ITEM 1. BUSINESS
 
OVERVIEW
 
     Wall Data Incorporated ("Wall Data" or the "Company") develops, markets and
supports enterprise software products and associated application tools and
provides comprehensive support and services for its products. The Company's
products deliver existing corporate computing systems, including various host,
database, client/server and public information, to users in a browser or
Windows-based environment. Using Wall Data solutions, organizations can extend
their enterprise information to allow their internal users, remote users,
third-party partners and customers to access information and applications over
corporate intranets, extranets, the Internet and Local Area Networks/Wide Area
Networks ("LAN/WAN").
 
     To reach its global customer base, Wall Data delivers products and services
through multiple distribution channels. The Company uses a combination of direct
sales, telesales, resellers, distributors, original equipment manufacturer
("OEM") arrangements and the Internet.
 
     Wall Data was incorporated in 1982 and has a 15-year history of extending
corporate computing systems to users on new platforms and providing outstanding
business solutions to customers worldwide. With the introduction of Microsoft
Corporation ("Microsoft") Windows in 1989, the Company focused its strategy and
resources on the emerging market for Windows-based personal computer
("PC")-to-host connectivity software and launched the RUMBA(R) brand of software
products. To allow customers to extend their enterprise information and
applications to the Internet, the Company has launched its Cyberprise(TM)
strategy and is increasingly focused on emerging markets for Internet-based
enterprise application solutions.
 
RECENT DEVELOPMENTS
 
  NEW CORPORATE DIRECTION
 
     In January 1998, Wall Data announced the Cyberprise strategy to the public.
Cyberprise products and services enable customers to use existing enterprise
information systems in conjunction with Internet-based technologies. By
migrating existing systems, customers can gain a competitive advantage by
delivering Internet-based solutions more rapidly and at a lower cost than if
they created new applications. New products and services involve a significant
amount of risk. See "--Important Factors Regarding Forward-Looking
Statements -- New Markets; Longer Sales Cycle."
 
  PLANNED PRODUCTS AND RELEASES
 
     In connection with the launch of the Cyberprise strategy, Wall Data
announced the rollout of a complete line of Cyberprise products in 1998.
 
     CYBERPRISE(TM) SERVER PRODUCTS
 
     Cyberprise Server products are the foundation of the Cyberprise solution.
The Cyberprise Server software product line is a Web application server
platform. These products allow users to access their existing enterprise
computing applications and information, as well as public information, through
an easy-to-use, channel-based interface. This channel interface can be easily
customized and accessed through a browser. Cyberprise Server
                                        1
<PAGE>   3
 
software products include features such as Web-based administration and
management, centralized system controls and domain security.
 
     CYBERPRISE HOST PRODUCTS
 
     Cyberprise Host software products provide direct, persistent, browser-based
access to mission-critical information and applications on host systems. The
products enable intranet users to interact with real-time information in a
secure, highly scaleable environment and offer the same mission-critical
reliability found in Wall Data's RUMBA client products.
 
     CYBERPRISE TOOL PRODUCTS
 
     Cyberprise Tool products enable internal developers, consultants, value
added resellers ("VARs") and business users to extend the basic capabilities of
Cyberprise products by creating customized solutions. Cyberprise Tool products
allow developers to customize the presentation of information to users, migrate
client/server applications to the Web and build Web applications that connect to
host transaction applications.
 
     CYBERPRISE DATA PRODUCTS
 
     Cyberprise Data software products publish database queries and reports,
database applications, spreadsheets, word processing documents and other data
sources that make data available to anyone with a Web browser. Additionally,
Cyberprise Data products publish solutions developed with Cyberprise Tool
products, enabling end-users to have relevant, browser-based solutions.
 
     CYBERPRISE CHANNEL PRODUCTS
 
     Cyberprise Channel products deliver business-specific corporate and public
content solutions in an organized fashion to employees, partners and customers
through a browser.
 
     CYBERPRISE SERVICES
 
     Cyberprise Services include service and support, consulting services and
specialized programs that facilitate moving mission-critical systems to the
Cyberprise environment.
 
PRODUCTS
 
     The Company's software products provide computer users in business
organizations with easy access to and use of computer applications and data
residing on multiple host mainframes, minicomputers and servers in
enterprise-wide information system networks and public information networks.
Using Wall Data solution platforms, organizations can extend their enterprise
information to allow their internal users, remote users, third-party partners
and customers to access information and applications over corporate LAN/WAN
systems, intranets, extranets and the Internet.
 
     In addition to the products discussed above under "--Planned Products and
Releases," Wall Data's product line currently includes the following products:
 
  HOST CONNECTIVITY SOFTWARE PRODUCTS
 
     The Company's principal product line is the RUMBA family of PC-based host
connectivity software products, which operate in the Microsoft Windows, Windows
95 and Windows NT environments. RUMBA products support the exchange of
information between PC applications and host applications operating on IBM and
IBM-compatible mainframe computers, IBM AS/400 midrange computers, Digital
Equipment Corporation ("Digital") VAX computers, UNIX computers, Hewlett-Packard
Company ("HP") 3000 and 9000 computers and a variety of client-server and
desktop databases. RUMBA products implement PC-to-enterprise connections using a
wide array of network and communication system configurations, including several
types of direct and LAN communication hardware, multiple LAN operating systems
and a broad range of communications servers and gateways. RUMBA software is
designed to be implemented enterprise-
                                        2
<PAGE>   4
 
wide and to leverage customers' existing investments in host computers,
applications, PCs and networking infrastructure, including investments in
corporate intranets and the Internet.
 
     The Company has derived a substantial majority of its net revenues to date
from sales of its RUMBA client software products, which accounted for 81%, 86%
and 88% of net revenues in 1997, 1996 and 1995, respectively. The RUMBA product
line and related enhancements are expected to continue to account for a majority
of the Company's net revenues in 1998. A decline in demand for RUMBA products as
a result of competition, technological changes or otherwise could have a
material adverse effect on the Company's results of operations. See "--Important
Factors Regarding Forward-Looking Statements -- Dependence on a Single Product
Line."
 
     The Company's RUMBA software products fall into two categories: RUMBA
client software products and RUMBA tool products. In 1989, Wall Data introduced
RUMBA for the Mainframe, Windows Version, which allowed PC users to access and
use host information and applications on IBM and IBM-compatible mainframes.
Since then, the Company has introduced new client software products and features
that allow PC users to access and use host applications and data in various
enterprise-wide networks and public information networks. RUMBA tool products
allow advanced users, developers and administrators to create custom
applications to suit user needs.
 
     RUMBA Client Software Products. RUMBA client software products allow
business users running the Microsoft Windows, Windows 95 and Windows NT
operating systems easy access to character-based and client/server applications
and data residing on IBM and IBM-compatible mainframe computers, IBM AS/400
midrange computers, Digital VAX computers, UNIX computers, HP 3000 and 9000
computers and a variety of client-server and desktop databases. The Company's
client software products operate on PCs. These products implement PC-to-host
connections using a wide array of network and communication system
configurations and are designed to be implemented enterprise-wide. The modular
architecture of RUMBA products has allowed the Company to deliver individual
products to specific markets in accordance with the demands of that market.
Generally, these products are licensed on a per-user basis and may be available
pursuant to enterprise-wide or site licenses.
 
     RUMBA OFFICE products offer a suite of solutions for users needing to
access enterprise server or host systems by providing access to a vast range of
character-based and client/server applications on business-critical systems such
as IBM mainframe, IBM AS/400, Digital VAX, UNIX and HP systems. The modular
architecture of RUMBA OFFICE integrates file and print management, database
access, mail and messaging, and Internet features into a single universal
client. In addition, features such as QuickAssist, which eliminates repetitive
keystrokes, and Hotspots and QuickStep, which allow host applications to be
operated by a mouse instead of the keyboard, help to provide customers with
productivity-enhanced business tools.
 
     RUMBA Tool Products. The Company's RUMBA software tools operate on client
PCs and network servers to enable software developers and advanced users to
customize or develop PC applications making use of host information in
conjunction with RUMBA software. By implementing industry-standard architectures
for custom solution development, including Microsoft's ActiveX component
architecture, RUMBA tool products give developers the ability to produce custom
software solutions that meet specific user needs without having to create the
enterprise information access technology themselves.
 
     RUMBA tools deliver a range of capabilities for enhancing the presentation
of enterprise information on PCs and are designed for users and developers of
varying proficiency: (i) advanced Windows application users can use RUMBA
application tools to present enterprise information in the formats of familiar
Windows applications, such as Excel or Lotus 1-2-3 spreadsheets; (ii) advanced
users or Windows developers can use RUMBA application tools to customize or
develop specific Windows applications designed to incorporate enterprise
information; and (iii) more sophisticated developers can use RUMBA application
tools in connection with industry-standard application programming interfaces
and computer-aided software engineering tools to develop sophisticated PC
applications and transaction programs interfacing with host applications. These
products are licensed on a per-unit basis and may be available pursuant to
enterprise-wide or site licenses.
 
                                        3
<PAGE>   5
 
     Other Software Products. The Company also offers ARPEGGIO(R) and SALSA(R)
software products. ARPEGGIO products allow organizations to publish database
information across a variety of platforms. SALSA products allow advanced
computer users to create their own customized client/server applications.
 
SERVICE
 
     Wall Data is committed to providing responsive, high-quality product
support and product upgrades for the Company's software products. These services
are marketed under the ONESTEP(R) brand. This flexible annual program provides
responsive, priority product support at predictable costs, augments customers'
support staff and maximizes user productivity. Customers can select the support
options that best fit the size, structure and service requirements of their
organization. Separate service offerings are available for various Wall Data
products. Individual program options include: priority telephone access to Wall
Data senior support engineers; electronic services on the Web that provide
on-line case entry, privileged access to Wall Data's online information base,
and the ability to download current product updates and fixes; and upgrade
subscription, which keeps the customer's software current with the latest
upgrades and updates.
 
SALES, MARKETING AND DISTRIBUTION
 
     The Company markets its products primarily to multinational and national
business organizations with installed enterprise computer systems. These
organizations vary in size, complexity and purchasing-decision structures. To
address these ranges of sales and marketing opportunities, Wall Data uses a
combination of direct sales, telesales, resellers, distributors and OEM
arrangements.
 
     The direct sales force focuses on large business organizations and markets
to several levels within these organizations, including the executive,
management information systems, department/division and user levels. The Company
also sells its products through indirect channels, primarily consisting of
distributors and national and regional resellers addressing the business market.
The Company supports its resellers and distributors with experienced sales,
marketing, systems engineering and technical support staffs. In addition, the
Company relies on resellers and distributors to market and support its products
in certain markets. There can be no assurance, however, that such resellers and
distributors will be able to market the Company's products effectively or be
qualified to provide timely and cost-effective customer support or service. See
"--Important Factors Regarding Forward-Looking Statements -- Reliance on
Resellers and Distributors."
 
     Wall Data sells its product lines through national distributors such as
Ingram Micro, Inc., Merisel, Inc. and Tech Data Corporation, which may in turn
sell to other resellers, VARs and dealers. Additionally, the Company's resellers
include Corporate Software and Technology, Entex Information Systems, Shared
Medical Systems, Softmart, Inc. and Software Spectrum, Inc. The Company's
agreements with resellers and distributors typically are not exclusive and may
be terminated by either party without cause. Many of the Company's resellers and
distributors carry competing product lines. There can be no assurance that any
resellers or distributors will continue to represent the Company's products or
that additional resellers or distributors will agree, or continue, to represent
the Company's products. The Company's distributors generally are permitted
inventory exchange or rotation rights.
 
     Wall Data also has entered into OEM agreements with certain companies
including IBM pursuant to which these companies market derivatives of RUMBA
products under various names. The OEM agreements generally provide for
nonexclusive licenses of specific versions of RUMBA software and allow the OEMs
to combine the specific version of RUMBA software with their product-specific
software and to distribute and market the derivative of the RUMBA software
product under their own names. The Company generally receives a license fee or
royalty based on the number of copies of products or derivatives of RUMBA
distributed to end users or used internally. The Company's OEM agreement with
IBM expires in 2001. Such agreements may be terminated by either party upon
breach by the other party, and the agreement with IBM is terminable by IBM upon
90 days' notice. The Company intends to pursue OEM agreements with additional
companies. Sales pursuant to OEM agreements accounted for approximately 7% of
the Company's net revenues in 1997.
 
                                        4
<PAGE>   6
 
     The Company's marketing programs are designed to create user awareness and
generate sales opportunities for its direct sales force and telesales, as well
as its resellers, distributors and OEMs. These programs include press releases,
press and industry analyst relations, advertising in trade and business
publications, direct mail advertising, participation in regional conferences,
seminars, trade shows and industry conferences and provision of ongoing customer
communication programs. In addition, the Company provides demonstration disks
and trial versions of the software to promote the products and provide product
information. Additional sales support is provided to resellers through product
literature and promotional programs. The Company also assists the marketing
efforts of certain of its resellers and distributors by providing funds for
promotional and educational purposes.
 
     Approximately 30%, 29% and 28% of the Company's net revenues in 1997, 1996
and 1995, respectively, were attributable to sales made to customers outside
North America. The Company expects that international sales will continue to be
a significant portion of its business. The Company's international sales efforts
are focused primarily on large business organizations that may have computing
resources located throughout the world. The Company has sales and/or marketing
staff located in Argentina, Australia, Brazil, Canada, England, France, Germany,
Ireland, Italy, Japan, Mexico, Singapore, Spain and the United States.
Currently, the Company's sales in Europe are made primarily through local
resellers and distributors. Agreements with local resellers and distributors
generally provide the resellers nonexclusive rights to sell the Company's
products in a specified geographic area. Resellers typically are required to pay
license fees for all products shipped to them and agree to market the products.
Generally, the agreement may be terminated by the Company if the reseller
breaches the agreement or fails to reach agreed-upon sales quotas and, after one
year, may be terminated by either party with three months' notice. See Note 12
of Notes to Consolidated Financial Statements for more information regarding
foreign operations and export sales.
 
     The Company faces certain risks inherent in international business
operations, including fluctuations in foreign currency exchange rates, the
instability of certain overseas economic environments, longer accounts
receivable payment cycles, difficulties in staffing and managing international
operations, unexpected changes in regulatory requirements, tariffs and other
trade barriers, potentially adverse tax consequences, repatriation of earnings
and the burdens of complying with a wide variety of foreign laws. There can be
no assurance that such factors will not have a material adverse effect on the
Company's future international sales and, consequently, on the Company's results
of operations. See "--Important Factors Regarding Forward-Looking
Statements -- International Operations."
 
PRODUCT DEVELOPMENT
 
     The Company intends to enhance and expand its product lines in connection
with evolving customer requirements and industry standards and other
technological changes. The Company believes its future success will depend on
its ability to do so and any failure by the Company to anticipate or respond
adequately to changes in technology and customer preferences, or any significant
delay in product development or introduction, could have a material adverse
effect on the Company's results of operations. The Company employs engineers to
develop new products and product enhancements. Historically, the Company
generally has developed new products internally but, from time to time, has
acquired or licensed technologies from third parties. Although there can be no
guarantee that product development efforts will result in commercially viable
products, Wall Data intends to continue to make substantial investments in
product development. See "-- Important Factors Regarding Forward-Looking
Statements -- New Products; Technological Change; Uncertain Acceptance of the
Company's New Products." Wall Data's product development expenses totaled $19.7
million, $22.9 million and $19.8 million in 1997, 1996 and 1995, respectively.
 
COMPETITION
 
     The enterprise software market is intensely competitive and subject to
rapidly changing technology and evolving standards incorporated into PCs,
networks, host computers and enterprise servers.
 
     The market for the Company's products is also characterized by significant
price competition, and the Company expects it will face increasing pricing
pressures. There can be no assurance that the Company will be able to maintain
its historic prices, and an inability to do so could materially adversely affect
the Company's results of operations.
                                        5
<PAGE>   7
 
     The principal competitive factors affecting the market for the Company's
products include product functionality, ease of use, price, quality, performance
and reliability; quality of customer service and support; product availability;
vendor credibility; and ability to keep pace with technological change. There
can be no assurance that the Company will continue to compete successfully in
the face of increasing competition from new products and enhancements introduced
by existing competitors and new companies entering the market.
 
     The Company competes with providers of PC-to-host connectivity products,
including, without limitation, IBM, Attachmate Corporation and WRQ, Inc. In
addition, the Company competes with providers of software products for TCP/IP
networks such as Novell, Inc. ("Novell"), FTP Software, Inc., NetManage, Inc.
and Hummingbird Communications, Limited. With the introduction of Internet-based
solutions, the Company also may compete with providers of software products for
Internet and corporate intranet information publishing products such as IBM and
Netscape Communications Corp. These products allow PCs to access information
from enterprise servers or host systems using Internet browsers, and may cause
customers to re-evaluate their information and application access strategy in
ways that reduce the need for the Company's client products.
 
     In general, customers and prospective customers of the Company's products
have competitors' connectivity products installed, and the Company competes with
these vendors for customer orders. The Company derives a substantial portion of
its net revenues from sales of its RUMBA products for IBM and IBM-compatible
mainframe computers and IBM AS/400 midrange computers. IBM sells products that
compete with those of the Company and can exercise significant customer
influence and technology control in the IBM PC-to-host connectivity market. The
Company also competes with providers of LAN systems and software products that
can provide PC-to-host connectivity. Microsoft currently incorporates limited
PC-to-host connectivity technology in Windows. The Company expects that
Microsoft will continue to include and expand this technology in its future
products and product enhancements. The introduction by Microsoft of a client
software connectivity product or formation of a significant relationship with a
competitor of the Company could materially adversely affect sales of the
Company's products. Also, the introduction of Internet and corporate intranet
technology by the Company's traditional competitors or by any other company in
the Internet/intranet technology market could reduce the demand for the
Company's products. Many of the Company's competitors have substantially greater
financial, technical, sales and marketing and other resources, as well as
greater name recognition and a larger installed base, than the Company. The
Company believes that competition will increase in the future.
 
PROPRIETARY RIGHTS
 
     The Company regards its software as proprietary and relies on a combination
of patent, trademark and copyright laws, trade secrets, confidentiality
procedures and contractual provisions, including employee and third-party
nondisclosure and proprietary rights agreements, to protect its proprietary
rights. The Company has registered and filed applications to register its
trademarks "WALL DATA", "RUMBA", "ONESTEP", "SALSA" and "ARPEGGIO" and their
associated logos in the United States and other countries and has pending
trademark applications in the United States and other countries for "Cyberprise"
and "The Power of Cyberprise". The laws of some foreign countries may not
protect the Company's proprietary rights to the same extent as do the laws of
the United States.
 
     Despite the Company's efforts to protect its proprietary rights,
unauthorized parties may attempt to copy aspects of the Company's products or to
obtain and use information the Company regards as proprietary. Policing
unauthorized use of the Company's products is difficult, and while the Company
is unable to determine the extent to which piracy of its software products
exists, it expects software piracy to be a persistent problem.
 
     The Company typically distributes its products to users under nonexclusive,
nontransferable licenses, which restrict use of the product solely for the
customer's internal operations. In licensing some of its products, the Company
relies on "shrink wrap" licenses that are not signed by licensees and,
therefore, may be unenforceable. In other circumstances, the Company makes
available enterprise-wide licenses, which permit use and copying of the product
for internal purposes only and typically are for limited terms. In addition, the
 
                                        6
<PAGE>   8
 
Company has entered into certain agreements pursuant to which it has licensed
object code for specific products and, in certain cases, has entered into source
code escrow agreements. Pursuant to these escrow agreements, the Company
deposits the source code for the licensed product and related materials with an
escrow agent or trustee who must maintain the confidentiality of the source code
and may release the source code and materials to the licensee only in the event
of insolvency or dissolution of, or reasonably certain nonperformance by, the
Company. Upon such release, the licensee may use the released source code and
materials only in accordance with the restrictions under the terms of its
license or OEM agreement with the Company.
 
     No material claims have been made against the Company for infringement of
proprietary rights of third parties. There can be no assurance, however, that
third parties will not assert infringement claims against the Company in the
future.
 
     As the number of software products in the industry increases and the
functionality of these products further overlaps, the Company believes that
software programs will become increasingly subject to infringement claims. The
cost of responding to any such assertion may be material, whether or not the
assertion is valid. See "--Important Factors Regarding Forward-Looking
Statements -- Intellectual Property and Proprietary Rights."
 
SEASONALITY
 
     The Company's business is seasonal. A substantial portion of the Company's
annual net revenues and operating income typically occur in the fourth quarter,
and in each of the last five years, the first quarter revenues have been down
sequentially compared with the immediately preceding fourth quarter. In
addition, the third quarter of each year typically is characterized by more
difficult sales cycles, particularly in Europe, as customers tend to procure
more slowly during the summer months.
 
EMPLOYEES
 
     As of December 31, 1997, the Company's headcount totaled 793 persons,
including employees and contractors. The Company believes that its future
success continues to depend, in part, on its ability to continue to attract and
retain skilled technical, marketing and management personnel. Competition for
such personnel in the computer industry is intense. The Company believes its
relations with its employees are good.
 
IMPORTANT FACTORS REGARDING FORWARD-LOOKING STATEMENTS
 
     The following important factors, among others, could cause Wall Data's
actual results to differ materially from those expressed in Wall Data's
forward-looking statements in this Report and presented elsewhere by management
from time to time.
 
     New Products; Technological Change; Uncertain Acceptance of the Company's
New Products. The market for the Company's products is characterized by rapidly
changing technology, evolving industry standards, changes in customer needs and
frequent new product introductions. The Company's future success will depend on
its ability to enhance its current products, to develop new products on a timely
and cost-effective basis that meet changing customer needs and to respond to
emerging industry standards and other technological changes, such as Web-based
technologies. In particular, the Company must be able to modify its products to
maintain compatibility with IBM and IBM-compatible mainframe computers, IBM
AS/400 midrange computers, Digital VAX computers, Novell LAN operating systems,
Microsoft Windows, and industry-standard PCs, hosts and communications
interfaces. In addition, the Company must adapt its current products, and
develop new ones, to address the rapidly evolving Internet and corporate
intranet market. Any failure by the Company to anticipate or respond adequately
to changes in technology and customer preferences or industry standards, or any
significant delays in product development or introduction, would have a material
adverse effect on the Company's results of operations. There can be no assurance
that the Company will be successful in developing new products or enhancing its
existing products on a timely basis, or that such new products or product
enhancements will achieve market acceptance. See "-- Product Development" and
"--Competition."
                                        7

     Software products as complex as those offered by the Company may contain
undetected errors or failures when first introduced or as new versions are
released. There can be no assurance that, despite significant testing by the
Company and by current and potential customers, errors will not be found in new
products after commencement of commercial shipments, resulting in loss of or
delay in market acceptance. Furthermore, from time to time the Company and
others may announce new products, capabilities or technologies that have the
potential to replace or shorten the life cycles of the Company's existing
products. There can be no assurance that announcements of currently planned or
other new products will not cause customers to defer purchasing existing Company
products or cause distributors to return products to the Company. Delays or
difficulties associated with new product introductions or product enhancements
could have a material adverse effect on the Company's results of operations.
 
     New Markets; Longer Sales Cycle. The Company's initial software products
provided client-based software that operated in a LAN/WAN environment. The
Company has now announced products that allow organizations to extend their
enterprise applications and information beyond the LAN/WAN environment to their
corporate intranet, extranets and the Internet. The Company's new Cyberprise
strategy and products are focused on enabling organizations to migrate their
existing enterprise information to Internet-based technologies. As the Company
increases its focus on providing leading Internet-based enterprise solutions for
its customers, the Company's business is expected to be characterized by longer
sales cycles and more complex use of its software. These sales generally include
increased involvement by application developers, integrators or other
consultants and involve a significant commitment of capital by prospective
customers, with attendant delays. The Company has relatively limited experience
with sales of Internet-based server software products or licensing models used
in that environment, and there can be no assurance that the Company will be able
to successfully manage its new product line, and the failure to do so could have
a material adverse effect on the Company's business, operating results and
financial condition.
 
     Variability in Quarterly Performance. The Company's results of operations
historically have varied substantially from quarter to quarter, and the Company
expects that they will continue to do so. The timing and amount of the Company's
quarterly net revenues depend on a number of factors, such as the size and
timing of customer orders or license agreements, the timing of the introduction
and customer acceptance of new products or product enhancements by the Company
or its competitors, changes in computer operating systems introduced by
Microsoft, IBM or other companies, changes in pricing policies by the Company or
its competitors, product returns or rotations, fluctuations in foreign exchange
rates, customers postponing purchases of software products while they find year
2000 fixes, and changes in general economic conditions. Products generally are
shipped as orders are received. Accordingly, the Company historically has
operated with little or no backlog. In addition, the Company's operating
expenses are relatively fixed in the short term, and a significant portion of
the revenues for each quarter typically is received near the end of the quarter.
As a result, variations in timing of revenues can cause significant variations
in quarterly results of operations. The Company does not generally take measures
that are specifically designed to limit fluctuations in the Company's quarterly
results of operations. There can be no assurance that the Company will be
profitable on a quarter-to-quarter basis in the future.
 
     The growth in net revenues and operating income experienced by the Company
in past years is not necessarily indicative of future results. In view of the
significant growth of the Company's operations in past years, the Company
believes that period-to-period comparisons of its financial results are not
necessarily meaningful and should not be relied on as an indication of future
performance.
 
     The Company's business is seasonal. A substantial portion of the Company's
annual net revenues and operating income typically occur in the fourth quarter,
and in each of the last five years, the first quarter revenues have been down
sequentially compared with the immediately preceding fourth quarter. In
addition, the third quarter of each year typically is characterized by more
difficult sales cycles, particularly in Europe, as customers tend to procure
more slowly in the summer months.
 
     Competition. The connectivity market within the computer industry is
intensely competitive and subject to rapidly changing technology and evolving
standards incorporated into PCs, networks, host computers and enterprise
servers. In general, customers and prospective customers of the Company's
products also have
 
                                        8
<PAGE>   10
 
competitors' connectivity products installed, and the Company competes with
these vendors for customer orders. The introduction by Microsoft of a client
software connectivity product or formation of a significant relationship with a
competitor of the Company could adversely affect sales of the Company's
products. Also, the introduction of Internet and corporate intranet technology
by the Company's traditional competitors or by any other company in the
Internet/intranet technology market may reduce the demand for the Company's
products. Many of the Company's competitors have substantially greater
financial, technical, sales and marketing and other resources, as well as
greater name recognition and a larger installed base, than the Company. The
Company believes that competition will increase in the future. The market for
the Company's products is also characterized by significant price competition,
and the Company expects that it will face increasing pricing pressures. There
can be no assurance that the Company will be able to maintain its historic
prices, and an inability to do so could adversely affect the Company's results
of operations. There can be no assurance that the Company will continue to
compete successfully in the face of increasing competition from new products and
enhancements introduced by existing competitors and new companies entering the
market. See "--Competition."
 
     Dependence on a Single Product Line. The Company has derived a substantial
portion of its net revenues to date from sales of its RUMBA client software
connectivity products, and the RUMBA product line and related enhancements are
expected to continue to account for a substantial portion of the Company's net
revenues for the foreseeable future. A decline in demand for RUMBA products as a
result of competition, technological change or otherwise would have a material
adverse effect on the Company's results of operations. See "--Products" and
"--Competition."
 
     Dependence on Host Computers. The Company's products are designed for use
with IBM and IBM-compatible mainframe computers, IBM AS/400 midrange computers
and Digital VAX computers. If business organizations were to reduce their use of
these host computers, the market for the Company's products would be adversely
affected. In addition, because the Company's products operate in conjunction
with IBM and Digital system software, the Company must adapt its products to
technological changes by IBM and Digital. Any failure by the Company to do so in
a timely manner would adversely affect the Company's results of operations. See
"--Products" and "--Competition."
 
     Dependence on Microsoft Windows. Substantially all of the Company's net
revenues are derived from the sales of products designed to achieve host
connectivity within a Microsoft Windows environment and are marketed primarily
to Windows users. As a result, sales of the Company's products could be
materially adversely affected by market developments adverse to Windows. In
addition, the Company's strategy of developing products using the Windows
environment is substantially dependent on its ability to gain access to, and to
develop expertise in, current and future Windows developments by Microsoft in a
timely fashion. See "--Products" and "--Competition."
 
     Dependence on the Internet. As the Company focuses on delivering
Internet-based solutions for its customers' enterprise application needs, sales
of the Company's products will increasingly depend on adequate access to the
Internet. The Internet also may develop more slowly than expected for a variety
of reasons, such as inadequate development of the necessary infrastructure or
complementary products. There can be no assurance that the Internet
infrastructure will continue to be able to support the demands placed on it by
potential growth. If the necessary infrastructure or complementary products are
not developed, or if the Internet develops more slowly than expected, the
Company's business, operating results and financial condition will be materially
adversely affected.
 
     Reliance on Resellers and Distributors. Although the Company intends to
continue to expand its own sales and marketing staff to sell products directly
to its customers, in the future the Company expects to continue to rely on
resellers and distributors for sales of its products. There can be no assurance,
however, that such resellers and distributors will be able to market the
Company's products effectively. The Company's agreements with resellers and
distributors are not exclusive and may be terminated by either party without
cause. Many of the Company's resellers and distributors carry competing product
lines. There can be no assurance that any reseller or distributor will continue
to represent the Company's products. In addition, the Company will be
increasingly dependent on the continued viability and financial stability of
resellers and
 
                                        9
<PAGE>   11
 
distributors, which, in turn, are substantially dependent on the PC industry.
The inability to recruit, or the loss of, important resellers or distributors
could materially adversely affect the Company's results of operations. See
"--Sales, Marketing and Distribution."
 
     The Company also expects to rely increasingly on resellers and distributors
to support its products. There can be no assurance, however, that the Company
will be able to attract resellers and distributors qualified to provide timely
and cost-effective customer support or service. Any deficiencies in the service
or support provided by such entities could have a material adverse effect on the
Company's results of operations. See "--Sales, Marketing and Distribution."
 
     International Operations. The Company expects that international sales will
continue to account for a significant portion of its business. An increase in
the value of the U.S. dollar relative to foreign currencies could make the
Company's products less competitive in those markets in which the Company's
products are sold. The Company does not currently engage in foreign currency
hedging transactions, although it may implement such transactions in the future.
Operating expenses relating to foreign offices also are subject to the effects
of fluctuations of foreign currency exchange rates. The Company faces certain
risks inherent in international business operations, including fluctuations in
foreign currency exchange rates, the instability of certain overseas economic
environments, longer accounts receivable payment cycles, difficulties in
staffing and managing international operations, unexpected changes in regulatory
requirements, tariffs and other trade barriers, potentially adverse tax
consequences, repatriation of earnings and the burdens of complying with a wide
variety of foreign laws. There can be no assurance that such factors will not
have a material adverse effect on the Company's future international sales and,
consequently, on the Company's results of operations.
 
     Risks Related to the Year 2000. The Company has developed plans to address
issues related to the impact on its products and systems of the year 2000.
Products have been modified, financial and operational systems have been
assessed and plans have been developed to address modification requirements. If
the Company or its vendors or distributors are unable to resolve such issues in
a timely manner or if the Company's products are used in conjunction with the
software of other suppliers that have not adequately addressed year 2000 issues,
it could result in a material financial risk. Accordingly, the Company plans to
devote the necessary resources to resolve all significant year 2000 issues in a
timely manner.
 
     Dependence on Key Personnel; Management of Growth. The Company's success
depends to a significant extent on a number of senior management personnel,
including the President and Chief Executive Officer, John R. Wall, and the Chief
Operating Officer, Kevin B. Vitale. The loss of the services of these key
persons would have a material adverse effect on the Company. The Company has no
employment agreement with Mr. Wall or Mr. Vitale. The Company's success also
depends in part on its ability to attract and retain qualified professional,
technical, managerial and marketing personnel. Competition for such personnel in
the software industry is intense. There can be no assurance that the Company
will be successful in attracting and retaining the personnel it requires to
develop new and enhanced products and to conduct its operations successfully.
The ability of the Company to sustain growth will depend in part on the ability
of its officers and key personnel to manage growth successfully through
implementation of appropriate management systems and controls. The Company's
results of operations could be materially adversely affected if the Company were
unable to attract, hire, assimilate, train and manage these personnel, or if
revenues failed to increase at a rate sufficient to absorb the resulting
increase in expenses. See "--Sales, Marketing and Distribution" and
"--Employees."
 
     Intellectual Property and Proprietary Rights. Despite the Company's efforts
to protect its proprietary rights, unauthorized parties may attempt to copy
aspects of the Company's products or to obtain and use information that the
Company regards as proprietary. Policing unauthorized use of the Company's
products is difficult, and while the Company is unable to determine the extent
to which piracy of its software products exists, it expects software piracy to
be a persistent problem. In licensing some of its products, the Company relies
on "shrink wrap" licenses that are not signed by licensees and, therefore, may
be unenforceable. In addition, the laws of some foreign countries may not
protect the Company's proprietary rights to the same extent as do the laws of
the United States. There can be no assurance that these protections will be
adequate or that the Company's competitors will not independently develop
similar technology. There can be no
 
                                       10
<PAGE>   12
 
assurance that third parties will not assert infringement claims against the
Company in the future. As the number of software products in the industry
increases and the functionality of these products further overlaps, the Company
believes that software programs will become increasingly subject to infringement
claims. The cost of responding to any such assertion may be material, whether or
not the assertion is valid. See "--Proprietary Rights."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
RESULTS OF OPERATIONS
 
  Overview
 
     The Company's results of operations have historically varied substantially
from quarter to quarter, and the Company expects that they will continue to do
so. The timing and amount of the Company's quarterly net revenues depend on a
number of factors, such as the size and timing of customer orders or license
agreements, the timing of the introduction and customer acceptance of new
products or product enhancements by the Company or its competitors, changes in
PC operating systems introduced by Microsoft, IBM or other companies, changes in
pricing policies by the Company or its competitors, product returns or
rotations, fluctuations in foreign exchange rates, customers postponing
purchases of software products while they find
 
                                       14
<PAGE>   16
 
year 2000 fixes and changes in general economic conditions. Net revenues will
also depend upon the success of the Company's recently announced Cyberprise
strategy. Products generally are shipped as orders are received and,
accordingly, the Company historically has operated with little or no backlog. In
addition, the Company's operating expenses are relatively fixed in the short
term and a significant portion of the revenues for each quarter typically is
received near the end of the quarter. As a result, variations in timing of
revenues can cause significant variations in quarterly results of operations.
 
     The Company has developed plans to address issues related to the impact on
its products and systems of the year 2000. Products have been modified,
financial and operational systems have been assessed and plans have been
developed to address modification requirements. The financial impact of making
the required changes is not expected to be material to the Company's
consolidated financial position, results of operations or cash flows. However,
if the Company or its vendors or distributors are unable to resolve such issues
in a timely manner or if the Company's products are used in conjunction with the
software of other suppliers that have not adequately addressed year 2000 issues,
it could result in a material financial risk. Accordingly, the Company plans to
devote the necessary resources to resolve all significant year 2000 issues in a
timely manner.
 
     The growth in net revenues and operating income experienced by the Company
during the past five years is not necessarily indicative of future results. In
view of the significant growth of the Company's operations in recent years, the
Company believes that period-to-period comparisons of its financial results are
not necessarily meaningful and should not be relied on as an indication of
future performance.
 
     The Company's business is seasonal, with a substantial percentage of its
annual net revenues and operating income typically occurring in the fourth
quarter of the year. Since 1991, the Company has frequently incurred higher
operating expenses in each sequential quarter primarily due to an increase in
the number of employees. The Company expects that in the first quarter of 1998
lower net revenues, as compared to the fourth quarter of 1997, will result in
significantly lower net income.

</TABLE>
 
     Net revenues increased 1% in 1997. Increases in revenue from ONESTEP
customer support contracts was substantially offset by decreases in revenue from
licenses of RUMBA products. The Company believes that the growth in net revenues
in 1997 was lower than in prior years due to lengthening sales cycles for its
core products as its customers continue to evaluate Internet technology
strategies for future mission-critical systems. Approximately 60% and 25% of net
revenues in 1997 related to products containing 32-bit technology and 16-bit
technology, respectively.
 
     Net revenues increased 26% in 1996 primarily due to increases in revenues
from the Windows version of RUMBA OFFICE, the Company's multi-host product, and
ONESTEP customer support contracts, partially offset by reductions in sales of
certain single host products, principally RUMBA for the Mainframe. In March
1996, the Company released commercial versions of a number of RUMBA software
products, incorporating the ActiveX component architecture designed for the
Windows 95 and Windows NT 32-bit operating systems. Approximately 29% and 61% of
net revenues in 1996 related to products containing 32-bit technology and 16-bit
technology, respectively. In 1995, approximately 89% of net revenues resulted
from 16-bit products. Net revenues from the SALSA product family, which the
Company introduced in March 1996, were not significant.
 
     The Company has derived a substantial majority of its net revenues to date
from licenses of its RUMBA client software products, which accounted for 81%,
86% and 88% of net revenues in 1997, 1996 and 1995, respectively. The RUMBA
product line and related enhancements are expected to account for a majority of
the Company's net revenues for 1998. A decline in demand for RUMBA products as a
result of competition, technological changes or otherwise would have a material
adverse effect on the Company's results of operations. The Company recently
announced its Cyberprise strategy, which is designed to enable companies
 
                                       15
<PAGE>   17
 
to move existing mission-critical systems and public information to the Web and
extend those systems to remote users, vendors and customers. There can be no
assurance that the Cyberprise strategy will be successful. See "--Important
Factors Regarding Forward-Looking Statements -- New Products; Technological
Change; Uncertain Acceptance of the Company's New Products" and "--New Markets;
Longer Sales Cycle."
 
     Net revenues related to sales of the Company's products and services
outside North America represented $42.4 million, or 30% of net revenues, in 1997
compared to $40.0 million, or 29% of net revenues, in 1996 and $30.6 million, or
28% of net revenues, in 1995. The increases in international net revenues in
1997 and 1996 were primarily due to increased acceptance of RUMBA products and
increased sales and marketing activities in Europe, particularly in the United
Kingdom. Most of the Company's international revenues in 1997, 1996 and 1995
were generated through its indirect distribution channels. The Company's
international sales are denominated in U.S. dollars and local currencies.
Operating expenses incurred in local currencies relating to the Company's
offices in Europe, Japan, Australia, Singapore and Latin America are also
subject to the effects of fluctuations of foreign currency exchange rates.
Foreign currency exchange rate changes did not have a significant effect on net
revenues in 1997, 1996 and 1995, but exchange rate fluctuations could have an
adverse effect on future net revenues. The Company has experienced limited
difficulties in hiring, training and retaining management-level staff abroad and
in selecting international resellers with technological and sales expertise to
distribute the Company's products. Additional risks inherent in the Company's
international business activities, which have not materially affected the
Company's business to date, generally include unexpected changes in regulatory
requirements, tariffs and other trade barriers, longer accounts receivable
payment cycles, difficulties in managing international operations, potentially
adverse tax consequences, repatriation of earnings and the burdens of complying
with a wide variety of foreign laws.
 
     The Financial Accounting Standards Board recently approved the new American
Institute of Certified Public Accountants Statement of Position ("SOP") No.
97-2, "Software Revenue Recognition." SOP No. 97-2 will be effective for the
Company beginning in the first quarter of 1998. The Company is currently
assessing the impact, if any, of SOP No. 97-2 on its revenue recognition policy.
 
  GROSS MARGIN AND COST OF REVENUE

</TABLE>
 
     Cost of revenues consists of software publishing costs, which include
labor, product media, packaging and documentation, publishing, engineering,
technical support and product quality assurance costs, royalties and licensing
costs, amortization of product localization costs and provisions for obsolete
inventory, doubtful accounts, and reseller rebates. Gross margin, as a
percentage of net revenues, increased in 1997 from 1996 primarily due to lower
software publishing costs and lower royalties and licensing costs, partially
offset by an increase in the amortization of localization costs. Software
publishing costs decreased in 1997 due to the conversion of all product media
from diskettes to compact discs and the adoption of simplified, uniform product
packaging. Royalties and licensing costs decreased in 1997 due to lower RUMBA
software license revenues and lower costs for third-party technology. The
amortization of localization costs increased primarily due to third-party
localization costs incurred in 1996 relating to the major product launches for
certain RUMBA products. The Company amortizes third-party localization costs
over a 24-month period. Gross margin, as a percentage of net revenues, in 1996
approximated the percentage in 1995. Expenses for royalties and amortization of
prepaid licenses may increase in the future if the Company introduces more
products incorporating software licensed from third parties, and amortization of
product localization costs will increase as the Company introduces new products
in international markets.

</TABLE>
 
     All internal software development expenses are expensed as incurred.
Product development expenses are primarily associated with the enhancement of
existing products and the development of new software products, such as ARPEGGIO
LIVE! and RUMBA OBJECTX which were developed and released in 1997 and RUMBA
95/NT, SALSA and ARPEGGIO which were developed in 1995 and 1996 and released in
the first half of 1996. Product development expenses decreased in 1997 due to
lower average headcount, arising from the completion of initial versions of
RUMBA 95/NT and SALSA products in 1996. The reduction also reflects the benefits
obtained from the object-based architecture that was developed during 1996 and
1995. Product development expenses increased in 1996 due to increases in labor
costs (due in part to a small increase in average staffing levels) support costs
for third-party technology, and depreciation. Product development expenses as a
percentage of net revenues decreased in 1997 compared to 1996 due to the
completion of the two major development projects, RUMBA 95/NT and SALSA in early
1996; the percentage decreased in 1996 compared to 1995 due to the completion of
these development projects, together with the higher revenue growth rate in
1996.

</TABLE>
 
     During 1995 through 1997 the Company generally expanded its sales and
marketing operations by increasing staffing levels coupled with increases in the
amount and breadth of its cooperative advertising programs with resellers and
distributors, other marketing programs and trade show activity. The number of
sales offices maintained by the Company totaled 49, 57 and 54 at the end of
1997, 1996 and 1995, respectively, including, at the end of 1997, six offices in
Europe, two offices in Canada, three offices in Latin America and one office
each in Australia, Japan, Mexico and Singapore. The increase in expenses in 1996
was also a result of higher incentive compensation resulting from increased net
revenues and product launch expenses relating to the introduction of the RUMBA
95/NT, SALSA and ARPEGGIO product families. Sales and marketing expenses as a
percentage of net revenues increased in 1997 compared to 1996 primarily due to
the lower revenue growth rate in 1997; the percentage decreased in 1996 compared
to 1995 primarily due to the higher revenue growth rate in 1996.

     General and administrative expenses include general administrative, finance
and accounting, and legal expenses, costs for the management information systems
and human resources departments, and the amortization of goodwill relating to
certain acquisitions. The increases in general and administrative expenses in
1997 and 1996 resulted primarily from increased staffing and associated expenses
necessary to manage and support the Company's growth and, in 1996, also from
higher legal fees as a result of the shareholders' class action lawsuit. (See
Notes 6 and 11 of Notes to Consolidated Financial Statements.) The Company
intends to continue to maintain its general and administrative expenses as
necessary to support its operations. The amortization of goodwill will increase
in 1998 as a result of the Company's acquisition of Software Development Tools,
Inc. in November 1997 and of First Service Computer Dienstleistungs-GmbH ("First
Service") in March 1998. (See Note 14 of Notes to Consolidated Financial
Statements.)

     During 1997, the Company recorded nonrecurring charges totaling $11.5
million ($7.3 million, or $0.74 per share on a diluted share basis, after tax).
In June 1997, the Company agreed to settle the shareholders' class action
lawsuit for $9.1 million, including related legal fees. (See Notes 6 and 11 of
Notes to Consolidated Financial Statements.) The Company also recorded
nonrecurring charges in 1997 of $1.0 million for the restructuring of the SALSA
business unit, $0.6 million for retirement payments to the Company's former
Chairman, President and CEO, and $0.7 million for the write-off of in-process
research and development resulting from the acquisition of Software Development
Tools, Inc. (See Note 6 of Notes to Consolidated Financial Statements.) During
1996, the Company determined to streamline its business operations and recorded
nonrecurring charges totaling $3.1 million ($2.0 million, or $0.20 per share on
a diluted basis, after income taxes) primarily relating to the write-off of
technology investments and prepaid royalties no longer relevant to the Company's
ongoing product offerings and programs. In 1995, the Company recorded
nonrecurring charges totaling $6.8 million ($4.2 million, or $0.42 per share on
a diluted basis, after income taxes) primarily for the write-off of in-process
research and development resulting from the acquisition of Concentric Data
Systems, Inc. in April 1995 and the write-off of the remaining goodwill from
another acquisition. (See Note 6 of Notes to Consolidated Financial Statements.)

     Interest income increased in 1997 compared to 1996 due to higher investment
balances; interest income decreased in 1996 compared to 1995 due to lower
average interest rates. Other income, net of other expenses, includes interest
expense, foreign currency transaction gains and losses and miscellaneous income
and expenses. Foreign currency transactions resulted in net exchange losses of
$0.8 million in 1997, $0.6 million in 1996 and $0.5 million in 1995. To date,
the Company has not engaged in currency hedging transactions against sales
denominated in currencies other than U.S. dollars, although the Company may do
so in the future. In April 1995, the Company sold its equity investment in SPRY,
Inc. for a gain of $14.0 million ($8.7 million, or $0.87 per share on a diluted
basis, after income taxes). (See Note 6 of Notes to Consolidated Financial

     The provision for income taxes includes U.S. federal, state and
international taxes currently payable and deferred taxes arising from temporary
differences in determining income for financial statement and tax purposes. The
decrease in the Company's effective tax rate in 1997 as compared to 1996
resulted primarily
 
                                       18
<PAGE>   20
 
from Foreign Sales Corporation tax benefits and from operating losses incurred
in higher tax rate jurisdictions combined with significant operating profits
earned in jurisdictions with lower tax rates. The increase in the Company's
effective tax rate in 1996 was due to higher profits in certain international
subsidiaries, which are subject to higher tax rates coupled with certain
nondeductible expenses. The Company anticipates that the effective tax rate in
1998 will increase significantly from 1997 and be somewhat lower than in 1996.

     The Company's cash and cash equivalents totaled $70.8 million, or 52% of
total assets, at December 31, 1997, compared to $62.5 million, or 49% of total
assets, at December 31, 1996.
 
     The Company's expenditures for property and equipment for the years ended
December 31, 1997, 1996 and 1995 totaled $3.9 million, $5.1 million and $7.1
million, respectively. The decrease in expenditures in 1997 compared to 1996 and
in 1996 compared to 1995 primarily resulted from reduced growth in average
staffing levels. Although the Company does not currently have any specific
commitments with regard to capital expenditures, it expects to continue to
acquire new capital equipment and make other capital expenditures. Purchases of
prepaid software technology totaled $2.4 million, $1.3 million and $3.2 million
in 1997, 1996 and 1995, respectively. Capitalized third-party localization costs
totaled $3.0 million in both 1997 and 1996; such costs were not material in
1995. The decrease in capitalized localization costs in 1997 as compared to 1996
and the increase in such costs in 1996 as compared to 1995 resulted from the
significant increase in the volume of new product introductions in 1996 compared
to 1997 and 1995 and the expansion of sales operations into new international
markets.
 
     In April 1995, the Board of Directors authorized a stock repurchase program
of up to $10.0 million. Through December 31, 1995, the Company had repurchased
488,200 shares with a total cost of $8.5 million. No shares were repurchased in
1997 or 1996.
 
     In October 1997, the Company acquired a 15% interest in Suntek Information
System Co. Ltd. for approximately $0.9 million. In November 1997, the Company
acquired Software Development Tools, Inc. for $2.0 million. Also in November
1997, the Company acquired a 10% equity interest in DataChannel, Inc. for
approximately $1.7 million. In April 1995, the Company acquired Concentric Data
Systems, Inc. for approximately $7.8 million. See Note 6 of Notes to
Consolidated Financial Statements. The Company will consider, from time to time,
joint ventures, additional acquisitions or investments in other businesses or
third-party technology. The Company believes that existing cash and cash
equivalents, together with funds from operations, will provide the Company with
sufficient funds to finance its operations through 1998.
 
     On March 12, 1998, the Company acquired all the outstanding capital stock
of First Service of Hattingen, Germany and related entities. First Service
distributes and supports a range of connectivity software solutions to major
corporations throughout Germany and has been selling and supporting Wall Data's
products and technologies for more than seven years. The total purchase price
approximates $11.0 million, including deferred payments of approximately $2.0
million that are substantially payable in one year, contingent on the
satisfaction of certain guarantees and warranties. The acquisition will be
accounted for under the purchase method of accounting. See Note 14 of Notes to
Consolidated Financial Statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
 1. SIGNIFICANT ACCOUNTING POLICIES
 
  Business
 
     Wall Data Incorporated ("Wall Data" or the "Company") develops and markets
enterprise software products and associated application tools and provides
comprehensive support and services for its products. The Company's products
deliver existing corporate computing systems, including various host, database,
client/server and public information, to users in a browser or Windows-based
environment. Using Wall Data solutions, organizations can extend their
enterprise information to allow their internal users, remote users, third party
partners and customers to access information and applications over corporate
intranets, extranets, the Internet, Local Area Networks and Wide Area Networks.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. All significant intercompany transactions and
balances are eliminated in consolidation.
 
  Foreign Currency Translation
 
     Assets and liabilities denominated in foreign currencies are translated to
U.S. dollars at the exchange rate on the balance sheet date. Revenues, costs and
expenses are translated at the average rates of exchange prevailing during the
year. Translation adjustments resulting from this process are shown separately
in shareholders' equity.
 
  Revenue Recognition
 
     Revenue from sales of software and hardware products to end-users,
distributors and dealers is recognized when the products are shipped. The
Company's agreements with certain distributors and resellers permit them to
exchange products under certain circumstances and permit returns from certain
resellers subject to specific limitations; an accrual is recognized for
estimated sales returns and exchanges. Revenue from software products licensed
to original equipment manufacturers is recognized as earned. Revenue from
service fees is deferred and recognized on a straight-line basis over the term
of the related agreements. The Company's revenue recognition policies conform to
Statement of Position 91-1, "Software Revenue Recognition," promulgated by the
American Institute of Certified Public Accountants.
 
     The Financial Accounting Standards Board recently approved the new American
Institute of Certified Public Accountants Statement of Position ("SOP") No.
97-2, "Software Revenue Recognition." SOP No. 97-2 will be effective for the
Company beginning in 1998. The Company is currently assessing the impact, if
any, of SOP No. 97-2 on its revenue recognition policy.
 
  Income Taxes
 
     The provision for income taxes includes U.S. federal, state and
international taxes currently payable and deferred taxes arising from temporary
differences between income tax and financial reporting.
 
  Cash and Cash Equivalents
 
     For purposes of the consolidated financial statements, the Company
considers all highly liquid instruments purchased with a maturity of three
months or less at the date of purchase to be cash equivalents. Cost approximates
market value for all cash and cash equivalents. All cash equivalents are
classified as available-for-sale.

                             WALL DATA INCORPORATED
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1997
 
  Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out method) or
market.
 
  Fixed Assets
 
     Fixed assets are stated at cost. Depreciation is computed by the
straight-line method over estimated useful lives ranging from two to ten years
for financial reporting purposes and by different methods approved for income
tax purposes.
 
  Long-term Investments
 
     Long-term investments, consisting of equity investments, are recorded at
cost due to the lack of significant influence.
 
  Prepaid Software Technology Fees
 
     Prepaid software technology license fees are amortized to cost of revenue
using the shorter of the straight-line method over periods not to exceed 24
months or fees based on actual product shipments.
 
  Product Development Costs
 
     A Financial Accounting Standards Board statement requires the
capitalization of certain internal software development costs. Such costs are
not material. Internal product development costs are expensed as incurred.
External costs incurred to localize software products into local market
languages are capitalized and amortized to cost of revenue using the
straight-line method over periods not to exceed 24 months.
 
  Stock Based Compensation
 
     During 1996, the Company adopted the disclosure provisions under Statement
of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation." SFAS No. 123 encourages, but does not require companies to record
compensation expense for stock-based employee compensation based on a prescribed
method for determining fair value. The Company has elected to continue to
account for stock option grants to employees in accordance with APB Opinion No.
25, "Accounting for Stock Issued to Employees," and, accordingly, recognizes
compensation expense for stock options only when the exercise price is less than
the quoted market price at the date of grant.
 
  Advertising Costs
 
     All advertising costs are expensed as incurred. Total advertising expenses
approximated $5.7 million, $6.9 million and $4.5 million in 1997, 1996 and 1995,
respectively.
 
  Earnings per Share
 
     During 1997, the Company adopted SFAS No. 128, "Earnings Per Share." SFAS
No. 128 requires presentation of basic earnings per share and diluted earnings
per share. Basic earnings per share excludes dilution and is based on the
weighted average number of shares of common stock outstanding during the period.
Diluted earnings per share includes the effect of dilutive common equivalent
shares from stock options, using the treasury stock method. The adoption of this
new accounting standard did not have a material effect on the reported earnings
per share of the Company. Prior year earnings per share have been adjusted to
conform to the new accounting standard. The amount of the adjustments was not
material.

  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Accordingly, actual results may differ from
those estimates.
 
  Reclassifications
 
     Certain reclassifications have been made to prior year financial statements
to conform to the current year presentation.
 
 2. MARKETABLE SECURITIES
 
     Marketable securities consist primarily of investment-grade commercial
paper and are classified as available-for-sale. Marketable debt securities with
maturity dates less than three months at December 31, 1997 and 1996 total $45
million and $48 million, respectively, at cost, and are included in cash and
cash equivalents. The estimated fair value of the commercial paper approximates
cost. Marketable equity securities, which are not material, are included in
other assets.

of accumulated amortization of $0.7 million in 1997 and $0.4 million in 1996.
 
     Other assets and long-term investments are regularly reviewed for possible
impairment and are written off if, in the opinion of management, their value has
been impaired.

     Rental expenses under operating leases amounted to approximately $5.2
million, $5.4 million and $4.2 million in 1997, 1996 and 1995, respectively.
 
 6. INVESTMENTS, DISPOSITIONS AND OTHER NON-RECURRING ITEMS
 
     In October 1997, the Company acquired a 15% equity interest in Suntek
Information System Co. Ltd. ("Suntek") for approximately $0.9 million. Suntek
distributes and supports software products in Korea. Management believes that
the investment has not been impaired since the acquisition date.
 
     In November 1997, the Company acquired all the outstanding shares of SDTI
for $2.0 million. An additional $1.0 million is payable contingent on the future
earnings performance of SDTI. SDTI was a privately held developer of Windows
development tools designed to provide a graphical interface to host applications
and to migrate IBM AS/400 and mainframe applications to client/server
environments. The acquisition has been accounted for under the purchase method
of accounting. As a result of this transaction, the Company recorded
non-recurring charges of approximately $741,000 ($667,000, or $0.07 per share on
a diluted basis, after income taxes) for the write-off of in-process research
and development. Approximately $1.3 million of the purchase price was allocated
to developed technology, goodwill and other intangible assets. The intangible
assets are being amortized on a straight-line basis over periods ranging from
four to ten years. Pro forma information relating to the acquisition of SDTI has
not been presented due to immateriality.
 
     In November 1997, the Company and DataChannel, Inc. ("DataChannel") entered
into an agreement under which DataChannel licensed its ChannelManager technology
to the Company. DataChannel is a software development company that creates tools
that streamline the presentation and management of information over corporate
intranets. Pursuant to the licensing agreement, the Company recorded guaranteed
royalties to DataChannel of $1.0 million. The Company is required to pay an
additional $4.0 million for minimum royalties in 1998. In addition, the Company
acquired a 10% equity interest in DataChannel for approximately $1.7 million.
 
     During the second quarter of 1997, the Company recorded several
non-recurring charges totaling $10.7 million ($6.7 million, or $0.67 per share
on a diluted basis, after income taxes). Approximately $9.1 million represents a
charge for the settlement of the shareholders' class action lawsuit. The Company
also recorded restructuring charges of approximately $1.0 million for the
write-off of inventory, technology investments and severance payments relating
to the SALSA business line. The remaining charges represent retirement payments
to the Company's former Chairman and Chief Executive Officer. In July 1997, the
Board of Directors also voted to accelerate the vesting of certain stock options
to the former Chairman. The related compensation expense, which was not
material, was recorded as an expense in the third quarter.

                               DECEMBER 31, 1997
 
     During the fourth quarter of 1996, the Company recorded non-recurring
charges totaling $3.1 million ($2.0 million, or $0.20 per share on a diluted
basis, after income taxes) resulting from decisions to streamline operations and
improve operating efficiencies. The charges primarily related to the write-off
of technology investments and prepaid royalties no longer relevant to the
Company's ongoing product offerings and programs.
 
     In April 1995, the Company acquired all the outstanding shares of
Concentric, a privately held developer of Windows- and DOS-based data access and
reporting tools, for $7.8 million cash. The acquisition has been accounted for
under the purchase method of accounting. As a result of this transaction, the
Company recorded non-recurring charges of approximately $5.5 million ($3.4
million, or $0.34 per share on a diluted basis, after income taxes), for the
write-off of in-process research and development and the write-off of existing
Wall Data prepaid licenses for technology, which was supplanted by the
Concentric technology. Approximately $1.8 million of the purchase price was
allocated to goodwill, which is being amortized over five years. Non-recurring
charges in 1995 also included a $1.0 million write-off of the remaining
unamortized goodwill from a prior acquisition.
 
     In September 1994, the Company acquired a minority equity interest in SPRY,
Inc. ("SPRY"), a developer of Internet access software, for $6.0 million. The
investment was accounted for under the equity method of accounting. In April
1995, the Company sold its equity interest in SPRY for $20.0 million in cash and
recorded a gain of $14.0 million ($8.7 million, or $0.87 per share on a diluted
basis, after income taxes), which is included in other income.

     The Company received compensation deductions in 1997, 1996 and 1995 for
income tax purposes of $0.8 million, $1.0 million and $3.0 million,
respectively, resulting from the exercise of nonqualified stock options and from
disqualifying dispositions of Common Stock received through exercise of
incentive stock options. As required by generally accepted accounting
principles, the resulting tax benefits of $0.3 million, $0.4 million and $1.2
million, respectively, are reported as additions to shareholders' equity rather
than as a reduction of income tax expense.
 
     Deferred income tax assets consist of the following:

     The Company has recorded a valuation allowance to reflect the estimated
amount of deferred tax assets that may not be realized due to the expiration of
net operating losses of certain international subsidiaries. The increase in the
valuation allowance in 1997 results from additional net operating losses of
these subsidiaries. As of December 31, 1997, the Company's international
subsidiaries have unused net operating loss carryforwards, for income tax
purposes, of $4.5 million, which expire primarily in 2002.
 
     Income taxes paid in 1997 and 1995 totaled $0.7 million and $8.2 million,
respectively. In 1996, the Company received net refunds of $0.5 million.

 8. SHAREHOLDERS' EQUITY
 
     In April 1995, the Board of Directors authorized the repurchase of the
Company's Common Stock up to an aggregate purchase price of $10.0 million. As of
December 31, 1995, the Company had repurchased 488,200 shares of Common Stock
for approximately $8.5 million. The Company did not repurchase any shares in
1997 or 1996.
 
     In July 1995, the Board of Directors adopted a shareholder rights
agreement, designed to protect shareholders from coercive takeover tactics, and
declared a dividend of one preferred share purchase right for each outstanding
share of the Company's Common Stock to stockholders of record as of July 31,
1995. The rights entitle the holder (a) to purchase one one-hundredth of a share
of Series A Junior Participating Preferred Stock, no par value per share, of the
Company at a price of $110, subject to adjustment to prevent dilution, upon the
occurrence of triggering events, or (b), in certain circumstances, to purchase
Wall Data Common Stock (or stock of the acquiring entity, as the case may be) at
a 50% discount from its then current market value. Such events would include the
acquisition of Wall Data shares through open market purchases or a tender offer
that, in the aggregate, equals or exceeds 20% of outstanding shares. At the
option of the Board of Directors, the rights may be exchanged for one share of
Wall Data Common Stock for each right. Such rights do not extend to any holder
whose action triggered the rights. The rights expire in August 2005 and may be
redeemed prior to that time at the option of the Board of Directors for nominal
consideration. Until a triggering event occurs, the rights will not trade
separately from the related Wall Data Common Stock.
 
     The Company has several stock-based compensation plans that are described
below. The Company has elected to continue to apply APB Opinion No. 25 in
accounting for its plans and, accordingly, recognizes compensation expense for
employee stock options only when the exercise price is less than the quoted
market price at the date of grant; stock compensation expense was not material
in 1997, 1996 and 1995. Had stock-based compensation been determined based on
the prescribed method for estimating fair value under SFAS No. 123, the
Company's pro forma net income and earnings per share in 1997, 1996 and 1995
would have been $0.2 million, or $0.02 per share on a diluted basis, $2.7
million, or $0.28 per share on a diluted basis, and $6.6 million, or $0.65 per
share on a diluted basis, respectively. The pro forma effects on net income for
1997, 1996 and 1995 are not indicative of the pro forma effects in future years
because SFAS No. 123 does not apply to grants prior to 1995 and additional
grants in future years are anticipated. The pro forma amounts have been
determined using the Black-Scholes option pricing model with the following
weighted average assumptions for 1997, 1996 and 1995, respectively: risk-free
interest rates of 5.9%, 6.5% and 6.3%; volatility factors of 79%, 74% and 77%;
expected life of five years and a zero dividend yield for each year.
 
     The Company has stock option plans that provide for nonqualified and
incentive stock options for officers, employees and consultants. A committee of
the Board of Directors determines the terms and conditions of options granted
under the plans, including the exercise price; however, the exercise price for
incentive stock options shall not be less than the fair market value at the date
of grant. Options granted under the plans generally become exercisable,
cumulatively, at a rate of 25% per year from the date of grant, and expire 10
years from the date of grant. The Company also has a stock option plan for
non-employee directors providing for grants of nonqualified options at an
exercise price that is not less than the fair market value at the date of grant.
 
     In July 1995 and January 1996, the Compensation Committee of the Board of
Directors authorized the exchange of new options for certain previously granted
stock options. Approximately 818,000 shares, ranging in price from $17.00 to
$54.25 per share, were exchanged for new options with an exercise price ranging
from $15.32 to $18.75 per share.

</TABLE>
 
     Certain options to purchase shares of Common Stock were not included in the
computation of diluted earnings per share because the options' exercise price
was greater than the average market price of the common shares. The total shares
that were thus excluded approximated 1,650,000, 1,513,000 and 1,089,000 in 1997,
1996 and 1995, respectively.
 
10. EMPLOYEE BENEFITS
 
     The Company has a Retirement Savings Plan to provide for voluntary salary
deferral contributions on a pretax basis in accordance with Section 401(k) of
the Internal Revenue Code of 1986, as amended. To date, the Company has made no
contributions to the plan.
 
11. LITIGATION
 
     In July 1997, the Company agreed to settle a shareholders' class action
lawsuit for $11.25 million, of which $3.0 million was paid by the Company's
insurance carrier. Included in non-recurring expenses in the second quarter of
1997 is a charge of $9.1 million for the Company's share of the settlement plus
related fees and expenses. The Company paid its share of the settlement in July
1997. Wall Data denied the allegations of the plaintiffs' claims, but agreed to
the settlement to avoid any further expense and the distraction of continued
legal proceedings.
 
12. BUSINESS SEGMENT AND CONCENTRATION OF CREDIT RISK
 
     The Company operates in one business segment: software products and related
services for users of personal computers. Net revenue from ONESTEP service
programs totaled 15.6% of total net revenues in 1997 and 10.3% of net revenues
in 1996; net revenues from services did not exceed 10% of the total in prior
years. The Company distributes its products through a combination of direct
sales, telesales, resellers, distributors, original equipment manufacturer
arrangements and the Internet. The Company performs ongoing credit evaluations
of its customers' financial condition and generally requires no collateral.

                               DECEMBER 31, 1997
 
     Sales to one unaffiliated customer, an OEM customer, accounted for 10% of
net revenues in 1995. Sales to any one customer did not exceed 10% of net
revenues in 1997 or 1996.
 
     Information regarding the Company's operations in different geographic
areas in 1997, 1996 and 1995 is set forth below. Amounts presented for North
America include revenues from customers in North America and certain
international revenues, primarily Japan and Latin America; such international
revenues equaled 4%, 4% and 5% of consolidated net revenues in 1997, 1996 and
1995, respectively. Total international revenues equaled 30%, 29% and 28% of
consolidated net revenues in 1997, 1996 and 1995, respectively. Foreign currency
exchange transactions, which are included in other income (expense), resulted in
net exchange losses of $0.8 million, $0.6 million and $0.5 million in 1997, 1996
and 1995, respectively. The Company has not engaged in currency hedging
transactions against sales denominated in foreign currencies; however, it may do
so in the future.

     Intercompany sales are at prices intended to provide a profit for the
selling entity after coverage of product development, marketing, support and
general and administrative expenses. The identifiable assets by geographic area

13. COMMITMENTS
 
     In May 1997, the Company entered into an agreement with a third party to
provide the Company with information technology services for a ten-year period.
The Company has options to terminate the agreement on the fourth, sixth and
eighth anniversaries of the effective date of the agreement. The minimum
commitment for 1998 is approximately $3.4 million. Annual commitments will
increase each year, thereafter, based on the growth of the Company and
inflation.

14. SUBSEQUENT EVENT
 
     On March 12, 1998, the Company acquired all the outstanding capital stock
of First Service Computer Dienstleistungs-GmbH ("First Service") of Hattingen,
Germany and related entities. First Service distributes and supports a range of
connectivity software solutions to major corporations throughout Germany and has
been selling and supporting Wall Data's products and technologies for more than
seven years. The total purchase price approximates $11.0 million, including
deferred payments of approximately $2.0 million that are substantially payable
in one year, contingent on the satisfaction of certain guarantees and
warranties. The acquisition will be accounted for under the purchase method of
accounting.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
Wall Data Incorporated
 
     We have audited the accompanying consolidated balance sheets of Wall Data
Incorporated as of December 31, 1997 and 1996, and the related consolidated
statements of income, shareholders' equity and cash flows for each of the three
years in the period ended December 31, 1997. Our audits also included the
financial statement schedules listed in the Index at Item 14(a). These financial
statements and schedules are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
schedules based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Wall Data Incorporated at December 31, 1997 and 1996, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted accounting
principles. Also, in our opinion, the related financial statement schedules,
when considered in relation to the basic financial statement taken as a whole,
present fairly in all material respects the information set forth therein.

                             WALL DATA INCORPORATED



        Pursuant to RCW 23B.10.070, the following constitute Restated Articles
of Incorporation of the undersigned, a Washington corporation. These Restated
Articles of Incorporation correctly set forth without change the corresponding
provisions of the Articles of Incorporation as heretofore amended and supersede
the original Articles of Incorporation and all amendments thereto.

                                 ARTICLE 1. NAME

        The name of this corporation is Wall Data Incorporated.

                               ARTICLE 2. DURATION

        This corporation is organized to engage in any business, trade or
activity which may lawfully be conducted by a corporation organized under the
Washington Business Corporation Act.

        This corporation shall have the authority to engage in any and all such
activities as are incidental or conducive to the attainment of the foregoing
purpose or purposes of this corporation and to exercise any and all powers
authorized or permitted under any laws that may be now or hereafter applicable
or available to this corporation.

        4.2    ISSUANCE OF PREFERRED STOCK IN SERIES

        The Preferred Stock may be issued from time to time in one or more
series in any manner permitted by law and the provisions of these Articles of
Incorporation, as determined from time to time by the Board of Directors and
stated in the resolution or resolutions providing for the issuance thereof,
prior to the issuance of any shares thereof. The Board of Directors shall have
the authority to fix and determine and to amend, subject to the provisions
hereof, the designation, preferences, limitations and relative rights of the
shares of any series that is wholly unissued or to be established. Unless
otherwise specifically provided in the resolution establishing any series, the
Board of Directors shall further have the authority, after the issuance of
shares of a series whose number it has designated, to amend the resolution
establishing such series to decrease the number of shares of that series, but
not below the number of shares of such series then outstanding.

        4.3    DIVIDENDS

receive dividends, out of the funds of the corporation legally available
therefor, at the rate and at the time or times, whether cumulative or
noncumulative, as may be provided by the Board of Directors in designating a
particular series of Preferred Stock. If such dividends on the Preferred Stock
shall be cumulative, then if dividends shall not have been paid, the deficiency
shall be fully paid or the dividends declared and set apart for payment at such
rate, but without interest on cumulative dividends, before any dividends on the
Common Stock shall be paid or declared and set apart for payment. The holders of
the Preferred Stock shall not be entitled to receive any dividends thereon other
than the dividends referred to in this section.

        4.4    REDEMPTION

        The Preferred Stock may be redeemable at such price, in such amount, and
at such time or times as may be provided by the Board of Directors in
designating a particular series of Preferred Stock. In any event, such Preferred
Stock may be repurchased by this corporation to the extent legally permissible.

        4.5    LIQUIDATION

        In the event of any liquidation, dissolution or winding up of the
affairs of this corporation, whether voluntary or involuntary, then, before any
distribution shall be made to the holders of the Common Stock, the holders of
the Preferred

                              ARTICLE 9. DIRECTORS

        The number of Directors of this corporation shall be determined in the
manner provided by the Bylaws and may be increased or decreased from time to
time in the manner provided therein. The Board of Directors shall be divided
into three classes, with said classes to be as equal in number as may be

shareholders, each Class 2 Director shall be elected to serve until the second
ensuing annual meeting of shareholders and each Class 3 Director shall be

Notwithstanding any of the foregoing provisions of this Article 9, Directors

earlier death, resignation or removal from office, or until there is a decrease
in the number of Directors.

        The Directors of this corporation may be removed only for cause by the

any of the provisions contained in these Articles of Incorporation; provided
that Article 1 ("Name"), Article 2 ("Duration"), Article 3 ("Purposes and
Powers"), Article 4 ("Shares"), Article 8 ("Registered Office and Agent") and
Article 11 ("Incorporator") may be amended in any manner now or hereafter
permitted by law. The rights of the shareholders of this corporation are granted
subject to this reservation; provided, however, that the holders of the

proposed amendment if the amendment would increase or decrease the aggregate
number of authorized shares of such class, increase or decrease the par value of
the shares of such class, or alter or change the powers, preferences or special
rights of the shares of such class so as to affect them adversely. If any
proposed amendment would alter or change the powers, preferences or special
rights of one or more series of any class so as to affect them adversely, but
shall not affect the entire class, then only the shares of the series so
affected by the amendment shall be considered as a separate class for the
purposes of this Article 10. Irrespective of the provisions of this Article 10,
the number of authorized shares of any such class or classes of stock may be
increased by the affirmative vote of the holders of two-thirds of the stock of
this corporation entitled to vote thereon or decreased (but not below the number
of shares thereof then outstanding) by the affirmative vote of the holders of a
majority of the stock of this corporation entitled to vote thereon, if so
provided in any amendment which created such class or classes of stock or which
was adopted prior to the issuance of any shares of such class or classes of
stock, or in any amendment which was authorized by a resolution or resolutions
adopted by the affirmative vote of the holders of two-thirds of such class or
classes of stock.

                  ARTICLE 12. LIMITATION OF DIRECTOR LIABILITY

        To the full extent that the Washington Business Corporation Act, as it
exists on the date hereof or may hereafter be amended, permits the limitation or
elimination of the liability of Directors, a Director of this corporation shall

        4.8    DESIGNATION OF RIGHTS AND PREFERENCES OF SERIES A JUNIOR
               PARTICIPATING PREFERRED STOCK

        The following series of Preferred Stock is hereby designated, which
series shall have the rights, preferences, privileges and limitations as set
forth below:

        4.8.1. Designation of Series A Junior Participating Preferred Stock and
Amount. The shares of such series shall be designated as "Series A Junior
Participating Preferred Stock" (the "Series A Preferred Stock") and the number
of shares constituting the Series A Preferred Stock shall be 450,000. Such
number of shares may be increased or decreased by resolution of the Board of
Directors; provided, however, that no decrease shall reduce the number of shares
of Series A Preferred Stock to a number less than the number of shares then
outstanding plus the number of shares reserved for issuance upon the exercise of
outstanding options, rights or warrants or upon the conversion of any
outstanding securities issued by the corporation convertible into Series A
Preferred Stock.

        4.8.2. Dividends and Distributions.

               (A) Subject to the rights of the holders of any shares of any
series of Preferred Stock (or any similar stock) ranking prior and superior to
the Series A Preferred Stock with respect to dividends, the holders of shares of
Series A Preferred Stock, in preference to the holders of Common Stock, no par
value per share (the "Common Stock"), of the corporation, and of any other
junior stock, shall be entitled to receive, when, as and if declared by the
Board of Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the first day of March, June, September and
December in each year (each such date being referred to herein as a "Quarterly
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
after the first issuance of a share or fraction of a share of Series A Preferred
Stock, in an amount per share (rounded to the nearest cent) equal to the greater
of (i) $1 and (ii) subject to the provision for adjustment hereinafter set
forth, 100 times the aggregate per share amount of all cash dividends, and 100
times the aggregate per share amount (payable in kind) of all non-cash dividends
or other distributions, other than a dividend payable in shares of Common Stock
or a subdivision of the outstanding shares of Common Stock (by reclassification
or otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of a share of
Series A Preferred Stock. 

                                                                               1
<PAGE>   21


In the event the corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (ii) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

               (B) The corporation shall declare a dividend or distribution on
the Series A Preferred Stock as provided in paragraph (A) of this Section 4.8.2
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided, however,
that, in the event no dividend or distribution shall have been declared on the
Common Stock during the period between any Quarterly Dividend Payment Date and
the next subsequent Quarterly Dividend Payment Date, a dividend of $1 per share
on the Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

               (C) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series A Preferred Stock in
an amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding. The Board of Directors may fix a
record date for the determination of holders of shares of Series A Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than 60 days prior to the date
fixed for the payment thereof.


                                                                               2

<PAGE>   22

        4.8.3. Voting Rights. The holders of shares of Series A Preferred Stock
shall have the following voting rights:

               (A) Subject to the provision for adjustment hereinafter set
forth, each share of Series A Preferred Stock shall entitle the holder thereof
to 100 votes on all matters submitted to a vote of the shareholders of the
corporation. In the event the corporation shall at any time declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the number of votes per share to which holders of shares of
Series A Preferred Stock were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction, the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

               (B) Except as otherwise provided herein, in any other Articles of
Amendment creating a series of Preferred Stock or any similar stock, or by law,
the holders of shares of Series A Preferred Stock and the holders of shares of
Common Stock and any other capital stock of the corporation having general
voting rights shall vote together as one class on all matters submitted to a
vote of shareholders of the corporation.

               (C) Except as set forth herein, or as otherwise provided by law,
holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for taking any corporate
action.

        4.8.4. Certain Restrictions.

               (A) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Preferred Stock as provided in Section
4.8.2 are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Stock
outstanding shall have been paid in full, the corporation shall not:

                       (i) declare or pay dividends, or make any other
        distributions, on any shares of stock ranking junior (either as to
        dividends or upon liquidation, dissolution or winding up) to the Series
        A Preferred Stock;


                                                                               3
<PAGE>   23

                      (ii) declare or pay dividends, or make any other
        distributions, on any shares of stock ranking on a parity (either as to
        dividends or upon liquidation, dissolution or winding up) with the
        Series A Preferred Stock, except dividends paid ratably on the Series A
        Preferred Stock and all such parity stock on which dividends are payable
        or in arrears in proportion to the total amounts to which the holders of
        all such shares are then entitled;

                     (iii) redeem or purchase or otherwise acquire for
        consideration shares of any stock ranking junior (either as to dividends
        or upon liquidation, dissolution or winding up) to the Series A
        Preferred Stock, provided that the corporation may at any time redeem,
        purchase or otherwise acquire shares of any such junior stock in
        exchange for shares of any stock of the corporation ranking junior
        (either as to dividends or upon dissolution, liquidation or winding up)
        to the Series A Preferred Stock; or

                      (iv) redeem or purchase or otherwise acquire for
        consideration any shares of Series A Preferred Stock, or any shares of
        stock ranking on a parity with the Series A Preferred Stock, except in
        accordance with a purchase offer made in writing or by publication (as
        determined by the Board of Directors) to all holders of such shares upon
        such terms as the Board of Directors, after consideration of the
        respective annual dividend rates and other relative rights and
        preferences of the respective series and classes, shall determine in
        good faith will result in fair and equitable treatment among the
        respective series or classes.

               (B) The corporation shall not permit any subsidiary of the
corporation to purchase or otherwise acquire for consideration any shares of
stock of the corporation unless the corporation could, under paragraph (A) of
this Section 4.8.4, purchase or otherwise acquire such shares at such time and
in such manner.

        4.8.5. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Articles of Incorporation, or in any other Articles of Amendment creating a
series of Preferred Stock or any similar stock or as otherwise required by law.

        4.8.6. Liquidation, Dissolution or Winding Up. Upon any liquidation,
dissolution or winding up of the corporation, no distribution shall be made (a)
to the 

                                                                               4
<PAGE>   24

holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received $100 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment,
provided that the holders of shares of Series A Preferred Stock shall be
entitled to receive an aggregate amount per share, subject to the provision for
adjustment hereinafter set forth, equal to 100 times the aggregate amount to be
distributed per share to holders of shares of Common Stock, or (b) to the
holders of shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Preferred Stock,
except distributions made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled upon such liquidation, dissolution or winding up. In the
event the corporation shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the aggregate amount to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event under the proviso in clause
(a) of the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

        4.8.7. Consolidation, Merger, etc. In case the corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of

                                                                               5
<PAGE>   25

2.6     BUSINESS FOR SHAREHOLDERS' MEETINGS

        2.6.1  BUSINESS AT ANNUAL MEETINGS

        In addition to the election of directors, other proper business may be
transacted at an annual meeting of shareholders, provided that such business is
properly brought before such meeting. To be properly brought before an annual
meeting, business must be (a) brought by or at the direction of the Board or (b)
brought before the meeting by a shareholder pursuant to written notice thereof,
in accordance with subsection 2.6.3 hereof, and received by the Secretary not
fewer than sixty nor more than ninety days prior to the date specified in
subsection 2.1 hereof for such annual meeting (or if less than sixty days'
notice or prior public disclosure of the date of the annual meeting is given or
made to the shareholders, not later than the tenth day following the day on
which the notice of the date of the annual meeting was mailed or such public
disclosure was made). Any such shareholder notice shall set forth (i) the name
and address of the shareholder proposing such business; (ii) a representation
that the shareholder is entitled to vote at such meeting and a statement of the
number of shares of the corporation which are beneficially owned by the
shareholder; (iii) a representation that the shareholder intends to appear in
person or by proxy at the meeting to propose such business; and (iv) as to each
matter the shareholder proposes to bring before the meeting, a brief description
of the business desired to be brought before the meeting, the reasons for
conducting such business at the meeting, the language of the proposal (if
appropriate), and any material interest of the shareholder in such business. No
business shall be conducted at any annual meeting of shareholders except in
accordance with this subsection 2.6.1. If the facts warrant, the Board, or the
chairman of an annual meeting of shareholders, may determine and declare (a)
that a proposal does not constitute proper business to be transacted at the
meeting or (b) that business was not properly brought before the meeting in
accordance with the provisions of this subsection 2.6.1 and, if, in either case,
it is so determined, any such business shall not be transacted. The procedures
set forth in this subsection 2.6.1 for business to be properly brought before an
annual meeting by a shareholder are in addition to, and not in lieu of, the
requirements set forth in Rule 14a-8 under Section 14 of the Securities Exchange
Act of 1934, as amended, or any successor provision.

        2.6.2  BUSINESS AT SPECIAL MEETINGS

        At any special meeting of the shareholders, only such business as is
specified in the notice of such special meeting given by or at the direction of
the person or persons calling

such meeting, in accordance with subsection 2.5 hereof, shall come before such
meeting.

        2.6.3  NOTICE TO CORPORATION

        Any written notice required to be delivered by a shareholder to the
corporation pursuant to subsection 2.5, subsection 2.6.1 or subsection 2.6.2
hereof must be given, either by personal delivery or by registered or certified
mail, postage prepaid, to the Secretary at the corporation's executive offices
in the City of Redmond, State of Washington.

2.7     WAIVER OF NOTICE

        Whenever any notice is required to be given to any shareholder under the
provisions of these Bylaws, the Articles of Incorporation or the Washington
Business Corporation Act, a waiver thereof in writing, signed by the person or
persons entitled to such notice and delivered to the corporation, whether before
or after the date and time of the meeting, shall be deemed equivalent to the
giving of such notice. Further, notice of the time, place and purpose of any
meeting will be deemed to be waived by any shareholder by attendance thereat in
person or by proxy, unless such shareholder at the beginning of the meeting
objects to holding the meeting or transacting business at the meeting.

2.8     FIXING OF RECORD DATE FOR DETERMINING SHAREHOLDERS

        For the purpose of determining shareholders entitled (a) to notice of or
to vote at any meeting of shareholders or any adjournment thereof, (b) to demand
a special meeting, or (c) to receive payment of any dividend, or in order to
make a determination of shareholders for any other purpose, the Board may fix a
future date as the record date for any such determination. Such record date
shall be not more than 70 days, and in case of a meeting of shareholders not
less than 10 days prior to the date on which the particular action requiring
such determination is to be taken.

2.9     VOTING RECORD

        At least ten days before each meeting of shareholders, an alphabetical
list of the shareholders entitled to notice of such meeting shall be made,
arranged by voting group and by each class or series of shares therein, with the
address of and number of shares held by each shareholder. This record shall be
kept at the principal office of the corporation for ten days prior to such
meeting, and shall be kept open at such

meeting, for the inspection of any shareholder or any shareholder's agent.

2.10    QUORUM

        A majority of the votes entitled to be cast on a matter by the holders
of shares that, pursuant to the Articles of Incorporation or the Washington
Business Corporation Act, are entitled to vote and be counted collectively upon
such matter, represented in person or by proxy, shall constitute a quorum of
such shares at a meeting of shareholders. If less than a majority of such votes
are represented at a meeting, a majority of the votes so represented may adjourn
the meeting from time to time without further notice if the new date, time or
place is announced at the meeting before adjournment. Any business may be
transacted at a reconvened meeting that might have been transacted at the
meeting as originally called, provided a quorum is present or represented
thereat. Once a share is represented for any purpose at a meeting other than
solely to object to holding the meeting or transacting business thereat, it is
deemed present for quorum purposes for the remainder of the meeting and any
adjournment thereof (unless a new record date is or must be set for the
adjourned meeting) notwithstanding the withdrawal of enough shareholders to
leave less than a quorum.

2.11    MANNER OF ACTING

        If a quorum is present, action on a matter other than the election of
Directors shall be approved if the votes cast in favor of the action by the
shares entitled to vote and be counted collectively upon such matter exceed the
votes cast against such action by the shares entitled to vote and be counted
collectively thereon, unless the Articles of Incorporation or the Washington
Business Corporation Act requires a greater number of affirmative votes.

2.12    PROXIES

        A shareholder may vote by proxy executed in writing by the shareholder
or by his or her attorney-in-fact or agent. Such proxy shall be effective when
received by the Secretary or other officer or agent authorized to tabulate
votes. A proxy shall become invalid 11 months after the date of its execution,
unless otherwise provided in the proxy. A proxy with respect to a specified
meeting shall entitle the holder thereof to vote at any reconvened meeting
following adjournment of such meeting but shall not be valid after the final
adjournment thereof.

2.13    VOTING OF SHARES

        Except as provided in the Articles of Incorporation or in Section 2.14
hereof, each outstanding share entitled to vote with respect to a matter
submitted to a meeting of shareholders shall be entitled to one vote upon such
matter.

2.14    VOTING FOR DIRECTORS

        Each shareholder entitled to vote at an election of Directors may vote,
in person or by proxy, the number of shares owned by such shareholder for as
many persons as there are Directors to be elected and for whose election such
shareholder has a right to vote. Unless otherwise provided in the Articles of
Incorporation or in Section 3.14 hereof, the candidates elected shall be those
receiving the largest number of votes cast, up to the number of Directors to be
elected.

2.15    ACTION BY SHAREHOLDERS WITHOUT A MEETING

        Any action which could be taken at a meeting of the shareholders may be
taken without a meeting if one or more written consents setting forth the action
so taken are signed by all shareholders entitled to vote on the action and are
delivered to the corporation. If not otherwise fixed by the Board, the record
date for determining shareholders entitled to take action without a meeting is
the date the first shareholder signs the consent. A shareholder may withdraw a
consent only by delivering a written notice of withdrawal to the corporation
prior to the time that all consents are in the possession of the corporation.
Action taken by written consent of shareholders without a meeting is effective
when all consents are in the possession of the corporation, unless the consent
specifies a later effective date. Any such consent shall be inserted in the
minute book as if it were the minutes of a meeting of the shareholders.

                          SECTION 3. BOARD OF DIRECTORS

3.1     GENERAL POWERS

        All corporate powers shall be exercised by or under the authority of,
and the business and affairs of the corporation shall be managed under the
direction of, the Board, except as may be otherwise provided in these Bylaws,

resolution of the Board. The number of Directors may be changed from time to
time by amendment to these Bylaws, but no decrease in the number of Directors
shall have the effect of shortening the term of any incumbent Director.
Directors need not be shareholders of the corporation or residents of the State
of Washington and need not meet any other qualifications.

        The Board of Directors shall be divided into three classes, with said
classes to be as equal in number as may be possible. At the first election of
Directors to such classified Board of Directors, each Class 1 Director shall be
elected to serve until the next ensuing annual meeting of shareholders, each
Class 2 Director shall be elected to serve until the second ensuing annual
meeting of shareholders and each Class 3 Director shall be elected to serve
until the third ensuing annual meeting of shareholders. At each annual meeting
of shareholders following the meeting at which the Board of Directors is
initially classified, the number of Directors equal to the number of Directors
in the class whose term expires at the time of such meeting shall be elected to
serve until the third ensuing annual meeting of shareholders. Notwithstanding
any of the foregoing provisions of this Section 3.2, Directors shall serve until
their successors are elected and qualified or until their earlier death,
resignation or removal from office or until there is a decrease in the number of
Directors.

3.3     NOMINATION AND ELECTION.

        3.3.1  NOMINATION

        Only persons who are nominated in accordance with the following
procedures shall be eligible for election as Directors. Nominations for the
election of Directors may be made (a) by or at the direction of the Board or (b)
by any shareholder of record entitled to vote for the election of Directors at
such meeting; provided, however, that a shareholder may nominate persons for
election as Directors only if written notice (in accordance with subsection
2.6.3 hereof) of such shareholder's intention to make such nominations is
received by the Secretary not later than (i) with respect to an election to be
held at an annual meeting of the shareholders, not fewer than sixty nor more
than ninety days prior to the date specified in subsection 2.1 hereof for such
annual meeting (or if less than sixty days' notice or prior public disclosure of
the date of the annual meeting is given or made to the shareholders, not later
than the tenth day following the day on which such notice of the date of the
annual meeting was mailed or such public disclosure was made) and (ii) with

the close of business on the seventh business day following the date on which
notice of such meeting is first given to shareholders. Any such shareholder's
notice shall set forth (a) the name and address of the shareholder who intends
to make a nomination; (b) a representation that the shareholder is entitled to
vote at such meeting and a statement of the number of shares of the corporation
which are beneficially owned by the shareholder; (c) a representation that the
shareholder intends to appear in person or by proxy at the meeting to nominate
the person or persons specified in the notice; (d) as to each person the
shareholder proposes to nominate for election or re-election as a Director, the
name and address of such person and such other information regarding such
nominee as would be required in a proxy statement filed pursuant to the proxy
rules of the Securities and Exchange Commission had such nominee been nominated
by the Board, and a description of any arrangements or understandings, between
the shareholder and such nominee and any other persons (including their names),
pursuant to which the nomination is to be made; and (e) the consent of each such
nominee to serve as a Director if elected. If the facts warrant, the Board, or
the chairman of a shareholders' meeting at which Directors are to be elected,
shall determine and declare that a nomination was not made in accordance with
the foregoing procedure and, if it is so determined, the defective nomination
shall be disregarded. The right of shareholders to make nominations pursuant to
the foregoing procedure is subject to the rights of the holders of any class or
series of stock having a preference over the Common Stock as to dividends or
upon liquidation. The procedures set forth in this subsection 3.3 for nomination
for the election of Directors by shareholders are in addition to, and not in
limitation of, any procedures now in effect or hereafter adopted by or at the
direction of the Board or any committee thereof.

        3.3.2  ELECTION

        At each election of Directors, the persons receiving the greatest number
of votes shall be the Directors.

without the State of Washington for holding regular meetings thereof without
notice other than such resolution.

holding the meeting or transacting business thereat and does not thereafter vote
for or assent to action taken at the meeting.

meeting from time to time without further notice.

3.10    MANNER OF ACTING

        If a quorum is present when the vote is taken, the act of the majority

action taken unless (a) the Director objects at the beginning of the meeting, or
promptly upon the Director's arrival, to holding the meeting or transacting any
business thereat, (b) the Director's dissent or abstention from the action taken
is entered in the minutes of the meeting, or (c) the Director delivers written
notice of the Director's dissent or abstention to the presiding officer of the
meeting before its adjournment or to the corporation within a reasonable time
after adjournment of the meeting. The right of dissent or abstention is not
available to a Director who votes in favor of the action taken.

3.12    ACTION BY BOARD OR COMMITTEES WITHOUT A MEETING

        Any action which could be taken at a meeting of the Board or of any
committee created by the Board may be taken without a meeting if one or more
written consents setting forth the action so taken are signed by each of the
Directors or by each committee member either before or after the action is taken
and delivered to the corporation. Action taken by written consent of Directors
without a meeting is effective when the last Director signs the consent, unless

meeting.

3.14    REMOVAL

        Any Director or the entire Board may be removed for cause by the holders
of not less than two-thirds of the shares entitled to elect the Director or
Directors whose removal is sought. Such action may only be taken at a special
meeting of the shareholders called expressly for that purpose, providing that
notice of the proposed removal, which shall include a statement of the charges
alleged against the Director, shall have been duly given to the shareholders
together with or as a part of the notice of the meeting.

        Where a question of the removal of a Director for cause is to be
presented for shareholder consideration, an opportunity must be provided to such
Director to present his or her defense to the shareholders by a statement which
must accompany or precede the notice of the special meeting of shareholders or,
if provided to shareholders prior to the notice of the special meeting, the
initial solicitation of proxies seeking authority to vote for the removal of
such Director for cause. If not provided, then such proxies may not be voted for
removal. The Director involved shall be served with notice of the meeting at
which such action is proposed to be taken together with a statement of the
specific charges and shall be given an opportunity to be present and to be heard
at the meeting at which his or her removal is considered.

        The vacancy created by the removal of a Director under this Section 3.14
shall be filled only by a vote of the holders of two-thirds of the shares then

meeting at which the removal of such Director was accomplished, or at such later
meeting, regular or special, as the shareholders may decide.

of Incorporation provide otherwise, any vacancy occurring on the Board may be

fewer than a quorum, by the affirmative vote of a majority of the remaining
Directors. Any vacant office held by a Director elected by the holders of one or
more classes or series of shares entitled to vote and be counted collectively
thereon shall be filled only by the vote of the holders of such class or series
of shares. A Director elected to fill a

10.1    RIGHT TO INDEMNIFICATION

        Each person who was, is or is threatened to be made a named party to or
is otherwise involved (including, without limitation, as a witness) in any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative and whether formal or informal
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
Director or officer of the corporation or, that being or having been such a
Director or officer or an employee of the corporation, he or she is or was
serving at the request of the corporation as a Director, officer, partner,
trustee, employee or agent of another corporation or of a partnership, joint
venture, trust, employee benefit plan or other enterprise (hereinafter an
"indemnitee"), whether the basis of a proceeding is alleged action in an
official capacity as such a Director, officer, partner, trustee, employee or
agent or in any other capacity while serving as such a Director, officer,
partner, trustee, employee or agent, shall be indemnified and held harmless by
the corporation against all expense, liability and loss (including counsel fees,
judgments, fines, ERISA excise taxes or penalties and amounts to be paid in
settlement) actually and reasonably incurred or suffered by such indemnitee in
connection therewith, and such indemnification shall continue as to an
indemnitee who has ceased to be a Director, officer, partner, trustee, employee
or agent and shall inure to the benefit of the indemnitee's heirs, executors and
administrators. Except as provided in subsection 10.2 of this Section with
respect to proceedings seeking to enforce rights to indemnification, the
corporation shall indemnify any such indemnitee in connection with a proceeding
(or part thereof) initiated by such indemnitee only if a proceeding (or part
thereof) was authorized or ratified by the Board. The right to indemnification
conferred in this Section shall be a contract right.

10.2    RESTRICTIONS ON INDEMNIFICATION

        No indemnification shall be provided to any such indemnitee for acts or
omissions of the indemnitee finally adjudged to be intentional misconduct or a
knowing violation of law, for conduct of the indemnitee finally adjudged to be
in violation of Section 23B.08.310 of the Washington Business Corporation Act,
for any transaction with respect to which it was finally adjudged that such
indemnitee personally received a benefit in money, property or services to which
the indemnitee was not legally entitled or if the corporation is otherwise
prohibited by applicable law from paying such

indemnification, except that if Section 23B.08.560 or any successor provision of
the Washington Business Corporation Act is hereafter amended, the restrictions
on indemnification set forth in this subsection 10.2 shall be as set forth in
such amended statutory provision.

10.3    ADVANCEMENT OF EXPENSES

        The right to indemnification conferred in this Section shall include the
right to be paid by the corporation the expenses incurred in defending any
proceeding in advance of its final disposition (hereinafter an "advancement of
expenses"). An advancement of expenses shall be made upon delivery to the
corporation of an undertaking (hereinafter an "undertaking"), by or on behalf of
such indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal that such indemnitee is not entitled to be indemnified for such expenses
under this subsection 10.3.

10.4    RIGHT OF INDEMNITEE TO BRING SUIT

        If a claim under subsection 10.1 or 10.3 of this Section is not paid in
full by the corporation within 60 days after a written claim has been received
by the corporation, except in the case of a claim for an advancement of
expenses, in which case the applicable period shall be 20 days, the indemnitee
may at any time thereafter bring suit against the corporation to recover the
unpaid amount of the claim. If successful in whole or in part, in any such suit
or in a suit brought by the corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the indemnitee shall be entitled to be
paid also the expense of prosecuting or defending such suit. The indemnitee
shall be presumed to be entitled to indemnification under this Section upon
submission of a written claim (and, in an action brought to enforce a claim for
an advancement of expenses, where the required undertaking has been tendered to
the corporation) and thereafter the corporation shall have the burden of proof
to overcome the presumption that the indemnitee is so entitled.

10.5    PROCEDURES EXCLUSIVE

        Pursuant to Section 23B.08.560(2) or any successor provision of the
Washington Business Corporation Act, the procedures for indemnification and
advancement of expenses set forth in this Section are in lieu of the procedures
required by Section 23B.08.550 or any successor provision of the Washington
Business Corporation Act.

10.6    NONEXCLUSIVITY OF RIGHTS

        The right to indemnification and the advancement of expenses conferred
in this Section shall not be exclusive of any other right which any person may
have or hereafter acquire under any statute, provision of the Articles of
Incorporation or Bylaws of the corporation, general or specific action of the
Board, contract or otherwise.

        The corporation may maintain insurance, at its expense, to protect
itself and any Director, officer, partner, trustee, employee or agent of the
corporation or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the Washington Business Corporation Act. The corporation
may enter into contracts with any Director, officer, partner, trustee, employee
or agent of the corporation in furtherance of the provisions of this Section and
may create a trust fund, grant a security interest or use other means
(including, without limitation, a letter of credit) to ensure the payment of
such amounts as may be necessary to effect indemnification as provided in this
Section.

        The corporation may, by action of the Board, grant rights to
indemnification and advancement of expenses to employees and agents or any class
or group of employees and agents of the corporation (i) with the same scope and
effect as the provisions of this Section with respect to the indemnification and
advancement of expenses of Directors and officers of the corporation; (ii)
pursuant to rights granted pursuant to, or provided by, the Washington Business
Corporation Act; or (iii) as are otherwise consistent with law.

10.9    PERSONS SERVING OTHER ENTITIES

corporation, is or was serving as a Director or officer of another foreign or
domestic corporation of which a majority of the shares entitled to vote in the
election of its Directors is held by the corporation shall be deemed to be so

Directors of the Company is March 11, 1998. The effective date of this Amendment

                               AMENDMENT NO. 1 TO
                             WALL DATA INCORPORATED
                           1993 STOCK OPTION PLAN FOR
                             NON-EMPLOYEE DIRECTORS
                   AS AMENDED AND RESTATED ON OCTOBER 15, 1996



        The Wall Data Incorporated 1993 Stock Option Plan For Non-Employee
Directors (the "Plan") is amended as follows:

        1.     Section 4 of the Plan is amended to add a new third paragraph as
               follows:

               In addition to the options set forth in the preceding paragraph
               and effective October 28, 1997, Robert Frankenberg shall
               automatically receive the grant of an option (the "Frankenberg
               Option") to purchase 30,000 shares. The Frankenberg Option shall
               vest and become exercisable over 3 years, one-third at each
               anniversary date, except that vesting shall be based on Mr.
               Frankenberg's period of continuous service as the Company's
               outside Chairman of the Board rather than on his service as a
               director. The Frankenberg Option shall terminate six (6) years
               from the date of grant and otherwise in accordance with Section
               5.5 of the Plan, except that early termination shall be based on
               Mr. Frankenberg's service as the Company's outside Chairman of
               the Board rather than on his service as a director.



        The date of the adoption of this Amendment No. 1 by the Board of
Directors of the corporation is October 28, 1997. The effective date of this
Amendment No. 1 shall be October 28, 1997, the date of adoption by the Board of
Directors.

                    SEPARATION AGREEMENT AND GENERAL RELEASE

        THIS SEPARATION AGREEMENT AND GENERAL RELEASE (the "Agreement") is
entered into as of June 30, 1997, by James Simpson (hereinafter referred to as
"Simpson") and Wall Data Incorporated (hereinafter referred to as "Wall Data").

                                    RECITALS

        A. Simpson has served as Chairman of the Board ("Chairman") and Chief
Executive Officer ("CEO") of Wall Data. Effective July 31, 1997, Simpson will
resign as Chairman and CEO of Wall Data, and, effective October 31, 1997,
Simpson's employment relationship with Wall Data will terminate.

        B. Simpson and Wall Data wish to enter into an agreement to clarify and
resolve any disputes that may exist between them arising out of the board
relationship and employment relationship and their termination, and any
continuing obligations of the parties to one another following the end of these
relationships.

        C. Wall Data has advised Simpson of Simpson's right to consult an
attorney prior to signing this Agreement and has provided Simpson with up to 21
days to consider its severance offer and to seek legal assistance. Simpson has
consulted an attorney of Simpson's choice and understands that Simpson is
waiving all potential claims against Wall Data.

                                   AGREEMENTS

        NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual promises contained below, it is agreed as follows:



<PAGE>   2




1.      EMPLOYMENT: ENDING DATE AND RESPONSIBILITIES

        Simpson's service as Chairman and CEO of Wall Data will terminate
effective July 31, 1997. Simpson shall remain an employee of Wall Data until
October 31, 1997, at his current salary and benefits. Effective October 31,
1997, Simpson will have no further employment or board duties or
responsibilities to Wall Data, except as may be specifically set forth herein.

2.      CHARACTERIZATION OF TERMINATION

        Simpson and Wall Data agree that Simpson's termination of employment and
board service is a voluntary resignation and shall be characterized as such for
all future purposes.

3.      SEVERANCE AND BENEFITS

        On July 31, 1997, Wall Data will pay to Simpson a lump sum payment of
Five Hundred Twenty-Five Thousand Dollars ($525,000.00). Similarly, on July 31,
1997, Wall Data will also pay to Simpson an additional payment of Eighty-Seven
Thousand Five Hundred Dollars ($87,500.00) as the pro rata portion of Simpson's
cash bonus for calendar year 1997, based on the amount of time he was employed
as CEO during the year. Simpson will continue to receive his full salary,
payable on Wall Data's normal payroll schedule, through October 31, 1997. On
that date, Simpson will be paid his final paycheck, which will include any
accrued but unused vacation time. Wall Data will also pay on Simpson's behalf,
Simpson's COBRA payments for the period beginning November 1, 1997 until May 1,
1999, or until Simpson becomes eligible for coverage under another employer's
medical plan, whichever occurs first. All other benefits shall cease effective
the date that Simpson's employment terminates (October 31, 1997).

                                      -2-

<PAGE>   3


4.      STOCK OPTIONS

        a. Wall Data will recommend to the Compensation Committee that at its
next meeting the Committee consider accelerating the vesting of Simpson's
employee stock options listed on Exhibit A (the "Options"), which represent all
of Simpson's unvested options effective as of October 31, 1997, so that such
options are fully vested at the close of business on July 15, 1997. Wall Data
will also extend the post-termination exercise period for the Options, so that
the Options will remain exercisable until and including October 31, 1999, at
which time they will expire. Simpson understands that these modifications will
disqualify the options listed on Exhibit A as incentive stock options under the
Internal Revenue Code of 1986 (the "IRC"), as amended, and that such options
will become nonqualified stock options.

        b. Exhibit A also sets forth Simpson's employee stock options which,
absent the acceleration of vesting provided for in subparagraph (a) above, will
be vested as of October 31, 1997 (taking into account Simpson's continued
employment by Wall Data through that date). In accordance with the applicable
stock option plan, such options will continue to vest until October 31, 1997,
and will remain exercisable for ninety (90) days, at which time they will
expire. Such options are and will qualify as incentive stock options under the
IRC, absent any disqualifying event by Simpson.

        c. Wall Data agrees that the following shall apply with respect to any
and all shares of Wall Data issued upon exercise of any of the stock options
referenced in subparagraphs (a) and (b) above:

                i. The Company will use its best efforts to undertake all action
to maintain the effectiveness of the registration of such shares under the
Securities Act of 1933, as amended, pursuant to one or more Registration
Statements on Form S-9 (or any successor form).


                                      -3-
<PAGE>   4




               ii. Because the stock option plan(s) under which the foregoing
options were issued qualify under Securities and Exchange Commission ("SEC")
Rule 16b-3, and assuming that Simpson did not purchase any Wall Data shares
within the six-month period preceding July 31, 1997, any trading profits on
sales of any of the shares issued upon exercise of the foregoing options will
not be subject to the recapture provisions of Section 16(b) of the Securities
Exchange Act of 1934, as amended; and

              iii. To the best of the Company's knowledge, Simpson will not be
required to file Form 4's or Form 144's with the SEC in connection with his
sales of such shares.

5.      VALID CONSIDERATION

        Simpson and Wall Data agree that payments by Wall Data to Simpson
herein, as well as the acceleration of vesting and extension of post-termination
exercise periods offered in Paragraph No. 4 above, are not required by Wall Data
policies or procedures or by any contractual obligation of Wall Data, and are
offered by Wall Data solely as consideration for this Agreement.

6.      NONCOMPETITION

        Simpson agrees that for a period of one year from the date this
Agreement is executed, he will not be employed by, consult with or otherwise
perform services for any entity who directly competes with Wall Data, wherein
Simpson's employment, consultantship or the provision of his services would
involve or relate to terminal emulation technology, excluding any InterNet
solution to host-to-PC connectivity, other than any product that directly
competes with Arpeggio Live by providing: (a) legacy system connectivity, or (b)
the formatting of data from industry standard data bases. For its part, Wall
Data specifically acknowledges that this noncompetition provision would not bar
Simpson from accepting employment with, consulting for or otherwise

                                      -4-

<PAGE>   5




providing services to any entity so long as he does not engage in the
competitive activity described in this paragraph.

7.      NONSOLICITATION

        Simpson shall not, for a period of one (1) year from the date this
Agreement is executed, anywhere in the world, directly or indirectly solicit,
influence or entice, or attempt to solicit, influence or entice, any employee or
consultant of Wall Data to cease his or her relationship with Wall Data or
solicit, influence, entice or in any way divert any customer, distributor,
partner, joint venturer or supplier of Wall Data to do business or in any way
become associated with any Competitor.

8.      REAFFIRMATION OF CONFIDENTIALITY AGREEMENT AND INDEMNIFICATION AGREEMENT

        Simpson agrees to sign, and expressly reaffirms and incorporates herein
as part of this Agreement the Confidential Information and Inventions Agreement,
or other such agreement that Simpson signed as part of his employment with Wall
Data, copies of which are attached as Exhibit B and which shall remain in full
effect. Wall Data agrees that the Indemnification Agreement that Simpson signed
as part of his employment with Wall Data, a copy of which is attached as Exhibit
C, shall remain in full force and effect and shall cover all of Simpson's
activities as an officer, director and/or employee of Wall Data in accordance
with its terms.

9.      GENERAL RELEASE OF CLAIMS

        Simpson expressly waives any claims against Wall Data and releases Wall
Data (including its officers, directors, shareholders, managers, agents and
representatives) from any claims, known or unknown, that Simpson may have in any
way connected with Simpson's employment or board service with Wall Data and the
termination thereof. It is understood that


                                      -5-
<PAGE>   6




this release includes, but is not limited to, any claims for wages, bonuses,
employment benefits, stock options other than what is provided herein, or
damages of any kind whatsoever, arising out of any contracts, express or
implied, any covenant of good faith and fair dealing, express or implied, any
theory of wrongful discharge, any legal restriction on Wall Data's right to
terminate employees, or any federal, state or other governmental statute or
ordinance, including, without limitation, Title VII of the Civil Rights Act of
1964, the federal Age Discrimination in Employment Act, the Americans with
Disabilities Act, the Washington Law Against Discrimination, or any other legal
limitation on the employment relationship.

        It is the intention of the parties in executing this Agreement that this
release shall be effective as a bar to each and every claim, demand, or cause of
action released hereby. Simpson recognizes that he may have some claim, demand,
or cause of action against Wall Data of which he is totally unaware and
unsuspecting, which he is giving up by execution of this Agreement. Simpson's
intention in executing this instrument that it will deprive Simpson of each such
claim, demand or cause of action and prevent him from asserting same against
Wall Data. In furtherance of this intention, Simpson expressly waives any rights
or benefits conferred by the provisions of Section 1542 of the California Civil
Code or any similar statute of any other jurisdiction. California Civil Code
Section 1542, provides as follows:

               "A general release does not extend to claims which the creditor
               does not know or suspect to exist in his favor at the time of
               executing the release, which if known by him must have materially
               affected his settlement with the debtor."

                                      -6-

<PAGE>   7




        Simpson represents that Simpson has not filed any complaints, charges or
lawsuits against Wall Data with any governmental agency or any court, and agrees
that Simpson will not initiate, assist or encourage any such actions.

        This waiver and release shall not preclude Simpson from filing a lawsuit
for the exclusive purpose of enforcing Simpson's rights under this Agreement.

10.     REVIEW AND REVOCATION PERIOD; EFFECTIVE DATE

        Simpson and Wall Data agree that Simpson had up to 21 days to review
this Agreement and consult legal counsel, during which time the proposed terms
of this Agreement were not amended, modified, or revoked by Wall Data ("Review
Period"). Simpson may revoke this Agreement if Simpson so chooses by providing,
within seven days following the date Simpson signs this Agreement ("Revocation
Period"), written notice of Simpson's decision to revoke the Agreement to Wall
Data. This Agreement shall become effective and enforceable upon expiration of
the Revocation Period.

11.     SEVERABILITY

        The provisions of this Agreement are severable, and if any part of it is
found to be unlawful or unenforceable, the other provisions of this Agreement
shall remain fully valid and enforceable to the maximum extent consistent with
applicable law.

12.     GOVERNING LAW

        This Agreement will be governed by the laws of the state of Washington
without regard to its choice of law provisions.

13.     KNOWING AND VOLUNTARY AGREEMENT

        Simpson represents and agrees that Simpson has read this Agreement,
understands its terms and the fact that it releases any claim he might have
against Wall Data and its agents,

                                      -7-

<PAGE>   8




understands that he has the right to consult counsel of choice and has done so,
and enters into this Agreement without duress or coercion from any source.

14.     NONDISPARAGEMENT

        Both Wall Data and Simpson agree that Simpson and Wall Data will not
make or publish, either orally or in writing, any disparaging statements
regarding the other.

15.     ENTIRE AGREEMENT

        This Agreement sets forth the entire understanding between Simpson and
Wall Data and supersedes any prior agreements or understandings, express or
implied, pertaining to the terms of Simpson's employment or board service with
Wall Data and the termination of same, unless expressly reaffirmed and
incorporated herein by reference. Simpson acknowledges that in executing this
Agreement, Simpson does not rely upon any representation or statement by any
representative of Wall Data concerning the subject matter of this Agreement,
except as expressly set forth in the text of the Agreement.

        IN WITNESS WHEREOF, the parties have executed this Agreement as of the
dates indicated below.

                CONFIDENTIAL INFORMATION AND INVENTIONS AGREEMENT

        In consideration of my employment as an employee or independent
contractor with Wall Data Incorporated, a Washington corporation (the

the compensation paid to me by the Company, the understandings set forth below,
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, I agree as follows:

me during the Term, whether solely or jointly with others, and whether or not

or anyone else without the prior written consent of the Company.

        NOTICE: Notwithstanding any other provision of this Agreement to the
contrary, this Agreement does not obligate me to assign or offer to assign to
the Company any of my rights in an invention for which no equipment, supplies,
facilities or trade secret information of the Company was used and which was
developed entirely on my own time, unless (a) the invention relates (i) directly
to the business of the Company or (ii) to the Company's actual or demonstrably
anticipated research or development, or (b) the invention results from any work
performed by me for the Company. This satisfies the written notice and other
requirements of RCW 49.44.140.

SECTION 3.     NO CONFLICTING OBLIGATIONS

        3.1 My execution, delivery and performance of this Agreement and the
performance of my other obligations and duties to the Company will not violate
any other employment, nondisclosure, confidentiality, consulting or other
agreement to which I am a party or by which I may be bound.

        3.2 I will not use in performance of my work for the Company or disclose
to the Company any trade secret, confidential or proprietary information of any
prior employer or other Person if and to the extent that such use or disclosure
may violate any obligation or duty that I owe to such other Person (e.g., under
any agreement or applicable law). My compliance with this paragraph will not
prohibit, restrict or impair the performance of my work, obligations and duties
to the Company.

SECTION 4.     DEDUCTIONS FROM WAGES

        4.1 I hereby authorize and specifically agree to allow the Company to
deduct from my wages the value of any equipment, goods, or other items provided
to me by the Company during my employment which I fail to return when requested
to do so by the Company, provided that such deduction (1) does not exceed the
cost of the item, (2) does not reduce my wages below minimum wage or overtime
compensation below time and a half, (3) is not made for normal wear and tear on
the provided item(s), and (4) is accompanied with a list of all items for which
deductions are being made.

        4.2 I hereby authorize and specifically agree to allow the Company to
deduct from my wages amounts equivalent to any cash shortages, breakage, or loss
of equipment due to my dishonesty, willful act, or gross negligence.

SECTION 5.     EMPLOYMENT AT WILL

        5.1 I agree that my employment is "at will" which means that it can be
terminated at any time by Wall Data, with or without cause and with or without
notice. I agree that any promise or obligation that my employment be on any
other basis than "at will" is invalid unless in writing signed by the Chief
Executive Officer of Wall Data. I agree to abide by the Company's rules,
regulations, policies and practices as revised from time to time.

SECTION 6.     MISCELLANEOUS

        6.1 This Agreement is not a contract of employment for a specified term
or for any length, and no rights of employment are hereby created. My
obligations under this Agreement will survive any termination of my employment.

        6.2 I acknowledge that my obligations under this Agreement are important
to the Company, and that the Company would not employ me without my agreement to
such obligations. I also acknowledge that if I do not abide by my obligations in
this

<PAGE>   13




Agreement in any way, the Company will suffer immediate and irreparable harm,
and that the damage to the Company will be difficult to measure and financial
relief will be incomplete. Accordingly, I agree that in the event of any breach
or default under this Agreement by me, the Company will be entitled to
injunctive relief, specific performance, and other equitable relief. I expressly
waive any defenses to such relief based on whether irreparable harm has occurred
and whether there is an adequate remedy at law. The rights and remedies of the
Company under this paragraph are in addition to, and not in lieu of, any other
right or remedy afforded to the Company under any other provision of this
Agreement, by law or otherwise. Further, if the Company brings an action against
me to enforce its rights under this Agreement or to seek damages for my breach,
and if the Company obtains any relief in such action, I will pay the Company's
attorneys' fees and costs in such action.

        6.3 This Agreement will be enforced to the fullest extent permitted by
applicable law. If for any reason any provision of this Agreement is held to be
invalid or unenforceable to any extent then (a) such provision will be
interpreted, construed or reformed to the extent reasonably required to render
the same valid, enforceable and consistent with the original intent underlying
such provision, and (b) such invalidity or unenforceability will not affect any
other provision of this Agreement or any other agreement between the Company and
me. If the invalidity or unenforceability is due to the unreasonableness of the
scope or duration of the provision, the provision will remain effective for such
scope and duration as may be determined to be reasonable.

        6.4 The failure of the Company to insist upon or enforce strict
performance of any other provisions of this Agreement or to exercise any of its
rights or remedies under this Agreement will not be construed as a waiver or a
relinquishment to any extent of the Company's rights to assert or rely on any
such provision, right or remedy in that or any instance; rather, the same will
be and remain in full force and effect.

        6.5 This Agreement sets forth the entire Agreement, and supersedes any
and all prior agreements, between me and the Company with regard to the
Confidential Information, Inventions, Materials, Proprietary Rights and other
matters of the Company. This Agreement may not be amended, except by writing
signed by the party against whom such amendment is sought to be enforced.

        6.6 The waiver by the Company of any breach of this Agreement by me
shall not be effective unless in writing, and no such waiver shall operate or be
construed as a waiver of the same or another breach on a subsequent occasion.

        6.7 This Agreement will be governed by the laws of the State of
Washington without regard to its choice of law provisions. I irrevocably consent
to the jurisdiction of the courts of the State of Washington, King County, the
United States District Court for the Western District of Washington at Seattle,
and all applicable appellate courts, in connection with any action relating to
this Agreement. Further, I will not bring any action relating to this Agreement
other than in the court specified in this paragraph.

        6.8 I have carefully read all of the provisions of this Agreement and
agree that (a) the same are necessary for the reasonable and proper protection
of the Company's business, (b) the Company has been induced to enter into and
continue its relationship with me in reliance upon my compliance with the
provision of this Agreement, (c) every provision of this Agreement is reasonable
with respect to its scope and duration, and (d) I have received a copy of this
Agreement.

                   ARTICLE II. INFORMATION TECHNOLOGY SERVICES
                             TO BE PERFORMED BY EDS

2.1        EDS Personnel and Management.

           (a)       EDS Account Director. During the Term, EDS will provide an
                     EDS Account Director (the "EDS Account Director") who has
                     the responsibility for the provision of information
                     technology services to be provided by EDS under this
                     Agreement. The EDS Account Director will maintain
                     appropriate work space in the Wall Data facility located at
                     11332 N.E. 122nd Way, Kirkland, Washington 98034-6931, will
                     have overall responsibility for managing and coordinating
                     the delivery of the Services and for the performance of the
                     EDS personnel comprising the EDS/Wall Data account team and
                     will coordinate and consult with the Wall Data
                     Representative (as defined in Section 3.1(a)). The
                     EDS Account Director will meet regularly with the Wall Data
                     Representative as well as other Wall Data designated
                     personnel in order to review the information technology
                     priorities established by Wall Data and the status of EDS'
                     performance under this Agreement. If either Wall Data or
                     EDS desires to replace the EDS Account Director, Wall Data
                     shall have the right (i) to participate in the interview
                     process for the replacement and (ii) to accept or reject
                     the replacement; provided, however, that Wall Data's
                     acceptance must not be unreasonably withheld and any
                     rejection must be for reasonable cause.

           (b)       Steering Committee. On or before the Effective Date, Wall
                     Data and EDS will each give the other written notice of the
                     names of the three members of their respective management
                     staff (inclusive of the EDS Account Director and the Wall
                     Data Representative) who will serve on an executive
                     steering committee (the "Executive Steering Committee").
                     Wall Data will designate one of its members on the



                                       2
<PAGE>   4

                     Executive Steering Committee to act as the chairman of the
                     Executive Steering Committee. The Executive Steering
                     Committee will be responsible for making strategic
                     decisions for Wall Data with respect to linking Wall Data's
                     business objectives to Wall Data's existing and future
                     plans for information technology. Wall Data and EDS each
                     may from time-to-time replace the members of its management
                     staff serving on the Executive Steering Committee with
                     other members of its management staff, except that the EDS
                     Account Director and the Wall Data Representative will be
                     members of the Executive Steering Committee throughout the
                     Term of this Agreement. Although the EDS Account Director
                     will remain a member of the Executive Steering Committee,
                     EDS will remove and replace either of the other two EDS
                     members, which Wall Data, in good faith, requests to have
                     removed for reasonable cause. Wall Data shall have the
                     right (i) to participate in the selection process for the
                     replacement(s) and (ii) to accept the replacement(s),
                     provided, that Wall Data's acceptance is not unreasonably
                     withheld. Wall Data and EDS may mutually agree to increase
                     or decrease the size of the Executive Steering Committee or
                     to change the qualifications of who may serve on the
                     Executive Steering Committee. The Executive Steering
                     Committee will meet at least quarterly unless otherwise
                     agreed by Wall Data and EDS.

           (c)       Transition of Personnel; Notification of Change in
                     Employment Status. On or prior to the Effective Date, EDS
                     will offer employment, effective the start of business on
                     the Effective Date, to the data processing employees of
                     Wall Data identified in Schedule 2.1(c) (the "Transitioned
                     Employees") in accordance with EDS' normal employment
                     policies. In preparation for the transition of employment,
                     EDS and Wall Data will take the necessary measures so that
                     the representatives of the affected personnel departments
                     of the parties will meet and work together to accomplish a
                     smooth and orderly transition for such employees. Neither
                     party will make any representation, promise, or other
                     communication, whether written or oral, to the Transitioned
                     Employees regarding employment with EDS, or the employment
                     benefits, plans, or practices of EDS without obtaining the
                     prior written consent of the other. EDS will notify Wall
                     Data any changes in the employment status of the
                     Transitioned Employees while employed by EDS, including the
                     placement of a Transitioned Employee to an EDS account
                     other than Wall Data.

           (d)       Financial Responsibility for EDS Personnel. Except for
                     out-of-pocket expenses, which shall be paid in accordance
                     with Section 7.1(c), EDS will pay for all personnel
                     expenses, including wages and benefits of its employees
                     performing the Services.

2.2        EDS Information Technology Services.

           (a)       Description of Services. During the Term, and in accordance
                     with the provisions of this Agreement, EDS will provide to
                     Wall Data (a) the services described in the statement of
                     work attached as Schedule 2.2 to this Agreement (the
                     "Statement of Work") and (b) the Networking and
                     Telecommunication Services (defined below). The services
                     described in the Statement of Work and the Networking and
                     Telecommunication Services will be collectively referred to
                     herein as the "Base Services." The Base Services will be
                     performed at the Wall Data facility located at 11332 N.E.
                     122nd Way, Kirkland, Washington 98034-6931, and the Wall
                     Data facilities specifically listed in Schedule 2.2, as
                     such facilities exist as of the Effective Date
                     (collectively, the "Wall Data Locations"). At Wall Data's
                     request, EDS will provide the Base Services at sites other
                     than the Wall Data Locations as an Additional Service in
                     accordance with Section 2.4. The Networking and
                     Telecommunication Services are more particularly described
                     in Section 2.3 below.

           (b)       Service Levels. Wall Data agrees that, during a one hundred
                     eighty (180) day period commencing on the Effective Date
                     and ending on the one hundred eightieth (180th) day
                     thereafter (the "Due Diligence Period"), it will work with
                     EDS to define and determine (i) as of the Effective Date,
                     the existence, use and capacity of the Wall Data Software,
                     the Wall Data-Vendor Software, the Wall Data-Owned
                     Equipment and the Wall Data Leased Equipment that will be
                     used and operated by EDS in the performance of the Base
                     Services, (ii) the manner of measurement, and (iii) the
                     actual respective levels of service pursuant to which the
                     Base Services will be provided by EDS pursuant to this
                     Agreement, which service levels will based on industry
                     standards and the existence, use and capacity of the Wall
                     Data Software, the Wall Data-Vendor Software, the Wall
                     Data-Owned Equipment, the Wall Data Leased Equipment and
                     the Wall Data network as of the Effective Date. After the
                     determination of such service levels, Wall Data will
                     confirm the accuracy of each and, upon such confirmation,
                     approve each such level in writing and deliver such written
                     approval to EDS (the "Service Level Agreement"). The
                     measurements contained in the Service Level Agreement (as
                     may be amended from time to time in accordance with this
                     Section) will be used in each and every instance in which
                     the terms of this Agreement call for, use or refer to, the
                     levels of service for the Base Services to be performed and
                     provided by EDS pursuant to this Agreement.

                     At least annually, the Executive Steering Committee will
                     review the Service Level Agreement and focus on, if
                     applicable, Wall Data's reasonable business requirements,
                     including its desire for any increase in service levels and
                     related capacity requirements, for the subsequent year, and
                     any EDS recommendations stemming from the technology
                     refresh programs described in the Statement of Work. If
                     such review indicates (i) that the service levels contained
                     in the Service Level Agreement need to be adjusted to meet
                     such business requirements, and EDS determines in its
                     reasonable business judgment that, in order to meet such




                                       4
<PAGE>   6

                     adjusted service levels, additional hardware, Software,
                     data/telecommunications services or other items are needed
                     (either as additions to, or replacements of, certain items
                     within Wall Data's then existing information technology
                     environment), or (ii) that technology refreshes in the form
                     of upgrades or otherwise in hardware, Software or other
                     items would be appropriate or desirable, then Wall Data
                     will determine whether it desires to acquire such
                     additional items at its expense as provided below. To the
                     extent that such additional items are so acquired, the
                     parties will mutually determine and agree on appropriate
                     adjustments to the applicable service levels, and such
                     adjustments will be documented in an amendment to the then
                     current Service Level Agreement.

                     In addition, if and to the extent that EDS can demonstrate
                     to the reasonable satisfaction of Wall Data that the then
                     current service levels will, within a period of time
                     reasonably estimated by EDS, no longer be achievable due to
                     the fact that certain hardware, Software or other items
                     material to the operation of Wall Data's then existing
                     information technology environment are (i) obsolete, (ii)
                     worn out, (iii) incompatible with any upgraded technology
                     in use at Wall Data, (iv) no longer commercially supported
                     by the applicable vendor, or (v) not reasonably sufficient
                     to support Wall Data's increased business requirements,
                     then Wall Data will determine whether it desires to replace
                     such items at its expense as provided below. If Wall Data
                     decides not to replace such items, EDS will not be in
                     default of the applicable service level obligations under
                     this Agreement to the extent that such decision adversely
                     affects EDS' ability to properly perform such obligations.

                     Wall Data will be financially responsible for (i) all
                     hardware, Software, equipment, supplies and
                     data/telecommunications services determined to be necessary
                     or desirable in accordance with this Section, and (ii) any
                     service requirements resulting therefrom beyond the scope
                     of services set forth in the Statement of Work, which will
                     be provided by EDS as an Additional Service.

                     The parties agree and acknowledge that, during the period
                     of time in which the measurement activities are to be
                     undertaken pursuant to this Section 2.2(b), EDS will be
                     providing the Base Services pursuant to the terms of this
                     Agreement in a manner so that the delivery of such Base
                     Services reasonably approaches service levels generally
                     recognized within the industry and Wall Data will be
                     obligated to pay EDS for such Base Services during that
                     period.

           (c)       Global Services. The parties acknowledge and agree that
                     this Agreement is intended to be a global agreement and
                     that, for any Services to be performed by EDS for Wall Data
                     outside of the United States, such Services will be
                     performed pursuant to local country agreements or Task
                     Orders, as defined in Section 2.4 below, which will be job
                     specific and country specific for those Services in the
                     country or region in which they are to be performed. In
                     performing Services in countries other than the United
                     States, Wall Data acknowledges and agrees that EDS may
                     perform such Services by or through subsidiaries or
                     affiliates of EDS which are situated in that country or
                     region; 



                                       5
<PAGE>   7

                     provided, however, that EDS and Wall Data will be and
                     remain liable and responsible for their respective
                     obligations under this Agreement and any local country
                     agreements or Task Orders, including the Services being
                     performed and for the payment therefor. Any local country
                     agreement or Task Order, the subject of which is the
                     performance of Services outside of the United States, must
                     be approved in writing by the joint executions of the EDS
                     Account Director and the Wall Data Representative.

           (d)       Export Compliance. This Agreement is expressly made subject
                     to any United States of America government laws,
                     regulations, orders or other restrictions regarding export
                     from the United States of computer hardware, software,
                     technical data or derivatives of such software, hardware or
                     technical data. Notwithstanding anything else in this
                     Agreement to the contrary, neither Wall Data nor EDS shall
                     directly or indirectly export (or re-export) any computer
                     hardware, software, or technical data related to the
                     Services provided pursuant to this Agreement or derivatives
                     of such software, hardware or technical data, or permit
                     shipment of same (i) into (or to a national or resident of)
                     Cuba, North Korea, Iran, Iraq, Libya, Syria, or any other
                     country to which the United States has embargoed goods, or
                     (ii) to anyone on the U.S. Treasury Department's List of
                     Specially Designated Nationals, List of Specially
                     Designated Terrorists and List of Specially Designated
                     Narcotics Traffickers, or the U.S. Commerce Department's
                     Denied Parties List, or (iii) to any country or destination
                     for which the United States government or a United States
                     governmental agency requires as export license or other
                     approval for export without first having obtained such
                     license or other approval. This obligation shall survive
                     the expiration or early termination of this Agreement.

           (e)       Year 2000 Issues. Wall Data acknowledges and agrees that
                     the Base Services do not include any changes,
                     modifications, updates or enhancements to Wall Data
                     Software or any third-party Software which may be necessary
                     so that all of such Software will (i) operate and produce
                     data on and after January 1, 2000 (including taking into
                     effect that such year is a leap year), accurately and
                     without delay, interruption or error relating to the fact
                     that the time at which and the date on which such product
                     is operating is on or after 12:00 a.m. on January 1, 2000
                     (including taking into effect that such year is a leap
                     year) or (ii) accept, calculate, process, maintain, store
                     and output, accurately and without delay, interruption or
                     error, all times or dates, or both, whether before, on or
                     after 12:00 a.m. January 1, 2000 (including taking into
                     effect that such year is a leap year), and any time periods
                     determined or to be determined based on any such times or
                     dates, or both. However, EDS would be willing to provide as
                     an Additional Service for an additional charge all such
                     changes, modifications, updates or enhancements to such
                     Software.

2.3        Networking and Telecommunications Services. During the Term, EDS will
           provide to Wall Data the following services in accordance with the
           responsibilities and assumptions set forth in this Agreement:


                                       6
<PAGE>   8

           (a)       Networking and Telecommunications Services. EDS will
                     acquire, implement and administratively support, on Wall
                     Data's behalf and at Wall Data's expense and with Wall
                     Data's prior written consent to any and all specific
                     services, outbound long distance calling services, 800
                     inbound services and calling card services and any other
                     telecommunications services in place for Wall Data as of
                     the Effective Date to the extent such services are more
                     particularly described in Sections IV and V of the
                     Statement of Work (the "Networking and Telecommunication
                     Services"). EDS may acquire such services from a
                     telecommunications vendor or vendors as EDS deems
                     appropriate (collectively, the "Vendor") and pass those
                     services on to Wall Data as Services under this Agreement.
                     EDS will provide Wall Data with prior notice of its intent
                     to change Wall Data's existing or future Vendor and will
                     not effect a change in Wall Data's existing or future
                     Vendor that would cause Wall Data to incur increased
                     telecommunication rates or charges for the Networking and
                     Telecommunication Services (excluding increased rates and
                     charges based on Wall Data's usage or business
                     requirements) without Wall Data's prior written consent.

                     EDS will provide such Networking and Telecommunication
                     Services to the Wall Data sites identified in Sections IV
                     and V of the Statement of Work. Section IV (Network
                     Management) and Section V (Telecommunications) of the
                     Statement of Work define the scope of the Networking and
                     Telecommunications Services to be provided by EDS as Base
                     Services under this Agreement. In the event there are
                     substantial technological advances in telecommunications or
                     other related media and, as a result of such advances,
                     complexities are introduced that impact or modify the
                     service levels or functions from those in effect as of the
                     Effective Date with regard to the telecommunications
                     responsibilities of EDS, the parties will negotiate in good
                     faith as to any modifications that should be made in this
                     Agreement as a result thereof.

           (b)       Billing Administration. EDS will provide to Wall Data on a
                     monthly basis, a consolidated bill of rated call detail
                     containing the following information: date and time of
                     call, duration, destination (both number and location), and
                     total per Wall Data Location.

           (c)       Implementation Plan. EDS will develop and coordinate with
                     Wall Data and Vendor(s) an implementation plan so as to
                     commence the Networking and Telecommunication Services by
                     July 1, 1997.

           (d)       Quality, Performance and Remedies. EDS makes no
                     representation or warranty respecting the quality of the
                     Networking and Telecommunication Services made available to
                     it by the Vendor or LEC (as defined in Section 7.1(b)(i) of
                     this Agreement) and provided or made available to Wall Data
                     pursuant to this Agreement. Wall Data's remedies for any
                     service problems with respect to the Networking and
                     Telecommunication Services will be the remedies set forth
                     in the tariff, regulations or agreement applicable to such
                     Vendor or LEC. EDS' responsibility will be to coordinate
                     with Wall Data and communicate with the Vendor or LEC and
                     assist Wall 



                                       7

                     Data in the proper reporting of the service problem on Wall
                     Data's behalf and passing through to Wall Data any credits
                     received from such Vendor for such service problem.

2.4        Additional Services. Upon the reasonable written request of Wall
           Data, EDS will, subject to the other terms and conditions of this
           Section 2.4, provide Wall Data with such additional services which
           are beyond the scope, level or capacity of the Base Services
           described in this Agreement as Wall Data and EDS agree in accordance
           with this Section (collectively, the "Additional Services"). The
           specific request for Additional Services to be supplied by EDS to
           Wall Data, the compensation to be paid and other related matters
           shall be expressed in written task orders ("Task Orders") prepared
           from time to time by EDS in response to a request by Wall Data for
           Additional Services. Each Task Order will incorporate by reference,
           and shall be subject to, the terms and conditions of this Agreement.
           EDS acknowledges and agrees that no billable Additional Services
           shall begin unless and until a Task Order is executed and delivered
           by the EDS Account Director and the Wall Data Representative. Each
           Task Order shall be in such form as the parties mutually agree and
           shall contain the following information, as applicable:

           (a)       The incorporation, by reference, of this Agreement.

           (b)       The designation of a unique identifying number.

           (c)       A description of the services or deliverables to be
                     provided by each party, including any documentation or
                     training to be provided by each party.

           (d)       A description of any standards or constraints to be applied
                     to the services performed by EDS.

           (e)       A description of the consideration and terms of payment for
                     services or deliverables.

           (f)       A description of any items of expense authorized for
                     reimbursement to EDS and the basis for such reimbursement.

           (g)       A description of requirements for the delivery and
                     frequency of status reports.

           (h)       The name and telephone number of the Wall Data
                     Representative and the EDS Account Director.

           (i)       A description of the respective Wall Data responsibilities
                     and EDS responsibilities.

           (a)       Wall Data Representative. During the Term, Wall Data will
                     maintain a designated representative (the "Wall Data
                     Representative") who will be a senior executive of Wall
                     Data and who will be authorized to act as the primary point
                     of contact for EDS in dealing with Wall Data with respect
                     to each party's obligations under this Agreement.

           (b)       Transitioned Employees. Wall Data will cooperate with EDS
                     in the performance by EDS of its obligations to offer
                     employment to and hire the Transitioned Employees. Wall
                     Data has not and will not make any representation, promise,
                     or other communication, whether written or oral, to the
                     Transitioned Employees regarding employment with EDS, or
                     the employment benefits, plans, or practices of EDS without
                     obtaining the prior written consent of EDS. Wall Data will
                     direct any such questions to the EDS Account Director.
                     Should EDS request that Wall Data continue to make payments
                     to such employees after they are hired by EDS, Wall Data
                     will do so as an administrative convenience until such
                     personnel can be integrated into the EDS payroll system. In
                     such event, Wall Data will be acting solely as an
                     accommodation to EDS and EDS will reimburse Wall Data for
                     all wages paid and employer's contributions made by Wall
                     Data in connection therewith.

           (c)       Bonus. EDS will pay each Transitioned Employee employed by
                     EDS on July 4, 1997 a bonus of $2,000 within thirty (30)
                     days after such date. Prior to EDS' obligation to pay such
                     bonuses, Wall Data will pay EDS a lump sum aggregate amount
                     equal to $2,000 per Transitioned Employee employed by EDS
                     on July 4, 1997.

3.2        Wall Data Operational Obligations. During the Term, Wall Data will,
           on a timely basis and at no charge to EDS, perform the support
           services and discharge the obligations described in Schedule 3.2.

3.3        Wall Data Financial Obligations. In addition to the payment of
           certain out-of-pocket expenses provided in Section 7.1(c), Wall Data
           shall pay all costs for the acquisition of, or costs associated with,
           any and all Software (including, without limitation, the Wall Data
           Software and the Wall Data-Vendor Software), and hardware (including,
           without limitation, the Wall Data-Owned Equipment and the Wall Data
           Leased Equipment) related to or which may be necessary (as determined
           by the Executive Steering Committee and approved by Wall Data in
           accordance with Section 2.2(b)) for the performance of the Services
           by EDS pursuant to this Agreement, it being hereby acknowledged by
           the parties that such items are not being assigned to, or being
           assumed by, EDS, but shall remain or be the financial
           responsibilities of Wall Data. In addition to any other financial
           responsibilities of Wall Data expressly provided herein, Wall Data
           will pay all costs and expenses related to each item which is to be
           provided by Wall Data pursuant hereto and for which the financial
           responsibility has not been expressly assumed by EDS under this
           Agreement, including, without limitation, the items set forth in
           Sections 3.1 and 3.2.

           maintenance of the Wall Data Software, the Wall Data Vendor Software,
           the Wall Data Owned Equipment and the Wall Data Leased Equipment, and
           EDS agrees to assume all of Wall Data's obligations arising under the
           Maintenance Agreements subsequent to the Effective Date. If a
           required consent is not obtained, then (a) EDS will determine and
           adopt, subject to Wall Data's prior approval, such alternative
           approaches as are necessary and sufficient to perform the Services
           without such required consent, and (b) the parties will mutually
           agree on any appropriate adjustments to this Agreement, including the

           maintenance services is not) in default in any material respect under
           any of the Maintenance Agreements, and (b) it has delivered to EDS
           full and complete copies of the Maintenance Agreements (including any
           amendments thereto) prior to the Effective Date. Wall Data agrees
           that the representations and warranties contained in this Section 4.4
           will be true and correct as of the Effective Date. Wall Data agrees
           that it will not amend any of the Maintenance Agreements prior to the

           deliver an assignment and assumption agreement in a form that is
           mutually agreed to by the parties evidencing the assignment and
           assumption of the Maintenance Agreements contemplated by this
           Section 4.4.

4.5        Further Assurances. Wall Data and EDS agree to execute and deliver
           such other instruments and documents as either party reasonably

           Equipment or the Wall Data Leased Equipment, or (b) amend, modify or
           waive any rights or interests contained in any Wall Data agreement
           relating to the Wall Data-Owned Equipment or the Wall Data Leased
           Equipment, without Wall Data's prior approval.

           OEMs, licensors or other third parties contained in Wall Data's data
           files ("Wall Data's Data") is the exclusive property of Wall Data.

6.2        Confidentiality. Except as otherwise provided in this Agreement, EDS
           and Wall Data each agree that all information communicated to it
           (through its employees, agents, consultants or subcontractors) by the
           other or the other's affiliates, or otherwise obtained through the
           performance of the Services or by reason of physical presence at the
           respective party's facilities (with respect to information the
           recipient should reasonably have known was confidential) whether
           before or after the Effective Date, including, without limitation,
           Wall Data Software, Wall Data's Data, EDS Software, trade secrets,
           proprietary process, and the terms of this Agreement, will be
           received in strict confidence, will be used only for purposes of this
           Agreement, and will not be disclosed by the recipient party, its
           agents, subcontractors or employees without the prior written consent
           of the other party. Each party agrees to use the same means it uses
           to protect its own confidential information, but in any event not
           less than reasonable means, to prevent the disclosure of such
           information to outside parties. However, neither party shall be
           prevented from disclosing information which belongs to such party or
           is (a) already known by the recipient party without an obligation of
           confidentiality other than pursuant to this Agreement; (b) publicly
           known or becomes publicly known through no unauthorized act of the
           recipient party; (c) rightfully received from a third party; (d)
           independently developed without use of the other party's confidential
           information; (e) disclosed without similar restrictions to a third
           party by the party owning the confidential information; (f) approved
           by the other party for disclosure in writing; or (g) required to be
           disclosed pursuant to a requirement of a governmental agency or law
           if the disclosing party provides the other party with notice of this
           requirement prior to disclosure. The provisions of this Section will
           survive the expiration or termination of this Agreement for any
           reason.

6.3        Security. EDS will comply with the security procedures that are in
           effect at the Wall Data Locations as of the Effective Date as made
           known to EDS. EDS will also institute such additional security
           procedures at the Wall Data Locations that Wall Data reasonably
           requests as an Additional Service. Wall Data will provide all
           necessary security personnel and related equipment at the Wall Data
           Locations. Except as to (a) Wall Data's need to access certain
           information including Wall Data's Data for the purposes of Sections
           6.2 and 6.4, and (b) a mutually agreed list of Wall Data employees,
           agents, contractors or invitees, without the prior written consent of
           EDS (such consent not to be unreasonably withheld), no employee,
           agent, contractor or invitee of Wall Data will operate or assist in
           operating equipment or Software to be used by EDS under this
           Agreement in any data center located at the Wall Data Locations or
           any shared EDS data center.

           designates in writing with reasonable access for the limited purpose
           of performing audits or inspections of Wall Data's business. EDS will
           provide reasonable assistance of a routine nature to such auditors
           and inspectors, and EDS will provide additional assistance as an
           Additional Service. EDS will not be required to provide such auditors
           and inspectors access to data of EDS customers, other than Wall Data,
           or proprietary data of EDS.

7.1        Charges for Services

           (a)       Monthly Base Charges.

                     (i)       In consideration for the performance by EDS of
                               the Base Services, for each month following the
                               Effective Date, Wall Data will pay EDS the
                               Monthly Base Charges set forth in Schedule 7.1
                               (the "Monthly Base Charges"), as may be adjusted
                               in accordance with this Article. EDS will invoice
                               each such Monthly Base Charges on the first
                               business day of the month to which it relates and
                               such Monthly Base Charges will be due and payable
                               thirty (30) days after the date of the invoice.
                               The Monthly Base Charges for any partial month
                               will be prorated on a per diem basis. In addition
                               to the payment of the Monthly Base Charges, Wall
                               Data will also make payments for any Additional
                               Services which EDS may be providing to Wall Data
                               pursuant to the terms and conditions of this
                               Agreement.

                     (ii)      The parties agree and acknowledge that, for any
                               of the Services provided by EDS outside of the
                               United States, EDS may invoice and collect such
                               payments in the local currency of the country or
                               region in which such Services were provided.

                     (iii)     In addition to the above, the parties agree that,
                               during each November during the Term (the "Annual
                               Review Meeting"), the parties will meet and
                               jointly review the amount of the Monthly Base
                               Charges (including the Networking and
                               Telecommunication Services charges) for the
                               upcoming year of the Term in comparison to the
                               business plan (as it relates to information
                               technology), the information technology budget of
                               Wall Data, and Wall Data's planned revenue growth
                               rate (as determined by Wall Data's board of
                               directors) for the upcoming year. If such a
                               review reflects that there is a significant
                               disparity between the amount of the Monthly Base
                               Charges for such upcoming year of the Term and
                               the business plan, budgets and planned revenue
                               growth rate of Wall Data, the parties will
                               negotiate in good faith as to the amounts of the
                               Monthly Base Charges for the upcoming year (which
                               may include a proposed change in the usage rates
                               to be charged for the Networking and
                               Telecommunication Services); provided, however,
                               that, if the parties can not agree on such
                               amounts within thirty (30) days after such
                               meeting, the amounts for the Monthly Base Charges
                               will be adjusted in accordance with the
                               calculation set forth in Schedule 7.1.

                               The parties further agree that, during each May
                               during the Term (or at such later date as either
                               party may request), the parties will meet again
                               and jointly review the impact of a Material
                               Growth Change (as defined below), if any, to

                               the Wall Data planned revenue growth rate
                               presented to EDS at the applicable Annual Review
                               Meeting and negotiate in good faith the
                               appropriate adjustments to the Monthly Base
                               Charges based on the Material Growth Change;
                               provided, however, that, if the parties can not
                               agree on such adjustments within thirty (30)
                               days after such meeting, the parties will adjust
                               the Monthly Base Charges in accordance with the
                               calculation set forth in Schedule 7.1. For
                               purposes of this Section 7.1(a)(iii), a
                               "Material Growth Change" shall mean a revision
                               in Wall Data's planned revenue growth rate as
                               adopted in good faith by Wall Data's board of
                               directors.

           (b)       Networking and Telecommunications Services Charges.

                     (i)       Wall Data will pay, in the manner reflected in
                               this Section 7.1(b), to EDS all charges billed
                               pursuant to the billing administration section of
                               the Networking and Telecommunication Services in
                               Section 2.3(b), which shall consist of recurring,
                               non-recurring and usage charges (including
                               applicable billings to the Vendor (as defined in
                               Section 2.3(a)) from the applicable Local
                               Exchange Carriers ("LEC's") but excluding
                               applicable billings to Wall Data from the
                               applicable LECs) and applicable taxes with
                               respect to the services provided or made
                               available to Wall Data under this Agreement. Such
                               charges shall be based upon and subject to EDS'
                               agreement with the Vendor providing such
                               services, including all tariffs, rates, volume
                               commitments, discounts, restrictions, covenants,
                               regulations and other conditions contained
                               therein and applicable thereto from time to time.
                               In addition to any such agreement between EDS and
                               the Vendor and potential changes thereto, as
                               permitted by the Federal Communications
                               Commission and the state utility commissions, the
                               LECs may, from time to time, effect tariff
                               revisions which will change the recurring
                               (access) and intrastate usage charges to EDS.
                               When this occurs, EDS will adjust its charges to
                               Wall Data to reflect such changes and will notify
                               Wall Data as promptly as possible of any such
                               change. In addition, the parties acknowledge that
                               charges to Wall Data for any given month will be
                               based upon Wall Data calling patterns for such
                               month, including originating locations, locations
                               called, frequency of calls, length and time of
                               calls and other such factors, and that such
                               charges may therefore fluctuate accordingly from
                               month to month. The usage rates that will be
                               charged by EDS to Wall Data for the Networking
                               and Telecommunication Services are reflected in
                               Schedule 7.1(b), attached hereto and made part
                               hereof.

                               As to the manner of payment for the Networking
                               and Telecommunication Services provided by EDS,
                               the parties will establish for Wall Data a dollar
                               amount which shall be a baseline (the "Baseline")
                               on Networking and Telecommunication Services
                               usage which shall be based on the average
                               recurring, non-recurring and usage charges
                               incurred by Wall Data in the three (3) months
                               immediately preceding the Effective Date. The
                               Monthly Base Charges paid to EDS will include the
                               Networking and Telecommunications 



                                       15

                               Services Baseline amount. Each calendar quarter
                               during the Term, EDS and Wall Data will have a
                               reconciliation of the Networking and
                               Telecommunication Services payments as to the
                               amounts paid to EDS (based on the Baseline
                               amounts) as compared to the actual usage amounts
                               (both as to actual usage greater than and less
                               than the Baseline). Due to the information that
                               will be available at the time of the
                               reconciliation, such reconciliation will be for
                               the last month of the immediately prior calendar
                               quarter and the first two (2) months of the
                               calendar quarter which would have just concluded
                               prior to the reconciliation. The parties agree
                               and acknowledge that Wall Data shall ultimately
                               be responsible and liable to pay only for its
                               actual usage of the Networking and
                               Telecommunication Services. On an annual basis,
                               the parties will negotiate in good faith to
                               adjust the amount of the Baseline as it compares
                               to the charges then in effect.

                     (ii)      Certain LEC Charges. The LECs providing
                               Networking and Telecommunication Services to Wall
                               Data under this Agreement may require
                               non-recurring installation charges for
                               implementation of such Services. Such charges, if
                               billed to EDS, will be passed directly through to
                               Wall Data at the amount charged to EDS by the
                               LECs. Should Wall Data choose to provide access
                               to the Networking and Telecommunication Services
                               through its LEC rather than through the Vendor,
                               Wall Data shall be responsible for coordinating
                               with such LEC and assuring such LEC's
                               coordination with the Vendor for implementation
                               and support of such access, and for any recurring
                               or non-recurring charges associated with such
                               access, whether such charges are billed to Wall
                               Data or EDS.

                               (iii) Pre-Service Conversion Date Charges. For
                               any conversions that may need to occur for EDS to
                               provide the Networking and Telecommunication
                               Services, if any, for each Wall Data Location,
                               Wall Data will retain all financial
                               responsibility for voice telecommunications
                               services for the period prior to the date that
                               the Vendor or LEC converts the Networking and
                               Telecommunication Services (the "Service
                               Conversion Date"), whether the charges for such
                               services are received by Wall Data or EDS either
                               prior to or following the Service Conversion
                               Date.

                               (iv) Taxes. There will be added to any charges
                               hereunder, if applicable, and Wall Data shall pay
                               to EDS, amounts equal to any taxes, however
                               designated or levied, based upon such charges, or
                               upon this Agreement and Networking and
                               Telecommunication Services or Telecommunications
                               Equipment provided hereunder, or their use,
                               including state and local sales, use, privilege
                               or excise taxes based on gross revenue, and any
                               taxes or amounts in lieu thereof paid or payable
                               by EDS in respect of the foregoing, exclusive,
                               however, of franchise taxes, taxes based on net
                               income of EDS and taxes incurred by EDS pursuant
                               to the Washington business and occupations tax
                               law.

                               Should Additional Services be required by Wall
                               Data which change the scope of the Networking and
                               Telecommunication Services offered pursuant to
                               this Agreement, Section 2.4 of the Agreement will
                               apply. Unless otherwise stated in this Section
                               7.1(b), all payments shall be made in accordance
                               with Article VII of this Agreement.

           (c)       Out-of-Pocket Expenses. In addition to the payment of the
                     Monthly Base Charges or the fees for any Additional
                     Services, Wall Data will pay for all reasonable
                     out-of-pocket expenses that Wall Data has given prior
                     written authorization. Such out-of-pocket expenses include,
                     without limitation, travel and travel-related expenses that
                     are directly related to the provision by EDS of the
                     Services.

           (d)       Adjustment for Significant Business Changes. If, during the
                     Term, Wall Data, (i) is merged into another entity or
                     another entity is merged into Wall Data, (ii) is sold to or
                     purchased by another entity or Wall Data buys or purchases
                     another entity, (iii) experiences a change from its
                     operations which results in a substantial change in its
                     financial standing or net worth as of the Effective Date,
                     or (iv) experiences any other type of business modification
                     which results in a substantial change in Wall Data's need
                     for the quantity or quality of the Services to be provided
                     by EDS pursuant to the terms of this Agreement, then, in
                     any of such events, upon written request of either party to
                     this Agreement, the parties will negotiate in good faith to
                     reach a mutually agreeable adjustment in the amount of the
                     payments to made by Wall Data to EDS and any other related
                     provisions to this Agreement as may be necessary or desired
                     as a result of the events stated above. Except as provided
                     in Section 9.5, in no event will this Section 7.1(d) be
                     grounds for termination of this Agreement unless the
                     parties mutually agree to so terminate this Agreement for
                     such a significant business change.

7.2        Cost of Living Adjustment.

           (a)       Adjustment. Except with respect to the period commencing on
                     the Effective Date and ending on November 1, 1997, if the
                     Consumer Price Index for all Urban Consumers, U.S. City
                     Average, for All Items (1982-84 = 100), as published in the
                     Bureau of Labor Statistics of the Department of Labor (the
                     "CPI"), shall on November 1st of each year during the Term,
                     commencing with November 1, 1998, (the "Current Index") be
                     higher or lower than the CPI at the previous November 1st
                     (such CPI, the "Base Index"), then, effective as of the
                     following January 1st, all charges for Services under this
                     Agreement attributable to the period following such January
                     1st (other than charges based upon then current EDS rates

                     Services), as previously adjusted pursuant to this Section,
                     shall be increased by [*] of the percentage that the
                     Current Index increased from the Base Index. With respect
                     to the period commencing on the Effective Date and ending
                     on November 1, 1997, if the CPI shall on November 1, 1997
                     (the "November Index") be higher or lower than the CPI as
                     of the Effective Date (the "May Index"), then, effective as
                     of January 1, 1998, all charges for Services under this
                     Agreement attributable to the period following such January

                     rates and the rates for the Networking and
                     Telecommunication Services), shall be increased by [*] of
                     the percentage that the November Index increased from the
                     May Index.

           (b)       Change of Index. In the event that the Bureau of Labor
                     Statistics should stop publishing the CPI or should
                     substantially change the content or format thereof, the
                     parties hereto shall substitute therefor another comparable
                     measure published by a mutually acceptable source;
                     provided, however, that if such change is merely to
                     redefine the base year for the CPI from 1982-84 to some
                     other year, the parties shall continue to use the CPI, but
                     shall, if necessary, convert either the Base Index or the
                     Current Index to the same basis as the other by multiplying
                     such index by the appropriate conversion factor.

           (c)       Foreign Countries. The parties agree that for any
                     Additional Services performed in countries other than the
                     United States, if the compensation for such Additional
                     Services is paid in the local currency, the payments for
                     such Additional Services will be subject to adjustment for
                     the cost of living in such countries using the index in
                     that country that is the most similar to the CPI.

7.3        Time of Payment. Any sum due EDS hereunder for which a time for
           payment is not otherwise specified will be due and payable thirty
           (30) days from the date of the invoice. Any sum due EDS hereunder
           that is not paid when due will thereafter be subject to and bear
           interest until paid at the lesser of (a) the prime rate established
           from time to time by Citibank, New York N.A. plus two percent per
           annum, or (b) the maximum rate of interest allowed by applicable law.

7.4        Taxes. There will be added to any charges for Services hereunder, and
           Wall Data shall pay to EDS, amounts equal to any taxes or
           assessments, however designated or levied, based upon such charges,
           or upon this Agreement or the Software, services or items provided
           hereunder by EDS, or their use, including state and local sales, use,
           privilege or excise taxes based on gross revenue (or any similar
           taxes or assessments in countries other than the United States), and
           any taxes or amounts in lieu thereof paid or payable by EDS in
           respect of the foregoing, exclusive, however, of franchise taxes,
           taxes based on net income of EDS and taxes incurred by EDS pursuant
           to the Washington business and occupations tax law.

7.5        Verification of Costs. The terms set forth in this Agreement are
           based upon information furnished by each of the parties to the other.
           Both parties believe that such information is accurate and complete.
           However, if any such information should prove to be inaccurate or
           incomplete in any material respect, the two parties will negotiate in
           good faith to make appropriate adjustments to the provisions hereof,
           including, without limitation, the charges for Services provided by
           EDS.

7.6        Supporting Documentation. Upon the reasonable request of Wall Data,
           EDS shall make available to Wall Data for review documentation
           appropriate thereto which supports EDS' time and material charges and
           out-of-pocket expenses hereunder.

                        ARTICLE VIII. DISPUTE RESOLUTION

8.1        Annual Quality Review. At least annually, EDS and Wall Data will meet
           to review the performance of their obligations under this Agreement,
           including providing Wall Data with a customer satisfaction survey and
           conducting interviews with Wall Data management personnel by EDS
           personnel. EDS and Wall Data will meet to review the results of each
           quality review and measure continuous service improvement. In
           addition, plans for future information technology activities and work
           schedules will be reviewed by the parties.

8.2        Performance Review. During the course of the long-term relationship
           provided for in this Agreement, disputes, controversies or claims may
           arise between the parties. To minimize the expense to and impact on
           each party of formally resolving such disputes, controversies and
           claims, the EDS Account Director and the Wall Data Representative
           will meet regularly to review the performance of each party of its
           obligations under this Agreement. If the parties are unable to
           resolve a dispute, controversy or claim through this performance
           review process, upon the written request of either party, each party
           will appoint a representative whose task it will be to meet for the
           purpose of resolving the dispute, controversy or claim. Such
           representatives will discuss the dispute, controversy or claim and
           negotiate a resolution in good faith, without the necessity of any
           formal proceeding relating thereto. No formal proceedings for the
           resolution of such dispute, controversy or claim may be commenced
           until either or both of the appointed representatives conclude in
           good faith that amicable resolution through continued negotiation of
           the matter is not likely. Except where clearly prevented by the area
           in dispute, both parties agree to continue performing their
           respective obligations under this Agreement while the dispute is
           being resolved unless and until such obligations are terminated or
           expire in accordance with the provisions hereof.

8.3        Arbitration.

           (a)       Procedures. Any dispute, controversy or claim arising out
                     of or related to this Agreement, or the creation, validity,
                     interpretation, breach or termination of this Agreement,
                     that the parties are unable to resolve through informal
                     discussions or negotiations pursuant to Section 8.2, will
                     be submitted to binding arbitration using the following
                     procedure:

                     (i)         The arbitration will be held in Seattle,
                                 Washington, or wherever both parties may
                                 mutually agree, before a panel of three
                                 arbitrators. Either party may demand
                                 arbitration in writing, by serving on the other
                                 party a statement of the dispute, controversy
                                 or claim, and the facts relating or giving rise
                                 thereto, in reasonable detail, and the name of
                                 the arbitrator selected by it.

                     (ii)        Within 30 days after such demand, the other
                                 party will name its arbitrator, and the two
                                 arbitrators named by the parties will, within
                                 30 days after such demand, select the third
                                 arbitrator.



                                       19
<PAGE>   21

                     (iii)       The arbitration will be governed by the
                                 Commercial Arbitration Rules of the American
                                 Arbitration Association (the "AAA"), except as
                                 expressly provided in this Section. However,
                                 the arbitration will be administered by any
                                 organization mutually agreed upon by the
                                 parties. If the parties are unable to agree
                                 upon the organization to administer the
                                 arbitration, it will be administered by the
                                 AAA. The arbitrators may not amend or disregard
                                 any provision of this Agreement or applicable
                                 law.

                     (iv)        The arbitrators will allow such discovery as is
                                 appropriate to the purposes of arbitration in
                                 accomplishing fair, speedy and cost effective
                                 resolution of disputes. The arbitrators will
                                 reference the rules of evidence of the Federal
                                 Rules of Civil Procedure then in effect in
                                 setting the scope and direction of such
                                 discovery. The arbitrators will not be required
                                 to make findings of fact or render opinions of
                                 law.

                     (v)         The decision of and award rendered by the
                                 arbitrators will be final and binding on the
                                 parties. Judgment on the award may be entered
                                 in and enforced by any court of competent
                                 jurisdiction.

           (b)       Enforcement. Other than those matters involving injunctive
                     relief as a remedy, or any action necessary to enforce the
                     award of the arbitrators, the provisions of this Section
                     are a complete defense to any suit, action or other
                     proceeding instituted in any court or before any
                     administrative tribunal with respect to any dispute,
                     controversy or claim arising out of or related to this
                     Agreement or the creation, validity, interpretation, breach
                     or termination of this Agreement. The provisions of this
                     Section will survive the expiration or termination of this
                     Agreement for any reason. Nothing in this Section prevents
                     the parties from exercising the termination rights set
                     forth in this Agreement.

           (c)       Services during Arbitration. Unless EDS is bringing an
                     action under this Section for nonpayment of undisputed
                     amounts by Wall Data or if Wall Data has failed to place a
                     disputed amount into escrow pursuant to Section 9.2, EDS
                     will continue to provide the Services, and Wall Data shall
                     continue to make payments to EDS in accordance with this
                     Agreement during the arbitration proceedings.

8.4        Sole and Exclusive Venue. SUBJECT TO THE PROVISIONS OF SECTION
           8.3(b), EACH PARTY IRREVOCABLY AGREES THAT ANY LEGAL ACTION, SUIT OR
           PROCEEDING BROUGHT BY IT IN ANY WAY ARISING OUT OF THIS AGREEMENT
           MUST BE BROUGHT SOLELY AND EXCLUSIVELY IN THE UNITED STATES DISTRICT
           COURT FOR THE WESTERN DISTRICT OF WASHINGTON AT SEATTLE OR IN THE
           STATE COURTS OF THE STATE OF WASHINGTON AND EACH PARTY IRREVOCABLY
           ACCEPTS AND SUBMITS TO THE SOLE AND EXCLUSIVE JURISDICTION OF EACH OF
           THE AFORESAID COURTS IN PERSONAM, GENERALLY AND UNCONDITIONALLY WITH
           RESPECT TO ANY ACTION, SUIT OR PROCEEDING BROUGHT BY OR AGAINST IT BY
           THE OTHER PARTY; provided, however that this paragraph shall not

           prevent a party against whom any legal action, suit or proceeding is
           brought by the other party in the state courts of the State of
           Washington from seeking to remove such legal action, suit or
           proceeding, pursuant to applicable Federal law, to the district court
           of the United States for the district and division embracing the
           place where the action is pending in the state courts of the State of
           Washington and in the event an action is so removed, each party
           irrevocably accepts and submits to the jurisdiction of the aforesaid
           district court. Each party hereto further irrevocably submits to the
           service of process required by the State of Washington. EXCEPT AS
           PERMITTED UNDER THE IMMEDIATELY PRECEDING SENTENCE, EACH PARTY HEREBY
           IRREVOCABLY COVENANTS AND AGREES NOT TO BRING ANY LEGAL ACTION, SUIT
           OR PROCEEDING IN ANY WAY ARISING OUT OF THIS AGREEMENT IN ANY OTHER
           COURT OR IN ANY JURISDICTION AND AGREES NOT TO ASSERT ANY CLAIM,
           WHETHER AS AN ORIGINAL ACTION OR AS A COUNTERCLAIM OR OTHERWISE,
           AGAINST THE OTHER IN ANY OTHER COURT OR JURISDICTION. Each party
           hereto hereby irrevocably waives and agrees not to assert, by way of
           motion, as a defense or otherwise, any objection which it may now or
           hereafter have to the laying of venue of any of the aforesaid
           actions, suits or proceedings arising out of or in connection with
           this Agreement brought in the courts referred to above and hereby
           further irrevocably waives and agrees not to plead or claim in any
           such court that any such action or proceeding brought in any such
           court has been brought in an inconvenient forum, that the venue of
           the suit, action or proceeding is improper, or that this Agreement or
           the subject matter hereof or thereof may not be enforced in or by
           such court. As the only exception to any of the above, if a party is
           entitled to seek injunctive or other equitable relief which is not
           available in the venue specified in this Section, this Section shall
           not be deemed to be a bar to the party seeking such relief if such
           relief is wholly non-monetary injunctive or other equitable relief.

                             ARTICLE IX. TERMINATION

9.1        Termination for Cause.

           (a)       Except as provided in Section 9.1(b) and except for a
                     default by Wall Data in its obligation to pay EDS, if
                     either party materially defaults in the performance of any
                     of its obligations under this Agreement, which default
                     shall not be substantially cured within 30 days after
                     written notice is given to the defaulting party specifying
                     the default then, the party not in default, by giving
                     written notice to the defaulting party, may terminate this
                     Agreement as of a date specified in the notice of
                     termination.

           (b)       With respect to a material default which cannot reasonably
                     be cured within 30 days, if the defaulting party fails to
                     immediately (1) proceed to commence curing said default at
                     the beginning of such thirty-day period, (2) proceed with
                     all due diligence to substantially cure that default, and
                     (3) commit the necessary resources as described in Section
                     9.1(d), or if such default is not substantially cured
                     within 120 days after the defaulting party's receipt of
                     written notice specifying the default, then, the party not
                     in default, by giving written notice to the defaulting
                     party, may terminate this Agreement as of a date specified
                     in the notice of termination.



                                       21
<PAGE>   23

           (c)       If either party has repeatedly committed material defaults
                     in the performance of any of its obligations under this
                     Agreement, as described in Sections 9.1(a) and (b), then
                     the party not in default, by giving thirty (30) days
                     written notice to the defaulting party, may terminate this
                     Agreement as of a date specified in the notice of
                     termination.

           (d)       With respect to Sections 9.1(a) and (b), each party agrees
                     that, upon receipt of a default notice under this Section
                     9.1, it will immediately commence all commercially
                     reasonable efforts to resolve or cure the specified default
                     and to commit the resources necessary, at the defaulting
                     party's expense, to resolve or cure the specified default
                     as soon as possible. If EDS is the defaulting party, Wall
                     Data may immediately escalate the alleged default to either
                     the EDS Hi-Tech Manufacturing SBU President or Vice
                     President of Operations for resolution.

9.2        Termination for Nonpayment. If Wall Data defaults in the payment when
           due of any amount due to EDS and does not cure such default within 15
           days after being given written notice of such default, then EDS, by
           giving written notice thereof to Wall Data, may terminate this
           Agreement as of a date specified in such notice of termination
           provided, however, (a) if the nonpayment is [*] or more and is
           the result of a good faith dispute regarding EDS' performance under
           this Agreement, Wall Data may pay amounts claimed to be due into an
           escrow account maintained by a disinterested third party, and in such
           event, Wall Data shall not be in default under this Section 9.2, and
           (b) if the nonpayment is less than [*] and is the result of a
           good faith dispute regarding EDS' performance under this Agreement,
           Wall Data and EDS shall promptly negotiate in good faith to reach a
           settlement to the dispute.

9.3        Termination for Insolvency. Subject to the provisions of Title 11,
           United States Code, if either party becomes or is declared insolvent
           or bankrupt, is the subject of any proceedings relating to its
           liquidation, insolvency or for the appointment of a receiver or
           similar officer for it, makes an assignment for the benefit of all or
           substantially all of its creditors, or enters into an agreement for
           the composition, extension, or readjustment of all or substantially
           all of its obligations, then the other party, by giving written
           notice to such party, may terminate this Agreement as of a date
           specified in such notice of termination.

9.4        Termination for Convenience. On each of the fourth, sixth and eighth
           anniversaries of the Effective Date, Wall Data will have a one-time
           option to terminate this Agreement. Wall Data may exercise its option
           to terminate this Agreement on either (a) the fourth anniversary of
           the Effective Date (the "First Termination Date") by notifying EDS in
           writing of Wall Data's intention to terminate this Agreement at least
           nine (9) months prior to such fourth anniversary, (b) the sixth
           anniversary of the Effective Date (the "Second Termination Date") by
           notifying EDS in writing of Wall Data's intention to terminate this
           Agreement at least nine (9) months prior to such sixth anniversary;
           or (c) the eighth anniversary of the Effective Date (the "Third
           Termination Date") by notifying EDS in writing of Wall Data's
           intention to terminate this Agreement at least nine (9) months prior
           to such eighth anniversary; provided that (i) Wall Data is not then
           and does not become in default under any of the terms of this
           Agreement prior to the First Termination Date, the

           Second Termination Date, or the Third Termination Date, as
           applicable, (and any such default is not timely cured), and (ii) on
           or before the First Termination Date, the Second Termination Date, or
           the Third Termination Date, as applicable, Wall Data pays to EDS the
           termination fee as described in the following table (the "Termination
           Fee").

             Fourth Year Option     The Termination Fee shall be an amount
                                    equal to the sum of (i) the [*] for
                                    [*] rendered [*] immediately preceding the
                                    [*] and (ii) the [*] (as defined below).

             Sixth Year Option      The Termination Fee shall be an amount
                                    equal to the sum of (i) the [*] for
                                    [*] rendered [*] immediately preceding the
                                    [*], and (ii) the [*].

             Eighth Year Option     The Termination Fee shall be an amount
                                    equal to the sum of (i) the [*] for
                                    [*] rendered [*] immediately preceding the
                                    [*], and (ii) the [*].

           The term "Hardware Charges" shall mean any amounts related to the
           purchase or lease by EDS of hardware (with such purchases or leases
           being completed with Wall Data's written consent) to be used to
           provide the Services to Wall Data pursuant to this Agreement;
           provided, however, that such amounts are either the non-depreciated
           amounts on EDS' books for purchased hardware or the outstanding
           amounts due and payable by EDS under the applicable lease for any of
           such hardware. Upon EDS' receipt of payment for such Hardware
           Charges, EDS will either, as applicable, convey title to, or assign
           the lease of, such hardware to Wall Data.

           The parties do not intend that the Termination Fee will be a penalty
           or liquidated damages but that it is consideration for EDS'
           accommodation of Wall Data's desire to have the ability to terminate
           this Agreement prior to the Expiration Date. The parties acknowledge
           and agree that, upon EDS' receipt of the Termination Fee, Wall Data
           will not thereafter be held in default of this Agreement for
           terminating this Agreement prior to the Expiration Date.

9.5        Termination for Change of Control. If at any time after the one year
           anniversary of this Agreement, Wall Data sells all or substantially
           all its assets to an unaffiliated third party or sells a sufficient
           amount of its issued and outstanding stock to an unaffiliated third
           party and such sale effects a change in control (for purposes of this
           Section 9.5, "control" meaning the right to primarily direct and
           manage the operations of Wall Data), then Wall Data may terminate
           this Agreement, by, after reaching an agreement in principle to

           consummate such sale, providing EDS with at least nine (9) months
           prior written notice of Wall Data's intention to terminate this
           Agreement; provided that (a) Wall Data is not then and does not
           become in default under any of the terms of this Agreement prior to
           the termination date as specified in Wall Data's notice (the "Change
           of Control Termination Date"), and any such default is not timely
           cured, and (b) on or before the Change of Control Termination Date,
           Wall Data pays to EDS the "Change of Control Termination Fee"
           calculated as follows: (i) if the sale occurs during [*] through [*]
           of this Agreement (as measured from the Effective Date), the Change
           of Control Termination Fee shall be an amount equal to the [*] during
           the [*] period immediately preceding the Change of Control
           Termination Date, and (2) [*], (ii) if the sale occurs during [*]
           through [*] of this Agreement (as measured from the Effective Date),
           the Change of Control Termination Fee shall be an amount equal to the
           [*] during the [*] period preceding the Change of Control 
           Termination Date, and (2) [*], or (iii) if the sale occurs during 
           [*] of this Agreement (as measured from the Effective Date), the
           Change of Control Termination Fee shall be an amount equal to the 
           [*] during the [*] period immediately preceding the Change of Control
           Termination Date, and (2) [*]. Upon EDS' receipt of payment for such
           Hardware Charges, EDS will either, as applicable, convey title to, or
           assign the lease of, such hardware to Wall Data.

           The parties do not intend that the Change of Control Termination Fee
           will be a penalty or liquidated damages but that it is consideration
           for EDS' accommodation of Wall Data's desire to have the ability to
           terminate this Agreement prior to the Expiration Date. The parties
           acknowledge and agree that, upon EDS' receipt of the Change of
           Control Termination Fee, Wall Data will not thereafter be held in
           default of this Agreement for terminating this Agreement prior to the
           Expiration Date.

9.6        Transition Services upon Termination.

           (a)       Services. In connection with the termination of this
                     Agreement at the Expiration Date or by Wall Data pursuant
                     to Sections 9.1, 9.3, 9.4, 9.5, 11.9(b), or 11.9(c), EDS
                     will contribute, assist and comply with Wall Data's
                     reasonable directions to cause the orderly transition and
                     migration to Wall Data or a third party company to whom
                     Wall Data would be transferring the Services from EDS of
                     all Services then being performed by EDS (the "Termination
                     Transition"). Wall Data, its employees, and agents will
                     cooperate in good faith with EDS in connection with EDS'
                     obligations under this Section and Wall Data will perform
                     its obligations under the Transition Plan (as defined in
                     this Section). EDS will perform the following obligations
                     (and such other obligations as may be contained in the
                     Transition Plan) at Wall Data's expense unless otherwise
                     stated below or as mutually agreed in the Transition Plan.

                     (i)         EDS and Wall Data will work together to develop
                                 a transition plan (the "Transition Plan")
                                 setting forth the respective tasks to be
                                 accomplished by each party in connection with
                                 the orderly transition and a schedule pursuant
                                 to which the tasks are to be completed.

                     (ii)        EDS will provide Wall Data with detailed
                                 specifications for hardware or other equipment
                                 which Wall Data will require to properly
                                 perform the services and procedures previously
                                 performed by EDS.

                     (iii)       Wall Data may purchase from EDS at its net book
                                 value, and subsequently assume the leases
                                 (provided such leases are assumable) for, any
                                 hardware owned or leased by EDS and which is
                                 dedicated to providing the Services to Wall
                                 Data as of the Expiration Date or the effective
                                 date of such termination.

                     (iv)        EDS will deliver to Wall Data and will assist
                                 in the installation on Wall Data's hardware and
                                 equipment the Licensed Programs (as defined in
                                 Section 5.3) which are subject to a mutually
                                 agreeable license agreement

                     (v)         EDS will reasonably assist Wall Data, at Wall
                                 Data's expense, in Wall Data's acquisition of
                                 any necessary rights to access and use any
                                 EDS-Vendor Software and documentation then
                                 being used by EDS in connection with the
                                 processing of Wall Data's information pursuant
                                 to this Agreement.

                     (vi)        EDS will deliver to Wall Data (a) copies of
                                 existing documentation relating to any Wall
                                 Data Software delivered or Licensed Program
                                 licensed to Wall Data pursuant to paragraphs
                                 (iv) and (v) of this Section, and (b) such
                                 documentation for EDS Vendor Software used at
                                 the time of termination of this Agreement by
                                 EDS to provide the Services which is available
                                 to EDS and which EDS is permitted to furnish to
                                 Wall Data.

                     (vii)       EDS will provide appropriate training for the
                                 Wall Data employees who will be assuming
                                 responsibility for operation of the Software
                                 following the Transition Termination.

                     (viii)      Notwithstanding Section 11.7, Wall Data may
                                 offer employment to any EDS employee who is
                                 then dedicated to providing the Services to
                                 Wall Data.

9.7        Regulatory Requirements.  The parties agree as follows:

           (a)       EDS and Wall Data specifically acknowledge and agree that
                     this Agreement and the integrated Networking and
                     Telecommunication Services provided hereunder have been
                     negotiated and uniquely customized and tailored to satisfy
                     the special requirements of Wall Data.

           (b)       The parties further agree that if any Networking and
                     Telecommunication Services provided hereunder are required
                     by a specific decision of applicable regulatory or judicial
                     authority to be provided under tariff, or if a decision by
                     a regulatory authority at the federal, state or local level
                     materially alters or invalidates this Agreement, or any
                     material provision hereof, or if Vendor and/or LEC, in
                     their sole discretion, file a tariff for the Networking and
                     Telecommunication Services provided hereunder, then (i) EDS
                     will have the option to negotiate modifications to this
                     Agreement with Wall Data, or (ii) if the parties cannot
                     reach agreement, after good faith negotiations, as to
                     appropriate modifications to this Agreement resulting from
                     such regulatory requirements, then either party may
                     terminate this Agreement as to the Networking and
                     Telecommunication Services, in whole or in part, and EDS
                     will provide to Wall Data a pro-rata refund for any prepaid
                     charges, subject to any limitations set forth in this
                     Agreement, and Wall Data will pay to EDS any charges (such
                     as any Vendor termination fees) that EDS incurs as a result
                     of the terminated Networking and Telecommunication
                     Services. If any of the Networking and Telecommunication
                     Services are required by a specific decision of any
                     applicable regulatory or judicial authority to be provided
                     under tariff or Vendor and/or LEC file a tariff for the
                     Networking and Telecommunication Services provided
                     hereunder, and either party elects option (ii) above, then
                     the party electing such option shall provide to the other
                     written notice at least thirty (30) days prior to
                     termination.

           (c)       In no event, however, shall EDS have any liability to Wall
                     Data as a result of any regulatory requirements imposed by
                     any agency of the United States government, state or local
                     governments on a Vendor and/or LEC and any independent
                     actions which the Vendor and/or LEC may undertake which
                     alters the terms, conditions and methodology for providing
                     Networking and Telecommunication Services hereunder or
                     renders the provision of such Networking and
                     Telecommunication Services unlawful.

                ARTICLE X. WARRANTIES, INDEMNITIES AND LIABILITY

10.1       Warranty and Disclaimer.

<PAGE>   28

           (a)       In all cases where EDS has not committed to a specific
                     performance standard, EDS will provide the Services in
                     accordance with industry practices and standards generally
                     applicable for such Services at the time the Services are
                     rendered.

           (b)       While EDS is primarily providing services to Wall Data
                     under this Agreement, EDS may from time to time provide
                     certain hardware, Software and other items as an incidental
                     part of the Services. With the exception of manufacturers'
                     or licensors' warranties which EDS is able to pass through
                     for Wall Data's benefit, such hardware, Software and other
                     items are provided on an "AS IS" basis without warranty. In
                     all cases where EDS has not committed to a specific
                     performance standard, EDS will use reasonable care in
                     providing services.

                     EDS will assign to Wall Data any rights it obtains under
                     warranties given by third party suppliers in connection
                     with any services, hardware, Software or other items
                     provided by EDS pursuant to this Agreement to the extent
                     that such rights are assignable. To the extent that any
                     such warranties are not assignable, EDS agrees that it
                     will, upon the request of Wall Data, take commercially
                     reasonable action to enforce any applicable warranty which
                     is enforceable by EDS in its own name. However, EDS will
                     have no obligation to resort to litigation or other formal
                     dispute resolution procedures to enforce such warranties,
                     unless Wall Data agrees to reimburse EDS for all expense
                     incurred therewith, including reasonable attorney's fees.
                     Subject to the foregoing sentence, in the event of a
                     nonconformance or other performance-related issue with
                     respect to any third-party Software, hardware or services
                     provided through EDS, EDS will coordinate and be the point
                     of contact for resolution of such nonconformance or
                     performance-related issue with the applicable vendor, and
                     will use commercially reasonable efforts (a) to manage such
                     vendor in accordance with the terms and conditions of their
                     respective agreement, (b) to cause the respective vendor to
                     promptly repair or replace the nonconforming item in
                     accordance with the such vendor's warranty or to remedy the
                     performance-related issue in accordance with the terms of
                     the respective vendor's agreement, and (c) to replace
                     nonperforming third party vendors with appropriate vendors
                     recommended by EDS and reasonably approved by Wall Data.

           (c)       EXCEPT AS SPECIFICALLY STATED IN THIS AGREEMENT, EDS MAKES
                     NO REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED,
                     REGARDING ANY MATTER, INCLUDING THE MERCHANTABILITY,
                     SUITABILITY, ORIGINALITY, FITNESS FOR A PARTICULAR USE OR
                     PURPOSE, OR RESULTS TO BE DERIVED FROM THE USE OF ANY
                     SERVICES, HARDWARE, SOFTWARE OR OTHER ITEMS PROVIDED UNDER

                     claims, actions, damages, liabilities, costs and expenses,
                     including reasonable attorneys' fees and expenses, arising
                     out of any claims related to 



                                       27
<PAGE>   29

                     (i) the abuse or the fraudulent use of the Networking and
                     Telecommunication Services by Wall Data and not EDS or any
                     its agents or subcontractors, which services are provided
                     or made available under this Agreement and (ii) any
                     information, data or message transmitted over the network
                     by Wall Data that constitutes libel, slander, infringement
                     of copyright, invasion of privacy, and/or alteration of
                     private records and data. Any credits received by EDS from
                     a Vendor or LEC as set forth in Section 2.3(d) of this
                     Agreement shall be passed through to Wall Data. EXCEPT AS
                     SPECIFICALLY STATED IN THIS AGREEMENT, EDS MAKES NO
                     REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED,
                     REGARDING THE WARRANTIES OF MERCHANTABILITY, SUITABILITY,
                     ORIGINALITY, FITNESS FOR A PARTICULAR PURPOSE, OR RESULTS
                     TO BE DERIVED FROM THE USE OF ANY NETWORKING, VOICE OR DATA
                     SERVICE, EQUIPMENT OR OTHER MATERIALS PROVIDED UNDER THIS
                     AGREEMENT.

10.2       Cross Indemnification. EDS and Wall Data each agree to indemnify,
           defend and hold harmless the other from any and all damages,
           liabilities, costs and expenses, including reasonable attorneys' fees
           and expenses, arising out of, under or in connection with any claim,
           demand, charge, action, cause of action, or other proceeding:

           (a)       for rent or utilities at any location where the indemnitor
                     is financially responsible under this Agreement for such
                     rent or utilities; or

           (b)       resulting from an act or omission of the indemnitor in its
                     capacity as an employer of a person and arising out of or
                     relating to (i) federal, state or other laws or regulations
                     for the protection of persons who are members of a
                     protected class or category of persons, (ii) sexual
                     discrimination or harassment, (iii) work related injury or
                     death, (iv) accrued employee benefits not expressly assumed
                     by the indemnitee, and (v) any other aspect of the
                     employment relationship or its termination (including
                     claims for breach of an express or implied contract of
                     employment) and which, in all such cases, arose when the
                     person asserting the claim, demand, charge, action, cause
                     of action or other proceeding was or purported to be an
                     employee of the indemnitor.

10.3       Intellectual Property Indemnification. EDS and Wall Data each agree
           to defend the other against any action to the extent that such action
           is based on a claim that Software or confidential information
           provided by the indemnitor, or any part thereof, (a) infringes a
           copyright perfected under United States statute, (b) infringes a
           patent granted under United States law, or (c) constitutes an
           unlawful disclosure, use, or misappropriation of another party's
           trade secret. The indemnitor will bear the expense of such defense
           and pay any damages and attorneys' fees which are attributable to
           such claim finally awarded by a court of competent jurisdiction.
           Neither EDS nor Wall Data shall be liable to the other for claims of
           indirect or contributory infringement or for claims that the software
           programs of the Wall Data-Vendor Software or EDS-Vendor Software so
           infringes. If the Software or confidential information becomes the
           subject of a claim under this Section, or in the indemnitor's opinion
           is likely to become the subject of such a claim, then the indemnitor
           may, at its option, (a) replace or 



                                       28
<PAGE>   30

           modify the Software or confidential information to make it
           noninfringing or cure any claimed misuse of another's trade secret,
           or (b) procure for the indemnitee the right to continue using the
           Software or confidential information pursuant to this Agreement, or
           (c) replace the Software with reasonably equivalent Software which
           is noninfringing or which is free of claimed misuse of another's
           trade secret. Any costs associated with implementing any of the
           above alternatives shall be borne by the indemnitor.

10.4       Personal Injury and Property Damage.

           (a)       EDS and Wall Data shall each be responsible for damages to
                     their respective tangible personal or real property
                     (whether owned or leased), and each party agrees to look
                     only to their own insuring arrangements (if any) with
                     respect to such damages.

           (b)       EDS and Wall Data each shall be responsible for claims for
                     the death of or personal injury to any person (including
                     any employee of either party), and claims for damages to
                     any third party's tangible personal or real property
                     (whether owned or leased), in accordance with the common
                     law of the jurisdiction in which such claim occurred. Each
                     party shall indemnify, defend and hold harmless the other
                     party from any and all claims, actions, damages,
                     liabilities, costs and expenses, including without
                     limitation, reasonable attorneys' fees and expenses,
                     arising out of claims for which the indemnitor is
                     responsible under the preceding sentence.

           (c)       EDS and Wall Data waive all rights to recover against each
                     other for any loss or damage to their respective tangible
                     personal or real property (whether owned or leased) from
                     any cause covered by insurance maintained by each of them,
                     including their respective deductibles or self-insured
                     retentions. EDS and Wall Data will cause their respective
                     insurers to issue appropriate waivers of subrogation rights
                     endorsements to all property insurance policies maintained
                     by each party.

10.5       Indemnification Procedures.

           (a)       Notice and Control. The indemnification obligations set
                     forth in this Article shall not apply unless the party
                     claiming indemnification:

                     (i)         Notifies the other promptly of any matters in
                                 respect of which the indemnity may apply and of
                                 which the notifying party has knowledge, in
                                 order to allow the indemnitor the opportunity
                                 to investigate and defend the matter; provided
                                 that the failure to so notify shall only
                                 relieve the indemnitor of its obligations under
                                 this Article if and to the extent that the
                                 indemnitor is prejudiced thereby; and

                     (ii)        Gives the other party full opportunity to
                                 control the response thereto and the defense
                                 thereof, including, without limitation, any
                                 agreement relating to the settlement thereof;
                                 provided that, the indemnitee will have the
                                 right to participate in any legal proceeding to
                                 contest and defend a claim for 



                                       29
<PAGE>   31

                                indemnification involving a third party and to
                                be represented by legal counsel of its choosing,
                                all at the indemnitee's cost and expense.

           (b)       Settlement. The indemnitor shall not be responsible for any
                     settlement or compromise made without its consent (provided
                     the indemnitor is not in material breach of its indemnity
                     obligations hereunder). The indemnitee agrees to cooperate
                     in good faith with the indemnitor at the request and
                     expense of the indemnitor.

10.6       Limitation of Liability.

           (a)       Direct Damages. Subject to Section 10.6(c), in the event
                     either party shall be held liable to the other for any
                     matter arising out of, under, or in connection with this
                     Agreement, whether based on an action or claim in contract,
                     equity, negligence, tort or otherwise, the amount of
                     damages recoverable against such party for all events, acts
                     or omissions shall not exceed, in the aggregate, the [*] of
                     the [*] by Wall Data to EDS under this Agreement ([*] for
                     [*] or [*] [*]) during the [*] immediately preceding the
                     date that the first such claim or action arose.

           (b)       Indirect Damages. Subject to Section 10.6(c), for any
                     matter arising out of, under, or in connection with this
                     Agreement, whether based on an action or claim in contract,
                     equity, negligence, tort or otherwise, in no event will the
                     measure of damages payable by either party include, nor
                     will either party be liable for, any amounts for loss of
                     income, profit or savings or indirect, incidental,
                     consequential, or punitive damages of any party, including
                     third parties.

           (c)       Exceptions. The limitations set forth in Sections 10.6(a)
                     and (b) will not apply with respect to (i) claims that are
                     covered by the indemnification provisions set forth in
                     Sections 10.1(d), 10.2, 10.3 and 10.4(b) of this Agreement,
                     and (ii) Wall Data's obligation to pay charges to EDS for
                     the Services rendered under this Agreement.

           (d)       Survival. The provisions of this Section 10.6 will survive
                     the expiration or termination of this Agreement for any
                     reason.

10.7       Contractual Statute of Limitations. No claim and demand for
           arbitration or cause of action which arose out of an event or events
           which occurred more than four years prior to the filing of a demand
           for arbitration or suit alleging a claim or cause of action may be
           asserted by either party against the other party.

10.8       Acknowledgment. EDS and Wall Data each acknowledge that the
           limitations and exclusions contained in this Article have been the
           subject of active and complete negotiation between the parties and
           represent the parties' agreement based upon the level of risk to EDS
           and Wall Data associated with their respective obligations under this
           Agreement and the payments to be made to EDS under this Agreement.

                            ARTICLE XI. MISCELLANEOUS

11.1       Right of the Parties to Engage in Other Activities. Nothing in this
           Agreement will impair either party's rights to acquire, license,
           market, distribute, develop for itself or others or have others
           develop for the respective parties similar technology performing the
           same or similar functions as the technology and the Services
           contemplated by this Agreement.

11.2       Binding Nature and Assignment. This Agreement shall be binding on the
           parties hereto and their respective successors and assigns. Except as
           provided in Section 9.5, neither party may, nor shall have the power
           to, assign this Agreement without the prior written consent of the
           other party, which consent shall not be unreasonably withheld.
           Notwithstanding the foregoing, EDS will have the right to subcontract
           all or any portion of the Services; provided, however, that, other
           than for temporary or incidental services, Wall Data has given its
           written consent for the subcontracting of such services, which
           consent will not be unreasonable withheld. Unless Wall Data provides
           EDS with a reasonable objection to such subcontracting arrangement
           within two weeks after Wall Data's receipt of notice (as provided
           herein), EDS will proceed with the implementation of such arrangement
           as specified in the notice. In no event shall any such subcontract
           relieve EDS of any of its obligations hereunder.

11.3       Notices. Wherever under this Agreement one party is required or
           permitted to give written notice to the other, such notice shall be
           deemed given the third day after its mailing by one party, postage
           prepaid, to the other party addressed as follows:

           the other party.

11.4       Counterparts. This Agreement may be executed in several counterparts,
           all of which taken together shall constitute one single agreement
           between the parties hereto.

11.5       Headings. The Article and Section headings and the table of contents
           used herein are for reference and convenience only and shall not
           enter into the interpretation hereof.

11.6       Relationship of Parties. EDS, in furnishing the Services to Wall Data
           hereunder, is acting only as an independent contractor and under no
           circumstances will EDS be deemed to be in any relationship with Wall
           Data carrying with it fiduciary or trust responsibilities, whether
           through

<PAGE>   34

           partnership or otherwise. EDS does not undertake by this Agreement
           or otherwise to perform any obligation of Wall Data, whether
           regulatory or contractual, or to assume any responsibility for Wall
           Data's business or operations. EDS has the sole right and obligation
           to supervise, manage, contract, direct, procure, perform or cause to
           be performed, all work to be performed by EDS hereunder unless
           otherwise provided herein.

           written consent of the other.

11.8       Approvals and Similar Actions. Where agreement, approval, acceptance,
           consent or similar action by either party is required by any
           provision of this Agreement, such action shall not be unreasonably
           delayed or withheld.

11.9       Force Majeure. Each party shall be excused from performance hereunder
           (other than performance of obligations to make payment) for any
           period and to the extent that it is prevented from performing
           pursuant hereto, in whole or in part, as a result of delays caused by
           the other or third parties or an act of God, war, civil disturbance,
           court order, labor dispute, or other cause beyond its reasonable
           control, including failures or fluctuations in electrical power,
           heat, light, air conditioning or telecommunications equipment, and
           such nonperformance shall not be a default hereunder or a ground for
           termination hereof. The party relieved from performance under this
           Section shall use all commercially reasonable efforts and diligence
           to overcome the force majeure event and continue performance of its
           obligations. Notwithstanding the foregoing, in the event a force
           majeure event occurs and such event lasts continuously for a period
           of at least three months and, as a result of such force majeure
           event, EDS is prevented from providing Services pursuant to this
           Agreement, then. In addition, after such three-month period:

           (a)       If EDS can still perform 80% or more of the Services, then
                     this Agreement shall remain in effect through its Term even
                     though the force majeure event may continue; provided,
                     however, Wall Data may discontinue payments under this
                     Agreement to EDS related to the affected portion of the
                     Services which EDS is prevented from performing, and obtain
                     the same services from a third party.

           (b)       If EDS can still perform 50% to 79% of the Services, then
                     Wall Data may elect to either (i) continue the portion of
                     this Agreement relating to the Services that EDS is still
                     able to perform, despite the force majeure event, and
                     terminate the portion of this Agreement relating to the
                     Services affected by the force majeure event, or (ii)
                     terminate the entire Agreement, provided that (1) Wall Data
                     gives EDS prior written notice of such election to
                     terminate and states in such notice the termination date,
                     and (2) except as provided below, prior to such termination
                     date, Wall Data pays EDS a termination fee calculated as
                     follows: (x) if termination occurs in years one through
                     four (measured from the Effective Date), the termination
                     fee shall be [*] of the aggregate invoice amount described
                     in Section 9.4 for the fourth anniversary termination
                     option, plus [*] of the Hardware Charges component, (y) if
                     termination occurs in years five or

                     six (measured from the Effective Date), the termination
                     fee shall be [*] of the aggregate invoice amount described
                     in Section 9.4 for the sixth anniversary termination
                     option, plus [*] of the Hardware Charges component, and
                     (z) if termination occurs in years eight through Term
                     (measured from the Effective Date), the termination fee
                     shall be [*] of the aggregate invoice amount described in
                     Section 9.4 for the eighth anniversary termination option,
                     plus [*] of the Hardware Charges component.

                     If a force majeure event occurs after the adoption and
                     implementation of a new disaster recovery plan negotiated
                     in good faith and mutually agreed to by Wall Data and EDS,
                     and if Wall Data elects to terminate this Agreement under
                     the circumstances described in this Section 11.9(b), then
                     Wall Data will not be required to pay EDS the termination
                     fees described in this Section 11.9(b); provided, however,
                     that Wall Data will still be required to pay EDS [*] of
                     the Hardware Charges and any actual and unavoidable third
                     party fees and charges incurred by EDS as a result of such
                     termination.

           (c)       If EDS can still perform less than 50% of the Services,
                     then Wall Data may elect to either (i) continue the portion
                     of this Agreement relating to the Services that EDS is
                     still able to perform, despite the force majeure event, and
                     terminate the portion of this Agreement relating to the
                     Services affected by the force majeure event, or (ii)
                     terminate the entire Agreement, provided that (1) Wall Data
                     gives EDS prior written notice of such election to
                     terminate and states in such notice the termination date,
                     and (2) prior to such termination date, Wall Data pays EDS
                     the Hardware Charges described in Section 9.4.

           During the three-month period and for any period thereafter that EDS
           is prevented from providing Services pursuant to this Section, Wall
           Data may discontinue payments under this Agreement to EDS related to
           the affected portion of the Services (except for actual and
           unavoidable third party charges incurred by EDS).

11.10      Severability. If any term or provision of this Agreement or the
           application thereof to any person or circumstances shall, to any
           extent, be held invalid or unenforceable, the remainder of this
           Agreement or the application of such term or provision to persons or
           circumstances other than those as to which it is invalid or
           unenforceable shall not be affected thereby, and each term and
           provision of this Agreement shall be valid and enforceable to the
           extent permitted by law.

11.11      Waiver. No delay or omission by either party hereto to exercise any
           right or power hereunder shall impair such right or power or be
           construed to be a waiver thereof. A waiver by either of the parties
           hereto of any of the covenants to be performed by the other or any
           breach thereof shall not be construed to be a waiver of any
           succeeding breach thereof or of any other covenant herein contained.
           Subject to the limitations set forth in this Agreement, all remedies
           provided for in this Agreement shall be cumulative and in addition to
           and not in lieu of any other remedies available to either party at
           law, in equity or otherwise.

11.12      Attorneys' Fees. If there is any legal action with regard to the
           enforcement of an award granted under Section 8.3, the prevailing
           party shall be entitled to recover reasonable attorneys' fees

           and expenses and other costs incurred in that action or proceeding, 
           in addition to any other relief to which it may be entitled.

11.13      Media Releases. All media releases, public announcements and public
           disclosures by Wall Data or EDS relating to this Agreement or its
           subject matter, including, without limitation, promotional or
           marketing material (but not including any announcement intended
           solely for internal distribution at Wall Data or EDS, as the case may
           be, or any disclosure required by legal, accounting or regulatory
           requirements beyond the reasonable control of Wall Data or EDS, as
           the case may be) shall be coordinated with and approved by Wall Data
           and EDS prior to the release thereof.

11.14      No Third Party Beneficiary. Nothing in this Agreement may be relied
           upon or shall benefit any party other than the parties hereto.

11.15      Entire Agreement. This Agreement, including any Schedules or Exhibits
           referred to herein and attached hereto, each of which is incorporated
           in this Agreement for all purposes, constitutes the entire agreement
           between the parties with respect to the subject matter of this
           Agreement and there are no representations, understandings or
           agreements relating to this Agreement which are not fully expressed
           herein. No amendment, modification, waiver or discharge hereof shall
           be valid unless in writing and signed by an authorized representative
           of the party against which such amendment, modification, waiver or
           discharge is sought to be enforced.

11.16      Governing Law. This Agreement shall be governed by and construed in
           accordance with the laws of the State of Washington, without giving
           effect to principles of conflict of laws.

           IN WITNESS WHEREOF, EDS and Wall Data have each caused this Agreement
to be signed and delivered by its duly authorized officer, all as of the
