ITEM 1.  BUSINESS
 
GENERAL
 
     Bay Networks, Inc. (the "Company") develops, manufactures, markets and
supports a comprehensive line of data networking products and services,
including high-speed routers, switches, intelligent hubs, remote and internet
access solutions and sophisticated management software providing network design
and configuration solutions. These products enable end users to build or enhance
their data network systems, including all levels from small local area networks
to large enterprise-wide information infrastructures.
 
     In October 1994, SynOptics Communications, Inc. ("SynOptics") and Wellfleet
Communications, Inc. ("Wellfleet") effected a strategic combination of the two
companies through the merger of a wholly-owned subsidiary of Wellfleet with and
into SynOptics (the "Combination"). In connection with the Combination,
Wellfleet changed its name to Bay Networks, Inc. On May 15, 1995, the Company
acquired Centillion Networks, Inc. a leading provider of Token Ring and Token
Ring-to-ATM switching products.
 
     On December 15, 1995, the Company acquired Xylogics, Inc. ("Xylogics"), a
technology and market leader in enterprise remote access, offering remote users
and offices transparent corporate-wide access to networking resources. On March
13, 1996, the Company acquired all of the outstanding shares of Performance
Technology, Inc., a privately held company headquartered in San Antonio, Texas
and a leader in developing LAN-to-Internet access technology, providing small
offices and small-to-medium-sized businesses easy, secure access to the
Internet. On March 31, 1996, the Company acquired substantially all of the net
assets of Armon Networking, Ltd., headquartered in Tel Aviv, Israel, a
technology developer of RMON-based distributed analysis tools and multi-segment
LAN probes. In June 1996, the Company signed a definitive agreement to acquire
the Digital Signal Processing (DSP) modem business of Penril DataComm Networks,
Inc., a provider of advanced DSP-based modems and remote access products. The
closing of the transaction is currently expected to be in the quarter ending
December 31, 1996. See Management's Discussion and Analysis of Financial
Condition and Results of Operations and Note 2 to the Consolidated Financial
Statements included herein.
 
     The Company's products connect and interconnect multiple types of LANs,
comprised of computer equipment from the same or different manufacturers, to
form an internetworked system. These products connect computers to form LANs,
interconnect LANs located in a single facility and, through WAN connections, may
connect LANs dispersed around the world. The internetworking of these networks
enables computer users operating different types of equipment in different
locations to communicate, exchange data and share other computing resources.
 
     The Company is a Delaware corporation incorporated in May, 1986. The
Company's principal offices are located at 4401 Great America Parkway, Santa
Clara, California 95054.
 
     Trademarks of Bay Networks, Inc. appear in this document. Other trademarks,
brand, product, or company names may be the property of others.
 
RECENT DEVELOPMENTS
 
     On September 3, 1996, the Company signed a definitive agreement to acquire
all the outstanding shares of LANcity Corporation ("LANcity"), a provider of
advanced cable modem technology, in exchange for $59.0 million. The acquisition
is subject to LANcity shareholder approval and is scheduled to close during the
quarter ending September 30, 1996. The acquisition will be accounted for as a
purchase. Based on preliminary estimates, the Company expects to allocate
approximately one-half of the purchase price to in-process research and
development, which will be charged to expense upon the closing of the
transaction.

NETWORKING SOLUTIONS
 
     Organizations are increasingly seeking to internetwork their disparate,
often incompatible, LANs and WANs to share information and computing resources
across the organization for applications such as electronic mail, sharing of
databases, multi-site engineering and product development, transaction
processing and electronic image transfer. Enterprise-wide networks facilitate
efficient and rapid data communications among connected work groups, departments
and locations and provide for more effective utilization of information and
computer resources. In addition, as the computing paradigm migrates to
client-server architectures, enterprise-wide networks are the enabler that
allows those technologies to be implemented by organizations. The
internetworking of LANs and WANs into enterprise-wide networks requires data
communications products which efficiently, reliably, and quickly transmit data
to appropriate locations on different networks, reconcile incompatible LAN and
WAN standards between networks and manage large, complex internetworks.
 
     To meet these internetworking needs, the Company has developed a family of
computer networking products including hubs, routers, switches, and network
management software. The Company's hub products, which reside at the center of
networks and serve as a control and consolidation point for network activity,
integrate connectivity, network management and internetworking products into a
structured network solution that emphasizes network management scalability and
manages complexity across the network.
 
     As network demands continue to increase, switching delivers the performance
required to support the emerging image processing, animation, modeling,
scientific and multimedia applications of the future. The Company's router
products choose the optimal path to interconnect LANs or to route data to the
WAN. These products enhance network segmentation and security, improve
reliability (since alternative paths can be used) and increase bandwidth
utilization (since the best path between source and destination is chosen by a
router).
 
     Organizations are experiencing a shift from departmental-only to
enterprise-wide remote access and the need for applications and network
infrastructure that are remote access-ready as a result of increased business
mobility, the move to telecommuting, reduced cost of ownership of both product
and WAN services, and widespread adoption of remote access standards. Remote and
internet access products extend the backbone network beyond the branch office,
bringing remote users closer to the enterprise and permit connection to the
corporate LAN so users can work anywhere -- at home, in a hotel or in a remote
office -- at any time. Users can access electronic mail, databases and file
servers as if they were directly included within the network.
 
PRODUCTS
 
     The Company's product lines include a broad family of internetworking
products, including routers, hubs, switches, remote and internet access
solutions, and network management technologies. These products encompass LAN and
WAN components, which allow the Company to offer a solution to communicate
network data worldwide, managed from a single network management software
platform which supports the Company's product lines.
 
     The Company's product strategy is focused on weaving LAN connectivity,
management and internetworking solutions into a flexible network fabric capable
of supporting large, diverse enterprise networks. The center of this strategy is
the intelligent hub, which acts as a central control point for network
connections, management and growth. The intelligent hub incorporates the
hardware and software required to connect computing devices to structured
networks using various cabling types and media-access methods, switches, bridges
and routers that enable the internetworking of various network segments into
enterprise networks. Integrated network management software products facilitate
network operation by diagnosing and solving network problems. The categories of
the Company's product lines are described below.
 
     Connectivity Products, which include intelligent hubs and related host
modules and transceivers, enable computing devices to communicate over networks.
Intelligent hubs provide integrated connectivity and centralized management by
supporting ethernet, token ring and fiber distributed data interface ("FDDI")
protocols, or any combination of the three in the same hub. Transceivers provide
an interface between the
 
                                        2
<PAGE>   4
 
computing devices and cabling systems and are implemented either as units
external to the computer or as integrated circuits on network cards.
 
     Network Management Products distribute management intelligence throughout
geographically dispersed networks and enable network administrators to monitor
and control the network. The open, standards-based network management products
are comprised principally of intelligent modules which resides within hubs,
sophisticated management software which resides on intelligent modules and
advanced software application programs which reside on network management
computer consoles. Through a combination of hardware and software components,
intelligent network management modules gather network information close to the
source of data activity, reduce it into meaningful information within the hub,
and forward the data to a central network management console attached to the
network. The actual management of data takes place in the hub, relieving the
burden on central network management resources and enabling networks to grow
along with the expansion of the business.
 
     Using the Simple Network Management Protocol ("SNMP"), which ensures
compatibility with other management systems that may already be in place in a
particular networking environment, the Company's network management products
address a wide variety of diverse environments. The Optivity network management
system works with DOS and UNIX network management platforms from International
Business Machines Corporation, Hewlett-Packard Company, Inc., Novell, Inc. and
Sun Microsystems, Inc. Additionally, the Company offers application software
products which automate operational functions and facilitate design and
management of a network. The flexibility of these software products enable them
to interface in an array of multi-vendor environments.
 
     Internetworking Products are modular devices integrated into intelligent
hubs or stand-alone devices which provide links between independent LAN segments
and control the flow of data on the LAN. The devices connect data traffic
between linked networks and forward packets of data destined for other locations
throughout the network. The Company's internetworking product lines include
local and remote bridges, local and remote routers, and switches. Bridges, which
are protocol-independent, are the simplest method of connecting LAN segments.
Bridges sort through all traffic on a network, and decide whether to send it to
the remainder of the network.
 
     As networks grow in both size and complexity, routers provide additional
intelligence in connecting individual networks. Unlike bridges, routers actually
examine the protocol of the data packets which permits protocol filtering and
security control. The Company offers a family of scalable and highly flexible
router products that concurrently provide bridging and multi-protocol routing
functions in modular and stackable forms. The Backbone Node ("BN") products are
designed to satisfy the throughput and/or availability requirements of the most
demanding enterprise internetworks. The Backbone Node provides complete fault
resiliency with redundant processor interconnects, power supplies, and software
image storage in combination with its symmetric multiprocessor architecture.
 
     The Company also offers a modular, stackable router, which is designed to
provide seamless integration of multiple units stacked together, performing as a
single router. This modular product offers scalability for expanding sites
requiring remote, regional or departmental access to the corporate network.
 
     Switching Products interconnect LANs by supporting multiple parallel
communications and eliminating LAN bandwidth congestion. These products offer
connectivity to LAN and WAN technologies such as asynchronous transfer mode
("ATM"), FDDI and token ring, as well as a full suite of networking protocols
for high-speed LAN and switching environments.
 
     In fiscal 1995, the Company introduced BaySIS (Bay Switched Internetworking
Services), a new networking architecture that combines switching technology with
traditional shared-media hub and router technology. The resulting
switched-internetworking architecture permits the customer to migrate from their
existing technology in a controlled, reliable and cost-effective manner.
 
     Remote and Internet Access Products, including Remote Annex analog remote
access servers, Nautica ISDN router products and Instant Internet internet
access server, which are key to on-line access
 
                                        3
<PAGE>   5
 
to corporate information and services such as the Internet, extend the backbone
network beyond the branch office, bringing remote users closer to the
enterprise.
 
     The Remote Annex family of products, which are highly scalable and are
offered in a variety of configurations, provide users with transparent dial-in
access to Ethernet LANS. Users can access electronic mail, data bases and file
servers residing on Novell NetWare, TCP/IP and AppleTalk LANs as if they were
directly included with the network.
 
     ISDN is a digital telephone connection that accommodates high bandwidth
transmissions such as graphics, images or large text files and provides an
immediate, high speed, reliable connection to network resources. The Nautica
series of ISDN routers support a wide range of routed protocols including Novell
IPX/SPX, TCP/SP, Netbios, Microsoft WINS and Banyan Vines as well as the OSPF
and RIP2 routing protocols. These products provide bandwidth-on-demand,
dial-on-demand, data compression security, configuration and network management
features.
 
     Instant Internet provides small offices and small-to-medium-sized
businesses easy, secure access to the internet, by providing an all-in-one unit
to connect NetWare, Windows '95 and Windows NT users directly to the internet
without requiring any time-consuming changes to LAN clients or servers.
 
SALES CHANNELS
 
     The Company's global market strategy emphasizes the support of sales and
service through a network of value added resellers ("VARs"), distributors,
networking OEMs and, through its domestic field sales force, directly to major
customers. The goal of the multi-channel strategy is to offer the Company
flexibility to meet specific needs and furnish the Company with broad coverage
of worldwide markets.
 
     Value Added Resellers.  VARs integrate the Company's products, along with
products sold by other LAN and WAN vendors, into turnkey networking systems that
are sold directly to end users. VARs also sell the Company's products as
stand-alone units. The Company provides support to the VAR network through its
field sales force and customer service organization, so that in addition to
sales generated independently, VAR sales are also the result of sales leads
generated by the Company's direct marketing efforts. Sales to VARs are made at
discounts based on purchase volumes and other incentive programs. VARs may
choose to procure the the Company products they resell by purchasing directly
from the Company or from its distributors as described below.
 
     Distributors.  The Company also sells its products to distributors who
typically resell to VARs or other dealers. Distributors must meet certain
criteria that are substantially different from those which the Company's VARs
must meet. The Company's distributors generally provide a minimal level of
systems integration. Distributors purchase at standard discounts based on
certain incentive programs. The Company offers additional sales and marketing
programs to assist those VARs and dealers who purchase through distributors in
promoting, selling and supporting the Company's products.
 
     The Company's VARs and distributors may carry other products which are
complementary to, or compete with those of the Company, and these non-exclusive
VARs and distributors may choose to give higher priority to products of other
suppliers or competitors.
 
     Field Sales Force.  The Company's field sales force manages its sales
activities through multi-channel distribution strategies. The Company's
customers include end-users of large, complex, enterprise-wide networks, who
typically provide their own systems integration. The field sales and technical
support force also provides training and technical support to the Company's
VARs, distributors and end-users.
 
     Marketing.  The Company has implemented several marketing programs designed
to support the sale of its products through broad-scale reseller distribution
(two-tier distributors and direct resellers), generate sales leads for its
distribution channels and enhance brand name recognition. The Company's
marketing activities include frequent participation in industry trade shows and
seminars, advertisements in major trade publications worldwide, publications of
technical articles in the trade press, the distribution of sales literature and
 
                                        4
<PAGE>   6
 
product specifications and ongoing communications with its installed base of
end-user customers. The Company's reseller and distribution programs include
incentives and benefits such as Co-op and reseller marketing programs.
 
CUSTOMERS AND BACKLOG
 
     The Company's product backlog on June 30, 1996, was approximately $120
million as compared to product backlog on June 30, 1995, of approximately $231
million. The Company includes in its backlog only orders confirmed with a
purchase order for products to be shipped within six months. Because of the
generally short cycle between order and shipment, and occasional customer
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 necessarily indicative of actual net sales for any future
period. One reseller, Anixter Inc., a wholly-owned subsidiary of Anixter
International, Inc., accounted for approximately 13% ($263.0 million), 14%
($198.0 million) and 14% ($162.0 million) of the Company's revenue in fiscal
1996, fiscal 1995 and fiscal 1994, respectively.
 
     The Company has attempted to reduce its product manufacturing lead times
and its backlog of orders. To the extent that backlog is reduced during any
particular period, it could result in more variability and less predictability
in the Company's quarter to quarter revenue and operating results. If
manufacturing lead times are not reduced, the Company's customers may cancel, or
not place, orders if shorter lead times are available from other manufacturers.
In addition, the Company's ability to meet customer demand may also be dependent
on the ability of the Company to increase manufacturing levels for new products
to volumes based on anticipated orders by the market.
 
CUSTOMER SUPPORT, SERVICE AND WARRANTY
 
     The Company services, repairs and provides technical support for its
products. A significant portion of the Company's service and support activities
is related to software and network configuration and is provided by the
Company's assistance centers. The Company has contracted with third parties to
supplement service provided directly by the Company for on-site hardware
maintenance. International service is provided primarily by distributors,
supplemented with phone support centers in France, Japan and Australia. The
Company sells products to end-users with warranty periods of up to twelve months
from the date of shipment for domestic sales and up to fifteen months from the
date of shipment for international export sales. Following the expiration of the
warranty period, if any, the Company offers services under maintenance contracts
or on a time and materials basis. The Company also provides on-site network
support services such as system installation, network integration services and
technical consulting.
 
RESEARCH AND DEVELOPMENT
 
     The Company has devoted significant resources to research and development,
spending $213.5 million, $145.3 million and $117.6 million during the fiscal
years ended June 30, 1996, 1995 and 1994, respectively.
 
     During fiscal 1996, the Company continued development of enhancements to
its current products and to the development of new products in the areas of
emerging technologies such as ATM, remote access, switched internetworking
technologies, and the integration of voice, video and data networking. The
Company plans to continue its commitment to research and development in fiscal
1997, as the Company believes that the markets for its products are
characterized by rapid rates of technological innovation for both hardware and
software.
 
MANUFACTURING
 
     The Company's manufacturing operations are located at its Santa Clara and
Sunnyvale, California; Billerica and Burlington, Massachusetts; Tel Aviv, Israel
and San Antonio, Texas facilities. The Company uses contract manufacturers in
the United Kingdom for its Nautica(TM) product line to meet product demands for
the United Kingdom market.
 
                                        5
<PAGE>   7
 
     The Company's manufacturing process consists of purchasing; automated,
semi-automated and manual assembly; burn in processing; in-circuit testing;
final assembly and test; and inspection.
 
     Most of the components used in the Company's products are available from
more than one supplier. Failure of the Company's vendors to supply required
items could have a material adverse effect upon the Company's business. The
Company seeks to maintain an inventory level sufficient to meet its anticipated
short-term production needs. In the past, the Company has paid premiums to
secure adequate supplies of components, and it could become necessary to make
such payments again in the future.
 
COMPETITION
 
     The data networking industry has grown in the past few years, however, the
Company's revenue may fluctuate year over year or any quarter over quarter based
on competition and customers waiting for anticipated product introductions. The
networking industry is highly competitive and competition is expected to
intensify and could adversely affect the Company's future results. Networking
and communications suppliers compete in areas such as: conformity to existing
and emerging industry standards; interoperability with other networking
products; the ability to run Ethernet, token ring and FDDI networks on most
common cabling systems; network management capabilities; ease of use;
scalability; price; performance; reliability; product features; technical
support; marketing expertise; and product innovation.
 
     There are many companies competing in various segments of the intelligent
hub, switching, router and remote access network markets. The Company's
principal competitors include Ascend Communications, Cabletron Systems, Inc.,
Cascade Communications, Cisco Systems, Inc., Digital Equipment Corporation, Fore
Systems, Inc., Hewlett-Packard Company, Inc., International Business Machines
Corporation and 3Com Corporation, among others. Several of the Company's
competitors have greater name recognition, more extensive engineering,
manufacturing and marketing capabilities, and greater financial, technological
and personnel resources than those available to the Company. In addition,
certain companies in the networking industry have expanded their product lines
or technologies in recent years as a result of acquisitions. Specifically, 3Com
Corporation acquired Chipcom Corporation and Cisco Systems, Inc. recently
acquired Stratacom, Inc. Cisco Systems, Inc. also recently announced its
intention to acquire Telebit Corporation. There can be no assurance that the
Company will be able to compete successfully in the future with existing or new
competitors.
 
     With industry standards established and new standards emerging, more
companies have developed standards-based products and have sought to compete on
the basis of price. Pressures from competitors offering lower priced products
could result in future price reductions for the Company's products.
 
PROPRIETARY RIGHTS AND LICENSES
 
     The Company currently relies upon a combination of patents, copyrights,
trademarks and trade secret laws to establish and protect its proprietary rights
in its products. The Company maintains as proprietary the software and other
portions of the technology incorporated in its network management and other
products, and may license that technology to others as necessary. There can be
no assurance that the steps taken by the Company in this regard will be adequate
to prevent misappropriation of its technology or that the Company's competitors
will not independently develop technologies that are substantially equivalent or
superior to the Company's technology. In addition, the laws of some foreign
countries do not protect the Company's proprietary rights to the same extent as
do the laws of the United States. The Company has a number of patents and may
apply for additional patents. There can be no assurance that patents will issue
from any applications filed by the Company or that, if patents do issue, the
claims will be sufficiently broad to protect the technology invented by the
Company. In addition, no assurance can be given that any patents issued to the
Company will not be challenged, invalidated or circumvented or that the rights
granted thereunder will provide competitive advantages.
 
     Because of the existence of a large number of patents in the networking
field and the rapid rate of issuance of new patents or new standards that may
issue or to obtain important technology, it may be necessary for the Company to
enter into technology licenses from others. Such licenses could impact the
 
                                        6
<PAGE>   8
 
Company's operating results, and there is no assurance that the Company will be
able to license such technology.
 
EMPLOYEES
 
     As of June 30, 1996, the Company employed 5,758 persons, including regular,
temporary and contract employees, none of whom is represented by a labor union.
The Company has experienced no work stoppages and considers its employee
relations to be positive.
 
ITEM 2.  PROPERTIES
 
     The Company's principal executive facility is located at the Company's
corporate headquarters in Santa Clara, California. The Company has eastern

ITEM 7.
 
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
     Business Environment and Risk Factors.  The following discussion should be
read in conjunction with the consolidated financial statements and related notes
included elsewhere herein as well as the section below under the heading "Risk
Factors That May Affect Future Results". The Company's future operating results
may be affected by various trends and factors which are beyond the Company's
control. These include, among other factors, changes in general economic
conditions, rapid or unexpected changes in technologies and uncertain business
conditions that affect the data networking industry. Accordingly, past results
and trends should not be used by investors to anticipate future results or
trends.
 
     With the exception of historical information, the matters discussed below
under the headings "Results of Operations" and "Liquidity and Capital Resources"
may include forward-looking statements that involve risks and uncertainties. The
Company wishes to caution readers that a number of important factors, including
those identified in the section entitled "Risk Factors That May Affect Future
Results," as well as factors discussed elsewhere in this report and in the
Company's other reports filed with the Securities and Exchange Commission, could
affect the Company's actual results and cause actual results to differ
materially from those in the forward-looking statements.
 
Results of Operations
 
     Revenue.  Revenue increased 46.5% to $2,056.6 million in fiscal 1996 as
compared to $1,403.6 million in fiscal 1995 and $1,136.4 million in fiscal 1994.
The growth in revenue in fiscal 1996 was attributable to market growth and
strong demand for the Company's products. This growth was a result of worldwide
unit volume increases for virtually all of the Company's product lines. While
sales in all major product areas increased, the highest percentage increase was
in the switching product line; the Company's new products in the remote access
market, including the Xylogics' Nautica line, were particularly well received in
those markets. Revenue from the router product line grew over fiscal 1995 as
sales to the telecommunications industry increased. The increase in revenue in
fiscal 1995 was attributable to growth in market demand for the Company's
products with growth across all of the Company's product lines. The Company has
continued to increase revenue through execution of its multi-channel
distribution strategy and growth in international operations.
 
     International revenue was $716.5 million or 34.8% of total revenue in
fiscal 1996, compared to $458.4 million or 32.7% of total revenue and $345.7
million or 30.4% of total revenue in fiscal 1995 and fiscal 1994, respectively.
The increase in each period was primarily due to the Company's international
expansion and growth in the Asia/Pacific market, as well as continued growth in
the European market. The Company continues to emphasize the multi-channel sales
strategy which consists of qualified resellers, distributors and dealers. The
Company's international revenue was primarily denominated in U.S. dollars. The
effect of foreign exchange rate fluctuations did not have a significant impact
on the Company's operating results in any period.
 
     Revenue in past periods may not be indicative of revenue in the future,
which may be affected by other business environment and risk factors previously
discussed, as well as other factors included elsewhere herein.
 
     Gross Profit.  Gross profit was $1,111.3 million or 54.0% of revenue in
fiscal 1996, compared to $772.6 million or 55.0% of revenue and $630.7 million
or 55.5% of revenue in fiscal 1995 and fiscal 1994, respectively. The gross
profit increase was due to sequentially higher worldwide unit volume each year.
The gross margin percentage decline in fiscal 1996 was affected by several
factors: a product mix shift towards shared media, including increased volumes
of stackable Ethernet products, and additional reserves for excess inventory as
a result of product transitions that occurred in fiscal 1996. The decline was
partially offset by manufacturing cost reductions, reductions in material
premium charges, and increased router sales which carry higher margins. The
decline in fiscal 1995 was primarily from competitive list price reductions,
product mix shifts toward non-modular products which carry lower margins, and
price increases on certain components.
 
     The Company believes there is a risk that gross margin percentages may
decline if the product mix continues to shift towards non-modular products and
competition continues to increase. The Company expects
 
                                       12
<PAGE>   14
 
market emphasis on lower margin routers and high-speed switching products in the
future. Other factors, including changes in material and labor costs and
distribution channels, may also have an adverse effect on gross margin
percentages in the future.
 
     Operating Expenses.  Research and development spending grew by 46.9% to
$213.5 million in fiscal 1996 from $145.3 million in fiscal 1995 and 23.6% from
$117.6 million in fiscal 1994 as compared with fiscal 1995, although the
percentage of revenue of 10.4% remained constant for each fiscal year. The
increase in expense relates to the Company's continued development of
enhancements to its current products and to the development of new products and
addition of personnel through hiring and through acquisitions and business
combinations. During the year, the Company continued development of new products
in the areas of emerging technologies such as ATM, remote access, switched
internetworking technologies, and the integration of voice, video and data
networking. The Company plans to continue its commitment to research and
development in fiscal 1997, as the Company believes that the markets for its
products are characterized by rapid rates of technological innovation for both
hardware and software. Research and development expenses may increase in
absolute dollars in future periods, and such expenditures may vary as a
percentage of revenue. There can be no assurance that the Company's research and
development efforts will result in commercially successful new technology and
products in the future, and those efforts may be affected by other factors noted
below.
 
     Selling and marketing expenses were $452.3 million or 22.0% of revenue in
fiscal 1996, compared to $302.5 million or 21.6% of revenue and $246.8 million
or 21.7% of revenue in fiscal 1995 and fiscal 1994, respectively. The increase
in expense in both fiscal 1996 and fiscal 1995, as compared with the prior
fiscal year, was primarily related to the increased costs associated with larger
sales and sales support staffs, commission expenses resulting from higher sales
levels, expansion of the Company's sales and marketing programs, and investments
related to new product launches and entry into new markets worldwide. The
Company's investment in its sales, marketing and support staff may vary as a
percentage of revenue in the future.
 
     General and administrative expenses were $72.2 million or 3.5% of revenue
in fiscal 1996, compared to $55.7 million or 4.0% of revenue and $47.5 million
or 4.2% of revenue in fiscal 1995 and fiscal 1994, respectively. The absolute
dollar increase in general and administrative expenses each year related to the
addition of personnel, and expenditures related to both domestic and
international facilities and information technology needed to support the growth
in the Company's business. General and administrative expenses may vary as a
percentage of revenue in the future.
 
     In fiscal 1996, the Company acquired all of the outstanding shares of
Performance Technology, Inc., a developer of LAN-to-Internet access technology,
for a total purchase price of $12.6 million, and substantially all of the net
assets of Armon Networking, Ltd., a technology developer of RMON-based
distributed analysis tools and multi-segment LAN probes, for a total purchase
price of $34.2 million. Approximately $39.7 million was charged to in-process
research and development related to internetworking technologies associated with
these acquisitions.
 
     The Company incurred in-process research and development expenses of $6.7
million and $17.9 million related to the acquisitions of Scorpion Ltd. and Coral
Network Corporation in fiscal 1995 and 1994, respectively.
 
     In June 1996, the Company signed a definitive agreement to acquire the
Digital Signal Processing (DSP) modem business of Penril DataComm Networks,
Inc., a provider of advanced DSP-based modems and remote access products. Based
on preliminary estimates, the Company expects to allocate approximately $60
million to $65 million of the total purchase price, which is based on a fixed
formula, to in-process research and development, which will be charged to
expense upon the closing of the transaction, currently expected to be in the
quarter ending December 31, 1996.
 
     As a result of the various business combinations in fiscal 1996 and 1995,
the Company has incurred merger related expenses of $16.1 million and $63.4
million, respectively. These merger related expenses related to transaction
costs, severance related expenses, closing of duplicate facilities, write off of
duplicate inventory and other assets and other costs incident to the
transactions. In fiscal 1996, the Company reversed previously accrued merger
costs of $5.9 million associated with the Wellfleet/SynOptics business
combination
 
                                       13
<PAGE>   15
 
and the Centillion acquisition. The reduction in the estimated costs were
realized primarily due to the usage of facilities which the Company had
previously planned to vacate. (See Note 2 to the Notes to Consolidated Financial
Statements.)
 
     Net Interest Income and Other.  Net interest income and other was $28.5
million, or 1.4% of revenue in fiscal 1996, compared to $21.8 million or 1.6% of
revenue and $7.3 million or 0.6% of revenue in fiscal 1995 and fiscal 1994,
respectively. The increase in absolute dollars in interest income was due to
higher average invested cash and investment balances, which yielded higher
interest income in fiscal year 1996 and 1995.
 
     Income Taxes.  The Company's effective income tax rate was 37.5%, 37.8% and
37.6% in fiscal 1996, fiscal 1995 and fiscal 1994, respectively, and excludes
the effect of the in-process research and development charges and certain merger
related expenses which were not deductible for income tax purposes. At June 30,
1996, a valuation allowance of $6.8 million was offset against the net operating
losses and credit carryforwards acquired from Coral Network Corporation,
Centillion Networks, Inc. and Performance Technology, Inc. which are subject to
substantial limitation. Management has concluded that other than the allowance
related to these acquisitions, no valuation allowance is required based on its
assessment that future levels of taxable income will be sufficient to realize
the future tax benefits represented by the deferred income taxes.
 
     Liquidity and Capital Resources.  As of June 30, 1996, total cash and
short- and long-term investments totaled $588.2 million, down from $651.6
million at June 30, 1995. Cash generated from operating activities declined to
$105.9 million, compared to $258.1 million and $169.0 million in fiscal 1995 and
fiscal 1994, respectively.
 
     Cash provided from operations decreased from the prior year due to an
increase in income before depreciation and amortization which was more than
offset by increases in accounts receivable and inventory. The increase in
accounts receivable in fiscal 1996 was due to revenue growth, including the
continued expansion in international operations relative to total operations
which typically have longer collection cycles. Days sales outstanding in
receivables were 54 days at June 30, 1996 compared to 40 days at June 30, 1995.
Days sales outstanding may continue to vary, due to, among other things, timing
of product shipments and international expansion. The increase in inventory was
primarily attributable to increasing inventory levels to meet desired
manufacturing lead times and anticipated demand for new product introductions.
 
     The Company used $119.7 million, $298.5 million and $222.3 million for
investing activities in fiscal 1996, fiscal 1995 and fiscal 1994, respectively.
The consumption of cash in fiscal 1996 was due to increases in property, plant
and equipment needed for increased levels of business and the Company's
information technology. The Company expects to spend additional cash related to
additional property, plant and equipment and information technology required to
support the Company's operations in fiscal 1997. Furthermore, the Company
acquired two companies in fiscal 1996, Performance Technology, Inc., for $12.6
million, and Armon Networking, Ltd., for $34.2 million, for the purpose of
entering new markets, including the Internet market. The major investing
activities in fiscal 1995 and fiscal 1994 were primarily attributable to capital
additions to support business operations.
 
     Financing activities provided $44.9 million, $34.3 million and $24.5
million in fiscal 1996, fiscal 1995 and fiscal 1994, respectively. The cash
generated from financing activities was primarily due to cash received in
connection with the issuance of stock under the Company's stock plans, which
resulted in net proceeds of $45.4 million, $34.0 million and $24.4 million,
respectively.
 
     A subsidiary of the Company has outstanding $110 million of convertible
subordinated debentures which bear interest of 5 1/4% per annum, payable
semi-annually, and mature in May 2003. The debentures are convertible at the
option of the holder into the Company's common stock at a conversion price of
$42.61 per share. The Company has reserved 2,581,725 shares of common stock for
the conversion of these debentures. Beginning May 1996, the debentures are
redeemable at the option of the Company, initially at approximately 103.7% and
at decreasing prices thereafter to 100% at maturity. To date, the Company's
management has made no decision whether to redeem the debentures.
 
                                       14

     The Company believes that it has the financial resources needed to meet
business requirements, including capital expenditures, working capital
requirements, the debt obligations outstanding and operating lease commitments
for facilities at least through the next twelve months.
 
RISK FACTORS THAT MAY AFFECT FUTURE RESULTS.
 
     As noted above, the foregoing discussion may include forward-looking
statements that involve risks and uncertainties. In addition, Bay Networks
identifies the following risk factors which could affect the Company's actual
results and cause actual results to differ materially from those in the
forward-looking statements.
 
     Risks Related to New Products.  The Company's future revenue is dependent
on its ability to successfully develop, manufacture and market products for
customers worldwide. In this regard, future growth is dependent on the Company's
ability to timely and successfully develop and introduce new products, establish
new distribution channels, develop affiliations with leading market participants
which facilitate product development and distribution, and market existing and
new products with service providers, resellers and channel partners, and others.
Also, future revenue may be affected in part by factors which influence the
business of the Company's direct and indirect resellers, such as the resellers'
organization structure, purchasing patterns and inventory levels.
 
     The Company believes that the markets for its products are characterized by
rapid rates of technological innovation for both hardware and software. There
can be no assurance that the Company's research and development efforts will
result in commercially successful new technology and products in the future. In
addition, as the technical complexity of new products increases, it may become
increasingly difficult to introduce new products quickly and according to
schedule.
 
     Risks Related to Recent Developments.  The Company recently announced an
internal reorganization and implemented a new information system which it
believes will better serve its customers and the market overall. There can be no
assurances that these actions will achieve the Company's objectives.
 
     Dependence on Personnel.  The Company's success depends upon the continued
contributions of its personnel, many of whom would be difficult to replace. The
success of the Company will depend on the ability of the Company to attract and
retain skilled employees. Changes in personnel, therefore, could adversely
affect operating results.
 
     Risks Related to Gross Margin.  The Company's gross margin percentage is a
function of the product mix sold in any period. Other factors such as unit
volumes, obsolescence of inventory, heightened price competition, changes in
channels of distribution, shortages in components due to timely supplies of
parts from vendors or ability to obtain items at reasonable prices, and
availability of skilled labor, also may continue to affect the cost of sales and
the fluctuation in gross margin percentages in future periods. In the past, the
Company has paid premiums to secure adequate supplies of components, and it
could become necessary to make such payments again in the future.
 
     Risks Related to Timing of Product Shipments.  One of the risks potentially
affecting the Company's operating results is the fact that a substantial portion
of the Company's revenue in any period may result from shipments during the
latter part of a period. Because the Company establishes its operating expense
level based on its operational goals, if shipments in any period do not meet
goals, net profits may be adversely affected.
 
     Risks Related to Backlog.  The Company has attempted to reduce its product
manufacturing lead times and its backlog of orders. To the extent that backlog
is reduced during any particular period, it could result in more variability and
less predictability in the Company's quarter to quarter revenue and operating
results. If manufacturing lead times are not reduced, the Company's customers
may cancel, or not place, orders if shorter lead times are available from other
manufacturers. In addition, the Company's ability to meet customer demand may
also be dependent on the ability of the Company to increase manufacturing levels
for new products to volumes required based on anticipated orders by the market.
 
                                       15
<PAGE>   17
 
     Risks Related to Intellectual Property Rights.  The Company currently
relies upon a combination of patents, copyrights, trademarks and trade secret
laws to establish and protect its proprietary rights in its products. The
Company maintains as proprietary the software and other portions of the
technology incorporated in its network management and other products, and may
license that technology to others as necessary. There can be no assurance that
the steps taken by the Company in this regard will be adequate to prevent
misappropriation of its technology or that the Company's competitors will not
independently develop technologies that are substantially equivalent or superior
to the Company's technology. In addition, the laws of some foreign countries do
not protect the Company's proprietary rights to the same extent as do the laws
of the United States. The Company has a number of patents and may apply for
additional patents. There can be no assurance that patents will issue from any
applications filed by the Company or that, if patents do issue, the claims will
be sufficiently broad to protect the technology invented by the Company. In
addition, no assurance can be given that any patents issued to the Company will
not be challenged, invalidated or circumvented or that the rights granted
thereunder will provide competitive advantages.
 
     Because of the existence of a large number of patents in the networking
field and the rapid rate of issuance of new patents or new standards that may
issue or to obtain important technology, it may be necessary for the Company to
enter into technology licenses from others. Such licenses could impact the
Company's operating results, and there is no assurance that the Company will be
able to license such technology.
 
     Risks Related to New Markets.  During 1996, the Company entered new
markets, including the remote access and Internet markets, primarily through the
acquisition of other businesses. The revenue or net profits from these new
markets and businesses has not been material in the past. At present, these new
markets are undeveloped and rapidly changing. If these markets do not develop,
or if the Company's strategies for these markets are unsuccessful, the Company's
operating results may be adversely affected.
 
     Revenue Fluctuations and Competition.  The data networking industry has
grown in the past few years, however, the Company's revenue may fluctuate year
over year or any quarter over quarter based on competition and customers waiting
for anticipated product introductions. The networking industry is highly
competitive and competition is expected to intensify and could adversely affect
the Company's future results. Networking and communications suppliers compete in
areas such as: conformity to existing and emerging industry standards;
interoperability with other networking products; the ability to run Ethernet,
token ring and FDDI networks on most common cabling systems; network management
capabilities; ease of use; scalability; price; performance; reliability; product
features; technical support; marketing expertise; and product innovation.
 
     There are many companies competing in various segments of the intelligent
hub, switching, router and remote access network markets. The Company's
principal competitors include Ascend Communications, Cabletron Systems, Inc.,
Cascade Communications, Cisco Systems, Inc., Digital Equipment Corporation, Fore
Systems, Inc., Hewlett-Packard Company, Inc., International Business Machines
Corporation and 3Com Corporation, among others. Several of the Company's
competitors have greater name recognition, more extensive engineering,
manufacturing and marketing capabilities, and greater financial, technological
and personnel resources than those available to the Company. In addition,
certain companies in the networking industry have expanded their product lines
or technologies in recent years as a result of acquisitions. Specifically, 3Com
Corporation acquired Chipcom Corporation and Cisco Systems, Inc. recently
acquired Stratacom, Inc. and announced its intention to acquire Telebit
Corporation, a manufacturer of digital modems. There can be no assurance that
the Company will be able to compete successfully in the future with existing or
new competitors.
 
     With industry standards established and new standards emerging, more
companies have developed standards-based products and have sought to compete on
the basis of price. Pressures from competitors offering lower priced products
could result in future price reductions for the Company's products.
 
     Risks Related to Acquisitions.  To implement its business plans, the
Company may make further acquisitions in the future. Acquisitions require
significant financial and management resources both at the time of the
transaction and during the process of integrating the newly acquired business
into the Company's
 
                                       16
<PAGE>   18
 
operations. The Company's operating results could be adversely affected if it is
unable to successfully integrate such new companies into its operations. Certain
acquisitions or strategic transactions may be subject to approval by the other
party's board or shareholders, domestic or foreign governmental agencies, or
other third parties. Accordingly, there is a risk that important acquisitions or
transactions could fail to be concluded as planned. Future acquisitions by the
Company could also result in issuances of equity securities or the rights
associated with the equity securities, which could potentially dilute earnings
per share. In addition, future acquisitions could result in the incurrence of
additional debt, taxes, or contingent liabilities, and amortization expenses
related to goodwill and other intangible assets. These factors could adversely
affect the Company's future operating results and financial position.
 
     Reliance on Resellers and Distributors.  VAR and distributor networks have
continued to represent an important part of the Company's overall sales and
distribution strategy. While the Company is not dependent on any single VAR or
distributor, the loss of, or changes in the relationship with or performance by,
several VARs or distributors nevertheless could have a material adverse effect
on the Company's revenue and operating results. The loss of, or changes in the
relationship with or performance by, one or more international distributors
could have a material adverse effect on the Company's revenue and operating
results.
 
     Risks Related to International Sales.  International sales may be an
increasingly important contributor to the Company's revenue and net profits. As
a result, operating results are increasingly affected by the risks of such
activities, including economic conditions in the international markets in which
the Company sells its products and political and economic instability,
fluctuations in currency exchange rates, changes in international regulatory
requirements, international staffing and employment issues, tariffs and other
trade barriers, import and export controls and the burden of complying with
foreign laws. Sales into developing nations may fluctuate to a greater extent
than sales to customers in developed nations, as those markets are only
beginning to adopt new technologies and establish purchasing practices. These
risks may adversely affect the Company's future operating results and financial
position.
 
     Risks Related to Government Regulations and Product Certification.  The
Company's operations are also subject to laws, regulations, government policies,
and product certification requirements worldwide. Changes in such laws,
regulations, policies, or requirements could affect the demand for the Company's
products or result in the need to modify products, which may involve substantial
costs or delays in sales and could have an adverse effect on the Company's
future operating results.
 
     Risks of Stock Volatility and Absence of Dividends.  In recent years, the
stock market in general and the market for technology stocks in particular,
including the Company's common stock, have experienced extreme price
fluctuations. There is a risk that stock price fluctuation could impact the
Company's operations. Changes in the price of the Company's common stock could
affect the Company's ability to successfully attract and retain qualified
personnel or complete necessary business combinations or other transactions in
the future. The Company has never paid any cash dividends on its capital stock,
and there can be no assurance that the Company will do so.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Basis of Presentation
 
     The consolidated financial statements include the accounts of Bay Networks,
Inc. (Bay Networks or the Company) and its subsidiaries. All significant
intercompany accounts and transactions have been eliminated.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
     Cash Equivalents, Fair Values of Financial Instruments & Concentration of
Credit Risk
 
     Financial instruments that potentially subject the Company to
concentrations of credit risk consist principally of cash equivalents,
investments and trade receivables.
 
     All of the Company's cash equivalents and investments are classified as
available-for-sale and are reported at fair value with material unrealized gains
and losses, if any, included in stockholders' equity. The fair value of
investments is based on quoted market prices. Realized gains and losses are
included in net interest income and other. Cash equivalents have original
maturities of three months or less. The Company has cash equivalents and
investments with various high quality institutions and, by policy, limits the
amount of credit exposure to any one institution.
 
     The Company sells its products to customers in diversified industries
worldwide. The Company performs on-going credit evaluations of its customers'
financial condition and generally does not require collateral. The Company
maintains reserves for potential credit losses, and such losses have been within
management's expectations and have not been material in any year. The Company's
trade receivables are derived from sales spread across various industries and
various geographical areas.
 
     Foreign Currency Translation
 
     The functional currency of each of the Company's international subsidiaries
is the foreign subsidiary's local currency. Assets and liabilities of the
Company's international operations are translated into U.S. dollars at exchange
rates in effect at the balance sheet date. Income and expense items are
translated at average exchange rates for the period. Accumulated net translation
adjustments were not material. Foreign exchange transaction gains and losses
were not material and are included in the results of operations.
 
     Bay Networks' international business is an important contributor to the
Company's revenue and net profits. However, the majority of Bay Networks'
international sales are denominated in the U.S. dollar, and an increase in the
value of the U.S. dollar relative to foreign currencies could make products sold
internationally less competitive. The operating expenses of Bay Networks'
overseas offices are paid in local currencies and are subject to the effect of
fluctuations in foreign currency exchange rates. The effect of foreign exchange
rate fluctuations did not significantly impact the Company's operating results.
Financial exposure may nonetheless result, primarily from the timing of
transactions and the movement of exchange rates.

     Warranty
 
     Upon shipment to its customers, the Company provides for the estimated cost
to repair or replace products to be returned under warranty. The Company's
warranty period is up to 12 months from the date of shipment for domestic sales
and up to 15 months from the date of shipment for international export sales.
 
     Revenue Recognition
 
     The Company recognizes revenue from product sales and accrues for estimated
returns at the time of shipment. Service revenue is recognized at the time
service is provided or ratably over the contractual service period.
 
     Advertising Costs
 
     Advertising costs are charged to operations as incurred. Advertising
expense was $18.2 million, $7.6 million and $8.4 million in 1996, 1995 and 1994,
respectively.
 
     Net Income per Share
 
     Net income per share is calculated using the weighted average number of
common shares and dilutive common share equivalents outstanding during the
period. Dilutive common share equivalents consist of stock options using the
treasury stock method.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     Stock Distribution
 
     On November 24, 1995, the Company effected a stock distribution in the form
of a three-for-two stock split to stockholders of record as of October 30, 1995.
All share and per share amounts applicable to prior periods have been
retroactively restated to reflect the effect of this split.
 
     Effect of New Accounting Standards
 
     In 1995, the Financial Accounting Standards Board (FASB) issued Statement
No. 121 (SFAS 121), Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of. The Company will adopt SFAS 121 in the
first quarter of fiscal year 1997 and, based on current circumstances, does not
believe the effect of adoption will be material.
 
     The Company accounts for its stock options and its employee stock purchase
plan in accordance with the provisions of the Accounting Principles Board
Opinion No. 25 (APB 25), Accounting for Stock Issued to Employees. In 1995, the
FASB issued Statement No. 123 (SFAS 123), Accounting for Stock-Based
Compensation. The Company intends to adopt the pro forma disclosure alternative
of SFAS 123 for the Company's fiscal year 1997. The adoption of SFAS 123 is not
expected to have a material effect on consolidated financial position, results
of operations, or cash flows.
 
     Reclassifications
 
     Certain reclassifications have been made to the 1995 and 1994 consolidated
financial statements to conform to the 1996 presentation.
 
2.  BUSINESS COMBINATIONS
 
     On October 21, 1994, SynOptics Communications, Inc. (SynOptics) and
Wellfleet Communications, Inc. (Wellfleet) effected a strategic combination of
the two companies through the merger of a wholly-owned subsidiary of Wellfleet
with and into SynOptics (the Combination). In connection with the Combination,
Wellfleet changed its name to Bay Networks, Inc. and issued 70,612,759 shares of
common stock for all the outstanding stock of SynOptics in a transaction
accounted for as a pooling of interests. The accompanying consolidated financial
statements are presented on a combined basis for all periods presented.
 
     In May 1995, Bay Networks acquired Centillion Networks, Inc. (Centillion)
and issued 5,353,275 shares of common stock for all the outstanding stock of
Centillion in a transaction accounted for as a pooling of interests. As the
results of operations and financial position of Centillion were not material to
Bay Networks' 1995 consolidated financial statements, the prior years' amounts
were not restated.
 
     In December 1995, Bay Networks acquired Xylogics, Inc. (Xylogics), in a
transaction accounted for as a pooling of interests. The Company issued
8,710,865 shares of common stock for all the outstanding stock of Xylogics and
reserved 1,655,275 shares of its common stock for issuance under Xylogics stock
option plans which the Company assumed in the acquisition. The accompanying
consolidated financial statements for prior periods have, accordingly, been
restated to reflect this transaction.

     Of the total amount for the year ended June 30, 1995, $61.1 million relates
to the Wellfleet/SynOptics combination and $2.3 million relates to the
Centillion acquisition. Of the total amount for the year ended June 30, 1996,
$16.1 million relates to the Xylogics acquisition and $5.9 million represents a
reversal of previously recorded merger related expenses in connection with the
prior year's transactions. Such reduction in the previous estimate was due
primarily to the usage of facilities which the Company had previously planned to

rent and severance related expenses to be paid principally over periods of up to
two years.
 
     The Company has acquired several smaller businesses, each of which has been

Networking, Ltd. for approximately $34.2 million in 1996; Scorpion Ltd. for
approximately $9.3 million in 1995; and Coral Network Corporation for
approximately $18.0 million in 1994. The purchase price of each acquired company
was allocated to the acquired assets and liabilities based on their estimated
fair values as of the date of respective acquisition. Amounts allocated to
developed technology, workforce and goodwill are being amortized on a
straight-line basis over a five year period. Amounts allocated to in-process
research and development of approximately $39.7 million, $6.7 million and $17.9
million in 1996, 1995 and 1994, respectively, were expensed upon the closing of
the respective transactions. Pro forma information has not been presented
because the effects of these acquisitions were not material to the Company's
consolidated financial position, results of operations, or cash flows.
 
     On June 16, 1996, Bay Networks signed a definitive agreement to acquire the
Digital Signal Processing (DSP) modem business of Penril DataComm Networks, Inc.
(Penril), a provider of advanced DSP-based modems and remote access products.
Under terms of the agreement, the Company will exchange $10 payable in the
Company's common stock according to an exchange value determined by averaging
the Company's closing stock prices over a specified period prior to closing, for
each share of Penril's common stock. (At June 6, 1996, Penril had 10,543,369
shares of common stock outstanding.) Immediately prior to the closing of this
transaction, the remaining non-DSP modem businesses of Penril will be spun off
to Penril stockholders. This acquisition is subject to regulatory approval and
Penril stockholders' approval. The acquisition will be accounted for as a
purchase. Based on preliminary estimates, the Company expects to allocate
approximately $60 million to $65 million to in-process research and development,
which will be charged to expense upon the closing of the transaction, currently
expected to be in the quarter ending December 31, 1996.

     Both gross unrealized gains and losses as of June 30, 1996 and 1995, and
realized gains and losses on sales of each type of security for the years ended
June 30, 1996 and 1995, were immaterial. At June 30, 1996 and 1995, the fair

of securities sold is based upon specific identification.
 
     Long-Term Debt
 
     A subsidiary of the Company has outstanding $110,000,000 of convertible
subordinated debentures which bear interest of 5 1/4% per annum, payable
semi-annually, and mature in May 2003. The debentures are convertible at the
option of the holder into the Company's common stock at a conversion price of
$42.61 per share. Beginning May 1996, the debentures are redeemable at the
option of the Company, initially at approximately 103.7% and at decreasing
prices thereafter to 100% at maturity. The fair value of these debentures is
estimated based on quoted market prices obtained from a third party for similar
debt and is approximately $99.7 million and $101.3 million as of June 30, 1996
and 1995, respectively. The Company has reserved 2,581,725 shares of common
stock for the conversion of these debentures. Interest expense, primarily
related to these debentures, was approximately $5.9 million, $6.0 million and
$5.9 million in 1996, 1995 and 1994, respectively.
 
4.  COMMITMENTS AND CONTINGENCIES
 
     Leases
 
     The Company leases its domestic and international facilities under
cancelable, non-cancelable and month-to-month operating leases. Rent expense was
approximately $27.5 million, $22.7 million and $18.4 million in 1996, 1995 and
1994, respectively.
 
     A subsidiary of the Company has a fifty percent interest in a limited
partnership which owns one of the Company's manufacturing facilities. The
Company leases this facility from the limited partnership. Included in the
operating lease commitments table below are $13.7 million related to this
facility.

     From time to time, as a normal incidence of the nature of the Company's
business, various claims, charges and litigation are asserted or commenced
against the Company. In the opinion of management, final judgments from such
claims, charges and litigation, if any, against the Company would not have a
material adverse effect on its consolidated financial position, results of

     Employee Stock Option Plans.  Bay Networks established a Stock Option Plan
in 1994 under which it authorized 30,000,000 shares of common stock for granting
of either incentive or non-qualified stock options and increased the authorized
shares to 41,700,000 in 1996. Exercisability, option price and other terms are
determined by the Board of Directors, but the option price shall not be less
than the fair market value of the stock at the date of grant. Shares of options
generally vest at the rate of 25% after one year from the date of grant, and
then ratably over the following 36 months. At June 30, 1996, 13,339,025 shares
of common stock were reserved for future grants.
 
     Pursuant to business combinations in 1995, the Company assumed stock option
plans under which options were generally exercisable upon grant and vested at
the rate of 25% after one year from the date of grant, and then ratably over the
following 36 months; however, those shares received upon exercise prior to
vesting were subject to repurchase by the Company. As of June 30, 1996, 60,222
shares were subject to repurchase.
 
     Additionally, on December 15, 1995, pursuant to the acquisition of
Xylogics, Bay Networks assumed 1,655,275 outstanding options originally issued
under various Xylogics stock option plans. The options generally vest at the
rate of 25% per year beginning one year from the date of grant.
 
     Outside Directors Stock Option Plans.  Bay Networks established an Outside
Directors Stock Option Plan in 1994 under which it authorized 750,000 shares of
the common stock pursuant to a fixed formula for granting of non-qualified stock
options to directors of the Company who are not employees of the Company
(Outside Directors) at exercise prices not less than the fair market value on
the date of grant. Upon initial election or appointment, an Outside Director
shall automatically receive an option to purchase 52,500 shares of common stock.
An Outside Director is granted an additional 15,000 shares of common stock
automatically on each of the second through seventh anniversary dates of his or
her initial grant. The options granted under the Directors Stock Option Plan
generally vest at a rate of 33 1/3% on the one year anniversary of the date of

     Employee Stock Purchase Plans.  Bay Networks has an Employee Stock Purchase
Plan (the Purchase Plan) under which 2,695,812 shares of common stock remain
available for future purchases. Each eligible employee may purchase shares of
common stock through the accumulation of payroll deductions of up to 10% of each
participating employee's gross wages not to exceed a maximum of $5,040 per
purchase period. The Purchase Plan authorizes the purchase of shares of common
stock at the end of semi-annual purchase periods beginning May 1 and November 1
of each year. The purchase price is an amount equal to 85% of its fair market
value determined as of the beginning of an offering period and the end of a
purchase period. In 1996 and 1995, employees purchased 696,712 shares and
613,070 shares and approximately $13.9 million and $8.2 million of proceeds were
recorded to stockholders' equity, respectively. The Purchase Plan will expire
upon either issuance of all shares reserved for issuance or at the discretion of
the Board of Directors. There are no plans to terminate the Purchase Plan at
this time.
 
     Both Wellfleet and SynOptics maintained employee stock purchase plans under
which eligible employees purchased common stock at a price equal to 85% of the
lower of the fair market values as of the beginning of an offering period and
the end of a purchase period. During 1994, 543,658 shares were issued under
these plans and approximately $7.7 million of proceeds were recorded to
stockholders' equity. Pursuant to the Combination, these plans were terminated.
 
     Stock Purchase Rights Plan.  Under a preferred stock purchase rights plan,
adopted by the Company's Board of Directors on February 7, 1995, stockholders of
the Company received rights to purchase stock in the Company, or in an acquirer
of the Company, at a discounted price, under certain circumstances and in the
event of particular hostile efforts to acquire control of the Company. The
rights may be redeemed pursuant to the plan by the Board of Directors. The
rights expire on February 7, 2005.
 
6.  EMPLOYEE BENEFIT PLAN
 
     The Company maintains the Bay Networks, Inc. 401(k) Plan (the Plan) to
provide retirement benefits for its employees. As allowed under Section 401(k)
of the Internal Revenue Code, the Plan provides tax deferred salary deductions
for eligible employees. Eligible employees may contribute from 1% to 15% of
their annual compensation to the Plan, limited to a maximum amount as set by the
Internal Revenue Service. The Company will make matching contributions unless
business conditions dictate otherwise, pursuant to a fixed

              WHEREAS, a Plan and Agreement of Merger dated as of June 16, 1996,

                   fractional Merger Shares that would otherwise be issued, each
                   former Company Stockholder that would have been entitled to
                   receive a fractional Merger Share shall, upon proper
                   surrender of such person's Certificates, receive a cash
                   payment equal to the Buyer Stock Market Price, multiplied by

                   after Requisite Stockholder Approval) as provided below:

                       (a) the Parties may terminate this

                         (b) the Buyer may terminate this Agreement by giving

                   breach, and the Company may terminate this Agreement by
                   giving written notice to the Buyer and the Transitory

                   breach is not remedied within 10 days of delivery of written
                   notice thereof;

                         (c) any Party may terminate this Agreement by giving

                   receive the Requisite Stockholder Approval;

                         (d) the Buyer may terminate this Agreement by giving

                   occurred (i) on or before November 25, 1996, by reason of the
                   failure of any condition precedent under Section 5.1 or 5.2
                   hereof (unless the failure results primarily from a breach by
                   the Buyer or the Transitory Subsidiary of any representation,
                   warranty or covenant contained in this Agreement);

                         (e) the Company may terminate this Agreement by giving
                   written notice to the Buyer and the Transitory Subsidiary if
                   the Closing shall not have occurred (i) on or before November
                   25, 1996, by reason of the failure of any condition precedent
                   under Section 5.1 or 5.3 hereof (unless the failure results
                   primarily from a breach by the Company of any representation,
                   warranty or covenant contained in this Agreement); or

                         (f) any Party may terminate this Agreement if the Board
                   of Directors of the Company shall have withdrawn or modified
                   in a manner adverse to the Buyer its approval or
                   recommendation to the Company Stockholders of this Agreement
                   or the Merger or shall have approved or recommended to the
                   Company Stockholders that they accept the terms of any
                   Acquisition Proposal or shall have resolved to take any of
                   the foregoing actions; provided, however, that reasonable
                   delay required to comply with the Company Board Fiduciary
                   Duties shall not be deemed to be a withdrawal or a
                   modification adverse to the Buyer.

              4.   Replacement of Exhibit C to the Merger Agreement.
         Exhibit C to the Merger Agreement is replaced in its entirety by
         Exhibit C attached hereto.

         inconsistency between the provisions of the Merger Agreement and
         the applicable provisions of this Agreement, the provisions of

         Merger Agreement shall remain in full force and effect.

              6. Successors and Assigns; Governing Law. Subject to the Merger
         Agreement as amended hereby, this Agreement shall inure to the benefit
         of and bind the respective heirs, personal representatives, successors
         and assigns of the parties hereto and shall be governed by and
         construed in accordance with the internal laws (and not the law of
         conflicts) of the State of Delaware.

              7.   Severability; Modifications.  Should one or more of the
         provisions of this Agreement be determined by a court of law to be
         illegal or unenforceable, the other provisions shall nevertheless
         remain effective and shall be enforceable.  This Agreement shall
         not be modified without the prior consent of each of the Parties.

              8. Execution in Counterparts. This Agreement may be executed in
         two or more counterparts, each of which shall be deemed an original but
         all of which together shall constitute one and the same instrument.
         This Agreement, once executed, may be delivered to either party through
         the use of facsimile transmission. In this regard, any and all
         signatures of the parties appearing on any facsimile copies of this
         Agreement shall be deemed, unless otherwise proved, the lawful and
         valid signature of the executing party.

              IN WITNESS WHEREOF, the parties hereto have executed this
         Agreement as of the date set forth below.

              Effective date of this Agreement:  August 5, 1996.

                            INDEMNIFICATION AGREEMENT


              This Indemnification Agreement ("Agreement") is made and entered
         into as of the _____ day of ______________, 1996 between Penril
         DataComm Networks, Inc., a Delaware corporation ("Penril"), and [the
         Spin-off Company], a Delaware corporation ("Newsub").

              WHEREAS, Penril formed Newsub as a wholly-owned subsidiary and, by
         action of its Board of Directors, contributed or will contribute
         certain assets (the "Spun-off Assets"), and assigned or will assign
         certain liabilities (the "Spun-off Liabilities") to Newsub and Newsub
         accepted or will accept the Spun-off Assets and assumed or will assume
         the Spun-off Liabilities;

              WHEREAS, Penril, by action of its Board of Directors, as ratified
         by its stockholders, will distribute all of the outstanding capital
         stock of Newsub (the "Newsub Stock") to such stockholders in the form
         of a dividend (the "Distribution");

              WHEREAS, Penril, Beta, Inc., a Delaware corporation ("Buyer"), and
         Transitory Subsidiary, wholly-owned subsidiary of Buyer, have entered
         into an Plan and Agreement of Merger dated as of June 16, 1996, and as
         amended on August 5, 1996 (the "Merger Agreement"), pursuant to which,
         following the Distribution, Penril will become a wholly-owned
         subsidiary of Buyer and the stockholders of Penril will receive shares
         of Buyer stock in exchange for shares of Penril stock (the "Merger");

              WHEREAS, until the Distribution, Penril owns 100% of the
         issued and outstanding Newsub Stock;

              WHEREAS, as consideration for, and in connection with, Penril
         making the aforementioned capital contribution to Newsub, Newsub agrees

         by Penril, and Penril agrees to indemnify Newsub for claims, costs,
         damages or liabilities incurred by Newsub, on the terms, and subject to
         the conditions, as set forth below.

              NOW, THEREFORE, in consideration of the foregoing premises and the

              directly or indirectly, (including, without limitation, reasonable
              legal fees and expenses) resulting from or attributable to (i) the
              operation of Newsub from and after the Distribution; (ii) any
              claim, suit or other type of proceeding based upon, arising out of
              or in connection with the operation of Penril prior to the Merger
              other than those based upon, arising out of or in connection with

              to approval of the Merger and other transactions related to the
              Merger, or the tax consequences of the Distribution, but
              including, without limitation, any claim, suit or other type of
              proceeding based upon, arising out of or in connection with the

              than those set forth on Schedule 2.20 to the Merger Agreement; and
              (iv) any claim, suit or other type of proceeding based upon,
              arising out of or in connection with any information concerning
              Newsub in the Registration Statement (as defined in the Merger
              Agreement) that was furnished by Penril and/or Newsub for
              inclusion in the Registration Statement or any part thereof. In
              furtherance thereof, Newsub acknowledges and agrees that (ii)
              above includes, but is not limited to, all suits, actions or
              administrative hearings existing on the date hereof to which
              Penril is a party (or which have been assigned by Penril to Newsub
              and assumed by Newsub) other than those based upon, arising out of
              or in connection with the Modem Business (collectively, the
              "Newsub Existing Litigation", as listed on Exhibit A hereto). This
              Agreement will constitute notice, in accordance with Paragraph 2
              hereof, of Newsub's election to conduct the defense (or to
              prosecute, as the case may be) of all claims in connection

              with the Newsub Existing Litigation. Other than certain rights
              retained pursuant to Paragraph 2 hereof Penril acknowledges and
              agrees that Newsub will have all rights to, and title and interest
              in any such claim, suit or proceeding for which Newsub is
              providing indemnification.

                   (b) Penril will indemnify and save harmless Newsub and its
              directors, officers, employees, agents and/or affiliates (each, a
              "Penril Indemnified Party" and, together with each Newsub
              Indemnified Party, without distinction, an "Indemnified Party")
              from any and all Claims incurred or suffered, directly or
              indirectly, (including, without limitation, reasonable legal fees
              and expenses) resulting from or attributable to (i) the operation
              of Penril from and after the Distribution; (ii) any claim, suit or
              other type of proceeding based upon, arising out of or in
              connection with the operation of the Modem Business prior to the
              Merger; and (iii) any claim, suit or other type of proceeding
              relating to the Merger, the Merger Agreement, the solicitation of
              proxies relating to approval of the Merger and the other
              transactions related to the Merger other than those based upon,
              arising out of or in connection with the Newsub Registration
              Statement on Form S-1 filed with the Securities and Exchange
              Commission to register the Newsub Stock in connection with the
              Distribution or any information concerning Newsub in the
              Registration Statement that was furnished by Penril and/or Newsub
              for inclusion in the Registration Statement. In furtherance
              thereof, Penril acknowledges and agrees that (ii) above includes,
              but is not limited to, all suits, actions or administrative
              hearings existing on the date hereof to which Penril is a party
              (none of which have been assigned by Penril to Newsub or assumed
              by Newsub) which are based upon, arising out of or in connection
              with the Modem Business (collectively, the "Penril Retained
              Existing Litigation", as listed on Exhibit B hereto, and, together
              with the Newsub Existing Litigation, the "Existing Litigation").
              This Agreement will constitute notice, in accordance with
              Paragraph 2 hereof, of Penril's election to conduct the defense
              (or to prosecute, as the case may be) of all claims in connection
              with the Penril Retained Existing Litigation. Other than certain
              rights retained pursuant to Paragraph 2 hereof Newsub acknowledges
              and agrees that Penril will have all rights to, and title and
              interest in any such claim, suit or proceeding for which Penril is
              providing indemnification.

              2.   Defense of Claim.

                   (a) In the event an Indemnified Party receives notice of any
              claim asserted or any action or administrative or other proceeding
              commenced in respect of a Claim for which indemnity may be
              properly sought under this Agreement against Newsub or Penril, as
              the case may be (the "Indemnifying Party"), the Indemnified Party
              shall give notice in writing to the Indemnifying Party within
              thirty (30) days of its receipt of such notice. Within thirty (30)
              days after the earlier of (a) receipt by the Indemnifying Party of
              such notice from the Indemnified Party, or (b) receipt of actual
              notice by the Indemnifying Party from sources other than the
              Indemnified Party, the Indemnifying Party may give the Indemnified
              Party written notice of its election to conduct the defense of
              such claim, action or proceeding at its own expense. If the
              Indemnifying Party has given the Indemnified Party such notice of
              election to conduct the defense, the Indemnifying Party may
              conduct the defense at its expense, but the Indemnified Party
              shall nevertheless have the right to participate in the defense,
              provided such participation is solely at the expense of the
              Indemnified Party, without a right of further reimbursement. If
              the Indemnifying Party has not so notified the Indemnified Party
              in writing within the time period provided above of its election
              to conduct the defense of such Claim, the Indemnified Party may,
              but need not, conduct, at the Indemnifying Party's expense, the
              defense of such claim, action or proceeding. The Indemnified Party
              may at any time notify the Indemnifying Party of its intention to
              settle, compromise or satisfy any such claim, action or proceeding
              (the defense of which the Indemnifying Party has not previously
              elected to conduct) and, with the prior written consent of the
              Indemnified Party (which consent will not be unreasonably
              withheld), may make such settlement, compromise or satisfaction,
              at the Indemnifying Party's expense, provided, however, that the
              Indemnifying Party may make such settlement, compromise or
              satisfaction without the prior written consent of the Indemnified
              Party if such settlement, compromise or satisfaction constitutes a
              release of the Indemnified Party in respect of such Claim.

                   (b) Any settlement, compromise or satisfaction, or any final
              judgment or decree entered in, any Claim or Existing Litigation
              defended in accordance with the provisions of this Paragraph 2
              shall be final and binding on the parties hereto.

<PAGE>   10
                   (c) The Indemnified Party and the Indemnifying Party shall
              use all reasonable efforts to cooperate fully with respect to the
              defense of any Claim or Existing Litigation in accordance with the
              provisions of this Paragraph 2.

              3. Notice. All notices and other communications required or
         permitted to be given under this Indemnification Agreement shall be
         dated and in writing and shall be deemed to have been duly given when
         (a) personally delivered, (b) upon delivery of a telephonic facsimile
         transmission with a confirmed telephonic transmission answered back,
         (c) three days after being deposited in the United States mail,
         registered or certified, return receipt requested, postage prepaid, or
         (d) one day after having been dispatched by a nationally recognized
         overnight courier service, addressed to the party or parties to this
         Agreement to whom it is directed:

              If to Penril:

         or to such other address as may be designated by a party hereto by
         notice delivered to the other parties.

              4. Cooperation. In connection with any Claim that is the subject
         of indemnification, each party shall afford to the Indemnifying Party
         and its accountants, counsel and other designated representatives
         reasonable access during normal business hours to all records, books,
         contracts, instruments, computer data and other information insofar as
         such access is reasonably required by the indemnifying party in
         connection with the defense of any Claim pursuant to Paragraph 2
         hereof. In addition, each party shall use reasonable efforts to make
         available to the Indemnifying Party, upon written request, its
         officers, directors, employees and agents as witnesses to the extent
         that any such person may reasonably be required in connection with the
         defense or prosecution of any Claim.

              5. Waiver. The waiver by any party hereto of the breach of any
         provision of this Agreement shall not operate or be construed as a
         waiver of any preceding or succeeding breach and no failure by any
         party to exercise any right or privilege hereunder shall be deemed a
         waiver of such party's rights or privileges or shall be deemed a waiver
         of such party's rights hereunder to exercise the same at any subsequent
         time or times.

              6.   Amendment.  This Agreement may be amended, modified or
         supplemented only by written instrument executed by the party
         against whom enforcement is sought.

              7.   Governing Law.  This Agreement shall be governed by and
         construed in accordance with the internal laws of the State of
         Delaware.

              8. Severability. The invalidity, illegality or unenforceability of
         one or more of the provisions of this Agreement in any jurisdiction
         shall not affect the validity, legality or enforceability of the
         remainder of this Agreement in such jurisdiction or the validity,
         legality and enforceability of this Agreement, including any such
         provision, in any other jurisdiction, it being intended that all rights
         and obligations of the parties hereunder shall be enforceable to the
         fullest extent permitted by law.

              9.   Counterparts.  This Agreement may be executed in any
         number of counterparts, each of which shall be deemed to be an
         original, but all of which together shall constitute one and the
         same instrument.

              10.  Succession and Assignment.  This Agreement shall be
         binding upon and inure to the benefit of the parties hereto, and
         the Indemnified Parties and each of their respective successors
         and assigns.

         copies of such software in the operation of the Products.

                   (b) Licensee agrees not to copy or reproduce any of such

         Patents and use the Licensed Technology to its full potential. Such
         training and assistance shall be rendered by Licensor at no expense to

         parties hereto shall from time to time determine whether particular
         training and assistance shall be rendered at Licensor's facilities or
         at Licensee's facilities. Travel costs, lodging and all related
         expenses incurred by one party in connection with sending its employees
         or permitted sublicensees to the other party's location shall be paid
         in full by the party sending such individuals.

              3.4 Evaluations. Licensor shall provide Licensee free of charge
         with evaluations of Licensee's manufacturing, assembly, service,
         testing, installation and technical proposals; provided, however, that

         the term of this Agreement in rendering such evaluations to Licensee.
         Licensor shall use its best efforts to deliver each evaluation to
         Licensee within ten (10) days after Licensee's request of such

         servicing of the Products; provided, however, that Licensor shall not
         be required to devote more than 80 man-hours during the term of this
         Agreement in responding to such written inquiries.

              3.6 Locating Sources for Components. Licensor shall use its best
         efforts, free of charge, to identify suppliers of components, parts,
         tools and test equipment for Products, and to then assist Licensee in
         negotiating supply agreements with such suppliers; provided, however,
         that Licensor shall not be required to devote more than 80 man-hours
         during the term of this Agreement in assisting Licensee pursuant to
         this provision.

              3.7  Additional Services.

                   (a) Licensor shall use its reasonable efforts to provide
         Licensee with any and all additional assistance reasonably requested by
         Licensee, including without limitation: producing technical, sales,
         advertising and other reports and information for Licensee which
         Licensee believes might be useful in selling the Products manufactured
         hereunder; and assisting Licensee in attempting to obtain from third
         parties technical information, drawings, plans, specifications and
         other data which are not proprietary to Licensor and which Licensor
         does not otherwise have


                                         -5-
<PAGE>   18
         the right to use, in order to enable Licensee to respond to requests of
         any potential customer.

                   (b) Licensor shall bill Licensee for any such services not
         expressly provided free of charge in Section 2.2(b) (Use of Technical
         Information) or in one of the earlier provisions of this Article 3 at
         prices to be agreed in advance by the parties hereto. In all cases the
         prices charged by Licensor for the services that it provides to
         Licensee shall not exceed the prices that it charges its best customer
         or licensee, as the case may be, for the same or similar services, if
         any. Licensor shall not commence performance of any part of any
         services hereunder until such prices are established in writing by the
         parties hereto.

         4.   COMPENSATION PAYABLE TO LICENSOR.

              In consideration of the rights granted to Licensee with respect to
         the Licensed Technology and for the services to be rendered by Licensor
         under this Agreement during the six months term, Licensee shall pay
         Licensor simultaneously with the execution of this Agreement the sum of
         Four Million Five Hundred Thousand Dollars ($4,500,000.00) in
         immediately available funds.

         5.   INVENTIONS.

              If Licensor formulates, makes or conceives a patentable invention
         or develops any other intellectual property rights which constitutes a
         modification and/or improvement of a Product, Licensor may apply, at
         its or his own expense and discretion, for appropriate patent and other
         intellectual property right registrations of such invention or rights
         in any and all jurisdictions. In each jurisdiction where Licensor does
         not apply for such patent or registration within ninety (90) days after
         having formulated, made or conceived and reduced to practice such
         patentable invention or developed such right and after notice from
         Licensee to Licensor of Licensee's desire to have such application or
         registration made, then Licensee may either: (i) apply for such patent
         or registration in such jurisdiction, at its own expense; or (ii)
         request Licensor to apply for such patent or registration in such
         jurisdiction and then assign all of its or his rights in such
         applications to Licensee, all at Licensee's expense. Licensor shall, at
         the request of the Licensee, both during and after the term of this
         Agreement, execute such documents and render such assistance as may be
         appropriate to enable Licensee to maintain or obtain registrations of
         patents or intellectual property rights in any jurisdiction in
         accordance with this Article 5.

         6.   CONFIDENTIAL INFORMATION.

              6.1  Confidentiality Maintained.  Each party agrees that the
         other party hereto has a proprietary interest in its Confidential
         Information.  During the term of this Agreement and for a period of
         three years thereafter, all disclosures of Confidential Information

         to the receiving party, its agents and employees shall be held in
         strict confidence by such receiving party, its agents and employees,
         and such receiving party shall disclose the Confidential Information
         only to those of its agents and employees to whom it is necessary in
         order properly to carry out their duties as limited by the terms and
         conditions hereof. During the term of this Agreement and for a period
         of three years thereafter the receiving party shall not use the
         Confidential Information except for the purposes of exercising its
         rights and carrying out its duties hereunder. Upon the expiration or
         earlier termination of this Agreement, each party shall return to the
         other all Confidential Information and all copies thereof, and shall
         not at any time thereafter use any of such Confidential Information for
         any purpose. The provisions of this Section 6.1 shall also apply to any
         consultants or subcontractors during the term of this Agreement and for
         three years thereafter that the receiving party may engage in
         connection with its obligations under this Agreement. Before providing
         any Confidential Information to any such consultant or subcontractor,
         the receiving party shall obtain a signed undertaking in which such
         consultant or subcontractor agrees to be bound by and comply with terms
         substantially equivalent to and to the same effect as this Article 6.

              6.2 Liability for Disclosure. Notwithstanding anything contained
         in this Agreement to the contrary, neither party shall be liable for a
         disclosure of the other party's Confidential Information if the
         information so disclosed:

                   (a)  was in the public domain at the time it was dis-
         closed by the disclosing party to the receiving party; or

                   (b)  was known to or contained in the records of the 
         receiving party from a source other than the disclosing party at the 
         time of disclosure by the disclosing party to the receiving party and 
         can be so demonstrated; or

                   (c)  was independently developed by the receiving party
         and is so demonstrated promptly upon receipt of the documentation
         and technology by the receiving party; or

                   (d)  becomes known to the receiving party from a source other
         than the disclosing party without breach of this Agreement by the
         receiving party and can be so demonstrated; or

                   (e)  if in writing, was not identified as Confidential
         Information in accordance with Section 1.2 (Definition of
         Confidential Information) hereof; or

                   (f)  must be disclosed pursuant to a contract or subcon-
         tract with a governmental agency in order to obtain/retain a
         procurement contract; or


                                         -7-

                   (g) was disclosed pursuant to court order or as otherwise
         compelled by law.

                          PLAN AND AGREEMENT OF MERGER


              This Plan and Agreement of Merger entered into as of June 16, 1996
         by and among Bay Networks, Inc., a Delaware corporation (the "Buyer"),
         Beta Acquisition Corp., a Delaware corporation and a wholly-owned
         subsidiary of the Buyer (the "Transitory Subsidiary"), and Penril
         DataComm Networks, Inc., a Delaware corporation (the "Company"). The
         Buyer, the Transitory Subsidiary and the Company are referred to
         collectively in this Agreement as the "Parties".

              This Agreement contemplates a merger of the Transitory Subsidiary
         into the Company, which merger will qualify as a tax-free
         reorganization described in Section 368(a)(1)(B) of the Internal
         Revenue Code of 1986, as amended (the "Code"). In such merger, the
         stockholders of the Company will receive solely voting capital stock of
         the Buyer in exchange for their capital stock of the Company.

              The Parties acknowledge that in the event that the transactions
         contemplated by this Agreement are not consummated, the Company would
         experience a substantial loss and hardship; therefore, to minimize the
         potential for such (i) failure to consummate the transactions and (ii)
         loss and hardship, the Parties have knowingly agreed not to include in
         this Agreement many otherwise normal conditions to closing the
         transaction, including but not limited to, a condition that there shall
         be no material adverse change prior to the Effective Time (as defined
         below) to the Company, its business, financial condition, results of
         operations, or prospects, to the Company's industry or to the general
         business conditions.

              Now, therefore, in consideration of the representations,
         warranties and covenants in this Agreement contained, the Parties agree
         as follows.

                                    ARTICLE I

                                   THE MERGER

              1.1 The Merger. Upon and subject to the terms and conditions of
         this Agreement, the Transitory Subsidiary shall merge with and into the
         Company (with such merger referred to in this Agreement as the
         "Merger") at the Effective Time (as defined below). From and after the
         Effective Time, the separate corporate
<PAGE>   31
         existence of the Transitory Subsidiary shall cease and the Company
         shall continue as the surviving corporation in the Merger (the
         "Surviving Corporation"). The "Effective Time" shall be the time at
         which the Company and the Transitory Subsidiary file the certificate of
         merger or other appropriate documents prepared and executed in
         accordance with the relevant provisions of the Delaware General
         Corporation Law (the "Certificate of Merger") with the Secretary of
         State of the State of Delaware. The Merger shall have the effects set
         forth in Section 259 of the Delaware General Corporation Law.

              1.2 The Closing. The closing of the transactions contemplated by
         this Agreement (the "Closing") shall take place at a mutually agreed
         upon location, commencing at 9:00 a.m. local time on a mutually
         agreeable date as soon as practicable after the date on which all of
         the conditions to the obligations of the Parties to consummate the
         transactions contemplated by this Agreement have been satisfied or
         waived (the "Closing Date"), but in no event later than 150 days from
         the date hereof.

              1.3 Actions at the Closing. At the Closing, (a) the Company shall
         deliver to the Buyer and the Transitory Subsidiary the various
         certificates, instruments and documents referred to in Section 5.2, (b)
         the Buyer and the Transitory Subsidiary shall deliver to the Company
         the various certificates, instruments and documents referred to in
         Section 5.3, (c) the Company and the Transitory Subsidiary shall file
         with the Secretary of State of the State of Delaware the Certificate of
         Merger, and (d) the Buyer shall deliver a certificate for the Merger
         Shares (as defined below) to a bank, trust company or other entity
         reasonably satisfactory to the Company appointed by the Buyer to act as
         the exchange agent (the "Exchange Agent") in accordance with Section 
         1.7.

              1.4 Additional Action. The Surviving Corporation may, at any time
         after the Effective Time, take any action, including executing and
         delivering any document, in the name and on behalf of either the
         Company or the Transitory Subsidiary, in order to consummate the
         transactions contemplated by this Agreement.

              1.5 Conversion of Shares. At the Effective Time, by virtue of the
         Merger and without any action on the part of any Party or the holder of
         any of the following securities:

                   (a) Each share of common stock, $0.01 par value per share, of
         the Company ("Company Shares") issued and outstanding immediately prior
         to the Effective Time (other than Company Shares owned beneficially by
         the Buyer or the Transitory Subsidiary,


                                       -2-
<PAGE>   32
         Dissenting Shares (as defined below) and Company Shares held in the
         Company's treasury) shall be converted into and represent the right to
         receive (subject to the provisions of Section 1.9) such number of
         shares of common stock, $0.01 par value per share, of the Buyer ("Buyer
         Common Stock") as is equal to the Conversion Ratio (as defined below).
         The "Conversion Ratio" shall mean the number determined by dividing (i)
         $10.00 (ii) by the Buyer Stock Market Price. The "Buyer Stock Market
         Price" shall mean the average of the closing prices of the Buyer's
         Common Stock on the New York Stock Exchange (the "NYSE") five (5)
         consecutive trading days immediately preceding the second business day
         immediately preceding to the Closing Date. Stockholders of record of
         the Company ("Company Stockholders") shall be entitled to receive
         immediately all of the shares of Buyer Common Stock into which their
         Company Shares were converted pursuant to this Section 1.5(a) (the
         "Merger Shares").

                   (b) Each Company Share held in the Company's treasury
         immediately prior to the Effective Time and each Company Share owned
         beneficially by the Buyer or the Transitory Subsidiary shall be
         cancelled and retired without payment of any consideration therefor.

                   (c) Each share of common stock, $0.01 par value per share, of
         the Transitory Subsidiary issued and outstanding immediately prior to
         the Effective Time shall be converted into and thereafter evidence one
         share of common stock, $0.01 par value per share, of the Surviving
         Corporation.

              1.6  Dissenting Shares.

                   (a) For purposes of this Agreement, "Dissenting Shares" means
         Company Shares held as of the Effective Time by a Company Stockholder
         who has not voted such Company Shares in favor of the adoption of this
         Agreement and the Merger and with respect to which appraisal shall have
         been duly demanded and perfected in accordance with Section 262 of the
         Delaware General Corporation Law and not effectively withdrawn or
         forfeited prior to the Effective Time. Dissenting Shares shall not be
         converted into or represent the right to receive Merger Shares, unless
         such Company Stockholder shall have forfeited his right to appraisal
         under the Delaware General Corporation Law or withdrawn, with the
         consent of the Company, his demand for appraisal. If such Company
         Stockholder has so forfeited or withdrawn his right to appraisal of
         Dissenting Shares, then (i) as of the occurrence of such event, such
         holder's Dissenting Shares shall cease to be Dissenting Shares and
         shall be converted into and represent the right to receive the Merger
         Shares issuable in respect of such Company Shares pursuant to Section 
         1.5(a), and (ii) promptly following the


                                       -3-
<PAGE>   33
         occurrence of such event, the Buyer shall deliver to the Exchange Agent
         a certificate representing the Merger Shares to which such holder is
         entitled pursuant to Section 1.5(a).

                   (b) The Company shall give the Buyer (i) prompt notice of any
         written demands for appraisal of any Company Shares, withdrawals of
         such demands, and any other instruments that relate to such demands
         received by the Company and (ii) the opportunity to direct all
         negotiations and proceedings with respect to demands for appraisal
         under the Delaware General Corporation Law. The Company shall not,
         except with the prior written consent of the Buyer, make any payment
         with respect to any demands for appraisal of Company Shares or offer to
         settle or settle any such demands.

              1.7  Exchange of Shares

                   (a) Prior to the Effective Time, the Buyer shall appoint the
         Exchange Agent to effect the exchange for the Merger Shares of
         certificates that, immediately prior to the Effective Time, represented
         Company Shares converted into Merger Shares pursuant to Section 1.5
         (including any Company Shares referred to in the last sentence of
         Section 1.6(a)) ("Certificates"). On the Closing Date, the Buyer shall
         deliver to the Exchange Agent, in trust for the benefit of holders of
         Certificates, a stock certificate (issued in the name of the Exchange
         Agent or its nominee) representing the Merger Shares, as described in
         Section 1.5(a). As soon as practicable after the Effective Time, the
         Buyer shall cause the Exchange Agent to send a notice and a transmittal
         form to each holder of a Certificate (other than those surrendered and
         paid for at the Closing) advising such holder of the effectiveness of
         the Merger and the procedure for surrendering to the Exchange Agent
         such Certificate in exchange for the Merger Shares issuable pursuant to
         Section 1.5(a). Each holder of a Certificate, upon proper surrender
         thereof to the Exchange Agent in accordance with the instructions in
         such notice, shall be entitled to receive in exchange therefor (subject
         to any taxes required to be withheld) the Merger Shares issuable
         pursuant to Section 1.5(a). Until properly surrendered, each such
         Certificate shall be deemed for all purposes to evidence only the right
         to receive the Merger Shares issuable pursuant to Section 1.5(a).
         Holders of Certificates shall not be entitled to receive certificates
         for the Merger Shares to which they would otherwise be entitled until
         such Certificates are properly surrendered.

                   (b) If any Merger Shares are to be issued in the name of a
         person other than the person in whose name the Certificate surrendered
         in exchange therefor is registered, it shall be a condition to the
         issuance of such Merger Shares that (i) the Certificate so surrendered
         shall be transferable, and shall be


                                       -4-
<PAGE>   34
         properly assigned, endorsed or accompanied by appropriate stock powers,
         (ii) such transfer shall otherwise be proper and (iii) the person
         requesting such transfer shall pay to the Exchange Agent any transfer
         or other taxes payable by reason of the foregoing or establish to the
         satisfaction of the Exchange Agent that such taxes have been paid or
         are not required to be paid. Notwithstanding the foregoing, neither the
         Exchange Agent nor any Party shall be liable to a holder of Company
         Shares for any Merger Shares issuable to such holder pursuant to
         Section 1.5(a) that are delivered to a public official pursuant to
         applicable abandoned property, escheat or similar laws.

                   (c) In the event any Certificate shall have been lost, stolen
         or destroyed, upon the making of an affidavit of that fact by the
         person claiming such Certificate to be lost, stolen or destroyed, the
         Buyer shall issue in exchange for such lost, stolen or destroyed
         Certificate the Merger Shares issuable in exchange therefor pursuant to
         Section 1.5(a). The Board of Directors of the Buyer may, in its
         discretion and as a condition precedent to the issuance thereof,
         require the owner of such lost, stolen or destroyed Certificate to give
         the Buyer a bond in such sum as it may reasonably direct as indemnity
         against any claim that may be made against the Buyer with respect to
         the Certificate alleged to have been lost, stolen or destroyed.

                   (d) Promptly following the date which is six months after the
         Closing Date, the Exchange Agent shall return to the Buyer all Merger
         Shares in its possession, and the Exchange Agent's duties shall
         terminate. Thereafter, each holder of a Certificate may surrender such
         Certificate to the Buyer and, subject to applicable abandoned property,
         escheat and similar laws, receive in exchange therefor the Merger
         Shares issuable with respect thereto pursuant to Section 1.5(a).

              1.8 Dividends. No dividends or other distributions that are
         payable to the holders of record of Buyer Common Stock as of a date on
         or after the Closing Date shall be paid to former Company Stockholders
         entitled by reason of the Merger to receive Merger Shares until such
         holders surrender their Certificates in accordance with Section 1.7.
         Upon such surrender, the Buyer shall pay or deliver to the persons in
         whose name the certificates representing such Merger Shares are issued
         any dividends or other distributions that are payable to the holders of
         record of Buyer Common Stock as of a date on or after the Closing Date
         and which were paid or delivered between the Effective Time and the
         time of such surrender; provided that no such person shall be entitled
         to receive any interest on such dividends or other distributions.

              1.9 Fractional Shares. No certificates or scrip representing
         fractional Merger Shares shall be issued to former Company Stockholders
         upon the surrender for exchange of Certificates, and such former
         Company Stockholders shall not be entitled to any voting rights, rights
         to receive any dividends or distributions or other rights as a
         stockholder of the Buyer with respect to any fractional Merger Shares
         that would otherwise be issued to such former Company Stockholders. In
         lieu of any fractional Merger Shares that would otherwise be issued,
         each former Company Stockholder that would have been entitled to
         receive a fractional Merger Share shall, upon proper surrender of such
         person's Certificates, receive a cash payment equal to the closing
         price per share of the Buyer Common Stock on the NYSE, on the business
         day immediately preceding the business day prior to the Closing Date,
         multiplied by the fraction of a share that such Company Stockholder
         would otherwise be entitled to receive. The fractional share interests
         of each Company Stockholder will be aggregated, and no Company
         Stockholder will receive cash in an amount equal to or greater than the
         value of one full share of Buyer Common Stock.

              1.10 Options and Rights.

                   (a) As of the Effective Time, all obligations of the Company
         with respect to options to purchase Company Shares issued by the
         Company to the employees of the Company listed on Schedule 1.10
         pursuant to its stock option plans ("Options"), whether vested or
         unvested, shall be assumed by the Buyer.

                   (b) Immediately after the Effective Time, each Option
         outstanding immediately prior to the Effective Time shall be deemed to
         constitute an option to acquire, on the same terms and conditions as
         were applicable under such Option at the Effective Time, such number of
         shares of Buyer Common Stock as is equal to the number of Company
         Shares subject to the unexercised portion of such Option multiplied by
         the Conversion Ratio (with any fraction resulting from such
         multiplication to be rounded up or down to the nearest whole number or,
         in the case of .5, to the nearest odd number). The exercise price per
         share of each such Option shall be equal to the exercise price of such
         Option immediately prior to the Effective Time, divided by the
         Conversion Ratio. The term, exercisability, vesting schedule, status as
         an "incentive stock option" under Section 422 of the Code, if
         applicable, and all of the other terms of the Options shall otherwise
         remain unchanged. In addition to the foregoing, the applicable
         provisions of each award agreement for Options to be outstanding after
         the Effective Time will be equitably adjusted after the Spin-off
         Transaction and prior to the Closing by the Company's Board of
         Directors to reflect the Spin-off Transaction (as defined herein).


                                       -6-
<PAGE>   36
                   (c) As soon as practicable after the Effective Time, the
         Buyer or the Surviving Corporation shall deliver to the holders of
         Options appropriate notices setting forth such holders' rights pursuant
         to such Options, as amended by this Section 1.10, and the agreements
         evidencing such Options shall continue in effect on the same terms and
         conditions (subject to the amendments provided for in this Section 1.10
         and such notice).

                   (d) The Buyer shall take all corporate action necessary to
         reserve for issuance a sufficient number of shares of Buyer Common
         Stock for delivery upon exercise of the Options. As soon as practicable
         after the Effective Time, the Buyer shall file a Registration Statement
         on Form S-8 (or any successor form) under the Securities Act of 1933,
         as amended (the "Securities Act") with respect to all shares of Buyer
         Common Stock subject to such Options that may be registered on a Form
         S-8, and shall use its best efforts to maintain the effectiveness of
         such Registration Statement for so long as such Options remain
         outstanding.

                   (e) The Company shall obtain, prior to the Closing, the
         consent from each holder of an Option to the adjustment or amendment,
         as the case may be, of such Option or Right pursuant to this Section 
         1.10 (unless such consent is not required under the terms of the
         applicable agreement, instrument or plan).

              1.11 Certificate of Incorporation. The Certificate of
         Incorporation of the Surviving Corporation shall be the same as the
         Certificate of Incorporation of the Transitory Subsidiary immediately
         prior to the Effective Time, except that the name of the corporation
         set forth therein shall be changed to the name of the Company.

              1.12 By-laws. The By-laws of the Surviving Corporation shall be
         the same as the By-laws of the Transitory Subsidiary immediately prior
         to the Effective Time, except that the name of the corporation set
         forth therein shall be changed to the name of the Company.

              1.13 Directors and Officers. The directors of the Transitory
         Subsidiary shall become the directors of the Surviving Corporation as
         of the Effective Time. The officers of the Company shall remain as
         officers of the Surviving Corporation after the Effective Time,
         retaining their respective positions, except as specified by the Buyer
         pursuant to Section 5.2(g).

              1.14 No Further Rights. From and after the Effective Time, no
         Company Shares shall be deemed to be outstanding, and holders of
         Certificates shall cease to have any rights with respect thereto,
         except as provided in this Agreement or by law.

<PAGE>   37
              1.15 Closing of Transfer Books. At the Effective Time, the stock
         transfer books of the Company shall be closed and no transfer of
         Company Shares shall thereafter be made. If, after the Effective Time,
         Certificates are presented to the Surviving Corporation or the Exchange
         Agent, they shall be cancelled and exchanged for Merger Shares in
         accordance with Section 1.5(a), subject to applicable law in the case
         of Dissenting Shares.

              1.16 Tax-Free Reorganization. The Parties intend to adopt this
         Agreement as a tax-free plan of reorganization and to consummate the
         Merger in accordance with the provisions of Section 368(a)(1)(B) of the
         Code. The Buyer represents and covenants that:

                   (a) The Surviving Corporation will pay its dissenting
         stockholders the value of their Dissenting Shares out of its own funds.
         No funds will be supplied for that purpose, directly or indirectly, by
         the Buyer, nor will the Buyer directly or indirectly reimburse the
         Surviving Corporation for any payments for Dissenting Shares.

                   (b) The Buyer presently intends, and at the Effective Time it
         will intend, to continue the Company's historic business or use a
         significant portion of the Company's historic business assets in a
         business.

                   (c) The Buyer has no plan or intention to liquidate the
         Surviving Corporation; to merge the Surviving Corporation into another
         corporation; to cause the Surviving Corporation to sell or otherwise
         dispose of any of its assets, except for dispositions made in the
         ordinary course of the Surviving Corporation's business; or to sell or
         otherwise dispose of any of the Company Shares acquired in the Merger,
         except for transfers described in Section 368(a)(2)(C) of the Code.

                   (d) The Buyer has no plan or intention to reacquire any Buyer
         Common Stock issued in the Merger.

                   (e) Neither the Buyer nor the Transitory Subsidiary is an
         investment company as defined in Section 368(a)(2)(F)(iii) and (iv)) of
         the Code.

                   (f) The payment of cash in lieu of fractional shares of Buyer
         Common Stock is solely for the purpose of avoiding the expense and
         inconvenience to the Buyer of issuing fractional shares and shall not
         represent separately bargained-for consideration. The total cash
         consideration that will be paid in the transaction to the Company
         Stockholders instead of issuing fractional shares of Buyer Common Stock
         will not exceed one


                                       -8-
<PAGE>   38
         percent of the total consideration that will be issued in the Merger to
         the Company Stockholders in exchange for their Company Shares. The
         fractional share interests of each Company Stockholder will be
         aggregated, and no Company Stockholder will receive cash in an amount
         equal to or greater than the value of one full share of Buyer Common
         Stock.

                   (g)  The Transitory Subsidiary is solely and directly
         owned by the Buyer.

                   (h) Neither the Buyer nor an affiliate of the Buyer has
         acquired Company Shares since June 1, 1991. The Buyer and its
         affiliates own no Company Shares. During the period from the date of
         this Agreement to the Effective Time, other than pursuant to this
         Agreement, neither the Buyer nor any affiliate of the Buyer shall
         acquire any Company Shares.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

              The Company represents and warrants to the Buyer that the
         statements contained in this Article II are true and correct, except as
         set forth in the disclosure schedule attached hereto (the "Disclosure
         Schedule"). The Disclosure Schedule shall be initialed by the Parties
         and shall be arranged in paragraphs corresponding to the numbered and
         lettered paragraphs contained in this Article II, and the disclosures
         in any paragraph of the Disclosure Schedule shall qualify only the
         corresponding paragraph in this Article II.

              2.1 Organization, Qualification and Corporate Power. The Company
         is a corporation duly organized, validly existing and in corporate and
         tax good standing under the laws of the state of its incorporation. The
         Company is duly qualified to conduct business and is in corporate and
         tax good standing under the laws of each jurisdiction in which the
         nature of the business described on Section 2.1 of the Disclosure
         Schedule (the "Modem Business") or the ownership or leasing of its
         properties relating to the Modem Business requires such qualification
         except where the failure to be so qualified would not have a material
         adverse effect on the Company and its Modem Subsidiaries (as defined
         below) taken as a whole. The Company has all requisite corporate power
         and authority to carry on the Modem Business in which it is engaged and
         to own and use the properties owned and used by it in the Modem
         Business. The Company has furnished to the Buyer true and complete

         thereof will be, duly authorized, validly issued, fully paid,

         Securities Act, of any Company Shares other than as set forth in
         Section 2.2 of the Disclosure Schedule. All of the issued and
         outstanding Company Shares were issued in compliance with applicable
         federal and state securities laws.

              2.3 Authorization of Transaction. The Company has all requisite

         approval of the Merger by a majority of the votes represented by the
         outstanding Company Shares entitled to vote on this Agreement and the

         Company of this Agreement and the consummation by the Company of the
         transactions contemplated by this Agreement have been duly and validly
         authorized by all necessary corporate action on the part of the
         Company. This Agreement has been duly and validly executed and

         is bound or to which any of their assets is subject, other than any
         conflict, breach, default, acceleration, termination, modification or
         cancellation which individually or in the aggregate would not have a
         material adverse effect on the assets, business, financial condition,
         results of operations or future prospects of the Company and its
         Subsidiaries, taken as a whole, or on the ability of the Parties to

         ("Ordinary Course of Business") of the Company and not material to the
         Company.

              2.5 Subsidiaries. Section 2.5 of the Disclosure Schedule lists
         each Subsidiary and each Modem Subsidiary and sets forth for each Modem
         Subsidiary (a) its jurisdiction of incorporation, (b) the number of
         shares of authorized capital stock of each class of its capital stock,
         (c) the number of issued and outstanding shares of each class of its
         capital stock, the names of the holders thereof and the number of
         shares held by each such holder, (d) the number of shares of its
         capital stock held in treasury, and (e) its directors and officers.
         Each Modem Subsidiary is a corporation duly organized, validly existing
         and in good standing under the laws of the jurisdiction of its
         incorporation. Each Modem Subsidiary is duly qualified to conduct
         business and is in corporate and tax good standing under the laws of
         each jurisdiction in which the nature of its businesses or the
         ownership or leasing of its properties requires such qualification
         except where the failure to be so qualified would not have a material
         adverse effect on the Company and the Modem Subsidiaries taken as a
         whole. Each Modem Subsidiary has all requisite corporate power and
         authority to carry on the Modem Business in which it is engaged and to
         own and use the properties owned and used by it in the Modem Business.
         The Company has delivered or made available to the Buyer correct and
         complete copies of the charter and By-laws of each Modem Subsidiary, as
         amended to date. No Modem Subsidiary is in violation of any provision
         of its charter or By-laws. All of the issued and outstanding shares of
         capital stock of each Modem Subsidiary are duly authorized, validly
         issued, fully paid, nonassessable and free of preemptive rights. All
         shares of each Modem Subsidiary that are held of record or owned
         beneficially by either the Company or any Modem Subsidiary are held or
         owned free and clear of any restrictions on transfer (other than
         restrictions under the Securities Act and state securities laws or as
         set forth in Section 2.5 of the Disclosure Schedule), claims, Security
         Interests, options, warrants, rights, contracts, calls, commitments,
         equities and demands. There are no outstanding or authorized options,


                                      -12-
<PAGE>   42
         warrants, rights, agreements or commitments to which the Company or any
         Modem Subsidiary is a party or which are binding on any of them
         providing for the issuance, disposition or acquisition of any capital
         stock of any Modem Subsidiary. There are no outstanding stock
         appreciation, phantom stock or similar rights with respect to any Modem
         Subsidiary. There are no voting trusts, proxies, or other agreements or
         understandings with respect to the voting of any capital stock of any
         Modem Subsidiary, except as set forth in Section 2.5 of the Disclosure
         Schedule. The Company does not control directly or indirectly or have
         any direct or indirect equity participation in any corporation,
         partnership, trust, or other business association which is not a
         Subsidiary.

              2.6 Reports and Financial Statements. The Company has previously
         furnished or made available to the Buyer complete and accurate copies,
         as amended or supplemented, of its (a) Annual Report on Form 10-K for
         the fiscal years ended July 31, 1994, and July 31, 1995, as filed with
         the Securities and Exchange Commission (the "SEC"), (b) proxy
         statements relating to all meetings of its stockholders (whether annual
         or special) since July 31, 1994, and (c) all other reports or
         registration statements, other than Registration Statements on Form
         S-8, filed by the Company with the SEC since July 31, 1994 (such annual
         reports, proxy statements, registration statements and other filings,
         together with any amendments or supplements thereto, are collectively
         referred to in this Agreement as the "Company Reports"). The Company
         Reports constitute all of the documents filed or required to be filed
         by the Company with the SEC since July 31, 1994, other than any
         Registration Statement on Form S-8. As of their respective dates, the
         Company Reports filed since July 31, 1994, did not contain any untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, in
         light of the circumstances under which they were made, not misleading.
         The audited financial statements and unaudited interim financial
         statements of the Company included in the Company Reports filed since
         July 31, 1994 (together, the "Financial Statements"), (i) comply as to
         form in all material respects with applicable accounting requirements
         and the published rules and regulations of the SEC with respect
         thereto, (ii) have been prepared in accordance with United States
         generally accepted accounting principles ("GAAP") applied on a
         consistent basis throughout the periods covered thereby (except as may
         be indicated therein or in the notes thereto, and in the case of
         quarterly financial statements, as permitted by Form 10-Q under the
         Exchange Act), (iii) fairly present the consolidated financial
         condition, results of operations and cash flows of the Company and the
         Subsidiaries as of the respective dates thereof and for the periods
         referred to


                                      -13-
<PAGE>   43
         therein, and (iv) are consistent with the books and records of the
         Company and the Subsidiaries.

              2.7 Undisclosed Liabilities. As of the date hereof, none of the
         Company and its Subsidiaries has any material liability (whether known
         or unknown, whether absolute or contingent, whether liquidated or
         unliquidated and whether due or to become due), except for (a)
         liabilities shown on the balance sheet included in the Company's most
         recent Quarterly Report on Form 10-Q filed with the SEC on March 15,
         1996 (the "Most Recent Balance Sheet"), (b) liabilities which have
         arisen since January 31, 1996, in the Ordinary Course of Business, (c)
         contractual liabilities incurred in the Ordinary Course of Business
         which are not required by GAAP to be reflected on a balance sheet and
         (d) liabilities disclosed in Section 2.18 of the Disclosure Schedule.
         As used in this Section 2.7, "material liability" is deemed to mean a
         liability in excess of $100,000.

              2.8  Tax Matters.

                   (a) Each of the Company and the Subsidiaries has filed all
         material Tax Returns (as defined below) that it was required to file
         (taking into account extensions) and to the knowledge of the Company no
         material position is reflected in a Tax Return for which there was not
         substantial authority (as defined in Section 6662 of the Code) or
         comparable foreign, federal, state or local law. Each of the Company
         and the Subsidiaries has paid all Taxes (as defined below) that are
         shown to be due on any such Tax Returns. The unpaid Taxes of the
         Company and the Subsidiaries for tax periods through the date of the
         Most Recent Balance Sheet are appropriately accrued or reserved for on
         the Most Recent Balance Sheet. Neither the Company nor any Subsidiary
         has any actual or potential liability for any Tax obligation of any
         taxpayer (including without limitation any affiliated group of
         corporations or other entities that included the Company or any
         Subsidiary during a prior period) other than the Company and the
         Subsidiaries. All material Taxes that the Company or any Subsidiary is
         or was required by law to withhold or collect have been duly withheld
         or collected and, to the extent required, have been paid to the proper
         Governmental Entity. For purposes of this Agreement, "Taxes" means all
         taxes, charges, fees, levies or other similar assessments or
         liabilities, including without limitation income, gross receipts, ad
         valorem, premium, value-added, excise, real property, personal
         property, sales, use, transfer, withholding, employment, payroll and
         franchise taxes imposed by the United States of America or any state,
         local or foreign government, or any agency thereof, or other political
         subdivision of the United States or any such government, and any
         interest, fines, penalties, assessments or additions to tax resulting
         from,


                                      -14-
<PAGE>   44
         attributable to or incurred in connection with any tax or any contest
         or dispute thereof. For purposes of this Agreement, "Tax Returns" means
         all reports, returns, declarations, statements or other information
         required to be supplied to a taxing authority in connection with Taxes.

                   (b) The Company has delivered to the Buyer correct and
         complete copies of all federal income Tax Returns, examination reports
         and statements of deficiencies assessed against or agreed to by any of
         the Company or any Subsidiary between January 1, 1989 and the date
         hereof. The federal income Tax Returns of the Company have been audited
         by the Internal Revenue Service (the "IRS") or are closed by the
         applicable statute of limitations for all taxable years through July
         31, 1986. As of the date hereof, no federal or state income tax
         examination or audit of any Tax Returns of the Company or any
         Subsidiary by any Governmental Entity is currently in progress or, to
         the knowledge of the Company and the Subsidiaries, threatened or
         contemplated. As of the date hereof, neither the Company nor any
         Subsidiary has waived any statute of limitations with respect to taxes
         or agreed to an extension of time with respect to a tax assessment or
         deficiency.

                   (c) Neither the Company nor any Subsidiary is a "consenting
         corporation" within the meaning of Section 341(f) of the Code and none
         of the assets of the Company or the Subsidiaries are subject to an
         election under Section 341(f) of the Code. Neither the Company nor any
         Subsidiary has been a United States real property holding corporation
         within the meaning of Section 897(c)(2) of the Code during the
         applicable period specified in Section 897(c)(l)(A)(ii) of the Code.
         Neither the Company nor any Subsidiary is a party to any Tax allocation
         or sharing agreement.

                   (d) Neither the Company nor any Subsidiary is or has ever
         been a member of an "affiliated group" of corporations (within the
         meaning of Section 1504 of the Code), other than a group of which only
         the Company and the Subsidiaries are members. Neither the Company nor
         any Subsidiary has made an election under Treasury Reg. Section 
         1.1502-20(g). Neither the Company nor any Subsidiary is or has been
         required to make a basis reduction pursuant to Treasury Reg. Section 
         1.1502-20(b) or Treasury Reg. Section 1.337(d)-2T(b).

              2.9 Assets. Each of the Company and the Subsidiaries owns or
         leases all tangible assets necessary for the conduct of the Modem
         Business as presently conducted and as presently proposed by the
         Company to be conducted. Each such tangible asset is free from material
         defects, has been maintained in accordance with normal industry
         practice, is in good operating condition and


                                      -15-

         purposes for which it presently is used. Except as set forth in
         Section 2.9 of the Disclosure Schedule, no material asset of the
         Company (tangible or intangible) is subject to any Security Interest.

              2.10  Owned Real Property.  Neither the Company nor any Modem
         Subsidiary owns any real property.

              2.11  Intellectual Property.

                   (a) Each of the Company and the Subsidiaries owns, or is
         licensed or otherwise possesses legally enforceable rights under all
         patents and patent applications listed in Section 2.11 of the
         Disclosure Schedule and the right to use all trademarks, trade names,
         service marks, copyrights, and any applications for such trademarks,

         of the Disclosure Schedule that are used to conduct its Modem Business
         as currently conducted or as currently planned by the Company to be
         conducted (collectively, "Intellectual Property") and, except as
         qualified by or disclosed in Section 2.11 of the Disclosure Schedule,
         is aware of no intellectual property right of any third party that may
         prevent the Company or its Subsidiaries from conducting its Modem
         Business as currently conducted or as planned by the Company to be
         conducted. Section 2.11 of the Disclosure Schedule lists (i) all
         patents and patent applications and all trademarks, registered
         copyrights, trade names and service marks which are both owned by and
         used in the Modem Business, including the jurisdictions in which each
         such Intellectual Property right has been issued or registered or in
         which any such application for such issuance or registration has been
         filed, (ii) all material written licenses, sublicenses and other

         agreements as to which the Company or a Subsidiary is a party and

         which are used in the Modem Business or which form a part of any
         product or service relating to the Modem Business ("Third Party
         Intellectual Property Rights"). Neither the Company nor any Subsidiary
         is a party to any oral license, sublicense or agreement which, if
         reduced to written form, would be required to be listed in Section 2.11
         of the Disclosure Schedule under the terms of this Section 2.11.

<PAGE>   46
                   (b) Neither the Company nor any of the Subsidiaries is, nor
         will any of them be as a result of the execution and delivery of this
         Agreement or the performance of the Company's obligations under this
         Agreement, knowingly infringing upon any intellectual property rights
         of others or in breach of any license, sublicense or other agreement
         relating to the Intellectual Property or Third Party Intellectual
         Property Rights, except as qualified by or disclosed in Section 2.11 of
         the Disclosure Schedule.

                   (c) Except as set forth in Section 2.11 of the Disclosure
         Schedule, neither the Company nor any of the Subsidiaries has been
         named in any suit, action or proceeding which involves a claim of
         infringement of any Intellectual Property right of any third party.
         Except as qualified by or disclosed in Section 2.11 of the Disclosure
         Schedule, the manufacturing, marketing, licensing or sale of the
         products or performance of the service offerings of the Company and the

         Intellectual Property right of any third party; and to the knowledge of
         the Company and the Subsidiaries, the Intellectual Property rights of

         or any Subsidiary is a party or, to the knowledge of the Company and
         the Subsidiaries, is threatened to be made a party.

             2.19 Product Warranty. No product manufactured, sold, leased,
         licensed or delivered by the Company or any Subsidiary relating to the

         other indemnity beyond in any material respect the applicable standard
         terms and conditions of

         sale or lease, which are set forth in Section 2.19 of the
         Disclosure Schedule.

             2.20 Employees. Part I of Section 2.20 of the Disclosure Schedule
         contains a list of all employees of the Company and each Subsidiary who
         are employed in connection with the Modem Business, along with the
         position. The Company has delivered to the Buyer a list setting forth
         the annual compensation of each such person. Each employee of the
         Company and each Subsidiary listed in Part II of Section 2.20 of the
         Disclosure Schedule has entered into an agreement relating to the
         confidentiality and/or assignment of inventions with the Company or a
         Subsidiary set forth opposite the employee's name, a copy of which has
         previously been delivered to the Buyer. Neither the Company nor any
         Subsidiary is a party to or bound by any collective bargaining
         agreement, nor has any of them experienced any strikes, grievances,
         claims of unfair labor practices or other collective bargaining
         disputes within the last two years. The Company and the Subsidiaries
         have no knowledge of any organizational effort made or threatened,
         either currently or within the past two years, by or on behalf of any
         labor union with respect to employees of the Company or any Subsidiary
         who are employed in connection with the Modem Business.

             2.21  Employee Benefits.

                   (a) Section 2.21(a) of the Disclosure Schedule contains a
         complete and accurate list of all Employee Benefit Plans (as defined
         below). For purposes of this Agreement, "Employee Benefit Plan" means
         any "employee pension benefit plan" (as defined in Section 3(2) of the
         Employee Retirement Income Security Act of 1974, as amended ("ERISA")),
         any "employee welfare benefit plan" (as defined in Section 3(1) of
         ERISA), and any other written or oral plan, agreement or arrangement
         involving direct or indirect severance benefits, disability benefits,
         deferred compensation, bonuses, stock options, stock purchase, phantom
         stock, stock appreciation or other forms of incentive compensation or
         post-retirement compensation maintained or contributed by the Company,
         any Subsidiary or any ERISA Affiliate (as defined below). For purposes
         of this Agreement, "ERISA Affiliate" means any entity which is a member
         of (i) a controlled group of corporations (as defined in Section 414(b)
         of the Code), (ii) a group of trades or businesses under common control
         (as defined in Section 414(c) of the Code), or (iii) an affiliated
         service group (as defined under Section 414(m) of the Code or the
         regulations under Section 414(o) of the Code), any of which includes
         the Company or a Subsidiary. Complete and accurate copies of (i) all
         Employee Benefit Plans which have been reduced to writing, (ii) written
         summaries of all unwritten Employee Benefit Plans, (iii) all related
         trust agreements, insurance contracts and summary plan descriptions,
         and


                                      -20-
<PAGE>   50
         (iv) all annual reports filed on IRS Form 5500, 5500C or 5500R for the
         last three plan years for each Employee Benefit Plan, have been
         delivered or made available to the Buyer. Each Employee Benefit Plan
         has been administered in all material respects in accordance with its
         terms and each of the Company, the Subsidiaries and the ERISA
         Affiliates has in all material respects met its obligations with
         respect to such Employee Benefit Plan and has made all required
         contributions thereto. The Company has made no commitments to make any
         voluntary contributions to or to voluntarily fund any Employee Benefit
         Plans with the exception of 401(k) matching contribution commitments
         previously communicated to employees. The Company and all Employee
         Benefit Plans are in compliance in all material respects with the
         currently applicable provisions of ERISA and the Code and the
         regulations thereunder.

                   (b) There are no investigations by any Governmental Entity,
         termination proceedings or other claims (except claims for benefits
         payable in the normal operation of the Employee Benefit Plans and
         proceedings with respect to qualified domestic relations orders), suits
         or proceedings against or involving any Employee Benefit Plan or
         asserting any rights or claims to benefits under any Employee Benefit
         Plan that could give rise to any material liability.

                   (c) All the Employee Benefit Plans that are intended to be
         qualified under Section 401(a) of the Code have received determination
         letters from the Internal Revenue Service to the effect that such
         Employee Benefit Plans are qualified and the plans and the trusts
         related thereto are exempt from federal income taxes under Sections 
         401(a) and 501(a), respectively, of the Code, no such determination
         letter has been revoked and, to the knowledge of the Company, such
         revocation has not been threatened, and no such Employee Benefit Plan
         has been amended since the date of its most recent determination letter
         or application therefor in any respect, and, to the knowledge of the
         Company, no act or omission has occurred, that would adversely affect
         its qualification or materially increase its cost.

                   (d) Neither the Company, any Subsidiary, nor any ERISA
         Affiliate has, during the six years preceding the Effective Time,
         maintained an Employee Benefit Plan subject to Section 412 of the Code
         or Title IV of ERISA.

                   (e) At no time has the Company, any Subsidiary or any ERISA
         Affiliate been obligated to contribute to any "multi-employer plan" (as
         defined in Section 4001(a)(3) of ERISA).

                   (f)  There are no unfunded obligations under any
         Employee Benefit Plan providing benefits after termination of


                                      -21-
<PAGE>   51
         employment to any employee of the Company or any Subsidiary (or to any
         beneficiary of any such employee), including but not limited to retiree
         health coverage and deferred compensation, but excluding continuation
         of health coverage required to be continued under Section 4980B of the
         Code or state insurance law.

                   (g) To the knowledge of the Company, no act or omission has
         occurred and no condition exists with respect to any Employee Benefit
         Plan maintained by the Company, any Subsidiary or any ERISA Affiliate
         that would subject the Company, any Subsidiary or any ERISA Affiliate
         to any material fine, penalty, tax or liability of any kind imposed
         under ERISA or the Code.

                   (h) Except as set forth on Section 2.21(h) of the Disclosure
         Schedule, no Employee Benefit Plan is funded by, associated with, or
         related to a "voluntary employee's beneficiary association" within the
         meaning of Section 501(c)(9) of the Code.

                   (i) No Employee Benefit Plan, plan documentation or
         agreement, summary plan description or other written communication
         distributed generally to employees by its terms prohibits the Company
         or, if applicable, the Subsidiary or ERISA Affiliate, from amending or
         terminating any such Employee Benefit Plan.

                   (j) Section 2.21(j) of the Disclosure Schedule discloses
         each: (i) agreement with any director, executive officer or other key
         employee of the Company or any Subsidiary (A) the benefits of which are
         contingent, or the terms of which are materially altered, upon the
         occurrence of a transaction involving the Company or any Subsidiary of
         the nature of any of the transactions contemplated by this Agreement,
         (B) providing any term of employment or compensation guarantee or (C)
         providing severance benefits or other benefits after the termination of
         employment of such director, executive officer or key employee; (ii)
         agreement, plan or arrangement under which any person may receive
         payments from the Company or any Subsidiary that may be subject to the
         tax imposed by Section 4999 of the Code or included in the
         determination of such person's "parachute payment" under Section 280G
         of the Code; and (iii) agreement or plan binding the Company or any
         Subsidiary, including without limitation any stock option plan, stock
         appreciation right plan, restricted stock plan, stock purchase plan,
         severance benefit plan, or any Employee Benefit Plan, any of the
         benefits of which will be increased, or the vesting of the benefits of
         which will be accelerated, by the occurrence of any of the transactions
         contemplated by this Agreement or the value of any of the benefits of
         which will be calculated on the basis of any of the transactions
         contemplated by this Agreement.

             2.22  Environmental Matters.

                   (a) Each of the Company and the Subsidiaries has complied
         with all applicable Environmental Laws (as defined below), except for
         violations of Environmental Laws that do not, individually or in the
         aggregate, have a material adverse effect on the assets, business,
         financial condition, or results of operations of the Company and the
         Subsidiaries. To the knowledge of the Company and the Subsidiaries,
         there are no pending, threatened civil or criminal litigation, written
         notice of violation, formal administrative proceeding, or
         investigation, inquiry or information request by any Governmental
         Entity, relating to any Environmental Law involving the Company or any
         Subsidiary, except for litigation, notices of violations, formal
         administrative proceedings or investigations, inquiries or information
         requests that will not, individually or in the aggregate, have a
         material adverse effect on the assets, business, financial condition or
         results of operations of the Company and the Subsidiaries. For purposes
         of this Agreement, "Environmental Law" means any federal, state or
         local law, statute, rule or regulation or the common law currently in
         existence and relating to the environment or occupational health and
         safety, including without limitation any statute, regulation or order
         pertaining to (i) treatment, storage, disposal, generation and
         transportation of toxic or hazardous substances or solid or hazardous
         waste; (ii) air, water and noise pollution; (iii) groundwater and soil
         contamination; (iv) the release or threatened release into the
         environment of industrial, toxic or hazardous substances, or solid or
         hazardous waste, including without limitation emissions, discharges,
         injections, spills, escapes or dumping of pollutants, contaminants or
         chemicals; (v) the protection of wild life, marine sanctuaries and
         wetlands; (vi) underground and other storage tanks or vessels; and
         (vii) manufacture, processing, use, distribution, treatment, storage,
         disposal, transportation or handling of pollutants, contaminants,
         chemicals or toxic or hazardous substances or oil or petroleum products
         or solid or hazardous waste. As used in this Section 2.22, the terms
         "release" and "environment" shall have the meaning set forth in the
         federal Comprehensive Environmental Compensation, Liability and
         Response Act of 1980 ("CERCLA").

                   (b) Except as disclosed in Section 2.22(b) of the Disclosure
         Schedule, to the knowledge of the Company and the Subsidiaries, there
         have been no releases of any Materials of Environmental Concern (as
         defined below) into the environment at any parcel of real property or
         any facility formerly or currently owned, operated or controlled by the
         Company or a Subsidiary. With respect to any such releases of Materials
         of Environmental Concern, the Company or such Subsidiary has given all
         required


                                      -23-
<PAGE>   53
         notices to Governmental Entities (copies of which have been provided to
         the Buyer). Neither the Company nor any Subsidiary has any knowledge of
         any releases of Materials of Environmental Concern at any adjacent,
         adjoining or contiguous parcels of real property or facilities that
         could reasonably be expected to have a material adverse effect on the
         real property or facilities owned, operated or controlled by the
         Company or a Subsidiary. For purposes of this Agreement, "Materials of
         Environmental Concern" means any chemicals, pollutants or contaminants,
         hazardous substances (as such term is defined under CERCLA), solid
         wastes and hazardous wastes (as such terms are defined under the
         federal Resources Conservation and Recovery Act), toxic materials, oil
         or petroleum and petroleum products, or any other material subject to
         regulation under any Environmental Law.

                   (c) Set forth in Section 2.22(c) of the Disclosure Schedule
         is a list of all formal, written environmental reports, investigations
         and audits relating to premises currently or previously owned or
         operated by the Company or a Subsidiary (whether conducted by or on
         behalf of the Company or a Subsidiary or a third party, and whether
         done at the initiative of the Company or a Subsidiary or directed by a
         Governmental Entity or other third party) which were issued or
         conducted during the past five years and which the Company has
         possession of. Complete and accurate copies of each such report, or the
         results of each such investigation or audit, have been provided to the
         Buyer and any reliance by the Buyer on such reports, investigations or
         audits is at the Buyer's sole risk.

             2.23 Legal Compliance. Each of the Company and the Modem
         Subsidiaries, and the conduct and operations of their respective
         businesses, are in compliance with each law (including rules and
         regulations thereunder) of any federal, state, local or foreign
         government, or any Governmental Entity, which (a) affects or relates to
         this Agreement or the transactions contemplated by this Agreement or
         (b) is applicable to the Company or such Modem Subsidiary or such
         business, except for any violation of or default under a law referred
         to in clause (b) above which reasonably may be expected not to have a
         material adverse effect on the assets, business, financial condition,
         results of operations or future prospects of the Company and the Modem
         Subsidiaries taken as a whole.

             2.24 Permits. Section 2.24 of the Disclosure Schedule sets forth a
         list of all permits, licenses, registrations, certificates, orders or
         approvals from any Governmental Entity (including without limitation
         those issued or required under Environmental Laws and those relating to
         the occupancy or use of owned or leased real property) ("Permits")
         issued to or held by


                                      -24-
<PAGE>   54
         the Company or any Subsidiary relating to the Modem Business. Such
         listed Permits are the only Permits that are required for the Company
         and the Subsidiaries to conduct the Modem Business as presently
         conducted or as proposed by the Company to be conducted, except for
         those the absence of which would not have any material adverse effect
         on the assets, business, financial condition, results of operations or
         future prospects of the Company and the Modem Subsidiaries taken as a
         whole. Each such Permit is in full force and effect and, to the best of
         the knowledge of the Company or any Subsidiary, no suspension or
         cancellation of such Permit is threatened and there is no basis for
         believing that such Permit will not be renewable upon expiration. Each
         such Permit will continue in full force and effect following the
         Closing.

             2.25 Certain Business Relationships With Affiliates. Except as set
         forth in Section 2.25 of the Disclosure Schedule, no Affiliate of the
         Company (a) owns any property or right, tangible or intangible, which
         is used in the Modem Business, (b) has any claim or cause of action
         against the Company or any Modem Subsidiary other than in the Ordinary
         Course of Business, or (c) owes any money to the Company or any Modem
         Subsidiary. Section 2.25 of the Disclosure Schedule describes any
         transactions or relationships other than in the Ordinary Course of
         Business between the Company and any Affiliate thereof which are not
         reflected in the statements of operations of the Company included in
         the Financial Statements.

             2.26 Brokers' Fees. Except for the obligations of the Company to
         Broadview Associates, L.L.C. ("Broadview") pursuant to that certain
         Letter Agreement dated March 18, 1996, neither the Company nor any
         Subsidiary has any liability or obligation to pay any fees or
         commissions to any broker, finder or agent with respect to the
         transactions contemplated by this Agreement.

             2.27 Books and Records. The minute books and other similar records
         of the Company and each Modem Subsidiary contain true and complete
         records of all actions taken at any meetings of the Company's or such
         Subsidiary's stockholders, Board of Directors or any committee thereof
         and of all written consents executed in lieu of the holding of any such
         meeting. The books and records of the Company and each Modem Subsidiary
         accurately reflect in all material respects the assets, liabilities,
         business, financial condition and results of operations of the Company
         or such Subsidiary and have been maintained in accordance with good
         business and bookkeeping practices.

                   (b) The Company has received the written opinion of
         Broadview, dated the date hereof, to the effect that the consideration

         financial point of view to the Company Stockholders. A copy of such
         opinion has been previously furnished to the Buyer.

             2.29 Disclosure. No representation or warranty by the Company
         contained in this Agreement, and no statement contained in the
         Disclosure Schedule or any other document, certificate or other
         instrument delivered to or to be delivered by or on behalf of the

         by the Company or any of its representatives in connection with this
         Agreement, contains or will contain any untrue statement of a material

         of the book value of the assets and liabilities retained by the Company
         on the Closing Date, the Company shall have a tangible net worth of not
         less than One Dollar ($1).

         to hold, in confidence all such information in accordance with the
         terms of the Confidentiality Agreement dated March 18, 1996 between the
         Buyer and the Company.

              4.8 Notice of Breaches. The Company shall promptly deliver to the
         Buyer written notice of any event or development that would (a) render
         any representation or warranty of the Company contained in Sections 
         2.1, 2.2, 2.3, 2.4, 2.5, 2.7, 2.8, 2.10, 2.16, and 2.26 (including the
         Disclosure Schedule) inaccurate or incomplete in any material respect,
         or (b) constitute or result in a breach by the Company of, or a failure
         by the Company to comply with, any agreement or covenant in this
         Agreement applicable to such party. The Buyer or the Transitory
         Subsidiary shall promptly deliver to the Company written notice of any
         event or development that would (i) render any statement,
         representation or warranty of the Buyer or the Transitory Subsidiary in
         this Agreement inaccurate or incomplete in any material respect, or
         (ii) constitute or result in a breach by the Buyer or the Transitory
         Subsidiary of, or a failure by the Buyer or the Transitory Subsidiary
         to comply with, any agreement or covenant in this Agreement applicable
         to such party. No such disclosure shall be deemed to avoid or cure any
         such misrepresentation or breach.

         its best efforts to cause its Affiliates and each of its officers,

         relating to the Modem Business, tender offer, recapitalization,

         other provision of this Agreement, neither the provisions contained in
         this Section 4.9 or elsewhere in this Agreement shall prohibit the
         Board of Directors of the Company from (i) furnishing information to or
         entering into discussions or negotiations with, any person or entity
         that makes an unsolicited bona fide written proposal to acquire the
         Company (or the Modem Business) pursuant to a merger, consolidation,
         share exchange, purchase of a substantial portion of the assets,
         business combination or other similar transaction, if the Board of
         Directors of the Company determines in good faith, based as to legal
         matters on the advice of counsel, that such action is required for the
         Board of Directors to comply with its fiduciary duties to stockholders
         imposed by law (the "Company Board Fiduciary Duties") and (ii)
         complying with Rule 14c-2 of the Exchange Act with regard to any
         Acquisition Proposal, if applicable, "Acquisition Proposal" shall mean
         any proposed (A) merger, consolidation or similar transaction involving
         the Company, (B) sale, lease or other disposition directly or
         indirectly by merger, consolidation, share exchange or otherwise of
         assets of the Company or the Subsidiaries representing 30% or more of
         the Modem Business or of the consolidated assets of the Company and the
         Subsidiaries, (C) issue, sale, or other disposition of (including by
         way of merger, consolidation, share exchange or any similar
         transaction) securities (or options, rights or warrants to purchase, or
         securities convertible into, such securities) representing 30% or more
         of the voting power of the Company or (D) transaction in which any
         person shall acquire beneficial ownership (as such term is defined in
         Rule 13d-3 under the Exchange Act), or the right to acquire beneficial
         ownership, or any "group" (as such term is defined under the Exchange
         Act) shall have been formed which beneficially owns or has the right to
         acquire beneficial ownership, of 30% or more of the outstanding Company
         Common Stock. The exercise of the Company Board Fiduciary Duties,
         notwithstanding any other provision of this Agreement, shall not
         constitute a breach or violation of any provision of this Agreement.
         The Company shall immediately notify the Buyer of, and shall disclose
         to the Buyer all details of, any inquiries, discussions or negotiations
         of the nature described in this Section 4.9.

              4.10 Agreements from Certain Affiliates of the Company.
         Concurrently with or prior to the execution of this Agreement, the
         Company shall deliver to the Buyer a list of all persons or entities
         who are at such time "affiliates" of the Company as that term is used
         in paragraphs (c) and (d) of Rule 145 under the Securities Act (the
         "Company Affiliates"). In order to help ensure that the issuance of
         Merger Shares will comply with the Securities Act and that the Merger
         will be treated as a tax-free reorganization, the Company shall use all
         reasonable efforts to cause each Company Affiliate to execute and
         deliver to the Buyer, prior to the distribution of the Prospectus/Proxy
         Statement in accordance with Section 4.4(b), a written agreement
         substantially in the form attached hereto as Exhibit B (the "Affiliate
         Agreement"). If any Company Affiliate fails to execute and deliver an
         Affiliate Agreement, the Buyer shall be entitled to place appropriate
         legends on the certificates evidencing the Merger Shares to be issued
         to such person or entity and any other shares of Buyer Common Stock
         issued to such person or entity upon exercise of an Option or Other
         Right, and to issue appropriate stock transfer instructions to the
         transfer agent for the Buyer Common Stock, to the effect that such
         shares may be sold publicly only in compliance with Rule 145 under the
         Securities Act.

              4.11 Listing of Merger Shares.  The Buyer shall list the
         Merger Shares on the NYSE.

              4.12 Indemnification; Release.

                   (a) From and after the Effective Time, the Buyer shall
         indemnify, defend and hold harmless the officers, directors and
         employees of the Company and the Subsidiaries (individually, an
         "Indemnified Party" and collectively, the "Indemnified Parties")
         against all losses, expenses, claims, damages or liabilities ("Claims")
         based on the fact that such person is or was such officer, director or
         employee of the Company or the Subsidiaries (including arising out of
         the transactions contemplated by this Agreement) to the fullest extent
         permitted or required under applicable law; provided, however, that no
         Indemnified Party shall be entitled to indemnification pursuant to this
         Section 4.12 for Claims based on the fact that such person is or was a
         stockholder of the Company. The Buyer agrees that all rights to
         indemnification existing in favor of the directors, officers or
         employees of the Company as provided in the Company's or the
         Subsidiaries' respective Articles or Certificate of Incorporation or
         By-Laws or Code of Regulations, as in effect as of the date hereof,
         with respect to matters occurring through the Effective Time, shall
         survive the Merger and shall continue in full force and effect for a
         period of not less than six years from the Effective Time and the Buyer
         hereby guaranties unconditionally the


                                      -37-
<PAGE>   67
         satisfaction of all such rights to indemnification (and shall pay
         expenses in advance of the final disposition of any such action or
         proceeding to each Indemnified Party to the fullest extent permitted
         under Delaware law, upon receipt from the Indemnified Party to whom
         expenses are advanced of the undertaking to repay such advances
         contemplated by Section 145(e) of the Delaware General corporation
         Law). Without limiting the foregoing, in the event any Claim is brought
         against any Indemnified Party (whether arising before or after the
         Effective Time) after the Effective Time (i) the Indemnified Parties
         may retain the Company's regularly engaged independent legal counsel or
         other independent legal counsel satisfactory to them, provided that
         such other counsel shall be reasonably acceptable to the Buyer, (ii)
         the Buyer shall pay all reasonable fees and expenses of such counsel
         for the Indemnified Parties promptly as statements therefor are
         received and (iii) the Buyer shall use its reasonable efforts to assist
         in the defense of any such matter, provided that the Buyer shall not be
         liable for any settlement of any Claim effected without its written
         consent, which consent shall not be unreasonably withheld. Any
         Indemnified Party wishing to claim indemnification under this Section 
         4.12, upon learning of any such Claim shall notify the Buyer (although
         the failure to so notify the Buyer shall not relieve the Buyer from any
         liability which the Buyer may have under this Section 4.12, except to
         the extent such failure materially prejudices the Buyer) and shall
         deliver to the Buyer the undertaking contemplated by Section 145(e) of
         the Delaware General Corporation Law. The Indemnified Parties as a
         group may retain no more than one law firm (in addition to local
         counsel) to represent them with respect to each such matter unless
         there is, under applicable standards of professional conduct (as
         determined by counsel to the Indemnified Parties), a conflict on any
         significant issue between the positions of any two or more Indemnified
         Parties, in which event such additional counsel as may be required may
         be retained by the Indemnified Parties and will be paid by the Buyer.

                   (b) The Buyer hereby remises and releases the directors,
         officers and employees of the Company from any and all claims it may
         have against them, other than claims based solely on fraud.

                   (c) The Company hereby remises and releases the directors,
         officers and employees of the Buyer from any and all claims it may have
         against them, other than claims based solely on fraud.

              4.13 Employee Matters.

                   (a)  With respect to benefit plans available to
         employees of the Company or the Modem Subsidiaries generally, for


                                      -38-

         at least one year from and after the Effective Time, the Buyer shall
         cause the Surviving Corporation to either (i) maintain all employee
         benefits of the Company or the Modem Subsidiary, as the case may be,
         including, without limitation, benefits under employee benefit plans,
         policies and arrangements, existing on the Effective Time or (ii)
         provide benefits to employees of the Surviving Corporation that are,
         taken as a whole, substantially equivalent to or better than the
         benefits offered to such persons by the Company or applicable Modem
         Subsidiary, as the case may be, immediately prior to the Effective
         Time.

                   (b) The Parties acknowledge and agree that the Surviving
         Corporation and the Modem Subsidiaries shall have the benefit of any
         confidentiality and/or nondisclosure agreement executed by employees of
         the Company or the Modem Subsidiaries. The Parties shall cause any
         employee of the Surviving Corporation who was an employee of the
         Company immediately prior to the Spin- off to agree to hold in
         confidence and to not use contrary to the interests of the Spin-off
         Company any confidential information concerning the Spin-off Company
         that is in such individual's possession at the Effective Time as a
         result of such individual's employment by the Company. The Surviving
         Corporation agrees to release any employee of the Spin-off Company who
         was an employee of the Surviving Corporation immediately prior to the
         Spin-off from any agreement not to compete with the Surviving
         Corporation or from any agreement that would prohibit such employee
         from being employed by the Spin-off Company.

              4.14 Corporate Name. From and after the Closing Date, the Buyer
         shall not, and shall cause the Surviving Corporation and all other
         Affiliates of the Buyer to not, use the name "Penril" other than in the
         Modem Business.

              4.15 Non-Interference.

                   (a) The Company agrees to cause the Spin-off Company to agree
         that between the date hereof and the Closing, and for eighteen (18)
         months after the Closing, it will not and will cause its Affiliates to
         not, induce any person who is, on the date hereof, or who becomes after
         the date hereof, an employee, officer or agent of the Buyer or any
         Affiliate of the Buyer (i) to terminate such relationship or (ii) to
         employ, or assist in employing, directly or indirectly, any such
         person.

                   (b) The Buyer agrees that between the date hereof and the
         Closing, with respect to the Company and its respective Affiliates, and
         for eighteen (18) months after the Closing with


                                      -39-

         respect to the Spin-off Company, the Buyer will not and will cause its
         Affiliates to not, induce any person who is, on the date hereof, or who
         becomes after the date hereof, an employee, officer or agent of the
         Company or the Spin-off Company and their respective Affiliates (i) to
         terminate such relationship or (ii) to employ or assist in employing,
         directly or indirectly, any such person.

              4.16 Vote of Company Shares. The Buyer covenants and agrees to
         vote, and to cause its Affiliates to vote, all Company Shares held or
         controlled by them in favor of approval of this Agreement and the
         Merger, and the transactions contemplated hereby at the Special
         Meeting.

              4.17 Non-Solicitation. The Buyer hereby covenants and agrees to
         request that its direct sales force not solicit any business from any
         of the resellers listed on Schedule 4.17 for a period of 18 months
         after the Closing, which business relates to the business to be
         transferred by the Company to the Spin-off Company in the Spin-off

         Stockholders of this Agreement or the Merger or shall have approved or
         recommended to the Company Stockholders that they accept the terms of

         foregoing actions; provided, however, that reasonable delay required to
         comply with the Company Board Fiduciary Duties shall not be deemed to

              6.2 Effect of Termination. If any Party terminates this Agreement
         pursuant to Section 6.1, all obligations of the Parties hereunder shall

         and except as provided in the last sentence of Section 4.7), provided,
         however, (i) that if the Merger is not consummated as a result of a

         5.1(e)), then, without further action on the part of any party or
         person, the license agreement in the form of Exhibit D hereto shall
         become effective upon the payment by the Buyer within 10 business days

         Section 6.1(d) of Fifty Million Dollars ($50,000,000.00) to the Company
         in immediately available funds. Notwithstanding the foregoing, if

         Agreement pursuant to Section 6.1(d) (but solely as it relates to
         Sections 5.2(a) or 5.2(c)), the Company has received, participated in
         or encouraged inquiries, discussions or negotiations of the nature
         described in Section 4.9 and the Board of Directors of the Company
         shall have approved or recommended to the Company Stockholders that
         they accept the terms of any Acquisition Proposal or shall have
         resolved to take any of the foregoing actions, with a party with whom
         they had discussions during such period, then, without further action
         or consideration on the part of any party or person, the license
         agreement in the form of Exhibit D hereto shall become effective. For
         purposes of this Section 6.2, "Special Breach" shall mean (i) any

              8.8  Governing Law.  This Agreement shall be governed by and

             8.10 Severability. Any term or provision of this Agreement that is
         invalid or unenforceable in any situation in any jurisdiction shall not
         affect the validity or enforceability of the remaining terms and
         provisions hereof or the validity or enforceability of the offending
         term or provision in any other situation or in any other jurisdiction.
         If the final judgment of a court of competent jurisdiction declares
         that any term or provision hereof is invalid or unenforceable, the
         Parties agree that the court making the determination of invalidity or
         unenforceability shall have the power to reduce the scope, duration, or
         area of the term or provision, to delete specific words or phrases, or
         to replace any invalid or unenforceable term or provision with a term
         or provision that is valid and enforceable and that comes closest to
         expressing the intention of the invalid or unenforceable term or
         provision, and this Agreement shall be enforceable as so modified after
         the expiration of the time within which the judgment may be appealed.

             8.11 Expenses. The Buyer and the Company shall each bear its own
         costs and expenses (including legal fees and expenses) incurred in
         connection with this Agreement and the transactions contemplated by
         this Agreement. The fees and expenses of the Company shall be accrued
         prior to the Closing Date and reflected on the Closing Balance Sheet.
         The fees and expenses of the Transitory Subsidiary shall be borne by
         the Buyer.

             8.12 Specific Performance. Each of the Parties acknowledges and
         agrees that one or more of the other Parties would be damaged
         irreparably in the event any of the provisions of this Agreement are
         not performed in accordance with their specific terms or otherwise are
         breached. Accordingly, each of the Parties agrees that the other
         Parties shall be entitled to an injunction or injunctions to prevent
         breaches of the provisions of this Agreement and to enforce
         specifically this Agreement and the terms and provisions hereof in any
         action instituted in any court of the United States or any state
         thereof having jurisdiction over the Parties and the matter (subject to
         the provisions of Section 8.13), in addition to any other remedy to
         which it may be entitled, at law or in equity.

             8.13 Submission to Jurisdiction. Each of the Parties (a) submits to
         the jurisdiction of any state or federal court sitting in Delaware in
         any action or proceeding arising out of or relating to this Agreement,
         (b) agrees that all claims in respect of the action or proceeding may
         be heard and determined in any such court, and (c) agrees not to bring
         any action or proceeding arising out of or relating to this Agreement
         in any other court. Each of the Parties waives any defense of
         inconvenient forum to the maintenance of any action or proceeding so
         brought and waives


                                      -48-
<PAGE>   78
         any bond, surety or other security that might be required of any other
         Party with respect thereto. Any Party may make service on another Party
         by sending or delivering a copy of the process to the Party to be
         served at the address and in the manner provided for the giving of
         notices in Section 8.7. Nothing in this Section 8.13, however, shall
         affect the right of any Party to serve legal process in any other
         manner permitted by law.

             8.14 Construction. The language used in this Agreement shall be
         deemed to be the language chosen by the Parties hereto to express their
         mutual intent, and no rule of strict construction shall be applied
         against any Party. Any reference to any federal, state, local, or
         foreign statute or law shall be deemed also to refer to all rules and
         regulations promulgated thereunder, unless the context requires
         otherwise.

             8.15 Incorporation of Exhibits and Schedules. The Exhibits and
         Schedules identified in this Agreement are incorporated in this
         Agreement by reference and made a part hereof.

             8.16 Non-Survival of Representations, Warranties and Agreements. No
         representations, warranties or agreements in this Agreement shall
         survive the Closing, except for those contained in Article I and
         Sections 4.10 (the last sentence only), 4.12, 4.13, 4.14, 4.15 and 4.17
         and, to the extent relating to such specified provisions, those
         contained in this Article VIII.

                   (a) Newsub will indemnify and save harmless Penril and its
              directors, officers, employees, agents and/or affiliates (each, a
              "Newsub Indemnified Party") from any and all costs, expenses,
              losses, damages and liabilities ("Claim(s)") incurred or suffered,
              directly or indirectly, (including, without limitation, reasonable
              legal fees and expenses) resulting from or attributable to (i) the
              operation of Newsub from and after the Distribution; (ii) any
              claim, suit or other type of proceeding based upon, arising out of
              or in connection with the operation of Penril prior to the Merger
              other than those based upon, arising out of or in connection with
              the Modem Business (as defined in the Merger Agreement), the
              Merger, the Merger Agreement, the solicitation of proxies relating
              to approval of the Merger and other transactions related to the
              Merger, the tax consequences of the Distribution; (iii) any claim,
              suit or other type of proceeding relating to the termination of
              employment of any employees of Penril other than those set forth
              on Schedule 2.20 to the Merger Agreement; and (iv) any claim, suit
              or other type of proceeding based upon, arising out of or in
              connection with any information concerning Newsub in the
              Registration Statement (as defined in the Merger Agreement) that
              was furnished by Penril and/or Newsub for inclusion in the
              Registration Statement. In furtherance thereof, Newsub
              acknowledges and agrees that (ii) above includes, but is not
              limited to, all suits, actions or administrative hearings existing
              on the date hereof to which Penril is a party (or which have been
              assigned by Penril to Newsub and assumed by Newsub) other than
              those based upon, arising out of or in connection with the Modem
              Business (collectively, the "Newsub Existing Litigation", as
              listed on Exhibit A hereto). This Agreement will constitute
              notice, in accordance with Paragraph 2 hereof, of Newsub's
              election to conduct the defense (or to prosecute, as the case may
              be) of all claims in connection with the Newsub Existing
              Litigation. Other than certain rights retained pursuant to
              Paragraph 2 hereof Penril acknowledges and agrees that Newsub will
              have all rights to, and title and interest in any such claim, suit
              or proceeding for which Newsub is providing indemnification.

                   (b) Penril will indemnify and save harmless Newsub and its
              directors, officers, employees, agents and/or affiliates (each, a
              "Penril Indemnified Party" and, together with each Newsub
              Indemnified Party, without distinction, an "Indemnified Party")
              from any and all Claims incurred or suffered, directly or
              indirectly, (including, without


                                       -2-

              limitation, reasonable legal fees and expenses) resulting from or
              attributable to (i) the operation of Penril from and after the
              Distribution; (ii) any claim, suit or other type of proceeding
              based upon, arising out of or in connection with the operation of
              the Modem Business prior to the Merger; and (iii) any claim, suit
              or other type of proceeding relating to the Merger, the Merger
              Agreement, the solicitation of proxies relating to approval of the
              Merger and the other transactions related to the Merger other than
              those based upon, arising out of or in connection with the
              Registration Statement on Form S-1, filed with the Securities and
              Exchange Commission to register the Newsub Stock in connection
              with the Distribution. In furtherance thereof, Penril acknowledges
              and agrees that (ii) above includes, but is not limited to, all
              suits, actions or administrative hearings existing on the date
              hereof to which Penril is a party (none of which have been
              assigned by Penril to Newsub or assumed by Newsub) which are based
              upon, arising out of or in connection with the Modem Business
              (collectively, the "Penril Retained Existing Litigation", as
              listed on Exhibit B hereto, and, together with the Newsub Existing
              Litigation, the "Existing Litigation"). This Agreement will
              constitute notice, in accordance with Paragraph 2 hereof, of
              Penril's election to conduct the defense (or to prosecute, as the
              case may be) of all claims in connection with the Penril Retained
              Existing Litigation. Other than certain rights retained pursuant
              to Paragraph 2 hereof Newsub acknowledges and agrees that Penril
              will have all rights to, and title and interest in any such claim,
              suit or proceeding for which Penril is providing indemnification.

              2.   Defense of Claim.

                   (a) In the event an Indemnified Party receives notice of any
              claim asserted or any action or administrative or other proceeding
              commenced in respect of a Claim for which indemnity may be
              properly sought under this Agreement against Newsub or Penril, as
              the case may be (the "Indemnifying Party"), the Indemnified Party
              shall give notice in writing to the Indemnifying Party within
              thirty (30) days of its receipt of such notice. Within thirty (30)
              days after the earlier of (a) receipt by the Indemnifying Party of
              such notice from the Indemnified Party, or (b) receipt of actual
              notice by the Indemnifying Party from sources other than the
              Indemnified Party, the Indemnifying Party may give the Indemnified
              Party written notice of its election to conduct the defense of
              such claim, action or


                                       -3-
<PAGE>   83
              proceeding at its own expense. If the Indemnifying Party has given
              the Indemnified Party such notice of election to conduct the
              defense, the Indemnifying Party may conduct the defense at its
              expense, but the Indemnified Party shall nevertheless have the
              right to participate in the defense, provided such participation
              is solely at the expense of the Indemnified Party, without a right
              of further reimbursement. If the Indemnifying Party has not so
              notified the Indemnified Party in writing within the time period
              provided above of its election to conduct the defense of such
              Claim, the Indemnified Party may, but need not, conduct, at the
              Indemnifying Party's expense, the defense of such claim, action or
              proceeding. The Indemnified Party may at any time notify the
              Indemnifying Party of its intention to settle, compromise or
              satisfy any such claim, action or proceeding (the defense of which
              the Indemnifying Party has not previously elected to conduct) and,
              with the prior written consent of the Indemnified Party (which
              consent will not be unreasonably withheld), may make such
              settlement, compromise or satisfaction, at the Indemnifying
              Party's expense, provided, however, that the Indemnifying Party
              may make such settlement, compromise or satisfaction without the
              prior written consent of the Indemnified Party if such settlement,
              compromise or satisfaction constitutes a release of the
              Indemnified Party in respect of such Claim.

                   (b) Any settlement, compromise or satisfaction, or any final
              judgment or decree entered in, any Claim or Existing Litigation
              defended in accordance with the provisions of this Paragraph 2
              shall be final and binding on the parties hereto.

                   (c) The Indemnified Party and the Indemnifying Party shall
              use all reasonable efforts to cooperate fully with respect to the
              defense of any Claim or Existing Litigation in accordance with the
              provisions of this Paragraph 2.

              3. Notice. All notices and other communications required or
         permitted to be given under this Indemnification Agreement shall be
         dated and in writing and shall be deemed to have been duly given when
         (a) personally delivered, (b) upon delivery of a telephonic facsimile
         transmission with a confirmed telephonic transmission answered back,
         (c) three days after being deposited in the United States mail,
         registered or certified, return receipt requested, postage prepaid, or
         (d) one day after having been dispatched by a nationally recognized
         overnight courier service, addressed to the party or parties to this
         Agreement to whom it is directed:

         or to such other address as may be designated by a party hereto by
         notice delivered to the other parties.

              4. Cooperation. In connection with any Claim that is the subject
         of indemnification, each party shall afford to the Indemnifying Party
         and its accountants, counsel and other designated representatives
         reasonable access during normal business hours to all records, books,
         contracts, instruments, computer data and other information insofar as
         such access is reasonably required by the indemnifying party in
         connection with the defense of any Claim pursuant to Paragraph 2
         hereof. In addition, each party shall use reasonable efforts to make
         available to the Indemnifying Party, upon written request, its
         officers, directors, employees and agents as witnesses to the extent
         that any such person may reasonably be required in connection with the
         defense or prosecution of any Claim.

             5. Waiver. The waiver by any party hereto of the breach of any
         provision of this Agreement shall not operate or be construed as a
         waiver of any preceding or succeeding breach and no failure by any
         party to exercise any right or privilege hereunder shall be deemed a
         waiver of such party's rights or privileges or shall be deemed a waiver
         of such party's rights hereunder to exercise the same at any subsequent
         time or times.

              6. Amendment. This Agreement may be amended, modified or
         supplemented only by written instrument executed by the party against
         whom enforcement is sought.

              7. Governing Law. This Agreement shall be governed by and
         construed in accordance with the internal laws of the State of
         Delaware.

              8. Severability. The invalidity, illegality or unenforceability of
         one or more of the provisions of this Agreement in any jurisdiction
         shall not affect the validity, legality or enforceability of the
         remainder of this Agreement in such jurisdiction or the validity,
         legality and enforceability of this Agreement, including any such
         provision, in any other jurisdiction, it being intended that all rights
         and obligations of the parties hereunder shall be enforceable to the
         fullest extent permitted by law.

              9. Counterparts. This Agreement may be executed in any number of
         counterparts, each of which shall be deemed to be an original, but all

                           PERPETUAL LICENSE AGREEMENT

         or directly. Although Licensee acknowledges that some cross licensors
         may be unwilling to grant such pass-through rights, Licensor agrees to

              2.3 Right to Sublicense or Assign. Licensee shall have the right
         to sublicense or assign any of the rights or licenses granted hereunder
         in connection with the manufacture and wholesale or retail sale solely
         by Licensee of the Products, provided that Licensee shall not deliver
         or make available to any other party any of the source code provided by
         Licensor hereunder.

              2.4  Software and Computer Programs in Rights, Technical
                   Information or Products.

                   (a) Licensor and Licensee agree that any and all software and
         other computer programs included in the Rights, or the Technical
         Information or the Products are being licensed by Licensor to Licensee
         in source code and machine readable object code form on a nonexclusive
         basis as set forth in Sections 2.1 (Use of Rights) and 2.2 (Use of
         Technical Information) above, and are not being sold by Licensor or

         sublicense to third parties any rights or licenses to use individual
         copies of such software in the operation of the Products.

                   (b) Licensee agrees not to copy or reproduce any of such
         software or computer programs except during the term of this Agreement
         and, provided that, Licensor's copyright and proprietary notices which
         appear on such software or computer programs are properly included on
         such copies and reproductions.

              2.5 Modifications and/or Improvements of Products. Licensee shall
         have the right to modify and improve the Products and to apply each
         such modification or improvement to the Products, without payment to or
         the consent of the Licensor. Any such modification or improvement shall
         be the property of Licensee.

              2.6 Right to Hire Designated Employees. Licensee shall have the
         right to hire within 90 days of the Effective Date as its own employees
         up to five designated Licensor employees, whose names are set forth on

         use its best efforts to assist and facilitate the hiring of such five
         employees by Licensee provided any cash expenditures by Licensor to
         such employees in connection with such efforts shall be reimbursed by
         Licensee.

              2.7 Additional Licenses. Licensee acknowledges that a license

         Licensee makes the payment described in Section 6.2 of the Merger
         Agreement, the royalty rate for each modem shall not exceed the lesser
         of $.30 per modem or the lowest rate then being charged to any other
         licensee of such patent for a comparable license, and (b) if no such
         payment is made, the royalty rate shall not exceed that then being
         charged to


                                       -4-

         any other licensee manufacturing a comparable volume of modems
         under such license.

         3.   OBLIGATIONS OF LICENSOR.

              3.1 Product Information and Literature. Licensor shall provide
         Licensee with catalogues, maintenance manuals and other descriptive

         Licensee.

              3.2 Training and Technical Assistance. To assist Licensee in

         Patents and use the Licensed Technology to its full potential. Such
         training and assistance shall be rendered by Licensor at no expense to
         Licensee; provided, however, that Licensor shall not be required to
         devote more than 20 man-hours during the term of this Agreement in
         rendering such training and technical assistance to Licensee. The
         parties hereto shall from time to time determine whether particular
         training and assistance shall be rendered at Licensor's facilities or
         at Licensee's facilities. Travel costs, lodging and all related
         expenses incurred by one party in connection with sending its employees
         or permitted sublicensees to the other party's location shall be paid
         in full by the party sending such individuals.

              3.3 Evaluations. Licensor shall provide Licensee free of charge
         with evaluations of Licensee's manufacturing, assembly, service,

         the term of this Agreement in rendering such evaluations to Licensee.
         Licensor shall use its best efforts to deliver each evaluation to
         Licensee within ten (10) days after Licensee's request of such

         servicing of the Products; provided, however, that Licensor shall not
         be required to devote more than 20 man-hours during the term of this
         Agreement in responding to such written inquiries.

              3.5 Locating Sources for Components. Licensor shall use its best
         efforts, free of charge, to identify suppliers of components, parts,
         tools and test equipment for Products, and to then assist Licensee in
         negotiating supply agreements with such suppliers; provided, however,
         that Licensor shall not be required to devote more than 20 man-hours
         during the term of this Agreement in assisting Licensee pursuant to

              3.6  Additional Services.

                   (a) Licensor shall use its reasonable efforts to provide
         Licensee with any and all additional assistance reasonably requested by
         Licensee, including without limitation: producing technical, sales,
         advertising and other reports and information for Licensee which
         Licensee believes might be useful in selling the Products manufactured
         hereunder; and assisting Licensee in attempting to obtain from third
         parties technical information, drawings, plans, specifications and
         other data which are not proprietary to Licensor and which Licensor
         does not otherwise have the right to use, in order to enable Licensee
         to respond to requests of any potential customer.

                   (b) Licensor shall bill Licensee for any such services not
         expressly provided free of charge in Section 2.2(b) (Use of Technical
         Information) or in one of the earlier provisions of this Article 3 at
         prices to be agreed in advance by the parties hereto. In all cases the
         prices charged by Licensor for the services that it provides to
         Licensee shall not exceed the prices that it charges its best customer
         or licensee, as the case may be, for the same or similar services, if
         any. Licensor shall not commence performance of any part of any
         services hereunder until such prices are established in writing by the
         parties hereto.

         4.   COMPENSATION PAYABLE TO LICENSOR.

              Licensee shall pay Licensor the amount, if any, specified in
         Section 6.2 of the Merger Agreement, such payment, if any, to be in
         immediately available funds, at the Effective Date.

         5.   INVENTIONS.

              If Licensor formulates, makes or conceives a patentable invention
         or develops any other intellectual property rights which constitutes a
         modification and/or improvement of a Product, Licensor may apply, at
         its or his own expense and discretion, for appropriate patent and other
         intellectual property right registrations of such invention or rights
         in any and all jurisdictions. In each jurisdiction where Licensor does
         not apply for such patent or registration within ninety (90) days after
         having formulated, made or conceived and reduced to practice such
         patentable invention or developed such right and after notice from
         Licensee to Licensor of Licensee's desire to have such application or
         registration made, then Licensee may either: (i) apply for such patent
         or registration in such jurisdiction, at its own expense; or (ii)
         request Licensor to apply for such patent or registration in such
         jurisdiction and then assign all of its or his rights in such
         applications to Licensee, all at Licensee's expense. Licensor shall, at
         the request of the Licensee, both during and after the term of this
         Agreement, execute such documents and render such assistance as may be
         appropriate to enable Licensee to maintain or


                                       -6-

         obtain registrations of patents or intellectual property rights in any
         jurisdiction in accordance with this Article 5.

         6.   CONFIDENTIAL INFORMATION.

              6.1 Confidentiality Maintained. Each party agrees that the other
         party hereto has a proprietary interest in its Confidential

         three years thereafter, all disclosures of Confidential Information to
         the receiving party, its agents and employees shall be held in strict
         confidence by such receiving party, its agents and employees, and such
         receiving party shall disclose the Confidential Information only to
         those of its agents and employees to whom it is necessary in order
         properly to carry out their duties as limited by the terms and
         conditions hereof. During the term of this Agreement and for a period
         of three years thereafter the receiving party shall not use the
         Confidential Information except for the purposes of exercising its
         rights and carrying out its duties hereunder. Upon the expiration or
         earlier termination of this Agreement, each party shall return to the
         other all Confidential Information and all copies thereof, and shall
         not at any time thereafter use any of such Confidential Information for
         any purpose. The provisions of this Section 6.1 shall also apply to any
         consultants or subcontractors during the term of this Agreement and for
         three years thereafter that the receiving party may engage in
         connection with its obligations under this Agreement. Before providing
         any Confidential Information to any such consultant or subcontractor,
         the receiving party shall obtain a signed undertaking in which such
         consultant or subcontractor agrees to be bound by and comply with terms
         substantially equivalent to and to the same effect as this Article 6.

              6.2 Liability for Disclosure. Notwithstanding anything contained
         in this Agreement to the contrary, neither party shall be liable for a
         disclosure of the other party's Confidential Information if the
         information so disclosed:

                   (a) was in the public domain at the time it was disclosed by
         the disclosing party to the receiving party; or

                   (b) was known to or contained in the records of the receiving
         party from a source other than the disclosing party at the time of
         disclosure by the disclosing party to the receiving party and can be so

                   (c) was independently developed by the receiving party and is
         so demonstrated promptly upon receipt of the documentation and

         than the disclosing party without breach of this Agreement by the
         receiving party and can be so demonstrated; or

         Information in accordance with Section 1.2 (Definition of Confidential
         Information) hereof; or

                   (f) must be disclosed pursuant to a contract or subcontract
         with a governmental agency in order to obtain/retain a procurement
         contract; or

                   (g) was disclosed pursuant to court order or as otherwise
         compelled by law.

         7.   "AS IS" CONDITION.

         OPERATING CAPABILITIES AND FUNCTIONALITY OF THE PRODUCTS AND LICENSEE

         authority to enter into this Agreement and there is nothing which would
         prevent it from performing its obligations under the terms and
         conditions imposed on it by this Agreement.

              8.2 Binding Obligation. This Agreement has been duly authorized by
         all necessary corporate and stockholder action of Licensor and
         Licensee, respectively, and constitutes a valid and binding obligation
         on Licensor and Licensee, respectively, enforceable in accordance with
         the terms hereof.

              8.3 Corporate Good Standing. Licensor or Licensee, as the case may
         be, is a corporation duly organized and validly existing and in good

         duly qualified and authorized to do business wherever the nature of its
         activities or properties requires such qualification or authorization.

<PAGE>   95
              8.4 No Government Approvals Needed. No registration with or
         approval of any government agency or commission of any jurisdiction is
         necessary for the execution, delivery or performance by it of any of
         the terms of this Agreement, or for the validity and enforceability
         hereof or with respect to its obligations hereunder.

              8.5 No Provisions Contravened. There is no provision in its
         company or corporate charter, articles of incorporation, By-Laws or
         equivalent governing documents, and no provision in any existing
         mortgage, indenture, contract or agreement binding on it which would be
         contravened by the execution, delivery or performance by it of this
         Agreement.

              8.6 No Consent of Third Parties Needed. No consent of any trustee
         or holder of any of its indebtedness is or shall be required as a
         condition to the validity of this Agreement.

              8.7 No Law Contravened. Neither its execution nor its delivery of

         jurisdiction, including, without limitation, any statute, rule,
         regulation, judgment, decree, order, franchise or permit applicable to
         it.

              8.8 Licensed Technology. Licensor has the right to use, and to
         grant licenses to use, the Licensed Technology. Licensor has not, and
         shall not in the future during the term of this Agreement, grant rights

         practicing under the Licensed Technology hereunder.

         other prior art which invalidate or would invalidate any of the patents
         included in the Licensed Technology, or issuance of any of those

         in the Licensed Technology was validly issued under the laws of the
         country which issued it.

              8.10 Continued Effect of Representations and Warranties. It
         covenants and agrees that its representations and warranties contained
         in this Agreement shall remain true in all respects for a period of one

         declared invalid or unenforceable by order of such court. The parties
         shall consult and use their best efforts to agree upon a valid and
         enforceable provision which shall be a reasonable substitute for such

         Agreement.

         to be due any person arising from the indemnitor's conduct with respect
         to this Agreement and the transactions contemplated herein.

                              Amended and Restated
                               BAY NETWORKS, INC.

                             1994 STOCK OPTION PLAN


         1.       Establishment and Purpose.

                  (a)      Establishment. The Wellfleet Communications, Inc.
1988 Stock Option Plan was adopted on January 20, 1988 (the "Initial Plan"). The
Initial Plan was amended and restated on May 16, 1991 and was renamed the
Wellfleet Communications, Inc. 1991 Restated Stock Option Plan (the "Prior
Plan"). In connection with the combination of Wellfleet Communications, Inc.
("Wellfleet") and SynOptics Communications, Inc. ("SynOptics") pursuant to the
Agreement and Plan of Merger dated as of July 4, 1994, as amended, by and among
Wellfleet, SynOptics, and a wholly owned subsidiary of Wellfleet, Wellfleet
intends to change its name to Bay Networks, Inc. The Prior Plan, as amended, is
amended and restated in its entirety and renamed the Bay Networks, Inc. 1994
Stock Option Plan (the "Plan").

                  (b)      Purpose. The purpose of the Plan is to secure for Bay
Networks, Inc. (the "Company") and its stockholders the benefits arising from
capital stock ownership by employees and officers of, and consultants or
advisors to, the Company and its parent and subsidiary corporations who are
expected to contribute to the Company's future growth and success. Except where
the context otherwise requires, the term "Company" shall include the parent and
all present and future subsidiaries of the Company as defined in Sections 424(e)
and 424(f) of the Internal Revenue Code of 1986, as amended or replaced from
time to time (the "Code"). Those provisions of the Plan which make express
reference to Section 422 shall apply only to Incentive Stock Options (as that
term is defined in the Plan).

         2.       Administration.

                  (a)      Administration by Board and/or Committee. The Plan
shall be administered by the Board of Directors of the Company (the "Board of
Directors") and/or by a duly appointed committee of the Board of Directors
having such powers as shall be specified by the Board of Directors. Any
subsequent references herein to the Board of Directors shall also mean the
committee if such committee has been appointed and, unless the powers of the
committee have been specifically limited, the committee shall have all of the
powers of the Board of Directors granted herein, including, without limitation,
the power to terminate or amend the Plan at any time, subject to the terms of
the Plan and any applicable limitations imposed by law. All questions of
interpretation of the Plan or of any options granted under the Plan (an
"Option") shall be determined by the Board of Directors, and such determinations
shall be final and binding upon all persons having an interest in the Plan
and/or any Option.

                  (b)      Disinterested Administration. With respect to the
participation in the Plan of employees who are also officers or directors of the
Company subject to Section 16 of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), the Plan shall be administered by the Board of Directors
in compliance with the "disinterested administration" requirement of Rule 16b-3,
as promulgated under the Exchange Act and amended from time to time or any
successor rule or regulation ("Rule 16b-3").


                                       1
<PAGE>   2
                  (c)      Compliance with Section 162(m) of the Code. In the
event a Participating Company is a "publicly held corporation" as defined in
paragraph (2) of Section 162(m) of the Code, as amended by the Revenue
Reconciliation Act of 1993 (P.L. 103-66), and the regulations promulgated
thereunder ("Section 162(m)"), the Company may establish a committee of outside
directors meeting the requirements of Section 162(m) to approve the grant of
Options which might reasonably be anticipated to result in the payment of
employee remuneration that would otherwise exceed the limit on employee
remuneration deductible for income tax purposes pursuant to Section 162(m).

                  (d)      Options Authorized. Options may be either incentive
stock options as defined in Section 422(a) of the Code ("Incentive Stock
Options") or nonstatutory options which are not intended to meet the
requirements of Section 422 of the Code.

                  (e)      Authority of Officers. Any officer of a Participating
Company shall have the authority to act on behalf of the Company with respect to
any matter, right, obligation, or election which is the responsibility of or
which is allocated to the Company herein, provided the officer has apparent
authority with respect to such matter, right, obligation, or election.

         3.       Eligibility.

                  Options may be granted to persons who are employees or
officers of, or consultants or advisors to, the Company. For purposes of the
foregoing sentence, "employees" or "officers" shall include prospective
employees or officers to whom Options are granted in connection with written
offers of employment with the Company and "consultants" or "advisors" shall
include prospective consultants or advisors to whom Options are granted in
connection with written consulting or advising offers with the Company. However,
Incentive Stock Options may be granted only to persons who are employees of the
Company at the time of the grant. A person who has been granted an option may,
if he or she is otherwise eligible, be granted additional options if the Board
of Directors shall so determine.

         4.       Stock Subject to Plan.

                  Options shall be for the purchase of shares of the authorized
but unissued Common Stock or treasury shares of Common Stock of the Company.
Subject to adjustment as provided in Section 15 below, the maximum number of
shares of Common Stock of the Company which may be issued and sold under the
Plan is forty-one million seven hundred thousand (41,700,000) shares. Subject to
adjustment as provided in Section 15 below, at any such time as the Company is a
"publicly held corporation" as defined in paragraph 2 of Section 162(m), no
person shall be granted within any fiscal year of the Company Options which in
the aggregate cover more than five hundred thousand (500,000) shares; provided,
however, that the foregoing limit shall be one million (1,000,000) shares with
respect to Options granted to any person during the first fiscal year of such
person's employment with the Company or upon the promotion of any person to an
executive office of the Company (the "Per Optionee Limit"). If an option granted
under the Plan shall expire or terminate for any reason without having been
exercised in full and/or shares of Common Stock subject to repurchase are
repurchased by the Company, the unpurchased shares subject to such option or
such repurchased shares shall again be available for subsequent option grants
under the Plan. Notwithstanding the foregoing, any such shares shall be made
subject to a new Option only if the grant of such new Option and the issuance of
such shares pursuant to such new Option would not cause the Plan or any Option
granted under the Plan to contravene Rule 16b-3.


                                       2
<PAGE>   3
         5.       Forms of Option Agreements.

                  As a condition to the grant of an option under the Plan, each
recipient of an option shall execute an option agreement in such form not
inconsistent with the Plan as may be approved by the Board of Directors. Such
option agreements may differ among recipients.

         6.       Purchase Price.

                  (a)      General. The purchase price per share of stock
deliverable upon the exercise of an option shall be determined by the Board of
Directors, provided, however, that the exercise price shall not be less than
100% of the fair market value of such stock, as determined by the Board of
Directors, at the time of grant of such option, or less than 110% of such fair
market value in the case of options described in Section 11(b).

                  (b)      Payment of Purchase Price. Options granted under the
Plan may provide for the payment of the exercise price by delivery of cash or a
check to the order of the Company in an amount equal to the exercise price of
such options, or, to the extent provided in the applicable option agreement, (i)
by delivery to the Company of shares of Common Stock of the Company already
owned by the optionee having a fair market value equal in amount to the exercise
price of the options being exercised, (ii) by any other means (including,
without limitation, by delivery of a promissory note of the optionee payable on
such terms as are specified by the Board of Directors) which the Board of
Directors determines are consistent with the purpose of the Plan and with
applicable laws and regulations (including, without limitation, the provisions
of Rule 16b-3 and Regulation T promulgated by the Federal Reserve Board) or
(iii) by any combination of such methods of payment. The fair market value of
any shares of the Company's Common Stock or other non-cash consideration which
may be delivered upon exercise of an option shall be determined by the Board of
Directors.

         7.       Option Period.

                  Each option and all rights thereunder shall expire on such
date as shall be set forth in the applicable option agreement, except that, in
the case of an Incentive Stock Option, such date shall not be later than ten
years after the date on which the option is granted and, in all cases, options
shall be subject to earlier termination as provided in the Plan.

         8.       Exercise of Options.

                  Each option granted under the Plan shall be exercisable either
in full or in installments at such time or times and during such period as shall
be set forth in the agreement evidencing such option, subject to the provisions
of the Plan.

         9.       Nontransferability of Options.

                  Unless otherwise provided by the Board of Directors at the
time of grant, during the lifetime of the optionee, the Option shall be
exercisable only by the optionee and no Option shall be assignable or
transferable by the optionee, either voluntarily or by operation of law, except
by will or the laws of descent and distribution; provided, however, that
nonstatutory options may be transferred pursuant to a qualified domestic
relations order (as defined in Rule 16b-3).

                                       3
<PAGE>   4
         10.      Effect of Termination of Employment or Other Relationship.

                  Except as provided in Section 11(d) with respect to Incentive
Stock Options, and subject to the provisions of the Plan, the Board of Directors
shall determine the period of time during which an optionee may exercise an
option following (i) the termination of the optionee's employment or other
relationship with the Company or (ii) the death or disability of the optionee.
Such periods shall be set forth in the agreement evidencing such option.

         11.      Incentive Stock Options.

                  Options granted under the Plan which are intended to be
Incentive Stock Options shall be subject to the following additional terms and
conditions:

                  (a)      Express Designation. All Incentive Stock Options
granted under the Plan shall, at the time of grant, be specifically designated
as such in the option agreement covering such Incentive Stock Options.

                  (b)      10% Stockholder. If any employee to whom an Incentive
Stock Option is to be granted under the Plan is, at the time of the grant of
such option, the owner of stock possessing more than 10% of the total combined
voting power of all classes of stock of the Company (after taking into account
the attribution of stock ownership rules of Section 424(d) of the Code), then
the following special provisions shall be applicable to the Incentive Stock
Option granted to such individual:

                           (i) The purchase price per share of the Common Stock
subject to such Incentive Stock Option shall not be less than 110% of the fair
market value of one share of Common Stock at the time of grant; and

                           (ii)     the option exercise period shall not exceed
five years from the date of grant.

                  (c)      Dollar Limitation. For so long as the Code shall so
provide, options granted to any employee under the Plan (and any other incentive
stock option plans of the Company) which are intended to constitute Incentive
Stock Options shall not constitute Incentive Stock Options to the extent that
such options, in the aggregate, become exercisable for the first time in any one
calendar year for shares of Common Stock with an aggregate fair market value
(determined as of the respective date or dates of grant) of more than $100,000.

                  (d)      Termination of Employment, Death or Disability. No
Incentive Stock Option may be exercised unless, at the time of such exercise,
the optionee is, and has been continuously since the date of grant of his or her
option, employed by the Company, except that:

                           (i)      an Incentive Stock Option may be exercised
within the period of three months after the date the optionee ceases to be an
employee of the Company (or within such lesser period as may be specified in the
applicable option agreement), provided, that the agreement with respect to such
option may designate a longer exercise period and that the exercise after such
three-month period shall be treated as the exercise of a non-statutory option
under the Plan;

                           (ii)     if the optionee dies while in the employ of
the Company, or within three months after the optionee ceases to be such an
employee, the Incentive Stock Option may be exercised by the person to whom it
is transferred by will or the laws of descent and distribution

                                       4
<PAGE>   5
within the period of one year after the date of death (or within such lesser
period as may be specified in the applicable option agreement); and

                           (iii)    if the optionee becomes disabled (within the
meaning of Section 22(e)(3) of the Code or any successor provision thereto)
while in the employ of the Company, the Incentive Stock Option may be exercised
within the period of one year after the date the optionee ceases to be such an
employee because of such disability (or within such lesser period as may be
specified in the applicable option agreement).

For all purposes of the Plan and any option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the
Income Tax Regulations (or any successor regulations). Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.

         12.      Additional Provisions.

                  (a)      Additional Option Provisions. The Board of Directors
may, in its sole discretion, include additional provisions in option agreements
covering options granted under the Plan, including without limitation,
restrictions on transfer, repurchase rights, commitments to pay cash bonuses, to
make, arrange for or guaranty loans or to transfer other property to optionees
upon exercise of options, or such other provisions as shall be determined by the
Board of Directors; provided that such additional provisions shall not be
inconsistent with any other term or condition of the Plan and such additional
provisions shall not cause any Incentive Stock Option granted under the Plan to
fail to qualify as an Incentive Stock Option within the meaning of Section 422
of the Code.

                  (b)      Acceleration, Extension. Etc. The Board of Directors
may, in its sole discretion, (i) accelerate the date or dates on which all or
any particular option or options granted under the Plan may be exercised or (ii)
extend the dates during which all, or any particular, option or options granted
under the Plan may be exercised; provided, however, that no such extension shall
be permitted if it would cause the Plan to fail to comply with Section 422 of
the Code or with Rule 16b-3.

         13.      Compliance With Securities Laws.

                  Each option shall be subject to the requirement that if, at
any time, counsel to the Company shall determine that the listing, registration
or qualification of the shares subject to such option upon any securities
exchange or under any state or federal law, or the consent or approval of any
governmental or regulatory body, or that the disclosure of non-public
information or the satisfaction of any other condition is necessary as a
condition of, or in connection with, the issuance or purchase of shares
thereunder, such option may not be exercised, in whole or in part, unless such
listing, registration, qualification, consent or approval, or satisfaction or
such condition shall have been effected or obtained on conditions acceptable to
the Board of Directors. Nothing herein shall be deemed to require the Company to
apply for or to obtain such listing, registration or qualification, or to
satisfy such condition.

         14.      Rights as a Stockholder.

                  The holder of an option shall have no rights as a stockholder
with respect to any shares covered by the option (including, without limitation,
any rights to receive dividends or

                                       5
<PAGE>   6
non-cash distributions with respect to such shares) until the date of issue of a
stock certificate to him or her for such shares. No adjustment shall be made for
dividends or other rights for which the record date is prior to the date such
stock certificate is issued.

         15.      Adjustment Provisions for Recapitalizations and Related
Transactions.

                  (a)      General. If, through or as a result of any merger,
consolidation, sale of all or substantially all of the assets of the Company,
reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split or other similar transaction, (i) the outstanding shares of
Common Stock are increased, decreased or exchanged for a different number or
kind of shares or other securities of the Company, or (ii) additional shares or
new or different shares or other securities of the Company or other non-cash
assets are distributed with respect to such shares of Common Stock or other
securities, an appropriate and proportionate adjustment may be made in (1) the
maximum number and kind of shares reserved for issuance under the Plan, (2) the
maximum number and kind of shares described in the Per Optionee Limit, (3) the
number and kind of shares or other securities subject to any then outstanding
options under the Plan, and (4) the price for each share subject to any then
outstanding options under the Plan, without changing the aggregate purchase
price as to which such options remain exercisable. Notwithstanding the
foregoing, no adjustment shall be made pursuant to this Section 15 if such
adjustment would cause the Plan to fail to comply with Section 422 of the Code
or with Rule 16b-3.

                  (b)      Board Authority to Make Adjustments. Any adjustments
under this Section 15 will be made by the Board of Directors, whose
determination as to what adjustments, if any, will be made and the extent
thereof will be final, binding and conclusive. No fractional shares will be
issued under the Plan on account of any such adjustments.

         16.      Merger, Consolidation, Asset Sale, Liquidation, etc.

                  (a)      General. In the event of a consolidation or merger or
sale of all or substantially all of the assets of the Company in which
outstanding shares of Common Stock are exchanged for securities, cash or other
property of any other corporation or business entity or in the event of a
liquidation of the Company, the Board of Directors of the company, or the board
of directors of any corporation assuming the obligations of the Company, may, in
its discretion, take any one or more of the following actions, as to outstanding
options: (i) provide that such options shall be assumed, or equivalent options
shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof), provided that any such options substituted for Incentive
Stock Options shall meet the requirements of Section 424(a) of the Code, (ii)
upon written notice to the optionees, provide that all unexercised options will
terminate immediately prior to the consummation of such transaction unless
exercised by the optionee within a specified period following the date of such
notice, (iii) in the event of a merger under the terms of which holders of the
Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the merger (the "Merger Price"), make or
provide for a cash payment to the optionees equal to the difference between (A)
the Merger Price times the number of shares of Common Stock subject to such
outstanding options (to the extent then exercisable at prices not in excess of
the Merger Price) and (B) the aggregate exercise price of all such outstanding
options in exchange for the termination of such options, and (iv) provide that
all or any outstanding options shall become exercisable in full immediately
prior to such event.



                                       6
<PAGE>   7
                  (b)      Substitute Options. The company may grant options
under the Plan in substitution for options held by employees of another
corporation who become employees of the Company, or a subsidiary of the Company,
as the result of a merger or consolidation of the employing corporation with the
Company or a subsidiary of the Company, or as a result of the acquisition by the
Company, or one of its subsidiaries, of property or stock of the employing
corporation. The Company may direct that substitute options be granted on such
terms and conditions as the Board of Directors considers appropriate in the
circumstances.

         17.      No Special Employment Rights.

                  Nothing contained in the Plan or in any option shall confer
upon any optionee any right with respect to the continuation of his or her
employment by the Company or interfere in any way with the right of the Company
at any time to terminate such employment at any time or to increase or decrease
the compensation of the optionee.

         18.      Other Employee Benefits.

                  Except as to plans which by their terms include such amounts
as compensation, the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares received
upon such exercise will not constitute compensation with respect to which any
other employee benefits of such employee are determined, including, without
limitation, benefits under any bonus, pension, profit-sharing, life insurance or
salary continuation plan, except as otherwise specifically determined by the
Board of Directors.

         19.      Amendment of the Plan.

                  (a)      The Board of Directors may at any time, and from time
to time, modify or amend the Plan in any respect, provided, however, that
without the approval of the Company's stockholders, there shall be (i) no
increase in the total number of shares of Stock covered by the Plan (except by
operation of the provisions of paragraph 9 above), (ii) no change in the class
of persons eligible to receive Incentive Stock Options, and (iii) no expansion
in the class of persons eligible to receive nonstatutory options. In addition to
the foregoing, if at any time the approval of the stockholders of the Company is
required under Section 422 of the Code or any successor provision with respect
to Incentive Stock Options, or in order to comply with Rule 16b-3, the Board of
Directors may not effect such modification or amendment without such approval.

                  (b)      The termination or any modification or amendment of
the Plan shall not, without the consent of an optionee, affect his or her rights
under an option previously granted to him or her. With the consent of the
optionee affected, the Board of Directors may amend outstanding option
agreements in a manner not inconsistent with the Plan. The Board of Directors
shall have the right to amend or modify (i) the terms and provisions of the Plan
and of any outstanding Incentive Stock Options granted under the Plan to the
extent necessary to qualify any or all such options for such favorable federal
income tax treatment (including deferral of taxation upon exercise) as may be
afforded incentive stock options under Section 422 of the Code and (ii) the
terms and provisions of the Plan and of any outstanding option to the extent
necessary to ensure the qualification of the Plan under Rule 16b-3.

         20.      Withholding.



                                       7
<PAGE>   8
                  (a)      The Company shall have the right to deduct from
payments of any kind otherwise due to the optionee any federal, state or local
taxes of any kind required by law to be withheld with respect to any shares
issued upon exercise of options under the Plan. Subject to the prior approval of
the Company, which may be withheld by the Company in its sole discretion, the
optionee may elect to satisfy such obligations, in whole or in part, (i) by
causing the Company to withhold shares of Common Stock otherwise issuable
pursuant to the exercise of an option or (ii) by delivering to the Company
shares of Common Stock already owned by the optionee. The shares so delivered or
withheld shall have a fair market value equal to such withholding obligation.
The fair market value of the shares used to satisfy such withholding obligation
shall be determined by the Company as of the date that the amount of tax to be
withheld is to be determined. An optionee who has made an election pursuant to
this Section 20(a) may only satisfy his or her withholding obligation with
shares of Common Stock which are not subject to any repurchase, forfeiture,
unfulfilled vesting or other similar requirements.

                  (b)      Notwithstanding the foregoing, in the case of a
person required to file reports under Section 16(a) of the Exchange Act, no
election to use shares for the payment of withholding taxes shall be effective
unless made in compliance with any applicable requirements of Rule 16b-3.

         21.      Cancellation and New Grant of Options, Etc.

                  The Board of Directors shall have the authority to effect, at
any time and from time to time, with the consent of the affected optionees, (i)
the cancellation of any or all outstanding options under the Plan and the grant
in substitution therefor of new options under the Plan covering the same or
different numbers of shares of Common Stock and having an option exercise price
per share which may be lower or higher than the exercise price per share of the
cancelled options or (ii) the amendment of the terms of any and all outstanding
options under the Plan to provide an option exercise price per share which is
higher or lower than the then-current exercise price per share of such
outstanding options.

         22.      Termination of the Plan.

                  Unless sooner terminated in accordance with Section 16, the
Plan shall terminate, with respect to Incentive Stock Options, upon the earlier
of (i) May 15, 2001, or (ii) the date on which all shares available for issuance
under the Plan have been issued pursuant to the exercise or cancellation of
options granted under the Plan. Unless sooner terminated in accordance with
Section 16, the Plan shall terminate with respect to options which are not
Incentive Stock Options on the date specified in (ii) above. If the date of
termination is determined under (i) above, then options outstanding on such date
shall continue to have force and effect in accordance with the provisions of the
instruments evidencing such options.

                  Notwithstanding any other provision to the contrary, the
Initial Plan and the Prior Plan shall remain in effect in accordance with their
terms and apply to Options granted pursuant to the Initial Plan and the Prior
Plan, respectively.

         23.      Provision for Foreign Participants.

                  The Board of Directors may, without amending the Plan, modify
awards or options granted to participants who are foreign nationals or employed
outside the United States to 

                                       8
<PAGE>   9
recognize differences in laws, rules, regulations or customs of such foreign
jurisdictions with respect to tax, securities, currency, employee benefit or
other matters.

         IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies
that the foregoing Bay Networks, Inc. 1994 Stock Option Plan was duly adopted by
the Board of Directors of the Company on the 17th day of August, 1994.

                                  THE COMPANY

         Bay Networks, Inc., a Delaware corporation (the "Company"), is the
issuer of the shares of Common Stock covered by this Prospectus. Its principal
offices are located at 4401 Great America Parkway, Santa Clara, California and
its telephone number is (408) 988-2400. The Company was formerly named Wellfleet
Communications, Inc.

                    DESCRIPTION OF THE 1994 STOCK OPTION PLAN

         The Wellfleet Communications, Inc. 1988 Stock Option Plan was adopted
on January 20, 1988 (the "1988 Plan"). The 1988 Plan was amended and restated on
May 16, 1991 and was renamed the Wellfleet Communications, Inc. 1991 Restated
Stock Option Plan (the "1991 Plan"). The 1991 Plan was amended and restated
pursuant to the terms of the Agreement and Plan of Merger dated as of July 4,
1994, as amended, by and among Wellfleet Communications, Inc., SynOptics
Communications, Inc. and Spoke Merger Co., Inc., and renamed the Bay Networks,
Inc. 1994 Stock Option Plan (the "Plan"). The Plan was approved by the
shareholders on October 20, 1994. The Plan provides for the grant of options
which will qualify as "incentive stock options" under Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code") and nonstatutory options.

         The purpose of the Plan is to secure for the Company and its
shareholders the benefits arising from capital stock ownership by employees and
officers of, and consultants and advisors to the Company and its subsidiary
corporations who are expected to contribute to the Company's future growth and
success.

         The following is a brief summary of the provisions of the Plan. This
summary is qualified in all respects by reference to the full text of the Plan,
which the Company will provide, without charge, upon written or oral request of
any person to whom this Prospectus is delivered. Each person granted an option
under the Plan should also carefully review his or her option agreement.

SHARES SUBJECT TO THE PLAN

         A total of 41,700,000 shares of Common Stock are reserved for issuance
pursuant to the Plan. If the outstanding shares of the Common Stock of the
Company are changed by reason of recapitalization, reclassification, stock
dividend, stock split, reverse stock split or other similar change in the
Company's capital stock, the Board may appropriately adjust the maximum number
of shares reserved for issuance under the Plan, the "Per Employee Limit" as
defined below, the number and kind of shares subject to any then outstanding
options and the price for each share subject to any then outstanding options
without changing the aggregate purchase price as to which such options remain
exercisable.

         Shares issued under the Plan consist of authorized but unissued shares
or treasury shares. If an option granted under the Plan expires or terminates
without having been exercised in full and/or shares of Common Stock subject to
repurchase are repurchased by the Company, the unpurchased shares subject to
such option or such repurchased shares shall again be available for subsequent
option grants under the Plan, provided, however, that the grant of such new
option would not cause the Plan or any option under the Plan to contravene Rule
16b-3 under the Securities Exchange Act of 1934 or any successor provision
("Rule 16b-3").

ADMINISTRATION OF THE PLAN

         The Plan is administered by the Board of Directors of the Company (the
"Board"). The directors are elected by the shareholders of the Company in
accordance with the provisions of the Certificate of Incorporation and the
By-Laws of the Company. All questions of interpretation of the Plan or of any
options granted under the Plan shall be determined by the Board of Directors.
The Board's decisions are final and binding.

         To the extent permitted by applicable law, the Board may appoint a
committee to administer the Plan (the "Committee") and, in such event, all
references to the Board in this prospectus shall mean such Committee or the
Board. Said Committee must be comprised of not less than two members of the
Board appointed by the Board to administer the Plan, provided that each member
of the Committee shall be a "disinterested person" within the meaning of Rule
16b-3.

         The Company may establish a committee of outside directors meeting the
requirements of Section 162(m) of the Code ("Section 162(m)") to approve the
grant of options which might reasonably be anticipated to result in the payment
of employee renumeration that would otherwise exceed the limit on employee
renumeration deductible for income tax purposes pursuant to Section 162(m).

INCENTIVE STOCK OPTIONS AND NONSTATUTORY OPTIONS

         The Plan provides for the grant of incentive stock options and
nonstatutory options. Incentive stock options are intended to satisfy the
requirements of Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code").

         Option Agreement. Each optionee shall be required to execute an option
agreement in such form as may be approved by the Board. The Board may include
additional provisions in option agreements, including without limitation,
restrictions on transfer, repurchase rights, commitments to pay cash bonuses, to
make, arrange for or guaranty loans or to transfer other property to optionees
upon exercise of option, provided that such additional provisions shall not be
inconsistent with the Plan or cause any incentive stock option to fail to
qualify under Section 422 of the Code.

         Option Exercise Price. Optionees will receive the right to purchase a
specified number of shares of the Common Stock of the Company at some time in
the future at an option price determined by the Board at the time of grant. This
price may not be less than 100% of the fair market value of the Common Stock of
the Company on the date of the grant or less than 110% of the fair market value
in the case of incentive stock options exercised by an employee who is a 10%
shareholder of the Company at the time of the grant.

         Duration and Exercise of Option. Each option shall be exercisable and
shall vest at such times and subject to such conditions as the Board may
specify. The Board may at any time accelerate the time at which all or any part
of an option may be exercised or vest. Generally, Options are immediately
exercisable in full on the date of grant, subject to the Company's unvested
share repurchase option as described below. Any option granted as an incentive
stock option must be in compliance with the requirements of Section 422 of the
Code or any statutory provision which may replace such section and any
regulations thereunder. Accordingly, no incentive stock 


                                       2
<PAGE>   17
option exercise period shall exceed ten years from the date of grant, and the
exercise period shall not exceed five years if the employee is a 10% shareholder
of the Company at the time of the grant.

         Terms of Payment. Options granted under the Plan may provide for the
payment of the exercise price by delivery of cash or check in an amount equal to
the exercise price of such options or, to the extent permitted by the applicable
option agreement (and subject, in the case of incentive stock options, to any
limitation required under the Code), by (A) delivery of shares of Common Stock
owned by the optionee, valued at their fair market value, (B) any other means
which the Board determines are consistent with the purpose of the Plan and with
applicable laws and regulations or (C) any combination of the foregoing.

         Termination of Employment. The Board shall determine the period of time
during which an optionee may exercise an option following the termination of the
optionee's employment or other relationship with the Company or the optionee's
death or disability. No incentive stock option may be exercised unless, at the
time of such exercise, the optionee is, and has been continuously since the date
of grant of his or her option, employed by the Company, except that:

                  (a)      an incentive stock option may be exercised
within the period of three months after the date the optionee ceases to be an
employee of the Company (or within such lesser period as may be specified in the
applicable option agreement), provided, that the agreement with respect to such
option may designate a longer exercise period and that the exercise after such
three-month period shall be treated as the exercise of a nonstatutory stock
option under the Plan;

                  (b)      if the optionee dies while in the employ of the
Company, or within three months after the optionee ceases to be such an
employee, the incentive stock option may be exercised by the person to whom it
is transferred by will or the laws of descent and distribution within the period
of one year after the date of death (or within such lesser period as may be
specified in the applicable option agreement); and

                  (c)      if the optionee becomes disabled (within the meaning
of Section 22(e)(3) of the Code or any successor provision thereto) while in the
employ of the Company, the incentive stock option may be exercised within the
period of one year after the date the optionee ceases to be such an employee
because of such disability (or within such lesser period as may be specified in
the option agreement).

Notwithstanding the foregoing provisions, no stock option may be exercised after
its expiration date.

         Additional Limitations on Incentive Stock Options. In addition to the
provisions concerning incentive stock options which are described above, options
granted under the Plan which are intended to be incentive stock options shall be
subject to the following additional terms and conditions:

                  (a)      All incentive stock options granted under the Plan
shall, at the time of grant, be specifically designated as such in the option
agreement covering such incentive stock options.

                  (b)      For so long as the Code shall so provide, options
granted to any employee under the Plan (and any other incentive stock option
plans of the Company) which are intended to


                                       3
<PAGE>   18
constitute incentive stock options will not constitute incentive stock options
to the extent that such options, in the aggregate, become exercisable for the
first time in any one calendar year for shares of Common Stock with an aggregate
fair market value (determined as of the respective date or dates of grant) of
more than $100,000.

         Unvested Share Repurchase Option. Generally, shares acquired upon the
exercise of an option which are not vested are subject to the right of the
Company to repurchase a certain number of the shares at their original cost per
share upon termination of the optionee's employment with the Company for any
reason, with or without cause, or if the optionee (or the optionee's legal
representative) attempts to sell, exchange, transfer, pledge, or otherwise
dispose of any shares acquired on the exercise of an option before such shares
have vested (the "Unvested Share Repurchase Option"). The number of shares
subject to the Unvested Share Repurchase Option decreases over time, as the
shares vest. Usually, one quarter of the shares will be vested on the Initial
Vesting Date, which means the date occurring one year after the date on which
the optionee commenced employment with the Company or one year from the grant
date, and for each full month of continuous service with the Company completed
by the optionee after the Initial Vesting Date, the shares will be vested at a
rate of one-forty-eighth per month. The vesting schedule for any option grant is
set at the discretion of the Board, and is determined at the time that the grant
is made. The vesting schedule will be set out in the option agreement for each
grant.

         To insure that the unvested shares will be available for repurchase,
the optionee must deposit the certificates evidencing the shares which the
optionee purchases upon exercise of an option with an escrow agent designated by
the Board under the terms and conditions of an escrow agreement approved by the
Board. The Company will bear the expenses of the escrow.

         The Company may exercise the Unvested Share Repurchase Option by
written notice to the escrow agent and to the optionee or the optionee's legal
representative within sixty days after such termination of employment (or
exercise of the option, if later) or after the Company has received notice of
the attempted disposition. If the Company fails to give notice within such sixty
day period, the Unvested Share Repurchase Option will terminate unless the
Company and the optionee have extended the time for the exercise of the Unvested
Share Repurchase Option. The Unvested Stock Repurchase Option must be exercised,
if at all, for all of the unvested shares except as the Company and the optionee
otherwise agree.

         Payment by the Company to the escrow agent on behalf of the optionee or
the optionee's legal representative will be made in cash within thirty days
after the date of the mailing of the written notice of exercise of the Unvested
Share Repurchase Option. Cancellation of any promissory note of the optionee to
any Company will be treated as payment to the optionee in cash to the extent of
the unpaid principal and any accrued interest canceled. Within thirty days after
payment by the Company, the escrow agent will deliver the shares which the
Company has purchased to the Company and will deliver the payment received from
the Company to the optionee.

         The Company may assign the Unvested Share Repurchase Option at any
time, whether or not such option is then exercisable, to one or more persons as
may be selected by the Board.

         The Unvested Share Repurchase Option will not apply to a transfer to
the optionee's ancestors, descendants or spouse or to a trustee for the benefit
of the optionee or the optionee's ancestors, descendants or spouse, provided
that such transferee agrees in writing (in a form 


                                       4
<PAGE>   19
satisfactory to the Board) to take the shares subject to all the terms and
conditions of the Unvested Shares Repurchase Option.

         As soon as practicable after the expiration of the Unvested Share
Repurchase Option and after full repayment on any promissory note secured by the
shares in escrow, the escrow agent will deliver to the optionee the shares no
longer subject to such restriction and no longer security for any promissory
note.

ELIGIBILITY

         Under the terms of the Plan, all employees and officers of and
consultants and advisors to the Company or any subsidiary who are expected to
contribute to the Company's future growth and success, are eligible for the
grant of options under the Plan. For the purposes of the foregoing sentence,
"employees" or "officers" shall include prospective employees or officers to
whom options are granted in connection with written offers of employment with
the Company and "consultants" or "advisors" shall include prospective
consultants or advisors to whom options are granted in connection with written
consulting or advising offers with the Company. Incentive stock options may be
awarded only to persons eligible to receive such options under the Code. Options
may be granted to employees who are foreign nationals or employed outside the
United States on such terms different from those specified in the Plan as may,
in the judgment of the Board, be necessary or advisable to achieve the purposes
of the Plan or comply with applicable laws.

GENERAL RESTRICTIONS

         For so long as the Company is a "publicly held corporation" as defined
in Section 162(m), no person may be granted within any fiscal year options which
in the aggregate cover more than 500,000 shares, provided, however, that this
limit shall be 1,000,000 shares with respect to options granted to any person
during the first fiscal year of such person's employment with the Company or
upon the promotion of any person to an executive office of the Company (the "Per
Optionee Limit").

         An option granted under the Plan may not be exercised (i) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulations have been complied with, (ii) if the outstanding stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized to be listed on such exchange upon official notice of
notice of issuance, and (iii) until all other legal matters in connection with
the issuance and delivery of such shares have been approved by the Company's
counsel.

         No person shall have any claim or right to be granted an option under
the Plan, and the grant of an option shall not be construed as giving an
optionee the right to continued employment or service for the Company. The
Company expressly reserves the right at any time to dismiss an optionee free
from any liability or claim under the Plan, except as expressly provided in the
applicable option agreement.

         Subject to the provisions of the applicable option, no optionee shall
have any rights as a shareholder with respect to any shares of Common Stock to
be distributed under the Plan until he or she becomes the record holder thereof.


                                       5
<PAGE>   20
NONTRANSFERABILITY

         Unless otherwise provided by the Board at the time of grant, during the
lifetime of the optionee, the option shall be exercisable only by the optionee
and no option may be assignable or transferable by the optionee except by will
or the laws of descent and distribution. However, nonstatutory options may be
transferred pursuant to a qualified domestic relations order (as defined in Rule
16b-3).

EFFECTIVE DATE, TERMINATION AND AMENDMENT

         The Plan was approved by the shareholders of the Company on October 20,
1994, and became effective on that date.

         The Plan will terminate, with respect to incentive stock options upon
the earlier of (i) May 15, 2001, or (ii) the date on which all shares available
for issuance under the Plan have been issued pursuant to the exercise or
cancellation of options granted under the Plan, and with respect to nonstatutory
options on the date specified in (ii). If the Plan is terminated on May 15, 2001
then options outstanding on that date shall continue to have force and effect in
accordance with the provisions of the instruments evidencing such options.

         The Board may amend the Plan at any time and in any respect provided,
however, that without the approval of the Company's shareholders there shall be
(i) no increase in the total number of shares covered by the Plan, (ii) no
change in the class of persons eligible to receive incentive stock options and
(iii) no expansion in the class of persons eligible to receive nonstatutory
options. The termination or amendment of the Plan shall not affect an optionee's
rights under an option previously granted, without the consent of the optionee.
With such consent the Board may amend outstanding option agreements in a manner
not inconsistent of the Plan. The Board may amend or modify the terms and
provisions of the Plan and any incentive stock option granted under the Plan to
the extent necessary to qualify such options for favorable income tax treatment
under Section 422 of the Code and to ensure the qualification of the Plan under
Rule 16b-3. Further, no amendment may be made without shareholder approval if
such approval is required under Section 422 of the Code or any successor
provision with respect to incentive stock options or is necessary to comply with
Rule 16b-3.

CONSOLIDATION, MERGER OR OTHER REORGANIZATION

         In the event of a consolidation or merger or sale of all or
substantially all of the assets of the Company in which outstanding shares of
Common Stock are exchanged for securities, cash or other property of any other
entity or in the event of a liquidation of the Company, the Board, or the board
of directors of any corporation assuming the obligations of the Company, may, in
its discretion, take any one or more of the following actions as to outstanding
options: (i) provide that such options shall be assumed, or equivalent options
shall be substituted, by the acquiring or succeeding corporation provided that
any options substituted for incentive stock options shall meet the requirements
of Section 424(a) of the Code, (ii) upon written notice to the optionees,
provide that all unexercised options will terminate immediately prior to the
consummation of such transaction unless exercised by the optionee within a
specified period, (iii) in the event of a merger under the terms of which
holders of the Common Stock of the Company will receive upon consummation
thereof a cash payment for each share surrendered in the merger (the "Merger
Price"), make or provide for a specified cash payment to the optionees equal to
the difference 


                                       6
<PAGE>   21
between (A) the Merger Price times the number of shares of Common Stock subject
to such outstanding options (to the extent then vested at prices not in excess
of the Merger Price) and (B) the aggregate exercise price of all such
outstanding options in exchange for the termination of such options, and (iv)
provide that all or any outstanding options will become vested in full prior to
the effective date of such event.

         The Company may grant options under the Plan in substitution for
options held by employees of another corporation who become employees of the
Company or a subsidiary of the Company as a result of a merger or consolidation
of the employing corporation with the Company or a subsidiary of the Company or
as a result of the acquisition by the Company or one of its subsidiaries of
property or stock of the employing corporation. The substitute options shall be
granted on such terms and conditions as the Board considers appropriate in the
circumstances.

 FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary of the federal income tax treatment of
options granted under the Plan. The tax consequences recognized by an optionee
may vary; therefore, an optionee should consult his or her tax advisor for
advice concerning any specific transaction.

         Incentive Stock Options. No taxable income will be recognized by an
optionee upon the grant or exercise of an incentive stock option granted under
the Plan (provided that the difference between the option exercise price and the
fair market value of the stock on the date of exercise must be included in the
optionee's "alternative minimum taxable income" as described below), and no
corresponding expense deduction will be available to the Company. Generally, if
an optionee holds shares acquired upon the exercise of incentive stock options
until the later of (i) two years from the grant of the option and (ii) one year
from the date of transfer of the purchased shares to him or her (the "Statutory
Holding Period"), any gain to the optionee upon a sale of such shares will be
treated as capital gain. The gain recognized upon the sale of the stock is the
difference between the option price and the sale price of the stock. The net
federal income tax effect on the holder of incentive stock options is to defer,
until the stock is sold, taxation of any increase in the stock's value from the
time of grant to the time of exercise, and to cause all such increase to be
treated as capital gain.

         If the optionee sells the shares prior to the expiration of the
Statutory Holding Period (a "disqualifying disposition"), he or she will realize
taxable income at ordinary income tax rates in an amount equal to the lesser of
(i) the fair market value of the shares on the date of exercise less the option
price, or (ii) the amount realized on the sale less the option price, and the
Company will receive a corresponding business expense deduction. Any additional
gain will be treated as long-term capital gain if the shares are held for more
than one year prior to the sale and as short-term capital gain if the shares are
held for a shorter period. If the optionee sells the stock for less than the
option price, he or she will recognize a capital loss equal to the difference
between the sale price and the option price. The loss will be a long-term
capital loss if the shares are held for more than one year prior to the sale and
as a short-term capital loss if the shares are held for a shorter period.

         Special rules may apply to options held by directors and officers. If
the optionee making a disqualifying disposition is a person required to file
reports pursuant to Section 16 of the Exchange Act or any successor provision (a
"Reporting Person"), and the option was exercised within six months of the date
of grant, the amount of taxable income realized at ordinary income tax rates
(and the amount of the Company's business expense deduction) will be equal to
the lesser of (i) 


                                       7
<PAGE>   22
the fair market value of the shares on the date that is six months after the
date of grant less the option price, or (ii) the amount realized on sale less
the option price.

         For purposes of the "alternative minimum tax" applicable to
individuals, the exercise of an incentive stock option is treated in the same
manner as the exercise of a nonstatutory option. Thus, an optionee must, in the
year of option exercise, include the difference between the exercise price and
the fair market value of the stock on the date of exercise in alternative
minimum taxable income. The alternative minimum tax is imposed upon an
individual's alternative minimum taxable income currently at rates of 26% to
28%, but only to the extent that such tax exceeds the taxpayer's regular income
tax liability for the taxable year.

         Nonstatutory Stock Options. No taxable income is recognized by the
optionee upon the grant of a nonstatutory option. The optionee must recognize as
ordinary income in the year in which the option is exercised the amount by which
the fair market value of the purchased shares on the date of exercise exceeds
the option price (and the Company is required to withhold an appropriate amount
for tax purposes). However, the following special rules apply to Reporting
Persons. If a Reporting Person exercises the option within six months of the
date of grant, upon exercise of such option no income will be recognized by the
optionee until six months have expired from the date the option was granted, and
the income then recognized will include any appreciation in the value of the
shares during the period between the date of exercise and the date six months
after the date of grant, unless the optionee makes an election under Section 
83(b) of the Code to have the difference between the exercise price and fair
market value at the time of exercise recognized as ordinary income as of the
time of exercise.

         The Company will be entitled to a business expense deduction equal to
the amount of ordinary income recognized by the optionee. Any additional gain or
any loss recognized upon the subsequent disposition of the purchased shares will
be a capital gain or loss, and will be a long-term gain or loss if the shares
are held for more than one year.

         This tax summary is general and does not apply to gifts or any
dispositions other than sales. Also, under certain circumstances, a grantee may
be entitled to a credit for alternative minimum tax already paid. In addition,
in some individual cases, it will be important to consider the state and foreign
tax consequences of participation in the Plan and the effect, if any, of gift,
estate and inheritance taxes. For advice as to your specific situation, you
should consult your tax advisor.

WITHHOLDING

         The Company shall have the right to deduct from payments due to the
optionee any taxes required by law to be withheld with respect to any shares
issued upon the exercise of options granted under the Plan. In the Board's
discretion, and subject to such conditions as the Board may establish, such tax
obligations may be paid in whole or in part in shares of Common Stock, including
shares retained from the exercise of an option creating the tax obligation,
valued at their fair market value. Such shares may not be subject to any
repurchase, forfeiture, unfulfilled vesting or other similar requirements.

EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974

         The Plan is not qualified under Section 401(a) of the Code and the
Company believes that the Plan is not subject to the Employee Retirement Income
Security Act of 1974.

                   RESALE OF SHARES BY OFFICERS AND DIRECTORS

         Shares of Common Stock purchased upon exercise of options granted under
the Plan may be resold freely, except that any Participant deemed to be an
"affiliate" of the Company, within the meaning of the Securities Act and the
rules and regulations promulgated thereunder, may not sell securities acquired
under the Plan unless such securities have been registered by the Company under
the Securities Act for resale by such affiliate or an exemption from
registration under the Securities Act is available. Rule 144 under the
Securities Act provides an exemption from registration provided certain
limitations on the manner of sale and the amount of shares sold are observed
(holding period limitations will not apply). An employee who is not an executive
officer, member of the Board of Directors or 10% shareholder of the Company
generally would not be deemed to be an "affiliate" of the Company.

         Any Director or officer acquiring shares under the Plan should consult
with legal counsel prior to reselling shares of Common Stock. Such sale may
implicate securities laws other than Rule 144, including Rule 10b-5 and Section 
16 under the Exchange Act.

                              AMENDED AND RESTATED
                               BAY NETWORKS, INC.

                    1994 OUTSIDE DIRECTORS STOCK OPTION PLAN


         1.       Establishment and Purpose.

                  (a)      Establishment. The Wellfleet Communications, Inc.
1991 Director Stock Option Plan was adopted on May 16, 1991 and was amended on
June 29, 1993 (the "Prior Plan"). In connection with the combination of
Wellfleet Communications, Inc. ("Wellfleet") and SynOptics Communications, Inc.
("SynOptics") pursuant to the Agreement and Plan of Merger dated as of July 4,
1994, as amended, by and among Wellfleet, SynOptics and a wholly owned
subsidiary of Wellfleet (the "Merger Agreement"), Wellfleet changed its name to
Bay Networks, Inc. Wellfleet terminated the Prior Plan and adopted the Bay
Networks, Inc. 1994 Outside Directors Stock Option Plan (the "Plan") which was
approved by the stockholders on October 20, 1994. Amendment of the Plan was
approved by the stockholders on October 19, 1995.

                  (b)      Effective Time and Purpose. The Plan is established
effective as of the Effective Time (as defined in the Merger Agreement) to
create additional incentive for the outside directors of Bay Networks, Inc. and
any successor corporation thereto (collectively referred to as the "Company") to
promote the financial success and progress of the Company and its subsidiaries.

         2.       Administration. The Plan shall be administered by the Board of
Directors of the Company (the "Board") and/or by a duly appointed committee of
the Board having such powers as shall be specified by the Board. Any subsequent
references herein to the Board shall also mean the committee if such committee
has been appointed and, unless the powers of the committee have been
specifically limited, the committee shall have all of the powers of the Board
granted herein, including, without limitation, the power to terminate or amend
the Plan at any time, subject to the terms of the Plan and any applicable
limitations imposed by law. The Board shall have no authority, discretion, or
power to select the non-employee directors of the Company who will receive
options under the Plan, to set the exercise price of the options granted under
the Plan, to determine the number of shares of common stock to be granted under
option or the time at which such options are to be granted, to establish the
duration of option grants, or alter any other terms or conditions specified in
the Plan, except in the sense of administering the Plan subject to the
provisions of the Plan. All questions of interpretation of the Plan or of any
options granted under the Plan (an "Option") shall be determined by the Board,
and such determinations shall be final and binding upon all persons having an
interest in the Plan and/or any Option. Any officer of the Company shall have
the authority to act on behalf of the Company with respect to any matter, right,
obligation, or election which is the responsibility of or which is allocated to
the Company herein, provided the officer has apparent authority with respect to
such matter, right, obligation, or election.

         3.       Eligibility and Type of Option. Options may be granted only to
directors of the Company who are not employees of the Company or any present or
future parent and/or subsidiary corporations of the Company. Options granted to
eligible directors of the Company ("Outside Directors") shall be nonqualified
stock options; that is, options which are not treated as having been granted
under section 422(b) of the Internal Revenue Code of 1986, as amended (the

                                       1
<PAGE>   2
"Code"). For purposes of the Plan, a parent corporation and a subsidiary
corporation shall be as defined in sections 424(e) and 424(f) of the Code.

         4.       Shares Subject to Option. Options shall be options for the
purchase of the authorized but unissued common stock of the Company (the
"Stock"), subject to adjustment as provided in paragraph 8 below. The maximum
number of shares of Stock which may be issued under the Plan shall be five
hundred thousand (500,000) shares. In the event that any outstanding Option for
any reason expires or is terminated or cancelled and/or shares of Stock subject
to repurchase are repurchased by the Company, the shares allocable to the
unexercised portion of such Option, or such repurchased shares, may again be
subjected to an Option. Notwithstanding the foregoing, any such shares shall be
made subject to a new Option only if the grant of such new Option and the
issuance of such shares pursuant to such new Option would not cause the Plan or
any Option granted under the Plan to contravene Rule 16b-3 under the Securities
Exchange Act of 1934, as amended, and as amended from time to time or any
successor rule or regulation ("Rule 16b-3").

         5.       Time for Granting Options. All Options shall be granted, if at
all, within ten (10) years from the Effective Time.

         6.       Terms, Conditions and Form of Options. Options granted
pursuant to the Plan shall be evidenced by written agreements specifying the
number of shares of Stock covered thereby, in substantially the form attached
hereto as Exhibit A for initial grants and in substantially the form attached
hereto as Exhibit B for subsequent grants, and incorporated herein by reference
(the "Option Agreements"), and shall comply with and be subject to the following
terms and conditions:

                  (a) Automatic Grant of Options. Subject to execution by each
Outside Director of the appropriate Option Agreement:

                           (i)      At the Effective Time, each Outside Director
who was on the Board immediately prior to the Effective Time and continues to
serve on the Board at the Effective Time shall be granted an Option to purchase
thirty thousand (30,000) shares of Stock. Each Outside Director who is first
elected or appointed to serve on the Board at or after the Effective Time shall
be granted an Option to purchase thirty-five thousand (35,000) shares of Stock
upon such election or appointment.

                           (ii)     Each Outside Director shall be granted an
additional Option to purchase ten thousand (10,000) shares of Stock upon the
second though seventh Anniversary Dates of the initial option grant to such
Outside Director.

                           (iii)    The Anniversary Date of an Outside Director
who was on the Board at the Effective Time shall be the date which is twelve
(12) months after the Effective Time and successive anniversaries thereof. The
Anniversary Date of an Outside Director who is elected or appointed to the Board
after the Effective Time shall be the date which is twelve (12) months after
such election or appointment and successive anniversaries thereof.

                           (iv)     Notwithstanding the foregoing, any Outside
Director may elect not to receive an Option granted pursuant to this paragraph
6(a) by delivering written notice of such election to the Board (1) in the case
of an initial Option grant, no later than the Effective Time or 


                                       2
<PAGE>   3
the date upon which such Outside Director commences service on the Board, or (2)
in the case of an anniversary Option grant, no later than six (6) months prior
to the applicable Anniversary Date.

                           (v)      Notwithstanding any other provision of the
Plan, no Option shall be granted to any individual who is no longer serving as
an Outside Director of the Company on an Anniversary Date which would otherwise
be a date of grant.

                  (b) Option Price. The option price per share for an Option
shall be the fair market value of the common stock of the Company, as determined
by the closing price of a share of Stock on the National Association of
Securities Dealers Automated Quotations system (the "NASDAQ System") or other
national securities exchange on the date immediately preceding the date of the
granting of the Option. If the date immediately preceding the date of the
granting of the Option does not fall on a day on which the common stock of the
Company is trading on the NASDAQ System or other national securities exchange,
the date on which the option price per share shall be established shall be the
last day on which the common stock of the Company was so traded prior to the
date of the granting of the Option. Notwithstanding the foregoing, an Option may
be granted with an exercise price lower than the minimum exercise price set
forth above if such Option is granted pursuant to an assumption or substitution
for another option in a manner qualifying with the provisions of section 424(a)
of the Code.

                  (c) Exercise Period of Options. Any Option granted hereunder
shall be exercisable for a term of ten (10) years.

                  (d) Vesting. Options granted pursuant to the Plan shall first
become vested on the day (the "Initial Vesting Date") which is one year from the
date on which the Option was granted. The Option shall be vested on and after
the Initial Vesting Date as follows:

                                    provided the Optionee has
                                    continuously served as a
                                    director of the Company
                                    from the date the Option was
                                    granted until the Initial
                                    Vesting Date.

                                    of the Optionee's continuous
                                    service as a director of the
                                    Company from the Initial
                                    Vesting Date.
</TABLE>

                  In the event of a Transfer of Control, as defined in paragraph
9 below, if the Option is assumed or substituted for by the surviving,
continuing, successor or purchaser corporation, the Option shall continue to
vest according to the provisions of this paragraph 6(d), in addition to the
acceleration of vesting described in paragraph 9 below.

                  (e) Payment of Option Price. Payment of the option price for
the number of shares of Stock being purchased pursuant to any Option shall be
made (i) in cash, by check, in cash equivalent, (ii) by the assignment of the
proceeds of a sale of some or all of the shares being acquired upon the exercise
of an Option (including, without limitation, through an exercise complying with
the provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System) or (iii) by the Optionee's recourse
promissory note. No promissory note shall be permitted if an exercise using a
promissory note would be a violation of any law. Any permitted promissory note
shall be due and payable not more than five (5) years after the Option is
exercised, and interest shall be payable at least annually and be at least equal
to the minimum interest rate necessary to avoid imputed interest pursuant to all
applicable sections of the Code. The Board shall have the authority to permit or
require the Optionee to secure any promissory note used to exercise an Option
with the shares of Stock acquired on exercise of the Option and/or with other
collateral acceptable to the Company.

                           (1)      The Company reserves, at any and all times,
the right, in the Company's sole and absolute discretion, to establish, decline
to approve and/or terminate any program and/or procedures for the exercise of
Options by means of an assignment of the proceeds of a sale of some or all of
the shares of Stock to be acquired upon such exercise.

<PAGE>   5
                           (2)      Unless otherwise provided by the Board, in
the event the Company at any time becomes subject to the regulations promulgated
by the Board of Governors of the Federal Reserve System or any other
governmental entity affecting the extension of credit in connection with the
Company's securities, any promissory note shall comply with such applicable
regulations, and the Optionee shall pay the unpaid principal and accrued
interest, if any, to the extent necessary to comply with such applicable
regulations.

         7.       Authority to Vary Terms. The Board shall have the authority
from time to time to vary the terms of the Option Agreements set forth as
Exhibit A and Exhibit B, respectively, either in connection with the grant of an
individual Option or in connection with the authorization of a new standard form
or forms; provided, however, that the terms and conditions of such revised or
amended form or forms of stock option agreement shall be in accordance with the
terms of the Plan. Such authority shall include, but not by way of limitation,
the authority to grant Options which are immediately exercisable subject to the
Company's right to repurchase any unvested shares of stock acquired by the
Optionee on exercise of an Option in the event such Optionee's service as a
director of the Company is terminated for any reason.

         8.       Effect of Change in Stock Subject to Plan. Appropriate
adjustments shall be made in the number and class of shares of Stock subject to
the Plan and to any outstanding Options and in the option price of any
outstanding Options in the event of a stock dividend, stock split, reverse stock
split, combination, reclassification, or like change in the capital structure of
the Company.

         9.       Transfer of Control. A "Transfer of Control" shall be deemed
to have occurred in the event any of the following occurs with respect to the
Company.

                  (a) the sale or exchange by the stockholders of the Company of
all or substantially all of the stock of the Company where the stockholders of
the Company before such sale or exchange do not retain, directly or indirectly,
at least a majority of the beneficial interest in the voting stock of the
Company;

                  (b) a merger in which the stockholders of the Company before
such merger do not retain, directly or indirectly, at least a majority of the
beneficial interest in the voting stock of the Company; or

                  (c) the sale or exchange of all or substantially all of the
Company's assets (other than a sale or transfer to a subsidiary corporation of
the Company).

         In the event of a Transfer of Control, the Vested Percentage calculated
in paragraph 6(d) above shall be increased by 33-1/3% as of 30 days prior to the
Transfer of Control. However, in no event shall the Vested Percentage exceed
100%. The exercise and/or vesting of any Option that was permissible solely by
reason of this paragraph 9 shall be conditioned upon the consummation of the
Transfer of Control. Any Options which are not exercised as of the date of the
Transfer of Control shall terminate effective as of the date of the Transfer of
Control except, however, if the Options are assumed or substituted for by the
surviving, continuing, successor or purchaser corporation, they shall continue
in effect in accordance with their terms.

         10.      Options Non-Transferable. During the lifetime of the Optionee,
the Option shall be exercisable only by the Optionee. No Option shall be
assignable or transferable by the Optionee, except by will or by the laws of
descent and distribution.

         11.      Termination or Amendment of Plan and Options. The Board,
including any duly appointed committee of the Board, may terminate or amend the
Plan and/or any Option at any time; provided, however, that without the approval
of the stockholders of the Company, there shall be (a) no increase in the total
number of shares of Stock covered by the Plan (except by operation of the
provisions of paragraph 8 above) and (b) no expansion in the class of person
eligible to receive Options; and provided further, that the provisions of the
Plan addressing eligibility to participate in the Plan and the amount, price and
timing of grants of Options shall not be amended more than once every six (6)
months, other than to comport to changes in the Code, or the rules thereunder.
In addition to the foregoing, the approval of the Company's stockholders shall
be sought for any amendment to the Plan for which the Board deems stockholder
approval necessary in order to comply with Rule 16b-3. In any event, no
termination or amendment may adversely affect any then outstanding Option, or
any unexercised portion thereof, without the consent of the Optionee.

         12.      Continuation of Prior Plan as to Outstanding Options.
Notwithstanding any other provision to the contrary, the Prior Plan shall remain
in effect in accordance with its terms and apply to Options granted pursuant to
the Prior Plan.

         IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies
that the foregoing Bay Networks, Inc. 1994 Outside Directors Stock Option Plan
was duly adopted by the Board of Directors of the Company on the 17th day of

                                  THE COMPANY

         Bay Networks, Inc., a Delaware corporation (the "Company"), is the
issuer of the shares of Common Stock covered by this Prospectus. Its principal
offices are located at 4401 Great America Parkway, Santa Clara, California and
its telephone number is (408) 988-2400.

           DESCRIPTION OF THE 1994 OUTSIDE DIRECTORS STOCK OPTION PLAN

         On August 17, 1994, the Board of Directors adopted, and on October 20,
1994 the stockholders approved, the 1994 Outside Directors Stock Option Plan
(the "Plan"). On October 19, 1995 the stockholders approved an amendment to the
Plan. The Plan provides for the grant of nonstatutory options not intended to
meet the requirements of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code"). The purpose of the Plan is to create additional incentive
for the outside directors of the Company to promote the financial success and
progress of the Company and its subsidiaries.

         The following is a brief summary of the provisions of the Plan. This
summary is qualified in all respects by reference to the full text of the Plan,
which the Company will provide, without charge, upon written or oral request of
any person to whom this Prospectus is delivered. Each person granted an option
under the Plan should also carefully review his or her option agreement.

SHARES SUBJECT TO THE PLAN

         The original version of the Plan reserved a total of 500,000 shares of
the Company's Common Stock (subject to adjustment for any dividend, stock split,
reverse stock split, combination, reclassification or other relevant changes in
the Company's capitalization) for issuance pursuant to the Plan. A three-for-two
stock split effective on November 24, 1995 resulted in an adjusted reserve of
750,000 Shares. Shares issued under the Plan consist of authorized but unissued
shares or treasury shares. In the event that any outstanding option expires or
is terminated or cancelled or shares subject to repurchase are repurchased by
the Company, the shares allocable to the unexercised portion of such option, or
such repurchased shares, may again be subjected to an option, provided, however,
that the grant of such new option and issuance of shares pursuant to its
exercise would not cause the Plan or any option granted under the Plan to
contravene Rule 16b-3 under the Exchange Act ("Rule 16b-3").

ADMINISTRATION OF THE PLAN

         The Plan is administered by the Board of Directors of the Company (the
"Board") or by a committee appointed by the Board (the "Committee"). Any
subsequent reference to the Board shall also mean the Committee, if one has been
appointed. The directors are elected by the stockholders of the Company in
accordance with the provisions of the Certificate of Incorporation and the
By-Laws of the Company. None of the members of the Board of Directors receives
any additional compensation for services in connection with the administration
of the Plan. Grants of stock options under the Plan and the amount, exercise
price, nature and recipients of those options are automatic and
non-discretionary according to the provisions of the Plan. However, the Board of
Directors is authorized to interpret the provisions of the Plan.


                                       1
<PAGE>   13
TERMS, CONDITIONS AND FORMS OF OPTIONS

         The Plan provides for option grants by the Company to eligible
directors. Each director who is serving on the Board immediately prior to the
Effective Time (as defined in the Agreement and Plan of Merger dated as of July
4, 1994, as amended, by and between Wellfleet Communications, Inc., SynOptics
Communications, Inc. and Spoke Merger Co., Inc.) and continues to serve on the
Board at or after the Effective Time will be granted, at the Effective Time, an
option to purchase 45,000 shares of Common Stock (adjusted for November 1995
stock split). Each director who is first elected or appointed to serve on the
Board at or after the Effective Time will be granted, on the date of his or her
election or appointment, an option to purchase 52,500 shares of Common Stock
(adjusted for November 1995 stock split). The Plan also provides for the grant
of an option to purchase 15,000 shares of Common Stock (adjusted for November
1995 stock split) to each eligible director on the second through seventh
anniversary of his or her initial option grant under the Plan. The option
exercise price per share for each option granted under the Plan is the last
reported sale price per share of the Company's Common Stock on the Nasdaq
National Market on the date immediately preceding the date of grant (or if no
such price is reported on such date, such price as reported on the nearest
preceding date). An option may be granted with an exercise price that is lower
than the price as determined above if such option is granted pursuant to an
assumption of or substitution for another option in a manner qualifying with the
provisions of Section 424(a) of the Code.

         Each option grant shall be evidenced by a written agreement specifying
the number of shares covered by the option. An option granted under the Plan is
not transferable by the optionee otherwise than by will or by the laws of
descent and distribution and may be exercised during the lifetime of the
optionee only by such optionee.

         Each option vests in equal annual installments over a period of three
years beginning one year after the date of grant, provided that the optionee has
continuously served as a director of the Company from the date the option was
granted. No option is exercisable after the expiration of ten years from the
date of the grant.

         Options may be exercised only by written notice to the Company at its
principal office accompanied (i) by payment in cash or cash equivalent or by
check, (ii) by assignment of the proceeds of a sale of some or all of the shares
being acquired by the exercise of the option (subject to the Company's approval)
or (iii) by the optionee's recourse promissory note when authorized by the
Board.

         A director may elect not to receive an option granted under the Plan by
delivering written notice to the Board, in the case of an initial grant, no
later than the date such director would receive such grant, and in the case of
subsequent option grants, six months prior to such grants.

ELIGIBILITY

         Only directors of the Company who are not employees of the Company or
any present or future parent or subsidiary of the Company are eligible to be
granted options under the Plan.

EFFECTIVE DATE, TERMINATION AND AMENDMENT

         The Plan was adopted by the Board of Directors on August 17, 1994 and
approved by the stockholders on October 20, 1994. Pursuant to its terms, the
Plan became effective on October 21, 1994. On October 19, 1995 the stockholders
approved an amendment to the Plan to provide that shares subject to outstanding
and new grants will vest over a period of three years, and to increase the
number of shares each non-employee director is granted on the second through
seventh anniversary date of his or her initial grant to 10,000 shares.

         The Board of Directors may terminate or amend the Plan or any option
granted under the Plan in any respect whatsoever; provided, however, that
without approval of the stockholders of the Company no revision or amendment may
change the number of shares subject to the Plan or expand the class of persons
eligible to receive options. The approval of the Company's stockholders shall be
sought for any amendment to the Plan for which the Board deems stockholder
approval necessary in order to comply with Rule 16b-3. The provisions of the
Plan addressing eligibility and the amount, price and timing of grants may not
be amended more than once in any six-month period other than to comport to
changes in the Code. No termination or amendment of the Plan may adversely
affect any then outstanding option, or any unexercised portion thereof, without
the consent of the optionee.

TRANSFER OF CONTROL

         In the event of a Transfer of Control, as defined below, the vested
portion of any option shall be increased by 33-1/3%, up to a maximum of the
total number of shares represented by the option, as of 30 days prior to the
Transfer of Control. Such vesting and exercise of an option is conditioned upon
the consummation of the Transfer of Control.

         A Transfer of Control shall be deemed to have occurred in a event of
(i) the sale or exchange by the stockholders of the Company of all or
substantially all of the stock of the Company, or a merger, whereby the
stockholders of the Company immediately before such sale or exchange or merger
do not retain at least a majority of the beneficial interest in the voting stock
of the Company or (ii) the sale or exchange of all or substantially all of the
Company's assets (other than a sale or transfer to a subsidiary corporation of
the Company).

         Any options which are not exercised as of the date of the Transfer of
Control shall terminate effective as of such date provided, however, that if the
options are assumed or substituted by the surviving, continuing, successor or
purchaser corporation, they shall continue in effect in accordance with their
terms.

FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary of the federal income tax treatment of
nonstatutory stock options. The tax consequences recognized by an optionee may
vary; therefore, an optionee should consult his or her tax advisor for advice
concerning any specific transaction.

         No taxable income is recognized by the optionee upon the grant of a
nonstatutory option.

         In the case of the consummation of a merger, consolidation, or other
event described in Section 9(b) of the Plan whereby an option granted under the
Plan may be exercised less than six 

                                       3
<PAGE>   15
months after the date of grant, upon exercise less than six months after the
grant, the optionee must either (1) recognize as ordinary income, on the date
six months after the date of grant, the difference between the fair market value
on such date and the exercise price, or (2) pursuant to Section 83(b) of the
Code, elect to have the difference between the exercise price and the fair
market value at the time of exercise recognized as ordinary income at the time
of exercise. Such an election must be made within 30 days of the option
exercise.

         Upon exercise more than six months after the grant, the optionee must
recognize as ordinary income the difference between the exercise price and the
fair market value at the time of exercise.

         The Company will be entitled to a business expense deduction equal to
the amount of ordinary income recognized by the optionee. Any gain or any loss
recognized upon the subsequent disposition of the purchased shares will be a
capital gain or loss, and will be a long-term gain or loss if the shares are
held for more than one year.

         At the time the option is exercised, in whole or in part, or at any
time thereafter as requested by the Company, the Optionee shall make adequate
provision for foreign, federal and state tax withholding obligations of the
Company, if any, which arise in connection with the option including, without
limitation, obligations arising upon (i) the exercise, in whole or in part, of
the option, or (ii) the transfer, in whole or in part, of any shares of stock
acquired on exercise of the option.

EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974

         The Plan is not qualified under Section 401(a) of the Code and the
Company believes that the Plan is not subject to the Employee Retirement Income
Security Act of 1974.

                          RESALE OF SHARES BY DIRECTORS

         Shares of Common Stock purchased upon exercise of options granted under
the Plan may be resold freely, except that any participant deemed to be an
"affiliate" of the Company, within the meaning of the Securities Act and the
rules and regulations promulgated thereunder, may not sell shares acquired upon
exercise of options granted under the Plan unless such shares have been
registered by the Company under the Securities Act for resale by such affiliate
or an exemption from registration under the Securities Act is available. Rule
144 under the Securities Act provides an exemption from registration provided
certain limitations on the manner of sale and the amount of shares sold are
observed (holding period limitations will not apply). All directors of the
Company are deemed to be "affiliates" and, accordingly, any director intending
to sell shares acquired upon exercise of options granted under the Plan should
consult with legal counsel before making any sales. Such sale may implicate
securities laws other than Rule 144, including Rule 10b-5 and Section 16 under
the Exchange Act.

                 INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

         The following documents, which are filed with the Commission, are
