                                       PART I

ITEM 1.  BUSINESS.

GENERAL

     ODS Networks, Inc. ("ODS", the "Company" or the "Registrant") develops,
manufactures, markets and supports switches, intelligent hubs, sophisticated
management and security software and related computer networking and
internetworking products for application in local area networks ("LANs"). The
Company's products are designed to support the four major industry standards
currently applicable in the LAN industry: Ethernet, Token Ring, Fiber
Distributed Data Interface ("FDDI") and Asynchronous Transfer Mode ("ATM").
These products allow customers to integrate a wide variety of computer equipment
in numerous flexible configurations into enterprise-wide computer networks.

     The Company's strategy is to provide a wide variety of technologically
advanced LAN products to satisfy an ever expanding range of customer
requirements. To accomplish its objectives, the Company engages in ongoing
efforts to (i) enhance and expand its existing products in response to rapidly
changing customer preferences and evolving industry standards and technologies,
and (ii) develop and introduce, in a timely manner, products which incorporate
new technologies, comply with industry standards and achieve market acceptance.

     The Company markets and distributes its products primarily through a direct
sales force to end-users and by numerous domestic and international system
integrators and value added resellers.  The Company's end-user customers include
manufacturing, telecommunications, retail, transportation, health care,
insurance, entertainment, utilities and energy companies; government agencies;
financial institutions; and academic institutions.

     The Company was organized in Texas in September 1983 and reincorporated in
Delaware in October 1995.  The Company changed its name in April 1997 from
Optical Data Systems, Inc. to ODS Networks, Inc.  The Company's principal
executive offices are located at 1101 E. Arapaho Road, Richardson, Texas 75081,
and its telephone number is (972) 234-6400. 

THE LAN INDUSTRY

     The power of personal computers ("PCs"), workstations and network servers
has increased dramatically during the past decade.  The rapid proliferation of
these devices has created a demand for an effective method to enable users to
communicate with each other to access common databases, software and peripheral
devices.  The LAN industry has evolved to provide a means by which computers and
related devices ("nodes") located within a limited geographical area, such as a
single office building or a campus, can be interconnected by means of a common
cabling system to permit communication and the sharing of data and resources. 
These LANs can then be interconnected into wide area networks ("WANs") that
enable all of the client and server devices in an enterprise to communicate with
each other.

     In the past, LAN technologies such as Ethernet and Token Ring have required
networked devices to take turns communicating on a singe LAN.  Such technologies
are often referred to as shared-media or shared-bandwidth technologies because
they require computers to contend for the total capacity or "bandwidth" of a
LAN.  Until recent years, intelligent shared-media hubs, each of which functions
as a single LAN, interconnected with routers have represented the most widely
used network architecture.  The Company's Infinity intelligent hub product
family, introduced during the fourth quarter of 1992, represents one of the
industry's most reliable, flexible and manageable intelligent hubs.  However,
the performance of these shared-bandwidth LANs has declined in recent years due
to the increased processor speeds of computers, increased size of LANs and
higher bandwidth requirements of software applications such as document image
processing, medical imaging, video and the World Wide Web.

     In recent years, a new generation of LAN technology has emerged utilizing
"switching" to relieve the performance issues experienced in shared-bandwidth
LANs.  Some switches have been designed to enhance the performance of existing
shared-bandwidth LANs by reducing the number of devices taking 


                                         2

<PAGE>

turns and sharing the capacity of a single LAN Ethernet segment or token ring. 
More recently, switches such as the Company's InfiniteSwitch and LANBlazer
product lines have been designed to replace the traditional hub and router
architecture.  In a totally switched network, each PC, workstation and server
has its own dedicated network connection; thus, networked devices do not
experience the performance constraints of taking turns transmitting information
over the LAN. 

     The migration of data from tightly controlled mainframe computers onto
LANs, workstations and PCs and connectivity of an organization's network to the
Internet have created security issues.  In the past, an organization could rely
on tight mainframe access controls to restrict access to sensitive data. 
However, many networks now contain proprietary, intellectual property and other
sensitive data being carried by insecure network protocols.  Today, firewalls
represent the most common form of network security, forming barriers to entry
into an organization's network.  However, the hacker community has developed
innovative techniques for circumventing firewalls.  Furthermore, firewalls do
not adequately address the security issues related to disgruntled employees or
those who would commit corporate espionage.  Thus, a need has evolved in the
industry for the implementation of comprehensive monitoring of installed
networks and real-time response to security violations.  Recently, products such
as the Company's SecureDetector and SecureSwitch have been designed to improve
data security by implementing real-time network intrusion detection and response
technology.

THE ODS STRATEGY

     The Company's strategy is to provide a wide variety of technologically
advanced LAN products to satisfy evolving customer requirements.  Currently, the
Company's objective is to be a market leader in the migration of LAN technology
to switched, dedicated bandwidth connections by offering a family of LAN
switching products that lead the industry in price/performance, features,
flexibility, reliability, management, security and investment protection.  The
key elements of the Company's strategy are outlined below.

     LAN MARKET LEADERSHIP.  The Company has focused on the high end of the LAN
market.  The Company believes that high-end customers tend to be early adopters
of new technology. The Company works closely with selected large end users to
identify market needs and define product specifications early in the development
process. This approach results in a thorough understanding of end-user
requirements prior to commencement of the design process.  The Company believes
that its InfiniteSwitch and LANBlazer product lines meet the high-end LAN market
requirements to provide switched, dedicated bandwidth, high-speed connections in
modular, flexible and reliable chassis systems with competitive pricing.

     NETWORK MANAGEMENT AND SECURITY.  As LANs become more diverse and complex
and provide increased bandwidth capacity, organizations require more
sophisticated network management systems. The Company has developed advanced
network management systems to allow network administrators to monitor and
control all of the physical layer components of a network, including third-party
products.  Further, security issues created by unauthorized access to sensitive
data within an organization's intranet by employees, or by competitors, thieves
and vandals through the Internet, have created the need for additional network
security capabilities.  By working closely with selected large organizations
with stringent requirements for network security, the Company gains a thorough
understanding of security requirements and develops products to address those
requirements.  The Company intends to continue to differentiate itself from its
competitors by enhancing its current advanced network management and security
systems and developing new technology to meet evolving end-user specifications. 

     INDUSTRY STANDARDS.   A LAN is based on "protocols" or rules that govern
access to and communication over the network. To facilitate communication with
each other, connected nodes must obey protocols to access the network and
communicate with other nodes.  The Company's diverse product lines include
products compliant with Ethernet, Token Ring, FDDI, ATM and other industry
standards.  The Company intends to continue its strategy of compliance with
industry standards rather than develop proprietary networking solutions.  The
Company's research and development efforts are, in significant part, devoted to
the continued introduction and development of new products and enhancement of
existing products based on existing as well as emerging industry standards. 


                                         3

     SALES, MARKETING AND SUPPORT.  The Company plans to increase its sales in
North America by expanding its direct sales and marketing programs and by
expanding the number of system integrators, original equipment manufacturers,
and value added resellers supported by the Company's direct sales force. 
Internationally, the Company intends to expand the number of  third-party
resellers supported by the Company's direct sales force.  The Company's sales
force and its field sales engineers are knowledgeable in a wide variety of
hardware and software networking environments and provide valuable consulting
services to ODS customers and partners.  ODS intends to continue to assist its
partners and end-user customers to design LAN solutions, develop a migration
path to implement advanced LAN solutions while leveraging a customer's existing
investment and provide numerous other valuable technical services for LAN
applications. 

ODS PRODUCTS

     NETWORK MANAGEMENT.  As networks evolve from shared media to purely
switched architectures, network management requirements are also evolving beyond
the traditional device-oriented management tools.  The ODS InfiniteView suite of
network management software applications provides a robust platform for
proactively managing a complex, switched-only environment.  The InfiniteView
family includes the following network management products:  Domain Director,
Health Monitor, Switch Manager and ProtoCop.  The InfiniteView family is a set
of modular, yet interoperable, products which provide a powerful view and
management capability supporting fault monitoring, security monitoring,
performance measurements, accounting and configuration management.

     The InfiniteView Domain Director is a network management application which
simplifies a network manager's job of maintaining the network by discovering all
manageable devices in the network and creating logical groupings of those
devices.  Customized graphical user interfaces ("GUIs") are provided by the
Domain Director along with real-time status of each network device.

     The InfiniteView Health Monitor is a network management application that
monitors segments, rings and switches in a network and efficiently isolates
problems down to a specific address and port to allow a user to evaluate the
health of the network.  Health Monitor uses a drill down technique to quickly
and effectively isolate problems and minimizes the time reviewing screens and
tables.

     The InfiniteView Switch Manager is the primary mechanism for managing and
controlling configurations of the switches in a network.  The Switch Manager
features a customized GUI to provide simple point and click management and
control of LAN switches and other networking components.  Switch Manager allows
the user to configure all aspects of the switch, including enabling and
disabling ports, setting up security for the switch, real-time monitoring of the
state of all switch interfaces and presenting a unified view of all agents in a
chassis.

     The InfiniteView ProtoCop is a unique network investigative tool which
offers a proactive model for analyzing, filtering and viewing network management
data.  With ProtoCop, network managers can better plan and secure their network
from outside invaders, internal configuration and performance problems and track
against performance-based service level agreements.

     NETWORK SECURITY.  In addition to the security features of the InfiniteView
ProtoCop network management software application, the ODS SecureDetector and
SecureSwitch products are designed to improve network security by implementing
comprehensive network monitoring, intrusion detection and response technologies.
The SecureDetector can be connected simultaneously to multiple Ethernet segments
to passively monitor and audit data traversing the network, and can identify
network conversations that fit known attack profiles and enable tracking,
logging and termination of unauthorized network conversations.  The SecureSwitch
combines the security capabilities of the SecureDetector into a wire-speed,
high-performance, modular switching implementation.  Consistent with ODS'
strategy to provide a high level of investment protection to its customers, the
installed base of ODS InfiniteSwitches can be upgraded to fully support the
SecureSwitch capabilities.

     INFINITESWITCH.  The expansion of bandwidth intensive operating systems and
applications, coupled with rapid advancement in client/server computing, is
driving the transition from shared-bandwidth architectures to switched
architectures.  Switched architectures, which began as high-speed switching in
the network backbone, are now extending to users' desktops to maximize network
performance and the productivity of each individual user.  The ODS
InfiniteSwitch product family, introduced in 1996, comprises flexible,
competitively priced, switched connectivity while providing scaleable,
high-speed ATM, FDDI and Fast Ethernet uplinks that fully integrate each LAN
device into more complex, enterprise networks.  
     
     The ODS InfiniteSwitch product family includes modular chassis, switch and
uplink modules, and network management software.  The modular chassis are
available with 12, 7, 4 and 2 slots.  Each switch, uplink and management module
is re-deployable across these modular chassis platforms, including the Company's
prior generation Infinity intelligent hub chassis, thereby reducing the
operating costs associated with spare units and enabling a cost-effective
migration from shared-bandwidth network architectures and small work groups to
large switched networks.

     The ODS InfiniteSwitch product family offers numerous configurations of
dedicated 10 megabit per second ("Mbps") Ethernet and 100 Mbps Fast Ethernet
connections to every device in a network using unshielded twisted pair cabling
or fiber optic transmission media.  The InfiniteSwitch utilizes a single 1.28
Gbps backplane with a dual bus architecture.  Each bus is independent of the
other, providing both load balancing capabilities and a high degree of fault
tolerance.  By separating the management function from the switching operation
and providing distributed memory architecture, fault tolerance is enhanced. 
Additionally, every ODS InfiniteSwitch module can operate in stand-alone mode
over its own 640 Mbps of bandwidth.  The dual bus architecture, number of
possible Ethernet and Fast Ethernet module configurations, modular stand-alone
mode capabilities and range of uplink options enable flexible network
configurations by network administrators using the ODS InfiniteView network
management system.
     
     LANBLAZER.  For very high bandwidth server farms, corporate backbone
switching and high-end applications at the individual user level, ODS introduced
the LANBlazer 7000 Gigabit Ethernet switch in January 1998.  The LANBlazer 7000
includes a modular 7-slot chassis that supports over 45 Gbps of bandwidth and
connects up to 24 separate Gigabit Ethernet ports or up to 120 Fast Ethernet
ports.  One implementation of the LANBlazer 7000 is as a backbone network for
users of ODS' InfiniteSwitches, high- density Ethernet switches.  Additional
features of the LANBlazer include high-speed Layer 3 switching, VLAN management
and flexible network management capabilities.
     
     TURBOACCESS SWITCHES.  The TurboAccess family of workgroup switches and
managed workgroup switches allow workgroups to migrate from conventional 10 Mbps
shared Ethernet domains to multiple dedicated switched Ethernet segments.  These
switches deliver dedicated 10 Mbps links to each attached LAN segment or
attached workstation with no need to upgrade existing cabling, hubs or network
adapters.  The TurboAccess switches include optional Fast Ethernet uplinks,
allowing a migration to higher speed networks while preserving a customer's
existing investment in network infrastructure. 
     
     INFINITY INTELLIGENT HUBS.  The ODS Infinity intelligent hub product
family, introduced in 1992, was designed to be used in large or multi-story
buildings and campus settings.  The ODS Infinity series has a flexible backplane
that supports Ethernet, Token Ring, ATM and FDDI modules in a single chassis
platform and features a large number of modules and options designed to create
highly manageable and reliable network architectures.  Each intelligent hub
ranges in size from 4 to 12 modular slots and supports up to 528 Ethernet ports
with up to 44 separate Ethernet segments or up to 352 Token Ring ports with up
to 44 managed Token Rings.  The Company's ATM and FDDI products are used by
customers in several applications such as metropolitan area networks ("MANs"),
campus backbones, interconnections for high performance workstations and file
servers, and direct connections between host computers.  Certain third-party
products, such as segment switching and router modules, can also be integrated
in Infinity intelligent hubs. 

     MICRO-INFINITY.  The ODS Micro-Infinity product family features a
micro-modular design for growing businesses, remote branch offices and work
groups within organizations.  This product family supports Ethernet, Token Ring,
ATM and FDDI modules, third-party segment switching and remote access router
modules.  


                                         5

<PAGE>

     NANO HUB.  The ODS Nano Hub product line features a managed, fixed-port
configuration with 12 to 24 ports of shared Ethernet connections.  The Nano Hub
is available with integrated Frame Relay Access Device ("FRAD") or Integrated
Service Digital Network ("ISDN") to provide reliable LAN connectivity with
remote access for branches and remote offices.

     THIRD-PARTY PRODUCTS.  The Company believes that it is beneficial to work
with third parties with complementary technologies to broaden the appeal of the
Company's switches and intelligent hub products.  These alliances allow ODS to
provide integrated solutions to its customers, combining ODS developed
technology with third-party products such as certain routers from Cisco Systems,
Inc., ATM switches from FORE Systems, Inc. and Gigabit Ethernet switch
technology from Lucent Technologies.  As the Company also competes with these
technology partners in certain segments of the market, there can be no assurance
that the Company will have access to all of the third-party products which may
be desirable in order to offer fully integrated solutions to ODS customers.  

     CUSTOMER SERVICES.  In addition to manufacturing broad lines of LAN
products, the Company also offers a wide range of services for LANs, including
consulting, design and configuration, project planning and management,
performance analysis and installation and maintenance.

PRODUCT DEVELOPMENT

     The LAN industry is characterized by rapidly changing technology, standards
and customer demands. Management believes that the Company's future success
depends in large part upon the timely enhancement of existing products as well
as the development of technologically advanced new products which meet industry
standards, perform successfully and achieve market acceptance. The Company is
currently developing and marketing next-generation LAN switching products that
will support data applications, video and audio applications as well as intranet
and Internet applications. The Company is also investing in the development of
products which comply with emerging industry standards and is continuously
engaged in testing to ensure that the Company's products interoperate with other
manufacturers' products which comply with industry standards.  However, there
can be no assurance that the Company will be successful in enhancing its
existing products or in selecting, developing, manufacturing and marketing new
products which will perform satisfactorily and achieve market acceptance.  Nor
can there be any assurance that the Company will be able to respond effectively
to technological changes or new product announcements by competitors, which
could render portions of the Company's inventory obsolete.

     During 1997, 1996 and 1995, the Company's research and development
expenditures were $10.8 million, $10.4 million and $8.0 million, respectively.
All of the Company's expenditures for hardware and software research and
development costs have been expensed as incurred. At December 31, 1997, the
Company had 63 employees engaged in research and product development.  The
Company intends to continue to increase its research and development staff and
expenditures.

MANUFACTURING AND SUPPLIERS

     The Company's manufacturing operations consist primarily of final assembly,
testing and quality control of subassemblies and finished units.  Materials used
by the Company in its manufacturing processes include semiconductors such as
microprocessors, memory chips and application specific integrated circuits
("ASICs"), printed circuit boards, power supplies and enclosures.  All of the
materials used in the Company's products are purchased under contracts or
purchase orders with third parties.  While the Company believes that many of the
materials used in the production of its products are generally readily available
from a variety of sources, certain key components such as microprocessors and
ASICs are available from one or a limited number of suppliers.  For example,
certain ASICs designed into the Company's InfiniteSwitch products are supplied
by FORE Systems (see "Competition").  The lead times for delivery of components
vary significantly and exceed twelve weeks for certain components.  If the
Company should fail to forecast its requirements accurately for components, it
may experience excess inventory or shortages of certain components which could
have an adverse effect on the Company's business and operating results. 
Further, any interruption in the supply of any of these components, or the 


                                         6

<PAGE>

inability of the Company to procure these components from alternative sources at
acceptable prices within a reasonable time, could have an adverse effect on the
Company's business and operating results.

     The Company's operational strategy relies on outsourcing of printed circuit
board assembly and certain other operations to reduce fixed costs and to provide
flexibility in meeting market demand.  The Company inserts the printed circuit
board-based modules, assembled by a variety of domestic third-party contract
assembly companies, into product enclosures in combination with power supplies,
ODS software and other components to configure systems to meet the needs of
end-user customers.  There can be no assurance that the Company will effectively
manage its third-party contractors or that these contractors will meet the
Company's future requirements for timely delivery of products of sufficient
quality and quantity.  Further, the Company intends to introduce a number of new
products and product enhancements in 1998 which will require that the Company
rapidly achieve volume production of those new products by coordinating its
efforts with those of its suppliers and contractors.  The inability of the
third-party contractors to provide ODS with adequate supplies of high-quality
products could cause a delay in the Company's ability to fulfill orders and
could have an adverse effect on the Company's business and operating results.

INTELLECTUAL PROPERTY AND LICENSES

     The Company's success and its ability to compete is dependent, in part,
upon its proprietary technology.  The Company does not hold any issued 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. 
The Company has also entered into confidentiality agreements with its employees
and enters into non-disclosure agreements with its suppliers, resellers and
certain customers to limit access to and disclosure of proprietary information. 
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.

     There are many patents held by companies which relate to the design and
manufacture of networking systems.  Potential claims of infringement could be
asserted by the holders of those patents.  The Company could incur substantial
costs in defending itself and its customers against any such claim regardless of
the merits of such claims.  In the event of a successful claim of infringement,
the Company may be required to obtain one or more licenses from third parties. 
There can be no assurance that the Company could obtain the necessary licenses
on reasonable terms.

     The Company has entered into several  software and product license
agreements. These license agreements provide the Company with additional
software and hardware components that add value to its intelligent hub, switch
and management products. These license agreements do not provide proprietary
rights which are unique or exclusive to the Company and are generally available 
to other parties on the same or similar terms and conditions, subject to payment
of applicable license fees and royalties.

SALES, MARKETING AND CUSTOMERS

     The Company markets and distributes its products primarily through a direct
sales force to end users and through numerous domestic and international system
integrators and value added resellers.  The Company's direct sales and marketing
organization currently consists of 143 individuals, including managers, sales
representatives, marketing personnel and technical support personnel.  

     FIELD SALES FORCE.  The Company's direct sales organization focuses on
major account sales, promotes the Company's products to current and potential
customers, and monitors evolving customer requirements.  The field sales and
technical support force provides training and technical support to the Company's
resellers and end users and assists ODS customers to design LAN solutions and to
develop a migration path to implement advanced LAN solutions while leveraging an
end user's existing investment.

     RESELLERS.  Domestic and international system integrators and value added
resellers (collectively, "resellers") sell ODS products as stand-alone solutions
to end users and integrate ODS products with products sold by other LAN and WAN
vendors into networking systems that are sold to end users.  The Company's field
sales force and technical support organization provide support to these
resellers.  Historically, resellers have sold the Company's products to large
corporations and government agencies.  The Company has initiated a "Partners
Plus" program targeted at resellers who serve medium sized organizations.  The
Company's agreements with resellers are non-exclusive, and the Company's
resellers generally sell other products which may compete with ODS products. 
Resellers may place higher priority on products of other suppliers who are
larger than and have more name recognition than ODS, and there can be no
assurance that resellers will  continue to sell and support the Company's
products.

     FOREIGN SALES.  The Company believes that rapidly evolving international
markets are important sources of future net sales for the Company. The Company's
export sales are currently being made through international resellers in Europe,
Asia, Latin America  and Canada supported by ODS' international sales and
technical support organization.  Export sales accounted for approximately 27.2%,
14.4% and 11.6% of net sales in 1997, 1996 and 1995, respectively.  See
Management's Discussion and Analysis of Financial Condition and Results of
Operations incorporated by reference and included in this report for a
geographic breakdown of the Company's product revenue from sales to customers
outside the United States for the years ended December 31, 1997, 1996 and 1995. 
Sales to foreign customers and resellers generally have been made in United
States dollars.  The Company's international operations may be affected by
changes in demand resulting from fluctuations in currency exchange rates and
local purchasing practices, including seasonal fluctuations in demand, as well
as by risks such as increases in duty rates, difficulties in distribution,
regulatory approvals and other constraints upon international trade.  For
example, the fluctuations in currency exchange rates and adverse economic
developments in Malaysia, South Korea and certain other countries adversely
affected demand for the Company's products in those countries in the fourth
quarter of 1997 and may continue to adversely affect demand for the Company's
products in those countries in 1998.

     MARKETING.  The Company has implemented several methods to market its
products, including regular participation in trade shows and seminars,
advertisement in trade journals, telemarketing, distribution of sales literature
and product specifications and ongoing communications with its resellers and
installed base of end-user customers.

     CUSTOMERS.  The Company's end-user customers include manufacturing,
telecommunications, retail, transportation, health care, entertainment,
insurance, utilities and energy companies; government agencies; financial
institutions; and academic institutions.  Sales to certain customers and groups
of customers can be impacted by seasonal capital expenditure approval cycles,
and sales to customers within certain geographic regions can be subject to
seasonal fluctuations in demand.

     Although the Company sells its products to many customers, direct sales to
three such resellers and end-user customers, Electronic Data Systems Corporation
("EDS"), AT&T Corp. ("AT&T") and various agencies of the U. S. Government
(aggregated as one), have each accounted for 10% or more of the Company's net
sales in at least one of the past three fiscal years as indicated in the
following schedule.

- --------------------------------------------------------------------------------
</TABLE>

     A large portion of the products sold to EDS during the periods shown were
integrated with other products or services and sold to end users by EDS.  A
large portion of sales to AT&T in 1995 were attributable to a major U.S. Army
customer of AT&T.  No other customer accounted for as much as 10% of the
Company's net sales in 1997, 1996 or 1995, respectively.  The loss of any of
these customers could have a material adverse effect on the Company and its
operating results if not replaced.

     Most of the Company's business with the U.S. Government is on a fixed-price
basis. Government contracts customarily include provisions which provide for
cancellation at the convenience of the Government.  In addition, upon
cancellation by the Government, the Company generally would be entitled to
reimbursement of costs incurred, plus a pro rata share of profit. The Company
has never received a cancellation of a material government contract and has no
reason to anticipate any such cancellation. The products sold, characteristics
and business risks associated with the Company's sales to U.S. Government
agencies do not differ materially from those associated with sales of the
Company's products to commercial customers.

     BACKLOG.  The Company believes that only a small portion of its order
backlog is noncancelable and that the dollar amount associated with the
noncancelable portion is immaterial.  The Company manufactures its products
based upon its forecast of customers' demand and maintains inventories of
sub-assemblies and finished products in advance of receiving firm orders from
customers.  Orders are generally fulfilled by the Company within one to four
weeks following receipt of an order.  Because of the generally short cycle
between order and shipment and occasional customer-initiated changes in delivery
schedules or cancellation of orders which are made without significant penalty,
the Company does not believe that its backlog as of any particular date is
indicative of future net sales.  

     CUSTOMER SUPPORT, SERVICE AND WARRANTY.  The Company services, repairs and
provides technical support for its products. The ODS field sales and technical
support force work closely with resellers and end-user customers on-site and by
telephone to assist with pre- and post-sales support services such as network
design, system installation and technical consulting. By working closely with
the Company's customers, ODS employees gain a thorough understanding of end-user
requirements and provide input to the product development process.

     The Company warrants all its products against defects in materials and
workmanship for periods ranging from 90 days to 12 months. Before and after
expiration of the product warranty period, the Company offers both on-site and
factory-based support, parts replacement and repair services. Extended warranty
services are separately invoiced on a time and materials basis or on an annual
maintenance contract. 

COMPETITION

     The market for network intelligent hubs and switches is intensely
competitive and subject to frequent product introductions with improved
price/performance characteristics.  Networking suppliers compete in areas such
as conformity to existing and emerging industry standards, interoperability with
other networking products, network management capabilities, performance, price,
ease of use, scalability, reliability, flexibility, product features and
technical support.  The Company believes that its solutions-oriented approach to
networking (combining network design services, ODS products and third-party 


                                         9

<PAGE>

products to provide superior networking systems to customers) provides the
Company a competitive advantage with large organizations with complex networking
requirements.
     
     There are numerous companies competing in various segments of the
intelligent hub and switch markets.  The Company's principal competitors include
Cisco Systems, Inc., Cabletron Systems, Inc., Bay Networks, Inc., 3Com
Corporation, FORE Systems, Inc., Xylan Corporation and International Business
Machines Corporation.  Several of the Company's competitors have substantially
greater financial, technical, sales and marketing resources, better name
recognition and a larger customer base than the Company.  In addition, many of
the Company's competitors offer customers a broader product line which provides
a more comprehensive networking solution than the Company currently offers.
Certain companies in the networking industry have expanded their product lines
or technologies in recent years as a result of acquisitions.  Further, more
companies have developed products which conform to existing and emerging
industry standards and have sought to compete on the basis of price.  Increased
competition in the networking industry 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 will be able to compete
successfully in the future with current or new competitors.

EMPLOYEES

     As of December 31, 1997, the Company employed a total of 384 persons,
including 143 in sales, marketing and technical support, 160 in manufacturing
and operations, 63 in research and product development, and 18 in administration
and finance. 

     None of the Company's employees are represented by a labor organization,
and the Company is not a party to any collective bargaining agreement. The
Company has not experienced any work stoppages and considers its relations with
its employees to be good.

     Competition in the recruiting of personnel in the computer and
communications industry is intense. The Company believes that its future success
will depend in part on its continued ability to hire, motivate and retain
qualified management, sales and marketing, and technical personnel. To date, the
Company has not experienced significant difficulties in attracting and retaining
qualified employees.

FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS   

     This report may include forward-looking statements that involve risks and
uncertainties.  In addition to those factors discussed elsewhere in this Form
10-K and other filings with the Securities and Exchange Commission, the Company
identifies the following factors which could affect the Company's actual results
and cause actual results to differ materially from those in the forward-looking
statements.

     TECHNOLOGICAL CHANGES.  The market for the Company's products is
characterized by frequent product introductions, rapidly changing technology and
continued evolution of new industry standards. The market for network
intelligent hubs and switches requires the Company's products to be compatible
and interoperable with products and architectures offered by various vendors,
including other networking products, workstation and personal computer
architectures and computer and network operating systems.  The Company's success
will depend to a substantial degree upon its ability to develop and introduce in
a timely manner new products and enhancements to its existing products that meet
changing customer requirements and evolving industry standards.  The development
of 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 and support new or
enhanced products successfully in a timely manner.  Further, the Company or its
competitors may introduce new products or product enhancements that shorten the
life cycle of or obsolete the Company's existing product lines which could have
a material adverse effect on the Company's business, operating results and
financial condition.


                                         10

<PAGE>

     COMPETITION AND MARKET ACCEPTANCE.  The market for network intelligent hubs
and switches is intensely competitive and subject to frequent product
introductions with improved price/performance characteristics.  Even if the
Company does introduce advanced products which meet evolving customer
requirements in a timely manner, there can be no assurance that the new Company
products will gain market acceptance.  Many networking companies, including
Cisco Systems, Inc. ("Cisco"), Cabletron Systems, Inc. ("Cabletron"), Bay
Networks, Inc. ("Bay Networks"), FORE Systems, Inc. ("FORE Systems"), Xylan
Corporation ("Xylan")  and others, have substantially greater financial,
technical, sales and marketing resources, better name recognition and a larger
customer base than the Company.  Many of the Company's large competitors offer
customers a broader product line which provides a more comprehensive networking
solution than the Company currently offers.  The Company anticipates increased
competition from large telecommunication equipment vendors which are expanding
their capabilities in the data networking market.  For example, Lucent
Technologies has acquired several networking companies to enhance its
capabilities in data networking.    Further the Company anticipates increased
competition from private "start-up" companies that have developed or are
developing advanced network switching products.  Increased competition in the
networking industry 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. 

     The Company is pursuing a strategy to increase the percentage of its
revenue generated through indirect sales channels including value added
resellers, system integrators, original equipment manufacturers and network
service providers.  There can be no assurance that the Company's products will
gain market acceptance in these indirect sales channels.  Further, competition
among networking companies to sell products through these indirect sales
channels could result in significant price competition and reduced profit
margins.

     The Company is also pursuing a strategy to broaden and further
differentiate its product line by introducing complementary network switching,
management and security products and incorporating new technologies into its
existing product line.  There can be no assurance that the Company will
successfully introduce these products or that such products will gain market
acceptance.  The Company anticipates competition from networking companies,
network security companies and others in each of its product lines.  The Company
anticipates that profit margins will vary among its product lines and that
product mix fluctuations could have an adverse effect on the Company's overall
profit margins. 

     ACQUISITIONS. Cisco, Cabletron, Bay Networks, FORE Systems, Lucent
Technologies and other competitors have recently acquired several networking
companies with complementary technologies, and the Company anticipates that such
acquisitions will continue in the future. These acquisitions may permit such
competitors to accelerate the development and commercialization of broader
product lines and more comprehensive networking solutions than the Company
currently offers.  In the past, the Company has relied upon a combination of
internal product development and partnerships with other networking vendors to
provide competitive networking solutions to customers.  Certain of the recent
and future acquisitions by the Company's competitors may have the effect of
limiting the Company's access to commercially significant technologies. 
Further, the business combinations and acquisitions in the networking industry
are creating companies with larger market shares, customer bases, sales forces,
product offerings and technology and marketing expertise.  There can be no
assurance that the Company will be able to compete successfully in such an
environment.

     The Company may, in the future, acquire or invest in another company,
business unit, product line, or technology to accelerate the development of
products and sales channels complementary to the Company's existing products and
sales channels.  Acquisitions involve numerous risks, including difficulties in
assimilation of operations,  technologies, and products of the acquired
companies; risks of entering markets in which the Company has no or limited
direct prior experience and where competitors in such markets have stronger
market positions; the potential loss of key employees of the acquired company;
and the diversion of management's attention from normal daily operation of the
Company's business.


                                         11

<PAGE>

     PRODUCT TRANSITIONS.  Once current networking products have been in the
market place for a period of time and begin to be replaced by higher performance
products (whether of the Company's or a competitor's design), the Company
expects the net sales of such networking products to decrease. In order to
achieve revenue growth in the future the Company will be required to design,
develop and successfully commercialize higher performance products in a timely
manner.  For example,  the market for shared bandwidth intelligent hubs, sales
of which represented the  majority of the Company's net sales over the past
several years,  decreased in 1997 and may continue to decrease as switching
products with enhanced price/performance characteristics gain market acceptance.
There can be no assurance that the Company will be able to introduce new
products and gain market acceptance quickly enough to avoid adverse revenue
transition patterns during current or future product transitions.

     MANUFACTURING AND AVAILABILITY OF COMPONENTS.  Factors relating to
Manufacturing and Availability of Components that could affect the Company's
actual results and cause actual results to differ materially from those in
forward-looking statements are discussed in the section above entitled
"Business--Manufacturing and Suppliers".

     THIRD-PARTY PRODUCTS.  The Company believes that it is beneficial to work
with third parties with complementary technologies to broaden the appeal of the
Company's switches, intelligent hub and network security products.  These
alliances allow ODS to provide integrated solutions to its customers, combining
ODS developed technology with third-party products such as certain routers from
Cisco, ATM switches from FORE systems and Gigabit Ethernet switch technology
from Lucent Technologies.  As the Company also competes with these technology
partners in certain segments of the market, there can be no assurance that the
Company will have access to all of the third-party products which may be
desirable in order to offer fully integrated solutions to ODS customers.

     DEPENDENCE ON KEY CUSTOMERS.   A relatively small number of customers have
accounted for a significant portion of the Company's revenue. U.S. Government
agencies and strategic network integrators, such as EDS, which purchase the
Company's products for internal use and offer the Company's products for resale,
are expected to continue to account for a substantial portion of the Company's
net revenue.  The Company continuously faces competition from Cisco, Cabletron,
Bay Networks, FORE Systems, Xylan and others for U.S. Government networking
projects and corporate networking installations.  Any reduction or delay in
sales of the Company's products to these customers could have a material adverse
effect on the Company's operating results.

     INTERNATIONAL OPERATIONS.  Export sales accounted for approximately 27.2%
of the Company's revenue in 1997.  The Company expects that export sales will
represent a significant portion of its business in the future.  The Company's
international operations may be affected by changes in demand resulting from
fluctuations in currency exchange rates and local purchasing practices,
including seasonal fluctuations in demand, as well as by risks such as increases
in duty rates, difficulties in distribution and other constraints upon
international trade.  For example, the fluctuations in currency exchange rates
and adverse economic developments in Malaysia, South Korea and certain other
countries adversely affected demand for the Company's products in those
countries in the fourth quarter of 1997 and may continue to adversely affect
demand for the Company's products in those countries in 1998.  Additionally,
while the Company's current products are designed to meet relevant regulatory
requirements of the foreign markets in which they are sold, any inability to
obtain any required foreign regulatory approvals on a timely basis could have a
material adverse effect on the Company's operating results. 

     INTELLECTUAL PROPERTY.   Factors relating to Intellectual Property that
could affect the Company's actual results and cause actual results to differ
materially from those in forward-looking statements are discussed in the section
above entitled " Business--Intellectual Property and Licenses".

     IMPACT OF YEAR 2000.   Some of the Company's older computer programs were
written using two digits rather than four to define the applicable year.  As a
result, those computer programs have time-sensitive software that recognize a
date using "00" as the year 1900 rather than the year 2000.  This could cause a
system failure or miscalculations causing disruptions of operations, including,
among other things, a temporary inability to process transactions, send
invoices, or engage in similar normal business activities.


                                         12

<PAGE>

     The Company has completed an assessment and will have to modify or replace
portions of its software so that its computer systems will function properly
with respect to dates in the year 2000 and thereafter.  The total Year 2000
project cost is estimated to be immaterial.

     The Company has initiated communications with all of its significant
suppliers and large customers to determine the extent to which the Company's
interface systems are vulnerable to those third parties' failure to remediate
their own Year 2000 Issues.  There can be no guarantee that the systems of other
companies on which the Company's systems rely will be timely converted and would
not have an adverse effect on the Company's systems.  The Company has determined
it has immaterial exposure to contingencies related to the Year 2000 Issue for
the products it has sold.  

     The Year 2000 project is estimated to be completed not later than December
31, 1998, which is prior to any anticipated impact on its operating systems. 
The Company believes that with modifications to existing software and
conversions to new software, the Year 2000 issue will not pose significant
operational problems for its computer systems.  However, if such modifications
and conversions are not made, or are not completed timely, the Year 2000 issue
could have a material impact on the operations of the Company.

     The costs of the project and the date on which the Company believes it will
complete the Year 2000 modifications are based on management's best estimates,
which were derived utilizing numerous assumptions of future events, including
the continuous availability of certain resources and other factors.  However,
there can be no guarantee that these estimates will be achieved and actual
results could differ materially from those anticipated.  Specific factors that
might cause such material differences include, but are not limited to, the
availability and cost of personnel trained in this area, the ability to locate
and correct all relevant computer codes, and similar uncertainties.

     GENERAL.  Sales of networking products fluctuate, from time to time, based
on numerous factors, including customers' capital spending levels and general
economic conditions.  While certain industry analysts believe that there is a
significant market for network intelligent hubs, switches, management and
security products there can be no assurance as to the rate or extent of the
growth of such market or the potential adoption of alternative technologies. 
Future declines in networking product sales as a result of general economic
conditions, adoption of alternative technologies or any other reason could have
a material adverse effect on the Company's business, operating results and
financial condition.

     Due to the factors noted above and elsewhere in this Form 10-K and other 
filings with the Securities and Exchange Commission, the Company's future 
earnings and stock price may be subject to significant volatility, 
particularly on a quarterly basis.  Past financial performance should not be 
considered a reliable indicator of future performance and investors should 
not use historical trends to anticipate results or trends in future periods.  
Any shortfall in revenue and earnings from the levels anticipated by 
securities analysts could have an immediate and significant effect on the 
trading price of the Company's common stock in any given period.  Also, the 
Company participates in a highly dynamic industry which often results in 
volatility of the Company's common stock price.

ITEM 2.  PROPERTIES.

     The Company's headquarters is located in a modern, two-story building in
Richardson, Texas, with an aggregate of approximately 95,000 square feet of
floor space.  This facility includes the Company's corporate administration,
manufacturing, marketing, sales and technical support personnel.  The Company
occupies this facility under a lease, the base term of which expires in February
2005, with two seven-year options to extend the lease term, subject to
compliance with certain conditions. The Company owns a one-story building
consisting of approximately 50,000 square feet of floor space adjacent to the
Company's headquarters, and the Company's research and development staff are
located in this facility.  The Company also leases a separate warehouse facility
consisting of approximately 8,000 square feet adjacent to its headquarters under
a lease which expires in June 2000. 


                                         13

<PAGE>

     In addition, the Company and its subsidiaries lease small amounts of office
space for sales and technical support personnel domestically in California,
Colorado, Georgia, Illinois, Massachusetts, Michigan, Minnesota, New York, Ohio,
Pennsylvania, Texas, Virginia and Washington, and  internationally in Australia,
Canada, England, France, Germany, Malaysia, Singapore, South Korea and Taiwan
R.O.C.  The Company believes that these existing facilities will be adequate to
meet its requirements through 1998. See Note 5 of Notes to Consolidated
Financial Statements for additional information regarding the Company's
obligations under leases.

ITEM 3.  LEGAL PROCEEDINGS.

     The Company is not a party to any material litigation and is not aware of
any threatened litigation which would have a material adverse effect on the
Company, its operating results or its financial position.

1997 EMPLOYEE STOCK PURCHASE PLAN 

     The Company has adopted the 1997 Employee Stock Purchase Plan of ODS
Networks, Inc. (the Purchase Plan), which is intended to comply with Section
423(b) of the Code. The Purchase Plan reserves and otherwise provides for the
grant of options to purchase a maximum of 500,000 shares of the Company's Common
Stock, subject to certain adjustments to reflect changes in the Company's
capitalization such as stock splits, stock dividends and similar events. The
Purchase Plan is implemented by an offering during each six-month period ending
January 31 and July 31, respectively, and is administered by the Compensation
Committee of the Board of Directors.  Employees who have worked for the Company
or a subsidiary of the Company for at least 90 days before the beginning of an
offering period are eligible to participate in the Purchase Plan if they are
customarily employed by the Company or a subsidiary of the Company, as defined
in the Purchase Plan.

     The Purchase Plan permits eligible employees to purchase Common Stock
through payroll deductions, which may not exceed 10% of an employee's
compensation.  Each participating employee is granted at the start of a period
an option to purchase shares of Common Stock exercisable at the end of the
period.  The number of shares subject to an option is that number of full shares
that can be purchased with the total amount of payroll deductions for such
employee during the period at the exercise price equal to 85% of the lower of
(i) the closing selling price of Common Stock on the first day of the purchase
period or (ii) the closing selling price on the last day of the purchase period.
Not more than 60,000 shares, plus any unissued shares available from prior
offerings under the Purchase Plan, may be issued each purchase period.

     No participating employee may be granted an option under the Purchase Plan
if such employee, immediately after the option is granted, would own, directly
or indirectly, stock (including the stock to be acquired upon exercise of the
option) representing 5% or more of the total combined voting power of all
classes of capital stock of the Company.  No participating employee may be
granted an option under the Purchase Plan that would permit the purchase of
shares of Common Stock at a rate exceeding $25,000 of fair market value of stock
(determined at the time the option is granted) for each calendar year in which
the option is outstanding.  No participating employee may purchase more than 250
shares per purchase period.

                              ARTICLE ONE--DEFINITIONS


For purposes of the Plan, unless the context or an alternative definition
specified within another Article provides otherwise, the following words and
phrases shall have the definitions provided:


1.1  "ACCOUNT" shall mean the individual bookkeeping accounts maintained for a
Participant under the Plan which shall record (a) the Participant's allocations
of Employer contributions, (b) amounts of Compensation deferred to the Plan
pursuant to the Participant's election, (c) any amounts transferred to this Plan
under Section 4.3 from another qualified retirement plan, and (d) the allocation
of Trust investment experience.


1.2  "ADMINISTRATOR" shall mean the Plan Administrator appointed from time to
time in accordance with the provisions of Article Nine hereof.


1.3  "BENEFICIARY" shall mean any person, trust, organization, or estate
entitled to receive payment under the terms of the Plan upon the death of a
Participant.


1.4  "BREAK IN SERVICE" shall mean the twelve (12)-month computation period
specified in Article Two.


1.5  "CODE" shall mean the Internal Revenue Code of 1986, as amended from time
to time.


1.6  "COMPENSATION" shall mean the compensation paid to a Participant by the
Employer for the Plan Year, but exclusive of stock options, car allowances,
relocation reimbursements, any program of deferred compensation or additional
benefits payable other than in cash and any compensation received prior to his
becoming a Participant in the Plan.  Compensation shall include any amounts
deferred under a salary reduction agreement in accordance with Section 4.1 or
under a Code Section 125 plan maintained by the Employer.

In addition to other applicable limitations set forth in the Plan, and
notwithstanding any other provision of the Plan to the contrary, the annual
Compensation of each Participant taken into account under the Plan shall not
exceed the OBRA '93 annual compensation limit.  The OBRA '93 annual compensation
limit is $150,000, as adjusted by the Secretary of the Treasury or his delegate
for increases in the cost of living in accordance with Section 401(a)(17)(B) of
the Code.  The cost-of-living adjustment in effect for a calendar year applies
to any period, not exceeding twelve (12) months, over which Compensation is
determined (determination period) beginning in such calendar year.  If a
determination period consists of fewer than twelve (12) months, the OBRA '93
annual compensation limit shall be multiplied by a fraction, the numerator of
which is the number of months in the determination period, and the denominator
of which is twelve (12).

Any reference in the Plan to the limitation under Section 401(a)(17) of the Code
shall mean the OBRA '93 annual compensation limit set forth in this provision.

If Compensation for any prior determination period is taken into account in
determining a Participant's benefits accruing in the current Plan Year, the
Compensation for that prior determination period is subject to the OBRA '93
annual compensation limit in effect for that prior determination period.

For purposes of determining who is a Highly-Compensated Employee, Compensation
shall mean compensation as defined in Code Section 414(q)(7).


1.7  "DISABILITY."  Disability shall mean a "permanent and total" disability
incurred by a Participant while in the 


<PAGE>

employ of the Employer.  For this purpose, a permanent and total disability 
shall mean suffering from a physical or mental condition that, in the opinion 
of the Administrator and based upon appropriate medical advice and 
examination, can be expected to result in death or can be expected to last 
for a continuous period of no less than twelve (12) months.  The condition 
must be determined by the Administrator to prevent the Participant from 
engaging in substantial gainful employment.  Receipt of a Social Security 
disability award shall be deemed proof of disability.

1.8  "EFFECTIVE DATE."  The Effective Date of this restated Plan, on and after
which it supersedes the terms of the existing Plan document, is April 1, 1997,
except where the provisions of the Plan shall otherwise specifically provide. 
The rights of any Participant who separated from the Employer's Service prior to
this date shall be established under the terms of the Plan and Trust as in
effect at the time of the Participant's separation from Service, unless the
Participant subsequently returns to Service with the Employer.  Rights of
spouses and Beneficiaries of such Participants shall also be governed by those
documents.


1.9  "EMPLOYEE" shall mean a common law employee of the Employer who, for the
entire period of his employment, was also treated as a common law employee on
the payroll records of the Employer.


1.10  "EMPLOYER"  shall mean ODS Networks, Inc. and any subsidiary or affiliate
which is a member of its "related group" (as defined in Section 2.5) which has
adopted the Plan (a "Participating Affiliate"), and shall include any
successor(s) thereto which adopt this Plan.  Any such subsidiary or affiliate of
ODS Networks, Inc. may adopt the Plan with the approval of its board of
directors (or noncorporate counterpart) subject to the approval of ODS Networks,
Inc.  The provisions of this Plan shall apply equally to each Participating
Affiliate and its Employees except as specifically set forth in the Plan;
provided, however, notwithstanding any other provision of this Plan, the amount
and timing of contributions under Article 4 to be made by any Employer which is
a Participating Affiliate shall be made subject to the approval of ODS Networks,
Inc.  For purposes hereof, each Participating Affiliate shall be deemed to have
appointed ODS Networks, Inc. as its agent to act on its behalf in all matters
relating to the administration, amendment, termination of the Plan and the
investment of the assets of the Plan.  For purposes of the Code and ERISA, the
Plan as maintained by ODS Networks, Inc. and the Participating Affiliates shall
constitute a single plan rather than a separate plan of each Participating
Affiliate.  All assets in the Trust shall be available to pay benefits to all
Participants and their Beneficiaries.


1.11  "EMPLOYMENT DATE" shall mean the first date as of which an Employee is
credited with an Hour of Service, provided that, in the case of a Break in
Service, the Employment Date shall be the first date thereafter as of which an
Employee is credited with an Hour of Service.


1.12 "HIGHLY-COMPENSATED EMPLOYEE" shall mean any Employee of the Employer who:

     (a)  was a five percent (5%) owner of the Employer (as defined in Code
          Section 416(i)(1)) during the "determination year" or "look-back
          year"; or

     (b)  earned more than $80,000 (as increased by cost-of-living adjustments)
          of Compensation from the Employer during the "look-back year" and, if
          the Employer elects, was in the top twenty percent (20%) of Employees
          by Compensation for such year.

An Employee who separated from Service prior to the "determination year" shall
be treated as a Highly-Compensated Employee for the "determination year" if such
Employee was a Highly-Compensated Employee when such Employee separated from
Service, or was a Highly-Compensated Employee at any time after attaining
age fifty-five (55).

<PAGE>

For purposes of this Section, the "determination year" shall be the Plan Year
for which a determination is being made as to whether an Employee is a
Highly-Compensated Employee.  The "look-back year" shall be the twelve (12)
month period immediately preceding the "determination year".  However, if
permitted by applicable law and if the Employer shall elect, the "look-back
year" shall be the calendar year ending with or within the Plan Year for which
testing for the determination of which Employees are Highly-Compensated
Employees is being performed, and the "determination year" (if applicable) shall
be the period of time, if any, which extends beyond the "look-back year" and
ends on the last day of the Plan Year for which such testing is being performed
(the "lag period").  If the "lag period" is less than twelve (12) months, the
dollar threshold amounts specified in (b) above shall be pro-rated based upon
the number of months in the "lag period".


1.13  "HOUR OF SERVICE" shall mean:

     (a)  each hour for which an Employee is paid or entitled to payment for the
          performance of duties for the Employer.  These hours shall be credited
          to the Employee for the computation period in which the duties are
          performed; and

     (b)  each hour for which an Employee is paid, or entitled to payment, by
          the Employer on account of a period of time during which no duties are
          performed (irrespective of whether the employment relationship has
          terminated) due to vacation, holiday, illness, incapacity (including
          disability), layoff, jury duty, involuntary military duty, or leave of
          absence.  No more than five hundred and one (501) Hours of Service
          shall be credited under this subsection for any single continuous
          period during which no duties are performed (whether or not such
          period occurs in a single computation period).  Hours under this
          subsection shall be calculated and credited pursuant to Section
          2530.200b-2(b) and (c) of the Department of Labor Regulations which
          are incorporated herein by this reference; and

     (c)  each hour for which back pay, irrespective of mitigation of damages,
          is either awarded or agreed to by the Employer.  The same Hours of
          Service shall not be credited both under subsection (a) or subsection
          (b), as the case may be, and under this subsection (c).  These hours
          shall be credited to the Employee for the computation period or
          periods to which the award or agreement pertains rather than the
          computation period in which the award, agreement, or payment is made.

In crediting Hours of Service for Employees who are paid on an hourly basis, the
"actual" method shall be utilized.  For this purpose, the "actual" method shall
mean the determination of Hours of Service from records of hours worked and
hours for which the Employer makes payment or for which payment is due from the
Employer, subject to the limitations enumerated above.  In crediting Hours of
Service for Employees who are not paid on an hourly basis, the "weeks of
employment" method shall be utilized.  Under this method, an Employee shall be
credited with forty-five (45) Hours of Service for each week for which the
Employee would be required to be credited with at least one (1) Hour of Service
pursuant to the provisions enumerated above.


1.14  "LEASED EMPLOYEE" shall mean any person who, pursuant to an agreement
between the Employer and any other person or organization, has performed
services for the Employer (determined in accordance with Code Section 414(n)(6))
on a substantially full-time basis for a period of at least one (1) year and
where such services are performed under the primary direction and control of the
Employer.  A person shall not be considered a Leased Employee if the total
number of Leased Employees does not exceed twenty percent (20%) of the
Nonhighly-Compensated Employees employed by the Employer, and if any such person
is covered by a money purchase pension plan providing (a) a nonintegrated
employer contribution rate of at least ten percent (10%) of compensation, as
defined in Section 11.1(b)(2) of the Plan but including amounts contributed
pursuant to a salary reduction agreement which are excludable from the
employee's gross income under Code Sections 125, 402(g) or 403(b), (b) immediate
participation, and (c) full and immediate vesting.


1.15  "NONHIGHLY-COMPENSATED EMPLOYEE" shall mean an Employee of the Employer
who is not a Highly-Compensated Employee.

<PAGE>

1.16  "NORMAL RETIREMENT DATE" shall mean a Participant's sixty-fifth (65th)
birthday or, if later, the fifth (5th) anniversary of the Participant's
commencement of initial Plan participation.


1.17  "PARTICIPANT" shall mean any Employee who has satisfied the eligibility
requirements of Article Three and who is participating in the Plan.


1.18  "PLAN" shall mean ODS 401(k) Savings Plan, as set forth herein and as may
be amended from time to time.


1.19  "PLAN YEAR" shall mean the twelve (12)-consecutive month period beginning
January 1 and ending December 31.


1.20  "TRUST" shall mean the Trust Agreement entered into between the Employer
and the Trustee forming part of this Plan, together with any amendments thereto.
"Trust Fund" shall mean any and all property held by the Trustee pursuant to the
Trust Agreement, together with income therefrom.


1.21  "TRUSTEE" shall mean the Trustee or Trustees appointed by the Employer,
and any successors thereto.


1.22  "VALUATION DATE" shall mean the date or dates established by the
Administrator for the valuation of the assets of the Plan.  In no event shall
the assets of the Plan be valued less frequently than once each Plan Year.


1.23  "YEAR OF SERVICE" OR "SERVICE" and the special rules with respect to
crediting Service are in Article Two of the Plan.

<PAGE>


                     ARTICLE TWO--SERVICE DEFINITIONS AND RULES


Service is the period of employment credited under the Plan.  Definitions and
special rules related to Service are as follows:


2.1  YEAR OF SERVICE.  An Employee shall be credited with a Year of Service for
each Plan Year in which he is credited with at least one thousand (1,000) Hours
of Service.


2.2  BREAK IN SERVICE.  A Break in Service shall be a twelve (12)-month
computation period (as used for measuring Years of Service) in which an Employee
or Participant is not credited with at least five hundred and one (501) Hours of
Service.


2.3  LEAVE OF ABSENCE.  A Participant on an unpaid leave of absence pursuant to
the Employer's normal personnel policies shall be credited with Hours of Service
at his regularly-scheduled weekly rate while on such leave, provided the
Employer acknowledges in writing that the leave is with its approval.  These
Hours of Service shall be credited only for purposes of determining if a Break
in Service has occurred and, unless specified otherwise by the Employer in
writing, shall not be credited for eligibility to participate in the Plan,
vesting, or qualification to receive an allocation of Employer contributions. 
Hours of Service during a paid leave of absence shall be credited as provided in
Section 1.13.

For any individual who is absent from work for any period by reason of the
individual's pregnancy, birth of the individual's child, placement of a child
with the individual in connection with the individual's adoption of the child,
or by reason of the individual's caring for the child for a period beginning
immediately following such birth or adoption, the Plan shall treat as Hours of
Service, solely for determining if a Break in Service has occurred, the
following Hours of Service:

     (a)  the Hours of Service which otherwise normally would have been credited
          to such individual but for such absence; or

     (b)  in any case where the Administrator is unable to determine the Hours
          of Service, on the basis of an assumed eight (8) hours per day.

In no event shall more than five hundred and one (501) of such hours be credited
by reason of such period of absence.  The Hours of Service shall be credited in
the computation period (used for measuring Years of Service) which starts after
the leave of absence begins.  However, the Hours of Service shall instead be
credited in the computation period in which the absence begins if it is
necessary to credit the Hours of Service in that computation period to avoid the
occurrence of a Break in Service.


2.4  HOURS OF SERVICE ON RETURN TO EMPLOYMENT.  An Employee who returns to
employment after a Break in Service shall retain credit for his pre-Break Years
of Service; provided, however, that if a Participant incurs five (5) or more
consecutive Breaks in Service, any Years of Service performed thereafter shall
not be used to increase the nonforfeitable interest in his Account accrued prior
to such five (5) or more consecutive Breaks in Service.


2.5  SERVICE IN EXCLUDED JOB CLASSIFICATIONS OR WITH RELATED COMPANIES.

     (a)  SERVICE WHILE A MEMBER OF AN INELIGIBLE CLASSIFICATION OF EMPLOYEES. 
          An Employee who is a member of an ineligible classification of
          Employees shall not be eligible to participate in the Plan while a
          member of such ineligible classification.  However, if any such
          Employee is transferred to an eligible classification, such Employee
          shall be credited with any prior periods of Service completed while a
          member of such an ineligible classification both for purposes of
          determining his Years of Service and his "Months of Service" under
          Section 3.1.  For this purpose, an Employee shall be considered a
          member of an ineligible classification of Employees 

<PAGE>

          for any period during which:  (i) he is a Leased Employee; or (ii) 
          he is employed in a job classification which is excluded from 
          participating in the Plan under Section 3.1 below.

     (b)  SERVICE WITH RELATED GROUP MEMBERS.  For each Plan Year in which the
          Employer is a member of a "related group", as hereinafter defined, all
          Service of an Employee with any one or more members of such related
          group shall be treated as employment by the Employer for purposes of
          determining the Employee's Years of Service under Section 2.1 and his
          Months of Service under Section 3.1.  The transfer of employment by
          any such Employee to another member of the related group shall not be
          deemed to constitute a retirement or other termination of employment
          by the Employee for purposes of the Plan, but the Employee shall be
          deemed to have continued in employment with the Employer for purposes
          hereof.  For purposes of this subsection (b), "related group" shall
          mean the Employer and all corporations, trades or businesses (whether
          or not incorporated) which constitute a controlled group of
          corporations with the Employer, a group of trades or businesses under
          common control with the Employer, or an affiliated service group which
          includes the Employer, within the meaning  of Section 414(b), Section
          414(c), or Section 414(m), respectively, of the Code or any other
          entity required to be aggregated under Code Section 414(o).

     (c)  CONSTRUCTION.  This Section is included in the Plan to comply with the
          Code provisions regarding the crediting of Service, and not to extend
          any additional rights to Employees in ineligible classifications other
          than as required by the Code and regulations thereunder.
          

<PAGE>

                         ARTICLE THREE--PLAN PARTICIPATION


3.1  PARTICIPATION.  All Employees participating in the Plan prior to the Plan's
restatement shall continue to participate, subject to the terms hereof.  

Each other Employee shall become a Participant under the Plan effective as of
the January 1, April 1, July 1 or October 1 coincident with or next following
the Employee's completion of three (3) Months of Service.  For purposes of this
Section 3.1, an Employee shall be credited with three (3) Months of Service for
each three (3) month period commencing on his Employment Date and the three (3)
month anniversaries of that date and ending on the date he retires, dies or
otherwise separates from Service.  Fractional periods of a month shall be
expressed in terms of days, with thirty (30) days being equal to one (1) month.

In no event, however, shall any Leased Employee, or any Employee who is a
non-resident alien, or an independent contractor, participate under the Plan.


3.2  RE-EMPLOYMENT OF FORMER PARTICIPANT.  A Participant whose participation
ceased because of termination of employment with the Employer shall participate
as soon as administratively possible following his re-employment.


3.3 TERMINATION OF ELIGIBILITY.  In the event a Participant is no longer a
member of an eligible class of Employees and he becomes ineligible to
participate, such Employee shall participate as soon as administratively
possible following his return to an eligible class of Employees.

In the event an Employee who is not a member of an eligible class of Employees
becomes a member of an eligible class, such Employee shall participate as soon
as administratively possible thereafter, if such Employee has satisfied the
eligibility requirements of Section 3.1 and would have otherwise previously
become a Participant.

             ARTICLE FOUR--ELECTIVE DEFERRALS, EMPLOYER CONTRIBUTIONS,
                      ROLLOVERS AND TRANSFERS FROM OTHER PLANS


4.1  ELECTIVE DEFERRALS.

     (a)  ELECTIONS.  A Participant may elect to defer a portion of his
          Compensation for a Plan Year.  The amount of a Participant's
          Compensation that is deferred in accordance with the Participant's
          election shall be withheld by the Employer from the Participant's
          Compensation on a ratable basis throughout the Plan Year.  The amount
          deferred on behalf of each Participant shall be contributed by the
          Employer to the Plan and allocated to the Participant's Account.

     (b)  CHANGES IN ELECTION.  A Participant may prospectively elect to change
          or revoke the amount (or percentage) of his elective deferrals during
          the Plan Year by filing a written election with the Employer, or via a
          telephone "voice response" system designated by the Administrator,
          provided that a written confirmation is forwarded in response to such
          oral request.

     (c)  LIMITATIONS ON DEFERRALS.  No Participant shall defer an amount which
          exceeds $9,500 (or such amount as adjusted for cost-of-living
          increases under Section 402(g) of the Code) for any calendar year
          ending with or within the Plan Year.

     (d)  ADMINISTRATIVE RULES.  All elections made under this Section 4.1,
          including the amount and frequency of deferrals, shall be subject to
          the rules of the Administrator which shall be consistently applied and
          which may be changed from time to time.


4.2  EMPLOYER CONTRIBUTIONS.

     (a)  EMPLOYER MATCHING CONTRIBUTIONS.  For each Plan Year, the Employer may
          contribute to the Plan, on behalf of each Participant, a discretionary
          matching contribution equal to a percentage (as determined by the
          Employer's board of directors) of the elective deferrals made by each
          such Participant.  The amount, if any, of the Employer matching
          contribution for any Plan Year shall be made at the discretion of the
          board of directors of the Employer.  The Employer's board of directors
          may also determine to suspend or reduce its contributions under this
          Section for any Plan Year or any portion thereof.  Allocations under
          this Section shall be subject to the special rules of Section 13.3 in
          any Plan Year in which the Plan is a Top-Heavy Plan (as defined in
          Section 13.2(c)).

     (b)  ADDITIONAL EMPLOYER CONTRIBUTIONS.  Additional Employer contributions
          may be made at the discretion of the Employer's board of directors for
          any Plan Year, subject to limits for tax deductions under the Code and
          provided that the special allocation in Section 13.3 has been
          satisfied if the Plan is a Top-Heavy Plan (as defined in Section
          13.2(c)).

     (c)  ELIGIBILITY FOR ADDITIONAL EMPLOYER CONTRIBUTIONS.  To be eligible for
          an allocation of additional Employer contributions under Section
          4.2(b) for a Plan Year, a Participant must have been credited with at
          least one thousand (1,000) Hours of Service in the Plan Year;
          provided, however, that if the Participant's failure to be credited
          with at least one thousand (1,000) Hours of Service is due to the
          Participant's Disability, death or retirement on or after his Normal
          Retirement Date during the Plan Year, such Participant shall
          nevertheless be entitled to share in the allocation of any additional
          Employer contributions for such Plan Year.

     (d)  ALLOCATION OF ADDITIONAL EMPLOYER CONTRIBUTIONS.  Any contribution
          made under Section 4.2(b) shall be allocated among the Accounts of
          eligible Participants in accordance with the ratio that each such
          eligible Participant's Compensation bears to the total Compensation of
          all such eligible Participants for the Plan Year.

<PAGE>

     (e)  Notwithstanding anything herein to the contrary, in any situation
          where the exclusion of certain Participants from receiving an
          allocation of any additional Employer contributions hereunder would
          result in the Plan failing to satisfy minimum coverage requirements
          under applicable provisions of the Code or income tax regulations,
          then the following shall apply:

          (1)  Such affected Participants shall receive an allocation of
               additional Employer contributions in order of priority based upon
               the number of Hours of Service rendered during the Plan Year by
               each Participant, so that an individual Participant who has
               rendered more Hours of Service during the Plan Year shall be
               first deemed an eligible Participant, and so on, until the
               minimum required number of eligible Participants is reached to
               satisfy the requirements for qualification of this Plan.

          (2)  If two individuals referred to in subsection (1) have the same
               number of Hours of Service, then they shall be deemed eligible
               Participants in order of a priority based upon the earliest
               Employment Date with the Employer.


4.3  ROLLOVERS AND TRANSFERS OF FUNDS FROM OTHER PLANS.  With the approval of
the Administrator, there may be paid to the Trustee amounts which have been held
under other plans qualified under Code Section 401 either (a) maintained by the
Employer which have been discontinued or terminated with respect to any
Employee, or (b) maintained by another employer with respect to which any
Employee has ceased to participate.  Any such transfer or rollover may also be
made by means of an Individual Retirement Account qualified under Section 408 of
the Code, where the Individual Retirement Account was used as a conduit from the
former plan.  Any amounts so transferred on behalf of any Employee shall be
nonforfeitable and shall be maintained under a separate Plan account, to be paid
in addition to amounts otherwise payable under this Plan.  The amount of any
such account shall be equal to the fair market value of such account as adjusted
for income, expenses, gains, losses, and withdrawals attributable thereto.

Notwithstanding anything contained herein to the contrary, in no event shall the
Administrator accept on behalf of any Employee a transfer of funds from a
qualified plan which would subject the Plan to the provisions of Section
401(a)(11) of the Code.

An Employee who would otherwise be eligible to participate in the Plan but for
the failure to satisfy the age and/or service requirement for participation as
set forth under Section 3.1, shall be eligible to complete a rollover to the
Plan.  Such an Employee shall also be eligible to obtain a loan or withdrawal in
accordance with the provisions of Article Eight prior to satisfying such age
and/or service requirement.


4.4  TIMING OF CONTRIBUTIONS.  Employer contributions shall be made to the Plan
no later than the time prescribed by law for filing the Employer's Federal
income tax return (including extensions) for its taxable year ending with or
within the Plan Year.  Elective deferrals under Section 4.1 shall be paid to the
Plan as soon as administratively possible, but no later than the time prescribed
by applicable law, following receipt of such deferrals by the Administrator.

<PAGE>

                           ARTICLE FIVE--ACCOUNTING RULES


5.1  INVESTMENT OF ACCOUNTS AND ACCOUNTING RULES.

     (a)  INVESTMENT FUNDS.  The investment of Participants' Accounts shall be
          made in a manner consistent with the provisions of the Trust.  The
          Administrator, in its discretion, may allow the Trust to provide for
          separate funds for the directed investment of each Participant's
          Account, including an Employer stock fund.

     (b)  PARTICIPANT DIRECTION OF INVESTMENTS.  In the event Participants'
          Accounts are subject to their investment direction, each Participant
          may direct how his Account is to be invested among the available
          investment funds in the percentage multiples established by the
          Administrator.  In the event a Participant fails to make an investment
          election, with respect to all or any portion of his Account, the
          Trustee shall invest all or such portion of his Account in the
          investment fund to be designated by the Administrator.  A Participant
          may change his investment election, with respect to future
          contributions and, if applicable, forfeitures, and/or amounts
          previously accumulated in the Participant's Account, in writing, on
          such form as the Administrator shall specify, or via a telephone
          "voice response" system designated by the Administrator, provided that
          a written confirmation is forwarded in response to such oral request. 
          Any such change in a Participant's investment election shall be
          effective at such time as may be prescribed by the Administrator.  If
          the Plan's recordkeeper or investment manager is changed, the
          Administrator may suspend the Participants' investment direction of
          their Accounts.

     (c)  ALLOCATION OF INVESTMENT EXPERIENCE.  As of each Valuation Date, the
          investment fund(s) of the Trust shall be valued at fair market value,
          and the income, loss, appreciation and depreciation (realized and
          unrealized), and any paid expenses of the Trust attributable to such
          fund shall be apportioned among Participants' Accounts within the fund
          based upon the value of each Account within the fund as of the
          preceding Valuation Date.

     (d)  ALLOCATION OF CONTRIBUTIONS.  Employer contributions shall be
          allocated to the Account of each eligible Participant as of the last
          day of the period for which the contributions are made or as soon as
          administratively practical thereafter.  Elective deferrals shall be
          allocated to the Account of each Participant as soon as
          administratively practical following receipt of such contributions by
          the Administrator.

     (e)  MANNER AND TIME OF DEBITING DISTRIBUTIONS.  For any Participant who is
          entitled to receive a distribution from his Account, such distribution
          shall be made in accordance with the provisions of Section 7.2.  The
          amount distributed shall be based upon the fair market value of the
          Participant's vested Account as of the Valuation Date preceding the
          distribution.


5.2  PARTICIPANTS OMITTED IN ERROR.  In the event a Participant is not allocated
a share of the Employer contribution as a result of an administrative error in
any Plan Year, the Employer may elect to either (a) make an additional
contribution on behalf of such omitted Participant in an appropriate amount, or
(b) deduct the appropriate amount from the next succeeding Employer contribution
and/or forfeitures and allocate such amount to the Participant's Account prior
to making the allocations set forth under Section 5.1(d).

<PAGE>

              ARTICLE SIX--VESTING, RETIREMENT AND DISABILITY BENEFITS


6.1  VESTING.  A Participant shall at all times have a nonforfeitable 
(vested) right to his Account derived from elective deferrals, Employer 
"fail-safe" contributions under Section 10.2, and rollovers or transfers from 
other plans, as adjusted for investment experience.  Except as otherwise 
provided with respect to Normal Retirement, Disability, or death, a 
Participant shall have a nonforfeitable (vested) right to a percentage of the 
value of his Account derived from Employer matching contributions under 
Section 4.2(a) and additional Employer contributions under Section 4.2(b) as 
follows:

<TABLE>
<CAPTION>
     YEARS OF SERVICE             VESTED PERCENTAGE
     <S>                           <C>
     LESS THAN 1 YEAR                 0%
     1 YEAR BUT LESS THAN 2          20%
     2 YEARS BUT LESS THAN 3         40%
     3 YEARS BUT LESS THAN 4         60%
     4 YEARS BUT LESS THAN 5         80%
     5 YEARS AND THEREAFTER         100%
</TABLE>


6.2  FORFEITURE OF NONVESTED BALANCE.  The nonvested portion of a Participant's
Account, as determined in accordance with Section 6.1, shall be forfeited as of
the earlier of (i) the date on which the Participant receives distribution of
his vested Account or (ii) the last day of the Plan Year in which the
Participant incurs five (5) consecutive Breaks in Service.  The amount forfeited
shall be used to reduce Employer contributions under Section 4.2.

If the Participant returns to the employment of the Employer prior to incurring
five (5) consecutive Breaks in Service, and prior to receiving distribution of
his vested Account, the nonvested portion shall be restored.  However, if the
nonvested portion of the Participant's Account was allocated as a forfeiture as
the result of the Participant receiving distribution of his vested Account
balance, the nonvested portion shall be restored if:

     (a)  the Participant resumes employment prior to incurring five (5)
          consecutive Breaks in Service; and

     (b)  the Participant repays to the Plan, as of the earlier of (i) the date
          which is five (5) years after his reemployment date or (ii) the date
          which is the last day of the period in which the Participant incurs
          five (5) consecutive Breaks in Service, an amount equal to the total
          distribution derived from Employer contributions under Section 4.2
          and, if applicable, Section 13.3.

The nonvested amount shall be restored to the Participant's Account, without
interest or adjustment for interim Trust valuation experience, by a special
Employer contribution or from the next succeeding Employer contribution and
forfeitures, as appropriate.


6.3  RETURN TO EMPLOYMENT BEFORE DISTRIBUTION OF VESTED ACCOUNT BALANCE.  If
distribution is made to an Employee of less than the Employee's entire vested
Account, and if the Employee returns to Service, a separate record shall be
maintained of said Account balance.  The Employee's vested interest at any time
in this separate account shall be an amount equal to the formula P(AB+D)-D,
where P is the vested percentage at the relevant time, AB is the Account balance
at the relevant time, and D is the amount of the distribution made to the
Employee.


6.4  NORMAL RETIREMENT.  A Participant who is in the employment of the Employer
at his Normal Retirement Date shall have a nonforfeitable interest in one
hundred percent (100%) of his Account, if not otherwise one hundred percent
(100%) vested under the vesting schedule in Section 6.1.  A Participant who
continues employment with the Employer after his Normal Retirement Date shall
continue to participate under the Plan.

<PAGE>


6.5  DISABILITY.  If a Participant incurs a Disability, the Participant shall
have a nonforfeitable interest in one hundred percent (100%) of his Account, if
not otherwise one hundred percent (100%) vested under the vesting schedule in
Section 6.1.  Payment of such Participant's Account balance shall be made at the
time and in the manner specified in Article Seven, following receipt by the
Administrator of the Participant's written distribution request.

<PAGE>

              ARTICLE SEVEN--MANNER AND TIME OF DISTRIBUTING BENEFITS


7.1  MANNER OF PAYMENT.  The Participant's vested Account shall be distributed
to the Participant (or to the Participant's Beneficiary in the event of the
Participant's death) by any of the following methods, as elected by the
Participant or, when applicable, the Participant's Beneficiary:

     (a)  in a single lump-sum payment; or

     (b)  provided the Participant's vested Account exceeds $3,500, in monthly,
          quarterly, semi-annual or annual installments, subject to the minimum
          distribution rules of Section 7.4.

However, if any portion of a Participant's vested Account is invested in the
Employer stock fund, the Participant may elect to receive such portion of his
Account, in a single sum payment, in the form of shares of stock; provided,
however, that fractional shares and the cash equivalent portions of such fund
shall be distributed in cash.


7.2  TIME OF COMMENCEMENT OF BENEFIT PAYMENTS.  Distribution of the
Participant's Account balance for a Participant who terminates employment on or
after his Normal Retirement Date, or as a result of his Disability, may be made
or commence as soon as administratively possible thereafter; provided, however,
that if the amount required to be distributed cannot be ascertained by such
date, distribution shall be made no later than sixty (60) days after the
earliest date on which such amount can be ascertained; and provided, further,
that, subject to the following provisions of this Section 7.2, distribution
shall not be made or commence unless the Participant otherwise requests in
writing.  In such event, distribution shall commence as soon as administratively
practical following receipt by the Administrator of the Participant's written
request.

Subject to the following provisions of this Section 7.2, if a Participant
terminates employment for any reason other than Normal Retirement, Disability or
death, distribution of his vested Account shall not be made or commence unless
the Participant otherwise requests in writing.

Notwithstanding any provision contained herein to the contrary, a Participant
who is not vested in any portion of his Account balance attributable to Employer
contributions shall be deemed to have received distribution of such portion of
his Account as of the end of the Plan Year in which he incurs a Break in
Service.

A Participant who terminates employment after his Normal Retirement Date may
elect to defer receipt of his Account.  In no event, however, shall distribution
under the Plan be made or commence later than the April 1st following the end of
the calendar year in which the Participant attains age seventy and one-half
(70-1/2) or, except for a Participant who is a five percent (5%) owner of the
Employer (within the meaning of Section 401(a)(9) of the Code), if later, the
April 1st following the calendar year in which the Participant retires or
otherwise separates from Service.


7.3  FURNISHING INFORMATION.  Prior to the payment of any benefit under the
Plan, each Participant or Beneficiary may be required to complete such
administrative forms and furnish such proof as may be deemed necessary or
appropriate by the Employer, Administrator, and/or Trustee.


7.4  MINIMUM DISTRIBUTION RULES FOR INSTALLMENT PAYMENTS.  If a distribution is
made in installments the following rules shall apply:

     (a)  PAYMENTS TO PARTICIPANT OR TO PARTICIPANT AND SURVIVING SPOUSE. 
          Payment shall commence no later than a date provided for in Section
          7.2.  The amount to be distributed each year shall be at least equal
          to the vested balance in the Participant's Account as of the preceding
          Valuation Date multiplied by the following fraction:  the numerator
          shall be one (1) and the denominator shall be the life expectancy of
          the Participant (or the joint life 

<PAGE>

          expectancies of the Participant and the Participant's spouse) 
          determined as of the Valuation Date preceding the first payment and 
          reduced by one for each succeeding year.

     (b)  PAYMENTS TO PARTICIPANT AND NON-SPOUSE BENEFICIARY.  Payment shall
          commence no later than a date provided for in Section 7.2.  The amount
          to be distributed each year shall be at least equal to the vested
          balance in the Participant's Account as of the preceding Valuation
          Date multiplied by the following fraction:  the numerator shall be one
          (1) and the denominator shall be the joint life expectancies of the
          Participant and the Participant's Beneficiary computed as of the
          Valuation Date preceding the first payment and reduced by one (1) for
          each succeeding year.  Payments shall be restricted under this option
          to insure compliance with the minimum distribution incidental death
          benefit requirement of Section 401(a)(9) of the Code and the
          regulations promulgated thereunder.

     (c)  PAYMENTS TO BENEFICIARY.  Payment shall commence no later than a date
          provided for in Section 7.7.  The amount to be distributed each year
          shall be at least equal to the vested balance in the Participant's
          Account as of the preceding Valuation Date multiplied by the following
          fraction:  the numerator shall be one (1) and the denominator shall be
          the life expectancy of the Participant's Beneficiary computed as of
          the Valuation Date preceding the first payment and reduced by one (1)
          for each succeeding year.

     (d)  RECALCULATION OF LIFE EXPECTANCY.  If distribution is to be made over
          the life expectancy of the Participant or, where the Participant's
          spouse is his Beneficiary, the life expectancy of the Participant's
          surviving spouse, or the joint life expectancies of the Participant
          and his spouse, such life expectancy or joint life expectancies, at
          the election of the Participant or his surviving spouse, as the case
          may be, may be recalculated annually.  Any such election shall be
          irrevocable as to the Participant (and spouse, if applicable) and
          shall apply to all subsequent years.  In no event, however, shall the
          life expectancy of a non-spouse Beneficiary be recalculated.


7.5  AMOUNT OF DEATH BENEFIT.

     (a)  DEATH BEFORE TERMINATION OF EMPLOYMENT.  In the event of the death of
          a Participant while in the employ of the Employer, vesting in the
          Participant's Account shall be one hundred percent (100%), if not
          otherwise one hundred percent (100%) vested under Section 6.1, with
          the credit balance of the Participant's Account being payable to his
          Beneficiary.

     (b)  DEATH AFTER TERMINATION OF EMPLOYMENT.  In the event of the death of a
          former Participant after termination of employment, but prior to the
          complete distribution of his vested Account balance under the Plan,
          the undistributed vested balance of the Participant's Account shall be
          paid to the Participant's Beneficiary.


7.6  DESIGNATION OF BENEFICIARY.  Each Participant shall file with the
Administrator a designation of Beneficiary to receive payment of any death
benefit payable hereunder if such Beneficiary should survive the Participant. 
However, no Participant who is married shall be permitted to designate a
Beneficiary other than his spouse unless the Participant's spouse has signed a
written consent witnessed by a Plan representative or a notary public, which
provides for the designation of an alternate Beneficiary.

Subject to the above, Beneficiary designations may include primary and
contingent Beneficiaries, and may be revoked or amended at any time in similar
manner or form, and the most recent designation shall govern.  In the absence of
an effective designation of Beneficiary, or if the Beneficiary dies before
complete distribution of the Participant's vested Account, all amounts shall be
paid to the surviving spouse of the Participant, if living, or otherwise to the
Participant's estate.  Notification to Participants of the death benefits under
the Plan and the method of designating a Beneficiary shall be given at the time
and in the manner provided by regulations and rulings under the Code.


7.7  DISTRIBUTION OF DEATH BENEFITS.  Distribution of any death benefit
hereunder shall be made within one (1) year of the Participant's death or, 


<PAGE>

in the case of a surviving spouse, within a reasonable time after the 
Participant's death or, if the surviving spouse so elects and if the 
Participant's vested Account exceeds $3,500, no later than the date on which 
the Participant would have reached age seventy and one-half (70-1/2).  If a 
surviving spouse dies before distributions to the spouse begin, this 
paragraph shall be applied as if the surviving spouse were the Participant.

To the extent payments are not designated to or for the benefit of a natural
person, or if payments commence after the required time, the following
distribution modes shall be available:

     (a)  a lump sum payable at any time within five (5) years of the
          Participant's death; and

     (b)  payments of installments at such time and in such amount as determined
          by the Beneficiary, provided that all amounts must be paid from the
          Trust within five (5) years of the Participant's death.

If a Participant dies after payments have commenced, any survivor's benefit must
be paid no less rapidly than the method of payment in effect at the time of the
Participant's death.


7.8  ELIGIBLE ROLLOVER DISTRIBUTIONS.  Notwithstanding the foregoing provisions
of this Article Seven, the provisions of this Section 7.8 shall apply to
distributions made under the Plan.

     (a)  A distributee may elect, at the time and in the manner prescribed by
          the Administrator, to have any portion of an eligible rollover
          distribution paid directly to an eligible retirement plan specified by
          the distributee in a direct rollover.

     (b)  Definitions:

          (i)    ELIGIBLE ROLLOVER DISTRIBUTION.  An eligible rollover
                 distribution is any distribution of all or any portion of the
                 balance to the credit of the distributee, except that an
                 eligible rollover distribution does not include:  any
                 distribution that is one of a series of substantially equal
                 periodic payments (not less frequently than annually) made for
                 the life (or life expectancy) of the distributee or the joint
                 lives (or joint life expectancies) of the distributee and the
                 distributee's designated Beneficiary, or for a specified period
                 of ten (10) years or more; any distribution to the extent such
                 distribution is required under Section 401(a)(9) of the Code;
                 and the portion of any distribution that is not includable in
                 gross income (determined without regard to the exclusion for
                 net unrealized appreciation with respect to employer
                 securities).

          (ii)   ELIGIBLE RETIREMENT PLAN.  An eligible retirement plan is an
                 individual retirement account described in Section 408(a) of
                 the Code, an individual retirement annuity described in Section
                 408(b) of the Code, an annuity plan described in Section 403(a)
                 of the Code or a qualified trust described in Section 401(a) of
                 the Code, that accepts the distributee's eligible rollover
                 distribution.  However, in the case of an eligible rollover
                 distribution to the surviving spouse, an eligible retirement
                 plan is an individual retirement account or individual
                 retirement annuity.

          (iii)  DISTRIBUTEE.  A distributee includes an Employee or former
                 Employee.  In addition, the Employee's or former Employee's
                 surviving spouse and the Employee's or former Employee's spouse
                 or former spouse who is the alternate payee under a qualified
                 domestic relations order, as defined in Section 414(p) of the
                 Code, are distributees with regard to the interest of the
                 spouse or former spouse.

          (iv)   DIRECT ROLLOVER.  A direct rollover is a payment by the Plan to
                 the eligible retirement plan specified by the distributee.

     (c)  If a distribution is one to which Sections 401(a)(11) and 417 of the
          Code do not apply, such distribution may commence less than 30 days
          after the notice required under Section 1.411(a)-11(c) of the Income
          Tax Regulations is given, provided that:

<PAGE>

          (i)    the Administrator clearly informs the Participant that the
                 Participant has a right to a period of at least 30 days after
                 receiving the notice to consider the decision of whether or not
                 to elect a distribution (and, if applicable, a particular
                 distribution option), and

          (ii)   the Participant, after receiving the notice, affirmatively
                 elects a distribution.
          

<PAGE>

                  ARTICLE EIGHT--LOANS AND IN-SERVICE WITHDRAWALS


8.1  LOANS.

     (a)  PERMISSIBLE AMOUNT AND PROCEDURES.  Upon the application of a
          Participant, the Administrator may, in accordance with a uniform and
          nondiscriminatory policy, direct the Trustee to grant a loan to the
          Participant, which loan shall be secured by the Participant's vested
          Account balance.  The Participant's signature shall be required on a
          promissory note.  In determining a rate of interest on such loan, the
          Administrator may refer to the rate of interest used for obligations
          of a comparable nature by commercial lending institutions within a
          radius of fifty (50) miles of the Employer's principal place of
          business.  Participant loans shall be treated as segregated
          investments, and interest repayments shall be credited only to the
          Participant's Account.  

     (b)  LIMITATION ON AMOUNT OF LOANS.  A Participant's loan shall not exceed
          the lesser of:

          (1)  $50,000, which amount shall be reduced by the highest outstanding
               loan balance during the preceding twelve (12)-month period; or

          (2)  one-half (1/2) of the vested value of the Participant's Account
               (excluding any portion thereof invested in the Employer stock
               fund), determined as of the Valuation Date preceding the date of
               the Participant's loan.

Any loan must be repaid within five (5) years, unless made for the purpose of
acquiring the primary residence of the Participant, in which case such loan may
be repaid over a longer period of time not to exceed fifteen (15) years.  The
repayment of any loan must be made in at least quarterly installments of
principal and interest.  If a Participant defaults on any outstanding loan, the
unpaid balance, and any interest due thereon, shall become due and payable in
accordance with the terms of the underlying promissory note; provided, however,
that such foreclosure on the promissory note and attachment of security shall
not occur until a distributable event occurs in accordance with the provisions
of Article Seven.

If a Participant terminates employment while any loan balance is outstanding,
the unpaid balance, and any interest due thereon, shall become due and payable
in accordance with the terms of the underlying promissory note.  If such amount
is not paid to the Plan, it shall be charged against the amounts that are
otherwise payable to the Participant or the Participant's Beneficiary under the
provisions of the Plan.

In the case of a Participant who has loans outstanding from other plans of the
Employer (or a member of the Employer's related group (within the meaning of
Section 2.5(b)), the Administrator shall be responsible for reporting to the
Trustee the existence of said loans in order to aggregate all such loans within
the limits of Section 72(p) of the Code.


8.2  HARDSHIP DISTRIBUTIONS.  In the case of a financial hardship resulting from
a proven immediate and heavy financial need, a Participant may receive a
distribution not to exceed the lesser of (i) the vested value of the
Participant's Account, without regard to earnings on his elective deferrals, and
excluding any amounts invested in the Employer stock fund, determined as of the
Valuation Date immediately preceding such withdrawal request, or (ii) the amount
necessary to satisfy the financial hardship.  The amount of any such immediate
and heavy financial need may include any amounts necessary to pay Federal, state
or local income taxes or penalties reasonably anticipated to result from the
distribution.  Such distribution shall be made in accordance with
nondiscriminatory and objective standards consistently applied by the
Administrator.  Hardship distributions under this Section shall be deemed to be
the result of an immediate and heavy financial need if such distribution is to
(a) pay expenses for medical care (as described in Section 213(d) of the Code)
previously incurred by the Participant, the Participant's spouse, or any
dependents of the Participant (as defined in Section 152 of the Code), or to
permit the Participant, the Participant's spouse, or any dependents of the
Participant to obtain such medical care, (b) purchase the principal residence of
the Participant (excluding mortgage payments), (c) pay tuition and related
educational fees for the next twelve (12) months of post-secondary education for
the Participant, Participant's spouse, or any of the Participant's dependents or
(d) prevent the eviction of the Participant from his principal residence or
foreclosure on the Participant's principal residence.  Distributions paid
pursuant to this Section shall be deemed to be made 


<PAGE>

as of the Valuation Date immediately preceding the hardship distribution, and 
the Participant's Account shall be reduced accordingly.

The provisions of this Section (relating to hardship distributions) are intended
to comply with Treasury Regulations issued under Section 401(k) of the Code, and
shall be so interpreted.

No hardship distribution shall be made pursuant to this Section unless the
Administrator, based upon the Participant's representation and such other facts
as are known to the Administrator, determines that the following conditions are
satisfied:

     (a)  The distribution is not in excess of the amount of the immediate and
          heavy financial need of the Participant; and

     (b)  The Participant has obtained all distributions, other than hardship
          distributions, and all non-taxable loans currently available under all
          plans maintained by the Employer.

Following a hardship distribution, the Participant's elective deferrals shall be
suspended under the Plan, and all other plans maintained by the Employer, for at
least twelve (12) months after receipt of the hardship distribution.  In
addition, the Participant's elective deferrals under the Plan, and all other
plans maintained by the Employer, for the Participant's taxable year immediately
following the taxable year of the hardship distribution shall not exceed an
amount equal to the applicable limit under Code Section 402(g) for such next
taxable year, less the amount of such Participant's elective deferrals for the
taxable year of the hardship distribution.


8.3  WITHDRAWALS AFTER AGE 59-1/2.  After attaining age fifty-nine and
one-half (59-1/2), a Participant, by giving written notice to the Administrator,
may withdraw from the Plan a sum (a) not in excess of the credit balance of his
vested Account, excluding any amounts invested in the Employer stock fund, as of
the Valuation Date preceding such notice and (b) not less than such minimum
amount as the Administrator may establish from time to time to facilitate
administration of the Plan.  Any such withdrawals shall be made in accordance
with nondiscriminatory and objective standards consistently applied by the
Administrator.

<PAGE>

                     ARTICLE NINE --ADMINISTRATION OF THE PLAN


9.1  PLAN ADMINISTRATION.  The Employer shall be the Plan Administrator,
hereinbefore and hereinafter called the Administrator, and "named fiduciary"
(for purposes of Section 402(a)(1) of the Employee Retirement Income Security
Act of 1974, as amended from time to time) of the Plan, unless the Employer, by
action of its board of directors, shall designate a person or committee of
persons to be the Administrator and named fiduciary.  The administration of the
Plan, as provided herein, including a determination of the payment of benefits
to Participants and their Beneficiaries, shall be the responsibility of the
Administrator; provided, however, that the Administrator may delegate any of its
powers, authority, duties or responsibilities to any person or committee of
persons.  In the event more than one party shall act as Administrator, all
actions shall be made by majority decisions.  In the administration of the Plan,
the Administrator may (a) employ agents to carry out nonfiduciary
responsibilities (other than Trustee responsibilities), (b) consult with
counsel, who may be counsel to the Employer, and (c) provide for the allocation
of fiduciary responsibilities (other than Trustee responsibilities) among its
members.  Actions dealing with fiduciary responsibilities shall be taken in
writing and the performance of agents, counsel and fiduciaries to whom fiduciary
responsibilities have been delegated shall be reviewed periodically.

The expenses of administering the Plan and the compensation of all employees,
agents, or counsel of the Administrator, including accounting fees,
recordkeeper's fees, and the fees of any benefit consulting firm, shall be paid
by the Plan, or shall be paid by the Employer if the Employer so elects.  To the
extent required by applicable law, compensation may not be paid by the Plan to
full-time Employees of the Employer.

In the event the Employer pays the expenses of administering the Plan, the
Employer may seek reimbursement from the Plan for the payment of such expenses. 
Reimbursement shall be permitted only for Plan expenses paid by the Employer
within the last twelve (12)-month period.

The Administrator shall obtain from the Trustee, not less often than annually, a
report with respect to the value of the assets held in the Trust Fund, in such
form as may be required by the Administrator.

The Administrator shall administer the Plan and adopt such rules and regulations
as, in the opinion of the Administrator, are necessary or advisable to implement
and administer the Plan and to transact its business.


9.2  CLAIMS PROCEDURE.  Pursuant to procedures established by the Administrator,
adequate notice in writing shall be provided to any Participant or Beneficiary
whose claim for benefits under the Plan has been denied within ninety (90) days
of receipt of such claim.  Such notice shall be written in a manner calculated
to be understood by the claimant, shall advise the claimant the right to
administrative review, and shall set forth the specific reason for such denial,
the specific references to the pertinent Plan provisions on which the denial is
based, and a description of any additional material or information necessary to
perfect the claim, and an explanation of why such material or information is
necessary.  If such review is requested by the claimant or his authorized
representative within ninety (90) days after receipt by the claimant of written
notification of denial of his claim, the Administrator shall afford a reasonable
opportunity for a full and fair review by the Administrator of the decision
denying the claim.  The review shall focus on the additional facts, legal
interpretations or material, if any, presented by the claimant.  A hearing at
its place of business may be scheduled by the Administrator, but a hearing is
not required under the review procedure.


9.3  TRUST AGREEMENT.  The Trust Agreement entered into by and between the
Employer and the Trustee, including any supplements or amendments thereto, or
any successor Trust Agreement, is incorporated by reference herein.

<PAGE>

                     ARTICLE TEN--SPECIAL COMPLIANCE PROVISIONS


10.1  DISTRIBUTION OF EXCESS ELECTIVE DEFERRALS.  If the amount of any elective
deferrals made by a Participant exceeds the dollar limitation of Section 4.1(c),
then the excess amount, and any income allocable thereto, shall be distributed
to such Participant subject to the requirements of applicable law.


10.2  LIMITATIONS ON 401(k) CONTRIBUTIONS.

     (a)  AVERAGE ACTUAL DEFERRAL PERCENTAGE TEST.  Amounts contributed as
          elective deferrals under Section 4.1(a), and any "fail-safe"
          contributions made under this Section, are considered to be amounts
          deferred pursuant to Section 401(k) of the Code.  For purposes of this
          Article, these amounts are referred to as the "deferred amounts."  For
          purposes of the "average actual deferral percentage test" described
          below, such deferred amounts must be made before the last day of the
          twelve (12)-month period immediately following the Plan Year to which
          the contributions relate.  The Employer shall maintain records
          sufficient to demonstrate satisfaction of the average actual deferral
          percentage test and the deferred amounts used in such test.

          As of the last day of each Plan Year, the deferred amounts for the
          Plan Year for the Participants who are Highly-Compensated Employees
          shall satisfy either of the following tests:

          (1)  The average actual deferral percentage for the eligible
               Participants who are Highly-Compensated Employees shall not
               exceed the average actual deferral percentage for eligible
               Participants who are Nonhighly-Compensated Employees multiplied
               by 1.25; or

          (2)  The average actual deferral percentage for eligible Participants
               who are Highly-Compensated Employees shall not exceed the average
               actual deferral percentage of eligible Participants who are
               Nonhighly-Compensated Employees multiplied by two (2), provided
               that the average actual deferral percentage for eligible
               Participants who are Highly-Compensated Employees does not exceed
               the average actual deferral percentage for eligible Participants
               who are Nonhighly-Compensated Employees by more than two (2)
               percentage points, or such lesser amount as the Secretary of the
               Treasury shall prescribe to prevent the multiple use of this
               alternative limitation with respect to any Highly-Compensated
               Employee.

For purposes of the above tests, the "actual deferral percentage" shall mean the
ratio (expressed as a percentage) that the deferred amounts, which are allocated
to the Participant's Account as of any day in the Plan Year, on behalf of each
eligible Participant for the Plan Year bears to the eligible Participant's
compensation, as defined in Code Section 414(s) and the regulations promulgated
thereunder.  The "average actual deferral percentage" shall mean the average
(expressed as a percentage) of the actual deferral percentages of the eligible
Participants in each group.  "Eligible Participant" shall mean each Employee who
is eligible to participate in the Plan under Section 3.1.

For purposes of this Section 10.2, the actual deferral percentage for any
eligible Participant who is a Highly-Compensated Employee for the Plan Year and
who is eligible to have elective deferrals allocated to his account under two
(2) or more plans or arrangements described in Code Section 401(k) that are
maintained by the Employer or any employer who is a related group member (within
the meaning of Section 2.5(b)) shall be determined as if all such deferrals were
made under a single arrangement.  In the event that this Plan satisfies the
requirements of Code Section 410(b) only if aggregated  with one (1) or more
other plans, or if one (1) or more other plans satisfy the requirements of Code
Section 410(b) only if aggregated with this Plan, then the provisions of this
Section 10.2 shall be applied by determining the actual deferral percentage of
eligible Participants as if all such plans were a single plan.

The determination and treatment of deferred amounts and the actual deferral
percentage of any Participant shall be subject to the prescribed requirements of
the Secretary of the Treasury.

<PAGE>

In the event the average actual deferral percentage test is not satisfied for a
Plan Year, the Employer, in its discretion, may make a special "fail-safe"
contribution for certain eligible Participants who are Nonhighly Compensated
Employees, to be allocated among their Accounts in proportion to their
Compensation for the Plan Year

     (b)  DISTRIBUTIONS OF EXCESS CONTRIBUTIONS.

          (1)  IN GENERAL.  If the average actual deferral percentage test of
               Section 10.2(a) is not satisfied for a Plan Year, then the
               "excess contributions", and income allocable thereto, shall be
               distributed, to the extent required under Treasury regulations,
               no later than the last day of the Plan Year following the Plan
               Year for which the excess contributions were made.  However, if
               such excess contributions are distributed later than two and
               one-half (2-1/2) months following the last day of the Plan Year
               in which such excess contributions were made, a ten percent (10%)
               excise tax shall be imposed upon the Employer with respect to
               such excess contributions.

               Notwithstanding the foregoing, to the extent otherwise required
               to comply with the requirements of Section 401(a)(4) of the Code
               and the regulations thereunder, vested matching contributions may
               be forfeited.

          (2)  EXCESS CONTRIBUTIONS.  For purposes of this Section, "excess
               contributions" shall consist of the excess of the aggregate
               amount of deferred amounts made by or on behalf of the affected
               Highly-Compensated Employee over the maximum amount of all such
               contributions permitted under the test under Section 10.2(a).  In
               reducing the excess contribution hereunder, the reduction shall
               be first applied to the Highly-Compensated Employee with the
               highest percentage under Section 10.2(a).  If reductions are
               further required to comply with Section 10.2(a), such reductions
               shall be applied to the Highly-Compensated Employee with the next
               highest percentage, and so forth until the nondiscrimination test
               of Section 10.2(a) is satisfied.

          (3)  DETERMINATION OF INCOME.  The income allocable to excess
               contributions shall be determined by multiplying the income
               allocable to the Participant's deferred amounts for the Plan Year
               by a fraction, the numerator of which is the excess contributions
               made on behalf of the Participant for the Plan Year, and the
               denominator of which is the sum of the Participant's Account
               balances attributable to the Participant's deferred amounts on
               the last day of the Plan Year.

          (4)  MAXIMUM DISTRIBUTABLE AMOUNT.  The excess contributions to be
               distributed to a Participant shall be adjusted for income and, if
               there is a loss allocable to the excess contribution, shall in no
               event be less than the lesser of the Participant's Account under
               the Plan or the Participant's deferred amounts for the Plan Year.
               Excess contributions shall be distributed from that portion of
               the Participant's Account attributable to such deferred amounts
               to the extent allowable under Treasury regulations.


10.3  NONDISCRIMINATION TEST FOR EMPLOYER MATCHING CONTRIBUTIONS.

     (a)  AVERAGE CONTRIBUTION PERCENTAGE TEST.  The provisions of this Section
          shall apply if Employer matching contributions are made in any Plan
          Year under Section 4.2(a).

          As of the last day of each Plan Year, the average contribution
          percentage for Highly-Compensated Employees for the Plan Year shall
          satisfy either of the following tests:

          (1)  The average contribution percentage for eligible Participants who
               are Highly-Compensated Employees shall not exceed the average
               contribution percentage for eligible Participants who are
               Nonhighly-Compensated Employees for the Plan Year multiplied by
               1.25; or


<PAGE>

          (2)  The average contribution percentage for eligible Participants who
               are Highly-Compensated Employees shall not exceed the average
               contribution percentage for eligible Participants who are
               Nonhighly-Compensated Employees for the Plan Year multiplied by
               two (2), provided that the average contribution percentage for
               eligible Participants who are Highly-Compensated Employees does
               not exceed the average contribution percentage for eligible
               Participants who are Nonhighly-Compensated Employees by more than
               two (2) percentage points or such lesser amount as the Secretary
               of the Treasury shall prescribe to prevent the multiple use of
               this alternative limitation with respect to any
               Highly-Compensated Employee.

For purposes of the above tests, the "average contribution percentage" shall
mean the average (expressed as a percentage) of the contribution percentages of
the "eligible Participants" in each group.  The contribution percentage" shall
mean the ratio (expressed as a percentage) that the sum of Employer matching
contributions and elective deferrals (to the extent such elective deferrals are
not used to satisfy the average actual deferral percentage test of Section 10.2)
under the Plan on behalf of the eligible Participant for the Plan Year bears to
the eligible Participant's compensation (as defined in Code Section 414(s) and
the regulations promulgated thereunder) for the Plan Year.  "Eligible
Participant" shall mean each Employee who is eligible to participate in the Plan
under Section 3.1.

For purposes of this Section 10.3, the contribution percentage for any eligible
Participant who is a Highly-Compensated Employee for the Plan Year and who is
eligible to have Employer matching contributions or elective deferrals allocated
to his account under two (2) or more plans described in Section 401(a) of the
Code or under arrangements described in Section 401(k) of the Code that are
maintained by the Employer or any member of the Employer's related group (within
the meaning of Section 2.5(b)), shall be determined as if all such contributions
and elective deferrals were made under a single plan.

In the event that this Plan satisfies the requirements of Section 410(b) of the
Code only if aggregated with one (1) or more other plans, or if one (1) or more
other plans satisfy the requirements of Section 410(b) of the Code only if
aggregated with this Plan, then the provisions of this Section 10.3 shall be
applied by determining the contribution percentages of eligible Participants as
if all such plans were a single plan.

The determination and treatment of the contribution percentage of any
Participant shall satisfy such other requirements as may be prescribed by the
Secretary of the Treasury.

     (b)  DISTRIBUTION OF EXCESS EMPLOYER MATCHING CONTRIBUTIONS.

          (1)  IN GENERAL.  If the nondiscrimination tests of Section 10.3(a)
               are not satisfied for a Plan Year, then the "excess
               contributions", and any income allocable thereto, shall be
               forfeited, if otherwise forfeitable, no later than the last day
               of the Plan Year following the Plan Year for which the
               nondiscrimination tests are not satisfied, and shall be used to
               reduce Employer contributions under Section 4.2(a).  To the
               extent that such "excess contributions" are nonforfeitable, such
               excess contributions shall be distributed to the Participant on
               whose behalf the excess contributions were made no later than the
               last day of the Plan Year following the Plan Year for which such
               "excess contributions" were made.  However, if such excess
               contributions are distributed later than two and one-half (2-1/2)
               months following the last day of the Plan Year in which such
               excess contributions were made, a ten percent (10%) excise tax
               shall be imposed upon the Employer with respect to such excess
               contributions.  For purposes of the limitations of Section
               11.1(b)(1) of the Plan, excess contributions shall be considered
               annual additions.

          (2)  EXCESS CONTRIBUTIONS.  For purposes of this Section, "excess
               contributions" shall consist of the excess of the amount of
               Employer matching contributions and elective deferrals (to the
               extent not used to satisfy the average actual deferral percentage
               test of Section 10.2) made on behalf of the affected
               Highly-Compensated Employee over the maximum amount of all such
               contributions permitted under the nondiscrimination tests under
               Section 10.3(a).  In reducing the excess contribution hereunder,
               the reduction shall be first applied to the Highly-Compensated
               Employee with the highest percentage under Section 10.3(a).  If
               reductions are further required to comply with Section 10.3(a),
               such reductions shall be applied to the Highly-Compensated
               Employee with the next highest percentage, and so forth until the
               nondiscrimination tests of Section 10.3(a) are satisfied.


<PAGE>

          (3)  DETERMINATION OF INCOME.  The income allocable to excess
               contributions shall be determined by multiplying the income
               allocable to the Employer matching  contributions and such
               elective deferrals by a fraction, the numerator of which is the
               excess contributions on behalf of the Participant for the Plan
               Year, and the denominator of which is the sum of the
               Participant's Account balances attributable to Employer matching
               contributions and such elective deferrals, on the last day of the
               Plan Year.


10.4  LIMITATION ON THE MULTIPLE USE ALTERNATIVE.  The sum of the average actual
deferral percentage of Highly-Compensated Employees under Section 10.2(a) and
the average contribution percentage of Highly-Compensated Employees under
Section 10.3(a) shall not exceed the "aggregate limit", as defined in
Section 401(m)(9) of the Code and the regulations promulgated thereunder.

If the aggregate limit is exceeded, the average contribution percentage of the
Highly-Compensated Employees shall be reduced in accordance with the provisions
of Section 10.3(b).  In lieu of reducing the average contribution percentage,
the Administrator may reduce the average actual deferral percentage of the
Highly-Compensated Employees in accordance with the provisions of
Section 10.2(b).  The reductions under this Section shall be made only to the
extent necessary to comply with the restrictions on the multiple use of the
"alternative limitation" within the meaning of Code Section 401(m)(9).

                   ARTICLE ELEVEN--LIMITATION ON ANNUAL ADDITIONS


11.1  RULES AND DEFINITIONS.

     (a)  RULES.  The following rules shall limit additions to Participants'
Accounts:

          (1)  If the Participant does not participate, and has never
               participated, in another qualified plan maintained by the
               Employer, the amount of annual additions which may be credited to
               the Participant's Account for any limitation year shall not
               exceed the lesser of the "maximum permissible" amount (as
               hereafter defined) or any other limitation contained in this
               Plan.  If the Employer contribution that would otherwise be
               allocated to the Participant's Account would cause the annual
               additions for the limitation year to exceed the maximum
               permissible amount, the amount allocated shall be reduced so that
               the annual additions for the limitation year shall equal the
               maximum permissible amount.

          (2)  Prior to determining the Participant's actual compensation for
               the limitation year, the Employer may determine the maximum
               permissible amount for a Participant on the basis of a reasonable
               estimation of the Participant's compensation for the limitation
               year, uniformly determined for all Participants similarly
               situated.

          (3)  As soon as is administratively feasible after the end of the
               limitation year, the maximum permissible amount for the
               limitation year shall be determined on the basis of the
               Participant's actual compensation for the limitation year.

          (4)  If there is an excess amount, the excess shall be disposed of as
               follows:

               (A)  Any nondeductible voluntary Employee after-tax contributions
                    and, to the extent elected by the Administrator pursuant to
                    a nondiscriminatory procedure, elective deferrals under
                    Section 4.1(a), and any earnings thereon, to the extent they
                    would reduce the excess amount, shall be returned to the
                    Participant.

               (B)  If an excess amount still exists after the application of
                    subparagraph (A), and the Participant is covered by the Plan
                    at the end of the limitation year, the excess amount in the
                    Participant's Account shall be used to reduce Employer
                    contributions (including any allocation of forfeitures, if
                    applicable) for such Participant in the next limitation
                    year, and each succeeding limitation year if necessary;

               (C)  If an excess amount still exists after the application of
                    subparagraphs (A) and (B), and the Participant is not
                    covered by the Plan at the end of the limitation year, the
                    excess amount shall be held unallocated in a suspense
                    account and applied to reduce future Employer contributions
                    (including allocation of any forfeitures) for all remaining
                    Participants in the next limitation year, and each
                    succeeding limitation year if necessary.

               (D)  If a suspense account is in existence at any time during the
                    limitation year pursuant to this Section 11.1(a)(4), it
                    shall not participate in the allocation of the Trust's
                    investment gains and losses.  In addition, all amounts held
                    in the suspense account shall be allocated and reallocated
                    to Participants' Accounts before any Employer or Employee
                    contributions may be made for the limitation year.

          (5)  If, in addition to this Plan, the Participant is covered under
               another defined contribution plan maintained by the Employer, or
               a welfare benefit fund, as defined in Code Section 419(e),
               maintained by the Employer, or an individual medical account, as
               defined in Code Section 415(1)(2), maintained by the Employer
               which provides an annual addition, the annual additions which may
               be credited to a Participant's account under all such plans for
               any such limitation year shall not exceed the maximum 

<PAGE>

               permissible amount.  Benefits shall be reduced under any 
               discretionary defined contribution plan before they are reduced 
               under any defined contribution pension plan.  If both plans are
               discretionary contribution plans, they shall first be reduced
               under this Plan.  Any excess amount attributable to this Plan
               shall be disposed of in the manner described in Section
               11.1(a)(4).

          (6)  If the Employer maintains, or at any time maintained, a qualified
               defined benefit plan covering any Participant in this Plan, the
               sum of the Participant's defined benefit plan fraction and
               defined contribution plan fraction shall not exceed 1.0 in any
               limitation year.  The annual additions which may be credited to
               the Participant's Account under this Plan for any limitation year
               shall be limited so that if the limitations of Code Section
               415(e) become applicable, benefits under a defined benefit plan
               shall have first been provided before benefits under a defined
               contribution plan are provided.

          (7)  In any Plan Year in which the Plan becomes a Super Top-Heavy Plan
               (as defined in Section 13.2(b)), the denominators of the defined
               benefit fraction and defined contribution fraction shall be
               computed using one hundred percent (100%) of the maximum dollar
               limitation instead of one hundred and twenty-five percent (125%).

          (8)  In any year in which the Plan is a Top-Heavy Plan (as defined in
               Section 13.2(c)) (but not a Super Top-Heavy Plan), the
               limitations shall be similarly reduced, subject to the special
               provisions of Section 13.3, which provide for the use of the one
               hundred and twenty-five percent (125%) limitation subject to the
               added minimum allocations.

     (b)  DEFINITIONS.

          (1)  ANNUAL ADDITIONS:  The following amounts credited to a
               Participant's Account for the limitation year shall be treated as
               annual additions:

               (A)  Employer contributions;

               (B)  Elective deferrals;

               (C)  Employee after-tax contributions, if any;

               (D)  Forfeitures, if any; and

               (E)  Amounts allocated after March 31, 1984 to an individual
                    medical account, as defined in Section 415(l)(2) of the
                    Code, which is part of a defined benefit plan maintained by
                    the Employer.  Also, amounts derived from contributions paid
                    or accrued after December 31, 1985 in taxable years ending
                    after such date which are attributable to post-retirement
                    medical benefits allocated to the separate account of a Key
                    Employee, as defined in Section 419A(d)(3), and amounts
                    under a welfare benefit fund, as defined in Section 419(e),
                    maintained by the Employer, shall be treated as annual
                    additions to a defined contribution plan.

               For this purpose, any excess amount applied under Section
               11.1(a)(4) in the limitation year to reduce Employer
               contributions shall be considered annual additions for such
               limitation year.

          (2)  COMPENSATION:  For purposes of determining maximum permitted
               benefits under this Section, compensation shall include all of a
               Participant's earned income, wages, salaries, and fees for
               professional services, and other amounts received for personal
               services actually rendered in the course of employment with the
               Employer, including, but not limited to, commissions paid to
               salesmen, compensation for services on the basis of a percentage
               of profits, commissions on insurance premiums, tips and bonuses,
               and excluding the following:


<PAGE>

               (A)  Employer contributions to a plan of deferred compensation
                    which are not included in the Employee's gross income for
                    the taxable year in which contributed, or Employer
                    contributions under a simplified employee pension plan
                    (funded with individual retirement accounts or annuities) to
                    the extent such contributions are deductible by the
                    Employee, or any distributions from a plan of deferred
                    compensation;

               (B)  Amounts realized from the exercise of a nonqualified stock
                    option, or when restricted stock (or property) held by the
                    Employee either becomes freely transferable or is no longer
                    subject to a substantial risk of forfeiture;

               (C)  Amounts realized from the sale, exchange, or other
                    disposition of stock acquired under a qualified stock
                    option; and

               (D)  Other amounts which received special tax benefits, or
                    contributions made by the Employer (whether or not under a
                    salary reduction agreement) toward the purchase of an
                    annuity described in Section 403(b) of the Code (whether or
                    not the amounts are actually excludable from the gross
                    income of the Employee).

               Compensation shall be measured on the basis of compensation paid
               in the limitation year.

          (3)  DEFINED BENEFIT FRACTION:  This shall mean a fraction, the
               numerator of which is the sum of the Participant's projected
               annual benefits under all the defined benefit plans maintained or
               previously maintained by the Employer, and the denominator of
               which is the lesser of one hundred and  twenty-five percent
               (125%) of the dollar limitation in effect for the limitation year
               under Section 415(b)(1)(A) of the Code or one hundred and forty
               percent (140%) of the highest average compensation including any
               adjustment under Code Section 415(b).

          (4)  DEFINED CONTRIBUTION FRACTION:  This shall mean a fraction, the
               numerator of which is the sum of the annual additions to the
               Participant's account under all the defined contribution plans
               (whether or not terminated), welfare benefit funds, and
               individual medical accounts maintained by the Employer for the
               current and all prior limitation years, and the denominator of
               which is the sum of the maximum aggregate amounts for the current
               and all prior limitation years of Service with the Employer,
               regardless of whether a defined contribution plan was maintained
               by the Employer.

               The maximum aggregate amount in any limitation year is the lesser
               of one hundred and twenty-five percent (125%) of the dollar
               limitation then in effect under Section 415(c)(1)(A) of the Code
               or thirty-five (35%) of the Participant's compensation for such
               year.

               If the Employee, as of the end of the first day of the first
               limitation year beginning after December 31, 1986, was a
               participant in one (1) or more defined contribution plans
               maintained by the Employer which were in existence on May 5,
               1986, the numerator of this fraction shall be adjusted if the sum
               of this fraction and the defined benefit fraction would otherwise
               exceed 1.0 under the terms of this Plan.  Under the adjustment,
               an amount equal to the product of (i) the excess of the sum of
               the fractions over 1.0 and (ii) the denominator of this fraction,
               will be permanently subtracted from the numerator of this
               fraction.  The adjustment is calculated using the fractions as
               they would be computed as of the end of the last limitation year
               beginning before January 1, 1987, and disregarding any changes in
               the terms and conditions of the Plan made after May 5, 1986, but
               using the Code Section 415 limitation applicable to the first
               limitation year beginning on or after January 1, 1987.

               The annual addition for any limitation year beginning before
               January 1, 1987, shall not be recomputed to treat all Employee
               contributions as annual additions.

          (5)  DEFINED CONTRIBUTION DOLLAR LIMITATION:  This shall mean the
               greater of $30,000 or one-fourth (1/4) of the defined benefit
               dollar limitation of Section 415(b)(1) of the Code in effect for
               the limitation year.

<PAGE>


          (6)  EMPLOYER:  This term refers to the Employer that adopts this
               Plan, and all members of a controlled group of corporations (as
               defined in Section 414(b) of the Code, as modified by Section
               415(h)), commonly-controlled trades or businesses (as defined in
               Section 414(c), as modified by Section 415(h)), or affiliated
               service groups (as defined in Section 414(m)) of which the
               Employer is a part, or any other entity required to be aggregated
               with the Employer under Code Section 414(o).

          (7)  HIGHEST AVERAGE COMPENSATION:  This means the average
               compensation for the three (3) consecutive limitation years with
               the Employer that produces the highest average.

          (8)  LIMITATION YEAR:  This shall mean the Plan Year.

          (9)  MAXIMUM PERMISSIBLE AMOUNT:  This shall mean an amount equal to
               the lesser of the defined contribution dollar limitation or
               twenty-five percent (25%) of the Participant's compensation for
               the limitation year.  If a short limitation year is created
               because of an amendment changing the limitation year to a
               different twelve (12)-consecutive month period, the maximum
               permissible amount shall not exceed the defined contribution
               dollar limitation multiplied by the following fraction:

                   NUMBER OF MONTHS IN THE SHORT LIMITATION YEAR
                   ---------------------------------------------
                                         12

          (10) PROJECTED ANNUAL BENEFIT:  This is the annual retirement benefit
               (adjusted to an actuarially equivalent straight life annuity if
               such benefit is expressed in a form other than a straight life
               annuity or qualified joint and survivor annuity) to which the
               Participant would be entitled under the terms of the plan,
               assuming:

               (A)  the Participant will continue employment until normal
                    retirement age under the plan (or current age, if later),
                    and

               (B)  the Participant's compensation for the current limitation
                    year and all other relevant factors used to determine
                    benefits under the plan will remain constant for all future
                    limitation years.

                       ARTICLE TWELVE--AMENDMENT AND TERMINATION


12.1  AMENDMENT.  The Employer, by resolution of its board of directors, (or, to
the extent permitted by resolution of such board of directors, by action of a
duly authorized officer of the Employer) shall have the right to amend, alter or
modify the Plan at any time, or from time to time, in whole or in part.  Any
such amendment shall become effective under its terms upon adoption by the
Employer.  However, no amendment affecting the duties, powers or
responsibilities of the Trustee may be made without the written consent of the
Trustee.  No amendment shall be made to the Plan which shall:

     (a)  make it possible (other than as provided in Section 14.3) for any part
          of the corpus or income of the Trust Fund (other than such part as may
          be required to pay taxes and administrative expenses) to be used for
          or diverted to purposes other than the exclusive benefit of the
          Participants or their Beneficiaries;

     (b)  decrease a Participant's account balance or eliminate an optional form
          of payment with respect to benefits accrued as of the later of (i) the
          date such amendment is adopted, or (ii) the date the amendment becomes
          effective; or 

     (c)  alter the schedule for vesting in a Participant's Account with respect
          to any Participant with three (3) or more Years of Service without his
          consent or deprive any Participant of any nonforfeitable portion of
          his Account.

Notwithstanding the other provisions of this Section or any other provisions of
the Plan, any amendment or modification of the Plan may be made retroactively if
necessary or appropriate to conform to or to satisfy the conditions of any law,
governmental regulation, or ruling, and to meet the requirements of the Employee
Retirement Income Security Act of 1974, as it may be amended.


12.2  TERMINATION OF THE PLAN.  The Employer, by resolution of its board of
directors, reserves the right at any time and in its sole discretion to
discontinue payments under the Plan and to terminate the Plan.  In the event the
Plan is terminated, or upon complete discontinuance of contributions under the
Plan by the Employer, the rights of each Participant to his Account on the date
of such termination or discontinuance of contributions, to the extent of the
fair market value under the Trust Fund, shall become fully vested and
nonforfeitable.  The Employer shall direct the Trustee to distribute the Trust
Fund in accordance with the Plan's distribution provisions to the Participants
and their Beneficiaries, each Participant or Beneficiary receiving a portion of
the Trust Fund equal to the value of his Account as of the date of distribution.
These distributions may be implemented by the continuance of the Trust and the
distribution of the Participants' Account shall be made at such time and in such
manner as though the Plan had not terminated, or by any other appropriate
method, including rollover into Individual Retirement Accounts.  Upon
distribution of the Trust Fund, the Trustee shall be discharged from all
obligations under the Trust and no Participant or Beneficiary shall have any
further right or claim therein.  If a partial termination of the Plan is deemed
to have occurred, this Section shall apply only to those Participant's affected
by such partial termination.

                       ARTICLE THIRTEEN--TOP-HEAVY PROVISIONS


13.1  APPLICABILITY.  The provisions of this Article shall become applicable
only for any Plan Year in which the Plan is a Top-Heavy Plan (as defined in
Section 13.2(c)).  The determination of whether the Plan is a Top-Heavy Plan
shall be made each Plan Year by the Administrator.


13.2  DEFINITIONS.  For purposes of this Article, the following definitions
shall apply:

     (a)  "KEY EMPLOYEE":  "Key Employee" shall mean any Employee or former
          Employee (and the Beneficiaries of such Employee) who, at any time
          during the determination period, was (1) an officer of the Employer
          earning compensation (as defined in Section 416(i) of the Code) in
          excess of fifty percent (50%) of the dollar limitation under Section
          415(b)(1)(A) of the Code, (2) an owner (or considered an owner under
          Section 318 of the Code) of both more than a one-half percent (1/2%)
          interest in the Employer and one of the ten (10) largest interests in
          the Employer if such individual's compensation exceeds the dollar
          limitation under Section 415(c)(1)(A) of the Code, (3) a five percent
          (5%) owner of the Employer, or (4) a one percent (1%) owner of the
          Employer who has an annual compensation of more than $150,000.  For
          purposes of this Section, annual compensation shall mean compensation
          as defined in Code Section 415(c)(3), but including amounts
          contributed by the Employer pursuant to a salary reduction agreement
          which are excludable from the Employee's income under Code Sections
          125, 402(g), 402(h) or 403(b).  The determination period of the Plan
          is the Plan Year containing the "determination date" as defined in
          Section 13.2(c)(4) and the four (4) preceding Plan Years.

          The determination of who is a Key Employee (including the terms "5%
          owner" and "1% owner") shall be made in accordance with Section
          416(i)(1) of the Code and the regulations thereunder.

     (b)  "SUPER TOP-HEAVY PLAN":  The Plan shall constitute a "Super Top-Heavy
          Plan" if it meets the test for status as a Top-Heavy Plan, where "90%"
          is substituted for "60%" at each place in Section 13.2(c).

     (c)  "TOP-HEAVY PLAN":

          (1)  The Plan shall constitute a "Top-Heavy Plan" if any of the
          following conditions exist:

               (A)  The top-heavy ratio for the Plan exceeds sixty percent (60%)
                    and the Plan is not part of any required aggregation group
                    or permissive aggregation group of plans; or

               (B)  The Plan is part of a required aggregation group of plans
                    (but is not part of a permissive aggregation group) and the
                    top-heavy ratio for the group of plans exceeds sixty percent
                    (60%); or

               (C)  The Plan is a part of a required aggregation group of plans
                    and part of a permissive aggregation group and the top-
                    heavy ratio for the permissive aggregation group exceeds
                    sixty percent (60%).

          (2)  If the Employer maintains one (1) or more defined contribution
               plans (including any simplified employee pension plan funded with
               individual retirement accounts or annuities) and the Employer
               maintains or has maintained one (1) or more defined benefit plans
               which have covered or could cover a Participant in this Plan, the
               top-heavy ratio is a fraction, the numerator of which is the sum
               of account balances under the defined contribution plans for all
               Key Employees and the actuarial equivalents of accrued benefits
               under the defined benefit plans for all Key Employees, and the
               denominator of which is the sum of the account balances under the
               defined contribution plans for all Participants and the actuarial
               equivalents of accrued benefits under the defined benefit plans
               for all Participants.  Both the numerator and denominator of the
               top-heavy ratio shall include any distribution of an account
               balance or an accrued benefit made in the five (5)-year period
               ending on the determination date and any 

<PAGE>

               contribution due to a defined contribution pension plan but 
               unpaid as of the determination date.  In determining the 
               accrued benefit of a non-Key Employee who is participating in 
               a plan that is part of a required aggregation group, the 
               method of determining such benefit shall be either (i) in 
               accordance with the method, if any, that uniformly applies for 
               accrual purposes under all plans maintained by the Employer or 
               any member of the Employer's related group (within the meaning 
               of Section 2.5(b)), or (ii) if there is no such method, as if 
               such benefit accrued not more rapidly than the slowest accrual 
               rate permitted under the fractional accrual rate of Code 
               Section 411(b)(1)(C).

          (3)  For purposes of (1) and (2) above, the value of account balances
               and the actuarial equivalents of accrued benefits shall be
               determined as of the most recent Valuation Date that falls within
               or ends with the twelve (12)-month period ending on the
               determination date.  The account balances and accrued benefits of
               a Participant who is not a Key Employee but who was a Key
               Employee in a prior year shall be disregarded.  The accrued
               benefits and account balances of Participants who have performed
               no Hours of Service with any Employer maintaining the plan for
               the five (5)-year period ending on the determination date shall
               be disregarded.  The calculations of the top-heavy ratio, and the
               extent to which distributions, rollovers, and transfers are taken
               into account shall be made under Section 416 of the Code and
               regulations issued thereunder.  Deductible Employee contributions
               shall not be taken into account for purposes of computing the
               top-heavy ratio.  When aggregating plans, the value of account
               balances and accrued benefits shall be calculated with reference
               to the determination dates that fall within the same calendar
               year.

          (4)  DEFINITION OF TERMS FOR TOP-HEAVY STATUS:

               (A)  "TOP-HEAVY RATIO" shall mean the following:

                    (1)  If the Employer maintains one or more defined
                         contribution plans (including any simplified employee
                         pension plan funded with individual retirement accounts
                         or annuities) and the Employer has never maintained any
                         defined benefit plans which have covered or could cover
                         a Participant in this Plan, the top-heavy ratio is a
                         fraction, the numerator of which is the sum of the
                         account balances of all Key Employees as of the
                         determination date (including any part of any account
                         balance distributed in the five (5)-year period ending
                         on the determination date), and the denominator of
                         which is the sum of the account balances (including any
                         part of any account balance distributed in the five
                         (5)-year period ending on the determination date) of
                         all Participants as of the determination date.  Both
                         the numerator and the denominator shall be increased by
                         any contributions due but unpaid to a defined
                         contribution pension plan as of the determination date.

               (B)  "PERMISSIVE AGGREGATION GROUP" shall mean the required
                    aggregation group of plans plus any other plan or plans of
                    the Employer which, when considered as a group with the
                    required aggregation group, would continue to satisfy the
                    requirements of Section 401(a)(4) and/or 410 of the Code.

               (C)  "REQUIRED AGGREGATION GROUP" shall mean (i) each qualified
                    plan of the Employer (including any terminated plan) in
                    which at least one Key Employee participates, and (ii) any
                    other qualified plan of the Employer which enables a plan
                    described in (i) to meet the requirements of Section
                    401(a)(4) and/or 410 of the Code.

               (D)  "DETERMINATION DATE" shall mean, for any Plan Year
                    subsequent to the first Plan Year, the last day of the
                    preceding Plan Year.  For the first Plan Year of the Plan,
                    "determination date" shall mean the last day of that Plan
                    Year.

               (E)  "VALUATION DATE" shall mean the last day of the Plan Year.

<PAGE>

               (F)  Actuarial equivalence shall be based on the interest and
                    mortality rates utilized to determine actuarial equivalence
                    when benefits are paid from any defined benefit plan.  If no
                    rates are specified in said plan, the following shall be
                    utilized:  pre- and post-retirement interest -- five percent
                    (5%); post-retirement mortality based on the Unisex Pension
                    (1984) Table as used by the Pension Benefit Guaranty
                    Corporation on the date of execution hereof.


13.3  ALLOCATION OF EMPLOYER CONTRIBUTIONS AND FORFEITURES FOR A TOP-HEAVY PLAN
YEAR.

     (a)  Except as otherwise provided below, in any Plan Year in which the Plan
          is a Top-Heavy Plan, the Employer contributions and forfeitures
          allocated on behalf of any Participant who is a non-Key Employee shall
          not be less than the lesser of three percent (3%) of such
          Participant's compensation (as defined in Section 11.1(b)(2)) or the
          largest percentage of Employer contributions and forfeitures as a
          percentage of the Key Employee's Compensation, allocated on behalf of
          any Key Employee for that Plan Year.  This minimum allocation shall be
          made even though, under other Plan provisions, the Participant would
          not otherwise be entitled to receive an allocation or would have
          received a lesser allocation for the Plan Year because of insufficient
          Employer contributions under Section 4.2, the Participant's failure to
          complete one thousand (1,000) Hours of Service or the Participant's
          failure to make elective deferrals under Section 4.1.

     (b)  The minimum allocation under this Section shall not apply to any
          Participant who was not employed by the Employer on the last day of
          the Plan Year.

     (c)  The minimum allocation under this Section shall be offset and reduced
          by any allocation of contributions and forfeitures under Section 4.2,
          and under any other defined contribution plan (if such contributions
          are not matching contributions under Code Section 401(m)) with a Plan
          Year ending in the same calendar year as the Valuation Date.

     (d)  For purposes of the Plan, a non-Key Employee shall be any Employee or
          Beneficiary of such Employee, any former Employee, or Beneficiary of
          such former Employee, who is not or was not a Key Employee during the
          Plan Year ending on the determination date, nor during the four (4)
          preceding Plan Years.

     (e)  If no defined benefit plan has ever been part of a permissive or
          required aggregation group of plans of the Employer, the contributions
          and forfeitures under this step shall be offset by any allocation of
          contributions and forfeitures under any other defined contribution
          plan of the Employer with a Plan Year ending in the same calendar year
          as this Plan's Valuation Date.

     (f)  There shall be no duplication of the minimum benefits required under
          Code Section 416.  Benefits shall be provided under defined
          contribution plans before under defined benefit plans.  If a defined
          benefit plan (active or terminated) is part of the permissive or
          required aggregation group of plans, the allocation method of
          subparagraph (a) above shall apply, except that "3%" shall be
          increased to "5%."

     (g)  There shall be no duplication of the minimum benefits required under
          Code Section 416.  Benefits shall be provided under defined
          contribution plans before defined benefit plans.  If a defined benefit
          plan (active or terminated) is part of the permissive or required
          aggregation group of plans, and if any Participant in the Plan would
          have his benefits limited due to the application of the Code
          limitation rule in Section 11.1 in a Plan Year in which the Plan is a
          Top-Heavy Plan but not a Super Top-Heavy Plan, the allocation method
          of subparagraph (f) above shall apply, except that "5%" shall be
          increased to "7.5%."


13.4  VESTING.  The provisions contained in Section 6.1 relating to vesting
shall continue to apply in any Plan Year in which the Plan is a Top-Heavy Plan,
and apply to all benefits within the meaning of Section 411(a)(7) of the Code
except those attributable to Employee contributions and elective deferrals under
Section 4.1, including benefits accrued before the effective date of Section 416
and benefits accrued before the Plan became a Top-Heavy Plan.  Further, no
reduction in vested benefits may occur in the event the Plan's status as a
Top-Heavy Plan changes for any Plan Year and the vesting 


<PAGE>

schedule is amended. In addition, if a Plan's status changes from a Top-Heavy 
Plan to that of a non-Top-Heavy Plan, a Participant with three (3) Years of 
Service shall continue to have his vested rights determined under the 
schedule which he selects, in the event the vesting schedule is subsequently 
amended.

Payment of a Participant's vested Account balance under this Section shall be
made in accordance with the provisions of Article Seven.

                     ARTICLE FOURTEEN--MISCELLANEOUS PROVISIONS


14.1  PLAN DOES NOT AFFECT EMPLOYMENT.  Neither the creation of this Plan, any
amendment thereto, the creation of any fund nor the payment of benefits
hereunder shall be construed as giving any legal or equitable right to any
Employee or Participant against the Employer, its officers or Employees, or
against the Trustee.  All liabilities under this Plan shall be satisfied, if at
all, only out of the Trust Fund held by the Trustee.  Participation in the Plan
shall not give any Participant any right to be retained in the employ of the
Employer, and the Employer hereby expressly retains the right to hire and
discharge any Employee at any time with or without cause, as if the Plan had not
been adopted, and any such discharged Participant shall have only such rights or
interests in the Trust Fund as may be specified herein.


14.2  SUCCESSOR TO THE EMPLOYER.  In the event of the merger, consolidation,
reorganization or sale of assets of the Employer, under circumstances in which a
successor person, firm, or corporation shall carry on all or a substantial part
of the business of the Employer, and such successor shall employ a substantial
number of Employees of the Employer and shall elect to carry on the provisions
of the Plan, such successor shall be substituted for the Employer under the
terms and provisions of the Plan upon the filing in writing with the Trustee of
its election to do so.


14.3  REPAYMENTS TO THE EMPLOYER.  Notwithstanding any provisions of this Plan
to the contrary:

     (a)  Any monies or other Plan assets attributable to any contribution made
          to this Plan by the Employer because of a mistake of fact shall be
          returned to the Employer within one (1) year after the date of
          contribution.

     (b)  Any monies or other Plan assets attributable to any contribution made
          to this Plan by the Employer shall be refunded to the Employer, to the
          extent such contribution is predicated on the deductibility thereof
          under the Code and the income tax deduction for such contribution is
          disallowed.  Such amount shall be refunded within one (1) taxable year
          after the date of such disallowance or within one (1) year of the
          resolution of any judicial or administrative process with respect to
          the disallowance.  All Employer contributions hereunder are expressly
          contributed based upon such contributions' deductibility under the
          Code.

However, the provisions of this Section shall not apply to elective deferrals
made by a Participant under Section 4.1.


14.4  BENEFITS NOT ASSIGNABLE.  Except as provided in Section 414(p) of the Code
with respect to "qualified domestic relations orders," the rights of any
Participant or his Beneficiary to any benefit or payment hereunder shall not be
subject to voluntary or involuntary alienation or assignment.

With respect to any "qualified domestic relations order" relating to the Plan,
the Plan shall permit distribution to an alternate payee under such order at any
time, irrespective of whether the Participant has attained his "earliest
retirement age" (within the meaning of Section 414(p)(4)(B) of the Code) under
the Plan.  A distribution to an alternate payee prior to the Participant's
attainment of his earliest retirement age shall, however, be available only if: 
(1) the order specifies distribution at that time or permits an agreement
between the Plan and the alternate payee to authorize an earlier distribution;
and (2) if the present value of the alternate payee's benefit under the Plan
exceeds $3,500, the order requires the alternate payee to consent to any
distribution occurring prior to the Participant's attainment of his earliest
retirement age.  Nothing in this paragraph shall, however, give a Participant a
right to receive distribution at a time otherwise not permitted under the Plan
nor does it permit the alternate payee to receive a form of payment not
otherwise permitted under the Plan or under said Section 414(p) of the Code.


14.5  MERGER OF PLANS.  In the case of any merger or consolidation of this Plan
with, or transfer of the assets or liabilities of the Plan to, any other plan,
the terms of such merger, consolidation or transfer shall be such that each
Participant would receive (in the event of termination of this Plan or its
successor immediately thereafter) a benefit which 

<PAGE>

is no less than what the Participant would have received in the event of 
termination of this Plan immediately before such merger, consolidation or 
transfer.

14.6  INVESTMENT EXPERIENCE NOT A FORFEITURE.  The decrease in value of any
Account due to adverse investment experience shall not be considered an
impermissible "forfeiture" of any vested balance.


14.7  DISTRIBUTION TO LEGALLY INCAPACITATED.  In the event any benefit is
payable to a minor or to a person deemed to be incompetent or to a person
otherwise under legal disability, or who is by sole reason of advanced age,
illness, or other physical or mental incapacity incapable of handling the
disposition of his property, the Administrator, may direct the Trustee to apply
all or any portion of such benefit directly to the care, comfort, maintenance,
support, education or use of such person or to pay or distribute the whole or
any part of such benefit to (a) the spouse of such person, (b) the parent of
such person, (c) the guardian, committee, or other legal representative,
wherever appointed, of such person, (d) the person with whom such person shall
reside, (e) any other person having the care and control of such person, or
(f) such person.  The receipt of any such payment or distribution shall be a
complete discharge of liability for Plan obligations.


14.8  CONSTRUCTION.  Wherever appropriate, the use of the masculine gender shall
be extended to include the feminine and/or neuter or vice versa; and the
singular form of words shall be extended to include the plural; and the plural
shall be restricted to mean the singular.


14.9  GOVERNING DOCUMENTS.  A Participant's rights shall be determined under the
terms of the Plan as in effect at the Participant's date of separation from
Service.


14.10  GOVERNING LAW.  The provisions of this Plan shall be construed under the
laws of the state of the situs of the Trust, except to the extent such laws are
preempted by Federal law.


14.11  HEADINGS.  The Article headings and Section numbers are included solely
for ease of reference.  If there is any conflict between such headings or
numbers and the text of the Plan, the text shall control.


14.12  COUNTERPARTS.  This Plan may be executed in any number of counterparts,
each of which shall be deemed an original; said counterparts shall constitute
but one and the same instrument, which may be sufficiently evidenced by any one
counterpart.


14.13  LOCATION OF PARTICIPANT OR BENEFICIARY UNKNOWN.  In the event that all or
any portion of the distribution payable to a Participant or to a Participant's
Beneficiary hereunder shall, at the expiration of five (5) years after it shall
become payable, remain unpaid solely by reason of the inability of the
Administrator to ascertain the whereabouts of such Participant or Beneficiary,
after sending a registered letter, return receipt requested, to the last known
address, and after further diligent effort, the amount so distributable shall be
treated as a forfeiture under the Plan.  In the event a Participant or
Beneficiary is located subsequent to the reallocation of his Account balance,
such Account balance shall be restored in accordance with the provisions of
Section 6.2.

<PAGE>

                   ARTICLE FIFTEEN--MULTIPLE EMPLOYER PROVISIONS


15.1  ADOPTION OF THE PLAN.  With the consent of the board of directors of ODS
Networks, Inc., this Plan may be adopted by any other corporation or entity that
is not a member of the Employer's "related group" (as defined in Section 2.5)
for its employees, which adopting employer shall be known as a "Participating
Employer."  All assets may either be held within the Trust Fund, or each
Participating Employer may maintain a separate trust fund attributable to its
portion of Plan assets.  Separate accounting shall be maintained for the
Accounts of Employees of each adopting Participating Employer.


15.2  SERVICE.  For purposes of vesting, eligibility to participate in the Plan,
and determining eligibility for allocation of Participating Employer
contributions, an Employee shall be credited with all of his Hours of Service
with any Participating Employer which has adopted the Plan after the effective
date of that adoption.  Pre-adoption service will be credited in accordance with
the rules in Article Two for such periods of time when the Employees were part
of a controlled group of corporations, trades or businesses under common control
or affiliated service group.  These rules may be modified by an instrument of
adoption.


15.3  PLAN CONTRIBUTIONS.  All contributions made by a Participating Employer,
as provided for in this Plan and unless modified by an instrument of adoption,
shall be determined separately by each Participating Employer, and shall be paid
to and held by the Trustee for the exclusive benefit of the Employees of such
Participating Employer and the Beneficiaries of such Employees, subject to all
the terms and conditions of this Plan.  Any forfeiture by an Employee of a
Participating Employer subject to allocation during each Plan Year shall be
allocated only for the exclusive benefit of the Participants of such
Participating Employer in accordance with the provisions of this Plan, unless
modified by an instrument of adoption].


15.4  TRANSFERRING EMPLOYEES.  The Administrator shall adopt equitable
procedures whereby contributions and forfeitures are equitably allocated in the
case of Employees transferring from the employment of one Participating Employer
to another Participating Employer.  Similarly, rules shall be adopted whereby
Account records may be transferred from the records of one Participating
Employer to another Participating Employer.


15.5  DELEGATION OF AUTHORITY.  Each Participating Employer shall be deemed to
have appointed ODS Networks, Inc. as its agent to act on its behalf in all
matters relating to the administration, amendment, termination of the Plan and
the investment of the assets of the Plan.


15.6  TERMINATION.  Any termination of the Plan or discontinuance of
contributions by any one Participating Employer shall operate with regard only
to the Participants employed by that Participating Employer.  All Employees
affected thereby shall have a one hundred percent (100%) nonforfeitable interest
in their Accounts.

In the event any Participating Employer terminates its participation in this
Plan, or in the event that any such Participating Employer shall cease to exist
through sale, reorganization or bankruptcy, the Trust fund shall be allocated by
the Trustee, in accordance with the direction of the Administrator, into
separate Trust funds.  The amount to be allocated to the Trust of the
terminating Participating Employer shall be equal to the value of the Account
balances of its Participants as of the most recent date as of which Plan assets
were valued under Article Five, unless a special valuation is agreed to by the
Administrator and the terminating Participating Employer.

     set out in Section 4.1(c) and, as a result, the Participant is not eligible
     to make elective deferrals to the Plan for the balance of such Plan Year,
     if such Participant is employed by the Employer on the last day of such
     Plan Year, such Participant shall receive a supplemental matching
     contribution following the close of such Plan Year in an amount equal to
     the percentage (as determined by the Employer's board of directors for such
     Plan Year) of the Participant's Compensation contributed to the Plan as
     elective deferrals for such Plan Year, minus the amount of the Employer
     matching contribution previously made on behalf of such Participant for
     such Plan Year.

2.   Except as hereinabove amended, the provisions of the Plan shall continue in
     full force and effect.

Subject to the terms and conditions of this Loan Agreement, Bank agrees to
extend to Borrower, from the date hereof through the Termination Date (the
"AVAILABILITY PERIOD") a revolving line of credit which shall not exceed at any
one time outstanding $15,000,000.00 (the "REVOLVING CREDIT COMMITMENT").  Within

by a renewal promissory note made by Borrower, in the form attached hereto as
EXHIBIT "A" (together with any and all renewals, extensions for any period,

<PAGE>

obligation of Borrower to pay the lesser of: (i) the Revolving Credit 
Commitment or (ii) the aggregate unpaid principal amount of the Loan, with 
interest thereon as prescribed in the Note, which note is given in renewal 
and extension of a promissory note, dated April 12, 1997, in the original 
principal amount of $15,000,000 executed by Borrower and payable to the order 
of Bank.  The unpaid principal of the Note shall bear interest at a rate per 
annum which shall be equal to the lesser of (a) at the election of Borrower 
as specified in the request for an Advance given in accordance with SECTION 
2.3 below, (i) the Prime Rate as in effect from day to day, or (ii) the 
Eurodollar Rate plus one and three-quarters of one percent (1.75%), or (b) 
the Maximum Rate (as defined in the Note).  All past due principal of, and to 
the extent permitted by applicable law, interest on, the Note shall bear 
interest until paid at an annual rate equal to the lesser of (i) (a) for 
Prime Rate Advances, the Prime Rate from time to time in effect, plus two 
percent (2%), (b) for Eurodollar Advances, the Eurodollar Rate applicable to 
such Advances plus four percent (4%), or (ii) the Maximum Rate (such rate 
being referred to hereinafter as the "DEFAULT RATE").  The date and amount of 
each Advance made by Bank, and each payment of principal and interest, shall 
be maintained by Bank in its records, and the aggregate unpaid principal 
amount shown on such records shall be rebuttable presumptive evidence of the 
principal amount owing and unpaid on the Note.  The failure to record any 
such amount on such records shall not, however, limit or otherwise affect the 
obligations of Borrower hereunder or under the Note to repay the principal 
amount of the Advance together with all interest accruing thereon.

       2.3    PROCEDURE FOR ADVANCES.  Borrower shall give Bank prior verbal
notice on or before 12:00 noon (Dallas, Texas time) on any day a Prime Rate
Advance is requested.  Not later than 2:00 p.m., Dallas, Texas time, on the date
specified, subject to the terms and conditions of this Loan Agreement, Bank
shall make available to Borrower at Bank's offices in Dallas, Texas, the amount
of such requested Prime Rate Advance in immediately available funds.  Borrower
shall give Bank prior written notice on or before 12:00 noon (Dallas, Texas
time) at least two Eurodollar Business Days prior to the day a Eurodollar
Advance is requested.  The notice shall specify the requested amount of the
Advance, the duration of the Interest Period applicable to the Advance, and the
requested date of the Advance, which shall be a Eurodollar Business Day.  Not
later than 2:00 p.m., Dallas, Texas time, on the date specified, subject to the
terms and conditions of this Loan Agreement, Bank shall make available to
Borrower at Bank's offices in Dallas, Texas, the amount of such requested
Eurodollar Advance in immediately available funds.  Notice of a requested
Eurodollar Advance shall be irrevocable upon receipt thereof by Bank.

       2.4    COMMITMENT FEES.  Borrower agrees to pay Bank a commitment fee of
two-tenths of one percent (0.20%) per annum on the daily unused portion of the
Revolving Credit Commitment.  Such commitment fee shall be payable quarterly in
arrears on the last day of each June, September, December and March, commencing
March 31, 1998 (which payment shall cover the period from January 1, 1998
through March 31, 1998), and continuing regularly thereafter so long as the
Revolving Credit Commitment is in effect, and shall also be payable at the
maturity of the Note and upon the date of prepayment in full of the Note if the
Revolving Credit Commitment is thereupon terminated.  Borrower acknowledges and
agrees that the commitment fees payable hereunder are bona fide commitment fees
and are intended as reasonable compensation to Bank for committing to make funds
available to Borrower as described herein and for no other purpose.

       2.5    LETTERS OF CREDIT.  At the request of Borrower, and upon execution
of letter of credit documentation satisfactory to Bank (including, without
limitation, an Application and Agreement for Commercial Letter of Credit [for
documentary letters of credit] or Standby Letter of Credit Application and
Agreement [for standby letters of credit] for each such letter of credit in the
form attached hereto as EXHIBIT "D") (the "APPLICATION"), Bank shall issue
documentary or standby letters of credit ("LETTERS OF CREDIT") from time to time
for the account of Borrower in a face amount not exceeding in the aggregate at
any time outstanding the lesser of (a) $5,000,000, or (b) $15,000,000 MINUS the
aggregate outstanding principal balance of all Advances.  The Revolving Credit
Commitment shall at all times be reduced by the aggregate face amount of
outstanding Letters of Credit.  The Letters of Credit shall be on terms mutually
acceptable to Bank and Borrower and no Letter of Credit shall have an expiration
date later than one hundred eighty days after the Termination Date.  Any amount
paid by Bank on any Letter of Credit which is not immediately reimbursed by
Borrower shall be treated as an Advance without the necessity for any request by
Borrower.  Borrower shall pay to Bank, at the time of issuance of each
documentary Letter of Credit, a fee equal to one and one-quarter of one percent
(1.25%) per annum times the face amount of the Letter of Credit for the period
the Letter of Credit is to be outstanding.  Borrower shall pay to Bank, at the
time of issuance of each standby Letter of Credit, a fee equal to two percent
(2%) per annum times the face amount of the Letter of Credit for the period the
Letter of Credit is to be outstanding.  In connection with the issuance of any
Letters of Credit, Borrower shall pay to Bank its standard fees and charges,
including the standard fees and charges provided for

in the Application.  The obligations and indebtedness of Borrower to Bank 
under this SECTION 2.5, the Letters of Credit, and the Applications, shall be 
part of the Obligations.

       2.6    EURODOLLAR ADVANCES: CONVERSION, ROLLOVER, MINIMUM AMOUNTS, ETC.

                     (a)    CONVERSION FROM PRIME RATE ADVANCES.  Provided that
              no Event of Default shall have occurred and be continuing, upon
              three (3) Eurodollar Business Days' prior written notice from
              Borrower to Bank specifying the commencement date and length of
              the applicable Interest Period selected by Borrower, Borrower may
              convert an amount equal to $500,000 or an integral multiple of
              $50,000 in excess thereof, of any outstanding Prime Rate Advance
              into a Eurodollar Advance.

                     (b)    CONVERSION FROM EURODOLLAR ADVANCES.  Unless Bank
              shall have actually received written notice from Borrower
              requesting otherwise, delivered in accordance with SECTION 2.6(c)
              below, at least three (3) Eurodollar Business Days prior to the
              Final Interest Payment Date with respect to a Eurodollar Advance,
              then on such Final Interest Payment Date the outstanding
              Eurodollar Advance shall be converted to a Prime Rate Advance.

                     (c)    ROLLOVER.  Provided that no Event of Default shall
              have occurred and be continuing, at least three (3) Eurodollar
              Business Days prior to the Final Interest Payment Date of each
              Eurodollar Advance, Borrower may give to Bank written notice that
              all or any portion of such Eurodollar Advance shall continue as a
              Eurodollar Advance upon the expiration of the then-current
              Interest Period (the "ROLLOVER NOTICE").  Such Rollover Notice
              shall also specify the length of the succeeding Interest Period
              selected by Borrower with respect thereto.  Each Rollover Notice
              shall be effective and irrevocable upon receipt thereof by Bank. 
              If the required Rollover Notice shall not have been timely
              received by Bank, then Borrower shall be deemed to have elected to
              have such Eurodollar Advance be a Prime Rate Advance as provided
              in SECTION 2.6(b).

                     (d)    MINIMUM AMOUNTS AND NUMBER OF EURODOLLAR ADVANCES. 
              Notwithstanding any provision to the contrary contained herein,
              (i) each Eurodollar Advance shall be in an amount equal to
              $500,000, or an integral multiple of $50,000 in excess thereof,
              and (ii) there shall not exist or be outstanding at any time more
              than an aggregate of five (5) Eurodollar Advances.

                     (e)    LENDING OFFICE.  Bank may cause any Eurodollar
              Advance to be made by its principal office or by a foreign or
              domestic subsidiary, affiliate, branch or correspondent. 
              Notwithstanding the right of Bank to fund all or any portion of a
              Eurodollar Advance in any manner that it deems appropriate, Bank
              shall, regardless of the actual means of funding, be deemed to
              have funded the Eurodollar Advance in accordance with the interest
              option from time to time selected by Borrower.

       2.7    PROTECTION OF YIELD.

                     (a)    INCREASED COSTS, ETC.  Subject to SECTION 9.8, if at
              any time, and from time to time, Bank determines that the
              adoption, modification or implementation of, or compliance with,
              any applicable law, rule or regulation regarding taxation,
              required levels of reserves, deposits, insurance or capital
              (including any allocation of capital requirements or conditions),
              or similar requirements applicable to Bank, or any interpretation
              or administration thereof by any governmental authority, central
              bank or comparable agency charged with the interpretation,
              administration or compliance of or with any of such requirements,
              has or would have the effect of (i) increasing Bank's costs
              relating to the Loan, the Revolving Credit Commitment, or any part
              thereof or (ii) reducing the yield or rate of return of Bank on
              the Loan, the Revolving Credit Commitment, or any part thereof, to
              a level below that which Bank could have achieved but for the
              adoption, modification or implementation of, or compliance with,
              any such requirements, Borrower shall, within ten (10) days after
              any request by Bank, pay to Bank such additional amounts as (in
              Bank's sole judgment, after good faith and reasonable computation)
              will compensate Bank for such increase in costs or reduction in
              yield or rate of return of Bank.  No failure by Bank to demand
              immediately payment of any additional amounts payable under this
              SECTION 2.7(a) shall constitute a waiver of Bank's right to demand
              payment of such amounts at any subsequent time.  If Bank requests
              that Borrower pay additional amounts pursuant to this SECTION
              2.7(a), Bank shall submit to Borrower a certificate, executed by
              Bank, as to such additional amounts, which certificate shall be
              conclusive in the absence of manifest error.  Such certificate
              shall set forth the nature of the occurrence giving rise to such
              claim for additional amounts, the additional amounts to be paid to
              Bank hereunder, and the method by which such amounts were
              determined.  In determining such amounts, Bank may use any
              reasonable averaging and attribution methods.  Any portion of the
              additional amounts required to be paid under this SECTION 2.7(a)
              remaining unpaid ten (10) days after the due date thereof shall
              bear interest at the Default Rate.

                     (b)    SUBSTITUTE INTEREST RATE.  If, on or before any date
              on which a Eurodollar Rate is to be determined hereunder, Bank
              determines that deposits of United States Dollars in the
              appropriate amount for the appropriate period are not being
              offered in the interbank Eurodollar market for United States
              Dollars, or that by reason of circumstances affecting such market,
              adequate and reasonable means do not exist for ascertaining the
              Eurodollar Rate, then Bank shall promptly give notice of such
              determination to Borrower and such determination shall be
              conclusive and binding.  During the ten (10) days next following
              the giving of such notice, Borrower and Bank shall negotiate in
              good faith in order to arrive at a mutually satisfactory
              alternative interest rate (the "SUBSTITUTE RATE") to replace the
              rate otherwise applicable to the pertinent Eurodollar Advances of
              Borrower during the applicable Interest Period.  If, within such
              ten (10) day period, Borrower and Bank agree in writing upon a
              Substitute Rate, such rate shall be effective from the first day
              of such Interest Period.  If Bank and Borrower fail to agree upon
              a Substitute Rate within such ten (10) day period, the Substitute
              Rate applicable to the pertinent Eurodollar Advance during such
              Interest Period shall be the interest rate applicable to a Prime
              Rate Advance under SECTION 2.2.  Bank shall inform Borrower of
              such rate as promptly as practicable, and, if requested by
              Borrower, Bank shall deliver to Borrower a statement reflecting
              the computations made in determining such Substitute Rate.

                     (c)    CHANGES IN LAW RENDERING LOAN UNLAWFUL.  In the
              event that (i) any change in applicable law, treaty or regulation
              or the interpretation thereof (whether or not having the force of
              law) shall make it unlawful or impossible for Bank to make or
              continue to maintain all or any portion of a Eurodollar Advance
              contemplated hereunder, or (ii) any central bank or other fiscal,
              monetary or other authority having jurisdiction over Bank or all
              or any portion of a Eurodollar Advance shall request Bank in
              writing to comply with restrictions (whether or not having the
              force of law) which seek to prohibit Bank from making or
              continuing to maintain such a Eurodollar Advance, then Bank shall
              so notify Borrower, and Borrower shall, upon demand by Bank,
              either, at the option of Borrower, prepay such Eurodollar Advance
              or convert such Eurodollar Advance to a Prime Rate Advance in
              accordance with SECTION 2.6(b) hereof, except that, subject to the
              provisions of SECTION 2.7 hereof, such prepayment or conversion
              need not be effected on a Final Interest Payment Date, and upon
              such demand or upon notice by Bank, the obligation of Bank to make
              such Eurodollar Advance hereunder shall terminate.  Failure to
              prepay any 

<PAGE>

              such portion of a Eurodollar Advance shall be deemed an
              election to convert to a Prime Rate Advance.  Such demand or
              notice shall be accompanied by a certificate of Bank provided to
              Borrower as to the reasons why it is no longer feasible for Bank
              to make or continue to maintain such Eurodollar Advance hereunder
              and such certificate shall, in the absence of manifest error in
              calculation, be conclusive and binding.

                     (d)    EURODOLLAR CONSEQUENTIAL LOSS.  Borrower agrees to
              indemnify and hold harmless Bank from and against any Eurodollar
              Consequential Loss.  Borrower shall pay, within five (5) Business
              Days following demand therefor, the amount of any Eurodollar
              Consequential Loss incurred by Bank.  

                     (e)    REASONABLE EFFORTS.  Borrower and Bank will use all
              reasonable efforts to avoid or to minimize the obligation of
              Borrower to pay any amounts under this SECTION 2.7 or the
              subjecting of any payment by Borrower to any withholding tax, and
              Borrower will, as promptly as practical, notify Bank, and Bank
              will, as promptly as practicable, notify Borrower, of the
              existence of any event which will require the payment by Borrower
              of any such amounts or the subjecting of any payment by Borrower
              to any withholding tax; PROVIDED, HOWEVER, that any failure to
              give such prompt notification shall not in any way affect the
              rights of Bank or the obligations of Borrower hereunder.

                                     SECTION 3
                                          
                      PAYMENTS; COMPUTATIONS; USE OF PROCEEDS

       3.1    OPTIONAL PREPAYMENTS.  Borrower shall have the right, from time to
time, to prepay the Note, in whole or in part, without premium or penalty, upon
the payment of accrued interest on the amount prepaid to and including the date
of payment.  Prepayments of the Note shall not reduce the Revolving Credit
Commitment.

       3.2    PAYMENTS.  Principal and interest shall be due and payable as
provided in the Note and this Loan Agreement.  All payments (including
prepayments) by Borrower on account of principal, interest, and fees hereunder
shall be made in immediately available funds.  All such payments shall be made
to Bank at its principal office in Dallas, not later than 12:00 noon, Dallas,
Texas time, on the date due and funds received after that hour shall be deemed
to have been received by Bank on the next following Business Day.  If any
payment is scheduled to become due and payable on a day which is not a Business
Day, such payment shall instead become due and payable on the immediately
following Business Day and interest thereon shall be payable at the then
applicable rate during such extension.

       3.3    COMPUTATION OF INTEREST AND FEES.  Interest on the Note and the
fees shall be calculated on the basis of a year of 360 days, as the case may be,
for the actual number of days (including the first but excluding the last)
elapsed.  Any change in the interest rate on the Note resulting from a change in
the Prime Rate shall become effective as of the opening of business on the day
on which such change in the Prime Rate becomes effective.

       3.4    USE OF PROCEEDS.  Borrower represents, warrants and covenants that
it is not engaged and shall not engage in the business of extending credit for
the purposes of "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulations G, T, U or X
of the Board of Governors of the Federal Reserve System, and no part of the
proceeds of the Loan shall be used to purchase or carry any such margin stock or
to reduce or retire any indebtedness incurred for any such purposes.  If
requested by Bank, Borrower will furnish to Bank a statement in conformity with
the requirements of the Federal Reserve Form U-1 referred to in said Regulation
U to the foregoing effect.  No part of the proceeds of the Loan will be used for
any purpose which violates, or which is inconsistent with, the provisions of
Regulation X of said Board of Governors.  Portions of the Loan will be advanced
from time to time by Borrower to one or more of its Subsidiaries.

       4.3    EFFECT OF REQUEST FOR ANY SUBSEQUENT ADVANCE.  Any request by

                                     SECTION 5
                                          
                           REPRESENTATIONS AND WARRANTIES

       In order to induce Bank to enter into this Loan Agreement and to make the

affecting creditors' rights generally or general equitable principles),

       5.3    NO CONFLICTS.  The execution, delivery and performance by Borrower
of the Note and the other Loan Papers to which it is a party are not and will

agreement or other undertaking or instrument.

       5.4    NO CONSENTS.  The execution, delivery and performance by Borrower

<PAGE>

       5.6    LITIGATION.  There is no action, suit, investigation or proceeding
by or before any court, arbitrator, administrative agency or other governmental
authority pending or threatened (a) which involves any of the transactions
contemplated presently by this Loan Agreement which, if adversely determined,

       Bank the rights, interests, remedies, powers or privileges intended to be
       created thereby;

              (f)    Borrower or any Subsidiary shall generally not pay its
       debts as they become due or shall admit in writing its inability to pay

       reorganization or relief of debtors, or seeking appointment of a
       receiver, trustee, custodian or other similar official of it or him or of
       all or any substantial part of its or his property;

              (h)    Any case, proceeding or other action against Borrower or

       such Indebtedness for borrowed money or any agreement securing or
       relating to such Indebtedness (or any other material breach or material
       default under such indebtedness or agreement occurs) if the effect of
       such failure to perform or observe such provision (or breach or default)

       or prior to its regularly scheduled dates of payment and such failure
       continues for a period of thirty (30) days.

       8.2    DEFAULT REMEDIES.  If an Event of Default shall have occurred,

intention to accelerate, notice of acceleration, notice of default or other
notice of any kind, all of which hereby are expressly waived, (b) terminate the
Revolving Credit Commitment, (c) reduce any claim to judgment and/or (iv)
without notice of default or demand, pursue and enforce any of Bank's rights and
remedies under the Loan Papers, or otherwise provided under or pursuant to any
applicable law or agreement; provided, however, that if an Event of Default
specified in SECTION 8.1(g) or (h) above occurs, the Revolving Credit Commitment
shall be immediately terminated and the Note shall become immediately due and
payable, both as to principal and interest, without any action by Bank and
without presentment, demand, protest, notice of protest and nonpayment, notice
of intention to accelerate, notice of acceleration, notice of default or any
other notice of any kind or character, all of which are hereby expressly waived;
anything contained herein or in the Note to the contrary notwithstanding.  If
Borrower fails to pay when due the principal of, or interest on, the Note,
Borrower shall pay to the holder of such Note, to the extent permitted by
applicable law, such further amount as shall be sufficient to cover the cost and
expense of collection, including (but not limited to) reasonable attorneys'
fees.  Bank shall be entitled to exercise any and all rights and remedies
granted to it herein and in any of the other Loan Papers and under applicable
law.

deemed to be given when sent by mail, return receipt requested, postage prepaid,
and addressed to Bank at the address set forth opposite Bank's signature line or
at such other address as Bank may designate by written notice to Borrower.

       9.4    SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  All representations
and warranties made in the Note and in the other Loan Papers, including this
Loan Agreement, and in any certificates delivered pursuant hereto and thereto
shall survive the execution and delivery of this Loan Agreement and the Notes
and the making of the Loans.

       9.5    SUCCESSORS AND ASSIGNS.  This Loan Agreement shall be binding upon
and inure to the benefit of Borrower and Bank and their respective successors
and assigns, except that Borrower may not assign or transfer any of its rights
under this Loan Agreement without the prior written consent of Bank.

       9.6    COUNTERPARTS.  This Loan Agreement may be executed in any number
of separate counterparts and all of the said counterparts taken together shall
be deemed to constitute one and the same instrument.

       9.7    GOVERNING LAW.  THE NOTE AND THE OTHER LOAN PAPERS, INCLUDING THIS
LOAN AGREEMENT, SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS AND APPLICABLE FEDERAL LAWS, AND
SHALL BE PERFORMABLE IN DALLAS, DALLAS COUNTY, TEXAS.

       9.8    USURY.  It is the intention of the parties hereto to conform
strictly to usury laws applicable to Bank.  Accordingly, if the transactions
contemplated hereby would be usurious under applicable law (including the laws
of the United States of America and the State of Texas or any other jurisdiction
whose laws may be mandatorily applicable, notwithstanding the other provisions
of this Loan Agreement), then, in that event, notwithstanding anything to the
contrary in the Note, this Loan Agreement or in any other Loan Paper or
agreement entered into in connection with or as security for the Note, it is
agreed as follows: (i) the aggregate of all consideration which constitutes
interest under law applicable to Bank that is contracted for, taken, reserved,
charged or received under the Note, this Loan Agreement or under any of the
other aforesaid Loan Papers or agreements or otherwise in connection with the
Note, shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be credited by Bank on the principal amount
of the Obligation (or, if the principal amount of the Obligation shall have been
paid in full, refunded to Borrower); and (ii) in the event that the maturity of
any or all Note is accelerated by reason of an election of Bank resulting from
any Event of Default under this Loan Agreement or otherwise, or in the event of
any required or permitted prepayment, then such 

<PAGE>

consideration that constitutes interest under law applicable to Bank may 
never include more than the maximum amount allowed by such applicable law, 
and excess interest, if any, provided for in this Loan Agreement or otherwise 
shall be canceled automatically as of the date of such acceleration or 
prepayment and, if theretofore paid, shall be credited by Bank on the 
principal amount of the Obligation (or, if the principal amount of the 
Indebtedness shall have been paid in full, refunded by Bank to Borrower).  To 
the extent that Article 5069-1.04, as amended, of the Texas Revised Civil 
Statutes is relevant to Bank for the purpose of determining the maximum 
lawful rate, Bank hereby elects to determine the applicable rate ceiling 
under such Article by the indicated (weekly) rate ceiling from time to time 
in effect, subject to Bank's right subsequently to change such method in 
accordance with applicable law.

       9.9    NON-APPLICABILITY OF CHAPTER 346 OF THE TEXAS FINANCE CODE.  The
provisions of Chapter 346 of the Texas Finance Code shall not apply to the Loan
or any of the Loan Papers.

       9.10   DESCRIPTIVE HEADINGS.  The captions in this Loan Agreement are for
convenience of reference only and shall not define or limit the provisions
hereof.

       9.11   TERM OF LOAN AGREEMENT.  This Loan Agreement shall continue until
the Note shall have been paid in full and until all other liabilities and
obligations of Borrower under this Loan Agreement shall have been fully
satisfied and the Revolving Credit Commitment and all Letters of Credit
terminated in full.

       9.12   CAPITAL ADEQUACY.  If, after the date hereof, Bank shall have
determined that either (i) the adoption of any applicable law, rule, regulation
or guideline regarding capital adequacy, or any change therein, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, of (ii) compliance by Bank (or any lending office of
Bank) with any request or directive regarding capital adequacy (whether or not
having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on Bank's
capital as a consequence of its obligations hereunder to a level below that
which bank could have achieved but for such adoption, change or compliance
(taking into consideration Bank's policies with respect to capital adequacy) by
an amount deemed by Bank to be material, then from time to time, within ten (10)
days after demand by Bank Borrower shall pay to Bank such additional amount of
amounts as will compensate Bank for such reduction.  Bank will promptly notify
Borrower of any event of which it has actual knowledge, occurring after the date
thereof, which will entitle Bank to compensation pursuant to this SECTION 9.12. 
A certificate of Bank claiming compensation under this SECTION 9.12 and setting
forth the additional amount of amounts to be paid to it hereunder, together with
the description of the manner in which such amounts have been calculated, shall
be conclusive in the absence of manifest error.  In determining such amount,
Bank may use any reasonable averaging and attribution methods.

       9.13   RENEWAL, EXTENSION, AMENDMENT AND RESTATEMENT.  This Loan
Agreement is entered into for purposes of amending and restating the Prior Loan
Agreement.  This Agreement shall not constitute a novation of all or any portion
of the Borrower's indebtedness or obligations evidenced by or arising under or
otherwise existing with respect to the Prior Loan Agreement or any instrument,
agreement or other documents executed or delivered in connection therewith
(herein collectively referred to as the "ORIGINAL LOAN PAPERS").  All
Indebtedness and Obligations that are owed to the Bank under the Prior Loan
Agreement or under any Original Loan Paper shall continue to exist in full force
and effect.  The Loan outstanding under the Prior Loan Agreement as of the date
hereof shall be deemed to be, and shall be, the initial outstanding Loan under
this Loan Agreement and shall be subject to this Loan Agreement. 

       9.14   NO ORAL AGREEMENTS.  THIS AGREEMENT AND THE OTHER LOAN PAPERS AS
WRITTEN REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

                               NINTH PROMISSORY NOTE

$15,000,000.00                  Dallas, Texas                 December 31, 1997


       FOR VALUE RECEIVED, the undersigned, ODS NETWORKS, INC., formerly known
as OPTICAL DATA SYSTEMS, INC., a Texas corporation ("Maker") hereby
unconditionally promises to pay to the order of NATIONSBANK OF TEXAS, N.A.,
formerly known as NCNB Texas National Bank ("Payee"), at 901 Main Street, Dallas
Texas, or at such other address given to Maker by Payee, the principal sum of
Fifteen Million and No/100 Dollars ($15,000,000.00), or so much thereof as may
be advanced prior to maturity, in lawful money of the United States of America,
together with interest (calculated on the basis of a 360 day year), on the
unpaid principal balance from day-to-day remaining, computed from the date of
advance until maturity at the rate per annum which shall from day-to-day be
equal to the lesser of (a) the Maximum Rate, or (b) at the election of the Maker
as provided in the Loan Agreement, as amended (as hereinafter defined), (i) the
Prime Rate (hereinafter defined) in effect from day-to-day, or (ii) the
Eurodollar Rate (as defined in the Loan Agreement, as amended) plus one and
three-quarters percent (1.75%).  If at any time and from time to time the rate
of interest calculated pursuant to item (b) above would exceed the Maximum Rate,
thereby causing the interest payable hereon to be limited to the Maximum Rate,
then any subsequent reduction in the rate specified in item (b) above shall not
reduce the rate of interest hereon below the Maximum Rate until the total amount
of interest accrued hereon from and after the date of the first advance
hereunder equals the amount of interest which would have accrued hereon if the
rate specified in item (b) above had at all times been in effect.

       The term "Maximum Rate," as used herein, shall mean, with respect to the
holder hereof, the maximum nonusurious interest rate, if any, that at any time,
or from time to time, may be contracted for, taken, reserved, charged, or
received on the indebtedness evidenced by this Note.  To the extent that Article
5069-1.04, Title 79, Texas Revised Civil Statutes, as amended, is relevant to
any holder of this Note for the purposes of determining the Maximum Rate, the
Payee hereby notifies Maker that the "applicable rate ceiling" shall be the
"indicated rate ceiling" referred to in Article 5069-1.04(a)(1) from time to
time in effect, as limited by Article 5069-1.04(b); provided, however, that to
the extent permitted by applicable law, Payee reserves the right to change the
"applicable rate ceiling" from time to time by further notice and disclosure to
Maker; and, provided further, that the "Maximum Rate" for purposes of this Note
shall not be limited to the applicable rate ceiling under Article 5069-1.04 if
federal laws or other state laws now or hereafter in effect and applicable to
this Note (and the interest contracted for, charged and collected hereunder)
shall permit a higher rate of interest.

       As used herein, the term "Prime Rate" means the variable rate of interest
established from time to time by Payee as its Prime Interest Rate or Base Rate,
each change in the rate charged hereunder to become effective, without notice to
Maker, on the effective date of each change in the Prime Rate.  Maker
acknowledges that Payee may, from time to time, extend credit to other borrowers
at rates of interest varying from, and having no relationship to, such Prime
Interest Rate or Base Rate.

       This Note has been executed and delivered pursuant to, and is subject to
certain terms and conditions set forth in, that certain Third Amended and
Restated Revolving Credit Loan Agreement (the "LOAN AGREEMENT") between Maker
and Payee, dated as of December 31, 1997, and is the "Note" referred to in the
Loan Agreement.  The Holder of this Note shall be entitled to the benefits
provided in the Loan Agreement.  Reference is made to the Loan Agreement for a
statement of (i) the obligation of Payee to advance funds hereunder, (ii) the
events upon which the maturity of this Note may be accelerated, and (iii)
Maker's right to cure certain events of default, if any, as more fully set forth
therein.

       The entire unpaid principal balance of this Note shall be due and payable
in full on April 12, 1999.  Accrued and unpaid interest on this Note shall be
due and payable on each Interest Payment Date (as defined in the Loan Agreement,
as amended) and on the Termination Date (as defined in the Loan Agreement).

       All past due principal and, to the extent permitted by applicable law,
interest upon this Note shall bear interest at the Default Rate (as defined in
the Loan Agreement).

       Maker and each surety, endorser, guarantor and other party ever liable
for payment of any sums of money payable on this Note, jointly and severally
waive presentment, protest, notice of protest and non-payment, or other notice
of default, notice of acceleration and intention to accelerate, and agree that
their liability under this Note shall not be affected by any renewal or
extension in the time of payment hereof, or any indulgences, or by any 

<PAGE>

release or change in any security for the payment of this Note, and hereby 
consent to any and all renewals, extensions, indulgences, releases or 
changes, regardless of the number of such renewals, extensions, indulgences, 
releases or changes.

       No waiver by Payee of any of its rights or remedies hereunder or under
any other document evidencing or securing this Note or otherwise shall be
considered a waiver of any other subsequent right or remedy of Payee; no delay
or omission in the exercise or enforcement by Payee of any rights or remedies
shall ever be construed as a waiver of any right or remedy of Payee; and no
exercise or enforcement of any such rights or remedies shall ever be held to
exhaust any right or remedy of Payee.

       Maker reserves the right to prepay the outstanding principal balance of
this Note, in whole or in part, at any time and from time to time (subject to
the provisions of the Loan Agreement, as amended, relating to the prepayment of
Eurodollar Advances), without premium or penalty.  Any such prepayment shall be
made together with payment of interest accrued on the amount of principal being
prepaid through the date of such prepayment, and shall be applied to the
installments of principal due hereunder in the inverse order of maturity.  Any
prepayment of a Eurodollar Advance may be made only on the terms contained in
the Loan Agreement (as amended).

       Regardless of any provision contained in this Note, the Loan Agreement or
any other document executed or delivered in connection therewith, Payee shall
never be deemed to have contracted for or be entitled to receive, collect or
apply as interest on this Note, any amount in excess of the Maximum Rate, and,
in the event that Payee ever receives, collects or applies as interest any such
excess, such amount which would be excessive interest shall be applied to the
reduction of the unpaid principal balance of this Note, and, if the principal
balance of this Note is paid in full, any remaining excess shall forthwith be
paid to Maker.  In determining whether or not the interest paid or payable under
any specific contingency exceeds the Maximum Rate, Maker and Payee shall, to the
maximum extent permitted under applicable law, (i) characterize any
non-principal payment (other than payments which are expressly designated as
interest payments hereunder) as an expense or fee rather than as interest, (ii)
exclude voluntary prepayments and the effect thereof, and (iii) spread the total
amount of interest throughout the entire contemplated term of this Note so that
the interest rate is uniform throughout such term; provided, that if this Note
is paid and performed in full prior to the end of the full contemplated term
hereof, and if the interest received for the actual period of existence thereof
exceeds the Maximum Rate, if any, Payee or any holder hereof shall refund to
Maker the amount of such excess, or credit the amount of such excess against the
aggregate unpaid principal balance of all advances made by the Payee or any
holder hereof under this Note at the time in question.

       This Note is being executed and delivered, and is intended to be
performed in the State of Texas.  Except to the extent that the laws of the
United States may apply to the terms hereof, the substantive laws of the State
of Texas shall govern the validity, construction, enforcement and interpretation
of this Note.  In the event of a dispute involving this Note or any other
instruments executed in connection herewith, the undersigned irrevocably agrees
that venue for such dispute shall lie in any court of competent jurisdiction in
Dallas County, Texas.

       This Note modifies in its entirety that certain Eighth Renewal Promissory
Note dated April 12, 1997, executed by Maker and payable to the order of Payee
in the original principal amount of $15,000,000.00, but does not extinguish the
indebtedness evidenced thereby.  The indebtedness evidenced hereby was
originally evidenced by that certain Promissory Note dated April 30, 1990,
executed by Maker and payable to the order of Payee in the original principal
amount of $10,000,000.00.

remedies hereunder with respect to any of the Collateral.  Without limiting the
generality of the foregoing, it shall upon reasonable request by the Secured
Party (a) execute and deliver to the Secured Party such financing statements as
the Secured Party may from time to time require; (b) deliver to the Secured

deems necessary to perfect and protect its and the Debtor's interests in such

jurisdiction where the warehouseman, bailee, consignee, agent, processor or
other third Person is located (including the filing of a financing statement in
the proper jurisdiction naming the applicable third Person as debtor and it as
secured party and notifying the third Person's secured lenders of its interest
in such Collateral before the third Person receives possession of the Collateral
in question). 

       Section 4.4  CORPORATE CHANGES.  It shall not change its name, identity,
or corporate structure in any manner that might make any financing statement
filed in connection with this Agreement seriously misleading or its United
States Federal Tax I.D. Number unless it shall have given the Secured Party
thirty (30) days prior written notice thereof and shall have taken all action
reasonably deemed necessary or desirable by the Secured Party to protect its
Liens with the perfection and priority thereof required by the Loan Documents.

the place where it keeps its books and records unless it shall have given the

Party's security interest in such Collateral with the priority required by the

respect of any portion of the Collateral, such warehouse receipt or receipt in
the nature thereof shall not be "negotiable" (as such term is used in Section
7.104 of the UCC) unless such warehouse receipt or receipt in the nature thereof
is delivered to the Secured Party.

       Debtor's expense, at any time, or from time to time, all acts and things
       which the Secured Party deems necessary to protect, preserve, maintain,
       or realize upon the Collateral and the Secured Party's security interest
       therein.

       THIS POWER OF ATTORNEY IS A POWER COUPLED WITH AN INTEREST AND SHALL BE
IRREVOCABLE UNTIL TERMINATION OF THIS AGREEMENT IN ACCORDANCE WITH SECTION 7.11.
The Secured Party shall be under no duty to exercise or withhold the exercise of
any of the rights, powers, privileges and options expressly or implicitly
granted to the Secured Party in this Agreement, and shall not be liable for any
failure to do so or any delay in doing so.  Neither the Secured Party nor any
Person designated by the Secured Party shall be liable for any act or omission
or for any error of judgment or any mistake of fact or law, except any of the
same resulting from its or their gross negligence or willful misconduct.  This
power of attorney is conferred on the Secured Party solely to protect, preserve,
maintain and realize upon its security interest in the Collateral.  The Secured
Party shall not be responsible for any decline in the value of the Collateral
and shall not be required to take any steps to preserve rights against prior
parties or to protect, preserve or maintain any Lien given to secure the
Collateral.

       Section 5.2  ASSIGNMENT BY THE SECURED PARTY.  The Secured Party may at
any time assign or otherwise transfer all or any portion of its rights and
obligations under this Agreement and the other Loan Documents (including,

permitted by, and upon the conditions contained in, the Credit Agreement, and
such Person shall thereupon become vested with all the benefits thereof granted
to the Secured Party herein or otherwise.

       Section 5.3  POSSESSION; REASONABLE CARE.  The Secured Party may, from
time to time, in its sole discretion, appoint one or more agents to hold
physical custody, for the account of the Secured Party, of any or all of the
Collateral that the Secured Party has a right to possess.  The Secured Party
shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the Collateral is accorded
treatment substantially equal to that which the Secured Party accords its own
property, it being understood that the Secured Party shall not have any
responsibility for (a) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Collateral, whether or not the Secured Party has or is deemed to have knowledge
of such matters, or (b) taking any necessary steps to preserve rights against
any parties with respect to any Collateral.

                                      DEFAULT

       Section 6.1  RIGHTS AND REMEDIES.  If an Event of Default shall have
occurred and be continuing, the Secured Party shall have the following rights
and remedies:


<PAGE>


              (i)    In addition to all other rights and remedies granted to the
       Secured Party in this Agreement or in any other Loan Document or by
       applicable law, the Secured Party shall have all of the rights and
       remedies of a secured party under the UCC (whether or not the UCC applies
       to the affected Collateral).  Without limiting the generality of the
       foregoing, the Secured Party may (A) without demand or notice to it,
       collect, receive or take possession of the Collateral or any part thereof
       and for that purpose the Secured Party may enter upon any premises on
       which the Collateral is located and remove the Collateral therefrom or
       render it inoperable, and/or (B) sell, lease or otherwise dispose of the
       Collateral, or any part thereof, in one or more parcels at public or
       private sale or sales, at the Secured Party's offices or elsewhere, for
       cash, on credit or for future delivery, and upon such other terms as the
       Secured Party may deem commercially reasonable or otherwise as may be
       permitted by law.  The Secured Party shall have the right at any public
       sale or sales, and, to the extent permitted by applicable law, at any
       private sale or sales, to bid (which bid may be, in whole or in part, in
       the form of cancellation of indebtedness) and become a purchaser of the
       Collateral or any part thereof free of any right or equity of redemption
       on the part of Debtor, which right or equity of redemption is hereby
       expressly waived and released by Debtor.  Upon the request of the Secured
       Party, Debtor shall assemble the Collateral and make it available to the
       Secured Party at any place designated by the Secured Party that is
       reasonably convenient to it and the Secured Party.  Debtor agrees that
       the Secured Party shall not be obligated to give more than ten (10) days
       prior written notice of the time and place of any public sale or of the
       time after which any private sale may take place and that such notice
       shall constitute reasonable notice of such matters.  The Secured Party
       shall not be obligated to make any sale of Collateral if it shall
       determine not to do so, regardless of the fact that notice of sale of
       Collateral may have been given.  The Secured Party may, without notice or
       publication, adjourn any public or private sale or cause the same to be
       adjourned from time to time by announcement at the time and place fixed
       for sale, and such sale may, without further notice, be made at the time
       and place to which the same was so adjourned.  Debtor shall be liable for
       all reasonable expenses of retaking, holding, preparing for sale or the
       like, and all reasonable attorneys' fees, legal expenses and other costs
       and expenses incurred by the Secured Party in connection with the
       collection of the Obligations and the enforcement of the Secured Party's
       rights under this Agreement.  Debtor shall remain liable for any
       deficiency if the Proceeds of any sale or other disposition of the
       Collateral applied to the Obligations are insufficient to pay the
       Obligations in full.  The Secured Party may apply the Collateral against
       the Obligations as provided in the Credit Agreement.  Debtor waives all
       rights of marshalling, valuation and appraisal in respect of the
       Collateral.  Any cash held by the Secured Party as Collateral and all
       cash proceeds received by the Secured Party in respect of any sale of,
       collection from or other realization upon all or any part of the
       Collateral may, in the discretion of the Secured Party, be held by the
       Secured Party as collateral for, and then or at any time thereafter
       applied in whole or in part by the Secured Party against, the Obligations
       in the order permitted by the Credit Agreement.  Any surplus of such cash
       or cash proceeds and interest accrued thereon, if any, held by the

       require payment of any amount under, or performance of any provision of,
       any of the Collateral and any and all voting rights and corporate powers
       in respect of the Collateral.  Debtor shall execute and deliver (or cause
       to be executed and delivered) to the Secured Party all such proxies and
       other instruments as the Secured Party may reasonably request for the
       purpose of enabling the Secured Party to exercise the voting and other
       rights which it is entitled to exercise pursuant to this clause (iii) and
       to receive the dividends, interest and other distributions which it is
       entitled to receive hereunder.

              (iv)   The Secured Party may collect or receive all money or
       property at any time payable or receivable on account of or in exchange
       for any of the Collateral, but shall be under no obligation to do so.

              (v)    On any sale of the Collateral, the Secured Party is hereby
       authorized to comply with any limitation or restriction with which
       compliance is necessary, in the view of the Secured Party's counsel, in
       order to avoid any violation of applicable law or in order to obtain any
       required approval of the purchaser or purchasers by any applicable
       Governmental Authority.

                                 SECURITY INTEREST

       Section 2.1  SECURITY INTEREST.  As collateral security for the prompt
payment and performance in full when due of its Obligations (whether at stated
maturity, by acceleration or otherwise), each Debtor hereby pledges and assigns
to the Secured Party, and grants to the Secured Party a continuing lien on and
security interest in, all of the Debtor's right, title and interest in and to
the following, whether now owned or hereafter arising or acquired and wherever
located (collectively with respect to any Debtor or all Debtors, as the context
requires, the "COLLATERAL"):

       .6     all Accounts;

       .7     all Instruments, including, without limitation, or in addition,
       all instruments evidencing indebtedness from time to time owed to the
       Debtor by the Subsidiaries of the Debtor, and all interest, cash and

       Section 2.2  LIMITATION OF OBLIGATIONS SECURED.  Notwithstanding anything
to the contrary contained in this Agreement, the secured Obligations of each
Debtor hereunder shall not exceed an aggregate amount equal to the greatest
amount that would not render such Debtor's indebtedness, liabilities or
obligations under this Agreement subject to avoidance under Sections 544, 548 or
550 of the Federal Bankruptcy Code or subject to being set aside or annulled
under any applicable state law relating to fraud on creditors; PROVIDED,
HOWEVER, that, for purposes of the immediately preceding clause, it shall be
presumed that the secured Obligations of each Debtor under this Agreement do not
equal or exceed any aggregate amount which would render such Debtor's
indebtedness, liabilities or obligations under this Agreement subject to being
so avoided, set aside or annulled, and the burden of proof to the contrary shall
be on the party asserting to the contrary.  Subject to, but without limiting the
generality of, the foregoing sentence, the provisions of this Agreement are
severable and, in any legally binding action or proceeding involving any state
corporate law or any bankruptcy, insolvency or other laws of general application
relating to the enforcement of creditors' rights and general principles of
equity, if the indebtedness, liabilities or obligations of any Debtor under this
Agreement would otherwise be held or determined to be void, invalid or
unenforceable on account of the amount of its indebtedness, liabilities or
obligations under this Agreement, then, notwithstanding any other provisions of
this Agreement to the contrary, the amount of such indebtedness, liabilities or
obligations shall, without any further action by such Debtor, Secured Party or
any other Person, be automatically limited and reduced to the greatest amount
which is valid and enforceable as determined in such action or proceeding.

       Section 2.3  DEBTOR REMAINS LIABLE.  Notwithstanding anything to the
contrary contained herein, (a) each Debtor shall remain liable under the
documentation included in the Collateral to the extent set forth therein to
perform all of its duties and obligations thereunder to the same extent as if
this Agreement had not been executed, (b) the exercise by the Secured Party of
any of its rights or remedies hereunder shall not release any Debtor from any of
its duties or obligations under such documentation, (c) the Secured Party shall
not have any obligation under any of such documentation included in 

<PAGE>

the Collateral by reason of this Agreement, and (d) the Secured Party shall 
not be obligated to perform any of the obligations of any Debtor thereunder 
or to take any action to collect or enforce any claim for payment assigned 
hereunder.

                                     ARTICLE 3
                                          
                           REPRESENTATIONS AND WARRANTIES

       To induce the Secured Party to enter into this Agreement and the Credit
Agreement, each Debtor, with respect to itself and the Collateral in which it
has rights, represents and warrants to the Secured Party that:

                                     COVENANTS

       Each Debtor covenants and agrees with the Secured Party that until its
Obligations are paid and performed in full, all commitments of the Secured Party
under the Credit Agreement have expired or have been terminated and no Letter of
Credit remains outstanding:

       Section 4.1  ACCOUNTS. It shall, in accordance with its customary
business practices, endeavor to collect or cause to be collected from each
account debtor under its Accounts, as and when due, any and all amounts owing
under such Accounts.  Without the prior written consent of the Secured Party, it
shall not, except in the ordinary course of business and in no event when an
Event of Default exists, (a) grant any extension of time for any payment with
respect to any of its Accounts beyond 120 days after such payment's due date,
(b) compromise, compound, or settle any of its Accounts for less than the full
amount thereof, (c) release, in whole or in part, any Person liable for payment
of any of its Accounts, (d) allow any credit or discount for payment with
respect to any of its Accounts other than trade or other customary discounts
granted in the ordinary course of business, or (e) release any Lien or guaranty
securing any of its Accounts unless the Account has been paid.

       Section 4.2  FURTHER ASSURANCES; EXCEPTIONS TO PERFECTION.  At any time
and from time to time, upon the request of the Secured Party, and at its sole
expense, it shall promptly execute and deliver all such further agreements,
documents and instruments and take such further action as the Secured Party may
reasonably deem necessary or appropriate to preserve and perfect its security
interest in the Collateral and carry out the provisions and purposes of this
Agreement or to enable the Secured Party to exercise and enforce its rights and
remedies hereunder with respect to any of the Collateral.  Without limiting the
generality of the foregoing, it shall upon reasonable request by the Secured
Party (a) execute and deliver to the 

<PAGE>

Secured Party such financing statements as the Secured Party may from time to 
time require; (b) deliver to the Secured Party all Collateral the possession 
of which is necessary to perfect the security interest therein, duly endorsed 
and/or accompanied by duly executed instruments of transfer or assignment, 
all in form and substance satisfactory to Secured Party; EXCEPT THAT, prior 
to the occurrence of a Default, a Debtor may (i) retain for collection, in 
the ordinary course of business, checks representing Proceeds of Accounts 
received in the ordinary course of business; (ii) retain any letters of 
credit received in the ordinary course of business; and (iii) retain any 
Documents received and further negotiated in the ordinary course of business; 
and (c) execute and deliver to the Secured Party such other agreements, 
documents and instruments as the Secured Party may reasonably require to 
perfect and maintain the validity, effectiveness and priority of the Liens 
intended to be created by the Loan Documents.

       Section 4.3  THIRD PARTIES IN POSSESSION OF COLLATERAL.  Debtor shall not
permit any third Person (including any warehouseman, bailee, agent, consignee or
processor) to hold any Collateral, unless it shall:  (i) notify such third
Person of the security interests created hereby; (ii) instruct such Person to
hold all such Collateral for Secured Party's account subject to Secured Party's
instructions; and (iii) take all other actions the Secured Party reasonably
deems necessary to perfect and protect its and the Debtor's interests in such
Collateral pursuant to the requirements of the UCC of the applicable
jurisdiction where the warehouseman, bailee, consignee, agent, processor or
other third Person is located (including the filing of a financing statement in
the proper jurisdiction naming the applicable third Person as debtor and it as
secured party and notifying the third Person's secured lenders of its interest
in such Collateral before the third Person receives possession of the Collateral
in question). 

       Section 4.4  CORPORATE CHANGES.  It shall not change its name, identity,
or corporate structure in any manner that might make any financing statement
filed in connection with this Agreement seriously misleading or its United
States Federal Tax I.D. Number unless it shall have given the Secured Party
thirty (30) days prior written notice thereof and shall have taken all action
reasonably deemed necessary or desirable by the Secured Party to protect its
Liens with the perfection and priority thereof required by the Loan Documents. 
It shall not change its principal place of business, chief executive office or
the place where it keeps its books and records unless it shall have given the
Secured Party thirty (30) days prior written notice thereof and shall have taken
all action deemed necessary or desirable by the Secured Party to cause its
security interest in the Collateral to be perfected with the priority required
by the Loan Documents.

Party's security interest in such Collateral with the priority required by the
Loan Documents shall have been taken.

       Section 4.6  WAREHOUSE RECEIPTS NON-NEGOTIABLE.  It agrees that if any
warehouse receipt or receipt in the nature of a warehouse receipt is issued in
respect of any portion of the Collateral, such warehouse receipt or receipt in
the nature thereof shall not be "negotiable" (as such term is used in Section
7.104 of the UCC) unless such warehouse receipt or receipt in the nature thereof
is delivered to the Secured Party.

       Section 5.1  POWER OF ATTORNEY.  EACH DEBTOR HEREBY IRREVOCABLY
CONSTITUTES AND APPOINTS THE SECURED PARTY AND ANY OFFICER OR AGENT THEREOF,
WITH FULL POWER OF SUBSTITUTION, AS ITS TRUE AND LAWFUL ATTORNEY-IN-FACT WITH
FULL IRREVOCABLE POWER AND AUTHORITY IN THE NAME OF SUCH DEBTOR OR IN ITS OWN
NAME, TO TAKE, WHEN A DEFAULT EXISTS, ANY AND ALL ACTIONS AND TO EXECUTE ANY AND

       for any payment under any of the Collateral to make payment of any and
       all monies due and to become due thereunder directly to the Secured Party
       or as the Secured Party shall direct (each Debtor agrees that if any
       Proceeds of any Collateral (including payments made in respect of
       Accounts) shall be received by it while a Default exists, it shall
       promptly deliver such Proceeds to the Secured Party with any necessary
       endorsements, and until such Proceeds are delivered to the Secured Party,
       such Proceeds shall be held in trust by it for the benefit of the Secured
       Party and shall not be commingled with any other funds or property of
       it); (B) to receive payment of and receipt for any and all monies, claims

       any committee, depositary, transfer agent, registrar or other designated
       agency upon such terms as the Secured Party may 

<PAGE>

       determine; (H) to add or release any guarantor, indorser, surety or 
       other party to any of the Collateral; (I) to renew, extend or 
       otherwise change the terms and conditions of any of the Collateral; 
       (J) to make, settle, compromise or adjust any claims under or 
       pertaining to any of the Collateral (including claims under any policy 
       of insurance); and (K) to sell, transfer, pledge, convey, make any

       option and the Debtors' expense, at any time, or from time to time, 
       all acts and things which the Secured Party deems necessary to 
       protect, preserve, maintain, or realize upon the Collateral and the 
       Secured Party's security interest therein.

       THIS POWER OF ATTORNEY IS A POWER COUPLED WITH AN INTEREST AND SHALL BE
IRREVOCABLE UNTIL TERMINATION OF THIS AGREEMENT IN ACCORDANCE WITH SECTION 7.11.
The Secured Party shall be under no duty to exercise or withhold the exercise of
any of the rights, powers, privileges and options expressly or implicitly
granted to the Secured Party in this Agreement, and shall not be liable for any
failure to do so or any delay in doing so.  Neither the Secured Party nor any
Person designated by the Secured Party shall be liable for any act or omission
or for any error of judgment or any mistake of fact or law, except any of the
same resulting from its or their gross negligence or willful misconduct.  This
power of attorney is conferred on the Secured Party solely to protect, preserve,
maintain and realize upon its security interest in the Collateral.  The Secured
Party shall not be responsible for any decline in the value of the Collateral
and shall not be required to take any steps to preserve rights against prior
parties or to protect, preserve or maintain any Lien given to secure the
Collateral.

       Section 5.2  ASSIGNMENT BY THE SECURED PARTY.  The Secured Party may at
any time assign or otherwise transfer all or any portion of its rights and
obligations under this Agreement and the other Loan Documents (including,
without limitation, the Obligations) to any other Person, to the extent
permitted by, and upon the conditions contained in, the Credit Agreement, and
such Person shall thereupon become vested with all the benefits thereof granted
to the Secured Party herein or otherwise.

       Section 5.3  POSSESSION; REASONABLE CARE.  The Secured Party may, from
time to time, in its sole discretion, appoint one or more agents to hold
physical custody, for the account of the Secured Party, of any or all of the
Collateral that the Secured Party has a right to possess.  The Secured Party
shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the Collateral is accorded
treatment substantially equal to that which the Secured Party accords its own
property, it being understood that the Secured Party shall not have any
responsibility for (a) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Collateral, whether or not the Secured Party has or is deemed to have knowledge
of such matters, or (b) taking any necessary steps to preserve rights against
any parties with respect to any Collateral.

                                      DEFAULT

       Section 6.1  RIGHTS AND REMEDIES.  If an Event of Default shall have
occurred and be continuing, the Secured Party shall have the following rights
and remedies:

              (i)    In addition to all other rights and remedies granted to the
       Secured Party in this Agreement or in any other Loan Document or by
       applicable law, the Secured Party shall have all of the rights and
       remedies of a secured party under the UCC (whether or not the UCC applies
       to the affected Collateral).  Without limiting the generality of the
       foregoing, the Secured Party may (A) without demand or notice to it,
       collect, receive or take possession of the Collateral or any part thereof
       and for that purpose the Secured Party may enter upon any premises on
       which the Collateral is located and remove the Collateral therefrom or
       render it inoperable, and/or (B) sell, lease or otherwise dispose of the
       Collateral, or any part thereof, in one or more parcels at public or
       private sale or sales, at the Secured Party's offices or elsewhere, for
       cash, on credit or for future delivery, and upon such other terms as the
       Secured Party may deem commercially reasonable or otherwise as may be
       permitted by law.  The Secured Party shall have the right at any public
       sale or sales, and, to the extent permitted by applicable law, at any
       private sale or sales, to bid (which bid may be, in whole or in part, in
       the form of cancellation of indebtedness) and become a purchaser of the
       Collateral or any part thereof free of any right or equity of redemption
       on the part of any Debtor, which right or equity of redemption is hereby
       expressly waived and released by each Debtor.  Upon the request of the
       Secured Party, each Debtor shall assemble its Collateral and make it
       available to the Secured Party at any place designated by the Secured
       Party that is reasonably convenient to it and the Secured Party.  Each
       Debtor agrees that the Secured Party shall not be obligated to give more
       than ten (10) days prior written notice of the time and place of any
       public sale or of the time after which any private sale may take place
       and that such notice shall constitute reasonable notice of such matters. 
       The Secured Party shall not be obligated to make any sale of Collateral
       if it shall determine not to do so, regardless of the fact that notice of
       sale of Collateral may have been given.  The Secured Party may, without
       notice or publication, adjourn any public or private sale or cause the
       same to be adjourned from time to time by announcement at the time and
       place fixed for sale, and such sale may, without further notice, be made
       at the time and place to which the same was so adjourned.  Each Debtor
       shall be liable for all reasonable expenses of retaking, holding,
       preparing for sale or the like, and all reasonable attorneys' fees, legal
       expenses and other costs and expenses incurred by the Secured Party in
       connection with the collection of the Obligations and the enforcement of
       the Secured Party's rights under this 

<PAGE>


       Agreement.  Each Debtor shall remain liable for any deficiency if the 
       Proceeds of any sale or other disposition of the Collateral applied to 
       the Obligations are insufficient to pay the Obligations in full.  The 
       Secured Party may apply the Collateral against the Obligations as 
       provided in the Credit Agreement. Each Debtor waives all rights of 
       marshalling, valuation and appraisal in respect of the Collateral.  
       Any cash held by the Secured Party as Collateral and all cash proceeds 
       received by the Secured Party in respect of any sale of, collection 
       from or other realization upon all or any part of the Collateral may, 
       in the discretion of the Secured Party, be held by the Secured Party 
       as collateral for, and then or at any time thereafter applied in whole 
       or in part by the Secured Party against, the Obligations in the order 
       permitted by the Credit Agreement.  Any surplus of such cash or cash 
       proceeds and interest accrued thereon, if any, held by the Secured 
       Party and remaining after payment in full of all the Obligations shall 
       be promptly paid over to the Debtor entitled thereto or to whomsoever 
       may be lawfully entitled to receive such surplus; PROVIDED THAT the 
       Secured Party shall have no obligation to invest or otherwise pay 
       interest on any amounts held by it in connection with or pursuant to 
       this Agreement.

              (ii)   The Secured Party may cause any or all of the Collateral
       held by it to be transferred into the name of the Secured Party or the
       name or names of the Secured Party's nominee or nominees.

              (iii)  The Secured Party may exercise any and all of the  rights
       and remedies of any Debtor under or in respect of the Collateral,
       including, without limitation, any and all rights of it to demand or
       otherwise require payment of any amount under, or performance of any
       provision of, any of the Collateral and any and all voting rights and
       corporate powers in respect of the Collateral.  Each Debtor shall execute
       and deliver (or cause to be executed and delivered) to the Secured Party
       all such proxies and other instruments as the Secured Party may
       reasonably request for the purpose of enabling the Secured Party to
       exercise the voting and other rights which it is entitled to exercise
       pursuant to this clause (iii) and to receive the dividends, interest and
       other distributions which it is entitled to receive hereunder.

              (iv)   The Secured Party may collect or receive all money or
       property at any time payable or receivable on account of or in exchange
       for any of the Collateral, but shall be under no obligation to do so.

              (v)    On any sale of the Collateral, the Secured Party is hereby
       authorized to comply with any limitation or restriction with which
       compliance is necessary, in the view of the Secured Party's counsel, in
       order to avoid any violation of applicable law or in order 

<PAGE>

       to obtain any required approval of the purchaser or purchasers by any 
       applicable Governmental Authority.

the Secured Party to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power or privilege under this Agreement
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege under this Agreement preclude any other or further
exercise thereof or the exercise of any other right, power, or privilege.  The
rights and remedies provided for in this Agreement are cumulative and not
exclusive of any rights and remedies provided by law.

       Section 7.2  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding

1997 COMPARED WITH 1996


                                     NET SALES

          Net sales in 1997 decreased to $92.3 million from $117.9 million in
     1996 as sales of the Company's new network switching products did not
     increase quickly enough to offset the decrease in sales of its prior
     generation shared bandwidth intelligent hubs.  Demand for prior generation
     shared bandwidth intelligent hubs may continue to decline as the market
     transitions to switching products with enhanced price/performance
     characteristics.
     
           Export sales in 1997 increased to $25.1 million, or 27.2% of net
     sales, compared to $17.1 million, or 14.4% of net sales in 1996 primarily
     due to growth in export sales to customers in Malaysia and South Korea. 
     Sales to customers in Malaysia and South Korea declined in the fourth
     quarter of 1997 compared to the preceding quarters in 1997 and may decrease
     in 1998 compared to 1997 due to the adverse economic developments in these
     countries.  
     
          Sales to Electronic Data Systems Corporation ("EDS") in 1997 and 1996
     were 16.1% and 19.4%, respectively, of net sales.  Sales to AT&T Corp.
     ("AT&T") in 1997 and 1996 were 1.6% and 12.1%, respectively, of net sales. 
     Direct net sales to various agencies of the U.S. Government (aggregated as
     one) were 11.7% and 13.5%, respectively, of net sales.  In addition, a
     portion of the Company's sales to EDS, AT&T and other corporations were
     resold by those organizations to various agencies of the U.S. Government.
     
     
                                    GROSS PROFIT

          Gross profit decreased to $36.5 million or 39.6% of net sales in 1997
     compared to $57.1 million or 48.5% of net sales in 1996.  Gross profit as a
     percentage of net sales in 1997 was impacted by several factors, including
     a decline in the net realizable value of certain prior generation products,
     an increase in reserves for slow-moving inventory of such prior generation
     products, product mix and lower sales volumes.  Gross profit margins in
     future periods may be affected by several factors such as continued product
     transition, declining market demand for prior generation products,
     obsolescence or surplus of inventory, shifts in product mix, changes in
     channels of distribution, sales volume, fluctuation in manufacturing costs,
     pricing strategies of the Company and its competitors and fluctuations in
     sales of integrated third-party products.  Gross profit margins are
     typically lower on sales of integrated third-party products.

                                SALES AND MARKETING

          Sales and marketing expenses increased to $30.4 million or 32.9% of
     net sales in 1997 from $26.0 million or 22.0% of net sales in 1996.  The
     increase in sales and marketing expenses was primarily due to higher levels
     of staffing in sales, marketing and technical support and associated costs.
     The Company expects sales and marketing expenses to continue to increase in
     amount, but may vary as a percentage of net sales in the future.  
     
     
                              RESEARCH AND DEVELOPMENT

          Research and development expenses increased to $10.8 million or 11.7%
     of net sales in 1997 compared to $10.4 million or 8.8% of net sales in
     1996. The Company's research and development costs are expensed in the
     period incurred.  The increase in research and development expenses was
     primarily due to an increase in the number of development personnel and
     increased costs related to the development and testing of switching
     products, network management products and network security products.  The
     Company expects to continue to invest in research and development
     activities in the future in an effort to broaden its family of network
     switching, management and security products.
                 
                             GENERAL AND ADMINISTRATIVE

          General and administrative expenses increased to $4.9 million or 5.3%
     of net sales in 1997 from $3.8 million or 3.3% of net sales in 1996.  As
     the Company continues to expand its domestic and foreign operations,
     general and administrative expenses are expected to increase in amount, but
     may vary as a percentage of net sales in the future.
            
                                NET INTEREST INCOME

          Net interest income increased to $1.6 million in 1997 compared to $0.9
     million in 1996 primarily due to an increase in the Company's average cash
     and investment balances during 1997.   Net interest income may vary in the
     future based on the Company's cash flow and rate of return on investments.
            
            
                                    INCOME TAXES

          The Company's effective income tax rate decreased to  37.8% in 1997
     compared to 38.1% in 1996. See Note 7 of Notes to Consolidated Financial
     Statements.

1996 COMPARED WITH 1995


                                      NET SALES
                         
          Net sales in 1996 increased by 5.8% to $117.9 million from $111.5
     million in 1995 as sales of the Infinity Intelligent Hub and InfiniteSwitch
     product line increased.  

          Export sales in 1996 increased to $17.1 million, or 14.4% of net
     sales, compared to $12.9 million , or 11.6% of net sales in 1995.  Export
     sales increased in 1996 as the Company increased its international sales
     and marketing efforts, especially in Asia.

          In 1996, 19.4% of net sales were to EDS compared to 28.3% of net sales
     in 1995; 13.5% of net sales in 1996 were to various agencies of the U.S.
     Government (aggregated as one), compared to 9.6% of net sales in 1995; and
     12.1% of net sales in 1996 were to AT&T  compared to 12.0% of net sales in
     1995.  

                                     GROSS PROFIT

          Gross profit increased to $57.1 million in 1996 compared to $56.0
     million in 1995 but decreased as a percentage of net sales to 48.5% in 1996
     from 50.2% in 1995.  Gross profit as a percentage of net sales was impacted
     during 1996 by an increase in reserves for slow-moving inventory, product
     mix and the market transition to higher performance switch products.  

                                 SALES AND MARKETING

          Sales and marketing expenses increased to $26.0 million or 22.0% of
     net sales in 1996 compared to $22.6 million or 20.2% of net sales in 1995. 
     The increase in sales and marketing expenses was primarily due to expansion
     of domestic and international sales and marketing personnel and associated 
     costs.

                               RESEARCH AND DEVELOPMENT

          Research and development expenses increased to $10.4 million or 8.8%
     of net sales in 1996 compared to $8.0 million or 7.2% of net sales in 1995.
     The increase in research and development expenses in 1996 was primarily due
     to an increase in the number of developmental personnel, additional product
     development expenses and increased costs related to the development and
     testing of new switching products.  

<PAGE>

                              GENERAL AND ADMINISTRATIVE

          General and administrative expenses decreased in amount to $3.8
     million in 1996 compared to $4.2 million in 1995 and declined as a
     percentage of net sales to 3.3% in 1996 from 3.8% in 1995.   


                                 NET INTEREST INCOME

          Net interest income remained constant at $0.9 million for both 1996
     and 1995.  


                                     INCOME TAXES

          The Company's effective tax rate remained unchanged at 38.1% for both
     1996 and 1995.  
                               
                          LIQUIDITY AND CAPITAL RESOURCES
          
          The Company's principal sources of liquidity at December 31, 1997 were
     $17.9 million of cash and cash equivalents, $14.7 million of short-term
     investments, $3.2 million of highly liquid investments with a stated
     maturity beyond one year and an available line of credit. As of December
     31, 1997, working capital was $51.8 million compared to $54.5 million as of
     December 31, 1996.

          Cash flows provided by operations in 1997 were $13.4 million,
     primarily due to a decrease in inventory and accounts receivable balances
     partially offset by a net loss for the year. Future fluctuations in
     accounts receivable and inventory balances will be dependent upon several
     factors, including but not limited to quarterly sales, ability to collect
     accounts receivable timely, the Company's strategy as to building inventory
     in advance of receiving orders from customers, and the accuracy of the
     Company's forecasts of product demand and component requirements.
           
          Cash used in investing activities in 1997 consisted of purchases of
     property and equipment of $3.4 million partially offset by net maturities
     of investments of $1.0 million.

          Cash provided by financing activities in 1997 was $0.6 million which
     consisted of the issuance of common stock relating to the exercise of
     certain warrants and employee stock options.  

          During 1997, the Company funded its operations solely through cash
     flow from operations.  The Company has a bank line of credit agreement with
     $15.0 million of maximum available borrowings.  Borrowings under 

<PAGE>

     this line are secured by the Company's accounts receivable and inventory 
     and are subject to certain limitations and conditions, including the 
     maintenance of certain financial ratios and minimum net tangible worth 
     amounts. Borrowings on this line accrue interest at prime with interest 
     due monthly and principal due April 12, 1999.  As of December 31, 1997, 
     the Company had no borrowings outstanding under its bank credit facility, 
     and had $15.0 million available for allowable borrowings at an applicable 
     interest rate of  8.5% per annum.  See Note 4 of Notes to Consolidated 
     Financial Statements.

          The Company believes that its cash, cash equivalents and investment
     balances and the availability of borrowings under its bank credit facility
     will provide sufficient cash resources to finance its operations and
     currently projected capital expenditures through 1998.  However, there can
     be no assurance the Company's cash resources will be sufficient for 1998 or
     future periods.



FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS   


     As noted above, the foregoing discussions may include forward-looking
     statements that involve risks and uncertainties.  In addition to those
     factors discussed elsewhere in this Annual Report and those discussed in
     the Company's Form 10-K and other filings with the Securities and Exchange
     Commission, the Company identifies the following factors which could affect
     the Company's actual results and cause actual results to differ materially
     from those in the forward-looking statements.

 
     TECHNOLOGICAL CHANGES.  The market for the Company's products is
     characterized by frequent product introductions, rapidly changing
     technology and continued evolution of new industry standards. The market
     for network intelligent hubs and switches requires the Company's products
     to be compatible and interoperable with products and architectures offered
     by various vendors, including other networking products, workstation and
     personal computer architectures and computer and network operating systems.
     The Company's success will depend to a substantial degree upon its ability
     to develop and introduce in a timely manner new products and enhancements
     to its existing products that meet changing customer requirements and
     evolving industry standards.  The development of 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 and support new or enhanced products
     successfully in a timely manner.  Further, the 


<PAGE>

     Company or its competitors may introduce new products or product 
     enhancements that shorten the life cycle of or obsolete the Company's 
     existing product lines which could have a material adverse effect on the 
     Company's business, operating results and financial condition.

     COMPETITION AND MARKET ACCEPTANCE.  The market for network intelligent hubs
     and switches is intensely competitive and subject to frequent product
     introductions with improved price/performance characteristics.  Even if the
     Company does introduce advanced products which meet evolving customer
     requirements in a timely manner, there can be no assurance that the new
     Company products will gain market acceptance.  Many networking companies,
     including Cisco Systems, Inc. ("Cisco"), Cabletron Systems, Inc.
     ("Cabletron"), Bay Networks, Inc. ("Bay Networks"), FORE Systems, Inc.
     ("FORE Systems"), Xylan Corporation ("Xylan")  and others, have
     substantially greater financial, technical, sales and marketing resources,
     better name recognition and a larger customer base than the Company.  Many
     of the Company's large competitors offer customers a broader product line
     which provides a more comprehensive networking solution than the Company
     currently offers.  The Company anticipates increased competition from large
     telecommunication equipment vendors which are expanding their capabilities
     in the data networking market.  For example, Lucent Technologies has
     acquired several networking companies to enhance its capabilities in data
     networking. Further the Company anticipates increased competition from
     private "start-up" companies that have developed or are developing advanced
     network switching products.  Increased competition in the networking
     industry 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. 

          The Company is pursuing a strategy to increase the percentage of its
     revenue generated through indirect sales channels including value added
     resellers, system integrators, original equipment manufacturers and network
     service providers.  There can be no assurance that the Company's products
     will gain market acceptance in these indirect sales channels.  Further,
     competition among networking companies to sell products through these
     indirect sales channels could result in significant price competition and
     reduced profit margins.  

          The Company is also pursuing a strategy to broaden and further
     differentiate its product line by introducing complementary network
     switching, management and security products and incorporating new
     technologies into its existing product line.  There can be no assurance
     that the Company will successfully introduce these products or that such
     products will gain market acceptance.  The Company anticipates competition
     from networking companies, network security companies and others in each of
     its product lines.  The Company anticipates that profit margins will vary
     among its product lines and that product mix fluctuations could have an
     adverse effect on the Company's overall profit margins. 
           

<PAGE>

     ACQUISITIONS. Cisco, Cabletron, Bay Networks, FORE Systems, Lucent
     Technologies and other competitors have recently acquired several
     networking companies with complementary technologies, and the Company
     anticipates that such acquisitions will continue in the future. These
     acquisitions may permit such competitors to accelerate the development and
     commercialization of broader product lines and more comprehensive
     networking solutions than the Company currently offers.  In the past, the
     Company has relied upon a combination of internal product development and
     partnerships with other networking vendors to provide competitive
     networking solutions to customers.  Certain of the recent and future
     acquisitions by the Company's competitors may have the effect of limiting
     the Company's access to commercially significant technologies.  Further,
     the business combinations and acquisitions in the networking industry are
     creating companies with larger market shares, customer bases, sales forces,
     product offerings and technology and marketing expertise.  There can be no
     assurance that the Company will be able to compete successfully in such an
     environment.

     The Company may, in the future, acquire or invest in another company,
     business unit, product line, or technology to accelerate the development of
     products and sales channels complementary to the Company's existing
     products and sales channels.  Acquisitions involve numerous risks,
     including difficulties in assimilation of operations,  technologies, and
     products of the acquired companies; risks of entering markets in which the
     Company has no or limited direct prior experience and where competitors in
     such markets have stronger market positions; the potential loss of key
     employees of the acquired company; and the diversion of management's
     attention from normal daily operation of the Company's business.

     PRODUCT TRANSITIONS.  Once current networking products have been in the
     market place for a period of time and begin to be replaced by higher
     performance products (whether of the Company's or a competitor's design),
     the Company expects the net sales of such networking products to decrease.
     In order to achieve revenue growth in the future, the Company will be
     required to design, develop and successfully commercialize higher
     performance products in a timely manner.  For example,  the market for
     shared bandwidth intelligent hubs, sales of which represented the  majority
     of the Company's net sales over the past several years,  decreased in 1997
     and may continue to decrease as switching products with enhanced
     price/performance characteristics gain market acceptance.  There can be no
     assurance that the Company will be able to introduce new products and gain
     market acceptance quickly enough to avoid adverse revenue transition
     patterns during current or future product transitions.
          
<PAGE>
          
          
     MANUFACTURING AND AVAILABILITY OF COMPONENTS.  The Company's manufacturing
     operations consist primarily of final assembly, testing and quality control
     of subassemblies and finished units.  Materials used by the Company in its
     manufacturing processes include semiconductors such as microprocessors,
     memory chips and application specific integrated circuits ("ASICs"),
     printed circuit boards, power supplies and enclosures.  All of the
     materials used in the Company's products are purchased under contracts and
     purchase orders with third parties.  While the Company believes that many
     of the materials used in the production of its products are generally
     readily available from a variety of sources, certain components are
     available from one or a limited number of suppliers.  For example, certain
     ASICs designed into the Company's InfiniteSwitch products are supplied by
     FORE Systems (see "Factors That May Affect Future Results of Operations -
     Competition and Market Acceptance").  The lead times for delivery of
     components vary significantly and exceed twelve weeks for certain
     components.  If the Company should fail to forecast its requirements
     accurately for components, it may experience excess inventory or shortages
     of certain components which could have an adverse effect on the Company's
     business and operating results.  Further, any interruption in the supply of
     any of these components, or the inability of the Company to procure these
     components from alternative sources at acceptable prices within a
     reasonable time, could have an adverse effect on the Company's business and
     operating results.


     THIRD-PARTY PRODUCTS.  The Company believes that it is beneficial to work
     with third parties with complementary technologies to broaden the appeal of
     the Company's switches, intelligent hub and network security products. 
     These alliances allow ODS to provide integrated solutions to its customers,
     combining ODS developed technology with third-party products such as
     certain routers from Cisco, ATM switches from FORE systems and Gigabit
     Ethernet switch technology from Lucent Technologies.  As the Company also
     competes with these technology partners in certain segments of the market,
     there can be no assurance that the Company will have access to all of the
     third-party products which may be desirable in  to offer fully integrated
     solutions to ODS customers.
          
          
     DEPENDENCE ON KEY CUSTOMERS.   A relatively small number of customers have
     accounted for a significant portion of the Company's revenue. U.S.
     Government agencies and strategic network integrators, such as EDS, which
     purchase the Company's products for internal use and offer the Company's
     products for resale, are expected to continue to account for a substantial
     portion of the Company's net revenue.  The Company continuously faces
     competition from Cisco, Cabletron, Bay Networks, FORE Systems, Xylan and
     others for U.S. Government networking projects and corporate networking
     installations.  Any reduction or delay in sales of the Company's 

<PAGE>

     products to these customers could have a material adverse effect on the 
     Company's operating results.

     INTERNATIONAL OPERATIONS.  Export sales accounted for approximately 27.2%
     of the Company's revenue in 1997.  The Company expects that export sales
     will represent a significant portion of its business in the future.  The
     Company's international operations may be affected by changes in demand
     resulting from fluctuations in currency exchange rates and local purchasing
     practices, including seasonal fluctuations in demand, as well as by risks
     such as increases in duty rates, difficulties in distribution and other
     constraints upon international trade.  For example, the fluctuations in
     currency exchange rates and adverse economic developments in Malaysia,
     South Korea and certain other countries adversely affected demand for the
     Company's products in those countries in the fourth quarter of 1997 and may
     continue to adversely affect demand for the Company's products in those
     countries in 1998.  Additionally, while the Company's current products are
     designed to meet relevant regulatory requirements of the foreign markets in
     which they are sold, any inability to obtain any required foreign
     regulatory approvals on a timely basis could have a material adverse effect
     on the Company's operating results. 

     INTELLECTUAL PROPERTY.  The Company's success and its ability to compete is
     dependent, in part, upon its proprietary technology.  The Company does not
     hold any issued 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.

     The Company is also subject to the risk of adverse claims and litigation
     alleging infringement of intellectual property rights of others.  The
     Company could incur substantial costs in defending itself and its customers
     against any such claim regardless of the merits of such claims.  In the
     event of a successful claim of infringement, the Company may be required to
     obtain one or more licenses from third parties.  There can be no assurance
     that the Company could obtain the necessary licenses on reasonable terms.
          
     IMPACT OF YEAR 2000.   Some of the Company's older computer programs were
     written using two digits rather than four to define the applicable year. 
     As a result, those computer programs have time-sensitive software that
     recognize a date using "00" as the year 1900 rather than the year 2000. 
     This could cause a system failure or miscalculations causing disruptions of
     operations, including, among other things, a temporary inability to process
     transactions, send invoices, or engage in similar normal business
     activities.
          

<PAGE>

     The Company has completed an assessment and will have to modify or replace
     portions of its software so that its computer systems will function
     properly with respect to dates in the year 2000 and thereafter.  The total
     Year 2000 project cost is estimated to be immaterial.
          
     The Company has initiated communications with all of its significant
     suppliers and large customers to determine the extent to which the
     Company's interface systems are vulnerable to those third parties' failure
     to remediate their own Year 2000 Issues.  There can be no guarantee that
     the systems of other companies on which the Company's systems rely will be
     timely converted and would not have an adverse effect on the Company's
     systems.  The Company has determined it has immaterial exposure to
     contingencies related to the Year 2000 Issue for the products it has sold.
          
     The Year 2000 project is estimated to be completed not later than December
     31, 1998, which is prior to any anticipated impact on its operating
     systems.  The Company believes that with modifications to existing software
     and conversions to new software, the Year 2000 issue will not pose
     significant operational problems for its computer systems.  However, if
     such modifications and conversions are not made, or are not completed
     timely, the Year 2000 issue could have a material impact on the operations
     of the Company.
          
     The costs of the project and the date on which the Company believes it will
     complete the Year 2000 modifications are based on management's best
     estimates, which were derived utilizing numerous assumptions of future
     events, including the continuous availability of certain resources and
     other factors.  However, there can be no guarantee that these estimates
     will be achieved and actual results could differ materially from those
     anticipated.  Specific factors that might cause such material differences
     include, but are not limited to, the availability and cost of personnel
     trained in this area, the ability to locate and correct all relevant
     computer codes, and similar uncertainties.

     GENERAL.  Sales of networking products fluctuate, from time to time, based
     on numerous factors, including customers' capital spending levels and
     general economic conditions.  While certain industry analysts believe that
     there is a significant market for network intelligent hubs, switches,
     management and security products, there can be no assurance as to the rate
     or extent of the growth of such market or the potential adoption of
     alternative technologies.  Future declines in networking product sales as a
     result of general economic conditions, adoption of alternative technologies
     or any other reason could have a material adverse effect on the Company's
     business, operating results and financial condition.

     Due to the factors noted above and elsewhere in Management's Discussion and
     Analysis of Financial Condition and Results of Operations, the 

<PAGE>

     Company's future earnings and stock price may be subject to significant 
     volatility, particularly on a quarterly basis.  Past financial performance 
     should not be considered a reliable indicator of future performance and 
     investors should not use historical trends to anticipate results or trends 
     in future periods.  Any shortfall in revenue and earnings from the levels 
     anticipated by securities analysts could have an immediate and significant 
     effect on the trading price of the Company's common stock in any given 
     period.  Also, the Company participates in a highly dynamic industry which 
     often results in volatility of the Company's common stock price.

                            REPORT OF INDEPENDENT AUDITORS



The Board of Directors and Stockholders,
ODS Networks, Inc.

We have audited the accompanying consolidated balance sheets of ODS Networks,
Inc., and subsidiaries (the Company) as of December 31, 1997, and 1996, and the
related consolidated statements of income, stockholders' equity, and cash flows
for each of the three years in the period ended December 31, 1997.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

network.  Sales of the Company's products are primarily made directly to major
corporations and government agencies for networking their internal computer
systems and through domestic and international reseller channels.
 .
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

                            PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of ODS Networks, Inc.
and its wholly-owned subsidiaries. Intercompany balances and transactions have
been eliminated in consolidation.

                                  CASH EQUIVALENTS

The Company considers cash and all highly liquid investments purchased with an
original or remaining maturity of less than three months at the date of purchase
to be cash equivalents.  
                                          
                               SHORT-TERM INVESTMENTS

The Company's short-term investments consist of U.S. government obligations,
government agencies, and corporate securities with maximum maturities of one
year.  Short-term investments are classified as available for sale. These
investments are valued at market value, which approximates amortized cost.  The
difference between fair value and amortized cost is not material.

                               RISK CONCENTRATION     

Financial instruments which potentially subject the Company to concentrations of
credit risk are 

<PAGE>

primarily cash and cash-equivalents, investments and accounts receivable.  
The Company places its investments in U.S. government obligations, corporate 
securities and money market funds.  Substantially all of the Company's cash, 
cash equivalents and investments are maintained with one major financial 
institution.

The Company sells its products to customers in diversified industries worldwide,
primarily in North America, Europe, Asia and Latin America.    Fluctuations in
currency exchange rates and adverse economic developments in Malaysia, South
Korea and certain other countries could adversely effect the Company's operating
results.  The Company performs ongoing credit evaluations of its customers'
financial condition and generally requires no collateral.  The Company maintains
reserves for potential credit losses and such losses, in the aggregate, have not
exceeded management expectations.

While the Company believes that many of the materials used in the production of
its products are generally readily available from a variety of sources, certain
components are available from one or a limited number of suppliers. The
inability of any supplier or manufacturer to fulfill supply requirements of the
Company could impact future results.  

                                    INVENTORIES

Inventories are stated at the lower of cost or market.  Cost is computed using
standard cost, which approximates actual cost on a first-in, first-out basis. 
Management estimates the allowance required to state inventory at the lower of
cost or market.  There is a risk that the Company will forecast demand for its
products and market conditions incorrectly and produce excess inventories. 
Therefore, there can be no assurance that the Company will not produce excess
inventory and incur inventory lower of cost or market charges in the future.

                               PROPERTY AND EQUIPMENT

Property and equipment is stated at cost and depreciated on a straight-line
basis over the estimated useful lives of the assets.  Such lives vary from 3 to
20 years.  Leasehold improvements are amortized over the shorter of their useful
lives or the terms of the leases.  Repair and maintenance costs are expensed as
incurred.

                                LONG-TERM INVESTMENTS

Long-term investments consist of U.S. government obligations and corporate
obligations with maturities which range up to two years.  Long-term investments
are classified as available for sale.  These investments are valued at market
value, which approximates amortized cost.  The difference between fair value and
amortized cost is not material.
                                           
                             FOREIGN CURRENCY TRANSLATION

The Company's international subsidiaries use their local currencies as their
functional currencies.  

<PAGE>

Assets and liabilities are translated at the exchange rate in effect at the 
balance sheet date, and income and expense accounts at average exchange rates 
during the year.  Resulting translation adjustments are recorded directly to 
a separate component of stockholders' equity.

                             ACCOUNTING FOR STOCK OPTIONS

The Company has elected to continue to follow APB Opinion No. 25, ACCOUNTING FOR
STOCK ISSUED TO EMPLOYEES, (APB 25) and related interpretations in accounting
for its employee stock options.  Under APB 25, if the exercise price of an
employee's stock option equals or exceeds the market price of the underlying
stock on the date of grant, no compensation expense is recognized.  The
Financial Accounting Standards Board (FASB) has issued Statement of Financial
Accounting Standard (SFAS) No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION,
which provides for either recognition or disclosure of a hypothetical charge for
stock options.  The Company did not recognize any charge in its income
statement, but has provided the required disclosure in Note 8.

                                 NET INCOME PER SHARE

In February 1997, the FASB issued SFAS No. 128, "Earnings per Share" (EPS),
which simplifies existing computational guidelines, revises disclosure
requirements, and increases the comparability of earnings per share on an
international basis.   The Company adopted SFAS No. 128 on December 31, 1997 and
has restated all EPS data presented.    Under SFAS No. 128 the Company is
required to report two separate earnings per share numbers, basic EPS and
diluted EPS.  Diluted EPS is the same number the Company has previously reported
as earnings per share and includes the dilutive impact of employee stock options
and warrants.  

                                REVENUE RECOGNITION

The Company generally recognizes product revenue upon shipment of product.  The
Company accrues for estimated warranty costs, sales returns and other allowances
at the time of shipment based on its experience.  Revenue from maintenance
contracts is deferred and recognized over the contractual period the services
are performed.  To date, warranty costs and sales returns have not been
material.  There is a risk that technical issues on new products could result in
unexpected warranty costs and returns.
                                          
                                  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 reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenue and expenses during the
reporting period.   Estimates are used for,  but not limited to, the accounting
for doubtful accounts, sales discounts, sales returns, warranty costs,
depreciation and taxes.  Actual results could differ from these estimates.

                                     INCOME TAXES

The income tax provision is based on pretax financial accounting income or 
loss. The Company 

<PAGE>

accounts for income taxes pursuant to SFAS No. 109, ACCOUNTING FOR INCOME 
TAXES, which uses the liability method to calculate deferred income taxes.  
Deferred tax assets and liabilities are recognized for the expected tax 
consequences of temporary differences between the tax basis of assets and 
liabilities and their reported amounts. The realization of deferred tax 
assets is based on historical tax positions and expectations about future 
taxable income. 
                                           
                                   RECLASSIFICATION

Certain amounts in prior year financial statements have been reclassified to
conform with current year presentation.

4.  LINE OF CREDIT

<PAGE>

The Company has a bank line of credit agreement that allows the Company to
borrow amounts up to $15.0 million. Borrowings under this line are secured by
the Company's accounts receivable and inventory and are subject to certain
limitations and conditions, including the maintenance of certain financial
ratios and minimum net tangible worth amounts.  The Company is also restricted
under this agreement as to the payment of dividends.

Borrowings accrue interest at prime (8.5% at December 31, 1997) with interest
due monthly and principal due April 12, 1999.  A fee of 0.2% is paid quarterly
on the average unused portion of the line of credit. 

At December 31, 1997, the Company had no borrowings outstanding under this line

EMPLOYEE BENEFIT PLANS
  
EMPLOYEE STOCK PURCHASE PLAN

  On April 24, 1997 the Company adopted an Employee Stock Purchase Plan (the
Purchase Plan) under which 0.5 million shares of common stock have been reserved
for issuance.  Eligible employees may designate not more than 10% of their
compensation to be deducted each pay period for the purchase of common stock
under the Purchase Plan, and each participant may purchase up to 500 shares in
any one calendar year. On January 31 and August 31 of each calendar year, shares
of common stock are purchased with the employees' payroll deductions over the
immediately preceding six months at a price per share of 85% of the lesser of
the market price of the common stock on the purchase date or the market price on
the first day of the six-month period.  The Purchase Plan will terminate no
later than April 24, 2007. Subsequent to December 31,1997, 10,311 shares of
stock were issued under the Purchase Plan for an aggregate purchase price of
$65,784 related to the purchase period which commenced on August 1, 1997 and
ended on January 31, 1998. 

<PAGE>
 
 EMPLOYEE  401(k) PLAN

The Company has adopted a plan known as the ODS 401 (k) Savings Plan (the Plan)
to provide retirement and incidental benefits for its employees.  The Plan
covers substantially all employees who meet minimum age and service
requirements.  As allowed under Section 401(k) of the Internal Revenue Code, the
Plan provides tax deferred salary deductions for eligible employees.

Employees may contribute from 1% to 19% of their annual compensation to the
Plan, limited to a maximum amount as set by the Internal Revenue Service.  The
Company matches employee contributions at the rate of $0.25 per each $1.00 of
contribution on the first 4% of deferred compensation.  Company matching
contributions to the Plan were approximately $121,000, $110,000, and $83,000 in
1997, 1996 and 1995, respectively.

8. STOCK OPTIONS AND WARRANTS

At December 31, 1997, the Company has four stock-based compensation plans, which
are described below.  The Company established an Incentive Stock Option Plan in
1983, which provides for the issuance of options to key employees of the Company
to purchase common stock of the Company.  The 1983 Incentive Stock Option Plan
was terminated on November 10, 1993.  

In 1987, an additional Incentive Stock Option Plan was established with similar
provisions to allow for further issuance of options. The 1987 Incentive Stock
Option Plan was terminated on January 26,1997.  Each plan provides for the
issuance of up to 1.2 million shares of common stock upon exercise of options
granted pursuant to the plans.

In 1995, the Company adopted the 1995 Stock Option Plan (the 1995 Plan) which
provides for the issuance of up to 1.6 million shares of common stock upon
exercise of options granted pursuant to the 1995 Plan.  The 1995 Plan provides
for the issuance of both non-qualified and incentive stock options to employees,
officers, and employee-directors of the Company.

In 1995, the Company adopted the 1995 Non-employee Director Stock Option Plan
(the 1995 Non-employee Director Plan) which provides for the issuance of up to
160,000 shares of common stock upon exercise of options granted pursuant to the
1995 Non-employee Director Plan.  The Plan provides for the issuance of
non-qualified stock options to non-employee directors.

In 1995 and 1994, options to purchase 60,000 shares, and 12,000 shares,
respectively, were granted to directors.  The terms and exercise prices of these
options are similar to the incentive stock options.

Common shares reserved for future grants under all of the stock option plans
described above amounted to 1.1 million shares at December 31, 1997.     

The Compensation Committee of the Board of Directors determines the term of each
option, option exercise price within limits set forth in the plans, number of
shares for which each option is granted and the rate at which each option is
exercisable (generally ratably over five years from grant date).  However, the
exercise price of any incentive stock option may not be less than the fair
market value of the shares on the date granted (or less than 110% of the fair
market value in the case of optionees holding more than 10% of the voting stock
of the Company), and the term cannot exceed ten years (five years for incentive
stock options granted to holders of more than 10% of the Company's voting
stock).

FAS No. 123, ACCOUNTING FOR STOCK BASED COMPENSATION, requires the disclosure of
pro forma net income and earnings per share information computed as if the
Company had accounted for its employee stock options granted subsequent to
December 31, 1994, under the fair value method set forth in SFAS 123. The fair
value for these options was estimated using a Black-Scholes option pricing model
with the following weighted-average assumptions:

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable.  In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility.  Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.  In addition, because
SFAS 123 is applicable only to options granted subsequent to December 31, 1994,
the pro forma information does not reflect the pro forma effect of all previous
stock option grants of the Company, and thus the pro forma information is not
necessarily indicative of future amounts until SFAS 123 is applied to all
outstanding stock options. 

Information relating to the fair value of option grants made during 1997, 1996
and 1995 is as follows:

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the options' vesting period.  For purposes of pro
forma disclosure, the Company assumed that it would not receive a tax deduction
or tax benefit for financial reporting purposes related to incentive stock
options.  In management's opinion, the pro forma disclosure is not necessarily
indicative of the net financial effect assuming the Company was required to
expense the fair value of employee stock options because an incentive stock
option often generates a tax deduction for the Company because the stock option
holder does not comply with the holding period requirements under applicable tax
laws.  The Company's pro forma information follows (in thousands, except
earnings per share information):

EXCHANGE OF STOCK OPTIONS SUBSEQUENT TO DECEMBER 31, 1997

     On January 21, 1998, the Compensation Committee of the Board of Directors
approved a stock option exchange program (the Exchange Program), pursuant to
which certain employees and officers holding incentive stock options (i) awarded
under the Company's 1987 Incentive Stock Option Plan in 1997 and (ii) awarded
prior to December 31, 1997, under the Company's 1995 Stock Option Plan (the 1995
Plan), were given the opportunity to exchange such options (Existing Options)
for new options (New Options), based on the fair market value of the Company's
Common Stock at the close of business on January 30, 1998.  All directors of the
Company, including  the President and Chief Executive Officer, and the  Senior
Vice President were ineligible to participate in the Exchange Program.

     As a result of significant declines in the market value of the Company's
Common Stock since issuance of the Existing Options, the Existing Options were
exercisable at prices which substantially exceeded the market value of the
Common Stock.  In approving the Exchange Program and in keeping with the
Company's philosophy of utilizing equity incentives to motivate and retain
qualified employees, the Compensation Committee acknowledged that retention and
attraction of qualified employees are critical to the Company's success and its
ability to continue to meet its performance objectives.  Additionally,
recognizing that stock options constitute a significant component of the
Company's compensation structure, the Compensation Committee deemed it important
to regain the incentive intended to be provided by the New Options to purchase
shares of the Company's Common Stock and therefore 

<PAGE>

serve as a significant factor in the Company's ability to continue to attract 
and retain the services of superior quality personnel.

     Pursuant to the Exchange Program, holders of the Existing Options were
offered the opportunity to exchange, on a share-for-share basis, such options
for New Options having an exercise price of $7.50 per share, the fair market
value of the Company's Common Stock on the exchange date of January 30, 1998. 
Each New Option was awarded under the 1995 Plan and vests and is exercisable
with respect to 20% of the shares covered thereby on each anniversary date
thereof. Eligible employees holding Existing Options for an aggregate of 646,800
shares of Common Stock with an average per share exercise price of approximately
$15.87 elected to participate in the Exchange Program and were issued New
Options covering the same aggregate number of underlying shares as they had held
pursuant to their respective Existing Options.  Other than the new exercise
price and the commencement of a new vesting schedule, the option agreements
relating to the New Options are substantially identical to the option agreements
of the Existing Options they replaced. FAS 123 proforma information does not
reflect this exchange as approval of the program was not granted until 1998.


9. MAJOR CUSTOMERS AND GEOGRAPHIC INFORMATION

The Company's operations are concentrated in one segment - the design,
development and manufacture of local area network products.  Sales to customers
exceeding 10% of total sales were as follows: 1997 - $14.9 million to EDS and
$10.8 million to various agencies of the U.S. Government (aggregated as one). ;
1996 - $22.9 million to EDS, $15.9 million to various agencies of the U.S.
Government (aggregated as one) and $14.2 million to AT&T; 1995  - $31.6 million
to EDS and $13.4 million to AT&T.  A large portion of sales to AT&T in 1995 were
attributable to a major U.S. Army customer of AT&T.

Export sales, primarily to Europe, Asia, Latin America and Canada, were $25.1
million in 1997, $17.1 million in 1996, and $12.9 million in 1995.
