immediately  upon such
   conversion  be returned to the  Corporation  or, if then held in trust by the
   Corporation, shall be discharged from the trust.

      (e) In every case of redemption of less than all of the outstanding shares
   of the Series  pursuant to this  paragraph 5, the shares to be redeemed shall
   be  selected  PRO  RATA or by lot or in such  other  manner  as the  Board of
   Directors may  determine,  as may be prescribed by resolution of the Board of
   Directors  of the  Corporation,  provided  that only  whole  shares  shall be
   selected for redemption. Notwithstanding the foregoing, the Corporation shall
   not redeem any of the shares of the Series at any time outstanding  until all
   dividends  accrued  and  in  arrears  upon  all  shares  of the  Series  then
   outstanding shall have been paid for all past dividend periods.

      6. MANDATORY  REDEMPTION.  The shares of the  Series are not  subject
   to mandatory redemption or sinking fund requirements.

                                       6

      7.  CONVERSION.  (a)  Holders of shares of the Series will have the right,
   exercisable  at any time prior to  redemption of such shares (as described in
   paragraph  5), to convert  shares of the Series into  shares of Common  Stock
   (calculated as to each  conversion to the nearest  1/100th of a share) at the
   conversion  price of $2.75,  subject to  adjustment  as described  below (the
   "Conversion  Price").  The  number of shares of Common  Stock into which each
   share of the Series  shall be  convertible  shall be  determined  by dividing
   $13.75,   subject  to  proportional   adjustment  to  reflect  any  split  or
   consolidation of the Common Stock or any dividend payable on the Common Stock
   in  additional  shares of Common  Stock  (the  "Conversion  Amount"),  by the
   Conversion  Price then in effect.  In the case of shares of the Series called
   for redemption, conversion rights will expire at the close of business on the
   business day next preceding the redemption date. Except as expressly provided
   herein,  no payment or adjustment for accrued  dividends on the shares of the
   Series is to be made on  conversion,  but  holders of record of shares of the
   Series on a record  date fixed for the  payment of a dividend  on such shares
   shall be entitled to receive the dividend  notwithstanding  the conversion of
   the shares prior to the dividend  payment date. A share of the Series may not
   be converted in part.

      (b) In order to exercise the conversion right, the holder of each share of
   the Series to be converted shall surrender the certificate  representing such
   share,  duly  endorsed  or assigned to the  Corporation  or in blank,  at the
   office of the Corporation in Herndon,  Virginia (or such other address as the
   Corporation  may designate) and shall give written notice to the  Corporation
   in the form set forth on the reverse of the stock certificates for the shares
   of the Series that such holder  elects to convert the shares  represented  by
   such certificate or a portion thereof.  Such notice shall also state the name
   or names (with  address) in which the  certificate  or  certificates  for the
   shares of Common Stock which shall be issuable upon such conversion  shall be
   issued,  and shall be accompanied by funds in an amount sufficient to pay any
   transfer or similar tax required by the  provisions of paragraph  7(e) below.
   Each share  surrendered for conversion  shall,  unless the shares issuable on
   conversion  are to be issued in the same name as the name in which such share
   of the  Series is  registered,  be duly  endorsed  by, or be  accompanied  by
   instruments of transfer (in each case, in form reasonably satisfactory to the
   Corporation),  duly executed by the holder or such  holder's duly  authorized
   attorney-in-fact.

      (c) As promptly as  practicable  after the surrender of  certificates  for
   shares of the Series for conversion and the receipt of such notice and funds,
   if any, as aforesaid,  the Corporation  shall issue and shall deliver to such
   holder,  or on such holder's written order, a certificate or certificates for
   the number of shares of Common Stock  issuable  upon the  conversion  of such
   shares of the Series in accordance  with the  provisions of this paragraph 7,
   and a check or cash in respect  of any  fractional  interest  in respect of a
   share of Common Stock arising upon such conversion,  as provided in paragraph
   7(d) below. Each conversion with respect to any shares of the Series shall be
   deemed to have been  effected  immediately  prior to the close of business on
   the date on which the  certificates  for shares of the Series shall have been
   surrendered  (accompanied  by the funds,  if any,  required by paragraph 7(e)
   below) and such notice and  assignment,  if any,  shall have been received by
   the Corporation as aforesaid,  and the person or persons  entitled to receive
   the  Common  Stock  issuable  upon such  conversion  shall be deemed  for all
   purposes to be the record  holder or holders of such  Common  Stock upon that
   date.

                                       7

<PAGE>


      (d) No fractional shares of Common Stock or scrip representing  fractional
   shares shall be issued upon conversion of shares of the Series.  If more than
   one share of the Series shall be  surrendered  for  conversion at one time by
   the same  holder,  the number of full shares of Common  Stock  issuable  upon
   conversion  thereof shall be computed on the basis of the aggregate number of
   shares of the  Series so  surrendered.  Instead  of any  fractional  share of
   Common Stock otherwise  issuable upon conversion of any shares of the Series,
   the Corporation shall pay a cash adjustment in respect to such fraction in an
   amount equal to the same  fraction of the Current  Market Price of the Common
   Stock at the close of business on the day of conversion.

      (e) If a holder converts shares of the Series,  the Corporation  shall pay
   any and all  documentary,  stamp or similar  issue or transfer tax payable in
   respect  of the issue or  delivery  of the shares of the Series (or any other
   securities  issued on account thereof  pursuant  hereto) or Common Stock upon
   the conversion;  PROVIDED,  HOWEVER, the Corporation shall not be required to
   pay any such tax that may be payable  because any such shares are issued in a
   name other than the name of the holder.

      (f) The  Corporation  shall  reserve out of its  authorized  but  unissued
   Common Stock or its Common Stock held in treasury sufficient shares of Common
   Stock to  permit  the  conversion  of all of the  outstanding  shares  of the
   Series.  The Corporation shall from time to time, in accordance with the GCL,
   increase  the  authorized  amount  of its  Common  Stock  if at any  time the
   authorized  amount  of its  Common  Stock  remaining  unissued  shall  not be
   sufficient  to permit the  conversion of all shares of the Series at the time
   outstanding.  If any  shares of Common  Stock  required  to be  reserved  for
   issuance  upon  conversion  of  shares  of  the  Series   hereunder   require
   registration with or approval of any governmental authority under any federal
   or state law before the shares may be issued upon conversion, the Corporation
   shall in good faith and as  expeditiously  as possible  endeavor to cause the
   shares to be so registered or approved.  All shares of Common Stock delivered
   upon  conversion  of the shares of the Series will,  upon  delivery,  be duly
   authorized and validly issued,  fully paid and  nonassessable,  free from all
   taxes, liens and charges with respect to the issue thereof.

      (g) The Conversion  Price shall be subject to adjustment from time to time
   as follows:

        (i) In the event that the  Corporation  shall (A) pay a dividend or make
            a  distribution,  in shares of Common Stock, on any class of Capital
            Stock of the Corporation or any subsidiary  which is not directly or
            indirectly  wholly owned by the Corporation,  (B) split or subdivide
            its outstanding  Common Stock into a greater number of shares or (C)
            combine  its  outstanding  Common  Stock  into a  smaller  number of
            shares,  then in each  such  case the  Conversion  Price  in  effect
            immediately  prior  thereto  shall be adjusted so that the holder of
            each share of the Series thereafter surrendered for conversion shall
            be  entitled  to receive  the number of shares of Common  Stock that
            such holder would have owned or have been  entitled to receive after
            the occurrence of any of the events  described  above had such share
            of the Series been converted  immediately prior to the occurrence of
            such event.  An adjustment  made pursuant to this paragraph  7(g)(i)
            shall become  effective  immediately  after the close of business on

                                       8

<PAGE>

            the record date in the case of a dividend or distribution (except as
            provided  in  paragraph  7(k)  below)  and  shall  become  effective
            immediately after the close of business on the effective date in the
            case of such subdivision,  split or combination, as the case may be.
            Any shares of Common Stock  issuable in payment of a dividend  shall
            be  deemed  to have been  issued  immediately  prior to the close of
            business  on the  record  date for such  dividend  for  purposes  of
            calculating  the number of outstanding  shares of Common Stock under
            clauses (ii) and (iii) below.

       (ii) In  the  event  that  the  Corporation  shall  commit  to  issue  or
            distribute  Common  Stock  or issue  rights,  warrants,  options  or
            convertible or exchangeable  securities entitling the holder thereof
            to subscribe  for or  purchase,  convert into or exchange for Common
            Stock,  in any such case at a price per share less than the  Current
            Market  Price  per  share  on the  earliest  of  (i)  the  date  the
            Corporation  shall enter into a firm  contract for such  issuance or
            distribution,   (ii)  the  record  date  for  the  determination  of
            stockholders entitled to receive any such rights, warrants,  options
            or convertible or exchangeable securities,  if applicable,  or (iii)
            the date of actual issuance or distribution of any such Common Stock
            or  rights,   warrants,   options  or  convertible  or  exchangeable
            securities  (provided  that the  issuance  of Common  Stock upon the
            exercise of rights, warrants, options or convertible or exchangeable
            securities  will not cause an adjustment in the Conversion  Price if
            no such adjustment  would have been required at the time such right,
            warrant, option or convertible or exchangeable security was issued),
            then  the  Conversion  Price  in  effect  immediately  prior to such
            earliest date shall be adjusted so that the  Conversion  Price shall
            equal the price  determined by multiplying  the Conversion  Price in
            effect immediately prior to such earliest date by the fraction:

            (x)whose  numerator  shall be the  number of shares of Common  Stock
               outstanding  on such  date plus the  number  of shares  which the
               aggregate offering price of the total number of shares so offered
               would  purchase at such Current  Market Price (such amount,  with
               respect to any such rights,  warrants,  options or convertible or
               exchangeable  securities,  determined  by  multiplying  the total
               number of shares  subject  thereto by the exercise  price of such
               rights,   warrants,   options  or  convertible  or   exchangeable
               securities  and  dividing  the product so obtained by the Current
               Market Price), and

            (y)whose  denominator  shall be the number of shares of Common Stock
               outstanding on such date plus the number of additional  shares of
               Common  Stock to be  issued or  distributed  or  receivable  upon
               exercise of any such right,  warrant,  option or  convertible  or
               exchangeable security.

            Such adjustment shall be made successively  whenever any such Common
            Stock,  rights,  warrants,  options or convertible  or  exchangeable
            securities are issued or  distributed.  In  determining  whether any

                                       9

<PAGE>

            rights,  warrants or options entitle the holders to subscribe for or
            purchase  shares of Common  Stock at less than such  Current  Market
            Price, and in determining the aggregate  offering price of shares of
            Common  Stock so issued or  distributed,  there  shall be taken into
            account  any  consideration  received  by the  Corporation  for such
            Common  Stock,   rights,   warrants,   options,  or  convertible  or
            exchangeable securities,  the value of such consideration,  if other
            than  cash,  to be  determined  by the  Board  of  Directors,  whose
            determination  shall be  conclusive  and  described in a certificate
            filed with the records of corporate  proceedings of the Corporation.
            If  any  right,  warrant,  option  or  convertible  or  exchangeable
            security to purchase or acquire Common Stock,  the issuance of which
            resulted in an adjustment in the  Conversion  Price pursuant to this
            subsection (b) shall expire and shall not have been  exercised,  the
            Conversion   Price  shall   immediately   upon  such  expiration  be
            recomputed to the  Conversion  Price which would have been in effect
            had the adjustment of the Conversion Price made upon the issuance of
            such right, warrant,  option or convertible or exchangeable security
            been made on the basis of  offering  for  subscription,  purchase or
            issuance,  as the case may be,  only of that  number  of  shares  of
            Common Stock actually  purchased or issued upon the actual  exercise
            of such  right,  warrant,  option  or  convertible  or  exchangeable
            securities.

      (iii) No  adjustment in  the  Conversion  Price shall  be required  unless
            the adjustment  would require an increase or decrease of at least 1%
            in the Conversion Price then in effect; PROVIDED,  HOWEVER, that any
            adjustments  that  by  reason  of  this  paragraph  7(g)(i)  are not
            required to be made shall be carried  forward and taken into account
            in any subsequent adjustment.  All calculations under this paragraph
            7(g)(i)  shall be made to the nearest  cent or nearest  1/100th of a
            share.

      (iv)  Notwithstanding  anything  to  the  contrary  set  forth   in   this
            paragraph 7(g), no adjustment  shall be made to the Conversion Price
            upon (A) the  issuance  of shares of Common  Stock  pursuant  to any
            compensation or incentive plan for officers, directors, employees or
            consultants of the  Corporation  which plan has been approved by the
            Compensation  Committee of the Board of Directors (or if there is no
            such committee  then serving,  by the majority vote of the Directors
            then serving who are not employees or officers of the Corporation, a
            5% or greater stockholder of the Corporation or an officer, employee
            or Affiliate or Associate  (as defined in paragraph 10 below) of any
            such 5% or  greater  stockholder)  and,  if  required  by  law,  the
            requisite vote of the  stockholders of the  Corporation  (unless the
            exercise  price  thereof is changed after the date hereof other than
            solely by operation of the  anti-dilution  provisions  thereof or by
            the  Compensation  Committee  of  the  Board  of  Directors  or,  if
            applicable,  the Board of  Directors  and, if  required by law,  the
            stockholders  of the  Corporation as provided in this clause (A)) or
            (B) the issuance of Common Stock upon the  conversion or exercise of

            after  April  22,  1999  (other  than  solely  by  operation  of the
            anti-dilution provisions thereof).

        (v) The  Corporation  from time to time may reduce the Conversion  Price
            by any amount for any period of time in the  discretion of the Board
            of Directors. A voluntary reduction of the Conversion Price does not
            change  or adjust  the  conversion  price  otherwise  in effect  for
            purposes of this paragraph 7(g).

      (vii) In  the event that, at  any  time as a result of an adjustment  made
            pursuant to paragraph 7(g)(i) through 7(g)(iii) above, the holder of
            any share of the Series thereafter  surrendered for conversion shall
            become entitled to receive any shares of the Corporation  other than
            shares of the  Common  Stock,  thereafter  the  number of such other
            shares so  receivable  upon  conversion  of any share of the  Series
            shall be subject to adjustment  from time to time in a manner and on
            terms as nearly  equivalent as practicable  to the  provisions  with
            respect to the Common Stock contained in paragraphs  7(g)(i) through
            7(g)(vi) above, and the other provisions of this paragraph 7(g)(vii)
            with  respect to the Common  Stock  shall apply on like terms to any
            such other shares.

      (h) In case of any  reclassification  of the Common Stock (other than in a
   transaction to which paragraph  7(g)(i)  applies),  any  consolidation of the
   Corporation  with, or merger of the Corporation  into, any other entity,  any
   merger of another entity into the Corporation  (other than a merger that does
   not result in any reclassification,  conversion,  exchange or cancellation of
   outstanding shares of Common Stock of the Corporation),  any sale or transfer
   of  all  or  substantially  all  of the  assets  of  the  Corporation  or any
   compulsory share exchange,  pursuant to which share exchange the Common Stock
   is  converted  into other  securities,  cash or other  property,  then lawful
   provision shall be made as part of the terms of such transaction  whereby the
   holder of each  share of the  Series  then  outstanding  shall have the right
   thereafter,  during the period  such share shall be  convertible,  to convert
   such  share  only  into the kind and  amount  of  securities,  cash and other
   property receivable upon the reclassification,  consolidation,  merger, sale,
   transfer  or share  exchange  by a holder  of the  number of shares of Common
   Stock of the  Corporation  into which a share of the  Series  might have been
   converted immediately prior to the reclassification,  consolidation,  merger,
   sale,  transfer or share  exchange  assuming that such holder of Common Stock
   failed to exercise  rights of  election,  if any, as to the kind or amount of
   securities,  cash or other  property  receivable  upon  consummation  of such
   transaction  subject  to  adjustment  as  provided  in  paragraph  7(g) above
   following the date of consummation of such transaction. As a condition to any
   such  transaction,  the Corporation or the person formed by the consolidation
   or resulting  from the merger or which acquires such assets or which acquires
   the  Corporation's  shares,  as the case may be, shall make provisions in its
   certificate or articles of  incorporation  or other  constituent  document to
   establish such right.  The certificate or articles of  incorporation or other
   constituent   document  shall  provide  for  adjustments  which,  for  events
   subsequent  to  the  effective  date  of  the   certificate  or  articles  of
   incorporation or other constituent document, shall be as nearly equivalent as
   may be practicable to the  adjustments  provided for in this paragraph 7. The
   provisions  of this  paragraph  7(h)  shall  similarly  apply  to  successive

                                       11

<PAGE>

   reclassifications,   consolidations,   mergers,  sales,  transfers  or  share
   exchanges.

      (i)   If:

        (i) the  Corporation shall  take  any  action  which  would  require  an
            adjustment in the  Conversion  Price  pursuant to Section 7(g);
            or

       (ii) the Corporation  shall authorize  the granting to the holders of its
            Common Stock  generally  of rights or warrants to  subscribe  for or
            purchase any shares of any class or any other rights or warrants; or

      (iii) there shall be  any reclassification  or  change of the Common Stock
            (other than a subdivision or combination of its  outstanding  Common
            Stock or a change  in par  value)  or any  consolidation,  merger or
            statutory share exchange to which the Corporation is a party and for
            which approval of any  stockholders  of the Corporation is required,
            or the sale or transfer of all or substantially all of the assets of
            the Corporation; or

      (iv)  there   shall  be   a    voluntary   or   involuntary   dissolution,
            liquidation or winding up of the Corporation;

   then, the Corporation shall cause to be filed with the transfer agent for the
   Series and shall cause to be mailed to the holders of shares of the Series at
   their  addresses as shown on the books of the transfer  agent for the Series,
   as promptly as possible,  but at least 30 days prior to the  applicable  date
   hereinafter  specified, a notice stating (A) the date on which a record is to
   be taken for the purpose of such dividend, distribution or granting of rights
   or  warrants,  or, if a record  is not to be taken,  the date as of which the
   holders  of  Common  Stock  of  record  to  be  entitled  to  such  dividend,
   distribution  or rights or warrants are to be  determined  or (B) the date on
   which such reclassification,  change, consolidation,  merger, statutory share
   exchange, sale, transfer, dissolution,  liquidation or winding up is expected
   to become  effective or occur,  and the date as of which it is expected  that
   holders of Common Stock of record shall be entitled to exchange  their shares
   of Common  Stock  for  securities  or other  property  deliverable  upon such
   reclassification,  change,  consolidation,  merger, statutory share exchange,
   sale, transfer, dissolution,  liquidation or winding up. Failure to give such
   notice or any defect therein shall not affect the legality or validity of the
   proceedings described in this paragraph 7(i).

      (j)  Whenever the  Conversion  Price is adjusted as herein  provided,  the
   Corporation  shall  promptly  file with the  transfer  agent for the Series a
   certificate  of an officer of the  Corporation  setting forth the  Conversion
   Price after the adjustment  and setting forth a brief  statement of the facts
   requiring such adjustment and a computation  thereof.  The Corporation  shall
   promptly cause a notice of the adjusted Conversion Price to be mailed to each
   registered holder of shares of the Series.

      (k) In any case in which paragraph 7(g) provides that an adjustment  shall
   become  effective  immediately  after a record date for an event and the date
   fixed for such adjustment pursuant to paragraph 7(g) occurs after such record
   date but before the occurrence of such event, the Corporation may defer until

                                       12

<PAGE>

   the actual  occurrence  of such event (i) issuing to the holder of any shares
   of the Series  converted  after such record date and before the occurrence of
   such  event  the  additional  shares  of  Common  Stock  issuable  upon  such
   conversion by reason of the adjustment  required by such event over and above
   the Common Stock issuable upon such  conversion  before giving effect to such
   adjustment  and (ii)  paying to such holder any amount in cash in lieu of any
   fraction pursuant to paragraph 7(d).

      (l) In case the  Corporation  shall take any action  affecting  the Common
   Stock, other than actions described in this paragraph 7, which in the opinion
   of the Board of Directors would  materially  adversely  affect the conversion
   right of the holders of the shares of the Series, the Conversion Price may be
   adjusted, to the extent permitted by law, in such manner, if any, and at such
   time,  as the  Board  of  Directors  may  determine  to be  equitable  in the
   circumstances;  PROVIDED,  HOWEVER,  that in no  event  shall  the  Board  of
   Directors be required to take any such action.

      (m) The  Corporation  will  endeavor  to list the  shares of Common  Stock
   required to be delivered  upon  conversion of shares of the Series,  prior to
   delivery,  upon each national securities exchange, the Nasdaq Stock Market or
   any similar system of automated  dissemination of securities  prices, if any,
   upon which the Common Stock is listed at the time of delivery.

      8.  STATUS  OF  SHARES.  All  shares  of the  Series  that are at any time
   redeemed or converted  pursuant to  paragraph 5 above,  and all shares of the
   Series that are otherwise  reacquired  by the  Corporation  and  subsequently
   canceled by the Board of Directors,  shall have the status of authorized  but
   unissued shares of preferred stock, without designation as to series, subject
   to  reissuance  by the Board of  Directors as shares of any one or more other
   series.

      9. VOTING RIGHTS.  Except as otherwise  required by law, holders of shares
   of the Series shall have no vote with respect to any matter  submitted to the
   stockholders of the  Corporation for vote or consent.  In connection with any
   right to vote or give consent  provided by law,  each holder of shares of the
   Series will have one vote for each share held.

Preferred Stock. The minimum subscription is $100,000,  subject to waiver to the

(the "Registration  Rights Agreement")  providing for registration of the Common
Stock  issuable  upon  conversion  of the  Preferred  Stock and any Common Stock
issuable  as a  dividend  on the  Preferred  Stock.  The  designations,  powers,

limitations  and  restrictions  of  the  Preferred  Stock  are  set  forth  in a

the Company (the "Certificate of Designations"). The Certificate of Designations
will be filed with the  Secretary of State of the State of Delaware  immediately

            Subscriptions  shall be paid by check or wire transfer and deposited
in an escrow account maintained by Republic National Bank of New York, New York,

(as  defined  in Section  1(c)).  If your  subscription  is not  accepted,  your
subscription  payment  will be  immediately  returned  to you.  At the  time the
Company accepts  subscriptions,  certificates  representing  the Preferred Stock

Coast Warrant No. 1

                                     WARRANT

                           To Purchase Common Stock of

                               NETRIX CORPORATION

                             Expiring June ___, 2004

      This is to certify that, for value received, COAST BUSINESS CREDIT, a
division of Southern Pacific Bank ("Coast"), or registered assigns, is entitled
to purchase from Netrix Corporation, a Delaware corporation (the "Company"),
50,000 duly authorized, validly issued, fully paid and nonassessable shares of
Common Stock of the Company (the "Warrant Shares"), at the initial purchase
price per share of $2.00, as may be adjusted from time to time in the manner
hereinafter provided ("Current Warrant Price"), exercisable at any time and from
time to time during the period commencing on the date hereof and ending on June
___, 2004 (the "Exercise Period"), all further subject to the terms, conditions
and adjustments herein set forth. This Warrant may be assigned by the holder
subject to SECTION 3 below.

      This Warrant is issued in connection with a Loan and Security Agreement,
dated as of November 18, 1997 by and between the Company and Coast and any and
all amendments, replacements, supplements and modifications thereto
(collectively, the "Credit Agreement"). Certain terms used in this Warrant are
defined in Section 5 hereof. Capitalized terms used herein and not otherwise
defined herein shall have the meaning assigned thereto in the Credit Agreement.

SECTION 1.  EXERCISE OF WARRANTS.

SEC 1.1     CASH EXERCISE. This Warrant may be exercised by the Warrantholder by
            (i) the surrender of this Warrant to the Company at the Warrant
            Office described in Section 2.1 with a duly executed Exercise Form
            specifying the number of Warrant Shares to be purchased, during
            normal business hours on any Business Day during the Exercise Period
            and (ii) the delivery of payment to the Company, for the account of
            the Company, by cash, wire transfer of immediately available funds
            to a bank account specified by the Company, or by certified or bank
            cashier's check, of the Current Warrant Price for the number of
            Warrant Shares specified in the Exercise Form in lawful money of the
            United States of America. The Company agrees that such Warrant
            Shares shall be deemed to be issued to the Warrantholder as the



<PAGE>

            record holder of such Warrant Shares as of the close of business on
            the date on which this Warrant has been surrendered and payment has
            been made for such Warrant Shares in accordance with this Agreement.
            A stock certificate or certificates for the Warrant Shares specified
            in the Exercise Form shall be delivered to the Warrantholder as
            promptly as practicable, and in any event within seven (7) Business
            Days, thereafter. The stock certificate(s) so delivered shall be in
            any such denominations as may be reasonably specified by the
            Warrantholder in the Exercise Form.

SEC 1.2     NET ISSUE EXERCISE. In lieu of exercise pursuant to Section
            1.1, this Warrant may be exercised by the Warrantholder by the
            surrender of this Warrant to the Company, with a duly executed
            Exercise Form marked to reflect net issue exercise and specifying
            the number of Warrant Shares to be purchased, during normal business
            hours on any Business Day during the Exercise Period. The Company
            agrees that such Warrant Shares shall be deemed to be issued to the
            Warrantholder as the record holder of such Warrant Shares as of the
            close of business on the date on which this Warrant shall have been
            surrendered. Upon such exercise, the Warrantholder shall be entitled
            to receive a number shares equal to the value of this Warrant (or
            the portion thereof being canceled) computed as of the date of
            surrender hereof to the Company using the following formula:

            X =      Y(A-B)
                     ------
                       A

      Where:

            X    = the number of shares of Common Stock to be issued to
                 Warrantholder under this SECTION 1.2;
            Y    = the number of shares of Common Stock otherwise purchasable
                 under this Warrant (at the date of such calculation);
            A    = the Current Market Price of shares of Common Stock to be
                 issued to the Warrantholder (at the date of such
                 calculation);
            B  =  the Current Warrant Price

SEC 1.3     CURRENT MARKET PRICE. For purposes of Section 1.2, current
            market price of one share of the Company's Common Stock (the
            "Current Market Price") shall mean (per share of Common Stock at any
            date): the per share fair market value of the Common Stock (i)
            determined by the average of the daily "market prices" over a period
            of 10 consecutive Business Days before such date or (ii) if and so
            long as there is no exchange or over-the-counter market for the
            Common Stock of the Company, the price per share which the Company
            could obtain from a willing buyer for the shares sold by the Company
            from authorized but unissued shares, as such price shall be
            determined in good faith by the Board of Directors of the Company
            and the Warrantholder, PROVIDED, HOWEVER, if the Company and the
            Warrantholder can not agree on a value, the Company and the
            holder(s) of the majority of the Warrants shall retain an
            independent investment banking firm to determine the per share fair
            market value of the Common Stock, with the expense of such firm to


                                      -2-
<PAGE>

            be shared equally by the Company and the Warrantholder(s). The
            market price referred to in clause (i) above for each such Business
            Day shall be: (A) the last sale price on such day on the principal
            securities exchange on which the Common Stock is then listed or
            admitted to trading (or, if no sale takes place on such day on any
            such exchange, the average of the closing bid and asked prices on
            such day as officially quoted on any such exchange), or (B) if the
            Common Stock is not then listed or admitted on any stock exchange,
            the market price for each such business day shall be the last sale
            price on such day (or, if no sale takes place on such day, the
            average of the closing bid and asked prices on such day in the
            over-the-counter market), in either case as reported through NASDAQ,
            (or, if such prices are not at the time so reported, as furnished by
            any member of the National Association of Securities Dealers, Inc.
            selected by the Company).

SEC 1.4     WARRANT SHARES TO BE FULLY PAID AND NONASSESSABLE. All shares
            of Common Stock issued upon the exercise of this Warrant shall be
            validly issued, fully paid and nonassessable and, if the Common
            Stock is then listed on a securities exchange, shall be duly listed
            thereon.

SEC 1.5     PARTIAL EXERCISE; FRACTIONAL SHARES. If this Warrant shall
            have been exercised only in part, the Company shall, at the time of
            delivery of the stock certificate(s), deliver to the Warrantholder a
            new Warrant evidencing the rights to purchase the remaining Warrant
            Shares, which new Warrant shall in all other respects be identical
            with this Warrant. The Company shall not be required upon any
            exercise of this Warrant to issue a certificate representing any
            fraction of a share of Common Stock, but, in lieu thereof, shall pay
            to the holder of this Warrant cash in an amount equal to a
            corresponding fraction (calculated to the nearest 1/100 of a share)
            of the Current Market Price of one share of Common Stock as of the
            date of receipt by the Company of notice of exercise of this
            Warrant.

SEC 1.6     LEGEND ON WARRANT SHARES. Each certificate for Warrant Shares
            initially issued upon exercise of this Warrant, unless at the time
            of exercise such Warrant Shares are registered under the Act, shall
            bear the following legend (and any additional legend required by any
            securities exchange upon which such Warrant Shares may, at the time
            of such exercise, be listed) on the face thereof:

            "The securities represented by this certificate have not been
            registered under the Securities Act of 1933, as amended, or the laws
            of any state."

            Any certificate issued at any time in exchange or substitution for
            any certificate bearing such legend (except a new certificate issued
            upon completion of (i) a public distribution pursuant to a
            registration statement or (ii) an exempt sale pursuant to Rule 144
            or Rule 144A under the Act of the securities represented thereby)
            shall also bear such legend unless, in the opinion of Orrick,
            Herrington & Sutcliffe LLP or such other counsel for the holder
            thereof as shall be reasonably acceptable to the Company, the
            securities represented thereby need no longer be subject to the
            restrictions contained in said Section 3. The provisions of said
            Section 3 shall be binding upon all subsequent holders of this
            Warrant.

SEC 1.7      ACKNOWLEDGMENT OF CONTINUING OBLIGATION. The Company will, at the
            time of any exercise of this Warrant in whole or in part, upon
            request of the holder hereof, acknowledge in writing its then
            continuing obligation to such holder in respect of any rights
            pursuant to this Warrant (including, without limitation, any
            right to registration, if any, of the shares of Common Stock
            issued upon such exercise) to which such holder shall continue to
            be entitled after such exercise in accordance with this Warrant;
            PROVIDED, HOWEVER, that the failure of such holder to make any
            such request shall not affect the continuing obligation of the
            Company to such holder in respect of such rights.

SECTION 2.  WARRANT OFFICE; TRANSFER, DIVISION OR COMBINATION OF WARRANTS.

SEC. 2.1    WARRANT OFFICE. The Company shall maintain an office for certain
            purposes specified herein (the "Warrant Office"), which office shall
            initially be the Company's office at 13595 Dulles Technology Drive,
            Herndon, Virginia 22071, and may subsequently be such other office
            of the Company or of any transfer agent of the Common Stock in the
            continental United States as to which written notice has previously
            been given to all of the Warrantholders.

SEC. 2.2    OWNERSHIP OF WARRANT. The Company may deem and treat the
            person in whose name this Warrant is registered as the holder and
            owner hereof (notwithstanding any notations of ownership or writing
            hereon made by anyone other than the Company) for all purposes and
            shall not be affected by any notice to the contrary, until
            presentation of this Warrant for registration of transfer as
            provided in this Section 2.

SEC. 2.3    TRANSFER OF WARRANTS. The Company agrees to maintain at the
            Warrant Office books for the registration and registration of
            transfer of the Warrants, and, subject to the provisions of Section
            3 hereof, this Warrant and all rights hereunder are transferable, in
            whole or in part, on said books at said office, upon surrender of
            this Warrant at said office, together with a written assignment of
            this Warrant duly executed by the holder hereof or his duly
            authorized agent or attorney and funds sufficient to pay any
            transfer taxes payable upon the making of such transfer. Upon such
            surrender and payment, the Company shall execute and deliver a new
            Warrant or Warrants in the name of the assignee or assignees and in
            the denominations specified in such instrument of assignment, and
            this Warrant shall promptly be cancelled. A Warrant may be exercised
            by a new holder for the purchase of shares of Common Stock without
            having a new Warrant issued.

SEC. 2.4    DIVISION OR COMBINATION OF WARRANTS. This Warrant may be
            divided or combined with other Warrants upon presentation hereof and
            of any Warrant or Warrants with which this Warrant is to be combined
            at the Warrant Office, together with a written notice specifying the
            names and denominations in which new Warrants are to be issued,
            signed by the holders hereof and thereof or their respective
            duly-authorized agents or attorneys. Subject to compliance with
            Section 2.3 hereof as to any transfer which may be involved in such

                                      -4-
<PAGE>

            division or combination, the Company shall execute and deliver a new
            Warrant or Warrants in exchange for the Warrant or Warrants to be
            divided or combined in accordance with such notice; PROVIDED, that
            no holder of this Warrant may divide the Warrant into a Warrant
            exercisable into less than 1,000 shares of Common Stock.

SEC. 2.5    EXPENSES OF DELIVERY OF WARRANTS. The Company shall pay all
            expenses, taxes and other charges payable in connection with the
            preparation, issuance and delivery of any Warrant hereunder;
            PROVIDED, HOWEVER, that the Warrantholder shall be required to pay
            any and all taxes which may be payable in respect of any transfer
            involved in the issuance and delivery of any certificate in a name
            other than that of the Warrantholder as then reflected upon the
            books of the Company.

SECTION 3.  RESTRICTIONS ON EXERCISE AND TRANSFER; REGISTRATION RIGHTS.

SEC. 3.1    RESTRICTIONS ON EXERCISE AND TRANSFER. The holder of this Warrant,
            as of the date of issuance hereof, represents to the Company that it
            is acquiring the Warrants for its own account for investment
            purposes and not with a view to the distribution thereof.
            Notwithstanding any provisions contained in this Warrant to the
            contrary, this Warrant and the related Warrant Shares shall not be
            transferable except pursuant to the proviso contained in the
            following sentence or upon the conditions specified in this Section
            3, which conditions are intended, among other things, to insure
            compliance with the provisions of the Act and applicable state law
            in respect of the transfer of this Warrant or such Warrant Shares.
            The holder of this Warrant, by its acceptance hereof, agrees that it
            will not transfer this Warrant or the related Warrant Shares prior
            to delivery to the Company of an opinion of such holder's counsel
            (as such opinion and such counsel are described in Section 3.2
            hereof) or until registration of such Warrant Shares under the Act
            has become effective or after a sale of such Warrant or Warrant
            Shares has been consummated pursuant to Rule 144 or Rule 144A under
            the Act; PROVIDED, HOWEVER, that such holder may freely transfer
            this Warrant or such Warrant Shares (without delivery to the Company
            or opinion of Counsel) (w) to one of its nominees, Affiliates or a
            nominee thereof, (x) to a pension or profit-sharing fund established
            and maintained for its employees or for the employees of any such
            Affiliate, (y) from a nominee to any of the aforementioned persons
            as beneficial owner of this Warrant or such Warrant Shares, or (z)
            to a Qualified Institutional Buyer (so long as such transfer is
            effected in compliance with Rule 144A under the Act).

SEC. 3.2    NOTICE OF INTENTION TO TRANSFER; OPINION OF COUNSEL. The
            Warrantholder, by its acceptance hereof, agrees that prior to any
            transfer of this Warrant or of the related Warrant Shares (other
            than as permitted by Section 3.1 hereof or pursuant to a
            registration under the Act), the Warrantholder will give written
            notice to the Company of its intention to effect such transfer,
            together with an opinion of Orrick, Herrington & Sutcliffe LLP, or
            such other counsel for the Warrantholder as shall be reasonably
            acceptable to the Company, to the effect that the proposed transfer


                                      -5-
<PAGE>

            of this Warrant and/or such Warrant Shares may be effected without
            registration under the Act, PROVIDED, HOWEVER, that the Company will
            reimburse the Warrantholder in full for the reasonable fees and
            disbursements of such counsel incurred by or on behalf of the
            Warrantholder in connection with obtaining of such opinion. Upon
            delivery of such notice and opinion to the Company, the
            Warrantholder shall be entitled to transfer this Warrant and/or such
            Warrant Shares in accordance with the intended method of disposition
            specified in the notice to the Company; PROVIDED, HOWEVER, that if
            such method of disposition would, in the opinion of the
            aforementioned counsel to the Warrantholder, require that the
            Company (a) take any action, and/or execute and file with the
            Commission and/or any applicable state securities authority, and/or
            (b) deliver to the Warrantholder or any other person any form or
            document (other than a registration statement under the Act or under
            any state securities laws or any action or documentation required
            solely a by federal or state banking regulatory body) in order to
            establish that the Warrantholder is entitled to take advantage of
            such method of disposition, the Company agrees promptly, at its
            expense, to take any such action and/or execute and file and/or
            deliver any such form or document, PROVIDED, FURTHER, that the
            Company shall not be required to provide a general consent to
            service of process or qualify as a foreign corporation in any
            jurisdiction solely by reason of this Section 3.2.

SEC. 3.3    [Reserved].

SEC. 3.4    PIGGYBACK REGISTRATIONS.

            (a)   If the Company at any time prior to June ___, 2001, proposes
                  to register any of its equity securities (as defined in the
                  Act), other than securities which are convertible into shares
                  of Common Stock, under the Act on Forms S-1, S-2 or S-3 (but
                  not Form S-4 or S-8 or any substantially similar form of
                  limited scope) or on any other form upon which may be
                  registered securities similar to the Warrant Shares, it will
                  at each such time give written notice at least 30 days prior
                  to the filing of the registration statement to all
                  Warrantholders of its intention so to do. Such notice shall
                  specify the proposed date of the filing of the registration
                  statement and advise each Warrantholder of its right to
                  participate therein. Upon the written request of any
                  Warrantholder given prior to the proposed date of filing set
                  forth in such notice, the Company will cause each Warrant
                  Share not otherwise covered under an effective registration
                  statement that such Warrantholder has requested the Company to
                  register to be registered under the Act, all to the extent
                  requisite to permit the sale or other disposition of such
                  Warrant Shares by such Warrantholder .

            (b)   If, in the written opinion of the underwriter or underwriters
                  managing the public offering which is the subject
                  of a registration pursuant to Section 3.4(a) (or in the event
                  that such distribution shall not be underwritten, in the
                  written opinion of an investment banking firm of recognized
                  standing satisfactory to the Warrantholders), the total amount
                  of the securities to be so registered, when added to the total

                                      -6-
<PAGE>

                  amount of Warrant Shares which the Warrantholders have
                  requested to be registered pursuant to Section 3.4(a), will
                  exceed the maximum amount of securities of the Company which
                  can be marketed (i) at a price reasonably related to their
                  then-current market value, or (ii) without otherwise
                  materially and adversely affecting the entire offering, then
                  the Company shall have the right to exclude from such
                  registration such number of Warrant Shares which it would
                  otherwise be required to register pursuant to Section 3.4(a)
                  as is necessary to reduce the total amount of securities to be
                  so registered to the maximum amount of securities which can be
                  so marketed; PROVIDED, HOWEVER, that if the securities (other
                  than the Warrant Shares) to be so registered for sale are to
                  be offered for the account of the Company and others, the
                  Company may only exclude Warrant Shares pro rata with the
                  securities held by such other persons (it being agreed that in
                  the case where such registration is to be effected as a result
                  of the exercise by a holder of the Company's securities of
                  such holder's right to cause such securities to be so
                  registered, such pro rata exclusion shall include the Company,
                  but shall not include such holder exercising its right to have
                  the securities so registered).

SEC. 3.5    COMPANY'S OBLIGATIONS IN REGISTRATION. If and whenever
            the Company is obligated by the provisions of this Section 3 to
            effect the registration of any Warrant Shares under the Act, the
            Company will keep the Warrantholder advised in writing as to the
            initiation of each registration and will use its best efforts to:

                  (a)   cause such registration statement to remain effective
                        during the period required for the distribution of the
                        securities covered by the registration statement (the
                        "Effectiveness Period"); PROVIDED, HOWEVER, that in the
                        event that the Warrant Shares covered by such
                        registration statement are not to be sold to or through
                        underwriters acting for the Company, the Company shall
                        not be required to keep such registration statement in
                        effect, or prepare and file any amendments or
                        supplements thereto, after the expiration of two years
                        following the date of this Warrant, SUBJECT, HOWEVER to
                        the following restrictions:

                             (i) If, at any time prior to the expiration of the
                           Effectiveness Period, counsel to the Company (which
                           counsel shall be experienced in securities laws
                           matters) has determined in good faith that it is
                           reasonable to conclude that the filing of a
                           registration statement or the compliance by the
                           Company with its disclosure obligations in
                           connection with such registration statement may
                           require the disclosure of information which the
                           Board of Directors of the Company has identified as
                           material and which the Board of Directors has
                           determined that the Company has a bona fide business
                           purpose for preserving as confidential, then the
                           Company may delay the filing or the effectiveness of
                           such registration statement (if not then filed or


                                      -8-
<PAGE>

                           effective, as applicable) and shall not be required
                           to maintain the effectiveness thereof or amend or
                           supplement such registration statement for a period
                           (an "Information Delay Period") expiring three
                           business days after the earlier to occur of (A) the
                           date on which such material information is disclosed
                           to the public or ceases to be material or the
                           Company is able to so comply with its disclosure
                           obligations and Commission requirements or (B) 45
                           days after the Company notifies the Holders of such
                           good faith determination. There shall not be more
                           than four Information Delay Periods during the
                           Effectiveness Period, and there shall not be two
                           Information Delay Periods during any contiguous 135
                           day period.

                             (ii) If, at any time prior to the expiration of
                           the Effectiveness Period, the Company is advised by
                           a nationally recognized investment banking firm
                           selected by the Company that, in such firm's written
                           reasonable opinion addressed to the Company, sales
                           of Common Stock pursuant to a registration statement
                           at such time would materially adversely affect any
                           immediately planned underwritten public equity
                           financing by the Company of at least $5 million, the
                           Company shall not be required to maintain the
                           effectiveness of such registration statement or
                           amend or supplement such registration statement for
                           a period (a "Transaction Delay Period") commencing
                           on the date of pricing of such equity financing and
                           expiring three business days after the earliest to
                           occur of (i) the abandonment of such financing or
                           (ii) 90 days after the completion of such financing.
                           There shall not be more than two Transaction Delay
                           Periods during the Effectiveness Period.

                                A Transaction Delay Period and an Information
                           Delay Period are hereinafter collectively referred to
                           as "Delay Periods" or a "Delay Period." The Company
                           will give prompt written notice, in the manner
                           prescribed by Section 10(b) hereof, to each Holder of
                           each Delay Period. Such notice shall be given (i) in
                           the case of a Transaction Delay Period, at least 20
                           days in advance of the commencement of such Delay
                           Period and (ii) in the case of an Information Delay
                           Period, as soon as practicable after the Board of
                           Directors makes the determination referenced in
                           Section 3.5(a)(i). Such notice shall state to the
                           extent, if any, as is practicable, an estimate of the
                           duration of such Delay Period. Each Holder agrees
                           that (i) upon receipt of such notice of an
                           Information Delay Period it will forthwith
                           discontinue disposition of any restricted securities
                           of the Company pursuant to the registration

                           Transaction Delay Period it will forthwith
                           discontinue disposition of the Common Stock pursuant
                           to the registration statement and (iii) in either
                           such case, will not deliver any prospectus forming a
                           part of the registration statement in connection with
                           any sale of restricted securities or Common Stock, as
                           applicable until the expiration of such Delay Period.

                  (b)   prepare and file with the SEC such amendments and
                        supplements to such registration statement and the
                        prospectus used in connection with such registration
                        statement as may be necessary to comply with the
                        provisions of the Act with respect to the disposition of
                        all securities covered by such registration statement;
                        PROVIDED, HOWEVER, that in any event, the Company's
                        obligations under this Section 3.5(b) shall terminate
                        two years after the effective date of this Agreement;

                  (c)   furnish such number of prospectuses and other
                        documents incident thereto, including any amendment of
                        or supplement to the prospectus, as the Warrantholder
                        from time to time may reasonably request;

                  (d)   notify the Warrantholder at any time when a
                        prospectus relating thereto is required to be delivered
                        under the Act of the happening of any event which would
                        cause the prospectus included in such registration
                        statement, as then in effect, to include an untrue
                        statement of a material fact or omit to state a material
                        fact required to be stated therein or otherwise
                        necessary to make the statements therein not misleading
                        or incomplete in the light of the circumstances then
                        existing, and prepare and furnish to the Warrantholder a
                        reasonable number of copies of a supplement to or an
                        amendment of such prospectus as may be necessary so
                        that, as thereafter delivered to the purchasers of such
                        shares, such prospectus shall not include an untrue
                        statement of a material fact or omit to state a material
                        fact required to be stated therein or necessary to make
                        the statements therein not misleading or incomplete in
                        the light of the circumstances then existing;

                  (e)   provide a transfer agent and registrar for all
                        Warrant Shares registered pursuant to such registration
                        statement and a CUSIP number for all such Warrant
                        Shares, in each case not later than the effective date
                        of such registration

                  (f)   use its reasonable efforts to register or qualify
                        the Warrant Shares covered by such registration
                        statement under such other securities or blue sky laws
                        of such jurisdictions as the Warrantholders for whom
                        such Warrant Shares are registered or are to be
                        registered shall reasonably request, and do any and all

                                      -9-

                        other reasonable acts and things to so register or
                        qualify which may be necessary or advisable to enable
                        such Warrantholders to consummate the disposition in
                        such jurisdictions of such Warrant Shares, PROVIDED,
                        HOWEVER, that the Company shall not be required to
                        provide a general consent to service of process or
                        qualify as a foreign corporation in any jurisdiction
                        solely by reason of this Section 3.5;

                  In connection with any underwritten offering effected pursuant
            to this Section 3, the Company will enter into an underwriting
            agreement reasonably necessary to effect the offer and sale of
            Common Stock, provided such underwriting agreement contains
            customary underwriting provisions and provided further that if the
            underwriter so requests, the underwriting agreement will contain
            customary indemnification and contribution provisions. To the extent
            reasonably necessary to effect the offer and sale of Common Stock in
            connection with any underwritten offering in which it is
            participating, the Warrantholder will agree to consent to and where
            applicable, be subject to the terms and conditions of such
            underwriting agreement.

SEC. 3.6    PAYMENT OF REGISTRATION EXPENSES. The costs and expenses
            of all registrations under the Act and of all other actions which
            the Company is required to take or effect pursuant to this Section 3
            shall be paid by the Company (including, without limitation, all
            registration, qualification and filing fees, printing expenses,
            expenses of distributing prospectuses and other documents, fees and
            disbursements of counsel and accountants for the Company, and
            expenses of any special audits incident to or required in connection
            with any such registration hereof, but excluding the fees and
            disbursements of special counsel for the Warrantholders, any
            consultants retained by the Warrantholders and underwriters' or
            brokers' discounts or commissions applicable to the Warrant Shares).

SEC. 3.7    INFORMATION FROM WARRANTHOLDERS. Notices and requests
            delivered by Warrantholders to the Company pursuant to this Section
            3 shall contain such information regarding the Warrant Shares and
            the intended method of disposition thereof as shall reasonably be
            required in connection with the action to be taken. To the extent
            that any Warrantholder fails to provide such information to the
            Company with respect to any of such Warrantholder's Warrant Shares,
            the Company shall be relieved of its obligation to maintain
            registration of such Warrant Shares until the such Warrantholder has
            provided the Company with the required information and the Company
            has had a reasonable time thereafter (but in no event more than 10
            calendar days) in which to incorporate such information into its
            registration materials.

SEC. 3.8    COMPANY'S INDEMNIFICATION. In the event of any registration
            under the Act of any Warrant Shares pursuant to this Section 3, the
            Company hereby agrees to indemnify and hold harmless each
            Warrantholder disposing of such Warrant Shares and each other
            person, if any, who controls such Warrantholder within the meaning
            of Section 15 of the Act, as well as each other person (including

                                      -10-

            underwriters) who participates in the offering of such Warrant
            Shares against any losses, claims, damages or liabilities, joint or
            several, to which such Warrantholder or controlling person or
            participating person may become subject under the Act or otherwise,
            in so far as such losses, claims, damages or liabilities (or
            proceedings in respect thereof): (a) arise out of or are based upon
            any untrue statement or alleged untrue statement of any material
            fact contained, on the effective date thereof: (i) in any
            registration statement under which such Warrant Shares were
            registered under the Act, (ii) in any preliminary prospectus or
            final prospectus contained therein, or (iii) in any amendment or
            supplement thereto, or (b) arise out of or are based upon the
            omission or alleged omission to state therein a material fact
            required to be stated therein or necessary to make the statements
            therein not misleading, and will reimburse such Warrantholder and
            each such controlling person or participating person for any legal
            or any other expenses incurred by such Warrantholder or such
            controlling person or participating person in connection with
            investigating or defending any such loss, claim, damage, liability
            or proceeding; PROVIDED, HOWEVER, that the Company will not be
            liable in any such case to the extent that any such loss, claim,
            damage or liability arises out of or is based upon (a) an untrue
            statement or alleged untrue statement or omission or alleged
            omission made in such registration statement, said preliminary or
            final prospectus or said amendment or supplement in reliance upon
            and in conformity with written information furnished to the Company
            by an instrument duly executed by such Warrantholder or such
            controlling or participating person, as the case may be,
            specifically for use in the preparation thereof or (b) an untrue
            statement or alleged untrue statement, omission or alleged omission
            in a prospectus, if such untrue statement or alleged untrue
            statement, omission or alleged omission is corrected in an amendment
            or supplement to the prospectus which amendment or supplement is
            delivered to such Warrantholder and such Warrantholder thereafter
            fails to deliver such prospectus as so amended or supplemented prior
            to or concurrently with such Warrantholder's sale of Warrant Shares
            to the person asserting such loss, claim, damage, liability or
            expense.

SEC. 3.9    WARRANTHOLDER'S INDEMNIFICATION. It shall be a condition of
            the Company's obligation under this Section 3 to effect any
            registration under the Act that there shall have been delivered to
            the Company an agreement or agreements duly executed by each
            Warrantholder for whom Warrant Shares are to be so registered,
            whereby such Warrantholder agrees to indemnify and hold harmless the
            Company, each other person referred to in subparts (1), (2) and (3)
            of Section 11(a) of Section 15 of the Act in respect of such
            registration statement and each other person, if any, which controls
            the Company within the meaning of the Act against any losses,
            claims, damages or liabilities, joint or several, to which the
            Company or its controlling person may become subject under the Act
            or otherwise, in so far as such losses, claims, damages or
            liabilities (or proceedings in respect thereof): (a) arise out of or
            are based upon any untrue statement or alleged untrue statement of
            any material fact contained, on the effective date thereof: (i) in
            any registration statement under which such Warrant Shares were
            registered under the Act, (ii) in any preliminary prospectus or
            final prospectus contained therein, or (iii) in any amendment or

                                      -11-

            supplement thereto, or (b) arise out of or are based upon the
            omission or alleged omission to state therein a material fact
            required to be stated therein or necessary to make the statements
            therein not misleading; and will reimburse the Company and each such
            controlling person for any legal or any other expenses incurred by
            the Company or such controlling person in connection with
            investigating or defending any such loss, claim, damage, liability
            or proceeding, PROVIDED, HOWEVER, that such Warrantholder shall be
            liable to the Company only to the extent that such losses, claims,
            damages or liabilities (or proceeding in respect thereof) arise out
            of or are based upon any untrue statement or alleged untrue
            statement of any material fact contained, on the effective date
            thereof, in any registration statement under which such Warrant
            Shares were registered under the Act, in any preliminary prospectus
            or final prospectus contained therein or in any amendment or
            supplement thereto, or arise out of or are based upon the omission
            or alleged omission to state therein a material fact required to be
            stated therein or necessary to make the statements therein not
            misleading, which, in each such case, has been made in or omitted
            from such registration statement, said preliminary or final
            prospectus or said amendment or supplement in reliance upon, and in
            conformity with, written information furnished to the Company by an
            instrument duly executed by such Warrantholder specifically for use
            in the preparation thereof. The Company shall be entitled to receive
            indemnities from underwriters, selling brokers, dealer managers and
            similar securities industry professionals participating in the
            distribution, to the same extent as provided above, with respect to
            information with respect to such persons so furnished in writing by
            such persons specifically for inclusion in any prospectus or
            registration statement.

SEC. 3.10   CONDUCT OF INDEMNIFICATION PROCEEDINGS. Any person entitled to
            indemnification hereunder will (a) give prompt written notice to the
            indemnifying party of any claim with respect to which it seeks
            indemnification and (b) unless, in such indemnified party's
            reasonable judgment, a conflict of interest may exist between such
            indemnified and indemnifying parties with respect to such claim,
            permit such indemnifying party to assume the defense of such claim
            with counsel reasonably satisfactory to the indemnified party;
            PROVIDED, HOWEVER, that the failure of an indemnified party to give
            notice as provided herein shall not relieve the indemnifying party
            of its obligations under this Section 3.10 with respect to such
            indemnified party, except to the extent that the indemnifying party
            is actually prejudiced by such failure. Whether or not such defense
            is assumed by the indemnifying party, the indemnifying party will
            not be subject to any liability for any settlement made without its
            consent (but such consent will not be unreasonably withheld). No
            indemnifying party will consent to the entry of any judgment or
            enter into any settlement which does not include as an unconditional
            term thereof the giving by the claimant or plaintiff to such
            indemnified party of a release from all liability in respect of such
            claim or litigation. An indemnifying party who is not entitled to,
            or elects not to, assume the defense of the claim against the
            indemnified party, will not be obligated to pay the fees and
            expenses of more than one counsel for all parties indemnified by
            such indemnifying party with respect to such claim, unless in the
            reasonable judgment of any indemnified party a conflict of interest

                                      -12-
<PAGE>

            may exist between such indemnified party and any other such
            indemnified parties with respect to such claim, in which event the
            indemnifying party shall be obligated to pay the fees and expenses
            of such additional counsel or counsels.

                  If for any reason the indemnification provided for in the
            preceding Sections 3.8 and 3.9 hereof is unavailable to an
            indemnified party as contemplated thereby, the indemnifying party
            shall contribute to the amount paid or payable by the indemnified
            party as a result of such loss, claim, damage or liability in such
            proportion as is appropriate to reflect not only the relative
            benefits received by the indemnified party and the indemnifying
            party, but also the relative fault of the indemnified party and the
            indemnifying party, as well as any other relevant equitable
            considerations. No person guilty of fraudulent misrepresentation
            (within the meaning of Section 11(f) of the Act) shall be entitled
            to contribution from any person who was not guilty of fraudulent
            misrepresentation.

SEC. 3.11   UNDERWRITING AGREEMENT INDEMNIFICATION PROVISIONS.
            Notwithstanding the provisions of Sections 3.8, 3.9 and 3.10 hereof,
            if an underwriting agreement executed by the Company pursuant to
            Section 3.5 hereof shall contain indemnification, contribution and
            related procedural provisions in a form customary to the underwriter
            which are substantially to the same effect as the provisions
            provided for in Sections 3.8, 3.9 and 3.10 hereof, such customary
            indemnification provisions shall be incorporated in such
            underwriting agreement in lieu of those provided for in Sections
            3.8, 3.9 and 3.10 hereof.

SEC. 3.12   PUBLIC INFORMATION. The Company covenants and agrees that if
            and so long as the Common Stock shall be registered under Section 12
            of the Exchange Act, at any time when any Warrantholder so entitled
            desires to make sales of any Warrant Shares in reliance on Rule 144
            or Rule 144A under the Act either (i) there will be available
            adequate current public information with respect to the Company as
            required by said Rules, or (ii) if such information is not available
            the Company will use its best efforts to make such information
            available without delay. Without limiting the foregoing, after the
            time of any such registration the Company will timely file with the
            Commission all reports required to be filed under Sections 13 and
            15(d) of the Exchange Act and will promptly furnish to any
            Warrantholder so requesting a written statement that the Company has
            complied with all such reporting requirements.

SEC. 3.13   NO CONFLICTING REGISTRATION RIGHTS. The Company covenants and
            agrees that if and so long as any Warrants or any Warrant Shares
            shall remain outstanding and the holders thereof shall have any
            rights under this Section 3, it will not enter into any agreement
            with any person creating any rights with respect to any shares of
            Common Stock or any other security in conflict with or inconsistent
            with any rights retained by any holder of Warrants or Warrant Shares
            pursuant to this Section 3.

SECTION 4.  ANTI-DILUTION PROVISIONS.

SEC. 4.1    ADJUSTMENT OF CURRENT WARRANT PRICE AND NUMBER OF SHARES
            PURCHASABLE. In the event that the Company shall (A) pay a dividend
            or make a distribution, in shares of Common Stock of the Company or
            any subsidiary which is not directly or indirectly wholly owned by
            the Company, (B) split or subdivide its outstanding Common Stock
            into a greater number of shares, or (C) combine its outstanding
            Common Stock into a smaller number of shares, then in each such
            case, the Current Warrant Price in effect immediately prior thereto
            shall be adjusted so that the Warrantholder shall be entitled to
            receive the number of shares of Common Stock that such Warrantholder
            would have owned or have been entitled to receive after the
            occurrence of any of the events described above had such warrant
            been converted immediately prior to the occurrence of such event.
            Any adjustment made pursuant to this Section 4.1 shall become
            effective immediately after the close of business on the record date
            in the case of a dividend or distribution and shall become effective
            immediately after the close of business on the effective date in the
            case of such subdivision, split or combination, as the case may be.
            Any shares of Common Stock issuable in payment of a dividend shall
            be deemed to have been issued immediately prior to the close of
            business on the record date for such dividend for purposes of
            calculating the number of outstanding shares of Common Stock under
            Sections 4.2(a) and (b).

SEC. 4.2    CALCULATION OF ADJUSTMENTS.

            (a)   In the event that the Company shall commit to issue or
                  distribute Common Stock or issue rights, warrants, options
                  or convertible or exchangeable securities entitling the
                  holder thereof to subscribe for or purchase, convert into
                  or exchange for Common Stock, in any such case at a price
                  per share less than the Current Market Price on the
                  earliest of (i) the date the Company shall enter into a
                  firm contract for such issuance or distribution, (ii) the
                  record date for the determination of stockholders entitled
                  to receive any such Common Stock or rights, warrants,
                  options or convertible or exchangeable securities, if
                  applicable, or (iii) the date of actual issuance or
                  distribution of any such Common Stock or rights, warrants,
                  options or convertible or exchangeable securities
                  (PROVIDED, HOWEVER, that the issuance of Common Stock upon
                  the exercise of rights, warrants, options or convertible or
                  exchangeable securities will not cause an adjustment in the
                  Current Warrant Price if no such event would have been
                  required at the time such right, warrant, option or
                  convertible or exchangeable security was issued), then the
                  Current Warrant Price in effect immediately prior to such
                  earliest date shall be reduced so that the Current Warrant
                  Price shall equal the price determined by multiplying the
                  Current Warrant Price in effect immediately prior to such
                  earliest date by the fraction:

                    (x)  whose numerator shall be the number of shares of Common
                         Stock outstanding on such date, plus the number of
                         shares which the aggregate offering price of the total
                         number of shares so offered would purchase at such
                         Current Market Price (such amount, with respect to any


                                      -14-

<PAGE>

                         such rights, warrants, options or convertible or
                         exchangeable securities, determined by multiplying the
                         total number of shares subject thereto by the exercise
                         price of such rights, warrants, options or convertible
                         or exchangeable securities and dividing the product so
                         obtained by the Current Market Price); and

                    (y)  whose denominator shall be the number of shares of
                         Common Stock outstanding on such date (including any
                         rights, warrants, options or convertible securities
                         issuable after giving effect to any anti-dilution
                         provisions of the Company's other securities as a
                         result of such Adjustment Event), plus the number of
                         additional shares of Common Stock to be issued or
                         distributed or receivable upon exercise of any such
                         right, warrant, option or convertible or exchangeable
                         security.

                  Such adjustment shall be made successively whenever any such
                  Common Stock, rights, warrants, options or convertible or
                  exchangeable securities are issued or distributed. In
                  determining whether any rights, warrants or options entitle
                  the holders to subscribe for or purchase shares of Common
                  Stock at less than Current Market Price, and in determining
                  the aggregate offering price of shares of Common Stock so
                  issued or distributed, there shall be taken into account any
                  consideration received by the Company for such Common Stock,
                  rights, warrants, options or convertible or exchangeable
                  securities, the value of such consideration, if other than
                  cash, to be determined by the Board of Directors, whose good
                  faith determination shall be conclusive, and described in a
                  certificate filed with the Company's corporate records. If any
                  right, warrant, option or convertible or exchangeable security
                  to purchase or acquire Common Stock, the issuance of which
                  resulted in an adjustment in the Conversion Price pursuant to
                  this Section 4.2 shall expire and shall not have been
                  exercised, the Current Warrant Price shall immediately upon
                  expiration be recomputed to the Current Warrant Price which
                  would have been in effect had the adjustment of the Current
                  Warrant Price made upon the issuance of such right, warrant,
                  option or convertible or exchangeable security been made on
                  the basis of offering for subscription, purchase or issuance,
                  as the case may be, only of that number of shares of Common
                  Stock actually purchased or issued upon the actual exercise of
                  such right, warrant, option or convertible or exchangeable
                  security.

             (b)  No adjustment in the Current Warrant Price shall be required
                  unless the adjustment would require an increase or decrease of
                  at least 1% in the Current Warrant Price, PROVIDED, HOWEVER,
                  that any adjustments that by reason of this Section 4.2(b) are
                  not required to be made shall be carried forward and taken
                  into account in any subsequent adjustment.  All calculations
                  under this Section 4.2(b) shall be made to the nearest cent.

             (c)  Notwithstanding anything to the contrary set forth in this
                  Section 4.2, no adjustment shall be made to the Current
                  Warrant Price upon (A) the issuance of shares of Common Stock
                  pursuant to any compensation or incentive plan for officers,
                  employees or consultants of the Company which plan has been
                  directors, duly approved on or prior to the date of this
                  Warrant by the Compensation Committee of the Board of
                  Directors (or if there is no such committee then serving, by
                  the majority vote of the Directors then serving who are not
                  (i) employees or officers of the Company, (b) 5% or greater
                  stockholders of the Company, or (c) of an officer, employee
                  or affiliate of any such 5% or greater stockholder) and, if
                  required by law, the requisite vote of the stockholders of
                  the Company (unless the exercise price or maximum
                  authorized number of shares of Common Stock issuable under
                  such plan is changed after the date hereof, other than by
                  operation of the anti-dilution provisions hereof); or ( B)
                  the issuance of Common Stock upon the conversion or
                  exercise of any option or warrant of the Company
                  outstanding as of the date of this warrant, unless the
                  conversion or exercise price thereof is changed thereafter
                  (other than solely by operation of the anti-dilution
                  provisions of such options or warrants).

             (d)  The Company from time to time may reduce the Current Warrant
                  Price by any amount for any period of time in the discretion
                  of the Board of Directors. A voluntary reduction of the
                  Current Warrant Price does not change or adjust the Current
                  Warrant Price otherwise in effect for purposes of this Section
                  4.2.

SEC. 4.3    EFFECT OF MERGER OR CONSOLIDATION. In case the Company shall, while
            this Warrant remains outstanding, enter into any consolidation with
            or merger into any other corporation wherein the Company is not the
            surviving corporation, or wherein securities of a corporation other
            than the Company are distributable to holders of Common Stock, or
            sell or convey its property as an entirety or substantially as an
            entirety followed by distribution of any or all of the proceeds
            thereof to shareholders, and in connection with such consolidation,
            merger, sale or conveyance, shares of stock or other securities or
            property shall be issuable or deliverable in exchange for the Common
            Stock, then, as a condition of such consolidation, merger, sale or
            conveyance, lawful and adequate provision shall be made whereby the
            Warrantholder shall thereafter be entitled to purchase pursuant to
            this Warrant (in lieu of the number of shares of Common Stock which
            such Warrantholder would have been entitled to purchase immediately
            prior to such consolidation, merger, sale or conveyance) the shares
            of stock or other securities or property to which a holder of any
            equal number of shares of Common Stock would have been entitled at
            the time of such consolidation, merger, sale or conveyance, at an
            aggregate purchase price equal to that which would have been payable
            if such number of shares of Common Stock had been purchased by
            exercise of this Warrant immediately prior thereto. In case of any
            such consolidation, merger, sale or conveyance, appropriate


                                      -16-
<PAGE>

            provisions shall be made with respect to the rights and interests
            thereafter of the Warrantholders, to the end that all the provisions
            of the Warrants (including the provisions of this Section 4) shall
            thereafter be applicable, as nearly as practicable, to such stock or
            other securities or property thereafter deliverable upon the
            exercise of the Warrants. The Company shall not effect any such
            consolidation, merger, sale or conveyance unless prior to or
            simultaneously with the consummation thereof, the successor
            corporation (if other than the Company) resulting from such
            consolidation or merger or purchasing such assets shall assume by
            written instrument, executed and mailed or delivered to each
            Warrantholder, the obligation to deliver to such Warrantholder such
            shares of stock or other securities or property as such
            Warrantholder may be entitled to receive in accordance with the
            foregoing provisions, which instrument shall contain the express
            assumption by such successor corporation of the due and punctual
            performance and observance of every provision of this Warrant to be
            performed and observed by the Company and of all liabilities and
            obligations of the Company hereunder.

SEC. 4.4    REORGANIZATION OR RECLASSIFICATION. In case of any capital
            reorganization or any reclassification of the capital stock of the
            Company (except as provided in Section 4.3 hereof) while this
            Warrant remains outstanding, then, as a condition of such
            reorganization or reclassification, lawful and adequate provision
            shall be made whereby the holder of this Warrant shall thereafter be
            entitled to purchase pursuant to this Warrant (in lieu of the number
            of shares of Common Stock which such holder would have been entitled
            to purchase immediately prior to such reorganization or
            reclassification) the shares of stock of any class or classes or
            other securities or property to which the holders of such number of
            shares of Common Stock would have been entitled at the time of such
            reorganization or reclassification, at an aggregate purchase price
            equal to that which would have been payable if such number of shares
            of Common Stock had been purchased immediately prior to such
            reorganization or reclassification. In case of any such capital
            reorganization or reclassification, appropriate provisions shall be
            made with respect to the rights and interests thereafter of the
            Warrantholders, to the end that all the provisions of the Warrants
            (including the provisions of this Section 4) shall thereafter be
            applicable, as nearly as practicable, to such stock or other
            securities or property thereafter deliverable upon the exercise of
            the Warrants.

SEC. 4.5    STATEMENT OF ADJUSTMENT. Upon each adjustment of the Current
            Warrant Price and the number of shares of Common Stock purchasable
            hereunder, and in the event of any change in the rights of the
            Warrant holder by reason of other events herein set forth, then and
            in each such case, the Company will promptly prepare a schedule
            setting forth the adjusted Current Warrant Price and the adjusted
            number of shares purchasable hereunder, or specifying the other
            shares of stock, other securities or property and the amount thereof
            receivable as a result of such change in rights, and setting forth
            in reasonable detail the method of calculation and the facts upon
            which such calculation is base. The Company will promptly mail a
            copy of such schedule to the registered holder of this Warrant.

SEC. 4.6    DETERMINATIONS BY THE BOARD OF DIRECTORS. All determinations
            by the Board of Directors of the Company under this Warrant shall be
            made in good faith with due regard to the interests of the holder of
            this Warrant and the other holders of securities of the Company and
            in accordance with good financial practice, and all valuations made
            by the Board of Directors of the Company under the terms of this
            Warrant must be made with due regard to any market quotations of
            securities involved in, or related to, the subject of such
            valuation.

SEC. 4.7    NOTIFICATIONS BY THE COMPANY.  In case at any time the
            Company proposes:

               (a)  to pay any dividend payable in stock (of any class or
                    classes) or in Convertible Securities upon Common Stock or
                    make any distribution to the holders of the Common Stock; or

               (b)  to make an offer for subscription pro rata to the holders of
                    Common Stock of any additional shares of stock of any class
                    or other rights or to grant to the holders of Common Stock
                    generally any rights, warrants or options; or

               (c)  to effect any capital reorganization or reclassification of
                    the capital stock of the Company, or consolidation or merger
                    of the Company with, or sale of all or substantially all of
                    its assets to, another corporation; or

               (d)  to effect a voluntary or involuntary dissolution,
                    liquidation or winding-up of the Company;

            then, in any one or more such cases, the Company shall give written
            notice to the registered holder of this Warrant of the date on which
            (i) the transfer books of the Company shall close or a record date
            shall be taken for such dividend, distribution, subscription rights
            or grant, or (ii) a record date shall be taken to determine
            stockholders entitled to notice of and to vote at any meeting of
            stockholders at which any such proposed reorganization,
            reclassification, consolidation, merger, sale of assets,
            dissolution, liquidation or winding-up is to be considered, or (iii)
            such reorganization, reclassification, consolidation, merger, sale
            of assets, dissolution, liquidation or winding-up shall take place,

                  CERTAIN COVENANTS OF THE COMPANY

      The Company covenants and agrees that:

               (a)  it will reserve and set apart and have at all times, free
                    from preemptive rights, a number of shares of authorized but
                    unissued Common Stock or other securities or property
                    deliverable upon the exercise of the Warrants sufficient to
                    enable it at any time to fulfill all its obligations
                    thereunder;

               (b)  before taking any action which would cause an adjustment
                    reducing the Current Warrant Price below the then par value
                    of the shares of Common Stock issuable upon exercise of the
                    Warrants, it will take any corporate action which may be
                    necessary in order that the Company may validly and legally
                    issue fully paid and nonassessable shares of such Common
                    Stock at such adjusted Current Warrant Price;

               (c)  if any shares of Common Stock required to be reserved for
                    the purposes of the exercise of this Warrant require
                    registration with or approval of any governmental authority
                    under any federal law (other than the Act) or under any
                    state law before such shares may be issued upon exercise of
                    this Warrant, the Company will, at its expense, as
                    expeditiously as possible, cause such shares to be duly
                    registered or approved, as the case may be;

               (d)  if and so long as the Common Stock is listed on any national
                    securities exchange (as defined in the Exchange Act), it
                    will, at its expense, obtain and maintain the approval for
                    listing upon official notice of issuance of all shares of
                    Common Stock issuable upon the exercise of the Warrants at
                    the time outstanding and maintain the listing of such shares
                    after their issuance; and the Company will so list on such
                    national securities exchange, will register under the
                    Exchange Act (or any similar statute then in effect) and
                    will maintain such listing of any other securities that at
                    any time are issuable upon exercise of the Warrants if, and
                    at the time that, any securities of the same class shall be
                    listed on such national securities exchange by the Company;
                    and

               (e)  this Warrant shall be binding upon any corporation
                    succeeding to the Company by merger, consolidation or
                    acquisition of all or substantially all of the Company's
                    assets.

SECTION 7.  NOTICE.

      Any notice or other document required to be given or delivered to the
Warrantholders shall be delivered at, or sent by certified or registered mail
to, each such holder at the last address shown on the books of the Company
maintained at the Warrant Office for the registration and registration of
transfer of the Warrants or at any more recent address of which any
Warrantholder shall have notified the Company in writing. Any notice or other
document required or permitted to be given or delivered to holders of record of
outstanding Warrant Shares shall be delivered at, or sent by certified or
registered mail to, each such holder at such holder's address as the same
appears on the stock records of the Company. Any notice or other document
required or permitted to be given or delivered to the Company, other than such
notice or documents required to be delivered to the Warrant Office, shall be
delivered at, or sent by certified or registered mail to, the office of the
Company at 13595 Dulles Technology Drive, Herndon, Virginia 22071, or such other
address within the United States of America as shall have been furnished by the
Company to the Warrantholders and the holders of record of Warrant Shares. Any
notice or other document sent by certified or registered mail, return receipt
requested, shall be deemed to have been delivered and received when sent if the
receipt is appropriately completed and returned. Notices or documents delivered
in any other manner shall be deemed to have been delivered only when and if
received.

SECTION 8.  LIMITATIONS OF LIABILITY; NOT STOCKHOLDERS.

      No provision of this Warrant shall be construed as conferring upon the
holder hereof the right to vote, consent, receive dividends or receive notice
other than as herein expressly provided in respect of meetings of stockholders
for the election of directors of the Company or any other matter whatsoever as a
stockholder of the Company. No provision hereof, in the absence of affirmative
action by the holder hereof to purchase shares of Common Stock, and no mere
enumeration herein of the rights or privileges of the holder hereof, shall give
rise to any liability of such holder for the purchase price of any Warrant
Shares or as a stockholder of the Company, whether such liability is asserted by
the Company or by creditors of the Company.

SECTION 9.  LOSS, DESTRUCTION, ETC. OF WARRANTS.

      Upon receipt of evidence satisfactory to the Company of the loss, theft,
mutilation or destruction of any Warrant, and in the case of any such loss,
theft or destruction upon delivery of a bond of indemnity in such form and
amount as shall be reasonably satisfactory to the Company, or in the event of
such mutilation upon surrender and cancellation of the Warrant, the Company will
make and deliver a new Warrant, of like tenor, in lieu of such lost, stolen,
destroyed or mutilated Warrant; PROVIDED, HOWEVER, that neither the original
recipient of this Warrant pursuant to the Credit Agreement nor any other
financial institution having combined net capital, capital surplus and undivided
profits in excess of $50,000,000 which shall become a Warrantholder shall be
required to provide any such bond of indemnity. Any Warrant issued under the
provisions of this Section 9 in lieu of any Warrant alleged to be lost,
destroyed or stolen, or in lieu of any mutilated Warrant, shall constitute an
original contractual obligation on the part of the Company.

SECTION 10.  LAW GOVERNING.

      This Warrant shall be governed by, and construed and enforced in
accordance with, the law of the State of California.

    1. Delay Periods; Suspension of Sales.
    If at any time prior to the expiration of the Effectiveness Period counsel
    to the Company (which counsel shall be experienced in securities laws
    matters) has determined in good faith that it is reasonable to conclude that
    the filing of the Shelf Registration Statement or the compliance by the
    Company with its disclosure obligations in connection with the Shelf
    Registration Statement may require the disclosure of information which the
    Board of Directors of the Company has identified as material and which the
    Board of Directors has determined that the Company has a bona fide business
    purpose for preserving as confidential, then the Company may delay the
    filing or the effectiveness of the Shelf Registration Statement (if not then
    filed or effective, as applicable) and shall not be required to maintain the
    effectiveness thereof or amend or supplement the Shelf Registration
    Statement for a period (an "Information Delay Period") expiring three
    business days after the earlier to occur of (A) the date on which such
    material information is disclosed to the public or ceases to be material or
    the Company is able to so comply with its disclosure obligations and
    Commission requirements or (B) 45 days after the Company notifies the
    Holders of such good faith determination. There shall not be more than four
    Information Delay Periods during the Effectiveness Period, and there shall
    not be two Information Delay Periods during any contiguous 135 day period.
    (b) If at any time prior to the expiration of the Effectiveness Period the
    Company is advised by a nationally recognized investment banking firm
    selected by the Company that, in such firm's written reasonable opinion
    addressed to the Company, sales of Common Stock pursuant to the Shelf
    Registration Statement at such time would materially adversely affect any
    immediately planned underwritten public equity financing by the Company of
    at least $5 million, the Company shall not be required to maintain the
    effectiveness of the Shelf Registration Statement or amend or supplement the
    Shelf Registration Statement for a period (a "Transaction Delay Period")
    commencing on the date of pricing of such equity financing and expiring
    three business days after the earliest to occur of (i) the abandonment of
    such financing or (ii) 90 days after the completion of such financing. There
    shall not be more than two Transaction Delay Periods during the
    Effectiveness Period.

    A Transaction Delay Period and an Information Delay Period are hereinafter
    collectively referred to as "Delay Periods" or a "Delay Period." The Company
    will give prompt written notice, in the manner prescribed by Section 10(b)
    hereof, to each Holder of each Delay Period.  Such notice shall be given
    (i) in the case of a Transaction Delay Period, at least 20 days in advance
    of the commencement of such Delay Period and (ii) in the case of an
    Information Delay Period, as soon as practicable after the Board of
    Directors makes the determination referenced in Section 3(a).  Such notice
    shall state to the extent, if any, as is practicable, an estimate of the
    duration of such Delay Period. Each Holder, by his acceptance of any
    Transfer Restricted Securities, agrees that (i) upon receipt of such notice
    of an Information Delay Period it will forthwith discontinue disposition of
    Transfer Restricted Securities pursuant to the Shelf Registration Statement,
    (ii) upon receipt of such notice of a Transaction Delay Period it will
    forthwith discontinue disposition of the Common Stock pursuant to the Shelf
    Registration Statement and (iii) in either such case, will not deliver any
    prospectus forming a part of the Shelf Registration Statement in connection
    with any sale of Transfer Restricted Securities or Common Stock, as
    applicable until the expiration of such Delay Period.


THIS WARRANT AND THE SHARES  ISSUABLE UPON ITS EXERCISE HAVE NOT BEEN REGISTERED
WITH THE U.S.  SECURITIES AND EXCHANGE  COMMISSION UNDER THE U.S. SECURITIES ACT
OF 1933  ("ACT"),  AND  THEY MAY NOT BE  SOLD,  OFFERED  FOR  SALE,  PLEDGED  OR

                             STOCK PURCHASE WARRANT
                 RIGHT TO PURCHASE 7,500 SHARES OF COMMON STOCK


THIS CERTIFIES THAT ___________________ and all registered and permitted assigns
(collectively,  "Holder") is entitled to purchase, on or before _________, 2004,
_________ shares of the common stock ("Common Stock") of Netrix Corporation (the
"Corporation"   or   "Company")   upon  exercise  of  this  Warrant  along  with
presentation of the full purchase price as provided  herein.  The purchase price
of the common stock upon exercise of this Warrant ("Warrant Shares") is equal to
seven USD $______ per share (the "Exercise  Price").  The purchase price of this
Warrant is $10.00.

1. EXERCISE OF WARRANT.

(a) This  Warrant may be exercised in whole or in part on any business day on or
before the expiration date listed above by presentation  and surrender hereof to
the  Company at its  principal  office of an exercise  request and the  Exercise
Price in lawful  money of the  United  States of  America  in the form of a wire
transfer  or check,  subject to  collection,  for the  number of Warrant  Shares
specified in the exercise  request.  If this Warrant should be exercised in part
only, the Company shall,  upon surrender of this Warrant,  execute and deliver a
new Warrant  evidencing the rights of the Holder thereof to purchase the balance
of the Warrant Shares purchasable hereunder. Upon receipt by the Company of this
Warrant  and an  exercise  request  and  representations,  together  with proper
payment of the Exercise Price, at such office,  the Holder shall be deemed to be
the  holder of  record of the  Warrant  Shares,  notwithstanding  that the stock
transfer  books  of the  Company  shall  then be  closed  or  that  certificates
representing  such Warrant  Shares  shall not then be actually  delivered to the
Holder. The Company shall pay any and all transfer agent fees, documentary stamp
or similar  issue or transfer  taxes payable in respect of the issue or delivery
of the Warrant Shares.

(b) At any time  during the  Exercise  Period,  the Holder  may,  at its option,
exchange  this  Warrant,  in whole or in part (a "Warrant  Exchange"),  into the
number of Warrant Shares  determined in accordance with this Section (1)(b),  by
surrendering this Warrant at the principal office of the Company, accompanied by
a written  notice  stating such  Holder's  intent to effect such  exchange,  the
number of  Warrant  Shares  to be  exchanged  and the date on which  the  Holder
requests  that such  Warrant  Exchange  occur (the  "Notice of  Exchange").  The
Warrant Exchange shall take place on the date the Notice of Exchange is received
by the Company or such later date as may be  specified in the Notice of Exchange
(the "Exchange  Date").  Certificates  for the shares issuable upon such Warrant
Exchange and, if applicable,  a new Warrant of like tenor evidencing the balance
of the  shares  remaining  subject  to this  Warrant,  shall be issued as of the
Exchange Date and  delivered to the Holder  within seven (7) days  following the
Exchange  Date.  In  connection  with any Warrant  Exchange,  this Warrant shall
represent  the right to subscribe  for and acquire the number of Warrant  Shares
(rounded to the next highest  integer) equal to (i) the number of Warrant Shares
specified by the Holder in its Notice of Exchange (the "Total Number") less (ii)
the number of Warrant Shares equal to the quotient  obtained by dividing (A) the
product of the Total Number and the existing  Exercise  Price by (B) the current
market  value of a share of Common  Stock.  Current  market  value  shall be the
average closing price for the 3-day period prior to the Exchange Date.

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES  DELIVERABLE  UPON EXERCISE
OF WARRANT.

The  Exercise  Price and the number of Shares  purchasable  upon the exercise of
this Warrant are subject to adjustment  from time to time upon the occurrence of
the events enumerated in this paragraph.

(a) In case the Corporation shall at any time after the date of this Warrant:

         (i)  Pay a  dividend  of its  shares  of its  Common  Stock  or  make a
distribution  in shares,  or rights or warrants to purchase shares of its Common
Stock with respect to its outstanding Common Stock;

         (ii) Subdivide its outstanding shares of Common Stock;

         (iii) Combine its outstanding shares of Common Stock; or

         (iv) Issue any other shares of capital stock by reclassification of its
shares of Common Stock

the Exercise Price in effect and the number of Warrant Shares purchasable at the
time  of  the  record  date  of  such  dividend,  subdivision,  combination,  or
reclassification  shall be  proportionately  adjusted  so that  Holder  shall be
entitled  to receive  the  aggregate  number and kind of shares  which,  if this
Warrant had been  exercised  prior to such event,  Holder  would have owned upon
such  exercise  and  been  entitled  to  receive  by  virtue  of such  dividend,
subdivision,  combination,  or  reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.

(b) In  case  of  any  reorganization  of the  Corporation,  or in  case  of any
reclassification or change of outstanding Common Stock issuable upon exercise of
this  Warrant  (other  than a change in par  value,  or from par value to no par
value,  or from no par value to par value,  or as a result of a  subdivision  or
split-up or combination of the Common Stock), or in case of any consolidation or
merger of the Company with or into another entity (other than a consolidation or
merger with a subsidiary or a continuing corporation), or in case of any sale or
conveyance to another entity of all or substantially  all of the property of the
Corporation,  then,  as a condition  of such  reorganization,  reclassification,
change,  consolidation,  merger,  sale, or conveyance,  the  Corporation or such
successor or purchasing  entity,  as the case may be, shall forthwith provide to
Holder a supplemental warrant (the "Supplement  Warrant") which will make lawful
and  adequate  provision  whereby  Holder  shall  have the right  thereafter  to
receive,  upon  exercise of such  Supplemental  Warrant,  the kind and amount of
shares and other  securities  and property  which would have been  received upon
such reorganization,  reclassification,  change, consolidation, merger, sale, or
conveyance by a holder of a number of shares of Common Stock equal to the number
of Shares  issuable  upon  exercise of this  Warrant  immediately  prior to such
reorganization,   reclassification,  change,  consolidation,  merger,  sale,  or
conveyance.  Such Supplemental  Warrant shall include provisions for adjustments
which shall be as nearly  equivalent as may be  practicable  to the  adjustments
provided for in this  paragraph.  The above  provisions of this paragraph  shall
similarly apply to successive consolidations, mergers, sales, or conveyances.


3. REGISTRATION RIGHTS.

The Company  will  use  its  best efforts to ensure that shares  underlying this
Warrant be registered in the next  registration  statement filed by the Company.
Otherwise;

(1) The Company shall advise the Holder of this Warrant or of the Warrant Shares
or  any  then  holder  of  Warrants  or  Warrant   Shares  (such  persons  being
collectively  referred to herein as  "holders")  by written  notice at least two
weeks  prior to the  filing  of any new  registration  statement  ("Registration
Statement") under the Securities Act of 1933 (the "Act") covering  securities of
the  Company,  other than a  Registration  Statement  filed with  respect to any
employee  benefit plan or an offering solely related to an acquisition for which
such Warrant Shares cannot be appropriately  registered or which does not permit
registration  of the Warrants or Warrant  Shares,  and will for a period of five
years,  from  the date of this  Warrant  upon the  request  of any such  holder,

                                       2

<PAGE>

include in any such  registration  statement the number of Warrant Shares holder
desires to  include in the  Registration  Statement.  In the event the  managing
underwriter for any said registration  advises the Company that the inclusion of
the Warrant  Shares  would be  detrimental  to the  offering,  then such Warrant
Shares shall be included in the Registration Statement only if the Holder agrees
in writing, for a period of up to 120 days following such offering,  not to sell
or  otherwise   dispose  of  the  Warrant  Shares.   The  Company  shall  supply
prospectuses  and  other  documents  as the  Holder  may  request  in  order  to
facilitate  the public sale or other  disposition of the Warrant Shares for sale
in such states where the Company qualifies its other securities  pursuant to the
Registration  Statement  for sale and do any and all other acts and things which
may be necessary or  desirable to enable such Holders to  consummate  the public
sale or other disposition of the Warrant or Warrant Shares.  The Holder need not
exercise  the Warrant to have the  Warrant  Shares  included  in a  registration
statement.  Nothing in this Section shall be construed to extend the  expiration
date of this Warrant.

(2) The following provision of this Section shall also be applicable:

         (A)  The  Company  shall  bear  the  entire  cost  and  expense  of any
registration of securities  initiated by it notwithstanding that Warrants Shares
subject to this  Warrant may be included  in any such  registration.  Any holder
whose  Warrant  Shares are included in any such  registration  statement  shall,
however,  bear  the fees of his own  counsel,  transfer  taxes  or  underwriting
discounts or  commissions  applicable to the Warrant Shares sold by him pursuant
thereto.

         (B)  Neither  the  giving of any notice by any holder nor making of any
request  for  prospectus  shall  impose  upon such  holder or owner  making such
request any obligation to sell any Warrant Shares, or exercise any Warrants.

         The Company's agreements with respect to Warrant Shares in this Section
shall  continue in effect  regardless  of the  exercise  and  surrender  of this
Warrant.

4. ASSIGNMENT OR LOSS OF WARRANT.

(a) Any sale, transfer,  assignment,  hypothecation or other disposition of this
Warrant  or of the  Warrant  Shares  shall  only be made if any  such  transfer,
assignment  or other  disposition  will  comply  with  the  rules  and  statutes
administered  by the Securities  and Exchange  Commission and (i) a Registration
Statement under the Act including such Shares is currently in effect, or (ii) in
the opinion of counsel,  which  counsel and which  opinion  shall be  reasonably
satisfactory to the Company,  a current  Registration  Statement is not required
for such disposition of the shares. Each stock certificate  representing Warrant
Shares issued upon exercise or exchange of this Warrant shall bear the following
legend (unless, in the opinion of counsel, which counsel and which opinion shall
be reasonably satisfactory to the Company, such legend is not required):

          "THE SECURITIES  EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED  UNDER THE  SECURITIES ACT OF 1933 AND MAY NOT BE
          TRANSFERRED  EXCEPT UPON DELIVERY TO THE  CORPORATION  OF AN
          OPINION OF COUNSEL  SATISFACTORY IN FORM AND SUBSTANCE TO IT
          THAT SUCH  TRANSFER WILL NOT VIOLATE THE  SECURITIES  ACT OF
          1933, AS AMENDED."

(b) The Holder  understands  that the Company may place,  and may  instruct  any
transfer agent or depository  for the Shares to place, a stop transfer  notation
in the securities records in respect of the Shares.

(c) Upon  receipt of evidence  satisfactory  to the Company of the loss,  theft,
destruction  or mutilation of this Warrant,  and (in the case of loss,  theft or
destruction) of indemnification  satisfactory to the Company, and upon surrender
of this  Warrant,  if  mutilated,  the Company  shall  execute and deliver a new
Warrant of like tenor and date.

5. RESERVATION OF SHARES.

                                       3
<PAGE>

The Company hereby agrees that at all times there shall be reserved for issuance
and delivery  upon exercise or exchange of this Warrant all shares of its Common
Stock or other shares of capital stock of the Company from time to time issuable
upon  exercise  or  exchange  of this  Warrant.  All such  shares  shall be duly
authorized  and,  when  issued  upon the  exercise or exchange of the Warrant in
accordance  with the terms  hereof,  shall be  validly  issued,  fully  paid and
nonassessable,  free and clear of all liens,  security  interests,  charges  and
other  encumbrances  or  restrictions  on sale  (other  than as  provided in the
Company's  articles  of  incorporation  and any  restrictions  on sale set forth
herein or pursuant to applicable federal and state securities laws) and free and
clear of all preemptive rights.

6. NOTICES TO WARRANT HOLDERS. NO SHAREHOLDER RIGHTS.

So long as this Warrant shall be  outstanding,  (i) if the Company shall pay any
dividend or make any  distribution  upon the Common Stock or (ii) if the Company
shall offer to the holders of Common Stock for  subscription or purchase by them
any  share  of  any  class  or  any  other   rights  or  (iii)  if  any  capital
reorganization  of the  Company,  reclassification  of the capital  stock of the
Company,   consolidation   or  merger  of  the  Company  with  or  into  another
corporation, sale, lease or transfer of all or substantially all of the property
and assets of the Company to another  corporation,  or voluntary or  involuntary
dissolution, liquidation or winding up of the Company shall be effected, then in
any such case,  the Company  shall cause to be mailed by  certified  mail to the
Holder,  at least  fifteen  days  prior the  date,  as the case may be, a notice
containing a brief  description  of the proposed  action and stating the date on
which such  action is to take place and the date,  if any is to be fixed,  as of
which the holders of Common  Stock or other  securities  shall  receive  cash or
other  property   deliverable   upon  such   reclassification,   reorganization,
consolidation, merger, conveyance, dissolution, liquidation or winding up.

Nothing in this Warrant shall be construed as conferring  upon the Holder or its
transferees  any rights as a stockholder in the Company,  including the right to
vote, receive dividends,  consent or receive notices as a stockholder in respect
to any meeting of stockholders.

7. ARBITRATION.

In the event that a dispute  arises  between the  Corporation  and the Holder of
this  Warrant as to any matte  relating  to this  Warrant,  the matter  shall be
settled  by  arbitration  in New York,  NY in  accordance  with the Rules of the
American  Arbitration  Association and the award rendered by such  arbitrator(s)
shall not be subject to appeal and may be entered in any  federal or state court
located in New York having  jurisdiction  thereof,  and  actions or  proceedings
shall be brought in no other forum or venue.

IN WITNESS  WHEREOF,  the  Corporation has caused this Warrant to be executed by
its duly authorized officers effective this 11th day of May, 1999.

                    AMENDMENT TO LOAN AND SECURITY AGREEMENT

                         NETRIX CORPORATION ("BORROWER")


      This AMENDMENT TO LOAN AND SECURITY  AGREEMENT (this "Amendment") dated as
of this ___ day of April,  1999,  between Coast Business  Credit,  a division of
Southern  Pacific  Bank  ("Coast"),  and  Borrower,  is made in reference to the
following facts:

      A.    Borrower  previously entered into a Loan and Security Agreement with
            Coast  dated  November  18,  1997  ("Loan  Agreement")  and  related
            documents connected therewith (as each may be amended, supplemented,
            replaced or modified from time to time, the "Loan Documents"). Terms
            used  herein,  unless  otherwise  defined  herein,  shall  have  the
            meanings set forth in the Loan Agreement.

      B.    Borrower  has caused an Event of Default  under  Section  8.1 of the
            Loan Agreement as a result of, among other  reasons,  the failure of
            Borrower to comply with the  Tangible Net Worth  requirements  under
            the Loan Agreement.

      C.    Borrower has requested that Coast waive the Event of Default, modify
            the Tangible Net Worth  requirements  under the Loan Agreement,  and
            extend the Maturity Date.

      D.    Coast is willing to amend the Loan  Agreement and waive the Event of
            Default on the terms and subject to the conditions set forth in this
            Amendment.

      NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  terms and
conditions hereof,  the parties do hereby agree as follows,  effective as of the
date set forth above.

      1. LIMITED  WAIVER.  Subject to terms and  conditions  of this  Amendment,
Coast hereby waives the Event of Default under Section 8.1 of the Loan Agreement
due to the failure of borrower to maintain a Tangible Net Worth of not less than
$13,500,000 for the months of October 1998, November 1998 and December 1998.

            The foregoing  waiver is a one-time waiver only and not a continuing
waiver,  and shall apply only to the matters and time periods  specifically  set
forth in this Amendment.  Without limiting the generality of the foregoing, this
waiver  shall not apply to any future  failure by  Borrower  to comply  with the
terms of the Loan Agreement referenced above or any other term therein.

      2. TANGIBLE NET WORTH. This first paragraph of Section 8.1 of the Schedule
is hereby amended in full and restated as follows:

<PAGE>


            "TANGIBLE  NET WORTH:  As of the calendar  quarter  ending March 31,
      1999,  Borrower's Tangible Net Worth shall not be less than $9,800,000 and
      as of the calendar quarter ending June 30, 1999 and thereafter, Borrower's
      Tangible Net Worth shall be not less than $9,000,000.  Compliance with the
      Tangible Net Worth requirements under this Section 8.1 shall be determined
      on a  quarterly  basis.  Coast  reserves  the  right to  increase,  in its
      discretion, the Tangible Net Worth amounts required under this Section 8.1
      upon Borrower receiving additional capital contributions."

      3.  TERMINATION FEE. Section 9.2 of the Schedule is hereby amended in full
and restated as follows:

            "An amount equal to three percent (3%) of the Maximum  Dollar Amount
      or Increased  Maximum,  as  applicable  (as defined in the  Schedule),  if
      termination occurs before the Maturity Date."

      4.  MATURITY  DATE.  Section 9.2 under Section 9 of the Schedule is hereby
amended in full and restated as follows:

            "May 31, 2001,  subject to automatic  renewal as provided in Section
      9.1 of the Agreement,  and early termination as provided in Section 9.2 of
      the Agreement."

      5.  CONDITIONS.   The  effectiveness  of  this  Amendment  is  subject  to
Borrower's  execution  and  delivery  to Coast a warrant  in form and  substance
satisfactory  to Coast for 50,000  shares of common  stock of  Borrower  with an
exercise price of $2 per share and an exercise period of five years.

      6.  REAFFIRMATION.  Except  as  modified  by the  terms  herein,  the Loan
Agreement and the other Loan Documents remain in full force and effect. If there
is any conflict between the terms and provisions of this Amendment and the terms
and provisions of the Loan Agreement or the other Loan Documents,  the terms and
provisions of this Amendment shall govern.

      7. ACCOMMODATION FEES. In addition to all other fees and charges, Borrower
hereby  agrees to pay coast an  accommodation  fee of $10,000,  fully earned and
payable on the date hereof.

      8.   COUNTERPARTS.   This  Amendment  may  be  executed  in  one  or  more
counterparts,  each of  which  shall  be  deemed  an  original  but all of which
together shall constitute one and the same instrument.

      9.  GOVERNING  LAW.  This  Amendment  shall be governed  by and  construed
according to the laws of the State of California.

      10.  ATTORNEYS'  FEES;  COSTS.  Borrower  agrees to pay,  on  demand,  all
attorneys'  fees  and  costs  incurred  in  connection  with  the   negotiation,
documentation and execution of this Amendment. If any legal action or proceeding
shall be commenced at any time by any party to this Amendment in connection with
its  interpretation  or  enforcement,  the  prevailing  party or parties in such
action or  proceeding  shall be  entitled  to  reimbursement  of its  reasonable

                                       2

<PAGE>

attorneys'  fees and costs in  connection  therewith,  in  addition  to al other
relief to which the prevailing party or parties may be entitled.

      11. JURY TRIAL  WAIVER.  BORROWER AND COAST EACH WAIVE ALL RIGHTS TO TRIAL
BY JURY IN ANY ACTION OR  PROCEEDING  INSTITUTED  BY EITHER OR THEM  AGAINST THE
OTHER  WHICH  PERTAINS  DIRECTLY  OR  INDIRECTLY  TO THE  LOAN  DOCUMENTS,  THIS
AMENDMENT,  THE  OBLIGATIONS,  THE COLLATERAL,  ANY ALLEGED  TORTIOUS CONDUCT BY
BORROWER  OR COAST,  OR, IN ANY WAY,  DIRECTLY OR  INDIRECTLY,  ARISES OUT OF OR
RELATES TO THE RELATIONSHIP BETWEEN BORROWER AND COAST.
