                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information, and the Company's Consolidated Financial Statements and Notes
thereto, appearing elsewhere in this Prospectus.
 
                                  THE COMPANY
 
     Synon Corporation ("Synon" or the "Company") is a leading provider of
enterprise software application development tools and related professional
services designed to enable organizations to rapidly design and deploy
mission-critical software applications. Over the last 14 years the Company has
established the leading market position for International Business Machines
Corporation ("IBM") AS/400 software development tools, having sold approximately
6,000 licenses to customers located in approximately 80 countries. In late 1994,
the Company introduced Obsydian, a multi-platform software application
development tool designed to expand the Company's presence in the AS/400 market.
In order to capitalize on the growth of the Microsoft Corporation ("Microsoft")
Enterprise Windows NT computing environment, in March 1997, the Company released
the Obsydian for Windows NT Back Office Generator (the "Windows NT generator").
 
     Obsydian is an integrated business-oriented software development tool that
provides customers with the ability to rapidly develop, deploy and enhance
sophisticated software applications across multiple computing platforms.
Obsydian's technology employs a practical model-based approach to software
design that uses large reusable business objects ("patterns") to reduce
application development lead times. The Obsydian product line includes multiple
code generators that allow developers to deploy applications across different
computing environments, including AS/400, Windows NT and UNIX. The Company is
currently developing a generator with Java capability.
 
     The Company currently sells application development tools primarily in two
distinct markets: the IBM AS/400 market and the emerging Windows NT market.
According to research estimates by International Data Corporation, there were
approximately 79,000 new AS/400 systems sold in 1996, representing approximately
13% growth over 1995, bringing the installed base to approximately 372,000
systems at December 31, 1996. Company management estimates that approximately
half of the new AS/400 systems sold in 1996 include language compilers which the
Company considers potential customer sites. Dataquest has estimated that the
Windows NT-based application server computer systems market will grow at a
compound annual growth rate of 42% per year through 2000 and is expected to
reach approximately five million systems by 1999. The Company believes that both
of these markets represent significant opportunities for its software
development products and services. To date, the Company has derived
substantially all of its revenue from application development tools and services
for the AS/400 market, but believes that an increasing percentage of its revenue
will come from tools and services for the Windows NT market.
 
     The Company intends to leverage its expertise and reputation in AS/400
software development tools to establish Obsydian as the leading multi-platform
application development tool for diverse computing environments. The Company's
major strategies are to: (i) capitalize on its significant customer base and
established market position; (ii) repeat its success in the AS/400 market in the
emerging Windows NT market; (iii) capitalize on its established development and
marketing relationships with IBM and Microsoft; (iv) build upon the Company's
existing technological leadership; (v) facilitate customers' adoption and use of
Synon's technology through a range of professional services; and (vi) leverage
its existing worldwide presence.
 
     The Company sells its products and services through its direct sales forces
in North America, the United Kingdom, France, Italy and Australia and through a
network of distributors in Europe, Asia and Latin America.
 
     The Company was organized under the laws of the United Kingdom in 1983 and
reorganized in Delaware in 1990. Unless the context otherwise requires,
references in this Prospectus to "Synon" or the "Company," relate to Synon
Corporation, a Delaware corporation, its predecessor Synon Limited, organized
under the laws of the United Kingdom, and its wholly-owned subsidiaries. The
Company's principal executive offices are located at 1100 Larkspur Landing
Circle, Larkspur, California 94939 and its telephone number at that address is
(415) 461-5000.

BRIEF HISTORY OF PROFITABILITY; ACCUMULATED DEFICIT
 
     The Company has been profitable on an annual basis since 1993. However, the
Company incurred annual losses of $8.5 million, $6.3 million and $10.7 million
in 1990, 1991 and 1992, respectively, and as of March 31, 1997 on a pro forma
basis had an accumulated deficit of approximately $33.0 million, of which
approximately $20.9 million resulted from operating losses. As a result of these
losses, the Company has experienced constraints in the availability of working
capital. Moreover, the Company has reported working capital deficits at December
31, 1996 and in each of the years in the five year period ended December 31,
1996 and at March 31, 1997. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources." Moreover, even in the profitable years, the Company has experienced
frequent quarterly operating losses, and in each of the last four years
substantially all of the operating income has been based on profits achieved in
the fourth quarter. There can be no assurance that the Company will be
profitable in any future period, and recent operating results are not
necessarily indicative of future financial performance.
 
FLUCTUATIONS IN QUARTERLY RESULTS; SEASONALITY
 
     The Company's quarterly revenue and operating results have fluctuated
significantly in the past due to seasonal trends, cost overruns associated with
certain fixed price services projects, sales staff turnover and timing of new
product deliveries. The Company's quarterly revenue and operating results are
likely to vary significantly in the future as a result of these and a number of
other factors including the demand for the Company's software; the size, timing
and contractual terms of significant orders; the timing and significance of
software product enhancements and new software product announcements by the
Company or its competitors; the productivity of the Company's sales channels;
changes in pricing policies by the Company or its competitors; changes in the
Company's or its competitors' business strategies; budgeting cycles of its
potential customers; changes in the mix of software products and services the
Company sells; changes in the mix of revenue attributable to domestic and
international sales; software defects and other product quality problems; the
ability of the Company to recruit and retain qualified personnel; investments to
develop sales distribution channels; changes in the level of operating expenses;
and general domestic and international economic and political trends.
 
     The Company's license revenue has experienced and is expected to continue
to experience a high degree of seasonality, in part due to customer buying
patterns. In recent years, the Company has generally had stronger sales of its
software products during the quarter ending in December and weaker sales in the
following quarter. In addition, sales of the Company's software products tend to
be flat in the third quarter compared to the second quarter, due to reduced
sales activity in the summer months, especially in Europe. Moreover, the Company
has experienced frequent quarterly operating losses, and in each of the last
four years substantially all of its operating income has been based on profits
achieved in the fourth quarter. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     In addition, the timing of revenue recognition can diverge from
expectations as a result of a variety of factors, including the timing of
contract execution and delivery, and customer acceptance, if applicable.
 
                                        5
<PAGE>   7
 
When an undeliverable product affects the usability of other products in a
customer order, recognition of that customer order's revenue may be delayed
until all products constituting part of that customer order can be delivered.
Specifically, quarterly results in 1995 were affected as revenue recognition of
Obsydian sales which included the AS/400 Non-Programmable Terminal ("NPT")
generator was delayed until the generator was delivered in December 1995. These
and other factors affecting the timing of revenue recognition can contribute to
fluctuations in quarterly results.
 
     Software revenue is also difficult to forecast because the market for
high-end client/server software products is rapidly evolving, especially for the
emerging Windows NT market, and because the Company's sales cycle, from initial
contact to purchase and implementation, varies substantially from customer to
customer. In the event of any downturn in potential customers' businesses or the
economy in general, or a lack of market acceptance of the Windows NT computing
platform in general or the Company's Obsydian for Windows NT product in
particular, planned purchases of the Company's products may be deferred or
canceled, which could have a material adverse effect on the Company's business,
operating results and financial condition. In addition, the Company's North
American sales operation historically has not achieved levels of productivity
realized elsewhere in the business. The Company has recently implemented a
change in the structure and leadership of the North American sales operation,
but there can be no assurance that the operation's performance will improve. See
"-- Continued Importance of Synon/2E; Dependence on Obsydian; Dependence on
Market for High-End Client/Server Applications," "-- Limited Customer Use of
Obsydian for Windows NT; Market Acceptance of Windows NT Platform" and "-- Sales
and Marketing Productivity."
 
     The Company typically ships product orders shortly after receipt, and
consequently, order backlog at the beginning of any quarter has in the past
represented an inconsequential portion of that quarter's revenue. As a result,
to achieve its quarterly revenue objectives, the Company is dependent upon
obtaining orders in any given quarter for shipment in that quarter. Furthermore,
the Company has often recognized a substantial portion of its revenue in the
last month, or even weeks or days, of a quarter and therefore quarterly revenue
is difficult to predict with any significant degree of accuracy. The Company's
expense levels are based, in significant part, on the Company's expectations as
to future revenue and are, therefore, relatively fixed in the short term. If
revenue levels fall below expectations, net income would likely be
disproportionately adversely affected because a proportionately smaller amount
of the Company's expenses varies with its revenue. There can be no assurance
that the Company will be able to achieve or maintain profitability on a
quarterly or annual basis in the future. Due to all of the foregoing factors, it
is likely that in some future quarter the Company's operating results will be
below the expectations of public market analysts and investors. In such event,
the price of the Company's Common Stock would likely be materially adversely
affected.
 
CONTINUED IMPORTANCE OF SYNON/2E; DEPENDENCE ON OBSYDIAN; DEPENDENCE ON MARKET
FOR HIGH-END CLIENT/SERVER APPLICATION DEVELOPMENT TOOLS
 
     In the last three years, revenue attributable to the Synon/2E product
family has declined as a percentage of the Company's total revenue, but
continues to be important to the Company. The Company derived approximately 87%,
60% and 45% of its license revenue in 1994, 1995 and 1996, respectively, from
the Company's Synon/2E product family and approximately 100%, 95% and 88% of its
maintenance revenue in 1994, 1995, and 1996, respectively, from the Company's
Synon/2E product family. Moreover, the license revenue attributable to the
Synon/2E product family has declined significantly in absolute dollars in each
of the last three years. Although the Company continues to invest in
enhancements to its Synon/2E product family and plans to continue product
updates and introduction of new releases for such products, the Company expects
further declines in Synon/2Eproduct family license revenue and declines in
Synon/2E product family maintenance and professional services revenue, both in
absolute dollars and as a percentage of total revenue, as customers migrate away
from the Synon/2E product. In the event that the decline in revenue from the
Synon/2E product family is not more than offset by growth in revenue
attributable to the Obsydian product family, the Company's results of operations
will be materially adversely affected.
 
                                        6
<PAGE>   8
 
     Beginning in 1995, a substantial portion of the Company's license revenue
has been attributable to sales of the Obsydian product family, which accounted
for approximately 13%, 40% and 55% of the Company's license revenue in 1994,
1995 and 1996, respectively. The Company expects the Obsydian product family to
account for an increasingly significant portion of the Company's revenue for the
foreseeable future. However, total license revenue declined in each of 1994,
1995 and 1996 as the growth in Obsydian product family license revenue was more
than offset by declines in Synon/2E product family license revenue. Growing
Obsydian product family revenue will be required not only to counteract the
effect of declining Synon/2E product family revenue, but also to generate in
large part any future Company revenue growth. As a result, factors adversely
affecting the pricing of or demand for the Obsydian product family, such as
competition or technological change, would have a material adverse effect on the
Company's business, operating results and financial condition. Moreover, the
Company's future financial performance will depend, in significant part, on the
successful development, introduction and customer acceptance of new and enhanced
versions of the Company's Obsydian product and other software products that keep
pace with continuing changes in software application development technology,
evolving industry standards and changing customer preferences. In particular,
customer acceptance of the recently released Obsydian for the Enterprise Windows
NT computing platform, which the Company expects will account for an
increasingly significant portion of Obsydian revenue in the future, is important
to the Company's future success. There can be no assurance that the Company will
continue to be successful in marketing, or that customers will accept, the
Obsydian product family or any new or enhanced software products, including
Obsydian for the Windows NT computing platform. See "--Limited Customer Use of
Obsydian for Windows NT, Market Acceptance of Windows NT Platform."
 
     Although the Company has recently experienced growth in sales of Obsydian,
continued growth is in part dependent on ongoing demand for high-end
client/server applications, and there can be no assurance that such market will
continue to grow. The market for software used in the development, deployment
and management of high-end client/server applications is relatively new and is
characterized by ongoing technological developments, frequent new product
announcements and introductions, evolving industry standards and changing
customer requirements. The Company's future financial performance will depend in
large part on continued growth in the number of organizations adopting high-end
client/server applications and computing environments and the number of
applications developed for use in those environments. If the high-end
client/server market fails to grow or grows more slowly than the Company
currently anticipates, the Company's business, operating results and financial
condition would be materially and adversely affected. Moreover, there can be no
assurance that the Company's customers will expand usage of the Company's
software on an enterprise-wide basis or implement new software products
introduced by the Company. The failure of the Company's software to perform
according to customer expectations or otherwise to be deployed on an
enterprise-wide basis would have a material adverse effect on the ability of the
Company to increase revenue from new as well as existing customers. See
"Business -- Industry Background," "-- Strategy," "-- Technology and Products"
and "-- Competition."
 
LIMITED CUSTOMER USE AND MARKET ACCEPTANCE OF OBSYDIAN FOR WINDOWS NT; MARKET
ACCEPTANCE OF WINDOWS NT PLATFORM
 
     The Company expects to generate a substantial portion of its future revenue
from sales of Obsydian for the Windows NT computing platform. Consequently,
customer acceptance of such product is important to the Company. See
"--Continued Importance of Synon/2E; Dependence on Obsydian; Dependence on
Market for High-End Client Server Applications." The Company first shipped
Obsydian for the Windows NT computing platform in March 1997. To date, only a
limited number of the Company's customers have completed the development of
software applications for the Windows NT computing platform using Obsydian. As
with all complex software products, a substantial investment of time and
resources is required for users to become educated and fluid with the Obsydian
product family, and to date only a relatively small group of users is qualified
to use such products or manage the Windows NT operating environment more
generally. If any of the Company's customers are not able to successfully
develop and deploy applications for the Windows NT computing platform using
Obsydian, the Company's
 
                                        7
<PAGE>   9
 
reputation could be damaged and future sales of Obsydian for the Windows NT
computing platform could suffer. In addition, even if customers are successful
developing and deploying applications for the Windows NT computing platform
using Obsydian, limited market acceptance of the Windows NT platform would
adversely affect sales of Obsydian for the Windows NT computing platform. There
can be no assurance that existing customers will be successful developing or
deploying applications for the Windows NT computing platform using Obsydian,
that the Obsydian for Windows NT product will achieve significant market
acceptance or that the Windows NT platform will become widely adopted. The
failure of any of these to occur would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
COMPETITION
 
     The software development market is highly fragmented and serviced by many
firms. The market for advanced software used in the development, deployment and
management of high-end client/server application software systems is intensely
competitive and characterized by rapidly changing technology, evolving industry
standards, frequent new product introductions and rapidly changing customer
requirements. The Company's development tools are targeted primarily at
developers of large business applications running on the AS/400 and the Windows
NT operating platform. In the market for high-end client/server application
development software tools, the Company expects to compete primarily with Forte
Software, Inc. and Texas Instruments Incorporated with respect to users of the
Windows NT operating platform, and currently competes primarily with Progress
Software Corporation and several small software companies with respect to users
of the AS/400. In the market for less complex client/server application
development software tools, the Company competes primarily with Powersoft
Corporation, IBM's Visual Age product line and Microsoft's Visual Basic with
respect to users of the Windows NT operating platform and with IBM's Visual Age
product line with respect to users of the AS/400.
 
     Software that can be developed and deployed using the Company's Obsydian
environment can also be implemented using a combination of first generation
application development tools and more powerful server programming techniques
such as stored procedures in relational databases, C or C++ programming, and
networking and database middleware to connect the various components.
Consequently, the Company experiences competition from potential customers'
decisions to pursue this approach as opposed to utilizing an application
environment such as Obsydian. Similarly, the Company's products compete against
the alternative of conventional software development in the AS/400's native RPG
language. As a result, the Company must continuously educate existing and
prospective customers as to the advantages of the Company's products. There can
be no assurance that these customers or potential customers will perceive
sufficient value in the Company's products to justify purchasing them.
 
     The Company also competes indirectly with database vendors such as Oracle
Corporation ("Oracle"), Informix Corporation ("Informix") and others that offer
their own development tools for use with their databases. The Company may in the
future face additional direct or indirect competition from IBM or Microsoft in
the event that such companies continue to develop their own application
development tools for the AS/400, Windows NT or other computing platforms or
enter into strategic relationships with any of the Company's competitors. In
addition, since the software industry has relatively low barriers to entry, the
Company may in the future face additional competition from start-up or other
companies in the software application development tool industry.
 
     Most of the Company's current competitors have, and future competitors may
have, significantly greater financial, technical, marketing and other resources
than the Company. The Company's competitors may be able to respond more quickly
to new or emerging technologies and changes in customer requirements or devote
greater resources to the development, promotion and sale of their products than
the Company. Also, most current and potential competitors have greater name
recognition and more extensive customer bases that could be leveraged, thereby
gaining market share to the Company's detriment. The Company expects to face
additional competition as other established and emerging companies enter the
application development tools market and new products and technologies are
 
                                        8
<PAGE>   10
 
introduced. Increased competition could result in price reductions, reduced
purchases of licenses, professional services and maintenance, lower gross
margins or loss of market share, any of which would materially adversely affect
the Company's business, operating results and financial condition.
 
     In addition, current and potential competitors have established or may
establish cooperative relationships among themselves or with third parties or
make strategic acquisitions to increase the ability of their products to address
the needs of the Company's prospective customers. Accordingly, it is possible
that new competitors or alliances among current and new competitors may emerge
and rapidly acquire significant market share. There can be no assurance that the
Company will be able to compete successfully against current and future
competitors or that competitive pressures faced by the Company will not
materially adversely affect its business, operating results and financial
condition. Further, there can be no assurance that products or technologies
developed by others will not render the Company's products non-competitive or
obsolete. In addition, regardless of the Company's success in the marketplace, a
negative perception of the Company generated by industry analysts or the public
more generally could detract from the Company's competitiveness. The Company's
market is still evolving and there can be no assurance that the Company will be
able to compete successfully against current and future competitors, and the
failure to do so successfully will have a material adverse effect upon the
Company's business, operating results and financial condition. See
"Business -- Competition."
 
SALES AND MARKETING PRODUCTIVITY
 
     An important element of the Company's strategy is to increase the
productivity and effectiveness of its sales and marketing organizations. In
particular, the Company intends to improve the productivity of its North
American sales operation, which has not achieved levels of productivity realized
elsewhere in the business. See "-- Fluctuations in Quarterly Results;
Seasonality." As one step toward achieving such improvement, the Company has
instituted a change in leadership of the North American sales operation. The
Company believes that its ability to improve sales and marketing productivity,
as well as its future success more generally, will depend in large part upon its
ability to identify, attract, train and retain highly skilled sales, marketing
and management personnel. Competition for such personnel in the computer
software industry is intense. There can be no assurance the Company will be
successful in identifying, attracting, training and retaining such personnel, or
retaining existing key personnel, each of whom presently has an at-will
employment relationship with the Company. The failure to do any of the foregoing
could have a material adverse effect on the Company's business, operating
results or financial condition.
 
DEPENDENCE ON RELATIONSHIPS WITH IBM AND MICROSOFT
 
     The Company's development, marketing and distribution activities are in
part dependent on the Company's relationships with IBM's AS/400 division and
Microsoft. Although certain aspects of the Company's relationships with each of
IBM's AS/400 division and Microsoft are contractual in nature, many important
aspects of each relationship depend on the continued cooperation of IBM and
Microsoft, respectively, and there can be no assurance that the Company will be
able to work successfully with either IBM or Microsoft for an extended period of
time. Specific risks to each relationship include the fact that the Company and
IBM and Microsoft also compete in the area of development tools for one or all
of the AS/400, Windows NT and other computing platforms, as well as the risks of
divergence in strategy between Synon and either company, a change in focus by
either company or establishment of strategic relationships between either
company and a competitor or competitors of Synon, any of which events would
materially adversely impact Synon's ability to develop, market, sell or support
its products. See "-- Competition."
 
POTENTIAL FINANCIAL EXPOSURE FROM FIXED-PRICE CONTRACTS
 
     The Company has in the past entered into agreements with customers
involving application development projects, including multi-million dollar
projects, in which the Company has committed to achieve a specific result for a
fixed price. The Company's operating margins for 1995 and 1996 were negatively
impacted by cost overruns, and in certain cases losses, incurred in completing
certain fixed-
 
                                        9
<PAGE>   11
 
price projects. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations." The Company has implemented new practices intended
to enable it to more effectively evaluate its ability to achieve the result
required by a fixed-price contract before entering into any such contract in the
future. However, there can be no assurance that the cost of fulfilling the
Company's obligations under any such contract will not exceed the Company's
estimate of such costs or the fixed price payable to the Company under such
contract, in which event the Company's operating results would likely be
materially adversely affected.
 
RISKS ASSOCIATED WITH DISTRIBUTION CHANNELS
 
     To date, the Company has sold its products primarily through its direct
sales force and distributors. Revenue from distributors accounted for
approximately 26%, 21% and 30% of the Company's software license revenue for
1994, 1995 and 1996, respectively. In addition, the Company relies on its
foreign distributors to provide first level customer support. The success of the
Company is therefore dependent in significant part upon the performance of its
distributors, which is primarily outside the Company's control. The Company's
ability to achieve significant revenue growth in the future will depend in large
part on its success in maintaining and establishing additional relationships
with distributors worldwide. The loss of any of the Company's major
distributors, or their promotion of competitive products, or the failure of
these distributors to take the actions necessary to support Obsydian, especially
Obsydian for the Windows NT computing platform, or the failure of the Company to
attract new distributors, could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business -- Strategy"
and "-- Sales and Marketing."
 
LENGTHY SALES CYCLE
 
     The evaluation of, and purchase decision with respect to, the Company's
software products generally involves a significant commitment of management
attention and resources by prospective customers. Accordingly, the Company's
sales process is often subject to delays associated with the long approval
process that generally accompanies significant initiatives or capital
expenditures. For these and other reasons, the sales cycle associated with the
license of the Company's products is often lengthy (typically three to nine
months) and subject to a number of significant delays over which the Company has
little or no control. It is likely that the Company will continue to experience
a lengthy sales cycle in the future, which could contribute to variability in
quarterly operating results. See "-- Potential Fluctuations in Quarterly
Results; Seasonality" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
     Revenue from foreign operations accounted for approximately 47%, 48% and
46% of the Company's total revenue in 1994, 1995 and 1996, respectively.
Although the Company has had international operations for a number of years,
there can be no assurance that the Company will be able to successfully market,
sell and deliver its products in international markets in the future. In
addition, the Company believes that in order to increase sales opportunities and
profitability, as well as to meet growing market needs, it may be required to
expand its international operations, including hiring additional personnel and
recruiting additional distributors. To the extent that the Company is unable to
do so in a timely manner, the Company's growth, if any, in international sales
may be limited, and the Company's business, operating results and financial
condition could be materially adversely affected.
 
     The Company's international operations are exposed to risks from
fluctuations in foreign currency exchange rates with respect to a number of
currencies, including fluctuations among and between the United States dollar,
British pound, German deutschemark, Japanese yen, French franc and Italian lira.
The Company does not currently engage in foreign currency management activities
or hedging transactions. Additional risks inherent in the Company's
international business activities generally include the impact of possible
recessionary environments in economies outside the United States, unexpected
changes in government policies and regulatory requirements, tariffs, export
controls and other trade
 
                                       10
<PAGE>   12
 
barriers, costs of localizing products for foreign markets, lack of acceptance
of localized products in foreign countries, longer accounts receivable payment
cycles, difficulties and costs of staffing and managing international
operations, potentially adverse tax consequences, restrictions on the
repatriation of earnings, the burdens of complying with a wide variety of
foreign laws, political instability and transportation delays. There can be no
assurance that the Company or its distributors will be able to sustain or
increase international revenue from licenses or from maintenance or professional
services, or that the foregoing factors will not have a material adverse effect
on the Company's results associated with its international operations, and,
consequently, on the Company's overall business, operating results and financial
condition. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Overview" and "Business -- Sales and Marketing."
 
DEPENDENCE ON PROPRIETARY RIGHTS AND TECHNOLOGY; RISKS OF INFRINGEMENT
 
     The Company's success is heavily dependent upon proprietary technology. The
Company also believes that factors such as the technological and creative skills
of its personnel, new product developments, frequent product enhancements, name
recognition and reliable product maintenance are essential to establishing and
maintaining a technology leadership position. The Company relies primarily on a
combination of copyright and trademark laws, trade secrets, confidentiality
procedures and contractual provisions to protect its proprietary rights. The
Company seeks to protect its software, documentation and other written materials
under trade secret and copyright laws, which afford only limited protection. The
Company currently has no patents or patent applications pending. Despite
precautions taken by the Company, it may be possible for unauthorized third
parties to copy aspects of its products or future products or to obtain and use
information that the Company regards as proprietary. In particular, for the
Synon Model Applications ("SMA") financial product and class libraries, the
Company provides its licensees with access to its data model and other
proprietary information underlying its licensed applications. There can be no
assurance that the Company's means of protecting its proprietary rights now or
in the future will be adequate or that the Company's competitors will not
independently develop similar or superior technology. Litigation may be
necessary in the future to enforce the Company's intellectual property rights,
to protect the Company's trade secrets or to determine the validity and scope of
the proprietary rights of others. Such litigation could result in substantial
costs and diversion of resources and could have a material adverse effect on the
Company's business, operating results and financial condition.
 
     The Company, Dysys Limited, a United Kingdom company ("Dysys"), and Simon
Williams and Melinda Horton, founders and major stockholders of the Company, are
parties to an agreement dated September 15, 1992 (the "Dysys Agreement") in
connection with which the Company acquired certain intellectual property from
Dysys which was included in the Company's Obsydian product. In connection with
the Dysys Agreement, the Company currently incurs a liability to pay Mr.
Williams and Ms. Horton a 1.0% and 0.5% royalty, respectively, on Obsydian
license and maintenance revenue for all transactions entered into through June
30, 1999. Pursuant to the Dysys Agreement, Mr. Williams and Ms. Horton also
retain certain rights with respect to the intellectual property, including the
non-exclusive right to use and exploit it under certain circumstances, including
the Company's failure to pay required royalty amounts required in connection
with the Dysys Agreement. See "Certain Transactions -- Dysys Agreement."
 
     Policing unauthorized use of the Company's software is difficult, and,
while the Company does not believe software piracy is a significant problem to
the Company at present, there can be no assurance that it will not become a
problem in the future. In addition, the laws of some foreign countries do not
protect the Company's proprietary rights to the same extent as do the laws of
the United States. The Company is not aware that any of its software product
offerings infringe the proprietary rights of third parties, but there can be no
assurance that third parties will not claim infringement by the Company with
respect to current or future products. The Company expects that software
developers will increasingly be subject to infringement claims as the number of
products and competitors in the Company's industry segment grows and the
functionality of products in different industry segments overlaps. Any such
claims, with or without merit, could be time-consuming, result in costly
litigation, cause product shipment
 
                                       11
<PAGE>   13
 
delays or require the Company to enter into royalty or licensing agreements.
Such royalty or licensing agreements, if required, may not be available on terms
acceptable to the Company or at all, which could have a material adverse effect
on the Company's business, operating results and financial condition. Any such
delays or reductions in product shipments could materially and adversely affect
the Company's business, operating results and financial condition. See
"Business -- Intellectual Property and Other Proprietary Rights."
 
RAPID TECHNOLOGICAL CHANGE; PRODUCT DEVELOPMENT RISKS
 
     The market for the Company's products is subject to rapid technological
change, changing customer needs and evolving industry standards that may render
existing products and services obsolete. As a result, the Company's position in
its existing markets or other markets that it may enter could be eroded rapidly
by product advances. The Company's vulnerability to rapid technological change
and changing customer needs is heightened by the focus of its product
development efforts on the Obsydian product line and Obsydian for the Windows NT
computing platform.
 
     The Company's product development efforts are expected to require, from
time to time, substantial investments by the Company, but there can be no
assurance that the Company will have sufficient resources to make the necessary
investments. In addition, the Company has in the past experienced
development delays, and there can be no assurance that the Company will not
experience such delays in the future, which could delay or prevent the
successful development, introduction or marketing of new or enhanced products
such as the Java generator. Such products, even if developed successfully on a
timely basis, may not meet the requirements of the marketplace or achieve market
acceptance. If the Company is unable, for technological or other reasons, to
develop and introduce new and enhanced products in a timely manner, the
Company's business, results of operations and financial condition could be
materially adversely affected.
 
     Software products as complex as those offered by the Company may contain
errors that may be detected at any point in the products' life cycles. There can
be no assurance that, despite testing by the Company and by current and
potential customers, errors will not be found, resulting in loss of, or delay
in, market acceptance and sales, diversion of development resources, injury to
the Company's reputation, or increased service and warranty costs, any of which
could have a material adverse effect on the Company's business, results of
operations and financial condition. See "Business -- Technology and Products"
and "-- Product Development."
 
DEPENDENCE ON KEY PERSONNEL; NEW SYSTEMS AS PUBLIC COMPANY
 
     Synon's success depends on the continued contributions of certain senior
corporate managers and key employees, each of whom has an at-will employment
relationship with the Company. The loss of services of any of such personnel
could have a material adverse effect on the Company. The Company also depends on
its continued ability to attract and retain other highly skilled and qualified
personnel, and there can be no assurance that the Company will be successful in
attracting and retaining such personnel. See "Management -- Executive Officers,
Directors and Key Employees."
 
     Moreover, in order to compete effectively and manage its obligations as a
public company, the Company must continue to implement and improve information
systems, procedures and controls and expand, train and manage its work force.
 
FINANCIAL EXPOSURE FROM EXCESS FACILITIES
 
     As a result of the restructuring of its European operations, the Company
currently has excess facilities under long term leases in the United Kingdom.
While these facilities are currently sublet, there can be no assurance that the
Company will not incur liabilities in connection with these excess facilities in
the future, which could have a material adverse effect on the Company's
business, operating results and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of
 
                                       12
<PAGE>   14
 
Operations -- Liquidity and Capital Resources" and Note 12 of Notes to
Consolidated Financial Statements.
 
PRODUCT LIABILITY
 
     The Company's license agreements with its customers typically contain
provisions designed to limit the Company's exposure to potential product
liability claims. It is possible, however, that the limitation of liability
provisions contained in the Company's license agreements may not be effective
under existing or future laws of certain jurisdictions. Although the Company has
not experienced any material product liability claims to date, the sale and
support of products by the Company may entail the risk of such claims, and there
can be no assurance that the Company will not be subject to such claims in the
future. A successful product liability claim brought against the Company could
have a material adverse effect on the Company's business, operating results and
financial condition.
 
EFFECT OF CERTAIN CHARTER PROVISIONS; LIMITATION OF LIABILITY OF DIRECTORS;
ANTITAKEOVER EFFECTS OF DELAWARE LAW
 
     Effective upon the closing of this Offering, the Company will be authorized
to issue up to 5,000,000 shares of undesignated Preferred Stock. The Board of
Directors has the authority to issue the Preferred Stock in one or more series
and to fix the price, rights, preferences, privileges and restrictions thereof,
including dividend rights, dividend rates, conversion rights, voting rights,
terms of redemption, liquidation preferences and the number of shares
constituting a series or the designation of such series, without any further
vote or action by the Company's stockholders. The issuance of any such Preferred
Stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of delaying,
deferring or preventing a change in control of the Company without further
action by the stockholders and may adversely affect the market price of the
Common Stock and the voting and other rights of the holders of Common Stock. The
issuance of Preferred Stock with voting and conversion rights may adversely
affect the voting power of the holders of Common Stock, and may under certain
circumstances involve the loss of voting control to others. The Company has no
current plans to issue any shares of Preferred Stock.
 
     Certain provisions of the Company's Amended and Restated Certificate of
Incorporation and Bylaws eliminate the right of stockholders to act by written
consent without a meeting and specify certain procedures for nominating
directors and submitting proposals for consideration at stockholder meetings.
Such provisions are intended to enhance the likelihood of continuity and
stability in the composition of the Board of Directors and in the policies
formulated by the Board of Directors and to discourage certain types of
transactions which may involve an actual or threatened change of control of the
Company. Such provisions are designed to reduce the vulnerability of the Company
to an unsolicited acquisition proposal and, accordingly, could discourage
potential acquisition proposals and could delay or prevent a change in control
of the Company. Such provisions are also intended to discourage certain tactics
that may be used in proxy fights but could also have the effect of discouraging
others from making offers for the Company's shares and, consequently, may
inhibit fluctuations in the market price of the Company's Common Stock that
could result from actual or rumored takeover attempts. These provisions may also
have the effect of reducing or preventing changes in the management of the
Company.
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law (the "Antitakeover Law"), which regulates corporate acquisitions. The
Antitakeover Law prevents certain Delaware corporations, including those having
securities listed for trading on the Nasdaq National Market, from engaging,
under certain circumstances, in a "business combination" with any "interested
stockholder" for three years following the date that such stockholder became an
interested stockholder. For purposes of the Antitakeover Law, a "business
combination" includes, among other things, a merger or consolidation involving
the Company and the interested stockholder, as well as the sale of more than ten
percent (10%) of the Company's assets. In general, the Antitakeover Law defines
an "interested stockholder" as any entity or person beneficially owning 15% or
more of the outstanding voting stock of the Company and any entity or person
affiliated with or controlling or controlled by such entity or person. A
Delaware
 
                                       13
<PAGE>   15
 
corporation may "opt out" of the Antitakeover Law with an express provision in
its original certificate of incorporation or an express provision in its
certificate of incorporation or bylaws resulting from amendments approved by the
holders of at least a majority of the Company's outstanding voting shares. The
Company has not "opted out" of the provisions of the Antitakeover Law. See
"Description of Capital Stock."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of a substantial number of shares of Common Stock in the public
market following this Offering could adversely affect the market price for the
Company's Common Stock. See "Description of Capital Stock" and "Shares Eligible
for Future Sale."
 
IMMEDIATE DILUTION
 
     The Offering price is substantially higher than the book value per share of
the Company's Common Stock. Investors purchasing Common Stock in this Offering
will, therefore, incur immediate dilution of $          in the pro forma net
tangible book value per share of Common Stock (based upon the Offering price of
$          per share and after deducting estimated underwriting discounts and
commissions and Offering expenses payable by the Company) from the Offering
price and will incur additional dilution upon the exercise of outstanding stock
options. See "Dilution."
 
CONTROL BY PRINCIPAL STOCKHOLDERS, OFFICERS AND DIRECTORS
 
     Upon completion of this Offering, the Company's executive officers,
directors and principal stockholders and their affiliates will beneficially own
approximately     % of the outstanding shares of Common Stock (     % if the
Underwriters' over-allotment option is exercised in full). As a result, these
stockholders, if acting in concert, will be able to control most matters
requiring stockholder approval, including the election of directors, and the
approval of mergers, consolidations and sales of all or substantially all of the
assets of the Company. This may prevent or discourage tender offers for the
Company's Common Stock unless the terms are approved by such stockholders. See
"Principal and Selling Stockholders."
 
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this Offering there has been no public market for the Common Stock
of the Company. The Offering price will be determined by negotiations among the
Company, the Selling Stockholders and the representatives of the Underwriters.
See "Underwriting" for a discussion of the factors to be considered in
determining the Offering price. There can be no assurance that an active public
market will develop or be sustained after this Offering or that the market price
of the Common Stock will not decline below the Offering price. The market price
of the Company's Common Stock is likely to be highly volatile and may be
significantly affected by future announcements concerning the Company or its
competitors, quarterly or annual variations in results of operations,
announcements of technological innovations, the introduction of new products or
changes in pricing policies by the Company or its competitors, proprietary
rights or other litigation, changes in earnings estimates by analysts, the
Company's failure to meet analysts' estimates or other factors. In addition,
stock prices for many technology companies fluctuate widely for reasons which
may be unrelated to results of operations. These fluctuations, as well as
general economic, market and political conditions such as recessions or military
conflicts, may materially and adversely affect the market price of the Company's
Common Stock.
 
DISCRETION AS TO USE OF PROCEEDS
 
     The primary purposes of this Offering are to create a public market for the
Company's Common Stock, to facilitate future access to public markets and to
obtain additional working capital. As of the date of this Prospectus, the
Company has no specific plans to use the net proceeds from this Offering other
than for working capital and general corporate purposes. Accordingly, the
Company's management will
 
                                       14
<PAGE>   16
 
retain broad discretion as to the allocation of the net proceeds from this
Offering. Pending any such uses, the Company plans to invest the net proceeds in
investment grade, interest-bearing securities. See "Use of Proceeds."
 
ABSENCE OF DIVIDENDS
 
     The Company has not in the past declared or paid dividends on its Common
Stock, and does not anticipate paying cash dividends on its Common Stock in the
foreseeable future. In addition, the Company's bank line of credit agreement
contains a restrictive covenant that prohibits the Company from paying cash
dividends without the prior written consent of the lender.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the           shares of
Common Stock offered by the Company hereby are estimated to be approximately
$          (approximately $          if the Underwriters' over-allotment option
is exercised in full), assuming an Offering price of $          per share and
after deducting the estimated underwriting discounts and estimated Offering
expenses.
 
     The primary purposes of this Offering are to create a public market for the
Company's Common Stock, to facilitate future access to public markets and to
obtain additional working capital. The Company expects to use the net proceeds
of this Offering for working capital and other general corporate purposes. A
portion of the net proceeds may also be used for the acquisition of businesses,
products and technologies that are complementary to those of the Company,
although the Company has no current plans, agreements or commitments and is not
currently engaged in any negotiations with respect to any such transactions.
Pending such uses, the net proceeds of this Offering will be invested in
investment grade, interest-bearing securities.
 
     The Company will not receive any proceeds from the sale of the shares of
Common Stock offered by the Selling Stockholders hereby.
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid cash dividends on its Common Stock.
The Company currently expects to retain future earnings, if any, for use in the
operation and expansion of its business and does not anticipate paying any cash
dividends in the foreseeable future. In addition, the Company's bank line of
credit agreement contains a restrictive covenant that prohibits the Company from
paying dividends without the prior written consent of the lender.

     The following table sets forth (i) the actual capitalization of the Company
derived from its financial statements as of March 31, 1997, (ii) pro forma
capitalization of the Company, giving effect to (a) the amendment and
restatement of the Company's Certificate of Incorporation to provide for
authorized capital stock of 50,000,000 shares of Common Stock and 5,000,000
shares of undesignated Preferred Stock, (b) the conversion of all outstanding
shares of Preferred Stock into           shares of Common Stock immediately
prior to the closing of the Offering, and (c) except as otherwise indicated, a
one-for-two reverse stock split of the Company's Common Stock effected in June
1997, and (iii) the pro forma as adjusted capitalization of the Company to
reflect the sale by the Company of           shares of Common Stock pursuant to
the Offering at an assumed Offering price of $          per share and the
receipt by the Company of the estimated net proceeds therefrom, after deducting
estimated underwriting discounts and estimated Offering expenses. The

                                    DILUTION
 
     The pro forma net tangible book value of the Company as of March 31, 1997
was $     million or $          per share of Common Stock. Pro forma net
tangible book value per share represents the Company's total tangible assets
less total liabilities, divided by the number of outstanding shares of the
Company's Common Stock on a pro forma basis after giving effect to the
conversion of all outstanding shares of Preferred Stock into           shares of
Common Stock immediately prior to closing of the Offering. After giving effect
to the sale of           shares of Common Stock offered hereby at an assumed
Offering price of $          per share and the receipt by the Company of the
estimated net proceeds therefrom, after deducting the estimated underwriting
discounts and commissions and Offering expenses payable by the Company, the
Company's pro forma net tangible book value at March 31, 1997 would have been
$          or $          per share of Common Stock. This represents an immediate
increase in pro forma net tangible book value of $          per share to
existing stockholders and an immediate dilution in pro forma net tangible book
value of $          per share to new investors. The following table illustrates
this per share dilution:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements relating to future
events or the future financial performance of the Company. All statements, trend
analyses and other information contained herein relative to markets for the
Company's products and trends in revenue, gross margin and anticipated expense
levels, as well as other statements including such words as "anticipate,"
"believe," "plan," "estimate," "expect," and "intend" and other similar
expressions constitute forward-looking statements. These forward-looking
statements are subject to business and economic risks, and the Company's actual
results of operations may differ materially from those contained in the
forward-looking statements as a result of certain factors, including those set
forth under "Risk Factors" and elsewhere in this Prospectus.
 
OVERVIEW
 
  History
 
     Building on its years of experience selling application development tools
for the IBM System 3X environment, the Company in 1988 introduced its first
integrated application development toolset, Synon/2E, in concert with IBM's
introduction of the AS/400 computer system. Aided by its marketing and
development relationships with IBM, the Company captured a leading position in
the AS/400 application development tools market and grew rapidly and profitably
in 1988 and 1989.
 
     Due to a variety of factors, including increased competition, slowed growth
in the AS/400 market, the relocation of corporate and certain development
functions to the U.S. in 1990, reserves for excess facilities costs in the U.K.
in 1990 through 1992, and the write down of the value of an acquired distributor
business in 1992, the Company sustained net losses of $8.5 million, $6.3 million
and $10.7 million in 1990, 1991 and 1992, respectively. These net losses
generated substantial accumulated deficits of which $20.9 million remained as of
March 31, 1997. During this time, the Company raised approximately $15 million
of additional capital from existing venture capital investors and from IBM to
fund its operations. Additionally, the Company grew its professional services
business, primarily in North America, to provide necessary technology transfer
and customer implementation support for its products. The business returned to
modest profitability in 1993 on the strength of increased license revenue, third
party product offerings, services business expansion, growing maintenance
revenue from the Company's existing customer base and cost controls.
 
     Recognizing the need to enhance its product line, the Company in 1992 began
developing its next generation, multi-platform product, Obsydian, which it
introduced in late 1994. Anticipating an emerging opportunity in the Windows NT
market, in January 1996 the Company entered into a sponsored development
agreement with Microsoft to accelerate the development of Obsydian's Windows NT
generator and enhance the marketing and promotion of the product. See
"Business -- Third Party Relationships." The Windows NT generator was released
in March 1997.
 
  Revenue
 
     Prior to the introduction of Obsydian in late 1994, all of the Company's
license revenue was generated from the Synon/2E product family. License revenue
from the Obsydian product family has grown rapidly in each of the three years
since the introduction of Obsydian, both in absolute dollars and as a percentage
of total revenue, while license revenue from the Synon/2E product family has
decreased, both in absolute dollars and as a percentage of total revenue. The
Company expects that license revenue from the Obsydian product family will
continue to account for an increasing percentage of total license revenue.
Moreover, notwithstanding an increase in license revenue from the Synon/2E
product family in the first quarter of 1997 as compared to the first quarter in
1996, the Company expects that such revenue will continue to decline both in
absolute dollars and as a percentage of total license revenue. In the event that
the decline in revenue from the Synon/2E product family is not more than offset
by growth in revenue attributable to the Obsydian product family, the Company's
results of operations will be
 
                                       19
<PAGE>   21
 
materially adversely affected. See "Risk Factors -- Continued Importance of
Synon/2E; Dependence on Obsydian; Dependence on Market for High-End
Client/Server Application Development Tools."
 
     Maintenance revenue, which has reflected the cumulative effect of increases
or decreases in license revenue over time, has not varied significantly in
absolute dollars or as a percentage of total revenue over the last nine
quarters. Through 1996, over 90% of total maintenance revenue was related to
licenses of the Synon/2E product family. The Company expects that maintenance
revenue related to the Synon/2E product family will begin to decline in future
periods, both in absolute dollars and as a percentage of total maintenance
revenue, as existing users of the Synon/2E product family migrate to the
Obsydian product family or otherwise cease to use the Synon/2E products, and
expects maintenance revenue related to the Obsydian product family to increase
as a percentage of total maintenance revenue.
 
     Services revenue is comprised principally of professional services, which
constituted a significant portion of the Company's total revenue in each of
1994, 1995 and 1996. The Company views professional services, which consist of
application development, education, and consulting, as important to customers'
successful implementation of the Company's software products. The Company has
developed an extensive professional services practice in North America in order
to address the market opportunity there and derives a substantial majority of
its total services revenue from service projects in North America. Services
revenue in the remainder of the world is a smaller portion of total services
revenue because much of the services are provided by the Company's distributors.
 
     The Company has historically derived a significant portion of its total
revenue from international operations. International revenue, which is defined
by the Company as revenue generated outside of North America, constituted 47%,
48%, 46% and 44% of total revenue in 1994, 1995, 1996 and the first quarter of
1997, respectively. The Company expects international revenue to continue to
account for a significant portion of total revenue for the foreseeable future.
The Company has not historically managed its foreign currency exchange risks by
entering into foreign currency management programs or hedging transactions. As a
result, the Company is exposed to currency exchange fluctuation risks, as well
as certain other financial risks associated with international operations. See
"Risk Factors -- Risks Associated with International Operations."
 
  Channel Mix
 
     The Company markets its software primarily through its direct sales force
in North America, the United Kingdom, France, Italy and Australia, and through
distributors in the remainder of Europe, Latin America and Asia. Most of the
Company's foreign distributors (other than those in Japan) have the principal
relationship with the customers and perform first-level customer support and
maintenance services. License revenue from the Company's distributors accounted
for approximately 26%, 21%, 30% and 23% of the Company's total license revenue
in 1994, 1995, 1996 and the first quarter of 1997, respectively. The Company's
ability to achieve significant revenue growth in the future will depend in part
on its success in maintaining existing relationships with its distributors and
in developing new relationships with distributors, independent software vendors
and systems integrators. See "Risk Factors -- Risks Associated with Distribution
Channels."
 
  Revenue Recognition
 
     The Company recognizes software license revenue when the end user customer
executes a non-cancelable license agreement either with the Company or one of
its distributors and the product has been shipped to the customer, provided that
no significant contractual obligations remain and collection of the related
receivable is considered probable by management. Maintenance revenue from
customer maintenance, support and upgrade service agreements is recognized
ratably over the maintenance period, which is typically twelve months. The
Company provides most of its services under time and materials arrangements and
recognizes revenue for these engagements as services are performed. In addition,
the Company has in the past undertaken several fixed-price application
development projects. Approximately 19%, 15%, 12% and 15% of the Company's
services revenue in 1994, 1995, 1996 and the quarter
 
                                       20

ended March 31, 1997, respectively, was generated from fixed-price contracts.
The Company recognizes revenue for these projects on a percentage of completion
basis. To the extent the Company's estimates of project completion prove to be
inaccurate, the Company's operating results in future periods will be affected
by adjustments as the estimates are revised. In addition, management is required
to make estimates and assumptions in connection with determining the
technological feasibility of software under development, related research and
development cost capitalization and product life amortization periods for
capitalized software costs. See Note 1 of Notes to Consolidated Financial
Statements.

  Quarters Ended March 31, 1996 and 1997
 
     License Revenue. License revenue consists of fees from the licensing of the
Company's products. License revenue increased 29% from $3.5 million in the first
quarter of 1996 to $4.5 million in the first quarter of 1997 and comprised 20%
and 24%, respectively, of total revenue in those quarters. The
 
                                       21
<PAGE>   23
 
increase reflected continued growth in Obsydian product family sales and strong
sales of Synon/2E - related products, especially in North America. License
revenue from the Obsydian product family increased from $1.7 million in the
first quarter of 1996 to $2.1 million in the same quarter of 1997 and comprised
49% and 47%, respectively, of total license revenue in these quarters. License
revenue from the Synon/2E product family increased from $1.8 million in the
first quarter of 1996 to $2.4 million in the same quarter of 1997 and comprised
51% and 53%, respectively, of total license revenue in these quarters.
 
     Maintenance Revenue. Maintenance revenue consists of fees received under
maintenance, support and upgrade agreements, which typically have a term of
twelve months. Maintenance agreements for the Synon/2E product family are
typically priced at a percentage of the list price of the license annually.
Maintenance agreements for the Obsydian product family consist of separate
customer support and upgrade agreements. See "Technology and Products."
Maintenance revenue in the first quarter of 1997 declined 1% from the first
quarter of 1996, continuing the trend of maintenance revenue remaining
essentially flat compared to the prior year, and comprised 32% and 29%,
respectively, of total revenue in those quarters.
 
     Services Revenue. Services revenue consists of fees for education,
consulting and application development services designed to assist effective
customer use of Synon's technology. Services revenue increased 6% from $8.2
million in the first quarter of 1996 to $8.6 million in the first quarter of
1997 and comprised 48% and 47%, respectively, of total revenue in those
quarters. Services revenue in the first quarter of 1996 was negatively affected
by two fixed-price projects. The Company recognized reduced revenue per hour on
these contracts in accordance with the percentage of completion revenue
recognition method. See "--Overview--Revenue Recognition" above.
 
     Cost of License Revenue. Cost of license revenue includes costs directly
associated with software products sold, including tangible product costs of
media and documentation, royalties associated with the sale of Obsydian and
third party products and amortization of capitalized software development costs.
Cost of license revenue, excluding amortization of capitalized software
development costs, increased 118% from $144,000 in the first quarter of 1996 to
$314,000 in the first quarter of 1997 and increased from 4% to 7%, respectively,
of license revenue in those quarters. The absolute dollar increase was primarily
due to a $75,000 increase in tangible product costs related primarily to license
volume increases in the first quarter of 1997. Amortization of software
development costs, which is included in reported cost of revenue, totaled
$544,000 and $460,000 in the first quarter of 1996 and 1997, respectively,
reflecting a change in mix of remaining capitalized assets and their related
useful lives. The Company expects cost of license revenue to increase in future
periods due in part to increased royalties associated with Obsydian and third
party technology incorporated into the Company's products and to increased
tangible product cost.
 
     Cost of Maintenance Revenue. Cost of maintenance revenue consists primarily
of compensation and other costs for customer support personnel, facilities and
equipment costs, third party royalties related to maintenance revenue and the
tangible costs of media, documentation and shipping relating to product updates
and new releases provided to customers. Cost of maintenance revenue, after
rounding, increased 3% from $1.5 million in the first quarter of 1996 to $1.5
million in the first quarter of 1997 and increased from 28% to 29%,
respectively, of maintenance revenue in those quarters. The increases were
attributable primarily to staffing increases in 1996 necessary to support the
increase in number of Obsydian customers. This growth was partially offset by a
reduction in tangible product costs in the first quarter of 1997 because the
Company shipped fewer copies of new releases of the Obsydian product to existing
customers in that quarter than in the same quarter of 1996. The Company expects
that cost of maintenance revenue will increase in future periods due in part to
increases in personnel required to support a larger number of customers.
 
     Cost of Services Revenue. Cost of services revenue consists primarily of
compensation and other costs for personnel providing education, consulting and
application development services to Synon's customers, as well as facilities and
equipment costs and travel costs relating to services engagements.
 
                                       22
<PAGE>   24
 
Cost of services revenue decreased 2% from $6.8 million in the first quarter of
1996 to $6.6 million in the first quarter of 1997 and decreased from 83% to 77%,
respectively, of services revenue in those quarters. The decreases were
primarily due to higher costs incurred in the first quarter of 1996 in
connection with two fixed priced service projects and to higher overall staff
utilization in the first quarter of 1997. The Company has made a significant
investment in the internal training of its services personnel in order to
provide quality education, consulting and application development services to
its customers for the Obsydian product. The Company expects cost of services
revenue to increase in future periods.
 
     Sales and Marketing. Sales and marketing expenses consist primarily of
compensation for sales and marketing personnel and costs of travel,
entertainment, facilities and equipment, marketing collateral, advertising,
trade shows and other marketing programs. Sales and marketing expenses increased
4% from $5.4 million in the first quarter of 1996 to $5.6 million in the first
quarter of 1997 and decreased from 32% to 30%, respectively, of total revenue in
those quarters. The dollar increase was due primarily to staffing increases and
associated costs incurred during the second half of 1996 and to fewer staff
vacancies in the first quarter of 1997 than in the first quarter of 1996. The
Company expects increased sales and marketing costs in 1997 as a result of costs
associated with the introduction and promotion of the Obsydian Windows NT
generator and the development of alternative sales channels.
 
     Research and Development. Research and development expenses consist
primarily of compensation and other personnel related expenses and costs for
computers, software, facilities and other equipment associated with the
development of new products and the enhancement of existing products. The
Company capitalizes the cost of research and development after technological
feasibility has been established according to the requirements of Financial
Accounting Standards ("FAS") No. 86. Research and development expenses, before
capitalization of software development costs, remained essentially flat at $2.2
million in the first quarter of 1996 and the first quarter of 1997 and decreased
from 13% to 12%, respectively, of total revenue in those quarters. Capitalized
software development costs increased by approximately $54,000 in the first
quarter of 1997 compared to the first quarter of 1996 due primarily to the costs
associated with developing and deploying the Windows NT generator and a major
release of the Obsydian product. Research and development costs, including
capitalization of software development costs, remained relatively flat from
quarter to quarter. The Company expects research and development expenses to
increase in future periods.
 
     General and Administrative. General and administrative expenses consist
primarily of personnel costs for finance, human resources, internal systems and
general management functions as well as related facility and equipment costs,
professional fees and bad debt expenses. General and administrative costs
increased 17% from $1.8 million in the first quarter of 1996 to $2.1 million in
the first quarter of 1997 and increased from 10% to 11%, respectively, of total
revenue in these quarters. These increases were due primarily to increases in
information systems staff and increased costs associated with internal system
development. The Company expects that general and administrative costs will
continue to increase as the Company invests in internal systems and incurs costs
associated with operating as a public company.
 
     Interest Income (Expense), Net. Interest income (expense) includes interest
expense from capital lease obligations and an IBM development loan offset by
interest earned on cash balances. The Company reported net interest expense of
$9,000 during the first quarter of 1996 compared with net interest income of
$4,000 in the first quarter of 1997. The change was due primarily to the
repayment in full of the remaining balance of the IBM development loan in
December 1996 and a reduction of capital lease obligations in 1996.
 
     Other Income (Expense), Net. Other income (expense) consists primarily of
foreign currency gains and losses. Other expense increased from $18,000 in the
first quarter of 1996 to $225,000 in the first quarter of 1997 and was comprised
almost entirely of foreign currency losses.
 
     Income Taxes. The Company's estimated effective income tax rate of 25% for
1997 applied to the first quarter remained essentially unchanged from the 1996
rate due to continued utilization of tax benefit
 
                                       23
<PAGE>   25
 
carryovers. The Company expects its effective income tax rate to increase as it
utilizes its tax benefit carryovers. See Note 9 of Notes to Consolidated
Financial Statements.
 
  Years Ended December 31, 1994, 1995 and 1996
 
     License Revenue. License revenue decreased 6% from $23.3 million in 1994 to
$22.0 million in 1995 and decreased 1% to $21.8 million in 1996. License revenue
represented 36%, 31% and 29% of total revenue in 1994, 1995 and 1996,
respectively. The decreases in absolute dollars and as a percentage of total
revenue in both 1995 and 1996 reflects a decline in the number of Synon/2E
product family licenses, which was only partially offset in both years by growth
in the number of licenses of the new Obsydian product family following its
introduction late in 1994. License revenue from the Obsydian product family has
grown rapidly, from $3.1 million in 1994 to $8.9 million in 1995 and to $12.0
million in 1996 and comprised 13%, 40% and 55%, respectively, of total license
revenue in those years. License revenue from the Synon/2E product family has
declined since the introduction of the Obsydian product, from $20.2 million in
1994 to $13.1 million in 1995 and to $9.8 million in 1996 and comprised 87%, 60%
and 45%, respectively, of total license revenue in those years. The decline in
Synon/2E product family sales reflects reduced demand for the Synon/2E product
family and a change in sales focus by direct sales channels from Synon/2E to
Obsydian. The decline in Synon/2E product family sales was expected after the
introduction of the Obsydian product and the change in sales focus by the
Company's direct sales channel.
 
     Initially, the Company sold Obsydian licenses primarily to existing
Synon/2E customers, primarily through its direct sales channels. These existing
Synon/2E customers accounted for 91% and 72% of Obsydian license revenue in 1994
and 1995, respectively. In 1996 the Company derived an increasing percentage of
its Obsydian license revenue from new customers, which the Company believes was
due to Obsydian's improved functionality and a greater number of customer
references for Obsydian. These new customers accounted for 9%, 28% and 40% of
Obsydian product family license revenue in 1994, 1995 and 1996, respectively. In
late 1995 and in 1996, Obsydian sales were increasingly generated by
international distributors, especially those in Europe and Latin America, as
they focused sales resources on Obsydian.
 
     Maintenance Revenue. Maintenance revenue increased 12% from $18.8 million
in 1994 to $21.1 million in 1995 and increased 1% to $21.3 million in 1996.
Maintenance revenue represented 29%, 30% and 28% of total revenues in 1994, 1995
and 1996, respectively. Maintenance revenue increased in absolute dollars in
1995 and 1996 due to the provision of maintenance, customer support and upgrades
to a larger installed customer base in each of those years, but the rate of
growth decreased from 1995 to 1996. Synon/2E maintenance revenue declined on an
annual basis from 1995 to 1996 by approximately 7%, reflecting lower Synon/2E
license sales and typical attrition of Synon/2E maintenance customers. The
Synon/2E maintenance revenue decline from 1995 to 1996 was offset by a 152%
increase in Obsydian maintenance revenue. Although there was no Obsydian
maintenance revenue in 1994 because the product was introduced late in that
year, Obsydian maintenance revenue comprised 5% and 12% of total maintenance
revenue in 1995 and 1996, respectively.
 
     Services Revenue. Services revenue increased 19% from $23.2 million in 1994
to $27.7 million in 1995 and increased 19% to $33.0 million in 1996. Services
revenue represented 35%, 39% and 43% of total revenues in 1994, 1995 and 1996,
respectively. Synon/2E projects accounted for the majority of services revenue
in each of 1994, 1995 and 1996, reflecting continued strong use of the Synon/2E
technology in the market and the mix of the Company's project work. Services
revenue in each year was derived primarily from projects in North America, where
the Company generated approximately 71%, 71% and 73% of its total services
revenue in 1994, 1995 and 1996, respectively.
 
     The Company's services revenue, as well as the related gross margins, for
1995 and 1996 was negatively impacted by reduced revenue per hour recognized in
connection with the completion of certain fixed-price projects in those years.
The Company has implemented new practices intended to enable the Company to more
effectively evaluate its ability to achieve the result required by a fixed-price
 
                                       24
<PAGE>   26
 
engagement at the agreed-upon price. For example, before it accepts any large
fixed-price engagement, the Company now undertakes a design phase engagement for
each project to more accurately define that project's scope and risks. As of
December 31, 1996, the Company had completed all significant fixed price
engagements undertaken prior to the implementation of these policies. The
Company continues to accept work under fixed-price contracts and faces risks
inherent to such contracts. See "Risk Factors -- Potential Financial Exposure
from Fixed-Price Contracts."
 
     Cost of License Revenue. Cost of license revenue, excluding amortization of
capitalized software development costs, decreased 32% from $2.3 million in 1994
to $1.6 million in 1995 and further decreased 27% to $1.1 million in 1996. Cost
of license revenue, excluding amortization of capitalized software development
costs, was 10%, 7% and 3% of license revenue in 1994, 1995 and 1996,
respectively. In each year, the largest contributing factor to the decrease was
a decline in third party royalty costs, which decreased from $1.7 million in
1994 to $745,000 in 1995 and to $322,000 in 1996, due to the reduction in sales
of third party products related to Synon/2E. The decreases in third party
royalty costs were partially offset by increased royalties of $257,000 and
$319,000 in 1995 and 1996, respectively, relating to increased sales of
Obsydian. The royalties due in connection with Obsydian license sales will be
approximately 1.7% of such sales in 1997 and are payable only with respect to
license agreements entered into prior to June 30, 1999. See "Certain
Transactions." Amortization of capitalized software development costs, which is
included in reported cost of license revenue, totaled $2.1 million, $2.5 million
and $2.0 million in 1994, 1995 and 1996, respectively. The amortized amount of
capitalized software development costs decreased in 1996 because most of such
costs related to the Synon/2E product family had been fully amortized by the end
of 1995 and the capitalized costs of Obsydian and the Windows NT generator were
early in their amortization lives.
 
     Cost of Maintenance Revenue. Cost of maintenance revenue increased 22% from
$4.3 million in 1994 to $5.2 million in 1995 and increased 15% to $6.0 million
in 1996 and represented 23%, 25% and 28%, respectively, of maintenance revenue
in those years. The increases in each year were primarily due to increases in
the number of customer support personnel necessary to maintain and support the
Obsydian product family.
 
     Cost of Services Revenue. Cost of services revenue increased 25% from $17.4
million in 1994 to $21.6 million in 1995 and increased 24% to $26.9 million in
1996 and represented 75%, 78% and 81%, respectively, of services revenue in
those years. The increases in each year were principally the result of higher
internal Obsydian training costs for consultants and excess labor costs on
certain fixed-price projects, particularly in the first quarter of 1996. The
projects caused lower gross margins on services revenue until their completion
in 1996. See "-- Services Revenue" and "-- Overview -- Revenue Recognition."
 
     Sales and Marketing. Sales and marketing expenses increased 1% from $25.7
million in 1994 to $25.9 million in 1995 but decreased by 3% to $25.0 million in
1996. Sales and marketing expenses were 39%, 37% and 33% of total revenue in
1994, 1995 and 1996, respectively. The decrease in sales and marketing expenses
in 1996 was due primarily to a reduction in the sales force in North America,
Asia and Japan in 1996, and the conversion of Germany, Holland and South Africa
from direct sales territories to territories served by distributors. The
decrease in 1996 was partially offset by approximately $659,000 of severance and
other costs associated with the closing of direct sales operations in those
territories.
 
     Research and Development. Research and development expenses, before
capitalization of software development costs, increased 6% from $6.7 million in
1994 to $7.2 million in 1995 and increased 20% to $8.6 million in 1996. Research
and development expenses, before capitalization of software development costs,
represented 10%, 10% and 11% of total revenue in 1994, 1995 and 1996,
respectively. The Company capitalized $2.6 million, $2.2 million and $2.6
million of software development costs in 1994, 1995 and 1996, respectively. The
decrease in capitalized software costs from 1994 to 1995 was due to higher
capitalized costs in 1994 associated with the completion and first release of
the Obsydian product. The increase in capitalized software costs from 1995 to
1996 was due to significant enhancements made
 
                                       25
<PAGE>   27
 
to the Obsydian product and the completion of development of the first release
of the Windows NT generator in 1996. See "-- Cost of License Revenue."
 
     General and Administrative. General and administrative expenses increased
5% from $7.6 million in 1994 to $8.0 million in 1995 and decreased 9% to $7.3
million in 1996. General and administrative expenses were 12%, 11% and 10% of
total revenue in 1994, 1995 and 1996, respectively. The increase in 1995
reflected higher bad debt expense during the year. Other than the increased bad
debt expense in 1995, general and administrative expenses in both absolute
dollars and as a percentage of total revenue decreased during 1995 and 1996 due
primarily to staff reductions.
 
     Interest Income (Expense), Net. Net interest expense decreased 34% from
$282,000 in 1994 to $185,000 in 1995 and further decreased 75% to $47,000 in
1996. The decreases in each year were the result of reductions in the Company's
capital lease and loan obligations.
 
     Other Income (Expense), Net. Net other income was $232,000 in 1994 and
$267,000 in 1995 due primarily to foreign exchange gains of $216,000 in 1994 and
$227,000 in 1995. Net other expense of $162,000 in 1996 was due primarily to a
$167,000 foreign exchange loss in that year.
 
     Income Taxes. The Company has significant net operating loss, foreign tax
credit and other tax credit carryovers remaining from losses incurred in prior
years. The Company's effective income tax rate was 25% for each of 1994, 1995
and 1996. See Note 9 of Notes to Consolidated Financial Statements. The Company
expects its effective income tax rate to increase after it utilizes its tax
benefit carryovers.

VARIABILITY OF QUARTERLY RESULTS
 
     The Company's business has experienced and is expected to continue to
experience significant seasonality, in part due to customer buying patterns and
lower demand in the summer months, particularly in Europe. In recent years, the
Company has generally had stronger sales of its software products in the quarter
ending in December and weaker sales in the following quarter. License revenue in
the fourth quarter of 1994, 1995 and 1996 represented 36%, 39% and 37%,
respectively, of full year license revenue. The fourth quarter revenue pattern
reflects the Company's end of year sales quotas and sales incentives, customer
purchasing and capital budgeting patterns and general software industry trends.
The Company expects this quarterly pattern to continue in the future. Due
primarily to IT department purchasing patterns and certain sales staff turnover
between quota years, the Company's first quarter license revenue has typically
been weaker than in other quarters. In addition, license revenue in the third
quarter has historically been relatively flat compared to the second quarter as
a result of generally reduced economic activity in the summer months,
particularly in Europe. The Company believes that these trends are likely to
continue.
 
     The Company recorded higher than normal license revenue in the fourth
quarter of 1995 due to the recognition of approximately $587,000 of Obsydian
license revenue attributable to products sold in prior quarters, which license
revenue was deferred and not recognized until the related AS/400 NPT generator
was delivered in December 1995. In addition, many customers delayed making
purchases of the Obsydian product until the AS/400 NPT generator was available,
contributing to an increased level of revenue in the fourth quarter 1995.
 
     The Company's primary annual user group conference was held in the third
quarter of 1994, the first quarter of 1995, and the second quarter of 1996. Fees
collected from those user group conferences contributed $614,000, $426,000 and
$428,000, respectively, to service revenues in those quarters. The Company's
user group conferences in general approximately break even, and accordingly the
expenses associated with these conferences increased cost of services revenue by
an amount similar to related revenue in each of these quarters. The Company's
European operations hold a user conference in the fourth quarter of each year,
having a similar but smaller effect on services revenue and cost of services
revenue.
 
     Sales and marketing expenses decreased in the first three quarters of 1996
compared to each quarter of 1995, due primarily to sales staff reductions and
reduced costs associated with marketing programs. In 1996, additional expense
reductions were realized in the third quarter because the savings from the
conversion of the Germany, Holland and South Africa direct sales territories to
distributor territories were no longer offset by severance and other closure
costs as they had been in the first two quarters of 1996. The increase in sales
and marketing expenses in the fourth quarter of each year reflects typical
increased compensation associated with higher license revenue.
 
     The Company typically ships product orders shortly after receipt, and
consequently, order backlog at the beginning of any quarter has in the past
represented an inconsequential portion of that quarter's revenue. As a result,
to achieve its quarterly revenue objectives, the Company is dependent upon
obtaining orders in any given quarter for shipment in that quarter. Furthermore,
the Company has often recognized a substantial portion of its revenue in the
last month, or even weeks or days, of a quarter and therefore quarterly revenue
is difficult to predict with any significant degree of accuracy. The Company's
expense levels are based, in significant part, on the Company's expectations as
to future revenue and are therefore relatively fixed in the short term. If
revenue levels fall below expectations, net income is likely to be
disproportionately adversely affected because a proportionately smaller amount
of the Company's expenses varies with its revenue. There can be no assurance
that the Company will be able to achieve or maintain profitability on a
quarterly or annual basis in the future. Due to all of the foregoing factors, it
is likely that in some future quarter the Company's operating results will be
below the expectations of public market analysts and investors. In such event,
the price of the Company's Common Stock would likely be materially adversely
affected. See "Risk Factors -- No Prior Market; Possible Volatility of Stock
Price."

LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has funded its operations since 1991 primarily by cash
generated from operations and through private sales of preferred equity
securities. For the three months ended March 31, 1997, approximately $2.7
million of cash was provided by operations due to the collection in cash of
significant fourth quarter 1996 license revenue. During 1994, 1995 and 1996,
approximately $4.8 million, $3.6 million and $3.5 million, respectively, of cash
was generated by operations, primarily as a result of net income and
depreciation and amortization, somewhat offset by growth in accounts receivable.
Cash generated by operations was further reduced by approximately $2.6 million,
$2.2 million and $2.6 million in 1994, 1995 and 1996, respectively, for research
and development costs incurred by the Company which were capitalized according
to FAS No. 86.
 
     The Company used cash for the acquisition of property and equipment, of
approximately $2.0 million, $1.0 million, $1.8 million and $609,000 in 1994,
1995, 1996 and the first quarter of 1997, respectively. These investing
activities were partially offset in 1994 by cash received from the repayment of
certain loans made to former officers of the Company.
 
     During 1994, 1995 and 1996 and the quarter ended March 31, 1997, the
Company did not incur any additional debt. The Company used cash generated by
operations to repay IBM approximately $325,000, $500,000, and $675,000 of its
development loan during 1994, 1995 and 1996, respectively, and to pay down
capital lease obligations by approximately $1.3 million, $877,000 and $517,000,
in 1994, 1995 and 1996, respectively. The IBM loan was paid in full by December
31, 1996.
 
     As of March 31, 1997, the Company had approximately $2.5 million of cash
and cash equivalents and a working capital deficit of $1.5 million. The Company
had a working capital deficit in each of the last three years. The Company had
available a working capital line of credit agreement with Silicon Valley Bank
(the "Bank") that expires on July 14, 1997, secured by substantially all of the
Company's assets. The line of credit bears interest at 1.25% above the Bank's
prime rate (8.5% as of April 30, 1997) and drawings are available up to 70% of
eligible receivables. Under the line of credit, the Bank is committed to lend up
to a maximum of $4.0 million, of which $3.6 million was available as of March
31, 1997 based on eligible receivables. The Company's line of credit contains
certain affirmative and restrictive covenants that are typical of commercial
lending arrangements. From time to time the Company has not been in compliance
with such covenants, although to date the Company has obtained waivers from the
Bank with respect to such noncompliance. There can be no assurance that the
Company will comply with these restrictions and covenants in the future or be
able to obtain waivers from the Bank in the event of noncompliance. There were
no borrowings under the line of credit at December 31, 1996 or March 31, 1997.
 
     The Company has approximately 34,406 square feet in excess facilities in
the United Kingdom under long term lease agreements which expire December 1999
through December 2014. These facilities are currently subleased to third parties
at rates which are in some cases below that which the Company is obligated to
pay and for periods less than the lease term for which the Company is obligated.
The maximum undiscounted obligation for this excess space, net of sublease
income as of December 31, 1996, assuming all break clauses in existing leases
are exercised and the Company is unable to sublet the facilities, is
approximately $16.6 million. The Company has accrued approximately $500,000 for
such excess space as of December 31, 1996, in part due to improvement in the
United Kingdom rental market and recent successes in subletting space. However,
there can be no assurance that such rental market will not be negatively
impacted in the future. See Note 12 of Notes to Consolidated Financial
Statements.
 
     The Company has had limited cash on hand to purchase equipment and internal
systems and expects to use certain proceeds from the Offering to invest in these
areas. See "Use of Proceeds."
 
     The Company believes that the net proceeds from this Offering, together
with available funds, its existing line of credit and the cash flows expected to
be generated by operations, will be sufficient to meet its anticipated cash
needs for working capital and capital expenditures for at least the next twelve
months. Thereafter, if cash generated by operations is insufficient to satisfy
the Company's liquidity requirements, the Company may, subject to adequate
market conditions, sell additional equity or debt securities or obtain
additional credit facilities. Any sale of additional securities may result in
additional dilution to the Company's stockholders.

THE COMPANY
 
     Synon is a leading provider of enterprise software application development
tools and professional services. The Company's products and services are
designed to enable its customers to develop business information software
applications through a practical model-based approach to software design.
Synon's integrated business-oriented technology provides customers the ability
to rapidly develop, deploy and enhance advanced software applications across
multiple computing platforms.
 
     Since it was founded in 1983, Synon has sold approximately 6,000 licenses
of its products to customers located in approximately 80 countries. Synon has
established development and marketing relationships with IBM's AS/400 division
for the AS/400 market and with Microsoft for the Enterprise Windows NT market.
Synon markets its products and services primarily through the Company's direct
sales force in North America, the United Kingdom, France, Italy and Australia
and through a network of distributors in Europe, Asia and Latin America.
 
INDUSTRY BACKGROUND
 
     Many organizations are responding to today's increasingly competitive
business environment by attempting to improve the efficiency and effectiveness
of information technology ("IT") processes, which has resulted in increased
demand for new business software applications. Despite large budgets and high
level management focus in many cases, IT departments often experience difficulty
rapidly deploying business critical applications, which can lead to IT backlogs.
Traditional software development and deployment methods have at times been
inadequate in meeting complex business needs in a timely manner. Third party
software can provide immediate solutions to certain business problems, but often
lacks the flexibility to meet many of the increasing complexities of today's
business and computing environments. Conversely, conventional in-house
application development can provide customized solutions, but generally requires
long development lead times and may be more prone to error.
 
     In addition, organizations seek to retain value in their software
investments by selecting software solutions that are readily adaptable to
business changes or technological advances and are portable to different
computing environments. Common examples include software changes required to
support a new product line or newly-acquired business, or enhancements of
existing systems such as those required to address the year 2000 century date
conversion problem. Traditional software solutions often fall short of
addressing the post-deployment need to enhance and maintain existing
applications.
 
     Software development tools have been designed to address the problems with
traditional software development and deployment solutions. However, certain
development tools which have allowed organizations to rapidly develop software
solutions have fallen short of addressing the complex needs of dynamic
businesses. Tools that have accelerated the development of specific departmental
applications have often lacked the power to scale to large computing
environments. Tools designed to build applications that are scalable and operate
over a wide range of environments generate applications that may not be capable
of fully utilizing the native strengths and attributes of different computing
environments. Object Oriented development technologies promise productivity
gains through the use and reuse of application building blocks, but to date
reusable objects have often lacked the size and scope necessary to provide
substantial improvements in software development.

THE SYNON SOLUTION
 
     Synon's software development products and services are designed to enable
customers to rapidly develop high-end, scalable business applications that may
be readily customized and easily maintained. Building upon a decade of
application development tools experience, the Company in late 1994 created its
Obsydian product family for the design of business critical client/server
applications for multiple computing environments. The Company believes that the
Obsydian product family offers a highly effective combination of development
speed, flexibility and quality due to the following key features:
 
     - Model-based Development: By using an application "design model" to create
       and maintain software applications, the Company's techniques enable
       software developers and end-users to more effectively define and capture,
       in an application design model, all relevant business processes,
       structures and forms at the fundamental business rule-level. Changes made
       from time to time to the application design model in response to business
       process changes will automatically ripple through the entire model to
       each relevant component.
 
     - Large-Scale Reusable Business Objects: The Company has drawn upon its
       application development experience to develop libraries of large-scale
       business objects which reflect common "patterns" found in commercial
       applications. These large, reusable business objects enable customers to
       take advantage of the efficiency of object-oriented software design
       without sacrificing the ability to adjust the software to a customer's
       specific needs.
 
     - Automated Code Generation: After the application design model is
       completed, the Company's products can automatically generate computer
       code for a variety of network environments, computing platforms and
       national languages. Synon generators produce quality code that addresses
       deployment complexity and minimizes traditional testing requirements,
       leaving the developer free to focus on the business aspects of the
       application.
 
     The combination of these technologies enables organizations to make
significant modifications to applications in rapid response to technological
advances and changes in their business environment without incurring the time
and expense required to rewrite the application. The Company's reusable business
objects are easily modified as a customer's business needs change. As a result,
the Company believes its products protect the investment in, and extend the
value of, the customers' developed applications.
 
     The Company complements the technological advantages of its software with
service offerings, including technology transfer, methodology and product
implementation, which are intended to enhance the customer's success and reduce
the customer's risk in building high-end, scalable business applications.
 
MARKET OPPORTUNITY
 
     The Company currently sells application development tools primarily in two
distinct markets: the IBM AS/400 market and the Windows NT market. According to
research estimates by International Data Corporation, there were approximately
79,000 new AS/400 systems sold in 1996, representing approximately 13% growth
over 1995, bringing the installed base to approximately 372,000 systems at
December 31, 1996. Company management estimates that approximately half of the
new AS/400 systems sold in 1996 include language compilers which the Company
considers potential customer sites. Dataquest estimates in its report dated
September 2, 1996 that the Windows NT-based application server computer systems
market will grow at a compound annual growth rate of 42% per year through 2000
and is expected to reach approximately five million systems by 1999. The Company
believes that both of these markets represent significant opportunities for its
software development products and services. To date, the Company has derived
substantially all of its revenue from application development tools and services
for the AS/400 market but believes that an increasing percentage of its sales
will come from tools and services for the Windows NT market.

STRATEGY
 
     The Company's objectives are to establish Synon as the leader in high-end
application development tools and to establish Obsydian as the leading
development framework for assembly and management of Synon- and third-party
developed large-scale business objects. Major strategies of the Company include:
 
  Capitalize on Large Customer Base and Established Market Position
 
     Synon has sold more than 6,000 licenses for its AS/400 development product,
Synon/2E, and has a large installed base of customers. Approximately 64% of
these sites are active with Synon/2E and are supported under current maintenance
agreements. When the Company introduced its next generation multi-platform
product, Obsydian, in late 1994, it first offered the AS/400 client/server
environmental generator to access the market of its large installed customer
base and to gain customer feedback and experience with the new technology.
Approximately 21% of Synon/2E customers have purchased the Obsydian product
since its introduction in late 1994. Synon intends to continue to enhance the
Synon/2E product line, while continuing to actively market Obsydian to its
Synon/2E customers.
 
     As the market leader in application development tools for the AS/400
market, the Company has been successful in acquiring approximately 300 Obsydian
customers that are new to the Company. The Company believes that there are
significant growth opportunities in the AS/400 market and plans to continue to
leverage its reputation, market position and relationship with IBM's AS/400
division to increase its penetration and market share. See "--Third Party
Relationships." Additionally, the Company intends to build, acquire or license
for resale software tools that are complementary to the Obsydian product family
such as report writers and testing tools, that will be designed to provide
increased functionality to its customers.
 
  Repeat AS/400 Success in the Emerging Windows NT Market
 
     The Company is targeting the growing market opportunity for application
development solutions in the emerging Windows NT operating environment. Synon
has developed an Obsydian Enterprise NT environmental generator which provides
the same application development value in the NT environment as in the AS/400
environment. The generator, which became generally available in March 1997,
automatically generates applications which are compliant with Microsoft's NT
Back Office application standards. Existing Synon customers who have already
developed applications using the Obsydian product can automatically regenerate
those applications to operate natively on platforms supported by Windows NT.
Synon plans to aggressively market the product to existing customers, especially
ISVs desiring rapid access to the Windows NT marketplace with existing
Obsydian-based products, and to large companies adopting the Windows NT
operating environment. The Company believes that its experience and success in
the AS/400 market and its relationship with Microsoft make it well positioned to
become a leading provider of application development solutions in this rapidly
expanding market. See "-- Third Party Relationships."
 
  Capitalize on IBM and Microsoft Relationships
 
     Synon has established development, marketing and distribution relationships
with IBM's AS/400 division and Microsoft. The Company has had a long-standing
relationship with IBM's AS/400 division and currently participates in several of
IBM's AS/400 division marketing programs worldwide and maintains close ties with
its AS/400 product development organizations. Additionally, CGI Informatik GmbH,
an IBM subsidiary, acts as the primary distributor of the Company's products in
Germany. In 1996, IBM's AS/400 division sponsored a joint development lab to
encourage the building of large Obsydian-enabled business objects by IBM, Synon
and their customers in order to accelerate the availability of a wider range of
reusable business objects. In January 1997, IBM and Synon jointly announced the
availability of the first products developed in this lab, business objects that
enable integration with Lotus Domino applications. See "Risk Factors--Dependence
on Relationships with IBM and Microsoft," "--Third Party Relationships" and
"Certain Transactions--Agreements with IBM."

<PAGE>   34
 
     Synon has established a strong working relationship with Microsoft that
Synon believes is important to its future success in the Windows NT market. A
number of agreements with Microsoft have served as the basis for this
relationship. In 1996, Microsoft and the Company entered into an agreement to
facilitate the development of the Windows NT generator. Microsoft and Synon are
also currently parties to a Co-Sponsorship Agreement pursuant to which, in
exchange for payment of a fee, Synon was Co-Sponsor of Microsoft Tech Ed 1997,
with certain joint advertising exposure opportunities and related benefits.
Synon also co-sponsored Microsoft's annual Professional Developers' Conference
in November 1996. In addition, Synon and Microsoft are parties to a Memorandum
of Understanding pursuant to which Synon has agreed, among other things, to
train and certify product specialists on Windows NT and SQL Server, to train
representatives and channel partners on BackOffice product marketing and to
provide Microsoft's ChannelBase mailing information for joint selling
opportunities. Synon also participates in certain Microsoft promotional programs
and jointly prepares related marketing and promotional materials. Synon intends
to continue to work with Microsoft in the future on these and related projects.
See "Risk Factors--Dependence on Relationships with IBM and Microsoft" and
"--Third Party Relationships."
 
  Build Upon Technological Leadership
 
     The Company has developed a number of advanced technologies designed to
create enterprise-scale business critical client/server applications. As an
industry leader in model-based application development tools, the Company has
continued to extend its technology leadership in object-oriented patterns and
high performance, optimized application generators. The Company plans to extend
Obsydian and its repository to become a development vehicle for combining and
delivering large-scale business objects from multiple vendors into fully
functioning applications. The Company plans to leverage these technologies to
make it easier and faster to create large-scale applications that are flexible
and easy to customize. The Company intends to commit substantial resources to
maintain and extend its technological leadership.
 
  Facilitate Technology Adoption and Use
 
     The Company's enterprise application development software tools are
sophisticated, high-end products. As with all complex software products,
substantial investment of time and resources is required for users to become
educated and fluid with these products. Synon's in-house professional services
organization assists customers in technology transfer and application
development and deployment. The Company encourages independent consulting firms
to promote the growth of its Obsydian product. The Company has recently
developed the Flyte series of consulting services offerings which it markets to
its customers. Synon plans to continue to offer a range of professional services
to facilitate the successful implementation of applications developed using
Synon products. See "--Third Party Relationships."
 
     Reusable business objects are central to the development power of Obsydian.
The Company plans to continue building libraries of reusable business objects
for resale and provide a channel for the resale of objects developed by third
parties. The Company intends to focus its efforts, in concert with those of
certain of its customers, on the development of a range of vertical industry
object libraries. The Company believes that a market is emerging for the
development and sale of libraries of reusable business objects which may provide
additional advantages to Synon customers.
 
  Leverage Worldwide Presence
 
     Synon has an established direct sales force and a network of distributors
in major markets of the world. Each sales channel has customer support and
professional service capabilities, which the Company believes represents a
competitive advantage in marketing its products and provides a platform for
expansion as market opportunities arise.

TECHNOLOGY AND PRODUCTS
 
     Synon's development products are designed to produce large, scalable,
business applications. They incorporate the knowledge gained from over a decade
of application development tools experience. The keys to successful development
of large applications are the speed with which they can be developed, and the
ease of customization after they are complete. Synon's technology represents a
highly productive combination of speed and flexibility.
 
     OBSYDIAN TECHNOLOGIES
 
     Integrated Repository. All Obsydian development facilities, such as the
Diagram Model Editor and the Class Libraries, are directly linked to a central
integrated repository. Changes made while using any tool component, at any point
in the development cycle instantly update all related elements of the model and
are clearly visible from any other facility or point of view.
 
     The repository tracks all design information in three deployment dimensions
with a full audit trail: version, platform, and national language. As new design
information is added to an application, it is stored separately from the
existing design. This means it is possible to view and create the application as
it exists in different releases of the software, as it appears in different
national languages, or as implemented on to different platforms. Software
vendors can create versions of their application that vary according to
customization done for specific customers or countries, and retain knowledge at
the lowest level of detail on how the customizations differ from their base
product.
 
     The Obsydian repository is a distributed repository. Accordingly, objects
in one repository can inherit traits from objects in a different repository.
This enables Synon to build and maintain class libraries of objects which can be
sold and distributed for use and extension by others.
 
     The greatest advantage of a repository based system is the preservation of
the application design in the face of continual technological change. An
existing design can be deployed on new platforms as generators become available.
For example, a software vendor that has created an application with a Windows
client and AS/400 server instantly gains access to the Windows NT server market
with the availability of the Company's Windows NT generator. Windows NT Back
Office programming is complex. It demands knowledge of Windows NT processes, the
Registries, security architecture, integration with Microsoft System Management
Services and Microsoft Mail, and database optimization for SQL Server. The task
of learning a new platform and porting an application could take months or
years. However, because the Synon generator shields the developer from needing
to understand the new technology, the task can be accomplished in days of
generator availability.
 
     Patterns. Reusable business objects ("patterns") reflect common business
structures and behaviors which are found in many commercial applications. Synon
technology resolves the inherent conflict between the desire to use large
reusable development objects for efficiency and the difficulty of modifying them
to address a specific customer's needs. Abstract or generic pattern definitions
are merged with the application context or specific characteristics of the
business to create the final application. Patterns describing the
interrelationships of many software components -- such as screens, events,
reports, methods, tables, views, messages and even help text -- can be described
in detail and may represent over one hundred programs of quality pretested code.
The size of patterns which can be created with Synon technology extends all the
way to fully functioning vertical applications. If a pattern achieves only 90%
of the desired behavior, the developer can "replace" the undesired 10% with
alternative behavior.
 
     As an example, a common pattern may be used to create apparently unrelated
application business objects such as a purchase order, an insurance policy, or a
utility bill. Because each of these objects is composed of detail line items and
headers (structure) and share standard processing logic (behavior), a common
pattern (abstraction) can be defined. The abstract definitions can be extensive:
database tables and views describing the header/footer relationship, totaling
algorithms, printing routines, screens
 
                                       34
<PAGE>   36
 
for viewing the objects and screens for managing transactions. Even the simplest
pattern results in the creation of dozens of executable objects.
 
     [Picture of utility bill, insurance policy and purchase order]
 
     Synon's pattern technology merges the specific characteristics of objects
such as orders, policies or utility bills into the generic pattern. The result
is the complete creation of a subsystem at a fraction of the effort to build
these application business objects by traditional methods. Further, if either
the pattern or the specific added elements change, the application is
automatically re-implemented to behave with the new rules.
 
     Synon's pattern technology can incorporate components from the growing
third party component market. Components today are often graphic controls such
as "sliders" and "fuel gauges". Some are sophisticated controls with which
business data can be viewed in a variety of charts and graphs. These components
can be inserted into patterns created with Synon technology, allowing Obsydian
users broader access to third party generated patterns.
 
     In addition to the patterns provided with Obsydian, developers using Synon
technology can build their own reusable patterns. These patterns range from
patterns for automatically integrating third-party technologies, such as the
pattern for the Lotus Domino groupware application, to general purpose or
specific vertical industry patterns.
 
     Environmental Generators. When a design is complete, program generators
take relevant information from the repository and automatically create the
application's programs. The Company's products currently support the following
platforms: C++ applications on Windows, Windows NT and UNIX platforms, and RPG
on the AS/400. The programs are generated in the native language of the platform
on which the application will be executing to exploit the unique advantages and
features of each platform. This provides applications optimized for each
environment. The Company is currently developing a Java generator to add greater
flexibility in deployment options.
 
     [Picture of repository, generator and 3GL application.]
 
     The separation of design from implementation provides many advantages.
First, a single design can be generated to execute in different environments.
Simply regenerating will create the same application on AS/400, Windows NT or
UNIX. This saves the time and complexity of having to port a completed
application from one environment to another.
 
                                       35
<PAGE>   37
 
     Another benefit of the environmental generators is that they can shield the
developer from the technical intricacies of each target platform, leaving the
developer free to focus on the business view of the application. For example,
the techniques required to successfully build a client/server application are
complex. Communications programming, record buffering for optimization,
character type translation and code page translation all need to be considered.
Each of these considerations can vary by platform. However, the Synon generators
automatically generate code that deals with deployment complexity.
 
     Application Partitioning. The flexibility of deployment extends to network
topology as well as platform. The screen handling code can run on the client
machine, database operations on the database server and business processing on
any number of other servers. Synon generators allow a single application to be
partitioned and deployed to any number of different platforms. The partitioning
of logic between clients and servers can occur at design time, at deployment
time, or dynamically at runtime. Runtime deployment means that an application
can load-balance by redirecting program calls from one server to another as the
traffic on the network changes. It also means that applications designed to run
in a client/server mode can also run detached from the network. For example, an
application can run entirely on a laptop, but when connected to the network
cease to invoke programs on the laptop and instead call programs on a server.

currently ranging from $2,000 to $4,000. Volume discounts are applied to these
list prices and are approximately 30% for a ten seat purchase. Annual customer
support and upgrade fees are priced separately at approximately $6,000 per site
and 10% of the per seat product list price, respectively.
 
     SYNON/2E TECHNOLOGIES
 
     Synon/2E is a robust development environment for creating AS/400 server
centric applications. Many of the technology features provided in Obsydian have
their roots in Synon/2E. Synon/2E applications are stored in a fully integrated
repository. As a result, Synon/2E customers can with relatively limited effort
solve year 2000 problems in their existing applications that were developed
using Synon/2E. Because the repository knows where all dates are used, changing
a date definition in a single location and regenerating the application will
automatically update all dates (including those used in screens, reports,
program logic, etc.) to recognize the century. Through impact analysis, the
customer can easily verify all the logic relating to the changed date fields. A
problem that could take months or years to solve becomes simply a deployment
exercise.
 
     The Synon/2E generators create RPG or COBOL programs for optimal
performance on the AS/400. As new AS/400 technologies emerge, Synon/2E customers
will be able to reimplement their existing applications. For example, a new
generator will create Internet applications through Java, so legacy "dumb
terminal" AS/400 applications can be regenerated to become accessible as GUI
applications through the Internet.
 
     The precursor to Obsydian's pattern technology are the program templates
available in Synon/2E. These templates are program skeletons that reflect
well-tested programming practices for creating AS/400 screen, report, and batch
programs. By allowing developers to place their business logic into the
templates, Synon produces consistent, high quality programs much faster than
would be possible through traditional methods.
 
     SYNON/2E PRODUCT FAMILY
 
     Synon/2E Development Environment: Using data modeling techniques to express
     relationships and business rules, along with high-level action diagrams to
     describe process logic for complex interactive, batch, and reporting
     processes, Synon/2E speeds implementation of the design model with
     COBOL/RPG code generation for the AS/400.
 
     Synon/PE: Analyzes design models to maximize performance.
 
     Synon/RPM: An adaptation of the rapid application development methodology.
 
     Synon Model Applications (SMA) -- Financial: An integrated financial
     accounting system designed by Synon using Synon/2E.
 
     Third Party Products: Graphical modeling facility, change management and
     report writing.
 
     Each Synon/2E family product is priced per customer central processing unit
("CPU") on which such product operates, with higher prices for CPU's with
relatively greater computing capacity. Synon/2E prices range from approximately
$48,000 to $104,000 depending on the CPU, with additional generators ranging
from $12,000 to $26,000 depending on the CPU. The SMA Financial application is
priced from approximately $50,000 to $360,000. Maintenance agreements for the
Synon/2E product family are typically priced at 15% of the list price of the
license annually.
 
     PROFESSIONAL SERVICES AND CUSTOMER SUPPORT
 
     Synon provides a broad range of customized and packaged professional

   <S>                    <C>
   REQUIREMENT..........  Amway needed to build and deploy major new inventory, order
                          management and custom remittance applications to be used in
                          approximately 30 countries to support its worldwide growth
                          strategy while concurrently standardizing the processes and
                          systems among its affiliates.
   SYNON'S SOLUTION.....  Using Synon/2E, Amway headquarters IT staff developed core sets of
                          application models which were distributed to local country IT
                          staffs for customization and implementation.
   BENEFITS.............  The core models were designed to be easily modified by local IT
                          staffs to accommodate country variances and ongoing needs. In
                          addition, the staff in each country is able to use the
                          headquarters' model, incorporate headquarters' updates and
                          automatically create the same application in the local national
                          language. Utilizing the Synon/2E product, Amway's IT function

   A leading multinational reinsurance underwriter and subsidiary of
   Switzerland-based Zurich Insurance.
 
<TABLE>
   <S>                    <C>
   REQUIREMENT..........  Zurich Re needed to identify a strategic tool to rewrite its core
                          underwriting support systems. This was part of a business process
                          review, demanded by changing business needs and the requirement to
                          improve customer service. The first key module of this scalable
                          enterprise application was a Contact Management System.
   SYNON'S SOLUTION.....  Using Obsydian's model-based environment with the AS/400 and Win-
                          dows/NT generators, Zurich Re was able to rapidly build a complex
                          application that exploited the latest system vendor technologies.
   BENEFITS.............  Zurich Re was able to complete the core functionality of this
                          system in 3.5 months. Using a third generation language
                          programming approach, this project would have taken considerably
                          longer. The combination of Obsydian technology and the Company's
                          consulting guidance helped Zurich Re rapidly build a sophisticated
                          and comprehensive front-line Contact Management System, an
                          integral part of their underwriting business and strategic plans.

  POLICY MANAGEMENT SYSTEMS CORPORATION ("PMSC")
 
   One of the largest providers of software and services for the insurance
   industry.
 
<TABLE>
   <S>                    <C>
   REQUIREMENT..........  Create a new release of its client/server, multi-platform
                          application for midsize companies.
   SYNON'S SOLUTION.....  PMSC used Obsydian technology to build its POINT Open application,
                          a Property and Casualty Insurance solution. The POINT system
                          consists of fully integrated components which include Policy
                          Administration, Rating, Claims, Billing and Collection, Payables,
                          and Reinsurance.
   BENEFITS.............  With Obsydian, PMSC has realized benefits through Object Oriented
                          software design and reusability. Rating and Policy Processing, the
                          first business function of POINT Open developed with Obsydian, is
                          a comprehensive 4 million plus lines of code component. The effort
                          to develop the second component, Claims, took advantage of many of
                          the pre-built classes. Although the Claims component was 16% the
                          size of the Rating and Policy Processing, it took only 8.5% of the
                          effort.

THIRD PARTY RELATIONSHIPS
 
  IBM Corporation
 
     Synon has had a long-standing relationship with IBM which solidified with
the introduction of the AS/400 in 1988. The Company currently participates in
several of IBM's AS/400 division marketing programs worldwide and maintains
close ties with its AS/400 division product development organizations.
Additionally, CGI Informatik GmbH, a subsidiary of IBM, acts as a primary
distributor of the Company's products in Germany.
 
     The Company and IBM's AS/400 division have engaged in several joint
development or sponsored development projects in the past aimed at accelerating
availability of Synon products compatible with IBM's AS/400 division offerings.
In 1996, IBM's AS/400 division sponsored a joint development lab to encourage
the building of large Obsydian-enabled business objects by IBM, Synon and their
customers in order to accelerate the availability of a wider range of reusable
business objects. Currently, IBM's AS/400 division and Synon are jointly
participating in the development of large business object class libraries
 
                                       41
<PAGE>   43
 
which can be assembled and deployed through Obsydian. The first libraries
produced by the joint work are the Lotus Notes Class Library and the AS/400 FAX
Class Library. See "--Technology and Products." Both companies are encouraging
third parties to participate in the development lab to build industry vertical
and other reusable class libraries.
 
     In 1992, IBM purchased 1,666,667 (pre-conversion) shares of the Company's
Series E Preferred Stock for $5 million. The Series E Preferred Stock will be
converted to 833,333 shares of Common Stock upon closing of the Offering. See
"Certain Transactions -- Preferred Stock Sales," "Principal and Selling
Stockholders" and Note 2 of Notes to Consolidated Financial Statements.
 
  Microsoft Corporation
 
     Synon has established a strong working relationship with Microsoft that
Synon believes is important to its future success in the Windows NT market. A
number of agreements with Microsoft have served as the basis for this
relationship. In 1996, Microsoft and the Company entered into an agreement to
facilitate the development of the Windows NT generator. Microsoft and Synon are
also currently parties to a Co-Sponsorship Agreement pursuant to which, in
exchange for payment of a fee, Synon was Co-Sponsor of Microsoft Tech Ed 1997,
with certain joint advertising exposure opportunities and related benefits.
Synon also co-sponsored Microsoft's annual Professional Developers' Conference
in November 1996. In addition, Synon and Microsoft are parties to a Memorandum
of Understanding pursuant to which Synon has agreed, among other things, to
train and certify product specialists on Windows NT and SQL Server, to train
representatives and channel partners on BackOffice product marketing and to
provide Microsoft's ChannelBase mailing information for joint selling
opportunities. Synon also participates in certain Microsoft promotional programs
and jointly prepares related marketing and promotional materials. Synon intends
to continue to work with Microsoft in the future on these and related projects.
See "Risk Factors-- Dependence on Relationships with IBM and Microsoft."
 
SALES AND MARKETING
 
     The Company markets and sells its products and services through its direct
sales force in the U.S., Canada, United Kingdom, France, Italy and Australia and
through a network of distributors in the rest of Europe, Asia and Latin America.
The Company distributes its products in Asia and Italy through joint venture
arrangements pursuant to which Synon owns 51% of the distributor located in
Japan, 65% of the distributor located in Italy and 75% of the distributor
located in Hong Kong. In addition, CGI Informatik GmbH, a subsidiary of IBM, is
the Company's primary distributor in Germany. Through both the direct sales and
distributor channels, the Company employs an integrated solution approach to
selling which combines its product offerings with professional services. In
addition, the Company is developing its indirect channels to complement direct
sales in its major markets.
 
     Synon's marketing functions provide a comprehensive range of programs and
activities intended to broaden the worldwide market appeal for its products and
services and to support the direct sales channels employed by the Company. Each
of the Company's distributors provides a range of marketing programs to support
their selling efforts which often utilize marketing materials prepared by the
Company. Marketing activities include participation in major trade shows and
industry forums, public relations campaigns, advertising, product seminars,
telemarketing, newsletters, direct mailings, and preparation of a variety of
sales collateral materials. The Company also participates with IBM and Microsoft
in joint marketing programs and intends to seek continued opportunities to work
with both companies. See "--Third Party Relationships."
 
     The Company has entered into agreements with ISVs to help promote and sell
the Company's products. The agreements fall into three general categories, OEM,
Reseller and Cooperative Marketing. The Company has one OEM agreement with the
Marcam Corporation under which Marcam sells a customized version of the
SMA/Financials product to its end user customers and has rights to sell Synon/2E
to those same customers. The Company has entered into reseller agreements with
Policy Management Corporation and American Software USA, Inc. under which the
companies have the right to
 
                                       42
<PAGE>   44
 
sell special versions of the Company's products to customize, enhance or
maintain the software products which were developed by these resellers using
Synon products. Additionally, the Company has entered into cooperative marketing
agreements with many of its ISV customers under which the companies are paid a
finder's fee for their assistance in providing sales leads and helping in
product sales process.
 
PRODUCT DEVELOPMENT
 
     The Company is currently focusing development efforts on various
enhancements to Obsydian, including a 32 bit tool, ActiveX capabilities,
external class definition capabilities, open repository capabilities and change
management capabilities. Pursuant to an agreement with IBM's AS/400 division,
the Company is also developing a Java language code generator. See "Certain
Transactions."
 
     Synon has made substantial investments in new technologies and product
development. The Company believes that its future success will depend in large
part on its ability to enhance existing products, introduce new technologies and
develop new products which meet the needs of a rapidly changing application
development marketplace. As of March 31, 1997, the Company's research and
development staff consisted of 85 employees located principally at its
headquarters in Larkspur, California with a smaller development team in London,
England. Synon's research and development expenses (after capitalization of
software development costs) were approximately $4.1 million, $4.9 million, and
$5.9 million for 1994, 1995 and 1996, respectively.
 
     The Company's product development organization is responsible for product
architecture, core technology and functionality, product testing, user interface
development and expansion of the ability of Obsydian to operate with leading
hardware platforms, operating systems, relational database management systems
and networking and communication protocols. This organization is also
responsible for new product development. Central to the Company's development
approach is concurrent engineering by small product teams. Each group is focused
on development of independent software components within a disciplined set of
protocols so that, when assembled, the components interact and communicate
properly. This approach enables the Company to manage the overall development
process in incremental elements and to track performance, identify problem areas
and add additional resources where necessary. The Company also maintains
detailed release planning procedures to ensure integration, testing and version
control among different groups developing a single release.
 
     The market for the Company's products is subject to rapid technological
change, changing customer needs, frequent new product introductions and evolving
industry standards that may render existing products and services obsolete. As a
result, the Company's position in its existing markets or other markets that it
may enter could be eroded rapidly by product advances. Synon's vulnerability to
rapid technological change and changing customer needs is heightened by the
focus of its product development efforts on the Obsydian product line and
Obsydian for the Windows NT computing platform. See "Risk Factors--Rapid
Technological Change; Product Development Risks."
 
COMPETITION
 
     The software development market is highly fragmented and serviced by many
firms. The market for advanced software used in the development, deployment and
management of high-end client/server application software systems is intensely
competitive and characterized by rapidly changing technology, evolving industry
standards, frequent new product introductions and rapidly changing customer
requirements. The Company's development tools are targeted primarily at
developers of large business applications running on the Windows NT operating
platform and the AS/400. In the market for high-end client/server application
development software tools, the Company expects to compete primarily with Forte
Software, Inc. and Texas Instruments Incorporated with respect to users of the
Windows NT operating platform, and currently competes primarily with Progress
Software Corporation and several small software companies with respect to users
of the AS/400. In the market for less complex client/server application
development software tools, the Company competes primarily with Powersoft
Corporation, IBM's Visual Age product line and Microsoft's Visual Basic with
respect to users of the
 
                                       43

Windows NT operating platform and with IBM's Visual Age product line with
respect to users of the AS/400.
 
     Software that can be developed and deployed using the Company's Obsydian
environment can also be implemented using a combination of first generation
application development tools and more powerful server programming techniques
such as stored procedures in relational databases, C or C++ programming, and
networking and database middleware to connect the various components.
Consequently, the Company experiences competition from potential customers'
decisions to pursue this approach as opposed to utilizing an application
environment such as Obsydian. Similarly, the Company's products compete against
the alternative of conventional software development in the AS/400's native RPG
language. As a result, the Company must continuously educate existing and
prospective customers as to the advantages of the Company's products. There can
be no assurance that these customers or potential customers will perceive
sufficient value in the Company's products to justify purchasing them.
 
     The Company also competes with database vendors such as Oracle, Informix
and others that offer their own development tools for use with their databases.
The Company may in the future face additional direct or indirect competition
from IBM or Microsoft in the event that such companies continue to develop their
own application development tools for the AS/400, Windows NT or other computing
platforms or enter into strategic relationships with any of the Company's
competitors. In addition, since the software industry has relatively low
barriers to entry, the Company may in the future face additional competition
from start-up companies or others in the software application development tool
industry.
 
     Most of the Company's current competitors have, and future competitors may
have, significantly greater financial, technical, marketing and other resources
than the Company. The Company's competitors may be able to respond more quickly
to new or emerging technologies and changes in customer requirements or devote
greater resources to the development, promotion and sale of their products than
the Company. Also, most current and potential competitors have greater name
recognition and more extensive customer bases that could be leveraged, thereby
gaining market share to the Company's detriment. The Company expects to face
additional competition as other established and emerging companies enter the
application development tools market and new products and technologies are
introduced. Increased competition could result in price reductions, reduced
purchases of licenses, professional services and maintenance, lower gross
margins or loss of market share, any of which would materially adversely affect
the Company's business, operating results and financial condition.
 
     In addition, current and potential competitors have established or may
establish cooperative relationships among themselves or with third parties or
make strategic acquisitions to increase the ability of their products to address
the needs of the Company's prospective customers. Accordingly, it is possible
that new competitors or alliances among current and new competitors may emerge
and rapidly acquire significant market share. There can be no assurance that the
Company will be able to compete successfully against current and future
competitors or that competitive pressures faced by the Company will not
materially adversely affect its business, operating results and financial
condition. Further, there can be no assurance that products or technologies
developed by others will not render the Company's products noncompetitive or
obsolete. In addition, regardless of the Company's success in the marketplace, a
negative perception of the Company generated by industry analysts or the public
more generally could detract from the Company's competitiveness. See "Risk
Factors -- Competition."
 
     The principal competitive factors affecting the market for the Obsydian and
Synon/2E product families are ease of application development, functionality and
features, product architecture, product performance, reliability and
scaleability, product quality, price and customer support. The Company believes
it presently competes favorably with respect to each of these factors. However,
the Company's market is still evolving and there can be no assurance that the
Company will be able to compete successfully against current and future
competitors and the failure to do so successfully will have a material adverse
effect upon the Company's business, operating results and financial condition.

INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
     The Company's success is heavily dependent upon proprietary technology. The
Company also believes that factors such as the technological and creative skills
of its personnel, new product developments, frequent product enhancements, name
recognition and reliable product maintenance are essential to establishing and
maintaining a technology leadership position. The Company relies primarily on a
combination of copyright and trademark laws, trade secrets, confidentiality
procedures and contractual provisions to protect its proprietary rights. The
Company seeks to protect its software, documentation and other written materials
under trade secret and copyright laws, which afford only limited protection. The
Company presently has no patents or patent applications pending. Despite
precautions taken by the Company, it may be possible for unauthorized third
parties to copy aspects of its products or future products or to obtain and use
information that the Company regards as proprietary. In particular, for the SMA
financial product and class libraries, the Company provides its licensees with
access to its data model and other proprietary information underlying its
licensed applications. There can be no assurance that the Company's means of
protecting its proprietary rights now or in the future will be adequate or that
the Company's competitors will not independently develop similar or superior
technology. Litigation may be necessary in the future to enforce the Company's
intellectual property rights, to protect the Company's trade secrets or to
determine the validity and scope of the proprietary rights of others. Such
litigation could result in substantial costs and diversion of resources and
could have a material adverse effect on the Company's business, operating
results and financial condition.
 
     The Company, Dysys, and Simon Williams and Melinda Horton, founders and
major stockholders of the Company, are parties to the Dysys Agreement in
connection with which the Company acquired from Dysys certain intellectual
property which was included in the Company's Obsydian product. In connection
with the Dysys Agreement, the Company currently incurs a liability to pay Mr.
Williams and Ms. Horton a 1% and 0.5% royalty, respectively, on Obsydian license
and maintenance revenue on transactions entered into through June 30, 1999.
Pursuant to the Dysys Agreement, Mr. Williams and Ms. Horton also retain certain
rights with respect to the intellectual property, including the non-exclusive
right to use and exploit it under certain circumstances, including the Company's
failure to pay required royalty amounts in connection with the Dysys Agreement
and of certain other occurrences. See "Certain Transactions -- Dysys Agreement."
 
     Policing unauthorized use of the Company's software is difficult, and,
while the Company does not believe software piracy is a significant problem to
the Company at present, there can be no assurance that it will not become a
problem in the future. In addition, the laws of some foreign countries do not
protect the Company's proprietary rights to the same extent as do the laws of
the United States. The Company is not aware that any of its software product
offerings infringe the proprietary rights of third parties, but there can be no
assurance that third parties will not claim infringement by the Company with
respect to current or future products. The Company expects that software
developers will increasingly be subject to infringement claims as the number of
products and competitors in the Company's industry segment grows and the
functionality of products in different industry segments overlaps. Any such
claims, with or without merit, could be time-consuming, result in costly
litigation, cause product shipment delays or require the Company to enter into
royalty or licensing agreements. Such royalty or licensing agreements, if
required, may not be available on terms acceptable to the Company or at all,
which could have a material adverse effect on the Company's business, operating
results and financial condition. Any such delays or reductions in product
shipments could materially and adversely affect the Company's business,
operating results and financial condition. See "Risk Factors -- Dependence on
Proprietary Rights and Technology; Risk of Infringement."
 
EMPLOYEES
 
     As of March 31, 1997, the Company had a total of 488 employees, including
85 in product development, 48 in customer support, 104 in sales and marketing,
181 in professional services, and 70 in finance and administration. Of these
employees 324 were located in the United States and Canada, 132 located in
Europe and 30 in Australia and Japan. None of the Company's employees is
represented by a
 
                                       45
<PAGE>   47
 
collective bargaining agreement and the Company has never experienced a work
stoppage. The Company considers its relations with its employees to be good.
 
     The Company believes its future success depends in large part on its
ability to attract and retain qualified employees, especially highly skilled
product developers, customer support professionals and professional services
consultants and capable direct sales and pre-sales support representatives.
There can be no assurance that the Company will be successful in retaining,
recruiting or training key personnel. Failure to attract and retain key
personnel could have a material adverse effect on the Company's business,
operating results and financial condition.
 
FACILITIES
 
     Synon's headquarters are located in Larkspur, California in a 42,675 square
foot facility under leases which expire December 1999 through May 2001. The
Larkspur facility houses the primary product development, customer support,
marketing, finance and administration and executive management of the Company.
The Company also occupies 19,789 square feet of facilities in London under
various lease agreements expiring January 1998 to December 2014. Additionally,
the Company leases space for sales and support facilities in a variety of
international and domestic locations including White Plains, New York and the
metropolitan areas of Chicago, Dallas, Atlanta, Los Angeles, Seattle, Paris,
Milan, Sydney, Melbourne, and Tokyo. The Company believes that its existing
facilities and offices will be adequate at least through the end of the year and
that sufficient additional space will be available as needed thereafter.
 
     The Company has approximately 34,000 square feet in excess facilities in
the United Kingdom under long term lease agreements expiring December 1999
through December 2014. These facilities are currently subleased to third parties
at rates which are in some cases below that which the Company is obligated to
pay and for periods less than the lease term for which the Company is obligated.

<PAGE>   50
 
     The Company's 1997 Director Option Plan (the "Director Plan") provides that
options will be granted to non-employee directors ("Outside Directors"),
pursuant to an automatic nondiscretionary grant mechanism. The Director Plan
provides for an initial grant of options to purchase        shares of Common
Stock to each Outside Director upon the later of the effective date of the
Director Plan or the date on which such individual first becomes an Outside
Director. In addition, each Outside Director will subsequently be granted an
option to purchase 5,000 shares of Common Stock at the first meeting of the
Board of Directors following the annual meeting of stockholders in each year
beginning with the 1997 Annual Meeting of Stockholders if on such date, such
Outside Director has served on the Board of Directors for at least six months.
Each option under the Director Plan will be granted at the fair market value of
the Common Stock on the date of grant and will become exercisable over four
years, with 25% of the shares vesting after one year and the remaining shares
vesting in equal monthly installments thereafter. See "Stock Plans -- 1997
Director Option Plan."

(1) Based on an aggregate 371,250 shares subject to options granted to employees
    of the Company and its subsidiaries during 1996.
 
(2) Options were granted at an exercise price equal to the fair market value of
    the Company's Common Stock on the date of grant, as determined by the Board
    of Directors.
 
(3) Exercise price may be paid in cash, by check, or at the discretion of the
    Board, by promissory note or such other consideration and method of payment
    permitted by applicable law.
 
(4) The term of each option granted under the 1990 Stock Option Plan is
    generally ten years from the date of grant. Options may terminate prior to
    their expiration dates, however, if the optionee's continuous status as an
    employee is terminated or upon the optionee's death or disability. Options
    granted under the 1990 Stock Option Plan generally must be exercised within
    ninety (90) days of the termination of the optionee's status as an employee,
    or within twelve (12) months after such optionee's death or disability.
 
(5) Potential realizable value is based on the assumption that the Common Stock
    of the Company appreciates at the annual rate shown (compounded annually)
    from the date of grant until the expiration of the ten year option term.
    These numbers are calculated based on the regulations promulgated by the
    Securities and Exchange Commission and do not reflect the Company's estimate
    of future stock price growth.

STOCK PLANS
 
     1990 Stock Option Plan. The Company's 1990 Stock Option Plan (the "1990
Plan") provides for the grant of incentive stock options within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), and
the nonstatutory stock options to employees of the Company. As of March 31,
1997, options to purchase an aggregate of 1,347,930 shares of Common Stock were
outstanding under the 1990 Plan, with a weighted average exercise price of
$3.16. Subsequent to March 31, 1997, the Board of Directors granted options to
purchase 6,000 shares of Common Stock under the 1990 Plan. The Board of
Directors has determined that no further options will be granted under the 1990
Plan after this Offering. The 1990 Plan provides that in the event of a merger
of the Company with or into another corporation, each outstanding option will be
assumed or substituted for by the successor corporation. In the event the
successor corporation refuses to assume or substitute for the option, the
optionee shall have the right to exercise all shares subject to the option,
including shares as to which it would not otherwise be exercisable.
 
     Executive Share Option Scheme. The Company's Executive Share Option Scheme
(the "Executive Scheme") provides for the grant of nonstatutory stock options to
full-time employees and directors of the Company or any of its subsidiaries. As
of March 31, 1997, options to purchase an aggregate of 18,800 shares of Common
Stock were outstanding under the Executive Scheme with a weighted average
exercise price of $3.34. Since March 31, 1997, the Board of Directors has not
granted any further options to purchase shares of Common Stock under the
Executive Scheme. The Board of Directors has determined that no further options
will be granted under the Executive Scheme after this Offering.
 
     1997 Incentive Stock Option Plan. The Company's 1997 Incentive Stock Option
Plan (the "1997 Plan") provides for the grant to employees of incentive stock
options within the meaning of Section 422 of the Code, and for the grant to
employees, directors and consultants of nonstatutory stock options and stock
purchase rights. The 1997 Plan was adopted by the Board of Directors in May 1997
and approved by the Company's stockholders in           1997. The 1997 Plan
replaces the 1990 Plan and the Executive Scheme. However, options previously
issued under the 1990 Plan and the Executive Scheme shall continue to be
exercisable according to their terms. Unless terminated sooner, the 1997 Plan
will terminate automatically in May 2007. A total of 1,500,000 shares of Common
Stock, plus annual increases equal to the lowest of (i) 400,000 shares of Common
Stock, (ii) 3% of the outstanding shares
 
                                       51
<PAGE>   53
 
of Common Stock or (iii) a lesser amount determined by the Board of Directors
has been reserved for issuance under the 1997 Plan.
 
     The 1997 Plan may be administered by the Board of Directors or by a
committee of the Board (the "Committee"), which Committee shall, in the case of
options intended to qualify as "performance-based compensation" within the
meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"), consist of two or more "outside directors" within the meaning of
Section 162(m) of the Code. The Committee has the power to determine the terms
of options granted, including the exercise price, number of shares subject to
the option, the exercisability thereof, and the form of consideration payable
upon such exercise. In addition, the Committee has the authority to amend,
suspend or terminate the 1997 Plan, provided that no such action may affect any
share of Common Stock previously issued and sold or any option previously
granted under the 1997 Plan.
 
     Options and stock purchase rights granted under the 1997 Plan are not
generally transferable by the optionee, and each option and stock purchase right
is generally exercisable during the lifetime of the optionee only by such
optionee. Options granted under the 1997 Plan must generally be exercised within
three months following termination of an optionee's status as an employee,
director or consultant of the Company, within twelve months after an optionee's
termination by disability, and within twelve months after an optionee's
termination by death, but in no event later than the expiration of the option.
In the case of stock purchase rights, unless the administrator determines
otherwise, a restricted stock purchase agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's employment with the Company for any reason (including death or
disability). The purchase price for shares repurchased pursuant to a restricted
stock purchase agreement shall be the original price paid by the purchaser and
may be paid by cancellation of any indebtedness of the purchaser to the Company.
The repurchase option shall lapse at a rate determined by the administrator. The
exercise price of all incentive stock options granted under the 1997 Plan must
be at least equal to the fair market value of the shares on the date of grant.
The exercise price of nonstatutory stock options granted under the 1997 Plan is
determined by the Committee, but with respect to nonstatutory stock options
intended to qualify as "performance-based compensation" within the meaning of
Section 162(m) of the Code, the exercise price must be at least equal to the
fair market value of the Common Stock on the date of grant. With respect to any
employee who owns stock possessing more than ten percent of the voting power of
all classes of the Company's outstanding capital stock, the exercise price of
any incentive stock option granted to such person must equal at least 110% of
the fair market value of the Common Stock on the date of grant and the term of
such incentive stock option must not exceed five years. The term of all other
options granted under the 1997 Plan may not exceed ten years.
 
     The 1997 Plan provides that in the event of a merger of the Company with or
into another corporation, or a sale of substantially all of the Company's
assets, each outstanding option and stock purchase right will be assumed or
substituted for by the successor corporation. In the event the successor
corporation refuses to assume or substitute for the option or stock purchase
right, the optionee shall have the right to exercise all of the optioned stock,
including shares as to which it would not otherwise be exercisable.
 
     1997 Employee Stock Purchase Plan. The Company's 1997 Employee Stock
Purchase Plan (the "Purchase Plan") was adopted by the Board of Directors in May
1997 and approved by the stockholders in             , 1997. A total of 400,000
shares of Common Stock, plus annual increases equal to the lowest of (i) 150,000
shares, (ii) 1% of the outstanding shares or (iii) a lesser amount determined by
the Board of Directors has been reserved for issuance under the Purchase Plan.
The Purchase Plan, which is intended to qualify under Section 423 of the Code,
is administered by the Board of Directors or by a committee appointed by the
Board. Employees (including officers and employee directors of the Company but
excluding 5% or greater stockholders or persons whose right to purchase Common
Stock accrues at a rate greater than $25,000 worth of Common Stock per year) are
eligible to participate if they are customarily employed for at least 20 hours
per week and for more than five months in any calendar year. The Purchase Plan
permits eligible employees to purchase Common Stock through payroll
 
                                       52
<PAGE>   54
 
deductions, which may not exceed 10% of an employee's compensation. The Purchase
Plan will be implemented by consecutive overlapping twelve (12) month offering
periods. The initial offering period under the Purchase Plan will begin on the
effective date of this Offering and subsequent offering periods will begin on
the first trading day on or after May 1 and November 1 of each year. Each
participant will be granted an option on the first day of the offering period,
and shares of Common Stock will be automatically purchased on the last date of
each purchase period within the offering period. If the fair market value of the
Common Stock on any purchase date (other than the final purchase date of the
offering period) is lower than such fair market value on the start date of that
offering period, then all participants in that offering period will be
automatically withdrawn from such offering period and re-enrolled in the
immediately following offering period. The purchase price of the Common Stock
under the Purchase Plan will be equal to 85% of the lesser of the fair market
value per share of Common Stock on the start date of the offering period or on
the purchase date. Employees may end their participation in an offering period
at any time, and participation ends automatically on termination of employment
with the Company. In the event of a proposed dissolution or liquidation of the
Company, the offering periods then in progress will be shortened by setting a
new exercise date that is before the dissolution or liquidation, and will
terminate immediately prior to the consummation of the proposed action, unless
otherwise provided by the Board. In the event of a proposed sale of all or
substantially all of the Company's assets or the merger of the Company with or
into another corporation, each outstanding option will be assumed or substituted
for by the successor corporation. In the event the successor corporation refuses
to assume or substitute for the options, the offering periods then in progress
will be shortened by setting a new exercise date that is before the sale or
merger and the offering periods then in progress will end on the new exercise
date. Each participant will be notified at least ten business days prior to the
new exercise date, and unless such participant ends his or her participation,
the option will be exercised automatically on the new exercise date. The
Purchase Plan will terminate in May 2007, unless sooner terminated by the Board
of Directors.
 
     1997 Director Option Plan. The Company's 1997 Director Option Plan (the
"Director Plan") was adopted by the Board of Directors in May 1997 and approved
by the Company's stockholders in             1997. A total of 175,000 shares of
Common Stock, plus annual increases equal to the lesser of (i) the optioned
stock underlying options granted in the immediately preceding year, or (ii) a
lesser amount determined by the Board of Directors has been reserved for
issuance under the Director Plan. The option grants under the Director Plan are
automatic and non-discretionary, and the exercise price of the options is 100%
of the fair market value of the Common Stock on the grant date. The Director
Plan provides for an initial grant of options to purchase        shares of
Common Stock to each new non-employee director of the Company (an "Outside
Director") upon the later of the effective date of the Director Plan or the date
which such individual first becomes an Outside Director. In addition, each
Outside Director will automatically be granted subsequent options to purchase
5,000 shares of Common Stock at the first meeting of the Board of Directors
following the annual meeting of stockholders in each year beginning with the
1997 Annual Meeting of Stockholders if on such date, such Outside Director has
served on the Board of Directors for at least six months. The term of each such
option is ten years. Each option granted to an Outside Director vests as to 25%
of the optioned stock on the first anniversary of the date of grant and as to
1/48th of the optioned stock each month thereafter. In the event of the sale of
all or substantially all the Company's assets or the merger of the Company with
or into another corporation, all outstanding options under the Director Plan may
either be assumed or an equivalent option may be substituted by the surviving
entity. Following such assumption or substitution, if the director is terminated
other than upon a voluntary resignation, such option will vest and become
exercisable in full. If no assumption or substitution occurs, each such option
will vest and become exercisable in full. The Director Plan will terminate in
May 2007 unless sooner terminated by the Board of Directors.
 
401(K) PLAN
 
     The Company participates in a tax-qualified employee savings and retirement
plan (the "401(k) Plan") which covers all of the Company's full-time employees
who are at least 21 years of age. Pursuant to the 401(k) Plan, employees may
elect to reduce their current compensation by up to the lower of 15%
 
                                       53
<PAGE>   55
 
or the statutorily prescribed annual limit and have the amount of such reduction
contributed to the 401(k) Plan. The 401(k) Plan permits additional discretionary
matching contributions by the Company on behalf of all participants in the
401(k) Plan in such a percentage amount as may be determined annually by the
Board of Directors. To date, the Company has made no such matching
contributions. The 401(k) Plan is intended to qualify under Section 401 of the
Code, so that contributions by employees or by the Company to the 401(k) Plan,
and income earned on plan contributions, are not taxable to employees until
withdrawn from the 401(k) Plan, and so that contributions by the Company, if
any, will be deductible by the Company when made. The trustee under the 401(k)
Plan, at the direction of each participant, invests the assets of the 401(k)
Plan in any of a number of investment options.

                                       54
<PAGE>   56
 
following, a change in control of the Company. In addition, upon a change in

1997 governing Mr. Moore's resignation as an executive officer of the Company.
Mr. Moore resigned as President of Synon Europe Limited, effective December 31,
1996. Pursuant to the agreement and in connection with Mr. Moore's resignation,
Mr. Moore was paid a total of UK L138,000, which amount included a severance
payment of UK L116,000 (equal to one year's base salary), a discretionary bonus
and accrued holiday pay. As additional severance consideration, and in exchange
for Mr. Moore's agreement not to compete with or solicit employees from the
Company, the Company agreed to extend through November 30, 1997 the
exercisability of vested options held by Mr. Moore to acquire 110,000 shares of
the Company's Common Stock.
 
     The Company and Simon Williams, the Company's former Vice President,
Development and Chief Technology Officer, are parties to an agreement dated July

Obsydian product (1% following Mr. Williams' leaving the Company). The Williams
Agreement was entered into in connection with the Company's acquisition of Dysys
Limited. Mr. Williams resigned his positions effective December 31, 1996 and
thus no longer receives a salary from the Company. However, Mr. Williams will
continue to receive a 1% Obsydian commission until June 30, 1999, and after such
time will receive a 1% commission with respect to any Obsydian-related contracts
entered into prior June 30, 1999. See "Certain Transactions -- Dysys Agreement."
 
     The Company's 1990 Plan provides for the accelerated vesting of shares of
Common Stock subject to outstanding options held by Company employees, including
the Named Executive Officers, in connection with certain changes in control of
the Company. See "-- Stock Plans -- 1990 Stock Plan."
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS
 
     The Company has adopted provisions in its Certificate of Incorporation that
eliminate to the fullest extent permissible under Delaware law the liability of
its directors to the Company for monetary damages. Such limitation of liability
does not affect the availability of equitable remedies such as injunctive relief
or rescission. The Company's Bylaws provide that the Company shall indemnify its
directors and officers, and may indemnify its other employees and agents, to the
fullest extent permitted by Delaware law, including in circumstances in which
indemnification is otherwise discretionary under Delaware law. The Company has
entered into indemnification agreements with its officers and directors
containing provisions which may require the Company, among other things, to
indemnify the officers and directors against certain liabilities that may arise
by reason of their status or service as directors or officers (other than
liabilities arising from willful misconduct of a culpable nature), and to
advance their expenses incurred as a result of any proceeding against them as to
which they could be indemnified.
 
     There is no currently pending litigation or proceeding involving a
director, officer, employee or other agent of the Company in which
indemnification would be required or permitted. The Company is not aware of any
threatened litigation or proceeding which may result in a claim for such
indemnification.

                              CERTAIN TRANSACTIONS
 
AGREEMENTS WITH OFFICERS AND DIRECTORS
 
     Synon has employment agreements with certain of its Named Executive
Officers. See "Management -- Employment, Severance and Change in Control
Arrangements."
 
     On March 27, 1991, Synon entered into an agreement with Paul K. Wilde, the
Company's Vice President, Finance and Administration, Chief Financial Officer
and Secretary, whereby Synon agreed to lend $200,000 to Mr. Wilde for the
purchase of a new principal residence pursuant to a five-year recourse
promissory note that bears interest at 8% per annum. The note, which was
executed in September 1992 and amended on January 14, 1992, was secured by a
junior security interest in the residence. Synon agreed to forgive the amount of
principal due on the note over the course of five years beginning on April 15,
1991 (Mr. Wilde's employment start date) at the rate of 1/60th of the principal
balance per month. Synon agreed to forgive the amount of interest due on the
note in the form of annual bonus payments equal to the amount of interest due.
The final remaining principal balance was forgiven on April 15, 1996.
 
     Pursuant to an offer letter from the Company dated April 14, 1993, John F.
Rockart, a director of the Company, is entitled to receive consulting fees at an
annual rate of $15,000, payable monthly, in exchange for his services as a
member of the Board of Directors. In addition, the Company granted Mr. Rockart
an option to purchase 10,000 shares of its Common Stock at an exercise price of
$2.86 per share. See "Management -- Director Compensation."
 
DYSYS AGREEMENT
 
     Pursuant to the Dysys Agreement, the Company purchased from Simon Williams
and Melinda Horton, founders and major stockholders of the Company, all of the
issued share capital of Dysys for UK L147,542, of which UK L73,771 was paid to
Mr. Williams. In addition, the Company repaid UK L95,871 in loans made by Mr.
Williams and Ms. Horton to Dysys. Of this amount, UK L58,951 was repaid to Mr.
Williams. In connection with this transaction, the Company acquired from Dysys
certain intellectual property which was included in the Company's Obsydian
product. The Company also entered into employment agreements with each of Mr.
Williams and Ms. Horton, pursuant to which the Company currently incurs a
liability to pay Mr. Williams and Ms. Horton a 1.0% and 0.5% commission,
respectively, on Obsydian license and maintenance revenue for all transactions
entered into by the Company during the five year period from July 1, 1994 until
June 30, 1999. The commissions due to Mr. Williams and Ms. Horton originally
were 2.0% and 1.0%, respectively. However, their employment agreements each
provided that, upon voluntary termination of their employment, the commissions
would be reduced by half. Mr. Williams and Ms. Horton resigned their positions
with the Company in December 1996. Commissions earned by Mr. Williams under his
employment agreement during 1994, 1995 and 1996 were $66,000, $205,000 and
$301,000, respectively. Under the Dysys Agreement, Mr. Williams and Ms. Horton
also retain certain rights with respect to the intellectual property, including
the non-exclusive right to use and exploit it in the event of certain defaults
by the Company, including failure to pay commissions required in connection with
the Dysys Agreement.
 
PREFERRED STOCK SALES
 
     In September 1991, General Atlantic Partners II, L.P. ("GAP II"), a major
stockholder of the Company, purchased 2,776,120 (pre-conversion) shares of the
Company's Series D Preferred Stock at a purchase price of $3.35 per share as
part of a financing with other investors. In connection with such financing, GAP
II also exchanged previously held shares of the Company's capital stock for an
aggregate of 827,098 (pre-conversion) additional shares of Preferred Stock and
received certain registration rights with respect to the Company's Common Stock
owned by it. The Company's Certificate of Incorporation provides that, upon
conversion, holders of Series D Preferred Stock are entitled to receive
additional conversion consideration in the amount of $3.35 per share, payable
either in cash or in equity securities of
 
                                       56
<PAGE>   58
 
the Company. Currently, the Company has 3,618,269 shares of Series D Preferred
Stock issued and outstanding, of which 3,260,060 shares are held by GAP II.
Thus, upon the closing of this Offering and the conversion of all outstanding
shares of Preferred Stock, the holders of Series D Preferred Stock will receive
shares of Common Stock worth approximately $12,121,201, of which amount
approximately $10,921,201 will be issuable to GAP II. Directors Grabe and
Hodgson are managing members of General Atlantic Partners, LLC, the general
partner of GAP II. See "Management -- Executive Officers, Directors and Key
Employees" and "Description of Capital Stock -- Registration Rights."
 
     On August 28, 1992, IBM purchased 1,666,667 (pre-conversion) shares of the
Company's Series E Preferred Stock at a price of $3.00 per share pursuant to a
stock purchase agreement (the "Stock Purchase Agreement"). As originally
executed, the Stock Purchase Agreement, among other things, granted IBM a right
of first refusal with respect to change in control transactions, a right to
require the Company to repurchase its shares of Series E Preferred Stock in
certain circumstances and the right to nominate an individual to the Company's
Board of Directors (collectively, the "IBM Rights"). IBM has never exercised its
right to nominate a director. Mr. William M. Stuek, General Manager of
Operations for IBM North America, serves on the Company's Board of Directors,
but does so in his personal capacity at the request of GAP II, and is not
serving at the request of IBM and does not represent IBM in this capacity. On
May 28, 1997, the Company and IBM entered into an amendment to the Stock
Purchase Agreement pursuant to which IBM agreed to the automatic termination of
the IBM Rights effective and contingent upon the closing of this Offering.
 
STOCKHOLDERS AGREEMENT
 
     The Company, IBM, GAP II, Simon Williams, director William O. Grabe, and
several other significant stockholders (collectively, the "Stockholder Parties")
are parties to a Third Amended and Restated Stockholders Agreement (the
"Stockholders Agreement") dated June   , 1997, pursuant to which the Stockholder
Parties were granted a right of first refusal to purchase any future voting
securities offered by the Company (excluding shares issued in a firm commitment
underwritten public offering). Certain Stockholder Parties were also granted the
right to elect one or more persons to the Company's Board of Directors. These
stockholder rights will automatically terminate upon the closing of this
Offering. The Stockholders Agreement also entitles the Stockholder Parties to
certain registration rights with respect to the Company's Common Stock owned by
them. See "Description of Capital Stock -- Registration Rights."
 
AGREEMENTS WITH IBM
 
     The Company and IBM's AS/400 division are parties to an agreement dated
December 20, 1996, pursuant to which the Company agreed to develop and IBM's
AS/400 division agreed to partially fund a Synon/2E and Obsydian
internet/intranet enablement using a Java generator on the IBM AS/400. The
agreement provides for IBM's AS/400 division to pay the Company up to $200,000,
subject to the Company's attainment of certain development milestones. As of
March 31, 1997, the Company had accrued $140,000 under this agreement.
 
     On September 27, 1990, the Company and IBM's AS/400 division entered into a
Development Incentive Agreement (the "Development Agreement") pursuant to which
IBM's AS/400 division loaned the Company $1.5 million to assist in the
development of an application generator tool for the IBM AS/400. The loan
initially was interest-free. However, in connection with IBM's purchase of
shares of the Company's Series E Preferred Stock in August 1992, the Company and
IBM agreed that, beginning January 1, 1994, the loan would accrue interest at 8%
per annum. The Company and IBM also agreed to extend the loan repayment schedule
and to provide for repayment of the loan in twelve increasing quarterly
installments beginning in March 1994. In December 1996, the Company made its
final loan payment to IBM under the Development Agreement.
 
     The Company and CGI, a subsidiary of IBM, are parties to a distributorship
agreement dated January 8, 1996 pursuant to which CGI is designated as a
non-exclusive distributor in Germany for the
 
                                       57
<PAGE>   59
 
Company's products. Under the agreement, CGI licenses products from the Company,
grants sublicenses to such products to end-user customers and provides
maintenance and first-level technical support to such end-users. CGI has the
right to appoint sub-distributors, subject to the prior written approval of the
Company. The distributorship agreement also provides that CGI shall pay to the
Company a commission on all license and maintenance agreements. The agreement is
due to expire on January 8, 2001, however either party may terminate with 90
days' written notice upon the third, fourth or fifth anniversary of the date of
the agreement, and the Company may unilaterally terminate earlier for CGI's
breach, failure to meet the sales quota for two consecutive quarters,
insolvency, bankruptcy, change of control or an unauthorized assignment.
 
     The Company and IBM are parties to a Software Vendor Marketing Programs
Agreement dated March 7, 1997. Under this agreement, IBM has agreed to market
Obsydian as an application development solution. In exchange, the Company has
agreed to pay IBM a fee based on a percentage of the total license revenue
received by the Company on certain transactions under user agreements entered
into as a result of IBM's marketing efforts.
 
     The Company and IBM's AS/400 division are parties to a sponsored
development agreement dated April 1, 1997 (the "JumpStart Agreement"), pursuant
to which IBM's AS/400 division has agreed to assist the Company in the
development of four business object Class Libraries which can be assembled and
deployed through Obsydian. IBM's AS/400 division has agreed to provide the
necessary equipment, facilities and funding to support the joint project. In
exchange, the Company has agreed to pay IBM a royalty based on a percentage of
the Company's published sales price for each copy of Class Library licensed,
supported or sold for a period of two years after the general availability of
each Class Library. In connection with the JumpStart Agreement, the Company
contracted with CGI Systems Inc., a subsidiary of IBM, to provide two
application consultants to work on the joint development project with IBM in its
JumpStart Lab in Rochester, Minnesota. The estimated total value of this
engagement is $300,000.

                          DESCRIPTION OF CAPITAL STOCK
GENERAL
 
     Upon the closing of this Offering, the Company will be authorized to issue
50,000,000 shares of Common Stock, $0.001 par value, and 5,000,000 shares of
undesignated Preferred Stock, $0.001 par value. Based upon shares outstanding as
of March 31, 1997 and assuming no exercise of the Underwriters' over-allotment
option, the Company estimates that immediately after the closing of this
Offering there will be an aggregate of        shares of Common Stock
outstanding,        shares of Common Stock will be issuable upon exercise of
outstanding options and no shares of Preferred Stock will be issued and
outstanding.
 
     The following description of the Company's capital stock does not purport
to be complete and is subject to and qualified in its entirety by the Company's
Amended and Restated Certificate of Incorporation and Bylaws, which are included
as exhibits to the Registration Statement of which this Prospectus forms a part,
and by the provisions of applicable Delaware law.
 
     The Amended and Restated Certificate of Incorporation and Bylaws contain
certain provisions that are intended to enhance the likelihood of continuity and
stability in the composition of the Board of Directors and which may have the
effect of delaying, deferring, or preventing a future takeover or change in
control of the Company unless such takeover or change in control is approved by
the Board of Directors.
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote per share on all matters
to be voted upon by the stockholders. Holders of Common Stock do not have
cumulative voting rights, and, therefore, holders of a majority of the shares
voting for the election of directors can elect all of the directors. In such
event, the holders of the remaining shares will not be able to elect any
directors.
 
     Holders of the Common Stock are entitled to receive such dividends as may
be declared from time to time by the Board of Directors out of funds legally
available therefor, subject to the terms of any existing or future agreements
between the Company and its debtholders. The Company has never declared or paid
cash dividends on its capital stock, expects to retain future earnings, if any,
for use in the operation and expansion of its business, and does not anticipate
paying any cash dividends in the foreseeable future. In addition, the Company's
bank line of credit agreement contains a restrictive covenant that limits the
Company's ability to pay cash dividends or make certain stock repurchases
without the prior written consent of the lender. See "Dividend Policy." In the
event of the liquidation, dissolution or winding up of the Company, the holders
of Common Stock are entitled to share ratably in all assets legally available
for distribution after payment of all debts and other liabilities and subject to
the prior rights of any holders of Preferred Stock then outstanding.
 
PREFERRED STOCK
 
     Effective upon the closing of this Offering, the Company will be authorized
to issue 5,000,000 shares of undesignated Preferred Stock. The Board of
Directors has the authority to issue the Preferred Stock in one or more series
and to fix the price, rights, preferences, privileges and restrictions thereof,
including dividend rights, dividend rates, conversion rights, voting rights,
terms of redemption, redemption prices, liquidation preferences and the number
of shares constituting a series or the designation of such series, without any
further vote or action by the Company's stockholders. The issuance of Preferred
Stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of delaying,
deferring or preventing a change in control of the Company without further
action by the stockholders and may adversely affect the market price of, and the
voting and other rights of, the holders of Common Stock. The issuance of
Preferred Stock with voting and conversion rights may adversely affect the
voting power of the holders of Common Stock, including the loss of voting
control to others. The Company has no current plans to issue any shares of
Preferred Stock.

ANTITAKEOVER EFFECTS OF PROVISIONS OF CERTIFICATE OF INCORPORATION AND BYLAWS
 
     The Company's Amended and Restated Certificate of Incorporation provides
that all stockholder actions must be effected at a duly called annual or special
meeting and may not be effected by written consent. The Company's Bylaws provide
that, except as otherwise required by law, special meetings of the stockholders
can only be called pursuant to a resolution adopted by a majority of the Board
of Directors, by the Chairman of the Board of Directors, by the Chief Executive
Officer of the Company or by stockholders holding shares in the aggregate
entitled to cast not less than 20% of the votes at such meeting. In addition,
the Company's Bylaws establish an advance notice procedure for stockholder
proposals to be brought before an annual meeting of stockholders, including
proposed nominations of persons for election to the Board. Stockholders at an
annual meeting may only consider proposals or nominations specified in the
notice of meeting or brought before the meeting by or at the direction of the
Board of Directors or by a stockholder who was a stockholder of record on the
record date for the meeting, who is entitled to vote at the meeting and who has
delivered timely written notice in proper form to the Company's Secretary of the
stockholder's intention to bring such business before the meeting.
 
     The foregoing provisions of the Company's Amended and Restated Certificate
of Incorporation and Bylaws are intended to enhance the likelihood of continuity
and stability in the composition of the Board of Directors and in the policies
formulated by the Board of Directors and to discourage certain types of
transactions which may involve an actual or threatened change of control of the
Company. Such provisions are designed to reduce the vulnerability of the Company
to an unsolicited acquisition proposal and, accordingly, could discourage
potential acquisition proposals and could delay or prevent a change in control
of the Company. Such provisions are also intended to discourage certain tactics
that may be used in proxy fights but could, however, have the effect of
discouraging others from making offers for the Company's shares and,
consequently, may also inhibit fluctuations in the market price of the Company's
shares that could result from actual or rumored takeover attempts. These
provisions may also have the effect of preventing changes in the management of
the Company. See "Risk Factors -- Effect of Certain Charter Provisions;
Antitakeover Effects of Certificate of Incorporation, Bylaws and Delaware Law."
 
EFFECT OF DELAWARE ANTITAKEOVER STATUTE
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law (the "Antitakeover Law"), which regulates corporate acquisitions. The
Antitakeover Law prevents certain Delaware corporations, including those whose
securities are listed for trading on the Nasdaq National Market, from engaging,
under certain circumstances in a "business combination" with any "interested
stockholder" for three years following the date that such stockholder became an
interested stockholder. For purposes of the Antitakeover Law, a "business
combination" includes, among other things, a merger or consolidation involving
the Company and the interested shareholder and the sale of more than ten percent
(10%) of the Company's assets. In general, the Antitakeover Law defines an
"interested stockholder" as any entity or person beneficially owning 15% or more
the outstanding voting stock of the Company and any entity or person affiliated
with or controlling or controlled by such entity or person. A Delaware
corporation may "opt out" of the Antitakeover Law with an express provision in
its original certificate of incorporation or an express provision in its
certificate of incorporation or bylaws resulting from amendments approved by the
holders of at least a majority of the Company's outstanding voting shares. The
Company has not "opted out" of the provisions of the Antitakeover Law. See "Risk
Factors -- Effect of Certain Charter Provisions; Antitakeover Effects of
Certificate of Incorporation, Bylaws and Delaware Law."
 
REGISTRATION RIGHTS
 
     After the closing of this Offering and upon expiration of lock-up
agreements with the Underwriters, the holders of           shares of Common
Stock will be entitled to certain rights with respect to the registration of
such shares under the Securities Act. Under the terms of the Stockholders
Agreement, if the Company proposes to register any of its securities under the
Securities Act, either for its own account or for the account of other
securities holders exercising registration rights, such holders are entitled to
notice of such registration and are entitled to include certain of their shares
of Common Stock therein.
 
                                       63
<PAGE>   65
 
Holders of registration rights may also require the Company to file a
registration statement under the Securities Act at the Company's expense with
respect to their shares of Common Stock, and the Company is required to use its
best efforts to effect such registration. Further, holders may require the
Company to file registration statements on Form S-3 at the Company's expense
when such form becomes available for use to the Company. All such registration
rights are subject to certain conditions and limitations, including the right of
the underwriters of an offering to limit the number of shares to be included in
such registration.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to this Offering, there has been no market for the Common Stock and
there is no assurance that a significant public market for the Common Stock will
develop or be sustained after this Offering. Sales of substantial amounts of
Common Stock in the public market could adversely affect the market price of the
Common Stock and could impair the Company's future ability to raise capital
through the sale of its equity securities.
 
     Upon the closing of this Offering, the Company will have outstanding
          shares of Common Stock based upon shares outstanding as of March 31,
1997. In addition to the           shares of Common Stock offered hereby
(          if the Underwriters' over-allotment option is exercised in full), as
of the effective date of the Registration Statement (the "Effective Date"),
there will be           shares of Common Stock outstanding (excluding 1,366,730
shares issuable upon the exercise of outstanding options), all of which are
"restricted" shares (the "Restricted Shares") under the Securities Act of 1933,
as amended (the "Securities Act"). Such Restricted Shares may be sold only if
registered under the Securities Act or sold in accordance with an available
exemption from such registration. Approximately           of the Restricted
Shares will be freely tradeable without restriction immediately following the
Effective Date pursuant to Rule 144(k) of the Securities Act by persons who are
not "affiliates" of the Company as the term is defined in Rule 144.
 
     Effective April 29, 1997, under Rule 144, a person (or persons whose shares
are aggregated in accordance with the Rule) who has beneficially owned his or
her shares for at least one year, including persons who are affiliates of the
Company, would be entitled to sell, within any three month period a number of
shares of Common Stock that does not exceed the greater of (i) one percent of
the then outstanding number of shares of Common Stock (up to           shares of
Common Stock immediately after the consummation of the Offering) or (ii) the
average weekly trading volume of the shares during the four calendar weeks
preceding each such sale. In addition, sales under Rule 144 are also subject to
certain manner of sale provisions and notice requirements and to the
availability of current public information about the Company. After shares are
held for two years, a person who is not an affiliate of the Company is entitled
to sell such shares under Rule 144 without regard to such volume limitations, or
manner of sale, notice or public information requirements under Rule 144. Sales
of shares by affiliates will continue to be subject to such volume limitations,
and manner of sale, notice and public information requirements. Under Rule 701,
shares issued under certain compensatory stock-based plans, such as the 1990
Plan and the Executive Scheme, may be resold under Rule 144 by nonaffiliates
subject only to the manner of sale requirements, and by affiliates without
regard to the two-year holding period requirements, commencing 90 days after the
date of this Offering.
 
     The Company, its officers and directors and certain holders of Common Stock
and options to purchase Common Stock have each agreed with the Underwriters not
to offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, or otherwise transfer or dispose of, directly or
indirectly, or announce the offering of, or file or cause to be filed, any
registration statements (other than, in the Company's case, a registration
statement on Form S-8) under the Securities Act, with respect to any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock, except in certain cases as to shares acquired after the
Offering, or enter into any swap or other agreement that transfers, in whole or
in part, the economic consequences of ownership of the Common Stock for a period
of 180 days after the date of the Underwriting Agreement without the prior
written consent of Salomon Brothers Inc. Certain other holders of Common Stock
and options to purchase Common Stock have agreed pursuant to existing agreements
with the Company not to sell or otherwise transfer or dispose of any Common
Stock for a period of 180 days after the effective date of this Offering.
 
     Beginning 180 days after the Effective Date, approximately
additional Restricted Shares of Common Stock subject to the lock-up agreements
will become eligible for sale in the public market (unless the Representatives
elect, in their sole discretion, the earlier release of such shares from the
lock-up agreement) pursuant to Rule 144.
 
                                       65
<PAGE>   67
 
     After the Offering pursuant to this Prospectus, the holders of
shares of Common Stock, or their transferees, will be entitled to certain rights
with respect to the registration of such shares under the Securities Act. See
"Description of Capital Stock -- Registration Rights." Registration of such
shares under the Securities Act would result in such shares becoming freely
tradeable without restriction under the Securities Act (except for shares
purchased by affiliates under Rule 144) immediately upon the effectiveness of
such registration.
 
     The Company intends to file registration statements on Form S-8 shortly
after this Offering to cover shares of Common Stock which have been reserved for
issuance under the 1990 Plan, Executive Scheme, 1997 Incentive Stock Plan,
Purchase Plan and 1997 Director Option Plan. Shares so registered will be
eligible for sale by non-affiliates in the public market without limitation and
by affiliates subject to the provisions of Rule 144, except for the holding
period limitation. Shares of Common Stock issued upon exercise of options after
the effective date of the Form S-8 will be available for sale in the public
market, subject to Rule 144 limitations and lock-up agreements. Beginning 180
days after the Effective Date,           shares issuable upon the exercise of
vested options will be eligible for sale.
 
     Rule 144A under the Securities Act would permit the immediate sale of
Restricted Shares to qualified institutional buyers, subject to compliance with
conditions of the Rule.

     Upon the terms and subject to the conditions set forth in the Underwriting
Agreement, the Company and the Selling Stockholders have agreed to sell to each

Inc and Volpe, Brown, Whelan & Company, LLC are acting as representatives (the

</TABLE>
 
     In the Underwriting Agreement, the several Underwriters have agreed,
subject to the terms and conditions set forth therein, to purchase all the
Shares offered hereby (other than those subject to the over-allotment option
described below) if any such Shares are purchased. In the event of a default by
an Underwriter, the Underwriting Agreement provides that, in certain
circumstances, the purchase commitments of the non-defaulting Underwriters may
be increased or the Underwriting Agreement may be terminated.
 
     The Representatives have advised the Company and the Selling Stockholders
that the several Underwriters propose initially to offer the Shares to the
public at the price to public set forth on the cover page of this Prospectus and
to certain dealers at such price less a concession not in excess of $
per share. The Underwriters may allow and such dealers may reallow a concession
not in excess of $          per share to other dealers. After the initial public
Offering, the price to public and such concessions may be changed.
 
     Certain Selling Stockholders have granted the Underwriters an option,
exercisable within 30 days of the date of this Prospectus, to purchase up to
          additional shares of Common Stock at the same price per share as the
initial           shares of Common Stock to be purchased by the Underwriters.
The Underwriters may exercise such option only to cover over-allotments, if any,
incurred in connection with the Offering. To the extent the Underwriters
exercise such option, each Underwriter will have a firm commitment, subject to
certain conditions, to purchase the same proportion of such additional shares of
Common Stock as the number of shares of Common Stock to be purchased and offered
by such Underwriter in the table above bears to the total number of shares of
Common Stock initially offered by the Underwriters hereby.
 
     The Underwriting Agreement provides that the Company and the Selling
Stockholders, jointly and severally, will indemnify the several Underwriters
against certain liabilities, including liabilities under the Securities Act, or
contribute to payments the Underwriters may be required to make in respect
thereof.
 
     In connection with this Offering, certain Underwriters and selling group
members and their respective affiliates may engage in transactions that
stabilize, maintain or otherwise affect the market price of the Common Stock.
Such transactions may include stabilization transactions effected in accordance
with Rule 104 of Regulation M, pursuant to which such persons may bid for or
purchase Common Stock for the purpose of stabilizing its market price. The
Underwriters also may create a short position for the account of the
Underwriters by selling more Common Stock in connection with the Offering than
they are committed to purchase from the Company and the Selling Stockholders,
and in such case may purchase Common Stock in the open market following
completion of the Offering to cover all or a portion of such
 
                                       67
<PAGE>   69
 
short position. The Underwriters may also cover all or a portion of such short
position, up to           shares of Common Stock, by exercising the
Underwriters' over-allotment option referred to above. In addition, Salomon
Brothers Inc, on behalf of the Underwriters, may impose "penalty bids" under
contractual arrangements with the Underwriters whereby it may reclaim from an
Underwriter (or dealer participating in the Offering) for the account of the
other Underwriters, the selling concession with respect to Common Stock that is
distributed in the Offering but subsequently purchased for the account of the
Underwriters in the open market. Any of the transactions described in this
paragraph may result in the maintenance of the price of the Common Stock at a
level above that which might otherwise prevail in the open market. None of the
transactions described in this paragraph is required, and, if they are
undertaken, they may be discontinued at any time.
 
     The Company, its officers and directors and certain holders of Common Stock
and options to purchase Common Stock have each agreed with the Underwriters not
to offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, or otherwise transfer or dispose of, directly or
indirectly, or announce the offering of, or file or, cause to be filed, any
registration statement (other than, in the Company's case, a registration
statement on Form S-8) under the Securities Act, with respect to any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock, except in certain cases as to shares acquired after the
Offering, or enter into any swap or other agreement that transfers, in whole or
in part, the economic consequences of ownership of the Common Stock for a period
of 180 days after date of the Underwriting Agreement without the prior written
consent of Salomon Brothers Inc. Certain other holders of Common Stock and
options to purchase Common Stock have agreed pursuant to existing agreements
with the Company not to sell or otherwise transfer or dispose of any Common
Stock for a period of 180 days after the effective date of this Offering.
 
     The Underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.
 
     Prior to this Offering, there has been no public market for the Common
Stock. Accordingly, the initial public offering price for the Common Stock was
determined by negotiation among the Company, the Selling Stockholders and the
Representatives. Among the factors considered in determining the initial public
offering price were the Company's record of operations, its current financial
condition, its future prospects, the market for its services, the experience of
management, the economic conditions of the Company's industry in general, the
general condition of the equity securities market and the demand for similar
securities of companies considered comparable to the Company and other relevant
factors. There can be no assurance, however, that the prices at which the Common
Stock will sell in the public market after this Offering will not be lower than
the price at which the Shares are sold by the Underwriters.
 
                                 LEGAL MATTERS
 
     The validity of the Common Stock offered hereby will be passed upon for the
Company by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo
Alto, California. Cleary, Gottlieb, Steen & Hamilton, New York, New York, is
acting as counsel for the Underwriters in connection with certain legal matters
relating to the shares of Common Stock offered hereby.

         After the transactions discussed in Note 17 to Synon
         Corporation's consolidated financial statements are effected,
         we expect to be in a position to render the following audit
         report.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders of
Synon Corporation:
 
     We have audited the accompanying consolidated balance sheets of Synon
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1995
and 1996, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free 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 financial position of Synon
Corporation and subsidiaries as of December 31, 1995 and 1996, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1996, in conformity with generally accepted accounting
principles.

its Australian subsidiary, Synon Pty Ltd.
 
CONCENTRATION OF BUSINESS RISKS
 
     The market for the Company's products and services is characterized by
intense competition, rapid technological developments, frequent new product
introductions and evolving industry standards. Accordingly, the Company is
required to continually improve the performance, features and reliability of its
products and develop and maintain strategic relationships with larger companies.
 
     Historically, most of the Company's license revenues have been attributable
to the Synon 2E product family. Beginning in 1995, a significant portion of the
Company's license revenue has been attributable to the Obsydian product family.
The Company expects the Obsydian product family to account for an increasingly
significant portion of the Company's revenues for the foreseeable future.
 
     The Company operates in foreign countries located in Asia, Australia,
Europe, North America and South America and is impacted by the economic and
political stability of nations in these regions.
 
     In addition, as discussed in Note 12, the Company has excess space under
long-term leases. While the space is currently subleased, the Company's ability
to continue to sublease the space under economically satisfactory terms is
subject to the impact of changing market conditions.
 
CONCENTRATION OF CREDIT RISK
 
     Financial instruments that may potentially subject the Company to
concentrations of credit risk consist principally of cash and cash equivalents
and accounts receivable. Concentration of credit risk related to accounts
receivable is limited due to the varied customers comprising the Company's
customer base and their dispersion across geographies. All cash and cash
equivalents are with financial institutions with strong credit ratings, which
minimizes the risk of loss due to nonpayment. The Company has not experienced
any losses due to credit impairment related to its financial instruments.
 
SIGNIFICANT ACCOUNTING POLICIES
 
     Unaudited Pro Forma Information -- The accompanying interim balance sheet
at March 31 1997, and the statements of operations and cash flows for the three
months ended March 31, 1996 and 1997, together with the related notes, are
unaudited but include all adjustments, consisting of only normal recurring
adjustments, which the Company considers necessary to present fairly, in all
material respects, the financial condition of the Company at March 31, 1997, and
the Company's results of operations and cash flows for the three months ended
March 31, 1996 and 1997. Results for the three months ended March 31, 1997 are
not necessarily indicative of results for the entire fiscal year.

                       SYNON CORPORATION AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(INFORMATION AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS
UNAUDITED.)
 
     In conjunction with its proposed initial public offering (Note 17), all of
the Company's outstanding convertible preferred stock will be converted into
shares of common stock. The pro forma effect of these conversions, which is
unaudited, has been reflected in the accompanying pro forma consolidated balance
sheet assuming the conversion had occurred on March 31, 1997.
 
     Principles of Consolidation -- The consolidated financial statements
include the accounts of Synon Corporation and all of its subsidiaries and joint
ventures.
 
     Revenue Recognition -- The Company generates revenues from licensing the
rights to use its software products directly to end users and indirectly through
value-added resellers (VARs). The Company also generates revenues from sales of
post-contract support, consulting and training services performed for customers
who license the Company's products.
 
     The Company recognizes revenues and records estimated warranty reserves
from software license agreements with end users and VARs upon shipment of the
software if there are no significant post-delivery obligations and if collection
is probable. If a software license agreement provides for acceptance criteria
that extend beyond the published specifications of the applicable product, then
revenues are recognized upon the earlier of customer acceptance or the
expiration of the acceptance period.
 
     Customers who purchase post-contract support services under maintenance
agreements have the right to receive unspecified product updates, upgrades and
enhancements. Customers that do not purchase post-contract support must purchase
product updates, upgrades and enhancements under separate agreements that are
subject to the criteria of the Company's revenue recognition policy.
 
     Revenues from post-contract support services are recognized ratably over
the term of the support period. If post-contract support services are included
free or at a discount in a license agreement, such amounts are allocated out of
the license fee at their fair market value based on the value established by
independent sale of such post-contract support services to customers. Consulting
revenues are primarily related to implementation services performed on a time
and materials basis and fixed-price contracts under separate service
arrangements related to the installation of the Company's software products and
software development using the Company's software products. Revenues from
consulting and training services are recognized as services are performed except
for fixed-price contracts. Revenues from fixed-price contracts are recognized on
the percentage-of-completion method, measured by the cost incurred to date, to
estimated total costs for each contract. If a transaction includes both license
and service elements, license fee revenue is recognized upon shipment of the
software, provided services do not include significant customization or
modification of the base product and the payment terms for licenses are not
subject to acceptance criteria. In cases where license fee payments are
contingent upon the acceptance of services, revenues from both the license and
the service elements are deferred until the acceptance criteria are met. In
situations where there are undelivered elements that are critical to
functionality of the software product, the entire license fee is deferred.
 
     Deferred revenues include software license fees and services that have been
invoiced to the customer for which the revenue earnings process has not been
completed.
 
     Use of Estimates -- The preparation of the consolidated financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the dates of the consolidated financial statements and the reported amounts of
revenues and expenses during the reporting periods. Actual results could differ
from those estimates.
 
     Significant estimates made by management include revenue recognition under
fixed-price contracts, determination of technological feasibility of software
under development and related research and

development cost capitalization, as well as product life amortization periods
for capitalized software costs.
 
     Supplemental Cash Flow Information -- During the years ended December 31,
1994, 1995 and 1996, and during the three months ended March 31, 1996 and 1997,
the Company paid interest of approximately $412,000, $258,000, $125,000, $38,000
and $18,000, respectively, and income taxes of approximately $533,000, $177,000,
$719,000, $188,000 and $186,000, respectively.
 
     During the years ended December 31, 1994, 1995 and 1996, and during the
three months ended March 31, 1996 and 1997, capital lease obligations of
approximately $676,000, $542,000, $333,000, $47,000 and $0, respectively, were
incurred relating to the acquisition of property and equipment.
 
     Cash -- Cash and cash equivalents are stated at cost, which approximates
market, and consist of short-term, highly liquid investments with original
maturities of less than three months.
 
     Property and Equipment -- Property and equipment are stated at cost and are
depreciated using the straight-line method over estimated useful lives, or
related lease terms, if shorter, as follows:

            Automobiles...........................................   4 to 5 years
</TABLE>
 
     Capitalized Software Development Costs -- The Company capitalizes software
development costs in accordance with Statement of Financial Accounting Standards
(SFAS) No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased
or Otherwise Marketed." The costs of software development are capitalized from
the date at which the technological feasibility of a product is established.
Capitalization of development costs ceases and amortization begins when a
product is available for general release to customers. Amortization is computed
separately for each product using the straight-line method over an estimated
useful life of up to five years (see Note 4).
 
     Goodwill -- Goodwill relates to the acquisition of Synon Consulting, Inc.
in 1990 and is being amortized on a straight-line basis over its estimated
useful life of 10 years. Periodically, goodwill is evaluated for indications of
impairment in its value. If impairment exists, a write-down to the net
realizable value is recorded. No such write-down occurred during the years ended
December 31, 1994, 1995 or 1996, or in the three months ended March 31, 1997.
Accumulated amortization at December 31, 1995 and 1996 and at March 31, 1997 was
approximately $9,849,000, $9,974,000 and $10,005,000, respectively.
 
     Stock Split -- In June 1997, the Company will effect a 1-for-2 reverse
stock split of its common stock (Note 17). All common stock and option data in
the accompanying consolidated financial statements for all periods presented
have been retroactively adjusted to reflect the stock split.
 
     Cost of License Revenue -- Cost of license revenue includes royalties on
third-party products, materials costs, and amortization of capitalized software
development costs.
 
     Cost of Maintenance Revenue -- Cost of maintenance revenue consists
primarily of compensation and other costs for customer support personnel,
related facilities and equipment costs, third party royalties related to
maintenance revenue, and materials costs of product updates and new releases
provided to customers.

(INFORMATION AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS
UNAUDITED.)
 
     Cost of Services Revenue -- Cost of services revenue consists primarily of
compensation and other costs for personnel providing education, consulting and
application development services, related facilities and equipment costs and
travel costs related to services engagements.
 
     Income Taxes -- The Company provides for income taxes under Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes." Under
SFAS 109, deferred income taxes are recorded to reflect the tax consequences on
future years of differences between the tax basis of assets and liabilities and
their financial reporting amounts at each period-end. Income tax benefits have
been recorded for net operating loss carryforwards, tax credit carryforwards and
net deferred tax assets except as disclosed in Note 9. A valuation allowance is
placed on the deferred tax assets to reduce them to their net realizable value.
 
     Foreign Currency Translation -- The financial statements of subsidiaries
outside the United States are generally measured using the local currency as the
functional currency. Assets and liabilities of these subsidiaries are translated
at the rates of exchange at the balance sheet date. The resultant translation
adjustments are included in equity as a cumulative foreign currency translation
adjustment, a separate component of stockholders' equity. Income and expense
items are translated at average monthly rates of exchange. Gains and losses from
foreign currency transactions of these subsidiaries are included in net
earnings. Foreign exchange transaction gains and losses of $216,000, $227,000,
$(167,000), $(18,000) and $(225,000) are included in the consolidated statements
of operations for the years ended December 31, 1994, 1995 and 1996 and for the
three months ended March 31, 1996 and March 31, 1997, respectively.
 
     Net Income (Loss) per Common and Common Equivalent Share -- Net income
(loss) per common and common equivalent share is computed using the weighted
average number of common and common equivalent shares outstanding (using the
treasury stock method). Common equivalent shares from preferred stock and stock
options are excluded from the computation if their effect is antidilutive.
Pursuant to the Securities and Exchange Commission (SEC) Staff Accounting
Bulletins, stock options and warrants issued during the 12-month period prior to
the proposed initial public offering at prices below the assumed public offering
price have been included in the calculation as if they were outstanding for all
periods presented (using the treasury stock method).
 
     Adoption of Accounting Pronouncements -- For the year ended December 31,
1997, the Company will report its Earnings per Share (EPS) based upon the
recently issued Statement of Financial Accounting Standards No. 128 (SFAS No.
128), "Earnings per Share". The pro forma effect of this accounting change on
the quarter ended March 31, 1997 is:

     The Company adopted SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for the Long-Lived Assets to be Disposed of" beginning
January 1, 1996. The Company also adopted SFAS No. 123, "Accounting for
Stock-Based Compensation," beginning January 1, 1996. The adoption of these
pronouncements did not have a material impact on the consolidated financial
statements of the Company taken as a whole.
 
     Reclassifications -- Certain reclassifications have been made to prior
years' consolidated financial statements in order to conform to the current year
presentation.

2. PREFERENCES AND RESTRICTIONS RELATED TO STOCKHOLDERS' EQUITY:
 
     Preferred stockholders are entitled to dividends only when and if declared
by the Board of Directors.
 
     Preferred stock is subject to certain preferences upon liquidation of the
Company, or upon merger or acquisition of the Company if not exempted by a
two-thirds vote of the Board of Directors.
 
     Each preferred and common share is entitled to one vote, except with
respect to certain corporate events.
 
     Each share of Series A and Series E preferred stock is convertible into
common stock on a share-for-share basis. Each share of Series D preferred stock
is convertible into one share of common stock plus $3.35 in cash (or at the
option of the Company, equity securities of the Company with an agreed-upon or
appraised market value of $3.35 per share). It is management's intention to
satisfy the conversion premium by issuing common stock. The pro forma
consolidated balance sheet as of March 31, 1997 reflects accretion of
$12,121,000 related to the conversion of Series D preferred stock, as well as
issuance of           conversion premium shares at an assumed initial public
offering price of        per share. The holders of Series D preferred stock may
convert their shares into shares of common stock upon the sale, merger or
liquidation of the Company or upon the consummation of an initial public
offering as described below. Conversion of Series A, D and E preferred stock is
automatic in the event of a public sale of common stock at not less than $10.00
per share and not less than $10 million in gross proceeds.
 
     Certain of the Company's stockholders have the right of first refusal to
purchase any new stock issued by the Company (with certain exceptions, such as
stock issued under the Company's stock option plans). This right will terminate
on the closing of the proposed Offering. (Note 16)
 
     In August 1992, IBM purchased 1,666,667 shares of Series E Preferred stock
at $3.00 per share. Under the stock purchase agreement, IBM has a right of first
refusal with respect to change in control transactions. In addition, under
certain circumstances, including a change in the Company's business, IBM may put
its 1,666,667 shares to the Company at the greater of a price of $3.00 per share
or the then-fair-market value of the shares. Notwithstanding the above, IBM may
require redemption of one-third of its shares on each of August 31, 1997, 1998
and 1999 at the then-fair-market value of the shares. On May   , 1997, the
Company and IBM entered into an amendment pursuant to which IBM agreed to the
automatic termination of these rights effective and contingent upon the closing
of the Offering.
 
     The Company and certain of the Company's stockholders also have the right
of first refusal to purchase any stock offered for sale by stockholders to any
person who, upon purchase of the shares, would own more than 10 percent of the
voting power of the Company. This right is expected to terminate upon the
closing of the Offering.
 
     Certain of the Company's common stockholders have demand registration
rights and piggyback registration rights.

6. LINE OF CREDIT:
 
     In 1996, the Company renewed a line of credit agreement (the 1996
Agreement) originally signed in 1994 (the 1994 Agreement) with a bank that
permits the Company to borrow up to $4,000,000 but not to exceed 70 percent of
eligible accounts receivable. Balances outstanding under the line accrue
interest at a rate of 1.25 percent above the bank's prime rate (8.25 percent at
December 31, 1996). The line of credit is secured by substantially all of the
Company's assets, and expires July 14, 1997. The Company is subject to certain

from $65,000 due on March 31, 1994, to $185,000 due on December 31, 1996.
Interest accrued from January 1, 1994 at 8 percent and was due quarterly. The
remaining unpaid principal balance on the note at December 31, 1995, was
$675,000. The note was paid in full by December 31, 1996.

</TABLE>
 
     At December 31, 1996, the Company had U.S. alternative minimum tax credit
carryforwards, U.S. general business credit carryforwards, and foreign tax
credit carryforwards of approximately $283,000, $560,000 and $305,000,
respectively. The general business credit begins to expire in 2004. The foreign
tax credits expire in 1997 and 1998.
 
     These net operating loss carryforwards and credit carryforwards are
available only to offset future taxable income of the related subsidiary, if
any. Special limitations exist under the tax law that may restrict the
utilization of these net operating loss carryforwards and credits carryforwards
including completion of the initial public offering discussed in Note 17.
 
     The Company expects its effective tax rate to increase after it utilizes
its tax benefit carryovers.

America or other subsidiaries. The majority of the Company's research and
development is performed in its North America segment which includes the
Company's corporate functions. Accordingly, approximately $5.7 million, $7.5
million and $8.0 million in net royalties were paid to the North America segment
during 1994, 1995 and 1996, respectively, by the other operating segments.
Capitalized research and development costs net of accumulated amortization are

employees and directors of the Company or any of its subsidiaries. As of
December 31, 1996 and March 31, 1997, options to purchase an aggregate of 17,300
and 18,800 shares of common stock, respectively, were outstanding under the
Executive Share Option Scheme. Vesting under the Executive Share Option Scheme
occurs over a three year period.
 
STOCK BASED COMPENSATION
 
     The Company accounts for these plans under APB Opinion No. 25, under which
$220,000 was charged to deferred compensation during the year ended December 31,
1996 because certain options were granted at below the then fair market value of
the common stock. This deferred compensation is being amortized over the vesting
period of the related options. No other compensation cost has been recognized
under APB Opinion No. 25 as options have been granted at an option exercise
price equal to the market value of common stock as determined by the Board of
Directors on the date of grant.
 
     Had compensation cost for the plans been determined consistent with SFAS
No. 123, the Company's net income (loss) would have been changed to the
following pro forma amounts:

     Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in future years.

     There are 114,904 options available for grant under the plans at December
31, 1996.
 
     The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 1995 and 1996, respectively: risk-free weighted
average interest rates of 6.5 and 6.2 percent; expected dividend yield of zero
percent; expected life of 5 years from the grant date; expected volatility of 58
percent.
 
12. EXPENSES RELATED TO RESTRUCTURING EUROPEAN OPERATIONS:
 
     In 1990, the Company began reorganizing its activities in Europe in order
to reduce overhead costs. Two offices were closed and certain space in other
offices was vacated, resulting in excess space under lease agreements which
expire December 1999 through December 2014. These facilities are currently
subleased to third parties for periods less than the lease term for which the
Company is obligated. The maximum undiscounted and discounted obligations for
this excess space, net of sublease income as of December 31, 1996, assuming all
contractual sublease break clauses are exercised, are approximately $16.6
million and $7.7 million, respectively, at December 31, 1996. The net maximum
undiscounted and discounted obligations for excess space, assuming that no
sublease break clauses are exercised, are $5.3 million and $2.5 million,
respectively, at December 31, 1996. As of December 31, 1996, the accrual

for excess space related to the reorganization was approximately $500,000. Given
the improvement in the U.K. rental market and recent successes in subletting
space, management believes that the accrual at December 31, 1996 is sufficient.
However, there can be no assurance that the rental market will not be negatively
impacted in the future.
 
13. RELATED-PARTY TRANSACTIONS:
 
     The Company and IBM, a related party, have entered into several marketing
agreements. For the years ended December 31, 1994, 1995 and 1996 and the
quarters ended March 31, 1996 and 1997, the Company incurred marketing expenses
under these agreements of $237,000, $188,000, $32,000, $(68,000) and $25,000,
respectively. Fees payable to IBM as of December 31, 1995 and 1996 and the
quarter ended March 31, 1997 were $378,000, $47,000, and $63,000, respectively,
and are included in other accrued expenses in the accompanying consolidated
balance sheets.
 
     In 1993 and 1996, the Company and IBM entered into development agreements.
Under the 1993 agreement, IBM advanced the Company $200,000 toward the
development of a software product. As of December 31, 1996, the Company had
recognized all revenue under this agreement. Under the 1996 agreement, IBM has
agreed to advance the Company up to $200,000 for the joint development of a
software product. As of December 31, 1996, the Company had received $140,000,
all of which is included in deferred revenue in the accompanying consolidated
balance sheet.
 
     The Company has entered into an agreement to pay a stockholder and a
developer of the Obsydian technology a collective commission of 3 percent
through December 31, 1996 and of 1.5 percent after December 31, 1996 on Obsydian
license and maintenance revenue. Royalties earned by these individuals in the
years ended December 31, 1994, 1995 and 1996 and for the three months ended
March 31, 1996 and 1997 were approximately $66,000, $205,000, $301,000, $47,000
and $42,000, respectively. Royalties accrued at December 31, 1995 and 1996 and
March 31, 1997 were $146,000, $184,000, and $114,000, respectively.
 
14. COMMITMENTS AND CONTINGENCIES:
 
     The Company has entered into employment agreements with three key employees
providing for the payment of up to one year's salary and certain bonus amounts
in the event of termination or a change in control of the Company.
 
15. RETIREMENT PLAN:
 
     The Company participates in an employee savings and retirement 401(k) plan
which covers all full-time employees who are at least 21 years of age. Employees
may elect to contribute up to 15% of their compensation (subject to statutory
limitations) to the Plan. The Company, at its discretion, may provide a matching
contribution in an amount as determined by the Board of Directors. To date the
Company has made no matching contributions.
 
16. LITIGATION:
 
     The Company is involved in various litigation matters arising during the
normal course of its business. The Company intends to defend these matters, and
it is management's opinion that the ultimate outcome of these matters will not
have a material adverse effect on the Company's operations or financial
position.

1,500,000 shares, 400,000 shares, and 175,000 shares have been reserved for
issuance under these Plans, respectively. Each of these Plans provides for an
annual increase in the number of shares reserved for issuance.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.
 
     The Registrant's Amended and Restated Certificate of Incorporation provides
for the indemnification of directors to the fullest extent permissible under
Delaware law.
 
     The Registrant's Bylaws provide for the indemnification of officers,
directors and third parties acting on behalf of the Registrant if such person
acted in good faith and in a manner reasonably believed to be in and not opposed
to the best interest of the Registrant, and, with respect to any criminal action
or proceeding, the indemnified party had no reason to believe his conduct was
unlawful.
 
     The Registrant has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for in
the Registrant's Bylaws, and intends to enter into indemnification agreements
with any new directors and executive officers in the future.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     Since May 22, 1994, the Registrant has issued and sold 156,338 shares of
its Common Stock to employees for an aggregate amount of $159,648.08 pursuant to
the exercise of options under its 1990 Stock Option Plan and Executive Share
Option Scheme.
 
     The share amounts set forth above take into account the one-for-two reverse

ITEM 17. UNDERTAKINGS
 
     The Registrant hereby undertakes to provide the Underwriters at the closing
specified in the Underwriting Agreement certificates in such denominations and
registered in such names as required by the Underwriters to permit prompt
delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described in Item 14 above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer, or
controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933, and will be governed by the final adjudication of such
issue.
 
     The undersigned Registrant undertakes that: (1) for purposes of determining
any liability under the Securities Act of 1933, the information omitted from the
form of prospectus as filed as part of the registration statement in reliance
upon Rule 430A and contained in the form of prospectus filed by the Registrant
pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be
deemed to be part of this registration statement as of the time it was declared
effective, and (2) for the purpose of determining any liability under the
Securities Act of 1933, each posteffective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

Registrant has duly caused this Registration Statement on Form S-1 to be signed

                              AMENDED AND RESTATED

                          CERTIFICATE OF INCORPORATION

                                       OF

                               SYNON CORPORATION

       (Pursuant to Section 245 of the Delaware General Corporation Law)

                 Paul Wilde and Mark A. Bertelsen hereby certify that:

         1.      They are the Vice President and Assistant Secretary of Synon
Corporation, a Delaware Corporation.

         2.      The Certificate of Incorporation of this corporation,
originally filed with the Secretary of State of Delaware on May 11, 1990, is
hereby amended and restated in its entirety to read as follows:

"FIRST:          The name of the Corporation is Synon Corporation (the
                 "Corporation").

SECOND:          The address of the Corporation's registered office in the
                 State of Delaware is Corporation Trust Center, 1209 Orange
                 Street, in the City of Wilmington, County of New Castle, Zip
                 Code 19801.  The name of its registered agent at such address
                 is The Corporation Trust Company.

THIRD:           The purpose of the Corporation is to engage in any lawful act
                 or activity for which corporations may be organized under the
                 General Corporation Law of Delaware.

FOURTH:          This Corporation is authorized to issue two classes of shares
                 to be designated, respectively, Common Stock and Preferred
                 Stock.  The total number of shares of Common Stock this
                 Corporation shall have authority to issue is 25,000,000 and
                 the total number of shares of Preferred Stock this Corporation
                 shall have authority to issue is 10,000,000.  The par value of
                 the Common Stock and the Preferred Stock shall be $0.001. Upon
                 the filing of this Amended and Restated Certificate of
                 Incorporation, each share of Series B Preferred Stock
                 outstanding immediately prior to the filing of this Amended
                 and Restated Certificate of Incorporation shall be
                 reconstituted as and converted into 0.48394 shares of Series D
                 Preferred Stock with the rights, preferences, privileges and
                 restrictions set forth herein, and each share of Series C
                 Preferred Stock outstanding immediately prior to the filing of
                 this Amended and Restated Certificate of Incorporation shall
                 be reconstituted as and converted into 0.1906433 shares of
                 Series A Preferred Stock with the rights, preferences,
                 privileges and restrictions set forth herein.  No fractional
                 shares shall be issued upon such reconstitution and conversion
                 of the Series B and Series C Preferred Stock.  In lieu of any
                 fractional shares to which the holder would otherwise be
                 entitled, the corporation shall pay cash equal to such
                 fraction multiplied by the conversion price applicable to the
                 shares being reconstituted and converted immediately prior to
                 the filing of this Amended and Restated Certificate of
                 Incorporation.

                 The Preferred Stock may be issued from time to time in one or
                 more series.  A portion of the Preferred Stock shall initially
                 be designated as two series, namely, Series A Preferred Stock
                 (the "Series A Preferred"), consisting of 2,554,620 shares,
                 and Series D Preferred Stock (the "Series D Preferred"),
<PAGE>   2
                 consisting of 3,618,269 shares.  The Board of Directors is
                 hereby authorized to fix or alter the dividend rights,
                 dividend rate, conversion rights, voting rights, rights and
                 terms of redemption (including sinking fund provisions),
                 redemption price or prices, and liquidation preferences of any
                 wholly unissued series of Preferred Stock, and the number of
                 shares constituting any such series and the designation
                 thereof, or any of them.

                 The Board of Directors is further authorized to increase or
                 decrease (but not below the number of shares thereof then
                 outstanding) the number of shares of any series, the number of
                 which was fixed by it, subsequent to the issue of shares of
                 such series then outstanding, subject to the limitations and
                 restrictions stated in the Certificate of Incorporation or the
                 resolution of the Board of Directors originally fixing the
                 number of shares of such series.  If the number of shares of
                 any series is so decreased, then the shares constituting such
                 decrease shall resume the status which they had prior to the
                 adoption of the resolution originally fixing the number of
                 shares of such series.

                 The Corporation shall from time to time in accordance with the
                 laws of the State of Delaware increase the authorized amount
                 of its Common Stock if at any time the number of shares of
                 Common Stock remaining unissued and available for issuance
                 shall not be sufficient to permit conversion of the Series A
                 Preferred and Series D Preferred.

         The relative rights, preferences, privileges and restrictions granted
to or imposed on the respective classes of the shares of capital stock or the
holders thereof are as follows:

         1.      Dividends.  The holders of Series A Preferred, Series D
Preferred and Common Stock shall be entitled to receive dividends on a pari
passu basis when and as declared by the Board of Directors, out of funds
legally available therefor.  Such dividends shall not be cumulative and no
right to such dividends shall accrue to holders of the Preferred Stock and
Common Stock except as declared by the Board of Directors.

         2.      Liquidation Preference.  In the event of any liquidation,
dissolution, or winding up of the Corporation, either voluntary or involuntary,
distributions to the stockholders of the Corporation shall be made in the
following manner:

                 (a)      First, holders of Series D Preferred shall be
entitled to receive, prior and in preference to any distribution of any of the
assets or surplus funds of the Corporation to the holders of the Corporation's
other stock, the amount of $3.35 per share and, in addition, an amount equal to
any declared but unpaid dividends on the Series D Preferred shares then held by
them.  If the assets and funds thus distributed among the holders of the Series
D Preferred shall be insufficient to permit the payment to such holders of the
full aforesaid preferential amount, then the entire assets and funds of the
Corporation legally available for distribution shall be distributed ratably
among the holders of the Series D Preferred based on the number of shares of
Series D Preferred held.

                 (b)      Second, holders of Series A Preferred shall be
entitled to receive, prior and in preference to any distribution of any of the
assets or surplus funds of the Corporation to the holders of the Corporation's
Common Stock, the amount of $8.503194 per share and, in addition, an amount
equal to any declared but unpaid dividends on the Series A Preferred shares
then held by them. If, after payment has been made to the holders of Series D
Preferred of the full amounts to which they shall be entitled as aforesaid, the
assets and funds thus distributed among the holders of the Series A Preferred
shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amount, then the remaining assets and funds of the
corporation legally available for
<PAGE>   3
distribution shall be distributed ratably among the holders of the Series A
Preferred based on the number of shares of Series A Preferred held.

                 (c)      Third, holders of Series D Preferred and Common Stock
shall be entitled to receive the amount of $8.503194 per share and, in
addition, an amount equal to any declared but unpaid dividends on the Series D
Preferred or Common Stock shares then held by them.  If, after payment has been
made to the holders of Series D Preferred and Series A Preferred of the full
amounts to which they shall be entitled pursuant to subsections (a)-(b) above,
the assets and funds thus distributed among the holders of the Series D
Preferred and Common Stock pursuant to this subsection (c) shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amount, then the remaining assets and funds of the Corporation
legally available for distribution shall be distributed ratably among the
holders of the Series D Preferred and Common Stock based on the number of
shares of Common Stock held, assuming conversion of the Series D Preferred into
Common Stock.

                 (d)      After payment has been made to the holders of
Preferred Stock and Common Stock as discussed above in subsections (a)-(c),
the holders of Series A Preferred, Series D Preferred and Common Stock shall be
entitled to share ratably in the remaining assets and funds of the Corporation
based on the number of shares of Common Stock held, assuming conversion of the
Series A Preferred and Series D Preferred into Common Stock.

                 (e)      For purposes of this Section 2, a merger or
consolidation of the Corporation with or into any other corporation or
corporations, or a sale of all or substantially all of the assets of the
Corporation, shall be treated as a liquidation, dissolution or winding up of
the Corporation, unless the stockholders of the Corporation hold at least 50%
of the outstanding voting equity securities of the surviving corporation in
such merger, consolidation or sale of assets reorganization.

                 (f)      Each holder of an outstanding share of Preferred
Stock shall be deemed to have consented, for all purposes, to distributions
made by the Corporation in connection with the repurchase of shares of Common
Stock issued to or held by employees or consultants upon termination of their
employment or services pursuant to agreements providing for the right of said
repurchase between the Corporation and such persons.

         3.      Voting Rights.

                 (a)      General Voting.  Except as otherwise required by law,
the holder of each share of Common Stock shall be entitled to one vote and the
holder of each share of Preferred Stock shall be entitled to the number of
votes equal to the number of shares of Common Stock into which the Preferred
Stock could be converted at the record date for determination of the
stockholders entitled to vote on such matters, or, if no such record date is
established, at the date such vote is taken or any written consent of
stockholders is solicited, and, except as otherwise expressly provided herein
or required by law, such votes to be counted together with all other shares of
stock of the Corporation having general voting power and not separately as a
class.

                 (b)      Notice; Fractional Shares.  Holders of Common Stock
and Preferred Stock shall be entitled to notice of any stockholders' meeting in
accordance with the Bylaws of the Corporation.  Fractional votes by the holders
of Preferred Stock shall not, however, be permitted and any fractional voting
rights resulting hereunder (after aggregating all shares into which shares of
Preferred Stock held by each holder could be converted) shall be rounded to the
nearest whole number.

         4.      Conversion.  The holders of the Preferred Stock have
conversion rights as follows:

                 (a)      Right to Convert.





<PAGE>   4
                           (i)    Series A Preferred. Each share of Series A
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share, into one fully paid and
nonassessable share of Common Stock.

                          (ii)    Series D Preferred.  Each share of Series D
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share, into one fully paid and
nonassessable share of Common Stock and, in addition, the amount of $3.35 in
cash or, at the election of the Corporation, equity securities of the
Corporation with an agreed-upon or appraised market value of $3.35 (such cash
or securities equivalent to $3.35 referred to herein as the "Series D
Conversion Consideration"). In the event the Corporation elects to issue
securities with an appraised market value of $3.35, such appraisal shall be
made by the Corporation's independent auditors, by a party selected by the
Corporation's independent auditors or by a party otherwise acceptable to the
Corporation and to the holder converting such shares of Series D Preferred
Stock.

                 (b)      Automatic Conversion.  Each share of Series A
Preferred Stock shall automatically be converted into one share of Common Stock
and each share of Series D Preferred Stock shall automatically be converted
into one share of Common Stock and, in addition, the Series D Conversion
Consideration upon the occurrence of any of the following events: (A) the
closing of a firm commitment, underwritten public offering pursuant to an
effective registration statement under the Securities Act of 1933, as amended,
covering the offer and sale of Common Stock of the Corporation to the public at
a minimum price per share (prior to underwriting commissions and offering
expenses) of $10.00 per share (appropriately adjusted for any stock split,
stock dividend, combination, recapitalization or similar event) and an
aggregate gross offering price of not less than $10,000,000; or (B) the
approval of such conversion by the vote of holders of more than 50% of the
aggregate number of outstanding shares of Preferred Stock.  In the event of the
automatic conversion of the Preferred Stock upon a public offering as
aforesaid, the person(s) entitled to receive the Common Stock and, in the case
of holders of Series D Preferred Stock, the Series D Conversion Consideration
issuable upon such conversion of Preferred Stock shall not be deemed to have
converted such Preferred Stock until immediately prior to the closing of such
sale of securities.

                         (iii)    Mechanics of Conversion.  No fractional
shares of Common Stock shall be issued upon conversion of the Preferred Stock.
In lieu of any fractional shares to which the holder would otherwise be
entitled, the Corporation shall pay cash equal to such fraction multiplied by
the fair market value of the Common Stock as determined by the Board of
Directors.  Before any holder of Preferred Stock shall be entitled to convert
the same into full shares of Common Stock, to receive certificates therefor
and, in the case of holders of Series D Preferred Stock, to receive the Series
D Conversion Consideration, he or she shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of
any transfer agent for the Preferred Stock, and shall give written notice to
the Corporation at such office that he or she elects to convert the same;
provided, however, that in the event of an automatic conversion pursuant to
Section 4(a)(ii)), the outstanding shares of Preferred Stock shall be converted
automatically without any further action by the holders of such shares and
whether or not the certificates representing such shares are surrendered to the
Corporation or its transfer agent and provided further that the Corporation
shall not be obligated to issue certificates evidencing conversion and, in the
case of Series D Preferred Stock, to issue the Series D Conversion
Consideration unless the certificates evidencing such shares of Preferred Stock
are either delivered to the Corporation or its transfer agent as provided
above, or the holder notifies the Corporation or its transfer agent that such
certificates have been lost, stolen or destroyed and executes an agreement
satisfactory to the Corporation to indemnify the Corporation from any loss
incurred by it in connection with such certificates.  The Corporation shall, as
soon as practicable after such delivery, issue and deliver at such office to
such holder of Preferred Stock, a certificate or certificates for the number of
shares of Common Stock to which such holder shall be entitled as aforesaid, a
check payable to the holder in the amount of any cash amounts payable as the
result of a conversion into fractional shares of Common Stock and, in the
<PAGE>   5
case of holders of Series D Preferred Stock, the Series D Conversion
Consideration.  Such conversion shall be deemed to have been made immediately
prior to the close of business on the date of such surrender of the shares of
Preferred Stock to be converted, or in the case of automatic conversion on the
date of closing of the public offering or on the date agreed upon by the
stockholders approving a conversion, and the person or persons entitled to
receive the shares of Common Stock and, in the case of Series D Preferred
Stock, the Series D Conversion Consideration issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such
shares of Common Stock and, in the case of holders of Series D Preferred Stock,
such Series D Conversion Consideration on such date.

         5.      Preemptive Rights.

                 (a)      All shares of capital stock, including securities
convertible into capital stock, which the Corporation proposes to issue (other
than issuances in accordance with subsection (b) below) shall first be offered
to the Corporation's stockholders pro rata based on their share ownership of
Common Stock and Preferred Stock.  The offer shall be made by notice specifying
the number of shares offered, and limiting a period (not less than fourteen
days) within which the offer, if not accepted, will be deemed to be declined.
After the expiration of such period, those shares deemed to be declined shall
be offered pro rata to the persons who have, within the said period, accepted
all the shares offered to them; such further offer shall be made on the same
terms and in the same manner as the original offer.  Any shares not accepted
pursuant to such offer or further offer as aforesaid shall be under the control
of the Corporation who may allot, grant options over or otherwise dispose of
the same to such persons, on such terms, and in such manner as it thinks fit,
provided however that such shares shall not be disposed of on terms which are
more favorable to the subscribers therefor than the terms on which they were
offered to the stockholders of the Corporation.

                 (b)      The preemptive rights contained in Section 5(a) above
shall not apply to or in respect of the issuance of or grant of options over
shares in the Corporation as follows:

                           (i)    pursuant to any stock benefit plan or stock
option agreement approved by the Board of Directors;

                          (ii)    pursuant to an acquisition of shares in the
Corporation's subsidiaries in exchange for shares in the Corporation;

                         (iii)    any shares of Common Stock issued upon the
conversion of shares of Preferred Stock pursuant to Section 4 of this Article;

                          (iv)    any shares of Series D Preferred Stock;

                           (v)    pursuant to a public offering pursuant to an
effective registration statement under the Securities Act of 1933, as amended;

                          (vi)    pursuant to any sales, technology license or
distribution agreements or other strategic relationships approved by the Board
of Directors; or

                         (vii)    pursuant to any acquisition approved by the
Board of Directors in exchange for shares in the Corporation, provided that the
number of shares to be exchanged does not exceed 15% of the total number of
shares of Series A Preferred, Series D Preferred and Common Stock of the
Corporation outstanding at the time of such acquisition.

                 (c)      The provisions of this Section 5 may be amended only
by the approval of the holders of seventy-five percent (75%) of the Common
Stock and Preferred Stock voting together.
<PAGE>   6
                 (d)      Notwithstanding the foregoing, the preemptive rights
granted pursuant to this Section 5 shall terminate upon the earlier to occur of
the closing of a firm commitment underwritten public offering registered under
the Securities Act of 1933, as amended, or such time as the corporation is
required to file reports pursuant to Sections 13 or 15(d) of the Securities
Exchange Act of 1934, as amended.

         6.      Covenants.  In addition to any other rights provided by law,
the following covenants apply with regard to the holders of the Corporation's
securities:

                 (a)      so long as any Series A Preferred or Series D
Preferred shall be outstanding, this Corporation shall not, without first
obtaining the affirmative vote of the holders of a majority of such outstanding
shares of Series A and Series D Preferred voting together:

                           (i)    effect a split or reverse-split on the Common
Stock,

                          (ii)    amend or repeal any provision of, or add any
provision to, this Corporation's Certificate of Incorporation if such action

("Series D Preferred") and 1,666,667 shall be designated Series E Preferred
Stock ("Series E Preferred").  The total number of shares or Common Stock which
the Corporation shall have the authority to issue is 25,000,000.

         The Board of Directors is hereby authorized to fix or alter the
dividend rights, dividend rate, conversion rights, voting rights and
liquidation preferences of any wholly unissued series of Preferred Stock (to
the extent such terms of the series do not impair any term accorded to any
outstanding series of Preferred Stock), and the number of shares constituting
any such series and the designation thereof, or any of them to the extent such
terms are otherwise consistent with the other provisions hereof.  No such
series or
<PAGE>   12

or term accorded any existing series of Preferred Stock, (ii) grants any
liquidation preference on parity with or superior to the Series E Preferred
stock, (iii) initially authorizes any series with voting rights or dividend

one share of Common Stock or otherwise provides for disproportionate conversion
privileges.

         The Board of Directors is further authorized to increase or decrease
(but not below the number of shares thereof then outstanding) the number of
shares of any series (other than any existing series), the number of which was
fixed by it, subsequent to the issuance of shares at such series then
outstanding, subject to the limitations and restrictions stated in the
Certificate of Incorporation or the resolution of the Board of Directors
originally fixing the number of shares of such series.  If the number of shares
of any series is so decreased, then the shares constituting such decrease shall
resume the status which they had prior to the adoption of the resolution
originally fixing the number of shares of such series.

         The Corporation shall from time to time in accordance with the laws of
the State of Delaware increase the authorized amount of its Common Stock if at
any time the number of shares of Common Stock remaining unissued and available
for issuance shall not be sufficient to permit conversion or the Series A
Preferred, Series D Preferred and Series E Preferred.

number of shares of fully paid and nonassessable Common Stock (calculated as to
each conversion to the nearest 1/100th of a share) obtained by dividing $3.35
by the Series D Conversion Price plus (B) the amount at $3.35 in cash out of
assets of the Corporation legally available for payment to shareholders or at
the election of the
<PAGE>   17
Corporation equity securities of the Corporation with an agreed-upon or
appraised market value of $3.35 (such cash or securities equivalent to $3.35
referred to herein as the "Series D Conversion Consideration").  In the event
the Corporation elects to issue securities with an appraised market value of
$3.35, such appraisal shall be made by an independent, nationally recognized
investment banking firm selected by the Corporation and the holders of a
plurality of the shares of Series D Preferred being converted; provided that if
such parties cannot agree on the selection of an investment banker, the
Corporation and the holders of a plurality of the shares of Series D Preferred
being converted shall each select one nationally recognized investment banking
firm, and the firms thus selected shall jointly select a third nationally
recognized investment banking firm which shall determine such fair market
value.

                         (iii)    Each share of Series A Preferred shall
automatically be converted into Common Stock and each share of Series D
Preferred shall automatically be converted into Common Stock, using the
applicable Conversion Price, upon the closing of a public offering on an
underwritten firm commitment basis pursuant to a registration statement filed
and declared effective by the Securities and Exchange Commission pursuant to
the Securities Act of 1933, as amended (the "Securities Act"), covering the
offer and sale by the Company of Common Stock at a per share price (as adjusted
for recapitalizations, stock splits, stock dividends and the like) of at least
$5 per share, which public offering results in gross cash proceeds to the
Company of at least $10 million dollars (the "Initial Public Offering"). In the
event of the automatic conversion of the Series A Preferred and the Series D
Preferred upon an Initial Public Offering as aforesaid, the person(s) entitled
to receive the Common Stock and, in the case of holders of Series D Preferred,
the Series D Conversion Consideration issuable upon such conversion of
Preferred Stock, shall not be deemed to have converted such Preferred Stock
until immediately prior to the closing of such sale of securities.

                          (iv)    Each share of Series E Preferred shall
automatically be converted into Common Stock, using the Series E Conversion
Price, upon the Company's Initial Public Offering.  In the event of the
automatic conversion of the Series E Preferred upon an Initial Public Offering
as aforesaid, the person(s) entitled to receive the Common Stock
<PAGE>   18
shall not be deemed to have converted such Preferred Stock until immediately
prior to the closing of such sale of securities.

                 (b)      Conversion Procedures. in order to exercise the
conversion privilege under Sections 5(a)(i) and (ii), the holder of any shares
of Preferred Stock of any series to be converted shall surrender the
certificate representing such shares at the principal office of the
Corporation, with a written notice stating that such holder elects to convert
all or a specified whole number of such shares pursuant to this Section 5 and
specifying the name or names in which such holder wishes the certificate or
certificates for Conversion Shares, and, in the case of Series D Preferred
Stock, certificates representing the Series D Conversion Consideration, to be
issued.  Unless the conversion Shares (and, if applicable, securities
representing the Series D Conversion Consideration) are to be issued in the
same name as the name in which such shares if Preferred Stock are registered,
the certificate representing the shares surrendered for conversion shall be
accompanied by instruments of transfer, in form satisfactory to the
Corporation, duly executed by the holder or its duly authorized attorney.  In
the event or an automatic conversion pursuant to Section 5(a)(iii) or 5(a)(iv),
the outstanding shares of Series A Preferred, Series D Preferred and Series E
Preferred shall be converted automatically without any further action by the
holders of such shares and whether or not the certificates representing such
shares are surrendered to the Corporation or its transfer agent, provided that
the Corporation shall not be obligated to issue certificates evidencing the
shares of Common Stock issuable upon such automatic conversion unless the
certificates evidencing such shares of Preferred Stock are either delivered to
the Corporation or its transfer agent, or the holder notifies the Corporation
or its transfer agent that such certificates have been lost, stolen or
destroyed and executes an agreement satisfactory to the Corporation to
indemnify the Corporation from any loss incurred by it in connection with such
certificates. As promptly as practicable after such surrender of a certificate
for shares of Preferred Stock of any series to be converted, and in any event
within five business days (as defined below) thereafter, the Corporation shall
issue and deliver at such office to such holder, or on such holder's written
order, (i) a certificate or certificates for the applicable number of full
Conversion Shares, (ii) if
<PAGE>   19
less than the full number of shares of Preferred Stock evidenced by the
surrendered certificate is being converted, a new certificate, of like tenor,
for the number of shares of Preferred Stock of the applicable series evidenced
by such surrendered certificate less the number of shares being converted and
(iii) the cash payment in settlement of any fractional Conversion Share
provided for in Section 5(c). Upon conversion of any shares of Preferred Stock,
the holder thereof shall be entitled to receive an amount equal to all declared
and unpaid dividends an such shares. A "business day" is a day other than a
Saturday, Sunday or legal holiday in the State or New York or the State of
California, on which banks are open for business in New York, New York and San
Francisco, California.

         In the case of (x) the exercise of the conversion privilege under
5(a)(i) and 5(a)(ii), each conversion shall be deemed to have been effected
(subject, in the case of the Series D Preferred, to Section 5(a)(ii)) as of the
close of business on the date on which the certificate for shares of Preferred
Stock to be converted is surrendered and such notice is received by the
Corporation as aforesaid and (y) automatic conversion pursuant to Sections
5(a)(ii) or 5(a)(iv) the Conversion shall be deemed to have been effected as of
immediately prior to the closing of the Initial Public Offering, and the person
or persons in whose name or names any certificate or certificates for
Conversion Shares (and, if applicable, securities representing Series D
Conversion Consideration) are issuable shall be deemed to have become the
holder or holders of record of such Conversion Shares (and, if applicable,
securities representing Series D Conversion Consideration) at such time on such
date and, in the case of the Series A Preferred and Series E Preferred, such
conversion shall be at the applicable Conversion Price in effect at such time
on such date, unless the stock transfer books of the Corporation are closed an
that date, in which event such person or persons shall be deemed to have become
such holder or holders of record at the close of business an the next day on
which such stock transfer books are open (provided that if such books shall
remain closed for five days, such fifth day shall be the date any such person
shall become such a holder), but such conversion shall be at the Conversion
Price in effect on the date on which such certificate was surrendered and such
notice was received. Upon delivery, all Conversion Shares shall be duly
authorized,
<PAGE>   20
validly issued, fully paid, nonassessable, free of all liens and charges and
not subject to any preemptive or subscription rights.

                 (c)      Settlement of Fractional Conversion Shares.  No
fractional Conversion Shares or scrip representing fractions of Conversion
Shares shall be issued upon conversion of shares of Preferred Stock of any
series.  Instead of any fractional Conversion Share otherwise deliverable, the
Corporation shall pay to the holder of the converted shares an amount in cash
equal to the current market price (as defined below) at such fractional
Conversion Share on the date of conversion. If more than one share in
surrendered for conversion at one time by the same holder, the number of full
Conversion Shares shall be computed an the basis of the aggregate number of
shares so surrendered. The "current market price" per share of Common Stock on
any day is the average of the daily market prices for the 30 consecutive
trading days immediately prior to the day in question.  The "daily market
price" of a share of Common Stock is the price of a share of Common Stock on
the relevant day, determined on the basis of the last reported sale price,
regular way, of the Common Stock as reported on the composite tape, or similar
reporting system, for issues listed or admitted to trading on the New York
Stock Exchange (or if the Common Stock is not then listed or admitted to
trading on the New York Stock Exchange, on the principal national securities
exchange on which the Common Stock is then listed or admitted to trading) or on
the National Association of Securities Dealers Automated Quotation System
National Market System or, if there is no such reported sale on the day in
question, on the basis of the average of the closing bid and asked quotations
as so reported or, it the Common Stock is not then listed or admitted to
trading on any national securities exchange or on the National Association of
Securities Dealers Automated Quotation System National Market System, on the
basis of the average of the high bid and low asked quotations on the day in
question in the over-the-counter market as reported by the National Association
of Securities Dealers Automated Quotation System, or, if not so quoted, as
reported by National Quotation Bureau, Incorporated, or a similar organization.
If the current market price is not determinable as aforesaid, it shall be
determined in good faith by the Board and evidence of such determination shall
be filed with the minutes of the Corporation.  A "trading day" is a day on
which the principal national securities
<PAGE>   21
exchange on which the Common Stock is listed or admitted to trading is open for
the transaction of business or, if the Common Stock is not then listed or
admitted to trading on any national securities exchange, any day other than
Saturday, Sunday or a federal holiday.

                 (d)      The "Series A Conversion Price" shall mean $8.503194,
the "Series D Conversion Price" shall mean $3.35 and the "Series E Conversion
Price" shall mean $3.00, in each case as adjusted pursuant to this Section
5(d). "Conversion Price" shall generally mean the Series A Conversion Price,
the Series D Conversion Price or the Series E Conversion Price, as applicable.
The Series A Conversion Price, the Series D Conversion Price and the Series E
Conversion Price (and the kind and amount of consideration receivable by
holders of shares of Series A Preferred, Series D Preferred or Series E
Preferred upon conversion) shall be adjusted from time to time as follows:

                           (i)    If after the date of issuance of the Series E
Preferred the Corporation (A) pays a dividend or makes a distribution on the
Common Stock in shares of Common Stock, (B) subdivides or combines its
outstanding shares of Common Stock into a greater or smaller number of shares
or (C) issues by reclassification of the Common Stock any shares of capital
stock of the Corporation, each Conversion Price in effect immediately prior to
such action shall be adjusted so that the holder of any share of Series A
Preferred, Series D Preferred or Series E Preferred thereafter surrendered for
conversion shall be entitled to receive, at the time of such conversion, the
number of shares of Common Stock or other capital stock of the Corporation that
it would have owned or been entitled to receive immediately following such
action had such share been converted immediately prior to such action or the
record date therefor, whichever is earlier.  Such adjustment shall become
effective immediately after the record date, in the case of a dividend or
distribution, or immediately after the effective date, in the case of a
subdivision, combination or reclassification.

                          (ii)    If the corporation issues any Additional
Shares (as defined below) for a consideration per share less than the Series E
Conversion Price in effect immediately prior to such issuance, then (A) if the
date of issuance of such Additional Shares is before 18 months after the date
of issuance of the Series E Preferred, the
<PAGE>   22
Series E Conversion Price shall be adjusted to equal the consideration per
share for which such Additional Shares are issued, and (B) if the date of
issuance of such Additional Shares is on or after 18 months after the date of
issuance of the Series E Preferred, the Series E Conversion Price shall be
adjusted by multiplying the Series E Conversion Price in effect immediately
prior to such issuance by a fraction (I) the numerator of which shall be the
number of shares of Common Stock and Share Equivalents outstanding immediately
prior to the issuance of such Additional Shares plus the number of shares of
Common Stock that the aggregate consideration for such Additional Shares would
purchase at a consideration per share equal to such Conversion Price and (II)
the denominator of which shall be the number of shares of Common Stock and
Share Equivalents outstanding immediately prior to the issuance of such
Additional Shares plus the number of Additional Shares so issued.  Such
adjustment for the Series E Preferred shall become effective immediately after
the issuance of such Additional Shares but prior to any adjustment for such
Additional Shares to the Series D Conversion Price.  For the purpose of this
Section 5 the reissuance or resale of any Additional Shares or other Rights (as
defined below) or Convertible Securities (as defined below) shall also result
in an adjustment to the Series E Conversion Price to the extent an appropriate
adjustment under Section 5(d)(vii) has been made.

         "Additional Shares" shall mean any shares of Common Stock of the
Corporation issued by the Corporation after the date of issuance of the Series
E Preferred excluding Permitted Issuances.  "Share Equivalents" shall mean the
Common Stock deliverable upon conversion or exercise of all outstanding
Preferred Stock, convertible securities, optional warrants and rights of the
Corporation as of the date such computation is made and as of the time such
computation is effective as specified herein.

         "Permitted Issuances" shall mean (i) any employee stock options which
have been granted and remain unexercised as of the date of issuance of the
Series E Preferred, (ii) employee stock options granted and shares issued to
employees and consultants after the issuance at the Series E Preferred in the
aggregate amount of 585,750 shares of Common Stock pursuant to the Corporation's
stock plans, (iii) additional employee options granted and shares issued in an
amount equal to options granted and shares issued pursuant to the
<PAGE>   23
foregoing clauses (i) and (ii) to the extent such shares are returned to the
Corporation's stock plans upon the lapse of unexercised stock options or the
repurchase (at original purchase price) of unvested shares (iv) any shares
issued upon exercise of options granted pursuant to the foregoing clauses
(i)-(iii), provided that the total of all such options outstanding, shares
issued upon exercise of such options and shares sold pursuant to clauses (i)
through (iv) shall never exceed 2,920,763, (v) any shares issued upon
conversion of the Series A Preferred, Series D Preferred and Series E Preferred
(including adjustments to the conversion ratio) and (vi) any other stock
options granted and shares issued upon the exercise thereof approved by the
holders of a majority or the Series E Preferred, which approval shall not be
unreasonably withheld, and any shares issued to the holders of the Series E
Preferred in connection with any contractual rights, related to such approved
shares or options.

                         (iii)    If after the date of issuance of the Series E
Preferred the Corporation issues any warrants, options or other rights
entitling the holders thereof to subscribe for or purchase either any
Additional Shares or evidences of debts, shares of capital stock or other
securities that are convertible into or exchangeable for, with or without
payment of additional consideration, Additional Shares (such warrants, options
or other rights being called "Rights" and such convertible or exchangeable
evidences of debt shares of capital stock or other securities being called
"Convertible Securities"), and the consideration per share for which Additional
Shares may at any time thereafter be issuable pursuant to such Rights or
Convertible Securities (when added to the consideration per share of Common
Stock, if any, received for such Rights) is less than the Series E Conversion
Price, the Series E Conversion Price shall be adjusted as provided in Section
5(d)(ii) on the basis that (A) the maximum number of Additional Shares issuable
pursuant to all such Rights or necessary to effect the conversion or exchange
of all such Convertible Securities shall be deemed to have been issued and (B)
the aggregate consideration (plus the consideration, if any, received for such
Rights) for such maximum number of Additional Shares shall be deemed to be the
consideration received and receivable by the Corporation for the issuance of
such Additional Shares pursuant to such Rights or Convertible Securities.
<PAGE>   24
                          (iv)    If after the date of issuance of the Series E
Preferred the Corporation issues Convertible Securities and the consideration
per share for which Additional Shares may at any time thereafter be issuable
pursuant to such Convertible Securities is less than the Series E Conversion
Price, the Series E Conversion Price shall be adjusted as provided in Section
5(d)(ii) on the basis that (A) the maximum number of Additional Shares
necessary to effect the conversion or exchange of all such Convertible
Securities shall be deemed to have been issued and (B) the aggregate
consideration for such maximum number of Additional Shares shall be deemed to
be the consideration received and receivable by the Corporation for the
issuance of such Additional Shares pursuant to such Convertible Securities.  No
adjustment of the Series E Conversion Price shall be made under this Section
5(d)(iv) upon the issuance or any Convertible Securities issued pursuant to the
exercise of any Rights, to the extent that such adjustment was previously made
upon the issuance of such Rights pursuant to Section 5(d)(iii).

                           (v)    For purposes of Sections 5(d)(iii) and
5(d)(iv), the relevant Series E Conversion Price shall be the Series E
Conversion Price in effect immediately prior to the earlier of (A) the record
date for the holders of Common Stock entitled to receive the Rights or
Convertible Securities and (B) the initial issuance of the Rights or
Convertible Securities, and the adjustment provided for in either such Section
shall become effective immediately after the earlier of the times specified in
clauses (A) and B).

                          (vi)    No adjustment of the Series E Conversion
Price shall be made under Section 5(d)(ii) upon the issuance of any Additional
Shares pursuant to the exercise of any Rights or of any conversion or exchange
rights pursuant to any Convertible Securities, if such adjustment was
previously made in connection with the issuance of such Rights or Convertible
Securities (or in connection with the issuance of any Riqhts therefor) pursuant
to Section 5(d)(iii) or 5(d)(iv).

                         (vii)    If any Rights (or any portions thereof) that
gave rise to an adjustment pursuant to Section 5(d)(iii) or any conversion or
exchange rights pursuant to any Convertible Securities that gave rise to an
adjustment pursuant to Section 5(d)(iii) or 5(d)(iv) expire or terminate
without the exercise thereof and/or if by reason of the
<PAGE>   25
provisions of such Rights or Convertible Securities there has been any
increase, with the passage of time or otherwise, in the consideration payable
upon the exercise thereof, the Series E Conversion Price shall be readjusted
(but to no greater extent than originally adjusted) on the basis of (A)
eliminating from the computation Additional Shares corresponding to such
expired or terminated Rights or conversion or exchange rights, (B) treating the
Additional Shares, if any actually issued or issuable pursuant to the previous
exercise of such Rights or conversion or exchange rights as having been issued
for the consideration actually received and receivable therefor and (C)
treating any such Rights or conversion or exchange rights that remain
outstanding as being subject to exercise on the basis of the consideration
payable upon the exercise or conversion thereof as is in effect at such time;
provided, however, that any consideration actually received by the Corporation
in connection with the issuance of such Rights shall form part of the
readjustment computation even though such Rights expired without being
exercised.  The Series E Conversion Price shall be adjusted as provided in
Section 5(d)(ii) and any applicable provisions of Section 5(d)(iii) or 5(d)(iv)
as a result of any increase in the number of Additional Shares issuable, or any
decrease in the consideration payable upon any issuance of Additional Shares,
pursuant to any antidilution provisions of any Rights or Convertible
Securities.

                        (viii)    If after the date of Issuance of the Series E
Preferred, the Corporation issues any Additional Shares for a consideration per
share less than the Series D Conversion Price in effect immediately prior to
such issuance, then (A) if the date of issuance of such Additional Shares is
before 18 months after the date of issuance of the Series E Preferred, the
Series D Conversion Price shall be adjusted to equal the consideration per
share for which such Additional Shares are issued, and (B) if the date of
issuance of such Additional Shares is on or after 18 months after the date of
issuance of the Series E Preferred, the Series D Conversion Price shall be
adjusted by multiplying the Series D Conversion Price in effect immediately
prior to such issuance by a fraction (I) the numerator at which shall be the
number of shares of Common Stock and Share Equivalents outstanding immediately
prior to the issuance of such Additional Shares plus the number of shares of
Common Stock that the aggregate consideration for such Additional
<PAGE>   26
Shares would purchase at a consideration per share equal to such Conversion
Price and (II) the denominator of which shall be the number of shares of Common
Stock and Share Equivalents outstanding immediately prior to the issuance of
such Additional Shares plus the number of Additional Shares so issued. Such
adjustment for the Series D Preferred shall become effective immediately after
the issuance of such Additional Shares and the adjustment to the Series E
Conversion Price for such Additional Shares. No adjustment to the Series D
Conversion Price shall be made for the issuance of the Series E Preferred.  The
reissuance or resale of any Additional Shares or other Rights or Convertible
Securities shall also result in an adjustment to the Series D Conversion Price
to the extent an appropriate adjustment under Section 5(d)(xiii) has been made.

                          (ix)    It after the data of issuance of the Series E
Preferred the Corporation issues any Rights or Convertible Securities, and the
consideration per share for which Additional Shares may at any time thereafter
be issuable pursuant to such Rights or Convertible Securities (when added to
the consideration per share of Common Stock, if any, received for such Rights)
is less than the Series D Conversion Price, the Series D Conversion Price shall
be adjusted as provided in Section 5(d)(viii) an the basis that (A) the maximum
number of Additional Shares issuable pursuant to all such Rights or necessary
to effect the conversion or exchange of all such Convertible Securities shall
be deemed to have been issued and (B) the aggregate consideration (plus the
consideration, if any, received for such Rights) for such maximum number of
Additional Shares shall be deemed to be the consideration received and
receivable by the Corporation for the issuance of such Additional Shares
pursuant to such Rights or Convertible Securities.

         (x)     If after the date of issuance of the Series E Preferred the
Corporation issues Convertible Securities and the consideration per share for
which Additional Shares may at any time thereafter be issuable pursuant to such
Convertible Securities is less than the Series D Conversion Price, the Series D
Conversion Price shall be adjusted as provided in Section 5(d)(viii) on the
basis that (A) the maximum number of Additional Shares necessary to effect the
conversion or exchange of all such Convertible Securities shall be deemed to
have been issued and (B) the aggregate consideration for such maximum number of
Additional Shares shall be deemed to be the consideration received and
receivable by the Corporation
<PAGE>   27
for the issuance of such Additional Shares pursuant to such Convertible
Securities. No adjustment of the Series D Conversion Price shall be made under
this Section 5(d)(x) upon the issuance of any Convertible Securities issued
pursuant to the exercise of any Rights, to the extent that such adjustment was
previously made upon the issuance of such rights pursuant to Section 5(d)(ix).

                          (xi)    For purposes of Sections 5(d)(ix) and
5(d)(x), the relevant Series D Conversion Price shall be the Series D
Conversion Price in effect immediately prior to the earlier of (A) the record
date for the holders of Common Stock entitled to receive the Rights or
Convertible Securities and (B) the initial issuance of the Rights or
Convertible Securities and the adjustment provided for in either such section
shall became effective immediately after the earlier of the times specified in
clauses (A) and (B).

                         (xii)    No adjustment of the Series D Conversion
Price shall be made under Section 5(d)(viii) upon the issuance of any
Additional Shares pursuant to the exercise of any Rights or of any conversion
or exchange rights pursuant to any Convertible Securities, it such adjustment
was previously made in connection with the Issuance of such Rights or
Convertible securities (or in connection with the issuance of any Rights
therefor) pursuant to Section 5(d)(ix) or 5(d)(x).

                        (xiii)    If any Rights (or any portions, thereof) that
gave rise to an adjustment pursuant to Section 5(d)(ix) or any conversion or
exchange rights pursuant to any Convertible Securities that gave rise to an
adjustment pursuant to Section 5(d)(ix) or 5(d)(x) expire or terminate without
the exercise thereof and/or if by reason of the provisions or such Rights or
Convertible Securities there has been any increase, with the passage of time or
otherwise, in the consideration payable upon the exercise thereof, the Series D
Conversion Price shall be readjusted (but to no greater extent than originally
adjusted) on the basis of (A) eliminating from the computation Additional
Shares corresponding to such expired or terminated Rights or conversion or
exchange rights, (B) treating the Additional Shares, if any, actually issued or
issuable pursuant to the previous exercise  of such Rights or conversion or
exchange rights as having been issued for the consideration actually received
and receivable therefor and (C) treating any such Rights or conversion or
exchange rights that remain outstanding as being subject to
<PAGE>   28
exercise on the basis of the consideration payable upon the exercise or
conversion thereof as is in effect at such time; provided, however, that any
consideration actually received by the Corporation in connection with the
issuance of such Rights shall form part of the readjustment computation even
though such Rights expired without being exercised.  The Series D Conversion
Price shall be adjusted as provided in Section 5(d)(viii) and any applicable
provisions of Section 5(d)(ix) or 5(d)(x) as a result of any increase in the
number of Additional Shares issuable, or any decrease in the consideration
payable upon any issuance of Additional Shares, pursuant to any antidilution
provisions of any Rights or Convertible Securities.

                         (xiv)    (A)      If any Additional Shares,
Convertible Securities or Rights are issued for cash, the consideration
received therefor shall be deemed to be the amount of cash received.

                                  (B)      If any Additional Shares,
Convertible Securities or Rights are offered by the Corporation for
subscription, the consideration received therefor shall be deemed to be the
subscription price.

                                  (C)      If any Additional Shares,
Convertible Securities or Rights are sold to underwriters or dealers for public
offering without a subscription offering, the consideration received therefor
shall be deemed to be the public offering price.

                                  (D)      In any case covered by Section
5(d)(xiv) (A), (B) or (C), in determining the amount of any consideration
received by the Corporation in whole or in part other than in cash, the amount
of such consideration shall be deemed to be the fair market value of such
consideration as determined in good faith by the Board, and evidence of such
determination shall be filed with the minutes of the Corporation. If Additional
Shares are issued as part of a unit with Rights, the consideration received for
the Rights shall be deemed to be the portion of the consideration received for
such unit determined in good faith at the time of issuance by the Board, and
evidence of such determination shall be filed with the minutes of the
Corporation. If the Board does not make any such determination, the
consideration received for the Rights shall be deemed to be zero.  In either
event, the consideration received for the Additional Shares shall be deemed to
be
<PAGE>   29
the consideration received for such unit less the consideration deemed to have
been received for the Rights.

                                  (E)      In any case covered by Section
5(d)(xiv) (A), (B), (C) or (D), in determining the amount of consideration
received by the Corporation, (I) any amounts received or receivable for accrued
interest or accrued dividends shall be excluded and (II) any compensation,
underwriting commissions or concessions or expenses paid or incurred in
connection therewith shall not be deducted.

                                  (F)      In any case covered by section
5(d)(xiv) (A),(B), (C) or (D), there shall be added to the consideration
received by the Corporation at the time of issuance or sale (I) the minimum
aggregate amount of additional consideration payable to the Corporation upon
the exercise of Rights that relate to Convertible Securities and (II) the
minimum aggregate amount of consideration payable upon the conversion or
exchange thereof.

                                  (G)      If any Additional Shares,
Convertible Securities or Rights are issued in connection with any merger,
consolidation or other reorganization in which the Corporation is the surviving
corporation, the amount of consideration received therefor shall be deemed to
be the fair market value, as determined in good faith by the Board, of such
portion of the assets and business of the non-surviving person or persons as
the Board determines in good faith to be attributable to such Additional
Shares, Convertible Securities or Rights, and evidence of such determination
shall be filed with the minutes of the Corporation.

                          (xv)    If the Corporation effects any merger,
consolidation or other reorganization to which the Corporation is a party
(other than a merger or consolidation in which the Corporation is the surviving
corporation), any sale or conveyance to another person of all or substantially
all the assets of the Corporation or any statutory exchange of securities with
another person (including any exchange affected in connection with a merger of
a third person into the Corporation), the holder of each share of Series A
Preferred, Series D Preferred or Series E Preferred then outstanding shall have
the right thereafter to convert such share into the kind and amount of
consideration receivable pursuant to such transaction by a holder of the number
of shares of Common Stock into
<PAGE>   30
which such share of Series A Preferred, Series D Preferred or Series E
Preferred might have been converted immediately prior to such transaction,
assuming such holder of Common Stock failed to exercise its rights of
elections, if any, as to the kind or amount of consideration receivable upon
such transaction (provided that if the kind or amount of consideration
receivable pursuant to such transaction is not the same for each share of
Common Stock in respect of which such rights of election shall not have been
exercised ("non-electing share') then, for purposes of this Section 5(d)(xv),
the kind and amount of consideration receivable pursuant to such transaction
for each non-electing share shall be deemed to be the kind and amount so
receivable per share by a plurality of the non-electing shares).  Thereafter,
the holders or shares of Series A Preferred, Series D Preferred and Series E
Preferred shall be entitled to appropriate adjustments with respect to their
conversion rights to the end that the provisions set forth in this Section 5
shall correspondingly be made applicable, as nearly as may reasonably be, to
any consideration thereafter deliverable on conversion of shares of Series A
Preferred, Series D Preferred and Series E Preferred. Notwithstanding the
foregoing, this Section 5(d)(xv) shall not apply with regard to the Series E
Preferred to an event which is treated as a liquidation, dissolution or
winding-up of the Corporation with respect to such series pursuant to Section
3.

                         (xvi)    If a purchase, tender or exchange offer is
made to the holders of outstanding shares of Common Stock and, upon the
consummation of such offer, the person having made such offer (together with
its affiliates) beneficially owns 50% or more of the outstanding shares of
Common Stock, the Corporation shall not effect any merger, consolidation or
other reorganization with or sale, lease or other disposition of material
assets or issuance of securities to the person having made such offer or any
affiliate of such person, unless prior to the consummation thereof each holder
of shares of Series A Preferred, Series D Preferred and Series E Preferred
shall have been given a reasonable opportunity to elect to receive upon
conversion of the shares of Series A Preferred, Series D Preferred and Series E
Preferred then held by such holder (in lieu of the kind and amount of
consideration otherwise receivable upon conversion pursuant to the provisions
of this Section 5(d)), the consideration that would have been received pursuant
<PAGE>   31
to such offer by a holder of that number of shares of the Common Stock into
which one share of Series A Preferred, Series D Preferred or Series E Preferred
(as applicable) might then be converted if all such shares had been tendered
and accepted pursuant to such offer.

                        (xvii)    If the Corporation distributes generally to
holders of its outstanding shares of Common Stock or any other securities
entitled generally to participate in the earnings or assets of the Corporation
("Common Equity"), evidences of its debts, securities or other assets
(excluding any cash dividends and excluding any dividends or distributions
payable in Rights or Convertible Securities for which adjustment is otherwise
made pursuant to this Section 5(d)), the Series E Conversion Price shall be
adjusted by multiplying such Conversion Price in effect immediately prior to
the record date for such dividend or distribution by a fraction of which (X)
the numerator shall be the current market price per share of the Common Equity
(determined, if the Common Equity is not Common Stock, in the same way that the
current market price for Common Stock is determined) on such record date less
the then fair market value, as determined in good faith by the Board, of the
portion of the evidences of debt, securities or other assets so distributed or
applicable to the holder of one share of Common Equity and (Y) the denominator
shall be such current market price per share of the Common Equity, and evidence
of such determination shall be filed with the minutes of the Corporation. Such
adjustment shall become effective immediately after the record date for such
dividend or distribution but prior to any adjustment for such event to the
Series D Conversion Price pursuant to 5(d)(xviii).

                       (xviii)    If the Corporation distributes generally to
holders of its outstanding shares of Common Stock or any other Common Equity,
evidences of its debt, securities or other assets (excluding any cash dividends
and excluding any dividends or distributions payable in Rights or Convertible
Securities for which adjustment is otherwise made pursuant to this Section
5(d)), the Series D Conversion Price shall be adjusted by multiplying such
Conversion Price in effect immediately prior to the record date for such
dividend or distribution by a fraction of which (X) the numerator shall be the
current market price per share of the Common Equity (determined, if the Common
Equity
<PAGE>   32
is not Common Stock, in the same way that the current market price for Common
Stock is determined) on such record date less the then fair market value, as
determined in good faith by the Board, of the portion at the evidences or debt,
securities or other assets so distributed or applicable to the holder of one
share of Common Equity and (Y) the denominator shall be such current market
price per share of the Common Equity, and evidence or such determination shall
be filed with the minutes of the Corporation. Such adjustment shall became
effective immediately after the record date for such dividend or distribution
and immediately after the adjustment in Section 5(d)(xvii) has been made.

                         (xix)    If a state of facts not specifically
controlled by the provisions of this Section 5(d) occurs or is proposed that
would result in the conversion provisions of the Series A Preferred, Series D
Preferred and Series E Preferred not being fairly protected in accordance with
the essential intent and principles of such provisions, the Board shall make an
adjustment in the application of such provisions, in accordance with such
essential intent and principles so as to protect such conversion provisions,
and evidence of the Board's determination of such adjustment shall be filed
with the minutes of the Corporation.

                          (xx)    No adjustment in any Conversion Price shall
be required to be made unless it would require an increase or decrease of at
least one cent, but any adjustments not made because of this Section 5(d)(xx)
shall be carried forward and taken into account in any subsequent adjustment
otherwise required.  All calculations under this Section 5(d) shall be made to
the nearest cent or to the nearest 1/100th of a share, as the case may be. All
adjustments with respect to a transaction or event shall apply to subsequent
such transactions and events. Anything in this Section 5(d) to the contrary
notwithstanding, the Board shall be entitled (but shall not be obligated) to
make such irrevocable reduction in the Conversion Price, in addition to the
adjustments required by this Section 5(d), as in its discretion it shall
determine to be advisable in order to avoid or diminish any income deemed to be
received for Federal income tax purposes by any holder of shares of Common
Stock, Series A Preferred, Series D Preferred or Series E Preferred resulting
from any event or occurrence giving rise to an adjustment pursuant to this
<PAGE>   33
Section 5(d) or from any similar event or occurrence and evidence of the
Board's determination of such adjustment shall be filed with the minutes of the
Corporation.

                         (xxi)    Whenever any Conversion Price is adjusted
pursuant to this Section 5(d), (A) the Corporation shall promptly file with the
minutes of the Corporation a certificate of a firm of nationally recognized
independent public accountants or of the Corporation's chief accounting officer
setting forth such Conversion Price (and any change in the kind or amount of
consideration to be received by holders of shares of Series A Preferred, Series
D Preferred or Series E Preferred, as applicable, upon conversion) after such
adjustment and setting forth a brief statement of the facts requiring such
adjustment and the manner of computing the same and (B) a notice stating that
such Conversion Price has been adjusted, stating the effective date of such
adjustment and enclosing such certificate shall forthwith be mailed by the
Corporation to the holders of shares of Series A Preferred, Series D Preferred
or Series E Preferred, as applicable, at their addresses as shown on the stock
books of the Corporation.

                        (xxii)    If as a result of any adjustment pursuant to
this section 5(d), the holder of any share of Series A Preferred, Series D
Preferred or Series E Preferred surrendered for conversion becomes entitled to
receive any consideration other than Common Stock, (A) the Conversion Price
with respect to such other consideration shall be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to
the provisions with respect to Common Stock contained in this Section 5(d) and
(B) in the case such consideration shall consist of shares at Common Stock and
some other kind of consideration or of two or more kinds of consideration, the
Board shall determine in good faith the fair allocation of the adjusted
Conversion Price between or among such types of consideration, and evidence of
such determination shall be filed with the minutes of the Corporation.

                 (e)      Specified Events.  For purposes of this Section 5(e),
a "Specified Event" shall occur if (i) the Corporation takes any action that
would require any adjustment in the Conversion Price pursuant to Section
5(d)(xvii) or 5(d)(xviii), (ii) the Corporation authorizes the granting to the
holders of the Common Stock of any Rights or of any other rights, (iii) there
is any capital stock reorganization or reclassification of
<PAGE>   34
the Common Stock (other than a subdivision or combination of the outstanding
Common Stock and other than a change in the par value of the Common Stock), or
any merger, consolidation or other reorganization to which the Corporation is a
party, or any statutory exchange of securities with another person and for
which approval of any stockholders of the Corporation is required, or any sale
or transfer of all or substantially all the assets of the Corporation or (iv)
there is a voluntary liquidation, dissolution or winding up of the Corporation.
If a Specified Event occurs, the Corporation shall cause to be filed with the
minutes of the Corporation, and shall cause to be mailed to the holders of
shares of the Series A Preferred, Series D Preferred and Series E Preferred at
their addresses as shown on the stock books of the Corporation, at least 10
days prior to the applicable data specified below, a notice stating (A) the
date on which a record is to be taken for the purpose of any distribution or
Rights relating to such Specified Event or, if a record is not to be taken, the
date as of which the holders of Common Stock of record to be entitled to such
distribution or Rights are to be determined, or (B) the date on which the
reorganization, reclassification, consolidation, merger, statutory exchange,
sale, transfer, dissolution, liquidation or winding-up relating to such
Specified Event is expected to become effective, and the date as of which it is
expected that holders of Common Stock of record shall be entitled to exchange
their shares at Common Stock for securities or other property deliverable upon
such Specified Event.

         (f)     Reservation of Common Stock.  The Corporation shall at all
times reserve and keep available, free from preemptive and subscription rights,
out of its authorized but unissued shares of Common Stock, for the purpose of
effecting conversions of the Series A Preferred, Series D Preferred and Series
E Preferred, the full number of shares of Common Stock deliverable upon the
conversion of all outstanding shares of Series A Preferred, Series D Preferred
and Series E Preferred not theretofore converted. For this purpose, the number
of shares of Common Stock deliverable upon the conversion of all outstanding
shares of Series A Preferred, Series D Preferred and Series E Preferred shall
be computed as if at the time of computation all such outstanding shares were
held by a single holder.

                 (g)      Listing. With respect to any securities required to
be delivered upon conversion of the Series A Preferred, Series D Preferred and
Series E Preferred, the
<PAGE>   35
Corporation shall use its best efforts to list such securities prior to such
delivery upon each securities exchange, it any, on which any securities of such
class are already listed.

                 (h)      Taxes. The Corporation shall pay all documentary
stamp or similar issue or transfer taxes payable in respect of the issue or
delivery of securities on conversion of the Series A Preferred, Series D
Preferred and Series E Preferred; provided, however, that

                           (i)    the Corporation shall not be required to pay
any tax payable in respect of any transfer involved in the issue or delivery of
securities in a name other than that of the holder of the shares of Series A
Preferred, Series D Preferred and Series E Preferred to be converted and (ii)
no such issue or delivery shall be made unless and until such holder has paid
to the Corporation the amount of any such tax or has established, to the
satisfaction of the Corporation, that such tax has been paid or provided for.

         Section 6. Status of Shares.  Upon any conversion or any redemption,
repurchase or other acquisition by the Corporation of shares of Series A
Preferred, Series D Preferred or Series E Preferred, the shares of Series A
Preferred, Series D Preferred or Series E Preferred so converted, redeemed,
repurchased or acquired shall be retired and cancelled and shall not be
available for reissuance.

         Section 7. Definitions and Construction.  As used in this Article
Fourth, (a) "herein", "hereof", "hereunder" and other like words mean or refer
to this Article Fourth; (b) "outstanding", when used with reference to shares

         FURTHER RESOLVED, that a new Article shall be added to the
Corporation's Certificate of Incorporation, as follows:



         THIRTEENTH: In anticipation that International Business Machines
Corporation ("IBM") will be a substantial stockholder of the Corporation, and
in anticipation that the Corporation and such stockholder may engage in the
same or similar activities or lines of business and have an interest in the
same area of corporate opportunities, and in recognition of the benefits to be
derived by the Corporation through its continued contractual, corporate and
business relations with such stockholder, the provisions of this Article
Thirteenth are set forth to regulate and define the conduct of certain affairs
of the Corporation as they may involve such stockholder and its officers and
employees, and the powers, rights, duties and liabilities of the Corporation
and its officers, directors and stockholders in connection therewith.

directors of the Corporation.

         SECTION 2. Corporate Opportunities.  In the event that IBM or any
officer, director, employee or former employee of IBM acquires knowledge of a
potential transaction or matter which may be a corporate opportunity for both
IBM and the Corporation, neither IBM nor its officers, directors, employees or
former employees shall have any duty to communicate or offer such corporate
opportunity to the Corporation and neither IBM nor its officers directors,
employees or former employees shall be liable to the Corporation or its
stockholders for breach of any fiduciary or other duty, as a stockholder or
otherwise, by reason of the fact that IBM pursues or acquires such corporate
opportunity for itself, directs such corporate opportunity to another person or
entity, or does not communicate such corporate opportunity or information
regarding such corporate opportunity to the Corporation.

         SECTION 3. Scope of Article. The provisions of this Article Thirteenth
shall be effective to the maximum extent permitted by law.

         FURTHER RESOLVED, that a new Article shall be added to the
Corporation's Certificate of Incorporation, as follows:

         FOURTEENTH:      The following matters, which relate to actions that
can only be taken by the Corporation with the approval of the Board of
Directors, shall be authorized only as follows:

         SECTION 1.  Matters Requiring Board Approval by Simple Majority
Director Vote.  The following matters shall require a Simple Majority Director
Vote:

                 (a)      the incurring by the Corporation or any subsidiary of

months from the date such debt or other borrowing was incurred by the

         SECTION 2.  Matters Requiring Board Approval by Supermajority Director

                 (d)      a corporate reorganization, or the merger or
consolidation of the Corporation with or into any other corporation or
corporations, which would result in the holders of Voting Securities

Power of the resulting or surviving corporation immediately thereafter (a
"Significant Merger"), or any liquidation or dissolution of the Corporation;

                 (e)      changes in accounting methods or policies and any
change in the Corporation's auditors; or

                 (f)      any amendment to the Certificate of Incorporation or

affirmative approval of each of the holders at a majority of the shares of each
of the (i) Common Stock, (ii) Series A Preferred and Series D Preferred voting
together as a group, and (iii) Series E Preferred, the Corporation will not (i)
consummate a Significant Merger or
<PAGE>   39
(ii) sell all or substantially all of the Corporation's assets.  Unless
pursuant to a vote by each of the holders of a majority of the shares of each
of the (i) Common Stock, (ii) Series A Preferred and the Series D Preferred

Corporation at any meeting of shareholders of the Corporation if all Voting
Securities (assuming full conversion, exchange or exercise of all securities,

in the election of directors of the Corporation were present and voted at such
meeting, other than votes that may be cast only by one class or series of
shares (other than Common Stock) or upon the happening of a contingency.  For
the purpose of the application of this definition, any prohibition or
restriction on voting any shares of stock as a result of any shareholders
agreement shall not be given effect.

                 (d)      "Voting Securities" means the shares of Common Stock
and any other securities of the Corporation entitled to vote generally in the

                            CERTIFICATE OF AMENDMENT

                                     OF THE

                          CERTIFICATE OF INCORPORATION

                                       OF

                                SYNON CORPORATION

         Richard H. Goldberg and Paul K. Wilde each hereby certifies that:

         (1) They are the President and Secretary, respectively, of Synon
Corporation, a Delaware corporation (the "Corporation").

         (2) The first three paragraphs of Article FOURTH of the Certificate of
Incorporation of this Corporation are hereby amended to read in their entirety
as follows:

                  "The Corporation is authorized to issue two classes of capital
         stock to be designated respectively "Common Stock" and "Preferred
         Stock." The total number of shares of all classes of stock which the
         Corporation shall have the authority to issue is 62,972,686 shares.
         The total number of shares of Common Stock that the Corporation shall
         have authority to issue is 50,000,000 shares, $0.001 par value per
         share. The total number of shares of Preferred Stock that the
         Corporation shall have authority to issue is 12,972,686 shares,
         $0.001 par value per share, of which: (i) 2,687,750 shall be designated
         Series A Preferred Stock ("Series A Preferred"), (ii) 3,618,269 shall
         be designated Series D Preferred Stock ("Series D Preferred"), (iii)
         l,666,667 shall be designated Series E Preferred Stock ("Series E
         Preferred"), and (iv) 5,000,000 of which shall be undesignated as to
         series. Upon the filing of this Certificate of Amendment, each two (2)
         issued and outstanding shares of Common Stock of this corporation shall
         be exchanged for and converted into one (1) share of Common Stock,
         including proportionate adjustments to the conversion prices of the
         outstanding Preferred Stock.

                  The Preferred Stock may be issued from time to time in one or
         more series. The Board of Directors is hereby authorized, subject to
         limitations prescribed by law, to fix by resolution or resolutions the
         designations, powers, preferences and rights, and the qualifications,
         limitations or restrictions thereof, of any wholly unissued series of
         Preferred Stock, including without limitation authority to fix by
         resolution or resolutions the dividend rights, dividend rate,
         conversion rights, voting rights, rights and terms of redemption
         (including sinking fund provisions), redemption price or prices, and
         liquidation preferences of any such series, and the number of shares
         constituting any such series and the designation

                                       -1-


<PAGE>   2
         thereof, or any of the foregoing. Prior to the Company's Initial Public
         Offering (as defined below), no such series or alteration may be
         authorized which (i) impairs any right, privilege, preference or term
         accorded any existing series of Preferred Stock, (ii) grants any
         liquidation preference on parity with or superior to the Series E
         Preferred Stock, (iii) initially authorizes any series with voting
         rights or dividend preferences greater than that accorded one share of
         Common Stock or otherwise provides for disproportionate voting
         privileges, (iv) authorizes the redemption of such series or is entered
         into with any contract requiring the repurchase of such series (or part
         thereof) or (v) is initially convertible into more than one share of
         Common Stock or otherwise provides for disproportionate conversion
         privileges.

                  The Board of Directors is further authorized to increase (but
         not above the total number of authorized shares of the class) or
         decrease (but not below the number of shares of any such series then
         outstanding) the number of shares of any series, the number of which
         was fixed by it, subsequent to the issuance of shares of such series
         then outstanding, subject to the powers, preferences and rights, and
         the qualifications, limitations and restrictions thereof stated in the
         Certificate of Incorporation or the resolution of the Board of
         Directors originally fixing the number of shares of such series. If the
         number of shares of any series is so decreased, then the shares
         constituting such decrease shall resume the status which they had prior
         to the adoption of the resolution originally fixing the number of
         shares of such series."

         (2) Section 3(b) of Article FOURTH of the Certificate of Incorporation
of this Corporation is hereby amended to read in its entirety as follows:

                  "(b) After payment of the full amount of the Liquidation
         Preference for the Series E Preferred has been made to the holders of
         such shares, the holders of shares of Series D Preferred shall be
         entitled to receive out of the assets of the Corporation available for
         distribution to its stockholders, whether from capital, surplus or
         earnings, before any distribution is made to holders of Common Stock or
         any other series of Preferred Stock or other class or series of capital
         stock, an amount per share of Series D Preferred equal to $3.35 for
         each outstanding share of Series D Preferred (the "Original Series D
         Issue Price") plus an amount equal to all declared and unpaid dividends
         (such sum being referred to as the "Liquidation Preference" for the
         Series D Preferred). In the event the assets of the Corporation are
         insufficient to pay such Liquidation Preference in full, the assets
         shall be distributed pro rata among the holders of the Series D
         Preferred based on the number of shares of stock owned by each holder."

this Corporation is hereby amended to read in its entirety as follows:

                                       OF

                                SYNON CORPORATION

PURSUANT TO SECTION 245 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

         Richard H. Goldberg and Paul K. Wilde each hereby certifies that:

         (1) They are the President and Secretary, respectively, of Synon
Corporation, a Delaware corporation.

         (2) The Certificate of Incorporation of this Corporation, originally
filed with the Secretary of State of the State of Delaware on May 11, 1990, is
hereby amended and restated in its entirety to read as follows:

         "FIRST. The name of the corporation is Synon Corporation (the
"Corporation").

         SECOND. The address of the Corporation's registered office in the State
of Delaware is Corporation Trust Center, 1209 Orange Street, in the City of
Wilmington, County of New Castle, Delaware 19901. The name of its registered
agent at such address is the Corporation Trust Company.

         THIRD. The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of Delaware.

         FOURTH. The Corporation is authorized to issue two classes of capital
stock to be designated respectively "Common Stock" and "Preferred Stock." The
total number of shares of all classes of stock which the Corporation shall have
the authority to issue is Fifty-Five Million (55,000,000) shares. The total
number of shares of Common Stock that the Corporation shall have authority to
issue is Fifty Million (50,000,000) shares, $0.001 par value per share. The
total number of shares of Preferred Stock that the Corporation shall have
authority to issue is Five Million (5,000,000) shares, $0.001 par value per
share.

         The Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, subject to limitations
prescribed by law, to fix by resolution or resolutions the designations, powers,
preferences and rights, and the qualifications, limitations or restrictions
thereof, of any wholly unissued series of Preferred Stock, including without
limitation authority to fix by resolution or resolutions the dividend rights,
dividend rate, conversion rights,


<PAGE>   2
voting rights, rights and terms of redemption (including sinking fund
provisions), redemption price or prices, and liquidation preferences of any such
series, and the number of shares constituting any such series and the
designation thereof, or any of the foregoing.

         The Board of Directors is further authorized to increase (but not above
the total number of authorized shares of the class) or decrease (but not below
the number of shares of any such series then outstanding) the number of shares
of any series, the number of which was fixed by it, subsequent to the issuance
of shares of such series then outstanding, subject to the powers, preferences
and rights, and the qualifications, limitations and restrictions thereof stated
in the Certificate of Incorporation or the resolution of the Board of Directors
originally fixing the number of shares of such series. If the number of shares
of any series is so decreased, then the shares constituting such decrease shall
resume the status which they had prior to the adoption of the resolution
originally fixing the number of shares of such series.

         FIFTH.    The Corporation is to have perpetual existence.

         SIXTH. Elections of directors need not be by written ballot unless a
stockholder demands election by written ballot at the meeting and before voting
begins or unless the Bylaws of the Corporation shall so provide.

         SEVENTH. The number of directors which constitute the whole Board of
Directors of the Corporation shall be designated in the Bylaws of the
Corporation.

         EIGHTH. In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors of the Corporation is expressly authorized to
make, alter, amend or repeal the Bylaws of the Corporation.

         NINTH. To the fullest extent permitted by the Delaware General
Corporation Law as the same exists or may hereafter be amended, no director of
the Corporation shall be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director.

         Neither any amendment nor repeal of this Article, nor the adoption of
any provision of this Certificate of Incorporation inconsistent with this
Article, shall eliminate or reduce the effect of this Article in respect of any
matter occurring, or any cause of action, suit or claim that, but for this
Article, would accrue or arise, prior to such amendment, repeal or adoption of
an inconsistent provision.

         TENTH. Meetings of stockholders may be held within or without the State
of Delaware, as the Bylaws may provide. The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the Bylaws of the Corporation.



<PAGE>   3
         ELEVENTH. No action shall be taken by the stockholders of the
Corporation except at an annual or special meeting of the stockholders called in
accordance with the Bylaws and no action shall be taken by the stockholders by
written consent.

         TWELFTH. At the election of directors of the Corporation, each holder
of stock of any class or series shall be entitled to one vote for each share
held. No stockholder will be permitted to cumulate votes at any election of
directors.

         THIRTEENTH. The Corporation reserves the right to amend, alter, change
or repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation."

         (3) The foregoing Amended and Restated Certificate of Incorporation has
been duly adopted by the Board of Directors of this Corporation in accordance
with Section 245 of the General Corporation Law of the State of Delaware.

         (4) The foregoing Amended and Restated Certificate of Incorporation
only restates and integrates and does not further amend the provisions of this
Corporation's Certificate of Incorporation as heretofore amended or
supplemented, and there is no discrepancy between the provisions of this
Corporation's Certificate of Amendment as heretofore amended or supplemented and
the provisions of the foregoing Amended and Restated Certificate of
Incorporation.

         All notices of meetings of stockholders shall be sent or otherwise

more than sixty (60) days before the date of the meeting. The notice shall

of the annual meeting, those matters which the board of directors, at the time

brought before the meeting by a stockholder. For such nominations or other
business to be considered properly brought before the meeting by a stockholder,

to bring such business before such meeting. To be timely, such stockholder's
notice must be delivered to or mailed and received by the secretary of the
Corporation not less than 90 days prior to the meeting; provided, however, that
in the case of a meeting called by or on behalf of the Board of Directors of the
Corporation where prior notice, or public disclosure, of the meeting has not

stockholder to be timely must be so received not later than the close of
business on the tenth day following the day on which such notice of the date of
the meeting was mailed or such public disclosure was made. To be in proper form,
a stockholder's notice to the secretary shall set forth:

               the nature of the business to be proposed;

               (ii) a representation that the stockholder is a holder of record
               of stock of the Corporation entitled to vote at such meeting and,
               if applicable, intends to appear in person or by proxy at the
               meeting to nominate the person or persons specified in the notice
               or introduce the business specified in the notice;

               (iii) if applicable, a description of all arrangements or
               understandings between the stockholder and each nominee and any
               other person or persons (naming such person or persons) pursuant
               to which the nomination or nominations are to be made by the
               stockholder;

               (iv) such other information regarding each nominee or each matter
               of business to be proposed by such stockholder as would be
               required to be included in a proxy statement filed pursuant to
               the proxy rules of the Securities and Exchange Commission had the
               nominee been nominated, or intended to be nominated, or the
               matter been proposed, or intended to be proposed by the board of
               directors' and

               (v) if applicable, the consent of each nominee to serve as
               director of the Corporation if so elected.

         The chairman of the meeting may refuse to acknowledge the nomination of
any person or the proposal of any business not made in compliance with the
foregoing procedure.

         2.6      MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

         Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication. Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the stockholder at the address of that stockholder
appearing on the books of the corporation or given by the stockholder to the
corporation for the purpose of notice. Notice shall be deemed to have been given
at the time when delivered personally or deposited in the mail or sent by
telegram or other means of written communication.




                                       3
<PAGE>   8

         An affidavit of the mailing or other means of giving any notice of any
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

         2.7      QUORUM

         The holders of a majority in voting power of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
certificate of incorporation. If, however, such quorum is not present or
represented at any meeting of the stockholders, then either (i) the chairman of
the meeting or (ii) the stockholders entitled to vote thereat, present in person
or represented by proxy, shall have power to adjourn the meeting in accordance
with Section 2.7 of these bylaws.

         When a quorum is present at any meeting, the vote of the holders of a
majority of the stock having voting power present in person or represented by
proxy shall decide any question brought before such meeting, unless the question
is one upon which, by express provision of the laws of the State of Delaware or
of the certificate of incorporation or these bylaws, a different vote is
required, in which case such express provision shall govern and control the
decision of the question.

         If a quorum be initially present, the stockholders may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

         2.8      ADJOURNED MEETING; NOTICE

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

         2.9      VOTING

         The stockholders entitled to vote at any meeting of stockholders shall
be determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint
owners, and to voting trusts and other voting agreements).

         2.10     STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

         Unless otherwise provided in the certificate of incorporation, any
action required by this chapter to be taken at any annual or special meeting of
stockholders of a corporation, or any action that may be taken at any annual or
special meeting of such stockholders, may be taken without a meeting, without
prior notice, and without a vote if a consent in writing, setting forth the
action so taken, is signed by the holders of outstanding stock having not less
than the minimum number of votes that would be necessary to authorize or take
such action at a meeting at which all shares entitled to vote thereon were
present and voted.

         Prompt notice of the taking of the corporate action without a meeting
by less than unanimous written consent shall be given to those stockholders who
have not consented in writing. If the action which is consented to is such as
would have required the filing of a certificate under any section of the General
Corporation Law of Delaware if such action had been voted on by stockholders at
a meeting thereof, then the certificate filed under such section shall state, in
lieu of any statement required by such section concerning any vote of
stockholders, that written notice and written consent have been given as
provided in Section 228 of the General Corporation Law of Delaware.

         Notwithstanding the foregoing, no such action by written consent may be
taken following the earlier to occur of the closing of a firm commitment
underwritten public offering registered under the Securities Act of 1933, as
amended, or such time as the corporation is required to file reports pursuant to
Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended.

         2.11     RECORD DATE FOR STOCKHOLDER NOTICE; VOTING

         For purposes of determining the stockholders entitled to notice of any
meeting or to vote thereat, the board of directors may fix, in advance, a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted by the board of directors and which shall not be more
than sixty (60) days nor less than ten (10) days before the date of any such
meeting, and in such event only stockholders of record on the date so fixed are
entitled to notice and to vote, notwithstanding any transfer of any shares on
the books of the corporation after the record date.

         If the board of directors does not so fix a record date, the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the business day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the business day next preceding the day on which the
meeting is held.

                                       6
<PAGE>   11

         A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting
unless the board of directors fixes a new record date for the adjourned meeting,
but the board of directors shall fix a new record date if the meeting is
adjourned for more than thirty (30) days from the date set for the original
meeting.

         The record date for any other purpose shall be as provided in Section
8.1 of these bylaws.

         2.12     PROXIES

         Every person entitled to vote for directors, or on any other matter,
shall have the right to do so either in person or by one or more agents
authorized by a written proxy signed by the person and filed with the secretary
of the corporation, but no such proxy shall be voted or acted upon after three
(3) years from its date, unless the proxy provides for a longer period. A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission, telefacsimile or
otherwise) by the stockholder or the stockholder's attorney-in-fact. The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Section 212(e) of the General Corporation Law of
Delaware.

         2.13     ORGANIZATION

         The president, or in the absence of the president, the chairman of the
board, shall call the meeting of the stockholders to order, and shall act as
chairman of the meeting. In the absence of the president, the chairman of the
board, and all of the vice presidents, the stockholders shall appoint a chairman
for such meeting. The chairman of any meeting of stockholders shall determine
the order of business and the procedures at the meeting, including such matters
as the regulation of the manner of voting and the conduct of business. The
secretary of the corporation shall act as secretary of all meetings of the
stockholders, but in the absence of the secretary at any meeting of the
stockholders, the chairman of the meeting may appoint any person to act as
secretary of the meeting.

         2.14     LIST OF STOCKHOLDERS ENTITLED TO VOTE

         The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall 

                                       7
<PAGE>   12

also be produced and kept at the time and place of the meeting during the whole
time thereof, and may be inspected by any stockholder who is present.


                                   ARTICLE III

                                    DIRECTORS

         3.1      POWERS

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

         3.2      NUMBER OF DIRECTORS

         The board of directors shall consist of six (6) members. The number
of directors may be changed by an amendment to this bylaw, duly adopted by the
board of directors or by the stockholders, or by a duly adopted amendment to the
certificate of incorporation.

         3.3      ELECTION AND TERM OF OFFICE OF DIRECTORS

         Except as provided in Section 3.4 of these bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Each director, including a director elected or appointed to fill
a vacancy, shall hold office until the expiration of the term for which elected
and until a successor has been elected and qualified.

         3.4      RESIGNATION AND VACANCIES

         Any director may resign effective on giving written notice to the
chairman of the board, the president, the secretary or the board of directors,
unless the notice specifies a later time for that resignation to become
effective. If the resignation of a director is effective at a future time, the
board of directors may elect a successor to take office when the resignation
becomes effective.

         Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote of
the stockholders or by court order may be filled only by the affirmative vote of
a majority of the shares represented and voting at a duly held meeting at which
a quorum is present (which shares voting affirmatively also constitute a
majority of the required

                                       8
<PAGE>   13
quorum). Each director so elected shall hold office until the next annual
meeting of the stockholders and until a successor has been elected and
qualified.

         Unless otherwise provided in the certificate of incorporation or these
bylaws:

                  (i) Vacancies and newly created directorships resulting from
any increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

                  (ii) Whenever the holders of any class or classes of stock or
series thereof are entitled to elect one or more directors by the provisions of
the certificate of incorporation, vacancies and newly created directorships of
such class or classes or series may be filled by a majority of the directors
elected by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

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

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

         3.5      REMOVAL OF DIRECTORS

         Unless otherwise restricted by statute, by the certificate of
incorporation or by these bylaws, any director or the entire board of directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors.

         3.6      PLACE OF MEETINGS; MEETINGS BY TELEPHONE

                                       9
<PAGE>   14

         Regular meetings of the board of directors may be held at any place
within or outside the State of Delaware that has been designated from time to
time by resolution of the board. In the absence of such a designation, regular
meetings shall be held at the principal executive office of the corporation.
Special meetings of the board may be held at any place within or outside the
State of Delaware that has been designated in the notice of the meeting or, if
not stated in the notice or if there is no notice, at the principal executive
office of the corporation.

         Any meeting of the board, regular or special, may be held by conference
telephone or similar communication equipment, so long as all directors
participating in the meeting can hear one another; and all such participating
directors shall be deemed to be present in person at the meeting.

         3.7      FIRST MEETINGS

         The first meeting of each newly elected board of directors shall be
held at such time and place as shall be fixed by the vote of the stockholders at
the annual meeting. In the event of the failure of the stockholders to fix the
time or place of such first meeting of the newly elected board of directors, or
in the event such meeting is not held at the time and place so fixed by the
stockholders, the meeting may be held at such time and place as shall be
specified in a notice given as hereinafter provided for special meetings of the
board of directors, or as shall be specified in a written waiver signed by all
of the directors.

         3.8      REGULAR MEETINGS

         Regular meetings of the board of directors may be held without notice
at such time as shall from time to time be determined by the board of directors.
If any regular meeting day shall fall on a legal holiday, then the meeting shall
be held at the same time and place on the next succeeding full business day.

         3.9      SPECIAL MEETINGS; NOTICE

         Special meetings of the board of directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two directors.

         Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail,
telecopy or telegram, charges prepaid, addressed to each director at that
director's address as it is shown on the records of the corporation. If the
notice is mailed, it shall be deposited in the United States mail at least four
(4) days before the time of the holding of the meeting. If the notice is
delivered personally or by telephone, telecopy or telegram, it shall be

forty-eight (48) hours before the time of the holding of the meeting.

<PAGE>   15

Any oral notice given personally or by telephone may be communicated either to
the director or to a person at the office of the director who the person giving
the notice has reason to believe will promptly communicate it to the director.
The notice need not specify the purpose or the place of the meeting, if the
meeting is to be held at the principal executive office of the corporation.

         3.10     QUORUM

A majority of the authorized number of directors shall constitute a quorum for
the transaction of business, except to adjourn as provided in Section 3.12 of
these bylaws. Every act or decision done or made by a majority of the directors
present at a duly held meeting at which a quorum is present shall be regarded as
the act of the board of directors, subject to the provisions of the certificate
of incorporation and applicable law.

         A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the quorum for that meeting.

         3.11     WAIVER OF NOTICE

         Notice of a meeting need not be given to any director (i) who signs a
waiver of notice, whether before or after the meeting, or (ii) who attends the
meeting other than for the express purposed of objecting at the beginning of the
meeting to the transaction of any business because the meeting is not lawfully
called or convened. All such waivers shall be filed with the corporate records
or made part of the minutes of the meeting. A waiver of notice need not specify
the purpose of any regular or special meeting of the board of directors.

                                       11
<PAGE>   16
         3.12     ADJOURNMENT

of the adjournment.

         3.14     BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

         Any action required or permitted to be taken by the board of directors
may be taken without a meeting, provided that all members of the board
individually or collectively consent in writing to that action. Such action by
written consent shall have the same force and effect as a unanimous vote of the
board of directors. Such written consent and any counterparts thereof shall be
filed with the minutes of the proceedings of the board of directors.

         3.15     FEES AND COMPENSATION OF DIRECTORS

         Directors and members of committees may receive such compensation, if
any, for their services and such reimbursement of expenses as may be fixed or

capacity as an officer, agent, employee or otherwise and receiving compensation
for those services.

         3.16     APPROVAL OF LOANS TO OFFICERS

         The corporation may lend money to, or guarantee any obligation of, or

corporation or any of its subsidiaries, whenever, in the judgment of the
directors, such loan, guaranty or assistance may reasonably be expected to
benefit the corporation. The loan, guaranty or other assistance may be with or
without interest and may be unsecured, or secured in such manner as the board of
directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation. Nothing contained in this section shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

                                   COMMITTEES

          4.1    COMMITTEES OF DIRECTORS

         The board of directors may, by resolution adopted by a majority of the
authorized number of directors, designate one (1) or more committees, each
consisting of one (1) or more directors, to serve at the pleasure of the board.
The board may designate one (1) or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of
the committee. The appointment of members or alternate members of a committee
requires the vote of a majority of the authorized number of directors. Any
committee, to the extent provided in the resolution of the board, shall have and
may exercise all the powers and authority of the board, but no such committee
shall have the power or authority to (i) amend the certificate of incorporation
(except that a committee may, to the extent authorized in the resolution or
resolutions providing for the issuance of shares of stock adopted by the board
of directors as provided in Section 151(a) of the General Corporation Law of
Delaware, fix the designations and any of the preferences or rights of such
shares relating to dividends, redemption, dissolution, any distribution of
assets of the corporation or the conversion into, or the exchange of such shares
for, shares of any other class or classes or any other series of the same or any
other class or classes of stock of the corporation), (ii) adopt an agreement of
merger or consolidation under Sections 251 or 252 of the General Corporation Law
of Delaware, (iii) recommend to the stockholders the sale, lease or exchange of
all or substantially all of the corporation's property and assets, (iv)
recommend to the stockholders a dissolution of the corporation or a revocation
of a dissolution or (v) amend the bylaws of the corporation; and, unless the
board resolution establishing the committee, the bylaws or the certificate of
incorporation expressly so provide, no such committee shall have the power or
authority to declare a dividend, to authorize the issuance of stock, or to adopt
a certificate of ownership and merger pursuant to Section 253 of the General
Corporation Law of Delaware.

         4.2      MEETINGS AND ACTION OF COMMITTEES

3.13 (notice of adjournment) and Section 3.14 (board action by written consent
without meeting), with such changes in the context of those bylaws as are
necessary to substitute the committee and its members for the board of directors
and its members; provided, however, that the time of regular meetings of
committees may be determined either by resolution of the board of directors or
by resolution of the committee, that special meetings of committees may also be
called



                                       13
<PAGE>   18

by resolution of the board of directors, and that notice of special
meetings of committees shall also be given to all alternate members, who shall

provisions of these bylaws.

         4.3      COMMITTEE MINUTES

directors, by any Corporate Officer upon whom such power of removal may be
conferred by the board of directors.

to the corporation. Any resignation shall take effect at the date of the receipt

                INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES
                                AND OTHER AGENTS

         6.1      INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The corporation shall, to the maximum extent and in the manner
permitted by the General Corporation Law of Delaware as the same now exists or
may hereafter be amended, indemnify any person against expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlement actually and
reasonably incurred in connection with any threatened, pending or completed
action, suit, or proceeding in which such person was or is a party or is
threatened to be made a party by reason of the fact that such person is or was a
director or officer of the corporation. For purposes of this Section 6.1, a
"director" or "officer" of the corporation shall mean any person (i) who is or
was a director or officer of the corporation, (ii) who is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was a
director or officer of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

         The corporation shall be required to indemnify a director or officer in
connection with an action, suit, or proceeding (or part thereof) initiated by
such director or officer only if the initiation of such action, suit, or
proceeding (or part thereof) by the director or officer was authorized by the
Board of Directors of the corporation.

         The corporation shall pay the expenses (including attorney's fees)
incurred by a director or officer of the corporation entitled to indemnification
hereunder in defending any action, suit or proceeding referred to in this
Section 6.1 in advance of its final disposition; provided, however, that payment
of expenses incurred by a director or officer of the corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an undertaking by the director or officer to repay all amounts
advanced if it should ultimately be determined that the director or officer is
not entitled to be indemnified under this Section 6.1 or otherwise.

         The rights conferred on any person by this Article shall not be
exclusive of any other rights which such person may have or hereafter acquire
under any statute, provision of the corporation's Certificate of Incorporation,
these bylaws, agreement, vote of the stockholders or disinterested directors or
otherwise.



                                       19
<PAGE>   24

         Any repeal or modification of the foregoing provisions of this Article
shall not adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the time of such repeal or
modification.

         6.2      INDEMNIFICATION OF OTHERS

         The corporation shall have the power, to the maximum extent and in the
manner permitted by the General Corporation Law of Delaware as the same now
exists or may hereafter be amended, to indemnify any person (other than
directors and officers) against expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred in
connection with any threatened, pending or completed action, suit, or
proceeding, in which such person was or is a party or is threatened to be made a
party by reason of the fact that such person is or was an employee or agent of
the corporation. For purposes of this Section 6.2, an "employee" or "agent" of
the corporation (other than a director or officer) shall mean any person (i) who
is or was an employee or agent of the corporation, (ii) who is or was serving at
the request of the corporation as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was an
employee or agent of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

         6.3      INSURANCE

         The corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the corporation,
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,
whether or not the corporation would have the power to indemnify him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

                                   ARTICLE VII

                               RECORDS AND REPORTS

         7.1      MAINTENANCE AND INSPECTION OF RECORDS

         The corporation shall, either at its principal executive office or at
such place or places as designated by the board of directors, keep a record of
its stockholders listing their names and addresses and the number and class of

accounting books and other records of its business and properties.

                                       20
<PAGE>   25

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

         7.2      INSPECTION BY DIRECTORS

         Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders and its other books and records for a purpose
reasonably related to his or her position as a director.

         7.3      ANNUAL STATEMENT TO STOCKHOLDERS

         The board of directors shall present at each annual meeting, and at any
special meeting of the stockholders when called for by vote of the stockholders,
a full and clear statement of the business and condition of the corporation.

         7.4      REPRESENTATION OF SHARES OF OTHER CORPORATIONS

         The chairman of the board, if any, the president, any vice president,
the chief financial officer, the secretary or any assistant secretary of this
corporation, or any other person authorized by the board of directors or the
president or a vice president, is authorized to vote, represent and exercise on
behalf of this corporation all rights incident to any and all shares of the
stock of any other corporation or corporations standing in the name of this
corporation. The authority herein granted may be exercised either by such person
directly or by any other person authorized to do so by proxy or power of
attorney duly executed by such person having the authority.

         7.5      CERTIFICATION AND INSPECTION OF BYLAWS

         The original or a copy of these bylaws, as amended or otherwise altered
to date, certified by the secretary, shall be kept at the corporation's
principal executive office and shall be open to inspection by the stockholders
of the corporation, at all reasonable times during office hours.

                                  ARTICLE VIII

                                 GENERAL MATTERS

         8.1      RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

         For purposes of determining the stockholders entitled to receive
payment of any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the board of directors may fix, in advance, a record date, which shall not
precede the date upon which the resolution fixing the record date is adopted and
which shall not be more than sixty (60) days before any such action. In that
case, only stockholders of record at the close of business on the date so fixed
are entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided by law.

         If the board of directors does not so fix a record date, then the
record date for determining stockholders for any such purpose shall be at the
close of business on the day on which the board of directors adopts the
applicable resolution.

         8.2      CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

         From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

         8.3      CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED

         The board of directors, except as otherwise provided in these bylaws,
may authorize and empower any officer or officers, or agent or agents, to enter
into any contract or execute any instrument in the name of and on behalf of the
corporation; such power and authority may be general or confined to specific
instances. Unless so authorized or ratified by the board of directors or within
the agency power of an officer, no officer, agent or employee shall have any
power or authority to bind the corporation by any contract or engagement or to
pledge its credit or to render it liable for any purpose or for any amount.

         8.4      STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES

         The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or


                                       22
<PAGE>   27

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

         Certificates for shares shall be of such form and device as the board
of directors may designate and shall state the name of the record holder of the
shares represented thereby; its number; date of issuance; the number of shares
for which it is issued; a summary statement or reference to the powers,
designations, preferences or other special rights of such stock and the
qualifications, limitations or restrictions of such preferences and/or rights,
if any; a statement or summary of liens, if any; a conspicuous notice of
restrictions upon transfer or registration of transfer, if any; a statement as
to any applicable voting trust agreement; if the shares be assessable, or, if
assessments are collectible by personal action, a plain statement of such facts.

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

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

         8.5      SPECIAL DESIGNATION ON CERTIFICATES

         If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences and the relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full 

                                       23
<PAGE>   28

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

         8.6      LOST CERTIFICATES

         Except as provided in this Section 8.6, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time. The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

         8.7      TRANSFER AGENTS AND REGISTRARS

         The board of directors may appoint one or more transfer agents or
transfer clerks, and one or more registrars, each of which shall be an
incorporated bank or trust company -- either domestic or foreign, who shall be
appointed at such times and places as the requirements of the corporation may
necessitate and the board of directors may designate.

         8.8      CONSTRUCTION; DEFINITIONS

         Unless the context requires otherwise, the general provisions, rules of
construction and definitions in the General Corporation Law of Delaware shall
govern the construction of these bylaws. Without limiting the generality of this

                                   ARTICLE IX

                                   AMENDMENTS

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

         Whenever an amendment or new bylaw is adopted, it shall be copied in
the book of bylaws with the original bylaws, in the appropriate place. If any
bylaw is repealed, the fact of repeal with the date of the meeting at which the
repeal was enacted or the filing of the operative written consent(s) shall be
stated in said book.

                  SECTION 3.01. Organization and Standing of the Company. The
Company is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware, and each of the Company's Subsidiaries
is duly organized, validly existing and in good standing under the laws of its
jurisdiction of organization. Each of the Company and its Subsidiaries has all
requisite power and authority and possesses all franchises, licenses, permits,
authorizations and approvals from Governmental Authorities necessary to enable
it to use its corporate name and to own, lease or otherwise hold its properties
and assets and to carry on its business as presently conducted and proposed to
be conducted. Each of the Company and its Subsidiaries is duly qualified to do
business as a foreign corporation in each jurisdiction in which the nature of
its business or the ownership, leasing or holding of its properties or assets
requires qualification and where failure to do so would have a material adverse
effect on the Company. The Company has delivered to IBM true and complete copies
of the Certificate of Incorporation, as amended to date, and the By-laws, as in
effect on the date hereof, of the Company. The share certificate and transfer
books and the minute books of the Company (which have been made available for
inspection by IBM and its representatives) are true and complete.

                  SECTION 3.02. Authority. The Company has all requisite power
and authority to enter into the Operative Agreements to which it is a party, to
issue and sell the IBM Shares and to consummate the other transactions
contemplated thereby. The execution and delivery by the Company of the Operative

transactions contemplated thereby have been duly authorized by all necessary
corporate action on the part of the Company and its stockholders. This Agreement
has been duly executed and delivered by the

Company and constitutes, and the other Operative Agreements to which the Company
is a party, when duly executed by the Company and delivered to IBM will
constitute, the legal, valid and binding obligations of the Company, enforceable
against the Company in accordance with their terms, except as enforcement may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting enforcement of creditors' rights generally and by general equitable
principles. The execution and delivery of this Agreement does not, and the
execution and delivery of the other Operative Agreements and the consummation of
the transactions contemplated hereby and thereby and compliance with the terms
hereof and thereof will not, conflict with, or result in any violation of or
default (with or without notice or lapse of time or both) under, or give rise to
a right of termination, cancelation or acceleration of any obligation or to the
loss of any benefit under, or result in the creation or imposition of any Lien
of any nature whatso ever upon any of the properties or assets of the Company or
any of its Subsidiaries under, (a) any material loan or credit agreement or
note, bond, mortgage, indenture, deed of trust, license, lease, contract,
commitment, agreement, understanding or arrangement to which the Company or any
of its Subsidiaries is a party or by which the Company or any of its
Subsidiaries or any of their respective properties or assets is bound, (b) any
provision of the Restated Certificate of Incorporation or By-laws or (c) any
judgment, order, decree, statute or material law, ordinance, rule or regulation
applicable to the Company or any of its Subsidiaries or any of their respective
properties or assets. No consent, approval, order, license, permit or
authorization of, or registration, declaration, notice to or filing with, any
Governmental Authority or any other Person is required to be obtained or made by
or with respect to the Company or any of its Affiliates in connection with the
execution and delivery of any of the Operative Agreements, the issuance and sale
of the IBM Shares or the consummation of the transactions contemplated hereby.

                  SECTION 3.03. Capital Stock of the Company. (a) The authorized

subject to any preemptive, first refusal or other subscription rights. The
issuance of all the IBM Shares and Common Stock issuable upon conversion thereof
has been duly and validly authorized. All the IBM Shares and Common Stock
issuable upon conversion thereof, when issued in compliance with this Agreement
and the Restated Certificate of Incorporation, will be validly issued, fully
paid and nonassessable and will not have been issued in violation of, and will
not be subject to, any preemptive, first refusal or other subscription rights
and will not result in the antidilution provisions of any security of the
Company becoming applicable. The IBM Shares will represent 11.3% of the Total
Voting Power of the Company as of the Closing Date.

                  (b) Attached to Exhibit G is a true and complete list of the
record holders of all Voting Securities. To the best knowledge of the Company,
each such holder owns all the securities shown to be owned by such holder on
Exhibit G beneficially, free and clear of all Liens. Except as set forth in
Sections 3, 4 and 7.01 through 7.16 of the Stockholders Agreement and as
provided in Sections 7.15 and 8.01(a) hereof, there are no outstanding warrants,
options, rights, securities, agreements, subscriptions, anti-dilution rights,
exchange rights, first refusal rights or other commitments pursuant to which the
Company is or may become obligated to issue, deliver or sell any additional
shares of capital stock of the Company or to issue, grant, extend or enter into
any such warrant, option, right, security, agreement, subscription or other
commitment. Other than as set forth in Section 3 of the Stockholders Agreement
and as provided in Sections 7.16 and 8.01 hereof and the conversion rights of
the Preferred Stock, there are no outstanding options, rights, securities,
agreements or other commitments pursuant to which the Company is or may become
obligated to redeem, repurchase, exchange or otherwise acquire or retire any
shares of capital stock of the Company which are presently outstanding or may be
issued in the future.

                  (c) Other than the rights granted to IBM and certain of the
Company's other stockholders pursuant to the Stockholders Agreement, there are
no outstanding rights

which permit the holder thereof to cause the Company to file a registration
statement under the Securities Act or which permit the holder thereof to include
securities of the Company in a registration statement filed by the Company under
the Securities Act, and there are no outstanding agreements or other commitments
which otherwise relate to the registration of any securities of the Company
under the Securities Act.

                  (d) All securities of the Company heretofore issued and sold
by the Company were issued and sold in compliance with all applicable Federal
and state securities laws. There are no agreements, options, rights or
subscriptions of any kind which governed the prior issuance of voting Securities
of the Company that are still in effect. Assuming that the representations and
warranties of IBM set forth in Sections 4.02 and 4.03 are true and correct, the
offering, issuance and delivery of all the IBM Shares and Common Stock issuable
upon conversion thereof in compliance with this Agreement and the Restated
Certificate of Incorporation will be exempt from the registration and prospectus
delivery requirements of the Securities Act.

                  SECTION 3.04. Equity Interests. The Company's Subsidiaries are

and records of the Company, have been prepared in conformity with generally
accepted accounting principles consistently applied (except to the extent
consistency may be affected by the adoption of Statement of Position 91-1) and
fairly present the financial condition of the Company as of the dates thereof
and the results of its operations for the periods then ended. Adoption of
Statement of Position 91-1 will affect net income by not more than $350,000 for
the year ended December 31, 1991.

                  SECTION 3.06. Undisclosed Liabilities. Neither the Company nor
any of its subsidiaries has any material liabilities or obligations of any

course of business consistent with past practice since the date of the Balance

Subsidiary of the Company is obligated to repurchase, or has agreed to
repurchase, any product previously sold by the Company or such Subsidiary, or
has made any other warranty commitments which are not customary in the industry.

                  SECTION 3.07. Taxes. The Company, and all members of any
affiliated group within the meaning of Section 1504 of the Code (an "Affiliated
Group") of which the Company is or has been a member, has filed or caused to be
filed in a timely manner (within any applicable extension periods) all returns,
reports and forms required to be filed under the Code or under applicable state,
local or foreign laws relating to Taxes (except where any failure would not have
a material adverse effect on the Company and its Subsidiaries taken as a whole)
and has paid or set up adequate reserves for payment of all Taxes required to be
paid with respect to the periods covered by such returns, reports and forms. No
Liens have been filed and no material claims are being asserted in the United
States or, to the best knowledge of the Company after due inquiry, outside the

respect to any Taxes. Neither the Company nor any member of any Affiliated Group
of which the Company is a member is delinquent in the payment of any Taxes or
other governmental charges. No restrictions on assessment or collection of Taxes
have been waived with respect to the Company or any member of any Affiliated
Group of which the Company is a member and neither the Company nor any other
Person has consented to the extension of any statute of limitations with respect

its Subsidiaries have good and marketable title to all assets reflected on the
Balance Sheet or acquired after the date thereof, except those since sold or
otherwise disposed of for fair value in the ordinary course of business
consistent with past practice, in each case free and clear of all Liens except
Permitted Liens. All the tangible personal property owned by the Company and its
Subsidiaries is in all material respects in good operating condition and repair,
ordinary wear and tear excepted, and all personal property leased by the Company
and its Subsidiaries is in all material respects in the condition required of
such property by the terms of the lease applicable thereto during the term of

the Company nor any Subsidiary of the Company is bound by or a party to any
options, licenses or agreements of any kind with respect to the use of

Subsidiary has performed or is performing in all material respects all material

default in any material respect thereunder.

                  SECTION 3.12. Litigation; Decrees. There are no lawsuits,
claims, arbitrations or other proceedings or investigations (a) pending or, to
the best knowledge of the Company, threatened by or against or affecting the
Company or any Subsidiary of the Company or any of their respective properties
or assets, which would have a material adverse effect on the Company and its
Subsidiaries taken as a whole or (b) to the best knowledge of the Company,
pending or threatened by or against any of the officers or employees of the
Company or any Subsidiary of the Company which relate to or involve the
termination of such person's employment with any of such person's former
employers. To the best knowledge of the Company, there is no basis for any such
lawsuit, claim, arbitration or other proceeding or investigation. There is no
outstanding judgment, order or decree of any Governmental Authority or
arbitrator applicable to the Company or any Subsidiary of the Company or, to the
best knowledge of the Company after due inquiry, any of their respective
properties, assets or businesses having, or which, insofar as can be reasonably
foreseen, in the future may have, a material adverse effect on the Company or
its Subsidiaries or their respective businesses as presently conducted or as
presently proposed to be conducted.

                  SECTION 3.13. Absence of Changes or Events. (a) Since the date

                                                                              24
                            Stock Purchase Agreement


instances of noncompliance, individually and in the aggregate, will not have a
material adverse effect on the Company and its Subsidiaries taken as a whole)
with all applicable statutes, laws, ordinances, rules and regulations of any
Governmental Authority and any filing requirements relating thereto, including
laws and regulations relating to environ mental requirements (including
requirements relating to air, water and noise pollution).

                  SECTION 3.15. Certain Employee Matters. (a) All current and
former members of management and key personnel (including all employees involved
in the development of software) of and consultants to the Company and its
Subsidiaries have executed and delivered to the Company or the applicable
Subsidiary a confidential information agreement restricting such person's right
to disclose confidential information of the Company or the applicable
Subsidiary. To the best knowledge of the Company, no officer, director or other
employee of the Company or any of its Subsidiaries is a party to or bound by any
contract (including licenses, covenants or agreements of any nature) or other
commitment or obligation, or subject to any judgment, decree or order of any
Governmental Authority, that may interfere with the use of such directors,
officer's or other employee's best efforts to promote the interests of the
Company, conflict with the business of the Company (as now conducted or as
proposed to be conducted) or the transactions contemplated by the operative
Agreements or have a material adverse effect on the Company. To the best
knowledge of the Company, no activity of any employee of the Company or any of
its Subsidiaries as or while an employee of the Company or such Subsidiary has
caused a material violation of any employment contract, confidentiality
agreement, patent disclosure agreement or other contract or agreement. Neither
the execution and delivery of the Operative Agreements, nor the conduct of the
business of the Company as presently conducted, or as proposed to be conducted,
will conflict with or result in a breach of the terms, conditions or provisions
of, or constitute a default under, any contract, covenant or instrument known to
the Company under which any such employees are now obligated.

                  (b) No employee, agent, consultant or contractor associated
with any of the members of management or key personnel of the Company or its
Subsidiaries who has con tributed to or participated in the conception and
development of Proprietary Rights, including software, of the Company or its
Subsidiaries has asserted or threatened any claim against the Company or the
applicable Subsidiary in

                                                                              25
                            Stock Purchase Agreement


connection with such person's involvement in the conception and development of
the software or other proprietary rights of the Company and its Subsidiaries
and, to the best knowledge of the Company after due inquiry, no such person has
a reasonable basis for any such claim.

                  (c) Neither the Company nor any of the Company's Subsidiaries
nor, to the Company's best knowledge, any of their respective officers or
employees have any patents issued or applications pending for any device,
process, design or invention of any kind now used or needed by the Company or
its Subsidiaries in the furtherance of their business operations as presently
conducted or as proposed to be conducted, which patents or applications have not
been assigned to the Company or its Subsidiaries with such assignment duly
recorded in the United States Patent Office.

                  (d) Since the date of its incorporation, the Company has not
experienced any labor disputes, union organization attempts or work stoppages
due to labor disagreements. The Company and its United States Subsidiaries and,
to the best knowledge of the Company after due inquiry of its Subsidiaries, its
foreign Subsidiaries are in compliance in all material respects with all
applicable laws respecting employment and employment practices, occupational
safety and health standards, terms and conditions of employment and wages and
hours, and are not engaged in any unfair labor practice. There is no unfair
labor practice charge or complaint against the Company or any Subsidiary pending
or threatened before the National Labor Relations Board or any comparable state
agency or authority. There is no labor strike, dispute, request for
representation, slowdown or stoppage actually pending or threatened against or
affecting the Company or any Subsidiary. No question concerning representation
has been raised or is threatened respecting the employees of the Company or any
Subsidiary and no union organizing activities are taking place. No grievance or
arbitration proceeding arising out of or under any collective bargaining
agreement is pending or threatened against the Company or any Subsidiary. There
is no existing collective bargaining agreement or other contract with a labor
union to which the Company or any Subsidiary is a party.

                  SECTION 3.16. Insurance. The Company maintains valid policies
of fire, liability, product liability, workmen's compensation, health and other
forms of insurance with respect to the Company's business. All such policies are
valid, outstanding and enforceable policies and provide insurance coverage for
the properties, assets and operations

                                                                              26

of the Company, of the kinds, in the amounts and against the risks required to
comply with all applicable laws and as are reasonable for the business and
assets of the Company. The Company has not been refused any insurance with
respect to any aspect of the operations of its business nor has its coverage
been limited by any insurance carrier to which it has applied for insurance or
with which it has carried insurance. No notice of cancellation or termination
has been received with respect to any such policy. The activities and operations
of the Company have been conducted in a manner so as to conform in all material
respects to all applicable provisions of such insurance policies.

                  SECTION 3.17. Benefit Plans. (a) Exhibit G sets forth a list
and brief description of all "employee pension benefit plans" (as defined in
Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")), and "employee welfare benefit plans" (as defined in Section 3(l) of
ERISA), maintained, or contributed to, by the Company for the benefit of any
officers or employees of the Company, whether of a legally binding nature or in
the nature of informal understandings. The Company has made available to IBM
true, complete and correct copies of (i) the above mentioned plans and all
bonus, deferred compensation plans or arrangements, and other employee fringe
benefit plans (all the foregoing being herein called "Benefit Plans")
maintained, or contributed to by the Company for the benefit of any officers or
employees of the Company, whether of a legally binding nature or in the nature
of informal understandings, (ii) the most recent annual report on Form 5500
filed with the Internal Revenue Service with respect to any Benefit Plan (if any
such report was required) and (iii) each trust agreement and group annuity
contract relating to any Benefit Plan.

                  (b) The Company is in compliance in all material respects with
the provisions of ERISA and the regulations and published interpretations
thereunder. Neither the Company nor any of its Affiliates maintains any Benefit
Plan which is subject to the provisions of title IV of ERISA. No "reportable
event" (as defined in Section 4043 of ERISA and the regulations thereunder) has
occurred with respect to any Benefit Plan which is subject to the provisions of
Title IV of ERISA and which is maintained for employees of the Company or any of
its Affiliates. There are no unfunded vested liabilities under any such Benefit
Plan.

                  SECTION 3.18. Effect of Transaction. No creditor, supplier,
employee, client or other customer or other

Person having a material business relationship with the Company or any
Subsidiary of the Company has informed the Company or such Subsidiary that such
Person intends to change the relationship because of the transactions
contemplated by this Agreement and the other Operative Agreements.

                  SECTION 3.19. Disclosure. The Company has not knowingly failed
to disclose to IBM any facts material to the Company and its Subsidiaries, taken
as a whole. No representation or warranty of the Company contained in this
Agreement, and no statement contained in any document, certificate or Schedule
furnished or to be furnished by or on behalf of the Company to IBM or any of its
representatives pursuant to any of the Operative Agreements, including the
Initial Business Plan (to the extent it makes representations of a factual
nature, but not any projection of future operating results contained therein),
contains or will contain any untrue statement of a material fact or omits or
will omit to state any material fact necessary, in light of the circumstances
under which it was or will be made, in order to make the statements herein or
therein not misleading or necessary in order to fully and fairly provide the
information purported to be provided in any such document, certificate or
Schedule. There is no fact which the Company has not disclosed to IBM in writing
which materially adversely affects, or (insofar as reasonably can be foreseen)
in the future will materially adversely affect, the Company and its
Subsidiaries, taken as a whole, or the ability of the Company to perform its
obligations under the Operative Agreements or its obligations in respect of any
of the IBM Investment Shares.

                  SECTION 3.20. Key-Person Insurance. After due inquiry, the
Company does not have any reason to believe it cannot obtain the key-person
insurance referred to in Section 7.20.

                                   ARTICLE VII

                      Affirmative Covenants of the Company

                  The Company covenants and agrees with IBM, unless IBM shall
otherwise consent in writing, as follows:

                  SECTION 7.01. Accounting System. The Company shall and shall
cause its Subsidiaries to maintain all their financial records in accordance
with generally accepted accounting principles consistently applied. The Company
shall and shall cause its Subsidiaries to maintain sufficient internal controls
which (i) are at least comparable to those maintained by similarly situated
companies and (ii) in any event are sufficient to allow an audit of the Company
and its Subsidiaries in accordance with generally accepted auditing standards.

                  SECTION 7.02. Periodic Reports; Budgets.
(a) The Company shall furnish to IBM, within 90 days after the end of each
fiscal year of the Company, an audited consolidated balance sheet of the Company
as of the end of such fiscal year and the related audited consolidated
statements of operations, stockholders' equity and cash flows of the Company for
such fiscal year (or similar statements if the foregoing statements change as
the result of changes in generally accepted accounting principles), setting
forth in each case in comparative form the corresponding figures for the
preceding fiscal year and for the budget for the fiscal year just completed
(provided, however, that information as to the budgeted figures need not be
audited), all of which shall fairly present the financial condition of the
Company as of the dates shown and the results of its operations for the periods
then ended. Such financial statements shall be accompanied by the report thereon
of Arthur Andersen & Co., independent certified public accountants for the
Company (or another nationally recognized certified public accounting firm that
may be engaged as the Company's independent public accountant), to the effect
that such financial statements have been prepared in conformity with generally
accepted accounting principles applied on a basis consistent with prior years
(except as otherwise specified in such report). The Company shall conduct its
business so that such report of the independent public accountants shall not
contain any qualifications as to the scope of the audit or with respect to the
Company's compliance with generally accepted accounting principles consistently
applied, except for changes in methods of accounting in which such accountants
concur. The Company

                                                                              34
                            Stock Purchase Agreement


shall also furnish IBM with a copy, when available, of the annual memorandum on
internal accounting controls, as furnished by the independent public
accountants. The Company shall also include with such financial statements a
calculation of primary and fully diluted earnings per share (using methods
generally accepted for non-public companies).

                  (b) The Company shall furnish to IBM, within 45 days after the
end of each fiscal year of the Company, an unaudited consolidated balance sheet
as of the end of such fiscal year and the related unaudited statements of
operations, stockholders' equity and cash flows for such fiscal year (or similar
statements if the foregoing statements change as the result of changes in
generally accepted accounting principles), setting forth in each case in
comparative form the corresponding figures for the preceding fiscal year and for
the budget for the fiscal year just completed, all of which shall fairly present
the financial condition of the Company as of the dates shown and the results of
its operations for the periods then ended. The Company shall also include with
such financial statements a schedule showing the exercise prices of any options
or warrants of the Company and a schedule of sales and repurchases of securities
by the Company showing the amount and type of, and the price received or paid
for, such security and the seller or purchaser, as applicable.

                  (c) The Company shall furnish to IBM, within 30 days after the
end of each fiscal quarter, an unaudited consolidated balance sheet of the
Company as of the end of such quarter and the related unaudited consolidated
statements of operations, stockholders' equity and cash flows of the Company for
such quarter and for the fiscal year to date, setting forth in each case in
comparative form the corresponding figures for the preceding fiscal year and for
the budget for the current fiscal year. All such statements shall be certified
by the chief financial officer of the Company that such statements fairly
present the financial condition of the Company as of the dates shown and the
results of its operations for the periods then ended and that such statements
have been prepared in conformity with generally accepted accounting principles
consistently applied except for normal, recurring, year-end audit adjustments
and the absence of footnotes. No such certification shall impose personal
liability on any person who makes such certification, unless such person
recklessly or with gross negligence makes such certification (the applicable
standard of care being reasonably prudent practices followed by other similarly
situated companies in the same industry).

                  (d) The Company shall furnish to IBM, as soon as practicable
and in any event within 30 days after the end of each calendar month, an
unaudited consolidated balance sheet of the Company as of the end of such month
and the related unaudited consolidated statements of operations and cash flows
of the Company for such month and for the fiscal year to date, setting forth in
each case in comparative form the corresponding figures for the budget for the
current fiscal year. All such statements shall be certified by the chief
financial officer of the Company that such statements fairly present the
financial condition of the Company as of the dates shown and the results of its
operations for the periods then ended and that such statements have been
prepared in conformity with generally accepted accounting principles
consistently applied except for normal, recurring, year-end audit adjustments
and the absence of footnotes. No such certification shall impose personal
liability on any person who makes such certification, unless such person
recklessly or with gross negligence makes such certification (the applicable
standard of care being reasonably prudent practices followed by other similarly
situated companies in the same industry).

                  (e) The Company shall furnish to IBM, as soon as practicable
and in any event not less than 30 days prior to the end of each fiscal year of
the Company, (i) an annual operating budget for the Company, approved by the
Board of Directors, for the succeeding fiscal year, containing projections of
profit and loss, cash flow and ending balance sheets for each month of such
fiscal year and (ii) a business plan for the Company relating to the succeeding
fiscal year approved by the Board of Directors (the "Business Plan" for such
year). Promptly upon preparation thereof, the Company shall furnish to IBM any
other operating budgets or business plans that the Company may prepare and any
revi sions of such previously furnished budgets or business plans.

                  (f) The annual statements and quarterly statements furnished
pursuant to Sections 7.02(b) and (c) shall include a narrative discussion
(consistent with the Company's past practices) prepared by the Company
describing the business operations of the Company during the period covered by
such statements. The monthly statements furnished pursuant to Section 7.02(d)
shall be accompanied by a statement describing any material events, transactions
or deviations from the Company's Business Plan and containing an explanation of
the causes and circumstances thereof.

Offering. 

                  SECTION 7.03. Certificates of Compliance. Concurrently with
the furnishing of the statements pursuant to Sections 7.02(b) and (c), the
Company shall furnish to IBM a certificate of the chief executive officer (or
acting chief executive officer) and the chief financial officer of the Company
stating that to each such officer's best knowledge the Company is not in default
(with or without notice or lapse of time or both) under, and has not breached,
the economic and product delivery terms (including milestones) of either the
Development Incentive Agreement dated September 27, 1990 between the Company and
IBM (as amended to date), or the ISMA Agreement, or if any such default or
breach exists, specifying in detail the nature and period of existence thereof
and what actions the Company has taken and proposes to take with respect
thereto. The Company covenants that promptly after the occurrence of any default
(with or without notice or lapse of time or both) under, or breach of, the
economic and product delivery terms (including milestones) under either the
Development Incentive Agreement dated September 27, 1990 (as amended to date),
or the ISMA Agreement and related agreements, it shall deliver to IBM a
certificate of an officer of the Company specifying in detail the nature and
period of existence thereof and what actions the Company has taken and proposes
to take with respect thereto.

                  SECTION 7.04. Other Reports and Inspection. The Company shall
furnish promptly to IBM copies of any financial statements or financial or other
reports prepared by the Company for or otherwise furnished to or filed with its
stockholders. The Company shall furnish promptly to IBM access at the Company's
Premises to such other documents, reports, financial data and other information
as IBM may reasonably request. The Company shall, upon reasonable prior notice
and during normal business hours, make available to IBM or its representatives
or designees for inspection at the Company's premises all properties, assets,
books of accounts, corporate records and contracts of the Company, and any other
material reasonably requested by IBM, for inspection and shall use its best

                            Stock Purchase Agreement


best efforts in all other respects to assist IBM in becoming familiar with the
Company and its business.

                  SECTION 7.05. Insurance. The Company and its Subsidiaries
shall maintain valid policies of workers' compensation, fire and casualty,
liability and other forms of insurance (to the extent it is commercially
reasonable to carry such other insurance) with financially sound and reputable
insurers in such amounts, with such deductibles and against such risks and
losses as are reasonable for the business and assets of the Company and its
Subsidiaries, and the Company and its Subsidiaries shall maintain such other
insurance as may be required by law. The activities and operations of the
Company and its Subsidiaries shall be conducted in a manner so as to conform in
all material respects to all applicable provisions of such insurance policies.

                  SECTION 7.06. Licenses; Other Property. The Company shall and
shall cause its Subsidiaries to obtain, preserve, renew and keep in full force
and effect all rights, licenses, permits, patents, copyrights, trademarks,
service marks, trade names and other authorizations, from Governmental
Authorities or any other Person, utilized by the Company and its Subsidiaries,
which shall be necessary in any material respect to the conduct of their
business. The Company shall and shall cause its Subsidiaries to maintain and
preserve all property material to the conduct of their business and keep such
property in good repair, working order and condition and from time to time make,
and cause to be made, all needful and proper repairs, renewals, additions,
improvements and replacements thereto necessary in order that the business
carried on in connection therewith may be properly conducted at all times.

                  SECTION 7.07. Material Changes and Other Notices. The Company
shall use its best efforts to promptly notify IBM when it becomes aware of (a)
any material adverse change with respect to the Company and (b) any lawsuit,
claim, proceeding or investigation pending or, to the knowledge of the Company,
threatened, or any judgment, order or decree involving the Company or any
Subsidiary which would have a material adverse effect on the Company.

                  SECTION 7.08. Compliance with Applicable Laws. The Company

                            Stock Purchase Agreement


relating thereto. Such obligation shall include complying in all material
respects with the applicable provisions of ERISA and filing in a timely manner
(within any applicable extension periods) all returns, reports and forms
required to be filed under the Code or under applicable state, local or foreign
laws relating to Taxes and timely paying in full all Taxes required to be paid
in respect of the periods covered by such returns, reports and forms, except to
the extent such statutes, laws, ordinances, rules, regulations, filing
requirements or Taxes are being contested diligently and in good faith by the
Company (and, in the case of Taxes, adequate reserves for payment thereof are
made). The Company shall and shall cause its Subsidiaries to do all things
necessary to preserve, renew and keep in full force and effect and in good
standing its corporate existence and authority necessary to continue its
business.

                  SECTION 7.09. Agreements with Employees. By October 1, 1992,
and continually thereafter, the Company shall and shall cause its Subsidiaries
to cause all members of management and all professional employees of and
consultants to the Company and its Subsidiaries, including all employees and
consultants involved in the development of Proprietary Rights, including
software, to enter into agreements, in form and substance satisfactory to IBM,
relating to (i) Proprietary Rights and pursuant to which either (x) in
accordance with applicable foreign, Federal and state law, the Company or the
applicable Subsidiary will be accorded full, effective, exclusive and original
ownership of all tangible and intangible property thereby arising or (y) there
is conveyed to the Company or the applicable Subsidiary by appropriately
executed instruments of assignment full, effective and exclusive ownership of
all tangible and intangible property thereby arising, (ii) a prohibition on
improper use of proprietary information or trade secrets of former or concurrent
employers and a prohibition on the dissemination of documents and property of
such former and concurrent employers in connection with such person's employment
with the Company or the applicable Subsidiary, (iii) nondisclosure of
confidential information, (iv) assignment of patents, trademarks, copyrights and
Proprietary Rights to the Company and (v) disclosure to the Company of
inventions. The Company will not, and will not permit any Subsidiary of the

will not be unreasonably withheld. Any compensation programs for the Company's
employees shall be subject to the prior approval of the Board of Directors or




<PAGE>   44
                                                                              39
                            Stock Purchase Agreement


the compensation committee thereof. The Company shall provide IBM with a
certificate that this covenant has been met by October 5, 1992.

                  SECTION 7.10. Board of Directors. (a) So long as IBM
beneficially owns Voting Securities representing not less than the IBM Minimum
Equity, IBM shall be entitled to propose one person for nomination as a director
of the Company. The Company agrees to nominate such person for election to the
Board of Directors and to use its best efforts to cause such person to be
elected.

                  (b) At any time that IBM shall not have exercised its right to
propose a person to be nominated by the Company for election as a director, IBM
shall be entitled to designate a nonvoting observer who shall be entitled to
attend all meetings of the Board of Directors and any of its committees and who
shall be provided (i) notice of all meetings of the Board of Directors and any
of its committees (concurrent with the delivery of such notice to directors),
(ii) notice of any action that the Board of Directors or any of its committees
may take by written consent (concurrent with the delivery of such notice to
directors), (iii) promptly delivered copies of all minutes and other records of
action by, and all written information furnished to, the Board of Directors or
any of its committees and (iv) any other information requested by such observer
which a member of the Board of Directors would be entitled to request to
discharge his duties. Such IBM observer shall be entitled to the same rights to
reimbursement for the expense of attendance at meetings as any outside director.

                  (c) After the Closing, the Company covenants that at all times
its By-laws will provide for, and that the Company will maintain, a compensation
committee and an audit committee of the Board of Directors. All the members of
the audit committee and a majority of the members of the compensation committee
shall consist of directors who are independent of and unrelated to, and who are
not members of or employed by, the management of the Company. The compensation
committee shall make recommendations to the Board of Directors regarding
important matters of compensation, including stock options, for officers and
employees of the Company.

                  (d) The obligations of the Company under Sections 7.10(a) and
(b) shall terminate after the Company's Initial Public Offering if IBM no longer
beneficially owns at least 5% of the Actual Voting Power of the Corporation.

                            Stock Purchase Agreement


                  (e) Notwithstanding the foregoing, to the extent permitted by
law, the Company may withhold any information from a board observer or director
which would result in a conflict between the interests of the Company and the
interests of IBM. The Company shall use its best efforts to promptly bring to
the attention of such board observer or director any agenda item that, in the
good faith judgment of the Chairman of the Board of the Company, would result in
such a conflict of interest and the Chairman of the Board may exclude such board
observer or director (or, alternatively, the board observer or director shall be
entitled to exclude himself or herself) from any deliberation or discussion of
the Board of Directors concerning such conflict of interest matter and from the
dissemination of any such information.

                  SECTION 7.11. Use of Proceeds. The Company shall use the
proceeds from the sale of the IBM Shares for the purposes set forth in Schedule
7.11 (including the payment of marketing fees due from the Company to IBM).

                  SECTION 7.12. Obligations. The Company shall and shall cause
each of its Subsidiaries to pay its Indebtedness and other obligations in
accordance with prudent business practice as well as all lawful claims for
labor, materials and supplies or otherwise which, if unpaid, might give rise to
a Lien, other than Permitted Liens, upon its income or profits or in respect of
its property or any part thereof. The Company and its Subsidiaries need not pay
any Indebtedness or obligation which they have a bona fide right to contest and
for which they are diligently pursuing a solution.

                  SECTION 7.13. Management Changes. The Company shall use all
reasonable efforts to select and, subject to IBM's approval, employ a new chief
executive officer as promptly as reasonably practicable.

                  SECTION 7.14. Agreements with Stockholders. The Company shall
use its best efforts to cause all Persons that are or become Significant
Stockholders to become parties to the Stockholders Agreement except for those
stockholders who acquire Voting Securities in a transaction where the
Stockholders Agreement does not require a transferee to enter into the
Stockholders Agreement.

                  SECTION 7.15. IBM Purchase Rights for Excess Options. (a)
Within 30 days after the end of each calendar quarter, the Company shall give
IBM written notice of the




<PAGE>   46
                                                                              41

                            Stock Purchase Agreement


number of Voting Securities issued, delivered or sold during such calendar
quarter pursuant to the Company's Incentive Stock Option Plan or any other
employee stock plan that may be adopted by the Company, other than Permitted
Issuances (the "Excess Options"), and shall offer to sell to IBM and, if such
offer is accepted in writing by IBM within 60 days of receipt, shall sell to
IBM, at a purchase price per share equal to the weighted average exercise price
for the Voting Securities issued or granted during such calendar quarter, up to
and including that amount of such Voting Securities which, if purchased by IBM,
would result in IBM retaining its percentage interest in the Total Voting Power
of the Company that it would have had if the Excess Options issued or granted
during such calendar quarter had not been so issued or granted.

                  (b) The closing of any purchase and sale of Voting Securities
pursuant to this Section 7.15 shall take place on such date, within 30 days
after acceptance by IBM of an offer by the Company, as shall be specified by IBM
in such acceptance.

                  (c) This Section 7.15 shall terminate after the Company's
Initial Public Offering.

                  SECTION 7.16. Repurchase of Shares. (a) It is understood that
IBM has based its decision to purchase the IBM Shares on, among other things,
the Company's business strategy described in Schedule 7.16 (the Company's
"Business Strategy"). Accordingly, if in the reasonable determination of IBM,
the business of the Company is being conducted in a manner that represents a
substantive change from the conduct or the foreseen conduct of the Company's
business as set forth in the Business Strategy (other than differences
specifically consented to in writing by IBM; the date of such determination, the
"Significant Change Date"), then IBM may make an election, by delivery of
written notice to the Company, which notice must be delivered within 90 days of
the Significant Change Date, to require the Company to purchase all (but not
less than all) the Voting Securities of the Company then beneficially owned by
IBM at a purchase price equal to the Repurchase Price as of the date of the
notice for such shares. IBM shall promptly notify the Company in writing of the
Significant Change Date. If the Company duly submits to IBM a written notice of
an intended change in the conduct of the Company's business from that
contemplated by the Business Strategy, which written notice recites that it is
being delivered pursuant to this Section and asks for a response, IBM shall
respond within 60 days of




<PAGE>   47
                                                                              42
                            Stock Purchase Agreement


receipt of such notice indicating whether it consents to such change in business
conduct and, if not, whether it intends to exercise its right to require the
Company to repurchase the capital stock owned by IBM pursuant to this Section if
such change in the conduct of the Company's business is implemented. This
Section 7.16(a) shall terminate on the later to occur of (x) two years from the
Closing and (y) 120 days (or such longer period that IBM is subject to an
agreement not to sell or transfer its shares entered into at the request of an
underwriter) after the Company's Initial Public offering.

                  (b) On the fifth anniversary of the Closing Date and on any
subsequent anniversary thereof, IBM may elect, by delivery of written notice to
the Company not less than 30 days prior to such anniversary, to require the
Company to repurchase on each such date up to one-third of the IBM Investment
Shares beneficially owned by IBM on such fifth anniversary at a purchase price
equal to the Repurchase Price as of the date each relevant notice is given. This
Section 7.16(b) shall terminate 120 days (or such longer period that IBM is
subject to an agreement not to sell or transfer its shares entered into at the
request of an underwriter) after the Company's Initial Public Offering.

                  (c) The Repurchase Price for any shares of capital stock to be
repurchased pursuant to Section 7.16(a) or (b) shall be the greater of: (i) (A)
if the Common Stock is publicly traded, the product of (1) the aggregate number
of shares of Common Stock that IBM elects to require the Company to repurchase
plus the aggregate number of shares of common Stock issuable upon the conversion
of other Voting Securities beneficially owned by IBM that IBM elects to require
the Company to repurchase times (2) the closing price for a share of Common
Stock on the trading day last preceding the date of determination of the
Repurchase Price, as reported on the New York Stock Exchange Composite Tape, or
if not reported thereon, on the principal national securities exchange on which
the Common Stock is listed, or if the Common Stock is not listed on any national
securities exchange, as reported on the NASDAQ National Market System or, if
such security is not included for quotation on the NASDAQ National Market
System, the average of the high and low closing bid and asked prices for a share
of such security on such trading day as reported on NASDAQ or, if such closing
prices shall not be reported on NASDAQ, the average of the closing bid and asked
prices of a share of such security on such trading day as the same shall be
reported by the National Quotation Bureau Incorporated, or (B) if the




<PAGE>   48
                                                                              43

                            Stock Purchase Agreement


Common Stock is not publicly traded, the fair market value of the shares of
capital stock to be repurchased, as determined by an independent, nationally
recognized investment banking firm selected by the Company and IBM (provided
that if IBM and the Company cannot agree on the selection of an investment
banking firm, each shall select one nationally recognized investment banking
firm and the firms thus selected shall jointly select a third nationally
recognized investment banking firm which shall determine such fair market value)
and (ii) the aggregate original purchase price paid by IBM for the shares being
repurchased, plus any declared and unpaid dividends.

                  (d) In the event that IBM delivers a notice of its election
pursuant to Section 7.16(a) or (b) then, on the 45th day after the delivery of
such notice or on such other day as may be mutually agreed to by IBM and the
Company, the Company shall repurchase the shares of capital stock beneficially
owned by IBM specified in such notice. On the date fixed for any such purchase,
IBM shall surrender the certificates representing such shares of capital stock
at the principal office of the Company, against payment of the full amount of
the purchase price therefor in cash or by delivery of a promissory note
described below. If the Company may not legally repurchase part or all of the
capital stock to be repurchased on such date in accordance with applicable
corporate law, it will repurchase whatever shares of capital stock it may
lawfully acquire pursuant to such provisions of corporate law and IBM's right to
require the Company to repurchase any other shares of capital stock shall
survive and may be exercised by IBM on such later date as the Company may be
legally empowered to repurchase such shares. IBM shall continue to be the legal
and beneficial owner of such shares of capital stock until they are repurchased
or otherwise transferred by IBM. At the Company's option, the purchase price to
be paid for the repurchase of shares which may be legally repurchased on any
given date pursuant to Section 7.16(a) may be paid by delivery of a promissory
note of the Company. Such note will be in form and substance satisfactory to
IBM, will bear interest at a fixed rate equal to the prime rate of Chemical Bank
in effect on the day before closing plus 2% per annum, will be secured by assets
reasonably satisfactory to IBM, and the outstanding amount will be payable over
three years.

                  SECTION 7.l7. Payments. Except as otherwise provided herein,

immediately available funds) to such account as IBM may designate in writing at
least two days prior to the date of such payment without any requirement for the
presentation or surrender of the certificates for the IBM Shares or other Voting
Securities held by IBM. Dividend payments shall be made by certified check, bank
check or cashier's check.

                  SECTION 7.18. Exchange, Transfer and Replacement of IBM Share
Certificates. Upon surrender of any certificate representing IBM Shares for
exchange or transfer at the offices of the Company and, in the case of a
proposed transfer, upon receipt of evidence reasonably satisfactory to the
Company that such transfer is in compliance with the Securities Act, the Company
shall, at its expense, issue in exchange therefor new certificates in such
denomination or denominations as may be requested for the same aggregate number
of shares represented by the certificate so surrendered and registered as may be
requested. Upon receipt of evidence reasonably satisfactory to the Company of
the loss, theft, destruction or mutilation of any certificate representing IBM
Shares and, in the case of any such loss, theft or destruction, upon delivery of
an agreement of indemnity reasonably satisfactory to the Company, or, in the
case of any such mutilation, upon surrender and cancelation thereof, the Company
shall, at the expense of IBM, issue a new certificate for the same aggregate
number of shares represented by such lost, stolen, destroyed or mutilated
certificate, as the case may be.

                  SECTION 7.19. Reservation of Shares. The Company shall reserve
and keep available out of its authorized but unissued shares of Common Stock a
sufficient number of such shares to comply with its obligations to issue such
shares to IBM under the terms of this Agreement and the Series E Preferred
Stock.

                  SECTION 7.20. Key-Person Insurance. The Company shall obtain
by October 1, 1992, and thereafter maintain in effect, at the expense of the
Company, key-person life

No such policies need be purchased for the Chief Executive officer, nor shall
any policy for the other executives be continued, if two-thirds of the entire
Board of Directors determines it would be commercially unreasonable to purchase
or maintain such policies. Such insurance policies shall be in addition to any
policies maintained prior to obtaining such policies. The proceeds of the
insurance under such policies shall be held in escrow for the benefit of IBM,
under escrow arrangements satisfactory in form and substance to IBM, for
repurchase of the Company's capital stock beneficially owned by IBM pursuant to
Section 7.16 or 8.01 or to pay indebtedness owed to IBM, at IBM's option, and
otherwise shall be payable to the Company. The Company shall provide IBM with a
certificate from the Company that this covenant has been met by October 5, 1992.

to any footnote disclosing IBM's investment) and (ii) an unqualified report on
such financial statements by the Company's independent certified public
accountants, not later than fourteen days after the Closing.

                  SECTION 7.22. EEOC Filings. The Company shall promptly make
all required Equal Employment Opportunity commission filings.

                                  ARTICLE VIII

                        Negative Covenants of the Company

                  The Company covenants and agrees with IBM that unless IBM
shall otherwise consent in writing:

                  SECTION 8.01. Mergers, Consolidation, Sales of Assets. (a) So
long as IBM beneficially owns Voting Securities representing not less than the
IBM Minimum Equity, the Company shall not enter into any transaction or series
of related transactions that would constitute a Control Transaction (or act
pursuant to an agreement, arrangement or understanding with the Company's
stockholders to the same effect) with any Person unless it complies with the
procedure set forth in this Section 8.01. The Company shall give notice to IBM
(the "First Refusal Notice") at least 30 days prior to agreeing to enter into
any Control Transaction and shall give IBM the first opportunity to enter into
such Control Transaction with the Company (the "Right of First Refusal") in the
manner specified in this Section 8.01.

                  (i) The First Refusal Notice shall specify the identity of the
         potential acquirors (the "Acquirors"), and shall specify the assets of
         the Company proposed to be sold, licensed, leased, exchanged or
         otherwise disposed of and the proposed price to be paid therefor (in
         the case of a sale, license, lease, exchange or other disposition of
         assets), the proposed consideration (in the case of a merger,
         consolidation or other reorganization), the proposed price to be paid
         for the Company's securities (in the case of an issuance by the Company
         of its securities), the proposed terms of payment and the time within
         which the Company proposes to enter into an agreement to consummate
         such Control Transaction, and all other material terms and conditions
         upon which the Company proposes to enter into the Control Transaction
         (the "First Refusal Terms"). Such notice shall include a representation
         of the Company to the effect that the material provisions of such
         transaction have been approved by a majority of the disinterested
         members of the Company's Board of Directors and that the Company
         believes that (if an Acquiror is an Affiliate of the Company) the terms
         and conditions described in the First Refusal Terms are not less
         favorable to the Company than could be obtained on an arm's-length
         basis from unrelated third parties, that to the best knowledge of the
         Company each Acquiror is




<PAGE>   52
                                                                              47
                            Stock Purchase Agreement


         prepared to consummate the proposed Control Transaction and has 
         sufficient financing to consummate the proposed Control Transaction
         on the First Refusal Terms and that the Company has a good faith
         intention to enter into the Control Transaction on the First Refusal
         Terms.

                  (ii) The First Refusal Notice shall constitute an irrevocable
         offer to IBM to enter into such Control Transaction with the Company on
         the First Refusal Terms or terms specified by IBM which include cash to
         the same extent as the First Refusal Terms and in other respects are
         economically equivalent to the First Refusal Terms ("IBM's Equivalent
         Terms"). The Right of First Refusal shall be exercisable by notice from
         IBM to the Company within 30 days after receipt by IBM of the First
         Refusal Notice. Such notice from IBM shall specify IBM's Equivalent
         Terms, if any.

                  (iii) If IBM exercises the Right of First Refusal, then the
         Company shall enter into such Control Transaction with IBM on the First
         Refusal Terms or, if such terms are specified by IBM, on IBM's
         Equivalent Terms. The Company shall use its best efforts to cause any
         required approval of its stockholders for such Control Transaction with
         IBM to be obtained as soon as practicable, and in that connection the
         Board of Directors shall recommend that such stockholders vote in favor
         of such approval and the Company shall use its best efforts to direct
         the voting of all shares for which the Company's management or Board of
         Directors holds proxies or is otherwise entitled to vote in favor of
         such approval. The closing of such Control Transaction shall take place
         on the second Business Day after IBM and the Company shall have
         obtained or made all consents, approvals, orders, licenses, permits and
         authorizations of, and registrations, declarations and filings with,
         any Governmental Authority or any other Person required to be obtained
         or made in connection with the consummation of such Control
         Transaction, but not earlier than 30 days following the date IBM gives
         notice exercising its Right of First Refusal, or on such other date as
         shall be mutually acceptable to IBM and the Company.

                  (iv) If IBM does not exercise the Right of First Refusal with
         respect to any Control Transaction, the Company shall be entitled,
         within three months following the expiration of the period for exercise
         of the Right of First Refusal, to consummate such Control




<PAGE>   53
                                                                              48
                            Stock Purchase Agreement


         Transaction with any of the designated Acquirors upon terms and 
         conditions in the aggregate not more favorable to the Acquiror than
         the First Refusal Terms.

                  (b) IBM shall have the right to require the Company to
repurchase all (but not less than all) of the shares of capital stock of the
Company beneficially owned by IBM upon the occurrence of a Control Transaction
if IBM does not exercise its Right of First Refusal set forth in Section
8.01(a), and such transaction is consummated with a Designated Transferee as the
Acquiror. If a Control Transaction with a Designated Transferee is scheduled to
occur, the Company shall give IBM notice as soon as possible of (and in no event
less than 30 days prior to) the scheduled date of consummation of such
transaction (and shall promptly update such notice, if such scheduled date shall
change). Within 30 days after receipt of such notice from the Company (or if the
Company has failed to give IBM notice of such Control Transaction, within six
months following IBM's discovery of the occurrence of the Control Transaction),
IBM may elect, by notice to the Company, to require the Company to repurchase
all (but not less than all) of the shares of capital stock of the Company then
beneficially owned by IBM, and the Company shall repurchase such shares of
capital stock, at a price equal to the greater of (i) the Offer Price for such
shares of capital stock and (ii) the original purchase price paid by IBM for
such shares of capital stock plus declared and unpaid dividends, if any. If the
Company may not legally repurchase all of the capital stock to be repurchased on
such date in accordance with applicable corporate law, it will repurchase
whatever shares of capital stock it may lawfully acquire pursuant to such
provisions of corporate law and IBM's right to require the Company to repurchase
any other shares of capital stock shall survive and may be exercised by IBM on
such later date as the Company or its successor may be legally empowered to
repurchase such shares. IBM shall continue to be the legal and beneficial owner
of such shares of capital stock until they are repurchased or otherwise
transferred by IBM. Any repurchase pursuant to the provisions of this Section
8.01(b) shall be made on a date to be agreed to by IBM and the Company not later
than 20 days following the consummation by the Company of the Control
Transaction. At the closing of any such repurchase, payment of the purchase
price shall be made by the Company to IBM by crediting such payment (by wire
transfer of immediately available funds) to such account as IBM may designate in
writing at least two Business Days prior to the date of such payment.

                            Stock Purchase Agreement


                  (c) If the Company inquires of IBM about a party to a
potential Control Transaction that may be a Designated Transferee, IBM shall
promptly indicate in writing to the Company whether it deems such party to be a
Designated Transferee and such determination shall be binding upon IBM for
purposes of the potential Control Transaction.

                  (d) This Section shall not apply to Any Control Transaction
with any Person who is not a Designated Transferee that occurs more than 120
days (or such longer period that IBM is subject to an agreement not to sell or
transfer its shares entered into at the request of an underwriter) after the
Company's Initial Public offering.

                  SECTION 8.02. No Restrictions Relating to this Agreement.
Other than customary financial covenants in bank loan or other financing
documents, the Company shall not become a party to or bound by any contract,
indenture, agreement, instrument, charter provision or authorizing resolution
for any series of preferred shares or any note, bond or other security or
evidence of Indebtedness under the terms of which or pursuant to which (i) the
Company's ability to declare or pay dividends on, to make any other
distributions with respect to, or to redeem or repurchase any of, the IBM
Investment Shares will be subject to any restriction that is more restrictive
than the provisions of the Restated Certificate of Incorporation or (ii) the
Company's ability to perform any of its obligations under this Agreement or any
of the other Operative Agreements including its obligations relating to
registration rights and redemption and repurchase of shares of capital stock
beneficially owned by IBM will be restricted.

                  SECTION 8.03. Stock Options. The Company shall not grant any
options or other rights to acquire capital stock of the Company, other than
Permitted Issuances.

Section 9.01. Any address or addressee specified above may be changed by notice
to the other parties in accordance with this Section.

                  SECTION 9.02. Survival of Agreement; Termination. All
covenants, agreements, representations and warranties made by the Company herein
and in the certificates or other documents prepared or delivered in connection
with the Closing shall be considered to have been relied upon by IBM and shall
survive the execution and delivery of this Agreement or such certificate or
other document, the sale and purchase of the IBM Shares and any disposition
thereof, regardless of any investigation made by IBM or on its behalf. This
Agreement shall terminate in its entirety except for the provisions of Sections
9.05, 9.09, 9.13 and 9.14 when IBM (including its Affiliates and assignees under
Section 9.03) no longer beneficially owns any Voting Securities of the Company.

                  SECTION 9.03. Assignment. This Agreement and the rights
hereunder shall not be assignable or transferable by either party (except by
operation of law in connection with a merger, consolidation or sale of
substantially all the assets of such party) without the prior written consent of
the other party hereto; provided that IBM may assign, in its sole discretion,
any or all of its rights, interests and obligations under this Agreement to any
of its Affiliates or to any transferee of IBM Shares, other than a transferee
who shall acquire such IBM Shares in a public offering pursuant to a
registration statement declared effective under the Securities Act or pursuant
to Rule 144 thereunder. Subject to the preceding sentence, this Agreement shall
be binding upon, inure to the benefit of and be enforceable by the parties
hereto and their respective successors and assigns.

                  SECTION 9.04. No Third-Party Beneficiaries. This Agreement is
for the sole benefit of the parties hereto and their permitted assigns and
nothing herein expressed or implied shall give or be construed to give to any
Person, other than the parties hereto and such assigns, any legal or equitable
rights hereunder.

                  SECTION 9.05. Expenses. (a) Whether or not the transactions
contemplated hereby are consummated, all costs and expenses incurred in
connection with this Agreement and the transactions contemplated hereby shall be

in this Agreement. In the event the transactions contemplated hereby are
consummated, the Company agrees to

                            Stock Purchase Agreement


pay stamp and other transfer taxes which may be payable in respect of the
execution and delivery of this Agreement or the issuance of the IBM Shares or
any Common Shares issuable upon conversion thereof.

                  (b) The provisions of this Section 9.05 shall remain operative
and in full force and effect regardless of the expiration of the term of this
Agreement or the consum mation of the transactions contemplated hereby, the
invalidity or unenforceability of any term or provision of this Agreement or the
other Operative Agreements or any investigation made by or on behalf of IBM. All
amounts due under this Section 9.05 shall be payable on written demand therefor.

                  SECTION 9.06. Applicable Law. This Agreement shall be governed
by and construed in accordance with the internal laws of the State of New York
applicable to agreements made and to be performed entirely within such State,
without regard to the conflicts of law principles of such State.

                  SECTION 9.07. Waivers; Amendment. (a) No failure or delay of
IBM in exercising any power or right hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of IBM hereunder are cumulative and are
not exclusive of any rights or remedies which IBM would otherwise have. No
waiver of any provision of this Agreement or consent to any departure by the
Company therefrom shall in any event be effective unless the same shall be
permitted by Section 9.07(b), and then such waiver or consent shall be effective
only in the specific instance and for the purpose for which given. No notice or
demand on the Company in any case shall entitle the Company to any other or
further notice or demand in similar or other circumstances.

                  (b) Neither this Agreement nor any provision hereof may be

entered into by authorized signatories of the Company and IBM. To be effective,

approved, waived or purported to be violated, demonstrate knowledge of the
consequences of the action so taken and be signed by an authorized signatory of
the party making or giving such consent, approval, notice, waiver or demand.

                  SECTION 9.08. Entire Agreement. This Agreement (including the
Exhibits hereto) and the other Operative Agreements constitute the entire
agreement between the parties relative to the subject matter hereof. Any
previous agreement, including any discussion outline, between the parties with
respect to the subject matter hereof, is superseded by this Agreement and the
other Operative Agreements.

                  SECTION 9.09. Waiver of Jury Trial. Each party hereto hereby
waives, to the fullest extent permitted by applicable law, any right it may have
to a trial by jury in respect of any litigation directly or indirectly arising
out of, under or in connection with any of the Operative Agreements. Each party
hereto (a) certifies that no representa tive, agent or attorney of the other
party has represented, expressly or otherwise, that the other party would not,
in the event of litigation, seek to enforce the foregoing waiver and (b)
acknowledges that it and the other party hereto have been induced to enter into

this Section 9.09.

                  SECTION 9.10. Severability. In the event any one or more of
the provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby. The parties shall endeavor in good faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

                  SECTION 9.11. Counterparts. This Agreement may be executed in
one or more counterparts, each of which shall constitute an original but all of
which when taken together shall constitute but one contract, and shall become
effective when one or more such counterparts have been signed by each of the
parties and delivered to the other party.

                  (c) In no event will IBM or the Company be liable to the other
for incidental damages, lost profits, income tax consequences, lost savings or
any other consequential damages, even if such party has been advised of the
possibility of such damages, or for punitive damages, resulting from the breach

                               SYNON CORPORATION

                           INDEMNIFICATION AGREEMENT



         THIS INDEMNIFICATION AGREEMENT ("Agreement") is made as of this ____
day of _________, 1997 by and between SYNON CORPORATION, a Delaware corporation
(the "Company"), and ________________________________________("Indemnitee").

                                    RECITALS

         A.      The Company and Indemnitee recognize the continued difficulty
in obtaining liability insurance for its directors, officers, employees, agents
and fiduciaries, the significant increases in the cost of such insurance and
the general reductions in the coverage of such insurance.

         B.      The Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers,
employees, agents and fiduciaries to expensive litigation risks at the same
time as the availability and coverage of liability insurance has been severely
limited.

         C.      Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, agents and fiduciaries of the Company may not be willing
to continue to serve in such capacities without additional protection.

         D.      The Company desires to attract and retain the services of
highly qualified individuals, such as Indemnitee, to serve the Company and, in
part, in order to induce Indemnitee to continue to provide services to the
Company, wishes to provide for the indemnification and advancing of expenses to
Indemnitee to the maximum extent permitted by law.

         E.      In view of the considerations set forth above, the Company
desires that Indemnitee be indemnified by the Company as set forth herein.

         NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

         1.      Indemnification.

                 (a)      Indemnification of Expenses.  The Company shall
indemnify Indemnitee to the fullest extent permitted by law if Indemnitee was
or is or becomes a party to or witness or 
<PAGE>   2
other participant in, or is threatened to be made a party to or witness or other
participant in, any threatened, pending or completed action, suit, proceeding
or alternative dispute resolution mechanism, or any hearing, inquiry or
investigation that Indemnitee in good faith believes might lead to the
institution of any such action, suit, proceeding or alternative dispute
resolution mechanism, whether civil, criminal, administrative, investigative or
other (hereinafter a "CLAIM") by reason of (or arising in part out of) any
event or occurrence related to the fact that Indemnitee is or was a director,
officer, employee, agent or fiduciary of the Company, or any subsidiary of the
Company, or is or was serving at the request of the Company as a director,
officer, employee, agent or fiduciary of another corporation, partnership,
joint venture, trust or other enterprise, or by reason of any action or
inaction on the part of Indemnitee while serving in such capacity (hereinafter
an "INDEMNIFIABLE EVENT") against any and all expenses (including attorneys'
fees and all other costs, expenses and obligations incurred in connection with
investigating, defending, being a witness in or participating in (including on
appeal), or preparing to defend, be a witness in or participate in, any such
action, suit, proceeding, alternative dispute resolution mechanism, hearing,
inquiry or investigation), judgments, fines, penalties and amounts paid in
settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) of such Claim and any federal,
state, local or foreign taxes imposed on Indemnitee as a result of the actual
or deemed receipt of any payments under this Agreement (collectively,
hereinafter "EXPENSES"), including all interest, assessments and other charges
paid or payable in connection with or in respect of such Expenses.  Such
payment of Expenses shall be made by the Company as soon as practicable but in
any event no later than five days after written demand by Indemnitee therefor
is presented to the Company.

                 (b)      Reviewing Party.  Notwithstanding the foregoing, (i)
the obligations of the Company under Section 1(a) shall be subject to the
condition that the Reviewing Party (as described in Section 10(e) hereof) shall
not have determined (in a written opinion, in any case in which the Independent
Legal Counsel referred to in Section 1(c) hereof is involved) that Indemnitee
would not be permitted to be indemnified under applicable law, and (ii) the
obligation of the Company to make an advance payment of Expenses to Indemnitee
pursuant to Section 2(a) (an "EXPENSE ADVANCE") shall be subject to the
condition that, if, when and to the extent that the Reviewing Party determines
that Indemnitee would not be permitted to be so indemnified under applicable
law, the Company shall be entitled to be reimbursed by Indemnitee (who hereby
agrees to reimburse the Company) for all such amounts theretofore paid;
provided, however, that if Indemnitee has commenced or thereafter commences
legal proceedings in a court of competent jurisdiction to secure a
determination that Indemnitee should be indemnified under applicable law, any
determination made by the Reviewing Party that Indemnitee would not be
permitted to be indemnified under applicable law shall not be binding and
Indemnitee shall not be required to reimburse the Company for any Expense
Advance until a final judicial determination is made with respect thereto (as
to which all rights of appeal therefrom have been exhausted or lapsed).
Indemnitees' obligation to reimburse the Company for any Expense Advance shall
be unsecured and no interest shall be charged thereon.  If there has not been a
Change in Control (as defined in




                                      -2-
<PAGE>   3
Section 10(c) hereof), the Reviewing Party shall be selected by the Board of
Directors, and if there has been such a Change in Control (other than a Change
in Control which has been approved by a majority of the Company's Board of
Directors who were directors immediately prior to such Change in Control), the
Reviewing Party shall be the Independent Legal Counsel referred to in Section
1(c) hereof.  If there has been no determination by the Reviewing Party or if
the Reviewing Party determines that Indemnitee substantively would not be
permitted to be indemnified in whole or in part under applicable law,
Indemnitee shall have the right to commence litigation seeking an initial
determination by the court or challenging any such determination by the
Reviewing Party or any aspect thereof, including the legal or factual bases
therefor, and the Company hereby consents to service of process and to appear
in any such proceeding.  Any determination by the Reviewing Party otherwise
shall be conclusive and binding on the Company and Indemnitee.

                 (c)      Change in Control.  The Company agrees that if there
is a Change in Control of the Company (other than a Change in Control which has
been approved by a majority of the Company's Board of Directors who were
directors immediately prior to such Change in Control) then, with respect to
all matters thereafter arising concerning the rights of Indemnitees to payments
of Expenses and Expense Advances under this Agreement or any other agreement or
under the Company's Certificate of Incorporation or Bylaws as now or hereafter
in effect, Independent Legal Counsel (as defined in Section 10(d) hereof) shall
be selected by Indemnitee and approved by the Company (which approval shall not
be unreasonably withheld).  Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be permitted to be indemnified under applicable law and the
Company agrees to abide by such opinion.  The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully
indemnify such counsel against any and all expenses (including attorneys'
fees), claims, liabilities and damages arising out of or relating to this
Agreement or its engagement pursuant hereto.

                 (d)      Mandatory Payment of Expenses.  Notwithstanding any
other provision of this Agreement other than Section 9 hereof, to the extent
that Indemnitee has been successful on the merits or otherwise, including,
without limitation, the dismissal of an action without prejudice, in defense of
any action, suit, proceeding, inquiry or investigation referred to in Section
(1)(a) hereof or in the defense of any claim, issue or matter therein,
Indemnitee shall be indemnified against all Expenses incurred by Indemnitee in
connection therewith.

         2.      Expenses; Indemnification Procedure.

                 (a)      Advancement of Expenses.  The Company shall advance
all Expenses incurred by Indemnitee.  The advances to be made hereunder shall
be paid by the Company to Indemnitee as soon as practicable but in any event no
later than five days after written demand by Indemnitee therefor to the
Company.





                                      -3-
<PAGE>   4
                 (b)      Notice/Cooperation by Indemnitee.  Indemnitee shall,
as a condition precedent to Indemnitees' right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which indemnification will or could be sought
under this Agreement.  Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee).  In addition, Indemnitee shall give the Company such
information and cooperation as it may reasonably require and as shall be within
Indemnitees' power.

                 (c)      No Presumptions; Burden of Proof.  For purposes of
this Agreement, the termination of any Claim by judgment, order, settlement
(whether with or without court approval) or conviction, or upon a plea of nolo
contendere, or its equivalent, shall not create a presumption that Indemnitee
did not meet any particular standard of conduct or have any particular belief
or that a court has determined that indemnification is not permitted by
applicable law.  In addition, neither the failure of the Reviewing Party to
have made a determination as to whether Indemnitee has met any particular
standard of conduct or had any particular belief, nor an actual determination
by the Reviewing Party that Indemnitee has not met such standard of conduct or
did not have such belief, prior to the commencement of legal proceedings by
Indemnitee to secure a judicial determination that Indemnitee should be
indemnified under applicable law, shall be a defense to Indemnitee's claim or
create a presumption that Indemnitee has not met any particular standard of
conduct or did not have any particular belief.  In connection with any
determination by the Reviewing Party or otherwise as to whether Indemnitee is
entitled to be indemnified hereunder, the burden of proof shall be on the
Company to establish that Indemnitee is not so entitled.

                 (d)      Notice to Insurers.  If, at the time of the receipt
by the Company of a notice of a Claim pursuant to Section 2(b) hereof, the
Company has liability insurance in effect which may cover such Claim, the
Company shall give prompt notice of the commencement of such Claim to the
insurers in accordance with the procedures set forth in the respective
policies.  The Company shall thereafter take all necessary or desirable action
to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as
a result of such action, suit, proceeding, inquiry or investigation in
accordance with the terms of such policies.

                 (e)      Selection of Counsel.  In the event the Company shall
be obligated hereunder to pay the Expenses of any Claim, the Company shall be
entitled to assume the defense of such Claim with counsel approved by
Indemnitee, which approval shall not be unreasonably withheld, upon the
delivery to Indemnitee of written notice of its election so to do.  After
delivery of such notice, approval of such counsel by Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to
Indemnitee under this Agreement for any fees of counsel subsequently incurred
by Indemnitee with respect to the same Claim; provided that, (i) Indemnitee
shall have the right to employ Indemnitees' counsel in any such Claim at





                                      -4-
<PAGE>   5
Indemnitee expense and (ii) if (A) the employment of counsel by Indemnitee has
been previously authorized by the Company, (B) Indemnitee shall have reasonably
concluded that there is a conflict of interest between the Company and
Indemnitee in the conduct of any such defense, or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and
expenses of Indemnitee counsel shall be at the expense of the Company.  The
Company shall have the right to conduct such defense as it sees fit in its sole
discretion, including the right to settle any claim against Indemnitee without
the consent of the Indemnitee.

         3.      Additional Indemnification Rights; Nonexclusivity.

                 (a)      Scope.  The Company hereby agrees to indemnify
Indemnitee to the fullest extent permitted by law, notwithstanding that such
indemnification is not specifically authorized by the other provisions of this
Agreement, the Company's Certificate of Incorporation, the Company's Bylaws or
by statute.  In the event of any change after the date of this Agreement in any
applicable law, statute or rule which expands the right of a Delaware
corporation to indemnify a member of its Board of Directors or an officer,
employee, agent or fiduciary, it is the intent of the parties hereto that
Indemnitee shall enjoy by this Agreement the greater benefits afforded by such
change.  In the event of any change in any applicable law, statute or rule
which narrows the right of a Delaware corporation to indemnify a member of its
Board of Directors or an officer, employee, agent or fiduciary, such change, to
the extent not otherwise required by such law, statute or rule to be applied to
this Agreement, shall have no effect on this Agreement or the parties' rights
and obligations hereunder except as set forth in Section 8(a) hereof.

                 (b)      Nonexclusivity.  The indemnification provided by this
Agreement shall be in addition to any rights to which Indemnitee may be
entitled under the Company's Certificate of Incorporation, its Bylaws, any
agreement, any vote of stockholders or disinterested directors, the General
Corporation Law of the State of Delaware, or otherwise.  The indemnification
provided under this Agreement shall continue as to Indemnitee for any action
Indemnitee took or did not take while serving in an indemnified capacity even
though Indemnitee may have ceased to serve in such capacity.

         4.      No Duplication of Payments.  The Company shall not be liable
under this Agreement to make any payment in connection with any Claim made
against Indemnitee to the extent Indemnitee has otherwise actually received
payment (under any insurance policy, Certificate of Incorporation, Bylaw or
otherwise) of the amounts otherwise indemnifiable hereunder.

         5.      Partial Indemnification.  If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however,
for all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee are entitled.





                                      -5-
<PAGE>   6
         6.      Mutual Acknowledgement.  Both the Company and Indemnitee
acknowledge that in certain instances, Federal law or applicable public policy
may prohibit the Company from indemnifying its directors, officers, employees,
agents or fiduciaries under this Agreement or otherwise.  Indemnitee
understands and acknowledges that the Company has undertaken or may be required
in the future to undertake with the Securities and Exchange Commission to
submit the question of indemnification to a court in certain circumstances for
a determination of the Company's right under public policy to indemnify
Indemnitee.

         7.      Liability Insurance.  To the extent the Company maintains
liability insurance applicable to directors, officers, employees, agents or
fiduciaries, Indemnitee shall be covered by such policies in such a manner as
to provide Indemnitee the same rights and benefits as are accorded to the most
favorably insured of the Company's directors, if Indemnitee is a director; or
of the Company's officers, if Indemnitee is not a director of the Company but
is an officer; or of the Company's key employees, agents or fiduciaries, if
Indemnitee is not an officer or director but is a key employee, agent or
fiduciary.

         8.      Exceptions.  Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

                 (a)      Excluded Action or Omissions.  To indemnify
Indemnitee for Indemnitee's acts, omissions or transactions from which
Indemnitee or the Indemnitee may not be relieved of liability under applicable
law;

                 (b)      Claims Initiated by Indemnitee.  To indemnify or
advance expenses to Indemnitee with respect to Claims initiated or brought
voluntarily by Indemnitee and not by way of defense, except (i) with respect to
actions or proceedings brought to establish or enforce a right to
indemnification under this Agreement or any other agreement or insurance policy
or under the Company's Certificate of Incorporation or Bylaws now or hereafter
in effect relating to Claims for Indemnifiable Events, (ii) in specific cases
if the Board of Directors has approved the initiation or bringing of such
Claim, or (iii) as otherwise required under Section 145 of the Delaware General
Corporation Law, regardless of whether Indemnitee ultimately is determined to
be entitled to such indemnification, advance expense payment or insurance
recovery, as the case may be;

                 (c)      Lack of Good Faith.  To indemnify Indemnitee for any
expenses incurred by Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by Indemnitee
in such proceeding was not made in good faith or was frivolous; or

                 (d)      Claims Under Section 16(b).  To indemnify Indemnitee
for expenses and the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of





                                      -6-
<PAGE>   7
Section 16(b) of the Securities Exchange Act of 1934, as amended, or any
similar successor statute.

         9.      Period of Limitations.  No legal action shall be brought and
no cause of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a
legal action within such two-year period; provided, however, that if any
shorter period of limitations is otherwise applicable to any such cause of
action, such shorter period shall govern.

         10.     Construction of Certain Phrases.

                 (a)      For purposes of this Agreement, references to the
"Company" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed
in a consolidation or merger which, if its separate existence had continued,
would have had power and authority to indemnify its directors, officers,
employees, agents or fiduciaries, so that if Indemnitee is or was a director,
officer, employee, agent or fiduciary of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee, agent or fiduciary of another corporation, partnership,
joint venture, employee benefit plan, trust or other enterprise, Indemnitee
shall stand in the same position under the provisions of this Agreement with
respect to the resulting or surviving corporation as Indemnitee would have with
respect to such constituent corporation if its separate existence had
continued.

                 (b)      For purposes of this Agreement, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on Indemnitee with respect to an employee
benefit plan; and references to "serving at the request of the Company" shall
include any service as a director, officer, employee, agent or fiduciary of the
Company which imposes duties on, or involves services by, such director,
officer, employee, agent or fiduciary with respect to an employee benefit plan,
its participants or its beneficiaries; and if Indemnitee acted in good faith
and in a manner Indemnitee reasonably believed to be in the interest of the
participants and beneficiaries of an employee benefit plan, Indemnitee shall be
deemed to have acted in a manner "not opposed to the best interests of the
Company" as referred to in this Agreement.

                 (c)      For purposes of this Agreement a "Change in Control"
shall be deemed to have occurred if (i) any "person" (as such term is used in
Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended),
other than a trustee or other fiduciary holding securities under an employee
benefit plan of the Company or a corporation owned directly or indirectly by
the stockholders of the Company in substantially the same proportions as their





                                      -7-

ownership of stock of the Company, (A) who is or becomes the beneficial owner,
directly or indirectly, of securities of the Company representing 10% or more
of the combined voting power of the Company's then outstanding Voting
Securities, increases his beneficial ownership of such securities by 5% or more
over the percentage so owned by such person, or (B) becomes the "beneficial
owner" (as defined in Rule 13d-3 under said Act), directly or indirectly, of
securities of the Company representing more than 20% of the total voting power
represented by the Company's then outstanding Voting Securities, (ii) during
any period of two consecutive years, individuals who at the beginning of such
period constitute the Board of Directors of the Company and any new director
whose election by the Board of Directors or nomination for election by the
Company's stockholders was approved by a vote of at least two-thirds of the
directors then still in office who either were directors at the beginning of
the period or whose election or nomination for election was previously so
approved, cease for any reason to constitute a majority thereof, or (iii) the
stockholders of the Company approve a merger or consolidation of the Company
with any other corporation other than a merger or consolidation which would
result in the Voting Securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into Voting Securities of the surviving entity) at least 80% of the
total voting power represented by the Voting Securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation, or
the stockholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company of (in one
transaction or a series of transactions) all or substantially all of the
Company's assets.

                 (d)      For purposes of this Agreement, "Independent Legal
Counsel" shall mean an attorney or firm of attorneys, selected in accordance
with the provisions of Section 1(c) hereof, who shall not have otherwise
performed services for the Company or Indemnitee within the last three years
(other than with respect to matters concerning the rights of Indemnitee under
this Agreement, or of other indemnitees under similar indemnity agreements).

                 (e)      For purposes of this Agreement, a "Reviewing Party"
shall mean any appropriate person or body consisting of a member or members of
the Company's Board of Directors or any other person or body appointed by the
Board of Directors who is not a party to the particular Claim for which
Indemnitee are seeking indemnification, or Independent Legal Counsel.

                 (f)      For purposes of this Agreement, "Voting Securities"

directors.

         12.     Binding Effect; Successors and Assigns.  This Agreement shall
be binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns, including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business and/or assets of the Company, spouses, heirs,
and personal and legal representatives.  The Company shall require and cause
any successor (whether direct or indirect by purchase, merger, consolidation or
otherwise) to all, substantially all, or a substantial part, of the business
and/or assets of the Company, by written agreement in form and substance
satisfactory to Indemnitee, expressly to assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform if no such succession had taken place.  This Agreement
shall continue in effect with respect to Claims relating to Indemnifiable
Events regardless of whether Indemnitee continues to serve as a director,
officer, employee, agent or fiduciary of the Company or of any other enterprise
at the Company's request.

         13.     Attorneys' Fees.  In the event that any action is instituted
by Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, Indemnitee shall be entitled to be paid all Expenses incurred by
Indemnitee with respect to such action, regardless of whether Indemnitee is
ultimately successful in such action, and shall be entitled to the advancement
of Expenses with respect to such action, unless, as a part of such action, a
court of competent jurisdiction over such action determines that each of the
material assertions made by Indemnitee as a basis for such action was not made
in good faith or was frivolous.  In the event of an action instituted by or in
the name of the Company under this Agreement to enforce or interpret any of the
terms of this Agreement, Indemnitee shall be entitled to be paid all Expenses
incurred by Indemnitee in defense of such action (including costs and expenses
incurred with respect to Indemnitee counterclaims and cross-claims made in such
action), and shall be entitled to the advancement of Expenses with respect to
such action, unless, as a part of such action, a court having jurisdiction over
such action determines that each of Indemnitee material defenses to such action
was made in bad faith or was frivolous.

         14.     Notice.  All notices and other communications required or
permitted hereunder shall be in writing, shall be effective when given, and
shall in any event be deemed to be given (a) five (5) days after deposit with

first class mail, postage prepaid, (b) upon delivery, if delivered by hand, (c)
one business day after the business day of deposit with Federal Express or

other party hereto.

         15.     Consent to Jurisdiction.  The Company and Indemnitee each
hereby irrevocably consent to the jurisdiction of the courts of the State of
Delaware for all purposes in connection with any action or proceeding which
arises out of or relates to this Agreement and agree that any action instituted
under this Agreement shall be commenced, prosecuted and continued only in the
Court of Chancery of the State of Delaware in and for New Castle County, which
shall be the exclusive and only proper forum for adjudicating such a claim.

         16.     Severability.  The provisions of this Agreement shall be
severable in the event that any of the provisions hereof (including any
provision within a single section, paragraph or sentence) are held by a court
of competent jurisdiction to be invalid, void or otherwise unenforceable, and
the remaining provisions shall remain enforceable to the fullest extent
permitted by law.  Furthermore, to the fullest extent possible, the provisions
of this Agreement (including, without limitations, each portion of this
Agreement containing any provision held to be invalid, void or otherwise
unenforceable, that is not itself invalid, void or unenforceable) shall be
construed so as to give effect to the intent manifested by the provision held
invalid, illegal or unenforceable.

         17.     Choice of Law.  This Agreement shall be governed by and its
provisions construed and enforced in accordance with the laws of the State of
Delaware, as applied to contracts between Delaware residents, entered into and
to be performed entirely within the State of Delaware, without regard to the
conflict of laws principles thereof.

         18.     Subrogation.  In the event of payment under this Agreement,
the Company shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnitee who shall execute all documents required and
shall do all acts that may be necessary to secure such rights and to enable the
Company effectively to bring suit to enforce such rights.

         19.     Amendment and Termination.  No amendment, modification,
termination or cancellation of this Agreement shall be effective unless it is
in writing signed by both the parties hereto.  No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of
any other provisions hereof (whether or not similar) nor shall such waiver
constitute a continuing waiver.

         20.     Integration and Entire Agreement.  This Agreement sets forth
the entire understanding between the parties hereto and supersedes and merges
all previous written and oral negotiations, commitments, understandings and
agreements relating to the subject matter hereof between the parties hereto.

         21.     No Construction as Employment Agreement.  Nothing contained in
this Agreement shall be construed as giving Indemnitee any right to be retained
in the employ of the Company or any of its subsidiaries.

plan intended to qualify thereunder as a discretionary plan, or (B) a Committee
designated by the Board to administer the Plan, which Committee shall be
constituted in such a manner as to permit the Plan to comply with Rule 16b-3

capacity until otherwise directed by the Board. From time to time the Board may
increase the size of the Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies, however caused, and remove all members of the

respect to directors, non-director officers and Employees who are neither
directors nor officers.

                           (iii)    Administration With Respect to Consultants 
and other Employees. With respect to grants of Options to Employees who are
neither directors nor officers of the

Company, the Plan shall be administered by (A) the Board or (B) a Committee
designated by the Board, which Committee shall be constituted in such a manner
as to satisfy the legal requirements relating to the administration of incentive
stock option plans, if any, of applicable state corporate and securities laws
and of the Code (the "Applicable Laws"). Once appointed, such Committee shall
continue to serve in its designated capacity until otherwise directed by the
Board. From time to time the Board may increase the size of the Committee and
appoint additional members thereof, remove members (with or without cause) and
appoint new members in substitution therefor, fill vacancies, however caused,
and remove all members of the Committee and thereafter directly administer the
Plan, all to the extent permitted by the Applicable Laws.

                  (b)      Powers of the Administrator.  Subject to the 
provisions of the Plan and in the case of a Committee, the specific duties
delegated by the Board to such Committee, the Administrator shall have the
authority, in its discretion:

                           (i)      to determine the Fair Market Value of the 
Common Stock, in accordance with Section 2(j) of the Plan;

                           (ii)     to select the officers and Employees to whom
Options may from time to time be granted hereunder;

                           (iii)    to determine whether and to what extent 
Options are granted hereunder;

                           (iv)     to determine the number of shares of Common
Stock to be covered by each such award granted hereunder;

                           (v)      to approve forms of agreement for use under
the Plan;

                           (vi)     to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder
(including, but not limited to, the share price and any restriction or
limitation, or any vesting acceleration or waiver of forfeiture restrictions
regarding any Option and/or the shares of Common Stock relating thereto, based
in each case on such factors as the Administrator shall determine, in its sole
discretion);

                           (vii)    to determine whether and under what 
circumstances an Option may be settled in cash under subsection 9(f) instead of
Common Stock;

                           (viii)   to reduce the exercise price of any Option 
to the then current Fair Market Value if the Fair Market Value of the Common
Stock covered by such Option shall have declined since the date the Option was
granted; and




                                       -4-

<PAGE>   5

                  (c)      Effect of Committee's Decision.  All decisions, 
determinations and interpretations of the Administrator shall be final and
binding on all optionees and any other holders of any options.

         5.       Eligibility.

                  (a)      Options may be granted only to Employees.  An 
Employee who has been granted an Option may, if he is otherwise eligible, be
granted an additional Option or Options.

                  (b)      Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of the Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary) exceeds $100,000, such excess Options shall be treated as
Nonstatutory Stock Options.

                  (c)      For purposes of Section 5(b), Incentive Stock Options
shall be taken into account in the order in which they were granted, and the
Fair Market Value of the Shares shall be determined as of the time the Option
with respect to such Shares is granted.

                  (d)      The Plan shall not confer upon any Optionee any right
with respect to continuation of employment with the Company, nor shall it
interfere in any way with his right or the Company's right to terminate his
employment at any time, with or without cause.

         6.      Term of Plan. The Plan shall become effective upon the earlier
to occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company as described in Section 17 of the Plan. It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 13 of the Plan.

         7.      Term of Option. The term of each Option shall be the term 
stated in the Option Agreement; provided, however, that in the case of an
Incentive Stock Option, the term shall be no more than ten (10) years from the
date of grant thereof or such shorter term as may be provided in the Option
Agreement. However, in the case of an Option granted to an Optionee who, at the
time the Option is granted, owns stock representing more than ten percent (10%)
of the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the term of the Option shall be five (5) years from the date of
grant thereof or such shorter term as may be provided in the Option Agreement.

         8.       Option Exercise Price and Consideration.

                  (a) The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Board, but shall be subject to the following:




                                       -5-

<PAGE>   6

                           (i)      In the case of an Incentive Stock Option

                                            (A)      granted to an Employee who,
at the time of the grant of such Incentive Stock Option, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the per share exercise price shall be no
less than 110% of the Fair Market Value per Share on the date of grant.

                                            (B)      granted to any Employee, 
the per share exercise price shall be no less than 100% of the Fair Market Value
per Share on the date of grant.

                           (ii)     In the case of a Nonstatutory  Stock Option

                                            (A)      granted to a person who, at
the time of the grant of such Option, owns stock representing more than ten
percent (10%) of the voting power of all classes of stock of the Company or any
Parent or Subsidiary, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of the grant.

                                            (B)      granted to any person, the
per Share exercise price shall be no less than 85% of the Fair Market Value per
Share on the date of grant.

                  (b)      The consideration to be paid for the Shares to be 
issued upon exercise of an Option, including the method of payment, shall be
determined by the Administrator (and, in the case of an Incentive Stock Option,
shall be determined at the time of grant) and may consist entirely of cash,
check, or at the discretion of the Committee, by promissory note or such other
consideration and method of payment for the issuance of Shares to the extent
permitted under Applicable Laws.

         9.       Exercise of Option.

                  (a)      Procedure for Exercise; Rights as a Stockholder. Any
Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Board, including performance criteria with
respect to the Company and/or the Optionee, and as shall be permissible under
the terms of the Plan.

                           An Option may not be exercised for a fraction of a
Share.

                           An Option shall be deemed to be exercised when 
written notice of such exercise has been given to the Company in accordance with
the terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Board, consist
of any consideration and method of payment allowable under Section 8(b) of the
Plan. Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a stockholder shall exist with respect to the Optioned Stock,




                                       -6-

<PAGE>   7

notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

                           Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

                  (b)      Termination of Employment. In the event of 
termination of an Optionee's Continuous Status as an Employee with the Company,
such Optionee may, but only within ninety (90) days (or such other period of
time as is determined by the Board, with such determination in the case of an
Incentive Stock Option being made at the time of grant of the Option and not
exceeding ninety (90) days) after the date of such termination (but in no event
later than the expiration date of the term of such option as set forth in the
Option Agreement), exercise his Option to the extent that Optionee was entitled
to exercise it at the date of such termination. The preceding sentence shall not
apply to Options that are substituted for options to acquire ordinary shares of
Synon Limited granted under the Synon Limited Employee Incentive Share Option
Plan ("Substituted Options"). Instead, an Optionee's Substituted Option shall,
subject to Sections 7, 9(c) and 9(d) herein, expire upon the termination of the
Optionee's Continuous Status as an Employee of the Company; provided, however,
that the Administrator may, in its sole discretion, by written notice given to
an ex-Employee, permit the ex-Employee to exercise Substituted Options during a
period following his or her termination of employment, which period shall not
extend beyond the expiration date contained in the Stock Option Agreement
evidencing such Substituted Option. To the extent that Optionee was not entitled
to exercise the Option (including a Substituted Option, as the case may be) at
the date of such termination, or if Optionee does not exercise such Option to
the extent so entitled within the time specified herein, the Option shall
terminate.

                  (c)      Disability of Optionee. Notwithstanding the 
provisions of Section 9(b) above, in the event of termination of an Optionee's
Continuous Status as an Employee as a result of his total and permanent
disability (as defined in Section 22(e)(3) of the Code), Optionee may, but only
within twelve (12) months from the date of such termination (but in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement), exercise the Option to the extent otherwise entitled to
exercise it at the date of such termination. To the extent that Optionee was not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option to the extent so entitled within the time specified
herein, the Option shall terminate.

                  (d)      Death of Optionee. In the event of the death of an
Optionee, the Option may be exercised, at any time within twelve (12) months
following the date of death (but in no event later than the expiration date of
the term of such Option as set forth in the Option Agreement), by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent the Optionee was entitled to exercise the
Option at the date of death. To the extent that Optionee was not entitled to
exercise the Option at the date of termination,




                                       -7-

<PAGE>   8

or if Optionee does not exercise such Option to the extent so entitled within
the time specified herein, the Option shall terminate.

                  (e)      Rule 16-3. Options granted to persons subject to 
Section 16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain
such additional conditions or restrictions as may be required thereunder to
qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

                  (f)      Buyout Provisions. The Administrator may at any time
offer to buy out for a payment in cash or Shares, an Option previously granted,
based on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

         10.      Non-Transferability of Options.  The Option may not be sold, 
pledged, assigned, hypothecated, transferred, or disposed of in any manner other
than by will or by the laws of descent or distribution and may be exercised,
during the lifetime of the Optionee, only by the Optionee.

         11.     Adjustments Upon Changes in Capitalization or Merger. Subject 
to any required action by the stockholders of the Company, the number of shares
of Common Stock covered by each outstanding Option, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options have yet been granted or which have been returned to the Plan
upon cancellation or expiration of an Option, as well as the price per share of
Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

                  In the event of the proposed dissolution or liquidation of the
Company, the Board shall notify the Optionee at least thirty (30) days prior to
such proposed action. To the extent it has not been previously exercised, the
Option will terminate immediately prior to the consummation of such proposed
action. In the event of a merger of the Company with or into another
corporation, the Option shall be assumed or an equivalent option shall be
substituted by such successor corporation or a parent or subsidiary of such
successor corporation. In the event that such successor corporation does not
agree to assume the Option or to substitute an equivalent option, the Board
shall, in lieu of such assumption or substitution, provide for the Optionee to
have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which the Option would not otherwise be exercisable. If the Board
makes an Option fully exercisable in lieu of assumption or substitution in




                                       -8-

<PAGE>   9

the event of a merger, the Board shall notify the Optionee that the Option shall
be fully exercisable for a period of thirty (30) days from the date of such
notice, and the Option will terminate upon the expiration of such period.

         12.     Time of Granting Options. The date of grant of an Option shall,
for all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Board. Notice
of the determination shall be given to each Employee to whom an Option is so
granted within a reasonable time after the date of such grant.

         13.      Amendment and Termination of the Plan.

                  (a)      Amendment and Termination. The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made which would impair the rights of any
Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act or with Section 422A of the Code (or any other applicable law
or regulation, including the requirements of the NASD or an established stock
exchange), the Company shall obtain stockholder approval of any Plan amendment
in such a manner and to such a degree as required.

                  (b)      Effect of Amendment or Termination. Any such 
amendment or termination of the Plan shall not affect Options already granted
and such Options shall remain in full force and effect as if this Plan had not
been amended or terminated, unless mutually agreed otherwise between the
Optionee and the Board, which agreement must be in writing and signed by the
Optionee and the Company.

         14.      Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

                  As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

         15.      Reservation of Shares.  The Company, during the term of this 
Plan, will at all times reserve and keep available such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.



                                       -9-

<PAGE>   10

                  The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority shall not have been
obtained.

         16.      Agreements.  Options shall be evidenced by written agreements
in such form as the Board shall approve from time to time.

         17.      Stockholder Approval.  Continuance of the Plan shall be 
subject to approval by the stockholders of the Company within twelve (12) months
before or after the date the Plan is adopted. Such stockholder approval shall be
obtained in the degree and manner required under applicable state and federal
law.

         18.     Information to Optionees. The Company shall provide to each
Optionee, during the period for which such Optionee has one or more Options
outstanding, copies of all annual reports and other information which are
provided to all stockholders of the Company. The Company shall not be required
to provide such information if the issuance of Options under the Plan is limited
to key employees whose duties in connection with the Company assure their access
to equivalent information.

                                SYNON CORPORATION

                             STOCK OPTION AGREEMENT


         1.      Grant of Option. Synon Corporation, a Delaware corporation (the
"Company"), hereby grants to the Optionee named in the Notice of Grant (the
"Optionee"), an option (the "Option") to purchase a total number of shares of
Common Stock (the "Shares") set forth in the Notice of Grant, at the exercise
price per share set forth in the Notice of Grant (the "Exercise Price") subject
to the terms, definitions and provisions of the Synon Corporation 1990 Stock
Option Plan (the "Plan") adopted by the Company, which is incorporated herein by
reference. Unless otherwise defined herein, the terms defined in the Plan shall
have the same defined meanings in this Option.

                  If designated an Incentive Stock Option, this Option is
intended to qualify as an Incentive Stock Option as defined in Section 422A of
the Code.

         2.       Exercise of Option.  This Option shall be exercisable during 
its term in accordance with the Exercise Schedule set out in the Notice of Grant
and with the provisions of Section 9 of the Plan as follows:

                  (a)      Right to Exercise.

                           (i)      This Option may not be exercised for a 
fraction of a share.

                           (ii)     In the event of Optionee's death, disability
or other termination of employment, the exercisability of the Option is governed
by Sections 6, 7 and 8 below, subject to the limitation contained in subsection
2(i)(c).

                           (iii)    In no event may this Option be exercised 
after the date of expiration of the term of this Option as set forth in the
Notice of Grant.

                  (b)      Method of Exercise. This Option shall be exercisable
by written notice (in the form attached as Exhibit A) which shall state the
election to exercise the Option, the number of Shares in respect of which the
Option is being exercised, and such other representations and agreements as to
the holder's investment intent with respect to such shares of Common Stock as
may be required by the Company pursuant to the provisions of the Plan. Such
written notice shall be signed by the optionee and shall be delivered in person
or by certified mail to the Secretary of the Company. The written notice shall
be accompanied by payment of the Exercise Price. This Option shall be deemed to
be exercised upon receipt by the Company of Such written notice accompanied by
the Exercise Price.

                  No Shares will be issued pursuant to the exercise of an Option
unless such issuance and such exercise shall comply with all relevant provisions
of law and the requirements of any stock exchange upon which the Shares may then
be listed. Assuming such compliance, for income tax


<PAGE>   12

purposes the Shares shall be considered transferred to the Optionee on the date
on which the Option is exercised with respect to such Shares.

         3.      Optionee's Representations. In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended, at the time this Option is exercised
Optionee shall, if required by the Company, concurrently with the exercise of
all or any portion of this Option, deliver to the Company his Investment
Representation Statement in the form attached hereto as Exhibit B, and shall
read the applicable rules of the Commissioner of Corporations attached to such
Investment Representation Statement.

         4.       Method of Payment.  Payment of the Exercise Price shall be by
any of the following, or a combination thereof, at the election of the Optionee:

                  i.       cash; or

                  ii.      check; or

                  iii.     in the discretion of the Company, by delivery of a
promissory note (the "Note") of Optionee in the amount of the Exercise Price
together with the execution and delivery by the Optionee of the Security
Agreement attached hereto as Exhibit C. The Note shall be in the form attached
hereto as Exhibit D, shall contain the terms and be payable as set forth herein,
shall bear interest at a rate no less than the "applicable federal rate"
prescribed under the Code and its regulations at time of purchase, and shall be
secured by a pledge of the Shares purchased by the Note pursuant to the Security
Agreement.

         5.      Restrictions on Exercise. This Option may not be exercised 
until such time as the Plan has been approved by the shareholders of the
Company, or if the issuance of such Shares upon such exercise or the method of
payment of consideration for such shares would constitute a violation of any
applicable federal or state securities or other law or regulation, including any
rule under Part 207 of Title 12 of the Code of Federal Regulations ("Regulation
G") as promulgated by the Federal Reserve Board. As a condition to the exercise
of this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

         6.      Termination of Employment. In the event of termination of 
Optionee's Continuous Status as an Employee, Optionee may, to the extent
otherwise so entitled at the date of such termination (the "Termination Date"),
exercise this Option during the Termination Period set out in the Notice of
Grant. To the extent that Optionee was not entitled to exercise this Option at
the date of such termination, or if Optionee does not exercise this Option
within the time specified herein, the Option shall terminate.

         7.       Disability of Optionee.  Notwithstanding the provisions of 
Section 6 above, in the event of termination of Optionee's Continuous Status as
an Employee as a result of total and




                                       -2-

<PAGE>   13

permanent disability (as defined in Section 22 (e)(3) of the Code), Optionee
may, but only within twelve (12) months from the date of termination of
employment (but in no event later than the date of expiration of the term of
this Option as set forth in Section 10 below), exercise the Option to the extent
otherwise so entitled at the date of such termination. To the extent that
Optionee was not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such option (to the extent otherwise so entitled)
within the time specified herein, the Option shall terminate.

         8.      Death of Optionee. In the event of the death of Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the date of expiration of the term of this
Option as set forth in Section 10 below), by Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent the Optionee could exercise the Option at the date of death.

         9.      Non-Transferability of Option. This Option may not be
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by him.
The terms of this Option shall be binding upon the executors, administrators,
heirs, successors and assigns of the Optionee.

         10.     Term of Option. This Option may be exercised only within the
term set out in the Notice of Grant, and may be exercised during such term only
in accordance with the Plan and the terms of this Option. The limitations set
out in Section 7 of the Plan regarding Options designated as Incentive Stock
Options and Options granted to more than ten percent (10%) shareholders shall
apply to this Option.

         11.      Tax Consequences.  Set forth below is a brief summary as of
the date of this Option of some of the federal tax consequences of exercise of
this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE
SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE
SHARES.

                  (a)      Exercise of ISO. If this Option qualifies as an ISO,
there will be no regular federal income tax liability upon the exercise of the
Option, although the excess, if any, of the fair market value of the Shares on
the date of exercise over the Exercise Price will be treated as an adjustment to
the alternative minimum tax for federal tax purposes and may subject the
Optionee to the alternative minimum tax in the year of exercise.

                  (b)      Exercise of Nonqualified Stock Option. If this Option
does not qualify as an ISO, there may be a regular federal income tax liability
upon the exercise of the Option. The Optionee will be treated as having received
compensation income (taxable at ordinary income tax rates) equal to the excess,
if any, of the fair market value of the Shares on the date of exercise over the
Exercise Price. The Company will be required to withhold from Optionees
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

                  (c)      Disposition of Shares. In the case of an NSO, if 
Shares are held for at least one year, any gain realized on disposition of the
Shares will be treated as long-term capital gain for federal income tax
purposes. In the case of an ISO, if Shares transferred pursuant to the Option
are held for at least one year after exercise and are disposed of at least two
years after the Date of Grant, any gain realized on disposition of the Shares
will also be treated as capital gain for federal income tax purposes. If Shares
purchased under an ISO are disposed of within such one-year period or within two
years after the Date of Grant, any gain realized on such disposition will be
treated as compensation income (taxable at ordinary income rates) to the extent
of the excess, if any, of the f air market value of the Shares on the date of
exercise (or, if lower, the amount realized on such disposition) over the
Exercise Price.

                  (d)      Notice of Disqualifying Disposition of ISO Shares. If
the Option granted to Optionee herein is an ISO, and if Optionee sells or
otherwise disposes of any of the Shares acquired pursuant to the ISO on or
before the later of (1) the date two years after the Date of Grant, or (2) the
date one year after transfer of such Shares to the Optionee upon exercise of the
ISO, the Optionee shall immediately notify the Company in writing of such
disposition. Optionee agrees that Optionee may be subject to income tax
withholding by the Company on the compensation income recognized

by the Optionee from the early disposition by payment in cash or out of the
current earnings paid to the Optionee.

2.       Commencement

         The Scheme shall commence on the Date of Commencement.

3.       Offer and Grant of Options
<PAGE>   6
         (A)     The Directors may, subject to the Rules, in their absolute
discretion offer Options to Executives.

         (B)     Options may be granted hereunder at any time following the

         (C)     Subject to the limitations hereinafter set out, Options may be
granted to such Executives in such amounts as the Directors shall in their
absolute discretion from time to time determine.  No person shall be entitled
as of right to participate in the Scheme.

         (D)     If the Directors determine to offer participation in the
Scheme to an Executive they shall give him notice in writing of such offer

and accordingly, save in the specific situations described in the Rules where 
the Option may be exercised by personal representatives, shall not be capable of
being transferred, assigned, charged or otherwise encumbered by the Option
Holder.  Any breach of this provision shall entitle the Directors to cancel the
Option.

4.       The Option Price

         The Option Price shall be determined by the Directors but shall in no
event be less than the greater of:-

                 (a)      the nominal value of an Ordinary Share; or

                 (b)      a price equal to the market value (as the same is
                          defined in Section 187 of the Act) of an Ordinary
                          Share on the day prior to the day on which the offer
                          is made as determined by agreement between the
                          Corporation and the Shares Valuation Division of the

                          admitted to the Official List of The Stock Exchange

                          paragraph (b) shall be a price equal to the average
                          of the middle market quotations for an Ordinary Share
                          on The Stock Exchange on the three dealing days
                          immediately prior to the day on which the offer is
                          made as derived from The Stock Exchange Daily
                          Official List and if the Ordinary Shares have been
                          admitted to the New York Stock Exchange the price
                          falling to be determined within this paragraph (b)
                          shall be the closing sales price of such Ordinary
                          Share (or the closing bid, if no sales were reported,
                          as quoted on such exchange) as
<PAGE>   8
                          reported in the Wall Street Journal on the day prior
                          to the date such Option is granted.  The Option Price
                          shall be subject to variation pursuant to Rule 8.

5.       Limitations of the Scheme

         (A)     No Executive shall obtain rights under the Scheme which will,
at the time they are obtained, cause the aggregate market value of the Ordinary
Shares which he may acquire in pursuance of rights obtained under the Scheme or
under any other share option or share incentive scheme approved under Schedule
9 to the Act (as amended from time to time), and any other executive share
option scheme established for any directors or employees of members of the
Group or any associated corporation of the Corporation (as the same is defined
in Section 416 of the Act) and whether exercised or not, to exceed four times
the Executive's Relevant Limit or Pound 100,000 which ever is the greater.
Provided that no account shall be taken of subscription or acquisition moneys
for shares comprised in such options granted more than ten years prior to the
date of the proposed grant of such Option, whether exercised or not.

         (B)     Subject to paragraph 5(C) below the total number of Ordinary
Shares over which Options may be granted at any date under the Scheme shall not
exceed five million (except to the extent that such options have lapsed or been
renounced).

         (C)     The total number of Ordinary Shares over which Options may be
granted under the Scheme at any date, when aggregated with the total number of
Ordinary Shares in respect of which rights of subscription have been granted in
the previous ten years under the Scheme and any other share
<PAGE>   9
option or share incentive scheme established for any directors or employees of
members of the Group (except to the extent to which they have lapsed or been
renounced or released), shall not exceed twenty per cent of the aggregate of
the issued Ordinary Shares and "A" Preferred Stock and Ordinary Shares already
put under option (and which have not lapsed or been renounced or been
exercised) from time to time.

         (D)     No Option may be granted under the Scheme more than ten years
after the Date of Commencement.

6.       Exercise, Lapse and Renunciation of Options

         (A)     Subject to the following provisions of Rule 6(A) a subsisting
Option may only be exercised in whole or in part by an Option Holder during the
seven years following the expiration of a period of three years from the grant
thereof.  Notwithstanding the foregoing but subject to Rule 6(B) below a
subsisting Option may nevertheless be exercised within such three year period
if:-

                 (i)      the Option Holder ceases to be in the full time
                 employment of a member of the Group by reason of his injury,
                 disability, retirement, dismissal by reason of redundancy or
                 because the corporation employing him ceases to be a member of
                 the Group (unless the Option Holder is immediately employed by
                 another member of the Group), in any of which events the
                 Option Holder shall have the right to exercise the Option
                 during the period of three months from the date of such
                 cessation; or

                 (ii)     the Option Holder dies whilst in the full time
                 employment of a member of the Group in which event his legal
                 personal representatives shall have the right to exercise the
                 Option during the period of six months from
<PAGE>   10
                 the date of his death; or

                 (iii)    the Option Holder dies within three months of ceasing
                 to be in the full time employment of a member of the Group for
                 one of the reasons described in (A)(i) above, in which event
                 his legal personal representatives shall have the right to
                 exercise the Option during the period of six months from the
                 date of such cessation; or

                 (iv)     a general offer is made to all the holders of
                 Ordinary Shares (or all such holders other than the offeror
                 and/or any person controlled by the offeror and/or any person
                 acting in association or concert with the offeror) and such
                 offer becomes or is declared unconditional in which event the
                 Option Holder may at any time within three months after the
                 date on which such offer is made exercise without restriction
                 all or any part of his Option; or

                 (v)      notice of a meeting to consider a resolution for the
                 voluntary winding up of the Corporation is given, in which
                 event the Option Holder shall have the right to exercise the
                 Option at any time before the resolution is duly passed or
                 defeated or the meeting concluded or adjourned sine die.

                 (B)      Notwithstanding the terms of Rule 6(A) above an
Option shall lapse automatically insofar as it is capable of exercise if it has
not been exercised by the earlier of:-

                 (i)      the expiration of ten years from the date of grant
                 thereof;

                 (ii)     the expiration of three months from the date on which

                 Group for the reasons described in 6(A)(i) above, the
                 expiration of six months from the date of such cessation;

                 (v)      the date on which an Option Holder is dismissed or
                 leaves the employment of a member of the Group for any reason
                 other than for those reasons or in the circumstances described
                 in 6(A)(i) or 6(A)(ii) above;

                 (vi)     providing that a subsisting Option is not released
                 for a new Option pursuant to Rule 6 (F), three months after
                 the date of any offer in writing given to the holders of

         (C)     It shall be a condition of the Scheme that in the event of the
termination of an Option Holder's full time employment with a member of the
Group (for whatever reason) he shall not be entitled to any compensation
whatsoever by reason of any alteration or determination thereon of his rights
or expectations under the Scheme.

         (D)     An Option Holder may at any time renounce his
<PAGE>   12
Option by serving notice in writing on the Corporation of his intention to so
renounce.  The renunciation shall be effective from the date of receipt of such
notice by the Corporation, upon which date the Option Holder's Option shall be
deemed to have lapsed.

         (E)     No Option may be exercised by an Option Holder at any time
when he is precluded by paragraph 8 of Schedule 9 to the Act from participating
in the Scheme.

         (F)     If any corporation (in this Rule 6(F) referred to as the
acquiring corporation) obtains control of the Corporation as a result of the
event specified in Rule 6(A)(iv) the Directors shall seek the agreement of the
acquiring corporation for Option Holders to release subsisting Options to the
acquiring Corporation in consideration of the acquiring Corporation granting
new Options which relate to shares in the acquiring Corporation or any other
corporation falling within Paragraph 10 of Schedule 9 to the Act.  If such
agreement is obtained every Option Holder shall be entitled to release every
subsisting Option held by him in consideration of the grant of new Option which
satisfies the following conditions and providing that such transfer is within
the appropriate period a set out in Rule 6 (G):-

         (i)     is over shares in the acquiring corporation or a corporation

                 Schedule 9 to the Act (and the term "Ordinary Shares" in these
                 Rules shall thereafter be construed accordingly)

         (ii)    is a right to acquire such number of such common stock as has
                 on acquisition of the new Option an
<PAGE>   13
                 aggregate market value equal to the aggregate market value of 
                 the Ordinary Shares subject to the old Option on its disposal

the period of three months beginning when the offeror has obtained control of
the Corporation and any conditions subject to which the offer is made are
satisfied.

         (H)     Rules 6(F) and 6(G) above apply to all Options granted on or
after the Date of Commencement.

         (I)     The exercise of an Option pursuant to the preceding provisions

13 mean in relation to the new Options, the corporation the share capital of
which includes shares over which new Options have been granted and for the
purposes of Rules 6(D) and 9(D) shall mean Synon Corporation and the acquiring

<PAGE>   14

granted.

7.       Manner of Exercise of Options

         (A)     An Option may be exercised in whole or part by the Option
Holder giving notice in writing to the Corporation stating that the Option is
thereby exercised and the number of Ordinary Shares in respect of which it is
exercised.  With such notice the Option Holder shall forward to the Corporation
in a form acceptable to the Directors the consideration for the Ordinary Shares
in respect of which the Option is exercised calculated by reference to the
Option Price.  An Option (or part thereof) shall be deemed to have been
exercised when the said notice together with the said consideration is received
by the Corporation.  If the consideration is paid other than in cash, such
consideration shall be deemed to have been received by the Corporation upon the
bank of the Corporation confirming that such cash consideration has been
credited to the bank account of the Corporation or to such other account as the
Corporation shall direct.  As soon as practicable and in any event within 30
days of receipt of the said notice and consideration the Corporation will send
or cause to be sent to the Option Holder or his legal personal representatives
(as the case may be) a definitive share certificate for the Ordinary Shares in
respect of which the Option is exercised.

         (B)     Any Ordinary Shares allotted on the exercise of an
<PAGE>   15
Option shall rank pari passu in all respects with the Ordinary Shares in issue
at the date of exercise of such Option and shall participate in all dividends
or other distributions which may be declared, made or paid by reference to a
record date after such date.

         (C)     Any partial exercise of an Option (other than such partial
exercise as completes the exercise of the said Option) shall be in respect of
ten Ordinary Shares or an integral multiple thereof.

8.       Issue or Reorganisation

         In the event of any capitalisation issue or rights issue or any
subdivision or consolidation of the Ordinary Shares or any reduction of the
Ordinary Share capital of the Corporation then the number of Ordinary Shares
comprised in any Option, the number of Ordinary Shares which may be issued or
made available pursuant to rights granted under the Scheme and the Option Price
thereof may be adjusted by the Directors (subject to obtaining prior Board of
Inland Revenue approval to such adjustment) in such manner and with effect from
such date as they may in their absolute discretion determine to be appropriate
Provided that the Auditors shall have confirmed in writing that in their
opinion such adjustments are fair and reasonable.  Any such adjustments shall
be made on the basis that the total moneys originally payable by an Option
Holder on full exercise of his Option rights shall remain unchanged.  

9.       Administration and Amendment

         (A)     The Scheme shall in all respects be administered by the
Directors who may at any time and from time to time by resolution (and without
other formality) amend or augment the
<PAGE>   16
Scheme in any respect Provided that:-

         (i)     no amendment shall operate to affect adversely any rights
         already acquired by an Option Holder under the Scheme;

         (ii)    no amendment may be made except by the Corporation in general
         meeting to nullify or override any of the provisions of Clauses 1(f),
         1(k), 1(1) 1(m) 3(A), 3(B), 3(D), 3(E), 3(F), 4, 5, 6, 7(B), 8 and
         this Clause.

         Notwithstanding anything to the contrary contained herein the
Directors may at any time amend the Scheme in any way to the extent necessary
either to secure the approval of the Scheme by the Board of Inland Revenue or
to ensure that such approval is not withdrawn pursuant to any statutory
modifications to the Act.

         (B)     No amendment or alteration to the Scheme made after it has
been approved under the provisions of Schedule 9 to the Act shall have effect
unless such amendment or alteration has been approved by the Board of Inland
Revenue.

         (C)     The Corporation shall bear the costs of setting up and 
administering the Scheme.

         (D)     The Corporation shall maintain all necessary books of account
and records relating to the Scheme.

         (E)     The Directors shall be entitled to authorise any person to
execute on behalf of an Option Holder, at the request of the Option Holder, any
document relating to the Scheme insofar as such document is required to be
executed pursuant hereto.

10.      Availability of Shares

         Subject to the provisions of this Clause the Corporation shall have
available at all times sufficient authorised but
<PAGE>   17
unissued Ordinary Shares necessary to satisfy Options which have been granted
but not exercised.

         On the exercise of an Option the Directors may satisfy the requirement
for Ordinary Shares by allotment of Ordinary Shares, by purchasing Ordinary
Shares or by such other means as they may determine.

11.      Admission to the Official List

         If at any time prior to exercise of a Subsisting Option the Ordinary
Share capital of the Corporation shall be admitted to the Official List of The
Stock Exchange or if such shares shall be listed for trading on the New York
Stock Exchange the Corporation shall within one month after the date of
exercise of an Option apply to the Council of either above referenced Stock
Exchanges for permission for the Ordinary Shares the subject of such exercise
to be admitted to the Official List or to the New York market as the case may
be.

12.      Termination

         The Directors may at any time resolve not to grant further Options
under the Scheme but the subsisting rights of Option Holders under the Scheme
shall remain in force.

13.      Notices

         (A)     Option Holders shall be entitled while they have subsisting
rights under the Scheme to receive copies of all notices and other documents
sent by the Corporation to its Ordinary Shareholders.

         (B)     Any notice or other communication between the Corporation and
an Option Holder shall be given by sending the same by post or by personal
delivery to, in the case of the Corporation, its principal place of business in
the
<PAGE>   18
United Kingdom and in the case of the Option Holder, his address as notified to
the Corporation from time to time.

                    and Consultants, and

               (b)     Powers of the Administrator.  Subject to the provisions
of the Plan, and in the case of a Committee, subject to the specific duties
delegated by the Board to such Committee, the Administrator shall have the
authority, in its discretion:

                       (i)    to determine the Fair Market Value;

                       (ii)   to select the Service Providers to whom Options 
and Stock Purchase Rights may be granted hereunder;

                       (iii)  to determine the number of shares of Common Stock
to be covered by each Option and Stock Purchase Right granted hereunder;

                       (iv)   to approve forms of agreement for use under the 
Plan;

                       (v)    to determine the terms and conditions, not 
inconsistent with the terms of the Plan, of any Option or Stock Purchase Right
granted hereunder. Such terms and conditions include, but are not limited to,
the exercise price, the time or times when Options or Stock Purchase Rights may
be exercised (which may be based on performance criteria), any vesting
acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Option or Stock Purchase Right of the shares of Common
Stock relating thereto, based in each case on such factors as the Administrator,
in its sole discretion, shall determine;

                       (vi)   to reduce the exercise price of any Option or
Stock Purchase Right to the then current Fair Market Value if the Fair Market
Value of the Common Stock covered by such Option or Stock Purchase Right shall
have declined since the date the Option or Stock Purchase Right was granted;

                       (vii)  to institute an Option Exchange Program;

                       (viii) to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan;

                       (ix)   to prescribe, amend and rescind rules and 
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of qualifying for preferred tax treatment
under foreign tax laws;


                                      -5-
<PAGE>   6

                       (x) to modify or amend each Option or Stock Purchase
Right (subject to Section 15(c) of the Plan), including the discretionary
authority to extend the post-termination exercisability period of Options longer
than is otherwise provided for in the Plan;

                      (xi)    to allow Optionees to satisfy withholding tax 
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined. All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

                     (xii)    to authorize any person to execute on behalf of 
the Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

                    (xiii) to make all other determinations deemed necessary or
advisable for administering the Plan.

               (c)     Effect of Administrator's Decision.  The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

        5.     Eligibility.  Nonstatutory Stock Options and Stock Purchase 
Rights may be granted to Service Providers. Incentive Stock Options may be
granted only to Employees.

        6.     Limitations.

               (a) Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

               (b) Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere in
any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without cause.

               (c)     The following limitations shall apply to grants of 
Options:

                       (i)    No Service Provider shall be granted, in any 
fiscal year of the Company, Options to purchase more than 500,000 Shares.

                       (ii)   In connection with his or her initial service, a
Service Provider may be granted Options to purchase up to an additional
500,000 Shares which shall not count against the limit set forth in subsection
(i) above.

                       (iii)  The foregoing limitations shall be adjusted 
proportionately in connection with any change in the Company's capitalization as
described in Section 13.

                       (iv)   If an Option is cancelled in the same fiscal year
of the Company in which it was granted (other than in connection with a
transaction described in Section 13), the cancelled Option will be counted
against the limits set forth in subsections (i) and (ii) above. For this
purpose, if the exercise price of an Option is reduced, the transaction will be
treated as a cancellation of the Option and the grant of a new Option.

        7. Term of Plan. Subject to Section 19 of the Plan, the Plan shall
become effective upon its adoption by the Board. It shall continue in effect for
a term of ten (10) years unless terminated earlier under Section 15 of the Plan.

        8. Term of Option. The term of each Option shall be stated in the Option
Agreement. In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement. Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option shall be five (5) years from the date of grant or such
shorter term as may be provided in the Option Agreement.

        9.     Option Exercise Price and Consideration.

               (a)     Exercise Price.  The per share exercise price for the 
Shares to be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

                       (i)    In the case of an Incentive Stock Option

                              (A)   granted to an Employee who, at the time the

Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.



                                      -7-
<PAGE>   8
                              (B)   granted to any Employee other than an
Employee described in paragraph (A) immediately above, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

                        (ii)   In the case of a Nonstatutory Stock Option, the
per Share exercise price shall be determined by the Administrator. In the case
of a Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                       (iii)  Notwithstanding the foregoing, Options may be 
granted with a per Share exercise price of less than 100% of the Fair Market
Value per Share on the date of grant pursuant to a merger or other corporate
transaction.

               (b) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

               (c) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. Such
consideration may consist entirely of:

                       (i)    cash;

                       (ii)   check;

                       (iii)  promissory note;

                       (iv)   other Shares which (A) in the case of Shares 
acquired upon exercise of an option, have been owned by the Optionee for more
than six months on the date of surrender, and (B) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised;

                       (v)    consideration received by the Company under a 
cashless exercise program implemented by the Company in connection with the
Plan;

                       (vi)   a reduction in the amount of any Company liability
to the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                       (vii)  any combination of the foregoing methods of 
payment; or 



                                      -8-
<PAGE>   9

                       (viii) such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws.

        10.    Exercise of Option.

               (a) Procedure for Exercise; Rights as a Stockholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

                       An Option shall be deemed exercised when the Company 
receives: (i) written or electronic notice of exercise (in accordance with the
Option Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 13 of the Plan.

                       Exercising an Option in any manner shall decrease the 
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

               (b) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.



                                      -9-
<PAGE>   10

               (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

               (d) Death of Optionee. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the Optionee's will or the laws of descent
or distribution. If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

               (e) Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

        11.    Stock Purchase Rights.

               (a) Rights to Purchase. Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing or electronically, by means of a Notice of Grant,
of the terms, conditions and restrictions related to the offer, including the
number of Shares that the offeree shall be entitled to purchase, the price to be
paid, and the time within which the offeree must accept such offer. The offer
shall be accepted by execution of a Restricted Stock Purchase Agreement in the
form determined by the Administrator.

               (b) Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason 




                                      -10-
<PAGE>   11

(including death or Disability). The purchase price for Shares repurchased
pursuant to the Restricted Stock Purchase Agreement shall be the original price
paid by the purchaser and may be paid by cancellation of any indebtedness of the
purchaser to the Company. The repurchase option shall lapse at a rate determined
by the Administrator.

               (c)     Other Provisions.  The Restricted Stock Purchase 
Agreement shall contain such other terms, provisions and conditions not
inconsistent with the Plan as may be determined by the Administrator in its sole
discretion.

               (d) Rights as a Stockholder. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
stockholder, and shall be a stockholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 13
of the Plan.

        12. Non-Transferability of Options and Stock Purchase Rights. Unless
determined otherwise by the Administrator, an Option or Stock Purchase Right may
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee. If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

        13.    Adjustments Upon Changes in Capitalization, Dissolution, Merger 
or Asset Sale.

               (a) Changes in Capitalization. Subject to any required action by
the stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option or Stock
Purchase Right.



                                      -11-
<PAGE>   12

               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse
as to all such Shares, provided the proposed dissolution or liquidation takes
place at the time and in the manner contemplated. To the extent it has not been
previously exercised, an Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

               (c) Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation refuses to assume or substitute for the Option or
Stock Purchase Right, the Optionee shall fully vest in and have the right to
exercise the Option or Stock Purchase Right as to all of the Optioned Stock,
including Shares as to which it would not otherwise be vested or exercisable. If
an Option or Stock Purchase Right becomes fully vested and exercisable in lieu
of assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option or Stock Purchase Right shall be fully vested and exercisable for a
period of thirty (30) days from the date of such notice, and the Option or Stock
Purchase Right shall terminate upon the expiration of such period. For the
purposes of this paragraph, the Option or Stock Purchase Right shall be
considered assumed if, following the merger or sale of assets, the option or
right confers the right to purchase or receive, for each Share of Optioned Stock
subject to the Option or Stock Purchase Right immediately prior to the merger or
sale of assets, the consideration (whether stock, cash, or other securities or
property) received in the merger or sale of assets by holders of Common Stock
for each Share held on the effective date of the transaction (and if holders
were offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding Shares); provided, however, that if
such consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option or Stock Purchase Right, for each Share
of Optioned Stock subject to the Option or Stock Purchase Right, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

        14. Date of Grant. The date of grant of an Option or Stock Purchase
Right shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator. Notice of the 




                                      -12-
<PAGE>   13

determination shall be provided to each Optionee within a reasonable time after
the date of such grant.

        15.    Amendment and Termination of the Plan.

               (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

               (b) Stockholder Approval. The Company shall obtain stockholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

               (c) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

        16. Conditions Upon Issuance of Shares.

               (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option or Stock Purchase Right unless the exercise of such Option
or Stock Purchase Right and the issuance and delivery of such Shares shall
comply with Applicable Laws and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

               (b) Investment Representations. As a condition to the exercise of
an Option or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required.

        17. Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

        18. Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.




                                      -13-
<PAGE>   14

        19. Stockholder Approval. The Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months after the date the Plan is
adopted. Such stockholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

II.  AGREEMENT

        1. Grant of Option. The Plan Administrator of the Company hereby grants
to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee") an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price"), subject to the terms and
conditions of the Plan, which is incorporated herein by reference. Subject to
Section 15(c) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.

               If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code. However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

        2.     Exercise of Option.

               (a) Right to Exercise. This Option is exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

               (b) Method of Exercise. This Option is exercisable by delivery of
an exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to the [SECRETARY] of the Company. The Exercise
Notice shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by such aggregate
Exercise Price.

               No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

PRESCRIBED UNDER THE CODE AND ITS REGULATIONS AT TIME OF PURCHASE, AND SHALL BE
SECURED BY A PLEDGE OF THE SHARES PURCHASED BY THE NOTE PURSUANT TO THE SECURITY
AGREEMENT].

        4. Non-Transferability of Option. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee. The terms
of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

        5. Term of Option. This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in

               (a) Exercising the Option.

                       (i) Nonstatutory Stock Option. The Optionee may incur
regular federal income tax liability upon exercise of a NSO. The Optionee will
be treated as having received 




                                      -3-
<PAGE>   18

compensation income (taxable at ordinary income tax rates) equal to the excess,
if any, of the Fair Market Value of the Exercised Shares on the date of exercise
over their aggregate Exercise Price. If the Optionee is an Employee or a former
Employee, the Company will be required to withhold from his or her compensation
or collect from Optionee and pay to the applicable taxing authorities an amount
in cash equal to a percentage of this compensation income at the time of
exercise, and may refuse to honor the exercise and refuse to deliver Shares if
such withholding amounts are not delivered at the time of exercise.

                       (ii) Incentive Stock Option. If this Option qualifies as
an ISO, the Optionee will have no regular federal income tax liability upon its
exercise, although the excess, if any, of the Fair Market Value of the Exercised
Shares on the date of exercise over their aggregate Exercise Price will be
treated as an adjustment to alternative minimum taxable income for federal tax
purposes and may subject the Optionee to alternative minimum tax in the year of
exercise. In the event that the Optionee ceases to be an Employee but remains a
Service Provider, any Incentive Stock Option of the Optionee that remains
unexercised shall cease to qualify as an Incentive Stock Option and will be
treated for tax purposes as a Nonstatutory Stock Option on the date three (3)
months and one (1) day following such change of status.

               (b) Disposition of Shares.

                       (i) NSO. If the Optionee holds NSO Shares for at least
one year, any gain

realized on disposition of the Shares will be treated as long-term capital gain
for federal income tax purposes.

                       (ii) ISO. If the Optionee holds ISO Shares for at least
one year after exercise and two years after the grant date, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. If the Optionee disposes of ISO Shares within one year
after exercise or two years after the grant date, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the lesser of (A) the difference
between the Fair Market Value of the Shares acquired on the date of exercise and
the aggregate Exercise Price, or (B) the difference between the sale price of
such Shares and the aggregate Exercise Price. Any additional gain will be taxed
as capital gain, short-term or long-term depending on the period that the ISO
Shares were held.

               (c) Notice of Disqualifying Disposition of ISO Shares. If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii) one
year after the exercise date, the Optionee shall immediately notify the Company
in writing of such disposition. The Optionee agrees that he or she may be
subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.

                                SYNON CORPORATION

                        1997 EMPLOYEE STOCK PURCHASE PLAN

         The following constitute the provisions of the 1997 Employee Stock
Purchase Plan of Synon Corporation.

         1. Purpose. The purpose of the Plan is to provide employees of the
Company and its Designated Subsidiaries with an opportunity to purchase Common
Stock of the Company through accumulated payroll deductions. It is the intention
of the Company to have the Plan qualify as an "Employee Stock Purchase Plan"
under Section 423 of the Internal Revenue Code of 1986, as amended. The
provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

         2.       Definitions.

                  (a) "Board" shall mean the Board of Directors of the Company.

the Company for tax purposes whose customary employment with the Company is at
least twenty (20) hours per week and more than five (5) months in any calendar
year. For purposes of the Plan, the employment relationship shall be treated as
continuing intact while the individual is on sick leave or other leave of
absence approved by the Company. Where the period of leave exceeds 90 days and
the individual's right to reemployment is not guaranteed either by statute or by
contract, the employment relationship shall be deemed to have terminated on the
91st day of such leave.

                  (h) "Enrollment Date" shall mean the first day of each
Offering Period.


<PAGE>   2

stock exchange or a national market system, including without limitation the

its Fair Market Value shall be the closing sales price for such stock (or the
closing bid, if no sales were reported) as quoted on such exchange or system for
the last market trading day prior to the date of determination, as reported in
The Wall Street Journal or such other source as the Administrator deems
reliable, or;

                           (2) If the Common Stock is regularly quoted by a
recognized securities dealer but selling prices are not reported, its Fair
Market Value shall be the mean of the closing bid and asked prices for the
Common Stock on the last market trading day prior to the date of determination,
as reported in The Wall Street Journal or such other source as the Board deems
reliable, or;

                           (3) In the absence of an established market for the
Common Stock, the Fair Market Value thereof shall be determined in good faith by
the Board, or;

                           (4) For purposes of the Enrollment Date of the first
Offering Period under the Plan, the Fair Market Value shall be the initial price
to the public as set forth in the final prospectus included within the

"Registration Statement").

                  (k) "Offering Periods" shall mean the periods of approximately
twelve (12) months during which an option granted pursuant to the Plan may be

on which the Securities and Exchange Commission declares the Company's 
Registration Statement effective and ending on the last Trading Day on or 
before October 31, 1997. The duration and timing of Offering Periods may be 
changed pursuant to Section 4 of this Plan.

                  (l) "Plan" shall mean this 1997 Employee Stock Purchase Plan.

                  (m) "Purchase Price" shall mean an amount equal to 85% of the
Fair Market Value of a share of Common Stock on the Enrollment Date or on the
Exercise Date, whichever is lower.

                  (n) "Purchase Period" shall mean the approximately six month

foreign, of which not less than 50% of the voting shares are held by the Company
or a Subsidiary, whether or not such corporation now exists or is hereafter
organized or acquired by the Company or a Subsidiary.

exchanges and the Nasdaq System are open for trading.

         3.       Eligibility.

                  (a) Any Employee who shall be employed by the Company on a
given Enrollment Date shall be eligible to participate in the Plan.

                  (b) Any provisions of the Plan to the contrary
notwithstanding, no Employee shall be granted an option under the Plan (i) to
the extent that, immediately after the grant, such Employee (or any other person
whose stock would be attributed to such Employee pursuant to Section 424(d) of
the Code) would own capital stock of the Company and/or hold outstanding options
to purchase such stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of the capital stock of the
Company or of any Subsidiary, or (ii) to the extent that his or her rights to
purchase stock under all employee stock purchase plans of the Company and its
subsidiaries accrues at a rate which exceeds Twenty-Five Thousand Dollars
($25,000) worth of stock (determined at the fair market value of the shares at
the time such option is granted) for each calendar year in which such option is
outstanding at any time.

         4. Offering Periods. The Plan shall be implemented by consecutive,
overlapping Offering Periods with a new Offering Period commencing on the first
Trading Day on or after May 1 and November 1 of each year, or on such other date
as the Board shall determine, and continuing thereafter until terminated in
accordance with Section 20 hereof; provided, however, that the first Offering
Period under the Plan shall commence with the first Trading Day on or after the
date on which the Securities and Exchange Commission declares the Company's
Registration Statement effective and ending on the last Trading Day on or before
October 31, 1997. The Board shall have the power to change the duration of
Offering Periods (including the commencement dates thereof) with respect to
future offerings without stockholder approval if such change is announced at
least five (5) days prior to the scheduled beginning of the first Offering
Period to be affected thereafter.




                                      -3-
<PAGE>   4
         5. Participation.

                  (a) An eligible Employee may become a participant in the Plan
by completing a subscription agreement authorizing payroll deductions in the
form of Exhibit A to this Plan and filing it with the Company's payroll office
prior to the applicable Enrollment Date.

                  (b) Payroll deductions for a participant shall commence on the
first payroll following the Enrollment Date and shall end on the last payroll in
the Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

         6. Payroll Deductions.

                  (a) At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding 10% of the Compensation
which he or she receives on each pay day during the Offering Period.

                  (b) All payroll deductions made for a participant shall be
credited to his or her account under the Plan and shall be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

                  (c) A participant may discontinue his or her participation in
the Plan as provided in Section 10 hereof, or may increase or decrease the rate
of his or her payroll deductions during the Offering Period by completing or
filing with the Company a new subscription agreement authorizing a change in
payroll deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

                  (d) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a
participant's payroll deductions may be decreased to zero percent (0%) at any
time during a Purchase Period. Payroll deductions shall recommence at the rate
provided in such participant's subscription agreement at the beginning of the
first Purchase Period which is scheduled to end in the following calendar year,
unless terminated by the participant as provided in Section 10 hereof.

                  (e) At the time the option is exercised, in whole or in part,
or at the time some or all of the Company's Common Stock issued under the Plan
is disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company 




                                      -4-
<PAGE>   5
may, but shall not be obligated to, withhold from the participant's compensation
the amount necessary for the Company to meet applicable withholding obligations,
including any withholding required to make available to the Company any tax
deductions or benefits attributable to sale or early disposition of Common Stock
by the Employee.

         7. Grant of Option. On the Enrollment Date of each Offering Period,
each eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than 
3,000 shares of the Company's Common Stock (subject to any adjustment pursuant
to Section 19) on the Enrollment Date, and provided further that such purchase
shall be subject to the limitations set forth in Sections 3(b) and 12 hereof.
Exercise of the option shall occur as provided in Section 8 hereof, unless the
participant has withdrawn pursuant to Section 10 hereof. The option shall expire
on the last day of the Offering Period.

         8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

         9. Delivery. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

         10. Withdrawal.

                  (a) A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time by giving written notice to the
Company in the form of Exhibit B to this Plan. All of the participant's payroll
deductions credited to his or her account shall be paid to such participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the 




                                      -5-
<PAGE>   6
beginning of the succeeding Offering Period unless the participant delivers to
the Company a new subscription agreement.

                  (b) A participant's withdrawal from an Offering Period shall
not have any effect upon his or her eligibility to participate in any similar
plan which may hereafter be adopted by the Company or in succeeding Offering
Periods which commence after the termination of the Offering Period from which
the participant withdraws.

         11. Termination of Employment.

                  Upon a participant's ceasing to be an Employee, for any
reason, he or she shall be deemed to have elected to withdraw from the Plan and
the payroll deductions credited to such participant's account during the
Offering Period but not yet used to exercise the option shall be returned to
such participant or, in the case of his or her death, to the person or persons
entitled thereto under Section 15 hereof, and such participant's option shall be
automatically terminated. The preceding sentence notwithstanding, a participant
who receives payment in lieu of notice of termination of employment shall be
treated as continuing to be an Employee for the participant's customary number
of hours per week of employment during the period in which the participant is
subject to such payment in lieu of notice.

         12. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

         13. Stock.

                  (a) Subject to Section 19, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be 400,000 shares, plus an annual increase to be added on each
anniversary date of the adoption of the Plan equal to the lesser of (i) 150,000
shares, (ii) 1% of the outstanding shares on such date or (iii) a lesser
amount determined by the Board. If, on a given Exercise Date, the number of
shares with respect to which options are to be exercised exceeds the number of
shares then available under the Plan, the Company shall make a pro rata
allocation of the shares remaining available for purchase in as uniform a manner
as shall be practicable and as it shall determine to be equitable.

                  (b) The participant shall have no interest or voting right in
shares covered by his option until such option has been exercised.

                  (c) Shares to be delivered to a participant under the Plan
shall be registered in the name of the participant or in the name of the
participant and his or her spouse.

         14. Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made 



                                      -6-
<PAGE>   7
by the Board or its committee shall, to the full extent permitted by law, be
final and binding upon all part ies.

         15. Designation of Beneficiary.

                  (a) A participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to an Exercise Date on which the option is exercised but prior to
delivery to such participant of such shares and cash. In addition, a participant
may file a written designation of a beneficiary who is to receive any cash from
the participant's account under the Plan in the event of such participant's
death prior to exercise of the option. If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.

                  (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

         16. Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

         17. Use of Funds. All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

         18. Reports. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

         19. Adjustments Upon Changes in Capitalization, Dissolution,
Liquidation, Merger or Asset Sale.

<PAGE>   8
                  (a) Changes in Capitalization. Subject to any required action
by the stockholders of the Company, the Reserves, the maximum number of shares
each participant may purchase each Purchase Period (pursuant to Section 7), as
well as the price per share and the number of shares of Common Stock covered by
each option under the Plan which has not yet been exercised shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of shares of Common Stock effected without
receipt of consideration by the Company; provided, however, that conversion of
any convertible securities of the Company shall not be deemed to have been
"effected without receipt of consideration". Such adjustment shall be made by
the Board, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an option.

                  (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

                  (c) Merger or Asset Sale. In the event of a proposed sale of
all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation, each outstanding option shall be
assumed or an equivalent option substituted by the successor corporation or a
Parent or Subsidiary of the successor corporation. In the event that the
successor corporation refuses to assume or substitute for the option, any
Purchase Periods then in progress shall be shortened by setting a new Exercise
Date (the "New Exercise Date") and any Offering Periods then in progress shall
end on the New Exercise Date. The New Exercise Date shall be before the date of
the Company's proposed sale or merger. The Board shall notify each participant
in writing, at least ten (10) business days prior to the New Exercise Date, that
the Exercise Date for the participant's option has been changed to the New
Exercise Date and that the participant's option shall be exercised automatically
on the New Exercise Date, unless prior to such date the participant has
withdrawn from the Offering Period as provided in Section 10 hereof.

         20. Amendment or Termination.

                  (a) The Board of Directors of the Company may at any time and
for any reason terminate or amend the Plan. Except as provided in Section 19
hereof, no such termination can affect 




                                      -8-
<PAGE>   9
options previously granted, provided that an Offering Period may be terminated
by the Board of Directors on any Exercise Date if the Board determines that the
termination of the Plan is in the best interests of the Company and its
stockholders. Except as provided in Section 19 hereof, no amendment may make any
change in any option theretofore granted which adversely affects the rights of
any participant. To the extent necessary to comply with Section 423 of the Code
(or any successor rule or provision or any other applicable law, regulation or
stock exchange rule), the Company shall obtain stockholder approval in such a
manner and to such a degree as required.

                  (b) Without stockholder consent and without regard to whether
any participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

         21. Notices. All notices or other communications by a participant to
the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.

         22. Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

             As a condition to the exercise of an option, the Company may
require the person exercising such option to represent and warrant at the time
of any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

         23. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.




                                      -9-
<PAGE>   10
         24. Automatic Transfer to Low Price Offering Period. To the extent
permitted by any applicable laws, regulations, or stock exchange rules if the
Fair Market Value of the Common Stock on any Exercise Date in an Offering Period
is lower than the Fair Market Value of the Common Stock on the Enrollment Date
of such Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise
of their option on such Exercise Date and automatically re-enrolled in the
immediately following Offering Period as of the first day thereof.

                             SUBSCRIPTION AGREEMENT

_____ Original Application                          Enrollment Date: ___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)

1.       ________________ hereby elects to participate in the Synon Corporation
         1997 Employee Stock Purchase Plan (the "Employee Stock Purchase Plan")
         and subscribes to purchase shares of the Company's Common Stock in
         accordance with this Subscription Agreement and the Employee Stock
         Purchase Plan.

2.       I hereby authorize payroll deductions from each paycheck in the amount
         of ____% of my Compensation on each payday (from 0 to 10%) during the
         Offering Period in accordance with the Employee Stock Purchase Plan.
         (Please note that no fractional percentages are permitted.)

3.       I understand that said payroll deductions shall be accumulated for the
         purchase of shares of Common Stock at the applicable Purchase Price
         determined in accordance with the Employee Stock Purchase Plan. I
         understand that if I do not withdraw from an Offering Period, any
         accumulated payroll deductions will be used to automatically exercise
         my option.

4.       I have received a copy of the complete Employee Stock Purchase Plan. I
         understand that my par ticipation in the Employee Stock Purchase Plan
         is in all respects subject to the terms of the Plan. I understand that
         my ability to exercise the option under this Subscription Agreement is
         subject to stockholder approval of the Employee Stock Purchase Plan.

5.       Shares purchased for me under the Employee Stock Purchase Plan should
         be issued in the name(s) of (Employee or Employee and Spouse only):
         _________________________________________________.

6.       I understand that if I dispose of any shares received by me pursuant to
         the Plan within 2 years after the Enrollment Date (the first day of the
         Offering Period during which I purchased such shares) or one year after
         the Exercise Date, I will be treated for federal income tax purposes as
         having received ordinary income at the time of such disposition in an
         amount equal to the excess of the fair market value of the shares at
         the time such shares were purchased by me over the price which I paid
         for the shares. I hereby agree to notify the Company in writing within
         30 days after 




<PAGE>   12

         the date of any disposition of my shares and I will make other tax
         withholding obligations, if any, which arise upon the disposition of
         the Common Stock. The Company may, but will not be obligated to,
         withhold from my compensation the amount necessary to meet any
         applicable withholding obligation including any withholding necessary
         to make available to the Company any tax deductions or benefits
         attributable to sale or early disposition of Common Stock by me. If I
         dispose of such shares at any time after the expiration of the 2-year
         and 1-year holding periods, I understand that I will be treated for
         federal income tax purposes as having received income only at the time
         of such disposition, and that such income will be taxed as ordinary
         income only to the extent of an amount equal to the lesser of (1) the
         excess of the fair market value of the shares at the time of such
         disposition over the purchase price which I paid for the shares, or (2)
         15% of the fair market value of the shares on the first day of the
         Offering Period. The remainder of the gain, if any, recognized on such
         disposition will be taxed as capital gain.

7.       I hereby agree to be bound by the terms of the Employee Stock Purchase
         Plan. The effectiveness of this Subscription Agreement is dependent
         upon my eligibility to participate in the Employee Stock Purchase Plan.

8.       In the event of my death, I hereby designate the following as my
         beneficiary(ies) to receive all payments and shares due me under the
         Employee Stock Purchase Plan:

         4. Administration and Grants of Options under the Plan.

                  (a) Procedure for Grants. All grants of Options to Outside
Directors under this Plan shall be automatic and nondiscretionary and shall be
made strictly in accordance with the following provisions:

                           (i) No person shall have any discretion to select
which Outside Directors shall be granted Options or to determine the number of
Shares to be covered by Options granted to Outside Directors.

                           (ii) Each Outside Director shall be automatically
granted an Option to purchase [_____] Shares (the "First Option") on the date on
which the later of the following events occurs: (A) the effective date of this
Plan, as determined in accordance with Section 6 hereof, or (B) the date on
which such person first becomes an Outside Director, whether through election by
the stockholders of the Company or appointment by the Board to fill a vacancy;
provided, however, that an Inside Director who ceases to be an Inside Director
but who remains a Director shall not receive a First Option.

                           (iii) Each Outside Director shall be automatically
granted an Option to Purchase 5,000 shares (a "Subsequent Option") at the first
meeting of the Board of Directors following the annual meeting of stockholders
in each year beginning with the 1997 Annual Meeting of Stockholders, provided he
or she is then an outside director and if as of such date, he or she shall have
served on the Board for at least the preceding six (6) months.

                           (iv) Notwithstanding the provisions of subsections
(ii) and (iii) hereof, any exercise of an Option granted before the Company
has obtained stockholder approval of the Plan in accordance with Section 16
hereof shall be conditioned upon obtaining such stockholder approval of the Plan
in accordance with Section 16 hereof.

                           (v) The terms of a First Option granted hereunder
shall be as follows:

ten (10) years.

                                    (B) the First Option shall be exercisable
only while the Outside Director remains a Director of the Company, except as set
forth in Sections 8 and 10 hereof.

                                    (C) the exercise price per Share shall be
100% of the Fair Market Value per Share on the date of grant of the First
Option. In the event that the date of grant of the First Option is not a trading
day, the exercise price per Share shall be the Fair Market Value on the next
trading day immediately following the date of grant of the First Option.

                                    (D) Subject to Section 10 hereof, the first
option shall become exercisable as to 25% percent of the shares subject to the
first option on the first anniversary 




                                      -3-

of its date of grant, and 1/48th of the shares subject to option shall vest each
month thereafter, provided that the optionee continues to serve as a director 
on such dates.

                           (vi) The terms of a subsequent option granted 
hereunder shall be as follows:

                                    (A) The term of the subsequent option shall
be ten (10) years.

                                    (B) The subsequent option shall be
exercisable only while the outside director remains a director of the Company,
except as set forth in Sections 8 and 10 hereof.

                                    (C) The exercise price per share shall be
100% of the fair market value per share on the date of grant of the subsequent
option. in the event that the date of grant of the subsequent option is not a
trading day, the exercise price per share shall be the fair market value on the
next trading day immediately following the date of grant of the subsequent
option.

                                    (D) Subject to Section 10 hereof, the
subsequent option shall become exercisable as to 25 percent of the shares
subject to the subsequent option on the first anniversary of its date of grant,
and 1/48th of the shares subject to option shall vest each month thereafter,
provided that the optionee continues to serve as a director on such dates.

                           (vii) In the event that any Option granted under the
Plan would cause the number of Shares subject to outstanding Options plus the
number of Shares previously purchased under Options to exceed the Pool, then the
remaining Shares available for Option grant shall be granted under Options to
the Outside Directors on a pro rata basis. No further grants shall be made until
such time, if any, as additional Shares become available for grant under the
Plan through action of the Board or the stockholders to increase the number of
Shares which may be issued under the Plan or through cancellation or expiration
of Options previously granted hereunder.

         5. Eligibility. Options may be granted only to Outside Directors. All
Options shall be automatically granted in accordance with the terms set forth in
Section 4 hereof.

            The Plan shall not confer upon any Optionee any right with respect
to continuation of service as a Director or nomination to serve as a Director,
nor shall it interfere in any way with any rights which the Director or the
Company may have to terminate the Director's relationship with the Company at
any time.

         6. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board or its approval by the stockholders of the
Company as described in Section 16 





                                      -4-
<PAGE>   5
of the Plan. It shall continue in effect for a term of ten (10) years unless
sooner terminated under Section 11 of the Plan.

         7. Form of Consideration. The consideration to be paid for the Shares
to be issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other shares which (x) in the case of
Shares acquired upon exercise of an Option, have been owned by the Optionee for
more than six (6) months on the date of surrender, and (y) have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which said Option shall be exercised, (iv) consideration received
by the Company under a cashless exercise program implemented by the Company in
connection with the Plan, or (v) any combination of the foregoing methods of
payment.

         8. Exercise of Option.

                  (a) Procedure for Exercise; Rights as a Stockholder. Any
Option granted hereunder shall be exercisable at such times as are set forth in
Section 4 hereof; provided, however, that no Options shall be exercisable until
stockholder approval of the Plan in accordance with Section 16 hereof has been
obtained.

                  An Option may not be exercised for a fraction of a Share.

                  An Option shall be deemed to be exercised when written notice
of such exercise has been given to the Company in accordance with the terms of
the Option by the person entitled to exercise the Option and full payment for
the Shares with respect to which the Option is exercised has been received by
the Company. Full payment may consist of any consideration and method of payment
allowable under Section 7 of the Plan. Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
A share certificate for the number of Shares so acquired shall be issued to the
Optionee as soon as practicable after exercise of the Option. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date the stock certificate is issued, except as provided in Section 10 of
the Plan.

                  Exercise of an Option in any manner shall result in a decrease
in the number of Shares which thereafter may be available, both for purposes of
the Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

                  (b) Termination of Continuous Status as a Director. Subject to
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or total and permanent disability (as
defined in Section 22(e)(3) of the Code)), the Optionee may exercise his or her
Option, but only within three (3) months following the date of such termination,
and only to the extent that the Optionee was entitled to exercise it on the date
of such termination 




                                      -5-
<PAGE>   6
(but in no event later than the expiration of its ten (10) year term). To the
extent that the Optionee was not entitled to exercise an Option on the date of
such termination, and to the extent that the Optionee does not exercise such
Option (to the extent otherwise so entitled) within the time specified herein,
the Option shall terminate.

                  (c) Disability of Optionee. In the event Optionee's status as
a Director terminates as a result of total and permanent disability (as defined
in Section 22(e)(3) of the Code), the Optionee may exercise his or her Option,
but only within twelve (12) months following the date of such ter mination, and
only to the extent that the Optionee was entitled to exercise it on the date of
such termination (but in no event later than the expiration of its ten (10) year
term). To the extent that the Optionee was not entitled to exercise an Option on
the date of termination, or if he or she does not exercise such Option (to the
extent otherwise so entitled) within the time specified herein, the Option shall
terminate.

                  (d) Death of Optionee. In the event of an Optionee's death,
the Optionee's estate or a person who acquired the right to exercise the Option
by bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

         9. Non-Transferability of Options. Unless determined otherwise by the
Board, an Option may not be sold, pledged, assigned, hypothecated, transferred,
or disposed of in any manner other than by will or by the laws of descent or
distribution and may be exercised, during the lifetime of the Optionee, only by
the Optionee. If the Board makes an Option transferable, such Option shall
contain additional terms and conditions as the Board deems appropriate.

         10. Adjustments Upon Changes in Capitalization, Dissolution, Merger or
Asset Sale.

                  (a) Changes in Capitalization. Subject to any required action
by the stockholders of the Company, the number of Shares covered by each
outstanding Option, the number of Shares which have been authorized for issuance
under the Plan but as to which no Options have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option, as well
as the price per Share covered by each such outstanding Option, and the number
of Shares issuable pursuant to the automatic grant provisions of Section 4
hereof shall be proportionately adjusted for any increase or decrease in the
number of issued Shares resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of issued Shares effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into 




                                      -6-
<PAGE>   7
shares of stock of any class, shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of Shares subject to an
Option.

                  (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall terminate immediately prior to the
consummation of such proposed action.

                  (c) Merger or Asset Sale. In the event of a merger of the
Company with or into another corporation or the sale of substantially all of the
assets of the Company, outstanding Options may be assumed or equivalent options
may be substituted by the successor corporation or a Parent or Subsidiary
thereof (the "Successor Corporation"). If an Option is assumed or substituted
for, the Option or equivalent option shall continue to be exercisable as
provided in Section 4 hereof for so long as the Optionee serves as a Director or
a director of the Successor Corporation. Following such assumption or
substitution, if the Optionee's status as a Director or director of the
Successor Corporation, as applicable, is terminated other than upon a voluntary
resignation by the Optionee, the Option or option shall become fully
exercisable, including as to Shares for which it would not otherwise be
exercisable. Thereafter, the Option or option shall remain exercisable in
accordance with Sections 8(b) through (d) above.

         If the Successor Corporation does not assume an outstanding Option or
substitute for it an equivalent option, the Option shall become fully vested and
exercisable, including as to Shares for which it would not otherwise be
exercisable. In such event the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

         For the purposes of this Section 10(c), an Option shall be considered
assumed if, following the merger or sale of assets, the Option confers the right
to purchase or receive, for each Share of Optioned Stock subject to the Option
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares).
If such consideration received in the merger or sale of assets is not solely
common stock of the successor corporation or its Parent, the Administrator may,
with the consent of the successor corporation, provide for the consideration to
be received upon the exercise of the Option, for each Share of Optioned Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

         11.      Amendment and Termination of the Plan.

                  (a) Amendment and Termination. The Board may at any time
amend, alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without 




                                      -7-
<PAGE>   8
his or her consent. In addition, to the extent necessary and desirable to comply
with any applicable law, regulation or stock exchange rule, the Company shall
obtain stockholder approval of any Plan amendment in such a manner and to such a
degree as required.

                  (b) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.

         12. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date determined in accordance with Section 4 hereof.

         13. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated there
under, state securities laws, and the requirements of any stock exchange upon
which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

                  As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares, if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

                  Inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority shall not have been
obtained.

         14. Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

         15. Option Agreement. Options shall be evidenced by written option
agreements in such form as the Board shall approve.

         16. Stockholder Approval. Continuance of the Plan shall be subject to
approval by the stockholders of the Company at or prior to the first annual
meeting of stockholders held subsequent to the granting of an Option hereunder.
Such stockholder approval shall be obtained in the degree and manner required
under applicable state and federal law and any stock exchange rules.

                 REPRESENTATIONS AND WARRANTIES OF THE INVESTORS

         Each Investor hereby represents and warrants to the Company with
respect to its purchase of the Shares as follows:

         4.l      INVESTMENT REPRESENTATIONS AND COVENANTS OF THE INVESTORS.

                  (a) This Agreement is made by the Company with each Investor
in reliance upon such Investor's representations and covenants made in this
Section 4, which by its execution of this Agreement the Investor hereby
confirms. Each Investor represents that the Shares to be received will be
acquired for investment for its own account, not as a nominee or agent, and not
with a view to the sale or distribution of any part thereof, and that it has no
present intention of selling, granting any participation in or otherwise
distributing the same. Each Investor further represents that it does not have
any contract, undertaking, agreement or arrangement with any person (other than
certain partners and employees of Investor and its affiliates) to sell, transfer
or grant participations to such person or to any third person, with respect to
any of the Shares or any Common Stock acquired on conversion thereof.

                  (b) Each Investor understands and acknowledges that the
offering of the Shares pursuant to this Agreement will not, and any issuance of
Common Stock on conversion thereof may not, be registered under the Securities
Act on the ground that the sale provided for in this Agreement and the issuance
of securities hereunder is exempt pursuant to section 4(2) of the Securities
Act, and that the Company's reliance on such exemption is predicated on the
Investors' representations set forth herein.

                  (c) Each Investor covenants that in no event will it make any
disposition of any of the Shares, or any Common Stock acquired upon the
conversion thereof, except in accordance with the Stockholders' Agreement as
amended by Amendment No. 1 and the Company's Bylaws. Each Investor further
covenants that it will not make any sale, transfer or other disposition of the
Shares or the Common Stock issuable upon conversion thereof in violation of the
Securities Act, the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), or the rules of the Securities and Exchange Commission (the "Commission")
promulgated thereunder.

                  (d) Each Investor represents that it is capable of evaluating
the merits and risks of its prospective investment in the Company, and has the
ability to bear the economic risks of the investment.



                                      -13-
<PAGE>   19
                  (e) Each Investor acknowledges and understands that the
Shares, and any Common Stock acquired upon the conversion thereof, must be held
indefinitely unless it is subsequently registered under the Securities Act or an
exemption from such registration is available, and that, except as otherwise
provided in the Stockholders' Agreement, the Company is under no obligation to
register either the Shares or Common Stock.

                  (f) Each Investor acknowledges that it has reviewed a copy of
Rule 144 promulgated under the Securities Act, which permits limited public
resales of securities acquired in a non public offering, subject to the
satisfaction of certain conditions. Each Investor understands that before the
Shares, or any Common Stock issued upon conversion thereof, may be sold under
Rule 144, the following conditions must be fulfilled: (i) certain public
information about the Company must be available, (ii) the sale must occur at
least two years after the Investor purchased and paid for the Shares, (iii) the
sale must be made in a broker's transaction and (iv) the number of Shares sold
must not exceed certain volume limitations. Each Investor understands that the
current information referred to above is not now available and there can be no
assurances that the Company will make such information available in the future.

                  (g) Each Investor acknowledges that in the event the
applicable requirements of Rule 144 are not met, registration under the
Securities Act, compliance with the Commission's Regulation A or another
exemption from registration will be required for any disposition of its stock.
Each Investor understands that although Rule 144 is not exclusive, the
Commission has expressed its opinion that persons proposing to sell restricted
securities received in a private offering other than in a registered offering or
pursuant to Rule 144 will have a substantial burden of proof in establishing
that an exemption from registration is available for such offers or sales and
that such persons and the brokers who participate in the transactions do so at
their own risk.

                  (h) Each Investor represents that such Investor is an
"accredited investor" as defined in Rule 501 of Regulation D promulgated under
the Securities Act.

         4.2 NO PUBLIC MARKET.

         Investor understands that no public market now exists for any of the
securities issued by the Company and that there can be no assurance that a
public market will ever exist for the Shares.

         4.3      RECEIPT OF INFORMATION.   

         Investor has received and reviewed this Agreement and all exhibits
hereto. Investor and its counsel have had access to and an opportunity to review
all docu-



                                      -14-

ments and other materials requested of the Company; Investor and its counsel
have been given an opportunity to ask any and all questions of, and receive
answers from, the Company concerning the terms and conditions of the offering
and to obtain all information it or they believe necessary or appropriate to
evaluate the suitability of an investment in the Company.

         4.4 AUTHORIZATION.

         This Agreement, when executed and delivered by the Investor, will
constitute a valid and legally binding obligation of the Investor, enforceable
in accordance with its terms, subject to laws of general application relating to
bankruptcy, insolvency and the relief of debtors and rules of law governing
specific performance, injunctive relief or other equitable remedies.

         4.5 BROKERS OR FINDERS.

         The Company has not, and will not, incur, directly or indirectly, as a
result of any action taken by any Investor any liability for brokerage or
finders' fees or agents commissions or any similar charges in connection with
this Agreement.

         4.6 TAX ADVISORS.

         Each Investor has reviewed with its own tax advisors the federal,
state, local and foreign tax consequences of this investment, where applicable,
and the transactions contemplated by this Agreement. Each Investor is relying
solely on such advisors and not on any statements or representations of the
Company or any of its agents with respect to such tax consequences and
understands that it (and not the Company) shall be responsible for the
Investor's own tax liability that may arise as a result of this investment or
the transactions contemplated by this Agreement.

Ltd. Therefore Synon Ltd. will need to obtain the consent of the other parties
to those contracts to the liquidation of Synon Ltd. and/or the assignment of the
contracts to the DRC. See the letter written to the Synon Ltd. Board of
Directors by Kim Nicholson of Baileys Shaw and Gillett dated November 30, 1990.
The liquidation of Synon Ltd. would also result in the release of the source
code of two of Synon's principal products (Synon 1 and Synon 2) to several U.K.
distributors pursuant to source code agreements entered into between Synon Ltd.
and such distributors. (The release of the source code to the distributors would
be for maintenance and enhancement of the source code only and all intellectual
property rights would remain with Synon Ltd.) Therefore, the consent of such
distributors and the source code escrow agent would also be required in the
event Synon Ltd. is liquidated.

         2. Many of the lease agreements entered into by Synon Ltd. require the
consent of the other party thereto for a change in control. The change in
control provisions may have been triggered by the share exchange effected in
December 1990, and no consents to such share exchange were obtained. See the
letter to Michael Sheridan from Tom Shaw of Baileys, Shaw and Gillett dated
November 30, 1990.

         3. The Company has a multi-currency overdraft facility (the "Facility")
with Midland Bank Plc. The Company has defaulted in certain respects under the
Facility. Midland Bank Plc has agreed to renew the Facility up to 3,000,000
pending completion of the Series D Preferred Stock financing.

Dear Rich:

         I am pleased to confirm my verbal offer for you to join Synon
Corporation ("Synon") as Chief Executive Officer and President.  This letter
will review the terms of your employment offer with Synon as follows:


         1.      You will serve in the position of Chief Executive Officer and
                 President of Synon, reporting to the Board of Directors, and
                 assuming and discharging such responsibilities as are
                 commensurate with such office and position.  You shall comply
                 with and be bound by Synon's operating policies, procedures
                 and practices.  It is anticipated that the effective date of
                 your employment will be on or about October 1, 1992.

         2.      During the term of your employment with Synon, you shall
                 devote your full time, skill and attention to your duties and
                 responsibilities, and shall perform them faithfully,
                 diligently and competently, and you shall use your best
                 efforts to further the business of Synon and its affiliates.
                 Your employment with Synon is for an unspecified duration that
                 constitutes at-will employment and either Synon or you can
                 terminate this relationship at any time.

         3.      In consideration of your services, you will be paid a salary
                 of $18,750 per month (annualized rate of $225,000), payable
                 semi-monthly in accordance with Synon's standard payroll
                 practices.  As with other officers of Synon, this base
                 compensation will be reviewed annually by the Board of
                 Directors.

         4.      In addition to your base compensation, the Board of Directors
                 shall adopt an executive bonus program under which you shall
                 be entitled to earn incentive compensation based upon the
                 satisfaction of certain performance goals.  It is contemplated
                 that these performance objectives will be determined by the
                 Board of Directors in consultation with you, and will concern
                 such matters as pre-tax profitability and return on
                 shareholders' equity of Synon.  The bonus will be targeted at
                 $100,000 annually and guaranteed for the first nine months of
                 employment at Synon.  It is further anticipated that
                 additional incentive compensation will be provided for
                 overachievement as determined by the Board of Directors in
                 consultation with you.

         5.      You will be entitled to receive Synon's fringe benefits made
                 available to other employees and officers to the full extent
                 of your eligibility therefor.  You shall be entitled to four
                 weeks of paid vacation per year (which shall be consistent
                 with Synon's vacation policy and which shall not accrue in
                 excess of four weeks per year).  During your employment, you
                 shall be permitted, to the extent eligible, to participate in
                 any group life, hospitalization or disability insurance plan,
                 health program, or similar benefit plan of Synon that may be
                 available to other comparable employees generally on the same
                 terms as such other employees.  Participation in any such plan
                 shall be consistent with your rate of compensation to the
                 extent that compensation is a determinative factor with
                 respect to coverage under any such plan.  Business expenses
                 incurred by you will be reimbursed according to Synon's
                 expense reimbursement policy.  In addition, you will be
                 reimbursed for expenses associated with your relocation to the
                 San Francisco Bay area; such as, temporary apartment rental,
                 closing costs for buying and selling a home, and moving your
                 household goods.

         6.      Upon your acceptance of employment, you will be granted a
                 non-statutory option to purchase 500,000 shares of Synon
                 common Stock under Synon's 1990 Stock Option Plan.  The option
                 price shall be $1.43 and the option shall have a term of ten
                 years.  The Option Agreement will provide that your right to
                 exercise the option will vest cumulatively over a period of
                 five years, vesting at 20% on the first anniversary of the
                 effective date of your employment and thereafter on a monthly
                 basis (1.6667% per month).

                 In addition, (i) upon any Change of Control of Synon
                 Corporation (as defined herein), 50% of the shares remaining
                 unvested will vest automatically and any of the then remaining
                 unvested options will vest monthly in equal increments over
                 the balance of the five year vesting period and (ii) if your
                 employment is involuntarily terminated or Constructively
                 Terminated (as defined herein) within twelve (12) months after
                 a Change of Control (it being the intention that you will
                 agree to remain employed for at least one year following a
                 "Change of Control"), then your option shall be accelerated to
                 become immediately exercisable for 100% of the total number of
                 unvested shares subject thereto.

                 In addition, upon initial public offering by Synon, 20% of the
                 shares remaining unvested will vest automatically and any of
                 the then remaining unvested options will vest monthly in equal
                 increments over the balance of the five year vesting period.

         7.      In addition, if your employment is involuntarily terminated
                 other than for "cause" (as defined herein), then you shall
                 receive one year's base salary plus annual targeted bonus
                 incentive as severance.

                 For purposes of the foregoing, termination "for cause" shall
                 mean (i) the willful failure by you substantially to perform
                 your material duties after a written demand for substantial
                 performance is delivered to you by the Board of Directors
                 which specifically identifies the manner in which the Board of
                 Directors believes that you have not substantially performed
                 your duties, (ii) the failure (in a material respect) by you
                 to follow a written, lawful order or directive from the Board
                 of Directors of Synon, (iii) the conviction of you of any
                 crime involving the property or business of Synon or its
                 affiliates or (iv) any act of moral turpitude in connection
                 with the performance of your duties hereunder.

         8.      For purposes of the foregoing, a "Change of Control of Synon"
                 shall be deemed to have occurred if (i) Synon sells or
                 otherwise disposes of all or substantially all of its assets;
                 (ii) there is a merger or consolidation of Synon with any
                 other corporation or corporations, provided that the
                 shareholders or Synon, as a group, do not hold, immediately
                 after such event, at least 50% of the voting power of the
                 surviving or successor corporation; (iii) any person or
                 entity, including any "person" as such term is used in Section
                 13(d)(3) of the Securities Exchange Act of 1934, as amended
                 (the "Exchange Act"), becomes the "beneficial owner" (as
                 defined in the Exchange Act) of Common Stock of Synon
                 representing 50% or more of the combined voting power of the
                 voting securities of Synon (exclusive of persons who are now
                 officers or directors of Synon).

                 For purposes of the foregoing, your employment with Synon
                 shall be deemed to have been "Constructively Terminated" if
                 there shall occur (i) a material reduction in salary or
                 benefit (taken as a whole), (ii) a material change in
                 responsibility, or (iii) a requirement to relocate, except for
                 office relocations that would not increase your one-way
                 commute distance by more than 5O miles.

         9.      Upon acceptance of this offer, you will be required to sign
                 Synon's standard employee proprietary information agreement.

         and other software products, application software, templates and data
         models (together "Inventions").  You acknowledge that any Inventions
         you develop or have developed in connection with your employment by

         of the Company, and you agree not to assert any individual ownership
         rights with respect to those Inventions.  Upon request by the Company
         and at the Company's consent, you will sign such further agreements
         and assignments as may be necessary to transfer to the Company or

         those documents on your behalf.  Your obligations under this paragraph
         do not apply to any Invention for which no equipment, supplies,
         facility or trade secret of the Company or a client of the Company was
         used and which was developed entirely on your own time, unless (a) the
         Invention relates (i) to the business of the Company or (ii) to the
         Company's actual or demonstratable anticipated research or development
         or (b) the Invention results from any work performed by you for the
         Company.

         Attached hereto, as Exhibit A, is a list describing all inventions,
         original works of authorship, developments, improvements, and trade
         secrets (collectively "Prior Inventions"), that belong to you, that

         development, and that are not assigned to the Company hereunder; or,
         if no such list is attached, you represent that there are no such
         Prior Inventions.  If in the course of your employment with the
         Company, you incorporate into a Company product, process or

Dear Duncan:

While we recognize your long service to Synon, we determined a change in the
management of Synon's European operations was necessary.  As we discussed, your
employment with Synon therefore terminated effective December 31, 1997.

STATUTORY SEVERANCE CONSIDERATION: You have or will receive, as soon as
practical following acceptance of this separation letter agreement, all
statutory payments owed to you including the following: 

          The sum of pounds 15,960.23 representing 5.82 weeks pay in lieu of 
                 notice based on current salary plus pension benefits and 
                 automobile allowance.
         The sum of pounds 2,742.31 representing 5 days of 1996 holiday accrued
                 but unused consistent with Synon Europe Ltd. unused holiday
                 carryover policy.
         The sum of pounds 1,842.83 representing 3.36 days of 1997 holiday
                 accrued through the notice period.
         The sum of pounds 116,000.00 representing salary for one year
                 consistent with the terms of your employment letter agreement
                 with Synon Corp. dated February 7, 1992.
         The sum of pounds 13,337.96 representing a bonus based on 1996 Synon
                 Corp. financial performance and an additional discretionary 
                 bonus.
         Less the sum of pounds 11,883.33 which has already been paid to you
                 through payroll continuation in January 1997.
Synon agrees to pay you any portion of these amounts ex gratia to the extent
allowable under British law.

Outstanding expenses will be reimbursed to you as soon as approved and
processed.  You will turn over to Synon all company property including keys,
credit cards, hardware, software and any confidential material such as lists of
employees, clients, etc.  In addition, you agree to execute whatever documents
are necessary to effect your resignation as officer or director of any of the
group companies and to make the relevant filings at local companies registries.
We have directed Mr. Victor Bhalla to prepare customary officer and director
indemnification agreements to indemnify you on behalf of Synon and it
associated companies against actions potentially taken against you by virtue of
your office while employed by Synon.  Please contact Mr. Bhalla to arrange
appropriate resignations of your officer and director positions and to complete
the indemnification agreements.

periods ceased at the end of your notice period of 5.82 weeks following

that date, you have 220,000 shares of options vested and exercisable.  However,
without any obligation to do so, but in consideration of your prior service, to
accomplish the smooth transition desirable to all parties and in consideration
of the Restrictive Covenants and the Release below, Synon offers to extend your
Stock Option exercise period through November 30, 1997, for those options
vested.  After that date, your options will expire.

         indirectly, make, publish or otherwise communicate to any third party
         any disparaging or derogatory statements concerning Synon or its
         management which, in Synon management's view acting reasonably, would
         have a material adverse affect on Synon's business or reputation.
         Synon, likewise undertakes that it will not, whether directly or
         indirectly, make, publish or otherwise communicate to any third party

         acting reasonably, would have a material adverse affect on you or your
         reputation.  This undertaking for Synon will extend to it officers,
         directors and employees.

         2.      You will not, during the period ending November 30, 1997,
         either for your own account or for any person, firm or company
         directly or indirectly employ, solicit, or endeavor to solicit any
         person who was an employee of Synon or any of its associated companies
         as of your effective termination date, and with whom you had dealings
         while you were employed by Synon, without the written permission of
         Synon management acting reasonably.

         3.      You will not, during the period ending November 30, 1997, be
         engaged or involved either directly or indirectly, with any business
         which, in the opinion of Synon management acting reasonably, competes
         directly with the business of Synon and its associated companies
         without the written permission from Synon.

If you violate covenant 1 above, 25% of your vested stock options will be
canceled and no longer available for exercise by you.

written notice of its knowledge of the violation.  You have up to 30 days to

liability regarding your employment.  You understand these provisions are

Dear Mr. Wilde:

         This letter will confirm your terms of employment with Synon
Corporation ("Synon"), a Delaware corporation, as follows:

         1.      You will serve in the position of Vice President and Chief
Financial Officer of Synon, reporting to the Chief Executive Officer, and
assuming and discharging such responsibilities as are commensurate with such
office and position. It is anticipated that the effective date of your
employment will be on or about April 15, 1991.

         2.      In consideration of your services, you will be paid a salary
of $12,500 per month (annualized rate of $150,000), payable semi- monthly in
accordance with Synon's standard payroll practices. As with other officers of
Synon, this base compensation will be reviewed annually by the Board of
Directors.

         3.      In addition to your base compensation, the Board of Directors
shall adopt an executive bonus program under which you shall be entitled to
receive an annual bonus of $50,000, based upon the satisfaction of certain
performance goals.  It is contemplated that these performance objectives will
be determined by the Board of Directors in consultation with you, and will
concern such matters as pre-tax profitability or return on shareholders' equity
of Synon.  This bonus shall be $31,250 for the year ending December 31, 1991.

         4.      You intend to sell your residence located in Arizona. Synon
will make you a loan of up to $200,000, at such time as you request during your
employment, for the purpose of assisting your purchase of a new home near your
place of employment with Synon. The loan will have a term of five years and
will be interest-free.  However, the loan may be prepaid at any time without
penalty. The loan shall be forgiven over five years at a rate of $40,000 per
year from your start date.  You will be responsible for all taxes owed as a
result of the forgiveness of the loan and any imputed interest thereon. The
balance of this loan will be due upon any voluntary termination; upon
Constructive Termination (defined herein) the balance of this loan shall be
payable and due within 12 months of such termination.
<PAGE>   2
                                      -2-


         When you relocate your residency to the San Francisco area, Synon will
reimburse you for all reasonable moving expenses, not to exceed $50,000. Synon
will be responsible for all taxes owed as a result of this reimbursement.

         5.      You will be entitled to receive Synon's fringe benefits made
available to other employees and officers to the full extent of your
eligibility therefor. Business expenses incurred by you will be reimbursed
according to Synon's expense reimbursement policy.

         6.      In the event that your employment with Synon is (i)
involuntarily terminated during the first 36 months after commencement of
employment, or (ii) involuntarily terminated or Constructively Terminated
within six (6) months following a Change in Control (as defined herein), you
shall be entitled to a severance payment of $150,000, payable in 12 equal
monthly installments, plus group health, disability, life and other insurance
coverage for one year (or comparable compensation therefor).

         7.      Upon your acceptance of employment, you will be granted an
option to purchase 150,000 shares of Synon Common Stock under Synon's Employee
Stock Option Plan subject to approval of the Board of Directors. (It being
understood that the number of shares has been calculated based upon the
Company's anticipated capitalization following the Series D Preferred
financing.) Under the plan, the option price shall be equal to the fair market
value of the Common Stock on the date of grant (as determined by the Board of
Directors) and shall have a term of ten years. The Option Agreement will
provide that you shall have the right to exercise the option over a period of
five years, vesting at 20% on each anniversary of the effective date of your
employment.

         In addition, in the event your employment is involuntarily terminated
or Constructively Terminated within six (6) months after a Change of Control
(as defined herein); the option shall become immediately exercisable for the
full number of shares subject thereto.

         8.      For purposes of the foregoing, a "Change of Control of Synon"
shall be deemed to have occurred if (i) Synon sells or otherwise disposes of
all or substantially all of its assets; (ii) there is a merger or consolidation
of Synon with any other corporation or corporations, provided that the
shareholders of Synon, as a group, do not hold, immediately after such event,
at least 50% of the voting power of the surviving or successor
<PAGE>   3
                                      -3-


corporation; (iii) any person or entity, including any "person" as such term is
used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), becomes the "beneficial owner" (as defined in the
Exchange Act), of Common Stock of Synon representing 50% or more of the
combined voting power of the voting securities of Synon (exclusive of persons
who are now officers or directors of Synon).

         9.      For purposes of the foregoing, your employment with Synon
shall be deemed to have been "Constructively Terminated" if there shall occur
(i) a material reduction in salary or benefit (taken as a whole), (ii) a
material change in responsibility, or (iii) a requirement to relocate, except
for office relocations that would not increase your one-way commute distance by
more than fifty (50) miles.

         10.     This agreement shall be governed by the laws of the State of
California.

         Please execute the enclosed copy of this letter, whereupon it shall
become a binding agreement.  Synon and you shall undertake to promptly prepare
and execute all of the documents and agreements as are reasonably necessary to
carry out the intentions expressed herein, including the standard Synon
employment agreement.  This agreement shall inure to the benefit of and shall
be binding upon the parties hereto and their respective heirs, personal
representatives, successors and assigns, if any.

Dear Paul:

         Reference is made to that certain employment offer letter agreement
dated as of March 27, 1991 between Synon, Inc. (the "Company") and you (the
"Employment Letter").  The parties, desiring to amend the Employment Letter,
hereby agree to add the following:

         During the course of your employment, you may create, develop or
         improve processes, designs, techniques, original works of authorship,
         concepts, trade secrets or other intellectual property, including
         without limitation, computer software such as application development
         and other software products, application software, templates and data
         models (together "Inventions").  You acknowledge that any Inventions
         you develop or have developed in connection with your employment by
         the Company are works for hire and are owned by the Company or clients
         of the Company, and you agree not to assert any individual ownership
         rights with respect to those Inventions.  Upon request by the Company
         and at the Company's consent, you will sign such further agreements
         and assignments as may be necessary to transfer to the Company or
         clients of the Company any rights you may have in those Inventions and
         to register those rights in the name of the Company or client of the
         Company, and you appoint the Company as your attorney-in-fact to sign
         those documents on your behalf.  Your obligations under this paragraph
         do not apply to any Invention for which no equipment, supplies,
         facility or trade secret of the Company or a client of the Company was
         used and which was developed entirely on your own time, unless (a) the
         Invention relates (i) to the business of the Company or (ii) to the
         Company's actual or demonstratable anticipated research or development
         or (b) the Invention results from any work performed by you for the
         Company.

         Attached hereto, as Exhibit A, is a list describing all inventions,
         original works of authorship, developments, improvements, and trade
         secrets (collectively "Prior Inventions"), that belong to you, that
         relate to the Company's business, products or research and
         development, and that are not assigned to the Company hereunder; or,
         if no such list is attached, you represent that there are no such
         Prior Inventions.  If in the course of your employment with the
         Company, you incorporate into a Company product, process or
<PAGE>   7

         interest, the Company is hereby granted and will have a nonexclusive,
         royalty-free, irrevocable, perpetual, worldwide license, with the
         right to grant sublicenses, to make, have made, modify, use and sell
         such Prior Invention as part of or in connection with such product,
         process or machine.

         RE:  AMENDMENT TO EMPLOYMENT LETTER

Dear Mr. Wilde:

         This letter is to amend the terms of your employment with Synon
Corporation ("Synon") as set forth in your employment letter dated March 27,
1991 (the "Employment Letter").  This amendment shall conform the terms of the
Employment Letter to the agreement between Synon and you and to the terms of
the Promissory Note and Security Agreement, each dated September 24, 1992,
between Synon and you.  The Employment Letter shall be amended as follows:

         1.       The first paragraph of Section 4 is amended to read in its
                  entirety as follows (changes underlined):

                 "You intend to sell your residence located in Arizona.  Synon
                 will make you a loan of $200,000, at such time as you request
                 during your employment, for the purpose of assisting your
                 purchase of a new home near your place of employment with
                 Synon.  The loan will have a term of five years and will bear
                 interest at 8% per annum, payable at least annually, subject
                 to your continuing status as an employee or consultant of the
                 Company. $3,333.33 of indebtedness (1/60 of the principal)
                 shall be forgiven at the end of each one-month period
                 following April 15, 1991 (your employment start date)
                 resulting in total forgiveness of the loan at the end of five
                 (5) years from your employment start date. You will be
                 responsible for all taxes owed as a result of the forgiveness
                 of the loan and any imputed interest thereon.  The balance of
                 this loan will be due upon any voluntary termination; if you
                 are involuntarily terminated without cause or Constructively
                 Terminated (as defined herein) the balance of this loan shall
                 be payable and due within 12 months of such termination.
                 Notwithstanding the foregoing, if you voluntarily terminate
                 your employment with Synon during calendar year 1993, other
                 than due to your being Constructively Terminated, the loan
                 will be forgiven to the extent of (i) $40,000, if such
                 termination is prior to April 15, 1993, or (ii) $80,000, if
                 such termination is between April 15, 1993 and December 31,
                 1993. In
<PAGE>   9
                 the event you are involuntarily terminated without cause or
                 Constructively Terminated at any time while the loan remains
                 outstanding, the loan will be forgiven to the extent of the
                 ratable portion described above plus an additional $40,000."

         2.      A new paragraph shall be added to Section 4 as follows:

                 "For each year in which you are required to pay to Synon
                 interest on the loan discussed above, Synon will pay to you an
                 additional annual bonus equal to such interest payment."

         3.      Section 6 is amended in its entirety to read as follows
                 (changes underlined):

                 "In the event that your employment with Synon is (i)
                 involuntarily terminated during the first 36 months after
                 commencement of employment, or (ii) involuntarily terminated
                 or Constructively Terminated within six (6) months following a
                 Change in Control (as defined herein), you shall be entitled
                 to a severance payment equal to one year of your then current
                 salary, payable in 12 equal monthly installments, plus group
                 health, disability, life and other insurance coverage for one
                 year (or comparable compensation therefor)."

         Except as otherwise provided herein, the terms of your employment
shall continue to be governed by the terms contained in the Employment Letter,

         Please execute the enclosed copy of this letter whereupon it shall
become a binding amendment to the Employment Letter.  Synon and you shall
undertake to promptly prepare and execute all of the documents and agreements
as are reasonably necessary to carry out the intentions expressed herein.  This
amendment shall inure to the benefit of and shall be binding upon the parties
hereto and their respective heirs, personal representatives, successors and
assigns, if any.

                                        Very truly yours,

                                        SYNON CORPORATION

       your best efforts to further the business of Synon.  Your employment
       with Synon is for an unspecified duration that constitutes at-will
       employment and either Synon or you can terminate this relationship at

5.       You will be entitled to receive Synon's fringe benefits made available
         to other employees and officers to the full extent of your eligibility
         therefore.  You shall be entitled to three weeks of paid vacation per
         year (which shall not accrue in excess of three weeks per year).
         During your employment, you shall be permitted, to the extent
         eligible, to participate in any group life, hospitalization or
         disability insurance plan, health program, or similar benefit plan of

         under any such plan.  Business expenses, incurred by you will be
         reimbursed according to Synon's expense reimbursement policy.

6.       Upon your acceptance of employment, you will be granted a
         non-statutory option to purchase 200,000 shares of Synon Common Stock
         under Synon's 1990 Stock Option Plan subject to approval of the Board
         of Directors.  The option price shall be $1.80 and the option shall
         have a term of ten years.  The Option Agreement will provide that your
         right to exercise the option will vest cumulatively over a period of
         four years, vesting at 25% on the first anniversary of the effective
         date of your employment and thereafter on a monthly basis (2.0833% per

         In addition, (i) upon any Change of Control of Synon Corporation (as
         defined herein) or initial public offering by Synon Corporation,
         whichever occurs first, any of the 200,000 shares remaining unvested,
         up to a maximum of 50,000 shares, will vest automatically and any of
         the then remaining unvested options will vest monthly in equal
         increments over the balance of the original vesting period and (ii) if
         your employment is involuntarily terminated or Constructively
         Terminated (as defined herein) within twelve (12) months after a
         Change of Control (it being the intention that you will agree to
         remain employed for at least one year following a "Change of
         Control"), then your option shall be accelerated to become immediately
         exercisable for 50% of the total number of unvested shares subject
         thereto.

7.       In addition, if your employment is involuntarily terminated other than
         for "cause" (as defined herein) then (i) if such termination occurs
         prior to Change of Control (as defined herein) you shall receive six
         months salary as severance, or, (ii) if termination occurs
         involuntarily or "constructively" (as defined herein), other than for
         cause, within one year following Change of Control then you shall
         receive 1 year's salary as severance.

8.       For purposes of the foregoing, termination "for cause" shall mean (i)
         the willful failure by you substantially to perform your material
         duties after a written demand for substantial performance is delivered
         to you by the Chief Executive which specifically identifies the manner
         in which he believes that you have not substantially performed your
         duties; (ii) the failure (in a material respect) by you to follow a
         written, lawful order or directive from the Chief Executive; (iii) the
         conviction of you of any crime involving the property or business of
         Synon or its affiliates; or (iv) any act of moral




                                                                               2
<PAGE>   3
         turpitude in connection with the performance of your duties hereunder

9.       For purposes of the foregoing, a "Change of Control of Synon" shall be
         deemed to have occurred if (i) Synon sells or otherwise disposes of
         all or substantially all of its assets; (ii) there is a merger or
         consolidation of Synon with any other corporation or corporations,
         provided that the shareholders of Synon, as a group, do not hold,
         immediately after such event, at least 50% of the voting power of the
         surviving  or successor corporation; (iii) any person or entity,
         including any "person" as such term is used in Section 13(d)(3) of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act")
         becomes the "beneficial owner" (as defined in the Exchange Act) of
         Common Stock of Synon representing 50% or more of the combined voting
         power of the voting securities of Synon (exclusive of persons who are
         now officers of directors of Synon).

10.      For purposes of the foregoing, your employment with Synon shall be
         deemed to have been "Constructively Terminated" if there shall occur
         (i) a material reduction in salary or benefit (taken as a whole); or
         (ii) a material change in responsibility, or (iii) a requirement to
         relocate, except for office relocations that would not increase your
         one-way commute by more than 50 miles.

11.      Upon acceptance of this offer, you will be required to sign Synon's
         standard employee proprietary information agreement.

Please acknowledge acceptance of this offer by signing and returning the

                          Incorporation or by using a Conversion Price for each
                          respective series of Preferred Stock other than as
                          set out in the current version of Section 5(d) of the
                          said Fourth Article for each such series of Preferred
                          Stock, or

                 c.       the Company or Synon Corporation is in material
                          breach of this Employment Agreement;

                 then the said rate of Commission shall not be so reduced.  The
                 references to "Preferred Stock", "Common Stock" and
                 "Conversion Price" in this clause 2.5ii shall have the
                 meanings given to them in the current version of Section 5 of
                 the Fourth Article of Synon Corporation's Certificate of
                 Incorporation.

2.6      All payments to be made to you hereunder shall be paid in British
         pounds sterling and in respect of the Commission any fees received by
         Synon Corporation or the Company and its subsidiaries and associated
         companies on which the same is payable shall be converted to sterling
         by reference to the spot rate on the London Foreign Exchange Market at
         about 11am on the first day of the calendar mouth in which the payment
         is made.

2.7      The Company shall maintain and shall procure that its subsidiary and
         associated companies maintain complete and accurate records of such
         information as may be reasonably necessary to accurately calculate all
         payments due to you as Commission and shall on reasonable notice make
         the same available to you for inspection (and if requested copying) by
         you or your representative no more frequently than once in any six (6)
         month period.

2.8      If any Commission payable to you hereunder is not paid by the due date
         for payment then such sum shall bear interest at the rate of two per
         cent (2%) above the base lending rate from time to time of Barclays
         Bank plc from the date such sum falls due for payment until the date
         of actual payment compound twice yearly at six (6) month intervals.

2.9      In the event of any dispute arising between us as to the amount of any
         Commission payable or paid hereunder the matter shall be referred to
         an independent third party at your request for it to certify the
         amount properly due and payable pursuant to the terms of this
         Agreement.  Such independent third party shall be such person or
         entity as you and the Company shall agree and failing agreement shall
         be appointed by the President of the Institute of Chartered
         Accountants at your request.  Such independent third party shall act
         as expert and not as arbitrator hereunder and his decision shall be
         final and binding on the parties hereto save in the case of fraud or
         manifest error.  The costs of such expert shall be borne as to fifty
         percent (50%) by the Company and 50% by you unless such expert shall
         decide that one party has acted unreasonably in which case he shall
         have discretion as to costs.

2.10     The Company will promptly refund to you all reasonable travelling,
         hotel and other expenses properly incurred by you in performance of
         your duties under this Agreement.  When travelling by air during the
         performance of your duties under this Agreement you are entitled to
         purchase a business class ticket or its equivalent, and the Company
         will refund to you the cost of such ticket.

2.11     You are not entitled to any pension from the Company.  A contracting
         out certificate under the Social Security Act 1975 is not in force in
         respect of the employment to which this letter refers.

3.       Salary during illness.

         If you are absent through illness or accident for more than a total of
         six months in any consecutive period of twelve months your basic
         salary may be reduced during any period in excess of the six month
         period to one half of that to which you would otherwise be entitled.
         Included within such salary shall be any amount to which you are
         entitled as Statutory Sick Pay. The Company will deduct from your
         salary any income benefit which you are entitled to claim in
         consequence of any sickness or accident under the National Insurance
         scheme in force at the time



                                  Page 3 of 6
<PAGE>   4
         including Statutory Sick Pay and social security sickness benefit.
         For the purpose of calculating your entitlement to statutory Sick Pay
         "qualifying days" are Monday to Friday.

4.       Hours of work

4.1      You will conform to such hours of work as may from time to time be
         reasonably required of you and you will not be entitled to receive any
         additional remuneration for work outside your normal hours.

4.2      At the time of writing, the Company operates flexible working hours,
         whereby you are required to work 37.5 hours during each working week
         (less 7.5 hours for each usual public and statutory holiday) and are
         required to be at work between the hours of 10.00am and 4.00pm on each
         working day.

5.       Holidays

5.1      You will be entitled to the usual public and statutory holidays, and
         in addition to twenty-two working days holiday in each full calendar
         year of employment, to be taken at times as may be approved by the
         Company.

5.2      During the years in which your employment commences and terminates,
         you will be entitled to holiday in direct proportion to your length of
         service during that year, calculated as:

                 No of days service / 365 X 22, rounded to the nearest whole day

5.3      On termination of your employment with the Company for any reason your
         final basic salary payment shall be increased or decreased by:

                (Holiday entitlement - Holiday days taken) X Annual salary / 260

5.4      If during any calendar year you do not take all the holiday to which
         you are entitled, you shall not carry forward any holiday entitlement,
         and you shall not be entitled to any additional remuneration in
         respect of the unused entitlement.

6.       Term and termination.

6.1      Your employment with the Company commenced on 1st January 1992, and no
         previous employment counts as part of your continuous period of
         employment with the Company.

6.2      Unless previously terminated under other provisions of this clause
         your employment with the Company will continue until terminated by
         either party giving one month's written notice to the other.

6.4      In the event of your performance proving unsatisfactory, the Company
         may give you written notification of this, detailing the specific
         reasons.  The Company may then subsequently terminate your employment
         if in its opinion there has been insufficient improvement in your
         performance.  Notice of termination will be given to you not sooner
         than one month nor later that three months after the date of the
         original notification.  The period for such notice shall be one month.

6.5      Your employment with the Company shall in any event (unless otherwise
         agreed in writing) terminate on the date of your sixtieth birthday.

6.6      The Company may terminate your employment with the Company by notice
         in writing immediately:

         a.      If you act so as to bring yourself or the Company into
                 disrepute, or if you are guilty of gross misconduct, or are
                 substantially in breach of this Agreement, or


                                 Page 4 of 6 -
<PAGE>   5

         b.      if you are absent and unable to fulfil your duties through
                 accident or illness for a total of 180 days or more in any
                 period of twelve months.

7.       Secrecy

7.1      You shall not disclose (except in the proper course of your duties) to
         any person, firm or company, or seek to exploit at any time either
         during or after the termination of your employment with the Company
         any trade secret or confidential information relating to the business,
         plant, machinery, processes or formulae of the Company or any
         subsidiary or associated company or any customer of the Company or of
         any subsidiary or associated company.  This restriction shall cease to
         apply to information or knowledge which has come into the public
         domain other than by breach of this clause, or which is trivial or
         obvious.

7.2      Upon the termination of your employment with the Company you will
         return to the Company all property of the Company, and all records of
         any nature or description which you may have in any way relating
         directly or indirectly to the business of the Company or any customer
         of the Company.

8.       Inventions

8.1      Any procedures, processes, designs, formulae, equipment, techniques,
         specifications, methods of production or inventions, or other
         industrial property ("the said procedures or inventions") which you
         may evolve, discover, invent or improve at any time during the course
         of or arising out of your employment with the Company, including any
         of the said procedures or inventions which result from disclosures to
         you by any customer of his own procedures, inventions or machinery
         shall be disclosed to the Company and shall (subject to Sections 39 to
         42 of the Patents Act 1977) be the exclusive property of the Company
         or the customer as the case may be.

8.2      At the request of the Company, and at the expense of the Company or
         the customer as the case may be, you will make or join in such
         applications, execute such deeds and do all such other acts as are
         necessary to secure and where appropriate to register in the name of
         the Company or the customer as the case may be any letters patent,
         copyrights and/or trade marks in the United Kingdom and elsewhere in
         respect of the said procedures and inventions.

8.3      For the avoidance of doubt, it is specifically understood that the
         provisions of this Clause apply to any invention, discovery or
         improvement made by you during the course of or arising out of your
         employment with the Company, whether inside or outside normal working
         hours, and whether made with the use of the Company's premises,
         machinery or equipment or not.

8.4      For the purposes of this Clause you irrevocably appoint the Company as
         your attorney in your name to execute all documents and do all things
         which are required in order to give effect to the provisions of this
         Clause, and the Company is hereby empowered to appoint and remove at
         pleasure any person as agent and substitute for and on behalf of the
         Company in respect of all or any of the matters aforesaid.

9.       Restrictions after termination

9.1      There will be a restricted period of six months after the termination
         of your employment (however it may end).  The restricted period will
         run from the date on which you or the Company gives notice to the
         other, or in the absence of notice the date of actual termination of
         your employment.

9.2      During the restricted period you shall not:

         a.      seek or accept employment with, or perform any services not
                 authorised by the Company for, any customer of the Company for
                 whom you have rendered any services on behalf of

                 beginning of the restricted period.

                 employee or servant of the Company or any subsidiary or
                 associated company.

         c.      for yourself or for any other person, firm or company solicit

                 company who was at any time during the six months immediately
                 preceding the beginning of the restricted period a customer of
                 or otherwise in the habit of dealing with the Company or any
                 subsidiary or associated company.

         d.      for yourself or other any other person, firm or company carry
                 on or be engaged (in a similar capacity to that which you are
                 engaged by the Company hereunder) in any business which
                 competes with the Product.

10.      General.

         your employment but you are expected to conform to accepted standards
         of behavior.  If you are dissatisfied with any disciplinary decision

28th July 1994

Dear Melinda,

This Employment Agreement records your employment with Synon Research Limited
("the Company").  It supersedes your prior Employment Agreement dated 15th
September 1992.

1.       Duties and place of work

1.1      The Company shall employ you as Director of Development or in any
         other capacity as the Company may agree with you from time to time.
         You will be a Director of the Company.  You will be required to work
         at 91 St Pauls Road, London N1 2YU, or in the event of the Company or
         any of its subsidiary or associated companies no longer occupying that
         address at such other address within a three mile radius of that
         address that the Company may agree with you from time to time.  You
         may be required to travel on the business of the Company or any of its
         subsidiary or associated companies anywhere in the world (as the same
         are defined in Section 736 of the Companies Act 1985 and Section 416
         of the Income and Corporation Taxes Act 1988, respectively).  You are
         to report to the Chief Technology Officer of Synon Corporation.

1.2      You shall devote the whole of your time and attention during working
         hours to the interests and welfare of the Company and its subsidiary
         and associated companies and faithfully and diligently perform your
         duties to de best of your ability.  You may be required in pursuance
         of your duties to perform services not only for the Company but also
         for any subsidiary or associated company.

1.3      You will not during the term of your employment hereunder be directly
         or indirectly concerned, engaged or interested in any business
         competing with that of the Company except with the written consent of
         the Board of Directors of the Company, or as the holder (directly or
         through nominees) of investments listed on any recognised stock
         exchange where the holding does not exceed five per cent of the issued
         shares or stock of any class of any one company.

1.4      Under an Employment Agreement of even date between the Company and
         Simon Williams, the Company has authorised Simon Williams to employ
         and direct on its behalf a Development Team located at your place of
         work, which you shall manage.  The said Development Team may comprise,
         at Simon Williams' sole discretion, up to seventeen (17) people
         (including yourself) of appropriate skills and experience, employed at
         salaries and under terms and conditions commensurate with those that
         prevail in similar software research and development organisations
         within the London area.  The Development Team will be engaged upon
         such software product research and development projects as Synon
         Corporation shall determine from time to time.  It is a condition of
         your employment that Simon Williams is Chief Technology Officer of
         Synon Corporation and that the Company shall continue to authorise
         Simon Williams to employ the Development Team on its behalf under the
         terms and conditions set out in this clause 1.4.

1.5      The provisions of clause 1.4 shall cease to apply upon the occurrence
         of both of the following:
<PAGE>   2
                 i.       Synon Corporation and its affiliates receiving the
                          aggregate of One Hundred Million US Dollars
                          (US$100,000,000) in Receipts (as defined in clause
                          2.2 below); and

                 ii.      all commission and other sums due to you under this
                          Agreement have been paid in full when due.

2.       Remuneration and benefits

2.1      The Company will pay you a basic salary at the rate of Pound 85,000
         per annum, or such higher rate as may from time to time be agreed.

         than the 28th day of each month.

2.2      In addition to the basic salary specified in sub-clause 2.1 the
         Company shall pay to you a Commission ("the Commission") which
         (subject to the provisions of sub-clause 2.5 below) shall be such sum
         as equals one percent (1.0%) of all income revenue and other payments
         or consideration of any kind received by or on behalf of the Company
         or any subsidiary or associated company of the Company including Synon
         Corporation and its subsidiaries and associated companies during the
         period of 5 years (as specified in sub-clause 2.4 below) in respect of
         each sale or rental by way of licence or maintenance or other
         exploitation of the Product (herein meaning the Product specified in
         sub-clause 2.3 below) or any part of the Product in any language
         anywhere in the world by Synon Corporation, the Company, their
         subsidiary and associated companies and any third parties
         ("Receipts").

2.3      References to the Product herein mean the next generation workstation
         based CASE product currently being developed by the Company and all
         improvements, enhancements, modifications and new versions of that
         Product and all user documentation for that Product as it exists from
         time to time.

2.4      The Commission shall be calculated on Receipts in respect of the
         Product received:

                 i.       during the period of five (5) years commencing on 1st
                          July 1994;

                 ii.      after the aforesaid five year period in respect of
                          contracts entered by the Company or Synon Corporation
                          and their subsidiary and associated companies during
                          the said five year period.

         The Commission shall be paid monthly in arrears within thirty (30)
         days of the end of each calendar month in which the said Receipts of
         Product fees are received by or on behalf of the Company and its
         associated and subsidiary companies and Synon Corporation, and its
         associated and subsidiary companies.

2.5      The Commission due hereunder shall be due and payable to you:

         i.      during the continuance of your employment hereunder and

         ii.     after the termination of your employment hereunder.  If you
                 voluntarily terminate your employment hereunder prior to the
                 expiration of the period of 5 years referred to in sub-clause
                 2.4 above the rate of Commission referred to in sub-clause 2.2
                 shall be reduced to one half of one percent (0.5%) from the
                 date of such termination UNLESS prior to the date of such
                 termination:

                 a.       Synon Corporation has consummated a Significant

Mr. John F. Rockart

Cambridge, MA 02139


Dear Jack,

Based on our recent conversation, I would like to extend you an offer to join
the Board of Directors of the Synon Corporation effective 5/1/93.  have made a
slight adjustment to the financial agreement which reflects your desire for
some additional monetary compensation.  I hope this is satisfactory.  The
specifics of your compensation are as follows:

        (1)      Consulting fees at an annual rate of $15,000, payable monthly.

        (2)      Travel expense reimbursement for Board meeting attendance.

        (3)      An option to purchase 20,000 shares of Synon stock at a price 
                 of $1.43.

I anticipate the Board will have 4 or 5 one day meetings during the year.  In
addition I would expect you and I to have normal phone call discussions.

I very much enjoyed our first meeting and know that we share many common views
on changing the way applications are developed and delivered.  I look forward
to working with you and will let you know the Board meeting schedule for the
remainder of the year.  Please confirm your acceptance so I can notify the
other Board members.

Thanks.

                                                                   EXHIBIT 10.17



                               SECURITY AGREEMENT


         This Security Agreement is made as of September 24, 1992 between Synon
Corporation, a Delaware corporation ("Pledgee" or the "Company"), and Paul K.
Wilde ("Pledgor").


                                    RECITALS


         For value received, Pledgor has delivered to Pledgee a Note dated
September 24, 1992 (the "Note") pursuant to which Pledgor promises to pay
Pledgee the principal amount of $200,000 together with interest thereon.

         NOW, THEREFORE, it is agreed as follows:

         1.      Creation and Description of Security Interest.  For due
consideration, receipt of which is hereby acknowledged, Pledgor, hereby grants
a junior security interest in that certain residence located at 19 Royal Oaks
Court, Alamo, California 94507 (the "Residence") as security for the repayment
of the Note.  Such security interest shall be junior to any security interest
granted to any bank, savings and loan or other financial institution holding a
mortgage in the Residence.  Pledgor agrees to make such filings or execute such
documents as Pledgee reasonably requests to perfect Pledgee's security interest
in the Residence.  The Residence is sometimes referred to herein as the
"Collateral".

         2.      Pledgor's Representations and Covenants.  To induce Pledgee to
enter into this Security Agreement, Pledgor represents and covenants to
Pledgee, its successors and assigns, that Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

         3.      Default.  Pledgor shall be deemed to be in default of the Note
and of this Security Agreement in the event:

                 (a)      Payment of principal or interest on the Note shall be
delinquent for a period of fifteen (15) days or more; or

                 (b)      Pledgor fails to perform any of the obligations
contained in this Security Agreement for a period of fifteen (15) days after
written notice thereof from Pledgee.

         In the case of an event of default, as set forth above, Pledgee shall
have the right to accelerate payment of the Note upon notice to Pledgor, and
Pledgee shall thereafter be entitled to pursue its remedies under the
California commercial code.
<PAGE>   2
         4.      Withdrawal or Substitution of Collateral. Pledgor may sell
the Residence, provided that proceeds therefrom (net of selling expenses) shall
be applied immediately to the payment of the Note; such proceeds to be first
applied to accrued interest and then to principal.  Except as provided in this
Section 4, Pledgor shall not sell or otherwise transfer or dispose of any
interest in the Collateral without the prior written consent of Pledgee.

         5.      Term. The within pledge of Collateral shall continue until the
payment of all indebtedness secured hereby, at which time Pledgee's security
interest in the Collateral shall terminate. Pledgee shall make such filings or
execute such documents as Pledgor reasonably requests to release Pledgee's
security interest in the Residence.

         6.      Insolvency.  Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against him, or if a receiver is appointed for
the property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due
and payable, and Pledgee may proceed as provided in the case of default.

         7.      Invalidity of Particular Provisions.  Pledgor and Pledgee
agree that the enforceability or invalidity of any provision or provisions of
this Security Agreement shall not render any other provision or provisions
herein contained unenforceable or invalid.

         8.      Successors or Assigns.  Pledgor and Pledgee agree that all of
the terms of this Security Agreement shall be binding on their respective
successors and assigns, and that the term "Pledgor" and the term "Pledgee" as
used herein shall be deemed to include, for all purposes, the respective
designees, successors, assigns, heirs, executors and administrators.

         9.      Governing Law.  This Security Agreement shall be interpreted
and governed under the laws of the State of California.

                               [SYNON LETTERHEAD]


May 15, 1997



                              This letter encompasses the original letter dated
                              4/17/97 and the Addendum dated 5/2/97.


Mr. Kevin Kilroy
37 Springbrook Lane
New Arch, DE 97711


Dear Kevin:


I am pleased to confirm my verbal offer for you to join Synon Corporation as
Vice President, North America Sales & Marketing. This letter sets forth the
terms of your employment offer with Synon as follows:

        1.  You will serve in the position of Vice President, North America
            Sales & Marketing, reporting to the Chief Executive Officer and
            assume and discharge such responsibilities as are commensurate with
            this position. You shall comply with and be bound by Synon's
            operating policies, procedures, and practices. It is anticipated
            that the effective date of your employment will be on or about June
            3, 1997.

        2.  During the term of your employment with Synon you shall devote your
            full time, skill and attention to your duties and responsibilities,
            and shall perform them faithfully, diligently and competently, and
            you shall use your best efforts to further the business of Synon.
            Your employment with Synon is for an unspecified duration that
            constitutes at-will employment and either Synon or you can terminate
            this relationship at any time.

        3.  In consideration of your services, you will be paid a salary of
            $16,667 per month (annualized rate of $200,000), payable
            semi-monthly in accordance with Synon's standard payroll in
            practices. As with other officers of Synon, this base compensation
            will be reviewed annually by the Board of Directors.

        4.  In addition to your base compensation, the Board of Directors shall
            adopt an executive bonus program under which you shall be entitled
            to earn incentive compensation based upon the satisfaction of
            certain performance goals. It is contemplated that these performance
            objectives will be determined by the Chief Executive Officer in
            consultation with you, and will concern such matters as North
            America revenue and profitability and Corporate objectives. The
            bonus will be targeted at $75,000 annually plus additional
            overachievement milestones and will be paid according to the Payout
            Schedule, Attachment A-2. Further incentive compensation may, at the
            sole discretion
<PAGE>   2
            of the Board of Directors, be provided for overachievement of
            corporate objectives.

        5.  Your 1997 Bonus Target will be prorated for a partial year. Assuming
            a June 3 start date, the '97 target is $44K. Per our agreement, you
            will be guaranteed a minimum payout of 80%.

        6.  You will be given a non-recoverable draw of $3,000 per month for the
            first five months of employment.

        7.  You will be entitled to receive Synon's fringe benefits made
            available to other employees and officers to the full extent of your
            eligibility therefor. You shall be entitled to three weeks of paid
            vacation per year (which shall not accrue in excess of three weeks
            per year). During your employment, you shall be permitted, to the
            extent eligible, to participate in any group life, hospitalization
            or disability insurance plan, health program, or similar benefit
            plan of Synon that may be available to other comparable employees
            generally on the same terms as such other employees. Participation
            in any such plan shall be consistent with your rate of compensation
            to the extent that compensation is a determinative factor with
            respect to coverage under any such plan. Business expenses, incurred
            by you will be reimbursed according to Synon's expense reimbursement
            policy.

        8.  As long as you were covered under your prior plan and have not had
            more than a 90 day break in coverage, you will be covered without
            waiver of pre-existing conditions.

        9.  Upon your acceptance of employment you will be granted a
            non-statutory option to purchase 200,000 shares of Synon Common
            Stock under Synon's 1990 Stock Option Plan subject to approval of
            the Board of Directors. The option price shall be at the per share
            fair market value as of the date of your acceptance. The option
            shall have a term of ten years. The Option Agreement will provide
            that your right to exercise the option will vest cumulatively over a
            period of four years, vesting at 25% on the first anniversary of the
            effective date of your employment and thereafter on a monthly basis
            (2.0833% per month).

            In addition, (i) upon any Change of Control of Synon Corporation (as
            defined herein), then 25,000 shares of your unvested option shares
            shall vest and become exercisable and any of the then remaining
            unvested options will vest monthly in equal increments over the
            balance of the original vesting period and (ii) if your employment
            is involuntarily terminated or Constructively Terminated (as defined
            herein) within twelve (12) months after a Change of Control (it
            being the intention that you will agree to remain employed for at
            least one year following a "Change of Control"), then your options
            shall be accelerated to become immediately exercisable for 50% of
            the total number of unvested shares subject thereto.

       10.  In addition, if your employment is involuntarily terminated other
            than for "cause" (as defined herein) with Synon (i) prior to a
            Change of Control (as defined herein), you shall receive twelve
            months base salary as severance, or, (ii) is involuntarily
<PAGE>   3
        terminated or Constructively Terminated (as defined herein), other than
        for cause, within one year following a Change of Control then you shall
        receive 1 year's base salary as severance.

11.     For purposes of the foregoing, termination "for cause" shall mean (i)
        the willful failure by you substantially to perform your material
        duties after a written demand for substantial performance is delivered
        to you by the Chief Executive which specifically identifies the manner
        in which he believes that you have not substantially performed your
        duties; (ii) the failure (in a material respect) by you to follow a
        written, lawful order or directive from the Chief Executive; (iii) the
        conviction of you of any crime involving the property or business of
        Synon or its affiliates; or (iv) any act of moral turpitude in
        connection with the performance of your duties hereunder.
  
12.     For purposes of the foregoing, a "Change of Control of Synon" shall be
        deemed to have occurred if (i) Synon sells or otherwise disposes of all
        or substantially all of its assets; (ii) there is a merger or
        consolidation of Synon with any other corporation or corporations,
        provided that the shareholders of Synon, as a group, do not hold,
        immediately after such event, at least 50% of the voting power of the
        surviving or successor corporation; (iii) any person or entity,
        including any "person" as such term is used in Sections 13(d) and 14(d)
        of the Securities Exchange Act of 1934, as amended (the "Exchange Act")
        becomes the "beneficial owner" (as defined in Rule 13d-3 of the Exchange
        Act) of Common Stock of Synon representing 50% or more of the total
        voting power of the outstanding voting securities of Synon (exclusive of
        persons who are now officers or directors of Synon).

13.     For purposes of the foregoing, your employment with Synon shall be
        deemed to have been "Constructively Terminated" if there shall occur (i)
        a material reduction in salary or benefits (taken as a whole); or (ii) a
        material change in your responsibilities as Vice President of North
        American Sales & Marketing, or (iii) a requirement to relocate, except
        for office relocations that would not increase your one-way commute by
        more than 50 miles.

14.     Synon agrees to reimburse you for up to $63,000 in documented relocation
        expenses such as house hunting trips to the Bay Area, the cost of moving
        your household goods and personal property, temporary accommodations and
        the reimbursement of income taxes assessed on your taxable relocation
        expenses.  You agree to reimburse Synon for reimbursed relocation
        expenses should you voluntarily leave Synon within eighteen months of
        your hire date.  Synon will waive its rights to 1/18th of these
        relocation expenses for every month of continued employment.

15.     The position of Vice President, North America Sales & Marketing, is
        located at company HQ, in Larkspur, California. Relocation of your
        family to California should happen as soon as possible.  Understanding
        the need to sell your house, I will be flexible in the transaction and
        would expect this to be completed within twelve months.
<PAGE>   4
        16.  Since you will be spending considerable time in the field, your
             interim personal living expenses in California will be covered
             under T & E.

        17.  Upon acceptance of this offer, you will be required to sign
             Synon's standard employee proprietary information agreement.

I am delighted to have you as a part of the Synon Executive Team. Your
leadership will help us achieve new records. Please acknowledge acceptance of
this offer by signing and returning the enclosed copy of this letter. Synon and
you shall undertake to promptly prepare and execute all of the documents and
agreements as are reasonably necessary to carry out the intentions expressed
herein.

Very truly yours,

/s/ RICHARD H. GOLDBERG

         the purposes of this clause and giving effect thereto:

         6.1.1   the Warranties shall be separate and independent and save as
                 expressly otherwise provided shall not be limited by reference
                 to any other paragraphs of Schedule III or by anything in this
                 Agreement;

         6.1.2   the Vendors acknowledge that Synon has entered into this
                 Agreement in reliance (inter alia) upon the Warranties.

6.2      Synon shall not and shall not be entitled to institute proceedings for
         damages for breach of:

         (a)     any of the Non-IP Warranties after expiration of the period of
                 twelve months from the date of this Agreement unless notice
                 containing full details of such breach including the nature of
                 the breach and an estimate of the amount claimed is given to
                 each of the Vendors on or before the expiration of the said
                 twelve month period and thereafter any such notified claim is
                 brought and proceedings issued within eighteen months from the
                 date of this Agreement; and

         (b)     the IP Warranty after expiration of the period of sixty months
                 from the Launch Date unless notice containing full details of

                                     - 6 -
<PAGE>   9
                 including the nature of the breach and an estimate of the
                 amount claimed is given to each of the Vendors on or before
                 the expiration of the said sixty month period and any such
                 notified claim is brought and proceedings issued within that
                 sixty month period.

6.3      Synon shall not institute proceedings for damages for breach of any of
         the Warranties if such proceedings shall be in respect of a claim or
         claims aggregating less than fifty thousand British pounds sterling
         (Pound 50,000).

6.4      The total maximum liability of the Vendors for breach of any of the
         Warranties shall not exceed in aggregate the sum of Pound 243,413
         British Pounds Sterling (when each Vendor shall have a maximum
         aggregate liability equal to Pound 73,771 British Pounds Sterling plus
         the amount of the Vendor's Loan repaid to him or her at Completion)
         unless the liability is in respect of breach(es) of the IP Warranty
         when the following provisions of sub-clause 6.5 shall apply.

6.5      If the liability of the Vendors under this clause 6 for breach of the
         IP Warranty would, but for the limitation contained in sub-clause 6.4,
         take the total liability of the Vendors to in excess of the sum of
         Pound 243,413 (when adding the liability of the Vendors for breach of
         the IP Warranty to previous liability incurred by the Vendors under
         this clause 6), then in respect of any liability arising under the IP
         Warranty only the limitation in sub-clause 6.4 shall be extended so
         that:

         6.5.1   the maximum aggregate liability of the Vendors shall be such
                 sum as equal Pound 243,413 plus a sum equal to fifty percent
                 (50%) of the net commission paid to each of the Vendors by
                 Synon or any subsidiary or Affiliate of Synon under the
                 Service Contracts or any other contract of employment with the
                 Vendors relating to the


                                     - 7 -

                 Product, as at the date that any such claim is made by Synon
                 against either or both of the vendors for breach of the IP
                 Warranty; and

         6.5.2   the maximum aggregate liability of the Vendors in respect of
                 the IP Warranty shall only exceed Pound 243,413 as aforesaid
                 if Synon incurs actual liability to a third party in respect
                 of any breach of the IP Warranty, and then only to the extent
                 of fifty percent (50%) of such liability, the balance of fifty
                 percent (50%) to be met by Synon; and

         6.5.3   the maximum aggregate liability of each of the Vendors in
                 respect of their total liability exceeding Pound 243,413 as
                 aforesaid shall be divided between them as to two thirds of
                 the excess calculated in accordance with sub-clauses 6.5.1 and
                 6.5.2 to Simon Williams and one third to Melinda Horton and
                 such liability of the Vendors shall be several.

6.6      Neither of the Vendors shall have any liability in respect of any
         claim pursuant to the Warranties:

         6.6.1   to the extent that recovery is made by Synon or Dysys under
                 any policy of insurance;

         6.6.2   if the facts matter or circumstances are accurately referred
                 to in the Disclosure Letter or any document disclosed
                 thereunder; and

         6.6.3   to the extent that such matter giving rise to the claim
                 properly falls to be done in implementing the terms of this
                 Agreement.

6.7      If the Vendors satisfy a claim in respect of any of the Warranties and
         Synon having claimed for breach of Warranty has a right of
         reimbursement against any other person other than Dysys in respect of
         or relating to that claim then Synon shall (subject to it being
         indemnified and kept indemnified to its reasonable satisfaction by the
         Vendors against all reasonable costs and expenses in connection with
         such steps or

                                     - 8 -

         proceedings) if requested by the Vendors take all reasonable steps or
         proceedings to enforce such right.  If Synon subsequently recovers
         from a third party other than Dysys an amount which represents
         additional compensation in respect of any claim under the Warranties
         then Synon shall forthwith repay to each of the Vendors such sum as
         he/she paid to Synon by way of damages for breach of that Warranty up
         to a maximum of the amount he/she paid to Synon in respect of such
         breach.

6.8      If any claim is made by Synon under this Agreement notice of the claim
         shall be given or procured to be given by Synon to each of the Vendors
         forthwith upon Synon becoming aware of the breach and if the claim in
         question is as a result of or in connection with a liability to or
         from or a dispute with any third party Synon shall (subject to Dysys
         Synon and their relevant subsidiaries being indemnified against all
         liabilities costs damages and expenses which they may reasonably
         incur) take and shall procure Dysys to take such actions as the
         vendors (or either of them) may reasonably request by notice to Synon
         (including the defence of any third party action) Provided that the
         said Vendors make such request within a reasonable time of receipt by
         the Vendors of Synon's notice in connection with such liability or
         dispute so as to recover or minimise or resolve such liability or
         dispute.  Synon shall give and shall procure that Dysys shall give to
         the Vendors full facilities to investigate the claim and the extent of
         possible liability under the Warranties and at the request of the
         Vendors shall (subject to Dysys Synon and their relevant subsidiaries
         being indemnified against all liabilities costs damages and expenses
         which they may reasonably incur) allow the Vendors at their own
         expense to participate in or have the conduct of (as they may elect)
         all proceedings of whatsoever nature against the relevant third party
         arising out of or in connection with such liability or dispute in the
         name of


                                     - 9 -

         Dysys or Synon as they may consider necessary or desirable in order to
         mitigate any claim arising under this Agreement.  Neither Synon nor
         Dysys shall accept or pay or compromise any such liability or claim
         with any such third party without the Vendors prior written consent.

         the prior approval of Simon Williams).  Such bonus system shall make
         available for distribution to the said employees every six months from
         the date of this Agreement (or such other date as Simon Williams and
         Synon shall agree) a bonus fund ("the Fund") comprising in each six
         months such sum as equals one per cent (1%) of all income revenue and
         other payments or consideration of any kind received by or on behalf
         of Synon and its Affiliates (from time to time) during the previous
         six months in respect of each sale or rental by way of licence or
         maintenance or other exploitation of any kind of the Product or any
         part of the Product in any language anywhere in the world.  The fund
         shall be distributed to such employees and to the extent that Simon
         Williams shall specify to Synon (acting reasonably).  In addition on
         the occurrence of an Event of Default (as defined below) Synon shall
         forthwith pay to each of the employees terminated under sub-clause
         7.5.4 (other than Simon Williams and Melinda

                 in the development budget of Synon and its Affiliates
                 (excluding the Budget) for that same period or is reduced for
                 a period when the said Synon development budget (other than
                 the Budget) for that same period is not reduced; or

         (b)     the Budget is reduced to an extent that it delays the
                 development of the Product by six (6) months or more in the
                 opinion of Simon Williams acting reasonably; or

         7.3.2   the Product Specification contained in Annexure 2 is changed

                 that will accrue to Simon Williams and Melinda Horton on the

                 security and confidentiality; and

         7.5.4   at the request of the vendors or either of them waive or

         The Product will be an integrated CASE tool whose functions are:

         *       to support its users in designing applications;

         *       to store the application designs which its users create; and

         *       to generate from the stored application designs all source
                 code necessary to implement applications on the IBM AS/400
                 computer in both NPT and PWS operational modes.


2.       Design support

         The Product will provide facilities for users to:

         *       Describe business objects (entities and functions);

         *       Describe the decomposition of business objects into data
                 objects, programs and subroutines at a level capable of
                 implementation as an applicacion;

         *       Describe class hierarchies through which objects may inherit
                 the properties of other objects;

         *       Describe the attributes of data objects and their
                 relationships to other data objects;

         *       Describe the logic of functions and their relationships to
                 each other via an interactive action diagram editor;

         *       Describe the layout of PWS panels, NPT panels and printed
                 reports via an interactive device design editor;

         *       Describe implementation objects (physical and logical files,
                 programs and subroutines) in sufficient detail to support the
                 automatic generation of source code for implementation;

         *       Create, score and print network diagrams showing:

*        Class hierarchies
*        Object decomposition
*        Entity relationships
*        Function relationships

         *       Describe new versions of an application by specifying
                 incremental change.
<PAGE>   39
3.       Generation

         The Product will provide facilities to generate source code and help
         text to implement interactive, batch and report programs in both NPT
         and PWS environments, including:

         *       Server and NPT process code in RPG, C or COBOL, with database
                 access code in RPG, C, COBOL or SQL at the user's option;

         *       Client process code in C or COBOL;

         *       OS/400 database definition code in DDS or SQL;

         *       NPT panels in DDS or UIM, and print files in DDS;

         *       PWS panels via appropriate resource files.

         High level languages options will be decided in consultation with
         Synon subject to an analysis of the market requirement.

         Users will be able to nominate a specified version of an application
         during generation.

         The Product will include facilities to build a list of objects whose
         designs are likely to need change as a consequence of a change to the
         design of one object.


4.       Operating environment

         The Product will operate in PWS mode using an IBM AS/400 server.
         Client processors will be personal computers running DOS and Microsoft
         Windows Version 3.1 or higher, or OS/2 Version 2 or higher using the
         WIN-OS/2 environment.

         The Product will be designed to perform adequately on a personal
         computer using an Intel 486SX processor or equivalent with 8 megabytes
         of memory and 120 megabytes of disk storage.

         The Product will maintain its repository on the AS/400.

5.       Target environment

         The Product will generate applications for the IBM AS/400, using its
         native RDBMS facilities.  Interactive applications may be generated in
         both NPT and PWS mode.  PWS application clients will be personal
         computers running DOS and Microsoft Windows Version 3.1 or higher, or
         OS/2 Version 2 or higher using the WIN-OS/2 environment.

         Applications generate by the Product will be designed to perform
         adequately on a personal computer using an Intel 386SX processor or
         equivalent with 4 megabytes of memory and 60 megabytes of disk
         storage.
<PAGE>   40
6.       Authorisation

         The Product will include facilities to:

         *       Restrict the number of concurrent users to a limit specified
                 by an encrypted authorisation code;

         *       Prevent the operation of the Product on a designated AS/400
                 processor beyond a date specified by an encrypted
                 authorisation code.

         Dysys will create a program to generate encrypted authorisation codes.


7.       Class libraries and design import

         The Product will include a class library of objects from which
         user-created objects may inherit properties such that such
         user-created objects make optimal use of the Product to generate
         applications for NPT and PWS environments.

         The Product will include facilities to import as much as reasonably
         possible of the design of an application created using Synon/2E.

         The Product will include a well-defined interface via which designs
         may be imported from other CASE tools, and via which designs created
         within the Product may be exported to other generators.

8.       Documentation

         The Product will include:

         *       A user manual providing the information which users need to
                 load the Product and to begin to use it in a limited manner;

         *       A user manual providing the information which users need to
                 enable them to use all of the Product's facilities;

15th September 1992



Dear Paul,

I am writing to you to tell you about the bonus system that Dysys is proposing
to operate for its key employees, which I hope will benefit you.

Dysys intends that the system will operate as follows:

*        All employees of Dysys (except Melinda and myself) who make a
         qualifying level of contribution to KT will be eligible to participate
         in the bonus system.

*        Bonus will be payable in respect of six month bonus periods, the first
         of which will begin on the first of the month during which the first
         commercial sale of KT occurs.  At the end of each bonus period:

         *       We will create a bonus pool of one percent of the revenue
                 received by the Synon group in respect of worldwide sales and
                 maintenance of KT during the prior six months.

         *       We will tell you the percentage of the bonus pool which you
                 will receive (your "bonus percent"), and what your actual
                 bonus will be.  Your bonus will be paid together with your
                 monthly salary for the month after the end of the bonus
                 period.

*        In determining your bonus percent, we will take into account both your
         cumulative contribution to KT since you joined Dysys, and your
         contribution to KT during the relevant bonus period, with greater
         emphasis on the former.

*        If we decrease your bonus percent from one period to another, we will
         discuss with you the reasons why, and what you need to do to restore
         it to its former level.

*        Bonuses are paid at Dysys' discretion, and are not a contractual
         right.  No-one's bonus percent will exceed 25% of the bonus pool in
         any bonus period.

*        If you leave the company during a bonus period, you may still be
         eligible for a bonus, provided that you finish any important tasks
         which you have in progress, and hand over your work to someone else in
         an orderly way.


/2
<PAGE>   47

Our present intention is that, based on your current performance, if KT is
ready for launch by lst January 1994, your initial bonus percent will be 15%.
It will decrease by 1% for every additional month which we take to complete the
product.

I hope you find this concept an exciting opportunity.  It is intended to give
you an immediate real benefit which doesn't carry the risk and uncertainty
associated with share options, which can go down in value as well as up, and
which do not vest for three years.  The bonus scheme will, therefore, replace
the idea of share options being available to employees.

Yours sincerely,





Simon Williams

         London.  These sums will be repaid by deduction from your salary in
         equal monthly instalments.  Any such sum owed by you to the Company
         upon termination of your employment will be immediately repayable.

15th September 1992



Dear Richard,

I am writing to you to tell you about the bonus system that Dysys is proposing
to operate for its key employees, which I hope will benefit you.

Dysys intends that the system will operate as follows:

*        All employees of Dysys (except Melinda and myself) who make a
         qualifying level of contribution to KT will be eligible to participate
         in the bonus system.

*        Bonus will be payable in respect of six month bonus periods, the first
         of which will begin on the first of the month during which the first
         commercial sale of KT occurs.  At the end of each bonus period:

         *       We will create a bonus pool of one percent of the revenue
                 received by the Synon group in respect of worldwide sales and
                 maintenance of KT during the prior six months.

         *       We will tell you the percentage of the bonus pool which you
                 will receive (your "bonus percent"), and what your actual
                 bonus will be.  Your bonus will be paid together with your
                 monthly salary for the month after the end of the bonus
                 period.

*        In determining your bonus percent, we will take into account both your
         cumulative contribution to KT since you joined Dysys, and your
         contribution to KT during the relevant bonus period, with greater
         emphasis on the former.

*        If we decrease your bonus percent from one period to another, we will
         discuss with you the reasons why, and what you need to do to restore
         it to its former level.

*        Bonuses are paid at Dysys' discretion, and are not a contractual
         right.  No-one's bonus percent will exceed 25% of the bonus pool in
         any bonus period.

*        If you leave the company during a bonus period, you may still be
         eligible for a bonus, provided that you finish any important tasks
         which you have in progress, and hand over your work to someone else in
         an orderly way.



/2
<PAGE>   54

Our present intention is that, based on your current performance, if KT is
ready for launch by lst January 1994, your initial bonus percent will be 20%.
It will decrease by 1% for every additional month which we take to complete the
product.

I hope you find this concept an exciting opportunity.  It is intended to give
you an immediate real benefit which doesn't carry the risk and uncertainty
associated with share options, which can go down in value as well as up, and
which do not vest for three years.  The bonus scheme will, therefore, replace
the idea of share options being available to employees.

Yours sincerely,





Simon Williams

         the same available to you for inspection (and if requested copying) by
         you or your representative no more frequently than once in any six (6)
         month period.

2.8      If any Commission payable to you hereunder is not paid by the due date

         manifest error.  The costs of such expert shall be borne as to fifty

         may give you written notification of this, detailing the specific
         reasons.  The Company may then subsequently terminate your employment

         performance.  Notice of termination will be given to you not sooner
         than one month nor later that three months after the date of the

                 accident or illness for a total of 180 days or more in any
                 period of twelve months.

         plant, machinery, processes or formulae of the Company or any
         subsidiary or associated company or any customer of the Company or of
         any subsidiary or associated company.  This restriction shall cease to

         of or arising out of your employment with the Company, including any

         c.      for yourself or for any other person, firm or company solicit

                 objects, programs and subroutines at a level capable of
                 implementation as an application;

         *       Describe class hierarchies through which objects may inherit
                 the properties of ocher objects;

         *       Describe the attributes of data objects and their
                 relationships to other data objects;

         *       Describe the logic of functions and their relationships to     
                 each other via an interactive action diagram editor;

*        Describe the layout of PWS panels, NPT panels and printed reports via
         an interactive device design editor;

         manifest error.  The costs of such expert shall be borne as to fifty
         percent (50%) by the Company and 50% by you unless such expert shall
         decide chat one party has acted unreasonably in which case he shall
         have discretion as to costs.

         and you shall not be entitled to any additional remuneration in
         respect of the unused entitlement.

6.       Term and termination.

6.1      Your employment with the Company commenced on 1st January 1992, and no
         previous employment counts as part of your continuous period of
         employment with the Company.

6.2      Unless previously terminated under other provisions of this clause
         your employment with the Company will continue until terminated by
         either party giving one month's written notice to the other.

6.4      In the event of your performance proving unsatisfactory, the Company
         may give you written notification of this, detailing the specific
         reasons.  The Company may then subsequently terminate your employment

10.0     WARRANTIES

1.       Synon represents and warrants that it has the right to grant the
         rights and licenses granted in this Agreement, and that it is under no

         restrictions, which would conflict with Synon's obligations under this
         Agreement.

2.       Synon further represents and warrants that to the best of its
         knowledge at the time it furnishes the New Product and Related
         Documentation to IBM, Synon shall either have full and complete right,
         title, and interest, or full and complete right to grant the licenses

         the New Product or Related Documentation, shall infringe any trade
         secret, copyright, patent or other intellectual property right, or
         privacy or similar right, of a third party.  If requested by IBM,
         Synon shall defend IBM and its Subsidiaries against any claim that
         IBM's exercise of its rights and licenses granted in the Section,
         entitled "Use of New Product and Related Documentation" infringes a
         third party's trade secret, copyright, patent, or other intellectual
         property right or privacy right, provided that IBM promptly notifies
         Synon in writing of the claim, and provides Synon with the sole
         control of the defense and settlement thereof.

3.       If the New Product or Related Documentation, or any part thereof, are,
         or in the opinion of Synon may become, the subject of any claim, suite
         or proceeding for such an infringement, then Synon may, at its option
         and expense:

         a.      replace the New Product and Related Documentation, or part
                 thereof, with another non-infringing New Product and Related
                 Documentation or parts that are substantially equivalent in
                 functionality and performance; or

         b.      similarly modify the New Product and Related Documentation, or
                 part thereof to render them non-infringing; or

         c.      obtain a valid license under reasonable terms and cost for IBM
                 to use the New Product and Related Documentation; or

         d.      failing a. b. or c. above, terminate this Agreement and
                 promptly repay to IBM all funds lent to Synon under this 
                 Agreement.

         Notwithstanding the foregoing, Synon assumes no liability for (i) any
         infringement claims with respect to any product in or with which the
         New Product and Related Documentation may be used but not covering the
         New Product and Related Documentation standing alone; (ii) any
         trademark infringements involving any marking or branding applied at
         the request of IBM; or (iii) the modification of the New Product and
         Related Documentation, or any part thereof, unless such modification
         was made by Synon.

         THIS SECTION 10.0 STATES THE ENTIRE LIABILITY AND OBLIGATION OF SYNON
         AND THE EXCLUSIVE REMEDY OF IBM, WITH RESPECT TO ANY ALLEGED
         INFRINGEMENT OF PATENTS, COPYRIGHTS.  TRADEMARKS OR OTHER INTELLECTUAL

4.       EXCEPT AS EXPRESSLY PROVIDED IN THIS SECTION 10.0, SYNON MAKES NO
         REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT TO THE
         NEW PRODUCTS OR ANY OTHER MATERIALS OR SERVICES PROVIDED HEREUNDER.

11.0     MAINTENANCE SUPPORT

Synon shall provide Customer maintenance support for the New Product and
Related Documentation at a level equivalent to the level of support Synon
provides for its current "Synon/2E" software product offering and its related
documentation.

For the purpose of this Section 11.0, maintenance support shall include
updating the New Product and Related Documentation to be compatible with future
releases of IBM products on which the New Product depends on or with which it
interfaces.

If Synon materially breaches its obligations to provide maintenance support to
its Customers for the New Product and Related Documentation, IBM will have the
right to use the Source Code held in deposit at a single central technical
support location, solely for the purpose of providing maintenance support to
such Customers.

Synon's failure to correct all or any particular Errors or to enhance the New
Product and Related Documentation shall not constitute a breach.

12.0     IBM'S RIGHT TO SELL NEW PRODUCT

IBM reserves the right to nominate the New Product and Related Documentation
for which development is completed under this Agreement as a candidate for sale
by IBM through its Cooperative Software Supplier Program (CSSP) marketing
channel.  If IBM exercises this right, the parties agree to negotiate in good
faith at that time to enter into an IBM CSSP agreement".

IBM may exercise its right under this Section 12.0 with respect to the New
Product and Related Documentation by giving written notice to Synon of its
intention and entering into a mutually acceptable IBM CSSP agreement concerning
the New Product and Related Documentation within 6 months after the date such
New Product and Related Documentation are made generally available for sale by
Synon.

13.0     AGREEMENT WITH SYNON EMPLOYEES

Synon agrees that it shall have and maintain for so long as this Agreement is
in effect, written agreements with all of its employees, subcontractors or
agents engaged by Synon to assist with or contribute to Synon's duties,
obligations or performance under this Agreement.  Such written agreements shall
contain provisions sufficient to establish the rights and benefits contemplated
by, and to assure compliance with the Sections, entitled "Information Exchange"
and "Rights In Data".

14.0     TERM AND TERMINATION

1.       Stated Term

         The effective date of this Agreement is the date Synon and IBM
         Authorized Signing Officers sign this Agreement and shall expire upon
         Synon's complete repayment to IBM of all funds lent to Synon under
         this Agreement.

2.       Termination without Cause

         Either party may, at its sole option and discretion, terminate this
         Agreement, in whole or in part, with or without reason by giving the
         other party 30 days prior written notice.

         If this Agreement is terminated by IBM for convenience, IBM shall
         continue to loan those funds which would have been loaned to Synon had
         this Agreement not been terminated for 3 months following the date of
         termination.  The balance of loaned funds outstanding at the end of
         this 3 month period shall be repaid on a prorated basis in accordance
         with the original repayment schedule, without interest.

         If this Agreement is terminated by Synon for convenience, IBM's
         obligation to continue loaning funds shall terminate on the date such
         notice is given, and the balance of loaned funds outstanding on the
         date of such termination shall be repaid within 12 months following
         the date of such termination, with interest from the date of
         termination.

3.       Termination for Cause:

         This Agreement may be terminated by either party in the event of a
         material breach by the other party of its obligations hereunder and
         after written notice to the other party has been given which
         specifically identifies the breach for which termination is
         threatened.  If the breaching party does not (i) reach agreement with
         the non-breaching party within 30 days of such notice on a plan to
         cure such breach, or (ii) present a plan to the non-breaching party
         within 30 days of such notice that provides for a cure within 90 days
         of the notice of breach, and actually cures the breach within such 90
         day period, then in either case the non-breaching party may terminate
         this Agreement effective upon a further written notice of termination
         given to the breaching party.  Termination shall not occur if the
         above conditions are met.

         If this Agreement is terminated by IBM due to a material breach by
         Synon, the balance of loaned funds outstanding at the date of
         termination shall be repaid with interest from the date of termination
         within 12 months after the date of termination.

         If this Agreement is terminated by Synon due to a material breach by
         IBM, IBM shall continue to loan those funds that would have been
         loaned to Synon, had this Agreement not been terminated for 3 months
         following the date of termination.  The balance of loaned funds
         outstanding at the end of this 3 month period shall be repaid on a
         prorated basis in accordance with the original repayment schedule,
         without interest.

         and shall inure to the benefit of and be binding upon the parties and
         their legal representatives, heirs, successors and assigns:

         c.      Information Exchange;

         e.      Term and Termination;

         f.      Trademark and Trade Names Usage; and

         g.      General.

5.       Limited Effect

         In addition, in the event of termination or expiration of this
         Agreement, both parties shall have all rights which they would have
         had if they had never entered into this Agreement and which the public
         has at the time of such termination.

15.0     FREEDOM OF ACTION/OTHER VENDORS

         This Agreement shall not prevent either party from entering into
         similar agreements with other parties or from independently developing
         or acquiring materials, products, or services irrespective of their
         functional similarity to materials, products, or services which may
         result from this Agreement.

16.0     TRADEMARK AND TRADE NAMES USAGE

         Nothing in this Agreement confers upon either party any right to use
         the other party's name, trademark(s) or trade name(s) or similar
         matters in connection with any product, service, promotion, or
         publication, except that Synon may represent that the New Product
         developed under this Agreement is strategic to IBM and is System
         Application Architecture compliant and fits in AD Cycle for IBM's mid
         range computers, if such is the case, and if Synon's reference to IBM
         is not misleading.

                  CROSS SYSTEM PRODUCT/EXTERNAL SOURCE FORMAT

                              SYNON/2E GENERATION

                                DEVELOPMENT PLAN

I.       BUSINESS REQUIREMENTS

The AD/Cycle partnership requires bi-directional support for Cross System
Product to support communications between AD/Cycle tools.  Import of external
source format is handled through Synon's AD/Interface Product.  Export of
external source format will be a separate generator option for Synon/2E.

This product will allow the developer to use Synon/2E design specifications to
generate external source format specifications.  This generator will
're-export' imported ESF as functionally equivalent or identical ESF as
appropriate.  The exported ESF will be transferred to other platforms for use
with Cross System Product or PS/2-based analysis and design tools.

II.      FUNCTIONAL REQUIREMENTS

A.       The generator must be able to generate ESF for any appropriate target
environment.  The user must be able to specify the target environment.

B.       The generator must map all Synon/2E elements to appropriate ESF
elements.

C.       The import history stored when importing ESF to Synon/2E through
AD/Interface must be used during ESF export.

III.     ANCILLARY REQUIREMENTS

A.       Function options and definition of ESF export files and source members
must be included by Synon/2E Release 3.0.

B.       Documentation of the ESF generator must be included in Synon/2E
product documentation.

C.       An ESF export manual explaining the target environments and the
Synon/2E - ESF mapping must be developed.

D.       A facility for transferring the exported ESF to the PS/2 must be
included with the ESF generator.

IV.      DEVELOPMENT PHASES

The following outline contains each development phase, its tasks, and the
expected deliverables from this stage.  Target completion dates will be
reviewed at the end of each phase and subsequent dates will be adjusted if
necessary.  The Synon Development Manager and the IBM liaison will be
responsible for reviewing the schedules and determining the completion of
deliverables.

V.       IBM ASSISTANCE & DEPENDENCIES

A.       EXTERNAL DESIGN PHASE

During this phase, a detailed knowledge of CSP target environments will be
required.  The assignment of a knowledgeable IBM employee to this phase would
ensure the proper mapping of Synon/2E elements of ESF.  Estimated project time
is four months.

B.       QUALITY ASSURANCE

Generated external source format will need to be tested in a number of
environments.  Synon does not own or have access to the appropriate hardware
facilities.  As well, a large number of test cases have already been designed
for ESF and CSP.  Assistance will be required from IBM to assist Synon in the
design of test cases and in the actual testing.  This assistance will need to
be in the form of both hardware facilities and personnel.

C.       BETA TEST

Synon will need assistance in identifying and contracting with beta test sites.

3.0  HANDLING OF DISCLOSURES

3.1  All disclosures of information by one party to the other party pursuant to
this Agreement shall be made by or under the supervision of a Technical
Coordinator of the disclosing party to a Technical Coordinator of the receiving
party or his designee. Such Technical Coordinators are designated in Section 5.
All disclosures of Information will be deemed to be nonconfidential unless
specifically designated at the time of disclosure (as provided in Section 3.2
below) as including the Confidential Information of Synon or IBM, as the case
may be. With respect to all such Information disclosed by one party to the other
party, except such Information as is so designated as the Confidential
Information of the disclosing party, and subject to any patents or statutory
copyrights existing in published materials at the time of the disclosure, the
disclosing party grants to the receiving party, to the extent, if any, of its
interest therein, a nonexclusive, royalty free, irrevocable, unrestricted, and
worldwide license to use, have used, disclose to others, make copies in the case
of documents, and dispose of, all without limitation, such nonconfidential
Information in any manner it

                                                     CDA Date: February 26, 1990


determines, including the use of such nonconfidential Information in the
development, manufacture, marketing, and maintenance of products and services
incorporating such nonconfidential Information.

3.2 Prior to disclosing any Confidential Information, the disclosing party shall
provide the receiving party's Technical Coordinator with a nonconfidential
general description of the Confidential Information. The receiving party's
Technical Coordinator shall give his written agreement that the receiving party
understands the nature of the Confidential Information and will accept it or not
accept it. With respect to all Confidential Information, when such is disclosed
in writing and accepted, such writing will state the date of disclosure, that
the information contained therein is Confidential and that it is being disclosed
pursuant to this Agreement, and will contain the legend "IBM Confidential" or
"Synon Confidential" Information as the case may be. If such disclosure is
orally and/or visually made, the disclosure shall be clearly identified at the
time of disclosure as being Confidential and confirmed in a written resume
within twenty days following such disclosure. The resume will specifically
recite that information which is Confidential.

3.3 Subject to the provisions of Sections 3.4 and 3.5, for a period of five (5)
years from the date of disclosure, the receiving party agrees to use the same
care and discretion to avoid disclosure, publication, or dissemination outside
of the receiving party of received "Synon Confidential" Information or "IBM
Confidential" Information as the case may be, as the receiving party employs
with similar information of its own which it does not desire to publish,
disclose, or disseminate. Annex I attached hereto shall define minimum standards
of care.

3.3.1 During such period, the receiving party agrees to limit the dissemination
of the Confidential Information of the other party to those of its employees
having a need to know such Confidential Information. It is understood that
receipt of Confidential Information under this Agreement shall not create any
obligation in any way limiting or restricting the assignment and/or reassignment
of IBM employees within IBM and Synon employees within Synon.

3.3.2 The receiving party may not copy the other party's Confidential
Information. If additional copies are required by the receiving party, they will
be provided or authorized in writing by the disclosing party upon receipt of a
written request from the receiving party.

3.3.3 Within two months following the expiration or termination of this
Agreement as provided in Section 5, the receiving party will return to the
disclosing party, or destroy at the disclosing party's option, all writings and
resumes received from the disclosing party and copies thereof, containing such
Confidential Information (except for one copy thereof which shall be retained by
the receiving party for archival pur-

poses).  The receiving party will not be obligated to transfer to the
disclosing party any reports and/or other written documentation prepared by the
receiving party.

Confidential Information, the reports and written documentation referred to in

therein for any purpose including the use of such Confidential Information in
the development, manufacture, marketing and maintenance of its products and
services, subject only to the obligation not to disclose, publish or disseminate
such Confidential Information during such foregoing specified period of
confidentiality and subject to statutory copyrights, if any.

3.3.5 Following the period of confidentiality, no obligation of any kind is
assumed by, or is to be implied against the receiving party, with respect to any
Confidential Information, and the receiving party shall be free, subject to any
statutory copyright, to disclose, publish and disseminate such Confidential
Information to others without limitation and shall have all the rights relative
to such Information as are set forth in Section 3.1 as if it had been
transferred as nonconfidential Information under such Section.

3.4 Disclosure of Confidential Information shall not be precluded if such
disclosure is:

     1.   in response to a valid order of a court or other governmental body of
          the United States or any State or any political subdivision thereof;
          provided, however, that the party responding to the order shall first
          have given notice to the other party and made a reasonable effort to
          obtain a protective order requiring that the Confidential Information
          and/or documents so disclosed be used only for the purposes for which
          the order was issued; or

     2.   otherwise required by law, or

     3.   necessary to establish rights under this Agreement.

3.5 Notwithstanding any other provisions of this Agreement, the obligations 
specified in Section 3.3 above will not apply to any information that:

     1.   is already in the possession of the receiving party without obligation
          of confidence;

     2.   is independently developed by the receiving party or any of its
          Subsidiaries;

     3.   is or becomes publicly available without breach of this Agreement;

     4.   is rightfully received by the receiving party from a third party;

     5.   is released for disclosure by the disclosing party with its written
          consent;

Dear Mr. Herron:

         IBM is planning to release to you IBM Confidential information for
several enabling activities relating to OS/2, CSP ESF Interface, etc. Prior to
releasing this information, we must have a Confidential Disclosure Agreement
(CDA) signed.  Attached for signature are three (3) copies of CDA Number

copies to J. W. Krier at the address shown on page 8 of the Agreement, and
retain the third copy for your files.

         A security audit must also be done at your location.  Someone from IBM
will be calling you to schedule this audit in the very near future.



                                        Sincerely,

                                        /s/ HENRY P. FUHRMANN

          b.   designated IBM Internal Use Only, IBM Confidential, or IBM
               Confidential Restricted;

     2.   For the purposes of this Confidential Disclosure Agreement, IBM may

grams") which shall be deemed to be IBM Confidential as defined in this
Confidential Disclosure Agreement.  Such Proprietary Programs will be provided
without charge for the period deemed necessary by IBM to accomplish the
objectives of, but not to exceed expiration or termination whichever first
occurs of, this Agreement.  Such Proprietary Programs shall be made available
to Vendor subject to the following additional conditions:

     a.   Proprietary Programs are not to be copied by Vendor without receiving
          IBM's prior written approval.

     b.   Vendor shall take the necessary steps to ensure that the Proprietary
          Programs shall be used solely for the purposes of this Agreement and
          for the benefit of IBM.

     c.   IBM may correct errors in the Proprietary Programs and issue corrected
          copies. IBM does not represent or warrant that any or all errors will
          be corrected.

     d.   IBM personnel shall have access to the Proprietary Programs during
          Vendor's normal business hours for programming maintenance services
          and observation during the period of their utilization.

     e.   IBM may, at its option, at any time during the term of this Agreement,
          substitute IBM Proprietary Programs needed to carry out any activity
          under this Agreement.

     f.   Vendor agrees not to provide or make available any Proprietary Program
          or portions thereof without written consent of IBM, to any person
          other than Vendor employees who have a need to know.

     g.   Within one week after expiration or termination of this Agreement,
          Vendor will, at IBM's sole option, either certify to IBM in writing
          that all Proprietary Programs and authorized copies have been
          destroyed or have become licensed for use under the terms and
          conditions of IBM's then applicable Program License Agreement at IBM's
          then applicable charges.

3.   Vendor understands that IBM does not wish to receive from Vendor any
     information which may be considered confidential and/or proprietary to
     Vendor and/or to any third party. Vendor represents and warrants that any
     information disclosed by Vendor to IBM is not confidential and/or
     proprietary to Vendor and/or to any third party. Accordingly, except with
     respect to Vendor's rights under valid patents and statutory copyrights, no
     obligation of any kind is assumed by or to be implied against IBM by virtue
     of IBM's discussions and/or correspondence with Vendor or with respect to
     any information received (in whatever form or whenever received) from
     Vendor relating to the subject matter hereof, and IBM will be free to
     reproduce and to use and disclose to others such information without
     limita-

     tion. Vendor understands that IBM may now market or have under development
     products which are competitive with products or services now offered or
     which may be offered by Vendor. Moreover, discussions and/or communications
     between the parties will not serve to impair the right of either party to
     develop, make, use, procure, and/or market products or services now or in
     the future which may be competitive with those offered by the other, nor
     require either party to disclose any planning or other information to the
     other.

4.   All disclosures of information by IBM to Vendor pursuant to this Agreement
     shall be made by or under the supervision of a Technical Coordinator of IBM
     to a Technical Coordinator of Vendor or its designee. All disclosures of
     information will be deemed to be non- confidential unless specifically
     designated at the time of disclosure (as provided in Section 5 below) as
     including the Confidential Information of IBM. With respect to all such
     information disclosed by IBM to Vendor, except such Information as is so
     designated as the Confidential Information of IBM or is protected by
     statutory copyright, IBM grants to Vendor, to the extent, if any, of its
     interest therein, a nonexclusive, royalty free, irrevocable, unrestricted,
     and worldwide license to use, have used, disclose to others, make copies in
     the case of documents, and dispose of, all without limitation, such
     non-confidential information in any manner it determines, including the use
     of such non-confidential information in the development, manufacture,
     marketing, and maintenance of products and services incorporating such
     non-confidential information.

5.   With respect to the Confidential Information of IBM, when such is disclosed
     in writing, such writing will state the date of disclosure, that the
     information contained therein is confidential and that it is being
     disclosed pursuant to this Agreement, and will contain an appropriate
     legend, such as "IBM Confidential." If such disclosure is orally and/or
     visually made then it shall be confirmed in a written resume within twenty
     (20) days following such disclosure. The resume will specifically recite
     that information which is confidential. Such resume will have such
     information which is confidential identified as "IBM Confidential." IBM
     Confidential Information is not to be copied by Vendor without receiving
     prior written approval from IBM to copy a specific document.

     IBM Confidential Information is to be used by Vendor solely for the benefit
     of IBM.

     When Vendor generates a work product using IBM Confidential Information,
     all tangible forms of that work product, including but not limited to,
     texts, drawings, computer print-outs, etc., will have each page labeled
     "IBM Confidential/Prepared by Vendor." This work product will be handled in
     the same manner as the original IBM Confidential Information transmitted to
     Vendor.

6.   Subject to the provisions of Sections 7 and 8, for a period of five (5)
     years from the date of receipt of IBM Confidential Information, as measured
     from the date of first receipt under this Agreement, Vendor agrees not to
     disclose received IBM

     Confidential Information outside of Vendor's designated location and/or to
     any person other than those persons within Vendor's organization who have a
     need to know such IBM Confidential Information. Vendor also agrees not to
     disclose received IBM Confidential Information to IBM employees not
     directly having a need to know such IBM Confidential Information without
     prior written approval of the IBM Contracts Administrator identified in
     this Agreement. IBM and Vendor agree that the items set forth in Annex I
     are illustrative, but not all inclusive, of steps that should be taken by
     Vendor with respect to the Confidential Information of IBM to meet the
     standard of care recited in the foregoing sentence.

     During such period, Vendor agrees to limit the dissemination of IBM
     Confidential Information to those of its employees having a need to receive
     such information. It is understood that receipt of IBM Confidential
     Information under this Agreement shall not create any obligation in any way
     limiting or restricting the assignment and/or reassignment of Vendor's
     employees.

     Vendor shall have written agreements with its employees and subcontractors,
     sufficient to enable Vendor to comply with all the terms of this Agreement.
     Vendor's written agreement with its employees and subcontractors should
     provide for coverage of the following items:

     a.   IBM Confidential Information is to be defined based on the definition
          set forth in Section 1 of this Agreement,

     b.   IBM Confidential Information unrelated to the subject of this
          Agreement which is inadvertently disclosed to Vendor employees is not
          to be disclosed to any third party or other Vendor or subcontractor
          employees,

     c.   Information which is confidential to others and known to Vendor
          employees will not be disclosed to IBM, and

     d.   Any IBM Confidential Information or materials to which Vendor
          employees have access to or have been entrusted with will not be
          removed from IBM premises without prior written approval from IBM and
          shall return all IBM Confidential Information and materials to the
          responsible IBM Manager before leaving IBM premises.

     e.   Vendor employees will comply and do all things necessary for IBM and
          its subsidiaries to comply with the laws and regulations of all
          governments under which IBM and its subsidiaries do business, and with
          provisions of contracts between any such government and its
          contractors and IBM and its subsidiaries that relate to intellectual
          property or to the safeguarding of information.

     IBM's written approval is required prior to the disclosure of Confidential
     Information to a subcontractor.

     Upon written request from IBM or within fifteen days following the
     expiration of this Agreement as provided in Section 10, Vendor will return
     to IBM all writings and resumes received from IBM and copies thereof
     containing such IBM Confidential Information. IBM will not be obligated to
     transfer to Vendor any reports and/or other written documentation prepared
     by Vendor for IBM as a part of, or in conjunction with, this subject
     matter.

     Following the specified period of Confidentiality no obligation of any
     kind, subject to the statutory copyrights and patent rights of IBM, is
     assumed by, or is to be implied against, Vendor, with respect to any
     Confidential Information, and Vendor shall be free to disclose, publish and
     disseminate such Confidential Information to others without limitation and
     shall have all the rights relative to such Information as are set forth in
     Section 4 as if it had been transferred as non-confidential information
     under such section subject to any related Agreements that are executed
     between the parties.

7.   Disclosure of IBM Confidential Information shall not be precluded if such
     disclosure is:

     a.   in response to a valid order of a court or other governmental body of
          the United States or any political subdivision thereof; provided,
          however, that Vendor shall first have given notice to IBM and made a
          reasonable effort to obtain a protective order requiring that the IBM
          Confidential Information and/or documents so disclosed be used only
          for the purposes for which the order was issued; or

     b.   otherwise required by law; or

     c.   necessary to establish rights under this Agreement.

8.   Notwithstanding any other provisions of this Agreement, the obligations
     specified in Section 6 above will not apply to any information that:

     a.   is already in the possession of Vendor or any of its Subsidiaries
          without obligation of confidence;

     b.   is independently developed by Vendor or any of its Subsidiaries;

     c.   is or becomes publicly available without breach of this Agreement;

     d.   is rightfully received by Vendor from a third party, without
          obligation of Confidentiality;

     e.   is released for disclosure by IBM with its written consent; or

     f.   is inherently disclosed in the use, lease, sale or other distribution
          of, or publicly available supporting documentation for, any present or
          future product or service by or for IBM or any of its Subsidiaries.

9. "Subsidiary" shall mean a corporation, company, or other entity:

     a.   more than fifty percent (50%) of whose outstanding shares or
          securities (representing the right to vote for the election of
          directors or other managing authority) are; or

     b.   which does not have outstanding shares or securities, as may be the
          case in a partnership, joint venture or unincorporated association,
          but more than fifty percent (50%) of the ownership interest
          representing the right to make the decisions for such corporation,
          company or other entity is:

     now or hereafter, owned or controlled, directly or indirectly, by a party
     hereto, but such corporation, company or other entity shall be deemed to be
     a Subsidiary only so long as such ownership or control exists.

10.  The term of this Agreement shall be effective from the date of execution of
     all parties and shall extend through April 1, 1991, with the option of
     further extension at the sole discretion of IBM.

12.  No license or immunity is granted by this Agreement by either party to the
     other, either directly or by implication, estoppel, or otherwise, under any
     patents. None of the information which may be disclosed shall constitute
     any representation, warranty, assurance or guarantee by either party to the
     other with respect to the infringement of patents or other rights of
     others.

13.  The rights and obligations of Sections 6 and 11 of this Agreement shall
     survive and continue after any expiration or termination of this Agreement
     and shall bind the parties and their legal representatives, successors and
     assigns.

14.  Each party agrees to comply with, and do all things necessary for the other
     party to comply with, all applicable Federal, State and local laws,
     regulations and ordinances, including but not limited to the Regulations of
     the United States Department of Commerce relating to the Export of
     Technical Data, insofar as they relate to the activities to be performed

     it or the direct product related thereto.

15.  This Agreement shall be construed in accordance with the law of the State
     of New York.

16.  This Agreement may be executed in one or more counterparts, all of which

Ms. M. Selig
Synon, Inc.
1100 Larkspur Landing Circle
Larkspur, California
USA 94939

The Customer (you) and International Business Machines Canada (IBM) agree that
these terms and conditions apply when IBM discloses its confidential
information (IBM Confidential Information) to you.  Specific IBM Confidential
Information is described in a Supplement to Agreement for Receipt of IBM
Confidential Information (Supplement).  Such information becomes subject to
this Agreement on the Effective Date listed in a Supplement which the parties
sign before or promptly after such disclosure.  The Supplement may also contain
additional terms and conditions.

     1.   DISCLOSURE

          IBM will identify IBM Confidential Information at the time of
          disclosure and promptly send you a written confirmation.

     2.   DELIVERY AND USE

          You will identify in the Supplement your Point of Contact for receipt
          of IBM Confidential Information. IBM and your Point of Contact will
          coordinate and control the delivery of IBM Confidential Information.
          You will use the same care and discretion to avoid disclosure,
          publication or dissemination of IBM Confidential Information as you
          employ with similar information of your own which you do not desire to
          disclose, publish or disseminate. You may disclose IBM Confidential
          Information to your employees or to employees of any of your
          Subsidiaries who have a need to know such information. Prior to
          disclosure, you will have an appropriate written agreement with any
          such employee or Subsidiary. You may disclose IBM Confidential
          Information to others provided, prior to disclosure, you have an
          appropriate written agreement with the other party and IBM approves
          such disclosure in writing.

Dear Mr. Jaeger,

CONFIDENTIAL DISCLOSURE AGREEMENT


International Business Machines Corporation (IBM) proposes to give Synon,
Incorporated (Synon) access to information which is confidential to IBM (IBM
Confidential Information).  The IBM Confidential Information pertains to
AS/400* development activities conducted at IBM's facility in Rochester, MN.
Synon and IBM agree the terms and conditions of this Confidential Disclosure
Agreement (Agreement) apply as follows:

* 400 is a registered trademark of the IBM Corporation.


1.   Synon Information

     IBM does not want to receive from Synon, and Synon agrees not to disclose
     to IBM, any information that is of a confidential or proprietary nature to
     Synon or a third party.

     All information and materials which IBM obtains from Synon in connection
     with this Agreement shall be deemed nonconfidential, and, except with
     respect to Synon's rights under valid patents and Federal statutory
     copyrights, IBM shall be free to use in any manner, for any purpose, and to
     disclose to others, any ideas, concepts, know-how and techniques received
     from Synon under this Agreement.

2.   IBM Confidential Information

     "IBM Confidential" information means information or materials that IBM
     identifies as confidential and discloses to Synon under this Agreement. It
     does not include information that rightly becomes public, or that Synon
     otherwise knows or receives without obligation of confidence. For two (2)
     years from the date of this Agreement, Synon shall hold all IBM
     Confidential information in trust and confidence for IBM and shall not

     use any IBM Confidential information except as explicitly approved by IBM.
     If any materials containing any IBM Confidential information are lost,
     Synon shall promptly notify IBM. Upon termination of this Agreement, Synon
     shall deliver to IBM all materials containing any IBM Confidential
     information.

3.   Scope of IBM Disclosure

     IBM will not be obligated to disclose any particular information to Synon.

4.   Manner of Disclosure

     IBM Confidential information may be disclosed to Synon visually, orally, or
     in writing (including graphic material). When disclosed in writing, the
     information will be labeled "IBM CONFIDENTIAL." When disclosed visually or
     orally, the information will be identified as IBM Confidential at the time
     of disclosure. Synon agrees to clearly label as "IBM CONFIDENTIAL" all
     information reduced to writing or graphics as a result of IBM's visual or
     oral disclosures.

5.   Dissemination

     Synon will limit dissemination of IBM Confidential information to those of
     its employees with a need to know. Synon will not copy any IBM Confidential
     information without prior written approval from IBM.

     Synon will have an appropriate written agreement with each of its employees
     or other persons whose services Synon may require, sufficient to enable
     Synon to comply with all of the provisions of this Agreement.

6.   Accountability of IBM Materials

     All IBM materials are and will remain the property of IBM. Synon agrees to
     maintain a one hundred (100%) percent accountability of all IBM
     Confidential materials at all times and will be prepared to locate and
     produce all such materials at any time.

     IBM, at its option, reserves the right to retrieve Product related IBM
     Confidential materials prior to termination of this Agreement, if the
     Product becomes generally available.

7.   Protection of IBM Assets







Agreement Number 985-0377

<PAGE>   53

Keith Jaeger

Page 3

     Synon shall maintain security procedures adequate to prevent loss of any
     IBM Confidential materials. If such a loss occurs, Synon shall notify IBM
     immediately.

     When not in use, IBM Confidential information will be secured or locked in
     a safe, file, desk, cabinet, or other suitable container or furniture, or
     in a locked room with restricted access. Items of work in process or work
     products that embody IBM Confidential information and which are impractical
     to secure or lock as required above will be completely covered from view.
     In instances where complete cover is impractical, IBM must concur in
     advance to the security measures taken. Synon agrees to segregate IBM
     Confidential information from the confidential information of others.

8.   Confidentiality of the Agreement

     Synon agrees not to disclose by way of advertisement, publication, or
     otherwise to any person other than employees of Synon, who have a need to
     know for purposes of performing this Agreement, the existence, nature,
     substance, or terms and conditions of this Agreement or of the relationship
     between the parties hereto without the prior written approval of IBM.
     However, Synon may disclose this entire Agreement on a confidential,
     need-to-know basis, to its accountants, attorneys, or financial
     institutions.

9.   Disclaimers

     Neither this Agreement nor any disclosure of IBM Confidential information
     grants you any license under any patents or copyrights.

     IBM PROVIDES IBM CONFIDENTIAL INFORMATION TO Synon ON AN "AS IS" BASIS
     WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF
     MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

     Neither party shall be liable for any lost revenue, lost profits or other
     consequential damages under any part of this Agreement even if advised of
     the possibility of such damages. Furthermore, IBM shall not be liable for
     any delays, losses or any other damages which may result from the
     furnishing of any equipment, documentation, programs or services under this
     Agreement, even if advised of the possibility of such damages.

     infringed by Synon's use of such IBM Confidential information.

     Notwithstanding any other provisions of this Agreement, neither party shall
     have the right to use the other party's name, trademark or trade name or
     other designation (including any contraction, abbreviation, or simulation
     of any of the forgoing), or to refer to this Agreement or the services
     performed hereunder directly or indirectly, in connection with any product,
     service, promotion or publication without the prior written approval of the
     other party.

     use its best efforts to obtain any required government documents and
     approvals prior to exporting any technical data disclosed to Synon or any
     product to which such data relate.

13.  Waiver of Breach/Severability

     a waiver of any prior, concurrent or subsequent breach of the same or any
     other provisions hereof, and no waiver shall be effective unless made in
     writing and signed by an authorized representative of the waiving party. In
     the event that any provision of this Agreement shall be found illegal or
     otherwise unenforceable, such provision shall be severed, the entire
     Agreement shall not fail on account thereof, and the balance of the
     Agreement shall continue in full force and effect.

PART 2           IBM'S RESPONSIBILITIES

2.1      IBM will:

         a)      review for approval the White Paper and Development Plan for 
                 functional content;

         b)      participate in scheduled checkpoints as per the agreed upon 
                 Development Plan; and

         c)      provide AS/400 technical assistance to you, where agreed upon 
                 by the Technical Coordinators.

PART 3           YOUR RESPONSIBILITIES

3.1      You will not begin work under this SOW until IBM Contract Coordinator 
         has issued you a purchase order.

3.2      You will prepare or provide the Deliverables identified in the Part 
         entitled Deliverables.

3.3      You will:

         a)      provide an early proof of concept for Obsydian and Synon/2E
                 inter/intranet enablement using a Java generator on the
                 AS/400. This proof of concept will include:

                 1)      a White Paper (Deliverable No. 1) which will document
                         the Obsydian and Synon/2E inter/intranet and Java
                         directions and high-level functionality on the AS/400.
                         You agree that the IBM contract coordinator must
                         approve any public release or dissemination of the
                         White Paper or any Derivative Works so as to avoid any
                         release of any IBM Confidential Information otherwise
                         protected under AECI #92-0016.;
                 
                 2)      a Development Plan (Deliverable No. 2) which will
                         include the necessary staffing, schedules and
                         checkpoints for implementing the functions described in
                         the White Paper;

                 3)      a functional alpha-level demonstration (Deliverable
                         Nos. 3, 4, 5, and 6);

                 4)      a Final Report (Deliverable No. 7) supplying IBM
                         feedback to understand implementation of Java
                         technology and where IBM can provide additional
                         features and functions to improve the implementation of
                         Java technology, and prioritizing prerequisite system
                         functions and features, such as: AS/400 Java execution
                         environment, AS/400 web-serving requirements, and
                         AS/400 development tool requirements. You agree that
                         all such feedback shall be owned by IBM and shall be
                         considered and treated as IBM Confidential Information
                         pursuant to AECT #92-0016.

IBM DEVELOPER AGREEMENT

BASE AGREEMENT

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

The IBM Developer Agreement ("IDA") consists of this Base Agreement and its
Transaction Documents. The IDA covers various transactions in which IBM may
involve you for:

         a)      providing Services;
         b)      developing IBM Materials; and
         c)      licensing other Deliverables.

A specific transaction will be defined by its own Transaction Document. Each
Transaction Document together with this Base Agreement forms a separate
agreement. The IDA is our complete agreement and replaces all prior oral, or
written communications between us regarding the transactions described in the
Transaction Documents.

By signing below for our companies, each of us agrees to the terms of this Base
Agreement. Once signed, 1) both parties agree any reproduction of the IDA made
by reliable means (for example, photocopy or facsimile) is an original unless
prohibited by local law and 2) all Deliverables and Services you provide are
subject to it.

PART 1.          DEFINITIONS

Capitalized terms in the IDA have the following meanings. A Transaction Document
may define additional terms. However, those terms apply only to that Transaction
Document.

1.l      APPEARANCE DESIGN is the appearance presented by an object, formed in 
         hardware or by software, that creates a visual impression on an
         observer. Appearance Design refers to ornamental and not the functional
         aspects of the object.

1.2      BACKGROUND MATERIALS are items 1) in which the copyrights are owned by 
         a third party or 2) that you prepared or had prepared outside the scope
         of the IDA. Background Materials are contained within a Deliverable.

PART 2.          AGREEMENT STRUCTURE

2.1      The IDA consists of:

         a)       this BASE AGREEMENT that defines the basic terms and
                  conditions of our relationship; and

         b)       TRANSACTION DOCUMENTS that specify the details of a
                  transaction and may include additional terms and conditions.
                  Transaction Documents include Statements of Work, Descriptions
                  of Licensed Work and Descriptions of Exclusive Marketing
                  Rights. Both parties accept the terms of the Transaction
                  Document and the identified exhibits, appendices and schedules
                  by signing the Transaction Document.

2.2      If there is a conflict among the terms of the documents, Transaction
         Document terms prevail over Base Agreement terms. Terms in IBM's
         purchase orders and your invoices are void unless identified otherwise
         in the IDA.

PART 3.          OUR RELATIONSHIP

3.1      Each party is an independent contractor. Neither party is, nor will
         claim to be, a legal representative, partner, franchisee, agent or
         employee of the other except as specifically stated in the IDA. Neither
         party will assume or create obligations for the other. Each party is
         responsible for the direction and compensation of its employees.

3.2      Each party may have similar agreements with others. Each party may
         design, develop, manufacture, acquire or market competitive products
         and services and conduct its business in whatever way it chooses
         provided there is no conflict with the IDA. IBM is not obligated to
         announce or market any products or services. IBM does not guarantee the
         success of its marketing efforts. IBM will independently establish
         prices for its products and services.

3.3      Both parties will maintain relevant records to support invoices issued
         or payments made to the other. The records will be retained and made
         available for three years from the date of the related payment or
         invoice. If one party requests, the other will make these records
         available to an independent auditor chosen and compensated by the
         requesting party. Each party's requests will be in writing and will not
         occur more than once each year. The auditor will sign a confidentiality
         agreement and will only disclose to the requesting party any amounts
         due and payable for the period examined.

3.4      The Transaction Document will identify coordinators that represent each
         party and where to send all notices which must be in writing, payments
         and deliveries. A party will provide notice to the other when
         coordinators change.

3.5      No Deliverable or Tool will contain your or any third party's
         confidential or proprietary information. Where confidential information
         must be exchanged, it will be done under a signed confidentiality
         agreement. Except for your preexisting, commercially available
         Deliverables, you will not disclose Deliverables to others without
         IBM's written approval.

3.6      You will not disclose the terms of the IDA to a third party except a)
         to your accountants, lawyers or other professional advisors under a
         confidentiality agreement or b) as required by law provided you get any
         confidential treatment for them which is available.

3.7      Neither party relies on any promises, inducements, representations made
         by the other or expectations of more business dealings except as
         expressly provided in the IDA. The IDA accurately states our business
         agreement.

3.8      IBM may lend you items for use in a transaction. If so, IBM will do so
         under a signed equipment and program loan agreement. You will not
         disclose the items to others without IBM's written approval.

3.9      IBM may evaluate each Deliverable before accepting it to verify that it
         meets the requirements of the IDA. IBM will advise you if it accepts
         (in whole or in part) or rejects each Deliverable. IBM will identify
         errors or deficiencies that it finds. You will either promptly correct
         the errors and deficiencies or obtain IBM's agreement on a plan to
         correct them within 10 working days after receiving notification. All
         corrections will be made at no charge to IBM. If you do not make the
         corrections, IBM may withhold payments due or require you to refund
         payments made to you.

3.10     You will:

         a)       perform Services and provide all Deliverables according to the
                  Transaction Document. You will have a process-driven approach

         g)       adequately train your employees to perform all work;

         h)       comply with the Exhibit. Activity on IBM's Premises when you

         11246 of the President of the United States on Equal Employment
         Opportunity and the Occupational Safety and Health Act of 1970.

         patent protection, IBM will prepare the patent application, unless
         agreed to otherwise. IBM will advise you of the status of the
         application and will consider your proposed comments and suggestions
         about it If either party decides not to equally share the costs of

                                   Page 5 of 8

IDA00A dated September 30, 1994             IBM Developer Agreement #RAL-960509
                                                         Dated December 13, 1996
<PAGE>   11

         a)       failure by you, not caused by IBM, to perform your obligations
                  under the IDA;

         b)       improper preparation or design of a Deliverable;

         c)       breach of your warranties and representations;

         d)       negligent or willful arts or omissions committed by you;

         e)       failure by you to comply with governmental laws and
                  regulations; or infringement by you or the Deliverables of
                  patents, copyrights, trademarks, trade secrets and other
                  intellectual property rights.

6.2      If such a claim appears likely or is made, you will promptly provide 
         IBM notice.  You will:

         a)       obtain the necessary rights for IBM, its Subsidiaries,
                  Distributors and their respective customers to continue to use
                  the Deliverables on an uninterrupted basis and exercise all
                  rights granted in the Deliverables; or

         b)       modify the Deliverables at your expense to resolve the claim.

         If you are not able to do either within a reasonable period of time,
         IBM may terminate the related Transaction Document for your breach.

6.3      You will pay any settlement amounts you authorize and all costs,
         damages and attorneys' fees that a court finally awards if IBM:

         awards. IBM's total liability for a transaction is limited to payments
         due to you for that transaction.

6.5      You are not liable for indemnification for infringements that result
         solely from complying with IBM's detailed instructions or

PART 7.          TERM AND TERMINATION

7.1      A Transaction Document specifies the effective date of a particular
         transaction. The Transaction Document continues until terminated or
         completed.

7.2      Either party may terminate a Transaction Document for the other's
         breach by providing a 30 day notice that describes the breach. The
         termination will not be effective if the breach is cured within the
         notice period. A breach of a Transaction Document for a Deliverable is
         considered a breach of all Transaction Documents involving that
         Deliverable.

         If IBM terminates a Transaction Document for your breach, you are
         liable for any costs incurred by IBM and other damages. In addition,
         IBM may require:

         a)       you to return advance payments and deliver work in progress to
                  IBM. IBM may complete the work and offset payments due by
                  IBM's completion costs and other damages. You will provide
                  reasonable training to IBM or its designees to enable
                  completion; or

         b)       you to reimburse IBM for all payments made to date plus any
                  reprocurement costs if IBM determines that it will not
                  complete the work.

7.3      Either party may, for its convenience, terminate this Base Agreement on
         30 days' notice. However, the Base Agreement will continue for
         Transaction Documents already in place until the Transaction Documents
         are terminated or completed.

                  per person / $500,000 per event for personal injury and
                  $200,000 per event for property damage.

         You remain liable for any damages above the stated minimums.

8.2      The insurance will provide that the insurer notify IBM at least 30 days
         before any non-renewal, cancellation or other material change in your
         coverage, You will name IBM as an additional insured under b) and c)
         above. You will provide IBM with a certificate of insurance as proof of
         this minimal coverage on request.

PART 9.                   PAYMENT

9.1      IBM will pay you for a transaction according to the IDA. All payments
         will be made in U.S. dollars. Your applicable taxes, expenses and
         payments to third parties are included in the compensation, unless
         identified otherwise in a Transaction Document.

9.2      You will invoice IBM for amounts due unless the Transaction Document
         states otherwise. You will submit invoices within 30 days after
         completion of work specified in a Transaction Document. IBM will pay
         you within 30 days of receiving your acceptable invoice. The
         Transaction Document will define the information required for your
         invoice.

9.3      If you offer another party lower rates, prices or royalties or
         equivalent Services or Deliverables during the term of the IDA, you
         will promptly offer the same to IBM.

PART 10.                  GENERAL

         successors or assigns. IBM may delegate its obligations to its
         Subsidiaries.

10.3     If any provision of the IDA is unenforceable at law, the rest of the
         provisions remain in effect. The headings in the IDA are for reference
         only. They wi11 not affect the meaning or interpretation of the IDA,

10.4     Neither party will bring a legal action against the other more than two
         years after the cause of action arose. This does not apply to actions
         brought to enforce Indemnification and Liability or intellectual

         disputes. Each party waives its rights to a jury trial in any resulting
         litigation. Litigation will only be commenced in the State of New York.

10.5     For a change to the IDA to be valid, both parties must sign it. No
         approval, consent or waiver will be enforceable unless signed by be
         granting party. Failure to insist on strict performance or to exercise
         a right when entitled does not prevent a party from doing so later for
         that breach or a future one.

10.6     You will submit to personal jurisdiction in any forum where IBM is sued
         for claims related to the IDA.

2.       APPOINTMENT OF DISTRIBUTOR: RELATIONSHIP BETWEEN THE PARTIES

2.1      GRANT OF DISTRIBUTION RIGHTS

         (a)     Synon hereby grants to the Distributor the non-exclusive right
                 to purchase (by way of licence) Products from Synon for sub-
                 licensing to End Users in the Territory, and the Distributor
                 agrees to so purchase the Products exclusively from Synon and
                 to support the Products, for the term set out in Clause 10 and
                 subject to and in accordance with the provisions of this
                 Agreement.

         (b)     The Distributor may appoint sales agents for the purpose of
                 obtaining orders of the Products on behalf of the Distributor
                 after receiving Synon's prior written consent thereto in
                 accordance with sub-Clause 13.1 hereof.

         (c)     The Distributor shall promptly inform Synon in writing, of
                 changes in its underlying ownership and structure at every
                 level and in particular of any proposed Change of Control.

2.2      EQUIVALENT PRODUCTS
         The Distributor warrants that neither it nor any of its Affiliates
         produces goods that are identical or equivalent to the Products.  The
         Distributor agrees that should it or any of its Affiliates undertake
         such production during the term of this Agreement or any renewal
         thereof, either through a start up venture or as a result of an
         acquisition or merger anywhere in the world, the Distributor shall
         promptly notify Synon of such undertaking and Synon shall have the
         right to immediately terminate this Agreement upon giving written
         notice to the Distributor.

2.3      PARALLEL IMPORTS
         The parties hereby acknowledge that nothing contained herein shall
         oblige Synon to take any actions to impede parallel imports of the
         Products into the Territory. Neither party shall make it difficult for
         wholesalers or other customers in the Territory to obtain the Products
         from other suppliers within the European Community (the "EC") or,
         insofar as no alternative source of supply is available from within
         the EC, from outside the EC.

2.4      RELATIONSHIP BETWEEN THE PARTIES
         The relationship between Synon and the Distributor under this
         Agreement is that of licensor and licensee.  Neither the Distributor
         nor its officers, employees or agents are or will be deemed to be the
         agents or representatives, legal or otherwise of Synon for any purpose
         whatsoever.  Neither the Distributor nor its officers, employees or
         agents, are granted by this Agreement, or otherwise, any express or
         implied right or authority (neither shall the Distributor nor its
         officers, employees or agents take any action which would have the
         effect of creating the appearance of such authority) to assume or
         create any obligation or responsibility on behalf of or in the name of
         Synon or to bind Synon in any manner whatsoever.  The Distributor, its
         officers, employees and

                                                                               4

         Synon when (a) endeavouring to make sales of Products under the terms
         of this Agreement, (b) supporting Products, (c) executing Licence
         Agreements with customers (d) dealing with employees or third parties
         (e) executing Maintenance Agreements or (f) undertaking any other
         activity, related or unrelated to this Agreement.  The Distributor
         agrees to adopt such descriptive titles in the Territory as are
         acceptable to Synon to convey to the public the limited rights
         conferred upon the Distributor by this Agreement.

2.5      CAPACITY
         The Distributor warrants that it is legally qualified and authorised
         in the Territory to market, license and support the Products as
         contemplated by this Agreement.

3.       UNDERTAKINGS OF SYNON

3.1      DUTIES OF SYNON
         Synon agrees to provide to the Distributor, from Synon's executive
         offices the following materials and technical support services, which

         (a)     the number of Products ordered by the Distributor pursuant to
                 this Agreement;

                 required by Licence Agreements, or customers as required by
                 Maintenance Agreements, entered into with respect to the
                 Territory or one copy thereof for copying by the Distributor
                 solely for distribution to Licensees and customers in
                 accordance with the terms of Licence Agreements and
                 Maintenance Agreements, as aforesaid;

         (c)     copies of all relevant promotional materials that Synon
                 develops from time to time to assist the Distributor in

         (d)     the training of the Distributor's employees who will be
                 responsible for training the Distributor's sales and technical
                 support personnel; and

         (e)     reasonable "second level" technical consultation and advice to
                 the Distributor's technical employees concerning the
                 installation and operation of the Products, including, but not
                 limited to, identification and resolution of Product "bugs".

3.2      STANDARD OF PERFORMANCE
         Synon agrees to use its reasonable endeavours to provide the
         Distributor with the materials and technical support services
         described in sub-Clause 3.1.

3.3      PRODUCT WARRANTY AND LIABILITY

         (a)     Synon warrants to the Distributor that, at the time of
                 delivery to the Distributor and for ninety days thereafter,
                 each Product, Product fix, Product enhancement and new Product
                 release shall be free from defects in workmanship and
                 materials and shall perform substantially in accordance with
                 applicable product specifications.  The Distributor's remedy
                 with respect to any breach of this Product warranty shall be
                 limited to the prompt repair or replacement of such item at
                 Synon's expense.  The repair or replacement of any such
                 Product is conditional on the Distributor giving prompt notice
                 to Synon of any such fault, together with full information and
                 fully documented examples thereof and the fault not being
                 attributable to a malfunction of equipment or software other
                 than the Products.  The foregoing product warranty is in lieu
                 of all other warranties, written or oral, express or implied
                 (which are hereby excluded), including, but without limitation
                 of the generality of the foregoing, the implied warranties of
                 merchantability and fitness for a particular purpose, whether
                 imposed by contract, statute, course of dealing, custom or
                 usage or otherwise.  The remedies under this warranty are
                 exclusive and Synon neither assumes nor authorises anyone to
                 assume for it any other obligation.

         (b)     Except as specified in this sub-Clause 3.3 Synon shall not be
                 liable to the Distributor (or to any Licensee or End User) in
                 contract, tort, negligence or otherwise for any loss or damage
                 that may arise in connection with the delivery, installation,
                 use or performance of the Products, in excess of the amount
                 paid therefore by the Distributor.

         (c)     In no event shall Synon suffer any liability in contract,
                 tort, negligence or otherwise arising out of or in connection
                 with this Agreement, for any indirect, special, incidental,
                 economic or consequential loss or damage, including, without
                 limitation to the generality of the foregoing loss of profits,
                 business, contracts or anticipated savings even if Synon has
                 been advised of the possibility thereof.

                                                                               5
<PAGE>   6
         (d)     The above warranty shall constitute the sole remedy of the
                 Distributor and the sole liability of Synon whatsoever, and
                 the Distributor hereby waives all other remedies, warranties,
                 guarantees, causes of action or claims, express or implied,
                 arising by law or otherwise against Synon.  Nothing in this
                 Agreement seeks to or does exclude or limit the liability of
                 Synon for death or personal injury arising from its
                 negligence.

         (e)     Synon shall in no event be responsible or liable for
                 modifications made to the Products, or any of them, by the
                 Distributor or others, or for damage caused thereto by
                 negligence, accident or improper use or installation by the
                 Distributor or others.

         (f)     Each paragraph and provision of this sub-Clause 3.3 excluding
                 or limiting liability shall be construed separately,
                 continuing and surviving even if for any reason one or other
                 of those paragraphs or provisions is held inapplicable or
                 unenforceable in any circumstances and shall remain in force
                 notwithstanding the termination or expiration of this
                 Agreement.

3.4      INFRINGEMENT INDEMNITY
         Synon agrees to indemnify and hold the Distributor harmless from any
         final award of costs and damages against a Licensee for any action
         based on infringement of any patent right or copyright as a result of
         the use of the Products under the terms and conditions specified in
         the Licence Agreement and under normal use; Provided that Synon is
         promptly notified in writing of any such suit or claim against the
         Distributor (to which the Distributor shall not make any admission)
         and Further Provided that the Distributor permits Synon to defend,
         compromise or settle the same and gives Synon all available
         information, assistance and authority to enable Synon to do so.  The
         foregoing states the entire liability of Synon with respect to
         infringements of any copyrights or patents by the Products or any part
         thereof.

                 the installation and operation of the Products and the

                 respect of the immediately following year the distributor
                 shall submit to Synon for Synon's approval a proposed
                 marketing plan including a forecast of sales for the
                 immediately following calendar year.

                                                                               6

                 distributor, representative, agent or consultant) or as a
                 partner, joint venture or shareholder (other than as a
                 beneficial holder of not more than 5% of the voting shares or
                 stock of a publicly traded company) in another entity, engage

                 employees of the Distributor in their sale and/or service
                 Products.  If Synon provides such training courses, the
                 Distributor shall require its personnel performing functions
                 covered by any training course to attend the said courses.
                 All costs or expenses incurred by the Distributor in attending
                 or participating in such training courses shall be for the

         (f)     Sales Quotas
                 The Distributor confirms that during the term of this
                 Agreement, it will use its best endeavours to ensure that the

                 performance of this Agreement at all distributor sales
                 meetings held by Synon of which it is notified.  The
                 Distributor shall not be obliged to send a delegate to such
                 sales meetings more than once a quarter.


                                                                               7

                 The Distributor shall produce education, advertising and sales
                 literature and brochures promoting the Products in the
                 Territory.  All such promotional material shall be disclosed
                 to Synon for its approval prior to publication.  The
                 Distributor shall make such amendments, inclusions, deletions
                 and variations thereto as Synon shall reasonably request and

5.       PRODUCT ORDERS

5.1      LIMITATION OF LIABILITY ETC.

         (a)     The parties hereby agree that Synon shall not have any
                 liability to Distributor or to any third party for any
                 compensation, damages, penalties or otherwise in the event
                 that the Distributor shall fail to submit a quotation,
                 proposal or tender to an End User, or after submission thereof
                 withdraws such quotation, proposal or tender, or shall refuse

                 deliver a Product in accordance with an End User's order and a
                 Licence Agreement.

         (b)     The Distributor agrees not to make the Products available to
                 any End User unless and until such End User shall have
                 executed and delivered to the Distributor a signed Licence
                 Agreement and details thereof have been given to Synon.

         (c)     The Distributor agrees not to provide or procure the provision
                 of any maintenance services (including the provision of

         Synon shall not bear any liability resulting from any delay in the
         delivery of a Product or any user manuals to the Distributor or to any
         End User or Licensee.  Risk of loss or of damage to the Products shall
         pass to the Distributor when such Products are delivered to the
         Distributor's place of business or to such other address in the
         Territory as the Distributor shall request delivery to.  The
         Distributor shall then pack the Products for despatch and arrange for
         such despatch (at the Distributor's cost) to Licensees.  The
         Distributor shall insure the Products and the user manuals whilst
         under its control including transit to the Licensee.

5.3      TAXES AND OTHER CHARGES
         The Distributor agrees to pay, collect and remit all value-added,

         without limitation to the generality of the foregoing, import duties,
         border taxes, brokerage fees, and other import charges or expenses,
         imposed in the Territory in respect of the Products (other than income
         taxes imposed directly on Synon in the Territory).  The Distributor
         further agrees to indemnify and hold Synon harmless against any such
         liabilities.  In addition the Distributor shall provide to Synon all
         relevant withholding tax certificates within thirty (30) days of
         either payment of any sum due to Synon hereunder or the Distributor's
         receipt of such certificate from the appropriate revenue authority (if
         later).  The provisions of this sub-Clause 5.3 and sub-Clause 5.5
         shall survive termination or expiration of this Agreement.

5.4      CUSTOMS AND OTHER CLEARANCES
         The Distributor agrees to obtain at its expense all necessary customs,
         import and other governmental authorisations and approvals in the
         Territory relating to this Agreement (including, without limitation to
         the generality of the foregoing, foreign exchange, foreign investment
         and transfer of technology approvals and notifications).  Synon's
         obligations under this Agreement shall be specifically subject to the
         grant and effectiveness of all necessary authorisations and approvals.

5.5      EXPORT REQUIREMENTS
                                                                               8

         available the Products to any third party for use outside the
         Territory, or to make the Products available to any third party within
         the Territory, if the Distributor knows, or has reasonable grounds to
         suspect, that such third party is planning to use or otherwise
         transfer the Products outside of the Territory in violation of such
         export laws, regulations or orders or in violation of any Licence
         Agreement.

5.6      NO WARRANTY OF CONTINUED AVAILABILITY
         Synon does not represent or guarantee to the Distributor the continued
         availability for sale of any of the Products and assumes no liability
         in connection with any loss or damage to the Distributor, arising out
         of Synon's failure to accept or fill orders of the Products due to
         their unavailability.  Synon at its sole discretion, may at any time,
         change any Product or withdraw any Product from its current list of
         Products or limit available quantities of any product, or Products, or
         remove or add to the list of Products which the Distributor is
         authorised hereunder to distribute and support.  If Synon removes from
         the list of Products set out in Appendix A, it shall give ninety (90)
         days written notice thereof to the Distributor.

6.       PRODUCT LICENSES

6.1      USE OF LICENCE AGREEMENTS
         The Distributor agrees to license the Products to End Users in the

         (a)     Subject to the Distributor's compliance with the provisions of
                 this Sub-Clause 6.3 the Distributor may at its expense and
                 subject to Synon's prior written approval, translate the
                 Licence Agreement and/or the Maintenance Agreement into such
                 languages as may be necessary or desirable for its use in the
                 Territory and to make such modifications as may be necessary
                 or desirable to conform such agreement to customary commercial
                 practices in the Territory (as reflected in licence agreements
                 or maintenance agreements (as the case may be) commonly used
                 in the Territory for similar computer software products).

         (b)     No such translation or modification shall (i) diminish or
                 limit any of Synon's rights (proprietary or otherwise) in the
                 Products, (ii) diminish or limit the enforceability of such
                 rights, (iii) convey any rights of ownership in the Products,
                 (iv) permit the use or copying of the Products except for the
                 limited purposes permitted under the Licence Agreement, (v)
                 permit disclosure of any proprietary information regarding the
                 Products or (vi) permit reverse-engineering, disassembly or
                 decompilation of the Products.

         (c)     The Distributor agrees (i) to provide to Synon upon Synon's
                 request, for review by Synon and its legal advisers copies of
                 any such translated or modified version of the Licence
                 Agreement and the Maintenance Agreement and copies of the
                 literal English translations thereof and (ii) to obtain
                 Synon's written approval thereof prior to providing copies
                 thereof to any End User or Licensee.

         (d)     In the event that any legislation or judicial or
                 administrative action in the Territory renders any provision
                 of a Licence Agreement or a Maintenance Agreement invalid or
                 unenforceable, the Distributor agrees to so notify Synon in
                 writing, and to assist Synon in appropriately modifying such
                 agreement.  The provisions of this paragraph shall survive
                 termination or expiration of this Agreement.

6.4      ENFORCEMENT OF LICENCE AND MAINTENANCE AGREEMENTS
         The Distributor agrees to use its best endeavours to enforce each
         Licence Agreement and each Maintenance Agreement to the full extent of
         applicable law and to safeguard all rights (proprietary or otherwise)
         and interests of Synon in the Products.  The Distributor agrees to
         notify Synon in a timely manner of any legal notices serviced on, or
         legal actions brought against, the Distributor concerning the Products
         or the Distributor's performance of its duties hereunder.  The
         Distributor agrees not to institute any legal action or other
         proceedings with respect to a Licence Agreement or a Maintenance
         Agreement or the Products (or to enter into any compromise in respect
         thereof) without the prior written consent of Synon.  The provisions
         of this sub-Clause 6.4 shall survive termination or expiration of this
         Agreement.

                                                                               9

7.       PRICE, PAYMENT AND REPORTS

7.1      PRICE AND PAYMENT

         (a)     Synon agrees to supply a demonstration and training version of
                 each of the Products to the Distributor (in accordance with
                 sub-Clause 4.1(h)) at no charge to supply all other copies of
                 the Products to the Distributor at the prices specified in
                 Appendix A Part II paragraph (a) (as varied from time to
                 time).

         (b)     The Distributor shall pay to Synon commission of all Licence
                 Agreements and Maintenance Agreements calculated in accordance
                 with Part II, of Appendix A.

         (c)     The prices and commission (including the percentage
                 calculation) specified in Appendix A may be changed by Synon
                 from time to time upon giving not less than ninety (90) days
                 prior written notice to the Distributor.  All prices are
                 exclusive of customers charges, fees and applicable taxes
                 which shall be paid in addition.

         (d)     The Distributor shall pay to Synon all amounts due under this
                 Clause 7 not later than the twenty eighth (28th) day of the
                 second calendar month following the calendar month in which
                 the Distributor is invoiced for payment whether or not the
                 Distributor has received payment from Licensees.  Payment
                 shall be deemed to be made pursuant to this Clause 7 on actual
                 receipt of the monies due into Synon's bank account and not
                 before.  For example, a sale with an invoice date 31 December
                 will be due for payment on 28 February.

         (e)     All amounts payable by the Distributor pursuant to this Clause
                 7 shall be paid to Synon directly to such bank account as
                 Synon may designate and shall be paid in sterling (or in such
                 other currency as Synon may specify in writing from time to
                 time).  Any sum due to Synon hereunder and not paid on the due
                 date for payment shall bear interest at the rate of five per
                 cent above the base lending rate of Midland Bank plc (or such
                 other UK Clearing bank as Synon may specify) from time to
                 time, or the maximum rate otherwise permitted by applicable
                 law, which ever shall be the lower, from the date such sum
                 falls due for payment until the date payment is received by
                 Synon, and shall be compounded at half yearly intervals.

         (f)     In the event that the central bank or similar governing body
                 in the Territory shall impose any restrictions preventing
                 payment of funds due to Synon in accordance with this Clause
                 7, and the Distributor shall not otherwise remit such amounts
                 to Synon, Synon may, in its discretion, terminate this
                 Agreement pursuant to sub-Clause 10.2(f) and may instruct the
                 Distributor to deposit such funds in a specified account of
                 Synon in a banking institution located in the Territory.

         (g)     Notwithstanding any provision of this Agreement, in the event
                 that the Distributor shall fail to pay all amounts due to
                 Synon hereunder within the time specified in sub-Clause 7.1(d)
                 on two consecutive occasions, Synon shall have the right to
                 terminate this Agreement in accordance with sub-Clause 10.2(h)
                 as a material breach.  The parties hereby agree that such
                 action of non- payment by the Distributor would be a material
                 breach of this Agreement.

         (h)     Synon reserves the right to off-set any outstanding amounts
                 due to the Distributor hereunder against any amounts due from
                 the Distributor hereunder or arising from any breach by the
                 Distributor of its duties and obligation hereunder.  The
                 provisions of this sub-Clause 7.1 shall survive termination or
                 expiration of this Agreement.

7.2      MONTHLY REPORTS
         On the first working day of each calendar month the Distributor agrees
         to transmit Synon by telefax a properly completed sales report in a
         form supplied by Synon from time to time setting forth such
         information concerning the licensing of the Products and names of
         Licensees as Synon may request and including a six monthly sales
         forecast.  Such sales reports shall set out what the Distributor
         believes to be the number of Licence Agreements and Maintenance
         Agreements to be signed up during that six month period.  The type of
         information required by Synon for completion by the distributor is set
         out at Appendix D, and is subject to variation and change by Synon
         from time to time.  The Distributor shall use its best endeavours to
         ensure the accuracy of the information given to Synon in each of these
         reports.

7.3      ACCOUNTS
         The Distributor shall provide to Synon each year a copy of its audited
         annual accounts within one month of the audit report being signed by
         its auditors.  If the Distributor does not have audited accounts it
         shall in each 12 month period from the date of this Agreement supply
         to Synon a copy of the management accounts it does have for the
         previous 12 month period, and the Distributor shall ensure that such
         accounts shall represent a true and fair view of the Distributor's
         business.

                                                                              10
<PAGE>   11
7.4      REFERENCES
         The Distributor hereby authorises Synon to apply to any of its banks,
         (as Synon shall decide from time to time), to obtain references in
         respect of the financial standing of the Distributor.  The Distributor
         shall give written notice to Synon as soon as it changes any bank with
         whom it does business.

7.5      REVIEW OF RECORDS
         Synon shall have the right at any time during the term of this
         Agreement, directly or through an independent third party, upon thirty
         (30) days' prior written notice to the Distributor, to conduct a
         review at the Distributor's principal business offices of the
         Distributor's books and records relating hereto and to make copies
         thereof at Synon's expense.  If the results of such a review shall
         disclose a deficiency in amounts payable by the Distributor to Synon
         in excess of five percent (5%) of the amounts actually paid or
         reported as being payable to Synon hereunder for any period which is
         so reviewed, then the Distributor shall promptly reimburse Synon for
         the entire cost of such review, including, but not limited to,
         professional fees and travel and lodging expenses.  The provisions of
         this sub-Clause 7.5 shall survive for the period of twelve (12) months
         following termination or expiration of this Agreement.

7.6      LETTER OF CREDIT
         Synon reserves the right, at any time during the term of this
         Agreement, to request that the Distributor provide an open letter of
         credit to Synon in respect of maximum estimated sums due to Synon
         hereunder during the immediately following twelve (12) month period
         and thereafter for each consecutive twelve (12) month period of this
         Agreement (or part thereof).  The Distributor shall, within ten (10)
         days of receiving such request in writing procure, at its cost, the
         provision of such letter of credit from such bank as Synon shall
         specify (acting reasonably) and for such sum as Synon shall specify,
         (acting reasonably), to be a predetermined estimate of maximum sums
         due to it hereunder during that immediately following twelve (12)
         month term (or part thereof as the case may be).

8.       TRADE SECRETS AND PROPRIETARY INFORMATION

8.1      PROPRIETARY NAME OF PRODUCTS

         (a)     The Distributor acknowledges that the Products are proprietary
                 in nature, that Synon owns all trade secret, copyright,
                 trademark and patent rights granted by law therein, and that
                 Synon neither grants nor otherwise transfers any rights of
                 ownership therein to the Distributor.  The Distributor agrees
                 not to duplicate or otherwise reproduce any Product or any
                 Documentation in whole or in part save as authorised in
                 writing by Synon for distribution pursuant to Licence
                 Agreements or Maintenance Agreements.  The Distributor further
                 agrees to take all reasonable steps to ensure that no
                 unauthorised persons shall have access to any of the Products
                 and that all authorised personal having access to the Products
                 shall refrain from any such disclosure, duplication or
                 reproduction except to the extent reasonably required in the
                 performance of the Distributor duties under this Agreement.
                 All officers, employees and agents of the Distributor having
                 access to any of the Products must be subject to nondisclosure
                 or similar agreements consistent with the Distributor's
                 obligations hereunder, which the Distributor agrees to enforce
                 to the full extent of applicable law.  If, pursuant to this
                 Agreement, the Distributor does copy the Products or the
                 Documentation it shall ensure that all proprietary notices of
                 Synon are shown on such copies.

         (b)     The Distributor shall not, directly or indirectly, register,
                 apply for registration or attempt to acquire any legal
                 protection for the Products or any proprietary rights therein
                 in its own name or take any other action which may adversely
                 affect Synon's right, title or interest in or to the Products.

         (c)     The Distributor shall promptly notify Synon as soon as it
                 becomes aware of any breach by any third party of any of
                 Synon's intellectual property rights in any of the Products or
                 the Documentation or any unauthorised use of any of the
                 Products.

         (d)     In the event of a breach by the Distributor or any of its
                 officers, employees or agents of its or their obligations
                 under this Clause 8 or if the Distributor at any time
                 challenges, directly or indirectly, the right, title or
                 interest of Synon in and to any of the Products or the
                 validity or enforceability of Synon's claimed rights therein
                 under applicable law Synon may immediately terminate this
                 Agreement without liability to the Distributor by giving
                 written notice to the Distributor.  In addition Synon may
                 bring an appropriate legal action in respect of any such
                 breach or challenge (as the case maybe), and shall be entitled
                 to recover from the Distributor its legal fees and costs in
                 addition to other appropriate relief.

                                                                              11

8.2      NO PRODUCT MODIFICATIONS
         The Distributor shall not have the right under this Agreement or
         otherwise to receive the source code to any of the Products.  The
         Distributor agrees not to modify or alter, or attempt to modify or
         alter, any of the Products or the Documentation without the prior
         written authorisation of Synon.  In the event that the Distributor
         makes any modification or alteration, the Distributor shall promptly
         deliver and assign the same to Synon and the Product or Documentation
         as modified or altered shall be and shall remain the sole and
         exclusive property of Synon but Synon shall thereupon grant a
         non-exclusive licence to the Distributor for it to use the
         modification or alteration for the purposes of its business.

8.3      CONFIDENTIAL INFORMATION
         The parties agree that all information furnished by Synon to the
         Distributor hereunder, in whatever form, except promotional and
         advertising material, is Confidential Information.  The Distributor
         agrees that it will use all Confidential Information disclosed to it
         by Synon only in furtherance of its performance hereunder, and for no
         other purpose.  Except as provided above, the Distributor agrees that
         it will not disclose Confidential Information to any other person or
         entity without the express prior written consent of Synon.  The
         Distributor agrees that it will protect the confidentiality of
         Confidential Information with the same degree of care with which it
         protects its own Confidential Information.

8.4      OWNERSHIP OF CONFIDENTIAL INFORMATION
         All Confidential Information furnished to the Distributor hereunder
         (including all copies thereof) is and shall remain the property of
         Synon and shall be returned to or otherwise disposed of as instructed
         by Synon promptly upon demand or upon the termination or expiration of
         this Agreement.

8.5      The provisions of this Clause 8 shall survive termination or
         expiration of this Agreement.

9.       USE OF TRADE NAMES AND TRADEMARKS

9.1      SCOPE OF USE

         (a)     The Distributor hereby acknowledges the validity and Synon's
                 ownership of Synon's Trademarks throughout the world, whether
                 or not registered.  The Distributor further acknowledges that,
                 except as provided herein or as otherwise expressly provided
                 in writing, (i) it has no rights or interest of any kind in or
                 to Synon's Trademarks, including, without limitation to the
                 generality of the foregoing, the name "SYNON/2", (ii) it shall
                 acquire no rights or interest therein by virtue of this
                 Agreement or the performance by the Distributor of its duties
                 and obligations hereunder, and (iii) it will not assert any
                 rights or interests therein by virtue of the rights granted to
                 the Distributor hereunder.  The provisions of this paragraph
                 shall survive termination or expiration of this Agreement.

         (b)     Synon hereby grants to the Distributor during the term of this
                 Agreement the non-exclusive, limited right to use the
                 proprietary Product names and marks in marketing the Products
                 in the Territory pursuant to this Agreement.  All rights
                 arising from such use by the Distributor shall inure to Synon.
                 Notwithstanding the foregoing, the Distributor shall be
                 prohibited from using the name "SYNON", any of the Product
                 names or marks, or any confusingly similar name or symbol, in
                 whole or in part with any products other than the Products.
                 Synon makes no warranty, express or implied, as to the use or
                 validity of such marks.

         (c)     The Distributor shall identify Synon as the owner of the
                 Trademarks in all Documentation and Product advertising and it
                 shall specify (in such form as Synon shall approve).  Products
                 are licensed products of Synon.  Synon reserves the right to
                 approve all advertising and marketing materials of the
                 Distributor, inter alia, to ensure the proper use of the
                 Trademarks.  The Distributor's rights hereunder shall continue
                 only during the term of this Agreement and, upon termination
                 or expiration of this Agreement, the Distributor shall cease
                 to use such Product names or any marks or variants sounding
                 like or appearing to be similar thereto.

         (d)     The Distributor shall not remove, alter or obliterate, or
                 cause to be removed, altered or obliterated, any trademarks,
                 trade names, copyright or other symbols placed upon Products
                 or Documentation delivered to the Distributor, provided,
                 however, that the Distributor may apply its own name and
                 address to the packaging of the Products.

9.2      PROTECTION AGAINST INFRINGEMENT

         (a)     The Distributor agrees to inform Synon promptly of all legal
                 requirements for protecting the proprietary rights of Synon in
                 and to the Products in the Territory, and agrees to cooperate
                 fully with Synon in protecting the Products from infringement.

                                                                              12
<PAGE>   13
         (b)     The Distributor agrees to report to Synon any known uses by
                 third parties in the Territory of marks or trade or product
                 names similar to the marks and trade and product names of
                 Synon.  The Distributor agrees to assist Synon in enforcing or
                 obtaining protection of such items in the Territory and
                 acknowledges that Synon shall have the sole right to bring a
                 legal action or suit for infringement thereof.
         (c)     The provisions of this sub-Clause 9.2 shall survive
                 termination or expiration of this Agreement.  
                 
9.3      REGISTRATION OF TRADEMARKS
         Unless prior registration of any Trademark is required by the laws of
         the Territory as a prerequisite for importation of the Products, Synon
         reserves the right to decide where and when to apply for the
         registration of the Trademarks in the Territory.  Any trademark
         registration shall be in the name and for the benefit and the account
         of Synon.

                 business or substantially the whole of its business;

         (d)     forthwith on notice to the Distributor if it shall have a
                 receiver or an administrative receiver appointed to its
                 undertaking or any of its assets or shall become subject to an
                 administration order or shall enter into liquidation whether
                 compulsory or voluntary or pass a resolution for its
                 winding-up (other than for the purpose of a bona fide scheme
                 of solvent amalgamation or reconstruction where the resulting
                 entity assumes all of the obligations of the Distributor), or
                 shall, if an individual be made or declared bankrupt or commit
                 any act of bankruptcy (of if a partnership any one of the
                 partners shall commit such an act) or shall be the subject of
                 any equivalent or similar or analogous provision or
                 arrangement or appointment or any analogous step is taken in
                 connection with the Distributor's insolvency, bankruptcy or
                 dissolution, applicable to the laws and regulations in the
                 Territory, or the country in which the Distributor is
                 incorporated or established or carries on business;

         (e)     there is a Change of Control of the Distributor;

                 imposes a restriction preventing the Distributor from making
                 payment of funds payable to Synon hereunder for a period in
                 excess of three (3) months;

         (g)     forthwith on notice to the Distributor if it assigns or
                 transfers the Agreement, or any of its rights or obligations

                 prior written consent;

         (h)     forthwith on notice to the Distributor if it breaches any
                 provision of this Agreement that Synon considers to be
                 material (acting reasonably in all the circumstances);

         (i)     in accordance with sub-Clauses 8.1(d) and 2.2

         (a)     In the event of the termination of this Agreement, whether by
                 the expiration of the original or any extended term hereof or
                 otherwise, the Distributor agrees promptly (i) to provide
                 Synon with all

                                                                              13
<PAGE>   14
                 outstanding reports and payments due to Synon pursuant to
                 Clause 7 or otherwise pursuant to this Agreement, (ii) cease
                 holding itself out as having any connection with Synon or the
                 Products (other than as provided in paragraph (b) below);
                 (iii) in the event of termination pursuant to sub-Clause
                 10.2(b), (c) or (d) to assign, and do all that is necessary to
                 procure the assignment, to Synon or as it may direct all
                 Licence Agreements and Maintenance Agreements and (iv) to
                 report to Synon in reasonable detail the status of all
                 discussions and negotiations with End Users and all services
                 which the Distributor is obliged to provide to such End Users
                 and Licensees with respect to the Products.

         (b)     Subject to paragraph a) above in respect to Maintenance
                 Agreements already entered at the date of termination or
                 expiration of this Agreement the Distributor shall continue to
                 provide maintenance services in accordance with this Agreement
                 until the expiration of the then existing term of the
                 Maintenance Agreement.  At the end of each such Maintenance
                 Agreement the provisions of this sub-Clause 10.3 shall apply
                 in respect of the Products the subject of the Maintenance
                 Agreement.

         (c)     In the event of expiration or termination hereof, all of the
                 Distributor's rights hereunder to promote, distribute and
                 support the Products, and to use the Product names and
                 identifying marks, shall automatically terminate and the
                 Distributor shall cease any use thereof (save as may be agreed
                 in writing with Synon for the purpose of the Distributor
                 complying with paragraph (b) hereof).  The Distributor agrees
                 to return to Synon all Products, marketing materials and other
                 information of Synon in any form (proprietary or otherwise) in
                 the Distributor's possession or under its control or, with the
                 prior written consent of Synon, to destroy the same, and in
                 either case to certify in writing to Synon that such actions
                 have been taken.

         (d)     Following the effective date of termination or expiration of
                 this Agreement the Distributor shall remit forthwith Synon all
                 sums due to it herein.  In the vent that the Distributor shall
                 fail to assign to Synon or as it may direct all Licence
                 Agreements immediately following such termination date (in the
                 even of termination being pursuant to sub-Clauses 10.2(b), (c)
                 or (d), Synon shall (directly or through its authorised
                 representatives), (i) be entitled to deal with such End Users
                 and Licensees, and (ii) be subrogated to the Distributor under
                 all Licence Agreements.

         (e)     In connection with any termination of this Agreement, the
                 parties agree to cooperate fully and to provide promptly all
                 information necessary or useful relating hereto.  At any time
                 for twelve (12) months following the termination or expiration
                 of this Agreement Synon shall have the right, directly or
                 through an authorised representative, to review the books and
                 records of the Distributor (including prospect records)
                 relating to this Agreement and to make copies thereof at
                 Synon's expense.  If the results of such review shall disclose
                 a deficiency in amounts payable by the Distributor to Synon in
                 excess of five per cent (5%) of the amounts actually paid or
                 reported as being payable to Synon hereunder for any period so
                 reviewed then the Distributor shall promptly reimburse Synon
                 for the entire cost of such review in accordance with
                 sub-Clause 7.5.

         (f)     The provisions of this sub-Clause 10.3 and the sub-Clause 10.5
                 shall survive termination or expiration of this Agreement.

10.4     CONTINUING OBLIGATIONS
         Expiration of the original or any extended or renewed term hereof or
         any other termination of this Agreement shall be without prejudice to
         any rights or obligations of the parties hereto which have accrued
         prior to such expiry or termination and shall not affect any provision
         of this Agreement which is expressly or by implication provided to
         come into effect on or to continue after such expiry or termination.

10.5     LIABILITY ON TERMINATION
         Synon shall not be liable to the Distributor, as a result of any
         termination of this Agreement, with or without cause, and shall not
         otherwise have any obligation (statutory or otherwise) to compensate
         or reimburse the Distributor for any claims or damages whatsoever
         (including, but not limited to, termination indemnities, lost revenues
         or profits, the Distributor's expenditures, investments, leasehold or
         employment obligations or other continuing commitments of the
         Distributor).  The Distributor specifically (i) waives all
         compensation and damages, whether direct, consequential or otherwise,
         to which it may otherwise have a right under applicable law in the
         Territory; (ii) agrees to indemnify and hold Synon harmless from and
         against all claims of the employees and agents of the Distributor for
         compensation or severance, disability, social security or similar
         payments; and (iii) agrees not to register as the agent or distributor
         of Synon in any jurisdiction within the Territory without the prior
         written consent of Synon.

                                                                              14

10.6     GOODWILL
         The Distributor acknowledges and agrees that any and all goodwill
         associated with the promotion, distribution and support of the
         Products in the Territory shall accrue directly to the benefit of
         Synon and shall be the sole and exclusive property of Synon.

11.      INDEMNIFICATION
         The Distributor shall indemnify and hold Synon and its Affiliates
         harmless from and against any and all claims, liability, costs and
         expenses (including legal fees) arising out of (a) the improper
         installation, support or maintenance of the Products by the
         Distributor or its employees, (b) any misrepresentations by the
         Distributor or its employees in respect of the Products, (c) any
         breach by the Distributor of any of the provisions of this Agreement
         or (d) any negligent, wrongful or intentional acts or omissions on the
         part of Distributor or its employees.  The provisions of this Clause
         11 shall survive termination or expiration of this Agreement.

12.      FORCE MAJEURE

12.1     Neither Synon nor the Distributor shall be liable for failure to
         perform any obligation under this Agreement if the failure is caused
         by war, insurrection, riot, fire, explosion, flood, strike, lock-out,
         injunction, inability to obtain fuel, power, raw materials, labour,
         containers or transportation, accident, malfunction of machinery or
         apparatus, national defence requirements, acts or regulations or
         national or local governments, denial of export or import licenses, or
         act of God, or any other cause beyond the control of the party.

12.      Notwithstanding the foregoing, the occurrence of a force majeure event
         or condition described in sub-Clause amounts then due and owing to
         Synon pursuant to the terms of this Agreement.

12.3     The Party claiming relief pursuant to sub-Clause 12.1 shall promptly
         notify the other Party in writing of the facts indicating the
         existence of any force majeure event or condition and the relief
         claimed.  The Parties agree to use all reasonable endeavours to
         overcome such conditions.  Sub-Clause 12.1 shall not relieve any Party
         of its obligation to perform its part of this Agreement at such time
         and to such extent as may be possible subsequent to the occurrence of
         the events or conditions described in sub-Clause 12.1 and within
         reasonable time thereafter.  Should such event or conditions continue
         unabated despite the parties' reasonable endeavours to overcome them
         for three (3) months from the date of notice given pursuant hereto,
         then the party receiving such notice shall have the option to
         terminate this Agreement without liability to the other party for the
         consequences of such termination by giving written notice.

13.      GENERAL PROVISIONS

13.3     NO IMPLIED WAIVERS
         The failure of either party to exercise any right or option it is
         granted herein, or to require their performance by the other party
         hereto of any provision of this Agreement, shall not prevent a
         subsequent exercise or enforcement of such provisions or be deemed a
         waiver of any subsequent breach of the same or any other provision of
         this Agreement.

13.4     MODIFICATION OR AMENDMENT
         Except to the extent and in the manner specified in this Agreement,
         any modification or amendment of any provision of this Agreement must
         be in writing and bear the signature of the duly authorised
         representatives of both parties.

13.5     LANGUAGE
         The language of this Agreement is expressly stipulated to be the
         English language.  In the event that this Agreement shall be
         translated into one or more other languages, the English language
         version of this Agreement shall be the governing version for purposes
         of interpreting and enforcing this Agreement.  All Products,
         Documentation and technical assistance to be provided hereunder by
         Synon shall be in the English language unless otherwise agreed between
         the parties.  In the event that the applicable law of the Territory
         shall require this Agreement to be governed by such law or shall
         require any of the foregoing items to be in a language other than
         English language, the Distributor shall promptly notify Synon and,
         subject to the provisions of this Agreement, shall undertake to comply
         therewith in a manner satisfactory to Synon.

13.6     CONFORMITY WITH LOCAL LAWS
         The rights and obligations of the parties hereunder are subject to all
         applicable laws, orders, regulations, directions and restrictions of
         the various governmental authorities having jurisdiction over the
         parties.  In the event that any of the foregoing (excluding a law,
         order, regulation, direction or restriction of the European
         Commission) shall result in a modification or alteration of this
         Agreement, either party hereto may request that this Agreement be
         modified with respect thereto, to the reasonable satisfaction of the
         parties hereto, and the parties shall so amend this agreement.  If
         such modification amounts to a material amendment or variation to this
         agreement either party hereto may, in its sole discretion, terminate
         this Agreement on ten (10) days prior written notice.

13.7     PRIOR AUTHORISATION
         If any notification or approval of any governmental or other authority
         in the Territory is required prior to, or following, the execution of
         this Agreement (or any Licence Agreement or Maintenance Agreement) the
         Distributor agrees to notify Synon promptly of such requirements and
         to comply fully therewith.  In the event that (a) any such authority
         shall require the parties to amend this Agreement as a condition
         precedent to such approval or (b) any such approval shall not be
         received within one hundred twenty (120) days following submission of
         a written request for such approval, either party may terminate this
         Agreement without liability except with respect to any prior breach to
         the other party upon thirty (30) days' prior written notice to such
         party.  All monies due to Synon shall be paid in accordance with
         Clause 10.3(a) and all other actions following termination shall
         apply.
                                                                              16
<PAGE>   17
13.8     DEEMED AMENDMENT
         If any term or provision or any part thereof (in this sub-Clause 13.8
         called the offending provision) contained in this Agreement shall be
         declared or become unenforceable, invalid or illegal for any reason
         whatsoever including but without derogating from the generality of the
         foregoing a decision by any competent domestic or European Economic
         Court, the European Commission, domestic or European Community law,
         the other terms and provisions of this Agreement shall remain in full
         force and effect as if this Agreement had been executed without the
         offending provision appearing herein and with any required amendment
         and any offending provision shall thereupon cease to have effect.  At
         the request of Synon the Distributor shall assist Synon and provide
         all necessary information and support to Synon for the purpose of
         making an application to the European Commission for negative
         clearance of this Agreement pursuant to Article 2 of Council
         Regulation No. 17 or for notification of this Agreement with a view to
         obtaining exception under Article 85(3) of the Treaty of Rome.
         Furthermore the distributor agrees to Synon making such amendments to
         this agreement as it considers necessary to obtain such negative
         clearance or exemption or any comfort letter in relation thereto and
         shall thereby be bound by any such amendments.

13.9     PUBLICITY
         The Distributor shall not publicise or disclose to any third party by
         other means any of the terms or provisions of this Agreement, or the
         discussions relating thereto, without the prior written consent of a
         duly authorised officer of Synon, except as required by law.

13.10    SEVERABILITY
         If any provision of this Agreement is determined by a court of
         competent jurisdiction to be in violation of any applicable law or
         otherwise invalid or unenforceable, such provision shall to such
         extent as it shall be determined to be illegal, invalid or
         unenforceable under such law be deemed null and void, but this
         Agreement shall otherwise remain in full force and effect.

13.11    ENTIRE AGREEMENT
         This Agreement sets forth the entire agreement between the parties
         hereto with respect to the subject matter hereof and merges all
         discussions between them and supersedes and replaces any and every
         other agreement which may have existed between Synon and the
         Distributor to the extent that any such agreement relates or related
         to the establishment of any arrangement for the distribution,
         marketing, sale or support of any of the Products.  Each of the
         parties acknowledges that, in entering into this Agreement, it does
         not do so on the basis of and does not rely on, any representation,
         warranty or other provision except as expressly provided herein, and
         all conditions, warranties or other terms implied by statute or common
         law are hereby excluded to the fullest extent permitted by law.

13.12    PROPER LAW AND JURISDICTION
         The validity of this Agreement and the rights, obligations and
         relations of the parties hereunder shall be construed and determined
         under and in accordance with the laws of England and each party hereby
         agrees to submit to the jurisdiction of the English Courts.

13.13    COUNTERPARTS
         The Agreement may be executed in any number of separate counterparts,
         each of which shall be deemed to be an original but which together
         shall constitute one and the same instrument.


IN WITNESS WHEREOF the parties hereto have caused this Agreement to be executed
by their duly authorised representatives the day and year first above written.

PART II - PRICE SCHEDULE
(a)      The current licence fees and maintenance fees on which all commission
         payable to Synon shall be calculated are as enclosed.  All prices are
         expressed in Deutschmarks and these prices may be changed by Synon in
         accordance with Clause 7.1(c).

         Such fees are subject to variation from time to time at the sole
         discretion of Synon and any such increases shall be notified to the
         Distributor by Synon in writing in accordance with sub-Clause 7.1.

(b)      The commission payable to Synon by the Distributor (or vice versa)
         under this Agreement shall be calculated as follows, except in years
         one and two where the Document of Understanding will rule:

         i)      If the Distributor shall enter a Licence Agreement and install
                 the software pursuant thereto - [ ]* of Synon's then current
                 licence fee.
         ii)     The Distributor shall pay to Synon [ ]* of Synon's then current
                 annual maintenance fee for each Maintenance Agreement it shall
                 enter, and [ ]* of Synon's then current maintenance fee on each
                 renewal of such maintenance agreement, provided Synon has not
                 received prior written notice of termination of any such
                 agreement.

(c)      The Distributor is not in any way restricted or limited to licence the
         Products at the fees listed in paragraph (a) above.  Those are the
         fees (as amended from time to time) on which Synon's commission shall
         be calculated in accordance with this Appendix.

(d)      If there is an MAI agreement with IBM in force in the territory or if
         Synon pays a royalty to any third party for distribution rights of any
         product [ ]*.  If the distributor is to make the payment then it
         warrants that it will pay IBM or any third party in accordance with its
         terms and Synon will invoice the distributor at the appropriate share
         of the price schedule, less Synon's share of the MAI or other third
         party royalty.  This shall only apply to products covered by MAI or
         third party royalty agreements.  [ ]*

         If Synon is to make the payment then Synon will invoice the
         distributor at the appropriate share of the price schedule plus the
         distributors share of a MAI or other third party royalty agreement.
         This shall apply to products covered by the MAI or other third party
         royalty agreements.  [ ]*

4.0      MARKET SEGMENTS

         AS/400 and RS/6000
         CGI INFORMATIK will market, sell and support Synon products in the
         AS/400 and RS/6000 markets in Germany.  Neither Synon Europe nor Synon
         Deutschland have plans to appoint another distributor in this market
         sector but reserves the right to deal direct with any organisation in
         the sector, especially software and services companies, which decide
         not to licence Synon software from CGI.  In these cases all sales and
         support will be from Synon Europe.  We expect these situations to be
         few in number and will work with CGI to avoid the need for any such
         action.

         HP/UX and NT
         CGI will be entitled to market, sell and support all the Synon
         products made available to the German market.  However, Synon
         Deutschland GmbH will have the right to appoint other distributors or
         agents for the HP/UX and Microsoft NT environments.

         For the duration of this agreement CGI shall not offer Complementary
         Marketing Agreements to any of the following companies for the AS/400
         market; Progress, Lansa, JBA, Powersoft, Gupta.

         If such an agreement is made by CGI with the above companies, Synon
         reserves the right to appoint other distributors for the German AS/400
         and RS 6000 markets.

5.0      CONTRACT TERM

         The term of the contract will be a minimum of three years from the
         date of signature, after which it will be renewable as stated in
         clause 10.1 of the International Distribution Agreement.

6.0      TRANSFER STRATEGY

         All Synon Deutschland employees and those of Synon Europe working in
         Germany will get an offer from CGI for suitable employment under CGI
         INFORMATIK terms and conditions from the date of this contract.  CGI
         will make the payments for all the costs caused by their transfer to
         CGI and for the costs of terminating those who are unwilling to be
         transferred.  This costs are calculated in the one-time costs of 375 K
         Pound  and all payments will be seen as payments to SYNON and quoted
         at 100%.

         The same procedure is planned for all fixed assets and leasing or
         renting agreements which are also calculated in the one-time cost (see
         attached list).

7.0      SOFTWARE AND SERVICE COMPANY CONFLICT

         We do not expect there to be any problems with the above companies,
         but if a conflict should arise and if the company concerned asks to
         deal direct with Synon Europe Ltd, then it shall be able to do so.

              password-controlled access. Each user will have a unique user ID
              and associated password. Datasets will be protected and passwords
              will be controlled by IBM Resource Access Control Facility (RACF)
              or a security program providing equivalent protection. Otherwise,
              each dataset containing Information will be password protected
              and, if practical, each password will be unique. Local Area
              Network environments will have controls similar to the
              requirements set forth above. Access to Information on standalone
              workstations will be controlled. When such systems are not in use,
              Information will be secured.

       b.     each password will be randomly selected, non- obvious and
              non-trivial. Log on passwords will be changed at least every 60
              days. Dataset passwords will be changed at least every six months;

       c.     dial-up facilities will be protected by a secure call-back system
              or other secure method;

       d.     if required by the Discloser, Information will be encrypted when
              it is electronically transmitted outside the Recipient's
              facilities or when public communications facilities are used;

       e.     sharing of passwords and disclosure of passwords and encryption
              keys will be limited to authorized persons;


       f.     displaying and printing of passwords will be either inhibited or
              masked; and

       g.     before any physical storage media containing Information is
              released for reuse, it will be degaussed or completely
              overwritten.

(ELECTRONICALLY, PRELOADED, ON MEDIA OR OTHERWISE), BY USING THE PROGRAM OR
MATERIAL YOU AGREE TO THESE TERMS.

The Program or Material is owned by the International Business Machines
Corporation or its subsidiaries (IBM) or IBM's Suppliers, and is copyrighted
and licensed, not sold.  The "Program" means the original program and all whole
or partial copies of it, including portions merged into other Programs.  A
Program consists of machine-readable instructions and audio/visual content
(such as images, text, recordings, or pictures).  A "Material" consists of
Program documentation and programming tools.

The term "Early Release" means that the Program or Material is not formally
released or generally available.  The term does not imply that formal release
or general availability will take place.  IBM does not guarantee that a Program
or Material made generally available will be similar to, or compatible with,
Early Release versions.

IBM grants you a nonexclusive, nontransferable license under the terms stated
below to the Program or Material in the country in which you acquire it.

This Agreement is the complete and exclusive agreement regarding a Program or
Material and replaces any prior oral or written communications between you and

Material.  The terms of this license apply to each copy you make.  You must
reproduce the copyright notice and any other legend of ownership on each copy,
or partial copy, of the Program or Material.

June 30, 1997.  Unless we specify that you may retain the Program or Material
in the documentation accompanying the Program or Material (in which case, an
additional charge will apply), you agree to destroy the Program or Material and
all copies of it within 30 days of when this license ends.

2.   NO WARRANTY:

SUBJECT TO ANY STATUTORY WARRANTIES WHICH CANNOT BE EXCLUDED, IBM MAKES NO
WARRANTIES OR CONDITIONS EITHER EXPRESS OR IMPLIED, INCLUDING WITHOUT
LIMITATION, WARRANTIES OF NON-INFRINGEMENT AND THE IMPLIED WARRANTIES OF

PERFORMANCE OR DOCUMENTATION FOR THE PROGRAM OR MATERIAL.

This exclusion also applies to any of IBM's subcontractors, suppliers or
program developers (collectively called "Suppliers').

3.   LIMITATION OF LIABILITY:

NEITHER IBM NOR ITS SUPPLIERS WILL BE LIABLE FOR ANY DIRECT OR INDIRECT DAMAGES,
INCLUDING WITHOUT LIMITATION, LOST PROFITS, LOST SAVINGS, OR ANY INCIDENTAL,

                  SOFTWARE LICENSE AGREEMENT--PERPETUAL SYNON

                                     SYNON
- --------------------------------------------------------------------------------
Software License Agreement between Synon, Inc. ("Synon") and the undersigned
Licensee ("Licensee"). This agreement sets forth the terms and conditions under
which Synon licenses Licensee to use the Programs in object code listed in
Schedule A ("Program(s)") and supporting documentation delivered with the
Program(s).

LICENSE: In consideration of payment of the License Fee specified in Schedule A
and subject to the terms hereof, Synon grants to Licensee a perpetual, personal,
non-transferable, non-exclusive license to use the Program(s) on the computer at
the location specified below. Unless otherwise agreed to in writing by Synon,
Licensee agrees (i) not to use the Program(s) to develop application software
for entities other than Licensee, (ii) not to permit any other entity to use the
Program(s) on a timesharing or other basis and, (iii) not to permit any other
entity to use the application software developed by the Program(s).

Licensee agrees that, upon execution of this Agreement, the License Fee is
Payable as provided in Schedule A. Failure to make payment of the License Fee
when due will be a breach of this Agreement, and in the event of such a breach,
Synon may render the Program(s) inoperative by withholding authorization codes
and may terminate this Agreement by written notice to Licensee. Licensee
acknowledges that the Program(s) will be or become inoperative if Synon
withholds authorization codes.

SYNON'S RIGHTS. Synon represents and warrants that it has the right to grant
this license. Synon is acting as principal and not as agent for any affiliate or
related entity of Synon in granting this license. Licensee acknowledges that it
has and is acquiring no rights against any affiliate or related entity of Synon
or any third party who may own the Program(s).

LIMITATION OF LIABILITY. Licensee agrees that, except for Synon's obligations to
indemnify Licensee under infringement actions, as provided herein, Synon's
liability for damages under or in connection with this Agreement, regardless of
the form of action, is limited to the License Fee received under this Agreement.
In no event will Synon be liable for consequential, indirect or incidental
damages, even if Synon foresees or has been advised of the possibility of those
damages. Licensee acknowledges that the amount of the License Fee payable under
this Agreement is related to the foregoing limitations on Synon's liability and
that the License Fee would be greater if Synon's liability were not so limited.

THIS AGREEMENT INCLUDES THE TERMS SET FORTH ON THE REVERSE SIDE OF THIS SHEET.
BY EXECUTION OF THIS AGREEMENT, LICENSEE ACKNOWLEDGES THAT IT HAS READ AND
ACCEPTED THOSE TERMS.

UPGRADES. This License is for use of the Program(s) on the CPU model specified
in Schedule A. If Licensee desires to use the Program(s) on a different CPU
model, Synon may charge an Upgrade Fee and an increased Maintenance Fee in
accordance with Synon's policy then in effect. Failure to make payment of the
Upgrade Fee when due will be a breach of this Agreement, and in the event of
such a breach, Synon may render the Program(s) inoperative on the new CPU model
by withholding authorization codes. Synon will issue a new authorization code
for the upgraded CPU model upon payment of the Upgrade Fee.

SUPPORT AND MAINTENANCE. Synon will provide Licensee with the following support
and maintenance for the Program(s) (i) for the first 90 days from the date of
this Agreement without additional charge, (ii) for the next 12 months upon
payment by Licensee of the Maintenance Fee by the date specified in Schedule A
and (iii) on an annual basis thereafter subject to payment of the applicable
Maintenance Fee within 30 days of invoice.

          1.     Telephone support through Synon's offices;
          2.     The right to receive support services at Licensee's site, at 
                 Synon's standard billing rate, subject to availability and
                 scheduling of Synon personnel;
          3.     Updated versions of the Program(s) as they may be released; and
          4.     Error corrections as made.

WARRANTY. Synon warrants that the Program(s) will perform in substantial
compliance with the reference manual supplied by Synon with the Program(s). This
warranty shall extend for a period of 90 days from the date of this Agreement.
Synon's sole obligations in the event of a breach of this warranty will be to
correct any material defects or errors of which it is given written notice
within the 90 day period or, if it fails to correct those errors within 30 days
of receipt of written notice, to refund to Licensee the License Fee, if any,
against return of the Program(s) and all supporting documentation. Synon also
warrants that the Program(s) does not, as of the date of this Agreement,
infringe any copyright, trade secret or issued United States patent of any third
party. Synon's sole obligations in the event of breach of this warranty of
non-infringement are those specified in this paragraph. Synon agrees to
indemnify Licensee against legal fees and liability to third parties arising
from any claim of such infringement. Synon shall have the right to control the
defense or settlement of any such claim. If use of the Program(s) by Licensee is
enjoined by any such infringement proceeding, Synon shall if possible without
unreasonable expense obtain the right for Licensee to use the Program(s), or
shall refund to Licensee the License Fee, if any, paid under this Agreement for
the Program(s). Except for the express warranties made in this paragraph, SYNON
MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT TO THE PROGRAM(s),
INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR
PURPOSE.

TAXES. Licensee agrees to pay, or reimburse Synon for, any taxes resulting from
this Agreement, exclusive of taxes based on Synon's net income.

PROPRIETARY DATA. Licensee acknowledges that the Program(s) and the supporting
documentation constitute and will remain property and trade secrets of Synon,
its affiliates and/or third parties and their respective successors and assigns,
and Licensee does not have and shall not acquire any proprietary rights thereto.
Licensee agrees that it will not, and will not permit others to, copy or
decompile, or use in any way not expressly authorized by this Agreement, the
Program(s) or the supporting documentation. Licensee may, however, make one copy
of the Program(s) for backup purposes.

TERMINATION. Synon may terminate Licensee's right to use the Program(s) by
notice in writing to Licensee if Licensee breaches any material term of this
Agreement and such breach is not cured within 10 days after notice from Synon to
Licensee. Upon any termination of Licensee's rights to use the Program(s),
Licensee shall discontinue use of the Program(s), return all copies of the
Program(s) and supporting documentation and delete all copies of the Program(s)
from Licensee's CPUs and certify to Synon that it has done so.

MISCELLANEOUS. This Agreement is the complete statement of the terms and
conditions of Synon's license of the Program(s) and Synon's obligations to
Licensee. There are no representations, warranties, undertakings or agreements
between Synon and Licensee except as set forth in this Agreement. This Agreement
shall be governed by and construed in accordance with the laws of the State of
California. This Agreement is effective upon execution by Synon at its principal
office located in Larkspur, California, USA.

<PAGE>   2



                              OFFICE BUILDING LEASE


1.      PARTIES. This Lease, dated, for reference purposes only SEPTEMBER 11,
1989, is made by and between Lincoln Property Company N.C., Inc. as manager and
agent for the owner (herein called "Landlord") and SYNON, INC., an Illinois
corporation (herein called "Tenant").


2.      PREMISES. Landlord does hereby lease to Tenant and Tenant hereby leases
from Landlord that certain office space (hereinafter called "Premises")
consisting of 16,112 usable square feet outlined in red on Exhibit A attached
hereto and 18,048 rentable square feet, including corridors being situated on
the 2ND/3RD floor(s) of that certain building known as 1100 LARKSPUR LANDING
CIRCLE, SUITE 300, LARKSPUR, CALIFORNIA (hereinafter called "Building") which is
one of several buildings in Larkspur Landing Office Park (hereinafter called
"Office Park") *(SEE PAGE 13)

        Said Lease is subject to the terms, covenants, and conditions herein set
forth and the Tenant covenants as a material part of the consideration for this
Lease to keep and perform each and all of said terms, covenants, and conditions
by it to be kept and performed and that this Lease is made upon the condition of
said performance.

        For the purposes of maintaining an economical and proper distribution of
tenants throughout the Office Park which is acceptable to Landlord, Landlord
shall have the right from time to time during the term of this Lease to relocate
the Premises in the Office Park; provided, however, (i) that the rentable and
usable areas of the new location in the Office Park are of equal size to the
Premises (subject to a variance of up to 10%) and the amount of Basic Rent
(hereinafter defined) payable under this Lease is not increased, (ii) that if
the then prevailing rental for the new location is less than the amount of Basic
Rent being paid for the Premises, the Basic Rent shall be reduced to equal the
then prevailing base rental for the new location, (iii) that Landlord shall pay
the cost of providing improvements to Tenant in the new location comparable to
the improvements Tenant now has in the Premises, and (iv) that Landlord shall
pay the expenses reasonably incurred by Tenant in connection with the relocation
of the Premises, including without limitation the costs of moving, door
lettering, telephone relocation, and reasonable quantities of new stationery.
Landlord shall deliver to Tenant written notice of Landlord's election to
relocate the Premises, specifying the new location and the amount of Basic Rent
payable therefor at least thirty (30) days prior to the date that the relocation
is to be effective. If the relocation of the Premises is not acceptable to
Tenant, Tenant, for a period of ten (10) days after receipt of Landlord's notice
to relocate, shall have the right by delivering written notice to Landlord to
terminate this Lease effective thirty (30) days after the delivery of such
written notice to Landlord.

3.      TERM. The term of this Lease shall be for SEVEN years, commencing on the
1ST day of OCTOBER, 1989, and ending on the 30TH day of SEPTEMBER, 1996.

4.      POSSESSION. If the Landlord, for any reason whatsoever, cannot deliver
possession of the said Premises to the Tenant at the commencement of the term
hereof, this Lease shall not be void or voidable nor shall Landlord be liable to
Tenant for any loss or damage resulting therefrom, nor shall the expiration date
of the above term be in any way extended, but in that event, all rental amounts
shall be abated during the period between the commencement of said term and the
time when Landlord delivers possession.

        In the event that Landlord shall permit Tenant to occupy the Premises
prior to the commencement date of the term, such occupancy shall be subject to
all provisions of this Lease. Said early possession shall not advance the
termination date hereinabove provided.

5.      BASIC RENT. Tenant agrees to pay to Landlord as rental without prior
notice or demand, for the Premises the sum of: THIRTY-SIX THOUSAND SIX HUNDRED


<PAGE>   3




THIRTY-EIGHT AND NO/100 - - - - - - ($36,638.00) Dollars (hereinafter called
"Basic Rent", on or before the first day of the first full calendar month of the
terms hereof and a like sum, as adjusted in the manner specified in Article 6
(hereinafter called "Adjusted Basic Rent"), on or before the first day of each
and every successive calendar month thereafter during the terms hereof, except
that the first month's rent shall be paid upon the execution hereof. The Basic
Rent shall be paid until adjusted in the manner specified in Article 6.
Thereafter, the prevailing Adjusted Basic Rent shall be the amount paid. Rental
for any period during the term hereof which is for less than one (1) month shall
be a prorated portion of the monthly installment due under the terms herein,
based upon a thirty (30) day month. Said amount shall be paid to Landlord,
without deduction or offset, in lawful money of the United States of America,
which shall be legal tender at the time of payment at the Office of the
Building, or to such other person or at such other place as Landlord may from
time to time designate in writing.

6.      ADJUSTED BASIC RENT. Each year during the term of this Lease other than
the Base Year, the Basic Rent or the prevailing Adjusted Basic Rent, as the case
may be, shall be adjusted for the ensuing twelve (12) months by the use of the
Consumer Price Index (All Urban Consumers component) for the San
Francisco-Oakland Area (1967 = 100) published by the Bureau of Labor Statistics
of the U. S. Department of Labor. The Basic Rent will be increased by the
percentage increase, if any, between the latest index published just prior to
the commencement of the Lease Term and the comparable latest index published
just prior to January of the following year to arrive at the Adjusted Basic
Rent. Each year thereafter, the Adjusted Basic Rent will be increased by the
percentage increase, if any, between the index published just prior to January
of the subsequent year and the comparable latest index published just prior to
January of the preceding year.

        In case the U. S. Department of Labor shall discontinue the computation
and publication of said Consumer Price Index or the publication thereof should
be delayed so as to prevent its use hereunder at the times required, there shall
be substituted therefor by Landlord such other index or method of ascertaining
changes in the price level as, in the opinion of Landlord, most closely
resembles the Consumer Price Index and method of arriving at the index figure by
said Bureau.

7.      ADDITIONAL RENT. Tenant agrees to pay to Landlord as additional rental
(hereinafter "Additional Rent") a sum equal to Tenant's Proportional Share
(hereinafter defined) of any increase in the Direct Costs (hereinafter defined).

        For the purposes of this Article, Tenant's Proportional Share shall be a
sum equal to 23.10%.


        For the purposes of this Article, the term "Direct Costs" shall include:
(i) property taxes paid or incurred by Landlord consisting of all real or
personal property taxes (and any tax levied wholly or partly lieu thereof)
imposed against the Building and all related improvements, including the
adjacent walks, parking lots, and the land upon which they are situated, but
shall not include any net income or franchise taxes; (ii) operating costs paid
or incurred by Landlord in maintaining, managing, and operating Building, its
equipment, and the adjacent walks, parking lots, landscaped areas, and the land
upon which they are located, including without limiting the generality of the
foregoing, the costs of services of both independent contractors and employees
(inclusive of employment taxes and fringe benefits) who perform duties connected
with the day to day management, operation, maintenance, and repair of the
Building, and the costs incurred by reason of any changes in any regulations,
rules, requirements, laws, codes, directives, or similar pronouncements of any
Federal, state, county, city, or other governmental or regulatory agency which
require changes in or to the physical construction of or related equipment of or
used in the Building or the adjacent walks, parking lots, landscaped areas,
and/or items used in the operation and maintenance thereof.

        For the purposes of this Lease the term "Base Year" shall refer to and
mean the calendar year in which this Lease term commences.

to and mean each successive calendar year of the term of this Lease after the
Base Year.

        For the purposes of this Article, the Term "Current Year" shall refer to
and mean each successive calendar year as it becomes the current calendar year,
beginning with the first calendar year next following the Base Year.

        Each year during the term of this Lease other than the Base Year,
Landlord shall furnish to Tenant a written statement showing in reasonable
detail Landlord's Direct Costs for the applicable Comparison Year and for the
Base Year, and showing the amount, if any, of Additional Rent due from Tenant.

        To compute the Additional Rent, if the Direct Costs paid or incurred by
the Landlord for the Comparison Year are in excess of the Direct Costs paid or
incurred by Landlord for the Base Year, then the Tenant shall pay, as Additional
Rent, Tenant's Proportional Share thereof. Upon Tenant's receipt of Landlord's
statement for the first Comparison Year, Tenant shall pay in full the total
amount of Additional Rent for the first Comparison Year, and, in addition, for
the Current Year the amount of such Additional Rent shall be used as an estimate
for the Current Year. The amount of the Additional Rent shall be divided in
twelve (12) equal monthly installments and Tenant shall pay to Landlord,
concurrently with the Basic Rent or the prevailing Adjusted Basic Rent, as the
case may be, which is next due following the receipt of said statement from
Landlord, an amount equal to one (1) such monthly installment multiplied by the
number of months from January in the Current Year in which Landlord's said
statement is submitted to the month of such statement, both months inclusive.
Subsequent installments of Additional Rent shall be payable concurrently with
the Basic Rent or the prevailing Adjusted Basic Rent, as the case may be, for
the balance for that Current Year and shall continue until the statement for the
next Comparison Year is rendered. If the next or any succeeding Comparison Year
results in an increase in Direct Costs over the immediately preceding Comparison
Year, then, upon receipt of said statement from Landlord, Tenant shall pay a
lump sum equal to Tenant's Proportional Share of the Direct Costs less the total
of the monthly installments paid during the immediately preceding Comparison
Year, and the estimated monthly installments of Additional Rent to then be paid
for the Current Year shall be adjusted to reflect such increased Direct Costs.
If the next or any succeeding Comparison Year results in a decrease in Direct
Costs over the immediately preceding Comparison Year, then, upon receipt of said
statement from Landlord, the estimated monthly installments of Additional Rent
to then be paid for Current Year shall be adjusted to reflect such decreased
Direct Costs, and the difference between Tenant's Proportional Share of the
decreased Direct Costs and the total of the monthly installments paid during the
immediately preceding Comparison Year shall be credited to the first (and
succeeding, if applicable) installments of Additional Rent to be paid for the
Current Year.

        The Direct Costs for any Calendar Year that the Building is not at least
ninety-five percent (95%) occupied shall be adjusted to reflect a ninety-five
percent (95%) level of occupancy.

        If the term of this Lease has expired and/or Tenant has vacated the
Premises, when the final determination is made of Tenant's share of Direct Costs
for the year in which this Lease terminated, Tenant shall immediately pay any
increase due over the estimated amounts paid and, conversely, any overpayment
made in the event said costs decrease shall be immediately rebated by Landlord
to Tenant.

8.      SECURITY DEPOSIT. Tenant has deposited with Landlord the sum of
TWENTY-SIX THOUSAND NINE HUNDRED FIFTY AND NO/100* - - - - - - - - -($26,950.00)
Dollars. Said sum snail be held by Landlord as security for the faithful
performance by Tenant of all the terms, covenants, and conditions of this Lease
to be kept and performed by Tenant during the term hereof. If Tenant defaults
with respect to any provisions of this Lease, including, but not limited to the
provisions relating to the payment of rentals, Landlord may (but shall not be
required to) use, apply or retain all or any part of this security deposit for
the payment of any rental or any other sum in default, or for the payment of any
amount which Landlord may spend or become obligated to spend by reason of
Tenant's default, or to compensate Landlord for any other *Plus $9,688.00 which
has been deposited with Landlord as a Security Deposit pursuant to that certain
Lease dated March 9, 1988, for a total Security Deposit of $36,638.00.


                                      -3-
<PAGE>   5

loss or damage which Landlord may suffer by reason of Tenant's default. If any
portion of said deposit is so used or applied, Tenant shall within five (5) days
after written demand therefor, deposit cash with Landlord in an amount
sufficient to restore the security deposit to its original amount and Tenant's
failure to do so shall be a material breach of this Lease. Landlord shall not be
required to keep this security deposit separate from its general funds, and
Tenant shall not be entitled to interest on such deposit. If Tenant shall fully
and faithfully perform every provision of this Lease to be performed by it, the
security deposit or any balance thereof shall be returned to Tenant (or, at
Landlord's option, to the last successor to Tenant' s interest hereunder) at the
expiration of the Lease term. In the event of termination of Landlord's interest
in this Lease, Landlord shall transfer said deposit to Landlord's successor in
interest.

9.      USE. Tenant shall use the Premises for general office purposes and shall
not use or permit the Premises to be used for any other purpose without the
prior written consent of Landlord.

        Tenant shall not do or permit anything to be done in or about the
Premises nor bring or keep anything therein which will in any way increase the
existing rate of or affect any fire or other insurance upon the Building or any
of its contents, or cause cancellation of any insurance policy covering the
Building or any part thereof or any of its contents. Tenant shall not do or
permit anything to be done in or about the Premises which will in any way
obstruct or interfere with the rights of other tenants or occupants of the
Building or injure or annoy them or use or allow the Premises to be used for any
improper, immoral, unlawful or objectionable purpose, nor shall Tenant cause,
maintain, or permit any nuisance in, on, or about the Premises. Tenant shall not
commit or suffer to be committed any waste in or upon the Premises.

10.     COMPLIANCE WITH LAW. Tenant shall not use the Premises or permit
anything to be done in or about the Premises which will in any way conflict with
any law, statute, ordinance, or governmental rule or regulation now in force or
which may hereafter be enacted or promulgated. Tenant shall, at its sole cost
and expense, promptly comply with all laws, statutes, ordinances, and
governmental rules, regulations, or requirements now in force or which may
hereafter be in force, and with the requirements of any board of fire insurance
underwriters or other similar bodies now or hereafter constituted, relating to,
or affecting the condition, use, or occupancy of the Premises, excluding
structural changes not related to or affected by Tenant's improvements or acts.
The judgment of any court of competent jurisdiction or the admission of Tenant
in any action against Tenant, whether Landlord is a party thereto or not, that
Tenant has violated any law, statute, ordinance, or governmental rule,
regulation, or requirement, shall be conclusive of that fact as between the
Landlord and Tenant.

11.     CONSTRUCTION. Prior to the commencement of the term hereof, Landlord
shall furnish and install within the Premises the tenant improvements shown on
preliminary plans dated 8/1/89, attached hereto and marked Exhibit B. The costs
to be paid by Tenant for such work are $ * . Tenant agrees that it will pay such
costs at the time the Premises are ready for Tenant's occupancy. *Landlord will
contribute up to the sum of $268,302.00 towards Tenant Improvement cost.

        All work not within the normal scope of the construction trades employed
in building construction, such as the furnishing and installing of telephone
equipment and wiring, furniture, furnishings, office equipment, trade fixtures,
carpeting (unless installed by Landlord under the first part of this Article),
special draperies (in addition to Building standard casement draperies for which
no substitution is permitted), and other items of personal property, shall be
furnished and installed by the Tenant at Tenant's expense. Tenant shall adopt a
schedule in conformance with the schedule of Landlord's contractors and conduct
its work in such a manner as to maintain harmonious labor relations and so as
not to unreasonably interfere with or delay the work of the Landlord's
contractors. Tenant's contractors, subcontractors, and labor shall be acceptable
to and approved by Landlord, and shall be subject to the administrative
supervision of the Landlord's general contractor. Contractors or subcontractors
engaged by Tenant shall insure, as far as may be 

                                      -4-
<PAGE>   6

reasonably possible, the progress of the work without interruption on account of
strikes, work stoppage or other causes for delay.

        Landlord shall give reasonable access and entry to the Premises to
Tenant and its contractors and subcontractors to enable Tenant to adapt the
Premises for Tenant's use.

12.     ALTERATIONS AND ADDITIONS. Tenant shall not make or suffer to be made
any alterations, additions, or improvements to or of the Premises or any part
thereof without the written consent of Landlord first had and obtained and any
alterations, additions, or improvements to or of said Premises, including, but
not limited to, wall covering, paneling, and built-in cabinet work, but
excepting movable furniture and trade fixtures, shall on the expiration of the
term become a part of the realty and belong to the Landlord and shall be
surrendered with the Premises. In the event Landlord consents to the making of
any alterations, additions, or improvements to the Premises by Tenant, the same
shall be made by Tenant at Tenant's sole cost and expenses and any contractor or
person selected by Tenant to make the same must first be approved of in writing
by the Landlord. Upon the expiration or sooner termination of the term hereof,
Tenant shall, upon written demand by Landlord given at least thirty (30) days
prior to the end of the term, at Tenant' s sole cost and expense forthwith and
with all due diligence remove any alterations, additions, or improvements made
by Tenant which are designated by Landlord to be removed, and Tenant shall,
forthwith and with all due diligence at its sole cost and expense, repair any
damage to the Premises caused by such removal.

13.     REPAIRS. By taking possession of the Premises, Tenant shall be deemed to
have accepted the Premises as being in good and sanitary order, condition, and
repair. Tenant shall, at Tenant's sole cost and expense, keep the Premises and
every part thereof in good condition and repair, damage thereto from causes
beyond the reasonable control of Tenant and from ordinary wear and tear
excepted. Tenant shall upon the expiration or sooner termination of this Lease
hereof surrender the Premises to the Landlord in good condition, ordinary wear
and tear and damage from causes beyond the reasonable control of Tenant
excepted. Except as specifically provided in an addendum, if any, to this Lease,
Landlord shall have no obligation whatsoever to alter, remodel, improve, repair,
decorate, or paint the Premises or any part thereof and the parties hereto
affirm that Landlord has made no representations to Tenant respecting the
condition of the Premises or the Building except as specifically herein set
forth.

        Notwithstanding the provisions of Article 13(a), Landlord shall repair
and maintain the structural portions of the Building, including the basic
plumbing, air conditioning, heating, and electrical systems, installed or
furnished by Landlord, unless the need for such maintenance and repairs are
caused, in part or in whole, by the act, neglect, fault, or omission of any duty
by the Tenant, its agents, servants, employees, or invitees, in which case
Tenant shall pay to Landlord the reasonable cost of such maintenance and
repairs. Landlord shall not be liable for any failure to make any such repairs
or to perform any maintenance unless such failure shall persist for an
unreasonable time after written notice of the need of such repairs or
maintenance is given to Landlord by Tenant. Except as provided in Article 24,
there shall be no abatement of rent and no liability of Landlord by reason of
any injury to or interference with Tenant's business arising from the making of
any repairs, alterations, or improvements in or to any portion of the Building
or the Premises or in or to fixtures, appurtenances, and equipment therein.
Tenant waives the right to make repairs at Landlord's expense under any law,
statute, or ordinance now or hereafter in effect.

14.     LIENS. Tenant shall keep the Premises and the Building free from any
liens arising out of any work performed, materials furnished, or obligations
incurred by Tenant. Landlord may require, at Landlord's sole option, that Tenant
shall provide to Landlord, at Tenant's sole cost and expense, a lien and
completion bond in an amount equal to one and one-half (1 1/2) times any and all
estimated costs of any improvements, additions, or alterations in the Premises
to insure Landlord against any liability for mechanics' and materialmen's liens
and to insure completion of the work.

15.     ASSIGNMENT AND SUBLETTING. Neither Tenant nor its heirs or assigns shall
either voluntarily or by operation of law, assign, transfer, mortgage, pledge,
hypothecate, or encumber this Least or any interest therein, and shall not
sublet the Premises, or any part thereof, or any right or privilege appurtenant
thereto , or suffer any other person (the employees, agents, servants, and
invitees of Tenant excepted) to occupy or use the said Premises, or any part
thereof, without the prior written consent of Landlord first had and obtained
and any attempt to do so without such consent shall be wholly void and shall
constitute a breach of this Lease.

        In the event that Tenant desires to sublet the Premises or any part
thereof, Tenant shall notify Landlord in writing not less than ninety (90) days
in advance of the proposed subletting, designating in such writing the name and
legal composition of the proposed subtenant, the nature of the proposed
subtenant's business to be carried on in the Premises, the terms and provisions
of the proposed sublease, and shall therein or subsequently furnish such
reasonable financial information regarding the proposed subtenant as Landlord
may request. Landlord shall be allowed thirty (30) days after its receipt of
such notice from Tenant in which to give its written notice to Tenant that
Landlord will terminate this Lease as to the Premises, or the part thereof
proposed to be sublet, effective upon the date of such proposed subletting. If
Landlord fails to give such notice to Tenant, then Tenant may sublet the
Premises, or the part thereof designated in said notice to Landlord, only with
the written consent of Landlord first had and obtained, which consent shall not
be unreasonably withheld. For the purposes of this provision, Landlord may, at
its sole option, reasonably withhold its consent to the subletting if the
proposed subtenant is unwilling to execute a document in a form satisfactory to
Landlord in which it agrees to substantially all of the terms and conditions of
this Lease, and/or if the financial condition of the proposed subtenant is not
substantially similar to that of the Tenant as of the date of this Lease.

        A consent by Landlord to one assignment, subletting, occupation, or use
by any other person shall not be deemed a consent to any subsequent assignment,
subletting, occupation, or use by another person.

16.     HOLD HARMLESS. Tenant shall indemnify and hold harmless Landlord against
and from any and all claims arising from Tenant's use of the Premises for the
conduct of its business or from any activity, work, or other thing done,
permitted, or suffered by the Tenant in or about the Building, and shall further
indemnify and hold harmless Landlord against and from any and all claims arising
from any breach or default in the performance of any obligation on Tenant's part
to be performed under the terms of this Lease, or arising from any act or
negligence of the Tenant, or any officer, agent, employee, guest, or invitee of
Tenant, and from all and against all costs, attorneys' fees, expenses, and
liabilities incurred in or about any such claim or any action or proceeding
brought thereon, and, in any case, action, or proceeding to be brought against
landlord by reason of any such claim, Tenant, upon notice from Landlord, shall
defend the same at Tenant's expense by counsel reasonably satisfactory to
Landlord. Tenant, as a material part of the consideration to Landlord, hereby
assumes all risk of damage to property or injury to persons in, upon, or about
the Premises, from any cause other than landlord's negligence, and Tenant hereby
waives all claims in respect thereof against Landlord.

        Landlord or its agents shall not be liable for any damage to property
entrusted by Tenant to employees of the Building, nor for loss or damage to any
property by theft or otherwise, nor for any injury to or damage to persons or
property resulting from fire, explosion, falling plaster, steam, gas,
electricity, water, or rain which may leak from any part of the Building or from
the pipes, appliances, or plumbing works therein or from the roof, street, or
subsurface, or from any other place resulting from dampness or any other cause
whatsoever, unless caused by or due to the negligence of Landlord, its agents,
servants, or employees. Landlord or its agents shall not be liable for
interference with the light or other incorporeal hereditaments, loss of business
by Tenant, or any latent defect in the Premises or in the Building. Tenant shall
give prompt notice to Landlord in case of fire or accidents in the Premises or
in the Building or of defects therein or in the fixtures or equipment.




                                      -6-

17.     SUBROGATION. As long as their respective insurers so permit, Landlord
and Tenant hereby mutually waive their respective rights of recovery against
each other or any loss insured by fire, extended coverage, and other property
insurance policies existing for the benefit of the respective parties. Each
party shall obtain any special endorsements, if required by their insurer to
evidence compliance with the aforementioned waiver.

18.     LIABILITY INSURANCE. Tenant shall, at Tenant's sole cost and expense,
obtain and keep in force during the term of this Lease a policy of comprehensive
public liability insurance insuring Landlord and Tenant against any liability
arising out of the ownership, use, occupancy, or maintenance of the Premises and
all areas appurtenant thereto. Such insurance at all times shall be a combined
single aggregate policy in an amount of not less than one million dollars
($1,000,000.00). These limits of said insurance shall not, however, limit the
liability of the Tenant hereunder. Tenant may carry said insurance under a
blanket policy, provided, however, said insurance by Tenant shall have a
protective liability endorsement attached thereto in favor of Landlord. If
Tenant shall fail to procure and maintain said insurance, Landlord may, but
shall not be required to, procure and maintain same, but at the expense of
Tenant. Insurance required hereunder, shall be in companies rated A+, AAA, or
better in "Best's Insurance Guide." Tenant shall deliver to Landlord prior to
occupancy of the Premises copies of policies of liability insurance required
herein or certificates evidencing the existence and amounts of such insurance
with a loss payable clause satisfactory to Landlord. No policy shall be
cancellable or subject to reduction of coverage except after ten (10) days,
prior written notice to Landlord.

19.     SERVICES AND UTILITES. Provided that Tenant is not in default hereunder,
Landlord agrees to furnish to the Premises during reasonable hours of generally
recognized business days, to be determined by Landlord at its sole discretion,
and subject to the rules and regulations of the Building, electricity for normal
lighting and fractional horsepower office machines, heat, and air conditioning
required in Landlord's judgment for the comfortable use and occupation of the
Premises, and janitorial service. Landlord shall also maintain and keep lighted
the common stairs, common entries, and toilet rooms in the Building. Landlord
shall not be liable for, and Tenant shall not be entitled to, any reduction of
rental by reason of Landlord's failure to furnish any of the foregoing when such
failure is caused by accident, breakage, repairs, strikes, lockouts, or other
labor disturbances or labor disputes of any character, or by any other cause,
similar or dissimilar, beyond the reasonable control of Landlord. Landlord shall
not be liable under any circumstances for a loss of or injury to property,
however occurring, through or in connection with or incidental to the failure to
furnish any of the foregoing. Wherever heat generating machines or equipment are
used in the Premises which affect the temperature otherwise maintained by the
air conditioning system, Landlord reserves the right to install supplementary
air conditioning units in the Premises and the costs thereof, including the
costs of installation, operation, and maintenance thereof shall be paid by
Tenant to Landlord upon demand by Landlord.

        Tenant will not, without the prior written consent of Landlord first had
and obtained, use any apparatus or device in the Premises, including, but
without limitation thereto, electronic data processing machines, punch card
machines, and machines using in excess of 120 volts, which will in any way
increase the amount of electricity usually furnished or supplied for the use of
the Premises as general office space; nor connect with electric current, except
through existing electrical outlets in the Premises, any apparatus or device for
the purpose of using electric current. If Tenant shall require water or electric
current in excess of that usually furnished or supplied for the use of the
Premises as general office space, Tenant shall first procure the written consent
of Landlord, which Landlord may refuse, to the use thereof and Landlord may
cause a water meter or electrical current meter to be installed in the Premises
so as to measure the amount of the water and electric current consumed for any
such use. The cost of any such meters and of installation, maintenance, and
repair thereof shall be paid for by the Tenant and Tenant agrees to pay to
Landlord promptly upon demand thereof by Landlord for all such water and
electric current consumed as shown by said meters, at the rates charged for such
services by the local public utility furnishing the same, plus any additional
expense incurred in keeping account of the water and






                                      -7-
<PAGE>   9

electric current so consumed. If a separate meter is not installed, such excess
cost for such water and electric current will be established by an estimate made
by a utility company or electrical engineer. Tenant shall install a separate
submeter to measure electric current in excess of that usually furnished for the
use of the Premise as general office space. Tenant shall maintain the separate
air conditioning units installed in Tenant's computer room.

20.     PROPERTY TAXES. Tenant shall pay, or cause to be paid, before
delinquency, any and all taxes levied or assessed and which become payable
during the term hereof upon all Tenant's leasehold improvements, equipment,
furniture, fixtures, and personal property located in the Premises, except that
which has been paid for by Landlord and is the standard of the Building. In the
event any or all of the Tenant's leasehold improvements, equipment, furniture,
fixtures, and personal property shall be assessed and taxed with the Building,
Tenant shall pay to Landlord its share of such taxes within ten (10) days after
delivery to Tenant by Landlord of a statement in writing setting forth the
amount of such taxes applicable to Tenant's property.

21.     RULES AND REGULATIONS. Tenant shall faithfully observe and comply with
the rules and regulations that Landlord shall from time to time promulgate.
Landlord reserves the right from time to time to make all reasonable
modifications to said rules. The additions and modifications to those rules
shall be binding upon Tenant upon delivery of a copy of them to Tenant. Landlord
shall not be responsible to Tenant for the nonperformance of any said rules and
regulations by any other tenants or occupants.

22.     HOLDING OVER. If Tenant remains in possession of the Premises or any
part thereof after the expiration of the term hereof with the express written
consent of the Landlord, such occupancy shall be a tenancy from month to month
at a rental in the amount of the last monthly installment of Basic Rent or the
prevailing Adjusted Basic Rent, as the case may be, plus the last monthly
installment of Additional Rent and all other charges payable hereunder, and upon
all the terms hereof applicable to a month to month tenancy.

23.     ENTRY BY LANDLORD. Landlord reserves and shall at any and all times have
the right to enter the Premises, inspect the same, supply janitorial service and
any other service to be provided by Landlord to Tenant hereunder, to submit said
Premises to inspection by prospective purchasers or tenants, to post notices of
non-responsibility, and to alter, improve, or repair the Premises or the
Building that Landlord may deem necessary or desirable, without abatement or
rent and may for that purpose erect scaffolding and other necessary structures
where reasonably required by the character of the work to be performed, always
providing that the entrance to the Premises shall not be blocked thereby, and
further providing that the business of the Tenant shall not be interfered with
unreasonably. Tenant hereby waives any claim for damages or for any injury or
inconvenience to or interference with Tenant's business, any loss of occupancy
or quiet enjoyment of the Premises, and any other loss occasioned thereby. For
each of the aforesaid purposes, Landlord shall at all times have and retain a
key with which to unlock all of the doors in, upon, and about the Premises,
excluding Tenant's vaults, safes, and files, and Landlord shall have the right
to use any and all means which Landlord may deem proper to open said doors in an
emergency in order to obtain entry to the Premises without liability to Tenant
except for any failure to exercise due care for Tenant's property. Any entry to
the Premises obtained by Landlord by any of said means or otherwise shall not
under any circumstances be construed or deemed to be a forceable or unlawful
entry into or a detainer of the Premises, or an eviction of Tenant from the
Premises or any portion thereof.

24.     RECONSTRUCTION. In the event the Premises or the Building are damaged by
fire or other perils covered by extended coverage insurance, Landlord agrees to
forthwith repair the same, and this Lease shall remain in full force and effect,
except that Tenant shall be entitled to a proportionate reduction of the Basic
Rent or the prevailing Adjusted Basic Rent, as the case may be, while such
repairs are being made, such proportionate reduction to be based upon the extent
to which the making of such repairs shall materially interfere with the business
carried on by the Tenant in the Premises. If the damage is due to the fault or
neglect of Tenant or its employees, there shall be no abatement of rentals.




                                      -8-
<PAGE>   10

     In the event the Premises or the Building or a part thereof are damaged as
a result of any cause other than the perils covered by fire and extended
coverage insurance, then Landlord shall forthwith repair the same, provided the
extent of the destruction be less than ten (10%) per cent of the then full
replacement cost of the Premises or the Building. In the event the destruction
of the Premises or the Building is to an extent greater than ten (10%) per cent
of the full replacement cost, then Landlord shall have the option (i) to repair
or restore such damage with this Lease continuing in full force and effect, but
with the rentals to be proportionately reduced as hereinabove provided in this
Article, or (ii) give notice to Tenant at any time within sixty (60) days after
such damage terminating this Lease as of the date specified in such notice,
which date shall be no less than thirty (30) and no more than sixty (60) days
after the giving of such notice. In the event of giving such notice, this Lease
shall expire and all interest of the Tenant in the Premises shall terminate on
the date so specified in such notice and the rentals, reduced as hereinabove
provided in this Article, shall be paid up to date of said termination.

        Notwithstanding anything to the contrary contained in this Article,
Landlord shall not have any obligation whatsoever to repair, reconstruct, or
restore the Premises when the damage resulting from any casualty covered under
this Article occurs during the last twelve (12) months of the term of this Lease
or any extension thereof.

        Landlord shall not be required to repair any injury or damage by fire or
other cause or to make any repairs or replacements of any panels, decoration,
office fixtures, railings, floor covering, partitions, or any other property
installed in the Premises by Tenant.

        Tenant shall not be entitled to any compensation or damages from
Landlord for loss of the use of the whole or any part of the Premises, Tenant's
personal property, or any inconvenience or annoyance occasioned by such damage,
repair, reconstruction, or restoration.

25.     DEFAULT. In addition to any other act or event elsewhere stated in this
Lease which will cause a default hereunder, the occurrence of any one or more of
the following acts or events shall constitute a default and breach of this Lease
by Tenant:

        a.      The vacating or abandonment of the Premises by Tenant.

        b.      The failure by Tenant to make any payment of rent or any other
payment required to be made by Tenant hereunder, as and when due, where such
failure shall continue for a period of three (3) days after written notice
thereof by Landlord to Tenant.

        c.      The failure by Tenant to observe or perform any of the
covenants, conditions, or provisions of this Lease to be observed or performed
by the Tenant, other than described in subparagraph (b) of this Article, where
such failure shall continue for a period of thirty (30) days after written
notice thereof by Landlord to Tenant, provided, however, that if the nature of
Tenant's default is such that more than thirty (30) days are reasonably required
for its cure, then Tenant shall not be deemed to be in default if Tenant
commences such cure within said thirty (30) day period and thereafter diligently
prosecutes such cure to completion.

        d.      The making by Tenant of any general assignment or general
arrangement for the benefit of creditors; or the filing by or against Tenant of
a petition to have Tenant adjudged a bankrupt, or a petition or reorganization
or arrangement under any law relating to bankruptcy (unless, in the case of a
petition filed against Tenant, the same is dismissed within one hundred twenty
(120) days); or the appointment of a trustee or a receiver to take possession of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where possession is not restored to Tenant within thirty
(30) days; or the attachment, execution, or other judicial seizure of
substantially all or Tenant's assets located at the Premises, or of Tenant's
interest in this Lease, where such seizure is not discharged within thirty (30)
days.

26.     REMEDIES IN DEFAULT. In the event of any default or breach by Tenant,
Landlord may at any time thereafter, with or without notice or demand



                                      -9-
<PAGE>   11

and without limiting Landlord in the exercise of a right or remedy which
Landlord may have by reason of such default or breach:

        a.      Terminate Tenant's right to possession of the Premises by any
lawful means in which case this Lease shall terminate and Tenant shall
immediately surrender possession of the Premises to Landlord. In such event
Landlord stall be entitled to recover from Tenant all damages incurred by
Landlord by reason of Tenant's default including, but not limited to, the cost
of recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises; reasonable attorneys' fees
and costs; any real estate commissions and costs actually paid; the unpaid rent
for the balance of the term of the Lease or for the time the Premises are
vacant, whichever is shorter; that portion of the leasing commission paid by
Landlord and applicable to the unexpired term of this Lease. In the event Tenant
shall have abandoned the Premises, Landlord shall have the option of (i) taking
possession of the Premises and recovering from Tenant the amount specified in
this Article, or (ii) proceeding under the provisions of subparagraph (b) of
this Article.

        b.      Maintain Tenant's right to possession, in which case this Lease

rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

        c.      Pursue any other remedy now or hereafter available to Landlord

located.

27.     EMINENT DOMAIN. If more than twenty-five (25%) per cent of the Building

income, rental, award, or any interest therein whatsoever which may be paid or
made in connection with such public or quasi-public use or purpose, and Tenant
shall have no claim against Landlord for the value of any unexpired term of this

option to terminate this Lease and shall be entitled to the entire award as
above provided.

real property of which the Premises are a part.

29.     PARKING. Tenant shall have the right to use in common with other tenants
or occupants of the Building the parking facilities of the Building, if any,

31.     GENERAL PROVISIONS.

        a.      Plats and Riders. Clauses, plats and riders, if any, signed by
the Landlord and the Tenant and endorsed on or affixed to this Lease are a part
hereof.

        b.      Waiver. The waiver by Landlord of any term, covenant, or
condition herein contained shall not be deemed to be a waiver of such term,
covenant, or condition on any subsequent breach of the same or any other term,
covenant, or condition herein contained. The subsequent acceptance of rentals
hereunder by Landlord shall not be deemed to be a waiver of any preceding breach
by Tenant of any term, covenant, or condition of this Lease, regardless of
Landlord's knowledge of such preceding breach at the time of the acceptance of
such rentals.

        c.      Notices. All notices and demands which may or are to be required
or permitted to be given by either party to the other hereunder shall be in
writing. All notices and demands by the Landlord to the Tenant shall be sent by
United States mail, postage prepaid, addressed to the Tenant at the Premises, or
to such other place as Tenant may from time to time designate in a notice to the
Landlord. All notices and demands by the Tenant to the Landlord shall be sent by
United States mail, postage prepaid, addressed to the Landlord at the Office of
the Building, or to such other person or place as the Landlord may from time to
time designate in a notice to the Tenant.

        d.      Joint Obligation. If there be more than one Tenant, the
obligations hereunder imposed upon Tenants shall be joint and several.

        e.      Marginal Headings. The marginal headings and titles to the
Articles of this Lease are not a part of this Lease and shall have no effect
upon the construction or interpretation of any part hereof.

        f.      Time. Time is of the essence of this Lease and each and all of
its provisions in which performance is a factor.

        g.      Successors and Assigns. The covenants and conditions herein
contained, subject to the provisions as to assignment, apply to and bind the
heirs, successors, executors, administrators and assigns of the parties hereto.

        h.      Recordation. Neither Landlord nor Tenant shall record this Lease
or a short form memorandum hereof without the prior written consent of the other
party.

        i.      Quiet Possession. Upon Tenant paying the rent reserved hereunder
and observing and performing all of the covenants, conditions, and provisions on
Tenant's part to be observed and performed hereunder, Tenant shall have quiet
possession of the Premises for the entire term hereof, subject to all the
provisions of this Lease.

        j.      Late Charge. Tenant hereby acknowledges that late payment by
Tenant to Landlord of rent or other sums due hereunder will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed upon
Landlord by terms of any mortgage or trust deed covering the Premises or the
Building. Accordingly, if any amount(s) due from Tenant shall not be received by
Landlord or Landlord's designee within three (3) days after said amount is due,
then Tenant shall pay to Landlord a late charge equal to ten (10%) per cent of
such overdue amount(s). The parties hereby agree that such late charges
represent a fair and reasonable estimate of the cost that Landlord will incur by
reason of the late payment by Tenant. Acceptance of such late charges by the
Landlord shall in no event constitute a waiver of Tenant's default with respect
to such overdue amount, nor prevent Landlord from exercising any of the other
rights and remedies granted hereunder.

        k.      Prior Agreements. This Lease contains all of the agreements of
the parties hereto with respect to any matter covered or mentioned in this
Lease, and no prior agreements or understandings pertaining to any such matters
shall be effective for any purpose. No provision of this Lease may be amended or


                                      -11-
<PAGE>   13

added to except by an agreement in writing signed by the parties hereto or their
respective successors in interest. This Lease shall not be effective or binding
on any party until fully executed by both parties hereto.

        l.      Inability to Perform. This Lease and the obligations of the
Tenant hereunder shall not be affected or impaired because the Landlord is
unable to fulfill any of its obligations hereunder or is delayed in doing so, if
such inability or delay is caused by reason of strike, labor disputes, civil
disobedience, acts of God, or any other cause or condition beyond the reasonable
control of the Landlord.

        m.      Attorneys' Fees. In the event of any action or proceeding
brought by either party against the other under this Lease, the prevailing party
shall be entitled to recover all costs and expenses including the fees of its
attorneys in such action or proceeding in such amount as the court may adjudge
reasonable.

        n.      Sale of Building by Landlord. In the event of any sale of the
Building, Landlord shall be and is hereby entirely freed and relieved of all
liability under any and all of its covenants and obligations contained in or
derived from this Lease arising out of any act, occurrence, or omission
occurring after the consummation of such sale; and the purchaser, at such sale
or any subsequent sale of the Building shall be deemed, without any further
agreement between the parties or their successors in interest or between the
parties and any such purchaser, to have assumed and agreed to carry out any and
all of the covenants and obligations of the Landlord under this Lease.

        o.      Subordination, Attornment. Upon request of the Landlord, Tenant
will in writing subordinate its rights hereunder to the lien of any first
mortgage or first deed of trust to any bank, insurance company, or other leading
institution, now or hereafter in force against the Building or the underlying
land, and upon any buildings hereafter placed upon the land of which the
Premises are a part, and to all advances made or hereafter to be made upon the
security thereof. In the event any proceedings are brought for foreclosure, or
in the event of the exercise of the power of sale under any mortgage or deed of
trust made by the Landlord covering the Premises, the Tenant shall attorn to the
purchaser upon any such foreclosure or sale and recognize such purchaser as the
landlord under this Lease. The provisions of this Article to the contrary not
withstanding, and so long as Tenant is not in default hereunder, this Lease
shall remain in full force and effect for the full term hereof.

        p.      Name. Tenant shall not use the name of the Building or of the
development in which the Building is situated for any purpose other than as an
address of the business to be conducted by the Tenant in the Premises.

        q.      Separability. Any provision of this Lease which shall prove to
be invalid, void, or illegal shall in no way affect, impair, or invalidate any
other provision hereof and such other provisions shall remain in full force and
effect.

        r.      Cumulative Remedies. No remedy or election hereunder shall be
deemed exclusive but shall, wherever possible, be cumulative with all other
remedies at law or in equity.

        s.      Choice of Law. This Lease shall be governed by the laws of the
State in which the Premises are located.

        t.      Signs and Auctions. Tenant shall not place any sign upon the
Premises or Building or conduct any auction thereon without Landlord's prior
written consent.

If Tenant's Percentage Share of the Operating Expenses estimated in the Estimate
Statement exceeds the Operating Expenses Allowance then such excess amount shall
be divided into twelve (12) equal monthly installments and Tenant shall pay to
Landlord, concurrently with The regular monthly rent payment next due following
the receipt of such statement, an amount equal to one (1) monthly installment
multiplied by the number of months from January in the calendar year in which
said statement is submitted to the month of such payment, both months inclusive.
Subsequent installments shall be paid concurrently with the regular monthly rent
payments for the balance of the calendar year and shall continue until the next
calendar year's Estimate Statement is rendered. By the first day of June of each
succeeding calendar year during the term of this Lease, Landlord shall endeavor
to deliver to Tenant a statement ("Actual Statement") wherein Landlord shall
state the actual Operating Expenses for the preceding calendar year. If the
Actual Statement reveals a greater increase in Tenant's Percentage Sham of
Operating Expenses than was estimated by Landlord in the Estimated Statement
delivered as provided herein, then upon receipt of the Actual Statement from
Landlord, Tenant shall pay a lump sum equal to said total increase over the
Operating Expenses Allowance, less the total of the monthly installments of
increases set forth on the Estimate Statement which were paid in the previous
calendar year. If, in any calendar year, Tenant's Percentage Share of Opening
Expenses is less than the preceding calendar year. then upon receipt of
Landlord's Actual Statement, any overpayment made by Tenant on the monthly
installment basis provided above shall be credited toward the next monthly rent
falling due and the monthly installment of Tenant's Percentage Share or
Operating Expenses to be paid pursuant to the then current Estimate Statement
shall be adjusted to reflect such lower expenses for the most recent calendar
year, or if this Lease has been terminated, such excess shall be credited
against any amount which Tenant owes Landlord pursuant to this Lease and, to the
extent all amounts which Tenant owes Landlord pursuant to this Lease have been
paid, Landlord shall promptly pay such excess to Tenant. Any delay or failure by
Landlord in delivering any estimate or statement pursuant to this Paragraph
shall not constitute a waiver of its right to require an increase in rent nor
shall it relieve Tenant of its obligations pursuant to this Paragraph, except
that Tenant "Shall not be obligated to make any payments based on such estimate
or statement until ten (10) days after receipt of such estimate or statement.

        (c)     Even though the term has expired and Tenant has vacated the
Premises; when the final determination is made of Tenant's Percentage Share of
Operating Expenses for the year in which this Lease terminates, Tenant shall
immediately pay any increase due over the estimated expenses paid and conversely
any overpayment made in the event said expenses decrease shall be immediately
rebated by Landlord to Tenant.

rental payable by Tenant shall in no event be less than the rent specified in
Paragraph 5 hereof.

in default, or for the payment of any other amount which Landlord may spend or
become obligated to spend by reason of Tenant's default or to compensate
Landlord for any loss or damage which Landlord may suffer by reason of Tenant's
default. If any portion of said deposit is so used or applied, Tenant shall,
within ten (10) days after demand therefor, deposit cash with Landlord in an
amount sufficient to restore the Security Deposit to its original amount and
Tenant's failure to do so shall be a material breach of this Lease. Landlord

funds. and Tenant shall not be entitled to interest on such Security Deposit. If
Tenant shall fully and faithfully perform every provision of this Lease to be
performed by it, the Security Deposit or any balance thereof shall be returned
to Tenant (or, at Landlord's option, to the last assignee of Tenant's interests
hereunder) at the expiration of the Lease term, provided that Landlord may
retain the Security Deposit until such time as any amount due from Tenant in
accordance with Paragraph 5 and 6 hereof has been determined and paid in full.

Landlord deposits with the purchaser thereof the then unappropriated funds
deposited by Tenant as aforesaid, thereupon Landlord shall be discharged from

more than one person or entity constitutes the "Tenant" under this Lease,
service of any notice upon any one of said persons or entities shall be deemed
as service upon all of said persons or entities.

        10.     Brokers. The parties recognize that the brokers who negotiated

before delinquency, taxes levied against any personal property or trade fixtures
placed by Tenant in or about the Premises. If any such taxes on Tenant's
personal property or trade fixtures are levied against Landlord or Landlord's
property or if the assessed value of the Premises is increased by the inclusion
therein of a value placed upon such personal property or trade fixtures of
Tenant and if Landlord, after written notice to Tenant, pays the taxes based
upon such increased assessments, which Landlord shall have the right to do
regardless of the validity thereof, but only under proper protest if requested
by Tenant, Tenant shall upon demand repay to Landlord the taxes levied against
Landlord, or the proportion of such taxes resulting from such increase in the
assessment; provided that in any such event. at Tenant's sole cost and expense,

<PAGE>   35



valuation higher than the valuation at which Aggregate Improvements conforming
to Landlord's "Building Standard" in other space in the Building are assessed,
then the real property taxes and assessment levied against Landlord or the
property by reason of such excess assessed valuation shall be deemed to be taxes
levied against personal property of Tenant and shall be governed by the
provisions of Subparagraph 12(a), above. If the records of the County Assessor
are available and sufficiently detailed to serve as a basis for determining
whether said Aggregate Improvements are assessed at a higher valuation than
Landlord's "Building Standard," such records shall be binding on both Landlord
and Tenant. If the records of the County Assessor are not available or
sufficiently detailed to serve as a basis for making said determination, the
actual cost of construction shall be used.

nor any agent of Landlord has made any representation or warranty with respect
to the Premises or the Building or with respect to the suitability of either for
the conduct of Tenant's business. The taking of possession of the Premises by
Tenant shall conclusively establish that the Premises and the Building were at
such time in satisfactory condition, however, occupancy and rent commencement
will  not interfere with Landlord's obligation to complete Tenant Improvements.

as Exhibit "D" shall constitute a specific acknowledgment and acceptance of the
various start-up inconveniences that may be associated with the use of the
Building Common Areas such as certain construction obstacles including
scaffolding, delays in the use of freight elevator service, certain elevators
not being available to Tenant, the passage of work crews using elevators, uneven
air conditioning service, and other typical conditions incident to recently
constructed office buildings. Further, Tenant's execution of said Notice shall
constitute an acknowledgment, in light of the practical impossibility of
ensuring that every floor slab has been installed with absolutely no deflection,
that all wood floor coverings, wood paneling, and similar interior Aggregate
Improvements have been and/or will be designed to accommodate the actual floor
slab deflection unique to each particular area of the Premises to be so
improved.

        14.     Alterations. 

        (a)     Tenant may, at any time and from time to time during the term of
this Lease, at its sole cost and expense, make alterations, additions,
installations, substitutions, improvements and decorations (hereinafter
collectively called "Changes") in and to the Premises, excluding structural
changes, on the following conditions, and providing such Changes will not result
in a violation of or require a change in the Certificate of Occupancy applicable
to the Premises:

                (i)     The outside appearance, character or use of the Building
                shall not be affected, and no Changes shall weaken or impair the
                structural strength or, in the opinion of Landlord, lessen the
                value of the Building or create the potential for unusual
                expenses to be incurred upon the removal of Changes and the
                restoration of the Premises upon the termination of this Lease.

                (ii)    No part of the Building outside of the Premises shall be
                physically affected.

                (iii)   The proper functioning of any of the mechanical,
                electrical, sanitary and other service systems or installations
                of the Building ("Service Facilities") shall not be adversely
                affected and there shall be no construction which might
                interfere with Landlord's free access to the Service Facilities
                or interfere with the moving of Landlord's equipment to or from
                the enclosures containing the Service Facilities.

                (iv)    In performing the work involved in making such Changes,
                Tenant shall be bound by and observe all of the conditions and
                covenants contained in this Paragraph.

                (v)     All work shall be done at such times and in such manner
                as Landlord from time to time may designate.

                (vi)    Tenant shall not be permitted to install and make part
                of the Premises any materials, fixtures or articles which are
                subject to liens, conditional sales contracts or chattel
                mortgages.

                (vii)   At the date upon which the term of this Lease shall end,
                or the date of any earlier termination of this Lease, Tenant
                shall on Landlord's written request restore the Premises to
                their condition prior to the making of any Changes permitted by
                this Paragraph, reasonable wear and tear excepted.

        (b)     Before proceeding with any Change (exclusive of changes to items
constituting Tenant's personal property), Tenant shall submit to Landlord plans
and specifications for the work to be done, which shall require Landlord's
written approval. Landlord shall then prepare or cause to be prepared, at
Tenant's expense, mechanical, electrical and plumbing drawings and may confer
with consultants in connection with the preparation of such drawings and may
also submit to such consultant(s) any of the plans prepared by Tenant. If
Landlord or such consultant(s) shall disapprove of any of the Tenant's plans
Tenant shall be advised of the reasons of such disapproval. In any event, Tenant
agrees to pay to Landlord, as additional rent, the cost of such consultation and
review immediately upon receipt of invoices either from Landlord or such
consultant(s). Any Change for which approval has been received shall be
performed strictly in accordance with the approved plans and specifications, and
no amendments or additions to such plans and specifications shall be made
without the prior written consent of Landlord.

        (c)     If the proposed Change requires approval by or notice to the
lessor of a superior lease or the holder of a mortgage, no Change shall be
proceeded with until such approval has been received, or such notice has been
given, as the case may be, and all applicable conditions and provisions of said
superior lease or mortgage with respect to the proposed Change or alteration
have been met or complied with at Tenant's expense; and Landlord, if it approves
the Change, will request such approval or give such notice, as the case may be.

the approval by or notice to the lessor of a superior lease or the holder of a
superior mortgage has been received or given, as the case may be, Tenant shall
enter into an agreement for the performance of the work to be done pursuant to
this Paragraph with Landlord's contractor. In any event, Tenant agrees to pay to
Landlord, at Landlord's option, in advance of construction based upon Landlord's
cost estimates, or as additional rent, the cost of such construction immediately
upon receipt from Landlord of invoices from time to time during the course of
such construction. All costs and expenses incurred in Changes shall be paid by
Tenant within seven (7) days after each billing by Landlord or any such
contractor or contractors. If Landlord approves the construction of specific
interior improvements in the Premises by contractors or mechanics selected by
Tenant and approved by Landlord, then Tenant's contractors shall obtain on
behalf of Tenant and at Tenant's sole cost and expense, (i) all necessary
governmental permits and certificates for the commencement and prosecution of
Tenant's Changes and for final approval thereof upon completion, and (ii) a
completion and lien indemnity bond, or other surety, satisfactory to Landlord,
for the Changes. In the event Tenant shall request any changes in the work to be

the changes initially submitted by Tenant.

        (e)     Tenant shall pay to Landlord for Landlord's services in the
event Landlord performs as a general contractor in connection with the work

requirements of all governmental authorities, agencies, offices, departments,

of any other tenant in the Building nor delay or impose any additional expense
upon Landlord in construction, maintenance or operation of the Building, and
shall be performed by Contractors or mechanics approved by Landlord and
submitted to Tenant pursuant to this Paragraph, who shall coordinate their work
in cooperation with any other work being performed with respect to the Building.

to the end of the term, require Tenant to remove all partitions, counters,
railings and the like installed by Tenant, and Tenant shall repair any damage to
the Premises arising from such removal or, at Landlord's option, shall pay to
the Landlord all of Landlord's costs of such removal and repair.

        (h)     All articles of personal property and all business and trade
fixtures, machinery and equipment, furniture and movable partitions owned by
Tenant or installed by Tenant at its expense in the Premises shall be and remain
the property of Tenant and may be removed by Tenant at any time during the lease
term provided Tenant is not in default hereunder, and provided further that
Tenant shall repair any damage caused by such removal. If Tenant shall fail to

for loss thereof, and Tenant agrees to pay Landlord upon demand any and all
expenses incurred in such removal, including court costs and attorneys' fees and
storage charges on such effects for any length of time that the same shall be in
Landlord's possession or Landlord may, at its option, without notice, sell said
effects, or any of the same, at private sale and without legal process, for such
price as Landlord may obtain and apply the proceeds of such sale upon any
amounts due under this Lease from Tenant to Landlord and upon the expense
incident to the removal and sale of said effects.

        (i)     Subject to Landlord's agreement to minimize any disturbance of
Tenant's use of the Premises, Landlord reserves the right at any time and from
time to time without the same constituting an actual or constructive eviction
and without incurring any liability to Tenant therefor or otherwise affecting
Tenant's obligations under this Lease, to make such changes, alterations,
additions, improvements, repairs or replacements in or to the Site or the
Building (including the Premises if required so to do by any law or regulation)
and the fixtures and equipment thereof, as well as in or to the street
entrances, halls, passages and stairways thereof, to change the name by which
the Building is commonly known except as controlled by the signage provision,
Rider #5, between Landlord and Tenant in that Lease dated April 22, 1991, as
Landlord my deem necessary or desirable. Nothing contained in this Paragraph 14
shall be deemed to relieve Tenant of any duty, obligation or liability of Tenant
with respect to making any repair, replacement or improvement or complying with
any law, order or requirement of any government or other authority and nothing
contained in this Paragraph 14, shall be deemed or construed to impose upon
Landlord any obligation, responsibility or liability whatsoever, for the care,
supervision of repair of the Building or any part thereof other than as
otherwise provided in this Lease.

        15.     Repairs.

        (a)     By entry hereunder, Tenant accepts the Premises as being in good
and sanitary order, condition and repair, however, occupancy and rent
commencement will not interfere with Landlord's obligation to complete Tenant
Improvements. Tenant shall, when and if needed or whenever requested by Landlord
to do so, at Tenant's sole cost and expense, maintain and make all repairs to
the Premises and every part thereof, to keep, maintain and preserve the Premises
in first class condition, excepting ordinary wear and tear. Any such maintenance
and repairs shall be performed by Landlord's contractor, or a Landlord's
approved contractor or contractors. All costs and expenses incurred in such
maintenance and repair shall be paid by Tenant within seven (7) days after
billing by Landlord or such contractor or contractors. Tenant shall upon the
expiration or sooner termination of the term hereof surrender the Premises to
Landlord in the same condition as when received, reasonable wear and tear
excepted. Landlord shall have no obligation to alter, remodel, improve, repair,
decorate or paint the Premises or any part thereof and the parties hereto affirm
that Landlord has made no representations to Tenant respecting the condition of
the Premises or the Building except as specifically herein set forth.

        (b)     Anything contained in Subparagraph 15 a above to the contrary
notwithstanding, Landlord shall repair and maintain the structural portions of
the Building, including the basic plumbing, heating, ventilating, air
conditioning and electrical systems installed or furnished by Landlord, unless
such maintenance and repairs are caused in part or in whole by the act, neglect,
fault of or omission of any duty by Tenant, its agents, servants, employees or
invitees, in which case Tenant shall pay to Landlord as additional rent, the
reasonable cost of such maintenance and repairs. Landlord shall not be liable
for any failure to make any such repairs, or to perform any maintenance unless
such failure shall persist for an unreasonable time after written notice of the
need of such repairs or maintenance is given to Landlord by Tenant. Except as
provided in Paragraph 22 hereof there shall be no abatement of rent and no
liability of Landlord by reason of any injury to or interference with Tenant's
business arising from the making of any repairs, alterations or improvements in
or to any portion of the Building or the Premises or in or to fixtures,
appurtenances and equipment therein. Tenant waives the right to make repairs at
Landlord's expense under any law, statute or ordinance now or hereafter in
effect. Notwithstanding anything to the contrary contained in Subparagraphs (a)
and (b) of this Paragraph 15, Tenant shall maintain and repair at its sole cost
and expense, and with maintenance contractors approved by Landlord, all non-base
building facilities, including lavatory, shower, toilet, washbasin and kitchen
facilities and heating and air conditioning systems, including all plumbing
connected to said facilities or systems installed by Tenant or on behalf of
Tenant or existing in the Premises at the time of delivery of possession of the
Premises to Tenant by Landlord. The provisions of the immediately preceding
sentence shall not apply to the basic heating and air conditioning system
provided by Landlord to all tenants of the Building.

        16.     Liens. Tenant shall not permit any mechanic's, materialmen's or
other liens to be filed against the real property of which the Premises form a
part nor against the Tenant's leasehold interest in the Premises. Landlord shall
have the right at all reasonable times to post and keep posted on the Premises
any notices which it deems necessary for protection from such liens. If any such
liens are filed, Landlord may, without waiving its rights and remedies based on
such breach of Tenant and without releasing Tenant from any of its obligations,
cause such liens to be released by any means it shall deem proper, including
payment in satisfaction of the claim giving rise to such lien. Tenant shall pay
to Landlord at once, upon notice by Landlord, any sum paid by Landlord to remove
such liens, together with interest at the maximum rate per annum permitted by
law from the data of such payment by Landlord.

        17.     Entry by Landlord. Subject to Landlord's agreement to minimize
any disturbance of Tenant's use of the Premises by exercise of the following
rights, Landlord reserves and shall at any and all times have the right to enter
the Premises to inspect the same, to supply janitor service and any other
provided by Landlord to Tenant hereunder, to submit said Premises to prospective
purchasers or, during the last six (6) months of the term of this Lease, to
prospective tenants, to post notices of nonresponsibility, to alter, improve or
repair the Premises or any other portion of the Building, all without being
deemed guilty of any eviction of Tenant and without abatement of rent, and may,
in order to carry out such purposes, erect scaffolding and other necessary
structures where reasonably required by the character of the work to be
performed, provided that the business of Tenant shall be interfered with as
little as is reasonably practicable. Tenant hereby waives any claim for damages
for any injury or inconvenience to or interference with Tenant's business, any
loss of occupancy or quiet enjoyment of the Premises, and any other loss
occasioned thereby. For each of the aforesaid purposes, Landlord shall at all
times have and retain a key with which to unlock all of the doors in, upon and
about the Premises, excluding Tenant's vaults and safes, and Landlord shall have
the means which Landlord may deem proper to open said doors in an emergency in
order to obtain entry to the Premises, and any entry to the Premises obtained by
Landlord by any of said means, or otherwise, shall not under any circumstances
be construed or deemed to be a forcible or unlawful entry into, or a detainer
of, the Premises, or an eviction of Tenant from the Premises or any portion
thereof, and any damages caused on account thereof shall be paid by Tenant. It
is understood and agreed that no provision of this Lease shall be construed as
obligating Landlord to perform any repairs, alterations or decorations except as
otherwise expressly agreed herein to be performed by Landlord. Landlord shall
attempt in the exercise of its rights under this Paragraph 17 to minimize any
disturbance of Tenant's use and possession of the Premises and to provide as
much notice to Tenant as may be reasonably possible prior to any such exercise
of Landlord's rights under this Paragraph 17.

        18.     Utilities and Services. Provided that Tenant is not in default
hereunder, Landlord agrees, during the Lease term, to furnish to the Premises as
part of the Operating Expenses during those hours set forth in the Rules and
Regulations as defined in Paragraph 31 hereof, as may be amended in writing by
Landlord from time to time during the term of this Lease and delivered to
Tenant, reasonable quantities of electric current for normal lighting and
fractional horsepower office machines, water for lavatory and drinking purposes,
heat and air conditioning required in Landlord's judgment for the comfortable
use and occupation of the Premises, janitorial service (including washing of
windows with reasonable frequency as determined by Landlord) and elevator
service by non-attended automatic elevators. Landlord shall not be liable for,
and Tenant shall not be entitled to any abatement or reduction of rent by reason
of Landlord's failure to furnish any of the foregoing when such failure is
caused by accident, breakage, repairs, strikes, lockouts or other labor
disturbances or labor disputes of any character, or for any other causes. If
Tenant requires or utilizes more water or electric power than is considered
reasonable or normal by



                                        9

Landlord, Landlord may at its option require Tenant to pay, as additional rent,
the cost, as fairly determined by Landlord, incurred by such extraordinary
usage. In addition, Landlord may install separate meter(s) for the Premises, at
Tenant's sole expense, and Tenant thereafter shall pay all charges of the
utility providing service. Tenant specifically undertakes to install and
maintain at Tenant's cost such fire protection equipment including, without
limitation, emergency lighting as required by any governmental authority or
insurer, and if so required, Tenant shall appoint one of Tenant's personnel to
coordinate with the fire protection facilities and personnel of Landlord. Any
incandescent light bulbs used in the Premises shall be paid for the Tenant. Upon
Tenant's request, Landlord's personnel shall install incandescent light bulbs or
other Building Nonstandard bulbs in the Premises. Tenant agrees to pay Landlord
upon demand Landlord's cost for all such incandescent light bulbs installed or
other Building Nonstandard improvements including but not limited to metallic
trim, wood floor covering, glass panels, windows, partitions, kitchens and
executive washrooms in the Premises. Landlord shall not be responsible in any
manner for said maintenance, cleaning and repair.

        19.     Indemnification. To the fullest extent permitted by law Tenant
hereby agrees to defend, indemnify and hold Landlord harmless against and from
any and all claims arising from Tenant's use of the Premises or the conduct of
its business or from any activity, work, or thing done, permitted or suffered by
Tenant, its agents, contractors, employees or invitees in or about the Premises
or elsewhere, and hereby agrees to further indemnify and hold harmless Landlord
against and from any and all claims arising from any breach or default in the
performance of any obligation on Tenant's part to be performed under the terms
of this Lease or arising from any act, neglect, fault or omission of Tenant, or
of its agents, employees or invitees, and from and against all costs, attorneys'
fees, expenses and liabilities incurred in or about the Premises for such claim
or any action or proceeding brought thereon. In case any action or proceeding is
brought against Landlord by reason of any such claim, Tenant upon notice from
Landlord hereby agrees to defend the same at Tenant's expense by counsel
approved in writing by Landlord. Tenant, as a material part of the consideration
to Landlord, hereby assumes all risk of damage to property or injury to persons
in, upon or about the Premises from any cause whatsoever except that which is
caused by the failure of Landlord to observe any of the terms and conditions of
this Lease and such failure has persisted for an unreasonable period of time
after written notice of such failure, and Tenant hereby waives all its claims in
respect thereof against Landlord.

        20.     Damage to Tenant's Property. Notwithstanding the provisions of
Paragraph 19 to the contrary, Landlord or its agents shall not be liable for any
damage to property entrusted to employees of the Building, nor for loss of or
damage to any property by theft or otherwise, nor for any injury or damage to
persons or property resulting from fire, explosion, falling plaster, steams,
gas, electricity, water or rain which may leak from any part of the Building or
from the pipes, appliances or plumbing works therein or from the roof, street or
sub-surface or from any other place or resulting from dampness or any other
patent or latent cause whatsoever. Landlord or its agents shall not be liable
for interference with the light or other incorporeal hereditaments. Tenant shall
give prompt notice to Landlord in case of fire or accidents in the Premises or
in the Building or of defects therein or in the fixtures or equipment located
therein.

        21.     Insurance.

        (a)     During the term hereof, Tenant, at its sole expense, shall
obtain and keep in force the following insurance:

                (i)     All Risk insurance upon property owned by Tenant and
                located in the Building or for which Tenant is legally liable.
                Aggregate Improvements (other than "Building Standard Work" as
                described in Subparagraph 1(1) hereof), and alterations, in an
                amount not less than ninety percent (90%) of the full
                replacement cost thereof. All such insurance policies shall name
                Tenant and Landlord as named insured thereunder and, at
                Landlord's request, shall name Landlord's mortgagees (and, if
                applicable, ground or primary lessors) as loss payees
                thereunder, all as their respective interests may appear.
                Landlord will not be required to carry insurance of any kind on
                any "Building Non-Standard Work", as described in Subparagraph
                1(m) hereof, on Tenant's furniture or furnishings, or on any of
                Tenant's fixtures, equipment, improvements, or appurtenances
                under this Lease, and Landlord shall not be obligated to repair
                any damage thereto or replace the same.

                (ii)    Comprehensive general liability insurance coverage,
                including personal injury, bodily injury, broad form property
                damage, operations hazard, owner's protective coverage,
                contractual liability, and products and completed operations
                liability, in limits not less than $2,000,000 inclusive. All
                such insurance policies shall name Tenant as named insured
                thereunder and shall name Landlord and landlord's mortgagees
                (and, if applicable, ground or primary lessors) as additional
                insured thereunder, all as their respective interests may
                appear.

                (iii)   Workers' Compensation and Employer's Liability
                insurance, with a waiver of subrogation endorsement, in form and
                amount satisfactory to Landlord.

                (iv)    [COPY DELETED]

                (v)     Liquor liability insurance coverage in limits of not
                less than Five hundred Thousand Dollars ($5000,000) if at any
                time during the term or on any occurrence hereof of any
                alcoholic beverages of any nature are served on the Premises.

                (vi)    Any other form or forms of insurance as Tenant,
                Landlord, or Landlord's mortgagees or ground or primary lessors
                may reasonably require from time to time in form, in amounts,
                and for insurance risks against which a prudent tenant of a
                comparable size and in a comparable business would protect
                itself.

                                       10



<PAGE>   40



        (b)     All policies shall be issued by insurers that are acceptable to
Landlord and in form satisfactory from time to time to Landlord. Tenant will
deliver certificates of insurance to Landlord as soon as practicable after the
placing of the required insurance, but not later than ten (10) days prior to the
date Tenant takes possession of all or any pan of the Premises. All policies
shall contain an undertaking by the insurers to notify Landlord and Landlord's
mortgagee (and, if applicable, ground or primary lessors) in writing, not less
than thirty (30) days before any material change, reduction in coverage,
cancellation, or other termination thereof. Ten (10) days prior to the
expiration of any insurance policy, Tenant will provide Landlord with a
Certificate of Insurance extending the term of the original policy or a
certified copy of a new policy extending the required coverage.

        (c)     During the Term, Landlord shall insure the Building and the
Building Standard Work (excluding any property which Tenant is obligated to
insure under Subparagraph 21(a) hereof) against damage with All Risk insurance
and public liability insurance, all in such amounts and with such deductions as
Landlord considers appropriate, Landlord may, but shall not be obligated to,
obtain and carry any other form or forms of insurance as it or Landlord's
mortgagees may determine advisable. Notwithstanding any contribution by Tenant
to the cost of insurance premiums, as provided herein, Tenant acknowledges that
it has no right to receive any proceeds from any insurance policies carried by
Landlord.

        (d)     Tenant will not keep, use, sell, or offer for sale in, or on,
the Premises any article which may be prohibited by any insurance policy
periodically in force covering the Building and the Building Standard Work.
Tenant shall promptly comply with all reasonable requirements of the insurance
authority or any present or future insurer relating to the Premises.

        (e)     If any of Landlord's insurance policies shall be cancelled or
cancellation shall be threatened or the coverage thereunder reduced or
threatened to be reduced in any way because of the use of the Premises or any
part thereof by Tenant or any assignee or sub-tenant of Tenant or by anyone
Tenant permits on the Premises and, if Tenant fails to remedy the condition
giving rise to such cancellation, threatened cancellation, reduction of
coverage, threatened reduction of coverage, increase in premiums, or threatened
increase in premiums, within 48 hours after notice thereof, Landlord may, at its
option, either terminate this Lease or enter upon the Premises and attempt to
remedy such condition, and Tenant shall promptly pay the cost thereof to
Landlord as additional rent. Landlord shall not be liable for any damage or
injury caused to any property of Tenant or of others located on the Premises
resulting from such entry. If Landlord is unable, or elects not, to remedy such
condition, then Landlord shall have all of the remedies provided for in this
Lease in the event of a default by Tenant. Notwithstanding the foregoing
provisions of this Subparagraph 21(e), if Tenant fails to remedy as aforesaid,
Tenant shall be in default of its obligation hereunder and Landlord shall have
no obligation to remedy such default.

        (f)     All policies covering real or personal property which either
party obtains affecting the Premises shall include a clause or endorsement
denying the insurer any rights of subrogation against the other party to the
extent rights have been waived by the insured before the occurrence of injury or
loss, if same are obtainable without unreasonable cost. Landlord and Tenant
waive any rights of recovery against the other for injury or loss due to hazards
covered by policies of insurance containing such a waiver of subrogation clause
or endorsement, to the extent of the injury or loss covered thereby.

        22.     Damage or Destruction.

        (a)     In the event the Building and/or the Building Standard Work or
any insured alterations are damaged by fire or other perils covered by
Landlord's extended coverage insurance to an extent not exceeding twenty-five
percent (25%) of the full insurable value thereof and if the damage thereto is
such that the Building and/or the Building Standard Work and any insured
alterations may be repaired, reconstructed or restored within a period of ninety
(90) days from the date of the happening of such casualty and Landlord will
receive insurance proceeds sufficient to cover the cost of such repairs,
Landlord shall commence and proceed diligently with the work of repair,
reconstruction and restoration and the Lease shall continue in full force and
effect. If such work or repair, reconstruction and restoration is such as to
require a period longer than ninety (90) days or exceeds twenty-five percent
(25%) of the full insurable value thereof, or if said insurance proceeds will
not be sufficient to cover the cost of such repairs, Landlord either may elect
to so repair, reconstruct or restore the Building and/or Building Standard Work
and any insured alterations and the Lease shall continue in full force and
effect or Landlord may elect not to repair, reconstruct or restore the Building
and/or Building Standard Work and any insured alterations and the Lease shall in
such event terminate. Under any of the conditions of this Subparagraph 22(a),
Landlord shall give written notice to Tenant of its intention within thirty (30)
days from the date of such event of damage or destruction. In the event Landlord
elects not to restore said Building and/or Building Standard Work and any
insured alterations, this Lease shall be deemed to have terminated as of the
date of such partial destruction.

        (b)     Upon any termination of this lease under any of the provisions
of this Paragraph 22, the parties shall be released thereby without further
obligation to the other from the date possession of the Premises is surrendered
to Landlord except for items which have therefore accrued and are then unpaid.

        (c)     In the event of repair, reconstruction and restoration by
Landlord as herein provided, the rent provided to be paid under this Lease shall
be abated proportionately with the degree to which Tenant's use of the Premises
is impaired during the

                                       11
<PAGE>   41



period of such repair, reconstruction or restoration. Tenant shall not be
entitled to any compensation or damages for loss in the use of the whole or any
part of the Premises and/or any inconvenience, annoyance or loss of business
occasioned by such damage, repairs reconstruction or restoration.

        (d)     Tenant shall not be released from any of its obligations under
this Lease except to the extent and upon the conditions expressly stated in this
Paragraph 22. Notwithstanding anything to the contrary contained in this
Paragraph 22, should Landlord be delayed or prevented from repairing or
restoring the damaged Premises within one (1) year after the occurrence of such
damage or destruction by reason of acts of God, war, governmental restrictions,
inability to procure the necessary labor or materials, or other cause beyond the
control of Landlord, Landlord shall be relieved of its obligation to make such
repairs or restoration and Tenant shall be released from its obligations under
this Lease as of the end of said year.

        (e)     In the event that damage is due to any cause other than fire or
other peril covered by extended coverage insurance, Landlord may elect to
terminate this Lease.

        (f)     It is hereby understood that if Landlord is obligated to or
elects to repair or restore as herein provided, Landlord shall be obligated to
make repairs or restoration only of those portions of the Building and the
Premises which were originally provided at Landlord's expense or which were
insured by either party and the proceeds of such insurance have been received by
Landlord, and the repair and restoration of items not provided at Landlord's
expense shall be the obligation of Tenant.

        (g)     Notwithstanding anything to the contrary contained in this
Paragraph 22, Landlord shall not have any obligations whatsoever to repair,
reconstruct or restore the Premises when the damage resulting from any casualty
covered under this Paragraph 22 occurs during the last twelve (12) months of the
term of this Lease or any extension hereof.

        (h)     The provisions of California Civil Code 1932, Subsection 2, and
1933, Subsection 4, are hereby waived by Tenant.

        23.     Eminent Domain.
                  

        (a)     In case the whole of the Premises, or such part thereof as shall
substantially interfere with Tenant's use and occupancy thereof, shall be taken
for any public or quasi-public purpose by any lawful power or authority by
exercise of the right of appropriation, condemnation or eminent domain, or sold
to prevent such taking, either party shall have the right to terminate this
Lease effective as of the date possession is required to be surrendered to said
authority. Tenant shall not assert any claim against Landlord or the taking
authority for any compensation because of such taking, and Landlord shall be
entitled to receive the entire amount of any award without deduction for any
estate or interest of Tenant. In the event the amount of property or the type of
estate taken shall not substantially interfere with the conduct of Tenant's
business, Landlord shall be entitled to the entire amount of the award without
deduction for any estate or interest of Tenant, and landlord at his option may
terminate this Lease. If Landlord does not so elect, Landlord shall promptly
proceed to restore the Premises to substantially their same condition prior to
such partial taking, and a proportionate allowance shall be made to Tenant for
the rent corresponding to the time during which, and to the part of the Premises
of which, Tenant shall be so deprived on account of such taking and restoration.
Nothing contained in this Paragraph shall be deemed to give Landlord any
interest in any award separately made to Tenant for the taking of personal
property and trade fixtures belonging to Tenant or for moving costs incurred by
Tenant in relocating Tenant's business.

        (b)     In the event of taking of the Premises or my part thereof for
temporary use, (i) this Lease shall be and remain unaffected thereby and rent
shall not abate, and (ii) Tenant shall be entitled to receive for itself such
portion or portions of any award made for such use with respect to the period of
the taking which is within the term, provided that if such taking shall remain
in force at the expiration or earlier termination of this Lease, Tenant shall
then pay to Landlord a sum equal to the reasonable cost of performing Tenant's
obligations under Paragraph 15 with respect to surrender of the Premises and
upon such payment shall be excused from such obligations. For purpose of this
Subparagraph 23(b), a temporary taking shall be defined as a taking for a period
of 270 days or less.

        24.     Bankruptcy. If Tenant shall file a petition in bankruptcy under
any Chapter of federal bankruptcy law as then in effect, or if Tenant be
adjudicated a bankrupt in involuntary bankruptcy proceedings and such
adjudication shall not have been vacated within thirty (30) days from the date
thereof, or if a receiver or trustee be appointed of Tenant's property and the
order appointing such receiver or trustee not be set aside or vacated within
thirty (30) days after the entry thereof, or if Tenant shall assign Tenant's
estate or effects for the benefit of creditors, or if this Lease shall otherwise
by operation of law pass to any person or persons other than Tenant, then and in
any such event Landlord may, if Landlord so elects, with or without notice of
such election and with or without entry or action by Landlord, forthwith
terminate this Lease. Notwithstanding any other provisions of this Lease,
Landlord, in addition to any and all rights and remedies allowed by law or
equity, shall upon such termination be entitled to recover damages in the amount
provided in Subparagraph 25(b) below and neither Tenant nor any person claiming
through or under Tenant or by virtue of any statute or order of any court shall
be entitled to possession of the Premises but shall forthwith quit and surrender
the Premises to Landlord. Nothing herein contained shall limit or prejudice the
right of Landlord to prove and obtain as damages by reason of any such
termination an amount equal to the maximum allowed by any statute or rule of law
in effect at the time when, and governing the proceedings in which, such damages
are to be proved, whether or not such amount be greater, equal to, or less than
the amount of damages recoverable under the provisions of this Paragraph 24.

        25.     Defaults and Remedies.

        (a)     The occurrence of any one or more of the following events shall
constitute a default hereunder by Tenant:



                                       12



<PAGE>   42



                (i)     The vacation or abandonment of the Premises by Tenant.
                Abandonment is herein defined to included, but is not limited,
                to, any absence by Tenant from the Premises for five (5) days or
                longer while in default of any provision of this Lease.

                (ii)    The failure by Tenant to make any payment of rent or
                additional rent or any other payment required to be made by
                Tenant hereunder, as and when due.

                (iii)   The failure by Tenant to observe or perform any of the
                express or implied covenants or provisions of this Lease to be
                observed or performed by Tenant, other than as specified in
                Subparagraph 25(a)(i) or (ii) above, where such failure shall
                continue for a period of ten (10) days after written notice
                thereof from Landlord to Tenant; provided, however, that any
                such notice shall be in lieu of, and not in addition to, any
                notice required under California Code of Civil Procedure 1161;
                provided, further, that if the nature of Tenant's default is
                such that more than ten (10) days are reasonably required for
                its cure, then Tenant shall not be deemed to be in default if
                Tenant shall commence such cure within said ten-day period and
                thereafter diligently prosecute such cure to completion, which
                completion shall occur not later than sixty (60) days from the
                date of such notice from Landlord.

                (iv)    (1)The making by Tenant of any general assignment for
                the benefit of creditors; (2) the filing by or against Tenant of
                a petition to have Tenant adjudged a bankrupt or a petition for
                reorganization or arrangement under any law relating to
                bankruptcy (unless, in the cast of a petition filed against
                Tenant, the same is dismissed within thirty (30 days); (3) the
                appointment of a trustee or receiver to take possession of
                substantially all of Tenant's assets located at the Premises or
                of Tenant's interest in this Lease, where possession is not
                restored to Tenant within thirty (30) days; or (4) the
                attachment, execution or other judicial seizure of substantially
                all of Tenant's assets located at the Premises or of Tenant's
                interest in this Lease where such seizure is not discharged
                within thirty (30) days.

        (b)     In the event of any such default by Tenant, in addition to any
other remedies available to Landlord at law or in equity, Landlord shall have
the immediate option to terminate this Lease and all rights of Tenant hereunder.
In the event that Landlord shall elect to so terminate this lease then Landlord
may recover from Tenant:

                (i)     the worth at the time of award of any unpaid rent which
                had been earned at the time of such termination; plus

                (ii)    the worth at the time of award of the amount by which
                the unpaid rent which would have been earned after termination
                until the time of award exceeds the amount of such rental loss
                that Tenant proves could have been reasonably avoided; plus

                (iii)   the worth at the time of award of the amount by which
                the unpaid rent for the balance of the term after the time of
                award exceeds the amount of such rental loss that Tenant proves
                could be reasonably avoided; plus

                (iv)    any other amount necessary to compensate Landlord for
                all the detriment proximately caused by Tenant's failure to
                perform his obligations under this Lease or which in the
                ordinary course of things would be likely to result therefrom.

        As used in Subparagraphs 25(b)(i) and (ii) above the "worth at the time
of award" is computed by allowing interest at the maximum rate permitted by law
per annum. As used in Subparagraph 25(b)(iii) above, the "worth at the time of
award" is computed by discounting such amount at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one percent
(1%).

        (c)     In the event of any such default by Tenant, Landlord shall also
have the right. with or without terminating this Lease, to re-enter the Premises
and remove all persons and property from the Premises. Such property may be
removed and stored in a public warehouse or elsewhere at the cost of and for the
account of Tenant for such period of time as may be required by applicable law
after which time Landlord may dispose of such property in accordance with
applicable law. No re-entry or taking possession of the Premises by Landlord
pursuant to this Subparagraph 25(c) shall be construed as an election to
terminate this Lease unless a written notice of such intention be given to
Tenant or unless the termination thereof be decreed by a court of competent
jurisdiction.

        (d)     All rights, options' and remedies of Landlord contained in this
Lease shall be construed and held to be cumulative, and no one of them shall be
exclusive of the other, and Landlord shall have the right to pursue any one or
all of such remedies or any other remedy or relief which may be provided by law,
whether or not stated in this Lease. No waiver of any default of Tenant
hereunder shall be implied from any acceptance by Landlord of any rent or other
payments due hereunder or any omission by Landlord to take any action on account
of such default if such default persists or is repeated, and no express waiver
shall affect defaults other than as specified in said waiver. The consent or
approval of Landlord to or of any act by Tenant requiring Landlord's consent or
approval shall not be deemed to waive or render unnecessary Landlord's consent
or approval to or of any subsequent similar acts by Tenant.

        26.     Assignment and Subletting. Tenant shall not voluntarily assign
or encumber its interest in this Lease or in the Premises, or sublease all or
any part of the Premises, or allow any other person or entity to occupy or use
all or any part of the Premises, without first obtaining Landlord's prior
written consent. Any assignment, encumbrance or sublease without Landlord's
prior written consent shall be voidable, at Landlord's election, and shall
constitute a default. For purposes hereof, in the event Tenant is a partnership,
a withdrawal or change of partners, or change of ownership of partners, owning
more than a fifty percent (50%) interest in the partnership, or if Tenant is a
corporation, any transfer of fifty percent (50%) of its stock, shall constitute
a voluntary assignment and shall be subject to these provisions. No consent to
any assignment. encumbrance, or sublease shall constitute a further waiver of
the provisions of this Paragraph. Tenant shall notify Landlord


                                       13



<PAGE>   43



in writing of Tenant's intent to assign encumber, or sublease this lease, the
name of the proposed assignee or sublessee information concerning the financial
responsibility of the proposed assignee or sublessee and the terms of the
proposed assignment or subletting, and Landlord shall, within thirty (30) days
of receipt of such written notice, and additional information requested by
Landlord concerning the proposed assignee's or sublessee's financial
responsibility, elect one of the following:

        (a)     Consent to such proposed assignment, encumbrance or sublease;

        (b)     Refuse such consent, which refusal shall be on reasonable
                grounds;

        (c)     Elect to terminate this Lease, or in the cast of a partial
                sublease, terminate this Lease as to the portion of the Premises
                proposed to be sublet.

Without limiting Landlord's grounds for disapproval, Landlord's disapproval
shall be deemed reasonable if it is based on Landlord's analysis of (a) the
proposed assignee's or sublessee's credit. character and business or
professional standing, (b) whether the assignee's or sublessee's use and
occupancy of the Premises will be consistent with Subparagraph 1(u) and
Paragraph 8 of this Lease and whether assignee's proposed intensity of use is
consistent with that shown by Tenant, (c) whether the proposed assignee or
sublessee is a then existing or prospective tenant of the Building, as a
condition for granting its consent to any assignment, encumbrance or sublease.
Landlord may require that the rent payable by such assignee or sublessee is at
the then current published rental rates for the Premises or comparable Premises
in the Building, but not less than the then current Annual Basic Rent under this
Lease and may require that the assignee or sublessee remit directly to Landlord
on a monthly basis, all monies due to Tenant by said assignee or sublessee. In
the event that Landlord shall consent to any assignment or sublease under the
provisions of this Paragraph 26, Tenant shall pay Landlord's processing costs
and attorneys' lees incurred in giving such consent. If for any proposed
assignment or sublease Tenant receives rent or other consideration either
initially or over the term of the assignment or sublease, in excess of the rent
called for hereunder or, in case of the sublease of a portion of the Premises,
in excess of such rent fairly allocable to such portion after appropriate
adjustments to assure that all other payments called for hereunder are taken
into account Tenant shall pay to Landlord as additional rent hereunder all of
the excess of each such payment of rent or other consideration received by
Tenant promptly after its receipt. Landlord's waiver or consent to any
assignment or subletting shall not relieve Tenant from any obligation under this
Lease. Occupancy of all or part of the Premises by parent, subsidiary, or
affiliated companies of Tenant shall not be deemed an assignment or subletting.
If Tenant requests Landlord's consent to any assignment of this Lease or any
subletting of all or a portion of the Premises, Landlord shall have the right,
to be exercised by giving written notice to Tenant within thirty (30) days of
receipt by Landlord of the financial responsibility information required by this
Paragraph 26 to terminate this Lease effective as of the date Tenant proposes to
assign this Lease or sublet all or a portion of the Premises. Landlord's right
to terminate this lease as to all or a portion of the Premises on assignment or
subletting shall not terminate as a result of Landlord's consent to the
assignment of this Lease or the subletting of all or a portion of the Premises,
or Landlord's failure to exercise this right with respect to any assignment or
subletting.

        27.     Quiet Enjoyment. Landlord convenants and agrees with Tenant that
upon Tenant paying the rent required under this Lease and paying all other
charges and performing all of the covenants and provisions aforesaid on Tenant's
part to be observed and performed under this Lease, Tenant shall and may
peaceably and quietly have, hold and enjoy the Premises in accordance with this
Lease.

        28.     Subordination. Without the necessity of any additional document
being executed by Tenant for the purpose of effecting a subordination, and at
the election of Landlord or any first mortgagee with a lien on the Building or
any ground lessor with respect to the Building, this least shall be subject and
subordinate at all times to; (a) all ground leases or underlying leases which
may now exist or hereafter be executed affecting the Building or the land upon
which the Building is situated or both, and (b) the lien of any mortgage or deed
of trust which may now exist or hereafter be executed in any amount for which
the Building, land, ground leases or underlying leases, or Landlord's interest
or estate in any of said items is specified as security. Nothwithstanding the
foregoing, Landlord shall have the right to subordinate or cause to be
subordinated any such ground leases or underlying leases or any such liens to
this lease. In the event that any ground lease or underlying lease terminates
for any reason or any mortgage or deed of trust is foreclosed or a conveyance in
lieu of foreclosure is made for any reason, Tenant shall, if requested by the
ground lessor, mortgagee or beneficiary, as applicable, attorn to and become the
Tenant of the successor in interest to Landlord and in such event Tenant's right
to possession of the Premises shall not be disturbed if Tenant is not in default
and so long as Tenant shall pay the rent and all other amounts required to be
Paid to Landlord pursuant to the terms hereof and observe and perform all of the
provisions of this Lease, unless the Lease is otherwise terminated pursuant to
its terms. Tenant covenants and agrees to execute and deliver upon demand by
Landlord and in the form requested by Landlord, any additional documents
evidencing the priority or subordination of this Lease with respect to any such
ground leases or underlying leases or the lien of any such mortgage or deed of
trust. Should Tenant fail to sign and return any such documents within ten (10)
business days of receipt, Tenant shall be in default. and Landlord may, at
Landlord's option, terminate this Lease provided written notice of such
termination is received by Tenant prior to Landlord's receipt of such documents.

        29.     Estoppel Certificate.
                  
        (a)     Within ten (10) days following any written request which
Landlord may make from time to time, Tenant shall execute and deliver to
Landlord a statement, in a form substantially similar to the form of Exhibit 'E"
attached hereto certifying; (i) the Commencement Date of this Lease, (ii) the
fact that this Lease is unmodified and in full force and effect (or, if there
have been modifications hereto, that this Lease is in full force and effect, as
modified, and stating the date and nature of such modifications); (iii) the date
to which the rental and other sums payable under this Lease have been paid; (iv)
the fact that there are no current defaults under this Lease by either Landlord
or Tenant except as specified in Tenant's

                                       14



<PAGE>   44



statement; and (v) such other matters requested by Landlord. Landlord and Tenant
intend that any statement delivered pursuant to this Paragraph 29 may be relied
upon by any mortgagee, beneficiary, purchaser or prospective purchaser of the
Building or any interest therein.

        (b)     Tenant's failure to deliver such statement within such time
shall be conclusive upon Tenant (i) that this Lease is in full force and effect,
without modification except as may be represented by Landlord, (ii) that there
are no uncured defaults in Landlord's performance, and (iii) that not more than
one (1) mouth's rent has been paid in advance, except as provided in Paragraph
36 hereof. Tenant's failure to deliver said statement to Landlord within ten
(10) working days of receipt shall constitute a default under this Lease, and
Landlord may, at Landlord's option, terminate the Lease provided written notice
of such termination is received by Tenant prior to Landlord's receipt of said
statement.

        30.     Building Planning. In the event Landlord requires the Premises
for use in conjunction with another suite or for other reasons connected with
the Building planning program upon notifying Tenant in writing, Landlord shall
have the right to move Tenant to other comparable space in the Building of which
the Premises forms a part, at Landlord's sole cost and expense, including all of
Tenant's moving expenses, telephone installation and stationery reprinting
charges, and the terms and conditions of the original Lease shall remain in full
force and effect save and excepting that a revised Exhibit "A" shall become part
of this Lease and shall reflect the location of the new space and Paragraph I of
this Lease shall be amended to include and state all correct data as to the new
space.

        31.     Rules and Regulations. Tenant shall faithfully observe and
comply with the "Rules and Regulations," a copy of which is attached hereto
and marked Exhibit "F" and all reasonable and nondiscriminatory modifications
thereof and additions thereto from time to time put into effect by Landlord.
Landlord shall not be responsible to Tenant for the violation or nonperformance
by any other tenant or occupant of the Building of any of said Rules and
Regulations.

        32.     Conflict of Laws. This Lease shall be governed by and construed
pursuant to the laws of the State of California.

        33.     Successors and Assigns. Except as otherwise provided in this
Lease, all of the covenants, conditions and provisions of this Lease shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective heirs, personal representative, successors and assigns.

        34.     Surrender of Premises. The voluntary or other surrender of this
Lease by Tenant, or a mutual cancellation thereof, shall not work a merger,
and shall, at the option of Landlord, operate as an assignment to it of any or
all subleases or subtenancies. Upon the expiration or termination of this Lease,
Tenant shall peaceably surrender the Premises and all alterations and additions
thereto broom-clean. in good order, repair and condition, reasonable wear and
tear excepted, and shall comply with the provisions of Subparagraphs 14(g) and
14(h). The delivery of keys to any employee of Landlord or to Landlord's agent
or any employee thereof shall not be sufficient to constitute a termination of
this Lease or a surrender of the Premises.

        35.     Professional Fees. 

        (a)     In the event that Landlord should bring suit for the possession
of the Premises, for the recovery of any sum due under this Lease, or because of
the breach of any provisions of this Lease, or for any other relief against
Tenant hereunder, or should either party bring suit against the other with
respect to matters arising from or growing out of this Lease, then all costs and
expenses, including without limitation, its actual professional fees such as
appraisers', accountants' and attorneys' fees, incurred by the prevailing part
therein shall be paid by the other party, which obligation on the part of the
other party shall be deemed to have accrued on the date of the commencement of
such action and shall be enforceable whether or not the action is prosecuted to
judgment.

        (b)     Should Landlord be named as a defendant in any suit brought
against Tenant in connection with or arising out of Tenant's occupancy
hereunder, Tenant shall pay to Landlord its costs and expenses incurred in such
suit, including without limitation, its actual professional fees such as
appraiser's, accountants' and attorneys' fees.

        36.     Performance by Tenant. All covenants and agreements to be
performed by Tenant under any of the terms of this Lease shall be performed by
Tenant at Tenant's sole cost and expense and without any abatement of rent.
Tenant acknowledges that the late payment by Tenant to Landlord of any sums due
under this Lease will cause Landlord to incur costs not contemplated by this
Lease, the exact amount of such cost being extremely difficult and impractical
to fix. Such costs include, without limitation, processing and accounting
charges, and late charges that may be imposed on Landlord by the terms of any
encumbrance and note secured by any encumbrance covering the Premises or the
Building of which the Premises are a part. Therefore if any monthly installment
of Annual Basic Rent is not received by Landlord by the date when due, or if
Tenant fails to pay any other sum of money due hereunder and such failure
continues for ten (10) days after notice thereof by Landlord, Tenant shall pay
to Landlord, as additional rent, the sum of five percent (5 %) of the overdue
amount as a late charge. Such overdue amount shall also bear interest, as
additional rent, at the maximum rate permissible by law calculated, appropriate,
from the date either (a) the monthly installment of Annual Basic Rent is due, or
(b) of receipt of said notice, until the date of payment to Landlord. Landlord's
acceptance of any late charge or interest shall not constitute a waiver of
Tenant's default with respect to the overdue amount or prevent Landlord from
exercising any of the other rights and remedies available to Landlord under this
Lease or any law now or hereafter in effect. Further, in the event such late
charge is imposed by Landlord for two (2) consecutive months for whatever
reason, Landlord shall have the option to require that, beginning with the first
payment of rent due following the imposition of the second consecutive late
charge, rent shall no longer be Paid in monthly installments but shall be
payable three (3) months in advance.



                                       15

        37.     Mortgagee and Senior Lessor Protection. No act or failure to act
on the part of Landlord which would entitle Tenant under the terms of this
Lease, or by law, to be relieved of Tenant's obligations hereunder or to
terminate this Lease, shall result in a release of such obligations or a
termination of this Lease unless (a) Tenant has given notice by registered or
certified mail to any beneficiary of a dead of trust or mortgage covering the
Premises and to the Lessor under any master or ground lease covering the
Building, the Site or any interest therein whose identity and address shall have
been furnished to Tenant, and (b) Tenant offers such beneficiary, mortgagee or
Lessor a reasonable opportunity to cure the default, including time to obtain
possession of the Premises by power of sale or of judicial foreclosure, if such
should prove necessary to effect a cure.

        38.     Definition of Landlord. The term "Landlord" as used in this
Lease, so far as covenants or obligations on the part of Landlord are concerned,
shall be limited to mean and include only the owner or owners, at the time in
question, of the fee title to, or a lessee's interest in a ground lease of the
Site or master lease of the Building. In the event of any transfer, assignment
or other conveyance or transfer of any such title or interest, Landlord herein
named (and in case of any subsequent transfers or conveyances, the then grantor)
shall be automatically freed and relieved from and after the date of such
transfer, assignment or conveyance of all liability with respect to the
performance of any covenants or obligations on the part of Landlord contained in
this Lease thereafter to be performed and, without further agreement, the
transferee of such title or interest shall be deemed to have agreed to observe
and perform any and all obligations of Landlord hereunder, during its ownership
of the Premises, Landlord may transfer its interest in the Premises without the
consent of Tenant and such transfer or subsequent transfer shall not be deemed a
violation on Landlord's part of any of the terms and conditions of this Lease.

        39.     Waiver. The failure of Landlord to seek redress for violation
of, or to insist upon strict performance of, any term, covenant or condition of
this Lease or the Rules and Regulations attached hereto as Exhibit "F", shall
not be deemed a waiver of such violation or prevent a subsequent act which would
have originally constituted a violation from having all the force and effect of
an original violation, nor shall the failure of Landlord to enforce any of said
Rules and Regulations against any other tenant of the Building be deemed a
waiver of any such Rule or Regulation, nor shall any custom or practice which
may become established between the parties in the administration of the terms
hereof be deemed a waiver of, or in any way affect, the right of Landlord to
insist upon the performance by Tenant in strict accordance with said terms. The
subsequent acceptance of rent hereunder by Landlord shall not be deemed to be a
waiver of any preceding breach by Tenant of any term, covenant or condition of
this Lease, other than the failure of Tenant to pay the particular rent so
accepted, regardless of Landlord's knowledge of such preceding breach at the
time of acceptance of such rent.

        40.     Identification of Tenant. Unless the provisions of Paragraph 55
herein below are applicable to this Lease, then if more thin one person executes
this Lease as Tenant, (a) each of them is jointly and severally liable for the
keeping observing and performing of all of the terms, covenants, conditions,
provisions and agreements of this Lease to be kept, observed and performed by
Tenant, and (b) the term "Tenant" as used in this Lease shall mean and include
each of them jointly and severally and the act of or notice from, or notice or
refund to, or the signature of, any one or more of them, with respect to the
tenancy or this Lease, including, but not limited to, any renewal, extension,
expiration, termination or modification of this Lease, shall be binding upon
each and all of the persons executing this Lease as Tenant with the same force
and effect as if each and all of them had so acted or so given or received such
notice or refund or so signed.

        41.     Parking. The use by Tenant, its employees and invitees, of the
parking facilities of the Building shall be on the terms and conditions set
forth in Exhibit F attached hereto and by this reference incorporated herein and
shall be subject to such other agreement between Landlord and Tenant as may
hereinafter be established.

agreements of the parties hereto with respect to any matter covered or mentioned
in this Lease, and no prior agreement or understanding, oral or written, express
or implied, pertaining to any such matter shall be effective for any purpose. No
provision of this Lease may be amended or added to except by an agreement in
writing signed by the parties hereto or their respective successors in interest.
The parties acknowledge that all prior agreements, representations and
negotiations are deemed superseded by the execution of this Lease to the extent
they are not incorporated herein.

        47.     Separability. Any provision of this Lease which shall prove to
be invalid, void or illegal in no way affects, impairs or invalidates any other
provision hereof, and such other provisions shall remain in full force and
effect.

        48.     Recording. Neither Landlord nor Tenant shall record this Lease
nor a short memorandum thereof without the consent of the other and if such
recording occurs, it shall be at the sole cost and expense of the party
requesting the recording, including any documentary transfer taxes or other
expenses related to such recordation.

        49.     Limitation on Liability. The obligations of Landlord under this
Lease do not constitute personal obligations of the individual partners,
directors, officers or shareholders of Landlord, and Tenant shall not seek
recourse against the individual partners, directors, officers or shareholders of
Landlord or any of their personal assets for satisfaction of any liability in
respect to this Lease. In consideration of the benefits accruing hereunder,
Tenant and all successors and assigns covenant and agree that in the event of
any actual or alleged failure, breach or default hereunder by Landlord, the sole
and exclusive remedy shall be against Landlord's interest in the Building.

        50.     Riders. Clauses, plats and riders, if any, signed by Landlord

        52.     Modification of Lender. If in connection with obtaining
construction, interim or permanent financing for the Building, the lender shall
request reasonable modifications in this Lease as a condition to such financing,
Tenant will not unreasonably withhold, delay or defer its consent thereto,
provided that such modifications do not increase the obligations of Tenant
hereunder or materially adversely affect the leasehold interest hereby created
or Tenant's rights hereunder.

        53.     Accord and Satisfaction. No payment by Tenant or receipt by
Landlord of a lessor amount than the rent payment herein stipulated shall be
deemed to be other than on account of the rent, nor shall any endorsement or
statement on any check or any letter accompanying any check or payment as rent
be deemed an accord and satisfaction and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
rent or pursue any other remedy provided in this Lease. Tenant agrees that each
of the foregoing covenants and agreements shall be applicable to any covenant or
agreement either expressly contained in this lease or imposed by any statute or
at common law.

        54.     Financial Statements. At any time within reason during the term
of this Lease, Tenant shall, upon ten (10) days prior written notice from
Landlord, provide Landlord with a current financial statement and financial
statements of the two (2) years prior to the current financial statement year.
Such statement shall be prepared in accordance with generally accepted
accounting principles and, if such is the normal practice of Tenant, shall be
audited by an independent certified public accountant.

        55.     Tenant as Corporation. If Tenant executes this lease as a
corporation, then Tenant and the persons executing this Lease on behalf of
Tenant represent and warrant that the individuals executing this lease on
Tenant's behalf are duly authorized to execute and deliver this Lease on its
behalf in accordance with a duly adopted resolution of the board of directors of
Tenant, a copy of which is to be delivered to Landlord on execution hereof, and
in accordance with the By-Laws of Tenant and that this lease is binding upon
Tenant in accordance with its terms.

        56.     No Partnership or Joint Venture. Nothing in this Lease shall be
deemed to constitute Landlord and Tenant as partners or joint venturers. It is

this Lease be and remain that of landlord and tenant.

57.     Telecommunications/Intra-Building Network Cable.

        (a)     Subject to the exclusions hereafter set forth, the
intra-building network cable ("INC") shall mean, collectively, all telephone
wiring in the Building that begins at the terminal block closest to where the
telephone company facilities enter the Building. The INC shall exclude the
following wiring: (1) the wiring extending from the central distribution panel
of the Building to the outlet at the Premises to the extent such wiring is used
exclusively to service the Premises and (2) the wiring extending from such
outlet to the various installations in the Premises.

        (b)     Upon discovering or suspecting a defect, deficiency or
malfunctioning in any telecommunication service or services in the Building,
Tenant shall give to Landlord prompt notice of any such known or suspected
defect, deficiency or malfunctioning so as to enable Landlord to remedy the
problem and restore full service or remove the risk of an interruption of or
breakdown in service. Under no circumstances, shall Tenant take or cause to be
taken any remedial action or measures or otherwise resort to "self-help", for
the purpose of restoring such telecommunication service or services; instead,
Tenant shall rely upon Landlord taking all necessary action or measures,
following receipt of notice from Tenant. Tenant further agrees that,
notwithstanding any provision of this Lease to the contrary, it will not do any
of the following: (i) use any electrical or electronic devices or equipment
unless the same complies with Rule 15 of the Federal Communications Commission
Rules or (ii) connect or attach any device with or to the INC without, first,
(A) having given advance notice thereof to Landlord, describing in sufficient
detail the action proposed to be taken by Tenant and (B) having received, prior
to taking such action, Landlord's written approval thereof.

        (c)     Without limiting the generality of Subparagraph 19(a), Tenant
shall indemnify and hold Landlord harmless, and shall, at its sole cost and
expense, defend Landlord from and against any and all claims, liability, loss,
damages, costs and expenses, including reasonable attorneys' fees, arising out
of or in any way connected with (i) any repairs, modifications or additions of
or to the INC made, in violation of the provisions of this Lease, by Tenant, its
agents, employees or business invitees or (ii) any damage to the INC or
interference with the telecommunications services in the Building caused by the
acts or omissions of Tenant, its agents, employees or business invitees;
further, the costs and expenses referred to in the foregoing provisions of this
Subparagraph (c) shall, in addition to the cost of correcting any such repairs,
modifications or additions to or of the INC, any such damage to the INC or any
such interference with telecommunication services, include the cost to the
Landlord of handling and disposing of claims or complaints of other tenants in
the Building whose telecommunications service was interrupted or otherwise
affected by the conduct or actions of Tenant, its agents, employees or business
invitees. The provisions of this Subparagraph 60(c) shall survive the expiration
of the Term of this Lease or earlier termination of this Lease pursuant to its
terms.

IN WITNESS WHEREOF, the parties have executed this Lease the day and year first
above written.

Continued from Page 3, "Rent Escalation":

         ADJUSTED BASIC RENT. Each year during the term of this Lease other than
the Base Year, the Basic Rent or the prevailing Adjusted Basic Rent, as the case
may be, shall be adjusted for the ensuing twelve (12) months by the use of the
Consumer Price Index (All Urban Consumers component) for the San
Francisco-Oakland Area (1982 - 1984 - 100) published by the Bureau of Labor
Statistics of the U. S. Department of Labor. The Basic Rent will be increased by
the percentage increase, if any, between the latest index published just prior
to the commencement of the Lease Term and the comparable latest index published
just prior to January of the following year to arrive at the Adjusted Basic
Rent. Each year thereafter, the Adjusted Basic Rent will be increased by the
percentage increase, if any, between the index published just prior to January
of the subsequent year and the comparable latest index published just prior to
January of the preceding year.

         In case the U.S. Department of Labor shall discontinue the computation
and publication of said Consumer Price Index or the publication thereof should
be delayed so as to prevent its use hereunder at the times required, there shall
be substituted therefor by Landlord such other index or method of ascertaining
changes in the price level as, in the opinion of Landlord, most closely
resembles the Consumer Price Index and method of arriving at the index figure by
said Bureau.

         The commencement of the term of Lease and Tenant's obligation for the
payment of rental under the Lease shall not commence until substantial
completion of construction of the Tenant Improvements. However, if there shall
be a delay in substantial completion of the Tenant Improvements as a result of:

                  obligation in accordance with and by the date specified in the

                  (ii) Tenant's request for materials, finishes or installations
                  other than those readily available; or

                  (iii) Tenant's changes in the Tenant Improvement Plans after
                  their approval by Tenant;

         Then the commencement of the term of the Lease and the rental
commencement date shall be accelerated by the number of days of such delay.

                      STANDARDS FOR UTILITIES AND SERVICES


         The following Standards for utilities and Services are in effect.
Landlord reserves the right to adopt nondiscriminatory modifications and
additions hereto:

         As long as Tenant is not in default under any of the terms, covenants,
conditions, provisions or agreements of this Lease, Landlord shall:

         (a) Provide non-attended automatic elevator facilities Monday through
Friday, except holidays from 8 a.m. to 6 p.m.

         (b) On Monday through Friday, except holidays, from 8 a.m. to 6 p.m.
(and other times for a reasonable additional charge to be fixed by Landlord),
ventilate the Premises and furnish air conditioning or heating on such days and
hours, when in the judgment of Landlord it may be required for the comfortable
occupancy of the Premises. The air conditioning system achieves maximum cooling
when the window coverings are closed. Tenant agrees to cooperate fully at all
times with Landlord, and to abide by all regulations and requirements which
Landlord may prescribe for the proper function and protection of said air
conditioning system. Tenant agrees not to connect any apparatus, device conduit
or pipe to the Building chilled and hot water air conditioning supply lines.
Tenant further agrees that neither Tenant nor its servants, employees, agents,
visitors, licensees or contractors shall at any time enter mechanical
installations or facilities of the Building or adjust, tamper with, touch or
otherwise in any manner affect said installations or facilities. The cost of
maintenance and service calls to adjust and regulate the air conditioning system
shall be charged to tenant if the need for maintenance work results from either
Tenant's adjustment of room thermostats or Tenant's failure to comply with it
obligations under this section, including keeping window coverings closed as
needed. Such work shall be charged at hourly rates equal to then-current
journeymen's wages for air conditioning mechanics.

         (c) Landlord shall furnish to the Premises, during the usual business
hours on business days, electric current as required by the Building standard
office lighting and fractional horsepower office business machines in an amount
not to exceed .025 KWH per square foot per normal business day. Tenant agrees,
should its electrical installation or electrical consumption be in excess of the
aforesaid quantity or extend beyond normal business hours, to reimburse Landlord
monthly for the measured consumption at the average cost per kilowatt hour
charged to the Building during the period. If a separate meter is not installed
at Tenant's cost, such excess cost will be established by an estimate agreed
upon by Landlord and Tenant, and if the parties fail to agree, as established by
an independent licensed engineer. Said estimates to be reviewed and adjusted
quarterly. Tenant agrees not to use any apparatus or device in, or upon, or
about the Premises which may in any way increase the amount of such services
usually furnished or supplied to said Premises, and Tenant further agrees not to
connect any apparatus or device with wires, conduits or pipes, or other means by
which such services are supplied, for the purpose of using additional or unusual
amounts of such services without written consent of Landlord. Should Tenant use
the same to excess, the refusal on the part of Tenant to pay upon demand of
Landlord the amount established by Landlord for such excess charge shall
constitute a breach of the obligation to pay rent under this Lease and shall
entitle Landlord to the rights therein granted for such breach. At a11 times
Tenant's use of electric current shall never exceed the capacity of the feeders
to the Building or the risers or wiring installation.

         (d) Water will be available in public areas for drinking and lavatory
purposes only, but if Tenant requires, uses or consumes water for any purposes
in addition to ordinary drinking and lavatory purposes of which fact Tenant
constitutes Landlord to be the sole judge, Landlord may install a water meter
and thereby measure Tenant's water consumption for all purposes. Tenant shall
pay Landlord for the cost of the meter and the cost of the installation thereof
and throughout the duration of Tenant's occupancy Tenant shall keep said meter
and installation equipment in good working order and repair at Tenant's own cost
and expense, in default of which Landlord may cause such meter and equipment to
be replaced or repaired and collect the cost thereof from Tenant. Tenant agrees
to pay for water consumed, as shown on said meter, as and when bills are
rendered, and on default in making such payment. Landlord may pay such charges
and collect the same from Tenant. Any such costs or expenses incurred, or
payments made by Landlord for any of the reasons or purposes hereinabove stated
shall be deemed to be additional rent payable by Tenant and collectible by
Landlord as such.

         (e) Provide janitor service to the Premises, provided the same are used
exclusively as offices, and are kept reasonably in order by Tenant, and if to be
kept clean by Tenant, no one other than persons approved by Landlord shall be
permitted to enter the Premises for such purposes. If the Promises are not used
exclusively as offices, they shall be kept clean and in order by Tenant, at
Tenant's expense, and to the satisfaction of Landlord, and by persons approved
by Landlord. Tenant shall pay to Landlord the cost of removal of any of Tenant's
refuse and rubbish, to the extent that the same exceeds the refuse and rubbish
usually attendant upon the use of the Premises as offices.

         Landlord reserves the right to stop service of the elevators, plumbing,
ventilation, air conditioning and electric systems, when necessary, by reason of
accident or emergency or for repairs, alterations or improvements, in the
judgement of Landlord desirable or necessary to be made, until said repairs,
alterations or improvements shall have been completed, and shall further have no
responsibility or liability for failure to supply elevator facilities, plumbing,
ventilating, air conditioning or electric service, when prevented from so doing
by strike or accident or by any cause beyond Landlord's reasonable control, or
by laws, rules, orders, ordinances, directions, regulations or requirements of
any federal, state, county or municipal authority or failure of gas, oil or
other suitable fuel supply or inability by exercise of reasonable diligence to
obtain gas, oil or other suitable fuel. It is expressly understood and agreed
that any covenants on Landlord's part to furnish any service pursuant to any of
the terms, covenant, conditions, provisions or agreements of this Lease or to
perform any act or thing for the benefit of Tenant, shall not be deemed breached
if Landlord is unable to furnish or perform the same by virtue of a strike or
labor trouble or any other cause whatsoever beyond Landlord's control.

Building by Landlord after the date of the Lease that are required under any
governmental law or regulation that was not applicable to the Building at the
time it was constructed, or (b) replacement of any building equipment needed to
operate the Building at the same quality levels as prior to the replacement;

         from the Premises or as against Landlord's business of leasing the
         Premises;

         (ii) any assessment, tax, fee, levy or charge in substitution,
         partially or totally, of any assessment, tax, fee, levy or charge
         previously included within the definition of real estate tax, it being
         acknowledged by Tenant and Landlord that Proposition 13 was adopted by
         the voters of the State of California in the June, 1978 Election and
         that assessments, taxes, fees, levies and charges may be imposed by
         governmental agencies for such services as fire protection, street,
         sidewalk and road maintenance, refuse removal and for other
         governmental services formerly provided without charge to property

         be included within the definition of "real property taxes" for the
         purposes of this Lease;

         (iii) any assessment, tax, fee, levy or charge allocable to or measured
         by the area of the Premises or the rent payable hereunder, including,
         without limitation, any gross income tax or excise tax levied by the
         State, City or Federal government, or any political subdivision
         thereof, with respect to the receipt of such rent, or upon or with
         respect to the possession, leasing, operating, management, maintenance,
         alteration, repair, use or occupancy by Tenant of the Premises, or any
         portion thereof;

         (iv) any assessment, tax, fee, levy or charge upon this transaction or

         related to any transportation plan, fund or system instituted within
         the geographic area of which the Building is a part; or

         (vi) reasonable legal and other professional fees, costs and
         disbursements incurred in connection with proceedings to contest,
         determine or reduce real property taxes.

         Notwithstanding any provision to this sub 6(a) expressed or implied to
the contrary, "real property taxes" shall not include Landlord's federal or
state income, franchise, inheritance or estate taxes.





                                        4
<PAGE>   69
By the first day of March of each succeeding calendar year during the term of
this Lease, Landlord shall endeavor to deliver to Tenant a statement ("Estimate
Statement") wherein Landlord shall estimate the Operating Expenses for the
current calendar year, and the amount by which Tenant's Percentage Share of the
Operating Expense on account of the operation or maintenance of the Building is
in excess of the Operating Expenses Allowance. If Tenant's Percentage Share of
the Operating Expense estimated in the Estimate Statement exceeds the Operating
Expenses Allowance then such excess amount shall be divided into twelve (12)
equal monthly installments and Tenant shall pay to Landlord, concurrently with
the regular monthly rent payment next due following the receipt of such
statement, an amount equal to one (1) monthly installment multiplied by the
number of months from January in the calendar year in which said statement is
submitted to the month of such payment, both months inclusive. Subsequent
installments shall be paid concurrently with the regular monthly rent payments
for the balance of the calendar year and shall continue until the next calendar
year's Estimate Statement is rendered. By the first day of June of each
succeeding calendar year during the term of this Lease, Landlord shall endeavor
to deliver to Tenant a statement ("Actual Statement") wherein Landlord shall
state the actual Operating Expenses for the preceding calendar year. If the
Actual Statement reveals a greater increase in Tenant's Percentage Share of
Operating Expenses that was estimated by Landlord in the Estimated Statement
delivered as provided herein, then upon receipt of the Actual Statement from
Landlord, Tenant shall pay a lump sum equal to said total increase over the
Operating Expenses Allowance, less the total of the monthly installments of
increases set forth on the Estimate Statement which were paid in the previous
calendar year. If, in any calendar year, Tenant's Percentage Share of Operating
Expenses is less than the preceding calendar year, then upon receipt of
Landlord's Actual Statement, any overpayment made by Tenant on the monthly
installment basis provided above shall be credited toward the next monthly rent
falling due and the monthly installment of Tenant's Percentage Share of
Operating Expenses to be paid pursuant to the then current Estimate Statement
shall be adjusted to reflect such lower expenses for the most recent calendar
year, or if this Lease has been terminated, such excess shall be credited
against any amount which Tenant owes Landlord pursuant to this Lease and, to the
extent all amounts which Tenant owes Landlord pursuant to this Lease have been
paid, Landlord shall promptly pay such excess to Tenant. Any delay or failure by
Landlord in delivering any estimate or statement pursuant to this Paragraph
shall not constitute a waiver of its right to require an increase in rent nor
shall it relieve Tenant of its obligations pursuant to this Paragraph, except
that Tenant shall not be obligated to make any payments based on such estimate
or statement until ten (10) days after receipt of such estimate or statement.

         (c) Even though the term as expired and Tenant has vacated the
Premises, when the final determination is made of Tenant's Percentage Share of
Operating Expenses for the year in which this Lease terminates, Tenant shall
immediately pay any increase due over the estimated expenses paid and conversely
any overpayment made in the event said expenses decrease shall be immediately
rebated by Landlord to Tenant.

         (d) Notwithstanding anything contained in this Paragraph 6, the rental
payable by Tenant shall in no event be less than the rent specified in Paragraph
5 hereof.

         7. SECURITY DEPOSIT. Tenant has deposited with Landlord the Security
Deposit designated in Subparagraph 1(t). Said deposit shall be held by Landlord
as security for the faithful performance by Tenant of all of the terms,
covenants, and conditions of this Lease to be kept and performed by Tenant
during the term hereof. If Tenant defaults with respect to any provision of this
Lease, including but not limited to the provisions relating to the payment of
rent, Landlord may (but shall not be required to) use, apply or retain all or
any part of this Security Deposit for the payment of any rent or any other sum
in default, or for the payment of any other amount which Landlord may spend or
become obligated to spend by reason of Tenant's default or to compensate
Landlord for any loss or damage which Landlord may suffer by reason of Tenant's
default. If any portio of said deposit is so used or applied, Tenant shall,
within ten (10) days after demand therefor, deposit cash with Landlord in an
amount sufficient to restore the Security Deposit to its original amount and
Tenant's failure to do so shall be a material breach of this Lease. Landlord
shall not be required to keep this Security Deposit separate from its general
funds, and Tenant shall not be entitled to interest on such Security Deposit. If
Tenant shall fully and faithfully perform every provision of this Lease to be
performed by it, the Security Deposit or any balance thereof shall be returned
to Tenant (or, at Landlord's option, to the last assignee of Tenant's interests
hereunder) at the expiration of the Lease term, provided that Landlord may
retain the Security Deposit until such time as any amount due from Tenant in
accordance with Paragraph 5 and 6 hereof has been determined and paid in full.
Should Landlord sell its interest in the Premises during the term hereof and if
Landlord deposits with the purchaser thereof the then unappropriated funds
deposited by Tenant as aforesaid, thereupon Landlord shall be discharged from
any further liability with respect to such Security Deposit.

         8. USE. Tenant shall use the Premises for general office purposes and
purposes incident thereto in compliance with Exhibit H, Hazardous Waste, and
shall not use or permit the Premises to be used for any other purposes without
the prior written consent of Landlord. Tenant shall not use or occupy the
Premises in violation of any recorded covenants, conditions, and restrictions
affecting the Site or of any law or of the Certificate of Occupancy issued for
the Building of which the Premises are a part, and shall upon five (5) days'
written notice from Landlord, discontinue any use of the Premises which is
declared by any governmental authority having jurisdiction to be a violation of
any recorded covenants, conditions and restrictions affecting the Site or of any
law or of said Certificate of Occupancy. Tenant may not offer shared tenant
services,


                                        5
<PAGE>   70
 
such as but not limited to telecommunications, data processing or word
processing, to any unaffiliated tenant in the Building without Landlord's prior
written consent, which consent may be withheld by Landlord at its sole and
absolute discretion. Tenant shall not install any radio or television antenna,
loudspeaker or other device on the roof or exterior walls of the Building.
Tenant shall not interfere with radio or television broadcasting or reception
from or in the Building or elsewhere. Tenant shall comply with any direction of
any governmental authority having jurisdiction which shall, by reason of the
nature of Tenant's use or occupancy of the Premises, impose any duty upon Tenant
or landlord with respect to the Premises or with respect to the use or
occupation thereof. Tenant shall not do or permit to be done anything which will
invalidate or increase the cost of any fire, extended coverage or any other
insurance policy covering the Building and/or property located therein and shall
comply with all rules, orders, regulations and requirements of the Pacific Fire
Rating Bureau of any other organization performing a similar function. Tenant
shall promptly upon demand reimburse Landlord as additional rent for any
additional premium charged for such policy by reason of Tenant's failure to
comply with the provisions of this Paragraph 8. Tenant shall not do or permit
anything to be done in or about the Premises which will in any way obstruct or
interfere with the rights of other tenants or occupants of the Building, or
injure or annoy them, or use or allow the Premises to be used for any improper,
immoral, unlawful or objectionable purpose, nor shall Tenant cause, maintain or
permit any nuisance in, on or about the Premises. Tenant shall not commit or
suffer to be committed any waste in or upon the Premises and shall keep the
Premises in the first class repair and appearance. Tenant shall not place a load
upon the Premises exceeding the average pounds of live load per square foot of
floor area specified for the Building by Landlord's architect, with the
partitions to be considered a part of the live load. Landlord reserves the right
to prescribe the weight and position of all safes, files and heavy equipment
which Tenant desires to place in the Premises so as to distribute properly the
weight thereof. Tenant's business machines and mechanical equipment which cause
vibration or noise that may be transmitted to the Building structure or to any
other space in the building shall be installed, maintained and used by Tenant as
to eliminate such vibration or noise. Tenant shall be responsible for all
structural engineering required to determine structural load. Tenant shall
fasten all files, bookcases and like furnishings to walls in a manner to prevent
tipping over the event of earth movements. Landlord shall not be responsible for
any damage or liability for such events.

         9. PAYMENTS AND NOTICES. Payments will be by check, only, unless Tenant
is in default as per Paragraph 25. All rents and other sums payable by Tenant to
Landlord hereunder shall be paid to Landlord by check, cashier's check, or cash,
at Landlord's option, at the address designated by Landlord in Subparagraph 1(b)
above or at such other places as Landlord may hereafter designate in writing.
Any notice required or permitted to be given hereunder must be in writing and
may be given by personal delivery or by mail, and if given by mail shall be
deemed sufficiently if sent by registered or certified mail addressed to Tenant
at the Building or to Landlord at both of the addresses designated in
Subparagraph 1(b). Either party may by written notice to the other specify a
different address for notice purposes except that Landlord may in any event use
the Premises as Tenant's address for notice purposes. If more than one person or
entity constitutes the "Tenant" under this Lease, service of any notice upon any
one of said persons or entities shall be deemed as service upon all of said
persons or entities.

         10. BROKERS. The parties recognize that the brokers who negotiated this
Lease are the brokers whose names are stated in Subparagraph 1(v), and agree
that Landlord shall be solely responsible for the payment of brokerage
commissions to said brokers, and that Tenant shall have no responsibility
therefor. As part of the consideration for the granting of this Lease, Tenant
represents and warrants to Landlord that to Tenant's knowledge no other broker,
agent or finder negotiated or was instrumental in negotiating or consummating
this Lease and that Tenant knows of no other real estate broker, agent or finder
who is, or might be, entitled to a commission or compensation in connection with
this Lease. Any broker, agent or finder of Tenant whom Tenant has failed to
disclose herein shall be paid by Tenant. Tenant shall hold Landlord harmless
from all damages and indemnify Landlord for all said damages paid or incurred by
Landlord resulting from any claims that may be asserted against Landlord by any
broker, agent or finder undisclosed by Tenant herein.

         11. HOLDING OVER. It Tenant holds over after the expiration or earlier
termination of the term hereof without the express written consent of Landlord,
Tenant shall become a tenant at sufferance only, at a rental rate equal to
one-hundred fifty percent (150%) of the Annual Basic Rent which would be
applicable to the Premises upon the date of such expiration (subject to
adjustment as provided in Paragraph 6 hereof and prorated on a daily basis), and
otherwise subject to the terms, covenants and conditions herein specified, so
far as applicable. Acceptance by Landlord of rent after such expiration or
earlier termination shall not constitute a holdover hereunder or result in a
renewal. The foregoing provisions of this Paragraph 11 are in addition to and do
not affect Landlord's right of re-entry or any rights of Landlord hereunder or
as otherwise provided by law. If Tenant fails to surrender the Premises upon the
expiration of this Lease despite demand to do so by Landlord, Tenant shall
indemnify and hold Landlord harmless from all loss or liability, including
without limitation, any claim made by any succeeding tenant founded on or
resulting from such failure to surrender.

         12.      TAXES ON TENANT'S PROPERTY.

         (a) Tenant shall be liable for and shall pay at least ten (10) days
before delinquency, taxes levied against any personal property or trade fixtures
placed by Tenant in or about the Premises. If any such taxes on Tenant's
personal property or trade fixtures are levied against Landlord or Landlord's
property or if the assessed value of the Premises is increased by inclusion
therein of a value placed upon such personal property or trade fixtures of
Tenant and if Landlord, after written notice to Tenant, pays the taxes based
upon such increased assessments, which Landlord shall have the right to do
regardless of the validity thereof, but only under proper protest if requested
by Tenant, Tenant shall upon demand repay to Landlord the taxes levied against
Landlord, or the proportion of such taxes resulting from such increase in the
assessment; provided that in any such event, at Tenant's sole cost and expense,
Tenant shall have the right, in the name of Landlord and with Landlord's full
cooperation, to bring suit in any court of competent jurisdiction to recover the
amount of any such taxes so paid under protest, any amount so recovered to
belong to Tenant.

         (b) If the Aggregate Improvements in the Premises, whether installed
and/or paid for by Landlord or Tenant and whether or not affixed to the real
property so as to become a part thereof, are assessed for real property taxes
purposes at a


                                        6
<PAGE>   71
valuation higher than the valuation at which Aggregate Improvements conforming
to Landlord's "Building Standard" in other space in the Building are assessed,
then the real property taxes and assessment levied against the Landlord or the
property by reason of such excess assessed valuation shall be deemed to be taxes
levied against personal property of Tenant and shall be governed by the
provisions of Subparagraph 12(a), above. If the records of the County Assessor
are available and sufficiently detailed to serve as a basis for determining
whether said Aggregate Improvements are assessed at a higher valuation than
Landlord's "Building Standard," such records shall be binding on both Landlord
and Tenant. If the records of the County Assessor are not available or
sufficiently detailed to serve as a basis for making said determination, the
actual cost of construction shall be used.

         13. CONDITION OF PREMISES. Tenant acknowledges that neither Landlord
nor any agent of Landlord has made any representation or warranty with respect
to the Premises or the Building or with respect to the suitability of either for
the conduct of Tenant's business. The taking of possession of the Premises by
Tenant shall conclusively establish that the Premises and the Building were at
such time in satisfactory condition, however, partial occupancy and rent
commencement will not interfere with Landlord's obligation to complete Tenant
Improvements. Without limiting the foregoing, Tenant's execution of the Notice
attached hereto as Exhibit "D" shall constitute a specific acknowledgment and
acceptance of the various start-up inconveniences that may be associated with
the use of the Building Common Areas such as certain construction obstacles
including scaffolding, delays in the use of freight elevator service, certain
elevators not being available to Tenant, the passage of work crews using
elevators, uneven air conditioning service, and other typical conditions
incident to recently constructed office buildings. Further, Tenant's execution
of said Notice shall constitute an acknowledgment, in light of the practical
impossibility of ensuring that every floor slab has been installed with
absolutely no deflection, that all wood floor coverings, wood paneling, and
similar interior Aggregate Improvements have been and/or will be designed to
accommodate the actual floor slab deflection unique to each particular area of
the Premises to be so improved.

         14. ALTERATIONS.

         (a) Tenant may, at any time and from time to time during the term of
this Lease, at its sole cost and expense, make alterations, additions,
installations, substitutions, improvements, and decorations (hereinafter
collectively called "Change") in and to the Premises, excluding structural
changes, on the following conditions, and providing such Changes will not result
in a violation of or require a change in the Certificate of Occupancy
application to the Premises:

         (i) The outside appearance, character or use of the Building shall not
         be affected, and no Changes shall weaken or impair the structural
         strength or, in the opinion of Landlord, lessen the value of the
         Building or create the potential for unusual expenses to be incurred
         upon the removal of Changes and the restoration of the Premises upon
         the termination of this Lease.

         (ii) No part of the Building outside of the Premises shall be
         physically affected.

         (iii) The proper functioning of any of the mechanical, electrical,
         sanitary and other service systems or installations of the Building
         ("Service Facilities") shall not be adversely affected and there shall
         be no construction which might interfere with Landlord's free access to
         the Service Facilities or interfere with the moving of Landlord's
         equipment to or from the enclosures containing the Service Facilities.

         (iv) In performing the work involved in making such Changes, Tenant
         shall be bound by and observe all of the conditions and covenants
         contained in this Paragraph.

         (v) All work shall be done at such times and in such manner as Landlord
         from time to time may designate.

         (vi) Tenant shall not be permitted to install and make part of the
         Premises any materials, fixtures or articles which are subject to
         liens, conditional sales contracts or chattel mortgages.

         (vii) At the date upon which the term of this Lease shall end, or the
         date of any earlier termination of this Lease, Tenant shall on
         Landlord's written request restore the Premises to their condition
         prior to the making of any Changes permitted by this Paragraph,
         reasonable wear and tear excepted.

         (b) Before proceeding with any Change (exclusive of changes to items
constituting Tenant's personal property), Tenant shall submit to Landlord plans
and specifications for the work to be done, which shall require Landlord's
written approval. Landlord shall then prepare or cause to be prepared, at
Tenant's expense, mechanical, electrical and plumbing drawings and may confer
with consultants in connection with the preparation of such drawings and may
also submit to such consultant(s) any of the plans prepared by Tenant. If
Landlord or such consultant(s) shall disapprove of any of the Tenant's plans
Tenant shall be advised of the reasons of such disapproval. In any event, Tenant
agrees to pay to Landlord, as additional rent, the cost of such consultation and
review immediately upon receipt of invoices either from Landlord or such
consultant(s). Any Change for which approval has been received shall be
performed strictly in accordance with the approved plans and specifications, and
no amendments or additions to such plans and specifications shall be made
without the prior written consent of Landlord.

         (c) If the proposed Change requires approval by or notice to the lessor
of a superior lease or the holder of a mortgage, no Change shall be proceeded
with until such approval has been received, or such notice has been given, as
the case may be and all applicable conditions and provisions of said superior
lease or mortgage with respect to the proposed Change or alteration have been
met or complied with at Tenant's expense; and Landlord, if it approves the
Change, will request such approval or give such notice, as the case may be.





                                        7
<PAGE>   72
         (d) After Landlord's written approval has been sent to Tenant and the
approval by or notice to the lessor of a superior lease or the holder of a
superior mortgage has been received or given, as the case may be, Tenant shall
enter into an agreement for the performance of the work to be done pursuant to
this Paragraph with Landlord's contractor. In any event, Tenant agrees to pay to
Landlord, at Landlord's option, in advance of construction based upon Landlord's
cost estimates, or as additional rent, the cost of such construction immediately
upon receipt from Landlord of invoices from time to time during the course of
such construction. All costs and expenses incurred in Changes shall be paid by
Tenant within seven (7) days after each billing by Landlord or any such
contractor or contractors. If Landlord approves the construction of specific
interior improvements in the Premises by contractors or mechanics selected by
Tenant and approved by Landlord, then Tenant's contractors shall obtain on
behalf of Tenant and at Tenant's sole cost and expense, (i) all necessary
governmental permits and certificates for the commencement and prosecution of
Tenant's Changes and for final approval thereof upon completion, and (ii) a
completion and lien indemnity bond, or other surety, satisfactory to Landlord,
for the Changes. In the event Tenant shall request any changes in the work to be
performed after the submission of the plans referred to in this Paragraph 14,
such additional changes shall be subject to the same approvals and notices as
the changes initially submitted by Tenant.

         (e) Tenant shall pay to Landlord for Landlord's services in the event
Landlord performs as a general contractor in connection with the work performed
pursuant to this Paragraph 14, a fee equal to seven percent (7%) of the total
cost of the changes, and Landlord's reasonable overhead related thereto.

         (f) All Changes and the performance thereof shall at all times comply
with (i) all laws, rules, orders, ordinances, directions, regulations and
requirements of all governmental authorities, agencies, offices, departments,
bureaus and boards having jurisdiction thereof, (ii) all rules, orders,
directions, regulations and requirements of the Pacific Fire Rating Bureau, or
of any similar insurance body or bodies, and (iii) all rules and regulations of
Landlord, and Tenant shall cause Changes to be performed in compliance therewith
and in good and first class workmanlike manner, using materials and equipment at
least equal in quality and class to the original installations of the Building.
Changes shall be performed in such manner as not to interfere with the occupancy
of any other tenant in the Building nor delay or impose any additional expense
upon Landlord in construction, maintenance or operation of the Building, and
shall be performed by Contractors or mechanics approved by Landlord and
submitted to Tenant pursuant to this Paragraph, who shall coordinate their work
in cooperation with any other work being performed with respect to the Building.
Throughout the performance of Changes, Tenant, at its expense, shall carry, or
cause to be carried, workmen's compensation insurance in statutory limits, and
general liability insurance for any occurrence in or about the Building, of
which Landlord and its managing agent shall be named as parties insured, in such
limits as Landlord may reasonably prescribe, with insurers reasonably
satisfactory to Landlord all in compliance with Subparagraph 21(b).

         (g) Tenant further covenants and agrees that any mechanic's lien filed
against the Premises or against the Building for work claimed to have been done
for, or materials claimed to have been furnished to Tenant, will be discharged
by Tenant, by bond or otherwise, within ten (10) days after the filing thereof,
at the cost and expense of Tenant. All alterations, decorations, additions or
improvements upon the Premises, made by either party, including (without
limiting the generality of the foregoing) all wallcovering, built-in cabinet
work, paneling and the like, shall, unless Landlord elects otherwise, become the
property of Landlord, and shall remain upon, and be surrendered with the
Premises, as a part thereof, at the end of the term hereof, except that Landlord
may by written notice to Tenant, given at least thirty (30) days prior to the
end of the term, require Tenant to remove all partitions, counters, railings and
the like installed by Tenant, and Tenant shall repair any damage to the Premises
arising from such removal or, at Landlord's options, shall pay to the Landlord
all of Landlord's costs of such removal and repair.

         (h) All articles of personal property and all business and trade
fixtures, machinery and equipment, furniture and movable partitions owned by
Tenant or installed by Tenant at its expense in the Premises shall be and remain
the property of Tenant and may be removed by Tenant at any time during the lease
term provided Tenant is not in default hereunder, and provided further that
Tenant shall repair any damage caused by such removal. If Tenant shall fail to
remove all of its effects from said Premises upon termination of this Lease for
any cause whatsoever, Landlord may, at its option, remove the same in any manner
that Landlord shall choose, and store said effects without liability to Tenant
for loss thereof, and Tenant agrees to pay Landlord upon demand any and all
expenses incurred in such removal, including court costs and attorney's fees and
storage charges on such effects for any length of time that the same shall be in
Landlord's possession or Landlord may, at its option, without notice, sell said
effects, or any of the same, at private sale and without legal process, for such
price as Landlord may obtain and apply the proceeds of such sale upon any
amounts due under this Lease from Tenant to Landlord and upon the expense
incident to the removal and sale of said effects.

         (i) Subject to Landlord's agreement to minimize any disturbance of
Tenant's use of the Premises, Landlord reserves the right at any time and from
time to time without the same constituting an actual or constructive eviction
and without incurring any liability to Tenant therefor or otherwise affecting
Tenant's obligations under this Lease, to make such changes, alterations,
additions, improvements, repairs or replacements in or to the Site or the
Building (including the Premises required so to do by any law or regulation) and
the fixtures and equipment thereof, as well as in or to the street entrance,
halls, passages and stairways thereof, to change the name by which the Building
is commonly known, except as controlled by the signage provision, Rider #5, as
Landlord may deem necessary or desirable. Nothing contained in this Paragraph 14
shall be deemed to relieve Tenant of any duty, obligation, liability of Tenant
with respect to making any repair, replacement or improvement or complying with
any law, order or requirement of any government or other authority and nothing
contained in this Paragraph 14, shall be deemed or construed to impose upon
Landlord any obligation, responsibility or liability whatsoever, for the care,
supervision or repair of the Building or any part thereof other than as
otherwise provided in this Lease.

         15. REPAIRS.


         (a) By entry hereunder, Tenant accepts the Premises as being in good
and sanitary order, condition and repair, however, partial occupancy and rent
commencement will not interfere with Landlord's obligation to complete Tenant
improvements. Tenant shall, when and if needed or whenever requested by Landlord
to do so, at Tenant's sole cost and expense, maintain and make all repairs to
the Premises and every part thereof, to keep, maintain and preserve the Premises
in first class condition, excepting ordinary wear and tear. Any such maintenance
and repairs shall be performed by Landlord's contractor, or a Landlord's
approved contractor or contractors. All costs and expenses incurred in such
maintenance and repair shall be paid by Tenant within seven (7) days after
billing by Landlord or such contractor or contractors. Tenant shall upon the
expiration or sooner termination of the term hereof surrender the Premises to
Landlord in the same condition as when received, reasonable wear and tear
excepted. Landlord shall have no obligation to alter, remodel, improve, repair,
decorate or paint the Premises or any part thereof and the parties hereto affirm
that Landlord has made no representations to Tenant respected to the condition
of the Premises or the Building except as specifically herein set forth.

         (b) Anything contained in Subparagraph 15(a) above to the contrary
notwithstanding, Landlord shall repair and maintain the structural portions of
the Building, including the basic plumbing, heating, ventilating, air
conditioning and electrical systems installed or furnished by Landlord, unless
such maintenance and repairs are caused in part or in whole by the act, neglect,
fault of or omission of any duty by Tenant, its agents, servants, employees or
invitees, in which case Tenant shall pay to Landlord as additional rent, the
reasonable cost of such maintenance and repairs. Landlord shall not be liable
for any failure to make any such repairs, or to perform any maintenance unless
such failure shall persist for any unreasonable time after written notice of the
need of such repairs or maintenance is given to Landlord by Tenant. Except as
provided in Paragraph 22, hereof there shall be no abatement of rent and no
liability of Landlord by reason of any injury to or interferences with Tenant's
business arising from the making of any repairs, alterations or improvements in
or to any portion of the Building or the Premises or in or to fixtures,
appurtenances and equipment therein. Tenant waives the right to make repairs at
Landlord's expense under any law, statute or ordinance now or hereafter in
effect. Notwithstanding anything to the contrary contained in Subparagraph (a)
and (b) of this Paragraph 15, Tenant shall maintain and repair at its sole cost
and expense, and with maintenance contractors approved by Landlord, all non-base
building facilities, including lavatory, shower, toilet, washbasin and kitchen
facilities and heating and air conditioning systems, including all plumbing
connected to said facilities or systems installed by Tenant or on behavior of
Tenant or existing in the Premises at the time of delivery of possession of the
Premises to Tenant by Landlord. The provisions of the immediately preceding
sentence shall not apply to the basic heating and air conditioning system
provided by Landlord to all tenants in the Building.

         16. LIENS. Tenant shall not permit any mechanic's, materialmen's or
other liens to be filed against the real property of which the Premises form a
part nor against the Tenant's leasehold interest in the Premises. Landlord shall
have the right at all reasonable times to post and keep posted on the Premises
any notices which it deems necessary for protection from such liens. If any such
liens are filed, Landlord may, without waiving its rights and remedies based on
such breach of Tenant and without releasing Tenant from any of its obligations,
cause such liens ton be released by any means if shall deem proper, including
payments in satisfaction of the claim giving rise to such lien. Tenant shall pay
to Landlord at once, upon notice by Landlord, any sum paid by Landlord to remove
such liens, together with interest at the maximum rate per annum permitted by
law from the date of such payment by Landlord.

         17. ENTRY BY LANDLORD. Subject to Landlord's agreement to minimize any
disturbance of Tenant's use of the Premises by exercise of the following rights,
Landlord reserves and shall at any and all times have the right to enter the
Premises to inspect the same, to supply janitor service and any other service to
be provided by Landlord to Tenant hereunder to submit said Premises to
prospective purchasers or, during the last six (6) months of the term of this
Lease, prospective tenants, to post notices of nonresponsibility, to alter,
improve or repair the Premises or any other portion of the Building, all without
being deemed guilty of any eviction of Tenant and without abatement of rent, and
may, in order to carry out such purposes, erect scaffolding and other necessary
structures where reasonably required by the character of the work to be
performed, provided that the business of Tenant shall be interfered with as
little as is reasonable practicable. Tenant hereby waives any claim for damages
for any injury or inconvenience to or interferences with Tenant's business, any
loss of occupancy or quiet enjoyment of the Premises, and any other loss
occasioned thereby. For each of the aforesaid purposes, Landlord shall at all
times have and retain a key with which to unlock all of the doors in, upon and
about the Premises, excluding Tenant's vaults and safes, and Landlord shall have
the means which Landlord may deem proper to open said doors in an emergency in
order to obtain entry to the Premises, and any entry to the Premises obtained by
Landlord by any of said means or otherwise shall not under any circumstances be
construed or deemed to be forcible or unlawful entry into, or a detainer of, the
Premises, or an eviction of Tenant from the Premises or any portion thereof, and
any damages caused on account thereof shall be paid by Tenant. It is understood
and agreed that no provision of this Lease shall be construed as obligating
Landlord to perform any repairs, alterations or decorations except as otherwise
expressly agreed herein to be performed by Landlord. Landlord shall attempt in
the exercise of its rights under this Paragraph 17 to minimize any disturbance
of Tenant's use and possession of the Premises and to provide as much notice to
Tenant as may be reasonably possible prior to any such exercise of Landlord's
rights under this Paragraph 17.

         18. UTILITIES AND SERVICES. Provided that Tenant is not in default
hereunder, Landlord agrees, during the Lease term, to furnish to the Premises as
part of the Operating Expenses during those hours set forth in the Rules and
Regulations as defined in Paragraph 31 hereof, as may be amended in writing by
Landlord from time to time during the term of this Lease and delivered to
Tenant, reasonable quantities of electric current for normal lighting and
fractional horsepower office machines, water for lavatory and drinking purposes,
heat and air conditioning required in Landlord's judgment for the comfortable
use and occupation of the Premises, janitorial service (including washing of
windows with reasonable frequency as determined by Landlord) and elevator
service by non-attended automatic elevators. Landlord shall not be liable for,
and Tenant shall not be entitled to any abatement or reduction of rent by reason
of Landlord's failure to furnish any of the foregoing when such failure is
caused by accident, breakage, repairs, strikes, lockouts or other labor
disturbances or labor disputes of any character, or for any other causes. If
Tenant requires or utilizes more water or electric power than is considered
reasonable or normal by




                                        9
<PAGE>   74
Landlord, Landlord may at its option require Tenant to pay, as additional rent,
the cost, as fairly determined by Landlord, incurred by such extraordinary
usage. In addition, Landlord may install separate meter(s) for the Premises, at
Tenant's sole expense, and Tenant thereafter shall pay all charges of the
utility providing service. Tenant specifically undertakes to install and
maintain at Tenant's cost such fire protection equipment including, without
limitation, emergency lighting as required by any governmental authority or
insurer, and if so required, Tenant shall appoint one of Tenant's personnel to
coordinate with the fire protection facilities and personnel of Landlord. Any
incandescent light bulbs used in the Premises shall be paid for the Tenant. Upon
Tenant's request, Landlord's personnel shall install incandescent light bulbs or
other Building Nonstandard bulbs in the Premises. Tenant agrees to pay Landlord
upon demand Landlord's cost for all such incandescent light bulbs installed or
other Building nonstandard improvements including but not limited to metallic
trim, wood floor covering, glass panels, windows, partitions, kitchens and
executive washrooms in the Premises. Landlord shall not be responsible in any
manner for said maintenance, cleaning and repair.

         19. INDEMNIFICATION. To the fullest extent permitted by law Tenant
hereby agrees to defend, indemnity and hold Landlord harmless against and from
any and all claims arising from Tenant's use of the Premises or the conduct of
its business or from any activity, work, or thing done, permitted or suffered by
Tenant, its agents, contractors, employees or invitees in or about the Premises
or elsewhere, and hereby agrees to further indemnify and hold harmless Landlord
against and from any and all claims arising from any breach or default in the
performance of any obligation on Tenant's part to be performed under the terms
of this Lease or arising from any act, neglect, fault or omission of Tenant, or
of its agents, employees or invitees, and from and against all costs, attorneys'
fees, expenses and liabilities incurred in or about such claim or any action or
proceeding brought thereon. In case any actin or proceeding is brought against
Landlord by reason of any such claim, Tenant upon notice from Landlord hereby
agrees to defend the same at Tenant's expense by counsel approved in writing by
Landlord. Tenant, as a material part of the consideration to Landlord, hereby
assumes all risk of damage to property or injury to persons in, upon or about
the Premises from any cause whatsoever except that which is caused by the
failure of Landlord to observe any of the terms and conditions of this Lease and
such failure has persisted for an unreasonable period of time after written
notice of such failure, and Tenant hereby waives all its claims in request
thereof against Landlord.

         20. DAMAGE TO TENANT'S PROPERTY. Notwithstanding the provisions of
Paragraph 19 to the contrary, Landlord or its agents shall not be liable for any
damage to property entrusted to employees of the building, nor for loss of or
damage to any property by theft or otherwise, nor for any injury or damage to
persons or property resulting from fire, explosion, falling plaster, steams,
gas, electricity, water or rain which may leak from any part of the Building or
from the pipes, appliances or plumbing works therein or from the roof, street or
sub-surface or from any other place or resulting from dampness or any other
patent or latent cause whatsoever. Landlord or its agents shall not be liable
for interference with the light or other incorporeal hereditaments. Tenant
shall give prompt notice to Landlord in case of fire or accidents in the
Premises or in the Building or of defects therein or in the fixtures or
equipment located therein.

         21. INSURANCE.

         (a) During the term hereof, Tenant, at its sole expense, shall obtain
and keep in force the following insurance:

             (i) All Risk insurance upon property owned by Tenant and located in
             the Building for which Tenant is legally liable. Aggregate
             Improvements (other than "Building Standard Work" as described in
             Subparagraph 1(1) hereof), and alterations, in any amount not less
             than ninety percent (90%) of the full replacement cost thereof. All
             such insurance policies shall name Tenant and Landlord as named
             insured thereunder and, at Landlord's request, shall name
             Landlord's mortgagees (and, if applicable, ground or primary
             lessors) as loss payees thereunder, all as their respective
             interests may appear. Landlord will not be required to carry
             insurance of any kind on any "Building Non-Standard Work", as
             described in Subparagraph 1(m) hereof, on Tenant's furniture or
             furnishings, or on any of Tenant's fixtures, equipment,
             improvements, or appurtenances under this Lease, and Landlord shall
             not be obligated to repair any damage thereto or replace the same.

             (ii) Comprehensive general liability insurance coverage, including
             personal injury, bodily injury, broad form property damage,
             operations hazard, owner's protective coverage, contractual
             liability, and products and completed operations liability, in
             limits not less than $2,000,000 inclusive. All such insurance
             policies shall name Tenant as named insured thereunder and shall
             name Landlord and Landlord's mortgagees (and, if applicable, ground
             or primary lessors) as additional insured thereunder, all as their
             respective interests may appear.

             (iii) Worker's Compensation and Employer's Liability insurance,
             with a waiver of subrogation endorsement, in form and amount
             satisfactory to Landlord.

             (v) Liquor liability insurance coverage in limits of not less than
             Five Hundred Thousand Dollars ($500,000) at any time during the
             term or on any occurrence hereof any alcoholic beverages of any
             nature are served on the Premises.

             (vi) Any other form or forms of insurance as Tenant, Landlord, or
             Landlord's mortgagees or ground or primary lessors may reasonably
             require from time to time in form, in amounts, and for insurance
             risks against which a prudent tenant of a comparable size and in a
             comparable business would protect itself.




                                       10
<PAGE>   75
         (b) All policies shall be issued by insurers that are acceptable to
Landlord and in form satisfactory from time to time to Landlord. Tenant will
deliver certificates of insurance to Landlord as soon as practicable after the
placing of the required insurance, but not later than ten (10) days prior to the
date Tenant takes possession of all or any part of the Premises. All policies
shall contain an undertaking by the insurers to notify Landlord and Landlord's
mortgagees (and, if applicable, ground or primary lessors) in writing, not less
than thirty (30) days before any material change, reduction in coverage,
cancellation, or other termination thereof. Ten (10) days prior to the
expiration of any insurance policy, Tenant will provide Landlord with a
Certificate of Insurance extending the term of the original policy or a
certified copy of a new policy extending the required coverage.

         (c) During the Term, Landlord shall insure the Building and the
Building Standard Work (excluding any property which Tenant is obligated to
insure under Subparagraph 21(a) hereof) against damage with All Risk insurance
and public liability insurance, all in such amounts and with such deductions as
Landlord considers appropriate, Landlord may, but shall not be obligated to,
obtain and carry any other form or forms of insurance as it or Landlord's
mortgagees may determine advisable. Notwithstanding any contribution by Tenant
to the cost of insurance premiums, as provided herein, Tenant acknowledges that
it has no right to receive any proceeds from any insurance policies carried by
Landlord.

         (d) Tenant will not keep, use, sell, or offer for sale in, or upon, the
Premises any article which may be prohibited by any insurance policy
periodically in force covering the Building and the Building Standard Work.
Tenant shall promptly comply with all reasonable requirements of the insurance
authority or any present or future insurer relating to the Premises.

         (e) If any Landlord's insurance policies shall be cancelled or
cancellation shall be threatened or the coverage thereunder reduced or
threatened to be reduced in any way because of the use of the Premises or any
part thereof by Tenant or any assignee or sub-tenant of Tenant or by anyone
Tenant permits on the Premises and, if Tenant fails to remedy the condition
giving rise to such cancellation, threatened cancellation, reduction of
coverage, threatened reduction of coverage, increase in premiums, or threatened
increase in premiums, within 48 hours after notice thereof, Landlord may, at its
option, either terminate this Lease or enter upon the Premises and attempt to
remedy such condition, and Tenant shall promptly pay the cost thereof to
Landlord as additional rent. Landlord shall not be liable for any damage or
injury caused to any property of Tenant or of others located on the Premises
resulting from such entry. If Landlord is unable, or elects not, to remedy such
condition, then Landlord shall have all of the remedies provided for in this
Lease in the event of a default by Tenant. Notwithstanding the foregoing
provisions of this Subparagraph 21(e), if Tenant fails to remedy as aforesaid,
Tenant shall be in default of its obligations hereunder and Landlord shall have
no obligations to remedy such default.

         (f) All policies covering real or personal property which either party
obtains affecting the Premises shall include a clause or endorsement denying the
insurer any rights of subrogation against the other party to the extent rights
have been waived by the insured before the occurrence of injury or loss, if same
are obtainable without unreasonable cost. Landlord and Tenant waive any rights
of recovery against the other for injury or loss due to hazards covered by
policies of insurance containing such a waiver of subrogation clause or
endorsement, to the extent of the injury or loss covered thereby.

         22. DAMAGE OR DESTRUCTION.

         (a) In the event the Building and/or the Building Standard Work or any
insured alterations are damaged by fire or other perils covered by Landlord's
extended coverage insurance to an extent not exceeding twenty-five percent (25%)
of the full insurable value thereof and if the damage thereto is such that the
Building and/or the Building Standard Work and any insured alterations may be
repaired, reconstructed or restored within a period of ninety (90) days from the
date of the happening of such casualty and Landlord will receive insurance
proceeds sufficient to cover the cost of such repairs, Landlord shall commence
and proceed diligently with the work of repair, reconstruction and restoration
and the Lease shall continue in full force and effect. If such work or repair,
reconstruction and restoration is such as to require a period longer than ninety
(90) days or exceeds twenty-five percent (25%) of the full insurable value
thereof, or if said insurance proceeds will not be sufficient to cover the cost
of such repairs, Landlord either may elect to so repair, reconstruct or restore
the Building and/or Building Standard Work and any insured alterations and the
Lease shall continue in full force and effect or Landlord may elect not to
repair, reconstruct or restore the Building and/or Building Standard Work and
any insured alterations and the Lease shall in such event terminate. Under any
of the conditions of this Subparagraph 22(a), Landlord shall give written notice
to Tenant of its intention within thirty (30) days from the date of such event
of damage or destruction. In the event Landlord elects not to restore said
Building and/or Building Standard Work and any insured alterations, this Lease
shall be deemed to have terminated as of the date of such partial destructions.

         (b) Upon any termination of this Lease under any of the provisions of
this Paragraph 22, the parties shall be released thereby without further
obligation to the other from the date possession of the Premises is surrendered
to Landlord except for items which have therefore accrued and are then unpaid.

         (c) In the event of repair, reconstructions and restoration by Landlord
as herein provided, the rent provided to be paid under the Lease shall be abated
proportionately with the degree to which Tenant's use of the Premises is
impaired during the





                                       11
<PAGE>   76
period of such repair, reconstruction or restoration. Tenant shall not be
entitled any compensation or damages for loss in the use of the whole or any
part of the Premises and/or any inconvenience, annoyance or loss of business
occasioned by such damage, repair, reconstruction or restoration.

         (d) Tenant shall not be released from any of its obligations under this
Lease except to the extent and upon the conditions expressly stated in this
Paragraph 22. Notwithstanding anything to the contrary contained in this
Paragraph 22, should Landlord be delayed or prevented from repairing or
restoring the damaged Premises within one (1) year after the occurrence of such
damage or destruction by reason of acts of God, war, Governmental restrictions,
inability to procure the necessary labor or materials, or other cause beyond the
control of Landlord, Landlord shall be relieved of its obligation to make such
repairs or restoration and Tenant shall be released from its obligations under
this Lease as of the end of said year.

         (e) In the event that damage is due to any cause other than fire or
other peril covered by extended coverage insurance, Landlord may elect to
terminate this Lease.

         (f) It is hereby understood that if Landlord is obligated to or elects
to repair or restore as herein provided, Landlord shall be obligated to make
repairs or restoration only of those portions of the Building and the Premises
which were originally provided at Landlord's expense or which were insured by
either party and the proceeds of such insurance have been received by Landlord,
and the repair and restoration of items not provided at Landlord's expense shall
be the obligation of Tenant.

         (g) Notwithstanding anything to the contrary contained in this
Paragraph 22, Landlord shall not have any obligations whatsoever to repair,
reconstruct or restore the Premises when the damage resulting from any casualty
covered under this Paragraph 22 occurs during the last twelve (12) months of the
term of this Lease or any extension hereof.

         (h) The provisions of California Civil Code 1932, Subsection 2, and
1933, Subsection 4, are hereby waived by Tenant.

         23. EMINENT DOMAIN.

         (a) In case the whole of the Premises, or such part thereof as shall
substantially interfere with Tenant's use and occupancy thereof, shall be taken
for any public or quasi-public purpose by any lawful power or authority by
exercise of the right of appropriation, condemnation or eminent domain, or sold
to prevent such taking, either party shall have the right to terminate this
Lease effective as of the date possession is required to be surrendered to said
authority. Tenant shall not assert any claim against Landlord or the taking
authority for any compensation because of such taking, and Landlord shall be
entitled to receive the entire amount of any award without deduction for any
estate or interest of Tenant. In the event the amount of property or the type of
estate taken shall not substantially interfere with the conduct of Tenant's
business, Landlord shall be entitled to the entire amount of the award without
deduction for any estate or interest of Tenant, and Landlord at his option may
terminate this Lease. If Landlord does not so elect, Landlord shall promptly
proceed to restore the Premises to substantially their same condition prior to
such partial taking, and a proportionate allowance shall be made to Tenant for
the rent corresponding to the time during which, and to the part of the Premises
of which, Tenant shall be so deprived on account of such taking and restoration.
Nothing contained in this Paragraph shall be deemed to give Landlord any
interest in any aware separately made to Tenant for the taking of personal
property and trade fixtures belonging to Tenant or for moving costs incurred by
Tenant in relocating Tenant's business.

         (b) In the event of taking of the Premises or any part thereof for
temporary use, (i) this Lease shall be and remain unaffected thereby and rent
shall not abate, and (ii) Tenant shall be entitled to receive for itself such
portion or portions of any award made for such use with respect to the period of
the taking which is within the term, provided that if such taking shall remain
in force at the expiration or earlier terminations of this Lease. Tenant shall
then pay to Landlord a sum equal to the reasonable cost of performing Tenant's
obligations under Paragraph 15 with respect to surrender of the Premises and
upon such payment shall be excused from such obligations. For the purpose of
this Subparagraph 23(b), a temporary taking shall be defined as a taking for a
period of 270 days or less.

         24. BANKRUPTCY. If Tenant shall file a petition in bankruptcy under any
Chapter of federal bankruptcy law as then in effect, or if Tenant be adjudicated
a bankrupt in involuntary bankruptcy proceedings and such adjudications shall
not have been vacated within thirty (30) days from the date thereof, or if a
receiver or trustee be appointed of Tenant's property and the order appointing
such receiver or trustee not be set aside or vacated within thirty (30) days
after the entry thereof, or if Tenant shall assign Tenant's estate or effects
for the benefit or creditors, or if this Lease shall otherwise by operation of
law pass to any person or persons other than Tenant, then and in any such event
Landlord may, if Landlord so elects, with or without notice of such election and
with or without entry or action by Landlord, forthwith terminate this Lease.
Notwithstanding any other provisions of this Lease, Landlord, in addition to any
and all rights and remedies allowed by law or equity, shall upon such
termination be entitled to recover damages in the amount provided in
Subparagraph 25(b) below and neither Tenant nor any person claiming through or
under Tenant or by virtue of any statute or order of any court shall be entitled
to possession of the Premises but shall forthwith quit and surrender the
Premises to Landlord. Nothing herein contained shall limit or prejudice the
right of Landlord to prove and obtain as damages by reason of any such
termination an amount equal to the maximum allowed by any statute or rule of law
in effect at the time when, governing the proceedings in which, such damages are
proved, whether or not such amount be greater, equal to, or less than the amount
of damages recoverable under the provisions of this Paragraph 24.

         25.      DEFAULTS AND REMEDIES.


         (a)      The occurrence of any one or more of the following events
shall constitute a default hereunder by Tenant:





                                       12
<PAGE>   77
             (i) The vacation or abandonment of the Premises by Tenant.
             Abandonment is herein defined to included, but is not limited, to,
             any absence by Tenant from the Premises for five (5) days or longer
             while in default of any provision of this Lease.

             (ii) The failure by Tenant to make any payment of rent or
             additional rent or any other payment required to be made by Tenant
             hereunder, as and when due.

             (iii) The failure by Tenant to observe or perform any of the
             express or implied covenants or provisions of this Lease to be
             observed or performed by Tenant, other than as specified in
             Subparagraph 25(a)(i) or (ii) above, where such failure shall
             continue for a period of ten (10) days after written notice thereof
             from Landlord to Tenant; provided, however, that any such notice
             shall be in lieu of, and not in addition to, any notice required
             under California Code of Civil Procedure 1161; provided, further,
             that if the nature of Tenant's default is such that more than ten
             (10) days are reasonably required for its cure, then Tenant shall
             not be deemed to be in default if Tenant shall commence such cure
             within said ten-day period and, thereafter diligently prosecute
             such cure to completion, which completion shall occur not later
             than sixty (60) days from the date of such notice from Landlord.

             (iv) (1) The making by Tenant of any general assignment for the
             benefit of creditors; (2) the filing by or against Tenant of a
             petition to have Tenant adjudged a bankrupt or a petition for
             reorganization or arrangement under any law relating to bankruptcy
             (unless, in the case of a petition filed against Tenant, the same
             is dismissed within thirty (30) days; (3) the appointment of a
             trustee or receiver to take possession of substantially all of
             Tenant's assets located at the Premises or of Tenant's interest in
             this Lease, where possession is not restored to Tenant within
             thirty (30) days; or (4) the attachment, execution or other
             judicial seizure of substantially all of Tenant's assets located at
             the Premises or of Tenant's interest in this Lease where such
             seizure is not discharged within thirty (30) days.


         (b) In the event of any such default by Tenant, in addition to any
other remedies available to Landlord at law or in equity, Landlord shall have
the immediate option to terminate this Lease and all rights of Tenant hereunder.
In the event that Landlord shall elect to so terminate this Lease then Landlord
may recover from Tenant:

             (i) the worth at the time of award of any unpaid rent which had
             been earned at the time of such termination; plus

             (ii) the worth at the time of award of the amount by which the
             unpaid rent which would have been earned after termination until
             the time of award exceeds the amount of such rental loss that
             Tenant proves could have been reasonably avoided; plus

             (iii) the worth at the time of award of the amount by which the
             unpaid rent for the balance of the term after the time of award
             exceeds the amount of such rental loss that Tenant proves could be
             reasonably avoided; plus

             (iv) any other amount necessary to compensate Landlord for all the
             detriment proximately caused by Tenant's failure to perform his
             obligations under this Lease or which in the ordinary course of
             things would be likely a result therefrom.

         As used in Subparagraph 25(b)(i) and (ii) above, the "worth at the time
of award" is computed by allowing interest at the maximum rate permitted by law
per annum. As used in Subparagraph 25(b)(iii) above, the "worth at the time of
award" is computed by discounting such amount at the discount rate of the
Federal Reserve Bank of Service Facilities at the time of award plus one percent
(1%).

         (c) In the event of any such default by Tenant, Landlord shall also
have the right, with or without terminating this Lease, to re-enter the Premises
and remove all persons and property from the Premises. Such property may be
removed and stored in a public warehouse or elsewhere at the cost of and for the
account of Tenant for such period of time as may be required by applicable law
after which Landlord may dispose of such property in accordance with applicable
law. No re-entry or taking possession of the Premises by Landlord pursuant to
this Subparagraph 25(c) shall be construed as an election to terminate this
Lease unless written notice of such intention be given to Tenant or unless the
termination thereof be decreed by a court of competent jurisdiction.

         (d) All rights, options and remedies of Landlord contained in this
Lease shall be construed and held to be cumulative and no one of them shall be
exclusive of the other, and Landlord shall have the right to pursue any one or
all of such remedies or any other remedy or relief which may be provided by law,
whether or not stated in this Lease. No waiver of any default of Tenant
hereunder shall be implied from any acceptance by Landlord of any rent or other
payments due hereunder or any omission by Landlord to take any action on account
of such default if such default persists or is repeated, and no express waiver
shall affect defaults other than as specified in said waiver. The consent or
approval or Landlord to or of any act by Tenant requiring Landlord's consent or
approval shall be deemed to waive or render unnecessary Landlord's consent or
approval to or of any subsequent similar acts by Tenant.

         26. ASSIGNMENT AND SUBLETTING. Tenant shall not voluntarily assign or
encumber its interest in this Lease or in the Premises, or sublease all or any
part of the Premises, or allow any other person or entity to occupy or use all
or any part of the Premises, without first obtaining Landlord's prior written
consent. Any assignment, encumbrance or sublease without Landlord's prior
written consent shall be voidable, at Landlord's election, and shall constitute
a default. For purposes hereof, in the event Tenant is a partnership, a
withdrawal or change of partners, or change of ownership of partners, owning
more than a fifty percent (50%) interest in the partnership, or if Tenant is a
corporation, any transfer of fifty percent (50%) of its stock, shall constitute
a voluntary assignment and shall be subject to these provisions. No consent to
any assignment encumbrance, or sublease shall constitute a further waiver of the
provisions of this Paragraph. Tenant shall notify Landlord





                                       13
<PAGE>   78
in writing of Tenant's intent to assign encumber, or sublease this lease, the
name of the proposed assignee or sublessee, information concerning the financial
responsibility of the proposed assignee or sublessee and the terms of the
proposed assignment or subletting, and Landlord shall, within thirty (30) days
of receipt of such written notice, and additional information requested by
Landlord concerning the proposed assignee's or sublessee's financial
responsibility, elect one of the following:

         (a) Consent to such proposed assignment, encumbrance or sublease;

         (b) Refuse such consent, which refusal shall be on reasonable grounds;

         (c) Elect to terminate this Lease, or in the case of a partial
             sublease, terminate this Lease as to the portion of the Premises
             proposed to be sublet.

         Without limiting Landlord's grounds for disapproval, Landlord's
disapproval shall be deemed reasonable if it is based on Landlord's analysis of
(a) the proposed assignee's or sublessee's credit, character and business or
professional standing, (b) whether the assignee's or sublessee's use and
occupancy of the Premises will be consistent with Subparagraph 1(u) and
Paragraph 8 of this Lease and whether assignee's proposed intensity of use is
consistent with that shown by Tenant, (c) whether the proposed assignee or
sublessee is a then existing or prospective tenant of the Building, as a
condition for granting its consent to any assignment, encumbrance or sublease.
Landlord may require that the rent payable by such assignee or sublessee is at
the then current published rental rates for the Premises or comparable premises
in the Building, but not less than the then current Annual Basic Rent under this
Lease and may require that the assignee or sublessee remit directly to Landlord
on a monthly basis, all monies due to Tenant by said assignee or sublessee. In
the event that Landlord shall consent to any assignment or sublease under the
provisions of this Paragraph 26, Tenant shall pay Landlord's processing costs
and attorneys' fees incurred in giving such consent. If for any proposed
assignment or sublease Tenant receives rent or other consideration, either
initially or over the term of the assignment or sublease, in excess of the rent
called for hereunder, or, in case of the sublease of a portion of the Premises,
in excess of such rent fairly allocable to such portion, after appropriate
adjustments to assure that all other payments called for hereunder are taken
into account, Tenant shall pay to Landlord as additional rent hereunder all of
the excess of each such payment of rent or other consideration received by
Tenant promptly after its receipt. Landlord's waiver or consent to any
assignment or subletting shall not relieve Tenant from any obligation under this
Lease. Occupancy of all or part of the Premises by parent, subsidiary, or
affiliated companies of Tenant shall not be deemed an assignment or subletting.
If Tenant requests Landlord's consent to any assignment of this Lease or any
subletting of all or a portion of the Premises, Landlord shall have the right,
to be exercised by giving written notice to Tenant within thirty (30) days of
receipt by Landlord of the financial responsibility information required by this
Paragraph 26 to terminate this Lease effective as of the date Tenant proposes to
assign this Lease or sublet all or a portion of the Premises. Landlord's right
to terminate this lease as to all or a portion of the Premises on assignment or
subletting shall not terminated as a result of Landlord's consent to the
assignment of this Lease or the subletting of all or a portion of the Premises,
or Landlord's failure to exercise this right with respect to any assignment or
subletting.

         27. QUIET ENJOYMENT. Landlord covenants and agrees with Tenant that
upon Tenant paying the rent required under this Lease and paying all other
charges and performing all of the covenants and provisions aforesaid on Tenant's
part to be observed and performed under this Lease, Tenant shall and may
peaceably and quietly have, hold and enjoy the Premises in accordance with this
Lease.

         28. SUBORDINATION. Without the necessity of any additional document
being executed by Tenant for the purpose of effecting a subordination, and at
the election of Landlord or any first mortgagee with a lien on the Building or
any ground lessor with respect to the Building, this lease shall be subject and
subordinate at all times to: (a) all ground leases or underlying leases which
may now exist or hereafter be executed affecting the Building or the land upon
which the Building is situated or both, and (b) the lien of any mortgage or deed
of trust which may now exist or hereafter be executed in any amount for which
the Building, land, ground leases or underlying leases, or Landlord's interest
or estate in any of said items is specified as security. Notwithstanding the
foregoing, Landlord shall have the right to subordinate or cause to be
subordinated any such ground leases or underlying lease or any such liens to
this lease. In the event that any ground lease or underlying lease terminates
for any reason or any mortgage or deed of trust is foreclosed or a conveyance in
lieu of foreclosure is made for any reason, Tenant shall, if requested by the
ground lessor, mortgagee or beneficiary, as applicable, attorn to and become the
Tenant of the successor in interest to Landlord and in such event Tenant's right
to possession of the Premises shall not be disturbed if Tenant is not in default
and so long as Tenant shall pay the rent and all other amounts required to be
paid to Landlord pursuant to the terms hereof and observe and perform all of the
provisions of this Lease, unless the Lease is otherwise terminated pursuant to
its terms. Tenant covenants and agrees to execute and deliver, upon demand by
Landlord and in the form requested by Landlord, any additional documents
evidencing the priority or subordination of this Lease with respect to any such
ground leases or underlying leases or the lien of any such mortgage or deed of
trust. Should Tenant fail to sign and return any such documents within ten (10)
business days of receipt, Tenant shall be in default, and Landlord may at
Landlord's option, terminate this Lease provided written notice of such
termination is received by Tenant prior to Landlord.

         29. ESTOPPEL CERTIFICATE.

         (a) Within ten (10) days following any written request which Landlord
may make from time to time, Tenant shall execute and deliver to Landlord a
statement, in a form substantially similar to the form of Exhibit "E" attached
hereby, certifying: (i) the Commencement Date of this Lease; (ii) the fact that
this Lease is unmodified and in full force and effect for, if there have been
modifications hereto, that the Lease is in full force and effect, as modified,
and stating the date and nature of such modifications); (iii) the date to which
the rental and other sums payable under this Lease have been paid; (iv) the fact
that there are no current defaults under this Lease by either Landlord or Tenant
except as specified in Tenant's





                                       14
<PAGE>   79
statement; and (v) such other matters requested by Landlord. Landlord and Tenant
intend that any statement delivered pursuant to this Paragraph 29 may be relied
upon by any mortgagee, beneficiary, purchaser or prospective purchaser of the
Building or any interest therein.

         (b) Tenant's failure to deliver such statement within such time shall
be conclusive upon Tenant (i) that this Lease is in full force and effect,
without modification except as may be represented by Landlord, (ii) that there
are no uncured defaults in Landlord's performance, and (iii) that not more than
one (1) month's rent has been paid in advance, except as provided in Paragraph
36 hereof. Tenant's failure to deliver said statement to Landlord within ten
(10) working days of receipt shall constitute a default under this Lease, and
Landlord may, at Landlord's option, terminate the Lease, provided written notice
of such termination is received by Tenant prior to Landlord's receipt of said
statement.

         30. BUILDING PLANNING. In the event Landlord requires the Premises for
use in conjunction with another suite or for other reasons connected with the
Building planning program, upon notifying Tenant in writing, Landlord shall have
the right to move Tenant to other comparable space in the Building of which the
Premises forms a part, at Landlord's sole cost and expense, including all of
Tenant's moving expenses, telephone installation and stationary reprinting
charges, and the terms and conditions of the original Lease shall remain in full
force and effect, safe and excepting that a revised Exhibit "A" shall become
part of this Lease and shall reflect the location of the new space and Paragraph
1 of this Lease shall be amended to include and state all correct data as to the
new space.

         31. RULES AND REGULATIONS. Tenant shall faithfully observe and comply
with the "Rules and Regulations," ??? of which is attached hereto and marked
Exhibit "F", and all reasonable and nondiscriminatory modifications thereof and
additions thereto from time to time put into effect by Landlord. Landlord shall
not be responsible to Tenant for the violation or nonperformance by any other
tenant or occupant of the Building of any of said Rules and Regulations.

         32. CONFLICT OF LAWS. This Lease shall be governed by and construed
pursuant to the laws of the State of California.

         33. SUCCESSORS AND ASSIGNS. Except as otherwise provided in this Lease,
all of the covenants, conditions and provisions of this Lease shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
heirs, personal representative, successors and assigns.

         34. SURRENDER OF PREMISES. The voluntary or other surrender of this
Lease by Tenant, or a mutual cancellation thereof, shall not work a merger, and
shall, at the option of Landlord, operate as an assignment to it of any or all
subleases or subtenancies. Upon the expiration or termination of this Lease,
Tenant shall peaceably surrender the Premises and all alterations and additions
thereto broom-clean, in good order, repair and condition, reasonable wear and
tear excepted, and shall comply with the provisions of Subparagraph 14(g) and
14(h). The delivery of keys to any employee of Landlord or to Landlord's agent
or any employee thereof shall not be sufficient to constitute a termination of
this Lease or a surrender of the Premises.

         35.      PROFESSIONAL FEES.

         (a) In the event that Landlord should bring suit for the possession of
the Premises, for the recovery of any sum due under this Lease, or because of
the breach of any provisions of this Lease, or for any other relief against
Tenant hereunder, or should either party bring suit against the other with
respect to matters arising from or growing out of this Lease, then all costs and
expenses, including without limitation, its actual professional fees such as
appraisers', accountants' and attorneys' fees, incurred by the prevailing part
therein shall be paid by the other party, which obligation on the part of the
other party shall be deemed to have accrued on the date of the commencement of
such action and shall be enforceable whether or not the action is prosecuted to
judgment.

         (b) Should Landlord be named as a defendant in any suit brought against
Tenant in connection with or arising out of Tenant's occupancy hereunder, Tenant
shall pay to Landlord its costs and expenses incurred in such suit, including
without limitation its actual professional fees such as appraiser's,
accountants' and attorneys' fees.

         36. PERFORMANCE BY TENANT. All covenants and agreements to be performed
by Tenant under any of the terms of this lease shall be performed by Tenant at
Tenant's sole cost and expense and without any abatement of rent. Tenant
acknowledges that the late payment by Tenant to Landlord of any sums due under
this Lease will cause Landlord to incur costs not contemplated by this Lease,
the exact amount of such cost being extremely difficult and impractical to fix.
Such costs include, without limitation, processing and accounting charges, and
late charges that may be imposed on Landlord by the terms of any encumbrance and
note secured by any encumbrance covering the Premises or the Building of which
the Premises are a part. Therefore if any monthly installment of Annual Basic
Rent is not received by Landlord by the date when due, or if Tenant fails to pay
any other sum of money due hereunder and such failure continues for ten (10)
days after notice thereof by Landlord, Tenant shall pay to Landlord, as
additional rent, the sum of five percent (5%) of the overdue amount as a late
charge. Such overdue amount shall also bear interest, as additional rent, at the
maximum rate permissible by law calculated, as appropriate, from the date either
(a) the monthly installment of Annual Basic Rent is due, or (b) of receipt of
said notice, until the date of payment to Landlord. Landlord's acceptance of any
late charge or interest shall not constitute a waiver of Tenant's default with
respect to the overdue amount or prevent Landlord from exercising any of the
other rights and remedies available to Landlord under this Lease or any law now
or hereafter in effect. Further, in the event such late charge is imposed by
Landlord for two (2) consecutive months for whatever reason, Landlord shall have
the option to require that, beginning with the first payment of rent due
following the imposition of the second consecutive late charge, rent shall no
longer be paid in monthly installments but shall be payable three (3) months in
advance.

         37. MORTGAGEE AND SENIOR LESSOR PROTECTION. No act or failure to act on
the part of Landlord which would entitle Tenant under the terms of this Lease,
or by law, to be relieved of Tenant's obligations hereunder or to terminate this
Lease, shall result in a release of such obligations or a termination of this
Lease unless (a) Tenant has given notice by registered or certified mail to any
beneficiary of a deed of trust or mortgage covering the Premises and to the
lessor under any master or ground lease covering the Building, the Site or any
interest therein whose identity and address shall have been furnished to Tenant,
and (b) Tenant offers such beneficiary, mortgagee or Lessor a reasonable
opportunity to cure the default, including time to obtain possession of the
Premises by power of sale or a judicial foreclosure, if such should prove
necessary to effect a cure.

         38. DEFINITION OF LANDLORD. The term "Landlord" as used in this Lease,
so far as covenants or obligations on the part of Landlord are concerned, shall
be limited to mean and include only the owner or owners, at the time in
questions, of the fee title to, or a lessee's interest in a ground lease of the
Site or master lease of the Building. In the event of any transfer, assignment
or other conveyance or transfer of any such title or interest, Landlord herein
named (and in case of any subsequent transfers or conveyances, the then grantor)
shall be automatically freed and relieved from and after the date of such
transfer, assignment or conveyance of all liability with respect to the
performance of any covenants or obligations on the part of Landlord contained in
this Lease thereafter to be performed and, without further agreement, the
transferee of such title or interest shall be deemed to have agreed to observe
and perform any and all obligations of Landlord hereunder, during its ownership
of the Premises, Landlord may transfer its interest in the Premises without the
consent of Tenant and such transfer or subsequent transfer shall not be deemed a
violation on Landlord's part of any of the terms and conditions of this Lease.

         39. WAIVER. The failure of Landlord to seek redress for violation of,
or to insist upon strict performance of, any term, covenant or condition of this
Lease or the Rules and Regulations attached hereto as Exhibit "F", shall not be
deemed a waiver of such violation or prevent a subsequent act which would have
originally constituted a violation from having all the force and effect of an
original violation, nor shall the failure of Landlord to enforce any of said
Rules and Regulations against any other tenant of the Building be deemed a
waiver of any such Rule and Regulation, nor shall any custom or practice which
may become established between the parties in the administration of the terms
hereof be deemed a waiver of, or in any way affect, the right of Landlord to
insist upon the performance by Tenant in strict accordance with said terms. The
subsequent acceptance of rent hereunder by Landlord shall not be deemed to be a
waiver of any preceding breach by Tenant of any term, covenant or condition of
this Lease, other than the failure of Tenant to pay the particular rent so
accepted, regardless of Landlord's knowledge of such preceding breach at the
time of acceptance of such rent.

         40. INDENTIFICATION OF TENANT. Unless the provisions of Paragraph 55
herein below are applicable to this Lease, then if more than one person executes
this Lease as Tenant, (a) each of them is jointly and severally liable for the
keeping, observing and performing of all of the terms, covenants, conditions,
provisions and agreements of this Lease to be kept observed and performed by
Tenant, and (b) the term "Tenant" as used in this Lease shall mean and include
each of them jointly and severally and the act of or notice from, or notice or
refund to, or the signature of, any one or more of them, with respect to the
tenancy of this Lease, including, but not limited to, any renewal extension,
expiration, termination or modification of this Lease, shall be binding upon
each and all of the personal executing this Lease as Tenant with the same force
and effect as if each and all of them had so acted or so given or received such
notice or refund or so signed.

         41. PARKING. The use by Tenant, its employees and invitees, of the
parking facilities of the Building shall be on the terms and conditions set
forth in Exhibit F attached hereto and by this reference incorporated herein and
shall be subject to such other agreement between Landlord and Tenant as may
hereinafter be established.





                                       16
<PAGE>   81
         43. TERMS AND HEADINGS. The words "Landlord" and "Tenant" as used
herein shall include the plural as well as the singular. Words used in any
gender include other genders. If there be more than one Tenant, i.e. if two or
more personal or entities are jointly referred to in this Lease as "Tenant," the
obligations hereunder imposed upon Tenant shall be joint and several. The
Paragraph headings of this Lease are not a part of this Lease and shall have no
effect upon the construction or interpretation of any part hereof.

         44. EXAMINATION OF LEASE. Submission of this instrument for examination
or signature by Tenant does not constitute a reservation of or option for Lease,
and it is not effective as a Lease or otherwise until execution by and delivery
to both Landlord and Tenant.

         45. TIME. Time is of the essence with respect to the performance of
every provision of this Lease in which time or performance is a factor.

         46. PRIOR AGREEMENT: AMENDMENTS. This Lease contains all of the
agreements of the parties hereto with respect to any matter covered or mentioned
in this Lease, and no prior agreement or understanding, oral or written, express
or implied, pertaining to any such matter shall be effective for any purpose. No
provision of this Lease may be amended or added to except by an agreement in
writing signed by the parties hereto or their respective successors in interest.
The parties acknowledge that all prior agreements, representations and
negotiations are deemed superseded by the execution of this Lease to the extent
they are not incorporated herein.

         47. SEPARABILITY. Any provision of this Lease which shall prove to be
invalid, void or illegal in no way affects, impairs or invalidates any other
provision hereof, and such other provisions shall remain in full force and
effect.

         48. RECORDING. Neither Landlord nor Tenant shall record this Lease nor
a short memorandum thereof without the consent of the other and if such
recording occurs, it shall be at the sole cost and expense of the party
requesting the recording, including any documentary transfer taxes or other
expenses related to such recordation.

         49. LIMITATION ON LIABILITY. The obligations of Landlord under this
Lease do not constitute personal obligations of the individual partners,
directors, officers or shareholders of Landlord, and Tenant shall not seek
recourse against the individual partners, directors, officers or shareholders of
Landlord or any of their personal assets for satisfaction of any liability in
respect to this Lease. In consideration of the benefits accruing hereunder,
Tenant and all successors and assigns covenant and agree that in the event any
actual or alleged failure, breach or default hereunder by Landlord, the sole and
exclusive remedy shall be against Landlord's interest in the Building.

         50. RIDERS. Clauses, plats and riders, if any, signed by Landlord and
Tenant and affixed to this Lease are a part hereof.

         51. SIGNS. Tenant shall not place any sign upon the Premises or the
Building without Landlord's prior written consent except as specifically stated
in the signage provision, Rider #5.

         52. MODIFICATION OF LENDER. If a connection with obtaining
construction, interim or permanent financing for the Building, the lender shall
request reasonable modifications in this Lease as a condition to such financing,
Tenant will not unreasonably withhold, delay or defer its consent thereto,
provided that such modifications do not increase the obligations of Tenant
hereunder or materially adversely affect the leasehold interest hereby created
or Tenant's rights hereunder.

         53. ACCORD AND SATISFACTION. No payment by Tenant or receipt by
Landlord of a lesser amount than the rent payment herein stipulated shall be
deemed to be other than on account of the rent, nor shall any endorsement or
statement on any check or any letter accompanying any check or payment as rent
be deemed an accord and satisfaction and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
rent or pursue any other remedy provided in this Lease. Tenant agrees that each
of the foregoing covenants and agreements shall be applicable to any covenant or
agreement either expressly contained in this lease or imposed by any status or
at common law.

         54. FINANCIAL STATEMENTS. At any time within reason during the term of
this Lease, Tenant shall, upon ten (10) days prior written notice from Landlord,
provide Landlord with a current financial statement and financial statements of
the two (2) years prior to the current financial statement year. Such statement
shall be prepared in accordance with generally accepted accounting principles
and, if such is the normal practice of Tenant, shall be audited by an
independent certified public accountant.

         55. TENANT AS CORPORATION. If Tenant executes this Lease as a
corporation, then Tenant and the persons executing this Lease on behalf of
Tenant represent and warrant that the individuals executing this Lease on
Tenant's behavior are duly authorized to execute and deliver this Lease on its
behalf in accordance with a duly adopted resolution of the board of directors of
Tenant, a copy of which is to be delivered to Landlord on execution hereof, and
in accordance with the By-Laws of Tenant and that this Lease is binding upon
Tenant in accordance with its terms.

         56. NO PARTNERSHIP OR JOINT VENTURE. Nothing in this Lease shall be
deemed to constitute Landlord and Tenant as partners or joint ventures. It is
the express intent of the parties hereto that their relationship with regard to
this Lease be and remains that of landlord and tenant.

         IN WITNESS WHEREOF, the parties have executed this Lease the day and
year first above written.

         ADJUSTED BASIC RENT. Each year during the term of this Lease other than
the Base Year, the Basic Rent or the prevailing Adjusted Basic Rent, as the case
may be, shall be adjusted for the ensuing twelve (12) months by the use of the
Consumer Price Index (All Urban Consumers component) for the San
Francisco-Oakland Area (1982 - 1984 - 100) published by the Bureau of Labor
Statistics of the U.S. Department of Labor. The Basic Rent will be increased by
the percentage increase, if any, between the latest index published just prior
to the commencement of the Lease Term and the comparable latest index published
just prior to January of the following year to arrive at the Adjusted Basic
Rent. Each year thereafter, the Adjusted Basic Rent will be increased by the
percentage increase, if any, between the index published just prior to January
of the subsequent year and the comparable latest index published just prior to
January of the preceding year.

         In case the U.S. Department of Labor shall discontinue the computation
and publication of said Consumer Price Index or the publication thereof should
be delayed so as to prevent its use hereunder at the times required, there shall
be substituted therefor by Landlord such other index or method of ascertaining
changes in the price level as, in the opinion of Landlord, most closely
resembles the Consumer Price Index and method of arriving at the index figure by
said Bureau.

                               RIDERS 1 THROUGH 9

1. Option to Extend All Initial Terms: If Tenant is not in default in the
performance of any of its obligations under any of Tenant's Leases, Tenant shall
have the right, at its option, to extend the initial terms of all Synon, Inc.'s
Leases in the Building, one time only, for five (5) years, only, following the
expiration dates of the Landlord's (the "Extended Terms"). If Tenant elects not
to extend all Leases, this option shall be deemed null and void. The Leases of
the Premises during the Extended Terms shall be upon the same terms, covenants,
and conditions as are set forth in the Leases other than the rent and the terms
of the leaseholds. If Landlord does not receive from Tenant written notice of
Tenant's exercise of this option for all Leases on or before 5:00 p.m. on
October 1, 1995, (the "Option Notice") this option shall terminate. The monthly
rent for the extended terms shall be the then current market rent for comparable
space; however, the monthly rent shall in no event be less than the highest rent
paid during the initial terms of the Leases, (the "Fair Rental Value") agreed
upon solely by and between land Tenant and their agents appointed for this
purpose. Neither Landlord nor Tenant shall have the right to have a court or any
other third party or entity establish the Fair Rental Value.

If Landlord and Tenant are unable to agree on the Fair Rental Value for the
Extended Terms within sixty (60) days after receipt by Landlord of the Option
Notice, Landlord and Tenant being obligated only to act in good faith, this
option shall terminate, and the Leases shall terminate at the end of their
initial terms.

2. First Right of Notice: During the term of this Lease, Tenant will have the
first right ("First Right") to be notified by Landlord of the availability for
lease of the following spaces: 1100 Larkspur Landing Circle, SUITES 260/290,
255/275/285/299, 165, AND 100, (the "Expansion Spaces"). Prior to the expiration
date of a Lease for any of the Expansion Spaces or upon any of the Expansion
Spaces otherwise becoming available through Landlord (excludes subleases),
Landlord will give Tenant written notice (the "Negotiation Notice"). Tenant
shall have ten (10) business days from receipt of the Negotiation Notice in
which to negotiate with Landlord the terms and conditions of the Lease of the
space referenced in the Negotiation Notice. If the parties are unable to agree
on the terms and conditions of the Lease of said space within said ten (10) day
period, Landlord may lease the space described in the Negotiation Notice to a
third party.

This First Right shall not be applicable to any extension of a Lease by an
existing Tenant nor to any new Lease between Landlord and any existing Tenant of
any of the Expansion Spaces.

This First Right shall terminate and be of no force and effect if, at the time
of the delivery to Tenant of any Negotiation Notice, Tenant is in default of the
performance of any of the covenants, conditions or agreements to be performed by
Tenant under the Lease.

Neither party to the Lease shall have the right to have a court or arbitrator or
other third party set the rent or any of the other terms of the Lease for any of
the Expansion Spaces.

This First Right is personal to Tenant and may not be assigned by Tenant
separately or as a part of this Lease.

<PAGE>   84
3. First Right to Negotiate - Suite 365: On or before January 1, 1992, Tenant
will have the first right ("First Right") to negotiate with Landlord for the
lease of the contiguous 7,513 rentable square feet, commonly known as Suite 365,
(the "Expansion Space"). On or before January 1, 1992 Tenant will give Landlord
written notice (the "Negotiation Notice"). Tenant shall have sixty (60) days
from giving the Negotiation Notice in which to negotiate with Landlord the terms
and conditions of the Lease for Suite 365 which shall commence no sooner than
July 1, 1992, unless existing Tenant in Suite 365 vacates earlier. If the
parties are unable to agree on the terms and conditions of the Lease of said
space within said sixty (60) day period, Landlord may lease the space described
in the Negotiation Notice to a third party. Failure by Tenant to give timely
notice shall render this First Right null and void.

This First Right shall be for a Lease of the Expansion Space for a five (5) year
term, only. All other terms and conditions shall be negotiable in the sixty (60)
day negotiation period.

This First Right shall be exercisable one time only, that being on or before
January 1, 1992 as stated above.

This First Right shall terminate and be of no force and effect if, at the time
of the delivery to Tenant of the Negotiation Notice, Tenant is in default of the
performance of any of the covenants, conditions or agreements to be performed by
Tenant under the Lease.

Neither party to the Lease shall have the right to have a court or arbitrator or
other third party set the rent or any of the other terms of the Lease for the
Expansion Space.

This First Right is personal to Tenant and may not be assigned by Tenant
separately or as a part of this Lease.

4. First Right to Negotiate - Suite 190: During the term of this Lease, Tenant
will have the first right ("First Right") to negotiate with Landlord for the
Lease of the contiguous 952 rentable square feet, commonly known as Suite 190,
(the "Expansion space"), currently leased by R.E. Lewis, (the "Existing
Tenant").

Should Landlord determine that there is space comparable to the Expansion Space
within Larkspur Landing Office Park, this First Right shall be exercisable under
all of the following conditions:

         a) The Existing Tenant executes a lease on comparable space, subject to
         Landlord and Tenant agreeing to terms on the Expansion Space.

         b) Tenant agrees in writing to pay the cost of providing improvements
         in the new location within Larkspur Landing Office Park comparable to
         the improvements of the Existing Tenant's current space.

         c) Tenant agrees in writing to pay the expenses reasonably incurred by
         the Existing Tenant in the relocation to new space including without
         limitation, the costs of moving, telephone relocation, and reasonable
         quantities of new stationery.

Upon the above conditions being met, Landlord shall give written notice to
Tenant of the availability of the Expansion Space (the "Negotiation Notice").

Tenant shall have ten (10) business days from receipt of the Negotiation Notice
in which to negotiate with Landlord the terms and conditions of the Lease of the
space referenced in the Negotiation Notice. If the parties are unable to agree
on the terms and conditions of the Lease of said space within said ten (10) day
period, this First Right shall become null and void.




                                       R-2
<PAGE>   85
This First Right shall terminate and be of no force and effect if, at the time
of the delivery to Tenant of the Negotiation Notice, Tenant is in default of the
performance of any of the covenants, conditions, or agreements to be performed
by Tenant under the Lease.

Neither party to the Lease shall have the right to have a court or arbitrator or
other third party set the rent or any of the other terms of the Lease for the
Expansion Space.

This First Right is personal to Tenant and may not be assigned by Tenant
separately or as a part of the Lease.

5. Signage: Upon at least 56% occupancy of the Building (44,000 Rentable Square
Feet), Tenant, at Tenant's sole cost and expense, shall be entitled to modify
the monument sign in front of Building 1100 to include Tenant's name under the
following conditions:

         a)   Tenant shall be responsible for preparing all plans and obtaining
              any necessary approvals by the City.

         b)   Tenant shall submit signage modification plan to Landlord for
              Landlord's prior approval.

         c)   Any modifications to Building sign shall continue to designate the
              Building address and Leasing Office.

         d)   If at any time Tenant's occupancy of the Building is less than 56%

Preceding calendar year during the term of this Lease, Landlord shall endeavor
to deliver to Tenant a statement ("Estimate Statement") wherein Landlord shall
estimate the Operating Expenses for the current calendar year, and the amount by
which Tenant's Percentage Share of the Operating Expenses on account of the
operation or maintenance of the Building is in excess of the Operating Expenses
Allowance. If Tenant's Percentage Share of the Operating Expenses estimated in
the Estimate Statement exceeds the Operating Expenses Allowance then such excess
amount shall be divided into twelve (12) equal monthly installments and Tenant
shall pay to Landlord, concurrently with the regular monthly rent payment next
due following the receipt of such statement, an amount equal to one (1) monthly
installment multiplied by the number of months from January in the calendar year
in which said statement is submitted to the month of such payment, both months
inclusive. Subsequent installments shall be paid concurrently with the regular
monthly rent payments for the balance of the calendar year and shall continue
until the next calendar year's Estimate Statement is rendered. By the first day
of June of each succeeding calendar year during the term of this Lease, Landlord
shall endeavor to deliver to Tenant a statement ("Actual Statement") wherein
Landlord shall state the actual Operating Expenses for the preceding calendar
year. If the Actual Statement reveals a greater increase in Tenant's Percentage
Share of Operating Expenses than was estimated by Landlord in the Estimated
Statement delivered its provided herein, then upon receipt of the Actual
Statement from Landlord, Tenant shall pay a lump sum equal to said total
increase over the Operating Expenses Allowance, less the total of the monthly
installments of increases set forth on the Estimate Statement which were paid in
the previous calendar year. If, in any calendar year, Tenant's Percentage Share
of Operating Expenses is less than the preceding calendar year, then upon
receipt of Landlord's Actual Statement, any overpayment made by Tenant on the
monthly installment basis provided above shall be credited toward the next
monthly rent falling due and the monthly installment of Tenant's Percentage
Share of Operating Expenses to be paid pursuant to the then current Estimate
Statement shall be adjusted to reflect such lower expenses for the most recent
calendar year, or if this Lease has been terminated, such excess shall be
credited against any amount which Tenant owes Landlord pursuant to this Lease
and, to the extent all amounts which Tenant owes Landlord pursuant to this Lease
have been paid, Landlord shall promptly pay such excess to Tenant. Any delay or
failure by Landlord in delivering any estimate or statement pursuant to this
Paragraph shall not constitute a waiver of its right to require an increase in
rent nor shall it relieve Tenant of its obligations pursuant to this Paragraph,
except that Tenant shall not be obligated to make any payments based on estimate
or statement until ten (10) days after receipt of such estimate or statement.

         (c) Even though the term has expired and Tenant has vacated the
Premises, when the final determination is made of Tenant's Percentage Share of
Operating Expenses for the year in which this Lease terminates, Tenant shall
immediately pay any increase due over the estimated expenses paid and conversely
any overpayment made in the event said expenses decrease shall be immediately
rebated by Landlord to Tenant.

         (d) Notwithstanding anything contained in this Paragraph 6, the rental
payable by Tenant shall in no event be less than the rent specified in Paragraph
5 hereof.

         7. SECURITY DEPOSIT. Tenant has deposited with Landlord the Security
Deposit designated in Subparagraph I (t). Said deposit shall be held by Landlord
as security for the faithful performance by Tenant of all of the terms,
covenants, and conditions of this Lease to be kept and performed by Tenant
during the term hereof. If Tenant defaults with respect to any provision of this
Lease, including but not limited to the provisions relating to the payment of
rent, Landlord may (but shall not be required to) use, apply or retain all or
any part of this Security Deposit for the payment of any rent or any other sum
in default, or for the payment of any other amount which Landlord may spend or
become obligated to spend by reason of Tenant's default or to compensate
Landlord for any loss or damage which Landlord may suffer by reason of Tenant's
default. If any portion of said deposit is so used or applied, Tenant shall,
within ten (10) days after demand therefor, deposit cash with Landlord in an
amount sufficient to restore the Security Deposit to its original amount and
Tenant's failure to do so shall be a material breach of this Lease. Landlord
shall not be required to keep this Security Deposit separate from its general
funds, and Tenant shall not be entitled to interest on such Security Deposit. If
0Tenant shall fully and faithfully perform every provision of this Lease to be
performed by it, the Security Deposit or any balance thereof shall be returned
to Tenant (or, at Landlord's option, to the last assignee of Tenant's interests
hereunder) at the expiration of the Lease term, provided that Landlord may
retain the Security Deposit until such time as any amount due from Tenant in
accordance with Paragraph 5 and 6 hereof has been determined and paid in full.
Should Landlord sell its interest in the Premises during the term hereof and if
Landlord deposits with the purchaser thereof the then unappropriated funds
deposited by Tenant as aforesaid, thereupon Landlord shall be discharged from
any further liability with respect to such Security Deposit.

         8. USE. Tenant shall use the Premises for general office purposes and
purposes incident thereto in compliance with Exhibit H, Hazardous Waste, and

written notice from Landlord, discontinue any use of the Premises which declared
by any governmental authority having jurisdiction to be a violation of any
recorded covenants, conditions and restrictions affecting the Site or of any law
or of said Certificate of Occupancy. Tenant may not offer shared tenant
services,

processing, to any unaffiliated tenant in the Building without Landlord's prior
written consent, which consent may be withheld by Landlord at its sole and
absolute discretion. Tenant shall not install any radio or television antenna,
loudspeaker or other device on the roof or exterior walls of the Building.
Tenant shall not interfere with radio or television broadcasting or reception
from or in the Building or elsewhere. Tenant shall comply with any direction of
any governmental authority having jurisdiction which shall, by reason of the
nature of Tenant's use or occupancy of the Premises, impose any duty, upon
Tenant or Landlord with respect to the Premises or with respect to the use or
occupation thereof. Tenant shall not do or permit to be done anything which will
invalidate or increase the cost of any fire, extended coverage or any other
insurance policy covering the Building and/or property located therein and shall
comply with all rules, orders, regulations and requirements of the Pacific Fire
Rating Bureau or any other organization performing a similar function. Tenant
shall promptly upon demand reimburse Landlord as additional rent for any
additional premium charged for such policy by reason of Tenant's failure to
comply with the provisions of this Paragraph 8. Tenant shall not do or permit
anything to be done in or about the Premises which will in any way obstruct or
interfere with the rights of other tenants or occupants of the Building, or
injure or annoy them, or use or allow the Premises to be used for any improper,
immoral, unlawful or objectionable purpose, nor shall Tenant cause, maintain or
permit any nuisance in, on or about the Promises. Tenant shall not commit or
suffer to be committed any waste in or upon the Premises and shall keep the
Premises in first class repair and appearance. Tenant shall not place a load
upon the Premises exceeding the average pounds of live load per square foot of
floor area specified for the Building by Landlord's architect, with the
partitions to be considered a part of the live load. Landlord reserves the right
to prescribe the weight and position of all safes, files and heavy equipment
which Tenant desires to place in the Premises so as to distribute properly the
weight thereof. Tenant's business machines and mechanical equipment which cause
vibration or noise that may be transmitted to the Building structure or to any
other space in the Building shall be so installed, maintained and used by Tenant
as to eliminate such vibration or noise. Tenant shall be responsible for all
structural engineering required to determine structural load. Tenant shall
fasten all files, bookcases and like furnishings to walls in a manner to prevent
tipping over in the event of earth movements. Landlord shall not be responsible
for any damage or liability for such events.

         9. PAYMENTS AND NOTICES. *Payments will be by check only, unless Tenant
is in default, as per Paragraph 25. All rents and other sums payable by Tenant
to Landlord hereunder shall be paid to Landlord by check, cashier's check, or
cash, at Landlord's option, at the address designated by Landlord in
Subparagraph I (b) above or at such other places as Landlord may hereafter
designate in writing. Any notice required or permitted to be given hereunder
must be in writing and may be given by personal delivery or by mail, and if
given by mail shall be deemed sufficiently given if sent by registered or
certified mail addressed to Tenant at the Building or to Landlord at both of the
addresses designated in Subparagraph 1(b). Either party may by written notice to
the other specify a different address for notice purposes except that Landlord
may in any event use Premises as Tenant's address for notice purposes. If more
than one person or entity constitutes the "Tenant" under this Lease, service of
any notice upon any one of said persons or entities shall be deemed as service
upon all of said persons or entities.

         10. BROKERS. The parties recognize that the brokers who negotiated this
Lease are the brokers whose names are stated Subparagraph l(v), and agree that
Landlord shall be solely responsible for the payment of brokerage commissions to
said brokers, and that Tenant shall have no responsibility therefor. As part of
the consideration for the granting of this Lease, Tenant represents and warrants
to Landlord that to Tenant's knowledge no other broker, agent or finder
negotiated or was instrumental in negotiating or consummating this Lease and
that Tenant knows of no other real estate broker, agent or finder who is, or
might be, entitled to a commission or compensation in connection with this
Lease. Any broker, agent or finder of Tenant whom Tenant has failed to disclose
herein shall be paid by Tenant. Tenant shall hold Landlord harmless from all
damages and indemnify Landlord for all said damages paid or incurred by Landlord
resulting from any claims that may be asserted against Landlord by any broker,
agent or finder undisclosed by Tenant herein.

         11. HOLDING OVER. If Tenant holds over after the expiration or earlier
termination of the term hereof without the express written consent of Landlord,
Tenant shall become a tenant at sufferance only, at a rental rate equal to two
hundred fifty (250%) of the Annual Basic Rent which would be applicable to the
Premises upon the date of such expiration (subject to adjustment as provided in
Paragraph 6 hereof and prorated on a daily basis), and otherwise subject to the
terms, covenants and conditions herein specified, so far as applicable.
Acceptance by Landlord of rent after such expiration or earlier termination
shall not constitute a holdover hereunder or result in a renewal. The foregoing
provisions of this Paragraph 11 are in addition to and do not affect Landlord's
right of re-entry or any rights of Landlord hereunder or as otherwise provided
by law. If Tenant fails to surrender the Premises upon the expiration of this
Lease despite demand to do so by Landlord, Tenant shall indemnify and hold
Landlord harmless from all loss or liability, including without limitation, any
claim made by any succeeding tenant founded on or resulting from such failure to
surrender.

         12.      TAXES ON TENANT'S PROPERTY.

         (a) Tenant shall be liable for and shall pay at least ten (10) days
before delinquency, taxes levied against any personal property or trade fixtures
placed by Tenant in or about the Premises. If any such taxes on Tenant's
personal property or trade fixtures are levied against Landlord or Landlord's
property or if the assessed value of the Premises is increased by the inclusion
therein of a value placed upon such personal property or trade fixtures of
Tenant and if Landlord, after written notice to Tenant, pays the taxes based
upon such increased assessments, which Landlord shall have the right to do
regardless of the validity thereof, but only under proper protest if requested
by Tenant, Tenant shall upon demand repay to Landlord the taxes levied against
Landlord, or the proportion of such taxes resulting from such increase in the
assessment; provided that in any such event, at Tenant's sole cost and expense,
Tenant shall have the right, in the name of Landlord and with Landlord's full
cooperation, to bring suit in any court of competent jurisdiction to recover the
amount of any such taxes so paid under protest, amount so recovered to belong to
Tenant.

and/or paid for by Landlord or Tenant and whether or not affixed to the real
property so as to become a part thereof, are assessed for real property tax
purposes at a




                                        6
<PAGE>   114
valuation higher than the valuation at which Aggregate Improvements conforming
to Landlord's "Building Standard" in other space in the Building are assessed,
then the real property taxes and assessment levied against Landlord or the
property by on of such excess assessed valuation shall be deemed to be taxes
levied against personal property of Tenant and shall be ned by the provisions of
Subparagraph l2(a),above. If the records of the County Assessor are available
and sufficiently ted to serve as a basis for determining whether said Aggregate
Improvements are assessed at a higher valuation than Landlord's "Building
Standard", such records shall be binding on both Landlord and Tenant. If the
records of the County Assessor are not available or sufficiently detailed to
serve as a basis for making said determination, the actual cost of construction
shall be used.

         13. CONDITION OF PREMISES. Tenant acknowledges that neither Landlord
nor any agent of Landlord has made any representation or warranty with respect
to the Premises or the Building or with respect to the suitability of either for
the conduct of Tenant's business. The taking possession of the Premises by
Tenant shall conclusively establish that the Premises and be Building were a
such time in satisfactory condition however, partial occupancy and rent
commencement will not interfere with Landlord's obligation to complete Tenant
Improvements. Without limiting the foregoing, Tenant's execution of the Notice
attached hereto a Exhibit "D" shall constitute a specific acknowledgment and
acceptance of the various start-up inconveniences that may be associated with
the use of the Building Common Areas such as certain construction obstacles
including scaffolding, delays in the use of freight elevator service, certain
elevators not being available to Tenant, the passage of work crews using
elevators, uneven air conditioning service, and other typical conditions
incident to recently constructed office buildings. Further, Tenant's execution
of said Notice shall constitute an acknowledgment, in light of the practical
impossibility of ensuring that every floor slab has been installed with
absolutely no deflection, that all wood floor coverings, wood paneling , and
similar interior Aggregate Improvements have been and/or will be designed to
accommodate the actual floor slab deflection unique to each particular area of
the Premises to be so improved.

         14.      ALTERATIONS.

         (a) Tenant may, at any time and from time to time during the term of
this Lease, at its sole cost and expense, make alterations, additions,
installations, substitutions, improvements and decorations (hereinafter
collectively called "Changes") in and to the Premises, excluding structural
changes, on the following conditions, and providing such Changes will not result
in a violation of or require a change in the Certificate of Occupancy applicable
to the Premises:

         (i) The outside appearance, character or use of the Building shall not
         be affected, and no Changes shall weaken or impair the structural
         strength or, in the opinion of Landlord, lessen the value of the
         Building or create the potential for unusual expenses to be incurred
         upon the removal of Changes and the restoration of the Premises upon
         the termination of this Lease.

         (ii) No part of the Building outside of the Premises shall be
         physically affected.

         the Service Facilities or interfere with the moving of Landlord's
         equipment to or from the enclosures containing the Service Facilities.

         (iv) In performing the work involved in making such Changes, Tenant
         shall be bound by and observe all of the conditions and covenants
         contained in this Paragraph.

         (v) All work shall be done at such times and in such manner as Landlord

         reasonable wear and tear excepted.

         (b) Before proceeding with any Change (exclusive of changes to items
constituting Tenant's Personal Property), Tenant shall submit to Landlord plans
and specifications for the work to be done, which shall require Landlord's
written approval. Landlord shall then prepare or cause to be prepared, at
Tenant's expense, mechanical, electrical and plumbing drawings and may confer
with consultants in connection with the preparation of such drawings and may
also submit to such consultant(s) any of the plans prepared by Tenant. If
Landlord or such consultant(s) shall disapprove of any of the Tenant's plans
Tenant shall be advised of the reasons of such disapproval. In any event, Tenant
agrees to pay to Landlord, as additional rent, the cost of such consultation and
review immediately upon receipt of invoices either from Landlord or such
consultant(s). Any Change for which approval has been received shall be
performed strictly in accordance with the approved plans and specifications and
no amendments or additions to such plans and specifications shall be made
without the prior written consent of Landlord.

         (c) If the proposed Change requires approval by or notice to the lessor
of a superior lease or the holder of a mortgage, no Change shall be proceeded
with until such approval has been received, or such notice has been given, as
the case may be and all applicable conditions and provisions of said superior
lease or mortgage with respect to the proposed Change or ation have been met or
complied with at Tenant's expense; and Landlord, if it approves the Change, will
request such roval or give such notice, as the case may be.

with (i) all laws, rules, orders, ordinances, directions, regulations and
requirements of all governmental authorities, agencies, offices, departments,

Premises, as a part thereof, at the end of the term hereof, except that Landlord

expenses incurred in such removal, including court costs and attorneys' fees and
storage charges on such effects for any length of time that the same shall be in
Landlord's possession or Landlord may, at its option, without notice, sell said
effects, or any of the same, at private sale and without legal process, for such

amounts due under this Lease from Tenant to Landlord and upon the expense
incident to the removal and sale of said effects.

         (i) Subject to Landlord's agreement to minimize any disturbance of
Tenant's use of the Premises, Landlord reserves the right at any time and from

law, order or requirement of any government or other authority and nothing
contained in this Paragraph 14, shall be deemed or construed to impose upon
Landlord any obligation, responsibility or liability whatsoever, for the care,
supervision of repair of the Building or any part thereof other than as

         15.      REPAIRS.

         (a) By entry hereunder, Tenant accepts the Premises as being in good
and sanitary order, condition and repair however, partial occupancy and rent
commencement will not interfere with Landlord's obligation to complete Tenant
Improvements. Tenant shall, when and if needed or whenever requested by Landlord

Premises and every part thereof, to keep, maintain and preserve the Premises in
first class conditions, excepting ordinary wear and tear. Any such maintenance
and repairs shall be performed by Landlord's contractor, or a Landlord's
approved contractor or contractors. All costs and expenses incurred in such
maintenance and repair shall be paid by Tenant within seven (7) days after
billing by Landlord or such contractor or contractors. Tenant shall upon the
expiration or sooner termination of the term hereof surrender the Premises to
Landlord in the same condition as when received, reasonable wear and tear
excepted. Landlord shall have no obligation to alter, remodel, improve, repair,
decorate or paint the Premises or any part thereof and the parties hereto affirm
that Landlord has made no representations to Tenant respecting the condition of
the Premises or the Building except as specifically herein set forth.

         (b) Anything contained in Subparagraph 15(a) above to the contrary
notwithstanding, Landlord shall repair and maintain the structural portions of
the Building, including the basic plumbing, heating, ventilating, air
conditioning and electrical systems installed or furnished by Landlord, unless
such maintenance and repairs are caused in part or in whole by the act, neglect,
fault of or omission of any duty by Tenant, its agents, servants, employees or
invitees, in which case Tenant shall pay to Landlord as additional rent, the
reasonable cost of such maintenance and repairs. Landlord shall not be liable
for any failure to make any such repairs, or to perform any maintenance unless
such failure shall persist for an unreasonable time after written notice of the
need of such repairs or maintenance is given to Landlord by Tenant. Except as
provided in Paragraph 22 hereof there shall be no abatement of rent and no
liability of Landlord by reason of any injury to or interference with Tenant's
business arising from the making of any repairs, alterations or improvements in
or to any portion of the Building or the Premises or in or to fixtures,
appurtenances and equipment therein. Tenant waives the right to make repairs at
Landlord's expense under any law, statute or ordinance now or hereafter in
effect. Notwithstanding anything to the contrary contained in Subparagraphs (a)
and (b) of this Paragraph 15, Tenant shall maintain and repair at its sole cost
and expense, and with maintenance contractors approved by Landlord, all non-base
building facilities, including lavatory, shower, toilet, washbasin and kitchen
facilities and heating and air conditioning systems, including all plumbing
connected to said facilities or systems installed by Tenant or on behalf of
Tenant or existing in the Premises at the time of delivery of possession of the
Premises to Tenant by Landlord. The provisions of the immediately preceding
sentence shall not apply to the basic heating and air conditioning system
provided by Landlord to all tenants of the Building.

         16. LIENS. Tenant shall not permit any mechanic's, materialmen's or
other liens to be filed against the real property of which the Premises form a
part nor against the Tenant's leasehold interest in the Premises. Landlord shall
have the right at all reasonable times to post and keep posted on the Premises
any notices which it deems necessary for protection from such liens. If any such
liens are filed, Landlord may, without waiving its rights and remedies based on
such breach of Tenant and without releasing Tenant from any of its obligations,
cause such liens to be released by any means it shall deem proper, uding payment
in satisfaction of the claim giving rise to such lien. Tenant shall pay to
Landlord at once, upon notice by Landlord, any sum paid by Landlord to remove
such liens, together with interest at the maximum rate per annum permitted by
law from the date of such payment by Landlord.

         17. ENTRY BY LANDLORD. Subject to Landlord's agreement to minimize any
disturbance of Tenant's use of the Premises by exercise of the following rights,
Landlord reserves and shall at any and all times have the right to enter the
Premises to inspect the same, to supply janitor service and any other service to
be provided by Landlord to Tenant herunder, to submit said Premises to
prospective purchasers or, during the last six months of the term of this Lease,
to prospective tenants, to post notices of nonresponsibility, to after, improve
or repair the Premises or any other portion of the Building, all without being
deemed guilty of any eviction of Tenant and without abatement of rent, and may,
in order to carry out such purposes, erect scaffolding and other necessary
structures where reasonably required by the character of the work to be
performed, provided that the business of Tenant shall be interfered with as
little as is reasonably practicable. Tenant hereby waives any claim for damages
for any injury or inconvenience to or interference with Tenant's business, any
loss of occupancy or quiet enjoyment of the Premises and any other loss
occasioned thereby. For each of the aforesaid purposes, Landlord shall at all
times have and retain a key with which to unlock all of the doors in, upon and
about the Premises, excluding Tenant's vaults and safes, and Landlord shall have
the means which Landlord may deem proper to open said doors in an emergency in
order to obtain entry to the Premises, and any entry to the Premises obtained by
Landlord by any of said means, or otherwise, shall not under any circumstances
be construed or deemed to be a forcible or unlawful entry into, or a detainer
of, the Premises, or an eviction of Tenant from the Premises or any portion
thereof, and any damages caused on account thereof shall be paid by Tenant. It
is understood and agreed that no provision of this Lease shall be construed as
obligating Landlord to perform any repairs, alterations or decorations except as
otherwise expressly agreed herein to be performed by Landlord. Landlord shall
attempt in the exercise of its rights under this Paragraph 17 to minimize any
disturbance of Tenant's use and possession of the Premises and to provide as
much notice to Tenant as may be reasonably possible prior to any such exercise
of Landlord's rights under this Paragraph 17.

         18. UTILITIES AND SERVICES. Provided that Tenant is not in default
hereunder, Landlord agrees, during the Lease term, to furnish to the Premises as
part of the Operating Expenses during those hours set forth in the Rules and
Regulations as defined in Paragraph 31 hereof, as may be amended in writing by
Landlord from time to time during the term of this Lease and delivered to
Tenant, reasonable quantities of electric current for normal lighting and
fractional horsepower office machines, water for lavatory and drinking purposes,
heat and air conditioning required in Landlord's judgment for the comfortable
use and occupation of the Premises, janitorial service (including washing of
windows with reasonable frequency as determined by landlord) and elevator
service by non-attended automatic elevators. Landlord shall not be liable for,
and Tenant shall not be led to any abatement or reduction of rent by reason of
Landlord's failure to furnish any of the foregoing when such failure is caused
by accident, breakage, repairs, strikes, lockouts or other labor disturbances or
labor disputes of any character, or for any other causes. If Tenant requires or
utilizes more water or electric power than is considered reasonable or normal by





                                        9
<PAGE>   117
Landlord, Landlord may at its option require Tenant to pay, as additional rent,
the cost, as fairly determined by Landlord, incurred by such extraordinary
usage. In addition, Landlord may install separate meter(s) for the Premises, at
Tenant's sole expense, and Tenant thereafter shall pay all charges of the
utility providing service. Tenant specifically undertakes to install maintain at
Tenant's cost such fire protection equipment including, without limitation,
emergency lighting as required by governmental authority or insurer, and if so
required, Tenant shall appoint one of Tenant's personnel to coordinate with the
fire protection facilities and personnel of Landlord. Any incandescent light
bulbs used in the Premises shall be paid for the Tenant. Upon Tenant's request,
Landlord's personnel shall install incandescent light bulbs or other Building
Nonstandard bulbs in the Premises. Tenant agrees to pay Landlord upon demand
Landlord's cost for all such incandescent light bulbs installed or other
Building Nonstandard improvements including but not limited to metallic trim,
wood floor covering, glass panels, windows, partitions, kitchens and executive
washrooms in the Premises. Landlord shall not be responsible in any manner for
said maintenance, cleaning and repair.

         19. INDEMNIFICATION. To the fullest extent permitted by law Tenant
hereby agrees to defend, indemnity and hold Landlord harmless against and from
any and all claims arising from Tenant's use of the Premises or the conduct of
its business or from any activity, work, or thing done, permitted or suffered by
Tenant, its agents, contractors, employees or invitees in or about the Premises
or elsewhere, and hereby agrees to further indemnify and hold harmless Landlord
against and from any and all claims arising from any breach or default in the
performance of any obligation on Tenant's part to be performed under the terms
of this Lease or arising from any act, neglect, fault or omission of Tenant, or
of its agents, employees or invitees, and from and against all costs, attorneys'
fees, expenses and liabilities incurred in or about such claim or any action or
proceeding brought thereon. In case any action or proceeding is brought against
Landlord by reason of any such claim, Tenant upon notice from Landlord hereby
agrees to defend the same at Tenant's expense by counsel approved in writing by
Landlord. Tenant, as a material part of the consideration to Landlord, hereby
assumes all risk of damage to property or injury to persons in, upon or about
the Premises from any cause whatsoever except that which is caused by the
failure of Landlord to observe any of the terms and conditions of this Lease and
such failure has persisted for an unreasonable period of time after written
notice of such failure, and Tenant hereby waives all its claims in respect
thereof against Landlord.

         20. DAMAGE TO TENANT'S PROPERTY. Notwithstanding the provisions of
Paragraph 19 to the contrary, Landlord or its agents shall not be liable for any
damage to property entrusted to employees of the Building, nor for loss of or
damage to any property by theft or otherwise, nor for any injury or damage to
persons or property resulting from fire, explosion, failing plaster, steams,
gas, electricity, water or rain which may leak from any part of the Building or
from the pipes, appliances or plumbing works therein or from the roof, street or
sub-surface or from any other place or resulting from dampness or any other
patent or latent cause whatsoever. Landlord or its agents shall not be liable
for interference with the light or other incorporeal hereditaments. Tenant shall
give prompt notice to Landlord in case of fire or accidents in the Premises or
in the Building or of defects therein or in the fixtures or equipment located
therein.

         21. INSURANCE.

         (a) During the term hereof, Tenant, at its sole expense, shall obtain
and keep in force the following insurance:

         (i) All Risk insurance upon property owned by Tenant and located in the
         Building or for which Tenant is legally liable, Aggregate Improvements
         (other than "Building Standard Work" as described in Subparagraph l(l)
         hereof), and alterations, in an amount not less than ninety percent
         (90%) of the full replacement cost thereof. All such insurance policies
         shall name Tenant and Landlord as named insured thereunder and, at
         Landlord's request shall same Landlord's mortgagees (and, if
         applicable, ground or primary lessors) as loss payees thereunder, all
         as their respective interests may appear. Landlord will not be required
         to carry insurance of any kind on any "Building Non-Standard Work", as
         described in Subparagraph I (m) hereof, on Tenant's furniture or
         furnishings, or on any of Tenant's fixtures, equipment, improvements,
         or appurtenances under this Lease, and Landlord shall not be obligated
         to repair any damage thereto or replace the same.

         (ii) Comprehensive general liability insurance coverage, including
         personal injury, bodily injury, broad form property damage, operations
         hazard, owner's protective coverage, contractual liability, and
         products and completed operations liability, in limits not less than
         $2,000,000.00 inclusive. All such insurance policies shall name Tenant
         as named insured thereunder and shall name Landlord and Landlord's
         mortgagees (and, if applicable, ground or primary lessors) as
         additional insured thereunder, all as their respective interests may
         appear.

         (iii) Worker's Compensation and Employer's Liability insurance, with a
         waiver of subrogation endorsement in form and amount satisfactory to
         Landlord.

         (iv) [DELETED]

         (v) Liquor liability insurance coverage in limits of not less than Five
         Hundred Thousand Dollars ($500,000) if at any time during the term or
         on any occurrence hereof any alcoholic beverages of any nature are
         served on the Premises.


         (vi) Any other form or forms of insurance as Tenant, Landlord, or
         Landlord's mortgagees or ground or primary lessors may reasonably
         require from time to time in form, in amounts, and for insurance risks
         against which a prudent tenant of a comparable size and in a comparable
         business would protect itself.





                                       10
<PAGE>   118
         (b) All policies shall be issued by insurers that are acceptable to
Landlord and in form satisfactory from time to time to Landlord. Tenant will
deliver certificates of insurance to Landlord as soon as practicable after the
placing of the required insurance, but not later than ten (10) days prior to the
date Tenant takes posession of all or any part of the Premises. All policies
shall contain an undertaking by the insurers to notify Landlord and Landlord's
mortgagees (and, if applicable, ground or primary lessors) in writing, not less
than thirty (30) days before any material change, reduction in coverage,
cancellation or other termination thereof. Ten (10) days prior to the expiration
of any insurance policy, Tenant will provide Landlord with a Certificate of
Insurance extending the term of the original policy or a certified copy of a new
policy extending the required coverage.

         (c) During the Term, Landlord shall insure the Building and the
Building Standard Work (excluding any property which Tenant is obligated to
insure under Subparagraph 21(a) hereof) against damage with All Risk insurance
and public liability insurance, all in such amounts and with such deductions as
Landlord considers appropriate, Landlord may, but shall not be obligated to,
obtain and carry any other form or forms of insurance as it or Landlord's
mortgagees may determine advisable. Notwithstanding any contribution by Tenant
to the cost of insurance premiums, as provided herein, Tenant acknowledges that
it has no right to receive any proceeds from any insurance policies carried by
Landlord.

         (d) Tenant will not keep, use, sell, or offer for sale in, or upon, the
Premises any article which may be prohibited by any insurance policy
periodically in force covering the Building and the Building Standard Work.
Tenant shall promptly comply with all reasonable requirements of the insurance
authority or any present or future insurer relating to the Premises.

         (e) If any of Landlord's insurance policies shall be cancelled or
cancellation shall be threatened or the coverage thereunder reduced or
threatened to be reduced in any way because of the use of the Premises or any
part thereof by Tenant or any assignee or subtenant of Tenant or by anyone
Tenant permits on the Premises and, if Tenant fails to remedy the condition
giving rise to such cancellation, threatened cancellation, reduction of
coverage, threatened reduction of coverage, increase in premiums, or threatened
increase in premiums, within 48 hours after notice thereof, Landlord may, at its
option, either terminate this Lease or enter upon the Premises and attempt to
remedy such condition, and Tenant shall promptly pay the cost thereof to
Landlord as additional rent. Landlord shall not be liable for any damage or
injury caused to any property or of others located on the Premises resulting
from such entry. If Landlord is unable, or elects not, to remedy such condition,
then Landlord shall have all of the remedies provided for in this Lease in the
event of a default by Tenant. Notwithstanding the foregoing provisions of this
Subparagraph 21(e), if Tenant fails to remedy as aforesaid, Tenant shall be in
default of its obligation hereunder and Landlord shall have no obligation to
remedy such default.

         (f) All policies covering real or personal property which either party
obtains affecting the Premises shall include a clause or endorsement denying the
insurer any rights of subrogation against the other party to the extent rights
have been waived by the insured before the occurrence of injury or loss, if same
are obtainable without unreasonable cost. Landlord and Tenant waive any rights
of recovery against the other for injury or loss due to hazards covered by
policies of insurance containing such a waiver of subrogation clause or
endorsement, to the extent of the injury or loss covered thereby.

         22. DAMAGE OR DESTRUCTION.

         (a) In the event the Building and/or the Building Standard Work or any
insured alterations are damaged by fire or other perils covered by Landlord's
extended coverage insurance to an extent not exceeding twenty-five percent (25
%) of the full insurable value thereof and if the damage thereto is such that
the Building and/or the Building Standard Work and any insured alterations may
be repaired, reconstructed or restored within a period of ninety (90) days from
the date of the happening of such casualty and Landlord will receive insurance
proceeds sufficient to cover the cost of such repairs, Landlord shall commence
and proceed diligently with the work of repair, reconstruction and restoration
and the Lease shall continue in full force and effect. If such work or repair,
reconstruction and restoration is such as to require a period longer than ninety
(90) days or exceeds twenty-five percent (25%) of the full insurable value
thereof, or if said insurance proceeds will not be sufficient to cover the cost
of such repairs, Landlord either may elect to so repair, reconstruct or restore
the Building and/or Building Standard Work and any insured alterations and the
Lease shall continue in full force and effect or Landlord may elect not to
repair, reconstruct or restore the Building and/or Building Standard Work and
any insured alterations and the Lease shall in such event terminate. Under any
of the conditions of this Subparagraph 22(a), Landlord shall give written notice
to Tenant of its intention within thirty (30) days from the date of such event
of damage or destruction. In the event Landlord elects not to restore said
Building and/or Building Standard Work and any insured alterations, this Lease
shall be deemed to have terminated as of the date of such partial destruction.

         (b) Upon any termination of this Lease under any of the provisions of
this Paragraph 22, the parties shall be released thereby without further
obligation to the other from the date possession of the Premises is surrendered
to Landlord except for which have therefore accrued and are then unpaid.

         (c) In the event of repair, reconstruction and restoration by Landlord
as herein provided, the rent provided to be paid under this Lease shall be
abated proportionately with the degree to which Tenant's use of the Premises is
impaired during the





                                       11
<PAGE>   119
period of such repair, reconstruction or restoration. Tenant shall not be
entitled to any compensation or damages for loss in the use of the whole or any
part of the Premises and/or any inconvenience, annoyance or loss of business
occasioned by such damage, repair, reconstruction or restoration.

         (d) Tenant shall not be released from any of its obligations under this
Lease except to the extent and upon the conditions expressly stated in this
Paragraph 22. Notwithstanding anything to the contrary contained in this
Paragraph 22, should Landlord be delayed or prevented from repairing or
restoring the damaged Premises within one (1) year after the occurrence of such
damage or destruction by reason of acts of God, war, governmental restrictions,
inability to procure the necessary labor or materials, or other cause beyond me
control of Landlord, Landlord shall be relieved of its obligation to make such
repairs or restoration and Tenant shall be released from its obligations under
this Lease as of the end of said year.

         (e) In the event that damage is due to any cause other than fire or
other peril covered by extended coverage insurance, Landlord may elect to
terminate this Lease.

         (f) It is hereby understood that if Landlord is obligated to or elects
to repair or restore as herein provided, Landlord shall be obligated to make
repairs or restoration only of those portions of the Building and the Premises
which were originally provided at Landlord's expense or which were insured by
either party and the proceeds of such insurance have been received by Landlord,
and the repair and restoration of items not provided at Landlord's expense shall
be the obligation of Tenant.

         (g) Notwithstanding anything to the contrary contained in this
Paragraph 22, Landlord shall not have any obligations whatsoever to repair,
reconstruct or restore the Premises when the damage resulting from any casualty
covered under this Paragraph 22 occurs during the last twelve (12) months of the
term of this Lease or any extension hereof.

         (h) The provisions of California Civil Code 1932, Subsection 2, and
1933, Subsection 4, are hereby waived by Tenant.

         23. EMINENT DOMAIN.

         (a) In case the whole of the Premises, or such part thereof as shall
substantially interfere with Tenant's use and occupancy thereof, shall be taken
for any public or quasi-public purpose by any lawful power or authority by
exercise of the right of appropriation, condemnation or eminent domain, or sold
to prevent such taking, either party shall have the right to terminate this
Lease effective as of the date possession is required to be surrendered to said
authority. Tenant shall not assert any claim against Landlord or the taking
authority for any compensation because of such taking, and Landlord shall be
entitled to receive the entire amount of any award without deduction for any
estate or interest of Tenant. In the event the amount of property or the type of
estate taken shall not substantially interfere with the conduct of Tenant's
business, Landlord shall be entitled to the entire amount of the award without
deduction for any estate or interest of Tenant, and landlord at his option
terminate this Lease. If Landlord does not so elect, Landlord shall promptly
proceed to restore the Premises to unreadable their same condition prior to such
partial taking, and a proportionate allowance shall be made to Tenant for the
rent corresponding to the time during which, and to the part of the Premises of
which, Tenant shall be so deprived on account of such taking and restoration.
Nothing contained in this Paragraph shall be deemed to give Landlord any
interest in any award separately made to Tenant for the taking of personal
property and trade fixtures belonging to Tenant or for moving costs incurred by
Tenant in relocating Tenant's business.

         (b) In the event of taking of the Premises or any part thereof for
temporary use, (i) this Lease shall be and remain unaffected thereby and rent
shall not abate, and (ii) Tenant shall be entitled to receive for itself such
portion or portions of any award made for such use with respect to the period of
the taking which is within the term, provided that if such taking shall remain
in force at the expiration or earlier termination of this Lease, Tenant shall
then pay to Landlord a sum equal to the reasonable cost of performing Tenant's
obligations under Paragraph 15 with respect to surrender of the Premises and
upon such payment shall be excused from such obligations. For purpose of this
Subparagraph 23(b), a temporary taking shall be defined as a taking for a period
of 270 days or less.

         24. BANKRUPTCY. If Tenant shall file a petition in bankruptcy under any
Chapter of federal bankruptcy law as then in effect, or if Tenant be adjudicated
a bankrupt in involuntary bankruptcy proceedings and such adjudication shall not
have been vacated within thirty (30) days from the date thereof, or if a
receiver or trustee be appointed of Tenant's property and the order appointing
such receiver or trustee not be set aside or vacated within thirty (30) days
after the entry thereof, or if Tenant shall assign Tenant's estate or effects
for the benefit of creditors, or if this Lease shall otherwise by operation of
law pass to any person or persons other than Tenant, then and in any such event
Landlord may, if Landlord so elects, with or without notice of such election and
with or without entry or action by Landlord, forthwith terminate this Lease.
Notwithstanding any other provisions of this Lease, Landlord, in addition to any
and all rights and remedies allowed by law or equity, shall upon such
termination be entitled to recover damages in the amount provided in
Subparagraph 25(b) below and neither Tenant nor any person claiming through or
under Tenant or by virtue of any statute or order of any court shall be entitled
to possession of the Premises but shall forthwith quit and surrender the
Premises to Landlord. Nothing herein contained shall limit or prejudice the
right of Landlord to prove and obtain as damages by reason of any such
termination an amount equal to the maximum allowed by any statute or rule of law
in effect at the time when, and governing the proceedings in which, such damages
are to be proved, whether or not such amount be greater, equal to, or less than
the amount of damages recoverable under the provisions of this Paragraph 24.

         25. DEFAULTS AND REMEDIES.

         (a) The occurrence of any one or more of the following events shall
constitute a default hereunder by Tenant:





                                       12
<PAGE>   120
         (i) The vacation or abandonment of the Premises by Tenant. Abandonment
         is herein defined to included, But is not limited, to, any absence by
         Tenant from the Premises for five (5) days or longer while in default
         of any provision of this Lease.

         (ii) The failure by Tenant to make any payment of rent or additional
         rent or any other payment required to be made by Tenant hereunder, as
         and when due.

         (iii) The failure by Tenant to observe or perform any of the express or
         implied covenants or provisions of this Lease to be observed or
         performed by Tenant, other than as specified in Subparagraph 25(a)(i)
         or (ii) above, where such failure shall continue for a period of ten
         (10) days after written notice thereof from Landlord to Tenant;
         provided, however, that any such notice shall be in lieu of, and not in
         addition to, any notice required under California Code of Civil
         Procedure 1161; provided, further, that if the nature of Tenant's
         default is such that more than ten (10) days are reasonably required
         for its cure, then Tenant shall not be deemed to be in default if
         Tenant shall commence such cure within said ten-day period and
         thereafter diligently prosecute such cure to completion, which
         completion shall occur not later than sixty (60) days from the date of
         such notice from Landlord.

         (iv) (1) The making by Tenant of any general assignment for the benefit
         of creditors; (2) the filing by or against Tenant of a petition to have
         Tenant adjudged a bankrupt or a petition for reorganization or
         arrangement under any law relating to bankruptcy (unless, in the case
         of a petition filed against Tenant, the same is dismissed within thirty
         (30) days); (3) the appointment of a trustee or receiver to take
         possession of substantially all of Tenant's assets located at the
         Premises or of Tenant's interest in this Lease, where possession is not
         restored to Tenant within thirty (30) days; or (4) the attachment,
         execution or other judicial seizure of substantially all of Tenant's
         assets located at the Premises or of Tenant's interest in this Lease
         where such seizure is not discharged within thirty (30) days.

         (b) In the event of any such default by Tenant, in addition to any
other remedies available to Landlord at law or in equity, Landlord shall have
the immediate option to terminate this Lease and all rights of Tenant hereunder.
In the event that Landlord shall elect to so terminate this lease then Landlord
may recover from Tenant:

         (i) the worth at the time of award of any unpaid rent which had been
         earned at the time of such termination; plus

         (ii) the worth at the time of award of the amount by which the unpaid
         rent which would have been earned after termination until the time of
         award exceeds the amount of such rental loss that Tenant proves could
         have been reasonably avoided; plus

         (iii) the worth at the time of award of the amount by which the unpaid
         rent for the balance of the term after the time of award exceeds the
         amount of such rental loss that Tenant proves could be reasonably
         avoided; plus

         (iv) any other amount necessary to compensate Landlord for all the
         detriment proximately caused by Tenant's failure to perform his
         obligations under this Lease or which in the ordinary course of things
         would be likely to result therefrom.

         As used in Subparagraphs 25(b)(i) and (ii) above, the "worth at the
time of award' is computed by allowing interest at the maximum rate permitted by
law per annum. As used in Subparagraph 25(b)(iii)above, the "worth at the time
of award" is computed by discounting such amount at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one percent
(1%).

         (c) In the event of any such default by Tenant, Landlord shall also
have the right, with or without terminating this Lease, to re-enter the Premises
and remove all persons and property from the Premises. Such property may be
removed and stored in a public warehouse or elsewhere at the cost of and for the
account of Tenant for such period of time as may be required by applicable law
after which time Landlord may dispose of such property in accordance with
applicable law. No re-entry or taking possession of the Premises by Landlord
pursuant to this Subparagraph 25(c) shall be construed as an election to
terminate this Lease unless a written notice of such intention be given to
Tenant or unless the termination thereof be decreed by a court of competent
jurisdiction.

         (d) All rights, options' and remedies of Landlord contained in this
Lease shall be construed and held to be cumulative, and no one of them shall be
exclusive of the other, and Landlord shall have the right to pursue any one or
all of such remedies or any other remedy or relief which may be provided by law,
whether or not stated in this Lease. No waiver of any default of Tenant
hereunder shall be implied from any acceptance by Landlord of any rent or other
payments due hereunder or any omission by Landlord to take any action on account
of such default if such default persists or is repeated, and no express waiver
shall affect defaults other than as specified in said waiver. The consent or
approval or Landlord to or of any act by Tenant requiring Landlord's consent or
approval shall not be deemed to waive or render unnecessary Landlord's consent
or approval to or of any subsequent similar acts by Tenant.

         26. ASSIGNMENT AND SUBLETTING. Tenant shall not voluntarily assign or
encumber its interest in this Lease or in the Premises, or sublease all or any
part of the Premises, or allow any other person or entity to occupy or use all
or any part of the Premises, without first obtaining Landlord's prior written
consent. Any assignment, encumbrance or sublease without Landlord's prior
written consent shall be voidable, at Landlord's election, and shall constitute
a default. For purpose hereof, the event Tenant is a partnership, a withdrawal
or change of partners, or change of ownership of partners, owning more
unreadable a fifty percent (50%) interest in the partnership, or if Tenant is a
corporation, any transfer of fifty percent (50%) of its Stock, shall constitute
a voluntary assignment and shall be subject to these provisions. No consent to
any assignment, encumbrance, or sublease shall constitute a further waiver of
the provisions of this Paragraph. Tenant shall notify Landlord




                                       13
<PAGE>   121
in writing of Tenant's intent to assign encumber, or sublease this lease, the
name of the proposed assignee or sublessee, information concerning the financial
responsibility of the proposed assignee or sublessee and the terms of the
proposed assignment or subletting, and Landlord shall, within thirty (30) days
of receipt of such written notice, and additional information requested by
Landlord concerning the proposed assignee's or sublessee's financial
responsibility, elect one of the following:

         (a) Consent to such proposed assignment, encumbrance or sublease;

         (b) Refuse such consent, which refusal shall be on reasonable grounds;

         (c) Elect to terminate this Lease, or in the case of a partial
             sublease, terminate this Lease as to the portion of the Premises
             proposed to be sublet.

Without limiting Landlord's grounds for disapproval, Landlord's disapproval
shall be deemed reasonable if it is based on Landlord's analysis of (a) the
proposed assignee's or sublessee's credit, character and business or
professional standing, (b) whether the assignee's or sublessee's use and
occupancy of the Premises will be consistent with Subparagraph 1(u) and
Paragraph 8 of this Lease and whether assignee's proposed intensity of use is
consistent with that shown by Tenant, (c) whether the proposed assignee or
sublessee is a then existing or prospective tenant of the Building, as a
condition for granting its consent to any assignment, encumbrance or sublease.
Landlord may require that the rent payable by such assignee or sublessee is at
the then current published rental rates for the Premises or comparable premises
in the Building, but not less than the then current Annual Basic Rent under this
Lease and may require that the assignee or sublessee remit directly to Landlord
on a monthly basis, all monies due to Tenant by said assignee or sublessee. In
the event that Landlord shall consent to any assignment or sublease under the
provisions of this Paragraph 26, Tenant shall pay Landlord's processing costs
and attorneys' fees incurred in giving such consent. If for any proposed
assignment or sublease Tenant receives rent or other consideration, either
initially or over the term of the assignment or sublease, in excess of the rent
called for hereunder, or, in case of the sublease of a portion of the Premises,
in excess of such rent fairly allocable to such portion, after appropriate
adjustments to assure that all other payments called for hereunder are taken
into account, Tenant shall pay to Landlord as additional rent hereunder all of
the excess of each such payment of rent or other consideration received by
Tenant promptly after its receipt. Landlord's waiver or consent to any
assignment or subletting shall not relieve Tenant from any obligation under this
Lease. Occupancy of all or part of the Premises by parent, subsidiary, or
affiliated companies of Tenant shall not be deemed an assignment or subletting.
If Tenant requests Landlord's consent to any assignment of this Lease or any
subletting of all or a portion of the Premises, Landlord shall have the right,
to be exercised by giving written notice to Tenant within thirty (30) days of
receipt by Landlord of the financial responsibility information required by this
Paragraph 26 to terminate this Lease effective as of the date Tenant proposes to
assign this Lease or sublet all or a portion of the Premises. Landlord's right
to terminate this lease as to all or a portion of the Premises on assignment or
subletting shall not terminate as a result of Landlord's consent to the
assignment of this Lease or the subletting of all or a portion of the Premises,
or Landlord's failure exercise this right with respect to any assignment or
subletting.

         27. QUIET ENJOYMENT. Landlord covenants and agrees with Tenant that
upon Tenant paying the rent required under this Lease and paying all other
charges and performing all of the covenants and provisions aforesaid on Tenant's
part to be observed and performed under this Lease, Tenant shall and may
peaceably and quietly have, hold and enjoy the Premises in accordance with this
Lease.

         28. SUBORDINATION. Without the necessity of any additional document
being executed by Tenant for the purpose of effecting a subordination, and at
the election of Landlord or any first mortgagee with a lien on the Building or
any ground lessor with respect to the Building, this lease shall be subject and
subordinate at all times to; (a) all ground leases or underlying leases which
may now exist or hereafter be executed affecting the Building or the land upon
which the Building is situated or both, and (b) the lien of any mortgage or deed
of trust which may now exist or hereafter be executed in any amount for which
the Building, land, ground leases or underlying leases, or Landlord's interest
or estate in any of said items is specified as security. Notwithstanding the
foregoing, Landlord shall have the right to subordinate or cause to be
subordinated any such ground leases or underlying leases or any such liens to
this lease. In the event that any ground lease or underlying lease terminates
for any reason or any mortgage or deed of trust is foreclosed or a conveyance in
lieu of foreclosure is made for any reason, Tenant shall, if requested by the
ground lessor, mortgagee or beneficiary, as applicable, attorn to and become the
Tenant of the successor in interest to Landlord and in such event Tenant's right
to possession of the Premises shall not be disturbed if Tenant is not in default
and so long as Tenant shall pay the rent and all other amounts required to be
paid to Landlord pursuant to the terms hereof and observe and perform all of the
provisions of this Lease, unless the Lease is otherwise terminated pursuant to
its terms. Tenant covenants and agrees to execute and deliver, upon demand by
Landlord and in the form requested by Landlord, any additional documents
evidencing the priority or subordination of this Lease with respect to any such
ground leases or underlying leases or the lien of any such mortgage or deed of
trust. Should Tenant fail to sign and return any such documents within ten (10)
business days of receipt, Tenant shall be in default, and Landlord may, at
Landlord's option, terminate this Lease provided written notice of such
termination is received by Tenant prior to Landlord's receipt of such documents.

         29. ESTOPPEL CERTIFICATE.

         (a) Within ten (10) days following any written request which Landlord
may make from time to time, Tenant shall execute and deliver to Landlord a
statement, in a form substantially similar to the form of Exhibit "E" attached
hereto, certifying; (i) the Commencement Date of this Lease; (ii) the fact that
this Lease is unmodified and in full force and effect or, if there have been
modifications hereto, that this Lease is in full force and effect, as modified,
and stating the date and nature of such modifications); (iii) the date to which
the rental and other sums payable under this Lease have been paid; (iv) the fact
that there are no current defaults under this Lease by either Landlord or Tenant
except as specified in Tenant's




                                       14
<PAGE>   122
statement; and (v) such other matters requested by Landlord. Landlord and Tenant
intend that any statement delivered pursuant to this Paragraph 29 may be relied
upon by any mortgagee, beneficiary, purchaser or prospective purchaser of the
Building or any interest therein.

         (b) Tenant's failure to deliver such statement within such time shall
be conclusive upon Tenant (i) that this Lease is in full force and effect,
without modification except as may be represented by Landlord, (ii) that there
are no uncured defaults in Landlord's performances, and (iii) that not more than
one (1) month's rent has been paid in advance, except as provided in Paragraph
36 hereof. Tenant's failure to deliver said statement to Landlord within ten
(10) working days of receipt shall constitute a default under this Lease, and
Landlord may, at Landlord's option, terminate the Lease, provided written notice
of such termination is received by Tenant prior to Landlord's receipt of said
statement.

         30. BUILDING PLANNING. In the event Landlord requires the Premises for
use in conjunction with another suite or for other reasons connected with the
Building planning program, upon notifying Tenant in writing, Landlord shall have
the right to move Tenant to other comparable space in the Building of which the
Premises forms a part, at Landlord's sole cost and expense including all of
Tenant's moving expenses, telephone installation and stationery reprinting
charges, and the terms and conditions of the original Lease shall remain in full
force and effect, save and excepting that a revised Exhibit "A" shall become
part of this Lease and shall reflect the location of the new space and Paragraph
1 of this Lease shall be amended to include and state all correct data as to the
new space.

         31. RULES AND REGULATIONS. Tenant shall faithfully observe and comply
with the "Rules and Regulations," a copy of which is attached hereto and marked
Exhibit "F", and all reasonable and nondiscriminatory modifications thereof and
additions thereto from time to time put into effect by Landlord. Landlord shall
not be responsible to Tenant for the violation or nonperformance by any other
tenant or occupant of the Building of any of said Rules and Regulations.

         32. CONFLICT OF LAWS. This Lease shall be governed by and construed
pursuant to the laws of the State of California.

         33. SUCCESSORS AND ASSIGNS. Except as otherwise provided in this Lease,
all of the covenants, conditions and provisions of this Lease shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
heirs, personal representative, successors and assigns.

         34. SURRENDER OF PREMISES. The voluntary or other surrender of this
Lease by Tenant, or a mutual cancellation thereof, shall not work a merger, and
shall, at the option of Landlord, operate as an assignment to it of any or all
subleases or subtenancies. Upon the expiration or termination of this Lease,
Tenant shall peaceably surrender the Premises and all alterations and additions
thereto broom-clean, in good order, repair and condition, reasonable wear and
tear excepted, and shall comply with the provisions of Subparagraphs 14(g) and
14(h). The delivery of keys to any employee of Landlord or to Landlord's agent
or any employee thereof shall not be sufficient to constitute a termination of
this Lease or a surrender of the Premises.

         35. PROFESSIONAL FEES.

         (a) In the event that Landlord should bring suit for the possession of
the Premises, for the recovery of any sum due under this Lease, or because of
the breach of any provisions of this Lease, or for any other relief against
Tenant hereunder, or should either party bring suit against the other with
respect to matters arising from or growing out of this Lease, then all costs and
expenses, including without limitation, its actual professional fees such as
appraisers', accountants' and attorneys' fees, incurred by the prevailing part
therein shall be paid by the other party, which obligation on the part of the
other party shall be deemed to have accrued on the date of the commencement of
such action and shall be enforceable whether or not the action is prosecuted to
judgment.

         (b) Should Landlord be named as a defendant in any suit brought against
Tenant in connection with or arising out of Tenant's occupancy hereunder, Tenant
shall pay to Landlord its costs and expenses incurred in such suit, including
without limitation, its actual professional fees such as appraiser's,
accountants' and attorneys' fees.

         36. PERFORMANCE BY TENANT. All covenants and agreements to be performed
by Tenant under any of the terms of this Lease shall be performed by Tenant at
Tenant's sole cost and expense and without any abatement of rent. Tenant
acknowledges that the late payment by Tenant to Landlord of any sums due under
this Lease will cause Landlord to incur costs not contemplated by this Lease,
the exact amount of such cost being extremely difficult and impractical to fix.
Such costs include, without limitation, processing and accounting charges, and
late charges that may be imposed on Landlord by the terms of any encumbrance and
note secured by any encumbrance covering the Premises or the Building of which
the Premises are a part. Therefore if any monthly installment of Annual Basic
Rent is not received by Landlord by the date when due, or if Tenant fails to pay
any other sum of money due hereunder and such failure continues for ten (10)
days after notice thereof by Landlord, Tenant shall pay to Landlord, as
additional rent, the sum of five percent (5 %) of the overdue amount as a late
charge. Such overdue amount shall also bear interest, as additional rent, at the
maximum rate permissible by law calculated, as appropriate, from the date either
(a) the monthly installment of Annual Basic Rent is due, or (b) of receipt of
said notice, until the date of payment to Landlord. Landlord's acceptance of any
late charge or interest shall not constitute a waiver of Tenant's default with
respect to the overdue amount or prevent Landlord from exercising any of the
other rights and remedies available to Landlord under this Lease or any law now
or hereafter in effect. Further, in the event such late charge is imposed
Landlord for two (2) consecutive months for whatever reason, Landlord shall have
the option to require that, beginning It the first payment of rent due following
the imposition of the second consecutive late charge, rent shall no longer be
paid monthly installments but shall be payable three (3) months in advance.




                                       15
<PAGE>   123
         37. MORTGAGEE AND SENIOR LESSOR PROTECTION. No act or failure to act on
the part of Landlord which would entitle Tenant under the terms of the Lease, or
by law, to be relieved of Tenant's obligations hereunder or to terminate this
Lease, shall result in a release of such obligations or a termination of this
Lease unless (a) Tenant has given notice by stered or certified mail to any
beneficiary of a deed of trust or mortgage covering the Premises and to the
Lessor under master or ground lease covering the Building, the Site or any
interest therein whose identity and address shall have been furnished to Tenant,
and (b) Tenant offers such beneficiary, mortgagee or Lessor a reasonable
opportunity to cure the default, including time to obtain possession of the
Premises by power of sale or of judicial foreclosure, if such should prove
necessary to effect a cure.

         38. DEFINITION OF LANDLORD. The term "Landlord" as used in this Lease,
so far as covenants or obligations on the part of Landlord are concerned, shall
be limited to mean and include only the owner or owners, at the time in
question, of the fee title to, or a lessee's interest in a ground lease of the
Site or master lease of the Building. In the event of any transfer, assignment
or other conveyance or transfer of any such title or interest, Landlord herein
named (and in case of any subsequent transfers or conveyances, the then grantor)
shall be automatically freed and relieved from and after the date of such
transfer, assignment or conveyance of all liability with respect to the
performance of any covenants or obligations on the part of Landlord contained in
this Lease thereafter to be performed and, without further agreement, the
transferee of such title or interest shall be deemed to have agreed to observe
and perform any and all obligations of Landlord hereunder, during its ownership
of the Premises, Landlord may transfer its interest in the Premises without the
consent of Tenant and such transfer or subsequent transfer shall not be deemed a
violation on Landlord's part of any of the terms and conditions of this Lease.

         39. WAIVER. The failure of Landlord to seek redress for violation of,
or to insist upon strict performance of, any term, covenant or condition of this
Lease or the Rules and Regulations attached hereto as Exhibit "F", shall not be
deemed a waiver of such violation or prevent a subsequent act which would have
originally constituted a violation from having all the force and effect of an
original violation, nor shall the failure of Landlord to enforce any of said
Rules and Regulations against any other tenant of the Building be deemed a
waiver of any such Rule or Regulation, nor shall any custom or practice which
may become established between the parties in the administration of the terms
hereof be deemed a waiver of, or in any way affect, the right of Landlord to
insist upon the performance by Tenant in strict accordance with said terms. The
subsequent acceptance of rent hereunder by Landlord shall not be deemed to be a
waiver of any preceding breach by Tenant of any term, covenant or condition of
this Lease, other than the failure of Tenant to pay the particular rent so
accepted, regardless of Landlord's knowledge of such preceding breach at the
time of acceptance of such rent.

         40. IDENTIFICATION OF TENANT. Unless the provisions of Paragraph 55
herein below are applicable to this Lease, then if more than one person executes
this Lease as Tenant, (a) each of them is jointly and severally liable for the
keeping, observing and performing of all of the terms, covenants, conditions,
provisions and agreements of this Lease to be kept, observed and performed by
Tenant, and (b) the term "Tenant" as used in this Lease shall mean and include
each of them tly and severally and the act of or notice from, or notice or
refund to, or the signature of, any one or more of them, with respect to the
tenancy or this Lease, including, but not limited to, any renewal, extension,
expiration, termination or modification of this Lease, shall be binding upon
each and all of the persons executing this Lease as Tenant with the same force
and effect as if each and all of them had so acted or so given or received such
notice or refund or so signed.

         41. PARKING. The use by Tenant, its employees and invitees, of the
parking facilities of the Building shall be on the terms and conditions set
forth in Exhibit F attached hereto and by this reference incorporated herein and
shall be subject to such other agreement between Landlord and Tenant as may
hereinafter be established.

upon the construction or interpretation of any part hereof.

every provision of this Lease in which time or performance is a factor.

agreements of the parties hereto with respect to any matter covered or mentioned

provision of this Lease may be amended or added to except by an agreement in
writing signed by the parties hereto or their respective successors in interest.
The parties acknowledge that all prior agreements, representations and
negotiations are deemed superseded by the execution of this Lease to the extent
they are not incorporated herein.

         47. SEPARABILITY. Any provision of this Lease which shall prove to be
invalid, void or illegal in no way affects, impairs or invalidates any other
provision hereof, and such other provisions shall remain in full force and
effect.

         48. RECORDING. Neither Landlord nor Tenant shall record this Lease nor
a short memorandum thereof without the consent of the other and if such
recording occurs, it shall be at the sole cost and expense of the party
requesting the recording, including any documentary transfer taxes or other
expenses related to such recordation.

         49. LIMITATION ON LIABILITY. The obligations of Landlord under this
Lease do not constitute personal obligations of the individual partners,
directors, officers or shareholders of Landlord, and Tenant shall not seek
recourse against the individual partners, directors, officers or shareholders of
Landlord or any of their personal assets for satisfaction of any liability in
respect to this Lease. In consideration of the benefits accruing hereunder,
Tenant and all successors and assigns covenant and agree that in the event of
any actual or alleged failure, breach or default hereunder by Landlord, the sole

         52. MODIFICATION OF LENDER. If in connection with obtaining
construction, interim or permanent financing for the Building, the lender shall
request reasonable modifications in this Lease as a condition to such financing,
Tenant will not unreasonably withhold, delay or defer its consent thereto,
provided that such modifications do not increase the obligations of Tenant
hereunder or materially adversely affect the leasehold interest hereby created
or Tenant's rights hereunder.

         53. ACCORD AND SATISFACTION. No payment by Tenant or receipt by
Landlord of a lesser amount than the rent payment herein stipulated shall be
deemed to be other than on account of the rent, nor shall any endorsement or
statement on any check or any letter accompanying any check or payment as rent
be deemed an accord and satisfaction and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
rent or pursue any other remedy provided in this Lease. Tenant agrees that each
of the foregoing covenants and agreements shall be applicable to any covenant or
agreement either expressly contained in this lease or imposed by any statute or
at common law.

and, if such is the normal practice of Tenant, shall be audited by an
independent certified public accountant.

         55. TENANT AS CORPORATION. If Tenant executes this Lease as a
corporation, then Tenant and the persons executing this Lease on behalf of
Tenant represent and warrant that the individuals executing this Lease on
Tenant's behalf are duly authorized to execute and deliver this Lease on its
behalf in accordance with a duly adopted resolution of the board of directors of
Tenant, a copy of which is to be delivered to Landlord on execution hereof, and
in accordance with the By-Laws of Tenant and that this Lease is binding upon
Tenant in accordance with its terms.

         56. NO PARTNERSHIP OR JOINT VENTURE. Nothing in this Lease shall be

Continued from Page 3, "Rent Escalation":

         ADJUSTED BASIC RENT. Each year during the term of this Lease other than
the Base Year, the Basic Rent or the prevailing Adjusted Basic Rent, as the case
may be, shall be adjusted for the ensuing twelve (12) months by the use of the
Consumer Price Index (All Urban Consumers component) for the San
Francisco-Oakland Area (1982 - 1984 - 100) published by the Bureau of Labor
Statistics of the U.S. Department of Labor. he Basic Rent will be increased by
the percentage increase, if any, between the latest index published just prior
to the commencement of the Lease Term and the comparable latest index published
just prior to January of the following year to arrive at the Adjusted Basic
Rent. Each year thereafter, the Adjusted Basic Rent will be increased by the
percentage increase, if any, between the index published just prior to January
of the subsequent year and the comparable latest index published just prior to
January of the preceding year.

         In case the U.S. Department of Labor shall discontinue the computation
and publication of said Consumer Price Index or the publication thereof should
be delayed so as to prevent its use hereunder at the times required, there shall
be substituted therefor by Landlord such other index or method of ascertaining
changes in the price level as, in the opinion of Landlord, most closely
resembles the Consumer Price Index and method of arriving at the index figure by
said Bureau.

                              WORK LETTER AGREEMENT

         This Work Letter Agreement is entered into as of the 22nd day of
Sept.,1992 by and between Lincoln Property Company, N.C., Inc. ("Landlord"), and
Synon, Inc. ("Tenant").

                                    RECITALS:

         A. Concurrently with the execution of this Work Letter Agreement,
Landlord and Tenant have entered into a lease (the "Lease") covering certain
premises (the "Premises") more particularly described in Exhibit A attached to
the Lease.

         B. In order to induce Tenant to enter into the Lease (which is hereby
incorporated by reference to the extent that the provisions of this Work Letter
Agreement may apply thereto) and in consideration of the mutual covenants
hereinafter contained, Landlord and Tenant hereby agree as follows: Landlord to
provide a maximum Tenant Improvement contribution of $6.00 per rentable square

                      STANDARDS FOR UTILITIES AND SERVICES

         The following Standards for utilities and Services are in effect.

conditions, provisions or agreements of this Lease, Landlord shall:

         (a) Provide non-attended automatic elevator facilities Monday through
Friday, except holidays from 8 a.m. to 6 p.m.

(and other times for a reasonable additional charge to be fixed by Landlord),
ventilate the Premises and furnish air conditioning or heating on such days and
hours, when in the judgment of Landlord it may be required for the comfortable
occupancy of the Premises. The air conditioning system achieves maximum cooling
when the window coverings are closed. Tenant agrees to cooperate fully at all
times with Landlord, and to abide by all regulations and requirements which
Landlord may prescribe for the proper function and protection of said air
conditioning system. Tenant agrees not to connect any apparatus, device conduit
or pipe to the Building chilled and hot water air conditioning supply lines.
Tenant further agrees that neither Tenant nor its servants, employees, agents,
visitors, licensees or contractors shall at any time enter mechanical
installations or facilities of the Building or adjust, tamper with, touch or
otherwise in any manner affect said installations or facilities. The cost of
maintenance and service calls to adjust and regulate the air conditioning system
shall be charged to tenant if the need for maintenance work results from either
Tenant's adjustment of room thermostats or Tenant's failure to comply with it
obligations under this section, including keeping window coverings closed as
needed. Such work shall be charged at hourly rates equal to then-current
journeymen's wages for air conditioning mechanics.

         (c) Landlord shall furnish to the Premises, during the usual business
hours on business days, electric current as required by the Building standard

not to exceed .025 KWH per square fool per normal business day. Tenant agrees,
should its electrical installation or electrical consumption be in excess of the
aforesaid quantity or extend beyond normal business hours, to reimburse Landlord
monthly for the measured consumption at the average cost per kilowatt hour
charged to the Building during the period. If a separate meter is not installed
at Tenant's cost, such excess cost will be established by an estimate agreed
upon by Landlord and Tenant, and if the parties fail to agree, as established by
an independent licensed engineer. Said estimates to be reviewed and adjusted
quarterly. Tenant agrees not to use any apparatus or device in, or upon, or
about the Premises which may in any way increase the amount of such services
usually furnished or supplied to said Premises, and Tenant further agrees not to
connect any apparatus or device with wires, conduits or pipes, or other means by
which such services are supplied, for the purpose of using additional or unusual
amounts of such services without written consent of Landlord. Should Tenant use
the same to excess, the refusal on the part of Tenant to pay upon demand of
Landlord the amount established by Landlord for such excess charge shall
constitute a breach of the obligation to pay rent under this Lease and shall
entitle Landlord to the rights therein granted for such breach. At all times
Tenant's use of electric current shall never exceed the capacity of the feeders
to the Building or the risers or wiring installation.

         (d) Water will be available in public areas for drinking and lavatory
purposes only, but if Tenant requires, uses or consumes water for any Purposes
in addition to ordinary drinking and lavatory purposes of which fact Tenant
constitutes Landlord to be the sole judge, Landlord may install a water meter
and thereby measure Tenant's water consumption for all purposes. Tenant shall
pay Landlord for the cost of the meter and the cost of the installation thereof
and throughout the duration of Tenant's occupancy Tenant shall keep said meter
and installation equipment in good working order and repair at Tenant's own cost
and expense, in default of which Landlord may cause such meter and equipment to
be replaced or repaired and collect the cost thereof from Tenant. Tenant agrees
to pay for water consumed, as shown on said meter, as and when bills are
rendered, and on default in making such payment. Landlord may pay such charges
and collect the same from Tenant. Any such costs or expenses incurred, or
payments made by Landlord for any of the reasons or purposes hereinabove stated
shall be deemed to be additional rent payable by Tenant and collectible by
Landlord as such.

exclusively as offices, and are kept reasonably in order by Tenant, and if to be

Dear Mr Newton,

RENT REVIEW 91 ST PAUL'S ROAD

You will recall that I wrote to your recently reference our intention at
Folgate Estates Limited to review the rent in respect of the premises you
occupy under a lease dated the 20th May 1988. I now propose that the rent will
be reviewed to the yearly sum of pounds 210,000 (Two hundred and ten thousand
pounds) with effect from the 25th March 1993.

Your attention is drawn to the revisions of the lease in the event that my
proposals are unacceptable to you.

I will be happy to meet with you to discuss this matter and other outstanding
issues between our respective companies.

Yours sincerely,
FOLGATE ESTATES LIMITED

Dear Louise

RE: UNIT 5, SECOND FLOOR UNIT 6

Further to our various discussions I confirm that Zambon have agreed in
principle to a variation of your lease for Unit 5 and 6 on the following terms:

l.       Synon relinquish the right to break their lease as provided for in the
         current lease contract, in March 1996.

2.       Synon indemnify Zambon against any costs incurred in the extension. As
         I explained I can only foresee this including legal costs of
         documentation.

3.       In return for the above Zambon will agree to an extension of your
         existing lease, to expire on 31st January 1998. Rental and all other
         terms will remain as per the existing agreement.

Please confirm your agreement to the above at which point I will instruct
solicitors.

Yours sincerely

                                  Your Ref:

Dear Mr. Bhalla,

RE: SYNON/ZAMBON

I refer to our telephone conversation of Monday this week.  Your company is in
possession of the Premises pursuant to an Agreement for Lease.  As I mentioned
I received various documents in relation to the completion of this matter which
require attention.  I enclose the following:-

1.       The engrossment of a Counterpart Underlease.  This should be sealed by
         your Company and witnessed where shown on page 21 and returned to me
         undated.  I have corrected the spelling of your Company's name in
         manuscript.

2.       The Counterpart Licence for Alteration.  This needs to be sealed on
         page 6 by the Sub-Tenant. You will note in this case and the case
         above that of course it will have to be witnessed by two Directors or
         the Director and the Company Secretary.

3.       Engrossment of the Licence to Underlet (somewhat modest engrossment
         but rather than delay it further I suggest we accept it).  This should
         be pleased sealed and witnessed where shown with a yellow sticker.
         Again I have corrected your corporate name.  Please date and return
         this to me at your earliest convenience.

If you have any questions or queries, or if I can help in any way, then please
do not hesitate to let me know.  There is one outstanding Licence for
Alterations, which I am pressing Danbuild's solicitors on.

I look forward to hearing further from you.

Yours Sincerely,

         consent; nor

2.2      underlet any part of the Premises save for a Permitted Part as defined
         in the Lease; nor

2.3      underlet the whole or a Permitted Part of the Premises at a rent less

         and effect which the Tenant's Guarantor now confirms.

The Contractor shall have the right in its sole discretion to determine which of

CONFIDENTIALITY

A. As part of the consideration required of the Contractor under this Agreement,
the Contractor and its employees agree that, except as necessary to carry out
the provisions of this Agreement and except as may be required by law, it shall

foregoing, information concerning any of the Client's price lists, marketing
lists, business strategies, innovations, trade secrets, or any other information

data of CGI Systems or its Client. The parties hereby stipulate that all such
information is confidential material and affects the successful conduct of the
business and the goodwill of CGI Systems or its Client.

B. The Contractor agrees not to copy, disclose, or use for its own purposes or

TAXES AND BENEFITS

Contractor has advised its employees, and any non CGI Systems subcontractors
("Contractor Personnel"), that they are not employees of CGI Systems or its
Client, or are they entitled to any benefits provided or rights guaranteed by
CGI Systems or its Client, or by operation of law, to their respective
employees, including but not limited to group insurance, liability insurance,
disability insurance, paid vacations, sick leave or other leave, retirement
plans, health plans, premium "overtime" pay, and the like. It is understood and
agreed that since the Contractor Personnel are not employees of CGI Systems, CGI
systems will make no deductions from fees paid to Contractor for any federal or
state taxes or FICA relating to Contractor Personnel, and CGI Systems or its
Client have no obligation to provide Worker's Compensation coverage for
Contractor Personnel or to make any premium "overtime" payments. It is agreed
that it is the Contractor's responsibility to provide Worker's Compensation and,
if applicable, pay any premium "overtime" rate for Contractor Personnel who work
on the project covered by this Agreement and to make required FICA, FUTA, income
tax withholding or other payments related to such Contractor Personnel. In the
event of any claims brought or threatened by any party against CGI Systems or
its Client relating to the status, acts or omissions of Contractor or Contractor
Personnel. Contractor and Contractor Personnel agrees to cooperate in all
reasonable respects, including to support the assertions of employment status
made in this Agreement.

INSURANCE

Contractor will obtain for itself and its Personnel before providing services,
at its own expense, comprehensive General Liability (GL) insurance coverage for
projects covered by this Agreement, for limits of liability not less than
$100,000 and will name CGI Systems as an Additional Insured, and hold CGI
systems harmless for any damages or expenses, including attorneys' fees,
incurred as a result of misconduct of Contractor or its Personnel involving CGI
Systems or its Client. COVENANT NOT TO COMPETE The contractor retains the right
to contract for similar services with other businesses or with individuals
subject to the following limitations:

(1) Contractor agrees that during the term of this Agreement or any extension
thereof, and for a period of (1) year after the termination of this Agreement,
the Contractor will not directly or indirectly or in any capacity, compete or
attempt to compete with CGI systems to provide computer programming or data
processing services similar to the services provided under the Statement of
Work (a) by soliciting or otherwise inducing the CGI Systems' Client referred to
in this Agreement to discontinue its relationship with CGI systems, or (b) in
any capacity, by performing or accepting an engagement to perform services of
the type being performed by the Contractor under the Statement of Work for the
client of CGI systems; and

(2) Contractor agrees that during the term of this Agreement or any extension
thereof, and for a period of (1) year after the termination of this Agreement,
the Contractor will not directly or indirectly or in any capacity, compete or
attempt to compete with CGI systems by inducing any personnel of CGI systems or
its Client to leave the service of CGI Systems or its Client.

The provisions of this non-competition clause shall be construed as an
agreement independent of any other provision contained herein and shall be
enforceable in both law and equity, including by temporary or permanent
restraining orders, notwithstanding the existence of any claim or cause of
action by the Contractor against CGI Systems or by CGI Systems against the
Contractor whether predicated on this Agreement or otherwise. This provision
survives termination of this Agreement.


                                       3
<PAGE>   5

If any provision of this Restrictive Covenant is held to be unenforceable
because of its scope, duration or area of its applicability, or otherwise, the
court making the determination will have the power to modify the scope,
duration or area, or all of them, and the provision will then apply in that
modified form.

NON-SOLICITATION

Each of the parties hereto agrees that, while performing Services under this
Agreement, and for a period of twelve (12) months following the termination of
this Agreement, neither party will, except with the other party's prior written
approval, solicit or offer employment to the other party's employees.

LIABILITY

The Contractor assumes and agrees to indemnify and save harmless CGI Systems
and its Client from any and all claims, expenses, damages, suits, costs, or
judgments whatsoever, whether groundless or otherwise, arising in whole or in
part out of any act or failure to act on the part of the Contractor,* and
provided such act or failure to act be within the scope of the Statement of
Work, unless such act or failure to act was at the specific direction of CGI
Systems or its Client.

The Contractor agrees to assume full liability for bodily injury, property
damage, fire, theft or collision claims arising out of the use of machinery,
equipment, material or vehicles provided by CGI Systems or its Client while in
the care, custody or control of the Contractor, its agents or employees unless
attributable to the negligence of CGI Systems or its Client.

The Contractor is responsible for the professional competence of the assigned
individuals and for their ability to perform the services to be provided by
them in a professional fashion.

Neither party shall be liable for general, special or consequential damages.

TERMINATION

No Statement of Work attached hereto may be terminated by either party prior to
the completion of the project described in the Statement of Work, except in the
following cases:

a. CGI Systems shall have the right to terminate the Statement of Work
immediately for cause.

b. CGI Systems or the Contractor shall have the right to terminate the
Statement of Work without cause with 14 (fourteen) days notice.

PAYMENT FOR SERVICES

Payment for services for hours actually worked or deliverables developed will
be made in the corporate name of Contractor on the periodic basis or payment
schedule set forth in the Statement of Work. Payment to the Contractor will be
in accordance with the agreed-upon payment terms specified in the Statement of
Work and no other compensation in any form, including benefits, will be
provided by CGI Systems or anyone else. Contractor shall maintain records of
hours during which services have been performed, and submit to CGI Systems
those records along with Contractor's invoice for the amount due to Contractor
for the hours worked or work delivered. CGI Systems' policy is to pay within
fifteen (15) business days of receipt of invoice and appropriate documentation.
Due to holidays and other factors, some delays in the Accounts

that, if any one provision or clause conflicts with existing or future
applicable law, or may not be given full effect because of such law, this shall
not affect any other provision of the Agreement which can be given effect
without the conflicting provision or clause. To the extent that there may be
any conflict between the terms of this Agreement and the Statement of Work,
this Agreement shall take precedence. Contractor represents that Contractor
has read and understands the terms of this Agreement, has had an opportunity
to ask any questions and to seek the assistance of legal counsel regarding
these terms, and is not relying upon any advice from CGI Systems in this regard.

This Agreement shall be governed by the laws of the State of Delaware,
regardless of where Contractors' work is performed, and any litigation shall
be brought in the state or federal courts of the State of Delaware.

         2.      LOAN AND TERMS OF PAYMENT

                 2.1      Revolving Advances.  Subject to the terms and
conditions of this Agreement, Bank agrees to make cash advances ("Advances") to
Borrowers in an aggregate amount not to exceed the lesser of the Committed Line
or the Borrowing Base, provided that Borrowers may not at any time have
outstanding Advances in excess of Two Million Five Hundred Thousand Dollars
($2,500,000) until the first date on which Parent reports in the consolidated
financial statements delivered under Section 6.3 that Parent and its
Subsidiaries have achieved an aggregate Modified Cash Flow of not less than One
Million Dollars ($1,000,000) at any time during Borrowers' fiscal year 1994.
For purposes of this Agreement "Borrowing Base" shall mean an amount equal to
seventy percent (70%) of Eligible Accounts.

         To evidence the Advances, Borrowers shall execute and deliver to Bank
on the date hereof the Revolving Note.

         Whenever Borrowers desire an Advance, Borrowers will notify Bank by
facsimile transmission or telephone no later than 11:00 a.m. California time,
one Business Day before the day the Advance is to be made. Each such
notification shall be promptly confirmed by a Borrowing Certificate in
substantially the form of Exhibit C hereto. Bank shall be entitled to rely on
any such telephonic notice given by any person who Bank reasonably believes to
be a Responsible Officer of either Borrower, and Borrowers shall indemnify and
hold Bank harmless for any damage or loss suffered by Bank as a result of such
reliance.

         Bank is authorized to make Advances under this Agreement, based upon
instructions received from a Responsible Officer of either Borrower, or without
instructions if in Bank's discretion such Advances are necessary to meet
Obligations which have become due and remain unpaid. Bank will credit the amount
of Advances made under this Section 2.1 to a Borrower's loan account. Amounts
borrowed pursuant to this Section 2.1 may be repaid and reborrowed at any time
during the term of this Agreement so long as no Event of Default has occurred
and is continuing.

         The Revolving Facility shall terminate on the Maturity Date, at which
time all amounts advanced under this Section 2.1 shall be immediately due and
payable.

                 2.2      Overadvances.  If, at any time or for any reason, the
amount of Obligations owed by Borrowers to Bank pursuant to Section 2.1 of this
Agreement is greater than the lesser of (i) the Committed Line or (ii) the
Borrowing Base, Borrower shall immediately pay to Bank, in cash, the amount of
such excess.

                 2.3      Accounts Collection.  Borrowers shall enter into a
lockbox agreement with Bank, pursuant to which all funds received by each
Borrower from any source shall immediately be deposited.  Borrower shall direct
all account debtors to mail or deliver all checks or other forms of payment for
amounts owing to Borrower in the ordinary course of Borrower's business to such
lockbox designated by Bank.  Borrower shall hold in trust as collateral for
Bank all amounts that Borrower receives despite the directions to make payments
to such lockbox, and immediately deliver such payments to Bank in their
original form as received from the account debtor, with proper endorsements for
deposit into an account held by Bank.  Bank shall have a security interest in
all such proceeds, but will not exercise any rights against such proceeds
except upon the occurrence and during the continuance of an Event of Default.

                 2.4     Interest Rates, Payments, and Calculations.

                         (a)     Interest Rate.  Except as set forth in
Section 2.4(b), any Advances evidenced by the Note shall bear interest, on the
average Daily Balance, at a rate equal to two (2.0)


                                       9
<PAGE>   14
percentage points above the Prime Rate; provided that the rate shall be the
Prime Rate plus one and one quarter (1.25) percentage points above the Prime
Rate from and after the first date on which Parent reports in the financial
statements delivered under Section 6.3 that Borrowers have achieved an
aggregate Modified Cash Flow of not less than Two Hundred Fifty Thousand
Dollars ($250,000) at any time during Borrowers' fiscal year 1994.

                          (b)     Past-Due Rate.  If all or a portion of the
principal amount of any of the Advances made hereunder or any interest accrued
thereon or any Bank Expenses shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), then any such overdue amounts shall
bear interest at a rate per annum which is four (4) percentage points above the
rate otherwise then applicable.

                          (c)     Payments.  Interest hereunder shall be due
and payable on the last Business Day of each calendar month during the term
hereof.  Bank shall, at its option, charge such interest, all Bank Expenses,
and all Periodic Payments against either Borrower's loan account or against the
Committed Line, in which case those amounts shall thereafter accrue interest at
the rate then applicable hereunder.  Each Borrower authorizes Bank
automatically to deduct from such Borrower's account or accounts with Bank the
amount of any payment due hereunder.

                          (d)     Computation.  In the event the Prime Rate is
changed from time to time hereafter, the applicable rate of interest hereunder
shall be increased or decreased effective as of 12:01 a.m. on the day the Prime
Rate is changed, by an amount equal to such change in the Prime Rate.  All
interest chargeable under the Loan Documents shall be computed on the basis of
a three hundred sixty (360) day year for the actual number of days elapsed.

                 2.5      Crediting Payments.  The receipt by Bank of any wire
transfer of funds, check, or other item of payment shall be immediately applied
to conditionally reduce Obligations, but shall not be considered a payment on
account unless such payment is of immediately available federal funds and is
made to the appropriate deposit account of Bank or unless and until such check
or other item of payment is honored when presented for payment.
Notwithstanding anything to the contrary contained herein, any payment (other
than a wire transfer of immediately available funds) received by Bank after
11:00 a.m. California time shall be deemed to have been received by Bank as of
the opening of business on the immediately following Business Day.

                 2.6      Fees.  Borrowers shall pay to Bank the following:

                          (a)     Facility Fee.  Upon the date hereof, a
nonrefundable Commitment Fee equal to Fifteen Thousand Dollars ($15,000)
(Borrower having previously paid to Bank $15,000 constituting a partial payment
of the Commitment Fee), which shall be due upon the date of this Agreement and
shall be fully earned and nonrefundable;

                          (b)     Financial Examination and Appraisal Fees.
Bank's customary fees and out-of-pocket expenses for Bank's audits of either
Borrower's Accounts and Inventory, and for each appraisal of Collateral and
financial analysis and examination of such Borrower performed from time to time
by Bank or its agents (not to exceed $1,000 per audit); and

                          (c)     Bank Expenses.  Upon the date hereof, all
Bank Expenses incurred through the date hereof, including reasonable attorneys'
fees (not to exceed $5,000) and expenses.

                 2.7      Additional Costs.  In case any law, regulation,
treaty or official directive or the interpretation or application thereof by
any court of any governmental authority charged with the administration thereof
or the compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law):



                                       10
<PAGE>   15
                          (a)     subjects Bank to any tax with respect to
payments of principal or interest or any other amounts payable hereunder by
Borrower or otherwise with respect to the transactions contemplated hereby
(except for taxes on the overall net income of Bank imposed by the United
States of America or any political subdivision thereof); or

                          (b)     imposes, modifies or deems applicable any
deposit insurance, reserve, special deposit or similar requirement against
assets held by, or deposits in or for the account of, or loans by, Bank; or

                          (c)     imposes upon Bank any other condition with
respect to their performance under this Agreement, and the result of any of the
foregoing is to increase the cost to Bank, reduce the income receivable by Bank
or impose any expense upon Bank with respect to any loans, Bank shall notify
Borrowers thereof.  Borrowers agree to pay to Bank the amount of such increase
in cost, reduction in income or additional expense as and when such cost,
reduction or expense is incurred or determined, upon presentation by Bank of a
statement in the amount and setting forth Bank's calculation thereof, all in
reasonable detail, which statement shall be deemed true and correct absent
manifest error; provided, however, that the Borrowers shall not be liable for
any such amount attributable to any period prior to the date one hundred eighty
(180) days prior to the date of such certificate.

                 2.8      Term.  This Agreement shall become effective upon the
date hereof and shall continue in full force and effect for a term ending on
the Maturity Date.  Notwithstanding the foregoing, Bank shall have the right to
terminate its obligation to make Advances under this Agreement immediately and
without notice upon the occurrence and during the continuance of an Event of
Default.

         3.      CONDITIONS OF LOANS

                 3.1      Conditions Precedent to Initial Loan.  The obligation

         4.      CREATION OF SECURITY INTEREST

                 4.1      Grant of Security Interest.  Borrowers grant to Bank
a continuing security interest in all presently existing and hereafter acquired
or arising Collateral in order to secure prompt repayment of any and all
Obligations and in order to secure prompt performance by Borrowers of each of
their respective covenants and duties under the Loan Documents.  Except as set
forth in the Schedule, such security interest constitutes a valid, first
priority security interest in the presently existing Collateral (other than
Excluded Intellectual Property), and will constitute a valid, first priority
security interest in Collateral acquired after the date hereof (other than
Excluded Intellectual Property).

                 4.2      Delivery of Additional Documentation Required.
Borrowers shall from time to time execute and deliver to Bank, at the request

check, test, and appraise the Collateral in order to verify such Borrower's
financial condition or the amount, condition of, or any other matter relating
to, the Collateral.

         5.      REPRESENTATIONS AND WARRANTIES

                 Each Borrower represents and warrants as follows:

                 5.1      Due Organization and Qualification.  Such Borrower is
a corporation duly existing and in good standing under the laws of its state of
incorporation and qualified and licensed to do business in, and is in good
standing in, any state in which the conduct of its business or its ownership of
property requires that it be so qualified, except for such states as to which
any failure so to qualify is not reasonably likely to have a Material Adverse
Effect on such Borrower.

                 5.2      Due Authorization: No Conflict.  The execution,
delivery, and performance of the Loan Documents are within such Borrower's
powers, have been duly authorized, and are not in conflict with nor constitute
a breach of any provision contained in such Borrower's Articles or Certificate
of Incorporation as appropriate, or Bylaws, nor will they constitute an event
of default under any material agreement to which such Borrower is a party or by
which such Borrower is bound. Such Borrower is not in default under any
agreement to which it is a party or by which it is bound, which default is
reasonably likely to have a Material Adverse Effect on such Borrower.

                 5.3      No Prior Encumbrances.  Such Borrower has good and
indefeasible title to the Collateral, free and clear of Liens, except for
Permitted Liens.  Except as disclosed in the Schedule, such Borrower has not
acquired any part of the Collateral from an assignor outside the ordinary
course of such assignor's business.

                                       12
<PAGE>   17
                 5.4      Bona Fide Accounts.  The Eligible Accounts are bona
fide existing obligations created by the sale and delivery of Inventory or the
rendition of services to account debtors in the ordinary course of such
Borrower's business, unconditionally owed to such Borrower without defenses,
disputes, offsets, counterclaims, or rights of return or cancellation.  The
property giving rise to such Eligible Accounts has been delivered to the
account debtor or to the account debtor's agent for immediate shipment to and
unconditional acceptance by the account debtor.  Such Borrower has not received
notice of actual or imminent Insolvency Proceedings of any account debtor at
the time an account due from such account debtor is included in any Borrowing
Base Certificate as an Eligible Account

                 5.5      Merchantable Inventory.  All Inventory is in all
material respects of good and marketable quality.

                 5.6      Name; Location of Chief Executive Office.  Except as
disclosed in the Schedule, such Borrower has not done business under any name
other than that specified on the signature page hereof.  The chief executive
office of such Borrower is located at the address indicated in Section 11
hereof.

                 5.7      Litigation.  Except as set forth in the Schedule,
there are no actions or proceedings pending by or against such Borrower before
any court or administrative agency in which an adverse decision can be
reasonably expected to have a Material Adverse Effect on such Borrower or the
Collateral.  Except as set forth in the Schedule, such Borrower does not have
knowledge of any such pending or threatened actions or proceedings.

                 5.8      No Material Adverse Change.  All financial statements
relating to such Borrower (consolidated, in the case of Parent) that have been
delivered by such Borrower to Bank fairly present in all material respects such
Borrower's financial condition as of the date thereof and Borrower's results of
operations for the period then ended.  There has not been a material adverse
change in the financial condition of such Borrower since the date of the most
recent of such financial statements submitted to Bank.  Since such date, there
has not occurred a material adverse change in Borrower's business, a material
impairment of the prospect of repayment of any portion of the Obligations owing
to Bank or a material impairment of the value of priority of Bank's security
interest in the Collateral.

                 5.9      Solvency.  Such Borrower is solvent and able to pay
its debts (including trade debts) as they mature.

                 5.10     Regulatory Compliance.  Such Borrower has met the
minimum funding requirements of ERISA with respect to any employee benefit plans
subject to ERISA. No event has occurred resulting from Borrower's failure to
comply with ERISA that is reasonably likely to result in such Borrower's
incurring any liability that is reasonably likely to have a Material Adverse
Effect on such Borrower.  Such Borrower is not an "investment company" or a
company "controlled" by an "investment company" within the meaning of the
Investment Company Act of 1940.  Such Borrower is not engaged principally, or as
one of the important activities, in the business of extending credit for the
purpose of purchasing or carrying margin stock (within the meaning of
Regulations G, T and U of the Board of Governors of the Federal Reserve System).
Such Borrower has complied with all the provisions of the Federal Fair Labor
Standards Act.

                 5.11     Environmental Condition.  None of such Borrower's
properties or assets has ever been used by such Borrower or, to the best of
such Borrower's knowledge, by previous owners or operators, in the disposal of,
or to produce, store, handle, treat, release, or transport, any hazardous waste
or hazardous substance other than in accordance with applicable law; to the
best of such Borrower's knowledge, none of such Borrower's properties or assets
has ever been designated or identified in any manner pursuant to any
environmental protection statute as a hazardous waste or hazardous substance
disposal site, or a candidate for closure pursuant to any environmental
protection statute; no lien arising under any environmental protection statute
has attached to any revenues or to any real or personal property owned by such
Borrower, and such Borrower has not received a summons, citation, notice, or


                                       13
<PAGE>   18
directive from the Environmental Protection Agency or any other federal or
state governmental agency concerning any action or omission by Borrower
resulting in the releasing, or otherwise disposing of hazardous waste or
hazardous substances into the environment.

                 5.12     Taxes.  Such Borrower has filed or caused to be filed
all material tax returns required to be filed, and has paid, or has made
adequate provision for the payment of, all taxes reflected therein.

                 5.13     Subsidiaries.  Such Borrower does not own any stock,
partnership interest or other equity securities of any entity, except for
Permitted Investments,

                 5.14     Government Consents.  Such Borrower has obtained all
consents, approvals and authorizations of, made all declarations or filings
with, and given all notices to, all governmental authorities that are necessary
for the continued operation of such Borrower's business as currently conducted
except where the failure to do so is not likely to have a Material Adverse
Effect.

                 5.15     Full Disclosure.  The representations, warranties and
other statements included in the documents, certificates and written statements
furnished by each Borrower to Bank prior to or as of the date of this Agreement
for use in connection with the transactions contemplated by this Agreement,
taken as a whole, do not contain any untrue statement of a material fact or
omit to state a material fact (known to such Borrower, in the case of any
document not furnished by it) necessary in order to make the statements
contained herein or therein not misleading (it being recognized by Bank that
the projections and forecasts provided by each Borrower are not to be viewed as
facts and that actual results during the period or periods covered by any such
projections and forecasts may differ from the projected or forecasted results).

         6.      AFFIRMATIVE COVENANTS

                 Each Borrower covenants and agrees that, until payment in full 
of the Obligations, such Borrower shall do or cause to be done all of the
following:

                 6.1      Good Standing.  Such Borrower shall maintain its
corporate existence and its good standing in its jurisdiction of incorporation
and maintain qualification in each jurisdiction in which the failure to so
qualify is reasonably likely to have a Material Adverse Effect on such Borrower.
Such Borrower shall maintain in force all licenses, approvals and agreements,
the loss of which is reasonably likely to have a Material Adverse Effect on such
Borrower.

                 6.2      Government Compliance.  Such Borrower shall comply
with all statutes, laws, ordinances and government rules and regulations to
which it is subject, noncompliance with which is reasonably likely to have a
Material Adverse Effect on such Borrower.

                 6.3      Financial Statements, Reports, Certificates.  Such
Borrower shall deliver to Bank:  (a)     as soon as available, but in any event

sheet, income statement and cash flow statement covering such Borrower's
consolidated operations during such period, certified by an officer of such
Borrower reasonably acceptable to Bank; (b) as soon as available, but in any
event within thirty (30) days after the end of each month, company prepared
consolidating financial statements including a schedule of intercompany charges
for each of such Borrower's foreign subsidiary; (c) as soon as available, but
in any event within ninety (90) days after the end of such Borrower's fiscal
year, audited financial statements of Borrower on a consolidated basis prepared
in accordance with GAAP, consistently applied, together with an unqualified
opinion on such financial statements of an independent certified public
accounting firm reasonably acceptable to Bank (which audits for the years 1992
and 1993 shall contain no material changes from preliminary draft financial
statements or company prepared financial statements delivered to Bank), and (at
the time of filing with the appropriate tax authorities) the federal tax
returns of Borrower, (d) promptly upon


                                       14
<PAGE>   19
becoming available, copies of all statements, reports and notices sent or made
available generally by such Borrower to its security holders or to any holders
of Subordinated Debt; (e) promptly upon receipt of notice thereof, a report of
any legal actions pending or threatened against such Borrower which may result
in damages to such Borrower in excess of $250,000; and (f) such budgets, sales
projections, operating plans or other financial information as Bank may
reasonably request from time to time.

         Within thirty (30) days of the last day of each month, Borrowers shall
deliver to Bank a borrowing base certificate signed by an officer of Parent on
behalf of Borrowers in substantially the form of Exhibit D hereto, together
with aged listings of accounts receivable and accounts payable; provided that,
for any period in which any Advances are outstanding under this Agreement,
Borrowers shall deliver such borrowing base certificate semi-monthly, within
(ten) 10 days of the end of each two-week period.

         Borrowers shall deliver to Bank with the monthly financial statements
a compliance certificate signed by a Responsible Officer of Parent in
substantially the form of Exhibit
Exhibit E hereto.

         Bank shall have a right from time to time thereafter to audit either
Borrower's Accounts at such Borrower's expense, provided that such audits will
be conducted no more often than three (3) times per year unless an Event of
Default has occurred and is continuing.

                 6.4      Returns.  Returns and allowances, if any, as between
such Borrower and its account debtors shall be on the same basis and in
accordance with the usual customary practices of such Borrower, as they exist
at the time of the execution and delivery of this Agreement.  Such Borrower
shall promptly notify Bank of all returns and recoveries and of all disputes
and claims, where the return, recovery, dispute or claim involves more than Two
Hundred Thousand Dollars ($200,000).

                 6.5      Taxes.  Such Borrower shall make due and timely
payment or deposit of all material federal, state, and local taxes,
assessments, or contributions required of it by law, and will execute and
deliver to Bank, on demand, appropriate certificates attesting to the payment
or deposit thereof; and such Borrower will make timely payment or deposit of
all material tax payments and withholding taxes required of it by applicable
laws, including, but not limited to, those laws concerning F.I.C.A., F.U.T.A.,
state disability, and local, state, and federal income taxes, and will,
upon request, furnish Bank with proof satisfactory to Bank indicating that such
Borrower has made such payments or deposits; provided that Borrower need not
make any payment if the amount or validity of such payment is contested in good
faith by appropriate proceedings and is adequately reserved against (to the
extent required by GAAP) by such Borrower.

                 6.6      Insurance.

                          (a)     Such Borrower, at its expense, shall keep the
Collateral insured against loss or damage by fire, theft, explosion,
sprinklers, and all other hazards and risks, and in such amounts, as ordinarily
insured against by other owners in similar businesses conducted in the
locations where Borrower's business is conducted on the date hereof. Each
Borrower shall also maintain insurance relating to Borrower's ownership and use
of the Collateral in amounts and of a type that are customary to businesses
similar to Borrower's.

                          (b)     All such policies of insurance shall be in
such form, with such companies, and in such amounts as reasonably satisfactory
to Bank.  All such policies of property insurance shall contain a lender's loss
payable endorsement, in a form satisfactory to Bank, showing Bank as an
additional loss payee thereof, and all liability insurance policies shall show
the Bank as an additional insured, and shall specify that the insurer must give
at least twenty (20) days notice to Bank before canceling its policy for any
reason.  Borrower shall deliver to Bank certified copies of such policies of
insurance and evidence of the payments of all premiums therefor.  All proceeds
payable under any such policy shall, at the option of Bank, be payable to Bank
to be applied on account of the Obligations.

Bank with an account balance not to exceed $250,000.

                 6.8      Quick Ratio.  Parent shall maintain, on a
consolidated basis with its Subsidiaries, as of the last day of each calendar
month, a ratio of Quick Assets to Current Liabilities (excluding deferred

from the Closing Date until August 31, 1994; 1.10 to 1.0 thereafter until
September 30, 1994, and 1.25 to 1.0 thereafter.

                 6.9      Additional Quick Ratio.  Borrowers shall maintain,
for Borrowers only and not on a consolidated basis with any other entity, as of
the last day of each calendar month, a ratio of Quick Assets (of Borrowers

relating to maintenance income) of at least 1.05 to 1.00 for the period from
the Closing Date until August 31, 1994; 1.10 to 1.0 thereafter until September
30, 1994, and 1.25 to 1.0 thereafter.

                 6.10     Debt-Net Worth Ratio.  Parent shall maintain, on a
consolidated basis with its Subsidiaries, as of the last day of each calendar
month, a ratio of Total Liabilities less Subordinated Debt (and excluding

1994, 3.00 to 1.00 and (ii) thereafter, 2.25 to 1.00.

                 6.11     Profitability.  Parent shall, on a consolidated basis

                 6.12     Registration of Intellectual Property Rights.

registered) with the United States Patent and Trademark Office or the United
States Copyright Office, as applicable, those intellectual property rights 
listed on Exhibits A, B and C to the Intellectual Property Security Agreement,
dated the date hereof, delivered to Bank by Borrower, as soon as is practicable.
Borrowers shall register or cause to be registered with the United States Patent
and Trademark Office or the United States Copyright Office, as applicable, those
additional United States material registrable intellectual property rights
developed or acquired by Borrower from time to time; provided, however, that
Borrower shall only be required to register (i) copyrights for source (codes and

perfect Bank's security interest in such additional intellectual property
rights.

                 6.13     Further Assurances. At any time and from time to time
each Borrower shall execute and deliver such further instruments and take such
further action as may reasonably be requested by Bank to effect the purposes of
this Agreement.

         7.      NEGATIVE COVENANTS

         Each Borrower covenants and agrees that, so long as any credit
hereunder shall be available and until payment in full of the outstanding
Obligations, neither Borrower will do, or permit to be done, any of the
following without the prior written consent of Bank:


                                       16
<PAGE>   21
                 7.1      Dispositions.  Convey, sell, lease, transfer or
otherwise dispose of (collectively, a "Transfer"), or permit any Subsidiary to

7.1 not exceeding $100,000 in any fiscal year.

                 7.2      Change in Business.  Neither Parent nor any of its
Subsidiaries shall engage in any business other than the businesses currently
engaged in by Parent and its Subsidiaries and any business substantially
similar or related thereto (or incidental thereto).  Borrowers will not,
without thirty (30) days prior written notification to Bank, relocate their
chief executive offices.

                 7.3      Mergers or Acquisitions.  Merge or consolidate, or

among Borrowers and the Non-Borrower Subsidiaries in which a Borrower is the
surviving entity or among the Non-Borrower Subsidiaries or to purchases of
inventory, equipment or intellectual property rights in any transaction valued

liable with respect to any Indebtedness other than Permitted Indebtedness.

                 7.5      Encumbrances.  Create, incur, assume or suffer to
exist any Lien with respect to any of its property, or assign or otherwise
convey any right to receive income, including the sale of any Accounts, or
permit any of the Subsidiaries so to do, except for Permitted Liens.

                 7.6      Distributions. Pay any dividends or make any other
distribution or payment on account of or in redemption, retirement or purchase
of any capital stock, provided that (1) a Borrower may declare and make any

Borrower may convert any of its convertible securities into other securities
pursuant to the terms of such convertible securities or otherwise in exchange
therefor, (3) Parent may repurchase shares of its Series E Preferred Stock

before and after such repurchase and Parent has given Bank copies of all
notices issued in connection with such repurchase at the same time as Parent
has given the notices to International Business Machines Corporation, and (4) a
Borrower may redeem or repurchase its securities in an amount in any fiscal
year not exceeding $150,000 in connection with any agreement between Parent or
the Subsidiaries and any officer, director, employee or consultant of Parent or

enter into or permit to exist any material transaction with any Affiliate of a
Borrower except for transactions that are in the ordinary course of such
Borrower's business, upon fair and reasonable terms that are no less favorable
to such Borrower than would be obtained in an arm's length transaction with a
nonaffiliated Person and except for

                                       17
<PAGE>   22
transactions with the Non-Borrower Subsidiaries that are upon fair and
reasonable terms and transactions constituting Permitted Investments.

                 7.9      Subordinated Debt.  Make any payment in respect of
any Subordinated Debt, or permit any of the Subsidiaries to make any such

warehouseman, or similar party unless Bank has received a pledge of the
warehouse receipt covering such Inventory.  Except for Inventory sold in the
ordinary course of business and except for such other locations as Bank may
approve in writing, Borrowers shall keep the Inventory only at the location set
forth in Section 11 hereof and such other locations of which the Borrowers give

financing statement where needed to perfect Bank's security interest.

                 7.11     Compliance.  Become an "investment company" or be
controlled by an "investment company",' within the meaning of the Investment

such purpose; fail to meet the minimum funding requirements of ERISA, permit a
Reportable Event or Prohibited Transaction, as defined in ERISA, to occur, fail
to comply with the Federal Fair Labor Standards Act or violate any law or
regulation, which violation is reasonably likely to have a Material Adverse
Effect or a material adverse effect on the Collateral or the priority of Bank's
lien on the Collateral, or permit any of its Subsidiaries to do any of the
foregoing.

         8.      EVENTS OF DEFAULT

                 Any one or more of the following events shall constitute an
Event of Default by Borrowers under this Agreement

                 8.1      Payment Default.  If Borrowers fail to pay the
principal of, or any interest on, any Advances when due and payable, or any
portion of any other Obligations not constituting such principal or interest,
including without limitation Bank Expenses, within thirty (30) days of receipt
by Borrower of an invoice therefor.

                 8.2      Covenant Default.  If either Borrower or Borrowers,
as applicable, fail to perform any obligation under Sections 6.6, 6.7, 6.8,
6.9, 6.10 or 6.11, or violate any of the covenants contained in Article 7
(other than 7.5, 7.7, and 7.10) of this Agreement or fail or neglect to
perform, keep, or observe any other material term, provision, condition,
covenant, or agreement contained in this Agreement, in any of the Loan
Documents, or in any other present or future agreement between Borrower and
Bank and as to any default under such other term, provision, condition,
covenant or agreement that can be cured, have failed to cure such default
within ten (10) days after the Borrower receives notice thereof or any
Responsible Officer of Borrower become aware thereof (provided that no Advances
will be required to be made during such cure period); provided, however, that
if the default cannot by its nature be cured within the ten (10) day period or
cannot after diligent attempts by Borrower be cured within such ten (10) day
period, and such default is likely to be cured within a reasonable time (which
shall not in any case exceed thirty (30) days), then Borrower shall have an
additional reasonable period to attempt to cure such default, and within such
reasonable time period the failure to have cured such default shall not be
deemed an Event of Default; provided further that no such additional reasonable
time shall be available (i) to care a failure to provide the statements,
reports and other documents and information to be delivered under Section 6.3
or (ii) to cure a default if a default of a similar nature or under the same
provision hereof occurred within six (6) months of such later default;





                                       18
<PAGE>   23
                 8.3      Attachment. If any material portion of either
Borrower's assets is attached, seized, subjected to a writ or distress warrant,
or is levied upon, or comes into the possession of any trustee, receiver or
person acting in a similar capacity and such attachment, seizure, writ or
distress warrant or levy has not been removed, discharged or rescinded within
thirty (30) consecutive days, or if either Borrower is enjoined, restrained, or
in any way prevented by court order from continuing to conduct all or any
material part of its business affairs, or if a judgment or other claim becomes
a lien or encumbrance upon any material portion of either Borrower's assets, or
if a notice of lien, levy, or assessment is filed of record with respect to any
of either Borrower's assets by the United States Government, or any department,
agency, or instrumentality thereof, or by any state, county, municipal, or
governmental agency, and the same is not paid within thirty (30) days after
such Borrower receives notice thereof, provided that none of the foregoing
shall constitute an Event of Default where such action or event is stayed or an
adequate bond has been posted pending a good faith contesting by such Borrower
(provided that no Advances will be made during such cure period);

                 8.4      Insolvency.  If an Insolvency Proceeding is commenced
by a Borrower, or if an Insolvency Proceeding is commenced against a Borrower
and is not dismissed or stayed within twenty (20) consecutive days (provided
that, except as Bank may determine in its sole and absolute discretion, no
Advances will be made prior to the dismissal of such Insolvency Proceeding);

                 8.5      Other Agreements.  If there is a default in any
agreement to which a Borrower is a party with a third party or parties or by
which a Borrower is otherwise bound resulting in a right by such third party or
parties, whether or not exercised, to accelerate the maturity of any
Indebtedness in an amount in excess of Five Hundred Thousand Dollars ($500,000)
or which would be reasonably likely to have a Material Adverse Effect;

                 8.6      Subordinated Debt. If a Borrower makes any payment on
account of Subordinated Debt, except to the extent such payment is allowed
under any subordination agreement entered into with Bank;

                 8.7      Judgments.  If a final judgment or judgments for the
payment of money in an amount, individually or in the aggregate, of at least One
Hundred Fifty Thousand Dollars ($150,000) shall be rendered against a Borrower
and shall remain unsatisfied and unstayed for a period of ten (10) days
(provided that, except as Bank may determine in its sole and absolute
discretion, no Advances will be made prior to the satisfaction or stay of such
judgment); or

                 8.8      Misrepresentations.  If any material
misrepresentation or material misstatement exists now or hereafter in any
warranty or representation made to Bank by any Responsible Officer of a
Borrower pursuant to this Agreement or any Loan Document.

         9.      BANK'S RIGHTS AND REMEDIES

                 9.1      Rights and Remedies.  Upon the occurrence and during
the continuance of an Event of Default, Bank may, at its election, without
notice of its election and without demand, except as required by law, do any
one or more of the following, all of which are authorized by Borrowers:

                          (a)     Declare all Obligations, whether evidenced by
this Agreement, by any of the other Loan Documents, or otherwise, immediately
due and payable (provided that upon the occurrence of an Event of Default
described in Section 8.5 all Obligations shall become immediately due and
payable without any action by Bank);

                          (b)     Cease advancing money or extending credit to
or for the benefit of Borrowers under this Agreement or under any other
agreement between either Borrower and Bank;


                                       19
<PAGE>   24
                          (c)     Settle or adjust disputes and claims directly
with account debtors for amounts, upon terms and in whatever order that Bank
reasonably considers advisable;

                          (d)     Without notice to or demand upon Borrower,
make such payments and do such acts as Bank considers necessary or reasonable
to protect its security interest in the Collateral.  Borrowers agree to
assemble the Collateral if Bank so requires, and to make the Collateral
available to Bank as Bank may designate.  Borrowers authorize Bank to enter the
premises where the Collateral is located, to take and maintain possession of
the Collateral, or any part of it, and to pay, purchase, contest, or compromise
any encumbrance, charge, or lien which in Bank's determination appears to be
prior or superior to its security interest and to pay all expenses incurred in
connection therewith.  With respect to any of either Borrower's owned premises,
each Borrower hereby grants Bank a license to enter into possession of such
premises and to occupy the same, without charge, for up to one hundred twenty
(120) days in order to exercise any of Bank's rights or remedies provided
herein, at law, in equity, or otherwise;

                          (e)     Without notice to either Borrower set off and
apply to the Obligations any and all (i) balances and deposits of either
Borrower held by Bank, or (ii) indebtedness at any time owing to or for the
credit or the account of either Borrower held by Bank;

                          (f)     Ship, reclaim, recover, store, finish,
maintain, repair, prepare for sale, advertise for sale, and sell (in the manner
provided for herein) the Collateral.  Bank is hereby granted a license or other
right, solely pursuant to the provisions of this Section 9.1, to use, without
charge, any Borrower's labels, patents, copyrights, rights of use of any name,
trade secrets, trade names, trademarks, service marks, and advertising matter,
or any property of a similar nature, as it pertains to the Collateral, in
completing production of, advertising for sale, and selling any Collateral and,
in connection with Bank's exercise of its rights under this Section 9.1, any
Borrower's rights under all licenses and all franchise agreements shall inure
to Bank's benefit;

                          (g)     Sell the Collateral at either a public or
private sale, or both, by way of one or more contracts or transactions, for
cash or on terms, in such manner and at such places (including any Borrower's
premises) as Bank determines is commercially reasonable;

                          (h)     Bank may credit bid and purchase at any public
sale; and

                          (i)     Any deficiency that exists after disposition
of the Collateral as provided above will be paid immediately by Borrowers.

                 9.2      Power of Attorney.  Effective only upon the
occurrence and during the continuance of an Event of Default, each Borrower
hereby irrevocably and appoints Bank (and any of Bank's designated officers, or
employees) as such Borrower's true and lawful attorney to: (a) send requests for
verification of Accounts or notify account debtors of Bank's security interest
in the Accounts; (b) endorse such Borrower's name on any checks or other forms
of payment or security that may come into Bank's possession; (c) sign the name
of such Borrower on any of the documents described in Section 4.5; (d) sign such
Borrower's name on any invoice or bill of lading relating to any Account, drafts
against account debtors, schedules and assignments of Accounts, verifications of
Accounts, and notices to account debtors; (e) make, settle, and adjust all
claims under and decisions with respect to such Borrower's policies of
insurance; and (f) settle and adjust disputes and claims respecting the accounts
directly with account debtors, for amounts and upon terms which Bank determines
to be reasonable. The appointment of Bank as such Borrower's attorney in fact,
and each and every one of Bank's rights and powers, being coupled with an
interest, is irrevocable until all of the Obligations have been fully repaid and
performed and Bank's obligation to provide advances hereunder is terminated.

                 9.3      Bank Expenses.  If any Borrower fails to pay any
amounts or furnish any required proof of payment due to third Persons, as
required under the terms of this Agreement, then Bank may do any or all of the
following: (a) make payment of the same or any part thereof, (b) set up such
reserves in

                                       20
<PAGE>   25
such Borrower's loan account as Bank deems necessary to protect Bank from the
exposure created by such failure; or (c) obtain and maintain insurance policies
of the type discussed in Section 6.6 of this Agreement, and take any action
with respect to such policies as Bank deems prudent.  Any amounts paid or
deposited by Bank shall constitute Bank Expenses, shall be immediately due and
payable, and shall bear interest at the then applicable rate hereinabove
provided, and shall be secured by the Collateral.  Any payments made by Bank
shall not constitute an agreement by Bank to make similar payments in the
future or a waiver by Bank of any Event of Default under this Agreement.

                 9.4      Remedies Cumulative.  Bank's rights and remedies
under this Agreement and the Loan Documents, shall be cumulative.  Bank shall
have all other rights and remedies not inconsistent herewith as provided under
the Code, by law, or in equity.  No exercise by Bank of one right or remedy
shall be deemed an election, and no waiver by Bank of any Event of Default on
Borrower's part shall be deemed a continuing waiver.  No delay by Bank shall
constitute a waiver, election, or acquiescence by it.

         10.     WAIVERS, INDEMNIFICATION

                 10.1     Demand: Protest.  Each Borrower waives demand,
protest, notice of protest, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees at any time held by Bank on which
such Borrower may in any way be liable.

                 10.2     Banks liability for Collateral. So long as Bank
complies with its obligations under Section 9207 of the Code and reasonable
banking practices, Bank shall not in any way or manner be liable or responsible
for: (a) the safekeeping of the Collateral; (b) any loss or damage thereto
occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other Person whomsoever.  All risk
of loss, damage or destruction of the Collateral shall be borne by Borrowers.

                 10.3     Indemnification.  Each Borrower shall defend,
indemnify and hold harmless Bank and its officers, employees, and agents against
(a) all obligations, demands, claims, and liabilities claimed or asserted by any
other party in connection with the transactions contemplated by this Agreement;
and (b) all losses or Bank Expenses in any way suffered, incurred, or paid by
Bank as a result of or in any way arising out of, from, to transactions between
Bank and such Borrower under this Agreement, or any other Loan Document
(including without limitation reasonable attorneys fees and expenses), except
for losses caused by Bank's gross negligence or willful misconduct.

                 10.4     Subrogation and Similar Rights.  Notwithstanding any
other provision of this Agreement or any other Loan Document, each Borrower
irrevocably waives all rights that it may have at law or in equity (including,
without limitation, any law subrogating the Borrower to the rights of Lender
under the Loan Documents) to seek contribution, indemnification, or any other
form of reimbursement from any other Borrower, or any other Person now or
hereafter primarily or secondarily liable for any of the Obligations, for any
payment made by the Borrower with respect to the Obligations in connection with
the Loan Documents or otherwise and all rights that it might have to benefit
from, or to participate in, any security for the Obligations as a result of any
payment made by the Borrower with respect to the Obligations in connection with
the Loan Documents or otherwise.  Any agreement providing for indemnification,
reimbursement or any other arrangement prohibited under this subsection (c)(i)
shall be null and void.  If any payment is made to a Borrower in contravention
of this subsection (c)(i), such Borrower shall hold such payment in trust for
Bank and such payment shall be promptly delivered to Bank for application to
the Obligations, whether matured or unmatured.

                 10.5     Waivers of Notice.  Each Borrower waives notice of
acceptance hereof, notice of the existence, creation or acquisition of any of
the Obligations; notice of the amount of the Obligations outstanding at any
time; notice of acceleration; notice of any adverse change in the financial
condition of any other Borrower or of any other fact that might increase the
Borrower's risk presentment for payment;


                                       21
<PAGE>   26
demand; protest and notice thereof as to any instrument; and all other notices
and demands to which the Borrower would otherwise be entitled.  Each Borrower
waives any defense arising from any defense of any other Borrower, or by reason
of the cessation from any cause whatsoever of the liability of any other
Borrower. Bank's failure at any time to require strict performance by any
Borrower of any provision of the Loan Documents shall not waive, alter or
diminish any right of Bank thereafter to demand strict compliance and
performance therewith.  Nothing contained herein shall prevent Bank from
foreclosing on the Lien of any deed of trust, mortgage or other security
instrument, or exercising any rights available thereunder, and the exercise of
any such rights shall not constitute a legal or equitable discharge of any
Borrower.  Each Borrower also waives any defense arising from any act or
omission of Bank that changes the scope of the Borrower's risks hereunder.
Each Borrower hereby waives any right to assert against Bank any defense (legal
or equitable), setoff, counterclaim, or claims that such Borrower individually
may now or hereafter have against another Borrower or any other Person liable
to Lender with respect to the Obligations in any manner or whatsoever.

                 10.6     Subrogation Defenses.  Each Borrower hereby waives
any defense based on impairment or destruction of its subrogation or other
rights against any other Borrower and waives all benefits which might otherwise
be available to it under California Civil Code Sections 2809, 2810, 2819, 2839,
2845, 2848, 2849, 2850, 2899, and 3433, as those statutory provisions are now
in effect and hereafter amended, and under any other similar statutes now and
hereafter in effect.

                 10.7     Right to Settle. Release.

                          (a)     The liability of Borrowers hereunder shall
not be diminished by (i) any agreement, understanding or representation that
any of the Obligations is or was to be guaranteed by another Person or secured
by other property, or (ii) any release or unenforceability, whether partial or
total, of rights, if any, which Lender may now or hereafter have against any
other Person, including another Borrower, or property with respect to any of
the Obligations.

                          (b)     Without notice to any Borrower and without
affecting the liability of any Borrower hereunder, Bank may (i) compromise,
settle, renew, extend the time for payment, change the manner or terms of
payment, discharge the performance of, decline to enforce, or release all or any
of the Obligations with respect to a Borrower, (ii) grant other indulgences to a
Borrower in respect of the Obligations, (iii) modify in any manner any documents
relating to the Obligations with respect to a Borrower, (iv) release, surrender
or exchange any deposits or other property securing the Obligations, whether
pledged by a Borrower or any other Person, or (v) compromise, settle, renew, or
extend the time for payment, discharge the performance of, decline to enforce,
or release all or any obligations of any guarantor, endorser or other Person who
is now or may hereafter be liable with respect to any of the Obligations.

                 10.8     Primary Obligation.  This Agreement is a primary and
original obligation of each Borrower and shall remain in effect notwithstanding
future changes in conditions, including any change of law or any invalidity or
irregularity in the creation or acquisition of any Obligations or in the
execution or delivery of any agreement between Bank and any Borrower.  Each
Borrower shall be liable for existing and future Obligations as fully as if all
of the Advance were advanced to the Borrower Bank may rely on any certificate
or representation made by any Borrower as made on behalf of, and binding on,
all Borrowers, including without limitation Borrowing Certificates, Borrowing
Base Certificates and Compliance Certificates.

                 10.9     Subordination.  All indebtedness of a Borrower now or
hereafter arising held by another Borrower is subordinated to the Obligations
and the Borrower holding the indebtedness shall take all actions reasonably
requested by Lender to effect, to enforce and to give notice of such
subordination.

<PAGE>   27
                 10.10    Enforcement of Rights.  Borrowers are jointly and
severally liable for the Obligations and Bank may proceed against one or more
of the Borrowers to enforce the Obligations without waiving its right to
proceed against any of the other Borrowers.

                 This Agreement shall be governed by, and construed in
accordance with, the internal laws of the State of California, without regard
to principles of conflicts of law.  Each of the Borrowers and Bank hereby
submits to the exclusive jurisdiction of the state and Federal courts located
in the County of Santa Clara, State of California.  Borrowers and Bank each
hereby waive their respective rights to a jury trial of any claim
or cause of action based upon or arising out of any of the Loan Documents or
any of the transactions contemplated therein, including contract claims, tort
claims, breach of duty claims, and all other common law or statutory claims.
Each party recognizes and agrees that the foregoing waiver constitutes a
material inducement for it to enter into this Agreement.  Each party represents
and warrants that it has reviewed this waiver with its legal counsel and that
it knowingly and voluntarily waives its jury trial rights following
consultation with legal counsel.

         13.     GENERAL PROVISIONS

                 13.1     Successors and Assigns.  This Agreement shall bind
and inure to the benefit ot the respective successors and permitted assigns of
each of the parties; provided, however, that neither this Agreement nor any
rights hereunder may be assigned by either Borrower without Bank's prior
written consent, which consent may be granted or withheld in Bank's sole
discretion.


                                       23
<PAGE>   28
                          (b)     Bank may sell, negotiate or grant
participations to other financial institutions in all or part of the
obligations of the Borrowers outstanding under the Loan Agreements, without
notice to or the approval of Borrowers; provided that any such sale,
negotiation or participation shall be in compliance with the applicable federal
and state securities laws and the other requirements of this Section 13.1.
Notwithstanding the sale, negotiation or grant of participations, Bank shall
remain solely responsible for the performance of its obligations under this
Agreement, Bank shall remain the holder of the Note for all purposes under this
Agreement and Borrowers shall continue to deal solely and directly with Bank in
connection with this Agreement and the other Loan Documents.

                          (c)     The grant of a participation interest shall
be on such terms as the Bank determines are appropriate, provided only that (1)
the holder of such a participation interest shall not have any of the rights of
Bank under this Agreement except, if the participation agreement so provides,
rights to demand the payment of costs of the type described in Section 2.7,
provided that the aggregate amount that the Borrowers shall be required to pay
under Section 2.7 with respect to any ratable share of the Committed Line or
any Advance (including amounts paid to participants) shall not exceed the
amount that Borrowers would have had to pay if no participation agreements had
been entered into, and (2) the consent of the holder of such a participation
interest shall not be required for amendments or waivers of provisions of the
Loan Agreement other than those which (i) increase the amount of the Committed
Line, (ii) extend the term of this Agreement, (iii) decrease the rate of
interest or the amount of any fee or any other amount payable to Bank under
this Agreement, (iv) reduce the principal amount payable under this Agreement,
or (v) extend the date fixed for the payment of principal or interest or any
other amount payable under this Agreement.

                          (d)     The Bank may assign, from time to time, all
or any portion of its pro rata share of the Committed Line and the Note to an
Affiliate of the Bank or, subject to the prior written approval of Borrower
(which approval will not be unreasonably withheld), to any other financial
institution; provided, that (i) the amount the Committed Line being assigned
pursuant to each such assignment shall in no event be less than $2,500,000 and
shall be an integral multiple of $500,000 and (ii) the parties to each such
assignment shall execute and deliver to Borrower an assignment agreement in a
form reasonably acceptable to each.  Upon such execution and delivery, from and
after the effective date specified in such assignment agreement (x) the
assignee thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such assignment
agreement, have the rights and obligations of a Bank hereunder and (y) Bank
shall, to the extent that rights and obligations hereunder have been assigned
by it pursuant to such assignment agreement, relinquish its rights and be
released from its obligations under this Agreement (other than pursuant to this 
Section 13.1(d)), and, in the case of an assignment agreement covering all or
the remaining portion of Bank's rights and obligations under this Agreement,
Bank shall cease to be a party hereto. In the event of as assignment hereunder,
the parties agree to amend this Agreement to the extent necessary to reflect the
mechanical changes which are necessary to document such assignment and which are
standard for a multi-bank credit facility. Each party shall bear its own
expenses (including without limitation attorneys' fees and costs) with respect
to such an amendment.

                 13.2     Time of Essence.  Time is of the essence for the
performance of all obligations set forth in this Agreement.

                 13.3     Severability of Provisions.  Each provision of this
Agreement shall be severable from every other provision of this Agreement for
the purpose of determining the legal enforceability of any specific provision.

cannot be changed or terminated orally.  All prior agreements, understandings,
representations, warranties, and negotiations between the parties hereto with
respect to the subject matter of this Agreement, if any, are merged into this
Agreement.

<PAGE>   29
                 13.5     Counterparts.  This Agreement may be executed in any 
number of counterparts and by different parties on separate counterparts, each
of which, when executed and delivered, shall be deemed to be an original, and
all of which, when taken together, shall constitute but one and the same
Agreement.

                 13.6     Survival.  All covenants, representations and
warranties made in this Agreement shall continue in full force and effect so
long as any Obligations remain outstanding.  The obligations of Borrowers to
indemnify Bank with respect to the expenses, damages, losses, costs and
liabilities described in Section 10.3 shall survive until all applicable
statute of limitations periods with respect to actions that may be brought
against Bank have run, provided that so long as the obligations set forth in
the first sentence of this Section 13.6 have been satisfied, and Bank shall
have no commitment to make any Advances or to make any other loans to
Borrowers, Bank shall release all security interests granted hereunder and
redeliver all Collateral held by it to Borrowers.

                 13.7     Confidentiality.  In handling any confidential
information of Borrowers Bank shall exercise the same degree of care that it
exercises with respect to its own proprietary information of the same types to
maintain the confidentiality of any non-public information thereby received or
received pursuant to this Agreement except that disclosure of such information
may be made (i) to the subsidiaries or affiliates of Bank in connection with
their present or prospective business relations with Borrower, (ii) to
prospective transferees or purchasers of any interest in the Advances, provided
that they have entered into a comparable confidentiality agreement in favor of
Borrowers and have delivered a copy to Borrowers, (iii) as required by law,
regulations, rule or order, subpoena, judicial order or similar order, provided
that Borrowers are notified and given an opportunity to seek a protective
order, and (iv) as may be required in connection with the examination, audit or
similar investigation of Bank.  Notwithstanding any provision of this Agreement
to the contrary, prior to the occurrence of an Event of Default neither
Borrower nor any of its Subsidiaries will be required to disclose, permit the
inspection, examination, copying or making extracts of, or discussions of; any
document, information or other matter that (i) constitutes non-financial trade
secrets or non-financial proprietary information (provided that the terms of
agreements that generate Accounts shall not be deemed to be "non-financial
trade secrets or proprietary information"), or (ii) in respect to which
disclosure to Bank (or designated representative) is then prohibited by (a)
law, or (b) an agreement binding upon Borrowers or any Subsidiary that was not
entered into by Borrowers or such Subsidiary for the primary purpose of
concealing information from Bank.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed as of the date first above written.

$4,000,000                                               Santa Clara, California
                                                                  March___, 1994
                                                                  

         FOR VALUE RECEIVED, the undersigned, Synon Corporation and Synon, Inc.
(the "Borrowers"), jointly and severally promise to pay to the order of Silicon
Valley Bank ("Bank"), at such place as the holder hereof may designate, in
lawful money of the United States of America, the aggregate unpaid principal
amount of all advances ("Advances") made by Bank to Borrowers under the terms of
the Loan Agreement (as defined below) up to a maximum principal amount of Four
Million Dollars ($4,000,000). Borrowers shall also pay interest on the aggregate
unpaid principal amount of such Advances at the rates and in accordance with the
terms of the Loan and Security Agreement between Borrowers and Bank of even date
herewith, as amended from time to time (the "Loan Agreement") on the last
Business Day of each month after an Advance has been made. The entire principal
amount and all accrued interest shall be due and payable on April 30, 1995.

         Borrowers irrevocably waive after the occurrence and during the
continuance of an Event of Default the right to direct the application of any
and all payments at any time hereafter received by Bank from or on behalf of
Borrowers, and each Borrower irrevocably agrees that Bank shall have the
continuing exclusive right to apply any and all such payments against the then
due and owing obligations of Borrowers as Bank may deem advisable. In the
absence of a specific determination by Bank with respect thereto, all payments
shall be applied in the following order: (a) then due and payable fees and
expenses; (b) then due and payable interest payments and mandatory prepayments;
and (c) then due and payable principal payments and optional prepayments.

         Bank is hereby authorized by Borrowers to endorse on Bank's book and
records each Advance made by Bank under this Note and the amount of each payment
or prepayment of principal of each such Advance received by Bank; it being
understood, however, that failure to make any such endorsement (or any errors in
notation) shall not affect the obligations of Borrowers with respect to Advances
made hereunder, and payments of principal by Borrowers shall be credited to
Borrower notwithstanding the failure to make a notation (or any errors in
notation) thereof on such books and records.

         Each Borrower promises to pay Bank all costs and expenses of collection
of this Note and to pay all reasonable attorneys' fees incurred in such
collection or in any suit or action to collect this Note or in any appeal
thereof. Borrowers waive presentment, demand, protest, notice of protest, notice
of dishonor, notice of nonpayment, and any and all other notices and demands in 
connection with the delivery, acceptance, performance, default or enforcement of
this Note, as well as any applicable statute of limitations. No delay by Bank in
exercising any power or right hereunder shall operate as a waiver of any power
or right. Time is of the essence as to all obligations hereunder.

         This Note is issued pursuant to the Loan Agreement, which shall govern
the rights and obligations of Borrower with respect to all obligations
hereunder.

         This Note shall be deemed to be made under, and shall be construed in
accordance with and governed by, the laws of the State of California, excluding
conflicts of laws principles.

================================================================================

BORROWER: Synon, Inc.                      LENDER: Silicon Valley Bank
          Synon Corporation                        Embarcadero/Technology
          1100 Larkspur Landing Circle             1731 Embarcadero, Suite 220
          Larkspur, CA 94939                       Palo Alto, CA 94303

================================================================================
                             INITIAL RATE: 11.000%
PRINCIPAL AMOUNT: $4,000,000.00                      DATE OF NOTE: JUNE 5, 1995

PROMISE TO PAY. Synon, Inc. and Synon Corporation ("Borrower") promise to pay
to Silicon Valley Bank ("Lender"), or order, in lawful money of the United
States of America, the principal amount of Four Million & 00/100 Dollars
($4,000,000.00) or so much as may be outstanding, together with interest on the
unpaid outstanding principal balance of each advance. Interest shall be
calculated from the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal
plus all accrued unpaid interest on May 31, 1996. In addition, Borrower will pay
regular monthly payments of accrued unpaid interest beginning July 31, 1995, and
all subsequent interest payments are due on the same day of each month after
that. Interest on this Note is computed on a 365/360 simple interest basis; that
is, by applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual number
of days in the principal balance is outstanding. Borrower will pay Lender at
Lender's address shown above or at such other place as Lender may designate in
writing. Unless otherwise agreed or required by applicable law, payments will be
applied first to accrued unpaid interest, then to principal, and any remaining
amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change
from time to time based on changes in an index which is Lender's Prime Rate
(the "Index"). This is the rate Lender charges, or would charge, on 90-day
unsecured loans to the most creditworthy corporate customers. This rate may or
may not be the lowest rate available from Lender at any given time. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each time the prime rate is
adjusted by Silicon Valley Bank. The Index currently is 9.000% per annum. The
interest rate to be applied to the unpaid principal balance of this Note will
be at a rate of 2.000 percentage points over the Index, resulting in an initial
rate of 11.000% per annum. NOTICE: Under no circumstances will the interest
rate on this Note be more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed
earlier than it is due. Early payments will not, unless agreed to by Lender in
writing, relieve Borrower of Borrower's obligation to continue to make payments
of accrued unpaid interest. Rather, they will reduce the principal balance due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to perform promptly at the time
and strictly in the manner provided in this Note or any agreement related to
this Note, or in any other agreement or loan Borrower has with Lender. (c)
Borrower defaults under any loan, extension of credit, security agreement,
purchase or sale agreement, or any other agreement, in favor of any other
creditor or person that may materially affect any of Borrower's property or
Borrower's ability to repay this Note or perform Borrower's obligations under
this Note or any of the Related Documents. (d) Any representation or statement
made or furnished to Lender by Borrower or on Borrower's behalf is false or
misleading in any material respect. (e) Borrower dies or becomes insolvent, a
receiver is appointed for any part of Borrower's property, Borrower makes an
assignment for the benefit of creditors, or any proceeding is commenced either
by Borrower or against Borrower under any bankruptcy or insolvency laws. (f)
Any creditor tries to take any of Borrower's property on or in which Lender has
a lien or security interest. This includes a garnishment of any of Borrower's
accounts with Lender. (g) Any of the events described in this default section
occurs with respect to any guarantor of this Note.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon Borrower's failure to pay
all amounts declared due pursuant to this section, including failure to pay
upon final maturity, Lender, at its option, may also, if permitted under
applicable law, do one or both of the following: (a) increase the variable
interest rate on this Note to 7.000 percentage points over the Index, and (b)
add any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Note (including any increased
rate). Lender may hire or pay someone else to help collect this Note if
Borrower does not pay. Borrower also will pay Lender that amount. This
includes, subject to any limits under applicable law, Lender's attorneys' fees
and Lender's legal expenses whether or not there is a lawsuit, including
attorneys' fees and legal expenses for bankruptcy proceedings (including
efforts to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgment collection services. Borrower also will pay any court
costs, in addition to all other sums provided by law. This Note has been
delivered to Lender and accepted by Lender in the State of California. If there
is a lawsuit, Borrower agrees upon Lender's request to submit to the
jurisdiction of the courts of Santa Cruz County, the State of California.
(Initial here _______). Lender and Borrower hereby waive the right to any jury
trial in any action, proceeding, or counterclaim brought by either Lender or
Borrower against the other. This Note shall be governed by and construed in
accordance with the laws of the State of California.

LINE OF CREDIT. This Note evidence a revolving line of credit. Advances under
this Note, as well as directions for payment from Borrower's accounts, may be
requested orally or in writing by Borrower or by an authorized person. Lender
may, but need not, require that all oral requests be confirmed in writing.
Borrower agrees to be liable for all sums either: (a) advanced in accordance
with the instructions of an authorized person or (b) credited to any of
Borrower's accounts with Lender. The unpaid principal balance owing on this
Note at any time may be evidenced by endorsements on this Note or by Lender's
internal records, including daily computer print-outs. Lender will have no
obligations to advance funds under this Note if: (a) Borrower or any guarantor
is in default under the term of this Note or any agreement that Borrower or any
guarantor has with Lender, including any agreement made in connection with the
signing of this Note; (b) Borrower or any guarantor ceases doing business or is
insolvent; (c) any guarantor seeks, claims or otherwise attempts to limit,
modify or revoke such guarantor's guarantee of this Note or any other loan with
Lender; or (d) Borrower has applied funds provided pursuant to this Note for
purposes other than those authorized by Lender.

REQUEST TO DEBIT ACCOUNTS. Borrower will regularly deposit all funds received
from its business activities in accounts maintained by Borrower at Silicon
Valley Bank. Borrower hereby requests and authorizes Lender to debit any of
Borrower's accounts with Lender, specifically, without limitation, Account
Number 02721376-70, for payments of principal and interest due on the loan and
any other obligations owing by Borrower to Lender. Lender will notify Borrower
of all debits which Lender makes against Borrower's accounts. Any such debits
against Borrower's accounts in no way shall be deemed a set-off.

LOAN AND SECURITY AGREEMENT. This Note is subject to and shall be governed by
all the terms and conditions of the Loan and Security Agreement dated March,
1994 between Lender and Borrower, as the same may be amended from time to time,
which Business Loan Agreement is incorporated herein by reference.

                                 PROMISSORY NOTE

================================================================================

Borrower:  Synon, Inc. and Synon Corporation      Lender:  Silicon Valley Bank
           1100 Larkspur Landing Circle                    3003 Tasman Drive
           Larkspur, CA 94939                              Santa Clara, CA 95054

================================================================================

Principal                  Initial 
Amount:     $400,000.00    Rate:     10.000%      Date of Note: July 15, 1996

PROMISE TO PAY Synon, Inc. and Synon Corporation ("Borrower") promises to pay to
Silicon Valley Bank ("Lender"), or order, in lawful money of the United States
of America, the principal amount of Four Hundred Thousand and 00/100 Dollars
($400,000.00) or so much as may be outstanding, together with interest on the
unpaid outstanding principal balance of each advance. Interest shall be
calculated from the date of each advance until repayment of each advance.

PAYMENT.  Borrower will pay this loan in accordance with the following
payment schedule:

  The Draw Period shall begin as of this date and shall end on April 15, 1997
  (the "Draw Period"). During the Draw Period, Borrower shall pay regular
  monthly payments of all accrued unpaid interest due as of each payment date,
  beginning August 15, 1996 and all subsequent interest payments will be due on
  the same day of each month thereafter. The outstanding principal balance on
  April 15, 1997, will be payable in twenty-four (24) even payments of principal
  plus interest will be due as of each payment date, beginning May 15,1997 and
  all subsequent payments of principal plus interest will be due on the same day
  of each month thereafter. The final payment, due, on April 15, 1999, will be
  for all outstanding principal plus all accrued interest not yet paid.

Interest on this Note is computed on a 365/360 simple interest basis; that is,
by applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual number
of days the principal balance is outstanding. Borrower will pay Lender at
Lender's address shown above or at such other place as Lender may designate in
writing. Unless otherwise agreed or required by applicable law, payments will be
applied first to accrued unpaid interest, then to principal, and any remaining
amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an index which is Lender's Prime Rate (the
"Index"). This is the rate Lender charges, or would charge, on 90-day unsecured
loans to the most creditworthy corporate customers. This rate may or may not be
the lowest rate available from Lender at any given time. Lender will tell
Borrower the current Index rate upon Borrower's, request. Borrower understands
that Lender may make loans based on other rates as well. The interest rate
change will not occur more often than each time the prime rate is adjusted by
Silicon Valley Bank. The Index currently is 8.250 per annum. The interest rate
to be applied to the unpaid principal balance of this Note will be at a rate of
1.750 percentage point over the Index, resulting in an initial rate of 10.000%
per annum. NOTICE: Under no circumstances will the interest rate on this Note be
more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges
are earned fully as of the date of the loan and will not be subject to refund
upon early payment (whether voluntary or as a result of default), except as
otherwise required by law. Except for the foregoing, Borrower may pay without
penalty all or a portion of the amount owed earlier than it is due. Early
payments will not, unless agreed to by Lender in writing, relieve Borrower of
Borrower's obligation to continue to make payments of accrued unpaid interest.
Rather, they will reduce the principal balance due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to perform promptly at the time
and strictly in the manner provided in this Note or any agreement related to
this Note, or in any other agreement or loan Borrower has with Lender. (c)
Borrower defaults under any loan, extension of credit, security agreement,
purchase or sales agreement, or any other agreement, in favor of any other
creditor or person that may materially affect any of Borrower's property or
Borrower's ability to repay this Note or perform Borrower's obligations under
this Note or any of the Related Documents. (d) Any representation or statement
made or furnished to Lender by Borrower or on Borrowers behalf is false or
misleading in any material respect. (e) Borrower becomes insolvent, a receiver
is appointed for any part of Borrower's property, Borrower makes an assignment
for the benefit of creditors, or any proceeding is commenced either by Borrower
or against Borrower under any bankruptcy or insolvency laws. (f) Any creditor
tries to take any of Borrower's property on or in which Lender has a lien or
security interest. This includes a garnishment of any of Borrower's accounts
with Lender. (g) Any of the events described in this default section occurs with
respect to any guarantor of this Note.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon Borrowers failure to pay
all amounts declared due pursuant to this section, including failure to pay upon
final maturity, Lender, at its option, may also, if permitted under applicable
law, do one or both of the following: (a) increase the variable interest rate on
this Note to 5.000 percentage points over the otherwise effective interest rate,
and (b) add any unpaid accrued interest to principal and such sum will bear
interest therefrom until paid at the rate provided in this Note (including any
increased rate). Lender may hire or pay someone else to help collect this Note
if Borrower does not pay. Borrower also will pay Lender that amount. This
includes, subject to any limits under applicable law, Lenders attorneys' fees
and Lender's legal expenses whether or not there is a lawsuit, including
attorneys' fees and legal expenses for bankruptcy proceedings (including efforts
to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgment collection services. Borrower also will pay any court
costs, in addition to all other sums provided by law. THIS NOTE HAS BEEN
DELIVERED TO LENDER AND ACCEPTED BY LENDER IN THE STATE OF CALIFORNIA. IF THERE
IS A LAWSUIT, BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE
JURISDICTION OF THE COURTS OF SANTA CLARA COUNTY, THE STATE OF CALIFORNIA.
(INITIAL HERE  /s/ PW). Lender and Borrower hereby waive the right to any jury
trial in any action, proceeding, or counterclaim brought by either Lender or
Borrower against the other. This Note shall be governed by and construed in
accordance with the laws of the State of California.

                                 PROMISSORY NOTE
                                    CONTINUED

LINE OF CREDIT. This note evidences a straight line of credit through the end of
the Draw Period. Once the total amount of principal has been advanced, Borrower
is not entitled to further loan advances. Advances under this Note, as well as
directions for payment from Borrower's accounts, may be requested orally or in
writing by Borrower or by an authorized person. Lender may, but need not,
require that all oral requests be confirmed in writing. Borrower agrees to be
liable for all sums either: (a) advanced in accordance with the instructions of
an authorized person or (b) credited to any of Borrowers accounts with Lender.
The unpaid principal balance owing on this Note at any time may be evidenced by
endorsements on this Note or by Lender's internal records, including daily
computer print-outs. Lender will have no obligation to advance funds under this
Note if; (a) Borrower or any guarantor is in default under the terms of this
Note or any agreement that Borrower or any guarantor has with Lender, including
any agreement made in connection with the signing of this Note; (b) Borrower or
any guarantor ceases doing business or is insolvent; (c) any guarantor seeks,
claims or otherwise attempts to limit, modify or revoke such guarantors
guarantee of this Note or any other loan with Lender; or (d) Borrower has
applied funds provided pursuant to this Note for purposes other than those
authorized by Lender.

ADVANCE RATE. At any time from the date hereof through the end of the Draw
Period, Borrower may request advances (each an "Equipment Advance" and
collectively, the "Equipment Advances") from Lender in an aggregate amount not
to exceed the principal amount of this Note. To evidence the Equipment Advances,
Borrower shall deliver to Lender, at the time of each advance request, an
invoice for the equipment to be purchased. The Advances shall be used only to
purchase equipment and shall not exceed one hundred percent (100%) of the
invoice amount approved from time to time by Lender, excluding taxes, shipping,
software and installation expense. Software may, however, constitute up to

                    INTELLECTUAL PROPERTY SECURITY AGREEMENT

        This Intellectual Property Security Agreement is made as of March 17,
1994, by and between SYNON CORPORATION, a Delaware corporation ("Grantor"), and
SILICON VALLEY BANK, a California banking corporation ("Grantee").

                                    RECITALS

        A.      Grantee has agreed to lend to Grantor certain funds (the
"Loan"), and Grantor desires to borrow such funds from Grantee. The Loan will be
evidenced by one or more promissory notes of even date herewith (a "Note" or,
collectively, the "Notes") and will be secured in part pursuant to the terms of
a Loan and Security Agreement of even date herewith (the "Loan Agreement").

        B.      In order to induce Grantee to make the Loan, Grantor has agreed
to assign certain intangible property to Grantee for purposes of securing the
obligations of Grantor to Grantee.

        NOW, THEREFORE, THE PARTIES HERETO AGREE AS FOLLOWS:

        1.      Grant of Security Interest.  As collateral security for the
prompt and complete payment and performance of all of Grantor's present or
future indebtedness, obligations and liabilities to Grantee, Grantor hereby
grants a security interest to Grantee in and to Grantor's entire right, title
and interest in, to and under the following (all of which shall collectively be
called the "Collateral")":

                (a)     Any and all copyright rights, copyright applications,
copyright registrations and like protections in each work or authorship and
derivative work thereof, whether published or unpublished and whether or not
the same also constitutes a trade secret, now or hereafter existing, created,
acquired or held, including without limitation those set forth on Exhibit A
attached hereto (collectively, the "Copyrights");

                (b)     Any and all trade secrets, and any and all intellectual
property rights in computer software and computer software products now or
hereafter existing, created, acquired or held;

                (c)     Any and all design rights which may be available to
Grantor now or hereafter existing, created, acquired or held;

                (d)     All patents, patent applications and like protections
including without limitation improvements, divisions, continuations, renewals,
reissues, extensions and continuations-in-part of the same, including without
limitation the patents and patent applications set forth on Exhibit B attached
hereto (collectively, the "Patents");

                (e)     Any trademark and servicemark rights, whether
registered or not, applications to register and registrations of the same and
like protections, and the entire goodwill of the business of Grantor connected
with and symbolized by such trademarks, including without limitation those set
forth on Exhibit C attached hereto (collectively, the "Trademarks");

                (f)     Any and all claims for damages by way of past, present
and future infringement of any of the rights included above, with the right,
but not the obligation, to sue for and collect such damages for said use or
infringement of the intellectual property rights identified above;




                                       1

<PAGE>   2
                (g)     All licenses or other rights to use any of the
Copyrights, Patents or Trademarks, and all license fees and royalties arising
from such use to the extent permitted by such license or rights; and

                (h)     All amendments, renewals and extensions of any of the
Copyrights, Trademarks or Patents; and

                (i)     All proceeds and products of the foregoing, including
without limitation all payments under insurance or any indemnity or warranty
payable in respect of any of the foregoing.

        Notwithstanding the foregoing, Grantor shall not be deemed to have
granted a security interest in any rights under any license which by its terms
prohibits the grant of a security interest.

        2.      Authorization and Request.  Grantor authorizes and requests
that the Register of Copyrights and the Commissioner of Patents and Trademarks
record this security agreement.

        3.      Covenants and Warranties.  Grantor represents, warrants,
covenants and agrees as follows:

                (a)     Grantor is now the sole owner of the Collateral, except
for non-exclusive licenses granted by Grantor to its customers in the ordinary
course of business and security interests in certain items of Collateral granted
to former owners of such Collateral;

                (b)     Assuming notice is given to the sellers under certain
Asset Purchase Agreements pursuant to which certain items of Collateral were
acquired, performance of this Security Agreement does not conflict with or
result in a breach of any agreement to which Grantor is party or by which
Grantor is bound, except to the extent that certain intellectual property
agreements prohibit the assignment of the rights thereunder to a third party
without the licensor's or other party's consent and this Security Agreement
constitutes an assignment;

                (c)     During the term of this Security Agreement, Grantor
will not transfer or otherwise encumber any interest in the Collateral, except
for non-exclusive licenses granted by Grantor in the ordinary course of
business or as set forth in this Security Agreement;

                (d)     To its knowledge, each of the Patents is valid and
enforceable, and no part of the Collateral has been judged invalid or
unenforceable, in whole or in part, and no claim has been made that any part of
the Collateral violates the rights of any third party;

                (e)     Grantor shall promptly advise Grantee of any material
change in the composition of the Collateral, including but not limited to any
subsequent ownership right of the Grantor in or to any Trademark, Patent or
Copyright not specified in this Security Agreement;

                (f)     Grantor shall (i) protect, defend and maintain the
validity and enforceability of the Trademarks, Patents and Copyrights, (ii) use
its best efforts to detect infringements of the Trademarks, Patents and
Copyrights and promptly advise Grantee in writing of material infringements
detected and (iii) not allow any Trademarks, Patents or Copyrights to be
abandoned, forfeited or dedicated to the public without the written consent of
Grantee, which shall not be unreasonably withheld, unless Grantor determines
that reasonable business practices suggest that abandonment is appropriate.

                (g)     Grantor shall register the most recent versions of any
of Grantor's Copyrights in accordance with the provisions of Section 6.10 of
the Loan Agreement, and shall, from time to time, execute and file such other
instruments, and take such further actions as Grantee may reasonably request
from time to time to perfect or continue the perfection of Grantee's interest
in the Collateral;

                (h)     Except with respect to those items of Collateral in
which the party from which Grantor acquired such item of Collateral retains a
security interest to secure a portion of the acquisition




                                       2

price, this Security Agreement creates, and in the case of after acquired
Collateral, this Security Agreement will create at the time Grantor first has
rights in such after acquired Collateral, in favor of Grantee a valid first
priority security interest in the Collateral in the United States securing the
payment and performance of the obligations evidenced by the Note upon making
the filings referred to in clause (i) below;

                (i)     To its knowledge, except for, and upon, the filing 
with the United States Patent and Trademark office with respect to the Patents
and Trademarks and the Register of Copyright with respect to the Copyrights
necessary to perfect the security interests and assignment created hereunder,
and except as has been already made or obtained, no authorization, approval or
other action by, and no notice to or filing with, any U.S. governmental
authority or U.S. regulatory body is required either (i) for the grant by
Grantor of the security interest granted hereby or for the execution, delivery
or performance of this Security Agreement by Grantor in the U.S. or (ii) for the
perfection in the United States or the exercise by Grantee of its rights and
remedies hereunder, provided that Grantor makes no representation with respect
to unregistered copyrights.

                (j)     To the best of Grantor's knowledge, all information 
heretofore, herein or hereafter supplied to Grantee by or on behalf of Grantor
with respect to the Collateral is accurate and complete in all material 
respects.

                (k)     Grantor shall not enter into any agreement that would
materially impair or conflict with Grantor's obligations hereunder without
Grantee's prior written consent, which consent shall not be unreasonably
withheld. Without Grantee's prior written consent, which shall not be
unreasonably withheld, Grantor shall not permit the inclusion in any material
contract to which it become a party of any provisions that could or might in
any way prevent the creation of a security interest in Grantor's rights and
interests in any property included within the definition of the Collateral
acquired under such contracts.

                (l)     Upon any executive officer of Grantor obtaining actual
knowledge thereof, Grantor will promptly notify Grantee in writing of any event
that materially adversely affects the value of any Collateral, the ability of
Grantor to dispose of any Collateral or the rights and remedies of Grantee in
relation thereto, including the levy of any legal process against any of the 
Collateral.

        4.      Grantee's Rights.  Grantee shall have the right, but not the
obligation, to take, at Grantor's sole expense, any actions that Grantor is
required under this Security Agreement to take but which Grantor fails to take,
after fifteen (15) days' notice to Grantor. Grantor shall reimburse and
indemnify Grantee for all reasonable costs and reasonable expenses incurred in
the reasonable exercise of its rights under this section 4.

        5.      Inspection Rights.  Grantor hereby grants to Grantee and its
employees, representatives and agents the right to visit, during reasonable
hours upon prior reasonable written notice to Grantor, and of Grantor's plants
and facilities that manufacture, install or store products (or that have done so
during the prior six-month period) that are sold utilizing any of the
Collateral, and to inspect the products and quality control records relating
thereto upon reasonable written notice to Grantor and as often as may be
reasonably requested.

        6.      Further Assurances; Attorney in Fact.

                (a)     On a continuing basis in accordance with the provisions
of Section 6.10 of the Loan Agreement, Grantor will, subject to any prior
licenses, encumbrances and restrictions and prospective licenses, make, execute,
acknowledge and deliver, and file and record in the proper filing and recording
places in the United States, all such instruments, including appropriate
financing and continuation statements and collateral agreements and filings
with the United States Patent and Trademark Office and the Register of
Copyrights, and take all such action as may reasonably be deemed necessary or
advisable, or as requested by Grantee, to perfect Grantee's security interest
in all Copyrights, Patents and Trademarks and otherwise to carry out the intent
and purposes of this Security Agreement or for assuring and confirming to
Grantee the grant or perfection of a security interest in all Collateral.

<PAGE>   4
                (b)     Grantor hereby irrevocably appoints Grantee as Grantor's
attorney-in-fact, with full authority in the place and stead of Grantor and in
the name of Grantor, from time to time in Grantee's discretion, to take any
action and to execute any instrument which Grantee may deem necessary or
advisable to accomplish the purposes of this Security Agreement, including:

                        (i)     To modify, in its sole discretion, this
Security Agreement without first obtaining Grantor's approval of or signature to
such modification by amending Exhibit A, Exhibit B and Exhibit C, thereof, as
appropriate, to include reference to any right, title or interest in any
Copyrights, Patents or Trademarks acquired by Grantor after the execution hereof
or to delete any reference to any right, title or interest in any Copyrights,
Patents or Trademarks in which Grantor no longer has or claims any right, title
or interest; and

                        (ii)    To file, in its sole discretion, one or more
financing or continuation statements and amendments thereto, relative to any of
the Collateral without the signature of Grantor where permitted by law.

        7.      Events of Default. The occurrence of any of the following shall
constitute an Event of Default under this Security Agreement:

                (a)     An Event of Default occurs under the Loan Agreement or
any Note; or

                (b)     Grantor breaches any warranty or agreement made by
Grantor in this Security Agreement and, as to any breach that is capable of
cure, Grantor fails to cure such breach within fifteen (15) days of the
occurrence of such breach.

        8.      Remedies. Upon the occurrence and continuance of an Event of
Default, Grantee shall have the right to exercise all the remedies of a secured
party under the California Uniform Commercial Code, including without limitation
the right to require Grantor to assemble the Collateral and any tangible
property in which Grantee has a security interest and to make it available to
Grantee at a place designated by Grantee. Grantee shall have a nonexclusive,
royalty free license to use the Copyrights, Patents and Trademarks to the extent
reasonably necessary to permit Grantee to exercise its rights and remedies upon
the occurrence and during the continuation of an Event of Default. Grantor will
pay any expenses (including reasonable attorneys' fees) incurred by Grantee in
connection with the exercise of any of Grantee's rights hereunder, including
without limitation any expense incurred in disposing of the Collateral. All of
Grantee's rights and remedies with respect to the Collateral shall be
cumulative.

        9.      Indemnity. Grantor agrees to defend, indemnify and hold
harmless Grantee and its officers, employees, and agents against: (a) all
obligations, demands, claims, and liabilities claimed or asserted by any other
party in connection with the transactions contemplated by this Security
Agreement, and (b) all losses or expenses in any way suffered, incurred, or
paid by Grantee as a result of or in any way arising out of, following or
consequential to transactions between Grantee and Grantor, arising out of this
Security Agreement (including without limitation reasonable attorneys' fees and
reasonable expenses), except for losses arising from or out of Grantee's gross
negligence or willful misconduct.

       10.      Release. At such time as Grantor shall completely satisfy all
of the obligations secured hereunder, Grantee shall execute and deliver to
Grantor all instruments as may be necessary or proper to release Grantor's
security interest granted hereunder, subject to any disposition thereof which
may have been made by Grantee pursuant hereto.

       11.      Course of Dealing. No course of dealing, nor any failure to
exercise, nor any delay in exercising any right, power or privilege hereunder
shall operate as a waiver thereof.

       12.      Attorneys' Fees. If any action relating to this Security
Agreement is brought by either party hereto against the other party, the
prevailing party shall be entitled to recover reasonable attorneys' fees, costs
and disbursements.

        13.     Amendments.  This Security Agreement may be amended only by a
written instrument signed by both parties hereto.

        14.     Counterparts.  This Security Agreement may be executed in two
or more counterparts, each of which shall be deemed an original but all of
which together shall constitute the same instrument.

        15.     California Law and Jurisdiction.  This Security Agreement shall
be governed by the laws of the State of California, without regard for choice
of law provisions. Grantor and Grantee consent to the nonexclusive jurisdiction
of any state or federal court located in Santa Clara County, California.

        16.     Confidentiality.  In handling any confidential information Bank
shall exercise the same degree of care that it exercises with respect to its
own proprietary information of the same types to maintain the confidentiality
of any non-public information thereby received or received pursuant to this
Agreement except that disclosure of such information may be made (i) to the
subsidiaries or affiliates of Bank in connection with their present or
prospective business relations with Borrower; (ii) to prospective transferees
or purchasers of any interest in the Loans, provided that they have entered
into a comparable confidentiality agreement in favor of Borrower and have
delivered a copy to Borrower, (iii) as required by law, regulations, rule or
order, subpoena, judicial order or similar order and (iv) as may be required in
connection with the examination, audit or similar investigation of Bank.
Notwithstanding any provision of this Agreement to the contrary, prior to the
occurrence of an Event of Default neither Borrower nor any of its Subsidiaries
will be required to disclose, permit the inspection, examination, copying or
making extracts of, or discussions of, any document, information or other
matter that (i) constitutes non-financial trade secrets or non-financial
proprietary information, or (ii) in respect to which disclosure to Bank (or
designated representative) is then prohibited by (a) law, or (b) an agreement
binding upon Borrower or any Subsidiary that was not entered into by Borrower
or such Subsidiary for the primary purpose of concealing information from Bank.

        IN WITNESS WHEREOF, the parties hereto have executed this Security
Agreement on the day and year first above written.

           voting power of the voting securities of Synon (exclusive of persons
           who are now officers of directors of Synon).

           For purposes of the foregoing, your employment with Synon shall be
           deemed to have been "Constructively Terminated" if there shall occur
           (i) a material reduction in salary or benefit (taken as a whole),
           (ii) a material change in responsibility, or (iii) a requirement to
           relocate, except for office relocations that would not increase your

         TERMINATION PERIOD:

           Options may only be exercised while you are an Employee of the

         EXERCISE AND VESTING SCHEDULE:

           This option may be exercised, in whole or in part, in accordance with
           the Vesting Schedule set forth below.

           DATE OF VESTING:                                FEBRUARY 7, 1993

           NUMBER OF SHARES:                               44,000

           FOR EACH OF THE 48 MONTHS FOLLOWING 
           FEBRUARY 7, 1993:                               1.667% OF 220,000

           In addition, (i) upon any Change of Control of Synon Corporation (as
           defined herein) or initial public offering by Synon Corporation,
           whichever occurs first, 50% of any unvested shares will vest
           automatically and any of the then remaining unvested options will
           vest monthly in equal increments over the balance of the two year
           vesting period and (ii) if your employment is involuntarily
           terminated or Constructively Terminated (as defined herein) within
           twelve (12) months after a Change of Control (it being the intention
           that you will agree to remain employed for at least one year
           following a "Change of Control"), then your option shall be
           accelerated to become immediately exercisable for 100% of the total
           number of unvested shares subject thereto.

           For purposes of the foregoing, a "Change of Control of Synon" shall
           be deemed to have occurred if (i) Synon sells or otherwise disposes
           of all or substantially all of its 
<PAGE>   2

           assets; (ii) there is a merger or consolidation of Synon with any
           other corporation or corporations, provided that the shareholders of
           Synon, as a group, do not hold, immediately after such event, at
           least 50% of the voting power of the surviving or successor
           corporation; (iii) any person or entity, including any "person" as
           such term is used in Section 13(d) (3) of the Securities Exchange Act
           of 1934, as amended (the "Exchange Act") becomes the "beneficial
           owner" (as defined in the Exchange Act) of Common Stock of Synon
           representing 50% or more of the combined voting power of the voting
           securities of Synon (exclusive of persons who are now officers of
           directors of Synon).

           For purposes of the foregoing, your employment with Synon shall be
           deemed to have been "Constructively Terminated" if there shall occur
           (i) a material reduction in salary or benefit (taken as a whole),
           (ii) a material change in responsibility, or (iii) a requirement to
           relocate, except for office relocations that would not increase your
           one-way commute by more than 50 miles.

         TERMINATION PERIOD:

           Options may only be exercised while you are an Employee of the
           Company except as set out in Sections 7 and 8 of the Stock Option
           Agreement (but in no event later than the Expiration Date); provided,
           however, that upon termination of your employment with the Company,
           the Administrator may, in its sole discretion, permit you to exercise
           the Option, to the extent already exercisable, during a period ending
