VIGNETTE: INTERNET RELATIONSHIP MANAGEMENT SOLUTIONS
 
  It's clear that merely having a Web site on the Internet is not enough to
increase online revenues. Businesses must build relationships that deliver the
right information at the right time. In addition, to increase the return on
Internet investments businesses must create multiple contact points by
providing information on third-party Web sites. The bottom line is simple:
Vignette offers the solutions that build Internet relationships.
 
  [Graphic of two individuals shaking hands; graphic of a computer with a
banner reading "Everyone Welcome."]
 
TO BUILD AN ONLINE BUSINESS, BUILD CUSTOMER RELATIONSHIPS.
 
  To date, most businesses can't get a quality return on their Internet
investment because they aren't building relationships that turn one-time
visitors into long-term customers. To increase returns, companies must manage
content in a way that provides the value and convenience to stimulate buying
and ongoing customer loyalty.
 
  [An arrow from the computer, labeled "One-time visitors become long-term
customers,"' points to another computer with a banner reading "Welcome Jim."

VIGNETTE STORYSERVER 4. IT'S TIME TO GET PERSONAL.
 
  With Vignette StoryServer 4, businesses can manage content in an intelligent
fashion, personalizing the experience for the Web site visitor throughout the
visitor's customer lifecycle. As a result, long-term, customer relationships
can be built and the resulting revenues offer a superior return on the
company's Internet investment.
 
  [An arrow, labeled "Customers may not come to you, so you need to go to
them," points from the second computer to a graphic of an individual standing
before a large computer with a banner reading, "Welcome Jim" and labeled,
"Company Web Site." Six smaller graphics of an individual standing before a
computer surround the large computer; each of the six is connected to the
large computer by a double-headed arrow. Each small computer has a banner and
a label: "Hi Jim" and "Vendor," "Hey Jim" and "Distributor," "Go Jim!" and
"Online Catalog," "Enter Jim" and "Resellers," "Hello Jim" and "Retailer," and
"Jim!" and "Portal," respectively.]
 
VIGNETTE SYNDICATION SERVER. THE RIGHT INFORMATION, AT THE RIGHT TIME, IN THE
RIGHT PLACE.
 
  Once StoryServer 4 is in place building relationships, companies can expand
revenue opportunities by creating additional customer contact points.
Beginning in the first quarter of 1999, companies can use the Vignette
Syndication Server to place content on third-party sites allowing them to
build a powerful distribution network that puts their products in direct
access to the customers wherever they are.

                               PROSPECTUS SUMMARY
 
  You should read this summary together with the more detailed information and
our consolidated financial statements and notes appearing elsewhere in this
Prospectus.
                                  THE COMPANY
 
  Vignette is a leading provider of Internet Relationship Management ("IRM")
software products and services. The Company's IRM solutions, which represent a
new category of enterprise applications, are designed to enable businesses to
build sustainable online customer relationships and increase Web-based revenues
and market share. Our StoryServer 4 application platform integrates advanced
content management, lifecycle personalization and decision support tools to
allow our clients to engage their Web site visitors with personalized
interactions that stimulate buying and strengthen customer loyalty. Our
Vignette Syndication Server ("VSS") platform, which we formally announced in
October 1998 and expect to ship in the first quarter of 1999, is designed to
enable a business to distribute its electronic goods and services outside of
its own Web site through a network of reseller, affiliate, and partner Web
sites, or its "Customer Chain." The capabilities of VSS will enable our clients
to establish super-distribution networks on the Internet to extend online reach
and increase Web-based revenue opportunities. We complement our products with a
professional services organization that offers strategic planning, project
management and implementation services.
 
  To date, we have licensed the StoryServer software platform to more than 160
clients worldwide in a variety of industries including retail, financial
services, telecommunications, technology and media. Our customers include Bank
One, Bay Networks, Chicago Tribune, Lands' End, National Semiconductor, Preview
Travel, and Ziff Davis Publishing. Since shipping our first products in 1997,
we have received 11 awards for our industry leadership and product capabilities
including Best Products/Best Private Company from The Red Herring magazine and
the Editor's Choice Award from Seybold Publications.

LIMITED OPERATING HISTORY; HISTORY OF LOSSES AND EXPECTATION OF FUTURE LOSSES
 
  Vignette was founded in December 1995 and has a limited operating history.
An investor in our Common Stock must consider the risks and difficulties
frequently encountered by early stage companies in new and rapidly evolving
markets. These risks include our:
 
  . Dependence on our StoryServer product;
 
  . Need to expand our sales and professional services organizations;
 
  . Ability to develop and upgrade our technology;
 
  . Ability to compete in a highly competitive market;
 
  . Need to manage expanding operations;
 
  . Ability to maintain sufficiently high utilization rates for professional
    services personnel;
 
  . Continued reliance on strategic relationships; and
 
  . Dependence on key personnel.
 
  We also depend on the growing use of the Internet for commerce and
communication and on general economic conditions. We cannot be certain that we
will successfully address any of these risks.
 
  We incurred net losses of $3.6 million for the year ended December 31, 1996,
$7.5 million for the year ended December 31, 1997 and $16.3 million for the
nine months ended September 30, 1998. As of September 30, 1998, we had an
accumulated deficit of $27.4 million. We have not achieved profitability and
we expect to incur net losses for the foreseeable future. We expect to
continue to incur significant product development, sales and marketing, and
administrative expenses and, as a result, we will need to generate significant
revenues to achieve and maintain profitability. Although our revenues have
grown significantly in recent quarters, we cannot be certain that we can
sustain these growth rates or that we will achieve sufficient revenues for
profitability. If we do achieve profitability, we cannot be certain that we
can sustain or increase profitability on a quarterly or annual basis in the
future. See "Selected Consolidated Financial Data" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
QUARTERLY FINANCIAL RESULTS ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS AND
SEASONALITY
 
  As a result of our limited operating history, we cannot forecast operating
expenses based on our historical results. Accordingly, we base our expenses in
part on future revenue projections. Most of our expenses are fixed in the
short term and we may not be able to quickly reduce spending if our revenues
are lower than we had projected. Our ability to forecast accurately our
quarterly revenue is limited because our software products have
 
                                       4
<PAGE>
 
a long sales cycle that makes it difficult to predict the quarter in which
sales will occur. We would expect our business, operating results and
financial condition to be materially adversely affected if our revenues do not
meet our projections and that net losses in a given quarter would be even
greater than expected.
 
  We expect our revenues and operating results may vary significantly from
quarter to quarter. A number of factors are likely to cause these variations,
including:
 
  . Demand for our products and services;
 
  . The timing of sales of our products and services;
 
  . The timing of customer orders and product implementations;
 
  . Unexpected delays in introducing new products and services;
 
  . Increased expenses, whether related to sales and marketing, product
    development or administration;
 
  . Changes in the rapidly evolving market for IRM solutions;
 
  . The mix of product license and services revenue, as well as the mix of
    products licensed;
 
  . The mix of domestic and international sales; and
 
  . Costs related to possible acquisitions of technology or businesses.
 
  Accordingly, we believe that quarter-to-quarter comparisons of our operating
results are not necessarily meaningful. Investors should not rely on the
results of one quarter as an indication of our future performance.
 
  We plan to increase our operating expenses to expand our sales and marketing
operations, develop new distribution channels, fund greater levels of research
and development, broaden professional services and support, and improve
operational and financial systems. If our revenues do not increase along with
these expenses, our business, operating results or financial condition could
be materially adversely affected and net losses in a given quarter would be
even greater than expected.
 
  Although we have limited historical financial data, we believe that our
quarterly operating results may experience seasonal fluctuations. For
instance, quarterly results may fluctuate based on our clients' calendar year
budgeting cycles, slow summer purchasing patterns in Europe and our
compensation policies that tend to compensate sales personnel, typically in
the latter half of the year, for achieving annual quotas.
 
DEPENDENCE ON SMALL NUMBER OF LARGE ORDERS
 
  We derive a significant portion of our software license revenues in each
quarter from a small number of relatively large orders. For example, in five
of the last seven quarters in the period ended September 30, 1998, we had at
least one customer that accounted for at least 10% of total revenue in such
quarter. We do not believe that the loss of any particular customer would have
an adverse effect on our business. However, our operating results could be
materially adversely affected if we were unable to complete one or more
substantial license sales in any future period. We derive a substantial
portion of our revenue from the sale of products with related services. In
these cases, our revenue recognition policy requires us to substantially
complete the implementation of our product before we can recognize software
license revenue, and any end of quarter delays in product implementation could
materially adversely affect operating results for that quarter. As a result,
small delays in customer orders or product implementations can cause
significant variability in our license revenues and operating results for any
particular period.
 
DEPENDENCE ON STORYSERVER
 
  We currently derive all of our revenues from the license and related
upgrades, professional services and support of our StoryServer software
products, and we expect that we will continue to depend on revenue related to
new and enhanced versions of our StoryServer product line for at least the
next several quarters. We cannot be certain that we will be successful in
upgrading and marketing our products or that we will successfully develop and
market new products and services. If we do not continue to increase revenue
related to our existing products or generate revenue from new products and
services, our business, operating results and financial condition would be
materially adversely affected.
 
                                       5
<PAGE>
 
DEPENDENCE ON SUCCESSFUL INTRODUCTION OF VIGNETTE SYNDICATION SERVER
 
  We formally announced Vignette Syndication Server, or VSS, in October 1998
and we plan to ship VSS to clients in the first quarter of 1999. This will be
the first version of a new product designed for a new market opportunity.
There are significant risks inherent in a product introduction such as VSS. We
expect that our future financial performance will depend significantly on the
successful development, introduction and market acceptance of VSS and the
related tools that we plan to develop. Market acceptance of VSS will depend on
a market developing for Internet syndication products and services and the
commercial adoption of standards on which VSS is based. We cannot be certain
that either will occur. We cannot be certain that VSS will meet customer
performance needs or expectations when shipped or that it will be free of
significant software defects or bugs. If VSS does not meet customer needs or
expectations, for whatever reason, upgrading or enhancing the product could be
costly and time consuming.
 
NEED TO DEVELOP SALES AND DISTRIBUTION CAPABILITIES
 
  We will need to expand our direct and indirect sales operations in order to
increase market awareness of our products and generate increased revenue. We
have recently expanded our direct sales force and plan to hire additional
sales personnel. Our products and services require a sophisticated sales
effort targeted at the senior management of our prospective clients. New hires
will require training and take time to achieve full productivity. We cannot be
certain that our recent hires will become as productive as necessary or that
we will be able to hire enough qualified individuals in the future. We also
plan to expand our relationships with value-added resellers, systems
integrators and other third-party resellers to build an indirect sales
channel. We cannot be certain that we will be successful in these efforts. In
addition, we will need to manage potential conflicts between our direct sales
force and third-party reselling efforts.
 
LENGTHY SALES AND IMPLEMENTATION CYCLE
 
  Selling IRM software requires us to educate potential clients regarding the
use and benefits of IRM applications. As a result, our software products have
a long sales cycle that makes it difficult to predict the quarter in which
sales may fall. In addition, the implementation of our products requires a
significant commitment of resources by our clients, third-party professional
services organizations or our professional services organization. In many
cases, we recognize a substantial portion of the revenue from product sales
upon implementation of our product. Delays in product implementation could
cause significant variability in our license revenues and operating results
for any particular period.
 
RISKS ASSOCIATED WITH PROFESSIONAL SERVICES
 
  Clients that license our software typically engage our professional services
organization to assist with support, training, consulting and implementation.
We believe that growth in our product sales depends on our ability to provide
our clients with these services and to educate third-party resellers on how to
use our products. As a result, we plan to increase the number of service
personnel to meet these needs. New services personnel will require training
and education and take time to reach full productivity. To meet our needs for
services personnel, we may also need to use more costly third-party
consultants to supplement our own professional services organization. We
expect our services revenue to increase in absolute dollars as we continue to
provide consulting and training services that complement our products and as
our installed base of clients grows. To date, our services costs have been
significantly higher than our services revenue, and we expect that trend to
continue for the foreseeable future. We cannot be certain that our services
business will ever achieve profitability. We generally bill our clients for
our services on a "time and materials" basis. However, from time to time we
enter into fixed-price contracts for services. On occasion, the costs of
providing the services have exceeded our fees from these contracts and, from
time to time, we may misprice future contracts to our detriment. In addition,
competition for qualified services personnel is intense. We are in a new
market and there is a limited number of people who have acquired the skills
needed to provide the services that our clients demand. We cannot be certain
that we can attract or retain a sufficient number of the highly qualified
services personnel that our business needs.
 
RISKS ASSOCIATED WITH EMERGING MARKET
 
  The market for IRM software is new and rapidly evolving. We expect that we
will continue to need intensive marketing and sales efforts to educate
prospective clients about the uses and benefits of our products
 
                                       6
<PAGE>
 
and services. Enterprises that have already invested substantial resources in
other methods of conducting business may be reluctant or slow to adopt a new
approach that may replace, limit or compete with their existing systems.
Similarly, individuals have established patterns of purchasing goods and
services. They may be reluctant to alter those patterns. They may also resist
providing the personal data necessary to support our existing and potential
product uses. Any of these factors could inhibit the growth of online business
generally and the market's acceptance of our products and services in
particular. Accordingly, we cannot be certain that a viable market for our
products will emerge or be sustainable.
 
DEPENDENCE ON USE OF THE INTERNET FOR COMMERCE
 
  Our future success depends heavily on the Internet being accepted and widely
used for commerce. Consumers and businesses may reject the Internet as a
viable commercial medium for a number of reasons, including potentially
inadequate network infrastructure, slow development of enabling technologies
or insufficient commercial support. The Internet infrastructure may not be
able to support the demands placed on it by increased Internet usage and
bandwidth requirements. In addition, delays in the development or adoption of
new standards and protocols required to handle increased levels of Internet
activity, or increased government regulation could cause the Internet to lose
its viability as a commercial medium. If Internet commerce does not continue
to grow or grows more slowly than expected for any of these reasons, our
business, operating results and financial condition would be materially
adversely affected. Even if the required infrastructure, standards, protocols
or complementary products, services or facilities are developed, we may incur
substantial expenses adapting our solutions to changing or emerging
technologies.
 
RISKS OF RAPID TECHNOLOGICAL CHANGE
 
  The market for our products is marked by rapid technological change,
frequent new product introductions and enhancements, uncertain product life
cycles, changes in client demands and evolving industry standards. New
products based on new technologies or new industry standards can render
existing products obsolete and unmarketable. To succeed, we will need to
enhance our current products and develop new products on a timely basis to
keep pace with technological developments and to satisfy the increasingly
sophisticated requirements of our clients. Internet commerce technology,
particularly IRM technology, is complex and new products and product
enhancements can require long development and testing periods. Any delays in
developing and releasing enhanced or new products could have a material
adverse effect on our business, operating results and financial condition. We
cannot be certain that we will successfully develop and market new products or
new product enhancements that respond to technological change, evolving
industry standards or client requirements.
 
OUR MARKET IS HIGHLY COMPETITIVE
 
  The Internet software market is intensely competitive. Our clients'
requirements and the technology available to satisfy those requirements
continually change. We expect competition to persist and intensify in the
future.
 
  Our principal competitors include: in-house development efforts by potential
clients or partners; other vendors of software that directly address elements
of Internet Relationship Management, such as BroadVision; and developers of
software that address only certain technology components of IRM (e.g., content
management), such as Inso Corporation.
 
  Many of these companies, as well as some other competitors, have longer
operating histories and significantly greater financial, technical, marketing
and other resources than we do. Many of these companies can also leverage
extensive customer bases and adopt aggressive pricing policies to gain market
share. Potential competitors such as Netscape and Microsoft may bundle their
products in a manner that may discourage users from purchasing our products.
In addition, it is possible that new competitors or alliances among
competitors may emerge and rapidly acquire significant market share.
 
  Competitive pressures may make it difficult for us to acquire and retain
clients and may require us to reduce the price of our software. We cannot be
certain that we will be able to compete successfully with existing or
 
                                       7
<PAGE>
 
new competitors. If we fail to compete successfully against current or future
competitors, our business, operating results and financial condition would be
materially adversely affected. See "Business--Competition."
 
POTENTIAL IMPACT OF PRIVACY CONCERNS
 
  Businesses use our StoryServer product to develop and maintain profiles to
tailor the content to be provided to Web site visitors. Typically, the
software captures profile information when consumers, business customers or
employees visit a Web site and volunteer information in response to survey
questions. Usage data collected over time augments the profiles. However,
privacy concerns may nevertheless cause visitors to resist providing the
personal data necessary to support this profiling capability. More
importantly, even the perception of security and privacy concerns, whether or
not valid, may indirectly inhibit market acceptance of our products. In
addition, legislative or regulatory requirements may heighten these concerns
if businesses must notify Web site users that the data captured after visiting
certain Web sites may be used by marketing entities to unilaterally direct
product promotion and advertising to that user. We are not aware of any such
legislation or regulatory requirements currently in effect in the United
States. Certain other countries and political entities, such as the European
Economic Community, have adopted such legislation or regulatory requirements.
The United States may adopt similar legislation or regulatory requirements. If
consumer privacy concerns are not adequately addressed, our business,
financial condition and operating results could be materially adversely
affected.
 
  Our StoryServer product uses "cookies" to track demographic information and
user preferences. A "cookie" is information keyed to a specific server, file
pathway or directory location that is stored on a user's hard drive, possibly
without the user's knowledge (but generally removable by the user). Germany
has imposed laws limiting the use of cookies, and a number of Internet
commentators, advocates and governmental bodies in the United States and other
countries have urged passage of laws limiting or abolishing the use of
cookies. If such laws are passed, our business, operating results and
financial condition could be materially adversely affected.
 
POTENTIAL FOR INCREASING GOVERNMENT REGULATION
 
  As Internet commerce evolves, we expect that federal, state or foreign
agencies will adopt regulations covering issues such as user privacy, pricing,
content and quality of products and services. Although many of these
regulations may not apply to our business directly, we expect that laws
regulating the solicitation, collection or processing of personal/consumer
information could indirectly affect our business. The Telecommunications Act
of 1996 (the "Telecommunications Act") prohibits certain types of information
and content from being transmitted over the Internet. The prohibition's scope
and the liability associated with a Telecommunications Act violation are
currently unsettled. In addition, although substantial portions of the
Communications Decency Act (the "CDA") were held to be unconstitutional, we
cannot be certain that similar legislation will not be enacted and upheld in
the future. It is possible that such legislation could expose companies
involved in Internet commerce to liability, which could limit the growth of
Internet commerce generally. Legislation like the Telecommunications Act and
the CDA could dampen the growth in Web usage and decrease its acceptance as a
communications and commercial medium. If enacted, such laws, rules or
regulations could limit the market for our products and services, which could
materially adversely affect our business, financial condition and operating
results.
 
  The United States government also regulates the export of encryption
technology, which our products incorporate. Current or future export
regulations may limit our ability to distribute our software outside the
United States. Although we take precautions against unlawful export of our
software, we cannot effectively control the unauthorized distribution of
software across the Internet. If our export authority is revoked or modified,
if our software is unlawfully exported or if the United States government
adopts new legislation or regulation restricting export of software and
encryption technology, our business, operating results and financial condition
could be materially adversely affected.
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
  We received 3% and 18% of our total revenue in 1997 and the nine months
ended September 30, 1998, respectively, through licenses and services sold to
clients located outside of the United States. We expect international revenue
to account for a significant percentage of total revenue in the future and we
believe that we must continue to expand our international sales activities in
order to be successful. Our international sales growth will be limited if we
are unable to establish additional foreign operations, expand international
sales channel
 
                                       8
<PAGE>
 
management and support organizations, hire additional personnel, customize
products for local markets, develop relationships with international service
providers and establish relationships with additional distributors and third
party integrators. In that case, our business, operating results and financial
condition could be materially adversely affected. Even if we are able to
successfully expand international operations, we cannot be certain that we
will be able to maintain or increase international market demand for our
products. International operations are generally subject to a number of risks,
including:
 
  . Expenses associated with customizing products for foreign countries;
 
  . Protectionist laws and business practices that favor local competition;
 
  . Dependence on local vendors;
 
  . Multiple, conflicting and changing governmental laws and regulations;
 
  . Longer sales cycles;
 
  . Difficulties in collecting accounts receivable;
 
  . Foreign currency exchange rate fluctuations; and
 
  . Political and economic instability.
 
  To date, a majority of our international revenues and costs have been
denominated in foreign currencies. We believe that an increasing portion of
our international revenues and costs will be denominated in foreign currencies
in the future. To date, we have not engaged in any foreign exchange hedging
transactions and we are therefore subject to foreign currency risk.
 
FAILURE TO PROPERLY MANAGE GROWTH COULD ADVERSELY AFFECT OUR BUSINESS
 
  We have expanded our operations rapidly since inception. We intend to
continue to expand in the foreseeable future to pursue existing and potential
market opportunities. This rapid growth places a significant demand on
management and operational resources. In order to manage growth effectively,
we must implement and improve our operational systems, procedures and controls
on a timely basis. If we fail to implement and improve these systems, our
business, operating results and financial condition will be materially
adversely affected. In addition, we are moving to new headquarters facilities
in December 1998, which we expect will be a disruptive, time consuming and
expensive process.
 
 
LOSS OF KEY PERSONNEL COULD ADVERSELY AFFECT OUR BUSINESS
 
  Our success depends largely on the skills, experience and performance of
some key members of our management. If we lose one or more of these key
employees, our business, operating results and financial condition could be
materially adversely affected. In addition, our future success will depend
largely on our ability to continue attracting and retaining highly skilled
personnel. Like other software companies, we face intense competition for
qualified personnel, particularly in the Austin, Texas area. We cannot be
certain that we will be successful in attracting, assimilating or retaining
qualified personnel in the future. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Management."
 
RISKS ASSOCIATED WITH THE YEAR 2000 PROBLEM
 
  The "Year 2000 Issue" refers generally to the problems that some software
may have in determining the correct century for the year. For example,
software with date-sensitive functions that is not Year 2000 compliant may not
be able to distinguish whether "00" means 1900 or 2000, which may result in
failures or the creation of erroneous results.
 
  We have conducted the first phases of a Year 2000 readiness review for the
current versions of our products. The review includes assessment,
implementation (including remediation, upgrading and replacement of certain
product versions), validation testing, and contingency planning. We continue
to respond to customer questions about prior versions of our products on a
case-by-case basis.
 
  We have largely completed all phases of this plan, except for contingency
planning, for the current versions of our products. As a result, all current
versions of our products are "Year 2000 Compliant," as defined below, when
configured and used in accordance with the related documentation, and provided
that the underlying operating system of the host machine and any other
software used with or in the host machine or our products are also Year 2000
Compliant. We have not tested our products on all platforms or all versions of
operating
 
                                       9
<PAGE>
 
systems that we currently support. The initial release of StoryServer 4
required a patch to fix a minor error in a third-party product included in
StoryServer 4. We have provided the patch on our Web site in order to be Year
2000 Compliant.
 
  We have defined "Year 2000 Compliant" as the ability to:
 
    (i) correctly handle date information needed for the December 31, 1999 to
  January 1, 2000 date change;
 
    (ii) function according to the product documentation provided for this
  date change, without changes in operation resulting from the advent of a
  new century, assuming correct configuration;
 
    (iii) where appropriate, respond to two-digit date input in a way that
  resolves the ambiguity as to century in a disclosed, defined, and
  predetermined manner;
 
    (iv) if the date elements in interfaces and data storage specify the
  century, store and provide output of date information in ways that are
  unambiguous as to century; and
 
    (v) recognize year 2000 as a leap year.
 
  We have tested software obtained from third parties (licensed software,
shareware, and freeware) that is incorporated into our products, and we are
seeking assurances from our vendors that licensed software is Year 2000
Compliant. Despite testing by us and by current and potential clients, and
assurances from developers of products incorporated into our products, our
products may contain undetected errors or defects associated with Year 2000
date functions. Known or unknown errors or defects in our products could
result in delay or loss of revenue, diversion of development resources, damage
to our reputation, or increased service and warranty costs, any of which could
materially adversely affect our business, operating results, or financial
condition. Some commentators have predicted significant litigation regarding
Year 2000 compliance issues, and we are aware of such lawsuits against other
software vendors. Because of the unprecedented nature of such litigation, it
is uncertain whether or to what extent we may be affected by it.
 
  Our internal systems include both our information technology, or IT, and
non-IT systems. We have initiated an assessment of our material internal IT
systems (including both our own software products and third-party software and
hardware technology) but we have not initiated an assessment of our non-IT
systems. We expect to complete testing of our IT systems in 1998. To the
extent that we are not able to test the technology provided by third-party
vendors, we are seeking assurances from vendors that their systems are Year
2000 Compliant. We are not currently aware of any material operational issues
or costs associated with preparing our internal IT and non-IT systems for the
Year 2000. However, we may experience material unanticipated problems and
costs caused by undetected errors or defects in the technology used in our
internal IT and non-IT systems.
 
  We do not currently have any information concerning the Year 2000 compliance
status of our customers. As is the case with other similarly situated software
companies, if our current or future customers fail to achieve Year 2000
compliance or if they divert technology expenditures (especially technology
expenditures that were reserved for enterprise software) to address Year 2000
compliance problems, our business, results of operations, or financial
condition could be materially adversely affected.
 
  We have funded our Year 2000 plan from available cash and have not
separately accounted for these costs in the past. To date, these costs have
not been material. We will incur additional costs related to the Year 2000
plan for administrative personnel to manage the project, outside contractor
assistance, technical support for our products, product engineering and
customer satisfaction. In addition, we may experience material problems and
costs with Year 2000 compliance that could adversely affect our business,
results of operations, and financial condition.
 
  We have not yet fully developed a contingency plan to address situations
that may result if we are unable to achieve Year 2000 readiness of our
critical operations. The cost of developing and implementing such a plan may
itself be material. Finally, we are also subject to external forces that might
generally affect industry and commerce, such as utility or transportation
company Year 2000 compliance failures and related service interruptions.
 
                                      10

RISK OF SOFTWARE DEFECTS; PRODUCT LIABILITY
 
  Complex software products such as ours often contain errors or defects,
particularly when first introduced or when new versions or enhancements are
released. Despite internal testing and testing by current and potential
customers, our current and future products may contain serious defects,
including Year 2000 errors. Serious defects or errors could result in lost
revenues or a delay in market acceptance, which would have a material adverse
effect on our business, operating results and financial condition.
 
  Since our clients use our products for mission critical applications such as
Internet commerce, errors, defects or other performance problems could result
in financial or other damages to our clients. They could seek damages for
losses, which, if successful, could have a material adverse effect on our
business, operating results or financial condition. Although our license
agreements typically contain provisions designed to limit our exposure to
product liability claims, existing or future laws or unfavorable judicial
decisions could negate such limitation of liability provisions. We have not
experienced any product liability claims to date. However, a product liability
claim brought against us, even if not successful, would likely be time
consuming and costly.
 
RELIANCE ON THIRD-PARTY SOFTWARE
 
  We integrate third-party software as a component of our software. The third-
party software may not continue to be available to us on commercially
reasonable terms. For instance, we license GroupLens Express from Net
Perceptions, Inc. for certain personalization functionality in StoryServer 4.
The agreement expires in October 1999, but it is renewed automatically unless
either party gives 60 days notice prior to the renewal date. If we cannot
maintain licenses to key third-party software, such as GroupLens Express,
shipments of our products could be delayed until equivalent software could be
developed or licensed and integrated into our products, which could materially
adversely affect our business, operating results and financial condition. See
"Business--Proprietary Rights and Licensing."
 
RISK OF CHANGES IN ACCOUNTING STANDARDS
 
  The American Institute of Certified Public Accountants issued Statement of
Position 97-2 ("SOP 97-2"), Software Revenue Recognition, in October 1997 and
amended it by Statement of Position 98-4 ("SOP 98-4"). We adopted SOP 97-2 and
SOP 98-4 effective January 1, 1998. We believe our current revenue recognition
policies and practices are materially consistent with SOP 97-2 and SOP 98-4.
However, full implementation guidelines for this standard have not yet been
issued. Once available, our current revenue accounting practices may need to
change and such changes could materially adversely affect our future revenue
and earnings. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
LIMITED PROTECTION OF PROPRIETARY TECHNOLOGY; RISKS OF INFRINGEMENT
 
  In recent years, there has been significant litigation in the United States
involving patents and other intellectual property rights. We are not currently
involved in any intellectual property litigation. We may, however, be a party
to litigation in the future to protect our intellectual property or as a
result of an alleged infringement of other's intellectual property. We rely on
a combination of patent, trademark, trade secret and copyright law and
contractual restrictions to protect our technology. These legal protections
provide only limited protection. If we litigated to enforce our rights, it
would be expensive, divert management resources and may not be adequate to
protect our business.
 
  Others asserting rights against us could force us to defend ourselves or our
clients against alleged infringement of intellectual property rights. We could
incur substantial costs to prosecute or defend any such litigation and
intellectual property litigation could force us to do one or more of the
following:
 
  . Cease selling, incorporating or using products or services that
    incorporate the challenged intellectual property;
 
  . Obtain from the holder of the infringed intellectual property right a
    license to sell or use the relevant technology, which license may not be
    available on reasonable terms; and
 
  . Redesign those products or services that incorporate such technology.

NO PRIOR PUBLIC MARKET FOR THE COMMON STOCK; POTENTIAL VOLATILITY OF STOCK
PRICE
 
  Prior to this offering, you could not buy or sell our Common Stock publicly.
An active public market for our Common Stock may not develop or be sustained
after the offering. Although the initial public offering price was determined
based on several factors, the initial offering price may vary from the market
price after the offering. See "Underwriters." The market price of the Common
Stock may fluctuate significantly in response to a number of factors, some of
which are beyond our control, including:
 
  . Quarterly variations in operating results;
 
  . Changes in financial estimates by securities analysts;
 
  . Changes in market valuations of Internet software companies;
 
  . Announcements by us of significant contracts, acquisitions, strategic
    partnerships, joint ventures or capital commitments;
 
  . Loss of a major client or failure to complete significant license
    transactions;
 
  . Additions or departures of key personnel;
 
  . Future sales of Common Stock; and
 
  . Stock market price and volume fluctuations, which are particularly common
    among highly volatile securities of Internet and software companies.
 
  In the past, securities class action litigation has often been brought
against a company following periods of volatility in the market price of its
securities. We may in the future be the target of similar litigation.
Securities litigation could result in substantial costs and divert
management's attention and resources, which could have a material adverse
effect on our business, operating results and financial condition.
 
FUTURE CAPITAL NEEDS AND UNCERTAIN ADDITIONAL FINANCING
 
  We expect the net proceeds from this offering, cash on hand, cash
equivalents and commercial credit facilities to meet our working capital and
capital expenditure needs for at least the next 12 months. After that, we may
need to raise additional funds and we cannot be certain that we would be able
to obtain additional financing on favorable terms, if at all. Further, if we
issue equity securities, stockholders may experience additional dilution or
the new equity securities may have rights, preferences or privileges senior to
those of existing holders of Common Stock. If we cannot raise funds, if
needed, on acceptable terms, we may not be able to develop or enhance our
products, take advantage of future opportunities or respond to competitive
pressures or unanticipated requirements, which could have a material adverse
effect on our business, operating results and financial condition. See "Use of
Proceeds," "Dilution" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
CONTROL OF COMPANY BY EXISTING STOCKHOLDERS
 
  On completion of this offering, executive officers and directors and their
affiliates will beneficially own, in the aggregate, approximately   % of our
outstanding Common Stock. As a result, these stockholders will be able to
exercise control over all matters requiring stockholder approval, including
the election of directors and approval of significant corporate transactions,
which could delay or prevent someone from acquiring or merging with us. See
"Principal and Selling Stockholders."
 
ANTI-TAKEOVER PROVISIONS
 
  Certain provisions of our Certificate of Incorporation and Bylaws may
discourage, delay or prevent a merger or acquisition that a stockholder may
consider favorable. Such provisions include:
 
  . Authorizing the issuance of "blank check" preferred stock;
 
  . Providing for a classified Board of Directors with staggered, three-year
    terms;
 
  . Prohibiting cumulative voting in the election of directors;
 
  . Requiring super-majority voting to effect certain amendments to our
    Certificate of Incorporation and Bylaws;
 
 
                                      12
<PAGE>
 
  . Limiting the persons who may call special meetings of stockholders;
 
  . Prohibiting stockholder action by written consent; and
 
  . Establishing advance notice requirements for nominations for election to
    the Board of Directors or for proposing matters that can be acted on by
    stockholders at stockholder meetings.
 
  Certain provisions of Delaware law and our stock incentive plans may also
discourage, delay or prevent someone from acquiring or merging with us. See
"Management--Employee Benefit Plans" and "Description of Capital Stock--Anti-
takeover Effects of Provisions of the Certificate of Incorporation, Bylaws and
Delaware Law."
 
POTENTIAL EFFECT OF SHARES COMING AVAILABLE FOR FUTURE SALE
 
  Sales of a substantial number of shares of Common Stock after the offering
could adversely affect the market price of the Common Stock and could impair
our ability to raise capital through the sale of additional equity securities.
On completion of this offering, we will have     shares of Common Stock
outstanding or subject to currently exercisable options (    shares if the
Underwriters over-allotment option is exercised in full). The     shares sold
in this offering (    shares if the Underwriter's over-allotment option is
exercised in full) will be freely tradable without restriction or further
registration under the Federal securities laws unless purchased by
"affiliates" of the Company as that term is defined in Rule 144. The remaining
11,476,133 shares of Common Stock outstanding on completion of the offering
will be "restricted securities" as that term is defined in Rule 144.
 
  Stockholders holding more than  % of the outstanding Common Stock and
currently exercisable options to purchase Common Stock have executed lock-up
agreements that limit their ability to sell Common Stock. These stockholders
have agreed not to sell or otherwise dispose of any shares of Common Stock for
a period of at least 180 days after the date of this Prospectus without the
prior written approval of Morgan Stanley & Co. Incorporated. When the lock-up
agreements expire, these shares and the shares underlying the options will
become eligible for sale, in some cases only pursuant to the volume, manner of
sale and notice requirements of Rule 144. See "Management--Employee Benefits
Plans" and "Shares Eligible for Future Sale."
 
IMMEDIATE SUBSTANTIAL DILUTION
 
  The initial public offering price is expected to be substantially higher
than the book value per share of the outstanding Common Stock. As a result,
investors purchasing Common Stock in this offering will incur immediate
substantial dilution. In addition, we have issued options to acquire Common
Stock at prices significantly below the initial public offering price. To the
extent such outstanding options are ultimately exercised, there will be
further dilution to investors in this offering. See "Dilution."
 
               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
  Some of the statements under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business," and elsewhere in this Prospectus constitute forward-
looking statements. These statements involve known and unknown risks,
uncertainties, and other factors that may cause our or our industry's actual
results, levels of activity, performance, or achievements to be materially
different from any future results, levels of activity, performance, or
achievements expressed or implied by such forward-looking statements. Such
factors include, among other things, those listed under "Risk Factors" and
elsewhere in this Prospectus.
 
  In some cases, you can identify forward-looking statements by terminology
such as "may," "will," "should," "expects," "plans," "anticipates,"
"believes," "estimates," "predicts," "potential," or "continue" or the
negative of such terms or other comparable terminology.
 
  Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance, or achievements. Moreover, neither we nor any other
person assumes responsibility for the accuracy and completeness of such
statements. We are under no duty to update any of the forward-looking
statements after the date of this Prospectus to conform such statements to
actual results.

                                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 $
million ($    million if the Underwriters' over-allotment option is exercised
in full), at an assumed initial public offering price of $    share and after
deducting estimated offering expenses of $    and underwriting discounts and
commissions payable by the Company. The Company will not receive any of the
proceeds from the sale of shares of Common Stock by the Selling Stockholders.
The primary purposes of this offering are to obtain additional working
capital, create a public market for the Company's Common Stock, facilitate
future access by the Company to public capital markets and provide liquidity
to existing stockholders.
 
  The Company intends to use the proceeds of the offering received by it for
working capital and general corporate purposes. Although the Company may use a
portion of the net proceeds to acquire technology or businesses that are
complementary to the Company's business, there are no current plans in this
regard. Pending such uses, the Company plans to invest the net proceeds in
short-term, interest-bearing, investment grade securities.
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid any cash dividends on its Common
Stock or other securities and does not anticipate paying cash dividends in the
foreseeable future. The Company's lines of credit currently prohibit the
payment of dividends.

                                CAPITALIZATION
 
  Unless otherwise specifically stated, the information in this Prospectus has
been adjusted to reflect the conversion of all outstanding shares of Preferred
Stock into Common Stock on the completion of the offering, but does not take
into account the possible issuance of additional shares of Common Stock to the
underwriters pursuant to their right to purchase additional shares to cover
overallotments.
 
  The following table sets forth the capitalization of the Company as of
September 30, 1998, (i) on an actual basis; (ii) on a pro forma basis to
reflect (A) the filing of an amendment to the Company's Amended and Restated
Certificate of Incorporation to provide for authorized capital stock of
80,000,000 shares of Common Stock and 10,000,000 shares of undesignated
Preferred Stock and (B) the conversion of all shares of Preferred Stock
outstanding as of September 30, 1998 into 8,098,872 shares of Common Stock on
completion of this offering; and (iii) on a pro forma as adjusted basis to
reflect the sale of the shares of Common Stock offered by the Company hereby
(assuming an initial public offering price of $   per share) and the
application of the net proceeds therefrom. See "Use of Proceeds." This table
should be read in conjunction with "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the Consolidated Financial
Statements and the Notes thereto.

                                   DILUTION
 
  The pro forma net tangible book value of the Company's Common Stock as of
September 30, 1998, giving effect to the conversion of all shares of Preferred
Stock outstanding as of September 30, 1998 into Common Stock on the closing of
this offering, was $4,552,000, or approximately $.42 per share. "Pro forma net
tangible book value" per share represents the amount of total tangible assets
of the Company less total liabilities, divided by 10,960,950 shares of Common
Stock outstanding after giving effect to the conversion of the Preferred Stock
outstanding as of September 30, 1998 into Common Stock. After giving effect to
the issuance and sale of     shares of Common Stock offered by the Company
(based on an assumed initial public offering price of $    per share and after
deducting estimated underwriting discounts and commissions and estimated
offering expenses payable by the Company), the pro forma net tangible book
value of the Company as of September 30, 1998 would have been $   , or $
per share. This represents an immediate increase in pro forma net tangible
book value of $    per share to existing stockholders and an immediate
dilution in net tangible book value of $    per share to new investors.
Investors participating in this offering will incur immediate, substantial
dilution. The following table illustrates the per share dilution:

Stock at $16.33 per share and, on December 3, 1998, reserved 45,926 shares of
Common Stock for issuance on exercise of warrants issued on that date at an

OVERVIEW
 
  Vignette is a leading global provider of Internet Relationship Management
software products and services, a new category of enterprise solutions
designed to enable businesses to build sustainable online customer
relationships, increase the returns on their Internet-related investments and
capitalize on Internet business opportunities. The Company was founded in
December 1995. From December 1995 through December 1996, Vignette devoted its
efforts principally to raising capital, research and development activities,
and establishing markets for its products. As a result, the Company was
considered a "development stage enterprise" during this period. Beginning in
January 1997, the Company actively began selling its products. To date,
Vignette has developed and released several versions of its StoryServer
product and has sold its products and services to over 160 clients. The
Company markets and sells its products worldwide primarily through its direct
sales force. The Company has its principal office in Austin, Texas and also
has offices in Atlanta, Georgia; Boston, Massachusetts; Chicago, Illinois;
Dallas, Texas; Newport Beach, California; New York, New York; San Mateo,
California; Valencia, California; Hamburg, Germany; London, England; and
Sydney, Australia.
 
  The Company derives its revenue from the sale of software product licenses
and from professional consulting, maintenance and support services. Product
license revenue is recognized when persuasive evidence of an agreement exists,
the product has been delivered, no significant Company obligations with regard
to implementation remain, the license fee is fixed or determinable and
collection of the fee is probable. Services revenue consists of fees from
professional services and from maintenance and telephone support. Professional
services include integration of software, application development, training
and software installation. Professional services fees are billed either on a
time and materials basis or on a fixed-price schedule. Professional services
fees billed on a time and materials basis are recognized as the services are
performed. The Company recognizes professional services fees on fixed-price
service arrangements on the completion of specific contractual milestone
events, or based on an estimated percentage of completion as work progresses.
Maintenance agreements are typically purchased annually and are priced based
on a percentage of the product license fee. Telephone support is priced based
on differing levels of support. Clients purchasing maintenance agreements
receive unspecified product upgrades and electronic, Web-based technical
support, while purchasers of support contracts receive additional telephone
support. Revenue from maintenance and support agreements is recognized ratably
over the term of the agreement, typically one year. Cash receipts from clients
and billed amounts due from clients in excess of revenue recognized are
recorded as deferred revenue. The timing and amount of cash receipts from
clients can vary significantly depending on specific contract terms and can
therefore have a significant impact on the amount of deferred revenue in any
given period.
 
  Cost of revenue consists of costs to manufacture, package and distribute the
Company's products and related documentation, as well as personnel and other
expenses related to providing professional services. Since its inception, the
Company has incurred substantial costs to develop its technology and products,
to recruit and train personnel for its engineering, sales and marketing and
professional services departments, and to establish an administrative
organization. As a result, the Company has incurred net losses in each fiscal
quarter since inception and, as of September 30, 1998, had an accumulated
deficit of $27.4 million. The Company anticipates that its operating expenses
will increase substantially in future quarters as it increases sales and
marketing operations, develops new distribution channels, funds greater levels
of research and development, broadens professional services and support, and
improves operational and financial systems. Accordingly, the Company expects
to incur additional losses for the foreseeable future. In addition, the
Company's limited operating history makes the prediction of future results of
operations difficult and, accordingly, there can be no assurance that the
Company will achieve or sustain revenue growth or profitability.
 
 
                                      18
<PAGE>
 
  The Company had 219 full-time employees at September 30, 1998, up from 79
and 26 at December 31, 1997 and 1996, respectively. This rapid growth places a
significant demand on the Company's management and operational resources. In
order to manage growth effectively, the Company must implement and improve its
operational systems, procedures and controls on a timely basis. In addition,
the Company expects that future expansion will continue to challenge the
Company's ability to hire, train, motivate, and manage its employees.
Competition is intense for highly qualified technical, sales and marketing and
management personnel. If the Company's total revenue does not increase
relative to its operating expenses, the Company's management systems do not
expand to meet increasing demands, the Company fails to attract, assimilate
and retain qualified personnel, or the Company's management otherwise fails to
manage the Company's expansion effectively, there would be a material adverse
effect on the Company's business, financial condition and operating results.
 
RESULTS OF OPERATIONS
 
  REVENUE
 
  Total revenue increased from $1.7 million for the nine months ended
September 30, 1997 to $9.5 million for the nine months ended September 30,
1998. This increase was attributable to an increase in the Company's client
base resulting in substantial growth in product license and services revenue.
No one client accounted for greater than 10% of total revenue during the nine
months ended September 30, 1997 and 1998. The Company's total revenue in 1997
was $3.0 million. Two clients accounted for 24% of total revenue in 1997. The
Company did not have any revenue in 1996, as the Company was in the
development stage.
 
  Product License. Product license revenue increased from $1.2 million for the
nine months ended September 30, 1997 to $5.2 million for the nine months ended
September 30, 1998, representing 69% and 54% of total revenue, respectively.
The increase in product license revenue in absolute dollars was due primarily
to an increase in the number of clients resulting from growing market
acceptance of the Company's StoryServer product after the release of
StoryServer 3 in September 1997. Product license revenue decreased as a
percentage of total revenue due to the increase in services revenue during the
same period. The Company first began shipping its products in January 1997.
Product license revenue was $1.9 million in 1997, representing 64% of total
revenue in 1997.
 
  Services. Services revenue increased from $537,000 for the nine months ended
September 30, 1997 to $4.4 million for the nine months ended September 30,
1998, representing 31% and 46% of total revenue, respectively. Services
revenue from professional services fees increased from $479,000 for the nine
months ended September 30, 1997 to $3.5 million for the nine months ended
September 30, 1998. Services revenue from maintenance and support agreements
increased from $58,000 for the nine months ended September 30, 1997 to
$841,000 for the nine months ended September 30, 1998. The increase in all
types of services revenue was due primarily to an increase in the number of
clients and sale of product licenses, which generally include or lead to
contracts to perform professional services and purchases of software
maintenance and technical support service agreements. In 1997, the Company
recognized $1.1 million in services revenue, representing 36% of total
revenue. Of this amount, professional services fees accounted for $941,000 and
maintenance and support agreements accounted for $140,000.
 
  The Company expects that professional services-related revenue will increase
in absolute dollars in the future to the extent that additional clients
license the Company's products and as the Company expands both its capacity
for the delivery of professional services as well as the scope of its
professional services offerings. The Company expects that services revenue
from maintenance and support agreements will increase in absolute dollars in
the future due to the maintenance components of new and existing license
agreements.
 
  COST OF REVENUE
 
  Product License. Product license costs consist of expenses incurred by the
Company to manufacture, package and distribute its products and related
documentation and costs of licensing third-party software incorporated in its
products. Product license costs increased from $24,000 for the nine months
ended September 30, 1997 to $510,000 for the nine months ended September 30,
1998, representing 2% and 10% of product license revenue, respectively. The
increase in absolute dollars and as a percentage of product license revenue
during the nine months ended
 
                                      19
<PAGE>
 
September 30, 1998 was primarily attributable to the Company entering into an
OEM license with Net Perceptions for its GroupLens Express software that
allows the Company to embed certain personalization functionality into
StoryServer. Product license costs were $37,000 in 1997, representing 2% of
product license revenue. The Company expects product license costs to increase
in the future in absolute dollar terms due to additional clients licensing the
Company's products and the Company acquiring OEM licenses to third party
technology that it may choose to embed in its product offerings.
 
  Services. Services costs include salary expense and other related costs for
the Company's professional service, maintenance and telephone support staffs,
as well as third-party contractor expenses. Services costs increased from
$674,000 for the nine months ended September 30, 1997 to $5.6 million for the
nine months ended September 30, 1998, representing 126% and 128% of services
revenue, respectively. The increase in dollar amount was primarily due to
startup costs incurred in connection with beginning and expanding the
Company's professional services organization, and to a lesser extent, the
increase in the number of product license clients, which generally require
professional services provided by the Company. To date, the Company's services
costs have been significantly higher than its services revenue, and the
Company expects that trend to continue for the foreseeable future as the
Company continues to expand its professional services organization. Services
costs related to professional services increased from $630,000 for the nine
months ended September 30, 1997 to $5.3 million for the nine months ended
September 30, 1998, representing 132% and 149% of professional services-
related revenue. Services costs related to maintenance and support agreements
increased from $44,000 for the nine months ended September 30, 1997 to
$328,000 for the nine months ended September 30, 1998. Services costs were
$1.4 million in 1997, representing 133% of services revenue, substantially all
of which were amounts associated with professional services.
 
  The Company expects services costs to increase in the future in absolute
dollars to the extent that the Company continues to generate new clients and
associated product license and services revenue. Services costs as a
percentage of services revenue can be expected to vary significantly from
period to period depending on the mix of services provided by the Company,
whether such services are provided by the Company or third-party contractors,
and overall utilization rates.
 
  OPERATING EXPENSES
 
  Research and Development. Research and development expenses consist
primarily of personnel costs to support product development. Research and
development expenses increased from $1.9 million for the nine months ended
September 30, 1997 to $4.8 million for the nine months ended September 30,
1998, representing 111% and 51% of total revenue, respectively. Research and
development expenses increased from $892,000 in 1996 to $2.9 million in 1997.
The increase in absolute dollars in these periods was due to increases in
internal engineering personnel.
 
  The Company believes that continued investment in research and development
is critical to attaining its strategic objectives, and, as a result, expects
research and development expenses to increase significantly in absolute
dollars in future periods. To date, all software development costs have been
expensed in the period incurred.
 
  Sales and Marketing. Sales and marketing expenses consist primarily of
salaries and other related costs for sales and marketing personnel, sales
commissions, travel, public relations and marketing materials and tradeshows.
Sales and marketing expenses increased from $2.9 million for the nine months
ended September 30, 1997 to $9.4 million for the nine months ended September
30, 1998, representing 167% and 99% of total revenue, respectively. The
increase in absolute dollars was due to a significant increase in sales and
marketing personnel and the Company's increased marketing program
expenditures.
 
  Sales and marketing expenses increased from $428,000 in 1996 to $5.0 million
in 1997. The increase was due to a substantial increase in sales and marketing
personnel and the commencement of the sales and marketing of the Company's
products in January 1997.
 
  The Company believes these expenses will continue to increase in future
periods as it expects to continue to expand its sales and marketing efforts.
The Company also anticipates that sales and marketing expenses may fluctuate
as a percentage of total revenue from period to period as new sales personnel
are hired and begin to achieve productivity.
 
                                      20
<PAGE>
 
  General and Administrative. General and administrative expenses consist
primarily of salaries and other related costs for operations and finance
employees, legal and accounting services and certain facilities-related
expenses. General and administrative expenses increased from $718,000 for the
nine months ended September 30, 1997 to $3.5 million for the nine months ended
September 30, 1998, representing 42% and 36% of total revenue, respectively.
General and administrative expenses increased from $503,000 in 1996 to $1.3
million in 1997. The increase in absolute dollars for these periods was due to
increased personnel and facility expenses necessary to support the Company's
expanding operations and, to a lesser extent, costs related to the
establishment of European operations in November 1997.
 
  The Company believes general and administrative expenses will increase in
absolute dollars as the Company expects to add personnel to support its
expanding operations, incur additional costs related to the growth of its
business, and assume the responsibilities of a public company.
 
  Write-Off of Acquired In-Process Research and Development. During May 1998,
the Company acquired from RandomNoise, Inc. certain in-process research and
development effort, a developed product and an insignificant amount of
equipment in exchange for 191,022 shares of the Company's Series G Convertible
Preferred Stock valued at $2.0 million and for $100,000 in cash. The in-
process research and development effort related to the development of a visual
development tool using graphical user interface ("GUI") technology not
possessed by the Company. The results of the in-process research and
development effort at the time of purchase had not progressed to a stage where
they met technological feasibility as they lacked many key elements including:
the ability to integrate with database oriented dynamic publishing systems;
database interfacing capabilities; enhanced and consistent application
performance; memory requirements consistent with those of the Company's other
products; multiple Internet browser recognition capabilities; standardized
documentation; and automated testing capabilities. The Company believes that
the acquisition of the in-process research and development effort
significantly accelerated the development of a new GUI-based technology tool,
the beta version of which is expected to be released in February 1999.
Substantially all of the $2.1 million purchase price was allocated to the
acquired in-process research and development effort based upon the following:
the Company assigned no value to the developed product as the Company does not
intend to sell, support or enhance such product and the Company believes it
has no alternative future use; the $2.0 million value ascribed to the 191,022
shares of the Company's Series G Convertible Preferred Stock was based on the
value per share received from the issuance of Series F Redeemable Convertible
Preferred Stock, which occurred in April 1998; and further, the allocation of
the entire $2.1 million purchase price was determined to be reasonable based
on the Company's estimate of costs it would incur if it had performed this
effort internally.
 
  During July 1996, the Company acquired from CNET certain software related to
intellectual property rights for 1,865,000 shares of the Company's Series C
Convertible Preferred Stock valued at approximately $1.9 million. The
technology purchased from CNET lacked many key elements essential to the
ultimate product to be released by the Company, such as an enhanced user
interface, expansion to additional database platforms, an automated install
feature, and automated testing capabilities. The Company incurred significant
costs to complete the key elements and the beta version of the product, which
was released in December 1996. All of the approximately $1.9 million purchase
price was allocated to acquired in-process research and development efforts.
 
  Amortization of Deferred Stock Compensation. In 1998, the Company recorded
total deferred stock compensation of $524,000 in connection with stock options
granted during 1998. Such amount is being amortized over the vesting periods
of the applicable options, resulting in amortization of $142,000 for the nine
months ended September 30, 1998. These amounts represent the difference
between the exercise price of certain stock option grants and the deemed fair
value of the Company's Common Stock at the time of such grants.
 
  OTHER INCOME, NET
 
  Other income, net consists of interest income and expense and gain or loss
on disposals of equipment. Other income, net increased from $88,000 for the
nine months ended September 30, 1997 to $204,000 for the nine months ended
September 30, 1998. The increase was due to increased interest income earned
from cash balances on hand, partially offset by loss on disposals of equipment
and increased interest expense for the period. Other income net increased from
$62,000 in 1996 to $169,000 in 1997. The increase was due to increased
interest income earned from cash balances on hand, partially offset by loss on
disposals of equipment and increased
 
                                      21
<PAGE>
 
interest expense for the period. Proceeds from the private sale of equity
securities in 1997 and in the nine months ended September 30, 1998 caused cash
and short-term investment balances in these periods to be higher than the
comparable prior periods.
 
QUARTERLY RESULTS
 
  The following tables set forth certain unaudited consolidated statements of
operations data both in absolute dollars and as a percentage of total revenue
for each of the Company's last seven quarters. This data has been derived from

same basis as the annual audited consolidated financial statements and, in the
opinion of the Company, include all adjustments (consisting only of normal
recurring adjustments) necessary for a fair presentation of such information.
These unaudited quarterly results should be read in conjunction with the
consolidated financial statements and notes thereto appearing elsewhere in the
Prospectus. The consolidated results of operations for any quarter are not
necessarily indicative of the results for any future period.

</TABLE>
 
  The Company's total revenue has increased in each quarter following
commercial release of its StoryServer software in January 1997. The increase
in each quarter is due to the increase in the number of customers resulting
 
                                      22
<PAGE>
 
from increased market awareness and acceptance of the Company's software,
expansion of the Company's sales organization, including the establishment of
European sales operations in November 1997, and increased maintenance and
support and service revenues reflecting the growth in the installed base of
product licenses.
 
  Cost of revenue has increased each quarter in conjunction with the Company's
increases in total revenue. Product license costs were higher in the quarters
ended June 30, 1998 and September 30, 1998 primarily due to the Company
entering into an OEM license with Net Perceptions in the quarter ended June
30, 1998. Services costs increased during the quarter ended December 31, 1997
due to increased services performed by Vignette staff and increased usage of
third-party consultants. Services costs increased during the quarters ended
June 30, 1998 and September 30, 1998 due to increased usage of third-party
consultants and salaries and related costs for increased professional service
personnel in each period.
 
  Operating expenses have generally increased in absolute dollars each quarter
as the Company has increased staffing in sales and marketing, product
development and general and administrative functions. During the quarter ended
June 30, 1998, the Company purchased in-process research and development from
RandomNoise for $2.1 million, which was immediately expensed to acquired in-
process research and development. Sales and marketing expenses increased in
the quarter ended December 31, 1997 due to the sales staff achieving sales
quotas for the year ended 1997, which resulted in sales commissions and
incentives being paid in the fourth quarter. Sales and marketing expenses
increased during the quarter ended June 30, 1998 due to increased travel and
presales costs in conjunction with increased client sales efforts in the
period, costs incurred for the recruitment of additional sales and marketing
staff and increases in sales and marketing personnel. Sales and marketing
expenses increased during the quarter ended September 30, 1998 due to
increases in sales and marketing personnel and the Company's increased
marketing program expenditures.
 
  As a result of its limited operating history, the Company cannot forecast
operating expenses based on historical results. Accordingly, the Company bases
its expenses in part on future revenue projections. Most of these expenses are
fixed in the short term and the Company may not be able to quickly reduce
spending if revenues are lower than the Company has projected. The Company's
ability to forecast accurately its quarterly revenue is limited due to the
long sales cycle of its software products, which makes it difficult to predict
the quarter in which license sales will occur, and the variability of client
demand for professional services. The Company would expect its business,
operating results and financial condition to be materially adversely affected
if revenues do not meet projections and that net losses in a given quarter
would be even greater than expected.
 
  The Company expects its revenues and operating results may vary
significantly from quarter to quarter. A number of factors are likely to cause
these variations, including:
 
  . Demand for the Company's products and services;
 
  . The timing of sales of the Company's products and services;
 
  . Unexpected delays in introducing new products and services;
 
  . Increased expenses, whether related to sales and marketing, product
    development or administration;
 
  . Changes in the rapidly evolving market for IRM solutions;
 
  . The mix of product license and services revenue, as well as the mix of
    products licensed;
 
  . The mix of domestic and international sales; and
 
  . Costs related to possible acquisitions of technology or businesses.
 
  Accordingly, the Company believes that quarter-to-quarter comparisons of its
operating results are not necessarily meaningful. Investors should not rely on
the results of one quarter as an indication of future performance.
 
  The Company plans to increase its operating expenses to expand sales and
marketing operations, develop new distribution channels, fund greater levels
of research and development, broaden professional services and support and
improve operational and financial systems. If the Company's revenues do not
increase along with these expenses, its business, operating results or
financial condition could be materially adversely affected and net losses in a
given quarter would be even greater than expected.
 
                                      23
<PAGE>
 
  Although it has a limited operating history, the Company believes that
quarterly operating results may experience seasonal fluctuations. For
instance, quarterly results may fluctuate based on client calendar year
budgeting cycles, slow summer purchasing patterns in Europe and the Company's
compensation policies that tend to compensate sales personnel, typically in
the latter half of the year, for achieving annual quotas.
 
NET OPERATING LOSSES AND TAX CREDIT CARRYFORWARDS
 
  As of September 30, 1998, the Company had net operating loss and research
and development carryforwards of approximately $22.8 million and $352,000,
respectively. The net operating loss and credit carryforwards will expire at
various dates, beginning 2011, if not utilized. The Tax Reform Act of 1986
imposes substantial restrictions on the utilization of net operating losses
and tax credits in the event of an "ownership change" of a corporation. The
Company's ability to utilize net operating loss carryforwards on an annual
basis will be limited as a result of a prior "ownership change" in connection
with private sales of equity securities. The Company has provided a full
valuation allowance on the deferred tax asset because of the uncertainty
regarding its realization. The Company's accounting for deferred taxes under
Statement of Financial Accounting Standards No. 109 involves the evaluation of
a number of factors concerning the realizability of the Company's deferred tax
assets. In concluding that a full valuation allowance was required, management
primarily considered such factors as the Company's history of operating losses
and expected future losses and the nature of the Company's deferred tax
assets. See Note 6 of Notes to Consolidated Financial Statements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since its inception, the Company has funded its operations and met its
capital expenditure requirements through the private sale of equity
securities, totaling $27.7 million, net through September 30, 1998. Cash used
in operating activities was $1.5 million, $4.9 million, and $9.7 million in
1996, 1997, and the nine months ended September 30, 1998, respectively.
 
  To date, the Company's investing activities have consisted primarily of
capital expenditures totaling $318,000, $694,000 and $1.0 million in 1996,
1997, and the nine months ended September 30, 1998, respectively, to acquire
property and equipment, mainly computer hardware and software, for the
Company's growing employee base. The Company expects that its capital
expenditures will increase as the Company's employee base grows. At September
30, 1998, the Company did not have any material commitments for capital
expenditures.
 
  At September 30, 1998, the Company had $12.4 million in cash and cash
equivalents and $5.5 million in working capital. Net cash provided by
financing activities in 1996, 1997 and the first nine months of 1998 were $3.7
million, $10.6 million and $16.3 million, respectively. The Company has a $3.0
million revolving line of credit and a $2.0 million equipment line of credit
with Imperial Bank that each bear interest at the bank's prime rate plus
0.75%. At September 30, 1998, $1.5 million and $1.2 million are outstanding
under the revolving and equipment lines of credit, respectively. The Company's
lines of credit are secured by all of its tangible and intangible personal
property. The Company is currently in compliance with all related financial
covenants and restrictions.
 
  On November 30, 1998, the Company completed the sale of 520,516 shares of
Series H Preferred Stock at a price of $16.33 per share for aggregate
consideration of approximately $8,500,000. The Series H Preferred Stock is
convertible into 520,516 shares of Common Stock upon completion of this
offering, subject to adjustment upwards under certain provisions of the
Company's Fourth Amended and Restated Certificate of Incorporation.
 
  In addition, on December 3, 1998, the Company entered into agreements with
Comdisco, Inc. providing for available credit of up to $5 million over a
period of 36 months at an interest rate of 12% per year, an equipment lease
line of $1.25 million and the issuance to Comdisco, Inc. of warrants to
purchase 45,926 shares of Series H Preferred Stock at an exercise price of
$16.33 per share. The line of credit with Comdisco, Inc. is secured by
receivables, equipment, fixtures, inventory and all other tangible property of
the Company and is subordinated to the Company's indebtedness to Imperial
Bank. The warrants will expire three years from the date of this offering.
 
                                      24
<PAGE>
 
In addition, Comdisco, Inc. has the right to purchase additional warrants in
the event the Company increases its equipment lease line or fails to repay its
credit line by the maturity date.
 
  The Company believes that the net proceeds of this offering, together with
cash on hand, cash equivalents, short-term investments and commercial credit
facilities will be sufficient to meet its working capital requirements for at
least the next 12 months. Thereafter, the Company may require additional funds
to support its working capital requirements or for other purposes and may seek
to raise such additional funds through public or private equity financings or
from other sources. There can be no assurance that additional financing will
be available at all or that, if available, such financing will be obtainable
on terms favorable to the Company or that any additional financing will not be
dilutive.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
  As of January 1, 1998, the Company has adopted Statement of Position 97-2,
Software Revenue Recognition ("SOP 97-2"), and SOP 98-4, Deferral of the
Effective Date of SOP 97-2, Software Revenue Recognition ("SOP 98-4"). SOP 97-
2 and SOP 98-4 provide guidance for recognizing revenue on software
transactions and supercede SOP 91-1. The adoption of SOP 97-2 and SOP 98-4 did
not have a material impact on the Company's financial results. However, full
implementation guidelines for this standard have not yet been issued. Once
available, our current revenue accounting practices may need to change and
such changes could affect our future revenue and earnings. Effective January
1, 1998, the Company adopted Statement of Financial Accounting Standard No.
130, Reporting Comprehensive Income (SFAS 130). SFAS 130 requires disclosures
of total non-stockholder changes in equity in interim periods and additional
disclosures of components of non-stockholder changes in equity on an annual
basis. See Note 2 of Notes to the Consolidated Financial Statements. In June
1997, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 131, Disclosures about Segments of an Enterprise and
Related Information (SFAS 131). SFAS 131 is effective for the year ended
December 31, 1998. The Company expects that the implementation of this
standard will not have a material effect on its financial disclosures.
 
YEAR 2000 COMPLIANCE
 
  The "Year 2000 Issue" refers generally to the problems that some software
may have in determining the correct century for the year. For example,
software with date-sensitive functions that is not Year 2000 compliant may not
be able to distinguish whether "00" means 1900 or 2000, which may result in
failures or the creation of erroneous results.
 
  The Company has conducted the first phases of a Year 2000 readiness review
for the current versions of its products. The review includes assessment,
implementation (including remediation, upgrading and replacement of certain
product versions), validation testing, and contingency planning. The Company
continues to respond to customer questions about prior versions of its
products on a case-by-case basis.
 
  Vignette has largely completed all phases of its plan, except for
contingency planning, with respect to the current versions of all of its
products. As a result, the current versions of each of its products are "Year
2000 Compliant," as defined below, when configured and used in accordance with
the related documentation, and provided that the underlying operating system
of the host machine and any other software used with or in the host machine or
the Company's products are also Year 2000 Compliant. The initial release of
StoryServer 4 required a patch to fix a minor error in a third-party product
included in StoryServer 4. The Company has provided the patch on its Web site
in order to be Year 2000 Compliant.
 
  The Company has defined "Year 2000 Compliant" as the ability to: (i)
correctly handle date information needed for the December 31, 1999 to January
1, 2000 date change; (ii) function according to the product documentation
provided for this date change, without changes in operation resulting from the
advent of a new century, assuming correct configuration; (iii) where
appropriate, respond to two-digit date input in a way that resolves the
ambiguity as to century in a disclosed, defined, and predetermined manner;
(iv) if the date elements in interfaces and data storage specify the century,
store and provide output of date information in ways that are unambiguous as
to century; and (v) recognize year 2000 as a leap year. The Company has not
tested its products on all platforms or all versions of operating systems that
it currently supports.
 
  The Company has tested software obtained from third parties (licensed
software, shareware, and freeware) that is incorporated into its products, and
is seeking assurances from its vendors that licensed software is Year
 
                                      25
<PAGE>
 
2000 Compliant. Despite testing by Vignette and current and potential clients,
and assurances from developers of products incorporated into its products, the
Company's products may contain undetected errors or defects associated with
Year 2000 date functions. Known or unknown errors or defects in the Company's
products could result in delay or loss of revenue, diversion of development
resources, damage to the Company's reputation, or increased service and
warranty costs, any of which could materially adversely affect the Company's
business, operating results, or financial condition. Some commentators have
predicted significant litigation regarding Year 2000 compliance issues, and
the Company is aware of such lawsuits against other software vendors. Because
of the unprecedented nature of such litigation, it is uncertain whether or to
what extent the Company may be affected by it.
 
  Vignette's internal systems include both its information technology ("IT")
and non-IT systems. The Company has initiated an assessment of its material
internal IT systems (including both its own software products and third-party
software and hardware technology) but has not initiated an assessment of its
non-IT systems. The Company expects to complete testing of its IT systems in
1998. To the extent that the Company is not able to test the technology
provided by third-party vendors, the Company is seeking assurances from such
vendors that their systems are Year 2000 Compliant. Although the Company is
not currently aware of any material operational issues or costs associated
with preparing its internal IT and non-IT systems for the Year 2000, the
Company may experience material unanticipated problems and costs caused by
undetected errors or defects in the technology used in its internal IT and
non-IT systems.
 
  Vignette does not currently have any information concerning the Year 2000
compliance status of its customers. As is the case with other similarly
situated software companies, if the Company's current or future customers fail
to achieve Year 2000 compliance or if they divert technology expenditures
(especially technology expenditures that were reserved for enterprise
software) to address Year 2000 compliance problems, the Company's business,
results of operations or financial condition could be materially adversely
affected.
 
  The Company has funded its Year 2000 plan from available cash and has not
separately accounted for these costs in the past. To date, these costs have
not been material. The Company will incur additional costs related to the Year
2000 plan for administrative personnel to manage the project, outside
contractor assistance, technical support for its products, product engineering
and customer satisfaction. The Company may experience material problems and
costs with Year 2000 compliance that could adversely affect its business,
results of operations and financial condition.
 
  The Company has not yet fully developed a contingency plan to address
situations that may result if the Company is unable to achieve Year 2000
readiness of its critical operations. The cost of developing and implementing
such a plan may itself be material. Finally, the Company is also subject to
external forces that might generally affect industry and commerce, such as
utility or transportation company Year 2000 compliance failures and related
service interruptions.

INDUSTRY BACKGROUND
 
  The emergence and acceptance of the Internet and the World Wide Web has
fundamentally changed the way that consumers and businesses communicate,
obtain information, purchase goods and transact business. International Data
Corporation ("IDC") estimates that the number of Internet users worldwide will
 
                                      27
<PAGE>
 
grow from approximately 69 million in 1997 to 320 million in 2002. IDC also
estimates that revenue generated from Internet commerce will exceed $400
billion by 2002. As the Internet has become more accessible, functional and
widely used, it has emerged as a primary business channel alongside the
telephone, paper-based communication and face-to-face interaction. For
instance, businesses are increasingly using the Web as both a marketing tool
and distribution channel to communicate and conduct business with partners,
customers and employees.
 
  Origins of Online Business
 
  The growth in the number of Internet users, as well as the open nature of
the Internet, has led many businesses to seek new ways to take advantage of
this global platform. The earliest business use of the Internet was the
creation of informational Web sites, which typically involved merely
reformatting existing marketing materials to create an online brochure. This
simple use of the Internet to present static information was quickly
supplanted by the first generation of electronic commerce businesses. The
introduction of new technology enabled businesses to create Web sites for
online publishing, which were financed by advertising, and electronic catalog
businesses where hard goods such as books or computers could be sold. These
Internet businesses focused on developing a basic advertising and transaction
infrastructure rather than capitalizing on the unique aspects of Internet
commerce. In addition, these first generation online businesses were based on
traditional, physical world business models and were differentiated only by
wider selection and lower prices. Success for these businesses was measured by
the total amount of Web site traffic.
 
  Advertising- and transaction-based Internet business models have been
successful in generating online transactions. However, as the number of
companies attempting to conduct business online has increased, the Web has
become a highly competitive business environment in which customers have a
large number of easily accessible choices, eroding customer loyalty. As a
result, it is becoming increasingly difficult for businesses on the Internet
to reach their target audiences, build customer loyalty and differentiate
themselves from their competitors using business strategies taken from the
physical world. Consequently, online businesses are finding it increasingly
expensive to locate and attract the right types of Web site visitors and
increasingly difficult to convert these visitors into profitable and long-term
customers.
 
  Evolution of Online Business
 
  As the next generation of online business models evolve, companies are
changing the ways they measure their success online. Both advertising- and
commerce-based businesses have begun to use the percentage of Web site
visitors that actually transact business, or the conversion rate, as the key
gauge of their effectiveness in attracting and retaining loyal customers out
of their total Web site visitor population. According to Forrester Research,
the current average conversion rate for first-time visitors to an electronic
commerce Web site is 2.7%, a rate similar to unsolicited direct mailings. To
address this problem, businesses are beginning to focus their strategies on
increasing online conversion rates by more effectively engaging a new type of
"connected customer." Connected customers are individuals who place more value
on information convenience, online advisory services and improved access to
products and services, than on price and physical geographic location.
 
  To capture the connected customer, businesses must focus on developing and
executing a new set of online strategies to build long-term customer
relationships and strengthen customer loyalty. To attract connected customers,
businesses must provide users with more relevant and targeted experiences each
time they interact with the company online. To achieve this objective,
businesses must provide potential customers with greater information
convenience, online advisory services and improved access to products and
services.
 
  For the connected customer, information convenience means having all of the
data necessary to make a decision at one Web site. As a result, businesses are
finding it necessary to broaden their Web offerings beyond their own products
and services. Many online businesses are acquiring rich, third-party content
and product lines that allow them to deliver highly interactive, topical
portals that provide the convenience of one-stop shopping. For example, an
online stock brokerage firm might license daily industry news, company
 
                                      28
<PAGE>
 
analyses, and financial planning articles to provide their customers with a
complete set of financial management information on a single Web site.
 
  Increasingly, businesses must also offer online advisory services to provide
the expertise the customer needs to make an informed purchasing decision. For
example, an online travel agency might add advisory services that help
vacation travelers perform extensive pre-purchase research on their favorite
destinations. Through highly personalized services based on the collection and
analysis of customer profiles, businesses can enhance the lifetime value of
each customer, increase customer switching costs and create strong competitive
barriers.
 
  Businesses also are extending their online reach to engage potential
customers in more online locations than just their own Web sites. To increase
Web-based revenues, businesses need to maximize not only the number of
visitors and customers coming to their own Web sites, but also their total
online reach across their entire Customer Chain. For example, a business that
sells books online needs to reach not only the buyers that come to its own Web
site, but also visitors to other book-related sites, such as locations
dedicated to authors, book reviews and literature. In effect, it is as
necessary for businesses to create broad distribution and reseller
relationships online as it is in the physical world in order to have as many
points of contact with the customer as possible. The creation of such a super-
distribution model forms an instantaneous, worldwide distribution system. The
Internet has made it possible for all companies to have a worldwide online
distribution system, a system that was previously available only to large
companies that could afford to build out such a network in the physical world.
 
  Need for Comprehensive IRM Solutions
 
  As online business models evolve and the amount of business transacted on
the Web increases, enterprises are seeking new Internet solutions that will
enable them to develop, maintain and leverage relationships with customers and
affiliates. Much as companies adopted Enterprise Resource Planning software in
the late-1980s to manage back-office operations and Sales Force Automation
software in the mid-1990s to manage front-office operations, many businesses
are now searching for IRM software solutions to help them manage their online
customer relationships. Businesses realize that IRM solutions, like other
enterprise solutions, are mission-critical and pose significant technological
challenges that require large resource commitments. For example, early
adopters of IRM strategies, such as Amazon.com, built in-house solutions that
required significant custom development, evaluation, implementation and
integration of disparate technologies and platforms. Companies building these
solutions internally face long development cycles, high ongoing maintenance
costs, and limited functionality and scalability.
 
  Accelerated adoption of the Internet as a business channel is driving
businesses to seek enterprise software providers that have the expertise to
deliver solutions that minimize their time to market and maximize the value of
their Internet investment. To date, software providers have focused on
developing applications that managed discrete portions of IRM, such as
transaction management, catalog tools, collaborative
filtering/personalization, authoring, site management and application
development. Today, however, businesses are increasingly demanding an
integrated package of platforms, tools and applications that address all
aspects of IRM, rather than point products and toolkits. A fully integrated
IRM solution must include the ability to attract, engage and retain customers
and understand their needs and preferences via a direct relationship through a
company's Web site. This solution also must enable companies to create and
manage Customer Chains, value-added distribution networks whereby a company
can distribute its electronic goods and services outside of its own Web site
through a network of reseller, affiliate and partner Web sites. These
requirements demand an IRM solution that supports advanced content management
and syndication, personalization and decision support capabilities.
 
THE VIGNETTE SOLUTION
 
  Vignette is a leading global provider of IRM software products and services
specifically designed to enable businesses to enhance the value of their Web-
based relationships, maximize the return on their Internet-related investments
and capitalize on the substantial growth of the Internet as a new business
channel. The Company's
 
                                      29
<PAGE>
 
IRM solutions enable businesses to create and manage Internet business
channels that attract, engage and retain online customers. Vignette believes
its solutions allow its clients to increase their online effectiveness and
improve customer conversion rates, resulting in greater Web-based revenues and
market share. The Company's integrated solution set includes an enterprise-
class Internet application platform, as well as a set of tools for business
and technical managers to interact with customers through the Web site and
control its operation. Vignette Syndication Server, formally announced in
October 1998, will extend the Company's application platform to enable the
Company's clients to create and manage Customer Chains. Vignette is focused on
continuing to develop and extend its product and service offerings to provide
its clients with a comprehensive means for building, managing and delivering
sophisticated IRM solutions, thereby increasing its clients' return on their
Internet investments.
 
  The Company believes its comprehensive, integrated IRM solutions represent a
fundamentally new approach to doing business on the Internet and provide its
clients with the following benefits:
 
  Higher Customer Conversion and Retention Rates. The Company's products and
services enable its clients to use the Internet as a channel to build
profitable, long-term customer relationships and to use those relationships to
create new marketing opportunities to drive revenue growth. Businesses that
use the Company's solutions can develop Internet applications that interact,
as opposed to solely transact, with Web visitors. For instance, the Company's
IRM platform incorporates unique lifecycle personalization technology that
allows the Company's clients to create personalized Web experiences that
engage visitors and encourage return visits through tailored, customized
interactions. The Company believes that these personalized experiences enhance
customer loyalty, satisfaction and retention, resulting in higher conversion
rates. By creating Internet applications that are designed to appeal to new
customers and promote long-term, online customer relationships, businesses are
better positioned to capture increased online revenues.
 
  Increased Revenue Opportunities through More Flexible Business Model. The
Company's solutions are designed to enable its clients to pursue a broad range
of business opportunities that enhance Web-based revenues, such as co-
branding, multiple Web site production and super-distribution. The Company's
clients have obtained partner license fees in return for co-branding their Web
sites with partner logos, content and navigation. For example, a major portal
provider has co-branded its destination with over 100 Internet Service
Providers ("ISPs"), with each version of the Web site targeted specifically
for that ISP's customer base. In return, this portal receives significant
royalty payments from each ISP with very little actual cost to produce the
branded Web site. Vignette's multiple Web site production capabilities have
enabled a major online news provider to use a small team to create over 200
online community Web sites that are specific to urban areas in and around
their local community. Each community has its own Web site that contains local
advertising and content. The news provider was able to generate increased
advertising revenue from these localized Web sites.
 
  Rapid Time To Market. Businesses using Vignette solutions can develop IRM
applications more rapidly than most other third-party or in-house
alternatives. As a result, Vignette's solutions permit businesses to expand
their existing online business and enter into new online markets on an
accelerated time frame. Clients benefit from Vignette's component-based
application architecture that maximizes content and application reusability
and Web site performance. Many of the Company's clients take an integrated
approach to the construction and delivery of their relationship management
applications. Vignette's professional services organization provides these
clients with business strategy consulting, project management and application
development implementation. Vignette's integrated approach to delivering its
products and services permits its clients to deploy IRM solutions quickly and
cost effectively, thereby increasing online revenues and market share.
 
  Increased Operational Control of Internet Applications at a Lower Effective
Cost. The Company's IRM solutions permit clients to manage their Internet
business channels more efficiently and with greater control than most in-house
or other third-party alternatives. Vignette's product features also
dramatically reduce the amount of labor and capital expenditure required to
operate and maintain sites on the Internet. The Company's solutions
incorporate: (i) content management capabilities designed to increase the
efficiency of team-based Web site
 
                                      30
<PAGE>
 
production, enhance application developer productivity and reduce maintenance
costs; (ii) decision support capabilities that allow businesses to analyze
customer preferences, examine demographic segmentation and determine the
popularity of individual products and services; and (iii) a scalable
application server platform which is capable of handling a very large number
of Web site visitors with optimized performance while substantially curtailing
Web server hardware expenditures. Vignette's products and services provide
clients with greater operational control and compelling cost advantages in
operating and maintaining their Web sites, as well as in the cost of customer
acquisition and retention.
 
STRATEGY
 
  The Company's objective is to enhance its position as a leading global
provider of IRM solutions. To achieve this objective, the Company has adopted
the following strategies:
 
  Maintain Leadership in IRM Solutions Market. Vignette's industry-leading IRM
solutions enable enterprises to build and deploy effective online businesses.
Vignette's StoryServer 4 application platform allows businesses to maximize
their online potential by offering relevant products and services to the
appropriate customer audience, thereby increasing customer conversion rates

products and services across an extensive network of reseller, affiliate and
partner Web sites. In the future, the Company intends to maintain its
leadership position by developing new IRM products and services to help
businesses generate new online revenue opportunities.
 
  Expand Sales Channels to Drive Market Penetration. The Company is working to
increase customer adoption of its solutions by expanding its direct sales
operations and its indirect sales channels through additional relationships
and strategic alliances with key systems integrators, value-added resellers
("VARs") and original equipment manufacturers ("OEMs"). The Company believes
that a multi-channel sales effort will broaden customer awareness of the
Company's products and will allow it to effectively target a wide variety of
industries that would benefit from the Company's solutions.
 
  Expand International Presence. Vignette believes that there will be
significant international opportunities for its products and services and
continues to expand its global marketing and distribution efforts to address
the range of markets and applications for its IRM solutions. The Company plans
to continue aggressive expansion of its international presence by adding
direct sales personnel and increasing its indirect sales channels to fully
capitalize on international market opportunities. The Company has opened sales
offices in Hamburg, Germany and London, England and intends to continue its
expansion throughout Europe, Asia and those regions where businesses and other
institutional clients are using distributed networks and the Internet to
create sales opportunities.
 
  Leverage Professional Services Capabilities. Vignette has established
successful relationships with its clients by serving as an advisor in
developing and deploying IRM solutions. The Company is extending its direct
professional services capabilities to provide an expanded set of services to
address such areas as online business strategy, project management and
application development. In addition, the Company intends to offer similar
high-quality professional services capabilities through third-party alliances
and is currently focused on the development of relationships with VARs and
systems integrators. By offering its clients a full range of professional
services on a global basis, the Company believes it can broaden market
awareness about the advantages of its IRM solutions and create opportunities
to sell new or enhanced products to clients.

CASE STUDIES
 
  The following case studies illustrate the use of StoryServer by three of the
Company's clients.
 
  Online Travel Services Company
 
  A highly successful online travel services company selling an increasingly
commoditized product faced intense competition from two large online
competitors. The firm elected to focus its business on vacation travelers who
make highly considered purchases and need value-added travel planning
assistance before making purchasing decisions. To increase its revenue targets
and customer conversion rates, the firm needed an IRM system that delivered
interactive travel planning assistance to facilitate vacation purchases
through its Web site. Such a system would have to handle a multi-million
member customer base and support tens of thousands of personalized visitor
sessions each day. In addition, to meet the firm's application goals, the
system also would have to automatically integrate a series of travel-related
resources licensed and syndicated from other Web sites, and integrate this
content within the firm's travel planning application. An internally-built
system would have been too expensive, and most packaged solutions did not
provide an application architecture that would accommodate the necessary
content flexibility or deliver adequate system performance.
 
  The travel services firm deployed StoryServer and worked with Vignette
Professional Services to launch a major new version of their Web site in less
than six months. The firm was first to market with a Web-based vacation travel
planning service that integrated syndicated travel guide content and delivered
it as an integral part of their IRM application. The firm was immediately able
to process significantly more visitor sessions because Web server utilization
dropped from 90% to 10%. By reducing Web server utilization, the firm was able
to delay significant planned hardware expenditures. StoryServer also enabled
the firm to reduce its time to deployment for new versions of the travel
planning application, creating significant advantages over its online
competitors. The firm's marketing staff is now considering additional
syndication arrangements to further increase the customer value of the travel
planning application. StoryServer provided the company with an IRM solution
that significantly increased its customer conversion rates.
 
  Financial Services Company
 
  A major retail banking company planned an extensive Internet banking
initiative in which the Internet would become a primary business channel for
its retail customers. The bank's existing Web site was a simple system that
allowed customers to check account balances and read information about its
banking products. The bank needed to position the new version of its Web site
as a daily financial gateway that would assist customers with loan selection,
college planning, house purchases and managing personal stock portfolios. The
problem was that the bank's existing Web systems were designed as either a
means of delivering simple brochure content, or as Web-enabled front ends on
top of its proprietary transaction systems. Neither of these systems by
themselves could create an integrated advisory experience that would
reasonably engage clients on a daily basis and allow the bank to better retain
customers. The bank's new Web-based business required an Internet application
platform that could deliver a set of highly interactive, content-rich
applications to a large, diverse population of customers, and be managed on a
real-time basis by the bank's marketing managers. The bank knew that its
competitors were working on a similar project, and that time to market was
critical in order to increase market share and establish itself as an Internet
banking leader.
 
  The bank selected Vignette's StoryServer product as the strategic technology
platform for the future of its relationship-based banking business on the Web.
By engaging VPS, the bank was able to meet its application functional
requirements and launch dates, going online within months of its investment in
the Vignette solution. The bank's new Web site delivers a broad personal
banking experience, offering planning tools for products and services ranging
from money management to auto loans to insurance, as well as an individual
investor portfolio management system. In addition, the Web site delivers a
news and research section that syndicates daily investor information from the
Dow Jones news service. The success of this venture recently resulted in the
bank's new parent deciding to invest in another deployment of StoryServer for
its next generation retail banking Web site due to be launched early next
year.

  Worldwide Provider of News and Information
 
  A major news and information publishing company planned on entering the
online regional communities business to compete with CitySearch and
Microsoft's Sidewalk. The company's business plan called for a major regional
Web site accompanied by up to 250 local community Web sites targeted to reach
the local online communities. Existing technologies made delivering multiple
online communities cost-prohibitive because the cost of producing and managing
each new Web site outweighed the revenue potential. The company needed a
platform that would enable it to rapidly and cost-effectively deliver new
online services across dozens of regional Web sites, target local businesses
as advertisers and let local community leaders as well as staff editors
produce editorial content while controlling the overall production of each
property at a central location. Likewise, the development team needed a highly
scalable application architecture that would allow new online properties to be
designed and deployed using reusable applications and content yet allow each
online community Web site to uniquely interact with its visitors on topics of
local interest.
 
  The client chose Vignette because StoryServer offered a complete end-to-end
solution for hosting multiple Web sites from a single platform and content
base, and automating content management so that the control over the
production of each property was centralized. Using StoryServer, the company
was able to build a broad base of advertising slots and maximize the revenue
potential of each Web site without the expense of running each property
individually. The production team now produces enhanced application
functionality from a central location for the various Web sites. At the same
time, community leaders retain control over their own presentation, navigation
and content. As a result, the company has been able to increase its market
share position for interactive community Web sites in its region. It has
rapidly deployed dozens of local properties, and established a fixed cost
business model that limits the growth in developer, producer and editor
headcount required to support the opportunity.
 
TECHNOLOGY
 
  The Company believes its advanced technology enables its clients, partners
and consultants to build, deliver and manage enterprise-class IRM systems into
the market in less time, at lower cost and with better business results than
existing alternatives.
 
  Product Architecture
 
  The Company believes that it has developed a unique architecture for meeting
the technical demands of applications designed for Internet Relationship
Management. By emphasizing an application architecture based on content
management; a lifecycle personalization model that effectively accommodates
both Web customer acquisition and retention; and a patented design for
extremely scalable and high-performance Web page delivery, the Vignette
solution provides an efficient architecture for clients to build and deploy
highly scalable IRM applications quickly and cost-effectively. The Company
believes that this architecture also provides a strong foundation on which the
Company can develop future products.
 
  Content Management. The Company has developed proprietary content management
technology designed to manage the high volume of dynamic interactions that
occur between many concurrent Web site visitors and the relationship
management application. The content management system provides three key
functions:
 
  . Content Abstraction Services. Allow application developers to build and
    deploy applications that can access and manage any type of content (such
    as relational data, flat files, or XML (Extensible Markup Language) data)
    through a single API (Application Programming Interface) model. This
    simplifies application development and significantly reduces time-to-
    deployment by uncoupling decisions about storage repositories and data
    formats from application logic and protects existing database repository
    investments. The Company plans to further enhance the system's rapid
    application development capabilities in early 1999 with its Development
    Center tool, a visual data modeling and drag-and-drop application builder
    tool that will take further advantage of these content abstraction
    services.
 
                                      37
<PAGE>
 
  . Automated Asset Management. Provides a broad set of functionality for
    managing and automating most tasks associated with managing content
    assets, including production team access control, asset-specific
    workflow, version control, launch and expiration scheduling, and visual
    project management.
 
  . Content Components. Greatly enhance the template-based approach to
    Internet application development. Components allow Internet applications
    to be built and operated in an object-oriented fashion, with components
    serving as the building blocks for dynamic assembly and adaptive
    navigation. Unlike other products that require complex programming to
    support interactivity, StoryServer 4 provides native support for
    interactive content components. This approach eliminates the problem of
    inflexible application structures associated with existing template-based
    dynamic architectures.
 
  Lifecycle Personalization. The Company's lifecycle personalization services
are designed to help clients substantially increase their conversion rates and
increase the lifetime value of the typical online customer by managing
relationships through their complete lifecycle. These services (described
below) enable clients to personalize Web experiences by adapting the site's
presentation, navigation and content based on implicitly observed behavior and
explicitly stated preferences as the relationship evolves over a number of
interactions from anonymous visitor to well-known customer. The Company
believes that its approach requires less time and effort to deploy and
maintain, and requires substantially less investment in Web server hardware
than competing alternatives.
 
  The Company's lifecycle personalization tools consist of five primary
components, which when utilized in combination with content management
functions, enable clients and partners to develop applications that are
effective for both online customer acquisition and customer retention.
 
  . Presentation Agent for System Targeting. Automatically adapts the
    application's presentation to accommodate a new, anonymous visitor's
    environment to present content that is suited to the visitor's browser
    capabilities, operating system, and local language.
 
  . Matching Agent for Behavior Targeting. As a new visitor becomes familiar
    with the site, the Matching Agent uses observations about a visitor's
    behavior on the Web site to infer the visitor's interest and to adapt
    navigation and content to observed affinities. With the Matching Agent,
    businesses can implement merchandising over the Web without requiring
    visitors to explicitly divulge information about themselves.
 
  . Recommendation Agent for Needs Targeting. The Recommendation Agent is
    utilized when visitors become sufficiently familiar with the site to
    facilitate targeted suggestions. The Recommendation Agent recommends
    content to a visitor that others with similar tastes found interesting.
 
  . Personal Pages for Customization. Useful at the well-known stage, the
    site can offer the capability for visitors to define personal pages that
    are explicitly tailored to their needs each time they return to the site.
 
  . Open Profiling Services. Open Profiling Services manage and populate a
    centralized repository of visitor profile and content information. This
    feature provides a visitor registry for storing visitor information, a
    content catalog for creating taxonomy of content on the Web site for use
    in personalization, and an Observation Manager that observes, tracks and
    records visitor behavior and preferences without impacting site
    performance.
 
  Syndication Services. The forthcoming Vignette Syndication Server will
utilize a proprietary set of technologies that allows customers to build
online reseller channels through affiliate Web sites. VSS allows the creation
of these channels by using a logical set of content ("packages"), business
rules for governing affiliate relationships ("subscriptions") and automated
remote management services for managing its content within its affiliate Web
sites. These proprietary services have been based on the emerging Information
and Content Exchange ("ICE") specification standard for content syndication,
which is an XML-based specification being
 
                                      38
<PAGE>
 
jointly developed by the Company and over seventy other companies including
Microsoft, Sun Microsystems and Adobe. The Company believes that by fostering
the creation and adoption of an open standard for content syndication, and
being the first company to provide proprietary value-added services in the
delivery of a product that embodies these concepts, it will be able to quickly
establish technology leadership in this arena.
 
  Scalability and Performance
 
  The Company believes that one of its key technological strengths is
StoryServer 4's ability to deliver industry-leading Web page delivery
performance and scalability while running on low cost Web server hardware.
Internet applications that are built with competing products that dynamically
generate Web pages can be significantly slower (depending on the server
configuration) than first generation static Web sites. This degrades the
overall Web site experience for the site visitor, lowers the visitor's
interest in returning to the Web site, reduces the client's ability to handle
large visitor traffic volumes, and creates a requirement for the client to
significantly increase Web server capital equipment expenditures.
 
  StoryServer 4's ability to deliver unique performance characteristics is
achieved using three techniques:
 
  . A patented caching mechanism is integrated with the product's content
    component architecture and allows applications to deliver dynamically
    generated and personalized Web pages at speeds nearly equivalent to the
    performance of static Web page delivery.
 
  . Integration of this patented caching mechanism with the Company's
    personalization technologies, so highly personalized Web pages can be
    delivered without the cost and real-time delay of significant
    transactional computation required by other solutions attempting to offer
    personalization capabilities.
 
  . The ability to distribute application server components of the platform
    product across multiple physical Web servers allows high-end sites to
    scale up performance and gain increased system availability as a result.
 
  Adherence to Industry Standards
 
  The Company has invested significant resources in developing its
architecture to comply with widely accepted commercial software industry
standards for building large scale Internet applications. The Company's
products use SQL (Structured Query Language) for accessing RDBMSs (Relational
Database Management Systems), HTTP (Hypertext Transfer Protocol) for Internet
access, NSAPI (Netscape Application Programming Interface) for access to
Netscape's Internet servers, ISAPI (Information Server Application Programming
Interface) for access to Microsoft's Internet servers, and XML for
representing and processing content. Adherence to these industry standards
provides compatibility with existing applications, enables ease of
modification and reduces the need for software to be rewritten, thus
protecting the client's investment. Furthermore, the Company's products can be
operated in conjunction with RDBMSs provided by Oracle, Microsoft, Informix or
Sybase, utilizing their native, high-performance interfaces.
 
  The Company has focused its investments in particular on developing its
architecture to comply with XML, a recently approved standard for data
representation being adopted by the industry. Software systems that are XML-
compliant provide customers with the ability to reduce application development
time, easily integrate with legacy enterprise systems, and build applications
that span the business processes of the company, its suppliers, distributors
and customers. The Company believes that its rapid adoption of XML and its
leadership position in building applications based on XML will allow it to
further its technology leadership as this standard becomes the de facto data
representation model for enterprise applications delivery. Specifically, the
Company first introduced XML services in the 3.2 release of StoryServer and is
building its forthcoming Vignette Syndication Server on top of an XML-based
protocol known as ICE. The Company continues to invest in XML technologies and
participate as a member of the World Wide Web Consortium ("W3C") standards
committee, with representation on the W3C Advisory Committee.
 
  The Company develops most of its software in Java or C++, two widely
accepted standard programming languages for developing object-oriented
applications. The Company chooses whichever language is best suited
 
                                      39
<PAGE>
 
to the requirements of a particular component. The Company generally uses Java
to develop client programs, where the Company can benefit from the rapid
development capabilities and heterogeneous platform support capabilities of
Java. The Company actively supports its Java products on Sun Solaris, Windows
95, Windows NT, and Macintosh platforms, and continuously evaluates new
platforms as justified by the business. The Company generally uses C++ for
server programs, because of the Company's high scalability and performance
requirements.
 
RESEARCH AND DEVELOPMENT
 
  The Company has made substantial investments in research and development
through both internal development and technology acquisition. Although the
Company plans to continue to evaluate externally developed technologies for
integration into its product lines, the Company expects that most enhancements
to existing and new products will be developed internally.
 
  The majority of the Company's research and development activity has been
directed towards feature extensions to its family of products. This
development consists primarily of adding new competitive product features and
additional tools and products as the Company expands into new markets.
 
  The Company's research and development expenditures, including the write-off
of acquired in-process research and development, for fiscal 1996, 1997 and for
the nine months ended September 30, 1998 were approximately $2.8 million, $2.9
million and $6.9 million, respectively. The Company expects that it will
continue to commit significant resources to research and development in the
future. All research and development expenses have been expensed as incurred.
See "Management's Discussion and Analysis of Financial Condition and Results
of Operations."
 
  The market for the Company's products and services is characterized by rapid
technological change, frequent new product introductions and enhancements,
evolving industry standards, and rapidly changing customer requirements. The
introduction of products incorporating new technologies and the emergence of
new industry standards could render existing products obsolete and
unmarketable. The Company's future success will depend in part on its ability
to anticipate changes, enhance its current products, develop and introduce new
products that keep pace with technological advancements and address the
increasingly sophisticated needs of its customers. See "Risk Factors--Risks of
Rapid Technological Change."
 
SALES AND MARKETING
 
  The Company markets its products primarily through its direct sales force
and also intends to expand its indirect sales through additional relationships
with systems integrators, VARs and OEMs. The Company generates leads from a
variety of sources, including businesses seeking partners to develop
interactive marketing and selling applications. Initial sales activities
typically include a demonstration of the Company's product capabilities
followed by one or more detailed technical reviews. As of September 30, 1998,
the direct sales force consisted of 48 sales executives and support personnel.
 
  The Company seeks to establish partnerships with major industry vendors that
will add value to the Company's products and expand distribution
opportunities. The Company also pursues marketing agreements with premier
content authoring vendors, site usage analysis vendors and vertically aligned
Web server vendors.
 
  The Company uses a variety of marketing programs to build market awareness
of the Company, its brand name and its products, as well as to attract
potential customers for its products. A broad mix of programs are used to
accomplish these goals, including market research, product and strategy
updates with industry analysts, public relations activities, direct mail and
relationship marketing programs, seminars, trade shows, speaking engagements
and Web site marketing. The Company's marketing organization also produces
marketing materials in support of sales to prospective customers that include
brochures, data sheets, white papers, presentations and demonstrations.
 
STRATEGIC ALLIANCES
 
  A critical element of the Company's sales strategy is to establish strategic
alliances to assist the Company in marketing, selling and developing customer
applications, as well as to increase product interoperability within the
 
                                      40
<PAGE>
 
industry. This approach is intended to increase the number of personnel
available to perform application design and development services for the
Company's customers; and provide additional marketing expertise and technical
expertise in certain vertical industry segments. These alliances fall into
four categories: (i) the Information & Content Exchange alliance, (ii)
platform alliances, (iii) technology alliances and (iv) design alliances.
 
  Information and Content Exchange Alliance
 
  To facilitate the adoption of Web-based content syndication technologies in
the marketplace, the Company co-founded the ICE working group to create an
industry-standard protocol for enabling cross-Website syndication
capabilities. In January 1998, the Company formed the ICE Authoring Group
comprising 12 additional companies: Adobe, CNET, Firefly, Hollinger
International, Microsoft, National Semiconductor, Net Perceptions, News
Internet Services, Preview Travel, Sun Microsystems (JavaSoft), Tribune Media
Services and Ziff Davis. In support of this protocol creation, the Company has
also co-founded the ICE Advisory Council comprising over 70 companies that
provide input and feedback to the Authoring Group during the creation of the
protocol.
 
  Platform Alliances
 
  To ensure that the Company's products are based on industry standards and
take advantage of current and emerging technologies, the Company emphasizes
strategic platform alliances. The benefits of this approach include enabling
the Company to focus on its core competencies, reducing time to market and
simplifying the task of designing and developing applications by both the
Company and its customers. Key strategic platform alliances to date have
included strategic relationships with Sun Microsystems, developer of the Java
language; Oracle and Sybase, providers of industry-standard relational
databases; and Hewlett-Packard, a leading Internet server hardware
manufacturer.
 
  Technology Alliances
 
  To assure that the Company's products are compatible with the latest
technology, the Company has formed technology alliances with many of the
leading technology companies serving the Web. The Company and its partners
exchange marketing and sales information, sales leads, and technology
integration practices. The Company's technology alliance categories include:
e-commerce transactions; ad management; site traffic and management; multi-
lingual site support and translations; personalization; operations management;
security; information architecture and navigation; high value content loading
and maintenance and building online communities.
 
  Design Alliances
 
  Prospective customers of the Company often retain the services of Web design
firms. These companies' primary business is to provide design services rather
than software resale. However, many are regarded as thought leaders in the
field and have influence over technology choices for the customer. The Company
has established relationships with 36 of these design firms.
 
  The Company's strategy is to establish additional design alliances as new
technologies and standards emerge, although no assurance can be given that the
Company will be successful in establishing such alliances.
 
COMPETITION
 
  The market for IRM products is intensely competitive, subject to rapid
technological change and significantly affected by new product introduction
and other market activities of industry participants. The Company expects
competition to persist and intensify in the future. The Company has three
primary sources of competition: in-house development efforts by potential
clients or partners; other vendors of software that directly address IRM, such
as BroadVision; and developers of point solution software that address only
certain technology components of IRM (e.g., content management), such as Inso
Corporation.
 
 
                                      41
<PAGE>
 
  Many of the Company's competitors have longer operating histories and
significantly greater financial, technical, marketing and other resources than
the Company and thus may be able to respond more quickly to new or changing
opportunities, technologies and customer requirements. Also, many current and
potential competitors have wider name recognition and more extensive customer
bases that could be leveraged, thereby gaining market share to the Company's
detriment. Such competitors may be able to undertake more extensive
promotional activities, adopt more aggressive pricing policies, and offer more
attractive terms to purchasers than the Company. In addition, current and
potential competitors have established or may establish cooperative
relationships among themselves or with third parties to enhance their
products. Accordingly, it is possible that new competitors or alliances among
competitors may emerge and rapidly acquire significant market share.
 
  Such competition could materially and adversely affect the Company's ability
to obtain revenues from license fees from new or existing customers and
professional service fee revenues from existing customers on terms favorable
to the Company. Further, competitive pressures may require the Company to
reduce the price of its software. In either case, the Company's business,
operating results and financial condition would be materially and adversely
affected. There can be no assurance that the Company will be able to compete
successfully with existing or new competitors or that competition will not
have a material adverse effect on the Company's business, financial condition
and operating results. See "Risk Factors--Our Market is Highly Competitive."
 
PROPRIETARY RIGHTS AND LICENSING
 
  The Company's success and ability to compete is dependent on its ability to
develop and maintain the proprietary aspects of its technology and operate
without infringing on the proprietary rights of others. The Company relies on
a combination of patent, trademark, trade secret, and copyright law and
contractual restrictions to protect the proprietary aspects of its technology.
These legal protections afford only limited protection for its technology. The
Company presently owns one patent and has a single patent application and nine
trademark applications pending in the United States. The Company seeks to
protect its source code for its software, documentation and other written
materials under trade secret and copyright laws. The Company licenses its
software pursuant to signed license or "shrinkwrap" agreements, which impose
certain restrictions on the licensee's ability to utilize the software.
Finally, the Company seeks to avoid disclosure of its intellectual property by
requiring employees and consultants with access to the Company's proprietary
information to execute confidentiality agreements with the Company and by
restricting access to the Company source code. Due to rapid technological
change, the Company believes that factors such as the technological and
creative skills of its personnel, new product developments and enhancements to
existing products are more important than the various legal protections of its
technology to establishing and maintaining a technology leadership position.
 
  Despite the Company's efforts to protect its proprietary rights,
unauthorized parties may attempt to copy aspects of the Company's products or
to obtain and use information that the Company regards as proprietary.
Policing unauthorized use of the Company's products is difficult and while the
Company is unable to determine the extent to which piracy of its software
exists, software piracy can be expected to be a persistent problem. Litigation
may be necessary in the future to enforce the Company's intellectual property
rights, to protect the Company's trade secrets, to determine the validity and
scope of the proprietary rights of others or to defend against claims of
infringement or invalidity. However, the laws of many countries do not protect
the Company's proprietary rights to as great an extent as do the laws of the
United States. Any such resulting 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. There can be no
assurance that the Company's means of protecting its proprietary rights will
be adequate or that the Company's competitors will not independently develop
similar technology. Any failure by the Company to meaningfully protect its
property could have a material adverse effect on the Company's business,
operating results and financial condition.
 
  To date, the Company has not been notified that its products 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 the
Company's current or future products. The Company expects that developers of
Web-based commerce software
 
                                      42
<PAGE>
 
products will increasingly be subject to infringement claims as the number of
products and competitors in the Company's industry segment grows and as the
functionality of products in different segments of the software industry
increasingly overlaps. Any such claims, with or without merit, could be time-
consuming to defend, result in costly litigation, divert management's
attention and resources, 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. A successful claim of product infringement against the
Company and the failure or inability of the Company to license the infringed
technology or develop or license technology with comparable functionality
could have a material adverse effect on the Company's business, financial
condition and operating results. See "Risk Factors--Limited Protection of
Proprietary Technology; Risks of Infringement."
 
  The Company integrates third-party software into its products. This third-
party software may not continue to be available on commercially reasonable
terms. For instance, the Company licenses GroupLens Express from Net
Perceptions for certain personalization functionality in StoryServer. The
agreement expires in October 1999, but it is renewed automatically unless
either party gives 60 days notice prior to the renewal date. If the Company
cannot maintain licenses to key third-party software, such as GroupLens
Express, shipments of its products could be delayed until equivalent software
could be developed or licensed and integrated into its products, which could
materially adversely affect its business, operating results and financial
condition.
 
EMPLOYEES
 
  As of September 30, 1998, the Company had a total of 219 employees. Of the
total employees, 69 were in engineering, 72 in sales and marketing, 48 in
professional services and 30 in finance and administration. The Company's
future success will depend in part on its ability to attract, retain and
motivate highly qualified technical and management personnel, for whom
competition is intense. From time to time the Company also employs independent
contractors to support its professional services, product development, sales,
marketing and business development organizations. The Company's employees are
not represented by any collective bargaining unit, and the Company has never
experienced a work stoppage. The Company believes its relations with its
employees are good.
 
PROPERTIES
 
  The Company's headquarters are currently located in a leased facility in
Austin, Texas, consisting of approximately 25,000 square feet of office space,
substantially all of which is under a three-year lease expiring December 31,
2000. The Company has an additional facility in Austin, Texas, of
approximately 12,000 square feet which is under a six-month sub-lease expiring
in December 1998. The Company is relocating and consolidating its operations
in December 1998 to a new facility in Austin, Texas. The new facility consists
of approximately 79,000 square feet under a five-year lease with expansion
options. The Company also has leased offices for sales and support personnel
in Atlanta, Georgia; Boston, Massachusetts; Chicago, Illinois; Dallas, Texas;
Newport Beach, California; New York, New York; San Mateo, California;
Valencia, California; and Sydney, Australia.
 
LEGAL PROCEEDINGS
 
  The Company is not a party to any material legal proceedings.

(1) Each of the options listed in the table is immediately exercisable. The
    shares purchasable thereunder are subject to repurchase by the Company at
    the original exercise price paid per share upon the optionee's cessation
    of service prior to vesting in such shares. The repurchase right lapses
    and the optionee vests as to 25% of the option shares upon completion of
    one year of service from the date of grant and the balance in a series of
    equal quarterly installments over the next three years of service
    thereafter. The option shares will vest upon an acquisition of the Company
    by merger or asset sale, unless the Company's repurchase right with
    respect to the unvested option shares is transferred to the acquiring
    entity. The option shares will also vest should the optionee's employment
    or service be involuntarily terminated within 18 months following an
    acquisition of the Company by merger or asset sale. Each of the options
    has an eight year term, subject to earlier termination in the event of the
    optionee's cessation of service with the Company.
 
(2) Based on an aggregate of 1,268,352 options granted to employees of the
    Company under the 1995 Stock Option/Stock Issuance Plan during the 12
    months ended December 31, 1997.
 
(3) The exercise price was equal to the fair market value of the Company's
    Common Stock as valued by the Board of Directors on the date of grant. The
    exercise price may be paid in cash, in shares of the Company's Common
    Stock valued at fair market value on the exercise date or through a
    cashless exercise procedure involving a same-day sale of the purchased
    shares. The Company may also finance the option exercise by lending the
    optionee sufficient funds to pay the exercise price for the purchased
    shares, together with any federal and state income tax liability incurred
    by the optionee in connection with such exercise.
 
(4) The potential realizable value is calculated based on the term of the
    option at the time of grant (eight years). Stock price appreciation of 5%
    and 10% is assumed pursuant to rules promulgated by the Securities and
    Exchange Commission and does not represent the Company's prediction of its
    stock price performance. The potential realizable values at 5% and 10%
    appreciation are calculated by assuming that the exercise price on the
    date of grant appreciates at the indicated rate for the entire term of the
    option and that the option is exercised at the exercise price and sold on
    the last day of its term at the appreciated price.
 
  In addition to the options listed in the table, stock options were granted
in 1998 to certain of the Named Executive Officers and to other executive
officers under the Company's 1995 Stock Option/Stock Issuance Plan for the
following number of shares and at the exercise prices indicated: Mr. Peters,
593,845 shares at $2.09 per share; Ms. Atherton, 34,180 shares at $0.42 per
share; Mr. Garber, 103,600 shares at $0.42 per share; Mr. Klante, 105,105
shares at $0.42 per share; Mr. Lynch, 42,324 shares at $0.42 per share; Mr.
Vollman, 105,105 shares at $0.42 per share, 35,035 shares at $0.42 per share,
and 30,401 shares at $7.00 per share; and Mr. Webber, 25,000 shares at $0.42
per share. Each of the options is immediately exercisable. The shares
purchasable thereunder are subject to repurchase by the Company at the
original exercise price paid per share upon the optionee's cessation of
service prior to vesting in such shares. The repurchase right lapses as to 25%
of the shares upon completion

of the 1998 Equity Incentive Plan, has the authority to provide for
accelerated vesting of the shares of Common Stock subject to outstanding
options held by the Named Executive Officers and any other executive officer
or director in connection with certain changes in control of the Company or
the subsequent termination of the officer's employment following the change in
control event. Except for Greg Peters, none of the Named Executive Officers
have employment agreements with the Company, and their employment may be
terminated at any time. The Company has entered into an agreement with Mr.
Peters, the Company's President and Chief Executive Officer, dated April 30,
1998, which provides for a severance payment in the amount of six months of
base salary in the event that Mr. Peters' employment is involuntarily
terminated without cause and a severance payment equal to one year of base
salary plus target bonus in the event that Mr. Peters' employment is
involuntarily terminated without cause following certain changes in control of
the Company. The letter agreement also provides for acceleration of vesting of
option shares as if Mr. Peters remained employed for two additional years in
the event that his employment is involuntarily terminated following certain
changes in control of the Company. However, if a change in control occurs
after the offering at a price per share higher than the price for the
offering, then Mr. Peters will fully vest in his option shares.
 
EXECUTIVE BONUS PLAN
 
  The Company has adopted a bonus program pursuant to which selected officers
and other full-time employees are eligible for annual cash bonuses based upon
a combination of the Company achieving specified objects and the employee
meeting specified individual performance objectives.
 
EMPLOYEE BENEFIT PLANS
 
  1998 Equity Incentive Plan
 
  The Company's 1998 Equity Incentive Plan (the "Equity Plan") was adopted by
the Board on September 9, 1998, subject to stockholder approval. The number of
shares of Common Stock reserved for issuance under
 
                                      49
<PAGE>
 
the Equity Plan is equal to 1,000,000 shares plus the aggregate number of
shares remaining available for grant under the Company's 1995 Stock
Option/Stock Issuance Plan (the "Predecessor Plan"), plus an additional number
of shares equal to the number of shares reserved for issuance against options
outstanding under the Predecessor Plan as of the date of the Offering. As of
January 1 of each year, commencing with the year 1999, the number of shares
reserved for issuance under the Equity Plan will be increased automatically by
the lesser of (i) 5% of the total number of shares of Common Stock then
outstanding or (ii) 1,000,000 shares. As of September 30, 1998, no options had
been granted under the Equity Plan. Under the Equity Plan, employees, non-
employee members of the Board ("Outside Directors") and consultants may be
awarded options to purchase shares of Common Stock, stock appreciation rights
("SARs"), restricted shares or stock units (collectively, the "Awards").
Options may be incentive stock options designed to satisfy Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code") or nonstatutory stock
options not designed to meet such requirements. If restricted shares or shares
issued upon the exercise of options granted under this Plan or the Predecessor
Plan are forfeited, then such shares will again become available for awards
under the Equity Plan. If stock units, options or SARs granted under the
Equity Plan or the Predecessor Plan are forfeited or terminate for any other
reason before being exercised, then the corresponding shares will again become
available for awards under the Equity Plan.
 
  The Equity Plan is administered by the Company's Compensation Committee (the
"Committee"). The Committee has the complete discretion to determine which
eligible individuals are to receive any award, determine the type, number,
vesting requirements and other features and conditions of such award,
interpret the Equity Plan and make all other decisions relating to the
operation of the Equity Plan.
 
  The exercise price for non-qualified and incentive stock options granted
under the Equity Plan may not be less than 85% or 100%, respectively, of the
fair market value of the Common Stock on the option grant date and may be paid
in cash or in outstanding shares of Common Stock. Options may also be
exercised by using a cashless exercise method, a pledge of shares to a broker
or promissory note. The payment for the award of newly issued restricted
shares will be made in cash, by promissory note or the rendering of past or
future services.
 
  The Committee has the authority to modify, extend or assume outstanding
options and SARs or may accept the cancellation of outstanding options or SARs
in return for the grant of new options or SARs for the same or a different
number of shares and at the same or a different exercise price.
 
  Upon a Change in Control, an Award will become fully exercisable as to all
shares subject to such Award if such Award is not assumed by the surviving
corporation or its parent and the surviving corporation or its parent does not
substitute such Award with another award of substantially the same terms. In
the event of an involuntary termination of service within 18 months following
a Change in Control, the vesting of an Award will accelerate in full.
 
  A Change in Control includes (i) a merger or consolidation of the Company
after which the Company's then current stockholders own less than 50% of the
surviving corporation, (ii) sale of all or substantially all of the assets of
the Company, (iii) a proxy contest that results in replacement of more than
one-third of the directors over a 24-month period or (iv) acquisition of 50%
or more of the Company's outstanding stock by a person other than a trustee of
any of the Company's employee benefit plans or a corporation owned by the
stockholders of the Company in substantially the same proportions as their
stock ownership in the Company. In the event of a merger or other
reorganization, outstanding options, SARs, restricted shares and stock units
will be subject to the agreement of merger or reorganization, which may
provide for the assumption of outstanding Awards by the surviving corporation
or its parent, for their continuation by the Company (if the Company is a
surviving corporation), for accelerated vesting and accelerated expiration,
for settlement in cash followed by cancellation of the outstanding Awards.
 
  The Board may amend or terminate the Equity Plan at any time. Amendments may
be subject to stockholder approval to the extent required by applicable laws.
The Equity Plan will continue in effect unless otherwise terminated by the
Board.

  Employee Stock Purchase Plan
 
  The Board adopted the Company's Employee Stock Purchase Plan (the "Purchase
Plan") on September 9, 1998, subject to stockholder approval. A total of
750,000 shares of Common Stock have been reserved for issuance under the
Purchase Plan. As of January 1 each year, the number of shares reserved for
issuance under the Purchase Plan will be increased automatically by the lesser
of (i) 2% of the total number of shares of Common Stock outstanding or (ii)
750,000 shares. The Purchase Plan is intended to qualify under Section 423 of
the Code. Each calendar year, two overlapping offering periods each with a
duration of 24 months will commence on May 1 and November 1 (except that the
first offering period will commence on the effective date of the offering and
end on April 30, 2000). Each offering period contains four six-month
accumulation periods, with purchases occurring at the end of each six-month
accumulation period. However, the initial accumulation period will begin on
the effective date of the offering and end on April 30, 1999. The Purchase
Plan will be administered by the Committee. Each employee will be eligible to
participate after 90 days of employment if he or she is employed by the
Company for at least 20 hours per week and for more than five months per year.
The Purchase Plan permits each eligible employee to purchase Common Stock
through payroll deductions, which may not exceed 15% of an employee's cash
compensation. No more than 2,000 shares may be purchased on any purchase date.
The price of each share of Common Stock purchased under the Purchase Plan will
be 85% of the lower of (i) the fair market value per share of Common Stock on
the date immediately prior to the first date of the applicable offering period
(except that in the case of the first offering period, the price per share
will be the price offered to the public in the offering) or (ii) the fair
market value per share of Common Stock on the date at the end of the
applicable accumulation period. Employees may end their participation in the
Purchase Plan at any time during the accumulation period, and participation
ends automatically upon termination of employment with the Company.
 
  In the event of a Change in Control, all offering periods and accumulation
periods will terminate and each outstanding purchase right will be exercised.
The Board may amend or terminate the Purchase Plan at any time. However, the
Board may not, without stockholder approval, increase the number of shares of
Common Stock reserved for issuance under the Purchase Plan.
 
  1998 Non-Employee Directors Option Plan
 
  The Company's 1998 Non-Employee Directors Option Plan (the "Directors Option
Plan") was adopted by the Board of Directors on September 9, 1998, subject to
approval by the stockholders. Under the Directors Option Plan, non-employee
members of the Board of Directors will be eligible for automatic option
grants.
 
  A maximum of 250,000 shares of Common Stock has been authorized for issuance
under the Directors Option Plan. No shares have been issued under the
Directors Option Plan.
 
  The Directors Option Plan is self-administering but any administrative
determinations will be made by the Compensation Committee of the Board.
 
  The exercise price for options granted under the Directors Option Plan may
be paid in cash or in outstanding shares of Common Stock. Options may also be
exercised on a cashless basis through the same-day sale of the purchased
shares.
 
  Each individual who first joins the Board as a non-employee director on or
after the effective date of the Directors Option Plan and after the date of
this offering, whether through election or appointment, will receive at that
time an automatic option grant for 25,000 shares of Common Stock. In addition,
at each annual stockholders meeting, beginning in 1999, each non-employee
director will automatically be granted at that meeting, whether or not he or
she is standing for re-election at that particular meeting, a stock option to
purchase 2,500 shares of Common Stock. Automatic option grants will become
exercisable for 25% of the shares after one year of Board service and in a
series of equal quarterly installments over the next three years of service
thereafter. Each option will have an exercise price equal to the fair market
value of the Common Stock on the automatic grant date and a maximum term of
ten years, subject to earlier termination following the optionee's cessation
of Board service. However, vesting will automatically accelerate in full upon
a Change in Control.
 
  The Board may amend or modify the Directors Option Plan at any time. The
Directors Option Plan will terminate on September 8, 2008, unless sooner
terminated by the Board.

  Pursuant to the Stockholders' Agreement, dated as of February 5, 1996, John

Messrs. Thornton and Davoli each were granted an option to purchase 25,000
shares of the Company's Common Stock at an exercise price of $12.50 per share
subject to a four year vesting schedule in connection with their service as
members of the Board. See "Principal and Selling Stockholders" for more
information regarding securities held by these purchasers.
 
  In August 1998, CNET and the Company amended the Prism Agreement to provide
that CNET's and NBC Multimedia's jointly owned subsidiary, Snap! LLC, may use
an undefined number of copies of StoryServer for (i) Snap!'s Internet sites
accessible through www.snap.com and (ii) for certain Snap! LLC co-branded
sites. Such amendment also provides that if CNET no longer holds a 50% or more
ownership interest in Snap! LLC, any subsequent copies installed and used
after that time must be purchased from the Company. In consideration, CNET
assigned to the Company all rights and title to and interest in U.S. Patent
No. 5,740,430, issued on April 14, 1998, "Method and apparatus for server-
independent caching of dynamically-generated customized pages," and provided
$100,000 of advertising on CNET's Web site for the Company's use.
 
  In August 1998, Mr. Papermaster, a director of the Company, was granted an
option to purchase 25,000 shares of the Company's Common Stock at an exercise
price of $9.50 per share subject to a four year vesting schedule in connection

INDEMNIFICATION
 
  The Company's Certificate of Incorporation limits the liability of its
directors for monetary damages arising from a breach of their fiduciary duty
as directors, except to the extent otherwise required by the Delaware General
Corporation Law. 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 to the fullest extent permitted by Delaware law, including in
circumstances in which indemnification is otherwise discretionary under
Delaware law. The Company has also entered into indemnification agreements
with its officers and directors containing provisions that may require the
Company, among other things, to indemnify such officers and directors against
certain liabilities that may arise by reason of their status or service as
directors or officers
 
                                      53
<PAGE>
 
(other than liabilities arising from willful misconduct of a culpable nature),
to advance their expenses incurred as a result of any proceeding against them
as to which they could be indemnified, and to obtain directors' and officers'
insurance if available on reasonable terms.
 
  The Company believes that all of the transactions set forth above were made
on terms no less favorable to the Company than could have been obtained from
unaffiliated third parties. All future transactions, including loans between
the Company and its officers, directors, principal stockholders and their
affiliates will be approved by a majority of the Board of Directors, including
a majority of the independent and disinterested outside directors on the Board
of Directors, and will continue to be on terms no less favorable to the
Company than could be obtained from unaffiliated third parties.
 
PROTEGE SOFTWARE PROFESSIONAL SERVICES AGREEMENT
 
  In November 1997, the Company and Protege Software (Holdings) Limited
("Protege") entered into a professional services agreement (the "Professional
Services Agreement") under which Protege agreed to perform certain
professional services for the Company's European subsidiary, Vignette Europe
Ltd. ("Vignette Europe"). Protege provides Vignette Europe with its back-
office and administrative functions such as payroll, invoicing and accounting.
In addition, Protege provides general consulting services to Vignette Europe.
These services include assisting Vignette Europe with the development of its
business plans, implementation of its marketing strategy, localization of its
products and organization of training courses and seminars regarding the
Company's products. The Professional Services Agreement expires on December
31, 1998, and is automatically renewable for successive 12-month periods. It
may be terminated by either party, without cause, on three months' written
notice. Protege is in the business of providing similar services to technology
companies seeking to establish European operations.
 
  Under the terms of the Professional Services Agreement, the Company agreed
to pay Protege, in addition to its costs of providing the services, management
fees for the operations of Vignette Europe. Protege is entitled, at its
option, to convert up to 55% of a portion of the management fees into fully
paid voting stock of the Company at a price of $10.25 per share.
 
  Pany Christouforou, an employee of Protege, has served as the Company's Vice
President, Europe pursuant to the Professional Services Agreement since
January 1998.

                         DESCRIPTION OF CAPITAL STOCK
 
  On the closing of this offering, the authorized capital stock of the Company
will consist of 80,000,000 shares of Common Stock, $0.01 par value, and
10,000,000 shares of Preferred Stock, $0.01 par value.
 
COMMON STOCK
 
  As of November 30, 1998, there were 2,856,745 shares of Common Stock
outstanding that were held of record by approximately 150 stockholders. There
will be     shares of Common Stock outstanding (assuming no exercise of the
Underwriters' over-allotment option and assuming no exercise after November
30, 1998 of outstanding options) after giving effect to the sale of the shares
of Common Stock to the public offered hereby and the conversion of the
Company's Preferred Stock into Common Stock at a one-to-one ratio. The holders
of Common Stock are entitled to one vote per share on all matters to be voted
on by the stockholders. Subject to preferences that may be applicable to any
outstanding Preferred Stock, the holders of Common Stock are entitled to
receive ratably such dividends, if any, as may be declared from time to time
by the Board of Directors out of funds legally available therefor. 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 remaining after payment of liabilities, subject to prior
distribution rights of Preferred Stock, if any, then outstanding. The Common
Stock has no preemptive or conversion rights or other subscription rights.
There are no redemption or sinking fund provisions applicable to the Common
Stock. All outstanding shares of Common Stock are fully paid and
nonassessable, and the shares of Common Stock to be issued on completion of
this offering will be fully paid and nonassessable.
 
PREFERRED STOCK
 
  On the closing of this offering, 10,000,000 shares of Preferred Stock will
be authorized and no shares will be outstanding. The Board of Directors has
the authority to issue the Preferred Stock in one or more series and to fix
the 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 any series or the designation of such series, without
further vote or action by the stockholders. The issuance of Preferred Stock
may 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 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. At present, the Company has no plans to issue any of
the Preferred Stock.
 
ANTI-TAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION,
BYLAWS AND DELAWARE LAW
 
  Certificate of Incorporation and Bylaws
 
  The Company's Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") to be effective on the closing of this
offering provides that the Board of Directors will be divided into three
classes of directors, with each class serving a staggered three-year term. The
classification system of electing directors may tend to discourage a third
party from making a tender offer or otherwise attempting to obtain control of
the Company and may maintain the incumbency of the Board of Directors, as the
classification of the Board of Directors generally increases the difficulty of
replacing a majority of the directors. The Certificate of Incorporation also
provides that, effective on the closing of this offering, all stockholder
actions must be effected at a duly called meeting and not by a consent in
writing. Further, provisions of the Bylaws and the Certificate of
Incorporation provide that the stockholders may amend the Bylaws or certain
provisions of the Certificate of Incorporation only with the affirmative vote
of 75% of the Company's capital stock. These provisions of the Certificate of
Incorporation and Bylaws could discourage potential acquisition proposals and
could delay or prevent a change in control of the Company. These 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 that may
involve an actual or threatened change of control of the Company. These
provisions are designed to reduce the vulnerability of the Company to an
unsolicited acquisition proposal. The provisions also are intended to
discourage certain tactics that may be used
 
                                      57
<PAGE>
 
in proxy fights. However, such provisions could have the effect of
discouraging others from making tender offers for the Company's shares and, as
a consequence, they also may inhibit fluctuations in the market price of the
Company's shares that could result from actual or rumored takeover attempts.
Such provisions also may have the effect of preventing changes in the
management of the Company. See "Risk Factors--Anti-Takeover Provisions."
 
  Delaware Takeover Statute
 
  The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the date that
such stockholder became an interested stockholder, unless: (i) prior to such
date, the board of directors of the corporation approved either the business
combination or the transaction that resulted in the stockholder becoming an
interested stockholder; (ii) on consummation of the transaction that resulted
in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned (x) by persons
who are directors and also officers and (y) by employee stock plans in which
employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or
exchange offer; or (iii) on or subsequent to such date, the business
combination is approved by the board of directors and authorized at an annual
or special meeting of stockholders, and not by written consent, by the
affirmative vote of at least 66 2/3% of the outstanding voting stock that is
not owned by the interested stockholder.
 
  Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii)
any sale, transfer, pledge or other disposition of 10% or more of the assets
of the corporation involving the interested stockholder; (iii) subject to
certain exceptions, any transaction that results in the issuance or transfer
by the corporation of any stock of the corporation to the interested
stockholder; (iv) any transaction involving the corporation that has the
effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder; or
(v) the receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or
through the corporation. In general, Section 203 defines an interested
stockholder as any entity or person beneficially owning 15% or more of the
outstanding voting stock of the corporation and any entity or person
affiliated with or controlling or controlled by such entity or person.
 
REGISTRATION RIGHTS
 
  After this offering, the holders of approximately 10,115,500 shares of
Common Stock and rights to acquire 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 agreement between the Company and the holders of
such registrable securities, 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 security holders exercising registration rights, such holders
are entitled to notice of such registration and are entitled to include shares
of such Common Stock therein. Additionally, such holders are also entitled to
certain demand registration rights pursuant to which they may require the
Company on up to four occasions to file a registration statement under the
Securities Act at its 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 an unlimited
number of additional registration statements on Form S-3 at the Company's
expense. All of these registration rights are subject to certain conditions
and limitations, among them the right of the underwriters of an offering to
limit the number of shares included in such registration and the right of the
Company not to effect a requested registration within six months following an
offering of the Company's securities, including the offering made hereby. In
addition, the holders of registration rights have agreed not to exercise such
rights for at least 180 days after the offering without the prior written
consent of Morgan Stanley & Co. Incorporated.

</TABLE>
 
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least
one year is entitled to sell within any three-month period commencing 90 days
after the date of this Prospectus a number of shares that does not exceed the
greater of (i) 1% of the then outstanding shares of Common Stock
(approximately     shares immediately after the offering) or (ii) the average
weekly trading volume during the four calendar weeks preceding such sale,
subject to the filing of a Form 144 with respect to such sale. A person (or
persons whose shares are aggregated) who is not deemed to have been an
affiliate of the Company at any time during the 90 days immediately preceding
the sale who has beneficially owned his or her shares for at least two years
is entitled to sell such shares pursuant to Rule 144(k) without regard to the
limitations described above. Persons deemed to be affiliates must always sell
pursuant to Rule 144, even after the applicable holding periods have been
satisfied.
 
  The Company is unable to estimate the number of shares that will be sold
under Rule 144, since this will depend on the market price for the Common
Stock of the Company, the personal circumstances of the sellers and other
factors. Prior to this offering, there has been no public market for the
Common Stock, and there can be no assurance that a significant public market
for the Common Stock will develop or be sustained after the offering. Any
future sale of substantial amounts of the Common Stock in the open market may
adversely affect the market price of the Common Stock offered hereby.
 
  The Company, its directors, executive officers, stockholders with
registration rights and certain other stockholders have agreed pursuant to the
Underwriting Agreement and other agreements that they will not sell any Common
Stock without the prior consent of Morgan Stanley & Co. Incorporated for a
period of 180 days from the date of this Prospectus (the "180-day Lockup
Period"), except that the Company may, without such consent, grant options and
sell shares pursuant to the Company's stock plans.
 
  Any employee or consultant to the Company who purchased his or her shares
pursuant to a written compensatory plan or contract is entitled to rely on the
resale provisions of Rule 701, which permits nonaffiliates to sell their Rule
701 shares without having to comply with the public information, holding
period, volume limitation or notice provisions of Rule 144 and permits
affiliates to sell their Rule 701 shares without having to comply with the
Rule 144 holding period restrictions, in each case commencing 90 days after
the date of this Prospectus. As of the date of this Prospectus, the holders of
options exercisable into approximately 2,255,062 shares of Common Stock will
be eligible to sell their shares on the expiration of the 180-day Lockup
Period, or subject in certain cases to vesting of such options.
 
  The Company intends to file a registration statement on Form S-8 under the
Securities Act to register shares of Common Stock issued or reserved for
issuance under the Company's stock plans within 180 days after the date of
this Prospectus, thus permitting the resale of such shares by nonaffiliates in
the public market without restriction under the Securities Act. The Company
intends to register these shares on Form S-8, along with options that have not
been issued under the Company's stock plans as of the date of this Prospectus.

  In addition, after this offering, the holders of approximately 10,511,500
shares of Common Stock will be entitled to certain rights with respect to
registration of such shares under the Securities Act. Registration of such
shares under the Securities Act would result in such shares becoming freely
tradable without restriction under the Securities Act (except for shares
purchased by affiliates of the Company) immediately on the effectiveness of
such registration. See "Description of Capital Stock--Registration Rights."

  The underwriters are offering the shares subject to their acceptance of the
shares from the Company and the selling stockholders and subject to prior
sale. The Underwriting Agreement provides that the obligations of the several
underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The underwriters are obligated to
take and pay for all of the shares of Common Stock offered hereby (other than
those covered by the over-allotment option described below) if any such shares
are taken.
 
  The underwriters initially propose to offer part of the shares of Common
Stock directly to the public at the public offering price set forth on the
cover page hereof and part to certain dealers at a price that represents a
concession not in excess of $    a share under the public offering price. Any
underwriters may allow, and such dealers may reallow, a concession not in
excess of $    a share to other underwriters or to certain other dealers.
After the initial offering of the shares of Common Stock, the offering price
and other selling terms may from time to time be varied by the representatives
of the underwriters.
 
  Pursuant to the underwriting agreement, the Company has granted to the
underwriters an option, exercisable for 30 days from the date of this
prospectus, to purchase up to an aggregate of    additional shares of Common
Stock at the public offering price set forth on the cover page hereof, less
underwriting discounts and commissions. The underwriters may exercise such
option solely for the purpose of covering over-allotments, if any, made in
connection with the offering of the shares of Common Stock offered hereby. To
the extent such option is exercised, each underwriter will become obligated,
subject to certain conditions, to purchase approximately the same percentage
of such additional shares of Common Stock as the number set forth next to such
underwriter's name in the preceding table bears to the total number of shares
of Common Stock set forth next to the names of all underwriters in the
preceding table. If the underwriter's over-allotment option is exercised in
full, the total price to public would be $   , the total underwriters'
discounts and commissions would be $   , and the total proceeds to the Company
would be $   .
 
  At the request of the Company, the underwriters have reserved up to
shares of Common Stock to be issued by the Company and offered hereby for
sale, at the public offering price, to directors, officers, employees,
business associates and related persons of the Company. The number of shares
of Common Stock available for sale to the general public will be reduced to
the extent such individuals purchase such reserved
 
                                      61
<PAGE>
 
shares. Any reserved shares which are not so purchased will be offered by the
underwriters to the general public on the same basis as the other shares
offered hereby.
 
  Each of the Company, and the directors, officers and certain other
stockholders of the Company has agreed that, without the prior written consent
of Morgan Stanley & Co. Incorporated on behalf of the underwriters, during the
period ending 180 days after the date of this prospectus, it will not,
directly or indirectly (i) 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, lend or otherwise transfer or
dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock
(whether such shares or any such securities are then owned by such person or
are thereafter acquired directly from the Company), or (ii) enter into any
swap or other arrangement that transfers to another, in whole or in part, any
of the economic consequences of ownership of Common Stock, whether any such
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise. The
restrictions described in this paragraph do not apply to (a) the sale to the
underwriters of the shares of Common Stock under the underwriting agreement,
(b) the issuance by the Company of shares of Common Stock upon the exercise of
an option or a warrant or the conversion of a security outstanding on the date
of this prospectus of which the underwriters have been advised in writing, (c)
transactions by any person other than the Company relating to shares of Common
Stock or other securities acquired in open market transactions after the
completion of the offering of the shares of Common Stock or (d) issuances of
shares of Common Stock or options to purchase shares of Common Stock pursuant
to the Company's employee benefit plans as in existence on the date of the
Prospectus and consistent with past practices.
 
  The underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Common Stock offered by them.
 
  The Company has submitted an application to have its Common Stock approved
for quotation on the Nasdaq National Market under the symbol "VIGN."
 
  In order to facilitate the offering of the Common Stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the Common Stock
for their own account. In addition, to cover over-allotments or to stabilize
the price of the Common Stock, the underwriters may bid for, and purchase,
shares of Common Stock in the open market. Finally, the underwriting syndicate
may reclaim selling concessions allowed to an underwriter or a dealer for
distributing the Common Stock in the offering if the syndicate repurchases
previously distributed shares of Common Stock in transactions to cover
syndicate short positions, in stabilization transactions or otherwise. Any of
these activities may stabilize or maintain the market price of the Common
Stock above independent market levels. The underwriters are not required to
engage in these activities and may end any of these activities at any time.
 
  The Company, the selling stockholders and the underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.
 
  In April 1998, the Company sold shares of its Series F Preferred Stock in a
private placement. In this private placement, Hambrecht & Quist California
purchased 42,980 shares of Series F Preferred Stock, which are convertible
into 42,980 shares of Common Stock, for approximately $450,000 and H&Q
Vignette Investors L.P. purchased 100,287 shares of Series F Preferred Stock,
which are convertible into 100,287 shares of Common Stock, for approximately
$1.1 million. Hambrecht & Quist California and H&Q Vignette Investors, L.P.
purchased these shares on the same terms as the other investors in the private
placement. Hambrecht & Quist LLC, one of the underwriters in this offering, is
wholly owned by Hambrecht & Quist California. H&Q Vignette Investors, L.P. is
a California limited partnership with two general partners. One of the general
partners is a wholly owned subsidiary of Hambrecht & Quist California and the
other is a limited liability company of which two of the three members are
employees of Hambrecht & Quist LLC. In addition, approximately half of the
limited partners of H&Q Vignette Investors, L.P. are employees of Hambrecht &
Quist LLC or directors of Hambrecht & Quist Group, the parent corporation of
Hambrecht & Quist California.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
Vignette Corporation
 
  We have audited the accompanying consolidated balance sheets of Vignette
Corporation and Subsidiary as of December 31, 1996 and 1997, the related
consolidated statements of operations, changes in redeemable convertible
preferred stock and stockholders' equity (deficit) and cash flows for the
years then ended. 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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Vignette
Corporation and Subsidiary at December 31, 1996 and 1997, and the consolidated
results of their operations and their cash flows for the years then ended, in
conformity with generally accepted accounting principles.

                             VIGNETTE CORPORATION
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                              SEPTEMBER 30, 1998
                 (INFORMATION WITH RESPECT TO THE NINE MONTHS
                ENDED SEPTEMBER 30, 1997 AND 1998 IS UNAUDITED)
 
1. BUSINESS
 
  Vignette Corporation (the "Company") is a global provider of Internet
Relationship Management software products and services, a new category of
enterprise solutions designed to enable businesses to build sustainable online
customer relationships, increase returns on their Internet-related investments
and capitalize on Internet business opportunities. The consolidated financial
statements include the accounts of the Company and its wholly-owned foreign
subsidiary. All material intercompany accounts and transactions have been
eliminated in consolidation.
 
  The Company was incorporated in Delaware on December 19, 1995. Operations
for the period from December 19, 1995 to December 31, 1995 were not
significant.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The financial information for the nine months ended September 30, 1997 and
1998 is unaudited but includes all adjustments, consisting only of normal
recurring adjustments, which the Company considers necessary for a fair
presentation of the financial position, operating results and cash flows for
the period. Results for the nine months ended September 30, 1998 are not
necessarily indicative of the results for the entire year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates, and such
differences could be material to the financial statements.
 
 Revenue Recognition
 
  Revenue from license fees and from sales of software products is recognized
when persuasive evidence of an agreement exists, delivery of the product has
occurred, no significant Company obligations with regard to implementation
remain, the fee is fixed or determinable and collectibility is probable.
 
  Services revenue is primarily comprised of revenue from consulting fees,
maintenance agreements and training. Services revenue from consulting and
training billed on a time and materials basis is recognized as performed.
Services revenue on fixed price service arrangements is recognized upon
completion of specific contractual milestone events, or based on an estimated
percentage of completion as work progresses. Maintenance agreements include
the right to unspecified upgrades on an if-and-when available basis.
Maintenance revenue is deferred and recognized on a straight-line basis as
services revenue over the life of the related agreement, which is typically
one year.
 
  Customer advances and billed amounts due from customers in excess of revenue
recognized are recorded as deferred revenue.
 
  The Company adopted Statement of Position 97-2, Software Revenue Recognition
("SOP 97-2") and Statement of Position 98-4, Deferral of the Effective Date of
a Provision of SOP 97-2, Software Revenue Recognition ("SOP 98-4") as of
January 1, 1998. SOP 97-2 and SOP 98-4 provide guidance for recognizing
revenue on software transactions and supersede SOP 91-1. The adoption of SOP
97-2 and SOP 98-4 did not have a material impact on the Company's financial
results. However, full implementation guidelines for this standard have not
yet been issued. Once available, our current revenue accounting practices may
need to change and such changes could affect our future revenues and earnings.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
 Cash Equivalents
 
  Cash equivalents consist primarily of cash deposits and investments with
original maturities of ninety days or less when purchased.
 
 Property and Equipment
 
  Property and equipment are carried at cost less accumulated depreciation.
Depreciation of property and equipment is computed using the straight-line
method over the useful lives of the assets (generally 1.5 to 3 years).
Amortization of assets recorded under capital leases is computed using the
straight-line method over the shorter of the asset's useful life or the term
of the lease and such amortization is included with depreciation expense.
 
 Research and Development
 
  Research and development expenditures are expensed to operations as
incurred. Statement of Financial Accounting Standards No. 86, Accounting for
the Costs of Computer Software to be Sold, Leased or Otherwise Marketed,
requires capitalization of certain software development costs subsequent to
the establishment of technological feasibility. Based on the Company's product
development process, technological feasibility is established upon completion
of a working model. Costs incurred by the Company between completion of the
working model and the point at which the product is ready for general release
have been insignificant. Through September 30, 1998, all software development
costs have been expensed.
 
 Advertising Costs
 
  The Company expenses advertising costs as incurred. These expenses were
approximately $1,000 and $158,000 for the years ended December 31, 1996 and
1997, respectively, and $-0- and $50,000 for the nine months ended September
30, 1997 and 1998, respectively.
 
 Income Taxes
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards (SFAS) No. 109, Accounting for Income Taxes.
This Statement prescribes the use of the liability method whereby deferred tax
asset and liability account balances are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.
 
 Foreign Currency Transactions
 
  For the Company's foreign subsidiary, the functional currency has been
determined to be the local currency, and therefore, assets and liabilities are
translated at year end or period end exchange rates, and income statement
items are translated at average exchange rates prevailing during the year or
period. Such translation adjustments are recorded in aggregate as a component
of stockholders' equity. Gains and losses from foreign currency denominated
transactions are included in other income (expense) and are not material. No
foreign operations existed for the year ended December 31, 1996 or for nine
months ended September 30, 1997.
 
 Stock-Based Compensation
 
  FASB Statement No. 123, Accounting for Stock-Based Compensation, (SFAS 123)
prescribes accounting and reporting standards for all stock-based compensation
plans, including employee stock options. As allowed by SFAS 123, the Company
has elected to continue to account for its employee stock-based compensation
in accordance with Accounting Principles Board Opinion No. 25, Accounting for
Stock Issued to Employees (APB 25).
 
 Concentration of Credit Risk
 
  Financial instruments which potentially subject the Company to
concentrations of credit risk consist of short-term investments and trade
receivables. The Company's short-term investments, which are included in cash

  Customers A and B accounted for 13% and 11%, respectively, of the Company's
total revenue for the year ended December 31, 1997. No customers accounted for
more than 10% of the Company's total revenue during the nine months ended
September 30, 1998.
 
 Net Loss Per Share
 
  The Company follows the provisions of Statement of Financial Accounting
Standards No. 128, Earnings Per Share (SFAS 128). Basic net loss per share is
computed by dividing net loss available to common stockholders by the weighted
average number of common shares outstanding during the period. Diluted net
loss per share has not been presented as the effect of the assumed exercise of
stock options, warrants and contingently issued shares is antidilutive due to
the Company's net loss.
 
  The Company's historical capital structure is not indicative of its
prospective structure due to the automatic conversion of all shares of
Convertible Preferred Stock and Redeemable Convertible Preferred Stock into
Common Stock concurrent with the closing of the Company's anticipated initial
public offering. Accordingly, a pro forma calculation assuming the conversion
of all outstanding shares as of September 30, 1998 of Convertible Preferred
Stock and Redeemable Convertible Preferred Stock into Common Stock upon the
Company's initial public offering using the if-converted method from their
respective dates of issuance is presented.

net loss per share (in thousands, except per share data):

 Voting Rights
 
  Each share of Common Stock has one voting right. Each series of Redeemable
Convertible Preferred Stock and Convertible Preferred Stock have voting rights
equal to the number of common shares into which all shares of a particular
series of Preferred Stock could then be converted.
 
 Stock Option/Stock Issuance Plan
 
  The Company has a 1995 Stock Option/Stock Issuance Plan (the "Plan") whereby
employees, members of the Board of Directors, and independent advisors may be
granted options to purchase shares of the Company's Common Stock or may be
issued shares of the Company's Common Stock directly. Options are immediately
exercisable subject to a repurchase agreement. The stock options and the
related exercised stock will generally vest over a four year cumulative
period. The term of each option is no more than ten years from the date of
grant. Options authorized under the Plan were 5,061,000 at September 30, 1998.
Stock issuances may be for purchase or as a bonus for services rendered to the
Company.
 
  Upon certain events, the Company has repurchase rights for unvested shares
equal to the original exercise price. The Company also has the right of first
refusal for any proposed disposition of shares issued under the Plan.
 
  In 1998, the Company recorded total deferred stock compensation of $524,000
in connection with stock options granted during the nine months ended
September 30, 1998. Such amount is being amortized over the vesting periods of
the applicable options, resulting in amortization of $142,000 for the nine
months ended September 30, 1998. These amounts represent the difference
between the exercise price of certain stock option grants and the deemed fair
value of the Company's Common Stock at the time of such grants.

  Rent expense for the years ended December 31, 1996 and 1997 and for the nine
months ended September 30, 1998 was $95,000, $263,000 and $931,000,
respectively.
 
6. INCOME TAXES
 
  As of December 31, 1997, the Company had net operating loss and research and
development credit carryforwards of approximately $9,770,000 and $92,000,
respectively. The net operating loss and credit carryforwards will expire at
various dates, beginning in 2011, if not utilized.
 
  The Tax Reform Act of 1986 imposes substantial restrictions on the
utilization of net operating losses and tax credits in the event of an
"ownership change" of a corporation. The Company's utilization of the net
operating losses will be subject to a substantial annual limitation due to an
"ownership change" resulting from the sales of private equity securities. The
annual limitation may result in the expiration of net operating losses before
utilization.
 
  Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components
of the Company's deferred taxes as of December 31, 1996 and 1997 and as of
September 30, 1998 are as follows (in thousands):

6. INCOME TAXES (CONTINUED)
 
  The Company has established a valuation allowance equal to the net deferred
tax asset due to uncertainties regarding the realization of deferred tax
assets based on the Company's lack of earnings history. The valuation
allowance increased by approximately $2,805,000 during the year ended December
31, 1997 and $5,325,000 during the nine months ended September 30, 1998.
 
  Undistributed earnings of the Company's foreign subsidiary were immaterial
as of December 31, 1997. Those earnings are considered to be permanently
reinvested and, accordingly, no provision for U.S. federal and/or state income
taxes has been provided thereon.
 
  The Company's provision for income taxes differs from the expected tax
benefit amount computed by applying the statutory federal income tax rate of
34% to income before income taxes as a result of the following:

7. ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT
 
  During May 1998, the Company acquired from RandomNoise, Inc. certain in-
process research and development effort, a developed product and an
insignificant amount of equipment in exchange for $100,000 in cash and 191,022
shares of the Company's Series G Convertible Preferred Stock valued at $10.47
share or $2,000,000. Substantially all of the $2,100,000 purchase price was
allocated to the acquired in-process research and development efforts based
upon the following: (i) the Company assigned no value to the developed product
as the Company does not intend to sell, support or enhance such product and
the Company believes it has no alternative future use; (ii) the $10.47 per
share ascribed to the Company's Series G Convertible Preferred Stock was based
on the value per share received from the issuance of Series F Redeemable
Convertible Preferred Stock, which occurred in April 1998; and (iii) the
allocation of the entire $2,100,000 purchase price was determined to be
reasonable based on the Company's estimate of costs it would incur if it had
performed this effort internally. The in-process research and development
effort relates to the development of visual development tool technology using
graphical user interface ("GUI") technology not possessed by the Company and
at the time of purchase the results of the in-process research and development
effort had not progressed to a stage where they met technological feasibility.
 
  During July 1996, the Company acquired from CNET, certain software related
to intellectual property rights for 1,865,000 shares of the Company's Series C
Convertible Preferred Stock valued at $1,865,000. The technology purchased
from CNET lacked many key elements essential to the ultimate product to be
released by the Company such as an enhanced user interface, expansion to
additional database platforms, an automated install feature, and automated
testing capabilities. These key elements were subsequently developed by the
Company and led to a beta product released in December 1996. All of the
$1,865,000 purchase price was allocated to acquired in-process research and
development efforts.

plan (the "401(k) Plan") qualifying under Section 401(k) of the Internal
Revenue Code of 1986. The Company made no contributions in the year ended
December 31, 1997 or in the nine months ended September 30, 1998.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's Board of Directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). Article VII, Section 6, of the Registrant's
Bylaws provides for mandatory indemnification of its directors and officers
and permissible indemnification of employees and other agents to the maximum
extent permitted by the Delaware General Corporation Law. The Registrant's
Certificate of Incorporation provides that, pursuant to Delaware law, its
directors shall not be liable for monetary damages for breach of the
directors' fiduciary duty as directors to the Company and its stockholders.
This provision in the Certificate of Incorporation does not eliminate the
directors' fiduciary duty, and in appropriate circumstances equitable remedies
such as injunctive or other forms of non-monetary relief will remain available
under Delaware law. In addition, each director will continue to be subject to
liability for breach of the director's duty of loyalty to the Company for acts
or omissions not in good faith or involving intentional misconduct, for
knowing violations of law, for actions leading to improper personal benefit to
the director, and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under Delaware law. The provision also does not
affect a director's responsibilities under any other law, such as the federal
securities laws or state or federal environmental laws. The Registrant has
entered into Indemnification Agreements with its officers and directors, a
form of which is attached as Exhibit 10.1 hereto and incorporated herein by
reference. The Indemnification Agreements provide the Registrant's officers
and directors with further indemnification to the maximum extent permitted by
the Delaware General Corporation Law. Reference is made to the Underwriting
Agreement contained in Exhibit 1.1 hereto, which contains provisions
indemnifying officers and directors of the Registrant against certain
liabilities.

ITEM 17. UNDERTAKINGS
 
  The Registrant hereby undertakes to provide to 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
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the Delaware General Corporation Law, the Certificate
of Incorporation or the Bylaws of the Registrant, the Underwriting Agreement,
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
hereunder, 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 of whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
 
  The Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance on Rule 430A and contained in a 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.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective 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.

     Part 1.  Dividends.

     1A.  (i)   From and after January 1, 1999, (a) the holders of the then
outstanding Series A Preferred Stock shall be entitled to receive, when and as
declared by the Board, and out of any funds legally available therefor,
cumulative dividends at the annual rate of $0.06 per share, (b) the holders of
the then outstanding Series B Preferred Stock shall be entitled to receive, when
and as declared by the Board, and out of any funds legally available therefor,
cumulative dividends at the annual rate of $0.10 per share and (c) the holders
of the then outstanding Series C Preferred Stock shall be entitled to receive,
when and as declared by the Board, and out of any funds legally available
therefor, cumulative dividends at the annual rate of $0.06 per share.  Dividends
on the shares of Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock shall accumulate and accrue on each such share from January 1,
1999 and shall accumulate and accrue from day to day thereafter, whether or not
earned or declared.  Such dividends shall be cumulative so that, except as
provided in paragraph 1B, if such dividends in respect of any previous or
current quarterly dividend period, at the annual rate specified above, shall not
have been paid or declared and a sum sufficient for the payment thereof set
apart, the deficiency shall first be fully paid before any dividend or other
distribution shall be paid or declared and set apart for the Common Stock.

          (ii)  The holders of the outstanding Series D Preferred Stock shall be
entitled to receive dividends on such shares when and as declared by the Board,
and out of any funds legally available therefor; provided, however, that
dividends shall accumulate and accrue at the same time or times and the same
rate as dividends are paid on the Corporation's outstanding Common Stock.
Dividends payable with respect to the Series D Preferred Stock shall be non-

of the Corporation legally available for distribution shall be distributed
ratably among the holders of the Series A Preferred Stock, Series B Preferred

C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock, Series F
Preferred Stock and Series H Preferred Stock pursuant to paragraph 2A, the
assets and funds thus distributed among the holders of the Series G Preferred
Stock shall be insufficient to permit the payment to such holders of Series G
Preferred Stock of the full respective preferential amounts due with respect to
the shares held by each such holder, then the entire assets and funds of the
Company legally available for distribution remaining after such distribution
pursuant to paragraph 2A shall be distributed ratably among the holders of the
Series G Preferred Stock in proportion to the shares of Series G Preferred Stock
then held by them.

on the date on which the certificate or certificates representing the shares of
such Preferred Stock to be converted, together with properly executed conversion
instructions or powers, have been surrendered for conversion at the principal
office of the Corporation.  At such time as such conversion has been effected,
the rights of the holder of such shares of Preferred Stock as such holder will
cease and the Person or Persons in whose name or names any certificate or
certificates for shares of Common Stock are to be issued upon such conversion
will be deemed to have become the holder or holders of record of the shares of
Common Stock represented thereby.

          (iii) As soon as possible after a conversion has been effected (but
in any event within three business days in the case of subparagraph (a) below),
the Corporation will deliver to the converting holder:

                (a) a certificate or certificates representing the number of
shares of Common Stock issuable by reason of such conversion in such name or
names and such denomination or denominations as the converting holder has
specified; and

                (b) a certificate representing any shares of Preferred Stock
which were represented by the certificate or certificates delivered to the
Corporation in connection with such conversion but which were not converted.

          (iv)  The issuance of certificates for shares of Common Stock upon
conversion of shares of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock,
Series F Preferred Stock, Series G Preferred Stock or Series H Preferred Stock
will be made without charge to the holders of such shares of Preferred Stock for
any issuance tax in respect thereof or other cost incurred by the Corporation in
connection with such conversion and the related issuance of shares of Common
Stock.  Upon conversion of each share of each such series of Preferred Stock,
the Corporation will take all such actions as are necessary in order to insure
that the Common Stock issuable with respect to such conversion will be validly
issued, fully paid and nonassessable.

          (v)   If any fractional interest in a share of Common Stock would,
except for the provisions of this subparagraph (v), be deliverable upon any
conversion of shares of Series A Preferred Stock, Series B Preferred Stock,
Series E Preferred Stock, Series F Preferred Stock, Series G Preferred Stock or
Series H Preferred Stock the Corporation, in lieu of delivering the 

                                       12

fractional share therefor, will pay an amount to the holder thereof equal to the
Fair Market Value of such fractional interest as of the date of conversion.

     5B.  Conversion Price.

          (i)   The initial "Series A Conversion Price" will be $1.00 per share
of Series A Preferred Stock. The initial "Series B Conversion Price" will be
$1.65 per share of Series B Preferred Stock. The initial "Series C Conversion
Price" will be $1.00 per share of Series C Preferred Stock. The initial "Series
D Conversion Price" will be $1.65 per share of Series D Preferred Stock. The
initial "Series E Conversion Price" will be $4.24 per share of Series E
Preferred Stock. The initial "Series F Conversion Price" will be $10.47 per
share of Series F Preferred Stock. The initial "Series G Conversion Price" will
be $10.47 per share of Series G Preferred Stock. The initial "Series H
Conversion Price" will be $16.33 per share of Series H Preferred Stock. In order
to prevent dilution of the conversion rights granted under this subdivision, the
Series A Conversion Price, the Series B Conversion Price, the Series E
Conversion Price, the Series F Conversion Price and the Series H Conversion
Price (but not the Series C Conversion Price, the Series D Conversion Price or
the Series G Conversion Price) also will be subject to adjustment from time to
time pursuant to this part 5B.

          (ii)  If and whenever on or after the date hereof, the Corporation
issues or sells, or is deemed to have issued or sold, any shares of its Common
Stock for consideration per share less than the Series A Conversion Price in
effect immediately prior to the time of such issue or sale, then immediately
upon such issue or sale the Series A Conversion Price will be reduced to the
price determined by multiplying the Series A Conversion Price then in effect by
a fraction, the numerator of which shall be (a) the number of shares of Common
Stock outstanding immediately prior to such issue or sale, plus (b) the number
of shares of Common Stock which the aggregate consideration received by the
Corporation for the total number of additional shares of Common Stock so issued
or sold would purchase at such Series A Conversion Price, and the denominator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such issue or sale plus the number of additional shares of Common Stock
so issued.  For example, if there are 1,600,000 shares of Common Stock
outstanding and, after the date hereof, the Corporation issues 1,000,000 shares
of Common Stock for consideration per share of $0.50, the Series A Conversion
Price immediately would be reduced to the price determined by multiplying $1.00,
the Series A Conversion Price then in effect, by the following fraction:

              1,600,000.00  +      $  500,000.00
                              ------------------
                                   $        1.00
         ---------------------------------------
              1,600,000.00  +          1,000,000

       =      1,600,000.00  +         500,000.00
         ---------------------------------------
                                       2,600,000

       =                            2,100,000.00
                              ------------------
                                       2,600,000

       =           0.8077,

                                       13
<PAGE>
 
resulting in an adjusted Series A Conversion Price of $0.8077 ($1.00 x 0.8077).
The following transactions shall not result in any adjustment of the Series A
Conversion Price: (i) the issuance of Common Stock and the grant of options,
warrants or rights and the issuance of Common Stock upon exercise thereof
pursuant to any Approved Plan; (ii) the grant of warrants and the issuance of
Common Stock upon exercise thereof pursuant to paragraph 8E(ii)(c) of the
February Purchase Agreement; (iii) the issuance of shares of the Corporation's
Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and
Series E Preferred Stock and the issuance of Common Stock upon conversion
thereof and (iv) the issuance of Common Stock upon conversion of the Series A
Preferred Stock.

          (iii) If and whenever on or after the date hereof, the Corporation
issues or sells, or is deemed to have issued or sold, any shares of its Common
Stock for consideration per share less than the Series B Conversion Price in
effect immediately prior to the time of such issue or sale, then immediately
upon such issue or sale the Series B Conversion Price will be reduced to the
price determined by multiplying the Series B Conversion Price then in effect by
a fraction, the numerator of which shall be (a) the number of shares of Common
Stock outstanding immediately prior to such issue or sale, plus (b) the number
of shares of Common Stock which the aggregate consideration received by the
Corporation for the total number of additional shares of Common Stock so issued
or sold would purchase at such Series B Conversion Price, and the denominator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such issue or sale plus the number of additional shares of Common Stock
so issued.  For example, if there are 1,600,000 shares of Common Stock
outstanding and, after the date hereof, the Corporation issues 1,000,000 shares
of Common Stock for consideration per share of $0.50, the Series B Conversion
Price immediately would be reduced to the price determined by multiplying $1.65,
the Series B Conversion Price then in effect, by the following fraction:

              1,600,000.00   +      $  500,000.00
                               ------------------
                                    $        1.65
         ----------------------------------------
              1,600,000.00   +          1,000,000

        =     1,600,000.00   +         303,030.30
         ----------------------------------------
                                        2,600,000

        =                            1,903,030.30
                               ------------------
                                        2,600,000

        =          0.7319,

resulting in an adjusted Series B Conversion Price of $1.21 ($1.65 x 0.7319).
The following transactions shall not result in any adjustment of the Series B
Conversion Price: (i) the issuance of Common Stock and the grant of options,
warrants or rights and the issuance of Common Stock upon exercise thereof
pursuant to any Approved Plan; (ii) the issuance of shares of the Corporation's
Series A Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and
Series E Preferred Stock and the issuance of Common Stock upon conversion
thereof and (iii) the issuance of Common Stock upon conversion of the Series B
Preferred Stock.

          (iv)  (a)  If and whenever on or after the date hereof, the
Corporation issues or sells, or is deemed to have issued or sold, any shares of
its Common Stock for consideration per share less than the Series E Conversion
Price in effect immediately prior to the time of such issue or sale, then
immediately upon such issue or sale the Series E Conversion Price will be
reduced to the price determined by multiplying the Series E Conversion Price
then in effect by a fraction, the numerator of which shall be (a) the number of
shares of Common Stock outstanding immediately prior to such issue or sale, plus
(b) the number of shares of Common Stock which the aggregate consideration
received by the Corporation for the total number of additional shares of Common
Stock so issued or sold would purchase at such Series E Conversion Price, and
the denominator of which shall be the number of shares of Common Stock
outstanding immediately prior to such issue or sale plus the number of
additional shares of Common Stock so issued. For example, if there are 1,600,000
shares of Common Stock outstanding and, after the date hereof, the Corporation
issues 1,000,000 shares of Common Stock for consideration per share of $0.50,
the Series E Conversion Price immediately would be reduced to the price
determined by multiplying $4.24, the Series E Conversion Price then in effect,
by the following fraction:

              1,600,000.00   +      $  500,000.00
                               ------------------
                                    $        4.24
         ----------------------------------------
              1,600,000.00   +          1,000,000

        =     1,600,000.00   +         117,924.53
         ----------------------------------------
                                        2,600,000

        =                            1,717,924.53
                               ------------------
                                        2,600,000

        =          0.6607,

resulting in an adjusted Series E Conversion Price of $2.80 ($4.24 x 0.6607).
The following transactions shall not result in any adjustment of the Series E
Conversion Price: (i) the issuance of Common Stock and the grant of options,
warrants or rights and the issuance of Common Stock upon exercise thereof
pursuant to any Approved Plan; (ii) the issuance of shares of Common Stock upon
conversion of the Corporation's Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock and Series D Preferred Stock; (iii) the issuance
of up to 7,500 shares of the Corporation's Series A Preferred Stock and up to
65,368 shares of the Corporation's Series D Preferred Stock pursuant to
outstanding warrants and the issuance of Common Stock upon conversion thereof
and (iv) the issuance of Common Stock upon conversion of the Series E Preferred
Stock.

                (b)  Notwithstanding the foregoing subparagraph (a), if (X) the
gross proceeds of sales of Series E Preferred Stock on or within 60 days
following June 6, 1997 are less than $6,000,000 and (Y) prior to the earlier of
(1) June 6, 1998 or (2) a subsequent equity financing of the Corporation at a
price per share of at least $4.24 and in which the gross proceeds to the
Corporation are at least $4,000,000, the Corporation issues or sells, or is
deemed to have issued or sold, any shares of its Common Stock for consideration
per share less than the Series E Conversion

Price in effect immediately prior to the time of such issue or sale (a "Lesser
Issuance"), then immediately upon such Lesser Issuance the Series E Conversion
Price will be reduced to a price equal to the price paid per share in such
Lesser Issuance; provided, however, that the following transactions shall not
result in any adjustment of the Series E Conversion Price: (i) the issuance of
Common Stock and the grant of options, warrants or rights and the issuance of
Common Stock upon exercise thereof pursuant to any Approved Plan; (ii) the
issuance of shares of Common Stock upon conversion of the Corporation's Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock; (iii) the issuance of up to 7,500 shares of the Corporation's
Series A Preferred Stock and up to 65,368 shares of the Corporation's Series D
Preferred Stock pursuant to outstanding warrants and the issuance of Common
Stock upon conversion thereof and (iv) the issuance of Common Stock upon
conversion of the Series E Preferred Stock; and provided, further, that the
provisions of this subparagraph (b) shall apply to each Lesser Issuance until
the occurrence of the first Lesser Issuance, if any, in which the gross proceeds
to the Corporation are at least $4,000,000. The adjusted Series E Conversion
Price following any subsequent Lesser Issuance shall be determined by the
foregoing subparagraph (a).

          (v)   (a)  Subject to the application of subsection (v)(b) below, if
and whenever on or after the date hereof, the Corporation issues or sells, or is
deemed to have issued or sold, any shares of its Common Stock for consideration
per share less than the Series F Conversion Price in effect immediately prior to
the time of such issue or sale, then immediately upon such issue or sale the
Series F Conversion Price will be reduced to the price determined by multiplying
the Series F Conversion Price then in effect by a fraction, the numerator of
which shall be (a) the number of shares of Common Stock outstanding immediately
prior to such issue or sale, plus (b) the number of shares of Common Stock which
the aggregate consideration received by the Corporation for the total number of
additional shares of Common Stock so issued or sold would purchase at such
Series F Conversion Price, and the denominator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issue or sale plus
the number of additional shares of Common Stock so issued.  For example, if
there are 1,600,000 shares of Common Stock outstanding and, after the date
hereof, the Corporation issues 1,000,000 shares of Common Stock for
consideration per share of $0.50, the Series F Conversion Price immediately
would be reduced to $8.38 per share pursuant to subparagraph (v)(b) below and
would be further reduced pursuant to this subparagraph (v)(a) to the price
determined by multiplying $8.38, the Series F Conversion Price then in effect,
by the following fraction:

               1,600,000   +      $  500,000.00
                             ------------------
                                  $        8.38
         --------------------------------------
               1,600,000   +          1,000,000

        =      1,600,000   +          59,665.87
         --------------------------------------
                                      2,600,000

        =                          1,659,665.87
                             ------------------
                                      2,600,000

        =        0.6383,

                                       16
<PAGE>
 
resulting in an adjusted Series F Conversion Price of $5.35 ($8.38 x 0.6383).
The following transactions shall not result in any adjustment of the Series F
Conversion Price: (i) the issuance of Common Stock and the grant of options,
warrants or rights and the issuance of Common Stock upon exercise thereof
pursuant to any Approved Plan; (ii) the issuance of shares of Common Stock upon
conversion of the Corporation's Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred
Stock; (iii) the issuance of up to 7,500 shares of the Corporation's Series A
Preferred Stock and up to 65,368 shares of the Corporation's Series D Preferred
Stock pursuant to outstanding warrants and the issuance of Common Stock upon
conversion thereof and (iv) the issuance of Common Stock upon conversion of the
Series F Preferred Stock.

                (b)  If at any time during which the Series F Conversion Price
is greater than $8.38 the Corporation shall issue additional shares of Common
Stock without consideration or for a consideration per share less than the
Series F Conversion Price in effect on the date of and immediately prior to such
issue, then and in such event, such Series F Conversion Price shall be reduced,
concurrently with such issue, to a price equal to the greater of (i) the price
per share for such additional shares of Common Stock or (ii) $8.38. In the event
that the price per share for such additional shares of Common Stock is lower
than $8.38, then the Series F Conversion Price shall first be adjusted to $8.38
pursuant to this subsection (b), and any additional adjustment shall be made
pursuant to the provisions of subsection (a). For example, if 1,000,000
additional shares of Common Stock are issued at price per share of $5.00 at a
time when the Series F Conversion Price is $10.47, then (x) the Series F
Conversion Price shall first be reduced to $8.38 pursuant to the application of
this subsection (b), then (y) the Series F Conversion Price (as so adjusted)
shall be subject to further adjustment under subsection (a) above, assuming an
initial Series F Conversion Price of $8.38 for the purposes of applying the
formula required thereby. All per share prices in this subsection shall be
appropriately adjusted to reflect any stock dividends, combinations or splits
with respect to such shares.

          (vi)  (a)  If and whenever on or after the date hereof, the
Corporation issues or sells, or is deemed to have issued or sold, any shares of
its Common Stock for consideration per share less than the Series H Conversion
Price in effect immediately prior to the time of such issue or sale, then
immediately upon such issue or sale the Series H Conversion Price will be
reduced to the price determined by multiplying the Series H Conversion Price
then in effect by a fraction, the numerator of which shall be (a) the number of
shares of Common Stock outstanding immediately prior to such issue or sale, plus
(b) the number of shares of Common Stock which the aggregate consideration
received by the Corporation for the total number of additional shares of Common
Stock so issued or sold would purchase at such Series H Conversion Price, and
the denominator of which shall be the number of shares of Common Stock
outstanding immediately prior to such issue or sale plus the number of
additional shares of Common Stock so issued. For example, if there are 1,600,000
shares of Common Stock outstanding and, after the date hereof, the Corporation
issues 1,000,000 shares of Common Stock for consideration per share of $0.50,
the Series H Conversion Price immediately would be reduced to the price
determined by multiplying $16.33, the Series H Conversion Price then in effect,
by the following fraction:

              1,600,000.00  +      $  500,000.00

         ---------------------------------------
              1,600,000.00  +          1,000,000

        =     1,600,000.00  +          30,618.49
         ---------------------------------------
                                       2,600,000

        =                           1,630,618.49
                              ------------------
                                       2,600,000

        =           .6272,

resulting in an adjusted Series H Conversion Price of $10.24 ($16.33 x .6272).
The following transactions shall not result in any adjustment of the Series H
Conversion Price: (i) the issuance of Common Stock and the grant of options,
warrants or rights and the issuance of Common Stock upon exercise thereof
pursuant to any Approved Plan; (ii) the issuance of Common Stock upon conversion
of the Corporation's Series A Preferred Stock, Series B Preferred Stock, Series
C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock, Series F
Preferred Stock, and Series G Preferred Stock and (iii) the issuance of Common
Stock upon conversion of the Series H Preferred Stock.


                (b)  (i)   If, on or prior to June 30, 1999, the Corporation
issues shares of Common Stock (or securities convertible into or exchangeable
for Common Stock) in its first underwritten offering by the Corporation of
shares of Common Stock to the public pursuant to an effective registration
statement under the Securities Act of 1933, as amended, then in effect, or any
comparable statement under any similar federal statute then in effect (an
"IPO"), the Series H Conversion Price will be adjusted to the greater of $10.47
and a price equal to 80% of the per share IPO price; provided, however, that the
Series H Conversion Price will not be adjusted to a number greater than a price
equal to $230 million divided by the number of shares of Common Stock of the
Corporation then outstanding (assuming the conversion or exchange of all
outstanding securities convertible into or exchangeable for Common Stock of the
Corporation, the issuance of all shares reserved for issuance under an Approved
Plan and the exercise of all outstanding warrants to purchase capital stock of
the Corporation but excluding the shares issued by the Corporation in the IPO)
(for purposes of this subsection (b), the "Fully Diluted Shares Outstanding").

                     (ii)  If the Corporation completes the IPO after June 30,
1999 the Series H Conversion Price will be adjusted to the greater of $10.47 and
a price equal to (x) the sum of (1) $137 million and (2) the product of .40611
and the amount by which the valuation of the Corporation in the IPO exceeds $171
million, divided by (y) the Fully Diluted Shares Outstanding; provided, however,
that the Series H Conversion Price will not be adjusted to a number greater than
a price equal to $230 million divided by the Fully Diluted Shares Outstanding.

                     (iii) Adjustments made pursuant to the provisions of this
subsection (b) shall be effective immediately prior to the IPO and shall be made
before giving effect to any additional adjustments in connection with the IPO
pursuant to subsection (a).

<PAGE>
 
                     (iv)  For purposes of this subsection (b), the valuation of
the Corporation in the IPO is equal to the product of (A) the per share IPO
price and (B) the Fully Diluted Shares Outstanding.

     5C.  Effect on Conversion Price of Certain Events.  For purposes of
determining the adjusted Series A Conversion Price, Series B Conversion Price,
Series E Conversion Price, Series F Conversion Price and Series H Conversion
Price under paragraph 5B, the following will be applicable:

          (i) If the Corporation in any manner grants any Options or Options to
purchase Convertible Securities and the price per share for which Common Stock
is issuable upon the exercise of such Options or upon conversion or exchange of
such Convertible Securities is less than the Series A Conversion Price in effect
immediately prior to the time of the granting of such Options, then the total
maximum number of shares of Common Stock issuable upon the exercise of such
Options or upon conversion or exchange of the total maximum amount of such
Convertible Securities issuable upon the exercise of such Options will be deemed
to be outstanding and to have been issued and sold by the Corporation for such
price per share.  If the Corporation in any manner grants any Options or Options
to purchase Convertible Securities and the price per share for which Common
Stock is issuable upon the exercise of such Options or upon conversion or
exchange of such Convertible Securities is less than the Series B Conversion
Price in effect immediately prior to the time of the granting of such Options,
then the total maximum number of shares of Common Stock issuable upon the
exercise of such Options or upon conversion or exchange of the total maximum
amount of such Convertible Securities issuable upon the exercise of such Options
will be deemed to be outstanding and to have been issued and sold by the
Corporation for such price per share. If the Corporation in any manner grants
any Options or Options to purchase Convertible Securities and the price per
share for which Common Stock is issuable upon the exercise of such Options or
upon conversion or exchange of such Convertible Securities is less than the
Series E Conversion Price in effect immediately prior to the time of the
granting of such Options, then the total maximum number of shares of Common
Stock issuable upon the exercise of such Options or upon conversion or exchange
of the total maximum amount of such Convertible Securities issuable upon the
exercise of such Options will be deemed to be outstanding and to have been
issued and sold by the Corporation for such price per share. If the Corporation
in any manner grants any Options or Options to purchase Convertible Securities
and the price per share for which Common Stock is issuable upon the exercise of
such Options or upon conversion or exchange of such Convertible Securities is

of the granting of such Options, then the total maximum number of shares of
Common Stock issuable upon the exercise of such Options or upon conversion or
exchange of the total maximum amount of such Convertible Securities issuable
upon the exercise of such Options will be deemed to be outstanding and to have
been issued and sold by the Corporation for such price per share. If the

Securities and the price per share for which Common Stock is issuable upon the
exercise of such Options or upon conversion or exchange of such Convertible
Securities is less than the Series H Conversion Price in effect immediately
prior to the time of the granting of such Options, then the total maximum number
of shares of Common Stock issuable upon the exercise of such Options or upon

Securities issuable upon the exercise of such Options will be deemed to be
outstanding and to have been issued and sold by

                                       19

the Corporation for such price per share. For purposes of this paragraph, the
"price per share for which Common Stock is issuable" will be determined by
dividing (a) the total amount, if any, received or receivable by the Corporation
as consideration for the granting of such Options, plus the minimum aggregate
amount of additional consideration payable to the Corporation upon exercise of
all such Options, plus, in the case of such Options which relate to Convertible
Securities, the minimum aggregate amount of additional consideration, if any,
payable to the Corporation upon the issuance of sale or such Convertible
Securities and the conversion or exchange thereof, by (b) the total maximum
number of shares of Common Stock issuable upon the exercise of such Options and
upon the conversion or exchange of all such Convertible Securities issuable upon
the exercise of such Options. No further adjustment of the Series A Conversion
Price will be made when Convertible Securities are actually issued upon the
exercise of such Options or when Common Stock is actually issued upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities. No further adjustment of the Series B Conversion Price will be made
when Convertible Securities are actually issued upon the exercise of such
Options or when Common Stock is actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities. No further
adjustment of the Series E Conversion Price will be made when Convertible
Securities are actually issued upon the exercise of such Options or when Common
Stock is actually issued upon the exercise of such Options or the conversion or
exchange of such Convertible Securities. No further adjustment of the Series F
Conversion Price will be made when Convertible Securities are actually issued
upon the exercise of such Options or when Common Stock is actually issued upon
the exercise of such Options or the conversion or exchange of such Convertible
Securities. No further adjustment of the Series H Conversion Price will be made
when Convertible Securities are actually issued upon the exercise of such
Options or when Common Stock is actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities.

          (ii) If the Corporation in any manner issues or sells any Convertible
Securities and the price per share for which Common Stock is issuable upon such
conversion or exchange is less than the Series A Conversion Price in effect
immediately prior to the time of such issue or sale, then the maximum number of
shares of Common Stock issuable upon conversion or exchange of such Convertible
Securities will be deemed to be outstanding and to have been issued and sold by
the Corporation for such price per share.  If the Corporation in any manner
issues or sells any Convertible Securities and the price per share for which
Common Stock is issuable upon such conversion or exchange is less than the
Series B Conversion Price in effect immediately prior to the time of such issue
or sale, then the maximum number of shares of Common Stock issuable upon
conversion or exchange of such 

                                       20
<PAGE>
 
Convertible Securities will be deemed to be outstanding and to have been issued
and sold by the Corporation for such price per share. If the Corporation in any
manner issues or sells any Convertible Securities and the price per share for
which Common Stock is issuable upon such conversion or exchange is less than the
Series E Conversion Price in effect immediately prior to the time of such issue
or sale, then the maximum number of shares of Common Stock issuable upon
conversion or exchange of such Convertible Securities will be deemed to be
outstanding and to have been issued and sold by the Corporation for such price
per share. If the Corporation in any manner issues or sells any Convertible
Securities and the price per share for which Common Stock is issuable upon such
conversion or exchange is less than the Series F Conversion Price in effect
immediately prior to the time of such issue or sale, then the maximum number of
shares of Common Stock issuable upon conversion or exchange of such Convertible
Securities will be deemed to be outstanding and to have been issued and sold by
the Corporation for such price per share. If the Corporation in any manner
issues or sells any Convertible Securities and the price per share for which
Common Stock is issuable upon such conversion or exchange is less than the
Series H Conversion Price in effect immediately prior to the time of such issue
or sale, then the maximum number of shares of Common Stock issuable upon
conversion or exchange of such Convertible Securities will be deemed to be
outstanding and to have been issued and sold by the Corporation for such price
per share. For the purposes of this paragraph, the "price per share for which
Common Stock is issuable" will be determined by dividing (a) the total amount
received or receivable by the Corporation as consideration for the issue or sale
of such Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Corporation upon the conversion or
exchange thereof, by (b) the total maximum number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities. No
further adjustment of the Series A Conversion Price will be made when Common
Stock is actually issued upon the conversion or exchange of such Convertible
Securities, and if any such issue or sale of such Convertible Securities is made
upon exercise of any Options for which adjustments of the Series A Conversion
Price had been or are to be made pursuant to other provisions of this part 5, no
further adjustment of the Series A Conversion Price will be made by reason of
such issue or sale. No further adjustment of the Series B Conversion Price will
be made when Common Stock is actually issued upon the conversion or exchange of
such Convertible Securities, and if any such issue or sale of such Convertible
Securities is made upon exercise of any Options for which adjustments of the
Series B Conversion Price had been or are to be made pursuant to other
provisions of this part 5, no further adjustment of the Series B Conversion
Price will be made by reason of such issue or sale. No further adjustment of the
Series E Conversion Price will be made when Common Stock is actually issued upon
the conversion or exchange of such Convertible Securities, and if any such issue
or sale of such Convertible Securities is made upon exercise of any Options for
which adjustments of the Series E Conversion Price had been or are to be made
pursuant to other provisions of this part 5, no further adjustment of the Series
E Conversion Price will be made by reason of such issue or sale. No further
adjustment of the Series F Conversion Price will be made when Common Stock is
actually issued upon the conversion or exchange of such Convertible Securities,
and if any such issue or sale of such Convertible Securities is made upon
exercise of any Options for which adjustments of the Series F Conversion Price
had been or are to be made pursuant to other provisions of this part 5, no
further adjustment of the Series F Conversion Price will be made by reason of
such issue or sale. No further adjustment of the Series H Conversion Price will
be made when Common Stock is actually issued upon the conversion or exchange of
such Convertible Securities, and if any such issue or sale of such Convertible
Securities is made upon exercise of any Options for which adjustments of the
Series H Conversion Price had been or are to be made pursuant to other
provisions of this part 5, no further adjustment of the Series H Conversion
Price will be made by reason of such issue or sale.

          (iii)  If the purchase price provided for in any Options, the
additional consideration, if any, payable upon the conversion or exchange of any
Convertible Securities, or the rate at which any Convertible Securities are
convertible into or exchangeable for Common Stock changes at any time, the
Series A Conversion Price in effect at the time of such change will be
readjusted to the Series A Conversion Price which would have been in effect at
such time had such Options or Convertible Securities still outstanding provided
for such changed purchase price, additional consideration or changed conversion
rate, as the case may be, at the time initially granted, issued or sold.  If the
purchase price provided for in any Options, the additional consideration, if
any, payable upon the conversion or exchange of any Convertible Securities, or
the rate at which any Convertible Securities are convertible into or
exchangeable for Common Stock changes at any time, the Series B Conversion Price
in effect at the time of such change will be readjusted to the Series B
Conversion Price which would have been in effect at such time had such Options
or Convertible Securities still outstanding provided for such changed purchase
price, 

                                       21
<PAGE>
 
additional consideration or changed conversion rate, as the case may be, at the
time initially granted, issued or sold. If the purchase price provided for in
any Options, the additional consideration, if any, payable upon the conversion
or exchange of any Convertible Securities, or the rate at which any Convertible
Securities are convertible into or exchangeable for Common Stock changes at any
time, the Series E Conversion Price in effect at the time of such change will be
readjusted to the Series E Conversion Price which would have been in effect at
such time had such Options or Convertible Securities still outstanding provided
for such changed purchase price, additional consideration or changed conversion
rate, as the case may be, at the time initially granted, issued or sold. If the
purchase price provided for in any Options, the additional consideration, if
any, payable upon the conversion or exchange of any Convertible Securities, or
the rate at which any Convertible Securities are convertible into or
exchangeable for Common Stock changes at any time, the Series F Conversion Price
in effect at the time of such change will be readjusted to the Series F
Conversion Price which would have been in effect at such time had such Options
or Convertible Securities still outstanding provided for such changed purchase
price, additional consideration or changed conversion rate, as the case may be,
at the time initially granted, issued or sold. If the purchase price provided
for in any Options, the additional consideration, if any, payable upon the
conversion or exchange of any Convertible Securities, or the rate at which any
Convertible Securities are convertible into or exchangeable for Common Stock
changes at any time, the Series H Conversion Price in effect at the time of such
change will be readjusted to the Series H Conversion Price which would have been
in effect at such time had such Options or Convertible Securities still
outstanding provided for such changed purchase price, additional consideration
or changed conversion rate, as the case may be, at the time initially granted,
issued or sold.

          (iv) Upon the expiration of any Option or the termination of any right
to convert or exchange any Convertible Security without the exercise of any such
Option or right, the Series A Conversion Price then in effect hereunder will be
adjusted to the Series A Conversion Price which would have been in effect at the
time of such expiration or termination had such Option or Convertible Security,
to the extent outstanding immediately prior to such expiration or termination,
never been issued.  Upon the expiration of any Option or the termination of any
right to convert or exchange any Convertible Security without the exercise of
any such Option or right, the Series B Conversion Price then in effect hereunder
will be adjusted to the Series B Conversion Price which would have been in
effect at the time of such expiration or termination had such Option or
Convertible Security, to the extent outstanding immediately prior to such
expiration or termination, 

                                       22
<PAGE>
 
never been issued. Upon the expiration of any Option or the termination of any
right to convert or exchange any Convertible Security without the exercise of
any such Option or right, the Series E Conversion Price then in effect hereunder
will be adjusted to the Series E Conversion Price which would have been in
effect at the time of such expiration or termination had such Option or
Convertible Security, to the extent outstanding immediately prior to such
expiration or termination, never been issued. Upon the expiration of any Option
or the termination of any right to convert or exchange any Convertible Security
without the exercise of any such Option or right, the Series F Conversion Price

Option or Convertible Security, to the extent outstanding immediately prior to
such expiration or termination, never been issued. Upon the expiration of any
Option or the termination of any right to convert or exchange any Convertible
Security without the exercise of any such Option or right, the Series H
Conversion Price then in effect hereunder will be adjusted to the Series H
Conversion Price which would have been in effect at the time of such expiration
or termination had such Option or Convertible Security, to the extent
outstanding immediately prior to such expiration or termination, never been
issued.

          (v)    If any Common Stock, Option or Convertible Security is issued
or sold or deemed to have been issued or sold for cash, the consideration
received therefor will be deemed to be the net amount received by the
Corporation therefor. In case any Common Stock, Options or Convertible
Securities are issued or sold for a consideration other than cash, the amount of
the consideration other than cash received by the Corporation will be the Fair
Market Value thereof as of the date of receipt. If any Common Stock, Option or
Convertible Security is issued in connection with any merger in which the
Corporation is the surviving corporation, the amount of consideration therefor
will be deemed to be the Fair Market Value of such portion of the net assets and
business of the non-surviving corporation as is attributable to such Common
Stock, Options or Convertible Securities, as the case may be.

          (vi)   In case any Option is issued in connection with the issue or
sale of other securities of the Corporation, together comprising one integrated
transaction in which no specific consideration is allocated to such Option by
the parties thereto, the Option will be deemed to have been issued for a
consideration of $0.01.

          (vii)  The number of shares of Common Stock outstanding at any given
time does not include shares owned or held by or for the account of the
Corporation or any Subsidiary, and the disposition of any shares so owned or
held will be considered an issue or sale of Common Stock.

          (viii) If the Corporation takes a record of the holders of Common
Stock for the purpose of entitling them (a) to receive a dividend or other
distribution payable in Common Stock, Options or Convertible Securities or (b)
to subscribe for or purchase Common Stock, Options or Convertible Securities,
then such record date will be deemed to be the date of the issue or sale of the
shares of Common Stock deemed to have been issued or sold upon the declaration
of such dividend or upon the making of such other distribution or the date of
the granting of such right of subscription or purchase, as the case may be.

     5D.  Subdivision or Combination of Common Stock.  If the Corporation at
any time subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its outstanding shares of Common Stock into a
greater number of shares, the Series A Conversion Price, Series B Conversion
Price, Series C Conversion Price, Series D Conversion Price, Series E Conversion
Price, Series F Conversion Price, Series G Conversion Price and Series H
Conversion Price in effect immediately prior to such subdivision will be
proportionately reduced, and if the 

                                       23
<PAGE>
 
Corporation at any time combines (by reverse stock split or otherwise) one or

shares, the Series A Conversion Price, Series B Conversion Price, Series C
Conversion Price, Series D Conversion Price, Series E Conversion Price, Series F
Conversion Price, Series G Conversion Price and Series H Conversion Price in
effect immediately prior to such combination will be proportionately increased.

     5E.  Certain Events.  If any event occurs of the type contemplated by the
provisions of this part 5 but not expressly provided for by such provisions
(excluding for purposes of the Series C Conversion Price, the Series D

subparts 5B and 5C), then the Board of Directors will make an appropriate
adjustment in the Series A Conversion Price, Series B Conversion Price, Series C
Conversion Price, Series D Conversion Price, Series E Conversion Price, Series F
Conversion Price, Series G Conversion Price and Series H Conversion Price so as
to protect the rights of the holders of shares of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock,
Series E Preferred Stock, Series F Preferred Stock, Series G Preferred Stock and
Series H Preferred Stock; provided that no such adjustment will increase the
Series A Conversion Price, Series B Conversion Price, Series C Conversion Price,
Series D Conversion Price, Series E Conversion Price, Series F Conversion Price,
Series G Conversion Price or Series H Conversion Price as otherwise determined
pursuant to this part 5 or decrease the number of shares of Common Stock
issuable upon conversion of each share of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
Preferred Stock, Series F Preferred Stock, Series G Preferred Stock and Series H
Preferred Stock.

stockholders, only such business shall be conducted as shall be properly before
the meeting.  To be properly before a meeting, business must be (a) specified in
the notice of meeting (or any supplement thereto) given by or at the direction
of the Board of Directors, (b) otherwise properly brought before the meeting by
or at the direction of the Board of Directors, or (c) otherwise properly brought

thereof in writing to the Secretary.  To be timely, a stockholder's notice must
be delivered to or mailed and received at the principal place of business of the
corporation not less than thirty (30) days nor more than sixty (60) days prior
to the meeting; provided, however, that in the event that less than forty (40)
days notice or prior public disclosure of the date of the meeting is given or
made to stockholders, notice by the stockholder to be timely must be 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.  A stockholder's written notice to the Secretary shall set forth as to
each matter the stockholder proposes to bring before the meeting (a) a brief
description of the business desired to be brought before the meeting and the
reasons for conducting such business at the meeting, (b) the name and address as
they appear on the corporation's books of the stockholder proposing such
business, (c) the class and number of shares of the corporation which are
beneficially owned by such stockholder, and (d) any material interest of such
stockholder in such business.  Notwithstanding anything in these Bylaws to the
contrary, no business shall be conducted at a meeting unless properly brought

13 of Article II.  The chairman of the meeting shall, if the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting in accordance with the provisions of this Section 13 of
Article II and if it shall be so determined, the chairman of the meeting shall
so declare this to the meeting and such business not properly brought before the
meeting shall not be transacted.

          Section 14.  Action Without a Meeting.  Unless otherwise provided in
                       ------------------------

or special meeting of stockholders of the corporation, or any action which 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, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take 

                                       4

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.

become disqualified, disabled, or otherwise removed.  Directors need not be

directors may be filled by a majority of the directors then in office, though
less than a quorum, or by a sole remaining director.  The directors so chosen
shall serve for the remainder of the term of the vacated directorships being
filled and until their successors are duly elected and shall qualify, unless
sooner displaced.  If there are no directors in office, then an election of
directors may be held in the manner provided by statute.

          Section 4.  Location of Meetings.  The Board of Directors of the

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.

permitted by Section 145 of the Delaware General Corporation Law, as that
Section may be amended and supplemented from time to time, indemnify any
director, officer, employee or agent of the corporation, against expenses
(including attorneys' fees), judgments, fines, amounts paid in settlement and/or
other matters referred to in or covered by that Section, by reason of the fact
that he 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.

          Section 2.  Advancing Expenses.  Expenses incurred by a director of
                      ------------------                                     
the corporation in defending a civil or criminal action, suit or proceeding by
reason of the fact that he 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) shall be paid by the corporation in advance
of the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
corporation as authorized by relevant provisions of the Delaware General
Corporation Law; provided, however, the corporation shall not be required to
advance such expenses to a director (i) who commences any action, suit or
proceeding as a plaintiff unless such advance is specifically approved by a
majority of the Board of Directors, or (ii) who is a party to an action, suit or
proceeding brought by the corporation and approved by a majority of the Board of
Directors which alleges willful misappropriation of corporate assets by such
director, disclosure of confidential information in violation of such director's
fiduciary or contractual obligations to the corporation, or any other willful
and deliberate breach in bad faith of such director's duty to the corporation or
its stockholders.

          Section 3.  Liability Offset.  The corporation's obligation to provide
                      ----------------                                          
indemnification under this Article VIII shall be offset to the extent the
indemnified party is indemnified by any other source including, but not limited
to, any applicable insurance coverage under a policy maintained by the
corporation, the indemnified party or any other person.

          Section 4.  Continuing Obligation.  The provisions of this Article
                      ---------------------                                 
VIII shall be deemed to be a contract between the corporation and each director
of the corporation who serves in such capacity at any time while this bylaw is
in effect, and any repeal or modification thereof shall not affect any rights or
obligations then existing with respect to any state of facts then or theretofore
existing or 

                                       13
<PAGE>
 
any action, suit or proceeding theretofore or thereafter brought based in whole
or in part upon any such state of facts.

          Section 5.  Nonexclusive.  The indemnification and advancement of
                      ------------                                         
expenses provided for in this Article VIII shall (i) not be deemed exclusive of
any other rights to which those indemnified may be entitled under any by-law,
agreement or vote of stockholders or disinterested directors or otherwise, both
as to action in their official capacities and as to action in another capacity
while holding such office, (ii) continue as to a person who has ceased to be a
director and (iii) inure to the benefit of the heirs, executors and
administrators of such a person.

          Section 6.  Other Persons.  In addition to the indemnification rights
                      -------------                                            
of directors, officers, employees, or agents of the corporation, the Board of
Directors in its discretion shall have the power on behalf of the corporation to
indemnify any other person made a party to any action, suit or proceeding who
the corporation may indemnify under Section 145 of the Delaware General
Corporation Law.

          Section 7.  Definitions.  The phrases and terms set forth in this
                      -----------                                          
Article VIII shall be given the same meaning as the identical terms and phrases
are given in Section 145 of the Delaware General Corporation Law, as that
Section may be amended and supplemented from time to time.

                             VIGNETTE CORPORATION
                            A DELAWARE CORPORATION


                                   ARTICLE I

                                    OFFICES

          SECTION 1.  The registered office shall be in the City of
Wilmington, County of New Castle, State of Delaware.

          SECTION 2.  The corporation may also have offices at such other
places both within and without the State of Delaware as the Board of Directors
may from time to time determine or the business of the corporation may require.

                                  ARTICLE II

                           MEETINGS OF STOCKHOLDERS

          SECTION 1.  All meetings of the stockholders for the election of
directors shall be held at such time and place, within or without the State of
Delaware, as may be fixed from time to time by the Board of Directors, and
stated in the notice of the meeting.  Meetings of stockholders for any other
purpose may be held at such time and place, within or without the State of
Delaware, as shall be stated in the notice of the meeting or in a duly executed
waiver of notice thereof.

          SECTION 2.

          (a) Annual meetings of stockholders, commencing with the year 1999,
shall be held at such date and time as shall be designated from time to time by
the Board of Directors and stated in the notice of the meeting, at which they
shall elect by a plurality vote a board of directors, and transact such other
business as may properly be brought before the meeting.

          (b) Nominations of persons for election to the Board of Directors of
the Corporation and the proposal of business to be considered by the
stockholders may be made at an annual meeting of stockholders (i) pursuant to
the Corporation's notice of meeting, (ii) by or at the direction of the Board of
Directors or (iii) by any stockholder of the Corporation who was a stockholder
of record at the time of giving of the notice provided for in this by-law, who
is entitled to vote at the meeting and who complied with the notice procedures
set forth in this by-law.

          (c) For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (iii) of paragraph (b) of
this by-law, the stockholder must have given timely notice thereof in writing to
the Secretary of the Corporation and any such 
<PAGE>
 
business must otherwise be a proper matter for stockholder action under Delaware
law. To be timely, a stockholder's notice shall be delivered to the Secretary at
the principal executive offices of the Corporation not less than 60 days nor
more than 90 days prior to the first anniversary of the preceding year's annual
meeting; provided, however, that in the event that the date of the annual
meeting is advanced by more than 30 days or delayed by more than 60 days from
such anniversary date, notice by the stockholder to be timely must be so
delivered not earlier than the 90/th/ day prior to such annual meeting and not
later than the close of business on the later of the 60/th/ day prior to such
annual meeting or the 10/th/ day following the day on which public announcement
of the date of such meeting is first made. Such stockholder's notice shall set
forth (i) as to each person whom the stockholder proposes to nominate for
election or reelection as a director all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
directors, or is otherwise required, in each case pursuant to Regulation 14A
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")
(including such person's written consent to being named in the proxy statement
as a nominee and to serving as a director if elected); (ii) as to any other
business that the stockholder proposes to bring before the meeting, a brief
description of the business desired to be brought before the meeting, the
reasons for conducting such business at the meeting and any material interest in
such business of such stockholder and the beneficial owner, if any, on whose
behalf the proposal is made; and (iii) as to the stockholder giving the notice
and the beneficial owner, if any, on whose behalf the nomination or proposal is
made (a) the name and address of such stockholder, as they appear on the
Corporation's books, and of such beneficial owner and (b) the class and number
of shares of the Corporation which are owned beneficially and of record by such
stockholder and such beneficial owner.

          (d) Notwithstanding anything in the second sentence of paragraph (c)
of this by-law to the contrary, in the event that the number of directors to be
elected to the Board of Directors of the Corporation is increased and there is
no public announcement naming all of the nominees for director or specifying the
size of the increased Board of Directors made by the Corporation at least 70
days prior to the first anniversary of the preceding year's annual meeting, a
stockholder's notice required by this by-law shall also be considered timely,
but only with respect to nominees for any new positions created by such
increase, if it shall be delivered to the Secretary at the principal executive
offices of the Corporation not later than the close of business on the 10/th/
day following the day on which such public announcement is first made by the
Corporation.

          (e) Only such persons who are nominated in accordance with the
procedures set forth in these By-laws shall be eligible to serve as directors
and only such business shall be conducted at an annual meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in these By-laws.  The chairman of the meeting shall have the power
and duty to determine whether a nomination or any business proposed to be
brought before the meeting was made in accordance with the procedures set forth
in these By-laws.  The chairman of the meeting shall have the power and duty to
determine whether a nomination or any business proposed to be brought before the
meeting was made in accordance with the procedures set forth in these By-laws,
and, if any proposed nomination or business is not in compliance with these By-
laws, to declare that such defective proposed business or nomination shall be
disregarded.

<PAGE>
 
          (f) For purposes of these By-laws, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or a comparable national news service or in a document publicly filed by
the Corporation with the Securities and Exchange Commission pursuant to Section
13, 14 or 15(d) of the Exchange Act.

          (g) Notwithstanding the foregoing provisions of this by-law, a
stockholder shall also comply with all applicable requirements of the Exchange
Act and the rules and regulations thereunder with respect to the matters set
forth in this by-law.  Nothing in this by-law shall be deemed to affect any
rights of stockholders to request inclusion of proposals in the Corporation's
proxy statement pursuant to Rule 14a-8 under the Exchange Act.

          SECTION 3.  Written notice of the annual meeting stating the place,
date and hour of the meeting shall be given to each stockholder entitled to vote
at such meeting not fewer than ten (10) nor more than sixty (60) days before the
date of the meeting.

          SECTION 4.  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 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.

          SECTION 5.  Special meetings of the stockholders, for any purpose
or purposes, unless otherwise prescribed by statute or by the certificate of
incorporation, may be called at any time by the Board of Directors pursuant to a
resolution approved by a majority of the whole Board of Directors.  Such
resolution shall state the purpose or purposes of the proposed meeting.

          SECTION 6.  Written notice of a special meeting stating the place,
date and hour of the meeting and the purpose or purposes for which the meeting
is called, shall be given not fewer than ten (10) nor more than sixty (60) days
before the date of the meeting, to each stockholder entitled to vote at such
meeting.

          SECTION 7.  Business transacted at any special meeting of
stockholders shall be limited to the purposes stated in the notice.

          SECTION 8.  The holders of a majority 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 shall not be present or
represented at any meeting of the stockholders, the stockholders entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or 

                                       3
<PAGE>
 
represented. At such adjourned meeting at which a quorum shall be present or
represented any business may be transacted that might have been transacted at
the meeting as originally notified. 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.

          SECTION 9.  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 statutes or of
the certificate of incorporation, a different vote is required, in which case
such express provision shall govern and control the decision of such question.

          SECTION 10. Unless otherwise provided in the certificate of
incorporation, each stockholder shall at every meeting of the stockholders be
entitled to one vote in person or by proxy for each share of the capital stock
having voting power held by such stockholder, but no proxy shall be voted on
after three (3) years from its date, unless the proxy provides for a longer
period.



                                  ARTICLE III

                                   DIRECTORS

          SECTION 1.  The number of directors shall be fixed from time to
time exclusively by the Board of Directors pursuant to a resolution adopted by a
vote of 75% of the total number of authorized directors (whether or not there
exist any vacancies in previously authorized directorships at the time any such
resolution is presented to the Board for adoption).  Directors shall be divided
into three classes, as nearly equal in number as reasonably possible, with the
term of office of the first class to expire at the 1999 annual meeting of
stockholders, the term of office of the second class to expire at the 2000
annual meeting of stockholders and the term of office of the third class to
expire at the 2001 annual meeting of stockholders.  At each annual meeting of
stockholders following such initial classification and election, directors
elected to succeed those directors whose terms expire shall be elected for a
term of office to expire at the third succeeding annual meeting of stockholders
after their election.  All directors shall hold office until the expiration of
term for which elected, and until their respective successors are elected and
qualified, except in the case of the death, resignation or removal of any
director.  Directors need not be stockholders.

          SECTION 2.  Vacancies and newly created directorships resulting from
any increase in the authorized number of directors may be filled by a majority
of the directors then in office, though less than a quorum, or by a sole
remaining director, and not by stockholders, and the directors so chosen shall
hold office until the next annual election and until their successors are duly
elected and shall qualify, unless sooner displaced. If there are no directors in
office, then an election of directors may be held in the manner provided by
statute.

                                       4
<PAGE>
 
          SECTION 3.  The business of the corporation shall be managed by or
under the direction of its board of directors, which may exercise all such
powers of the corporation and do all such lawful acts and things as are not by
statute or by the certificate of incorporation or by these bylaws directed or
required to be exercised or done by the stockholders.

                      MEETINGS OF THE BOARD OF DIRECTORS

          SECTION 4.  The Board of Directors of the corporation may hold
meetings, both regular and special, either within or without the State of
Delaware.

          SECTION 5.  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 and no notice of such meeting shall be
necessary to the newly elected directors in order legally to constitute the
meeting, provided a quorum shall be present.  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.

          SECTION 6.  Regular meetings of the Board of Directors may be held
without notice at such time and at such place as shall from time to time be
determined by the board.

          SECTION 7.  Special meetings of the Board of Directors may be
called by the president on ten (10) days' notice to each director by mail or
forty-eight (48) hours notice to each director either personally or by
telephone, telegram or facsimile; special meetings shall be called by the
president or secretary in like manner and on like notice on the written request
of two (2) directors unless the board consists of only one director, in which
case special meetings shall be called by the president or secretary in like
manner and on like notice on the written request of the sole director.

          SECTION 8.  At all meetings of the board a majority of the directors
shall constitute a quorum for the transaction of business and the act of a
majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the certificate of incorporation. If a
quorum shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

          SECTION 9.  Unless otherwise restricted by the certificate of
incorporation of these bylaws, any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting, if all members of the board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the board or committee.

                                       5
<PAGE>
 
          SECTION 10. Unless otherwise restricted by the certificate of
incorporation or these bylaws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

                            COMMITTEES OF DIRECTORS

          SECTION 11. The Board of Directors may, by resolution passed by a
majority of the whole board, designate one (1) or more committees, each
committee to consist of one (1) or more of the directors of the corporation.
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.

          In the absence of disqualification of a member of a committee, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not he or she or they constitute a quorum, may unanimously
appoint another member of the Board of Directors to act at the meeting in the
place of any such absent or disqualified member.

          Any such committee, to the extent provided in the resolution of the
Board of Directors, shall have and may exercise all the powers and authority of
the Board of Directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers that may require it; but no such committee shall have the power or
authority in reference to amending the certificate of incorporation, adopting an
agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the corporation's property and
assets, recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the bylaws of the corporation; and,
unless the resolution or the certificate of incorporation expressly so provide,
no such committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock.  Such committee or committees shall have such
name or names as may be determined from time to time by resolution adopted by
the Board of Directors.

          SECTION 12. Each committee shall keep regular minutes of its meetings
and report the same to the Board of Directors when required.

                           COMPENSATION OF DIRECTORS

          SECTION 13. Unless otherwise restricted by the certificate of
incorporation or these bylaws, the Board of Directors shall have the authority
to fix the compensation of directors.  The directors may be paid their expenses,
if any, of attendance at each meeting of the Board of Directors and may be paid
a fixed sum for attendance at each meeting of the Board of Directors or a stated
salary as director.  No such payment shall preclude any director from serving
the corporation in any other capacity and receiving compensation therefor.
Members of special or standing committees may be allowed like compensation for
attending committee meetings.

                                    NOTICES

          SECTION 1.  Whenever, under the provisions of the statutes or of
the certificate of incorporation or of these bylaws, notice is required to be
given to any director or stockholder, it shall not be construed to mean personal
notice, but such notice may be given in writing, by mail, addressed to such
director or stockholder, at his address as it appears on the records of the
corporation, with postage thereon prepaid, and such notice shall be deemed to be
given at the time when the same shall be deposited in the United States mail.
Notice to directors may also be given by telegram, telephone or facsimile.

          SECTION 2.  Whenever any notice is required to be given under the
provisions of the statutes or of the certificate of incorporation or of these
bylaws, a waiver thereof in writing, signed by the person or persons entitled to
said notice, whether before or after the time stated therein, shall be deemed
equivalent thereto.

incorporation or these bylaws otherwise provide.

          SECTION 2.  The Board of Directors at its first meeting after each
annual meeting of stockholders shall choose a president, a treasurer, and a

                                INDEMNIFICATION

          SECTION 6.  The corporation shall, to the fullest extent authorized
under the laws of the State of Delaware, as those laws may be amended and
supplemented from time to time, indemnify any director made, or threatened to be
made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director of the
corporation or a predecessor corporation or, at the corporation's request, a
director or officer of another corporation, provided, however, that the
corporation shall indemnify any such agent in connection with a proceeding
initiated by such agent only if such proceeding was authorized by the Board of
Directors of the corporation.  The indemnification provided for in this Section
6 shall: (i) not be deemed exclusive of any other rights to which those
indemnified may be entitled under any bylaw, agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in their official
capacities and as to action in another capacity while holding such office, (ii)
continue as to a person who has ceased to be a director, and (iii) inure to the
benefit of the heirs, executors and administrators of such a person.  The
corporation's obligation to provide indemnification under this Section 6 shall
be offset to the extent of any other source of indemnification or any otherwise
applicable insurance coverage under a policy maintained by the corporation or
any other person.

          Expenses incurred by a director or officer of the corporation in
defending a civil or criminal action, suit or proceeding by reason of the fact
that he or she is or was a director or officer of the corporation (or was
serving at the corporation's request as a director or officer of another
corporation) shall be paid by the corporation in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of such director or officer to repay such amount if it shall
ultimately be determined that such director or officer is not entitled to be
indemnified by the corporation as authorized by relevant sections of the General
Corporation Law of Delaware.  Notwithstanding the foregoing, the corporation
shall not be required to advance such expenses to an agent who is a party to an
action, suit or proceeding 

                                       12
<PAGE>
 
brought by the corporation and approved by a majority of the Board of Directors
of the corporation that alleges willful misappropriation of corporate assets by
such agent, disclosure of confidential information in violation of such agent's
fiduciary or contractual obligations to the corporation or any other willful and
deliberate breach in bad faith of such agent's duty to the corporation or its
stockholders.

          The foregoing provisions of this Section 6 shall be deemed to be a
contract between the corporation and each director or officer who serves in such
capacity at any time while this bylaw is in effect, and any repeal or
modification thereof shall not affect any rights or obligations then existing
with respect to any state of facts then or theretofore existing or any action,
suit or proceeding theretofore or thereafter brought based in whole or in part
upon any such state of facts.

          The Board of Directors in its discretion shall have power on behalf of
the corporation to indemnify any person, other than a director or officer, made
a party to any action, suit or proceeding by reason of the fact that such
person, their testator or intestate, is or was an officer or employee of the
corporation.

          To assure indemnification under this Section 6 of all directors,
officers and employees who are determined by the corporation or otherwise to be
or to have been "fiduciaries" of any employee benefit plan of the corporation
that may exist from time to time, Section 145 of the General Corporation Law of
Delaware shall, for the purposes of this Section 6, be interpreted as follows:
an "other enterprise" shall be deemed to include such an employee benefit plan,
including without limitation, any plan of the corporation that is governed by
the Act of Congress entitled "Employee Retirement Income Security Act of 1974,"
as amended from time to time; the corporation shall be deemed to have requested
a person to serve an employee benefit plan where the performance by such person
of his duties to the corporation also imposes duties on, or otherwise involves
services by, such person to the plan or participants or beneficiaries of the
plan; excise taxes assessed on a person with respect to an employee benefit plan
pursuant to such Act of Congress shall be deemed "fines."

                                 ARTICLE VIII

                                  AMENDMENTS

          SECTION 1.  These bylaws may be altered, amended or repealed or new
bylaws may be adopted by stockholders holding at least seventy-five percent
(75%) of the Company's outstanding capital stock ("Amending Stockholders") or by
the Board of Directors, when such power is conferred upon the Board of Directors
by the certificate of incorporation at any regular meeting of the stockholders
or of the Board of Directors or by the Amending Stockholders at any special
meeting of the stockholders or by the Board of Directors at any special meeting
of the Board of Directors if notice of such alteration, amendment, repeal or
adoption of new bylaws be contained in the notice of such special meeting.  If
the power to adopt, amend or repeal bylaws is conferred upon the Board of
Directors by the certificate or incorporation it shall not divest or limit the
power of the stockholders to adopt, amend or repeal bylaws.

Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series E
Preferred Stock, Series F Preferred Stock and Series H Preferred Stock and,

the shares of Common Stock (as such terms are defined in paragraph 4K) issued or
issuable upon the conversion of such shares of Series A Preferred Stock, Series
B Preferred Stock, Series C Preferred Stock, Series E Preferred Stock, Series F
Preferred Stock and Series H Preferred Stock are referred to in this Agreement

election of directors of the Company, they shall vote all shares of capital
stock of the Company owned or controlled by them, including all Shares, to elect
a Board of Directors comprising six directors (unless reduced to a fewer number
of directors as described below) designated as follows:

               (i)         two shall be directors designated by the holders of a
majority of the Common Stock held by the Common Stockholders;

               (ii)        one shall be designated by Austin Ventures, one shall
be designated by Sigma and one shall be designated by CNET (as such terms are
defined in Exhibit A hereto); and

               (iii)       one shall be designated by the holders of a majority
of the Common Stock held by the Common Stockholders and the Shares, voting
together as a single class.

          In the event shares of Series A Preferred Stock or Series B Preferred

V.B of the Company's Fourth Amended and Restated Certificate of Incorporation,
as hereafter amended or restated), Austin Ventures, Sigma and CNET shall cause
the directors designated by them in (ii) above to resign, and the number of
directors constituting the entire Board of Directors shall be reduced by three
directors.

          Each director designated in (i) above is referred to as a "Common
Stockholder Director."  Each director designated in (ii) above is referred to as
a "Purchaser Director."  The director designated in (iii) above is referred to

Purchaser Director designated by Austin Ventures shall be John D. Thornton, the

Director position to be designated by CNET shall be vacant and the Common
Stockholder Directors shall be Ross B. Garber and Neil Webber.

establish and maintain a compensation committee comprised of two of the
Purchaser Directors and a director designated by the chief executive officer of
the Company. The compensation committee of the Board of Directors shall be

and benefits of officers and key employees of the Company and its subsidiaries,
and will administer the Approved Plans (as defined in paragraph 4K) and any
other stock option, incentive or compensation plans or arrangements.

               C.   Vacancies; Removal. In the event of any vacancy in the Board
of Directors, each of the Purchasers and the Common Stockholders agrees to vote
all Shares and shares of Common Stock owned or controlled by them and to
otherwise use their best efforts to fill such vacancy so that the Board of
Directors of the Company will include directors designated as provided in
paragraph 1A. Each of the Purchasers and the Common Stockholders agrees to vote
all Shares and shares of Common Stock owned or controlled by them for the
removal of a director whenever (but only whenever) there shall be presented to
the Board of Directors the written direction that such director be removed,
signed by the holders of a majority of the Shares, in the case of a Purchaser
Director, or by the holders of a majority of the Common Stock held by the Common
Stockholders, in the case of a Common Stockholder Director, or by the holders of
a majority of the Common Stock held by the Common Stockholders and the Shares,
in the case of the At Large Director. Each of the parties agrees to use its best
efforts to cause designees to be elected to the Board of Directors as provided
in paragraph 1A.

               D.   Meetings; Quorum. The Company agrees to hold regularly
scheduled meetings of the Board of Directors as determined by a majority of the
Board of Directors. The Company will give each Purchaser that is entitled
hereunder to either appoint a Purchaser Director or designate an observer
pursuant to paragraph 1E below (so long as such Purchaser holds any Shares)
written notice at least three days (24 hours, in the case of a telephone
meeting) in advance of all meetings of the Board of Directors and all meetings
of committees of the Board of Directors. If the Purchaser Director designated by
a Purchaser is not able to attend a Board of Directors meeting or a meeting of a
committee on which he serves, such Purchaser may designate any one person to
attend as an observer. The Company shall furnish each such Purchaser with a copy
of the minutes and other records of all meetings and other actions taken by the
Board of Directors and its committees and all written material given to
directors in connection with such meeting at the same time such materials and
information are given to the directors. If the Company proposes to take any
action by written consent in lieu of a meeting of its Board of Directors or any
committee thereof, the Company shall give written notice thereof to each
Purchaser Director prior to the effective date of such consent describing in
reasonable detail the nature and the substance of such action.

          2.   Provisions Relating to Restricted Stock.

               A.   General Restrictions on Transfer of Capital Stock;
Dividends.

                    (i)    For purposes of this Agreement, "Restricted Stock" is
Common Stock now owned or subsequently acquired by any Common Stockholder or a
transferee of a Common Stockholder in a Permitted Transfer (as defined below).
During the term of this Agreement, none of the shares of Restricted Stock may be
sold, assigned, transferred, pledged, encumbered or otherwise disposed of (a
"transfer") except in a "Permitted Transfer" or a transfer that complies with
the provisions of paragraphs 2B and 2C.

                    (ii)   Any attempted transfer of shares of Restricted Stock
other than in accordance with this Agreement shall be null and void and the
Company shall refuse to recognize any such transfer and shall not reflect on its
records any change in record ownership of shares of Restricted Stock pursuant to
any such transfer.

                    (iii)  The following transfers of Restricted Stock (each
such transfer being a "Permitted Transfer", and each transferee in such transfer
being a "Permitted Transferee") may be made free of the restrictions and
requirements of paragraphs 2B and 2C

                                       4
<PAGE>
 
hereof: (a) an individual holder of Restricted Stock may transfer any or all of
the shares of Restricted Stock owned by him to his spouse or children, or to
trusts established for the benefit of his spouse or children, provided that the
transferee grants to the transferor an irrevocable proxy coupled with an
interest to vote all of the shares of Restricted Stock so transferred and agrees
to be bound by the provisions of this Agreement, including, without limitation,
paragraphs 2B and 2C; (b) provided that the transferee agrees to be bound by the
provisions of this Agreement, a partnership, corporation or trust holding
Restricted Stock may transfer any shares of Restricted Stock owned by such
holder (1) to its Affiliates (as defined under the Securities Act of 1933), (2)
to its general or limited partners, shareholders or beneficiaries, or (3) to an
entity owned by or organized for the benefit of the general or limited partners,
shareholders, officers, directors, employees, Affiliates or beneficiaries of
such holder, as applicable, (c) a holder of Restricted Stock may pledge any
shares of Restricted Stock owned by such holder to secure the repayment of any
bona fide indebtedness owing by such holder, the Company or any Subsidiary to a
financial institution, provided that such holder retains the power to vote the
shares of Restricted Stock so pledged until such time as the pledgee shall have
realized upon the pledge and that the provisions of this Agreement, including,
without limitation, paragraphs 2B and 2C, shall be applicable to the shares of
Restricted Stock so pledged and (iv) a holder of Restricted Stock may sell
Restricted Stock to the Company pursuant to an agreement under which the Company
has the option to repurchase such Restricted Stock upon the occurrence of
certain events, including the termination of employment by or service to the
Company or any subsidiary of the Company.

               B.   Right of First Refusal.

                    (i)    Subject to paragraph 2B(v), whenever and as often as
any Common Stockholder or a Permitted Transferee of a Common Stockholder desires
to sell any shares of Restricted Stock pursuant to a bona fide written offer to
purchase such shares, such Common Stockholder (the "Selling Holder" for purposes
of this paragraph 2B) shall give written notice (the "Notice," for purposes of
this paragraph 2B) to the Company, to each Founder who on the date of such
Notice is a full-time employee of the Company and each holder of Shares (each an
"Offeree," for the purposes of this paragraph 2B) to such effect, enclosing a
copy of such offer and specifying the number of shares of Restricted Stock which
the Selling Holder desires to sell, the name of the person or persons to whom
the Selling Holder desires to make such sale and the consideration per share of
Common Stock which has been offered in connection with such offer.

                    (ii)   Upon receipt of the Notice, the Offerees shall
initially have the first right and option to purchase the shares proposed to be
sold for cash at the same purchase price and on the same terms as specified in
the Notice, pro rata according to their respective holdings of Common Stock and
Shares, exercisable for seven days after receipt of the Notice. Failure of any
Offeree to respond to the Notice within the seven-day period shall be deemed to
constitute a notification to the Selling Holder of such Offeree's decision not
to exercise the first right and option to purchase shares of Restricted Stock
under this paragraph 2B. If any Offeree fails to exercise its first right and
option, the Selling Holder shall give written notice to each of the other
Offerees who has elected to purchase his or her or its pro rata share of the
shares of Restricted Stock proposed to be transferred, and each such Offeree
shall have the right, exercisable for a period of three days from the date of
receipt of such Notice, to purchase the remaining shares of Restricted Stock,
pro rata according to the Common Stock and Shares held

                                       5
<PAGE>
 
by all such electing Offerees or in such other proportions as they may agree
upon. In the event such consideration includes non-cash consideration, the
dollar value of such non-cash consideration shall be its Fair Market Value (as
defined in paragraph 4K). The Offerees may exercise the right and option
provided above by giving written notice of exercise to the Selling Holder within
such seven-day period, specifying the date (not later than three days from the
date of expiration of all applicable first right and options to purchase shares
under this paragraph) upon which payment of the purchase price for the shares
purchased pursuant to this paragraph shall be made. The Selling Holder shall
deliver to the Offeree(s) at the Company's principal office, at least one day
prior to the payment date, wire transfer instructions, and on the payment date
specified in such notice, the certificate or certificates representing such
shares, properly endorsed for transfer, against payment of the purchase price
therefor by the Offeree(s) in immediately available funds.

                    (iii)   In the event that all of the shares of Restricted
Stock proposed to be transferred are not purchased by the Offerees, the Company
shall have the right and option to purchase the balance of the shares proposed
to be sold for cash at the purchase price per share specified in the Notice,
exercisable for seven days after expiration of the option period set forth in
paragraph 2B(ii). The Company may assign its right and option to purchase such
Restricted Stock to any other person. Failure of the Company to respond to such
Notice within such seven-day period shall be deemed to constitute a notification
to the Selling Holder of the Company's decision not to exercise the first right
and option to purchase such shares under this paragraph. The Company may
exercise its right and option to purchase such Restricted Stock by giving
written notice of exercise to the Selling Holder within such seven-day period,
specifying the date (not later than three days from the date of such notice)
upon which payment of the purchase price for the shares shall be made. The
Selling Holder shall deliver to the Company's principal office, on or before the
payment date specified in such notice, the certificate or certificates
representing the shares being purchased by the Company, properly endorsed for
transfer, against payment of the purchase price therefor by the Company in
immediately available funds.  

                    (iv)   If all the shares of Restricted Stock proposed to be
transferred are not purchased by the Offerees and the Company in accordance with
this paragraph 2B, the Selling Holder shall not be required to sell any of the
shares of Restricted Stock proposed to be transferred to the Offerees or to the
Company, and during the 60-day period commencing on the expiration of the rights
and options provided for in this paragraph, may sell all (but not less than all)
of such shares to the transferee named in the Notice for a consideration equal
to or greater than the consideration specified in the Notice, free of the
restrictions contained in paragraphs 2B and 2C (but subject to the other terms
and conditions of this Agreement).

                    (v)    Whenever and as often as any Common Stockholder shall
receive a bona fide offer to purchase any shares of Restricted Stock from a
prospective purchaser which the Selling Holder wishes to accept, each Purchaser
shall have the right, at such Purchaser's option, either to exercise its rights
under paragraph 2B(ii) or to participate in the sale to the prospective
purchaser pursuant to this paragraph 2B(v). The Selling Holder will use
reasonable best efforts to arrange for the sale to the prospective purchaser of
the number of each

                                       6
<PAGE>
 
such Purchaser's shares of Common Stock, Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series E Preferred Stock, Series F
Preferred Stock and Series H Preferred Stock which bears the same proportion to
the total number of shares of Common Stock, Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series E Preferred Stock, Series F
Preferred Stock and Series H Preferred Stock owned by such Purchaser as the
number of shares of Restricted Stock being sold by the Selling Holder bears to
the total number of shares of Restricted Stock owned by the Selling Holder, as
applicable, at the purchase price per share and on the terms and conditions
specified in the Notice. For purposes of this paragraph 2B(v), a Purchaser may
elect to sell Common Stock at the purchase price per share specified for the
Common Stock in the Notice, and may elect to sell Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock, Series E Preferred Stock,
Series F Preferred Stock or Series H Preferred Stock at the purchase price per
share of Common Stock specified for the Common Stock in the Notice multiplied by
the number of shares of Common Stock into which a share of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock, Series E Preferred
Stock, Series F Preferred Stock or Series H Preferred Stock, as applicable, is
then convertible. If the prospective purchaser will not purchase all the shares
which the Selling Holder and the Purchasers wish to sell pursuant to this
paragraph 2B(v), the number of shares which the Selling Holder and Purchasers
shall be entitled to sell to such prospective purchaser shall be a number of
shares equal to the number of shares which the prospective purchaser desires to
purchase times a fraction, the numerator of which is the number of shares of
Restricted Stock beneficially owned by the Selling Holder or the number of
shares of Common Stock, Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series E Preferred Stock, Series F Preferred Stock and
Series H Preferred Stock beneficially owned by each selling Purchaser, as
appropriate, and the denominator of which is the aggregate number of shares of
Restricted Stock, Common Stock, Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, Series E Preferred Stock, Series F Preferred
Stock and Series H Preferred Stock beneficially owned by the Selling Holder and
all such selling Purchasers. An Offeree may exercise his or her or its right
under this paragraph by written notice given within seven days after receipt of
the Notice.

               C.   Voting of Restricted Stock.

                    (i)    In the event that a Founder is no longer employed by
the Company, such holder shall vote all his shares in accordance with the other
Founder, as long as such other Founder is employed by the Company.

                    (ii)   In the event that neither Founder is employed by the
Company, all the Founders shall vote their shares as directed by the chief
executive officer of the Company on the date of such vote.

          3.   Preemptive Rights.

               A.   Pre-Qualified Public Offering. If, prior to a Qualified
Public Offering (as defined in paragraph 4K), the Company shall issue any Equity
Securities (as defined in paragraph 4K) consisting of Common Stock or other
Equity Securities, each Founder who on the date of the notice of such proposed
issuance referred to below is a full-time employee of the Company and each
holder of shares of Series A Preferred Stock, Series B Preferred Stock,

                                       7
<PAGE>
 
Series C Preferred Stock, Series E Preferred Stock, Series F Preferred Stock and
Series H Preferred Stock shall be entitled to purchase the portion of such
Common Stock or Equity Securities to be issued necessary in order that the
aggregate shares of Common Stock and Shares held by such holder constitute the
same percentage of all Common Stock (assuming the conversion, exercise or
exchange of all Equity Securities) after the issuance of such Common Stock or
Equity Securities as before the issuance thereof; provided, however, that such
preemptive right shall not apply to (a) issuances of Common Stock or Equity
Securities pursuant to an Approved Plan (as defined in paragraph 4K), (b)
issuances of Common Stock or Equity Securities pursuant to warrants granted in
connection with a capital equipment financing, (c) issuances of Common Stock or
Equity Securities upon the conversion, exercise or exchange of Equity Securities
to which the preemptive right was applicable, (d) issuances of Common Stock or
Equity Securities in connection with an exercise of the preemptive rights
granted hereunder, (e) issuances of Shares pursuant to the Stock Purchase
Agreement, dated as of February 5, 1996, among the Company, Austin Ventures,
Sigma and the Founders, (f) issuances of Shares pursuant to the Stock Purchase
Agreement, dated as of July 19, 1996, among the Company and CNET, (g) issuances
of Shares pursuant to the Stock Purchase Agreement, dated as of June 6, 1997,
among the Company, Attractor (as such term is defined in Exhibit A hereto),

Purchase Agreement, dated as of July 17, 1997, among the Company, Adobe, Austin
Ventures, Charles River, Sigma, the Founders and certain other parties, (i)
issuances of Shares pursuant to the Purchase Agreement, dated as of April 22,
1998 among the Company, Adobe, Amerindo, Attractor, Austin Ventures, Charles
River, GSCP, H&Q and Sigma (as such terms are defined in Exhibit A hereto), (j)
issuances of Shares pursuant to the Purchase Agreement (k) issuances of Series D
Warrants from time to time by the Company or issuances of Equity Securities upon
exercise thereof, or (l) issuances of Common Stock upon conversion of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock, Series F Preferred Stock and Series H
Preferred Stock. The price of securities which each holder becomes entitled to
purchase by reason hereof shall be the same price at which such securities are
proposed to be offered to others.

               B.   First Qualified Public Offering. In the Company's first
Qualified Public Offering, each Purchaser of Series F Preferred Stock and Series
H Preferred Stock shall be entitled to purchase a portion (the "Proportionate
Share") of such Equity Securities to be issued in such offering. Subject to the
limitations of the following sentence, for Purchasers of Series F Preferred
Stock other than Attractor, the Proportionate Share shall be that portion of the
shares to be issued in such offering, necessary in order that (I) the sum of (A)
the Proportionate Share and (B) the number of shares of Common Stock issuable
upon conversion of the Series F Preferred Stock held by such Purchaser divided
by (II) the number of shares of Common Stock outstanding immediately after such
offering (assuming the full conversion, exercise or exchange of all Equity
Securities) equals (x) the number of shares of Common Stock issuable upon
conversion of the Series F Preferred Stock held by such Purchaser divided by (y)
the number of shares of Common Stock outstanding immediately before such
offering (assuming the full conversion, exercise or exchange of all Equity
Securities); for Attractor, the Proportionate Share shall be that portion of the
shares to be issued in such offering, necessary in order that (I) the sum of (A)
the Proportionate Share and (B) the number of shares of Common Stock issuable
upon conversion of the Series E Preferred Stock and Series F Preferred Stock
held by Attractor divided by (II) the

                                       8
<PAGE>
 
number of shares of Common Stock outstanding immediately after such offering
(assuming the full conversion, exercise or exchange of all Equity Securities)
equals (x) the number of shares of Common Stock issuable upon conversion of the
Series E Preferred Stock and Series F Preferred Stock held by Attractor divided
by (y) the number of shares of Common Stock outstanding immediately before such
offering (assuming the full conversion, exercise or exchange of all Equity
Securities); for Purchasers of Series H Preferred Stock, the Proportionate Share
shall be that portion of the shares to be issued in such offering, necessary in
order that (I) the sum of (A) the Proportionate Share and (B) the number of
shares of Common Stock issuable upon conversion of the Series H Preferred Stock
held by such Purchaser divided by (II) the number of shares of Common Stock
outstanding immediately after such offering (assuming the full conversion,
exercise or exchange of all Equity Securities) equals (x) the number of shares
of Common Stock issuable upon conversion of the Series H Preferred Stock held by
such Purchaser divided by (y) the number of shares of Common Stock outstanding
immediately before such offering (assuming the full conversion, exercise or
exchange of all Equity Securities). Notwithstanding the foregoing sentence, (i)
the Proportionate Shares of Purchasers of Series F Preferred Stock, in the
aggregate, as Purchasers of Series F Preferred Stock, may not exceed 10% of such
offering, (ii) the Proportionate Shares of Purchasers of Series H Preferred
Stock, in the aggregate, as Purchasers of Series H Preferred Stock, may not
exceed the lesser of (x) the percentage of such offering sold by selling
stockholders of the Company and (y) 2.5% of such offering, (iii) except as
provided below, Amerindo shall not be entitled to purchase a Proportionate Share
hereunder with respect to its Series H Preferred Stock, and, with respect to
this paragraph 3B only, the number of shares of Series H Preferred Stock
outstanding immediately before the offering shall not include the Series H
Preferred Stock held by Amerindo, (iv) in the event that any holder of Series H
Preferred Stock does not purchase its full Proportionate Share, the
Proportionate Share of each purchasing holder of Series H Preferred Stock shall
increase by the product of (A) the portion of shares not purchased, and (B) (x)
the number of shares of Series H Preferred Stock held by such purchasing holder
of Series H Preferred Stock divided by (y) the number of shares of Series H
Preferred Stock outstanding immediately before the offering less the number of
shares of Series H Preferred Stock of the holders not purchasing their
Proportionate Share, (v) in the event that all holders of Series H Preferred
Stock other than Amerindo do not purchase the full number of shares available
for purchase by the holders of Series H Purchasers under (ii) above, Amerindo
shall be entitled to purchase the number of Equity Securities equal to the
difference between (x) the aggregate amount of shares purchased by all other
holders of Series H Preferred Stock, in the aggregate, as Purchasers of Series H
Preferred Stock and (y) the maximum number of shares available for purchase by
the holders of Series H Purchasers under (ii) above, (vi) any holder of Series H
Preferred Stock may assign the right to purchase its Proportionate Share to an
Affiliate of such Series H Purchaser or to an entity managed by Partech
International, and (vii) the Proportionate Shares may be cut back to the extent
deemed necessary to the success of such offering by the managing underwriter
thereof in its reasonable opinion confirmed in writing to the Purchasers not
less than two weeks prior to the effective date of the registration statement
covering such securities; provided, however, in the event of an oversubscription
of the Proportionate Shares, such shares shall be allocated first so that each
of Attractor, Amerindo and the Series H Purchasers receives its full
Proportionate Share (and in the event that such shares are insufficient for each
of Attractor, Amerindo and the Series H Purchasers to receive their full
Proportionate Share, then each of Attractor's, Amerindo's and the Series H
Purchasers' Proportionate Share

                                       9
<PAGE>
 
shall be cut back pro rata, based upon their full Proportionate Share) and
second, among the remaining Series F Purchasers pro rata based upon their
respective holdings of Series F Preferred Stock. The price of securities which
each such Purchaser of Series F Preferred Stock and Series H Preferred Stock
becomes entitled to purchase by reason hereof shall be the same price at which
such securities are initially offered to the public.

               C.   Procedures. A holder may exercise its right under paragraph
3A to purchase Equity Securities by paying the purchase price therefor at the
principal office of the Company within ten days after receipt of notice from the
Company (which notice by the Company shall be given at least 15 days before the
issuance of the Equity Securities) stating the number or amount of Equity
Securities it intends to issue and the price and characteristics thereof. In the
first Qualified Public Offering, the Company shall give notice to the holders of
Series E Preferred Stock, Series F Preferred Stock and Series H Preferred Stock
at least 15 days prior to the filing of the registration statement relating to
such offering stating the number or amount of Equity Securities the Company
intends to issue and the anticipated offering price and characteristics thereof.
A Purchaser may exercise his or its right under paragraph 3B to purchase Equity
Securities by giving notice to the Company of his or its commitment to purchase
within ten days after receipt of the Company's notice and paying the purchase
price therefor on the date and at the place of the closing of such offering. The
holder shall pay such purchase price in cash or by check; provided, however,
that if the Company is indebted to such holder, the holder shall be entitled, at
the holder's sole option, to credit against the purchase price all or any
portion of the Company's indebtedness to such holder which is then due (accrued
but unpaid dividends on the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series E Preferred Stock, Series F Preferred Stock and
Series H Preferred Stock shall not be deemed to be indebtedness for purposes of
such credit). A holder's contractual preemptive rights hereunder shall be deemed
to be exercised immediately prior to the close of business on the day of payment
of the purchase price in accordance with the foregoing provisions, and at such
time such holder shall be treated for all purposes as the record holder of the
Equity Securities, as the case may be. As promptly as practicable (and in any
event within ten days) on or after the purchase date, the Company shall issue
and deliver at its principal office a certificate or certificates for the number
of full shares of Common Stock or the number of full shares or amount, whichever
is applicable, of Equity Securities together with cash for any fraction of a
share or portion of an Equity Security at the purchase price to which the holder
is entitled hereunder.

          4.   General Provisions.

               A.   Legends on Certificates. During the term of this Agreement,
each certificate representing shares of Common Stock or Shares will bear a
legend in substantially the following form:

     TRANSFER, PLEDGE OR OTHER DISPOSITION AND VOTING THEREOF ARE SUBJECT TO

Company and the holders of 80% or more of the Shares then outstanding and the
holders of at least a majority of the Common Stock outstanding, or (c) the
acquisition by a single purchaser of all of the issued and outstanding shares of
the Common Stock and the Shares. Notwithstanding the foregoing sentence, this
Agreement shall survive a Qualified Public Offering to the extent necessary to
satisfy paragraph 3B. hereof.

                    (ii)   This Agreement may be amended by the written
agreement of the Company and the holders of 80% or more of the Shares then
outstanding.

affirmative vote of the holders of at least 95% of the Series E Preferred Stock
and/or Series F Preferred Stock, respectively, then outstanding, voting as a
separate class.

                    (iv)   Notwithstanding the foregoing paragraphs 4B(i) and
(ii), this Agreement may not be amended to materially and adversely affect the
holders of Series H Preferred Stock without the affirmative vote of the holders
of at least 80% of the Series H Preferred Stock then outstanding, voting as a
separate class.

Registrable Series E Stock then outstanding), and (b) the intended method of
distribution of such shares. Within ten days after the date of its receipt of
such request, the Company will give written notice of such requested
registration to all other Holders of Registrable Stock and, subject to paragraph
2A(vi), will include in such registration all shares of Registrable Stock which
Holders of Registrable Stock request the Company to include in such registration
by written notice given to the Company within 15 days after the date of sending
of the Company's notice.

                  (iii)  At any time and from time to time after January 31,
2001, the holders of at least 66-2/3% of the Registrable Series F Stock then
outstanding may request registration under the Securities Act of the offering of
all or any part of the Registrable Stock held by such Holders (each, a "Demand
Registration"), subject to the terms and conditions of this Agreement. Any
request (a "Registration Request") for a Demand Registration shall specify (a)
the approximate number of shares of Registrable Series F Stock requested to be
registered (but not less than a majority of the total number of shares of
Registrable Series F Stock then outstanding), and (b) the intended method of
distribution of such shares. Within ten days after

                                       3
<PAGE>
 
the date of its receipt of such request, the Company will give written notice of
such requested registration to all other Holders of Registrable Stock and,
subject to paragraph 2A(vi), will include in such registration all shares of
Registrable Stock which Holders of Registrable Stock request the Company to
include in such registration by written notice given to the Company within 15
days after the date of sending of the Company's notice.

                  (iv)   At any time and from time to time after January 31,
2001, the holders of at least 66-2/3% of the Registrable Series H Stock then
outstanding may request registration under the Securities Act of the offering of
all or any part of the Registrable Stock held by such Holders (each, a "Demand
Registration"), subject to the terms and conditions of this Agreement. Any
request (a "Registration Request") for a Demand Registration shall specify (a)
the approximate number of shares of Registrable Series H Stock requested to be
registered (but not less than a majority of the total number of shares of
Registrable Series H Stock then outstanding), and (b) the intended method of
distribution of such shares. Within ten days after the date of its receipt of
such request, the Company will give written notice of such requested
registration to all other Holders of Registrable Stock and, subject to paragraph
2A(vi), will include in such registration all shares of Registrable Stock which
Holders of Registrable Stock request the Company to include in such registration
by written notice given to the Company within 15 days after the date of sending
of the Company's notice.

                  (v)    Subject to paragraph 4, the Holders of Registrable
Series A and Series B Stock will be entitled to request up to two Demand
Registrations at any time and from time to time and the Holders of Registrable
Series E Stock, Registrable Series F Stock and Registrable Series H Stock will
be entitled to request up to two Demand Registrations at any time and from time
to time.

                  (vi)   In connection with a Demand Registration with respect
to Registrable Series A and Series B Stock, a registration will not count as one
of the Demand Registrations paid for by the Company (as provided in paragraph 4)
unless the holders of Registrable Series A and Series B Stock are able to
register the offering of and sell at least 50% of the shares of Registrable
Series A and Series B Stock requested to be included in such registration. In
connection with a Demand Registration with respect to Registrable Series E
Stock, a registration will not count as one of the Demand Registrations paid for
by the Company (as provided in paragraph 4) unless the holders of Registrable
Series E Stock are able to register the offering of and sell at least 50% of the
shares of Registrable Series E Stock requested to be included in such
registration. In connection with a Demand Registration with respect to
Registrable Series F Stock, a registration will not count as one of the Demand
Registrations paid for by the Company (as provided in paragraph 4) unless the
holders of Registrable Series F Stock are able to register the offering of and
sell at least 50% of the shares of Registrable Series F Stock requested to be
included in such registration. In connection with a Demand Registration with
respect to Registrable Series H Stock, a registration will not count as one of
the Demand Registrations paid for by the Company (as provided in paragraph 4)
unless the holders of Registrable Series H Stock are able to register the
offering of and sell at least 50% of the shares of Registrable Series H Stock
requested to be included in such registration.

                  (vii)  The Company will not include in any Demand Registration
the offering of any securities other than shares of Registrable Stock and
securities to be

                                       4
<PAGE>
 
registered for offering and sale on behalf of the Company without the prior
written consent of the Holders of a majority of the shares of Registrable Series
A and Series B Stock, Registrable Series E Stock, Registrable Series F Stock or
Registrable Series H Stock, as the case may be, included in such registration.
If the managing underwriter(s) of any such offering advise the Company in
writing that in their opinion the number of shares of Registrable Stock and, if
permitted hereunder, other securities in such offering, exceeds the number of
shares of Registrable Stock and other securities, if any, which can be sold in
an orderly manner in such offering within a price range acceptable to the
Holders of a majority of the shares of Registrable Series A and Series B Stock,
Registrable Series E Stock, Registrable Series F Stock or Registrable Series H
Stock, as the case may be, initially requesting registration, the Company will
include in such registration, prior to the inclusion of any securities which are
not shares of Registrable Series A and Series B Stock, Registrable Series E
Stock, Registrable Series F Stock or Registrable Series H Stock, as the case may
be, subject to a Registration Request the number of shares requested to be
included which in the opinion of such underwriters can be sold in an orderly
manner within the price range of such offering, in the following order of
priority: (i) first, pro rata among the Holders of Registrable Series A and
Series B Stock, Registrable Series E Stock, Registrable Series F Stock or
Registrable Series H Stock, as the case may be, making the Registration Request
on the basis of the number of shares that such Holders have requested be
included in the registration, (ii) second, to the Company, (iii) third, pro rata
among the Holders of other Registrable Stock requesting to be included in such
registration on the basis of the number of shares that such holders have
requested be included in the registration, and (iv) fourth, pro rata among the
holders of the other securities, if any, requested to be included in such
registration on the basis of the number of shares that such holders have
requested be included in the registration.

        B.  Selection of Managing Underwriter(s).  The holders of a majority of
the then outstanding shares of Registrable Series A and Series B Stock,
Registrable Series E Stock, Registrable Series F Stock or Registrable Series H
Stock, as the case may be, requesting a registration will have the right to
select one or more underwriters to manage any offering which is the subject of a
Demand Registration, subject to the Company's approval which will not be
unreasonably withheld.

        C.  Registrations on Forms S-2 and S-3.  Following its initial public
offering of securities under the Securities Act, the Company shall use its
reasonable best efforts to qualify for registration on Forms S-2 or S-3 or any
comparable or successor form or forms. After the Company has qualified for the
use of Form S-2 or S-3, in addition to the rights contained in paragraph 2A, the
Holders of at least 25% of the Registrable Series A and Series B Stock shall
have the right at any time and from time to time to request up to two
registrations on Form S-2 and an unlimited number of registrations on Form S-3.
After the Company has qualified for the use of Form S-2 or S-3, in addition to
the rights contained in paragraph 2A, the Holders of at least 25% of the
Registrable Series E Stock shall have the right at any time and from time to
time to request up to two registrations on Form S-2 and an unlimited number of
registrations on Form S-3. After the Company has qualified for the use of Form
S-2 or S-3, in addition to the rights contained in

                                       5
<PAGE>
 
paragraph 2A, the Holders of at least 25% of the Registrable Series F Stock
shall have the right at any time and from time to time to request up to two
registrations on Form S-2 and an unlimited number of registrations on Form S-3.
After the Company has qualified for the use of Form S-2 or S-3, in addition to
the rights contained in paragraph 2A, the Holders of at least 25% of the
Registrable Series H Stock shall have the right at any time and from time to
time to request up to two registrations on Form S-2 and an unlimited number of
registrations on Form S-3. After the Company has qualified for the use of Form 
S-3, (i) the holders of at least 25% of the Registrable Series C Stock shall
have the right at any time and from time to time to request an unlimited number
of registrations on Form S-3 and (iii) the holders of at least 25% of the
Registrable Founders Stock shall have the right at any time and from time to
time to request an unlimited number of registrations on Form S-3. Such requests
shall be in writing and shall state the number of shares of Registrable Stock
proposed to be disposed of and the intended method of distribution of such
shares by such Holder or Holders.

        D.  Right to Defer Registration.  The Company shall not be obligated to
effect any registration on behalf of any Holder or transferee thereof within 180
days after the effective date of a previous registration in which such Holder or
transferee participated. The Company may postpone for up to 180 days the filing
or the effectiveness of a registration statement for a Demand Registration set
forth above if (i) the Company determines that such registration might have an
adverse effect on any proposal or plan by the Company to engage in any
acquisition of assets (other than in the ordinary course) or any merger,
consolidation, tender offer or similar transaction or (ii) any other material,
nonpublic development or transaction is pending; provided that the Company may
not postpone the filing or effectiveness of a registration statement pursuant to
this sentence more frequently than once during any period of 12 consecutive
months.

    3.  Piggyback Registrations.

        A.  Right to Piggyback.  If the Company proposes to register any
offering of its securities under the Securities Act (other than pursuant to a
Demand Registration or registration solely in connection with an employee
benefit or stock ownership plan) and the registration form to be used may be
used for the registration of Registrable Stock (a "Piggyback Registration"), the
Company will give prompt written notice to all Holders of Registrable Stock of
its intention to effect such a registration (each a "Piggyback Notice"). Subject
to subparagraph 3B below, the Company will include in such registration all
shares of Registrable Stock which Holders of Registrable Stock request the
Company to include in such registration by written notice given to the Company
within 15 days after the date of sending of the Company's notice.

        B.  Priority on Primary Registrations.  If a Piggyback Registration
relates to an underwritten public offering of equity securities by the Company
and the managing underwriters of such offering advise the Company in writing
that in their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in an orderly manner in such
offering within a price range acceptable to the Company, the Company will
include in such registration (i) first, the securities proposed to be sold by
the Company, (ii) second, the Registrable Series A and Series B Stock,
Registrable Series E Stock, Registrable Series F Stock and Registrable Series H
Stock requested to be included in such registration, pro rata among the Holders
of such Registrable Series A and Series B Stock, Registrable Series E Stock,
Registrable Series F Stock and Registrable Series H Stock on the basis of the
number of shares owned by each such Holder, (iii) third, the Registrable
Founders Stock and Registrable Series C Stock requested to be included in such
registration, pro rata

                                       6
<PAGE>
 
among the Holders of such Registrable Founders Stock and Registrable Series C
Stock on the basis of the number of shares owned by each such Holder, and (iv)
fourth, other securities requested to be included in such registration.

        C.  Priority on Secondary Registrations.  If a Piggyback Registration
relates to an underwritten public offering of equity securities by holders of
the Company's securities and the managing underwriters of such offering advise
the Company in writing that in their opinion the number of securities requested
to be included in such registration exceeds the number which can be sold in an
orderly manner in such offering within a price range acceptable to the holders
initially requesting such registration, the Company will include in such
registration (i) first, the securities requested to be included therein by the
holders requesting such registration, (ii) second, the Registrable Series A and
Series B Stock, Registrable Series E Stock, Registrable Series F Stock and
Registrable Series H Stock requested to be included in such registration, pro
rata among the Holders of such Registrable Series A and Series B Stock,
Registrable Series E Stock, Registrable Series F and Registrable Series H Stock
on the basis of the number of shares owned by each such Holder, and (iii) third,
the Registrable Founders Stock and Registrable Series C Stock requested to be
included in such registration, pro rata among the Holders of such Registrable
Founders Stock and Registrable Series C Stock on the basis of the number of
shares owned by each such Holder.

    4.  Registration Procedures.  Whenever the Holders of Registrable Stock have
requested that any Registrable Stock be registered pursuant to this Agreement,
the Company will use its best efforts to effect the registration and the sale of
such Registrable Stock in accordance with the intended method of distribution
thereof and will as expeditiously as possible:

            (i)    prepare and file with the Commission a registration statement
with respect to such Registrable Stock and use its best efforts to cause such
registration statement to become effective, provided, that before filing a
registration statement or prospectus or any amendments or supplements thereto,
the Company will furnish to the counsel selected by the Holders of a majority of
the Registrable Stock covered by such registration statement copies of all such
documents proposed to be filed, which documents will be subject to the review of
such counsel;

            (ii)   prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
a period of up to six months, and comply with the provisions of the Securities
Act with respect to the disposition of all securities covered by such
registration statement during such period in accordance with the intended
methods of distribution by the sellers thereof set forth in such registration
statement;

            (iii)  furnish to each seller of Registrable Stock included in such
registration such number of copies of such registration statement, each
amendment and supplement thereto, the prospectus included in such registration
statement (including each preliminary prospectus) and such other documents as
such seller may reasonably request in order to facilitate the disposition of
such Registrable Stock by such seller;

                                       7
<PAGE>
 
            (iv)   use its best efforts to register or qualify such Registrable
Stock under such other securities or blue sky laws of such jurisdictions as any
seller reasonably requests and do any and all other acts and things which may be
reasonably necessary or advisable to enable such seller to consummate the
disposition in such jurisdictions of the Registrable Stock owned by such seller,
provided, that the Company will not be required (i) to qualify generally to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this subparagraph, (ii) to subject itself to taxation in any such
jurisdiction or (iii) to consent to general service of process in any such
jurisdiction;

            (v)    notify each seller of such Registrable Stock, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading and, at the request of any such seller, the Company will prepare
a supplement or amendment to such prospectus so that, as thereafter delivered to
the purchasers of such Registrable Stock, such prospectus will not contain an
untrue statement of a material fact or omit to state any fact necessary to make
the statements therein, in light of the circumstances under which such
statements are made, not misleading;

            (vi)   cause all such Registrable Stock to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and to be qualified for trading on each system on which similar
securities issued by the Company are from time to time qualified;

            (vii)  provide a transfer agent and registrar for all such
Registrable Stock not later than the effective date of such registration
statement and thereafter maintain such a transfer agent and registrar;

            (viii) enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the shares of Registrable Stock being sold or the underwriters, if
any, reasonably request in order to expedite or facilitate the disposition of
such Registrable Stock;

            (ix)   make available for inspection by any underwriter
participating in any disposition pursuant to such registration statement and any
attorney, accountant or other agent retained by any such underwriter, all
financial and other records, pertinent corporate documents and properties of the
Company, and cause the Company's officers, directors, employees and independent
accountants to supply all information reasonably requested by any such
underwriter, attorney, accountant or agent in connection with such registration
statement;

            (x)    otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission, and make available to its security
holders, as soon as reasonably practicable, an earnings statement covering the
period of at least 12 months beginning with the first day of the Company's first
full calendar quarter after the effective date of the registration statement,
which earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder;

                                       8
<PAGE>
 
            (xi)   permit any Holder of Registrable Stock which might be deemed,
in the sole and exclusive judgment of such Holder, to be an underwriter or a
controlling person of the Company, to participate in the preparation of such
registration or comparable statement and to require the insertion therein of
material, furnished to the Company in writing, which in the reasonable judgment
of such Holder and its counsel should be included; and

            (xii)  in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Registrable Stock included in such registration statement for sale in any
jurisdiction, the Company will use its reasonable best efforts promptly to
obtain the withdrawal of such order.

If any such registration or comparable statement refers to any Holder by name or
otherwise as the holder of any securities of the Company and if, in such
Holder's sole and exclusive judgment, such Holder is or might be deemed to be a
controlling person of the Company, such Holder shall have the right to require
(a) the inclusion in such registration statement of language, in form and
substance reasonably satisfactory to such Holder, to the effect that the holding
of such securities by such Holder is not to be construed as a recommendation by
such Holder of the investment quality of the Company's securities covered
thereby and that such holding does not imply that such Holder will assist in
meeting any future financial requirements of the Company, or (b) in the event
that such reference to such Holder by name or otherwise is not required by the
Securities Act or any similar federal statute then in force, the deletion of the
reference to such Holder; provided, that with respect to this clause (b) such
Holder shall furnish to the Company an opinion of counsel to such effect, which
opinion and counsel shall be reasonably satisfactory to the Company.

    5.  Registration Expenses.

        A.  Definitions.  The term "Registration Expenses" means all expenses
incident to the Company's performance of or compliance with this Agreement,
including without limitation all registration and filing fees, fees and expenses
of compliance with securities or blue sky laws, printing expenses, messenger and
delivery expenses, and fees and expenses of counsel for the Company and all
independent certified public accountants, underwriters (excluding discounts and
commissions, which shall be paid by the selling shareholders out of the proceeds
of the applicable offering) and other Persons retained by the Company.

        B.  Payment.  The Company shall pay the Registration Expenses (other
than fees and disbursements of counsel for the Holders, except as set forth in
the following sentence) in connection with two Demand Registrations requested by
Holders of Registrable Series A and B Stock, two Demand Registrations requested
by Holders of Registrable Series E Stock, two Demand Registrations requested by
Holders of Registrable Series F Stock, two Demand Registrations requested by
Holders of Registrable Series H Stock, up to two registrations on Form S-2 and
any and all registrations on Form S-3 pursuant to paragraph 2C and any and all
Piggyback Registrations. In connection with each Demand Registration and each
Piggyback Registration, the Company will reimburse the Holders of Registrable
Stock covered by such registration for the reasonable fees and disbursements of
one counsel chosen by the Holders of a majority of the Registrable Stock
initially requesting such registration.

                                       9
<PAGE>
 
    6.  Indemnification.

        A.  Indemnification by the Company.  The Company agrees to indemnify, to
the extent permitted by law, each Holder, its officers and directors and each
Person who controls such Holder (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities and expenses caused by any
untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as the same are caused by or contained in any
information furnished in writing to the Company by such Holder expressly for use
therein or by such Holder's failure to deliver a copy of the registration
statement or prospectus or any amendments or supplements thereto after the
Company has furnished such Holder with a sufficient number of copies of the
same. In connection with an underwritten offering, the Company will indemnify
such underwriters, their officers and directors and each Person who controls
such underwriters (within the meaning of the Securities Act) to the same extent
as provided above with respect to the indemnification of the Holders.

        B.  Indemnification by Holders.  In connection with any registration
statement in which a Holder is participating, each such Holder will furnish to
the Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, will indemnify the Company, its
directors and officers and each Person who controls the Company (within the
meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses resulting from any untrue or alleged untrue statement of material
fact contained in the registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading (but only to the extent that such
untrue statement or omission is contained in any information or affidavit so
furnished in writing by such Holder) and any failure by each such Holder to
deliver a copy of the registration statement or prospectus or any amendments or
supplements thereto after the Company has furnished such Holder with a
sufficient number of copies of the same; provided, that the obligation to
indemnify will be individual to each Holder and will be limited to the net
amount of proceeds received by such Holder from the sale of Registrable Stock
pursuant to such registration statement.

        C.  Notice: Defense of Claims.  Any Person entitled to indemnification
hereunder will (i) give prompt written notice to the indemnifying party of any
claim with respect to which it seeks indemnification and (ii) unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is assumed,
the indemnifying party will not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a

                                       10
<PAGE>
 
conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim.

        D.  Survival; Contribution.  The indemnification provided for under this
Agreement will remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party or any officer, director or
controlling Person of such indemnified party and will survive the transfer of
securities.  The Company also agrees to make such provisions as are reasonably
requested by any indemnified party for contribution to such party in the event
the Company's indemnification is unavailable for any reason.

    7.  Participation in Underwritten Registrations.  No Person may participate
in any registration hereunder which is underwritten unless such Person (i)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements; (ii) completes and executes all questionnaires,
powers of attorney, indemnities, standstill or holdback agreements, underwriting
agreements and other documents required under the terms of such underwriting
arrangements, provided, that no Holder of Registrable Stock included in any
underwritten registration shall be required to make any representations or
warranties to the Company or the underwriters other than representations and
warranties regarding such Holder and such Holder's intended method of
distribution. In any case, each Holder, if requested by the managing underwriter
or underwriters, agrees not to sell Registrable Stock or other securities held
by such Holder in any transaction other than pursuant to such underwriting for
such period (not to exceed 180 days) as determined at the discretion of the
Board of Directors of the Company, provided, that no holder of Registrable Stock
shall be required to enter into such an agreement unless each other Holder of
Registrable Stock, each director and executive officer of the Company and each
other holder of at least five percent of the Common Stock then outstanding
enters into a substantially identical agreement relating to such underwriting.

    8.  Miscellaneous.

        A.  No Inconsistent Agreements.  The Company will not hereafter enter
into any agreement with respect to its securities which is inconsistent with or
violates the rights granted to the Holders of Registrable Stock in this
Agreement.

        B.  Adjustments Affecting Registrable Stock.  The Company will not take
any action, or permit any change to occur, with respect to its securities for
the purpose of materially and adversely affecting the ability of the Holders of
Registrable Stock to include such Registrable Stock in a registration undertaken
pursuant to this Agreement or materially and adversely affecting the
marketability of such Registrable Stock in any such registration (including,
without limitation, effecting a stock split or a combination of shares),
provided, that this subparagraph 8B shall not apply to actions or changes with
respect to the Company's business, balance sheet, earnings or revenues where the
effect of such actions or changes on the Registrable Stock is merely incidental.

        C.  Notices.  All notices, requests, consents, and other communications
under this Agreement shall be in writing and shall be delivered personally or by
facsimile transmission or by overnight delivery service or mailed by first class
certified or registered U.S.

                           INDEMNIFICATION AGREEMENT
                           -------------------------


     This Indemnification Agreement ("Agreement") is made as of      by and 
between Vignette Corporation, a Delaware corporation (the "Company"), and
("Director").

                                   Recitals:
                                   -------- 

     The Company and Director recognize the increasing difficulty in obtaining
directors' and officers' liability insurance, the significant increases in the
cost of such insurance and the general reductions in the coverage of such
insurance;

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

     Director does not regard the current protection available as adequate under
the present circumstances, and Director and other officers and directors of the
Company may not be willing to serve or continue to serve as officers and
directors without additional protection; and 

     The Company desires to attract and retain the services of highly qualified
individuals, such as Director, to serve as officers and directors of the Company
and to indemnify its officers and directors so as to provide them with the
maximum protection permitted by law.

     The Company and Director hereby agree as follows:

     1.   Indemnification.
          --------------- 

          (a) Third Party Proceedings. The Company shall indemnify Director and
              -----------------------                                          
any partnership, corporation, trust or other entity of which Director is or was
a partner, shareholder, trustee, director, officer, employee or agent (Director
and each such partnership, corporation, trust or other entity being referred to
as an "Indemnitee") if Indemnitee is or was a party or is threatened to be made
a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the Company) by reason of the fact that Director is or was
a director, officer, employee or agent of the Company, or any subsidiary of the
Company, by reason of any action or inaction on the part of Director while an
officer or director or by reason of the fact that Director is or was serving at
the request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) actually and reasonably incurred by
Indemnitee in connection with such action, suit or proceeding, if Director
acted in good faith and in a manner Director reasonably believed to be in or not
opposed to the 
<PAGE>
 
best interests of the Company, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe Director's conduct was unlawful.
The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of no contest or its equivalent, shall
not, of itself, create a presumption that Director did not act in good faith and
in a manner which Director reasonably believed to be in or not opposed to the
best interests of the Company, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that Director's conduct was
unlawful.

          (b) Proceedings By or in the Right of the Company. The Company shall
              ---------------------------------------------                   
indemnify Indemnitee if Indemnitee was or is a party or is threatened to be
made a party to any threatened, pending or completed action or suit by or in the
right of the Company or any subsidiary of the Company to procure a judgment in
its favor by reason of the fact that Director is or was a director, officer,
employee or agent of the Company, or any subsidiary of the Company, by reason of
any action or inaction on the part of Director while an officer or director or
by reason of the fact that Director is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees) and, to the fullest extent permitted by law, amounts
paid in settlement, in each case to the extent actually and reasonably incurred
by Indemnitee in connection with the defense or settlement of such action or
suit, if Director acted in good faith and in a manner Director reasonably
believed to be in or not opposed to the best interests of the Company, except
that no indemnification shall be made in respect of any claim, issue or matter
as to which Director shall have been adjudged to be liable to the Company unless
and only to the extent that the Court of Chancery of the State of Delaware or
the court in which such action or suit was brought shall determine, upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, Indemnitee is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery of the State of
Delaware or such other court shall deem proper.

          (c) Mandatory Payment of Expenses. To the extent that Indemnitee has
              -----------------------------                                    
been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Sections 1 (a) and (b) or the defense of any claim,
issue or matter therein, Indemnitee shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by Indemnitee in
connection therewith.

     2.   Expenses: Indemnification Procedure.
          ----------------------------------- 

          (a) Advancement of Expenses. The Company shall advance all expenses
              -----------------------                                        
incurred by Indemnitee, and, to the fullest extent permitted by law, amounts
paid in settlement by Indemnitee, in connection with the investigation, defense,
settlement or appeal of any civil or criminal action, suit or proceeding
referenced in Section 1(a) or (b) hereof. Indemnitee hereby undertakes to repay
such amounts advanced only if, and to the extent that, it shall ultimately be
determined that Indemnitee is not entitled to be indemnified by the Company as
authorized hereby. The advances to be made hereunder shall be paid by the
Company to Indemnitee within 20 days following delivery of a written request
therefor by Indemnitee to the Company.

                                       2
<PAGE>
 
          (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a
              --------------------------------                         
condition precedent to his or its 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 President 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. Notice
shall be deemed received three business days after the date postmarked if sent
by domestic certified or registered mail, properly addressed; otherwise notice
shall be deemed received when such notice shall actually be received by the
Company. In addition, Indemnitee shall give the Company such information and
cooperation as it may reasonably require and as shall be within Indemnitee's
power.

          (c) Procedure. Any indemnification and advances provided for in
              ---------                                                  
Section 1 and this Section 2 shall be made no later than 45 days after receipt
of the written request of Indemnitee. If a claim under this Agreement, under any
statute, or under any provision of the Company's Certificate of Incorporation or
Bylaws providing for indemnification, is not paid in full by the Company within
45 days after a written request for payment thereof has first been received by
the Company, Indemnitee may, but need not, at any time thereafter bring an
action against the Company to recover the unpaid amount of the claim and,
subject to Section 12 of this Agreement, Indemnitee shall also be entitled to be
paid for the expenses (including attorneys' fees) of bringing such action. It
shall be a defense to any such action (other than an action brought to enforce a
claim for expenses incurred in connection with any action, suit or proceeding in
advance of its final disposition) that Indemnitee has not met the standards of
conduct which make it permissible under applicable law for the Company to
indemnify Indemnitee for the amount claimed, but the burden of proving such
defense shall be on the Company and Indemnitee shall be entitled to receive
interim payments of expenses pursuant to Subsection 2(a) unless and until such
defense may be finally adjudicated by court order or judgment from which no
further right of appeal exists. It is the parties' intention that if the Company
contests Indemnitee's right to indemnification, the question of Indemnitee's
right to indemnification shall be for the court to decide, and neither the
failure of the Company (including its Board of Directors, any committee or
subgroup of the Board of Directors, independent legal counsel, or its
stockholders) to have made a determination that indemnification of Indemnitee is
proper in the circumstances because Indemnitee has met the applicable standard
of conduct required by applicable law, nor an actual determination by the
Company (including its Board of Directors, any committee or subgroup of the
Board of Directors, independent legal counsel, or its stockholders) that
Indemnitee has not met such applicable standard of conduct, shall create a
presumption that Indemnitee has or has not met the applicable standard of
conduct.

          (d) Notice to Insurers. If, at the time of the receipt of a notice of
              ------------------                                               
a claim pursuant to Section 2(b) hereof, the Company has director and officer
liability insurance in effect, the Company shall give prompt notice of the
commencement of such proceeding 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 the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

                                       3

          (e) Selection of Counsel. In the event the Company shall be obligated
              --------------------                                             
under Section 2(a) hereof to pay the expenses of any proceeding against
Indemnitee, the Company, if appropriate, shall be entitled to assume the defense
of such proceeding, with counsel approved by Indemnitee, 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 proceeding, provided that (i) Indemnitee shall have the
right to employ his counsel in any such proceeding at Indemnitee's 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 may be a conflict of interest between the Company and Indemnitee in the
conduct of any such defense, or (C) the Company shall not, in fact, have
employed counsel to assume the defense of such proceeding, then the fees and
expenses of Indemnitee's counsel shall be at the expense of the Company.

  3.  Additional Indemnification Rights: Nonexclusivity.
      ------------------------------------------------ 

          (a) Scope. Notwithstanding any other provision of this Agreement, the
              -----                                                            
Company hereby agrees to indemnify the 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 by-laws 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, such changes shall be, ipso facto, within
the purview of Indemnitee's rights and Company's obligations, under this
Agreement. 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, such changes, 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.

          (b) Nonexclusivity. The indemnification provided by this Agreement
              --------------                                                
shall not be deemed exclusive of any rights to which Director or any other
Indemnitee may be entitled under the Company's certificate of incorporation, its
by-laws, any agreement, any vote of stockholders or disinterested directors, the
General Corporation Law of the State of Delaware, or otherwise, both as to
action in Director's official capacity and as to action in another capacity
while holding such office. The indemnification provided under this Agreement
shall continue as to Director and each other Indemnitee for any action taken or
not taken while Director is or was serving in an indemnified capacity even
though he may have ceased to serve in such capacity at the time of any action,
suit or other covered proceeding.

     4.   Partial Indemnification. If Indemnitee is entitled under any
          -----------------------                                     
provision of this Agreement to indemnification by the Company for some or a
portion of the expenses, judgments, fines or penalties actually or reasonably
incurred by Indemnitee in the investigation, defense, appeal or settlement of
any civil or criminal action, suit or proceeding, but not, however, for the

                                       4
<PAGE>
 
total amount thereof, the Company shall nevertheless indemnify Indemnitee for 
the portion of such expenses, judgments, fines or penalties to which Indemnitee
is entitled.

     5.   Mutual Acknowledgment. Both the Company and Director acknowledge that
          ---------------------
in certain instances federal law or applicable public policy may prohibit the
Company from indemnifying its directors and officers under this Agreement or
otherwise, in which event, notwithstanding any other provisions of this
Agreement to the contrary, the indemnification provided by this Agreement shall
be limited to such extent as is necessary to comply with applicable Federal law
or public policy. For example, the Company and the Director acknowledge that the
Securities and Exchange Commission has taken the position that indemnification
is not permissible for liabilities arising under certain federal securities
laws, and federal legislation prohibits indemnification for certain ERISA
violations. Director understands and acknowledges that in the event the Company
undertakes a public offering of its securities pursuant to a registration with
the Securities and Exchange Commission (the "SEC"), the Company may be required
to undertake with the SEC 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 Director or any other Indemnitee.

     6.   Officer and Director Liability Insurance.  The Company shall, from 
          ----------------------------------------
time to time, make the good faith determination whether or not it is practicable
for the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company with coverage for losses from wrongful acts, or to ensure the Company's
performance of its indemnification obligations under this Agreement. Among other
considerations, the Company will weigh the costs of obtaining such insurance
coverage against the protection afforded by such coverage. In all policies of
director and officer liability insurance, Director and each other Indemnitee
shall be named as an insured in such a manner as to provide Director the same
rights and benefits as are accorded to the most favorably insured of the
Company's directors, if the Indemnitee is a director; or of the Company's
officers, if the Indemnitee is not a director of the Company but is an officer,
or of the Company's key employees, if Indemnitee is not an officer or director
but is a key employee. Notwithstanding the foregoing, the Company shall have no
obligation to obtain or maintain such insurance if the Company determines in
good faith that such insurance is not reasonably available, the premium costs
for such insurance are disproportionate to the amount of coverage provided, the
coverage provided by such insurance is limited by exclusions so as to provide an
insufficient benefit, or Indemnitee is covered by similar insurance maintained
by a subsidiary or parent of the Company.

     7.   Severability.  Nothing in this Agreement is intended to require or 
          ------------   
shall be construed as requiring the Company to do or fail to do any act in 
violation of applicable law.  The Company's inability, pursuant to court order, 
to perform its obligations under this Agreement shall not constitute a breach of
this Agreement.  The provisions of this Agreement shall be severable as provided
in this Section 7.  If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall 
nevertheless indemnify Director and each other Indemnitee to the full extent 
permitted by any applicable portion of this Agreement that shall not have been 
invalidated, and the balance of this Agreement not so invalidated shall be 
enforceable in accordance with its terms.

                                       5

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

          (a) Claims Initiated by Indemnitee. To indemnify or advance expenses
              ------------------------------                                  
to Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by Indemnitee and not by way, of defense, except with respect to
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law, but such indemnification or
advancement of expenses may be provided by the Company in specific cases if the
Board of Directors finds it to be appropriate;

          (b) Lack of Good Faith. To indemnify Indemnitee for any expenses
              ------------------                                          
incurred by the 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 the
Indemnitee in such proceeding was not made in good faith or was frivolous;

          (c) Insured Claims. To indemnify Indemnitee for expenses or
              --------------                                         
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA, excise taxes or penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
officers' and directors' liability insurance maintained by the Company; or

          (d) Claims Under Section 166(b~. To indemnify Indemnitee for expenses
              --------------------------                                      
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

     9.   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, so that if Indemnitee is or was a director, officer, employee or agent
of such constituent corporation, or is or was serving at the request of such
constituent corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, 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 or agent of the Company which imposes
duties on, or involves services by, such director, officer, employee or agent
with

                                       6
<PAGE>
 
respect to an employee benefit plan, its participants, or 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.

     10. Counterparts. This Agreement may be executed in one or more
         ------------                                               
counterparts, each of which shall constitute an original.

     11. Successors and Assigns. This Agreement shall be binding upon the
         ----------------------                                          
Company and its successors and assigns, and shall inure to the benefit of
Director and each other Indemnitee and their respective estates, heirs,
successors, legal representatives and assigns.

     12. Attorneys' Fees. In the event that any action is instituted by
         ---------------                                               
Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all court costs and expenses, including
reasonable attorneys' fees, incurred by Indemnitee with respect to such action,
unless as a part of such action, the court of competent jurisdiction determines
that each of the material assertions made by Indemnitee as a basis for such
action were not made in good faith or were frivolous. In the event of an action
instituted by or in the name of the Company under this Agreement or to enforce
or interpret any of the terms of this Agreement, Indemnitee shall be entitled to
be paid all court costs and expenses, including attorneys' fees, incurred by
Indemnitee in defense of such action (including with respect to Indemnitee's
counterclaims and cross-claims made in such action), unless as a part of such
action the court determines that each of Indemnitee's material defenses to such
action were made in bad faith or were frivolous.

     13. Notice. All notices, requests, demands and other communications under
         ------
this Agreement shall be in writing and shall be deemed duly given on the third
business day after the date postmarked, if marked by domestic certified or
registered mail with postage prepaid, or, if delivered by other means, on the
date actual notice is received. Addresses for notice to either party are as
shown on the signature page of this Agreement, or as subsequently modified by
written notice.

     14.  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 brought only in the state courts of the State of Delaware.

     15.  Choice of Law. This Agreement shall be governed by and its provisions
          -------------                                                        
construed 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 Delaware.

                             VIGNETTE CORPORATION
                     1995 STOCK OPTION/STOCK ISSUANCE PLAN
                     -------------------------------------


                                  ARTICLE ONE

                              GENERAL PROVISIONS
                              ------------------

     I.   PURPOSE OF THE PLAN

          This 1995 Stock Option/Stock Issuance Plan is intended to promote the
interests of Vignette Corporation, a Delaware corporation, by providing eligible
persons with the opportunity to acquire a proprietary interest, or otherwise
increase their proprietary interest, in the Corporation as an incentive for them
to remain in the service of the Corporation.

          Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

     II.  STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into two (2) separate equity programs:

                    (i)  the Option Grant Program under which eligible persons
     may, at the discretion of the Plan Administrator, be granted options to
     purchase shares of Common Stock, and

                    (ii) the Stock Issuance Program under which eligible persons
     may, at the discretion of the Plan Administrator, be issued shares of
     Common Stock directly, either through the immediate purchase of such shares
     or as a bonus for services rendered the Corporation (or any Parent or
     Subsidiary).

          B.   The provisions of Articles One and Four shall apply to both the
equity programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.

     III. ADMINISTRATION OF THE PLAN

          A.   The Plan shall be administered by the Board.  However, any or all
administrative functions otherwise exercisable by the Board may be delegated to
the Committee.  Members of the Committee shall serve for such period of time as
the Board may determine and may be removed by the Board at any time.  The Board
may also at any time terminate the functions of the Committee and reassume all
powers and authority previously delegated to the Committee.

          B.   The Plan Administrator shall have full power and authority to
establish such rules and regulations as it may deem appropriate for proper
administration of the Plan and 
<PAGE>
 
to make such determinations under, and issue such interpretations of, the Plan
and any outstanding options or stock issuances thereunder as it may deem
necessary or advisable. Decisions of the Plan Administrator shall be final and
binding on all parties who have an interest in the Plan or any option or stock
issuance thereunder.

     IV.  ELIGIBILITY

          A.   The persons eligible to participate in the Plan are as follows:

                    (i)    Employees,

                    (ii)   non-employee members of the Board or the board of
     directors of any Parent or Subsidiary, and

                    (iii)  consultants and other independent advisors who
     provide services to the Corporation (or any Parent or Subsidiary).

          B.   The Plan Administrator shall have full authority to determine,
(i) with respect to the option grants under the Option Grant Program, which
eligible persons are to receive option grants, the time or times when such
option grants are to be made, the number of shares to be covered by each such
grant, the status of the granted option as either an Incentive Option or a Non-
Statutory Option, the time or times at which each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding and (ii) with
respect to stock issuances under the Stock Issuance Program, which eligible
persons are to receive stock issuances, the time or times when such issuances
are to be made, the number of shares to be issued to each Participant, the
vesting schedule (if any) applicable to the issued shares and the consideration
to be paid for such shares.

          C.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with the Option Grant Program or to effect stock
issuances in accordance with the Stock Issuance Program.

     V.   STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock.  The maximum number of shares of Common
Stock which may be issued over the term of the Plan shall not exceed 6,061,000
shares.

          B.   Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
expire or terminate for any reason prior to exercise in full or (ii) the options
are cancelled in accordance with the cancellation-regrant provisions of Article
Two.  All shares issued under the Plan, whether or not those shares are
subsequently repurchased or cancelled by the Corporation pursuant to its
repurchase or cancellation rights under the Plan, shall reduce on a share-for-
share basis the number of shares of Common Stock available for subsequent
issuance under the Plan.

                                       2
<PAGE>
 
          C.   Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and/or class of securities issuable
under the Plan and (ii) the number and/or class of securities and the exercise
price per share in effect under each outstanding option in order to prevent the
dilution or enlargement of benefits thereunder.  The adjustments determined by
the Plan Administrator shall be final, binding and conclusive.  In no event
shall any such adjustments be made in connection with the conversion of one or
more outstanding shares of the Corporation's preferred stock into shares of
Common Stock.

                                  ARTICLE TWO

                             OPTION GRANT PROGRAM
                             --------------------


     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
                                    --------                                  
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   EXERCISE PRICE.
               -------------- 

               1.   The exercise price per share shall be fixed by the Plan
Administrator and may be less than, equal to or greater than the Fair Market
Value per share of Common Stock on the option grant date.

               2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Four and the documents evidencing the option, be payable in cash or
check made payable to the Corporation. Should the Common Stock be registered
under Section 12(g) of the 1934 Act at the time the option is exercised, then
the exercise price may also be paid as follows:

                    (i)  in shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

                    (ii) to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to which
     the Optionee shall concurrently provide irrevocable written instructions to
     (a) a Corporation-designated brokerage firm to effect the immediate sale of
     the purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price

                                       3
<PAGE>
 
     payable for the purchased shares plus all applicable Federal, state and
     local income and employment taxes required to be withheld by the
     Corporation by reason of such exercise and (b) the Corporation to deliver
     the certificates for the purchased shares directly to such brokerage firm
     in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable at
               ----------------------------  
such time or times, during such period and for such number of shares as shall be
determined by the Plan Administrator and set forth in the documents evidencing
the option.  However, no option shall have a term in excess of ten (10) years
measured from the option grant date.

          C.   EFFECT OF TERMINATION OF SERVICE.
               -------------------------------- 

               1.   The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

                    (i)    Any option outstanding at the time of the Optionee's
     cessation of Service for any reason shall remain exercisable for such
     period of time thereafter as shall be determined by the Plan Administrator
     and set forth in the documents evidencing the option, but no such option
     shall be exercisable after the expiration of the option term.

                    (ii)   Each option held by the Optionee at the time of
     cessation of Service by reason of death shall become fully exercisable for
     all of the shares of the Common stock at the time subject to the option and
     each such option may be exercised for those Option Shares as fully-vested
     shares. Any option exercisable by the Optionee at the time of death may be
     exercised subsequently by the personal representative of the Optionee's
     estate or by the person or persons to whom the option is transferred
     pursuant to the Optionee's will or in accordance with the laws of descent
     and distribution.

                    (iii)  During the applicable post-Service exercise period,
     the option may not be exercised in the aggregate for more than the number
     of vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service. Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised. However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding to the extent the option is not otherwise at that time
     exercisable for vested shares.

                    (iv)   Should the Optionee's Service be terminated for
     Misconduct, then all outstanding options held by the Optionee shall
     terminate immediately and cease to be outstanding.

                    (v)    In the event of an Involuntary Termination following
     a Corporate Transaction, the provisions of Section III of this Article Two
     shall govern the period for which the outstanding options are to remain
     exercisable following the Optionee's cessation of Service and shall
     supersede any provisions to the contrary in this section.

               2.   The Plan Administrator shall have the discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

                    (i)    extend the period of time for which the option is to
     remain exercisable following the Optionee's cessation of Service from the
     period otherwise in effect for that option to such greater period of time
     as the Plan Administrator shall deem appropriate, but in no event beyond
     the expiration of the option term, and/or

                    (ii)   permit the option to be exercised, during the
     applicable post-Service exercise period, not only with respect to the
     number of vested shares of Common Stock for which such option is
     exercisable at the time of the Optionee's cessation of Service but also
     with respect to one or more additional installments in which the Optionee
     would have vested under the option had the Optionee continued in Service.

          D.   STOCKHOLDER RIGHTS.  The holder of an option shall have no
               ------------------                                        
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.   REPURCHASE RIGHTS.  The Plan Administrator shall have the
               -----------------                                        
discretion to grant options which are exercisable for unvested shares of Common
Stock.  Should the Optionee cease Service while holding such unvested shares,
the Corporation shall have the right to repurchase, at the exercise price paid
per share, any or all of those unvested shares.  The terms upon which such
repurchase right shall be exercisable (including the period and procedure for
exercise and the appropriate vesting schedule for the purchased shares) shall be
established by the Plan Administrator and set forth in the document evidencing
such repurchase right.

          F.   FIRST REFUSAL RIGHTS.  Until such time as the Common Stock is
               --------------------                                         
first registered under Section 12(g) of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Option Grant Program.  Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

          G.   LIMITED TRANSFERABILITY OF OPTIONS.  During the lifetime of the
               ----------------------------------                             
Optionee, the option shall be exercisable only by the Optionee and shall not be
assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death.  However, a Non-Statutory Option
may be assigned in whole or in part during the Optionee's 

                                       5
<PAGE>
 
lifetime in accordance with the terms of a Qualified Domestic Relations Order.
The assigned portion may only be exercised by the person or persons who acquire
a proprietary interest in the option pursuant to such Qualified Domestic
Relations Order. The terms applicable to the assigned portion shall be the same
as those in effect for the option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Plan Administrator
may deem appropriate.

     II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Four shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall not be subject to the terms of this Section II.
                                 ---                                            

          A.   ELIGIBILITY.  Incentive Options may only be granted to Employees.
               -----------                                                      

          B.   EXERCISE PRICE.  The exercise price per share shall not be less
               --------------                                                 
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

          C.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the shares
               -----------------                                                
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one (1) calendar year
shall not exceed the sum of One Hundred Thousand Dollars ($100,000).  To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

          D.   10% STOCKHOLDER.  If any Employee to whom an Incentive Option is
               ---------------                                                 
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date and the option term shall not exceed five
(5) years measured from the option grant date.

     III. CORPORATE TRANSACTION

          A.   In the event of any Corporate Transaction, each outstanding
option shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
fully exercisable for all of the shares of Common Stock at the time subject to
such option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock. However, an outstanding option shall not so accelerate
if and to the extent: (i) such option is, in connection with the Corporate
Transaction, either to be assumed by the successor corporation (or parent
thereof) or to be replaced with a comparable option to purchase shares of the
capital stock of the successor corporation (or parent thereof), (ii) such option
is to be replaced with a cash incentive program of the successor corporation
which

                                       6
<PAGE>
 
preserves the spread existing on the unvested option shares at the time of the
Corporate Transaction and provides for subsequent payout in accordance with the
same vesting schedule applicable to such option or (iii) the acceleration of
such option is subject to other limitations imposed by the Plan Administrator at
the time of the option grant. The determination of option comparability under
clause (i) above shall be made by the Plan Administrator, and its determination
shall be final, binding and conclusive.

          B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are to be assigned to the
successor corporation (or parent thereof) in connection with such Corporate
Transaction or (ii) such accelerated vesting is precluded by other limitations
imposed by the Plan Administrator at the time the repurchase right is issued.

          C.   Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply  to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, provided the aggregate exercise price payable for such
                         --------                                              
securities shall remain the same.

          E.   Any options which are assumed or replaced in the Corporate
Transaction and do not otherwise accelerate at that time shall automatically
accelerate (and any of the Corporation's outstanding repurchase rights which do
not otherwise terminate at the time of the Corporate Transaction shall
automatically terminate and the shares of Common Stock subject to those
terminated rights shall immediately vest in full) in the event the Optionee's
Service should subsequently terminate by reason of an Involuntary Termination
within eighteen (18) months following the effective date of such Corporate
Transaction.  Any options so accelerated shall remain exercisable for fully-
vested shares until the earlier of (i) the expiration of the option term or (ii)
                        -------                                                 
the expiration of the one (1)-year period measured from the effective date of
the Involuntary Termination.

          F.   The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to provide for the automatic acceleration of one or more
outstanding options (and the automatic termination of one or more outstanding
repurchase rights with the immediate vesting of the shares of Common Stock
subject to those rights) upon the occurrence of a Corporate Transaction, whether
or not those options are to be assumed or replaced (or those repurchase rights
are to be assigned) in the Corporate Transaction.  The Plan Administrator shall
also have the discretion to grant options 

                                       7
<PAGE>
 
which do not accelerate (and to provide for repurchase rights which do not
terminate) upon a Corporate Transaction or an Involuntary Termination following
a Corporate Transaction.

          G.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
($100,000) limitation is not exceeded. To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a Non-
Statutory Option under the Federal tax laws.

          H.   The grant of options under the Plan shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Option Grant Program
and to grant in substitution new options covering the same or different number
of shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new grant date.

                            STOCK ISSUANCE PROGRAM
                            ----------------------


     I.   STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.

          A.   PURCHASE PRICE.
               -------------- 

               1.   The purchase price per share shall be fixed by the Plan
Administrator  and may be less than, equal to or greater than the Fair Market
Value per share of Common Stock on the stock issuance date.

               2.   Subject to the provisions of Section I of Article Four,
shares of Common Stock may be issued under the Stock Issuance Program for one or
both of the following items of consideration which the Plan Administrator may
deem appropriate in each individual instance:

                    (i)  cash or check made payable to the Corporation, or

                                       8
<PAGE>
 
                    (ii)   past services rendered to the Corporation (or any
     Parent or Subsidiary).

          B.   VESTING PROVISIONS.
               ------------------ 

               1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives. The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program, namely:

               (i)    the Service period to be completed by the Participant or
     the performance objectives to be attained,

               (ii)   the number of installments in which the shares are to
     vest,

               (iii)  the interval or intervals (if any) which are to lapse
     between installments, and

               (iv)   the effect which death, Permanent Disability or other
     event designated by the Plan Administrator is to have upon the vesting
     schedule,

shall be determined by the Plan Administrator and incorporated into the Stock
Issuance Agreement.

               2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

               3.   The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested. Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

               4.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested

                                       9
<PAGE>
 
shares of Common Stock, then those shares shall be immediately surrendered to
the Corporation for cancellation, and the Participant shall have no further
stockholder rights with respect to those shares. To the extent the surrendered
shares were previously issued to the Participant for consideration paid in cash
or cash equivalent (including the Participant's purchase-money indebtedness),
the Corporation shall repay to the Participant the cash consideration paid for
the surrendered shares and shall cancel the unpaid principal balance of any
outstanding purchase-money note of the Participant attributable to the
surrendered shares.

               5.   The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock (or
other assets attributable thereto) which would otherwise occur upon the
cessation of the Participant's Service or the non-attainment of the performance
objectives applicable to such shares. Such waiver shall result in the immediate
vesting of the Participant's interest in the shares of Common Stock as to which
the waiver applies. Such waiver may be effected at any time, whether before or
after the Participant's cessation of Service or the attainment or non-attainment
of the applicable performance objectives.

          C.   FIRST REFUSAL RIGHTS.  Until such time as the Common Stock is
               --------------------                                         
first registered under Section 12(g) of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Participant (or any successor in interest) of any shares of Common Stock issued
under the Stock Issuance Program.  Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

     II.  CORPORATE TRANSACTION

          A.   All of the outstanding cancellation rights under the Stock
Issuance Program shall terminate automatically, and all the shares of Common
Stock subject to those terminated rights shall immediately vest in full, in the
event of any Corporate Transaction, except to the extent (i) those cancellation
rights are assigned to the successor corporation (or parent thereof) in
connection with such Corporate Transaction or (ii) such accelerated vesting is
precluded by other limitations imposed in the Stock Issuance Agreement.

          B.   Any cancellation rights that are assigned in the Corporate
Transaction shall automatically terminate, and the shares of Common Stock
subject to those terminated rights shall immediately vest in full, in the event
the Participant's Service should subsequently terminate by reason of an
Involuntary Termination within eighteen (18) months following the effective date
of such Corporate Transaction.

          C.   The Plan Administrator shall have the discretion, exercisable
either at the time the unvested shares are issued or at any time while the
Corporation's cancellation right remains outstanding, to provide for the
automatic termination of one or more outstanding cancellation rights, and the
immediate vesting of the shares of Common Stock subject to those rights, upon
the occurrence of a Corporate Transaction, whether or not those cancellation
rights are assigned in connection with the Corporate Transaction.

     III. SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                                 ARTICLE FOUR

                                 MISCELLANEOUS
                                 -------------


     I.   FINANCING

          A.   The Plan Administrator may permit any Optionee or Participant to
pay the option exercise price or the purchase price for shares issued under the
Plan by delivering a promissory note payable in one or more installments.  The
terms of any such promissory note (including the interest rate and the terms of
repayment) shall be established by the Plan Administrator in its sole
discretion.  Promissory notes may be authorized with or without security or
collateral.  In all events, the maximum credit available to the Optionee or
Participant may not exceed the sum of (i) the aggregate option exercise price or
                               ---                                              
purchase price payable for the purchased shares plus (ii) any Federal, state and
local income and employment tax liability incurred by the Optionee or the
Participant in connection with the option exercise or share purchase.

          B.   The Plan Administrator may, in its discretion, determine that one
or more such promissory notes shall be subject to forgiveness by the Corporation
in whole or in part upon such terms as the Plan Administrator may deem
appropriate.

     II.  EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan shall become effective when adopted by the Board, but no
option granted under the Plan may be exercised, and no shares shall be issued
under the Plan, until the Plan is approved by the Corporation's stockholders.
If such stockholder approval is not obtained within twelve (12) months after the
date of the Board's adoption of the Plan, then all options previously granted
under the Plan shall terminate and cease to be outstanding, and no further
options shall be granted and no shares shall be issued under the Plan.  Subject
to such limitation, the Plan Administrator may grant options and issue shares
under the Plan at any time after the effective date of the Plan and before the
date fixed herein for termination of the Plan.

          B.   The Plan shall terminate upon the earliest of (i) the expiration
                                                 --------                      
of the ten (10)-year period measured from the date the Plan is adopted by the
Board, (ii) the date on which all shares available for issuance under the Plan
shall have been issued pursuant to the exercise of options or the issuance of
shares (whether vested or unvested) under the Plan or (iii) the termination of
all outstanding options in connection with a Corporate Transaction.  Upon such
Plan termination, all options and unvested stock issuances outstanding under the
Plan shall 

                                       11
<PAGE>
 
continue to have full force and effect in accordance with the provisions of the
documents evidencing such options or issuances.

     III. AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects. However, no such amendment
or modification shall adversely affect any rights and obligations with respect
to options or unvested stock issuances at the time outstanding under the Plan,
unless the Optionee or the Participant consents to such amendment or
modification. In addition, the Board shall not, without the approval of the
Corporation's stockholders, (i) increase the maximum number of shares issuable
under the Plan, except for permissible adjustments in the event of certain
changes in the Corporation's capitalization, (ii) materially modify the
eligibility requirements for Plan participation or (iii) materially increase the
benefits accruing to Plan participants.

          B.   Options to purchase shares of Common Stock may be granted under
the Plan and shares of Common Stock may be issued under the Plan that are in
each instance in excess of the number of shares then available for issuance
under the Plan, provided any excess shares actually issued  under the Plan are
                --------                                                      
held in escrow until there is obtained stockholder approval of an amendment
sufficiently increasing the number of shares of Common Stock available for
issuance under the Plan.  If such stockholder approval is not obtained within
twelve (12) months after the date the first such excess grants or issuances are
made, then (i) any unexercised options granted on the basis of such excess
shares shall terminate and cease to be outstanding and (ii) the Corporation
shall promptly refund to the Optionees and the Participants the exercise or
purchase price paid for any excess shares issued under the Plan and held in
escrow, together with interest (at the applicable Short-Term Federal Rate) for
the period the shares were held in escrow, and such shares shall thereupon be
automatically cancelled and cease to be outstanding.

     IV.  USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     V.   WITHHOLDING

          The Corporation's obligation to deliver shares of Common Stock upon
the exercise of any options or upon the issuance or vesting of such shares
issued under the Plan shall be subject to the satisfaction of all applicable
Federal, state and local income and employment tax withholding requirements.

     VI.  REGULATORY APPROVALS

          The implementation of the Plan, the granting of any option under the
Plan and the issuance of any shares of Common Stock (i) upon the exercise of any
option or (ii) under the Stock Issuance Program shall be subject to the
Corporation's procurement of all approvals and 

                                       12
<PAGE>
 
permits required by regulatory authorities having jurisdiction over the Plan,
the options granted under it and the shares of Common Stock issued pursuant to
it.

     VII. NO EMPLOYMENT OR SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

                                   APPENDIX
                                   --------

RECITALS
- --------

     A.   The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or the board
of directors of any Parent or Subsidiary and consultants and other independent
advisors who provide services to the Corporation (or any Parent or Subsidiary).

assigned to them in the attached Appendix.

          NOW, THEREFORE, it is hereby agreed as follows:

business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5, 6 or 17.

          3.   LIMITED TRANSFERABILITY. This option shall be neither

               (b)  Optionee shall, in accordance with the Vesting Schedule,

Service. Vesting in the Option Shares may be accelerated pursuant to the
provisions of Paragraph 6. In no event, however, shall any additional Option
Shares vest following Optionee's cessation of Service.

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

Expiration Date and the Vesting Schedule shall accelerate should any of the
following provisions become applicable:

     at any time after the Expiration Date.

                    (ii)   Should Optionee cease Service by reason of death,
     then all the Option Shares at the time subject to this option shall vest so

     Shares as fully-vested shares.

                    (iii)  Should Optionee die while this option is outstanding,
     then the personal representative of Optionee's estate or the person or
     persons to whom the option is transferred pursuant to Optionee's will or in
     accordance with the laws of descent and distribution shall have the right
     to exercise this option. Such right shall lapse and this option shall cease
     to be outstanding upon the earlier of (A) the expiration of the twelve 
                                -------
     (12)-month period measured from the date of Optionee's death or (B) the
     Expiration Date.

                    (iv)   Should Optionee cease Service by reason of Permanent
     Disability while this option is outstanding, then Optionee shall have a
     period of twelve (12) months (commencing with the date of such cessation of
     Service) during which to exercise this option. In no event shall this
     option be exercisable at any time after the Expiration Date.

<PAGE>
 
                    (v)    Should Optionee's Service be terminated for
     Misconduct, then this option shall terminate immediately and cease to
     remain outstanding.

                    (vi)   During the limited post-Service exercise period, this
     option may not be exercised in the aggregate for more than the number of
     Option Shares in which Optionee is, at the time of Optionee's cessation of
     Service, vested in accordance with the Vesting Schedule. Upon the
     expiration of such limited exercise period or (if earlier) upon the
     Expiration Date, this option shall terminate and cease to be outstanding
     for any vested Option Shares for which the option has not been exercised.
     To the extent Optionee is not vested in the Option Shares at the time of
     Optionee's cessation of Service, this option shall immediately terminate
     and cease to be outstanding with respect to those shares.

                    (vii)  In the event of a Corporate Transaction, the
     provisions of Paragraph 6 shall govern the period for which this option is
     to remain exercisable following Optionee's cessation of Service and shall
     supersede any provisions to the contrary in this paragraph.

          6.   SPECIAL TERMINATION OF OPTION.
               ----------------------------- 

               (a)  All the Option Shares subject to this option at the time of
a Corporate Transaction but not otherwise vested shall automatically vest and
the Corporation's repurchase rights with respect to those Option Shares shall
immediately terminate so that this option shall, immediately prior to the
effective date of the Corporate Transaction, become exercisable for all of the
Option Shares as fully-vested shares of Common Stock and may be exercised for
any or all of those Option Shares. No such accelerated vesting of the Option
Shares, however, shall occur if and to the extent: (i) this option is, in
connection with the Corporate Transaction, either to be assumed by the successor
corporation (or parent thereof) or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation (or parent
thereof), and the Corporation's repurchase rights with respect to the unvested
Option Shares are to be assigned to such successor corporation (or parent
thereof) or (ii) this option is to be replaced with a cash incentive program of
the successor corporation which preserves the spread existing on the unvested
Option Shares at the time of the Corporate Transaction (the excess of the Fair
Market Value of those Option Shares over the Exercise Price payable for such
shares) and provides for subsequent payout in accordance with the Vesting
Schedule.

               (b)  Immediately following the Corporate Transaction, this option
shall terminate and cease to be outstanding, except to the extent assumed by the
successor corporation (or parent thereof) in connection with the Corporate
Transaction.

               (c)  If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to

                                      3.
<PAGE>
 
apply to the number and class of securities which would have been issuable to
Optionee in consummation of such Corporate Transaction had the option been
exercised immediately prior to such Corporate Transaction, and appropriate
adjustments shall also be made to the Exercise Price, provided the aggregate
                                                      --------
Exercise Price shall remain the same.

               (d)  Should there occur an Involuntary Termination of Optionee's
Service within eighteen (18) months following a Corporate Transaction in which
this option is assumed or replaced and the Corporation's repurchase rights with
respect to the unvested Option Shares are assigned, all the Option Shares at the
time subject to this option but not otherwise vested shall automatically vest
and the Corporation's repurchase rights with respect to those Option Shares
shall terminate so that this option shall immediately become exercisable for all
those Option Shares as fully-vested shares of Common Stock and may be exercised
for any or all of those vested Option Shares at any time prior to the earlier of
                                                                      -------
(i) the Expiration Date or (ii) the expiration of the one (l)-year period
measured from the date of such Involuntary Termination.

               (e)  This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

          7.   ADJUSTMENT IN OPTION SHARES.  Should any change be made to the
               ---------------------------                                   
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be made to (i) the total number
and/or class of securities subject to this option and (ii) the Exercise Price in
order to reflect such change and thereby preclude a dilution or enlargement of
benefits hereunder.

          8.   STOCKHOLDER RIGHTS.  The holder of this option shall not have any
               ------------------                                               
stockholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares.

          9.   MANNER OF EXERCISING OPTION.
               --------------------------- 

               (a)  In order to exercise this option with respect to all or any
part of the Option Shares for which this option is at the time exercisable,
Optionee (or any other person or persons exercising the option) must take the
following actions:

                         (i)    Execute and deliver to the Corporation a
     Purchase Agreement for the Option Shares for which the option is exercised.

     purchased shares in one or more of the following forms:

                         (A)    cash or check made payable to the Corporation;
          or

                                      4.
<PAGE>
 
                         (B)    a promissory note payable to the Corporation,
          but only to the extent authorized by the Plan Administrator in
          accordance with Paragraph 14.

               Should the Common Stock be registered under Section 12(g) of the
          1934 Act at the time the option is exercised, then the Exercise Price
          may also be paid as follows:

                         (C)    in shares of Common Stock held by Optionee (or
          any other person or persons exercising the option) for the requisite
          period necessary to avoid a charge to the Corporation's earnings for
          financial reporting purposes and valued at Fair Market Value on the
          Exercise Date; or

                         (D)    to the extent the option is exercised for vested
          Option Shares, through a special sale and remittance procedure
          pursuant to which Optionee (or any other person or persons exercising
          the option) shall concurrently provide irrevocable written
          instructions (I) to a Corporation-designated brokerage firm to effect
          the immediate sale of the purchased shares and remit to the
          Corporation, out of the sale proceeds available on the settlement
          date, sufficient funds to cover the aggregate Exercise Price payable
          for the purchased shares plus all applicable Federal, state and local
          income and employment taxes required to be withheld by the Corporation
          by reason of such exercise and (II) to the Corporation to deliver the
          certificates for the purchased shares directly to such brokerage firm
          in order to complete the sale.

               Except to the extent the sale and remittance procedure is
          utilized in connection with the option exercise, payment of the
          Exercise Price must accompany the Purchase Agreement delivered to the
          Corporation in connection with the option exercise.

                    (iii)  Furnish to the Corporation appropriate documentation
     that the person or persons exercising the option (if other than Optionee)
     have the right to exercise this option.

                    (iv)   Execute and deliver to the Corporation such written
     representations as may be requested by the Corporation in order for it to
     comply with the applicable requirements of Federal and state securities
     laws.

                    (v)    Make appropriate arrangements with the Corporation
     (or Parent or Subsidiary employing or retaining Optionee) for the
     satisfaction of all Federal, state and local income and employment tax
     withholding requirements applicable to the option exercise.

                                      5.
<PAGE>
 
               (b)  As soon as practical after the Exercise Date, the
Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate for the purchased Option Shares,
with the appropriate legends affixed thereto. To the extent any such Option
Shares are unvested, the certificates for those Option Shares shall be endorsed
with an appropriate legend evidencing the Corporation's repurchase rights and
may be held in escrow with the Corporation until such shares vest.

               (c)  In no event may this option be exercised for any fractional
shares.

          10.  REPURCHASE RIGHTS.  ALL OPTION SHARES ACQUIRED UPON THE EXERCISE
               -----------------

          11.  COMPLIANCE WITH LAWS AND REGULATIONS.
               ------------------------------------ 

               (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

               (b)  The inability of the Corporation to obtain approval from any
regulatory body having authority deemed by the Corporation to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Corporation of any liability with respect to the non-issuance or
sale of the Common Stock as to which such approval shall not have been obtained.
The Corporation, however, shall use its best efforts to obtain all such
approvals.

         12.   SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided

               ------------                                                     
made and granted pursuant to the Plan and are in all respects limited by and

respect to any question or issue arising under the Plan or this Agreement shall

               -------------                                                  
of this Agreement shall be governed by the laws of the State of Texas without
resort to that State's conflict-of-laws rules.

          17.  STOCKHOLDER APPROVAL.
               -------------------- 

               (a)  The grant of this option is subject to approval of the Plan
by the Corporation's stockholders within twelve (12) months after the adoption
of the Plan by the Board. Notwithstanding any provision of this Agreement to the
                          ------------------------------------------------------
contrary, this option may not be exercised in whole or in part until such
- -------------------------------------------------------------------------
stockholder approval is obtained.  In the event that such stockholder approval
- --------------------------------                                              
is not obtained, then this option shall terminate in its entirety and Optionee
shall have no further rights to acquire any Option Shares hereunder.

               (b)  If the Option Shares covered by this Agreement exceed, as of
the Grant Date, the number of shares of Common Stock which may without
stockholder approval be issued under the Plan, then this option shall be void
with respect to such excess shares, unless stockholder approval of an amendment
sufficiently increasing the number of shares of Common Stock issuable under the
Plan is obtained in accordance with the provisions of the Plan.

          18.  ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION.  In the event
               --------------------------------------------------               
this option is designated an Incentive Option in the Grant Notice, the following
terms and conditions shall also apply to the grant:

                    (i)  This option shall cease to qualify for favorable tax
     treatment as an Incentive Option if (and to the extent) this option is
     exercised for one or more Option Shares: (A) more than three (3) months
     after the date Optionee ceases to be an Employee for any reason other than
     death or

____________________________
/1/  Authorization of payment of the Exercise Price by a promissory note

may, under currently proposed Treasury Regulations, result in the loss of
incentive stock option treatment under the Federal tax laws.

<PAGE>
 
Permanent Disability or (B) more than twelve (12) months after the date Optionee
ceases to be an Employee by reason of Permanent Disability.

                    (ii)   This option shall not become exercisable in the
     calendar year in which granted if (and to the extent) the aggregate Fair
     Market Value (determined at the Grant Date) of the Common Stock for which
     this option would otherwise first become exercisable in such calendar year
     would, when added to the aggregate value (determined as of the respective
     date or dates of grant) of the Common Stock and any other securities for
     which one or more other Incentive Options granted to Optionee prior to the
     Grant Date (whether under the Plan or any other option plan of the
     Corporation or any Parent or Subsidiary) first become exercisable during
     the same calendar year, exceed One Hundred Thousand Dollars ($100,000) in
     the aggregate. To the extent the exercisability of this option is deferred
     by reason of the foregoing limitation, the deferred portion shall become
     exercisable in the first calendar year or years thereafter in which the One
     Hundred Thousand Dollar ($100,000) limitation of this Paragraph 18(ii)
     would not be contravened, but such deferral shall in all events end
     immediately prior to the effective date of a Corporate Transaction in which
     this option is not to be assumed or the Optionee's Involuntary Termination
     in connection with a Corporate Transaction, whereupon the option shall
     become immediately exercisable as a Non-Statutory Option for the deferred
     portion of the Option Shares.

                    (iii)  Should Optionee hold, in addition to this option, one
     or more other options to purchase Common Stock which become exercisable for
     the first time in the same calendar year as this option, then the foregoing
     limitations on the exercisability of such options as Incentive Options
     shall be applied on the basis of the order in which such options are
     granted.

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

          1.   PURCHASE.  Participant hereby purchases  ____________ shares of
               --------

               -------                                                          
Corporation,  Participant shall pay the Purchase Price for the Purchased Shares
in cash or check payable to the Corporation and shall deliver a duly-executed

registered under the 1933 Act and are being issued to Participant in reliance
upon the exemption from such registration provided by SEC Rule 701 for stock
issuances under compensatory benefit plans such as the Plan.  Participant hereby
confirms that Participant has been informed that the Purchased Shares are
restricted securities under the 1933 Act and may not be resold or transferred
unless the Purchased Shares are first registered under the Federal securities
laws or unless an exemption from such registration is available.  Accordingly,
Participant hereby acknowledges that Participant is prepared to hold the
Purchased Shares for an indefinite period and that Participant is aware that SEC
Rule 144 issued under the 1933 Act which exempts certain resales of unrestricted
securities is not presently available to exempt the resale of the Purchased
Shares from the registration requirements of the 1933 Act.

               (iii)  Participant shall have provided the Corporation with
     written assurances, in form and substance satisfactory to the Corporation,
     that (a) the proposed disposition does not require registration of the
     Purchased Shares under the 1933 Act or (b) all appropriate action necessary
     for compliance with the registration requirements of the 1933 Act or any
     exemption from registration available under the 1933 Act (including Rule
     144) has been taken.

          The Corporation shall not be required (i) to transfer on its books any
                                ---                                             
Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement or (ii) to treat as the owner of the Purchased
                             --                                            
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

Shares shall be endorsed with the following restrictive legends:

     registered under the Securities Act of 1933. The shares may not be sold or
     offered for sale in the absence of (a) an effective registration statement
     for the shares under such Act, (b) a 'no action' letter of the Securities
     and Exchange Commission with respect to such sale or offer or (c)
     satisfactory assurances to the Corporation that registration under such Act
     is not required with respect to such sale or offer."

               (ii) "The shares represented by this certificate are unvested and
     are subject to certain repurchase rights and rights of first refusal
     granted to the Corporation and accordingly may not be sold, assigned,
     transferred, encumbered, or in any manner disposed of except in conformity
     with the terms of a written agreement dated ____________, 199__ between the

writing to the Corporation that such person is bound by the provisions of this

only if the officers and directors of the Corporation are also subject to
- -------
similar restrictions.

               (c)  Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

               (d)  In order to enforce the Market Stand-Off, the Corporation
may impose stop-transfer instructions with respect to the Purchased Shares until
the end of the applicable stand-off period.

following a Corporate Transaction, such right shall apply to the new capital
stock or other property (including any cash payments) received in exchange for
the Purchased Shares in consummation of the Corporate Transaction, but only to

refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the Purchased Shares in which Participant has vested in accordance
with the Vesting Schedule.  For purposes of this Article E, the term "transfer"
shall include any sale, assignment, pledge, encumbrance or other disposition of
the Purchased Shares intended to be made by Owner, but shall not include any
Permitted Transfer.

          2.   NOTICE OF INTENDED DISPOSITION.  In the event any Owner of
               ------------------------------                            
Purchased Shares in which Participant has vested desires to accept a bona fide
third-party offer for the transfer of any or all of such shares (the Purchased
Shares subject to such offer to be hereinafter referred to as the "Target
Shares"), Owner shall promptly (i) deliver to the Corporation written notice
(the "Disposition Notice") of the terms of the offer, including the purchase
price and the identity of the third-party offeror, and (ii) provide satisfactory
proof that the disposition of the Target Shares to such third-party offeror
would not be in contravention of the provisions set forth in Articles B and C.

the right to repurchase any or all of the Target Shares subject to the
Disposition Notice upon the same terms as those specified therein or upon such
other terms (not materially different from those specified in the Disposition
Notice) to which Owner consents.  Such right shall be exercisable by delivery of
written notice (the "Exercise Notice") to Owner prior to the expiration of the
forty-five (45)-day exercise period.  If such right is exercised with respect to
all the Target Shares, then the 

                                       5
<PAGE>
 
Corporation shall effect the repurchase of such shares, including payment of the
purchase price, not more than fifteen (15) business days after delivery of the
Exercise Notice; and at such time the certificates repre-senting the Target
Shares shall be delivered to the Corporation.

          Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property.  If Owner and the Corporation
cannot agree on such cash value within thirty (30) days after the Corporation's
receipt of the Disposition Notice, the valuation shall be made by an appraiser
of recognized standing selected by Owner and the Corporation or, if they cannot
agree on an appraiser within forty-five (45) days after the Corporation's
receipt of the Disposition Notice, each shall select an appraiser of recognized
standing and the two (2) appraisers shall designate a third appraiser of
recognized standing, whose appraisal shall be determinative of such value.  The
cost of such appraisal shall be shared equally by Owner and the Corporation.
The closing shall then be held on the later of (i) the fifteenth (15th) business
                                      -----                                     
day following delivery of the Exercise Notice or (ii) the fifteenth (15th)
business day after such valuation shall have been made.

          4.   NON-EXERCISE OF THE FIRST REFUSAL RIGHT.  In the event the
               ---------------------------------------                   
Exercise Notice is not given to Owner prior to the expiration of the forty-five
(45)-day exercise period, Owner shall have a period of thirty (30) days
thereafter in which to sell or otherwise dispose of the Target Shares to the
third-party offeror identified in the Disposition Notice upon terms (including
the purchase price) no more favorable to such third-party offeror than those
specified in the Disposition Notice; provided, however, that any such sale or
                                     --------                                
disposition must not be effected in contravention of the provisions of Articles
B and C.  The third-party offeror shall acquire the Target Shares free and clear
of the Repurchase Right and the First Refusal Right, but the acquired shares
shall remain subject to the provisions of Article B and Paragraph C.3.  In the
event Owner does not effect such sale or disposition of the Target Shares within
the specified thirty (30)-day period, the First Refusal Right shall continue to
be applicable to any subsequent disposition of the Target Shares by Owner until
such right lapses.

          5.   PARTIAL EXERCISE OF THE FIRST REFUSAL RIGHT.  In the event the
               -------------------------------------------                   
Corporation makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within fifteen (15) business days after Owner's receipt of the
Exercise Notice, to effect the sale of the Target Shares pursuant to either of
the following alternatives:

               (i)  sale or other disposition of all the Target Shares to the
     third-party offeror identified in the Disposition Notice, but in full
     compliance with the requirements of Paragraph E.4, as if the Corporation
     did not exercise the First Refusal Right; or

               (ii) sale to the Corporation of the portion of the Target Shares
     which the Corporation has elected to purchase, such sale to be effected in
     substantial conformity with the provisions of Paragraph E.3. The First
     Refusal Right shall

                                       6
<PAGE>
 
continue to be applicable to any subsequent disposition of the remaining Target
Shares until such right lapses.

          Failure of Owner to deliver timely notification to the Corporation
shall be deemed to be an election by Owner to sell the Target Shares pursuant to
alternative (i) above.

          6.   RECAPITALIZATION/REORGANIZATION.
               ------------------------------- 

               (a)  Any new, substituted or additional securities or other
property which is by reason of any Recapitalization distributed with respect to
the Purchased Shares shall be immediately subject to the First Refusal Right,
but only to the extent the Purchased Shares are at the time covered by such
right.

               (b)  In the event of a Reorganization, the First Refusal Right
shall remain in full force and effect and shall apply to the new capital stock
or other property received in exchange for the Purchased Shares in consummation
of the Reorganization, but only to the extent the Purchased Shares are at the
time covered by such right.

          7.   LAPSE.  The First Refusal Right shall lapse upon the earliest to
               -----                                                --------   
occur of (i) the first date on which shares of the Common Stock are held of
record by more than five hundred (500) persons, (ii) a determination is made by
the Board that a public market exists for the outstanding shares of Common Stock
or (iii) a firm commitment underwritten public offering, pursuant to an
effective registration statement under the 1933 Act, covering the offer and sale
of the Common Stock in the aggregate amount of at least ten million dollars
($10,000,000).  However, the Market Stand-Off shall continue to remain in full
force and effect following the lapse of the First Refusal Right.

     F.   SPECIAL TAX ELECTION
          --------------------

          1.   SECTION 83(B) ELECTION.  Under Code Section 83, the excess of the
               -----------------------
fair market value of the Purchased Shares on the date any forfeiture
restrictions applicable to such shares lapse over the Purchase Price paid for
such shares will be reportable as ordinary income on the lapse date.  For this
purpose, the term "forfeiture restrictions" includes the right of the
Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right.
Participant may elect under Code Section 83(b) to be taxed at the time the
Purchased Shares are acquired, rather than when and as such Purchased Shares
cease to be subject to such forfeiture restrictions.  Such election must be
filed with the Internal Revenue Service within thirty (30) days after the date
of this Agreement.  Even if the fair market value of the Purchased Shares on the
date of this Agreement equals the Purchase Price paid (and thus no tax is
payable), the election must be made to avoid adverse tax consequences in the
future.  THE FORM FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO.
PARTICIPANT UNDERSTANDS THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE
THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE
FORFEITURE RESTRICTIONS LAPSE.

                           STOCK PURCHASE AGREEMENT
                           ------------------------


     AGREEMENT made as of this ______ day of ___________ 19____, by and between
Vignette Corporation, a Delaware corporation, ____________________    _____,
Optionee under the Corporation's 1995 Stock Option/Stock Issuance Plan, and
__________      __________, Optionee's spouse.

     All capitalized terms in this Agreement shall have the meaning assigned to
them in this Agreement or in the attached Appendix.

     A.   EXERCISE OF OPTION
          ------------------

          1.   EXERCISE.  Optionee hereby purchases ____  ______ shares of 
               --------                                                
Common Stock (the "Purchased Shares") pursuant to that certain option (the
"Option") granted Optionee on _______________, 199__ (the "Grant Date") to
purchase up to __________ shares of Common Stock under the Plan at the exercise
price of $__________ per share (the "Exercise Price").

          2.  PAYMENT.  Concurrently with the delivery of this Agreement to the
              -------                                                          
Corporation, Optionee shall pay the Exercise Price for the Purchased Shares in
accordance with the provisions of the Option Agreement and shall deliver
whatever additional documents may be required by the Option Agreement as a
condition for exercise, together with a duly-executed blank Assignment Separate
from Certificate (in the form attached hereto as Exhibit I) with respect to the
Purchased Shares.

          3.   STOCKHOLDER RIGHTS. Until such time as the Corporation exercises
               ------------------  
the Repurchase Right or the First Refusal Right, Optionee (or any successor in
interest) shall have all the rights of a stockholder (including voting, dividend
and liquidation rights) with respect to the Purchased Shares, subject, however,
to the transfer restrictions of Articles B and C.

     B.   SECURITIES LAW COMPLIANCE
          -------------------------

          1.   RESTRICTED SECURITIES. The Purchased Shares have not been 
               ---------------------  
registered under the 1933 Act and are being issued to Optionee in reliance upon
the exemption from such registration provided by SEC Rule 701 for stock
issuances under compensatory benefit plans such as the Plan. Optionee hereby
confirms that Optionee has been informed that the Purchased Shares are
restricted securities under the 1933 Act and may not be resold or transferred
unless the Purchased Shares are first registered under the Federal securities
laws or unless an exemption from such registration is available. Accordingly,
Optionee hereby acknowledges that Optionee is prepared to hold the Purchased
Shares for an indefinite period and that Optionee is aware that SEC Rule 144
issued under the 1933 Act which exempts certain resales of unrestricted
securities is not 
<PAGE>
 
presently available to exempt the resale of the Purchased Shares from the
registration requirements of the 1933 Act.

     2.   RESTRICTIONS ON DISPOSITION OF PURCHASED SHARES.  Optionee shall make
          -----------------------------------------------                      
no disposition of the Purchased Shares (other than a Permitted Transfer) unless
and until there is compliance with all of the following requirements:

          (i)    Optionee shall have provided the Corporation with a written
     summary of the terms and conditions of the proposed disposition.

          (ii)   Optionee shall have complied with all requirements of this
     Agreement applicable to the disposition of the Purchased Shares.

          (iii)  Optionee shall have provided the Corporation with written
     assurances, in form and substance satisfactory to the Corporation, that (a)
     the proposed disposition does not require registration of the Purchased
     Shares under the 1933 Act or (b) all appropriate action necessary for
     compliance with the registration requirements of the 1933 Act or any
     exemption from registration available under the 1933 Act (including Rule
     144) has been taken.

          The Corporation shall not be required (i) to transfer on its books any
                                ---                                             
Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement or (ii) to treat as the owner of the Purchased
                             --                                            
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

          3.   RESTRICTIVE LEGENDS.  The stock certificates for the Purchased
               -------------------                                           
Shares shall be endorsed with the following restrictive legends:

               (i)  "The shares represented by this certificate have not been
     registered under the Securities Act of 1933. The shares may not be sold or
     offered for sale in the absence of (a) an effective registration statement
     for the shares under such Act, (b) a 'no action' letter of the Securities
     and Exchange Commission with respect to such sale or offer or (c)
     satisfactory assurances to the Corporation that registration under such Act
     is not required with respect to such sale or offer."

               (ii) "The shares represented by this certificate are unvested and
     are subject to certain repurchase rights and rights of first refusal
     granted to the Corporation and accordingly may not be sold, assigned,
     transferred, encumbered, or in any manner disposed of except in conformity
     with the terms of a written agreement dated ____________, 199__ between the
     Corporation and the registered holder of the shares (or the predecessor in
     interest to the shares). A copy of such agreement is maintained at the
     Corporation's principal corporate offices."

     C.   TRANSFER RESTRICTIONS
          ---------------------

          1.   RESTRICTION ON TRANSFER.  Except for any Permitted Transfer,
               -----------------------                                     
Optionee shall not transfer, assign, encumber or otherwise dispose of any of the
Purchased Shares which are subject to the Repurchase Right.  In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right or the Market Stand-Off.

          2.   TRANSFEREE OBLIGATIONS.  Each person (other than the Corporation)
               ----------------------                                           
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to (i) the Repurchase
Right, (ii) the First Refusal Right and (iii) the Market Stand-Off, to the same
extent such shares would be so subject if retained by Optionee.

          3.   MARKET STAND-OFF.
               ---------------- 

               (a)  In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Purchased Shares without the prior written consent of the
Corporation or its underwriters.  Such restriction (the "Market Stand-Off")
shall be in effect for such period of time from and after the effective date of
the final prospectus for the offering as may be requested by the Corporation or
such underwriters.  In no event, however, shall such period exceed one hundred
eighty (180) days and the Market Stand-Off shall in all events terminate two (2)
years after the effective date of the Corporation's initial public offering.

               (b)  Owner shall be subject to the Market Stand-Off provided and
                                                                   ------------
only if the officers and directors of the Corporation are also subject to
- -------
similar restrictions.

               (c)  Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

               (d)  In order to enforce the Market Stand-Off, the Corporation
may impose stop-transfer instructions with respect to the Purchased Shares until
the end of the applicable stand-off period.

     D.   REPURCHASE RIGHT
          ----------------

          1.   GRANT.  The Corporation is hereby granted the right (the
               -----                                                   
"Repurchase Right"), exercisable at any time during the ninety (90)-day period
following the date Optionee ceases for any reason to remain in Service or (if
later) during the ninety (90)-day period following the execution date of this
Agreement, to repurchase at the Exercise Price all or any portion of the
Purchased Shares in which Optionee is not, at the time of his or her cessation
of Service, vested in accordance with the Vesting Schedule (such shares to be
hereinafter referred to as the "Unvested Shares").

          2.   EXERCISE OF THE REPURCHASE RIGHT.  The Repurchase Right shall be
               --------------------------------                                
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the ninety (90)-day exercise period.  The notice
shall indicate the number of Unvested Shares to be repurchased and the date on
which the repurchase is to be effected, such date to be not more than thirty
(30) days after the date of such notice.  The certificates representing the
Unvested Shares to be repurchased shall be delivered to the Corporation prior to
the close of business on the date specified for the repurchase.  Concurrently
with the receipt of such stock certificates, the Corporation shall pay to Owner,
in cash or cash equivalents (including the cancellation of any purchase-money
indebtedness), an amount equal to the Exercise Price previously paid for the
Unvested Shares which are to be repurchased from Owner.

          3.   TERMINATION OF THE REPURCHASE RIGHT.  The Repurchase Right shall
               -----------------------------------                             
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2.  In addition, the Repurchase Right shall
terminate and cease to be exercisable with respect to any and all Purchased
Shares in which Optionee vests in accordance with the Vesting Schedule.  All
Purchased Shares as to which the Repurchase Right lapses shall, however, remain
subject to (i) the First Refusal Right and (ii) the Market Stand-Off.

          4.   AGGREGATE VESTING LIMITATION.  If the Option is exercised in more
               ----------------------------                                     
than one increment so that Optionee is a party to one or more other Stock
Purchase Agreements (the "Prior Purchase Agreements") which are executed prior
to the date of this Agreement, then the total number of Purchased Shares as to
which Optionee shall be deemed to have a fully-vested interest under this
Agreement and all Prior Purchase Agreements shall not exceed in the aggregate
the number of Purchased Shares in which Optionee would otherwise at the time be
vested, in accordance with the Vesting Schedule, had all the Purchased Shares
(including those acquired under the Prior Purchase Agreements) been acquired
exclusively under this Agreement.

          5.   RECAPITALIZATION.  Any new, substituted or additional securities
               ----------------                                                
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right, but only
to the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments to reflect such distribution shall be made to the number
and/or class of Purchased Shares subject to this Agreement and to the price per
share to be paid upon the exercise of the Repurchase Right in order to reflect
the effect of any such Recapitalization upon the Corporation's capital
structure; provided, however, that the aggregate purchase price shall remain the
           --------

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

               (a)  Immediately prior to the consummation of any Corporate
Transaction, the Repurchase Right shall automatically lapse in its entirety,
except to the extent the Repurchase Right is to be assigned to the successor
corporation (or parent thereof) in connection with the Corporate Transaction.

               (b)  To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to the new capital
stock or other property (including any cash payments) received in exchange for
the Purchased Shares in consummation of the Corporate Transaction, but only to
the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments shall be made to the price per share payable upon
exercise of the Repurchase Right to reflect the effect of the Corporate
Transaction upon the Corporation's capital structure; provided, however, that
the aggregate purchase price shall
                   --------                                                  
remain the same.

               (c)  The Repurchase Right shall automatically lapse in its
entirety, and all the Purchased Shares shall immediately vest in full, upon an
Involuntary Termination of Optionee's Service within eighteen (18) months
following the effective date of a Corporate Transaction in which the Repurchase
Right has been assigned.

Preferred Stock under the terms set forth in the Stockholders Agreement dated
February 2, 1996.

     F.   SPECIAL TAX ELECTION
          --------------------

          The acquisition of the Purchased Shares may result in adverse tax
consequences which may be avoided or mitigated by filing an election under Code
Section 83(b).  Such election must be filed within thirty (30) days after the
date of this Agreement.  A description of the tax consequences applicable to the
acquisition of the Purchased Shares and the form for making the Code Section
83(b) election are set forth in Exhibit II.  OPTIONEE SHOULD CONSULT WITH HIS OR
HER TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES OF ACQUIRING THE PURCHASED
SHARES AND THE ADVANTAGES AND DISADVANTAGES OF FILING THE CODE SECTION 83(B)
ELECTION.  OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE RESPONSIBILITY, AND
NOT THE CORPORATION'S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(B), EVEN
IF OPTIONEE REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS FILING
ON HIS OR HER BEHALF.

                      FEDERAL INCOME TAX CONSEQUENCES AND
                          SECTION 83(B) TAX ELECTION

     I.   FEDERAL INCOME TAX CONSEQUENCES AND SECTION 83(B) ELECTION FOR
          --------------------------------------------------------------
EXERCISE OF NON-STATUTORY OPTION.  If the Purchased Shares are acquired pursuant
- --------------------------------                                                
to the exercise of a Non-Statutory Option, as specified in the Grant Notice,
then under Code Section 83, the excess of the Fair Market Value of the Purchased
Shares on the date any forfeiture restrictions applicable to such shares lapse
over the Exercise Price paid for such shares will be reportable as ordinary
income on the lapse date.  For this purpose, the term "forfeiture restrictions"
includes the right of the Corporation to repurchase the Purchased Shares
pursuant to the Repurchase Right.  However, Optionee may elect under Code
Section 83(b) to be taxed at the time the Purchased Shares are acquired, rather
than when and as such Purchased Shares cease to be subject to such forfeiture
restrictions.  Such election must be filed with the Internal Revenue Service
within thirty (30) days after the date of the Agreement.  Even if the Fair
Market Value of the Purchased Shares on the date of the Agreement equals the
Exercise Price paid (and thus no tax is payable), the election must be made to
avoid adverse tax consequences in the future.  The form for making this election
is attached as part of this exhibit.  FAILURE TO MAKE THIS FILING WITHIN THE
APPLICABLE THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY
INCOME BY OPTIONEE AS THE FORFEITURE RESTRICTIONS LAPSE.

     II.  FEDERAL INCOME TAX CONSEQUENCES AND CONDITIONAL SECTION 83(B) ELECTION
          ----------------------------------------------------------------------
FOR EXERCISE OF INCENTIVE OPTION.  If the Purchased Shares are acquired pursuant
- --------------------------------                                                
to the exercise of an Incentive Option, as specified in the Grant Notice, then
the following tax principles shall be applicable to the Purchased Shares:

               (i)    For regular tax purposes, no taxable income will be
     recognized at the time the Option is exercised.

               (ii)   The excess of (a) the Fair Market Value of the Purchased
     Shares on the date the Option is exercised or (if later) on the date any
     forfeiture restrictions applicable to the Purchased Shares lapse over (b)
     the Exercise Price paid for the Purchased Shares will be includible in
     Optionee's taxable income for alternative minimum tax purposes.

               (iii)  If Optionee makes a disqualifying disposition of the
     Purchased Shares, then Optionee will recognize ordinary income in the year
     of such disposition equal in amount to the excess of (a) the Fair Market
     Value of the Purchased Shares on the date the Option is exercised or (if
     later) on the date any forfeiture restrictions applicable to the Purchased
     Shares lapse over (b) the Exercise Price paid for the Purchased Shares. Any
     additional gain recognized upon the disqualifying disposition will be
     either short-term or long-term capital gain depending upon the period for
     which the Purchased Shares are held prior to the

                                     II-1.
<PAGE>
 
     disposition.

          (iv) For purposes of the foregoing, the term "forfeiture restrictions"
     will include the right of the Corporation to repurchase the Purchased
     Shares pursuant to the Repurchase Right. The term "disqualifying
     disposition" means any sale or other disposition /1/ of the Purchased
                                                       -
     Shares within two (2) years after the Grant Date or within one (1) year
     after the exercise date of the Option.


          (v)  In the absence of final Treasury Regulations relating to
     Incentive Options, it is not certain whether Optionee may, in connection
     with the exercise of the Option for any Purchased Shares at the time
     subject to forfeiture restrictions, file a protective election under Code
     Section 83(b) which would limit (a) Optionee's alternative minimum taxable
     income upon exercise and (b) Optionee's ordinary income upon a
     disqualifying disposition to the excess of the Fair Market Value of the
     Purchased Shares on the date the Option is exercised over the Exercise
     Price paid for the Purchased Shares. Accordingly, such election if properly
     filed will only be allowed to the extent the final Treasury Regulations
     permit such a protective election. Page 2 of the attached form for making
     the election should be filed with any election made in connection with the
     exercise of an Incentive Option.









__________________________
/1/  Generally, a disposition of shares purchased under an Incentive Option
 -
includes any transfer of legal title, including a transfer by sale, exchange or
gift, but does not include a transfer to the Optionee's spouse, a transfer into
joint ownership with right of survivorship if Optionee remains one of the joint
owners, a pledge, a transfer by bequest or inheritance or certain tax free
exchanges permitted under the Code.

                            SECTION 83(B) ELECTION

          This statement is being made under Section 83(b) of the Internal
Revenue Code, pursuant to Treas. Reg. Section 1.83-2.

(1)  The taxpayer who performed the services is:

     Name:
     Address:
     Taxpayer Ident. No.:

(2)  The property with respect to which the election is being made is
     ____________ shares of the common stock of Vignette Corporation

(3)  The property was issued on _____________, 199__.

(4)  The taxable year in which the election is being made is the calendar year
     199__.

(5)  The property is subject to a repurchase right pursuant to which the issuer
     has the right to acquire the property at the original purchase price if for
     any reason taxpayer's employment with the issuer is terminated.  The
     issuer's repurchase right lapses in a series of installments over a forty-
     eight (48) month period ending on _____________, 20__.

(6)  The fair market value at the time of transfer (determined without regard to
     any restriction other than a restriction which by its terms will never
     lapse) is $_____________per share.

(7)  The amount paid for such property is $____________ per share.

(8)  A copy of this statement was furnished to Vignette Corporation for whom
     taxpayer rendered the services underlying the transfer of property.

(9)   This statement is executed on _______________________, 199__.


_________________________      _________________________________________________
Spouse (if any)          Taxpayer

This election must be filed with the Internal Revenue Service Center with which
taxpayer files his or her Federal income tax returns and must be made within
thirty (30) days after the execution date of the Stock Purchase Agreement.  This
filing should be made by registered or certified mail, return receipt requested.
Optionee must retain two (2) copies of the completed form for filing with his or
her Federal and state tax returns for the current tax year and an additional
copy for his or her records.
<PAGE>
 
The property described in the above Section 83(b) election is comprised of
shares of common stock acquired pursuant to the exercise of an incentive stock
option under Section 422 of the Internal Revenue Code (the "Code").
Accordingly, it is the intent of the Taxpayer to utilize this election to
achieve the following tax results:

          1.   The purpose of this election is to have the alternative minimum
taxable income attributable to the purchased shares measured by the amount by
which the fair market value of such shares at the time of their transfer to the
Taxpayer exceeds the purchase price paid for the shares.  In the absence of this
election, such alternative minimum taxable income would be measured by the
spread between the fair market value of the purchased shares and the purchase
price which exists on the various lapse dates in effect for the forfeiture
restrictions applicable to such shares.  The election is to be effective to the
full extent permitted under the Code.

          2.   Section 421(a)(1) of the Code expressly excludes from income any
excess of the fair market value of the purchased shares over the amount paid for
such shares.  Accordingly, this election is also intended to be effective in the
event there is a "disqualifying disposition" of the shares, within the meaning
of Section 421(b) of the Code, which would otherwise render the provisions of
Section 83(a) of the Code applicable at that time.  Consequently, the Taxpayer
hereby elects to have the amount of disqualifying disposition income measured by
the excess of the fair market value of the purchased shares on the date of
transfer to the Taxpayer over the amount paid for such shares.  Since Section
421(a) presently applies to the shares which are the subject of this Section
83(b) election, no taxable income is actually recognized for regular tax
purposes at this time, and no income taxes are payable, by the Taxpayer as a
result of this election.


THIS PAGE 2 IS TO BE ATTACHED TO ANY SECTION 83(B) ELECTION FILED IN CONNECTION
WITH THE EXERCISE OF AN INCENTIVE STOCK OPTION UNDER THE FEDERAL TAX LAWS.

                          1998 Equity Incentive Plan
                                        

     ARTICLE 1.  INTRODUCTION.

          The Plan was adopted by the Board to be effective as of the date of
the IPO.  The purpose of the Plan is to promote the long-term success of the
Corporation and the creation of stockholder value by (a) encouraging Employees,
Outside Directors and Consultants to focus on critical long-range objectives,
(b) encouraging the attraction and retention of Employees, Outside Directors and
Consultants with exceptional qualifications and (c) linking Employees, Outside
Directors and Consultants directly to stockholder interests through increased
stock ownership.  The Plan seeks to achieve this purpose by providing for Awards
in the form of Restricted Shares, Stock Units, Options (which may constitute
incentive stock options or nonstatutory stock options) or stock appreciation
rights.

          The Plan shall be governed by, and construed in accordance with, the
laws of the State of Delaware (except their choice-of-law provisions).

     ARTICLE 2.  ADMINISTRATION.

     2.1  Committee Composition.  The Plan shall be administered by the
Committee.  The Committee shall consist exclusively of two or more directors of
the Corporation, who shall be appointed by the Board.  In addition, the
composition of the Committee shall satisfy:

          (a)  Such requirements as the Securities and Exchange Commission may
     establish for administrators acting under plans intended to qualify for
     exemption under Rule 16b-3 (or its successor) under the Exchange Act; and

          (b)  Such requirements as the Internal Revenue Service may establish
     for outside directors acting under plans intended to qualify for exemption
     under Section 162(m)(4)(C) of the Code.

     2.2  Committee Responsibilities.  The Committee shall (a) select the
Employees, Outside Directors and Consultants who are to receive Awards under the
Plan, (b) determine the type, number, vesting requirements and other features
and conditions of such Awards, (c) interpret the Plan and (d) make all other
decisions relating to the operation of the Plan.  The Committee may adopt such
rules or guidelines as it deems appropriate to implement the Plan.  The
Committee's determinations under the Plan shall be final and binding on all
persons.

     2.3  Committee for Non-Officer Grants.  The Board may also appoint a
secondary committee of the Board, which shall be composed of one or more
directors of the Corporation who need not satisfy the requirements of Section
2.1.  Such secondary committee may administer the Plan with respect to Employees
and Consultants who are not considered officers or directors 
<PAGE>
 
of the Corporation under Section 16 of the Exchange Act, may grant Awards under
the Plan to such Employees and Consultants and may determine all features and
conditions of such Awards. Within the limitations of this Section 2.3, any
reference in the Plan to the Committee shall include such secondary committee.

     ARTICLE 3.  SHARES AVAILABLE FOR GRANTS.

     3.1  Basic Limitation.  Shares of Common Stock issued pursuant to the Plan
may be authorized but unissued shares or treasury shares.  The aggregate number
of Options, SARs, Stock Units and Restricted Shares awarded under the Plan shall
not exceed (a) [_________], plus shares remaining available for issuance under
the Predecessor Plan, plus (b) the additional shares of Common Stock described
in Sections 3.2 and 3.3.  The limitation of this Section 3.1 shall be subject to
adjustment pursuant to Article 11.

     3.2  Annual Increase in Shares.  As of January 1 of each year, commencing
with the year 1999 and ending with the year 2002, the aggregate number of
Options, SARs, Stock Units and Restricted Shares that may be awarded under the
Plan shall automatically increase by a number equal to the lesser of (a) 5% of
the total number of shares of Common Stock then outstanding or (b) 1,000,000
shares.

     3.3  Additional Shares.  If Restricted Shares or shares of Common Stock
issued upon the exercise of Options are forfeited (including any options
incorporated from the Predecessor Plan), then such shares of Common Stock shall
again become available for Awards under the Plan.  If Stock Units, Options or
SARs are forfeited or terminate for any other reason before being exercised,
then the corresponding shares of Common Stock shall again become available for
Awards under the Plan.  If Stock Units are settled, then only the number of
shares of Common Stock (if any) actually issued in settlement of such Stock
Units shall reduce the number available under Section 3.1 and the balance shall
again become available for Awards under the Plan.  If SARs are exercised, then
only the number of shares of Common Stock (if any) actually issued in settlement
of such SARs shall reduce the number available under Section 3.1 and the balance
shall again become available for Awards under the Plan.  The foregoing
notwithstanding, the aggregate number of shares of Common Stock that may be
issued under the Plan upon the exercise of ISOs shall not be increased when
Restricted Shares or other shares of Common Stock are forfeited.

     3.4  Dividend Equivalents.  Any dividend equivalents paid or credited under
the Plan shall not be applied against the number of Restricted Shares, Stock
Units, Options or SARs available for Awards, whether or not such dividend
equivalents are converted into Stock Units.

     ARTICLE 4.  ELIGIBILITY.

     4.1  Incentive Stock Options.  Only Employees who are common-law employees
of the Corporation, a Parent or a Subsidiary shall be eligible for the grant of
ISOs.  In addition, an Employee who owns more than 10% of the total combined
voting power of all classes of outstanding stock of the Corporation or any of
its Parents or Subsidiaries shall not be eligible for 

                                       2
<PAGE>
 
the grant of an ISO unless the requirements set forth in Section 422(c)(6) of
the Code are satisfied.

     4.2  Other Grants.  Only Employees, Outside Directors and Consultants shall
be eligible for the grant of Restricted Shares, Stock Units, NSOs or SARs.

     ARTICLE 5.  OPTIONS.

     5.1  Stock Option Agreement.  Each grant of an Option under the Plan shall
be evidenced by a Stock Option Agreement between the Optionee and the
Corporation.  Such Option shall be subject to all applicable terms of the Plan
and may be subject to any other terms that are not inconsistent with the Plan.
The Stock Option Agreement shall specify whether the Option is an ISO or an NSO.
The provisions of the various Stock Option Agreements entered into under the
Plan need not be identical.  Options may be granted in consideration of a
reduction in the Optionee's other compensation.  A Stock Option Agreement may
provide that a new Option will be granted automatically to the Optionee when he
or she exercises a prior Option and pays the Exercise Price in the form
described in Section 6.2.

     5.2  Number of Shares.  Each Stock Option Agreement shall specify the
number of shares of Common Stock subject to the Option and shall provide for the
adjustment of such number in accordance with Article 11.  Options granted to any
Optionee in a single fiscal year of the Corporation shall not cover more than
1,000,000 shares [post-split] of Common Stock, except that Options granted to a
new Employee in the fiscal year of the Corporation in which his or her service
as an Employee first commences shall not cover more than 1,250,000 shares [post-
split] of Common Stock.  The limitations set forth in the preceding sentence
shall be subject to adjustment in accordance with Article 11.

     5.3  Exercise Price.  Each Stock Option Agreement shall specify the
Exercise Price; provided that the Exercise Price under an ISO shall in no event
be less than 100% of the Fair Market Value of a share of Common Stock on the
date of grant and the Exercise Price under an NSO shall in no event be less than
85% of the Fair Market Value of a share of Common Stock on the date of grant.
In the case of an NSO, a Stock Option Agreement may specify an Exercise Price
that varies in accordance with a predetermined formula while the NSO is
outstanding.

     5.4  Exercisability and Term.  Each Stock Option Agreement shall specify
the date or event when all or any installment of the Option is to become
exercisable.  The Stock Option Agreement shall also specify the term of the
Option; provided that the term of an ISO shall in no event exceed 10 years from
the date of grant.  A Stock Option Agreement may provide for accelerated
exercisability in the event of the Optionee's death, disability or retirement or
other events and may provide for expiration prior to the end of its term in the
event of the termination of the Optionee's service.  Options may be awarded in
combination with SARs, and such an Award may provide that the Options will not
be exercisable unless the related SARs are forfeited.

     5.5  Modification or Assumption of Options.  Within the limitations of the
Plan, the Committee may modify, extend or assume outstanding options or may
accept the cancellation of 

                                       3
<PAGE>
 
outstanding options (whether granted by the Corporation or by another issuer) in
return for the grant of new options for the same or a different number of shares
and at the same or a different exercise price. The foregoing notwithstanding, no
modification of an Option shall, without the consent of the Optionee, alter or
impair his or her rights or obligations under such Option.

     5.6  Buyout Provisions.  The Committee may at any time (a) offer to buy out
for a payment in cash or cash equivalents an Option previously granted or (b)
authorize an Optionee to elect to cash out an Option previously granted, in
either case at such time and based upon such terms and conditions as the
Committee shall establish.

ARTICLE 6.  PAYMENT FOR OPTION SHARES.

     6.1  General Rule.  The entire Exercise Price of shares of Common Stock
issued upon exercise of Options shall be payable in cash or cash equivalents at
the time when such shares of Common Stock are purchased, except as follows:

          (a)  In the case of an ISO granted under the Plan, payment shall be
     made only pursuant to the express provisions of the applicable Stock Option
     Agreement. The Stock Option Agreement may specify that payment may be made
     in any form(s) described in this Article 6.

          (b)  In the case of an NSO, the Committee may at any time accept
     payment in any form(s) described in this Article 6.

     6.2  Surrender of Common Stock.  To the extent that this Section 6.2 is
applicable, all or any part of the Exercise Price may be paid by surrendering,
or attesting to the ownership of, shares of Common Stock that are already owned
by the Optionee.  Such shares of Common Stock shall be valued at their Fair
Market Value on the date when the new shares of Common Stock are purchased under
the Plan.  The Optionee shall not surrender, or attest to the ownership of,
shares of Common Stock in payment of the Exercise Price if such action would
cause the Corporation to recognize compensation expense (or additional
compensation expense) with respect to the Option for financial reporting
purposes.

     6.3  Exercise/Sale.  To the extent that this Section 6.3 is applicable, all
or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the Corporation) an irrevocable direction to
a securities broker approved by the Corporation to sell all or part of the
shares of Common Stock being purchased under the Plan and to deliver all or part
of the sales proceeds to the Corporation.

     6.4  Exercise/Pledge.  To the extent that this Section 6.4 is applicable,
all or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the Corporation) an irrevocable direction to
pledge all or part of the shares of Common Stock being purchased under the Plan
to a securities broker or lender approved by the Corporation, as security for a
loan, and to deliver all or part of the loan proceeds to the Corporation.

                                       4
<PAGE>
 
     6.5  Promissory Note.  To the extent that this Section 6.5 is applicable,
all or any part of the Exercise Price and any withholding taxes may be paid by
delivering (on a form prescribed by the Corporation) a full-recourse promissory
note.  However, the par value of the shares of Common Stock being purchased
under the Plan, if newly issued, shall be paid in cash or cash equivalents.

     6.6  Other Forms of Payment.  To the extent that this Section 6.6 is
applicable, all or any part of the Exercise Price and any withholding taxes may
be paid in any other form that is consistent with applicable laws, regulations
and rules.

     ARTICLE 7.  STOCK APPRECIATION RIGHTS.

     7.1  SAR Agreement.  Each grant of a SAR under the Plan shall be evidenced
by an SAR Agreement between the Optionee and the Corporation.  Such SAR shall be
subject to all applicable terms of the Plan and may be subject to any other
terms that are not inconsistent with the Plan.  The provisions of the various
SAR Agreements entered into under the Plan need not be identical.  SARs may be
granted in consideration of a reduction in the Optionee's other compensation.

     7.2  Number of Shares.  Each SAR Agreement shall specify the number of
shares of Common Stock to which the SAR pertains and shall provide for the
adjustment of such number in accordance with Article 11.  SARs granted to any
Optionee in a single calendar year shall in no event pertain to more than
1,000,000 shares [post-split] of Common Stock, except that SARs granted to a new
Employee in the fiscal year of the Corporation in which his or her service as an
Employee first commences shall not pertain to more than 1,250,000 shares [post-
split] of Common Stock.  The limitations set forth in the preceding sentence
shall be subject to adjustment in accordance with Article 11.

     7.3  Exercise Price.  Each SAR Agreement shall specify the Exercise Price.
A SAR Agreement may specify an Exercise Price that varies in accordance with a
predetermined formula while the SAR is outstanding.

     7.4  Exercisability and Term.  Each SAR Agreement shall specify the date
when all or any installment of the SAR is to become exercisable.  The SAR
Agreement shall also specify the term of the SAR.  An SAR Agreement may provide
for accelerated exercisability in the event of the Optionee's death, disability
or retirement or other events and may provide for expiration prior to the end of
its term in the event of the termination of the Optionee's service.  SARs may be
awarded in combination with Options, and such an Award may provide that the SARs
will not be exercisable unless the related Options are forfeited.  An SAR may be
included in an ISO only at the time of grant but may be included in an NSO at
the time of grant or thereafter.  A SAR granted under the Plan may provide that
it will be exercisable only in the event of a Change in Control.

     7.5  Exercise of SARs.  Upon exercise of a SAR, the Optionee (or any person
having the right to exercise the SAR after his or her death) shall receive from
the Corporation (a) shares of Common Stock, (b) cash or (c) a combination of
shares of Common Stock and cash, as the 

                                       5
<PAGE>
 
Committee shall determine. The amount of cash and/or the Fair Market Value of
shares of Common Stock received upon exercise of SARs shall, in the aggregate,
be equal to the amount by which the Fair Market Value (on the date of surrender)
of the shares of Common Stock subject to the SARs exceeds the Exercise Price.
If, on the date when an SAR expires, the Exercise Price under such SAR is less
than the Fair Market Value on such date but any portion of such SAR has not been
exercised or surrendered, then such SAR shall automatically be deemed to be
exercised as of such date with respect to such portion.

     7.6  Modification or Assumption of SARs.  Within the limitations of the
Plan, the Committee may modify, extend or assume outstanding SARs or may accept
the cancellation of outstanding SARs (whether granted by the Corporation or by
another issuer) in return for the grant of new SARs for the same or a different
number of shares and at the same or a different exercise price.  The foregoing
notwithstanding, no modification of an SAR shall, without the consent of the
Optionee, alter or impair his or her rights or obligations under such SAR.

     ARTICLE 8.  RESTRICTED SHARES.

     8.1  Restricted Stock Agreement.  Each grant of Restricted Shares under the
Plan shall be evidenced by a Restricted Stock Agreement between the recipient
and the Corporation.  Such Restricted Shares shall be subject to all applicable
terms of the Plan and may be subject to any other terms that are not
inconsistent with the Plan.  The provisions of the various Restricted Stock
Agreements entered into under the Plan need not be identical.

     8.2  Payment for Awards.  Subject to the following sentence, Restricted
Shares may be sold or awarded under the Plan for such consideration as the
Committee may determine, including (without limitation) cash, cash equivalents,
full-recourse promissory notes, past services and future services.  To the
extent that an Award consists of newly issued Restricted Shares, the Award
recipient shall furnish consideration with a value not less than the par value
of such Restricted Shares in the form of cash, cash equivalents or past services
rendered to the Corporation (or a Parent or Subsidiary), as the Committee may
determine.

     8.3  Vesting Conditions.  Each award of Restricted Shares may or may not be
subject to vesting.  Vesting shall occur, in full or in installments, upon
satisfaction of the conditions specified in the Restricted Stock Agreement.  A
Restricted Stock Agreement may provide for accelerated vesting in the event of
the Participant's death, disability or retirement or other events.

     8.4  Voting and Dividend Rights.  The holders of Restricted Shares awarded
under the Plan shall have the same voting, dividend and other rights as the
Corporation's other stockholders.  A Restricted Stock Agreement, however, may
require that the holders of Restricted Shares invest any cash dividends received
in additional Restricted Shares.  Such additional Restricted Shares shall be
subject to the same conditions and restrictions as the Award with respect to
which the dividends were paid.

                                       6
<PAGE>
 
     ARTICLE 9.  STOCK UNITS.

     9.1  Stock Unit Agreement.  Each grant of Stock Units under the Plan shall
be evidenced by a Stock Unit Agreement between the recipient and the
Corporation.  Such Stock Units shall be subject to all applicable terms of the
Plan and may be subject to any other terms that are not inconsistent with the
Plan.  The provisions of the various Stock Unit Agreements entered into under
the Plan need not be identical.  Stock Units may be granted in consideration of
a reduction in the recipient's other compensation.

     9.2  Payment for Awards.  To the extent that an Award is granted in the
form of Stock Units, no cash consideration shall be required of the Award
recipients.

     9.3  Vesting Conditions.  Each Award of Stock Units may or may not be
subject to vesting.  Vesting shall occur, in full or in installments, upon
satisfaction of the conditions specified in the Stock Unit Agreement.  A Stock
Unit Agreement may provide for accelerated vesting in the event of the
Participant's death, disability or retirement or other events.

     9.4  Voting and Dividend Rights.  The holders of Stock Units shall have no
voting rights.  Prior to settlement or forfeiture, any Stock Unit awarded under
the Plan may, at the Committee's discretion, carry with it a right to dividend
equivalents.  Such right entitles the holder to be credited with an amount equal
to all cash dividends paid on one share of Common Stock while the Stock Unit is
outstanding.  Dividend equivalents may be converted into additional Stock Units.
Settlement of dividend equivalents may be made in the form of cash, in the form
of shares of Common Stock, or in a combination of both.  Prior to distribution,
any dividend equivalents which are not paid shall be subject to the same
conditions and restrictions as the Stock Units to which they attach.

     9.5  Form and Time of Settlement of Stock Units.  Settlement of vested
Stock Units may be made in the form of (a) cash, (b) shares of Common Stock or
(c) any combination of both, as determined by the Committee.  The actual number
of Stock Units eligible for settlement may be larger or smaller than the number
included in the original Award, based on predetermined performance factors.
Methods of converting Stock Units into cash may include (without limitation) a
method based on the average Fair Market Value of shares of Common Stock over a
series of trading days.  Vested Stock Units may be settled in a lump sum or in
installments.  The distribution may occur or commence when all vesting
conditions applicable to the Stock Units have been satisfied or have lapsed, or
it may be deferred to any later date.  The amount of a deferred distribution may
be increased by an interest factor or by dividend equivalents.  Until an Award
of Stock Units is settled, the number of such Stock Units shall be subject to
adjustment pursuant to Article 11.

     9.6  Death of Recipient.  Any Stock Unit Award that becomes payable after
the recipient's death shall be distributed to the recipient's beneficiary or
beneficiaries.  Each recipient of a Stock Unit Award under the Plan shall
designate one or more beneficiaries for this purpose by filing the prescribed
form with the Corporation.  A beneficiary designation may be changed by filing
the prescribed form with the Corporation at any time before the Award
recipient's death.  If no beneficiary was designated or if no designated
beneficiary survives the 

                                       7
<PAGE>
 
Award recipient, then any Stock Unit Award that becomes payable after the
recipient's death shall be distributed to the recipient's estate.

     9.7   Creditors' Rights. A holder of Stock Units shall have no rights other
than those of a general creditor of the Corporation. Stock Units represent an
unfunded and unsecured obligation of the Corporation, subject to the terms and
conditions of the applicable Stock Unit Agreement.

     ARTICLE 10.  CHANGE IN CONTROL

     10.1  Effect of Change in Control.  In the event of any Change in Control,
each outstanding Award shall automatically accelerate so that each such Award
shall, immediately prior to the effective date of the Change in Control, become
fully exercisable for all of the shares of Common Stock at the time subject to
such Award and may be exercised for any or all of those shares as fully-vested
shares of Common Stock.  However, an outstanding Award shall not so accelerate
if and to the extent such Award is, in connection with the Change in Control,
either to be assumed by the successor corporation (or parent thereof) or to be
replaced with a comparable Award for shares of the capital stock of the
successor corporation (or parent thereof).  The determination of Award
comparability shall be made by the Plan Administrator, and its determination
shall be final, binding and conclusive.

     10.2  Involuntary Termination.  In addition, in the event that the Award is
assumed by the successor corporation (or parent thereof) and the Participant
experiences an Involuntary Termination within eighteen months following a Change
in Control, each outstanding Award shall automatically accelerate so that each
such Award shall, immediately prior to the effective date of the Involuntary
Termination, become fully exercisable for all of the shares of Common Stock at
the time subject to such Award and may be exercised for any or all of those
shares as fully-vested shares of Common Stock.

     ARTICLE 11.  PROTECTION AGAINST DILUTION.

     11.1  Adjustments.  In the event of a subdivision of the outstanding shares
of Common Stock, a declaration of a dividend payable in shares of Common Stock,
a declaration of a dividend payable in a form other than shares of Common Stock
in an amount that has a material effect on the price of shares of Common Stock,
a combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise) into a lesser number of shares of Common Stock, a
recapitalization, a spin-off or a similar occurrence, the Committee shall make
such adjustments as it, in its sole discretion, deems appropriate in one or more
of:

           (a)  The number of Options, SARs, Restricted Shares and Stock Units
     available for future Awards under Article 3;

           (b)  The limitations set forth in Sections 5.2 and 8.2;

           (c)  The number of shares of Common Stock covered by each outstanding
     Option and SAR;

                                       8
<PAGE>
 
           (d)  The Exercise Price under each outstanding Option and SAR; or

           (e)  The number of Stock Units included in any prior Award which has
     not yet been settled.

Except as provided in this Article 11, a Participant shall have no rights by
reason of any issue by the Corporation of stock of any class or securities
convertible into stock of any class, any subdivision or consolidation of shares
of stock of any class, the payment of any stock dividend or any other increase
or decrease in the number of shares of stock of any class.

     11.2  Dissolution or Liquidation. To the extent not previously exercised or
settled, Options, SARs and Stock Units shall terminate immediately prior to the
dissolution or liquidation of the Corporation.

     11.3  Reorganizations.  In the event that the Corporation is a party to a
merger or other reorganization, outstanding Awards shall be subject to the
agreement of merger or reorganization.  Such agreement shall provide for (a) the
continuation of the outstanding Awards by the Corporation, if the Corporation is
a surviving corporation, (b) the assumption of the outstanding Awards by the
surviving corporation or its parent or subsidiary, (c) the substitution by the
surviving corporation or its parent or subsidiary of its own awards for the
outstanding Awards, (d) full exercisability or vesting and accelerated
expiration of the outstanding Awards or (e) settlement of the full value of the
outstanding Awards in cash or cash equivalents followed by cancellation of such
Awards.

     ARTICLE 12.  DEFERRAL OF AWARDS.

           The Committee (in its sole discretion) may permit or require a
Participant to:

           (a)  Have cash that otherwise would be paid to such Participant as a
     result of the exercise of an SAR or the settlement of Stock Units credited
     to a deferred compensation account established for such Participant by the
     Committee as an entry on the Corporation's books;

           (b)  Have shares of Common Stock that otherwise would be delivered to
     such Participant as a result of the exercise of an Option or SAR converted
     into an equal number of Stock Units; or

           (c)  Have shares of Common Stock that otherwise would be delivered to
     such Participant as a result of the exercise of an Option or SAR or the
     settlement of Stock Units converted into amounts credited to a deferred
     compensation account established for such Participant by the Committee as
     an entry on the Corporation's books. Such amounts shall be determined by
     reference to the Fair Market Value of such shares of Common Stock as of the
     date when they otherwise would have been delivered to such Participant.

                                       9
<PAGE>
 
A deferred compensation account established under this Article 12 may be
credited with interest or other forms of investment return, as determined by the
Committee.  A Participant for whom such an account is established shall have no
rights other than those of a general creditor of the Corporation.  Such an
account shall represent an unfunded and unsecured obligation of the Corporation
and shall be subject to the terms and conditions of the applicable agreement
between such Participant and the Corporation.  If the deferral or conversion of
Awards is permitted or required, the Committee (in its sole discretion) may
establish rules, procedures and forms pertaining to such Awards, including
(without limitation) the settlement of deferred compensation accounts
established under this Article 12.

     ARTICLE 13.  AWARDS UNDER OTHER PLANS.

           The Corporation may grant awards under other plans or programs.  Such
awards may be settled in the form of shares of Common Stock issued under this
Plan.  Such shares of Common Stock shall be treated for all purposes under the
Plan like shares of Common Stock issued in settlement of Stock Units and shall,
when issued, reduce the number of shares of Common Stock available under 
Article 3.

     ARTICLE 14.  PAYMENT OF DIRECTOR'S FEES IN SECURITIES.

     14.1  Effective Date.  No provision of this Article 14 shall be effective
unless and until the Board has determined to implement such provision.

     14.2  Elections to Receive NSOs, Restricted Shares or Stock Units.  An
Outside Director may elect to receive his or her annual retainer payments and/or
meeting fees from the Corporation in the form of cash, NSOs, Restricted Shares
or Stock Units, or a combination thereof, as determined by the Board.  Such
NSOs, Restricted Shares and Stock Units shall be issued under the Plan.  An
election under this Article 14 shall be filed with the Corporation on the
prescribed form.

     14.3  Number and Terms of NSOs, Restricted Shares or Stock Units.  The
number of NSOs, Restricted Shares or Stock Units to be granted to Outside
Directors in lieu of annual retainers and meeting fees that would otherwise be
paid in cash shall be calculated in a manner determined by the Board.  The terms
of such NSOs, Restricted Shares or Stock Units shall also be determined by the
Board.

     ARTICLE 15.  LIMITATION ON RIGHTS.

     15.1  Retention Rights.  Neither the Plan nor any Award granted under the
Plan shall be deemed to give any individual a right to remain an Employee,
Outside Director or Consultant.  The Corporation and its Parents, Subsidiaries
and Affiliates reserve the right to terminate the service of any Employee,
Outside Director or Consultant at any time, with or without cause, subject to
applicable laws, the Corporation's certificate of incorporation and by-laws and
a written employment agreement (if any).

                                      10
<PAGE>
 
     15.2  Stockholders' Rights.  A Participant shall have no dividend rights,
voting rights or other rights as a stockholder with respect to any shares of
Common Stock covered by his or her Award prior to the time when a stock
certificate for such shares of Common Stock is issued or, if applicable, the
time when he or she becomes entitled to receive such shares of Common Stock by
filing any required notice of exercise and paying any required Exercise Price.
No adjustment shall be made for cash dividends or other rights for which the
record date is prior to such time, except as expressly provided in the Plan.

     15.3  Regulatory Requirements.  Any other provision of the Plan
notwithstanding, the obligation of the Corporation to issue shares of Common
Stock under the Plan shall be subject to all applicable laws, rules and
regulations and such approval by any regulatory body as may be required.  The
Corporation reserves the right to restrict, in whole or in part, the delivery of
shares of Common Stock pursuant to any Award prior to the satisfaction of all
legal requirements relating to the issuance of such shares of Common Stock, to
their registration, qualification or listing or to an exemption from
registration, qualification or listing.

     ARTICLE 16.  WITHHOLDING TAXES.

     16.1  General.  To the extent required by applicable federal, state, local
or foreign law, a Participant or his or her successor shall make arrangements
satisfactory to the Corporation for the satisfaction of any withholding tax
obligations that arise in connection with the Plan.  The Corporation shall not
be required to issue any shares of Common Stock or make any cash payment under
the Plan until such obligations are satisfied.

     16.2  Share Withholding.  The Committee may permit a Participant to satisfy
all or part of his or her withholding or income tax obligations by having the
Corporation withhold all or a portion of any shares of Common Stock that
otherwise would be issued to him or her or by surrendering all or a portion of
any shares of Common Stock that he or she previously acquired.  Such shares of
Common Stock shall be valued at their Fair Market Value on the date when taxes
otherwise would be withheld in cash.

     ARTICLE 17.  FUTURE OF THE PLAN.

     17.1  Term of the Plan.  The Plan, as set forth herein, shall become
effective as of the date of the IPO.  The Plan shall remain in effect until it
is terminated under Section 17.2, except that no ISOs shall be granted on or
after the 10/th/ anniversary of the later of (a) the date when the Board adopted
the Plan or (b) the date when the Board adopted the most recent increase in the
number of shares of Common Stock available under Article 3 which was approved by
the Corporation's stockholders.

     17.2  Amendment or Termination.  The Board may, at any time and for any
reason, amend or terminate the Plan.  An amendment of the Plan shall be subject
to the approval of the Corporation's stockholders only to the extent required by
applicable laws, regulations or rules.  No Awards shall be granted under the
Plan after the termination thereof.  The termination of the Plan, or any
amendment thereof, shall not affect any Award previously granted under the Plan.

<PAGE>
 
     ARTICLE 18.  LIMITATION ON PAYMENTS.

     18.1  Scope of Limitation. This Article 18 shall apply to an Award only if:

           (a)  The independent auditors most recently selected by the Board
     (the "Auditors") determine that the after-tax value of such Award to the
     Participant, taking into account the effect of all federal, state and local
     income taxes, employment taxes and excise taxes applicable to the
     Participant (including the excise tax under Section 4999 of the Code), will
     be greater after the application of this Article 18 than it was before the
     application of this Article 18; or

           (b)  The Committee, at the time of making an Award under the Plan or
     at any time thereafter, specifies in writing that such Award shall be
     subject to this Article 18 (regardless of the after-tax value of such Award
     to the Participant).

If this Article 18 applies to an Award, it shall supersede any contrary
provision of the Plan or of any Award granted under the Plan.

     18.2  Basic Rule. In the event that the Auditors determine that any payment
or transfer by the Corporation under the Plan to or for the benefit of a
Participant (a "Payment") would be nondeductible by the Corporation for federal
income tax purposes because of the provisions concerning "excess parachute
payments" in Section 280G of the Code, then the aggregate present value of all
Payments shall be reduced (but not below zero) to the Reduced Amount. For
purposes of this Article 18, the "Reduced Amount" shall be the amount, expressed
as a present value, which maximizes the aggregate present value of the Payments
without causing any Payment to be nondeductible by the Corporation because of
Section 280G of the Code.

     18.3  Reduction of Payments.  If the Auditors determine that any Payment
would be nondeductible by the Corporation because of Section 280G of the Code,
then the Corporation shall promptly give the Participant notice to that effect
and a copy of the detailed calculation thereof and of the Reduced Amount, and
the Participant may then elect, in his or her sole discretion, which and how
much of the Payments shall be eliminated or reduced (as long as after such
election the aggregate present value of the Payments equals the Reduced Amount)
and shall advise the Corporation in writing of his or her election within 10
days of receipt of notice.  If no such election is made by the Participant
within such 10-day period, then the Corporation may elect which and how much of
the Payments shall be eliminated or reduced (as long as after such election the
aggregate present value of the Payments equals the Reduced Amount) and shall
notify the Participant promptly of such election.  For purposes of this Article
18, present value shall be determined in accordance with Section 280G(d)(4) of
the Code.  All determinations made by the Auditors under this Article 18 shall
be binding upon the Corporation and the Participant and shall be made within 60
days of the date when a Payment becomes payable or transferable.  As promptly as
practicable following such determination and the elections hereunder, the
Corporation shall pay or transfer to or for the benefit of the Participant such
amounts as are then due to him or her under the Plan and shall promptly pay or
transfer to or for the benefit of the Participant in the future such amounts as
become due to him or her under the Plan.

                                      12
<PAGE>
 
     18.4  Overpayments and Underpayments.  As a result of uncertainty in the
application of Section 280G of the Code at the time of an initial determination
by the Auditors hereunder, it is possible that Payments will have been made by
the Corporation which should not have been made (an "Overpayment") or that
additional Payments which will not have been made by the Corporation could have
been made (an "Underpayment"), consistent in each case with the calculation of
the Reduced Amount hereunder.  In the event that the Auditors, based upon the
assertion of a deficiency by the Internal Revenue Service against the
Corporation or the Participant which the Auditors believe has a high probability
of success, determine that an Overpayment has been made, such Overpayment shall
be treated for all purposes as a loan to the Participant which he or she shall
repay to the Corporation, together with interest at the applicable federal rate
provided in Section 7872(f)(2) of the Code; provided, however, that no amount
shall be payable by the Participant to the Corporation if and to the extent that
such payment would not reduce the amount which is subject to taxation under
Section 4999 of the Code.  In the event that the Auditors determine that an
Underpayment has occurred, such Underpayment shall promptly be paid or
transferred by the Corporation to or for the benefit of the Participant,
together with interest at the applicable federal rate provided in Section
7872(f)(2) of the Code.

     18.5  Related Corporations.  For purposes of this Article 18, the term
"Corporation" shall include affiliated corporations to the extent determined by
the Auditors in accordance with Section 280G(d)(5) of the Code.

                              VIGNETTE CORPORATION
                          EMPLOYEE STOCK PURCHASE PLAN


SECTION 1.  PURPOSE OF THE PLAN.

     The Plan was adopted by the Board on September __, 1998, to be effective as
of the date of the IPO.  The purpose of the Plan is to provide Eligible
Employees with an opportunity to increase their proprietary interest in the
success of the Corporation by purchasing Common Stock from the Corporation on
favorable terms and to pay for such purchases through payroll deductions.  The
Plan is intended to qualify under Section 423 of the Code.

SECTION 2.  ADMINISTRATION OF THE PLAN.

     (a) Committee Composition.  The Plan shall be administered by the
Committee.  The Committee shall consist exclusively of one or more directors of
the Corporation, who shall be appointed by the Board.

     (b) Committee Responsibilities.  The Committee shall interpret the Plan and
make all other policy decisions relating to the operation of the Plan.  The
Committee may adopt such rules, guidelines and forms as it deems appropriate to
implement the Plan.  The Committee's determinations under the Plan shall be
final and binding on all persons.

SECTION 3.  ENROLLMENT AND PARTICIPATION.

     (a) Offering Periods.  While the Plan is in effect, two overlapping
Offering Periods shall commence in each calendar year.  The Offering Periods
shall consist of the 24-month periods commencing on each May 1 and November 1,
except that the first Offering Period shall commence on the date of the IPO and
end on April 30, 2000.

     (b) Accumulation Periods.  While the Plan is in effect, two Accumulation
Periods shall commence in each calendar year.  The Accumulation Periods shall
consist of the six-month periods commencing on each May 1 and November 1, except
that the first Accumulation Period shall commence on the date of the IPO and end
on April 30, 1999.

     (c) Enrollment.  Any individual who, on the 90th day prior to the first day
of an Offering Period, qualifies as an Eligible Employee may elect to become a
Participant in the Plan for such Offering Period by executing the enrollment
form prescribed for this purpose by the Committee.  The enrollment form shall be
filed with the Corporation at the prescribed location not later than one
business day prior to the commencement of such Offering Period.
<PAGE>
 
     (d) Duration of Participation.  Once enrolled in the Plan, a Participant
shall continue to participate in the Plan until he or she ceases to be an
Eligible Employee, withdraws from the Plan under Section 5(a) or reaches the end
of the Accumulation Period in which his or her employee contributions were
discontinued under Section 4(d) or 8(b).  A Participant who discontinued
employee contributions under Section 4(d) or withdrew from the Plan under
Section 5(a) may again become a Participant, if he or she then is an Eligible
Employee, by following the procedure described in Subsection (c) above.  A
Participant whose employee contributions were discontinued automatically under
Section 8(b) shall automatically resume participation at the beginning of the
earliest Accumulation Period ending in the next calendar year, if he or she then
is an Eligible Employee.

     (e) Applicable Offering Period.  For purposes of calculating the Purchase
Price under Section 7(b), the applicable Offering Period shall be determined as
follows:

     (i)   Once a Participant is enrolled in the Plan for an Offering Period,
such Offering Period shall continue to apply to him or her until the earliest of
(A) the end of such Offering Period, (B) the end of his or her participation
under Subsection (d) above or (C) re-enrollment for a subsequent Offering Period
under Paragraph (ii) or (iii) below.

     (ii)  In the event that the Fair Market Value of the Common Stock on the
last trading day before the commencement of the Offering Period for which the
Participant is enrolled is higher than on the last trading day before the
commencement of any subsequent Offering Period, the Participant shall
automatically be re-enrolled for such subsequent Offering Period.

     (iii) Any other provision of the Plan notwithstanding, the Corporation (at
its sole discretion) may determine prior to the commencement of any new Offering
Period that all Participants shall be re-enrolled for such new Offering Period.

     (iv)  When a Participant reaches the end of an Offering Period but his or
her participation is to continue, then such Participant shall automatically be
re-enrolled for the Offering Period that commences immediately after the end of
the prior Offering Period.

SECTION 4.  EMPLOYEE CONTRIBUTIONS.

     (a) Frequency of Payroll Deductions.  A Participant may purchase shares of
Common Stock under the Plan solely by means of payroll deductions.  Payroll
deductions, as designated by the Participant pursuant to Subsection (b) below,
shall occur on each payday during participation in the Plan.

     (b) Amount of Payroll Deductions.  An Eligible Employee shall designate on
the enrollment form the portion of his or her Compensation that he or she elects
to have withheld for 

                                       2
<PAGE>
 
the purchase of Common Stock. Such portion shall be a whole percentage of the
Eligible Employee's Compensation, but not less than 1% nor more than 15% or such
lesser percentage established by the Committee from time to time.

     (c) Changing Withholding Rate.  If a Participant wishes to change the rate
of payroll withholding, he or she may do so by filing a new enrollment form with
the Corporation at the prescribed location at any time.  The new withholding
rate shall be effective as soon as reasonably practicable after such form has
been received by the Corporation.  The new withholding rate shall be a whole
percentage of the Eligible Employee's Compensation, but not less than 1% nor
more than 15%.

     (d) Discontinuing Payroll Deductions.  If a Participant wishes to
discontinue employee contributions entirely, he or she may do so by filing a new
enrollment form with the Corporation at the prescribed location at any time.
Payroll withholding shall cease as soon as reasonably practicable after such
form has been received by the Corporation.  (In addition, employee contributions
may be discontinued automatically pursuant to Section 8(b).)  A Participant who
has discontinued employee contributions may resume such contributions by filing
a new enrollment form with the Corporation at the prescribed location.  Payroll
withholding shall resume as soon as reasonably practicable after such form has
been received by the Corporation.

     (e) Limit on Number of Elections.  No Participant shall make more than one
election under Subsection (c) or (d) above during any Accumulation Period.

SECTION 5.  WITHDRAWAL FROM THE PLAN.

     (a) Withdrawal.  A Participant may elect to withdraw from the Plan by
filing the prescribed form with the Corporation at the prescribed location at
any time before the last day of an Accumulation Period.  As soon as reasonably
practicable thereafter, payroll deductions shall cease and the entire amount
credited to the Participant's Plan Account shall be refunded to him or her in
cash, without interest.  No partial withdrawals shall be permitted.

     (b) Re-Enrollment After Withdrawal.  A former Participant who has withdrawn
from the Plan shall not be a Participant until he or she re-enrolls in the Plan
under Section 3(c).  Re-enrollment may be effective only at the commencement of
an Offering Period.

SECTION 6.  CHANGE IN EMPLOYMENT STATUS.

     (a) Termination of Employment.  Termination of employment as an Eligible
Employee for any reason, including death, shall be treated as an automatic
withdrawal from the Plan under Section 5(a).  (A transfer from one Participating
Corporation to another shall not be treated as a termination of employment.)

     (b) Leave of Absence.  For purposes of the Plan, employment shall not be
deemed to terminate when the Participant goes on a military leave, a sick leave
or another bona fide leave of 

                                       3
<PAGE>
 
absence, if the leave was approved by the Corporation in writing. Employment,
however, shall be deemed to terminate 90 days after the Participant goes on a
leave, unless a contract or statute guarantees his or her right to return to
work. Employment shall be deemed to terminate in any event when the approved
leave ends, unless the Participant immediately returns to work.

     (c) Death.  In the event of the Participant's death, the amount credited to
his or her Plan Account shall be paid to a beneficiary designated by him or her
for this purpose on the prescribed form or, if none, to the Participant's
estate.  Such form shall be valid only if it was filed with the Corporation at
the prescribed location before the Participant's death.

SECTION 7.  PLAN ACCOUNTS AND PURCHASE OF SHARES.

     (a) Plan Accounts.  The Corporation shall maintain a Plan Account on its
books in the name of each Participant.  Whenever an amount is deducted from the
Participant's Compensation under the Plan, such amount shall be credited to the
Participant's Plan Account.  Amounts credited to Plan Accounts shall not be
trust funds and may be commingled with the Corporation's general assets and
applied to general corporate purposes.  No interest shall be credited to Plan
Accounts.

     (b) Purchase Price.  The Purchase Price for each share of Common Stock
purchased at the close of an Accumulation Period shall be the lower of:

         (i)  85% of the Fair Market Value of such share on the last trading day
in such Accumulation Period; or

         (ii) 85% of the Fair Market Value of such share on the last trading day
before the commencement of the applicable Offering Period (as determined under
Section 3(e)) or, in the case of the first Offering Period under the Plan, 85%
of the price at which one share of Common Stock is offered to the public in the
IPO.

     (c) Number of Shares Purchased.  As of the last day of each Accumulation
Period, each Participant shall be deemed to have elected to purchase the number
of shares of Common Stock calculated in accordance with this Subsection (c),
unless the Participant has previously elected to withdraw from the Plan in
accordance with Section 5(a).  The amount then in the Participant's Plan Account
shall be divided by the Purchase Price, and the number of shares that results
shall be purchased from the Corporation with the funds in the Participant's Plan
Account.  The foregoing notwithstanding, no Participant shall purchase more than
2,000 shares [post-split] of Common Stock with respect to any Accumulation
Period nor more than the amounts of Common Stock set forth in Sections 8(b) and
13(a).  The Committee may determine with respect to all Participants that any
fractional share, as calculated under this Subsection (c), shall be (i) rounded
down to the next lower whole share or (ii) credited as a fractional share.

     (d) Available Shares Insufficient.  In the event that the aggregate number
of shares that all Participants elect to purchase during an Accumulation Period
exceeds the maximum number of shares remaining available for issuance under
Section 13(a), then the number of shares 

                                       4
<PAGE>
 
to which each Participant is entitled shall be determined by multiplying the
number of shares available for issuance by a fraction, the numerator of which is
the number of shares that such Participant has elected to purchase and the
denominator of which is the number of shares that all Participants have elected
to purchase.

     (e) Issuance of Common Stock.  Certificates representing the shares of
Common Stock purchased by a Participant under the Plan shall be issued to him or
her as soon as reasonably practicable after the close of the applicable
Accumulation Period, except that the Committee may determine that such shares
shall be held for each Participant's benefit by a broker designated by the
Committee (unless the Participant has elected that certificates be issued to him
or her).  Shares may be registered in the name of the Participant or jointly in
the name of the Participant and his or her spouse as joint tenants with right of
survivorship or as community property.  The Committee may impose such
restrictions on the transfer or resale of issued shares as it may deem
advisable.

     (f) Unused Cash Balances.  An amount remaining in the Participant's Plan
Account that represents the Purchase Price for any fractional share shall be
carried over in the Participant's Plan Account to the next Accumulation Period.
Any amount remaining in the Participant's Plan Account that represents the
Purchase Price for whole shares that could not be purchased by reason of
Subsection (c) above, Section 8(b) or Section 13(a) shall be refunded to the
Participant in cash, without interest.

     (g) Stockholder Approval.  Any other provision of the Plan notwithstanding,
no shares of Common Stock shall be purchased under the Plan unless and until the
Corporation's stockholders have approved the adoption of the Plan.

SECTION 8.  LIMITATIONS ON STOCK OWNERSHIP.

     (a) Five Percent Limit.  Any other provision of the Plan notwithstanding,
no Participant shall be granted a right to purchase Common Stock under the Plan
if such Participant, immediately after his or her election to purchase such
Common Stock, would own stock possessing more than 5% of the total combined
voting power or value of all classes of stock of the Corporation or any parent
or Subsidiary of the Corporation.  For purposes of this Subsection (a), the
following rules shall apply:

         (i)   Ownership of stock shall be determined after applying the
attribution rules of section 424(d) of the Code;

         (ii)  Each Participant shall be deemed to own any stock that he or she
has a right or option to purchase under this or any other plan; and

         (iii) Each Participant shall be deemed to have the right to purchase
2,000 shares [post-split] of Common Stock under this Plan with respect to each
Accumulation Period.

                                       5
<PAGE>
 
     (b) Dollar Limit.  Any other provision of the Plan notwithstanding, no
Participant shall purchase Common Stock with a Fair Market Value in excess of
the following limit:

         (i)   In the case of Common Stock purchased during an Offering Period
that commenced in the current calendar year, the limit shall be equal to (A)
$25,000 minus (B) the Fair Market Value of the Common Stock that the Participant
previously purchased in the current calendar year (under this Plan and all other
employee stock purchase plans of the Corporation or any parent or Subsidiary of
the Corporation).

         (ii)  In the case of Common Stock purchased during an Offering Period
that commenced in the immediately preceding calendar year, the limit shall be
equal to (A) $50,000 minus (B) the Fair Market Value of the Common Stock that
the Participant previously purchased (under this Plan and all other employee
stock purchase plans of the Corporation or any parent or Subsidiary of the
Corporation) in the current calendar year and in the immediately preceding
calendar year.

         (iii) In the case of Common Stock purchased during an Offering Period
that commenced in the second preceding calendar year, the limit shall be equal
to (A) $75,000 minus (B) the Fair Market Value of the Common Stock that the
Participant previously purchased (under this Plan and all other employee stock
purchase plans of the Corporation or any parent or Subsidiary of the
Corporation) in the current calendar year and in the two preceding calendar
years.

For purposes of this Subsection (b), the Fair Market Value of Common Stock shall
be determined in each case as of the beginning of the Offering Period in which
such Common Stock is purchased.  Employee stock purchase plans not described in
section 423 of the Code shall be disregarded.  If a Participant is precluded by
this Subsection (b) from purchasing additional Common Stock under the Plan, then
his or her employee contributions shall automatically be discontinued and shall
resume at the beginning of the earliest Accumulation Period ending in the next
calendar year (if he or she then is an Eligible Employee).

SECTION 9.  RIGHTS NOT TRANSFERABLE.

     The rights of any Participant under the Plan, or any Participant's interest
in any Common Stock or moneys to which he or she may be entitled under the Plan,
shall not be transferable by voluntary or involuntary assignment or by operation
of law, or in any other manner other than by beneficiary designation or the laws
of descent and distribution.  If a Participant in any manner attempts to
transfer, assign or otherwise encumber his or her rights or interest under the
Plan, other than by beneficiary designation or the laws of descent and
distribution, then such act shall be treated as an election by the Participant
to withdraw from the Plan under Section 5(a).

                                       6
<PAGE>
 
SECTION 10. NO RIGHTS AS AN EMPLOYEE.

     Nothing in the Plan or in any right granted under the Plan shall confer
upon the Participant any right to continue in the employ of a Participating
Corporation for any period of specific duration or interfere with or otherwise
restrict in any way the rights of the Participating Corporations or of the
Participant, which rights are hereby expressly reserved by each, to terminate
his or her employment at any time and for any reason, with or without cause.

SECTION 11. NO RIGHTS AS A STOCKHOLDER.

     A Participant shall have no rights as a stockholder with respect to any
shares of Common Stock that he or she may have a right to purchase under the
Plan until such shares have been purchased on the last day of the applicable
Accumulation Period.

SECTION 12. SECURITIES LAW REQUIREMENTS.

     Shares of Common Stock shall not be issued under the Plan unless the
issuance and delivery of such shares comply with (or are exempt from) all
applicable requirements of law, including (without limitation) the Securities
Act of 1933, as amended, the rules and regulations promulgated thereunder, state
securities laws and regulations, and the regulations of any stock exchange or
other securities market on which the Corporation's securities may then be
traded.

SECTION 13. STOCK OFFERED UNDER THE PLAN.

     (a) Authorized Shares.  The aggregate number of shares of Common Stock
available for purchase under the Plan shall be 750,000 [post-split], subject to
adjustment pursuant to this Section 13.  In addition, the number of shares of
Common Stock available for purchase under the Plan shall automatically increase
by the lesser of (i) 2% of the total number of shares of Common Stock
outstanding or (ii) 750,000 shares [post-split] on January 1, 1999, January 1,
2000, January 1, 2001, and January 1, 2002.

     (b) Anti-Dilution Adjustments.  The aggregate number of shares of Common
Stock offered under the Plan, the number of shares by which the share reserve is
to increase each calendar year, the 2,000-share [post-split] limitation
described in Section 7(c) and the price of shares that any Participant has
elected to purchase shall be adjusted proportionately by the Committee for any
increase or decrease in the number of outstanding shares of Common Stock
resulting from a subdivision or consolidation of shares or the payment of a
stock dividend, any other increase or decrease in such shares effected without
receipt or payment of consideration by the Corporation, the distribution of the
shares of a Subsidiary to the Corporation's stockholders or a similar event.

     (c) Reorganizations.  Any other provision of the Plan notwithstanding,
immediately prior to the effective time of a Corporate Reorganization, the
Offering Period and Accumulation Period then in progress shall terminate and
shares shall be purchased pursuant to Section 7, unless the Plan is assumed by
the surviving corporation or its parent corporation pursuant to the 

                                       7
<PAGE>
 
plan of merger or consolidation. The Plan shall in no event be construed to
restrict in any way the Corporation's right to undertake a dissolution,
liquidation, merger, consolidation or other reorganization.

SECTION 14. AMENDMENT OR DISCONTINUANCE.

     The Board shall have the right to amend, suspend or terminate the Plan at
any time and without notice.  Except as provided in Section 13, any increase in
the aggregate number of shares of Common Stock to be issued under the Plan shall
be subject to approval by a vote of the stockholders of the Corporation.  In
addition, any other amendment of the Plan shall be subject to approval by a vote
of the stockholders of the Corporation to the extent required by an applicable
law or regulation.

<PAGE>
 
                              VIGNETTE CORPORATION
                    1998 NON-EMPLOYEE DIRECTORS OPTION PLAN
                                        


ARTICLE 1. PURPOSE OF THE PLAN

           The Plan is intended to promote the interests of the Corporation by
providing the non-employee members of the Board with the opportunity to acquire
a proprietary interest, or otherwise increase their proprietary interest, in the
Corporation as an incentive for them to remain in the service of the
Corporation.

ARTICLE 2. ADMINISTRATION

           The terms and conditions of each automatic option grant (including 
the timing and pricing of the option grant) shall be determined by the express
terms and conditions of the Plan, and neither the Board nor any committee of the
Board shall exercise any discretionary functions with respect to option grants
made pursuant to the Plan.

ARTICLE 3. STOCK SUBJECT TO THE PLAN

           A.  Shares of Common Stock shall be available for issuance under the
Plan and shall be drawn from either the Corporation's authorized but unissued
shares of Common Stock or from reacquired shares of Common Stock, including
shares repurchased by the Corporation on the open market. The number of shares
of Common Stock reserved for issuance over the term of the Plan shall be fixed
at 250,000 shares [post-split].

           B.  Should one or more outstanding options under this Plan expire or 
terminate for any reason prior to exercise in full, then the shares subject to
the portion of each option not so exercised shall be available for subsequent
option grant under the Plan. In addition, should the exercise price of an
outstanding option under the Plan be paid with shares of Common Stock, then the
number of shares of Common Stock available for issuance under the Plan shall be
reduced by the net number of shares of Common Stock actually issued to the
holder of such option.

           C.  Should any change be made to the Common Stock issuable under the 
Plan by reason of any stock split, stock dividend, recapitalization, combination
of shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without the Corporation's receipt of consideration, then
appropriate adjustments shall be made to (i) the maximum number and/or class of
securities issuable under the Plan, (ii) the number and/or class of securities
for which automatic option grants are to be subsequently made to each newly-
elected or continuing non-employee Board member under the Plan, and (iii) the
number and/or class of securities and price per share in effect under each
option outstanding under the Plan. The adjustments to the outstanding options
shall be made by the Board in a manner which shall preclude the enlargement or
dilution of rights and benefits under such options and shall be final, binding
and conclusive.
<PAGE>
 
ARTICLE 4. ELIGIBILITY

          The individuals eligible to receive automatic option grants pursuant
to the provisions of this Plan shall be limited to (i) those individuals serving
as non-employee Board members on the Effective Date and (ii) those individuals
who are first elected or appointed as non-employee Board members after the
Effective Date, whether through appointment by the Board or election by the
Corporation's stockholders. A non-employee Board member shall not be eligible to
receive the initial automatic option grant if such individual has previously
been in the employ of the Corporation (or any parent or subsidiary). However, a
non-employee Board member shall be eligible to receive one or more annual option
grants, whether or not he or she has previously been in the employ of the
Corporation (or any parent or subsidiary). Each non-employee Board member
eligible to participate in the Plan pursuant to the foregoing criteria is hereby
designated an Eligible Director.

ARTICLE 5. TERMS AND CONDITIONS OF AUTOMATIC OPTION GRANTS

          A.   Grant Date.  Option grants shall be made on the dates specified
               ----------                                                   
below:

          -    Each individual who first becomes an Eligible Director on or
     after the Effective Date, whether through election by the Corporation's
     stockholders or appointment by the Board, shall automatically be granted,
     at the time of such initial election or appointment, a non-statutory option
     to purchase 25,000 shares [post-split] of Common Stock.

          -    On the date of each Annual Meeting, beginning with the 1999
     Annual Meeting, each Eligible Director who serves on the Board at the time
     of that Annual Meeting, whether or not standing for re-election, shall
     automatically be granted a non-statutory option to purchase 2,500 shares
     [post-split] of Common Stock. An Eligible Director who resigns effective at
     an Annual Meeting shall not be eligible to be granted a non-statutory
     option at that time.

          There shall be no limit on the number of such annual 2,500-share
[post-split] option grants any one Eligible Director may receive over his or her
period of continued Board service.

          B.   Exercise Price.  The exercise price per share of Common Stock 
               -------------- 
subject to each automatic option grant shall be equal to one hundred percent
(100%) of the Fair Market Value per share of Common Stock on the automatic grant
date.

          C.   Payment.
               ------- 

          The exercise price shall become immediately due upon exercise of the
option and shall be payable in one of the alternative forms specified below:

                    (i)  full payment in cash or check made payable to the
Corporation's order; or
                                       
                                       2
<PAGE>
 
                    (ii)  full payment in shares of Common Stock held for the 
requisite period necessary to avoid a charge to the Corporation's earnings for
financial-reporting purposes and valued at Fair Market Value on the Exercise
Date (as such term is defined below); or

                    (iii) full payment in a combination of shares of Common 
Stock held for the requisite period necessary to avoid a charge to the
Corporation's earnings for financial-reporting purposes and valued at Fair
Market Value on the Exercise Date and cash or check payable to the Corporation's
order; or

                    (iv)  full payment through a broker-dealer sale and 
remittance procedure pursuant to which the non-employee Board member (i) shall
provide irrevocable written instructions to a Corporation-designated brokerage
firm to effect the immediate sale of the purchased shares and remit to the
Corporation, out of the sale proceeds available on the settlement date,
sufficient funds to cover the aggregate exercise price payable for the purchased
shares and (ii) shall concurrently provide written directives to the Corporation
to deliver the certificates for the purchased shares directly to such brokerage
firm in order to complete the sale transaction.

          For purposes of this Section 5.C, the Exercise Date shall be the date
on which written notice of the option exercise is delivered to the Corporation.
Except to the extent the sale and remittance procedure specified above is used,
payment of the exercise price for the purchased shares must accompany the
exercise notice.

          D.  Exercisability/Vesting.  Each automatic grant shall become 
              ---------------------- 
exercisable for 25% of the option shares upon the optionee's completion of one
year of Board service and for the balance of the option shares in a series of
equal quarterly installments over the next three years upon the optionee's
completion of each six-month period of Board service thereafter.

          Exercisability of the option shall be subject to acceleration as
provided in Section 5.G and Article 6. In no event, however, shall the option
become exercisable for any additional option shares after the Optionee's
cessation of Board service.

          E.  Option Term.  Each automatic grant under the Plan shall have a 
              ----------- 
maximum term of ten (10) years measured from the automatic grant date.

          F.  Non-Transferability.  During the lifetime of the Optionee, each 
              ------------------- 
automatic option grant shall be exercisable only by the Optionee and shall not
be assignable or transferable by the Optionee other than a transfer of the
option effected by will or by the laws of descent and distribution following
Optionee's death.

          G.  Effect of Termination of Board Service.
              -------------------------------------- 

               1.  Should the Optionee cease to serve as a Board member for 
any reason (other than death) while holding one or more automatic option grants
under the Plan, then such individual shall have a twelve (12)-month period
following the date of such cessation of Board service in which to exercise each
such option for any or all of the option shares for which

                                       3
<PAGE>
 
the option is exercisable at the time of his or her cessation of Board service.
Each such option shall immediately terminate and cease to be outstanding, at the
time of such cessation of Board service, with respect to any option shares for
which the option is not otherwise at that time exercisable.

               2.  Should the Optionee die while serving as a Board member or 
within twelve (12) months after cessation of Board service, then any automatic
option grant held by the Optionee at the time of death may subsequently be
exercised, for the option shares for which the option is exercisable at the time
of his or her cessation of Board service (less any option shares purchased by
the Optionee prior to death), by the personal representative of the Optionee's
estate or by the person or persons to whom the option is transferred pursuant to
the Optionee's will or in accordance with the laws of descent and distribution.
The right to exercise each such option shall lapse upon the expiration of the
twelve (12)-month period measured from the date of the Optionee's cessation of
service.

               3.  In no event shall any automatic grant under this Plan remain 
exercisable after the expiration date of the maximum ten (10)-year option term.
Upon the expiration of the applicable post-service exercise period under
subparagraphs 1 through 3 above or (if earlier) upon the expiration of the
maximum ten (10)-year option term, the automatic grant shall terminate and cease
to be outstanding for any option shares for which the option was not exercisable
at the time of the Optionee's cessation of Board service.

          H.   Stockholder Rights.  The holder of an automatic option grant    
               ------------------  
shall have none of the rights of a stockholder with respect to any shares
subject to such option until such individual shall have exercised the option and
paid the exercise price for the purchased shares.

          I.   Remaining Terms.  The remaining terms and conditions of each 
               --------------- 
automatic option grant shall be as set forth in the form Stock Option Agreement
approved for use under the Plan.

ARTICLE 6.  SPECIAL ACCELERATION EVENTS

          A.   In the event of any Change in Control, the shares of Common Stock
at the time subject to each outstanding option but not otherwise fully
exercisable shall automatically accelerate in full so that each such option
shall, immediately prior to the specified effective date for the Change in
Control, become fully exercisable for all of the shares of Common Stock at the
time subject to that option. Immediately following the consummation of the
Change in Control, each automatic option grant under the Plan shall terminate
and cease to be outstanding, except to the extent assumed by the successor
corporation or its parent company.

          B.   The automatic option grants outstanding under the Plan shall in 
no way affect the right of the Corporation to adjust, reclassify, reorganize or
otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

option grants.

over the Plan, the options granted under it, and the Common Stock issued

                                 IMPERIAL BANK
                                  Member FDIC

                          SECURITY AND LOAN AGREEMENT
                             (ACCOUNTS RECEIVABLE)

This Agreement is entered into between VIGNETTE CORPORATION, a DELAWARE
CORPORATION (herein called "Borrower") and IMPERIAL BANK (herein called "Bank").

1.   Bank hereby commits, subject to all the terms and conditions of this
     Agreement and prior to the termination of its commitment as hereinafter
     provided, to make loans to Borrower from time to time in such amounts as
     may be determined by Bank up to, but not exceeding in the aggregate unpaid
     principal balance, the following Borrowing Base:

                           80 % of Eligible Accounts

     and in no event more than $ 3,000,000.00 provided herein that only
     outstandings over $1,500,000.00 shall be subject to the Borrowing Base
     Line.

2.   The amount of each loan made by Bank to Borrower hereunder shall be debited
     to the loan ledger account of Borrower maintained by Bank (herein called
     "Loan Account") and Bank shall credit the Loan Account with all loan
     repayments made by Borrower. Borrower promises to pay Bank (a) the unpaid
     balance of Borrower's Loan Account on demand and (b) on or before the
     tenth day of each month, interest on the average daily unpaid balance of
     the Loan Account during the immediately preceding month at the rate of
     three quarters of one percent (0.750%) per annum in excess of the rate of
     interest which Bank has announced as its prime lending rate ("Prime Rate")
     which shall vary concurrently with any change in such Prime Rate. Interest
     shall be computed at the above rate on the basis of the actual number of
     days during which the principal balance of the loan account is outstanding
     divided by 360, which shall for interest computation purposes be considered
     one year. Bank at its option may demand payment of any or all of the amount
     due under the Loan Account including accrued but unpaid interest at any
     time. Such notice may be given verbally or in writing and should be
     effective upon receipt by Borrower. The amount of interest payable each
     month by Borrower shall not be less than a minimum monthly charge of 
     $250.00. Bank is hereby authorized to charge Borrower's deposit account(s)
     with Bank for all sums due Bank under this Agreement.

3.   Requests for loans hereunder shall be in writing duly executed by Borrower
     in a form satisfactory to Bank and shall contain a certification setting
     forth the matters referred to in Section 1, which shall disclose that
     Borrower is entitled to the amount of loan being requested.

4.   As used in this Agreement, the following terms shall have the following
     meanings:

          A.  "Accounts" means any right to payment for goods sold or leased, or
              to be sold or to be leased, or for services rendered or to be
              rendered no matter how evidenced, including accounts receivable,
              contract rights, chattel paper, instruments, purchase orders,
              notes, drafts, acceptances, general intangibles and other forms of
              obligations and receivables.

          B.  "Collateral" means any and all personal property of Borrower which
              is assigned or hereafter is assigned to Bank as security or in
              which Bank now has or hereafter acquires a security interest.

          C.  "Eligible Accounts" means all of Borrower's Accounts excluding,
              however, (1) all Accounts under which payment is not received
              within 90 days from any invoice date, (2) all Accounts against
              which the account debtor or any other person obligated to make
              payment thereon asserts any defense, offset, counterclaim or other
              right to avoid or reduce the liability represented by the Account
              and (3) any Accounts if the account debtor or any other person
              liable in connection herewith is insolvent, subject to bankruptcy
              or receivership proceedings or has made an assignment for the
              benefit of creditors or whose credit standing is unacceptable to
              Bank and Bank has so notified Borrower. Eligible Accounts shall
              only include such accounts as Bank in its sole discretion shall
              determine are eligible from time to time.

5.   Borrower hereby assigns to Bank all Borrower's present and future Accounts,
     including all proceeds due thereunder, all guaranties and security
     therefor, and hereby grants to Bank a continuing security interest in all
     moneys in the Collateral Account referred to in Section 6 hereof, as
     security for any and all obligations of Borrower to Bank, whether now owing
     or hereafter incurred and whether direct, indirect, absolute or contingent.
     So long as Borrower is indebted to Bank or Bank is committed to extend
     credit to Borrower, Borrower will execute and deliver to Bank such
     assignments, including Bank's standard forms of Specific or General
     Assignment covering individual Accounts, notices, financing statements, and
     other documents and papers as Bank may require in order to affirm,
     effectuate or further assure the assignment to Bank of the Collateral or to
     give any third party, including the account debtors obligated on the
     Accounts, notice of Bank's interest in the Collateral.

6.   Until Bank exercises its rights to collect the Accounts pursuant to
     paragraph 10, Borrower will collect with diligence all Borrower's Accounts,
     provided that no legal action shall be maintained thereon or in connection
     therewith without Bank's prior written consent. Any collection of Accounts
     by Borrower, whether in the form of cash, checks, notes, or other
     instruments for the payment of money (properly endorsed or assigned where
     required to enable Bank to collect same), shall be in trust for Bank, and
     Borrower shall keep all such collections separate and apart from all other
     funds and property so as to be capable of identification as the property of
     Bank and deliver said collections daily to Bank in the identical form
     received. The proceeds of such collections when received by Bank may be
     applied by Bank directly to the payment of Borrower's Loan Account or any
     other obligation secured hereby. Any credit given by Bank upon receipt of
     said proceeds shall be conditional credit subject to collection. Returned
     items at Bank's option may be charged to Borrower's general account. All
     collections of the Accounts shall be set forth on an itemized schedule,
     showing the name of the account debtor, the amount of each payment and such
     other information as Bank may request.

7.   Until Bank exercises its rights to collect the Accounts pursuant to
     paragraph 10, Borrower may continue its present policies with respect to
     returned merchandise and adjustments. However, Borrower shall immediately
     notify Bank of all cases involving returns, repossessions, and loss or
     damage of or to merchandise represented by the Accounts and of any credits,
     adjustments or disputes arising in connection with the goods or services
     represented by the Accounts and, in any of such events, Borrower will
     immediately pay to Bank from its own funds (and not from the proceeds of
     Accounts or inventory) for application to Borrower's Loan Account or any
     other obligation secured hereby the amount of any credit for such returned
     or repossessed merchandise and adjustments made to any of the Accounts.

8.   Borrower represents and warrants to Bank: (i) if Borrower is a corporation,
     that Borrower is duly organized and existing in the State of its
     incorporation and the execution, delivery and performance hereof are within
     Borrower's corporate powers, have been duly authorized and are not in
     conflict with law or the terms of any charter, by-law or other
     incorporation papers, or of any indenture, agreement or undertaking to
     which Borrower is a party or by which Borrower is found or affected; (ii)
     Borrower is, or at the time the collateral becomes subject to Bank's
     security interest will be, the true and lawful owner of and has, or at the
     time the Collateral becomes subject to Bank's security interest will have,
     good and clear title to the Collateral, subject only to Bank's rights
     therein; (iii) Each Account is, or at the time the Account comes into
     existence will be, a true and correct statement of a bona fide indebtedness
     incurred by the debtor named therein in the amount of the Account for
     either merchandise sold or delivered (or being held subject to Borrower's
     delivery instructions) to, or services rendered, performed and accepted by,
     the account debtor; (iv) That there are or will be no defenses,
     counterclaims, or setoffs which may be asserted against the Accounts; and
     (v) any and all financial information, including information relating to
     the Collateral submitted by Borrower to Bank, whether previously or in the
     future, is or will be true and correct.

  9. Borrower will: (i) Furnish Bank from time to time such financial statements
     and information as Bank may reasonably request and inform Bank immediately
     upon the occurrence of a material adverse change therein; (ii) Furnish
     Bank periodically, in such form and detail and at such times as Bank may
     require, statements showing aging and reconciliation of the Accounts and
     collections thereon; (iii) Permit representatives of Bank to inspect the
     Borrower's books and records relating to the Collateral and make extracts
     therefrom at any reasonable time and to arrange for verification of the
     Accounts, under reasonable procedures, acceptable to Bank, directly with
     the account debtors or otherwise at Borrower's expense; (iv) Promptly
     notify Bank of any attachment or other legal process levied against any of
     the Collateral and any information received by Borrower relative to the
     Collateral, including the Accounts, the account debtors or other persons
     obligated in connection therewith, which may in any way affect the value of
     the Collateral or the rights and remedies of Bank in respect thereto; (v)
     Reimburse Bank upon demand for any and all legal costs, including
     reasonable attorneys' fees, and other expense incurred in collecting any
     sums payable by Borrower under Borrower's Loan Account or any other
     obligation secured hereby, enforcing any term or provision of this Security
     Agreement or otherwise or in the checking, handling and collection of the
     Collateral and the preparation and enforcement of any agreement relating
     thereto; (vi) Notify Bank of each location and of each office of Borrower
     at which records of Borrower relating to the Accounts are kept; (vii)
     Provide, maintain and deliver to Bank policies insuring the Collateral
     against loss or damage by such risks and in such amounts, forms and
     companies as Bank may require and with loss payable solely to Bank, and, in
     the event Bank takes possession of the Collateral, the insurance policy or
     policies and any unearned or returned premium thereon shall at the option
     of Bank become the sole property of Bank, such policies and the proceeds of
     any other insurance covering or in any way relating to the Collateral,
     whether now in existence or hereafter obtained, being hereby assigned to
     Bank; (viii) in the event the unpaid balance of Borrower's Loan Account
     shall exceed the maximum amount of outstanding loans to which Borrower is
     entitled under Section 1 hereof, Borrower shall immediately pay to Bank,
     from its own funds and not from the proceeds of Collateral, for credit to
     Borrower's Loan Account the amount of such excess.
    
 10. Bank may at any time, without prior notice to Borrower, collect the
     Accounts and may give notice of assignment to any and all account debtors,
     and Borrower does hereby make, constitute and appoint Bank its irrevocable,
     true and lawful attorney with power to receive, open and dispose of all
     mail addressed to Borrower, to endorse the name of Borrower upon any checks
     or other evidences of payment that may come into the possession of Bank
     upon the Accounts to endorse the name of the undersigned upon any document
     or instrument relating to the Collateral; in its name or otherwise, to
     demand, sue for, collect and give acquittances for any and all moneys due
     or to become due upon the Accounts; to compromise, prosecute or defend any
     action, claim or proceeding with respect thereto; and to do any and all
     things necessary and proper to carry out the purpose herein contemplated.
    
 11. Until Borrower's Loan Account and all other obligations secured hereby
     shall have been repaid in full, Borrower shall not sell, dispose of or
     grant a security interest in any of the Collateral other than to Bank, or
     execute any financing statements covering the Collateral in favor of any
     secured party or person other than Bank.
    
 12. Should: (i) Default be made in the payment of any obligation, or breach be
     made in any warranty, statement, promise, term or condition, contained
     herein or hereby secured; (ii) Any statement or representation made for the
     purpose of obtaining credit hereunder prove false; (iii) Bank deem the
     Collateral inadequate or unsafe or in danger of misuse; (iv) Borrower
     become insolvent or make an assignment for the benefit of creditors; or (v)
     Any proceeding be commenced by or against Borrower under any bankruptcy,
     reorganization, arrangement, readjustment of debt or moratorium law or
     statute; then in any such event, Bank may, at its option and without demand
     first made and without notice to Borrower, do any one or more of the
     following: (a) Terminate its obligation to make loans to Borrower as
     provided in Section 1 hereof; (b) Declare all sums secured hereby
     immediately due and payable; (c) Immediately take possession of the
     Collateral wherever it may be found, using all necessary force so to do, or
     require Borrower to assemble the Collateral and make it available to Bank
     at a place designated by Bank which is reasonably convenient to Borrower
     and Bank, and Borrower waives all claims for damages due to or arising from
     or connected with any such taking; (d) Proceed in the foreclosure of Bank's
     security interest and sale of the Collateral in any manner permitted by
     law, or provided for herein; (e) Sell, lease or otherwise dispose of the
     Collateral at public or private sale, with or without having the Collateral
     at the place of sale, and upon terms and in such manner as Bank may
     determine, and Bank may purchase same at any such sale; (f) Retain the
     Collateral in full satisfaction of the obligations secured thereby; (g)
     Exercise any remedies of a secured party under the Uniform Commercial Code.
     Prior to any such disposition, Bank may, at as option, cause any of the
     Collateral to be repaired or reconditioned in such manner and to such
     extent as Bank may deem advisable, and any sums expended therefor by Bank
     shall be repaid by Borrower and secured hereby. Bank shall have the right
     to enforce one or more remedies hereunder successively or concurrently, and
     any such action shall not estop or prevent Bank from pursuing any further
     remedy which it may have hereunder or by law. If a sufficient sum is not
     realized from any such disposition of Collateral to pay all obligations
     secured by this Security Agreement, Borrower hereby promises and agrees to
     pay Bank any deficiency.
    
 13. If any writ of attachment, garnishment, execution or other legal process be
     issued against any property of Borrower, or if any assessment for taxes
     against Borrower, other than real property, is made by the Federal or State
     government or any department thereof, the obligation of Bank to make loans
     to Borrower as provided in Section 1 hereof shall immediately terminate and
     the unpaid balance of the Loan Account, all other obligations secured
     hereby and all other sums due hereunder shall immediately become due and
     payable without demand, presentment or notice.
    
 14. Borrower authorizes Bank to destroy all invoices, delivery receipts,
     reports and other types of documents and records submitted to Bank in
     connection with the transactions contemplated herein at any time subsequent
     to four months from the time such items are delivered to Bank.
    
 15. Nothing herein shall in any way limit the effect of the conditions set
     forth in any other security or other agreement executed by Borrower, but
     each and every condition hereof shall be in addition thereto.

*16. Additional Provisions: This Security and Loan Agreement is subject to the
     terms and conditions of the Credit Terms & Conditions dated Nov. 3, 1997 as

Subject:  Credit Terms and Conditions ("Agreements")   

Borrower:  Vignette Corporation

Gentlemen:

To induce you to make loans to the undersigned (herein called "Borrower"), and
in consideration of any loan or loans you, in your sole discretion, may make to
Borrower, Borrower warrants and agrees as follows:
 
A.  Borrower represents and warrants that:
    1.  EXISTENCE AND RIGHTS.
          Borrower is a Delaware corporation.
                                                     
Borrower is duly organized and existing and in good standing under the laws of
the State of Delaware and is authorized and in good standing to do business in
the State of Texas. Borrower has powers and adequate authority, rights and
franchises to own its property and to carry on its business as now conducted,
and is duly qualified and in good standing in each State in which the character
of the properties owned by it therein or the conduct of its business makes such
qualification necessary, and Borrower has the power and adequate authority to
make and carry out this Agreement. Borrower has no investment in any other
business entity.

    2.  AGREEMENT AUTHORIZED. The execution, delivery and performance of this
Agreement are duly authorized and do not require the consent or approval of any
governmental body or other regulatory authority; are not in contravention of or
in conflict with any law or regulation or any term or provision of Borrower's
articles of incorporation, by-laws, or Articles of Association, as the case may
be, and this Agreement is the valid, binding and legally enforceable obligation
of Borrower in accordance with its terms.

    3.  NO CONFLICT. The execution, delivery and performance of this Agreement
are not in contravention of or in conflict with any agreement, indenture or
undertaking to which Borrower is a party or by which it or any of its property
may be bound or affected, and do not cause any lien, charge or other encumbrance
to be created or imposed upon any such property by reason thereof.

    4.  LITIGATION. There is no litigation or other proceeding pending or
threatened against or affecting Borrower, and Burrower is not in default with
respect to any order, writ, injunction, decree or demand of any court or other
governmental or regulatory authority.

    5.  FINANCIAL CONDITION. The balance sheet of Borrower as of July 97, and
the related profit and loss statement for the 7 months ended on that date, a
copy of which has heretofore been delivered to you by Borrower, and all other
statements and data submitted in writing by Borrower to you in connection with
this request for credit are true and correct, and said balance sheet and profit
and loss statement truly present the financial condition of Borrower as of the
date thereof and the results of the operations of Borrower for the period
covered thereby, and have been prepared in accordance with generally accepted
accounting principles on a basis consistently maintained. Since such date there
have been no materially adverse changes in the financial condition or business
of Borrower. Borrower has no knowledge of any liabilities, contingent or
otherwise, at such date not reflected in said balance sheet, and Borrower has
not entered into any special commitments or substantial contracts which are not
reflected in said balance sheet, other than in the ordinary and normal course of
its business, which may have a materially adverse effect upon its financial
condition, operations or business as now conducted.

    6.  TITLE TO ASSETS. Borrower has good title to its assets, and the same are
not subject to any liens or encumbrances other than those permitted by Section
C.3 hereof.

    7.  TAX STATUS. Borrower has no liability for any delinquent state, local or
federal taxes, and if Borrower has contracted with any government agency,
Borrower has no liability for renegotiation of profits.

    8.  TRADEMARKS, PATENTS. Borrower, as of the date hereof, possesses all
necessary trademarks, trade names, copyrights, patents, patent rights, and
licenses to conduct its business as now operated, without any known conflict 
with the valid trademarks, trade names, copyrights, patents and license rights
of others.

    9.  REGULATION U. The proceeds of this loan shall not be used to purchase or
carry margin stock (as defined with Regulation U of the Board of Governors of
the Federal Reserve system).

upon the giving of notice and the lapse of time specified herein, or, if any
such event has occurred or any such condition exists, specifying the nature
thereof;

(d)  Promptly after the receipt thereof by Borrower, copies of any detailed

and (2) comprehensive general liability insurance. The amounts shall be as
required by Lessor's mortgagee or as Lessor may deem reasonably appropriate,
whichever is greater. Lessor shall have no responsibility to maintain fire and
extended coverage insurance on Lessee's contents. The portion of Lessor's
insurance premiums reasonably due to Lessee's acts or omissions or Lessee's

additional insureds.

       12.2 WAIVER OF SUBROGATION. (a) If waiver of subrogation is not contained

licenses, or invitees. Lessor shall indemnify Lessee for and shall hold Lessee
harmless from all fines, claims, liabilities, and suits (including costs and
expenses of defending against same) resulting from any breach or nonperformance

improvements, doorlock changes, or other modifications of any kind to the leased
premises without Lessor's written consent, which shall not be unreasonably
withheld. Consent for governmentally required changes may not be unreasonably
withheld. "Alterations" include but are not limited to improvements permanently
attached to the building, structural changes, roof and wall penetrations, and
all plumbing, electrical, and HVAC changes. Requests for Lessor's approval shall
be in writing and shall be detailed to Lessor's reasonable satisfaction. The
foregoing shall be done only by approval by Lessor in writing, which shall not
be unreasonably withheld. Lessee shall pay in advance for any requested
alterations, improvements, lock changes, or other modifications which are
approved and performed by Lessor. If same are performed by Lessee with Lessor's
permission, Lessee shall not allow any liens to be placed against the buildings

indemnify Lessee for any liability Lessee shall incur as a result of Lessor's
failure to comply with the provisions of this paragraph. Lessee agrees to
cooperate fully with Lessor to enable Lessor to timely comply with the
provisions of this paragraph and to immediately forward to Lessor any notice
Lessee receives regarding complaints, injuries, or claims by anyone claiming

the provisions of the Americans with Disabilities Act. Lessee shall be
responsible for any requirements under such architectural barrier laws as they
relate to Lessee's use of Lessee's office space, including, but not limited to,

failure to comply with the provisions of this paragraph.

14.1     REMOVAL OF PROPERTY BY LESSEE. Lessee may remove its trade fixtures,
furniture, and equipment only if (1) such removal is made prior to the end of
the lease term, (2) Lessee is not in default under this lease at time of

property remaining on the leased premises after moveout. Lessee may not remove
any alterations as defined in paragraph 13.1 or improvements such as wall-to-
wall carpeting, book shelves, window coverings, drapes, cabinets, paneling,
counters, kitchen or breakdown built-ins, shelving, wall covering, and anything
else attached to the floor, walls, or ceilings. If Lessor requests in writing,

mortgage this lease and may not grant licenses, commissions, or other rights of
occupancy to all or any part of the leased premises without Lessor's prior

financial strength, reputation, personnel, and length of sublease or assignment
shall be important factors in Lessor's approval. Sale, transfer, or merger of
the majority of the voting shares or voting partnership interests in Lessee (if
a corporation or partnership) shall be considered an assignment; likewise for
issuance of treasury stock or admission of a new general partner. Lessee shall
have the right with prior written notice to Lessor to sublease or assign any
portion or all of their premises to subsidiary or affiliated company or to any
corporate successor (upon merger or consolidation) without the consent of
Lessor, however, Lessee shall not be released from liability. Lessor shall be
entitled to (1) 50% of any excess between Lessee's rental per square foot under
the lease and the rental per square foot under the sublease or assignment, and
(2) 50% of any other consideration flowing directly or indirectly from the
sublessee or assignee to Lessee or Lessee's agents. The forgoing is in
consideration of additional management performed or to be performed by Lessor
under such sublease or assignment. Violation of this lease by sublessees or
assignees shall be deemed a violation by Lessee. Approval by Lessor of any
sublease or assignment shall not release Lessee from any obligation under this
lease for all of Lessee's obligations under this lease unless otherwise
specified in writing. Upon default by Lessee, any Sublessee shall pay all
sublease rentals and other sums due Lessor, direct to Lessor, to be credited
against sums owed to Lessor by Lessee under this lease. Unless otherwise agreed
in writing, no sublease or assignment shall be valid unless (1) a copy of this
lease is attached thereto, (2) the sublessee or assignee agrees in writing to be
liable for all of Lessee's obligations under this lease, and (3) Lessor's
written approval is attached to the sublease or assignment.

16.1     DESTRUCTION BY FIRE OR OTHER CASUALTY. (a) Total destruction, rent
abatement, and restoration. If Lessee's office space is totally damaged by fire
or other casualty so that it cannot reasonably be used by Lessee and if this

operating expenses until Lessee's office space is restored by lessor and Lessee.

                       (b) Partial destruction, rent abatement, and restoration.

hazard so that it can be only partially used by Lessee for the purposes allowed
in this lease and if this lease is not terminated as provided in subparagraph
(d) below, there shall be a partial abatement of Lessee's rent and Lessee's
obligation to pay office building operating expenses which fairly and reasonably
corresponds to the time and extent to which Lessee's office space cannot
reasonably be used by Lessee.

                       (c) Restoration. Lessor' s obligations to restore shall
be limited to the condition of the leased premises existing prior to the
casualty. Lessor shall proceed with diligence to restore. During restoration,
Lessee shall continue business to the extent practical in Lessee's reasonable
judgment.

                       (d) Lease termination. If Lessee's office space or the
office center is so badly damaged that restoration and repairs cannot be
completed within three (3) months after the fire or casualty, then this lease
may be terminated as of the date of the destruction by either Lessor or Lessee
by serving written notice upon the other. Termination notice must be delivered
within 30 days after the casualty.

17.1     CONDEMNATION. If the leased premises or any material portion thereof,

condemning authority pursuant to such taking or acquisition; and Lessor and
Lessee shall be relieved of all further obligations under this lease. Lessor
shall be entitled to recover from the condemning authority the full amount of
Lessor's interest in this lease and in the property which is taken in
condemnation; provided, however, if Lessee is not in default hereunder on the
day of taking or acquisition by the condemning authority, Lessee shall be
allowed to recover from the condemning authority, at Lessee's own expense, the
value of Lessee's remaining leasehold interest and Lessee's trade fixtures, if
any, which are taken in condemnation; but not otherwise. Lessee shall be
responsible for Lessee's own attorney's fees and for proving its own damages.

18.1     DEFAULT BY LESSOR. Lessee shall be entitled to recover actual damages
and terminate this lease if (1) Lessor fails to pay any sum due and owing to
Lessee within 7 days after written demand from Lessee, or (2) Lessor remains in
default on any other obligation for 7 days after Lessee's written demand for
performance. However, Lessor shall not be in default if Lessor promptly
commences to cure such noncompliance and diligently proceeds in good faith to
cure same after receiving written notice of such default. If taxes and utilities
are not timely paid, Lessee may pay same to the extent that it is necessary to
avert foreclosure or cutoff. If Lessor fails to perform any covenant, term or
condition of this lease that Lessor is obligate to perform and, as a consequence
of such nonperformance, Lessee shall recover a money judgment against Lessor,
such judgment shall be satisfied only out of Lessor's equity in the property.
Lessor shall have no liability whatsoever for any deficiency, and no other
property or assets of Lessor shall be subject to levy, execution or other
enforcement procedures as a result of such judgment.

19.1     DEFAULT BY LESSEE. If Lessee defaults, Lessor shall have any or all
remedies set forth below.

                       (a) Definition of default. the occurrence of any of the
following shall constitute a default by Lessee: (1) failure to pay rent or any
other sum due by Lessee under this lease within 7 days after written demand
therefor by Lessor; (2) failure to vacate on or before the last day of the lease
term, renewal term, or extension period; (3) failure to pay rent in advance on a
daily basis in the event of unlawful holdover by Lessee; (4) acquisition of
Lessee's interest in the lease by a third party by judicial or non-judicial
process; or (5) failure to comply with any other provision of the lease
(including rules) if such failure to comply is not cured within 30 days after
receiving notice or, if compliance is not possible within 30 days, as soon as
possible after delivery of written notice by Lessor to Lessee. However, Lessee
shall not be in default under subclause (5) above if Lessee promptly commences
to cure such noncompliance and diligently proceeds in good faith to cure same
after receiving written notice of such default.

                       (b) Utilities and services. If Lessee is in default for
nonpayment of rent or other sums due and if Lessee fails to pay same in full
within five (5) business days after Lessor hand delivers to Lessee or to
Lessee's representative written notice of Lessor's intent to terminate utilities
or services which are furnished by Lessor, then Lessor may terminate such
utilities or services after such five (5) business day notice period, without
further notice. Lessor's right to terminate such utilities or services shall
occur automatically and without notice if Lessee's rent is accelerated under
subparagraph (d) below, relating to unlawful early move-out.

                       (c) Acceleration after notice of rental delinquency. If
Lessee is in default for nonpayment of rent or other sums due and if Lessee
fails to pay same in full within five (5) business days after Lessor delivers to
Lessee or to Lessee's office space a written notice of Lessor's intent to
accelerate, then all rent for the remainder of the lease term shall be
accelerated, due, and delinquent at the end of five (5) business day notice
period without further demand or notice. Such acceleration rights are in
consideration of the rentals for the entire term being payable in monthly
installments rather than in one lump sum at the beginning of the lease term. If
Lessee has already vacated the leased premises, notice of acceleration may be
delivered to Lessee pursuant to paragraph 29.1. Liability for additional rents
accruing in the future (over and above any base rents) shall not be waived by
such acceleration.

                       (d) Termination of possession. If Lessee is in default as
defined in subparagraph (a) above and if Lessee remains in default for 3 days
after Lessor gives notice of such default to Lessee, or if Lessee abandons the
leased premises, Lessor may (with or without demand for performance) terminate
Lessee's right of possession by giving five (5) business day's written notice to
vacate; and Lessor shall be entitled to immediate possession without termination
of Lessee's obligations under the lease. Lessor's repossession shall not be
considered an election to terminate this lease unless written notice of such
intention to terminate is given to Lessee

by Lessor. Repossession may be voluntary agreement or by eviction lawsuit.
Commencement of an eviction lawsuit shall not preclude other Lessor remedies
under this lease or other laws.

                       (e) Reletting costs. If Lessee is in default under this
lease and if Lessor terminates Lessee's rights of possession without terminating
this lease and Lessee's space is released, Lessee shall pay upon Lessor's demand
the following: (1) all costs of reletting including, leasing commissions,
utilities during the vacancy, advertising costs, administrative overhead, and
all costs of repair, remodeling, or redecorating for replacement tenants in
Lessee's office space, (2) all rent and other indebtedness due from Lessee to
Lessor through the date of termination of Lessee's right of possession, and (3)
all rent and other sums required to be paid by Lessee during the remainder of
the entire lease term, subject to the acceleration paragraphs above.

                       (f) Mitigation by Lessor. Upon eviction or voluntary
vacation of the leased premises by Lessee without the lease being terminated by
Lessor, Lessor shall make reasonable efforts to relet the leased premises. After
deduction of reasonable expenses incurred by Lessor, Lessee shall receive credit
for any rentals received by Lessor through reletting the leased premises during
the remainder of the lease term or renewal or extension period. Such deductible
expenses may include real estate commissions, attorney's fees, and all other
expenses in connection with reletting. Lawsuit to collect amounts due by Lessee
under this lease may be brought from time to time on one or more occasions
without the necessity of Lessor's waiting until the expiration of the lease
term. If judgment for accelerated rents is recovered, Lessor shall give credit
against such judgment for subsequent payments made by Lessee and subsequent
rentals receive by Lessor from other tenants of Lessee's office space, less
lawful deductions and expenses of reletting.

                       (g) Termination of lease. Lessor may terminate this lease
(as contrasted to termination of possession rights only) upon default by Lessee
or at any time after Lessor's lawful re-entry or repossession following default
by Lessee. Lessor's agents have authority to terminate the lease only by written
notice given pursuant to paragraph 29.1.

                       (h) Damages. In addition to other remedies, Lessor may
recover actual damages incurred.

20.1     LIEN FOR RENT. (a) Notwithstanding anything to the contrary in this
lease, Lessor's landlord lien shall be subordinate to any existing security
interest and any future purchase money security interests on Lessee's personal
property excepting all intellectual property, if such security interest is
properly perfected and timely recorded as required by the Texas Business Code.
Lessor shall cooperate in signing lien subordinations in accordance with the
forgoing. Any lien subordination shall be on forms reasonably acceptable to
Lessor.

                       (b) Subject to the limitations of subparagraph (a) above,
Lessee gives to Lessor a contractual lien on all of Lessee's property which may
be found on the leased premises to secure payment of all monies and damages owed
by Lessee under the lease. Such lien also covers all insurance proceeds on such
property. Lessee shall not remove such property while rent or other sums remain
due and unpaid to Lessor and such property shall not be removed until all
Lessee's obligations under the lease have been complied with. This lien is in
addition to Lessor's statutory lien under Section 54.021 of the Texas Property
Code. If Lessee is in default for nonpayment of rent or any other sums due by
Lessee, Lessor's representatives may peacefully enter the leased premises and
remove and store all property. If Lessor removes any property under this lien,
Lessor shall leave the following information in a conspicuous place inside
Lessee's office space: (1) written notice of exercise of lien, (2) a list of
items removed, (3) the name of Lessor's representative who removed such items,
and (4) the date of such removal. Lessor shall be entitled to reasonable charges
for packing, removing, or storing abandoned or seized property, and may sell
same at public or private sale (subject to any properly recorded chattel
mortgage or recorded financing statement) after 30 days written notice of tie
and place of sale is given to Lessee by certified mail, return receipt
requested. Upon request by Lessor, Lessee shall acknowledge the above lien
rights by executing a UCC-1 form or similar form reflecting same.

21.1     ATTORNEY'S FEES, INTEREST, AND OTHER EXPENSES. If Lessee or Lessor is
in default and if the nondefaulting party places the lease in the hands of an
attorney in order to enforce lease rights or remedies, the nondefaulting party
may recover reasonable attorney's fees from the defaulting party even if suit
has not been filed. In any lawsuit enforcing lease rights, the prevailing party
shall be entitled to recover reasonable attorney's fees from

                                                                         -------

the nonprevailing party, plus all out-of-pocket expenses. Trial shall be to
court only; and all parties waive jury trial. All delinquent sums due by Lessor
or Lessee shall bear interest at the maximum lawful rate of interest, compounded
annually, from date of default until paid, plus any late payment fees. Late
payment fees as set forth in paragraph 3.2 shall be considered reasonable
liquidated damages for the time, trouble, inconvenience, and administrative
overhead expense incurred by Lessor in collecting late rentals, such elements of
damages being uncertain and difficult to ascertain. Late payment fees shall not
be liquidated damages for attorney's fees or for Lessor's loss of use of such
funds during the time of delinquency.

22.1     NONWAIVER. The acceptance of monies past due or the failure to complain
of any action, nonaction, delayed payment, or default, whether singular or
repetitive, shall not constitute a waiver of rights or obligations under the
lease. Lessor's or Lessee's wavier of any right or any default shall not
constitute waiver of other rights, violations, defaults, or subsequent rights,
violations, or defaults under this lease. No act or omission by Lessor or
Lessor's agents shall be deemed an acceptance or surrender of the leased
premises, and no agreement by Lessor to accept a surrender of the leased
premises shall be valid unless it is in writing and signed by a duly authorized
agent of Lessor.

23.1     BUILDING RULES. Lessor's rules for the office building are attached as
Exhibit F-2 and are subject to reasonable change if the changes are applicable
to all tenants of the office building. Separate parking rules are contained in
paragraph F-1. Lessee agrees to provide a copy of the Office Building Rules
(Exhibit F-2) to each of Lessee's employees.

24.1     TRANSFER OF OWNERSHIP BY LESSOR. If Lessor transfers ownership of the
office building (other than as security for a mortgage) and if Lessor has
delivered to the transferee all of Lessee's security deposits and any prepaid
rents, Lessor shall be released from all liability under the lease; and such
transferee shall become liable as Lessor. Such right to be released of liability
shall accrue to subsequent owners only if such transfer is in good faith and for
consideration.

25.1     MORTGAGES. Unless otherwise provided in this lease, Lessee shall
subordinate and attorn to mortgage liens how or hereafter on the office
building. Lessee agrees to execute, from time to time, documentation therefor
which is necessary in the reasonable judgment of Lessor. Other than the
provisions already set forth in this lease, there are no special lease
provisions which are required by lienholders of the office building. This lease
shall be subordinate to all existing and future mortgages. However, such
mortgagees may at any time subordinate their lien to this lease by filing a
subordination notice to the county real property records without necessity of
notice to Lessee. Lessee waives and holds any mortgagee or holder of a security
interest harmless from all claims of Lessee against Lessor arising prior to such
mortgagee succeeding to the Lessor's ownership interest in the property. Since a
Mortgagee Nondisturbance Agreement is contemplated, any foreclosure of such
mortgagee's lien shall not terminate this lease even if such lien is superior to
the lease.

26.1     SURRENDER OF PREMISES. When Lessee moves out, Lessee shall surrender
Lessee's office space in the same condition as on the date of lease commencement
by Lessee (as changed or improved from time to time in accordance with this
lease), less ordinary wear. Removal of property from the leased premises is
subject to paragraph 14.1. Upon surrender, Lessee shall provide Lessor with all
of Lessee's keys, access codes and cards to the Leased Premises and the
combination to all safes and vaults, if any in the Leased Premises.

27.1     HOLDING OVER. If Lessee remains in possession of the leased premises
after the expiration or mutually-agreed termination date of the lease, without
the execution by Lessor and Lessee of a new lease or a renewal or extension of
the lease, then (1) Lessee shall be deemed to be occupying the leased premises
as a tenant-at-sufferance on a daily basis subject to all obligations of the
lease, (2) Lessee shall pay rent for the entire holdover period at the rate of
125% of the then-current rental rate, (3) Lessee shall be subject to all other
remedies of Lessor as provided in paragraph 19.1, (4) Lessee shall indemnify
Lessor and/or prospective tenants for damages, including lost rentals, storage
expenses, and attorney's fees, and (5) at Lessor's sole option, Lessee may
extent the lease term for a period of one month at the then current rental rates
for the office building, as reasonably determined by Lessor, by hand delivering
written notice to Lessee or to Lessee's office space while Lessee is holding
over. Holdover rents shall be immediately due on a daily basis and delinquent
without notice or demand; and the prior written notice and waiting period
requirements of this lease shall not be necessary in order for Lessor to
exercise remedies thereunder.

28.1     SIGNS AND BUILDING NAME. Except for standard suite signage and building
directory listings, there shall be no signs, symbols, or identifying marks on or
in the building, halls, elevators, staircases, entrances, parking areas,
landscape areas, doors, walls, or windows without prior written approval of
Lessor. If the lease term is less than twelve (12) months, the cost of initial
suite signage for Lessee's space and initial directory strips shall be at
Lessee's expense. All signs or lettering shall conform to the sign and lettering
criteria established by Lessor. Unless otherwise stated in the rules, suite
signage and building directory changes shall be done exclusively by Lessor.
Unless otherwise stated in the rules, suite signage and building directory
changes shall be done exclusively by Lessor and at Lessee's expense. Lessor may
remove all unapproved signs without prior notice to Lessee and at Lessee's
expense. Lessor may change the name of the building upon six months' written
notice to Lessee.

28.2     RELOCATION OF LESSEE.

29.1     NOTICES.  Whenever written notice is required or permitted under
this lease, such notice shall be in writing and shall be either (a) hand
delivered personally to the party being notified, (b) hand delivered to or
inside such party's mailing address, or (c) delivered at such party's mailing
address by certified mail, return receipt requested, postage prepaid.  The
mailing address of Lessor shall be the address to which Lessee normally mails or
delivers the monthly rent unless Lessor notifies Lessee of a different address
in writing.  The mailing address of Lessee shall be Lessee's office space under
this lease.  However, if Lessee moves out, it shall be Lessee's last address
known by Lessor.  Hand delivered notice is required only when expressly required
in the lease.  Notice by noncertified mail is sufficient if actually received by
the addressee or an employee or agent of addressee.  The term "notice" shall be
inclusive of notices, billings, requests, and demands.

30.1     ESTOPPEL CERTIFICATE.  From time to time, upon 7 days' prior written
request from Lessor, Lessee shall execute and deliver to Lessor the estoppel
certificate attached as Exhibit G.  The form in Exhibit G may be changed as
reasonably required by a prospective purchaser or lender.  If any statement in
the estoppel certificate form is contrary to the facts existing at the time of
execution of such form, Lessee may correct same before signing.  Reasonable
modifications in the form may be made as requested by a prospective lienholder
or purchaser.  The estoppel certificate may be conclusively relied upon by
Lessor and by any prospective lienholder or purchaser of the leased premises.
If Lessee fails to comply with the foregoing by the end of such 7-day period, it
shall be conclusively presumed that (1) this lease is in full force and effect
without any subleases or assignments and is unamended or modified except for
amendments verified by affidavit of Lessor to the prospective lienholder or
purchaser, (2) no rents, security deposits, or other charges have been prepaid,
(3) the statements contained in the estoppel certificate form (Exhibit G) are
correct, (4) there are no uncured defaults by Lessor, (5) Lessee has no right of
offset or rescission, and (6) any prospective purchaser or lienholder may
conclusively rely on such silence or noncompliance by Lessee and may
conclusively assume no Lessor defaults within the 120 days following Lessee's
receipt of Lessor's request for an estoppel certificate.

31.1     SUCCESSORS.  This lease shall bind and inure to the benefit of the
parties, any guarantors of this lease, and their respective successor and
assigns.

31.2     LEASING AGENT COMMISSIONS.  No leasing commission shall be due by
Lessor to any leasing agent unless in writing. Commission agreements executed by
Lessor shall be binding upon subsequent building owners if the tenant of the
lease in question is in possession at the time of transfer of building
ownership.

32.1     BUILDING OPERATING EXPENSE.  In addition to the monthly base rent in
paragraph 2.1, Lessee shall pay additional rent on a monthly basis, equivalent
to Lessee's prorata share of actual building operating expenses as per Exhibit
C.  Lessee's responsibility for payment of building operating costs shall be
subject to the expense stop referred to in Basic Lease Information #8.
                                           -------------------------- 

 33.1    REPRESENTATIONS AND WARRANTIES BY LESSOR.  Lessor warrants that
Lessor is the sole owner of the land and improvements comprising the office
building and that Lessor has full right to enter into this lease.  Lessor's
duties and warranties are limited to those expressly stated in this lease and
shall not include any implied duties or implied warranties, now or in the
future.  No representations or warranties have been made by Lessor other than
those expressly contained in this lease.

34.1     REPRESENTATIONS AND WARRANTIES BY LESSEE.  Lessee warrants to Lessor
that (1) the financial statements of Lessee heretofore furnished to Lessor are
true and correct to the best of Lessee's knowledge, (2) there has been no
significant adverse change in Lessee's financial condition since the date of the
financial statements, (3) the financial statements fairly represent the
financial condition of Lessee upon those dates and at the time of execution
hereof, (4) there are no delinquent taxes due and unpaid by Lessee, and (5)
Lessee and none of the officers or partners of Lessee (if Lessee is a
corporation or partnership) have ever declared bankruptcy.  Lessee warrants that
Lessee has disclosed in writing to Lessor all lawsuits pending or threatened
against Lessee, and Lessee has made no material misrepresentation or material
omission of facts regarding Lessee's financial condition or business operations.
All financial statements must be dated and signed by Lessee.  Lessee
acknowledges that Lessor has relied on the above information furnished by Lessee
to Lessor and that Lessor would not have entered into this lease otherwise.

35.1     PLACE OF PERFORMANCE.  Unless otherwise expressly stated in this
lease, all obligations under this lease, including payment of rent and other
sums due, shall be performed in the country where the office building is
located, at the address designated from time to time by Lessor.

36.1     MISCELLANEOUS.  This lease contains the entire agreement of the
parties.  NO OTHER WRITTEN OR ORAL PROMISES OR REPRESENTATIONS HAVE BEEN MADE,
AND NONE SHALL BE BINDING.  This lease supersedes and replaces any previous
lease between the parties on Lessee's office space, including any renewals or
extensions thereunder.  Except for reasonable changes in written rules, this
lease shall not be amended or changed except by written instrument, signed by
both Lessor and Lessee.  LESSOR'S AND LESSEE'S  AGENTS DO NOT AND WILL NOT HAVE
                                  ------------                                 
AUTHORITY TO (1) MAKE EXCEPTIONS, CHANGES OR AMENDMENTS TO THIS LEASE, OR
FACTUAL REPRESENTATIONS NOT EXPRESSLY CONTAINED IN THIS LEASE, (2) WAIVE ANY
RIGHT, REQUIREMENT, OR PROVISION OF THIS LEASE, OR (3) RELEASE LESSEE FROM ALL
OR PART OF THIS LEASE, UNLESS SUCH ACTION IS IN WRITING AND SIGNED BY BOTH

under this lease.  Notices, requests, or agreements to, from, or with one of
multiple lessees shall be deemed to be to, from, or with all such Lessees.
Under no circumstances shall Lessor or Lessee be considered an agent of the
other.  Nonsubstantial errors in space footage calculations shall entitle the
parties to correct the rental figures in the lease and adjust rentals previously
paid to present Owner accordingly, but not to terminate the lease.  The lease
shall not be construed against either party more or less favorably by reason of
who drafted the lease or changes in the lease.  Texas law applies.  If any date
of performance or exercise of a right ends on a Saturday, Sunday, or state
holiday, such date shall be automatically extended through the next business
day.  Time is of the essence; and all performance dates, time schedules, and
conditions precedent to exercising a right shall be strictly adhered to without
delay except where otherwise expressly provided.  If any provisions of this
lease is invalid under present or future laws, the remainder of this lease shall
not be affected.

              BUILDING OPERATING EXPENSE PASSTHROUGH CALCULATIONS
                     (see paragraphs 2.1 and 32.1 of lease)


          (a)  "ESTIMATED" PRORATA BUILDING OPERATING EXPENSES. On or before the
               beginning of each calendar year, Lessor shall calculate the
               estimated building operating expenses for that calendar year,
               according to the criteria in subparagraph (c) below. One-twelfth
               of Lessee's prorata share of estimated building operating
               expenses which are in excess of any expense stop shall be due on
               the first of each month as additional rent.

          (b)  YEAR-END ADJUSTMENT FOR OVERPAYMENT OR UNDERPAYMENT BY LESSEE
               BECAUSE OF DIFFERENCES BETWEEN "ESTIMATED" AND "ACTUAL" BUILDING
               OPERATING EXPENSES. After each calendar year of the lease term
               and renewal or extension periods, Lessor shall determine the
               actual building operating expenses for that calendar year (1996
               Operating Expenses are estimated to be $5.75/sf/yr). If it is
               then determined that actual building operating expenses were less
               than estimated expenses and that Lessee's monthly payments of
               estimated expenses over Lessee's expense stop figure were too
               much, Lessor shall promptly credit to Lessee the excess amount
               paid by Lessee. If it is determined that actual building
               operating expenses were more than estimated expenses and that
               Lessee's monthly payments of estimated expenses over Lessee's
               expense stop figure were insufficient, Lessor shall invoice
               Lessee for the amount of Lessee's underpayment. Payment thereof
               shall be due within thirty (30) days upon delivery of invoice to
               Lessee. Payment may be made prior to or with the next scheduled
               rental payment, but not later. The foregoing calculations and
               adjustments may also be made one or more times during the
               calendar year, at Lessor's option. After 1996, the controllable
               expense increases will be capped at six percent (6%) (cumulative)
               per year.

          (c)  DEFINITION OF BUILDING OPERATING EXPENSES. Building operating
               expenses for each calendar year shall include: all ad valorem
               taxes, assessments and related government charges becoming due on
               the building and on-site personal property used in operation of
               the building in such period; utilities; insurance premiums for
               fire, extended coverage, vandalism, and liability on the building
               and personal property used in building management; landscape
               expenses; janitorial expenses; window cleaning; supplies
               painting, roof repairs, window replacement, and other maintenance
               expenses; licenses; permits; advertising; maintenance salaries
               and bonuses; payroll taxes; management office overhead and
               management fees; and all other managerial, administrative and
               operating expenses which are reasonably related to the operation
               of the building and utilities serving same. No such category
               shall include more than 12 months' worth of expenses. Building
               operating expenses shall also include the following improvements
               if amortized over the useful life of such improvements for IRS
               purposes together with interest at 12% per annum on the
               unamortized cost: (i) improvements to reduce operating expenses,
               (ii) improvements required by governmental agencies following
               completion of the building, and (iii) carpeting, floor covering,
               draperies, and wall coverings for the common areas of the
               building. Building operating expenses shall be calculated on an
               accrual basis in accordance with generally accepted accounting
               principles, consistently applied. The word "building" as referred
               to above shall include the building, parking areas, parking
               garage (if any), and common areas.

Building operating expenses shall not include: principal and interest payments
on mortgages; depreciation or improvements which IRS requires to be depreciated
(except as provided above); expenses of repairing damage of the type normally
covered by fire, vandalism, flood, and EC insurance; any expense paid or
reimbursed from insurance proceeds; costs of repairing damage for which Lessor
is entitled to reimbursement from others;

                                                                 Page Two of Two

remodeling costs for new or existing tenants; common area improvements or
personal property required by other tenants to be made, purchased, or furnished
to such tenants; utility and air conditioning or heating costs or other expenses
which are separately billed to specific tenants; franchise and income taxes if
of Lessor; leasing commissions; expenses of marketing vacant space in the
building; legal fees; structural repairs to roof, foundation, and walls;
asbestos removal; and installation of sprinklers, fire alarms, and smoke
detector systems.

If utilities and taxes included in "Building Operating Expense" are not payable,
billed or otherwise due so as to allow an accurate calculation of said factors
annually, then Lessor, in its reasonable discretion, may estimate and prorate
said expenses on an annual basis, and said factors shall be properly adjusted by
Lessor when they actually become due and payable. Otherwise, expenses must be
supported by invoices and actually paid.

        (d)    DEFINITION OF PRORATA SHARE. Lessee's prorate share of estimated
               and actual building operating expenses is the percentage result
               of dividing "Lessee's rentable area" (which is set forth in Basic
                                                                           -----
               Lease Information #4) by the total rentable area in the entire
               --------------------
               building.

        (e)    DELAY IN IMPLEMENTATION. At Lessor's option, adjustments may be
               delayed. Lessor's delay in implementing such adjustments shall
               not waive Lessor's right thereto, and the most recent monthly
               rental figures shall continue to be paid during such delay. If
               Lessor delays in timely calculating adjustments, such adjustments
               shall be retroactive to the respective date on which Lessor had a
               right to make such adjustment; and such delayed rent adjustments
               shall become due upon written notice to Lessee.

        (f)    EXAMINATION OF RECORDS. Upon reasonable notice to lessor in
               writing, lessee may examine or audit Lessor's accounting records
               for building operating expenses for the year immediately
               preceding and other data used in calculating additional rents or
               rent adjustments. Examination or audit of building operating
               expenses for a particular year may be conducted no later than 120
               days after Lessee's receipt of a reconciliation notice or
               statement of building operating expenses for that year. If not
               examined or audited within the 120 day period, such
               reconciliation shall be deemed as accepted and agreed to by all
               parties.

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

Lessee agrees to lease Suite 300 with the following improvements listed (below)
                             ---                                               
or (on the attached floor plan).  The cost for said improvements, including
space planning fees, and construction management fees, shall not exceed
$38,101.00 ($3.50/usf).
- ----------  ---------  

Any modification to the existing improvements shall be applied against the
dollar allowance and improvement costs that exceed the above-referenced
allowance shall be payable by Lessor and repaid by Lessee with the payment
          -------------------
amortized over the term of the lease at nine percent (9%) interest.

If actual costs for capital improvements based on signed construction documents
by Lessee are less than the above-referenced allowance, including space
planning, and construction management fees, the Lessee will not receive a credit
                                                            ---                 
for the unspent portion of the allowance.

Improvements:  Lessor will remove all of the wallpaper and then recarpet and
               paint the entire space, demo up to seven walls, install a shower,
               re-key the locks and install a fixed object to lock one
               motorcycle, or more if within the dollar allowance. Lessee shall
               not be required to pay for (through Operating Expenses or
               otherwise) or make any structural changes or capital expenditures
               in or on the premises in order to comply with any law, ordinance,
               rule or regulation unless the charges or expenditures are
               required by Lessee's particular use of the Premises. Lessee shall
               have no obligation to restore the premises at the end of the
               lease term unless Lessor specifies at the time that the plans are
               originally approved.

It is the desire of Lessor to maintain and operate the parking garage and
parking areas in an orderly manner. The following rules apply to all tenants in
the building and their agents, employees, family, licensees, invitees, visitors,
and contractors unless otherwise stated. Lessor reserves the right to rescind
these rules, make reasonable changes, or make other reasonable rules and
regulations for the safety, care, and cleanliness of the parking garage, if

                             OFFICE BUILDING RULES
                     (see paragraphs 9.2 and 23.1 of lease)

        LESSEE AGREES TO PROVIDE A COPY OF THESE RULES TO EVERY EMPLOYEE

It is the desire of lessor to maintain in the building the highest standard of
dignity and good taste consistent with comfort and convenience for all tenants.
Any action or condition not meeting this high standard should be reported
directly to the building manager. Cooperation by all tenants will be sincerely
appreciated. The following rules and regulations apply to all tenants in the
building and their agents, employees, family, licensees, invitees, visitors, and
contractors unless otherwise stated. Pursuant to paragraph 23.1 of the lease,
Lessor reserves the right to rescind these rules, make reasonable modification
thereto, and make other reasonable rules and regulations for the safety, care,
and cleanliness of the building and for the preservation of good order.

1.   DELIVERIES AND MOVEMENT OF FURNITURE. Movement into or out of the building
     of furniture, equipment shall be restricted to hours, stairways, and
     elevators designated by Lessor. Unless Lessor notifies Lessee otherwise,
     only the freight elevator may be used for such purposes, and such elevator
     may be used only during regular business hours without prior approval of
     Lessor. All such movement and delivery shall be under the supervision of
     the building manager and carried out in a manner agreed between Lessee and
     the building manger, by prearrangement. Prearrangement shall include time,
     method, routing, and any limitations imposed for reasons of safety or
     nondisturbance of others. The hold harmless and indemnification provisions
     of paragraph 12.2 shall apply to the foregoing. Lessor may require that
     movement of furniture or equipment which interferes with normal building
     traffic shall be made at hours other than normal business hours.

2.   OBSTRUCTION OF PASSAGEWAYS. None of the passageways, outside entries,
     exterior doors, elevators, hallways, or stairway shall be locked or
     obstructed. No rubbish, trash, litter, or materials of any nature may be
     emptied or thrown into these areas. These areas may be used only for
     ingress and egress.

3.   DOORS AND DOORLOCKS. When Lessee's corridor doors are not in use, Lessee
     shall use its best efforts to keep them closed on all floors where Lessee
     is a partial tenant on the floor. No additional locks shall be placed on
     any doors in Lessee's office space without written consent of Lessor.
     Lessee shall not change, alter, or replace locks provided by Lessor on
     doors in the building, except with written permission of the building
     manger. All necessary keys shall be furnished by lessor, and lessor shall
     be entitled to have a key for every door in Lessee's office space. Lessee
     shall surrender all keys upon termination of lessee's right of occupancy;
     and at such time, Lessee shall give Lessor the combination to all vaults or
     combination locks remaining in lessee's office space after surrender by
     Lessee.

4.   SAFES. Safes and other heavy articles shall be carried onto the leased
     premises only at such items and in such manner as prescribed by Lessor.
     Lessor shall have the right to specify weight limitations and positioning
     of safes or other heavy articles. Any damage done to the building by
     installation, presence, or removal of a safe or other article owned or
     controlled by Lessee on the leased premises, shall be paid for by Lessee.

6.   installation and repair work. Lessee shall refer all contractors,
     contractors' representatives, and installation technicians who render any
     service on or to Lessee's office space, to the building manager for
     approval and supervision before performance of any service. This provision
     shall apply to all work performed in the building, including installation
     of telephones, electrical lines, and other electrical devices where such
     installation affects the floors, walls, woodwork, trim, windows, ceilings,
     mechanical equipment, or any other part o the building. If Lessee desires
     telephone or other electronic connections, Lessee shall notify Lessor; and
     lessor shall then direct installation servicemen as to where and how wires
     may be introduced. Without such directions, no such installation shall be
     permitted.

     outside their regular duties unless pursuant to special orders from lessor.
     Lessee may not contract with Lessor's employees for the performance of paid
     or free services to Lessee. If, at the request of Lessee, lessor or
     Lessor's agents furnish services, goods, labor, or material to Lessee which

     pay for same upon delivery of a written statement therefor to Lessee.

23.  BUILDING ACCESS. Anyone who does not reasonably satisfy a building security
     guard (if any) that he has a right to enter the building may be excluded by

     with regard to admission or exclusion from the building of any person. In
     case of fire, destruction, invasion, mob, riot, or other commotion, Lessor
     reserves the right to prevent access to the building by closing the doors
     or otherwise.

                         HAZARDOUS MATERIALS STATEMENTS


Various materials utilized in the construction of any improvements to the
property or in the use thereof, past or present, may contain materials that have
been or may in the future be determined to be hazardous.  For example, some
electrical transformers and other electrical components can contain PCBs, and
asbestos may have been used in a wide variety of building components such as
fire-proofing, air duct insulation, acoustical tiles, spray-on acoustical
materials, linoleum floor tiles and plaster.  Such substances may be present on
or in soils, underground water, building components or other portions of the
leased premises in areas that may or may not be accessible or noticeable.

Current federal, state and local laws and regulations may require the clean-up
of such hazardous or undesirable materials.

Lessor, real estate brokers, and leasing agents in this transaction have no
expertise with respect to hazardous materials and have not made, nor will any of
their statements constitute representations, either express or implied,
regarding the existence or nonexistence of hazardous materials in or on the
leased premises.

        Approved by the Texas Real Estate Commission for Voluntary Use

Texas law requires all real estate licensees to give the following information
about brokerage services to prospective buyers, tenants, sellers and landlords

- --------------------------------------------------------------------------------
                     Information About Brokerage Services
 -------------------------------------------------------------------------------

Before working with a real estate broker, you should know that the duties of a
broker depend on whom the broker represents. If you are a prospective seller or
landlord (owner) or a prospective buyer or tenant (buyer), you should know that
the broker who lists the property for sale or lease is the owner's agent. A
broker who acts as a subagent represents the owner in cooperation with the
listing broker. A broker who acts as a buyer's agent represents the buyer. A
broker may act as an immediary between the parties if the parties consent in
writing. A broker can assist you in locating a property, preparing a contract or
lease, or obtaining financing without representing you, a broker is obligated by
law to treat you honestly.

IF THE BROKER REPRESENTS THE OWNER: The broker becomes the owner's agent by
entering into an agreement with the owner, usually through a written listing
agreement, or by agreeing to act as an subagent by accepting an offer of
subagency from the listing broker. A subagent may work in a different real
estate office. A listing broker or subagent can assist the buyer but does not
represent the buyer and must place the interests of the owner first. The buyer
should not tell the owner's agent anything the buyer would not want the owner to
know because an owner's agent must disclose to the owner any material
information known to the agent.

IF THE BROKER REPRESENTS THE BUYER: The broker becomes the buyer's agent by
entering into an agreement to represent the buyer, usually through a written
buyer representation agreement. A buyer's agent can assist the owner but does
not represent the owner and must place the interests of the buyer first. The
owner should not tell a buyer's agent anything the owner would not want the
buyer to know because a buyer's agent must disclose to the buyer any material
information known to the agent.

IF THE BROKER ACTS AS AN INTERMEDIARY: A broker may act as an intermediary
between the parties if the broker complies with The Texas Real Estate License
Act. The broker must obtain the written consent of each party to the transaction
to act as an intermediary. The written consent must state who will pay the
broker and, in conspicuous bold or underlined print, set forth the broker's
obligations as a intermediary. The broker is required to treat each party
honestly and fairly and comply with The Texas Real Estate License Act. A broker
who cast as an intermediary in a transaction:

  (1)  shall treat all parties honestly;
  (2)  may not disclose that the owner will accept a price less than the asking
   price unless authorized in writing to do so by the owner;
  (3)  may not disclose that the buyer will pay a price greater than the price
   submitted in a written offer unless authorized in writing to do so by the
   buyer; and
  (4)  may not disclose any confidential information or any information that a
   party specifically instructs the broker in writing not to disclose unless
   authorized in writing to disclose the information or required to do so by The
   Texas Real Estate License Act or a court order or if the information
   materially relates to the condition of the property.

With the parties' consent, a broker acting as an intermediary between the
parties may appoint a person who is licensed under The Texas Real Estate License
Act and associated with the broker to communicate with and carry out instruction
so one party and another person who is licensed under that Act and associated
with the broker to communicate with an carry out instruction of the other party.

If you choose to have a broker represent you, you should enter into a written
agreement with the broker that clearly establishes the broker's obligations and
your obligations. The agreement should state how and by whom the broker will be
paid. You have the right to choose the type of representation, if any, you wish
to receive. Your payment of a fee to a broker does not necessarily

                                RENEWAL OPTION


At the end of the original lease term, Lessee shall have the right to renew this
lease for a period of thirty-six (36) months provided that Lessee delivers to
Lessor written notice of Lessee's intent to renew at least three (3) months
prior to the end of the lease term.  However, Lessee shall not have such right
of renewal if Lessee is in default as defined in paragraph 19.1 (a) either at
the time of such notice of renewal or at the end of the lease term.  The terms
of this lease during such renewal term shall continue except as follows:

Lessee's base rate shall adjust to the then current market rate and conditions
for like and similar space.

"Then current market terms and conditions" shall mean those terms and conditions
prevailing on the renewal deadline date for comparable space in One Far West
Plaza to tenants or prospective tenants of comparable creditworthiness.  If on

                            RIGHT OF FIRST REFUSAL


So long as Lessee is not in default under the lease, as set forth in paragraph
19.1, Lessee will have a reoccurring "Right of First Refusal" on all of the
rentable square feet located on the third floor.  In cases where an existing
tenant already has a right of first refusal or other options at the time of
lease execution, Lessee will have the second right.  Lessee will have five (5)
business days upon lessee's receipt of written notice of a firm offer (with copy
of the offer included) to accept or reject the space on the same terms and
conditions as lessor is prepared to enter into by a lease with a third party,
except that the space will be coterminous with lessee's primary space.  The
finish-out allowance will be modified on a pro rata basis based on the length of
the lease that lessee has remaining.  Lessee has the right to amortize the
entire amount of the tenant finish-out allowance offered to the prospect by
amortizing at a nine percent (9%) discount rate the difference in the total
amount and the pro rata portion.

       adjusted pursuant to Section 3 of the Work Letter).

SECTION 1.2   INSPECTION AND DELIVERY OF PREMISES, CONSTRUCTION OF LEASE SPACE
IMPROVEMENTS AND POSSESSION.

1.201  Delivery.  Tenant acknowledges that Tenant has inspected the Premises and
       --------

       discovered and reported to Landlord by Tenant within 180 days from the
       Commencement Date, hereby (i) accepts the Common Areas in "as is"
       condition for all purposes and (ii) subject to Landlord's completion of
       its obligations under the Work Letter, Tenant hereby accepts the Premises
       (including the suitability of the Premises for the Permitted Use) for all
       purposes.

1.202  Completion.  Landlord will perform or cause to be performed the work
       ----------                                                          
       and/or construction of Tenant's Improvements (as defined in the Work
       Letter) in accordance with the terms of the Work Letter and will use

       Letter) Tenant's Improvements by the Commencement Date. If Tenant's
       Improvements are not Substantially Complete by the Commencement Date set
       forth in Item 6 of the Basic Lease Provisions for any reason whatsoever,
       Tenant's sole remedy shall be an adjustment of the Commencement Date and
       the Expiration Date to the extent permitted under Section 3 of the Work
       Letter.

1.203  Acceptance of Premises Memorandum.  Upon Substantial Completion (as
       ---------------------------------                                  
       defined in the Work Letter) of Tenant's Improvements, Landlord and Tenant
       shall execute the Acceptance of Premises Memorandum (herein so called)
       attached hereto as Exhibit E. If Tenant occupies the Premises without
                          ---------
       executing an Acceptance of Premises Memorandum, Tenant shall be deemed to
       have accepted the Premises for all purposes and Substantial Completion
       shall be deemed to have occurred on the earlier to occur of (i) actual
       occupancy or (ii) the Commencement Date set forth in Item 6 of the Basic
       Lease Provisions.

SECTION 1.3   REDELIVERY OF THE PREMISES.

1.301  Obligation to Redeliver.  Upon the expiration or earlier termination of
       -----------------------                                                
       this Lease or upon the exercise by Landlord of its right to re-enter the
       Premises without terminating this Lease, Tenant shall immediately deliver
       to Landlord the Premises free of offensive odors and in a safe, clean,
       neat, sanitary and operational condition, together with all keys and
       parking and access cards. Tenant shall, by the Expiration Date or, if
       this Lease is earlier terminated, within seven (7) days after the
       termination, at the sole expense of Tenant: (i) remove from the Premises
       (unless Landlord is asserting its lien rights therein) any equipment,
       machinery, trade fixtures and personalty installed or placed in the
       Premises by or on behalf of Tenant and (ii) if requested by Landlord, (a)
       remove from the Premises all or any part of the improvements (other than
       Tenant's Improvements and other improvements approved by Landlord without
       the requirement that same be removed upon expiration or earlier
       termination of the Lease) made to the Premises by or on behalf of Tenant
       and (b) restore the Premises to the condition existing immediately prior
       to the installation of such improvements. All removals and work described
       above shall be accomplished in a good and workmanlike manner and shall be
       conducted so as not to damage the Premises or the Building or the
       plumbing, electrical lines or other utilities serving the Building.
       Tenant shall, at its expense, promptly repair any damage caused by any
       such removal or work. If Tenant fails to deliver the Premises in the
       condition aforesaid, then Landlord may restore the Premises to such a
       condition at Tenant's expense. All property required to be removed
       pursuant to this Section not removed within time period required
       hereunder shall thereupon be conclusively presumed to have been abandoned
       by Tenant and Landlord may, at its option, take over possession of such
       property and either (a) declare the same to be the property of Landlord
       by written notice to Tenant at the address provided herein or (b) at the
       sole cost and expense of Tenant, remove and store and/or dispose of the
       same or any part thereof in any manner that Landlord shall choose without
       incurring liability to Tenant or any other person.

1.302  Failure to Deliver.  Notwithstanding any provision or inference to the
       ------------------                                                    
       contrary herein contained, in the event that Tenant fails to deliver to
       Landlord (and surrender possession of) all of the Premises upon the
       expiration or earlier termination of this Lease 

                                      -1-
<PAGE>
 
       (or the applicable portion of the Premises if this Lease expires or
       terminates as to only a portion of the Premises) on the date of
       expiration or earlier termination, then Landlord may, without judicial
       process and without notice of any kind, immediately enter upon and take
       absolute possession of the Premises or applicable portion thereof, expel
       or remove Tenant and any other person or entity who may be occupying the
       Premises or applicable portion thereof, change the locks to the Premises
       or applicable portion thereof (in which event, Tenant shall have no right
       to any key for the new locks), limit elevator access to the Premises or
       applicable portion thereof, and take any other actions as are necessary
       for Landlord to take absolute possession of the Premises or applicable
       portion thereof. The foregoing rights are without prejudice and in
       addition to, and shall not in any way limit Landlord's rights under,
       Section 1.4 below.

SECTION 1.4   HOLDING OVER.  In the event Tenant or any party under Tenant
claiming rights to this Lease, retains possession of the Premises after the
expiration or earlier termination of this Lease, such possession shall
constitute and be construed as a tenancy at will only, subject, however, to all
of the terms, provisions, covenants and agreements on the part of Tenant
hereunder; such parties shall be subject to immediate eviction and removal and
Tenant or any such party shall pay Landlord as rent for the period of such
holdover an amount equal to one and one-half (1-1/2) times the Basic Annual Rent
and Additional Rent (as hereinafter defined) in effect immediately preceding
expiration or termination, as applicable, prorated on a daily basis.  Tenant
shall also pay actual damages sustained by Landlord by reason of Tenant's
holding over after the Required Vacancy Date (hereinafter defined); provided
that Tenant shall be liable for lost profits and/or penalties incurred by
Landlord in connection with a lease of the Premises to a third party  as a
result of Tenant's holding over only if Landlord gives a written notice to
Tenant (i) stating that Landlord has entered into a lease with a proposed tenant
covering the Premises or a portion thereof and, if less than the entire
Premises, identifying the portion of the Premises leased, and (ii) setting forth
a date (the "Required Vacancy Date") on which Landlord requires Tenant to vacate
the Premises, which date shall be no earlier than the later to occur of (i)
thirty (30) days after Tenant's receipt of Landlord's notice, or (ii) the
Expiration Date, and Tenant fails to vacate the Premises (or the portion thereof
subject to a third-party lease) on or before the Required Vacancy Date.  The
rent during such holdover period shall be payable to Landlord from time to time
on demand; provided, however, if no demand is made during a particular month,
holdover rent accruing during such month shall be paid in accordance with the
provisions of Article 2.  Tenant will vacate the Premises and deliver same to
Landlord immediately upon Tenant's receipt of notice from Landlord to so vacate.
No holding over by Tenant, whether with or without consent of Landlord, shall
operate to extend the term of this Lease; no payments of money by Tenant to
Landlord after the expiration or earlier termination of this Lease shall
reinstate, continue or extend the term of this Lease; and no extension of this
Lease after the expiration or earlier termination thereof shall be valid unless
and until the same shall be reduced to writing and signed by both Landlord and
Tenant.  If Landlord elects to cause Tenant to be ejected from the Premises
through judicial process, and without in any way limiting Landlord's rights
under subsection 1.302 above, Tenant agrees that Landlord will not be required
to deliver Tenant more than one (1) days' notice to vacate prior to Landlord's
filing of a forcible detainer suit.  In addition, Tenant agrees that Landlord
shall be entitled to the payment of its reasonable legal fees in the event that
Landlord prevails in a forcible detainer action brought by Landlord.

                                   ARTICLE 2

advance, without demand, offset or deduction, which monthly installments shall
commence on the Commencement Date and shall continue on the first (1st) day of
each calendar month thereafter.  If the Commencement Date occurs on a day other

        Commencement Date to, the provisions of Tex. Rev. Civ. Stat. Ann. art.
        9102 and the provisions of the Americans With Disabilities Act of 1990,
        42 U.S.C. (S)(S)12101-12213 (collectively, the "Disability Acts"),
        amortized over such period as Landlord shall reasonably determine,
        together with an amount equal to interest at the Amortization Rate on
        the unamortized balance thereof; (iii) the cost of any labor-saving or
        energy-saving device or other equipment installed in the Building
        (provided Landlord reasonably anticipates that the installation thereof
        will reduce Operating Expenses), amortized over such period as is
        reasonably determined by Landlord, together with an amount equal to
        interest at the Amortization Rate on the unamortized balance thereof;
        and (iv) all other capital costs and expenses which would generally be
        regarded as ownership, operating, maintenance and management costs and
        expenses which would normally be amortized over a period not to exceed
        two (2) years.

        Notwithstanding any contrary provision in subsection 2.201 of the
        Supplemental Lease Provisions, "Operating Expenses" shall not include
        any of the following: costs for which Landlord actually receives
        reimbursement by insurance, condemnation awards, warranties or
        otherwise, including direct reimbursements by Tenant or other tenants on
        the Property (other than through a pass-through of Operating Expenses);
        that portion of any payment made to an affiliate of Landlord that is in
        excess of the amount which would have been paid in the absence of such
        relationship and accounting and legal fees incurred as a part of
        Landlord's general corporate or partnership overhead.

2.202   Gross-Up.  Operating Expenses shall be grossed up to include all
        --------                                                        
        additional costs and expenses of owning, operating, maintaining and
        managing the Building which Landlord determines that it would have
        incurred, paid or been obligated to pay during such year if the Building
        had been one hundred percent (100%) occupied.

2.203   Payment Obligation.  In addition to the Basic Rent specified in this
        ------------------                                                  
        Lease, Tenant shall pay to Landlord the Additional Rent, in each
        calendar year or partial calendar year during the term of this Lease,
        payable in monthly installments as hereinafter provided. Tenant's
        initial monthly installment of Additional Rent is set forth in Item 4.b
        of the Basic Lease Provisions. On or prior to the Commencement Date and
        at least thirty (30) days prior to each calendar year thereafter (or as
        soon thereafter as is reasonably possible), Landlord shall give Tenant
        written notice of Tenant's estimated Additional Rent for the applicable
        calendar year and the amount of the monthly installment due for each
        month during such year. Tenant shall pay to Landlord on the Commencement
        Date and on the first day of each month thereafter the amount of the
        applicable monthly installment, without demand, offset or deduction,
        provided, however, if the applicable installment covers a partial month,
        then such installment shall be prorated on a daily basis. Within ninety
        (90) days after the end of (i) each calendar year and (ii) the
        Expiration Date or as soon thereafter as is reasonably possible,
        Landlord shall prepare and deliver to Tenant a statement showing
        Tenant's actual Additional Rent for the applicable calendar year,
        provided that with respect to the calendar year in which the Expiration
        Date occurs, (x) that calendar year shall be deemed to have commenced on
        January 1 of that year and ended on the Expiration Date (the "Final
        Calendar Year") and (y) Landlord shall have the right to estimate the
        actual Operating Expenses allocable to the Final Calendar Year but which
        are not determinable within such ninety day period. If Tenant's total
        monthly payments of Additional Rent for the applicable year are less
        than Tenant's actual Additional Rent, then Tenant shall pay to Landlord
        the amount of such underpayment. If Tenant's total monthly payments of
        Additional Rent for the applicable year are more than Tenant's actual
        Additional Rent, then Landlord shall credit against the next Additional
        Rent payment or payments due from Tenant the amount of such overpayment,
        provided, however, with respect to the Final Calendar Year, Landlord
        shall pay to Tenant the amount of such excess payments, less any amounts
        then owed to Landlord. Unless Tenant takes written exception to any item
        within thirty (30) days after the furnishing of an annual statement,
        such statement shall be considered as final and accepted by Tenant. Any
        amount due Landlord as shown on any such statement shall be paid by
        Tenant within thirty (30) days after it is furnished to Tenant.

2.204   Billing Disputes.  If there exists any dispute as to (i) the amount of
        ----------------                                                      
        Additional Rent, (ii) whether a particular expense is properly included
        in Additional Rent or (iii) Landlord's calculation of Additional Rent
        (each an "Additional Rent Dispute"), the events, errors, acts or
        omissions giving rise to such Additional Rent Dispute shall not
        constitute a breach or default by Landlord under this Lease and even if
        a judgment resolving the Additional Rent Dispute is entered against
        Landlord, this Lease shall remain in full force and effect and Landlord
        shall not be liable for any consequential damages resulting from the
        event, error, act or omission giving rise to such Additional Rent
        Dispute. Notwithstanding the existence of an Additional Rent Dispute,
        Tenant shall pay timely the amount of Additional Rent which is in
        dispute and will continue to make all subsequent payments of Additional
        Rent as and when required under this Lease, provided that the payment of
        such disputed amount and other amounts shall be without prejudice to
        Tenant's position. If an Additional Rent is resolved in favor of Tenant,
        Landlord shall forthwith pay to Tenant the amount of Tenant's
        overpayment of Additional Rent, together with interest from the time of
        such overpayment at the annual rate of ten percent (10%).

2.205   Revisions in Estimated Additional Rent.  If Real Estate Taxes, Insurance
        --------------------------------------                                  
        Premiums, Utility Expenses or Additional Pass Through Costs increase
        during a calendar year or if the number of square feet of rentable area
        in the Premises increases, Landlord may revise the estimated Additional
        Rent during such year by giving Tenant written notice to that effect and
        thereafter Tenant shall pay to Landlord, in each of the remaining months
        of such year, an additional amount equal to the amount of such increase
        in the estimated Additional Rent divided by the number of months
        remaining in such year.

2.206   Real Estate Tax Protest.  Section 41.413 of the Texas Property Tax Code
        -----------------------                                                
        may give Tenant the right to protest before the appropriate appraisal
        review board a determination of the appraised value of the Property if
        Landlord does not so protest and requires Landlord to deliver to Tenant
        a notice of any determination of the appraised value of the Property.
        Tenant acknowledges that the Property is a multi-tenant facility, that
        any filing of a protest of appraised value by Tenant will give the
        appraisal district discretion to increase or decrease the appraised
        value, that an increase in the appraised value will affect Landlord and
        the other tenants of the Property, and that an increase in the appraised
        value may increase the taxes not only for the year in question but for
        future years, potentially beyond expiration of the Lease Term.
        Accordingly, to the extent permitted by applicable law, Tenant hereby
        waives the provisions of (S)41.413 of the Texas Property Tax Code (or
        ------
        any successor thereto). In the alternative, if (S)41.413 of the Texas
        Property Tax Code may not be waived, Tenant agrees not to protest any
        valuation unless Tenant notifies Landlord in writing of Tenant's intent
        so to protest and Landlord fails to protest the valuation within fifteen
        (15) days after Landlord receives Tenant's written notice. If Tenant
        files a protest without giving the written notice required by the
        preceding sentence, such filing shall be an event of default under this
        Lease without the necessity of any notice from Landlord, regardless of
        the provisions of Section 13.102 of this Lease. Furthermore, if Tenant
        exercises the right of protest granted by (S)41.413 of the Texas
        Property Tax Code, Tenant shall be solely responsible for, and shall
        pay, all costs of such protest. If as a result of any protest filed by
        Tenant, the appraised value of the Property is increased by the
                                                       ---------
        appraisal board, Tenant shall be solely responsible for, and shall pay
        upon demand by Landlord, all taxes (not only Tenant's Pro Rata Share
        Percentage of Real Estate Taxes) assessed against the Property in excess
        of the taxes which would have been payable in the absence of the
        protest. Tenant shall continue to pay such excess taxes until the
        determination of appraised value of the Property is changed by the
        appraisal review board, REGARDLESS OF WHETHER THE INCREASED TAXES ARE
        INCURRED DURING THE TERM OF THE LEASE OR THEREAFTER. Landlord agrees,
        upon request by Tenant, to provide to Tenant a copy of the determination
        of appraised value for any year. The payment obligations of Tenant under
        this Section 2.206 shall survive the expiration or other termination of
        this Lease. Each calendar year during the Term of this Lease, Landlord
        agrees to engage a real estate tax consultant for purposes of evaluating
        whether or not to protest Real Estate Taxes and in the event such
        consultant recommends that Landlord protest Real Estate Taxes for any
        particular calendar year, Landlord will follow such recommendation
        unless Landlord obtains Tenant's consent to act otherwise.

SECTION 2.3   RENT DEFINED AND NO OFFSETS.  Basic Annual Rent, Additional Rent
and all other sums (whether or not expressly designated as rent) required to be
paid to Landlord by Tenant under this Lease (including, without limitation, any
sums payable to Landlord under any addendum, exhibit, rider or schedule attached
hereto) shall constitute rent and are sometimes collectively referred to as
"Rent".  Each payment of Rent shall be paid by Tenant when due, without prior
demand therefor and without deduction or setoff.

SECTION 2.4   LATE CHARGES.  If any installment of Basic Annual Rent or
Additional Rent or any other payment of Rent under this Lease shall not be paid
within five (5) days after such payment is  due, a "Late Charge" of five cents
($.05) per dollar so overdue may be charged by Landlord to defray Landlord's
administrative expense incident to the handling of such overdue payments;
provided that Landlord shall not charge a Late Charge for the first (1st) late
payment, if any, made by Tenant during each calendar year of the Lease Term.
Each Late Charge shall be payable on demand.

                                   ARTICLE 3
                                SECURITY DEPOSIT

Tenant will pay Landlord on the date this Lease is executed by Tenant the
Security Deposit set forth in Item 8 of the Basic Lease Provisions as security
for the performance of the terms hereof by Tenant.  Tenant shall not be entitled
to interest thereon and Landlord may commingle such Security Deposit with any
other funds of Landlord.  The Security Deposit shall not be considered an
advance payment of rental or a measure of Landlord's damages in case of default
by Tenant.  If Tenant defaults with respect to any provision of this Lease,
Landlord may, but shall not be required to, from time to time, without prejudice
to any other remedy, 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 other loss
or damage which Landlord may suffer by reason of Tenant's default, including,
without limitation, costs and attorneys' fees incurred by Landlord to recover
possession of the Premises.  If Tenant shall fully and faithfully perform every
material provision of this Lease to be performed by it, the Security Deposit
shall be returned to Tenant within thirty (30) days after the Expiration Date.
Tenant agrees that it will not assign or encumber or attempt to assign or
encumber the monies deposited herein as the Security Deposit and that Landlord
and its successors and assigns shall not be bound by any such actual or
attempted assignment or encumbrance.  Regardless of any assignment of this Lease
by Tenant, Landlord may return the Security Deposit to the original Tenant, in
the absence of evidence satisfactory to Landlord of an assignment of the right
to receive the Security Deposit or any part of the balance thereof.   In the
alternative to a cash Security Deposit, contemporaneously with the execution  of
this Lease, Tenant shall cause an American bank or financial institution located
in Austin, Texas reasonably acceptable to Landlord to issue an irrevocable
letter of credit in the amount of the Security Deposit set forth in Item 8 of
the Basic Lease Provisions (the "Letter of Credit"), naming Landlord as
beneficiary to partially secure the performance of Tenant under the Lease.  The
Letter of Credit shall be for a term of not less than twelve (12) months.  If
all or any portion of the Letter of Credit is drawn against by Landlord, Tenant
shall within thirty (30) days after demand by Landlord, order the issuer of the
Letter of Credit to issue to Landlord at Tenant's expense replacement or
supplementary Letters of Credit such that at all times during the term of this
Lease (other than such thirty (30) day period), Landlord shall have the ability
to draw on one or more Letters of Credit totaling the Security Deposit amount
set forth in Item 8 of the Basic Lease Provisions.  Landlord shall be entitled
to draw on the Letter of Credit one or more times for the reasons and uses
provided above applicable to the Security Deposit. Any amount drawn by Landlord
shall not be deemed to fix or determine the amounts to which Landlord is
entitled under this Lease or otherwise, and Landlord shall be entitled to pursue
any remedies provided for in this Lease to the extent Landlord is unable or
elects, in its sole and absolute discretion, not to obtain complete or partial
satisfaction by drawing upon the Letter of Credit.  Tenant shall cause the
issuance of a replacement Letter of Credit at least thirty (30) days prior to
the expiration date of the then issued Letter of Credit (such date, the
"Reissuance Date").  If Tenant fails to cause the issuance of a replacement
Letter of Credit prior to the Reissuance Date, then Landlord shall have the
right to draw the full amount of the then issued and outstanding Letter of
Credit; provided that such drawing shall not be an Event of Default hereunder
and Landlord shall hold such funds as security for the performance of Tenant's
obligations under this Lease.  Landlord shall refund such funds to Tenant upon
the earlier to occur of (i) Tenant's delivery of a replacement Letter of Credit
and (ii) sixty (60) days after the expiration of this Lease and satisfaction of
Tenant's obligations hereunder.  If the issuer of the Letter of Credit shall
admit in writing its inability to pay its debts generally as they become due,
shall file a petition in bankruptcy 

                                      -4-
<PAGE>
 
or a petition to take advantage of any insolvency act, shall consent to the
appointment of a receiver or conservator of itself or the whole or any
substantial part of its property, shall file a petition or answer seeking
reorganization or arrangement under the United States Bankruptcy Code, shall
have a receiver or conservator appointed or shall become subject to operational
supervision by any Federal or State regulatory authority, then Tenant within
thirty (30) days after written demand by Landlord shall obtain a replacement
Letter of Credit from another financial institution satisfactory to Landlord, in
its reasonable judgment. The rights of Landlord under this provision and any
outstanding Letter of Credit under this Lease (including any assignee under a
collateral assignment of Landlord's rights under this Lease) or any Letter of
Credit and the term "Beneficiary" as used in connection with a Letter of Credit
shall refer to Landlord and to each successor and assign of all or any portion
of Landlord's interest under the Lease.

                               OCCUPANCY AND USE

SECTION 4.1   USE OF PREMISES.

4.101  General.  The Premises shall, subject to the remaining provisions of this
       -------                                                                  
       Section, be used solely for the Permitted Use (herein so called)
       specified in Item 10 of the Basic Lease Provisions. Without in any way
       limiting the foregoing, Tenant will not use, occupy or permit the use or
       occupancy of the Premises for any purpose (and the Permitted Use shall
       not include any use) which is forbidden by or in violation of any law,
       ordinance or governmental or municipal regulation, order, or certificate
       of occupancy, or which may be dangerous to life, limb or property; or
       permit the maintenance of any public or private nuisance; or do or permit
       any other thing which may disturb the quiet enjoyment of any other tenant
       of the Property; or keep any substance or carry on or permit any
       operation which might emit offensive odors or conditions from the
       Premises; or commit or suffer or permit any waste in or upon the
       Premises; or sell or permit the sale of food in any form by or to any of
       Tenant's agents or employees or other parties in the Premises except
       through vending machines in employee lunch or rest areas within the
       Premises for use by Tenant's employees only; or use any apparatus which
       might make undue noise or set up vibrations in the Building; or permit
       anything to be done which would increase the fire and extended coverage
       insurance rate on the Building or Building contents and, if there is any
       increase in such rate by reason of acts of Tenant, then Tenant agrees to
       pay such increase upon demand therefor by Landlord. Payment by Tenant of
       any such rate increase shall not be a waiver of Tenant's duty to comply
       herewith. Notwithstanding the foregoing, Tenant and its employees shall
       be permitted to use microwave ovens and related food service facilities
       in kitchen areas on each floor of the Premises. Further, Tenant shall be
       entitled to have food delivered to the Premises from outside vendors for
       Tenant's employees and its guests. Tenant shall keep the Premises neat
       and clean at all times. Tenant shall comply with, and promptly correct
       any violation of, each and every governmental law, rule or regulation
       relating to the Premises. Tenant shall comply with any direction of any
       governmental authority having jurisdiction which imposes any duty upon
       Tenant or Landlord with respect to the Premises or with respect to the
       occupancy or use thereof.

4.102  Hazardous and Toxic Materials.
       ----------------------------- 

       (a) For purposes of this Lease, hazardous or toxic materials shall mean
       asbestos containing materials ("ACM") and all other materials,
       substances, wastes and chemicals classified as hazardous or toxic
       substances, materials, wastes or chemicals under then-current applicable
       governmental laws, rules or regulations or that are subject to any right-
       to-know laws or requirements.

       (b) Tenant shall not knowingly incorporate into, or use or otherwise
       place or dispose of any hazardous or toxic materials at or on the
       Premises or the Property except for use and storage of cleaning and
       office supplies used in the ordinary course of Tenant's business and then
       only if (i) such materials are in small quantities, properly labeled and
       contained, (ii) such materials are handled and disposed of in accordance
       with the highest accepted industry standards for safety, storage, use and
       disposal, (iii) notice of and a copy of the current material safety data
       sheet is provided to Landlord for each such hazardous or toxic material
       and (iv) such materials are used, transported, stored, handled and
       disposed of in accordance with all applicable governmental laws, rules
       and regulations. Landlord shall have the right to periodically inspect,
       take samples for testing and otherwise investigate the Premises for the
       presence of hazardous or toxic materials. Landlord shall not knowingly
       dispose of any hazardous or toxic materials on the Property and shall
       otherwise deal with all hazardous or toxic materials at the Property in a
       manner that will not materially and adversely affect Tenant's access, use
       or occupancy of the Premises. If Landlord or Tenant ever has knowledge of
       the presence of hazardous or toxic materials on the Property that affect
       the Premises, the party having knowledge shall notify the other party
       thereof in writing promptly after obtaining such knowledge.

       (c) Prior to commencement of any tenant finish work to be performed by
       Landlord, Tenant shall have the right to make such studies and
       investigations and conduct such tests and surveys of the Premises from an
       environmental standpoint as permitted under Rider H-1 attached hereto. If
       Tenant requests that Landlord commence construction of Tenant's
       Improvements prior to exercising such right, Tenant shall be deemed to
       have waived the termination right set forth in Rider H-1.
                                                      --------- 

      (d) If Tenant or its employees, agents or contractors shall ever violate
      the provisions of paragraph (b) of this subsection 4.102 or otherwise
      contaminate the Premises or the Property with hazardous or toxic
      materials, then Tenant shall clean-up, remove and dispose of the material
      causing the violation, in compliance with all applicable governmental
      standards, laws, rules and regulations and then prevalent industry
      practice and standards and shall repair any damage to the Premises or
      Building within such period of time as may be reasonable under the
      circumstances after written notice by Landlord.  Tenant shall notify
      Landlord of its method, time and procedure for any clean-up or removal and
      Landlord shall have the right to require reasonable changes in such
      method, time or procedure or to require the same to be done after normal
      business hours.  Tenant's obligations under this subsection 4.102(d) shall
      survive the termination of this Lease.  Tenant represents to Landlord
      that, except as has been disclosed to Landlord, Tenant has never been
      cited for or convicted of any hazardous or toxic materials violations
      under applicable laws, rules or regulations.

       Premises, (ii) any improvements constructed within the Building by or on

5.103  Electricity.
       ----------- 

       (a) Landlord shall furnish to the Premises electric current not in excess
       of that required by the office lighting and receptacles included in
       Tenant's Improvements, provided, however, Tenant shall be solely
       responsible for the costs of electrical consumption (without duplication)
       in excess of 2 1/2 watts per usable square foot in the Premises connected
       load in respect of office lighting and in excess of 1 1/2 watts per
       usable square foot in the Premises connected load in respect of the power
       outlets therein, at any one time (such consumption is herein referred to
       as "Excess Consumption" and the costs of Excess Consumption are herein
       referred to as "Excess Consumption Costs").

       (b) Landlord may, from time to time, engage a reputable consultant to
       conduct a survey of electrical usage within the Premises or install one
       or more submeters to measure electrical usage within the Premises or a
       particular floor of the Premises. If the survey or submeters reflect
       Excess Consumption, then (i) Tenant shall be responsible for the costs of
       any such surveys and submeters, (ii) Landlord shall have the right to
       install permanent submeters to measure the electrical consumption within
       the Premises (which permanent submeters shall constitute a part of
       Tenant's Submeters, as hereinafter defined), (iii) Tenant shall pay for
       the cost of acquiring, maintaining, repairing and reading such submeters,
       and (iv) Tenant shall pay the Excess Consumption Costs.

       (c) Tenant shall not (i) without the express prior written consent of
       Landlord, permit the consumption in the Premises of more than 2 1/2 watts
       per usable square foot in the Premises connected load in respect of
       office lighting or of more than 1 1/2 watts per usable square foot in the
       Premises connected load in respect of the power outlets therein, at any
       one time, (ii) use electric current in excess of the capacity of the
       feeders or lines to the Building as of the Commencement Date or the
       risers or wiring installation of the Building or the Premises as of the
       Commencement Date, or (iii) install any electrical plugs, connections or
       outlets which supply a voltage greater than 120 volts single phase
       without first notifying Landlord and arranging for the installation of a
       permanent submeter (which shall be deemed to be part of Tenant's
       Submeters), at Tenant's expense, to measure the electrical power consumed
       by the equipment and/or machinery hooked or plugged into such plugs,
       connections or outlets. All submeters installed by Landlord or Tenant to
       measure electrical usage by certain pieces of equipment located within
       the Premises together with any submeters installed by Landlord pursuant
       to paragraph (b) of this subsection are herein collectively referred to
       as "Tenant's Submeters". Landlord will maintain and repair Tenant's
       Submeters, at Tenant's cost.

       (d) Upon the installation of Tenant's Submeters, Landlord will, at
       Tenant's cost, on or about the first day of each month during the Term of
       this Lease, read Tenant's Submeters and record such readings for purposes
       of determining Metered Electrical Expenses (hereinafter defined). The
       cost of electricity consumed within each separately metered portion of
       the Premises and by each separately metered piece of equipment within the
       Premises ("Metered Electrical Expenses") shall be equal to the sum of (i)
       the kilowatts of electricity consumed within the separately metered
       portions of the Premises (as measured by the applicable Tenant's
       Submeters) during the applicable month (or other applicable period) and
       (ii) the kilowatts of electricity consumed by each separately metered
       equipment within the Premises (as measured by the applicable Tenant's
       Submeters), MULTIPLIED BY (iii) the cost per kilowatt of electricity
                   -------------
       charged to Landlord by the public utility for electricity consumed within
       the Building during the applicable month (or other applicable period).
       Landlord may, from time to time, invoice Tenant for Metered Electrical
       Expenses (as well as any Excess Consumption Costs determined by a
       reputable consultant) and Tenant shall, within ten (10) days after
       receiving an invoice therefor, pay Landlord the amount of the Metered
       Electrical Expenses (and/or, as applicable, any Excess Consumption Costs
       determined by a reputable consultant) covered by such invoice. Each such
       invoice submitted by Landlord to Tenant shall include (i) the period of
       consumption covered by such invoice, (ii) the beginning and ending
       readings for each of Tenant's Submeters for such period, (iii) Landlord's
       calculations of the Metered Electrical Expenses covered by such invoice,
       and (iv) if applicable, the independent electrical consultant's
       calculations of Excess Consumption and the Excess Consumption Costs.

       Premises five (5) times per week (except for holidays) , comparable to
       that provided in other office buildings of similar size, quality and in

Landlord be required to provide any additional services if Tenant is in breach
of its obligation to pay any Rent hereunder as and when due and payable.

SECTION 5.3   TENANT'S OBLIGATION.  Tenant agrees to cooperate fully at all
times with Landlord and to abide by all regulations and requirements which

       as required under Section 5.101 through 5.104 above (each an "Essential
       Service") for any period (other than a reconstruction period conducted
       pursuant to Section 7.1 or Article 8 below) exceeding five (5)
       consecutive business days after written notice by Tenant to Landlord and

Landlord's approval shall not be deemed any kind of warranty or representation
by Landlord, including, without limitation, any warranty or representation as to

Building for the storage and maintenance of the provider's equipment, for the
fair market value of a provider's access to the Building, and the costs which
may reasonably be expected to be incurred by Landlord; (vii) the provider agrees
to deliver to Landlord detailed "as built" plans immediately after the

       than Tenant's Improvements under the Work Letter) to, or install any
       equipment or machinery (other than office equipment and unattached
       personal property) on, the Premises (all such changes, modifications,
       alterations, additions, improvements (other than Tenant's Improvements
       under the Work Letter) and installations approved by Landlord are herein
       collectively referred to as "Installations") if any such Installations

       tenants of the Building or (viii) violate any provision in Article 4
       above or Rider H-1 attached hereto. As to Installations not covered by
                ---------         
       the preceding sentence, Tenant will not perform same without the prior
       written consent of Landlord, which consent shall not be unreasonably
       withheld or delayed. All Installations shall be at Tenant's sole cost and
       expense. Without in any way limiting Landlord's consent rights, Landlord
       shall not be required to give its consent until (a) Landlord approves the
       contractor or person making such Installations and approves such
       contractor's insurance coverage to be provided in connection with the
       work, (b) Landlord approves final and complete plans and specifications
       for the work and (c) the appropriate governmental agency, if any, has

       to applicable governmental laws, rules and regulations, including,
       without limitation, the Disability Acts. Upon completion of the
       Installations, Tenant shall deliver to Landlord "as built" plans. If
       Landlord performs such Installations, Tenant shall pay Landlord, as
       additional Rent, the cost thereof plus five percent (5%) as reimbursement
       for Landlord's overhead. Each payment shall be made to Landlord within
       ten (10) days after receipt of an invoice from Landlord. All
       Installations that constitute improvements constructed within the
       Premises shall be surrendered with the Premises at the expiration or
       earlier termination of this Lease, unless Landlord requests that same be
       removed pursuant to Section 1.3 above. Tenant shall indemnify and hold
       Landlord harmless from and reimburse Landlord for and with respect to,
       any and all costs, expenses (including reasonable attorneys' fees),
       demands, claims, causes of action and liens, arising from or in
       connection with any Installations performed by or on behalf of Tenant
       (other than those performed by Landlord), EVEN IF THE SAME IS CAUSED BY
       THE NEGLIGENCE OR OTHER TORTIOUS CONDUCT OF LANDLORD OR LANDLORD IS
       STRICTLY LIABLE FOR SUCH COSTS, EXPENSES OR CLAIMS. All Installations
       performed by or on behalf of Tenant will be performed diligently and in a
       first-class workmanlike manner and in compliance with all applicable
       laws, ordinances, regulations and rules of any public authority having

       specifications which are prepared in connection with any construction of
       improvements (including without limitation, Tenant's Improvements) in the
       Premises shall not in any way be construed as or constitute a
       representation or warranty of Landlord as to the abilities of the
       contractor or the adequacy or sufficiency of such drawings, plans or
       specifications or the improvements to which they relate, for any use,
       purpose or condition.

6.305. Tenant's Generator. Subject to all of the terms and conditions of Section

       Austin and all other governmental authorities having jurisdiction over
       Tenant, the Property and the Generator, and (ii) the Generator conforms

       the Generator in good and operable condition and shall be responsible for
       the maintenance, repair and replacement of the Generator, as necessary.
       Further, Tenant shall indemnify and hold Landlord harmless from and
       against any and all claims, demands, fines, liabilities, costs, expenses,
       damages and causes of action accruing from or related to the Generator,
       EVEN IF THE SAME IS CAUSED BY THE NEGLIGENCE OF LANDLORD OR ANYONE ACTING
       FOR LANDLORD. In the event Tenant installs the Generator, Tenant shall
       reimburse Landlord within thirty (30) days after Tenant's receipt of an
       invoice, for the costs of landscaping and/or fencing installed by
       Landlord to screen the Generator from public view.

                         INSURANCE, FIRE AND CASUALTY

SECTION 7.1   TOTAL OR PARTIAL DESTRUCTION OF THE BUILDING OR THE PREMISES.  In
the event that the Building should be totally destroyed by fire or other
casualty or in the event the Building (or any portion thereof) should be so
damaged that rebuilding or repairs cannot be completed, in Landlord's reasonable
opinion, within one hundred eighty (180) days after commencement of repairs to
the Building, Landlord may, at its option, terminate this Lease, in which event
Basic Annual Rent and Additional Rent shall be abated during the unexpired
portion of this Lease effective with the date of such damage.  Landlord shall
provide Tenant of its determination of the rebuilding and restoration time
within forty-five (45) days after the date of the casualty.  Landlord shall
exercise the termination right pursuant to the preceding sentence, if at all, by
delivering written notice of termination to Tenant within ten (10) days after
determining that the repairs cannot be completed within such one hundred eighty
(180) day period.  In the event that the Premises should be so damaged by fire
or other casualty that rebuilding or repairs cannot be completed, in Landlord's
reasonable opinion,

within one hundred eighty (180) days after the commencement of repairs to the
Premises, Tenant may, at its option terminate this Lease, in which event Basic
Annual Rent and Additional Rent shall be abated during the unexpired portion of
this Lease, effective the date of termination. Tenant shall exercise the
termination right pursuant to the preceding sentence, if at all, by delivering
written notice of termination to Landlord within ten (10) days after being
advised by Landlord that the repairs cannot be completed within such one hundred
eighty (180) day period. In the event the Building or the Premises should be
damaged by fire or other casualty and, in Landlord's reasonable opinion, the
rebuilding or repairs can be completed within one hundred eighty (180) days
after the commencement of repairs to the Building or Premises, as applicable, or
if the damage should be more serious but neither Landlord nor Tenant elect to
terminate this Lease pursuant to this Section, in either such event Landlord
shall, within sixty (60) days after the date of such damage, commence (and
thereafter pursue with reasonable diligence) repairing the Building and the
Premises (including Tenant's Improvements), but only to the extent of insurance
proceeds actually received by Landlord for such repairs, to substantially the
same condition which existed immediately prior to the happening of the casualty.
In the event the insurance proceeds are not sufficient to restore the Building
and Premises to substantially the same condition which existed prior to the
casualty and Landlord does not elect to restore the Building and the Premises to
such condition, this Lease shall terminate upon notice by Landlord to Tenant of
Landlord's election not to restore the Building and Premises. In no event shall
Landlord be required to rebuild, repair or replace any part of the furniture,
equipment, fixtures, inventory, supplies or any other personalty or any other
improvements (except Tenant's Improvements to the extent set forth in the
preceding sentence), which may have been placed by Tenant within the Building or
at the Premises. Landlord shall allow Tenant a fair diminution of Basic Annual
Rent and Additional Rent during the time the Premises are unfit for occupancy;
provided, that if such casualty was caused by Tenant, its agents, employees,
licensees or invitees, Basic Annual Rent and Additional Rent shall be abated
only to the extent Landlord is compensated for such Basic Annual Rent and
Additional Rent by loss of rents insurance, if any. Notwithstanding Landlord's
restoration obligation, in the event any mortgagee under a deed of trust,
security agreement or mortgage on the Building should require that the insurance
proceeds be used to retire or reduce the mortgage debt or if the insurance
company issuing Landlord's fire and casualty insurance policy fails or refuses
to pay Landlord the proceeds under such policy, Landlord shall have no
obligation to rebuild and this Lease shall terminate upon notice by Landlord to
Tenant. Any insurance which may be carried by Landlord or Tenant against loss or
damage to the Building or to the Premises shall be for the sole benefit of the
party carrying such insurance and under its sole control.

      Party or (d) resulting from host liquor liability. If a third party files
      a lawsuit or brings any other legal action asserting a Claim against a
      Tenant Indemnified Party and that is covered by Landlord's indemnity, then
      Landlord, upon notice from the Tenant Indemnified Party, shall resist and
      defend such Claim through counsel reasonably satisfactory to the Tenant
      Indemnified Party. Landlord's obligations under this subsection shall
      survive the termination of this Lease.

                                 CONDEMNATION

SECTION 8.1   CONDEMNATION RESULTING IN CONTINUED USE NOT FEASIBLE.  If the
Property or any portion thereof that, in Landlord's reasonable opinion, is
necessary to the continued efficient and/or economically feasible use of the
Property shall be taken or condemned in whole or in part for public purposes, or
sold to a condemning authority in lieu of taking, then the term of this Lease
shall, at the option of Landlord, forthwith cease and terminate.

SECTION 8.2   TOTAL CONDEMNATION OF PREMISES.  In the event that all or
substantially all of the Premises is taken or condemned or sold in lieu thereof
or Tenant will be unable to use a substantial portion of the Premises for a
period of one hundred eighty (180) consecutive days by reason of a temporary
taking, either Landlord or Tenant may terminate this Lease by delivering written
notice thereof to the other within ten (10) business days after the taking,
condemnation or sale in lieu thereof.

SECTION 8.3   CONDEMNATION WITHOUT TERMINATION.  If upon a taking or
condemnation or sale in lieu of the taking of all or less than all of the
Property which gives either Landlord or Tenant the right to terminate this Lease
pursuant to Section 8.1 or 8.2 above and neither Landlord nor Tenant elect to
exercise such termination right, then this Lease shall continue in full force
and effect, provided that, if the taking, condemnation or sale includes any
portion of the Premises, the Basic Annual Rent and Additional Rent shall be
redetermined on the basis of the remaining square feet of Agreed Rentable Area
of the Premises.  Landlord, at Landlord's sole option and expense, shall restore
and reconstruct the Building to substantially its former condition to the extent
that the same may be reasonably feasible, but such work shall not be required to
exceed the scope of the work done by Landlord in originally constructing the
Building, nor shall Landlord in any event be required to spend for such work an
amount in excess of the amount received by Landlord as compensation or damages
(over and above amounts going to the mortgagee of the property taken) for the
part of the Building or the Premises so taken.

SECTION 8.4   CONDEMNATION PROCEEDS.  Landlord shall receive the entire award
(which shall include sales proceeds) payable as a result of a condemnation,
taking or sale in lieu thereof.  Tenant hereby expressly assigns to Landlord any
and all right, title and interest of Tenant now or hereafter arising in and to
any such award.  Tenant shall, however, have the right to recover from such
authority through a separate award which does not reduce Landlord's award, any
compensation as may be awarded to Tenant on account of moving and relocation
expenses and depreciation to and removal of Tenant's physical property.

                                   ARTICLE 9
                                     LIENS

Tenant shall keep the Premises and the Property free from all liens arising out
of any work performed, materials furnished or obligations incurred by or for
Tenant AND TENANT SHALL INDEMNIFY AND HOLD HARMLESS LANDLORD FROM AND AGAINST,
AND REIMBURSE LANDLORD FOR AND WITH RESPECT TO, ANY AND ALL CLAIMS, CAUSES OF
ACTION, DAMAGES, EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES), ARISING FROM
OR IN CONNECTION WITH ANY SUCH LIENS.  In the event that Tenant shall not,
within ten (10) days following notification to Tenant of the imposition of any
such lien, cause the same to be released of record by payment or the posting of
a bond in amount, form and substance acceptable to Landlord, Landlord shall
have, in addition to all other remedies provided herein and by law, the right
but not the obligation, to cause the same to be released by such means as it
shall deem proper, including payment of or defense against the claim giving rise
to such lien.  All amounts paid or incurred by Landlord in connection therewith
shall be paid by Tenant to Landlord on demand and shall bear interest from the
date of demand until paid at the rate set forth in Section 15.10 below.  Nothing
in this Lease shall be deemed or construed in any way as constituting the
consent or request of Landlord, express or implied, by inference or otherwise,
to any contractor, subcontractor, laborer or materialman for the performance of
any labor or the furnishing of any materials for any specific improvement,
alteration or repair of or to the Building or the Premises or any part thereof,
nor as giving Tenant any right, power or authority to contract for or permit the
rendering of any services or the furnishing of any materials that would give
rise to the filing of any mechanic's or other liens against the interest of
Landlord in the Property or the Premises.

                          TAXES ON TENANT'S PROPERTY

Tenant shall be liable for and shall pay, prior to their becoming delinquent,
any and all taxes and assessments levied against, and any increases in Real
Estate Taxes as a result of, any personal property or trade or other fixtures
placed by Tenant in or about the Premises and any improvements (other than
Tenant's Improvements) constructed in the Premises by or on behalf of Tenant.
In the event Landlord pays any such additional taxes or increases, Tenant will,
within ten (10) days after demand, reimburse Landlord for the amount thereof.

                           SUBLETTING AND ASSIGNING

SECTION 11.1  SUBLEASE AND ASSIGNMENT.  Tenant shall not assign this Lease, or
allow it to be assigned, in whole or in part, by operation of law or otherwise
or mortgage or pledge the same, or sublet the Premises or any part thereof or
permit the Premises to be occupied by any firm, person, partnership or
corporation or any combination thereof, other than Tenant, without the prior
written consent of Landlord, which shall not be unreasonably withheld so long as
Landlord does not elect to terminate this Lease under Section 11.2 below.  In no
event shall any assignment or sublease ever release Tenant from any obligation
or liability hereunder.  Without limiting Landlord's consent rights and as a
condition to obtaining Landlord's consent, (i) each assignee must assume all
obligations under this Lease and (ii) each sublessee must confirm that its
sublease is subject and subordinate to this Lease.  In addition, each assignee
and sublessee shall agree to cause the Premises to comply at all times with all
requirements of the Disability Acts (as amended), including, but not limited to,
obligations arising out of or associated with such assignee's or subtenant's use
of or activities or business operations conducted within the Premises.  No
assignee or sublessee of the Premises or any portion thereof may assign or
sublet the Premises or any portion thereof.  Consent by Landlord to one or more
assignments or sublettings shall not operate as a waiver of Landlord's rights as
to any subsequent assignments and/or sublettings.  Tenant shall deliver to
Landlord a copy of each assignment or sublease entered into by Tenant promptly
after the execution thereof, whether or not Landlord's consent is required in
connection therewith.  Any assignment made by Tenant shall be in recordable form
and shall contain a covenant of assumption by the assignee running to Landlord.
All reasonable legal fees and expenses incurred by Landlord in connection with
any assignment or sublease proposed by Tenant will be the responsibility of
Tenant and will be paid by Tenant within five (5) days of receipt of an invoice
from Landlord.  In addition, Tenant will pay to Landlord an administrative
overhead fee of $500.00 in consideration for Landlord's review of any requested
assignment or sublease.  Notwithstanding the foregoing, the following shall not
be an "assignment" of this Lease: (i) Tenant's stock becomes publicly traded,
(ii) the sale of all of the stock of Tenant to a third party, provided that
after taking such sale into effect, the third party has a net worth equal to or
greater than the net worth of Tenant on the date hereof,  (iii) the sale of
substantially all of the assets of Tenant to a third party provided that after
taking such sale into effect, such third party has a net worth equal to or
greater than Tenant as of the date hereof; (iv) a merger of Tenant into or with
a third party, provided that after taking such merger into effect, the surviving
entity has a net worth equal to or greater than the net worth of Tenant on the
date hereof.

SECTION 11.2  LANDLORD'S RIGHTS.

11.201  Landlord's Termination and Consent Rights.
        ----------------------------------------- 

        (a) If Tenant desires to sublease any portion of the Premises or assign
        this Lease, Tenant shall submit to Landlord (a) in writing the name of
        the proposed subtenant or assignee, the nature of the proposed
        subtenant's or assignee's business and, in the event of a sublease, the
        portion of the Premises which Tenant desires to sublease (if the
        proposed sublease space is less than all of the Premises, such portion
        is herein referred to as the "Proposed Sublease Space"), (b) a current
        balance sheet and income statement for such proposed subtenant or
        assignee, (c) a copy of the proposed form of sublease or assignment, and
        (d) such other information as Landlord may reasonably request
        (collectively, the "Required Information").

        (b) Landlord shall, within fifteen (15) days after Landlord's receipt of
        the Required Information deliver to Tenant a written notice (each such
        notice, a "Landlord Response") in which Landlord either (i) terminates
        this Lease, if Tenant desires to sublease all of the Premises or assign
        this Lease, (ii) terminates this Lease only as to the Proposed Sublease
        Space, if the Proposed Sublease Space is less than the entire Premises,
        (iii) consents to the proposed sublease or assignment, or (iv) withholds
        its consent to the proposed sublease or assignment, which consent shall
        not be unreasonably withheld so long as Landlord does not elect to
        terminate this Lease under subparts (i) or (ii) above and so long as
        Landlord has received all Required Information. Landlord shall be deemed
        to have reasonably withheld its consent to any sublease or assignment if
        the refusal is based on (i) Landlord's determination (in its sole
        discretion) that such subtenant or assignee is not of the character or
        quality of a tenant to whom Landlord would generally lease space of the
        Building, (ii) the fact that such sublease or assignment is not in form
        and of substance reasonably satisfactory to Landlord, (iii) such
        sublease or assignment conflicts in any manner with this Lease,
        including, but not limited to, the Permitted Use under Item 10 of the
        Basic Lease Provisions or Section 4.1 of the Supplemental Lease
        Provisions, (iv) the proposed subtenant or assignee is a governmental
        entity or a medical office, (v) the proposed subtenant's or assignee's
        primary business is prohibited by any non-compete clause then affecting
        the Building, (vi) the proposed subtenant or assignee is a tenant of the
        Building or Landlord is negotiating with the proposed subtenant or
        assignee to become a tenant of any building owned by Landlord in the
        project known as Barton Oaks Plaza (the "Project"), (vii) the population
        density of the proposed subtenant or assignee within the Premises will
        exceed the general population density requirement set forth in
        subsection 4.101 hereof, (viii) the character of the business to be
        conducted within the Premises by the proposed subtenant or assignee is
        likely to substantially increase the expenses or costs or providing
        Building services, or the burden on parking, existing janitorial
        services or elevators in the Building, (ix) the sublease or assignment
        would cause Landlord to breach any recorded covenants or contractual
        obligations to which the Property or Landlord is subject or (x) such
        sublessee or assignee has a net worth less than that of Tenant at the
        time Tenant submits the Required Information.

        (c) If Landlord does not timely exercise its termination right with
        respect to the proposed sublease or assignment within the required
        fifteen (15) days period, then Landlord shall be deemed to have waived
        its right to terminate this Lease with respect to the applicable
        assignment or sublease, but Landlord shall have the right to consent or
        withhold its consent to the applicable proposed assignment or sublease,
        by delivering written notice thereof to Tenant within such fifteen (15)
        day period. If Landlord 

                                     -14-
<PAGE>
 
        does not exercise its right to consent or withhold its consent in
        respect of a proposed assignment or sublease within the required fifteen
        (15) day period, then Landlord shall be deemed to have consented to the
        proposed assignment or sublease.

11.202  Effect of Termination.  If Landlord timely exercises its option to
        ---------------------                                             
        terminate this Lease as to the entire Premises as provided in subsection
        11.201, then this Lease shall terminate on a date specified by Landlord
        in the Landlord Response (the "Specified Termination Date"), which
        Specified Termination Date shall not be sooner than 30 days after the
        date of Landlord's Response, nor later than 90 days after the date of
        Landlord's Response, and the Basic Rent and Additional Rent shall be
        paid and apportioned to the Specified Termination Date. If Landlord
        timely exercises its option to terminate this Lease as to only the
        Proposed Sublease Space, then (i) this Lease shall end and expire with
        respect to the Proposed Sublease Space on the applicable Specified
        Termination Date, (ii) from and after the applicable Specified
        Termination Date, the Basic Rent shall be reduced by the amount of Basic
        Rent that was being paid in respect of the Proposed Sublease Space as of
        the applicable Specified Termination Date, (iii) Tenant's Pro Rata Share
        Percentage shall be recalculated based on the square feet of rentable
        area included in the Premises (exclusive of such Proposed Sublease
        Space), (iv) Tenant's estimated payments of Additional Rent shall be
        recalculated on the basis of the revised Tenant's Pro Rata Share
        Percentage, and (v) if the Proposed Sublease Space adjoins another
        portion of the Premises, Tenant shall, at Tenant's sole cost and
        expense, construct and finish such demising walls as are necessary to
        physically separate the Premises from the Proposed Sublease Space, and
        (vi) if the Proposed Sublease Space is part of a floor which is fully
        included in the Premises, then Landlord shall have the right, at
        Tenant's sole cost and expense, (a) to construct and finish in
        accordance with Building standards or to cause Tenant to construct and
        finish in accordance with Building standards such demising walls as are
        necessary (x) to construct a public corridor so as to convert the floor
        to a multi-tenant floor and (y) to convert the restrooms on such floor
        (including access thereto) to restrooms which will serve the entire
        floor, as opposed to only the Premises, and (b) to make such revisions,
        if any, are necessary, to properly light, heat, cool and ventilate the
        public corridor and public restrooms. The alterations performed by
        Tenant pursuant to this paragraph shall be deemed Installations and
        therefore subject to the provisions of subsection 6.303.

SECTION 11.3  LANDLORD'S RIGHTS RELATING TO ASSIGNEE OR SUBTENANT.  To the
extent the rentals or income derived from any sublease or assignment exceed the
rentals due hereunder after deduction of the actual out of pocket costs paid by
Tenant in connection with the applicable sublease or assignment, fifty percent
(50%) of such excess rentals (the "Excess Sublease Rentals") shall be the
property of and paid over to Landlord in consideration for Landlord's consent to
the applicable assignment or sublease.  In the event Tenant is in default
hereunder, Landlord may at its option collect directly from such assignee or
sublessee all rents becoming due to Tenant under such assignment or sublease
Tenant hereby authorizes and directs any such assignee or sublessee to make such
payments of rent direct to Landlord upon receipt of notice from Landlord and
Tenant agrees that any such payments made by an assignee or sublessee to
Landlord shall, to the extent of the payments so made, be a full and complete
release and discharge of rent owed to Tenant by such assignee or sublessee.  No
direct collection by Landlord from any such assignee or sublessee shall be
construed to constitute a novation or a release of Tenant or any guarantor of
Tenant from the further performance of its obligations hereunder.  Receipt by
Landlord of rent from any assignee, sublessee or occupant of the Premises or any
part thereof shall not be deemed a waiver of the above covenant in this Lease
against assignment and subletting or a release of Tenant under this Lease.  In
the event that, following an assignment or subletting, this Lease or Tenant's
right to possession of the Premises is terminated for any reason, including
without limitation in connection with default by or bankruptcy of Tenant (which,
for the purposes of this Section 11.2, shall include all persons or entities
claiming by or through Tenant), Landlord may, at its sole option, consider this
Lease to be thereafter a direct lease to the assignee or subtenant of Tenant
upon the terms and conditions contained in this Lease, in which event all
rentals payable under such lease after the termination of this Lease or Tenant's
right to possession of the Premises shall be deemed the property of Landlord.

SECTION 11.4  ASSIGNMENT AND BANKRUPTCY.

11.401  Assignments after Bankruptcy.  If, pursuant to applicable bankruptcy law
        ----------------------------                                            
        (as hereinafter defined in Section 13.104), Tenant (or its successor in
        interest hereunder) is permitted to assign this Lease in disregard of
        the restrictions contained in this Article 11 (or if this Lease shall be
        assumed by a trustee for such person), the trustee or assignee shall
        cure any default under this Lease and shall provide adequate assurance
        of future performance by the trustee or assignee, including (i) the
        source of payment of Basic Annual Rent and performance of other
        obligations under this Lease (for which adequate assurance shall mean
        the deposit of cash security with Landlord in an amount equal to the sum
        of one (1) year's Basic Annual Rent, Additional Rent and other Rent then
        reserved hereunder for the calendar year preceding the year in which
        such assignment is intended to become effective, which deposit shall be
        held by Landlord, without interest, for the balance of the Term as
        security for the full and faithful performance of all of the obligations
        under this Lease on the part of Tenant yet to be performed and that any
        such assignee of this Lease shall have a net worth exclusive of good
        will, computed in accordance with the generally accepted accounting
        principles, equal to at least ten (10) times the aggregate of the Basic
        Annual Rent reserved hereunder); and (ii) that the use of the Premises
        shall be in accordance with the requirements of Article 4 hereof and,
        further, shall in no way diminish the reputation of the Building as a
        first-class office building or impose any additional burden upon the
        Building or increase the services to be provided by Landlord. If all
        defaults are not cured and such adequate assurance is not provided
        within sixty (60) days after there has been an order for relief under
        applicable bankruptcy law, then this Lease shall be deemed rejected,
        Tenant or any other person in possession shall immediately vacate the
        Premises, and Landlord shall be entitled to retain any Basic Annual
        Rent, Additional Rent and any other Rent, together with any security
        deposit previously received from the Tenant, and shall have no further
        liability to Tenant or any person claiming through Tenant or any
        trustee.

11.402  Bankruptcy of Assignee.  If Tenant assigns this Lease to any party and
        ----------------------                                                
        such party or its successors or representatives causes termination or
        rejection of this Lease pursuant to applicable bankruptcy law, then,
        notwithstanding any such termination or rejection, Tenant (i) shall
        remain fully liable for the performance of all covenants, agreements,
        terms, provisions and conditions contained in this Lease, as though the
        assignment never occurred and (ii) shall, without in any way limiting
        the foregoing, in writing ratify the terms of this Lease, as same
        existed immediately prior to the termination or rejection.

SECTION 11.5  LIMITATION ON RECAPTURE RIGHTS.    Notwithstanding the foregoing,
Landlord shall not be entitled to cancel this Lease with respect to any sublease
which has a term of less than seventy-five percent (75%) of the remaining Term
of this Lease at the commencement of such sublease provided that the Agreed
Rentable Area of the Premises covered by such sublease together 

                                     -15-
<PAGE>
 
with the Agreed Rentable Area of the Premises covered by all other subleases as
of the commencement of such sublease does not exceed twenty-five percent (25%)
of the total rentable Agreed Rentable Area of the Premises.

                   TRANSFERS BY LANDLORD, SUBORDINATION AND
                         TENANT'S ESTOPPEL CERTIFICATE

SECTION 12.1  SALE OF THE PROPERTY.  In the event of any transfer of title to
the Building, the transferor shall automatically be relieved and freed of all
obligations of Landlord under this Lease accruing after such transfer so long as
such transferee assumes such obligations of Landlord in writing, provided that
if a Security Deposit has been made by Tenant, Landlord shall not be released
from liability with respect thereto unless Landlord transfers the Security
Deposit to the transferee.

SECTION 12.2  SUBORDINATION, ATTORNMENT AND NOTICE.  This Lease is subject and
subordinate to (i) any lease wherein Landlord is the tenant and to the liens of
any and all mortgages and deeds of trust, regardless of whether such lease,
mortgage or deed of trust now exists or may hereafter be created with regard to
all or any part of the Property, (ii) any and all advances (including interest
thereon) to be made under any such lease, mortgage or deed of trust and (iii)
all modifications, consolidations, renewals, replacements and extensions of any
such lease, mortgage or deed of trust; provided that the foregoing subordination
in respect of any mortgage or deed of trust placed on the Property after the
date hereof shall not become effective until and unless the holder of such
mortgage or deed of trust delivers to Tenant a non-disturbance agreement (which
may include Tenant's agreement to attorn as set forth below) permitting Tenant,
if Tenant is not then in default under, or in breach of any provision of, this
Lease, to remain in occupancy of the Premises in the event of a foreclosure of
any such mortgage or deed of trust.  Tenant also agrees that any lessor,
mortgagee or trustee may elect (which election shall be revocable) to have this
Lease superior to any lease or lien of its mortgage or deed of trust and, in the
event of such election and upon notification by such lessor, mortgagee or
trustee to Tenant to that effect, this Lease shall be deemed superior to the
said lease, mortgage or deed of trust, whether this Lease is dated prior to or
subsequent to the date of said lease, mortgage or deed of trust.  Tenant shall,
in the event of the sale or assignment of Landlord's interest in the Premises
(except in a sale-leaseback financing transaction), or in the event of the
termination of any lease in a sale-leaseback financing transaction wherein
Landlord is the lessee, attorn to and recognize such purchaser, assignee or
mortgagee as Landlord under this Lease.  Tenant shall, in the event of any
proceedings brought for the foreclosure of, or in the event of the exercise of
the power of sale under, any mortgage or deed of trust covering the Premises,
attorn to and recognize purchaser at such sale, assignee or mortgagee, as the
case may be, as Landlord under this Lease.  The above subordination and
attornment clauses shall be self-operative and no further instruments of
subordination or attornment need be required by any mortgagee, trustee, lessor,
purchaser or assignee.  In confirmation thereof, Tenant agrees that, upon the
request of Landlord, or any such lessor, mortgagee, trustee, purchaser or
assignee, Tenant shall execute and deliver whatever instruments may be required
for such purposes and to carry out the intent of this Section 12.2.

SECTION 12.3  TENANT'S ESTOPPEL CERTIFICATE.  Tenant shall, upon the request of
Landlord or any mortgagee of Landlord, without additional consideration, deliver
an estoppel certificate, consisting of reasonable statements required by
Landlord, any mortgagee or purchaser of any interest in the Property, which
statements may include but shall not be limited to the following: this Lease is
in full force and effect with rent paid through a specified date; this Lease has
not been modified or amended; Landlord is not in default and Landlord has fully
performed all of Landlord's obligations hereunder; and such other statements as
may reasonably be required by the requesting party.  If Tenant is unable to make
any of the statements contained in the estoppel certificate because the same is
untrue, Tenant shall with specificity state the reason why such statement is
untrue.  Tenant shall, if requested by Landlord or any such mortgagee, deliver
to Landlord a fully executed instrument in form reasonably satisfactory to
Landlord evidencing the agreement of Tenant to the mortgage or other
hypothecation by Landlord of the interest of Landlord hereunder.

                                    DEFAULT

SECTION 13.1  DEFAULTS BY TENANT.  The occurrence of any of the events described
in subsections 13.101 through 13.108 shall constitute a default by Tenant under
this Lease.

13.101  Failure to Pay Rent.  With respect to the first two payments of Rent not
        -------------------                                                     
        made by Tenant when due in any twelve (12) month period, the failure by
        Tenant to make either such payment to Landlord within three (3) business
        days after Tenant receives written notice specifying that the payment
        was not made when due. With respect to any other payment of Rent, the
        failure by Tenant to make such payment of Rent to Landlord when due, no
        notice of any such failure being required.

13.102  Failure to Perform.  Except for a failure covered by subsection 13.101
        ------------------                                                    
        above or 13.103 below, any failure by Tenant to observe and perform any
        provision of this Lease to be observed or performed by Tenant where such
        failure continues for thirty (30) days after written notice to Tenant,
        provided that if such failure cannot be cured within said thirty (30)
        day period, Tenant shall not be in default hereunder so long as Tenant
        commences curative action within such thirty (30) day period, diligently
        and continuously pursues the curative action and fully and completely
        cures the failure within sixty (60) days after such written notice to
        Tenant.

        (12) month period to perform and observe a particular provision of this
        Lease to be observed or performed by Tenant (other than the failure to

        filed against Tenant or Guarantor under applicable bankruptcy law
        (provided that no such levy, execution, legal process or petition filed

        Tenant or Guarantor shall vigorously contest the same by appropriate
        proceedings and shall remove or vacate the same within ninety (90) days
        from the date of its creation, service or filing).

        Rentable Area of the Premises by Tenant, which shall be conclusively
        presumed if Tenant is absent from the Premises for ten (10) consecutive
        days or more or if Tenant shall fail to move into or take possession of
        the Premises within ten (10) days after the date on which Rent is to
        commence under the terms of this Lease.

13.107  Loss of Right to do Business.  If Tenant is a corporation or limited
        ----------------------------

SECTION 13.2  REMEDIES OF LANDLORD.

13.201  Termination of the Lease.  Upon the occurrence of a default by Tenant
        ------------------------                                             
        hereunder, Landlord may, without judicial process, terminate this Lease
        by giving written notice thereof to Tenant (whereupon all obligations
        and liabilities of Landlord hereunder shall terminate) and, without
        further notice and without liability, repossess the Premises. Landlord
        shall be entitled to recover all loss and damage Landlord may suffer by
        reason of such termination, whether through inability to relet the
        Premises on satisfactory terms or otherwise, including without
        limitation, the following (without duplication of any element of
        damages):

        (a) accrued Rent to the date of termination and Late Charges, plus
        interest thereon at the rate established under Section 15.10 below from
        the date due through the date paid or date of any judgment or award by
        any court of competent jurisdiction, the unamortized cost of Tenant's
        Improvements, brokers' fees and commissions, attorneys' fees, moving
        allowances and any other costs incurred by Landlord in connection with
        making or executing this Lease, the cost of recovering the Premises and
        the costs of reletting the Premises (including, without limitation,
        advertising costs, brokerage fees, leasing commissions, reasonable
        attorneys' fees and refurbishing costs and other costs in readying the
        Premises for a new tenant);

        (b) the present value of the Rent (discounted at a rate of interest
        equal to eight percent [8%] per annum [the "Discount Rate"]) that would
        have accrued under this Lease for the balance of the Lease term but for
        such termination, reduced by the reasonable fair market rental value of
        the Premises for such balance of the Lease term (determined from the
        present value of the actual base rents, discounted at the Discount Rate,
        received and to be received from Landlord's reletting of the Premises
        or, if the Premises are not relet, the base rents, discounted at the
        Discount Rate, that with reasonable efforts could be collected by
        Landlord by reletting the Premises, calculated in accordance with
        subsection 13.206);

        (c) plus any other costs or amounts necessary to compensate Landlord for
        its damages.

13.202  Repossession and Re-Entry.  Upon the occurrence of a default by Tenant
        -------------------------                                             
        hereunder, Landlord may, without judicial process, immediately terminate
        Tenant's right of possession of the Premises (whereupon all obligations
        and liability of Landlord hereunder shall terminate), but not terminate
        this Lease, and, without notice, demand or liability, enter upon the
        Premises or any part thereof, take absolute possession of the same,
        expel or remove Tenant and any other person or entity who may be
        occupying the Premises and change the locks. If Landlord terminates
        Tenant's possession of the Premises under this subsection 13.202, (i)
        Landlord shall have no obligation whatsoever to tender to Tenant a key
        for new locks installed in the Premises, (ii) Tenant shall have no
        further right to possession of the Premises and (iii) Landlord will have
        the right to relet the Premises or any part thereof on such terms as
        Landlord deems advisable, taking into account the factors described in
        subsection 13.206. Any rent received by Landlord from reletting the
        Premises or a part thereof shall be applied first, to the payment of any
        indebtedness other than Rent due hereunder from Tenant to Landlord (in
        such order as Landlord shall designate), second, to the payment of any
        cost of such reletting, including, without limitation, refurbishing
        costs, reasonable attorneys' fees, advertising costs, brokerage fees and
        leasing commissions and third, to the payment of Rent due and unpaid
        hereunder (in such order as Landlord shall designate), and Tenant shall
        satisfy and pay to Landlord any deficiency upon demand therefor from
        time to time. Landlord shall not be responsible or liable for any
        failure to relet the Premises or any part thereof or for any failure to
        collect any rent due upon any such reletting. No such re-entry or taking
        of possession of the Premises by Landlord shall be construed as an
        election on Landlord's part to terminate this Lease unless a written
        notice of such termination is given to Tenant pursuant to subsection
        13.201 above. If Landlord relets the Premises, either before or after
        the termination of this Lease, all such rentals received from such lease
        shall be and remain the exclusive property of Landlord and Tenant shall
        not be, at any time, entitled to recover any such rental. Landlord may
        at any time after a reletting elect to terminate this Lease.

13.203  Cure of Default.  Upon the occurrence of a default hereunder by Tenant,
        ---------------                                                        
        Landlord may, without judicial process and without having any liability
        therefor, enter upon the Premises and do whatever Tenant is obligated to
        do under the terms of this Lease and Tenant agrees to reimburse Landlord
        on demand for any expenses which Landlord may incur in effecting
        compliance with Tenant's obligations under this Lease, and Tenant
        further agrees that Landlord shall not be liable for any damages
        resulting to Tenant from such action, WHETHER CAUSED BY THE NEGLIGENCE
        OF LANDLORD OR OTHERWISE.

                                     -17-
<PAGE>
 
13.204  Continuing Obligations.  No repossession of or re-entering upon the
        ----------------------                                             
        Premises or any part thereof pursuant to subsection 13.202 or 13.203
        above or otherwise and no reletting of the Premises or any part thereof
        pursuant to subsection 13.202 above shall relieve Tenant or any
        Guarantor of its liabilities and obligations hereunder, all of which
        shall survive such repossession or re-entering. In the event of any such
        repossession of or re-entering upon the Premises or any part thereof by
        reason of the occurrence of a default, Tenant will continue to pay to
        Landlord Rent required to be paid by Tenant.

13.205  Cumulative Remedies.  No right or remedy herein conferred upon or
        -------------------                                              
        reserved to Landlord is intended to be exclusive of any other right or
        remedy set forth herein or otherwise available to Landlord at law or in
        equity and each and every right and remedy shall be cumulative and in
        addition to any other right or remedy given hereunder or now or
        hereafter existing at law or in equity or by statute. In addition to the
        other remedies provided in this Lease and without limiting the preceding
        sentence, Landlord shall be entitled, to the extent permitted by
        applicable law, to injunctive relief in case of the violation, or
        attempted or threatened violation, of any of the covenants, agreements,
        conditions or provisions of this Lease, or to a decree compelling
        performance of any of the covenants, agreements, conditions or
        provisions of this Lease, or to any other remedy allowed to Landlord at
        law or in equity.

13.206  Mitigation of Damages.  For purposes of determining any recovery of rent
        ---------------------                                                   
        or damages by Landlord that depends upon what Landlord could collect by
        using reasonable efforts to relet the Premises, whether the
        determination is required under subsections 13.201 or 13.202 or
        otherwise, it is understood and agreed that:

        (a) Landlord may reasonably elect to lease other comparable, available
        space in the Building, if any, before reletting the Premises.

        (b) Landlord may reasonably decline to incur out-of-pocket costs to
        relet the Premises, other than customary leasing commissions and legal
        fees for the negotiation of a lease with a new tenant.

        (c) Landlord may reasonably decline to relet the Premises at rental
        rates below then prevailing market rental rates, because of the negative
        impact lower rental rates would have on the value of the Building and
        because of the uncertainty of actually receiving from Tenant the greater
        damages that Landlord would suffer from and after reletting at the lower
        rates.

        (d) Before reletting the Premises to a prospective tenant, Landlord may
        reasonably require the prospective tenant to demonstrate the same
        financial wherewithal that Landlord would require as a condition to
        leasing other space in the Building to the prospective tenant.

        (e) Identifying a prospective tenant to relet the Premises, negotiating
        a new lease with such tenant and making the Premises ready for such
        tenant will take time, depending upon market conditions when the
        Premises first become available for reletting, and during such time
        Landlord cannot reasonably be expected to collect any revenue from
        reletting.

        (f) Listing the Premises with a broker in a manner consistent with parts
        (a) through (e) above constitutes reasonable efforts on the part of
        Landlord to relet the Premises.

SECTION 13.3  DEFAULTS BY LANDLORD.  Landlord shall be in default under this
Lease if Landlord fails to perform any of its obligations hereunder and said
failure continues for a period of thirty (30) days after Tenant delivers written
notice thereof to Landlord (to each of the addresses required by this Section)
and each mortgagee who has a lien against any portion of the Property and whose
name and address has been provided to Tenant, provided that if such failure
cannot reasonably be cured within said thirty (30) day period, Landlord shall
not be in default hereunder if the curative action is commenced within said
thirty (30) day period and is thereafter diligently pursued until cured.  In no
event shall (i) Tenant claim a constructive or actual eviction or that the
Premises have become unsuitable hereunder or (ii) a constructive or actual
eviction or breach of the implied warranty of suitability be deemed to have
occurred under this Lease, prior to the expiration of the notice and cure
periods provided under this Section 13.3.  Any notice of a failure to perform by
Landlord shall be sent to Landlord at the addresses and to the attention of the
parties set forth in the Basic Lease Provisions.  Any notice of a failure to
perform by Landlord not sent to Landlord at all addresses and/or to the
attention of all parties required under this Section and to each mortgagee who
is entitled to notice or not sent in compliance with Article 14 below shall be
of no force or effect.

SECTION 13.4  LANDLORD'S LIABILITY.

13.401  Tenant's Rights in Respect of Landlord Default.  Tenant is granted no
        ----------------------------------------------                       
        contractual right of termination by this Lease, except to the extent and
        only to the extent set forth in Sections 7.1 and 8.2 above and Rider H-1
                                                                       ---------
        attached hereto. If Tenant shall recover a money judgment against
        Landlord, such judgment shall be satisfied only out of the right, title
        and interest of Landlord in the Property as the same may then be
        encumbered and Landlord shall not be liable for any deficiency. If
        Landlord is found to be in default hereunder by reason of its failure to
        give a consent that it is required to give hereunder, Tenant's sole
        remedy will be an action for specific performance or injunction. The
        foregoing sentence shall in no event be construed as mandatorily
        requiring Landlord to give consents under this Lease. In no event shall
        Landlord be liable to Tenant for consequential or special damages by
        reason of a failure to perform (or a default) by Landlord hereunder or
        otherwise. In no event shall Tenant have the right to levy execution
        against any property of Landlord other than its interest in the Property
        as hereinbefore expressly provided.

13.402  Certain Limitations on Landlord's Liability.  UNLESS COVERED BY
        -------------------------------------------                    
        SUBSECTION 7.502 ABOVE OR CAUSED BY LANDLORD'S GROSS NEGLIGENCE OR
        WILLFUL MISCONDUCT AND WITHOUT LIMITING THE PROVISIONS OF SECTION 7.4,
        LANDLORD SHALL NOT BE LIABLE TO TENANT FOR ANY CLAIMS, ACTIONS, DEMANDS,
        COSTS, EXPENSES, DAMAGE OR LIABILITY OF ANY KIND (i) arising out of the
        use, occupancy or enjoyment of the Premises by Tenant or any person
        therein or holding under Tenant or by or through the acts or omissions
        of any of their respective employees, officers, agents, invitees or
        contractors, (ii) caused by or arising out of fire, explosion, falling
        sheetrock, gas, electricity, water, rain, snow or dampness, or leaks in
        any part of the Premises, (iii) caused by or arising out of damage to
        the roof, pipes, appliances or plumbing works or any damage to or
        malfunction of heating, ventilation or air conditioning equipment, (iv)
        caused by tenants or any persons either in the Premises or elsewhere in
        the Building (other 

                                     -18-
<PAGE>
 
        than Common Areas) or by occupants of property adjacent to the Building
        or Common Areas or by the public or by the construction of any private,
        public or quasi-public work or (v) caused by any act, neglect or
        negligence of Tenant. In no event shall Landlord be liable to Tenant for
        any loss of or damage to property of Tenant or of others located in the
        Premises, the Building or any other part of the Property by reason of
        theft or burglary.

secured party under the Texas Business and Commerce Code and this lien and
security interest may be foreclosed by process of law.  The requirement of
reasonable notice prior to any sale under Article 9 of the Texas Business and
Commerce Code shall be met if such notice is given in the manner prescribed

conducted in a commercially reasonable manner if held in the Premises after the
time, place and method of sale and a general description of the types of
property to be sold have been advertised for ten (10) consecutive days prior to
the date of sale in a daily newspaper published in the county in Texas where the
Building is located.

                           MISCELLANEOUS PROVISIONS

SECTION 15.1  BUILDING NAME AND ADDRESS.  Tenant shall not, without the written
consent of Landlord, use the name of the Building for any purpose other than as
the address of the business to be conducted by Tenant in the Premises and in no
event shall Tenant acquire any rights in or to such names.  Landlord shall have
the right at any time to change the name, number or designation by which the
Building is known.

SECTION 15.2  SIGNAGE. Tenant shall not inscribe, paint, affix or display any
signs, advertisements or notices on or in the Building, except for such tenant
identification information as Landlord permits to be included or shown on the
directory in the main lobby and adjacent to the access door or doors to the
Premises. Unless prohibited by applicable sign ordinances, Landlord shall erect
at Landlord's expense, a multi-tenant monument sign (the "Multi-Tenant Monument
Sign") on the Property. Landlord agrees that Tenant shall have the right to
install a monument sign panel bearing Tenant's name on the top location of the
Multi-Tenant Monument Sign, subject to Landlord's reasonable approval of the
size, design, form and content of such panel. Tenant shall maintain the sign
panel bearing Tenant's name, and shall remove such panel from the Multi-Tenant
Monument Sign upon the expiration or earlier termination of this Lease. Subject
to compliance with the applicable condominium declaration requirements regarding
signage, including without limitation, obtaining the consent of all necessary
parties required under such declaration, Tenant shall have the right, at
Tenant's expense, to install one corporate sign on the exterior of the Building
on uppermost spandrel (the "Building Sign"); provided that (i) the Building Sign
shall not cover any window area, (ii) Tenant obtains all necessary approvals
from the City of Austin and all other governmental authorities (including any
applicable airport) having jurisdiction over Tenant, the Property, or the
Building Sign, (iii) the Building Sign conforms to all applicable laws, rules
and regulations of any governmental authorities having jurisdiction over the
Building Sign or the Property (including the condominium declaration applicable

evidencing that Tenant's contractors, agents, workmen, engineers or other
persons installing the Building Sign have in effect valid workmen's
compensation, public liability and builder's risk insurance in amounts and with
such companies and in such forms as Landlord may consider necessary or
appropriate for its protection. The location, design and size of the Building
Sign is subject to the approval of Landlord in its sole discretion. Tenant shall
pay all costs associated with the Building Sign, including without limitation,
installation expenses, maintenance and repair costs, utilities and insurance.
Tenant shall indemnify and hold Landlord harmless from and against any and all
claims, demands, fines,

liabilities, costs, expenses, damages, actions and causes of action accruing
from or related to the Building Sign, EVEN IF CAUSED BY THE NEGLIGENCE OF
LANDLORD OR IF LANDLORD IS STRICTLY LIABLE THEREFOR. Tenant agrees that Landlord
shall have the right to temporarily remove and replace the Building Sign in
connection with and during the course of any repairs, changes, alterations,
modifications, renovations or additions to the Building. Tenant shall maintain
the Building Sign in good condition. If Tenant is in default under the Lease (as
provided in Section 13.1 of the Lease) or if Tenant vacates ninety percent (90%)
or more of the Agreed Rentable Area of the Premises (which shall be presumed if
Tenant is absent from the Premises for ten (10) consecutive days or more or if
Tenant fails to move into or take possession of the Premises within ten (10)
days after the date on which Rent is to commence under the terms of the Lease),
Tenant's rights with respect to the Building Sign under this section shall
terminate and Landlord shall have the option to remove such signage at Tenant's
sole cost and expense. Upon expiration or earlier termination of the Lease,
Tenant shall, at its sole cost and expense, remove the Building Sign and repair
all damage caused by such removal.

SECTION 15.3  NO WAIVER.  No waiver by Landlord or by Tenant of any provision of
this Lease shall be deemed to be a waiver by either party of any other provision
of this Lease.  No waiver by Landlord of any breach by Tenant shall be deemed a
waiver of any subsequent breach by Tenant of the same or any other provision.
No waiver by Tenant of any breach by Landlord shall be deemed a waiver of any
subsequent breach by Landlord of the same or any other provision.  The failure
of Landlord or Tenant to insist at any time upon the strict performance of any
covenant or agreement or to exercise any option, right, power or remedy
contained in this Lease shall not be construed as a waiver or a relinquishment
thereof for the future.  Landlord's consent to or approval of any act by Tenant
requiring Landlord's consent or approval shall not be deemed to render
unnecessary the obtaining of Landlord's consent to or approval of any subsequent
act of Tenant.  Tenant's consent to or approval of any act by Landlord requiring
Tenant's consent or approval shall not be deemed to render unnecessary the
obtaining of Tenant's consent to or approval of any subsequent act of Landlord.
No act or thing done by Landlord or Landlord's agents during the term of this
Lease shall be deemed an acceptance of a surrender of the Premises, unless done
in writing signed by Landlord.  The delivery of the keys to any employee or
agent of Landlord shall not operate as a termination of this Lease or a
surrender of the Premises.  The acceptance of any Rent by Landlord following a
breach of this Lease by Tenant shall not constitute a waiver by Landlord of such
breach or any other breach.  The payment of Rent by Tenant following a breach of
this Lease by Landlord shall not constitute a waiver by Tenant of any such
breach or any other breach.  No waiver by Landlord or Tenant of any provision of
this Lease shall be deemed to have been made unless such waiver is expressly
stated in writing signed by the waiving party.  No payment by Tenant or receipt
by Landlord of a lesser amount than the monthly installment of Rent due under
this Lease shall be deemed to be other than on account of the earliest Rent due
hereunder, 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 which may
be available to Landlord.

SECTION 15.4  APPLICABLE LAW.  This Lease shall be governed by and construed in
accordance with the laws of the State of Texas.

is hereby granted a nonexclusive right to use the Common Areas and Service
Corridors during the term of this Lease for their intended purposes, in common
with others designated by Landlord, subject to the terms and conditions of this
Lease, including, without limitation, the Rules and Regulations.  The Building,
Common Areas, Service Corridors and Service Areas will be at all times under the
exclusive control, management and operation of the Landlord.  Tenant agrees and
acknowledges that the Premises (whether consisting of less than one floor or
consisting of one or more full floors within the Building) do not include, and
Landlord hereby expressly reserves for its sole and exclusive use, any and all
mechanical, electrical, telephone and similar rooms, janitor closets, elevator,
pipe and other vertical shafts and ducts, flues, stairwells, any area above the
acoustical ceiling and any other areas not specifically shown on Exhibit A as

Landlord has agreed to pay the fees of the broker (but only the broker) named in
Item 9 of the Basic Lease Provisions to the extent that Landlord has agreed to
do so pursuant to a written agreement with such broker.

SECTION 15.8  SEVERABILITY.  If any provision of this Lease or the application
thereof to any person or circumstances shall be invalid or unenforceable to any
extent, the application of such provisions to other persons or circumstances and
the remainder of this Lease shall not be affected thereby and shall be enforced
to the greatest extent permitted by law.

SECTION 15.9  EXAMINATION OF LEASE. Submission by Landlord of this instrument to
Tenant for examination or signature does not constitute a reservation of or
option for lease. This Lease will be effective as a lease or otherwise only upon
execution by and delivery to both Landlord and Tenant.

                   PLANS TO BE AGREED UPON/FINISH ALLOWANCE

     This Exhibit is attached to and a part of that certain Lease Agreement
dated as of August 4, 1998, executed by and between B. O. III, LTD., a Texas
limited partnership, and VIGNETTE, INC., a Delaware corporation. Any capitalized
term used but not defined herein shall have the meaning assigned to it in the
provisions designated in the Lease as the Supplemental Lease Provisions.
Landlord and Tenant mutually agree as follows:

1.   PLANS.
     ----- 

1.1  Space Plan. On or before August 15, 1998, a space planner engaged by Tenant
     ----------
and approved by Landlord shall, at Tenant's expense, prepare and deliver to
Landlord a space plan for the Premises showing, regardless of the quantities of
such items, the location of all partitions and doors and the lay-out of the
Premises. Landlord will at all times cooperate with Tenant's space planner (who
shall be subject to the reasonable approval of Landlord) to efficiently and
expeditiously arrive at an acceptable lay-out of the Premises. Landlord will
approve or disapprove in writing the space plan within three (3) business days
after receipt from Tenant and if disapproved, Landlord shall provide Tenant's
space planner with specific reasons for disapproval. If Landlord fails to
approve or disapprove the space plan on or before the end of such three (3)
business day period, Landlord shall be deemed to have approved the last
submitted space plan. The foregoing process shall be repeated until Landlord has
approved (which shall include deemed approval) the space plan (such space plan,
when approved by Landlord and Tenant, is herein referred to as the "Space
Plan").

1.2  Compliance With Disability Acts. Tenant has provided Tenant's space planner
     -------------------------------     
with all information needed to cause the construction of Tenant's Improvements
to be completed such that Tenant, the Premises and Tenant's Improvements (as
constructed) will be in compliance with the Disability Acts. TENANT SHALL BE
RESPONSIBLE FOR AND SHALL INDEMNIFY AND HOLD HARMLESS LANDLORD FROM AND AGAINST
ANY AND ALL CLAIMS, LIABILITIES AND EXPENSES (INCLUDING, WITHOUT LIMITATION
REASONABLE ATTORNEYS' FEES AND EXPENSES) INCURRED BY OR ASSERTED AGAINST
LANDLORD BY REASON OF OR IN CONNECTION WITH ANY VIOLATION OF THE DISABILITY ACTS
ARISING FROM OR OUT OF (i) Tenant's employer-employee obligations, or (ii)
violations by Tenant and/or Tenant's Improvements or the Premises not being in
compliance with the Disability Acts. The foregoing indemnity shall not include
any claims, liabilities or expenses (including reasonable attorneys' fees and
expenses) arising out of the negligence or gross negligence of Landlord or
Landlord's employees, agents or contractors.

1.3  Construction Plans.  On or before fifteen (15) days after approval of the
     ------------------                                                       
Space Plan by Landlord and Tenant, a licensed architect reasonably acceptable to
Landlord (which architect may be the approved space planner if the space planner
is a licensed architect), at Tenant's expense, will prepare construction plans
and specifications (such construction plans and specifications, when approved by
Landlord and Tenant, and all changes and amendments thereto agreed to by
Landlord and Tenant in writing, are herein called the "Construction Plans") for
all of Tenant's improvements requested pursuant to the Space Plan (all
improvements required by the Construction Plans are herein called "Tenant's
Improvements"), including color and design schemes, detail and finish drawings
for partitions, doors, reflected ceiling, telephone outlets, electrical switches
and outlets and Building standard heating, ventilation and air conditioning
equipment and controls. Within five (5) business days after construction plans
and specifications are delivered to Landlord, Landlord shall approve or
disapprove same in writing and if disapproved, Landlord shall provide Tenant's
architect specific reasons for disapproval. The foregoing process shall continue
until the construction plans and specifications are approved by Landlord;
provided that if Landlord fails to respond in any five (5) business day period,
Landlord shall be deemed to have approved the last submitted construction plans.
Landlord hereby agrees that Landlord shall not be entitled to disapprove
construction plans except for the following reasons: (i) the construction plans
do not conform to applicable laws, rules and regulations, (ii) the construction
plans or specifications will not accommodate Building standard heating, cooling,
mechanical, electrical or plumbing improvements, (iii) the construction plans or
specifications do not conform to the Space Plan, (iv) the construction required
by the construction plans could in Landlord's judgment affect the structural
integrity or any structural member of the Building or any part thereof or
requires a floor of the Building to be cut through or in Landlord's judgment
will adversely affect existing Building standard heating, cooling, mechanical,
electrical or plumbing improvements in any part of the Building, (v) the design
and/or color of the improvements which can been seen from the Common Areas do
not conform to the design and/or color scheme generally found in other parts of
the Building, (vi) the work required by the construction plans affects the
exterior of the Premises or the Building, or (vii) the construction plans are
incomplete or contain material errors or omissions (collectively, "Permitted
Objections"). If the construction plans and specifications are not approved in
writing by both Tenant and Landlord on or before September 15, 1998 on account
of Permitted Objections, Landlord may, at its sole option, terminate the Lease
and this Agreement, whereupon shall have no further liability or obligation
thereunder or hereunder. If Landlord does not elect to so terminate, then each
day after September 15, 1998, that the construction plans are not approved by
Tenant shall constitute one (1) day of Tenant Delay. Tenant shall reimburse
Landlord for the cost of Landlord's architectural review of the Space Plan and
the Construction Plans within thirty (30) days of receipt of an invoice
therefor.

1.4  Changes to Approved Plans.  If any re-drawing or re-drafting of either the
     -------------------------                                                 
approved Space Plan or the approved Construction Plans is necessitated by
changes (all of which shall be subject to Landlord's written approval) requested
by Tenant after approval by Landlord and Tenant, the expense of any such re-
drawing, re-drafting or re-reviewing by Landlord's architect required in
connection therewith and the expense of any work and improvements necessitated
by such re-drawing or re-drafting will be charged to Tenant.

1.5  Coordination of Planners and Designers.  If Tenant shall arrange for
     --------------------------------------                              
interior design services, whether with Landlord's space planner or any other
planner or designer, it shall be Tenant's responsibility to cause necessary
coordination of its agents' efforts with Landlord's agents to ensure that no
delays are caused to either the planning or construction of the Tenant's
Improvements.

1.6. Building Standard Materials. Tenant shall use Building standard materials
     ---------------------------                                              
in connection the design and construction of the Tenant's Improvements,
including without limitation, Building standard doors, frames, hardware,
lighting, ceiling tile and occupancy sensors.

2.   CONSTRUCTION AND COSTS OF TENANT'S IMPROVEMENTS.
     ----------------------------------------------- 
 
2.1  Selection of Contractor.
     ----------------------- 

     (a)  Landlord agrees to bid the construction of Tenant's Improvements to at
          least three (3) mutually acceptable general contractors (unless a
          lesser number is approved by Tenant) within two (2) business days
          after Landlord's approval of the Construction Plans. Landlord shall
          request that all contractors submit their respective bids within two
          (2) weeks after receipt of the bid package. Landlord shall also submit
          the Construction Plans for permit within two (2) business days after
          Landlord's approval of the Construction Plans.

     (b)  Landlord and Tenant shall jointly review any bids, and make
          adjustments in the bids, if necessary, for inconsistent assumptions in
          order to reflect an equitable comparison. Tenant shall select a
          contractor within two (2) business days after Landlord's receipt of
          all bids. Within three (3) business days after Tenant's selection of
          the Contractor, Landlord shall enter into a construction contract with
          the Contractor consistent with the terms of the bid to construct the
          Tenant's Improvements (the "Construction Contract"). Notwithstanding
          anything to the contrary contained herein, if Tenant has not selected
          a contractor and Landlord has not executed a Construction Contract
          with such Contractor by October 15, 1998, then each day after October
          15, 1998 shall constitute a day of Tenant Delay (hereinafter defined).

2.2  Construction Obligation and Finish Allowance.
     -------------------------------------------- 

     (a)  Landlord agrees to construct Tenant's Improvements, at Tenant's cost
          and expense; provided, however, Landlord shall provide Tenant with an
          allowance up to $17.75 per square foot of Agreed Rentable Area in the
          initial Premises (the "Finish Allowance"), which allowance shall be
          disbursed by Landlord, from time to time, for payment of (in the
          following priority) (i) the contract sum required to be paid to the
          general contractor engaged to construct Tenant's Improvements, which
          contract sum shall include without limitation, the costs of any and
          all payment and performance bonds required by Landlord in connection
          with the construction of Tenant's Improvements and any other costs
          incurred by such general contractor to comply with the construction
          requirements applicable to the Building (the "Contract Sum"), (ii) the
          fees of the preparer of the Space Plan and the Construction Plans,
          (iii) payment of the Construction Management Fee (hereinafter
          defined), and (iv) such other costs related to the leasehold
          improvements (such as equipment, appliances and furnishings) as
          Landlord specifically approves in writing, it being understood that
          Landlord shall have no obligation whatsoever to fund any portion of
          the Finish Allowance for such other costs. Upon completion of Tenant's
          Improvements and in consideration of Landlord administering the
          construction of Tenant's Improvements, Tenant agrees to pay Landlord a
          fee equal to five percent (5%) of the Contract Sum to construct
          Tenant's Improvements (the "Construction Management Fee") (the
          foregoing costs are collectively referred to as the "Permitted
          Costs").

     (b)  Title to any equipment, appliances, furnishings or personalty
          installed in the Premises and purchased with any portion of the Finish
          Allowance shall pass to Landlord upon payment of the invoice cost
          thereof and Tenant shall not remove any such equipment, appliances,
          furnishings or personalty from the Premises without Landlord's
          express, prior written consent or unless requested by Landlord in
          connection with the expiration or earlier termination of the Lease.

2.3  Excess Costs.  If the sum of the Permitted Costs exceeds the Finish
     ------------                                                       
Allowance, then Tenant shall pay all such excess costs ("Excess Costs"). Tenant
agrees to keep the Premises free from any liens arising out of nonpayment of
Excess Costs. In the event that any such lien is filed and Tenant, within ten
(10) days following such filing fails to cause same to be released of record by
payment or posting of a proper bond, Landlord shall have, in addition to all
other remedies provided herein and by law, the right, but not the obligation, to
cause the same to be released by such means as it in its sole discretion deems
proper, including payment of or defense against the claim giving rise to such
lien. All sums paid by Landlord in connection therewith shall constitute Rent
under the Lease and a demand obligation of Tenant to Landlord and such
obligation shall bear interest at the rate provided for in Section 15.10 of the
Supplemental Lease Provisions from the date of payment by Landlord until the
date paid by Tenant.

2.4  Construction Deposit.  Tenant shall remit to Landlord an amount (the
     --------------------                                                
"Prepayment") equal to the projected Excess Costs, if any, within five (5)
working days after commencement of construction by Landlord. On or prior to the
Commencement Date, Tenant shall deliver to Landlord the actual Excess Costs,
minus the Prepayment previously paid. Failure by Tenant to timely tender to
Landlord the full Prepayment shall permit Landlord to stop all work until the
Prepayment is received. All sums due Landlord under this Section 2.4 shall be
considered Rent under the terms of the Lease and nonpayment shall constitute a
default under the Lease and entitle Landlord to any and all remedies specified
in the Lease.

3.   DELAYS.  Delays in the completion of construction of Tenant's Improvements
     ------                                                                    
or in obtaining a certificate of occupancy, if required by the applicable
governmental authority, caused by Tenant, Tenant's Contractors (hereinafter
defined) or any person, firm or corporation employed by Tenant or Tenant's
Contractors shall constitute "Tenant Delays". Landlord agrees to Substantially
Complete construction of the Tenant's Improvements on or before 75 days after
Landlord executes the Construction Contract; provided however, if a building
permit for the construction of Tenant's Improvements has not been issued within
twenty (20) days after Landlord's execution of the Construction Contract, then
the foregoing 75 day period shall be extended by one day for each day after such
twenty (20) day period that a building permit for the construction of Tenant's
Improvements has not been issued. Further, such 75 day period shall also be
extended by one day for each day of Tenant Delays occurring after Landlord's
execution of the Construction Contract. In the event Landlord fails to
Substantially Complete the construction of the Tenant's Improvements by the
within the time period set forth above (as adjusted for Tenant Delays and
failure to obtain a building permit pursuant to the foregoing), Landlord shall
pay to Tenant, as liquidated damages, the sum of $40,000.00 per month for each
month or portion thereof occurring after such 75 day period (as adjusted for
Tenant Delays and failure to obtain a building permit) until the date of
Substantial Completion of the Tenant's Improvements, provided that such monthly
amount shall be prorated on a daily basis for the first fifteen (15) days after
the 75 day period (as adjusted for Tenant Delays and failure to obtain a
building permit) that Landlord fails to Substantially Complete the Tenant's
Improvements. Landlord and Tenant agree that Tenant's damages resulting from
Landlord's failure to Substantially Complete the Tenant's Improvements within
the period set forth above would be difficult to determine and that the
liquidated damages amount is a reasonable estimate of such damages and is not a
penalty. In the event that Tenant's Improvements are not Substantially Complete
by the Commencement Date referenced in Item 6 of the Basic Lease Provisions,
then the Commencement Date referenced in Item 6 shall be amended to be the
Adjusted Substantial Completion Date 

                                      D-2
<PAGE>
 
(hereinafter defined) and the Expiration Date referenced in Item 7 of the Basic
Lease Provisions shall be adjusted forward by the same number of days as is the
Commencement Date, so that the term of the Lease will be the term set forth in
Item 5 of the Basic Lease Provisions. The Adjusted Substantial Completion Date
shall be the date Tenant's Improvements are Substantially Complete, adjusted
backward, however, by one day for each day of Tenant Delays, if any. The
foregoing adjustments in the Commencement Date and the Expiration Date and
payment of the foregoing described liquidated damages shall be Tenant's sole and
exclusive remedy in the event Tenant's Improvements are not Substantially
Complete by the initial Commencement Date set forth in Item 6 of the Basic Lease
Provisions.

4.   SUBSTANTIAL COMPLETION AND PUNCH LIST.  The terms "Substantial Completion"
     -------------------------------------                                     
and "Substantially Complete," as applicable, shall mean when Tenant's
Improvements are sufficiently completed in accordance with the Construction
Plans so that Tenant can reasonably use the Premises for the Permitted Use (as
described in Item 10 of the Basic Lease Provisions). When Landlord considers
Tenant's Improvements to be Substantially Complete, Landlord will notify Tenant
and within two (2) business days thereafter, Landlord's representative and
Tenant's representative shall conduct a walk-through of the Premises and
identify any necessary touch-up work, repairs and minor completion items as are
necessary for final completion of Tenant's Improvements. Neither Landlord's
representative nor Tenant's representative shall unreasonably withhold his
agreement on punch list items. Landlord will use reasonable efforts to cause the
contractor to complete all punch list items within thirty (30) days after
agreement thereon.

5.   TENANT'S CONTRACTORS.  If Tenant should desire to enter the Premises or
     --------------------                                                   
authorize its agent to do so prior to the Commencement Date of the Lease, to
perform approved work not requested of the Landlord, Landlord shall permit such
entry if:

     (a)  Tenant shall use only such contractors which Landlord shall approve in
          its reasonable discretion and Landlord shall have approved the plans
          to be utilized by Tenant, which approval will not be unreasonably
          withheld; and

     (b)  Tenant, its contractors, workmen, mechanics, engineers, space planners
          or such others as may enter the Premises (collectively, "Tenant's
          Contractors"), work in harmony with and do not in any way disturb or
          interfere with Landlord's space planners, architects, engineers,
          contractors, workmen, mechanics or other agents or independent
          contractors in the performance of their work (collectively,
          "Landlord's Contractors"), it being understood and agreed that if
          entry of Tenant or Tenant's Contractors would cause, has caused or is
          causing a material disturbance to Landlord or Landlord's Contractors,
          then Landlord may, with notice, refuse admittance to Tenant or
          Tenant's Contractors causing such disturbance; and

     (c)  Tenant (notwithstanding the first sentence of subsection 7.201 of the
          Supplemental Lease Provisions), Tenant's Contractors and other agents
          shall provide Landlord sufficient evidence that each is covered under
          such Worker's Compensation, public liability and property damage
          insurance as Landlord may reasonably request for its protection.

Landlord shall not be liable for any injury, loss or damage to any of Tenant's
installations or decorations made prior to the Commencement Date and not
installed by Landlord. Tenant shall indemnify and hold harmless Landlord and
Landlord's Contractors from and against any and all costs, expenses, claims,
liabilities and causes of action arising out of or in connection with work
performed in the Premises by or on behalf of Tenant (but excluding work
performed by Landlord or Landlord's Contractors). Landlord is not responsible
for the function and maintenance of Tenant's Improvements which are different
than Landlord's standard improvements at the Property or improvements,
equipment, cabinets or fixtures not installed by Landlord. Such entry by Tenant
and Tenant's Contractors pursuant to this Section 5 shall be deemed to be under
all of the terms, covenants, provisions and conditions of the Lease except the
covenant to pay Rent.

6.   CONSTRUCTION REPRESENTATIVES.  Landlord's and Tenant's representatives for

                                RENEWAL OPTION

     This Rider is attached to and a part of that certain Lease Agreement dated
as of August 4, 1998, executed by and between B. O. III, LTD., a Texas limited
partnership ("Landlord"), and VIGNETTE, INC., a Delaware corporation ("Tenant).

Any capitalized term used but not defined herein shall have the meaning assigned
to it in the provisions designated in the Lease as the Supplemental Lease
Provisions.  Landlord and Tenant mutually agree as follows:

1.   If, and only if, on the Expiration Date and the date Tenant notifies
     Landlord of its intention to renew the term of this Lease (as provided
     below), (i) Tenant is not in default under this Lease, (ii) Tenant then
     occupies at least ninety percent (90%) of the Agreed Rentable Area of the
     original Premises and the Premises then consist of at least all the
     original Premises and (iii) this Lease is in full force and effect, then
     Tenant, but not any assignee or subtenant of Tenant, shall have and may
     exercise an option to renew this Lease for two (2) additional terms of
     seven (7) years each (each, a "Renewal Term") upon the same terms and
     conditions contained in this Lease with the exceptions that (x) this Lease
     shall not be further available for renewal after the second Renewal Term
     and (y) the rental for each Renewal Term shall be the "Renewal Rental
     Rate", but in no event will the Base Annual Rent be less than the Base
     Annual Rent for the last twelve (12) calendar months of the preceding term
     of the Lease. The Renewal Rental Rate is hereby defined to mean the then
     prevailing rents (including, without limitation, those similar to the Basic
     Annual Rent and Additional Rent) payable by renewal tenants having a credit
     standing substantially similar to that of Tenant, for properties of
     equivalent quality, size, utility and location as the Premises, including
     any additions thereto, located within the area described below and leased
     for a renewal term approximately equal to the Renewal Term. The Renewal
     Rental Rate will take into consideration the tenant inducements offered in
     the renewal transactions considered by Landlord in determining the Renewal
     Rental Rate. Notwithstanding the foregoing, Tenant shall not be entitled to
     exercise the second renewal option unless Tenant exercises the first
     renewal option.

2.   If Tenant desires to renew this Lease, Tenant must notify Landlord in
     writing of its intention to renew on or before the date which is at least
     nine (9) months but no more than twelve (12) months prior to the Expiration
     Date or the expiration of the first Renewal Term, as the case may be.
     Landlord shall, within the next sixty (60) days, notify Tenant in writing
     of Landlord's determination of the Renewal Rental Rate and Tenant shall,
     within the next twenty (20) days following receipt of Landlord's
     determination of the Renewal Rental Rate, notify Landlord in writing of
     Tenant's acceptance or rejection of Landlord's determination of the Renewal
     Rental Rate. If Tenant timely notifies Landlord of Tenant's acceptance of
     Landlord's determination of the Renewal Rental Rate, this Lease shall be
     extended as provided herein and Landlord and Tenant shall enter into an
     amendment to this Lease to reflect the extension of the term and changes in
     Rent in accordance with this Rider. If (i) Tenant timely notifies Landlord
     in writing of Tenant's rejection of Landlord's determination of the Renewal
     Rental Rate and does not invoke its rights under Paragraph D below, or (ii)
     Tenant does not notify Landlord in writing of Tenant's acceptance or
     rejection of Landlord's determination of the Renewal Rental Rate within
     such twenty (20) day period, this Lease shall end on the Expiration Date
     and Landlord shall have no further obligations or liability hereunder. If
     Tenant timely notifies Landlord in writing of Tenant's rejection of
     Landlord's determination of the Renewal Rental Rate and does invoke its
     rights under Paragraph D below (such notice, "Tenant's Notification"), this
     Lease shall be extended as provided herein and Landlord and Tenant shall
     enter into an amendment to this Lease to reflect the extension of the term
     and changes in Rent, with the Renewal Rental Rate determined in accordance
     with Paragraph D below.

C.   The market area with respect to which the Renewal Rental Rate will be
     determined is the southwest Austin, Texas suburban office space market.

D.   If Tenant timely invokes its rights under this Paragraph D, the following
     shall apply:

          (i)    Landlord and Tenant shall each appoint a real estate broker
     (who shall not be required to be a disinterested broker) with at least five
     (5) years experience who is familiar with rental values for properties in
     the vicinity of the Building. Each party will make the appointment no later
     than ten (10) days after receipt of Tenant's Notification. The agreement of
     the two brokers as to the Renewal Rental Rate for the Renewal Term will be
     binding upon Landlord and Tenant. If the two (2) brokers cannot agree upon
     the Renewal Rental Rate within fifteen (15) days following their
     appointment, they shall within ten (10) days thereafter agree upon a real
     estate broker (the "Independent Broker") with the qualifications set forth
     in subparagraph D(ii) below. Immediately thereafter, each of the brokers
     will submit his best estimate of the Renewal Rental Rate for the Renewal
     Term (together with a written report supporting such estimate) to the
     Independent Broker and such broker will choose between the two estimates.
     The estimate of Renewal Rental Rate chosen by the Independent Broker as the
     closest to the Renewal Rental Rate will be binding upon Landlord and
     Tenant. Notification in writing of this estimate shall be made to Landlord
     and Tenant within fifteen (15) days following the selection of the
     Independent Broker.

          (ii)   If either Tenant or Landlord fails to appoint a broker or fails
    to notify the other party of such appointment within ten (10) days after
    receipt of notice that the prescribed time for appointing the brokers has
    passed, then the other party's broker will determine the Renewal Rental Rate
    for the Renewal Term which must be reasonable within the context of the
    market. The Independent Broker must be a disinterested, reputable, qualified
    real estate broker with at least ten (10) years experience in who is
    familiar with rental values from properties in the vicinity of the Building.

          (iii)  If an Independent Broker must be chosen under the procedure set
    out above, he will be chosen on the basis objectivity and competence, not on
    the basis of his relationship with the brokers or the parties to this Lease,
    and the brokers will be so advised. Although the brokers will be instructed
    to attempt in good faith to agree upon the broker, if for any reason they
    cannot agree within the prescribed time, either Landlord or Tenant may
    require the brokers to immediately submit its top choice for the Independent
    Broker to the then highest ranking officer of the Dallas Bar Association who
    will agree to help and who has no attorney/client or other significant
    relationship to either Landlord or Tenant or the brokers. Such officer will
    have complete discretion to select the most objective and competent
    independent broker from between the choice of each of the brokers, and will
    do so within twenty (20) days after such choices are submitted to him.

          (iv)   Either Landlord or Tenant may notify the broker selected by the
    other party to demand the submission of an estimate of the Renewal Rental
    Rate or a choice of the Independent Broker as required under the procedure
    described above; and if the submission of such an estimate or choice is
    required but the other party's broker fails to comply with the demand within
    ten

                                       1
<PAGE>
 
    (10) days after receipt of such notice, then the Renewal Rental Rate or
    choice of the Independent Broker, as the case may be, selected by the other
    broker (i.e., the notifying party's broker) will be binding upon Landlord
    and Tenant.

          (v)    Landlord and Tenant shall each bear the expense, if any, of the
    broker appointed by it, and the expense of the Independent Broker and of any
    officer of the Dallas Bar Association who participates in the appraisal
    process described above will be shared equally by Landlord and Tenant.

          (vi)   If for any reason the Renewal Rental Rate has not been
    determined prior to the commencement of the Renewal Term, then during such
    Renewal Term until the Renewal Rental Rate is determined in accordance with
    the procedure described above, Tenant shall pay Basic Monthly Rent at the
    rate that is 125% of the rate of Basic Monthly Rent which applied prior to
    such Renewal Term. Later, when the Renewal Rental Rate for the Renewal Term
    is determined, an adjustment will be made between Landlord and Tenant for
    any overpayment or underpayment of the Renewal Rental Rate resulting from
    the operation of this subparagraph. Any underpayment of the Renewal Rental
    Rate for the period prior to such determination will be paid with the
    installment of Basic Monthly Rent next due after such determination, and any
    overpayment of the Renewal Rental Rate shall be applied as an offset by
    Landlord against Tenant's next maturing installments of Basic Monthly Rent.

                               EXPANSION OPTION

     This Rider is attached to and a part of that certain Lease Agreement dated
as of August 4, 1998, executed by and between B. O. III., LTD., a Texas limited
partnership ("Landlord"), and Vignette, Inc., a Delaware corporation  ("Tenant).
Any capitalized term used but not defined herein shall have the meaning assigned
to it in the provisions designated in the Lease as the Supplemental Lease
Provisions.  Landlord and Tenant mutually agree as follows:

A.   Subject to the remaining provisions of this Rider, Tenant shall have the
     option and right (the "Expansion Option") to lease from Landlord all, but
     not less than all, of the first (1st) floor of the Building not included in
     the initial Premises (the "First Floor Expansion Space"), and all, but not
     less than all, of 10,000 square feet of Agreed Rentable Area on the third
     (3rd) floor of the Building (the "Third Floor Expansion Space")
     (collectively, the "Expansion Space"). The agreed rentable area of the
     First Floor Expansion Space is 5,049 square feet. Landlord shall designate
     the location of the Third Floor Expansion Space at the time Tenant exercise
     the Expansion Option with respect to such space. Tenant shall exercise the
     Expansion Option, if at all, by delivering written notice of such exercise
     (such notice, the "Notice") on or before 5:00 p.m. December 31, 1998. If
     Tenant fails to so exercise the Expansion Option as to either the First
     Floor Expansion Space or the Third Floor Expansion Space, the Expansion
     Option with respect to such space shall be of no further force or effect.

B.   The applicable Expansion Space shall be leased to Tenant upon all terms and
     conditions of this Lease with the following exceptions:

     (a)  All Expansion Space shall be delivered to Tenant in Building shell
          condition.

     (b)  Basic Annual Rent for the applicable Expansion Space will be equal to
          the product of the Agreed Rentable Area per square foot rent
          applicable to the Premises (at the time such Basic Annual Rent is
          calculated) under Item 3 of the Basic Lease Provisions, multiplied by
          the agreed rentable area of the Expansion Space.

     (c)  Basic Monthly Rent for the Expansion Space will be equal to one-
          twelfth (1/12th) of the Basic Annual Rent for the Expansion Space.

     (d)  Basic Annual Rent and Additional Rent for the Expansion Space shall
          commence on the earlier to occur of (i) ninety (90) days after
          Landlord's receipt of the Notice; provided that such ninety (90) day
          period shall be extended by one day for each day of Landlord Delay
          (hereinafter defined), and (ii) the date that Tenant commences use of
          the Expansion Space. For purposes hereof, Landlord Delay shall mean
          each day that Landlord fails to make a submittal or take any other
          action required by Landlord within the time period provided for such
          action under the work letter executed in connection with the Expansion
          Space.

     (e)  The dates for submission of the initial space plan and construction
          plans for the leasehold improvements to be constructed in the
          Expansion Space shall be agreed to by Landlord and Tenant within five
          (5) days after Tenant elects to lease the Expansion Space.

     (f)  Tenant shall be entitled to a finish allowance equal to the product of
          (i) the per square foot Finish Allowance provided by Landlord with
          respect to the initial Premises (as set forth in Exhibit D to the
                                                           ---------       
          Lease), multiplied by (ii) the number of square feet of the Expansion
          Space, multiplied by (iii) a fraction, the numerator of which is the
          number of full calendar months which remain in the initial Lease Term
          from and after the date Basic Annual Rent commences with respect to
          the Expansion Space and the denominator of which is the number of full
          calendar months in the initial Lease Term.

     (g)  Tenant shall have no right to occupy any portion of the Expansion
          Space and in no event shall Tenant occupy the Expansion Space prior to
          (i) Substantial Completion of the leasehold improvements to be
          constructed in the Expansion Space, (ii) issuance of a certificate of
          completion or other document or permit issued by the applicable
          governmental authority authorizing Tenant's occupancy of the Expansion
          Space and (iii) Landlord's receipt of an Acceptance of Premises
          Memorandum executed by Tenant and covering the Expansion Space.

C.   Within fifteen (15) days after Landlord's receipt of the Notice, Tenant and
     Landlord will enter into a work letter substantially in the form of Exhibit
                                                                         -------
     D attached to the Lease, provided that such form shall be amended to (i)
     -
     set-forth appropriate dates, (ii) amend the finish allowance to be the
     amount of finish allowance calculated in accordance with clause (g) of
     Paragraph B of this Rider and (iii) provide for such other matters as are
     necessary to reflect the agreements of the parties with respect to the
     finish out of the Expansion Space. Pursuant to the work letter, Landlord
     shall construct or cause to be constructed improvements in the Expansion
     Space in substantial accordance with construction plans agreed to by
     Landlord and Tenant.

D.   Upon substantial completion of the Expansion Space improvements, Landlord
     and Tenant shall execute an Acceptance of Premises Memorandum in
     substantially the form of Exhibit E attached to the Lease. If Tenant
                               ---------                                  
     occupies any Expansion Space without executing the Acceptance of Premises
     Memorandum, Tenant shall be deemed to have accepted such Expansion Space
     for all purposes.

E.   Within fifteen (15) days after Landlord's receipt of the Notice, Landlord
     and Tenant will enter into an amendment to this Lease reflecting (i) the
     addition of the Expansion Space to the Premises, (ii) the increase in Basic
     Annual Rent and Additional Rent payable under this Lease, (iii) the
     increase in Tenant's Pro Rata Share Percentage and (iv) such other
     amendments as are necessary.

F.   Landlord shall not be liable for the failure to give possession of any of
     the Expansion Space by reason of holding over or retention of any third
     party tenant, tenants or occupants if such holding over or retention of
     possession is contrary to the terms and provisions of the lease of any such
     third party tenant, tenants or occupants with Landlord and Landlord has
     employed legal counsel to take reasonable steps to endeavor to evict such
     third party tenant, tenants or occupants. The Landlord shall also not be
     liable for the failure to give possession of any Expansion Space by reason
     of force majeure as defined in the Lease. Any rent otherwise due by Tenant
     with respect to such Expansion Space shall, however, be abated until
     possession is delivered to Tenant and such abatement shall constitute full
     settlement of all claims that Tenant might otherwise have against Landlord
     by reason of any failure of Landlord to timely give possession of such
     Expansion Space to Tenant during such time period as Landlord is pursuing
     eviction efforts in the manner described preceding and/or during such time
     period as such force majeure is continuing.

G.   Notwithstanding any other provision or inference herein to the contrary,
     Tenant's rights and Landlord's obligations under this Rider shall expire
     and be of no further force or effect on the earliest of (i) the expiration
     or earlier termination of the initial term of this Lease, (ii) a default by
     Tenant under this Lease, (iii) an assignment of this Lease by Tenant or
     (iv) a sublease of all or any portion of the Premises by Tenant other than

                        TENANT'S RIGHT OF FIRST REFUSAL

     This Rider is attached to and a part of that certain Lease Agreement dated
as of August 4, 1998, executed by and between B. O. III, LTD., a Texas limited
partnership ("Landlord"), and VIGNETTE, INC., a Delaware corporation ("Tenant).
Any capitalized term used but not defined herein shall have the meaning assigned
to it in the provisions designated in the Lease as the Supplemental Lease
Provisions.  Landlord and Tenant mutually agree as follows:

A.   Prior to leasing any rentable area of the Building (other than the
     Premises) (the "Right of First Refusal Space") to a prospective tenant,
     Landlord shall deliver to Tenant a written statement ("Statement") pursuant
     to which Landlord shall specify the terms and conditions upon which
     Landlord has agreed to lease the applicable Right of First Refusal Space to
     the prospective tenant, and Tenant shall have the right to lease the
     applicable Right of First Refusal Space upon the same terms and conditions;
     provided that Tenant shall pay a security deposit in connection with such
     Right of First Refusal Space equal to $4.69 per square foot of Agreed
     Rentable Area of the applicable Right of First Refusal Space. Tenant shall
     have five (5) days after receipt of the Statement within which to notify
     Landlord in writing that it desires to lease the applicable Right of First
     Refusal Space upon the terms and conditions set forth in the Statement;
     provided that Tenant shall pay a security deposit in connection with such
     Right of First Refusal Space equal to $4.69 per square foot of Agreed
     Rentable Area of the applicable Right of First Refusal Space. Failure by
     Tenant to notify Landlord within such five (5) day period shall be deemed
     an election by Tenant not to lease the applicable Right of First Refusal
     Space and Landlord shall have the right to lease such space to the
     prospective tenant upon the terms and conditions set forth in the
     Statement. If Landlord enters into such a lease with the prospective tenant
     within 120 days after the expiration of such five (5) day period, Tenant
     shall have no further rights under this Rider with respect to the Right of
     First Refusal Space covered by such lease. In the event Landlord fails to
     enter into a lease with the prospective tenant within 120 days after the
     expiration of the five (5) day period, Tenant's rights under this Rider
     with respect to such Right of First Refusal Space shall be reinstated.
     Tenant's rights under this Rider shall continue with respect to any Right
     of First Refusal Space not previously offered to Tenant.

B.   Notwithstanding any provision or inference in this Rider to the contrary,
     the Right of First Refusal shall expire and be of no further force or
     effect on the earlier of (i) the expiration or earlier termination of the
     initial term of this Lease, (ii) a default by Tenant under this Lease,
     (iii) an assignment of this Lease by Tenant, (iv) a sublease of all or any
     portion of the Premises by Tenant other than a sublease described in
     Section 11.5 of the Lease which does not give rise to Landlord's right to
     terminate the Lease with respect to such sublease, or (v) Landlord's lease
     of the Right of First Refusal Space within 120 days after the expiration of
     the five (5) day Tenant response period.

                         TENANT'S RIGHT OF OPPORTUNITY
                    (BASIC RENT EQUAL TO FAIR MARKET RENT)

     This Rider is attached to and a part of that certain Lease Agreement dated
as of August 4, 1998, executed by and between B. O. III, LTD., a Texas limited
partnership ("Landlord"), and VIGNETTE, INC., a Delaware corporation ("Tenant).
Any capitalized term used but not defined herein shall have the meaning assigned
to it in the provisions designated in the Lease as the Supplemental Lease
Provisions.  Landlord and Tenant mutually agree as follows:

A.   Prior to leasing to a third party (other than (i) the existing tenant of
     such space under the initial lease of such space by Landlord, or (ii) the
     holder of any Third Party Expansion Rights with respect to such space) any
     of the rentable area in of the Building (other than the Premises) (the
     "Opportunity Expansion Space") after the initial lease of such Opportunity
     Expansion Space by Landlord, Landlord shall deliver to Tenant a written
     statement ("Statement") setting forth (a) the location of the applicable
     Available Opportunity Expansion Space and (b) Landlord's determination of
     the Fair Market Rent (hereinafter defined) for the applicable Available
     Opportunity Expansion Space. The phrase "Available Opportunity Expansion
     Space" is hereby defined to mean Opportunity Expansion Space which is not
     subject to any expansion options, rights of refusal, rights of opportunity,
     rights of offer and other similar expansion rights pursuant to an initial
     lease of space in the Building (any and all such expansion rights, "Third
     Party Expansion Rights"). Tenant shall have fifteen (15) days after receipt
     of the Statement within which to notify Landlord in writing that it elects
     to lease the applicable Opportunity Expansion Space and whether Tenant
     agrees with Landlord's determination of the Fair Market Rent (each such
     written notice is herein referred to as a "Opportunity Notice"). If Tenant
     elects to lease the applicable Opportunity Expansion Space within such
     fifteen (15) day period, then Tenant's election shall be irrevocable. The
     Notice shall also specify whether Tenant accepts or rejects Landlord's
     determination of the Fair Market Rent. If Tenant timely notifies Landlord
     in writing of Tenant's rejection of Landlord's determination of the Fair
     Market Rent, the Fair Market Rent shall be determined in accordance with
     Paragraph B below. If Tenant does not specify in the Notice whether Tenant
     accepts or rejects Landlord's determination of the Fair Market Rent, Tenant
     shall be deemed to have accepted Landlord's determination. Failure by
     Tenant to notify Landlord within such fifteen (15) day period shall be
     deemed an election by Tenant not to lease the applicable Opportunity
     Expansion Space and Tenant's rights under this Rider with respect to such
     space shall terminate. However, Tenant's rights hereunder with respect to
     all other Opportunity Expansion Space which has not been previously offered
     to Tenant shall continue.

B.   If Tenant timely invokes its rights under this Paragraph B, the following
     shall apply:

          (i)   Landlord and Tenant shall each appoint a real estate broker (who
     shall not be required to be a disinterested broker) with at least five (5)
     years experience who is familiar with rental values for properties in the
     vicinity of the Building. Each party will make the appointment no later
     than three (3) business days after receipt of the Notice. The agreement of
     the two brokers as to the Fair Market Rent for the applicable Opportunity
     Expansion Space will be binding upon Landlord and Tenant. If the two (2)
     brokers cannot agree upon the Fair Market Rent within five (5) business
     days following their appointment, they shall within three (3) business)
     days thereafter agree upon a real estate broker (the "Independent Broker")
     with the qualifications set forth in subparagraph B(ii) below. Immediately
     thereafter, each of the brokers will submit his best estimate of the Fair
     Market Rent for the applicable Opportunity Expansion Space (together with a
     written report supporting such estimate) to the Independent Broker and such
     broker will choose between the two estimates. The estimate of Renewal
     Rental Rate chosen by the Independent Broker as the closest to the Fair
     Market Rent will be binding upon Landlord and Tenant. Notification in
     writing of this estimate shall be made to Landlord and Tenant within three
     (3) business days following the selection of the Independent Broker.

          (ii)  If either Tenant or Landlord fails to appoint a broker or fails
     to notify the other party of such appointment within two (2) business days
     after receipt of notice that the prescribed time for appointing the brokers
     has passed, then the other party's broker will determine the Fair Market
     Rent for the Opportunity Expansion Space which must be reasonable within
     the context of the market. The Independent Broker must be a disinterested,
     reputable, qualified real estate broker with at least ten (10) years
     experience in who is familiar with rental values from properties in the
     vicinity of the Building.

          (iii) If an Independent Broker must be chosen under the procedure set
     out above, he will be chosen on the basis objectivity and competence, not
     on the basis of his relationship with the brokers or the parties to this
     Lease, and the brokers will be so advised. Although the brokers will be
     instructed to attempt in good faith to agree upon the broker, if for any
     reason they cannot agree within the prescribed time, either Landlord or
     Tenant may require the brokers to immediately submit its top choice for the
     Independent Broker to the then highest ranking officer of the Travis County
     Bar Association who will agree to help and who has no attorney/client or
     other significant relationship to either Landlord or Tenant or the brokers.
     Such officer will have complete discretion to select the most objective and
     competent independent broker from between the choice of each of the
     brokers, and will do so within twenty (20) days after such choices are
     submitted to him.

          (iv)  Either Landlord or Tenant may notify the broker selected by the
    other party to demand the submission of an estimate of the Fair Market Rent
    or a choice of the Independent Broker as required under the procedure
    described above; and if the submission of such an estimate or choice is
    required but the other party's broker fails to comply with the demand within
    three (3) business days after receipt of such notice, then the Renewal
    Rental Rate or choice of the Independent Broker, as the case may be,
    selected by the other broker (i.e., the notifying party's broker) will be
    binding upon Landlord and Tenant.

          (v)   Landlord and Tenant shall each bear the expense, if any, of the
    broker appointed by it, and the expense of the Independent Broker and of any
    officer of the Travis County Bar Association who participates in the
    appraisal process described above will be shared equally by Landlord and
    Tenant.

         (vi)   If for any reason the Fair Market Rent has not been determined
     prior to the rent commencement date for the applicable Opportunity
     Expansion Space, then until the Fair Market Rent is determined in
     accordance with the procedure described above, Tenant shall pay Basic
     Monthly Rent at the rate payable under the Lease for the initial Premises.
     Later, when the Fair Market Rent for the Opportunity Expansion Space is
     determined, an adjustment will be made between Landlord and Tenant for any
     overpayment or underpayment of the Fair Market Rent resulting from the
     operation of this subparagraph. Any underpayment of the Fair Market Rent
     for the period prior to such determination will be paid with the
     installment of Basic Monthly Rent next due after such determination, and
     any overpayment of the Fair Market Rent shall be applied as an offset by
     Landlord against Tenant's next maturing installments of Basic Monthly Rent.

C.   The applicable Opportunity Expansion Space shall be leased to Tenant upon
     all terms and conditions of this Lease with the following exceptions:

     (a)  All Opportunity Expansion Space shall be delivered to Tenant in "as
          is" condition.

     (b)  The term of the Lease for the applicable Opportunity Expansion Space
          will be (a) with respect to any Opportunity Expansion Space which
          contains 10,000 square feet of Agreed Rentable Area or less, the
          greater of (X) the remaining term of the Lease or (Y) three (3) years
          from the d Rent Commencement Date (hereinafter defined) for such
          space, and (b) with respect to any Opportunity Expansion Space
          containing in excess of 10,000 square feet of Agreed Rentable Area,
          the greater of (X) the remaining term of the Lease of (Y) four (4)
          years from the d Rent Commencement Date for such space.

     (c)  Basic Annual Rent for the applicable Opportunity Expansion Space will
          be equal to the Fair Market Rent, which is hereby defined to mean the
          then prevailing rents similar to the Basic Annual Rent payable by
          tenants for premises within the Project of equivalent quality, size,
          and utility as the applicable Opportunity Expansion Space and leased
          for a term approximately equal to the lease term for the applicable
          Opportunity Expansion Space, as the case may be.  The Fair Market Rent
          will take into consideration, and Tenant shall be entitled to, only
          the tenant inducements (inclusive of the finish allowance) agreed to
          in the transactions considered by Landlord in determining the Fair
          Market Rent.

     (d)  The Basic Monthly Rent for the agreed rentable area of the Opportunity
          Expansion Space will be equal to one-twelfth (1/12th) of the Basic
          Annual Rent for the applicable Opportunity Expansion Space.

     (e)  The dates for submission of the initial space plan and construction

                                August 15, 1998

Vignette Corporation
3410 Far West Boulevard, Suite 300
Austin, Texas 78731
Attention: Greg Peters

     RE:  Letter Amendment to "Prism" Development and Marketing Agreement
          between Vignette Corporation ("Vignette") and CNET, Inc. ("CNET"),
          dated as of July 19, 1996, as amended (the "Agreement")

Dear Greg:

     As we have discussed, CNET and National Broadcasting Company, Inc. ("NBC")
have agreed to form a separate joint venture entity to operate the Snap!
Internet portal service (the "Snap Service"), which is currently operated as a
division of CNET. Initially, the joint venture will be owned 81% by CNET and 19%
by NBC Multimedia, Inc., which is a wholly-owned subsidiary of NBC, but NBC
Multimedia, Inc. will have an option to acquire majority ownership of the joint
venture.

     Legally, our transaction with NBC will involve the creation of a limited
liability company, Snap! LLC (the "LLC"), and a contribution of Snap assets from
CNET into the LLC. This transaction is expected to close on or around June 30,
1998 (the "Closing"). In order to avoid any ambiguity concerning the application
of the Agreement to the LLC, we are asking you to execute this Letter Amendment
to indicate your agreement to the provisions set forth below. Capitalized terms
used in this Letter Amendment that are not otherwise defined have the meanings
given to such terms in the Agreement.

     1.   Snap Site.  The "Snap Site" means (a) the default version of the Snap
          ---------                                                       
Service, which is currently accessible through "http://www.snap.com" and
includes all URL's that begin with the prefix "http://www.snap.com" (the
"Default Edition"); (b) any co-branded editions of the foregoing that contain
substantially the same content and features as the Default Edition and are
developed for third party distribution partners, for example URL's that begin
with the prefix "http://mci.snap.com"; and (c) any successors to or replacements
of the foregoing (as long as all such sites contain substantially the same
contents and features). The Snap Site may be operated from one or more servers,
including servers operated on behalf of the LLC by third parties, provided the
LLC remains responsible for the content hosted by the servers.

     2.   Snap Internal Use.  Effective upon the Closing, and subject to CNET's
          -----------------                                             
execution of the assignment of Patent Rights as specified in Section 6(a) of
this Letter Agreement, any Use of Intellectual Property by the LLC for internal
development purposes or for internal production purposes in connection with the
Snap Site ("Snap Internal Use") will constitute "Internal Use" at a single
Internet site for purposes of the Agreement. Accordingly, effective upon the
Closing:

          (a)  the LLC will be entitled to Use the Systems in object code form
     only pursuant to the perpetual, non-exclusive, royalty-free license granted
     to CNET in Section 4.2(a) of the

                                       1
<PAGE>
 
     Agreement, but only for Snap Internal Use, and the LLC will be entitled to
     enforce such rights directly against Vignette, as if the LLC were a party
     to the Agreement; and

          (b)  subject to the other terms and conditions of this Letter
     Amendment, the LLC shall not be required to pay license fees or other
     royalties to Vignette in respect of the rights to Use the Systems granted
     hereunder; and

          (c)  the LLC hereby grants to Vignette the license described in
     Section 4.1(b) of the Agreement (as amended) and the related rights
     described in Section 4.2(c) of the Agreement, and Vignette will be entitled
     to enforce such rights directly against the LLC, as if the LLC were a party
     to the Agreement; and

          (d)  the LLC hereby agrees to be bound by the confidentiality
     provisions set forth in Section 11 of the Agreement, and Vignette will be
     entitled to enforce such provisions directly against the LLC, as if the LLC
     were a party to the Agreement.

     3.   Limitations on Use.  Notwithstanding any contrary provisions of the
          ------------------                                             
Agreement or this Letter Amendment, the LLC will not have the right to receive
or Use the source code for the Systems (the "Source Code"), but CNET will have
the right to Use the Source Code (to the full extent permitted under the
Agreement) for the benefit of the LLC and to deliver to the LLC object code
versions of any Derivatives of the Systems developed by CNET for the LLC, and
the LLC will have the right to Use the object code versions of such Derivatives
for Snap Internal Use as contemplated by Section 2(a) of this Letter Amendment.
The intention of the parties in providing such rights is to allow the LLC to
engage CNET to modify or improve the Systems if the prioritized needs of the LLC
for Snap Internal Use are inconsistent with standard System features and
Vignette's development schedule. Alternatively, if Vignette and the LLC agree,
the LLC may engage Vignette to perform any necessary modifications or
improvements to the Source Code. The LLC will use commercially reasonable
efforts to plan for a transition to commercially available versions of the
Systems (or other software systems) on or before the Minority Ownership Date (as
defined below) and to limit, to the extent commercially reasonable, any
modifications to the Source Code and any use of customized versions of the
Systems after the Minority Ownership Date.

     4.   Required Payments after the Minority Ownership Date.
          --------------------------------------------------- 

          (a)  The date on which CNET first owns less than 50% of the
     outstanding equity interests in the LLC is referred to as the "Minority
     Ownership Date."

          (b)  Any Systems that the LLC is using immediately prior to the
     Minority Ownership Date and that the LLC desires to continue using after
     the Minority Ownership Date are referred to as the "Selected Systems";
     provided that (i) the Selected Systems will include only Vignette's
     "StoryServer" Systems and any successors thereto and (ii) the Selected
     Systems must be sized in a manner that is fair and reasonable to Vignette
     and to the LLC in light of the scope of the LLC's operations on the
     Minority Ownership Date. Within 30 days after the Minority Ownership Date,
     the LLC will notify Vignette of the proposed Selected Systems, to include
     the number of copies, the number of servers, the location of the servers,
     the URL's hosted, and the number of pages served per day. At Vignette's
     request, which must be delivered within 15 days after such notice, CNET,
     the LLC and Vignette will cooperate reasonably and in good faith to examine
     the configuration of the Selected Systems in light of the operations of the
     LLC and to determine whether such sizing is fair and reasonable for the
     LLC's scope of operations. Absent a contrary agreement between the LLC and
     Vignette, if the sizing and use of the Selected Systems is within

                                       2
<PAGE>
 
     15% of Vignette's standard published guidelines for sizing and use of
     installations of similar Systems on similar sites, then the Selected
     Systems will be considered fair and reasonable for purposes of this
     paragraph.

          (c)  The LLC's license to Use the Selected Systems, as contemplated by
     Section 2(a) of this Letter Amendment, will continue after the Minority
     Ownership Date on a royalty-free basis, but the LLC will be required to pay
     for any incremental licenses associated with increases in the size of the
     Selected Systems after the Minority Ownership Date. In calculating the
     incremental license fees, it will be assumed that the LLC has paid cash for
     one or more full license(s) to the Selected Systems. Pricing for such
     incremental license will be at least as favorable as the most favorable
     terms then being offered by Vignette to any similarly situated end user
     customer with respect to similar Systems, based on similar volumes and
     usage profiles.

          (d)  Beginning on the Minority Ownership Date, the LLC will be
     required to purchase a contract for support, maintenance and update
     services (a "Support Contract") for the Selected Systems and, to the extent
     applicable, any incremental licenses associated with increased sizing for
     the Selected Systems, or else the LLC will not be entitled to receive any
     such support, maintenance or update services from Vignette. Pricing and
     other terms applicable to any such Support Contract will be at least as
     favorable as the most favorable terms then being offered by Vignette to any
     similarly situated end user customer with respect to the Selected Systems,
     which will be determined by (a) calculating the most favorable price then
     being offered by Vignette for the same or similar products as those
     comprising the Selected Systems (and such incremental licenses) and (b)
     applying the most favorable percentage then being offered by Vignette for
     support, maintenance and update services for the Selected Systems. Volume
     discounts or other promotions or incentives shall apply to the LLC, and to
     the calculation of pricing and percentages described above in this Section
     4(d), as they apply to other Vignette customers.

will choose the escrow agent, and the retention and release of the Source Code
and related documentation will be governed by a standard software escrow
agreement reasonably acceptable to both parties and the escrow agent,
substantially in the form attached hereto as Attachment 1 (the "Escrow
Agreement"). Upon release, pursuant to the terms of the Escrow Agreement, the
LLC will have a royalty-free license to use the Source Code and related
documentation for Snap Internal Use only. Following the initial creation of the

escrowed Source Code and documentation at least four times each year until
termination of the Escrow Agreement. Vignette will pay the setup and base
maintenance fees charged by the escrow agent, and the LLC will pay the per-
beneficiary fees charged by the escrow agent for escrow of the Source Code and
related documentation as contemplated by this paragraph and the Escrow
Agreement.

                          PREFERRED ESCROW AGREEMENT

                     Account Number ______________________


This Agreement is effective __________________, 1998 among Data Securities
International, Inc. ("DSI"), Vignette Corporation ("Depositor") and Snap! LLC
("Preferred Beneficiary"), who collectively may be referred to in this Agreement
as "the parties."

A.   Depositor and Preferred Beneficiary have entered or will enter into a
license agreement regarding certain proprietary technology of Depositor
(referred to in this Agreement as "the license agreement").

B.   Depositor desires to avoid disclosure of its proprietary technology except
under certain limited circumstances.

C.   The availability of the proprietary technology of Depositor is critical to
Preferred Beneficiary in the conduct of its business and, therefore, Preferred
Beneficiary needs access to the proprietary technology under certain limited
circumstances.

D.   Depositor and Preferred Beneficiary desire to establish an escrow with DSI
to provide for the retention, administration and controlled access of the
proprietary technology materials of Depositor.

E.   The parties desire this Agreement to be supplementary to the license
agreement pursuant to 11 United States Code, Section 365(n).


ARTICLE 1  --  DEPOSITS

1.1  Obligation to Make Deposit.  Upon the signing of this Agreement by the
     --------------------------                                            
parties, Depositor shall deliver to DSI the proprietary information and other
materials ("deposit materials") required to be deposited by the license
agreement or, if the license agreement does not identify the materials to be
deposited with DSI, then such materials will be identified on an Exhibit A.  If
Exhibit A is applicable, it is to be prepared and signed by Depositor and
Preferred Beneficiary.  DSI shall have no obligation with respect to the
preparation, signing or delivery of Exhibit A.

1.2  Identification of Tangible Media.  Prior to the delivery of the deposit
     --------------------------------                                       
materials to DSI, Depositor shall conspicuously label for identification each
document, magnetic tape, disk, or other tangible media upon which the deposit
materials are written or stored. Additionally, Depositor shall complete Exhibit
B to this Agreement by listing each such tangible media by the item label
description, the type of media and the quantity.  The Exhibit B must be signed
by Depositor and delivered to DSI with the deposit materials.  Unless and until
Depositor makes the initial deposit with DSI, DSI shall have no obligation with
respect to this Agreement, except the obligation to notify the parties regarding
the status of the deposit account as required in Section 2.2 below.

<PAGE>
 
1.3  Deposit Inspection.  When DSI receives the deposit materials and the
     ------------------                                                  
Exhibit B, DSI will conduct a deposit inspection by visually matching the
labeling of the tangible media containing the deposit materials to the item
descriptions and quantity listed on the Exhibit B.  In addition to the deposit
inspection, Preferred Beneficiary may elect to cause a verification of the
deposit materials in accordance with Section 1.6 below.

1.4  Acceptance of Deposit.   At completion of the deposit inspection, if DSI
     ---------------------                                                   
determines that the labeling of the tangible media matches the item descriptions
and quantity on Exhibit B, DSI will date and sign the Exhibit B and mail a copy
thereof to Depositor and Preferred Beneficiary.  If DSI determines that the
labeling does not match the item descriptions or quantity on the Exhibit B, DSI
will (a) note the discrepancies in writing on the Exhibit B; (b) date and sign
the Exhibit B with the exceptions noted; and (c) provide a copy of the Exhibit B
to Depositor and Preferred Beneficiary.  DSI's acceptance of the deposit occurs
upon the signing of the Exhibit B by DSI.  Delivery of the signed Exhibit B to
Preferred Beneficiary is Preferred Beneficiary's  notice that the deposit
materials have been received and accepted by DSI.

1.5  Depositor's Representations.  Depositor represents as follows:
     ---------------------------                                   

     a.   Depositor lawfully possesses all of the deposit materials deposited
          with DSI;

     b.   With respect to all of the deposit materials, Depositor has the right
          and authority to grant to DSI and Preferred Beneficiary the rights as
          provided in this Agreement;

     c.   The deposit materials are not subject to any lien or other
          encumbrance;

     d.   The deposit materials consist of the proprietary information and other
          materials identified either in the license agreement or Exhibit A, as
          the case may be; and

     e.   The deposit materials are readable and useable in their current form
          or, if the deposit materials are encrypted, the decryption tools and
          decryption keys have also been deposited.

1.6  Verification.  Preferred Beneficiary shall have the right, at Preferred
     ------------                                                           
Beneficiary's expense, to cause a verification of any deposit materials.  A
verification determines, in different levels of detail, the accuracy,
completeness, sufficiency and quality of the deposit materials.  If a
verification is elected after the deposit materials have been delivered to DSI,
then only DSI, or at DSI's election an independent person or company selected
and supervised by DSI, may perform the verification.

1.7  Deposit Updates.  Unless otherwise provided by the license agreement,
     ---------------                                                      
Depositor shall update the deposit materials within 60 days of each release of a
new version of the product which is subject to the license agreement.  Such
updates will be added to the existing deposit.  All deposit updates shall be
listed on a new Exhibit B and the new Exhibit B shall be signed by Depositor.
Each Exhibit B will be held and maintained separately within the escrow account.
An independent record will be created which will document the activity for each
Exhibit B.  The processing of all deposit updates shall be in accordance with
Sections 1.2 through 1.6 above.  All references in this Agreement to the deposit
materials shall include the initial deposit materials and any updates.

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

                          SOFTWARE LICENSE AGREEMENT
 
     This Software License Agreement ("Agreement") is effective April 6, 1998
(the "Effective Date") by and between Net Perceptions, Inc., ("NPI) a Delaware
corporation having its principal place of business at 11200 West 78/th/ Street,
Eden Prairie, Minnesota 55344, and Vignette Corporation, ("VIGNETTE"), a
Delaware corporation having its principal place of business at One Far West
Plaza, 3410 Far West Plaza Boulevard, Suite 300, Austin, Texas 78731. The
parties agree:

     NPI is the developer, manufacturer, distributor and licensor of a certain
software application product, currently known as the GroupLens Recommendation
Engine, that enables businesses to foster 1-to-1 customer relationships by
tailoring web sites to deliver specific and meaningful content based on user
preferences ("GLRE").

     VIGNETTE is the developer, manufacturer and distributor of a certain
software product, currently known as Story Server, that delivers collaborative
content management with dynamic content application server ("SS").

     In order to enhance its ability to offer advanced personalization
functionality to end-users, VIGNETTE desires to license certain elements of GLRE
to be bundled with, and integrated into, the next major release of SS and,
during the effective term of this Agreement, any and all major or minor releases
thereof) (the "Integrated Product").

     VIGNETTE desires NPI to develop a derivative of GLRE ("GLE") according to
the GLE Specifications (as defined in Section 1.1 and Exhibit A), and to license
GLE to VIGNETTE for distribution solely as a component of, or in conjunction
with, the Integrated Product.

     NPI desires to develop GLE and to grant VIGNETTE certain limited license
rights under GLE for the sole purpose of VIGNETTE marketing and sublicensing GLE
in conjunction with the Integrated Product.

1.   THE GLE AND THE INTEGRATED PRODUCT

     1.1  The Specifications. The parties agree that GLE will be developed by
          ------------------
NPI according to the written specification ("Integrated Product Specification")
appended hereto as Exhibit A. The parties further agree that GLE will be
integrated into SS by Vignette to form the Integrated Product according to the
Integrated Product Specifications.

     1.2  Development and Delivery. NPI will use its best efforts to develop GLE
          ------------------------
in conformance with the GLE Specification and deliver two (2) object code copies
of the completed GLE no later than May 8, 1998 ("Initial Deliverable Date"). In
addition, all GLE feature work will be completed and delivered no later than
April 10, 1998.

     1.3  Updates. NPI will use its commercially reasonable efforts to deliver
          -------
to VIGNETTE two (2) object code copies of any and all updates, upgrades, new
releases, bug fixes of GLE that enhance GLE functionality to the extent that
existing GLE functionality is modified through the enhancement of GLRE (the
"Subsequent Deliverables") within thirty (30) business days of NPI's commercial
release of any and all major releases of GLRE occurring during the term of this
Agreement. All Subsequent Deliverables will be included within the licenses
granted hereunder; provided, however, that the parties expressly agree that
NPI's obligation to deliver Subsequent Deliverables, and VINGETTE'S rights
thereunder pursuant to this Agreement, are strictly limited to modifications,
upgrades, new releases and bug fixes to the specific functions detailed in the
GLE Specification. For purposes of this Agreement, "GLE" includes any and all
Subsequent Deliverables.

2.   APPOINTMENT AND AUTHORITY OF VIGNETTE

     2.1  Appointment of VIGNETTE.  Subject to the terms and conditions of this
          -----------------------
Agreement and to the timely payment in full of all moneys due and payable
hereunder, NPI hereby appoints VIGNETTE to act as a worldwide non-exclusive
reseller of NPI for GLE and grants the licenses under GLE granted herein, and
VIGNETTE hereby accepts such appointment.

     2.2  The rights granted VIGNETTE pursuant to this Agreement are subject to
the following conditions:

          (a)  The sublicensing rights granted to VIGNETTE pursuant to this
               Agreement are expressly subject 
<PAGE>
 
               to the condition that GLE be sublicensed solely to VIGNETTE
               Customers (as defined in Section 5.3) and for use solely as a
               component of, or in conjunction with, the Integrated Product.

          (b)  VIGNETTE will not price GLE as a separate software component.

          (c)  The user documentation provided by VIGNETTE with the Integrated
               Product to Sublicensees will describe the permitted use of each
               sublicensed copy of GLE solely to be used on one (1) Site (as
               defined in Section 2.2(e)) and will further limit the use of each
               such sublicensed copy of GLE to a maximum of ***** Registered
               Users (as defined Section 2.2(d)). NPI will provide reasonable
               and mutually-agreed assistance to VIGNETTE in developing the
               content of the GLE portion of the Integrated Product
               documentation.

          (d)  For purposes of this Agreement, "Registered Users" will mean the
               total number of individual users registered on GLE.

          (e)  For purposes of this Agreement, "Site" will mean a set of web
               pages that all have the same hostname component of the Universal
               Resource Locator.

          (f)  The documentation will state that the Integrated Product will not
               allow any Sublicensee (as defined in Section 5.4) to have more
               than ***** Registered Users and will provide information
               regarding the opportunity to license GLRE directly from NPI at
               NPI's then prevailing standard license fees (an "Upgrade").

          (g)  VIGNETTE will not (i) market GLE, except in object code form and
               as a part of the Integrated Product, supplied in conjunction
               therewith, to VIGNETTE Customers for their own internal purposes,
               (ii) modify, reverse engineer or decompile GLE or GLRE, (iii)
               remove any of NPI's proprietary copyright notices or legends that
               are in compliance with Section 5.2 below, (iv) except as
               otherwise provided hereunder, make any copies of GLE, except for
               one (1) object code copy of GLE for each copy of the Integrated
               Product to be delivered to each Sublicensee pursuant to the
               Sublicense Agreement, and (v) except as otherwise expressly
               provided herein, sublicense, assign or otherwise transfer its
               rights under this Section 2.

3.   DEVELOPMENT AND DEMONSTRATION LICENSE

     3.1  Development and Demonstration License Grant.  NPI hereby grants at no
          -------------------------------------------                          
additional charge to VIGNETTE a nonexclusive, nontransferable right to use
object code copies of GLE solely for the purpose of developing, demonstrating,
testing, and supporting the Integrated Product and not for any other internal
productive purposes (the "Development and Demonstration License").

4.   COMPATIBILITY TESTING LICENSE

confidentiality, (iii) independently developed by one party by employees without
access to the Confidential Information of the other, (iv) known to the recipient

                                       6
<PAGE>
 
     2.1   The outstanding principal amount of the Loan, together with interest
thereon precomputed at the rate of twelve (12%) percent per annum, shall be due
and payable in six (6) equal monthly installments of interest only, payable on
the first day of each month, followed by thirty (30) equal monthly installments
of principal and interest, payable on the first day of each month , to and
including the Maturity Date (each, a "Payment Date").  If any payment under the
Note(s) shall be payable on a day other than a business day, then such payment
shall be due and payable on the next succeeding business day.

     2.2   Borrower shall have the option to prepay the Loan, in whole or in
part, after 12 months from the Closing Date by paying the principal amount
thereon together with all accrued and unpaid interest with respect to such
principal amount, as of the date of such prepayment, without premium. In the
event Borrower prepays the Note(s) within 12 months from the Closing Date
hereof, Borrower shall pay the principal amount together with all accrued and
unpaid interest and a prepayment premium equal to 1% of the then outstanding
principal amount.

of time from the date of this Agreement through the end of time that any
principal is outstanding on the Note(s)), which amount of interest exceeds
interest calculated at the Maximum Rate on said principal chargeable over said
period of time, then such excess interest actually paid by Borrower shall be
applied first, to the payment of principal outstanding on the Note(s); second,
after all principal is repaid, to the payment of Lender's out of pocket costs,
expenses, and professional fees which are owed by Borrower to Lender under this
Agreement or the Loan Documents; and third, after all principal, costs,
expenses, and professional fees owed by Borrower to Lender are repaid, the
excess (if any) shall be refunded to Borrower, and the effective rate of
interest will be automatically reduced to the Maximum Rate.

           (b)   In the event any interest is not paid when due hereunder,
     delinquent interest shall be added to principal and shall bear interest on
     interest, compounded at the rate set forth in Section 2.1.

           (c)   Upon and during the continuation of an Event of Default
     hereunder, all Secured Obligations, including principal, interest,
     compounded interest, and professional fees, shall bear interest at a rate
     per annum equal to the rate set forth in Section 2.1. plus five percent
     (5%) per annum ("Default Rate").

SECTION 3.  SECURITY INTEREST

     As security for the prompt, complete and indefeasible payment when due
(whether at stated payment dates or otherwise) of all the Secured Obligations

hypothecates and transfers to Lender for security purposes only, and hereby
grants to Lender a security interest in, all of Borrower's right, title

                                       9
<PAGE>
 
     Borrower covenants and agrees as follows at all times while any of the
Secured Obligations remain outstanding:

     6.1   Borrower shall furnish to Lender the financial statements listed
hereinafter, each prepared in accordance with generally accepted accounting
principles consistently applied (the "Financial Statements"):

           (a)   as soon as practicable (and in any event within thirty (30)
     days) after the end of each month, unaudited interim financial statements
     as of the end of such month (prepared on a consolidated and consolidating
     basis, if applicable), including balance sheet and related statements of
     income and cash flows accompanied by a report detailing any material
     contingencies (including the commencement of any material litigation by or
     against Borrower) or any other occurrence that could reasonably be expected
     to have a Material Adverse Effect, all certified by Borrower's Chief
     Executive Officer or Chief Financial Officer to be true and correct;

           (b)   as soon as practicable (and in any event within ninety (90)
     days) after the end of each fiscal year, unqualified audited financial
     statements as of the end of such year (prepared on a consolidated and
     consolidating basis, if applicable), including balance sheet and related
     statements of income and cash flows, and setting forth in comparative form
     the corresponding figures for the preceding fiscal year, certified by a
     firm of independent certified public accountants selected by Borrower and
     reasonably acceptable to Lender, accompanied by any management report from
     such accountants;

           (c)   promptly after the sending or filing thereof, as the case may
     be, copies of any proxy statements, financial statements or reports which
     Borrower has made available to its shareholders and copies of any regular,
     periodic and special reports or registration statements which Borrower
     files with the Securities and Exchange Commission or any governmental
     authority which may be substituted therefor, or any national securities
     exchange; and

           (d)   promptly, any additional information, financial or otherwise
     (including, but not limited, to tax returns and names of principal
     creditors) as Lender reasonably believes necessary to evaluate Borrower's
     continuing ability to meet its financial obligations.

     6.2   Borrower shall permit any authorized representative of Lender and its
attorneys and accountants on reasonable notice to inspect, examine and make
copies and abstracts of the books of account and records of Borrower at
reasonable times during normal business hours.  In addition, such representative
of Lender and its attorneys and accountants shall have the right to meet with
management and officers of the Company to discuss such books of account and
records.

     6.3   Borrower will from time to time execute, deliver and file, alone or
with Lender, any financing statements, security agreements or other documents;
procure any instruments or documents as may be requested by Lender; and take all
further action that may be necessary or desirable, or that Lender may request,
to confirm, perfect, preserve and protect the security interests intended to be
granted hereby, and in addition, and for such purposes only, Borrower hereby
authorizes Lender to execute and deliver on behalf of Borrower and to file such

                                       10
<PAGE>
 
financing statements, security agreement and other documents without the
signature of Borrower either in Lender's name or in the name of Borrower as
agent and attorney-in-fact for Borrower. The parties agree that a carbon,
photographic or other reproduction of this Agreement shall be sufficient as a
financing statement and may be filed in any appropriate office in lieu thereof.

     6.4   Borrower shall protect and defend Borrower's title as well as the
interest of the Lender against all persons claiming any interest adverse to
Borrower or Lender and shall at all times keep the Collateral free and clear
from any legal process, liens or encumbrances whatsoever (except any placed
thereon by Lender) and shall give Lender immediate written notice thereof.

     6.5   Without Lender's prior written consent, Borrower shall not (a) grant
any material extension of the time of payment of any of the Receivables, (b) to
any material extent, compromise, compound or settle the same for less than the
full amount thereof, (c) release, wholly or partly, any Person liable for the
payment thereof, or allow any credit or discount whatsoever thereon other than
trade discounts granted in the ordinary course of business of Borrower.

     6.6   Borrower shall maintain and protect its properties, assets and
facilities, including without limitation, its Equipment and Fixtures, in good
order and working repair and condition (taking into consideration ordinary wear
and tear) and from time to time make or cause to be made all necessary and
proper repairs, renewals and replacements thereto and shall competently manage
and care for its property in accordance with prudent industry practices.

     6.7   Borrower shall not merge with and into any other entity; or sell or
convey all or substantially all of its assets or stock to any other person or
entity without notifying Lender a minimum of thirty (30) days prior to the
closing date and requesting Lender's consent to the assignment of all of
Borrower's Secured Obligations hereunder to the successor entity in form and
substance satisfactory to Lender.  In the event Lender does not consent to such
assignment the parties agree Borrower shall prepay the Loan in accordance with
Section 2.2 hereof.

     6.8   Borrower shall not, without the prior written consent of Lender, such
consent not to be unreasonably withheld, declare or pay any cash dividend or
make a distribution on any class of stock, other than pursuant to employee
repurchase plans upon an employee's death or termination of employment or
transfer, sell, lease, lend or in any other manner convey any equitable,
beneficial or legal interest in any material portion of the assets of Borrower
(except inventory sold in the normal course of business).

     6.9   Upon the request of Lender, Borrower shall, during business hours,
make the Inventory and Equipment available to Lender for inspection at the place
where it is normally located and shall make Borrower's log and maintenance
records pertaining to the Inventory and Equipment available to Lender for
inspection. Borrower shall take all action necessary to maintain such logs and
maintenance records in a correct and complete fashion.

     6.10  Borrower covenants and agrees to pay when due, all taxes, fees or
other charges of any nature whatsoever (together with any related interest or
penalties) now or hereafter imposed or assessed against Borrower, Lender or the
Collateral or upon Borrower's ownership, possession, use, operation or
disposition thereof or upon Borrower's rents, receipts

                                       11
<PAGE>
 
or earnings arising therefrom. Borrower shall file on or before the due date
therefor all personal property tax returns in respect of the Collateral.
Notwithstanding the foregoing, Borrower may contest, in good faith and by
appropriate proceedings, taxes for which Borrower maintains adequate reserves
therefor.

     6.11  Borrower shall not relocate any item of the Collateral (other than
sale of inventory in the ordinary course of business) except: (i) with the prior
written consent of the Lender not to be unreasonably withheld; and (ii) if such
relocation shall be within the continental United States. If permitted to
relocate Collateral pursuant to the foregoing sentence, unless otherwise agreed
in writing by Lender, Borrower shall first (a) cause to be filed and/or
delivered to the Lender all Uniform Commercial Code financing statements,
certificates or other documents or instruments necessary to continue in effect
the perfected security interest of the Lender in the Collateral, and (b) have
given the Lender no less than thirty (30) days prior written notice of such
relocation.

     6.12  Borrower shall not redeem any preferred stock as long as any Advance
remains outstanding.

     6.13  Borrower shall not sell, transfer, assign, hypothecate or otherwise
encumber its Intellectual Property without Lender's prior written consent.

     7.5   ABSENCE OF EVENTS OF DEFAULTS.  As of the Closing Date or the Advance

time, the giving of notice, or both) constitute an Event of Default under this

<PAGE>
 
     8.4   Borrower shall make an assignment for the benefit of creditors, or
shall admit in writing its inability to pay its debts as they become due, or
shall file a voluntary petition in bankruptcy, or shall file any petition or
answer seeking for itself any reorganization, arrangement, composition,
readjustment, liquidation, dissolution or similar relief under any present or
future statute, law or regulation pertinent to such circumstances, or shall seek

liquidator of Borrower or of all or any substantial part (33-1/3% or more) of
the properties of Borrower; or Borrower or its directors or majority

Borrower; or

     8.5   Sixty (60) days shall have expired after the commencement of an
action by or against Borrower seeking reorganization, arrangement, composition,
readjustment, liquidation, dissolution or similar relief under any present or

Borrower being stayed; or a stay of any such order or proceedings shall
thereafter be set aside and the action setting it aside shall not be timely
appealed; or Borrower shall file any answer admitting or not contesting the
material allegations of a petition filed against Borrower in any such
proceedings; or the court in which such proceedings are pending shall enter a
decree or order granting the relief sought in any such proceedings; or

that has not been bonded or stayed on appeal within thirty (30) days; or

     8.9   The occurrence of any material default under the Senior Loan
Documents; or

SECTION 9.  REMEDIES

     Upon the occurrence of any one or more Events of Default, Lender, at its
option, may declare the Note and all of the other Secured Obligations to be
accelerated and immediately due and payable (provided, that upon the occurrence
of an Event of Default of the type described in Sections 8.4 or 8.5, the Note(s)
and all of the other Secured Obligations shall automatically be accelerated and
made due and payable without any further act), whereupon the unpaid principal of
and accrued interest on such Note(s) and all other outstanding Secured
Obligations shall become immediately due and payable, and shall thereafter bear
interest at the Default Rate set forth in, and calculated according to, Section
2.3 (c) of this Agreement. Lender may exercise all rights and remedies with
respect to the Collateral under the Loan Documents or otherwise available to it
under applicable law, including the right to release, hold or otherwise dispose
of all or any part of the Collateral and the right to occupy, utilize, process
and commingle the Collateral.
 

                                       14
<PAGE>
 
     Upon the happening and during the continuance of any Event of Default,
Lender may then, or at any time thereafter and from time to time, apply,
collect, sell in one or more sales, lease or otherwise dispose of, any or all of
the Collateral, in its then condition or following any commercially reasonable
preparation or processing, in such order as Lender may elect, and any such sale
may be made either at public or private sale at its place of business or
elsewhere. Borrower agrees that any such public or private sale may occur upon
five (5) calendar days' prior written notice to Borrower. Lender may require
Borrower to assemble the Collateral and make it available to Lender at a place
designated by Lender which is reasonably convenient to Lender and Borrower. The
proceeds of any sale, disposition or other realization upon all or any part of
the Collateral shall be distributed by Lender in the following order of
priorities:

     First, to Lender in an amount sufficient to pay in full Lender's costs and
     professionals' and advisors' fees and expenses;

     Second, to Lender in an amount equal to the then unpaid amount of the
     Secured Obligations in such order and priority as Lender may choose in its
     sole discretion; and

     Finally, upon payment in full of all of the Secured Obligations, to
     Borrower or its representatives or as a court of competent jurisdiction may
     direct.

     Lender shall be deemed to have acted reasonably in the custody,
preservation and disposition of any of the Collateral if it complies with the
obligations of a secured party under Section 9207 of the UCC.

     Lender's rights and remedies hereunder are subject to the terms of the
Subordination Agreement.

SECTION 10.  MISCELLANEOUS

     10.1  CONTINUATION OF SECURITY INTEREST. This is a continuing Agreement and
the grant of a security interest hereunder shall remain in full force and effect
and all the rights, powers and remedies of Lender hereunder shall continue to
exist until the Secured Obligations are paid in full as the same become due and
payable and until Lender has executed a written termination statement (which
Lender shall execute within a reasonable time after full payment of the Secured
Obligations hereunder), reassigning to Borrower, without recourse, the
Collateral and all rights conveyed hereby and returning possession of the
Collateral to Borrower. The rights, powers and remedies of Lender hereunder
shall be in addition to all rights, powers and remedies given by statute or rule
of law and are cumulative. The exercise of any one or more of the rights, powers
and remedies provided herein shall not be construed as a waiver of or election
of remedies with respect to any other rights, powers and remedies of Lender.

     10.2  SEVERABILITY. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under such law, such provision shall be ineffective only to the extent
and duration of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Agreement.

matter hereof and thereof, and supersede and replace in their entirety any prior
proposals, term sheets, letters, negotiations or other documents or agreements,
whether written or oral, with respect to the subject matter hereof or thereof
(including, without limitation, Lender's proposal letter dated November 20,
1998, all of which are merged herein and therein.  None of the terms of this
Agreement, the Note(s), any of the other Loan Documents or Warrant Agreement(s)
may be amended except by an instrument executed by each of the parties hereto.

     10.5  HEADINGS.  The various headings in this Agreement are inserted for
convenience only and shall not affect the meaning or interpretation of this
Agreement or any provisions hereof.

     10.6  NO WAIVER.  The powers conferred upon Lender by this Agreement are

upon Lender to exercise any 

                                       16
<PAGE>
 
such powers. No omission, or delay, by Lender at any time to enforce any right
or remedy reserved to it, or to require performance of any of the terms,
covenants or provisions hereof by Borrower at any time designated, shall be a
waiver of any such right or remedy to which Lender is entitled, nor shall it in
any way affect the right of Lender to enforce such provisions thereafter.

     10.7  SURVIVAL.  All agreements, representations and warranties contained
in this Agreement, the Note(s), the other Loan Documents and the Warrant
Agreement(s) or in any document delivered pursuant hereto or thereto shall be
for the benefit of Lender and shall survive the execution and delivery of this
Agreement and the expiration or other termination of this Agreement.

     10.8  SUCCESSOR AND ASSIGNS.  The provisions of this Agreement, the other
Loan Documents and the Warrant Agreement(s) shall inure to the benefit of and be
binding on Borrower and its permitted assigns (if any). Borrower shall not
assign its obligations under this Agreement, the Note(s), any of the other Loan
Documents or the Warrant Agreement(s), without Lender's express written consent,
and any such attempted assignment shall be void and of no effect. Lender may
assign, transfer, or endorse its rights hereunder and under the other Loan
Documents or Warrant Agreement(s) without prior notice to Borrower, and all of
such rights shall inure to the benefit of Lender's successors and assigns.

     10.9  FURTHER INDEMNIFICATION.  Borrower agrees to pay, and to save Lender
harmless from, any and all liabilities with respect to, or resulting from any
delay in paying, any and all excise, sales or other similar taxes which may be

connection with any of the transactions contemplated by this Agreement.

     10.10 GOVERNING LAW.  This Agreement, the Note(s), the other Loan Documents
and the Warrant Agreement(s) have been negotiated and delivered to Lender in the
State of Illinois, and shall not become effective until accepted by Lender in
the State of Illinois.  Payment to Lender by Borrower of the Secured Obligations
is due in the State of Illinois.  This Agreement, the Note(s), the other Loan
Documents and the Warrant Agreement(s) shall be governed by, and construed and
enforced in accordance with, the laws of the State of Illinois, excluding
conflict of laws principles that would cause the application of laws of any
other jurisdiction.

     10.11 CONSENT TO JURISDICTION AND VENUE.  All judicial proceedings arising
in or under or related to this Agreement, the Note(s), any of the other Loan
Documents or Warrant Agreement(s) may be brought in any state or federal court
of competent jurisdiction located in the State of Illinois. By execution and
delivery of this Agreement, each party hereto generally and unconditionally: (a)
consents to personal jurisdiction in Cook County, State of Illinois; (b) waives
any objection as to jurisdiction or venue in Cook County, State of Illinois; (c)
agrees not to assert any defense based on lack of jurisdiction or venue in the
aforesaid courts; and (d) irrevocably agrees to be bound by any judgment
rendered thereby in connection with this Agreement, the Note(s), the other Loan
Documents or Warrant Agreement(s). Service of process on any party hereto in any
action arising out of or relating to this agreement shall be effective if given
in accordance with the requirements for notice set forth in Section 10.3, above
and shall be deemed effective and received as set forth in Section 10.3, above.
Nothing herein shall affect the right to serve process in any other manner
permitted by law or shall limit the right of either party to bring proceedings
in the courts of any other jurisdiction.

                                       17
<PAGE>
 
     10.12 MUTUAL WAIVER OF JURY TRIAL.  Because disputes arising in connection
with complex financial transactions are most quickly and economically resolved
by an experienced and expert person and the parties wish applicable state and
federal laws to apply (rather than arbitration rules), the parties desire that
their disputes be resolved by a judge applying such applicable laws.  EACH OF
BORROWER AND LENDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY
OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR
ANY OTHER CLAIM (COLLECTIVELY, "CLAIMS") ASSERTED BY BORROWER AGAINST LENDER OR
ITS ASSIGNEE AND/OR BY LENDER OR ITS ASSIGNEE AGAINST BORROWER.  This waiver
extends to all such Claims, including, without limitation, Claims which involve
persons or entities other than Borrower and Lender; Claims which arise out of or
are in any way connected to the relationship between Borrower and Lender; and
any Claims for damages, breach of contract arising out of this Agreement, any
other Loan Document or any of the Excluded Agreements, specific performance, or
any equitable or legal relief of any kind.

     10.13 CONFIDENTIALITY.  Lender acknowledges that certain items of
Collateral, including, but not limited to trade secrets, source codes, customer
lists and certain other items of Intellectual Property, and any Financial
Statements provided pursuant to Section 6 hereof, constitute proprietary and
confidential information of the Borrower (the "Confidential Information").
Accordingly, Lender agrees that any Confidential Information it may obtain in
the course of acquiring, perfecting or foreclosing on the Collateral or
otherwise provided under this Agreement, provided such Confidential Information
is marked as confidential by Borrower at the time of disclosure, shall be
received in the strictest confidence and will not be disclosed to any other
person or entity in any manner whatsoever, in whole or in part, without the
prior written consent of the Borrower, unless and until Lender has acquired
indefeasible title thereto.

     10.14 COUNTERPARTS.  This Agreement and any amendments, waivers, consents
or supplements hereto may be executed in any number of counterparts, and by
different parties hereto in separate counterparts, each of which when so
delivered shall be deemed an original, but all of which counterparts shall
constitute but one and the same instrument.

IN WITNESS WHEREOF, the Borrower and the Lender have duly executed and delivered
this Agreement as of the day and year first above written.

                            SUBORDINATION AGREEMENT

                                        
     THIS SUBORDINATION AGREEMENT (this "Agreement") dated as of December
3,1998, is entered into by and between COMDISCO, INC., a Delaware corporation
("Subordinated Creditor"), and Vignette Corporation ("Borrower"), a Delaware
corporation, for the express benefit of Senior Creditor (as defined in Section
1, below).

                                   RECITALS

     Concurrently herewith, Subordinated Creditor is agreeing to advance to
Borrower a secured loan of money in the aggregate original principal amount of
Five Million Dollars ($5,000,000) as evidenced by a Subordinated Promissory Note
and a Subordinated Loan and Security Agreement, each dated as of December 3,
1998 (as the same may from time to time be amended, modified, supplemented,
extended, renewed, restated or replaced, the "Subordinated Note" and the
"Subordinated Loan Agreement," respectively), made by Borrower in favor of
Subordinated Creditor.  Borrower's obligations to Subordinated Creditor
evidenced by the Subordinated Note are secured by the personal property
collateral granted by Borrower to Subordinated Creditor pursuant to the
Subordinated Loan Agreement.

     Borrower has advised Subordinated Creditor that it contemplates entering
into a loan agreement (as the same may from time to time be amended, modified,
supplemented or restated, the "Senior Loan Agreement") with Senior Creditor,
pursuant to which Senior Creditor shall make available to Borrower, on a senior
secured basis, certain extensions of credit as described in the Senior Loan
Agreement.

     In contemplation of Borrower obtaining such senior secured financing and
the conditions expected to be imposed by Senior Creditor as conditions precedent
to making available to Borrower the proceeds of such financing, Subordinated
Creditor is entering into this Agreement with Borrower for the express benefit
of Senior Creditor, on the terms and subject to the conditions set forth below.

                                    AGREEMENT
                                        
     NOW, THEREFORE, in consideration of Borrower's and Subordinated Creditor's
entering into the Subordinated Loan Documents (as defined in Section 1, below),
Subordinated Creditor and Borrower hereby severally agree, each on behalf of
itself and for the benefit of Senior Creditor, as set forth below.

provided, that the Subordinated Loan Documents shall not include any of the

Subordinated Note requires prior written approval from Senior Creditor which

2.   SUBORDINATION

     (a)  On the terms and conditions set forth below, Subordinated Creditor's
right to payment and performance of the Subordinated Debt and all liens and
security interests securing the Subordinated Debt are hereby subordinated to
Senior Creditor's right to full payment and performance of the Senior Debt and
all liens and security interests securing the Senior Debt.  Subject to and
except as set forth in Section 3, below, Subordinated Creditor shall not ask,
demand, sue for, take or receive from Borrower, by setoff or in any other
manner, the whole or any part of any monies which may now or hereafter be owing
by Borrower to Subordinated Creditor, or be owing by any other person to
Subordinated Creditor under a guaranty or similar instrument, on account of the
Subordinated Debt, nor any collateral security for any of the foregoing,
including, without limitation, any personal property collateral granted to
Subordinated Creditor pursuant to the Subordinated Loan Agreement, unless and
until all Senior Debt shall have been paid in cash or otherwise provided for in
property or securities in the full amount of the allowed claim of the Senior
Debt and all commitments to extend credit under the Senior Loan Agreement shall
have been terminated (the temporary reduction of outstanding obligations,
liabilities and indebtedness of Borrower to Senior Creditor not being deemed to
constitute full payment or satisfaction thereof).  Nothing herein shall be
deemed to subordinate, waive or restrict the payment or performance of the
obligations arising under the Excluded Agreements or subordinate the priority of
any lien or interest in property securing or evidenced by the Excluded
Agreements.

     (b)  Subordinated Creditor expressly understands that Senior Creditor is
expected not to permit Subordinated Creditor to create, maintain or perfect any
lien on or in any property of Borrower, other than the security interest granted
in favor of Subordinated Creditor in certain of Borrower's personal property
under and as described in the Subordinated Loan Agreement and which liens and
security interests are junior to those securing the Senior Debt.  If,
notwithstanding the foregoing, any lien shall be created or shall arise
(including, without limitation, the security interests granted in favor of
Subordinated Creditor pursuant to the Subordinated Loan Agreement), whether by
operation of law or otherwise, and may from time to time exist in favor of
Subordinated Creditor in or on any property of Borrower to secure all or any
portion of the Subordinated Debt, then, regardless of the relative times of
attachment or perfection thereof or the order of filing of financing statements,
mortgages or other documents, any liens granted by Borrower in favor of Senior
Creditor to secure the Senior Debt shall in all respects be first and senior
liens, superior to any liens in favor of Subordinated Creditor securing the
Subordinated Debt, including, without limitation, the security interests granted
in favor of Subordinated Creditor pursuant to the Subordinated Loan Agreement.
In the event Subordinated Creditor has or obtains possession of any such
property or forecloses upon or enforces its lien upon any such property, whether
by judicial action or otherwise, then all such property shall be immediately
delivered in kind to Senior Creditor or, if not deliverable in kind, all cash or
non-cash proceeds and profits of such property shall be held in trust for the
benefit of Senior Creditor and paid over to Senior Creditor, without any
deduction or offset, unless and 

                                      -3-
<PAGE>
 
until all of the Senior Debt shall have been paid in cash or otherwise provided
for in property or securities in the full amount of the allowed claim of the
Senior Debt and all commitments to extend credit under the Loan Agreement shall
have been terminated.

     (c)  The subordination contained in this Agreement is intended to define
the rights and duties of Subordinated Creditor and Senior Creditor; it is not
intended that any third party (including any bankruptcy trustee, receiver, or
debtor-in-possession) shall benefit from it. If the effect of the subordination
contained in this Agreement would be to give any third party a priority status
to which that party would not otherwise be entitled, that provision shall, to
the extent necessary to avoid that priority, be given no effect and the rights
and priorities of Senior Creditor and Subordinated Creditor shall be determined
in accordance with applicable law and this Subordination Agreement.

3.   PERMITTED PAYMENTS; PAYMENT BLOCKAGE

     (a)  Notwithstanding anything to the contrary contained in Section 2,
above, but subject expressly to Section 3.b, below, Borrower shall be permitted
to make, and Subordinated Creditor shall be permitted to accept or receive the
following permitted payments ("Permitted Payments"): (i) scheduled repayments of
principal when due under the Subordinated Note(s) and Subordinated Loan
Agreement, (ii) scheduled payments of accrued interest when due under the
Subordinated Note(s) and Subordinated Loan Agreement, (iii) payments of
reimbursable expenses, costs and professional fees and expenses as and when due
under the Subordinated Note(s) and the other Subordinated Loan Documents, (iv)
cancellation of Subordinated Debt in consideration of the Exercise Price for
stock purchased by Subordinated Creditor under the Warrant Agreement, and (v)
other payments consented to in writing by Senior Creditor.

     (b)  Notwithstanding anything to the contrary contained in this Section 3
or elsewhere in this Agreement, if Senior Creditor delivers to Subordinated
Creditor written notice (a "Blockage Notice") which states that either:

          (i)    a specific default by Borrower involving the payment of Senior
     Debt (a "Payment Default") has occurred under the Senior Loan Documents and
     continues to exist after the giving of any required notice and the
     expiration of any applicable grace or cure period, or

          (ii)   a specific default by Borrower not involving the payment of
     Senior Debt (a "Non-Payment Default") has occurred under the Senior Loan
     Documents and continues to exist after the giving of any required notice
     and the expiration of any applicable grace or cure period, such notice to
     include all such defaults in existence at the time,

then from and after the date of delivery of any such Blockage Notice,
Subordinated Creditor shall not accept or receive any payment of any kind of or
on account of the Subordinated Debt (including any Permitted Payment), unless
and until the earlier of (A) the time such Payment Default or Non-Payment
Default shall have been cured by Borrower or waived in writing by Senior
Creditor, or (B) the expiration of the Blockage Period (as defined below) for
such Blockage Notice.

     As used herein, "Blockage Period" means a period of time beginning on the
date a Blockage Notice is delivered to Subordinated Creditor and terminating on
the earlier to occur of:

          (1)    120 days following such date; provided that if, prior to the
     expiration of such 120-day period, Senior Lender has commenced a judicial
     proceeding or non-

                                      -4-
<PAGE>
 
     judicial actions to collect or enforce the Senior Debt or the acceleration
     of the Senior Debt or the collateral for the Senior Debt, or a case or
     proceeding by or against Borrower is commenced under the federal Bankruptcy
     Code or any other insolvency law, then such period shall be extended during
     the continuation of such proceedings and actions until the payment in cash
     or other property or securities in the full amount of the allowed claim of
     the Senior Debt; or

          (2)    Senior Creditor's written consent to such termination.

Senior Creditor shall not issue more than two (2) Blockage Notice for Non-
Payment Defaults in any period of 365 consecutive days.  After the satisfaction
of the applicable conditions specified in (A) or (B) above, Subordinated
Creditor shall be entitled to receive all Permitted Payments.

4.   ENFORCEMENT RIGHTS

     Any rights of Subordinated Creditor to accelerate the maturity of the
Subordinated Debt, enforce any claim (including any default remedy) with respect
to the Subordinated Debt or the collateral for the Subordinated Debt, or
otherwise to take any action against Borrower or Borrower's property with
respect to the Subordinated Debt shall be subject to any Blockage Notice given
pursuant to Section 3.b hereof.

5.   ASSIGNMENT OF SUBORDINATED DEBT

     Subordinated Creditor hereby covenants to Senior Creditor that prior to the
termination of this Agreement in accordance with Section 10, below, the entire
Subordinated Debt created in favor of Subordinated Creditor shall continue to be
owing only to Subordinated Creditor, and any collateral security therefor
(including, without limitation, the collateral security granted to Subordinated
Creditor pursuant to the Subordinated Security Agreement) shall continue to be
held solely for the benefit of Subordinated Creditor, unless assigned pursuant
to an assignment made expressly subject to this Agreement.  The Subordinated
Note(s) shall be legended to expressly state that it is subject to this
Subordination Agreement.

6.   SENIOR CREDITOR'S PRIORITY

     In the event of any distribution, division, or application, partial or
complete, voluntary or involuntary, by operation of law or otherwise, of all or
any part of the property of Borrower or the proceeds thereof to the creditors of
Borrower, or the readjustment of the Senior Debt and the Subordinated Debt of
Borrower, whether by reason of liquidation, bankruptcy, arrangement,
receivership, assignment for the benefit of creditors or any other action or
proceeding involving the readjustment of all or any part of the Senior Debt or
the Subordinated Debt, or the application of the property of Borrower to the
payment or liquidation thereof, or upon the dissolution, liquidation,
reorganization, or other winding up of Borrower's business, or upon the sale of
all or any substantial part of Borrower's property (any of the foregoing being
hereinafter referred to as an "Insolvency Event"), then, and in any such event,
Senior Creditor shall be entitled to receive payment in cash or other property
or securities in the full amount of the allowed claim of the Senior Debt, before
Subordinated Creditor shall be entitled to receive any payment on account of the
Subordinated Debt, and to that end and in furtherance thereof:

          (a)    All payments and distributions of any kind or character,
     whether in cash, property, or securities, in respect of the Subordinated
     Debt to which Subordinated Creditor would be entitled if the Subordinated
     Debt were not subordinated pursuant to

                                      -5-
<PAGE>
 
     this Agreement, shall be paid to Senior Creditor and applied in payment of
     the Senior Debt.

          (b)    Subordinated Creditor shall file a claim or claims, on the form
     required in such proceedings, on or before thirty (30) days prior to the
     last date such claims or proofs of claim may be filed pursuant to law or
     the order of any court exercising jurisdiction over such proceeding.

          (c)    In the event that, notwithstanding the foregoing, any payment
     or distribution of any kind or character, whether in cash, properties or
     securities, shall be received by Subordinated Creditor on account of the
     Subordinated Debt before all of the Senior Debt has been paid, then such
     payment or distribution shall be received by Subordinated Creditor in trust
     for and shall be promptly paid over to Senior Creditor for application to
     the payments of amounts due on the Senior Debt until the Senior Debt shall
     have been paid in cash, property, or securities in the full amount of the
     allowed claim of the Senior Debt.

7.   GRANT OF AUTHORITY

     In the event of the occurrence of an Insolvency Event, and in order to
enable Senior Creditor to enforce its rights hereunder in any of the aforesaid
actions or proceedings, Senior Creditor is hereby irrevocably authorized and
empowered, in Senior Creditor's discretion, as follows:

          (a)    Senior Creditor is hereby irrevocably authorized and empowered
     (in its own name or in the name of Subordinated Creditor or otherwise), but
     shall have no obligation, (i) to demand, sue for, collect and receive every
     payment or distribution referred to in Section 6, above, and give
     acquittance therefor and (ii) (if Subordinated Creditor has failed to file
     claims or proofs of claim on or before thirty (30) days prior to the last
     date such claims or proofs of claim may be filed pursuant to law or the
     order of any court exercising jurisdiction over such proceeding) to file
     claims and proofs of claim, and (iii) to take such other action (including,
     without limitation, enforcing any lien securing payment of the Subordinated
     Debt) as it may deem necessary or advisable for the exercise or enforcement
     of any of the rights or interests of Senior Creditor hereunder.
     Subordinated Creditor shall duly and promptly take such action as Senior
     Creditor may reasonably request to execute and deliver to Senior Creditor
     such authorizations, endorsements, assignments, or other instruments as
     Senior Creditor may reasonably request in order to enable Senior Creditor
     to enforce any and all claims with respect to, and any liens securing
     payment of, the Subordinated Debt as such enforcement is contemplated
     herein.

          (b)    To the extent that payments or distributions on account of the
     Subordinated Debt are made in property or securities other than cash,
     Subordinated Creditor authorizes Senior Creditor to sell or dispose of such
     property or securities on such terms as are commercially reasonable in the
     situation in question.  Following full payment of the Senior Debt, Senior
     Creditor shall remit to Subordinated Creditor (with all necessary
     endorsements) to the extent of Subordinated Creditor's interest therein,
     all payments and distributions of cash, property, or securities paid to and
     held by Senior Creditor in excess of the allowed amount of the Senior Debt.

<PAGE>
 
     Should any payment, distribution, or security be received by Subordinated
Creditor upon or with respect to the Subordinated Debt (other than Permitted
Payments) prior to termination of this Agreement in accordance with Section 10,
below, Subordinated Creditor shall receive and hold the same in trust for the
benefit of Senior Creditor and shall forthwith deliver the same to Senior
Creditor in precisely the form received (except for the endorsement or
assignment of Subordinated Creditor where necessary), for application to the
Senior Debt, and, until so delivered, the same shall be held in trust by
Subordinated Creditor as the property of Senior Creditor.

9.   FURTHER ASSURANCES; COOPERATION

     Subject to Section 16.b hereof, Subordinated Creditor agrees to cooperate
with Senior Creditor and to take all actions that Senior Creditor may reasonably
require to enable Senior Creditor to realize the full benefits of this
Agreement.

10.  TERMINATION OF AGREEMENT

     This Agreement shall be effective upon the date set forth in Section 21
hereof.  After the effective date occurs, this Agreement shall remain in effect
and cannot be revoked or amended by Subordinated Creditor, except with the
written consent of Senior Creditor.  This Agreement shall terminate upon the
date which is 105 days following the date on which the Senior Debt shall have
been paid in cash or other property or securities in the full amount of the
allowed claim of the Senior Debt and all commitments to extend credit under the
Loan Agreement shall have been terminated.

11.  ADDITIONAL AGREEMENTS FOR SENIOR CREDITOR

     Senior Creditor may administer and manage its credit and other
relationships with Borrower in its own best interest, without notice to or
consent of Subordinated Creditor.  At any time and from time to time, Senior
Creditor may enter into any amendment or agreement with Borrower as Senior
Creditor may deem proper, extending the time of payment of or renewing or
otherwise altering the terms of all or any of the obligations constituting
Senior Debt or affecting the collateral security for, supporting or underlying
any or all of the Senior Debt, and may exchange, sell, release, surrender or
otherwise deal with any such collateral without in any way thereby impairing or
affecting this Agreement, and all such additional agreements and amendments
shall be "Senior Loan Documents" evidencing the Senior Debt; provided, that
neither this Section 11 nor any provision of such agreements shall affect the
limitations contained in the definitions of Senior Creditor or Senior Debt.

12.  SUBROGATION

     If cash or other property otherwise payable or deliverable to Subordinated
Creditor or on account of the Subordinated Debt shall have been applied pursuant
to this Agreement to the payment of the Senior Debt, and if the Senior Debt
shall have been paid in cash, property or securities in the full amount of the
allowed claim of Senior Debt, then Subordinated Creditor shall be subrogated to
any rights of Senior Creditor to receive further payments or distributions
applicable to the Senior Debt until the Subordinated Debt shall have been fully
paid.  No such payments or distributions received by Subordinated Creditor by
reason of such subrogation shall, as between Borrower and its creditors other
than Senior Creditor, on the one hand, and Subordinated Creditor, on the other
hand, be deemed to be a payment by Borrower on account of the Subordinated Debt
owed to Subordinated Creditor.

13.  SUBORDINATED CREDITOR'S WAIVERS AND COVENANTS

     (a)    Without limiting the generality of any other waiver made by
Subordinated Creditor in this Agreement, Subordinated Creditor hereby expressly
waives (i) reliance by Senior Creditor upon the subordination and other
agreements herein provided, and (ii) any claim that Subordinated Creditor may
now or hereafter have against Senior Creditor arising out of any and all actions
that Senior Creditor, in good faith, takes or omits to take (A) with respect to
the creation, perfection or continuation of liens in or on any collateral
security for the Senior Debt, (B) with respect to the foreclosure upon, sale,
release, or depreciation of, or failure to realize upon, any of the collateral
security for the Senior Debt, (C) with respect to the collection of any claim
for all or any part of the Senior Debt from any account debtor, guarantor or any
other third party and (D) with respect to the valuation, use, protection or
release of any collateral security for the Senior Debt.

     (b)    Without limiting the generality of any other covenant or agreement
made by Subordinated Creditor in this Agreement, Subordinated Creditor hereby
covenants and agrees that (i) Senior Creditor has not made any warranties or
representations with respect to the due execution, legality, validity,
completeness or enforceability of the Senior Loan Agreement or any of the other
Senior Loan Documents, or the collectibility of the Senior Debt; and (ii)
Subordinated Creditor will not interfere with or in any manner oppose a
disposition of any collateral security for the Senior Debt by Senior Creditor.

14.  REINSTATEMENT OF SENIOR DEBT

     To the extent that the Senior Creditor receives payments on, or proceeds of
any collateral security for the Senior Debt which are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, receiver or any other party under any bankruptcy law, state or
federal law, common law, or equitable cause, then, to the extent of such payment
or proceeds invalidated, declared to be fraudulent or preferential, set aside or
required to be repaid, the Senior Debt, or part thereof, intended to be
satisfied shall be revived and continue in full force and effect as if such
payments or proceeds had not been received by Senior Creditor.

15.  NO WAIVERS

     Senior Creditor shall not be prejudiced in its rights under this Agreement
by any act or failure to act of Borrower or Subordinated Creditor or any
noncompliance of Borrower or Subordinated Creditor with any agreement or
obligation, regardless of any knowledge thereof which Senior Creditor may have,
or with which Senior Creditor may be charged; and no action permitted hereunder
taken by Senior Creditor shall in any way affect or impair the rights of Senior
Creditor in the exercise of any other right or remedy or shall operate as a
waiver thereof, and no single or partial exercise by Senior Creditor of any
right or remedy shall preclude any other or further exercise thereof; nor shall
any modification or waiver of any of the provisions of this Agreement be binding
upon Senior Creditor, except as expressly set forth in a writing duly signed and
delivered by Senior Creditor.

16.  INFORMATION CONCERNING BORROWER; CREDIT ADMINISTRATION

     (a)    Subordinated Creditor hereby assumes responsibility for keeping
itself informed of the financial condition of Borrower, any and all endorsers
and any and all guarantors of the Senior Debt and of all other circumstances
bearing upon the risk of nonpayment of the Senior
<PAGE>
 
Debt or the Subordinated Debt that diligent inquiry would reveal, and
Subordinated Creditor hereby agrees that Senior Creditor shall have no duty to
advise Subordinated Creditor of information known to Senior Creditor regarding
such condition.

     (b)    Subject to Sections 2.b, 3, 4, 7, and 8 hereof, Subordinated
Creditor may (i) administer and manage its credit and other relationships with
Borrower in its own best interest, and (ii) amend or extend its agreements with
Borrower or enter into additional agreements with Borrower, all without the
consent of or notice to the Senior Creditor; provided that neither this Section
16.b nor any amendments or additional agreements referred to therein shall
impair or affect the subordination of Subordinated Debt or change the definition
of Subordinated Debt, Subordinated Creditor, Senior Debt or Senior Creditor.

18.  SEVERABILITY

     Wherever possible, each provision of this Agreement shall be interpreted in
such manner as to be effective and valid under applicable law, but if any
provision of this Agreement shall be prohibited by or invalid under applicable
law, such provision shall be ineffective to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Agreement.

19.  GOVERNING LAW

     This Agreement has been approved by Subordinated Creditor in the State of
California, and shall be governed by and interpreted in accordance with the laws
of the State of California without regard to principles of conflict of laws that
would cause the application of laws of any other jurisdiction.

20.  ASSIGNMENT

     This Agreement shall be binding upon Subordinated Creditor, Borrower and
their respective successors and assigns, and shall inure to the benefit of and
be enforceable by Senior Creditor and its successors and assigns.

21.  EFFECTIVENESS OF AGREEMENT

     This Agreement shall be effective upon the occurrence of both of the
following events:  (a) the execution of this Agreement by Borrower and its
acceptance in Rosemont, Illinois by Subordinated Creditor, and (b) the delivery
by Borrower and Senior Creditor to Subordinated Creditor of written notice (the
"Notice of Senior Loan") in the form attached hereto as Exhibit A, that Borrower
has entered into a Senior Loan Agreement with Senior Creditor for Senior Debt,
which notice shall identify Senior Creditor and state the address to which
notices to Senior Creditor are to be sent.  Borrower agrees to furnish
Subordinated Creditor with a copy of the Senior Loan Agreement and such other
Senior Loan Documents as Subordinated Creditor shall reasonably request;
provided, however, that any delay or failure by Borrower to furnish such copies
shall not limit or impair the effectiveness of this Agreement.

22.  MUTUAL WAIVER OF JURY TRIAL

     Because disputes arising in connection with complex financial transactions
are most quickly and economically resolved by an experienced and expert person
and the parties wish applicable state and federal laws to apply (rather than
arbitration rules), the parties desire that their disputes be resolved by a
judge applying such applicable laws.  EACH OF BORROWER, SUBORDINATED CREDITOR,
AND SENIOR CREDITOR SPECIFICALLY WAIVE EACH PARTY'S RIGHT TO TRIAL BY JURY OF
ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY
OTHER CLAIM (COLLECTIVELY, "CLAIMS") ASSERTED BY BORROWER, SUBORDINATED
CREDITOR, OR SENIOR CREDITOR AGAINST THE OTHER PARTY OR PARTIES TO THIS
AGREEMENT.  This Waiver extends to all such claims, including, without
limitation, claims which involve persons or entities other than Borrower,
Subordinated Creditor, and Senior Creditor; claims which arise out of or are in
any way connected to the relationships between or among Borrower, Subordinated
Creditor, and Senior Creditor; and any claims for damages, breach of contract,
specific performance, or any equitable or legal relief of any kind.

23.  COUNTERPARTS

     This Agreement and any amendments, waivers, consents or supplements hereto
may be executed in any number of counterparts, and by different parties hereto
in separate counterparts, each of which when so executed and delivered shall be
deemed an original, but all of which counterparts together shall constitute but
one and the same instrument.

     IN WITNESS WHEREOF, this Subordination Agreement has been executed as of
the date first above written.

                               WARRANT AGREEMENT

             TO PURCHASE SHARES OF THE SERIES H PREFERRED STOCK OF

                             VIGNETTE CORPORATION

              DATED AS OF DECEMBER 3, 1998 (THE "EFFECTIVE DATE")

                                        

     WHEREAS, Vignette Corporation, a Delaware corporation (the "Company") has
entered into a Subordinated Loan and Security Agreement dated as of December 3,
1998, and related Subordinated Promissory Note(s) (collectively, the "Loans")
with Comdisco, Inc., a Delaware corporation (the "Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Loans, the right to purchase shares of its Series H Preferred Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Loans and in consideration of mutual covenants and agreements
contained herein, the Company and Warrantholder agree as follows:

1.   GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

     The Company hereby grants to the Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth, to
subscribe to and purchase, from the Company, 42,865 fully paid and non-
assessable shares of the Company's Series H Preferred Stock ("Preferred Stock")
at a purchase price of $16.33 per share (the "Exercise Price").  The number and
purchase price of such shares are subject to adjustment as provided in Section 8
hereof.

2.   TERM OF THE WARRANT AGREEMENT.

     Except as otherwise provided for herein, the term of this Warrant Agreement
and the right to purchase Preferred Stock as granted herein shall commence on
the Effective Date and shall be exercisable for a period of (i) seven (7) years
or (ii) three (3) years from the effective date of the Company's initial public
offering, whichever is shorter.

3.   EXERCISE OF THE PURCHASE RIGHTS.

     The purchase rights set forth in this Warrant Agreement are exercisable by
the Warrantholder, in whole or in part, at any time, or from time to time, prior
to the expiration of the term set forth in Section 2 above, by tendering to the
Company at its principal office a notice of exercise in the form attached hereto
as Exhibit I (the "Notice of Exercise"), duly completed and executed.  Promptly
upon receipt of the Notice of Exercise and the payment of the purchase price in
accordance with the terms set forth below, and in no event later than twenty-one
(21) days thereafter, the Company shall issue to the Warrantholder a certificate
for the number of shares of Preferred Stock purchased and shall execute the
acknowledgment of exercise in the form attached hereto as Exhibit II (the
"Acknowledgment of Exercise") indicating the number of shares which remain
subject to future purchases, if any.

     The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, or (ii) by surrender of Warrants ("Net Issuance") as
determined below.  If the Warrantholder elects the Net Issuance method, the
Company will issue Preferred Stock in accordance with the following formula:

             X = Y(A-B)
                 ------
                   A

                                      -1-
<PAGE>
 
     Where:  X =    the number of shares of Preferred Stock to be issued to the
                    Warrantholder.

             Y =    the number of shares of Preferred Stock requested to be
                    exercised under this Warrant Agreement.

             A =    the fair market value of one (1) share of Preferred Stock.

             B =    the Exercise Price.

     For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each share of Preferred Stock:

             (i)    if the exercise is in connection with an initial public
     offering of the Company's Common Stock, and if the Company's Registration
     Statement relating to such public offering has been declared effective by
     the SEC, then the fair market value per share shall be the product of (x)
     the initial "Price to Public" specified in the final prospectus with
     respect to the offering and (y) the number of shares of Common Stock into
     which each share of Preferred Stock is convertible at the time of such
     exercise;

             (ii)   if this Warrant is exercised after, and not in connection
     with the Company's initial public offering, and:

                    (a)  if traded on a securities exchange, the fair market
             value shall be deemed to be the product of (x) the average of the
             closing prices over a twenty-one (21) day period ending three days
             before the day the current fair market value of the securities is
             being determined and (y) the number of shares of Common Stock into
             which each share of Preferred Stock is convertible at the time of
             such exercise; or

                    (b)  if actively traded over-the-counter, the fair market
             value shall be deemed to be the product of (x) the average of the
             closing bid and asked prices quoted on the NASDAQ system (or
             similar system) over the twenty-one (21) day period ending three
             days before the day the current fair market value of the securities
             is being determined and (y) the number of shares of Common Stock
             into which each share of Preferred Stock is convertible at the time
             of such exercise;

             (iii)  if at any time the Common Stock is not listed on any
     securities exchange or quoted in the NASDAQ System or the over-the-counter
     market, the current fair market value of Preferred Stock shall be the
     product of (x) the highest price per share which the Company could obtain
     from a willing buyer (not a current employee or director) for shares of
     Common Stock sold by the Company, from authorized but unissued shares, as
     determined in good faith by its Board of Directors and (y) the number of
     shares of Common Stock into which each share of Preferred Stock is
     convertible at the time of such exercise, unless the Company shall become
     subject to a merger, acquisition or other consolidation pursuant to which
     the Company is not the surviving party, in which case the fair market value
     of Preferred Stock shall be deemed to be the value received by the holders
     of the Company's Preferred Stock on a common equivalent basis pursuant to
     such merger or acquisition.

     Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number of
shares purchasable hereunder. All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.   RESERVATION OF SHARES.

     (a)     Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b)     Registration or Listing. If any shares of Preferred Stock required
to be reserved hereunder require registration with or approval of any
governmental authority under any Federal or State law (other than any
registration under the Securities Act of 1933, as amended ("1933 Act"), as then
in effect, or any similar Federal statute then enforced, or any state securities
law, required by reason of any transfer involved in such conversion), or listing
on any domestic securities exchange, before such shares may be issued upon
conversion, the Company will, at its expense and as expeditiously as possible,
use its best efforts to cause such shares to be duly registered, listed or
approved for listing on such domestic securities exchange, as the case may be.

5.   NO FRACTIONAL SHARES OR SCRIP.

     No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrant, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the Exercise
Price then in effect.

6.   NO RIGHTS AS SHAREHOLDER.

     This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrant.

7.   WARRANTHOLDER REGISTRY.

     The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.   ADJUSTMENT RIGHTS.

     The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

     (a)     Merger and Sale of Assets.  If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation whether or not the Company is the surviving corporation, or the sale
of all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of the Warrant, the number of
shares of preferred stock or other securities of the successor corporation
resulting from such Merger Event, equivalent in value to that which would have
been issuable if Warrantholder had exercised this Warrant immediately prior to
the Merger Event.  In any such case, appropriate adjustment (as determined in
good faith by the Company's Board of Directors) shall be made in the application
of the provisions of this Warrant Agreement with respect to the rights and
interest of the Warrantholder after the Merger Event to the end that the
provisions of this Warrant Agreement (including adjustments of the Exercise
Price and number of shares of Preferred Stock purchasable) shall be applicable
to the greatest extent possible.

     (b)     Reclassification of Shares.  If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of any
other class or classes, this Warrant Agreement shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable
as the result of such change with respect to the securities which were subject
to the purchase rights under this Warrant Agreement immediately prior to such
combination, reclassification, exchange, subdivision or other change.

     (c)     Subdivision or Combination of Shares.  If the Company at any time
shall combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d)     Stock Dividends.  If the Company at any time shall pay a dividend
payable in, or make any other distribution (except any distribution specifically
provided for in the foregoing subsections (a) or (b)) of the Company's stock,
then the Exercise Price shall be adjusted, from and after the record date of
such dividend or distribution, to that price determined by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction (i)
the numerator of which shall be the total number of all shares of the Company's
stock outstanding immediately prior to such dividend or distribution, and (ii)
the denominator of which shall be the total number of all shares of the
Company's stock outstanding immediately after such dividend or distribution.
The Warrantholder shall thereafter be entitled to purchase, at the Exercise
Price resulting from such adjustment, the number of shares of Preferred Stock
(calculated to the nearest whole share) obtained by multiplying the Exercise
Price in effect immediately prior to such adjustment by the number of shares of
Preferred Stock issuable upon the exercise hereof immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

     (e)     Right to Purchase Additional Stock.  If the Company has not paid
any Subordinated Promissory Note(s) entered into pursuant to the Loan(s) in its
entirety by the Maturity Date (as defined in the applicable Subordinated
Promissory Note(s)), then for each additional month, or portion thereof,
thereafter that the outstanding


                                      -3-
<PAGE>
 
principal is not paid, Warrantholder shall have the right to purchase from the
Company, at the Exercise Price (adjusted as set forth herein), an additional
number of shares of Preferred Stock which number shall be determined by (i)
multiplying the outstanding principal amount which due but unpaid by 1% and (ii)
dividing the product thereof by the Exercise Price.

     (f)     Antidilution Rights.  Additional antidilution rights applicable to
the Preferred Stock purchasable hereunder are as set forth in the Company's
Certificate of Incorporation, as amended through the Effective Date, a true and
complete copy of which is attached hereto as Exhibit __ (the "Charter"). The
Company shall promptly provide the Warrantholder with any restatement,
amendment, modification or waiver of the Charter. The Company shall provide
Warrantholder with prior written notice of any issuance of its stock or other
equity security to occur after the Effective Date of this Warrant, which notice
shall include (a) the price at which such stock or security is to be sold, (b)
the number of shares to be issued, and (c) such other information as necessary
for Warrantholder to determine if a dilutive event has occurred.

     (g)     Notice of Adjustments.  If: (i) the Company shall declare any
dividend or distribution upon its stock, whether in cash, property, stock or
other securities; (ii) the Company shall offer for subscription prorata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock of any class or other rights; (iii) there shall be any Merger
Event; (iv) there shall be an initial public offering; or (v) there shall be any
voluntary dissolution, liquidation or winding up of the Company; then, in
connection with each such event, the Company shall send to the Warrantholder:
(A) at least twenty (20) days' prior written notice of the date on which the
books of the Company shall close or a record shall be taken for such dividend,
distribution, subscription rights (specifying the date on which the holders of
Preferred Stock shall be entitled thereto) or for determining rights to vote in
respect of such Merger Event, dissolution, liquidation or winding up; (B) in the
case of any such Merger Event, dissolution, liquidation or winding up, at least
twenty (20) days' prior written notice of the date when the same shall take
place (and specifying the date on which the holders of Preferred Stock shall be
entitled to exchange their Preferred Stock for securities or other property
deliverable upon such Merger Event, dissolution, liquidation or winding up); and
(C) in the case of a public offering, the Company shall give the Warrantholder
at least twenty (20) days written notice prior to the effective date thereof.

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and (v)
the number of shares subject to purchase hereunder after giving effect to such
adjustment, and shall be given by first class mail, postage prepaid, addressed
to the Warrantholder, at the address as shown on the books of the Company.

     (h)     Timely Notice.  Failure to timely provide such notice required by
subsection (g) above shall entitle Warrantholder to retain the benefit of the
applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder. The notice period shall begin
on the date Warrantholder actually receives a written notice containing all the
information specified above.

10.  REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

     This Warrant Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder:

     (a)     Investment Purpose.  The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b)     Private Issue.  The Warrantholder understands (i) that the
Preferred Stock issuable upon exercise of this Warrant is not registered under
the 1933 Act or qualified under applicable state securities laws on the ground
that the issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c)     Disposition of Warrantholder's Rights.  In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available.  Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required.  Whenever
the restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

     (d)     Financial Risk.  The Warrantholder has such knowledge and
experience in financial and business matters as to be capable of evaluating the
merits and risks of its investment, and has the ability to bear the economic
risks of its investment.

     (e)     Risk of No Registration.  The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "1934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act", or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the right to purchase, it may be
required to hold such securities for an indefinite period.  The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     (f)     Accredited Investor.   Warrantholder is an "accredited investor"
within the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.

11.  TRANSFERS.

     Subject to the terms and conditions contained in Section 10 hereof, this
Warrant Agreement and all rights hereunder are transferable in whole or in part
by the Warrantholder and any successor transferee, provided, however, in no
event shall the number of transfers of the rights and interests in all of the
Warrants exceed three (3)

                   M A S T E R  L E A S E  A G R E E M E N T

MASTER LEASE AGREEMENT (the "Master Lease") dated December 3, 1998 by and
between COMDISCO, INC. ("Lessor") and VIGNETTE CORPORATION ("Lessee").

IN CONSIDERATION of the mutual agreements described below, the parties agree as
follows (all capitalized terms are defined in Section 14.18):

1. PROPERTY LEASED.

Lessor leases to Lessee all of the Equipment described on each Summary Equipment
Schedule. In the event of a conflict, the terms of the applicable Schedule
prevail over this Master Lease.

2. TERM.

On the Commencement Date, Lessee will be deemed to accept the Equipment, will be
bound to its rental obligations for each item of Equipment and the term of a
Summary Equipment Schedule will begin and continue through the Initial Term and
thereafter until terminated by either party upon prior written notice received
during the Notice Period. No termination may be effective prior to the
expiration of the Initial Term.

3. RENT AND PAYMENT.

Rent is due and payable in advance on the first day of each Rent Interval at the
address specified in Lessor's invoice. Interim Rent is due and payable when
invoiced. If any payment is not made when due, Lessee will pay a Late Charge on
the overdue amount. Upon Lessee's execution of each Schedule, Lessee will pay
Lessor the Advance specified on the Schedule. The Advance will be credited
towards the final Rent payment if Lessee is not then in default. No interest
will be paid on the Advance.

4. SELECTION; WARRANTY AND DISCLAIMER OF WARRANTIES.

4.1 SELECTION. Lessee acknowledges that it has selected the Equipment and
disclaims any reliance upon statements made by the Lessor, other than as set
forth in the Schedule.

4.2 WARRANTY AND DISCLAIMER OF WARRANTIES. Lessor warrants to Lessee that, so
long as Lessee is not in default, Lessor will not disturb Lessee's quiet and
peaceful possession, and unrestricted use of the Equipment. To the extent
permitted by the manufacturer, Lessor assigns to Lessee during the term of the
Summary Equipment Schedule any manufacturer's warranties for the Equipment.
LESSOR MAKES NO OTHER WARRANTY, EXPRESS OR IMPLIED AS TO ANY MATTER WHATSOEVER,
INCLUDING, WITHOUT LIMITATION, THE MERCHANTABILITY OF THE EQUIPMENT OR ITS
FITNESS FOR A PARTICULAR PURPOSE. Lessor is not responsible for any liability,
claim, loss, damage or expense of any kind (including strict liability in tort)
caused by the Equipment except for any loss or damage caused by the willful
misconduct or negligent acts of Lessor. In no event is Lessor responsible for
special, incidental or consequential damages.

5. TITLE; RELOCATION OR SUBLEASE; AND ASSIGNMENT.

5.1 TITLE. Lessee holds the Equipment subject and subordinate to the rights of
the Owner, Lessor, any Assignee and any Secured Party. Lessee authorizes Lessor,
as Lessee's agent, and at Lessor's expense, to prepare, execute and file in
Lessee's name precautionary Uniform Commercial Code financing statements showing
the interest of the Owner, Lessor, and any Assignee or Secured Party in the
Equipment and to insert serial numbers in Summary Equipment Schedules as
appropriate. Lessee will, at its expense, keep the Equipment free and clear from
any liens or encumbrances of any kind (except any caused by Lessor) and will
indemnify and hold the Owner, Lessor, any Assignee and Secured Party harmless
from and against any loss caused by Lessee's failure to do so, except where such
is caused by Lessor.

5.2 RELOCATION OR SUBLEASE. Upon prior written notice, Lessee may relocate
Equipment to any location within the continental United States provided (i) the
Equipment will not be used by an entity exempt from federal income tax, and (ii)
all additional costs (including any administrative fees, additional taxes and
insurance coverage) are reconciled and promptly paid by Lessee.

Lessee may sublease the Equipment upon the reasonable consent of the Lessor and
the Secured Party. Such consent to sublease will be granted if: (i) Lessee meets
the relocation requirements set out above, (ii) the sublease is expressly
subject and subordinate to the terms of the Schedule, (iii) Lessee assigns its
rights in the sublease to Lessor and the Secured Party as additional collateral
and security, (iv) Lessee's obligation to maintain and insure the Equipment is
not altered, (v) all financing statements required to continue the Secured
Party's prior perfected security interest are filed, and (vi) Lessee executes
sublease documents acceptable to Lessor.

No relocation or sublease will relieve Lessee from any of its obligations under
this Master Lease and the relevant Schedule.

5.3 ASSIGNMENT BY LESSOR. The terms and conditions of each Schedule have been
fixed by Lessor in order to permit Lessor to sell and/or assign or transfer its
interest or grant a security interest in each Schedule and/or the Equipment to a
Secured Party or Assignee. In that event, the term Lessor will mean the Assignee
and any Secured Party. However, any assignment, sale, or other transfer by
Lessor will not relieve Lessor of its obligations to Lessee and will not
materially change Lessee's duties or materially increase the burdens or risks
imposed on Lessee. The Lessee consents to and will acknowledge such assignments
in a written notice given to Lessee. Lessee also agrees that:

(a)        The Secured Party will be entitled to exercise all of Lessor's
rights, but will not be obligated to perform any of the obligations of Lessor.
The Secured Party will not disturb Lessee's quiet and peaceful possession and
unrestricted use of the Equipment so long as Lessee is not in default and the
Secured Party continues to receive all Rent payable under the Schedule; and

(b)        Lessee will pay all Rent and all other amounts payable to the Secured
Party, despite any defense or claim which it has against Lessor. Lessee reserves
its right to have recourse directly against Lessor for any defense or claim;

(c)        Subject to and without impairment of Lessee's leasehold rights in the
Equipment, Lessee holds the Equipment for the Secured Party to the extent of the
Secured Party's rights in that Equipment.

6. NET LEASE; TAXES AND FEES.

6.1 NET LEASE. Each Summary Equipment Schedule constitutes a net lease. Lessee's
obligation to pay Rent and all other amounts due hereunder is absolute and
unconditional and is not subject to any abatement, reduction, set-off, defense,
counterclaim, interruption, deferment or recoupment for any reason whatsoever.

6.2 TAXES AND FEES. Lessee will pay when due or reimburse Lessor for all taxes,
fees or any other charges (together with any related interest or penalties not
arising from the negligence of Lessor) accrued for or arising during the term of
each Summary Equipment Schedule against Lessor, Lessee or the Equipment by any
governmental authority (except only Federal, state, local and franchise taxes on
the capital or the net income of Lessor). Lessor will file all personal property
tax returns for the Equipment and pay all such property taxes due. Lessee will
reimburse Lessor for property taxes within thirty (30) days of receipt of an
invoice.

7. CARE, USE AND MAINTENANCE; INSPECTION BY LESSOR.

7.1 CARE, USE AND MAINTENANCE. Lessee will maintain the Equipment in good
operating order and appearance, protect the Equipment from deterioration, other
than normal wear and tear, and will not use the Equipment for any purpose other
than that for which it was designed. If commercially available and considered
common business practice for each item of Equipment, Lessee will maintain in
force a standard maintenance contract with the manufacturer of the Equipment, or
another party acceptable to Lessor, and will provide Lessor with a complete copy
of that contract. If Lessee has the Equipment maintained by a party other than
the manufacturer or self maintains, Lessee agrees to pay any costs necessary for
the manufacturer to bring the Equipment to then current release, revision and
engineering change levels, and to re-certify the Equipment as eligible for
manufacturer's maintenance at the expiration of the lease term, provided re-
certification is available and is required by Lessor. The lease term will
continue upon the same terms and conditions until recertification has been
obtained.
 
7.2 INSPECTION BY LESSOR. Upon reasonable advance notice, Lessee, during
reasonable business hours and subject to Lessee's security requirements, will
make the Equipment and its related log and maintenance records available to
Lessor for inspection.

8. REPRESENTATIONS AND WARRANTIES OF LESSEE. Lessee hereby represents, warrants
and covenants that with respect to the Master Lease and each Schedule executed
hereunder:

(a)        The Lessee is a corporation duly organized and validly existing in
good standing under the laws of the jurisdiction of its incorporation, is duly
qualified to do business in each jurisdiction (including the jurisdiction where
the Equipment is, or is to be, located) where its ownership or lease of property
or the conduct of its business requires such qualification, except for where
such lack of qualification would not have a material adverse effect on the
Company's business; and has full corporate power and authority to hold property
under the Master Lease and each Schedule and to enter into and perform its
obligations under the Master Lease and each Schedule.

(b)        The execution and delivery by the Lessee of the Master Lease and each
Schedule and its performance thereunder have been duly authorized by all
necessary corporate action on the part of the Lessee, and the Master Lease and
each Schedule are not inconsistent with the Lessee's Articles of Incorporation
or Bylaws, do not contravene any law or governmental rule, regulation or order
applicable to it, do not and will not contravene any provision of, or constitute
a default under, any indenture, mortgage, contract or other instrument to which
it is a party or by which it is bound, and the Master Lease and each Schedule
constitute legal, valid and binding

                                      -1-
<PAGE>
 
agreements of the Lessee, enforceable in accordance with their terms, subject to
the effect of applicable bankruptcy and other similar laws affecting the rights
of creditors generally and rules of law concerning equitable remedies.

(c)        There are no actions, suits, proceedings or patent claims pending or,
to the knowledge of the Lessee, threatened against or affecting the Lessee in
any court or before any governmental commission, board or authority which, if
adversely determined, will have a material adverse effect on the ability of the
Lessee to perform its obligations under the Master Lease and each Schedule.

(d)        The Equipment is personal property and when subjected to use by the
Lessee will not be or become fixtures under applicable law.

(e)        The Lessee has no material liabilities or obligations, absolute or
contingent (individually or in the aggregate), except the liabilities and
obligations of the Lessee as set forth in the Financial Statements and
liabilities and obligations which have occurred in the ordinary course of
business, and which have not been, in any case or in the aggregate, materially
adverse to Lessee's ongoing business.

(f)        To the best of the Lessee's knowledge, the Lessee owns, possesses,
has access to, or can become licensed on reasonable terms under all patents,
patent applications, trademarks, trade names, inventions, franchises, licenses,
permits, computer software and copyrights necessary for the operations of its
business as now conducted, with no known infringement of, or conflict with, the
rights of others.

(g)        All material contracts, agreements and instruments to which the
Lessee is a party are in full force and effect in all material respects, and are
valid, binding and enforceable by the Lessee in accordance with their respective
terms, subject to the effect of applicable bankruptcy and other similar laws
affecting the rights of creditors generally, and rules of law concerning
equitable remedies.

9.   DELIVERY AND RETURN OF EQUIPMENT.

Lessee hereby assumes the full expense of transportation and in-transit
insurance to Lessee's premises and installation thereat of the Equipment. Upon
termination (by expiration or otherwise) of each Summary Equipment Schedule,
Lessee shall, pursuant to Lessor's instructions and at Lessee's full expense
(including, without limitation, expenses of transportation and in-transit
insurance), return the Equipment to Lessor in the same operating order, repair,
condition and appearance as when received, less normal depreciation and wear and
tear. Lessee shall return the Equipment to Lessor at 6111 North River Road,
Rosemont, Illinois 60018 or at such other address within the continental United
States as directed by Lessor, provided, however, that Lessee's expense shall be
limited to the cost of returning the Equipment to Lessor's address as set forth
herein. During the period subsequent to receipt of a notice under Section 2,
Lessor may demonstrate the Equipment's operation in place and Lessee will supply
any of its personnel as may reasonably be required to assist in the
demonstrations.

10. LABELING.

Upon request, Lessee will mark the Equipment indicating Lessor's interest with
labels provided by Lessor. Lessee will keep all Equipment free from any other
marking or labeling which might be interpreted as a claim of ownership.

11. INDEMNITY.

With regard to bodily injury and property damage liability only, Lessee will
indemnify and hold Lessor, any Assignee and any Secured Party harmless from and
against any and all claims, costs, expenses, damages and liabilities, including
reasonable attorneys' fees, arising out of the ownership (for strict liability
in tort only), selection, possession, leasing, operation, control, use,
maintenance, delivery, return or other disposition of the Equipment during the
term of this Master Lease or until Lessee's obligations under the Master Lease
terminate. However, Lessee is not responsible to a party indemnified hereunder
for any claims, costs, expenses, damages and liabilities occasioned by the
negligent acts of such indemnified party. Lessee agrees to carry bodily injury
and property damage liability insurance during the term of the Master Lease in
amounts and against risks customarily insured against by the Lessee on equipment
owned by it. Any amounts received by Lessor under that insurance will be
credited against Lessee's obligations under this Section.

12. RISK OF LOSS.

Effective upon delivery and until the Equipment is returned, Lessee relieves
Lessor of responsibility for all risks of physical damage to or loss or
destruction of the Equipment. Lessee will carry casualty insurance for each item
of Equipment in an amount not less than the Casualty Value. All policies for
such insurance will name the Lessor and any Secured Party as additional insured
and as loss payee, and will provide for at least thirty (30) days prior written
notice to the Lessor of cancellation or expiration, and will insure Lessor's
interests regardless of any breach or violation by Lessee of any representation,
warranty or condition contained in such policies and will be primary without
right of contribution from any insurance effected by Lessor. Upon the execution
of any Schedule, the Lessee will furnish appropriate evidence of such insurance
acceptable to Lessor.

Lessee will promptly repair any damaged item of Equipment unless such Equipment
has suffered a Casualty Loss. Within fifteen (15) days of a Casualty Loss,
Lessee will provide written notice of that loss to Lessor and Lessee will, at
Lessee's option, either (a) replace the item of Equipment with Like Equipment
and marketable title to the Like Equipment will automatically vest in Lessor or
(b) pay the Casualty Value and after that payment and the payment of all other
amounts due and owing with respect to that item of Equipment, Lessee's
obligation to pay further Rent for the item of Equipment will cease.

13. DEFAULT, REMEDIES AND MITIGATION.

13.1 DEFAULT. The occurrence of any one or more of the following Events of
Default constitutes a default under a Summary Equipment Schedule:

(a)        Lessee's failure to pay Rent or other amounts payable by Lessee when
due if that failure continues for five (5) business days after written notice;
or

(b)        Lessee's failure to perform any other term or condition of the
Schedule or the material inaccuracy of any representation or warranty made by
the Lessee in the Schedule or in any document or certificate furnished to the
Lessor hereunder if that failure or inaccuracy continues for ten (10) business
days after written notice; or

(c)        An assignment by Lessee for the benefit of its creditors, the failure
by Lessee to pay its debts when due, the insolvency of Lessee, the filing by
Lessee or the filing against Lessee of any petition under any bankruptcy or
insolvency law or for the appointment of a trustee or other officer with similar
powers, the adjudication of Lessee as insolvent, the liquidation of Lessee, or
the taking of any action for the purpose of the foregoing; or

(d)        The occurrence of an Event of Default under any Schedule, Summary
Equipment Schedule or other agreement between Lessee and Lessor or its Assignee
or Secured Party.

13.2 REMEDIES. Upon the occurrence of any of the above Events of Default,
Lessor, at its option, may:

(a)        enforce Lessee's performance of the provisions of the applicable
Schedule by appropriate court action in law or in equity;

(b)        recover from Lessee any damages and or expenses, including Default
Costs;

(c)        with notice and demand, recover all sums due and accelerate and
recover the present value of the remaining payment stream of all Rent due under
the defaulted Schedule (discounted at the same rate of interest at which such
defaulted Schedule was discounted with a Secured Party plus any prepayment fees
charged to Lessor by the Secured Party or, if there is no Secured Party, then
discounted at 6%) together with all Rent and other amounts currently due as
liquidated damages and not as a penalty;

(d)        with notice and process of law and in compliance with Lessee's
security requirements, Lessor may enter on Lessee's premises to remove and
repossess the Equipment without being liable to Lessee for damages due to the
repossession, except those resulting from Lessor's, its assignees', agents' or
representatives' negligence; and

(e)        pursue any other remedy permitted by law or equity.

The above remedies, in Lessor's discretion and to the extent permitted by law,
are cumulative and may be exercised successively or concurrently.

13.3 MITIGATION. Upon return of the Equipment pursuant to the terms of Section
13.2, Lessor will use its best efforts in accordance with its normal business
procedures (and without obligation to give any priority to such Equipment) to
mitigate Lessor's damages as described below. EXCEPT AS SET FORTH IN THIS
SECTION, LESSEE HEREBY WAIVES ANY RIGHTS NOW OR HEREAFTER CONFERRED BY STATUTE
OR OTHERWISE WHICH MAY REQUIRE LESSOR TO MITIGATE ITS DAMAGES OR MODIFY ANY OF
LESSOR'S RIGHTS OR REMEDIES STATED HEREIN. Lessor may sell, lease or otherwise
dispose of all or any part of the Equipment at a public or private sale for cash
or credit with the privilege of purchasing the Equipment. The proceeds from any
sale, lease or other disposition of the Equipment are defined as either:

(a)        if sold or otherwise disposed of, the cash proceeds less the Fair
Market Value of the Equipment at the expiration of the Initial Term less the
Default Costs; or

(b)        if leased, the present value (discounted at three percent (3%) over
the U.S. Treasury Notes of comparable maturity to the term of the re-lease) of
the rentals for a term not to exceed the Initial Term, less the Default Costs.

Any proceeds will be applied against liquidated damages and any other sums due
to Lessor from Lessee. However, Lessee is liable to Lessor for, and Lessor may
recover, the amount by which the proceeds are less than the liquidated damages
and other sums due to Lessor from Lessee.

14. ADDITIONAL PROVISIONS.

                                      -2-
<PAGE>
 
14.1 BOARD ATTENDANCE. Upon invitation of Lessee, one representative of Lessor
will have the right to attend Lessee's corporate Board of Directors meetings and
Lessee will give Lessor reasonable notice in advance of any special Board of
Directors meeting, which notice will provide an agenda of the subject matter to
be discussed at such board meeting. Lessee will provide Lessor with a certified
copy of the minutes of each Board of Directors meeting within thirty (30) days
following the date of such meeting held during the term of this Master Lease.

14.2 FINANCIAL STATEMENTS. As soon as practicable at the end of each month (and
in any event within thirty (30) days), Lessee will provide to Lessor the same
information which Lessee provides to its Board of Directors, but which will
include not less than a monthly income statement, balance sheet and statement of
cash flows prepared in accordance with generally accepted accounting principles,
consistently applied (the "Financial Statements"). As soon as practicable at the
end of each fiscal year, Lessee will provide to Lessor audited Financial
Statements setting forth in comparative form the corresponding figures for the
fiscal year (and in any event within ninety (90) days), and accompanied by an
audit report and opinion of the independent certified public accountants
selected by Lessee. Lessee will promptly furnish to Lessor any additional
information (including, but not limited to, tax returns, income statements,
balance sheets and names of principal creditors) as Lessor reasonably believes
necessary to evaluate Lessee's continuing ability to meet financial obligations.
After the effective date of the initial registration statement covering a public
offering of Lessee's securities, the term "Financial Statements" will be deemed
to refer to only those statements required by the Securities and Exchange
Commission.

14.3 OBLIGATION TO LEASE ADDITIONAL EQUIPMENT. Upon notice to Lessee, Lessor
will not be obligated to lease any Equipment which would have a Commencement
Date after said notice if: (i) Lessee is in default under this Master Lease or
any Schedule; (ii) Lessee is in default under any loan agreement, the result of
which would allow the lender or any secured party to demand immediate payment of
any material indebtedness; (iii) there is a material adverse change in Lessee's
credit standing; or (iv) Lessor determines (in reasonable good faith) that
Lessee will be unable to perform its obligations under this Master Lease or any
Schedule.

14.4 MERGER AND SALE PROVISIONS. Lessee will notify Lessor of any proposed
Merger at least sixty (60) days prior to the closing date. Lessor may, in its
discretion, either (i) consent to the assignment of the Master Lease and all
relevant Schedules to the successor entity, or (ii) terminate the Master Lease
and all relevant Schedules. If Lessor elects to consent to the assignment,
Lessee and its successor will sign the assignment documentation provided by
Lessor. If Lessor elects to terminate the Master Lease and all relevant
Schedules, then Lessee will pay Lessor all amounts then due and owing and a
termination fee equal to the present value (discounted at 6%) of the remaining
Rent for the balance of the Initial Term(s) of all Schedules, and will return
the Equipment in accordance with Section 9. Lessor hereby consents to any Merger
in which the acquiring entity has a Moody's Bond Rating of BA3 or better or a
commercially acceptable equivalent measure of creditworthiness as reasonably
determined by Lessor.
 
14.5 ENTIRE AGREEMENT. This Master Lease and associated Schedules and Summary
Equipment Schedules supersede all other oral or written agreements or
understandings between the parties concerning the Equipment including, for
example, purchase orders. ANY AMENDMENT OF THIS MASTER LEASE OR A SCHEDULE, MAY
ONLY BE ACCOMPLISHED BY A WRITING SIGNED BY THE PARTY AGAINST WHOM THE AMENDMENT
IS SOUGHT TO BE ENFORCED.

14.6 NO WAIVER. No action taken by Lessor or Lessee will be deemed to constitute
a waiver of compliance with any representation, warranty or covenant contained
in this Master Lease or a Schedule. The waiver by Lessor or Lessee of a breach
of any provision of this Master Lease or a Schedule will not operate or be
construed as a waiver of any subsequent breach.

14.7 BINDING NATURE. Each Schedule is binding upon, and inures to the benefit of
Lessor and its assigns. LESSEE MAY NOT ASSIGN ITS RIGHTS OR OBLIGATIONS.

14.8 SURVIVAL OF OBLIGATIONS. All agreements, obligations including, but not
limited to those arising under Section 6.2, representations and warranties
contained in this Master Lease, any Schedule, Summary Equipment Schedule or in
any document delivered in connection with those agreements are for the benefit
of Lessor and any Assignee or Secured Party and survive the execution, delivery,
expiration or termination of this Master Lease.

14.9 NOTICES. Any notice, request or other communication to either party by the

1.   EQUIPMENT PURCHASE

     This Schedule contemplates Lessor's acquisition of Equipment for lease to
Lessee, either by one of the first three categories listed below or by providing
Lessee with Equipment from the fourth category, in an aggregate value up to the
Commitment Amount referred to on the face of this Schedule.  If the Equipment
acquired is of category (i), (ii) , (iii) below, the effectiveness of this
Schedule as it relates to those items of Equipment is contingent upon Lessee's
acknowledgment at the time Lessor acquires the Equipment that Lessee has either
received or approved the relevant purchase documentation between vendor and
Lessor for that Equipment.

     (i)    NEW ON-ORDER EQUIPMENT. Lessor will purchase new Equipment which is
            obtained from a vendor by Lessee for its use subject to Lessor's
            prior approval of the Equipment.

     (ii)   SALE-LEASEBACK EQUIPMENT. Any in-place Equipment installed at
            Lessee's site and to which Lessee has clear title and ownership may
            be considered by Lessor for inclusion under this Lease (the "Sale-
            Leaseback Transaction"). Any request for a Sale-Leaseback
            Transaction must be submitted to Lessor in writing (along with
            accompanying evidence of Lessee's Equipment ownership satisfactory
            to Lessor for all Equipment submitted) no later than January
            3,1999*. Lessor will not perform a Sale-Leaseback Transaction for
            any request or accompanying Equipment ownership documents which
            arrive after the date marked above by an asterisk (*). Further, any
            sale-leaseback Equipment will be placed on lease subject to: (1)
            Lessor prior approval of the Equipment; and (2) if approved, at
            Lessor's actual net appraised Equipment value pursuant to the
            schedule below:

            ORIGINAL EQUIPMENT INVOICE        PERCENT OF ORIGINAL MANUFACTURER'S
                      DATE                    NET EQUIPMENT COST PAID BY LESSOR
                ------------------            ---------------------------------

            Between 12/5/98 - 10/03/99                      100%
            (90 days)  
 
     (iii)  USED ON-ORDER EQUIPMENT. Lessor will purchase used Equipment which
            is obtained from a third party by Lessee for its use subject to
            Lessor's prior approval of the Equipment and at Lessor's appraised
            value for such used Equipment.

     (iv)   800 NUMBER EQUIPMENT. Upon Lessee's use of Comdisco's 1-800 Direct
            Service, Lessor will purchase new or used Equipment from a third
            party or Lessor will supply new or used Equipment from its inventory
            for use by Lessee at rates provided by Lessor.

2.   COMMENCEMENT DATE

     The Commencement Date for each item of new on-order or used on-order
Equipment will be the install date as confirmed in writing by Lessee as set
forth on the vendor invoice of which a facsimile transmission will constitute an
original document. The Commencement Date for sale-leaseback Equipment shall be
the date Lessor tenders the purchase price. The Commencement Date for 800 Number
Equipment shall be fifteen (15) days from the ship date, such ship date to be
set forth on the vendor invoice or if unavailable on the vendor invoice the ship
date will be determined by Lessor upon other supporting shipping documentation.
Lessor will summarize all approved invoices, purchase documentation and evidence
of delivery, as applicable, received in the same calendar month into a Summary
Equipment Schedule in the form attached to this Schedule as Exhibit 1, and the
Initial Term will begin the first day of the calendar month thereafter. Each
Summary Equipment Schedule will contain the Equipment location, description,
serial number(s) and cost and will incorporate the terms and conditions of the
Master Lease and this Schedule and will constitute a separate lease.

                                       2
<PAGE>
 
3.   OPTION TO EXTEND

     So long as no Event of Default has occurred and is continuing hereunder,
and upon written notice no earlier than twelve (12) months and no later than
ninety (90) days prior to the expiration of the Initial Term of a Summary
Equipment Schedule, Lessee will have the right to extend the Initial Term of
such Summary Equipment Schedule for a period of one (1) year. In such event, the
rent to be paid during said extended period shall be mutually agreed upon and if
the parties cannot mutually agree, then the Summary Equipment Schedule shall
continue in full force and effect pursuant to the existing terms and conditions
until terminated in accordance with its terms. The Summary Equipment Schedule
will continue in effect following said extended period until terminated by
either party upon not less than ninety (90) days prior written notice, which
notice shall be effective as of the date of receipt.

4.   PURCHASE OPTION

     So long as no Event of Default has occurred and is continuing hereunder,
and upon written notice no earlier than twelve (12) months and no later than
ninety (90) days prior to the expiration of the Initial Term or the extended
term of the applicable Summary Equipment Schedule, Lessee will have the option
at the expiration of the Initial Term of the Summary Equipment Schedule to
purchase all, but not less than all, of the Equipment listed therein for a
purchase price not to exceed 15% of Lessor's cost and upon terms and conditions
to be mutually agreed upon by the parties following Lessee's written notice,
plus any taxes applicable at time of purchase. Said purchase price shall be paid
to Lessor at least thirty (30) days before the expiration date of the Initial
Term or extended term. Title to the Equipment shall automatically pass to Lessee
upon payment in full of the purchase price but, in no event, earlier than the
expiration of the fixed Initial Term or extended term, if applicable. If the
parties are unable to agree on the purchase price or the terms and conditions
with respect to said purchase, then the Summary Equipment Schedule with respect
to this Equipment shall remain in full force and effect. Notwithstanding the
exercise by Lessee of this option and payment of the purchase price, until all
obligations under the applicable Summary Equipment Schedule have been fulfilled,
it is agreed and understood that Lessor shall retain a purchase money security
interest in the Equipment listed therein and the Summary Equipment Schedule
shall constitute a Security Agreement under the Uniform Commercial Code of the
state in which the Equipment is located.

5.   TECHNOLOGY EXCHANGE OPTION

     If Lessee is not in default, and there is no material adverse change in
Lessee's credit, on or after the expiration of the 12th month of any Summary
Equipment Schedule, Lessee shall have the option to replace any of the Equipment
subject to such summary Equipment Schedule with new technology equipment ("New
Technology Equipment") utilizing the following guidelines:

A. Equipment being replaced with New Technology Equipment shall have an
aggregate original cost equal to or greater than $20,000 and be comprised of
full configurations of equipment.

B. This technology Exchange Option shall be limited to a maximum in the
aggregate of fifty percent (50%) of the original equipment cost and shall not
apply to software or any soft costs financed hereunder including but not limited
to tenant improvements and custom equipment.

C. The cost of the New Technology Equipment must be equal to or greater than the
original equipment cost of the replaced equipment, but in no event shall exceed
150% of the original equipment cost.

D. The remaining lease payments applicable to the equipment being replaced by
the New Technology Equipment will be discounted to present value at 6%.

The wholesale market value of the equipment being replaced will be established
by Comdisco based upon then current market conditions.  Upon the return of the
replaced equipment, the wholesale price will be deducted from the present value
of the remaining rentals and the differential will be added to the cost of the
New Technology Equipment in calculating the new rental.  The lease for the New
Technology Equipment will contain terms and conditions substantially similar to
those for the replaced equipment and will have an Initial Term not less than the
balance of the remaining Initial Term for the replaced equipment.

6.   DUE DILIGENCE AND LEGAL EXPENSES

     Lessee agrees to pay to Lessor due diligence and legal expenses or $2,500
upon execution hereof.

           be considered by Lessor for inclusion under this Lease (the "Sale-
           Leaseback Transaction"). Any request for a Sale-Leaseback Transaction
           must be submitted to Lessor in writing (along with accompanying
           evidence of Lessee's Equipment ownership satisfactory to Lessor for
           all Equipment submitted) no later than January 3, 1999*. Lessor will
           not perform a Sale-Leaseback Transaction for any request or
           accompanying Equipment ownership documents which arrive after the
           date marked above by an asterisk (*). Further, any sale-leaseback
           Equipment will be placed on lease subject to: (1) Lessor prior
           approval of the Equipment; and (2) if approved, at Lessor's actual
           net appraised Equipment value pursuant to the schedule below:

           ORIGINAL EQUIPMENT INVOICE   PERCENT OF ORIGINAL MANUFACTURER'S
                    DATE                NET EQUIPMENT COST PAID BY LESSOR
           --------------------------   ----------------------------------

           Between 12/5/98 - 10/03/99 (90 days) 100%
 
Lessee represents that it has paid all California sales tax due on the cost of
that portion of Equipment to be installed in California and agrees to provide
evidence of such payment to Lessor, if specifically requested.  As a result of
the election, Lessor agrees that it will not invoice Lessee for use tax on the
monthly rental rate.  Lessee understands that this is an irrevocable election to
measure the tax by the Equipment cost and cannot be changed except prior to
installation of the Equipment.

     (iii) USED ON-ORDER EQUIPMENT. Lessor will purchase used Equipment which is
           obtained from a third party by Lessee for its use subject to Lessor's
           prior approval of the Equipment and at Lessor's appraised value for
           such used Equipment.

     (iv)  800 NUMBER EQUIPMENT. Upon Lessee's use of Comdisco's 1-800 Direct
           Service, Lessor will purchase new or used Equipment from a third
           party or Lessor will supply new or used Equipment from its inventory
           for use by Lessee at rates provided by Lessor.

2.   COMMENCEMENT DATE

     The Commencement Date for each item of new on-order or used on-order
Equipment will be the install date as confirmed in writing by Lessee as set
forth on the vendor invoice of which a facsimile transmission will constitute an
original document. The Commencement Date for sale-leaseback Equipment shall be
the date Lessor tenders the purchase price. The Commencement Date for 800 Number
Equipment shall be fifteen (15) days from the ship date, such ship date to be
set forth on the vendor invoice or if unavailable on the vendor invoice the ship
date will be determined by Lessor upon other supporting shipping documentation.
Lessor will summarize all approved invoices, purchase documentation and evidence
of delivery, as applicable, received in the same calendar month into a Summary
Equipment Schedule in the form attached to this Schedule as Exhibit 1, and the
Initial Term will begin the first day of the calendar month thereafter. Each
Summary Equipment Schedule will contain the Equipment location, description,
serial number(s) and cost and will incorporate the terms and conditions of the
Master Lease and this Schedule and will constitute a separate lease.

3.   MISCELLANEOUS

     In consideration of Lessor financing software and tenant improvements
hereunder, Lessee agrees in addition to its last Monthly Rent Payment to remit
to Lessor an amount equal to 15% of Lessor's aggregate cost of software and
tenant improvements provided hereunder.

                               WARRANT AGREEMENT

             TO PURCHASE SHARES OF THE SERIES H PREFERRED STOCK OF

                             VIGNETTE CORPORATION

              DATED AS OF DECEMBER 3, 1998 (THE "EFFECTIVE DATE")
                                        

     WHEREAS, Vignette Corporation., a Delaware corporation (the "Company") has
entered into a Master Lease Agreement dated as of December 3, 1998, Equipment
Schedule No. VL-1 and VL-2 dated as of December 3, 1998, and related Summary
Equipment Schedules (collectively, the "Leases") with Comdisco, Inc., a Delaware
corporation (the "Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Leases, the right to purchase shares of its Series H Preferred Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Leases and in consideration of mutual covenants and agreements
contained herein, the Company and Warrantholder agree as follows:

1.   GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK.

     The Company hereby grants to the Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth, to
subscribe to and purchase, from the Company, 3,061 fully paid and non-assessable
shares of the Company's Series H Preferred Stock ("Preferred Stock") at a
purchase price of $16.33 per share (the "Exercise Price").  The number and
purchase price of such shares are subject to adjustment as provided in Section 8
hereof.

2.   TERM OF THE WARRANT AGREEMENT.

     Except as otherwise provided for herein, the term of this Warrant Agreement
and the right to purchase Preferred Stock as granted herein shall commence on
the Effective Date and shall be exercisable for a period of (i) seven (7) years
or (ii) three (3) years from the effective date of the Company's initial public
offering, whichever is shorter.

3.   EXERCISE OF THE PURCHASE RIGHTS.

     The purchase rights set forth in this Warrant Agreement are exercisable by
the Warrantholder, in whole or in part, at any time, or from time to time, prior
to the expiration of the term set forth in Section 2 above, by tendering to the
Company at its principal office a notice of exercise in the form attached hereto
as Exhibit I (the "Notice of Exercise"), duly completed and executed.  Promptly
upon receipt of the Notice of Exercise and the payment of the purchase price in
accordance with the terms set forth below, and in no event later than twenty-one
(21) days thereafter, the Company shall issue to the Warrantholder a certificate
for the number of shares of Preferred Stock purchased and shall execute the
acknowledgment of exercise in the form attached hereto as Exhibit II (the
"Acknowledgment of Exercise") indicating the number of shares which remain
subject to future purchases, if any.

     The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, or (ii) by surrender of Warrants ("Net Issuance") as
determined below.  If the Warrantholder elects the Net Issuance method, the
Company will issue Preferred Stock in accordance with the following formula:

     X = Y(A-B)
         ------
           A

     Where:  X =   the number of shares of Preferred Stock to be issued to the
Warrantholder.

                                      -1-
<PAGE>
 
               Y =   the number of shares of Preferred Stock requested to be
                     exercised under this Warrant Agreement.

               A =   the fair market value of one (1) share of Preferred Stock.

               B =   the Exercise Price.

     For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each share of Preferred Stock:

         (i)   if the exercise is in connection with an initial public offering
     of the Company's Common Stock, and if the Company's Registration Statement
     relating to such public offering has been declared effective by the SEC,
     then the fair market value per share shall be the product of (x) the
     initial "Price to Public" specified in the final prospectus with respect to
     the offering and (y) the number of shares of Common Stock into which each
     share of Preferred Stock is convertible at the time of such exercise;

         (ii)  if this Warrant is exercised after, and not in connection with
     the Company's initial public offering, and:

               (a)  if traded on a securities exchange, the fair market value
         shall be deemed to be the product of (x) the average of the closing
         prices over a twenty-one (21) day period ending three days before the
         day the current fair market value of the securities is being determined
         and (y) the number of shares of Common Stock into which each share of
         Preferred Stock is convertible at the time of such exercise; or

               (b)  if actively traded over-the-counter, the fair market value
         shall be deemed to be the product of (x) the average of the closing bid
         and asked prices quoted on the NASDAQ system (or similar system) over
         the twenty-one (21) day period ending three days before the day the
         current fair market value of the securities is being determined and (y)
         the number of shares of Common Stock into which each share of Preferred
         Stock is convertible at the time of such exercise;

         (iii) if at any time the Common Stock is not listed on any securities
     exchange or quoted in the NASDAQ System or the over-the-counter market, the
     current fair market value of Preferred Stock shall be the product of (x)
     the highest price per share which the Company could obtain from a willing
     buyer (not a current employee or director) for shares of Common Stock sold
     by the Company, from authorized but unissued shares, as determined in good
     faith by its Board of Directors and (y) the number of shares of Common
     Stock into which each share of Preferred Stock is convertible at the time
     of such exercise, unless the Company shall become subject to a merger,
     acquisition or other consolidation pursuant to which the Company is not the
     surviving party, in which case the fair market value of Preferred Stock
     shall be deemed to be the value received by the holders of the Company's
     Preferred Stock on a common equivalent basis pursuant to such merger or
     acquisition.

     Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number of
shares purchasable hereunder. All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.   RESERVATION OF SHARES.

     (a) Authorization and Reservation of Shares.  During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b) Registration or Listing.  If any shares of Preferred Stock required to
be reserved hereunder require registration with or approval of any governmental
authority under any Federal or State law (other than any registration under the
Securities Act of 1933, as amended ("1933 Act"), as then in effect, or any
similar Federal statute then enforced, or any state securities law, required by
reason of any transfer involved in such conversion), or listing on any domestic
securities exchange, before such shares may be issued upon conversion, the
Company will, at its expense and as expeditiously as possible, use its best
efforts to cause such shares to be duly registered, listed or approved for
listing on such domestic securities exchange, as the case may be.

5.   NO FRACTIONAL SHARES OR SCRIP.

                                      -2-
<PAGE>
 
     No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrant, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the Exercise
Price then in effect.

6.   NO RIGHTS AS SHAREHOLDER.

     This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrant.

7.   WARRANTHOLDER REGISTRY.

     The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.   ADJUSTMENT RIGHTS.

     The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

     (a) Merger and Sale of Assets.  If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation whether or not the Company is the surviving corporation, or the sale
of all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of the Warrant, the number of
shares of preferred stock or other securities of the successor corporation
resulting from such Merger Event, equivalent in value to that which would have
been issuable if Warrantholder had exercised this Warrant immediately prior to
the Merger Event.  In any such case, appropriate adjustment (as determined in
good faith by the Company's Board of Directors) shall be made in the application
of the provisions of this Warrant Agreement with respect to the rights and
interest of the Warrantholder after the Merger Event to the end that the
provisions of this Warrant Agreement (including adjustments of the Exercise
Price and number of shares of Preferred Stock purchasable) shall be applicable
to the greatest extent possible.

     (b) Reclassification of Shares.  If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of any
other class or classes, this Warrant Agreement shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable
as the result of such change with respect to the securities which were subject
to the purchase rights under this Warrant Agreement immediately prior to such
combination, reclassification, exchange, subdivision or other change.

     (c) Subdivision or Combination of Shares.  If the Company at any time shall
combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d) Stock Dividends.  If the Company at any time shall pay a dividend
payable in, or make any other distribution (except any distribution specifically
provided for in the foregoing subsections (a) or (b)) of the Company's stock,
then the Exercise Price shall be adjusted, from and after the record date of
such dividend or distribution, to that price determined by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction (i)
the numerator of which shall be the total number of all shares of the Company's
stock outstanding immediately prior to such dividend or distribution, and (ii)
the denominator of which shall be the total number of all shares of the
Company's stock outstanding immediately after such dividend or distribution.
The Warrantholder shall thereafter be entitled to purchase, at the Exercise
Price resulting from such adjustment, the number of shares of Preferred Stock
(calculated to the nearest whole share) obtained by multiplying the Exercise
Price in effect immediately prior to such adjustment by the number of shares of
Preferred Stock issuable upon the exercise hereof immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

     (e) Right to Purchase Additional Stock.  If, the Warrantholder's total cost
of equipment leased pursuant to the Leases exceeds $1,250,000, Warrantholder
shall have the right to purchase from the Company, at the Exercise Price
(adjusted as set forth herein), an additional number of shares, which number
shall be determined by (i) multiplying the amount by which the Warrantholder's
total equipment cost exceeds $1,250,000 by 4%, and (ii) dividing the product
thereof by the Exercise Price per share referenced above.

     (f) Antidilution Rights.  Additional antidilution rights applicable to the
Preferred Stock purchasable hereunder are as set forth in the Company's
Certificate of Incorporation, as amended through the Effective Date, a 

                                      -3-
<PAGE>
 
true and complete copy of which is attached hereto as Exhibit __ (the
"Charter"). The Company shall promptly provide the Warrantholder with any
restatement, amendment, modification or waiver of the Charter. The Company shall
provide Warrantholder with prior written notice of any issuance of its stock or
other equity security to occur after the Effective Date of this Warrant, which
notice shall include (a) the price at which such stock or security is to be
sold, (b) the number of shares to be issued, and (c) such other information as
necessary for Warrantholder to determine if a dilutive event has occurred.

     (g) Notice of Adjustments.  If: (i) the Company shall declare any dividend
or distribution upon its stock, whether in cash, property, stock or other
securities; (ii) the Company shall offer for subscription prorata to the holders
of any class of its Preferred or other convertible stock any additional shares
of stock of any class or other rights; (iii) there shall be any Merger Event;
(iv) there shall be an initial public offering; or (v) there shall be any
voluntary dissolution, liquidation or winding up of the Company; then, in
connection with each such event, the Company shall send to the Warrantholder:
(A) at least twenty (20) days' prior written notice of the date on which the
books of the Company shall close or a record shall be taken for such dividend,
distribution, subscription rights (specifying the date on which the holders of
Preferred Stock shall be entitled thereto) or for determining rights to vote in
respect of such Merger Event, dissolution, liquidation or winding up; (B) in the
case of any such Merger Event, dissolution, liquidation or winding up, at least
twenty (20) days' prior written notice of the date when the same shall take
place (and specifying the date on which the holders of Preferred Stock shall be
entitled to exchange their Preferred Stock for securities or other property
deliverable upon such Merger Event, dissolution, liquidation or winding up); and
(C) in the case of a public offering, the Company shall give the Warrantholder
at least twenty (20) days written notice prior to the effective date thereof.

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and (v)
the number of shares subject to purchase hereunder after giving effect to such
adjustment, and shall be given by first class mail, postage prepaid, addressed
to the Warrantholder, at the address as shown on the books of the Company.

     (h) Timely Notice.  Failure to timely provide such notice required by
subsection (g) above shall entitle Warrantholder to retain the benefit of the
applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder. The notice period shall begin
on the date Warrantholder actually receives a written notice containing all the
information specified above.

9.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a) Reservation of Preferred Stock.  The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will be
validly issued, fully paid and non-assessable, and will be free of any taxes,
liens, charges or encumbrances of any nature whatsoever; provided, however, that
the Preferred Stock issuable pursuant to this Warrant Agreement may be subject
to restrictions on transfer under state and/or Federal securities laws.  The
Company has made available to the Warrantholder true, correct and complete
copies of its Charter and Bylaws, as amended.  The issuance of certificates for
shares of Preferred Stock upon exercise of the Warrant Agreement shall be made
without charge to the Warrantholder for any issuance tax in respect thereof, or
other cost incurred by the Company in connection with such exercise and the
related issuance of shares of Preferred Stock. The Company shall not be required
to pay any tax which may be payable in respect of any transfer involved and the
issuance and delivery of any certificate in a name other than that of the
Warrantholder.

Warrant Agreement and the performance of all obligations of the Company
hereunder, including the issuance to Warrantholder of the right to acquire the
shares of Preferred Stock, have been duly authorized by all necessary corporate
action on the part of the Company, and the Leases and this Warrant Agreement are
not inconsistent with the Company's Charter or Bylaws, do not contravene any law
or governmental rule, regulation or order applicable to it, do not and will not
contravene any provision of, or constitute a default under, any indenture,
mortgage, contract or other instrument to which it is a party or by which it is
bound, and the Leases and this Warrant Agreement constitute legal, valid and
binding agreements of the Company, enforceable in accordance with their
respective terms.

     (c) Consents and Approvals.  No consent or approval of, giving of notice
to, registration with, or taking of any other action in respect of any state,
Federal or other governmental authority or agency is required with respect to
the execution, delivery and performance by the Company of its obligations under
this Warrant Agreement, except for the filing of notices pursuant to Regulation
D under the 1933 Act and any filing required by applicable state securities law,

10.  REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

     This Warrant Agreement has been entered into by the Company in reliance
upon the following representations and covenants of the Warrantholder:

                                      -5-
<PAGE>
 
     (a) Investment Purpose.  The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b) Private Issue.  The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c) Disposition of Warrantholder's Rights.  In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available.  Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required.  Whenever
the restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

     (d) Financial Risk.  The Warrantholder has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     (e) Risk of No Registration.  The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "1934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act", or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the right to purchase, it may be
required to hold such securities for an indefinite period.  The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     (f) Accredited Investor.   Warrantholder is an "accredited investor" within
the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.

11.  TRANSFERS.

     Subject to the terms and conditions contained in Section 10 hereof, this
Warrant Agreement and all rights hereunder are transferable in whole or in part

Warrants exceed three (3) transfers.  The transfer shall be recorded on the
books of the Company upon receipt by the Company of a notice of transfer in the
