OVERVIEW

Sync Research, Inc. ("Sync" or the "Company") develops, manufactures,
markets and supports wide-area network ("WAN") access, internetworking and
management solutions that enable customers to more reliably deploy
business-critical applications over frame relay and other public switched
virtual network ("PSVN") services.

As a result of the worldwide growth in data bandwidth requirements, the
telecommunications industry has undergone significant reform causing the
transformation of traditional carriers and the birth of a new generation of
geographically and market aligned value-added carriers and service providers,
collectively referred to as "Service Providers." In an effort to develop new
revenue sources and improve competitiveness, many of these Service Providers
provide data services based on frame relay, an efficient, low-latency,
frame-switched WAN protocol. Frame relay has experienced rapid growth as a PSVN
service due to its speed and economy, 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,
intelligent, PSVN 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.

Sync has developed a portfolio of products that provide end users and
service providers with innovative WAN access and management solutions engineered
to support mission-critical applications over frame relay and other PSVN
services. The Company's FrameNode-TM- line of multi-service frame relay access
devices ("FRADs") and frame relay access routers enables the migration of
embedded SNA leased line networks to frame relay, as well as the convergence of
SNA and client/server branch applications across frame relay networks. Sync's
circuit management solutions represent an emerging product category consisting
of WAN probes and application software that improves the availability and
performance of frame relay and other PSVN services 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 comprise frame relay and other digital and
switched services.

Today, most mainframe based data networks use expensive private 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. As both an SNA internetworking and frame relay access pioneer, the
Company was an early developer of SNA-over-frame relay and SNA and client/server
convergence solutions.

Sync continues to follow a leveraged sales strategy for its products,
utilizing 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, Pacific Bell Network
Integration ("PacBell"), Sprint Communications Company ("Sprint"), MCI
Communications Corporation ("MCI"), Intermedia Communications, Inc.
("Intermedia Communications"), Electronic Data Systems, Diebold, and Wang
Global. The Company believes that its partnerships are well-suited to serve
the needs of middle and upper market customers. The Company utilizes a
distribution and value-added reseller ("VAR") channel as the primary
distribution channel for its digital transmission products. Sales through
this channel have decreased over the last two years due to increased
competition, price decreases and focus on end-user and large partner
activities.

Sync maintains international sales and operations offices in Europe
(Frankfurt, Germany; Paris, France and London, U.K.) and relationships with
its channel partners to support its worldwide sales efforts.

INDUSTRY BACKGROUND

RELIANCE ON SNA FOR BUSINESS CRITICAL APPLICATIONS

Over the past few decades, organizations have predominantly performed
their business-critical data processing on IBM mainframe systems. These
transaction-oriented data processing applications have traditionally
supported such critical functions as branch banking, credit transactions,
retail point-of-sale transactions 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 the prevalent
network architecture for corporate wide-area networks since the late 1970s.
Industry analysts have estimated that there are approximately 50,000 IBM SNA
networks worldwide.

EMERGENCE OF IP AND CLIENT/SERVER COMPUTING

In the late 1980s, a new architecture for information processing called
"client/server" computing emerged, fueled by the growing intelligence in
desktop computers, 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 physically and logically
parallel the traditional leased-line hub and spoke model of the mainframe SNA
network, with centralized server "farms" mimicking mainframe data centers.

Sync believes that SNA and client/server architectures, each with
advantages for certain business applications, will continue to coexist. Thus,
certain organizations may be required to maintain two separate networks,
resulting in duplication of WAN and equipment costs, network management and
support personnel, as well as increased operational complexity.

PARADIGM SHIFT TO PUBLIC SWITCHED VIRTUAL NETWORK SERVICES

Continuing deregulation and reformation within the worldwide
telecommunications market has resulted in a dramatic increase in the number
of traditional and non-traditional carriers and service providers including
IXCs, Local Exchange Carriers ("LECs"), Competitive Local Exchange Carriers
("CLECs"), Network Service Providers ("NSPs") and Internetwork Service
Provider ("ISPs") and other companies that outsource networking and
telecommunications support and services. Sync refers to these organizations
collectively as "Service Providers." In order to differentiate their services
and remain competitive, Service Providers have deployed a number of data
transport networks based on packet and cell switched


2



technologies; specifically frame relay, Internet Protocol ("IP") and ATM.
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, effectively "out-tasking" WAN
planning, provisioning and management to their Service Provider. Many Service
Providers have taken the WAN "out-tasking" model to the next step by creating
adjunct services that take over end-to-end management of the End User's WAN
and, in some instances, even remote branch LAN. These services often bundle
telecommunications services with the components necessary to connect customer
sites to the network.

The shift from leased lines to PSVN 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 PSVN. In turn, Service
Providers have increased responsibility for end user application performance,
especially in connection with managed network services ("MNS") offerings.

THE SYNC SOLUTION

Sync is a provider of WAN access, internetworking and management
products that enable business-critical SNA and client/server applications to
be safely deployed over frame relay or other PSVN 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. To reach these customers, Sync has entered into certain
relationships with network equipment and service providers that serve the SNA
customer base and focuses its end user sales force on targeting middle market
mainframe reliant customers.

PRODUCTS

Sync has continued to focus almost exclusively on the growing frame
relay marketplace. The Company is currently assessing its future product
direction and believes that its next generation product platform may provide
support for new protocols including ATM and Asyncronous Digital Subscriber
Line ("ADSL"). 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- family of FRADs and frame relay
access routers reduces 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's
FrameNode-Registered Trademark- has won various industry awards over the past
several years for its measured performance in these areas. In independent
testing, the FrameNode-Registered Trademark- has outperformed frame
relay-equipped routers and FRADs from the industry's leading networking
companies in handling both SNA and client/server (IP/IPX) branch traffic.

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 growing number of large IBM-centric customers, such as Bear Sterns,
First Union Corporation ("First Union"), Electronic Data Systems, VISA
International and Bank of America Corporation ("B of A"), have selected Sync
and its market partners as their frame relay solution provider. Several
service providers, including Sprint, have also chosen the
FrameNode-Registered Trademark- for their MNS offerings.

CIRCUIT MANAGEMENT SOLUTIONS


3



Sync's circuit management technology consists of a series of WAN
monitoring probes and graphical applications. Together, these components
allow End Users and Service Providers to improve network availability and
performance and reduce network operating costs by enhancing problem
isolation, identification and troubleshooting and instrumenting their frame
relay networks with 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.

Sync's digital transmission products have been installed by Service
Providers in the United States, Korea, Canada, Mexico and other markets as
infrastructure connectivity for leased line, frame relay, cellular and
internet service offerings.

PRODUCT STRATEGY

Sync has developed a multifaceted product strategy that the Company
believes significantly expands its total addressable market by concurrently
participating in three related market segments that are key to frame relay
(and ISP) connectivity: frame relay access, frame relay circuit and
service-level management, and high-speed digital transmission. Beginning in
1999, Sync plans to introduce significant new product capabilities. The
first of these new products will result from the physical integration of its
frame relay access products, circuit management and digital transmission
products with alternative backup capabilities, such as ISDN, into one
combined solution. These products are expected to provide a very cost
effective solution that enhances high availability for customers. The first
of these products is scheduled to be available during the second quarter of
1999. Going forward, Sync will plan to continue to leverage its technology
strengths through the development of a product that may include support for
higher speeds (such as T3+, and the new standards outlined by FRF.14); new
technology protocols (ATM and ADSL); transmission services (encryption and
compression) and back-up and redundancy features creating bandwidth on demand
using, for example, Switched Virtual Circuits (SVCs) and ISDN, etc. This next
generation of products is expected to be available during the first half of
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

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.

ENTERPRISE END USER CUSTOMERS

Industry analysts have estimated that there are approximately 50,000 IBM
SNA networks worldwide. Sync's strategy is to provide a comprehensive product
solution for safely migrating mission-critical SNA and client/server
applications to frame relay. The Company believes that advantages to its
customers include improved network reliability and determinism, 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 competitive environment for
these large enterprises is significant, especially in light of the recent
mergers in the telecommunications equipment industry. Accordingly, Sync's
focus is at the middle market tier of companies with 25 to 500 branch sites.
Many of these companies have significant mission critical data networking
needs, but the Company believes they are currently under served by the larger
telecommunications equipment companies.

SERVICE PROVIDERS

The FrameNode-Registered Trademark- is designed to be an optimal CPE
solution for managed service offerings. In addition to its broad support for
SNA, legacy, and IP/IPX protocols, it includes extensive end-to-end network
management capabilities. Sync believes that these capabilities allow for 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 client/server applications, Sync believes they
will not be willing to give up the stable, deterministic, resilient and
management-rich attributes of their SNA leased line networks. The goal of
Sync's circuit management technology is to equip customers and service
providers with the management capabilities necessary to safely migrate
business-critical SNA and client/server applications to frame relay and other
PSVN services without compromising on network performance and availability
requirements.

CUSTOMER BASE

The Company's products are used in a wide variety of industries
worldwide. Sync's customer base continues to expand and today includes a
broad mix of major End Users and Service Providers. The following
organizations are among the customers that have purchased products directly

SALES AND PARTNER CHANNELS


5



The Company's sales and channel strategy includes deployment through
channel partners, distributors and a direct sales force, both in North
America and overseas. The Company has from time to time entered into channel
partnerships with selected internetworking companies, as well as carriers. In
addition to its relationships with channel partners and other resellers, the
Company continues to maintain a direct sales force to ensure close customer
contact and facilitate channel field sales engagement.

CHANNEL PARTNERS AND OTHER RESELLERS

The Company's sales and marketing strategy focuses on establishing
channel partnerships with selected, leading networking companies and carriers
that are attempting to better serve the SNA customer base. Sync and its
channel partners work closely together in various activities, including
collaborative marketing efforts, joint sales calls, field training and
support and custom product development. The Company currently maintains OEM,
marketing and sales arrangements with Service Providers such as Sprint, MCI,
Ameritech, PacBell, Appitude, Inc., Wang Global, and Intermedia
Communications. The Company intends to maintain direct sales, marketing and
systems engineering activities in order to drive demand for Sync products and
support channel partners.

IBM: IBM is the developer of the SNA network architecture. Since 1995,
IBM has sold Sync's FrameNode-Registered Trademark- product family under the
name IBM Nways 2218. The agreement between IBM and Sync expired in March 1999
and is not expected to be renewed. Sales to IBM accounted for 14.1%,16.5% and
4.9% of the Company's net revenues in 1998, 1997 and 1996, respectively.

3COM CORPORATION: 3Com offers a broad range of global networking
solutions including routers, hubs, ISDN equipment and network adapters.
Concurrently with an equity investment in the Company in April 1994, 3Com and
Sync entered into a private label and resale relationship, pursuant to which
Sync developed certain custom products incorporating certain early generation
Sync technology. Sales to 3Com accounted for 2.6%, 6.5% and 19.2% of the
Company's net revenues in 1998, 1997 and 1996, respectively. 3Com recently
announced its intention to discontinue its support for its products purchased
from Sync. Accordingly, the Company believes that revenue derived from sales
to 3Com will remain low.

SERVICE PROVIDERS: Sync has developed FrameNode-Registered Trademark-
and Frap CPE resale and bundled managed service relationships with a number
of service providers, including MCI, Sprint, and Intermedia Communications.
In a "managed service" program, the carrier combines Sync's networking
products with the carrier's own wide-area network service offering. The
carrier installs, deploys, and manages the customer's network, providing a
single service invoice monthly. This service allows customers to avoid the
expense of selecting, purchasing, deploying and managing the vendor equipment
and carrier circuits that comprise its network infrastructure.

OTHER RESELLERS: The company sells its products through other
resellers, in addition to its channel partners, including distributors and
VARs. The Company plans to develop and expand its reseller channel to
accommodate, in particular, its line of WAN access, transmission and
management product lines.

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


6



Channel Partners and Other Resellers" and "Intense Competition."

DIRECT SALES

In addition to its channel partner strategy, Sync maintains a direct
sales organization to promote the Company's products and to ensure direct
contact with the Company's current and potential customers. The primary roles
of the Company's sales force are (i) to assist end user customers in
addressing complex network problems and (ii) to differentiate the features
and capabilities of the Company's products from competitive offerings and
(iii) provide support to channel partners. In addition, the Company believes
that its investment in direct sales enables the Company to monitor changing
customer requirements. As of December 31, 1998, the Company had 18 domestic
field sales and support personnel currently operating out of locations in 14
states. First Union Bank, a direct sales customer, respresented $4.6 million
or 18.5% in 1998, $1.5 million or 6.5% in 1997 of the Company's net revenues.

INTERNATIONAL SALES

Sales to customers outside of the United States accounted for
approximately $1.7 million, $4.5 million and $4.6 million, or 6.9%, 19.1% and
12.7% of the Company's net revenues in 1998, 1997 and 1996, respectively.
However, these percentages may understate sales of the Company's products to
international end users because certain of the Company's U.S. based channel
partners market the Company's products abroad. The Company expects that
international sales may represent an important percentage of net revenues in
future periods. The near-term outlook on the Company's sales to the Pacific
Rim, which represented approximately 3.7% of the Company's 1998 net revenues,
remains uncertain.

The Company currently expects the frame relay equipment market outside
of the United States to grow during the next several years. The European and
Canadian markets represent large growing market opportunities and the primary
focus for Sync's international business thrust. Although there are
significant long-term potential opportunities in the Pacific Rim countries,
sales in this region have been impacted by the continued currency crisis.

The Company has designed its products and established its marketing and
sales channels to address the global market opportunities for frame relay
access and circuit management products. The Company believes that there is a
large potential international market for its products and intends to address
this market in the future increasingly through its channel partners, many of
which have a well-established international presence and reputation. Sync
believes its strategy for international expansion will allow the Company to
participate in these emerging growth markets.

The Company maintains international sales offices in Frankfurt, Germany,
Paris, France and London, UK. The Company's sales efforts in the Pacific Rim
are conducted through its existing relationships with partners and resellers.

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 sold directly in
the United States 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 who
work closely with the Company's channel partners and direct sales personnel
to assist End Users with pre- 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


7



sales personnel by providing telephone support and remote access to customer
installations through the Company's technical assistance centers in Irvine,
California and Norton, Massachusetts. Remote access is accomplished either
through a digital dial-up network connection directly to a customer's
installation or through a modem connection to the control port of the
customer's system. This connection allows Company representatives to remotely
analyze and correct software, installation and configuration problems. The
Company also offers on-site installation and technical assistance 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 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 works closely with channel partners and
resellers, end user customers and market research organizations to monitor
changes in the marketplace. The Company intends to support industry standards
and to continue to support emerging wide-area networking protocols.

The Company's research and development expenditures aggregated $7.4
million, $7.2 million and $7.7 million in 1998, 1997 and 1996, respectively.
At December 31, 1998, 44 full-time employees were engaged in research and
product development. In 1998, the Company implemented significant expense
reductions with the goal of enabling the Company to achieve profitability at
lower revenues. These expense reductions included a reduction in outside
engineering consulting costs available to support the Company's research and
development efforts. The Company believes that it will be able to meet its
development plans within the cost structure set forth in the recent expense
reduction program. 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 development efforts on creating significant
new product capabilities. The first of these new products will result from
the physical integration of its frame relay access products, circuit
management and digital transmission products with alternative backup
capabilities, such as ISDN into one combined solution. This product is
expected to provide a cost effective solution that enhances high availability
through bandwidth-on-demand functionality for our customers. The product is
planned to be available during the second quarter of 1999. Going forward,
Sync plans to continue to leverage its technology strengths through the
development of a product that may include support for higher speeds (such as
T3+, and the new standards outlined by FRF.14); new technology protocols
(ATM, ADSL, IP); transmission services (encryption and compression) and
back-up and redundancy features creating bandwidth on demand using SVCs and
ISDN, etc. This next generation of products is expected to be available
during the first half of 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
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 has entered into arrangements with contract
manufacturers to outsource substantial portions of its procurement, assembly
and system integration operations.


8



The Company designs substantially all of the hardware subassemblies for
its products. Outside subcontractors are used for subassembly manufacturing.
The Company installs its proprietary software into the electronically
erasable programmable read only memory ("EEPROM") of its systems in order to
configure products to meet customer needs and to maintain quality control and
system security.

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

In addition to outsourcing, the Company attempts to reduce manufacturing
costs by minimizing single and limited source and custom parts, and designing
in capability for automated assembly and testing. The manufacturing process
enables the Company to configure hardware and software in combinations to
meet a wide variety of individual customer requirements.

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, 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 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"),
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, IBM and the Company's other 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 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


10



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, 1998, the Company employed 143 persons, including 44
in engineering, 38 in sales and marketing, 46 in operations and 15 in finance
and administration. During 1997 and 1998, the Company initiated cost
reductions programs that included a reduction in workforce. 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."

Directors and will be dependent upon the Company's financial condition,
results of operations, capital requirements and such other factors as the
Board of Directors deems relevant.

USE OF PROCEEDS

In connection with its initial public offering in 1995, the Company
filed a Registration Statement on Form S-1, SEC File No. 33-96910 (the
"REGISTRATION STATEMENT"), which was declared effective by the Commission on
November 8, 1995. Pursuant to the Registration Statement, the Company
registered and sold 2,585,000 shares of its Common Stock, $0.001 par value
per share, for its own account. The offering was completed on November 9,
1995. The aggregate offering price of the registered shares was $51,700,000.
The managing underwriters of the offering were BancBoston Robertson, Stephens
(formerly Robertson, Stephens & Company), BT Alex. Brown (formerly Alex.
Brown & Sons Incorporated) and Dain Rauscher Wessels (formerly Wessels,
Arnold & Henderson). From November 9, 1995 to December 31, 1998, the Company
incurred the following expenses in connection with the offering:

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

OVERVIEW

Sync commenced operations in 1981 and funded operations through 1988
with revenue from communications software consulting and custom product
development for equipment vendors and large end-users. The Company shipped
its first commercial WAN product in 1989. In 1991, Sync released its first
Conversion Node and frame relay access products. Sync follows a leveraged
sales strategy for its FRAD and circuit management products, utilizing
resellers, distributors, OEM partners and carriers as delivery channels for
its products. Current partners include PacBell, Sprint, MCI, Intermedia
Communications, Electronic Data Systems, Diebold and Wang Global. The Company
believes that partnerships are well suited to serve the needs of middle and
upper market customers. The Company has also sold its products through OEM
relationships with IBM and 3Com among others. The agreement between IBM and
Sync expired in March 1999 and is not expected to be renewed. 3Com has
discontinued its support for Sync's products and accordingly, the Company
believes that revenue derived from sales to IBM and 3Com will decline and
remain low.

On August 23, 1996, Sync acquired TyLink Corporation, pursuant to a
merger of a wholly-owned subsidiary of the Company with and into TyLink (the
"Merger"). In the Merger, the Company exchanged 2,148,168 shares of its
common stock for all of the outstanding shares of TyLink common and Series A
preferred stock and reserved 423,155 shares of Sync common stock for issuance
upon exercise of TyLink options, which were assumed by the Company. In
addition, Sync acquired all of the issued and outstanding Tylink Series B
preferred stock for $4 million in cash and 208,677 shares of Sync common
stock. The Merger has been accounted for as a pooling of interests.
Accordingly, the accompanying financial statements reflect the combination of
Sync and TyLink for all periods presented.

In December 1998 and during 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 Sync'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, including
in recent years, operating losses of $16.3 million in 1998, $18.0 million in
1997 and $11.6 million in 1996. As of December 31, 1998, the Company had an
accumulated deficit of approximately $54.4 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, and
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 Sync'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; announcements by IBM relating to products, services or pricing
relevant to the Company; the

16



rate of migration of large IBM customers to frame relay; production or
quality problems; changes in material costs; impact of Year 2000 compliance
problems on the networking industry and the Company's customers, 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 continue to account for
a majority 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 or 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. Further, due to the Company's focus on its
channel partner marketing strategy, the Company's revenues in any period are
highly dependent upon the sales efforts and success of Sync's channel
partners and other resellers, which are not within the control of the
Company. There can be no assurance 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 alternative networking
solutions or that Sync's channel partners and other resellers will continue
to offer the Company's products. A significant portion of the Company's
expenses are relatively fixed in advance, based in large part on the
Company's forecasts of future sales. 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.

DEPENDENCE ON THE IBM CUSTOMER BASE

The Company's frame relay access products are targeted at the large
installed base of IBM customers utilizing SNA networks. Thus, the Company
faces the risks associated with a relatively concentrated customer base,
including the possibility that larger IBM customers may migrate to frame
relay at a slower-than-expected rate, if at all, and the possibility that IBM
customers may purchase IBM-sponsored frame relay products other than Sync
products or other suppliers' products. Since 1995, IBM has sold Sync's
FrameNode-Registered Trademark- product family under the name IBM Nways 2218.
The agreement between IBM and Sync expired in March 1999 and is not expected
to be renewed. Sales to IBM respectively accounted for 14.1%, 16.5% and 4.9%
of the Company's net revenues in 1998, 1997 and 1996, respectively, and are
expected to decline in 1999. 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, or that IBM will not
endorse the products of competitors or networking solutions not offered by
the Company. Any of these events could have a material adverse effect on the
Company's business, operating results and financial condition.

UNCERTAIN MARKET ACCEPTANCE OF FRAME RELAY FOR MISSION-CRITICAL APPLICATIONS

During 1998, sales of frame relay access products, which enable SNA and
client/server internet-working over frame relay, represented approximately
49% of the Company's net revenues. The market for SNA-over-frame relay
products is relatively new and still evolving. 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. 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


17



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.

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 other products 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, announcements by IBM relating to
products, 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 those of
certain of its current and potential competitors. The 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 majority of the Company's net
revenues, including virtually all of its sales outside of the United States.
Sales through channel partners and other resellers accounted for 62.5%,
67.0%, and 85.7% of net revenues of the Company in 1998, 1997 and 1996,
respectively. Current partners include PacBell, Sprint, MCI, Intermedia
Communications, Electronic Data Systems, Diebold and Wang Global. The Company
believes that partnerships are well-suited to serve the needs of middle and
upper market customers. The Company has also sold its products through OEM
relationships with IBM and 3Com among others. The agreement between IBM and
Sync expired in March 1999 and is not expected to be renewed. Sales to IBM
accounted for 14.1%, 16.5% and 4.9% of the Company's net revenues in 1998,
1997 and 1996, respectively. Sales to 3Com accounted for 2.6%, 6.5% and 19.2%
of the Company's net revenues in 1998, 1997 and 1996, respectively. 3Com has
discontinued its support for Sync's products and accordingly, the Company
believes that revenue derived from sales to 3Com and IBM will decline and
remain low.

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 manufacturing rights and access to source code upon
the occurrence of specified conditions or defaults.

Certain of the Company's channel partners offer alternative solutions,
designed by themselves or third parties, for SNA internetworking or have
pre-existing relationships with current or potential competitors of the
Company. 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. Many of the Company's resellers
offer competitive products manufactured either by third parties or by
themselves.

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 significant
portion of the Company's net revenues, gross profit as a percentage of net
revenues


18



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 Sync'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 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 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 financia condition.

PRODUCT ERRORS

Products as complex as those offered by the Company may contain
undetected software or hardware errors when first introduced or as new
versions are released. Such errors have occurred in the past, and there can
be no assurance that, despite testing by the Company and by current and
potential customers, errors will not be found in new or enhanced products
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 Sync's 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 ISG and
Cabletron; and circuit management and digital transmission providers such as
Visual Networks, Digital Link, Racal, AT&T Paradyne and Adtran, among others.
Potential competitors include other internetworking and WAN


19



access and transmission companies, frame relay switch providers, IBM and the
Company's other channel partners. Certain of these companies have recently
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 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 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 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. 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. There can be
no assurance that the Company wil 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 entered into arrangements with contract
manufacturers to outsource substantial portions of its procurement, assembly
and system integration 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 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 in
a supplier, increase in required lead times, increase in price of component
parts, 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. 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 6.9%, 19.1% and 12.7% of the Company's net revenues in 1998,
1997 and 1996, respectively. However, these percentages may understate sales
of the Company's products to international end users because certain of the
Company's U.S-based channel partners market the Company's products abroad.
The Company expects that international sales may represent an important
percentage of net revenues in future periods. The near-term outlook on the
Company's sales to the Pacific Rim, which represented approximately 3.7% of
the Company's net revenues in 1998 and approximately 14.2% of the Company's
net revenues in 1997, remains uncertain.

Historically, the Company's international sales have been conducted
primarily through independent country-specific distributors. The Company
intends to continue to market its products in foreign countries in the future
through its channel partners. Failure of these 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. The 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, as
has occurred recently in several Asian markets, 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, currency exchange fluctuations, 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.

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 in the future relative to tariffs for dedicated
leased lines, the cost-effectiveness of the Company's


21



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 telecommunications authorities in various countries
as well as with recommendations of the Consultative Committee on
International Telegraph and Telephony. In addition, carriers require that
equipment connected to their networks comply with their own standards, which
in part reflect their currently installed equipment. Some public carriers
have installed equipment that does not fully comply with current industry
standards, and this noncompliance must be addressed in the design of the
Company's products. 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 management, sales, marketing, research and
development and manufacturing 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, and
development engineers. 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 1998, the Company implemented significant
expense reductions, including reductions in force, with the goal of enabling
the Company to achieve profitability at lower revenues. During 1998, the
Company also experienced significant turnover in the composition of its
executive officers. Two of the current four executive officers, including
the President and Chief Executive Officer, 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.

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 National
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
accordance with the notification, the Company has 90 days from the date of
the letter to cure such deficiency by having a minimum closing bid price of
its common stock equal to or greater than $1.00 per share for ten
consecutive trading days. As of March 15, 1999, the Company has not been able
to cure this deficiency. The Company's management is currently considering
alternative strategies for meeting the minimum listing requirements
including, repurchasing additional shares of stock under its stock repurchase
program, restructuring the


22



capital structure of the Company or raising additional capital. There can be
no assurance that the Company will be successful in meeting the minimum bid
listing requirements or that in the future it will not meet this or other
listing requirements. Any such inability could have a material adverse effect
the liquidity of the Company's common stock and on the Company's business,
operating results and financial condition.

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 prsent
plan to issue shares of preferred stock.

RESULTS OF OPERATIONS

COMPARISON OF 1998 AND 1997 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.

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):



1998 % 1997 %
-------- ------ -------- ------

Frame relay access products ........ $12,145 49.2% $10,011 43.0%
Circuit management products ........ 5,344 21.6 4,847 20.8
Transmission products .............. 2,041 8.3 4,394 18.9
Other .............................. 5,172 20.9 4,004 17.3
------- ----- ------- -----
$24,702 100.0% $23,256 100.0%
------- ------ ------- ------
------- ------ ------- ------


The increase in revenues of frame relay access and circuit management
products and other, consisting primarily of service, 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.


23



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. The agreement between IBM and Sync expired in March 1999 and
is not expected to be renewed. Sales to IBM are expected to decline in 1999.
The Company expects that average selling prices will continue to decline and
that sales through channel partners and other resellers will continue to
account for a majority of net revenues; however, the mix of sales among
channel partners and other resellers may change from period to period.

International sales accounted for 6.9% of net revenues in 1998, as
compared to 19.1% of net revenues in 1997. The Company expects that
international sales will continue to represent an important percentage of net
revenues in future periods. While Asian sales remained weak in 1998 due to
economic conditions in that region, European sales continued to grow slowly.
The near-term outlook on the Company's sales to the Pacific Rim, which
represented 3.7% and 14.2% of the Company's 1998 and 1997 net revenues,
respectively, remains uncertain.

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 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 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 increased slightly to $7.4 million for the
year ended December 31, 1998, from $7.2 million for the year ended December
31, 1997.

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 $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 headcount reductions.

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 $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.

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

24




ACCRUAL ACCRUAL
DESCRIPTION AT 12/31/97 CHARGE ACTIVITY AT 12/31/98
----------- ----------- ------ -------- -----------

Severance and related expenses ... $354 $1,210 $ (710) $ 854
Idle and excess facility charges
and write-off of assets........ 9 1,547 (446) 1,110
Other non-recurring charges ...... 9 95 (92) 12
---- ------ ------- ------
Total ............................ $372 $2,852 $(1,248) $1,976
---- ------ ------- ------
---- ------ ------- ------


In 1998, the Company completed its 1997 expense reduction program
activities. The Company expects all 1998 expense reduction program activities
will be substantially completed during fiscal 1999. The Company will continue
to evaluate and may adjust its organization and cost structure.

The Company recorded deferred compensation of $644,000 during 1995 for
the difference between the option exercise price or restricted stock price
and the deemed fair value of the Company's common stock for options granted
and restricted stock sold in 1995. The deferred compensation is being
amortized to operating expense and cost of sales over the related 48 month
vesting period of the shares and will, therefore, continue to have an adverse
effect on the Company's results of operations. Included in operating expenses
and cost of sales for the year ended December 31, 1998 were $27,000 of such
expenses, as compared to $79,000 for the year ended December 31, 1997.

Net interest income was $0.9 million for the year ended December 31,
1998, as compared to $1.5 million in the year ended December 31, 1997. 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 1998 represented minimum
state taxes. There were no provisions for income taxes in 1997.

COMPARISON OF 1997 AND 1996 RESULTS

NET REVENUES. Net revenues in 1997 were $23.3 million, a decrease from
the net revenues of $36.3 million in 1996. The lower net revenues in 1997
reflected decreased sales volumes in all of the Company's major product lines
and lower average selling prices partially offset by an increase in service
revenues. Net revenues by product group for the years ended December 31, 1997
and 1996 were as follows ($ in thousands):



1997 % 1996 %
-------- ------ -------- ------

Frame relay access products ......... $10,011 43.0% $14,214 39.1%
Circuit management products ......... 4,847 20.8 7,036 19.4
Transmission products ............... 4,394 18.9 6,348 17.5
Other ............................... 4,004 17.3 8,748 24.0
------- ------ ------- ------
$23,256 100.0% $36,346 100.0%
------- ------ ------- ------
------- ------ ------- ------


The shift in revenues to frame relay access and circuit management
products from other products was consistent with the Company's expected
change in product mix from its older product offerings.

The decrease in net revenues from sales of frame relay access products
during 1997 as compared to 1996 was, in part, due to the loss of Racal and
NET as channel partners. Racal and NET, which aggregated to more than 10% of
the Company's 1996 revenues, decreased to less than 1% of 1997 revenues, as
they developed competing products and ceased purchasing frame relay products
from the Company. Also contributing to this change was a reduction in sales
to 3Com, primarily older legacy


25




products, which represented $1.0 and $5.0 million of the Company's frame
relay access product revenues in 1997 and 1996, respectively.

The percentage of net revenues represented by sales through channel
partners and other resellers declined to 67.0% in 1997 from 85.7% in 1996.
The Company expects that average selling prices will continue to decline and
that sales through channel partners and other resellers will continue to
account for a majority of net revenues; however, the mix of sales among
channel partners and other resellers may change from period to period.

International sales accounted for 19.1% of net revenues in 1997, as
compared to 12.7% of net revenues in 1996. Sales to the Pacific Rim
represented 14.2% of the Company's 1997 net revenues.

GROSS PROFIT. Gross profit decreased to $8.5 million for 1997 from
$16.4 million in 1996 due primarily to lower sales volumes. Gross profit as a
percentage of net revenues decreased to 36.7% for the year ended December 31,
1997 from 45.0% for the year ended December 31, 1996, due primarily to lower
sales volumes which resulted in lower absorption of manufacturing costs, a
significant portion of which are primarily fixed in nature, increased
expenditures to support service activities, increased sales to IBM at higher
discounts than encountered in other channels and lower average selling prices.

OPERATING EXPENSES. Research and development expenses decreased to $7.2
million for the year ended December 31, 1997, from $7.7 million for the year
ended December 31, 1996. The decreased expenses in 1997 were primarily due to
the Company's cost reduction programs implemented in March 1997 and September
1997.

Selling and marketing expenses decreased to $14.3 million for the year
ended December 31, 1997 from $14.5 million for the year ended December 31,
1996. The decreased expenses resulted primarily from sales and marketing
headcount reductions as part of the Company's 1997 cost reduction programs.

General and administrative expenditures decreased to $3.7 million for
the year ended December 31, 1997, as compared to $5.8 million for the year
ended December 31, 1996. The decrease in general and administrative expenses
was primarily due to the Company's 1997 cost reduction programs and reflected
$1.3 million in expenditures incurred in connection with the Merger of Sync
and TyLink in 1996 for which no similar cost was incurred in 1997.

In March 1997 and September 1997, the Company implemented various cost
reduction programs in order to improve its results of operations. The
expenses associated with these programs aggregated approximately $1.2 million
and consisted primarily of severance and related headcount reduction
activities and to a lesser extent lease termination costs related to
redundant facilities.

Included in operating expenses and cost of sales for the year ended
December 31, 1997 were $79,000 of deferred compensation expenses, as compared
to $265,000 for the year ended December 31, 1996.

Net interest income was $1.5 million for the year ended December 31,
1997, as compared to $2.2 million in the year ended December 31, 1996. The
decrease in interest income was primarily due to the Company's lower cash
balances resulting from the utilization of cash to fund the Company's
operating activities.

INCOME TAXES. There was no provision for income tax in 1997. The
provision for income taxes in 1996 represented minimum state taxes.

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. As a result, errors or system failures could result if these
systems and applications are not corrected or replaced prior to the year
2000. The Company continues to evaluate the impact of the "Year 2000" issue
upon its products, support systems and overall business.

The Company has defined Year 2000 compliance using the British Standards
Institute (BSI) definition. The BSI DISC PD2000-1 definition appropriately
provides that Year 2000 compliance shall mean that neither product
performance nor functionality is affected by dates prior to, during and after
the year 2000. The Company has either internally or in collaboration with
certain of its suppliers and customers evaluated, tested and verified the
Year 2000 compliance of all of its current product offerings. The Company
believes that several of its discontinued conversion and frame relay products
are not Year 2000 compliant and the Company currently does not plan to update
these products. However, the Company offers upgrade programs to its customers
of most of these non-compliant discontinued products. Certain of the
Company's products rely on date information from other devices resident in
the networks in which they operate. Thus, any Year 2000 problems within these
third party networking products could cause the Company's products not to
work accurately or cause disruption in their operation.

The Company relies on a number of computer systems and applications to
operate and monitor all major aspects of its business. The Company has
evaluated all of its business critical systems internal information and
non-information systems and most of its non-critical systems through
inquiries with the manufacturers of such systems and testing or the
completion of other verification procedures. Substantially all of the
Company's critical systems have been verified to meet the Company's Year 2000
requirements and the Company's non-critical systems are expected to be made
fully compliant by December 31, 1999.The Company believes that several
manufacturers of the Company's systems have already updated their products to
comply with the Year 2000 issue or will make updates available by mid-1999,
or relatively low cost alternative solutions may be available. However, there
can be no assurance that any such updates will be completed on a timely
basis, if at all, or at a reasonable cost, or that such updates will work as
anticipated in the year 2000.

The Company relies on third party suppliers for the management and
control of fabrication, assembly and testing of substantially all of the
Company's products. The Company is currently in the process of making
inquiries of all of its significant vendors and service providers upon which
it relies. Such evaluation is expected to be completed by June 30, 1999 and
the Company intends to establish contingency plans to provide for alternative
sources as necessary.

The Company has not incurred substantial costs to date to address the
Year 2000 issue and is unable to estimate the additional cost, if any, that
may arise from actions taken by the Company, if any, to address the Year 2000
issue or from the interaction of the Company's products with other companies'
networking devices and systems. In addition, the Company is unable to assess
the potential risks and exposures associated with changes in generally
accepted definitions of Year 2000 compliance that may impact the compliance
of its products. Any failure by the Company to make its products Year 2000
compliant could result in a decrease in sales of the Company's products,
diversion of development resources, damage to the Company's reputation,
increased service and warranty costs and/or possible claims against the
Company by customers as a result of Year 2000 problems caused by the
Company's products, any of which could have a material adverse effect on the
Company, its business, operating results and financial condition.


27



Many of the Company's customers and prospective customers are expected
to devote a substantial portion of their information systems budgets to the
Year 2000 problem over the next several years, and, as a result, spending may
be diverted from wide area networking solutions. In addition, the Company's
customers, which consists primarily of large enterprises operating business
critical applications over the wide area networks that are supported by the
Company's products, may be less willing to purchase wide area networking
products or otherwise implement new network solutions during the second half
of 1999 in anticipation of the Year 2000. The Company relies on a large
variety of business enterprises such as customers, suppliers, creditors,
financial organizations, and domestic and international governmental
entities, for the accurate exchange of data. Any disruption in the computer
systems of any of these third parties could materially and adversely affect
the Company. Due to the Company's focus on the wide area networking market,
which is vulnerable to technological issues involving the Year 2000,
substantially all of the Company's revenues may be at risk. Despite the
Company's efforts to address the Year 2000 impact on its products, internal
systems and business operations, the Year 2000 issue 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, 1998, the Company's principal sources of liquidity
consisted of $14.1 million of cash and cash equivalents. In March 1999, the
Company received a commitment for a new $3 million secured bank line of
credit which is expected to expire in April 2000. There were no borrowings
outstanding as of December 31, 1998.

During 1998, cash used in operating activities was $6.5 million,
compared to $12.4 million for fiscal 1997. Use of cash during 1998 resulted
primarily from the Company's net loss of $15.4 million partially offset by a
net decrease in operating assets and liabilities of $6.5 million. These
changes reflected the higher operating loss, higher levels of payables and
decreased levels of receivables and inventory. Capital expenditures during
fiscal 1998 were $1.2 million, compared to $1.3 million for 1997. At December
31, 1998, the Company had no material commitments for capital expenditures.

As of December 31, 1998, the Company's net working capital was $14.3
million, of which $14.1 million was invested in cash and cash equivalents,
$2.4 million was invested in accounts receivable, and $6.1 million was
invested in inventory. In December 1998, the Company initiated an expense
reduction program. The Company believes that its available cash and cash
equivalents will be sufficient to meet its working capital requirements at
least through 1999.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

RISKS ASSOCIATED WITH FOREIGN EXCHANGE

In 1998, approximately 6.9% 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


28



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, 1998, investments were as folows ($s in millions):

Short-term debt instruments and money market funds $14.1 2 months 5% $14.1

SYNC RESEARCH, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

COMPANY BACKGROUND

Sync Research, Inc. was incorporated in the State of California on September
8, 1981 and was reincorporated in Delaware on September 12, 1995. Sync
Research, Inc.'s principal activity consists of the development, manufacture
and global sale of network communication software and hardware products.

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 accounts have been eliminated. As described
more fully in Note 2, on August 23, 1996, TyLink Corporation (TyLink) merged
with and into Sync Research, Inc. (Sync) in a transaction (the Merger)
accounted for as a pooling of interests; accordingly, the consolidated
financial statements reflect the combined financial position and results of
operations of Sync and TyLink for all periods presented.

ACCOUNTING PERIODS

TyLink's results of operations and cash flows for its fiscal year ended
March 29, 1996 have been combined in the accompanying consolidated financial
statements for the year ended December 31, 1995. Accordingly, TyLink's
results of operations and cash flows for the three months ended March 29,
1996 have been included in the consolidated financial statements in both the
years ended December 31, 1995 and 1996. During the three months ended March
29, 1996, TyLink's revenues, net loss and cash flows were $3,075,000,
$713,000 and $50,000, respectively. The duplicative effect of such loss and
cash activity has been reflected as an adjustment to retained earnings and
cash flows in the consolidated financial statements during the year ended
December 31, 1996.

RECLASSIFICATIONS

Certain prior year amounts have been reclassified to conform with the
current year presentation.

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 accompanying financial
statements. Actual results could differ from those estimates.

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 three months or less
and money market funds to be cash equivalents.

INVENTORIES

Inventories, consisting primarily of computer hardware and components,
are stated at the lower of cost (first-in, first-out basis) or market as
follows (in thousands):

DECEMBER 31,
---------------------
1998 1997

Raw materials ...................... $2,983 $3,636
Work in process .................... 752 862
Finished goods ..................... 2,376 2,873
------ ------

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

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.

In October 1997, the AICPA issued Statement of Position (SOP) No. 97-2,
SOFTWARE REVENUE RECOGNITION, which changed the requirements for revenue
recognition effective for transactions beginning January 1, 1998. The
implementation of the SOP did not have a material impact on the Company's
financial statements.

CAPITALIZED SOFTWARE

Statement of Financial Accounting Standards No. 86, ACCOUNTING FOR THE
COSTS OF COMPUTER SOFTWARE TO BE SOLD, LEASED OR OTHERWISE MARKETED, requires
capitalization of certain software development costs subsequent to the
establishment of technological feasibility. 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. 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. As of December 31,
1998, $455,000 of purchased software has been capitalized as software in
computers, software and equipment. There was no accumulated amortization as
of December 31, 1998 as the related product was not released.

FURNITURE, FIXTURES AND EQUIPMENT

Depreciation and amortization are provided on the straight-line method
over the following estimated useful lives:



Equipment acquired under capitalized leases Term of lease (ranging from 3 to 5 years)

Furniture and fixtures 5 to 7 years
Computers, software and equipment 3 to 7 years
Leasehold improvements Term of lease


LONG-LIVED ASSETS

In accordance with Statement of Financial Accounting Standards No. 121,
ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS
TO BE DISPOSED OF (SFAS No. 121), the Company records impairment losses on
long-lived assets used in operations when events and circumstances indicate
that the assets might be impaired and the undiscounted cash flows estimated
to be generated by those assets are less than the carrying amounts of those
assets.


36



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

Costs related to after-sale service and repair are accrued as warranty
expense in the year of sale and are included in accrued liabilities.

INCOME TAXES

Deferred taxes are provided for items recognized in different periods
for financial and tax reporting purposes in accordance with Statement of
Financial Accounting Standards No. 109, ACCOUNTING FOR INCOME TAXES.

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 and write-offs of assets no longer in use due to the reduction
efforts. The non-recurring charges taken in 1998 and 1997 were as follows (in
thousands):



ACCRUAL ACCRUAL
DESCRIPTION AT 12/31/97 CHARGE ACTIVITY AT 12/31/98
----------- ----------- ------ -------- -----------

Severance and related expenses ..... $354 $1,210 $ (710) $ 854
Idle and excess facility charges
and write-off of assets........ 9 1,547 (446) 1,110
Other non-recurring charges ........ 9 95 (92) 12
---- ------ ------- ------
Total .............................. $372 $2,852 $(1,248) $1,976
---- ------ ------- ------
---- ------ ------- ------


In 1998, the Company completed its 1997 expense reduction program
activities. The Company expects all 1998 expense reduction program activities
will be substantially completed during fiscal 1999. The Company will continue
to evaluate and may adjust its organization and cost structure.

STOCK BASED COMPENSATION

The Company has elected to follow Accounting Principles Board Opinion
No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES and related Interpretations
in accounting for its employee stock options.

PER SHARE INFORMATION


37



Net loss per common share is computed in accordance with Financial
Accounting Standards Board Statement No. 128, EARNINGS PER SHARE, using the
weighted average number of common shares and common share equivalents
outstanding during the periods presented. Common share equivalents result
from the dilutive effect, if any, of outstanding options and warrants to
purchase common stock. The weighted average number of common shares
outstanding for all periods also reflects the issuance of .157 shares of the
Company's common stock for each share of TyLink Series A preferred stock and
common stock. Net loss per share reflects the accretion of dividends and
liquidation value related to TyLink mandatorily redeemable preferred stock.
Such accretion aggregated $486,000 in 1996. The following table sets forth
the computation of basic and diluted net loss per share (in thousands):

NEW ACCOUNTING PRONOUNCEMENTS

Effective for the year ended December 31, 1998, the Company implemented
Financial Accounting Standards Board Statement of Financial Accounting
Standards No. 130, REPORTING COMPREHENSIVE INCOME (Statement No. 130), which
establishes standards for reporting and displaying comprehensive income and
its components with the same prominence as other financial statement
information. The implementation of this standard did not have a material
effect on the Company's consolidated financial statements.

Effective for the year ended December 31, 1998, the Company implemented
Financial Accounting Standards Board Statement of Financial Accounting
Standards No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED
INFORMATION (Statement No. 131), which establishes standards for the way that
public business enterprises report information about operating segments in
annual financial statements and requires that those enterprises report
selected information about operating segments in interim financial reports.
It also establishes standards for related disclosures about products and
services, geographic areas, and major customers. The Company operates in one
business segment. Accordingly, the adoption of Statement No. 131 did not have
a material effect on the Company's consolidated financial statements.

2. MERGER

On August 23, 1996, Sync, SR Acquisition Corp, a wholly-owned subsidiary
of Sync and TyLink Corporation entered into an Agreement and Plan of
Reorganization (the Agreement). Pursuant to the Agreement all outstanding
shares of TyLink's Series A redeemable preferred stock and common stock were
exchanged for 2,148,168 shares of Sync common stock and Sync assumed options
outstanding under a TyLink plan aggregating 423,155 shares of Sync common
stock. In addition, Sync purchased all of the


38




outstanding TyLink Series B mandatorily redeemable preferred stock for $4
million cash plus a sufficient number of shares of Sync common stock that
together have aggregate value equal to the liquidation value of the TyLink
Series B mandatorily redeemable preferred stock.

The Merger has been accounted for under the pooling-of-interests method
of accounting. Accordingly, the historical financial statements for periods
prior to the consummation of the combination have been restated as though the
companies had been combined.

4. 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 competitors could have a substantial impact on the future
operations of the Company.

A substantial portion of the Company's sales are concentrated with a few
communications, networking, and telecommunications companies and large
enterprise end-user organizations. The Company is dependent upon certain
suppliers of key components and contract manufacturers. Sales to two
customers represented 18.5% and 14.1% of the Company's total sales in 1998.
Sales to one customer represented 16.5% and 19% of total sales in 1997 and
1996, respectively

Accounts receivable represent the Company's only significant financial
instrument with potential credit risk. The Company makes periodic evaluations
of the credit worthiness of its customers and generally does not require
collateral. To date, the Company has not experienced any material write-offs
or collection problems. At December 31, 1998, 15 major customers represented
68.8% of total accounts receivable.

Sales to foreign customers, primarily in Europe and the Pacific Rim,
aggregated $1.7 million or 6.9% and $4.5 million or 19.1%, and $4.6 million
or 12.7%, of net sales in 1998, 1997 and 1996, respectively.

The Company has approximately $50 million of federal net operating loss
carryforwards, including acquired net operating losses of Tylink Corporation,
at December 31, 1998, 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):

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.

6. 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, 1998,
1997 and 1996, matching contributions made and expensed by the Company
aggregated $149,000, $164,000 and $57,000, respectively.

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 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 7,741,003 and
2,191,854 shares, respectively, at December 31, 1998.


41



The Company has elected to follow 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. FASB Statement No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION, requires pro forma information regarding net income (loss) and
net earnings (loss) per share using compensation that would have been
incurred if the Company had accounted for its employee stock options under
the fair value method of that Statement. The fair value of options granted
after the initial public offering have been estimated at the date of grant
using a Black-Scholes option pricing model using the following assumptions:



1998 1997 1996
------- ------- -------

Risk free interest rate ................... 6.0% 6.0% 6.5%
Stock volatility factor ................... 1.14 1.30 1.00
Weighted average expected option life ..... 6 years 6 years 6 years
Expected dividend yield ................... 0% 0% 0%


For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The
Company's compensation expense used in determining the pro forma information
may not be indicative of such expense in future periods as the amounts are
only based upon the grants subsequent to 1994. Pro forma information is as
follows (in thousands, except for per share information):



1998 1997 1996
-------- -------- --------

Pro forma net loss ............. $(20,391) $(21,505) $(16,814)
Pro forma net loss per share ... $ (1.17) $ (1.25) $ (1.03)


A summary of the Company's stock option activity, and related

In April 1997 substantially all of the Company's outstanding options
were canceled and repriced with new options having an exercise price of $3.94
per share, the fair market value as of the date of the repricing. The vesting
of the repriced options was suspended for a period of six months from the
date of the repricing. A total of 2,056,460 shares were repriced.

In October 1998, a majority of the Company's outstanding options were
canceled and repriced with new options having an exercise price of $1.13 per
share, the fair market value as of the date of the repricing.


42



The exerciseability of the repriced options was suspended for a period of six
months from the date of the repricing. A total of 2,090,575 shares were
repriced.

The weighted average remaining contractual life of options as of December
31, 1998 were as follows:

Greater than $5.00 ........ 39,000 7.27 18.10 27,687 18.09


The Company has recorded deferred compensation expense of $644,000 for
the difference between the option exercise price or restricted stock purchase
price and the deemed fair value of the Company's common stock for options
granted and restricted stock sold in 1995. This amount is being amortized
over the vesting period of the individual options, generally four years.
Deferred compensation expense recognized in 1998, 1997 and 1996 totaled
$27,000, $79,000 and $265,000, respectively.

In August 1995, the Company's Board of Directors approved the Company's
1995 Employee Stock Purchase Plan (the Purchase Plan), under which 200,000
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 will be equal to 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. During 1998 and 1997, approximately
54,000 and 41,000 common shares, respectively, were purchased under the
Purchase Plan.

7. COMMITMENTS AND CONTINGENCIES

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 District of California, Southern Division. 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 February 16, 1999, the U.S. District
Court issued an order granting Sync's motion to dismiss the first amended
complaint. The plaintiffs have subsequently filed a second amended complaint.
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, 1998.

The Company leases its office facilities and certain equipment under
noncancelable operating leases expiring through 2003. The Company also has
various leased equipment under capital leases that are included in furniture,
fixtures and equipment in the accompanying balance sheets. The accumulated
depreciation and amortization of these leased assets was $192,000 and
$121,000 at December 31, 1998 and 1997, respectively. Depreciation and
amortization of leased equipment under capital leases are included in
depreciation expense.

Rent expense for 1998, 1997 and 1996 was $634,000, $744,000 and
$659,000, respectively.

In connection with certain agreements with several of its customers, the
Company has indemnified these customers against losses arising from specific
events, including product/service performance failures and third-party
intellectual property rights. Management believes that any costs incurred
under these indemnification arrangements will not have a material adverse
impact on the Company's financial position or results of operations.

8. MANDATORILY REDEEMABLE SERIES B PREFERRED STOCK

On January 23, 1995, TyLink issued 2,540,820 shares of Mandatorily
Redeemable Series B Preferred Stock for proceeds of $1.49135 per share. In
connection with the financing, TyLink also issued 400,366 shares of common
stock for proceeds of $2.40 per share. In connection with the Merger, the
Company purchased all of the outstanding mandatorily redeemable preferred
stock for $4 million cash and 208,677 shares of common stock.

9. CREDIT AGREEMENT

In March 1999, the Company received a commitment for a new $3,000,000
credit agreement with a bank. Outstanding borrowings under this credit
agreement will be secured by substantially all of the Company's assets and
are subject to an interest rate equal to the Bank's prime rate plus one half
percent on amounts outstanding. The agreement is expected to expire in April
2000. There were no borrowings outstanding as of December 31, 1998.
