OVERVIEW

         Sync Research, Inc. ("Sync" or the "Company") develops, manufactures,
markets, supports and sells wide-area network ("WAN") access and management
products and services designed to economically and reliably support business
critical applications across carrier provided packetized transmission services,
such as frame relay.

         As data bandwidth requirements increase, telecommunications service
providers, traditionally carriers, have implemented frame relay data services in
an effort to develop new revenue sources and improve competitiveness. Frame
relay, a low-latency, frame-switched WAN protocol, has experienced rapid growth
due to its speed and economy, stability, its deployment flexibility, and its
ability to combine incompatible "protocols," such as International Business
Machines Corporation ("IBM") mainframe Systems Network Architecture ("SNA") and
client/server Transmission Control Protocol/Internet Protocol ("TCP/IP"), onto a
single telecommunications circuit. Frame relay represents a cost-effective and
stable technology, that provides a smooth migration to asynchronous transfer
mode ("ATM") and other broadband services generally used in the backbone of many
of these service providers.

         The Company's strategy is to produce highly reliable and value-added
network access devices and management software applications that are engineered
to support mission-critical applications over frame relay and other digital
services at the lowest possible overall cost of ownership. The Company's
FrameNode-TM- line of frame relay access devices ("FRADs") and frame relay
access routers converge business critical SNA, IP/IPX and voice/fax branch
applications across frame relay. Sync's circuit management solutions consists of
WAN probes and application software that improve the availability and
performance of frame relay networks by providing extensive problem isolation and
troubleshooting capabilities and proactive performance and service-level
management. Sync's TyLink-Registered Trademark- line of digital transmission
products including data service units and channel service units ("DSU/CSU") and
Integrated Services Digital Network ("ISDN") termination products, are the basic
elements that provide low cost connectivity to a digital WAN.

         Today, many mainframe or similarly hosted data networks use expensive
leased lines to connect remote sites to central computing facilities or data
centers. Due to favorable carrier pricing and technical suitability, frame relay
is a less expensive, more efficient, direct substitute for such traditional
leased line connections and due to its maturity, is very stable as compared to
other technology based alternatives, including the internet or other IP based
services.

         Sync follows a sales strategy relying primarily on a direct sales force
and leveraging resellers, distributors, OEM partners and a number of Regional
Bell Operating Companies ("RBOCs") and Interexchange Carriers ("IXCs") as
delivery channels for its products. Current partners include, AT&T, MCI WorldCom
("MCI"), Electronic Data Systems, Unisys and Diebold. The Company believes that
its relationships provide sufficient alternative channels of fulfillment to
serve the needs of middle and upper market customers. The Company utilizes a
distribution and value-added reseller ("VAR") channel and will utilize the
internet as the primary distribution channels for its digital transmission
products.

         Sync does not have any dedicated international sales offices, however,
the Company sells its products through partners and resellers located in Europe
including Germany, France, UK and Ireland and in


                                       2

the Pacific Rim.

INDUSTRY BACKGROUND

SNA FOR BUSINESS CRITICAL APPLICATIONS
         Historically, organizations have predominantly performed their
business-critical data processing predominantly on hierarchical, centralized
computer systems, mainly IBM mainframe or similar systems. These
transaction-oriented data processing applications have traditionally supported
such critical functions as branch banking, credit transactions, retail
point-of-sale transactions, inventory management and airline reservations.
Wide-area networks have been built to provide access to these applications from
geographically-dispersed branch offices in a "hub and spoke" model, in which as
many as several thousand remote sites are connected to one or two data
processing centers.

         The critical nature of these business applications requires that
host-based systems deliver high availability with efficient and predictable
response times. IBM's SNA was designed and developed specifically to deliver
these benefits to remote terminals communicating across the current wide-area
network infrastructures, primarily leased lines. SNA has been widely deployed as
a network architecture for corporate wide-area networks since the late 1970s.

EMERGENCE OF IP AND CLIENT/SERVER COMPUTING
         In the late 1980s, "client/server" computing emerged, expanding
capabilities of software applications and ease of local interconnection through
local area networks ("LANs"). To facilitate support, scalability and security,
client/server networks are being implemented by corporations in topologies that
parallel the traditional leased-line hub and spoke model of the mainframe SNA
network. In addition, as users increasingly demand higher bandwidth, savings and
quality, carriers and service providers are rolling out new packet based voice
and data services, including Asynchronous Digital Subscriber Line (ADSL), etc.

OUTSOURCING OF NETWORK SERVICES

         Continuing deregulation and reformation within the worldwide
telecommunications market has resulted in a dramatic increase in the number of
carriers, service providers and other companies that outsource networking and
telecommunications support and services. In order to differentiate their
services, these "Service Providers" have deployed new data transport networks
based on packet and cell switched technologies; specifically frame relay,
Internet Protocol ("IP"), ATM and ADSL. Many end user organizations ("End
Users") have found these services to be cost-effective alternatives to private
leased line networks and have migrated all or part of their WAN infrastructures
including the planning, provisioning and management of their networks to their
Service Provider. These services often bundle telecommunications services with
the components necessary to connect customer sites to the network.

         The shift from leased lines to these services has created a number of
challenges for End Users and Service Providers alike. Since a significant
portion of their WAN infrastructure is now controlled and managed by their
Service Providers, End Users have diminished visibility and control of
mission-critical applications that traverse the public switched virtual network
(PSVN). In turn, Service Providers have increased responsibility for end user
application performance and higher service level commitments, especially in
connection with managed network services offerings.

THE SYNC SOLUTION

         Sync is a provider of WAN access, internetworking and management
products and related services that enable business-critical SNA and
client/server applications to be safely deployed over frame relay or other
packetized transmission services. Sync's products allow organizations to
leverage the performance, utility and cost advantages of these networks, while
maintaining the robustness, reliability and responsiveness of SNA and preserving
the sizable investment in legacy SNA applications, equipment, management
automation, diagnostic tools and staff training.


                                       3

PRODUCTS

         Sync's current product offerings have focused almost exclusively on the
growing frame relay marketplace. The Company's product portfolio targets three
distinct frame relay market related opportunities. Combined, the products offer
a broad single vendor solution for deployment and support of mission-critical
applications over frame relay.

ACCESS INTERNETWORKING SOLUTIONS

         The FrameNode-Registered Trademark- FRADs and frame relay access
routers reduce duplication in networks and recurring telecommunications costs by
converging SNA, legacy and client/server (IP/IPX) branch applications across a
frame relay WAN using a single access trunk. Sync FrameNodes-Registered
Trademark- successfully combine deterministic SNA transactions with bursty and
bandwidth-demanding client/server transmissions through a traffic prioritization
and bandwidth allocation capability.

         Sync provides a broad range of serial-to-LAN conversion products under
the ConversionNode-TM- product name. The ConversionNode-TM- enables SNA and
other legacy serial controllers to interoperate over router-based internetworks
by providing serial-to-LAN conversion. It supports a wide-array of legacy
controllers, including SNA, asynchronous BSC3270 and BSC/RJE.

         A number of large IBM-centric customers, such as Bear Sterns, First
Union Corporation ("First Union"), Electronic Data Systems, Experian, and VISA
International, have selected Sync's frame relay solutions.

CIRCUIT MANAGEMENT SOLUTIONS

         Sync's circuit management technology consists of a series of WAN
monitoring probes and graphical applications. Together, these components allow
End Users to improve network availability and performance and reduce network
operating costs by enhancing problem isolation, identification and
troubleshooting and providing performance and service-level management
capabilities.

DIGITAL TRANSMISSION SOLUTIONS

         Sync's TyLink-Registered Trademark- brand digital transmission products
support a wide range of digital access applications, including low-speed
56/64Kbps to high-speed T1/E1 models for leased line connectivity; and data,
voice and video integration on a single T1 trunk. The 7400 Series WAN Champion
is a high-capacity chassis system that can support up to 32 T1 interfaces. Its
port density and price/performance make it ideal for large-scale T1 termination
applications.

PRODUCT STRATEGY

         Sync has developed a multifaceted product strategy that the Company
believes addresses many of the issues that are important to successful
deployment of frame relay (and IP) connectivity: access circuit and
service-level management, and high-speed digital transmission. The Company is
focusing its new product development efforts on creating new product
capabilities in these three areas. During 1999, the Company released its 4300
and 3700 families of integrated frame relay access products, which combine the
feature and functions of its frame relay access products, circuit management and
digital transmission products with alternative ISDN and Async point-to-point
(PPP) backup capabilities into one combined solution. The Company believes this
product provides a cost-effective solution that enhances high availability
through alternative bandwidth functionality. Going forward, Sync plans to
continue to leverage its technology strengths through the development of
products that support for higher speeds and increase its capabilities in
supporting Internet Protocol based applications. The Company expects that the
first of these new products will begin to become available to the general market
during mid 2000. However, there can be no assurance that the Company will be
able to introduce these new products on a timely basis, if at all, or that these
products will gain market acceptance. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations-Risk Factors-Rapid
Technological Change and New Products."

CUSTOMERS AND MARKETS


                                       4
<PAGE>


         Sync's three core WAN technologies: access internetworking, circuit
management and digital transmission are targeted at two macro markets:
enterprise middle market end user customers and service providers serving such
customers.

ENTERPRISE END USER CUSTOMERS

         Sync's strategy is to provide a comprehensive product solution for
safely migrating mission-critical SNA and IP/IPX applications to frame relay and
other WAN technologies. In addition, the Company offers a broad range of
services to complement its products, including network design consulting, remote
network monitoring, onsite maintenance and technical assistance. The Company
believes that advantages to its customers include improved network reliability,
improved efficiencies in circuit and bandwidth utilization, and reduced capital,
telecommunications and operating costs. Sync has been successful in winning
several large end-user customers, however, the Company's primary focus is at the
AS400 enterprise user and middle market companies with 25 to 500 branch sites.
Many of these companies host their business critical applications on a
centralized basis in a leased line environment and can benefit from Sync's
solutions to provide a cohesive convergence of SNA and IP applications across
the same network. In addition, the Company believes that the larger
telecommunications equipment companies do not adequately serve these mid-sized
enterprises.

SERVICE PROVIDERS

         The FrameNode-Registered Trademark- is also designed to be an effective
customer premises equipment (CPE) solution for managed service offerings. In
addition to its broad support for SNA, IP/IPX and certain legacy protocols, it
includes extensive end-to-end network management capabilities facilitate more
reliable and consistent service to customers, improved efficiency in circuit and
bandwidth provisioning, and reduced capital and operating costs for service
providers.

         While enterprise customers view frame relay as a cost-effective vehicle
for converging remote SNA and IP/IPX applications, Sync believes they will
continue to demand the stability, resiliency and the management-rich attributes
of their leased line networks. Sync's circuit management technology provides
customers and service providers with the management capabilities necessary to
maximize network performance and availability requirements.

CUSTOMER BASE

   The Company's products are used in a wide variety of industries worldwide by
both End Users and Service Providers. The Company has been in, but not limited
to, the banking and financial services; credit and transaction processing;
manufacturing and industrial; insurance; retail and network; and application
outsourcing industries. Sync's customer base includes but is not limited to,
First Union Corporation, Wells Fargo, Visa International, First Data Resources,
McJunkin Corporation, Piedmont Natural Gas, GEICO Insurance; Experian,
Electronics Data Systems Corporation (EDS), Korea Telecom, and Rhodes/Helig
Myers.

SALES AND PARTNER CHANNELS

         The Company follows a sales strategy relying primarily on a U.S. based
direct sales force and leveraging resellers, distributors, and a number of
Service Providers as delivery channels for its products, including several
partners serving the international market. The Company utilizes a distribution
and value-added reseller ("VAR") channel and will utilize the internet as the
primary distribution channels for its digital transmission products. The Company
has from time to time entered into OEM relationships with selected
internetworking companies and will continue to develop such relationships as
appropriate.

DIRECT SALES

         Sync's sales and marketing strategy focuses on developing relationships
with end-user middle market enterprises through its direct sales organization to
promote the Company's products and drive demand for Sync products and support
channel partners. The primary roles of the Company's sales force are (i) to
assist end user customers in addressing complex network problems; (ii) to
differentiate the


                                       5
<PAGE>


features and capabilities of the Company's products from competitive
offerings; and (iii) provide support to channel partners as fulfillment
channels in meeting the needs of end-user customers. The Company believes
that its investment in direct sales enables the Company to monitor changing
customer requirements. As of December 31, 1999, the Company had 12 domestic
field sales and support personnel currently operating out of locations in 8
states. First Union Corporation, a direct sales customer, represented $1.8
million or 9.8% in 1999, $4.6 million or 18.5% in 1998, $1.5 million or 6.5%
in 1997of the Company's net revenues.

CHANNEL PARTNERS AND OTHER RESELLERS

         The Company's indirect sales and marketing strategy focuses on
establishing channel partnerships with selected, leading networking companies
and carriers that serve the AS400 and/or middle market enterprises. Sync works
with its channel partners in various activities, including joint sales calls,
field training and support and custom product development. The Company currently
maintains marketing and sales arrangements with Service Providers such as
Sprint, MCI, Ameritech, EDS, Lucent Technologies and Datacomm Systems and
various distributors and VAR's.

         In general, the Company's resale agreements with its channel partners
and other resellers (i) have terms ranging from one to five years, subject to
renewal, (ii) do not restrict the sale of products that compete with those of
the Company, (iii) provide for discounts based on expected or actual volumes of
products purchased or resold by the channel partner in a given period, (iv) do
not require minimum purchases, (v) provide for worldwide distribution rights,
(vi) prohibit product distribution by the Company through certain categories of
third parties under certain conditions, (vii) can be terminated by the reseller,
under certain conditions, with limited notice and with little or no penalty, and
(viii) provide manufacturing rights and access to source code upon the
occurrence of specified conditions or defaults.

         The loss of one or more of the Company's channel partners or other
resellers could have a material adverse effect on the Company's business,
operating results and financial condition. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations-Risk
Factors-Dependence on Channel Partners and Other Resellers" and "Intense
Competition."


INTERNATIONAL SALES

         Sales to customers outside of the United States accounted for
approximately $2.4 million, $1.7 million and $4.5 million, or 13.2%, 6.9% and
19.1% of the Company's net revenues in 1999, 1998 and 1997, respectively. The
Company targets international sales on an opportunistic basis and has
historically sold products internationally through partners and resellers. The
Company will continue to work with select partners and resellers to generate
sales in the European and Asian markets. At this time, international sales are
expected to continue to represent a small portion of the Company's sales.

         The Company does not have any dedicated international sales offices,
however, the Company sells its products through partners and resellers located
in Europe including Germany, France, UK, and Ireland, and in the Pacific Rim.

         Certain business risks are inherent in international transactions. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations-Risk Factors-Dependence on and Risks Associated with International
Sales."

CUSTOMER SERVICE

         The Company installs, maintains and supports products in the United
States and in selected International locations with the Company's service and
support personnel and through contracted service providers. The Company's
resellers generally provide installation, maintenance and support services to
their customers, with the Company providing backup support. Sync employs systems
engineers to deliver network consulting services and assist End Users with
pre-sales and post-sales support. As a result, the Company believes that these
systems engineers are able to provide valuable input to the product development
process based on their experience in the field. The Company also supports
customers and


                                       6
<PAGE>


sales personnel by providing remote telephone through its technical
assistance centers in Irvine, California and Norton, Massachusetts. Through a
digital dial-up network connection or a modem connection to the customer's
system the Company's representatives remotely analyze and correct software,
installation and configuration problems. The Company also offers on-site
installation, technical assistance, consulting and repair services for fixed
fees. The Company's customers may select among various levels of maintenance
options. In certain cases the Company subcontracts with one of its
third-party service providers for the provision of onsite installation and
maintenance services. Sync provides its direct end user customers with a
twelve to sixty month warranty, which commences on product shipment.

RESEARCH AND DEVELOPMENT

         The Company's success will depend to a substantial degree upon its
ability to develop and introduce in a timely fashion enhancements to its
existing products and new products that meet changing customer requirements and
emerging industry standards. The Company intends to continue to make substantial
investments in product and technology development. The Company monitors changing
customer needs and intends to support industry standards and migrate to new
wide-area networking protocols.

         The Company's research and development expenditures aggregated $5.5
million, $7.4 million and $7.2 million in 1999, 1998 and 1997, respectively. At
December 31, 1999, 41 full-time employees were engaged in research and product
development. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations-Risk Factors-Dependence on Key Personnel" and "Results
of Operations."

         The Company is focusing its new product development efforts on creating
new product capabilities. During 1999, the Company released its 4300 and 3700
families of integrated frame relay access products, which combine the feature
and functions of its frame relay access products, circuit management and digital
transmission products with alternative ISDN and Async PPP backup capabilities
into one combined solution. The Company believes this product provides a
cost-effective solution that enhances high availability through alternative
bandwidth functionality. Going forward, Sync plans to continue to leverage its
technology strengths through the development of products that support higher
speeds and increase its capabilities in supporting Internet Protocol based
applications. The Company expects that the first of these new products will
begin to become available to the general market during mid-2000. However, no
assurances can be given that the Company will be able to introduce any or all of
these products on a timely basis, if at all. Also, there can be no assurance
that the Company will be able to identify, develop, manufacture, market or
support new products successfully, that such new products will gain market
acceptance or that the Company will be able to respond effectively to
technological changes, emerging industry standards, including new PSVN services,
or product announcements by competitors. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations"-Risk Factors-"Rapid
Technological Change and New Products" and "Product Errors."

MANUFACTURING

         Sync's operational strategy continues to emphasize outsourcing of
board-level manufacturing to reduce costs and to provide flexibility in meeting
market demand. The Company's manufacturing operations consist primarily of
materials planning and procurement, light assembly, system integration, testing
and quality assurance. The Company designs substantially all of the hardware
subassemblies for its products and has entered into arrangements with contract
manufacturers to outsource substantial portions of its subassembly procurement,
assembly and system test operations.

         There can be no assurance that these independent contract manufacturers
will be able to meet the Company's future requirements for manufactured products
or that such independent contract manufacturers will not experience quality
problems in manufacturing the Company's products. The inability of the Company's
contract manufacturers to provide the Company with adequate supplies of high
quality products could have a material adverse effect upon the Company's
business, operating results and financial condition. The loss of any of the
Company's contract manufacturers could cause a delay in Sync's ability to
fulfill orders while the Company identifies a replacement manufacturer. Such an
event could have a material adverse


                                       7
<PAGE>


effect on the Company's business, operating results and financial condition.

         The Company uses a rolling three-month forecast based on anticipated
product orders to determine its general materials and manufacturing staffing
requirements. Lead times for materials and components ordered by the Company
vary significantly, and depend on factors such as the specific supplier,
contract terms and demand for a component at a given time. Currently, the
Company acquires materials and completes certain standard subassemblies based on
the Company's forecast. Upon receipt of firm orders from customers, the Company
assembles fully-configured systems and subjects them to a number of tests before
shipment. The Company's manufacturing procedures are designed to assure rapid
response to customer orders, but may in certain instances create a risk of
excess or inadequate inventory if orders do not match forecasts. Any
manufacturing delays, excess manufacturing capacity or inventories, or inability
to increase manufacturing capacity, if required, could have a material adverse
effect on the Company's business, operating results and financial condition. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations-Risk Factors-Dependence on Contract Manufacturers," and "Dependence
on Suppliers."

         Although the Company generally uses standard parts and components for
its products, certain key components are currently purchased only from single or
limited sources. At present, single-sourced components include programmable
integrated circuits, selected other integrated circuits and cables,
custom-molded plastics and custom-tooled sheet metal and limited-sourced
components, including flash memories, dynamic random access memory (DRAM),
printed circuit boards and selected integrated circuits. The Company generally
relies upon contract manufacturers to buy component parts that are incorporated
into board assemblies. The Company directly buys final assembly parts, such as
plastics and metal covers, cables and other parts used in final configurations.
The Company generally does not have long-term agreements with any of these
single or limited sources of supply. Any interruption in the supply of any of
these components, or the inability of the Company to procure these components
from alternate sources at acceptable prices and within a reasonable time, could
have a material adverse effect upon the Company's business, operating results
and financial condition. From time to time the Company has experienced shortages
of certain components and has paid above-market prices to acquire such
components on an accelerated basis or has experienced delays in fulfilling
orders while waiting to receive the necessary components. Such shortages may
occur in the future and could have a material adverse effect on the Company's
business, operating results and financial condition.

         The Company's has obtained ISO 9001 certification for all of its
facilities. The Company's inability to maintain certification of all of its
facilities could have a material adverse effect on the Company's business,
operating results and financial condition.

COMPETITION

         The market for communications products is intensely competitive and
subject to rapid technological change and emerging industry standards. The
Company's current competitors include internetworking companies such as Cisco
Systems, Inc. ("Cisco") and Nortel, FRAD providers such as Hypercom Network
Systems ("Hypercom"), Motorola Information Systems Group ("Motorola ISG"), and
Cabletron Systems, Inc. ("Cabletron"), and circuit management and digital
transmission providers such as Visual Networks, Inc. ("Visual Networks"),
NetScout, Digital Link Corporation ("Digital Link"), Racal Datacom, Inc., AT&T
Paradyne ("Paradyne") and Adtran, Inc. ("Adtran"), among others. Potential
competitors include other internetworking and WAN access and transmission
companies, frame relay switch providers, the Company's channel partners. Certain
of these companies have announced products and intentions to enter the frame
relay access or circuit management market.

         Many of the Company's current and potential competitors have longer
operating histories and greater financial, technical, sales, marketing and other
resources, as well as greater name recognition and a larger customer base, than
the Company. As a result, they may be able to respond more quickly to new or
emerging technologies and changes in customer requirements or may be able to
devote greater resources to the development, promotion, sale and support of
their products than the Company. Many also have long-standing customer
relationships with large enterprises that are part of the Company's target
market, and


                                       8
<PAGE>


these relationships may make it more difficult to complete sales of the
Company's products to these enterprises. Further, certain of the Company's
channel partners have in the past developed competitive products and
terminated their relationships with the Company, and such developments could
occur in the future. As a consequence of all these factors, the Company
expects increased competition, particularly in the frame relay market.
Increased competition could result in significant price competition, reduced
profit margins or loss of market share, any of which could have a material
adverse effect on the Company's business, operating results and financial
condition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations-Risk Factors-Intense Competition."

         Sync believes that the principal competitive factors in its market are
expertise and familiarity with SNA networks and protocols, expertise and
knowledge with high capacity mission-critical network issues and solutions,
product performance, features, functionality and reliability, price, overall
cost of ownership, timeliness of new product introductions, adoption of emerging
industry standards, service, support, size and installed base. The Company
believes that it generally is competitive with respect to most of these factors.
However, there can be no assurance that the Company will be able to compete
successfully in the future.

PROPRIETARY RIGHTS

         The Company's future success depends, in part, upon its proprietary
technology. The Company does not hold any patents and currently relies on a
combination of contractual rights, trade secrets and copyright laws to establish
and protect its proprietary rights in its products. There can be no assurance
that the steps taken by the Company to protect its intellectual property will be
adequate to prevent misappropriation of its technology or that the Company's
competitors will not independently develop technologies that are substantially
equivalent or superior to the Company's technology. In the event that protective
measures are not successful, the Company's business, operating results and
financial condition could be materially and adversely affected. In addition, the
laws of some foreign countries do not protect the Company's proprietary rights
to the same extent as do the laws of the United States. The Company is also
subject to the risk of adverse claims and litigation alleging infringement of
intellectual property rights of others. There can be no assurance that third
parties will not assert infringement claims in the future with respect to the
Company's current or future products or that any such claims will not require
the Company to enter into license arrangements or result in litigation,
regardless of the merits of such claims. No assurance can be given that any
necessary licenses will be available or that, if available, such licenses can be
obtained on commercially reasonable terms. Should litigation with respect to any
such claims commence, such litigation could be extremely expensive and time
consuming and could have a material adverse effect on the Company's business,
operating results and financial condition, regardless of the outcome of such
litigation. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations-Risk Factors-Dependence on Proprietary Technology."

EMPLOYEES

         As of December 31, 1999, the Company employed 103 persons, including 41
in engineering, 21 in sales and marketing, 29 in operations and 12 in finance
and administration. There can be no assurance that the Company will be
successful in retaining its key employees. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations-Results of Operations"
and "Risk Factors-Dependence on Key Personnel."

ITEM 2.  PROPERTIES

         The Company leases approximately 24,000 square feet of space for the
Company's headquarters facility in Irvine, California. The current lease on the
Irvine facility expires in August 2004. In addition, the Company's Tylink
operation leases an industrial building in Norton, Massachusetts. This building
lease expires at the end of July 2002. The Company also has sales and support
offices in 8 other states.

ITEM 3.  LEGAL PROCEEDINGS

         On November 5, 1997, an action entitled Dalarne Partners, Ltd. Vs
Sync Research, Inc., et al., No. SACV97-877 AHS (Eex) was filed against the
Company and certain of its directors and officers. The action was filed in
the U.S. District Court for the Central Division of California, Southern
Division.


                                       9

The action purported to be a class action lawsuit brought on behalf of
purchasers of the Company's common stock during the period from November 18,
1996 through March 20, 1997. The complaint asserted claims for violation of
the Securities Exchange Act of 1934. On January 28, 2000 the court dismissed
the complaint with prejudice. Plaintiffs have appealed the dismissal. There
is no date scheduled for the hearing on the appeal

         There are no other material legal proceedings to which the Company is a
party or to which any of its properties are subject. No material legal
proceedings were terminated in the year ended December 31, 1999.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

OVERVIEW

         Sync develops and sells frame relay access devices (FRADs), circuit
management probe products, digital transmission devices and supporting
software. The Company follows a sales strategy relying primarily on a direct
sales force and leveraging resellers, distributors, and carriers as delivery
channels for its products. Current partners include AT&T, MCI, Electronic
Data Systems, Unisys and Diebold.

         In 1998 and 1997, the Company implemented various expense reduction
programs with the goal of enabling the Company to achieve profitability at
lower revenue levels. However, there can be no assurance that its efforts to
implement expense reductions will enable it to become profitable at lower
revenue levels, if at all. Also, there can be no assurance that the Company's
products will achieve significant market penetration, either through its
channel partners and other resellers or its direct sales force, or that the
Company will successfully introduce new and enhanced products or compete
effectively in its market.

RISK FACTORS

         The Company desires to take advantage of the "safe harbor"
provisions of the Private Securities Litigation Reform Act of 1995.
Specifically, the Company wishes to alert readers that, except for the
historical information contained herein, the following discussion under
"Results of Operations," "Inflation," "Year 2000 Compliance" and "Liquidity
and Capital Resources" constitutes forward-looking statements that are
dependent on certain risks and uncertainties which may cause actual results
to differ materially from those expressed in any forward-looking statements
made by or on behalf of the Company. The following is a description of
certain of the major risks and uncertainties.

HISTORY OF LOSSES; SIGNIFICANT FLUCTUATIONS IN OPERATING RESULTS; UNCERTAIN
PROFITABILITY

         The Company has experienced operating losses since inception, with,
in recent years, operating losses of, $4.7 million in 1999, $16.3 million in
1998 and $18.0 million in 1997. As of December 31, 1999, the Company had an
accumulated deficit of approximately $58.7 million. The Company has
experienced, and may in the future experience, significant fluctuations in
revenues and operating results from quarter to quarter and from year to year
due to a combination of factors. Factors that have in the past caused, or may
in the future cause, the Company's revenues and operating results to vary
significantly from period to period include: the timing of significant
orders; the relatively long length of the sales cycles for certain of the
Company's products; the market conditions in the networking industry; the
timing of capital expenditures by the Company's target market customers;
competition and pricing in the industry; the Company's success in developing,
introducing and shipping new products; new product introductions by the
Company's competitors; production or quality problems; changes in material
costs; disruption in sources of supply; changes in foreign currency exchange
rates; and general economic conditions. In addition, revenues and gross
margins may fluctuate due to the mix of distribution channels employed and
the mix of products sold. For example, the Company generally realizes a
higher gross margin on direct sales than on sales through its channel
partners and other resellers. Accordingly, if channel partners and other
resellers account for a large percentage of the Company's net revenues, gross
profit as a percentage of net revenues may decline.

         The Company's future revenues are difficult to predict. Revenues and
operating results in any quarter depend on the volume and timing of, and the
ability to fulfill, orders received within the quarter. Sales of the Company's
products typically involve a sales cycle of several months to over a year from
the point of initial customer contact until receipt of the first system order,
and, in addition, the Company has in the past encountered, and may in the future
encounter, delays between initial orders and network-wide deployment. There can
be no assurance that average sales cycles will not increase in future periods.
During the past year, the Company has shifted its efforts from a focus utilizing
channel partners to one focused more on a direct sales model while utilizing
channel partners for strategic opportunities and fulfillment. Accordingly, the
Company's revenues in any period are highly dependent upon the sales efforts and
success of the Company's direct sales force and those channel partners upon
which it relies. There can be no assurance

                                        13
<PAGE>

that the Company's channel partners and other resellers will give a high
priority to the marketing of the Company's products as compared to
competitive products or solutions or that the Company's channel partners and
other resellers will continue to offer the Company's products. In addition,
the Company has shifted its focus from large corporate Fortune 100
enterprises to the middle market enterprise; those companies with 50 to 500
remote locations. There can be no assurance that the middle market enterprise
prospect customers will select the Company's products as compared to
alternative product offerings provided by other vendors.Significant portions
of the Company's expenses are relatively fixed. If sales are below
expectations in any given period, the adverse effect of a shortfall in sales
on the Company's operating results may be magnified by the Company's
inability to adjust spending to compensate for such shortfall. The Company
has in the past and may in the future reduce prices or increase spending to
respond to competition or to pursue new product or market opportunities.
Accordingly, there can be no assurance that the Company will be able to
attain or sustain profitability on a quarterly or an annual basis. In
addition, if the Company's operating results fall below the expectations of
public market analysts and investors, the price of the Company's common stock
would likely be materially and adversely affected.

UNCERTAIN MARKET FOR FRAME RELAY FOR MISSION-CRITICAL APPLICATIONS

         During 1999, 1998 and 1997, sales of frame relay access products,
which enable multiprotocol (IP, IPX and SNA) internet-working over frame
relay, represented approximately 37.7%, 49.2% and 43.1%, respectively, of the
Company's net revenues. The market for SNA-over-frame relay products is
maturing. The success of the Company and its channel partners in generating
significant sales of frame relay access products will depend in part on their
ability to educate end users about the benefits of the Company's technology
and convince end users to switch their mission-critical applications to frame
relay rather than remaining on leased line networks or selecting newer and/or
alternative technologies. In addition, broad acceptance of frame relay
services will also depend upon the tariffs for such services, which are
determined by carriers. If the tariff structure for dedicated leased lines
becomes more favorable relative to tariffs for a comparable network utilizing
frame relay, the market for frame relay networking products could be
adversely affected. There can be no assurance that the market will adopt
frame relay for mission-critical applications to any significant extent. The
failure of such adoption to occur could have a material adverse effect on the
Company's business, operating results and financial condition. The Company's
frame relay access products are targeted at the large installed base of IBM
customers utilizing SNA networks. IBM has sold, in the past, the Company's
FrameNode-Registered Trademark- product family under the name IBM Nways 2218.
The agreement between IBM and the Company expired in March 1999. Sales to IBM
accounted for 0.8%, 14.1% and 16.5% of the Company's net revenues in 1999,
1998 and 1997, respectively. On August 31, 1999, IBM announced its intention
to discontinue support for many of its wide area network products and in lieu
of such support entered into an arrangement with Cisco Systems to transition
its customers and prospects towards solutions provided by Cisco. The Company
has relied on IBM products, in certain circumstances, to provide support for
Sync products at the customer's data center. Due to the IBM announcement, the
Company will need to enhance its product capability to include
interoperability with products provided by vendors other than IBM. There can
be no assurance that IBM will continue to support frame relay, that IBM will
not develop or promote SNA-over-frame relay products competitive with the
Company's products, that the IBM/ Cisco relationship will not adversely
impact the Company's ability to sell its products, or that the Company will
be able to sufficiently provide for interoperability between its products and
products provided by vendors other that IBM. Any of these events could have a
material adverse effect on the Company's business, operating results and
financial condition.

 UNCERTAIN MARKET ACCEPTANCE OF THE COMPANY'S PRODUCTS; PRODUCT CONCENTRATION

         The Company currently derives substantially all of its revenues from
its frame relay access, circuit management, transmission and related services
and expects that revenues from these products will continue to account for
substantially all of its revenues for the foreseeable future. Broad market
acceptance of, and continuing demand for, these products, is, therefore,
critical to the Company's future success. Factors that may affect the market
acceptance of the Company's products include the extent to which frame relay
is adopted for mission-critical applications, the availability and price of
competing products and technologies, services or pricing relevant to the
Company, the success of the sales efforts of the Company and its resellers
and tariff rates for carrier services. Moreover, the Company's operating
history in the WAN internetworking market and its resources are limited
relative to certain of its current and potential competitors. The

                                        14
<PAGE>

Company's future performance will also depend in part on the successful
development, introduction and market acceptance of new and enhanced products.
Failure of the Company's products to achieve market acceptance could have a
material adverse effect on the Company's business, operating results and
financial condition.

DEPENDENCE ON CHANNEL PARTNERS AND OTHER RESELLERS

         The Company's channel partners and other resellers account, and are
expected to continue to account, for a relatively large percentage of the
Company's net revenues, including most of its sales outside of the United
States. Sales through channel partners and other resellers accounted for
47.1%, 62.5% and 67.0% of net revenues of the Company in 1999, 1998 and 1997,
respectively. Current partners include AT&T, MCI, Electronic Data Systems,
Unisys and Diebold. The Company has also sold its products through OEM
relationships with IBM among others. The agreement between IBM and Sync
expired in March 1999. Sales to IBM accounted for 0.8%, 14.1% and 16.5% of
the Company's net revenues for in 1999, 1998, and 1997, respectively.

         The Company's agreements with its channel partners and other
resellers do not restrict the sale of products that compete with those of the
Company. Each of the Company's channel partners or other resellers can cease
marketing the Company's products at the reseller's option, under certain
conditions, with limited notice and with little or no penalty. In addition,
these agreements generally provide for discounts based on expected or actual
volumes of products purchased or resold by the reseller in a given period, do
not require minimum purchases, prohibit distribution of certain products by
the Company through certain categories of third parties under certain
conditions and provide for manufacturing rights and access to source code
upon the occurrence of specified conditions or defaults.

         Many of the Company's channel partners and resellers offer
alternative solutions, designed by themselves or third parties and have
pre-existing relationships with current or potential competitors of the
Company. Certain of the Company's former channel partners have developed
competitive products and terminated their relationships with the Company, and
such developments could occur in the future.

         The Company generally realizes a higher gross margin on direct sales
than on sales through its channel partners and other resellers. Accordingly,
as channel partners and other resellers continue to account for a relatively
large portion of the Company's net revenues, gross profit as a percentage of
net revenues may decline.

         There can be no assurance that the Company will retain its current
channel partners or other resellers or that it will be able to recruit
additional or replacement channel partners. The loss of one or more of the
Company's channel partners or other resellers could have a material adverse
effect on the Company's business, operating results and financial condition.
In addition, there can be no assurance that the Company's channel partners
and other resellers will give priority to the marketing of the Company's
products as compared to competitive products or alternative networking
solutions or that the Company's channel partners and other resellers will
continue to offer the Company's products. Any reduction or delay in sales of
the Company's products by its channel partners and other resellers could have
a material adverse effect on the Company's business, operating results and
financial condition.

RAPID TECHNOLOGICAL CHANGE AND NEW PRODUCTS

         The market for the Company's products is characterized by rapidly
changing technology, evolving industry standards and frequent new product
introductions. The Company's success will depend to a substantial degree upon
its ability to develop and introduce in a timely fashion enhancements to its
existing products and new products that meet changing customer requirements
and emerging industry standards. The development of new, technologically
advanced products is a complex and uncertain process requiring high levels of
innovation, as well as the accurate anticipation of technological and market
trends. There can be no assurance that the Company will be able to identify,
develop, manufacture, market or support new products successfully, that such
new products will gain market acceptance or that the Company will be able to
respond effectively to technological changes, emerging industry standards or
product announcements by competitors. In addition, the Company has on
occasion experienced delays in the introduction of product

                                        15
<PAGE>

enhancements and new products. There can be no assurance that in the future
the Company will be able to introduce product enhancements or new products on
a timely basis. Further, from time to time, the Company may announce new
products, capabilities or technologies that have the potential to replace or
shorten the life cycle of the Company's existing product offerings. There can
be no assurance that announcements of product enhancements or new product
offerings will not cause customers to defer purchasing existing Company
products or cause resellers to return products to the Company. Failure to
introduce new products or product enhancements effectively and on a timely
basis, customer delays in purchasing products in anticipation of new product
introductions and any inability of the Company to respond effectively to
technological changes, emerging industry standards or product announcements
by competitors could have a material adverse effect on the Company's
business, operating results and financial condition.

PRODUCT ERRORS

         Products as complex as those offered by the Company may contain
undetected software or hardware errors. Such errors have occurred in the
past, and there can be no assurance that, despite testing by the Company and
customers, errors will not be found after commencement of commercial
shipments. Moreover, there can be no assurance that once detected, such
errors can be corrected in a timely manner, if at all. Software errors may
take several months to correct, if they can be corrected at all, and hardware
errors may take even longer to rectify. The occurrence of such software or
hardware errors, as well as any delay in correcting them, could result in the
delay or loss of market acceptance of the Company's products, additional
warranty expense, diversion of engineering and other resources from the
Company's product development efforts or the loss of credibility with the
Company's end-user customers, channel partners and other resellers, any of
which could have a material adverse effect on the Company's business,
operating results and financial condition.

INTENSE COMPETITION

         The market for communications products is intensely competitive and
subject to rapid technological change and emerging industry standards. The
Company's current competitors include internetworking companies, such as
Cisco and Nortel; FRAD providers, such as Hypercom, Motorola and Cabletron;
and circuit management and digital transmission providers such as Visual
Networks, Netscout, Digital Link, Racal, Paradyne and Adtran, among others.
Potential competitors include other internetworking and WAN access and
transmission companies, frame relay switch providers, and the Company's other
channel partners. Many of the Company's current and potential competitors
have longer operating histories and greater financial, technical, sales,
marketing and other resources, as well as greater name recognition and a
larger customer base, than does the Company. As a result, they may be able to
respond more quickly to new or emerging technologies and changes in customer
requirements or may be able to devote greater resources to the development,
promotion, sale and support of their products than the Company. Many also
have long-standing customer relationships with mid-sized and large
enterprises that are part of the Company's target market, and these
relationships may make it more difficult to complete sales of the Company's
products to these enterprises. Further, certain of the Company's former
channel partners have developed competitive products and terminated their
relationships with the Company, and such developments could occur in the
future. As a consequence of all these factors, the Company expects increased
competition which could result in significant price competition, reduced
profit margins or loss of market share and could have a material adverse
effect on the Company's business, operating results and financial condition.
There can be no assurance that the Company will be able to compete
successfully in the future.

DEPENDENCE ON CONTRACT MANUFACTURERS

         The Company's manufacturing operations consist primarily of
materials planning and procurement, light assembly, system integration,
testing and quality assurance. The Company has entered into arrangements with
contract manufacturers to outsource substantial portions of its board level
procurement, assembly and system test operations. There can be no assurance
that these independent contract manufacturers will be able to meet the
Company's future requirements for manufactured products or that such
independent contract manufacturers will not experience quality problems in
manufacturing the Company's products. The inability of the Company's contract
manufacturers to provide the Company with adequate supplies of high

                                        16
<PAGE>

quality products could have a material adverse effect upon the Company's
business, operating results and financial condition. The loss of any of the
Company's contract manufacturers could cause a delay in the Company's ability
to fulfill orders while the Company identifies a replacement manufacturer.
Such an event could have a material adverse effect on the Company's business,
operating results and financial condition.

         The Company's manufacturing procedures may in certain instances
create a risk of excess or inadequate inventory if orders do not match
forecasts. Any manufacturing delays, excess manufacturing capacity or
inventories or inability to increase manufacturing capacity, if required,
could have a material adverse effect on the Company's business, operating
results and financial condition.

DEPENDENCE ON SUPPLIERS

         Certain key components used in the manufacture of the Company's
products are currently purchased only from single or limited sources. At
present, single-sourced components include programmable integrated circuits,
selected other integrated circuits and cables, custom-molded plastics and
custom-tooled sheet metal, and limited-sourced components include flash
memories, DRAMs, printed circuit boards and selected integrated circuits. The
Company generally relies upon contract manufacturers to buy component parts
that are incorporated into board assemblies. The Company buys directly final
assembly parts, such as plastics and metal covers, cables and other parts
used in final configurations. The Company generally does not have long-term
agreements with any of these single or limited sources of supply. Any loss of
a supplier, increase in lead times, cost increases, component supply
interruption, or the inability of the Company to procure these components
from alternate sources at acceptable prices and within a reasonable time,
could have a material adverse effect upon the Company's business, operating
results and financial condition. If orders do not match forecasts, the
Company may have excess or inadequate inventory of certain materials and
components, and suppliers may demand longer lead times, higher prices or
termination of contracts. From time to time the Company has experienced
shortages of certain components and has paid above-market prices to acquire
such components on an accelerated basis or has experienced delays in
fulfilling orders while waiting to obtain the necessary components. Such
shortages may occur in the future and could have a material adverse effect on
the Company's business, operating results and financial condition.

DEPENDENCE ON AND RISKS ASSOCIATED WITH INTERNATIONAL SALES

         Sales to customers outside of the United States accounted for
approximately $2.4 million, $1.7 million and $4.5 million, or 13.2%, 6.9% and
19.1% of the Company's net revenues in 1999, 1998 and 1997 respectively. The
Company targets international sales on an opportunistic basis and has
historically sold products internationally through partners and resellers.
The Company will continue to work with select partners and resellers to
generate sales in the European and Asian markets. At this time, international
sales are expected to continue to represent a small portion of the Company's
sales.

         Failure of the Company's international partners and resellers to
market the Company's products internationally or the loss of any of these
resellers could have a material adverse effect on the Company's business,
operating results and financial condition. In addition, the Company's ability
to increase sales of its products to international end users may be limited
if the carrier services, such as frame relay, or protocols supported by the
Company's products are not widely adopted internationally. A number of
additional risks are inherent in international transactions, including
currency valuation. Company's international sales currently are U.S.
dollar-denominated. As a result, an increase in the value of the U.S. dollar
relative to foreign currencies could make the Company's products less
competitive in international markets. International sales may also be limited
or disrupted by the imposition of governmental controls, export license
requirements, restrictions on the export of critical technology, political
instability, trade restrictions and changes in tariffs. In addition, sales in
Europe and certain other parts of the world typically are adversely affected
in the third quarter of each year as many customers and end users reduce
their business activities during the summer months. These international
factors could have a material adverse effect on future sales of the Company's
products to international end users and, consequently, the Company's
business, operating results and financial condition.

                                        17

DEPENDENCE ON PROPRIETARY TECHNOLOGY

         The Company's future success depends, in part, upon its proprietary
technology. The Company does not hold any patents and currently relies on a
combination of contractual rights, trade secrets and copyright laws to
establish and protect its proprietary rights in its products. There can be no
assurance that the steps taken by the Company to protect its intellectual
property will be adequate to prevent misappropriation of its technology or
that the Company's competitors will not independently develop technologies
that are substantially equivalent or superior to the Company's technology. In
the event that protective measures are not successful, the Company's
business, operating results and financial condition could be materially and
adversely affected. In addition, the laws of some foreign countries do not
protect the Company's proprietary rights to the same extent as do the laws of
the United States. The Company is also subject to the risk of adverse claims
and litigation alleging infringement of intellectual property rights of
others. There can be no assurance that third parties will not assert
infringement claims in the future with respect to the Company's current or
future products or that any such claims will not require the Company to enter
into license arrangements or result in litigation, regardless of the merits
of such claims. No assurance can be given that any necessary licenses will be
available or that, if available, such licenses can be obtained on
commercially reasonable terms. Should litigation with respect to any such
claims commence, such litigation could be extremely expensive and
time-consuming and could have a material adverse effect on the Company's
business, operating results and financial condition regardless of the outcome
of such litigation.

TARIFF AND REGULATORY MATTERS

         Rates for public telecommunications services, including features and
capacity of such services, are governed by tariffs determined by carriers and
subject to regulatory approval. Future changes in these tariffs could have a
material effect on the Company's business. For example, should tariffs for
frame relay services increase relative to tariffs for dedicated leased lines,
the cost-effectiveness of the Company's products could be reduced, which
could have a material adverse effect on the Company's business, operating
results and financial condition. In addition, the Company's products must
meet industry standards and receive certification for connection to certain
public telecommunications networks prior to their sale. In the United States,
the Company's products must comply with various regulations defined by the
Federal Communications Commission and Underwriters Laboratories.
Internationally, the Company's products must comply with standards
established by the various European Community telecommunications authorities.
In addition, carriers require that equipment connected to their networks
comply with their own standards. Any future inability to obtain on a timely
basis or retain domestic or foreign regulatory approvals or certifications or
to comply with existing or evolving industry standards could have a material
adverse effect on the Company's business, operating results and financial
condition.

DEPENDENCE ON KEY PERSONNEL

         The Company's success depends, to a significant degree, upon the
continued contributions of its key personnel. The Company believes its future
success will also depend in large part upon its ability to attract and retain
highly skilled engineering, managerial, sales and marketing personnel.
Competition for such personnel is intense, and there can be no assurance that
the Company will be successful in attracting and retaining such personnel.
During 1999, the Company has undergone significant personnel turnover in
research and development, sales, and other functional areas and the Company
experienced significant turnover in the composition of its executive
officers. Such turnover has affected the Company's ability to successfully
develop new products and generate additional business. Two of the current
three executive officers have been officers of the Company for less than a
year. The loss of the services of any of the Company's key personnel or the
failure to attract or retain qualified personnel in the future could have a
material adverse effect on the Company's business, operating results or
financial condition.

GENERAL ECONOMIC CONDITIONS

         Demand for the Company's products depends in large part on the
overall demand for communications and networking products, which has in the
past and may in the future fluctuate significantly based on numerous factors,
including capital spending levels and general economic conditions. There can
be no assurance that the Company will not experience a decline in demand for
its products due to general economic conditions. Any such decline could have
a material adverse effect on the Company's business, operating results and
financial condition.

                                        18

VOLATILITY OF STOCK PRICE

         Factors such as announcements of technological innovations or the
introduction of new products by the Company or its competitors, as well as
market conditions in the technology sector, may have a significant effect on the
market price of the Company's common stock. Further, the stock market has
experienced volatility which has particularly affected the market prices of
equity securities of many high technology companies and which often has been
unrelated to the operating performance of such companies. These market
fluctuations may have an adverse effect on the price of the Company's common
stock.

NASDAQ STOCK LISTING

         The Company's common stock is listed and traded on The Nasdaq Stock
Market. On January 4, 1999, the Company received a letter from Nasdaq
notifying the Company that it has failed to maintain a closing bid price of
greater than $1.00 in accordance with the Nasdaq listing requirements. In
order to comply with the Nasdaq listing requirements, on June 28, 1999 the
Company implemented a 1 for 5 reverse stock split that was approved by the
Company's stockholders at the Annual Meeting on June 11, 1999. As a result of
the reverse stock split, the Company has maintained its stock price above the
$1 per share minimum level, and, accordingly, was informed by Nasdaq that it
had met the requirements for continued listing. However, there can be no
assurance that the Company will meet the minimum closing bid price or any
other Nasdaq listing requirements on an ongoing basis.

ANTI-TAKEOVER PROVISIONS

         The Company is subject to the provisions of Section 203 of the
Delaware General Corporation Law, an anti-takeover law. In addition, certain
provisions of the Company's charter documents, including provisions
eliminating cumulative voting, eliminating the ability of stockholders to
call meetings or to take actions by written consent and limiting the ability
of stockholders to raise matters at a meeting of stockholders without giving
advance notice, may have the effect of delaying or preventing a change in
control or management of the Company, which could have an adverse effect on
the market price of the Company's common stock. Certain of the Company's
stock option and purchase plans and agreements provide for assumption of such
plans, or, alternatively, immediate vesting upon a change of control or
similar event. In addition, the Company has entered into severance agreements
with its officers, pursuant to which they are entitled to defined severance
payments if they are actually or constructively terminated within specified
time periods following a change of control of the Company. The Board of
Directors has authority to issue up to 2,000,000 shares of preferred stock
and to fix the rights, preferences, privileges and restrictions, including
voting rights, of these shares without any further vote or action by the
stockholders. The rights of the holders of the common stock will be subject
to, and may be adversely affected by, the rights of the holders of any
preferred stock that may be issued in the future. The issuance of preferred
stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of making it
more difficult for a third party to acquire a majority of the outstanding
voting stock of the Company, thereby delaying, deferring or preventing a
change in control of the Company. Furthermore, such preferred stock may have
other rights, including economic rights senior to the common stock, and as a
result, the issuance of such preferred stock could have a material adverse
effect on the market value of the common stock. The Company has no present
plan to issue shares of preferred stock.

RESULTS OF OPERATIONS

         COMPARISON OF 1999 AND 1998 RESULTS

         NET REVENUES. The Company derives its revenues primarily from sales
of advanced wide-area networking products, which are recognized upon
shipment. The Company generally does not have any significant remaining
obligations upon shipment of its products. Product returns and sales
allowances are provided for at the date of sale. Service revenues from
customer maintenance fees for ongoing customer support and product updates
are recognized ratably over the term of the maintenance period, which is
typically 12 months. Service revenues for training, installation and
consulting services are recognized when the service is performed.

         Net revenues in 1999 were $18.2 million, a decrease from net
revenues of $24.7 million in 1998. Net

                                        19

</TABLE>

         The decrease in product revenues was primarily due to completion of
several large projects in 1998. The increase in service and other revenue
represents higher service revenues resulting from the emphasis in selling
support and consulting services during 1999.

         The percentage of net revenues represented by sales through channel
partners and other resellers declined to 47.1% in 1999 from 62.5% in 1998.
Sales to IBM accounted for 0.8% and 14.1% of the Company's net revenues in
1999 and 1998. The agreement between IBM and Sync expired in March 1999. The
Company expects that average selling prices may continue to decline and that
sales through channel partners and other resellers may continue to account
for a relatively large portion of net revenues; however, the mix of sales
among channel partners and other resellers may change from period to period.

         International sales accounted for 13.2% of net revenues in 1999, as
compared to 6.9% of net revenues in 1998. The increase was primarily due to
shipments for international locations of a U.S. based customer

         GROSS PROFIT. Cost of sales primarily consists of purchased
materials used in the assembly of the Company's products, fees paid to third
party subcontractors for installation and maintenance services, and
compensation paid to employees in the Company's manufacturing and service
organizations.

         Gross profit decreased to $8.2 million for 1999 compared to $8.9
million in 1998, primarily as a result of the lower revenue levels. Gross
profit as a percentage of net revenues increased to 45.4% in 1999 from 35.8%
in 1998, due primarily to lower manufacturing overhead costs and an increase
in higher margin service revenues.

         OPERATING EXPENSES. Research and development expenses primarily
consist of compensation paid to personnel, including consultants, engaged in
research and development activities, amounts paid for outside development
services, costs of materials utilized in the development of hardware
products, including product prototypes, and the depreciation and amortization
of equipment and tools utilized in the research and development process.
Research and development expenses decreased to $5.5 million in 1999, from
$7.4 million in 1998 due to the Company's cost reduction efforts and
unstaffed development positions resulting from employee turnover.

         Selling and marketing expenses consist primarily of base and
incentive compensation paid to sales and marketing personnel, travel and
related expenses, and costs associated with promotional and trade show
activities. Selling and marketing expenses decreased to $5.1 million in 1999
from $11.9 million in 1998 due primarily to the Company's cost reduction
efforts and unstaffed sales positions resulting from employee turnover.

         General and administrative expenses consist primarily of
compensation paid to corporate and administrative personnel, payments to
consultants and professional service providers, and public company related
costs. General and administrative expenses decreased to $2.3 million in 1999
from $3.0 million in 1998. The decrease in general and administrative
expenses was primarily due to the Company's cost reduction efforts.

         During the fourth quarter of fiscal 1998, the Company implemented
additional expense reduction programs to reduce its overall cost structure
and, as a result, recognized a $2.9 million non-recurring charge consisting
of severance and related headcount reduction costs, idle and excess facility
charges and write-offs of assets no longer in use due to the reduction
efforts. The activity of the Company's cost reduction efforts are summarized
as follows (in thousands):

         The Company completed substantially all of its cost reduction
measures during fiscal 1999. The Company will continue to evaluate and may
adjust its organization and cost structure in the future.

         Net interest income was $0.4 million in 1999, as compared to $0.9
million in 1998. The decrease in interest income was primarily due to the
Company's lower cash balances resulting from the use of cash to fund the
Company's operating activities.

         INCOME TAXES. The provision for income tax in 1999 and 1998
represented minimum state taxes.

         COMPARISON OF 1998 AND 1997 RESULTS

         NET REVENUES. Net revenues in 1998 were $24.7 million, an increase
from net revenues of $23.3 million in 1997. Net revenues by product group for
the years ended December 31, 1998 and 1997 were as follows ($ in thousands):

</TABLE>

         The increase in frame relay access and circuit management and
service revenues, was due to several large orders placed and fulfilled during
1998. The reduction in transmission products reflects a reduction in sales of
transmission products to the Pacific Rim caused by the continued currency and
financial instability in the region.

         The percentage of net revenues represented by sales through channel
partners and other resellers declined to 62.5% in 1998 from 67.0% in 1997.
Sales to IBM accounted for 14.1% and 16.5% of the Company's net revenues in
1998 and 1997, respectively.

         International sales accounted for 6.9% of net revenues in 1998, as
compared to 19.1% of net revenues in 1997 primarily due to a decrease in
sales to the Pacific Rim due to economic conditions in that region.

         GROSS PROFIT. Gross profit increased slightly to $8.9 million for
1998 compared to $8.5 million in 1997. Gross profit as a percentage of net
revenues decreased to 35.8% for the year ended December 31, 1998 from 36.7%
for the year ended December 31, 1997, due primarily to increased discounts to
IBM in 1998, as well as a decrease in average selling prices.

         OPERATING EXPENSES. Research and development expenses increased
slightly to $7.4 million for the

                                        21
<PAGE>

year ended December 31, 1998, from $7.2 million for the year ended December
31, 1997.

         Selling and marketing expenses decreased to $11.9 million for the
year ended December 31, 1998 from $14.3 million for the year ended December
31, 1997. The decreased expenses resulted primarily from sales and marketing
consultant and employee headcount reductions.

         General and administrative expenses decreased to $3.0 million for
the year ended December 31, 1998, as compared to $3.7 million for the year
ended December 31, 1997. The decrease in general and administrative expenses
was primarily due to the Company's expense reduction programs.

         In the first and fourth quarters of fiscal 1997, the Company
implemented various expense reduction programs to improve its results of
operations. In connection with these programs, the Company recorded a
non-recurring charge of $1.2 million, consisting of severance and related
headcount reduction costs and lease termination costs related to redundant
sales office facilities.

       The non-recurring charges taken in 1998 and 1997 were as follows (in
thousands):

</TABLE>

         In 1998, the Company completed its 1997 expense reduction program
activities.

         Net interest income in 1998 decreased to $0.9 million from $1.5 million
in 1997 primarily due to lower cash balances.

         INCOME TAXES. The provision for income tax in 1998 represented minimum
state taxes. There were no provisions for income taxes in 1997.

INFLATION

         The effects of inflation have not historically had, and are not
expected to have, a material effect on the Company's operating results or
financial condition.

YEAR 2000 COMPLIANCE

         Many currently installed computer and telecommunications systems and
software products were not designed to consider the impact of moving into the
21st century. To date, the Company has tested its products and internal systems
for Year 2000 compliance and has verified that its significant vendors,
customers and service provides or any other third party upon which it
significantly relies have taken prudent measures to mitigate the risk of the
Year 2000. The Company has not experienced or been informed of any significant
Year 2000 issues that may directly or indirectly affect its business. The
Company will continue to monitor and evaluate the impact of the Year 2000 upon
its overall business as latent Year 2000 related issues may arise in the future.

         To date, the Company has not incurred substantial costs to address the
Year 2000 issue and is unable to estimate the additional cost, if any, that may
arise from Year 2000 related issues identified in the future.

         Despite the Company's efforts to address the Year 2000 impact on its
products, internal systems and business operations, latent Year 2000 related
issues may result in a material disruption of its business or have a material
adverse effect on the Company's business, financial condition or results of
operations.

LIQUIDITY AND CAPITAL RESOURCES

         As of December 31, 1999, the Company's principal sources of liquidity
consisted of $8.6 million of cash and cash equivalents. The Company also has
available a $2 million secured bank line of credit which will expire in April
2000. There were no borrowings outstanding as of December 31, 1999.

         During 1999, cash used in operating activities was $4.8 million,
compared to $6.5 million for fiscal 1998. Use of cash during 1999 resulted
primarily from the Company's net loss of $4.3 and the payment of costs
associated with the Company's restructuring plan. Capital expenditures during
fiscal 1999 were $0.6 million, compared to $1.2 million for 1998. At December
31, 1999, the Company had no material commitments for capital expenditures.

         As of December 31, 1999, the Company's net working capital was $11.6
million, of which $8.6 million was invested in cash and cash equivalents, $3.2
million was invested in accounts receivable, and $5.1 million was invested in
inventory. The Company believes that its available cash and cash equivalents
will be sufficient to meet its working capital requirements at least through
2000.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

RISKS ASSOCIATED WITH FOREIGN EXCHANGE

         In 1999, approximately 13.2% of the Company's net revenues were derived
from sales to international customers, primarily in the Pacific Rim and Europe.
As a result, the Company is exposed to market risk from changes in foreign
exchange rates and international economic conditions, which could affect its
results of operations and financial condition. In order to reduce the risk from
fluctuation in foreign exchange rates, the Company's product sales are
denominated in U.S. dollars. The Company has not entered into any currency
hedging activities.

INTEREST RATE RISKS

         The Company invests its excess cash in high quality government and
corporate debt instruments. However, the Company may be exposed to fluctuation
in rates on these investments. Increases or decreases in interest rates
generally translate into increases or decreases in the fair value of these
investments. Such changes to these investments have historically not been
material due to the short-term nature of the Company's investment. In addition,
the credit worthiness of the issuer, the relative values of alternative
investments, the liquidity of the instruments and other general market
conditions may affect the fair value of interest rate sensitive instruments. In
order to reduce the risk from fluctuation in rates, the Company invests in money
market funds and short-term debt instruments of U.S. corporations with strong
credit ratings and the federal government with contractual maturities of less
than six months. At December 31, 1999, investments were as follows
($ in millions):

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         COMPANY BACKGROUND

         Sync Research, Inc. (the "Company") develops, manufactures, markets,
supports and provides wide-area network ("WAN") access and management products
and services designed to economically and reliably support business critical
applications across carrier provided packetized transmission services, such as
frame relay.

         BASIS OF PRESENTATION

         The accompanying consolidated financial statements include the accounts
of Sync Research, Inc. and its subsidiaries (the Company). All significant
intercompany transactions and balances have been eliminated in consolidation.

         RECLASSIFICATIONS AND STOCK SPLIT

         Certain prior year amounts have been reclassified to conform with the
current year presentation. The company effected a one for five reverse stock
split in June 1999. All share and per share information in the accompanying
financial statements have been restated to reflect this reverse stock split.

         USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
Significant estimates made in preparing the consolidated financial statements
include the allowance for doubtful accounts, certain accrued liabilities,
inventory reserves, and income tax valuation allowances.

         CASH AND CASH EQUIVALENTS

         The Company invests its excess cash in money market funds and
short-term debt instruments of U.S. corporations with strong credit ratings. The
Company has established guidelines with respect to the diversifications and
maturities that maintain safety and liquidity. The Company considers all highly
liquid investments with an original maturity of 90 days or less and money market
funds to be cash equivalents.

         INVENTORIES

         Inventories are stated at the lower of cost or market. Cost is
determined on the first-in, first-out method. Inventories consisting primarily
of computer hardware and components are as follows (in thousands):

         REVENUE RECOGNITION

         The Company derives its revenues primarily from sales of wide-area
networking hardware and software products, which are recognized upon shipment.
The Company generally does not have any significant remaining obligations upon
shipment of its products. Product returns and sales allowances are provided for
at the date of sale. Service revenues from customer maintenance fees for ongoing
customer support and product updates and installation or other assistance are
recognized ratably over the term of the maintenance period, which is typically
12 months or as the work is performed.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         CAPITALIZED SOFTWARE

         Software development costs incurred subsequent to determination of
technical feasibility are capitalized. Based on the Company's product
development process, technological feasibility is established upon completion of
a working model. Costs incurred between completion of the working model and the
point at which the product is ready for initial shipment have historically not
been significant. Amortization begins when products is available for general
release to customers. The Company also capitalizes costs related to the purchase
or license of software developed by third parties which are used in certain of
its products. Such costs are amortized over the applicable license period or
estimated useful life of the product. In connection with its cost reduction
program, the Company wrote off $405,000 of its capitalized purchased software in
1999 as such software products were no longer supported.

         FURNITURE, FIXTURES AND EQUIPMENT

         Furniture, fixtures and equipment are recorded at cost. Depreciation
and amortization are provided on the straight-line method over the following
estimated useful lives:

<TABLE>

       Computers, software and equipment                     3 to 7 years
       Leasehold improvements                                Term of lease
</TABLE>

         LONG-LIVED ASSETS

         Long-lived assets and certain identifiable intangibles held and used by
the Company are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. If required, the recoverability test is performed at the lowest
level practicable based on undiscounted net cash flows.

         RESEARCH AND DEVELOPMENT

         Research and development costs are expensed as incurred. Continuous
research and development is necessary for the Company to maintain its
competitive position.

         WARRANTY

         The Company provides a warranty on all products and records a related
provision for estimated warranty costs at the date of sale.

         INCOME TAXES

         Deferred income tax assets and liabilities are computed for the
difference between the financial statement and tax basis of assets and
liabilities based on enacted tax laws and rates applicable to the period in
which differences are expected to affect taxable income. Valuation allowances
are established, when necessary to reduce deferred tax assets to amounts which
are more likely than not to be realized. The provision for income taxes consists
of the taxes payable and refundable for the period plus or minus the change
during the period in deferred income tax assets and liabilities.

         NON-RECURRING CHARGES

         In the first and fourth quarters of fiscal 1997, the Company
implemented various expense reduction programs to improve its results of
operations. In connection with these programs, the Company recorded a
non-recurring charge of $1.2 million, consisting of severance and related
headcount reduction costs and lease termination costs related to redundant sales
office facilities.

         During the fourth quarter of fiscal 1998, the Company implemented
additional expense reduction programs to reduce its overall cost structure and,
as a result, recognized a $2.9 million non-recurring charge consisting of
severance and related headcount reduction costs, idle and excess facility
charges

         STOCK-BASED COMPENSATION

         The Company has elected to use the intrinsic value method described
in Accounting Principles Board Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO
EMPLOYEES(APB 25) and related Interpretations in accounting for its employee
stock options.

          EARNINGS (LOSS) PER SHARE

3. CONCENTRATION OF BUSINESS AND CREDIT RISK

         The Company operates in a market which is subject to rapid
technological advancement and competition. The introduction of
technologically advanced products by competitorsand new technological
developments could have a substantial impact on the future operations of the
Company.

         A substantial portion of the Company's revenues are concentrated
with a few communications, networking, and telecommunications companies and
large enterprise end-user organizations. Sales to six customers represented
49.9% of the Company's total revenues in 1999. There was no single customer
in 1999 that represented more than 10% of the Company's total revenues.
Revenue from two customers represented 18.5% and 14.1% of the Company's total
revenues in 1998. Sales to one customer represented 16.5% of total revenues
in 1997.

         Accounts receivable represent the Company's only significant financial
instrument with potential

credit risk. The Company performs periodic credit evaluations of its
customer's financial condition and generally does not require collateral.
Credit losses have been within management's expectations and within amounts
provided through the allowances for doubtful accounts. To date, the Company
has not experienced any material write-offs or collection problems. At
December 31, 1999, five major customers represented 56.1% of total accounts
receivable.

         The Company is dependent upon certain suppliers of key components
and contract manufacturers.

         Revenues from foreign customers, primarily in Europe and the Pacific
Rim, aggregated $2.4 million or 13.2% and $1.7 million or 6.9%, and $4.5
million or 19.1%, of revenues in 1999, 1998 and 1997, respectively.

         The Company has approximately $59 million of federal net operating
loss carryforwards, including acquired net operating losses of an acquired
entity, Tylink Corporation, which will begin to expire in 2006. Approximately
$11 million of this loss carryforward is attributable to deductions from the
exercise of non-statutory stock options. A valuation allowance has been
established for the entire deferred tax asset related to these net operating
losses. When realized, the federal and state tax benefits related to the
reversal of this valuation allowance will be applied to reduce income tax
expense, except for the portion of the net operating losses that relates to
the deductions for the exercise of non-qualified stock options which will be
directly credited to additional paid-in capital.

         Deferred income taxes reflect the net tax effects of temporary
differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes.
Significant components of the Company's deferred taxes are as follows (in
thousands):

</TABLE>

         The Tax Reform Act of 1986 contains provisions which could
substantially limit the availability of the net operating loss carryforwards
if there is a greater than 50% change in ownership during a three year
period. As a result of the initial public offering and the Merger with Tylink
Corporation, the Company and TyLink experienced an ownership change of more
than 50%, resulting in a limitation on the utilization of their net operating
loss carryforwards. The limitation is based on the value of the companies on
the date that the effective change in ownership occurred. Management cannot
determine whether the limitation on the net operating losses will have a
material adverse effect on the Company's ability to fully utilize its net
operating loss carryforwards in the future. The ultimate realization of the
loss carryforwards is dependent on the future profitability of the Company.

5. EMPLOYEE BENEFIT PLANS

         The Company sponsors a plan (the Plan) pursuant to Section 401(k) of
the Internal Revenue Code (the Code), whereby substantially all eligible
employees may contribute a percentage of their compensation, subject to a
maximum allowed under the Code. The Company may contribute to the Plan, as
determined by the Board of Directors. For the years ended December 31, 1999,
1998 and 1997, matching contributions made and expensed by the Company
aggregated $104,000, $149,000 and $164,000, respectively.

         The Company sponsors an Employee Stock Purchase Plan (the Purchase
Plan), under which 40,000 shares of Common Stock has been reserved for
issuance. Under the Purchase Plan, the Company's employees meeting certain
eligibility requirements, may elect on a semiannual basis to purchase Common
Stock through payroll deductions, which may not exceed 5% of each employee's
compensation (subject to certain limitations). The stock price is set at the
lower of 85% of the fair market value of the Company's common stock at the
beginning or end of each semiannual offering period.

6. STOCK OPTIONS

         The Company has various stock option plans that provide for the
granting of incentive or non-statutory stock options to certain key
employees, non-employee members of the Board of Directors, consultants and
independent contractors. Options are granted at a price equal to 100% of the
fair market value of the Company's common stock at the date of grant. Options
typically vest at a rate of 25% of the shares on the first anniversary of the
vesting commencement date and 1/48th of the shares at the end of

                                        34

each month and expire not later than 10 years from the date of grant. The
number of shares reserved and available for grant under these plans
aggregated 1,672,816 and 199,539 shares, respectively, at December 31, 1999.

         The Company has elected to follow the intrinsic value method
described in APB Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES and
related Interpretations in accounting for its plans. Accordingly, no
compensation expense has been recognized for its stock option awards and its
stock purchase plan because the exercise price of the Company's stock options
equals the market price of the underlying stock on the date of grant.

         A summary of the Company's stock option activity, and related
information for the years ended December 31 follows:

COMPENSATION OF DIRECTORS

         Mr. Reyes, the Chairman of the Board of Directors, earned $68,000
($6,000 per month through October 1999 and $4000 per month thereafter) during
1999 pursuant to a consulting agreement with the Company. Non-employee
directors are paid a fee of $5,000 per quarter plus $1,000 for each full
meeting of the Board of Directors attended by such director. Directors are
reimbursed for out-of-pocket travel expenses associated with their attendance
at Board meetings. Non-employee directors of the Company will automatically
be granted options to purchase shares of the Company's Common Stock pursuant
to the terms of the Company's 1995 Directors' Stock Option Plan (the
"Directors' Plan"). Under the Directors' Plan, each non-employee director who
is elected to the Board will receive an option to purchase 8,000 shares of
Common Stock on the date on which he or she first becomes a non-employee
director. In addition, on the date of each annual stockholders meeting, each
non-employee director, will be granted an additional option to purchase 2,000
shares of Common Stock if, on such date, he or she has served on the Board
for at least six months and remains a director as of the date of such
meeting. Each option becomes exercisable at the rate of 25% of the total
number of shares subject to such option on the first anniversary of the grant
date, and 1/48th of the total number shares at the end of each month
thereafter.Options granted under the Directors' Plan have an exercise price
equal to the fair market value of the Company's Common Stock on the date of
grant and a term of ten years. Messrs. Haggerty and Schroeder each received
options to purchase 2,000 shares pursuant to the Directors' Plan in 1999.
Subject to their election to the Board of Directors by the stockholders at
the Company's annual meeting of stockholders in 2000, Messrs. Haggerty and
Schroeder will be automatically granted an option to purchase 2,000 shares of
Common Stock each on the date of the annual meeting. There are no family
relationships among the directors or executive officers of the Company.

EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS

         The Company enters into Change of Control Severance Agreements with
each of its officers. These agreements provide that upon a change of control
of the Company, fifty percent (50%) of the officer's unvested options shall
immediately vest. The remaining unvested options shall continue to vest at
the same rate as the officer's original vesting schedule, so that the same
number of options continue to vest per month as did prior to the change in
control. In addition, the agreements provide that the Company will enter into
consulting arrangements with each such officer if he or she is involuntary
terminated without cause or has his or her duties significantly reduced or is
otherwise constructively terminated within twelve (12) months after a change
of control of the Company. These consulting arrangements will last for up to
twelve months after such officer's termination. The agreements provide that,
during the consultation period, the officer will continue to receive
compensation at the rate at which he or she was previously compensated during
the twelve months prior to such termination. In addition, the terminated
officer's unvested options will continue to vest during the consultancy
period.

         On November 6, 1998, the Company entered into a Management Agreement
with Richard W. Martin. Pursuant to this agreement, upon a merger, sale or
other change of control of the Company, while Mr. Martin serves as Chief
Executive Officer of the Company. The Company has agreed to pay Mr. Martin an
amount equal to $500,000 less the aggregate gross profit received by Mr.
Martin from the sale of securities of the Company held by him in such
transaction. On April 9, 1999, the Company and Mr. Martin amended the
agreement to reduce the payment upon a merger, sale or change of control to
the greater of $250,000 or cash equal to 2% of the value of stock or cash
received by stockholders of the Company in such transaction provided that
such payment shall not exceed $500,000. In addition, the amended Management
Agreement provides that if Mr. Martin is terminated in connection with a
sale, merger or other change of control transaction, he will continue to
receive his base salary and benefits for a period not to exceed three months
following the closing of such transaction. Mr. Martin resigned as Chief
Executive Officer and an employee of the Company effective as of October 1999
and thus the Company has no further obligations under the Management
Agreement.

         The 1991 Plan provides that in the event of a merger or sale of all
or substantially all of the assets of the Company, the Administrator of the
1991 Plan will either accelerate the vesting of options and stock purchase
rights held by all employees, including executive officers, or shall
accomplish the assumption or substitution of such options and stock purchase
rights by the successor corporation.

         On October 8, 1999, the Company entered into an Amended and Restated
Change-of-Control Severance Agreement with William K. Guerry. Pursuant to
this agreement 1) Upon a merger, sale or other change of control of the
Company, while Mr. Guerry serves as Chief Executive Officer of the Company,
50% of Mr. Guerry's options to purchase Common Stock of the Company shall
immediately fully vest and 2) If Mr. Guerry's employment terminates as a
result of involuntary termination other than for cause at any time within
twelve months following a change of control, then, Mr. Guerry shall continue
as a consultant for up to twenty four months at Mr. Guerry's compensation
prior to termination including insurance coverage and 3) Vesting of Mr.
Guerry's stock options shall continue to vest during the consulting period.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         During 1999, Messrs. Haggerty and Schroeder comprised the
Compensation Committee of the Board of Directors. None of these persons has
ever been an officer or employee of the Company or any of its subsidiaries.
There were no compensation committee interlocks or other relationships during
1998 requiring disclosure under Item 402(j) of Regulation S-K of the
Securities and Exchange Commission.

REPORT OF COMPENSATION COMMITTEE

         During 1999, the Compensation Committee of the Board consisted of
Charles A. Haggerty and William Schroeder, both of whom are non-employee
directors. The Compensation Committee, in conjunction with the Board of
Directors, establishes salaries, incentives and other forms of compensation
for directors, officers and other employees, administers the various
incentive compensation and benefit plans (including the Company's stock
purchase and stock option plans) and recommends policies relating to such
plans. The Compensation Committee also has the exclusive responsibility for
granting options and stock purchase rights under the 1991 Stock Plan to
executive officers and eligible directors. The Compensation Committee will
annually evaluate the performance and determine compensation and long-term
equity incentives of the Chief Executive Officer (the "CEO"), and will review
and approve the CEO's compensation recommendation for other executive
officers of the Company.

         The Company's executive compensation program consists of three main
components: (1) base salary, (2) potential for a quarterly and/or annual
bonuses based on overall Company performance as well as individual
performance and (3) stock and/or option grants which provide the executive
officers with the opportunity to build a meaningful stake in the Company, and
which stock and/or options are granted with the objective of aligning
executive officers' long-range interests with those of the stockholders and
encouraging the achievement of superior results over time. The second and
third elements of the compensation program constitute the "at risk"
components.

         The Company believes that, in order to attract and retain talented
individuals, it is important to set the base salaries of its executives at
levels that are competitive with those of companies in similar industries, of
comparable size and in the Company's same geographic area. Compensation
committee members utilize their experience, and publicly available resources
as appropriate to determine these base figures.

ANNUAL OR QUARTERLY CASH BONUSES

         The Company historically has not had a formal cash bonus program for
executive officers, although cash bonuses have been paid from time to time in
the past to selected executive officers in recognition of superior individual
performance. The Company has paid Mr. Favazza incentive compensation in 1997,
1998, 1999 and he may earn incentive compensation in 2000 equal to a certain
percentage of his respective salary based upon the Company's revenue levels.
None of the executive officers of the Company earned bonuses during fiscal
1999.

         Because stock options and stock grants provide an incentive for
executives to maximize stockholder value over time, stock options and stock
grants are a key means of aligning the interests of management and
stockholders. Value accrues to executives only as the value of the Company's
stock appreciates. The Company's typical vesting schedule for all employee
options (including options granted to executive officers) is as follows: 25%
of the total number of shares subject to the option vest one year after the
date of grant and 1/48th of the total number of shares subject to the option
vest at the end of each month thereafter. These vesting schedules are
intended to encourage a long-term commitment to the Company by its executive
officers. The number of shares owned by, or subject to options held by, each
executive officer is periodically reviewed and additional awards are
considered based upon past performance of the executive and the relative
holdings of other executives in the Company and at other companies in the
telecommunications industry. In 1999, the Company granted stock options under
the 1996 Non-Executive Stock Option Plan (the 1996 Stock Plan) to one new
executive officer, Mr. Rambert (75,000 shares), in connection with his
appointment as an executive officer and stock options under the 1991 Stock
Plan to four executive officers,


                                        45
<PAGE>

Messrs. Guerry (105,000 shares), Favazza (105,000 shares), Thunen (105,000
shares) Martin (20,000 shares) and McNally (5,000 shares).

         The Compensation Committee will meet during the year and will
consult as needed with the Company's CEO to establish the compensation
program for the next year and to evaluate the effectiveness of the Company's
compensation program in meeting its objectives. Additionally, the
Compensation Committee may hold special meetings to approve the compensation
of a newly hired executive or an executive whose scope of responsibility has
significantly changed. Compensation for executive officers will be based on
compensation surveys and assessments as to the demonstrated and sustained
performance of the individual executives.

 CHIEF EXECUTIVE OFFICER COMPENSATION

         The Compensation Committee evaluates the performance of the
Company's Chief Executive Officer, sets his base compensation and determines
bonuses and awards stock or option grants, if any. The Compensation Committee
determines the CEO's base salary after evaluating a number of factors,
including comparative salaries of chief executive officers of companies of
comparable size in the telecommunications industry, the Chief Executive
Officer's individual performance and the Company's performance.

         William K. Guerry was named President and Chief Executive Officer
effective October 1999. From June 1997, Mr. Guerry has also served as the
Company's Chief Financial Officer. In connection with his appointment as Chief
Executive, the board granted Mr. Guerry a non-statutory stock option under
the 1991 stock plan for 95,000 shares and increase his salary from $150,000
to $200,000.

         Richard W. Martin served as the Chief Executive Officer of the
Company from June 1998 to October 1999.In connection with his appointment,
the board granted Mr. Martin a non-statutory stock option under the 1991
stock plan for 65,000 shares. In connection with repricing of options in
October 1998, the Board determined not to reprice Mr. Martin's
options. Alternatively, the Board granted Mr. Martin an option to purchase
20,000 shares at $5.625 per share.

COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M)

         Section 162(m) of the Internal Revenue Code, enacted in 1993,
generally disallows a tax deduction to publicly held companies for
compensation exceeding $1 million paid to certain of the corporation's
executive officers. However, compensation which qualifies as
"performance-based" is excluded from the $1 million limit if, among other
requirements, the compensation is payable upon attainment of pre-established,
objective performance goals under a plan approved by the stockholders.

         The compensation to be paid to the Company's executive officers for
the 1999 fiscal year did not exceed the $1 million limit per officer, nor is
it expected that the compensation to be paid to the company's executive
officers for fiscal 1999 will exceed that limit. The Company's 1991 Stock
Plan is structured so that any compensation income realized by an executive
officer as a result of the exercise of an outstanding option or the sale of
option shares under the 1991 Stock Plan or the 1996 Stock Plan will qualify
as "performance-based" compensation which will not be subject to the $1
million limitation. Because it is very unlikely that the cash compensation
payable to any of the Company's executive officers in the foreseeable future
will approach the $1 million limit, the Compensation Committee has decided at
this time not to take any other action to limit or restructure the elements
of cash compensation payable to the Company's executive officers. The
Compensation Committee will continue to monitor the compensation levels
potentially payable under the Company's cash compensation programs, but
intends to retain the flexibility necessary to provide total cash
compensation in line with competitive practice, the Company's compensation
philosophy and the Company's best interests.

         2.2      ANNUAL MEETING

         (a) The annual meeting of stockholders shall be held each year on a

the corporation's notice with respect to such meeting, (ii) by or at the

<PAGE>

was a stockholder of record at the time of giving of the notice provided for

must have given timely notice thereof in writing to the secretary of the

delivered not earlier than the ninetieth (90th) day prior to such annual meeting
and not later than the close of business on the later of the twentieth (20th)
day prior to such annual meeting or the tenth (10th) day following the day on

stockholder's notice shall set forth (i) as to each person whom the stockholder
proposes to nominate for election or reelection as a director all information
relating to such person that is required to be disclosed in solicitations of
proxies for election of directors, or is otherwise required, in each case
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(the "Exchange Act") (including such person's written consent to being named in
the proxy statement as a nominee and to serving as a director if elected); (ii)
as to any other business that the stockholder proposes to bring before the
meeting, a brief description of such business, the reasons for conducting such
business at the meeting and any material interest in such business of such
stockholder and the beneficial owner, if any, on whose behalf the proposal is
made; and (iii) as to the stockholder giving the notice and the beneficial
owner, if any, on whose behalf the nomination or proposal is made (A) the name
and address of such stockholder, as they appear on the corporation's books, and
of such beneficial owner and (B) the class and number of shares of the
corporation which are owned beneficially and of record by such stockholder and
such beneficial owner.

         (d) Only such business shall be conducted at an annual meeting of
stockholders as shall have been brought before the meeting in accordance with
the procedures set forth in this Section 2.2. The chairman of the meeting shall
determine whether a nomination or any business proposed to be transacted by the
stockholders has been properly brought before the meeting and, if any proposed
nomination or business has not been properly brought before the meeting, the
chairman shall declare that such proposed business or nomination shall not be
presented for stockholder action at the meeting.

         (e) For purposes of this Section 2.2, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or a comparable national news service.

<PAGE>

         (f) Nothing in this Section 2.2 shall be deemed to affect any rights of
stockholders to request inclusion of proposals in the corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act.

         2.3      SPECIAL MEETING

         (a) A special meeting of the stockholders may be called at any time by
the Board of Directors, or by the chairman of the board, or by the president.

         (b) Nominations of persons for election to the Board of Directors may
be made at a special meeting of stockholders at which directors are to be
selected pursuant to such notice of meeting (i) by or at the direction of the
Board of Directors or (ii) by any stockholder of the corporation who is a
stockholder of record at the time of giving of notice provided for in Section
2.5, who shall be entitled to vote at the meeting and who complies with the
notice procedures set forth in Section 2.5.

         2.4      NOTICE OF STOCKHOLDERS' MEETINGS

         All notices of meetings of stockholders shall be in writing and shall
be sent or otherwise given in accordance with Section 2.5 of these Bylaws not
less than ten (10) nor more than sixty (60) days before the date of the meeting
to each stockholder entitled to vote at such meeting. The notice shall specify
the place, date and hour of the meeting, and, in the case of a special meeting,
the purpose or purposes for which the meeting is called.

         2.5      ADVANCE NOTICE OF STOCKHOLDER NOMINEES

         Only persons who are nominated in accordance with the procedures set
forth in this Section 2.5 shall be eligible for election as directors.
Nominations of persons for election to the Board of Directors of the corporation
may be made at a meeting of stockholders by or at the direction of the Board of
Directors or by any stockholder of the corporation entitled to vote for the
election of directors at the meeting who complies with the notice procedures set
forth in this Section 2.5. Such nominations, other than those made by or at the
direction of the Board of Directors, shall be made pursuant to timely notice in
writing to the secretary of the corporation. To be timely, a stockholder's
notice shall be delivered to or mailed and received at the principal executive
offices of the corporation not less than sixty (60) days nor more than ninety
(90) days prior to the meeting; provided, however, that in the event that less
than sixty (60) days' notice or prior public disclosure of the date of the
meeting is given or made to stockholders, notice by the stockholder to be timely
must be so received not later than the close of business on the 10th day
following the day on which such notice of the date of the meeting was mailed or
such public disclosure was made. Such stockholder's notice shall set forth (a)
as to each person whom the stockholder proposes to nominate for election or
re-election as a Director, (i) the name, age, business address and residence
address of such person, (ii) the principal occupation or employment of such
person, (iii) the class and number of shares of the corporation which are
beneficially owned by such person and (iv) any other information relating to
such person that is required to be disclosed in solicitations of proxies for
election of Directors, or is otherwise required, in each case pursuant to
Regulation 14A under the Securities Exchange Act of 1934, as

                                  -iv-
<PAGE>

amended (including, without limitation, such person's written consent to
being named in the proxy statement as a nominee and to serving as a director
if elected); and (b) as to the stockholder giving the notice (1) the name and
address, as they appear on the corporation's books, of such stockholder and
(2) the class and number of shares of the corporation which are beneficially
owned by such stockholder. At the request of the Board of Directors any
person nominated by the Board of Directors for election as a director shall
furnish to the secretary of the corporation that information required to be
set forth in a stockholder's notice of nomination which pertains to the
nominee. No person shall be eligible for election as a director of the
corporation unless nominated in accordance with the procedures set forth in
this Section 2.5. The Chairman of the meeting shall, if the facts warrant,
determine and declare to the meeting that a nomination was not made in
accordance with the procedures prescribed by the Bylaws, and if he or she
should so determine, he or she shall so declare to the meeting and the
defective nomination shall be disregarded.

         2.6      MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

         Written notice of any meeting of stockholders, if mailed, is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his or her address as it appears on the records of the
corporation. An affidavit of the secretary or an assistant secretary or of the
transfer agent of the corporation that the notice has been given shall, in the
absence of fraud, be prima facie evidence of the facts stated therein.

         2.7      QUORUM

         The holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the certificate of
incorporation. If, however, such quorum is not present or represented at any
meeting of the stockholders, then either (i) the chairman of the meeting or (ii)
the stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum is present or
represented. At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

         2.8      ADJOURNED MEETING; NOTICE

         When a meeting is adjourned to another time or place, unless these
Bylaws otherwise require, notice need not be given of the adjourned meeting if
the time and place thereof are announced at the meeting at which the adjournment
is taken. At the adjourned meeting the corporation may transact any business
that might have been transacted at the original meeting. If the adjournment is
for more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

         2.9      CONDUCT OF BUSINESS


                                   -v-
<PAGE>

         The chairman of any meeting of stockholders shall determine the order
of business and the procedure at the meeting, including such regulation of the
manner of voting and the conduct of business.

         2.10     VOTING

         The stockholders entitled to vote at any meeting of stockholders shall
be determined in accordance with the provisions of Section 2.12 of these Bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint owners
of stock and to voting trusts and other voting agreements).

         Except as provided in the last paragraph of this Section 2.10, or as
may be otherwise provided in the certificate of incorporation, each stockholder
shall be entitled to one vote for each share of capital stock held by such
stockholder.

         2.11     WAIVER OF NOTICE

         Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these Bylaws.

         2.12     RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS

         In order that the corporation may determine the stockholders entitled
to notice of or to vote at any meeting of stockholders or any adjournment
thereof, or entitled to receive any payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty (60) nor less than ten (10) days before the
date of such meeting, nor more than sixty (60) days prior to any other action.

         If the Board of Directors does not so fix a record date:

                  (a) The record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held.


                                 -vi-
<PAGE>

                  (b) The record date for determining stockholders for any other
purpose (other than determining stockholders entitled to consent to corporate
action in writing without a meeting) shall be at the close of business on the
day on which the Board of Directors adopts the resolution relating thereto.

         A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a record date for the
adjourned meeting.

         2.13     PROXIES

         Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for him by a written proxy, signed by
the stockholder and filed with the secretary of the corporation, but no such
proxy shall be voted or acted upon after three (3) years from its date, unless
the proxy provides for a longer period. A proxy shall be deemed signed if the
stockholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by the stockholder or the
stockholder's attorney-in-fact. The revocability of a proxy that states on its
face that it is irrevocable shall be governed by the provisions of Section
212(c) of the General Corporation Law of Delaware.

                                   ARTICLE III

                                    DIRECTORS

         3.1      POWERS

         Subject to the provisions of the General Corporation Law of Delaware
and any limitations in the certificate of incorporation or these Bylaws relating
to action required to be approved by the stockholders or by the outstanding
shares, the business and affairs of the corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the Board of
Directors.

         3.2      NUMBER OF DIRECTORS

         The Board of Directors shall consist of four (4) persons until changed
by a proper amendment of this Section 3.2.

         No reduction of the authorized number of directors shall have the
effect of removing any director before that director's term of office expires.

         3.3      ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTOR

         Except as provided in Section 3.4 of these Bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Directors need not

to be stockholders unless so required by the certificate of incorporation or
these Bylaws, wherein other qualifications for directors may be prescribed.
Each director, including a director elected to fill a vacancy, shall hold
office until his successor is elected and qualified or until his earlier
resignation or removal.

         Elections of directors need not be by written ballot.

         3.4      RESIGNATION AND VACANCIES

         Any director may resign at any time upon written notice to the

Preferred Stock, and except as otherwise determined by the Board of Directors or
required by law, newly created directorships resulting from any increase in the
authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the directors
then in office, though less than a quorum, or the sole remaining director;
directors so chosen shall hold office for a term expiring at the next annual
meeting of stockholders and until such director's successor shall have been duly
elected and qualified.

         If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these Bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

         If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole board (as constituted immediately prior to any such increase), then
the Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten percent (10%) of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office as aforesaid,
which election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

the Board of Directors, may participate in a meeting of the Board of Directors,
or any committee, by means of conference

<PAGE>

participating in the meeting can hear each other, and such participation in a
meeting shall constitute presence in person at the meeting.

         3.6      REGULAR MEETINGS

         Regular meetings of the Board of Directors may be held without notice
at such time and at such place as shall from time to time be determined by the

telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally or by
telephone or by telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting. Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director. The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation.

         3.8      QUORUM

         At all meetings of the Board of Directors, a majority of the authorized
number of directors shall constitute a quorum for the transaction of business
and the act of a majority of the directors present at any meeting at which there
is a quorum shall be the act of the Board of Directors, except as may be
otherwise specifically provided by statute or by the certificate of
incorporation. If a quorum is not present at any meeting of the Board of
Directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

         3.9      WAIVER OF NOTICE

General Corporation Law of Delaware or of the certificate of incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be


                                    -ix-
<PAGE>

deemed equivalent to notice. Attendance of a person at a meeting shall
constitute a waiver of notice of such meeting, except when the person attends
a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not
lawfully called or convened. Neither the business to be transacted at, nor
the purpose of, any regular or special meeting of the directors, or members
of a committee of directors, need be specified in any written waiver of
notice unless so required by the certificate of incorporation or these Bylaws.

         3.10     BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

         Unless otherwise restricted by the certificate of incorporation or
these Bylaws, any action required or permitted to be taken at any meeting of the

writing and the writing or writings are filed with the minutes of proceedings of
the board or committee.

         3.11     FEES AND COMPENSATION OF DIRECTORS

         Unless otherwise restricted by the certificate of incorporation or

serving the corporation in any other capacity and receiving compensation
therefor.

         The corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the corporation or of its
subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation. The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the Board of
Directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation. Nothing contained in this section shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

         3.13     REMOVAL OF DIRECTORS

         Unless otherwise restricted by statute, by the certificate of
incorporation or by these Bylaws, any director or the entire Board of Directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors; provided, however,
that, so long as stockholders of the corporation are entitled to cumulative
voting, if less than the entire board is to be removed, no director may be
removed without cause if the votes cast against his or her removal would be
sufficient to elect him or her if then cumulatively voted at an election of the
entire Board of Directors.

Corporation Law of Delaware, fix the designations and any of the preferences or
rights of such shares relating to dividends, redemption, dissolution, any
distribution of assets of the corporation or the conversion into, or the
exchange of such shares for, shares of any other class or classes or any other
series of the same or any other class or classes of stock of the corporation or

Corporation Law of Delaware.

authorization thereof by the Board of Directors shall be paid by the corporation
in advance of the final disposition of such action or proceeding upon receipt of
an undertaking by or on behalf of the indemnified party to repay such amount if
it shall ultimately be determined that the indemnified party is not entitled to
be indemnified as authorized in this Article VI.

         6.4      INDEMNITY NOT EXCLUSIVE

         The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may be

action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the Articles of
Incorporation.

person who is or was a director, officer, employee or agent of the corporation,

against such liability under the provisions of the General Corporation Law of
Delaware.

         6.6      CONFLICTS

         No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

                  (a) That it would be inconsistent with a provision of the
certificate of incorporation, these Bylaws, a resolution of the stockholders or
an agreement in effect at the time of the accrual of the alleged cause of the
action asserted in the proceeding in which the expenses


                                   -xvi-
<PAGE>

were incurred or other amounts were paid, which prohibits or otherwise limits
indemnification; or

                  (b) That it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.

right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom. A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder. In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder. The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

         7.2      INSPECTION BY DIRECTORS

         Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his position as a director. The Court of Chancery
is hereby vested with the exclusive jurisdiction to determine whether a director
is entitled to the inspection sought. The Court may summarily order the
corporation to permit the director to inspect any and all books and records, the
stock ledger, and the stock list and to make copies or extracts therefrom. The
Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the Board of Directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

         8.3      STOCK CERTIFICATES; PARTLY PAID SHARES

         The shares of a corporation shall be represented by certificates,
provided that the Board of Directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the Board of
Directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the corporation by the chairman or vice-chairman of
the Board of Directors, or the chief executive officer or the president or vice
president, and by the chief financial officer or an assistant treasurer, or the
secretary or an assistant secretary of such corporation representing the number
of shares registered in certificate form. Any or all of the signatures on the
certificate may be a facsimile. In case any officer, transfer agent or registrar
who has signed or whose facsimile signature has been placed upon a certificate
has ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the corporation with the same effect
as if he or she were such officer, transfer agent or registrar at the date of
issue.

         The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent
any such partly paid shares, upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

         8.4      SPECIAL DESIGNATION ON CERTIFICATES

         If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences, and the relative,


                                   -xviii-
<PAGE>

participating, optional or other special rights of each class of stock or
series thereof and the qualifications, limitations or restrictions of such
preferences and/or rights shall be set forth in full or summarized on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock; PROVIDED, HOWEVER, that, except as otherwise
provided in Section 202 of the General Corporation Law of Delaware, in lieu
of the foregoing requirements there may be set forth on the face or back of
the certificate that the corporation shall issue to represent such class or
series of stock a statement that the corporation will furnish without charge
to each stockholder who so requests the powers, the designations, the
preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

         8.5      LOST CERTIFICATES

         Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time. The corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate theretofore issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify it against any claim that may be made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance of such new certificate or uncertificated shares.

         8.6      CONSTRUCTION; DEFINITIONS

         Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Delaware General Corporation Law shall
govern the construction of these Bylaws. Without limiting the generality of this
provision, the singular number includes the plural, the plural number includes
the singular, and the term "person" includes both a corporation and a natural
person.

         8.7      DIVIDENDS

         The directors of the corporation, subject to any restrictions contained
in (i) the General Corporation Law of Delaware or (ii) the certificate of
incorporation, may declare and pay dividends upon the shares of its capital
stock. Dividends may be paid in cash, in property, or in shares of the
corporation's capital stock.

         The directors of the corporation may set apart out of any of the funds
of the corporation available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing dividends, repairing or maintaining any property of the
corporation, and meeting contingencies.

         8.8      FISCAL YEAR

         The fiscal year of the corporation shall be fixed by resolution of the
Board of Directors and may be changed by the Board of Directors.


                                 -xix-

         8.9      SEAL

         The corporation may adopt a corporate seal, which may be altered at
pleasure, and may use the same by causing it or a facsimile thereof, to be
impressed or affixed or in any other manner reproduced.

         8.10     TRANSFER OF STOCK

         Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignation or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate, and record the transaction in its books.

         8.11     STOCK TRANSFER AGREEMENTS

         The corporation shall have power to enter into and perform any
agreement with any number of stockholders of any one or more classes of stock of
the corporation to restrict the transfer of shares of stock of the corporation
of any one or more classes owned by such stockholders in any manner not
prohibited by the General Corporation Law of Delaware.

         8.12     REGISTERED STOCKHOLDERS

         The corporation shall be entitled to recognize the exclusive right of a
person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                   ARTICLE IX

                                   AMENDMENTS

         The Bylaws of the corporation may be adopted, amended or repealed by
the stockholders entitled to vote; provided, however, that the corporation may,
in its certificate of incorporation, confer the power to adopt, amend or repeal
Bylaws upon the directors. The fact that such power has been so conferred upon
the directors shall not divest the stockholders of the power, nor limit their
power to adopt, amend or repeal Bylaws.

                                    ARTICLE X

                                   DISSOLUTION


                                   -xx-
<PAGE>

         If it should be deemed advisable in the judgment of the Board of
Directors of the corporation that the corporation should be dissolved, the
board, after the adoption of a resolution to that effect by a majority of the
whole board at any meeting called for that purpose, shall cause notice to be
mailed to each stockholder entitled to vote thereon of the adoption of the
resolution and of a meeting of stockholders to take action upon the resolution.

         At the meeting a vote shall be taken for and against the proposed
dissolution. If a majority of the outstanding stock of the corporation entitled
to vote thereon votes for the proposed dissolution, then a certificate stating
that the dissolution has been authorized in accordance with the provisions of
Section 275 of the General Corporation Law of Delaware and setting forth the
names and residences of the directors and officers shall be executed,
acknowledged, and filed and shall become effective in accordance with Section
103 of the General Corporation Law of Delaware. Upon such certificate's becoming
effective in accordance with Section 103 of the General Corporation Law of
Delaware, the corporation shall be dissolved.

         Whenever all the stockholders entitled to vote on a dissolution consent
in writing, either in person or by duly authorized attorney, to a dissolution,
no meeting of directors or stockholders shall be necessary. The consent shall be
filed and shall become effective in accordance with Section 103 of the General
Corporation Law of Delaware. Upon such consent's becoming effective in
accordance with Section 103 of the General Corporation Law of Delaware, the
corporation shall be dissolved. If the consent is signed by an attorney, then
the original power of attorney or a photocopy thereof shall be attached to and
filed with the consent. The consent filed with the Secretary of State shall have
attached to it the affidavit of the secretary or some other officer of the
corporation stating that the consent has been signed by or on behalf of all the
stockholders entitled to vote on a dissolution; in addition, there shall be
attached to the consent a certification by the secretary or some other officer
of the corporation setting forth the names and residences of the directors and
officers of the corporation.

                                   ARTICLE XI

                                    CUSTODIAN

         11.1     APPOINTMENT OF A CUSTODIAN IN CERTAIN CASES

         The Court of Chancery, upon application of any stockholder, may appoint
one or more persons to be custodians and, if the corporation is insolvent, to be
receivers, of and for the corporation when:

                  (i) at any meeting held for the election of directors the
stockholders are so divided that they have failed to elect successors to
directors whose terms have expired or would have expired upon qualification of
their successors; or

                  (ii) the business of the corporation is suffering or is
threatened with irreparable injury because the directors are so divided
respecting the management of the affairs of


                                   -xxi-
<PAGE>

the corporation that the required vote for action by the Board of Directors
cannot be obtained and the stockholders are unable to terminate this
division; or

                  (iii) the corporation has abandoned its business and has
failed within a reasonable time to take steps to dissolve, liquidate or
distribute its assets.

         11.2     DUTIES OF CUSTODIAN

         The custodian shall have all the powers and title of a receiver
appointed under Section 291 of the General Corporation Law of Delaware, but the
authority of the custodian shall be to continue the business of the corporation
and not to liquidate its affairs and distribute its assets, except when the
Court of Chancery otherwise orders and except in cases arising under Sections
226(a)(3) or 352(a)(2) of the General Corporation Law of Delaware.

SILICON VALLEY BANK


                         AMENDMENT TO LOAN AND SECURITY
                                    AGREEMENT

BORROWER:         SYNC RESEARCH, INC.
ADDRESS:          40 PARKER
                  IRVINE, CALIFORNIA  92618

DATED:            OCTOBER 31, 1999

         THIS AMENDMENT TO LOAN AGREEMENT is entered into between SILICON VALLEY
BANK ("Silicon") and the borrower named above (the "Borrower").

         The Parties agree to amend, effective as of the date hereof, the Loan
and Security Agreement between them, dated September 18, 1991, as amended by
that Extension Agreement dated August 3, 1992, by that Amendment to Loan
Agreement dated October 20, 1992, by that Amendment to Loan Agreement dated
August 23, 1993, by that Amendment to Loan Agreement dated February 10, 1994, by
that Amendment to Loan Agreement dated July 18, 1994, by that Amendment to Loan
Agreement dated September 20, 1994, by that Amendment to Loan and Security
Agreement dated August 31, 1995, by that Amendment to Loan and Security
Agreement (the "October 1995 Amendment") dated October 5, 1995, by that
Amendment to Loan Agreement dated July 3, 1996, by that Amendment to Loan and
Security Agreement dated October 6, 1996, by that Amendment to Loan and Security
Agreement dated June 10, 1997, by that Amendment to Loan and Security Agreement
dated as of December 3, 1997, and by that Amendment to Loan and Security
Agreement dated April 14, 1999 (as so amended and as otherwise amended from time
to time being referred to herein as the "Loan Agreement"), as follows.
(Capitalized terms used but not defined in this Agreement, shall have the
meanings set forth in the Loan Agreement.)

         1. REVISED CREDIT LIMIT. That section of the Schedule to Loan Agreement
entitled "Credit Limit (Section 1.1)" is hereby amended in its entirety to read
as follows:

     "CREDIT LIMIT
     (Section 1.1):                     An amount not to exceed (i) $2,000,000
                                        at any one time outstanding or (ii) 80%
                                        of the Net Amount of Borrower's
                                        accounts, which Silicon in its
                                        discretion deems eligible for borrowing.

                                        "Net Amount" of an account means the
                                        gross amount of the account, minus all
                                        applicable sales, use, excise and other
                                        similar taxes and minus all discounts,
                                        credits and allowances of any nature
                                        granted or claimed.

                                        Without limiting the fact that the
                                        determination of which accounts are
                                        eligible for borrowing is a matter of
                                        Silicon's discretion, the following will
                                        not be deemed eligible for

                                        to the extent they exceed 25% of the
                                        total eligible accounts outstanding,
                                        accounts owing from an affiliate of
                                        Borrower, and accounts owing from an
                                        account debtor to whom Borrower is or
                                        may be liable for goods purchased from
                                        such account debtor or otherwise. In
                                        addition, if more than 50% of the
                                        accounts owing from an account debtor
                                        are outstanding more than 90 days from
                                        the invoice date or are otherwise not
                                        eligible accounts, then all accounts
                                        owing from that account debtor will be
                                        deemed ineligible for borrowing.

                                        the Borrower as set forth above, Silicon

                                        credit obligations are not considered a
                                        sublimit of the Credit Limit set forth
                                        above."

                                  EXHIBIT 10.43

                               SYNC RESEARCH, INC.
                              AMENDED AND RESTATED
                      CHANGE OF CONTROL SEVERANCE AGREEMENT


         This Amended and Restated Change of Control Severance Agreement (the
"AGREEMENT") is made and entered into by and between William K. Guerry (the
"EMPLOYEE") and Sync Research, Inc., a Delaware corporation (the "COMPANY"),
effective as of October 8, 1999.

                                    RECITALS


         A. It is expected that the Company from time to time will consider
the possibility of an acquisition by another company or other change of
control. The Board of Directors of the Company (the "BOARD") recognizes that
such consideration can be a distraction to the Employee and can cause the
Employee to consider alternative employment opportunities. The Board has
determined that it is in the best interests of the Company and its
stockholders to assure that the Company will have the continued dedication
and objectivity of the Employee, notwithstanding the possibility, threat or
occurrence of a Change of Control (as defined below) of the Company.

         B. The Board believes that it is in the best interests of the Company
and its stockholders to provide the Employee with an incentive to continue his
or her employment and to motivate the Employee to maximize the value of the
Company upon a Change of Control for the benefit of its stockholders.

         C. The Board believes that it is imperative to provide the Employee
with certain severance benefits upon Employee's termination of employment
following a Change of Control that provide the Employee with enhanced financial
security and incentive and encouragement to the Employee to remain with the
Company notwithstanding the possibility of a Change of Control.

         D. For the reasons set forth in these recitals, the Company and
Employee entered into a Change of Control Severance Agreement dated June 23,
1997 (the "PRIOR SEVERANCE AGREEMENT"). The Company and Employee desire to amend
and restate the Prior Severance Agreement in its entirety hereby.

         E. Certain capitalized terms used in the Agreement are defined in
Section 6 below.

         The parties hereto agree to amend and restate the Prior Severance
Agreement in its entirety as follows:

         1. TERM OF AGREEMENT. This Agreement shall terminate upon the date that
all obligations of the parties hereto with respect to this Agreement have been
satisfied.


<PAGE>

         2. AT-WILL EMPLOYMENT. The Company and the Employee acknowledge that
the Employee's employment is and shall continue to be at-will, as defined under
applicable law. If the Employee's employment terminates for any reason,
including (without limitation) any termination prior to a Change of Control, the
Employee shall not be entitled to any payments, benefits, damages, awards or
compensation other than as provided by this Agreement or as may otherwise be
available in accordance with the Company's established employee plans and
practices or pursuant to other agreements with the Company.

         3. STOCK VESTING ON CHANGE OF CONTROL.

                  (A) ACCELERATION UPON CHANGE OF CONTROL. Upon a Change of
Control, fifty percent (50%) of the Employee's options to purchase Common Stock
of the Company and/or shares of restricted stock of the Company that are
unvested as of the date of the Change of Control (the "UNVESTED SHARES") shall
immediately become vested.

                  (B) VESTING OF REMAINING UNVESTED SHARES. Upon a Change of
Control, the remainder of the Unvested Shares for which vesting was not
accelerated pursuant to Section 3(a) shall continue to vest at the same monthly
rate as prior to the Change of Control (i.e., if 200 shares vested per month
prior to the Change of Control, the remaining Unvested Shares will continue to
vest at the rate of 200 shares per month after the Change of Control) and in
accordance with the applicable stock option or restricted stock purchase
agreement.

         4.       CONSULTING ARRANGEMENT.

                  (A) TERMINATION FOLLOWING A CHANGE OF CONTROL. If the
Employee's employment terminates as a result of Involuntary Termination other
than for Cause at any time within twelve (12) months following a Change of
Control, then, subject to Section 6, the Employee and the Company shall enter
into a consulting arrangement on the following terms:

                           (1) CONSULTING ENGAGEMENT. Effective as of the
Termination Date, and subject to the terms of this Agreement, the Company agrees
to retain the Employee as a consultant to perform such services (the "CONSULTING
SERVICES") for the Company as may be reasonably requested from time to time by
an officer of the Company (the "CONSULTING ARRANGEMENT"). The term of this
Consulting Arrangement shall commence on the Termination Date and expire on the
earlier of (i) the date the employee is working as a salaried employee of or
consultant to another person, company or entity which is actually or potentially
in competition with any business conducted by the Company, as determined by the
Company in its sole discretion, (ii) at the Employee's option, the date the
Employee is working as a salaried employee of or consultant to another person,
company or entity, or (iii) 24 months following the Termination Date. As
consideration for the Employee's services under the Consulting Arrangement, the
Company shall pay in cash to Employee an amount equal to 1/12th of the
Employee's Annual Compensation on the last day of each full month following the
Termination Date during which the Consulting Arrangement is in effect. The
Employee's stock options and/or restricted stock shall continue to vest during
the term of the Consulting Arrangement pursuant to Section 3(b). Notwithstanding
the foregoing, the Consulting Arrangement may be terminated earlier by either
party upon five days written notice of termination if the other party


                                       -2-

<PAGE>

fails to cure any material breach of its obligations hereunder within 10 days
after receipt of notice specifying such breach.

                           (2) CONTINUED INSURANCE COVERAGE. Subject to the
provisions of this Section 4(a)(2), the Employee shall be entitled to one
hundred percent (100%) Company-paid health, dental and life insurance coverage
at the same level of coverage as was provided to such Employee immediately prior
to the Change of Control (the "COMPANY-PAID COVERAGE"). If such coverage
includes the Employee's dependents immediately prior to the Change of Control,
such dependents shall also be covered at Company expense. Company-Paid Coverage
shall continue until the earlier of (i) termination of the Consulting
Arrangement or (ii) the date that the Employee and his or her dependents become
covered under another employer's group health, dental or life insurance plans
that provide Employee and his or her dependents with comparable benefits and
levels of coverage. For purposes of Title X of the Consolidated Budget
Reconciliation Act of 1985 ("COBRA"), the date of the "qualifying event" for
Employee and his or her dependents shall be the date upon which the Company-Paid
Coverage terminates.

                  (B) VOLUNTARY RESIGNATION; TERMINATION FOR CAUSE. If the
Employee's employment terminates by reason of the Employee's voluntary
resignation (and is not an Involuntary Termination), or if the Employee is
terminated for Cause, then the Employee shall not be entitled to receive
payments for consulting services or other benefits under Section 4(a) except for
those (if any) as may then be established under the Company's then existing
severance and benefits plans and practices or pursuant to other agreements with
the Company.

                  (C) DISABILITY; DEATH. If the Company terminates the
Employee's employment as a result of the Employee's Disability, or such
Employee's employment is terminated due to the death of the Employee, then the
Employee shall not be entitled to receive payments for consulting services or
other benefits under Section 4(a) except for those (if any) as may then be
established under the Company's then existing severance and benefits plans and
practices or pursuant to other agreements with the Company.

                  (D) TERMINATION APART FROM CHANGE OF CONTROL. In the event the
Employee's employment is terminated for any reason, either prior to the
occurrence of a Change of Control or after the twelve-month period following a
Change of Control, then the Employee shall not be entitled to receive payments
for consulting services or other benefits under Section 4(a) except for those
(if any) as may then be established under the Company's existing severance and
benefits plans and practices or pursuant to other agreements with the Company.

         5. ATTORNEY FEES, COSTS AND EXPENSES. The Company shall promptly
reimburse Employee, on a monthly basis, for the reasonable attorney fees, costs
and expenses incurred by the Employee in connection with any action brought by
Employee to enforce his or her rights hereunder. In the event Employee is not
the prevailing party, determined without regard to whether or not the action
results in a final judgment, Employee shall repay such reimbursements.

         6. LIMITATION ON PAYMENTS. In the event that the payments and other
benefits provided for in this Agreement or otherwise payable to the Employee (i)
constitute


                                       -3-

<PAGE>

"parachute payments" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code"), and (ii) but for this
Section 6, would be subject to the excise tax imposed by Section 4999 of the
Code (or any corresponding provisions of state income tax law), then the
Employee's benefits under Section 4(a) shall be either

                  (a)      delivered in full, or

                  (b)      delivered as to such lesser extent which would result
in no portion of such benefits being subject to excise tax under Section 4999 of
the Code,

whichever of the foregoing amounts, taking into account the applicable federal,
state and local income taxes and the excise tax imposed by Section 4999, results
in the receipt by the Employee on an after-tax-basis, of the greater amount of
benefits, notwithstanding that all or some portion of such benefits may be
taxable under Section 4999 of the Code. Unless the Company and the Employee
otherwise agree in writing, any determination required under this Section 6
shall be made in writing by the Company's independent public accountants (the
"ACCOUNTANTS"), whose determination shall be conclusive and binding upon the
Employee and the Company for all purposes. For purposes of making the
calculations required by this Section 6, the Accountants may make reasonable
assumptions and approximations concerning applicable taxes and may rely on
reasonable, good faith interpretations concerning the application of Sections
280G and 4999 of the Code. The Company and the Employee shall furnish to the
Accountants such information and documents as the Accountants may reasonably
request in order to make a determination under this Section. The Company shall
bear all costs the Accountants may reasonably incur in connection with any
calculations contemplated by this Section 6. In the event that subsection (a)
above applies, then Employee shall be responsible for any excise taxes imposed
with respect to such benefits. In the event that subsection (b) above applies,
then each benefit provided hereunder shall be proportionately reduced to the
extent necessary to avoid imposition of such excise taxes.

         7. DEFINITION OF TERMS. The following terms used in this Agreement
shall have the following meanings:

                  (A) ANNUAL COMPENSATION. "ANNUAL COMPENSATION" means an amount
equal to (i) Employee's Company salary for the twelve months preceding the
Change of Control, and (ii) Employee's maximum target bonus for the year in
which the Change of Control occurs.

                  (B) CAUSE. "CAUSE" shall mean (i) any act of personal
dishonesty taken by the Employee in connection with his or her responsibilities
as an employee and intended to result in substantial personal enrichment of the
Employee, (ii) Employee's committing and being convicted of a felony, (iii) a
willful act by the Employee which constitutes gross misconduct and which is
injurious to the Company or an act of fraud by Employee against the Company, or
(iv) following delivery to the Employee of a written demand for performance from
the Company which describes the basis for the Company's belief that the Employee
has not substantially performed his or her duties, continued violations by the
Employee of the Employee's obligations to the Company which are demonstrably
willful and deliberate on the Employee's part.

<PAGE>

                  (C) CHANGE OF CONTROL. "CHANGE OF CONTROL" means the
occurrence of any of the following events:

                           (i) Any "PERSON" (as such term is used in Section
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) is or
becomes the "BENEFICIAL OWNER" (as defined in Rule 13d-3 under said Act),
directly or indirectly, of securities of the Company representing 50% or more of
the total voting power represented by the Company's then outstanding voting
securities; or

                           (ii) A change in the composition of the Board
occurring within a two-year period, as a result of which fewer than a majority
of the directors are Incumbent Directors. "INCUMBENT DIRECTORS" shall mean
directors who either (A) are directors of the Company elected at the annual
meeting of stockholders of the Company to be held on June 13, 1997, or (B) are
elected, or nominated for election, to the Board with the affirmative votes of
at least a majority of the Incumbent Directors at the time of such election or
nomination (but shall not include an individual whose election or nomination is
in connection with an actual or threatened proxy contest relating to the
election of directors to the Company); or

                           (iii) The stockholders of the Company approve a
merger or consolidation of the Company with any other corporation, other than a
merger or consolidation which would result in the voting securities of the
Company outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) at least fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity
outstanding immediately after such merger or consolidation or the stockholders
of the Company approve a plan of complete liquidation of the Company or an
agreement for the sale or disposition by the Company of all or substantially all
the Company's assets.

                  (D) DISABILITY. "DISABILITY" shall mean that the Employee has
been unable to perform his or her Company duties as the result of his or her
incapacity due to physical or mental illness, and such inability, at least 26
weeks after its commencement, is determined to be total and permanent by a
physician selected by the Company or its insurers and acceptable to the Employee
or the Employee's legal representative (such Agreement as to acceptability not
to be unreasonably withheld). Termination resulting from Disability may only be
effected after at least 30 days' written notice by the Company of its intention
to terminate the Employee's employment. In the event that the Employee resumes
the performance of substantially all of his or her duties hereunder before the
termination of his or her employment becomes effective, the notice of intent to
terminate shall automatically be deemed to have been revoked.

                  (E) INVOLUNTARY TERMINATION. "INVOLUNTARY TERMINATION" shall
mean (i) without the Employee's express written consent, the significant
reduction of the Employee's duties, authority or responsibilities, relative to
the Employee's duties, authority or responsibilities as in effect immediately
prior to such reduction, or the assignment to Employee of such reduced duties,
authority or responsibilities; (ii) without the Employee's express written
consent, a substantial reduction, without good business reasons, of the
facilities and prerequisites (including office space and location) available to
the Employee immediately prior to such reduction; (iii) a


                                       -5-

<PAGE>

reduction by the Company in the base salary of the Employee as in effect
immediately prior to such reduction; (iv) a material reduction by the Company
in the kind or level of employee benefits, including bonuses, to which the
Employee was entitled immediately prior to such reduction with the result
that the Employee's overall benefits package is significantly reduced; (v)
the relocation of the Employee to a facility or a location more than thirty
(30) miles from the Employee's then present location, without the Employee's
express written consent; (vi) any purported termination of the Employee by
the Company which is not effected for Disability or for Cause, or any
purported termination for which the grounds relied upon are not valid; (vii)
the failure of the Company to obtain the assumption of this Agreement by any
successors contemplated in Section 8(a) below; or (viii) any act or set of
facts or circumstances which would, under California case law or statute,
constitute a constructive termination of the Employee.

                  (F) TERMINATION DATE. "TERMINATION DATE" shall mean (i) if
this Agreement is terminated by the Company for Disability, thirty (30) days
after notice of termination is given to the Employee (provided that the Employee
shall not have returned to the performance of the Employee's duties on a
full-time basis during such thirty (30)-day period), (ii) if the Employee's
employment is terminated by the Company for any other reason, the date on which
a notice of termination is given, provided that if within thirty (30) days after
the Company gives the Employee notice of termination, the Employee notifies the
Company that a dispute exists concerning the termination or the benefits due
pursuant to this Agreement, then the Termination Date shall be the date on which
such dispute is finally determined, either by mutual written agreement of the
parties, or by a final judgment, order or decree of a court of competent
jurisdiction (the time for appeal therefrom having expired and no appeal having
been perfected), or (iii) if the Agreement is terminated by the Employee, the
date on which the Employee delivers the notice of termination to the Company.

         8.       SUCCESSORS.

                  (A) COMPANY'S SUCCESSORS. Any successor to the Company
(whether direct or indirect and whether by purchase, merger, consolidation,
liquidation or otherwise) to all or substantially all of the Company's business
and/or assets shall assume the obligations under this Agreement and agree
expressly to perform the obligations under this Agreement in the same manner and
to the same extent as the Company would be required to perform such obligations
in the absence of a succession. For all purposes under this Agreement, the term
"COMPANY" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this Section
8(a) or which becomes bound by the terms of this Agreement by operation of law.

                  (B) EMPLOYEE'S SUCCESSORS. The terms of this Agreement and all
rights of the Employee hereunder shall inure to the benefit of, and be
enforceable by, the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.

         9.       NOTICE.

                                       -6-

<PAGE>

                  (A) GENERAL. Notices and all other communications contemplated
by this Agreement shall be in writing and shall be deemed to have been duly
given when personally delivered or five (5) days after being mailed by U.S.
registered or certified mail, return receipt requested and postage prepaid. In
the case of the Employee, mailed notices shall be addressed to him or her at the
home address which he or she most recently communicated to the Company in
writing. In the case of the Company, mailed notices shall be addressed to its
corporate headquarters, and all notices shall be directed to the attention of
its Secretary.

                  (B) NOTICE OF TERMINATION. Any termination by the Company for
Cause or by the Employee as a result of a voluntary resignation and any
Involuntary Termination shall be communicated by a notice of termination to the
other party hereto given in accordance with Section 9(a) of this Agreement. Such
notice shall indicate the specific termination provision in this Agreement
relied upon, shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination under the provision so indicated, and
shall specify the termination date (which shall be not more than 30 days after
the giving of such notice). The failure by the Employee to include in the notice
any fact or circumstance which contributes to a showing of Involuntary
Termination shall not waive any right of the Employee hereunder or preclude the
Employee from asserting such fact or circumstance in enforcing his or her rights
hereunder.

         10.      MISCELLANEOUS PROVISIONS.

                  (A) NO DUTY TO MITIGATE. The Employee shall not be required to
mitigate the amount of any payment contemplated by this Agreement, nor shall any
such payment be reduced by any earnings that the Employee may receive from any
other source, subject to the termination provisions of Section 4(a)(1).

                  (B) WAIVER. No provision of this Agreement shall be modified,
waived or discharged unless the modification, waiver or discharge is agreed to
in writing and signed by the Employee and by an authorized officer of the
Company (other than the Employee). No waiver by either party of any breach of,
or of compliance with, any condition or provision of this Agreement by the other
party shall be considered a waiver of any other condition or provision or of the
same condition or provision at another time.

                  (C) WHOLE AGREEMENT. The Prior Severance Agreement is hereby
terminated, and this Agreement supersedes the Prior Severance Agreement in its
entirety. This Agreement represents the entire agreement between the Employee
and the Company with respect to the matters set forth herein. No agreements,
representations or understandings (whether oral or written and whether express
or implied) which are not expressly set forth in this Agreement have been made
or entered into by either party with respect to the subject matter hereof.

                  (D) CHOICE OF LAW. The validity, interpretation, construction
and performance of this Agreement shall be governed by the laws of the State of
California as applied to agreements entered into and performed within California
solely by residents of that state.


                                       -7-

<PAGE>

                  (E) SEVERABILITY. The invalidity or unenforceability of any
provision or provisions of this Agreement shall not affect the validity or
enforceability of any other provision hereof, which shall remain in full force
and effect.

                  (F) WITHHOLDING. All payments made pursuant to this Agreement
will be subject to withholding of applicable income and employment taxes.

                  (G) COUNTERPARTS. This Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which
together will constitute one and the same instrument.


                                       -8-

         IN WITNESS WHEREOF, each of the parties has executed this Agreement, in
the case of the Company by its duly authorized officer, as of the date set forth
above.
